dealings with Celox, a British customer. The complaint further alleged that the action should be maintained as a plaintiff class action suit on behalf of people who purchased shares of our common stock from April 5, 2001 through October&nbsp;24,
2001. The complaint sought relief including unquatified compensatory damages, attorneys&#146; and expert witness&#146; fees. In March 2002, the plaintiff filed an amended complaint, alleging that we and four of our officers (Joseph Cross, Daniel
Bilicki &#150; our vice president of sales and marketing, Jess Jankowski &#150; our acting chief financial officer, and Gina Kritchevsky &#150; our then-current chief technology officer) are liable under the federal Securities Exchange Act of 1934
for making supposedly fraudulent material misstatements and omissions of fact in connection with our press releases, publicly-filed reports and other public disclosures concerning our relationship with Celox and our purportedly improper booking, and
later reversal, of $400,000 in revenue from a one-time sale to that customer treated as a bill and hold transaction. The amended complaint alleges the same putative class and seeks the same relief as in plaintiff&#146;s initial complaint. The
defendants moved to dismiss the amended complaint in April 2002. In October 2002, the court denied defendants&#146; motion, finding that plaintiff&#146;s 40-page amended complaint asserted sufficient allegations to permit the case to proceed. In
November 2002, defendants answered the amended complaint, denying all wrongdoing. Thereafter, the parties began discovery which currently continues. The plaintiff&#146;s motion for class certification has been fully briefed. However, the court has
not yet ruled on that motion nor has the court indicated when it anticipates ruling. Although we believe that the allegations of the amended complaint are without merit, it is not feasible to predict at this time the ultimate outcome of this
litigation or whether its resolution could have a material adverse effect on our results of operations or financial condition. </FONT></P> <P STYLE="margin-top:0px;margin-bottom:0px"><FONT SIZE="1">&nbsp;</FONT></P><P

opposed to) the best interests of the corporation and, in the case of a criminal action, such person must have had no reasonable cause to believe his or her conduct was unlawful. In addition, the DGCL does not permit indemnification in an action or

deems proper in light of liability adjudication. Indemnity is mandatory to the extent a claim, issue or matter has been successfully defended. </FONT></P><P STYLE="margin-top:0px;margin-bottom:0px"><FONT SIZE="1">&nbsp;</FONT></P><P
