The commitments of the GS Principal Investors are several, and not joint. No GS Principal Investor is or will be responsible for the obligations of any other GS Principal Investor.

NOTWITHSTANDING ANYTHING CONTAINED HEREIN OR IN THE TERM SHEET TO THE CONTRARY, NEITHER HPS NOR ANY GS PRINCIPAL INVESTOR IS ACTING AS AN UNDERWRITER, ARRANGER, TRUSTEE, AGENT OR IN A SIMILAR ROLE OR IS OTHERWISE PERFORMING ANY SERVICES HEREUNDER AND THE ROLE OF EACH OF HPS AND EACH GS PRINCIPAL INVESTOR UNDER THIS COMMITMENT LETTER SHALL BE LIMITED TO THEIR COMMITMENTS TO PROVIDE DEBT FINANCING AS A PRINCIPAL.

Each of the parties hereto agrees that (i) this Commitment Letter is a binding and enforceable agreement with respect to the subject matter contained herein, subject without limitation to the satisfaction (or waiver by each party hereto) of the conditions precedents set forth herein and an agreement of each party to negotiate in good faith the First Lien Facilities Documentation by the parties hereto in a manner consistent with this Commitment Letter, it being acknowledged and agreed that the commitment provided hereunder is subject only to conditions precedent as expressly provided herein, and (ii) the Closing Payment Letter is a legally valid and binding agreement of the parties thereto with respect to the subject matter set forth therein.

Each of the parties hereto agrees that service of process, summons, notice or document by registered mail addressed to you or us at the addresses set forth above shall be effective service of process for any suit, action or proceeding brought in any such court.

Each of the Commitment Parties hereby notifies you that, pursuant to the requirements of the USA PATRIOT Act, Title III of Pub. L. 107-56 (signed into law October 26, 2001) (as amended, the “PATRIOT Act”) and the requirements of 31 C.F.R §1010.230 (the “Beneficial Ownership Regulation”), it and each Lender is required to obtain, verify and record information that identifies the Borrower and each Guarantor, which information includes names, addresses, tax identification numbers and other information that will allow such Commitment Party and such Lender to identify the Borrower and each Guarantor in accordance with the PATRIOT Act and the Beneficial Ownership Regulation.

You hereby acknowledge and agree that the Commitment Parties shall be permitted to share any or all such information with the Lenders.

The indemnification, compensation (if applicable), reimbursement (if applicable), jurisdiction, governing law, venue, waiver of jury trial and confidentiality provisions contained herein and in the Closing Payment Letter and the provisions of Section 8 of this Commitment Letter shall remain in full force and effect regardless of whether the First Lien Facilities Documentation shall be executed and delivered and notwithstanding the termination or expiration of this Commitment Letter or the Initial Lenders’ commitments hereunder; provided that your obligations under this Commitment Letter (except as specifically set forth in the penultimate sentence of Section 4 of this Commitment Letter, and other than your obligations with respect to the confidentiality of this Commitment Letter, the Closing Payment Letter and the contents hereof and thereof) shall automatically terminate and be superseded, in each case to the extent covered thereby, by the provisions of the First Lien Facilities Documentation upon the initial funding thereunder, and you shall automatically be released from all liability in connection therewith at such time. You may terminate this Commitment Letter and the Initial Lenders’ commitments with respect to the First Lien Facilities hereunder at any time subject to the provisions of the preceding sentence.

13

reduce or terminate the Initial Lenders’ commitments with respect to any or all of the First Lien Facilities (on a pro rata basis amongst the applicable Initial Lenders), in each case, in a manner consistent with the allocation of purchase price reduction described under paragraph 1 of Exhibit C regardless of whether or not such reduction or termination is made in connection with a purchase price reduction.

In the case of any such capitalized term that is subject to multiple and differing definitions, the appropriate meaning thereof in this Exhibit A shall be determined by reference to the context in which it is used.

Merger Sub, formed at the direction of Sycamore Partners Management, L.P. and its affiliates and funds, partnerships or other co-investment vehicles managed, advised or controlled by the foregoing (collectively, the “Sponsor”), intends to merge with and into a corporation previously identified to you as “Wing” (the “Company”). Merger Sub intends to consummate the Merger (as defined below) pursuant to an Agreement and Plan of Merger, dated as of the date hereof (together with all exhibits, annexes, schedules and other disclosure letters thereto, collectively, as modified, amended, supplemented, consented to or waived, the “Merger Agreement”) by and among Merger Sub, the other parties party thereto and the Company, pursuant to which (i) Merger Sub will merge with and into the Company (the “Merger”), with the Company being the surviving entity of the Merger and (ii) except with respect to certain equity holders who are contemplated to be immediately reinvesting the proceeds received by them as consideration in the Merger indirectly in the Borrower (as defined below) and other entities holding the other businesses of the Company in exchange for equity interests in such entities (the “Reinvestment Investors”), the equity holders of the Company will receive cash and certain contingent value rights in exchange for their capital stock and/or equity awards in the Company (collectively, the “Merger Consideration”).

In addition, it is intended that the Sponsor will establish (i) a newly formed corporation, limited liability company and/or partnership (the “Parent Holdco”), (ii) a newly created company organized under the laws of the United States and a direct or indirect wholly-owned subsidiary of Parent Holdco (“Holdings”) and (iii) a newly created entity treated for U.S. federal income tax purposes as a corporation (or disregarded entity whose regarded parent is a corporation) organized under the laws of the United States and a wholly-owned direct subsidiary of Holdings (the “Borrower”) that will, concurrently with, or no earlier than 1 business day prior to the consummation of the Merger, directly or indirectly acquire from the Company the Specialty Pharmacy Business (as defined below) in accordance with, and as provided for, in Section 1.3(d) of the Merger Agreement (the “Specialty Pharmacy Acquisition”). “Specialty Pharmacy Business” shall mean the “Shields Interests” (as defined in Schedule 6.16 to the Merger Agreement).

In connection with the foregoing, it is intended that:

(a) The Sponsor and certain other investors (including management of the Company and the Reinvestment Investors) arranged by and/or designated by the Sponsor (collectively with the Sponsor, the “Investors”), financial institutions or capital providers, will directly or indirectly make cash contributions to the Parent Holdco (the net proceeds of which will be contributed by the Parent Holdco, directly or indirectly, to Holdings in the form of (i) common equity and/or (ii)(A) preferred equity having terms reasonably satisfactory to each Commitment Party and/or (B) a bridge facility incurred by the Parent Holdco in lieu thereof having terms reasonably satisfactory to each Commitment Party (it being understood that the terms provided to the Commitment Parties on or prior to the date hereof are satisfactory) (any such equity or bridge facility issued in lieu thereof, together, “Permitted Equity”); provided that at least $2,000 million of Permitted Equity (such minimum, the “Third Party Minimum”) will be contributed to Holdings on the Closing Date from a nationally reputable third party provider on terms reasonably satisfactory to the Commitment Parties (it being understood that the nationally reputable third party providers and terms provided to the Commitment Parties on or prior to the date hereof are satisfactory) (such third party or bridge providers, the “Third Party Providers”), in an aggregate amount equal to, when combined with the fair market value of any capital stock of any of the management, founders and other existing direct or

A-1

indirect equity holders of the Company and its subsidiaries rolled over or invested in connection with the Transactions (as defined below) (together, the “Equity Contribution”) at least 50% (the “Minimum Equity Percentage”) of the sum of (1) the aggregate principal amount of the First Lien Facilities actually funded on the Closing Date, excluding the gross proceeds of any Revolving Loans to fund (A) working capital needs and (B) original issue discount and/or upfront fees plus (2) the Equity Contribution on the Closing Date in respect of Holdings and its subsidiaries on the Closing Date after giving effect to the Transactions.

(c) The Borrower will obtain a $2,500 million aggregate principal amount senior secured term loan facility described in Exhibit B to the Commitment Letter (the “Term Facility”) and (ii) a $100 million aggregate principal amount revolving credit facility described in Exhibit B to the Commitment Letter (the “Revolving Facility” and, together with the Term Facility, the “First Lien Facilities”).

The proceeds of the Equity Contribution, the First Lien Facilities borrowed on the Closing Date and cash on hand at the Company and its subsidiaries on the Closing Date will be applied (i) as described above to pay the consideration in connection with the Specialty Pharmacy Acquisition and (ii) to pay the fees and expenses incurred in connection with the Transactions (such fees and expenses, the “Transaction Costs”) (the amounts set forth in clauses (i) through (ii) above, collectively, the “Transaction Consideration”). The transactions described above (including the payment of Transaction Costs) are collectively referred to herein as the “Transactions”. For purposes of the Commitment Letter and the Closing Payment Letter, “Closing Date” shall mean the date of the initial funding under the First Lien Facilities. After giving effect to the Transactions, the Parent Holdco will own, directly or indirectly, 100% of the issued and outstanding equity interests of Holdings and, on the Closing Date, the Sponsor will, directly or indirectly, control the voting capital stock having at least a majority of the ordinary voting power for the election of the board of directors or equivalent governing body of Holdings immediately after giving effect to the Transactions.

Capitalized terms used but not otherwise defined herein shall have the meanings assigned to them in the Credit Agreement. This certificate is furnished pursuant to Section [●] of the Credit Agreement.

Solely in my capacity as a financial executive officer of the Borrower and not individually (and without personal liability), I hereby certify, that as of the date hereof, after giving effect to the consummation of the Transactions:

1. The sum of the liabilities (including contingent liabilities) of the Borrower and its subsidiaries, on a consolidated basis, does not exceed the present fair saleable value of the present assets of the Borrower and its subsidiaries, on a consolidated basis.

2. The fair value of the property of the Borrower and its subsidiaries, on a consolidated basis, is greater than the total amount of liabilities (including contingent liabilities) of the Borrower and its subsidiaries, on a consolidated basis.

3. The capital of the Borrower and its subsidiaries, on a consolidated basis, is not unreasonably small in relation to their business as contemplated on the date hereof.

4. The Borrower and its subsidiaries, on a consolidated basis, have not incurred and do not intend to incur, or believe that they will incur, debts including current obligations beyond their ability to pay such debts as they become due (whether at maturity or otherwise).

For purposes of this Certificate, the amount of any contingent liability has been computed as the amount that, in light of all of the facts and circumstances existing as of the date hereof, represents the amount that would reasonably be expected to become an actual or matured liability.

IN WITNESS WHEREOF, I have executed this Certificate this as of the date first written above.
