Item 5.  Other Events.
         ------------

         On November 12, 2002, AmerisourceBergen Corporation (the "Company")
announced that it is planning to issue $275 million senior notes due 2012 in a
private placement. A copy of the press release is filed as Exhibit 99.1 to this
report and incorporated herein by reference.

         In connection with the issuance of senior notes, the Company expects to
disclose to prospective purchasers certain information that has not been
previously publicly reported. A copy of such information is attached as Exhibit
99.2 to this report and incorporated herein by reference.

         Certain information contained in this report includes forward-looking
statements (as defined in Section 27A of the Securities Act and Section 21E of
the Exchange Act) that reflect the Company's current views with respect to
future events and financial performance. These statements are based on
management's current expectations and are subject to uncertainty and changes in
circumstances. Actual results may vary materially from the expectations
contained in the forward-looking statements. Forward-looking statements may
include statements addressing future financial and operating results of
the Company and the benefits and aspects of the 2001 merger between
AmeriSource Health Corporation and Bergen Brunswig Corporation.

         The following factors, among others, could cause actual results to
differ materially from those described in the forward-looking statements: the
risk that the businesses of AmeriSource and Bergen Brunswig will not be
integrated successfully; failure to obtain and retain expected synergies; and
other economic, business, competitive and/or regulatory factors affecting the
business of AmerisourceBergen generally. More detailed information about these
factors is set forth in AmerisourceBergen's filings with the Securities and
Exchange Commission, including its Annual Report on Form 10-K for fiscal 2001,
its Quarterly Reports on Form 10-Q for fiscal 2002, and the joint proxy
statement-prospectus for the merger filed on August 1, 2001. The Company is



under no obligation to (and expressly disclaims any such obligation to) update
or alter any forward-looking statements whether as a result of new information,
future events or otherwise.

amended, the Registrant has duly caused this report to be signed on its behalf
