AmeriSource Prices $250 Million Convertible Subordinated Note Offering

     VALLEY FORGE, PENNSYLVANIA - December 7, 2000 - AmeriSource Health
Corporation today announced that it has offered and priced a new issue of $250
million of Convertible Subordinated Notes due 2007. The notes will have an
annual interest rate of 5%, payable semi-annually, and will be convertible into
Class A Common Stock of the Company at approximately $52.97 per share. The
Company may also issue up to an additional $50 million of the notes pursuant to
an option that has been granted to the initial purchasers. The Company intends
to use the net proceeds from the sale of the notes to repay existing borrowings,
and for working capital and other general corporate purposes. The notes will
provide longer term, fixed rate debt at a lower cost than existing debt. The
notes are being issued in a private placement and are expected to be resold by
the initial purchasers to qualified institutional buyers under Rule 144A of the
Securities Act of 1933.

     The notes and the common stock issuable upon conversion of the notes have
not been registered under the Securities Act and may not be offered or sold in
the United States absent registration or an applicable exemption from the
registration requirements. This does not constitute an offer to sell or the
solicitation of an offer to buy any security in any jurisdiction in which such
offer or sale would be unlawful.
