Meetings of Shareholders

Section 1. Place of Meetings. Meetings of shareholders shall be held at any place within or outside the State of California designated by the board of directors. In the absence of any such designation, shareholders’ meetings shall be held at the principal executive office of the corporation.

Section 2. Annual Meeting. The annual meeting of shareholders shall be held each year on a date and at a time designated by the board of directors. The date so designated shall be within fifteen (15) months after the last annual meeting. At each annual meeting directors shall be elected and any other proper business may be transacted.

Section 3. Special Meeting. A special meeting of the shareholders may be called at any time by the board of directors, or by the chairman of the board, or by the president, or by one or more shareholders holding shares in the aggregate entitled to cast not less than ten percent (10%) of the votes at that meeting.

If a special meeting is called by any person or persons other than the board of directors, the request shall be in writing, specifying the time of such meeting and the general nature of the business proposed to be transacted, and shall be delivered personally or sent by registered mail or by telegraphic or other facsimile transmission to the chairman of the board, the president, any vice president or the secretary of the corporation. The officer receiving the request shall cause the notice to be promptly given to the shareholders entitled to vote, in accordance with the provisions of Sections 4 and 5 of this Article III, that a meeting will be held at the time requested by the person or persons calling the meeting not less than thirty-five (35) nor more than sixty (60) days after the receipt of the request. If the notice is not given within twenty (20) days after receipt of the request, the person or persons requesting the meeting may give the notice. Nothing contained in this paragraph of this Section 3 shall be construed as limiting, fixing or affecting the time when a meeting of shareholders called by action of the board of directors may be held.

Section 4. Notice of Shareholders’ Meetings. All notices of meetings of shareholders shall be sent or otherwise given in accordance with Section 5 of this Article III not less than ten (10) nor more than sixty (60) days before the date of the meeting. The notice shall specify the place, date and hour of the meeting and (i) in the case of a special meeting, the general nature of the business to be transacted, or (ii) in the case of the annual meeting, those matters which the board of directors, at the time of giving notice, intends to present for action by the shareholders. The notice of any meeting at which directors are to be elected shall include the name of any nominee or nominees whom, at the time of the notice, management intends to present for election.

If action is proposed to be taken at any meeting for approval of (i) a contract or transaction in which a director has a direct or indirect financial interest within the meaning of Section 310 of the Corporations Code of California, (ii) an amendment of the articles of incorporation pursuant to Section 902 of the Code, (iii) a reorganization of the corporation pursuant to Section 1201 of that Code, (iv) a voluntary dissolution of the corporation pursuant to Section 1900 of that Code, or (v) a distribution in dissolution other than in accordance with the rights of outstanding preferred shares pursuant to Section 2007 of that Code, the notice shall also state the general nature of that proposal.

Section 5. Manner of Giving Notice; Affidavit of Notice. Notice of any meeting of shareholders shall be given either personally or by first-class mail or telegraphic or other written communication, charges prepaid, addressed to the shareholder at the address of that shareholder appearing on the books of the corporation or given by the shareholder to the corporation for the purpose of notice. If no such address appears on the corporation’s books or is so given, notice shall be deemed to have been given if sent to that shareholder by first-class mail or telegraphic or other written communication to the corporation’s principal executive office, or if published at least once in a newspaper of general circulation in the county where that office is located. Notice shall be deemed to have been given at the time when delivered personally or deposited in the mail or sent by telegram or other means of written communication.

If any notice addressed to a shareholder at the address of that shareholder appearing on the books of the corporation is returned to the corporation by the United States Postal Service marked to indicate that the United States Postal Service is unable to deliver the notice to the shareholder at that address, all future notices or reports shall be deemed to have been duly given without further mailing if these shall be available to the shareholder on written demand of the shareholder at the principal executive office of the corporation for a period of one (1) year from the date of the giving of the notice.

An affidavit of the mailing or other means of giving any notice of any shareholders’ meeting shall be executed by the secretary, assistant secretary or any transfer agent of the corporation giving the notice, and shall be filed and maintained in the minute book of the corporation.

Section 6. Quorum. The presence in person or by proxy of the holders of a majority of the shares entitled to vote in 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 is present may continue to do business until adjournment, notwithstanding the withdrawal of enough shareholders to leave less than a quorum, if any action taken (other than adjournment) is approved by at least a majority of the shares required to constitute a quorum.

Section 7. Adjourned Meeting; Notice. Any shareholders’ meeting, annual or special, whether or not a quorum is present, may be adjourned from time to time by the vote of the majority of the shares represented at that meeting, either in person or by proxy, but in the absence of a quorum, no other business may be transacted at that meeting, except as provided in Section 6 of this Article III.

When any meeting of shareholders, either annual or special, is adjourned to another time or place, notice need not be given of the adjourned meeting if the time and place are announced at a meeting at which the adjournment is taken, unless a new record date for the adjourned meeting is fixed, or unless the adjournment is for more than forty-five (45) days from the date set for the original meeting, in which case the board of directors shall set a new record date. Notice of any such adjourned meeting shall be given to each shareholder of record entitled to vote at the adjourned meeting in accordance with the provisions of Sections 4 and 5 of this Article III. At any adjourned meeting the corporation may transact any business which might have been transacted at the original meeting.

Section 8. Voting. The shareholders entitled to vote at any meeting of shareholders shall be determined in accordance with the provisions of Section 11 of this Article III, subject to the provisions of Sections 702 to 704, inclusive, of the Corporations Code of California (relating to voting shares held by a fiduciary, in the name of a corporation or in joint ownership). The shareholders’ vote may be by voice vote or by ballot; provided, however, that any election for directors must be by ballot if demanded by any shareholder before the voting has begun. On any matter other than elections of directors, any shareholder may vote part of the shares in favor of the proposal and refrain from voting the remaining shares or vote them against the proposal, but, if the shareholder fails to specify the number of shares which the shareholder is voting affirmatively, it will be conclusively presumed that the shareholder’s approving vote is with respect to all shares that the shareholder is entitled to vote. If a quorum is present, the affirmative vote of the majority of the shares represented at the meeting and entitled to vote on any matter (other than the election of directors) shall be the act of the shareholders, unless the vote of a greater number or voting by classes is required by California General Corporation Law or by the articles of incorporation or by these bylaws.

At a shareholders’ meeting at which directors are to be elected, no shareholder shall be entitled to cumulate votes (i.e., cast for any one or more candidates a number of votes greater than the number of the shareholder’s shares) unless the candidates’ names have been placed in nomination prior to commencement of the voting and a shareholder has given notice prior to commencement of the voting of the shareholder’s intention to cumulate votes. If any shareholder has given such a notice, then every shareholder entitled to vote may cumulate votes for candidates in nomination 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 that shareholder’s shares are entitled, or distribute the shareholder’s votes on the same principle among any or all of the candidates, as the shareholder thinks fit. The candidates receiving the highest number of votes, up to the number of directors to be elected, shall be elected.

Section 9. Waiver of Notice of Consent by Absent Shareholders. The transactions of any meeting of shareholders, either annual or special, however called and noticed and wherever held, shall be as valid as though had a meeting duly held after regular call and notice, if a quorum be present either in person or by proxy, and if, either before or after the meeting, each person entitled to vote who was not present in person or by proxy, or who, though present, has at the beginning of the meeting properly objected to the transaction of any business because the meeting was not lawfully called or convened, or to particular matters of business legally required to be included in the notice but not so included, signs a written waiver of notice or a consent to a holding of the meeting or an approval of the minutes. The waiver of notice or consent need not specify either the business to be transacted or the purpose of any annual or special meeting of shareholders, except that if action is taken or proposed to be taken for approval of any of those matters specified in the second paragraph of Section 4 of this Article III, the waiver of notice or consent shall state the general nature of the proposal. All such waivers, consents or approvals shall be filed with the corporate records or made a part of the minutes of the meeting.

Section 10. Shareholder Action by Written Consent Without a Meeting. Any action which may be taken at any annual or special meeting of shareholders 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 not less than the minimum number of votes that would be necessary to authorize or take that action at a meeting at which all shares entitled to vote on that action were present and voted. In the case of election of directors, such a consent shall be effective only if signed by the holders of all outstanding shares entitled to vote for the election of directors; provided, however, that a director may be elected at any time to fill a vacancy on the board of directors that has not been filled by the directors by the written consent of the holders of a majority of the outstanding shares entitled to vote for the election of directors. All such consents shall be filed with the secretary of the corporation and shall be maintained in the corporate records. Any shareholder giving a written consent, or the shareholder’s proxy holders, or a transferee of the shares, or a personal representative of the shareholder or their respective proxy holders may revoke the consent 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.

If the consents of all shareholders entitled to vote have not been solicited in writing and if the unanimous written consent of all such shareholders shall not have been received, the secretary shall give prompt notice of the corporate action approved by the shareholders without a meeting. This notice shall be given in the manner specified in Section 5 of this Article III. In the case of approval of (i) contracts or transactions in which a director has a direct or indirect financial interest pursuant to Section 310 of the Corporations Code of California, (ii) indemnification of agents of the corporation pursuant to Section 317 of that Code, (iii) a reorganization of the corporation pursuant to Section 1201 of that Code, and (iv) a distribution in dissolution other than in accordance with the rights of outstanding preferred shares pursuant to Section 2007 of that Code, the notice shall be given at least ten (10) days before the consummation of any action authorized by that approval.

Section 11. Record Date for Shareholder Notice, Voting, and Giving Consents. For purposes of determining the shareholders entitled to notice of any meeting or to vote or entitled to give consent to corporate action without a meeting, the board of directors may fix, in advance, a record date which shall not be more than sixty (60) days nor less than ten (10) days before the date of any such meeting nor more than sixty (60) days before any such action without a meeting, and in this event only shareholders of record on the date so fixed are entitled to notice and to vote or to give consents, as the case may be, notwithstanding any transfer of any shares on the books of the corporation after the record date, except as otherwise provided in the California General Corporation Law.

If the board of directors does not so fix a record date:

(a) The record date for determining shareholders entitled to notice of or to vote at a meeting of shareholders shall be at the close of business on the business day next preceding the day on which notice is given or, if notice is waived, at the close of business on the business day next preceding the day on which the meeting is held.

(b) The record date for determining shareholders entitled to give consent to corporate action in writing without a meeting (i) when no prior action by the board has been taken, shall be the day on which the first written consent is given, or (ii) when prior action of the board has been taken, shall be at the close of business on the day on which the board adopts the resolution relating to that action, or the sixtieth (60th) day before the date of such other action, whichever is later.

Section 12. 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 which does not state that it is irrevocable shall continue in full force and effect unless (i) revoked by the person executing it, before the vote pursuant to that proxy, by a writing delivered to the corporation stating that the proxy is revoked, or by a subsequent proxy executed by, or attendance at the meeting and voting in person by, the person executing the proxy; or (ii) written notice of the death or incapacity of the maker of that proxy is received by the corporation before the vote pursuant to that proxy is counted; provided, however, that no proxy shall be valid after the expiration of eleven (11) months from the date of the proxy unless otherwise provided in the proxy. The revocability of a proxy that states on its face that it is irrevocable shall be governed by the provisions of Sections 705(e) and 705(f) of the Corporations Code of California.

Section 13. Inspectors of Election. Before any meeting of shareholders, the board of directors may appoint any persons other than nominees for office to act as inspectors of election at the meeting or its adjournment. If no inspectors of election are so appointed, the chairman of the meeting may, and on the request of any shareholder or a shareholder’s proxy shall, appoint inspectors of election at the meeting. The number of inspectors shall be either one (1) or three (3). If inspectors are appointed at a meeting on the request of one or more shareholders or proxies, the holders of a majority of shares or their proxies present at the meeting shall determine whether one (1) or three (3) inspectors are to be appointed. If any person appointed as inspector fails to appear or fails or refuses to act, the chairman of the meeting may, and upon the request of any shareholder or a 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 IV

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 action required to be approved 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 directors shall have the power to:

(a) select and remove all officers, agents and employees of the corporation; prescribe any powers and duties for them that are consistent with law, with the articles of incorporation and with these bylaws; fix their compensation; and require from them security for faithful service.

(b) change the principal executive office or the principal business office in the State of California from one location to another; cause the corporation to be qualified to do business in any other state, territory, dependency or country and conduct business within or without the State of California; and designate any place within or without the State of California for the holding of any shareholders’ meeting or meetings, including annual meetings.

(c) adopt, make and use a corporate seal; prescribe the forms of certificates of stock; and alter the form of the seal and certificates.

Section 2.¹ Number and Qualification of Directors. The number of directors of the corporation shall be not less than seven (7) nor more than thirteen (13). The exact number of directors shall be nine (9) until changed, within the limits specified above, by a bylaw amending this Section 2, duly adopted by the board of directors or by the shareholders. The indefinite number of directors may be changed, or a definite number fixed without provision for an indefinite number, by a duly adopted amendment to the articles of incorporation or by an amendment to this bylaw duly adopted by the vote or written consent of holders of a majority of the outstanding shares entitled to vote; subject, however, to such additional voting requirement or limitation as is imposed under applicable law in the case of an amendment reducing the number of directors to a number less than five (5).

Section 3. Independent Directors. A majority of directors of the corporation shall be Independent Directors, except for a period of 90 days after the death, removal or resignation of an Independent Director.

Section 4. Election and Term of Office of Directors. Directors shall be elected at each annual meeting of the shareholders 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.

Section 5. Vacancies. Except as otherwise agreed by the corporation, vacancies in the board of directors may be filled by a majority of the remaining directors, though less than a quorum, or by a sole remaining director, except that a vacancy created by the removal of a director by the vote or written consent of the shareholders or by court order may be filled only by the vote of a majority of the shares entitled to vote represented at a duly held meeting at which a quorum is present, or by the written consent of holders of a majority of the outstanding shares entitled to vote. Each director so elected shall hold office until the next annual meeting of the shareholders and until a successor has been elected and qualified.

A vacancy or vacancies in the board of directors shall be deemed to exist in the event of the death, resignation or removal of any director, or if the board of directors by resolution declares vacant the office of a director who has been declared of unsound mind by an order of court or convicted of a felony, or if the authorized number of directors is increased, or if the shareholders fail, at any meeting of shareholders at which any director or directors are elected, to elect the number of directors to be voted for at that meeting.

The shareholders may elect a director or directors at any time to fill any vacancy or vacancies not filled by the directors, but any such election by written consent shall require the consent of a majority of the outstanding 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 time for that resignation to become effective. If the resignation of a director is effective at a future time, the board of directors may elect a successor to take office when the resignation becomes effective.

No reduction of the authorized number of directors shall have the effect of removing any director before that director’s term of office expires.

Section 6. Place of Meetings and Meetings by Telephone. Regular meetings of the board of directors may be held at any place within or outside the State of California that has been designated from time to time by resolution of the board. In the absence of such a designation, regular meetings shall be held at the principal executive office of the corporation. Special meetings of the board shall be held at any place within or outside the State of California that has been designed in the notice of the meeting or, if not stated in the notice or there is no notice, at the principal executive office of the corporation. Any meeting, regular or special, may be held by conference telephone or similar communication equipment, so long as all directors participating in the meeting can hear one another, and all such directors shall be deemed to be present in person at the meeting.

Section 8. Other Regular Meetings. Other regular meetings of the board of directors shall be held without call at such time as shall from time to time be fixed by the board of directors. Such regular meetings may be held without notice.

In case the notice is mailed, it shall be deposited in the United States mail at least four (4) days before the time of the holding of the meeting. In case the notice is delivered personally or by telephone or telegram, it shall be delivered personally or by telephone or to the telegraph company at least forty-eight (48) hours before the time of the holding of the meeting. Any oral notice given personally or by telephone may be communicated either to the director or to a person at the office of the director who the person giving the notice has reason to believe will promptly communicate it to the director. The notice need not specify the purpose of the meeting. In addition, the place of the meeting need not be specified if it is to be held at the principal executive office of the corporation.

Section 10. Quorum. A majority of the authorized number of directors shall constitute a quorum for the transaction of business, except to adjourn as provided in Section 12 of this Article IV. Every act or decision done or made by a majority of the directors present at a meeting duly held at which a quorum is present shall be regarded as the act of the board of directors, subject to the provisions of Section 310 of the Corporations Code of California (as to approval of contracts or transactions in which a director has a direct or indirect material financial interest), Section 311 of that Code (as to appointment of committees), and Section 317(e) of that Code (as to indemnification of directors). A meeting at which a quorum is initially present may continue to transact business notwithstanding the withdrawal of directors, if any action taken is approved by at least a majority of the required quorum for that meeting.

Section 11. Waiver of Notice. The transactions of any meeting of the board of directors, however called and noticed or wherever held, shall be as valid as though had at a meeting duly held after regular call and notice if a quorum is present and if, either before or after the meeting, each of the directors not present or who though present or who though present has prior to the meeting or at its commencement protested the lack of proper notice to him, signs a written waiver of notice, a consent to holding the meeting or an approval of the minutes. The waiver of notice or consent need not specify the purpose of the meeting. All such waivers, consents and approvals shall be filed with the corporate records or made a part of the minutes of the meeting.

Section 14. Action Without Meetings. 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 shall individually or collectively consent in writing to that action. Such action by written consent shall have the same force and effect as a unanimous vote of the board of directors. Such written consent or consents shall be filed with the minutes of the proceedings of the board.

Section 15. Fees and Compensation of Directors. Directors and members of committees may receive such compensation, if any, for their services and such reimbursement of expenses as may be fixed or determined by resolution of the board of directors. This Section 15 shall not be construed to preclude any director from serving the corporation in any other capacity as an officer, agent, employee or otherwise, and receiving compensation for those services.

The board of directors may, by resolution adopted by a majority of the authorized number of directors, designate one or more committees, each consisting of two or more directors, to serve at the pleasure of the board. The board may designate one or more directors as alternate members of any committee who may replace any absent member at any meeting of the committee. Any committee, to the extent provided in the resolution of the board, shall have all the authority of the board, except with respect to:

ARTICLE IX

General Corporate Matters

Section 1. Record Date for Purposes Other than Notice and Voting. For purposes of determining the shareholders 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 other lawful action (other than action by shareholders by written consent without a meeting), the board of directors may fix, in advance, a record date which shall not be more than sixty (60) days before any such action, and in that case only shareholders of record on the date so fixed are entitled to receive the dividend, distribution or allotment of rights or to exercise the rights, as the case may be, notwithstanding any transfer of any shares on the books of the corporation after the record date so fixed, except as otherwise provided in the California General Corporation law.

If the board of directors does not so fix a record date, the record date for determining shareholders for any such purpose shall be at the close of business on the day on which the board adopts the applicable resolution or the sixtieth (60th) day before the date of that action, whichever is later.

Section 2. Checks, Drafts, Evidence of Indebtedness. All checks, drafts or other orders for payment of money, notes or other evidences of indebtedness, issued in the name of or payable to the corporation, shall be signed or endorsed by such person or persons and in such manner as set from time to time shall be determined by resolution of the board of directors.

Section 3. Corporate Contracts and Instruments; How Executed. The board of directors, except as otherwise provided in these bylaws, may authorize any officer or officers, agent or agents, to enter into any contract or execute any instrument in the name of and on behalf of the corporation, and this authority may be general or confined to specific instances; and, unless so authorized or ratified by the board of directors or within the agency power of an officer, 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 for any amount.

Section 4. Certificates for Shares. Each shareholder shall be entitled to a certificate or certificates for shares of the capital stock of the corporation signed in the name of the corporation by the chairman of the board or vice chairman of the board, or the president or vice president, and by the chief financial officer or an assistant treasurer or the secretary or any assistant secretary, certifying the number of shares and the class or series of shares owned by the shareholder. 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 on a certificate shall have ceased to be that officer, transfer agent or registrar before that certificate is issued, it may be issued by the corporation with the same effect as if that person were an officer, transfer agent or registrar at the date of issue.

Section 5.² Stock Certificates and Uncertificated Stock. Shares of the corporation’s stock may be certificated or uncertificated, as provided under California law. Every certificate of stock of the corporation shall be signed in the name of the corporation by the chairman of the board or vice chairman of the board, or the president or a vice president, and by the chief financial officer or an assistant treasurer or the secretary or any assistant secretary, certifying the number of shares and the class or series of shares owned by the shareholder. 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 on a certificate shall have ceased to be that officer, transfer agent or registrar before that certificate is issued, it may be issued by the corporation with the same effect as if that person were an officer, transfer agent or registrar at the date of issue.

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

Section 6.² Lost Certificates. The board of directors may, in case any share certificate or certificate for any other security is alleged to have been lost, stolen, or destroyed, authorize the issuance of a replacement certificate or uncertificated shares in lieu thereof on such terms and conditions as the board may require, including provision for indemnification of the corporation secured by a bond or other adequate security sufficient to protect the corporation against any claim that may be made against it, including any expense or liability, on account of the alleged loss, theft or destruction of the certificate or the issuance of the replacement certificate or uncertificated shares.

Section 7. Restrictions on Transactions with Affiliates. The corporation may engage in transactions with affiliates provided that a purchase or sale transaction with an affiliate is (i) approved by a majority of the corporation’s Independent Directors and (ii) fair to the corporation based on an independent appraisal or fairness opinion.

Section 8. Repurchase of Shares. The corporation may purchase or reacquire its shares and invest its assets in its own shares, provided that in each case the consent of the board of directors shall have been obtained.

Section 9. Provisions in Conflict with Law or Regulations. The provisions of these bylaws are severable, and if the directors shall determine, with the advice of counsel, that any one or more of such provisions (the “Conflicting Provisions”) are in conflict with the provisions of Section 850 through 860 of the Code or with other applicable federal or California laws and regulations, the Conflicting Provisions shall be deemed never to have constituted a part of these bylaws; provided, however, that such determination by the directors shall not affect or impair any of the remaining provisions of these bylaws or render invalid or improper any action taken or omitted (including but not limited to the election of directors) prior to such determination. Such determination shall become effective when a certificate signed by a majority of the directors setting forth any such determination and reciting that it was duly adopted by the directors, shall be filed with the books and records of the corporation. The directors shall not be liable for failure to make any determination under this Section. Nothing in this Section shall in any way limit or affect the right of the directors or the shareholders to amend these bylaws.

Section 10. Construction. Unless the context requires otherwise, the general provisions, rules of construction and definitions in the California General Corporation Law shall govern the construction of these bylaws.

Section 11. Proposal for Sale or Financing of Properties. During 1997, unless shareholders had previously approved such a proposal, the shareholders will be presented with a proposal to approve or disapprove (a) the sale or financing of all or substantially all of the corporation’s properties and (b) the distribution of the proceeds from such transaction and, in the case of a sale, the liquidation of the corporation, unless the proceeds of such sale include deferred payments, in which case the corporation would be liquidated following receipt of all deferred payments; provided, however, that this provision shall not be applicable if the merger of American Office Park Properties, Inc. into the corporation is completed. This provision may not be amended or repealed without the vote or written consent of holders of a majority of the outstanding shares entitled to vote.

Section 2. Amendment by Directors. Subject to the rights of the shareholders as provided in Section 1 of this Article XI, to adopt, amend or repeal bylaws, bylaws may be adopted, amended or repealed by the board of directors; provided, however, that after the issuance of shares, the board of directors may adopt a bylaw or amendment of a bylaw changing the authorized number of directors only for the purpose of fixing the exact number of directors within the limits specified in the articles of incorporation or in Section 2 of Article IV of these bylaws, and provided further that bylaws relating to the corporation’s qualification as a real estate investment trust (Section 9 of Article IX), bylaws requiring that a majority of the directors be Independent Directors (Section 3 of Article IV), bylaws relating to restrictions on transactions with affiliates (Section 7 of Article IX) and bylaws relating to restrictions on the repurchase by the corporation of its shares (Section 8 of Article IX), may not be amended or repealed without the vote or written consent of holders of a majority of the outstanding shares entitled to vote.
