customer and vendor relationships, and goodwill.

Agreement, his experiences and capabilities are such that he can obtain gainful employment without violating this Agreement, in a business engaged in other lines and/or of a different nature, without his incurring undue hardship; and (ii) the
enforcement of a remedy under this Section 6 by way of injunction will not prevent the him from earning a livelihood.

 f. Injunctive Relief. The parties hereto may seek
injunctive relief in arbitration; provided, however, that as an exception to the arbitration agreement set forth this Section 7.2, the Parties, in addition to all other available remedies, shall each have the right to initiate an action in any
court of competent jurisdiction in order to request injunctive or other equitable relief regarding the terms of this Agreement. The exclusive venue of any such proceeding shall be in the Agreed Venue. The Parties agree (i) to submit to the
jurisdiction of any competent court in the Agreed Venue, (ii) to waive any and all defenses the Executive may have on the grounds of lack of jurisdiction of such court and (iii) that neither Party shall be required to post any bond,
undertaking or other financial deposit or guarantee in seeking or obtaining such equitable relief. Evidence adduced in any such proceeding for an injunction may be used in arbitration as well. The existence of this right shall not preclude or
otherwise limit the applicability or exercise of any other rights and remedies that a Party may have at law or in equity.

immediately upon written notice of termination to the Employee, upon the Employee’s Disability or for Cause. [Note: With the 30-day-notice-termination provision in Section 2, these provisions are, and the Disability provision
particularly is, of only limited application.] In this Agreement: 
  
 a. “Disability” means the Employee’s becoming incapacitated by accident, sickness, or other circumstances that, in the reasonable judgment of the Board [or the CEO?], renders or is expected to render the

 10 








 b. “Cause” means any of the following: 
  

	 	i.	the Company’s determination that the Employee has neglected, failed, or refused to render the services or perform any other of his duties or obligations in or under this

	 	ii.	the Employee’s violation of any provision of or obligation under this Agreement; 

  

	 	iii.	the Employee’s indictment for, or entry of a plea of no contest with respect to, any crime that adversely affects or (in the Board’s reasonable judgment) may adversely
affect the Company or the utility of the Employee’s services to the Company; or 

  

	 	iv.	any other act or omission of the Employee involving fraud, theft, dishonesty, disloyalty, or illegality with respect to, or that harms or embarrasses or (in the Board’s
reasonable judgment) may harm or embarrass, the Company or any of its subsidiaries, affiliates, customers, dealers or suppliers. 

  
 8.2 Effects of Termination. Upon any cessation or termination of employment under this Agreement, all further rights of the Employee to
employment and compensation and benefits from the Company under this Agreement will cease, except that the Company shall pay the Employee the following: 
  
 a. Any amount of base salary earned by, but not yet paid to, the Employee through the last date of the Employment Period (the “Termination
Date”); 
  
 b. Any annual bonus, or portion thereof, that
the Compensation Committee may deem to be earned by, but not yet paid to, the Employee through the Termination Date; 
  
 c. All reimbursable expenses due, or but not paid, to the Employee as of the Termination Date in accordance with Section 3.4 hereof; 
  
 d. All benefits (or an amount equivalent thereto) that have been earned by or
vested in, and are payable to, the Employee under, and subject to the terms of, the employee-benefit plans or arrangements of the Company in which the Employee participated through the Termination Date in accordance with Section 3.5 hereof; and

  
 e. An amount equal to all accrued and unused vacation,
calculated in accordance with the Company’s vacation policies, practices, and procedures, through the Termination Date in accordance with Section 3.7 hereof. 
  
 Any amount due under clause b. above in this Section 8.2 shall be paid in the same manner and on the same date as would have occurred
if the Employee’s employment under this Agreement had not ceased. Any amount due under clause d. above in this Section 8.2 shall be paid in accordance with the terms of the employee-benefit plans or arrangements under which such amounts
are due to the Employee. The amounts due under clause c. and clause e. of this Section 8.2 shall be paid in accordance with the terms of the Company’s policies, practices, and procedures regarding reimbursable expenses and vacation,
respectively. Except for the payment of such amounts when due, the Company shall have no further obligation or liability under this Agreement for any other compensation, payment, or benefit to the Employee. The stock option agreements between the
Parties and the Plan shall govern the Employee’s outstanding stock options upon or after cessation or termination of employment. Also upon cessation or termination of employment hereunder (unless the Employee continues otherwise to be employed
by the Company), the Employee (1) shall return to the Company the leased vehicle provided for the Employee’s use in accordance with Section 3.6 hereof, and (2) shall resign or shall be deemed to have resigned from any position as
an officer or director, or both, of any subsidiary or affiliate of the Company.

his other activities, to provide such information as may from time to time be requested by the Company regarding various matters in which he was involved during his employment with the Company, and (b) any and all pending or future litigation
or administrative claims, investigations, or proceedings involving the Company, including (without limitation) his meeting with the Company’s counsel and advisors at reasonable times upon their request and providing testimony (in court or
arbitration hearing or at depositions) that is truthful, and complete in accordance with information known to him. 
  
 SECTION 9. 
 NON-DISPARAGEMENT AND MEDIA NON-DISCLOSURE

Employment Period or at any time thereafter, the Employee will not make any statements, comments or communications in any form, oral, written or electronic, to any Media or any customer, client or supplier of the Company or any of its or any of its
directors, officers, shareholders, or affiliates, which (a) would constitute libel, slander or disparagement of the Company or any of its directors, officers, shareholders, or affiliates, including, without limitation, any such statements,
comments or communications that criticize, ridicule or are derogatory to the Company or any of its directors, officers, shareholders, or affiliates; or (b) may be considered to be derogatory or detrimental to the good name or business
reputation of the Company, or any of its directors, officers, shareholders, or affiliates; provided however, that the terms of this Section 9.1 shall not apply to communications between the Employee and, as applicable, the Employee’s
attorneys or other Persons with whom or which communications would be subject to a claim of privilege existing under common law, statute or rule of procedure. The Employee further agrees that he will not in any way solicit any such statements,
comments or communications from others.

 11.7 Amendment; Waiver. No amendment to or modification of this Agreement, or waiver
of any term, provision, or condition of this Agreement, will be binding upon a Party unless the amendment, modification, or waiver is in writing and signed by the Party to be bound. Any waiver by a Party of a breach or violation of any provision of
this Agreement by the other Party shall not be deemed a waiver of any other provision or of any subsequent breach or violation. 
  
 11.8 Enforcement and Severability. The Parties intend all provisions of this Agreement to be enforced to the fullest extent permitted by
law. Accordingly, should an arbitrator or a court of competent jurisdiction determine that the scope of any provision of this Agreement is too broad to be enforced as written, the Parties intend for the arbitrator or the court to reform the
provision to such narrower scope as it determines to be reasonable and enforceable. If, however, any provision of this Agreement is held to be illegal, invalid, or unenforceable, the provision shall be severed, this Agreement shall be construed and
enforced as if such illegal, invalid, or unenforceable provision were never a part of it, and the remaining provisions shall remain in full force and effect.

grant rights to Employee for employment or compensation for such period. The Section and other descriptive headings in this Agreement are only for convenience of reference and are not to be used to construe or interpret this Agreement or any of its
provisions.
