IESI CORPORATION ANNOUNCES EXTENSION OF TENDER OFFER FOR ITS
10¹/₄% SENIOR SUBORDINATED NOTES DUE 2012

Fort Worth, TX—December 22, 2004—IESI Corporation (“IESI” or the “Company”) announced today that it has extended the expiration date for its previously announced tender offer for its 10¼% Senior Subordinated Notes due 2012 (the “Notes”) to 9:00 a.m., New York City time, on Friday, January 21, 2005 (unless extended). The Company also announced that the value of the consideration for each $1,000 principal amount of Notes validly tendered and accepted for purchase will be determined of 10:00 a.m., New York City time, on January 6, 2005, and will be calculated in accordance with the Offer to Purchase (as defined below).

The Company’s Offer to Purchase and Consent Solicitation Statement (the “Offer to Purchase”), dated November 29, 2004 , more fully sets forth the terms and conditions of the cash tender offer to purchase any and all of the $150,000,000 outstanding principal amount of the Notes and the consent solicitation to eliminate substantially all of the restrictive and reporting covenants, certain events of default and certain other provisions contained in the indenture governing the Notes. As of 5:00 p.m., New York City time, on December 21, 2004, the Company had received tenders and consents for approximately 98.2% of the outstanding principal amount of the Notes. The percentage of consents received exceeds the requisite consents needed to amend the indenture governing the Notes.

The Company reserves the right to extend the expiration date and time of the tender offer at any time subject to applicable law. In the event that the tender offer is extended for any period of time longer than ten business days from the previously scheduled expiration date, a new price determination date will be established that will be the tenth business day immediately preceding the expiration date as so extended.

The consummation of the tender offer is conditioned on, among other things, the closing of the Company’s previously announced merger, as described in more detail in the Offer to Purchase.
