TABLE OF CONTENTS

Item 1.01 Entry Into a Material Definitive Agreement.

On March 28, 2006, with the prior approval of its board of directors, Registrant accelerated the vesting of all currently unvested options Registrant had granted to employees and consultants, including officers and directors, which had exercise prices greater than $6.95, the closing price of Registrant’s stock on March 28, 2006. As a condition to these unvested options becoming immediately exercisable, resale restrictions were imposed to prevent the sale of any shares received from the exercise of an accelerated option prior to the original vesting date of the option.

The primary purpose of the accelerated vesting is to enable Registrant to avoid recognizing in its income statement non-cash compensation expense associated with these options in future periods, which amounts to potential savings of approximately $900,000. Registrant would otherwise expect to record these expenses due to the adoption of Financial Accounting Standards Board Statement of Financial Accounting Standards No. 123 (Revised 2004), Share-Based Payment beginning in the first quarter of fiscal 2007. This estimate is subject to change but is based on estimated value calculations using the Black-Scholes methodology.

The acceleration affects options covering approximately 225,000 shares with exercise prices between $7.00 and $22.50 per share, which is about 12% of Registrant’s outstanding unvested options. Of these options, 6,562 are held by David Sear, one of Registrant’s outside directors, comprising approximately 29% of his outstanding unvested options and approximately 7% of the unvested options held by all of Registrant’s outside directors, and 125,000 are held by David Casey, Registrant’s Vice President of Sales, comprising all of his options and approximately 15% of the unvested options held by all of Registrant’s executive officers.
