According to the Company’s FORM 10-Q For the Quarterly Period Ended June 30, 2006, the underwriters for the Company’s initial public offering, Goldman Sachs & Co., Lehman Bros, Hambrecht & Quist LLC, and Wit Soundview Capital Corp, the Company, and certain current and former officers of the Company were named as defendants in federal securities class action lawsuits filed in the United States District Court for the Southern District of New York. The cases allege violations of various securities laws by more than 300 issuers of stock, including the Company, and the underwriters for such issuers, on behalf of a class of plaintiffs who, in the case of the Company, purchased the Company’s common stock between September 21, 1999 and December 6, 2000 in connection with the Company’s initial public offering. Specifically, the complaints allege that the underwriter defendants engaged in a scheme concerning sales of the Company’s and other issuers’ securities in the initial public offering and in the aftermarket. In July 2003, the Company decided to join in a settlement negotiated by representatives of a coalition of issuers named as defendants in this action and their insurers. Although the Company believes that the plaintiffs’ claims have no merit, the Company has decided to accept the settlement proposal to avoid the cost and distraction of continued litigation. Because the settlement will be funded entirely by the Company’s insurers, the Company does not believe that the settlement will have any effect on its financial condition, results of operation, or cash flows. The proposed settlement agreement is subject to final approval by the court.

The complaint alleges violations of Sections 11, 12(a)(2) and 15 of the Securities Act of 1933 and Section 10(b) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder. The complaint further alleges that the Prospectus was materially false and misleading because it failed to disclose, among other things, that: (i) the Underwriter Defendants had solicited and received excessive and undisclosed commissions from certain investors in exchange for which the Underwriter Defendants allocated to those investors material portions of the restricted number of Kana shares issued in connection with the Kana IPO; and (ii) the Underwriter Defendants had entered into agreements with customers whereby they agreed to allocate Kana shares to those customers in the Kana IPO in exchange for which the customers agreed to purchase additional Kana shares in the aftermarket at pre-determined prices.
