Item 1.01.                                          Entry into a Material Definitive Agreement.
 

On September 6, 2005, the Company’s Board of Directors approved accelerating the vesting of certain unvested stock options awarded under the Company’s stock option plans, other than its 2003 Outside Director Stock Option Plan.  The Board of Directors approved the accelerated vesting of stock options held by employees, including executive officers, that were both unvested and “out-of-the-money” (with exercise prices greater than $16.95, the closing sales price of the Company’s common stock on the Nasdaq National Market on September 6, 2005).  As a result of this vesting acceleration, options to purchase approximately 1.6 million shares of the Company’s common stock have become fully vested.

 

The primary purpose of the accelerated vesting was to eliminate the accounting charge in connection with future compensation expense the Company would otherwise recognize in its statement of operations with respect to these accelerated options upon the adoption of Financial Accounting Standards Board Statement of Financial Accounting Standards No. 123 (Revised 2004), Share-Based Payment (FAS 123R).  FAS 123R will require that compensation expense associated with stock options be recognized in the statement of operations, rather than as a footnote disclosure in the Company’s consolidated financial statements.  FAS 123R will become effective for the Company beginning October 3, 2005.
