INDEMNIFICATION OF OFFICERS AND DIRECTORS. Under Section 145 of the Delaware General Corporation Law, the Registrant has broad powers to indemnify its directors and officers against liabilities they may incur in such capacities, including liabilities under the Securities Act of 1933, as amended (the "Securities Act"). The Registrant's Bylaws also provide that the Registrant will indemnify its directors and executive officers and may indemnify its other officers, employees and other agents to the fullest extent not prohibited by Delaware law. The Registrant's Certificate of Incorporation provides for the elimination of liability for monetary damages for breach of the directors' fiduciary duty of care to the Registrant and its stockholders. These provisions do not eliminate the directors' duty of care and, in appropriate circumstances, equitable remedies such as injunctive or other forms of non-monetary relief will remain available under Delaware law. In addition, each director will continue to be subject to liability for breach of the director's duty of loyalty to the Registrant, for acts or omissions not in good faith or involving intentional misconduct, for knowing violations of law, for any transaction from which the director derived an improper personal benefit, and for payment of dividends or approval of stock repurchases or redemptions that are unlawful under Delaware law. The provision does not affect a director's responsibilities under any other laws, such as the federal securities laws or state or federal environmental laws. The Registrant has entered into agreements with its directors and executive officers that require the Registrant to indemnify such persons against expenses, judgments, fines, settlements and other amounts actually and reasonably incurred (including expenses of a derivative action) in connection with any proceeding, whether actual or threatened, to which any such person may be made a party by reason of the fact that such person is or was a director or officer of the Registrant or any of its affiliated enterprises, provided such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the Registrant and, with respect to any criminal proceeding, had no reasonable cause to believe his or her conduct was unlawful. The indemnification agreements also set forth certain procedures that will apply in the event of a claim for indemnification thereunder. II-1 3 The Underwriting Agreement filed as Exhibit 1.1 to this Registration Statement provides for indemnification by the Underwriters of the Registrant and its officers and directors for certain liabilities arising under the Securities Act or otherwise. The Registrant intends to purchase a general liability insurance policy which covers certain liabilities of directors and officers of the Registrant arising out of claims based on acts or omissions in their capacity as directors or officers. ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES. Since its inception in February 1995, the Registrant has sold and issued the following unregistered securities: (1) In February 1995, the Registrant sold and issued an aggregate of 7,500,000 shares of Series A Preferred Stock to two accredited investors for cash in the aggregate amount of $2,500,000 and the assignment of certain intellectual property rights. (2) In August 1995, the Registrant sold and issued an aggregate of 2,333,333 shares of Series B Preferred Stock to six accredited investors for cash in the aggregate amount of $3,500,000. (3) In March 1996, the Registrant sold and issued 1,200,000 shares of Common Stock to one accredited investor in exchange for a promissory note in the amount of $180,000. (4) In April 1996, the Registrant sold and issued an aggregate of 9,964,607 shares of Series C Preferred Stock and Warrants to purchase 1,496,182 shares of Common Stock to a group of accredited investors for $22,420,363.74. (5) From March 1995 to December 6, 1996, the Registrant granted incentive stock options and nonstatutory stock options to employees, directors and consultants covering an aggregate of 2,362,803 shares of the Registrant's Common Stock, at a weighted average exercise price of $.36 per share. As of December 6, 1996, the Registrant has sold 112,038 shares of its Common Stock to employees, directors and consultants pursuant to exercise of stock options. (6) In December 1996, the Registrant issued a warrant to purchase 74,000 shares of Common Stock to one accredited investor in connection with an equipment lease financing. The share amounts set forth above do not take into account the one-for-three reverse stock split that will be effected prior to the closing of this offering. The sale and issuance of securities in the transactions described in paragraphs (1), (2), (4) and (6) above were deemed to be exempt from registration under the Securities Act by virtue of Section 4(2) adopted thereunder. The purchasers in each case represented their intention to acquire the securities for investment only and not with a view to distribution thereof. Appropriate legends are affixed to the stock certificates or warrants issued in such transactions. All recipients either received adequate information about the Registrant or had access, through employment or other relationships, to such information. The sale and issuance of securities in the transactions described in paragraph (3) and (5) above were deemed to be exempt from registration under the Securities Act by virtue of Rule 701 promulgated thereunder, in that they were issued either pursuant to written compensatory benefit plans or pursuant to a written contract relating to compensation, as provided by Rule 701.

UNDERTAKINGS. The undersigned Registrant hereby undertakes to provide the Underwriters at the closing specified in the Underwriting Agreement certificates in such denominations and registered in such names as required by the Underwriters to permit prompt delivery to each purchaser. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers, and controlling persons of the Registrant pursuant to the provisions described in Item 14 or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer, or controlling person of the Registrant in the successful defense of any action, suit, or proceeding) is asserted by such director, officer, or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue. The undersigned Registrant hereby undertakes that: (1) for purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus as filed as part of the registration statement in reliance upon Rule 430A and contained in the form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of the registration statement as of the time it was declared effective, and (2) for the purpose of determining any liability under the Securities Act, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and this offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. II-4 6 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the Registrant has caused this Amendment to the Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Palo Alto, County of Santa Clara, State of California, on the twenty-eighth day of January, 1997.
