The following constitutes Amendment No. 23 to the Schedule 13D filed by the undersigned (“Amendment No. 23”).  This Amendment No. 23 amends the Schedule 13D as specifically set forth herein.

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 6,402,029 Shares owned directly by Steel Partners II is approximately $4,505,649, 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 132,250 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 50,000 Shares, which were issued to him in his capacity as President and Chief Executive Officer and a director of the Issuer.

Set forth on Schedule B annexed to Amendment No. 22 to the Schedule 13D (“Schedule B”) is the aggregate purchase price of the Shares beneficially owned, if any, by each of the directors of Steel Holdings GP.

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.

Item 5. Interest in Securities of the Issuer.

Item 5(a) is hereby amended and restated to read as follows:

(a)           The aggregate percentage of Shares reported owned by each person named herein is based upon 22,718,306 Shares outstanding, which is the total number of Shares outstanding as of  March 2, 2010 as reported in the Issuer’s Form 10-Q filed with the Securities and Exchange Commission on March 15, 2010.

As of the close of business on March 15, 2010, Steel Partners II owned directly 6,402,029 Shares, constituting approximately 28.2% 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 and Warren G. Lichtenstein may be deemed to beneficially own the Shares owned by Steel Partners II.

As of the close of business on March 15, 2010, 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 28.4% of the Shares outstanding.  By virtue of their relationships with Steel Holdings discussed in further detail in Item 2, each of Partners LLC 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 28.4% of the Shares outstanding.
