3.                                       Advisory Fee.

(a)                                  In consideration of BSMB’s undertaking to provide advisory services hereunder, the Company shall pay BSMB an annual advisory fee (the “Advisory Fee”) in an amount for each fiscal year equal to the greater of (x) $500,000 and (y) 0.75% of Adjusted EBITDA of the Company and its subsidiaries for the immediately preceding fiscal year,

2

calculated as provided below and payable in advance in quarterly installments, for the period beginning on the date hereof and ending upon the termination of this Agreement as provided in Section 1 hereof; provided, that the annual Advisory Fee for the fiscal year ending December 31, 2007 shall be $500,000. The Advisory Fees shall be payable by the Company whether or not the Company actually requests that BSMB provide the services described in Section 2 above. All Advisory Fees shall be fully earned when paid.

(b)                                 Except as otherwise provided in Section 3(c) or 3(d) hereof, all subsequent payments of the Advisory Fee shall be in quarterly installments, payable on March 31, June 30, September 30 and December 31 of each year, in an amount equal to the greater of (x) $125,000 or (y) the product of (i) 25% and (ii) 0.75% of Adjusted EBITDA of the Company and its subsidiaries for the immediately preceding fiscal year. Each scheduled installment of the Advisory Fee payable pursuant to this Section 3(b) will be reduced by the amount of the corresponding scheduled installment of the MBSS Fee (defined below), if any. Advisory Fees and MBSS Fees will be invoiced or accounted for separately.

(c)                                  Upon a Company Sale or the consummation of a Qualified Public Offering, the Company shall be obligated to pay to BSMB the Advisory Fee that would be payable to BSMB pursuant to this Section 3 in respect of the next four successive three-month periods calculated based on the Advisory Fee paid or payable for the then current three-month period (determined pursuant to Section 3(b) without reduction for any MBSS Fees).

(d)                                 Notwithstanding anything to the contrary contained herein, the Company shall accrue but not pay the Advisory Fee or MBSS Fee if and for so long as (i) any such payment would constitute a default (or any event which might, with the lapse of time or the giving of notice or both, constitute a default) under the Company’s financing agreements (a “Default”); provided, that the Company shall be obligated to pay any accrued Advisory Fees or MBSS Fees deferred under this clause (i) to the extent that such payment would not constitute a Default or (ii) BSMB instructs the Company not to pay all or any portion of the Advisory Fee or MBSS Fee during any fiscal year. Interest will accrue on all due and unpaid Advisory Fees or MBSS Fees not paid pursuant to clause (i) of the preceding sentence at the Default Rate until such Advisory Fees or MBSS Fees are paid, and such interest shall compound annually.

(e)                                  In addition to the Advisory Fee and MBSS Fee, the Company shall reimburse BSMB, promptly upon request, for all reasonable out-of-pocket expenses incurred in the ordinary course of business by BSMB in connection with BSMB’s obligations hereunder, including fees and expenses paid to consultants, subcontractors, advisors and other third parties in connection with such obligations.

(f)                                    In consideration for the Merchant Banking Strategic Services being provided by BSMB, the Company will pay BSMB an annual fee (the “MBSS Fee”), equal to an amount determined by BSMB at or prior to the commencement of the fiscal year to represent the fair market value of Merchant Banking Strategic Services to be provided by BSMB during the coming fiscal year. In no event shall the MBSS Fee exceed the amount that would have been payable by Company to BSMB as Advisory Fees under the Original Agreement for the same period. The MBSS Fee shall be payable in advance on each day on which as Advisory Fee is payable pursuant to Section 3(b) above for the period beginning on the date hereof and ending on the termination of this Agreement. All MBSS Fees shall be fully earned when paid, and shall not

3

be refundable, in whole or in part, regardless of whether or to what extent actual savings are realized under any Supply Agreement or all Supply Agreements in the aggregate. As and to the extent provided in Section 3(b), Advisory Fees payable under this Agreement will be reduced by MBSS Fees payable under this Agreement.

4.                                       Personnel. BSMB shall provide and devote to the performance of this Agreement such partners, employees and agents of BSMB as BSMB shall deem appropriate to the furnishing of the services required.

5.                                       Liability. None of BSMB, any of its affiliates nor their respective partners, members, employees or agents (collectively, the “BSMB Group”) shall be liable to the Company or its subsidiaries or affiliates for any loss, liability, damage or expense (collectively, a “Loss”) arising out of or in connection with the performance of services contemplated by this Agreement, unless and then only to the extent that such Loss is determined by a court in a final order from which no appeal can be taken, to have resulted solely from the gross negligence or willful misconduct on the part of such member of the BSMB Group. BSMB makes no representations or warranties, express or implied, in respect of the services to be provided by the BSMB Group. Except as BSMB may otherwise agree in writing on or after the date hereof:  (a) each member of the BSMB Group shall have the right to, and shall have no duty (contractual or otherwise) not to, directly or indirectly:  (i) engage in the same or similar business activities or lines of business as the Company or its subsidiaries and (ii) do business with any client, customer, supplier, lender or investor of, to or in the Company or its subsidiaries; (b) no member of the BSMB Group shall be liable to the Company or its subsidiaries or affiliates for breach of any duty (contractual or otherwise) by reason of any such activities or of such person’s participation therein; and (c) in the event that any member of the BSMB Group acquires knowledge of a potential transaction or matter that may be a corporate opportunity for both (A) the Company or any of its subsidiaries, on the one hand, and (B) BSMB, on the other hand, or any other person, no member of the BSMB Group shall have any duty (contractual or otherwise) to communicate or present such corporate opportunity to the Company or its subsidiaries and, notwithstanding any provision of this Agreement to the contrary, shall not be liable to the Company, its subsidiaries or any of their affiliates for breach of any duty (contractual or otherwise) by reasons of the fact that any member of the BSMB Group directly or indirectly pursues or acquires such opportunity for itself, directs such opportunity to another person, or does not present such opportunity to the Company, its subsidiaries or any of their affiliates. In no event will any of the parties hereto be liable to any other party hereto for any punitive, exemplary, indirect, special, incidental or consequential damages, including lost profits or savings, whether or not such damages are foreseeable, or in respect of any liabilities relating to any third party claims (whether based in contract, tort or otherwise), other than for the Claims (as defined in Section 6) relating to the services which may be provided by BSMB hereunder.

6.                                       Indemnity. The Company and its subsidiaries shall defend, indemnify and hold harmless each member of the BSMB Group from and against any and all Losses arising from any claim by any person with respect to, or in any way related to, this Agreement (including attorneys’ fees) (collectively, “Claims”) resulting from any act or omission of any member of the BSMB Group except to the extent that such Loss is determined by a court in a final order from which no appeal can be taken to have resulted solely from the gross negligence or willful misconduct of such member of the BSMB Group. The Company and its subsidiaries shall defend at its own cost and expense any and all suits or actions (just or unjust) which may be

4

brought against the Company and its subsidiaries or any member of the BSMB Group, or in which any member of the BSMB Group may be impleaded with others upon any Claims, or upon any matter, directly or indirectly, related to or arising out of this Agreement or the performance of the obligations hereunder by the BSMB Group, except that if such damage shall be proven to result solely from gross negligence or willful misconduct by a member of the BSMB Group, then such member of the BSMB Group shall reimburse the Company and its subsidiaries for the costs of defense and other costs incurred by the Company and its subsidiaries.
