DESCRIPTION OF SECURITIES Not applicable. ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL Not applicable. ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS Section 145 of the General Corporation Law of Delaware, the Company's state of incorporation, allows Delaware companies to provide certain indemnification rights for the benefit of their officers, directors, employees and agents. The Company's Restated Certificate of Incorporation ("Certificate") and Amended and Restated Bylaws ("Bylaws") contain indemnification provisions covering directors, employees and agents of the Company. The Certificate requires the Company to indemnify a person covered by the indemnification provisions ("Indemnitee") to the fullest extent permitted by applicable law. The indemnification is for expenses, liabilities and losses (including, but not limited to, attorney's fees, judgments, amounts paid in settlements, fines and penalties) (collectively, the "Expenses") reasonably incurred by an Indemnitee named or involved in a threatened, pending or completed proceeding whether civil, administrative or criminal in nature. An Indemnitee is not entitled to indemnification in the following circumstances. The first is when a proceeding is initiated by him/her without the Company's prior approval. The second is when an Indemnitee's conduct (which is the subject of the proceeding) does not meet the standard of conduct (see below) called for under the Delaware indemnification statutes. Additionally, if an Indemnitee is found liable for negligence or misconduct in the performance of his/her duty to the Company in the proceeding for which indemnification is sought, he/she may be indemnified but only if the court in which the proceeding was brought finds that the Indemnitee is entitled to indemnification of expenses (and at an amount) which the court deems appropriate. A majority of the Board of Directors of the Company who are not a party to the proceeding, the Company's legal counsel, if requested by the Board, or the Company's stockholders may determine whether or not an Indemnitee has met the necessary standard of conduct. An Indemnitee's standard of conduct called for by the Delaware statute on civil disputes requires that he/she acted in good faith and in a manner he/she reasonably believed to be in, or not opposed to, the best interests of the Company. The applicable standard on criminal matters requires that the Indemnitee have no reasonable cause to believe that his/her conduct was unlawful. The Company will reimburse Expenses incurred by an Indemnitee who is an officer or director of the Company in defending a proceeding even if it has not been finally resolved but only if the officer/director promises in writing to reimburse the Company for amounts advanced in case it is determined that the officer/director was not entitled to be indemnified by the Company. In case an indemnity claim is not paid within 30 days of written payment demand, the Company may be liable for the Indemnitee's costs of enforcing his indemnity rights. The indemnification provisions in the Certificate and Bylaws are not intended to and do not supersede, diminish or replace any other indemnity rights that an Indemnitee may presently have or acquire in the future due to, but not limited to, statutory changes, contract(s) entered into, action by the stockholders or the Board of Directors. Moreover, any repeal or modification of the current indemnification provisions in the Certificate or Bylaws will not diminish any indemnification rights that an Indemnitee may have had with respect to proceedings that arose before the repeal or modification of the indemnification provisions. In case some of the indemnification provisions in the Certificate or Bylaws are legally invalidated, the Company will continue to be obligated to indemnify an Indemnitee for Expenses for which indemnification is available under the indemnification provisions that were not legally invalidated and to the full extent permitted by applicable law. The Company's Certificate eliminates personal liability of directors to the Company or its stockholders for monetary damages for breach of fiduciary duty as a director, except for: (i) any breach of the duty of loyalty to the Company or its stockholders; (ii) acts or omissions not in good faith or that involve intentional misconduct or knowing violations of law; (iii) liability under Section 174 of the Delaware General Corporation Law relating to certain unlawful dividends and stock repurchases; or (iv) any transaction from which the director derived an improper personal benefit. The Company has entered into individual indemnification agreements with its directors, executive officers and certain other officers. The indemnification agreements provide for indemnification to the fullest extent permitted by law and provide contractual assurance to directors and officers that indemnity and advancement of expenses will be available to them regardless of any amendment or revocation of the Company's Bylaws. The Bylaws permit the Company to purchase and maintain insurance on behalf of any director, officer, employee or agent of the Company against liability asserted against him or her in any such capacity, whether or not the Company would have the power to indemnify him or her against such liability under the provisions of the Bylaws. ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED Not applicable. ITEM 8. EXHIBITS See the attached Exhibit Index at page 9, which is incorporated herein by reference. ITEM 9. UNDERTAKINGS (a) The undersigned Registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement: (i) To include any prospectus required by Section 10(a)(3) of the Securities Act; (ii) To reflect in the prospectus any facts or events arising after the effective date of this Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this Registration Statement; and (iii) To include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or any material change to such information in this Registration Statement; provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or 15(d) of the Exchange Act that are incorporated by reference in this Registration Statement. (2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (b) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant's annual report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in this Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (h) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, executive officers and controlling persons of the Registrant pursuant to the provisions described in Item 6 above, or otherwise, the Registrant has been advised that in the opinion of the 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. SIGNATURES Pursuant to the requirements of the Securities Act, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this Form S-8 Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Camarillo, State of California, on December 20, 2005.
