Article 11
INDEMNIFICATION

11.1 Unity. Unity agrees to indemnify and defend Ascentage and its directors, officers, employees, agents and their respective successors, heirs and assigns (the “Ascentage Indemnitees”) against any losses, costs, claims, damages, liabilities or expense (including reasonable attorneys’ and professional fees and other expenses of litigation) (collectively, “Liabilities”) arising, directly or indirectly out of or in connection with Third Party claims, suits, actions, demands or judgments, to the extent (a) relating to Licensed Products developed, manufactured, used, sold or otherwise distributed by or on behalf of Unity, its Affiliates, sublicensees or other designees (excluding Ascentage, its Affiliates and licensees) including, without limitation, product liability and patent infringement claims, (b) resulting from a breach by Unity of its representations and warranties under this Agreement, or (c) the exercise of its manufacturing license set forth in Section 2.1.2(b), except, in each case, to the extent such Liabilities result from the negligence or intentional misconduct of Ascentage or Ascentage’s breach of its representations and warranties under this Agreement.

11.2 Ascentage. Ascentage agrees to indemnify and defend Unity and its directors, officers, employees, agents and their respective heirs and assigns (the “Unity Indemnitees”) against any Liabilities arising, directly or indirectly out of or in connection with Third Party claims, suits, actions, demands or judgments, to the extent resulting from (a) a breach by Ascentage of its representations and warranties under this Agreement or (b) the exercise of its manufacturing license set forth in Section 2.1.2(a), except, in each case, to the extent such Liabilities result from the negligence or intentional misconduct of Unity or Unity’s breach of its representations and warranties under this Agreement.

11.3 Procedure. In the event that any party intends to claim indemnification under this Article 11 (each such party, an “Indemnitee”) it shall promptly notify the other Party in writing

22

of such alleged Liability. The indemnifying Party shall have the right to control the defense thereof with counsel of its choice as long as such counsel is reasonably acceptable to Indemnitee; provided, however, that any Indemnitee shall have the right to retain its own counsel at its own expense, for any reason, including if representation of any Indemnitee by the counsel retained by the indemnifying Party would be inappropriate due to actual or potential differing interests between such Indemnitee and any other Party reasonably represented by such counsel in such proceeding. The indemnifying Party shall keep the Indemnitee regularly informed of the status of the defense of any action, claim or liability covered by this Article 11 and shall take into consideration the Indemnitee’s reasonable comments thereon.

INVESTMENT REPRESENTATION STATEMENT

GRANTEE		:		ASCENTAGE PHARMA GROUP CORP LIMITED
COMPANY		:		UNITY BIOTECHNOLOGY, INC.
SECURITY		:		COMMON STOCK
AMOUNT		:		106,667 SHARES
DATE		:		[●]

In connection with the acquisition of the 106,667 shares of the Company’s Common Stock, $0.0001 par value per share (the “Shares”), Ascentage Pharma Group Corp Limited (“Ascentage”) as the undersigned, represent to the Company as follows:

1. The Company may rely on these representations.  Ascentage understands that the Company’s sale of the Shares has not been registered under the Securities Act of 1933, as amended (the “Securities Act”), because the Company believes, relying in part on these representations in this document, that an exemption from such registration requirement is available for such sale.  Ascentage understands that the availability of this exemption depends upon the representations Ascentage am making to the Company in this document being true and correct.

A. Ascentage has conducted its own due diligence examination of the Company’s business, financial condition, results of operations, and prospects and has reviewed the Company’s filings with the United States Securities and Exchange Commission (the “SEC”), in each case, to the extent it deems necessary and in a manner sufficient to enable it to evaluate its purchase of the Shares.  Ascentage understands that its investment in the Shares involves a high degree of risk.  Ascentage has sought such accounting, legal and tax advice as it has considered necessary to make an informed investment decision with respect to its acquisition of the Securities.  Ascentage further represents that it has relied solely upon the aforementioned examination, review and evaluation and has not relied on any representation or action made or taken by Seller or any of its affiliates or any of its or their officers, directors or representatives in connection with such Buyer’s decision to acquire the Securities, other than those expressly set forth herein.  Ascentage understands and agrees that the Company, its affiliates and its and their respective officers, directors and representatives have not made any representation or warranty whatsoever with respect to the business, condition (financial or otherwise), properties, prospects, creditworthiness, status or affairs of the Company, or with respect to the value of the Shares.

2. I am purchasing for investment.  Ascentage is purchasing the Shares solely for investment purposes, and not for further distribution.  The entire legal and beneficial ownership interest in the Shares is being acquired and shall be held solely for Ascentage’s account.  Ascentage is not a party to, and do not presently intend to enter into, any contract or other arrangement with any other person or entity involving the resale, transfer, grant of participation with respect to or other distribution of any of the Shares.  Its investment intent is not limited to any present intention

US-DOCS\106256636.1

to hold the Shares for the minimum capital gains period specified under any applicable tax law, for a deferred sale, for a specified increase or decrease in the market price of the Shares, or for any other fixed period in the future.

3. Ascentage can protect its own interests.  Ascentage can properly evaluate the merits and risks of an investment in the Shares and can protect its own interests in this regard, whether by reason of its own business and financial expertise, the business and financial expertise of certain professional advisors unaffiliated with the Company with whom Ascentage have consulted, or my preexisting business or personal relationship with the Company or any of its officers, directors or controlling persons.

4. Ascentage is informed about the Company.  Ascentage am sufficiently aware of the Company’s business affairs and financial condition to reach an informed and knowledgeable decision to acquire the Shares.  Ascentage has had opportunity to discuss the plans, operations and financial condition of the Company with its officers, directors or controlling persons, and have received all information Ascentage deems appropriate for assessing the risk of an investment in the Shares.

5. Ascentage is an “accredited investor.” Ascentage is an Accredited Investor as defined in Rule 501(a) under the Securities Act.  Ascentage understands and acknowledges that the Company is offering and selling the Shares in reliance upon an exemption from the registration requirements of the Securities Act and that the Shares are “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act.  Ascentage is not purchasing its portion of the Shares with a view to, or for offer or sale in connection with, any distribution thereof (within the meaning of the Securities Act) that would be in violation of the securities laws of the United States or any state thereof.  Ascentage became aware of the offering of Shares by the Company solely by direct contact between itself and the Company or between itself and one or more agents acting on behalf of the Company, with whom it had a pre-existing business relationship.  Ascentage did not become aware of the offering or the Shares by any other means, including by any form of general advertising or general solicitation.

6. Ascentage recognizes the economic risk.  Ascentage realizes that the acquisition of the Shares involves a high degree of risk, and that the Company’s future prospects are uncertain.  Ascentage is able to hold the Shares indefinitely if required, and is able to bear the loss of the entire investment in the Shares.

7. Ascentage recognizes this is not a general solicitation.  Ascentage understands that the acquisition of the Shares was not the result of any “general solicitation or general advertising” within the meaning contemplated by Rule 502(c) of Regulation D of the Securities Act.

US-DOCS\106256636.1

8. Ascentage knows that the Shares are restricted securities.  Ascentage understand that the Shares are “restricted securities” in that the Company’s sale of the Shares has not been registered under the Securities Act in reliance upon an exemption for non-public offerings.  In this regard, Ascentage also understands and agrees that:

A. Ascentage must hold the Shares indefinitely, unless any subsequent proposed resale is registered under the Securities Act, or unless an exemption from registration is otherwise available (such as Rule 144);

B. the Company is under no obligation to register any subsequent proposed resale of

C. the Shares; and the certificate evidencing the Shares will be imprinted with a legend which prohibits the transfer of the Shares unless such transfer is registered or such registration is not required in the opinion of counsel for the Company.

9. Ascentage is familiar with Rule 144.  Ascentage is familiar with Rule 144 adopted under the Securities Act, which in some circumstances permits limited public resales of “restricted securities” like the shares acquired from an issuer in a non-public offering.  Ascentage understands that its ability to sell the Shares under Rule 144 in the future is uncertain, and may depend upon, among other things: (i) the availability of certain current public information about the Company; (ii) the resale occurring more than a specified period after its acquisition and full payment (within the meaning of Rule 144) for the Shares; and (iii) if Ascentage is an affiliate of the Company (A) the sale being made in an unsolicited “broker’s transaction”, transactions directly with a market maker or riskless principal transactions, as those terms are defined under the Securities Exchange Act of 1934, as amended, (B) the amount of shares being sold during any three-month period not exceeding the specified limitations stated in Rule 144, and (C) timely filing of a notice of proposed sale on Form 144, if applicable.

10. Ascentage knows that Rule 144 may never be available.  Ascentage understands that the requirements of Rule 144 may not be met, and that the Shares may not be saleable under Rule 144, other than through the Company’s failure to comply with the requirements of Rule 144.  Ascentage further understands that at the time Ascentage wish to sell the Shares, there may be no public market for the Company’s stock upon which to make such a sale, or the current public information requirements of Rule 144 may not be satisfied other than through the Company’s failure to satisfy such requirements, either of which may preclude it from selling the Shares under Rule 144 even if the relevant holding period had been satisfied.

11. Ascentage knows that Ascentage is subject to further restrictions on resale.  Ascentage understands that in the event Rule 144 is not available to it, absent an effective registration under the Securities Act, the Shares may only be offered, sold or otherwise transferred (x) to the Company, (y) outside the United States in accordance with Rule 904 of Regulation S or (z) pursuant to an exemption from registration under the Securities Act,(which may or may not be available), or each of the following: (i) its written notice to the Company containing detailed information regarding the proposed sale, (ii) its providing an opinion of its counsel to the effect that such sale will not require registration, and (iii) the Company notifying Ascentage in writing that its counsel concurs in such opinion.  Ascentage understands that although Rule 144 is not

US-DOCS\106256636.1
