It shall also state (a) for special meetings, the general nature of the proposed business, or (b) for annual meetings, those matters which the board of directors at the time of giving the notice intends to present for action by the shareholders. If directors are to be elected, the notice shall include the names of all nominees and persons whom the board intends to present for election, as of the date of the notice. The notice shall also state the general nature of any proposed action at the meeting to approve:

(a) A transaction in which a director has a financial interest, within the meaning of Section 310 of the California Corporations Code;

-2-

(e) A distribution in dissolution that requires approval of the outstanding shares under Section 2007 of that Code.

The manner of giving notice and the determination of shareholders entitled to receive notice shall be in accordance with these bylaws.

Section 5. MANNER OF GIVING NOTICE; AFFIDAVIT OF NOTICE. Notice of any shareholders’ meeting shall be given either (a) personally, or (b) by first-class mail or by telegraphic or other written communication, charges prepaid, addressed to the shareholder at the address appearing on the corporation’s books or supplied by the shareholder for purposes of notice. If the corporation has no such address for a shareholder, notice shall be either (a) sent by first-class mail addressed to the shareholder at the corporation’s principal executive office, or (b) published at least once in a newspaper of general circulation in the county where the corporation’s principal executive office is located. Notice is deemed to have been given at the time it was delivered personally, deposited in the mail, or sent by other means of written communication.

If any notice or report mailed to a shareholder at the shareholder’s address (as specified in the preceding paragraph) is returned marked “unable to deliver” at that address, subsequent notices or reports shall be deemed to have been duly given without further mailing if the corporation holds the document available for the shareholder on written demand at its principal executive office for one year from the date on which the notice or report was sent to the other shareholders.

An affidavit, certificate, or declaration of mailing (or other authorized means of delivery) of any notice of shareholders’ meeting, report, or other document sent to shareholders shall be executed by the corporate secretary, assistant secretary, or transfer agent, and filed in the corporation’s minute book.

Section 6. ADJOURNED MEETINGS; NOTICE. Shareholders’ meetings (either annual or special) may be adjourned from time to time by a vote of the majority of the shareholders represented at that meeting in person or by proxy, whether or not a quorum is present; however, in the absence of a quorum, no other business may be transacted, except as specifically authorized in these bylaws.

If a meeting is adjourned to another time or place, new notice is not required if the new time and place were announced at the original meeting, unless (a) the board sets a new record date for this purpose, or (b) the adjournment is for more than 45 days from the original meeting date, in which case the board must

-3-

set a new record date. If a new record date is set, new notice shall be given to the shareholders of record as of that date, in the same manner as other notices of meetings. At an adjourned meeting, the corporation may transact any business that would be proper at the original meeting.

Section 7. WAIVER OF NOTICE OR CONSENT BY ABSENTEES. The transactions of any shareholders’ meeting, either annual or special, however called and noticed and wherever held, shall be as valid as though they were had at a meeting duly held after regular call and notice, if a quorum is present either in person or by proxy, and if each person entitled to vote but not present at the meeting signs a written waiver of notice, a consent to holding the meeting, or an approval of the minutes. Shareholders’ signatures may be obtained either before or after the meeting. The waiver of notice or consent need not specify either the intended business or the purpose of the meeting, except that if action is taken or proposed to be taken regarding any of the matters specified in Section 601(f) of the California Corporations Code (and listed above in the paragraph on contents of notices of shareholder meetings), the general nature of the action or proposed action must be stated in the waiver of notice or consent. All written waivers, consents, and approvals shall be filed with the corporate records or made a part of the minutes of the meeting.

Notice is also waived by a shareholder’s attendance at the meeting, unless the shareholder at the beginning of the meeting objects to the transaction of any business on the ground that the meeting was not lawfully called or convened. Attendance and failure to object to the validity of the meeting, however, does not constitute a waiver of any right to object expressly, at a meeting, to consideration of matters required by law to be included in the notice of the meeting which were not so included.

Section 8. ACTION BY WRITTEN CONSENT WITHOUT A MEETING. Any action that could be taken at an annual or special meeting of shareholders, except for the election of directors (see following paragraph), may be taken without a meeting and without prior notice, if a consent in writing, setting forth the action so taken, is signed by the holders of outstanding shares having at least the minimum numbers of votes necessary to authorize or take that action at a meeting at which all shares entitled to vote on that action were present and voting.

Directors may be elected without a meeting only by the unanimous written consent of all shares entitled to vote for the election of directors, except that vacancies the board is entitled to fill (vacancies other than those caused by removal of a director) may be filled by the written consent of a majority of the outstanding shares entitled to vote.

-4-

All written consents shall be filed with the secretary of the corporation and maintained in the corporate records. Anyone who has given a written consent may revoke it by a writing received by the secretary of the corporation before written consents of the number of shares required to authorize the proposed action have been filed with the secretary.

Unless the consents of all shareholders entitled to vote have been solicited in writing, the secretary shall give prompt notice of any corporate action approved by the shareholders without a meeting by less than unanimous consent, to those shareholders entitled to vote who have not consented in writing. As to approvals required by California Corporations Code Section 310 (transactions in which a director has a financial interest), Section 317 (indemnification of corporate agents). Section 1201 (corporate reorganization), or Section 2007 (certain distributions on dissolution), notice of the approval shall be given at least ten days before the consummation of any action authorized by the approval. Notice shall be given in the manner specified in these bylaws for notice of shareholders’ meetings.

Section 9. RECORD DATE FOR SHAREHOLDER NOTICE AND VOTING. (a) For purposes of determining the shareholders entitled to receive notice of and vote at a shareholders’ meeting or give written consent to corporate action without a meeting, the board may fix in advance a record date that is not more than 60 days nor less than 10 days before the date of any such meeting, or not more than 60 days before any such action without a meeting.

(b) If no record date has been fixed:

(i) The record date for determining shareholders entitled to receive notice of and vote at a shareholders’ meeting shall be the business day next preceding the day on which notice is given, or if notice is waived as provided in these bylaws, the business day next preceding the day on which the meeting is held;

(ii) The record date for determining shareholders entitled to give written consent to corporate action without a meeting shall be the day on which the action to be approved was taken by the board, or, if the board has not yet acted, the day on which the first written consent is given; and

(iii) The record date for any other purpose shall be as set forth in the section of these bylaws regarding record date for purposes other than notice and voting.

(c) A determination of shareholders of record entitled to receive notice of and vote at a shareholders’ meeting shall apply to any adjournment of the meeting unless the board fixes a new record date for the adjourned meeting. However, the board shall fix a new record date if the adjournment is to a date more than 45 days after the date set for the original meeting.

-5-

(d) Except as otherwise required by law, only shareholders of record on the corporation’s books at the close of business on the record date shall be entitled to any of the notice and voting rights listed in subsection (a) of this section, notwithstanding any transfer of shares on the corporation’s books after the record date.

Section 10. QUORUM. The presence in person or by proxy of the holders of a majority of the shares entitled to vote at any meeting of shareholders shall constitute a quorum for the transaction of business. The shareholders present at a duly called or held meeting at which a quorum was initially present may continue to do business until adjournment, notwithstanding the withdrawal of enough shareholders to leave less than a quorum; however, any action taken (other than adjournment) must be approved by at least a majority of the shares requires to constitute a quorum.

Section 11. VOTING. The corporation shall determine the shareholders entitled to vote at any shareholders’ meeting in accordance with bylaw provisions for record date, subject to Sections 702 through 704 of the California Corporations Code (concerning the voting of shares held by a fiduciary, a corporation, or joint owners). Except as otherwise provided by law or as otherwise provided in the Articles of Incorporation or these bylaws, each outstanding share shall be entitled to one vote on each matter submitted to a vote of the shareholders.

The shareholders may vote by voice vote or by ballot, except that if any shareholder so demands before the voting begins, any election for directors must be by ballot. On any matter other than the election of directors, a shareholder may vote part of his or her shares in favor of the proposal and refrain from voting the remaining shares or vote them against the proposal. If a shareholder does not specify the number of shares being voted, it will be conclusively presumed that the shareholder’s vote covers all shares which that shareholder is entitled to vote.

If a quorum is present (or if a quorum had been present earlier at the meeting but some shareholders have withdrawn), the affirmative vote of a majority of the shares represented and voting, provided such affirmative vote also constitutes a majority of the number of shares required for a quorum, shall be the act of the shareholders unless the vote of a greater number or voting by classes is required by statute or by the Articles of Incorporation.

-6-

Section 12. CUMULATIVE VOTING. Cumulative voting for the election of directors is permitted if one or more shareholders present at the meeting give notice, before the voting begins, of their intention to cumulate votes (i.e., cast for any candidate a number of votes greater than the number of votes which that shareholder would normally be entitled to cast). If any shareholder has given such notice, and if the candidates’ names have been placed in nomination, then all shareholders entitled to vote may cumulate their votes, giving any nominated candidate a number of votes equal to the number of directors to be elected multiplied by the number of votes to which that shareholder’s shares are normally entitled, or distributing the cumulative number of votes among any or all of the candidates. The elected directors shall be those candidates (up to the number of directorships open for election) receiving the most votes.

Section 13. PROXIES. Every person entitled to vote for directors or on any other matter shall have the right to do so either in person or by one or more agents authorized by a written proxy signed by the person and filed with the secretary of the corporation. A proxy shall be deemed signed if the shareholder’s name is placed on the proxy (whether by manual signature, typewriting, telegraphic transmission, or otherwise) by the shareholder or the shareholder’s attorney in fact.

A validly executed proxy that does not state that it is irrevocable shall continue in full force and effect unless (a) it is revoked by the person who executed the proxy, either by a writing delivered to the corporation before the proxy has been voted, or by attendance at the meeting; or (b) the corporation receives written notice of the shareholder’s death or incapacity before the vote pursuant to that proxy has been counted; provided, however, that no proxy shall be valid after the expiration of 11 months from the date of the proxy unless the proxy itself provides otherwise.

Proxies stating on their face that they are irrevocable shall be governed by Sections 705(e) and 705(f) of the California Corporations Code.

Section 14. VOTING TRUSTS. If any shareholders file a voting trust agreement with the corporation, the corporation shall take notice of its terms and trustee limitations.

Section 15. ELECTION INSPECTORS. Before any shareholders’ meeting, the board of directors may appoint any persons other than nominees for office to act as election inspectors. If no election inspectors have been so appointed, the chairman of the meeting may, and on the request of any shareholder or shareholder’s proxy shall, appoint election inspectors at the meeting. The number of inspectors shall be either 1 or 3. If inspectors are appointed at the meeting on the request of one or

-7-

more shareholders or their proxies, the holders of a majority of shares or their proxies present at the meeting shall determine whether 1 or 3 inspectors are to be appointed. If any inspector fails to appear or fails or refuses to act, the chairman of the meeting may, and on the request of any shareholder or shareholder’s proxy shall, appoint a person to fill that vacancy. These inspectors shall (a) determine the number of shares outstanding and the voting power of each, the shares represented at the meeting, the existence of a quorum, and the authenticity, validity, and effect of proxies; (b) receive votes, ballots, or consents; (c) hear and determine all challenges and questions in any way arising in connection with the right to vote; (d) count and tabulate all votes or consents; (e) determine when the polls shall close; (f) determine the result; and (g) do any other acts that may be proper to conduct the election or vote with fairness to all shareholders.

ARTICLE III:DIRECTORS

Section 1. POWERS. Subject to the provisions of the California General Corporation Law and any limitations in the Articles of Incorporation and these bylaws relating to actions requiring approval by the shareholders or by the outstanding shares, the business and affairs of the corporation shall be managed and all corporate powers shall be exercised by or under the direction of the board of directors.

Without prejudice to these general powers, and subject to the same limitations, the board of directors shall have the power to:

This number can be changed by an amendment to the Articles of Incorporation or an amendment to this bylaw adopted by the vote or written consent of a majority of the outstanding shares entitled to vote. However, if the number of directors is five or more, an amendment that would reduce the number of directors to a number less than five cannot be adopted if the votes cast against its adoption at a meeting or the shares not consenting to an action by written consent are equal to more than one sixth (16 ²/3 percent) of the outstanding shares entitled to vote.

Number of Directors: One.

Section 3. ELECTION AND TERM OF DIRECTORS. Directors shall be elected at each annual shareholders’ meeting, to hold office until the next annual meeting.

Each director, including a director elected to fill a vacancy, shall hold office until the expiration of the term for which elected and until a successor has been elected and qualified.

No reduction of the authorized number of directors shall have the effect of removing any director before his or her term of office expires.

Section 4. VACANCIES. A vacancy in the board of directors shall be deemed to exist (a) if a director dies, resigns, or is removed by the shareholders or an appropriate court, as provided in Section 303 or Section 304 of the California Corporations Code; (b) if the board of directors declares vacant the office of a director who has been convicted of a felony or declared of unsound mind by an order of court; (c) if the authorized number of directors is increased; or (d) if at a shareholders’ meeting the shareholders fail to elect the fall authorized number of directors. Vacancies (except for those caused by a director’s removal) may be filled by a majority of the remaining directors, whether or not they constitute a quorum, or by a sole remaining director.

Vacancies on the board caused by the removal of a director (except for vacancies created when the board declares

-9-

the office of a director vacant as provided in clause (b) of the first paragraph of this section) may be filled only by the shareholders, either by majority vote of the shares represented and voting at a meeting at which a quorum is present, or by the unanimous written consent of all shares entitled to vote.

Any director may resign effective on giving written notice to the chairman of the board, the president, the secretary, or the board of directors, unless the notice specifies a later effective date. If the resignation is effective at a future time, the board of directors may elect a successor to take office when the resignation becomes effective.

The shareholders may elect a director at any time to fill a vacancy not filled by the board of directors.

The term of office of a director elected to fill a vacancy shall run until the next annual shareholders’ meeting, and the director shall hold office until a successor is elected and qualified.

Any meeting, regular or special, may be held by conference telephone or similar communication equipment, provided that all directors participating can hear one another, and all such directors shall be deemed to be present at the meeting.

Section 6. ANNUAL DIRECTORS’ MEETING. Immediately after each annual shareholders’ meeting, the board of directors shall hold a regular meeting at the same place or at any other place designated by the board, to elect officers and transact other necessary business as desired. Notice of this meeting shall not be required unless some place other than the place of the annual shareholders’ meeting has been designated.

Section 7. OTHER REGULAR MEETINGS. Other regular meetings of the board of directors shall be held without call at times to be fixed by the board of directors from time to time. Such regular meetings may be held without notice.

-10-

Special meetings shall be held on 4 days’ notice by mail or 48 hours’ notice delivered personally or by telephone or telegraph. Oral notice given personally or by telephone may be transmitted either to the director or to a person at the director’s office who can reasonably be expected to communicate it promptly to the director. Written notice, if used, shall be addressed to each director at his or her address shown on the corporate records. The notice need not specify the purpose of the meeting, nor need it specify the place if the meeting is to be held at the principal executive office of the corporation.

Section 9. WAIVER OF NOTICE. Notice of a meeting, if otherwise required, need not be given to any director who (a) either before or after the meeting signs a waiver of notice or a consent to holding the meeting without being given notice, (b) signs an approval of the minutes of the meeting, or (c) attends the meeting without protesting the lack of notice before or at the beginning of the meeting. Waivers of notice or consents need not specify the purpose of the meeting.

Section 10. QUORUM. A majority of the authorized number of directors shall constitute a quorum for the transaction of business, except for adjournment.

Except as otherwise required by California Corporations Code Section 310 (approval of contracts or transactions in which a director has a material financial interest), Section 311 (appointment of committees), and Section 317(e) (indemnification of directors), every act done or decision made by a majority of the directors present at a meeting duly held at which a quorum is present shall be deemed the act of the board of directors, unless a different requirement is imposed by the Articles of Incorporation.

A meeting at which a quorum was initially present may continue to transact business despite the withdrawal of directors, if the action taken is approved by at least a majority of the quorum required for that meeting.

Section 11. ADJOURNMENT TO ANOTHER TIME OR PLACE. Whether or not a quorum is present, a majority of the directors present may adjourn any meeting to another time and place.

Section 12. NOTICE OF ADJOURNED MEETING. Notice of the time and place of resuming an adjourned meeting need not be given if the adjournment is for 24 hours or less. If the adjournment is for more than 24 hours, notice of the new time and place shall be given, before the time set for resuming the meeting, to any directors who were not present at the time of adjournment, but need not be given to directors who were present at the time of adjournment.

-11-

Section 13. ACTION WITHOUT A MEETING BY WRITTEN CONSENT. Any action required or permitted to be taken by the board of directors may be taken without a meeting, if all members of the board individually or collectively consent in writing to that action. Any action by written consent shall have the same effect as a unanimous vote of the board of directors. All such written consents shall be filed with the minutes of the proceedings of the board of directors.

Section 14. COMPENSATION OF DIRECTORS. Directors and members of committees of the board may be compensated for their services, and shall be reimbursed for expenses, as fixed or determined by resolution of the board of directors. This section shall not preclude any director from serving the corporation as an officer, agent, employee, or in any other capacity, and receiving compensation for those services.

Section 15. REIMBURSEMENT OF NONDEDUCTIBLE COMPENSATION. If all or part of the compensation, including expenses, paid by the corporation to a director, officer, employee, or agent is finally determined not to be allowable to the corporation as a federal or state income tax deduction, the director, officer, employee, or agent to whom the payment was made shall repay to the corporation the amount disallowed. The board of directors shall enforce repayment of each such amount disallowed by the taxing authorities.

Each board committee shall consist of two or more directors, and may have one or more alternative members, also directors. Appointment of members and alternate members requires the affirmative vote of a majority of the authorized number of directors.

Section 8. REMOVAL AND RESIGNATION OF OFFICERS. Any officer chosen by the board of directors may be removed by the board at any time, with or without cause or notice. Subordinate officers appointed by persons other than the board may be removed at any time, with or without cause or notice, by the board or by the person by whom appointed. A removed officer shall have no claim against the corporation or individual officers or board members arising from such removal (other than any rights he or she may have to monetary compensation or damages under an employment contract).

Any officer may resign at any time by giving the corporation written notice. Unless otherwise specified in the notice, resignations shall take effect on the date the notice is received, and acceptance of the resignation is not necessary to make it effective. An officer’s resignation or its acceptance by the corporation shall not prejudice any rights the corporation may have to monetary damages under an employment contract.

Section 11. REIMBURSEMENT OF NONDEDUCTIBLE COMPENSATION. If all or part of the compensation, including expenses, paid by the corporation to a director, officer, employee, or agent is finally determined not to be allowable to the corporation as a federal or state income tax deduction, the director, officer, employee, or agent to whom the payment was made shall repay to the corporation the amount disallowed. The board of directors shall enforce repayment of each such amount disallowed by the taxing authorities.

ARTICLE VI:INDEMNIFICATION

Section 1. INDEMNIFICATION OF AGENT.

(a) DEFINITIONS. For the purposes of this section, “agent” means any person who is or was a director, officer, employee, or other agent of this corporation or its predecessor, and any person who is or was serving as a director, officer, employee, or agent of another corporation, partnership, joint venture, trust or other enterprise at the request of this corporation or its predecessor; “proceeding” means any threatened, pending, or completed action or proceeding, whether civil, criminal, administrative, or investigative; and “expenses” include but are not limited to attorneys’ fees and any expenses of establishing a right to indemnification under this section.

(b) LAWSUITS OTHER THAN BY THE CORPORATION. This corporation shall have the 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 this corporation to procure a judgment in its favor) by reason of the fact that such person is or was an agent of this corporation, against expenses, judgments, fines, settlements, and other amounts actually and reasonably incurred in connection with such proceeding, if the agent acted in good faith and in a manner the agent reasonably believed to be in the best interests of this corporation. If there are criminal charges, the agent must have had no reasonable cause to believe that his or her conduct was unlawful. The termination of any proceeding by judgment, order, settlement, conviction, or plea of nolo contendere or its equivalent shall not, of itself, create a presumption that the agent did not act in good faith and in a manner that the agent reasonably believed to be in the best interests of this corporation, or that the agent had reasonable cause to believe that his or her conduct was unlawful.

(c) LAWSUITS BY OR ON BEHALF OF THE CORPORATION. This corporation shall have the power to indemnify any person who was, is, or is threatened to be made a party by reason of the fact that that person is or was an agent of this corporation, to any threatened, pending, or completed legal action by or in the right of this corporation to procure a judgment in its favor, against expenses actually and reasonably incurred by the agent in connection with the defense or settlement of that action, if the agent acted in good faith, in a manner the agent believed to be in the best interests of this corporation, and with such care, including reasonable inquiry, as an ordinarily prudent person would use under similar circumstances. However, the corporation shall not indemnify:

(1) Any amount paid with respect to a claim, issue, or matter for which the agent has been adjudged liable to this corporation in the performance of his or her duty, except for any expenses (exclusive of judgment or settlement amount) specifically authorized by the court in which the proceeding is or was pending in accordance with statutory requirements;

-17-

(2) Any amount paid in settling or otherwise disposing of a threatened or pending lawsuit, with or without court approval;

(3) Any expenses incurred in defending a threatened or pending action that is settled or otherwise disposed of without court approval.

(d) SUCCESSFUL DEFENSE BY AGENT. If the agent is successful on the merits, the corporation shall indemnify the agent for expenses actually and reasonably incurred.

(e) APPROVAL; WHEN REQUIRED. Unless indemnification is mandatory because of the agent’s successful defense on the merits, indemnification can be made only as to a specific case, upon a determination that indemnification is proper in the circumstances because the agent has met the applicable standard of conduct, and must be authorized by one of the following: (1) a majority vote of the board with a quorum consisting of directors who are not parties to the proceeding; (2) the affirmative vote of a majority of the outstanding shares entitled to vote and present or represented at a duly held meeting at which a quorum is present or by the written consent of a majority of the outstanding shares entitled to vote (without counting shares owned by the person seeking indemnification as either outstanding or entitled to vote); or (3) the court in which the proceeding is or was pending, upon application by the corporation, the agent, the agent’s attorney, or other person rendering services in connection with the defense, regardless of whether the corporation opposes the application.

(f) ADVANCING EXPENSES. Expenses incurred or to be incurred in defending any proceeding may be advanced by this corporation before the final disposition of the proceeding, on receipt of an undertaking by or on behalf of the agent to repay the amount of the advance, unless it shall be determined ultimately that the agent is entitled to be indemnified as authorized in this section.

(g) OTHER CONTRACTUAL RIGHTS. Nothing contained in this section shall affect any right to indemnification to which persons other than directors and officers of this corporation or any subsidiary may be entitled by contract or otherwise.

-18-

(h) LIMITATIONS. No indemnification or advance shall be made under this section (except where indemnification is required because of the agent’s successful defense on the merits) if it would be inconsistent with (i) a provision of the Articles of Incorporation or bylaws, a resolution of the directors or shareholders, or an agreement in effect at the time the alleged cause of action accrued which prohibits or limits indemnification, or (ii) a condition expressly imposed by a court in approving a settlement.

(i) INSURANCE. If the board of directors so decides, the corporation may purchase and maintain insurance on behalf of any agent of the corporation against any liability asserted against or incurred by the agent in that 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 that liability.

(j) FIDUCIARIES OF EMPLOYEE BENEFIT PLAN. The requirements and limitations imposed by this section do not apply to any proceeding against any trustee, investment manager, or other fiduciary of an employee benefit plan in that person’s capacity as such, even though that person may also be an agent of the corporation. The corporation shall have the power to indemnify, and to purchase and maintain insurance on behalf of, any such trustee, investment manager, or other fiduciary of any benefit plan for any of the corporation’s directors, officers, or employees or those of any of its subsidiary or affiliated corporations. Furthermore, this section shall not limit any right to indemnification that such a trustee, investment manager, or other fiduciary may have as a contract right enforceable by law.

ARTICLE VII:RECORDS AND REPORTS

Section 1. SHAREHOLDER LISTS; INSPECTION BY SHAREHOLDERS. The corporation shall keep at its principal executive office or at the office of its transfer agent or registrar, as the board shall determine, a record of the names and addresses of all shareholders and the number and class of shares held by each.

This list

-19-

shall be made available within 5 days after demand or within 5 days after the specified later date as of which the list is to be compiled.

The record of shareholders shall also be open to inspection during usual business hours, on the written demand of any shareholder or holder of a voting trust certificate, for a purpose reasonably related to the holder’s interest in the corporation. Any inspection or copying under this section may be made in person or by the holder’s agent or attorney.

Section 2. MAINTENANCE OF BYLAWS. The corporation shall keep at its principal executive office, or if its principal executive office is not in California, at its principal business office in this state, the original or a copy of the bylaws as amended to date, which shall be open to inspection by the shareholders at all reasonable times during office hours.

Section 5. ANNUAL REPORT TO SHAREHOLDERS. Inasmuch as, and for as long as, there are less than 100 shareholders, the requirement of an annual report to shareholders referred to in Section 1501 of the California Corporations Code is expressly

-20-

waived. However, nothing in this provision shall be interpreted as prohibiting the board of directors from issuing annual or other periodic reports to the shareholders, as the board considers appropriate.

SECTION 6. FINANCIAL STATEMENTS. The corporation shall keep a copy of any annual financial statement, quarterly or other periodic income statement, and accompanying balance sheets on file in its principal executive office for 12 months; these documents shall be exhibited (or copies provided) to shareholders at all reasonable times. If no annual report for the last fiscal year has been sent to shareholders, on written request of any shareholder made more than 120 days after the close of the fiscal year, the corporation shall deliver or mail to the shareholder, within 30 days after receipt of the request, a balance sheet as of the end of that fiscal year and an income statement and statement of changes in financial position for that fiscal year.

A shareholder or shareholders holding 5 percent or more of the outstanding shares of any class of stock of the corporation may request in writing an income statement for the most recent three-month, six-month, or nine-month period (ending more than 30 days before the date of the request) of the current fiscal year, and a balance sheet as of the end of that period. If such documents are not already prepared, the chief financial officer shall cause them to be prepared and shall deliver them personally or by mail to the requesting shareholders within 30 days after the receipt of the request. A balance sheet, income statement, and statement of changes in financial position for the last fiscal year shall also be included, unless the corporation has sent the shareholders an annual report for the last fiscal year.

Quarterly income statements and balance sheets referred to in this section shall be accompanied by the report, if any, of independent accountants engaged by the corporation, or a certificate by the authorized corporate officer stating that the financial statements were prepared without audit from the corporation’s books and records.

Section 7. ANNUAL INFORMATION STATEMENT. (a) Every year, during the calendar month in which the original Articles of Incorporation were filed with the California Secretary of State or during the preceding five calendar months, the corporation shall file a statement with the Secretary of State on the prescribed form, setting forth the authorized number of directors; the names and complete business or residence addresses of the chief executive officer, the secretary, and the chief financial officer; the street address of the corporation’s principal executive office or principal business office in this state; a statement of the general type of business constituting the principal business activity of the corporation, and a designation

-21-

of the corporation’s agent for service of process, all in compliance with Section 1502 of the Corporations Code of California.

(b) Notwithstanding the provisions of paragraph (a) of this section, if there has been no change in the information contained in the corporation’s last annual statement on file in the Secretary of State’s office, the corporation may, in lieu of filing the annual statement, advise the Secretary of State, on the appropriate form, that no changes in the required information have occurred during the applicable period.

ARTICLE VIII:GENERAL CORPORATE MATTERS

Section 1. RECORD DATE FOR DIVIDENDS AND DISTRIBUTIONS. For purposes of determining the shareholders entitled to receive payment of dividends or other distributions or allotment of rights, or entitled to exercise any rights in respect of any other lawful action (other than voting at and receiving notice of shareholders’ meetings and giving written consent of the shareholders without a meeting), the board of directors may fix, in advance, a record date not more than 60 nor less than 10 days before the date of the dividend payment, distribution, allotment, or other action. If a record date is so fixed, only shareholders of record at the close of business on that date shall be entitled to receive the dividend, distribution, or allotment of rights, or to exercise the other rights, as the case may be, notwithstanding any transfer of any shares on the corporate books after the record date, except as otherwise provided by statute.

If the board of directors does not so fix a record date in advance, the record date for these purposes shall be at the close of business on the later of (a) the day on which the board of directors adopts the applicable resolution or (b) the 60th day before the date of the dividend payment, distribution, allotment of rights, or other action.

Section 2. AUTHORIZED SIGNATORIES FOR CHECKS. All checks, drafts, or other orders for payment of money, notes, and other evidences of indebtedness issued in the name of or payable to the corporation shall be signed or endorsed in the manner and by the persons authorized, from time to time, by the board of directors.

Section 3. EXECUTING CONTRACTS AND INSTRUMENTS. The board of directors, except as otherwise provided in these bylaws, may authorize any of its officers or agents to enter into any contract or execute any instrument in the name of and on behalf of the corporation. This authority may be general or it may be confined to one or more specific matters. No officer, agent, employee, or other person purporting to act on behalf of the corporation shall have any power or authority to bind the corporation

-22-

in any way, pledge its credit, or render it liable for any purpose in any amount, unless that person was acting with authority duly granted by the board of directors as provided in these bylaws, or unless an unauthorized act was later ratified by the corporation.

Section 4. SHARE CERTIFICATES. One or more certificates for shares of the capital stock of the corporation shall be issued to each shareholder when any of the shareholder’s shares are fully paid.

All certificates shall certify the number of shares and the class or series of shares represented by the certificate. All certificates shall be signed in the name of the corporation by (a) one of the following: the chairman or vice chairman of the board of directors, the president, or any vice president; and (b) one of the following: the chief financial officer, any assistant treasurer, the secretary, or any assistant secretary. Any of the signatures on the certificate may be facsimile. If a party who has signed share certificates ceases to be an officer or other agent before the certificate is issued, the corporation may issue the certificate with the same effect as if that person were an officer, transfer agent, or registrar at the date of issue.

The share certificates shall state, by way of appropriate legend, any restrictions on share ownership or transfer, and any other statements required by applicable federal or state securities regulations.

Section 5. LOST CERTIFICATES. Except as provided in this section, no new certificates for shares shall be issued to replace old certificates unless the old certificates are surrendered to the corporation for cancellation at the same time. If share certificates or certificates for any other security have been lost, stolen, or destroyed, the board of directors may authorize the issuance of replacement certificates on terms and conditions as the board may require, which may include a requirement that the owner give the corporation a bond or other adequate security sufficient to protect the corporation against any claim that may be made against it (including any expenses or liability) on account of the alleged loss, theft, or destruction of the old certificate or the issuance of the replacement certificate.

Section 6. SHARES OF OTHER CORPORATIONS: HOW VOTED. Shares of other corporations standing in the name of this corporation shall be voted by the chief executive officer or a person designated by the chief executive officer. If neither of them is able to act, the shares may be voted by a person designated by the board of directors. The authority to vote shares includes the authority to execute a proxy in the corporation’s name for purposes of voting the shares.
