Agreement by the Company Principal Stockholder and the consummation by Company
Principal Stockholder of the transactions contemplated hereby.

       

      
        
           

        

        
          3

          
            

          

        

        
           

        

      

    

    


    5.           Covenants of Company
Principal Stockholder.   The Company

Agreement;

    

     

    
      (b)           acquire
any shares of the stock of Parent except pursuant to existing Company Options

      (c)           grant
any powers of attorney or proxies or consents in respect of any of the Subject

voting agreement with respect to any of such Subject Shares;
or

    

     

    
      (d)           take
any other action with respect to the Subject Shares that would in any way
restrict, limit or interfere with the performance of Company Principal

the Merger Agreement.

    

     

    
      6.           Adjustments; Additional

recapitalization, reclassification, combination, exchange of shares or the like
of the capital stock of the Company on, of or affecting the Subject Shares, or
(b) that Company Principal Stockholder shall become the Beneficial Owner of
any additional shares of Company Capital Stock or other securities entitling the
holder thereof to vote or give consent with respect to the matters set forth in

Company Capital Stock or other instruments or documents held by Company
Principal Stockholder immediately following the effectiveness of the events
described in clause (a) or Company Principal Stockholder becoming the
Beneficial Owner thereof as described in clause (b), as though, in either
case, they were Subject Shares hereunder.

    

     

    
      7.           Amendments and
Waivers.
  Any provision of this Agreement may be amended or waived if, and
only if, such amendment or waiver is in writing and is signed, in the case of an
amendment, by each party to this Agreement, or in the case of a waiver, by the
party against whom the waiver is to be effective. No failure or delay by any
party in exercising any right or privilege hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise thereof preclude any other or
further exercise thereof or the exercise of any other right, power or privilege.
To the maximum extent permitted by law, (a) no waiver that may be given by
a party shall be applicable except in the specific instance for which it was
given and (b) no notice to or demand on one party shall be deemed to be a
waiver of any obligation of such party or the right of the party giving such
notice or demand to take further action without notice or
demand.

    

     

    
      8.           Assignment.   This Agreement
may not be assigned by any party hereto without the prior written consent of the
other parties. Subject to the foregoing, all of the terms and provisions of this
Agreement shall inure to the benefit of and be binding upon the parties hereto
and their respective executors, heirs, personal representatives, successors and
assigns.

    

     

    
      9.           Entire Agreement.   This Agreement
and the documents, instruments and other agreements specifically referred to
herein or delivered pursuant hereto, set forth the entire understanding of the
parties with respect to the subject matter hereof. Any and all previous
agreements and understandings between or among the parties regarding the subject
matter hereof, whether written or oral, are superseded by this
Agreement.

      12. 
Severability;
Enforcement.
  Any provision of this Agreement which is invalid or unenforceable in
any jurisdiction shall be ineffective to the extent of such invalidity or
unenforceability without invalidating or rendering unenforceable the remaining
provisions hereof, and any such invalidity or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

    

     

    
      13. 
Specific
Performance.
  The Company Principal Stockholder acknowledges that the agreements
contained in this Agreement are an integral part of the transactions
contemplated by the Merger Agreement, and that, without these agreements, Parent
would not enter into the Merger Agreement, and acknowledges that damages would
be an inadequate remedy for any breach by the Company Principal Stockholder of
the provisions of this Agreement.  Accordingly, the Company Principal
Stockholder agrees that his obligations hereunder shall be specifically
enforceable and he shall not take any action to impede the other from seeking to
enforce such right of specific performance.

    

     

    
      14. 
Consent to
Jurisdiction.
  Each party irrevocably submits to the exclusive jurisdiction of
(a) New York County, New York, and (b) the United States District
Court for the Southern District of New York, for the purposes of any action,
suit or proceeding arising out of this Agreement or any transaction contemplated
hereby. Each party agrees to commence any such action, suit or proceeding either
in the United States District Court for the Southern District of New York or if
such action, suit or proceeding may not be brought in such court for
jurisdictional reasons, in the Supreme Court sitting in New York County
(including its Appellate Division).  Each party further agrees that
service of any process, summons, notice or document by U.S. registered mail
to such party’s respective address set forth above shall be effective service of
process for any action, suit or proceeding in New York with respect to any
matters to which it has submitted to jurisdiction in this
Section 14.  Each party irrevocably and unconditionally waives
any objection to the laying of venue of any action, suit or proceeding arising
out of this Agreement or the transactions contemplated hereby in (i) the
United States District Court for the Southern District of New York, or
(ii) the Supreme Court sitting in New York County (including its Appellate
Division), and hereby further irrevocably and unconditionally waives and agrees
not to plead or claim in any such court that any such action, suit or proceeding
brought in any such court has been brought in an inconvenient forum. EACH PARTY
HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION (WHETHER
BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS
AGREEMENT OR THE ACTIONS OF SUCH PARTY IN THE NEGOTIATION, ADMINISTRATION,
PERFORMANCE AND ENFORCEMENT HEREOF.

    

     

    
      15. 
Governing
Law.
  This Agreement shall be governed by and interpreted and enforced in
accordance with the laws of the State of New York, without giving effect to any
choice of law or conflict of laws rules or provisions (whether of the State of
New York or any other jurisdiction) that would cause the application of the laws
of any jurisdiction other than the State of New York, except to the extent that
the voting of the Subject Shares is subject to the corporate law of the State of
Delaware.
