 (c)
Options. 
 (i) The Company shall grant to the Executive an option to purchase 100,000 shares of the

4. Compensation Upon Termination, Resignation, Disability or Death. 

(a) Termination without Cause. If the Executive’s employment is terminated by the Company without Cause, the
Company shall pay the Executive any Base Salary and Annual Bonus from the preceding calendar year to the extent accrued but unpaid as of the effective date of the Executive’s termination; accrued but unused vacation in accordance with Company
policy; and all business expenses that were incurred and not reimbursed but eligible for reimbursement (collectively, the “Accrued Obligations”). In addition, the Executive will be entitled to a prorated amount of the current
calendar year Annual Bonus, with payment of such prorated Annual Bonus to be made at the same time as annual bonuses are made to other executives of the Company in the ordinary course (but in no event later than March 15th of the calendar year

Executive’s dependents, that the Company paid immediately prior to the date of termination, during the twelve (12) month period following the date of termination, subject to the Executive’s continued eligibility for COBRA coverage.
The Company will pay for such COBRA coverage for eligible dependents only for those dependents who were enrolled immediately prior to the date of termination. The Executive will continue to be required to pay that portion of the premium for the
Executive’s health coverage, including coverage for the Executive’s eligible dependents, that the Executive was required to pay as an active employee immediately prior to the date of termination. Notwithstanding the foregoing, in the event
that under applicable guidance the reimbursement of COBRA premiums causes the Company’s group health plan to violate any applicable nondiscrimination rule, the parties agree to negotiate in good faith a mutually agreeable alternative
arrangement. Upon termination under this Section 4(a), (i) the Stock Options shall cease vesting and (ii) all vested Stock Options shall remain exercisable until the earlier of (x) the date one hundred eighty (180) calendar days

 (d) The Executive acknowledges that any breach of his obligations under this
Section 5 cannot be adequately compensated by damages in an action at law and may cause the Company great and irreparable injury and damage. Accordingly, in the event that the Executive breaches or threatens to breach any provisions of this
Section 5, then in addition to any other rights which the Company may have, the Company shall be entitled, without the necessity of (i) proving irreparable harm, (ii) establishing that monetary damages are inadequate or

Section 5 shall be effective shall be computed by excluding from such computation any time during which the Executive is in violation of any provision of this Section 5. 

(f) The Company and the Executive agree that it was their intent to enter into a valid and enforceable agreement. The
Executive and the Company thereby acknowledge the reasonableness of the restrictions set forth in this Section 5, including the reasonableness of the duration as to time and the scope of activity restrained. The Executive agrees that if any covenant
contained in Section 5 of this Agreement is found by a court of competent jurisdiction to contain limitations as to time or scope of activity that are not reasonable and impose a greater restraint than is necessary to protect the goodwill or
other business interests of the Company, then the court shall reform the covenant to the extent necessary to cause the limitations contained in the covenant as to time and scope of activity to be restrained to be reasonable and to impose a restraint
that is not greater than necessary to protect the goodwill and other business interests of the Company and to enforce the covenants as reformed. 
 (g) If the Executive’s employment with the Company is terminated for any reason, the Executive agrees to advise the Company of the name of the Executive’s new employer. The Executive further
agrees that the Company may notify any person or entity employing the Executive or evidencing an intention of employing the Executive of the existence and provisions of this Agreement.

(a) above. The Executive shall provide 30 days’ prior written notice to the Company of his decision to resign for Good Reason. 
 (c) Termination for Cause. If the Executive’s employment is terminated by the Company for Cause, the Company shall pay the Executive the Accrued Obligations. Upon termination under this

fifteen (15) calendar day period. 
 (ii) “Good Reason” means: (a) a material
diminution in the Executive’s Base Salary, except where such reduction occurs as part of an across-the-board reduction in salary affecting all senior executives of the Company; or (b) any other action or inaction by the Company that

automatic resignation of the Executive from the board of directors or similar governing body of the Company or any affiliate of the Company and from the board of directors or 

  
 5

confidential or non-public because of any duty of confidentiality owed by the Company to a third party; and (iii) any other information which the Company shall, in the ordinary course, use and not release externally, except subject to
restrictions on use and disclosure. Notwithstanding the foregoing, Confidential Information does not include information that (A) is or becomes generally publicly available other than as a result, directly or indirectly, of the Executive’s
disclosure or (B) is or becomes available to the Executive on a non-confidential basis from a source other than through the Company or its representatives, provided that such source is not bound by a confidentiality agreement with the Company
or otherwise prohibited from transmitting the information to the Executive by a contractual or legal obligation. 

(b) The Executive acknowledges the trade secret status of the Confidential Information and that the Confidential
Information constitutes a protectable business interest of the Company. The Executive agrees (i) not to use or allow or help another to use or access (whether for compensation or not) any Confidential Information for himself or others (other
than the Company); and (ii) not to take any Company material or reproductions (including but not limited to writings, correspondence, notes, drafts, records, invoices, technical and business policies, computer programs or disks) thereof from
the Company’s offices at any time during or after the Executive’s employment by the Company, except as required in the execution of the Executive’s duties to the Company and then conditioned upon the prompt return of all originals and
reproductions thereof (in whatever form). 
 (c) During the Term and for a period of one (1) year
thereafter, the Executive shall not, directly or indirectly, on behalf of himself or any other person or entity, without 

  
 6 

 
the prior written consent of the Company solicit or induce any employee of or consultant or service provider to the Company (each, a “Service Provider”) to leave the employ of or
cease performing services for the Company, or engage in any plan or coordinate with any Service Provider to leave the employ of or cease performing services for the Company, or hire, participate with or attempt to participate with in any venture for
any purpose any Service Provider or any Service Provider who has left the employment of or ceased to perform services for the Company within one year of the termination of such Service Provider’s services for the Company. 

(d) The Executive acknowledges that any breach of his obligations under this Section 5 cannot be adequately
compensated by damages in an action at law and may cause the Company great and irreparable injury and damage. Accordingly, in the event that the Executive breaches or threatens to breach any provisions of this Section 5, then in addition to any
other rights which the Company may have, the Company shall be entitled, without the necessity of (i) proving irreparable harm, (ii) establishing that monetary damages are inadequate or (iii) posting any bond or other security with
respect thereto, to the remedies of injunction, specific performance and other equitable relief to redress any breach, and no proof of special damages shall be necessary for the enforcement of or for any action for breach of the Executive’s
obligations. In the event that a proceeding is brought in equity to enforce the provisions of this Section 5, the Executive shall not urge as a defense that there is an adequate remedy at law nor shall the Company be prevented from seeking any
other remedies which may be available. Nothing contained in this Section 5(d) shall be construed as a waiver by the Company of any other rights, including, without limitation, rights to damages or profits. 

(e) The Executive agrees that the period during which the covenants contained in this Section 5 shall be effective
shall be computed by excluding from such computation any time during which the Executive is in violation of any provision of this Section 5. 
 (f) The Company and the Executive agree that it was their intent to enter into a valid and enforceable agreement. The Executive and the Company thereby acknowledge the reasonableness of the restrictions
set forth in this Section 5, including the reasonableness of the duration as to time and the scope of activity restrained. The Executive agrees that if any covenant contained in Section 5 of this Agreement is found by a court of competent
jurisdiction to contain limitations as to time or scope of activity that are not reasonable and impose a greater restraint than is necessary to protect the goodwill or other business interests of the Company, then the court shall reform the covenant
to the extent necessary to cause the limitations contained in the covenant as to time and scope of activity to be restrained to be reasonable and to impose a restraint that is not greater than necessary to protect the goodwill and other business
interests of the Company and to enforce the covenants as reformed. 
 (g) If the Executive’s employment with
the Company is terminated for any reason, the Executive agrees to advise the Company of the name of the Executive’s new employer. The Executive further agrees that the Company may notify any person or entity employing the Executive or
evidencing an intention of employing the Executive of the existence and provisions of this Agreement.
