Upon consummation of the tender offer and the determination of the actual payment date, the Company will determine the total consideration in accordance with the formula set forth in the above mentioned offer and solicitation statement using the yields set forth above for each of the respective notes. Assuming the payment date is September 14, 2005, the total consideration will be $1,103.04 for each $1,000 principal amount of 2008 Notes purchased in the tender offer, plus accrued and unpaid interest, if any, from the last interest payment date up to, but not including, the initial payment date. Assuming the initial payment date is September 14, 2005, the total consideration will be $1,166.37 for each $1,000 principal amount of 2012 Notes purchased in the tender offer, plus accrued and unpaid interest, if any, from the last interest payment date up to, but not including, the initial payment date.

The total consideration includes a consent payment of $30.00 per $1,000 principal amount of notes that is payable only to holders who validly tendered their notes on or before 5:00 p.m., EDT, on September 8, 2005. Holders who validly tendered their notes after 5:00 p.m., EDT, on September 8, 2005, but before the expiration of the tender offer, will be paid $1,073.04 per $1,000 principal amount of 2008 notes purchased in the tender offer or will be paid $1,136.37 per $1,000 principal amount of 2012 notes purchased in the tender offer, in either case plus accrued and unpaid interest, if any, from the last interest payment date up to, but not including, the final payment date.

As a result of the receipt of the requisite amount of consents in connection with the Company's tender offer and consent solicitation, AmerisourceBergen, the guarantor of both senior notes and J.P. Morgan Trust Company, as trustee, entered into a supplemental indenture dated September 8, 2005, relating to each series of senior notes. The supplemental indentures will become effective upon acceptance of the senior notes for purchase in the tender offer commenced on August 25, 2005. The supplemental indenture eliminates substantially all of the restrictive covenants and certain events of default contained in the original indenture, and modifies the defeasance and certain other provisions contained in the original indenture.

On September 8, 2005, AmerisourceBergen Corporation issued a news release announcing that it has agreed to sell two new senior notes in a private placement.

The 2012 senior notes and 2015 senior notes each will be sold at 99.5 percent of principal amount, resulting in an effective annual interest rate of 5.71 percent on the 2012 senior notes and an effective annual interest rate of 5.94 percent on the 2015 senior notes. The Company expects to complete the sale of the 2012 senior notes and the 2015 senior notes next week.
