ITEM 1.01  ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

         On January 31, 2006, we executed an agreement with an institutional
lender to which such lender provided us with a commitment for a $160 million
senior secured credit facility to be used to refinance all of our existing
indebtedness (except for $16.1 million of outstanding subordinated debentures
and $6.1 million of capital lease obligations). The commitment provides for a
$15 million five year revolving credit facility, an $85 million term loan due in
five years and a $60 million second lien term loan due in six years. The loans
are subject to acceleration on February 28, 2008, unless we have made
arrangements to discharge or extend our outstanding subordinated debentures by
that date. The loans are essentially payable interest only monthly at varying
rates yet to be finalized to be based upon market conditions.

         Finalization of the credit facility is subject to customary conditions,
including legal due diligence and final documentation which is scheduled for
completion on or about March 7, 2006.
