Capitalized terms used but not defined herein are used with the meanings assigned to them on the Exhibits attached hereto (such Exhibits, together with this letter, collectively, the “Commitment Letter”). 1. Commitments In connection with the Transactions, JPMorgan is pleased to advise you of its commitment to provide, and hereby commits to provide, 100% of the aggregate amount of the First Lien Facilities (together with any other credit facilities the proceeds of which are used to finance the transactions on terms to be agreed, the “Senior Secured Facilities”), upon the terms and conditions set forth in this letter and Exhibits B and C hereto (collectively, the “Term Sheets”). 2. Titles and Roles It is agreed that: (a) (i) JPMorgan will act as sole lead arranger and sole bookrunner for the First Lien Facilities and any other credit facilities the proceeds of which are used to finance the transactions on terms to be agreed (acting in such capacities, the “First Lien Lead Arranger”); provided that the Company agrees that JPMorgan may perform its responsibilities hereunder through its affiliate, J.P. Morgan Securities LLC (“JPMS”) and (ii) JPMorgan (and as applicable, any of JPMorgan’s designated affiliates, including, without limitation, J.P.

Syndication We intend to syndicate the Senior Secured Facilities to a group of lenders identified by us in consultation with you (together with JPMorgan, the “Lenders”). The Commitment Party intends to commence syndication efforts promptly, and you agree actively to assist (and to use your commercially reasonable efforts to cause the Target to actively assist) the Commitment Party in completing a syndication satisfactory to the Commitment Party. Such assistance shall include, prior to the earlier of (a) 120 days following the Closing Date and (b) the date on which a Successful Syndication (as defined in the Arranger Fee Letter) is achieved (A) your using commercially reasonable efforts to ensure that the syndication efforts benefit from your and your affiliates’, the Target’s and the Target’s affiliates’ existing banking relationships, (B) direct contact between your senior management and advisors and the proposed Lenders (and using your commercially reasonable efforts to ensure such contact between senior management of the Target and the proposed Lenders), (C) your preparing and providing to the Commitment Party all information, including financial information, with respect to you and your subsidiaries (and using your commercially reasonable efforts to cause the Target to prepare and provide information, including financial information, with respect to the Target and its subsidiaries) and the Acquisition, including Projections (as defined below), as the Commitment Party may reasonably request in connection with the arrangement and syndication of the Senior Secured Facilities and your assistance (and using your commercially reasonable efforts to cause the Target to assist) in the preparation of one or more confidential information memoranda (each, a “Confidential Information Memorandum”) and other marketing materials to be used in connection with the syndication (all such information, memoranda and material, “Information Materials”), (D) your hosting, with the Commitment Party, of one or more meetings of prospective Lenders at times and locations to be mutually agreed (and using your commercially reasonable efforts to cause the officers of the Target to be available for such meetings), (E) your using your commercially reasonable efforts to obtain (x) indicative corporate credit and/or corporate family ratings for you (after giving effect to the Transactions) and (y) ratings for the Senior Secured Facilities, in each case from each of Moody’s Investors Service, Inc.

Upon the request of the Commitment Party, you will use your commercially reasonable efforts to furnish and to cause the Target to furnish, for no fee, to the Commitment Party an electronic version of your or Target’s, as applicable, trademarks, service marks and corporate logos for use in marketing materials for the purpose of facilitating the syndication of the Senior Secured Facilities (the “License”), including for purposes of posting copies thereof to a deal site on IntraLinks™, DebtDomain, SyndTrak, ClearPar or any other electronic platform

3 chosen by the Commitment Party to be its electronic transmission system (an “Electronic Platform”); provided, however, that the License shall be used solely for the purpose described above and may not be assigned or transferred. You also understand and acknowledge that we may provide to market data collectors, such as league table, or other service providers to the lending industry, information regarding the closing date, size, type, purpose of, and parties to, the Senior Secured Facilities. Notwithstanding any other provision of this Commitment Letter to the contrary and notwithstanding any syndication, assignment or other transfer by the Commitment Party, (a) the Commitment Party shall not be relieved, released or novated from its obligations hereunder (including its obligation to fund its applicable percentage of any First Lien Facility on the Closing Date if the conditions set forth on Exhibits B and C are satisfied or waived by Commitment Party) in connection with any syndication, assignment or other transfer until after the initial funding of Commitment Party’s commitment under such First Lien Facility on the Closing Date, (b) no such syndication, assignment or other transfer shall become effective with respect to any portion of Commitment Party’s commitments in respect of any First Lien Facility until the initial funding in full of such First Lien Facility on the Closing Date and (c) unless the Borrower agrees in writing in its sole discretion, Commitment Party shall retain exclusive control over all rights and obligations with respect to its commitments in respect of each First Lien Facility, including all rights with respect to any consent, waiver, modification, supplement and/or amendment, until the Closing Date has occurred. The Commitment Party will manage, in consultation with you, all aspects of the syndication, including decisions as to the selection of institutions to be approached and when they will be approached, when commitments will be accepted, which institutions will participate, the allocation of the commitments among the Lenders and the amount and distribution of fees among the Lenders. You hereby acknowledge and agree that the Commitment Party will have no responsibility other than to arrange the syndication as set forth herein and in no event shall the Commitment Party be subject to any fiduciary or other implied duties in connection with the transactions contemplated hereby. At the request of the Commitment Party, you agree to assist in the preparation of a version of each Confidential Information Memorandum or other Information Material (a “Public Version”) consisting exclusively of information with respect to you and your subsidiaries, the Target and its subsidiaries and the Acquisition that is either publicly available (or would be publicly available if the Target was a public reporting company) or not material with respect to you and your subsidiaries, the Target and its subsidiaries, any of your or the Target’s respective securities or the Acquisition for purposes of United States federal and state securities laws (such information, “Non-MNPI”). Such Public Versions, together with any other information prepared by you or the Target or your or its affiliates or representatives and conspicuously marked “Public” (collectively, the “Public Information”), which at a minimum means that the word “Public” will appear prominently on the first page of any such information, may be distributed by us to prospective Lenders who have advised us that they wish to receive only Non-MNPI (“Public Side Lenders”). You acknowledge and agree that, in addition to Public Information and unless you promptly notify us otherwise, (a) drafts and final definitive documentation with respect to the Senior Secured Facilities, (b) administrative materials prepared by the Commitment Party for prospective Lenders (such as a lender meeting invitation, allocations and funding and closing memoranda) and (c) notifications of changes in the terms of the Senior Secured Facilities may be distributed to Public Side Lenders. You acknowledge that the Commitment Party’s public-side employees and representatives who are publishing debt analysts may participate in any meetings held pursuant to clause (D) of the second preceding paragraph; provided that such analysts shall not publish any information obtained from such meetings (i) until the syndication of the Senior Secured Facilities has been completed upon the making of allocations by the First Lien Lead Arranger and the First Lien Lead Arranger freeing the Senior Secured Facilities to trade or (ii) in violation of any confidentiality agreement between you or the Target and the Commitment Party.

4 In connection with our distribution to prospective Lenders of any Confidential Information Memorandum and, upon our request, any other Information Materials, you will execute and deliver to us a customary authorization letter authorizing such distribution and, in the case of any Public Version thereof or other Public Information, representing that it only contains Non-MNPI. Each Confidential Information Memorandum will be accompanied by a disclaimer exculpating you and us with respect to any use thereof and of any related Information Materials by the recipients thereof. Notwithstanding the foregoing, neither the commencement nor the completion of syndication of the Senior Secured Facilities shall be a condition to the availability of the First Lien Facilities on the Closing Date. The Commitment Party acknowledges that the Company, as part of the syndication of the Senior Secured Facilities, would like to increase the amount of the Revolving Facility to $100 million subject to the receipt of sufficient commitments from Lenders pursuant to such syndication efforts (it being understood that the commitment under this Commitment Letter to provide the Revolving Facility is limited to $60 million) (such increased amount, the “Additional Revolving Amount”). 4. Information You hereby represent and warrant that with respect to any information relating to you, or to your knowledge, any information relating to the Target and its subsidiaries (a) all information (including all Information Materials), other than the Projections and information of a general economic or industry specific nature (the “Information”), that has been or will be made available to us by you or any of your representatives in connection with the transactions contemplated hereby, when taken as a whole, does not or will not, when furnished to us, contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements contained therein not materially misleading in light of the circumstances under which such statements are made (giving effect to all supplements thereto) and (b) the financial projections and other forward-looking information (the “Projections”) that have been or will be made available to us by you or any of your representatives in connection with the transactions contemplated hereby have been or will be prepared in good faith based upon assumptions believed by you to be reasonable at the time furnished to us (it being recognized by the Commitment Party that such Projections are not to be viewed as facts and that actual results during the period or periods covered by any such Projections may differ from the projected results, and such differences may be material). You agree that if, at any time prior to the Closing Date and thereafter until completion of our syndication efforts, you become aware that any of the representations in the preceding sentence would be incorrect if such Information or Projections were furnished at such time and such representations were remade, in any material respect, then you will (or, with respect to the Information and Projections relating to the Target and its subsidiaries, will use commercially reasonable efforts to) promptly supplement the Information and the Projections so that (with respect to Information and Projections relating to the Target and its subsidiaries, to your knowledge) such representations when remade would be correct, in all material respects, under those circumstances. You understand that in arranging and syndicating the Senior Secured Facilities we may use and rely on the Information and Projections without independent verification thereof. 5. Fees As consideration for the commitments and agreements of the Commitment Party hereunder, you agree to pay or cause to be paid the nonrefundable fees described in the Arranger Fee Letter, dated the date hereof and delivered herewith (the “Arranger Fee Letter”) and the Administrative Agent Fee Letter, dated the date hereof and delivered herewith (the “Administrative Agent Fee Letter” and together with the Arranger Fee Letter, the “Fee Letters”), in each case, on the terms and subject to the conditions set forth therein.

5 You agree that, once paid, the fees or any part thereof payable hereunder or under the Fee Letters shall not be refundable under any circumstances, regardless of whether the transactions or borrowings contemplated by this Commitment Letter are consummated, except as otherwise agreed in writing by you and JPMorgan.
