Dear Stockholder:
You are cordially invited to attend a special meeting of the stockholders of Avenue Therapeutics, Inc. (“Avenue” or the “Company”), to be held on February 6, 2019, at 10:00 a.m., Eastern Time, at the offices of our legal counsel, Alston & Bird LLP, located at 90 Park Avenue, New York, New York 10016.
At the special meeting, our stockholders will be asked to consider and vote on proposals to adopt the Stock Purchase and Merger Agreement that the Company entered into on November 12, 2018, which we refer to as the “SPMA”, providing for the acquisition of the Company by InvaGen Pharmaceuticals Inc., which we refer to as “Parent” or “Buyer”, through a two-stage transaction. Upon the first stage closing (the “First Stage Closing”), Buyer will acquire a 33.3% stake in the Company on a fully-diluted basis, which we refer to as the “Stock Purchase Transaction”, for $35 million (currently expected to be 5,833,333 shares at $6.00 per share), which we refer to as the “Stock Purchase Consideration”. Upon the second stage closing (the “Second Stage Closing”), Madison Pharmaceuticals Inc., a wholly-owned subsidiary of Buyer which we refer to as “Merger Sub”, will merge with and into the Company, which we refer to as the “Merger Transaction”, with the Company surviving the Merger Transaction as a wholly-owned subsidiary of Buyer. If the SPMA is adopted by our stockholders and the Second Stage Closing is completed, each issued and outstanding share of our common stock (other than shares for which appraisal rights have been properly and validly perfected and not validly withdrawn or lost) will be converted into the right to receive (i) a pro rata portion of the total merger consideration of up to $180 million, subject to certain deductions, which portion is currently expected to be approximately $13.92 per share, without interest and less any applicable withholding taxes, which represents a premium of approximately 234.6% above the closing price of our common stock as of November 12, 2018; and (ii) a contingent value right (“CVR”) which represents the right to receive a certain contingent cash payment upon the achievement of certain milestones relating to annual net sales and gross profit targets of IV Tramadol, pursuant to a contingent value rights agreement (the “CVR Agreement”) to be entered into upon the Second Stage Closing by the Company and a rights agent (we refer to clauses (i) and (ii) hereof as the “Merger Consideration”). We refer to the Stock Purchase Consideration and the Merger Consideration together as the “SPMA Consideration”.
Following the Merger Transaction, the Company will be a wholly-owned subsidiary of Buyer.
To assist in evaluating the fairness of the SPMA and the transactions contemplated by the SPMA, including the Stock Purchase Transaction and the Merger Transaction, to the Company and our stockholders, the Board of Directors of the Company, which we refer to as the “Board”, formed a special committee of independent directors, which we refer to as the “Special Committee”, to consider and negotiate the terms and conditions of the Stock Purchase Transaction and the Merger Transaction and to make a recommendation to our Board.
The Board, acting on the unanimous recommendation of the Special Committee, unanimously determined that the SPMA and the ancillary agreements thereto, which we refer to as the “Ancillary Agreements”, and the transactions contemplated by the SPMA and the Ancillary Agreements, including the Stock Purchase Transaction and the Merger Transaction, are fair to and in the best interests of the Company and its stockholders and approved and declared advisable the SPMA and the Ancillary Agreements and the transactions contemplated by the SPMA and the Ancillary Agreements, including the Stock Purchase Transaction and the Merger Transaction, and including the appointment of a rights agent in connection with the CVR Agreement to act on behalf of our stockholders entitled to Merger Consideration. The Board unanimously recommends that the Company’s stockholders vote “FOR” the proposal to adopt the SPMA.
The enclosed proxy statement describes the SPMA, the Ancillary Agreements, the Stock Purchase Transaction, the Merger Transaction and other related matters. Copies of the SPMA and the Ancillary Agreements are also attached to the proxy statement. We urge our stockholders to read the entire proxy statement carefully (including the SPMA and the Ancillary Agreements), as it sets forth the details of the SPMA and other important information related to the Stock Purchase Transaction and the Merger Transaction.

TABLE OF CONTENTS
Your vote is very important, regardless of the number of shares of the Company’s common stock you own. Fortress, by virtue of its preferred stock ownership, controls a voting majority of our common stock. The Stock Purchase Transaction and the Merger Transaction cannot be completed unless holders of a majority of the aggregate voting power of the shares outstanding and entitled to vote on such proposal vote in favor of adoption of the SPMA. If you fail to vote on the SPMA, the effect will be the same as a vote against approval of the SPMA.
If you have any questions or need assistance voting, please contact Morrow Sodali, LLC, our proxy solicitor, by calling (toll-free) at (800) 662-5200.
Thank you in advance for your cooperation and continued support.

NOTICE OF SPECIAL MEETING OF STOCKHOLDERS

To Be Held on February 6, 2019
To the Stockholders of Avenue Therapeutics, Inc.:
NOTICE IS HEREBY GIVEN that a special meeting of the Stockholders of Avenue Therapeutics, Inc., a Delaware corporation (“Avenue” or the “Company”), will be held on February 6, 2019 at 10:00 a.m., Eastern Time, at the offices of our legal counsel, Alston & Bird LLP, located at 90 Park Avenue, New York, New York 10016, for the following purposes:
1.
To consider and vote on a proposal to approve and adopt the Stock Purchase and Merger Agreement, dated as of November 12, 2018, which we refer to as the “SPMA”, by and among the Company, InvaGen Pharmaceuticals Inc., a New York corporation, which we refer to as “Parent” or “Buyer”, and Madison Pharmaceuticals Inc., a Delaware corporation and a wholly-owned subsidiary of Buyer, which we refer to as “Merger Sub”, and the ancillary agreements thereto, which we refer to as the “Ancillary Agreements”, and the transactions contemplated by the SPMA and the Ancillary Agreements, including the Stock Purchase Transaction and the Merger Transaction (as defined below), and the appointment of a rights agent in connection with the contingent value rights agreement to be entered into between the Company and a rights agent (the “Appointment”), which we refer to as the “CVR Agreement”. Copies of the SPMA, the CVR Agreement and the other Ancillary Agreements are attached as Annex A to the accompanying proxy statement.
2.
To consider and vote on a proposal to approve the adjournment of the special meeting, if necessary or appropriate, including to solicit additional proxies if there are insufficient votes at the time of the special meeting to approve the proposal to approve and adopt the SPMA or in the absence of a quorum.
3.
To transact any other business that may properly come before the special meeting, or any adjournment or postponement of the special meeting, by or at the direction of the Board of Directors of the Company.
The SPMA, the Stock Purchase Transaction, the Merger Transaction and the other transactions which would be effected in connection with the SPMA are described more fully in the accompanying proxy statement, and we urge you to read the attached proxy statement carefully and in its entirety.
The Board of Directors of the Company, which we refer to as the “Board”, acting on the unanimous recommendation of a special committee of the Board comprised of independent directors, which we refer to as the “Special Committee”, unanimously determined that the SPMA and the Ancillary Agreements, and the transactions contemplated by the SPMA and the Ancillary Agreements, including the Stock Purchase Transaction and the Merger Transaction, are fair to and in the best interests of the Company and its stockholders and approved and declared advisable the SPMA and the Ancillary Agreements and the transactions contemplated by the SPMA and the Ancillary Agreements, including the Stock Purchase Transaction and the Merger Transaction and the Appointment. The Board made its determination after consideration of a number of factors, including the recommendation of the Special Committee.
Your vote is very important, regardless of the number of shares of the Company’s common stock you own. Generally, the Stock Purchase Transaction and the Merger Transaction cannot be completed unless holders of a majority of the aggregate voting power of the shares outstanding and entitled to vote on such proposal vote in favor of adoption of the SPMA. Fortress Biotech Inc., our parent Company, by virtue of its preferred stock ownership, controls a voting majority of our common stock. In addition, under the SPMA, the Stock Purchase Transaction is conditioned upon approval by a majority of the outstanding common stock held by non-affiliates, which condition can be waived by Parent. If you fail to vote on the SPMA, the effect will be the same as a vote against approval of the SPMA.
The Board recommends that you vote “FOR” approval of the proposal to adopt the SPMA and “FOR” approval of the proposal to approve the adjournment of the special meeting from time to time, if necessary or

appropriate, including to solicit additional proxies if there are insufficient votes at the time of the special meeting to adopt the SPMA or in the absence of a quorum.
Whether or not you plan to attend the special meeting, please complete, date, sign and return, as promptly as possible, the enclosed proxy card in the accompanying postage-paid reply envelope, or submit your proxy by telephone or the Internet. If your shares of our common stock are held in “street name” by your bank, brokerage firm or other nominee, your bank, brokerage firm or other nominee will be unable to vote your shares of our common stock without instructions from you. You should instruct your bank, brokerage firm or other nominee to vote your shares of our common stock in accordance with the procedures provided by your bank, brokerage firm or other nominee. If you fail to return your proxy card, submit your proxy by telephone or the Internet or vote in person, or if your shares are held in “street name” by your bank, brokerage firm or other nominee and you fail to instruct your bank, brokerage firm or other nominee to vote your shares of common stock, your shares of our common stock will not be counted for purposes of determining whether a quorum is present at the special meeting and will have the same effect as a vote against adoption of the SPMA.
Stockholders who do not vote in favor of the proposal to adopt the SPMA and who object in writing to the Stock Purchase Transaction and the Merger Transaction prior to the special meeting and comply with all of the applicable requirements of Section 262 of the Delaware General Corporate Law, which is summarized in the section entitled “The Special Meeting and the Stock Purchase Transaction and the Merger Transaction — Rights of Appraisal” in the accompanying proxy statement and reproduced in its entirety as Annex C to the accompanying proxy statement, will be entitled to rights of appraisal to obtain the fair value of their shares of common stock of the Company.
You may revoke your proxy before the special meeting by voting over the Internet or by telephone (only your latest Internet or telephone vote is counted) or by signing a new proxy and mailing it, in each case, in accordance with the instructions on the enclosed proxy card. In addition, you may revoke your proxy by attending the special meeting, requesting that your proxy be revoked and voting in person; however, attending the special meeting will not revoke your Internet vote, telephone vote or proxy, as the case may be, unless you specifically request it.
The Board has fixed the close of business on December 13, 2018 as the record date for determination of stockholders entitled to receive notice of, and to vote at, the special meeting and any adjournments or postponements thereof. Only stockholders of record at the close of business on the record date are entitled to receive notice of, and to vote at (in person or by proxy), the special meeting and at any adjournment or postponement thereof. You will be entitled to one vote for each share of our common stock that you owned on the record date. A complete list of our stockholders of record entitled to vote at the special meeting will be available for inspection at our principal executive offices at least 10 days prior to the date of the special meeting and continuing through the special meeting for any purpose germane to the meeting. The list will also be available at the meeting for inspection by any stockholder present at the meeting.
Only stockholders of record (including “street name” stockholders who can show that they beneficially owned our common stock on the record date), their duly appointed proxy holders and our guests may attend the special meeting. If you plan to attend the special meeting in person, please mark the designated box on the enclosed proxy card. Alternatively, if you utilize the Internet voting system, please indicate your plans to attend the special meeting when prompted to do so by the system. If you are a stockholder of record, you should bring the bottom half of the enclosed proxy card as your admission card and present the card upon entering the special meeting. If you are planning to attend the special meeting and your shares are held in street name (by a bank or broker, for example), you should ask the record owner for a legal proxy or bring your most recent account statement to the special meeting so that we can verify your ownership of Avenue stock. Please note, however, that if your shares are held in street name and you do not bring a legal proxy from the record owner, you will be able to attend the special meeting, but you will not be able to vote at the special meeting.
By order of the Board of Directors,​

The Special Meeting (page 48)
This proxy statement is being furnished to our stockholders as part of the solicitation of proxies by the Board of Directors of the Company, which we refer to as the “Board”, for use at the special meeting of the Company’s stockholders, which we refer to as the “special meeting”, to be held at on February 6, 2019 at 10:00 a.m., Eastern Time, at the offices of our legal counsel, Alston & Bird LLP, located at 90 Park Avenue, New York, New York 10016, or at any adjournment or postponement thereof.
Proposals to Be Voted on at the Special Meeting (page 48)
At the special meeting, you will be asked to consider and vote upon the following proposals:

the proposal to approve and adopt the SPMA and the Ancillary Agreements, and the consummation of the transactions contemplated thereby, including the Stock Purchase Transaction and the Merger Transaction, and the appointment of a rights agent (the “Rights Agent”) in connection with the CVR Agreement, which we refer to as the “SPMA Proposal”;

TABLE OF CONTENTS
Holders of our common stock are entitled to one vote on each matter submitted to a vote for each share of our common stock owned at the close of business on the record date.
Pursuant to the terms of the Class A Preferred Stock held by Fortress, Fortress will be entitled to cast, for each share of Class A Preferred Stock held by Fortress, the number of votes that is equal to 1.1 times a fraction, the numerator of which is the sum of  (A) the aggregate number of shares of outstanding common stock and (B) the whole shares of common stock into which the shares of outstanding the Class A Preferred Stock are convertible and the denominator of which is the aggregate number of shares of outstanding Class A Preferred Stock, or the Class A Preferred Stock Ratio. Thus, Fortress will at all times have voting control of us. Further, for a period of ten years from the date of the first issuance of shares of Class A Preferred Stock, the holders of record of the shares of Class A Preferred Stock (or other capital stock or securities issued upon conversion of or in exchange for the Class A Preferred Stock), exclusively and as a separate class, shall be entitled to appoint or elect the majority of our directors. This concentration of voting power may delay, prevent or deter a change in control, even when such a change may be in the best interests of all stockholders, could deprive our stockholders of an opportunity to receive a premium for their common stock as part of a sale of us or our assets, and might affect the prevailing market price of our common stock. Pursuant to the voting and support agreement dated November 12, 2018, entered into by Fortress and Dr. Lucy Lu with Parent and the Company, Fortress agreed, among other things, to cause all shares beneficially held by it entitled to vote at the special meeting to be voted “FOR” the SPMA Proposal and “FOR” the Adjournment Proposal.
The presence of stockholders holding a majority of the aggregate voting power of the shares outstanding and entitled to vote on a matter at the special meeting, in person or represented by proxy, constitutes a quorum for the transaction of business at the special meeting. However, if a new record date is set for an adjourned special meeting, then a new quorum will have to be established. Abstentions (as defined in the section entitled “The Special Meeting — Vote Required” beginning on page 49) are counted as present for the purpose of determining whether a quorum is present, whereas broker non-votes (as defined in the section entitled “The Special Meeting — Vote Required” beginning on page 49) are deemed to be “present” at the meeting for quorum purposes.
Vote Required (page 49)
SPMA Proposal
Approval of the SPMA Proposal requires the affirmative vote of stockholders holding a majority of the aggregate voting power of the shares outstanding and entitled to vote on such proposal, which we refer to as the “Company stockholder approval” (see the section entitled “The SPMA — Conditions to Completion of the Stock Purchase Transaction and the Merger Transaction” beginning on page 69). Fortress, by virtue of its preferred stock ownership in Avenue, controls a voting majority of our common stock. Abstentions and broker non-votes will have the same effect as a vote “AGAINST” approval of the SPMA Proposal.
However, in addition to the Company stockholder approval, which is required under Delaware law, under the SPMA Parent’s obligation to consummate the Stock Purchase Transaction is conditioned upon approval of the SPMA Proposal by a majority of our common stock held by stockholders who are not affiliates of the Company, which we refer to as the “Non-Affiliate Stockholder Approval”. For further information see the section entitled “The SPMA — Conditions to Completion of the Stock Purchase Transaction and the Merger Transaction” beginning on page 69.
Adjournment Proposal
Approval of the Adjournment Proposal requires the affirmative vote of stockholders holding a majority of the aggregate voting power of the shares outstanding present, in person or by proxy, and entitled to vote at the special meeting.
Abstentions will have the same effect as a vote “AGAINST” approval of the Adjournment Proposal, and broker non-votes will have no effect on this proposal.

TABLE OF CONTENTS
Voting by the Company’s Directors and Executive Officers (page 50)
At the close of business on the record date for the special meeting, the Company’s directors and executive officers beneficially owned and had the right to vote 745,412 shares of our common stock in the aggregate, which represents approximately 7% of the shares of our common stock entitled to vote at the special meeting.
The directors and officers have informed the Company that they currently intend to vote all such shares of our common stock:

FOR” the SPMA Proposal; and

FOR” the Adjournment Proposal.
On November 12, 2018, in connection with the entry into the SPMA, Fortress and Dr. Lucy Lu, the Company’s chief executive officer, who we refer to as “Dr. Lu”, entered into a voting and support agreement with Parent and the Company, pursuant to which Fortress and Dr. Lu agreed, among other things, to cause all shares beneficially held by them entitled to vote at the special meeting to be voted “FOR” the SPMA Proposal and “FOR” the Adjournment Proposal.
Proxies and Revocation (page 52)
Any stockholder of record entitled to vote at the special meeting may vote in person by appearing at the special meeting, or by submitting a proxy over the Internet, by telephone, or by mail using the enclosed postage-paid envelope. If you are a beneficial owner of our common stock and your shares are held in “street name”, you should instruct your bank, brokerage firm or other nominee on how to vote your shares of our common stock using the instructions provided by your bank, brokerage firm or other nominee. If you fail to submit a proxy or to vote in person at the special meeting, or you do not provide your bank, brokerage firm or other nominee with instructions, as applicable, your shares of our common stock will not be voted on the SPMA Proposal, which will have the same effect as a vote “AGAINST” approval of the SPMA Proposal, and your shares of our common stock will not have an effect on the Adjournment Proposal.
You have the right to revoke a proxy. If your shares are registered directly in your name, you may revoke your proxy or change your vote before the special meeting, by voting over the Internet or by telephone, signing a new proxy and mailing it, or attending the special meeting, requesting that your proxy be revoked and voting in person. If you hold shares in “street name” through a bank, brokerage firm or other nominee, you may submit a new, later-dated voting instruction form or contact your bank, broker or other nominee or vote in person at the special meeting if you obtain a “legal proxy”, as described in the sections entitled “The Special Meeting — Vote Required” beginning on page 49 and “The Special Meeting —  Proxies and Revocation” beginning on page 52.
The Stock Purchase Transaction and the Merger Transaction (page 23)
On November 12, 2018, the Company entered into the SPMA with Parent and the Merger Sub, providing for the acquisition of the Company by Parent, through a two-stage transaction. The first stage will be the consummation of the Stock Purchase Transaction, which we refer to as the “First Stage Closing”. The second stage will be the consummation of the Merger Transaction, which we refer to as the “Second Stage Closing”.
The Stock Purchase Transaction (page 23)
At the First Stage Closing, subject to prior satisfaction of certain closing conditions, Parent will acquire common stock representing 33.3% of the fully diluted capitalization of the Company for $35 million (currently expected to be 5,833,333 shares at $6.00 per share), which we refer to as the “Stock Purchase Transaction”.
The Merger Transaction (page 23)
At the Second Stage Closing, subject to prior satisfaction of certain closing conditions, Parent will acquire the remaining issued and outstanding capital stock of the Company by way of a reverse subsidiary

TABLE OF CONTENTS
merger transaction, in which Merger Sub will merge with and into the Company and the Company will survive as a wholly-owned subsidiary of Parent, which we refer to as the “Merger Transaction”. The total consideration for the Merger Transaction payable by Parent to the stockholders of the Company will be up to $180 million, less certain deductions. Concurrently with the execution and delivery of the SPMA, the Parent will make available an amount of up to $3.0 million in the form of a line of credit (the “Initial Financing”) to the Company. Upon the First Stage Closing, the Initial Financing shall be terminated and all principal, accrued but unpaid interest and other amounts due thereunder shall be deducted from the aggregate Merger Consideration, and thereby considered fully paid by the Company. Additionally, the Company is solely responsible for any broker fees in connection with the SPMA and the Ancillary Agreements, which shall be deducted from the Merger Consideration. In addition, the holders of our common stock immediately prior to the consummation of the Merger Transaction will receive certain contingent value rights which represent the right to receive a contingent cash payment upon the achievement of certain milestones relating to annual net sales and gross profit targets of IV Tramadol, pursuant to the CVR Agreement, without interest and less any applicable withholding taxes.
At the effective time of the Merger Transaction, among other things:

each share of our common stock issued and outstanding immediately prior to the effective time of the Merger Transaction will be automatically cancelled and (other than shares for which appraisal rights have been properly and validly perfected and not validly withdrawn or lost, which we refer to as the “Dissenting Shares”, and shares owned by the Company, Parent or Merger Sub, which we refer to as the “Cancelled Shares”) converted into the right to receive (i) a pro rata portion of the total merger consideration of up to $180 million, subject to certain deductions described further herein, which portion is currently expected to be approximately $13.92 per share, without interest and less any applicable withholding taxes, which represents a premium of approximately 234.6% over the closing price of our common stock on November 12, 2018; and (ii) one CVR (we refer to clauses (i) and (ii) hereof as the “Merger Consideration”). We refer to the Stock Purchase Consideration and the Merger Consideration together as the “SPMA Consideration”.

each of the Dissenting Shares and the Cancelled Shares will be canceled without payment of any consideration and shall cease to exist, subject to certain rights of holders of the Dissenting Shares as described below.
If the SPMA Proposal is not approved by the stockholders of the Company, or if the Merger Transaction is not completed for any other reason, then the stockholders of the Company will not receive any payment for their shares of our common stock in connection with the SPMA. Instead, we expect that the Company’s shares will continue to be registered with the SEC and quoted on Nasdaq.
When Stock Purchase Transaction and the Merger Transaction Become Effective (page 57)
If the SPMA Proposal is approved by the stockholders of the Company, the closing of the Stock Purchase Transaction shall take place no later than five business days after the satisfaction or waiver of the conditions to the closing of the Stock Purchase Transaction, including the Company obtaining the Company stockholder approval and the absence of any law or order restraining, enjoining or otherwise prohibiting the consummation of the Stock Purchase Transaction, provided for in the SPMA, which we refer to as the “First Stage Closing Conditions”, or at such later time as may be agreed by Parent and the Company in writing, as described in the section entitled “The SPMA — Conditions to Completion of the Stock Purchase Transaction and Merger Transaction” beginning on page 69 of this proxy statement.
If the SPMA Proposal is approved by the stockholders of the Company, the closing of the Merger Transaction shall take place no later than five business days after the satisfaction or waiver of the conditions to the closing of the Merger Transaction, including the Company obtaining final FDA approval of IV Tramadol on or before December 1, 2020 (or, if there are such pending queries from the FDA as of such date, then on or before April 30, 2021), the expiration or early termination of any applicable waiting period under the HSR Act, and the absence of any law or order restraining, enjoining or otherwise prohibiting the consummation of the Merger Transaction provided for in the SPMA, which we refer to as the “Second Stage Closing Conditions”, or at such later time as may be agreed by Parent and the Company in writing, as described in the section entitled “The SPMA — Conditions to Completion of the Stock Purchase Transaction and Merger Transaction” beginning on page 69 of this proxy statement.

TABLE OF CONTENTS
Reasons for the Stock Purchase Transaction and the Merger Transaction; Recommendation of the Special Committee; Recommendation of the Board; Fairness of the Stock Purchase Transaction and the Merger Transaction (page 25)
To assist in evaluating the fairness of the SPMA and the transactions contemplated thereby, including the Stock Purchase Transaction and the Merger Transaction, to the Company and our stockholders, the Board formed a special committee of independent directors to consider and negotiate the terms and conditions of the Stock Purchase Transaction and the Merger Transaction and to make a recommendation to our Board.
The Special Committee unanimously determined that the SPMA, the Ancillary Agreements and the transactions contemplated by the SPMA and the Ancillary Agreements, including the Stock Purchase Transaction and the Merger Transaction, are fair to and in the best interests of the Company and its stockholders. The Special Committee made its determination after careful consideration of a number of factors, and after consultation with the Board’s legal counsel, Alston & Bird LLP (“Alston”) and Torreya Capital (“Torreya”).
The Board unanimously determined that the SPMA and the Ancillary Agreements, and the transactions contemplated by the SPMA and the Ancillary Agreements, including the Stock Purchase Transaction and the Merger Transaction, are fair to and in the best interests of the Company and its stockholders and approved and declared advisable the SPMA and the Ancillary Agreements, and the transactions contemplated by the SPMA and the Ancillary Agreements, including the Stock Purchase Transaction and the Merger Transaction. The Board also unanimously resolved that the SPMA be submitted for consideration by the stockholders of the Company and recommended that the stockholders of the Company vote to adopt the SPMA and Ancillary Agreements and approve the transactions contemplated thereunder. The Board made its determination after careful consideration of a number of factors, including the recommendation of the Special Committee, and after consultation with Alston and Torreya.
For a description of the factors considered by the Special Committee and the Board for their recommendations, see “The Special Meeting and the Stock Purchase Transaction and the Merger Transaction  — Reasons for the Stock Purchase Transaction and the Merger Transaction; Recommendation of the Special Committee; Recommendation of the Board; Fairness of the Stock Purchase Transaction and the Merger Transaction” beginning on page 25.
The Board unanimously recommends that the Company’s stockholders vote “FOR” the SPMA Proposal and “FOR” the Adjournment Proposal.
Opinion of Oppenheimer & Co. Inc. (page 29)
In connection with the Merger Transaction, the Company’s Board received the written opinion, dated November 12, 2018, of Oppenheimer & Co. Inc., referred to as Oppenheimer, as to the fairness, from a financial point of view and as of the date of the opinion, of the Merger Consideration to be received in the Merger Transaction by holders of the Company’s common stock (excluding Fortress, Parent, Merger Sub and any of their respective affiliates). The full text of Oppenheimer’s written opinion, dated November 12, 2018, which describes the assumptions made, procedures followed, matters considered and limitations on the review undertaken, is attached to this proxy statement as Annex B. Oppenheimer’s opinion was provided to the Company’s Board in connection with its evaluation of the Merger Consideration to be received by holders of the Company’s common stock (excluding Fortress, Parent, Merger Sub and any of their respective affiliates) from a financial point of view and did not address any other aspect of the Merger Transaction or any related transaction (including, without limitation, the Stock Purchase Transaction). Oppenheimer’s opinion did not address the underlying business decision of the Company to effect the Merger Transaction or any related transaction, the relative merits of the Merger Transaction or any related transaction as compared to any alternative business strategies that might exist for the Company or the effect of any other transaction in which the Company might engage and does not constitute a recommendation to any stockholder as to how such stockholder should vote or act with respect to any matters relating to the Merger Transaction or any related transaction.

TABLE OF CONTENTS
Financing the Stock Purchase Transaction and the Merger Transaction (page 35)
Parent’s and Merger Sub’s obligations under the SPMA are not subject to, or conditioned on, the receipt or availability of any funds or financing. Parent expects to pay the consideration payable in connection with the Stock Purchase Transaction out of its generally available funds or through the issuance of equity to its sole stockholder, Cipla (EU) Limited. Parent expects to pay the consideration payable in connection with the Merger Transaction out of its generally available funds, through the issuance of equity to Cipla (EU) Limited, or by borrowing from a financial institution (except for amounts payable under the CVR Agreement, if any, which are expected to be paid from generally available funds of the Company). For more information, see “The Special Meeting and the Stock Purchase Transaction and the Merger Transaction — Financing the Stock Purchase Transaction and the Merger Transaction” beginning on page 35.
Interests of Certain Persons in Stock Purchase Transaction and the Merger Transaction (page 35)
In considering the recommendation of the Board and the Special Committee that you vote to adopt the SPMA Proposal, you should be aware that the Company’s directors and executive officers have interests in the Stock Purchase Transaction and the Merger Transaction that are different from, or in addition to, those of Company stockholders generally.
Members of the Special Committee and the Board were aware of and considered these interests, among other matters, in evaluating and negotiating the SPMA, the Ancillary Agreements, the Stock Purchase Transaction and the Merger Transaction, and in recommending to Company stockholders that the SPMA Proposal be adopted.
For more information, see the sections entitled “The Special Meeting and the Stock Purchase Transaction and the Merger Transaction — Interests of the Company’s Directors and Executive Officers in the Stock Purchase Transaction and the Merger Transaction” beginning on page 35, and “The Special Meeting and the Stock Purchase Transaction and the Merger Transaction — Reasons for the Stock Purchase Transaction and the Merger Transaction; Recommendation of the Special Committee; Recommendation of the Board; Fairness of the Stock Purchase Transaction and the Merger Transaction” beginning on page 25.
Material U.S. Federal Income Tax Consequences of the Merger Transaction (page 36)
The exchange of shares of our common stock for cash and CVRs pursuant to the Merger Transaction generally will be a taxable transaction to U.S. Holders (as defined in the section entitled “The Special Meeting and the Stock Purchase Transaction and the Merger Transaction — Material U.S. Federal Income Tax Consequences of the Merger Transaction” on page 36) for U.S. federal income tax purposes. Stockholders who are U.S. Holders will generally recognize income in an amount equal to the difference, if any, between the amount of cash and the value of the CVRs received with respect to their shares of our common stock pursuant to the Merger Transaction and their adjusted tax basis in such shares. Additionally, if certain milestones are achieved under the CVR Agreement, a U.S. Holder will generally take into its taxable income the amount of cash received with respect to such milestone payment potentially reduced by all or part of its basis in such CVR. You should read “The Special Meeting and the Stock Purchase Transaction and the Merger Transaction — Material U.S. Federal Income Tax Consequences of the Merger Transaction” beginning on page 36 for a more detailed discussion of the U.S. federal income tax consequences of the Merger Transaction. You should also consult your tax advisor for a complete analysis of the effect of the Merger Transaction on your federal, state and local and/or foreign taxes.
Overview of the SPMA (page 56)
Commercially Reasonable Efforts (page 67)
Each of the parties to the SPMA agreed to use its commercially reasonable efforts to take or cause to be taken all actions, and do or cause to be done all things, reasonably necessary, proper or advisable on its part under the SPMA, the Ancillary Agreements, and applicable legal requirements to consummate and make effective the transactions contemplated by the SPMA and the Ancillary Agreements.

The Company agreed that it shall not (and shall cause its affiliates not to), and shall not authorize or permit its representatives to, directly or indirectly:

initiate, solicit or knowingly encourage or facilitate the submission of any Takeover Proposal (as defined below) or the making of any proposal that could reasonably be expected to lead to any Takeover Proposal;

conduct or engage in, continue or otherwise participate in any discussions or negotiations with, disclose any non-public information relating to the Company to, afford access to the business, properties, assets, books, or records of the Company to, or knowingly assist, participate in, facilitate, or encourage any effort by any third party that is seeking to make, or has made, any Takeover Proposal;

amend or grant any waiver under any standstill or similar agreement with the party providing such Takeover Proposal with respect to the applicable class of equity securities of the Company;

Notwithstanding the foregoing, the Board is permitted to take the following actions:

participate in negotiations or discussions with any third party that has made (and not withdrawn) a bona fide, unsolicited Takeover Proposal in writing that the Board determines in good faith, after consultation with its outside legal counsel and independent financial advisor, constitutes or could reasonably be expected to result in a superior proposal (as defined below); and

thereafter furnish to such third party non-public information relating to the Company pursuant to an executed confidentiality and standstill agreement no less favorable to the Company than the confidentiality agreement between the Parent and the Company,
only if the Board determines in good faith, after consultation with outside legal counsel and independent financial advisor, that the failure to take such anti-Takeover Proposal would reasonably be expected to result in the Board breaching its fiduciary duties under applicable legal requirements.
Change of Recommendation; Superior Proposals (page 65)

enter into a Company Acquisition Agreement.
Despite the foregoing restrictions, at any time prior to the receipt of the Company stockholder approval, and subject to compliance with the SPMA’s requirements with respect to the special meeting and the proxy statement, and the SPMA’s restrictions with respect to solicitation and acquisition proposals, the SPMA permits each of the Special Committee and the Board to withdraw or withhold the Special Committee recommendation or the Board recommendation, as applicable, if the Special Committee determines in good faith after consultation with its outside legal counsel that the failure to do so would be inconsistent with its fiduciary duties under applicable law, which we refer to as a “change of recommendation”.
See “The SPMA — Change of Recommendation; Superior Proposals” beginning on page 65.

Termination (page 81)
The SPMA may be terminated at any time prior to the First Stage Closing:
(1) by either the Company or Parent if the First Stage Closing has not occurred by June 30, 2019; provided, however, that the right to terminate the SPMA will not be available to any party whose failure to fulfill any obligation under the SPMA has been the cause of, or has resulted in, the failure of the First Stage Closing to occur by June 30, 2019;
(2) by either the Company or Parent in the event that any governmental authority has enacted, issued, promulgated, enforced or entered any final and non-appealable law, regulation, or other order, that restrains, enjoins or otherwise prohibits the Stock Purchase Transaction;

(6) by the mutual written consent of the Company and Parent; or
(7) by either Parent or the Company, if an Event of Insolvency occurs with respect to the other party.

The SPMA may be terminated at any time prior to the Second Stage Closing:
(1) by either the Company or Parent if the Second Stage Closing has not occurred by ten business days after the Merger Transaction Closing Conditions have been met; provided, that the right to terminate the SPMA will not be available to any party whose breach of the SPMA materially contributed to the failure of the closing of the Merger Transaction to occur;
(2) by either the Company or Parent if the Merger Transaction has not been consummated by each party’s respective outside date (April 30, 2021 for termination by Parent and October 31, 2021 for termination by the Company), provided that this termination right will not be available to any party if a breach by such party of the SPMA materially contributed to the failure of the closing of the Merger Transaction to occur;

See “The SPMA — Termination” beginning on page 81.
Remedies (page 74)

Each party to the SPMA is entitled to seek equitable relief, including an injunction or injunctions to prevent breaches of the SPMA or to enforce specifically the terms and provisions of the SPMA, without any requirement for the posting of a bond or other security, in addition to any other remedy to which such party is entitled at law or in equity.
Each party has waived any right to a jury trial with respect to any litigation arising out of or relating to the SPMA or the transactions contemplated by the SPMA.
The following agreements were simultaneously executed in conjunction with the SPMA:
Stockholders Agreement
Concurrently with the execution and delivery of the SPMA, the Company, certain stockholders of the Company, including Fortress, and the Parent entered into a stockholders agreement (the “Stockholders Agreement”), pursuant to which, among other things, the Parent obtained the right to appoint three directors to the Company’s seven member Board of Directors, one of whom must qualify as an independent
10

TABLE OF CONTENTS
director (the “Parent Directors”), upon the closing of the Stock Purchase Transaction. The Stockholders Agreement also entitles the Parent to veto rights over certain Company actions in the event the Merger Transaction fails to close. A copy of the Stockholders Agreement is attached in Appendix A to this proxy statement.
Credit Agreement and Guaranty
Concurrently with the execution and delivery of the SPMA, the Company and Parent entered into a credit agreement, which we refer to as the “Credit Agreement”, pursuant to which Parent agreed to provide Initial Financing to the Company, up to the closing of the Stock Purchase Transaction. Any amounts drawn on the line of credit will be deducted from the aggregate consideration payable to the Company pursuant to the Stock Purchase Transaction. Subject to the terms and conditions described in the SPMA, the Parent may also provide interim financing to the Company in an amount of up to $7 million during the period between the Stock Purchase Transaction and the Merger Transaction. Any amounts drawn on the interim financing will be deducted from the aggregate consideration payable by Parent to Company stockholders upon the consummation of the Merger Transaction. A copy of the Credit Agreement is attached in Appendix A to this proxy statement.
Concurrently with the execution and delivery of the Credit Agreement, Fortress and the Parent entered into a guaranty (the “Guaranty”), pursuant to which Fortress guaranteed the full payment to the Parent, when due, of all amounts of  (x) all obligations of the Company to the Parent under the Credit Agreement, whether for principal interest, fees, charges, expenses or otherwise, and (y) any and all costs and expenses incurred by the Parent in enforcing any of its rights under the Guaranty.

At the First Stage Closing, the Company’s By-Laws will be amended to reflect this change in the composition of the Board. Further, pursuant to the Voting Agreement, Fortress and Dr. Lu will vote against any Takeover Proposal, any other action made in opposition to adoption of the SPMA or the Ancillary Agreements, any action reasonably expected to materially impede any of the transactions contemplated by the SPMA or the Ancillary Agreements or any action reasonably expected to result in a breach in any respect of any covenant, representation or warranty or any other obligation or agreement of the Company contained in the SPMA, or of the stockholders contained in the Voting Agreement. In addition, Fortress and Dr. Lu agreed not to transfer any Company securities held by them until the earlier of the Merger Transaction and the termination of the SPMA.

11

fundamental representations, as defined therein) is limited to $7 million, and $35 million in the aggregate. Except in the case of fraud or intentional misrepresentation, the maximum liability of Fortress solely with respect to any breach or inaccuracy of any fundamental representation is limited to $35 million. Claims agreed to or adjudicated prior to the Merger Transaction will be reduced from the Merger Consideration. Claims surviving the Merger Transaction and agreed to or adjudicated after the Merger Transaction will be reduced from amounts payable under the CVR Agreement. A copy of the Indemnification Agreement is attached in Appendix A to this proxy statement.
Waiver Agreement
Concurrently with the execution and delivery of the SPMA, the Company, the Parent and Fortress entered into a waiver agreement (the “Waiver Agreement”), pursuant to which, among other things, Fortress irrevocably waived its right to receive dividends of the Company’s common stock under the terms of the Class A Preferred Stock and any fees, payments, reimbursements or other distributions under a certain management services agreement between the Company and Fortress and the Founders Agreement, for the period from the effective date of the Waiver Agreement to the termination of Parent’s rights under Section 4 of the Stockholders Agreement. Pursuant to the Waiver Agreement, immediately prior to the closing of the Merger Transaction, Fortress will convert all of its preferred shares into common stock pursuant to the terms of the certificate of incorporation of the Company, as amended from time to time.
Restrictive Covenant Agreements
Concurrently with the execution and delivery of the SPMA, each of Dr. Lu and Fortress entered into a restrictive covenant agreement with the Parent under which, among other things, each of Dr. Lu and Fortress respectively agrees not to engage or participate in, or render services to any person engaged in, the business of hospital administered pain management anywhere in the world other than Canada, Central America, or South America, or solicit certain employees, during the pendency of the SPMA and for a period of five years after the Merger Transaction.

Upon the consummation of the First Stage Closing, the Company and Parent will enter into a registration rights agreement pursuant to which, among other things, Parent has the right to deliver to the Company a written notice requiring the Company to prepare and file with the SEC a registration statement with respect to resales of some or all registrable securities by the Parent. The Parent cannot conduct an offering pertaining to the registrable securities unless the SPMA is terminated after the First Stage Closing.
Market Price of Common Stock (page 85)
The closing price of our common stock on Nasdaq on November 12, 2018, the last trading day prior to the public announcement of the execution of the SPMA, was $4.16 per share. If the Merger Transaction is completed, you will be entitled to receive for each share of our common stock owned by you (unless you have properly exercised, and not lost, your appraisal rights with respect to such shares), (i) a pro rata portion of the total merger consideration of up to $180 million, subject to certain deductions, which portion is currently expected to be approximately $13.92 per share, without interest and less any applicable withholding taxes, which represents a premium of approximately 234.6%, over the closing price as of November 12, 2018 and (ii) one CVR, which represents the right to receive contingent cash payment pursuant to the CVR Agreement upon the achievement of certain milestones, without interest and less any applicable withholding taxes.
On December 18, 2018, the most recent practicable date before this proxy statement was mailed to our stockholders, the closing price for our common stock on Nasdaq was $5.06 per share. You are encouraged to obtain current market quotations for our common stock in connection with voting your shares of the Company’s common stock.
Appraisal Rights (page 41)
If the Merger Transaction is completed, the Company’s stockholders will be entitled to appraisal rights under Section 262 of the Delaware General Corporate Law, which we refer to as the “DGCL”. This means
12

TABLE OF CONTENTS
that if you do not vote (either in person or by proxy) in favor of the SPMA Proposal and you choose to exercise your appraisal rights, you are entitled to have the fair value of your shares of our common stock determined by the Delaware Court of Chancery and to receive payment based on that valuation in lieu of the Merger Consideration if you exactly follow the procedures set forth in Section 262 of the DGCL. The ultimate amount you receive in an appraisal proceeding may be less than, equal to or more than the amount you would have received under the SPMA.
To exercise your appraisal rights, you must submit a written demand for appraisal to the Company before the vote is taken on the SPMA Proposal and you must not vote (either in person or by proxy) in favor of the SPMA Proposal. If you fail to follow exactly the procedures set forth in Section 262 of the DGCL, you may lose your appraisal rights. See “The Special Meeting and the Stock Purchase Transaction and the Merger Transaction — Material U.S. Federal Income Tax Consequences of the Merger Transaction — Rights of Appraisal” beginning on page 41 and the text of the DGCL appraisal rights statute reproduced in its entirety as Annex C to this proxy statement. If you hold your shares of our common stock through a bank, brokerage firm or other nominee and you wish to exercise your appraisal rights, you should consult with your bank, brokerage firm or other nominee to determine the appropriate procedures for the making of a demand for appraisal by your bank, brokerage firm or other nominee. In view of the complexity of the DGCL, stockholders who may wish to pursue appraisal rights should consult their own legal and financial advisors promptly.
Regulatory Approval
No material federal or state regulatory approvals, filings or notices are required in connection with the SPMA other than (i) as may be required by the U.S. Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the “HSR Act”), (ii) the filing with the SEC of  (A) this Proxy Statement and (B) such reports under the Exchange Act as may be required in connection with the SPMA, the Stock Purchase Transaction, the Merger Transaction, and the other transactions contemplated hereby and thereby, (iii) such clearances, consents, approvals, orders, licenses, authorizations, registrations, declarations, permits, filings and notifications as may be required under applicable U.S. federal or state securities laws or the applicable requirements of Nasdaq, and (iv) the filing of the certificate of merger with the Secretary of State of Delaware. For more information, see “Regulatory Approvals Required for the Merger Transaction” beginning on page 39.
Delisting and Deregistration of Common Stock (page 40)
If the Merger Transaction is completed, Avenue will be a privately-owned company and there will be no public market for our common stock. Upon the completion of the Merger Transaction, our common stock will be delisted from Nasdaq. In addition, the registration of our common stock under Section 12 of the Exchange Act will be terminated and we will no longer file reports with the SEC.

Alternatively, if you utilize the Internet voting system, please indicate your plans to attend the special meeting when prompted to do so by the system. If you are a stockholder of record, you should bring the bottom half of the enclosed proxy card as your admission card and present the card upon entering the special meeting. If you are planning to attend the special meeting and your shares are held in street name (by a bank or broker, for example), you should ask the record owner for a legal proxy or bring your most recent account statement to the special meeting so that we can verify your ownership of Avenue stock. Please note, however, that if your shares are held in street name and you do not bring a legal proxy from the record owner, you will be able to attend the special meeting, but you will not be able to vote at the special meeting.

Q.
How many votes do I have?
A.
Each holder of our common stock is entitled to cast one vote on each matter properly brought before the special meeting for each share of our common stock that such holder owned as of the record date of December 13, 2018. As of the record date, there were 10,667,714 shares of our common stock issued and outstanding.
Q.
What is a quorum?
A.
In accordance with Delaware law (the law under which we are incorporated) and our by-laws, the presence at the special meeting, by proxy or in person, of the holders of a majority of the outstanding shares of the capital stock entitled to vote at the special meeting constitutes a quorum, thereby permitting the stockholders to conduct business at the special meeting. Abstentions, votes withheld, and broker or nominee non-votes will be included in the calculation of the number of shares considered present at the special meeting for purposes of determining the existence of a quorum. In the event that a quorum is not present at the special meeting, we expect to adjourn or postpone the special meeting until we solicit enough proxies to obtain a quorum.
Q.
How do I vote?
A.
Stockholder of Record.   If you are a stockholder of record and your shares are registered directly in your name, you may have your shares of our common stock voted on matters presented at the special meeting in any of the following ways:

In Person.   You may attend the special meeting and cast your vote there. Even if you plan to attend the meeting, it is desirable that you vote in advance of the meeting. To attend the meeting in person (regardless of whether you intend to vote your shares in person at the meeting), please mark the designated box on the enclosed proxy card. Alternatively, if you utilize the Internet voting system, please indicate your plans to attend the special meeting when prompted to do so by the system. If you are a stockholder of record, you should bring the bottom half of the enclosed proxy card as your admission card and present the card upon entering the special meeting. If you are planning to attend the special meeting and your shares are held in street name (by a bank or broker, for example), you should ask the record owner for a legal proxy or bring your most recent account statement to the special meeting so that we can verify your ownership of Avenue stock. Please note, however, that if your shares are held in street name and you do not bring a legal proxy from the record owner, you will be able to attend the special meeting, but you will not be able to vote at the special meeting.

By Proxy.   Stockholders of record have a choice of voting by proxy:

Over the Internet:   Go to the website of our tabulator, Broadridge Financial Solutions, Inc., which we refer to as “Broadridge”, at the website referenced on your proxy card. Use the vote control number printed on your enclosed proxy card to access your account and vote your shares.

Q.
What is the difference between holding shares as a stockholder of record and as a beneficial owner?
A.
If your shares of our common stock are registered directly in your name, you are considered, with respect to those shares of our common stock, the stockholder of record. This proxy statement and proxy card have been sent directly to you by the Company. As the stockholder of record, you have the right to vote in person at the meeting or to grant your voting rights directly to the Company or to a third party by a proxy duly executed or transmitted in a manner in accordance with applicable law.

If your shares of our common stock are held in “street name” through a bank, brokerage firm or other nominee, you are considered the beneficial owner of those shares. In that case, this proxy statement has been forwarded to you by your bank, brokerage firm or other nominee who is considered, with respect to those shares of our common stock, the stockholder of record. As the beneficial owner, you have the right to direct your bank, brokerage firm or other nominee how to vote your shares by following their instructions for voting. Your bank, brokerage firm or other nominee should send you, as the beneficial owner, a package describing the procedure for voting your shares (see also the next Q&A below).
Q.
How can I change or revoke my vote?
A.
You have the right to revoke a proxy. If your shares are registered directly in your name, you may revoke your proxy or change your vote before the special meeting. To do so, you must do one of the following:

Vote over the Internet or by telephone as instructed above. Only your latest Internet or telephone vote is counted. You may not change your vote over the Internet or by telephone after 11:59 p.m., Eastern Time, on February 5, 2019.

Sign a new proxy and mail it as instructed above. Only your latest dated, valid proxy received by Broadridge not later than February 5, 2019 will be counted.

Attend the special meeting, request that your proxy be revoked and vote in person as instructed above. Attending the special meeting will not revoke your Internet vote, telephone vote or proxy, as the case may be, unless you specifically request it. To attend the special meeting, please bring either (i) the bottom half of the enclosed proxy card as your admission card and present the card upon entering the special meeting or, (ii) if your shares are held in street name (by a bank or broker, for example), you should ask the record owner for a legal proxy or bring your most recent account statement to the special meeting so that we can verify your ownership of Avenue stock. For more information, please follow the instructions under “The Special Meeting — Attendance” beginning on page 49 of this proxy statement.

TABLE OF CONTENTS
Q.
What is a proxy?
A.
A proxy is your legal designation of another person, referred to as a “proxy”, to vote your shares of our common stock. The written document describing the matters to be considered and voted on at the special meeting is called a “proxy statement”. The document used to designate a proxy to vote your shares of our common stock is called a “proxy card”.
Q.
If a stockholder gives a proxy, how are the shares of common stock voted?
A.
If you vote by proxy, regardless of the method you choose to vote, the individuals named on the enclosed proxy card, and each of them, with full power of substitution, will vote your shares of our common stock in the way that you indicate. When completing the Internet or telephone processes or the proxy card, you may specify whether your shares of our common stock should be voted “FOR” or “AGAINST” or to “ABSTAIN” from voting on all, some or none of the specific items of business to come before the special meeting.

If you are a holder of record and you properly sign your proxy card but do not mark the boxes showing how your shares of our common stock should be voted on a matter, the shares of our common stock represented by your properly signed proxy will be voted “FOR” approval of the proposal to adopt the SPMA and “FOR” approval of the proposal to approve the adjournment of the special meeting, if necessary or appropriate, including to solicit additional proxies or in the absence of a quorum.
Q.
Who will solicit and pay the cost of soliciting proxies?
A.
The Company has engaged Morrow Sodali, LLC which we refer to as the “proxy solicitor”, to assist in the solicitation of proxies for the special meeting. The Company will pay the proxy solicitor a fee of $12,500. The Company has also agreed to pay a fee for each incoming and outgoing stockholder telephone call and agreed to reimburse the proxy solicitor for certain reasonable and documented fees and expenses and will also indemnify the proxy solicitor and all of its directors, officers, employees and agents against certain claims, expenses, losses, damages, liabilities and/or judgments. The Company may also reimburse banks, brokers or their agents for their expenses in forwarding proxy materials to beneficial owners of our common stock. Our directors, officers and employees may also solicit proxies by telephone, by facsimile, by mail, on the Internet or in person. They will not be paid any additional amounts for soliciting proxies.
Q.
How are votes counted?
A.
For the SPMA Proposal, you may vote “FOR”, “AGAINST” or “ABSTAIN”. Abstentions and broker non-votes will have the same effect as votes “AGAINST” approval of the proposal to adopt the SPMA.

For the Adjournment Proposal you may vote “FOR”, “AGAINST” or “ABSTAIN”. Abstentions will have the same effect as votes “AGAINST” the Adjournment Proposal. Broker non-votes will have no effect on the Adjournment Proposal.
Q.
Who will count the votes?
A.
The votes will be counted by the inspector of elections appointed for the special meeting.
Q.
If my shares of common stock are held in “street name” by my bank, brokerage firm or other nominee, will my bank, brokerage firm or other nominee vote my shares of common stock for me?
A.
Your bank, brokerage firm or other nominee will only be permitted to vote your shares of our common stock if you instruct your bank, brokerage firm or other nominee how to vote. You should follow the procedures provided by your bank, brokerage firm or other nominee regarding the voting of your shares of our common stock. Banks, brokerage firms or other nominees who hold shares in “street name” for customers generally have the authority to vote on “routine” proposals when they have not received instructions from beneficial owners. However, banks, brokerage firms and other nominees are precluded from exercising their voting discretion with respect to approving non-routine matters, such as the SPMA Proposal, and, as a result, absent specific instructions from the beneficial
17

TABLE OF CONTENTS
owner of such shares of our common stock, banks, brokerage firms or other nominees are not empowered to vote those shares of our common stock on non-routine matters, which we refer to as broker non-votes. For the purpose of the special meeting, brokers cannot execute a “routine” vote. Therefore, if you do not instruct your bank, brokerage firm or other nominee to vote your shares of our common stock, your shares of our common stock will not be voted, and as broker non-votes, the effect will be the same as a vote “AGAINST” approval of the proposal to adopt the SPMA, and your shares of our common stock will have no effect on the proposal to approve the Adjournment Proposal.
Q.
What votes are required for the Company’s stockholders to adopt the SPMA Proposal and Adjournment Proposal?
A.
The SPMA Proposal requires the affirmative vote of stockholders holding a majority of the aggregate voting power of the shares outstanding and entitled to vote on such proposals. The Adjournment Proposal requires the affirmative vote of stockholders holding a majority of the aggregate voting power of the shares outstanding and entitled to vote on such proposals that are present, in person or by proxy. The SPMA proposal cannot be completed unless holders of a majority of the aggregate voting power of the shares outstanding and entitled to vote on such proposal vote in favor of adoption of the SPMA. In addition, under the SPMA, the Stock Purchase Transaction is conditioned upon approval by a majority of the outstanding common stock held by non-affiliates which condition can be waived by Parent. Abstentions and broker non-votes will have the same effect as a vote “AGAINST” approval of the SPMA Proposal and “AGAINST” approval of the Adjournment Proposal.
Q.
What is the proposed Merger Transaction and what effects will it have on the Company?
A.
The proposed Merger Transaction is the acquisition of the Company by Parent pursuant to the SPMA. If the SPMA Proposal is approved by our stockholders and the other closing conditions under the SPMA have been satisfied or waived, Merger Sub will merge with and into the Company, with the Company being the surviving corporation. We refer to this transaction as the “Merger Transaction”. As a result of the Merger Transaction, the Company will become a wholly-owned subsidiary of Parent and will no longer be a publicly held corporation, and you, as a former holder of our common stock, will no longer have any interest in our future earnings or growth, other than the right to receive contingent cash payments pursuant to the CVR Agreement upon the achievement of certain milestones, without interest and less any applicable withholding taxes. In addition, following the Merger Transaction, our common stock will be delisted from Nasdaq, the registration of our common stock under Section 12 of the Exchange Act will be terminated and we will no longer file reports with the SEC.
Q.
What will I receive if the Merger Transaction is completed?
A.
Upon completion of the Merger Transaction, you will be entitled to receive (i) a pro rata portion of the total merger consideration of up to $180 million, subject to certain deductions, which portion is currently expected to be approximately $13.92 per share, without interest and less any applicable withholding taxes; and (ii) one CVR, which represents the right to receive contingent cash payments pursuant to the CVR Agreement upon the achievement of certain milestones, without interest and less any applicable withholding taxes, for each share of our common stock that you own, unless you have properly exercised, and not validly withdrawn or otherwise lost, your appraisal rights under the DGCL with respect to such shares. For example, if you own 100 shares of our common stock, you will receive (i) an estimated $1,392.00 in cash in exchange for your shares of our common stock, without interest and less any applicable withholding taxes, and (ii) 100 CVRs (e.g., one CVR per share), which represents the right to receive contingent cash payments upon the achievement of certain milestones, without interest and less any applicable withholding taxes. You will not own any shares of the capital stock in the surviving corporation. Please do NOT return any stock certificates you hold with your proxy card.

TABLE OF CONTENTS
Q.
When do you expect the Stock Purchase Transaction and the Merger Transaction to be completed?
A.
If the SPMA Proposal receives the Company stockholder approval, the closing of the Stock Purchase Transaction shall take place no later than five business days after the satisfaction or waiver of the conditions to the closing of the Stock Purchase Transaction provided for in the SPMA, or at such later time as may be agreed by Parent and the Company in writing, as described in the section entitled “The SPMA — Conditions to Completion of the Stock Purchase Transaction and the Merger Transaction” beginning on page 69 of this proxy statement.

The closing of the Merger Transaction shall take place no later than five business days after the satisfaction or waiver of the conditions to the closing of the Merger Transaction provided for in the SPMA, or at such later time as may be agreed by Parent and the Company in writing, as described in the section entitled “The SPMA — Conditions to Completion of the Stock Purchase Transaction and the Merger Transaction” beginning on page 69 of this proxy statement.
Q.
When will stockholders receive the Merger Consideration?
A.
At or prior to the effective time of the Merger Transaction, Parent will deposit, or cause to be deposited, a cash amount in immediately available funds necessary to pay the aggregate Merger Consideration payable to our stockholders with a paying agent mutually agreeable to the Company (at the direction of the Special Committee) and Parent, which we refer to as the “paying agent”, for the benefit of the holders of shares of our common stock.

As soon as reasonably practicable after the effective time of the Merger Transaction, and in any event within three business days thereafter, Parent and the surviving corporation will cause the paying agent to mail to each of our stockholders of record immediately prior to the effective time of the Merger Transaction (other than holders of excluded shares) (i) a letter of transmittal specifying that delivery will be effected, and risk of loss and title will pass, only upon delivery of the certificates representing shares of our common stock (or affidavits of loss in lieu of such certificates as provided in the SPMA) or the transfer of the shares of our common stock represented by book-entry to the paying agent, and (ii) instructions advising each such holder of record how to surrender his, her or its shares of our common stock in exchange for the Merger Consideration. The paying agent will pay each holder of record the aggregate Merger Consideration to which such holder is entitled after delivery or transfer of such shares. Interest will not be paid or accrue in respect of the Merger Consideration. From the effective time of the Merger Transaction until the surrender or transfer of certificates or book-entry shares, as the case may be, each such certificate or book-entry share will represent only the right to receive in exchange therefor a cash amount (after giving effect to any required tax withholdings) equal to the Merger Consideration.
Q.
What happens if the Merger Transaction is not completed?
A.
If the SPMA Proposal is not approved by the stockholders of the Company, or if the Merger Transaction is not completed for any other reason, then the stockholders of the Company will not receive any payment for their shares of our common stock in connection with the Merger Transaction. Instead, we expect that the Company’s shares will continue to be registered with the SEC and quoted on Nasdaq.

Q.
What conditions must be satisfied to complete the Stock Purchase Transaction and the Merger Transaction?
A.
The Company, Parent and Merger Sub are not required to complete the Stock Purchase Transaction and the Merger Transaction unless a number of conditions are satisfied or waived, to the extent applicable. The conditions to completion of the Stock Purchase Transaction include (i) the Company stockholder approval shall have been obtained; and (ii) the absence of any law or order that is in effect and restrains, enjoins or otherwise prohibits the consummation of the Stock Purchase Transaction. The conditions to completion of the Merger Transaction include (i) the First Stage Closing shall have occurred, and the conditions in respect thereof shall have been satisfied on or prior to the First Stage Closing; (ii) any applicable waiting period (and any extension thereof) under the HSR Act will have expired or terminated early; and (iii) the absence of any law or order that is in effect and restrains, enjoins or otherwise prohibits the consummation of the Merger Transaction. For a more complete summary of the conditions that must be satisfied or waived prior to the completion of the merger, see “The SPMA — Conditions to Completion of the Stock Purchase Transaction and Merger Transaction” beginning on page 69.
Q.
Is the Merger Transaction expected to be taxable to me?
A.
Yes. The exchange of shares of our common stock for the per share Merger Consideration of up to $180 million in cash, subject to certain deductions, pursuant to the Merger Transaction and, if certain milestones are achieved pursuant to the CVR Agreement, contingent cash payments, will both generally be taxable transactions to U.S. Holders (as defined in the section entitled “The Special Meeting and the Stock Purchase Transaction and the Merger Transaction — Material U.S. Federal Income Tax Consequences of the Merger Transaction” on page 36) for U.S. federal income tax purposes. If you are a U.S. Holder and you exchange your shares of our common stock in the Merger Transaction for cash and CVRs, you will generally recognize gain or loss in an amount equal to the difference, if any, between the amount of cash and the value of the CVRs received with respect to such shares and your adjusted tax basis in such shares. Additionally, if milestones are achieved under the CVR Agreement, you will generally recognize income in the amount of cash received with respect to such CVR milestone payment, potentially reduced by all or part of your basis in the CVR. We encourage you to read “The Special Meeting and the Stock Purchase Transaction and the Merger Transaction —  Material U.S. Federal Income Tax Consequences of the Merger Transaction” beginning on page 36 for a more detailed discussion of the U.S. federal income tax consequences of the Merger Transaction. You should also consult your tax advisor for a complete analysis of the effect of the Merger Transaction on your federal, state and local and/or foreign taxes.
Q.
Do any of the Company’s directors or officers have interests in the Stock Purchase Transaction and the Merger Transaction that may differ from or be in addition to my interests as a stockholder?
A.
In considering the recommendation of the Board with respect to the SPMA Proposal, you should be aware that our directors and executive officers have interests in the Stock Purchase Transaction and the Merger Transaction that are different from, or in addition to, the interests of our stockholders generally. The Board was aware of and considered these interests, among other matters, in evaluating and negotiating the SPMA and the Stock Purchase Transaction and the Merger Transaction, and in recommending that the SPMA be adopted by the stockholders of the Company. See “The Special Meeting and the Stock Purchase Transaction and the Merger Transaction — Interests of the Company’s Directors and Executive Officers in the Stock Purchase Transaction and the Merger Transaction” beginning on page 35.
Q.
What happens if I sell my shares of our common stock before the special meeting?
A.
The record date for stockholders entitled to vote at the special meeting is December 13, 2018. If you sell your shares of our common stock after the record date but before the special meeting, then you will retain your right to vote such shares at the special meeting but will not have the right to receive the Merger Consideration.

Q.
What happens if I sell my shares of common stock after the special meeting but before the effective time of the Merger Transaction?
A.
If you sell your shares after the special meeting but before the effective time of the Merger Transaction, then you will not have the right to receive the Merger Consideration. In order to receive the Merger Consideration, you must hold your shares of our common stock through the completion of the Merger Transaction.
Q.
What do I need to do now?
A.
We urge you to read this proxy statement carefully, including its annexes and the documents referred to as incorporated by reference in this proxy statement, and to consider how the transactions affect you. Your vote is important. If you are a stockholder of record, you can ensure that your shares are voted at the special meeting by submitting your proxy via:

mail, using the enclosed postage-paid envelope;

telephone, by calling 1-800-690-6903, toll-free from the United States, Canada and Puerto Rico, and following the recorded instructions; or

the Internet, by accessing the website referenced on your proxy card and following the instructions on the website.
If you hold your shares in “street name” through a broker, bank or other nominee you should follow the directions provided by your broker, bank or other nominee regarding how to instruct your broker, bank or other nominee to vote your shares. Without those instructions, your shares will not be voted, which will have the same effect as voting “AGAINST” the SPMA Proposal.
Even if you plan to attend the special meeting, to ensure that your shares of our common stock are voted, please submit a proxy to vote your shares of our common stock by marking, signing, dating and returning the enclosed proxy card or by using the telephone number printed on your proxy card or by using the Internet voting instructions printed on your proxy card.
Q.
Should I send in my stock certificates now?
A.
No. If the SPMA Proposal is approved, after the completion of the Merger Transaction, you will promptly, and in any event within three business days, be sent a letter of transmittal, describing how you may exchange your shares of our common stock for the Merger Consideration. If your shares of our common stock are held in “street name” through a bank, brokerage firm or other nominee, you should contact your bank, brokerage firm or other nominee for instructions as to how to effect the surrender of your “street name” shares of our common stock in exchange for the Merger Consideration. See “The SPMA — Payment of Merger Consideration and Surrender of Stock Certificates” beginning on page 59. Please do NOT return any stock certificates you hold with your proxy.
Q.
What does it mean if I get more than one proxy card or voting instruction card?
A.
If your shares of the Company’s common stock are registered differently or are held in more than one account, you will receive more than one proxy card or voting instruction card. Please complete and return all of the proxy cards or voting instruction cards you receive (or submit each of your proxies by telephone or the Internet, if available to you) to ensure that all of your shares are voted.
Q.
Am I entitled to exercise appraisal rights under the DGCL instead of receiving the Merger Consideration for my shares of the Company’s common stock?
A.
Yes. As a holder of the Company’s common stock, you are entitled to exercise appraisal rights under Section 262 of the DGCL in connection with the Merger Transaction if you take certain actions and meet certain conditions, including that you do not vote (in person or by proxy) in favor of adoption of the SPMA. See “The Special Meeting and the Stock Purchase Transaction and the Merger Transaction — Rights of Appraisal” beginning on page 41.

TABLE OF CONTENTS
THE STOCK PURCHASE TRANSACTION AND THE MERGER TRANSACTION
Background of the SPMA
The Board regularly reviews and evaluates, with the Company’s management, the Company’s business strategies, operational and financial performance, industry conditions and potential opportunities and challenges, all as part of its consideration and evaluation of the Company’s prospects and its goal of enhancing stockholder value. As part of these efforts, the Board and Company management have considered and reviewed the Company’s strategic direction and business objectives.
The following chronology summarizes key events and contacts that led to the signing of the SPMA. It does not purport to catalogue every conversation among the Board, the Special Committee, members of our management or the Board and Special Committee’s representatives and other parties with respect to the transactions contemplated by the SPMA, including the Stock Purchase Transaction and the Merger Transaction.
On May 21, 2018, the Company announced positive data from the first Phase 3 study in patients undergoing bunionectomies. On June 13, 2018, the Board, Dr. Lucy Lu, Chief Executive Officer and President of Avenue, and Mr. Joseph Vazzano, Vice President, Finance and Accounting and Principal Financial Officer, met and agreed to authorize “strategic alternative” exploration.
On May 31, 2018, the Company then engaged Torreya to explore both royalty funds and potential partnerships. This engagement led to the Company meeting or conducting calls with interested royalty fund and potential partnership parties throughout the summer of 2018. In all, 22 potential partners evaluated the Company. Parent made an initial indication of intent at the end of July 2018. The Company received two additional indications of intent from two other interested parties in August 2018.
On August 7, 2018, Torreya informed the Board, Dr. Lu, and Mr. Vazzano of a significant interest in purchasing a stake in the Company from Parent. The Board formed the Special Committee, consisting of independent Board members to discuss and evaluate a potential transaction with Parent (the “Special Committee”). The Special Committee consisted of Dr. Jay Kranzler, Dr. Jeffrey Paley and Dr. Akhtar Samad. By August 20, 2018, the Company had completed its pricing study of IV Tramadol and sent reports to interested investors. Parent provided an improved term sheet and non-binding offer that same day, which the Special Committee believed was more favorable to the Company and its stockholders than Parent’s prior proposal.
Parent’s initial offer was for 35% ownership of the Company for $35 million, followed by acquisition of the remainder of the Company for an additional $110-$200 million if IV Tramadol obtained FDA approval for moderate to moderately severe post-operative pain and was listed as a Schedule IV drug before 2021. The Company sent a counter offer on August 31, 2018.
On September 3, 2018, Parent made a new offer to the Company. The new offer was also for a two stage transaction. At the closing of the first stage, Parent would pay $35 million for shares equaling a 33.3% stake in the Company. At the Second Stage Closing, Parent would pay an additional up to $165-$185 million, as well as additional payments contingent upon the achievement of certain milestones, as long as IV Tramadol received FDA approval for moderate to moderately severe post-operative pain and was listed as a Schedule IV drug by December 2020.
On September 21, 2018, the Special Committee held a meeting with Torreya. Parent was identified as the best partner for a transaction with the Company. The Special Committee discussed impending meetings with Representatives of Cipla Ltd. at the offices of Alston & Bird LLP (“Alston”), the Company’s legal counsel, from September 25 to September 27, 2018. The parties agreed to execute the transaction as a stock purchase and merger agreement.
On September 28, 2018, the Special Committee held a meeting with Torreya. The Special Committee discussed the meetings that had taken place with the team from Parent and the then-current transaction terms. The Special Committee also discussed outstanding key issues between the parties, including the current timeline of IV Tramadol development and evaluation, financial terms to any agreement, and terms relating to the current management team. The economic terms of the proposed transaction stayed much the same as the most recent proposal from Parent, but were again evaluated by the Special Committee at this meeting.

TABLE OF CONTENTS
The board of directors of Parent, at the recommendation of Parent’s sole stockholder, Cipla (EU) Limited, was expected to meet and approve the transaction on October 4, 2018. Parent’s board of directors conditionally approved the transaction to purchase an interest in the Company and then potentially effect a merger with respect to the Company subject to certain conditions being satisfied with terms consistent with those previously negotiated. The First Stage Closing would remain a $35 million purchase of 33.3% of the Company, and the second stage would be a purchase of the remainder of the Company for up to $180 million, subject to, among other things, IV Tramadol receiving FDA approval by April 2021 with label indication of moderate to moderately severe post-operative pain and being listed as a Schedule IV drug and No Risk Evaluation and Mitigation Strategy from the FDA.
From September 28, 2018 to November 10, 2018, Dr. Lu and Mr. Vazzano, along with representatives from Parent and their respective counsels, Alston and Hughes Hubbard & Reed, LLP, exchanged drafts of the SPMA and the Ancillary Agreements. The parties also discussed the terms of a contingent value rights agreement for certain sales targets and gross profits to be paid to the former stockholders of the Company following a merger with Merger Sub.
On October 19, 2018, the Special Committee along with Torreya met to discuss the SPMA. The terms of the agreement with Parent were reviewed. The estimated second stage per share price calculation was evaluated; the valuation calculation considered a 4% fee to Torreya for its services and a fully diluted share count of 11.7 million shares, and estimated the price to be $14.78 per share at the second stage closing assuming no interim financing and no new shares being granted. The Special Committee also discussed employee incentive grants aimed at aligning key employees and consultants with shareholder interests to incentivize milestone delivery and satisfy Second Stage Closing Conditions.
On November 7, 2018, the Company’s Board (including the Special Committee), Dr. Lu, and Mr. Vazzano along with Torreya met to discuss Parent’s proposed terms to the agreement. The terms and mechanics of the transaction were reviewed, with the Board (including the Special Committee), Dr. Lu, and Mr. Vazzano discussing the $35 million price for 33.3% of the Company as the first stage closing and an aggregate second stage closing price for all of the Company’s remaining shares of up to $180 million, subject to certain deductions, and subject to the Second Stage Closing Conditions being satisfied. The CVR Agreement and its terms were also discussed. The Company’s Board (including the Special Committee), Dr. Lu, and Mr. Vazzano discussed further the Company’s current and projected budget leading to the Second Stage Closing and the Second Stage Closing price. The Company’s Board (including the Special Committee) also discussed the milestones for the Revogenex License and Polpharma Manufacturing Agreement included along with the incentive plan grants.
On November 12, 2018, the Special Committee, Company’s Board, Dr. Lu, and Mr. Vazzano met.
Alston reviewed with the Special Committee and the Board fiduciary duties owed by directors under Delaware law. Following this discussion, the Special Committee members asked a number of questions of Alston. Also attending this meeting were representatives of Oppenheimer, an investment bank engaged by the Company to provide the Company’s Board with an opinion regarding the Merger Consideration. At this meeting, Oppenheimer reviewed with the Company’s Board its financial analysis of the Merger Consideration and rendered to the Company’s Board an opinion dated November 12, 2018, to the effect that, as of that date and based on and subject to the matters described in the opinion, the Merger Consideration to be received in the Merger by holders of our common stock (excluding Fortress, Parent, Merger Sub and any of their respective affiliates) was fair, from a financial point of view, to such holders. The Special Committee then unanimously determined that the SPMA, the Ancillary Agreements, and the transactions contemplated thereby, including, without limitation, the Stock Purchase Transaction and the Merger Transaction, were advisable, fair to and in the best interests of the Company and the holders of the shares of our common stock. For the basis of the Special Committee’s determination, please see the section entitled “The Special Meeting and the Stock Purchase Transaction and the Merger Transaction — Reasons for the Stock Purchase Transaction and the Merger Transaction; Recommendation of the Special Committee; Recommendation of the Board; Fairness of the Stock Purchase Transaction and the Merger Transaction — Special Committee” beginning on page 25. The Special Committee further unanimously resolved to (i) authorize and approve, in all respects, the form, terms and provisions of the SPMA, the Ancillary Agreements and the consummation of the transactions contemplated thereby, including, without

limitation, the Stock Purchase Transaction and the Merger Transaction, (ii) recommend that the Board approve and adopt the SPMA and the Ancillary Agreements, (iii) direct that the SPMA and the Ancillary Agreements be submitted to our stockholders for approval and adoption, and (iv) recommend to our stockholders that they approve and adopt the SPMA and the Ancillary Agreements.
The Company’s full Board then met and after discussion, based amongst other things on the unanimous recommendation of the Special Committee, unanimously determined that the SPMA and the transactions contemplated by the SPMA, including the Stock Purchase Transaction and the Merger Transaction, are fair to and in the best interests of the Company and its stockholders and approved and declared advisable the SPMA, the Ancillary Agreements, and the transactions contemplated thereby, including the Stock Purchase Transaction and the Merger Transaction. For the basis of the Board’s determination, please see the section entitled “The Special Meeting and the Stock Purchase Transaction and the Merger Transaction — Reasons for the Stock Purchase Transaction and the Merger Transaction; Recommendation of the Special Committee; Recommendation of the Board; Fairness of the Stock Purchase Transaction and the Merger Transaction — Special Committee” beginning on page 24. The Board also unanimously resolved to submit the SPMA and the Ancillary Agreements for consideration by the stockholders of the Company at a special meeting of stockholders and recommended that the stockholders of the Company vote to adopt the SPMA and the Ancillary Agreements.
On November 13, 2018, the Company issued a press release announcing the execution of the SPMA. On November 14, 2018, the Company filed the press release as an exhibit to its Current Report on Form 8-K.
Reasons for the Stock Purchase Transaction and the Merger Transaction; Recommendation of the Special Committee; Recommendation of the Board; Fairness of the Stock Purchase Transaction and the Merger Transaction
Both the Special Committee and the Board believe, based on their consideration of the factors described below, that the SPMA and the transactions contemplated therein, including the Stock Purchase Transaction and the Merger Transaction, are advisable and fair to the Company’s unaffiliated stockholders.
The Special Committee
The Special Committee, with the advice and assistance of Alston and Torreya, evaluated the Stock Purchase Transaction, the Merger Transaction, the terms and conditions of the SPMA, the Ancillary Agreements and the transactions contemplated therein. Over the course of approximately four months, the Special Committee held a number of meetings to discuss the SPMA and the Ancillary Agreements. At a meeting held on November 12, 2018, the Special Committee unanimously determined that the SPMA, the Ancillary Agreements and the transactions contemplated thereby, including, without limitation, the Stock Purchase Transaction and the Merger Transaction, were advisable, fair to and in the best interests of the Company and the holders of our common stock. The Special Committee further unanimously resolved to (i) authorize and approve, in all respects, the form, terms and provisions of the SPMA, the Ancillary Agreements and the consummation of the transactions contemplated thereby, including, without limitation, the Stock Purchase Transaction and the Merger Transaction, (ii) recommend that the Board approve and adopt the SPMA Proposal, (iii) direct that the SPMA and the Ancillary Agreements be submitted to the holders of the shares of our common stock for adoption, and (iv) recommend to the holders of our common stock that they adopt the SPMA Proposal.

TABLE OF CONTENTS
In evaluating the proposed SPMA, the Ancillary Agreements and the transactions contemplated thereby, including the Stock Purchase Transaction and the Merger Transaction, the Company consulted with Alston, Torreya, Dr. Lucy Lu, the Company’s Chief Executive Officer, and considered a number of factors, including, but not limited to, the following material factors (not necessarily in order of relative importance):

the fact that, as a condition to the closing of the Stock Purchase Transaction and the Merger Transaction, the SPMA must be adopted by our stockholders, which allows for an informed vote by the stockholders on the merits of the Stock Purchase Transaction and the Merger Transaction;

the fact that Parent’s closing of the Stock Purchase Transaction is conditioned upon obtaining the Non-Affiliate Stockholder Approval;

the fact that the Merger Consideration consists of a cash payment payable at closing that provides our stockholders with certainty, liquidity and value upon consummation of the Merger Transaction, particularly in light of the relatively limited trading volume of our stock, and allows our stockholders to immediately realize a certain and fair value for their shares, thus eliminating any uncertainty in valuing the consideration to be received by such stockholders and allowing stockholders the ability to pursue other investment alternatives;

recent and historical market prices for our common stock, as compared to the Stock Purchase Consideration and the Merger Transaction consideration, including the fact that the Stock Purchase Consideration of  $6.00 per share in the First Stage Closing represents an approximate premium of 44.2% over the trading price for our common stock on November 12, 2018, the last trading day before the announcement of the initial offer, and the estimated Merger Consideration of  $13.92 per share represents a premium of 234.6% over the trading price for our common stock that same day;

the fact that Parent’s offer was the best offer relative to other offers submitted to and reviewed by the Company;

the fact that the Company retained nationally recognized legal counsel, which has extensive experience in transactions similar to the Stock Purchase Transaction and the Merger Transaction, and that Alston, together with Torreya, were involved throughout the process and updated the Special Committee directly and regularly;

Oppenheimer’s opinion, dated November 12, 2018, to the Company’s Board as to the fairness, from a financial point of view and as of such date, of the Merger Consideration to be received in the Merger Transaction by holders of the Company’s common stock (excluding Fortress, Parent, Merger Sub and any of their respective affiliates), which opinion was based on and subject to the assumptions made, procedures followed, matters considered and limitations on the review undertaken as more fully described below under the caption “Opinion of Oppenheimer & Co. Inc.”; and

the Special Committee’s review of the structure of the SPMA and the financial and other terms of the SPMA, including, among others, the following specific terms of the SPMA:

the parties’ obligations to complete the Stock Purchase Transaction and the Merger Transaction, and the commitment by Parent and Merger Sub, subject to the terms of the SPMA, to use their commercially reasonable efforts to take or cause to be taken all actions to consummate the Stock Purchase Transaction and the Merger Transaction;

the absence of a financing condition in the SPMA;

the ability of the Board, subject to certain conditions, to change its recommendation that our stockholders adopt the SPMA;

our ability to specifically enforce Parent and Merger Sub’s obligations under the SPMA in certain circumstances, including their obligation to consummate the Stock Purchase Transaction and the Merger Transaction, subject to certain conditions being met;
26

TABLE OF CONTENTS

the availability of appraisal rights under Delaware law to our stockholders who do not vote in favor of the proposal to adopt the SPMA and comply with all of the required procedures under Delaware law, which provides those eligible stockholders with an opportunity to have a Delaware court determine the fair value of their shares, which may be more than, less than, or the same as the amount such stockholders would have received under the SPMA.
The Special Committee also considered a number of factors that are discussed below relating to the procedural safeguards that it believes were and are present to ensure the fairness of the Stock Purchase Transaction and the Merger Transaction. The Special Committee believes the following factors support its determinations and recommendations and provide assurance of the advisability and fairness of the Stock Purchase Transaction and the Merger Transaction to the Company’s unaffiliated stockholders:

the Special Committee consisted solely of independent directors not affiliated with Parent;

other than their receipt of Board fees (which are not contingent upon the consummation of the Stock Purchase Transaction, the Merger Transaction, or the Special Committee’s or the Board’s recommendation or approval of the Stock Purchase Transaction and the Merger Transaction) and their interests described in “The Special Meeting and the Stock Purchase Transaction and the Merger Transaction — Interests of the Company’s Directors and Executive Officers in the Stock Purchase Transaction and the Merger Transaction” beginning on page 35, the members of the Special Committee have no financial interest in the Stock Purchase Transaction and the Merger Transaction that is different from, or in addition to, the interests of the unaffiliated stockholders generally, was given exclusive authority to, among other things, review, evaluate and negotiate the terms of the proposed Stock Purchase Transaction and the Merger Transaction, to decide not to engage in the Stock Purchase Transaction and the Merger Transaction and to consider alternatives to the Stock Purchase Transaction and the Merger Transaction, to retain its own legal and financial advisors, to determine whether to proceed with a transaction with Parent or pursue alternatives thereto, and, if a decision was made to proceed with a transaction with Parent, to review, evaluate and negotiate any such transaction;

the Special Committee was deliberate in its process, taking approximately four months to analyze and evaluate the Purchaser Group’s initial proposal and to negotiate the terms of the proposed Stock Purchase Transaction and Merger Transaction with the Purchaser Group; and

the terms and conditions of the SPMA, including the Company’s ability to terminate after October 2021 if the Merger Transaction has not occurred prior to such date, which allows the Company to ensure that the Merger Transaction is consummated as negotiated by the parties.
The Special Committee also considered a variety of potentially negative factors in its deliberations concerning the SPMA and the transactions contemplated thereby, including, but not limited to, the following (not necessarily in order of relative importance):

the fact that, subsequent to the consummation of the Merger Transaction, the Company will no longer exist as an independent public company and that the nature of the Merger Transaction as a cash transaction would prevent our stockholders from participating in any value creation the business could generate, as well as any future appreciation in our value, other than through the CVR Agreement;

the fact that the Company will be prohibited from initiating, soliciting, or knowingly encouraging or facilitating the making of, an alternative acquisition proposal, from participating in any discussions or negotiations regarding, or providing any confidential or non-public information to any person relating to an acquisition proposal, or otherwise facilitating any effort or attempt to make an acquisition proposal, subject to certain exceptions;

the fact that Parent’s and Merger Sub’s obligations to consummate the Stock Purchase Transaction and the Merger Transaction are subject to certain conditions, and the possibility that such conditions may not be satisfied, including as a result of events outside our control;
27

TABLE OF CONTENTS

the fact that if the Stock Purchase Transaction and the Merger Transaction are not consummated:

our directors and officers will have expended extensive time and effort and will have experienced significant distractions from their work during the pendency of the transaction; and

the trading price of our common stock may significantly decrease;

the fact that under the terms of the SPMA, we have agreed to conduct our business in the ordinary course and that subject to Parent’s consent, we will not take a number of specific actions related to the conduct of our business, and the possibility that these terms may limit our ability to pursue business opportunities that we would otherwise pursue;

the fact that we have incurred and will continue to incur significant transaction costs and expenses in connection with the potential transaction, regardless of whether the Stock Purchase Transaction and the Merger Transaction are consummated; and

the fact that the Merger Consideration will be taxable to our taxpaying stockholders.
The Special Committee concluded that the potential benefits that it expected the Company stockholders would achieve as a result of the Stock Purchase Transaction and the Merger Transaction outweighed the risks and potentially negative factors relevant to the Stock Purchase Transaction and the Merger Transaction.
The foregoing discussion of the information and factors considered by the Special Committee is not intended to be exhaustive but includes the material factors considered by the Special Committee. In view of the variety of factors considered in connection with its evaluation of the Stock Purchase Transaction and the Merger Transaction, the Special Committee did not find it practicable to, and did not, quantify or otherwise assign relative weights to, the specific factors considered in reaching its determination and recommendation. In addition, individual directors may have given different weights to different factors. The Special Committee did not undertake to make any specific determination as to whether any factor or any particular aspect of any factor supported or did not support its ultimate decision. The Special Committee based its recommendation on the totality of the information presented. Accordingly, the Special Committee decided that it is in the best interest of the Company and the Company’s stockholders to undertake the Stock Purchase Transaction and the Merger Transaction at this time for the reasons described above.
The foregoing discussion of the information and factors considered by the Special Committee is forward-looking in nature. This information should be read in light of the factors set forth in the section entitled “Cautionary Note Concerning Forward-Looking Statements” beginning on page 46.
Recommendation of the Board
The Board consists of seven directors. On November 12, 2018, based primarily on the unanimous recommendation of the Special Committee, as well as on the basis of the other factors described above, the Board unanimously:

determined that the SPMA and the transactions contemplated by the SPMA, including the Stock Purchase Transaction and the Merger Transaction, are advisable, fair to and in the best interests of the Company and its stockholders;

approved the SPMA and the transactions contemplated by the SPMA, including the Stock Purchase Transaction and the Merger Transaction; and

resolved to recommend that the Company’s stockholders vote “FOR” the transactions contemplated by the SPMA.
The Board unanimously recommends that you vote “FOR” the SPMA proposal.
The Board believes, based on their considerations of the factors described above, that the SPMA and the transactions contemplated therein, including the Stock Purchase Transaction and the Merger Transaction, are advisable and fair to the Company’s unaffiliated stockholders. In accepting the Special Committee’s recommendations and concluding that the SPMA, the Ancillary Agreements and the transactions contemplated therein, including the Stock Purchase Transaction and the Merger Transaction,
28

TABLE OF CONTENTS
are in the best interests of the Company and the unaffiliated stockholders, our Board consulted with Alston, considered and relied upon the same factors and considerations that the Special Committee relied upon, as described above, and adopted as its own analysis the Special Committee’s analyses and conclusions in their entirety.
Opinion of Oppenheimer & Co. Inc.
The Company engaged Oppenheimer in connection with the Merger Transaction solely to render an opinion to the Company’s Board with respect to, the fairness, from a financial point of view, of the Merger Consideration to be received in the Merger Transaction by holders of the Company’s common stock (excluding Fortress, Parent, Merger Sub and any of their respective affiliates). On November 12, 2018, at a meeting of the Company’s Board held to evaluate the Stock Purchase Transaction and the Merger Transaction, Oppenheimer rendered to the Company’s Board an opinion, dated November 12, 2018, to the effect that, as of that date and based on and subject to the matters described in its opinion, the Merger Consideration was fair, from a financial point of view, to holders of the Company’s common stock (excluding Fortress, Parent, Merger Sub and any of their respective affiliates).
The full text of Oppenheimer’s written opinion, dated November 12, 2018, which describes the assumptions made, procedures followed, matters considered and limitations on the review undertaken, is attached to this proxy statement as Annex B and is incorporated by reference in its entirety. Oppenheimer’s opinion was provided to the Company’s Board in connection with its evaluation of the Merger Consideration from a financial point of view to holders of the Company’s common stock (excluding Fortress, Parent, Merger Sub and any of their respective affiliates) and did not address any other aspect of the Merger Transaction or any related transaction (including, without limitation, the Stock Purchase Transaction). Oppenheimer’s opinion did not address the underlying business decision of the Company to effect the Merger Transaction or any related transaction, the relative merits of the Merger Transaction or any related transaction as compared to any alternative business strategies that might exist for the Company or the effect of any other transaction in which the Company might engage and does not constitute a recommendation to any stockholder as to how such stockholder should vote or act with respect to any matters relating to the Merger Transaction or any related transaction. This summary of Oppenheimer’s opinion is qualified in its entirety by reference to the full text of its opinion.
In arriving at its opinion, Oppenheimer:

reviewed final execution versions of the SPMA and the CVR Agreement;

reviewed publicly available audited financial statements of the Company as of December 31, 2016 and December 31, 2017, for the period from February 9, 2015 (inception) through December 31, 2015, and for the fiscal years ended December 31, 2016 and December 31, 2017, and publicly available unaudited financial statements of the Company as of, and for the six months ended, June 30, 2017 and June 30, 2018;

reviewed financial forecasts and estimates relating to the Company (giving effect to the achievement of the development milestones on which the closing of the Merger Transaction is conditioned) prepared by the management of the Company, including estimates of contingent value payments pursuant to the CVR Agreement;

reviewed estimates of certain deductions to the $180 million of the aggregate Merger Consideration provided to or discussed with Oppenheimer by the management of the Company;

held discussions with the senior management team of the Company with respect to the business and prospects of the Company, including the liquidity needs of, and capital resources available to, the Company, and the results of the Company’s solicitation of third parties regarding a possible acquisition of all or a part of the Company;

reviewed and analyzed certain publicly available financial information for companies that Oppenheimer deemed relevant in evaluating the Company;
29

TABLE OF CONTENTS

analyzed the estimated present value of the future cash flows of the Company (giving effect to the achievement of the development milestones on which the closing of the Merger Transaction is conditioned) and the contingent value payments pursuant to the CVR Agreement based on financial forecasts and estimates prepared by the management of the Company;

reviewed historical market prices and trading volumes for the Company’s common stock;

reviewed other public information concerning the Company; and

performed such other analyses, reviewed such other information and considered such other factors as Oppenheimer deemed appropriate.
In rendering its opinion, Oppenheimer assumed and relied upon, without independent verification or investigation, the accuracy and completeness of all of the financial and other data and information provided to or discussed with Oppenheimer by the Company and its employees, representatives and affiliates or otherwise reviewed by Oppenheimer. With respect to the financial forecasts and estimates relating to the Company (including estimates of the contingent value payments pursuant to the CVR Agreement) and estimates of certain deductions to the $180 million of the aggregate Merger Consideration referred to above, Oppenheimer assumed, at the Company’s direction, and without independent verification or investigation, that such forecasts and estimates were prepared reasonably and on bases reflecting the best available information, estimates and judgments of the management of the Company as to the future financial condition and operating results of the Company (giving effect to the achievement of the development milestones on which the closing of the Merger Transaction is conditioned) and the other matters covered thereby, that the financial results reflected in the financial forecasts and estimates relating to the Company referred to above would be achieved at the times and in the amounts projected, and that any differences between the actual contingent value payments pursuant to the CVR and deductions to the aggregate Merger Consideration and the estimates thereof referred to above would not be material in any respect to Oppenheimer’s analyses or opinion. Oppenheimer expressed no view as to any of the foregoing forecasts or estimates or the assumptions or bases therefor. Among other things, the financial forecasts and estimates relating to the Company referred to above reflected assumptions regarding future equity financing transactions needed to fund projected cash shortfalls. The Company advised Oppenheimer, and Oppenheimer assumed, at the Company’s direction, and without independent verification or investigation, that, in the absence of the Stock Purchase Transaction and related debt financings to be provided by the Company, the Company would be required to pursue external financing alternatives on terms that would likely be no more favorable to the Company than those of the Stock Purchase Transaction and such related debt financings.
At the direction of the Company’s representatives, Oppenheimer also assumed that the final terms of the SPMA and the CVR Agreement would not vary materially from those set forth in the execution versions reviewed by Oppenheimer. Oppenheimer also assumed, with the consent of the Company, that the Merger Transaction and related transactions (including, without limitation, the Stock Purchase Transaction and the related debt financings to be provided by Parent) would be consummated in accordance with their respective terms without waiver, modification or amendment of any material term, condition or agreement and in compliance with all applicable laws and other requirements and that, in the course of obtaining the necessary regulatory or third party approvals, consents and releases with respect to the Merger Transaction or any related transaction, no delay, limitation, restriction or condition would be imposed that would have an adverse effect on the Company or the Merger Transaction. Oppenheimer neither made nor obtained any independent evaluations or appraisals of the assets or liabilities, contingent or otherwise, of the Company. In addition, Oppenheimer assumed that any further adjustments to the Merger Consideration pursuant to the SPMA (as to which further adjustments Oppenheimer expressed no opinion) would not be material in any respect to its analyses or opinion. Oppenheimer also assumed that the circumstances under which the Subsequent Period would terminate prior to December 31, 2036 pursuant to the CVR Agreement would not occur.
Oppenheimer did not express any opinion as to the underlying valuation, future performance or long term viability of the Company, the actual value of the Company’s common stock when issued in the Stock Purchase Transaction or the price at which the Company’s common stock would trade at any time. Oppenheimer was not requested to, and it did not, participate in the negotiation or structuring of the
30

TABLE OF CONTENTS
Merger Transaction or any related transaction. In connection with its engagement, Oppenheimer was not requested to, and it did not, solicit third party indications of interest in the possible acquisition of all or a part of the Company. Oppenheimer expressed no view as to, and its opinion did not address, any terms or other aspects or implications of the Merger Transaction (other than the Merger Consideration to the extent expressly specified in Oppenheimer’s opinion) or any related transaction or any aspect or implication of any other agreement, arrangement or understanding entered into in connection with the Merger Transaction or any related transaction or otherwise, including, without limitation, the form or structure of the Merger Consideration (including the allocation of the Merger Consideration between the non-contingent cash portion and the CVR and the related definitions and/or calculations agreed upon by the Company and Parent), any consideration to be paid or received in, or any other terms of, the Stock Purchase Transaction, the related financings to be provided by Parent or the contemplated waiver and termination agreement, restrictive covenant agreement and indemnification agreement to be entered into by Fortress, the treatment in the Merger Transaction of Class A Preferred Shares, stock options, restricted shares, restricted share units, or Company Warrants, or the fairness of the amount or nature of the compensation resulting from the Merger Transaction to any individual officers, directors or employees of the Company, or class of such persons, relative to the Merger Consideration. Oppenheimer’s opinion was necessarily based on the information available to it and general economic, financial and stock market conditions and circumstances as they existed and could be evaluated by Oppenheimer on the date of its opinion. Although subsequent developments may affect this Opinion, Oppenheimer does not have any obligation to update, revise or reaffirm its opinion. Except as described in this summary, the Company imposed no other instructions or limitations on Oppenheimer with respect to the investigations made or the procedures followed by it in rendering its opinion.
This summary is not a complete description of Oppenheimer’s opinion or the financial analyses performed and factors considered by Oppenheimer in connection with its opinion. The preparation of a financial opinion is a complex analytical process involving various determinations as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances and, therefore, a financial opinion is not readily susceptible to summary description. Oppenheimer arrived at its ultimate opinion based on the results of all analyses undertaken by it and assessed as a whole, and did not draw, in isolation, conclusions from or with regard to any one factor or method of analysis for purposes of its opinion. Accordingly, Oppenheimer believes that its analyses and this summary must be considered as a whole and that selecting portions of its analyses and factors or focusing on information presented in tabular format, without considering all analyses and factors or the narrative description of the analyses, could create a misleading or incomplete view of the processes underlying Oppenheimer’s analyses and opinion.
In performing its analyses, Oppenheimer considered industry performance, general business, economic, market and financial conditions and other matters existing as of the date of its opinion, many of which are beyond the Company’s control. No company, business or transaction used in the analyses is identical to the Company or the Merger Transaction, and an evaluation of the results of those analyses is not entirely mathematical. Rather, the analyses involve complex considerations and judgments concerning financial and operating characteristics and other factors that could affect the acquisition, public trading or other values of the companies, business segments or transactions analyzed.
The assumptions and estimates contained in Oppenheimer’s analyses and the ranges of valuations resulting from any particular analysis are not necessarily indicative of actual values or future results, which may be significantly more or less favorable than those suggested by its analyses. In addition, analyses relating to the value of businesses or securities do not purport to be appraisals or to reflect the prices at which businesses or securities actually may be sold or acquired. Accordingly, the assumptions and estimates used in, and the results derived from, Oppenheimer’s analyses are inherently subject to substantial uncertainty.
Oppenheimer was not requested to, and it did not, recommend the specific consideration payable in the Merger Transaction. The type and amount of consideration payable in the Merger Transaction was determined through negotiation between the Company and Parent and was approved by the Board. The decision to enter into the SPMA was solely that of the Board. Oppenheimer’s opinion and financial analysis
31

TABLE OF CONTENTS
were only one of many factors considered by the Board in its evaluation of the Merger Transaction and should not be viewed as determinative of the views of the Board, the Special Committee or management with respect to the Merger Transaction or the consideration payable in the Merger Transaction.
The following is a summary of the material financial analyses reviewed with the Company’s Board in connection with Oppenheimer’s opinion dated November 12, 2018. The financial analyses summarized below include information presented in tabular format. In order to fully understand Oppenheimer’s financial analyses, the tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the financial analyses. Considering the data in the tables below without considering the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of Oppenheimer’s financial analyses.
For purposes of the “Selected Companies Analysis” and “Discounted Free Cash Flow to Equity Analysis” summarized below, the “illustrative net present value range of the Merger Consideration as of December 31, 2018” of  $12.12 to $13.28 refers to the range of illustrative values of the Merger Consideration discounted to December 31, 2018 by applying discount rates ranging from 21.1% to 23.1% to the following:

the cash portion of the Merger Consideration to be received at the closing of the Merger Transaction (assumed to occur on April 1, 2021 per the management of the Company) based on estimates provided by the management of the Company; and

the implied value of the CVR portion of the Merger Consideration based on the future contingent cash payments projected to be paid pursuant to the CVR following the closing of the Merger Transaction until December 31, 2036 using financial forecasts and estimates prepared by the management of the Company.
Selected Companies Analysis.
Oppenheimer reviewed publicly available financial and stock market information of the Company and the following eight selected publicly traded companies with late-stage product candidates in the pain management segment of the specialty pharmaceuticals industry:

Pacira Pharmaceuticals, Inc.

Collegium Pharmaceutical, Inc.

AcelRx Pharmaceuticals, Inc.

Recro Pharma, Inc.

DURECT Corporation

Cumberland Pharmaceuticals Inc.

KemPharm, Inc.

Trevena, Inc.
Oppenheimer reviewed enterprise values of the selected companies, calculated as fully-diluted market value based on closing stock prices on November 9, 2018, plus debt and non-controlling interests, less cash, of the selected companies. Financial data for the selected companies was based on public filings. The overall low to high range of enterprise values observed for the selected companies were $4.3 million to $1,987.5 million (with a median of  $149.3 million). Oppenheimer then applied the Company’s cash as of September 30, 2018 (as provided by the Company’s management) to a selected range of enterprise values of $134.4 million to $164.2 million derived from the selected companies. Based on the fully-diluted shares of the Company’s common stock using the Company’s capitalization data set forth in the SPMA (the “SPMA Share Count”) and also based on the estimated fully-diluted shares of the Company’s common stock (as provided by the management of the Company), including estimated additional shares that would be issued by the Company in future equity financing transactions absent the Stock Purchase Transaction and the
32

TABLE OF CONTENTS
Merger Transaction (the “Estimated Affected Share Count”), this analysis indicated the following approximate implied per share equity reference ranges for the Company, as compared to the illustrative net present value range of the Merger Consideration as of December 31, 2018:
Implied Per Share Equity Reference Ranges based on:
Illustrative Net Present Value
Range of Merger Consideration
SPMA Share Count
Estimated Affected Share Count
$11.79 to $14.35
$4.18 to $5.08
$12.12 to $13.28
Discounted Free Cash Flow to Equity Analysis.
Oppenheimer performed a discounted free cash flow to equity analysis to calculate the estimated present value of the standalone after-tax free cash to equity flows that the Company was forecasted to generate during the fiscal years ending December 31, 2019 through December 31, 2036. Financial data of the Company were based on financial forecasts and estimates prepared by the management of the Company. Oppenheimer calculated terminal values for the Company by applying to the Company’s estimated fiscal year 2036 free cash flow to equity a selected range of declining perpetuity growth percentages of 4.0% to 3.0%. The free cash flows to equity and terminal values were then discounted to present value as of December 31, 2018 using discount rates ranging from 21.1% to 23.1%. Based on the estimated fully-diluted shares of the Company’s common stock (as provided by the management of the Company), including estimated additional shares that would be issued by the Company in future equity financing transactions absent the Stock Purchase Transaction and the Merger Transaction, this analysis indicated the following approximate implied per share equity reference range for the Company, as compared to the illustrative net present value range of the Merger Consideration as of December 31, 2018:
Implied Per Share Equity
Reference Ranges based on:
Illustrative Net Present Value
Range of Merger Consideration
$7.22 to $8.76
$12.12 to $13.28
Other Factors.
Oppenheimer also reviewed, for informational purposes, historical trading prices of the Company’s common stock during the 52-week period ending November 9, 2018.
Miscellaneous
The Company agreed to pay Oppenheimer for its financial advisory services with respect to rendering its opinion in connection with the Merger Transaction a fee of  $500,000 upon delivery of Oppenheimer’s opinion. The Company also has agreed to reimburse Oppenheimer for its reasonable expenses, including reasonable fees and expenses of its legal counsel, and to indemnify Oppenheimer and related parties against liabilities, including liabilities under the federal securities laws, relating to, or arising out of, its engagement. Oppenheimer and its affiliates in the past performed investment banking and other services for the Company unrelated to the Merger Transaction, for which services Oppenheimer and its affiliates received compensation, including having acted as sole book-running manager in connection with the initial public offering of the Company in 2017. In the ordinary course of business, the Company and its affiliates may actively trade securities of the Company for its and their affiliates’ own accounts and for the accounts of customers and, accordingly, may at any time hold a long or short position in such securities.
The issuance of Oppenheimer’s opinion was approved by an authorized committee of Oppenheimer. The Company selected Oppenheimer to provide certain financial advisory services in connection with the Merger Transaction based on Oppenheimer’s reputation and experience and its familiarity with the Company and its business. Oppenheimer is an internationally recognized investment banking firm and, as a part of its investment banking business, is regularly engaged in valuations of businesses and securities in connection with acquisitions and mergers, underwritings, secondary distributions of securities, private placements and valuations for other purposes.

After the effective time of the Merger Transaction, Parent will wholly own the operations of the Company and the Company will cease to be a public company. If the Merger Transaction is consummated, the Company’s common stock will no longer be quoted on Nasdaq, the registration of the Company’s common stock under Section 12 of the Exchange Act will be terminated and the Company will no longer file reports with the SEC.
After the effective time of the Merger Transaction, the members of the board of directors of Merger Sub immediately prior to the effective time of the Merger Transaction will be appointed as the directors of the Company, and the officers of Merger Sub immediately prior to the effective time of the Merger Transaction will be appointed as the officers of the Company, in each case until the earlier of their resignation or removal or until their respective successors are duly elected or appointed and qualified, as the case may be.
Certain Effects of the Merger Transaction
If the SPMA is adopted by the Requisite Stockholder Approval and the other conditions to the closing of the Merger Transaction are either satisfied or waived, then Merger Sub will be merged with and into the Company, the separate company existence of Merger Sub will cease, and the Company will continue its corporate existence under Delaware law as the surviving corporation in the Merger Transaction, with all of its rights, privileges, immunities, powers and franchises continuing unaffected by the Merger Transaction.
Upon consummation of the Merger Transaction, each share of our common stock issued and outstanding immediately prior to the effective time of the Merger Transaction (other than the excluded shares) will immediately be converted into the right to receive the Merger Consideration.
Following the Merger Transaction, the entire equity in the surviving corporation will be owned by Parent. As a result, if the Merger Transaction is completed, Parent and the Purchaser Group will be the sole beneficiaries of the Company’s future earnings and growth, if any (except the Company’s stockholders’ right to receive contingent cash payments pursuant to the CVR Agreement upon the achievement of certain milestones), and will own all of the shares entitled to vote on any matter submitted to the Company’s stockholders. Likewise, the Purchaser Group will also bear the risks of ongoing operations, including the risks of any decrease in the Company’s value after the Merger Transaction.
In connection with the Merger Transaction, the Purchaser Group Members will receive benefits and be subject to obligations that are different from, or in addition to, the benefits received by the Company’s stockholders generally. The primary benefits of the Merger Transaction to the Purchaser Group Members, based on their direct or indirect ownership of all the equity interests in Parent, include their interest in the Company’s potential future earnings and growth which, if they successfully execute their business strategies, could be substantial. Subject to certain use limitations imposed by applicable law, following the Merger Transaction, the Company’s net operating losses and research and development tax credits will also inure to the benefit of the Purchaser Group. In addition, following the Merger Transaction, the Company will be a private company, and therefore, the Company and its beneficial owners will be relieved of the applicable restrictions imposed on companies with publicly traded equity.
The primary detriments of the Merger Transaction to the Purchaser Group Members include the fact that all of the risk of any possible increase in the Company’s net losses or any potential decrease in the Company’s future value following the Merger Transaction will be borne by Parent. Additionally, the investment by the Purchaser Group in the Company will not be liquid, with no public trading market for such securities.
Except as provided in the employment agreements of certain Company employees in connection with termination, if any, of employment in connection with a change of control, there are no change in control payments, transaction bonuses or other extraordinary bonuses payable to the Company’s management or employees as a result of the transactions contemplated by the SPMA. It is currently intended that Dr. Lu will continue to serve as President and Chief Executive Officer of the surviving corporation following the Merger Transaction on substantially the same terms as Dr. Lu currently serves the Company.

TABLE OF CONTENTS
Shares of our common stock are currently registered under the Exchange Act and are quoted on Nasdaq under the symbol “ATXI”. As a result of the Merger Transaction, Avenue will be a privately held corporation and there will be no public market for its shares. After the Merger Transaction, shares of our common stock will cease to be listed on Nasdaq and price quotations with respect to sales of shares of our common stock in the public market will no longer be available. In addition, registration of our common stock under the Exchange Act will be terminated.
At the effective time of the Merger Transaction, the Company’s certificate of incorporation and by-laws will be amended and restated to read as set forth in Exhibits M and N, respectively, to the SPMA, will be the certificate of incorporation and by-laws of Avenue following the Merger Transaction until thereafter amended in accordance with their respective terms and the DGCL.
Financing the Stock Purchase Transaction and the Merger Transaction
Parent and Merger Sub’s obligations under the SPMA are not subject to, or conditioned on, the receipt or availability of any funds or financing. Parent expects to pay the consideration payable in connection with the Stock Purchase Transaction out of its generally available funds or through the issuance of equity to its sole stockholder, Cipla (EU) Limited. Parent expects to pay the consideration payable in connection with the Merger Transaction out of its generally available funds, through the issuance of equity to Cipla (EU) Limited, or by borrowing from a financial institution (except for amounts payable under the CVR Agreement, if any, which are expected to be paid from generally available funds of the Company). For more information, see “The Special Meeting and the Stock Purchase Transaction and the Merger Transaction —  Financing the Stock Purchase Transaction and the Merger Transaction” beginning on page 35.
Interests of the Company’s Directors and Executive Officers in the Stock Purchase Transaction and the Merger Transaction
In considering the recommendations of the Special Committee and of the Board with respect to the SPMA, you should be aware that, aside from their interests as stockholders of the Company, the Company’s directors and executive officers have interests in the Stock Purchase Transaction and the Merger Transaction that may be different from, or in addition to, those of other stockholders of the Company generally. The members of the Special Committee were aware of and considered these interests, among other matters, in evaluating and negotiating the SPMA, the Ancillary Agreements, the Stock Purchase Transaction, the Merger Transaction, and in making its recommendations to the Board, which was also aware of and took into account these interests, among other matters, when making its recommendation to the stockholders of Avenue that the SPMA be adopted. See “The Special Meeting and the Stock Purchase Transaction and the Merger Transaction — Background of the SPMA” beginning on page 23 and “The Special Meeting and the Stock Purchase Transaction and the Merger Transaction — Reasons for the Stock Purchase Transaction and the Merger Transaction; Recommendation of the Special Committee; Recommendation of the Board; Fairness of the Stock Purchase Transaction and the Merger Transaction” beginning on page 25.
The Company’s stockholders should take these interests into account in deciding whether to vote “FOR” the adoption of the SPMA. These interests are described in more detail below.
Indemnification and Insurance
The Company’s certificate of incorporation provides for indemnification of directors and executive officers against certain liabilities that may arise by reason of their status or service as directors or officers. In addition, pursuant to the SPMA, the Company’s directors and executive officers will be entitled to certain ongoing indemnification from Parent and the surviving corporation and coverage under directors’ and officers’ liability insurance policies. The indemnification and insurance provisions in the SPMA are further described in the section entitled “The SPMA — Indemnification; Directors’ and Officers’ Insurance” on page 67.
Interests of the Special Committee
The Special Committee consists of three members of the Board; Dr. Jay Kranzler, Dr. Jeffrey Paley, and Dr. Akhtar Samad. In consideration of the time and effort required of the members of the Special
35

TABLE OF CONTENTS
Committee in connection with evaluating the proposed Stock Purchase Transaction and the Merger Transaction and any related transactions, the Board adopted resolutions providing that the Company would pay all expenses incurred by the Special Committee, including the fees and expenses of its financial, legal and other advisers.
Voting by the Company’s Directors and Executive Officers
At the close of business on the record date for the special meeting, the Company’s directors and executive officers beneficially owned and had the right to vote 745,412 shares of our common stock, which represents approximately 7% of the shares of our common stock entitled to vote at the special meeting.
The directors and officers have informed the Company that they currently intend to vote all such shares of our common stock:

FOR” the SPMA Proposal; and

FOR” the Adjournment Proposal.
Further, pursuant to the Voting and Support Agreement, Dr. Lu shall cause all shares beneficially held by her entitled to vote at the special meeting to be voted “FOR” the SPMA Proposal and “FOR” the Adjournment Proposal.
Golden Parachute Compensation
SEC rules would require us to disclose and conduct an advisory vote on the compensation that would be payable to our named executive officers based on or that otherwise relates to the SPMA. Consummation of the Merger Transaction, however, will not trigger any such payments. Accordingly, there are no payments to approve in connection with the SPMA and we are not asking our stockholders to conduct such vote. At our last annual meeting held on June 13, 2018, our stockholders approved, on a non-binding advisory basis, the compensation of the Company’s named executive officers.
Material U.S. Federal Income Tax Consequences of the Merger Transaction
The following discussion is a summary of the material U.S. federal income tax consequences of the Merger Transaction to U.S. Holders and Non-U.S. Holders (each as defined below) of our common stock whose shares are converted into the right to receive cash and CVRs pursuant to the Merger Transaction and the post-merger ownership and disposition of the CVRs, but it does not purport to be a complete analysis of all potential tax effects. The effects of other U.S. federal tax laws, such as estate and gift tax laws, and any applicable state, local or non-U.S. tax laws are not discussed. This discussion is based on the Internal Revenue Code of 1986, as amended, which we refer to as the “Code”, Treasury regulations promulgated thereunder, judicial decisions, and published rulings and administrative pronouncements of the U.S. Internal Revenue Service, which we refer to as the “IRS”, in each case in effect as of the date hereof.
These authorities may change or be subject to differing interpretations. Any such change or differing interpretation may be applied retroactively in a manner that could adversely affect a U.S. Holder or Non-U.S. Holder. We have not sought and will not seek any rulings from the IRS regarding the matters discussed below. There can be no assurance the IRS or a court will not take a contrary position to that discussed below regarding the U.S. federal income tax consequences of the Merger Transaction and the ownership and disposition of the CVRs.
36

TABLE OF CONTENTS
This discussion is limited to holders who hold our common stock as a “capital asset” within the meaning of Section 1221 of the Code (generally, property held for investment). This discussion does not address all U.S. federal income tax consequences relevant to a holder’s particular circumstances, including the impact of the Medicare contribution tax on net investment income or the alternative minimum tax. In addition, it does not address consequences relevant to holders subject to special rules, including, without limitation:

tax-exempt organizations or governmental organizations;

S-corporations, partnerships or any other entities or arrangements treated as partnerships or pass-through entities for U.S. federal income tax purposes (and investors therein);

banks, insurance companies and other financial institutions;

brokers, dealers or traders in securities;

regulated investment companies or real estate investment trusts;

U.S. expatriates and former citizens or long-term residents of the United States;

persons holding our common stock as part of a hedge, straddle or other risk reduction transaction or as part of a conversion transaction or other integrated investment;

persons deemed to sell our common stock under the constructive sale provisions of the Code;

persons who received our common stock in a compensatory transaction;

U.S. Holders whose “functional currency” is not the U.S. dollar;

“controlled foreign corporations”, “passive foreign investment companies” or corporations that accumulate earnings to avoid U.S. federal income tax;

tax-qualified retirement plans; and

persons who do not vote in favor of the Merger Transaction and who properly demand appraisal of their shares under Delaware law.
If a partnership (including an entity or arrangement, domestic or foreign, treated as a partnership for U.S. federal income tax purposes) is a beneficial owner of our common stock, the tax treatment of a partner in such partnership will generally depend upon the status of the partner, the activities of the partnership and certain determinations made at the partner level. Partnerships holding our common stock and partners therein should consult their tax advisors regarding the U.S. federal income tax consequences of the Merger Transaction and the ownership and disposition of the CVRs. This discussion does not address the Purchaser Group or any of their affiliates.
THIS DISCUSSION IS PROVIDED FOR GENERAL INFORMATION PURPOSES ONLY AND IS NOT TAX ADVICE. HOLDERS SHOULD CONSULT THEIR OWN TAX ADVISORS CONCERNING THE U.S. FEDERAL INCOME TAX CONSEQUENCES RELATING TO THE MERGER TRANSACTION AND THE OWNERSHIP AND DISPOSITION OF THE CVRS IN LIGHT OF THEIR PARTICULAR CIRCUMSTANCES AND ANY CONSEQUENCES ARISING UNDER OTHER U.S. FEDERAL TAX LAWS OR THE LAWS OF ANY STATE, LOCAL OR NON-U.S. TAXING JURISDICTION.
U.S. Holders
For purposes of this discussion, a “U.S. Holder” is a beneficial owner of our common stock that, for U.S. federal income tax purposes, is or is treated as any of the following:

an individual who is a citizen or resident of the United States;

a corporation (including an entity treated as a corporation for U.S. federal income tax purposes) created or organized under the laws of the United States, any state thereof or the District of Columbia;
37

TABLE OF CONTENTS

an estate, the income of which is subject to U.S. federal income taxation regardless of its source; or

a trust (1) that is subject to the primary supervision of a court within the United States and the control of one or more United States persons as defined in Section 7701(a)(30) of the Code; or (2) that has a valid election in effect under applicable Treasury regulations to be treated as a United States person for U.S. federal income tax purposes.
The receipt of cash and the CVRs by a U.S. Holder in exchange for our common stock pursuant to the Merger Transaction will be treated as a taxable transaction for U.S. federal income tax purposes. In general, a U.S. Holder’s gain or loss will be equal to the difference, if any, between (i) the amount of cash received and the fair market value of the CVRs received (measured at the effective time of the Merger Transaction), and (ii) such U.S. Holder’s adjusted tax basis in the shares surrendered pursuant to the Merger Transaction. Such gain or loss will be a capital gain or loss, and will be a long-term capital gain or loss if such U.S. Holder’s holding period in such shares is more than one year at the time of the Merger Transaction. A preferential tax rate generally will apply to long-term capital gains recognized by certain non-corporate U.S. Holders. The deductibility of capital losses is subject to limitations.
If a U.S. Holder acquired different blocks of our common stock at different times or different prices, such U.S. Holder must determine its tax basis, holding period and gain or loss separately with respect to each block of our common stock. The initial tax basis of the CVRs received in the Merger Transaction by a U.S. Holder will generally be equal to their fair market value and a U.S. Holder’s holding period in the CVRs will begin the day after the effective time of the Merger Transaction.
There is no legal authority directly addressing the U.S. federal income tax treatment of CVRs. Subject to the discussion of Section 483 of the Code, which we refer to as the “Section 483 rules,” (A) a payment with respect to a CVR is likely to first be treated as a non-taxable return of a U.S. Holder’s adjusted basis in such CVR, with amounts in excess of such adjusted basis potentially treated as one of the following: (i) a payment with respect to the sale of a capital asset, (ii) income taxed at ordinary rates, or (iii) dividends; and (B) if total payments with respect to a CVR are less than a U.S. Holder’s basis in a CVR, such U.S. Holder is likely entitled to a loss to the extent of such deficiency, although it is unclear whether any such loss should be treated as capital or ordinary.
Although not entirely clear, it is possible that a portion of a payment under a CVR could be characterized as “interest” under the Section 483 rules and taxable as ordinary income to a U.S. Holder. If applicable, the “interest” amount will equal the excess of the amount received over its present value at the consummation of the Merger Transaction, calculated using the applicable federal rate as the discount rate. The U.S. Holder of a CVR must include any such interest under the Section 483 rules in its taxable income using such U.S. Holder’s regular method of accounting. The portion of the CVR payment not treated as interest under the Section 483 rules, less the U.S. Holder’s basis in the CVR, would generally be treated as capital gain, and a U.S. Holder would generally be entitled to a loss (which would likely be a capital loss) if payments received under the CVRs were less than such U.S. Holder’s adjusted tax basis in such CVRs.
There is no authority directly on point addressing how contingent value rights with characteristics similar to the CVRs should be treated for U.S. federal income tax purposes. It is possible that the IRS might successfully assert that payments with respect to, or sales or other dispositions of, the CVRs should be treated other than described above. U.S. Holders are urged to consult their tax advisors with respect to the proper characterization of the receipt of the CVRs and any payments made thereon.
Non-U.S. Holders
For purposes of this discussion, a “Non-U.S. Holder” is a beneficial owner of our common stock that is not a U.S. Holder or a partnership for U.S. federal income tax purposes. Except as discussed below, payments of cash and CVRs made to a Non-U.S. Holder in exchange for shares of our common stock pursuant to the Merger Transaction generally will not be subject to U.S. federal income tax unless:

The gain, if any, on such shares is effectively connected with a trade or business of the Non-U.S. Holder in the United States (and, if required by an applicable income tax treaty, is attributable to the Non-U.S. Holder’s permanent establishment in the United States); or
38

TABLE OF CONTENTS

The Non-U.S. Holder is an individual who is present in the United States for 183 days or more in the taxable year of the exchange of shares of our common stock for cash pursuant to the Merger Transaction and certain other conditions are met.
A Non-U.S. Holder described in the first bullet point immediately above will be subject to regular U.S. federal income tax on any gain realized as if the Non-U.S. Holder were a U.S. Holder, subject to any applicable income tax treaty providing otherwise. If such Non-U.S. Holder is a foreign corporation for U.S. federal income tax purposes, then any gain described in the first bullet above may also be subject to an additional “branch profits tax” at a 30% rate (or a lower treaty rate). A Non-U.S. Holder described in the second bullet point immediately above will be subject to tax at a rate of 30% (or a lower treaty rate) on any capital gain realized, which may be offset by certain U.S.-source capital losses recognized in the same taxable year, even though the individual is not considered a resident of the United States.
Payments made to a Non-U.S. Holder under the CVRs treated as interest could potentially be subject to U.S. withholding tax, and the paying agent may withhold on such payments at a rate of 30% unless the Non-U.S. Holder properly certifies that the interest is effectively connected with the Non-U.S. Holder’s trade or business in the United States or that the Non-U.S. Holder is eligible for the benefits of a U.S. income tax treaty that exempts or otherwise reduces the rate of any such U.S. withholding tax. Although there is no authority directly on point, a Non-U.S. Holder may also be entitled to an exemption from U.S. withholding tax under the “portfolio interest” rules if it complies with certain identification requirements (including delivery of a statement, signed by the Non-U.S. Holder under penalties of perjury, certifying that such Non-U.S. Holder is not a United States person and providing the name and address of such Non-U.S. Holder, with such statement generally made on IRS Form W-8BEN or IRS Form W-8BEN-E), and meets certain other requirements.
Information Reporting and Backup Withholding
Payments made in exchange for shares of our common stock or in respect of the CVRs generally will be subject to information reporting unless the holder is an “exempt recipient” and may also be subject to backup withholding at a rate of 24%. To avoid backup withholding, U.S. Holders that do not otherwise establish an exemption should complete and return Internal Revenue Service Form W-9, certifying under penalty of perjury that such U.S. Holder is a U.S. person, the taxpayer identification number provided is correct and such U.S. Holder is not subject to backup withholding. A Non-U.S. Holder that provides the applicable withholding agent with the appropriate Internal Revenue Service Form W-8 will generally establish an exemption from backup withholding. Amounts withheld under the backup withholding rules are not additional taxes and may be refunded or credited against a holder’s U.S. federal income tax liability, provided that the holder files a U.S. federal income tax return with the Internal Revenue Service. You are urged to consult your tax advisor with respect to the application of U.S. federal income tax laws to your particular circumstances as well as any tax consequences arising under the U.S. federal estate or gift tax rules, or under any state, local or foreign tax laws.
FATCA Regime
The Foreign Account Tax Compliance Act (“FATCA”) tax regime requires tax reporting and compliance with respect to direct and indirect ownership by United States persons of assets through foreign accounts. Under FATCA, U.S. withholding tax will apply on interest payments made to certain foreign entities if certain disclosure requirements related to U.S. accounts or ownership are not satisfied. It is unclear whether and to what extent FATCA may apply to potential payments made to Non-U.S. Holders pursuant to the CVRs. Prospective investors should consult their own tax advisors regarding FATCA to their particular situation.
Regulatory Approvals Required for the Merger Transaction
Under the HSR Act, certain merger transactions may not be consummated unless various information and documentary materials have been furnished to the Antitrust Division of the Department of Justice (“Antitrust Division”) and the Federal Trade Commission (the “FTC”) and certain waiting period requirements have been satisfied. The requirements of the HSR Act apply to the Merger Transaction, and the Merger Transaction is conditioned on expiration or termination of the applicable waiting period under
39

TABLE OF CONTENTS
the HSR Act. Under the terms of the SPMA, the Merger Transaction cannot be completed until the waiting period (and any extension thereof) applicable to the Merger Transaction has expired or been terminated. To complete the Merger Transaction, the parties must make filings with and obtain authorizations, approvals or consents from certain antitrust authorities.
The FTC and the Antitrust Division will consider the legality under the antitrust laws of the Merger Transaction, and the transactions contemplated by the SPMA. At any time before consummation of the Merger Transaction, if the Antitrust Division or the FTC believes that the Merger Transaction would violate the U.S. federal antitrust laws by substantially lessening competition in any line of commerce affecting U.S. consumers, the FTC and the Antitrust Division have the authority to challenge the Merger Transaction by seeking a federal court order enjoining the Merger Transaction or, if the Merger Transaction has already been consummated, requiring disposition of the Avenue ordinary shares or the divestiture of substantial assets of Parent, Avenue or any of their respective subsidiaries or affiliates. U.S. state attorneys general and private persons may also bring legal action under the antitrust laws seeking similar relief or seeking conditions to the completion of the Merger Transaction. While Avenue believes that the consummation of the Merger Transaction will not violate any antitrust laws, there can be no assurance that a challenge to the Merger Transaction on antitrust grounds will not be made or, if a challenge is made, what the result will be. If any such action is threatened or commenced by the FTC, the Antitrust Division or any state or any other person, Parent may not be obligated to consummate the Merger Transaction.
Antitrust Approvals.   After the First Stage Closing and before the Second Stage Closing, the Company and Parent will use their reasonable best efforts to obtain all authorizations, consents, orders, actions, and approvals required to consummate the Merger Transaction and the transactions contemplated by the SPMA. The Merger Transaction cannot be completed until all applicable waiting periods under the HSR Act have expired or been terminated following the submission of complete filings with the Antitrust Division and FTC. Under the provisions of the HSR Act applicable to the Merger Transaction, the waiting period will expire at 11:59 p.m., Eastern Time, 30 calendar days following the filing of a Premerger Notification and Report Form by both the Parent and the Company with the FTC and Antitrust Division, unless such 30th day is a Saturday, Sunday or other legal public holiday, in which case the waiting period will expire at 11:59 p.m., Eastern Time, on the next business day. Before such time, however, either the FTC or Antitrust Division may terminate the waiting period or extend the waiting period by issuing a Request for Additional Information (a “Second Request”) to Parent and the Company. If a Second Request is made, the waiting period will expire at 11:59 p.m. Eastern Time, on the 30th calendar day after Parent or its affiliate certifies substantial compliance with such request, unless again otherwise extended by agreement or court order.
The consummation of the Merger Transaction is not conditioned on any antitrust-law-related regulatory filings in the United States or in any other jurisdiction, other than those described above.
Delisting and Deregistration of Common Stock
If the Merger Transaction is completed, Avenue will be a privately owned company and there will be no public market for our common stock. Upon completion of the Merger Transaction, our common stock will be delisted from Nasdaq. In addition, the registration of our common stock under Section 12 of the Exchange Act will be terminated and we will no longer file reports with the SEC.

Anticipated Accounting Treatment of the Merger Transaction

Rights of Appraisal
If the Merger Transaction is completed, the Company’s stockholders will be entitled to appraisal rights under Section 262 of the DGCL, provided that they comply with the conditions set forth in that statute.
Pursuant to Section 262 of the DGCL, if you do not wish to accept the Merger Consideration provided for in the SPMA, you have the right to seek appraisal of your shares of our common stock and to receive payment in cash for the fair value of your shares of our common stock, exclusive of any element of value arising from the accomplishment or expectation of the Merger Transaction, as determined by the Delaware Court of Chancery, together with interest, if any, to be paid upon the amount determined to be fair value. The “fair value” of your shares of our common stock as determined by the Delaware Court of Chancery may be less than, equal to or more than the estimated $13.92 per share in cash that you may otherwise be entitled to receive as part of the Merger Consideration under the terms of the SPMA, in addition to contingent cash payments pursuant to the CVR Agreement upon the achievement of certain milestones, without interest and less any applicable withholding taxes. These rights are known as “appraisal rights.” The Company’s stockholders who do not vote in favor of the SPMA Proposal and who properly demand appraisal for their shares in compliance with the provisions of Section 262 of the DGCL will be entitled to appraisal rights. Strict compliance with the statutory procedures set forth in Section 262 of the DGCL is required. Failure to follow precisely any of the statutory requirements will result in the loss of your appraisal rights.
This section is intended only as a brief summary of certain provisions of the statutory procedures that a stockholder must follow under the DGCL in order to seek and perfect appraisal rights. This summary, however, is not a complete statement of all applicable requirements and the law pertaining to appraisal rights under the DGCL, and is qualified in its entirety by reference to Section 262 of the DGCL, the full text of which appears in Annex C to this proxy statement. The following summary does not constitute any legal or other advice, nor does it constitute a recommendation that stockholders exercise their appraisal rights under Section 262 of the DGCL.
Pursuant to Section 262 of the DGCL, when a merger agreement will be submitted for adoption at a meeting of stockholders, the Company must notify the stockholders who were stockholders of record on the record date for notice of such meeting, not less than 20 days before the meeting to vote on the merger, that appraisal rights will be available. A copy of Section 262 of the DGCL must be included with the notice.
This proxy statement constitutes the Company’s notice to our stockholders that appraisal rights are available in connection with the Merger Transaction, and the full text of Section 262 of the DGCL is
41

TABLE OF CONTENTS
attached to this proxy statement as Annex C and incorporated herein by reference, in compliance with the requirements of Section 262 of the DGCL. If you wish to exercise your appraisal rights, you should carefully review the text of Section 262 of the DGCL contained in Annex C. Failure to comply timely and properly with the requirements of Section 262 of the DGCL will result in the loss of your appraisal rights. Moreover, because of the complexity of the procedures for exercising the right to seek appraisal of shares of our common stock, the Company believes that a stockholder considering the exercise of such rights should seek the advice of legal counsel.
If you wish to demand appraisal of your shares of our common stock, you must satisfy each of the following conditions: (i) you must deliver to the Company a written demand for appraisal of your shares of our common stock before the vote is taken to approve the SPMA Proposal; (ii) the written demand must reasonably inform us of the identity of the holder of record of shares of our common stock who intends to demand appraisal of his, her or its shares of our common stock; and (iii) you must not vote or submit a proxy in favor of the SPMA Proposal.
If you fail to comply with any of these conditions and the Merger Transaction is completed, you will be entitled to receive payment for your shares of our common stock as provided in the SPMA, in addition to receiving contingent cash payments pursuant to the CVR Agreement upon the achievement of certain milestones, but you will not have appraisal rights with respect to your shares of our common stock. A holder of shares of our common stock wishing to exercise appraisal rights must hold of record the shares of our common stock on the date the written demand for appraisal is made and must continue to hold the shares of our common stock of record through the effective time of the Merger Transaction. A proxy that is submitted and does not contain voting instructions will, unless revoked, be voted “FOR” the SPMA Proposal, and it will result in the loss of the stockholder’s right of appraisal and will nullify any previously delivered written demand for appraisal. Therefore, a stockholder who submits a proxy and who wishes to exercise appraisal rights must either submit a proxy containing instructions to vote “AGAINST” the SPMA Proposal or “ABSTAIN” from voting on the SPMA Proposal. Voting against or failing to vote for the SPMA Proposal by itself does not constitute a demand for appraisal within the meaning of Section 262 of the DGCL. The written demand for appraisal must be in addition to and separate from any proxy or vote on the SPMA Proposal.
All demands for appraisal should be addressed to the Company’s legal counsel at Alston & Bird LLP, Attention: Matthew Mamak, 90 Park Avenue, 12th Floor, New York, New York 10016 and must be delivered to the Company before the vote is taken to approve the SPMA Proposal at the special meeting, and must be executed by, or on behalf of, the record holder of the shares of our common stock. The demand will be sufficient if it reasonably informs the Company of the identity of the stockholder and the intention of the stockholder to demand appraisal of the “fair value” of his, her or its shares of our common stock. A stockholder’s failure to deliver to the Company the written demand for appraisal prior to the taking of the vote on the SPMA Proposal at the special meeting of stockholders will result in the loss of appraisal rights.
Only a holder of record of shares of our common stock is entitled to demand an appraisal of the shares registered in that holder’s name. Accordingly, to be effective, a demand for appraisal by a holder of our common stock must be made by, or on behalf of, the record stockholder. The demand should set forth, fully and correctly, the record stockholder’s name as it appears on the stockholder’s stock certificate(s) or in the transfer agent’s records, and in the case of uncertificated shares, should specify the stockholder’s mailing address and the number of shares registered in the stockholder’s name. The demand must state that the person intends thereby to demand appraisal of the stockholder’s shares in connection with the Merger Transaction. The demand cannot be made by the beneficial owner if he or she does not also hold the shares of our common stock of record. The beneficial holder must, in such cases, have the registered owner, such as a bank, brokerage firm or other nominee, submit the required demand in respect of those shares of our common stock. If you hold your shares of our common stock through a bank, brokerage firm or other nominee and you wish to exercise your appraisal rights, you should consult with your bank, brokerage firm or the other nominee to determine the appropriate procedures for the making of a demand for appraisal by the nominee and obtaining notice of the effective date of the Merger Transaction.
If shares of our common stock are owned of record in a fiduciary capacity, such as by a trustee, guardian or custodian, execution of a demand for appraisal must be made in that capacity. If the shares of

our common stock are owned of record by more than one person, as in a joint tenancy or tenancy in common, the demand must be executed by or for all joint owners. An authorized agent, including an authorized agent for two or more joint owners, may execute the demand for appraisal for a stockholder of record; however, the agent must identify the record owner or owners and expressly disclose the fact that, in executing the demand, he or she is acting as agent for the record owner or owners. A record owner, such as a bank, brokerage firm or other nominee, who holds shares of our common stock as a nominee for others, may exercise his or her right of appraisal with respect to shares of our common stock held for one or more beneficial owners, while not exercising this right for other beneficial owners. In that case, the written demand should state the number of shares of our common stock as to which appraisal is sought. Where no number of shares of our common stock is expressly mentioned, the demand will be presumed to cover all shares of our common stock held in the name of the record owner. If a stockholder holds shares of our common stock through a broker who in turn holds the shares through a central securities depository nominee such as Cede & Co., a demand for appraisal of such shares must be made by or on behalf of the depository nominee and must identify the depository nominee as record owner.
Within 10 days after the effective time of the Merger Transaction, the surviving corporation in the Merger Transaction must give notice of the date that the Merger Transaction became effective to each of the Company’s record stockholders who has complied with Section 262 of the DGCL and who did not vote in favor of the SPMA Proposal. At any time within 60 days after the effective time of the Merger Transaction, any stockholder who has not commenced an appraisal proceeding or joined a proceeding as a named party may withdraw the stockholder’s demand and accept the Merger Consideration specified by the SPMA for that holder’s shares of our common stock by delivering to the surviving corporation a written withdrawal of the demand for appraisal. However, any such attempt to withdraw the demand made more than 60 days after the effective time of the Merger Transaction will require written approval of the surviving corporation. No appraisal proceeding in the Delaware Court of Chancery will be dismissed as to any stockholder without the approval of the Delaware Court of Chancery, with such approval conditioned upon such terms as the Delaware Court of Chancery deems just. If the surviving corporation does not approve a request to withdraw a demand for appraisal when that approval is required, or, except with respect to any stockholder who withdraws such stockholder’s right to appraisal in accordance with the second sentence of this paragraph, if the Delaware Court of Chancery does not approve the dismissal of an appraisal proceeding, the stockholder will be entitled to receive only the appraised value of his, her or its shares of our common stock determined in any such appraisal proceeding, which value may be less than, equal to or more than the Merger Consideration offered pursuant to the SPMA.
Within 120 days after the effective time of the Merger Transaction, but not thereafter, either the surviving corporation or any stockholder who has complied with the requirements of Section 262 of the DGCL and is entitled to appraisal rights under Section 262 of the DGCL may commence an appraisal proceeding by filing a petition in the Delaware Court of Chancery demanding a determination of the fair value of the shares of our common stock held by all such stockholders. Upon the filing of the petition by a stockholder, service of a copy of such petition shall be made upon the surviving corporation. The surviving corporation has no obligation to file such a petition, has no present intention to file a petition and holders should not assume that the surviving corporation will file a petition. Accordingly, it is the obligation of the holders of our common stock to initiate all necessary petitions to perfect their appraisal rights in respect of shares of our common stock within the time prescribed in Section 262 of the DGCL and the failure of a stockholder to file such a petition within the period specified in Section 262 of the DGCL could nullify the stockholder’s previous written demand for appraisal. In addition, within 120 days after the effective time of the Merger Transaction, any stockholder who has properly complied with the requirements of Section 262 of the DGCL and who did not vote in favor of the SPMA Proposal will be entitled to receive from the surviving corporation, upon written request, a statement setting forth the aggregate number of shares of our common stock not voted in favor of the SPMA Proposal and with respect to which demands for appraisal have been received and the aggregate number of holders of such shares. The statement must be mailed within 10 days after such written request has been received by the surviving corporation or within 10 days after the expiration of the period for delivery of demands for appraisal, whichever is later. A person who is the beneficial owner of shares of our common stock held either in a voting trust or by a nominee on behalf of such person may, in such person’s own name, file a petition for appraisal or request from the surviving corporation such statement.

TABLE OF CONTENTS
If a petition for appraisal is duly filed by a stockholder and a copy of the petition is delivered to the surviving corporation, then the surviving corporation will be obligated, within 20 days after receiving service of a copy of the petition, to file with the Delaware Register in Chancery a duly verified list containing the names and addresses of all stockholders who have demanded an appraisal of their shares of our common stock and with whom agreements as to the value of their shares of our common stock have not been reached. After notice to stockholders who have demanded appraisal from the Register in Chancery, if such notice is ordered by the Delaware Court of Chancery, the Delaware Court of Chancery will conduct a hearing upon the petition and determine those stockholders who have complied with Section 262 of the DGCL and who have become entitled to the appraisal rights provided by Section 262 of the DGCL. The Delaware Court of Chancery may require stockholders who have demanded payment for their shares of our common stock to submit their stock certificates to the Register in Chancery for notation of the pendency of the appraisal proceedings; if any stockholder fails to comply with that direction, the Delaware Court of Chancery may dismiss the proceedings as to that stockholder.
After determination of the stockholders entitled to appraisal of their shares of our common stock, the Delaware Court of Chancery will appraise the shares of our common stock, determining their fair value as of the effective time of the Merger Transaction after taking into account all relevant factors exclusive of any element of value arising from the accomplishment or expectation of the Merger Transaction, together with interest, if any, to be paid upon the amount determined to be the fair value. When the fair value has been determined, the Delaware Court of Chancery will direct the payment of such value upon surrender by those stockholders of the certificates representing their shares of our common stock. Unless the Delaware Court of Chancery in its discretion determines otherwise for good cause shown, interest from the effective date of the Merger Transaction through the date of payment of the judgment shall be compounded quarterly and shall accrue at 5% over the Federal Reserve discount rate (including any surcharge) as established from time to time during the period between the effective time of the Merger Transaction and the date of payment of the judgment. At any time before the entry of judgment in the proceedings, the surviving corporation may pay to each stockholder entitled to appraisal an amount in cash, in which case interest shall accrue thereafter only upon the sum of  (1) the difference, if any, between the amount paid and the fair value of the shares as determined by the Delaware Court of Chancery, and (2) interest theretofore accrued, unless paid at that time.
You should be aware that an investment banking opinion as to the fairness from a financial point of view of the consideration to be received in a sale transaction, such as the Merger Transaction, is not an opinion as to, and does not in any way address, fair value under Section 262 of the DGCL. Although we believe that the Merger Consideration is fair, no representation is made as to the outcome of the appraisal of fair value as determined by the Delaware Court of Chancery and stockholders should recognize that such an appraisal could result in a determination of a value that may be less than, equal to or more than the Merger Consideration. Moreover, we do not anticipate offering more than the Merger Consideration to any stockholder exercising appraisal rights and reserve the right to assert, in any appraisal proceeding, that, for purposes of Section 262 of the DGCL, the “fair value” of a share of our common stock is less than the Merger Consideration. In determining “fair value”, the Delaware Court of Chancery is required to take into account all relevant factors. In Weinberger v. UOP, Inc., the Delaware Supreme Court discussed the factors that could be considered in determining fair value in an appraisal proceeding, stating that “proof of value by any techniques or methods which are generally considered acceptable in the financial community and otherwise admissible in court” should be considered and that “[f]air price obviously requires consideration of all relevant factors involving the value of a company.” The Delaware Supreme Court has stated that in making this determination of fair value, the court must consider market value, asset value, dividends, earnings prospects, the nature of the enterprise and any other facts which could be ascertained as of the date of the Merger Transaction which throw any light on future prospects of the merged corporation. Section 262 of the DGCL provides that fair value is to be “exclusive of any element of value arising from the accomplishment or expectation of the merger”. In Cede & Co. v. Technicolor, Inc., the Delaware Supreme Court stated that such exclusion is a “narrow exclusion [that] does not encompass known elements of value”, but which rather applies only to the speculative elements of value arising from such accomplishment or expectation. In Weinberger, the Delaware Supreme Court also stated that “elements of future value, including the nature of the enterprise, which are known or susceptible of proof as of the date of the merger and not the product of speculation, may be considered”.

TABLE OF CONTENTS
Costs of the appraisal proceeding (which do not include attorneys’ fees or the fees and expenses of experts) may be determined by the Delaware Court of Chancery and imposed upon the surviving corporation and the stockholders participating in the appraisal proceeding by the Delaware Court of Chancery, as it deems equitable in the circumstances. Upon the application of a stockholder, the Delaware Court of Chancery may order all or a portion of the expenses incurred by any stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorneys’ fees and the fees and expenses of experts used in the appraisal proceeding, to be charged pro rata against the value of all shares of our common stock entitled to appraisal. Any stockholder who demanded appraisal rights will not, after the effective time of the Merger Transaction, be entitled to vote shares of our common stock subject to that demand for any purpose or to receive payments of dividends or any other distribution with respect to those shares of our common stock, other than with respect to payment as of a record date prior to the effective time of the Merger Transaction. If no petition for appraisal is filed within 120 days after the effective time of the Merger Transaction, or if the stockholder otherwise fails to perfect, successfully withdraws or loses such holder’s right to appraisal, then the right of that stockholder to appraisal will cease and each of the shares of our common stock owned by that stockholder will be deemed to have been converted at the effective time of the Merger Transaction into the right to receive approximately $13.92 per share in cash (without interest) pursuant to the SPMA, in addition to certain milestone payments pursuant to the CVR Agreement. Inasmuch as the Company has no obligation to file such a petition, and the Company has no present intention to do so, any holder of shares of our common stock who desires such a petition to be filed is advised to file it on a timely basis. A stockholder will fail to perfect or effectively lose the right to appraisal if no petition for appraisal is filed within 120 days after the effective date of the Merger Transaction. In addition, as indicated above, a stockholder may withdraw his, her or its demand for appraisal in accordance with Section 262 of the DGCL and accept the Merger Consideration offered pursuant to the SPMA.
Failure to comply strictly with all of the procedures set forth in Section 262 of the DGCL will result in the loss of a stockholder’s statutory appraisal rights.
In view of the complexity of Section 262 of the DGCL, the Company’s stockholders who may wish to pursue appraisal rights should consult their own legal and financial advisors.

TABLE OF CONTENTS
THE SPECIAL MEETING
We are furnishing this proxy statement to Avenue stockholders as part of the solicitation of proxies by the Board for use at the special meeting and at any adjournment or postponement thereof.
Date, Time and Place of the Special Meeting
The special meeting will be held on February 6, 2019 at 10:00 a.m., Eastern Time, at the offices of our legal counsel, Alston & Bird LLP, located at 90 Park Avenue, New York, New York 10016, or at any adjournment or postponement thereof.
Purpose of the Special Meeting
The SPMA provides that at the effective time of the Merger Transaction, Merger Sub will merge with and into the Company, with the Company continuing as the surviving corporation and a wholly-owned subsidiary of Parent. At the special meeting, you will be asked to consider and vote upon the following proposals:

the proposal to approve and adopt the SPMA and the Ancillary Agreements, and the consummation of the transactions contemplated thereby, including the Stock Purchase Transaction and the Merger Transaction, and the appointment of a rights agent (the “Rights Agent”) in connection with the CVR Agreement, which we refer to as the “SPMA Proposal”, as described in the section entitled “Proposal 1: SPMA Proposal” beginning on page 54 of this proxy statement;

the proposal to approve the adjournment of the special meeting from time to time, if necessary or appropriate, including to solicit additional proxies if there are insufficient votes at the time of the special meeting to adopt the SPMA or in the absence of a quorum, which we refer to as the “Adjournment Proposal”, as described in the section entitled “Proposal 2: Adjournment Proposal” beginning on page 55 of this proxy statement; and

to transact any other business that may properly come before the special meeting, or any adjournment or postponement of the special meeting, by or at the direction of the Board.
The Board unanimously recommends that you vote “FOR” each of the above proposals.
Our stockholders must approve the SPMA Proposal in order for the Stock Purchase Transaction and the Merger Transaction to occur. If the Company stockholder approval is not obtained to approve the SPMA Proposal, then the Stock Purchase Transaction and the Merger Transaction will not occur. If the Company stockholder approval is obtained, but the Non-Affiliate Stockholder Approval (as defined below) of the SPMA Proposal is not obtained, Parent may terminate the SPMA prior to the consummation of the Stock Purchase Transaction. For further information see the section entitled “The Special Meeting — Vote Required” beginning on page 49.
Record Date and Quorum
The Board has fixed the close of business on December 13, 2018 as the record date for determination of stockholders entitled to receive notice of, and to vote at, the special meeting, and any adjournments or postponements thereof. Only holders of record of our common stock as of the close of business on the record date are entitled to receive notice of, and to vote at (in person or by proxy), the special meeting and at any adjournment or postponement thereof.
As of the close of business on the record date, there were 10,667,714 shares of our common stock outstanding. Each holder of our common stock is entitled to cast one vote per such share on each matter properly brought before the special meeting for each share of our common stock that such holder owned as of the record date.
The presence at the special meeting, in person or represented by proxy, of the holders of a majority of the shares of our common stock issued and outstanding and entitled to vote at the special meeting constitutes a quorum for the transaction of business at the special meeting. Once a share is represented at
48

TABLE OF CONTENTS
the special meeting, it will be counted for the purpose of determining a quorum at the special meeting. Shares of our common stock represented at the special meeting but not voted, including shares of our common stock for which proxies have been received but for which stockholders have abstained, will be treated as present at the special meeting for purposes of determining the presence or absence of a quorum for the transaction of all business. Broker non-votes are deemed to be “present” at the meeting for quorum purposes. Your vote is very important, regardless of the number of shares of our common stock you own. Because stockholders cannot take any action at the meeting unless a majority of our common stock issued and outstanding and entitled to vote thereat is represented, it is important that you attend the meeting in person or are represented by proxy at the meeting.
In the event that a quorum is not present at the special meeting, we expect to adjourn or postpone the special meeting until we solicit enough proxies to obtain a quorum.
Attendance
Only stockholders of record, their duly appointed proxy holders and our guests may attend the special meeting. If you plan to attend the special meeting in person, please mark the designated box on the enclosed proxy card. Alternatively, if you utilize the Internet voting system, please indicate your plans to attend the special meeting when prompted to do so by the system. If you are a stockholder of record, you should bring the bottom half of the enclosed proxy card as your admission card and present the card upon entering the special meeting. If you are planning to attend the special meeting and your shares are held in street name (by a bank or broker, for example), you should ask the record owner for a legal proxy or bring your most recent account statement to the special meeting so that we can verify your ownership of Avenue stock. Please note, however, that if your shares are held in street name and you do not bring a legal proxy from the record owner, you will be able to attend the special meeting, but you will not be able to vote at the special meeting. If you are the representative of a corporate or institutional stockholder, you must present valid photo identification along with proof that you are the representative of such stockholder. Please note that cameras, recording devices and other electronic devices will not be permitted at the special meeting.
Vote Required
SPMA Proposal
Approval of the SPMA Proposal requires the affirmative vote of stockholders holding a majority of the aggregate voting power of the shares outstanding and entitled to vote on such proposal, which we refer to as the “Company stockholder approval”. However, in addition to the Company stockholder approval, which is required under Delaware law, under the SPMA Parent’s obligation to consummate the Stock Purchase Transaction is subject to approval of the SPMA proposal by a majority of our common stock held by stockholders who are not affiliates of the Company, which we refer to as the “Non-Affiliate Stockholder Approval”. For further information see the section entitled “The SPMA — Conditions to Completion of the Stock Purchase Transaction and the Merger Transaction” beginning on page 69.
Adjournment Proposal
Approval of the Adjournment Proposal requires the affirmative vote of stockholders holding a majority of the aggregate voting power of the shares outstanding and entitled to vote present, in person or by proxy, on such proposal at the special meeting.
Record Ownership; Beneficial Ownership
If your shares of our common stock are registered directly in your name with our transfer agent, VStock Transfer LLC, then you are considered, with respect to those shares of our common stock, the “stockholder of record”. This proxy statement and proxy card have been sent directly to you by the Company. As the stockholder of record, you have the right to vote in person at the meeting or to grant your voting rights directly to the Company or to a third party by a proxy duly executed or transmitted in a manner in accordance with applicable law. To gain admittance, please bring either (i) the bottom half of the enclosed proxy card as your admission card and present the card upon entering the special meeting or, (ii) if your shares are held in street name (by a bank or broker, for example), you should ask the record owner for
49

TABLE OF CONTENTS
a legal proxy or bring your most recent account statement to the special meeting so that we can verify your ownership of the Company’s stock. For more information, please follow the instructions under “The Special Meeting — Attendance” beginning on page 49 of this proxy statement.
If your shares of our common stock are held through a bank, brokerage firm or other nominee, you are considered the “beneficial owner” of those shares. In that case, this proxy statement has been forwarded to you by your bank, brokerage firm or other nominee who is considered, with respect to those shares of our common stock, the stockholder of record. As the beneficial owner, you have the right to direct your bank, brokerage firm or other nominee how to vote your shares of our common stock by following their instructions for voting. Your bank, brokerage firm or other nominee should send you, as the beneficial owner, a package describing the procedure for voting your shares.
Effects of Failing to Vote and Abstentions; Broker Non-Votes
For each of the SPMA Proposal and the Adjournment Proposal, you may vote “FOR”, “AGAINST” or “ABSTAIN.
If you fail to submit a proxy or to vote in person at the special meeting, then your shares will not be included in the calculation of the number of shares of our common stock represented at the special meeting for purposes of determining whether a quorum has been achieved. Failing to vote either in person or by proxy at the special meeting will have the same effect as a vote “AGAINST” the SPMA Proposal. Such failure to vote (assuming a quorum is present for the special meeting) will have no effect on the Adjournment Proposal.
An abstention occurs when a stockholder attends a meeting, either in person or by proxy, but abstains from voting on one or more proposals. Abstaining stockholders will be considered present and entitled to vote and the special meeting, and those shares will count towards determining whether a quorum has been achieved. Abstaining from voting on any proposal at the special meeting will have the same effect as a vote “AGAINST” such proposal.
Under applicable rules, brokers, banks or other nominees who hold shares of our common stock in street name for a beneficial owner of those shares typically have the authority to vote in their discretion on “routine” proposals when they have not received instructions from beneficial owners. However, brokers, banks or other nominees are not allowed to exercise their voting discretion with respect to the approval of matters that are “non-routine” without specific instructions from the beneficial owner. All proposals to be voted on by you at the special meeting are “non-routine” matters, and therefore brokers do not have discretionary authority to vote on any of the proposals. Broker non-votes occur when a broker, bank or other nominee is not instructed by the beneficial owner of shares to vote on a particular proposal for which the broker does not have discretionary voting power. Shares that are subject to broker non-votes are considered not entitled to vote, and therefore will not count toward determining whether or not a quorum is present at the meeting and will be ignored for purposes of determining the outcome of any vote on the SPMA Proposal or the Adjournment Proposal. However, if you do not instruct your bank, brokerage firm or other nominee to vote your shares of our common stock, your shares of our common stock will not be voted, and as broker non-votes, the effect will be the same as a vote “AGAINST” approval of the SPMA Proposal.
Voting
This proxy statement is accompanied by a proxy card with instructions for submitting voting instructions. If you are a stockholder of record and your shares are registered directly in your name, you may have your shares of our common stock voted on matters presented at the special meeting in any of the following ways:

In Person.   You may attend the special meeting and cast your vote there. To gain admittance, please bring either (i) the bottom half of the enclosed proxy card as your admission card and present the card upon entering the special meeting or, (ii) if your shares are held in street name (by a bank or broker, for example), you should ask the record owner for a legal proxy or bring your most recent account statement to the special meeting so that we can verify your ownership of the Company’s stock. Even if you plan to attend the meeting, it is desirable that you vote in advance of the meeting.

Any stockholder of record entitled to vote at the special meeting may submit a proxy by telephone, over the Internet or by returning the enclosed proxy card in the accompanying postage-paid reply envelope, or may vote in person by appearing at the special meeting.

TABLE OF CONTENTS
THE SPMA
This section describes the material terms of the SPMA. The description of the SPMA in this section and elsewhere in this proxy statement is qualified in its entirety by reference to the complete text of the SPMA, a copy of which is attached as Annex A and is incorporated by reference into this proxy statement. This summary does not purport to be complete and may not contain all of the information about the SPMA that is important to you. We encourage you to read the SPMA carefully and in its entirety.
Explanatory Note Regarding the SPMA
The SPMA, a copy of which is attached as Annex A, and this summary of its terms are included in this proxy statement to provide you with information regarding its terms. Factual disclosures about the Company contained in this proxy statement or in the Company’s public reports filed with the SEC may supplement, update or modify the factual disclosures about the Company contained in the SPMA. The representations, warranties and covenants made in the SPMA by the Company, Parent and Merger Sub were made solely to the parties to, and solely for the purposes of, the SPMA and as of specific dates and were qualified and subject to important limitations agreed to by the Company, Parent and Merger Sub in connection with negotiating the terms of the SPMA. In particular, in your review of the representations and warranties contained in the SPMA and described in this summary, it is important to bear in mind that the representations and warranties were negotiated with the principal purposes of establishing the circumstances in which a party to the SPMA may have the right not to consummate the Stock Purchase Transaction and the Merger Transaction if the representations and warranties of the other party prove to be untrue due to a change in circumstance or otherwise, and allocating risk between the parties to the SPMA, rather than establishing matters as facts. The representations and warranties may also be subject to a contractual standard of materiality different from those generally applicable to stockholders and reports and documents filed with the SEC. Moreover, information concerning the subject matter of the representations and warranties may have changed since the date of the SPMA. Investors should not rely on the representations, warranties and covenants or any description thereof as characterizations of the actual state of facts of the Company, Parent, Merger Sub or any of their respective subsidiaries or affiliates.
Additional information about the Company may be found elsewhere in this document and the Company’s other public filings. See the section entitled “Where You Can Find Additional Information” beginning on page 87 of this proxy statement.
Structure of the SPMA
The SPMA provides for the acquisition of the Company by Parent, through a two-stage transaction. The first stage will be the consummation of the Stock Purchase Transaction. The second stage will be the consummation of the Merger Transaction.
The Stock Purchase Transaction
At the First Stage Closing, subject to prior satisfaction of the First Stage Closing Conditions, Parent will acquire common stock representing 33.3% of the fully diluted capitalization of the Company for $35 million (currently expected to be 5,833,333 shares at $6.00 per share). The First Stage Closing shall take place, and the Stock Purchase Transaction shall become effective, no later than five business days after the satisfaction or waiver of the First Stage Closing Conditions, or at such later time as may be agreed by Parent and the Company in writing.
The Merger Transaction
At the Second Stage Closing, subject to prior satisfaction of the Second Stage Closing Conditions, Parent will acquire the remaining issued and outstanding capital stock of the Company for up to $180 million, subject to certain deductions, by way of a reverse subsidiary merger transaction, in which Merger Sub will merge with and into the Company and the Company will be the surviving corporation in the Merger Transaction and will be Delaware corporation wholly-owned subsidiary of Parent, and the separate corporate existence of Merger Sub will cease.
56

TABLE OF CONTENTS
Upon consummation of the Merger Transaction, the certificate of incorporation and the by-laws of the Company shall be amended in their entirety as set forth in Exhibits M and N to the SPMA, respectively, and, as so amended, shall be the certificate of incorporation and by-laws of the surviving corporation until thereafter amended in accordance with applicable legal requirements.
The members of the board of directors of Merger Sub immediately prior to the effective time of the Merger Transaction will be the initial directors of the surviving corporation and will serve until their successors are duly elected or appointed and qualified or until their earlier death, resignation or removal in accordance with the certificate of incorporation and the bylaws of the surviving corporation. The officers of Merger Sub immediately prior to the effective time will be the initial officers of the surviving corporation and will serve until their successors are duly elected or appointed and qualified or until their earlier death, resignation or removal in accordance with the certificate of incorporation and the bylaws of the surviving corporation.
When the Stock Purchase Transaction and the Merger Transaction Become Effective
If the SPMA Proposal receives the Company stockholder approval, the closing of the Stock Purchase Transaction shall take place no later than five business days after the satisfaction or waiver of the conditions to the closing of the Stock Purchase Transaction provided for in the SPMA, or at such later time as may be agreed by Parent and the Company in writing, as described in the section entitled “The SPMA — Conditions to Completion of the Stock Purchase Transaction and the Merger Transaction” beginning on page 69 of this proxy statement.
The closing of the Merger Transaction shall take place no later than five business days after the satisfaction or waiver of the conditions to the closing of the Merger Transaction provided for in the SPMA, or at such later time as may be agreed by Parent and the Company in writing, as described in the section entitled “The SPMA — Conditions to Completion of the Stock Purchase Transaction and the Merger Transaction” beginning on page 69 of this proxy statement.
Effect of the Merger Transaction on the Common Stock of the Company and Merger Sub
At the effective time of the Merger Transaction, each share of the Company’s common stock issued and outstanding immediately prior to the effective time of the Merger Transaction (other than the Cancelled Shares and Dissenting Shares, each as defined below) will be converted into the right to receive (i) a pro rata portion, based on the fully diluted capitalization of the Company immediately prior to the effective time of the Merger Transaction, of the total merger consideration of up to $180 million, subject to certain deductions, which portion is currently expected to be approximately $13.92 per share; and (ii) a CVR which represents the right to receive contingent cash payments upon the achievement of certain milestones relating to annual net sales and gross profit targets of IV Tramadol, pursuant to the CVR Agreement.
Each share of common stock, par value $0.0001 per share, of Merger Sub issued and outstanding immediately prior to the effective time of the Merger Transaction shall be converted into and become one newly issued, fully paid, and non-assessable share of common stock, par value $0.0001 per share, of the surviving corporation with the same rights, powers, and privileges as the shares so converted and shall constitute the only outstanding shares of capital stock of the surviving corporation.
Cancelled Shares
At the effective time of the Merger Transaction, as a result of the Merger Transaction and without any action on the part of the Company, Parent Merger Sub or any holder of capital stock thereof, each common share, Class A Preferred Share or share of any other class or series of shares of capital stock of the Company that is owned by the Company, Parent or Merger Sub (as treasury stock or otherwise) or any of their respective direct or indirect wholly-owned subsidiaries as of immediately prior to the effective time of the Merger Transaction will automatically be cancelled and retired and will cease to exist, and no consideration will be delivered in exchange therefor.

TABLE OF CONTENTS
Dissenting Shares
Shares of our common stock issued and outstanding immediately prior to the effective time of the Merger Transaction and held by a holder who has properly exercised appraisal rights of such shares in accordance with Section 262 of the DGCL and has not subsequently failed to perfect or otherwise waived, withdrawn, or lost such holder’s appraisal rights under the DGCL with respect to such shares, which we refer to as the “Dissenting Shares” (until such time as such holder fails to perfect or otherwise waives, withdraws, or loses such holder’s appraisal rights under the DGCL with respect to such shares) will be canceled without payment of any form of consideration and cease to exist, subject to certain rights of the dissenting stockholders as described below.
No person who has timely and properly demanded appraisal of his, her or its shares of the Company’s common stock pursuant to and in accordance with Section 262 of the DGCL shall be entitled to receive the Merger Consideration with respect to the Dissenting Shares owned by such person, but instead such holder will be entitled to receive such consideration as may be determined to be due to such dissenting holder pursuant to Section 262 of the DGCL (or any successor provision), unless and until such holder has failed to perfect or has effectively withdrawn such demand or lost its, his or her rights to appraisal under the DGCL or if a court of competent jurisdiction shall determine that such holder is not entitled to the relief provided by Section 262 of the DGCL.
If, after the effective time, any holder of Dissenting Shares has failed to perfect or has effectively withdrawn or lost such right, such holder’s shares of the Company’s common stock will thereupon be treated as if they had been converted into and become exchangeable for the right to receive, as of the effective time, the Merger Consideration for each such share of our common stock owned by such holder, without interest and less any applicable withholding taxes. A summary of the appraisal rights available to the holders of shares of the Company common stock is provided in the section entitled “The Special Meeting and the Stock Purchase Transaction and the Merger Transaction — Rights of Appraisal” beginning on page 41 and a copy of Section 262 of the DGCL is included with this proxy statement as Annex C.
Treatment of the Company’s Preferred Stock
Fortress owns all of the issued and outstanding shares of the Company’s Class A Preferred Stock.

Treatment of Stock Options, Other Stock-Based Compensation and Warrants
Company Stock Options
The Company shall take all requisite action so that, prior to the effective time of the Merger Transaction, each option to acquire our common stock, each of which we refer to as a “Company stock option”, that is then-outstanding under any Company incentive plan shall become vested and exercisable and, if the fair market value of a share of common stock is then in excess of the per share exercise price of the Company stock option, such Company stock option shall be exercised pursuant to the terms and conditions of the applicable Company stock option award agreement, with any taxes withheld with respect to such exercise, and each share of common stock received by the former holder of a Company stock option in connection with such exercise shall be cancelled and converted automatically into the right to receive the Merger Consideration.
Company Restricted Shares
The Company shall take all requisite action so that, immediately prior to the effective time of the Merger Transaction, each share of our common stock subject to vesting, repurchase, or other lapse of restrictions, each of which we refer to as a “Company restricted share”, that is then-outstanding under any Company incentive plan shall vest in full and become free of restrictions, with any taxes withheld with respect to the fair market value of such Company restricted share, and shall be cancelled and converted automatically into the right to receive the Merger Consideration.

Promptly after the effective time of the Merger Transaction, Parent shall send or shall cause the paying agent to send to each holder of record of shares of the Company’s common stock immediately prior to the effective time of the Merger Transaction (other than the Cancelled Shares or the Dissenting Shares): (i) a

TABLE OF CONTENTS
letter of transmittal in specifying that delivery will be effected, and risk of loss and title to the shares of our common stock will pass, only upon delivery to the paying agent of  (A) in the case of certificated shares of our common stock, the certificates (or affidavits of loss in lieu of the certificates as provided in the SPMA), or (B) in the case of book-entry shares of our common stock, the book-entry shares (such letter of transmittal will be in such form and have such other provisions as Parent and the Company may reasonably agree); and (ii) instructions for use in effecting the surrender of the certificates (or affidavits of loss in lieu of the certificates as provided in the SPMA) or book-entry shares in exchange for the Merger Consideration.
Upon surrender of certificates (or affidavits of loss in lieu of the certificates as provided in the SPMA) or book-entry shares of our common stock for cancellation to the paying agent in accordance with the terms of a letter of transmittal that has been duly completed and validly executed in accordance with the instructions thereto, or in the case of a Book-Entry Share, receipt of an “agent’s message” by the paying agent (or such other evidence, if any, of transfer as the paying agent may reasonably request), the holder of such certificate or book-entry share of our common stock will be entitled to receive in exchange therefor a cash amount in immediately available funds less any required tax withholdings equal to (x) the number of shares of our common stock represented by such certificate (or affidavit of loss in lieu of the certificate as provided in the SPMA) or the number of book-entry shares of our common stock, as the case may be, multiplied by (y) the Merger Consideration, and any certificate or book-entry shares so surrendered will forthwith be cancelled. No interest will be paid or accrued on any amount payable upon due surrender of the certificates (or affidavits of loss in lieu thereof) or book-entry shares of our common stock.
In the event any certificate has been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such certificate to be lost, stolen or destroyed and, if required by Parent, the posting by such person of a bond in such reasonable amount as Parent or the paying agent may direct, the paying agent or the surviving corporation will issue a check in the amount (after giving effect to any required tax withholdings) equal to the number of shares of our common stock represented by such lost, stolen or destroyed certificate multiplied by the Merger Consideration.
Each of the paying agent, Parent, Merger Sub and the surviving corporation will be entitled to deduct and withhold from the Merger Consideration otherwise payable pursuant to the SPMA to any holder of shares of the Company’s common stock such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code, or any other applicable state, local or foreign tax law. To the extent that amounts are so withheld by the paying agent, Parent, Merger Sub or the surviving corporation, as the case may be, such withheld amounts will be treated for all purposes of the SPMA as having been paid to the holder of shares of the Company’s common stock in respect of which such deduction and withholding was made by the paying agent, Parent, Merger Sub or the surviving corporation, as the case may be.

TABLE OF CONTENTS
Notwithstanding the foregoing, the Board of Directors of the Company is permitted to:

participate in negotiations or discussions with any third party that has made (and not withdrawn) a bona fide, unsolicited Takeover Proposal in writing that the Board determines in good faith, after consultation with its outside legal counsel and independent financial advisor, constitutes or could reasonably be expected to result in a superior proposal; and

thereafter furnish to such third party non-public information relating to the Company pursuant to an executed confidentiality and standstill agreement (a copy of which confidentiality and standstill agreement shall be promptly (in all events within 24 hours) provided for informational purposes only to Parent) no less favorable to the Company than the confidentiality agreement between the Parent and the Company,
only if the Board determines in good faith, after consultation with its outside legal counsel and independent financial advisor, that the failure to take such action in connection with such written (and not withdrawn) Takeover Proposal would reasonably be expected to result in the Board breaching its fiduciary duties under applicable legal requirements. Such activities shall be terminated immediately in connection with any withdrawal of such Takeover Proposal or, in the case of any changes to such Takeover Proposal, if such changes would have not led to such determination had those changes been in effect at the time of the original determination.
The Board shall not take any of the above actions unless the Company shall have delivered to Parent a prior written notice advising Parent that it intends to take such action.
Under the SPMA, a “Takeover Proposal” means an inquiry, proposal, or offer from, or indication of interest in making a proposal or offer by, any Person or group (other than Parent and its Affiliates, including Merger Sub), written or oral, binding or non-binding, relating to any transaction or series of transactions, involving any direct or indirect: (a) acquisition, purchase, assignment, lease, license or transfer (including the granting or provision of any waiver, covenant not to sue, agreement to refrain from any conduct, or rights to proceeds, sue, or collect or retain damages or other payments with respect to) of (i) any Revogenex License Assets or Manufacturing Agreement Assets or (ii) assets of the Company equal to 15% or more of the fair market value of the Company’s assets or to which 15% or more of the Company’s net revenues or net income are attributable; (b) acquisition or purchase of equity which would result in any Person or group (other than Parent and its Affiliates, including Merger Sub) together with all Affiliates thereof, beneficially owning 15% or more of the voting equity interests of the Company; (c) tender offer or exchange offer that if consummated would result in any Person or group (as defined in Section 13(d) of the Exchange Act) beneficially owning (within the meaning of Section 13(d) of the Exchange Act) 15% or more of the voting power of the Company or the surviving entity, as applicable; (d) merger, consolidation, other business combination, liquidation, dissolution (or the adoption of a plan of liquidation or dissolution), share exchange, recapitalization or other corporate reorganization or similar transaction to any of the foregoing involving the Company, pursuant to which such Person or group (as defined in Section 13(d) of the Exchange Act) would (A) own any Revogenex License Assets or any Manufacturing Agreement Assets, (B) own assets of the Company equal to 15% or more of the fair market value of the Company’s assets or to which 15% or more of the Company’s (or the surviving entity’s, as applicable) net revenues or net income are attributable, or (C) beneficially own 15% or more of the voting equity interests of the Company (or the surviving entity, as applicable; (e) incurrence or assumption by the Company, or the Company otherwise becoming directly or indirectly liable for, any Indebtedness (including any security convertible or exercisable for or exchangeable into any capital stock of, or other equity interest in, the Company) in excess of  $20 million in the aggregate; or (f) any combination of the foregoing.
Change of Recommendation; Superior Proposals
The SPMA provides that the Board is not permitted to:

withhold, withdraw or modify (or publicly propose to resolve to withhold, withdraw or modify), in a manner adverse to Parent, the Board recommendation;

fail to include the Board recommendation in this proxy statement;
65

TABLE OF CONTENTS

approve, adopt or recommend, or propose to approve, adopt or recommend, any Takeover Proposal;

fail to recommend against acceptance of any tender offer or exchange offer for our common stock within ten business days after the commencement of such offer;

fail to reaffirm (publicly, if so requested by Parent) the Board recommendation within ten business days after the date any Takeover Proposal (or material modification thereto) or after any announcement of an intention (whether or not conditional) to make a Takeover Proposal is first publicly disclosed by the Company or the Person making such Takeover Proposal (or is otherwise made public or sent to stockholders of the Company);

make any public statement inconsistent with the Board recommendation;

agree to take any of the foregoing actions, which we refer to together as the “Company Adverse Recommendation Change”; or

enter into a Company Acquisition Agreement.
Despite the foregoing restrictions, at any time prior to the receipt of the Company stockholder approval, and subject to compliance with the SPMA’s requirements with respect to the Company’s stockholder meeting and the proxy statement, and the SPMA’s restrictions with respect to solicitation and acquisition proposals, the SPMA permits the Board to make a Company Adverse Recommendation Change or enter into a Company Acquisition Agreement, if:

the Company has given Parent written notice of its intention to make a Company Adverse Recommendation Change or enter into a Company Acquisition Agreement at least five (5) business days prior to its taking such action, which we refer to as the “Superior Proposal Notice Period”;

such notice states expressly that the Company has received a Takeover Proposal that the Board intends to declare a superior proposal and that the Company Board intends to effect a Company Adverse Recommendation Change and/or the Company intends to enter into a Company Acquisition Agreement;

the Company attaches to such notice the most current version of the proposed agreement and any related documents (which version(s) shall be updated on a prompt basis) and the identity of the third party making such superior proposal;

during such Superior Proposal Notice Period, the Company shall, and shall cause its representatives to, negotiate with Parent in good faith to make such adjustments in the terms and conditions of the SPMA so that such Takeover Proposal ceases to constitute a superior proposal (taking into account any termination fee and expense reimbursement provisions applicable), if Parent, in its discretion, proposes to make such adjustments;

the Board determines in good faith, after consulting with its outside legal counsel and independent financial advisor, that such Takeover Proposal that was a superior proposal continues to be a superior proposal after taking into account any adjustments made by Parent during such five (5) business day period; and

prior to or simultaneously with entering into any Company Acquisition Agreement, the Company shall have terminated the SPMA and paid the $10.0 million termination fee to Parent.
The SPMA defines the term “Superior Proposal” as a bona fide written proposal made by a third party to acquire, directly or indirectly, all of the Company securities then outstanding or all or substantially all of the assets of the Company, which, taking into account all legal, financial, regulatory, financing, conditionality, timing and other aspects of such proposal (including any termination fee and expense reimbursement provisions applicable, including the termination fee), satisfies all of the following requirements: (i) such superior proposal is reasonably expected by the Board to be consummated on the terms proposed; (ii) to the extent financing is required, such financing is then fully committed by creditworthy financial institutions of nationally recognized reputation; and (iii) such superior proposal is on
66

TABLE OF CONTENTS
terms that the Board determines in its good faith judgment (based on the advice of the Company’s outside legal counsel and independent financial advisor) to be more favorable to the Company and the holders of the common stock from a financial point of view than the transactions with the Parent.
Upon any material revision to the terms of a Superior Proposal after commencement of the Superior Proposal Notice Period, including any revision in price, the Superior Proposal Notice Period shall be extended, if applicable, to ensure that at least five business days remain in the Superior Proposal Notice Period subsequent to the time the Company notifies Parent of any such material revision (there may be multiple extensions).
Commercially Reasonable Efforts
Each of the parties to the SPMA agrees to use commercially reasonable efforts to take or cause to be taken all actions, and do or cause to be done all things, reasonably necessary, proper or advisable on its part under the SPMA, the Ancillary Agreements and applicable legal requirements to consummate and make effective the transactions contemplated by the SPMA and the Ancillary Agreements.
Fees and Expenses
Except as otherwise provided in the SPMA, each party will bear its own costs and expenses in connection with the SPMA and the transactions contemplated therein.
Indemnification; Directors’ and Officers’ Insurance
Under the terms of the SPMA, Parent and Merger Sub agree that all rights to indemnification, advancement of expenses and exculpation by the Company in favor of each person who is, or was been at any time prior to the signing date of the SPMA or who becomes prior to the consummation of the Merger Transaction, an officer or director of the Company, each of which we refer to as an “Indemnified Party”, as provided in the certificate of incorporation (including any certificate of designations) or by-laws of the Company, in each case as in effect on the signing date of the SPMA, or pursuant to any other contracts in effect on the date hereof, shall be assumed by the surviving corporation and shall remain in full force and effect in accordance with their terms, and, in the event that any proceeding is pending or asserted or any claim made during such period, until the final disposition of such proceeding or claim.
For a period of six years from the consummation of the Merger Transaction, Parent and the surviving corporation shall indemnify and hold harmless each Indemnified Party against all losses, claims, damages, liabilities, fees, expenses, judgments, and fines arising in whole or in part out of actions or omissions in their capacity as such occurring at or prior to the consummation of the Merger Transaction (including in connection with the transactions contemplated by the SPMA), and shall reimburse each Indemnified Party for any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any such losses, claims, damages, liabilities, fees, expenses, judgments, and fines as such expenses are incurred, subject to the surviving corporation’s receipt of an undertaking by such Indemnified Party to repay such legal and other fees and expenses paid in advance if it is ultimately determined in a final and non-appealable judgment of a court of competent jurisdiction that such Indemnified Party is not entitled to be indemnified under applicable legal requirements; provided, however, that the surviving corporation will not be liable for any settlement effected without the surviving corporation’s prior written consent (which consent shall not be unreasonably withheld, conditioned, or delayed).
The surviving corporation shall, and Parent shall cause the surviving corporation to: (i) maintain in effect for a period of six years after the effective time of the Merger Transaction, if available, the current policies of directors’ and officers’ liability insurance maintained by the Company immediately prior to the effective time of the Merger Transaction (provided, that the surviving corporation may substitute therefor policies, of at least the same coverage and amounts and containing terms and conditions that are not less advantageous to the directors and officers of the Company when compared to the insurance maintained by the Company as of the date hereof); or (ii) obtain as of the effective time of the Merger Transaction “tail” insurance policies with a claims period of six years from the effective time of the Merger Transaction effective time of the Merger Transaction with at least the same coverage and amounts and containing terms
67

TABLE OF CONTENTS
and conditions that are not less advantageous to the directors and officers of the Company, in each case with respect to claims arising out of or relating to events which occurred before or at the effective time of the Merger Transaction effective time of the Merger Transaction (including in connection with the transactions contemplated by the SPMA); provided, however, that in no event will the surviving corporation be required to expend an annual premium for such coverage in excess of 200 percent of the last annual premium paid by the Company for such insurance prior to the date of the SPMA, which amount is determined in accordance with Schedule 8.9 of the SPMA (the “Maximum Premium”). If such insurance coverage cannot be obtained at an annual premium equal to or less than the Maximum Premium, the surviving corporation will obtain, and Parent will cause the surviving corporation to obtain, that amount of directors’ and officers’ insurance (or “tail” coverage) obtainable for an annual premium equal to the Maximum Premium.
Concurrently with the execution and delivery of the SPMA, the Parent and Fortress entered into the Indemnification Agreement, pursuant to which Fortress agreed to indemnify and hold harmless the Parent from and against all losses arising out of any breach or inaccuracy of any representation or warranty of the Company contained in the SPMA or any ancillary agreement. Pursuant to the Indemnification Agreement, except in the case of fraud or intentional misrepresentation, the maximum liability of Fortress (other than with respect to any breach or inaccuracy of any Fundamental Representation) is limited to $7 million. Except in the case of fraud or intentional misrepresentation, the maximum liability of Fortress solely with respect to any breach or inaccuracy of any Fundamental Representation is limited to $35 million. Claims agreed to or adjudicated prior to the Merger Transaction will be reduced from the Merger Consideration. Claims surviving the Merger Transaction and agreed to or adjudicated after the Merger Transaction will be reduced from amounts payable under the CVR Agreement.

Each of the Company and Parent will pay half of any fees associated with any filings under the HSR Act in connection with the SPMA. The Company will pay all fees or make other payments provided for under legal requirements to any Governmental Authority in order to obtain any such authorizations, consents, orders or approvals.

Parent shall have the right to participate in the defense of any such Proceeding.

Governing Law
The SPMA is and will be interpreted, construed and governed by and in accordance with the law of the State of Delaware, without regard to the conflict of law principles thereof.
Remedies
No termination of the SPMA will relieve any party to the SPMA of any liability or damages to the other party resulting from any willful and material breach of the SPMA.

Such information can be found elsewhere in this proxy statement and in the public filings we make with the SEC, as described in the section entitled “Where You Can Find More Information” beginning on page 87.
The CVR Agreement may be subject to any reasonable revisions that are requested by the Rights Agent (provided that such revisions are not, individually or in the aggregate, detrimental or adverse, taken as a whole, to any person in whose name a CVR is registered in the CVR register (a “CVR Holder”). Avenue will cooperate, including by making changes to the form of CVR Agreement, as necessary to ensure that the CVRs are not subject to registration under the Securities Act, the Exchange Act or any applicable state securities or “blue sky” laws.
Capitalized terms used but not defined in this portion of the proxy statement shall have the respective meanings ascribed to them in the CVR Agreement.
Appointment of Rights Agent
Under the SPMA, the Company shall coordinate with Parent, sufficiently in advance of the Second Stage Closing, to find a reasonably suitable Rights Agent with respect to the CVR Agreement, and shall cooperate with Parent to finalize the CVR Agreement and have it fully executed and delivered on or prior to the Second Stage Closing.
The CVR Agreement
The CVRs will be governed by the terms of the CVR Agreement, which will be entered into at, or prior to, the effective time of the Merger Transaction by Avenue and the Rights Agent.
As provided in the SPMA, each share of common stock, par value $0.0001, of the Company issued and outstanding immediately prior to the effective time of the Merger Transaction (other than the Cancelled Shares and the Dissenting Shares) will be converted into the right to receive, in addition to the per share cash consideration, one CVR.

See the section entitled “Material U.S. Federal Income Tax Consequences of the Merger Transaction” beginning on page 36.
Indemnity
Claims made under the SPMA and agreed to or adjudicated prior to the Merger Transaction will be reduced from the Merger Consideration. Claims surviving the Merger Transaction and agreed to or adjudicated after the Merger Transaction will be reduced from amounts payable under the CVR Agreement.
Milestone Events

1.
During the Initial Period, upon IV Tramadol generating $325 million or more in net sales in a calendar year, each CVR Holder shall be entitled to receive her, his or its applicable CVR percentage (the quotient of  (i) the number of CVRs held by such Holder, divided by (ii) the fully diluted capitalization (the Cancelled Shares) as of immediately prior to the Merger Transaction) multiplied by an aggregate amount equal to the applicable percentage ((i) if IV Tramadol generated less than $400 million in net sales during such calendar year, 10% of gross profit generated by IV Tramadol during the such calendar year; (ii) if IV Tramadol generated between $400 million and $500 million in net sales during such calendar year, 12.5% of gross profit generated by IV Tramadol during the such calendar year; or (iii) if IV Tramadol generated more than $500 million in net sales during such calendar year, 15% of gross profit generated by IV Tramadol during the such calendar year) multiplied by the gross profit generated by IV Tramadol during such calendar year.
2.
If  $1.5 billion in aggregate net sales of IV Tramadol generated from and after the Initial Period is achieved during the Subsequent Period, which we refer to as the Subsequent Period Net Sales Target, then (x) with respect to the calendar year in which the Subsequent Period Net Sales Target is achieved, if during the Stub Period (the period during the year in which the Subsequent Period Net Sales Target was achieved commencing one day after the date on which the Subsequent Period Net Sales Target was achieved and ending on December 31 of such calendar year), IV Tramadol generates $100 million or more in annualized net sales, then each CVR Holder shall be entitled to receive her, his or its CVR Percentage (with respect to a CVR Holder as of the applicable date of determination, the quotient of  (i) the number of CVRs held by such Holder, divided by (ii) the fully diluted capitalization (excluding shares to be cancelled and retired) multiplied by an aggregate amount equal to 20% of the gross profit generated by IV Tramadol with respect to such Stub Period and (y) during the remainder of the Subsequent Period, with respect to each calendar year after the calendar year in which the Subsequent Period Net Sales Target was achieved, upon
78

TABLE OF CONTENTS
IV Tramadol generating $100 million or more in Net Sales in such calendar year, each CVR Holder shall be entitled to receive her, his or its CVR Percentage multiplied by an aggregate amount equal to 20% of the gross profit generated by IV Tramadol during such calendar year. If the Subsequent Period Net Sales Target is achieved during the Initial Period, then, during the Subsequent Period, upon IV Tramadol generating $100 million or more in net sales in a calendar year, each CVR Holder shall be entitled to receive her, his or its CVR Percentage multiplied by an aggregate amount equal to 20% of the gross profit generated by IV Tramadol during such calendar year.
Milestone Payments
Upon achievement of a Milestone at any time prior to the expiration of its applicable Milestone period, then on or prior to, but in any event and no later than, May 31 of the calendar year following the calendar year triggering the Milestone, which we refer to as the “Milestone Payment Date”, the Company shall deliver or cause to be delivered to the Rights Agent: (i) written notice indicating that the Milestone has been achieved and that the Holders are entitled to receive the applicable Milestone payment; and (ii) a wire transfer of immediately available funds to an account designated by the Rights Agent, in the aggregate amount equal to the Milestone payment payable to all of the Holders with respect to such Milestone. After receipt of the wire transfer described in the foregoing sentence, the Rights Agent will promptly (and, in any event, within five business days) pay (x) by one lump sum wire payment to The Depository Trust Company, which we refer to as DTC, for any Holder who is a former street name holder of common stock of the Company; and (y) for all other Holders, by check mailed, first-class postage prepaid, to the address of each Holder set forth in the CVR register or by other method of delivery as specified by the applicable Holder in writing to the Rights Agent (we refer to the amount each Holder is entitled to receive in respect to such Milestone as a “Milestone Payment”, and to such aggregate cash amounts in (x) and (y) together as the “Aggregate Milestone Payment”). The Rights Agent shall hold the Aggregate Milestone Payment in a non-interest bearing account until such payment is made in accordance with the foregoing sentence. However, in no event shall the Company be required to pay a Milestone payment more than once, and the Company shall not be required to pay a Milestone Payment if the Milestone occurs after the expiration of the Milestone Period.
Any portion of any Aggregate Milestone Payment that remains undistributed to the Holders six months after the date of the Milestone Payment Date shall be delivered by the Rights Agent to the Company, upon demand, and any Holder may thereafter look only to the Company for payment of such Milestone payment, without interest, but such Holder shall have no greater rights against the Company than those accorded to general unsecured creditors of the Company under applicable law.
Representatives
The Company shall deploy, within 12 months after the initial commercial supply of the Product in the United States, 80 or more sales representatives whose aggregate time devotion to sales of the Product shall be at least the equivalent of 80 Reps devoting at least 75% of their time (on an aggregate basis) to sales of the Product. The Company shall maintain such level of sales representatives (to be measured at 24 and 36 months after the initial commercial supply of the Product in the United States) until the date that is 36 months after the initial commercial supply of the Product in the United States. During the Milestone Periods, neither the Company nor any of its Affiliates shall take any action the sole purpose of which is to avoid the achievement of the Milestone or the payment of the Milestone payments.
Characteristics of the CVRs; Restrictions on Transfer
The CVRs will not be evidenced by a certificate or other instrument. The CVRs will not have any voting or dividend rights, and interest will not accrue on any amounts payable on the CVRs to any CVR Holder. The CVRs will not represent any equity or ownership interest in the Company or in any constituent company to the Merger Transaction or any of their respective affiliates.
The CVRs may not be sold, assigned, transferred, pledged, encumbered or in any other manner transferred or disposed of, in whole or in part, other than pursuant to any of the following permitted transfers: (a) upon death of a CVR Holder by will or intestacy; (b) by instrument to an inter vivos or
79

TABLE OF CONTENTS
testamentary trust in which the CVRs are to be passed to beneficiaries upon the death of the trustee; (c) pursuant to a court order; (d) by operation of law (including by consolidation or merger) or without consideration in connection with the dissolution, liquidation or termination of any corporation, limited liability company, partnership or other entity; or (e) in the case of CVRs payable to a nominee, from a nominee to a beneficial owner (and, if applicable, through an intermediary) or from such nominee to another nominee for the same beneficial owner, in each case to the extent allowable by DTC. Any attempted transfer, in whole or in part (other than a permitted transfer as set forth in the immediately preceding sentence), other than pursuant to the foregoing permitted transfers, will be void and of no effect.
Amendment and Termination of the CVR Agreement
Amendments Without Consent of Holders
Without the consent of any CVR Holder or the Rights Agent, the Company, at any time and from time to time, may enter into one or more amendments to the CVR Agreement, for any of the following purposes, so long as, in the cases of clauses (ii) through (iv), such amendments do not, individually or in the aggregate, adversely affect the interests of the Holders, or adversely affect the rights, duties, responsibilities or protections of the Rights Agent to evidence the succession of another person to the Company and the assumption by any such successor of the covenants of the CVR Agreement:
(i)
to add to the covenants of the Company such further covenants, restrictions, conditions or provisions as the Company shall determine to be for the protection of the Holders;
(ii)
to cure any ambiguity, to correct or supplement any provision of the CVR Agreement that may be defective or inconsistent with any other provision herein, or to make any other provisions with respect to matters or questions arising under the CVR Agreement;

(iv)
to evidence the succession of another person as a successor rights agent and the assumption by any such successor of the covenants and obligations of the Rights Agent in accordance with the provisions of the CVR Agreement;
(v)
any other amendment hereto that does not adversely affect the legal rights under the CVR Agreement of any Holder; or
(vi)
to reduce the number of CVRs, in the event any CVR Holder agrees to transfer or renounce such CVR Holder’s rights under the CVR Agreement.

From and after the Merger Effective Time, all certificates representing shares of Merger Sub common stock shall be deemed for all purposes to represent the number of shares of common stock of the Surviving Corporation into which they were converted in accordance with the immediately preceding sentence.
Section 4.2 Surrender and Payment.
(a) Paying Agent; Payment Fund.   Prior to the Merger Effective Time, Buyer shall appoint a paying agent (the “Paying Agent”) to act as the agent for the purpose of paying the Cash Merger Consideration for: (i) the Certificates; and (ii) the Book-Entry Shares. At or promptly following the Merger Effective Time, Buyer shall deposit, or cause the Surviving Corporation to deposit, with the Paying Agent, sufficient funds to pay the aggregate Cash Merger Consideration that is payable in respect of all of the Common Shares represented by the Certificates and the Book-Entry Shares (other than: (A) shares to be cancelled and retired in accordance with Section 4.1(a); and (B) Dissenting Shares) (the “Payment Fund”) in amounts and at the times necessary for such payments. If for any reason the Payment Fund is inadequate to pay the amounts to which holders of shares shall be entitled under Section 4.1(b), Buyer shall take all steps necessary to enable or cause the Surviving Corporation promptly to deposit in trust additional cash with the Paying Agent sufficient to make all payments required under this Agreement. The Payment Fund shall not be used for any other purpose. All charges and expenses, including those of the Paying Agent in connection with the exchange of Common Shares for the Cash Merger Consideration, the R&WI Expense (as defined in Section 11.1) and any unpaid Broker Fees, as defined in Section 5.20 (collectively, the “Merger Fees”), shall be deducted from the Gross Amount pursuant to Section 4.1(b).

Promptly after the Merger Effective Time, Buyer shall send, or shall cause the Paying Agent to send, to each record holder of Common Shares immediately prior to the Merger Effective Time, a letter of transmittal and instructions (which shall specify that the delivery shall be effected, and risk of loss and title shall pass, only upon proper delivery of the Certificates or transfer of the Book-Entry Shares to the Paying Agent, and which letter of transmittal will be in customary form and have such other provisions as Buyer and the Surviving Corporation may reasonably specify) for use in such exchange.
(b) Procedures for Surrender; No Interest.   Each holder of Common Shares that have been converted into the right to receive the Merger Consideration shall be entitled to receive the Merger Consideration in respect of the Common Shares represented by a Certificate or Book-Entry Share only upon: (i) in the case of a Certificate, surrender to the Paying Agent of such Certificate, together with a duly completed and validly executed letter of transmittal and such other documents as may reasonably be requested by the Paying Agent; or (ii) in the case of a Book-Entry Share, receipt of an “agent’s

message” by the Paying Agent (or such other evidence, if any, of transfer as the Paying Agent may reasonably request) in respect of such Book-Entry Share. Until so surrendered or transferred, as the case may be, and subject to the terms set forth in Section 4.3, each such Certificate or Book-Entry Share, as applicable, shall represent after the Merger Effective Time for all purposes only the right to receive, in accordance with this Agreement and upon compliance by the holder thereof with Section 4.2 hereof, the Merger Consideration payable in respect thereof. No interest shall be paid or accrued on the Merger Consideration. After the Merger Effective Time, no dividend or other distribution shall be paid in respect of any Common Share, Class A Preferred Share or other share of any class or series of capital stock of the Company and each Certificate or Certificates or Book-Entry Share or Book-Entry Shares so surrendered or transferred, as the case may be, shall immediately be cancelled and retired (except for the right to receive the Merger Consideration pursuant to the provisions of this Article 4).
(c) Investment of Payment Fund.   Until disbursed in accordance with the terms and conditions of this Agreement, the cash in the Payment Fund will be invested by the Paying Agent, as directed by Buyer or the Surviving Corporation, in: (i) obligations of or fully guaranteed by the United States or any agency or instrumentality thereof and backed by the full faith and credit of the United States with a maturity of no more than 30 days; (ii) commercial paper obligations rated A-1 or P-1 or better by Moody’s Investors Service, Inc. or Standard & Poor’s Corporation, respectively; or (iii) certificates of deposit, bank repurchase agreements, or banker’s acceptances of commercial banks with capital exceeding $1,000,000,000 (based on the most recent financial statements of such bank that are then publicly available). No losses with respect to any investments of the Payment Fund will affect the amounts payable to the holders of Certificates or Book-Entry Shares. Any income from investment of the Payment Fund will be payable to Buyer or the Surviving Corporation, as Buyer directs.
(d) Payments to Non-Registered Holders.   If any portion of the Merger Consideration is to be paid to a Person other than the Person in whose name the surrendered Certificate or the transferred Book-Entry Share, as applicable, is registered, it shall be a condition to such payment that: (i) such Certificate shall be properly endorsed or shall otherwise be in proper form for transfer or such Book-Entry Share shall be properly transferred; and (ii) the Person requesting such payment shall pay to the Paying Agent any transfer or other Tax required as a result of such payment to a Person other than the registered holder of such Certificate or Book-Entry Share, as applicable, or establish to the reasonable satisfaction of the Paying Agent that such Tax has been paid or is not payable.
(e) Full Satisfaction.   All Merger Consideration paid upon the surrender of Certificates or transfer of Book-Entry Shares in accordance with the terms hereof shall be deemed to have been paid in full satisfaction of all rights pertaining to the Common Shares formerly represented by such Certificate or Book-Entry Shares, and from and after the Merger Effective Time, there shall be no further registration of transfers of Common Shares on the stock transfer books of the Surviving Corporation. If, after the Merger Effective Time, Certificates or Book-Entry Shares are presented to the Surviving Corporation, they shall be cancelled (and, to the extent the holders thereof are entitled thereto, exchanged for the Merger Consideration provided for, and in accordance with the procedures set forth, in this Section 4.2).
(f) Termination of Payment Fund.   Any portion of the Payment Fund that remains unclaimed by the holders of Common Shares nine months after the Merger Effective Time shall be returned to Buyer, upon demand, and any such holder who has not exchanged Common Shares for the Merger Consideration in accordance with this Section 4.2 prior to that time shall thereafter look only to the Surviving Corporation (subject to abandoned property, escheat, or other similar laws), as general creditors thereof, for payment of the Merger Consideration without any interest. Notwithstanding the foregoing, Buyer shall not be liable to any holder of Common Shares for any amounts paid to a public official pursuant to applicable abandoned property, escheat, or similar laws. Any amounts remaining unclaimed by holders of Common Shares two years after the Merger Effective Time (or such earlier date, immediately prior to such time when the amounts would otherwise escheat to or become property of any governmental entity) shall become, to the extent permitted by applicable Legal Requirements, the property of Buyer free and clear of any claims or interest of any Person previously entitled thereto.

(g) Dissenting Shares Merger Consideration.   Any portion of the Merger Consideration made available to the Paying Agent in respect of any Dissenting Shares shall be returned to Buyer, upon demand.

(i) Set-Off; Surviving Indemnification Claims.   Notwithstanding this Agreement or the Contingent Value Rights Agreement to the contrary, (i) to the extent that Buyer shall exercise its set-off right pursuant to the Fortress Restrictive Covenants Agreement or the Lu Restrictive Covenants Agreement against any amount payable pursuant to Section 4.1(b), then such set-off amount shall reduce the payment obligation of Buyer, Merger Sub, the Company or their Affiliates or assigns under, and such amount shall not be required to be paid by the foregoing pursuant to, this Agreement or the Contingent Value Rights Agreement to the extent that such amount does not exceed the portion(s) of the amount(s) otherwise payable hereunder or thereunder to Fortress (or its assigns) or Lucy Lu (or her heirs or assigns), respectively, from time to time, and the Company, Buyer and the Paying Agent (or the Rights Agent (as defined in the Contingent Value Rights Agreement), if applicable) shall cooperate with each other to appropriately and equitably distribute the amount payable hereunder or thereunder by the Paying Agent (or the Rights Agent (as defined in the Contingent Value Rights Agreement), if applicable) to holders of Common Shares issued and outstanding immediately prior to the Merger Effective Time (other than: (i) shares to be cancelled and retired in accordance with Section 4.1(a); and (ii) Dissenting Shares), taking such set-off into account and in a manner that reduces the amount that Fortress (or its assigns) or Lucy Lu (or her heirs or assigns), as applicable are paid, (ii) with respect to any Post-Closing Indemnification Amount, if Fortress has actually paid in full to Buyer the Fortress Portion multiplied by such Post-Closing Indemnification Amount in accordance with the Indemnification Agreement, then the Company’s (or its Affiliates’ or assigns’) obligation to make a payment pursuant to the Contingent Value Rights Agreement shall be reduced by the Non-Fortress Portion multiplied by such Post-Closing Indemnification Amount, and such amount shall not be required to be paid thereunder by the foregoing, to the extent that such product does not exceed the amount payable thereunder excluding the portion thereof payable to Fortress (or its assigns), and the Company and the Rights Agent (as defined in the Contingent Value Rights Agreement) shall cooperate with each other to appropriately and equitably distribute the amount payable thereunder by the Rights Agent (as defined in the Contingent Value Rights Agreement) to holders of Common Shares issued and outstanding immediately prior to the Merger Effective Time (other than: (i) shares to be cancelled and retired in accordance with Section 4.1(a); and (ii) Dissenting Shares), taking such reduction into account and in a manner that reduces the amount that such holders (other than Fortress) are paid, (iii) with respect to any Post-Closing Indemnification Amount, if Fortress has not paid to Buyer the Fortress Portion multiplied by such Post-Closing Indemnification Amount in accordance with the Indemnification Agreement, then the Company’s (or its Affiliates’ or assigns’) obligation to make a payment pursuant to the Contingent Value Rights Agreement shall be reduced by such Post-Closing Indemnification Amount, and such amount shall not be required to be paid thereunder by the foregoing, and the Company and the Rights Agent (as defined in the Contingent Value Rights Agreement) shall cooperate with each other to appropriately and equitably distribute the amount

payable thereunder by the Rights Agent (as defined in the Contingent Value Rights Agreement) to holders of Common Shares issued and outstanding immediately prior to the Merger Effective Time (other than: (i) shares to be cancelled and retired in accordance with Section 4.1(a); and (ii) Dissenting Shares), taking such reduction into account and in a manner that reduces the amount that all such holders are paid, and (iv) if any Post-Closing Indemnification Amount is due, then the Company and the Rights Agent (as defined in the Contingent Value Rights Agreement) shall cooperate with each other to appropriately and equitably distribute the amount payable by the Rights Agent (as defined in the Contingent Value Rights Agreement) under the Contingent Value Rights Agreement to the holders of Common Shares issued and outstanding immediately prior to the Merger Effective Time (other than: (i) shares to be cancelled and retired in accordance with Section 4.1(a); and (ii) Dissenting Shares) such that the Non-Fortress Portion multiplied by the reasonable and documented legal fees and expenses incurred by Fortress in defending the Surviving Indemnification Claim relating to such Post-Closing Indemnification Amount shall first be paid by the Rights Agent (as defined in the Contingent Value Rights Agreement) pursuant to the Contingent Value Rights Agreement to Fortress (to the extent that it does not exceed the amount payable thereunder) and the remaining amount payable by the Rights Agent (as defined in the Contingent Value Rights Agreement) under the Contingent Value Rights Agreement shall be payable thereunder to all holders of Common Shares issued and outstanding immediately prior to the Merger Effective Time (other than: (i) shares to be cancelled and retired in accordance with Section 4.1(a); and (ii) Dissenting Shares). If any Losses included in any Post-Closing Indemnification Amount (i) reduced the amount payable by the Company or its Affiliates or assigns under the Contingent Value Rights Agreement pursuant to this Section 4.2(i) and (ii) are subsequently determined in a final judgment or award of a court of competent jurisdiction which is either not subject to any further appeals or the time for giving notice to take such appeals has lapsed and no such notice was filed to be lower than the amount that actually reduced the amount payable by the Company or its Affiliates or assigns under the Contingent Value Rights Agreement pursuant to this Section 4.2(i), then the Company shall transfer the difference between such amounts to the Rights Agent (as defined in the Contingent Value Rights Agreement) for further payment by it pursuant to Section 2.4 thereof, which payment shall be (i) deemed to have occurred as of the time that it would have otherwise been due pursuant to the Contingent Value Rights Agreement but for this Section 4.2(i) and (ii) made to the Persons entitled thereunder taking the foregoing clause (i) into account. Notwithstanding this Agreement or the Contingent Value Rights Agreement to the contrary, if any Losses included in any Post-Closing Indemnification Amount (i) reduced the amount payable by the Company or its Affiliates or assigns under the Contingent Value Rights Agreement pursuant to this Section 4.2(i) and (ii) are subsequently determined in a final judgment or award of a court of competent jurisdiction which is either not subject to any further appeals or the time for giving notice to take such appeals has lapsed and no such notice was filed to be higher than the amount that actually reduced the amount payable by the Company or its Affiliates or assigns under the Contingent Value Rights Agreement pursuant to this Section 4.2(i), then the difference between such amounts shall be deemed to be a new Post-Closing Indemnification Amount with respect to which (x) the provisions of Section 2(g) of the Indemnification Agreement shall apply and (y) the provisions of this Section 4.2(i) shall apply to further reduce the amounts required to be paid by the Company or its Affiliates or assigns pursuant to the Contingent Value Rights Agreement.

the Fortress Portion, with respect to Fortress and its Affiliates and assigns, and the Non Fortress Portion, with respect to all holders of Common Shares issued and outstanding immediately prior to the Merger Effective Time (other than: (i) shares to be cancelled and retired in accordance with Section 4.1(a); and (ii) Dissenting Shares) other than Fortress) mutatis mutandis to this Section 4.2.
Section 4.3 Dissenting Shares.   Notwithstanding any provision of this Agreement to the contrary, including Section 4.1, Common Shares issued and outstanding immediately prior to the Merger Effective Time (other than shares cancelled in accordance with Section 4.1(a)) and held by a holder who has properly exercised appraisal rights of such shares in accordance with Section 262 of the DGCL and has not subsequently failed to perfect or otherwise waived, withdrawn, or lost such holder’s appraisal rights under the DGCL with respect to such shares (such Common Shares being referred to collectively as the “Dissenting Shares” until such time as such holder fails to perfect or otherwise waives, withdraws, or loses such holder’s appraisal rights under the DGCL with respect to such shares) shall not be converted into a right to receive the Merger Consideration, but instead shall be entitled to only such rights as are granted by Section 262 of the DGCL; provided, however, that if, after the Merger Effective Time, such holder fails to perfect, waives, withdraws, or loses such holder’s right to appraisal pursuant to Section 262 of the DGCL or if a court of competent jurisdiction shall determine that such holder is not entitled to the relief provided by Section 262 of the DGCL, such Common Shares shall be treated as if they had been converted as of the Merger Effective Time into the right to receive the Merger Consideration in accordance with Section 4.1(b), without interest thereon, upon surrender of such Certificate formerly representing such share or transfer of such Book-Entry Share, as the case may be. The Company shall provide Buyer prompt written notice of any demands received by the Company for appraisal of Common Shares, any waiver or withdrawal of any such demand, and any other demand, notice, or instrument delivered to the Company prior to the Merger Effective Time that relates to such demand, and Buyer shall have the opportunity and right to direct all negotiations and proceedings with respect to such demands. Except with the prior written consent of Buyer, the Company shall not make any payment with respect to, or settle, or offer to settle, any such demands.
Section 4.4 Changes to Capital Stock; Adjustments to Merger Consideration.   Without limiting the other provisions of this Agreement, if at any time during the period between the Signing Date and the Merger Effective Time, any change in the outstanding shares of capital stock of the Company shall occur, including by reason of any issuance (including upon exercise of warrants), reclassification, recapitalization, stock split (including a reverse stock split), or combination, exchange, readjustment of shares, or similar transaction, or any stock dividend or distribution paid in stock, the Merger Consideration and any other amounts payable pursuant to this Agreement shall be equitably adjusted to proportionately reflect such change; provided, however, that this sentence shall not be construed to permit the Company to take any action with respect to its securities that is prohibited by the terms of this Agreement.
Section 4.5 Withholding Rights.   Each of the Paying Agent, Buyer, Merger Sub, and the Surviving Corporation shall be entitled to deduct and withhold from the consideration otherwise payable to any Person pursuant to this Agreement such amounts as may be required to be deducted and withheld with respect to the making of such payment under any Tax laws. To the extent that amounts are so deducted and withheld by the Paying Agent, Buyer, Merger Sub, or the Surviving Corporation, as the case may be, such amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which the Paying Agent, Buyer, Merger Sub, or the Surviving Corporation, as the case may be, made such deduction and withholding.
Section 4.6 Lost Certificates.   If any Certificate shall have been lost, stolen, or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen, or destroyed and, if required by Buyer, the posting by such Person of a bond, in such reasonable amount as Buyer or the Paying Agent may direct, as indemnity against any claim that may be made against Buyer or the Surviving Corporation with respect to such Certificate, the Paying Agent will issue, in exchange for such lost, stolen, or destroyed Certificate, the Merger Consideration to be paid in respect of the Common Shares formerly represented by such Certificate as contemplated under this Article 4.
Section 4.7 Treatment of Stock Options, Other Stock-Based Compensation and Warrants.
(a) Company Stock Options.   The Company shall take all requisite action so that, prior to the Merger Effective Time, each option to acquire Common Shares (each, a “Company Stock Option”)
A-20

TABLE OF CONTENTS
that is then-outstanding under any Company Plan (as in effect at the Signing Date and previously disclosed to Buyer), whether or not then vested or exercisable, shall become vested and exercisable and, if the fair market value of a Common Share (which, for this purpose, shall be the closing price per Common Share immediately prior to the Merger Effective Time) is then in excess of the per share exercise price of the Company Stock Option, such Company Stock Option shall be exercised pursuant to the terms and conditions of the applicable Company Stock Option award agreement (with any Taxes withheld with respect to such exercise), with each Common Share received by the former holder of a Company Stock Option in connection with such exercise entitled to receive the Merger Consideration pursuant to Section 4.1(b). For the avoidance of doubt, in the event that the per share exercise price under any Company Stock Option that is outstanding immediately prior to the Merger Effective Time is equal to or greater than the Merger Consideration, such Company Stock Option shall be cancelled as of the Merger Effective Time without payment therefor and shall have no further force or effect.
(b) Company Restricted Shares.   The Company shall take all requisite action so that, immediately prior to the Merger Effective Time, each Common Share subject to vesting, repurchase, or other lapse of restrictions (a “Company Restricted Share”) that is outstanding under any Company Plan immediately prior to the Merger Effective Time shall, by virtue of the Merger and without any action on the part of the holder thereof, vest in full and become free of restrictions (with any Taxes withheld with respect to the fair market value of such Company Restricted Share, which, for this purpose, shall be the closing price per Common Share immediately prior to the Merger Effective Time) and shall be cancelled and converted automatically, in accordance with the procedures set forth in this Agreement, into the right to receive the Merger Consideration pursuant to Section 4.1(b).
(c) Company Restricted Share Units.   The Company shall take all requisite action so that, immediately prior to the Merger Effective Time, each unit of Company Restricted Shares (a “RSU”), that is outstanding immediately prior to the Merger Effective Time, shall be accelerated in full and, in exchange therefor, each former holder of any such RSU shall be entitled to receive a number of Common Shares as is equal to (i) the total number of Common Shares subject to such RSU, less (ii) a number of Common Shares that would otherwise be issued to the holder pursuant to the RSU to be withheld by the Surviving Corporation in satisfaction of the tax withholding obligations arising as a result of the vesting and settlement of such RSU equal to a number of Common Shares having a fair market value (which, for this purpose, shall be the closing price per Common Share immediately prior to the Merger Effective Time) equal to the amount necessary to satisfy the withholding obligation based on the minimum applicable statutory withholding rates for federal, state and local income tax and payroll tax purposes (rounded up to the nearest whole share). Each such Common Share issued to a former holder of an RSU shall be entitled to receive the Merger Consideration pursuant to Section 4.1(b).
(d) Warrants.   Promptly after the Signing Date, the Company shall take all requisite action so that, prior to the First Stage Closing, each warrant to issue any Company Securities (each, a “Company Warrant”) that is outstanding shall be (i) exercised by the holder thereof, and converted into Common Shares, and such Company Warrant shall be cancelled without any Liability to the Company, or (ii) amended in writing (subject to Buyer’s prior review and consent to such amendment, such consent not to be unreasonably withheld), and fully executed by the Company and the applicable holder thereof, solely to provide that such Company Warrant shall, immediately prior to the Merger Effective Time, automatically, and without any action of the holder thereof or the Company, be converted into Common Shares, and that such Company Warrant shall be cancelled without any Liability to the Company.
(e) Resolutions and Other Company Actions.   Prior to the Merger Effective Time or the First Stage Closing, as applicable, the Company, the Company’s Board of Directors, and the compensation committee of such board, as applicable, shall have adopted any resolutions and taken any actions (including obtaining any employee consents) that may be necessary to effectuate the provisions of paragraphs (a), (b), (c) and (d) of this Section 4.7.
Section 4.8 Further Assurances.   If, at any time from and after the Merger Effective Time, the Company or Buyer reasonably believes or is advised that any further instruments, deeds, assignments or

assurances are reasonably necessary or desirable to consummate the Merger or to carry out the purposes and intent of this Agreement at or after the Merger Effective Time, then the Company, Buyer, the Surviving Corporation and their respective officers and directors shall execute and deliver all such proper deeds, assignments, instruments and assurances and do all other things reasonably necessary or desirable to consummate the Merger and to carry out the purposes and intent of this Agreement.

reasonable access, to the officers, employees, agents, offices, other facilities, properties, data and books and records of the Company, including financial and accounting information and working papers that Buyer may from time to time reasonably request and (ii) to furnish, as promptly as practicable, to Buyer, its Affiliates and their representatives such additional information regarding the Company as Buyer, its Affiliates and their representatives may from time to time reasonably request; provided, however, that such access will be provided upon reasonable notice, during normal business hours, and in a manner that will not unreasonably interfere with the conduct of the business of the Company. Notwithstanding anything to the contrary in this Agreement, the Company will not be required to disclose any information to Buyer if such disclosure would (i) invalidate any attorney-client privilege or (ii) contravene any applicable Legal Requirement or fiduciary duty. The Company acknowledges that Buyer may be subject to obligations under Legal Requirements, including obligations under the federal Physician Payments Sunshine Act and similar Legal Requirements relating to payments and gifts made to healthcare practitioners and Legal Requirements relating to fraud and abuse such as the False Claims Act, Anti-Kick Back Statute, Physician Self-Referral Law (Stark law), the Exclusion Provisions and the Civil Monetary Penalties Law, and that Buyer may require the Company’s support and cooperation to comply with such statutory obligations. The Company hereby agrees to reasonably cooperate with Buyer and to take all actions necessary, including providing information, to enable Buyer to comply with such obligations. No investigation pursuant to this Section 8.2 or information provided, made available or delivered pursuant to this Section 8.2 or otherwise, or any knowledge that any Person may have shall affect any representations or warranties or conditions or rights contained in this Agreement or any Ancillary Agreement.
Section 8.3 No Solicitation.
(a) The Company shall not (and shall cause its Affiliates not to), and shall not authorize or permit its directors, officers, employees, agents, advisors, legal counsel, investment bankers and other representatives (the foregoing Persons are referred to herein as “Representatives”) to, and shall instruct each of its Representatives not to, directly or indirectly, (x) solicit, initiate, or knowingly facilitate or encourage the submission of any Takeover Proposal or the making of any proposal that could reasonably be expected to lead to any Takeover Proposal, or (y) subject to Section 8.3(b): (i) conduct or engage in any discussions or negotiations with, disclose any non-public information relating to the Company to, afford access to the business, properties, assets, books, or records of the Company to, or knowingly assist, participate in, facilitate, or encourage any effort by, any third party that is seeking to make, or has made, any Takeover Proposal; (ii) (A) amend or grant any waiver under any standstill or similar agreement with the party providing such Takeover Proposal with respect to the applicable class of equity securities of the Company, or (B) approve any transaction under, or any third party becoming an “interested stockholder” under, Section 203 of the DGCL; or (iii) enter into any agreement in principle, letter of intent, term sheet, acquisition agreement, merger agreement, option agreement, joint venture agreement, partnership agreement, or other Contract relating to any Takeover Proposal (each, a “Company Acquisition Agreement”). Except as expressly permitted by Section 8.3(d), the Board of Directors of the Company shall not effect a Company Adverse Recommendation Change. The Company shall (and shall cause its Affiliates to) cease immediately and cause to be terminated, and shall not authorize or knowingly permit any of its Representatives to continue, and shall instruct each such Representatives to terminate, any and all existing activities, discussions, or negotiations, if any, with any third party conducted prior to the Signing Date with respect to any Takeover Proposal and shall use its reasonable best efforts to cause any such third party (and the Affiliates and Representatives of the Company or its Affiliates) in possession of non-public information in respect of the Company that was furnished by or on behalf of the Company to return or destroy (and confirm destruction of) all such information.
(b) Notwithstanding Section 8.3(a), prior to the Requisite Stockholder Approval, the Board of Directors of the Company, directly or indirectly through any Representative, may, subject to Sections 8.3(c) and (d): (i) participate in negotiations or discussions with any third party that has made (and not withdrawn) a bona fide, unsolicited Takeover Proposal in writing that the Company Board determines in good faith, after consultation with its outside legal counsel and independent financial advisor, constitutes or could reasonably be expected to result in a Superior Proposal; and (ii) thereafter furnish to such third party non-public information relating to the Company (provided, that the
A-41

TABLE OF CONTENTS
Company shall, substantially concurrently with the delivery to such Person, provide to Buyer any non-public information concerning the Company that is provided or made available to such Person or its Representatives unless such non-public information has been previously provided to Buyer) pursuant to an executed confidentiality and standstill agreement (a copy of which confidentiality and standstill agreement shall be promptly (in all events within 24 hours) provided for informational purposes only to Buyer) no less favorable to the Company than the Confidentiality Agreement, but in each case referred to in the foregoing clauses (i) and (ii), only if the Company Board determines in good faith, after consultation with its outside legal counsel and independent financial advisor, that the failure to take such action in connection with such written (and not withdrawn) Takeover Proposal would reasonably be expected to result in the Company Board to be in breach of its fiduciary duties under applicable Legal Requirements (and with such activities to be terminated immediately in connection with any withdrawal of such Takeover Proposal or, in the case of any changes to such Takeover Proposal, if such changes would have not led to such determination had those changes been in effect at the time of the original determination). Nothing contained herein shall prevent the Company Board from disclosing to the Company’s stockholders a position contemplated by Rule 14d-9 and Rule 14e-2(a) promulgated under the Exchange Act with regard to a Takeover Proposal, if the Company determines, after consultation with outside legal counsel, that failure to disclose such position would reasonably be expected to result in a violation of applicable Legal Requirements. If any disclosure or other action pursuant to the preceding sentence of this Section 8.3(b) includes or has the substantive effect of a Company Adverse Recommendation Change, it shall be deemed to be a Company Adverse Recommendation Change (and subject to the obligations with respect thereto) for all purposes under this Agreement.
(c) The Company Board shall not take any of the actions referred to in clauses (i) or (ii) of Section 8.3(b) unless the Company shall have delivered to Buyer a prior written notice advising Buyer that it intends to take such action. The Company shall notify Buyer promptly (but in no event later than 24 hours) after it (or any of its Representatives) receives any Takeover Proposal, any inquiry that could reasonably be expected to lead to a Takeover Proposal, or any request for non-public information relating to the Company or for access to the business, properties, assets, books, or records of the Company by any third party. In such notice, the Company shall identify the third party making, and details of the material terms and conditions of  (along with the latest draft of the proposed Takeover Proposal agreement and all other related documents with respect to such Takeover Proposal), any such Takeover Proposal, indication or request. The Company shall keep Buyer fully informed, on a current basis (and in any event with material updates within twenty-four (24) hours), of the status and material terms of any such Takeover Proposal, indication or request, including any material amendments or proposed amendments as to price and other material terms thereof. The Company shall provide Buyer with at least 48 hours prior notice of any meeting of the Company Board (or such lesser notice as is provided to the members of the Company Board, but in no event less than 24 hours prior notice) at which the Company Board is reasonably expected to consider any Takeover Proposal. The Company shall promptly provide Buyer with a list of any non-public information concerning the Company’s business, present or future performance, financial condition, or results of operations, provided to any third party, and, to the extent such information has not been previously provided to Buyer, copies of such information.
(d) Except as expressly permitted by this Section 8.3(d), the Company Board shall not effect a Company Adverse Recommendation Change or enter into a Company Acquisition Agreement. At any time prior to the receipt of the Requisite Stockholder Approval, subject to the Company having complied with Sections 7.1, 7.2 and 8.3 in all respects, the Company Board may effect a Company Adverse Recommendation Change or enter into a Company Acquisition Agreement, if: (i) the Company promptly notifies Buyer, in writing, at least five Business Days (the “Superior Proposal Notice Period”) before making a Company Adverse Recommendation Change or entering into a Company Acquisition Agreement, of its intention to take such action with respect to a Superior Proposal, which notice shall state expressly that the Company has received a Takeover Proposal that the Company Board intends to declare a Superior Proposal and that the Company Board intends to effect a Company Adverse Recommendation Change and/or the Company intends to enter into a Company Acquisition Agreement; (ii) the Company attaches to such notice the most current version of
A-42

TABLE OF CONTENTS
the proposed agreement and any related documents (which version(s) shall be updated on a prompt basis) and the identity of the third party making such Superior Proposal; (iii) the Company shall, and shall cause its Representatives to, during the Superior Proposal Notice Period, negotiate with Buyer in good faith to make such adjustments in the terms and conditions of this Agreement so that such Takeover Proposal ceases to constitute a Superior Proposal (taking into account any termination fee and expense reimbursement provisions applicable, including the Termination Fee), if Buyer, in its discretion, proposes to make such adjustments (it being agreed that in the event that, after commencement of the Superior Proposal Notice Period, there is any material revision to the terms of a Superior Proposal, including any revision in price, the Superior Proposal Notice Period shall be extended, if applicable, to ensure that at least five Business Days remain in the Superior Proposal Notice Period subsequent to the time the Company notifies Buyer of any such material revision (it being understood that there may be multiple extensions)); (iv) the Company Board determines in good faith, after consulting with its outside legal counsel and independent financial advisor, that such Takeover Proposal continues to constitute a Superior Proposal after taking into account any adjustments made by Buyer during the Superior Proposal Notice Period in the terms and conditions of this Agreement; and (v) prior to or simultaneously with entering into any Company Acquisition Agreement, the Company shall have terminated this Agreement in accordance with Section 9.5(b) and paid the Termination Fee to Buyer.
Section 8.4 Further Action.

(b) To the extent that the execution or delivery by the Company of this Agreement or any of the Ancillary Agreements, or the performance by the Company of its obligations under this Agreement or any of the Ancillary Agreements, or the consummation of the Stock Purchase Transaction, the Merger or any other transaction contemplated hereby or thereby causes or would cause a breach of any Company Contract, permit or right or gives any Person other than the Company the ability to terminate any such Company Contract, permit or right, the Company shall use reasonable commercial efforts to obtain as promptly as practicable the consent of any Third Parties required to prevent or cure such breach or termination.
Section 8.5 Regulatory and Other Authorizations.
(a) Subject to the following sentence with respect to filings under the HSR Act, the Company and Buyer will (i) use their reasonable best efforts to obtain as promptly as reasonably practicable all authorizations, consents, orders, actions and approvals, and to make all filings with and to give all notices to all Governmental Authorities required to consummate the transactions contemplated by this Agreement, (ii) cooperate fully with the other parties hereto in promptly seeking to obtain all such authorizations, consents, orders, actions and approvals and to make all such filings and give such notices and (iii) provide such other information to any Governmental Authority as such Governmental Authority may reasonably request in connection therewith. Following the First Stage Closing, each party hereto agrees to make, upon the earlier of  (A) January 1, 2021, and (B) the satisfaction of the conditions set forth in Section 10.3(a), any required filings under the HSR Act with respect to the Merger Transaction and to supply as promptly as reasonably practicable to the appropriate Governmental Authorities any information and documentary material that may be reasonably requested in connection with such HSR Act filings.

The Company will pay all fees or make other payments provided for under Legal Requirements to any Governmental Authority in order to obtain any such authorizations, consents, orders or approvals.

(c) The Company and Buyer will each promptly notify the other party of any communication that it or any of its Affiliates receives from any Governmental Authority relating to the matters that are the subject of this Agreement and permit, when practicable, the other party to review in advance any proposed communication by such party (or the Company) to any Governmental Authority. Neither the Company nor Buyer will agree to participate in any meeting with any Governmental Authority in respect of any filings, investigation (including any settlement of the investigation), litigation, or other inquiry until it consults with the other party in advance and, to the extent permitted by such Governmental Authority, gives the other party the opportunity to attend and participate at such meeting. The Company and Buyer will coordinate and cooperate fully with each other in exchanging such information and providing such assistance as the other party may reasonably request in connection with the foregoing and in seeking early termination of any applicable waiting periods, including under the HSR Act. The Company and Buyer will provide each other with copies of all correspondence, filings or communications between them or any of their representatives, on the one hand, and any Governmental Authority or members of its staff, on the other hand, with respect to this Agreement and the transactions contemplated by this Agreement; provided, however, that materials may be redacted (w) to remove references concerning the valuation of the Common Shares or the business of the Company, (x) as necessary to comply with contractual arrangements, (y) as necessary to address reasonable privilege or confidentiality concerns and (z) as necessary to address competitive or regulatory concerns; however, both parties shall assess on a case-by-case basis in good faith whether the redacted information may be exchanged between outside competition counsel for the purpose of any merger control proceedings.

(b) For six years after the Merger Effective Time, to the fullest extent permitted under applicable law, Buyer and the Surviving Corporation (the “Indemnifying Parties”) shall indemnify, defend, and hold harmless each Indemnified Party against all losses, claims, damages, liabilities, fees, expenses, judgments, and fines arising in whole or in part out of actions or omissions in their capacity as such occurring at or prior to the Merger Effective Time (including in connection with the transactions contemplated by this Agreement), and shall reimburse each Indemnified Party for any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any such losses, claims, damages, liabilities, fees, expenses, judgments, and fines as such expenses are incurred, subject to the Surviving Corporation’s receipt of an undertaking by such Indemnified Party to repay such legal and other fees and expenses paid in advance if it is ultimately determined in a final and non-appealable judgment of a court of competent jurisdiction that such Indemnified Party is not entitled to be indemnified under applicable Legal Requirements; provided, however, that the Surviving Corporation will not be liable for any settlement effected without the Surviving Corporation’s prior written consent (which consent shall not be unreasonably withheld, conditioned, or delayed).
(c) The Surviving Corporation shall, and Buyer shall cause the Surviving Corporation to: (i) maintain in effect for a period of six years after the Merger Effective Time, if available, the current policies of directors’ and officers’ liability insurance maintained by the Company immediately prior to the Merger Effective Time (provided, that the Surviving Corporation may substitute therefor policies, of at least the same coverage and amounts and containing terms and conditions that are not less advantageous to the directors and officers of the Company when compared to the insurance maintained by the Company as of the date hereof); or (ii) obtain as of the Merger Effective Time “tail” insurance policies with a claims period of six years from the Merger Effective Time with at least the same coverage and amounts and containing terms and conditions that are not less advantageous to the directors and officers of the Company, in each case with respect to claims arising out of or relating to events which occurred before or at the Merger Effective Time (including in connection with the transactions contemplated by this Agreement); provided, however, that in no event will the Surviving Corporation be required to expend an annual premium for such coverage in excess of 200 percent of the last annual premium paid by the Company for such insurance prior to the Signing Date, which amount is determined in accordance with Schedule 8.9 (the “Maximum Premium”). If such insurance coverage cannot be obtained at an annual premium equal to or less than the Maximum Premium, the Surviving Corporation will obtain, and Buyer will cause the Surviving Corporation to obtain, that amount of directors’ and officers’ insurance (or “tail” coverage) obtainable for an annual premium equal to the Maximum Premium.
(d) The obligations of Buyer and the Surviving Corporation under this Section 8.9 shall survive the consummation of the Merger and shall not be terminated or modified in such a manner as to adversely affect any Indemnified Party to whom this Section 8.9 applies without the consent of such affected Indemnified Party (it being expressly agreed that the Indemnified Parties to whom this Section 8.9 applies shall be third party beneficiaries of this Section 8.9, each of whom may enforce the provisions of this Section 8.9).

(d) This Agreement may be terminated by Buyer at any time prior to the First Stage Closing if there shall have been a breach of any representation, warranty, covenant, or agreement on the part of the Company set forth in this Agreement such that the conditions to the First Stage Closing set forth in Section 9.3(b) or Section 9.3(c), as applicable, would not be satisfied and, in either such case, such breach is incapable of being cured by June 30, 2019; provided that Buyer shall have given the Company at least 30 days written notice prior to such termination stating Buyer’s intention to terminate this Agreement pursuant to this Section 9.5(d); provided further, that Buyer shall not have the right to terminate this Agreement pursuant to this Section 9.5(d) if Buyer or Merger Sub is then in material breach of any representation, warranty, covenant, or obligation hereunder, which breach has not been cured.

In the event that this Agreement is terminated and a bona fide Takeover Proposal shall have been publicly disclosed or privately made to the Company Board after the date hereof and not clearly withdrawn or terminated in good faith prior to the Company Stockholder Meeting (in the case of termination pursuant to Section 9.5(a)(3)), prior to the termination date (in the case of termination
A-51

TABLE OF CONTENTS
pursuant to Section 9.5(a)(1)) or prior to the breach giving rise to the right of termination (in the case of termination pursuant to Section 9.5(d)) then, in any case, the Company shall pay to Buyer the Termination Fee within two (2) Business Days of such termination. In the event that this Agreement is terminated and within 12 months of the date this Agreement is terminated, the Company enters into a definitive agreement with respect to any Takeover Proposal or consummates the transactions contemplated by any Takeover Proposal (provided that for purposes of this sentence, the references to “15%” in the definition of Takeover Proposal shall be deemed to be references to “50%”), then the Company shall pay to Buyer the Termination Fee on the date of entry into such agreement or, if earlier, consummation of such Takeover Proposal.
(b) In the event that this Agreement is terminated by Buyer solely pursuant to Section 9.5(a)(3), then the Company shall reimburse Buyer for up to $500,000 in Buyer’s and its Affiliates’ documented aggregate out-of-pocket costs, fees and expenses incurred in connection with the Transactions (including the fees of outside counsel and other advisors, and whether incurred before or after the date of this Agreement and including costs, fees and expenses incurred in connection with the investigation, structuring, negotiation, due diligence, and financial, operating, legal and other analysis with respect to the Transactions); provided, that any such amounts paid by the Company pursuant to this Section 9.6(b) shall be deducted from any Termination Fee that may subsequently become payable pursuant to Section 9.6(a) above.
(c) In the event that this Agreement is terminated by Buyer pursuant to Section 9.5(c), then the Company shall pay to Buyer the Termination Fee within two (2) Business Days of such termination.

(e) Notwithstanding the foregoing, in no event shall the Company be required to pay the fee referred to in this Section 9.6(a) on more than one occasion. Notwithstanding anything to the contrary in this Agreement, the parties agree that the payment of the Termination Fee shall be the sole and exclusive remedy available to Buyer and Merger Sub with respect to this Agreement and the Transactions in the event any such payment becomes due and payable and is paid, and, upon payment of the Termination Fee, the Company (and the Company’s Affiliates and its and their respective Representatives) shall have no further liability to Buyer and Merger Sub under this Agreement; provided, however, that the Company shall not be relieved or released from any liabilities or damages arising out of its willful and material breach of Section 7.1, Section 7.2 or Section 8.3; provided, further, that the aggregate amount of damages determined by a court to be payable by the Company pursuant to the foregoing proviso shall be reduced by the amount of any Termination Fee paid to Buyer pursuant to this Section 9.6.
(f) The parties acknowledge that the agreements contained in this Section 9.6 are an integral part of the transactions contemplated by this Agreement and constitute liquidated damages and not a penalty, and that, without these agreements, the parties would not have entered into this Agreement. Any amount that becomes payable pursuant to Section 9.6 shall be paid by wire transfer of immediately available funds to an account designated by Buyer in writing and shall be reduced by any amounts required to be deducted or withheld therefrom under applicable Legal Requirement in respect of Taxes.

WHEREAS, the parties have agreed that Buyer would receive certain rights, including with respect to the appointment of directors to the board of directors of the Company (the “Board of Directors”), as set forth herein;
NOW, THEREFORE, in consideration of the foregoing and the respective representations and warranties, covenants and agreements set forth in this Agreement, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, effective as of the First Stage Closing (as defined in the SPMA) (the “Effective Date”) the parties hereto agree as follows:
1. Definitions.   Capitalized terms used but not defined in this Agreement shall have the respective meanings ascribed to them in the SPMA.
For purposes of this Agreement:
Transfer” means to, directly or indirectly, offer, sell, transfer, assign, pledge, lend, grant as a gift, encumber, hypothecate or otherwise dispose of, either voluntarily or involuntarily, or to enter into any contract, option or other arrangement or understanding with respect to the sale, transfer, assignment, pledge, loan, gift, encumbrance, hypothecation or other disposition. A Transfer shall include any transaction that, in whole or in part, transfers any economic consequences of ownership.
2. Board of Directors; Working Committee; Access; Notices.
(a) At the First Stage Closing, and thereafter, at any time that Buyer Beneficially Owns at least 75% of the Common Shares acquired by Buyer at the time of the First Stage Closing, Buyer shall have the right to nominate three members to the Board of Directors pursuant to this Section 2 (the “Buyer Directors”), initially at the First Stage Closing, and thereafter at every annual meeting of the stockholders of the Company in which directors are generally elected, including at every adjournment or postponement thereof, and on any action by written consent of the stockholders of the Company relating to the election of directors generally. At least one of the Buyer Directors shall be “Independent” as determined by the Board of Directors (the “Independent Buyer Director”) pursuant to Rule 5605 of The Nasdaq Stock Market (“Nasdaq”) and the rules and regulations of the SEC.
(b) The following procedures shall be followed with respect to the nomination of Buyer Directors pursuant to Section 2(a):
(i) For purposes of whether Buyer has a right to nominate a Buyer Director pursuant to Section 2(a), the Beneficial Ownership of the Common Shares will be initially measured as of the First Stage Closing and thereafter as of the record date for such annual meeting or written consent.
(ii) At least 20 days prior to the First Stage Closing, Buyer shall provide the Company with the identity of the initial Buyer Directors to be appointed to the Board of Directors as of the First Stage Closing (provided that Buyer may substitute such appointees by notice to the Company at least 20 days prior to the First Stage Closing).

TABLE OF CONTENTS
nominees (other than the initial Buyer Directors), at least 90 days prior to the Company’s annual meeting of stockholders, Buyer shall provide the Company with the Buyer’s nominees for the Buyer Directors, along with any other information reasonably requested by the Independent Directors to evaluate the suitability of such candidates for directorship. With respect to any Buyer nominee, Buyer shall use its commercially reasonable efforts to ensure that any such nominee satisfies all Nasdaq and SEC criteria and guidelines for director nominees of the Company other than relevant independence criteria with respect to the Buyer Directors (except the Independent Buyer Director).
(iii) Within 10 days (or 5 days for the initial Buyer Directors) of receiving the Buyer’s nominees for the Buyer Directors in accordance with Section 2(b)(ii), the independent directors of the Company pursuant to Rule 5605 of Nasdaq and the rules and regulations of the SEC (“Independent Directors”) shall make a good faith and reasonable determination as to the suitability of the Buyer’s nominees for Buyer Directors and shall notify Buyer of its determination, it being understood and agreed that the Independent Directors shall not object to a Buyer Director nomination except for the reasons specified in the last sentence of this Section 2(b)(iii) or if the Board of Directors determined that the person proposed by Buyer to be the Independent Buyer Director is not “Independent” pursuant to Rule 5605 of Nasdaq and the rules and regulations of the SEC (such determination by the Board of Directors shall be included in the Independent Directors’ notice to Buyer pursuant to this sentence). If the Independent Directors do not notify Buyer of their determination within the 10 day (or 5 day, if applicable) period specified in the immediately preceding sentence, then Buyer’s nominees shall be deemed to be approved for purposes of Section 2(b)(iv) below. Subject to compliance with the terms of this Agreement, if Buyer and the Independent Directors do not agree on the nominee(s) within 30 days (or 15 days for the initial Buyer Directors) after the Independent Directors raise an objection to a Buyer Director nomination as specified in this Section 2(b)(iii) above, the Buyer Director(s) shall not be nominated by the Company at such annual meeting. The Independent Directors may disqualify a nominee for the following: (i) commission of acts of misrepresentation, fraud, or dishonesty, (ii) commission of or pleading nolo contendere or guilty to, a crime involving fraud, any regulatory violation, dishonesty or any felony, (iii) the entry of an order of the SEC or other regulatory or self-regulatory body against the nominee; or (iv) if the nominee is considered to be a “Bad Actor” as defined in Rule 506 under the Securities Act.
(iv) If the Independent Directors or any authorized committee thereof approves of Buyer’s nominees for Buyer Directors, the Board of Directors shall (1) in the case of the initial Buyer Directors, appoint the Buyer Directors as members of the Board of Directors effective as of the First Stage Closing to serve until the Company’s next annual meeting of stockholders at which directors will be generally elected, (2) in the case of subsequent Buyer Directors, nominate such nominees to be elected as directors and recommend that the stockholders vote to elect such nominees at the next annual meeting of stockholders at which directors will be generally elected and (3) in the case of Buyer Directors designated by Buyer pursuant to Section 2(b)(v) or 2(b)(vi), appoint the Buyer Directors as members of the Board of Directors promptly to serve until the Company’s next annual meeting of stockholders at which directors will be generally elected.
(v) If Buyer nominee(s) is not appointed, nominated or elected by the stockholders, then as soon as practicable after the First Stage Closing or annual meeting, as applicable, Buyer shall designate nominee(s) for such Buyer Director(s) (subject to the limitations on the Independent Directors’ ability to raise an objection as specified in clause (iii) of this Section 2(b)), which nominee(s) shall be appointed as director(s) by the Board of Directors promptly after such designation.
(vi) In the event a Buyer Director resigns from the Board of Directors (or is otherwise incapable of serving on the Board of Directors), the remaining Buyer Directors shall have the power to fill such vacancy. So long as the Buyer Director replacement satisfies the criteria in Sections 2(b)(ii) and 2(b)(iii), the Board of Directors shall vote in favor of such Buyer Director replacement.
(c) Each of the Buyer Directors will be governed by the same protections and obligations as all other directors of the Company, including, without limitation, protections and obligations regarding

Each Buyer Director agrees that he or she shall be bound by the Company’s insider trading policy. The Company shall use commercially reasonable efforts to ensure that the Buyer Directors are covered by liability insurance for directors with coverage that is at least as favorable, in the aggregate, to such directors as the coverage provided for by insurance policies acquired by the Company for the benefit of directors of the Company as in effect as of the date of this Agreement (it being agreed that the Company shall be required to obtain such coverage to the extent that the cost therefor does not exceed, on a per director basis, more than 200% of the premium for the coverage that is in effect as of the date hereof). Fortress shall use commercially reasonable efforts to ensure that the Buyer Directors are covered by liability insurance for directors with coverage that is at least as favorable, in the aggregate, to such directors as the coverage provided for by insurance policies acquired by Fortress for the benefit of directors of the Company as in effect as of the date of this Agreement (it being agreed that Fortress shall be required to obtain such coverage to the extent that the cost therefor does not exceed, on a per director basis, more than 200% of the premium for the coverage that is in effect as of the date hereof).
(d) The Board of Directors shall have seven directors and the size of the Board of Directors may only be increased or decreased if Buyer consents.
(e) Buyer Directors shall be as close as proportionally practicable, but at least one Buyer Director shall be, represented on all committees of the Board of Directors and shall be appointed to such committees in accordance with Nasdaq and SEC rules. The chair of the Company’s audit committee shall be selected by Buyer out of the Buyer Directors; provided that such person qualifies as an “audit committee financial expert” as such term is defined in Item 407(d)(5)(ii) of Regulation S-K under the Securities Act.
(f) Except for the Independent Buyer Director, the Buyer Directors shall not be compensated for their service on the Board of Directors. The compensation of the Independent Buyer Director shall be equal to the compensation paid to the other Independent Directors of the Company. No member of the Board of Directors designated by or Affiliated with Fortress shall be compensated for his or her service on the Board of Directors, except to the extent such person is “Independent” as determined by the Board of Directors pursuant to Rule 5605 of Nasdaq and the rules and regulations of the SEC.
(g) At the First Stage Closing, and thereafter, at any time that Buyer Beneficially Owns at least 75% of the Common Shares acquired by Buyer at the time of the First Stage Closing, Buyer shall have the right to appoint one representative (the “Buyer Representative”) to the Working Committee (as defined in Section 11.1 of the Revogenex License) and the Company shall cooperate with Buyer to promptly cause such appointment. Buyer shall have the right to replace any person appointed by it as a Buyer Representative with another person to act in such capacity.
(h) From the termination of the SPMA pursuant to Section 10.5(a) thereof and as long as Buyer Beneficially Owns at least 75% of the Common Shares acquired by Buyer at the time of the First Stage Closing, the Company shall provide Buyer with all the rights afforded to Buyer in Section 8.2 of the SPMA as if such rights are set forth herein.
(i) In order for Buyer or its Affiliates to comply with Legal Requirements or the requirements of any stock exchange on which the securities of such a Person is listed, from the date of this Agreement until the Second Stage Closing, (i) if any action taken at a Company Board meeting (or by written consent of the Company Board) or a Company stockholders meeting (or by written consent of the Company’s stockholders) would be required to be disclosed by the Company to the SEC, the Company shall, concurrently with calling such a meeting, or immediately prior to taking such action by written consent, as applicable, notify Buyer of such proposed action, (ii) if any other action or event occurs which would be required to be disclosed by the Company to the SEC, the Company shall, within one Business Day prior to taking such action (or in case such action is not taken by the Company or in case of any other event, within one Business Day of becoming aware of such action or event) notify Buyer of such action or event and (iii) if the Company makes any disclosure to the SEC, the Company shall, concurrently with such disclosure, notify Buyer thereof, including a copy of such disclosure.

3. Tag Along Rights; Restriction on Transfer.
(a) If at any time a Stockholder or any of its Affiliates, assigns, successors, transferees or heirs (in each case, by operation of law or otherwise) (the “Selling Stockholder”) proposes to Transfer any shares of its capital stock of the Company (“Tag-along Shares”) to a third party purchaser (the “Proposed Transferee”), Buyer shall be permitted to participate in such Transfer (a “Tag-along Sale”) on the terms and conditions set forth in this Section 3.
(b) Prior to the consummation of any such Transfer of Tag-along Shares described in Section 3(a), the Selling Stockholder shall deliver to the Company and Buyer a written notice (a “Sale Notice”) of the proposed Tag-along Sale subject to this Section 3 no later than 30 Business Days prior to the closing date of the Tag-along Sale. The Sale Notice shall make reference to Buyer’s rights hereunder and shall describe in reasonable detail:

(v) a copy of any form of agreement proposed to be executed in connection therewith.
(c) The Sale Notice shall include, and shall constitute, an offer for Buyer to sell the shares described therein in accordance with this Section 3 to the Proposed Transferee.

The offer to Buyer set forth in a Sale Notice shall be irrevocable, and, to the extent such offer is accepted in a Tag-along Notice, Buyer shall be bound and obligated to Transfer in the Tag-along Sale on the terms and conditions set forth in this Section 3. If Buyer delivers a Tag-along Notice in compliance with this Section 3(c) within the Tag-along Period, Buyer shall have the right to Transfer to the Proposed Transferee up to the number of shares of capital stock of the Company equal to the product of  (x) Buyer’s Percentage Interest (as defined below) and (y) the aggregate number of shares of capital stock of the Company the Proposed Transferee proposes to buy as stated in the Sale Notice. For purposes of this Section 3, Buyer’s “Percentage Interest” means a fraction the numerator of which is equal to the number of shares of capital stock of the Company, on an as-converted basis, then held by Buyer and the denominator of which is equal to the number of shares of capital stock of the Company, on an as-converted basis, then held by the Selling Stockholder and Buyer in the aggregate.
(d) If Buyer participates in a Transfer pursuant to this Section 3, Buyer shall receive the same consideration per share as the Selling Stockholder (regardless of class or type of capital stock of the Company being sold in such Transfer by either Buyer or the Selling Stockholder). The Selling Stockholder and Buyer shall each be solely responsible for their expenses incurred with regard to their participation in a Tag-along Sale.
(e) Buyer shall make or provide representations, warranties, covenants, indemnities and agreements that are not less favorable to Buyer than those made or provided by the Selling Stockholder in connection with the Tag-along Sale (except that in the case of representations, warranties, covenants, indemnities and agreements pertaining specifically to the Selling Stockholder, Buyer shall make the comparable representations, warranties, covenants, indemnities and agreements pertaining specifically to itself); provided, that any indemnification obligation of Buyer in respect of breaches of representations and warranties shall be pro rata based on the consideration received by Buyer and shall be in an amount not to exceed the aggregate proceeds received by Buyer (net of taxes) in connection

(f) Buyer shall take all actions as may be reasonably necessary to consummate the Tag-along Sale, including entering into agreements and delivering certificates and instruments, consistent with the agreements being entered into and the certificates being delivered by the Selling Stockholder; provided that any such agreements, certificates and instruments contain substantially the same terms and conditions as those executed by the Selling Stockholder as applied in a nondiscriminatory manner based on Buyer’s Percentage Interest.
(g) If Buyer does not deliver a Tag-along Notice in compliance with Section 3(c) above within the Tag-along Period, the Selling Stockholder shall have 90 days following the expiration of the Tag-along Period in which to Transfer the Tag-along Shares described in the Sale Notice, at a per share price that is no greater than the per share price set forth in the Sale Notice and on other terms and conditions which are not more favorable to the Selling Stockholder than those set forth in the Sale Notice. If at the end of such 90 day period, the Selling Stockholder has not completed such Transfer, the Selling Stockholder may not then effect a Transfer of Tag-along Shares subject to this Section 3 without again fully complying with the provisions of this Section 3.
(h) Without limiting the provisions of this Section 3, the Stockholders hereby agree that they and their Affiliates shall not Transfer any capital stock of the Company to a competitor of Buyer or its Affiliates.

WHEREAS, the Lender has agreed to extend credit to the Borrower in an aggregate amount not to exceed $3,000,000 upon the terms and conditions set forth herein.
NOW, THEREFORE, in consideration of the premises and the agreements, provisions and covenants herein contained, the parties hereto agree as follows:
1. Loans.
(a) Subject to the satisfaction or waiver of the conditions precedent set forth in Section 4 below, commencing on or after the date hereof and at any time five (5) Business Days prior to the Maturity Date (as defined below), the Borrower may borrow, and the Lender hereby commits to lend (any such loans extended hereunder, a “Loan”), an aggregate principal amount of up to Three Million Dollars ($3,000,000) by providing written notice to the Lender no less than five (5) Business Days prior to the date of the borrowing, which notice shall include (x) the amount of such borrowing, (y) the date of such borrowing and (z) a description of the intended use of the proceeds of such borrowing that demonstrates that such use is in accordance with the Borrower’s Business Plan and Budget attached as Schedule 2.1 of the SPMA (the “Budget”); provided, that, each such borrowing shall be in a minimum principal amount of  $500,000 or any larger multiple of  $100,000. The Lender’s commitment under this Section 1(a) shall terminate immediately and without further action (i) upon the making of any Loan on the date thereof in respect of the amount thereof and (ii) in its entirety five (5) Business Days prior to the Maturity Date. Any amount of the Loans that is subsequently repaid or prepaid may not be reborrowed. The proceeds of the Loans shall solely be applied by the Borrower in accordance with the Budget.
(b) The Lender is authorized to maintain a register (the “Register”) to record the date and amount of Loans made by the Lender from time to time, the amount of interest accruing from time to time and the date and amount of each payment or prepayment of principal thereof, and any such recordation shall constitute presumptive evidence of the accuracy of the information so recorded. The Register shall include the name and address of the Lender, and any transfer of a Loan shall not be effective unless recorded in the Register.
2. Interest.
(a) The outstanding principal amount of the Loans shall bear interest from the date of the applicable borrowing at the rate per annum of seven percent (7%), compounded quarterly on the last day of each fiscal quarter. Interest shall be calculated on the basis of a year comprised of 360 days for the actual number of days elapsed.
(b) Accrued and unpaid interest on the Loans shall be payable on the last day of each fiscal quarter; provided, that if such date is not a Business Day, interest shall be payable on the next succeeding Business Day.

3. Repayment of Loan.
(a) The Borrower hereby unconditionally promises to pay to the Lender, in lawful money of the United States of America and in immediately available funds, the full outstanding principal amount of all the Loans, together with accrued and unpaid interest thereon, no later than the earlier of  (i) the First Stage Closing Date and (ii) the date that is 30 days following the termination of the SPMA (such earlier date, the “Maturity Date”).
(b) (i) Voluntary prepayments of the outstanding principal amount of the Loans, or interest accruing thereon, and (ii) voluntary reductions in the commitment of the Lender to make Loans in accordance herewith through the Maturity Date, shall be permitted at any time, on not less than three (3) Business Days’ prior written notice to the Lender, and from time to time without premium or penalty.

If required by such a Governmental Authority, the Borrower shall pay any such taxes, impositions or tariffs directly to such Governmental Authority and at the Lender’s request shall provide satisfactory proof to the Lender of such payment. The Borrower shall indemnify the Lender for and hold it harmless against the full amount of taxes or similar impositions of tariffs, other than United States Federal and applicable state income taxes payable by the Lender, imposed on or paid by the Lender or any affiliate of the Lender in respect of any liability (including, without limitation, any taxes or tariffs imposed or asserted by any Governmental Authority on amounts payable under this Section 3(c), and penalties, interest and expenses) arising therefrom or with respect thereto. This indemnification shall be made within ten (10) Business Days from the date the Lender makes written demand therefor.

(n) Headings.   Section headings used herein are for convenience of reference only, are not part of this Agreement and shall not affect the construction of, or be taken into consideration in interpreting, this Agreement.

GUARANTY
SECTION 2.1. Guaranty.   Guarantor hereby unconditionally and irrevocably guarantees the full and prompt payment when due, whether at stated maturity, by acceleration or otherwise (including, without limitation, all amounts which would have become due but for the operation of the automatic stay under Section 362(a) of the Bankruptcy Code), of the following (collectively, the “Guaranteed Obligations”):
(a) all obligations of Borrower to the Lender now or hereafter existing under the Credit Agreement, whether for principal, interest, fees, charges, expenses or otherwise; and
(b) any and all costs and expenses (including, without limitation, reasonable fees and expenses of legal counsel and accountants) incurred by the Lender in enforcing any of its rights under this Guaranty.
This Guaranty constitutes a guaranty of payment when due and not merely of collection, and Guarantor specifically agrees that it shall not be necessary or required that the Lender exercise any right, assert any claim or demand or enforce any remedy whatsoever against Borrower or any collateral before or as a condition to the obligations of Guarantor hereunder. Notwithstanding the foregoing, the obligations of Guarantor hereunder shall be limited to a maximum aggregate amount equal to the greatest amount that would not render Guarantor’s obligations hereunder subject to avoidance as a fraudulent transfer or fraudulent conveyance under Section 548 of the Bankruptcy Code or any provisions of applicable state law.
SECTION 2.2. Acceleration of Guaranty.   Guarantor agrees that, if any Event of Default under Section 8 of the Credit Agreement shall occur and be continuing at a time when any of the Guaranteed Obligations are not then due and payable, to the extent not prohibited by applicable Debtor Relief Laws, Guarantor will pay to the Lender forthwith the full amount which would be payable hereunder by Guarantor if all such Guaranteed Obligations were then due and payable.
SECTION 2.3. Guaranty Absolute.   This Guaranty is a continuing, absolute, unconditional and irrevocable guaranty of payment and shall remain in full force and effect until all the Guaranteed Obligations have been indefeasibly paid in full in cash and all commitments under the Credit Agreement shall have permanently terminated. Guarantor guarantees that the Guaranteed Obligations will be paid strictly in accordance with the terms of this Guaranty under which they arise, regardless of any law, regulation or order now or hereafter in effect in any jurisdiction affecting any of such terms or the rights of the Lender with respect thereto. The obligations of Guarantor under this Guaranty are independent of the obligations under the Credit Agreement and a separate action or actions may be brought and prosecuted against Guarantor to enforce this Guaranty, irrespective of whether any action is brought against Borrower or Guarantor or whether Borrower or Guarantor is joined in any such action or actions. The liability of Guarantor under this Guaranty shall be absolute and unconditional irrespective of:
(a) any lack of validity, legality or enforceability of the Credit Agreement, this Guaranty or any other agreement or instrument relating to any of the foregoing;
(b) any change in the time, manner or place of payment of, or in any other term of, all or any of the Guaranteed Obligations, or any compromise, renewal, extension, acceleration or release with respect thereto, or any other amendment or waiver of or any consent to departure from the Credit Agreement or this Guaranty, including any increase in the Guaranteed Obligations resulting from the extension of additional credit to Borrower or otherwise;
(c) any addition, exchange, release, impairment or non-perfection of any collateral, or any release or amendment or waiver of or consent to departure from any other guaranty, for all or any of the Guaranteed Obligations;
A-88

TABLE OF CONTENTS
(d) the failure of the Lender:
(i) to assert any claim or demand or to enforce any right or remedy against Borrower or any other Person (including any other guarantor) under the provisions of the Credit Agreement, this Guaranty or otherwise; or
(ii) to exercise any right or remedy against any other guarantor of, or collateral securing, any of the Guaranteed Obligations;
(e) any amendment to, rescission, waiver, or other modification of, or any consent to departure from, any of the terms of the Credit Agreement or this Guaranty;
(f) any defense, set-off or counterclaim which may at any time be available to or be asserted by Borrower against the Lender, whether in connection with this Guaranty, the transactions contemplated in the Credit Agreement, or any unrelated transaction;
(g) any reduction, limitation, impairment or termination of the Guaranteed Obligations for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to (and Guarantor hereby waives any right to or claim of) any defense or set-off, counterclaim, recoupment or termination whatsoever by reason of the invalidity, illegality, nongenuineness, irregularity, compromise or unenforceability of, or any other event or occurrence affecting, the Guaranteed Obligations or otherwise;
(h) any manner of application of collateral, or proceeds thereof, to all or any of the Guaranteed Obligations, or any manner of sale or other disposition of any collateral for all or any of the Guaranteed Obligations or any other assets of Borrower;
(i) any change, restructuring or termination of the corporate structure or existence of Borrower or Guarantor; or
(j) any other circumstance which might otherwise constitute a defense available to, or a legal or equitable discharge of, Borrower or Guarantor.
SECTION 2.4. Reinstatement, etc.   All payments to be made hereunder by Guarantor shall be made without offset, set-off or deduction of any kind. Guarantor agrees that this Guaranty shall continue to be effective or be reinstated, as the case may be, if at any time any payment (in whole or in part) of any of the Guaranteed Obligations is rescinded or must otherwise be restored by the Lender, upon the insolvency, bankruptcy or reorganization of Borrower, or otherwise, all as though such payment had not been made.
SECTION 2.5. Waiver.   Guarantor hereby waives promptness, diligence, notice of acceptance and any other notice with respect to any of the Guaranteed Obligations and this Guaranty and any requirement that the Lender protect, secure, perfect or insure any lien or any property subject thereto or exhaust any right or take any action against Borrower or any other Person (including any other guarantor) or any collateral securing the Guaranteed Obligations.
SECTION 2.6. Waiver of Subrogation.   Guarantor hereby irrevocably waives any claim or other rights which it may now or hereafter acquire against Borrower that arise from the existence, payment, performance or enforcement of Guarantor’s obligations under this Guaranty or the Credit Agreement, including any right of subrogation, reimbursement, contribution, exoneration or indemnification, any right to participate in any claim or remedy of the Lender against Borrower, Guarantor or any collateral which the Lender now has or hereafter acquires, whether or not such claim, remedy or right arises in equity, or under contract, statute or common law, including the right to take or receive from Borrower or Guarantor, directly or indirectly, in cash or other property or by set-off or in any manner, payment or security on account of such claim or other rights, until such time as the Guaranteed Obligations shall have been indefeasibly paid in full in cash and all commitments under the Credit Agreement shall have permanently terminated. If any amount shall be paid to Guarantor in violation of the preceding sentence, such amount shall be deemed to have been paid to Guarantor for the benefit of, and held in trust for, the Lender, and shall forthwith be paid to the Lender to be credited and applied against the Guaranteed Obligations, whether matured or unmatured. Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by the Credit Agreement and that the waiver set forth in this Section 2.6 is knowingly made in contemplation of such benefits.

A-122

TABLE OF CONTENTS
(c) The execution or delivery by Fortress of this Agreement or the performance by Fortress of its obligations under this Agreement will not (i) result in any breach of any provision of Fortress’ certificate of incorporation or bylaws, as amended, (ii) result in any breach of, require (with or without notice or lapse of time or both) any payment, consent or notice or constitute a default (or give rise to any right of purchase, termination, amendment, acceleration or cancellation) under any Contract or order or judgment to which Fortress is a party or by which it or its assets are bound, (iii) result in the creation of an Encumbrance, or (iv) violate any applicable Legal Requirement, other than, in the case of clauses (ii) through (iv), such breaches, defaults or violations that have not had, or are not reasonably likely to have, a material adverse effect on the ability of Fortress to perform its obligations under or to consummate the transactions contemplated by this Agreement.
4. Remedies.   Buyer and Fortress acknowledge and agree that the remedies at law for any breach by Fortress of any of the covenants or provisions of this Agreement are inadequate, and that Buyer shall be entitled to an injunction, specific performance or other equitable relief against Fortress in the event of any breach, Fortress agrees to reimburse Buyer any and all fees, costs and expenses (including reasonable attorneys’ fees) incurred for purposes of enforcing this Agreement in the event such enforcement is either consented to by Fortress or ordered by a court of competent jurisdiction. Without limiting the foregoing, in the event of a breach or threatened breach by Fortress of the terms of this Agreement, Buyer shall be entitled, if it so elects, to: (a) have the provisions of this Agreement specifically enforced by any court having equity jurisdiction or to enjoin Fortress from any further violation of this Agreement; (b) require Fortress to account for and pay over to Buyer all compensation, profits, monies, accruals, increments or other benefits derived or received by Fortress as the result of any transactions constituting a breach of this Agreement, and Fortress hereby agrees to promptly account for and pay over such benefits to Buyer; and (c) institute legal proceedings to obtain other monetary damages for any such breach.

Each of the rights and remedies enumerated above shall be independent of the others, and shall be severally enforceable, and all of such rights and remedies shall be in addition to, and not in lieu of, any other rights and remedies available to Buyer at law or in equity.
5. Severability.   In the event that any of the covenants or provisions of Section 2 hereof may be determined to be invalid, illegal or unenforceable by a court of competent jurisdiction in a final non-appealable judgment or order as a result of any time or scope (geographic or otherwise) limitations provided therein, Buyer and Fortress expressly agree that such covenants and provisions shall be effective nevertheless for the greatest period of time and within the greatest scope (geographic or otherwise) that would not render them invalid, illegal or unenforceable, and in such event Fortress hereby consents that such provisions may be judicially modified accordingly in any proceeding brought to enforce the provisions of Section 2 hereof. Any other covenant or provision of this Agreement that may be determined to be invalid, illegal or unenforceable shall be ineffective only to the extent of such invalidity, illegality or unenforceability without invalidating or rendering unenforceable any remaining provisions of this Agreement.
6. Tolling Period.   The obligations contained in Section 2 hereof shall be extended by any length of time during which Fortress is or was in breach of any such obligations.
7. Acknowledgments.   Fortress hereby acknowledges and agrees that (a) this Agreement (including the time, scope (geographic or otherwise) or any other limitations provided in Section 2 hereof) is reasonable and necessary for the protection of the immediate interests of Buyer, and that any violation of this Agreement would cause substantial injury to Buyer and that Buyer would not have entered into the SPMA, this Agreement and the other Ancillary Agreements without receiving the additional consideration offered by Fortress in binding itself to this Agreement; (b) the scope of this Agreement, in terms of duration, geographic area, activities restricted and otherwise, is reasonable; and (c) counsel for Fortress has reviewed this Agreement.

To the extent that Buyer has obtained the insurance coverage referred to in Section 11 of the SPMA (the “R&WI”), Buyer shall first use reasonable best efforts to pursue any claims that it could otherwise have brought against Fortress under this Section 2 against the insurer providing the R&WI to the extent such claims are covered by the R&WI, it being agreed that Buyer shall not be limited to exercise its rights under this Section 2 to the extent that (i) there is no R&WI or (ii) the R&WI does not cover Losses indemnifiable under this Section 2 (including due to fraud or intentional misrepresentation), it being further agreed that nothing herein shall preclude any Buyer Indemnified Party from (A) delivering an Indemnification Notice to Fortress (even though Buyer is pursuing the insurer providing the R&WI), (B) pursuing Fortress hereunder if Buyer does not reach an agreement with the insurer providing the R&WI within 30 days of making the claim to such insurer or (C) pursuing Fortress hereunder (without first pursuing the insurer providing the R&WI) within 90 days prior to the Second Stage Closing.
(f) Subject to the other provisions of this Section 2, whenever any claim shall arise for indemnification under this Section 2, the Buyer Indemnified Parties, shall notify Fortress in writing (the “Indemnification Notice”) within 30 days of becoming aware of the claim, which writing shall include the facts reasonably available to the Buyer Indemnified Parties constituting the basis for such claim, the specific section of the SPMA or Ancillary Agreement upon which the claim is based and an estimate, if reasonable practicable, of the amount of Losses asserted (or to be asserted as of the Second Stage Closing giving effect to the Second Stage Closing) against, imposed (or to be imposed as

of the Second Stage Closing giving effect to the Second Stage Closing) upon or sustained (to be sustained as of the Second Stage Closing giving effect to the Second Stage Closing) or incurred (to be incurred as of the Second Stage Closing giving effect to the Second Stage Closing) by the Buyer Indemnified Party; provided, however, that the failure of the Buyer Indemnified Party to provide such notice shall not affect the indemnification obligations of Fortress except to the extent that Fortress is actually materially prejudiced as a result of such failure; provided, further, that, without limiting the provisions of this Agreement, the Buyer Indemnified Parties shall have the right to deliver such Indemnification Notice after the consummation of the First Stage Closing and prior to, or concurrently with, the consummation of the Second Stage Closing with respect to any representation or warranty of the Company contained in the SPMA or any Ancillary Agreement that Buyer in good faith expects will be breached or inaccurate as of the Second Stage Closing Date as if made at and as of such time (except to the extent expressly made as of an earlier date, in which case as of such date). If Fortress does not notify the Buyer Indemnified Party within thirty (30) days following its receipt of an Indemnification Notice that Fortress disputes its liability to the Buyer Indemnified Party hereunder, such claim specified by the Buyer Indemnified Party in such Indemnification Notice shall be conclusively deemed a liability of Fortress hereunder and Fortress shall pay the amount of such liability to the Buyer Indemnified Party on demand. If Fortress agrees that it has an indemnification obligation but asserts that it is obligated to pay a lesser amount than that claimed by the Buyer Indemnified Party, Fortress shall pay such lesser amount promptly to the Buyer Indemnified Party, without prejudice to or waiver of the Buyer Indemnified Party’s claim for the difference. Buyer and Fortress hereby covenant and agree that, to the extent there is a disagreement with respect to a claim for indemnification under this Section 2, they shall negotiate in good faith to arrive at a resolution of such disagreement. Fortress shall pay to the Buyer Indemnified Parties any amount of Losses stated in an Indemnity Determination (as defined below) on demand. “Outstanding Indemnification Amount” means the sum of the amount of Losses stated in all Indemnity Determinations with respect to all indemnification claims by all Buyer Indemnified Parties pursuant to this Agreement to the extent not actually paid by Fortress to the applicable Buyer Indemnified Parties as of the Second Stage Closing.
(g) Subject to the other provisions of this Section 2, upon a determination of an indemnification claim made by the Buyer Indemnified Party, whether such determination is by reason of  (a) the mutual agreement of Fortress and the Buyer Indemnified Party (or deemed to be a liability of Fortress pursuant to Section 2(f)), or (b) a judgment or award of a court of competent jurisdiction (each an “Indemnity Determination”), then the amount of the Losses stated in such Indemnity Determination shall be paid by Fortress in accordance with the terms of this Section 2 (without prejudice to the Buyer Indemnified Parties’ or Fortress’s right to appeal any such decision, provided that such payment obligation shall not be affected by, delayed or stayed by any such pending appeal), it being agreed that Fortress’ obligation to pay any Post-Closing Indemnification Amount or Adjusted Pre-Closing Indemnification Amount shall be limited to the Fortress Portion multiplied by such Post-Closing Indemnification Amount or Adjusted Pre-Closing Indemnification Amount, as applicable.
(h) For purposes of this Agreement, “Fundamental Representations” means (x) the representations and warranties of the Company contained in Section 5.1, Section 5.3, Section 5.4(c), Section 5.5(a), Section 5.5(b), Section 5.5(c), Section 5.8, Section 5.9, Section 5.11, Section 5.14, Section 5.16, Section 5.17 and Section 5.20 of the SPMA and (y) the representations and warranties of the Company contained in any Ancillary Agreement that are substantially similar to the representations and warranties referred to in the foregoing clause (x) of this Section 2(h).
(i) In case of any Proceeding with respect to this Agreement and the rights and obligations arising hereunder, or for recognition and enforcement of any judgment in respect of this Agreement and the rights and obligations arising hereunder, Fortress shall use its reasonable best efforts to expedite the resolution of such Proceeding, and acknowledges and agrees that time is of the essence to the Buyer Indemnified Parties in terms of such resolution.
(j) With respect to any indemnification claim by a Buyer Indemnified Party hereunder that is not subject to an Indemnity Determination prior to the Second Stage Closing, if, after the Second Stage Closing, a court of competent jurisdiction dismisses such indemnification claim on the grounds that it was a frivolous claim, and such dismissal becomes final and not subject to any further appeals or the time for giving notice to take such appeals has lapsed and no such notice was filed, then Buyer shall

reimburse Fortress for its reasonable and documented legal fees and expenses incurred in connection with the defense of such indemnification claim.

TABLE OF CONTENTS
(e) Public Announcements.   Except as required by Legal Requirements or by the requirements of any stock exchange on which the securities of a party hereto or any of its Affiliates are listed, no party to this Agreement will make, or cause to be made, any press release or public announcement in respect of this Agreement or the transactions contemplated hereby or otherwise communicate with any news media with respect to the foregoing without prior notification to the other parties, and the parties to this Agreement will consult with each other and cooperate as to the form, timing and contents of any such press release, public announcement or disclosure.
(f) Severability.   Each provision of this Agreement will be interpreted in such manner as to be effective and valid under applicable Legal Requirements, but if any provision of this Agreement is found to be unenforceable or invalid under applicable Legal Requirements, such provision will be ineffective only to the extent of such unenforceability or invalidity, and the parties will negotiate in good faith to modify this Agreement so that the unenforceable or invalid provision is replaced by such valid and enforceable provision which the parties consider, in good faith, to match as closely as possible the invalid or unenforceable provision and to achieve the same or a similar economic effect and to give effect to the parties’ original intent. The remaining provisions of this Agreement will continue to be binding and in full force and effect.
(g) Assignment.   No party hereto may assign, in whole or in part, or delegate all or any part of its rights, interests or obligations under this Agreement without the prior written consent of the other party. Any assignment or delegation made without such consent will be void. Notwithstanding the foregoing, Buyer shall be entitled to (a) assign its rights under this Agreement to any one of its Affiliates, and (b) assign any or all of its rights and obligations under this Agreement (in whole or in part) as collateral security in a financing transaction.
(h) Confidentiality Agreement.   The terms of the Confidentiality Agreement are hereby incorporated herein by reference and will continue in full force and effect until expiration or termination in accordance with the terms therein.
(i) Governing Law.   This Agreement and any claims or causes of action pursuant to it will be governed by and construed in accordance with the laws of the State of Delaware, without regard for its principles of conflict of laws.
(j) Specific Performance.   Each party acknowledges and agrees that the other party would be irreparably damaged if the provisions of this Agreement are not performed in accordance with their terms and that any breach of this Agreement and the non-consummation of the transactions contemplated hereby by either party could not be adequately compensated in all cases by monetary damages alone. Accordingly, in addition to any remedy to which such other party may be entitled under Section 4(k), provisional measures and injunctive relief necessary to protect the possibility of each party to seek specific performance from the other from the tribunal referred to in Section 4(k) can be sought from any court of competent jurisdiction. Each of the parties hereto (i) agrees that it shall not oppose the granting of any such relief and (ii) hereby irrevocably waives any requirement for the security or posting of any bond in connection with any such relief  (it is understood that clause (i) of this sentence is not intended to, and shall not, preclude any party hereto from litigating on the merits the substantive claim to which such remedy relates).
(k) Submission to Jurisdiction.   Each of the parties hereto irrevocably agrees that any Proceeding with respect to this Agreement and the rights and obligations arising hereunder, or for recognition and enforcement of any judgment in respect of this Agreement and the rights and obligations arising hereunder brought by any other party hereto or its successors or assigns, shall be brought and determined exclusively in the Court of Chancery of the State of Delaware, or in the event (but only in the event) that such court does not have subject matter jurisdiction over such action or proceeding, in the federal courts sitting in the State of Delaware. Each of the parties hereto agrees that mailing of process or other papers in connection with any such action or proceeding in the manner provided in Section 4(d), or in such other manner as may be permitted by applicable Legal Requirements, will be valid and sufficient service thereof. Each of the parties hereto hereby irrevocably submits with regard to any such action or proceeding for itself and in respect of its property, generally and unconditionally, to the personal jurisdiction of the aforesaid courts and agrees that it will not bring any action relating
A-136

TABLE OF CONTENTS
to this Agreement or any of the transactions contemplated by this Agreement in any court or tribunal other than the aforesaid courts. Each of the parties hereto hereby irrevocably waives, and agrees not to assert, by way of motion, as a defense, counterclaim, or otherwise, in any action or proceeding with respect to this Agreement and the rights and obligations arising hereunder, or for recognition and enforcement of any judgment in respect of this Agreement and the rights and obligations arising hereunder: (a) any claim that it is not personally subject to the jurisdiction of the above named courts for any reason other than the failure to serve process in accordance with this Section 4(k); (b) any claim that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise); and (c) to the fullest extent permitted by the applicable Legal Requirements, any claim that (i) the suit, action or proceeding in such court is brought in an inconvenient forum, (ii) the venue of such suit, action or proceeding is improper, or (iii) this Agreement, or the subject matter hereof, may not be enforced in or by such courts.
(l) Waiver of Jury Trial.   EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES AND, THEREFORE, EACH SUCH PARTY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LEGAL ACTION ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. EACH PARTY TO THIS AGREEMENT CERTIFIES AND ACKNOWLEDGES THAT: (A) NO REPRESENTATIVE OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT SEEK TO ENFORCE THE FOREGOING WAIVER IN THE EVENT OF A LEGAL ACTION; (B) SUCH PARTY HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER; (C) SUCH PARTY MAKES THIS WAIVER VOLUNTARILY; AND (D) SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 4(l).
(m) Waiver.   Any term or condition of this Agreement may be waived at any time by the party that is entitled to the benefit thereof, but no such waiver shall be effective unless set forth in a written instrument duly executed by or on behalf of the party waiving such term or condition, and no waiver by any party of any default, misrepresentation, or breach of warranty or covenant hereunder, shall be deemed to extend to any prior or subsequent default, misrepresentation, or breach of warranty, covenant or agreement hereunder or affect in any way any rights arising by virtue of any such prior or subsequent occurrence. No failure or delay of any party in exercising any right or remedy hereunder shall operate as a waiver thereof, and no waiver by any party of any term or condition of this Agreement, in any one or more instances, shall be deemed to be or construed as a waiver of the same or any other term or condition of this Agreement on any future occasion.
(n) Counterparts; Facsimile Signature.   This Agreement may be executed in one (1) or more counterparts, by original or facsimile (or other such electronically transmitted) signature, each of which will be deemed an original, but all of which will constitute one and the same instrument. A party executing this Agreement by facsimile (or other such electronically transmitted) signature shall, upon request from another party, promptly deliver to the requesting party an original counterpart of such signature.
(o) Rights Cumulative.   All rights and remedies of each of the parties under this Agreement will be cumulative, and the exercise of one or more rights or remedies will not preclude the exercise of any other right or remedy available under this Agreement or applicable Legal Requirements.
(p) Interpretation.    (a) The words “hereof”, “herein”, and “hereunder” and words of similar import, when used in this Agreement, shall refer to this Agreement as a whole and not to any particular provision of this Agreement; (b) the words “date hereof”, when used in this Agreement, shall refer to the date set forth in the Preamble; (c) the terms defined in the singular have a comparable meaning when used in the plural, and vice versa; (d) the terms defined in the present tense have a
A-137

TABLE OF CONTENTS
comparable meaning when used in the past tense, and vice versa; (e) any references herein to a specific Section or Article shall refer, respectively, to Sections or Articles of this Agreement; (f) wherever the word “include”, “includes”, or “including” is used in this Agreement, it shall be deemed to be followed by the words “without limitation”; (g) references herein to any gender includes each other gender; (h) the word “or” shall not be exclusive; (i) the headings herein are for convenience of reference only, do not constitute part of this Agreement and shall not be deemed to limit or otherwise affect any of the provisions hereof; (j) any references herein to any Governmental Authority shall be deemed to also be a reference to any successor Governmental Authority thereto; and (k) the parties hereto have participated jointly in the negotiation and drafting of this Agreement and, in the event that an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as jointly drafted by the parties hereto and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provision of this Agreement.
(q) Effectiveness.   This Agreement shall become effective as of the Effective Date. If the SPMA is terminated in accordance with its terms prior to the First Stage Closing, this Agreement shall automatically terminate. This Agreement shall automatically terminate upon the Second Stage Closing. Notwithstanding the preceding two sentences, this Section 4 shall survive any termination of this Agreement and any breach hereof prior to such termination shall survive such termination. Notwithstanding anything herein to the contrary, the obligations under this Agreement shall not terminate with respect to any claim, whether or not fixed as to liability or liquidated as to amount, with respect to which Fortress has been given an Indemnification Notice.

LU RESTRICTIVE COVENANT AGREEMENT
THIS LU RESTRICTIVE COVENANT AGREEMENT (as may be amended or modified from time to time, this “Agreement”) is made and entered into as of November 12, 2018, by and between InvaGen Pharmaceuticals Inc., a New York corporation (“Buyer”) and Lucy Lu, M.D. (“Dr. Lu”).
WHEREAS, Avenue Therapeutics, Inc., a Delaware corporation (the “Company”), Madison Pharmaceuticals, Inc., and Buyer have entered into that certain Stock Purchase and Merger Agreement, dated as of the date hereof  (the “SPMA”); and
WHEREAS, Dr. Lu is receiving a substantial economic benefit from the transactions contemplated by the SPMA, and Buyer would not have entered into the SPMA without the execution and delivery by Dr. Lu of this Agreement.
NOW THEREFORE, in consideration of the mutual promises and covenants contained herein, and other good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, the parties agree as follows:
1. Definitions.   Capitalized terms used but not defined in this Agreement shall have the respective meanings ascribed to them in the SPMA.
2. Restrictive Covenants.
(a) For a period commencing on the date hereof and ending on the earlier of  (i) (x) the termination of the SPMA in accordance with its terms if at the time of such termination the First Stage Closing has not occurred or (y) the date that is five years after the termination of the SPMA in accordance with its terms if at the time of such termination the First Stage Closing has occurred and (ii) five years after the Second Stage Closing Date (such period, the “Term”), Dr. Lu shall not (and shall cause her Affiliates not to), on her own or through any other Person, engage or participate in, or render services to (whether as owner, operator, member, stockholder, manager, consultant, strategic partner, employee or otherwise) any Person engaged in, the business of hospital administered pain management anywhere in the world other than Canada, Central America or South America (a “Competing Business”), including licensing, acquiring or seeking to develop Intellectual Property relating in any manner to hospital administered pain management, including by means of a collaboration agreement, partnership, joint venture, or other investment, or through sponsorship, management, research or development arrangements. During the Term, Dr. Lu shall not (and Dr. Lu shall cause her Affiliates not to), directly or indirectly, use or transfer to another Person, or facilitate the use or transfer by or to another Person, of any Investigational New Drug, NDA, “regulatory documents”, “essential documents” or any amendments thereto, any data or information contained in the files submitted to the FDA, or any other information or data, in each case, related to the Product or improvements thereon.
(b) During the Term, Dr. Lu shall not (and shall cause her Affiliates not to), directly or indirectly, (i) solicit for employment, recruit or hire, either as an employee or a consultant, any employee, consultant or independent contractor of the Company or Buyer or any of their respective Affiliates who was an employee, consultant or independent contractor of the Company or Buyer or any of their respective Affiliates as of the date of this Agreement or at any time thereafter and prior to the expiration of the Term to become an employee or consultant of, or otherwise provide services to, Dr. Lu, her Affiliates, or any entity to which she or any of them provide services, except, solely from and after the earlier of the Second Stage Closing and the termination of the SPMA, where such action with regard to any person set forth on Schedule 1 would not constitute a breach of Section 2(a) above, (ii) interfere or attempt to interfere with any transaction, agreement, prospective agreement, business opportunity or business relationship relating to the Product in which the Company or Buyer or any of their respective Affiliates is involved in as of the date of this Agreement or at any time thereafter and prior to the expiration of the Term or (iii) otherwise engage or participate in any effort or act to induce any Person to discontinue a relationship with the Company or Buyer or any of their respective Affiliates.

The obligations of Dr. Lu under this Section 2(c) shall not apply to information that (i) is obtained from public information, (ii) is received from a third party after the date hereof not, to the actual knowledge of Dr. Lu after reasonable investigation, subject to any obligation of confidentiality with respect to such information, or (iii) is or becomes known to the public, other than through a breach of this Agreement.

(a) Dr. Lu has read and understands the terms of this Agreement and agrees to be bound by its terms and conditions.
(b) Dr. Lu has the requisite legal capacity to enter into and perform this Agreement.
(c) This Agreement has been duly executed and delivered by Dr. Lu, and this Agreement constitutes the valid and binding agreement of Dr. Lu enforceable against her in accordance with its terms.
(d) The execution or delivery by Dr. Lu of this Agreement or the performance by Dr. Lu of her obligations under this Agreement will not (i) result in any breach of, require (with or without notice or lapse of time or both) any payment, consent or notice or constitute a default (or give rise to any right of purchase, termination, amendment, acceleration or cancellation) under any Contract or order or judgment to which Dr. Lu is a party or by which she or her assets are bound, (ii) result in the creation of an Encumbrance, or (iii) violate any applicable Legal Requirement, other than, in each case, such breaches, defaults or violations that have not had, or are not reasonably likely to have, a material adverse effect on the ability of Dr. Lu to perform her obligations under or to consummate the transactions contemplated by this Agreement.
4. Remedies.   Buyer and Dr. Lu acknowledge and agree that the remedies at law for any breach by Dr. Lu of any of the covenants or provisions of this Agreement are inadequate, and that Buyer shall be entitled to an injunction, specific performance or other equitable relief against Dr. Lu in the event of any breach. Dr. Lu agrees to reimburse Buyer any and all fees, costs and expenses (including reasonable attorneys’ fees) incurred for purposes of enforcing this Agreement in the event such enforcement is either consented to by Dr. Lu or ordered by a court of competent jurisdiction. Without limiting the foregoing, in the event of a breach or threatened breach by Dr. Lu of the terms of this Agreement, Buyer shall be entitled, if it so elects, to: (a) have the provisions of this Agreement specifically enforced by any court having equity jurisdiction or to enjoin Dr. Lu from any further violation of this Agreement; (b) require Dr. Lu to account for and pay over to Buyer all compensation, profits, monies, accruals, increments or other benefits derived or received by Dr. Lu as the result of any transactions constituting a breach of this Agreement, and Dr. Lu hereby agrees to promptly account for and pay over such benefits to Buyer; and (c) institute legal proceedings to obtain other monetary damages for any such breach. Without limiting the foregoing, Buyer shall be entitled to set-off any amount owed by Dr. Lu under this Agreement as a result of her breach hereof against any amount owed to Dr. Lu or any of its Affiliates under the SPMA or any Ancillary Agreement. Each of the rights and remedies enumerated above shall be independent of the others, and shall be severally enforceable, and all of such rights and remedies shall be in addition to, and not in lieu of, any other rights and remedies available to Buyer at law or in equity.
5. Severability.   In the event that any of the covenants or provisions of Section 2 hereof may be determined to be invalid, illegal or unenforceable by a court of competent jurisdiction in a final non-appealable judgment or order as a result of any time or scope (geographic or otherwise) limitations provided therein, Buyer and Dr. Lu expressly agree that such covenants and provisions shall be effective nevertheless for the greatest period of time and within the greatest scope (geographic or otherwise) that would not render them invalid, illegal or unenforceable, and in such event Dr. Lu hereby consents that such provisions may be judicially modified accordingly in any proceeding brought to enforce the provisions of
A-142

TABLE OF CONTENTS
Section 2 hereof. Any other covenant or provision of this Agreement that may be determined to be invalid, illegal or unenforceable shall be ineffective only to the extent of such invalidity, illegality or unenforceability without invalidating or rendering unenforceable any remaining provisions of this Agreement.

7. Acknowledgments.   Dr. Lu hereby acknowledges and agrees that (a) this Agreement (including the time, scope (geographic or otherwise) or any other limitations provided in Section 2 hereof) is reasonable and necessary for the protection of the immediate interests of Buyer, and that any violation of this Agreement would cause substantial injury to Buyer and that Buyer would not have entered into the SPMA, this Agreement and the other Ancillary Agreements without receiving the additional consideration offered by Dr. Lu in binding herself to this Agreement; (b) the scope of this Agreement, in terms of duration, geographic area, activities restricted and otherwise, is reasonable; and (c) Dr. Lu has had a reasonable opportunity to have this Agreement reviewed by legal counsel.
8. Miscellaneous.
(a) Entire Agreement.   This Agreement constitutes the entire agreement between the parties hereto with respect to the subject matter of this Agreement and supersedes any and all prior agreements, negotiations, correspondence, undertakings, understandings and communications of the parties hereto with respect to the subject matter of this Agreement.
(b) Transaction Costs.   Except as otherwise provided herein, the parties to this Agreement will pay their own costs and expenses (including legal, accounting and other fees) relating to this Agreement.
(c) Modifications.   Any amendment or modification to this Agreement, including this undertaking itself, shall only be valid if effected by an instrument or instruments in writing and shall be effective against each of the parties hereto that has signed such instrument or instruments. The parties agree that they jointly negotiated and prepared this Agreement and that this Agreement will not be construed against any party on the grounds that such party prepared or drafted the same.
(d) Notices.   Notices will be deemed to have been received (a) upon receipt of a registered letter, (b) three Business Days following proper deposit with an internationally recognized express overnight delivery service, or (c) in the case of transmission by email, as of the date so transmitted (or if so transmitted after normal business hours at the place of the recipient, on the Business Day following such transmission):

Any Company successor or assignee permitted hereunder may thereafter assign any or all of its rights, interests and obligations hereunder in the same manner as the Company pursuant to this Section 6.6.

the extent of such unenforceability or invalidity, and the parties will negotiate in good faith to modify this Agreement so that the unenforceable or invalid provision is replaced by such valid and enforceable provision which the parties consider, in good faith, to match as closely as possible the invalid or unenforceable provision and to achieve the same or a similar economic effect and to give effect to the parties’ original intent. The remaining provisions of this Agreement will continue to be binding and in full force and effect.

Section 6.10 Specific Performance.   Each party acknowledges and agrees that the other party would be irreparably damaged if the provisions of this Agreement are not performed in accordance with their terms and that any breach of this Agreement and the non-consummation of the transactions contemplated hereby by either party could not be adequately compensated in all cases by monetary damages alone. Accordingly, in addition to any remedy to which such other party may be entitled under Section 6.11, provisional measures and injunctive relief necessary to protect the possibility of each party to seek specific performance from the other from the tribunal referred to in Section 6.11 can be sought from any court of competent jurisdiction. Each of the parties hereto (i) agrees that it shall not oppose the granting of any such relief and (ii) hereby irrevocably waives any requirement for the security or posting of any bond in connection with any such relief  (it is understood that clause (i) of this sentence is not intended to, and shall not, preclude any party hereto from litigating on the merits the substantive claim to which such remedy relates).

Each of the parties hereto agrees that mailing of process or other papers in connection with any such action or proceeding in the manner provided in Section 6.4 or in such other manner as may be permitted by applicable Legal Requirements, will be valid and sufficient service thereof.

Each of the parties hereto hereby irrevocably waives, and agrees not to assert, by way of motion, as a defense, counterclaim, or otherwise, in any action or proceeding with respect to this Agreement and the rights and obligations arising hereunder, or for recognition and enforcement of any judgment in respect of this Agreement and the rights and obligations arising hereunder: (a) any claim that it is not personally subject to the jurisdiction of the above named courts for any reason other than the failure to serve process in accordance with this Section 6.11; (b) any claim that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise); and (c) to the fullest extent permitted by the applicable Legal Requirements, any claim that (i) the suit, action or proceeding in such court is brought in an inconvenient forum, (ii) the venue of such suit, action or proceeding is improper, or (iii) this Agreement, or the subject matter hereof, may not be enforced in or by such courts.

II. MEETINGS OF STOCKHOLDERS
2.1 Place of Meetings
Meetings of stockholders shall be held at any place, within or outside the State of Delaware, designated by the board of directors. The board of directors may, in its sole discretion, determine that a meeting shall not be held at any place, but may instead be held solely by means of remote communication as authorized by Section 211 of the General Corporation Law of Delaware.
If authorized by the board of directors in its sole discretion, and subject to such guidelines and procedures as the board of directors may adopt, stockholders and proxyholders not physically present at a meeting of stockholders may, by means of remote communication, participate in a meeting of stockholders, be deemed present in person and vote at a meeting of stockholders whether such meeting is to be held at a designated place or solely by means of remote communication, provided that (i) the corporation shall implement reasonable measures to verify that each person deemed present and permitted to vote at the meeting by means of remote communication is a stockholder or proxyholder, (ii) the corporation shall implement reasonable measures to provide such stockholders and proxyholders a reasonable opportunity to participate in the meeting and to vote on matters submitted to the stockholders, including an opportunity to read or hear the proceedings of the meeting substantially concurrently with such proceedings, and (iii) if any stockholder or proxyholder votes or takes other action at the meeting by means of remote communication, a record of such vote or other action shall be maintained by the corporation.

TABLE OF CONTENTS
2.4 Notice of Stockholders’ Meetings
(a) Except to the extent otherwise required by law, all notices of meetings with stockholders shall be in writing and shall be sent or otherwise given in accordance with Section 2.5 of these bylaws not less than ten (10) nor more than sixty (60) days before the date of the meeting to each stockholder entitled to vote at such meeting. The notice shall specify the place, if any, date, and hour of the meeting, the means of remote communication, if any, by which stockholders and proxyholders may be deemed to be present in person and vote at such meeting, and, in the case of a special meeting, the purpose or purposes for which the meeting is called.
(b) Without limiting the manner by which notice otherwise may be given effectively to stockholders, any notice to stockholders given by the corporation shall also be effective if given by a form of electronic transmission consented to by the stockholder to whom the notice is given. Any such consent shall be revocable by the stockholder by written notice to the corporation. Any such consent shall be deemed revoked if  (i) the corporation is unable to deliver by electronic transmission two consecutive notices given by the corporation in accordance with such consent, and (ii) such inability becomes known to the secretary or an assistant secretary of the corporation or to the transfer agent, or other person responsible for the giving of notice; provided, however, that the inadvertent failure to recognize such revocation shall not invalidate any meeting or other action.
(c) Without limiting the manner by which notice otherwise may be given effectively to stockholders, any notice to stockholders given by the corporation shall be effective if given by a single written notice to stockholders who share an address if consented to by the stockholders at that address to whom such notice is given. Any such consent shall be revocable by the stockholder by written notice to the corporation. Any stockholder who fails to object in writing to the corporation, within sixty (60) days of having been given written notice by the corporation of its intention to send the single notice permitted under this subsection 2.4(c), shall be deemed to have consented to receiving such single written notice.
(d) Sections 2.4(b) and (c) shall not apply to any notice given to stockholders under Sections 164 (notice of sale of shares of stockholder who failed to pay an installment or call on stock not fully paid), 296 (notice of disputed claims relating to insolvent corporations), 311 (notice of meeting of stockholders to revoke dissolution of corporation), 312 (notice of meeting of stockholders of corporation whose certificate of incorporation has been renewed or revived) and 324 (notice when stock has been attached as required for sale upon execution process) of the General Corporation Law of Delaware.
2.5 Manner of Giving Notice; Affidavit of Notice
(a) Written notice of any meeting of stockholders, if mailed, is given when deposited in the United States mail, postage prepaid, directed to the stockholder at his, her or its address as it appears on the records of the corporation. An affidavit of the secretary or an assistant secretary or of the transfer agent or other agent of the corporation that the notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein.
(b) Notice given pursuant to this Section 2.5(b) shall be deemed given: (i) if by facsimile telecommunication, when directed to a number at which the stockholder has consented to receive notice; (ii) if by electronic mail, when directed to an electronic mail address at which the stockholder has consented to receive notice; (iii) if by a posting on an electronic network together with separate notice to the stockholder of such specific posting, upon the later of such posting and the giving of such separate notice; and (iv) if by any other form of electronic transmission, when directed to the stockholder. An affidavit of the secretary, an assistant secretary or the transfer agent or other agent of the corporation that the notice has been given by a form of electronic transmission shall, in the absence of fraud, be prima facie evidence of the facts stated therein.
2.6 Quorum
The holders of a majority of the stock issued and outstanding and entitled to vote thereat, present in person or represented by proxy, shall constitute a quorum at all meetings of the stockholders for the transaction of business except as otherwise provided by statute or by the certificate of incorporation. If,
A-175

TABLE OF CONTENTS
however, such quorum is not present or represented at any meeting of the stockholders, then the stockholders entitled to vote thereat, present in person or represented by proxy, shall have power to adjourn the meeting from time to time, without notice other than announcement at the meeting, until a quorum is present or represented. At such adjourned meeting at which a quorum is present or represented, any business may be transacted that might have been transacted at the meeting as originally noticed.
2.7 Adjourned Meeting; Notice
When a meeting is adjourned to another time or place, unless these bylaws otherwise require, notice need not be given of the adjourned meeting if the time and place thereof, and the means of remote communication, if any, by which stockholders and proxyholders may be deemed to be present in person and vote at such meeting, are announced at the meeting at which the adjournment is taken. At the adjourned meeting the corporation may transact any business that might have been transacted at the original meeting. If the adjournment is for more than thirty (30) days, or if after the adjournment a new record date is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting.
2.8 Voting
The stockholders entitled to vote at any meeting of stockholders shall be determined in accordance with the provisions of Section 2.11 of these bylaws, subject to the provisions of Sections 217 and 218 of the General Corporation Law of Delaware (relating to voting rights of fiduciaries, pledgors and joint owners of stock and to voting trusts and other voting agreements).
Except as otherwise provided in the certificate of incorporation, each stockholder shall be entitled to one vote for each share of capital stock held by such stockholder.
2.9 Waiver of Notice
Whenever notice is required to be given under any provision of the General Corporation Law of Delaware or of the certificate of incorporation or these bylaws, a written waiver thereof, signed by the person entitled to notice, or a waiver by electronic transmission by the person entitled to notice, whether before or after the time stated therein, shall be deemed equivalent to notice. Attendance of a person at a meeting shall constitute a waiver of notice of such meeting, except when the person attends a meeting for the express purpose of objecting, at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened. Neither the business to be transacted at, nor the purpose of, any regular or special meeting of the stockholders need be specified in any written waiver or any waiver by electronic transmission of notice unless so required by the certificate of incorporation or these bylaws.
2.10 Stockholder Action by Written Consent Without a Meeting
Unless otherwise provided in the certificate of incorporation, any action required by the General Corporation Law of Delaware to be taken at any annual or special meeting of stockholders of a corporation, or any action that may be taken at any annual or special meeting of such stockholders, may be taken without a meeting, without prior notice, and without a vote if a consent in writing, setting forth the action so taken, is signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted. A telegram, cablegram or other electronic transmission consenting to an action to be taken and transmitted by a stockholder, proxyholder or other person or persons authorized to act for a stockholder or proxyholder, shall be deemed to be written, signed and dated for the purposes of this Section 2.10, provided that any such telegram, cablegram or other electronic transmission sets forth or is delivered with information from which the corporation can determine (a) that the telegram, cablegram or other electronic transmission was transmitted by the stockholder, proxyholder or other authorized person or persons, and (b) the date on which such stockholder, proxyholder or other authorized person or persons transmitted such telegram, cablegram or electronic transmission. The date on which such telegram, cablegram or electronic transmission is transmitted shall be deemed to be the date on which such consent was signed. No consent given by telegram, cablegram or other electronic transmission shall be deemed to
A-176

TABLE OF CONTENTS
have been delivered until such consent is reproduced in paper form and until such paper form shall have been delivered to the corporation by delivery to its registered office in this State, its principal place of business or an officer or agent of the corporation having custody of the book in which proceedings of meetings of stockholders are recorded. Delivery made to the corporation’s registered office shall be made by hand or by certified or registered mail, return receipt requested. Notwithstanding the foregoing limitations on delivery, consents given by telegram, cablegram or other electronic transmission may be otherwise delivered to the principal place of business of the corporation or to an officer or agent of the corporation having custody of the book in which proceedings of meetings of stockholders are recorded, to the extent and in the manner provided by resolution of the board of directors of the corporation. Any copy, facsimile or other reliable reproduction of a consent in writing may be substituted or used in lieu of the original writing for any and all purposes for which the original writing could be used, provided that such copy, facsimile or other reproduction shall be a complete reproduction of the entire original writing.
Prompt notice of the taking of the corporate action without a meeting by written consent shall be given to those stockholders who have not consented in writing. If the action that is consented to is such as would have required the filing of a certificate under any section of the General Corporation Law of Delaware if such action had been voted on by stockholders at a meeting thereof, then the certificate filed under such section shall state, in lieu of any statement required by such section concerning any vote of stockholders, that written notice and written consent have been given as provided in Section 228 of the General Corporation Law of Delaware.
2.11 Record Date for Stockholder Notice; Voting; Giving Consents
In order that the corporation may determine the stockholders entitled to notice of or to vote at any meeting of stockholders or any adjournment thereof, or entitled to express consent to corporate action in writing without a meeting, or entitled to receive payment of any dividend or other distribution or allotment of any rights, or entitled to exercise any rights in respect of any change, conversion or exchange of stock or for the purpose of any other lawful action, the board of directors may fix, in advance, a record date that shall not be more than sixty (60) nor less than ten (10) days before the date of such meeting, nor more than sixty (60) days prior to any other action.
If the board of directors does not so fix a record date:
(a) the record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be at the close of business on the day next preceding the day on which notice is given, or, if notice is waived, at the close of business on the day next preceding the day on which the meeting is held;
(b) the record date for determining stockholders entitled to express consent to corporate action in writing without a meeting, when no prior action by the board of directors is necessary, shall be the day on which the first written consent is expressed; and
(c) the record date for determining stockholders for any other purpose shall be at the close of business on the day on which the board of directors adopts the resolution relating thereto.
A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting; provided, however, that the board of directors may fix a new record date for the adjourned meeting.
2.12 Proxies
Each stockholder entitled to vote at a meeting of stockholders or to express consent or dissent to corporate action in writing without a meeting may authorize another person or persons to act for him by a written proxy, signed by the stockholder and filed with the secretary of the corporation, but no such proxy shall be voted or acted upon after three (3) years from its date, unless the proxy provides for a longer period. A proxy shall be deemed signed if the stockholder’s name is placed on the proxy (whether by manual signature, typewriting, telegraphic transmission or otherwise) by the stockholder or the stockholder’s attorney-in-fact. The revocability of a proxy that states on its face that it is irrevocable shall be governed by the provisions of Section 212(e) of the General Corporation Law of Delaware.
A-177

TABLE OF CONTENTS
2.13 List of Stockholders Entitled to Vote
The officer who has charge of the stock ledger of a corporation shall prepare and make, at least ten (10) days before every meeting of stockholders, a complete list of the stockholders entitled to vote at the meeting, arranged in alphabetical order, and showing the address of each stockholder and the number of shares registered in the name of each stockholder. The corporation shall not be required to include electronic mail addresses or other electronic contact information on such list. Such list shall be open to the examination of any stockholder for any purpose germane to the meeting for a period of at least ten (10) days prior to the meeting: (a) on a reasonably accessible electronic network, provided that the information required to gain access to such list is provided with the notice of the meeting, or (b) during ordinary business hours, at the principal place of business of the corporation. In the event that the corporation determines to make the list available on an electronic network, the corporation may take reasonable steps to ensure that such information is available only to stockholders of the corporation. If the meeting is to be held at a place, then the list shall be produced and kept at the time and place of the meeting during the whole time thereof, and may be examined by any stockholder who is present. If the meeting is to be held solely by means of remote communication, then the list shall also be open to the examination of any stockholder during the whole time of the meeting on a reasonably accessible electronic network, and the information required to access such list shall be provided with the notice of the meeting.
2.14 Stockholder Proposals
Effective upon the corporation’s initial public offering of stock under the Securities Act of 1933, as amended, any stockholder wishing to bring any other business before a meeting of stockholders, including, but not limited to, the nomination of persons for election as directors, must provide notice to the corporation not more than ninety (90) and not less than fifty (50) days before the meeting in writing by registered mail, return receipt requested, of the business to be presented by the stockholders at the stockholders’ meeting. Any such notice shall set forth the following as to each matter the stockholder proposes to bring before the meeting: (a) a brief description of the business desired to be brought before the meeting and the reasons for conducting such business at the meeting and, if such business includes a proposal to amend the bylaws of the corporation, the language of the proposed amendment; (b) the name and address, as they appear on the corporation’s books, of the stockholder proposing such business; (c) the class and number of shares of the corporation that are beneficially owned by such stockholder; (d) a representation that the stockholder is a holder of record of stock of the corporation entitled to vote at such meeting and intends to appear in person or by proxy at the meeting to propose such business; and (e) any material interest of the stockholder in such business. Notwithstanding the foregoing provisions of this Section 2.14, a stockholder shall also comply with all applicable requirements of all applicable laws, rules and regulations, including, but not limited to, the Securities Act of 1933, as amended, and the rules and regulations promulgated thereunder, with respect to the matters set forth in this Section 2.14. In the absence of such notice to the corporation meeting the above requirements, a stockholder shall not be entitled to present any business at any meeting of stockholders.
III. DIRECTORS
3.1 Powers
Subject to the provisions of the General Corporation Law of Delaware and any limitations in the certificate of incorporation or these bylaws relating to action required to be approved by the stockholders or by the outstanding shares, the business and affairs of the corporation shall be managed and all corporate powers shall be exercised by or under the direction of the board of directors.
3.2 Number of Directors
The number of directors constituting the board of directors shall be not more than seven (7) but not less than one (1), and may be fixed or changed, within this minimum and maximum, by the stockholders or the board of directors.

(“InvaGen”) has the right to nominate the InvaGen Directors (as defined in Section 3.3 herein), the size of the board of directors may only be increased or decreased upon consent of an authorized officer of InvaGen (as confirmed in accordance with Section 12.4 of the SPMA).
A-178

TABLE OF CONTENTS
No reduction of the authorized number of directors shall have the effect of removing any director before that director’s term of office expires.
3.3 Election, Qualification and Term of Office of Directors
Except as provided in this Section 3.3 and in Section 3.4 of these bylaws, directors shall be elected at each annual meeting of stockholders to hold office until the next annual meeting. Directors need not be stockholders unless so required by the certificate of incorporation or these bylaws, wherein other qualifications for directors may be prescribed. Each director, including a director elected to fill a vacancy, shall hold office until his or her successor is elected and qualified or until his or her earlier resignation or removal. Each director shall be a natural person.
Elections of directors need not be by written ballot.
At any time that InvaGen beneficially owns at least 75% of the First Stage Shares (as defined in the SPMA), InvaGen shall have the right to nominate three members to the board of directors (each, an “InvaGen Director”), initially upon the closing of the Stock Purchase Transaction pursuant to that certain Stock Purchase and Merger Agreement by and among InvaGen, Madison Pharmaceuticals Inc. and the corporation dated November 12, 2018 (the “SPMA”), and thereafter at every annual meeting of the stockholders of the corporation in which directors are generally elected, including at every adjournment or postponement thereof, and on any action by written consent of the stockholders of the corporation relating to the election of directors generally. At least one of the InvaGen Directors shall be “Independent” as determined by the board of directors pursuant to Rule 5605 of The Nasdaq Stock Market (“Nasdaq”) and the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”).
(a) The following procedures shall be followed with respect to the nomination of InvaGen Directors for election at annual meetings of stockholders of the corporation pursuant to this Section 3.3:
(i) For purposes of determining whether InvaGen has a right to nominate an InvaGen Director pursuant to this Section 3.3 and for purposes of Article IX herein, the beneficial ownership of the common stock of the corporation shall be measured as of the record date for such annual meeting or written consent. If any change in the outstanding shares of capital stock of the corporation shall occur, including by reason of any issuance (including upon exercise of warrants), reclassification, recapitalization, stock split (including a reverse stock split), or combination, exchange, readjustment of shares, consolidation, split, buy-back, repurchase, redemption, acquisition or similar transaction, or any stock dividend or distribution paid in stock, the calculation of beneficial ownership under this Section 3.3 and under Article IX herein shall be equitably adjusted to proportionately reflect such change.
(ii) Each year, the corporation will notify InvaGen when it intends to hold its next corporation’s annual meeting of stockholders at least 120 days prior to such meeting. With respect to InvaGen’s nominees, at least 90 days prior to the corporation’s annual meeting of stockholders, InvaGen shall provide the corporation with the InvaGen’s nominees for the InvaGen Directors, along with any other information reasonably requested by the independent directors of the corporation pursuant to Rule 5605 of Nasdaq and the rules and regulations of the SEC (the “Independent Directors”) to evaluate the suitability of such candidates for directorship.

If the Independent Directors do not notify InvaGen of their determination within the 10 day period specified above, then InvaGen’s nominees shall be deemed to be approved for purposes of Section 3.3(a)(iv) below. If InvaGen and the Independent Directors do not agree on the nominee(s) within 30 days after the Independent Directors raise an objection to an InvaGen Director nomination, the InvaGen Director(s) shall not be nominated by the corporation at such annual meeting. The Independent Directors may not disqualify a nominee

(v) If any InvaGen nominee(s) is not appointed, nominated or elected by the stockholders, then as soon as practicable after the annual meeting, as applicable, InvaGen shall designate nominee(s) for such InvaGen Director(s) (subject to the limitations on the Independent Directors’ ability to raise an objection as specified in clause (iii) of this Section 3.3(a)), which nominee(s) shall be appointed as director(s) by the board of directors promptly after such designation.
(vi) In the event an InvaGen Director resigns from the board of directors (or is otherwise incapable of serving on the board of directors), the remaining InvaGen Directors shall have the power to fill such vacancy. So long as the InvaGen Director replacement satisfies the criteria in Sections 3.3(a)(ii)-(iii), the board of directors shall vote in favor of such InvaGen Director replacement.

VI. INDEMNITY
6.1 Indemnification of Directors and Officers
The corporation shall, to the maximum extent and in the manner permitted by the General Corporation Law of Delaware, indemnify each of its directors and Officers against expenses (including attorneys’ fees), judgments, fines, settlements, and other amounts actually and reasonably incurred in connection with any proceeding, arising by reason of the fact that such person is or was an agent of the corporation. For purposes of this Section 6.1, a director or Officer of the corporation includes any person (a) who is or was a director or Officer of the corporation, (b) who is or was serving at the request of the corporation as a director, Officer manager, member, partner, trustee, or other agent of another corporation, limited liability company, partnership, joint venture, trust or other enterprise, or (c) who was a director or Officer of a corporation that was a predecessor corporation of the corporation or of another enterprise at the request of such predecessor corporation. Such indemnification shall be a contract right and shall include the right to receive payment of any expenses incurred by the indemnitee in connection with any proceeding in advance of its final disposition, consistent with the provisions of applicable law as then in effect. The right of indemnification provided in this Section 6.1 shall not be exclusive of any other rights to which those seeking indemnification may otherwise be entitled, and the provisions of this Section 6.1 shall inure to the benefit of the heirs and legal representatives of any person entitled to indemnity under this Section 6.1 and shall be applicable to proceedings commenced or continuing after the adoption of this Section 6.1, whether arising from acts or omissions occurring before or after such adoption. In furtherance, but not in limitation of the foregoing provisions, the following procedures, presumptions and remedies shall apply with respect to advancement of expenses and the right to indemnification under this Section 6.1.
(a) Advancement of Expenses.   All reasonable expenses incurred by or on behalf of the indemnitee in connection with any proceeding shall be advanced to the indemnitee by the corporation within twenty (20) days after the receipt by the corporation of a statement or statements from the indemnitee requesting such advance or advances from time to time, whether prior to or after final disposition of such proceeding, unless, prior to the expiration of such twenty-day period, the board of directors shall unanimously (except for the vote, if applicable, of the indemnitee) determine that the indemnitee has no reasonable likelihood of being entitled to indemnification pursuant to this Section 6.1. Such statement or statements shall reasonably evidence the expenses incurred by the indemnitee and, if required by law at the time of such advance, shall include or be accompanied by an undertaking by or on behalf of the indemnitee to repay the amounts advanced if it should ultimately be determined that the indemnitee is not entitled to be indemnified against such expenses pursuant to this Section 6.1.
(b) Procedure for Determination of Entitlement to Indemnification.
(i) To obtain indemnification under this Section 6.1, an indemnitee shall submit to the secretary of the corporation a written request, including such documentation and information as is reasonably available to the indemnitee and reasonably necessary to determine whether and to what extent the indemnitee is entitled to indemnification (the “Supporting Documentation”). The determination of the indemnitee’s entitlement to indemnification shall be made not later than sixty (60) days after receipt by the corporation of the written request for indemnification together with the Supporting Documentation. The secretary of the corporation shall, promptly upon
A-186

TABLE OF CONTENTS
receipt of such a request for indemnification, advise the board of directors in writing that the indemnitee has requested indemnification, whereupon the corporation shall provide such indemnification, including without limitation advancement of expenses, so long as the indemnitee is legally entitled thereto in accordance with applicable law.
(ii) The indemnitee’s entitlement to indemnification under this Section 6.1 shall be determined in one of the following ways: (A) by a majority vote of the Disinterested Directors (as hereinafter defined), even though less than a quorum of the board of directors; (B) by a committee of such Disinterested Directors, even though less than a quorum of the board of directors; (C) by a written opinion of Independent Counsel (as hereinafter defined) if  (x) a Change of Control (as hereinafter defined) shall have occurred and the indemnitee so requests or (y) a quorum of the board of directors consisting of Disinterested Directors is not obtainable or, even if obtainable, a majority of such Disinterested Directors so directs; (D) by the stockholders of the corporation (but only if a majority of the Disinterested Directors, if they constitute a quorum of the board of directors, presents the issue of entitlement to indemnification to the stockholders for their determination); or (E) as provided in paragraph (c) below.
(iii) In the event the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to paragraph (b)(ii) above, a majority of the Disinterested Directors shall select the Independent Counsel, but only an Independent Counsel to which the indemnitee does not reasonably object; provided, however, that if a Change of Control shall have occurred, the indemnitee shall select such Independent Counsel, but only an Independent Counsel to which the board of directors does not reasonably object.
(iv) The only basis upon which a finding that indemnification may not be made is that such indemnification is prohibited by law.
(c) Presumptions and Effect of Certain Proceedings.   Except as otherwise expressly provided in this Section 6.1, if a Change of Control shall have occurred, the indemnitee shall be presumed to be entitled to indemnification under this Section 6.1 upon submission of a request for Indemnification together with the Supporting Documentation in accordance with paragraph (b)(i), and thereafter the corporation shall have the burden of proof to overcome that presumption in reaching a contrary determination. In any event, if the person or persons empowered under paragraph (b)(ii) above to determine entitlement to indemnification shall not have been appointed or shall not have made a determination within sixty (60) days after receipt by the corporation of the request therefor together with the Supporting Documentation, the indemnitee shall be deemed to be entitled to indemnification and the indemnitee shall be entitled to such indemnification unless (A) the indemnitee misrepresented or failed to disclose a material fact in making the request for indemnification or in the Supporting Documentation or (B) such indemnification is prohibited by law. The termination of any proceeding described in this Section 6.1, or of any claim, issue or matter therein, by judgment, order, settlement or conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, adversely affect the right of the indemnitee to indemnification or create a presumption that the indemnitee did not act in good faith and in a manner that the indemnitee reasonably believed to be in or not opposed to the best interests of the corporation or, with respect to any criminal proceeding, that the indemnitee had reasonable cause to believe that the indemnitee’s conduct was unlawful.
(d) Remedies of Indemnitee.
(i) In the event that a determination is made pursuant to paragraph (b)(ii) that the indemnitee is not entitled to indemnification under this Section 6.1: (A) the indemnitee shall be entitled to seek an adjudication of his or her entitlement to such indemnification either, at the indemnitee’s sole option, in (x) an appropriate court of the State of Delaware or any other court of competent jurisdiction, or (y) an arbitration to be conducted by a single arbitrator pursuant to the rules of the American Arbitration Association; (B) any such judicial proceeding or arbitration shall be de novo and the indemnitee shall not be prejudiced by reason of such adverse determination; and (C) in any such judicial proceeding or arbitration the corporation shall have the burden of proving that the indemnitee is not entitled to indemnification under this Section 6.1.
A-187

TABLE OF CONTENTS
(ii) If a determination shall have been made or is deemed to have been made, pursuant to paragraph (b)(ii) or (iii), that the indemnitee is entitled to indemnification, the corporation shall be obligated to pay the amounts constituting such indemnification within five (5) days after such determination has been made or is deemed to have been made and shall be conclusively bound by such determination unless (A) the indemnitee misrepresented or failed to disclose a material fact in making the request for indemnification or in the Supporting Documentation, or (B) such indemnification is prohibited by law. In the event that: (X) advancement of expenses is not timely made pursuant to paragraph (a); or (Y) payment of indemnification is not made within five (5) days after a determination of entitlement to indemnification has been made or deemed to have been made pursuant to paragraph (b)(ii) or (iii), the indemnitee shall be entitled to seek judicial enforcement of the corporation’s obligation to pay to the indemnitee such advancement of expenses or indemnification. Notwithstanding the foregoing, the corporation may bring an action, in an appropriate court in the State of Delaware or any other court of competent jurisdiction, contesting the right of the indemnitee to receive indemnification hereunder due to the occurrence of an event described in subclause (A) or (B) of this clause (ii) (a “Disqualifying Event”); provided, however, that in any such action the corporation shall have the burden of proving the occurrence of such Disqualifying Event.
(iii) The corporation shall be precluded from asserting in any judicial proceedings or arbitration commenced pursuant to this paragraph (d) that the procedures and presumptions of this Section 6.1 are not valid, binding and enforceable and shall stipulate in any such court or before any such arbitrator that the corporation is bound by all the provisions of this Section 6.1.
(iv) In the event that the indemnitee, pursuant to this paragraph (d), seeks a judicial adjudication of or an award in arbitration to enforce his or her rights under, or to recover damages for breach of, this Section 6.1, the indemnitee shall be entitled to recover from the corporation, and shall be indemnified by the corporation against, any expenses actually and reasonably incurred by the indemnitee if the indemnitee prevails in such judicial adjudication or arbitration.

TABLE OF CONTENTS
seeks the right to inspection, the demand under oath shall be accompanied by a power of attorney or such other writing that authorizes the attorney or other agent to so act on behalf of the stockholder. The demand under oath shall be directed to the corporation at its registered office in Delaware or at its principal place of business.
Any records maintained by a corporation in the regular course of its business, including its stock ledger, books of account and minute books, may be kept on, or by means of, or be in the form of, any information storage device or method, provided that the records so kept can be converted into clearly legible paper form within a reasonable time. Any corporation shall so convert any records so kept upon the request of any person entitled to inspect such records pursuant to any provision of the certificate of incorporation, these bylaws or the General Corporation Law of Delaware. When records are kept in such manner, a clearly legible paper from or by means of the information storage device or method shall be admissible in evidence, and accepted for all other purposes, to the same extent as an original paper record of the same information would have been, provided the paper form accurately portrays the record.

The court may summarily order the corporation to permit the director to inspect any and all books and records, the stock ledger and the stock list and to make copies or extracts therefrom. The burden of proof shall be upon the corporation to establish that the inspection such director seeks is for an improper purpose. The court may, in its discretion, prescribe any limitations or conditions with reference to the inspection, or award such other and further relief as the court may deem just and proper.

If the corporation is authorized to issue more than one class of stock or more than one series of any class, then the powers, the designations, the preferences, and the relative, participating, optional or other special rights of each class of stock or series thereof and the qualifications, limitations or restrictions of such preferences and/or rights shall be set forth in full or summarized on the face or back of the certificate that the corporation shall issue to represent such class or series of stock; provided, however, that, except as otherwise provided in Section 202 of the General Corporation Law of Delaware, in lieu of the foregoing requirements there may be set forth on the face or back of the certificate that the corporation shall issue to represent such class or series of stock a statement that the corporation will furnish without charge to each stockholder who so requests the powers, the designations, the preferences, and the relative, participating, optional or other special rights of each class of stock or series thereof and the qualifications, limitations or restrictions of such preferences and/or rights.
8.5 Lost Certificates
Except as provided in this Section 8.5, no new certificates for shares shall be issued to replace a previously issued certificate unless the latter is surrendered to the corporation and cancelled at the same time. The corporation may issue a new certificate of stock or uncertificated shares in the place of any certificate theretofore issued by it, alleged to have been lost, stolen or destroyed, and the corporation may require the owner of the lost, stolen or destroyed certificate, or his or her legal representative, to give the corporation a bond sufficient to indemnify it against any claim that may be made against it on account of the alleged loss, theft or destruction of any such certificate or the issuance of such new certificate or uncertificated shares.

Upon surrender to the corporation or the transfer agent of the corporation of a certificate for shares duly endorsed or accompanied by proper evidence of succession, assignation or authority to transfer, it shall be the duty of the corporation to issue a new certificate to the person entitled thereto, cancel the old certificate and record the transaction in its books.
8.11 Stock Transfer Agreements and Restrictions
The corporation shall have power to enter into and perform any agreement with any number of stockholders of any one or more classes of stock of the corporation to restrict the transfer of shares of stock of the corporation of any one or more classes owned by such stockholders in any manner not prohibited by the General Corporation Law of Delaware.
8.12 Electronic Transmission

IX. AMENDMENTS
The original or other bylaws of the corporation may be adopted, amended or repealed by the stockholders entitled to vote; provided, however, that the corporation may, in its certificate of incorporation, confer the power to adopt, amend or repeal bylaws upon the directors; provided, further, that these bylaws shall not be amended or repealed without the prior consent of an authorized officer of InvaGen (as confirmed in accordance with Section 12.4 of the SPMA), (a) if the SPMA has not been terminated, until the Second Stage Closing (as defined therein), and (b) if the SPMA has been terminated, at any time that InvaGen beneficially owns at least 75% of the First Stage Shares. The fact that such power has been so conferred upon the directors shall not divest the stockholders of the power, nor limit their power to adopt, amend or repeal bylaws.
X. DISSOLUTION
If it should be deemed advisable in the judgment of the board of directors of the corporation that the corporation should be dissolved, the board, after the adoption of a resolution to that effect by a majority of the whole board at any meeting called for that purpose, shall cause notice to be mailed to each stockholder entitled to vote thereon of the adoption of the resolution and of a meeting of stockholders to take action upon the resolution.
At the meeting a vote shall be taken for and against the proposed dissolution. If a majority of the outstanding stock of the corporation entitled to vote thereon votes for the proposed dissolution, then a certificate stating, among other things, that the dissolution has been authorized in accordance with the provisions of Section 275 of the General Corporation Law of Delaware and setting forth the names and
A-192

TABLE OF CONTENTS
residences of the directors and officers shall be executed, acknowledged, and filed and shall become effective in accordance with Section 103 of the General Corporation Law of Delaware.

Whenever all the stockholders entitled to vote on a dissolution consent in writing, either in person or by duly authorized attorney, to a dissolution, no meeting of directors or stockholders shall be necessary. The consent shall be filed and shall become effective in accordance with Section 103 of the General Corporation Law of Delaware. Upon such consent’s becoming effective in accordance with Section 103 of the General Corporation Law of Delaware, the corporation shall be dissolved. If the consent is signed by an attorney, then the original power of attorney or a photocopy thereof shall be attached to and filed with the consent. The consent filed with the Secretary of State shall have attached to it the affidavit of the secretary or some other officer of the corporation stating that the consent has been signed by or on behalf of all the stockholders entitled to vote on a dissolution; in addition, there shall be attached to the consent a certification by the secretary or some other officer of the corporation setting forth the names and residences of the directors and officers of the corporation.
XI. CUSTODIAN
11.1 Appointment of a Custodian in Certain Cases
The Court of Chancery, upon application of any stockholder, may appoint one or more persons to be custodians and, if the corporation is insolvent, to be receivers, of and for the corporation when:
(a) at any meeting held for the election of directors the stockholders are so divided that they have failed to elect successors to directors whose terms have expired or would have expired upon qualification of their successors;
(b) the business of the corporation is suffering or is threatened with irreparable injury because the directors are so divided respecting the management of the affairs of the corporation that the required vote for action by the board of directors cannot be obtained and the stockholders are unable to terminate this division; or
(c) the corporation has abandoned its business and has failed within a reasonable time to take steps to dissolve, liquidate or distribute its assets.
11.2 Duties of Custodian
The custodian shall have all the powers and title of a receiver appointed under Section 291 of the General Corporation Law of Delaware, but the authority of the custodian shall be to continue the business of the corporation and not to liquidate its affairs and distribute its assets, except when the Court of Chancery otherwise orders and except in cases arising under Sections 226(a)(3) or 352(a)(2) of the General Corporation Law of Delaware.

Section 2.14 Indemnification.   The Corporation shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending, or contemplated action, suit, or proceeding, whether civil, criminal, administrative, or investigative (other than an action by or in the right of the Corporation), by reason of the fact that he or she is or was a director or officer of the Corporation, or is or was serving at the request of the Corporation as a director, officer, trustee, employee, or agent of another corporation, partnership, joint venture, trust, or other enterprise (all of such persons being hereafter referred to in this Article as a “Corporate Fiduciary”), against expenses (including attorneys’ fees), judgments, fines, and amounts paid in settlement actually and reasonably incurred by him or her in connection with such action, suit, or proceeding, if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the Corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. The termination of any action, suit, or proceeding by judgment, order, settlement, or conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which he or she reasonably believed to be in or not opposed to the best interests of the Corporation or, with respect to any criminal action or proceeding, that he or she had reasonable cause to believe that his or her conduct was unlawful.
The Corporation shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending, or contemplated action of suit by or in the right of the Corporation to procure a judgment in its favor by reason of the fact that he or she is or was a Corporate Fiduciary against expenses (including attorneys’ fees) actually and reasonably incurred by him or her in connection with the defense or settlement of such action or suit, if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the Corporation, except that no indemnification shall be made in respect of any claim, issue, or matter as to which such person shall have been adjudged to be liable to the Corporation, unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.
Notwithstanding the other provisions of this Section 2.14, to the extent that a Corporate Fiduciary has been successful on the merits or otherwise in defense of any action, suit, or proceeding referred to in the first two paragraphs of this Section 2.14 (including the dismissal of a proceeding without prejudice or the settlement of a proceeding without admission of liability), or in defense of any claim, issue, or matter therein, he or she shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by him or her in connection therewith.
Expenses incurred in defending a civil or criminal action, suit, or proceeding shall be paid by the Corporation in advance of the final disposition of such action, suit, or proceeding, upon receipt of an undertaking by or on behalf of the Corporate Fiduciary to repay such amount if it shall ultimately be determined he or she is not entitled to be indemnified by the Corporation as authorized in this Section 2.14.
Any indemnification under the first, second or third paragraphs of this Section 2.14, or any advance under the fourth paragraph of this Section 2.14, shall be made promptly upon, and in any event within 60 days after, the written request of the Corporate Fiduciary, unless, with respect to applications under the first, second, or fourth paragraphs of this Section 2.14, a determination that such Corporate Fiduciary acted in a manner set forth in such paragraphs as to justify the Corporation in not indemnifying or making an advance of expenses to the Corporate Fiduciary is reasonably and promptly made (i) by the Board of Directors by a majority vote of a quorum consisting of disinterested directors, or (ii) if such a quorum is not obtainable, or, even if obtainable, if a quorum of disinterested directors so directs, by independent legal counsel in a written opinion, or (iii) by the stockholders. The right to indemnification or advance of expenses granted by this Section 2.14 shall be enforceable by the Corporate Fiduciary in any court of competent jurisdiction if the Board of Directors or independent legal counsel denies his or her claim, in whole or in part, or if no disposition of such claim is made within 60 days. The expenses of the Corporate Fiduciary incurred in connection with successfully establishing his or her right to indemnification, in whole or in part, in any such proceeding shall also be indemnified by the Corporation.
The indemnification and advancement of expenses provided by or granted pursuant to this Section 2.14 shall not be deemed exclusive of any other rights to which any person seeking indemnification
A-204

TABLE OF CONTENTS
and advancement of expenses may be entitled under any bylaw, agreement, vote of stockholders or disinterested directors, or otherwise, both as to action in his or her official capacity and as to action in another capacity while holding such office, and shall, unless otherwise provided when authorized or ratified, continue as to a person who has ceased to be a Corporate Fiduciary and shall inure to the benefit of the heirs, executors, and administrators of such a person. Any repeal or modification of these Bylaws or relevant provisions of the Delaware General Corporation Law and other applicable law, if any, shall not affect any then existing rights of a Corporate Fiduciary to indemnification or advancement of expenses.
Upon resolution passed by the Board of Directors, the Corporation may purchase and maintain insurance on behalf of any person who is or was a director, officer, employee, or agent of the Corporation, or is or was serving at the request of the Corporation as a director, officer, employee, or agent of another corporation, partnership, joint venture, trust, or other enterprise against any liability asserted against him or her and incurred by him or her in any such capacity, or arising out of his or her status as such, whether or not the Corporation would have the power to indemnify him or her against such liability under the provisions of this Section 2.14.

To the extent the Company is a WKSI at the time that the Shelf Registration Statement is to be filed, the Company shall file an automatic Shelf Registration Statement which covers such Registrable Securities. The Company agrees to use commercially reasonable efforts to keep the Shelf Registration Statement (or a successor Registration Statement filed with respect to the Registrable Securities) continuously effective (including by filing a new Shelf Registration Statement if the initial Shelf Registration Statement expires) in order to permit the Prospectus forming a part thereof to be lawfully delivered and the Shelf Registration Statement useable for resale of the Registrable Securities, so long as there are any Registrable Securities outstanding (the “Shelf Effectiveness Period”).

Upon receipt of the Non-Shelf Demand Registration Notice, the Company will use commercially reasonable efforts to file with the SEC as promptly as practicable after receiving the Non-Shelf Demand Registration Notice, but in no event more than 45 days following receipt of such notice, a Registration Statement covering all requested Registrable Securities (the “Non-Shelf Demand Registration Statement”), and agrees to use commercially reasonable efforts to cause the Non-Shelf Demand Registration Statement to be declared effective by the SEC as soon as reasonably practicable following the filing thereof.

(g) promptly notify the Buyer: (i) when the Registration Statement, any pre-effective amendment, the Prospectus or any prospectus supplement related thereto or post-effective amendment to the Registration Statement has been filed, and, with respect to the Registration Statement or any post-effective amendment, when the same has become effective, (ii) of the issuance by the SEC of any stop order suspending the effectiveness of the Registration Statement or the initiation or threat of any

(a) against any and all loss, liability, claim, damage, action, cost, judgment and expense whatsoever (including reasonable fees, expenses and disbursements of attorneys and other professionals), as incurred, arising out of or based upon: (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto) pursuant to which the Registrable Securities were registered under the Securities Act, including all documents incorporated therein by reference, or in any Prospectus (or any amendment or supplement thereto), including all documents incorporated therein by reference, (ii) the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or (iii) any other violation or alleged violation by the Company (or any of its Affiliates) of the Securities Act, the Exchange Act, any state securities law, or any rule or regulation promulgated under the Securities Act, the Exchange Act, or any state securities law, relating to a Registration Statement, Prospectus or amendment or supplement thereto filed in accordance with this Agreement.

(b) against any and all loss, liability, claim, damage, action, cost, judgment and expense whatsoever (including reasonable fees, expenses and disbursements of attorneys and other professionals), as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; and
(c) against any and all cost or expense whatsoever, as incurred (including reasonable fees, expenses and disbursements of attorneys and other professionals), reasonably incurred in investigating, preparing, defending against or participating in (as a witness or otherwise) any litigation, or investigation or proceeding by any third party or governmental agency or body, commenced or threatened, in each case whether or not a party, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under Sections 4.1(a) or 4.1(b) above;
provided, however, that the indemnity provided pursuant to this Section 4.1 does not apply to the Buyer with respect to any loss, liability, claim, damage, action, cost, judgment or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in good faith reliance upon and in conformity with written information furnished to the Company by the Buyer expressly for use in the Registration Statement (or any amendment thereto) or a Prospectus (or any amendment or supplement thereto), to the extent incorporated therein.
4.2 Indemnification by Buyer.   The Buyer agrees to indemnify and hold harmless the Company, and each of its directors and officers (including each director and officer of the Company who signed a Registration Statement), and each Person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, solely with respect to information provided by the Buyer referred to in the proviso to this Section 4.2, as follows:
(a) against any and all loss, liability, claim, damage, action, cost, judgment and expense whatsoever, as incurred, arising out of or based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto) pursuant to which the Registrable Securities of the Buyer were registered under the Securities Act, including all documents incorporated therein by reference, or in any Prospectus (or any amendment or supplement thereto), including all documents incorporated therein by reference, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading;
(b) against any and all loss, liability, claim, damage, judgment and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, if such settlement is effected with the written consent of the Buyer; and
(c) against any and all expense whatsoever, as incurred (including reasonable fees and disbursements of counsel), reasonably incurred in investigating, preparing, defending against or participating in (as a witness or otherwise) any litigation, or investigation or proceeding by any governmental agency or body, commenced or threatened, in each case whether or not a party, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under Sections 4.2(a) or 4.2(b) above;
provided, however, that the indemnity provided pursuant to this Section 4.2 shall only apply with respect to any loss, liability, claim, damage, action, cost judgment or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in good faith reliance upon and in conformity with written information furnished to the Company by the Buyer expressly for use in the Registration Statement (or any amendment thereto) or the Prospectus (or any amendment or supplement thereto), to the extent incorporated therein. Notwithstanding the provisions of this Section 4.2, the Buyer and any permitted assignee shall not be required to indemnify the Company, its officers, directors or control

TABLE OF CONTENTS
persons with respect to any amount in excess of the amount of the total net proceeds to the Buyer or such permitted assignee, as the case may be, from sales of the Registrable Securities of the Buyer under the Registration Statement or Prospectus, as applicable, that is the subject of the indemnification claim.
4.3 Conduct of Indemnification Proceedings.   An indemnified party hereunder shall give reasonably prompt notice to the indemnifying party of any action or proceeding commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify the indemnifying party (i) shall not relieve it from any liability which it may have under the indemnity agreement provided in Section 4.1 or 4.2 above, unless and only to the extent it did not otherwise learn of such action and the lack of notice by the indemnified party results in the forfeiture by the indemnifying party of substantial rights and defenses, and (ii) shall not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided under Section 4.1 or 4.2 above and the contribution obligation provided in Section 4.4 below. If the indemnifying party so elects within a reasonable time after receipt of such notice, the indemnifying party may assume the defense of such action or proceeding at such indemnifying party’s own expense with counsel chosen by the indemnifying party and approved by the indemnified party, which approval shall not be unreasonably withheld; provided, however, that the indemnifying party will not settle, compromise or consent to the entry of any judgment with respect to any such action or proceeding without the written consent of the indemnified party unless such settlement, compromise or consent secures the unconditional release of the indemnified party and does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party; and provided, further, that, if the indemnified party reasonably determines that a conflict of interest exists where it is advisable for the indemnified party to be represented by separate counsel or that, upon advice of counsel, there may be legal defenses available to it which are different from or in addition to those available to the indemnifying party (or in the situation where the indemnifying party fails to take reasonable steps necessary to defend diligently the action or proceeding within 20 Business Days after receiving notice from the indemnified party that the indemnified party believes the indemnifying party has failed to do so), then the indemnifying party shall not be entitled to assume such defense and the indemnified party shall be entitled to separate counsel at the indemnifying party’s expense, it being understood, however, that the indemnifying party shall not, in connection with any one such action, claim or proceeding or separate but substantially similar or related actions, claims or proceedings in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of more than one additional firm of attorneys (together with appropriate local counsel) at any time for all such indemnified parties. If the indemnifying party is not entitled to assume the defense of such action or proceeding as a result of the second proviso to the preceding sentence, the indemnifying party’s counsel shall be entitled to conduct the indemnifying party’s defense and counsel for the indemnified party shall be entitled to conduct the defense of the indemnified party, it being understood that both such counsel will cooperate with each other to conduct the defense of such action or proceeding as efficiently as possible. If the indemnifying party is not so entitled to assume the defense of such action or does not assume such defense, the indemnifying party will not be liable for any settlement effected without the written consent of the indemnifying party, not to be unreasonably withheld, delayed or conditioned. If an indemnifying party is entitled to assume, and assumes, the defense of such action or proceeding in accordance with this paragraph, the indemnifying party shall not be liable for any fees and expenses of counsel for the indemnified party incurred thereafter in connection with such action or proceeding.
4.4 Contribution.   In order to provide for just and equitable contribution in circumstances in which the indemnity agreement provided for in Sections 4.1 and 4.2 above is for any reason held to be unenforceable by a court of competent jurisdiction to any indemnified party although applicable in accordance with its terms, the Company and the Buyer shall contribute to the aggregate losses, liabilities, claims, damages, actions, costs, judgments and expenses of the nature contemplated by such indemnity agreement incurred by the Company and the Buyer, in such proportion as is appropriate to reflect the relative fault of the Company on the one hand and the Buyer on the other hand, in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages, actions, costs, judgments or expenses. The relative fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether the action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, relates to information supplied by the indemnifying party or the indemnified party (and, with respect to Buyer, only written
A-216

TABLE OF CONTENTS
information expressly provided for use in the Registration Statement (or any amendment thereto) or the Prospectus (or any amendment or supplement thereto), to the extent incorporated therein), and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action.
The parties hereto agree that it would not be just or equitable if contribution pursuant to this Section 4.4 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. Notwithstanding the provisions of this Section 4.4, the Buyer shall not be required to contribute any amount in excess of the amount that it would have been obligated to pay by way of indemnification if the indemnification provided for under Section 4.2 had been available under the circumstances.
Notwithstanding the foregoing, no Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any indemnifying party who was not guilty of such fraudulent misrepresentation. For purposes of this Section 4.4, each Person, if any, who controls the Buyer within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and any of their partners, members, officers, directors, employees, agents or representatives, shall have the same rights to contribution as the Buyer, and each director of the Company, each officer of the Company who signed a Registration Statement and each Person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Company.
In addition, no Person shall be obligated to contribute hereunder for any amounts in payment for any settlement of any action or claim, effected without such Person’s written consent, which shall not be unreasonably withheld.
4.5 Survival.   The indemnification and contribution provisions in this Section 4 shall be a continuing right and shall survive the registration and sale of any securities by any Person entitled to indemnification or contribution, as applicable hereunder, and the expiration or termination of this Agreement.
Section 5. Registration Expenses
The Company shall pay all expenses incident to the performance by the Company of its registration obligations under Sections 2 and 3 above, including (i) all expenses incurred in connection with the preparation, printing and distribution of any Registration Statement and Prospectus and all amendments and supplements thereto, (ii) SEC and state securities registration, listing and filing fees, (iii) all fees and expenses of complying with securities or “blue sky” laws (including reasonable fees and disbursements of counsel for the Buyer in connection with “blue sky” qualifications of the securities and determination of their eligibility for investment under the laws of such jurisdictions), (iv) all FINRA fees and fees of any applicable stock exchange, (v) fees and disbursements of counsel for the Company and fees and expenses for the independent certified public accountants retained by the Company (including the expenses or costs associated with the delivery of any opinions or comfort letters), (vi) all internal expenses of the Company (including all salaries and expenses of its officers and employees performing legal or accounting duties); (vii) the fees and expenses of any Person, including special experts, retained by the Company in connection with the preparation of any Registration Statement; and (viii) the fees and disbursements of counsel representing the Buyer registering Registrable Securities pursuant to the Registration Statement and/or participating in the offering, as applicable. The Buyer shall be responsible for the payment of any brokerage and sales commissions, fees and disbursements of the Buyer’s accountants and other advisors (other than legal counsel to the Buyer), and any transfer taxes relating to the sale or disposition of the Registrable Securities by the Buyer pursuant to this Agreement. The Company shall have no obligation to pay any other costs or expenses incurred by the Buyer, including underwriting discounts or selling commissions attributable to the Registrable Securities being sold by the Buyer thereof, which underwriting discounts or selling commissions shall be borne by the Buyer. In addition, in an underwritten offering, all selling stockholders and the Company shall bear the expenses of the underwriters, pro rata, in proportion to the respective amount of shares each sells in such offering.
Section 6. Rule 144 Compliance
The Company shall use commercially reasonable efforts to file as and when applicable, on a timely basis, all reports required to be filed by it under the Exchange Act. The Company shall use commercially
A-217

TABLE OF CONTENTS
reasonable efforts to make and keep current public information available as specified in paragraph (c) of Rule 144 (or any successor rule) promulgated under the Securities Act. The Company shall use commercially reasonable efforts to take such further action as may be reasonably required from time to time to enable the Buyer to Transfer Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 or any other exemption from registration. Upon the request of the Buyer, the Company will deliver to the Buyer a written statement as to whether it has complied with such requirements and, if not, the specifics thereof, as well as any such other information as may be reasonably requested to allow the Buyer to sell its Registrable Securities pursuant to Rule 144. In connection with any Transfer of Registrable Securities by the Buyer pursuant to Rule 144 promulgated under the Securities Act, the Company shall cooperate with the Buyer to facilitate the timely preparation and delivery of certificates representing the Registrable Securities to be sold and not bearing any Securities Act legend, and enable certificates for such Registrable Securities to be for such number of shares and registered in such names as the Buyer may reasonably request at least five Business Days prior to any sale of Registrable Securities hereunder or, if practicable, and at the request of the Buyer, have such Registrable Securities delivered electronically via DWAC through the Depository Trust Company.

The remaining provisions of this Agreement will continue to be binding and in full force and effect.
7.8 Assignment.   No party hereto may assign, in whole or in part, or delegate all or any part of its rights, interests or obligations under this Agreement without the prior written consent of the other party.

Each of the parties hereto (i) agrees that it shall not oppose the granting of any such relief and (ii) hereby irrevocably waives any requirement for the security or posting of any bond in connection with any such relief  (it is understood that clause (i) of this sentence is not intended to, and shall not, preclude any party hereto from litigating on the merits the substantive claim to which such remedy relates).
7.11 Submission to Jurisdiction.   Each of the parties hereto irrevocably agrees that any Proceeding with respect to this Agreement and the rights and obligations arising hereunder, or for recognition and enforcement of any judgment in respect of this Agreement and the rights and obligations arising hereunder brought by any other party hereto or its successors or assigns shall be brought and determined exclusively in the Court of Chancery of the State of Delaware, or in the event (but only in the event) that such court does not have subject matter jurisdiction over such action or proceeding, in the federal courts sitting in the State of Delaware.

or to such other address as may be hereafter communicated in writing by the parties in a notice given in accordance with this Section 8(d), which address shall then apply to the respective notice provisions of the SPMA and all other Ancillary Agreements.
(e) Public Announcements.   Except as required by Legal Requirements or by the requirements of any stock exchange on which the securities of a party hereto or any of its Affiliates are listed, no party to this General Release will make, or cause to be made, any press release or public announcement in respect of this General Release or the transactions contemplated hereby or otherwise communicate with any news media with respect to the foregoing without prior notification to the other parties, and the parties to this General Release will consult with each other and cooperate as to the form, timing and contents of any such press release, public announcement or disclosure.
(f) Severability.   Each provision of this General Release will be interpreted in such manner as to be effective and valid under applicable Legal Requirements, but if any provision of this General Release is found to be unenforceable or invalid under applicable Legal Requirements, such provision will be ineffective only to the extent of such unenforceability or invalidity, and the parties will negotiate in good faith to modify this General Release so that the unenforceable or invalid provision is replaced by such valid and enforceable provision which the parties consider, in good faith, to match as closely as possible the invalid or unenforceable provision and to achieve the same or a similar economic effect and to give effect to the parties’ original intent. The remaining provisions of this General Release will continue to be binding and in full force and effect.
(g) Assignment.   No party hereto may assign, in whole or in part, or delegate all or any part of its rights, interests or obligations under this General Release without the prior written consent of the other party. Any assignment or delegation made without such consent will be void. Notwithstanding the foregoing, Buyer shall be entitled to (a) assign its rights under this General Release to any one of its Affiliates, and (b) assign any or all of its rights and obligations under this General Release (in whole or in part) as collateral security in a financing transaction.
(h) Governing Law.   This General Release and any claims or causes of action pursuant to it will be governed by and construed in accordance with the laws of the State of Delaware, without regard for its principles of conflict of laws.
(i) Specific Performance.   Each party acknowledges and agrees that the other party would be irreparably damaged if the provisions of this General Release are not performed in accordance with their terms and that any breach of this General Release and the non-consummation of the transactions contemplated hereby by either party could not be adequately compensated in all cases by monetary damages alone. Accordingly, in addition to any remedy to which such other party may be entitled under Section 8(j), provisional measures and injunctive relief necessary to protect the possibility of each party to seek specific performance from the other from the tribunal referred to in Section 8(j) can be sought from any court of competent jurisdiction. Each of the parties hereto (i) agrees that it shall not oppose the granting of any such relief and (ii) hereby irrevocably waives any requirement for the security or posting of any bond in connection with any such relief  (it is understood that clause (i) of this sentence is not intended to, and shall not, preclude any party hereto from litigating on the merits the substantive claim to which such remedy relates).
(j) Submission to Jurisdiction.   Each of the parties hereto irrevocably agrees that any Proceeding with respect to this General Release and the rights and obligations arising hereunder, or for recognition and enforcement of any judgment in respect of this General Release and the rights and obligations arising hereunder brought by any other party hereto or its successors or assigns, shall be brought and determined exclusively in the Court of Chancery of the State of Delaware, or in the event (but only in the event) that such court does not have subject matter jurisdiction over such action or proceeding, in the federal courts sitting in the State of Delaware. Each of the parties hereto agrees that mailing of process or other papers in connection with any such action or proceeding in the manner provided in Section 8(d) or in such other manner as may be permitted by applicable Legal Requirements, will be valid and sufficient service thereof. Each of the parties hereto hereby irrevocably submits with regard to any such action or proceeding for itself and in respect of its property, generally and unconditionally, to the personal jurisdiction of the aforesaid courts and agrees that it will not bring any action relating
A-228

TABLE OF CONTENTS
to this General Release or any of the transactions contemplated by this General Release in any court or tribunal other than the aforesaid courts. Each of the parties hereto hereby irrevocably waives, and agrees not to assert, by way of motion, as a defense, counterclaim, or otherwise, in any action or proceeding with respect to this General Release and the rights and obligations arising hereunder, or for recognition and enforcement of any judgment in respect of this General Release and the rights and obligations arising hereunder: (a) any claim that it is not personally subject to the jurisdiction of the above named courts for any reason other than the failure to serve process in accordance with this Section 8(j); (b) any claim that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise); and (c) to the fullest extent permitted by the applicable Legal Requirements, any claim that (i) the suit, action or proceeding in such court is brought in an inconvenient forum, (ii) the venue of such suit, action or proceeding is improper, or (iii) this General Release, or the subject matter hereof, may not be enforced in or by such courts.
(k) Waiver of Jury Trial.   EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES AND, THEREFORE, EACH SUCH PARTY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LEGAL ACTION ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. EACH PARTY TO THIS AGREEMENT CERTIFIES AND ACKNOWLEDGES THAT: (A) NO REPRESENTATIVE OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT SEEK TO ENFORCE THE FOREGOING WAIVER IN THE EVENT OF A LEGAL ACTION; (B) SUCH PARTY HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER; (C) SUCH PARTY MAKES THIS WAIVER VOLUNTARILY; AND (D) SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 8(k).
(l) Waiver.   Any term or condition of this General Release may be waived at any time by the party that is entitled to the benefit thereof, but no such waiver shall be effective unless set forth in a written instrument duly executed by or on behalf of the party waiving such term or condition, and no waiver by any party of any default, misrepresentation, or breach of warranty or covenant hereunder, shall be deemed to extend to any prior or subsequent default, misrepresentation, or breach of warranty, covenant or agreement hereunder or affect in any way any rights arising by virtue of any such prior or subsequent occurrence. No failure or delay of any party in exercising any right or remedy hereunder shall operate as a waiver thereof, and no waiver by any party of any term or condition of this General Release, in any one or more instances, shall be deemed to be or construed as a waiver of the same or any other term or condition of this General Release on any future occasion.
(m) Counterparts; Facsimile Signature.   This General Release may be executed in one (1) or more counterparts, by original or facsimile (or other such electronically transmitted) signature, each of which will be deemed an original, but all of which will constitute one and the same instrument.

The Board of Directors
Avenue Therapeutics, Inc.
2 Gansevoort Street, 9th Floor
New York, NY 10014
Members of the Board:
You have asked Oppenheimer & Co. Inc. (“Oppenheimer”) to render a written opinion (the “Opinion”) to the Board of Directors of Avenue Therapeutics, Inc. (“Avenue”) as to the fairness, from a financial point of view, to the holders of Avenue Common Stock (as defined below) (excluding Fortress Biotech, Inc. (“Fortress”), Invagen Pharmaceuticals Inc. (“Invagen”), Madison Pharmaceuticals Inc. (“Merger Sub”) and any of their respective affiliates) of the Per Share Merger Consideration (as defined below) provided for in a Stock Purchase and Merger Agreement proposed to be entered into by Avenue, Invagen and Merger Sub (such agreement, the “Agreement”). The Agreement provides for, among other things, the merger of Merger Sub with and into Avenue (the “Merger”) pursuant to which each outstanding share of the common stock, par value $0.0001 per share, of Avenue (“Avenue Common Stock”) not owned by Invagen, Merger Sub, or Avenue or any of their respective wholly owned subsidiaries will be converted into the right to receive (a) its pro rata share (the “Per Share Closing Consideration”) of  $180,000,000 in cash (the “Gross Amount”), minus the amount of the indebtedness of Avenue, certain Merger-related charges and expenses, a $3 million development milestone payment that would be payable by Avenue pursuant to its licensing agreement with Revogenex Ireland Limited and a $2 million payment that would be payable by Avenue pursuant to its manufacturing agreement with Zaklady Farmaceutyczne “POLPHARMA” S.A., all as described in the Agreement (such deductions to the Gross Amount, the “Closing Consideration Adjustments”), and (b) its pro rata share (the “Per Share Contingent Consideration”) of the contingent cash payments relating to the future net sales of Avenue’s IV Tramadol (the “Product”) from the closing of the Merger until December 31, 2036 (such period, the “CVR Period” and, such payments, the “CVR Payments”) pursuant to a Contingent Value Rights Agreement proposed to be entered into by Avenue and a specified rights agent (such agreement, the “CVR Agreement”). The Per Share Closing Consideration and the Per Share Contingent Consideration, taken together, are referred to herein as the “Per Share Merger Consideration.”
The Agreement also provides that (i) prior to and as a closing condition of the Merger, Avenue will issue and sell to Invagen a number of shares of Avenue Common Stock representing 33.3% of the Fully Diluted Capitalization (as defined in the Agreement) for $35,000,000 in cash (the “Stock Purchase”) and (ii) the obligations of Invagen to consummate the Merger will be further conditioned upon, among other things, FDA approval of the Product on or before December 1, 2020 and certain labelling, classification and other development milestones involving the Product (such FDA approval and other milestones, collectively, the “Development Milestones”).
In arriving at our Opinion, we:
(a)
Reviewed final execution versions of the Agreement and the CVR Agreement;
(b)
Reviewed publicly available audited financial statements of Avenue as of December 31, 2016 and December 31, 2017, for the period from February 9, 2015 (inception) through December 31, 2015, and for the fiscal years ended December 31, 2016 and December 31, 2017, and publicly available unaudited financial statements of Avenue as of, and for the six months ended, June 30, 2017 and June 30, 2018;

The Board of Directors

Page 2
(c)
Reviewed financial forecasts and estimates relating to Avenue (giving effect to the achievement of the Development Milestones) prepared by the management of Avenue, including estimates of the CVR Payments;
(d)
Reviewed estimates of the Closing Consideration Adjustments provided to or discussed with us by the management of Avenue;
(e)
Held discussions with the senior management team of Avenue with respect to the business and prospects of Avenue, including the liquidity needs of, and capital resources available to, Avenue, and the results of Avenue’s solicitation of third parties regarding a possible acquisition of all or a part of Avenue;
(f)
Reviewed and analyzed certain publicly available financial information for companies that we deemed relevant in evaluating Avenue;
(g)
Analyzed the estimated present value of the future cash flows of Avenue (giving effect to the achievement of the Development Milestones) and the CVR Payments based on financial forecasts and estimates prepared by the management of Avenue;
(h)
Reviewed historical market prices and trading volumes for Avenue Common Stock;
(i)
Reviewed other public information concerning Avenue; and
(j)
Performed such other analyses, reviewed such other information and considered such other factors as we deemed appropriate.
In rendering our Opinion, we assumed and relied upon, without independent verification or investigation, the accuracy and completeness of all of the financial and other data and information provided to or discussed with us by Avenue and its employees, representatives and affiliates or otherwise reviewed by us. With respect to the financial forecasts and estimates relating to Avenue (including estimates of the CVR Payments) and estimates of the Closing Consideration Adjustments referred to above, we have assumed, at Avenue’s direction, and without independent verification or investigation, that such forecasts and estimates have been prepared reasonably and on bases reflecting the best available information, estimates and judgments of the management of Avenue as to the future financial condition and operating results of Avenue (giving effect to the achievement of the Development Milestones) and the other matters covered thereby, that the financial results reflected in the financial forecasts and estimates relating to Avenue referred to above will be achieved at the times and in the amounts projected, and that any differences between the actual CVR Payments and Closing Consideration Adjustments and the estimates thereof referred to above will not be material in any respect to our analyses or Opinion. We express no view as to any of the foregoing forecasts or estimates or the assumptions or bases therefor. Among other things, the financial forecasts and estimates relating to Avenue referred to above reflect assumptions regarding future equity financing transactions needed to fund projected cash shortfalls. Avenue has advised us, and we have assumed, at Avenue’s direction, and without independent verification or investigation, that, in the absence of the Stock Purchase and related debt financings to be provided by Invagen, Avenue would be required to pursue external financing alternatives on terms that would likely be no more favorable to Avenue than those of the Stock Purchase and such related debt financings.
At the direction of representatives of Avenue, we also assumed that the final terms of the Agreement and the CVR Agreement will not vary materially from those set forth in the execution versions reviewed by us. We also have assumed, with the consent of Avenue, that the Merger and related transactions (including, without limitation, the Stock Purchase and the related debt financings to be provided by Invagen) will be consummated in accordance with their respective terms without waiver, modification or amendment of any material term, condition or agreement and in compliance with all applicable laws and other requirements and that, in the course of obtaining the necessary regulatory or third party approvals, consents and releases with respect to the Merger or any related transaction, no delay, limitation, restriction or condition will be

imposed that would have an adverse effect on Avenue or the Merger. We have neither made nor obtained any independent evaluations or appraisals of the assets or liabilities, contingent or otherwise, of Avenue. In addition, we have assumed that any further adjustments to the Per Share Merger Consideration pursuant to the Agreement (as to which further adjustments we express no opinion) will not be material in any respect to our analyses or Opinion. We also have assumed that the circumstances under which the CVR Period would terminate prior to December 31, 2036 pursuant to the CVR Agreement will not occur.
We are not expressing any opinion as to the underlying valuation, future performance or long term viability of Avenue, the actual value of Avenue Common Stock when issued in the Stock Purchase or the price at which Avenue Common Stock will trade at any time. We were not requested to, and we did not, participate in the negotiation or structuring of the Merger or any related transaction. In connection with our engagement, we were not requested to, and we did not, solicit third party indications of interest in the possible acquisition of all or a part of Avenue. We express no view as to, and our Opinion does not address, any terms or other aspects or implications of the Merger (other than the Per Share Merger Consideration to the extent expressly specified herein) or any related transaction or any aspect or implication of any other agreement, arrangement or understanding entered into in connection with the Merger or any related transaction or otherwise, including, without limitation, the form or structure of the Per Share Merger Consideration (including the allocation thereof between the Per Share Closing Consideration and the Per Share Contingent Consideration and the definitions and/or calculations agreed upon by Avenue and Invagen for each of the Consideration Adjustments, the CVR Payments, the Per Share Closing Consideration and the Per Share Contingent Consideration), any consideration to be paid or received in, or any other terms of, the Stock Purchase, the related financings to be provided by Invagen or the contemplated waiver and termination agreement, restrictive covenant agreement and indemnification agreement to be entered into by Fortress, the treatment in the Merger of Avenue’s Class A Preferred Stock, stock options, restricted shares or restricted share units, or the fairness of the amount or nature of the compensation resulting from the Merger to any individual officers, directors or employees of Avenue, or class of such persons, relative to the Per Share Merger Consideration. In addition, we express no view as to, and our Opinion does not address, the underlying business decision of Avenue to proceed with or effect the Merger or any related transaction nor does our Opinion address the relative merits of the Merger or any related transaction as compared to any alternative business strategies that might exist for Avenue or the effect of any other transaction in which Avenue might engage. Our Opinion is necessarily based on the information available to us and general economic, financial and stock market conditions and circumstances as they exist and can be evaluated by us on the date hereof. Although subsequent developments may affect this Opinion, we do not have any obligation to update, revise or reaffirm this Opinion.
The issuance of this Opinion was approved by an authorized committee of Oppenheimer. As part of our investment banking business, we are regularly engaged in valuations of businesses and securities in connection with acquisitions and mergers, underwritings, secondary distributions of securities, private placements and valuations for other purposes.
We have been engaged by Avenue in connection with the Merger solely for purposes of providing this Opinion and will receive a fee for our services upon delivery of this Opinion. We and our affiliates in the past have performed investment banking and other services for Avenue unrelated to the Merger, for which services we and our affiliates have received compensation, including, during the two-year period preceding this Opinion, having acted as sole book-running manager in connection with the initial public offering of Avenue in 2017. In the ordinary course of business, we and our affiliates may actively trade securities of Avenue for our and our affiliates’ own accounts and for the accounts of customers and, accordingly, may at any time hold a long or short position in such securities.

Annex C​
SECTION 262 OF THE DELAWARE GENERAL CORPORATE LAW
§ 262. Appraisal rights
(a)
Any stockholder of a corporation of this State who holds shares of stock on the date of the making of a demand pursuant to subsection (d) of this section with respect to such shares, who continuously holds such shares through the effective date of the merger or consolidation, who has otherwise complied with subsection (d) of this section and who has neither voted in favor of the merger or consolidation nor consented thereto in writing pursuant to § 228 of this title shall be entitled to an appraisal by the Court of Chancery of the fair value of the stockholder’s shares of stock under the circumstances described in subsections (b) and (c) of this section. As used in this section, the word “stockholder” means a holder of record of stock in a corporation; the words “stock” and “share” mean and include what is ordinarily meant by those words; and the words “depository receipt” mean a receipt or other instrument issued by a depository representing an interest in 1 or more shares, or fractions thereof, solely of stock of a corporation, which stock is deposited with the depository.
(b)
Appraisal rights shall be available for the shares of any class or series of stock of a constituent corporation in a merger or consolidation to be effected pursuant to § 251 (other than a merger effected pursuant to § 251(g) of this title), § 252, § 254, § 255, § 256, § 257, § 258, § 263 or § 264 of this title:
(1)
Provided, however, that, except as expressly provided in § 363(b) of this title, no appraisal rights under this section shall be available for the shares of any class or series of stock, which stock, or depository receipts in respect thereof, at the record date fixed to determine the stockholders entitled to receive notice of the meeting of stockholders to act upon the agreement of merger or consolidation (or, in the case of a merger pursuant to § 251(h), as of immediately prior to the execution of the agreement of merger), were either: (i) listed on a national securities exchange or (ii) held of record by more than 2,000 holders; and further provided that no appraisal rights shall be available for any shares of stock of the constituent corporation surviving a merger if the merger did not require for its approval the vote of the stockholders of the surviving corporation as provided in § 251(f) of this title.
(2)
Notwithstanding paragraph (b)(1) of this section, appraisal rights under this section shall be available for the shares of any class or series of stock of a constituent corporation if the holders thereof are required by the terms of an agreement of merger or consolidation pursuant to §§ 251, 252, 254, 255, 256, 257, 258, 263 and 264 of this title to accept for such stock anything except:
a.
Shares of stock of the corporation surviving or resulting from such merger or consolidation, or depository receipts in respect thereof;
b.
Shares of stock of any other corporation, or depository receipts in respect thereof, which shares of stock (or depository receipts in respect thereof) or depository receipts at the effective date of the merger or consolidation will be either listed on a national securities exchange or held of record by more than 2,000 holders;

(4)
In the event of an amendment to a corporation’s certificate of incorporation contemplated by § 363(a) of this title, appraisal rights shall be available as contemplated by § 363(b) of this title, and the procedures of this section, including those set forth in subsections (d) and (e) of this section, shall apply as nearly as practicable, with the word “amendment” substituted for the words “merger or consolidation”, and the word “corporation” substituted for the words “constituent corporation” and/or “surviving or resulting corporation.”
(c)
Any corporation may provide in its certificate of incorporation that appraisal rights under this section shall be available for the shares of any class or series of its stock as a result of an amendment to its certificate of incorporation, any merger or consolidation in which the corporation is a constituent corporation or the sale of all or substantially all of the assets of the corporation. If the certificate of incorporation contains such a provision, the provisions of this section, including those set forth in subsections (d), (e), and (g) of this section, shall apply as nearly as is practicable.
(d)
Appraisal rights shall be perfected as follows:
(1)
If a proposed merger or consolidation for which appraisal rights are provided under this section is to be submitted for approval at a meeting of stockholders, the corporation, not less than 20 days prior to the meeting, shall notify each of its stockholders who was such on the record date for notice of such meeting (or such members who received notice in accordance with § 255(c) of this title) with respect to shares for which appraisal rights are available pursuant to subsection (b) or (c) of this section that appraisal rights are available for any or all of the shares of the constituent corporations, and shall include in such notice a copy of this section and, if 1 of the constituent corporations is a nonstock corporation, a copy of § 114 of this title. Each stockholder electing to demand the appraisal of such stockholder’s shares shall deliver to the corporation, before the taking of the vote on the merger or consolidation, a written demand for appraisal of such stockholder’s shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such stockholder’s shares. A proxy or vote against the merger or consolidation shall not constitute such a demand. A stockholder electing to take such action must do so by a separate written demand as herein provided. Within 10 days after the effective date of such merger or consolidation, the surviving or resulting corporation shall notify each stockholder of each constituent corporation who has complied with this subsection and has not voted in favor of or consented to the merger or consolidation of the date that the merger or consolidation has become effective; or
(2)
If the merger or consolidation was approved pursuant to § 228, § 251(h), § 253, or § 267 of this title, then either a constituent corporation before the effective date of the merger or consolidation or the surviving or resulting corporation within 10 days thereafter shall notify each of the holders of any class or series of stock of such constituent corporation who are entitled to appraisal rights of the approval of the merger or consolidation and that appraisal rights are available for any or all shares of such class or series of stock of such constituent corporation, and shall include in such notice a copy of this section and, if 1 of the constituent corporations is a nonstock corporation, a copy of  § 114 of this title. Such notice may, and, if given on or after the effective date of the merger or consolidation, shall, also notify such stockholders of the effective date of the merger or consolidation. Any stockholder entitled to appraisal rights may, within 20 days after the date of mailing of such notice or, in the case of a merger approved pursuant to § 251(h) of this title, within the later of the consummation of the offer contemplated by § 251(h) of this title and 20 days after the date of mailing of such notice, demand in writing from the surviving or resulting corporation the appraisal of such holder’s shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such holder’s shares. If such notice did not notify stockholders of the effective date of the merger or consolidation, either (i) each such constituent corporation shall send a second notice before the effective date of the merger or consolidation notifying
C-2

TABLE OF CONTENTS
each of the holders of any class or series of stock of such constituent corporation that are entitled to appraisal rights of the effective date of the merger or consolidation or (ii) the surviving or resulting corporation shall send such a second notice to all such holders on or within 10 days after such effective date; provided, however, that if such second notice is sent more than 20 days following the sending of the first notice or, in the case of a merger approved pursuant to § 251(h) of this title, later than the later of the consummation of the offer contemplated by § 251(h) of this title and 20 days following the sending of the first notice, such second notice need only be sent to each stockholder who is entitled to appraisal rights and who has demanded appraisal of such holder’s shares in accordance with this subsection. An affidavit of the secretary or assistant secretary or of the transfer agent of the corporation that is required to give either notice that such notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein. For purposes of determining the stockholders entitled to receive either notice, each constituent corporation may fix, in advance, a record date that shall be not more than 10 days prior to the date the notice is given, provided, that if the notice is given on or after the effective date of the merger or consolidation, the record date shall be such effective date. If no record date is fixed and the notice is given prior to the effective date, the record date shall be the close of business on the day next preceding the day on which the notice is given.
(e)
Within 120 days after the effective date of the merger or consolidation, the surviving or resulting corporation or any stockholder who has complied with subsections (a) and (d) of this section hereof and who is otherwise entitled to appraisal rights, may commence an appraisal proceeding by filing a petition in the Court of Chancery demanding a determination of the value of the stock of all such stockholders. Notwithstanding the foregoing, at any time within 60 days after the effective date of the merger or consolidation, any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party shall have the right to withdraw such stockholder’s demand for appraisal and to accept the terms offered upon the merger or consolidation. Within 120 days after the effective date of the merger or consolidation, any stockholder who has complied with the requirements of subsections (a) and (d) of this section hereof, upon written request, shall be entitled to receive from the corporation surviving the merger or resulting from the consolidation a statement setting forth the aggregate number of shares not voted in favor of the merger or consolidation (or, in the case of a merger approved pursuant to § 251(h) of this title, the aggregate number of shares (other than any excluded stock (as defined in § 251(h)(6)d. of this title)) that were the subject of, and were not tendered into, and accepted for purchase or exchange in, the offer referred to in § 251(h)(2)), and, in either case, with respect to which demands for appraisal have been received and the aggregate number of holders of such shares. Such written statement shall be mailed to the stockholder within 10 days after such stockholder’s written request for such a statement is received by the surviving or resulting corporation or within 10 days after expiration of the period for delivery of demands for appraisal under subsection (d) of this section hereof, whichever is later. Notwithstanding subsection (a) of this section, a person who is the beneficial owner of shares of such stock held either in a voting trust or by a nominee on behalf of such person may, in such person’s own name, file a petition or request from the corporation the statement described in this subsection.
(f)
Upon the filing of any such petition by a stockholder, service of a copy thereof shall be made upon the surviving or resulting corporation, which shall within 20 days after such service file in the office of the Register in Chancery in which the petition was filed a duly verified list containing the names and addresses of all stockholders who have demanded payment for their shares and with whom agreements as to the value of their shares have not been reached by the surviving or resulting corporation. If the petition shall be filed by the surviving or resulting corporation, the petition shall be accompanied by such a duly verified list. The Register in Chancery, if so ordered by the Court, shall give notice of the time and place fixed for the hearing of such petition by registered or certified mail to the surviving or resulting corporation and to the stockholders shown on the list at the addresses therein stated. Such notice shall also be given by 1 or more publications at least 1 week before the day of the hearing, in a newspaper of general circulation published in
C-3

TABLE OF CONTENTS
the City of Wilmington, Delaware or such publication as the Court deems advisable. The forms of the notices by mail and by publication shall be approved by the Court, and the costs thereof shall be borne by the surviving or resulting corporation.
(g)
At the hearing on such petition, the Court shall determine the stockholders who have complied with this section and who have become entitled to appraisal rights. The Court may require the stockholders who have demanded an appraisal for their shares and who hold stock represented by certificates to submit their certificates of stock to the Register in Chancery for notation thereon of the pendency of the appraisal proceedings; and if any stockholder fails to comply with such direction, the Court may dismiss the proceedings as to such stockholder. If immediately before the merger or consolidation the shares of the class or series of stock of the constituent corporation as to which appraisal rights are available were listed on a national securities exchange, the Court shall dismiss the proceedings as to all holders of such shares who are otherwise entitled to appraisal rights unless (1) the total number of shares entitled to appraisal exceeds 1% of the outstanding shares of the class or series eligible for appraisal, (2) the value of the consideration provided in the merger or consolidation for such total number of shares exceeds $1 million, or (3) the merger was approved pursuant to § 253 or § 267 of this title.
(h)
After the Court determines the stockholders entitled to an appraisal, the appraisal proceeding shall be conducted in accordance with the rules of the Court of Chancery, including any rules specifically governing appraisal proceedings. Through such proceeding the Court shall determine the fair value of the shares exclusive of any element of value arising from the accomplishment or expectation of the merger or consolidation, together with interest, if any, to be paid upon the amount determined to be the fair value. In determining such fair value, the Court shall take into account all relevant factors. Unless the Court in its discretion determines otherwise for good cause shown, and except as provided in this subsection, interest from the effective date of the merger through the date of payment of the judgment shall be compounded quarterly and shall accrue at 5% over the Federal Reserve discount rate (including any surcharge) as established from time to time during the period between the effective date of the merger and the date of payment of the judgment. At any time before the entry of judgment in the proceedings, the surviving corporation may pay to each stockholder entitled to appraisal an amount in cash, in which case interest shall accrue thereafter as provided herein only upon the sum of  (1) the difference, if any, between the amount so paid and the fair value of the shares as determined by the Court, and (2) interest theretofore accrued, unless paid at that time. Upon application by the surviving or resulting corporation or by any stockholder entitled to participate in the appraisal proceeding, the Court may, in its discretion, proceed to trial upon the appraisal prior to the final determination of the stockholders entitled to an appraisal. Any stockholder whose name appears on the list filed by the surviving or resulting corporation pursuant to subsection (f) of this section and who has submitted such stockholder’s certificates of stock to the Register in Chancery, if such is required, may participate fully in all proceedings until it is finally determined that such stockholder is not entitled to appraisal rights under this section.
(i)
The Court shall direct the payment of the fair value of the shares, together with interest, if any, by the surviving or resulting corporation to the stockholders entitled thereto. Payment shall be so made to each such stockholder, in the case of holders of uncertificated stock forthwith, and the case of holders of shares represented by certificates upon the surrender to the corporation of the certificates representing such stock. The Court’s decree may be enforced as other decrees in the Court of Chancery may be enforced, whether such surviving or resulting corporation be a corporation of this State or of any state.
(j)
The costs of the proceeding may be determined by the Court and taxed upon the parties as the Court deems equitable in the circumstances. Upon application of a stockholder, the Court may order all or a portion of the expenses incurred by any stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorney’s fees and the fees and expenses of experts, to be charged pro rata against the value of all the shares entitled to an appraisal.
(k)
From and after the effective date of the merger or consolidation, no stockholder who has demanded appraisal rights as provided in subsection (d) of this section shall be entitled to vote

TABLE OF CONTENTS
such stock for any purpose or to receive payment of dividends or other distributions on the stock (except dividends or other distributions payable to stockholders of record at a date which is prior to the effective date of the merger or consolidation); provided, however, that if no petition for an appraisal shall be filed within the time provided in subsection (e) of this section, or if such stockholder shall deliver to the surviving or resulting corporation a written withdrawal of such stockholder’s demand for an appraisal and an acceptance of the merger or consolidation, either within 60 days after the effective date of the merger or consolidation as provided in subsection (e) of this section or thereafter with the written approval of the corporation, then the right of such stockholder to an appraisal shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery shall be dismissed as to any stockholder without the approval of the Court, and such approval may be conditioned upon such terms as the Court deems just; provided, however that this provision shall not affect the right of any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party to withdraw such stockholder’s demand for appraisal and to accept the terms offered upon the merger or consolidation within 60 days after the effective date of the merger or consolidation, as set forth in subsection (e) of this section.
(l)
The shares of the surviving or resulting corporation to which the shares of such objecting stockholders would have been converted had they assented to the merger or consolidation shall have the status of authorized and unissued shares of the surviving or resulting corporation.

Section 6.10 Specific Performance.   Each party acknowledges and agrees that the other party would be irreparably damaged if the provisions of this Agreement are not performed in accordance with their terms and that any breach of this Agreement and the non-consummation of the transactions contemplated hereby by either party could not be adequately compensated in all cases by monetary damages alone. Accordingly, in addition to any remedy to which such other party may be entitled under Section 6.11, provisional measures and injunctive relief necessary to protect the possibility of each party to seek specific performance from the other from the tribunal referred to in Section 6.11 can be sought from any court of competent jurisdiction. Each of the parties hereto (i) agrees that it shall not oppose the granting of any such relief and (ii) hereby irrevocably waives any requirement for the security or posting of any bond in connection with any such relief  (it is understood that clause (i) of this sentence is not intended to, and shall not, preclude any party hereto from litigating on the merits the substantive claim to which such remedy relates).
Section 6.11 Submission to Jurisdiction.
(a)
Each of the parties hereto irrevocably agrees that any Proceeding with respect to this Agreement and the rights and obligations arising hereunder, or for recognition and enforcement of any judgment in respect of this Agreement and the rights and obligations arising hereunder brought by any other party hereto or its successors or assigns, shall be brought and determined exclusively in the Court of Chancery of the State of Delaware, or in the event (but only in the event) that such court does not have subject matter jurisdiction over such action or proceeding, in the federal courts sitting in the State of Delaware. Each of the parties hereto agrees that mailing of process or other papers in connection with any such action or proceeding in the manner provided in Section 6.4 or in such other manner as may be permitted by applicable Legal Requirements, will be valid and sufficient service thereof. Each of the parties hereto hereby irrevocably submits with regard to any such action or proceeding for itself and in respect of its property, generally and unconditionally, to the personal jurisdiction of the aforesaid courts and agrees that it will not bring any action relating to this Agreement or any of the transactions contemplated by this Agreement in any court or tribunal other than the aforesaid courts. Each of the parties hereto hereby irrevocably waives, and agrees not to assert, by way of motion, as a defense, counterclaim, or otherwise, in any action or proceeding with respect to this Agreement and the rights and obligations arising hereunder, or for recognition and enforcement of any judgment in respect of this Agreement and the rights and obligations arising hereunder: (a) any claim that it is not personally subject to the jurisdiction of the above named courts for any reason other than the failure to serve process in accordance with this Section 6.11; (b) any claim that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise); and (c) to the fullest extent permitted by the applicable Legal Requirements, any claim that (i) the suit, action or proceeding in such court is brought in an inconvenient forum, (ii) the venue of such suit, action or proceeding is improper, or (iii) this Agreement, or the subject matter hereof, may not be enforced in or by such courts.
(b)
All rights of action with respect to enforcement of the Company’s obligations under this Agreement for the benefit of any Holder may only be enforced by the Rights Agent upon the prior written direction of the Majority Holders to the Rights Agent, and any claim, action, suit, audit, investigation or proceeding instituted by the Rights Agent will be brought in its name as the Rights Agent and any recovery in connection therewith will be for the proportionate benefit of all the Holders, as their respective rights or interests may appear on the CVR Register.
