               associated with moving your household belongings from Darien,

               you for normal closing costs associated with the sale of your
               home in Darien, Connecticut, grossed up to cover tax
               consequences. If you voluntarily leave the Company before

          execute and comply with the Proprietary Information and Inventions and

     6.  TERMINATION.

          (a)  At any time during the Executive Period, the Company may, at its
               sole discretion, discharge the Executive, with or without
               "cause".  Such termination shall be effective on delivery of
               written notice to the Employee of the Company's election to
               terminate this Agreement under this Section 6.  For purposes of
               this Agreement, the following events shall constitute "CAUSE":
               (i) the conviction of the Executive by a court of competent
               jurisdiction of a crime involving moral turpitude; (ii) the
               commission, or attempted commission, by the Executive of an act
               of fraud on the Company; (iii) the misappropriation, or attempted
               misappropriation, by the Executive of any funds or property of
               the Company; (iv) the continued and unreasonable failure by the
               Executive to perform in any material respect his obligations
               under the terms of this Agreement; (v) the knowing engagement by
               the Executive, without the written approval of the Board of
               Directors, in any direct, material conflict of interest with the
               Company without compliance with the Company's conflict of
               interest policy; (vi) the knowing engagement by the Executive,
               without the written approval of the Board of Directors, in any
               activity which competes with the business of the Company or which
               would result in a material injury to the Company; or (vii) the
               knowing engagement by the Executive in any activity that would
               constitute a material violation of the provisions of the
               Company's Insider Trading Policy or Business Ethics Policy, if
               any, then in effect.

               If the Company terminates the Executive's employment under this
               Agreement for reasons other than Cause, then the Company shall,
               subject to the terms of this Section 6, pay to the Employee (or
               his estate or representative, as appropriate) an amount equal to
               six (6) months compensation at his then current salary, payable
               bi-monthly or in accordance with the Company's payroll
               procedures, and shall continue to provide benefits in the kind
               and amounts provided up to the date of termination for the 6-
               month period, including, without limitation, continuation of any
               Company-paid benefits as described in Section 5 of this Agreement
               for the Executive and his family.  Under no circumstances shall
               the Executive be entitled to any compensation or continuation of
               benefits for any period of time following his termination if his
               termination is for Cause.  If the Company terminates the
               Executive's employment under this Agreement for reasons other
               than Cause, the Executive agrees to accept, in full settlement of
               any and all claims, losses, damages and other demands that the
               Executive may have arising out of such termination as liquidated
               damages and not as a penalty, the six-month salary payments and
               continuation of Company-paid benefits as set forth above.  The
               Executive hereby waives any and all rights that he may have to
               bring any cause of action or proceeding, as a result of such
               termination, except to enforce the Company's obligation to pay
               amounts owing pursuant to this Section 6.

          (b)  This Agreement will terminate automatically on the earliest to
               occur of:  (i) the death or disability of the Executive; (ii) the
               voluntary retirement of the Executive; or (iii) the expiration of
               the Executive Period unless otherwise renewed.

          (c)  If at any time during the term of this Agreement, the Executive
               is unable to perform effectively his duties hereunder because of
               physical or mental disability, the Company shall continue payment
               of compensation as provided in Section 3 hereof during the first
               six-month period of such disability to the extent not covered by
               the Company's disability insurance policies.  On the expiration
               of such six-month period, the Company, at its sole discretion,
               may continue payment of the Executive's salary for such
               additional periods as the Company elects or may terminate this
               Agreement without any further obligations thereunder.  If the
               Executive should die during the term of this Agreement, the
               Executive's employment and the Company's obligations hereunder
               shall terminate as of the last day of the month in which the
               Executive's death occurs.

          (d)  Notwithstanding the terms of Section 6(a) above, the Executive
               shall be obligated to actively pursue employment following
               termination of his employment to be entitled to be paid the
               continuation of salary provided in Section 6(a), and the
               Company's obligation to pay any such continuation of salary shall
               terminate at such time as the Executive commences employment with
               another employer; provided, however, that nothing herein shall
               obligate the Executive to pursue or accept employment for a
               position that is not commensurate with his current position at
               the Company or otherwise acceptable to him.

          (e)  At any time during the term of this Agreement, the Executive may
               terminate this Agreement by giving at least thirty days written
               notice to the Company of his intent to terminate this Agreement,
               with the date of termination to be specified in such notice.

          (f)  If this Agreement is terminated by the Executive pursuant to
               Section 6(e) hereof, then the Company will have no obligation to
               pay any amount to the Executive other than amounts earned or
               accrued pursuant to Section 3 hereof, but which have not yet been
               paid, as of the date of termination.

  7.  ASSIGNMENT BY EXECUTIVE. Except as otherwise expressly provided herein,
      the Executive agrees for himself, and on behalf of his executors and
      administrators, heirs, legatees, distributees and any other person or
      persons claiming any benefits under him by virtue of this Agreement, that
      this Agreement and the rights, interests and benefits hereunder shall not
      be assigned, transferred, pledged or hypothecated in any way by the
      Executive or any executor, administrator, heir, legatee, distributee or
      person claiming under the Executive by virtue of this Agreement and shall
      not be subject to execution, attachment or similar process. Any attempt at
      assignment, transfer, pledge or hypothecation or other disposition of this
      Agreement or of such rights, interests and benefits contrary to the
      foregoing provision, or the levy of any attachment or similar process
      thereupon, shall be null and void and without effect.

  8.  SUCCESSORS OF THE COMPANY. This Agreement shall be binding on and inure to
      the benefit of any Successor (as hereinafter defined) of the Company and
      any such Successor shall be deemed substituted for the Company under the
      terms of this Agreement. As used in this Agreement, the term "SUCCESSOR"
      shall include any person, firm, corporation or other business entity which
      at any time, whether by merger, purchase or otherwise, acquires all or
      substantially all of the assets or businesses of the Company; but no such
      substitution shall relieve such companies of their original obligations
      hereunder. This Agreement may not otherwise be assigned by the Company
      without the Executive's consent to any person, firm, corporation, limited
      liability company, trust or other entity.
