Ascentage and Unity are parties to that certain Compound License Agreement for APG1197 dated January 2, 2019, (the “Original APG-1197 License Agreement”) pursuant to which Ascentage granted Unity exclusive rights to a BCL Compound known as APG-1197 for the prophylaxis and treatment of, and
palliation of symptoms associated with, age related indications other than Oncology Indications. 
 The Parties now wish to amend the
Original APG-1197 License Agreement. Except as expressly modified hereby, the Original APG-1197 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: 
 AGREEMENT
