ITEM 2.04   TRIGGERING EVENTS THAT ACCELERATE OR INCREASE A DIRECT FINANCIAL
            OBLIGATION.
ITEM 3.02.  UNREGISTERED SALES OF EQUITY SECURITIES.

         The Company is amending its Current Report on Form 8-K, filed with the
Securities and Exchange Commission on June 27, 2005 (the "Original Report"), in
which it reported that it entered into a securities purchase agreement
("Purchase Agreement") with a qualified institutional buyer (the "Purchaser") by
which the Purchaser agreed to purchase $75.0 million of the Company's 3.50%
Convertible Senior Subordinated Debentures Due 2012 (the "3.50% Debentures").

         The purpose of the amendment is to report that on June 27, 2005, the
Company completed the sale of the 3.50% Debentures to Highbridge International
LLC, the Purchaser under the Purchase Agreement. Net proceeds of the offering,
together with the Company's existing cash, were used to repay the Company's
$95.0 million 1.250% Convertible Senior Subordinated Debentures due 2024 (the
"1.250% Debentures"). Except for its ownership of a portion of our 1.250%
Debentures, Highbridge International LLC had no material relationship with
the Company.

following agreements:

ITEM 8.01.  OTHER EVENTS

         As noted above, the Disclosure Schedule to the Purchase Agreement is
