EAGLEPICHER INCORPORATED ANNOUNCES
THAT IT IS EXTENDING ITS TENDER OFFER FOR
ITS 9?% SENIOR SUBORDINATED NOTES TO 11:59 P.M. ON AUGUST 6, 2003

Phoenix, Arizona, August 4, 2003 – EaglePicher Incorporated (“EPI”), a wholly-owned subsidiary of EaglePicher Holdings, Inc. (the “Company”), announced today that it has extended the expiration date of its cash tender offer for its 9 3/8% Senior Subordinated Notes Due 2008 (the “Notes”) to 11:59 p.m. on August 6, 2003. The tender offer was originally scheduled to expire at 11:59 p.m. on August 5, 2003.

EPI is seeking to acquire any and all of its outstanding $220 million of Notes pursuant to the terms and conditions set forth in its Offer to Purchase and Consent Solicitation Statement dated July 9, 2003 (the “Statement”). On July 23, 2003, EPI announced that it had received 95% of the $220 million of outstanding Notes and had executed a supplemental indenture amending its indenture among EPI, certain guarantors named therein, and The Bank of New York, as trustee. The supplemental indenture will not become operative until the Notes are accepted for purchase in accordance with the terms of the Statement. The tender offer will expire at 11:59 p.m., New York City time, on August 6, 2003, unless extended by EPI.

EPI intends to finance the tender offer and consent solicitation with the proceeds of an offering of approximately $250 million aggregate principal amount of senior unsecured notes pursuant to Rule 144A and Regulation S under the Securities Act of 1933, as amended (the “Securities Act”), together with other available funds. The securities to be offered 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 such registration requirements. Additionally, EPI is currently negotiating a new senior secured credit facility in the approximate amount of $275 million to replace its current credit facility. The new credit facility is anticipated to provide for a term loan of $150 million and a revolving facility of $125 million.

Requests for assistance relating to the terms and conditions of the tender offer may be directed to UBS Securities LLC, the Dealer Manager, at (203) 719-4210 (collect).
