Attendance of a director at a meeting constitutes a waiver of notice of said meeting, except where the director attends the meeting for the express purpose of objecting to the transaction of any business because the meeting is not lawfully called or convened.

Participation in a meeting pursuant to this Section 3.5 constitutes presence in person at the meeting. SECTION 3.6 Action Without Meeting. Any action required or permitted to be taken at any meeting of the Board of Directors, or of any committee of the Board, may be taken without a meeting if a written consent thereto is signed by all members of the Board or of such committee, as the case may be, and such written consent is filed with the minutes of proceedings of the Board or committee. Such consent shall have the same effect as a vote of the Board or committee for all purposes. SECTION 3.7 Salary and Expenses. Directors shall not receive any stated salary for their services as such. Members of the Board of Directors shall be allowed their reasonable travelling expenses when actually engaged in the business of the corporation. Members of any 9 committee may be allowed like expenses for attending committee meetings.

ARTICLE VI INDEMNIFICATION OF DIRECTORS, OFFICERS, AGENTS AND OTHERS PERSONS SECTION 6.1 Right to Indemnification. Each person who was or is a party or is threatened to be made a party to or is involved (as a party, witness, or other- 15 wise), in any threatened, pending, or completed action, suit, or proceeding, whether civil, criminal, administrative, or investigative (hereafter a "Proceeding"), by reason of the fact that he, or a person of whom he is the legal representative, is or was a director, officer, employee, or agent of the corporation or is or was serving at the request of the corporation as a director, officer, employee, or agent of another foreign or domestic corporation, partnership, joint venture, trust, or other enterprise, or was a director, officer, employee, or agent of a foreign or domestic corporation that was a predecessor corporation of the corporation or of another enterprise at the request of such predecessor corporation, including service with respect to employee benefit plans, whether the basis of the Proceeding is alleged action in an official capacity as a director, officer, employee, or agent or in any other capacity while serving as a director, officer, employee, or agent (hereafter an "Agent"), shall be indemnified and held harmless by the corporation to the fullest extent authorized by statutory and decisional law, as the same exists or may hereafter be interpreted or amended (but, in the case of any such amendment or interpretation, only to the extent that such amendment or interpretation permits the corporation to 16 provide broader indemnification rights than were permitted prior thereto) against all expenses, liability, and loss (including attorneys' fees, judgments, fines, ERISA excise taxes and penalties, amounts paid or to be paid in settlement, any interest, assessments, or other charges imposed thereon, and any federal, state, local, or foreign taxes imposed on any Agent as a result of the actual or deemed receipt of any payments under this Article reasonably incurred or suffered by such person in connection with investigating, defending, being a witness in, or participating in (including on appeal), or preparing for any of the foregoing in any Proceeding (hereafter "Expenses"). The right to indemnification conferred in this Article shall be a contract right. It is the corporation's intention that these bylaws provide indemnification in excess of that expressly permitted by Section 317 of the California General Corporation Law, as authorized by the corporation's Articles of Incorporation. SECTION 6.2 Authority to Advance Expenses. Expenses incurred by an officer or director (acting in his capacity as such) in defending a Proceeding shall be paid by the corporation in advance of the final disposition of such Proceeding, provided, however, that if required by the California General Corporation Law, as 17 amended, such expenses shall be advanced only upon delivery to the corporation of an undertaking by or on behalf of such director or officer to repay such amount if it shall ultimately be determined that he is not entitled to be indemnified by the corporation as authorized in this Article or otherwise. Expenses incurred by other Agents of the corporation (or by the directors or officers not acting in their capacity as such, including service with respect to employee benefit plans) may be advanced upon the receipt of a similar undertaking, if required by law, and upon such other terms and conditions as the Board of Directors deems appropriate. Any obligation to reimburse the corporation for Expense advances shall be unsecured and no interest shall be charged thereon. SECTION 6.3 Right of Claimant to Bring Suit. If a claim under Section 6.1 or 6.2 of these bylaws is not paid in full by the corporation within thirty (30) days after a written claim has been received by the corporation, the claimant may at any time thereafter bring suit against the corporation to recover the unpaid amount of the claim and, if successful in whole or in part, the claimant shall be entitled to be paid also the expense (including attorneys' fees) of prosecuting such claim. It shall be a defense to any such action (other than an 18 action brought to enforce a claim for expenses incurred in defending a Proceeding in advance of its final disposition where the required undertaking has been tendered to the corporation) that the claimant has not met the standards of conduct that make it permissible under the California General Corporation Law for the corporation to indemnify the claimant for the amount claimed. The burden of proving such a defense shall be on the corporation. SECTION 6.4 Provisions Nonexclusive. The rights conferred on any person by this Article shall not be exclusive of any other rights that such person may have or hereafter acquire under any statute, provision of the Articles of Incorporation, agreement, vote of stockholders or disinterested directors, or otherwise, both as to action in an official capacity and as to action in another capacity while holding such office. To the extent that any provision of the Articles, agreement, or vote of the stockholders or disinterested directors is inconsistent with these bylaws, the provision, agreement, or vote shall take precedence. 19 SECTION 6.5 Authority to Insure. The corporation may purchase and maintain insurance to protect itself and any Agent against any Expense asserted against or incurred by such person, whether or not the corporation would have the power to indemmify the Agent against such Expense under applicable law or the provisions of this Article, provided that, in cases where the corporation owns all or a portion of the shares of the company issuing the insurance policy, the company and/or the policy must meet one of the two sets of conditions set forth in Section 317 of the California General Corporation Law, as amended. SECTION 6.6 Survival of Rights. The rights provided by this Article shall continue as to a person who has ceased to be an Agent and shall inure to the benefit of the heirs, executors, and administrators of such person. SECTION 6.7 Settlement of Claims. The corporation shall not be liable to indemnify any Agent under this Article (a) for any amounts paid in settlement of any action or claim effected without the corporation's written consent, which consent shall not be unreasonably withheld; or (b) for any judicial award, if the corporation was not given a reasonable and timely opportunity, 20 at its expense, to participate in the defense of such action. SECTION 6.8 Effect of Amendment. Any amendment, repeal, or modification of this Article shall not adversely affect any right or protection of any Agent existing at the time of such amendment, repeal, or modification. SECTION 6.9 Subrogation. In the event of payment under this Article, the corporation shall be subrogated to the extent of such payment to all of the rights of recovery of the Agent, who shall execute all papers required and shall do everything that may be necessary to secure such rights, including the execution of such documents necessary to enable the corporation effectively to bring suit to enforce such rights. SECTION 6.10 No Duplication of Payments. The corporation shall not be liable under this Article to make any payment in connection with any claim made against the Agent to the extent the Agent has otherwise actually received payment (under any insurance policy, agreement, vote, or otherwise) of the amounts otherwise indemnifiable hereunder. 21 ARTICLE VII CERTIFICATES OF STOCK AND THEIR TRANSFER SECTION 7.1 Certificates of Stock. Every stockholder shall be entitled to a certificate, in such form as the Board of Directors shall from time to time approve, signed by the President or a Vice President and by the Secretary or an Assistant Secretary. Any or all of the signatures on the certificate may be facsimile. In case any officer, transfer agent or registrar who has signed or whose facsimile signature has been placed upon a certificate shall have ceased to be such officer, transfer agent or registrar before such certificate is issued, it may be issued by the corporation with the same effect as if he were such officer, transfer agent or registrar as of the date of such issue. SECTION 7.2 Replacement of Lost or Destroyed Certificates. The Board of Directors may direct a new certificate or certificates to be issued in place of any certificate or certificates theretofore issued by the corporation alleged to have been lost or destroyed, upon the making of an affidavit by the person claiming the certificate to be lost, stolen, or destroyed as to his ownership of the certificate and of the facts as to its loss, theft, or destruction. 22 SECTION 7.3 Transfer of Stock. Upon surrender to the corporation or the transfer agent of the corporation of a certificate for shares duly endorsed or accompanied by proper evidence of succession, assignment, or authority to transfer, it shall be the duty of the corporation to issue a new certificate to the person entitled thereto, cancel the old certificate and record the transaction upon its books. SECTION 7.4 Fixing Record Date. In order that the corporation may determine the stockholders entitled to notice of or to vote at any meeting of stockholders or any adjournment thereof or to express consent to corporate action in writing without a meeting, or entitled to receive payment of any dividend or other distribution or allotment of any rights, or entitled to exercise any rights in respect of any change, conversion or exchange of stock or for the purpose of any other lawful action, the Board of Directors may fix, in advance, a record date, which shall not be more than sixty nor less than ten days before the date of such meeting nor more than sixty days prior to any other action. A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting; provided, however, that the Board of 23 Directors may fix a new record date for the adjourned meeting. SECTION 7.5 Record Ownership of Stock. The corporation shall be entitled to treat the person in whose name any share of stock is registered as the owner thereof, for all purposes, and shall not be bound to recognize any equitable or other claim to, or interest in, such share on the part of any other person, whether or not it shall have notice thereof, except as otherwise expressly provided by the laws of California.

SECTION 8.7 Amendment of Bylaws. These bylaws may be altered, amended or repealed at any meeting of the Board of Directors at which a quorum is present by a majority vote of the directors.
