2.              POSITION & DUTIES.

(a)            Except as provided in Section 2(b) below, the Executive shall serve as the Head of Research and Development of the Company and its subsidiary, Eloxx Pharmaceuticals, Ltd. during the Employment Term. The Executive shall have such duties, authorities and responsibilities as are commensurate with the Executive’s position and such other duties and responsibilities as the Company’s Chief Executive Officer shall designate that are consistent with the Executive’s position. The Executive agrees to serve, if requested, without additional compensation, as an officer or director of any of the Company’s subsidiaries.

(b)           During the Employment Term, the Executive agrees to devote his full business time, attention and energies to the performance of all of the lawful duties, responsibilities and authority that may be assigned to him hereunder. Nothing contained in this Agreement will preclude the Executive from (i) devoting time to personal and family investments, (ii) serving as a director of any not-for-profit company, (iii) serving as a director for any for-profit company that is approved by the Chief Executive Officer (such approval not to be unreasonably withheld) or (iv) from participating in charitable or industry associations, in each case, provided that such activities or services do not (x) materially interfere with the Executive’s performance of duties hereunder or (y) violate the terms of the Confidentiality Agreement (as defined below).

(c)            During the Employment Term, the Executive’s principal place of employment shall be the Company’s offices in Watertown, Massachusetts, subject to customary business travel consistent with the Executive’s duties and responsibilities.

3.              BASE SALARY. The Company agrees to pay the Executive a base salary (the “Base Salary”) at an annual rate of US $425,000. The Base Salary will be payable bimonthly in accordance with the regular payroll practices of the Company. The Executive’s Base Salary shall be subject to review by the Board of Directors of the Company (the “Board”) (or a Committee thereof) at least annually and may be increased, but not decreased, from time to time by the Board. The base salary as determined herein from time to time shall constitute “Base Salary” for purposes of this Agreement.

4.              ANNUAL BONUS; STRETCH BONUS. With respect to each full calendar year during the Employment Term, the Executive shall be eligible to earn (a) an annual, performance-based bonus (an “Annual Bonus”) with a target bonus value equal to forty percent (40%) of the Executive’s Base Salary (the “Target Bonus”) which shall be earned if at all based upon the achievement of performance targets established by the Board (or a committee thereof), in consultation with the Executive, within the first 90 days of each calendar year during the Employment Term (provided that, notwithstanding the foregoing, Executive acknowledges and agrees that the performance targets applicable to the Annual Bonus for the 2021 calendar year were established prior to the Effective Date), and (b) an annual stretch bonus, with a stretch bonus opportunity of twenty five percent (25%) of the Executive’s Base Salary, which shall be earned if at all based upon the determination by the Board (or a committee thereof) of performance by the Executive and/or the Company for such calendar year, and/or such other factors as determined by the Board (or a committee thereof) in its sole discretion (the “Stretch Bonus”), with the actual amount of the Annual Bonus or Stretch Bonus for a particular year determined by the Board (or a committee thereof) in its sole discretion. The Board (or a committee thereof) shall consider the Executive’s and the Company’s performance in the entire 2021 calendar year without regard to the Effective Date when determining the Executive’s Annual Bonus and Stretch Bonus for the 2021 calendar year and neither such bonus shall be subject to pro-ration in the 2021 calendar year.

(a)            TIME-VESTING AWARDS. (i) A stock option to purchase 711,619 shares of Common Stock (the “Option Award”) on the Grant Date will vest and become exercisable or payable, respectively, with respect to 1/4 of the shares on the first anniversary of the Grant Date and with respect to an additional 1/12 of the shares on each quarterly anniversary of the Grant Date thereafter, subject to the Executive’s continued employment with the Company through each such date and with the other terms contained in the form of award attached hereto as Appendix B and (ii) restricted stock units representing 44,683 Common Stock (A) to vest in a single installment on December 1, 2021, subject to the Executive’s continued service through such date and full accelerated vesting upon an earlier termination of Executive’s employment without Cause, by the Executive for Good Reason or as a result of the Executive’s death or Disability, (B) providing that the Executive shall establish a Rule 10b5-1 Plan as soon as practicable following the Effective Date in order to satisfy the federal, state, or local tax withholding obligations upon settlement of the restricted stock units by directing a broker to sell shares of Common Stock issuable upon settlement of the restricted stock units; provided that if the Executive is not permitted to establish a Rule 10b5-1 Plan prior to November 15, 2021 and is prohibited from trading in the Company’s securities under a Company policy or applicable law on the settlement date of the restricted stock units, then the Executive shall have the right to elect to have the Company withhold shares otherwise issuable upon settlement of the restricted stock units in satisfaction of the applicable tax withholdings in accordance with Section 8(h)(ii) of the Plan and (C) with the other terms and conditions contained in the form of award attached hereto as Appendix C. The vesting of any such awards, shall accelerate and such awards shall become fully vested and exercisable or payable, respectively, immediately prior to a Corporate Transaction (as defined in the 2018 Equity Incentive Plan). In the event of the first equity financing that (I) results in proceeds for the Company of at least $20,000,000, and (II) results in dilution to the percentage of the Common Stock represented by the Option Award, determined on a fully diluted and, as applicable, a fully converted basis (a “Qualifying Financing”), the Company will, within five days following the consummation of such Qualifying Financing, grant to Executive additional options to purchase Common Stock under the Plan (the “Additional Options”) such that the percentage of shares of Common Stock covered by the Option Award and the Additional Options, taken together, immediately following the consummation of the Qualifying Financing, determined on a fully diluted and, as applicable, a fully converted basis, equals the percentage of shares of Common Stock covered by the Option Award immediately prior to the consummation of the Qualifying Financing, in each case determined on a fully-diluted basis. The Additional Options shall have terms consistent with the Option Award (except for the exercise price, which will be the fair market value on the date of grant).

(b)       ANNUAL AWARDS. Each year, the Executive will be eligible for annual awards of stock options and or restricted stock units as determined by the Board. Nothing herein shall be construed as an obligation to grant such awards, which shall be subject to the sole discretion of the Board. The vesting of any such awards, shall accelerate and such awards shall become fully vested and exercisable or payable, respectively, immediately prior to a Corporate Transaction (as defined in the 2018 Equity Incentive Plan).

(c)       TAX WITHHOLDING. At Executive’s request, the Company will withhold from the shares of Common Stock otherwise payable to Executive with respect to vested portions of the equity awards the number of whole shares of Common Stock required to satisfy the applicable tax withholding obligation, the number of shares so withheld to be determined by the Company based on the fair market value of the Common Stock on the date the Company is required to withhold.

Subject to satisfaction of each of the conditions set forth in Section 9, the following amounts and benefits shall be due to the Executive:

(a)            DISABILITY. Upon employment termination due to Disability, the Company shall pay or provide the Executive: (i) any unpaid Base Salary through the date of termination and any accrued vacation; (ii) reimbursement for any unreimbursed expenses owed to Executive; and (iii) all other payments and benefits to which the Executive is entitled under the terms of any applicable compensation arrangement or benefit, equity or other plan or program, including but not limited to any applicable insurance benefits, payable on the next regularly scheduled Company payroll date following the date of termination or earlier if required by applicable law (collectively, “Accrued Amounts”). In addition, upon the Executive’s termination due to Disability, the Company shall pay the amounts described in Sections 8(d)(3) and 8(d)(4) to the Executive.

(b)           DEATH.

In addition, upon the Executive’s death, the Company shall pay the amounts described in Sections 8(d)(3) and 8(d)(4) to the Executive’s estate.

(c)            TERMINATION FOR CAUSE OR WITHOUT GOOD REASON. If the Executive’s employment should be terminated (i) by the Company for Cause, or (ii) by the Executive without Good Reason, the Company shall pay to the Executive any Accrued Amounts only, and shall not be obligated to make any additional payments to the Executive.

(d)           TERMINATION WITHOUT CAUSE OR FOR GOOD REASON. If the Executive’s employment by the Company is terminated by the Company other than for Cause (and not due to Disability or death) or by the Executive for Good Reason, other than in circumstances described in Section 8(e), then the Company shall pay or provide the Executive with the Accrued Amounts and subject to compliance with Section 9:

(1)           the Executive’s Base Salary as in effect immediately preceding the last day of the Employment Term for a period of twelve (12) months following the termination date (the “Salary Severance Period”) payable in a lump sum in cash promptly following the termination date (for purposes of calculating the Executive’s severance benefits, the Executive’s Base Salary shall be calculated based on the rate in effect prior to any material reduction in Base Salary that would give the Executive the right to resign for Good Reason (as provided in Section 7(e)(1)));

(2)           if the Executive timely elects continued coverage under COBRA for himself and his covered dependents under the Company’s group health plans following such termination, then the Company shall pay the COBRA premiums necessary to continue the Executive’s and his covered dependents’ health insurance coverage in effect on the termination date until the earliest of (i) twelve (12) months following the termination date (the “COBRA Severance Period”); (ii) the date when the Executive becomes eligible for substantially equivalent health insurance coverage in connection with new employment or self-employment; or (iii) the date the Executive ceases to be eligible for COBRA continuation coverage for any reason, including plan termination (such period from the termination date through the earlier of (i)-(iii), the “COBRA Payment Period”). Notwithstanding the foregoing, if at any time the Company determines that its payment of COBRA premiums on the Executive’s behalf would result in a violation of applicable law (including but not limited to the 2010 Patient Protection and Affordable Care Act, as amended by the 2010 Health Care and Education Reconciliation Act), then in lieu of paying COBRA premiums pursuant to this Section 8(d)(2), the Company shall pay the Executive on the last day of each remaining month of the COBRA Payment Period, a fully taxable cash payment equal to the COBRA premium for such month, subject to applicable tax withholding (such amount, the “Special Severance Payment”), such Special Severance Payment to be made without regard to the Executive’s payment of COBRA premiums. Nothing in this Agreement shall deprive the Executive of his rights under COBRA or ERISA for benefits under plans and policies arising under his employment by the Company.

(4)           in the event that the Executive’s employment is terminated: (i) on or before the date Annual Bonus performance goals are established for the performance year in which the Executive’s termination occurs, the Executive shall receive a pro-rata portion of the Executive’s Target Bonus for the performance year in which the Executive’s termination occurs, with such pro-rata portion calculated based upon the number of days that the Executive was employed during such performance year divided by the total number of days in such performance year; or (ii) after the date Annual Bonus performance goals are established for the performance year in which the Executive’s termination occurs (but on or before December 31 of such performance year), the Executive shall receive a pro-rata portion of the Executive’s Target Bonus for the performance year in which the Executive’s termination occurs, with such pro-rata portion calculated based upon the Executive’s achievement of performance goals as determined by the Board in good faith, payable in either case as a lump sum payment on the Company’s first ordinary payroll date occurring on or after the General Release effective date (namely, the date it can no longer be revoked) or as soon thereafter as is reasonable practicable thereafter; and

(5)           if such termination occurs prior to the second anniversary of the Effective Date, an additional fifty percent (50%) of the shares subject to all stock options, restricted stock units and other equity awards which are time-based and are then held by the Executive shall vest and become exercisable or payable, as applicable, and an additional fifty percent (50%) of the performance-based awards shall vest based on target performance and (z) if such termination occurs on or after the second anniversary of the Effective Date, all of the shares subject to all stock options, restricted stock units and other equity awards which are time-based and are then held by the Executive shall vest and become exercisable or payable, as applicable, and all performance-based awards shall vest based on target performance. In addition, the time period that the Executive may have to exercise any stock options shall be extended for a period equal to the shorter of (i) one (1) year or (ii) the remaining term of the award; provided, however, that if any particular equity or equity-based award provides for more favorable termination treatment, then the more favorable treatment provided therein will apply.

(e)            TERMINATION WITHOUT CAUSE OR FOR GOOD REASON FOLLOWING A CORPORATE TRANSACTION. If the Executive’s employment by the Company is terminated by the Company other than for Cause (and not due to Disability or death), or by the Executive for Good Reason, in either case on or within twenty-four (24) months immediately following a Corporate Transaction, then the Company shall pay or provide the Executive with the Accrued Amounts and all of the benefits described in Section 8(d) above, subject to compliance with Section 9; provided that: (i) the Salary Severance Period defined in Section 8(d)(1) shall be increased to a total of eighteen (18) months following the termination date; (ii) the COBRA Severance Period defined in Section 8(d)(2) shall be increased to a total of eighteen (18) months following the termination date; and (iii) in lieu of the pro-rata bonus described in Section 8(d)(4), the Company shall pay the Executive the full Target Bonus for the performance year in which the Executive’s termination occurs, payable as a lump sum payment on the Company’s first ordinary payroll date occurring on or after the General Release effective date (namely, the date it can no longer be revoked).

9.              CONDITIONS. Any payments or benefits made or provided pursuant to Section 8 (other than Accrued Amounts) are subject to the Executive’s (or, in the event of the Executive’s death, the beneficiary’s or estate’s, or in the event of the Executive’s Disability, the guardian’s):

(a)            compliance with the provisions of Section 10 hereof;

(b)           delivery to the Company of the executed Agreement and General Release (the “General Release”), which shall be in the form attached hereto as Appendix A (with such changes therein or additions thereto as needed under then applicable law to give effect to its intent and purpose) within 21 days following the date of termination of employment, and permitting the General Release to become effective in accordance with its terms; and

(c)            delivery to the Company of a resignation from all offices, directorships and fiduciary positions with the Company, its affiliates and employee benefit plans, by no later than 90 days following termination of employment.

Notwithstanding the due date of any post-employment payments, any amounts due following a termination under this Agreement (other than Accrued Amounts) shall not be due until after the expiration of any revocation period applicable to the General Release without the Executive having revoked such General Release, and any such amounts shall be paid or commence being paid to the Executive on the Company’s first ordinary payroll date occurring on or after the expiration of such revocation period without the occurrence of a revocation by the Executive (or such later date as may be required under Section 17 or the final sentence of this Section 9). Nevertheless (and regardless of whether the General Release has been executed by the Executive), upon any termination of Executive’s employment, Executive shall be entitled to receive any Accrued Amounts, payable after the date of termination in accordance with the Company’s applicable plan, program, policy or payroll procedures. Notwithstanding anything to the contrary in this Agreement, if any severance pay or benefits are deferred compensation under Section 409A (as defined below), and the period during which the Executive may sign the General Release begins in one calendar year and ends in another, then the severance pay or benefit shall not be paid or the first payment shall not occur until the later calendar year.

10.           CONFIDENTIALITY AND POST-EMPLOYMENT OBLIGATIONS. As a condition of employment, the Executive agrees to execute and abide by the Company’s current form of Confidentiality and Non-Competition Agreement (“Confidentiality Agreement”), which may be amended by the parties from time to time without regard to this Agreement. The Confidentiality Agreement contains provisions that are intended by the parties to survive and do survive termination of this Agreement.

The validity, interpretation, construction and performance of this Agreement shall be governed by the laws of the Commonwealth of Massachusetts without regard to its conflicts of law principles.

17.           SECTION 409A.

(a)            Notwithstanding anything to the contrary herein, the following provisions apply to the extent severance benefits provided herein are subject to Section 409A of Code and the regulations and other guidance thereunder and any state law of similar effect (collectively “Section 409A”). Severance benefits payable upon a termination of employment shall not commence until Executive has a “separation from service” for purposes of Section 409A. Each installment of severance benefits is a separate “payment” for purposes of Treas. Reg. Section 1.409A-2(b)(2)(i), and the severance benefits are intended to satisfy the exemptions from application of Section 409A provided under Treasury Regulations Sections 1.409A-1(b)(4), 1.409A-1(b)(5) and 1.409A-1(b)(9). However, if such exemptions are not available and Executive is, upon separation from service, a “specified employee” for purposes of Section 409A, then, solely to the extent necessary to avoid adverse personal tax consequences under Section 409A, the timing of the severance benefits shall be delayed until the earlier of (i) six (6) months and one day after Executive’s separation from service, or (ii) Executive’s death. Any payment or benefit otherwise payable or to be provided in the six (6) month period following separation from service that is not so paid or provided by reason of this Section 17 shall be accumulated and paid or provided in a single lump sum, as soon as practicable (and in all events within 15 days) after the date that is six (6) months after Executive’s separation from service (or, if earlier, as soon as practicable, and in all events within 15 days, after the date of Executive’s death)

(b)           It is intended that this Agreement shall comply with the requirements of Section 409A, and any ambiguity contained herein shall be interpreted in such manner so as to avoid adverse personal tax consequences under Section 409A. Notwithstanding the foregoing, the Company shall in no event be obligated to indemnify the Executive for any taxes or interest that may be assessed by the IRS pursuant to Section 409A of the Code on payments made pursuant to this Agreement.

18.           MITIGATION OF DAMAGES. In no event shall the Executive be obliged to seek other employment or take any other action by way of mitigation of the severance benefits payable to the Executive under any of the provisions of this Agreement, nor shall the amount of any severance benefit hereunder be reduced by any compensation earned by the Executive as a result of employment by another employer, except as set forth in this Agreement.

AGREEMENT AND GENERAL RELEASE

Eloxx Pharmaceuticals, Inc. (the “Company”) and Vijay Modur (“Executive”) agree:

1.              Last Day of Employment. Executive’s last day of employment with Employer was [INSERT DATE] (the “Termination Date”). In addition, effective as of the Termination Date, Executive ceased to serve as the General Counsel of the Company and its affiliates and ceased to be eligible for any benefits or compensation from the Company and its affiliates other than as specifically provided in Section 8 of the Executive Employment Agreement between the Company and Executive dated as of April 1, 2021 (the “Employment Agreement”). Executive further acknowledges and agrees that from and after the date Executive executes this Agreement and General Release, Executive will not represent (and since the Termination Date the Executive has not represented) the Executive as being a director, employee, officer, trustee, agent or representative of the Company or its affiliates for any purpose. In addition, effective as of Termination Date, Executive resigns from all offices, directorships, trusteeships, committee memberships and fiduciary capacities held with, or on behalf of, the Company and its affiliates or any benefit plans of the Company and its affiliates. These resignations will become irrevocable as set forth in Section 3 below.

2.              Consideration. The parties acknowledge that this Agreement and General Release is being executed in accordance with Section 9 of the Employment Agreement.

3.              Revocation. Executive may revoke this Agreement and General Release for a period of seven (7) calendar days following the day Executive executes this Agreement and General Release. Any revocation within this period must be submitted in writing to the Company and state, “I hereby revoke my acceptance of our Agreement and General Release.” The revocation must be delivered to the Company, Eloxx Pharmaceuticals, Inc., 950 Winter Street, Waltham, MA 02451, or any executive officer of the Company. This Agreement and General Release shall become effective and irrevocable on the eighth (8th) day after Executive executes it, unless earlier revoked by Executive in accordance with this Section 3 (the “Effective Date”).

4.              General Release of Claims. (A) Executive and the Executive’s heirs, executors, administrators, successors and assigns (collectively referred to throughout this Agreement as “Employee”) knowingly and voluntarily release and forever discharge the Company and its affiliates, subsidiaries, divisions, benefit plans, successors and assigns in such capacity, and the current, future and former employees, officers, directors, trustees and agents thereof (collectively referred to as “Employer”) from any and all actions, causes of action, contributions, indemnities, duties, debts, sums of money, suits, controversies, restitutions, understandings, agreements, promises, claims regarding stock, stock options or other forms of equity compensation, commitments, damages, fees and liabilities, responsibilities and any and all claims, demands, executions and liabilities of whatsoever kind, nature or description, oral or written, known or unknown, matured or unmatured, suspected or unsuspected at the present time, in law or in equity, whether known and unknown, against Employer, which the Employee has, has ever had or may have as of the date of Executive’s execution of this Agreement and General Release, including, but not limited to, any alleged violation of:

Notwithstanding anything herein to the contrary, the sole matters to which the Agreement and General Release do not apply are: (i) Employee’s express rights or claims for accrued vested benefits under any employee benefit plan, policy or arrangement maintained by Employer or under COBRA; (ii) Employee’s rights under the provisions of the Employment Agreement which are intended to survive termination of employment; ; or (iii) any rights of the Executive to indemnification as a Director or Officer of the Company.

5.              No Claims Permitted. Employee waives Executive’s right to file any charge or complaint against Employer arising out of Executive’s employment with or separation from Employer before any federal, state or local court or any state or local administrative agency, except where such waivers are prohibited by law (with the understanding that that this Agreement and General Release bars the Executive from recovering monetary relief from Employer in connection with any charges or complaints which are not waived hereunder).

Furthermore, nothing in this Agreement or General Release and Waiver of Claims prohibits Executive from reporting possible violations of federal law or regulation to any governmental agency or entity, including but not limited to the Department of Justice, the Securities and Exchange Commission, the Congress, and any agency Inspector General, or making other disclosures that are protected under the whistleblower provisions of federal law or regulation. Executive does not need the prior authorization of the Company to make any such reports or disclosures and Executive is not required to notify the Company that Executive has made such reports or disclosures.

6.              Affirmations. Employee affirms Executive has not filed, has not caused to be filed, and is not presently a party to, any claim, complaint, or action against Employer in any forum. Employee further affirms that the Executive has been paid and/or has received all compensation, wages, bonuses, commissions, and/or benefits to which Executive may be entitled and no other compensation, wages, bonuses, commissions and/or benefits are due to Executive, except as provided in Section 8 of the Employment Agreement. Employee also affirms Executive has no known workplace injuries.

7.              Cooperation; Return of Property. Employee agrees to reasonably cooperate with Employer and its counsel in connection with any investigation, administrative proceeding or litigation relating to any matter that occurred during Executive’s employment in which Executive was involved or of which Executive has knowledge. Employer will reimburse the Employee for any reasonable out-of-pocket travel, delivery or similar expenses incurred in providing such service to Employer. Employee represents that Employee has returned to Employer all property belonging to Employer, including but not limited to any leased vehicle, laptop, cell phone, keys, access cards, phone cards and credit cards, provided that Executive may retain, and Employer shall cooperate in transferring, Executive’s cell phone number and Executive’s personal rolodex and other address books.

8.              Governing Law and Interpretation. This Agreement and General Release shall be governed and conformed in accordance with the laws of the Commonwealth of Massachusetts without regard to its conflict of laws provisions. In the event Employee or Employer breaches any provision of this Agreement and General Release, Employee and Employer affirm either may institute an action to specifically enforce any term or terms of this Agreement and General Release. Should any provision of this Agreement and General Release be declared illegal or unenforceable by any court of competent jurisdiction and should the provision be incapable of being modified to be enforceable, such provision shall immediately become null and void, leaving the remainder of this Agreement and General Release in full force and effect. Nothing herein, however, shall operate to void or nullify any general release language contained in the Agreement and General Release.

9.              No Admission of Wrongdoing. Employee agrees neither this Agreement and General Release nor the furnishing of the consideration for this Agreement and General Release shall be deemed or construed at any time for any purpose as an admission by Employer of any liability or unlawful conduct of any kind.

10.           Non-Disparagement. Employee and Employer (through its officers and directors) agree not to disparage the other party, and the other party’s officers, directors, employees, shareholders and agents, in any manner likely to be harmful to them or their business, business reputation or personal reputation; provided that both Employee and Employer may respond accurately and fully to any question, inquiry or request for information when required by legal process and provided further that nothing in this Section 10 shall preclude Employer or Employee from making truthful statements that are reasonably necessary or to enforce or defend the party’s rights under this Agreement and General Release.

11.           Amendment. This Agreement and General Release may not be modified, altered or changed except upon express written consent of both parties wherein specific reference is made to this Agreement and General Release.

12.           Entire Agreement. This Agreement and General Release and the Confidentiality Agreement (as defined in the Employment Agreement) sets forth the entire agreement between the parties hereto and fully supersedes any prior agreements or understandings between the parties; provided, however, that notwithstanding anything in this Agreement and General Release, the provisions in the Employment Agreement which are intended to survive termination of the Employment Agreement, including but not limited to those contained in Section 10 thereof, shall survive and continue in full force and effect. Employee acknowledges Executive has not relied on any representations, promises, or agreements of any kind made to Executive in connection with Executive’s decision to accept this Agreement and General Release.

13.           ADEA. Employee understands and acknowledges that Employee is waiving and releasing any rights Executive may have under the Age Discrimination in Employment Act of 1967 (“ADEA”), and that this waiver and release is knowing and voluntary. Employee understands and agrees that this waiver and release does not apply to any rights or claims that may arise under the ADEA after the date Executive signs this Agreement and General Release. Employee understands and acknowledges that the consideration given for this waiver and release is in addition to anything of value to which Employee was already entitled. Employee further understands and acknowledges that Employee has been advised by this writing that nothing in this Agreement prevents or precludes Executive from challenging or seeking a determination in good faith of the validity of this waiver under the ADEA, nor does it impose any condition precedent, penalties, or costs for doing so, unless specifically authorized by federal law.
