Employer, be made by

  In the event of a Change in Control (as hereinafter defined) of Employer,
Employer shall have the right to terminate this Agreement by giving written
notice to Employee specifying the intention to terminate this Agreement and the
effective date for such termination.  Any termination pursuant to this Section

the period of thirty (30) days immediately following the end of the one (1) year
period immediately subsequent to a Change of Control. Notwithstanding anything
herein to the contrary, Employee shall have the right to terminate this

pursuant to Sections 3.01(b) and 3.03 are diminished; or (3) the place of
Employee's employment is relocated more than twenty (20) miles from its location

Employee the obligations of Employer under this Agreement (each of the events
described in subparagraphs 1, 2, 3 and 4 of this Section 2.04 shall hereinafter
be referred to as Good Reason). For purposes of this Article 2, "Change of
Control" shall mean either (i) a merger or consolidation of Employer into
another corporation or a merger of another corporation with or into the
Employer; or (ii) a sale by Employer of substantially all of its assets, which,
in the case of either (i) or (ii) above, results in the shareholders of Employer

consolidation or sale) owning less than seventy percent (70%) of the surviving
entity or new corporation or entity that has acquired substantially all of the
Employer's assets after the effectiveness thereof; or (iii) a reorganization of

percent (70%) of the surviving corporation); (iv) the acquisition by any person,
entity or group of persons or entities acting in concert, of thirty percent
(30%) or more of Employer's then issued and outstanding voting securities,

5.08  Payment of Taxes.
      -----------------

     (a) Special Reimbursement.  In the event that Employee becomes entitled to
the Severance Compensation Payments; if any payment or benefit paid or payable,
or received or to be received, by or on behalf of the Employee in connection
with a Change in Control or the termination of Employee's employment, whether
any such payments or benefits are pursuant to the terms of this Agreement or any
other plan, arrangement or agreement with the Company, any of its subsidiaries,
any Person, or otherwise (the "Total Payments"), will or would be subject to the
excise tax imposed under section 4999 of the Code (the "Excise Tax"), the
Company shall pay to the Employee an additional amount (the "Gross-Up Payment")
which amount shall be equal to the sum of (a) the amount of such Excise Tax
imposed (determined without regard to the Gross-Up Payment), and (b) the product
of (i) such Excise Tax (determined without regard to the Gross-Up Payment), and
(ii) the rate of Excise Tax imposed on "golden parachute" payments under Section
4999 of the Code.
<PAGE>
 
                                     - 13 -

     (b) For purposes of determining whether any of the Total Payments will be
subject to the Excise Tax and the amount of such Excise Tax, (i) the Total
Payments shall be treated as "parachute payments" within the meaning of section
280G(b)(2) of the Code, and all "excess parachute payments" within the meaning
of section 280G(b)(1) of the Code shall be treated as subject to the Excise Tax,
unless in the opinion of tax counsel (delivered to Employee) selected by the
Company and reasonably acceptable to Employee, such Total Payments (in whole or
in part) (a) do not constitute parachute payments, including (without
limitation) by reason of section 280G(b)(4)(A) of the Code, (b) such excess
parachute payments (in whole or in part) represent reasonable compensation for
services actually rendered, within the meaning of section 280G(b)(4)(B) of the
Code, or (c) are otherwise not subject to the Excise Tax, and (ii) the value of
any non-cash benefits or any deferred payment or benefit shall be determined by
the Company's independent auditors in accordance with the principles of sections
280G(d)(3) and (4) of the Code.

     (c)  In the event that the Excise Tax is subsequently determined to be less
than the amount taken into account hereunder at the time of termination of
Employee's employment, Employee shall repay to the Company, at the time that the
amount of such reduction in Excise Tax is finally determined, the portion of the
Gross-Up Payment attributable to such reduction plus interest on the amount of
such repayment at the rate provided in section 1274(b)(2)(B) of the Code. In the
event that the Excise Tax is determined to exceed the amount taken into account
hereunder at the time of the termination of the Employee's employment (including
by reason of any payment, the
<PAGE>
 
                                     - 14 -

existence or amount of which cannot be determined at the time of the Gross-Up
Payment), the Company shall make an additional Gross-Up Payment in respect of
such excess (plus any interest, penalties or additions payable by Employee with
respect to such excess) at the time that the amount of such excess is finally
determined. The Employee and the Company shall each reasonably cooperate with
the other in connection with any administrative or judicial proceedings
concerning the existence or amount of any such subsequent liability for Excise
Tax with respect to the Severance Compensation.

5.09  Waiver of Breach.
      -----------------
