	 	(ii)	Each Party shall contribute, or cause to be contributed, to the capital of the Company the first installment of its respective initial cash capital contributions (the “Initial Contributions”). The

the Bayer Initial Contribution (the “TAF Funding Event”); provided, that in no event shall the use of any or all of the Delayed TAF Amount reduce or otherwise impact the Company’s obligation to pay the Technology Access Fee to

[...***...] Business Days of the provision of Evidence Related to Global Filings.

Contribution Agreement”). 

  

	 	(xi)	Bayer and CRISPR shall (a) take promptly all actions necessary to prepare any filings, or cause their “ultimate parent entities” as that term is defined in the Hart-Scott-Rodino Antitrust Improvement Act
of 1976 as amended (the “HSR Act”) or relevant regulations to promptly prepare any filings required of any of them under the HSR Act, which shall each be filed with the appropriate Governmental Authorities by [...***...], and
each such filing shall request the early termination of the waiting period required by the HSR Act; (b) use commercially reasonable efforts to comply at the earliest practicable date with any request for additional information received by any
of them from the Federal Trade Commission or the Antitrust Division of the Department of Justice or any other Governmental Authority with authority regarding antitrust or competition matters; and (c) reasonably cooperate with each other in
connection with the preparation and making of any such filings and the clearance of the contemplated transactions under antitrust or competition Law. [...***...] Each Party agrees to notify the other party promptly of any material
communication from a Governmental Authority regarding the contemplated transactions. Without limiting the generality of the foregoing, each Party shall provide the other Party (or its representatives) upon request copies of all correspondence and
written productions between such Party and any Governmental Authority relating to the contemplated transactions. The Parties may, as they deem advisable, designate any competitively sensitive materials provided to the other party as “outside
counsel only.” Such materials and the information contained therein shall be given only to outside counsel of the recipient and will not be disclosed by such outside counsel to employees, officers, or directors of the recipient without the
advance consent of the Party providing such materials. Subject to applicable Law, the Parties will consult and cooperate with each other in connection with any analyses, appearances, presentations, memoranda, briefs, arguments, and proposals made or
submitted to any Governmental Authority regarding the contemplated transactions by or on behalf of any Party. 

  

	 	(xii)	The Parties shall have mutually agreed to the initial business plan of the Company covering the same periods as the Initial Budget (the “Initial Business Plan”) prior to the Effective Date.

 This Agreement, together with the Company Organization Documents, the Bayer Services Agreement, the CRISPR Services
Agreement, the CRISPR IP Contribution Agreement, the Bayer IP Contribution Agreement, the Option Agreement, the Subscription Agreement, the Cross-License Agreement, the Intellectual Property Management Agreement and the Subsidiary Organization
Documents, shall be referred to herein as the “Transaction Documents.” The date on which the actions set forth in 
  

[***] = Certain confidential information contained in this document, marked by brackets, has been omitted and filed separately with the Securities and Exchange
Commission pursuant to Rule 406 of the Securities Act of 1933, as amended.

Sections 3.2(a) and (b) are complete (other than with respect to clause (ii), which shall only require the payment of the First Installment by Bayer and the CRISPR Initial
Contribution), unless otherwise waived by the Parties each acting in their sole discretion, and any applicable waiting periods (and any extensions thereof) under the HSR Act have expired or otherwise been terminated (collectively, the
“Closing Conditions”) shall be the “Effective Date”. The Effective Date shall (i) occur as promptly as practicable following the satisfaction (or waiver in accordance with the preceding sentence) of each
Closing Condition (other than the payment of the First Installment by Bayer and the CRISPR Initial Contribution, which will occur on the Effective Date), which shall occur no later than [...***...] Business Days following such satisfaction,
and (ii) occur no later than March 15, 2016 (or such date thereafter as is mutually agreed to by the Parties in writing) (the “Outside Date”). The Bayer Services Agreement, the CRISPR Services Agreement, the CRISPR IP
Contribution Agreement, the Bayer IP Contribution Agreement, the Option Agreement, the Cross-License Agreement and the Intellectual Property Management Agreement shall only become effective on the Effective Date upon the satisfaction (or waiver) of
all of the Closing Conditions. The Parties shall use reasonable best efforts to come to agreement on the forms of Transaction Documents not entered into on the date hereof as promptly as practicable, and in any event, prior to the Outside Date. If
the Effective Date does not occur on or prior to the Outside Date, each Party may terminate this Agreement at its sole discretion by delivering written notice to the other Party. As a consequence, this Agreement shall be of no further force and
effect (including any term that survives a termination of this Agreement pursuant to Section 16.1 (including Section 16.2), other than as set forth in Section 16.3). 

 

	3.3	Participation by Affiliate 

 The Parties acknowledge and agree that each Party may choose
not to hold its equity ownership interest in the Company (collectively, the “Interests”) directly, but rather indirectly through an Affiliate of such Party; provided, that in any event, such Party shall remain obligated to perform
all of its obligations under the Transaction Documents to which it (or an Affiliate) is a party; provided, further that any such transfer of Interests to any such Affiliate shall not result in tax treatment that is inconsistent with that set forth
in the Tax Appendix. The Parties acknowledge and agree that the Company may, subject to Section 7.9, form Local Operating Entities from time to time provided that such Local Operating Entity is wholly-owned (directly or indirectly) by the
Company.

subject of any collaboration with CRISPR or its Affiliates or of any collaboration partner or licensee of CRISPR or its Affiliates. 

  

	 	(e)	In no event shall a Party or the Company propose a Target, and the Parties shall ensure that neither the Company nor a Local Operating Entity Develop, Commercialize or otherwise Exploit a Target, that is a

 The first individuals named to the
Executive Team of the Company shall be the persons nominated and appointed in accordance with Sections 8.3 and 8.4. The Management Board shall determine the positions to be held by the initial Executive Team as promptly as practicable after the
date hereof, and in any event, prior to the Effective Date. 
  

	8.7	Remuneration 

 The remuneration of the members of the Executive Team, should any of them
become employees of the Company or a Local Operating Entity pursuant to Section 8.10, shall require the approval of the Management Board in the case of the CEO, but otherwise the approval of the CEO to the extent such remuneration is in
compliance with the guidelines developed as set forth in Section 8.4(a) (and otherwise, will require the approval of the Management Board). To the extent the CEO or any other member of the Executive Team is an employee of a Party who is
seconded to the Company, such Party shall fix such individual’s salary. The Company shall reimburse the seconding Party in accordance with the terms of a secondment agreement. Notwithstanding the foregoing, for so long as the CEO is a
Conflicted CEO (including the initial CEO), any such decision with respect to the officers shall be made by the Management Board. In addition, the initial CEO of the Company shall not receive any remuneration for serving in such capacity (or his
resignation) without the prior approval of the Management Board. 
  

	8.8	Executive Team Reports to the Management Board 

 The Executive Team, through the CEO,
shall report to, and shall at all times be subject to the direction of, the Management Board. Without limiting the generality of the foregoing, the Executive Team shall prepare and submit to the Management Board and the Members quarterly reports, in
reasonable detail, on the operations of the Company and all applicable Local Operating Entities, as soon as available and, in any event, within thirty (30) days after the end of each calendar quarter (including the last). Such reports shall
include quarterly consolidated financial statements (including an unaudited profit and loss statement, balance sheet and cash flow statement) of the Company and each Local Operating Entity for the applicable quarter and the fiscal year-to-date
period prepared in accordance with U.S. GAAP and IFRS, setting forth in each case in comparative form the actual, budgeted and prior year figures for the corresponding quarter and the corresponding fiscal year-to-date period. 

 

	8.9	Human Resources 

  

	 	(a)	Transfer of Employees. The initial conditions of service of Company and any Local Operating Entity personnel are to be determined by the Management Board. If at any time the Company or a Local Operating Entity
desires to accept transfers of employees from the Parties or their Affiliates to become Company or Local Operating Entity employees, the Parties intend that, as soon as practical thereafter, the human resources policies of the Company and each Local
Operating Entity will be determined by the Management Board.

	 	(b)	Employment Liabilities. If at any time the Company or a Local Operating Entity desires to accept transfers of employees from the Parties or their Affiliates, the Parties or their Affiliates will calculate the
monetary value of all long term personnel liabilities which are to be transferred to the Company or the Local Operating Entity as a result of negotiations between the Parties or their Affiliates and the employees. These may include such liabilities
as pension fund, long service awards and leave, share options, loan guarantees, medical aid and employee savings plans, and such other liabilities as may be agreed to by the Parties or their Affiliates after full disclosure and completion of due
diligence by each Party or its Affiliates. All personnel liabilities not transferred to the Company or a Local Operating Entity will remain the responsibility of the Party or its Affiliates. Notwithstanding anything in this Section 8.9 to the
contrary, the approval of the Management Board shall be required to assume employment liabilities described herein. 

  

	 	(c)	Secondments. The Parties agree that it would be in the best interests of the Parties, the Company and each Local Operating Entity to allow the secondment of the Parties’ or its Affiliates’ employees
(the “Seconded Employees”) with the requisite skills and availability to the Company or a Local Operating Entity after the Effective Date in accordance with policies to be set forth by the applicable Management Board. The Parties
will identify and allow the secondment of personnel to the Company or a Local Operating Entity in accordance with a secondment agreement to be agreed. The CEO shall have the authority to terminate the secondment agreement of any seconded employees
without the consent of the Management Board or the Parties. 

  

	 	(d)	IP Matters. As between the (i) Company and the Local Operating Entities, on the one hand, and (ii) CRISPR or Bayer (and their respective Affiliates), on the other hand (each a “Primary
Employer”), the Company and each Primary Employer agree that (i) any Seconded Employee’s works of authorship, discoveries, inventions and innovations resulting from the services performed by such Seconded Employees for the Company
or a Local Operating Entity, or (ii) any proposals, research, records, reports, recommendations, manuals, findings, evaluations, forms, reviews, information, data, computer programs and software originated or created by any Seconded Employee
for the Company or a Local Operating Entity or in the performance of such services (such items being hereinafter referred to collectively and severally as “Work Product”), in each case which is an original work of authorship,
including but not limited to any computer program or software, is a “work made for hire” within the meaning of 17 United States Code Section 101 in that it is a work that has been specially ordered or commissioned by the Company or
such Local Operating Entity for use as a contribution to a collective work, as part of an audiovisual work, as a translation, as a supplementary work, as a compilation and/or as an instructional text. To the extent any Work Product is not a
“work made for hire,” each Primary Employer

hereby agrees to take all action to assign, and to have the Seconded Employees assign, to the Company or such Local Operating Entity all right title and interest in and to such Work Product,
including all intellectual property rights therein or based thereon. Notwithstanding the foregoing or anything else herein to the contrary, the rights and obligations under this Section 8.9(d) and the final allocation of ownership with respect
to any Work Product (including all intellectual property rights therein) shall be allocated in accordance with, and remain subject to, in all cases the terms and conditions of the Intellectual Property Management Agreement. 

 

	8.10	Local Operating Entities 

 The provisions in Sections 8.1 through 8.8 shall apply
mutatis mutandis to each Local Operating Entity to the extent permitted by applicable Law and not inconsistent with the terms of the Tax Appendix. 
  

	8.11	Business Plans; Budgets 

  

	 	(a)	The initial operational budget (the “Initial Budget”) and the initial investment budget (the “Initial Investment Budget”), in each case for a period from the date hereof through
December 31, 2017, shall be attached hereto as Schedule 8.11 to this Agreement. The Initial Business Plan shall be attached to Schedule 8.11 on or prior to the Effective Date. The Parties acknowledge and agree that the
Initial Business Plan, the Initial Budget and the Initial Investment Budget may, upon the approval of the Management Board as set forth in Section 7.9, be amended as appropriate. 

 

	 	(b)	On or about [...***...] of each fiscal year starting in 2016, the Management Board shall begin discussions regarding the 24-month operational budget for the 24-month period starting on January 1st of the next fiscal year (each, a “Rolling Budget”), an investment budget for the same period (each, a “Rolling Investment Budget”) and a business plan for the same
period (each, a “Rolling Business Plan”). Each Party shall cause its designees on the Management Board to use reasonable best efforts to obtain the required approval of the Management Board of such Rolling Budget, such Rolling
Investment Budget and such Rolling Business Plan until such approval is obtained. If, pursuant to Section 7.9, the Management Board fails to approve an updated Rolling Business Plan, Rolling Budget and Rolling Investment Budget for a fiscal
year by [...***...] of the prior fiscal year, then the matter shall be escalated in accordance with the procedures set forth in Section 12.1. Once such Rolling Business Plan, such Rolling Budget and such Rolling Investment Budget have
been approved, CRISPR designated members of the Management Board shall have final approval with respect to funds allocations to Targets in the CRISPR Fields and the Bayer designated members of the Management Board shall have final approval with
respect to funds allocations to Targets in the Bayer Fields.

 20 

	 	(c)	Once a Rolling Budget and each Rolling Business Plan for any fiscal year is approved pursuant to Section 7.9 by the Management Board, the Executive Team shall manage the Company and each Local Operating Entity
according to industry best practices in a commercially reasonable manner to endeavor to achieve the Rolling Budget and each Rolling Business Plan for such fiscal year. 

 

	 	(d)	Each Rolling Budget shall include, for informational and planning purposes only, a good faith estimate of the costs required for the Dissolution. Such estimate shall be as detailed as the Management Board determines is
appropriate following reasonable analysis. Such costs shall include costs such as lease termination, employee severance and termination and contract termination costs. For the avoidance of doubt, such costs shall not be funded unless and until they
are required to be funded in connection with the Dissolution. 

  

	 	(e)	If the applicable Rolling Investment Budget is not approved in accordance with Section 8.11(b) prior to [...***...] of the fiscal year immediately preceding the period covered by such Rolling Investment
Budget, the amount allocated for investment activities for the first fiscal year covered by such Rolling Investment Budget shall be deemed to equal the amount allocated in the Rolling Investment Budget for the immediately preceding fiscal year and
for the second year covered by such Rolling Investment Budget shall be deemed to equal the amount for such first fiscal year; provided, that, if such Rolling Investment Budget is later approved in accordance with Section 8.11(b), the allocated
amounts shall thereafter equal the respective amounts approved for investments in such Rolling Investment Budget. 

ARTICLE 9 - FUNDING 
  

	9.1	Committed Cash Contributions 

  

	 	(a)	Committed Cash Contributions (Capital). As of the date hereof, the aggregate committed cash contributions of each Party to the capital of the Company (which is comprised of its Initial Contribution and its
Additional Contribution) are as follows: (i) with respect to CRISPR, US $100,000; and (ii) with respect to Bayer, US $300,000,000 (the “Bayer Commitment Amount”). The Bayer Commitment Amount is to be understood as paid-in
capital with deferred payment terms. Each cash contribution to the capital of the Company shall be payable in immediately available funds (in US dollars) pursuant to wire transfer instructions provided to the paying Party prior to the contribution
date. In the event that any Party does not make its Initial Contribution set forth on Schedule 3.2(b)(ii) or any additional contribution (including any Additional Contribution) when due, such Party shall be in material breach of this
Agreement and the other Party may seek any remedy provided for in this Agreement, which provides that such Party shall first have the ability to cure the breach as set forth in Section 19.1(a); thereafter, such other Party may terminate this
Agreement in accordance with Section 16.1(c) and/or pursue any other remedy provided for herein. The Company shall provide Bayer and CRISPR, as the case may be, a written invoice including due date for any capital contribution required to be
made to the Company hereunder in advance of the date of such contribution.

 21 

	 	(b)	Initial Contributions. Upon receipt of the first installment of the Initial Contributions by the Company from each Party and the execution by CRISPR of the CRISPR IP Contribution Agreement, each Party shall have
a 50% Interest in the Company and 50% of the voting rights therein. The second installment of the Initial Contribution by Bayer shall occur within [...***...] of the provision of Evidence Related to Global Filings. 

 

	 	(c)	Additional Contributions 

  

	 	(i)	“Additional Contribution” shall mean an additional cash contribution by a Party to the capital of the Company following its Initial Contribution. As of the date hereof, the aggregate amount of the
Additional Contributions to be made by Bayer pursuant to this Agreement shall equal, and not exceed without its consent, the Bayer Commitment Amount minus its Initial Contribution (the “Bayer Additional Contribution Cap”). As of the
date hereof, CRISPR shall not be responsible for any Additional Contribution. Each Additional Contribution made to the Company shall not alter Bayer’s 50% Interest in the Company or its 50% voting rights in meetings of the Members. For the
avoidance of doubt, in no event shall Bayer be required to make an Additional Contribution without its consent (including pursuant to Section 9.1(d)) until CRISPR provides the Evidence Related to Global Filings; provided, that, if any amounts
would otherwise have become due under clause (ii) of this Section 9.1(c) prior to such provision of the Evidence Related to Global Filings, any such Additional Contribution(s) shall be made in conjunction with the second installment of the
Initial Contribution. 

  

	 	(ii)	Bayer shall make an Additional Contribution following the occurrence of any of the following triggers, in an amount calculated and otherwise payable in accordance with the following: 

 

	 	(1)	Budget Funding. The Parties agree that the Initial Contributions are intended to fund the Initial Budget. Within [...***...] following the approval of each Rolling Budget in accordance with
Section 8.11(b), written notice (with respect to such Rolling Budget, a “Budgetary Funding Notice”) shall be provided by the CEO to the Parties which details the following: (x) the cash requirements of the Company and the
Local Operating Entities based on such Rolling Budget (with respect to such Rolling Budget, the “Cash Requirements”); (y) the expected available cash of the Company and the Local Operating Entities as of January 1st of the first fiscal year covered by such Rolling Budget (with respect to such Rolling Budget, the “Expected Cash”); and (z) the difference between such Cash Requirements and
such Expected

Cash (with respect to such Rolling Budget, the “Additional Budgetary Funding Amount”). Bayer shall make an Additional Contribution equal to the Additional Budgetary Funding
Amount as promptly as practicable (and in any event within [...***...]) of its receipt of the Budgetary Funding Notice. Notwithstanding the foregoing, if the applicable Rolling Budget is not approved in accordance with Section 8.11(b)
prior to [...***...] of the fiscal year immediately preceding the period covered by such Rolling Budget, the Cash Requirements for such Rolling Budget shall be deemed to equal [...***...] of the Cash Requirements for the immediately
preceding fiscal year (the “Deemed Cash Requirements”) and the CEO shall deliver the Budgetary Funding Notice assuming the Deemed Cash Requirements; provided, that, if such Rolling Budget is later approved and the actual Cash
Requirements are greater than the Deemed Cash Requirements, the CEO shall submit another Budgetary Funding Notice to the Parties as promptly as practicable following such approval with an Additional Budgetary Funding Amount equal to the actual Cash
Requirements minus the Deemed Cash Requirements. 

  

	 	(2)	Acquisition Transaction Funding. From time to time, the CEO may provide written notice (a “CEO Acquisition Notice”) to the Parties of a proposed acquisition of tangible and/or intangible assets
(including Intellectual Property) directly relating to or that would be complementary to the Business (an “Acquisition Transaction”), which may take the form of a license of such assets to the Company and/or a Local Operating Entity
or the purchase of assets or an entity/entities, that are covered by the Initial Investment Budget or the Rolling Investment Budget, as applicable, and not explicitly covered by the Initial Budget or the Rolling Budget, as applicable. Such CEO
Acquisition Notice shall detail the cash contribution amount required to effectuate such Acquisition Transaction (the “Acquisition Transaction Funding Amount”), a summary of the assets to be acquired and the owners thereof and the
date that funds would be required to consummate such Acquisition Transaction (the “Acquisition Transaction Funding Date”); provided, that if additional consideration (an “Acquisition Transaction Additional Funding
Amount”) is required to be paid by the Company or a Local Operating Entity for any such asset after the applicable Acquisition Transaction Funding Date (an “Acquisition Transaction Additional Payment”) that (A) would
require [...***...] or (B) [...***...], the prior written consent of the Parties shall be required for such Acquisition Transaction, which consent shall not be unreasonably withheld, conditioned or delayed. Bayer shall make an
Additional Contribution equal to (i) the Acquisition Transaction Funding Amount on or prior to the Acquisition Transaction Funding Date (provided, that if the

Acquisition Transaction Funding Date is less than [...***...] Business Days after Bayer’s receipt of the CEO Acquisition Notice, the Company or a Local Operating Entity may fund the
Acquisition Transaction with available cash and Bayer shall fund the Acquisition Transaction Funding Amount to the Company as promptly as practicable (and in any event within [...***...] Business Days of its receipt of such CEO Acquisition
Notice)) and (ii) the Acquisition Transaction Additional Funding Amount as promptly as practicable (and in any event within [...***...] Business Days of its receipt of written notice from the CEO of the applicable Acquisition Transaction
Additional Payment). Without the prior written consent of the Parties, in no event shall Bayer be required to make Additional Contributions pursuant to this Section 9.1(c)(ii)(2) in excess of an amount equal to [...***...] of the amount
set forth in the Initial Investment Budget or the Rolling Investment Budget, as applicable (the “Investment Cap”). 

  

	 	(3)	Management Board Approved Funding. The Management Board may approve additional funding of the Company from time to time in accordance with Article 7. The Company shall provide the Parties with written notice
of such approval as promptly as practicable following such approval. Bayer shall make an Additional Contribution equal to the amount so approved by the Management Board as promptly as practicable (and in any event within ten (10) Business Days)
of its receipt of such notice. 

  

	 	(iii)	Provided that this Agreement is not terminated in accordance with Section 16.1 by [...***...] (the “Funding Outside Date”), Bayer shall make an Additional Contribution on the Funding Outside
Date equal to the Bayer Additional Contribution Cap minus the aggregate amount of all Additional Contributions made by Bayer prior to the Funding Outside Date. 

  

	 	(d)	Acquisition Transactions Prior to [...***...] 

  

	 	(i)	At any time prior to [...***...], if the Management Board determines that it is advisable for the Company or a Local Operating Entity to acquire, through license or otherwise, any Intellectual Property or
technology from a Third Party, the CEO (or during the tenure of the initial CEO, any member of the Management Board) may provide a CEO Acquisition Notice to the Company and the Parties with respect to such Intellectual Property or technology;
provided, that in no event shall the amount required to fund such acquisition (together with other amounts funded under this Section 9.1(d)(i)) exceed the [...***...]. Upon its receipt of such CEO Acquisition Notice, [...***...]
(A) shall have the option, but not the obligation, to [...***...] and (B) agrees to promptly present such acquisition to the [...***...].[...***...] shall provide the Company and CRISPR written notice of its decision of

	 	(2)	If [...***...] does not agree to [...***...],[...***...] shall have the option, but not the obligation, to [...***...] the Company the required amount on customary terms [...***...]. All
[...***...] would become [...***...] within [...***...] Business Days of [...***...]. The [...***...] shall be [...***...] as an [...***...] as contemplated by the last sentence of [...***...].

  

	 	(ii)	For the avoidance of doubt, following [...***...], this Section 9.1(d) shall no longer apply and the other provisions of Section 9.1 shall control all [...***...]. 

 

	9.2	Future Funding 

 Except as otherwise provided in this Article 9 and
Section 6.2, all financing beyond the capital contributions set forth in Section 9.1 shall be approved by the Management Board in accordance with Section 7.9. 
  

	9.3	Further Capital Contributions 

 No Party shall be required to provide any cash
contributions to the capital of the Company without its consent other than those forming part of the Initial Contributions and the Additional Contributions as well as funding approved in accordance with Sections 9.2, 9.5 and 16.2(b). 

 

	9.4	Total Capital of the Company 

 For the avoidance of doubt, the total capital of the
Company consists of the total cash contributions of the Parties, i.e. the Initial Contributions and the Additional Contributions, as well as the rights licensed to the Company under the CRISPR IP Contribution Agreement. 

 

	9.5	Procedure for Excess Funding 

  

	 	(a)	If, at any time after Bayer has provided to the Company its Initial Contribution and all Additional Contributions required hereunder (the “Initial Period”), the Company’s and the Local Operating
Entities’ operating income and cash on hand is expected to be insufficient to fund its working capital requirements for the next [...***...] period, as certified by the CEO to each Member in writing, the Management Board shall, within
[...***...] days following the CEO’s certification, discuss in good faith, and in accordance with the principle set forth in Section 9.1, the most appropriate methods of obtaining financing for the Company and the Local Operating
Entities.

the Company within [...***...] following the CEO’s certification or (ii) the Company cannot obtain any financing approved by the Management Board in accordance with Section 7.9 to fund its working capital requirements within
[...***...] following the CEO’s certification, then the matter shall be escalated in accordance with the procedures set forth in Section 12.1. If (x) a method of obtaining financing for the Company is not determined within
[...***...] following such escalation or (y) the Company cannot obtain any financing approved by the Management Board in accordance with Section 7.9 to fund its working capital requirements within [...***...] following such
escalation, either Party shall have the right to terminate this Agreement pursuant to Section 16.1(g) from such earlier date until the CEO provides each Member a further certification in writing that the Company’s and the Local Operating
Entities’ operating income and cash on hand (including any cash receiving in connection with financings approved by the Management Board in accordance with Section 7.9) is expected to be sufficient to fund its working capital requirements
for the next [...***...] (such period during with a Party may terminate this Agreement pursuant to Section 16.1(g), the “Funding Shortfall Termination Period”). 

 

	9.6	Allocation of Cash Contributions to the Capital of the Company 

 Unless otherwise
approved by the Management Board in accordance with Section 7.9 or as expressly set forth in the Initial Budget or a Rolling Budget, the funding of the Company shall be allocated [...***...] to the Development of Products and technology

Bayer and CRISPR shall nominate Targets in accordance with the procedures set forth in Section 7.13 in connection with developing the Initial Business Plan and the Rolling Business Plan, as applicable; provided, further, that in each Rolling

ARTICLE 17 - CONFIDENTIALITY AND PRESS RELEASES 
  

	17.1	Confidentiality 

 Each Party shall, and shall cause its Affiliates to, keep confidential
any oral or written, tangible or intangible, proprietary or confidential information (“Information”) of the other Party or its Affiliates, the Company or a Local Operating Entity, furnished to it by the other Party, its Affiliates
or their directors, officers, employees, representatives or agents, or by the Company or a Local Operating Entity or its directors, officers, employees, representatives or agents, or obtained by it in connection with the transactions contemplated by
this Agreement or any other Transaction Document. The term “Information” shall be deemed to include those portions of any notes, analyses, compilations, studies, interpretations, memoranda or other documents (regardless of the form
thereof) prepared by the receiving Party or its Affiliates or its or their directors, officers, employees, representatives or agents which contain, reflect or are based upon, in whole or in part, any Information of the disclosing Party or its
Affiliates, the Company or a Local Operating Entity. In addition, such Party and its Affiliates shall not use such Information except in connection with the transactions or the performance of the obligations of such Party or such Affiliate
contemplated hereby or any other Transaction Document, the exercise of any rights hereunder or thereunder or as expressly provided for herein or therein. Neither Party or its Affiliates will disclose the Information of the other Party or its
Affiliates, the Company or a Local Operating Entity to its Affiliates or its or their directors, officers, employees, representatives or agents unless such Person has a reasonable need to know such Information in connection with the transactions or
the performance of the obligations of such Party or such Affiliates contemplated hereby or any other Transaction Document, the exercise of any rights hereunder or thereunder or as 

 
 [***] = Certain confidential information contained in this document, marked by brackets,
has been omitted and filed separately with the Securities and Exchange Commission pursuant to Rule 406 of the Securities Act of 1933, as amended. 

  
 34 

 
expressly provided for herein or therein. Neither Party or its Affiliates shall release or disclose such Information to any other Person, except those among its auditors, attorneys, financial
advisors, bankers and consultants having a need to know such Information in connection with the transactions or the performance of the obligations of such Party or such Affiliate contemplated hereby or any other Transaction Document, the exercise of
any rights hereunder or thereunder, as required to comply with applicable Law or reporting requirements, or as expressly provided for herein or therein, or to actual or potential acquirers, collaborators, licensees, sub-licensees investment bankers,
investors or lenders. Each Person receiving any such Information shall be subject to customary confidentiality obligations prior to such Person’s receipt of such Information and such Party shall be primarily liable and responsible for any
breach of this Section 17.1 as if such Person was a party hereto. In addition, each Party and its Affiliates are permitted to disclose such Information to the extent such disclosure is to a Governmental Authority as reasonably necessary in
filing or prosecuting Patent, copyright and trademark applications, prosecuting or defending litigation related to this Agreement or any other Transaction Document, complying with applicable governmental regulations with respect to performance under
this Agreement or any other Transaction Document or otherwise required by applicable Law. If a Party or any of its Affiliates (the “Compelled Party”) is requested to disclose any Information by any governmental or regulatory
authority (including stock exchange rules, GAAP or IFRS), the Compelled Party will promptly notify the other Party or the Company, as applicable (the “Affected Party”), to permit it to seek a protective order or take other action
that the Affected Party in its discretion deems appropriate, and the Compelled Party will cooperate in any such efforts to obtain a protective order or other reasonable assurance that confidential treatment will be accorded such Information. If, in
the absence of a protective order, the Compelled Party is compelled as a matter of Law to disclose any such Information in any proceeding or pursuant to legal process (as advised by its outside legal counsel), the Compelled Party may disclose to the
Person compelling disclosure only the part of such Information as is required by Law to be disclosed (in which case, prior to such disclosure, the Compelled Party will advise and consult with the Affected Party and its counsel as to such disclosure
and the nature and wording of such disclosure) and the Compelled Party will use its reasonable best efforts to obtain confidential treatment therefor. The confidentiality obligations contained in this Section 17.1 do not apply to Information
that can be shown by such Party to have been (i) previously known by the Party or its Affiliates to which it was furnished prior to the date hereof (and not under a confidentiality obligation), (ii) generally available to the public
through no fault or breach of such Party or its Affiliates, (iii) later lawfully acquired from other sources (not under a confidentiality obligation) by the Party or its Affiliates to which it was furnished or (iv) independently developed
by a Party or its Affiliates or its or their directors, officers, employees, representatives or agents without the use or reference to any Information of the other Party, or its Affiliates, the Company or any Local Operating Entity. For the
avoidance of doubt, in no event shall any information provided by a Party or its Affiliates (or one of its directors, officers, employees, representatives or agents) to the Company or a Local Operating Entity be considered Information of the Company
or a Local Operating Entity with respect to such Party or its Affiliates under this Section 17.1. Following a termination of this Agreement, such confidentiality obligations and use restrictions shall 

 
 [***] = Certain confidential information contained in this document, marked by brackets,

 35 

 be maintained, subject to the exceptions set forth above, and all Information of the other Party
and its Affiliates (including all copies thereof) shall be returned (or, at the other Party’s instructions, destroyed, with certification of the same) to the Party that the other Party and its Affiliates shall be permitted to retain such
Information (i) to the extent necessary for purposes of performing any continuing obligations or exercising any ongoing rights hereunder or under a Transaction Document and, in any event, one copy of such Information retained by the other
Party’s legal department for its records (provided that for so long as such Information is so retained, such Information shall be subject to the confidentiality obligations and restrictions on use as set forth herein), and (ii) any
computer records or files containing such Information that have been created solely by such Party’s or its Affiliates’ automatic archiving and back-up procedures, to the extent created and retained in a manner consistent with such
Party’s standard archiving and back-up procedures, but not for any other use or purposes. 
  

	17.2	Duration of Confidentiality 

 The provisions of Section 17.1 shall continue to apply
with respect to each Party and its Affiliates until the date which is [...***...] following the termination of this Agreement. 
  

	17.3	Press Releases and Other Public Disclosures 

 Neither Party shall issue any press release
or otherwise make any public statement with respect to this Agreement or the other Transaction Documents without the prior written consent of the other Party, except in case of public announcements required under the rules of any stock exchange on
which the equity interests of a Party or its Affiliates (or any successor entity) are listed or any applicable Law or governmental requirement. Notwithstanding anything to the contrary in this Article 17, a Party (or its Affiliates) may
disclose this Agreement and the other Transaction Documents (and a summary thereof) as well as the financial statements of the Company and Local Operating Entities and financial data derived therefrom, in securities filings with the U.S. Securities
and Exchange Commission or an equivalent foreign agency to the extent required by applicable Law. In such event, the Party seeking such disclosure shall prepare such summary and a proposed redacted version of this Agreement and/or the other
Transaction Documents to request confidential treatment for such agreements, and the other Party may promptly (and in any event, no less than [...***...] Business Days after receipt of such summary and proposed redactions) provide its
comments. The Party seeking such disclosure shall reasonably consider any comments thereto provided by the other Party within such [...***...] Business Day period. The Parties have agreed to issue a joint press release or separate press
releases announcing this Agreement and the transactions contemplated hereby, to be issued by the Parties at a mutually agreed date and time, in the form(s) to be agreed by the Parties in their reasonable discretion. 

 

	17.4	Publications 

 During the Term, each Party will submit to the Company for review and
approval any proposed academic, scientific and medical publication or public presentation related to any Licensed Agent or Product or any activities conducted under the Transaction 

 
 [***] = Certain confidential information contained in this document, marked by brackets,
has been omitted and filed separately with the Securities and Exchange Commission pursuant to Rule 406 of the Securities Act of 1933, as amended. 

  
 36 

 
Documents, in each case, to the extent it includes Information of the Company or a Local Operating Entity. In each such instance, such review and approval will be conducted for the purposes of
preserving the value of the CRISPR Contributed Technology, the Bayer Licensed Technology and the Company Program Technology, the rights granted under the Transaction Documents and determining whether any portion of the proposed publication or
presentation containing the Company’s Information should be modified or deleted. Written copies of such proposed publication or presentation required to be submitted hereunder will be submitted to the Company no later than [...***...]
before submission for publication or presentation (or [...***...] in advance in the case of an abstract). The Company will provide its comments with respect to such publications and presentations within [...***...] of its receipt of such
written copy (or [...***...] in the case of an abstract). The review period may be extended for an additional [...***...] if the Company reasonably requests such extension including for the preparation and filing of patent applications.
Notwithstanding anything to the contrary, the Company may require, in its reasonable discretion, that the requesting Party redact the Company’s Information from any such proposed publication or presentation. The Parties will each comply with
standard academic practice regarding authorship of scientific publications and recognition of contribution of other parties in any publication. Notwithstanding the foregoing, a Party’s obligation to submit any publication to the Company for
review and approval under this Section 17.4 will not apply to any publication made by a Party with respect to Licensed Products for which such Party has completed an Opt-In Transaction that does not contain Information or disclose any
non-public information of the Company, a Local Operating Entity or the other Party (other than, for the avoidance of doubt, Information relating to the Licensed Products for which such Opt-In Transaction relates); provided, that where reasonably
possible, such Party will provide the Company with an advance copy of such publication if such publication is reasonably likely to have a material adverse effect on the value of CRISPR Contributed Technology, Bayer Licensed Technology or the Company
Program Technology. For clarity, neither Bayer nor CRISPR are obligated hereunder to submit proposed publications to the other Parties for all proposed publications relating to work conducted outside of the scope of this Agreement and the other
Transaction Documents. 
  

	17.5	Attorney-Client Privilege 

 Neither Party is waiving, nor will be deemed to have waived
or diminished, any of its attorney work product protections, attorney-client privileges or similar protections and privileges as a result of disclosing information pursuant to this Agreement, or any of its Information (including Information related
to pending or threatened litigation) to the receiving Party, regardless of whether the disclosing Party has asserted, or is or may be entitled to assert, such privileges and protections. The Parties: (a) share a common legal and commercial
interest in such disclosure that is subject to such privileges and protections; (b) are or may become joint defendants in proceedings to which the information covered by such protections and privileges relates; (c) intend that such
privileges and protections remain intact should either Party become subject to any actual or threatened proceeding to which the disclosing Party’s Information covered by such protections and privileges relates; and (d) intend that after
the Effective Date both the receiving Party and the disclosing Party will have the right to assert such protections and privileges.

 This Agreement supersedes the Confidentiality Agreement entered into
between Bayer AG and CRISPR dated [...***...]. All confidential information exchanged between the Parties under such agreement will be subject to the terms of this Agreement. 

ARTICLE 18 – RESERVED 

ARTICLE 19 – BREACH 

 

	19.1	Breach 

  

	 	(a)	If a Party alleges that the other Party (the “Breaching Party”) has failed to perform any of its material covenants, obligations or agreements provided for in this Agreement, including, without
limitation, its financial obligations or its obligations concerning the Transfer of Interests, it shall provide written notice of such alleged failure to the Breaching Party. Subject to the proviso set forth below, the Breaching Party shall have
[...***...] following such written notice (a “Cure Period”) to remedy such failure if such Breach is curable and if the non-Breaching Party will not be materially prejudiced thereby, and if it fails to remedy such failure
within such Cure Period, the Breaching Party shall be in breach of this Agreement (“Breach”); provided that (i) no notice shall be required and no cure period to remedy a Breach shall apply to failure to make the first
installment of the Initial Contribution by Bayer or the Initial Contribution by CRISPR or the failure of CRISPR to execute and deliver the CRISPR IP Contribution Agreement. However, there shall be a notice requirement and a [...***...] to
remedy failure of Bayer to make the second installment of the Initial Contribution and the Additional Contribution when due. 

  

	 	(b)	Upon Breach by one Party, the non-Breaching Party shall have the right to seek all remedies available hereunder (including the termination rights set forth in Section 16.1 if such Breach would trigger any such
right), in law or in equity; provided, however, that nothing contained in this Section shall limit the non-Breaching Party’s ability to enjoin any Breach of the provisions of this Agreement regarding Transfer of Interests and no
[...***...] remedy period shall apply in such instance. 

  

	 	(c)	In addition to any other remedies set forth in this Agreement, the remedies for any Breach shall include damages and injunctive relief, including specific performance. Unless provided for herein, the rights and remedies
provided in this Agreement are cumulative and are not exclusive of any rights or remedies that either Party may otherwise have at law or in equity.

 ARTICLE 20 - DISPUTE RESOLUTION

thereof shall first be referred to the head of Bayer AG’s Head of R&D and CRISPR’s Chief Executive Officer for resolution. If these individuals are unable to agree upon a resolution within [...***...] after referral of the matter
to them (a “Resolution Period”), then either Party may pursue any available remedy hereunder, at law or in equity. 
  

	20.2	Attorneys’ Fees 

 If any action at law or in equity (including, arbitration) is

necessary disbursements in addition to any other relief to which such Party may be entitled.

Association in accordance with the then current Commercial Rules of the American Arbitration Association including the Procedures for Large, Complex Commercial Disputes (“AAA Rules”), except that any such arbitration must be
conducted in accordance with the remainder of this Section 20.3. For the avoidance of doubt, if there is a dispute as to the occurrence of any of the events in Section 16.1(b), (d), (e), (f) or (h) and a Party is seeking remedies
other than to terminate this Agreement, then such dispute shall not be required to be settled by arbitration as contemplated by this Section 20.3. 

  

	 	(b)	Number and Selection of Arbitrators. The number of arbitrators shall be [...***...], who shall be selected as follows: each of Bayer, on the one hand, and CRISPR on the other hand, shall choose one
(1) arbitrator within [...***...] of either initiating or receiving notice of an arbitration (as the case may be), and those Party-appointed arbitrators shall unanimously select one (1) chairman arbitrator within [...***...] of

	 	(f)	Period for Arbitration. 

  

	 	(i)	The arbitration shall be completed no later than [...***...] after the selection of the chairman arbitrator, unless the chairman arbitrator determines, at the request of any Party or on his or her own initiative,

otherwise. References to sums of money are expressed in lawful currency of the United States (U.S. dollars), unless the Parties otherwise agree in writing to use a different currency.

and, in any event, one copy of such Information retained by the other Party’s legal department for its records (provided that for so long as such Information is so retained, such Information shall be subject to the confidentiality obligations
and restrictions on use as set forth herein), and (ii) any computer records or files containing such Information that have been created solely by such Party’s or its Affiliates’ automatic archiving and back-up procedures, to the extent

presentation. The Parties will each comply with standard academic practice regarding authorship of scientific publications and recognition of contribution of other parties in any
publication. Notwithstanding the foregoing, a Party’s obligation to submit any publication to the Reviewing Party for review and approval under this Section 5.4 will not apply to any publication made by a Party with respect to Licensed
Products for which such Party has completed an Opt-In Transaction that does not contain Information or disclose any non-public information of the Reviewing Party (other than, for the avoidance of doubt, Information relating to the Licensed Products
for which such Opt-In Transaction relates); provided, that where reasonably possible, such Party will provide the Reviewing Party with an advance copy of such publication if such publication is reasonably likely to have a material adverse effect on
the value of CRISPR Contributed Technology or Bayer Background Technology. For clarity, neither Bayer nor CRISPR are obligated hereunder to submit proposed publications to the other Parties for all proposed publications relating to work
conducted outside of the scope of this Agreement and the other Transaction Documents. 

  

	 	5.5.	Attorney-Client Privilege. Neither Party is waiving, nor will be deemed to have waived or diminished, any of its attorney work product protections, attorney client privileges or similar protections and
privileges as a result of disclosing information pursuant to this Agreement, or any of its Information (including Information related to pending or threatened litigation) to the receiving Party, regardless of whether the disclosing Party has
asserted, or is or may be entitled to assert, such privileges and protections. The Parties: (a) share a common legal and commercial interest in such disclosure that is subject to such privileges and protections; (b) are or may become joint
defendants in proceedings to which the information covered by such protections and privileges relates; (c) intend that such privileges and protections remain intact should either Party become subject to any actual or threatened proceeding to which
the disclosing Party’s Information covered by such protections and privileges relates; and (d) intend that after the Effective Date both the receiving Party and the disclosing Party will have the right to assert such protections and privileges.

	 	6.1.	Referral to Heads of Businesses. Unless otherwise specified in this Agreement, the Parties hereby agree that to the extent reasonably practicable and would not materially prejudice a Party,
controversies or claims arising out of or relating to this Agreement or the interpretation, performance, breach, termination or validity thereof shall first be referred to the head of Bayer AG’s Head of R&D and CRISPR’s Chief Executive

	 	6.2.	Attorneys’ Fees. If any action at law or in equity (including, arbitration) is necessary to enforce or interpret the terms of this Agreement, including claims for fraud and/or fraudulent
inducement, the prevailing Party shall be entitled to reasonable attorneys’ fees, costs and necessary disbursements in addition to any other relief to which such Party may be entitled. 

 

	 	6.3.	Jurisdiction. Unless otherwise specified in this Agreement, each Party to this Agreement, by its execution hereof, unless otherwise prohibited by applicable Law (i) hereby irrevocably submits
to the exclusive jurisdiction of the state courts of the State of New York in the Borough of Manhattan and to the United States District Court for the Southern District of New York for the purpose of any action among the Parties, (ii) hereby waives
and agrees not to assert, by way of motion, as a defense or otherwise, in any such action, any claim that it is not subject personally to the jurisdiction of the above-named courts, that any such action brought in one of the above-named courts
should be dismissed on grounds of forum non conveniens, should be transferred or removed to any court other than one of the above-named courts, or should be stayed by reason of the pendency of some other proceeding in any court other than one of the
above-named courts, or that this Agreement or the subject matter hereof may not be enforced in or by such court and (iii) to the extent that an action can be commenced in a court, agrees not to commence any such action in any court
other than before one of the above-named courts. Notwithstanding the previous sentence, a Party hereto may commence any action in a court other than the above-named courts for the purpose of enforcing an order or judgment issued by one of the
above-named courts. 

  

	 	6.4.	Venue. No Party hereto will assert that venue should properly lie in any other location within the selected jurisdiction. 

 

	 	6.5.	Specific Performance. Each of the Parties hereto acknowledges and agrees that the other Party would be damaged irreparably in the event any of the provisions of this Agreement are not performed in
accordance with their specific terms or otherwise are breached or violated. Accordingly, each of the Parties hereto agrees that, without posting a bond or other undertaking, the other Party may seek (and obtain) an injunction or injunctions to
prevent breaches or violations of the provisions of this Agreement and to enforce specifically this Agreement and the terms and provisions hereof in any Action instituted in any court specified herein. An Action for specific performance as provided
herein shall not preclude a Party hereto from pursuing any other remedy to which such Party may be entitled, at law or in equity, in accordance with the terms of this Agreement. Each Party hereto further agrees that, in the event of any action for
specific performance in respect of such breach or violation, it will not assert that the defense that a remedy at law would be adequate provided, however, each Party hereto also agrees that any Party hereto can assert any other defense it may have
other than the defense of adequate remedy at law.  

  

	 	6.6.	Governing Law. The Parties agree that this Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

any such rights, interests or obligations without the prior written consent of the other Party is and shall be null and void ab initio; provided, however, that either of the Parties may, without consent of the other Party, assign its respective

hereunder. In addition to the requirements of the prior sentence, if this Agreement is assigned to a Third Party by a Party, as a condition to such assignment, all other Transaction Documents to which such Party is a party shall concurrently be

or receives from any patent office, including notice of all interferences, reissues, re-examinations, or oppositions, and all Patent-related filings, and by providing the other Parties the timely opportunity to have reasonable input into the
strategic aspects of such Prosecution and Maintenance. Although the Controlling Party shall have the final decision on responding to and taking any action with respect to the Prosecution and Maintenance of the Patents for which it is the Controlling
Party, it shall take into consideration any suggestions recommended by the other Parties’ patent counsel and reasonably incorporate any such changes. If there is a dispute among the Parties with respect to the Prosecution and Maintenance of
such Patents, Controlling Party shall take reasonable efforts not to abandon any rights that are in dispute until such time as a resolution can be reached. 

  

	 	(b)	The Controlling Party shall notify the other Parties in a timely manner of any decision not to prosecute or to abandon a Patent or pending application pertaining to the Joint Patents for which it is the Controlling
Party or not to defend a challenge of invalidity, unenforceability or patentability with respect to any Joint Patent, at which point, the other Parties according to the order specified in Section 2.2.4(a) shall become Controlling Party and
shall have the option, at its expense, of Prosecuting or Maintaining or defending any such pending application. In the event the Controlling Party determines at any time it does not want to pay any expenses for the Prosecution and/or Maintenance of
a Joint Patent in any country in the Territory, the Controlling Party shall notify the other Parties in a timely manner of such determination and the other Parties according to the order specified in Section 2.2.4(a) shall become the next
Controlling Party and shall have the right to prosecute and maintain such Joint Patent in such country in its sole name and at its sole cost and expense and the Controlling Party shall assign its undivided interest in such Joint Patent with respect

Operating Entity. In addition, such Party and its Affiliates shall not use such Information except in connection with the transactions or the performance of the obligations of such Party or such
Affiliate contemplated hereby or any other Transaction Document, the exercise of any rights hereunder or thereunder or as expressly provided for herein or therein. No Party or its Affiliates will disclose the Information of another Party or its
Affiliates, the Company or a Local Operating Entity to its Affiliates or its or their directors, officers, employees, representatives or agents unless such Person has a reasonable need to know such Information in connection with the transactions or
the performance of the obligations of such Party or such Affiliates contemplated hereby or any other Transaction Document, the exercise of any rights hereunder or thereunder or as expressly provided for herein or therein. No Party or its Affiliates
shall release or disclose such Information to any other Person, except those among its auditors, attorneys, financial advisors, bankers and consultants having a need to know such Information in connection with the transactions or the performance of
the obligations of such Party or such Affiliate contemplated hereby or any other Transaction Document, the exercise of any rights hereunder or thereunder, as required to comply with applicable Law or reporting requirements, or as expressly provided
for herein or therein, or to actual or potential acquirers, collaborators, licensees, sub-licensees investment bankers, investors or lenders. Each Person receiving any such Information shall be subject to customary confidentiality obligations prior
to such Person’s receipt of such Information and such Party shall be primarily liable and responsible for any breach of this Section 4.1 as if such Person was a party hereto. In addition, each Party and its Affiliates are permitted to
disclose such Information to the extent such disclosure is to a Governmental Authority as reasonably necessary in filing or prosecuting Patent, copyright and trademark applications, prosecuting or defending litigation related to this Agreement or
any other Transaction Document, complying with applicable governmental regulations with respect to performance under this Agreement or any other Transaction Document or otherwise required by applicable Law. If a Party or any of its Affiliates (the
“Compelled Party”) is requested to disclose any Information by any governmental or regulatory authority (including stock exchange rules, GAAP or IFRS), the Compelled Party will promptly notify the other Party(ies), as applicable
(the “Affected Party”), to permit it to seek a protective order or take other action that the Affected Party in its discretion deems appropriate, and the Compelled Party will cooperate in any such efforts to obtain a protective
order or other reasonable assurance that confidential treatment will be accorded such Information. If, in the absence of a protective order, the Compelled Party is compelled as a matter of Law to disclose any such Information in any proceeding or
pursuant to legal process (as advised by its outside legal counsel), the Compelled Party may disclose to the Person compelling disclosure only the part of such Information as is required by Law to be disclosed (in which case, prior to such
disclosure, the Compelled Party will advise and consult with the Affected Party and its counsel as to such disclosure and the nature and wording of such disclosure) and the Compelled Party will use its reasonable best efforts to obtain confidential
treatment therefor. The confidentiality obligations contained in this Section 4.1 do not apply to Information that can be shown by such Party to have been (i) previously known by the Party or its Affiliates to which it was furnished prior
to the date hereof (and not under a confidentiality obligation), (ii) generally available to the public through no fault or breach of such Party or its Affiliates,

or its Affiliates or its or their directors, officers, employees, representatives or agents without the use or reference to any Information of another Party, or their Affiliates, or any Local Operating Entity. For the avoidance of doubt, in no event
shall any information provided by a Party or its Affiliates (or one of its directors, officers, employees, representatives or agents) to another Party or its Affiliates be considered Information of the other Party or its Affiliates, except for any
Information created or developed under a service agreement between Bayer or CRISPR the Company or a Local Operating Entity. Following a termination of this Agreement, such confidentiality obligations and use restrictions shall be maintained, subject
to the exceptions set forth above, and all Information of the other Party(ies) and its Affiliates (including all copies thereof) shall be returned (or, at the other Party’s instructions, destroyed, with certification of the same) to the Party
that the other Party(ies) and its Affiliates shall be permitted to retain such Information (i) to the extent necessary for purposes of performing any continuing obligations or exercising any ongoing rights hereunder or under a Transaction
Document and, in any event, one copy of such Information retained by the other Party’s legal department for its records (provided that for so long as such Information is so retained, such Information shall be subject to the confidentiality
obligations and restrictions on use as set forth herein), and (ii) any computer records or files containing such Information that have been created solely by such Party’s or its Affiliates’ automatic archiving and back-up procedures,

of this Agreement. 

  

	4.3	Press Releases and Other Public Disclosures. No Party shall issue any press release or otherwise make any public statement with respect to this Agreement or the other Transaction Documents without the
prior written consent of the other Parties, except in case of public announcements required under the rules of any stock exchange on which the equity interests of a Party or its Affiliates (or any successor entity) are listed or any applicable Law
or governmental requirement. Notwithstanding anything to the contrary in this Article 4, a Party (or its Affiliates) may disclose this Agreement and the other Transaction Documents (and a summary thereof) as well as the financial statements of the
Company and Local Operating Entities and financial data derived therefrom, in securities filings with the U.S. Securities and Exchange Commission or an equivalent foreign agency to the extent required by applicable Law. In such event, the Party
seeking such disclosure shall prepare such summary and a proposed redacted version of this Agreement and/or the other Transaction Documents to request confidential treatment for such agreements, and the other Parties may promptly (and in any event,
no less than three (3) Business Days after receipt of such summary and proposed redactions) provide their comments. The Party seeking such disclosure shall reasonably consider any comments thereto provided by the other Parties within such three
(3) Business Day period.

	4.4	Publications. During the Term, each Party (as the “Requesting Party”) will submit to the other Party (as the “Reviewing Party”) for review and approval any proposed
academic, scientific and medical publication or public presentation to the extent it includes Information of the Reviewing Party. In each such instance, such review and approval will be conducted for the purposes of preserving the value of the
CRISPR Contributed Technology (for CRISPR) or the Bayer Background Technology (for Bayer) or the Company Program Technology (for Company) and determining whether any portion of the proposed publication or presentation containing the Reviewing
Party’s Information should be modified or deleted. Written copies of such proposed publication or presentation required to be submitted hereunder will be submitted to the Reviewing Party no later than 15 Business Days before submission for
publication or presentation (or five Business Days in advance in the case of an abstract). The Reviewing Party will provide its comments with respect to such publications and presentations within 10 Business Days of its receipt of such written copy
(or five Business Days in the case of an abstract). The review period may be extended for an additional 30 days if the Reviewing Party reasonably requests such extension including for the preparation and filing of patent applications.
Notwithstanding anything to the contrary, the Reviewing Party may require, in its reasonable discretion, that the Requesting Party redact the Reviewing Party’s Information from any such proposed publication or presentation. The Parties will
each comply with standard academic practice regarding authorship of scientific publications and recognition of contribution of other parties in any publication. Notwithstanding the foregoing, a Party’s obligation to submit any publication to
the Reviewing Party for review and approval under this Section 4.4 will not apply to any publication made by a Party with respect to Licensed Products for which such Party has completed an Opt-In Transaction that does not contain Information or
disclose any non-public information of the Reviewing Party (other than, for the avoidance of doubt, Information relating to the Licensed Products for which such Opt-In Transaction relates); provided, that where reasonably possible, such Party will
provide the Reviewing Party with an advance copy of such publication if such publication is reasonably likely to have a material adverse effect on the value of CRISPR Contributed Technology, Bayer Background Technology or Company Program Technology.
For clarity, neither Bayer nor CRISPR are obligated hereunder to submit proposed publications to the other Parties for all proposed publications relating to work conducted outside of the scope of this Agreement and the other Transaction Documents.

  

	4.5	Attorney-Client Privilege. No Party is waiving, nor will be deemed to have waived or diminished, any of its attorney work product protections, attorney client privileges or similar protections and
privileges as a result of disclosing information pursuant to this Agreement, or any of its Information (including Information related to pending or threatened litigation) to a receiving Party, regardless of whether the disclosing Party has asserted,
or is or may be entitled to assert, such privileges and protections. The Parties: (a) share a common legal and commercial interest in such disclosure that is subject to such privileges and protections; (b) are or may become joint
defendants in proceedings to which the information covered by such protections and privileges relates; (c) intend that such privileges and protections remain intact should a Party become subject to any actual or threatened proceeding to which
the disclosing Party’s Information covered by such protections and privileges relates; and (d) intend that after the Effective Date both the receiving Party(ies) and the disclosing Party will have the right to assert such protections and
privileges.

	5.1	Referral to Heads of Businesses. Unless otherwise specified in this Agreement, the Parties hereby agree that to the extent reasonably practicable and would not materially prejudice a Party, controversies
or claims arising out of or relating to this Agreement or the interpretation, performance, breach, termination or validity thereof shall first be referred to Bayer AG’s Head of R&D, CRISPR’s Chief Executive Officer and Company’s
Chief Executive Officer for resolution. If these individuals are unable to agree upon a resolution within thirty (30) days after referral of the matter to them, then a Party may pursue any available remedy hereunder, at law or in equity.

  

	5.2	Attorneys’ Fees. If any action at law or in equity (including, arbitration) is necessary to enforce or interpret the terms of this Agreement, including claims for fraud and/or fraudulent inducement,

and agrees not to assert, by way of motion, as a defense or otherwise, in any such action, any claim that it is not subject personally to the jurisdiction of the above-named courts, that any such action brought in one of the above-named courts
should be dismissed on grounds of forum non conveniens, should be transferred or removed to any court other than one of the above-named courts, or should be stayed by reason of the pendency of some other proceeding in any court other than one of the
above-named courts, or that this Agreement or the subject matter hereof may not be enforced in or by such court and (iii) to the extent that an action can be commenced in a court, agrees not to commence any such action in any court other than

	5.5	Specific Performance. Each of the Parties hereto acknowledges and agrees that the other Party would be damaged irreparably in the event any of the provisions of this Agreement are not performed in
accordance with their specific terms or otherwise are breached or violated. Accordingly, each of the Parties hereto agrees that, without posting a bond or other undertaking, the other Party may seek (and obtain) an injunction or injunctions to
prevent breaches or violations of the provisions of this Agreement and to enforce specifically this Agreement and the terms and provisions hereof in any Action instituted in any court specified herein. An Action for specific performance as provided
herein shall not preclude a Party hereto from pursuing any other remedy to which such Party may be entitled, at law or in equity, in accordance with the terms of this Agreement. Each Party hereto further agrees that, in the event of any action for
specific performance in respect of such breach or violation, it will not assert that the defense that a remedy at law would be adequate provided, however, each Party hereto also agrees that any Party hereto can assert any other defense it may have
other than the defense of adequate remedy at law. 

  

	5.6	Governing Law. The Parties agree that this Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

	 	(a)	No amendment, modification or addition to any provision of this Agreement shall be valid unless the same shall be in writing and approved by the signature of each Party. 

 

	 	(b)	The terms and conditions of this Agreement shall be interpreted according to the common sense meaning intended by the Parties and in accordance with the principles of good faith and fair dealing. 

 

	 	(c)	The Parties have participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly
by the Parties and no presumption or burden of proof shall arise favoring or disfavoring any Party by virtue of the authorship of any of the provisions of this Agreement. Any reference to any federal, state, local or foreign statute or law shall be
deemed also to refer to all rules and regulations promulgated thereunder, unless the context requires otherwise. 

  

	 	(d)	Every day commences at 12:00 a.m. and ends at 11:59 p.m. (midnight) New York time. Any reference in this Agreement to a number of days “in” which an action or notice is to be taken or given, shall be
interpreted in such way that the term commences the day after the date taken as reference and that the action or notice shall be validly taken or given at the last day. Any reference in this Agreement to a “day” or a number of
“days” without explicit qualification of “business” shall be interpreted as a reference to a calendar day or number of calendar days. If any action or notice is to be taken or given on or by a particular calendar day, and such

	 	(e)	In the event a Party becomes a debtor under Title 11 of the U.S. Code, this Agreement shall be deemed to be, for purposes of Section 365(n) of Title 11, a license to “Intellectual Property” as defined
therein and the other Party and its Affiliates, and each of their successors and assigns as licensees shall have the rights and elections as specified in Section 365(n) of Title 11 of the U.S. Code. Without limiting the foregoing, upon
termination of this Agreement by a trustee or executor of either Party which has rejected this Agreement pursuant to any non-contractual rights afforded to it by applicable bankruptcy law and/or a U.S. or foreign bankruptcy court or other tribunal
of competent jurisdiction, all rights and licenses herein granted to the other Party shall nonetheless continue in full force and effect in accordance with the terms of this Agreement. The debtor Party shall take such actions to provide similar
protections for the non-debtor Party pursuant to similar laws in other jurisdictions. 

  

	 	(f)	This Agreement shall constitute the entire agreement and understanding between the Parties and shall supersede and nullify any and all previous agreements, negotiations, commitments, undertakings and declarations

	 	(i)	Each provision contained in this Agreement is distinct and severable. A declaration of invalidity, illegality or unenforceability of any provision or a part thereof by an arbitrator, a court or a tribunal of competent
jurisdiction shall not affect the validity or enforceability of any other provision of this Agreement. To the extent permitted by law, if any provision of this Agreement, or the application thereof to any Person or any circumstance, is invalid or
unenforceable, (i) a suitable and equitable provision shall be substituted therefor in order to carry out, so far as may be valid and enforceable, the intent and purpose of such invalid or unenforceable provision and (ii) the remainder of
this Agreement and the application of such provision to other Persons or circumstances shall not be affected by such invalidity or unenforceability, nor shall such invalidity or unenforceability affect the validity or enforceability of such
provision, or the application thereof, in any other jurisdiction.

 30 

	 	(j)	Any mistaken reference to Articles, clauses, Sections, Schedules or paragraphs of this Agreement shall be amended according to common sense and good faith rules. When a reference is made in this Agreement to an Article,
clause, Section, Schedule or paragraph, such reference will be to an Article, clause, Section, Schedule or paragraph unless otherwise indicated. 

  

	 	(k)	No waiver by any Party of any default, misrepresentation or breach of warranty or covenant hereunder, whether intentional or not, shall be deemed to extend to any prior or subsequent default, misrepresentation or breach
of warranty or covenant hereunder or affect in any way any rights arising by virtue of any prior or subsequent such occurrence. No single or partial exercise of any right, power or privilege shall preclude any other or further exercise thereof or
the exercise of any other right, power or privilege unless explicitly provided for in this Agreement. 

  

	 	(l)	Subject to the terms of and restrictions in this Agreement, the reference to any Party shall include its successors or permitted transferees that have legally acquired its rights, obligations and/or duties. This
Agreement shall be binding upon and inure solely to the benefit of the Parties and their respective successors and permitted assigns and nothing herein, express or implied, is intended to or shall confer upon any other Person any legal or equitable
right, benefit or remedy of any nature whatsoever, unless otherwise specified therein. 

  

	 	(m)	EACH OF THE PARTIES HEREBY WAIVES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY WITH RESPECT TO ANY ACTION OR LIABILITY DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN
CONNECTION WITH THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH OF THE PARTIES HEREBY (A) CERTIFIES THAT NO REPRESENTATIVE OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN
THE EVENT OF ANY SUCH ACTION OR LIABILITY, SEEK TO ENFORCE THE FOREGOING WAIVER; AND (B) ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT, AS APPLICABLE, BY, AMONG OTHER
THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 5.3(l). 

  

	 	(n)	This Agreement may be executed and delivered (including by means of electronic transmission, such as by electronic mail in “.pdf” form) in two or more counterparts, and by the different Parties in separate
counterparts, each of which when executed shall be deemed to be an original, but all of which taken together shall constitute one and the same agreement. 

  

	 	(o)	Whenever the words “include,” “includes” or “including” are used in this Agreement, they will be deemed to be followed by the words “without limitation.” The words
“hereof,” “herein” and “hereunder” and words of similar import when used in this Agreement will refer to this Agreement as a whole and not to any particular provision of this Agreement. All terms used herein with
initial capital letters have the meanings ascribed to them herein and all terms

defined in this Agreement will have such defined meanings when used in any certificate or other document made or delivered pursuant hereto unless otherwise defined therein. The definitions
contained in this Agreement are applicable to the singular as well as the plural forms of such terms. Any agreement, instrument or statute defined or referred to herein, or in any agreement or instrument that is referred to herein, means such
agreement, instrument or statute as from time to time amended, modified or supplemented, including (in the case of agreements or instruments) by waiver or consent and (in the case of statutes) by succession of comparable successor statutes and
references to all attachments thereto and instruments incorporated therein. The use of “or” is not intended to be exclusive unless expressly indicated otherwise. References to sums of money are expressed in lawful currency of the United
States (U.S. dollars), unless the Parties otherwise agree in writing to use a different currency. 

  

	 	(p)	The Parties are independent contractors under this Agreement. Nothing herein contained 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, except to the extent specifically agreed to in a written agreement signed by the Parties. No 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, another Party, or to bind another Party in any respect whatsoever.

	 	7.	Notwithstanding anything herein to the contrary, the Tax Matters Partner shall not make any material filing, return, or election or take any material position in writing with respect to any U.S. federal, state, local or
foreign tax authority (a “Tax Decision”), without consulting in good faith with and obtaining the prior consent of the other Party which shall not be unreasonably withheld, conditioned or delayed, provided that, this requirement

 See Schedule 5.2.7
regarding Certain Co-Owner Consents ex-US. 
 5.2.11 

The Charpentier-licensed IP identified in Schedule 5.2.7 has been the subject of third party observations filed in the following patent offices: European
Patent Office, the UK Intellectual Property Office, the US Patent and Trademark Office and the World Intellectual Property Office (“Third Party Observations”). 

The Broad Institute is the applicant or owner of a series of competing cases claiming Crispr-Cas9 gene editing (which cases generally claim priority to one
or more provisional applications identifying at least Feng Zhang as an inventor, including without limitation U.S. provisional patent application 61/736,527, dated December 12, 2012, as well as foreign counterparts thereof). The Broad Institute has
filed Information Disclosure Statements in its various U.S. cases attacking the Charpentier-licensed IP, and it and/or related entities are considered to be among the parties filing third party observations. 

The Charpentier-UC applicants have filed a Suggestion of Interference Pursuant to 37 C.F.R. § 41.202 with the U.S. Patent & Trademark Office in
connection with numerous U.S. patents issued to the Broad Institute (the “Potential Interference”). The Suggestion of Interference was filed in U.S. Serial No. 13/842,859 on April 13, 2015. 

CRISPR has not, of record, filed any third party observations against adverse applicants (“TPOs Against Others”); [...***...].

 CRISPR has filed an opposition (“Opposition”) against the following grant to the Broad Institute in the European Patent Office: EP B1
277 1468. 
 The patent applications listed below and counterparts thereof generally include claims to Crispr-Cas9 gene editing with priority
applications filed in 2012, and there have since been numerous additional patent applications claiming variations of Crispr-Cas gene editing and various uses of Crispr-Cas gene editing for the development of potential products filed after 2012 that
are readily identifiable by searching patent databases for Crispr-Cas gene editing, which Third Party applicants, applications or patents (individually and collectively “Third Party IP”) could become involved in challenges related to the
Licensed Technology and/or to products to
