You (“you” or the “Borrower”) have advised Bank of America, N.A. (“Bank of America”) and Merrill Lynch, Pierce, Fenner & Smith Incorporated (or any of its designated affiliates, “MLPFS” and, together with Bank of America, the “Commitment Parties”, “we” or “us”) that you, directly or indirectly through one of your wholly-owned domestic subsidiaries (such subsidiary, the “Merger Sub”), intend to acquire (the “Acquisition”) a company previously identified to us and code named “Kansas” (the “Acquired Business”) and to consummate the other Transactions. Such Acquisition will be effected through (i) the purchase of shares of the common stock of the Acquired Business by the Merger Sub in the “Offer” (as defined in the Acquisition Agreement) and (ii) on the Closing Date (as defined below), promptly following the closing of the Offer, the merger (the “Merger”) of Merger Sub with and into the Acquired Business pursuant to Section 251(h) of the Delaware General Corporation Law, with the Target surviving such Merger as your direct or indirect wholly-owned subsidiary. In connection therewith, the Borrower intends to obtain a 364-day senior unsecured bridge term loan credit facility (the “Bridge Facility”) in an aggregate principal amount of up to $2,100,000,000 (as such amount may be reduced as set forth in the Term Sheet). The date of consummation of the Acquisition, Offer and Merger (and the date on which the Bridge Facility shall be available) is referred to herein as the “Closing Date.”

In connection with the foregoing, (a) Bank of America is pleased to advise you of its commitment to provide the full principal amount of the Bridge Facility (in such capacity, the “Initial Lender”) and its willingness to act as the sole and exclusive administrative agent (in such capacity, the “Administrative Agent”) for the Bridge Facility, all upon and subject to the terms and conditions set forth in this letter and in Exhibits A and B hereto (collectively, the “Term Sheet” and, together with this letter agreement, the “Commitment Letter”), (b) MLPFS is pleased to advise you of its willingness, and you hereby engage MLPFS, to act as the sole and exclusive lead arranger and sole and exclusive bookrunner (in such capacity, the “Lead Arranger”) for the Bridge Facility, and in connection therewith to form a syndicate of lenders for the Bridge Facility subject to your consent to the extent expressly set forth herein (not to be unreasonably withheld or delayed) (collectively, the “Lenders”), including Bank of America. You further agree that no other titles will be awarded and no compensation (other than that expressly contemplated by this Commitment Letter and the Fee Letter referred to below) will be paid in order to obtain commitments in connection with the Bridge Facility unless you and we shall so agree. The commitments of the Initial Lender in respect of the Bridge Facility and the undertaking of the Lead Arranger to provide the services described herein are subject solely to the satisfaction (or waiver) of each of the

conditions precedent set forth on Exhibit B and upon the satisfaction (or waiver) of such conditions, the funding of the Bridge Facility shall occur. All capitalized terms used and not otherwise defined herein shall have the same meanings as specified therefor in the Term Sheet.

1.Syndication. The Lead Arranger intends to commence syndication of the Bridge Facility promptly after your acceptance of the terms of this Commitment Letter and the Fee Letter (as hereinafter defined) (which syndication shall not reduce the commitment of the Initial Lender hereunder, except as provided for in Section 8) and you agree to use commercially reasonable efforts to provide us with a period of at least 20 consecutive days following the date hereof and prior to the Closing Date to syndicate the Bridge Facility. Until the earlier of 90 days following the Closing Date and the completion of a Successful Syndication (as defined in the Fee Letter (as defined below)) (such earlier date, the “Syndication Date”), you agree to actively assist, and to use your commercially reasonable efforts to cause the Acquired Business and its subsidiaries to actively assist, the Lead Arranger in achieving a Successful Syndication (as defined in the Fee Letter). Such assistance shall include (a) your providing and causing your advisors to provide, and using your commercially reasonable efforts to cause the Acquired Business, their subsidiaries and their advisors to provide, the Lead Arranger (for distribution to Lenders and prospective Lenders) upon request with all information reasonably deemed necessary by the Lead Arranger to complete such syndication, (b) your assistance in the preparation of an information memorandum with respect to the Bridge Facility in form and substance customary for transactions of this type and otherwise reasonably satisfactory to the Lead Arranger (each, an “Information Memorandum”) and other materials to be used in connection with the syndication of the Bridge Facility (collectively with the Term Sheet and any additional summary of terms prepared for distribution to Public Lenders (as hereinafter defined), the “Information Materials”), (c) your using your commercially reasonable efforts to ensure that the syndication efforts of the Lead Arranger benefit materially from your existing lending relationships and the existing banking relationships of the Acquired Business, (d) your using commercially reasonable efforts to procure or maintain monitored Public Debt Ratings from two of (i) Moody’s Investors Service, Inc. (“Moody’s”), (ii) Standard & Poor’s Financial Services LLC (“S&P”) and (iii) Fitch, Inc. (“Fitch”), (e) your using commercially reasonable efforts to execute and deliver the Credit Documentation (as hereinafter defined) or, if applicable, one or more Joinder Agreements (as hereinafter defined), in each case as soon as reasonably practicable following commencement of syndication of the Bridge Facility and (f) your making your officers and advisors, and using your commercially reasonable efforts to make the officers and advisors of the Acquired Business, available to attend and make presentations at a reasonable number of meetings with prospective Lenders at times to be mutually agreed.

In order to facilitate an orderly and successful syndication of the Bridge Facility, you agree that until the Syndication Date, the Borrower and its subsidiaries will not, and will use commercially reasonable efforts to cause the Acquired Business and its subsidiaries to not, issue, announce, offer, place or arrange debt securities or any syndicated credit facilities of the Borrower or its subsidiaries (other than (i) the Senior Notes, (ii) a Qualifying Term Loan Facility agreed by the Lead Arranger, (iii) the extension of, increase of the commitments under or, to the extent agreed by the Lead Arranger, other amendment, refinancing or replacement of the Existing Revolving Facility; provided, no such extension, increase, amendment, refinancing or replacement shall cause or permit more than $900,000,000 of aggregate commitments to be outstanding under the Existing Revolving Facility (or any amendments, replacements or refinancings thereof) without our express written consent, (iv) any debt or financing permitted to be incurred by the Acquired Business pursuant to the Merger Agreement and (v) any other financing agreed by the Lead Arranger), in each case if such issuance, announcement, offering, placement or arrangement could reasonably be expected to materially impair the primary syndication of the Bridge Facility.

Notwithstanding anything to the contrary contained in this Commitment Letter or the Fee Letter or any other letter agreement or undertaking concerning the financing of the Transactions to the contrary, (i) none of the paragraphs of this Section 2 shall constitute a condition to the commitments

hereunder or the funding of the Bridge Facility on the Closing Date (except to the extent also set forth in Section 5 hereof or Exhibit B hereto) and (ii) the Commitment Parties’ commitments hereunder are not subject to the commencement or completion of a syndication of the Bridge Facility or to receipt of any Public Debt Ratings from Moody’s, S&P or Fitch.

It is understood and agreed that the Lead Arranger will manage and control all aspects of the syndication of the Bridge Facility in consultation with you, including decisions as to the selection of prospective Lenders (subject to your consent, to the extent expressly set forth herein, not to be unreasonably withheld or delayed) and any titles offered to proposed Lenders, when commitments will be accepted and the final allocations of the commitments among the Lenders. 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 Term Sheet and Fee Letter.

If you advise us that any of the foregoing items should be distributed only to Private Lenders, then the Lead Arranger will not distribute such materials to Public Lenders without further discussions with you. You agree that Information Materials made available to prospective Public Lenders in accordance with this Commitment Letter shall not contain MNPI.

You also agree that no Indemnified Party shall have any liability (whether direct or indirect, in contract or tort or otherwise) to you, the Acquired Business or your or their subsidiaries or affiliates or to your or their respective equity holders or creditors or any other person arising out of, related to or in connection with any aspect of the Transactions, except to the extent of direct (as opposed to special, indirect, consequential or punitive) damages determined in a final, non-appealable judgment by a court of competent jurisdiction to have resulted from such Indemnified Party’s gross negligence or willful misconduct. It is further agreed that the Commitment Parties shall only have liability to you (as opposed to any other person), and that the Commitment Parties shall be severally liable solely in respect of their respective commitments to the Bridge Facility, on a several, and not joint, basis with any other Lender.

The undersigned hereby certifies as follows:

1.I am the chief financial officer of the Borrower.

2.I have reviewed the terms of the Credit Agreement and the definitions and provisions contained in the Credit Agreement relating thereto and, in my opinion, have made, or have caused to be made under my supervision, such examination or investigation as is necessary to enable me to express an informed opinion as to the matters referred to herein.

3.Based upon my review and examination described in paragraph 2 above, I certify on behalf of the Borrower and its Subsidiaries, on a consolidated basis, that, as of the date hereof and after giving effect to the Transactions and the other transactions contemplated by the Credit Agreement:

(i)The sum of the “fair value” of the assets of the Borrower and its Subsidiaries, taken as a whole, exceeds the sum of all debts of the Borrower and its Subsidiaries, taken as a whole, as such quoted terms are determined in accordance with applicable federal and state laws governing determinations of the insolvency of debtors.

(ii)The “present fair saleable value” of the assets of the Borrower and its Subsidiaries, taken as a whole, is greater than the amount that will be required to pay the probable liability on debts of the Borrower and its Subsidiaries, taken as a whole, as such debts become absolute and matured, as such quoted term is determined in accordance with applicable federal and state laws governing determinations of the insolvency of debtors.

(iii)The capital of the Borrower and its Subsidiaries, taken as a whole, is not unreasonably small in relation to the business in which they are or are about to become engaged.

(iv)The Borrower and its Subsidiaries, taken as a whole, do not intend to incur, or believe that they will incur, debts beyond their ability to pay as they mature.

(v)The Borrower and its Subsidiaries, taken as a whole, are presently able to pay their debts as such debts mature.

For purposes of clauses (i) through (v) above, (a) (i) “debt” means liability on a “claim” and (ii) “claim” means any (x) right to payment, whether or not such a right is reduced to judgment, liquidated, unliquidated, fixed, contingent, matured, unmatured, disputed, undisputed, legal, equitable, subordinated, secured or unsecured or (y) right to an equitable remedy for breach of performance if such breach gives rise to a right to payment, whether or not such right to an equitable remedy is reduced to judgment, fixed, contingent, matured or unmatured, disputed, undisputed, secured or unsecured and (b) the amount of any contingent, unliquidated and disputed claim and any claim that has not been reduced to judgment at any time has been computed as the amount that, in light of all the facts and circumstances existing at such time, represents the amount that can reasonably be expected to become an actual or matured liability (irrespective of whether such liabilities meet the criteria for accrual under the Financial Accounting Standards Board Statement of Financial Accounting Standards No. 5).

This certificate is being signed by the undersigned in [his/her] capacity as chief financial officer of the Borrower and not in [his/her] individual capacity.

IN WITNESS WHEREOF, the undersigned has executed this Certificate as of the date first written above.
