WHEREAS, as of the Effective Date, Parent and Merger Sub have entered into an Advisory Agreement (the “GGC Agreement”) with GGC Administration, LLC, a Delaware limited liability company (“GGC”), with the “Management Fees” as defined therein referred to herein as “GGC Management Fees”).

WHEREAS, Parent and Merger Sub desire to retain Moulin with respect to the services described herein.

NOW, THEREFORE, the parties agree as follows:

1. Term. This Agreement shall be in effect for a term commencing on the Closing Date (as defined in the Merger Agreement) (the “Commencement Date”) and ending on the tenth anniversary of the Commencement Date (the “Term”), and shall be automatically extended thereafter on a year to year basis unless Parent or Moulin provides written notice of its desire to terminate this Agreement to the other parties 30 days prior to the expiration of the Term or any extension thereof.

2. Services. During the Term, Moulin shall perform or cause to be performed such services for the Company and/or its Subsidiaries as mutually agreed by Moulin and Parent’s board of directors, which may include, without limitation, the following:

(a) general executive and management services;

3. Management Fees; Expense Reimbursement.

(a) During the Term of this Agreement, Moulin or its designee(s) will be promptly (x) reimbursed for the Covered Expenses, as defined below, of Moulin and its Affiliates, plus (y) paid fees (the “Management Fees”) as set forth below. The Management Fees will be payable by the Company (as successor to Merger Sub) to Moulin or its designee(s) as follows:

(i) non-refundable Management Fees for the first eighteen months of the Term (in the amount of $1,500,000) shall be paid in advance on the Closing Date,

(ii) beginning on August 15, 2006, and on each three-month anniversary thereafter until and including such time (the “Continuation Time”) on such date (the “Continuation Date”) as the cumulative Management Fees paid to Moulin hereunder equal $3,000,000 (it being agreed and understood that the Continuation Time shall have occurred once Moulin has received that portion of the Management Fee (the “Continuation Time Payment”) being paid on such date which, when added to all prior Management Fees paid to Moulin pursuant to this Agreement, is equal to $3,000,000 and that any other portion of such payment shall be deemed to have been made following the Continuation Time) an amount of $500,000 on such quarterly payment date; provided, however, that the Company shall not pay the portion of any such Management Fees payable on that date to the extent that the sum of such Management Fees payable on that date plus the aggregate amount of Management Fees paid during the 364 days immediately preceding such date exceeds the lesser of (A) two percent (2%) of the the “Consolidated EBITDA” (as defined in that certain trust indenture for the benefit of the Company’s bondholders established concurrently with the Merger) for the last four fiscal-quarters of the Company for which quarterly financial statements are available on the relevant payment date and (B) $2,000,000 (and any such excess amount that is not paid as a result of this proviso shall never be paid and shall not be accrued or deferred for any purpose);

(iii) immediately following the Continuation Time but on the Continuation Date, an amount equal to 50% of the difference between $500,000 and the Continuation Time Payment; provided, however, that the Company shall not pay the portion of any such Management Fees to the extent that the sum of (x) the product of two multiplied by the amount

- 2 -

of such Management Fees plus (y) the Continuation Time Payment plus (z) the aggregate amount of Management Fees and GGC Management Fees paid during the 364 days immediately preceding such date exceeds the lesser of (A) two percent (2%) of the Consolidated EBITDA for the last four fiscal-quarters of the Company for which quarterly financial statements are available on the relevant Payment Date and (B) $2,000,000 (and any such excess amount that is not paid as a result of this proviso shall never be paid and shall not be accrued or deferred for any purpose);

(iv) beginning on the three-month anniversary of the Continuation Date and on each three-month anniversary thereafter during the Term (each such date, a “Payment Date”), an amount equal to $250,000; provided, however, that the Company shall not pay the portion of any such Management Fees to the extent that the sum of (x) the product of two multiplied by the amount of such Management Fees payable on such date plus (y) the aggregate amount of Management Fees and GGC Management Fees paid during the 364 days immediately preceding such date exceed the lesser of (A) two percent (2%) of the Consolidated EBITDA for the last four fiscal-quarters of the Company for which quarterly financial statements are available on the relevant Payment Date and (B) $2,000,000 (and any such excess amount that is not paid as a result of this proviso shall never be paid and shall not be accrued or deferred for any purpose).

(b) The Covered Expenses will be payable by Parent and the Company (as successor to Merger Sub) to Moulin or its designee(s) on a quarterly basis in arrears commencing on the Effective Date, upon presentation by Moulin of reasonably detailed invoices for such expenses. The term “Covered Expenses” shall mean those third-party fees and expenses: (i) reasonably incurred in connection with the services contemplated by this Agreement, (ii) relating to the review, preparation, negotiation and execution of any amendments or waivers (whether or not the same become effective) or the enforcement of any rights by the Moulin Group (defined below) under or in respect of this Agreement or the other Transaction Documents; (iii) relating to any proposed merger, sale or recapitalization or debt or equity financing of the Company), or (iv) reasonably incurred in connection with any transaction, claim or event which Moulin believes affects the Company or the investment of Moulin and its Affiliates in the Company and as to which Moulin or its Affiliates seek advice of counsel (in each case, including without limitation fees and expenses of counsel and accountants); provided, however, that Parent and the Company shall have no obligation to reimburse Moulin and its Affiliates for any Covered Expenses in excess of $125,000 during any twelve month period.

(c) The payment of all Management Fees payable hereunder shall be deferred (but such amounts will nonetheless continue to be accrued, without interest) at any time that they are not permitted to be paid by Parent or the Company in accordance with the terms of the Credit Agreement, and any payment of any such deferred fees shall thereafter be paid, subject to the proviso to the second sentence of Section 3(a), at the earliest time (whether or not the Term has ended prior thereto) that payment thereof becomes permitted to be paid in accordance with the terms of the Credit Agreement.

4. Transaction Fees. During the Term, the Company will pay to Moulin or its designee(s) a transaction fee in connection with the consummation of each transaction resulting in a Change in Control (as defined below), acquisition, divestiture or financing (whether debt or equity financing) by or involving Parent or its subsidiaries in an amount equal to 0.5% of the aggregate value of each such transaction (in each case, whether such transaction is by way of merger, purchase or sale of stock, purchase or sale or other disposition of assets, recapitalization, reorganization, consolidation, tender offer, public or private offering or otherwise, and whether consummated directly by Parent or its Subsidiaries or indirectly by their respective stockholders). “Change in Control” means (i) any sale or transfer by Parent or its Subsidiaries of all or substantially all of their assets on a consolidated basis (as determined under Delaware law), (ii) any consolidation, merger or reorganization of Parent with or into any other entity or entities as a result of which the holders of Parent’s outstanding capital stock possessing the voting power (under ordinary circumstances) to elect a majority of the board of directors immediately prior to such consolidation, merger or reorganization cease to own the outstanding capital stock of the surviving corporation possessing the voting power (under ordinary circumstances) to elect a majority of the surviving corporation’s board of directors or (iii) issuance by Parent or sale or transfer to any third party of shares of Parent’s capital stock by the holders thereof as a result of which the holders of Parent’s outstanding capital stock possessing the voting power (under ordinary circumstances) to elect a majority of the board of directors immediately prior to such sale or transfer cease to own the outstanding capital stock of Parent possessing the voting power (under ordinary circumstances) to elect a majority of the board of directors.

5. Personnel. Moulin will provide and devote to the performance of this Agreement such partners, employees and agents of Moulin and its Affiliates as Moulin shall deem appropriate to the furnishing of the services mutually agreed upon by Parent and Moulin.
