<PAGE>
         No Sponsor shall have any obligation to the Company as to the method
and time of rendering its services hereunder, and the Company shall not have any
right to dictate or direct the details of the performance of services rendered
hereunder. This Agreement shall in no way prohibit a Sponsor or any of its
Affiliates or employees from engaging in other activities, whether or not
competitive with any business of the Company of any of its Affiliates.

2. PAYMENT OF FEES. In exchange for each Sponsor's agreement to provide the

accordance with Section 3 below. Each payment made pursuant to this Section 2
shall be paid by wire transfer of immediately available funds to the accounts
specified on Exhibit A, attached hereto, or to such other account(s) as each
Sponsor may specify in writing to the Company.

until (i) terminated by a Sponsor (with respect to itself and not any other
Sponsor) upon 30 days notice to the Company and the other Sponsor, (ii)
terminated upon the mutual consent of the Sponsors upon 30 days notice to the
Company, (iii) terminated automatically, with respect to a particular Sponsor,
on the date which such Sponsor no longer owns at least 5% of the equity

Sponsor (with respect to itself and not any other Sponsor) upon the consummation
of Holding's Initial Public Offering (as defined in the Stockholders' Agreement
between Holdings, the Sponsors, and the other parties thereto), or a change in
law, event, or other occurrence (together with the Initial Public Offering, an
"Adverse Event") which, in the determination of such Sponsor and a majority of
Holding's Board of Directors, causes the existence of this Agreement to (A)
render any director designated by such Sponsor as an "interested" or otherwise
not an "independent" director, (B) adversely affect such Sponsor's right to
designate a Person or Persons to serve on the Company's board of directors, or
(C) affect the ability of a Person who has been designated by such Sponsor to
serve on the Company's board of directors to perform his duties as a director.
Upon any termination of this Agreement, each of (a) the obligations of the
Company under Section 4 below, (b) any and all owed and unpaid obligations of
the Company under Section 2 above and (c) the provisions of Section 7 shall

applicable law. In the event that a Sponsor terminates this Agreement in
accordance with Section 3, clause (iv) above, the Company agrees to pay such
Sponsor a cash lump-sum termination fee equal to the net present value of the
fees that would have been payable to such Sponsor (but for the termination
hereof) pursuant to Section 2 hereof for a period of ten (10) years from the
date of such termination calculated using a discount rate equal to the ten-year
treasury rate on the date of such termination. Such termination fee shall be
payable by wire transfer of immediately available funds within 10 days after the
date of termination to the account specified on Exhibit A, attached hereto, or
to such other account(s) as such Sponsor may specify in writing to the Company.
