Any unpaid, accrued salary, bonuses and expense reimbursements should be paid within thirty (30) days of the date of termination and no later than the March 15th after the calendar year of the termination of employment of the Executive under subparagraph (i), (ii) or (v) of paragraph 6(a).

entitled to receive an amount equal to twelve (12) months of Base Salary plus a bonus incentive equal to the target bonus set forth in the Executive’s bonus plan in effect as of the Termination Date as if such targets had been achieved. At
the discretion of the Corporation (except if the Executive elects to receive monthly installments), (i) such Base Salary may be paid either in one lump sum or in monthly installments throughout the remaining term of this Agreement, and
(ii) such bonus incentive amount may be paid either in one lump sum or in monthly installments for up to twenty four (24) months from the Termination Date, provided that reference is made to the limitations in Section 6(k) below and
that for (i) or (ii), monthly installments may only be selected if they would not trigger a taxable event under Section 409A of the Code. 
 (d) Upon termination pursuant to subparagraph (a) (iii)(C) above, the Executive shall be entitled to receive an amount equal to eighteen (18) months of Base Salary plus a bonus incentive equal to the target bonus set forth in the
Executive’s bonus plan in effect as of the Termination Date as if such targets had been achieved. At the discretion of the Corporation (except if the Executive elects to receive monthly installments), (i) such Base Salary may be paid

Code. 
 The commencement of the cash payout will be governed by a standard “double trigger” mechanism approved by the Board and
will commence upon the occurrence of the second trigger (defined below), provided further that if such second trigger does not occur no cash payout shall be due hereunder. The first “trigger” is the “Change of Control” event and
the “second trigger” is the earliest of the following: 
 (i) the Executive is not offered prior to the Change in Control (1) a

Executive as in effect on the Termination Date. Notwithstanding the foregoing, nothing in this Section 6(e) shall be construed to affect the Executive’s right to receive COBRA continuation entirely at the Executive’s own cost to the
extent that the Executive may continue to be entitled to COBRA continuation after the Executive’s right to cost sharing under this Section 6(e) ceases, provided further the continued health benefits provided hereunder shall supplement, and
not in any manner be construed to replace or otherwise limit, the periods of COBRA continuation that the Executive would have otherwise been entitled to. 
 (f) Upon termination pursuant to subparagraph (iv) above, the Executive shall be entitled to receive an amount equal to twelve (12) months of Base Salary plus a bonus incentive equal to the target bonus set
forth in the Executive’s bonus plan in effect as of the Termination Date as if such targets had been achieved. At the discretion of the Corporation (except if the Executive elects to receive monthly installments), (i) such Base Salary may
be paid either in one lump sum or in monthly installments throughout the remaining term of this Agreement, and (ii) such bonus incentive amount may be paid either in one lump sum or in monthly installments for up to twenty four (24)

  

 5

installments may only be selected if they would not trigger a taxable event under Section 409A of the Code. 
 In addition, upon
termination pursuant to subparagraph (iv) above, the Corporation shall provide continuation of health benefits for a period equal to the longer of (a) the remainder of the term of this Agreement, or (b) twelve (12) months from
the Termination Date to the extent authorized by and consistent with 29 U.S.C. § 1161 et seq. (commonly known as “COBRA”), with the cost of the regular premium for such benefit shared in the same relative proportion by the Corporation
and the Executive as in effect on the Termination Date. Notwithstanding the foregoing, nothing in this Section 6(f) shall be construed to affect the Executive’s right to receive COBRA continuation entirely at the Executive’s own cost
to the extent that the Executive may continue to be entitled to COBRA continuation after the Executive’s right to cost sharing under this Section 6(f) ceases, provided further the continued health benefits provided hereunder shall
supplement, and not in any manner be construed to replace or otherwise limit, the periods of COBRA continuation that the Executive would have otherwise been entitled to. 
 (g) For purposes of this Agreement, a “Change in Control of the Corporation” shall be deemed to have occurred upon any one of the following events: 
  

	 	(i)	The date on which shares of Common Stock are first purchased pursuant to a tender offer or exchange offer (other than such an offer by the Corporation, any Subsidiary, any employee

of the number of shares purchased pursuant to such offer; 

  

	 	(ii)	The date the Corporation acquires knowledge that any person or group deemed a person under Section 13(d)-3 of the Securities Exchange Act of 1934 (“Exchange Act”)

individual or entity or group or affiliate thereof which acquired its beneficial ownership interest prior to the date of this Agreement), in a transaction or series of transactions, has become the beneficial owner, directly or indirectly (with
beneficial ownership determined as provided in Rule 13d-3, or any successor rule, under the Exchange Act), of securities of the Corporation entitling the person or group to 30% or more of all votes (without consideration of the rights of any class
or stock to elect directors by a separate class vote) to which all stockholders of the Corporation would be entitled in the election of the Board of Directors were an election held on such date; 

  

	 	(iii)	The date, during any period of two consecutive years, when individuals who at the beginning of such period constitute the Board of Directors of the Corporation cease for any reason
to constitute at least a majority thereof, unless the election, or the nomination for election by the stockholders of the Corporation, of each new director was approved by a vote of at least two-thirds of the directors then still in office who were
directors at the beginning of such period; and 

  

	 	(iv)	The date of approval by the stockholders of the Corporation of an agreement (a “reorganization agreement”) providing for:

beneficially own, immediately after the merger or consolidation, shares of the corporation issuing cash or securities in the merger or consolidation entitling such stockholders to 65% or more of all votes (without consideration of the rights of any
class of stock to elect directors by a separate class vote) to which all stockholders of such corporation would be entitled in the election of directors or where the members of the Board of Directors of the Corporation, immediately prior to the
merger or consolidation, do not, immediately after the merger or consolidation, constitute a majority of the Board of Directors of the corporation issuing cash or securities in the merger or consolidation; or 

  

 6 









	 	(B)	The sale or other disposition of all or substantially all the assets of the Corporation.

Executive whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise (the “Payments”), the Executive would be subject to the excise tax imposed by Section 4999 of the Internal Revenue
Code (the “Code”) or any interest or penalties are incurred by the Executive with respect to such excise tax (such excise tax, together with any such interest and penalties, are hereinafter collectively referred to as the “Excise
Tax”), the Executive shall be entitled to promptly receive an additional payment (a “Gross-Up Payment”) in an amount such that, after payment by the Executive of all taxes (including any interest or penalties imposed with respect to
such taxes), including, without limitation, any income taxes and Excise Tax imposed upon the Gross-Up Payment, the Executive is in the same after-tax position as if no Excise Tax had been imposed upon the Executive with respect to the Payments,
provided further that such Gross-Up Payment shall not exceed $500,000 under any circumstances. 
 Notwithstanding the above provisions of
this Section (h), the Executive’s Payments, shall be reduced to an amount (not less than zero) which shall not cause any portion of the Payments to be subject to Excise Tax, provided that no such reduction shall be made if the Executive’s
Payments, after the reduction and after the application of Federal income tax at the highest rate applicable to individual taxpayers, shall not be greater than the present value (determined in accordance with Section 280G of the Code) of the
Payments and any applicable Gross-Up Payment before the reduction but after the application of (i) excise tax under Section 4999 of the Code and (ii) Federal income tax at the highest rate applicable to individual taxpayers.

 (i) Cooperation: Pending Litigation 
  

	 	(i)	Upon the request of the Corporation, in connection with any suit, action, proceeding, arbitration or litigation involving the Corporation (a “Litigation”), which
Litigation is directly or indirectly the result of an event, fact or occurrence existing, in whole or in part, prior to the Termination Date, Executive agrees to, at the expense of the Corporation, in connection with any such Litigation:

amended, as of the date of his separation from service for any reason, then the payment dates hereunder shall be adjusted so that no payment of deferred compensation hereunder that is subject to §409A may be made before the expiration of six
(6) months after the date of the Executive’s separation from service, or if earlier, the Executive’s death. 
 (k)
Notwithstanding anything herein to the contrary contained herein, with regards to the determination of lump sum or monthly installment payments to be made under Sections 6(c), (d) and (f) above, the Board shall determine the form of
