   The second paragraph of Item 5(a) is hereby amended and restated to read as
follows:

     As of the close of  business  on  September  13,  2004,  Steel  Partners II
beneficially owned 548,319 Shares, constituting approximately 4.8% of the Shares
outstanding.  As the general  partner of Steel Partners II,  Partners LLC may be
deemed to  beneficially  own the  548,319  Shares  owned by Steel  Partners  II,

investment  fund which was  previously  managed on a  discretionary  basis by an
entity previously known as Steel Partners Services,  Ltd., an affiliate of Steel
Partners II, pursuant to an investment management agreement.

   Item 5(c) is hereby amended to add the following:

     Schedule A annexed hereto lists all  transactions by the Reporting  Persons
in the Issuer's Common Stock since the filing of Amendment No. 9 to the Schedule
