Ownership



 



This Amendment No. 10 to Schedule 13G/A filed on the date hereof reports the beneficial ownership of the Reporting Persons as of December 31, 2009 pursuant to Rule 13d-2(b) of the Securities Exchange Act of 1934, as amended.  No Reporting Person is a beneficial owner of more than five percent (5%) of the Issuer’s Common Stock.

The approximate percentages of shares of Common Stock reported as beneficially owned by the Reporting Persons are based upon 15,772,969 shares of Common Stock outstanding as of October 26, 2009, as reported in the Issuer’s Quarterly Report on Form 10-Q for the quarterly period ended September 27, 2009 (filed with the SEC on November 3, 2009), plus certain shares issuable upon exercise by the Reporting Persons of options to acquire Common Stock.
