and between Neoteris, Inc., a Delaware corporation (the “Company”), and Stockholder (the “Stock Agreement”) and the (b) Amended and Restated Employment Agreement dated April 19, 2001 by and between the

 WHEREAS, the Company, Acquirer and Neon Acquisition Corp., a Delaware corporation and wholly owned subsidiary of Acquirer (“Merger Sub”), have entered into that certain Agreement and Plan of Merger
dated October 3, 2003 (the “Merger Agreement”) providing for the merger of Merger Sub with the Company (the “Merger”); and 
  
 WHEREAS, at the effective time of the merger of Merger Sub with the Company as defined in the Merger Agreement (the
“Effective Time”) Stockholder shall commence employment with Acquirer pursuant to the assumption of the Employment Agreement and in connection therewith Stockholder and Acquirer have entered into that certain Assumption and
Amendment Agreement that modifies the Employment Agreement (the Employment Agreement, as amended by the Amendment and Assumption Agreement, is referred to as the “Assumed Employment Agreement”). 
  
 NOW, THEREFORE, in consideration of the
foregoing and the mutual promises, covenants and conditions contained herein, the parties hereby agree as follows: 
  
 1 Acknowledgments and Waivers by Stockholder. 
  
 (a) Stockholder hereby acknowledges and agrees that the commencement of Stockholder’s employment with Acquirer Employer, on the terms and conditions
of the Assumed Employment Agreement, shall not constitute (i) a termination of Stockholder’s employment for “Good Reason” (as defined in Section 5.5(b) of the Employment Agreement), (ii) a termination of Stockholder’s employment
pursuant to Section 3(a)(iv) of the Stock Agreement, or (iii) any other type of “constructive termination” as such term is generally understood, and Stockholder hereby waives the provisions of Section 5.5(b) of the Employment Agreement
and/or the provisions of Section 3(a)(iv) of the Stock Agreement with respect to the Merger and with respect to any termination by Stockholder whether or not in connection with a change of control of the Company, Acquirer Employer or Acquirer.








 (b) Stockholder hereby waives any rights to accelerated vesting and/or accelerated exercisability, as
applicable, of Stockholder’s stock or options pursuant to the Compensation Arrangement arising as a result of the Merger or arising in connection with Stockholder’s employment with Acquirer Employer. 
  
 (c) Stockholder hereby acknowledges that, subject to and on the terms and
conditions of the Merger Agreement, as a result of the Merger Acquirer is assuming all of Stockholder’s options to purchase shares of the Company’s common stock and that Stockholder’s stock shall remain subject to its original vesting
schedule and that Acquirer will succeed to the Company’s right to repurchase Stockholder’s unvested stock on the terms and conditions of the Stock Agreement. Stockholder hereby acknowledges and agrees that none of Stockholder’s stock
or options shall automatically vest or accelerate as a result of the Merger and the transactions contemplated thereby and/or as a result of the assumption of Stockholder’s options or the assignment to Acquirer of the Company’s rights to
repurchase unvested stock as provided in the Merger Agreement. Stockholder hereby waives any rights to automatic vesting or acceleration of Stockholder’s stock or options upon or following the Merger. 
  
 2. Agreements by Acquirer. 
  
 (a) Notwithstanding the provisions of Section 1 or any other provision of
the Compensation Arrangement, subject to execution of the general release required under the first paragraph of Section 5.3 of the Assumed Employment Agreement, Acquirer hereby agrees that, upon termination of Stockholder by Acquirer Employer
without Cause (as defined in the Employment Agreement) or Stockholder’s voluntary termination for Good Reason (as defined in the Employment Agreement) within twenty-four (24) months following the Effective Time of the Merger, Stockholder shall
receive twenty-four (24) months of accelerated vesting and/or accelerated exercisability of Stockholder’s stock and options, as applicable, issued or issuable under the Stock Agreement and/or the Option Agreement; provided,
however, that Stockholder’s options under the Option Agreement, if any, shall remain exercisable only until the earlier of (i) the Expiration Date (as defined in the Option Agreement) and (ii) the date on which Stockholder’s options
under the Option Agreement would otherwise terminate following a termination without Cause (as defined in the Employment Agreement). A transfer of Stockholder from one Acquirer Employer to another Acquirer Employer shall not be construed as a
termination of Stockholder. A voluntary termination by the Stockholder shall not trigger any acceleration of vesting and/or accelerated exercisability of the Stockholder’s stock or options, except where such voluntary termination by the
Stockholder is for Good Reason (as defined in the Employment Agreement). 
  
 (b) Notwithstanding the foregoing, Stockholder shall not be entitled to any accelerated vesting and/or exercisability of the Stockholder’s stock or options, as applicable, if Stockholder’s employment is
terminated by Acquirer Employer for Cause (as defined in the Employment Agreement).
