(1)	Mr. Pratt is currently a beneficiary of the David C. Pratt Irrevocable Grantor Retained Annuity Trust dated 12/1/92. Mr. Pratt has no participation in voting or investment decisions with respect to trust assets. The trust currently holds 1,400,000 shares of the issuer's common stock and a $20,000,000 floating rate convertible subordinated note of the issuer that is convertible into 1,250,000 shares of the issuer's common stock on August 16, 2005. For purposes of Section 16 of the Securities Exchange Act of 1934, securities held by the trust are deemed to be beneficially owned by Mark R. Gale (as the sole owner and controlling person of Calco, Inc. which is the trustee of the trust). Although Mr. Pratt has no voting or investment power over the trust, Messrs. Pratt and Gale acknowledge, without so admitting, that they could be deemed to constitute a "group" with respect to the trust's investments in the issuer. Mr. Pratt and Mr. Gale are not related by blood or marriage.
