       3. ENTITLEMENT UPON TERMINATION BY THE COMPANY WITHOUT CAUSE OR BY THE
EXECUTIVE FOR GOOD REASON FOLLOWING A CHANGE IN CONTROL.

           In the event of termination of the Executive's employment within two
years following a Change in Control (a) by the Company without Cause or (b) by
the Executive for Good Reason, he shall be entitled to the following:

           (A) GENERAL ENTITLEMENT:

               (i) his Base Salary through the date of termination;

               (ii) payment in lieu of any unused vacation, in accordance with
the Company's vacation policy and applicable laws;

               (iii) any annual or discretionary bonus earned but not yet paid
to him for any calendar year prior to the year in which his termination occurs;
and

               (iv) reimbursement of any business expenses incurred by the
Executive through the date of termination but not yet paid to him.

           (B) CHANGE-IN-CONTROL ENTITLEMENT:

               (i) 2 times the sum of (A) his Base Salary, at the rate in effect
immediately before such termination, and (B) the average of his annual bonuses
paid in the three calendar years prior to the year in which termination occurs,
such amount to be paid promptly to the Executive in a cash lump sum; and

                                                                               7
<PAGE>

               (ii) continuing coverage under the life, disability, accident and
health insurance programs covering senior executives of the Company generally,
as from time to time in effect, for the two-year period from such termination.

           (C) DETERMINATION OF AMOUNT OF PAYMENT. The Company, at its sole
expense, shall cause its independent certified public accountants (the
"Accountants") to promptly review all payments, distributions, and benefits that
have been made to or provided to, and are to be made to or provided to,
Executive under this Agreement and any other agreement and plan, to determine
the applicability of Code Section 4999. If the Accountants determine that any
such payments, distributions, or benefits are subject to excise tax under Code
Section 4999, such payments, distributions, or benefits (the "Original
Payment(s)") shall be increased by an amount (the "Gross-up Amount") such that,
after the Company withholds all federal, state, and local taxes due, including
without limitation all excise, employment, and income taxes imposed on the
Gross-up Amount, Executive shall retain a net amount equal to the Original
Payment(s) less employment and income taxes, if any, imposed on the Original
Payment(s). To facilitate the calculation of the applicable excise tax,
Executive shall provide the Accountants with copies of Executive's Forms W-2 for
the tax years the Accountants determine appropriate for their use in determining
the application of Code Section 4999 and calculating any amounts payable under
this Section 3(c). The Accountants shall perform the calculations in conformance
with the provisions of this Section 3(c), and shall provide Executive with a
copy of their calculations. The Company shall be solely responsible for, and
shall pay, all excise tax on the Original Payment(s) and Gross-up Amount, and
all federal, state and local employment and income taxes,

                                                                               8
<PAGE>

interest, additions to tax, and penalties imposed on the Gross-up Amount. If no
determination by the Accountants is made prior to the time Executive must file a
tax return reporting any portion of the Original Payment(s), Executive shall
receive a Gross-up Amount calculated on the basis of the Original Payment(s)
Executive reports on his tax return. In this case, the Company shall pay the
Gross-up Amount within thirty (30) days prior to the filing of the tax return.
If any tax authority finally determines that a greater excise tax is to be
imposed on the Original Payment(s) than is determined by the Accountants or
reported on Executive's tax returns, Executive shall receive the full Gross-up
Amount calculated on the additional amount of excise tax, interest, additions to
tax, and penalties determined to be payable by such tax authority. The Company
shall pay the additional Gross-up Amount within thirty (30) days of this
determination. If any tax authority finally determines that the excise tax is
less than the amount taken into account hereunder in calculating the Gross-up
Amount, Executive shall repay to the Company, within thirty (30) days of this
determination, the portion of the Gross-up Amount attributable to the reduction
in excise tax, plus that portion of the Gross-up Amount attributable to the
excise tax and federal, state, and local employment and income taxes imposed on
the Gross-up Amount being repaid. If any tax authority finally determines that
the excise tax is more than the amount taken into account hereunder and
calculating the Gross up amount, the Company (or its successors in interest)
shall pay Executive an additional Gross up Amount to take into account the
additional excise tax.

                                                                               9
<PAGE>

       4. NO MITIGATION

           The Company agrees that if the Executive's employment with the
Company terminates, he shall not be obligated to seek other employment or to
attempt to reduce any amount payable to him under this Agreement. Further, no
amount of any payment hereunder shall be reduced by any compensation earned by
the Executive as the result of employment by a subsequent employer or otherwise.

       5. NOTICES.

Agreement shall be in writing and shall be deemed to have been duly given when
