liability company with an address of 1300 Gould Drive, Gainesville, GA 30504 (“Recro Gainesville”), as successor in interest to Recro Technology LLC (f/k/a DV Technology LLC) and a wholly-owned subsidiary of Recro Pharma, Inc., a
Pennsylvania corporation with an address of 490 Lapp Road, Malvern PA 19355 (“Recro Pharma”), and Baudax Bio, Inc., a Pennsylvania corporation, with an address of 490 Lapp Road, Malvern PA 19355 (“Baudax”). 

WHEREAS, APIL and Recro Gainesville (as successor in interest to Recro Technology LLC, who is f/k/a DV Technology LLC) are parties to that
certain Asset Transfer and License Agreement dated April 10, 2015, as amended on December 23, 2015 and December 20, 2018, pursuant to which Recro Gainesville exclusively licenses the Nanotechnology IP and certain Licensed Trademarks
for the Nanotechnology IP for the Meloxicam IV/IM and Meloxicam Parenteral Formulation from APIL (the “Asset Transfer and License Agreement”); 

WHEREAS, Recro Pharma and Baudax are parties to that certain Separation Agreement, dated as of the date hereof, pursuant to which Recro Pharma
will (i) assign, or cause its subsidiaries to assign, certain assets related to the Acute Care Business (as defined in the Separation Agreement) to Baudax (the “Separation”) and (ii) distribute all of the issued and outstanding
common stock of Baudax to Recro Pharma’s shareholders (the “Distribution,” and the effective time of the Distribution, the “Distribution Time”); 

WHEREAS, in order to effect the Separation, effective immediately prior to the Distribution Time (the “Effective Time”), Recro
Gainesville desires to assign, convey, transfer and set over to Baudax certain of Recro Gainesville’s rights, benefits, privileges, interests and obligations under the Asset Transfer and License Agreement and Baudax desires to accept such
assignment, conveyance, transfer and set over from Recro Gainesville and to assume certain of Recro Gainesville’s obligations under the Asset Transfer and License Agreement and to agree to satisfy, pay, perform and discharge, as and when due,
such obligations, in each case, on the terms set forth herein; 
 NOW, THEREFORE, in consideration of the mutual covenants and agreements
contained herein, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties agree as follows: 

1. Effectiveness. This Agreement shall be effective as of the Effective Time. In the event that the Separation does not occur for any
reason, this Agreement will be null and void with no further action required on the part of either party. 
 2. Bifurcation, Partial
Assignment and Assumption. Recro Gainesville hereby irrevocably assigns, conveys and transfers to Baudax all of Recro Gainesville’s rights, benefits, privileges, interests, burdens, obligations and liabilities under the Asset Transfer and
License 












 Agreement to the extent related to the Acute Care Business (whether occurring on, before or after the
Effective Time) including, but not limited to, the rights and obligations set forth in Exhibit A of this Agreement (the “Assigned Rights and Obligations”). Recro Gainesville shall remain responsible for all other rights and
obligations under the Asset Transfer and License Agreement that are not bifurcated, assigned to and/or assumed by Baudax hereunder. APIL agrees and acknowledges that Baudax’s Assigned Rights and Obligations under the Asset Transfer and License
Agreement shall not be affected or limited by a breach of the Asset Transfer and License Agreement by Recro Gainesville. 
 3. Third Party
Beneficiary. In connection with the partial bifurcation, assignment and assumption of the Asset Transfer and License Agreement pursuant to Section 2 above, the parties agree and acknowledge that Baudax Bio is a third party beneficiary of
the Asset Transfer and License Agreement, entitled to enforce the provisions of the Asset Transfer and License Agreement as they relate to Assigned Rights and Obligations. 

4. Mutual Acceptance. Baudax unconditionally accepts the assignment, conveyance and transfer of the Assigned Rights and Obligations and,
without limiting the foregoing, assumes and agrees to satisfy, pay, perform and discharge, as and when due, all of the Assumed Obligations (as defined in Exhibit A of this Agreement) whether occurring on, before or after the Effective Time. 

5. Consent and Acknowledgment. APIL hereby consents to the partial bifurcation of the Asset Transfer and License Agreement as it relates
to the Assigned Rights and Obligations and the assignment by Recro Gainesville to Baudax of such Assigned Rights and Obligations. APIL hereby agrees that this Agreement satisfies any notice, consent or other procedural requirements under the Asset
Transfer and License Agreement with respect to the assignment of the Assigned Rights and Obligations and acknowledges and agrees that, notwithstanding Section 2.4 of Exhibit D to the Asset Transfer and License Agreement, APIL shall have no
further right of recourse against Recro Gainesville under the Asset Transfer and License Agreement with respect to the Assigned Rights and Obligations for periods after the Effective Time. APIL agrees to treat the Asset Transfer and License
Agreement as partially bifurcated and assigned as set forth in Sections 2 and 3 hereof. Without limiting the generality of the foregoing, APIL shall communicate directly with Baudax as a third party beneficiary to the Asset Transfer and License
Agreement with respect to the Assigned Rights and Obligations. 
 6. Disclaimer and Release. With respect to all Assigned Rights and
Obligations under the Asset Transfer and License Agreement that are assigned to and assumed by Baudax hereunder, Recro Gainesville hereby, without any further action, disclaims and is released from the Assigned Rights and Obligations under the Asset
Transfer and License Agreement, and Baudax shall have the sole right and responsibility in connection therewith. Recro Gainesville’s rights and obligations under the Asset Transfer and License Agreement shall not be affected or limited by a
breach of the Asset Transfer and License Agreement by Baudax. 
 7. Further Actions. Each of the parties hereto agrees to execute,
acknowledge and deliver, or cause the execution, acknowledgement and delivery of, such further documents and instruments and to perform such other reasonable actions as may reasonably be requested by a party hereto in order to effect the purposes of
this Agreement.

 8. Assignment. This Agreement shall inure to the benefit of the parties hereto and
their respective successors and assigns. Baudax may assign all or a portion of its Assigned Rights and Obligations to any purchaser of that portion of its business to which the Asset Transfer and License Agreement relates with the prior written
consent of APIL, which will not be unreasonably withheld, conditioned or delayed. 
 9. Governing Law. This Agreement and the
respective rights, duties and obligations of the parties hereunder shall be governed and construed in accordance with the laws of the State of Delaware, without giving effect to the conflict of laws provisions of that or any other jurisdiction. 

10. Miscellaneous. This Agreement may not be modified except by an instrument in writing executed by the parties hereto. This Agreement
may be executed in one or more counterparts and by facsimile, each of which shall be deemed an original and all of which, taken together, shall constitute one and the same instrument. The waiver by either party of any default, breach, or right of
this Agreement shall not constitute a waiver of any other or subsequent default, breach, or right. Section and paragraph headings in this Agreement are included herein for convenience of reference only and shall not modify, define, expand or limit
any of the terms or provisions of this Agreement. Capitalized terms used herein and not otherwise defined shall have the respective meanings given to them in the Asset Transfer and License Agreement.
