FIRST AMENDMENT TO APG1252 LICENSE AGREEMENT

This Amendment (the “Amendment”), dated as of March 28, 2018 (the Amendment Effective Date”) is made by and between Ascentage Pharma Group Corp. Ltd., a Hong Kong corporation (“Ascentage”), with a business address at 00/X, XXX XXXXXX, Xxxxxxxxxx Xxxx, Xxxxxxx, Xxxx Xxxx, and Unity Biotechnology, Inc., a Delaware corporation (“Unity”), with a business address at 0000 Xxxxxxxx Xxxx, Xxxxx 000, Xxxxxxxx, Xxxxxxxxxx 00000. Ascentage and Unity are sometimes referred to herein as individually as a “Party” and collectively as the “Parties”.

BACKGROUND

A. The Parties entered into a Compound Library and Option Agreement (the “Library Agreement”) dated February 2, 2016 (the “Original Effective Date”), which granted Unity the right to screen Ascentage’s collection of BCL-2/BCL-xL inhibitor compounds as well as additional BCL-2/BCL-xL inhibitor compounds discovered by Ascentage during the term of the Library Agreement, including pursuant to that certain Research Services Agreement between the Parties dated February 2, 2016 (collectively, the “BCL Compounds”) to identify compounds with potential utility in the treatment of age-related conditions other than Oncology Indications. Defined terms used herein and not otherwise defined shall have the meanings ascribed in the Library Agreement.

B. On the Original Effective Date the Parties also entered the APG1252 License Agreement (the “1252 License Agreement”) pursuant to which Ascentage granted Unity exclusive rights to a BCL Compound known as APG-1252 for the prophylaxis and treatment of, and palliation of symptoms associated with, age related indications other than Oncology Indications.

C. Ascentage is also a party to a License Agreement with the Regents of the University of Michigan (“Michigan”) dated December 1, 2010 (as amended on May 30, 2013, February 2, 2016, May 10, 2017 and June 1, 2017, the “Michigan License Agreement”), pursuant to which Michigan granted Ascentage exclusive rights, with the right to sublicense, under certain Michigan patents which cover, among other things, the BCL Compounds.

D. The Michigan License Agreement provides for Ascentage to pay Michigan twenty percent (20%) of Ascentage’s Gross Sublicensing Revenues (as defined therein) and further provides that in the event a portion of Gross Sublicensing Revenues includes non-cash consideration, the relevant Ascentage sublicensee shall be required to issue such non-cash consideration directly to Michigan.

E. Each of the Library Agreement and the 1252 License Agreement provided for certain payments to be made by Unity to Ascentage in the form of shares of Unity common stock including (i) in each case, an upfront payment that was due within [***] ([***]) days of the Original Effective Date (the “Upfront Equity Payments”), and (ii) in the case of the 1252 License Agreement, additional payments upon the achievement of certain development milestones (the “Milestone Equity Payments” and, together with the Upfront Equity Payments, the “Unity Equity Payments”)

F. Pursuant to the terms of the Michigan License Agreement (i) twenty percent (20%) of each Unity Equity Payment is owed by Ascentage to Michigan as a sublicense fee, and (ii) Ascentage is required to cause Unity to issue such Unity Equity Payments directly to Michigan.

G. On or around the Original Effective Date, in order to enable Ascentage to satisfy its sublicense fee payment obligations to Michigan with respect to the Upfront Equity Payments, the Parties agreed that Unity should issue twenty percent (20%) of the Upfront Equity Payments directly to Michigan. Therefore, Unity bifurcated its issuance of the Upfront Equity Payments and issued eighty

percent (80%) of the shares of common stock to Ascentage and twenty percent (20%) portion of the shares of common stock to Michigan. A schedule of the Upfront Equity Payments that were due and made to each party is set forth on Exhibit A hereto.

H. The Parties now wish to set forth and document their understanding and agreement about the manner in which the Upfront Equity Payments were made as well as the manner in which any additional Milestone Equity Payments will be made in connection under the 1252 License Agreement. Except as expressly modified hereby, the 1252 License Agreement shall continue in full force according to its terms.

NOW, THEREFORE, for and in consideration of the covenants, conditions and undertakings hereinafter set forth, it is agreed by and between the Parties as follows:

(b) On February 17, 2016, pursuant to a separate Restricted Stock Grant Agreement, Unity granted Michigan a total 393,335 shares of Unity common stock, of which 314,668 shares represented Michigan’s twenty percent (20%) portion of the Upfront Equity Payment due under the 1252 License Agreement.
