Such assistance shall include (a) your providing, and using your commercially reasonable efforts to cause the Acquired Business and its advisors to provide, the Commitment Parties upon request with all information reasonably deemed necessary by the Lead Arrangers to complete such syndication, including, but not limited to, information, evaluations and projections prepared by you, the Acquired Business and its subsidiaries and your and their advisors, or on your or their behalf, or as may be reasonably requested by the Lead Arrangers, relating to the Transaction (including the Projections (as hereinafter defined), the “Information”), (b) assisting in the preparation of Information Memoranda and other materials to be used in connection with the syndication of the Facilities (collectively with the Summary of Terms and any additional summary of terms prepared for distribution to Public Lenders (as hereinafter defined), the “Information Materials”), (c) using your commercially reasonable efforts to ensure that the syndication efforts of the Lead Arrangers benefit materially from your existing lending relationships and the existing banking relationships of the Acquired Business, (d) using your commercially reasonable efforts to procure ratings for the Facilities from each of Standard & Poor’s, a division of The McGraw-Hill Companies, Inc.

Notwithstanding the Lead Arrangers’ right to syndicate the Facilities and receive commitments with respect thereto, it is understood that any syndication of, or receipt of commitments in respect of, all or any portion of any Commitment Party’s respective commitment hereunder prior to the initial funding of the Facilities shall not reduce any Commitment Party’s respective commitment hereunder. In addition, neither the commencement nor the completion of the syndication of any of the Facilities shall be a condition precedent to any of the commitments or undertakings of the Commitment Parties set forth in this Commitment Letter.

It is understood and agreed that the Lead Arrangers will manage and control all aspects of the syndication of the Facilities in consultation with you, including decisions as to the selection of prospective Lenders and any titles offered to proposed Lenders, when commitments will be accepted, the final allocations of the commitments among the Lenders, selecting counsel for the Lenders and negotiating the definitive documentation for the Facilities.

You agree to furnish us with further and supplemental information from time to time until the Closing Date and, if requested by us, for such period (not to exceed 90 days) thereafter as is necessary to complete the syndication of the Facilities so that the representation, warranty and covenant in the immediately preceding sentence are correct on the Closing Date and on such later date on which the syndication of the Facilities is completed as if the Information were being furnished, and such representation, warranty and covenant were being made, on such date. In issuing their respective commitments and in arranging and syndicating the Facilities, you recognize and confirm that each of the Commitment Parties (i) is and will be using and relying on the Information and the Projections without independent verification thereof, (ii) does not assume responsibility for the accuracy or completeness of the Information or the Projections and such other information and (iii) will not make an appraisal of any assets or liabilities of any of the Companies. The Information and Projections provided to the Lead Arrangers prior to the date hereof are hereinafter referred to as the “Pre-Commitment Information”.

You acknowledge that (a) the Commitment Parties on your behalf will make available Information Materials to the proposed syndicate of Lenders by posting the Information Materials on IntraLinks or another similar electronic system and (b) certain prospective Lenders (such Lenders, “Public Lenders”; all other Lenders, “Private Lenders”) may have personnel that do not wish to receive material non-public information (within the meaning of the United States federal securities laws, “MNPI”) with respect to the Companies, their respective affiliates or any other entity, or the respective securities of any of the foregoing, and who may be engaged in investment and other market-related activities with respect to the Companies’ securities. If requested, you will assist us in preparing an additional version of the Information Materials not containing MNPI (the “Public Information Materials”) to be distributed to prospective Public Lenders.

Before distribution of any Information Materials (a) to prospective Private Lenders, you shall provide us with a customary letter authorizing the dissemination of the Information Materials and (b) to prospective Public Lenders, you shall provide us with a customary letter authorizing the dissemination of the Public Information Materials and confirming the absence of MNPI therefrom. In addition, at our request, you shall identify Public Information Materials by clearly and conspicuously marking the same as “PUBLIC”.

You agree that the Commitment Parties on your behalf may distribute the following documents to all prospective Lenders, unless you advise the Commitment Parties in writing (including by email) within a reasonable time prior to their intended distributions that such material should only be distributed to prospective Private Lenders: (a) administrative materials for prospective Lenders such as lender meeting invitations and funding and closing memoranda, (b) notifications of changes to the Facilities’ terms and (c) other materials intended for prospective Lenders after the initial distribution of the Information Materials, including drafts and final versions of definitive documents with respect to the Facilities. If you advise us that any of the foregoing items should be distributed only to Private Lenders, then the Commitment Parties will not distribute such materials to Public Lenders without further

discussions with you. You agree (whether or not any Information Materials are marked “PUBLIC”) that Information Materials made available to prospective Public Lenders in accordance with this Commitment Letter shall not contain MNPI.

5. Fees and Indemnities. By executing this Commitment Letter, you agree, if the Closing Date occurs, to reimburse the Commitment Parties on demand for all reasonable out-of-pocket fees and expenses (including, but not limited to, (a) the reasonable fees, disbursements and other charges of Fried Frank Harris Shriver & Jacobson LLP, as counsel to the Lead Arrangers and the Administrative Agent, and of any special and local counsel to the Lenders retained by or on behalf of the Lead Arrangers or the Administrative Agent and (b) due diligence expenses (including the reasonable fees, disbursements and other charges of Latham & Watkins LLP in connection therewith)) incurred in connection with the Facilities, the syndication thereof and the preparation of the Commitment Letter and the definitive documentation therefor, and with any other aspect of the Transaction, any similar transaction and any of the other transactions contemplated hereby.

You also agree to indemnify and hold harmless each Commitment Party and each Lender and each of their affiliates and their respective officers, directors, employees, agents, advisors and other representatives (each an “Indemnified Party”) from and against (and will reimburse each Indemnified Party as the same are incurred for) any and all claims, damages, losses, liabilities and expenses (including, without limitation, the reasonable fees, disbursements and other charges of counsel) that may be incurred by or asserted or awarded against any Indemnified Party, in each case arising out of or in connection with or by reason of (including, without limitation, in connection with any investigation, litigation or proceeding or preparation of a defense in connection therewith) (a) any aspect of the Transaction or any similar transaction and any of the other transactions contemplated thereby or (b) the Facilities and any other financings, or any use made or proposed to be made with the proceeds thereof except to the extent such claim, damage, loss, liability or expense is found in a final, nonappealable judgment by a court of competent jurisdiction to have resulted from such Indemnified Party’s or its affiliates’ gross negligence, willful misconduct or bad faith. In the case of an investigation, litigation or proceeding to which the indemnity in this paragraph applies, such indemnity shall be effective whether or not such investigation, litigation or proceeding is brought by you, your equityholders or creditors or an Indemnified Party, whether or not an Indemnified Party is otherwise a party thereto and whether or not any aspect of the Transaction is consummated. You also agree that no Indemnified Party shall have any liability (whether direct or indirect, in contract or tort or otherwise) to you or your subsidiaries or affiliates or to your or their respective equity holders or creditors or to any other person or entity arising out of, related to or in connection with any aspect of the Transaction, except to the extent of direct (as opposed to special, indirect, consequential or punitive) damages determined in a final nonappealable judgment by a court of competent jurisdiction to have resulted from such Indemnified Party’s or its affiliates’ gross negligence, willful misconduct or bad faith.

In respect of any judgment or order given or made for any amount due hereunder that is expressed and paid in a currency other than U.S. dollars (the “Judgment Currency”), you will indemnify each of the Commitment Parties against any loss incurred by them as a result of any variation as between (a) the rate of exchange at which the U.S. dollar amount is converted into the Judgment Currency for the purpose of such judgment or order and (b) the rate of exchange at which such Commitment Party is able to purchase U.S. dollars with the amount of the Judgment Currency actually received by it. The foregoing indemnity shall constitute a separate and independent obligation of you, shall survive any termination of the commitments hereunder and shall continue in full force and effect notwithstanding any such judgment or order as aforesaid. The term “rate of exchange” shall include any premiums and costs payable in connection with the purchase of or conversion into U.S. dollars.
