                  4.1. In addition to his salary, Executive will be eligible for

for Executive for such year as determined by the board of directors of the

                   Target                             50%
                   Maximum                           100%

option and similar plans and benefits of the Company from time to time in effect
for senior executives of the Company, subject to and in accordance with the
terms and conditions of each such plan or benefit; provided, however, that the
Company shall be entitled to modify or abolish any such plans or benefits and
nothing contained in this Agreement shall be deemed to limit the Company's
discretion to modify or abolish such plans or benefits for all covered
employees, including Executive. Executive acknowledges that any stock options or
other benefits that may be granted under the Company's stock option plan shall
be subject to the discretion of the board of directors of the Company. Executive

payments required to be made to Executive pursuant to this Agreement shall be

         9. EXCISE TAXES. In the event it shall be determined that any payment
by the Company to or for the benefit of Executive pursuant to Section 8 of this
Agreement (determined without regard to any additional payments required under
this Section 9) (a "PAYMENT") would be subject to the excise tax imposed by
Section 4999 of the Internal Revenue Code or any successor statute (the "EXCISE
TAX"), then Executive shall be entitled to receive an additional payment (an
"EXCISE TAX PAYMENT") in an amount equal to the Excise Tax.

                  9.1. All determinations required to be made under this Section
9, including whether and when an Excise Tax Payment is required, the amount of
such Excise Tax Payment and the assumptions to be utilized in arriving at such
determination, shall be made by a nationally recognized accounting firm as shall
be designated by the Company (the "ACCOUNTING FIRM"). All fees and expenses of
the Accounting Firm shall be paid by the Company. Any Excise Tax Payment, as
determined pursuant to this Section 9, shall be paid by the Company to Executive
(or to the Internal Revenue Service on Executive's behalf) within thirty (30)
days of the receipt of the Accounting Firm's determination. All determinations
made by the Accounting Firm shall be binding upon the Company and Executive.

                  9.2. Executive shall notify the Company in writing of any
claim by the Internal Revenue Service that, if successful, would require the
payment by the Company of the Excise Tax Payment. Such notification shall be
given as soon as practicable but no later than ten business days after Executive
receives written notification of such claim (provided, however, that the failure
to provide such notification within such period as provided herein shall not
relieve the Company of its obligations



                                      -5-
<PAGE>

under this Section 9 except to the extent that the Company is materially
prejudiced thereby) and shall apprise the Company of the nature of such claim
and the date on which such claim is requested to be paid. Executive shall not
pay such claim prior to the expiration of the 30-day period following the date
on which it gives such notice to the Company (or such shorter period ending on
the date that any payment of taxes with respect to such claim is due). If the
Company notifies Executive in writing prior to the expiration of such period
that it desires to contest such claim, Executive shall take such action in
connection with contesting such claim as the Company shall reasonably request
from time to time, including, without limitation, accepting legal representation
with respect to such claim by an attorney reasonably selected by the Company,
cooperating with the Company in good faith in order to effectively contest such
claim, and permitting the Company to participate in any proceeding relating to
such claim; provided, however, that the Company shall bear and pay directly all
reasonable costs and expenses (including additional interest and penalties)
incurred in connection with such contest. Without limiting the foregoing
provisions of this Section 9.2, the Company shall control all proceedings taken
in connection with such contest and may, at its sole option, either direct
Executive to pay the tax claimed and sue for a refund or contest the claim in
any permissible manner, as the Company shall determine and direct; provided,
however, that if the Company directs Executive to pay such claim and sue for a
refund, the Company shall advance the amount of such payment to Executive, on an
interest-free basis; and further provided that any extension of the statute of
limitations relating to the payment of taxes for Executive's taxable year with
respect to which such contested amount is claimed to be due is limited solely to
such contested amount. If any Excise Tax, employment tax or income tax is
imposed on Executive as a result of any costs and expenses paid by the Company
in connection with any contest relating to the Excise Tax in accordance with
this Section 9.2, then the Company shall reimburse Executive for the amount of
any such Excise Tax, employment tax or income tax so imposed on Executive as, if
and when any such tax is imposed on Executive. Furthermore, the Company's
control of the contest shall be limited to issues with respect to which an
Excise Tax Payment would be payable hereunder and Executive shall be entitled to
settle or contest, as the case may be, any other issue raised by the Internal
Revenue Service or any other taxing authority.

                  9.3. If, after Executive's receipt of an amount advanced by
the Company pursuant to this Section 9, Executive becomes entitled to receive
any refund with respect to such claim, Executive shall promptly pay to the
Company the amount of such refund attributable to the Excise Tax on the Payment.

                  9.4. The provisions of this Section 9 shall survive the
expiration of the Term.
