        8.2.    Covenant Not to Sue.    The Executive represents and warrants that he has not filed any complaints, charges,
or claims for relief against the Released Parties with any local, state or federal court or administrative agency. The Executive agrees and covenants not to sue or bring any claims or charges against
the Released Parties with respect to any matters arising out of or relating to the Executive's employment with or separation from the Company, other than enforcement of the terms of this Agreement or
the Indemnification Agreement. In the event that the Executive institutes any such action, that claim shall be dismissed upon presentation of this Agreement and he shall reimburse the Company for all

        9.1.    Time To Consider Agreement.    The Executive acknowledges that he has been advised in writing to consult with
an attorney and has had ample opportunity to consult with and review this Agreement with an attorney of his choice, and has been given a period of at least forty-five (45) days

        10.    Miscellaneous.    


        10.1.    Availability of Equitable Remedies.    The Executive agrees and warrants that the covenants contained herein
are reasonable, that valid consideration has been and will be received therefor and that the agreements set forth herein are the result of arms-length negotiations between the parties
hereto. The Executive recognizes and acknowledges that the provisions of Section 5 are vitally important to the continuing welfare of the Company, and its subsidiaries and affiliates, and that
money damages constitute a totally inadequate remedy for any violation thereof. Accordingly, in the event of any such violation by the Executive, the Company, and its subsidiaries and affiliates, in
addition to any other remedies they may have, shall have the right to institute and maintain a proceeding to compel specific performance thereof or to obtain an injunction restraining any action by
the Executive in violation of Section 5. 


        10.2.    Severability.    In the event that any provision of this Agreement is found by a court, arbitrator or other
tribunal to be illegal, invalid or unenforceable, then such provision shall not be voided, but shall be enforced to the maximum extent permissible under applicable law, and the remainder of this
Agreement shall remain in full force and effect. 


        10.3.    Entire Agreement.    This Agreement and its Exhibits constitutes the entire agreement between the parties
about or relating to the Executive's termination of employment from the Company, or the Company's obligations to the Executive with respect to his termination and fully supersedes any and all prior
agreements or understanding between the parties, other than the Indemification Agreement. 



        10.4.    Binding Benefit.    This agreement shall be binding on the parties and upon their heirs, administrators,
representatives, executors, successors and assigns and shall inure to their benefit and to that of their heirs, administrators, representatives, executors, successors and assigns. 


        10.5.    Amendments.    This Agreement may not be altered, amended or modified, except by a further written document
signed by the Executive and the Company. 


        10.6.    Governing Law.    This Agreement shall be governed by the laws of the Commonwealth of Massachusetts, without
regard to or application of choice-of-law rules or principles. 


        10.7.    Limitations on Recovery.    In the event that the Executive institutes legal proceedings to enforce this
Agreement, he agrees that the sole remedy available shall be enforcement of the terms of this Agreement and/or a claim for damages resulting from the breach of this Agreement, but that under no
circumstances shall the Executive be entitled to receive or collect any damages for claims that Executive has released under this Agreement.
