(a California corporation)

ARTICLE I

OFFICES

Section 1.1 PRINCIPAL OFFICES. The Board of Directors shall fix the location of the principal executive office (the “Head Office”) of the Corporation at any place within or outside the State of California. If the Head Office is located outside this state, and the Corporation has one or more business offices in this state, the Board of Directors shall designate a principal business office in the State of California.

Section 1.2 CHANGE IN LOCATION OR NUMBER OF OFFICES. The Board of Directors may change any office from one location to another or establish or eliminate any office or offices.

ARTICLE II

MEETINGS OF SHAREHOLDERS

Section 2.1 PLACE OF MEETINGS. Meetings of the shareholders shall be held at any place within or without the State of California designated by the Board of Directors, or, in the absence of such designation, at the Head Office of the Corporation. If authorized by the Board of Directors in its sole discretion, and subject to the requirement of consent as described below and those guidelines and procedures as the Board of Directors may adopt, shareholders not physically present in person or by proxy at a meeting of shareholders may, by “electronic transmission by and to the Corporation” as defined below, or by electronic video screen communication, participate in a meeting of shareholders, be deemed present in person or by proxy, and vote at a meeting of shareholders whether that meeting is to be held at a designated place or in whole or in part by means of electronic transmission by and to the Corporation or by electronic video screen communication.

“Electronic transmission by the Corporation” means (i) a facsimile telecommunication or electronic mail when directed to the facsimile number or electronic mail address, respectively, for that recipient on record with the Corporation, (ii) posting on an electronic message board or network which the Corporation has designated for those communications, together with a separate notice to the recipient of the posting, which transmission shall be validly delivered upon the later of the posting or delivery of the separate notice thereof, or (iii) other means of electronic communication. In all cases of electronic transmissions, the recipient must have provided an unrevoked consent to the use of those means of transmission for such communications, and the means of transmission must create a record that is capable of retention, retrieval, and review, and that may thereafter be rendered into clearly legible tangible

1

form. However, an electronic transmission to an individual shareholder is not authorized unless, in addition to satisfying the requirements of this section, the transmission satisfies the requirements applicable to consumer consent to electronic records as set forth in the Electronic Signatures in Global and National Commerce Act (15 U.S.C. Sec. 7001(c)(1)).

“Electronic transmission to the Corporation” means (i) a facsimile telecommunication or electronic mail when directed to the facsimile number or electronic mail address, respectively, which the Corporation has provided from time to time to shareholders for sending communications to the corporation, (ii) posting on an electronic message board or network which the Corporation has designated for those communications, and which transmission shall be validly delivered upon the posting, or (iii) other means of electronic communication. In all cases of electronic transmissions to the Corporation, the Corporation must have placed in effect reasonable measures to verify that the sender is the shareholder (in person or by proxy) purporting to send the transmission, and the means of transmission must create a record that is capable of retention, retrieval, and review, and that may thereafter be rendered into clearly legible tangible form.

A meeting of the shareholders may be conducted, in whole or in part, by electronic transmission by and to the Corporation as defined above or by electronic video screen communication if (i) the Corporation implements reasonable measures to provide shareholders (in person or by proxy) a reasonable opportunity to participate in the meeting and to vote on matters submitted to the shareholders, including an opportunity to read or hear the proceedings of the meeting concurrently with those proceedings; and (ii) if any shareholder votes or takes other action at the meeting by means of electronic transmission to the Corporation or electronic video screen communication, a record of that vote or action is maintained by the Corporation. Any request by a Corporation to a shareholder for consent to conduct a meeting of shareholders by electronic transmission shall include a notice that absent consent of the shareholder, the meeting shall be held at a physical location in accordance with the first paragraph of this Section 2.1.

Section 2.2 ANNUAL MEETINGS.

(a) Date and Time. 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.

(b) Business to be Transacted. At the Annual Meeting, directors shall be elected, reports of the affairs of the Corporation shall be considered, and any other business may be transacted which is within the powers of the shareholders.

(c) Notice, Means. Notice of each Annual Meeting shall be given to each shareholder entitled to vote, either personally, by electronic transmission by the Corporation as defined in Section 2.1 above, or by first-class mail, charges prepaid, addressed to such shareholder at his address appearing on the books of the Corporation or given by him to the Corporation for the purpose of notice. If a shareholder gives no address, notice shall be deemed to have been given him if sent by mail or other means of written communication addressed to the place where the Head Office of the Corporation is situated, or if published at least once in some newspaper of general

2

circulation in the county in which the Head Office is located. An affidavit of the mailing or other means of giving any notice of any Annual 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.

If any notice or report addressed to the shareholder at the address of such 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 or report to the shareholder at such address, all future notices or reports shall be deemed to have been duly given without further mailing if the same shall be available for the shareholder upon written demand of the shareholder at the Head Office of the Corporation for a period of one year from the date of the giving of the notice or report to all other shareholders. Notice given by electronic transmission by the Corporation under this subdivision shall be valid only if it complies with the requirements set forth in Section 2.1 above. Notwithstanding the foregoing, notice shall not be given by electronic transmission by the Corporation under this subdivision after either of the following: (i) the Corporation is unable to deliver two consecutive notices to the shareholder by that means; or (ii) the inability to so deliver the notices to the shareholder becomes known to the secretary, any assistant secretary, the transfer agent, or other person responsible for the giving of the notice.

(d) Notice, Time and Content. All notices referred to in subsection (c) above shall be given to each shareholder entitled thereto by electronic transmission as defined in Section 2.1 above, or first-class mail not less than ten (10) days nor more than sixty (60) days before each Annual Meeting. Any such notice shall be deemed to have been given at the time when delivered personally or deposited in the mail or sent by other means of written communication.

Such notices shall specify:

(i) the place, the date, and the hour of such meeting;

(ii) the means of electronic transmission by and to the corporation or electronic video screen communication, if any, by which shareholders may participate in that meeting,

(iii) those matters which the Board, at the time of the mailing of the notice, intends to present for action by the shareholders;

(iv) if directors are to be elected, the names of nominees intended at the time of the notice to be presented by management for election;

(v) the general nature of a proposal, if any, to take action with respect to approval of, (a) a contract or other transaction with an interested director, (b) amendment of the Articles of Incorporation, (c) a reorganization of the Corporation as defined in Section 181 of the General Corporation Law, (d) voluntary dissolution of the Corporation, or (e) a distribution in dissolution other than in accordance with the rights of outstanding preferred shares, if any; and

(vi) such other matters, if any, as may be expressly required by statute.

Nominations for election of members of the Board of Directors may be made by the Board of Directors or by any shareholder entitled to vote for the election of directors. Notice of intention to make any nominations by a shareholder shall be made in writing and shall be delivered or mailed to and received by the Secretary of the Corporation not less than one hundred twenty (120) calendar days in advance of the date corresponding to that on which the Corporation’s proxy statement was released to the shareholders in connection with the previous year’s annual meeting of shareholders; provided, however, that in the event that no annual meeting was held in the previous year or the date of the annual meeting has been changed by more than thirty (30) days from the date contemplated at the time of the previous year’s proxy statement, notice by the shareholder must be received by the Secretary of the Corporation not later than the close of business on the later of (i) one hundred and twenty (120) days prior to such annual meeting; or (ii) ten (10) days after the date the notice of such meeting is sent to shareholders pursuant to Section 2.2(d) of these Bylaws. In no event shall the notice of an adjournment or postponement of an annual meeting commence a new time period (or extend any time period) for the giving of shareholder’s notice as described above. Such notification shall contain the following information to the extent known to the notifying shareholder: (a) the name and address of each proposed nominee; (b) the principal occupation of each proposed nominee; (c) the number of shares of voting stock of the Corporation owned by each proposed nominee; (d) the name and residence address of the notifying shareholder and the beneficial owner, if any, on whose behalf the nomination is made; and (e) the number of shares of voting stock of the Corporation owned beneficially and of record by the notifying shareholder and such beneficial owner. Nominations not made in accordance herewith shall be disregarded by the chairman of the meeting, and the inspectors of election shall then disregard all votes cast for each such nominee.

The first paragraph of this Section 2.3 or a summary thereof shall be set forth in either the notice or related proxy statement concerning any shareholders’ meeting at which the election of directors is to be considered.

Section 2.4 SPECIAL MEETINGS.

(a) Calling of. Special meetings of the shareholders, for the purpose of taking any action permitted by the shareholders under the General Corporation Law and the Articles of Incorporation of this Corporation, may be called at any time by the Chairman of the Board, the President, the Board of Directors, or by one or more shareholders holding not less than ten percent (10%) of the outstanding shares entitled to vote.

(b) Time and Notice of. Upon receipt of a request in writing that a special meeting of shareholders be called for any proper purpose, directed to the Chairman of the Board, President, Vice President or Secretary by any person (other than the Board) entitled to call a special meeting of shareholders, then such officer shall forthwith cause notice to be given to shareholders entitled to vote that a meeting will be held at a time requested by the person or persons calling the meeting, which time shall be not less than thirty-five (35) nor more than sixty (60) days after receipt of the request. If such notice is not given within twenty (20) days after receipt of such request, the persons calling for the meeting may give notice thereof in the manner provided by these Bylaws or apply to the Superior

4

Court for an order requiring the giving of such notice, as provided in the General Corporation Law. Except in special cases where other express provision is made by statute, notice of such special meetings shall be given in the same manner as for Annual Meetings of Shareholders. In addition to the matters required by item (d)(i) and, if applicable, item (d)(iii) of Section 2.2 of these Bylaws, notice of any special meeting shall specify the general nature of the business to be transacted, and no other business may be transacted at such meeting.

Section 2.5 QUORUM. A majority of the shares entitled to vote, represented in person or by proxy, shall constitute a quorum for the transaction of business at any meeting of shareholders. 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 2.6 ADJOURNED MEETING AND NOTICE THEREOF. Any shareholders’ meeting, annual or special, whether or not a quorum is present, may be adjourned from time to time by the vote of a majority of the shares, the holders of which are either present in person or represented by proxy thereat, but in the absence of a quorum no other business may be transacted at such meeting, except as provided in Section 2.5 above. When any shareholders’ meeting, either annual or special, is adjourned for forty-five (45) days or more, or if after adjournment, a new record date is fixed for the adjourned meeting, notice of the adjourned meeting shall be given as in the case of an original meeting. Except as provided above, it shall not be necessary to give any notice of the time and place of the adjourned meeting or of the business to be transacted thereat, other than by announcement of the time and place thereof at the meeting at which such adjournment is taken.

Section 2.7 VOTING.

(a) Record Date. Unless a record date for voting purposes is fixed as provided in Section 8.1 of these Bylaws then, subject to the provisions of the General Corporation Law (relating to voting of shares held by a fiduciary, in the name of a corporation, or in joint ownership), only persons in whose names shares entitled to vote stand on the stock records of the Corporation at the close of business on the business day next preceding the day on which notice of the meeting is given or if such notice is waived, at the close of business on the business day next preceding the day on which the meeting of shareholders is held, shall be entitled to vote at such meeting, and such day shall be the record date for such meeting.

(b) Ballot. Voting may be oral or by written ballot; provided, however, that all elections for directors must be by ballot if demand for election by ballot is made by a shareholder at the meeting and before the voting begins. 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 shall be the act of the shareholders, unless the vote of a greater number or voting by classes is required by the General Corporation Law or the Articles of Incorporation.

5

(c) Voting Rights. Unless otherwise provided in the Articles of Incorporation, each share of common stock shall be entitled to one vote in person or by proxy at any meeting of shareholders. Shareholders do not have cumulative voting rights in connection with the election of directors.

Section 2.8 VALIDATION OF DEFECTIVELY CALLED OR NOTICED MEETINGS. 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 at 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 of the persons entitled to vote, who was not present in person or by proxy, 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, consent or approval 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 Section 2.2(d)(v), the waiver of notice, consent or approval 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.

Attendance by a person at a meeting shall also constitute a waiver of notice of and presence at that meeting, except when the person objects, at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened, and except that attendance at a meeting is not a waiver of any right to object to the consideration of matters not included in the notice of the meeting if that objection is expressly made at the meeting.

Section 2.9 ACTION WITHOUT MEETING.

(a) Election of Directors. Directors may be elected without a meeting by a consent in writing, setting forth the action so taken, signed by all of the persons who would be entitled to vote for the election of directors, provided that, without notice except as hereinafter set forth, a director may be elected at any time to fill a vacancy not filled by the directors by the written consent of persons holding a majority of the outstanding shares entitled to vote for the election of directors.

(b) Other Action. Unless otherwise provided for in the Articles of Incorporation, any action which, under any provision of the General Corporation Law may be taken at a meeting of the shareholders, may be taken without a meeting, and without notice except as hereinafter set forth, 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 such action at a meeting at which all shares entitled to vote thereon were present and voted.

Unless the consents of all shareholders entitled to vote have been solicited in writing: (i) notice of any proposed shareholder approval of (a) a contract or other transaction with an interested director, (b) indemnification of an agent of the Corporation as authorized by Section 3.8 of these Bylaws, (c) a reorganization of the Corporation as defined in the General Corporation Law, or (d) a distribution in dissolution other than in accordance with the rights of outstanding preferred shares, if any, without a meeting by less than unanimous written consent, shall be given at least ten (10) days before the consummation of the action

6

authorized by such approval; and, (ii) prompt notice shall be given of the taking of any other corporate action approved by shareholders without a meeting by less than unanimous written consent, to those shareholders entitled to vote who have not consented in writing. Such notices shall be given in the manner and shall be deemed to have been given as provided in Section 2.2 of these Bylaws.

Unless, as provided in Section 8.1 of these Bylaws, the Board of Directors has fixed a record date for the determination of shareholders entitled to notice of and to give such written consent, the record date for such determination shall be the day on which the first written consent is given. All such written consents shall be filed with the Secretary of the Corporation.

Any shareholder giving a written consent, or the shareholder’s proxyholders, or a transferee of the shares or a personal representative of the shareholder or their respective proxyholders, may revoke the consent by a writing received by the Corporation prior to the time that written consents of the number of shares required to authorize the proposed action have been filed with the Secretary of the Corporation, but may not do so thereafter. Such revocation is effective upon its receipt by the Secretary of the Corporation.

Section 2.10 PROXIES. Every person entitled to vote or execute consents shall have the right to do so either in person or by one or more agents authorized by a written proxy executed by such person or his duly authorized agent and filed with the Secretary of the Corporation. Any proxy duly executed is not revoked and continues in full force and effect until (i) an instrument revoking it or a proxy bearing a later date executed by the person executing the prior proxy is presented to the meeting, (ii) the person executing the proxy attends the meeting and votes in person, or (iii) written notice of the death or incapacity of the maker of such proxy is received by the Corporation before said proxy is voted and counted; provided that no such proxy shall be valid after the expiration of eleven (11) months from the date of its execution, unless otherwise provided in the proxy.

Section 2.11 INSPECTORS OF ELECTION.

(a) Appointment, Number. In advance of any meeting of shareholders, the Board of Directors may appoint any persons, other than nominees for office, as inspectors of election to act at such meeting or any adjournment thereof. If inspectors of election are not so appointed, or if any person so appointed fails to appear or refuses to act, the chairman of any such meeting may, and on the request of any shareholder or his proxy shall, make such appointment at the meeting as provided in the General Corporation Law. The number of inspectors shall be either one (1) or three (3). If appointed at a meeting on the request of one or more shareholders or proxies, the majority of shares represented in person or by proxy shall determine whether one (1) or three (3) inspectors are to be appointed.

(b) Duties. The duties of such inspectors shall be as prescribed by the General Corporation Law and shall include: determining the number of shares outstanding and the voting power of each; the shares represented at the meeting; the existence of a quorum; the authenticity, validity and effect of proxies; receiving votes, ballots or consents; hearing and determining all challenges and questions in any way arising in connection with the right to vote; counting and tabulating all votes or consents; determining when the polls shall close; determining the result; and such acts as may be proper to conduct the election or vote with fairness to all

7

shareholders. In the determination of the validity and effect of proxies, the dates contained on the forms of proxy shall presumptively determine the order of execution of the proxies, regardless of the postmark dates on the envelopes in which they are mailed. The inspectors of election shall perform their duties impartially, in good faith, to the best of their ability and as expeditiously as is practical. If there are three (3) inspectors of election, the decision, act or certificate of a majority is effective in all respects as the decision, act or certificate of all. Any report or certificate made by the inspectors of election is prima facie evidence of the facts stated therein.

ARTICLE III

Fourth - To authorize the issue of shares of stock for the Corporation from time to time, upon such terms as may be lawful.

Fifth - To borrow money and incur indebtedness for the purposes of the Corporation, and to cause to be executed and delivered therefor, in the corporate name, promissory notes, bonds, capital notes, debentures, deeds of trust, mortgages, pledges, hypothecations or other evidences of debt and securities therefor, to the extent permitted by law.

The exact number of directors shall be seven (7) until changed as provided in this Section 3.2.

Section 3.3 ELECTION AND TERM OF OFFICE. Each director, including a director elected to fill a vacancy, shall hold office until the expiration of the term for which he is elected and until a successor has been elected and qualified.

(c) The shareholders may elect a director at any time to fill any vacancy not filled by the directors.

Section 3.5 REMOVAL.

(b) Any or all of the directors may be removed without cause if such removal is approved by a majority of the outstanding shares entitled to vote; provided, however, that no director may be removed if the votes cast against removal of the director, or not consenting in writing to the removal, would be sufficient to elect the director if voted cumulatively (without regard to whether shares may otherwise be voted cumulatively) at an election at which the same total number of votes were cast (or, if the action is taken by written consent, all shares entitled to vote were voted) and either the number of directors elected at the most recent annual meeting of shareholders, or if greater, the number of directors for whom removal is being sought, were then being elected.

Any director may resign effective upon giving written notice to the Chairman of the Board, the President, the Secretary or the Board of Directors of the Corporation, unless the notice specifies a later time for the effectiveness of such resignation. If the resignation is effective at a future time, a successor may be elected to take office when the resignation becomes effective.

Section 3.7 FEES AND COMPENSATION. Directors may be paid for their services in such capacity a sum in such amounts, at such times and upon such conditions as may be determined from time to time by resolution of the Board of Directors and may be reimbursed for their expenses, if any, for attendance at each meeting of the Board. No such payments shall preclude any director from serving the Corporation in any other capacity and receiving compensation in any manner therefor.

Section 3.8 INDEMNIFICATION OF CORPORATE AGENTS. The Corporation may indemnify each of its agents against expenses, judgments, fines, settlements and other amounts, actually and reasonably incurred by such person having been made or having been threatened to be made a party to a proceeding to the fullest extent possible by the provisions of the General Corporation Law and the Corporation may advance the expenses reasonably expected to be incurred by such agent in defending any such proceeding upon receipt of the undertaking required by the General Corporation Law.

No contract or other transaction between the Corporation and one or more of its directors, or between the Corporation and any corporation, firm or association in which one or more of its directors has a material financial interest (a mere common directorship shall not constitute a material financial interest), is either void or voidable because such director or directors or such other corporation, firm or association are parties or because such director or directors are present at the meeting of the board or a committee thereof which authorizes, approves or ratifies the contract or transaction, if:

(i) the material facts as to the transaction and as to such director’s interest are fully disclosed or known to the shareholders, and such contract or transaction is approved in good faith by the affirmative 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 shareholders, with the shares owned by the interested director or directors not being entitled to vote thereon; or

(b) Corporations Having Interrelated Directors. No contract or other transaction between the Corporation and any corporation or association of which one or more of its directors are directors is either void or voidable because such director or directors are present at the meeting of the Board or a committee thereof which authorizes, approves or ratifies the contract or transaction, if:

(i) The material facts as to the transaction and as to such director’s other directorship are fully disclosed or known to the Board or committee, and the Board or committee authorizes, approves or ratifies the contract or transaction in good faith by a vote sufficient without counting the vote of the common director or directors, or the contract or transaction is approved by the shareholders in good faith; or

In case such notice is delivered, personally or by telephone or other electronic means, as provided above, it shall be so delivered at least twenty four (24) hours prior to the time of the holding of the meeting. Such mailing or delivery, personally or by telephone or other electronic means, as provided above, shall constitute due, legal and personal notice to such director. Any notice shall state the date, place and hour of the meeting but need not state the purpose of the meeting.

Section 5.4 ACTION WITHOUT MEETING. Any action 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 such action. Such written consent or consents shall be filed with the minutes of the proceedings of the Board and shall have the same force and effect as a unanimous vote of such directors.

Section 5.5 ACTION AT A MEETING; QUORUM AND REQUIRED VOTE. A majority of the authorized number of directors then holding office constitutes a quorum of the Board for the transaction of business. Members of the Board may participate in a meeting through use of conference telephone, electronic video screen communication, or similar communications equipment, so long as all members participating in such meeting can hear one another. Participation in a meeting as permitted in the preceding sentence constitutes presence in person at such meeting. 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, unless a greater number, or the same number after disqualifying one or more directors from voting, is required by law, by the Articles of Incorporation, or by these Bylaws. A meeting at which a quorum is initially present may continue to transact business notwithstanding the withdrawal of a director, provided that any action taken is approved by at least a majority of the required quorum for such meeting.

Section 5.6 VALIDATION OF DEFECTIVELY CALLED OR NOTICED MEETINGS. 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, has prior to the meeting or at its commencement, protested the lack of proper notice to him, signs a written waiver of notice or a consent to holding such meeting or an approval of the minutes thereof. All such waivers, consents or approvals shall be filed with the corporate records or made a part of the minutes of the meeting.

Section 5.7 WAIVER OF NOTICE BY ATTENDANCE. Attendance by a director at any meeting shall constitute a waiver of notice of such meeting, unless a director attends for the express purpose of objecting to the transaction of any business because the meeting is not lawfully called, noticed, or convened; provided, however, if after stating his objection, the objecting director continues to attend and by his attendance participates in any matters other than those to which he objected, he shall be deemed to have waived notice of such meeting and withdrawn his objections.

13

Section 5.8 ADJOURNMENT. A majority of the directors present, whether or not a quorum is present, may adjourn any meeting to another time and place.

Section 5.9 NOTICE OF ADJOURNMENT. If the meeting is adjourned for more than twenty-four (24) hours, notice of any adjournment to another time or place shall be given prior to the time of the adjourned meeting to the directors who were not present at the time of adjournment.

GENERAL CORPORATE MATTERS

Section 8.1 RECORD DATE. The Board of Directors may fix a time in the future as a record date for the determination of the shareholders entitled to notice of and to vote at any meeting of shareholders or entitled to give consent to corporate action in writing without a meeting, to receive any report, to receive any dividend or distribution or any allotment of rights, or to exercise rights in respect to any change, conversion, or exchange of shares. The record date so fixed shall be not more than sixty (60) days nor less than ten (10) days prior to the date of any meeting, nor more than sixty (60) days prior to any other event for the purposes of which it is fixed. When a record date is so fixed, only shareholders of record on that date are entitled to notice of and to vote at any such meeting, to give consent to action without a meeting, to receive any report, to receive a 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, except as otherwise provided in the Articles of Incorporation or these Bylaws.

However, any contract or other instrument in writing executed or entered into between the Corporation and any other person, when signed by (i) the Chairman of the Board, the President or any Vice President, and (ii) the Secretary, any Assistant Secretary, the Chief Financial Officer or any Assistant Treasurer, is not invalidated as to the corporation by any lack of authority of the signing officers in the absence of actual knowledge on the part of the other person that the signing officers had no authority to execute such contract or other instrument.

Section 8.4 ISSUANCE AND RECORDATION OF SHARES.

(a) Certificates for Shares. Except as provided in subsection (b) below, every holder of shares in the Corporation shall be entitled to have a certificate signed in the name of the Corporation by the Chairman of the Board, Vice Chairman of the Board, President or a Vice President; and by the Chief Financial Officer or an Assistant Treasurer or the Secretary or any Assistant Secretary;

18

certifying the number of shares and the class or series of shares owned by the shareholder. Any of the signatures on the certificate may be a facsimile. In case any officer, transfer agent or registrar who has signed or whose facsimile signature has been placed upon a certificate shall have ceased to be such officer, transfer agent or registrar before such certificate is issued, it may be issued by the Corporation with the same effect as if such person were an officer, transfer agent or registrar at the date of issue.

(b) Electronic Issuance and Recordation. Notwithstanding subsection (a) above, the Corporation may adopt a system of issuance, recordation and transfer of its shares by electronic or other means not involving any issuance of certificates, including provisions for notice to purchasers in substitution for the required statements on certificates as set forth in Section 8.5 below, which system (i) has been approved by the United States Securities and Exchange Commission, (ii) is authorized in any statute of the United States, or (iii) is in accordance with Division 8 (commencing with Section 8101) of the California Commercial Code. Any system so adopted shall not become effective as to issued and outstanding certificated securities until the certificates therefor have been surrendered to the Corporation.

Section 8.5 STATEMENTS ON CERTIFICATE FOR SHARES. Any certificates issued in accordance with Section 8.4(a) above shall also contain such legend or other statement as may be required by law, by these Bylaws or by any agreement between the Corporation and the issuee thereof.

Section 8.6 LOST, STOLEN OR DESTROYED CERTIFICATES. No new certificates for shares shall be issued to replace an old certificate unless the latter is surrendered and cancelled at the same time; provided, however, that the Board of Directors, the Chairman of the Board or the President may, in case any certificate for shares is lost, stolen, mutilated or destroyed, authorize the issuance of a new certificate in lieu thereof, upon such terms and conditions, including reasonable indemnification of the Corporation, as the Board of Directors, the Chairman of the Board or the President shall determine. In the event of the issuance of a new certificate, the rights and liabilities of the Corporation, and of the holders of the old and new certificates, shall be governed by the relevant provisions of the California Commercial Code.

Section 8.7 REPRESENTATION OF SHARES OF OTHER CORPORATIONS. Any person designated by resolution of the Board of Directors or, in the absence of such designation, the Chairman of the Board, the President or any Vice President or the Secretary, or any other person authorized by any of the foregoing, is authorized to vote on behalf of the Corporation any and all shares of any other corporation or corporations, foreign or domestic, owned by the Corporation.
