ITEM 1.01    ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

On December 16, 2004 the Company's Board of Directors adopted certain general
changes to the Company's non-executive director and executive compensation plans
to ensure compliance with the deferred compensation provisions of the American
Jobs Creation Act of 2004 which go into effect in 2005. Additional amendments to
the compensation plans will likely be necessary once more specific guidance is
available from the U.S. Internal Revenue Service.
