Joint Research Committee. The Parties hereby establish a committee to facilitate the Research Program as follows:

Composition; Decision Making.

The Committee shall be comprised of [***] senior representatives of Merck (who shall be employees of Merck or its Affiliate, as applicable) and [***] senior representatives of Company. Each Party may change its representatives to the Committee from time to time in its sole discretion, effective upon notice to the other Party of such change. These representatives shall have appropriate technical credentials, experience and knowledge, and ongoing familiarity with the Research Program. Additional representative(s) or consultant(s) may from time to time, by mutual consent of the Parties, be invited to attend Committee meetings, subject to such representative’s or consultant’s written agreement to comply with the requirements of Section 5.1.

The goal of all decision-making of the Committee shall be to achieve consensus, and the Committee shall act by unanimous consent. The representatives from each Party will have collectively [***] on behalf of such Party. In the event that the Committee cannot or does not, after reasonable, good faith efforts, reach agreement on an issue within the Committee’s scope as set forth in Section 2.3.2 within [***] after such issue was first referred to the Committee, such issue shall be escalated to Merck’s [***] and Merck’s [***], for all other issues and the Chief Executive Officer of the Company or his/her designee (collectively, the “Executives”). In the event the Executives are unable to resolve a given issue within [***] after the dispute is first referred to the Executives, then the resolution or course of conduct shall be determined by Merck, in its reasonable discretion subject in all cases to Section 2.3.2(c) (but, for clarity, such matter shall not be subject to the dispute resolution mechanisms set forth in Section 11.7).

Scope of Committee Oversight.

The Committee shall be responsible for overseeing the Research Program, including, without limitation, to (i) review and amend the Research Plan from time to time, including to amend the Research Plan to require additional FTEs or reduce the number of FTEs, (ii) review and coordinate the Parties’ activities under the Research Program, (iii) confer regarding the status of the Research Program and the progress under the Research Program and to make determinations and decisions in connection with the activities under the Research Program (including issues of priority), (iv) review relevant data generated under the Research Program, (v) consider and advise on any technical issues that arise under the Research Program, (vi) review and amend the Initial Research Budget as necessary and propose and agree upon additional Research Budgets in accordance with Section 6.2.1, and (vii) determine such other matters as allocated to the Committee hereunder (including the formation or disbandment of subcommittees), subject in each case (i)-(vii) to Section 2.3.2(c).

The Committee is empowered to establish, from time to time, one or more subcommittees to oversee particular activities under the Research Program, and such subcommittees will be constituted as the Committee agrees. The subcommittees shall oversee activities within areas delegated to them by the Committee and to make decisions regarding matters within each of their purviews.

Collaboration Targets and Right to Exclusive License.

Subject to Section 3.2, Merck shall have the right to designate two Targets to be the subject of the exclusive licenses set forth in Section 4.1 (each, a “Collaboration Target”). For clarity, each of the initial two Collaboration Targets may be subject to Substitution in accordance with Section 3.4, and any Substitution rights described in this Agreement shall in all cases be subject to and in accordance with the procedures set forth in Section 3.2. The Parties acknowledge that Merck has designated the first Collaboration Target herein, which is set forth on Schedule 3.1.1 (“First Collaboration Target”).

From the Effective Date of the Agreement to the date that is [***] from such date (such period, the “Target Selection Period”), Merck shall have the right to designate a second Collaboration Target (“Second Collaboration Target”) in accordance with the procedures set forth in Section 3.2, provided that in no event shall any Target identified on Schedule 3.1.2 hereto or identified as unavailable by the Gatekeeper pursuant to Section 3.2.3 (each, an “Unavailable Target”) be a Collaboration Target.

Target Gatekeeping and Availability.

Within [***] of the Effective Date of the Agreement, Company shall, at its expense, appoint an outside counsel, reasonably acceptable to Merck, to function as a neutral gatekeeper (“Gatekeeper”) and determine the availability of any Nominated Targets during the Target Selection Period and the Target Substitution Period pursuant to this Section 3.2. Any actual expenses incurred by Company in the gatekeeping process shall be reimbursed by Merck pursuant to Section 6.2.2, subject to the limitations set forth therein. Company shall ensure that the Gatekeeper is responsible for carrying out the procedures set forth in this Section 3.2.

During the Target Selection Period or the Target Substitution Period, as applicable, Merck may elect to undergo the gatekeeping process with a proposed Target by submitting such Target (“Nominated Target”) in writing to the Gatekeeper for the purpose of determining whether Company is able to grant the exclusive licenses under Section 4.1 of this Agreement with respect to such Target (such Target, an “Available Target”) and identifying in such request if (i) Merck intends to designate such Nominated Target as the Second Collaboration Target, (ii) Merck intends to designate such Nominated Target as a potential Collaboration Target and reserve such Target pursuant to Section 3.3, or (iii) Merck intends to replace a Collaboration Target with the Nominated Target pursuant to Section 3.4 (each of (i) – (iii), a “Target Request”) if such Target is an Available Target. The Gatekeeper shall review such request and, if the Target Request was made pursuant to the foregoing clause (i), shall inform both Parties in writing if the Nominated Target is an Available Target and in such case, such Nominated Target shall automatically become the Second Collaboration Target as of the date that Merck receives such written notice (“Second Collaboration Target Effective Date”). If the Nominated Target is an Unavailable Target pursuant to Section 3.2.3, the Gatekeeper shall inform Merck in writing and Merck shall have the right to undergo the gatekeeping process with a different Target up to the end of the Target Selection Period or the Target Substitution Period, as applicable. The identity of any and all Nominated Targets shall be the confidential information of Merck and unless and until the Nominated Target becomes a Collaboration Target pursuant to this Section 3.2.2 or pursuant to any of Sections 3.3.3, 3.3.4, or 3.4.1, the Gatekeeper shall not disclose the identity of any Nominated Target to any person at Company or to any Third Party.

Target Availability. During the Target Selection Period and Target Substitution Period, the Gatekeeper shall promptly inform Company following receipt of a Target Request that such a request was made, but shall not disclose the identity of the Nominated Target to Company. Company shall have [***] following such notice from the Gatekeeper to provide an updated list of Unavailable Targets to the Gatekeeper, which list shall provide the basis of such unavailability for each Unavailable Target and shall further provide reasonable supporting documentation regarding the basis of such unavailability. Subject to Section 3.3.4, the Gatekeeper, in determining whether a Nominated Target is an Available Target, shall only reject a Target Request and designate a Nominated Target as an Unavailable Target if, at the time of such request, the Nominated Target is listed on Schedule 3.1.2 or the list of Unavailable Targets provided by Company indicates that Company is:

contractually obligated to grant, or has granted, to a Third Party, rights with respect to products containing TRACTr Compounds directed to such Target;

actively and in good faith engaged in bona fide negotiations with a Third Party regarding the development or commercialization of products containing TRACTr Compounds directed to such Target; or

actively performing or has performed activities on its own behalf regarding the development or commercialization of TRACTr Compounds directed to such Target or products incorporating such TRACTr Compounds whereby [***].

Limited Right of Merck to Reserve Potential Targets.

During the Target Selection Period, Merck shall have the right to designate up to two (2) Targets as potential Collaboration Targets, which, if available pursuant to the gatekeeping process set forth in Section 3.2, shall be reserved for Merck (each, a “Reserved Target”), subject to Section 3.3.4. In order to nominate a Target as a potential Collaboration Target, Merck shall submit a Target Request to the Gatekeeper, indicating that Merck intends to designate such Nominated Target as a potential Collaboration Target if such Target is an Available Target as contemplated in Section 3.2.2(ii). The Gatekeeper shall review such Target Request and shall notify Merck in writing if such Target is an Available Target pursuant to Section 3.2, and in such case, such Nominated Target shall automatically become a Reserved Target from the date that Merck receives such written notice until the earlier of: (i) the date that such Target becomes the Second Collaboration Target pursuant to Section 3.3.3, or (ii) the end of the Target Selection Period (“Target Reservation Period”). If the Nominated Target is an Unavailable Target pursuant to Section 3.2.3, the

Merck may replace a designated Reserved Target with another Target no more frequently than once every [***] during the Target Reservation Period applicable to such Reserved Target, provided that at no time may more than two (2) Targets be designated Reserved Targets. In order to nominate a Target to replace a Reserved Target as contemplated in Section 3.2.2(iii), Merck shall submit a Target Request to the Gatekeeper in writing specifying (i) the proposed Target that it wishes to reserve pursuant to this Section 3.3.2, and (ii) the Reserved Target that it wishes to replace. The Gatekeeper shall review such request in accordance with the procedures set forth in Section 3.2, and shall inform Merck in writing if such Target is an Available Target and, in such case, such Target will become a Reserved Target as of the date that Merck receives such notice and the replaced Target shall automatically cease to be a Reserved Target as of such date. If the Gatekeeper informs Merck that the Target is an Unavailable Target, then Merck shall have [***] to propose an alternative Target to replace the designated Reserved Target by submitting such proposal in writing to the Gatekeeper, who shall determine the availability of the alternative Target pursuant to Section 3.2.

At any time during the Target Reservation Period for a particular Reserved Target, Merck shall have the right to request that such Reserved Target become the Second Collaboration Target by submitting notice to the Gatekeeper in writing providing the identity of the Reserved Target and specifically requesting that such Reserved Target become the Second Collaboration Target. In the event Merck provides such notice, the Gatekeeper shall inform Company in writing within [***] of the identity of the Second Collaboration Target and the date that the Company receives such notice shall be the Second Collaboration Target Effective Date. After the Target Reservation Period, if Merck has not elected to request that a particular Reserved Target become the Second Collaboration Target, then such Reserved Target shall automatically cease to be a Reserved Target and Company shall have no further obligations to Merck in respect of such Target.

During the Target Selection Period, if Company proposes to initiate any internal research program or engage in any discussions with a Third Party regarding the development or commercialization of TRACTr Compounds or products containing such TRACTr Compounds directed to a Target that is not listed on Schedule 3.1.2 (“Company Proposed Target”), Company shall nominate such Target by providing the name of the Company Proposed Target to the Gatekeeper in writing and indicating its intent to commence research and development activities in respect of such Target. If such Company Proposed Target is a Reserved Target, the Gatekeeper shall notify Merck in writing that the Company has designated a Reserved Target as a Company Proposed Target. Merck shall have [***] from the date of such notification to submit a request to the Gatekeeper in writing that such Reserved Target become the Second Collaboration Target. In such case, the Gatekeeper shall have [***] to so inform Company in writing, the Company Proposed Target shall become the Second Collaboration Target, and the date that Company receives such notice

Substitution of Collaboration Target(s).

For a period of [***] from the Effective Date for the First Collaboration Target and a period of [***] from the Second Collaboration Target Effective Date for the Second Collaboration Target (each, a “Target Substitution Period”), Merck shall have the right, in its sole discretion, to substitute the First Collaboration Target and/or the Second Collaboration Target for another Nominated Target (“Substitution”), provided such Nominated Target is an Available Target at the time of such Substitution. Merck may substitute such Collaboration Target for such other Target by providing a Target Request to the Gatekeeper, which shall specify this Section 3.4.1, and shall further specify: (i) the Collaboration Target that is being substituted (“Replaced Collaboration Target”); and (ii) the Target that Merck wishes to nominate for Substitution. The Gatekeeper shall review such request in accordance with the procedures set forth in Section 3.2 and, if the Nominated Target is an Available Target, shall inform both Parties in writing. In such case, (a) the Replaced Collaboration Target shall automatically be replaced and shall no longer be a Collaboration Target, and shall be deemed a Terminated Collaboration Target subject to Section 9.2.3, and (b) the Nominated Target shall automatically become a Collaboration Target (“Substituted Target”) and shall be subject to the exclusive licenses set forth in Section 4.1. From the end of the Target Substitution Period until the end of the Research Program Term, Merck may substitute a Collaboration Target in accordance with the procedures set forth in this Section 3.4.1 only by mutual written agreement of the Parties. For the avoidance of doubt, Merck’s licenses pursuant to Section 4.1 (including any licenses with respect to any Compound and Licensed Product directed against such Replaced Collaboration Target) and obligations pursuant to Section 4.6, and Company’s obligations pursuant to Section 4.8, in each case with respect to the Replaced Collaboration Target shall cease as of the date the Replaced Collaboration Target is automatically replaced with the Substituted Target.

Merck may make [***] Substitution per Collaboration Target (i.e., there could be [***] Substitution for the First Collaboration Target and [***] Substitution for the Second Collaboration Target) provided that with respect to any Substitution, the proposed Target has undergone the gatekeeping procedure set forth in Section 3.2 and is determined to be an Available Target at the time of such Substitution. For clarity, any Substituted Target shall not be subject to any Milestone Payments under Section 6.3.1 for Milestone Events that were already achieved and paid by the applicable Replaced Collaboration Target. For example, if the Replaced Collaboration Target was the First Collaboration Target at the time of such Substitution, the Substituted Target shall be deemed the First Collaboration Target at the time of Substitution and no additional Milestone Payments shall be due for Milestone Events that were previously achieved and paid for the First Collaboration Target.

If a Target proposed for Substitution under this Section 3.4 is an Unavailable Target, then Merck may, at its sole discretion, propose another Target for Substitution within the Target Substitution Period by submitting a Target Request to the Gatekeeper, or elect to cease development of the applicable Collaboration Target pursuant to Section 9.2.3.

Royalties.

Royalties Payable by Merck. Subject to the terms and conditions of this Agreement, Merck shall pay Company royalties, calculated on a Licensed Product-by-Licensed Product and country-by-country basis, as set forth in this Section 6.4.

Patent Royalties. Subject to the provisions of Section 6.4.1(b), Merck shall pay Company royalties in an amount equal to the following percentage of Net Sales of Licensed Products by Merck or its Related Parties where the sale of such Licensed Product is covered by a Valid Patent Claim in the country of sale:

For Net Sales in each Calendar Year less than [***].

For Net Sales in each Calendar Year for the portion of Net Sales equal to or exceeding [***] and less than [***].

For Net Sales in each Calendar Year for the portion of Net Sales equal to or exceeding [***] and less than [***].

For Net Sales in each Calendar Year for the portion of Net Sales equal to or exceeding [***].

Know-How Royalty. Notwithstanding the provisions of Section 6.4.1(a), on a Licensed Product-by-Licensed Product and country-by-country basis, for countries where the sale of a Licensed Product by Merck or its Related Parties is not covered by a Valid Patent Claim, Merck shall pay royalties on the Net Sales of such Licensed Product in such countries at royalty rates that shall be set at [***] of the applicable royalty rates determined according to Section 6.4.1(a). Such royalties shall be calculated after first calculating royalties under Section 6.4.1(a).

Royalty tiers pursuant to Section 6.4.1(a) and Section 6.4.1(b) shall be calculated based on worldwide Net Sales of each Licensed Product in the Territory, provided that the determination of whether the royalty shall be calculated under Section 6.4.1(a) or Section 6.4.1(b) shall be determined on a country-by-country basis. Royalties on each Licensed Product at the rates set forth above shall continue on a country-by-country basis until the expiration of the latest of: (i) the last-to-expire Valid Patent Claim in such country; (ii) [***]; or (iii) ten (10) years from First Commercial Sale of such Licensed Product in such country.

All royalties are subject to the following conditions:

that only one royalty shall be due with respect to the same unit of Licensed Product;

that no royalties shall be due upon the sale or other transfer among Merck or its Related Parties, but in such cases the royalty shall be due and calculated upon Merck’s or its Related Party’s Net Sales to the first independent Third Party;

no royalties shall accrue on the disposition of Licensed Product by Merck or its Related Parties for use in a Clinical Trial supplied at cost or free of charge; and

no royalties shall accrue on the disposition of Licensed Product in reasonable quantities by Merck or its Related Parties as samples (promotion or otherwise) or as donations (for example, to non-profit institutions or government agencies for a non-commercial purpose) supplied free of charge.

Change in Sales Practices. The Parties acknowledge that during the Term, Merck’s sales practices for the marketing and distribution of Licensed Product may change to the extent to which the calculation of the payment for royalties on Net Sales may become impractical or even impossible. In such event the Parties agree to meet and reasonably discuss in good faith new ways of compensating Company to the extent currently contemplated under Section 6.4.1.

Royalties for Bulk Compound. In those cases in which Merck sells bulk Compound rather than Licensed Product in packaged form to an independent Third Party who is not a sublicensee hereunder, the royalty obligations of this Section 6.4 shall be applicable to the bulk Compound.

Compulsory Licenses. If a compulsory license is granted to a Third Party with respect to a Compound or Licensed Product in any country in the Territory and such compulsory licensee pays to Merck: (a) royalties on the Net Sales of the Licensed Product in such country at a royalty rate lower than the royalty rate provided by Section 6.4.1, then the royalty rate to be paid by Merck on Net Sales in that country under Section 6.4.1 shall be [***]; or (b) [***] for the grant of such sublicense in lieu of paying royalties on the Net Sales of the Licensed Product in such country, then the amount paid to Merck by such compulsory licensee will be [***].

Notwithstanding the foregoing, in no event shall the royalties owed by Merck to Company for such [***] be reduced by more than [***] pursuant to this Section 6.4.5 (provided, however, that if Merck is not able to fully recover the amounts paid by Merck or its Related Parties under any Third Party License as a result of the foregoing restriction, then Merck shall be entitled to carry forward such right of off-set to future Calendar Quarters with respect to such excess amount). At the reasonable request of Merck, Company shall provide assistance to Merck (or its Related Parties) in obtaining any such Third Party Licenses that may be necessary or useful in order to research, develop, make, have made, use, import, offer to sell and/or sell Licensed Product(s) or Compound(s) contained in such Licensed Product(s).

Reports; Payment of Royalty. During the term of this Agreement following the First Commercial Sale of a Licensed Product, Merck shall furnish to Company a [***] report for the [***] showing the Net Sales of all Licensed Products subject to royalty payments sold by Merck and its Related Parties in the Territory during the reporting period and the royalties payable under this Agreement. Reports shall be due on the [***] following the close of each [***]. Royalties shown to have accrued by each royalty report shall be due and payable on the date such royalty report is due. Merck shall keep complete and accurate records in sufficient detail to enable the royalties payable hereunder to be determined.

Upon the written request of Company and not more than [***], Merck shall permit an independent certified public accounting firm of nationally recognized standing selected by Company and reasonably acceptable to Merck, at Company’s expense, to have access during normal business hours to such of the records of Merck as may be reasonably necessary to verify the accuracy of the royalty reports hereunder for any Calendar Year ending not more than [***] prior to the date of such request. The accounting firm shall disclose to Company only whether the royalty reports are correct or incorrect and the specific details concerning any discrepancy. No other information shall be provided to Company without the prior consent of the Merck unless disclosure is required by applicable laws, rules and regulations or by judicial or administrative process.

If such accounting firm correctly identifies a discrepancy made during such period, the appropriate Party shall pay the other Party the amount of the discrepancy within [***] of the date Company delivers to Merck such accounting firm’s written report so correctly concluding, or as otherwise agreed upon by the Parties. The fees charged by such accounting firm shall be paid by [***]; provided, however, that if such audit reveals an underpayment of amounts owed to [***] of the greater of: (i) [***] with respect to the relevant period, or (ii) [***], in which case, Merck will reimburse Company for the reasonable expense incurred by Company in connection with the audit.

Merck shall include in each sublicense granted by it pursuant to this Agreement a provision requiring the sublicensee to make reports to Merck, to keep and maintain records of sales made pursuant to such sublicense and to grant access to such records by Company’s independent accountant to the same extent required of Merck under this Agreement.

Upon the expiration of [***] following the end of any [***], the calculation of royalties payable with respect to such [***] shall be binding and conclusive upon Company, and Merck and its Related Parties shall be released from any liability or accountability with respect to royalties for such [***].

Company shall treat all financial information subject to review under this Section 6.6 or under any sublicense agreement in accordance with the confidentiality and non-use provisions of this Agreement, and shall cause its accounting firm to enter into an acceptable confidentiality agreement with Merck and/or its Related Parties obligating it to retain all such information in confidence pursuant to such confidentiality agreement.

All payments to be made by Merck to Company under this Agreement shall be made in United States dollars and may be paid by check made to the order of Company or bank wire transfer in immediately available funds to such bank account in the United States as may be designated in writing by Company from time to time.

Income Tax Withholding.

Company shall be liable for all income and other taxes (including interest) (“Taxes”) imposed upon any payments made by Merck to Company under this Article 6 (“Agreement Payments”). If applicable laws, rules or regulations require the withholding of Taxes, Merck shall make such withholding payments and shall subtract the amount thereof from the Agreement Payments. Merck shall submit to Company appropriate proof of payment of the withheld Taxes as well as the official receipts within a reasonable period of time. Merck shall provide Company reasonable assistance in order to allow Company to obtain the benefit of any present or future treaty against double taxation which may apply to the Agreement Payments.

Withholding Tax Action. If, at any time during the Term, a Party takes any action of its own discretion (not required by applicable law or a Regulatory Authority), including any assignment, change of place of incorporation, or failure to comply with applicable law or filing or record retention requirements, which results in a withholding or deduction obligation (“Withholding Tax Action”), then such Party shall be responsible for and pay the sum associated with such Withholding Tax Action; provided, however, that such Party will have no obligation to pay any additional amount under this Section 6.8.2 in the event that (i) such increased withholding tax is due, in whole or part, to any action of the other Party, including (A) the assignment by the other Party pursuant to Section 6.8.2 of its rights under this Agreement or any redomiciliation of the other Party or (B) the failure by the other Party to comply with the documentation requirements of applicable law, (ii) such increased withholding tax to the extent that it is otherwise recoverable or creditable by the other Party or its Affiliate, or (iii) such increased withholding tax is due to a change in applicable law following the Party’s assignment under Section 6.8.2.

Termination by Merck Other Than for Cause.

Notwithstanding anything contained herein to the contrary, Merck shall have the right to terminate this Agreement at any time in its sole discretion by giving [***] advance written notice to Company.

Effect of Termination under Section 9.2.1.

No later than [***] after the effective date of such termination, each Party shall return or cause to be returned to the other Party all Information in tangible form received from the other Party and all copies thereof; provided, however, that each Party may retain any Information reasonably necessary for such Party’s continued practice under any license(s) which do not terminate pursuant to this Section, and may keep one (1) copy of Information received from the other Party in its confidential files for record purposes, to demonstrate compliance with its obligations, or assert its rights, under this Agreement, or to comply with applicable law; and further, provided, that a Party shall not be required to erase electronic files created in the ordinary course of business during automatic system back-up procedures pursuant to its electronic record retention and destruction practices that apply to its own general electronic files and information so long as such electronic files are (i) maintained only on centralized storage servers (and not on personal computers or devices), (ii) not accessible by any of its personnel (other than its information technology specialists), and (iii) are not otherwise accessed subsequently except with the written consent of the disclosing Party or as required by law or legal process.

Merck shall not, and shall ensure that its Affiliates, sublicensees and distributors shall not, sell, offer for sale or otherwise commercialize any Compounds or Licensed Products; provided, however, that Merck and its Affiliates, sublicensees and distributors shall be entitled, during the [***] period immediately following the effective date of termination, to [***], subject to and in accordance with the terms of this Agreement (including Article 6 of this Agreement); and

Termination of a Single Collaboration Target. Merck shall have the right to terminate its rights and obligations with respect to a single Collaboration Target (“Terminated Collaboration Target”), without terminating the Agreement with respect to the remaining Collaboration Target at any time in its sole discretion by giving [***] advance written notice to Company (“Collaboration Target Termination Date”). Termination of a Collaboration Target by Merck under this Section can be effected only through a written notice specifically referring to this Section and identifying the Collaboration Target to be terminated. The terms of Section 9.2.2 shall apply with respect to the Terminated Collaboration Target (and Compounds and Licensed Products directed against such Terminated Collaboration Target) as of the Collaboration Target Termination Date.

by either Party upon the filing or institution of bankruptcy, reorganization, liquidation or receivership proceedings, or upon an assignment of a substantial portion of the assets for the benefit of creditors by the other Party; provided, however, that in the case of any involuntary bankruptcy proceeding such right to terminate shall only become effective if the Party consents to the involuntary bankruptcy or such proceeding is not dismissed within [***] after the filing thereof.

Effect of Termination for Cause on License.

In the event of termination under this Section 9.3:

all licenses granted by the Company to Merck under this Agreement shall automatically terminate effective as of the termination date of this Agreement;

Merck shall pay any amounts then due and owing as of the termination date;

any unused Materials and any derivatives, analogs, modifications or components thereof shall be, at the providing Party’s option, either promptly returned to the providing Party, or promptly destroyed in accordance with instructions by the providing Party (for clarity, any materials generated by a Party during the term of the Agreement that were not made using any Materials of the other Party, including cell lines, shall not be considered derivatives of the Materials of such other Party and shall not be subject to this Section 9.3.2(a)(iv));

Merck shall not, and shall ensure that its Affiliates, sublicensees and distributors shall not, sell, offer for sale or otherwise commercialize any Compounds or Licensed Products; and

No later than [***] after the effective date of termination under Section 9.3.1, each Party shall return or cause to be returned to the other Party all Information in tangible form received from the other Party and all copies thereof; provided, however, that each Party may retain any Information reasonably necessary for such Party’s continued practice under any license(s) which do not terminate pursuant to this Section 9.3, and may keep one copy of Information received from the other Party in its confidential files for record purposes or to demonstrate compliance

Except for the surviving provisions set forth in Section 9.5 and as otherwise set forth in this Section 9.3.2, the rights and obligations of the Parties hereunder shall terminate as of the date of a termination under Section 9.3.

If this Agreement is terminated by Merck pursuant to Section 9.3.1(c) due to the rejection of this Agreement by or on behalf of Company under Section 365 of the United States Bankruptcy Code (the “Code”), all licenses and rights to licenses granted under or pursuant to this Agreement by Company to Merck are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the Code, licenses of rights to “intellectual property” as defined under Section 101(35A) of the Code. The Parties agree that Merck, as a licensee of such rights under this Agreement, shall retain and may fully exercise all of its rights and elections under the Code, and that upon commencement of a bankruptcy proceeding by or against Company under the Code, Merck shall be entitled to a complete duplicate of or complete access to any such intellectual property and all embodiments of such intellectual property. Such intellectual property and all embodiments thereof shall be promptly delivered to Merck (i) upon any such commencement of a bankruptcy proceeding upon written request therefore by Merck, unless Company elects to continue to perform all of its obligations under this Agreement or (ii) if not delivered under (i) above, upon the rejection of this Agreement by or on behalf of Company upon written request therefore by Merck.

Alternative Remedy. If Merck has the right to terminate this Agreement pursuant to Section 9.3.1(a) as a result of Company’s uncured material breach [***] (subject to Company’s right to dispute as provided in Section 9.3.1(a)), then, in lieu of terminating this Agreement Merck may, in its sole discretion, exercise an alternative remedy as follows: Merck may retain all of its licenses and other rights granted under this Agreement with respect to Compounds and Licensed Products directed to such Collaboration Target, subject to all of its payment and other obligations herein continuing; except that the then-unearned milestone payments and royalties with respect to Compounds and Licensed Products directed to such Collaboration Target that become payable thereafter, in each case, will be reduced by [***]. If Merck avails itself of such election under this Section 9.4, the material breach giving rise to such election [***] and the reduction of its milestone and royalty obligations as set forth above in this paragraph shall be [***]. For the avoidance of doubt, except as expressly set forth in this Section 9.4, if Merck exercises the alternative remedy set forth in this Section 9.4, then all rights and obligations of both Parties under this Agreement will continue unaffected, unless and until this Agreement is subsequently terminated by either Party pursuant to Section 9.2 or 9.3.

Effect of Expiration or Termination; Survival. Expiration or termination of this Agreement shall not relieve the Parties of any obligation accruing prior to such expiration or termination. Any expiration or termination of this Agreement shall be without prejudice to the rights of either Party against the other accrued or accruing under this Agreement prior to expiration or termination, including without limitation the obligation to pay royalties for Licensed Product(s) or Compound sold prior to such expiration or termination. The provisions of Article 5 shall survive the expiration or termination of this Agreement and shall continue in effect for [***]. In addition, the provisions of Article 1, Article 5, Article 10, and Article 11, and Section 2.7, 2.9, 4.3, 6.6, 9.1, 9.2.2, 9.3.2, and 9.5 shall survive any expiration or termination of this Agreement.

Indemnification by Merck. Merck hereby agrees to defend, indemnify, and hold harmless Company and its Affiliates and their respective directors, officers, employees, and agents (each, a “Company Indemnitee”) from and against any and all liabilities, expenses, and losses, including reasonable legal expenses and attorneys’ fees (collectively, “Losses”), to which any Company Indemnitee may become subject as a result of any claim, demand, action, or other proceeding (each, a “Claim”) by any Third Party to the extent such Losses arise out of:

the research, development, use, manufacture, commercialization, or other disposition of any Compound or Licensed Product by Merck, its Affiliates or their respective subcontractors or sublicensees;

the negligence or willful misconduct of any Merck Indemnitee or Related Party; or

the breach by Merck of any term in or warranty, representation, or covenant made by Merck in this Agreement;

Indemnification by Company. Company hereby agrees to defend, indemnify, and hold harmless Merck and its Affiliates and their respective directors, officers, employees, and agents (each, a “Merck Indemnitee”) from and against any and all Losses to which any Merck Indemnitee may become subject as a result of any Claim by any Third Party to the extent such Losses arise out of:

the negligence or willful misconduct of any Company Indemnitee; or

the breach by Company of any term in or warranty, representation, or covenant made by Company in this Agreement;

Procedure.

The Party claiming indemnity under this Article 10 (the “Indemnified Party”) shall give written notice to the Party from whom indemnity is being sought (the “Indemnifying Party”) as soon as reasonably practicable after learning of such Claim, provided, that the failure or delay by an Indemnified Party to give such notice of a Claim shall not affect the indemnification provided hereunder except to the extent the Indemnifying Party has been materially prejudiced as a result of such failure or delay to give such notice.

The Indemnified Party shall provide the Indemnifying Party with reasonable assistance, at the Indemnifying Party’s expense, in connection with the defense of the Claim for which indemnity is being sought. The Indemnified Party may participate in and monitor such defense with counsel of its own choice at its own expense; provided, however, that the Indemnifying Party shall have the right to assume and conduct the defense of the Claim with counsel of its choice.

The Indemnifying Party shall not, without the prior written consent of the Indemnified Party, which consent shall not be unreasonably withheld, conditioned, or delayed, agree to any settlement of such Claim or consent to any judgment in respect thereof that does not include a complete and unconditional release of the Indemnified Party from all liability with respect thereto, that imposes any liability or obligation on the Indemnified Party, or that acknowledges fault by the Indemnified Party.

If the Indemnifying Party does not assume and conduct the defense of the Claim as provided above, the Indemnified Party shall control such defense and, without limiting the Indemnifying Party’s indemnification obligations, the Indemnifying Party will reimburse the Indemnified Party for all costs and expenses, including attorney fees, incurred by the Indemnified Party in defending itself within [***] after receipt of any invoice therefor from the Indemnified Party. The Indemnified Party shall not agree to any settlement of such Claim without the prior written consent of the Indemnifying Party, which shall not be unreasonably withheld, delayed or conditioned.

Insurance. During the Term, each Party, at its own expense, shall maintain commercial general liability insurance, including public and product liability and other appropriate insurance (or, in the case of Merck, self-insure) in an amount consistent with sound business practice and reasonable in light of its obligations under this Agreement. Each Party shall provide a certificate of insurance (or evidence of self-insurance) evidencing such coverage to the other Party upon request.

Force Majeure. Neither Party shall be held liable to the other Party nor be deemed to have breached this Agreement for failure or delay in performing any obligation under this Agreement (other than a failure to make a payment when due) to the extent such failure or delay is caused by or results from causes beyond the reasonable control of the affected Party, potentially including, but not limited to, pandemics, embargoes, war, acts of war (whether war be declared or not), acts of terrorism, insurrections, riots, civil commotions, strikes, lockouts or other labor disturbances, fire, floods or other acts of God, or acts, omissions or delays in acting by any governmental authority (other than for a failure to comply with applicable law). In the case of Merck’s obligations under Article 6, Merck shall not be held liable to Company or deemed to have defaulted under or breached this Agreement only to the extent that its delay in performing such obligations is caused by a temporary disruption in payment systems. The affected Party shall notify the other Party of such force majeure circumstances as soon as reasonably practical, and shall promptly undertake all reasonable efforts necessary to cure such force majeure circumstances.

Assignment/ Change of Control.

Assignment. Except as provided in this Section 11.2, this Agreement may not be assigned or otherwise transferred, nor may any right or obligation hereunder be assigned or transferred, by either Party without the consent of the other Party; provided, however, that either Party may, without such consent, assign this Agreement, in whole or in part, and its rights and obligations hereunder to an Affiliate or in connection with the transfer or sale of all or substantially all of its assets related to the subject matter of this Agreement, or in the event of its merger or consolidation or change in control or similar transaction. Any attempted assignment not in accordance with this Section 11.2 shall be void. Any permitted assignee shall assume all assigned obligations of its assignor under this Agreement. Company shall provide written notice to Merck within [***] after an assignment by Company.

Change of Control of Company.

Notwithstanding the provisions of Section 4.8, if Company undergoes a Change of Control during the term of this Agreement and, as of immediately prior to or following the closing of such Change of Control, any Person that becomes an Independent Affiliate of Company upon such Change of Control or any of such Person’s Affiliates existing immediately prior to such Change of Control or following such Change of Control other than the Company or Affiliates of Company existing prior to such Change of Control (collectively, the “Company Acquirer”) is researching, developing, manufacturing or commercializing any product, the research, development, manufacture or commercialization of which product in the Territory would, but for the provisions of this Section 11.2.2 constitute a breach of Section 4.8 (such product, a “Distracting Product”), then Company will not be in breach of Section 4.8 as a result of such activities with respect to any such Distracting Product (provided that, with respect to Distracting Products that arise after such Change of Control, the Company Acquirer does not access or use any confidential know-how Controlled by Company prior to such Change of Control in the conduct of activities related to such Distracting Product), and Company or the Company Acquirer, as applicable, will, (i) adopt reasonable procedures to segregate all research, development or commercialization activities relating to the Distracting Product from research, development and commercialization with respect to Compounds and Licensed Products under this Agreement, and conduct any activities under the Research Program separately from all activities relating to the Distracting Product, including through the maintenance of separate lab notebooks and records; and (ii) establish reasonable firewall protections and safeguards designed to ensure the activities of its personnel under the Research Program are segregated from all activities relating to the Distracting Product, including reasonable efforts to ensure that (x) none of its personnel involved in performing development or commercialization activities with respect to the Distracting Product have access to non-public plans or information relating to the development or commercialization of Compounds or Licensed Products under this Agreement and (y) none of its personnel involved in performing development activities under the Research Program with respect to the Compounds or Licensed Products under this Agreement have access to non-public plans or information relating to the development or commercialization of the Distracting Product (except, in each case, that management personnel may [***]).

Upon a Change of Control of Company, Company shall adopt reasonable procedures to be agreed upon in writing with Merck to prevent the disclosure of all information of Merck and its Affiliates and other information with respect to development and commercialization of Compounds and Licensed Products to Company personnel dedicated to the development and commercialization of any Distracting Product. Upon such Change of Control, Merck’s obligation to provide royalty reports pursuant to Section 6.5 shall be limited to reporting Merck’s total worldwide royalty obligations and Merck shall no longer be obligated to provide Development Reports pursuant to Section 4.6.

Use of Affiliates. Each of Company and Merck shall have the right to exercise its rights and perform its obligations under this Agreement either itself or through any of its respective Affiliates, provided, however, that each Party shall remain responsible for the performance of its Affiliates and shall cause such Affiliates to comply with the provisions of this Agreement in connection with such performance, including the provisions addressing confidentiality and non-use. Any breach by a Party’s Affiliate of any of such Party’s obligations under this Agreement shall be deemed a breach by such Party, and the other Party may proceed directly against such Party without any obligation to first proceed against such Party’s Affiliate.

Severability. If any one or more of the provisions contained in this Agreement is held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby, unless the absence of the invalidated provision(s) adversely affects the substantive rights of the Parties. The Parties shall in such an instance use reasonable efforts to replace the invalid, illegal or unenforceable provision(s) with valid, legal and enforceable provision(s) which, insofar as practical, implement the purposes of this Agreement.

Notices. All notices which are required or permitted hereunder shall be in writing and sufficient if delivered personally, sent by email (and promptly confirmed by personal delivery, registered or certified mail or overnight courier), sent by nationally-recognized overnight courier or sent by registered or certified mail, postage prepaid, return receipt requested, addressed as follows:

Applicable Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York without reference to any rules of conflict of laws. This Agreement was prepared in the English language, which language shall govern the interpretation of, and any dispute regarding, the terms of this Agreement.

Dispute Resolution.

The Parties shall negotiate in good faith and use reasonable efforts to settle any dispute, controversy or claim arising from or related to this Agreement or the breach thereof (a “Dispute”). Any Party shall give the other Party written notice of any Dispute not resolved in the normal course of business. Within [***] from the date of delivery of such notice, the receiving Party shall submit to the other Party a written response. The notice and response shall include (A) a statement of that Party’s position and a summary of arguments supporting that position, and (B) the name and title of the executive who will represent that Party and of any other person who will accompany the executive. Within [***] from the date of delivery of the initial notice, the executives of both Parties shall meet at a mutually acceptable time and place, and thereafter as often as they reasonably deem necessary, to attempt to resolve the Dispute. These executives shall have the authority to settle the Dispute and shall be at a higher level of management than the persons with direct responsibility for administration of this Agreement. All negotiations pursuant to this paragraph are confidential and shall be treated as compromise and settlement negotiations for purposes of applicable rules of evidence.

If the Parties do not fully settle following the procedure in Section 11.7.1, and a Party wishes to pursue the matter, each dispute, controversy or claim arising from or related to this Agreement or the breach thereof that is not an Excluded Claim shall be finally resolved by binding arbitration in accordance with this Section 11.7.2. Such Dispute shall be referred to and finally resolved by arbitration under the American Arbitration Association (“AAA”) rules, as then in effect, by a tribunal of three (3) arbitrators. The seat and legal place of the arbitration shall be New York City, New York. Each Party shall nominate one arbitrator and the third arbitrator shall be nominated by the two Party-nominated arbitrators within [***] after the second arbitrator’s appointment. If a Party does not nominate its arbitrator within [***] following the expiry of the allotted period, then such arbitrator shall be appointed by the AAA in accordance with its rules. Any arbitrator appointed by the AAA shall have at least [***] experience in the pharmaceutical industry. The arbitration shall be conducted, and all documents submitted to the arbitrators shall be, in English. Each Party shall bear its own legal costs for its counsel and other expenses, and the Parties shall equally share the costs of the arbitration unless the arbitrators otherwise determine, and in such case the arbitral award will so provide. Tfhe arbitrators shall have no power to award damages excluded pursuant to Section 11.8. In no event shall the arbitrators assign a value to any issue greater than the greatest value for such issue claimed by either Party or less than the smallest value for such issue for such item claimed by either Party. The award shall be final and binding upon the Parties and the Parties undertake to carry out any award without delay. Judgment on the award may be entered in any court of competent jurisdiction. Except to the extent necessary to confirm, enforce, or challenge an award of the arbitration, to protect or pursue a legal right, or as otherwise required by applicable law or regulation or securities exchange, neither Party nor any arbitrator may disclose the existence, content, or results of any arbitration hereunder without the prior written consent of both Parties. Notwithstanding anything to the contrary in the foregoing, in no event shall an arbitration be initiated after the date when commencement of a legal or equitable proceeding based on the dispute, controversy, or claim would be barred by the applicable New York statute of limitations. Any disputes concerning the propriety of the commencement of the arbitration shall be finally settled by the arbitral tribunal.

The arbitrators shall have no power to grant interim or permanent injunctive relief. Notwithstanding anything herein to the contrary, each Party shall have the right to seek to institute judicial proceedings against the other Party, or anyone acting by, through or under such other Party, in order to seek interim or provisional relief, including specific performance, a preliminary injunction or other similar interim equitable relief, concerning a dispute in any court of competent jurisdiction before or after the initiation of an arbitration as set forth in Section 11.7.2, if necessary to protect the interests of such Party. This Section shall be specifically enforceable.

The Parties agree that, in the event of a good faith dispute over the nature or quality of performance under this Agreement, neither Party may terminate this Agreement until final resolution of the dispute through arbitration pursuant to Section 11.7.2. The Parties further agree that any payments made pursuant to this Agreement pending resolution of the dispute shall be refunded if an arbitrator determines that such payments are not due.

As used in this Section, the term “Excluded Claim” shall mean a dispute, controversy or claim that concerns (a) a decision by the Committee or Merck within the proper scope of the Committee’s authority pursuant to Section 2.3, or an issue concerning the integrity of data submitted to a regulatory agency, neither of which shall be arbitrable or justiciable in any forum; (b) the validity or infringement of a patent, trademark or copyright; or (c) any antitrust, anti-monopoly or competition law or regulation, whether or not statutory. Any action concerning Excluded Claims identified in clauses (b) and (c) of this Paragraph may be brought in any court having jurisdiction.

Limitation of Liability. EXCEPT FOR DAMAGES THAT ARISE IN CONNECTION WITH A PARTY’S WILLFUL MISCONDUCT OR FRAUD OR BREACH OF ITS OBLIGATIONS UNDER ARTICLE 5, NEITHER PARTY SHALL BE LIABLE IN CONTRACT, TORT, NEGLIGENCE, BREACH OF STATUTORY DUTY, OR OTHERWISE FOR ANY SPECIAL, INCIDENTAL, INDIRECT, PUNITIVE, OR CONSEQUENTIAL DAMAGES OR FOR LOSS OF PROFITS OR LOST SALE DAMAGES OF ANY KIND SUFFERED BY THE OTHER PARTY (OR ITS AFFILIATES), REGARDLESS OF ANY NOTICE OF THE POSSIBILITY OF SUCH DAMAGES. NOTHING IN THIS SECTION 11.8 SHALL BE CONSTRUED TO LIMIT EITHER PARTY’S INDEMNIFICATION OBLIGATIONS UNDER ARTICLE 10.

Entire Agreement; Amendments. This Agreement, together with the Schedules and Exhibits hereto, contains the entire understanding of the Parties with respect to the subject matter hereof. Any other express or implied agreements and understandings, negotiations, writings and commitments, either oral or written, with respect to the subject matter hereof are superseded by the terms of this Agreement. The Schedules and Exhibits to this Agreement are incorporated herein by reference and shall be deemed a part of this Agreement. This Agreement may be amended, or any term hereof modified, only by a written instrument duly executed by authorized representative(s) of both Parties hereto.

Headings. The captions to the several Articles, Sections and subsections hereof are not a part of this Agreement, but are merely for convenience to assist in locating and reading the several Articles and Sections hereof.

Independent Contractors. It is expressly agreed that Company and Merck shall be independent contractors and that the relationship between the two Parties shall not constitute a partnership, joint venture or agency. Neither Company nor Merck shall have the authority to make any statements, representations or commitments of any kind, or to take any action, which shall be binding on the other Party, without the prior written consent of the other Party.

Waiver. The waiver by either Party hereto of any right hereunder, or of any failure of the other Party to perform, or of any breach by the other Party, shall not be deemed a waiver of any other right hereunder or of any other breach by or failure of such other Party whether of a similar nature or otherwise. No waiver shall be valid unless in writing and signed by the waiving Party.

Waiver of Rule of Construction. Each Party has had the opportunity to consult with counsel in connection with the review, drafting and negotiation of this Agreement. Accordingly, the rule of construction that any ambiguity in this Agreement shall be construed against the drafting Party shall not apply.

Certain Conventions. Any reference in this Agreement to an Article, Section, subsection, paragraph, clause, Schedule or Exhibit shall be deemed to be a reference to an Article, Section, subsection, paragraph, clause, Schedule or Exhibit, of or to, as the case may be, this Agreement, unless otherwise indicated. Whenever this Agreement refers to a number of days, unless otherwise

Business Day Requirements. In the event that any notice or other action or omission is required to be taken by a Party under this Agreement on a day that is not a Business Day, then such notice or other action or omission shall be deemed to be required to be taken on the next occurring Business Day.

Counterparts. This Agreement may be signed in any number of counterparts (including by facsimile or electronic transmission), each of which shall be deemed an original, but all of which shall constitute one and the same instrument. After facsimile or electronic transmission, the Parties agree to execute and exchange documents with original signatures.
