(1) On September 19, 2006, the Reporting Person was granted a restricted stock unit covering up to 62,500 shares of the Issuer's Common Stock which are subject to both performance-vesting and service-vesting requirements. Following the completion of the Issuer's audited financial statements for the 2007 fiscal year, the Issuer's Board of Directors determined on August 8, 2007 the level at which the performance goals were attained, and based on that assessment, determined that the number of shares subject to the restricted stock units is 62,500. The Reporting Person will vest in 50% of the restricted stock units upon his completion of two years of service with the Issuer measured from September 19, 2006 and will vest in the remaining 50% upon his completion of an additional two years of service thereafter. The shares of common stock will be issued as the restricted stock units vest.
(2) Includes 133 shares acquired under the Employee Stock Purchase Plan ("ESPP") on February 1, 2007 and 466 shares acquired under the ESPP on June 29, 2007.
