Certain defined terms that are used but not otherwise defined herein have the meanings given to such terms in Section 10.

WHEREAS, Transaction Services (as defined herein) have been rendered since 11 May 2010 and shall continue to be rendered to the Company and certain of its Subsidiaries and Affiliates (each, a “Beneficiary Affiliate”) in connection with the transactions contemplated by, and consequential upon, the Acquisition Agreement and future transactions;

WHEREAS, the Company hereby confirms its wish to retain the Advisor, and the Advisor confirms its wish to be retained, to provide the Transaction Services to the Company and to each of the Beneficiary Affiliates; and

NOW, THEREFORE, in consideration of the premises and mutual covenants contained herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties to this Agreement hereby agree as follows:

1. Term. This Agreement shall be in effect for an initial term commencing on the Effective Date and ending on the tenth (10th) anniversary thereof (the “Term”), which initial term shall be automatically extended thereafter on a year-to-year basis unless the Advisors provide written notice of the desire to terminate this Agreement to the Company at least ninety (90) days prior to the expiration of the Term or any extension thereof. Notwithstanding anything to the contrary in this Agreement, this Agreement may be terminated prior to the tenth (10th) anniversary of the Effective Date upon (i) a willful material breach of this Agreement by a party which is not cured within thirty (30) days of receipt of a written notice from the other party requiring cure, (ii) the earlier of (A) consummation of a Change of Control, or (B) an Initial Public Offering (and in each case this Agreement shall terminate automatically without further act of the parties), (iii) written agreement of the Company and the Advisor, or (iv) the Advisor otherwise serving a written termination notice on the Company. The provisions of Sections 6 to 20 (inclusive) shall survive any termination of this Agreement.

2. Transaction Services. The parties hereto agree that certain transaction-specific services, as further described below (collectively, the “Transaction Services”) shall be performed from the Effective Date for the benefit of the Company and the Beneficiary Affiliates. The Transaction Services provided may be evidenced by documentation to be agreed upon between the Company and the Advisor. The Transaction Services shall be provided in connection with the transactions described in Sections 3(a) and 3(b), and may include, without limitation, the following:

(a) advice and support relating to the identification, negotiation and analysis of specific acquisitions and dispositions by any of the Company or the Beneficiary Affiliates, including, without limitation, any share, asset or debt purchase or disposition;

(b) advice and support relating to the negotiation of transaction-specific financing (and consideration of financing alternatives), including, without limitation, in connection with acquisitions, capital expenditures and refinancing of existing indebtedness;

(c) other advice relating to transaction-specific finance , including assistance in the preparation of financial projections and monitoring of compliance with financing agreements;

(f) other transaction-specific services for the Company or the Beneficiary Affiliates upon which the boards of directors of the Company and the Advisor agree.

Legal services will not be provided by the Advisor. The Transaction Services will be conducted in support of the members of management and boards of directors of the Company and the Beneficiary Affiliates and, for the avoidance of doubt, such services shall be considered provided by outside consultants, not managers, of the Company and the Beneficiary Affiliates. Pursuant to this Agreement, the Advisor shall not have any authority or power to commit the Company and/or its Subsidiaries to any contracts with third parties.

In consideration for Transaction Services performed from the Effective Date for the Company or the Beneficiary Affiliates, the Company hereby agrees to pay (or to procure that any one or more Beneficiary Affiliates shall pay), the following transaction fees (collectively, the “Transaction Fees”):

(a) In connection with the consummation of the Acquisition and transactions consequential thereon, the Company agrees to pay (or shall procure that any one or more of the Beneficiary Affiliates shall pay) a transaction fee in an aggregate amount equal to fifteen million United States Dollars (US$15,000,000) plus VAT (if applicable). In addition, the Company will reimburse the Advisor or its designee, by wire transfer of immediately available funds on the Effective Date, for its reasonable travel expenses and other reasonable out of pocket fees and expenses (including without limitation the fees and expenses of accountants, attorneys and other advisors retained by the Advisor) incurred in connection with the investigation, negotiation, and consummation of the Acquisition.

(b) In connection with (i) the consummation of each acquisition (other than the Acquisition) including, without limitation, any share, asset or debt purchase, (ii) the consummation of each divestiture including, without limitation, any share, asset or debt divestiture, (iii) the provision of advice to management regarding each transaction that results in a Change of Control of the Company or any Beneficiary Affiliate, and/or (v)

debt or equity financing, by, of or involving the Company or any Beneficiary Affiliates, the Company agrees to pay (or shall procure that a Beneficiary Affiliate shall pay), to the extent lawfully permitted, an aggregate transaction fee in an amount equal to one percent (1%) of the aggregate consideration for such transaction (in each case, whether such transaction is by way of merger, purchase or sale of stock or other securities, purchase or sale or other disposition of assets or debt, recapitalization, reorganization, consolidation, tender offer, public offering, or otherwise and whether consummated directly by the Company and/or any of the Beneficiary Affiliates or indirectly by, of or involving any of their respective equity owners or corporate parents), plus VAT in each case where it is applicable.

All Transaction Fees shall be paid by wire transfer in cash or other immediately available funds to the account(s) designated by the Advisor.

4. Recharge of Fees. The Advisor acknowledges that the Company may recharge to the Beneficiary Affiliates such proportion of the Transaction Fees that it pays and as relates to the benefit provided to such Beneficiary Affiliates by the relevant Transaction Services. The Advisor shall, if requested, provide the Company and the Beneficiary Affiliates with such evidence as they may reasonably request of the Transaction Services provided for the benefit of the Company and such Beneficiary Affiliates.

5. Personnel.

6. Liability. None of the Advisor or its Affiliates (or their respective members, managers, affiliates, officers, controlling persons, fiduciaries, employees and agents in their capacity as such) (collectively, the “Advisor’s Group”) shall be liable to any of the Company or the Beneficiary Affiliates for any Loss arising out of or in connection with the performance of the Transaction Services contemplated by this Agreement. The Advisor makes no representations or warranties, express or implied, in respect of the Transaction Services. Except as the Advisor may otherwise agree in writing after the date hereof: (a) each member of the Advisor’s 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 any of the Beneficiary Affiliates or (ii) do business with any client or customer of the Company or any of the Beneficiary Affiliates; (b) no member of the Advisor’s Group shall be liable to the Company or any of the Beneficiary Affiliates for breach of any duty (contractual or otherwise) by reason of any the activities referenced in (i) above or of such member’s participation therein; and (c) in the event that any member of the Advisor’s Group acquires knowledge of a potential transaction or matter that may constitute an opportunity (or potential opportunity) for any of the Company or the Beneficiary Affiliates, no member of the Advisor’s Group shall have any duty (contractual or otherwise) to communicate or present such corporate opportunity to the

Company or any of the Beneficiary Affiliates, and, notwithstanding any provision of this Agreement to the contrary, no member of the Advisor’s Group shall be liable to the Company or any of the Beneficiary Affiliates for breach of any duty (contractual or otherwise) by reason of the fact that any member of the Advisor’s 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 or any of the Beneficiary Affiliates. In no event will any member of the Advisor’s Group be liable to any of the Company or any of the Beneficiary Affiliates for any 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) third party Claims (whether based in contract, tort or otherwise) but excluding Claims under Section 7.

7. Indemnity.

For purposes of this Section 7, none of the circumstances described in the limitations contained in the immediately preceding sentence shall be deemed to apply absent a final non-appealable judgment of a court of competent jurisdiction to such effect, in which case to the extent any such limitation is so determined to apply to any Indemnitee as to any previously advanced indemnity payments made by the Company, then such payments shall be promptly repaid by such Indemnitee to the Company. The rights of any Indemnitee to indemnification hereunder will be in addition to any other rights any such person may have under any other agreement or instrument referenced above or any other agreement or instrument to which such Indemnitee is or becomes a party or is or otherwise becomes a beneficiary or under law or regulation. The Company hereby agrees that the Company is the indemnitor of first resort (i.e., its obligations to Indemnitees under this Agreement are primary and any obligation of the Advisor (or any Affiliate thereof) to provide advancement or indemnification for the same Indemnified Liabilities (including all interest, assessments and other charges paid or payable in connection with or in respect of such Indemnified Liabilities) incurred by Indemnitees are secondary), and if the Advisor or any Affiliate thereof pays or causes to be paid, for any reason, any amounts otherwise indemnifiable hereunder or under any other indemnification agreement (whether pursuant to contract, bylaws or charter) with any director or officer of the Company, then (i) the Advisor (or such Affiliate, as the case may be) shall be fully subrogated to all rights of Indemnitee with respect to such payment and (ii) the Company shall reimburse the

Advisor (or such Affiliate, as the case may be) for the payments actually made and waives any right of subrogation, reimbursement, exoneration, contribution or indemnification and any right to participate in any Claim or remedy of any Indemnitee against any Indemnitee, whether such Claim, remedy or right arises in equity or under contract, statute, common law or otherwise, including any right to claim, take or receive from any Indemnitee, directly or indirectly, in cash or other property or by set-off or in any other manner, any payment or security or other credit support on account of such Claim, remedy or right.

8. Severability. Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be invalid, illegal, or unenforceable in any respect under applicable law or rule in any jurisdiction, such invalidity, illegality, or unenforceability shall not affect the validity, legality, or enforceability of any other provision of this Agreement in such jurisdiction or affect the validity, legality, or enforceability of any provision in any other jurisdiction.
