 Exhibit 4.1 
  
 EXECUTION COPY 
  
 THIRD AMENDMENT dated as of August 4, 2004 (this “Amendment”), to the CREDIT AGREEMENT dated as of August 29, 2001, as
heretofore amended by the Second Amendment dated as of July 8, 2003 and the Amendment and Waiver dated as of November 25, 2002 (the “Credit Agreement”), among AMERISOURCEBERGEN CORPORATION (the “Borrower”); the
LENDERS from time to time party thereto, and JPMORGAN CHASE BANK, as Administrative Agent (in such capacity, the “Administrative Agent”), as an Issuing Bank and as Swingline Lender. 
  
 The Borrower has requested that the Credit Agreement be amended so as (a) to
permit the Borrower to repurchase shares of its capital stock for aggregate consideration not to exceed $500,000,000 and, in connection therewith, to allow the Borrower to add back the aggregate amount of payments in respect of such repurchases when
determining compliance with the Minimum Tangible Net Worth covenant, (b) to permit the Borrower to redeem certain convertible subordinated notes and (c) to increase the amount of Capital Expenditures permitted between October 1, 2004 and the Term
Maturity Date. The undersigned Lenders are willing to amend the Credit Agreement as set forth herein. Capitalized terms used but not otherwise defined herein shall have the meanings assigned to them in the Credit Agreement. 
  
 Accordingly, in consideration of the mutual agreements herein contained and
other good and valuable consideration, the sufficiency and receipt of which are hereby acknowledged, the parties hereto agree as follows: 
  
 SECTION 1. Amendment of Credit Agreement. (a) Paragraph (a) of Section 6.08 of the Credit Agreement is hereby amended by deleting the word
“and” from before “(iv)” in the first sentence thereof and inserting the following before the period at the end of that first sentence: “and (v) notwithstanding the limitation in subsection (iv) above, so long as no Default
or Event of Default shall have occurred and be continuing at the time of a repurchase and no Default or Event of Default would occur as a result of making a repurchase, the Borrower may repurchase its capital stock to the extent that the aggregate
amount of all such payments in respect of such repurchases shall not exceed $500,000,000, in addition to any repurchases allowed under subsection (iv) above.” 
  
 (b) Paragraph (b) of Section 6.08 of the Credit Agreement is hereby amended by deleting the word
“and” at the end of subsection (iv), replacing the period at the end of subsection (v) with “; and” and inserting the following: “(vi) the conversion of 5% Convertible Subordinated Notes issued by Amerisource Health
Corporation (now known as AmerisourceBergen Services Corporation) due December 1, 2007 to, or the exchange of such Notes for, common stock of the Borrower, or the redemption of such Notes for cash pursuant to a notice of redemption given at a time
when no Default or Event of Default shall have occurred and be continuing (or would occur as a result of the redemption of all 







 such Notes for cash) and under circumstances in which it would reasonably be expected that the holders of
such Notes would elect to convert them to common stock of the Borrower prior to the redemption date.” 
  
 (c) Section 6.14 of the Credit Agreement is hereby amended by deleting the word “and” before “(ii)” and inserting the
following before the period at the end of the first sentence thereof: “and (iii) to the extent that the Borrower repurchases its capital stock as permitted under Section 6.08(a)(v), the lesser of the aggregate amount of all payments in respect
of such repurchases and $500,000,000.” 
  
 (d) Section 6.15 of the Credit Agreement is hereby amended by replacing the number “$150,000,000” each of the two times that it appears therein with the numbers “$275,000,000” and “$250,000,000”, respectively.
As amended, the final two rows of the table in Section 6.15 shall read as follows: 
  

				
	 October 1, 2004 through September 30, 2005
	  	$	275,000,000
		
	 October 1, 2005 through the Term Maturity Date.
	  	$	250,000,000

  
 SECTION 2.
Representations and Warranties. The Borrower represents and warrants to the Lenders as of the date hereof that: 
  
 (a) Before and after giving effect to this Amendment, the representations and warranties set forth in the Credit Agreement are true and
correct in all material respects with the same effect as if made on the Effective Date (as defined in Section 3), except to the extent such representations and warranties expressly relate to an earlier date, in which case such representations and
warranties are true and correct in all material respects as of such earlier date. 
  
 (b) At the time of and after giving effect to this Amendment, no Default has occurred and is continuing.

effective as of the date first written above (the “Effective Date”) at such time as the following condition shall have been satisfied (or waived in accordance with Section 9.02 of the Credit Agreement): The Administrative Agent (or
its counsel) shall have received from the Borrower, the Required Lenders and the Administrative Agent either (i) counterparts of this Amendment signed on behalf of such parties or (ii) written evidence satisfactory to the Administrative Agent (which

 The Administrative Agent shall notify the Borrower and the Lenders in writing of the Effective Date, and such notice shall be conclusive and binding.








 SECTION 4. Effect of Amendment. Except as expressly set forth herein, this Amendment shall not by
implication or otherwise limit, impair, constitute an amendment of, or otherwise affect the rights and remedies of the Lenders, the Administrative Agent or the Borrower under the Credit Agreement or any other Loan Document, and shall not alter,
modify, amend or in any way affect any of the terms, conditions, obligations, covenants or agreements contained in the Credit Agreement or any other Loan Document, all of which are ratified and affirmed in all respects and shall continue in full

other Loan Document in similar or different circumstances. This Amendment shall apply and be effective only with respect to the provisions of the Credit Agreement specifically referred to herein. This Amendment shall constitute a “Loan

for the Administrative Agent. 
  
 SECTION 6. Counterparts.
This Amendment may be executed in any number of counterparts and by different parties hereto on separate counterparts, each of which when so executed and delivered shall be deemed an original, but all of which when taken together shall constitute a
single instrument. Delivery of an executed counterpart of a signature page of this Amendment by facsimile transmission shall be as effective as delivery of a manually executed counterpart hereof. 
  
 SECTION 7. Applicable Law. THIS AMENDMENT SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. 
  
 SECTION 8. Headings. The headings of this Amendment are for purposes of reference only and shall not limit or otherwise affect the meaning hereof.
