PharMerica, Inc. Initiates Cash Tender Offer and Consent Solicitation for Its 8.375% Senior Subordinated Notes Due 2008

July 17, 2001

The purchase price for each $1,000 principal amount of Notes tendered pursuant to the Offer is $1,010, plus accrued and unpaid interest on the purchased Notes up to, but not including, the payment date. The consent payment for each $1,000 principal amount of Notes for which a consent is validly delivered during the consent solicitation period is $5.00. Holders who tender their Notes are required to give their consent in the consent solicitation. Any holder tendering notes after the consent solicitation period but prior to the expiration of the tender offer period will not be entitled to receive the consent payment.

This tender offer is expected to remain open until 9:00 A.M. EDT on August 14, 2001. The consent solicitation is expected to remain open until the later of 5:00 P.M. EDT on July 27, 2001 or until consents are received from holders of a majority (in principal amount) of the outstanding Notes (but no later than the expiration of the tender offer period). PharMerica will issue a further press release regarding any extension of these times and dates. Tenders of Notes and deliveries of consents become irrevocable after the consent solicitation period expires, unless the offer is subsequently terminated without any Notes being purchased.

The tender offer and consent solicitation are contingent upon a number of conditions, including: obtaining consents from holders of a majority (in principal amount) of the outstanding Notes to the removal of substantially all of the restrictive covenants in the governing indenture; consummation of the previously announced "merger-of-equals" transaction between Bergen Brunswig and AmeriSource Health Corporation; consummation of a bond financing by the combined AmeriSource-Bergen Corporation yielding net proceeds of at least $300.0 million; execution of a supplemental indenture containing the proposed amendments; and other general and customary conditions. The bond financing condition is itself contingent upon the consummation of the Bergen Brunswig AmeriSource merger. No assurance can be given that any of these conditions will be satisfied. Since PharMerica is a wholly owned subsidiary of Bergen Brunswig, no filings are required to be made with the Securities and Exchange Commission in connection with this tender offer and consent solicitation.

The terms of the tender offer and consent solicitation are more fully described in the Offer to Purchase and Consent Solicitation Statement, which is dated July 17, 2001. The offering statement and related documents provide additional information regarding the pricing, tender, consent and delivery procedures, as well as conditions of the tender offer and consent solicitation.

On April 26, 1999, Bergen Brunswig acquired PharMerica, Inc. in a tax-free merger transaction, in which PharMerica became a wholly owned subsidiary of Bergen Brunswig. Under the terms of that merger, stockholders of PharMerica received Bergen Brunswig's Class A Common Stock in exchange for their outstanding shares of PharMerica common stock, which, at the time, was traded on the Nasdaq National Market System under the symbol: DOSE. As a result of that merger, PharMerica ceased to be subject to the SEC's reporting requirements, but it remains obligated to provide certain financial reports to the trustee under the Notes' indenture.
