considered, researched, developed, marketed and/or sold at the time of termination; provided, however, that the holding by the Executive of any investment in any security shall not be deemed to be a violation of this section 

  

 6 

 
if such investment does not constitute over one percent (1%) of the outstanding issue of such security. The restriction shall run for a period of one
year after said termination, and if there shall be any violation hereof during said period, then for a period of one year after cessation of such violation.

 7 

 
both qualified and willing to seek and obtain employment involving business activities which will not violate any covenant on his part to be observed
hereunder and that a court decree enjoining any such violation will not prevent him from earning a reasonable livelihood.

compensation for the duties under this paragraph is included in the salary and benefits provided herein. 
 E) If the Executive is terminated
as a result of a Change of Control, as defined in this Agreement, this Section, titled “Covenant Not to Compete,” shall not be applicable. 
 F) The parties agree that if any provision of this Section 8 is held invalid or unenforceable by a court of competent jurisdiction, that part should be modified by the court to make it enforceable to the maximum
extent possible. If the part cannot be modified, then that part may be severed and the other parts of this Agreement shall remain enforceable.

heard by the Board of the Company, finding that in the good faith opinion of the Board of the Company the Executive was guilty of the conduct set forth and specifying the particulars thereof in detail. 
 F) The Executive’s act, or failure to act, shall be deemed “willful” if the Executive was not acting in good faith or acting without
reasonable belief that the Executive’s action or omission was in the best interests of the Company. Any act or failure to act based on authority given pursuant to a resolution duly adopted by the Board of the Company, or based upon the advice

 G) For purposes of this Agreement, “Disability” shall mean (A) Executive is unable to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment
which can be expected to result in death or can be expected to last for a continuous period of not less than twelve (12) months, or (B) Executive is, by reason of any medically determinable physical or mental impairment which can be

in Control, or any material removal of the Executive from, or any material failure to re-elect the Executive, to any of his previously held positions with the Company, except in connection with the termination of the Executive’s employment for
Cause, Disability or Retirement or as a result of the Executive’s death or by the Executive other than for Good Reason;

Executive at the time of the Change in Control, or the failure by the Company to provide the Executive with the number of paid vacation days to which the Executive is then entitled in accordance with the Company’s normal vacation policy in
effect on the date hereof; or

Control” of the Company shall mean the occurrence of any one of the following events with respect to the Company, but only to the extent each of the following is interpreted in a manner consistent with the meaning of “a change in the
ownership or effective control of the corporation, or in the ownership of a substantial portion of the assets of the corporation” under Section 409A of Internal Revenue Code, as amended, (the “Code 

  

 11 

 
Section 409A”) and any successor statute, regulation and guidance thereto, and limited to the extent necessary so that it will not cause adverse
tax consequences with respect to Code Section 409A: 
 (i) such time as the majority of the members of the BOD is
replaced during any 12-month period (commencing no earlier than the Commencement Date) by directors whose appointment or election is not endorsed by a majority of the members of the BOD prior to the date of appointment or election; 
 (ii) the acquisition by any “Person” (as such term is defined in Section 3(a)(9) of the Securities Exchange Act of 1934
(the “Exchange Act”) and as used in Section 13(d)(3) and 14(d)(2) of the Exchange Act) of the beneficial ownership of any capital stock of the Company if, after such acquisition, such person beneficially owns (within the meaning of
Rule 13d-3 under the Exchange Act) more than 50% of the combined voting power of the Company’s then outstanding securities eligible to vote for the election of the BOD (the “Company Voting Securities”); provided, however, that the
event described in this paragraph (ii) shall not be deemed to be a Change in Control by virtue of any of the following: (a) an acquisition by the Company or any subsidiary of the Company; (b) an acquisition by any employee benefit
plan sponsored or maintained by the Company or subsidiary of the Company; (c) an acquisition by any underwriter temporarily holding securities pursuant to an offering of such securities; or (d) an acquisition by any Person who, prior to

 (iv) the stockholders of the Company
approve a plan of complete liquidation or dissolution of the Company, but only if such approval is in connection with one of the events described in Section 10(A)(i)-(iii) above. 
 B) Notwithstanding the foregoing, a Change in Control of the Company shall not be deemed to occur solely because any Person acquires beneficial ownership
of more than 50% of the Company Voting Securities as a result of the acquisition of Company Voting Securities by the Company which reduces the number of Company Voting Securities outstanding. 
 C) Upon a Change of Control, notwithstanding any other agreement, all stock, restricted stock, stock options or restricted stock options of the Executive
shall become fully vested to 100%.

participate in a similar benefit from another source. All payments shall begin as soon as practicable following the effective date of the separation agreement set forth in Section 11(E) below. 
 C) If the Executive’s employment is terminated by the Company for Disability, or without Cause, if employment terminates because of the
Executive’s death, or if the Executive terminates his employment for Good Reason, then, in addition to the Accrued Obligations, Executive shall be entitled to: (i) salary continuation at the salary the Executive was receiving at the time
of termination for a period of twelve (12) months following termination; and (ii) upon timely election of COBRA continuation coverage, the Executive’s continued participation in any employee health and welfare benefit plan to which
the Executive was a participant prior to 

  

 14 

 
his termination, with the Company premiums paid at the same percentage as when the Executive had participated as an employee, for up to twelve

 D) Notwithstanding any other provision with respect to payments under Section 11(B), if the Executive’s employment is terminated by the Company
within twelve (12) months of a Change of Control for reasons other than Cause, Disability, or his death or if the Executive terminates his employment for Good Reason within twelve (12) months of a Change of Control, then, in lieu of the

health and welfare benefit plan to which the Executive was a participant prior to his termination, with the Company premiums paid at the same percentage as when the Executive had participated as an employee, for up to twenty-four (24) months
following termination; provided that, if COBRA continuation coverage is otherwise earlier terminated under applicable law, then, in lieu of coverage, the Company will pay its share of the monthly Company premium in effect prior to the termination of
COBRA continuation coverage directly to the Executive each month for the remainder of the relevant period. All payments shall begin as soon as practicable following the effective date of the separation agreement set forth in Section 11(E)
below. 
  

 15 

 E) All payments and benefits set forth in Sections 11(B)-(D) are contingent upon the
Executive’s execution (without revocation) of a separation agreement that is in a form acceptable to the Company and contains a full waiver and release of claims against the Company, within twenty-one (21) days of the date such separation
agreement is provided to the Executive. 
 F) Notwithstanding any other provision with respect to the timing of payments under Sections
11(A)-(D), as applicable, if, at the time of the Executive’s termination, the Executive is deemed to be a “specified employee” (within the meaning of Code Section 409 A, and any successor statute, regulation and guidance
thereto) of the Company, then only to the extent necessary to comply with the requirements of Code Section 409A, any payments to which the Executive may become entitled under Sections 11(A)-(D), as applicable, will be withheld until the first
business day of the seventh month following the termination of the Executive’s employment, at which time the Executive shall be paid an aggregate amount equal to six months of payments otherwise due to the Executive under the terms of Sections
11(A)-(D), as applicable. After the first business day of the seventh month following the termination of the Executive’s employment and continuing each month thereafter, the Executive shall be paid the regular monthly payments otherwise due to
the Executive in accordance with the terms of Sections 11(A)-(D), as applicable. In addition, in the event that the Company is obligated to make cash payments directly to the Executive in lieu of COBRA continuation coverage pursuant to the terms of
Section 11(D), then, to the extent necessary to comply with the requirements of Code Section 409A, such cash payments will be withheld, if applicable, in the same manner as described above in this paragraph.

TO A TRIAL BY JURY IN ANY SUCH ACTIONS, SUIT OR PROCEEDING. The Company shall bear all costs associated with the Arbitration, including filing fees and any stipend for the arbitrator. The Company and the Executive shall each bear its own
attorneys’ fees. However, if the Executive prevails in a challenge to the Company’s determination for cause, the Executive shall be entitled to be reimbursed for all attorney fees. 
 B) Nothing in this section shall be read to preclude the Company seeking injunctive relief for the Executive’s breach of Section 7, Proprietary
and Trade Secret Information or Section 8, Covenant Not to Compete. 
  

	13.	Injunctive Relief 

 The Executive
acknowledges that the services rendered by him under this Agreement are of a special, unique and extraordinary character and, in connection with such services, he will have access to confidential information concerning the Company’s business.
By reason of this access to confidential information, the Executive consents and agrees that if he violates any of the provisions of this Agreement with respect to Proprietary and Trade Secret Information or the Covenant Not to Compete, the Company
would sustain irreparable harm and, therefore, in addition to any other remedies which the Company may have under this Agreement or otherwise, the Company shall be entitled to an injunction to be issued by any court of competent jurisdiction
restraining the Executive from committing or continuing to commit any such violation of this Agreement.
