Pursuant to Rule 416(a) of the Securities Act of 1933, this registration statement shall also
cover any additional shares of the Registrant's Common Stock that become issuable under the
2007 Equity Incentive Plan and the Employee Stock Purchase Plan by reason of any stock
dividend, stock split, recapitalization or other similar transaction effected without receipt
of consideration that increases the number of the Registrant's outstanding shares of Common
Stock.
(2)
For the sole purpose of calculating the registration fee, the number of shares to be
registered under this registration statement has been broken down into two subtotals.
(3)
This amount represents the registration of an aggregate of 3,356,892 additional shares
reserved for issuance under the 2007 Equity Incentive Plan, and 317,548 shares authorized but
not issued under the Registrant's 2003 Share Option and Incentive Plan, which became issuable
under the 2007 Equity Incentive Plan pursuant to its terms.
(4)
This amount represents the registration of additional shares issuable under the Employee
Stock Purchase Plan as of the date of this Registration Statement.
(5)
Offering prices of awards that have not yet been granted as of the date of this registration
statement are computed in accordance with Rule 457(c) and 457(h) of the Securities Act of
1933, as amended, solely for the purpose of calculating the registration fee based upon the
price of $2.83 per share, the average of the high and low prices of the Common Stock of the
Registrant on August 10, 2010 on the Nasdaq Global Market.
(6)
The computation is based upon 85% of the average of the high and low price per share of the
Common Stock as reported on the Nasdaq Global Market on August 10, 2010, which is 85% of
$2.83. Pursuant to the Employee Stock Purchase Plan, the Purchase Price of a share of Common
Stock shall be equal to 85% of the Fair Market Value of a share of Common Stock on the
Exercise Date.
