performed, BMP shall be entitled to receive upon consummation of: 
 (i) any such acquisition, divestiture, disposition,
merger, consolidation, restructuring or recapitalization, a non-refundable and irrevocable fee equal to (x) 1% of the aggregate enterprise value of the acquired, divested, merged, consolidated, restructured or recapitalized entity (calculated,

acquisition, divestiture, disposition, merger, consolidation, restructuring, refinancing, recapitalization, issuance of private or public debt or equity securities (including, without limitation, an initial public offering of equity securities),
financing or similar transaction, it will notify the Advisors of such determination in writing. Promptly thereafter, upon the request of BMP, the parties will negotiate in good faith to agree upon appropriate services, compensation and
indemnification for the Company or such subsidiary to hire BMP or one of its Affiliates for such services. The Company and its subsidiaries may not hire any person, other than BMP or one of its Affiliates, to perform any such services unless all of
the following conditions have been satisfied: (i) the parties are unable to agree upon the terms of the engagement of BMP or its Affiliate to render such services after 30 days following receipt by BMP of such written notice; (ii) such
other person has a reputation that is at least equal to the reputation of BMP or its Affiliate in respect of such services; (iii) ten business days have elapsed after the Company or such subsidiary provides a written notice to BMP of its
intention to hire such other person, which 

  

 3 








 
notice shall identify such other person and shall describe in reasonable detail the nature of the services to be provided, the compensation to be paid and
the indemnification to be provided; (iv) the compensation to be paid is not more than BMP or its Affiliate was willing to accept in the negotiations described above; and (v) the indemnification to be provided is not more favorable to the
Company or the applicable subsidiary than the indemnification that BMP or its affiliate was willing to accept in the negotiations described above. 
 SECTION 4. Advisory Fee. 
 (a) In consideration of the Services being rendered by the Advisors, the Company will
pay, or will cause to be paid, to the Advisors an annual non-refundable and irrevocable advisory fee (the “Advisory Fee”; the term “Advisory Fee” as used in this Agreement with respect to any annual period means all
amounts payable with respect to such annual period pursuant to Sections 4(b) or (c) hereof, as applicable; provided that notwithstanding anything to the contrary contained in this Agreement, the minimum annual Advisory Fee payable to the
Advisors shall be $10,000,000). 
 (b) The Advisory Fee for the year ending June 30, 2007 shall be equal to $2,219,200, which shall be
paid, or caused to be paid, by the Company at the Closing in respect of Services to be rendered from the Closing Date to June 30, 2007. 
 (c) The Advisory Fee for fiscal year 2008 and each subsequent year shall be equal to the greater of $10,000,000 or 3% of Consolidated EBITDA (as defined in the Credit Agreement dated as of April 10, 2007, by and among the Company;
Morgan Stanley Senior Funding, Inc. as administrative agent, collateral agent, swing line lender, joint lead arranger and joint bookrunner; Goldman Sachs Credit Partners L.P., as joint lead arranger, joint bookrunner and syndication agent; Bank of
America, NA., as joint bookrunner and co-documentation agent; Bear Stearns Corporate Lending Inc. as joint bookrunner and co-documentation agent; General Electric Capital Corporation, as co-documentation agent; and the lenders from time to time
party thereto). The Company will pay, or cause to be paid, to the Advisors, $10,000,000 on July 1, 2007, and thereafter on July 1 of each subsequent year. Following the preparation of the Company’s audited financial statements for
each fiscal year beginning with the fiscal year ending June 30, 2008, the Company shall calculate Consolidated EBITDA for such fiscal year. If 3% of Consolidated EBITDA for such year exceeds $10,000,000, the Company shall pay the Advisors the
amount of such excess. 
 (d) In the event the Company or any of its subsidiaries enters into a business combination transaction with another
entity that is large enough to constitute a “significant subsidiary” of the Company under any of the relevant tests contained in Regulation S-X as promulgated by the Securities and Exchange Commission, the Company and BMP will mutually
agree, following good faith negotiations, on an appropriate increase in the minimum annual Advisory Fee as warranted by the increase in the Company’s size. Such increase will be based on the percentage increase in the Company’s EBITDA
determined on a pro forma basis giving effect to such business combination transaction. 
 (e) To the extent the Company cannot pay, or cause
to be paid, the Advisory Fee for any reason, including by reason of any prohibition on such payment pursuant to any 

  

 4 








 
applicable law or the terms of any debt financing of the Company or its subsidiaries, the payment by the Company or any of its subsidiaries to the Advisors

its subsidiaries, as applicable, is otherwise able to make such payment, or cause such payment to be made, and (ii) total or partial liquidation, dissolution or winding up of the Company. Notwithstanding anything to the contrary herein, under
any applicable law or under any contract applicable to the Company or its subsidiaries, any forbearance of collection of the Advisory Fee by the Advisors shall not be deemed to be a subordination of such payments to any other person, entity or
creditor of the Company or its subsidiaries. Any such forbearance shall be at BMP’s sole option and discretion and shall in no way impair any Advisor’s right to collect such payments. Any installment of the Advisory Fee not paid on the
scheduled due date will bear interest, payable in cash on each scheduled due date, at an annual rate of 10%, compounded quarterly, from the date due until paid. 
 (f) Notwithstanding anything to the contrary contained in this Agreement, BMP may elect (on behalf of the Advisors) (in its sole discretion by the delivery of written notice to the Company) at any time in connection
with or in anticipation of a change of control of the Company, a sale of all or substantially all of the Company’s assets or an initial public offering of the equity of the Company or its successor (or at any time thereafter) to receive, in
consideration of the termination of the Services and for any remaining Advisory Fees payable by the Company under this Agreement and in addition to any fees owing to the BMP in connection with such transaction pursuant to Section 3(b) hereof, a
single lump sum non-refundable and irrevocable cash payment (the “Lump Sum Fee”) equal to the then present value (using a discount rate equal to the yield to maturity on the date of such written notice of the class of outstanding
U.S. government bonds having a final maturity closest to the tenth anniversary of the date of this agreement (the “Discount Rate”)) of all then current and future Advisory Fees payable under this Agreement, assuming the Termination
Date is the tenth anniversary of the date of such election. Promptly after the receipt of such written notice, the Company shall pay the Lump Sum Fee to the Advisors by wire transfer in same-day funds to the bank account or accounts designated by
the Advisors, which payment shall not be refundable under any circumstances. Following the payment of the Lump Sum Fee, the obligation of the Advisors to provide the Services hereunder, and the obligations of the Company to pay Advisory Fees, shall
be terminated, but all other provisions of this Agreement shall continue unaffected. 
 (g) To the extent the Company does not pay, or cause
to be paid, any portion of the Lump Sum Payment by reason of any prohibition on such payment pursuant to any applicable law, the terms of any agreement or indenture governing indebtedness of the Company or its subsidiaries, any unpaid portion of the
Lump Sum Payment shall be paid to the Advisors on the first date on which the payment of such unpaid amount is permitted under such agreement or indenture. Notwithstanding anything to the contrary herein, under any applicable law or under any
contract applicable to the Company or its subsidiaries, any forbearance of collection of the Lump Sum Fee by the Advisors shall not be deemed to be a subordination of such payments to any other person, entity or creditor of the Company or its
subsidiaries. Any such forbearance shall be at BMP’s sole option and discretion and shall in no way impair any Advisor’s right to collect such payments. Any portion of the Lump Sum Payment not paid on the scheduled due date shall bear
interest at an annual rate equal to the Discount Rate, compounded quarterly, from the date due until paid. 
  

 5 








 (h) Each of the Advisors shall receive its Pro Rata Share of the Advisory Fee and the Lump Sum Payment.

 SECTION 5. Reimbursements. In addition to the fees payable pursuant to this Agreement, the Company will pay, or cause to
be paid, directly, or reimburse the Advisors and each of their Affiliates for, their respective Out-of-Pocket Expenses (as defined below). For the purposes of this Agreement, the term “Out-of-Pocket Expenses” means the out-of-pocket
costs and expenses incurred by the advisors and their Affiliates in connection with the Transactions and the Services or other services provided by them under this Agreement (including prior to the Effective Time), or in order to make Securities and
Exchange Commission and other legally required filings relating to the ownership of equity securities of the Company or its successor by the Advisors or their Affiliates, or otherwise incurred by the Advisors or their Affiliates from time to time in
the future in connection with the ownership or subsequent sale or transfer by the Advisors or their Affiliates of capital stock of the Company or its successor, including, without limitation, (a) fees and disbursements of any independent
professionals and organizations, including independent accountants, outside legal counsel or consultants, retained by an Advisor or any of its Affiliates, (b) costs of any outside services or independent contractors such as financial printers,
couriers, business publications, on-line financial services or similar services, retained or used by an Advisor or any of its Affiliates, and (c) transportation, per diem costs, word processing expenses or any similar expense not associated

reimbursement in accordance with this Agreement, to the bank account indicated to the Company by the relevant payee. 
 SECTION 6. Indemnification. 
 The Company will indemnify and hold harmless the Advisors, their Affiliates and their
respective partners (both general and limited), members (both managing and otherwise), officers, directors, employees, agents and representatives (each such person being an “Indemnified Party”) from and against any and all actions,
suits, investigations, losses, claims, damages and liabilities, including in connection with seeking indemnification, whether joint or several (the “Liabilities”), related to, arising out of or in connection with the Services or
other services contemplated by this Agreement or the engagement of the Advisors pursuant to, and the performance by the Advisors of the Services or other services contemplated by, this Agreement, whether or not pending or threatened, whether or not
an Indemnified Party is a party, whether or not resulting in any liability and whether or not such action, claim, suit, investigation or proceeding is initiated or brought by the Company. The Company will reimburse any Indemnified Party for all
reasonable costs and expenses (including reasonable attorneys’ fees and expenses and any other litigation-related expenses) as they are incurred in connection with investigating, preparing, pursuing, defending or assisting in the defense of any
action, claim, suit, investigation or proceeding for which the Indemnified Party would be entitled to indemnification under the terms of the previous sentence, or any action or proceeding arising therefrom, whether or not such Indemnified Party is a
party thereto. The Company agrees that it will not, without the 

  

 6 








 
prior written consent of the Indemnified Party, settle, compromise or consent to the entry of any judgment in any pending or threatened claim, action or
proceeding relating to the matters contemplated hereby (if any Indemnified Party is a party thereto or has been threatened to be made a party thereto) unless such settlement, compromise or consent includes an unconditional release of the Indemnified
Party from all liability, without future obligation or prohibition on the part of the Indemnified Party, arising or that may arise out of such claim, action or proceeding, and does not contain an admission of guilt or liability on the part of the
Indemnified Party. The Company will not be liable under the foregoing indemnification provision with respect to any particular loss, claim, damage, liability, cost or expense of an Indemnified Party that is determined by a court, in a final judgment
from which no further appeal may be taken, to have resulted solely from the gross negligence or willful misconduct of such Indemnified Party. The attorneys’ fees and other expenses of an Indemnified Party shall be paid by the Company as they
are incurred upon receipt, in each case, of an undertaking by or on behalf of the Indemnified Party to repay such amounts if it is finally judicially determined that the Liabilities in question resulted solely from the gross negligence or willful
misconduct of such Indemnified Party. 
 The rights of an Indemnified Party to indemnification hereunder will be in addition to any other
rights and remedies any such person may have under any other agreement or instrument to which each Indemnified Party is or becomes a party or is or otherwise becomes a beneficiary or under any law or regulation.

believes reasonably appropriate to rendering the Services and other services contemplated by this Agreement and to comply with the Securities and Exchange Commission or other legal requirements relating to the beneficial ownership by the Advisors or
their Affiliates of equity securities of the Company (all such information so furnished, the “Information”). The Company recognizes and confirms that the Advisors (a) will use and rely primarily on the Information and on
information available from generally recognized public sources in performing the Services and other services contemplated by this Agreement without having independently verified the same, (b) do not assume responsibility for the accuracy or
completeness of the Information and such other information and (c) are entitled to rely upon the Information without independent verification. 
 Section 8. Term. This Agreement will become effective as of the Effective Time and (except as otherwise provided herein) will continue until the “Termination Date,” which is the earliest of (i) the
tenth anniversary of the date hereof, (ii) such time as the Affiliated Investors beneficially own less than 5% of the total common equity of the Company in the aggregate, (iii) with respect to any Advisor, such Advisor’s Affiliated
Investors no longer hold at least 50% of the Units acquired by such Advisor’s Affiliated Investors on the date hereof and (iii) such earlier date as the Company and the Advisors may mutually agree upon in writing; provided, that
(x) the occurrence of the Termination Date will not affect the obligations of the Company to pay, or cause to be paid, any amounts accrued but not yet paid as of such date, (y) Section 5 hereof will remain in effect after the
Termination Date with respect to Out-of-Pocket Expenses that were incurred prior to or within a reasonable period of time after the Termination Date, but which have not been paid to the Advisors in accordance with Section 5 hereof, and
(z) the provisions of Sections 4(e), 4(g), 4(h), 6, 7, 9 and 10 hereof will survive after the Termination Date. The Advisory Fee will accrue and be payable with respect to the entire fiscal year of the Company in which the Termination Date

recognition that the Advisors and their Affiliates currently have, and will in the future have or will consider acquiring, investments in numerous companies with respect to which the Advisors or their Affiliates may serve as an advisor, a director

investment funds or portfolio companies), on the other hand, may engage in the same or similar activities or lines of business and have an interest in the same areas of corporate opportunities, in recognition of the benefits to be derived by the
Company hereunder, and in recognition of the difficulties which may confront any advisor who desires and endeavors fully to satisfy such advisor’s duties in determining the full scope of such duties in any particular situation, the provisions
of this Section 9(b) are set forth to regulate, define and guide the conduct of certain affairs of the Company as they may involve the Advisors. Except as the Advisors may otherwise agree in writing after the date hereof:

limitation, any business activities or lines of business that are the same as or similar to those pursued by, or competitive with, the Company and its subsidiaries); (B) to directly or indirectly do business with any client or customer of the
Company and its subsidiaries; (C) to take any other action that the Advisor believes in good faith is necessary to or appropriate to fulfill its obligations as described in the first sentence of this Section 9(b); and (D) not to
present potential transactions, matters or business opportunities to the Company or any of its subsidiaries, and to pursue, directly or indirectly, any such opportunity for themselves, and to direct any such opportunity to another person.

 (ii) The Advisors and their Affiliates shall have no duty (contractual or otherwise) to communicate or present any
corporate opportunities to the Company or any of its affiliates or to refrain from any actions specified in Section 9(b)(i) hereof, and the Company, on its own behalf and on behalf of its affiliates, hereby irrevocably waives any right to
require the Advisors or any of its Affiliates to act in a manner inconsistent with the provisions of this Section 9(b). 
 (iii) Neither the Advisors nor any of their Affiliates shall be liable to the Company or any of its affiliates for breach of any duty (contractual or otherwise) by reason of any activities or omissions of the types referred to in this
Section 9(b) or of any such person’s participation therein. 
  

 8

the Advisors and their Affiliates and their respective partners (both general and limited), members (both managing and otherwise), officers, directors, employees, agents and representatives from any and all liabilities, claims and causes of action
in connection with the Services or other services contemplated by this Agreement or the engagement of the Advisors pursuant to, and the performance by the Advisors of the Services or other services contemplated by, this Agreement that the Company
may have, or may claim to have, on or after the date hereof, except with respect to any act or omission that constitutes gross negligence or willful misconduct as determined by a final, non-appealable determination of a court of competent
jurisdiction. 
 (d) Limitation of Liability. In no event will the Advisors or any of their Affiliates be liable to the Company or any
of its affiliates for any indirect, special, incidental or consequential damages, including, without limitation, lost profits or savings, whether or not such damages are foreseeable, or for any third-party claims (whether based in contract, tort or
otherwise), relating to, in connection with or arising out of this Agreement, including, without limitation, the services to be provided by the Advisors or any of their Affiliates hereunder, or for any act or omission that does not constitute gross
negligence or willful misconduct as determined by a final, non-appealable determination of a court of competent jurisdiction or in excess of the fees actually received by the Advisors hereunder.

waiver or consent will be effective only in the specific instance and for the specific purpose for which given. The waiver by any party of any breach of this Agreement will not operate as or be construed to be a waiver by such party of any
subsequent breach.
