The date on which the Bridge Facility is funded and the Acquisition is consummated is referred to as the “Funding Date”.

In connection with the foregoing, (a) Bank of America is pleased to offer, and you hereby engage Bank of America, to be the sole and exclusive administrative agent (in such capacity, the “Administrative Agent”), (b) Wells Fargo Bank is pleased to offer, and you hereby engage Wells Fargo Bank, to be the sole and exclusive Syndication Agent (in such capacity, the “Syndication Agent”), (c) Bank of America is pleased to advise you of its commitment to lend 50% of the aggregate principal amount of the Bridge Facility and Wells Fargo Bank is pleased to advise you of its commitment to lend 50% of the aggregate principal amount of the Bridge Facility (in such capacities, each, an “Initial Lender” and collectively, the “Initial Lenders”), and (d) BofA Securities and Wells Fargo Securities are pleased to offer, and you hereby engage BofA Securities and Wells Fargo Securities, to act as joint lead arrangers and joint bookrunners (in such capacities, each, a “Lead Arranger” and collectively, the “Lead Arrangers”) for the Bridge Facility and in connection therewith, to form a syndicate of financial institutions (the “Lenders”) reasonably acceptable to you for the Bridge Facility, in each case, upon and subject to the terms and conditions of this commitment letter (this commitment letter together with Exhibits A, B, C and D attached hereto, collectively, this “Commitment Letter”). It is understood and agreed that, (i) no additional agents, co-agents or arrangers will be appointed and no other titles will be awarded in connection with the Bridge Facility without the prior written approval of you and the Lead Arrangers, which shall not be unreasonably withheld or delayed,

(ii) BofA Securities will have “lead left” placement in all marketing materials or other documentation used in connection with the Bridge Facility, and (iii) the commitments of the Initial Lenders set forth in clause (c) of this paragraph are several and not joint.

Notwithstanding anything in this Commitment Letter, the Fee Letters, the Credit Documentation or any other letter agreement or other undertaking concerning the financing of the Transactions to the contrary, the commitments of the Initial Lenders in respect of the Bridge Facility and the undertaking of the Lead Arrangers to provide the services described herein are subject solely to the satisfaction (or waiver by the Initial Lenders) of the conditions expressly set forth in the Conditions Precedent to Closing attached hereto as Exhibit C and the conditions set forth in the Conditions Precedent to Funding attached hereto as Exhibit D (such conditions, collectively, the “Specified Conditions”), it being understood that there are no conditions (implied or otherwise) to the commitments hereunder (including, without limitation, compliance with the terms of this Commitment Letter, the Fee Letters and the Credit Documentation) other than the Specified Conditions, and upon satisfaction (or waiver thereof in accordance with the terms hereof and the Credit Documentation) of the Specified Conditions, the closing and funding of the Bridge Facility shall occur.

Notwithstanding anything in this Commitment Letter, the Fee Letters, the Credit Documentation or any other letter agreement or other undertaking concerning the financing of the Transactions to the contrary, (i) the only conditions (express or implied) to the closing of the Bridge Facility on the Closing Date are the Closing Conditions, (ii) the only conditions (express or implied) to the availability and funding of the Bridge Facility on the Funding Date are the Funding Conditions, (iii) the only representations the accuracy of which shall be a condition to the Closing Date and the availability of the Bridge Facility on the Funding Date shall be (A) the representations made by or with respect to the Acquired Company and its subsidiaries in the Acquisition Agreement as are material to the interests of the Lenders (in their capacities as such), but only to the extent that the Borrower or any of its subsidiaries has the right (taking into account any applicable cure provisions) to terminate (or not perform) its obligations under the Acquisition Agreement, or to decline to consummate the Acquisition pursuant to the Acquisition Agreement, as a result of an inaccuracy of such representations in the Acquisition Agreement (the “Acquisition Agreement Representations”) and (B) the Specified Representations (as defined below) and (iv) the terms of the Credit Documentation shall be in a form such that they do not impair (A) the closing of the Bridge Facility on the Closing Date or (B) the availability or funding of the Bridge Facility on the Funding Date if the Specified Conditions are otherwise satisfied (or waived by the Commitment Parties).

This paragraph shall be referred to herein as the “Limited Conditionality Provisions”.

connection with the Acquisition or the other Transactions contemplated by this Commitment Letter (including any such bank credit facility or other bank borrowings or commitments to refinance or replace the Bridge Facility but excluding, for the avoidance of doubt, the New Notes) or any similar transaction entered into during the twelve month period following the date hereof in which you or any of your affiliates acquires, directly or indirectly, all or any substantial portion of the stock or assets of the Acquired Companies (each a “Bank Financing”).

The Lead Arrangers intend to commence syndication of the Bridge Facility promptly, in the reasonable discretion of the Lead Arrangers, upon your acceptance of this Commitment Letter and the Fee Letters (as hereinafter defined). The Initial Lenders’ commitments hereunder shall be reduced dollar-for-dollar (with any such reduction applied ratably between the Initial Lenders in accordance with each Initial Lender’s commitment hereunder) as and when commitments for the Bridge Facility are received from Eligible Lenders (as defined below), to the extent that each such Eligible Lender becomes party to the Credit Documentation as a “Lender” (including, pursuant to an assignment and assumption agreement executed pursuant to the Credit Documentation) or otherwise party to this Commitment Letter pursuant to documentation reasonably satisfactory to the Lead Arrangers and you. Until the earlier of (a) the date upon which a Successful Syndication (as defined in the Arranger Fee Letter) is achieved and (b) the 60^th day following the Funding Date (the “Syndication Date”), you agree to use commercially reasonable efforts to actively assist, and to use your commercially reasonable efforts to cause the Acquired Company to actively assist to the extent consistent with the Acquisition Agreement, the Lead Arrangers in achieving a Successful Syndication. Such assistance shall include (i) your providing and causing your advisors to provide (and your using commercially reasonable efforts prior to the Funding Date to cause the Acquired Company and its advisors to provide to the extent consistent with the Acquisition Agreement) the Commitment Parties and the Lenders upon request with all customary information with respect to you and your subsidiaries, the Acquired Company and its subsidiaries and the Transactions reasonably deemed necessary by the Lead Arrangers to complete syndication, including, but not limited to, information and evaluations prepared by you, the Acquired Company and your and its advisors, or on your or its behalf, relating to the Transactions (including the Projections (as hereinafter defined), the “Information”), subject in all respects to the limitations on your rights to request such information concerning the Acquired Company and its subsidiaries as set forth in the Acquisition Agreement; (ii) your assisting (and your using commercially reasonable efforts prior to the Funding Date to cause the Acquired Company to assist to the extent consistent with the Acquisition Agreement) in the preparation of a customary confidential information memorandum, customary lender presentation and other customary marketing materials to be used in connection with the syndication of the Bridge Facility (collectively, the “Information Materials”), subject in all respects to the limitations on your rights to request such information concerning the Acquired Company and its subsidiaries as set forth in the Acquisition Agreement; (iii) your using commercially reasonable efforts to assist the Lead Arrangers such that their syndication efforts benefit from your existing banking relationships and, to the extent consistent with the Acquisition Agreement, the existing banking relationships of the Acquired Company; (iv) your agreeing that, until the Syndication Date, there shall be no competing offering, placement or arrangement of any debt securities or syndicated bank financing by or on behalf of the Borrower and its subsidiaries, in each case that would reasonably be expected to materially and adversely impair the primary syndication of the Bridge Facility (other than any Bank Financing, the proposed amendments to the Existing Credit Agreement, any borrowings under the Existing Credit Agreement, any indebtedness permitted to be incurred by the Acquired Company or its subsidiaries pursuant to the Acquisition Agreement, working capital facilities of foreign subsidiaries, the New Notes or any other financing agreed by the Lead Arrangers); and (v) your making your senior management and advisors available (and, upon the reasonable request of the Lead Arrangers, using commercially reasonable efforts prior to the Funding Date to make senior management of the Acquired Company available to the extent consistent with the Acquisition Agreement) from time to time to attend and make presentations

regarding the business of the Borrower and its subsidiaries and the Acquired Company and its subsidiaries, as appropriate, at one meeting of, or conference call with, prospective Lenders (or such additional meetings or conference calls as reasonably requested by the Lead Arrangers and agreed to by the Borrower), in all cases upon reasonable advance notice during normal business hours, and at times and locations to be mutually agreed. Without limiting your obligations to assist with syndication efforts as set forth above, and notwithstanding anything to the contrary in this Commitment Letter or in the Fee Letters, the Commitment Parties acknowledge and agree that neither the commencement nor the completion of the syndication of the Bridge Facility (including a Successful Syndication) nor any other provision of this paragraph shall constitute a condition precedent to the availability and funding of the Bridge Facility on the Funding Date.

It is understood and agreed that the Lead Arrangers will manage and control all aspects of the syndication of the Bridge Facility, in consultation with you (and subject to your agreement as provided herein), including decisions as to the selection of prospective Lenders and any titles offered to proposed Lenders, when commitments will be accepted and the final allocations of the commitments among the Lenders; provided, that, only potential Lenders that (a) are existing lenders under the Existing Credit Agreement, (b) on or before the 45^th day following the date hereof, are approved by the Borrower (such approval not to be unreasonably withheld or delayed), or (c) after the 45^th day following the date hereof, are identified by the Lead Arrangers in consultation with you, will be approached and permitted to participate in the syndication (any such potential Lender, an “Eligible Lender”). It is understood that no Lender participating in the Bridge Facility will receive compensation from you in order to obtain its commitment, except on the terms contained herein and in the Summary of Terms. It is also understood and agreed that the amount and distribution of the fees among the Lenders will be at the discretion of the Lead Arrangers in consultation with you, subject to the terms and provisions of the Arranger Fee Letter.

You hereby represent that (to your knowledge with respect to the Acquired Company and its subsidiaries) (a) all written Information concerning you and your subsidiaries and the Acquired Company and its subsidiaries, other than Projections (defined below) and other forward-looking information and information of a general economic or industry-specific nature, if any, furnished to us by you or any of your representatives (or on your or their behalf) in connection with the Transactions, taken as a whole, does not and will not contain any material misstatement of fact or omit to state a material fact necessary to make the statements contained therein, in light of the circumstances in which they were made, when taken as a whole, not materially misleading (after giving effect to all supplements and updates thereto from time to time), and (b) all financial projections concerning the Borrower and its subsidiaries and the Acquired Company and its subsidiaries furnished to us by you or any of your representatives (or on your or their behalf) in connection with the Transactions (the “Projections”) have been or will be prepared in good faith based upon assumptions you believe to be reasonable at the time such Projections are furnished to the Lead Arrangers (it being understood that Projections are subject to significant uncertainties and contingencies many of which are beyond your control, and no assurance can be given that the Projections will be realized, and that actual results may differ from projected results and that such differences may be material). You agree (or, prior to the Funding Date with respect to Information and Projections concerning the Acquired Company and its subsidiaries, you agree, subject to the limitations on your rights as set forth in the Acquisition Agreement, to use commercially reasonable efforts to) to furnish us with such Information and Projections as we may reasonably request and to supplement such Information and the Projections from time to time until the later of the Syndication Date and the Funding Date so that the representation in the preceding sentence is correct in all material respects on the later of the Syndication Date and the Funding Date as if the Information were being furnished, and such representation were being made, on such date. In issuing these commitments and in arranging and syndicating the Bridge Facility, the Commitment Parties are and will be using and relying on the Information and the Projections without independent verification thereof. Without limiting your obligations under this paragraph, it is understood that the Initial Lenders’ commitments with respect to the Bridge Facility hereunder are not conditioned upon the accuracy of, or your compliance with, the representations, warranties and covenants in this paragraph.

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, upon the request of the Commitment Parties, you shall provide us with a customary letter authorizing the dissemination of the Information Materials, which dissemination shall be subject to customary confidentiality undertakings satisfactory to you (it being understood and agreed that customary procedures employed by us for providing prospective Lenders access via IntraLinks, SyndTrak or another similar electronic system to information and other materials related to the Bridge Facility and the confidentiality terms to be accepted by prospective Lenders in connection therewith are reasonably satisfactory to you for such purpose) 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”.

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.

By executing this Commitment Letter, you agree to reimburse the Commitment Parties from time to time 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 Moore & Van Allen PLLC, as counsel to the Administrative Agent and BofA Securities, and, if necessary, of a single special and local counsel to the Lenders in each appropriate jurisdiction retained by the Lead Arrangers or the Administrative Agent, which fees, disbursements and charges shall in each case be documented in reasonable detail and not exceed the fees, disbursements and other charges actually billed by such counsel in connection therewith at their standard rates, (b) due diligence expenses and (c) all CUSIP fees for registration with the Standard & Poor’s CUSIP Service Bureau) incurred in connection with the Bridge Facility, the syndication thereof, the preparation of the Credit Documentation, the enforcement thereof and the other Transactions.

ANNEX I

FORM OF

SOLVENCY CERTIFICATE

This Solvency Certificate is delivered pursuant to Section [        ] of the Credit Agreement dated as of [            ], 20    , among [                    ] (the “Credit Agreement”). Capitalized terms used herein and not otherwise defined herein shall have the meanings assigned to such terms in the Credit Agreement.

The undersigned hereby certifies, solely in his capacity as an officer of the Borrower and not in his individual capacity, as follows:

1.     I am the Chief Financial Officer of the Borrower. I am familiar with the Transactions, and have reviewed the Credit Agreement, financial statements referred to in Section [        ] of the Credit Agreement and such documents and made such investigation as I have deemed relevant for the purposes of this Solvency Certificate.

2.     As of the date hereof, immediately after giving effect to the consummation of the Transactions, on and as of such date (i) the fair value of the assets of the Borrower and its subsidiaries on a consolidated basis, at a fair valuation, will exceed the debts and liabilities, direct, subordinated, contingent or otherwise, of the Borrower and its subsidiaries on a consolidated basis; (ii) the present fair saleable value of the property of the Borrower and its subsidiaries on a consolidated basis will be greater than the amount that will be required to pay the probable liability of the Borrower and its subsidiaries on a consolidated basis on their debts and other liabilities, direct, subordinated, contingent or otherwise, as such debts and other liabilities become absolute and matured; (iii) the Borrower and its subsidiaries on a consolidated basis will be able to pay their debts and liabilities, direct, subordinated, contingent or otherwise, as such debts and liabilities become absolute and matured; and (iv) the Borrower and its subsidiaries on a consolidated basis will not have unreasonably small capital with which to conduct the businesses in which they are engaged as such businesses are now conducted and are proposed to be conducted following the Funding Date.

3.     As of the date hereof, immediately after giving effect to the consummation of the Transactions, the Borrower does not intend to, and the Borrower does not believe that it or any of its subsidiaries will, incur debts beyond its ability to pay such debts as they mature, taking into account the timing and amounts of cash to be received by it or any such subsidiary and the timing and amounts of cash to be payable on or in respect of its debts or the debts of any such subsidiary.

This Solvency Certificate is being delivered by the undersigned officer only in his capacity as Chief Financial Officer of the Borrower and not individually and the undersigned shall have no personal liability to the Administrative Agent or the Lenders with respect thereto.
