(c) In its sole discretion, Unity may elect in lieu of the payment of the milestone payments owing to Ascentage under this Section 6.2, to grant to Ascentage that number of shares of Unity common stock of equivalent value (based on the Fair Market Value of such Unity common stock at the time of such grant).

6.3 Royalties. In partial consideration of the licenses granted herein to Unity, Unity shall pay to Ascentage a running royalty equal to the percentage set forth below on the Net Sales of Licensed Product, subject to any adjustments set forth in Sections 6.5 and 6.6, and in accordance with the payment provisions of Article 7 below.

6.4 Royalty Term. Unity’s obligation to pay royalties on Net Sales of Licensed Product under this Agreement shall continue on a country-by-country and Licensed Product-by-Licensed Product basis until the later of (a) abandonment or expiration of the last Valid Claim that claims the [***] of the Compound contained in such Licensed Product in such country, (b) the date of expiry of any applicable regulatory, pediatric, orphan drug or data exclusivity obtained for such Licensed Product in such country, or (c) ten (10) years after the first commercial sale of the Licensed Product by or under the authority of Unity in any country in the Territory.

6.5 Royalty Stacking. Unity shall be entitled to deduct from the amounts owing to Ascentage under Sections 6.2 and 6.3 above [***] percent ([***]%) of any royalties or other payments made to Third Parties for Enabling IP, provided that (a) the total aggregate amount payable to Ascentage under Sections 6.2 and 6.3 in any [***] may not be reduced to less than [***] percent ([***]%) of the amounts that would otherwise be due Ascentage in such [***], and (b) Unity shall not be entitled to deduct any royalties or other payments made under the Existing Agreements.

consecutive [***] a market share in such country of at least [***] percent ([***]%) of the then combined unit volume of the corresponding Licensed Product (i.e., the Licensed Product containing the same active pharmaceutical ingredient(s) as are present in the Generic Product) and such Generic Product, then Unity’s obligation to pay royalties to Ascentage on Net Sales of such Licensed Product in such country shall be reduced to [***] percent ([***]%) of the amounts that would otherwise be due Ascentage under Section 6.3 in such [***].

6.7 Maximum Reduction to Royalties. Notwithstanding anything to the contrary in this Article 6, in no event shall the royalties owing to Ascentage with respect to Net Sales of a Licensed Product in any country be reduced by cumulative operation of Sections 6.5 and 6.6 to less than [***] percent ([***]%) of the amounts that would otherwise be due Ascentage under Section 6.3 in such [***].

6.8 Combination Products. In the event that a Licensed Product is sold for a single price in combination with another therapeutically active pharmaceutical ingredient, or other product or service, for which no royalty would be due hereunder if sold separately, Net Sales from such combination sales, for purposes of calculating the applicable royalty rate and the applicable royalty due under Section 6.3 shall be calculated by multiplying the Net Sales of the combination product by the fraction A/(A + B), where A is the average gross selling price during the previous [***] of the Licensed Product sold separately and B is the gross selling price during the previous [***] of the therapeutically active ingredient, product or service. In the event that separate sales of the Licensed Product or the additional therapeutically active ingredient, product or service were not made during the previous [***], then the Net Sales shall be reasonably allocated between such Licensed Product and such other active ingredient, product or service as agreed upon by the Parties, or failing agreement, determined in accordance with Section 14.1 (Dispute Resolution) below.

The shares of common stock issued to Ascentage shall be duly adjusted for any bonus issue, share split, consolidation, subdivision, reclassification, recapitalization or similar arrangement of Unity, in each case in accordance with, and as expressly contemplated by, Unity’s certificate of incorporation, as may be amended from time to time in good faith.

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.

Waiver.  Either party’s failure to enforce any provision of this Agreement shall not in any way be construed as a waiver of any such provision, nor prevent that party from thereafter enforcing any other provision of this Agreement.  The rights granted both parties hereunder are cumulative and shall not constitute a waiver of either party’s right to assert any other legal remedy available to it.

G. Licensor Investment Representations and Further Documents.  The Licensor agrees upon request to execute any further documents or instruments necessary or reasonably desirable in the view of the Company to carry out the purposes or intent of this Agreement, including (but not limited to) the applicable exhibits and attachments to this Agreement.

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.
