(ii)           AMERISOURCEBERGEN DRUG CORPORATION (“ABDC”), as Servicer (in such capacity, the “Servicer”), and as Originator (in such capacity, the “Originator”);

(v)           THE BANK OF TOKYO-MITSUBISHI UFJ, LTD., NEW YORK BRANCH (“BTMU”), as the new “Administrator” under the Receivables Purchase Agreement (in such capacity, the “New Administrator”).

BACKGROUND

A.            Seller, the Servicer, the Purchaser Groups and the Prior Administrator are parties to that certain Amended and Restated Receivables Purchase Agreement, dated as of April 29, 2010 (as amended, supplemented or otherwise modified prior to the date hereof, the “Receivables Purchase Agreement”).

B.            On the terms and conditions set forth herein, the Amerisource Parties have requested that the Prior Administrator transfer and assign to the New Administrator, and the New Administrator desires to accept and assume from the Prior Administrator, all of the Prior Administrator’s rights and obligations under the Receivables Purchase Agreement and each of the other Transaction Documents.

C.            The Amerisource Parties have advised the Prior Administrator that they desire to voluntarily prepay on the date hereof all outstanding indebtedness, fees and other obligations owing to Bank of America under the Receivables Purchase Agreement and each of the other Transaction Documents.

NOW, THEREFORE, the parties hereto hereby agree as follows:

SECTION 1.         Definitions.  Capitalized terms used in this Agreement and not otherwise defined herein shall have the meanings assigned thereto in, or by reference in, the Receivables Purchase Agreement.

SECTION 2.         Assignment and Assumption.

(a)           Assignment and Assumption.  Effective as of the Effective Time (as defined below), the Prior Administrator hereby transfers, sets over, assigns and conveys to the New Administrator all of the Prior Administrator’s right, title and interest in, and delegates all of its duties and obligations under, the Receivables Purchase Agreement and each of the other Transaction Documents.  From and after the Effective Time, the New Administrator hereby accepts such transfer and assignment to it, agrees to be bound by all of the terms and conditions of the Receivables Purchase Agreement and each of the other Transaction Documents to which it is a party, and unconditionally assumes all of the obligations of the Prior Administrator relating to the foregoing.

(b)           Financing Statements; Further Assurances.  In connection with the assignment and assumption contemplated by clause (a) above, each of the parties hereto hereby authorizes the New Administrator to file (or cause to be filed), at Seller’s sole expense, any UCC financing statements, financing statement amendments or similar filings that the New Administrator may reasonably consider necessary or desirable to assign to the New Administrator, any security interest or other rights, if applicable, granted or assigned to the Prior Administrator under the Transaction Documents.  Each of the parties hereto hereby agrees to do all such things and execute all such documents and instruments, at Seller’s sole expense, as the New Administrator may reasonably consider necessary or desirable (i) to give full effect to the assignment to the New Administrator by the Prior Administrator of the role of “Administrator” under the Receivables Purchase Agreement and the other Transaction Documents and (ii) to perfect and preserve the rights and powers of the New Administrator for itself and on behalf of the other Secured Parties under the Receivables Purchase Agreement and the other Transaction Documents.

(c)           Non-Reliance.  The Prior Administrator has not provided any information and makes no representation or warranty whatsoever and assumes no responsibility with respect to the Receivables or the financial condition of any Amerisource Party or the performance or observance by any Amerisource Party of their respective obligations under the Transaction Documents.  The New Administrator confirms that (i) it has independently and without reliance upon the Prior Administrator and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement and (ii) it has made and will continue to make its own appraisal of and investigation into (A) the business, operations, property, prospects, financial and other conditions and creditworthiness of each of the Amerisource Parties and (B) the Receivables.

(d)           Resignation of Prior Administrator.  From and after the Effective Time, the Prior Administrator shall cease to be a party to the Receivables Purchase Agreement and each of the other Transaction Document to which the Prior Administrator was a party in the capacity of “Administrator” and shall no longer have any rights or obligations under the Receivables Purchase Agreement or any other Transaction Document in its capacity as “Administrator” thereunder.

(i)            payment of the Payoff Amount on or prior to the Payoff Time constitutes satisfaction in full of all of the Amerisource Parties’ obligations to Bank of America under the Transaction Documents except for indemnification and other obligations of the Amerisource Parties which by their terms expressly survive termination of the Transaction Documents (such surviving obligations, the “Surviving Obligations”);

(ii)           all outstanding obligations of the Amerisource Parties to Bank of America under the Transaction Documents and all documents executed and/or delivered in connection therewith are released, discharged and satisfied (other than Surviving Obligations); and

(b)           To the extent that any consent of any party hereto is required under any other agreement to which it is a party for any of the transactions to be effected hereby, such party hereby grants such consent and waives any notice requirements or condition precedent to the effectiveness of any such transactions set forth in any agreement to which it is a party that has not been satisfied as of the date hereof (other than any requirements or conditions precedent set forth in this Agreement).
