WHEREAS, this Employment Agreement shall become effective upon the later of the (i) full execution by both Parties; or (ii) ten (10) business days after the Company provided Executive with notice of this Agreement and the Exhibits (the “Effective Date”).

WHEREAS, the Company is a wholly owned subsidiary of CRISPR Therapeutics AG (“Parent” or “CRISPR AG”);

WHEREAS, Parent and the Company are each subject to the Swiss Ordinance act against excessive compensation in listed companies as a result of the of listing of the common shares of Parent on the NASDAQ Global Market; and

WHEREAS, the Company and the Executive are parties to that certain offer letter dated on or about October 12, 2021 (the “Prior Agreement”).

1. Position and Duties. The employment of the Executive by the Company will commence on the date hereof. The Executive will serve as the Senior Vice President, Chief Financial Officer of the Company. The Executive shall have responsibilities and duties consistent with such position and such other responsibilities and duties as may from time to time be prescribed by the Chief Executive Officer of the Company (the “CEO”) which are not inconsistent with the Executive’s skills and experience or his ability to discharge his responsibilities in the positions noted above. The Executive shall devote the Executive’s full working time and efforts to the business and affairs of the Company except as otherwise permitted under Section 3(b)(i). Notwithstanding the foregoing, the Executive may engage in charitable or other community activities, as long as such services and activities are disclosed to the Board of Directors of Parent (the “Board”) and do not materially interfere with the Executive’s performance of the Executive’s duties to the Company as provided in this Agreement. During the period which the Executive is employed pursuant to this Agreement (the “Employment Period”), the Executive’s principal place of employment will be in the Greater Boston, Massachusetts area; however, the Company may require the Executive to travel temporarily to other locations in connection with the Company’s business.

2. Compensation and Related Matters.

(a) Base Salary. During the Employment Period, the Company shall pay the Executive, as compensation for the performance of the Executive’s duties and obligations under this Agreement, an annual base salary of $435,000, payable in a manner that is consistent with the Company’s usual payroll practices for senior executives. The Executive’s base salary shall be reviewed annually by each of the Compensation Committee of the Board or any successor to such committee (the “Committee”) and the Board or for adjustment. Such adjustment, if any, shall be within the sole discretion of the Board. The annual base salary in effect at any given time is referred to herein as “Base Salary.”

(b) Annual Bonus. During the Employment Period, the Executive shall be eligible to receive an annual target bonus (a “Bonus”) if, as reasonably determined by the Board or, to the extent delegated by the Board, the Committee one or more of the performance targets annually determined by the Board or the Committee (“Performance Targets”) is achieved. If all of the Performance Targets are achieved, the Bonus will equal not less than 40 percent of the Executive’s Base Salary (the “Target Bonus”). In the event that less than all of the Performance Targets are met by Executive, the Bonus paid in respect of this paragraph may be less than the Target Bonus. Except as set forth in Section 5(a) hereof, the Executive must be employed by the Company on the day any such earned Bonus is paid which shall be not later than 2¹⁄₂ months after the end of each calendar year. The Executive’s target bonus opportunity as a percentage of Base Salary may be reviewed periodically and adjusted in the sole discretion of the Board. After any such adjustment, the term “Target Bonus” shall refer to the increased amount.

(c) Equity Compensation. The Executive shall be eligible to participate in Parent’s equity incentive plan according to its terms and conditions, as defined by Parent from time to time in its sole discretion. Both entitlement to any equity awards and the amount shall be determined by Parent in its sole discretion.

During the Employment Period, the Executive shall be entitled to receive reimbursement for all reasonable expenses incurred by him in performing services hereunder, in accordance with the policies and procedures then in effect and established by the Company for its senior executive officers.

(e) Other Benefits. During the Employment Period, the Executive shall be entitled to participate in or receive benefits under any employee benefit plan or arrangement currently maintained or which may, in the future, be made available by the Company generally to its executives and key management employees, subject to and on a basis consistent with the terms, conditions and overall administration of such plan or arrangement. Any payments or benefits payable to the Executive under a plan or arrangement referred to in this Section 2(e) in respect of any calendar year during which the Executive is employed by the Company for less than the whole of such year shall, unless otherwise provided in the applicable plan or arrangement, be prorated in accordance with the number of days in such calendar year during which the Executive is so employed. Should any such payments or benefits accrue on a fiscal (rather than calendar) year, then the proration in the preceding sentence shall be on the basis of a fiscal year rather than calendar year.

(f) Vacations. The Executive shall be entitled to accrue up to 20 paid vacation days in each year, which shall be accrued ratably. In other respects, the Company’s vacation policy as the same may then be in effect shall apply to vacations.

(g) Approval by Shareholders’ Meeting and Mandatory Law. Any compensation (including bonus, equity awards and fringe benefits) to be paid under this Agreement, is, to the extent required by Swiss laws and the Parent’s Article of Association, subject to approval by the general meeting of shareholders’ of Parent. In the event of a conflict between this Agreement and applicable mandatory Swiss law, the Company shall have the right to unilaterally modify the Agreement to the extent necessary to comply with mandatory law with immediate effect.

(h) Lost Opportunity Compensation. To offset losses the Executive incurred in connection with the transitioning of his employment to the Company, the Company will make a one-time payment to the Executive in the amount of $75,000 in the first payroll following 30 days of employment with the Company (usually within the first 60 days of employment). This payment is subject to the usual required withholdings. The Executive understands and agrees that, in the event his employment with the Company is terminated for any reason prior to November 14, 2022, he will reimburse the Company, within one (1) month after such employment termination, for this full amount ($75,000).

During such Administrative Leave, the Executive (A) may enter into consulting arrangements and accept board positions provided such outside business activities do not interfere with Executive’s obligations under this Agreement including without limitation, pursuant to Section 7 and (B) shall be free to engage in other employment provided that such employment does not interfere with Executive’s obligations under this Agreement including without limitation, pursuant to Section 7.

If any question shall arise as to whether during any period the Executive is disabled so as to be unable to perform the essential functions of the Executive’s then existing position or positions with or without reasonable accommodation, the Executive may, and at the request of the Company shall, submit to the Company a certification in reasonable detail by a physician selected by the Company to whom the Executive or the Executive’s guardian shall have no reasonable objection as to whether the Executive is so disabled or how long such disability is expected to continue, and such certification shall for the purposes of this Agreement be conclusive of the issue. The Executive shall cooperate with any reasonable request of the physician in connection with such certification. If such question shall arise and the Executive shall fail to submit such certification, the Company’s determination of such issue shall be binding on the Executive. Nothing in this Section 3(d) shall be construed to waive the Executive’s rights, if any, under existing law including, without limitation, the Family and Medical Leave Act of 1993, 29 U.S.C. §2601 et seq. and the Americans with Xxxxxxxxxxxx Xxx, 00 X.X.X. §00000 et seq.

(ii) Good Reason. For purposes of this Agreement, “Good Reason” shall mean that the Executive has complied with the “Good Reason Process” (hereinafter defined) following the occurrence of any of the following events: (i) a material diminution in the Executive’s responsibilities, authority and function, an adverse change to Executive’s job title, or a change in Executive’s reporting relationship that results in the Executive no longer reporting directly to the CEO; (ii) a material reduction in Base Salary except pursuant to a salary reduction program affecting substantially all of the employees of the Company, provided that it does not adversely affect the Executive to a greater extent than other similarly situated employees; (iii) a material change in the principal geographic location at which the Executive provides services to the Company outside of the Greater Boston, Massachusetts area; or (iv) the material breach of this Agreement by the Company (each a “Good Reason Condition”).

If the Company cures the Good Reason Condition during the Cure Period, Good Reason shall be deemed not to have occurred.

Except for termination as specified in Section 3(c), any termination of the Executive’s employment by either the Company or the Executive shall be communicated by written Notice of Termination to the other party hereto. For purposes of this Agreement, a “Notice of Termination” shall mean a notice which shall indicate the specific termination provision in this Agreement relied upon.

5. Change in Control.

(a) Acceleration of Vesting. In the event a Notice of Termination of an Involuntary Termination occurs during the CIC Period, and subject to the Executive signing, within 60 days following the Notice of Termination, a Release and the Release becoming effective and non-revocable within such 60-day period, all time based stock options and time based stock-based awards held by the Executive as of the date of the Notice of Termination, shall vest and become exercisable or nonforfeitable. Notwithstanding the foregoing, if, at the time of a Change in Control, the Company determines in its sole discretion, in reliance upon an opinion of counsel in form and substance satisfactory to the Company, that the acceleration in the prior sentence would not be permissible under applicable law, then in lieu of the acceleration in the prior sentence, all time based stock options and time based stock-based awards held by the Executive as of the date of such Change in Control, shall vest and become exercisable or nonforfeitable as of the date of such Change in Control.

(b) Excise Tax.

(i) Anything in this Agreement to the contrary notwithstanding, in the event that any compensation, payment or distribution by the Company to or for the benefit of the Executive, whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise (the “Parachute Payments”), would be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), the following provisions shall apply:

(A) If the Parachute Payments, reduced by the sum of (1) the Excise Tax and (2) the total of the Federal, state, and local income and employment taxes payable by the Executive on the amount of the Parachute Payments which are in excess of the Threshold Amount, are greater than or equal to the Threshold Amount, the Executive shall be entitled to the full benefits payable under this Agreement.

(B) If the Threshold Amount is less than (x) the Parachute Payments, but greater than (y) the Parachute Payments reduced by the sum of (1) the Excise Tax and (2) the total of the Federal, state, and local income and employment taxes on the amount of the Parachute Payments which are in excess of the Threshold Amount, then the Parachute Payments shall be reduced (but not below zero) to the extent necessary so that the sum of all Parachute Payments shall not exceed the Threshold Amount. In such event, the Parachute Payments shall be reduced in the following order: (1) cash payments not subject to Section 409A of the Code; (2) cash payments subject to Section 409A of the Code; (3) equity-based payments and acceleration; and (4) non-cash forms of benefits. To the extent any payment is to be made over time (e.g., in installments, etc.), then the payments shall be reduced in reverse chronological order.

(ii) For the purposes of this Section 5(c), “Threshold Amount” shall mean three times the Executive’s “base amount” within the meaning of Section 280G(b)(3) of the Code and the regulations promulgated thereunder less one dollar ($1.00); and “Excise Tax” shall mean the excise tax imposed by Section 4999 of the Code, and any interest or penalties incurred by the Executive with respect to such excise tax.

(iii) All calculations and determinations under Sections 5(c)(i) and 5(c)(ii) shall be made by an independent accounting firm or independent tax counsel appointed by the Company (the “Tax Counsel”) whose determinations shall be conclusive and binding on the Company and the Executive for all purposes. For purposes of making the calculations and determinations required by Sections 5(c)(i) and 5(c)(ii), the Tax Counsel may rely on reasonable, good faith assumptions and approximations concerning the application of Section 280G and Section 4999 of the Code. The Company and the Executive shall furnish the Tax Counsel with such information and documents as the Tax Counsel may reasonably request in order to make its determinations under Sections 5(c)(i) and 5(c)(ii). The Company shall bear all costs the Tax Counsel may reasonably incur in connection with its services.

(i) any “person,” as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended (the “Act”) (other than Parent, any of its subsidiaries, or any trustee, fiduciary or other person or entity holding securities under any employee benefit plan or trust of Parent or any of its subsidiaries), together with all “affiliates” and “associates” (as such terms are defined in Rule 12b-2 under the Act) of such person, shall become the “beneficial owner” (as such term is defined in Rule 13d-3 under the Act), directly or indirectly, of securities of Parent representing 50 percent or more of the combined voting power of the Company’s then outstanding securities having the right to vote in an election of the Board (“Voting Securities”) (in such case other than as a result of an acquisition of securities directly from Parent); or

(ii) the date a majority of the members of the Board is replaced during any 12-month period by directors whose appointment or election is not endorsed by a majority of the members of the Board before the date of the appointment or election; or

(iii) the consummation of (A) any consolidation or merger of Parent where the stockholders of Parent, immediately prior to the consolidation or merger, would not, immediately after the consolidation or merger, beneficially own (as such term is defined in Rule 13d-3 under the Act), directly or indirectly, shares representing in the aggregate more than 50 percent of the voting shares of the company issuing cash or securities in the consolidation or merger (or of its ultimate parent corporation, if any), or (B) any sale or other transfer (in one transaction or a series of transactions contemplated or arranged by any party as a single plan) of all or substantially all of the assets of Parent.

Notwithstanding the foregoing, a “Change in Control” shall not be deemed to have occurred for purposes of the foregoing clause (i) solely as the result of an acquisition of securities by Parent which, by reducing the number of shares of Voting Securities outstanding, increases the proportionate number of Voting Securities beneficially owned by any person to 50 percent or more of the combined voting power of all of the then outstanding Voting Securities; provided, however, that if any person referred to in this sentence shall thereafter become the beneficial owner of any additional shares of Voting Securities (other than pursuant to a stock split, stock dividend, or similar transaction or as a result of an acquisition of securities directly from Parent) and immediately thereafter beneficially owns 50 percent or more of the combined voting power of all of the then outstanding Voting Securities, then a “Change in Control” shall be deemed to have occurred for purposes of the foregoing clause (i). For the avoidance of doubt, a migratory merger of Parent for the principal purpose of redomiciling Parent shall not constitute a Change in Control.

6. Section 409A.

(a) Anything in this Agreement to the contrary notwithstanding, if at the time of the Executive’s separation from service within the meaning of Section 409A of the Code, the Company determines that the Executive is a “specified employee” within the meaning of Section 409A(a)(2)(B)(i) of the Code, then to the extent any payment or benefit that the Executive becomes entitled to under this Agreement on account of the Executive’s separation from service would be considered deferred compensation subject to the 20 percent additional tax imposed pursuant to Section 409A(a) of the Code as a result of the application of Section 409A(a)(2)(B)(i) of the Code, such payment shall not be payable and such benefit shall not be provided until the date that is the earlier of (A) six months and one day after the Executive’s separation from service, or (B) the Executive’s death. If any such delayed cash payment is otherwise payable on an installment basis, the first payment shall include a catch-up payment covering amounts that would otherwise have been paid during the six-month period but for the application of this provision, and the balance of the installments shall be payable in accordance with their original schedule. Solely for purposes of Section 409A of the Code, each installment payment under this Agreement is considered a separate payment.

(b) All in-kind benefits provided and expenses eligible for reimbursement under this Agreement shall be provided by the Company or incurred by the Executive during the time periods set forth in this Agreement. All reimbursements shall be paid as soon as administratively practicable, but in no event shall any reimbursement be paid after the last day of the taxable year following the taxable year in which the expense was incurred. The amount of in-kind benefits provided or reimbursable expenses incurred in one taxable year shall not affect the in-kind benefits to be provided or the expenses eligible for reimbursement in any other taxable year. Such right to reimbursement or in-kind benefits is not subject to liquidation or exchange for another benefit.

(c) To the extent that any payment or benefit described in this Agreement constitutes “non-qualified deferred compensation” under Section 409A of the Code, and to the extent that such payment or benefit is payable upon the Executive’s termination of employment, then such payments or benefits shall be payable only upon the Executive’s “separation from service.” The determination of whether and when a separation from service has occurred shall be made in accordance with the presumptions set forth in Treasury Regulation Section 1.409A-1(h).

(d) The parties intend that this Agreement will be administered in accordance with Section 409A of the Code. To the extent that any provision of this Agreement is ambiguous as to its compliance with Section 409A of the Code, the provision shall be read in such a manner so that all payments hereunder comply with Section 409A of the Code. The parties agree that this Agreement may be amended, as reasonably requested by either party, and as may be necessary to fully comply with Section 409A of the Code and all related rules and regulations in order to preserve the payments and benefits provided hereunder without additional cost to either party.

(e) The Company makes no representation or warranty and shall have no liability to the Executive or any other person if any provisions of this Agreement are determined to constitute deferred compensation subject to Section 409A of the Code but do not satisfy an exemption from, or the conditions of, such Section.

7. Proprietary Information, Noncompetition and Cooperation.

(a) Confidentiality and Assignment Agreement. The Executive has entered into the Proprietary Information and Inventions Agreement (the “Confidentiality and Assignment Agreement”), attached hereto as Exhibit A, the terms of which are incorporated by reference as material terms of this Agreement. For purposes of this Agreement, the obligations in this Section 7 and those that arise in the Confidentiality and Assignment Agreement, and any other agreement relating to confidentiality, assignment of inventions, or other restrictive covenants shall collectively be referred to as the “Continuing Obligations.”

(b) Non-Solicitation. In order to protect the Company’s proprietary information and good will, during the Executive’s employment with the Company and for a period of twelve (12) months following the (i) the delivery of a Notice of Termination, in the case of an Involuntary Departure or (ii) the termination of the Executive’s employment for any other reason (the “Restricted Period,) the Executive will not, directly or indirectly, in any manner, other than for the benefit of the Company (i) divert or take away customers of the Company or any of its suppliers; and/or (ii) solicit, entice, attempt to persuade any other employee or consultant of the Company to leave the Company for any reason (other than the termination of subordinate employees undertaken in the course of the Executive’s employment with the Company). The Executive acknowledges and agrees that if the Executive violates any of the provisions of this paragraph 7(b), the running of the Restricted Period will be extended by the time during which the Executive engages in such violation(s).

(c) Noncompetition. The Executive acknowledges and agrees that in consideration and as a condition of the Executive’s promotion by the Company and in exchange for, among other things, the benefits contained in this Agreement, including without limitation the opportunity to receive enhanced post-employment severance benefits, which the Executive acknowledges and agrees is fair and reasonable consideration that is independent from the continuation of the Executive’s employment, during the Restricted Period the Executive will not directly or indirectly, whether as owner, partner, shareholder, director, manager, consultant,

agent, employee, co-venturer or otherwise, engage, participate or invest in any Competing Business anywhere in the world. For purposes hereof, the term “Competing Business” shall mean any entity engaged in the discovery, development or commercialization of gene editing technology for human therapeutics. Notwithstanding the foregoing, nothing contained hereinabove or hereinbelow shall be deemed to prohibit the Executive from (i) acquiring, solely as an investment, shares of capital stock (or other interests) of any corporation (or other entity) not exceeding 2% of such corporation’s (or other entity’s) then outstanding shares of capital stock (or equity interest), or (ii) working for a line of business, division or unit of a larger entity that competes with the Company as long as the Executive’s activities for such line of business, division or unit do not involve work by the Executive on matters that are directly competitive with the Company’s business. Notwithstanding the foregoing, this Section 7(c) shall not be enforceable during the post-employment portion of the Restricted Period if the Executive is terminated by the Company without Cause, is laid off from employment or if the Company elects to waive the restrictions set forth in this Section 7(c). If Section 7(c) is enforced during the post-employment portion of the Restricted Period, the Company shall pay the Executive at the rate of 50% of the highest annualized base salary paid to the Executive within the two year period preceding the last day of Executive’s employment (the “Garden Leave Pay”) during the post-employment portion of the Restricted Period. During the Restricted Period Executive will promptly (and immediately upon request) notify the Company of any change in address and each subsequent employer or business activity including the name and address of employer or other post-Company plans and the nature of Executive’s activities. The Company’s election not to provide post-employment Garden Leave Pay shall be deemed a waiver of Executive’s post-employment noncompetition obligations under this Section 7(c). In no event will Garden Leave Pay be duplicative of other pay and the Executive agrees that any Garden Leave Pay received pursuant to this Section 7(c) shall reduce (and shall not be in addition to) any other pay that the Executive may be entitled to receive during the post-employment portion of the Restricted Period. The Executive acknowledges that he has been advised by the Company that he has the right to consult with counsel regarding the noncompetition restrictions contained in this Section 7(c) prior to executing this Agreement.

(d) Litigation and Regulatory Cooperation. During and after the Executive’s employment, the Executive shall use reasonable efforts to cooperate with the Company in the defense or prosecution of any claims or actions now in existence or that may be brought in the future against or on behalf of the Company that relate to events or occurrences that transpired while the Executive was employed by the Company. The Executive’s cooperation in connection with such claims or actions shall include, but not be limited to, being available to meet with counsel to prepare for discovery or trial and to act as a witness on behalf of the Company at mutually convenient times. During and after the Executive’s employment, the Executive shall use reasonable efforts to cooperate with the Company in connection with any investigation or review of any federal, state or local regulatory authority as any such investigation or review relates to events or occurrences that transpired while the Executive was employed by the Company. The Company shall reimburse the Executive for any reasonable out-of-pocket expenses incurred in connection with the Executive’s performance of obligations pursuant to this Section 7(c).

(e) Injunction. The Executive agrees that it would be difficult to measure any damages caused to the Company that might result from any breach by the Executive of the

promises set forth in this Section 7 and the Confidentiality and Assignment Agreement, and that in any event money damages would be an inadequate remedy for any such breach. Accordingly, subject to Section 8 of this Agreement, the Executive agrees that if the Executive breaches, or proposes to breach, any portion of this Agreement and the Confidentiality and Assignment Agreement, the Company shall be entitled, in addition to all other remedies that it may have, to an injunction or other appropriate equitable relief to restrain any such breach without showing or proving any actual damage to the Company.
