Article 4.

Licensed Product Matters

4.1.

Licensed Targets; Target Selection.

4.1.1.

Initial Licensed Targets. As of the Effective Date, Schedule 1.127(a) sets forth the two (2) Initial Licensed Targets designated by CRISPR. For the avoidance of doubt, each such Initial Licensed Target is not (a) [***] or (b) subject to Section 4.1.6 with respect to [***], the subject of [***].

4.1.2.

Licensed Target Substitution. [***], CRISPR may elect to substitute either or both of the two (2) Initial Licensed Targets (or any subsequent Licensed Target) with [***] upon written notice to Sirius (the “Substitution Notice”); provided that (a) CRISPR [***] Target or [***] Target ([***]) for a Licensed Target without Sirius’ written consent, and (b) CRISPR shall not be permitted to substitute Licensed Targets more than [***] times in the aggregate (the “Substitution Cap”). Subject to Sections 2.1.3 and 2.1.5, the Parties will develop a Research Plan for such Licensed Target and the JSC will review such plan and agree upon a final Research Plan for such Licensed Target. For the purpose of this Agreement, (i) [***] and (ii) [***].

4.1.3.

Reserved Licensed Target List. A list of five (5) Targets selected by CRISPR (each such Target, a “Reserved Target,” and collectively, the “Reserved Targets” and such list, the “Reserved Licensed Target List”) is attached to this Agreement as Schedule 1.127(b). CRISPR may remove Targets from the Reserved Licensed Target List upon providing a Substitution Notice to Sirius and thereafter such removed Target will no longer be a Reserved Target. For the avoidance of doubt, each such Reserved Target is not (a) [***], or (b) [***].

4.1.4.

[***] Target Update. If a proposed Target is not selected as a substitute Licensed Target due to it being [***] Target, such Target will not count against the Substitution Cap. If, during the Nomination Period, such Target ceases to be [***] Target, Sirius will promptly notify CRISPR that such Target is no longer [***] Target, and, thereafter, subject to the Substitution Cap, CRISPR may at its option (exercisable at any time within [***] days of CRISPR’s receipt that such Target is no longer [***] Target) replace a Licensed Target with such Target.

4.1.5.

Subcontracting.

6.1.1.

Research Program; Licensed Product Candidates and Licensed Products. Each Party may subcontract the performance of any activities undertaken by such Party with respect to a Research Program, Research Plans, Licensed Product Candidates or Licensed Products hereunder, including CMOs, contract research organizations and Distributors (each such Third Party, a “Subcontractor”) pursuant to a written agreement consistent with the provisions of this Agreement (a “Subcontract”). Notwithstanding the foregoing, if either Party desires to subcontract any such activities, it will first discuss the matter with the other Party and reasonably consider using the other Party for such subcontracted activities, taking into account the capabilities of the other Party and potential impact on costs, as a potential alternative to subcontracting such activities to a Third Party. If, following such discussion a Party still desires to subcontract the performance of any such activity to one or more Third Parties, it may proceed to do so.

6.1.2.

Collaboration Program. Each Partnership Party may subcontract the performance of any activities undertaken by such Partnership Party in accordance with the Global Development Plan, Global Manufacturing Plan, Global Medical Affairs Plan, Global Commercialization Plans or Regional Commercialization Plans to one or more Subcontractor pursuant to a Subcontract. Notwithstanding the foregoing, if either Partnership Party desires to subcontract any such activities, it will first discuss the matter with the other Partnership Party and reasonably consider using the other Partnership Party for such subcontracted activities, taking into account the capabilities of the other Partnership Party and potential impact on costs, as a potential alternative to subcontracting such activities to a Third Party. If, following such discussion a Partnership Party still desires to subcontract the performance of any such activity to one or more Third Parties, it may proceed to do so; provided, that prior to entering into any Subcontract which the subcontracting Partnership Party reasonably anticipates will entail payments to the Subcontractor in excess of [***] Dollars ($[***]) with respect to subcontracted activities under this Agreement that would be Collaboration Program Expenses, the subcontracting Partnership Party will obtain the applicable Committee’s approval, not to be unreasonably withheld, delayed or conditioned to the extent within the scope of an agreed budget for such activities, of use of the proposed Subcontractor to conduct the activities proposed to be subcontracted prior to execution of the applicable Subcontract. For clarity, the foregoing shall not apply to any Subcontractor already engaged by Sirius-US or its Affiliates prior to the Effective Date and set forth on Schedule 3.1.2(c)(ii) or Schedule 3.4.5(a) attached hereto.

6.1.3.

General. Each Party will be responsible for the effective and timely management of and payment of its Subcontractors. The engagement of any Subcontractor in compliance with this Article 6 will not relieve the applicable Party of its obligations under this Agreement or the Research Plan, Global Development Plan, Global Manufacturing Plan, Global Medical Affairs Plan, Global Commercialization Plan or Regional Commercialization Plan. The Parties will each be solely responsible for any taxes, including income, withholding, payroll, VAT, sales tax or the like, that arise from their respective use of a Subcontractor.

Collaboration Products.

7.2.1.

Allocation. Following the [***] Date, each Partnership Party will be entitled to fifty percent (50%) of the Collaboration Product Revenue with respect to a Collaboration Product for each Calendar Quarter starting on First Commercial Sale of such Collaboration Product and continuing during the Collaboration Products Term for so long as such Collaboration Product is Commercialized in the Field in the Territory, or until either Partnership Party elects to Opt-Out with respect to Collaboration Product. If either Partnership Party elects to Opt-Out, the other Partnership Party shall pay Opt-Out Milestone Payments and Opt-Out Royalties with respect to the Opt-Out Product following such Opt-Out in accordance with Section 10.3. Subject to either Partnership Party’s election to Opt-Out, unless otherwise agreed to by the Partnership Parties and specified in the Global Development Plan, Global Manufacturing Plan, Global Medical Affairs Plan, Global

Commercialization Plan or Regional Commercialization Plan, as applicable, and an Integrated Budget with respect to a Collaboration Product, each Partnership Party will be responsible for bearing expenses incurred after the [***] Date for such Collaboration Product as follows: (i) for Collaboration Program Expenses incurred for such Collaboration Product, each Partnership Party will be allocated fifty percent (50%) of such Collaboration Program Expenses; and (ii) [***].

Calculation. Collaboration Product Revenues and Collaboration Program Expenses will be calculated for each Calendar Quarter, as applicable.

7.2.3.

Payment of Expenses; Summary Statements. Subject to reconciliation and the limitations provided in Section 7.2.4, the Partnership Party initially incurring Collaboration Program Expenses will be responsible for and pay for all such Collaboration Program Expenses so incurred. Each Partnership Party will maintain the books and records referred to in Section 7.2.6. Each Partnership Party will report all Collaboration Program Expenses and Collaboration Product Revenues in accordance with the terms and conditions hereof and in accordance with GAAP. If any Collaboration Program Expenses relate to multiple Collaboration Products, the Partnership Parties will work together to determine an equitable allocation of such Collaboration Program Expenses between such Collaboration Products. Within [***] Business Days after the end of each Calendar Quarter, each Partnership Party will submit to the other a written report reflecting, on a Collaboration Product-by-Collaboration Product basis, the estimated Collaboration Program Expenses and Collaboration Product Revenues during the just-ended Calendar Quarter, except that each Partnership Party’s submission for the last month of such Calendar Quarter will be a good faith estimate and not actual amounts (each, a “Summary Statement”). Each Summary Statement (after the initial Summary Statement) will reflect an adjustment for the actual amount of the previous Calendar Quarter as needed; provided that, if, prior to preparation of a Summary Statement in accordance with the preceding sentence, a Partnership Party discovers that actual Collaboration Program Expenses or Collaboration Product Revenues have either (i) deviated materially from any non-binding, good faith estimate of such Collaboration Program Expenses or Collaboration Product Revenues submitted to the other Partnership Party in accordance with this Section 7.2.3, or (ii) deviated by more than [***] from the aggregate amounts for such Collaboration Program Expenses or Collaboration Product Revenues in the most recently agreed Integrated Budget therefor, or any deviation in any single Expense of more than [***] dollars ($[***]) from the amount included in the most recently agreed Integrated Budget therefor, then such Party shall promptly notify the other Partnership Party of such deviation in advance of delivery of such Summary Statement. Any reporting and reconciliation of variances between estimated and actual Expenses may be delayed by a Calendar Quarter as reasonably necessary in light of a Partnership Party’s internal reporting procedures. The

Partnership Parties’ respective Summary Statements will serve as the basis of the Reconciliation Reports prepared by the Parties pursuant to Section 7.2.4. The Partnership Parties’ respective finance departments, coordinated by Alliance Managers, will meet at least [***] per month, or as otherwise mutually agreed by the Partnership Parties, to discuss any questions or issues arising from the Summary Statements, including the basis for the recognition of specific Collaboration Program Expenses, review cost estimates and forecasts, and discuss reconciliation and reporting procedures.

7.2.4.

Reconciliation. CRISPR will prepare a reconciliation report, as soon as practicable after the receipt of the other Partnership Party’s Summary Statement, but in any event no later than [***] days after the end of each Calendar Quarter, accompanied by reasonable supporting documents and calculations sufficient to support each Partnership Party’s financial reporting obligations, independent auditor requirements and obligations under the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act, which reconciles the amounts accrued and reported in each Partnership Party’s Summary Statement during such Calendar Quarter and the share of the Collaboration Product Revenue and Collaboration Program Expenses with respect to such applicable Collaboration Products to be allocated to each of the Partnership Parties for such Calendar Quarter in accordance with Section 7.2.1 (such report, the “Reconciliation Report”).

7.2.5.

Upon completion of the audit, the accounting firm will provide both the Auditing Party and the Audited Party a written report

disclosing whether the applicable Summary Statements, Reconciliation Reports, Research Expense Statements and Royalty Reports, as applicable, are correct or incorrect and the specific details concerning any discrepancies. No other information will be provided to the Auditing Party. If the report or information submitted by the Audited Party results in an underpayment or overpayment, the Party owing underpaid or overpaid amount will promptly pay such amount to the other Party (together with any interest accrued pursuant to Section 7.8), and, if, as a result of such inaccurate report or information, such amount of underpayment by the Audited Party to the Auditing Party is more than [***] of the amount that was owed, the Audited Party will reimburse the Auditing Party for the reasonable expense incurred by the Auditing Party in connection with the audit.

7.6.

Payment Method; Currency. All cash payments under this Agreement will be paid in U.S. Dollars, by wire transfer. All payments in CRISPR Common Stock shall be at a price per share determined pursuant to the Share Issuance Agreement and are subject to Sirius’ execution and delivery to CRISPR of a mutually agreeable stock purchase or subscription agreement.

7.7.

Exchange Rate; Manner and Place of Payment. All references to dollars and “$” herein shall refer to U.S. dollars. When conversion of payments from any currency other than U.S. dollars is required, such conversion shall be at an exchange rate equal to the weighted average of the rates of exchange for the currency of the country from which such payments are payable as published by The Wall Street Journal, Eastern U.S. Edition, during the Calendar Quarter in which the applicable sales were made or Collaboration Program Expenses or Research Program Expenses are incurred. All payments owed under this Agreement shall be made by wire transfer in immediately available funds to a bank and account designated in writing by the applicable Party. Each Party shall be responsible for all wire transfer fees incurred in connection with its payments to the other Party under this Agreement.

7.8.

Late Payment. Any undisputed payments or portions thereof due hereunder that are not paid when due will accrue interest from the date due until paid at an annual rate equal to [***] (or the maximum allowed by Applicable Law, if less).

7.9.

Taxes; Withholding.

7.9.1.

[***].

7.9.2.

Any Party may withhold from payments due to any other Party (or allocable to a Partnership Party) amounts for payment of any withholding tax that is required by Applicable Law to be paid to any taxing authority with respect to such payments or allocations. In such case, the payor Party will provide to the payee Party all relevant documents and correspondence, and will also provide to the payee Party any other cooperation or assistance on a commercially reasonable basis as may be necessary to enable the payee Party to claim exemption from such withholding. The payor Party will give proper evidence from time to time as to the payment of any such tax. The Parties will cooperate with each other in seeking deductions under any double taxation or other similar treaty or agreement from time to time in force. For the avoidance of doubt, the withholding provisions of Section

1.4.3 of Exhibit C shall apply to any payments made pursuant to this Article 7. The Parties acknowledge and agree that to the extent amounts are withheld in accordance with this Section 7.9 or Section 1.4.3 of Exhibit C, any amounts so withheld shall be treated as paid pursuant to Section 1.4.1 or Section 1.4.2 of Exhibit C and Section 7.1 of this Agreement, as applicable. The Parties acknowledge that as of the Effective Date no withholding tax is applicable to the Upfront Consideration payable pursuant to Section 7.1.

7.9.3.

[***].

7.9.4.

Notwithstanding the foregoing, the Parties acknowledge and agree that if the paying Party (or any person paying on its behalf) is required by Applicable Law to withhold taxes in respect of any payment due under this Agreement, and if such withholding obligation arises or is increased solely as a result any action by the paying Party (or any person paying on its behalf) after the Effective Date, including, without limitation, any assignment of this Agreement by the paying Party, a Change of Control of the Paying Party, or the paying Party exercising its rights or performing its obligations or duties under this Agreement through an Affiliate (each, a “Withholding Tax Action”), then, notwithstanding anything to the contrary herein, any such payment shall be increased to take into account such increased withholding taxes as may be necessary so that, after making all required withholdings (including any withholdings on additional amounts), the receiving Party receives an amount equal to the sum it would have received had no such Withholding Tax Action occurred. If a Governmental Authority retroactively determines that a payment made by a Party to the other Party pursuant to this Agreement should have been subject to withholding or similar (or to additional withholding or similar) taxes, and such Party (the “Withholding Party”) remits such withholding or similar taxes to the Governmental Authority, including any interest and penalties that may be imposed thereon but excluding any penalties and interest due to such Party’s negligence (together with the tax paid, the “Withholding Amount”), the Withholding Party shall have the right (a) to offset the Withholding Amount against future payment obligations of the Withholding Party under this Agreement, (b) to invoice the other Party for the Withholding Amount (which shall be payable by the other Party within [***] days of its receipt of such invoice), or (c) to pursue reimbursement of the Withholding Amount by any other available remedy.

7.9.5.

All payments under this Agreement are exclusive of value added taxes, sales taxes, consumption taxes and other similar taxes (the “Indirect Taxes”). Where any sum due to be paid to either Party hereunder is or would otherwise be subject to any Indirect Tax, the Parties shall reasonably cooperate with each other and use their commercially reasonable efforts to take all actions as will enable them to secure any available exemption from or reduction in such Indirect Tax. If any Indirect Taxes are chargeable in respect of any payments under this Agreement, the paying Party shall pay such Indirect Taxes at the applicable rate in respect of such payments following receipt, where applicable, of an Indirect Taxes invoice in the appropriate form issued by the receiving Party in respect of those payments. The Parties shall issue invoices for all amounts payable under this

Agreement consistent with Indirect Tax requirements and irrespective of whether the sums may be netted for settlement purposes. If the Indirect Taxes originally paid or otherwise borne by the paying Party are in whole or in part subsequently determined not to have been chargeable, the receiving Party shall use commercially reasonable efforts to take all necessary steps to receive a refund of these undue Indirect Taxes from the applicable Governmental Authority or other fiscal authority and any amount of undue Indirect Taxes repaid by such authority to the receiving Party shall be transferred to the paying Party within [***] days of receipt. For the avoidance of doubt, this provision shall not apply to expenses borne and shared by the Partnership Parties pursuant to Section 7.2.1.

7.10.

Foreign Derived Tangible Income. Each Party shall use commercially reasonable efforts to provide, and to cause its subcontractors, sublicensees, customers and applicable Third Parties to provide, any information and documentation reasonably needed by a Party to obtain the benefits of Section 250 of the Code and the applicable Treasury Regulations or in seeking any other exemption, deduction, credit or similar tax benefit that may be available to a Party, including without limitation information required to demonstrate the extent to which the Collaboration Products will be sold, consumed, used and/or manufactured outside the United States.

Article 9.

Indemnification; Insurance

9.1.

Indemnification by Sirius. Sirius will indemnify, defend and hold harmless CRISPR, each of its Affiliates, and each of its and its Affiliates’ respective employees, officers, directors and agents (each, a “CRISPR Indemnified Party”) from and against any and all liability, loss, damage, expense (including reasonable attorneys’ fees and expenses) and cost (collectively, a “Liability”) that any CRISPR Indemnified Party may be required to pay to one or more Third Parties to the extent resulting from or arising out of any claim by any Third Party based on:

9.1.1.

[***];

9.1.2.

[***];

9.1.3.

[***];

9.1.4.

[***]; or

9.1.5.

[***].

except, in each case, to the extent CRISPR is required to indemnify Sirius pursuant to Section 9.2.

9.2.

Indemnification by CRISPR. CRISPR will indemnify, defend and hold harmless Sirius, each of its Affiliates, and each of its and its Affiliates’ respective employees, officers, directors and agents (each, a “Sirius Indemnified Party”) from and against any and all Liabilities that any Sirius Indemnified Party may be required to pay to one or more Third Parties to the extent resulting from or arising out of any claim by any Third Party based on:

9.2.1.

[***];

9.2.2.

[***];

9.2.3.

[***];

9.2.4.

[***]; or

9.2.5.

[***].

except, in each case, to the extent Sirius is required to indemnify CRISPR pursuant to Section 9.1.

9.3.

Procedure. Each Party will notify the other Party in writing if it becomes aware of a claim for which indemnification may be sought hereunder. In case any proceeding (including any governmental investigation) will be instituted involving any Party in respect of which indemnity may be sought pursuant to this Article 9, such Party (the “Indemnified Party”) will give prompt written notice of the indemnity claim to the other Party (the “Indemnifying Party”) and provide a copy to the Indemnifying Party of any complaint, summons or other written or verbal notice that the Indemnified Party receives in connection with any such claim. An Indemnified Party’s failure to deliver written notice will relieve the Indemnifying Party of liability to the Indemnified Party under this Article 9 only to the extent such delay is prejudicial to the Indemnifying Party’s ability to defend such claim. Provided that the Indemnifying Party is not contesting the indemnity obligation, the Indemnified Party will permit the Indemnifying Party to control any litigation relating to such claim and the disposition of such claim by negotiated settlement or otherwise and any failure to contest prior to assuming control will be deemed to be an admission of the obligation to indemnify. The Indemnifying Party will act reasonably and in good faith with respect to all matters relating to such claim and will not settle or otherwise resolve such claim without the Indemnified Party’s prior written consent which will not be unreasonably withheld, delayed or conditioned other than settlements only involving the payment of monetary awards for which the Indemnifying Party will be fully-responsible. The Indemnified Party will cooperate with the Indemnifying Party in such Party’s defense of any claim for which indemnity is sought under this Agreement, at the Indemnifying Party’s sole cost and expense.

9.4.

Other Third Party Claims for Products. If a Third Party brings a claim of any nature arising out of the Research, Development, Manufacture, Commercialization or use of any of the Products, other than claims for which a Party has indemnification obligations pursuant to Section 9.1 or Section 9.2, the Party that is named as a defendant in such claim will have the right to defend itself against such claim. The other Party will reasonably assist the defending Party in defending the claim and cooperate in any such litigation. The defending Party will provide the other Party with prompt written notice of the receipt of any such claim and will keep the other party apprised of the progress of such claim and will promptly furnish the other Party with a copy of the claim. The defending Party will not enter into any settlement agreement with such Third Party without the other Party’s prior written consent, not to be unreasonably withheld, delayed or conditioned. If both Parties are named as defendants in any claim, both Parties may defend such claim and the Parties will reasonably cooperate with respect to such defense. [***].

9.5.

The cancelling or non-renewing Party will obtain replacement insurance providing comparable coverage prior to the expiration of such [***]-day period.

9.5.3.

Post-Termination Obligations. Each Party will maintain the insurance required under this Section 9.5 beyond the expiration or termination of this Agreement for a reasonable period after the period during which either Party or its Affiliates or Sublicensees is Developing or Commercializing any Product, which in no event will be less than [***].

9.5.4.

Affiliates, Sublicensees. Each Party will (i) ensure that all applicable Affiliates of such Party are covered under such Party’s insurance policies as described in Section 9.5 and (ii) require all of its Sublicensees and distributors to comply with the provisions and obligations under this Section 9.5 as if such entity were such Party.

9.5.5.

No Limitation. The minimum amounts of insurance coverage required under this Section 9.5 will not be construed to create a limit of liability with respect to a Party’s indemnification obligations under Section 9.1 or Section 9.2, as applicable.

9.5.6.

Self-Insurance. Notwithstanding the foregoing, a Party may self-insure to the extent that it self-insures for its other activities.

(b)

CRISPR’s Right to Terminate. If Sirius is in material breach of this Agreement, then CRISPR may deliver written notice of such material breach to Sirius.

10.2.4.

Termination for Insolvency.

(a)

If either Party makes an assignment for the benefit of creditors, appoints or suffers appointment of a receiver or trustee over all or substantially all of its property, files a petition under any bankruptcy or insolvency act or has any such petition filed against it that is not discharged within [***] days of the filing thereof (each, an “Insolvency Event”), then the other Party may terminate this Agreement in its entirety effective immediately upon written notice.

(b)

This Section 10.2.4(b) and Section 10.2.4(c) shall apply in the event this Agreement is not terminated. All rights and licenses now or hereafter granted by a Party under or pursuant to this Agreement are, for all purposes of Section 365(n) of the U.S. Bankruptcy Code, licenses of rights to “intellectual property” as defined in the U.S. Bankruptcy Code. Upon the occurrence of any Insolvency Event with respect to a Party (the “Licensor Party”), the Licensor Party agrees that the other Party (the “Licensee Party”), as licensee of such rights under Section 5.2 or Section 5.3 of this Agreement, as applicable, will retain and may fully exercise all of its rights and elections under the U.S. Bankruptcy Code. The Licensor Party will, during the Term, create and maintain current copies or, if not amenable to copying, detailed descriptions or other appropriate embodiments, to the extent feasible, of all intellectual property licensed under this Agreement.

If (i) a case under the U.S. Bankruptcy Code is commenced by or against a Licensor Party, (ii) this Agreement is rejected as provided in the U.S. Bankruptcy Code, and (iii) the Licensee

101

Party elects to retain its rights hereunder as provided in Section 365(n) of the U.S. Bankruptcy Code, the Licensor Party (in any capacity, including debtor-in-possession) and its successors and assigns (including a trustee) will:

(i)

provide to the Licensee Party all such intellectual property licensed to the Licensee Party under Section 5.2 or Section 5.3 of this Agreement, as applicable (including all embodiments thereof), held by the Licensor Party and such successors and assigns, or otherwise available to them, immediately upon the Licensee Party’s written request. Whenever the Licensor Party or any of its successors or assigns provides to the Licensee Party any of the intellectual property licensed hereunder (or any embodiment thereof) pursuant to this Section 10.2.4, the Licensee Party will have the right to perform the Licensor Party’s obligations hereunder with respect to such intellectual property, but neither such provision nor such performance by the Licensee Party will release the Licensor Party from liability resulting from rejection of the license or the failure to perform such obligations; and

(ii)

not interfere with the Licensee Party’s rights under this Agreement, to such intellectual property licensed to the Licensee Party under Section 5.2 or Section 5.3 of this Agreement, as applicable (including such embodiments), including any right to obtain such intellectual property (or such embodiments) from another entity, to the extent provided in Section 365(n) of the U.S. Bankruptcy Code.

(c)

All rights, powers and remedies of the Licensee Party provided herein are in addition to and not in substitution for any and all other rights, powers and remedies now or hereafter existing at law or in equity (including the U.S. Bankruptcy Code) in the event of the commencement of a case under the U.S. Bankruptcy Code with respect to the Licensor Party. The Parties agree that they intend the following rights to extend to the maximum extent permitted by Applicable Law, and to be enforceable under U.S. Bankruptcy Code Section 365(n):

(i)

the right of access to any intellectual property rights licensed to the Licensee Party under Section 5.2 or Section 5.3 of this Agreement, as applicable (including all embodiments thereof), by the Licensor Party, or any Third Party with whom the Licensor Party contracts to perform an obligation of the Licensor Party under this Agreement, and, in the case of any such Third Party, which is necessary for the Research Activities and the Development, Manufacture, use, sale, import or export of Products, as applicable; and

Opt-Out. On a Collaboration Product-by-Collaboration Product basis, either Partnership Party may opt out of all activities with respect to such Collaboration Product pursuant to this Agreement (an “Opt-Out Product”) upon [***] days’ written notice to the other Partnership Party (“Opt-Out”); provided that neither Partnership Party may exercise its right to Opt-Out for any Collaboration Product until the later of (a) [***] months after the Effective Date or (b) the date on which [***] is achieved; provided further, [***]. For clarity, the date that the

102

Opt-Out Notice is sent with respect to a Product shall be the “Opt-Out Notice Date” and the date that is [***] days after the Opt-Out Notice Date shall be the effective date of Opt-Out (the “Opt-Out Effective Date”). The Partnership Party that exercises its right to Opt-Out is referred to as the “Opt-Out Party” and the other Partnership Party is referred to as the “Continuing Party”. The Opt-Out Product shall no longer be considered a Collaboration Product for purposes of this Agreement. For clarification, in the event of an Opt-Out, the Continuing Party may continue activities with respect to the Opt-Out Product or may discontinue activities with respect to the Opt-Out Product, and the Continuing Party may terminate this Agreement with respect to the Opt-Out Product upon [***] days’ written notice to the Opt-Out Party.

10.3.1.

HSR Determination. Within [***] days following the receipt of the Opt-Out notice from the Opt-Out Party, the Continuing Party shall notify, in writing, the Opt-Out Party whether an HSR Filing is necessary (“HSR Determination Notification”), and if an HSR Filing is necessary, each Partnership Party shall as promptly as possible, but in no event later than [***] days following the Opt-Out Party’s receipt of the HSR Determination Notification, (or such later time as may be agreed to in writing by the Partnership Parties), file with the FTC and the DOJ, any HSR Filing required of it under the HSR Act with respect to the relevant Opt-Out. The Partnership Parties shall cooperate with one another to the extent necessary in the preparation of any such HSR Filing. Each Partnership Party will use its respective Commercially Reasonable Efforts to resolve as promptly as practicable any objections that may be asserted with respect to such Opt-Out under any antitrust, competition or trade regulatory law, and to otherwise obtain HSR Clearance as promptly as practicable. In connection with obtaining HSR Clearance from the FTC, the DOJ or any other Governmental Authority, CRISPR and its Affiliates will not be required to, and Sirius-US and its Affiliates will not be required to, (i) sell, divest (including through a license or a reversion of licensed or assigned rights), hold separate, transfer or dispose of any assets, operations, rights, product lines, businesses or interest therein of CRISPR or any of its Affiliates or Sirius-US or any of its Affiliates (or consent to any of the foregoing actions); or (ii) litigate or otherwise formally oppose any determination (whether judicial or administrative in nature) by a Governmental Authority seeking to impose any of the restrictions referenced in clause (i) above. Neither Partnership Party may seek early termination (or early determination) of the HSR Act waiting period without the other Partnership Party’s prior written consent, or commit to or agree to stay, toll, or extend any applicable waiting period under the HSR Act, or pull or refile any filing made under the HSR Act, or enter into any timing agreement or agree not to consummate the transactions contemplated hereby for any period of time, without the other Partnership Party’s prior written consent. Each Partnership Party shall be responsible for its own costs and expenses associated with such HSR Filing, provided, however, that each Partnership Party shall pay half of any filing fees associated with such HSR Filing.

The Opt-Out Milestone Events numbered [***] as set forth in this Section 10.3.7(a) are intended to be successive; if an Opt-Out Product is not required to undergo the event associated with any such Opt-Out Milestone Event, such skipped Opt-Out Milestone Event will be deemed to have been achieved upon the achievement by such Opt-Out Product of the next successive Opt-Out Milestone Event. Payment for any such skipped Opt-Out Milestone Event that is owed in accordance with the provisions of the foregoing sentence with respect to a given Opt-Out Product will be due concurrently with the payment for the next successive Opt-Out Milestone Event by such Opt-Out Product, it being agreed that if an Opt-Out Product is not required to undergo the Opt-Out Milestone Event numbered [***], the corresponding Opt-Out Milestone Payment will be made upon the first to occur of the Opt-Out Milestone Events numbered [***]. Notwithstanding the foregoing, if prior to the Opt-Out Effective Date, the Opt-Out Milestone Events have already been accomplished by the applicable Opt-Out Product or such Opt-Out Product was not required to undergo the event associated with any such Opt-Out Milestone Event, the applicable Opt-Out Milestone Event shall be deemed to not be applicable to the Opt-Out Product and the corresponding Opt-Out Milestone Payment not due to the Opt-Out Party.

If more than one (1) Opt-Out Milestone Event is first achieved in a given Calendar Year, the Continuing Party will pay the Opt-Out Party the applicable Opt-Out Milestone Payment for each such achieved Opt-Out Milestone Event. Notwithstanding the foregoing, if prior to the Opt-Out Effective Date, the Opt-Out Milestone Events have already been accomplished by the applicable Opt-Out Product, the applicable Opt-Out Milestone Event shall be deemed to not be applicable to the Opt-Out Product and the corresponding Opt-Out Milestone Payment not due to the Opt-Out Party.

(c)

Opt-Out Milestone Cap. Notwithstanding anything to the contrary in Sections 10.3.7(a) and 10.3.7(b), if CRISPR is the Opt-Out Party and the Opt-Out Effective Date is prior to the First Commercial Sale of the applicable Opt-Out Product, Sirius-US, as the Continuing Party, shall pay CRISPR the Opt-Out Milestone Payments until the date on which the cumulative Opt-Out Milestone Payments paid by Sirius-US to CRISPR for such Opt-Out Product in the Territory are equal to or exceed [***] percent ([***]%) of CRISPR’s cumulative Development Costs incurred for such Opt-Out Product in the Territory.

All Opt-Out Royalties due for each Calendar Quarter will be due and payable within [***] days after the Continuing Party’s delivery of the applicable report.

10.3.11.

Fully Paid License. Subject to payment of all payments to Third Parties only with respect to intellectual property rights for which payments are owed to any Third Party pursuant to the Opt-Out Termination Agreement, on an Opt-Out Product-by-Opt-Out Product and country-by-country basis, upon the expiration of the Opt-Out Royalty Term for a given Opt-Out Product in a given country, the licenses granted under Section 10.3.6 with respect to such Opt-Out Product in such country shall automatically become fully paid-up, royalty-free, perpetual and irrevocable (the time period between the applicable Opt-Out Effective Date and such end date, the “Opt-Out Product Term”).

10.3.12.

Other Applicable Terms. Sections 7.4 through 7.9 shall apply with respect to the payments payable pursuant to this Section 10.3.

10.4 Consequences of Expiration or Certain Terminations of this Agreement. If this Agreement expires or is terminated by a Party in accordance with Section 10.2 (including as applicable, with respect to an Opt-Out Product subject to Section 10.3), at any time and for any reason, (a) if this Agreement expires or is terminated in its entirety, the following terms will apply with respect to any and all applicable Products (each, a “Terminated Product”), or (b) if

107

this Agreement is terminated with respect to (i) one or more Collaboration Products, but remains in effect with respect to any other Products, (ii) to one or more Licensed Products, but remains in effect with respect to any other Products or (iii) to one or more Opt-Out Products, but remains in effect with respect to any other Products, the following terms will apply to the Products with respect to which this Agreement is terminated, each of which shall be a Terminated Product, but this Agreement shall remain in full force and effect in accordance with its terms for any other Products as to which this Agreement has not been terminated:

10.4.1.

Upon termination (but not expiration) of this Agreement, the Parties shall coordinate to orderly wind down (a) the Research Program, if ongoing, and (b) Research (if applicable), Development, Manufacture and Commercialization of all Terminated Products.

10.4.2.

Upon termination (but not expiration) of this Agreement: all licenses and other rights and obligations of the Parties with respect to any Terminated Product will terminate except as provided in this Section 10.4 and in Section 10.6, and (a) [***] and (b) [***]; provided that, in the case of any sublicense agreements entered into by a Party prior to the effective date of expiration or termination, if the Sublicensee is not then in breach of its sublicense agreement with such Party, such that such Party would have the right to terminate such sublicense, such Sublicensee shall, have the right to receive a direct license from the other Party on substantially the same terms and conditions as set forth in the sublicense agreement; provided further, that (i) the scope of the license granted directly by the other Party to such direct Sublicensee shall be co-extensive with the scope of the sublicense granted by a Party to such Sublicensee and (ii) all obligations to such Sublicensee arising prior to execution of such direct license shall remain the responsibility of such Party, and the other Party shall be released from any and all liability relating to such obligations. If any Sublicensee desires to enter into such a direct license, it shall notify the other Party of such desire no later than [***] days after the effective date of termination of this Agreement. For clarity, if the Agreement is terminated in its entirety, neither Party shall have any exclusivity obligation under Section 5.11.

10.4.3.

Termination or expiration of this Agreement for any reason will be without prejudice to any rights or financial compensation that will have accrued to the benefit of a Party (for termination, with respect to the Terminated Product(s)) prior to such termination or expiration. Such termination or expiration will not relieve a Party from obligations that are expressly indicated to survive the termination or expiration of this Agreement.

10.4.4.

The Parties will return (or destroy, as directed by the other Party) all data, files, records and other materials containing or comprising the other Party’s Confidential Information with respect to the Terminated Product(s), unless such Confidential Information also relates to other Products that are not Terminated Products and except, in the event of expiration, to the extent any Confidential Information is necessary or reasonably useful for practicing any license surviving expiration. However, the Parties will be permitted to retain one copy of such data,

108

files, records, and other materials for archival and legal compliance purposes, as well as such additional copies of or any computer records or files containing such Confidential Information that have been created solely by such Party’s automatic archiving and back-up procedures, to the extent created and retained in a manner consistent with such other Party’s standard archiving and back-up procedures, but not for any other use or purpose. All Confidential Information shall continue to be subject to the terms of this Agreement for the period set forth in Article 11.

10.4.5.

If this Agreement is terminated in its entirety or all Collaboration Products are Terminated Products, then the JSC and all Committees and working groups will be dissolved as of the effective date of such termination, provided that, for any surviving provisions requiring action or decision by the JSC or any such Committee or working group or an Executive Officer, each Party will appoint representatives to act as its JSC and Committee or working group members or Executive Officer, as applicable.

10.4.6.

10.5.

Alternative Remedies in lieu of Termination.

10.5.1.

Collaboration Products. If either Partnership Party has the right to terminate this Agreement in its entirety or with respect to one or more Collaboration Products for any reason, such Partnership Party may elect, in lieu of exercising such right, as the sole monetary remedy for the applicable material breach or such other action leading to the termination right of such Partnership Party (for clarity, without affecting either Partnership Party’s (a) indemnification obligations, (b) obligation to make any payment expressly set forth in this Agreement and that became payable and was not paid to the other Partnership Party before the applicable action leading to such termination right, or (c) right to seek equitable relief, including for breach of confidentiality obligations), to keep this Agreement in effect, in which case the provisions of Section 10.3 shall apply solely with respect to the Collaboration Products to which the applicable breach or other action relates, mutatis mutandis, as if the other Partnership Party had opted out of such Collaboration Product(s) as of the date on which such other Partnership Party first committed the applicable material breach or such other action leading to the termination right of the former Party; provided, that if a Partnership Party elects its rights under this Section 10.5.1 for the other Party’s material breach, then (i) the applicable Collaboration Milestone Payments set forth in Section 7.2.6 and Opt-Out Milestone Payments set forth in Section 10.3.7, as applicable in connection with achievement of the applicable Milestone Event with respect to such Product referred to in the preceding proviso, shall be reduced by [***]; and (ii) the breaching Party’s right to participate in the JSC as well as any Committee, subcommittees or working groups established pursuant to this Agreement with respect to the Collaboration Program or the Collaboration Products will terminate.

10.5.2.

Licensed Products. If CRISPR has the right to terminate this Agreement in its entirety or with respect to one or more Licensed Products for

109

any reason (other than pursuant to Section 10.2.1), CRISPR may elect, in lieu of exercising such right, as the sole monetary remedy for the applicable material breach or such other action leading to the termination right of such Party (for clarity, without affecting CRISPR’s right to seek equitable relief, including for breach of confidentiality obligations), to keep this Agreement in effect, in which as of the date on which Sirius first committed the applicable material breach or such other action leading to the termination right of CRISPR, the amount of Milestone Payments set forth in Section 7.3.3 shall be reduced by [***] and all Royalties set forth in Section 7.3.4 shall be reduced by [***] (after giving effect to all other applicable deductions under Section 7.3.5).

10.6.

Without limiting the generality of the foregoing, to the extent that a Party provides to the other Party any Confidential Information owned by any Third Party, such other Party will handle such Confidential Information in accordance with the terms and conditions of this Article 11 applicable to a Receiving Party.

11.2.

Authorized Disclosure. Notwithstanding the foregoing provisions of Section 11.1, a Receiving Party may disclose Confidential Information belonging to the Disclosing Party to the extent such disclosure is reasonably necessary to:

11.2.1.

engage in Prosecution and Maintenance activities as contemplated by this Agreement;

11.2.2.

prosecute or defend litigation, respond to a valid order of a court of competent jurisdiction or other supra-national, federal, national, regional, state, provincial or local governmental or regulatory body of competent jurisdiction or, if in the reasonable opinion of the Receiving Party’s legal counsel, such disclosure is otherwise required by Applicable Law, including by reason of filing with securities

110

regulators; provided, however, that the Receiving Party shall first have given notice to the Disclosing Party and given the Disclosing Party a reasonable opportunity to quash such order or to obtain a protective order or confidential treatment requiring that the Confidential Information and documents that are the subject of such order or required to be disclosed be held in confidence by such court or agency or, if disclosed, be used only for the purposes for which the order was issued or such disclosure was required by Applicable Law; and provided further that the Confidential Information disclosed in response to such court or governmental order or as required by Applicable Law shall be limited to that information which is legally required to be disclosed in response to such court or governmental order or by such Applicable Law;

11.2.3.

exercise its rights and perform its obligations hereunder;

11.2.4.

11.2.5.

comply with Applicable Law.

Additionally, the Receiving Party may provide Confidential Information of the Disclosing Party, if and to the extent reasonably required in order to perform its obligations and to exploit its licenses and other rights under this Agreement, to any bona fide actual or prospective acquirers, collaborators, licensors, Sublicensees, licensees, or strategic partners and to employees, directors, agents, consultants, and advisers of any such Third Party, in each case, who are under obligations of confidentiality and non‑use with respect to such information that is no less stringent than the terms of this Section 11.2 (but of duration customary in confidentiality agreements entered into for a similar purpose).

If a Party deems it reasonably necessary to disclose Confidential Information belonging to the other Party pursuant to this Section 11.2, the Disclosing Party will to the extent possible give reasonable advance written notice of such disclosure to the other Party and take reasonable measures to ensure confidential treatment of such information.

11.3.

SEC Filings and Other Disclosures. Either Party may disclose the terms of this Agreement as permitted by Section 11.2 or (a) to the extent required to comply with Applicable Law, including the rules and regulations promulgated by the United States Securities and Exchange Commission or any equivalent governmental agency in any country; provided that such Party will reasonably consider the comments of the other Party regarding confidential treatment sought for such disclosure and (b) to its advisors (including financial advisors, attorneys and accountants) or Third Parties conducting due diligence or similar investigations, including actual or potential acquisition or collaboration partners, financing sources or investors and underwriters, in each case on a need to know basis; provided further that such disclosure is covered by terms of confidentiality similar to those set forth herein (which may include

111

professional ethical obligations) (but of duration customary in confidentiality agreements entered into for a similar purpose). For the avoidance of doubt, either Party will have the right to disclose the general status of exploitation of Products under this Agreement to such Party’s advisors (including financial advisors, attorneys and accountants) or Third Parties conducting due diligence or similar investigations, including actual or potential acquisition or collaboration partners, financing sources or investors and underwriters, in each case on a need to know basis; provided that such disclosure is covered by terms of confidentiality similar to those set forth herein (which may include professional ethical obligations) (but of duration customary in confidentiality agreements entered into for a similar purpose).

Public Announcements. Except as may be expressly permitted under Section 11.3 or Section 11.5, or as required to comply with Applicable Law (including the rules and regulations promulgated by the United States Securities and Exchange Commission or any equivalent governmental agency in any country in the Territory), neither Party will make any public announcement regarding this Agreement without the prior written approval of the other Party. Notwithstanding the foregoing, [***]. If any press release or public announcement by a Party has been reviewed or approved (as applicable) by the other Party in accordance with this Section 11.4 and made publicly available, then any subsequent press release or public statement with substantially the same content may be issued by such Party without the other Party’s review or consent (as applicable) as long as the information in such publication or presentation remains true, correct, and the most current information with respect to the subject matter set forth therein.

11.5.

Publications. During the Term, each Party will submit to the other Party (the “Non-Disclosing Party”) for review and approval any proposed academic, scientific and medical publication or public presentation related to any Collaboration Product, not to be unreasonably withheld, delayed or conditioned. In each such instance, such review and approval will be conducted for the purposes of preserving the value of the CRISPR Technology and the Sirius Technology, the rights granted to the Parties hereunder and determining whether any portion of the proposed publication or presentation containing the Non-Disclosing Party’s Confidential Information should be modified or deleted. Written copies of such proposed publication or presentation required to be submitted hereunder will be submitted to the Non-Disclosing Party no later than [***] days before submission for publication or presentation (or [***] Business Days in advance in the case of an abstract). The Non-Disclosing Party will provide its comments with respect to such publications and presentations within [***] Business Days of its receipt of such written copy (or [***] Business Days in the case of an abstract). The review period may be extended for an additional [***] days if the Non-Disclosing Party reasonably requests such extension including for the preparation and filing of patent applications. Notwithstanding anything to the contrary, the Non-Disclosing Party may require that the other Party redact the Non-Disclosing Party’s Confidential Information from any such proposed publication or presentation. CRISPR and ▇▇▇▇▇▇ will each comply with standard academic practice regarding authorship of scientific publications and recognition of contribution of other Party in any publication. Notwithstanding the foregoing, [***]. If any academic, scientific, medical or public presentation by a Party has been reviewed or approved (as applicable) by the other Party in accordance with this Section 11.5 and made publicly available, then any subsequent publication with substantially the same content may be issued by such Party without the other Party’s review or consent (as applicable) as long as the information in such publication

112

remains true, correct, and the most current information with respect to the subject matter set forth therein.

11.6.

Equitable Relief. Each Party acknowledges that its breach of this Article 11 would cause irreparable harm to the other Party, which cannot be reasonably or adequately compensated in damages in an action at law. By reasons thereof, each Party agrees that the other Party shall be entitled, in addition to any other remedies it may have under this Agreement or otherwise, to preliminary and permanent injunctive and other equitable relief to prevent or curtail any actual or threatened breach of the obligations relating to Confidential Information set forth in this Article 11 by the other Party.

or to such other address as the Party to whom written notice is to be given may have furnished to the other Party in writing in accordance herewith. In addition, each Party will deliver a courtesy copy to the other Party’s Alliance Manager concurrently with such notice. Any such written

114

notice will be deemed to have been given and received by the other Party: (a) when delivered if personally delivered; or (b) on receipt if sent by overnight courier or email.

12.5.

Amendment. Except as provided herein, including in Section 4.2.1, no amendment, modification or supplement of any provision of this Agreement will be valid or effective unless made in writing and signed by a duly authorized officer of each of Sirius and CRISPR.

12.6.

Waiver. No provision of this Agreement will be waived by any act, omission or knowledge of a Party or its agents or employees except by an instrument in writing expressly waiving such provision and signed by a duly authorized officer of the waiving Party. The waiver by either of Sirius or CRISPR of any breach of any provision hereof by the other Party will not be construed to be a waiver of any succeeding breach of such provision or a waiver of the provision itself. Except for any provision specifically referencing Sirius-US or Sirius-CY, written waiver of any provision of this Agreement by either of Sirius-US or Sirus-CY in accordance with this Section 12.6 shall be binding upon each of Sirius-US and Sirius-CY.

12.7.

Severability. If any clause or portion thereof in this Agreement is for any reason held to be invalid, illegal or unenforceable, the same will not affect any other portion of this Agreement, as it is the intent of the Parties that this Agreement will be construed in such fashion as to maintain its existence, validity and enforceability to the greatest extent possible. In any such event, this Agreement will be construed as if such clause of portion thereof had never been contained in this Agreement, and there will be deemed substituted therefor such provision as will most nearly carry out the intent of the Parties as expressed in this Agreement to the fullest extent permitted by Applicable Law.

12.8.

Descriptive Headings. The descriptive headings of this Agreement are for convenience only and will be of no force or effect in construing or interpreting any of the provisions of this Agreement.

12.9.

Performance by Affiliates. For clarity, subject to the terms and conditions of this Agreement, each Party may discharge any obligations and exercise any right hereunder through any of its Affiliates. Each Party hereby guarantees the performance by its Affiliates of such Party’s obligations under this Agreement, and shall cause its Affiliates to comply with the provisions of this Agreement in connection with such performance. 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.

12.10.

Export Control. This Agreement is made subject to any restrictions concerning the export of products or technical information from the United States or other countries that may be imposed upon or related to CRISPR or Sirius from time to time. Each Party agrees that it will not export, directly or indirectly, any technical information acquired from the other Party under this Agreement or any products using such technical information to a location or in a manner that at the time of export requires an export license or other governmental approval, without first obtaining the written consent to do so from the appropriate Governmental Authority.

115

12.11.

Governing Law; Dispute Resolution. This Agreement, and all claims arising under or in connection therewith, shall be governed by and interpreted under the substantive laws of the State of New York, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of New York or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than State of New York. The parties expressly waive and exclude the application of the Uniform Computer Information Transactions Act and/or the United Nations Convention on Contracts for the International Sale of Goods. The provisions of Schedule 1.12 shall apply with respect to Disputes (as defined therein).

12.12.

Entire Agreement. This Agreement constitutes and contains the complete, final and exclusive understanding and agreement of the Parties and cancels and supersedes any and all prior negotiations, correspondence, understandings and agreements, whether oral or written, between the Parties respecting the subject matter hereof and thereof.

12.13.

Independent Contractors. Both Parties are independent contractors under this Agreement. Nothing herein contained, other than as described in the immediately subsequent sentence, will be deemed to create an employment, agency, joint venture or partnership relationship between the Parties hereto or any of their agents or employees, or any other legal arrangement that would impose liability upon one Party for the act or failure to act of the other Party. The Parties intend that this Agreement, to the extent stated herein and solely as contemplated by the Intended Tax Treatment, in the U.S. gives rise to a partnership solely for U.S. federal (and to the extent applicable, state) income tax purposes, which shall be governed by the terms of Exhibit C and the applicable provisions herein. Neither Party will have any express or implied power to enter into any contracts or commitments or to incur any liabilities in the name of, or on behalf of, the other Party, or to bind the other Party in any respect whatsoever.

12.14.

Transparency Laws. Each Party agrees that the other Party may publicly disclose any information related to (a) any payment or transfer of value made by one Party to the other Party hereunder, or (b) any payment or transfer of value made by one Party to any Third Party or Affiliate in connection with this Agreement, in each case clauses (a) and (b), to the extent reasonably required by transparency industry regulations and transparency laws and by any means, including reporting through any government platform or system, either Party’s and its Affiliates’ websites or any other platform or system. Each Party will promptly (and in any event within [***] Business Days) provide the other Party with any such information as reasonably requested by such other Party to enable compliance with transparency industry regulations and transparency laws.

12.15.

Interpretation. Except where the context expressly requires otherwise, (a) the use of any gender herein will be deemed to encompass references to either or both genders, and the use of the singular will be deemed to include the plural (and vice versa), (b) the words “include,” “includes” and “including” will be deemed to be followed by the phrase “without limitation,” (c) the word “will” will be construed to have the same meaning and effect as the word “shall,” (d) any definition of or reference to any agreement, instrument or other document herein will be construed as referring to such agreement, instrument or other document as from time to time amended, supplemented or otherwise modified (subject to any restrictions on such amendments, supplements or modifications set forth herein), (e) any reference herein to any Person will be construed to include the Person’s successors and assigns, (f) the words “herein,” “hereof” and

116

“hereunder,” and words of similar import, will be construed to refer to this Agreement in its entirety and not to any particular provision hereof, (g) all references herein to Sections, Schedules or Exhibits will be construed to refer to Sections, Schedules or Exhibits of this Agreement, and references to this Agreement include all Schedules and Exhibits hereto, (h) provisions that require that a Party, the Parties or any committee hereunder “agree,” “consent” or “approve” or the like will require that such agreement, consent or approval be specific and in writing, whether by written agreement, letter, approved minutes, e-mail or otherwise (but excluding text messaging or instant messaging), (i) references to any specific law, rule or regulation, or article, section or other division thereof, will be deemed to include the then-current amendments thereto or any replacement or successor law, rule or regulation thereof, (j) any action or occurrence deemed to be effective as of a particular date will be deemed to be effective as of 11:59 PM ET on such date, (k) the term “or” will be interpreted in the inclusive sense commonly associated with the term “and/or” and (l) the original of this Agreement has been written in English, and the Parties waive any Applicable Law that might provide an alternative law or forum or to have this Agreement written in any language other than English.

12.16.

No Third Party Rights or Obligations. No provision of this Agreement will be deemed or construed in any way to result in the creation of any rights or obligations in any Person not a Party to this Agreement.

12.17.

Further Actions. Each Party agrees to execute, acknowledge and deliver such further instruments, and to do all such other acts, as may be necessary or appropriate in order to carry out the purposes and intent of this Agreement.

12.18.

Counterparts. This Agreement may be executed in two counterparts, each of which will be an original and both of which will constitute together the same document. Counterparts may be signed and delivered by digital transmission (e.g., .pdf), each of which will be binding when received by the applicable Party. The Parties may execute this Agreement by electronically transmitted signature and such electronically transmitted signature will be as effective as an original executed signature page.

12.19.

Cooperation. In connection with any formal or informal inquiry, investigation or request for information from a Governmental Authority relating to the transactions contemplated by this Agreement pursuant to or in connection with antitrust, competition or trade regulatory law, including in connection with any HSR Filing pursuant to Section 4.3.2 or Section 10.3.1, each Party shall use its Commercially Reasonable Efforts to (a) respond promptly to any Governmental Authority requesting information and resolve as promptly as practicable any objections that may be asserted, (b) cooperate with each other, (c) promptly keep the other Party or its counsel informed regarding any such inquiry, investigation or request, and provide copies of any communication received from or given to the Governmental Authority, relating to the transactions contemplated by this Agreement, (d) consult with each other in advance of any meeting or telephone or video conference with the Governmental Authority and, to the extent not prohibited by the Governmental Authority, give the other Party or its counsel the opportunity to attend and participate in such meetings and telephone or video conferences, and (e) permit the other Party or its counsel to review in advance, and in good faith consider the views of the other Party or its counsel concerning, any submission, filing or communication (and documents submitted therewith) intended to be given a Governmental Authority. As mutually agreed by the

117

Parties, each Party may (X) redact material required to be provided under this Section 12.19 (i) to remove references concerning valuation, (ii) as necessary to comply with contractual arrangements, and (iii) as necessary to preserve attorney-client privilege and (Y) reasonably designate any competitively sensitive material to be provided to the other under this Section 12.19 as antitrust counsel only which shall be made available only to the outside antitrust counsel of the recipient.

12.20.

Sirius Entities. Notwithstanding anything to the contrary in this Agreement:

12.20.1.

Sirius-US and Sirius-CY shall be jointly and severally liable to CRISPR for all obligations of Sirius under this Agreement;

12.20.2.

Breach or violation of any representation, warranty covenant or other obligation of Sirius under this Agreement may result from, be caused by or arise from the act or omission of any one or more of the Sirius Entities;

12.20.3.

Any particular right or interest of Sirius under this Agreement shall only be exercisable once by the specified Sirius Entity (or, if not specified, the first of Sirius-US or Sirius-CY) to exercise such right or interest hereunder on behalf of Sirius (i.e., CRISPR shall not be liable to more than one Sirius Entity with respect to any particular right or interest of ▇▇▇▇▇▇ hereunder, including any payment obligations of CRISPR hereunder); and

12.20.4.

Unless expressly provided, any consent or approval of Sirius permitted or required under this Agreement by any one of Sirius-US and Sirius-CY shall be binding upon both of Sirius-US and Sirius-CY.
