Item 3. Source and Amount of Funds or Other Consideration.

Item 3 is hereby amended and restated to read as follows:

The aggregate purchase price of the 5,252,413 Shares owned directly by Steel Partners II is approximately $3,183,758, including brokerage commissions.  The Shares owned directly by Steel Partners II were acquired with partnership funds.  The aggregate purchase price of the 57,292 Shares owned directly by Steel Holdings is approximately $136,230, including brokerage commissions.  The Shares owned directly by Steel Holdings were acquired with the working capital of a predecessor entity of Steel Holdings.  Mr. Henderson owns options that are exercisable within 60 days of the date hereof to purchase 113,500 Shares, which were issued to him in his capacity as a director of the Issuer.  Mr. Quicke owns options that are exercisable within 60 days of the date hereof to purchase 25,000 Shares, which were issued to him in his capacity as President and Chief Executive Officer of the Issuer.

Steel Partners II and Steel Holdings effect purchases of securities primarily through margin accounts maintained for them with prime brokers, which may extend margin credit to them as and when required to open or carry positions in the margin accounts, subject to applicable federal margin regulations, stock exchange rules and the prime brokers’ credit policies.  In such instances, the positions held in the margin accounts are pledged as collateral security for the repayment of debit balances in the accounts.

As of the close of business on November 23, 2009, Steel Partners II owned directly 5,252,413 Shares, constituting approximately 21.7% of the Shares outstanding.  By virtue of their relationships with Steel Partners II discussed in further detail in Item 2, each of Steel Holdings, Partners LLC, Steel Partners GP and Warren G. Lichtenstein may be deemed to beneficially own the Shares owned directly by Steel Partners II.

As of the close of business on November 23, 2009, Steel Holdings owned directly 57,292 Shares, which, together with the Shares owned directly by Steel Partners II that Steel Holdings may also be deemed to beneficially own, constitute approximately 21.9% of the Shares outstanding.  By virtue of their relationships with Steel Holdings discussed in further detail in Item 2, each of Partners LLC, Steel Partners GP and Warren G. Lichtenstein may be deemed to beneficially own the Shares owned directly by Steel Holdings, which, together with the Shares owned directly by Steel Partners II that they may also be deemed to beneficially own, constitute approximately 21.9% of the Shares outstanding.
