Shares
of our Common Stock Issuable as Payment of Interest on Debentures
On March
2, 2009, we formally notified the holders of our outstanding 9% Senior
Convertible Debentures due 2012 (the “Debentures”) that all of the interest
payable under the Debentures on April 1, 2009, and on each interest payment date
thereafter shall be paid in shares of our common stock. Our election to pay
interest under the Debentures in shares of common stock will apply to all future
interest payment dates until a revised notice is sent to the holders of the
Debentures.
