2. Term. The term of this Letter Agreement (the "Term") shall commence on the
Effective Date and shall continue until the Final Payment Date.

employment with the Company during the period beginning on the Effective Date
and continuing through each Payment Date, the Company will pay you a Retention
Bonus equal to 20%, 25%, 25% and 30%, respectively, of the annual rate of your
base salary as in effect on the Effective Date. The Company will pay each
Retention Bonus to you in a lump sum cash amount as soon as practicable after
each Payment Date where you remain in the continued employ of the Company, but
in no event shall such payment be made more than thirty days thereafter.
Notwithstanding the above, if you are in the employ of the Company and there is
a Change in Control following a Triggering Event during the term of this Letter
Agreement, any remaining Retention Bonuses will be paid to you as soon as
practicable, but in no event later than thirty days, following such Change in
Control.

4. Effect of Termination of Employment.

(a) Involuntary Termination. In the event of your Involuntary Termination prior
to any of the Payment Dates, you shall be entitled to receive the Retention
Bonus in accordance with the terms of Section 3, as if your employment had
continued until such Payment Dates as occurs after the date of the termination
of your employment. Such payment shall be in addition to any benefits you may be
eligible for under the Company's severance plan.

reason other than an Involuntary Termination prior to any of the Payment Dates,
you shall forfeit your right any portion of the Retention Bonus not yet earned.

herewith, except that notice of change of address shall be effective only upon

6. Reduction of Payments if Reduction Would Result in Greater After-Tax Amount.
Notwithstanding anything herein to the contrary, if the payment of the Retention
Bonus and any other payments in connection with a Change of Control (together,
the "Payments") constitute a "parachute payment" (as defined in Section
280G(b)(2) of the Internal Revenue Code of 1986, as amended (the "Code")), and
the amount of the Payments net the excise tax (as described in Section 4999 of
the Code) payable with respect thereto is less than the amount to be paid to you
if the aggregate Payments to be made to you were three times your "base amount"
(as defined in Section 280G(b)(3) of the Code), less $1.00, then the aggregate
of the Payments constituting the parachute payment paid pursuant to this
Agreement shall be reduced to an amount that will equal three times your base
amount, less $1.00.

7. Miscellaneous.

(a) No Rights to Continued Employment. Neither this Letter Agreement nor any of
the rights or benefits evidenced hereby shall confer upon you any right to
continuance of employment by the Company or interfere in any way with the right
of the Company to terminate your employment, subject to the provisions of
Section 4 above, for any reason, with or without Cause.

(b) Amendments, Waivers. No provision of this Letter Agreement may be modified,
waived or discharged unless such waiver, modification or discharge is agreed to
in writing by the parties hereto. No waiver by either party hereto at any time
of any breach by the other party hereto of, or compliance with, any condition or
provision of this Letter Agreement to be performed by such other party shall be
deemed a waiver of similar or dissimilar provisions or conditions at the same or
at any prior or subsequent time.

(c) Counterparts. This Letter Agreement may be executed in counterparts, each of
which shall be deemed to be an original but all of which together will
constitute one and the same instrument.

(d) Withholding. Amounts paid to you hereunder shall be subject to all
applicable federal, state and local wage withholdings.

(e) Headings. The headings contained in this Letter Agreement are intended
solely for convenience of reference and shall not affect the rights of the

will then constitute our agreement on this subject.

                          Sincerely,
