CERTAIN BENEFICIAL OWNERS AND MANAGEMENT
The following table sets forth information with respect to the beneficial ownership of shares of the common stock as of March 1, 2006, for:
The amounts and percentages of common stock beneficially owned are reported on the basis of regulations of the SEC governing the determination of beneficial ownership of securities. Under the rules of the SEC, a person is deemed to be a beneficial owner of a security if that person has or shares voting power, which includes the power to vote or to direct the voting of such security, or investment power, which includes the power to dispose of or to direct the disposition of such security. A person is also deemed to be a beneficial owner of any securities of which that person has a right to acquire beneficial ownership within 60 days. Under these rules, more than one person may be deemed a beneficial owner of the same securities, and a person may be deemed a beneficial owner of securities as to which he has no economic interest. The number of shares of common stock outstanding used in calculating the percentage for each listed person includes the shares of common stock underlying options held by such person that are exercisable within 60 days of March 1, 2006, but excludes shares of common stock underlying options held by any other person.
Except in cases where community property laws apply or as indicated by footnote, the persons named in the table below have sole voting and investment power with respect to all shares of common stock shown as beneficially owned by them.
The percentage of beneficial ownership is based on 37,541,383 shares of common stock outstanding as of March 1, 2006.
