Effective June 1, 2021, the Company, InvaGen, Fortress and Journey Medical Corporation (“Journey”), a consolidated entity under Fortress, entered into a secondment agreement for a certain Avenue employee to be seconded to Journey. During the secondment, Journey will have the authority to supervise the Avenue employee and will reimburse the Company for the employee’s salary and salary-related costs. The term of this agreement lasts until the approval of IV tramadol by the FDA or until the employee’s services are needed again by the Company. The amounts reimbursable to Avenue are $74,000 and $98,000 for the three and nine months ended September 30, 2021, respectively. The amount due to the Company as of September 30, 2021 that is related to this secondment agreement is $74,000 and is included in "Other receivables - related party" on the Company's condensed balance sheets.

Effective June 24, 2021, Fortress and certain of the Company’s key employees entered into retention agreements (the “Fortress Retention Agreements”) pursuant to which retention bonuses are payable only if the Merger Transaction (as defined in the SPMA) occurs and the applicable employee remains employed by the Company immediately prior to the closing of the Merger Transaction. These Fortress Retention Agreements are effective until the earlier of the consummation of the Merger Transaction or the termination of the SPMA. Amounts potentially payable to these key employees are $2.9 million as of September 30, 2021. On October 7, 2021, an agreement with a fourth key employee was signed with the same terms and conditions as set forth in the Fortress Retention Agreements. The amount potentially payable to this employee is $0.3 million. As the SPMA was terminated on November 1, 2021, there are no amounts payable under the Fortress Retention Agreements.
