        <footnote id="F1">On May 15, 2008, restrictions lapsed with respect to 2,917 shares of restricted stock held by Ms. Kaminsky.  Pursuant to the terms of her restricted stock award, she elected to have the Company withhold 1,334 of such shares in order to satisfy the resulting tax withholding obligation.  As a result, as of that date Ms. Kaminsky held 21,388 restricted shares of the Company's common stock and 8,978 shares of the Company's common stock.</footnote>
        <footnote id="F2">Ms. Kaminsky's holdings in the Company's securities are held in the Bogen Family Trust.  She continues to hold those securities as her sole and separate property and does not share voting or investment power with respect thereto.</footnote>
