(i) If only one votes, such act binds all;

(ii) If more than one vote, the act of the majority so voting binds all;

(iii) If more than one vote, but the vote is evenly split on any particular matter, each faction may vote the securities in question proportionately.

If the instrument so filed or the registration of the shares shows that any such tenancy is held in unequal interests, a majority or even split for the purpose of this section shall be a majority of even split in interest.

Subject to the following sentence and to the provisions of Section 708 of the California General Corporation Law, every shareholder entitled to vote at any election of directors may cumulate such shareholder’s votes and give one candidate a number of votes equal to the number of directors to be elected multiplied by the number of votes to which the shareholder’s shares are entitled, or distribute the shareholder’s votes on the same principle among as many candidates as the shareholder thinks fit. No shareholder shall be entitled to cumulate votes for any candidate or candidates pursuant to the preceding sentence unless such candidate or candidates’ names have been placed in nomination prior to the voting and the shareholder has given notice, at the meeting prior to the voting of the shareholder’s intention to cumulate the shareholder’s votes.

(d) Any inspection and copying under this Article may be made in person or by agent or attorney.

Section 2. Inspection of Bylaws.

The corporation shall keep in its principal executive office the original or a copy of these Bylaws as amended to date which shall be open to inspection by shareholders at all reasonable times during office hours. If the principal executive office of the corporation is outside the state of California and the corporation has no principal business office in such state, it shall upon the written notice of any shareholder furnish to such a shareholder a copy of these Bylaws as amended to date.

Section 3. Endorsement of Documents; Contracts.

Subject to the provisions of applicable law, any note, mortgage, evidence of indebtedness, contract, share certificate, conveyance or other instrument in writing and any assignment or endorsements thereof executed or entered into between this corporation and any other person, when signed by the Chairman of the Board, the President or any Vice President, and the Secretary, any Assistant Secretary, the Chief Financial Officer or any Assistant Financial Officer of this corporation shall be valid and binding on this corporation in the absence of actual knowledge on the part of the other person that the signing officers had no authority to execute the same. Any such instruments may be signed by any other person or persons and in such manner as from time to time shall be determined by the Board, and unless so authorized by the Board, no officer, agent or employee shall have any power or authority to bind the corporation by any contract or engagement or to pledge its credit or to render it liable for any purpose or amount.

Section 4. Certificates of Stock.

Any or all of the signatures on the certificate may be facsimile. If 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 an officer, transfer agent or registrar before such certificate is issued, it may be issued by the corporation with the same effect as if such person were an officer, transfer agent or registrar at the date of issue.

–18–

Certificates for shares may be issued prior to full payment under such restrictions and for such purposes as the Board may provide; provided, however, that on any certificate issued to represent any partly paid shares, the total amount of the consideration to be paid therefor and the amount paid thereon shall be stated.

Except as provided in this Section, no new certificate for shares shall be issued in lieu of an old one unless the latter is surrendered and cancelled at the same time. The Board may, however, in case any certificate for shares is alleged to have been lost, stolen or destroyed, authorize the issuance of a new certificate in lieu thereof, and the corporation may require that the corporation be given a bond or other adequate security sufficient to indemnify it against any claim that may be made against it (including expense or liability) on account of the alleged loss, theft or destruction of such certificate or the issuance of such new certificate.

Section 5. Representation of Shares of Other Corporations.

The President or any other officer or officers authorized by the Board or the President are each authorized to vote, represent and exercise on behalf of the corporation all rights incident to any and all shares of any other corporation or corporations standing in the name of the corporation. The authority herein granted may be exercised either by any such officer in person or by any other person authorized so to do by proxy or power of attorney duly executed by said officer.

Section 6. Stock Purchase Plans.

The corporation may adopt and carry out a stock purchase plan or agreement or stock option plan or agreement providing for the issue and sale for such consideration as may be fixed of its unissued shares, or of issued shares acquired or to be acquired, to one or more of the employees or directors of the corporation or of a subsidiary or to a trustee on their behalf and for the payment for such shares in installments or at one time and may provide for aiding any such persons in paying for such shares by compensation for services rendered, promissory notes, or otherwise.

Any such stock purchase plan or agreement or stock option plan or agreement may include, among other features, the fixing of eligibility for participation therein, the class and price of shares to be issued or sold under the plan or agreement, the number of shares which may

–19–

be subscribed for, the method of payment therefor, the reservation of title until full payment therefor, the effect of the termination of employment and option or obligation on the part of the corporation to repurchase the shares, the time limits of and termination of the plan and any other matters not in violation of applicable law, as may be included in the plan as approved or authorized by the Board or any committee of the Board.

Section 7. Annual Report to Shareholders.

The annual report to shareholders referred to in Section 1501 of the California General Corporation Law is expressly waived, but nothing herein shall be interpreted as prohibiting the Board from issuing annual or other periodic reports to shareholders.

Section 8. Construction and Definitions.

Unless the context otherwise requires, the general provisions, rules of construction and definitions contained in the General Provisions of the California Corporations Code and in the California General Corporation Law shall govern the construction of these Bylaws.

ARTICLE VI.

INDEMNIFICATION

Section 1. Definitions.

For the purposes of this Article, “agent” includes any person who is or was a director, officer, employee or other 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 which was a predecessor corporation of the corporation of another enterprise at the request of such predecessor corporation; “proceeding” includes any threatened, pending or completed action or proceeding, whether civil, criminal, administrative or investigative; and “expenses” includes attorneys’ fees and any expenses of establishing a right to indemnification under Section 4 of Section 5(c).

Section 2. Indemnification in Actions by Third Parties.

The corporation shall have power to indemnify any person who was or is a party or is threatened to be made a party to any proceeding (other than an action by or in the right of the corporation) by reason of the fact that such person is or was an agent of the corporation, against expenses, judgments, fines, settlements and other amounts

–20–

actually and reasonably incurred in connection with such proceeding if such person acted in good faith and in a manner such person reasonably believed to be in the best interests of the corporation and, in the case of a criminal proceeding, had no reasonable cause to believe the conduct of such person was unlawful. The termination of any proceeding by judgment, order, settlement, conviction or upon a plea of nolo contendere or its equivalent shall not, of itself, create a presumption that the person did not act in good faith and in a manner which the person reasonably believed to be in the best interests of the corporation or that the person had reasonable cause to believe that the person’s conduct was unlawful.

Section 3. Indemnification in Actions by or in the Right of the Corporation.

The corporation shall have power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action by or in the right of the corporation to procure a judgment in its favor by reason of the fact such person is or was an agent of the corporation, against expenses actually and reasonably incurred by such person in connection with the defense or settlement of such action if such person acted in good faith, in a manner such person believed to be in the best interests of the corporation, and with such care, including reasonable inquiry, as an ordinarily prudent person in a like position would use under similar circumstances. No indemnification shall be made under this Section 3:

(a) In respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation in the performance of such person’s duty to the corporation, unless and only to the extent that the court in which such action was brought shall determine upon application that, in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for the expenses which such court shall determine;

(b) Of amounts paid in settling or otherwise disposing of a threatened or pending action, with or without court approval; or

(c) Of expenses incurred in defending a threatened or pending action which is settled or otherwise disposed of without court approval.

–21–

Section 4. Indemnification Against Expenses.

To the extent that an agent of the corporation has been successful on the merits in defense of any proceeding referred to in sections 2 or 3 or in defense of any claim, issue or matter therein, the agent shall be indemnified against expenses actually and reasonably incurred by the agent in connection therewith.

Section 5. Required Determination.

Except as provided in Section 4, any indemnification under this Article shall be made by the corporation only if authorized in the specific case, upon a determination that indemnification of the agent is proper is in the circumstances because the agent has met the applicable standard of conduct set forth in Sections 2 or 3 by:

(a) A majority vote of a quorum consisting of directors who are not parties to such proceeding;

(b) Approval of the shareholders, with the shares owned by the person to be indemnified not being entitled to vote thereon; or

(c) The court in which such proceeding is or was pending upon application made by the corporation or the agent or the attorney or other person rendering services in connection with the defense, whether or not such application by the agent, attorney or other person is opposed by the corporation.

Section 6. Advance of Expenses.

Expenses incurred in defending any proceeding may be advanced by the corporation prior to the final disposition of such proceeding upon receipt of an undertaking by or on behalf of the agent to repay such amount unless it shall be determined ultimately that the agent is entitled to be indemnified as authorized in this Article.

Section 7. Other Indemnification.

No provision made by the corporation to indemnify its or its subsidiary’s directors or officers for the defense of any proceeding, whether contained in the Articles, Bylaws, a resolution of shareholders or directors, an agreement, or otherwise, shall be valid unless consistent with this Article. Nothing contained in this Article shall affect any right to indemnification to which persons other than such directors and officers may be entitled by contract or otherwise.

–22–

Section 8. Forms of Indemnification Not Permitted.

No indemnification or advance shall be made under this Article, except as provided in Section 4 or Section 5(c) in any circumstance where it appears:

(a) That it would be inconsistent with a provision of the Articles, Bylaws, a resolution of the shareholders or an agreement in effect at the time of the accrual of the alleges cause of action asserted in the proceeding in which the alleged expenses were incurred or other amounts were paid, which prohibits or otherwise limits indemnification; or

(b) That it would be inconsistent with any condition expressly imposed by a court in approving a settlement.

Section 9. Insurance.

The corporation shall have power to purchase and maintain insurance on behalf of any agent or the corporation against any liability asserted against or incurred by the agent in such capacity or arising out of the agent’s status as such whether or not the corporation would have the power to indemnify the agent against such liability under the provisions of this Article.

Section 10. Nonapplicability to Fiduciaries of Employee Benefit Plans.

This Article does not apply to any proceeding against any trustee, investment manager or other fiduciary of an employee benefit plan in such person’s capacity as such even though such person may also be an agent of the corporation as defined in Section 1. Nothing contained in this Article shall limit any right to indemnification to which such a trustee, investment manager or other fiduciary may be entitled by contract or otherwise which shall be enforceable to the extent permitted by applicable law other than Section 317 of the California General Corporation Law.

ARTICLE VIII.

AMENDMENTS

These Bylaws may be amended or repealed either by approval of the outstanding shares or by the approval of the Board; provided, however, that after the issuance of shares, a Bylaw specifying or changing a fixed number of directors or the maximum or minimum number or changing from a fixed to a variable Board or vice versa may only be adopted by approval of the outstanding shares.
