          assignment to him of any duties or work responsibilities which are
          inconsistent with such status, title, position or work
          responsibilities; or any removal of the Executive from, or failure to
          reappoint or reelect him to any of such positions, except if any such

              -------------------

          utilized in the calculation pursuant to this clause (2), provided,
                                                                   --------
          further, that for purposes of this Agreement, if the Date of
          -------
          Termination occurs before the end of the first fiscal year that ends
          after the Effective Date, the amount of the bonus paid by the Company
          to the Executive shall be deemed to be the Target Bonus and (B) the
          number two and one-half (2.5);

               (iii)  if it is determined that the Company has met financial
          objectives established pursuant to its Incentive Compensation Plan and
          to pay bonuses to eligible employees for the fiscal year within which
          the Date of Termination occurs, the Company shall pay the Executive,
          as long as the Executive is otherwise eligible for such payment, her
          bonus prorated for the period beginning on the first day of the fiscal
          year in which occurs the Date of Termination through Date of
          Termination, payable at the same time and in the same manner as the
          Company customarily pays such other bonuses;

               (iv) the Company shall continue coverage for the Executive, on
          the same terms and conditions as would be applicable if the Executive
          were an active Employee, under the Company's life insurance, medical,
          health and similar welfare benefit plans (other then group disability
          benefits) for a period of thirty-six (36) months.  Benefits otherwise
          receivable by the Executive pursuant to this Section 12(d)(iv) shall
          be reduced to the extent comparable benefits are actually received by
          the Executive from a subsequent employer during the period during
          which the Company is required to provide such benefits, and the
          Executive shall report any such benefits actually received by him to
          the Company; and

               (v) the payments provided for in this Section 12(d) (other than
          Section 12(d)(iv)) shall be made not later than the thirtieth (30th)
          day following the Date of Termination, provided, however, that if the
          amounts of such payments, and the limitation on such payments set
          forth in Section 16 hereof, cannot be finally determined on or before
          such day, the Company shall pay to the Executive on such day an
          estimate, as determined in good faith by the Company, of the minimum
          amount of such payments to which the Executive is clearly entitled and
          shall pay the remainder of such payments (together with interest at
          the rate provided in section 1274(b)(2)(B) of the Code (as defined in
          Section 16)) as soon as the amount thereof can be determined but in no
          event later than the sixtieth (60th) day after the Date of
          Termination. In the event that the amount of the estimated payments
          exceeds the amount determined by the Company within six (6) months
          after payment to have been due, such excess shall constitute a loan by
          the Company to the Executive, payable no later than the thirtieth
          (30th) business day after demand by the Company (together

                                       9
<PAGE>
 
          with interest at the rate provided in section 1274(b)(2)(B) of the
          Code). At the time that payments are made under this Section 12(d),
          the Company shall provide the Executive with a written statement
          setting forth the manner in which such payments were calculated and
          the basis for such calculations including, without limitation, any
          opinions or other advice the Company has received from outside
          counsel, auditors or consultants (and any such opinions or advice
          which are in writing shall be attached to the statement).

               (vi) If the Executive continues to be employed by the Company for
          one (1) year after a Change of Control and has not by such time given
          Notice of Termination for Good Reason, the Executive will have waived
          his right to exercise his rights under Section 12(d) hereof with
          respect to any act or failure to act which constitutes Good Reason.

          (e) If the Executive terminates his employment under clause (C) of
     Section 11(d) hereof or, prior to any Change of Control, the Company
     terminates the Executive's employment without Cause, then

               (i) the Company shall pay the Executive his base salary through
          the Date of Termination at the rate in effect at the time Notice of
          Termination is given and all other unpaid amounts, if any, to which
          the Executive is entitled as of the Date of Termination under any
          compensation plan or program of the Company, at the time such payments
          are due;

               (ii) the Company shall pay to the Executive the greater of either
          (A) the remaining amount of base salary owed for the Term; or (B) an
          aggregate amount equal to the sum of (1) twelve (12) months of the
          Executive's base salary at the rate in effect as of the Date of
          Termination plus (2) one (1) additional month of the Executive's base
          salary at such rate for each full year of service beyond the first
          anniversary of this Agreement, not to exceed twenty-four (24) months
          of base salary payments; such amount to be paid in substantially equal
          monthly installments during the period commencing with the month
          immediately following the month in which the Date of Termination
          occurs or in a lump sum payment, as decided by the Company;

               (iii)  if it is determined that the Company has met financial
          objectives established pursuant to its Incentive Compensation Plan and
          to pay bonuses to eligible employees for the fiscal year within which
          the Date of Termination occurs, the Company shall pay the Executive,
          as long as the Executive is otherwise eligible for such payment, her
          bonus 

                                       10
<PAGE>
 
          prorated for the period beginning on the first day of the fiscal
          year in which occurs the Date of Termination through Date of
          Termination, payable at the same time and in the same manner as the
          Company customarily pays such other bonuses;

               (iv) the Company shall continue coverage for the Executive, on
          the same terms and conditions as would be applicable if the Executive
          were an active employee, under the Company's life insurance, medical,
          health, and similar welfare benefit plans (other then group
          disability) for a period not to exceed the number of months the
          Executive will be paid under Section 12(e)(ii) beginning on the Date
          of Termination;

               (v) benefits otherwise receivable by the Executive pursuant to
          clause (iv) of this Section 12(e) shall be reduced to the extent
          comparable benefits are actually received by the Executive from a
          subsequent employer during the period which the Company is required to
          provide such benefits, and the Executive shall report any such
          benefits actually received by him to the Company;

               (vi) the payments made to the Executive under Section 12(e)
          hereof will be reduced by the amount of payments provided for by any
          subsequent employer of the executive for a position obtained after the
          Date of Termination.

          (f) If the Executive experiences a termination under Section 12(d) or
     12(e) hereof, until the Executive finds another full-time position or for 6
     months, whichever is earlier, the Company shall provide the Executive with
     professional outplacement services of the Executive's choosing and shall
     reimburse the Executive documented incidental outplacement expenses
     directly related to the Executive's job search such as resume mailing,
     interview trips, and clerical support, subject to a maximum cost of $10,000
     for such outplacement services and incidental expenses.  The Executive's
     choice of professional outplacement services is subject to the Company's
     reasonable prior approval.  If the Company has not approved or disapproved
     of the Executive's choice within ten (10) business days of receiving notice
     of such choice, the Company will be deemed to have given is approval.  Any
     approval by the Company will be in writing and will state the basis for
     such disapproval.  The Executive will not be entitled to receive cash or
     lieu of the professional outplacement services provided pursuant to this
     Section.

          (g) If the Executive shall terminate his employment under clause (B)
     of Sections 11(d) or 11(e) hereof, the Company shall pay the Executive his
     base salary through the Date of Termination at the rate in effect at the
     time Notice of 

                                       11
<PAGE>
 
     Termination is given, and the Company shall have no further obligations to
     the Executive under this Agreement.

          (h) The Executive shall not be required to mitigate the amount of any
     payment provided for in this Section 12 by seeking other employment or
     otherwise, and, except as provided in Sections 12(e) hereof, the amount of
     any payment or benefit provided for in this Section 12 shall not be reduced
     by any compensation earned by the Executive as the result of employment by
     another employer or by retirement benefits.

          (i) Release. Prior to making any payment pursuant to Sections
              -------                                                  
     12(d)(iii) and 12(d)(iv) or Sections 12(e)(ii) and 12(e)(iii), whichever is
     applicable, the Company shall have the right to require the Executive to
     sign, and the Executive hereby agrees to sign, an agreement to be bound by
     the terms of Section 15 of this Agreement and a waiver of all claims the
     Executive may have (including any claims under the Age Discrimination in
     Employment Act), and the Company may withhold payment of such amount until
     the period during which the Executive may revoke such waiver (normally
     seven days) has elapsed.

     materials, ideas, discoveries, techniques or programs developed or

     be subject to the covenants contained in the preceding paragraph.

          (c) The Executive covenants and agrees that during the Term and, if
     the Executive's employment is terminated by the Executive for other than
     Good Reason, for a period of two (2) years following the termination of the

     director, principal, officer, or agent of, enter into the employment of, or
     act as a consultant to, in any case in which he has control or supervision
     over a significant portion of any entity of which either (A) (i) the

     legal and equitable remedies available for violation by the Executive of
     the covenants contained in this Section 15, it is expressly agreed by the
     Executive and the Company that such other remedies cannot fully compensate
     the Company for any such violation and that the Company shall be entitled
     to injunctive relief, without the necessity of proving actual monetary
     loss, to prevent any such violation or any continuing violation thereof.
     Each party intends and agrees that if in any action before any court or
     agency legally empowered to enforce the covenants contained in this Section
     15, any term, restriction, covenant or promise contained herein is found to
     be unreasonable and accordingly unenforceable, then such term, restriction,
     covenant or promise shall be deemed modified to the extent necessary to
     make it enforceable by such court or agency. The covenants 

                                       14

     contained in Section 15 shall survive the conclusion of the Executive's

     16.  Prohibition on Parachute Payments.
          --------------------------------- 

          (a) Notwithstanding any other provisions of this Agreement, any
     payment or benefit received or to be received by the Executive in
     connection with a Change in Control of the Company or the termination of
     the Executive's employment (whether pursuant to the terms of this Agreement
     or any other plan, arrangement or agreement with the Company, any person
     whose actions result in a Change in Control or any Person affiliated with
     the Company or such Person) (all such payments and benefits, including,
     without limitation, base salary and bonus payments, being hereinafter
     called "Total Payments") would not be deductible (in whole or in part), by
     the Company, an affiliate or any Person making such payment or providing
     such benefit as a result of section 280G of the Internal Revenue Code of
     1986, as amended (the "Code"), then, to the extent necessary to make such
     portion of the Total Payments deductible (and after taking into account any
     reduction in the Total Payments provided by reason of section 280G of the
     Code in such other plan, arrangement or agreement), (A) such cash payments
     shall first be reduced (if necessary, to zero), and (B) all other non-cash
     payments by the Company to the Executive shall next be reduced (if
     necessary, to zero). For purposes of this limitation (i) no portion o the
     Total Payments the receipt or enjoyment of which the Executive shall have
     effectively waived in writing prior to the Date of Termination shall be
     taken into account, (ii) no portion of the Total Payments shall be taken
     into account which in the opinion of tax counsel selected by the Company's
     independent auditors and reasonably acceptable to the Executive does not
     constitute a "parachute payment" within the meaning of section 280G(b)(2)
     of the Code, including by reason of section 280G(b)(4)(A) of the Code,
     (iii) such payments shall be reduced only to the extent necessary so that
     the Total Payments (other than those referred to in clauses (i) or (ii)) in
     their entirety constitute reasonable compensation for services actually
     rendered within the meaning of section 280G(b)(4)(B) o the Code or are
     otherwise not subject to disallowance as deductions, in the opinion of the
     tax counsel referred to in clause (ii); and (iv) the value of any non-cash
     benefit or any deferred payment or benefit included in the Total Payments
     shall be determined by the Company's independent auditors in accordance
     with the principles of sections 280G(d)(3) and (4) of the Code.

          (b) If it is established pursuant to a final determination of a court
     or an Internal Revenue Service proceeding that, notwithstanding the good
     faith of the Executive and the Company in applying the terms of this
     Section 16, the aggregate "parachute payments" paid to or for the
     Executive's benefit are in an amount that would result in any portion of
     such "parachute payments" not 

                                       15
<PAGE>
 
     being deductible by reason of section 280G of the Code, then the Executive
     shall have an obligation to pay the Company upon demand an amount equal to
     the sum of (i) the excess of the aggregate "parachute payments" paid to or
     for the Executive's benefit over the aggregate "parachute payments" that
     could have been paid to or for the Executive's benefit without any portion
     of such "parachute payments" not being deductible by reason of section 280G
     of the Code; and (ii) interest on the amount set forth in clause (i) of
     this sentence at the rate provided in section 1274(b)(2)(B) of the Code
     from the date of the Executive's receipt of such excess until the date of
     such payment.

     17.  Entire Agreement.  This Agreement contains all the understandings
          ----------------
