RECENT DEVELOPMENTS

On November 27, 2002, we raised approximately $3.5 million through a private placement of common stock. A total of 1,346,154 shares of our common stock were sold to a group of institutional and accredited investors led by a significant existing investor at a price of $2.60 per share, pursuant to the terms of a Securities Purchase Agreement and Common Stock Warrant.

The investors were also issued 5-year warrants to purchase an aggregate of 806,400 shares of our common stock exercisable at $3.60 per share. Subject to certain exclusions, the price at which the warrants are exercisable is subject to adjustment if we issue shares of common stock for less than the exercise price of the warrants at the time such additional shares of our common stock are issued. The shares excluded from the price adjustment provision include, among certain others:

• additional shares of our common stock issued in connection with a recapitalization, reorganization, consolidation, merger or sale of the company; and

• additional shares of our common stock issued as stock dividends, subdivisions and combinations of our common stock.

Neither the common stock nor the warrants issued in the financing have been registered for sale under the Securities Act of 1933, as amended, and may not be offered or sold in the United States absent registration under such act or applicable exemption from the registration requirements of such act. The Company did not grant any registration rights in connection with this financing.
