(d) In establishing the royalty structure of this Section 6.3, the Parties recognize, and Licensee acknowledges, the substantial value of the various actions and investments undertaken by SGI prior to the Effective Date. Such value is significant and in addition to the value of SGI’s grant to Licensee of the Exclusive License pursuant to Section 3.1, as it enables the rapid and effective development and commercialization of the Licensed Products in the Territory. Therefore, the Parties agree that the royalty payments calculated as a percentage of [***] (plus the fees and milestone payments provided for elsewhere herein) provide fair compensation to SGI for these additional benefits.

ARTICLE 9 - INVENTIONS AND PATENTS

9.1 Ownership of Inventions.

9.1.1 Disclosure of Inventions. Each Party shall promptly disclose to the other Party, including without limitation at the joint meetings provided in Section 5.2, the making, conception or reduction to practice of any inventions directly arising out of activities conducted under this Agreement (“Program Inventions”).

9.1.2 Ownership of Program Inventions. All right, title and interest in all Program Inventions that are discovered, made or conceived as part of the activities conducted under this Agreement shall be owned as follows:

(a) [***] shall own all Program Inventions that (i) are invented solely by one or more employees, agents or consultants of [***] and do not primarily relate to the [***] or (ii) are invented solely or jointly by employees, agents or consultants of [***] and/or [***] and primarily relate to the [***]. To the extent that any such Program Inventions relating primarily to the [***] shall have been invented by [***] and are owned by [***], [***] hereby assigns all of its right, title and interest therein to [***];

(b) [***] shall own all Program Inventions that (i) are invented solely by one or more employees, agents or consultants of [***] and do not primarily relate to the [***] or (ii) are invented solely or jointly by employees, agents or consultants of [***] and/or [***] and primarily relate to the [***]. To the extent that any Program Inventions relating primarily to Drug Conjugation Technology shall have been invented by [***] and are owned by [***], Licensee hereby assigns all of its right, title and interest therein to [***]; and

(c) Except as set forth in Sections 9.1.2(a) and 9.1.2(b), Licensee and SGI shall jointly own all other Program Inventions. For purposes of clarification and notwithstanding anything to the contrary set forth herein, all Program Inventions that relate primarily to ADCs, including without limitation, patents or patent applications claiming compositions of matter or methods of use of Licensed Products, shall be jointly owned.

(d) Inventorship, for purposes of this Agreement, shall be determined in accordance with applicable national patent laws. To the extent permissible under applicable national patent laws, each Party will cause each employee and contractor conducting work on such Party’s behalf under this Agreement to be subject to a contract that (a) compels prompt disclosure to the Party of all inventions and other intellectual property conceived, created or reduced to practice by such employee or contractor during his or her performance under the Research Program and (b) assigns to such Party all right, title and interest in and to all such inventions and other intellectual property and all related Patents. Each Party will require each employee and contractor conducting work on such Party’s behalf under this Agreement to maintain records in sufficient detail and in a good scientific manner appropriate for patent purposes to properly reflect all work done. To the extent any royalties are owed to an employee or contractor of a Party relating to an invention, that Party shall be solely responsible for such royalties.

9.2 Patent Prosecution and Maintenance.

-19-

9.2.1 SGI shall be responsible for and shall control the preparation, filing, prosecution, grant and maintenance of all SGI Patents. Throughout the Term of this Agreement, SGI shall, at its sole expense, prepare, file, prosecute and maintain such SGI Patents in good faith consistent with its customary patent policy and its reasonable business judgment, and shall consider in good faith the interests of Licensee in so doing.

9.2.2 Each Party shall be responsible for and shall control the preparation, filing, prosecution, grant and maintenance, of any patents and patent applications claiming Program Inventions owned solely by it in accordance with [***] and shall, at its [***] in good faith consistent with [***]. Patents and patent applications claiming Program Inventions [***] by both Parties in accordance with Section 9.1 (“Joint Patents”) shall be [***]. The costs for all other Joint Patents shall be [***]; provided, that the [***].

9.2.3 If either Party decides not to continue prosecuting any Joint Patents or not to maintain any Joint Patent claiming a Program Invention then such Party shall promptly so notify the other Party (which notice shall be at least [***] before any relevant deadline for such patent). Thereafter, the other Party shall have the right to prosecute or maintain such patent, at such Party’s [***].

9.2.4 The Parties shall at all times fully cooperate with each other in order to reasonably implement the foregoing provisions of this Section 9.2. Such cooperation may include each Party’s execution of necessary legal documents, coordinating filing and/or prosecution of applications for Joint Patents to avoid potential conflicts with SGI Patents during prosecution (including novelty, enablement, estoppel and double patenting, execution of amendments and documents for reliance on the CREATE Act, if mutually agreed upon by both parties), and the assistance of each Party’s relevant personnel. Without limiting the foregoing, it is understood that even if a Party is permitted to reference the other Party’s technology in a patent application pursuant to this Agreement, the filing Party shall not file any such patent application without first confirming with the non-filing Party in writing that any such filing could not reasonably be expected to adversely affect the non-filing Party’s patent strategy. If the non-filing Party determines that any such filing could adversely affect its filing strategy, the filing Party shall not file any such patent application and the Parties shall cooperate in accordance with this Section 9.2.4 to determine a strategy that would protect each Party’s interests, including, without limitation, delaying the filing or co-owning such patent application, as the case may be. Except as otherwise expressed authorized in this Agreement, Licensee shall not disclose and/or claim in any patent application, patent or publication any Confidential Information within the SGI Technology, Drug Conjugation Technology or Drug Conjugation Materials without SGI’s prior written consent. Except as otherwise expressly authorized in this Agreement, SGI shall not disclose and/or claim in any patent application, patent or publication any Confidential Information within the Licensee technology without Licensee’s prior written consent.

9.3 Enforcement of SGI Patents.

9.3.1 SGI shall have the first right, at its sole expense, but not the obligation, to determine the appropriate course of action to enforce the SGI Patents or otherwise abate the infringement thereof, to take (or refrain from taking) appropriate action to enforce the SGI Patents, to control any litigation or other enforcement action and to enter into, or permit, the

-20-

settlement of any such litigation or other enforcement action with respect to the SGI Patents. SGI shall in good faith consider the interests of Licensee in conducting the foregoing activities. All monies recovered upon the final judgment or settlement of any such suit to enforce any SGI Patents with respect to the manufacture, use or sale by Third Parties of products competitive with Licensed Products or technologies competitive with Drug Conjugation Technology shall be [***]. Licensee shall reasonably cooperate with SGI in any such action at SGI’s expense, to enforce the SGI Patents, including being joined as a party to such action if necessary. In no event may SGI assert an argument or settle a suit in a manner that would materially prejudice the rights granted to Licensee under this Agreement without Licensee’s prior written consent.

9.3.2 If SGI fails to take any action to enforce the SGI Patents or control any litigation with respect to the SGI Patents with respect to the manufacture, use or sale by Third Parties of products competitive with Licensed Products or technologies competitive with Drug Conjugation Technology within a period of [***] after the Parties receive reasonable notice of the infringement of the SGI Patents, or in the case of an ANDA filing, within [***] of receipt of the notice of submission of the ANDA filing, then Licensee shall have the right to bring and control any such action by counsel of its own choice, at its [***]. In such case, all monies recovered upon the final judgment or settlement of any such suit to enforce any SGI Patents shall be [***]. In such a case, SGI shall cooperate fully with Licensee, at [***], in its efforts to enforce the SGI Patents, including being joined as a party to such action if necessary. In no event may Licensee assert an argument or settle a suit in a manner which would render a claim in the SGI Patents invalid or unenforceable without SGI’s prior written consent.

9.3.3 Licensee shall have the right, at its [***], to determine the appropriate course of action to enforce patents claiming Program Inventions owned [***] by [***] in accordance with [***], or otherwise to abate the infringement thereof, to take (or refrain from taking) appropriate action to enforce the Program Licensee Patents, to control any litigation or other enforcement action and to enter into, or permit, the settlement of any such litigation or other enforcement action with respect to the Program Licensee Patents. All monies recovered upon the final judgment or settlement of any such suit to enforce any Program Licensee Patents shall be retained by [***]. SGI shall fully cooperate with Licensee, at [***], in any action to enforce the Program Licensee Patents.

9.3.4 In the event either Party becomes aware of an infringement by a Third Party of a Joint Patent, it shall promptly notify the other Party which shall be followed by a written notice. Subject to the rights of both Parties set forth in Sections 9.3.1 and 9.3.2 above, Licensee shall have the right to bring and control any such action related to a Joint Patent related to a Licensed Product, by counsel of its own choice at its sole expense. For all other Joint Patents, the Parties shall cooperate in selecting an outside legal firm mutually agreeable to both Parties and shall equally share control of the suit and all expenses. In such case, all monies recovered upon the final judgment or settlement of any such suit to enforce any Joint Patents shall be allocated first to any Third Party from which either Party obtained license with respect to such Joint Patents, to the extent required under the relevant in-license to either Party, second to the Parties to the extent necessary to compensate each for its respective expenses in its enforcement, and finally any remaining amounts shall be treated as Net Sales subject to the royalty obligations described in Article 6 of this Agreement if the suit is solely related to a Licensed Product and otherwise, shall be prorated between the Parties in accordance with the

-21-

damages for which such judgment or settlement is reasonably intended to compensate. If the monies recovered are not sufficient to compensate for all expenses of both Parties, such monies shall be divided on a pro rata basis based on the proportion of each Parties expenses to the total combined expenses of enforcement. If either Party chooses not to participate in the enforcement action to the extent it is required, it shall forfeit its right to share in the recovery, but shall nonetheless cooperate fully with the other Party, at the other Party’s expense, in its efforts to enforce the Joint Patents, including being joined as a party to such action if necessary. In no event shall a Party make an argument or settle a dispute which would render a claim in a Joint Patent to be invalid or unenforceable without the other Party’s prior written consent.

9.4 Prior Patent Rights. Notwithstanding anything to the contrary in this Agreement, with respect to any SGI Patents that are subject to the SGI In-Licenses, the rights and obligations of the Parties under Section 9.2 and 9.3 shall be subject to the rights of the licensor of the SGI In-License to participate in and control prosecution, maintenance and enforcement of such SGI Patents, and to receive a share of damages recovered in such action, in accordance with the terms and conditions of the applicable SGI In-License.

ARTICLE 10 - INFRINGEMENT ACTIONS BROUGHT BY THIRD PARTIES

If Licensee, SGI or any of their respective Affiliates, or any of Licensee’s Sublicensees, is sued by a Third Party for infringement of a Third Party’s patent because of the use of the Drug Conjugation Technology in connection with activities conducted pursuant to this Agreement, the Party that has been sued shall promptly notify the other Party within [***] of its receipt of notice of such suit. The notice shall set forth the facts of such infringement available to the relevant Party. The Parties shall then meet to discuss each Party’s commercial interests in the defense of the suit, a plan for the defense of the suit, how the costs of the suit should be allocated, and which Party should have primary control of the suit, provided that if such infringement relates primarily to Drug Conjugation Technology, then SGI shall have the first right to control such suit. In no event may one Party settle or otherwise consent to an adverse judgment in such suit that materially diminishes the rights or interests of the other Party without the express written consent of the other Party.

ARTICLE 11 - REGULATORY ASSISTANCE

Should Licensee desire to file an IND or an application for Regulatory Approval, or equivalents of the foregoing, for a Licensed Product, SGI will use reasonable commercial efforts to provide at Licensee’s request, technical information SGI has created or possesses that is reasonably required by Licensee, including information relating to the [***], as well as documents related specifically to Drug Conjugation Technology that are necessary to compile the Chemistry Manufacturing and Controls section of an application for Regulatory Approval and any other relevant information SGI has created or possesses as the Parties may mutually agree. If SGI has a drug master file with the FDA or equivalent that contains information useful to support an IND or application for Regulatory Approval, [***]. In the event SGI agrees to provide regulatory assistance beyond the limited activities described above, the Parties shall [***].

13.6.1 Except where explicitly provided within this Agreement or by operation of any applicable law, termination of this Agreement for any reason, or expiration of this Agreement, will not affect any: (a) obligations, including payment of any royalties or other sums which have accrued as of the date of termination or expiration, and (b) rights and obligations which are intended to survive termination or expiration of this Agreement, including provisions of Articles 1, 8, 9, 10, 14 (as to actions arising during the term of this Agreement or in the course of a Party practicing any licenses retained by such Party thereafter), 18 and 19, Sections 7.2, 7.3 and 13.6 and any payment obligations pursuant to Section 6 incurred prior to termination. Notwithstanding the foregoing, all licenses granted by SGI to Licensee hereunder, including all Exclusive Licenses, and all sublicenses granted by Licensee hereunder, will immediately terminate upon termination of this Agreement pursuant to Sections 13.2, 13.3 (if SGI is terminating party) 13.4 (if SGI is terminating party) or 13.5.

13.6.2 License to Licensee.

-24-

free. If such license is granted upon termination by Licensee under Sections 13.3 or 13.4 and Licensee so desires to obtain such license, then SGI shall grant such license to Licensee with terms and conditions to be mutually agreed upon by both Parties. Under all circumstances, any royalties owed to a Third Party pursuant to an SGI In-License shall not be affected by this Section 13.6.2 and shall be paid by Licensee under Section 6.4 of this Agreement.

13.6.3 License to SGI. Upon any termination of the Exclusive License or termination by SGI under Section 13.3 or Section 13.4, Licensee shall grant a license to SGI in the Territory under the Licensee ADC Know-How described in Section 1.1.42 and Licensee ADC Patents described in Section 1.1.43 to identify, develop and commercialize products that contain an ADC upon the terms and conditions to be mutually agreed upon by both Parties.

14.1 Direct Indemnity.

14.1.1 Each Party shall defend, indemnify and hold harmless the other Party from and against all liabilities, losses, damages, and expenses, including reasonable attorneys’ fees and costs, (collectively, the “Liabilities”) resulting from all Third Party claims, suits, actions, terminations or demands (collectively, the “Claims”) that are incurred, relate to or arise out of (a) the breach of any material provision of this Agreement by the indemnifying Party (or the inaccuracy of any representation or warranty made by such Party in this Agreement), or (b) the gross negligence, recklessness or willful misconduct of the indemnifying Party in connection with the performance of its obligations hereunder.

14.1.2 Licensee shall defend, indemnify and hold harmless SGI from and against all Liabilities resulting from all Claims that are incurred, relate to or arise out of the development, manufacture or commercialization of Licensed Products by SGI for Licensee or by Licensee, its Affiliates or Sublicensees, including any failure to test for or provide adequate warnings of adverse side effects, or any manufacturing defect in any Licensed Product; except in each case to the extent such Liabilities resulted from the negligence, recklessness or willful misconduct by SGI or the inaccuracy of any representation or warranty made by SGI in this Agreement or from any other action for which SGI must indemnify Licensee under Section 14.1.3.

14.1.3 SGI shall defend, indemnify and hold harmless Licensee from and against all Liabilities resulting from all Claims that are incurred, relate to or arise out of any claims of infringement of Third Party rights arising out of the use of SGI Technology to make ADCs or Licensed Products (but not any other technology, including the composition or methods of making or using Antibodies or technology not relating to Drug Conjugation Technology), except to the extent such Liabilities resulted from the negligence, recklessness or willful misconduct by Licensee or the inaccuracy of any representation or warranty made by Licensee in this Agreement or any other action for which Licensee must indemnify SGI hereunder.

-25-

14.2 Procedure. A Party (the “Indemnitee”) that intends to claim indemnification under this Article 14 shall promptly provide notice to the other Party (the “Indemnitor”) of any Liability or action in respect of which the Indemnitee intends to claim such indemnification, which notice shall include a reasonable identification of the alleged facts giving rise to such Liability, and the Indemnitor shall have the right to participate in, and, to the extent the Indemnitor so desires, jointly with any other Indemnitor similarly noticed, to assume the defense thereof, including the defense of Indemnitee, with counsel selected by the Indemnitor at its own cost. However, notwithstanding the foregoing, the Indemnitee shall have the right to retain its own counsel, with the fees and expenses to be paid by the Indemnitee. Regardless of whether Indemnitor exercises its right to select its counsel and to defend Indemnitee directly or the Parties proceed with separate counsel, the Parties shall exercise reasonable efforts to cause their respective counsel to enter into a joint defense agreement providing for the protection of confidential communication among SGI, Licensee and their respective counsel and to otherwise cooperate in all aspects of the defense of such Claim if such agreement is appropriate. Any settlement of a Liability for which any Indemnitee seeks to be indemnified, defended or held harmless under this Article 14 that could adversely affect the Indemnitee shall be subject to prior consent of such Indemnitee, provided that such consent shall not be withheld unreasonably.

ARTICLE 15 - FORCE MAJEURE

No Party (or any of its Affiliates) shall be held liable or responsible to the other Party (or any of its Affiliates), or be deemed to have defaulted under or breached the Agreement, for failure or delay by such Party in fulfilling or performing any term of the Agreement when such failure or delay is caused by or results from causes beyond the reasonable control of the affected Party (or any of its Affiliates), including fire, floods, embargoes, war, acts of war (whether war be declared or not), insurrections, riots, civil commotions, acts of God, earthquakes, or omissions or delays in acting by any governmental authority (collectively, “Events of Force Majeure”); provided, however, that the affected Party shall exert all reasonable efforts to eliminate, cure or overcome any such Event of Force Majeure and to resume performance of its obligations promptly. Notwithstanding the foregoing, to the extent that an Event of Force Majeure continues for a period in excess of [***], the affected Party shall promptly notify in writing the other Party of such Event of Force Majeure and within [***] of the other Party’s receipt of such notice, the Parties shall negotiate in good faith either (a) a resolution of the Event of Force Majeure, if possible, (b) an extension by mutual agreement of the time period to resolve, eliminate, cure or overcome such Event of Force Majeure, (c) an amendment of this Agreement to the extent reasonably possible, or (d) an early termination of this Agreement.

ARTICLE 16 - ASSIGNMENT

This Agreement may not be assigned or otherwise transferred, nor, except as expressly provided hereunder, may any right or obligations hereunder be assigned or transferred to any Third Party by either Party without the consent of the other Party, such consent not to be unreasonably withheld; provided, however, that either Party may, without such consent but with notification, assign this Agreement and its rights and obligations hereunder to any of its Affiliates or in connection with the transfer or sale of all or substantially all of its business, or in the event of its merger or consolidation of such Party (such merger or consolidation shall be hereinafter referred to as a “Change in Control”). Any permitted assignee shall assume all rights

-26-

and obligations of its assignor under this Agreement; provided, however, that [***]. Any attempted assignment of this Agreement not in accordance with this Article 16 shall be void and of no effect. Any attempted assignment of this Agreement not in accordance with this Article 16 shall be void and of no effect.

ARTICLE 17 - SEVERABILITY

Each Party hereby agrees that it does not intend to violate any public policy, statutory or common laws, rules, regulations, treaty or decision of any government agency or executive body thereof of any country or community or association of countries. Should one or more provisions of this Agreement be or become invalid, the Parties hereto shall substitute, by mutual consent, valid provisions for such invalid provisions, in their economic effect, are sufficiently similar to the invalid provisions that it can be reasonably assumed that the Parties would have entered into this Agreement based on such valid provisions. In case such alternative provisions cannot be agreed upon, the invalidity of one or several provisions of this Agreement shall not affect the validity of this Agreement as a whole, unless the invalid provisions are of such essential importance to this Agreement that it is to be reasonably assumed that the Parties would not have entered into this Agreement without the invalid provisions.

ARTICLE 18 – INSURANCE

During the Term and thereafter for the period of [***], each Party shall maintain on an ongoing basis comprehensive general liability insurance covering its obligations and activities hereunder with reputable and financially secure insurance carriers in a form and at levels as customary for a company of this size in the pharmaceutical or biotechnology industry, as applicable, in the Territory (or reasonable self-insurance sufficient to provide materially the same level and type of protection as required pursuant to Section 11.5 of the BMS Agreement). In addition, Licensee agrees to provide the information regarding its self-insurance plan as set forth in Section 4.2(b) of the BMS Agreement and otherwise comply with the requirements set forth therein regarding self-insurance plans.
