ITEM 8.01. OTHER EVENTS.

In December 2004, Sharlene Abrams and Sharmila Shahani adopted stock trading plans for trading in the Registrant’s stock in accordance with the guidelines specified by the Securities and Exchange Commission’s Rule 10b5-1 under the Securities Exchange Act of 1934. Ms. Abrams and Ms. Shahani are executive officers of the Registrant and will file Forms 4 evidencing sales under the stock trading plans as required under Section 16 of the Securities Exchange Act of 1934. This type of trading plan allows a corporate insider to gradually diversify holdings of company stock while minimizing any market effects of such trades by spreading them out over an extended period of time and eliminating any market concern that such trades were made by a person while in possession of material nonpublic information. Consistent with Rule 10b5-1, the Registrant’s insider trading policy permits personnel to implement Rule 10b5-1 trading plans provided that, among other things, they are not in possession of any material nonpublic information at the time that they adopt such plans.

Pursuant to the stock trading plan adopted by Ms. Abrams, sales of stock under the plan shall occur only when the stock can be sold at a per share price of at least $8.25. As of November 30, 2004, Ms. Abrams beneficially owned approximately 530,946 shares of the Registrant’s common stock and held unvested stock options to purchase approximately an additional 61,669 shares of the Registrant’s common stock. The stock trading plan adopted by Ms. Abrams is intended to achieve a gradual diversification of a portion of her present holdings by enabling the sale of an aggregate of up to 100,000 shares, over a period of approximately six months, ending on June 1, 2005.
