ARTICLE I - OFFICES ------- 1.01 - PRINCIPAL OFFICE ---------------- The principal executive and business office of the corporation is hereby fixed and located in the County of Contra Costa, State of California or such other location as the board of directors may determine. 1.02 - OTHER OFFICES ------------- Branch or subordinate offices may at any time be established at any place or places by the board of directors. ARTICLE II - MEETINGS OF SHAREHOLDERS ------------------------ 2.01 - PLACE OF MEETINGS ----------------- All annual and all other meetings of shareholders shall be held at the principal executive office of the corporation, or at any other place within or without the State of California which may be designated either by the board of directors, or by the written consent of all shareholders entitled to vote thereat, provided such shareholder consent is given either before or after the meeting and filed with the secretary of the corporation. 2.02 - ANNUAL MEETINGS --------------- The annual meetings of shareholders shall be held on the first Thursday of the fourth month following the end of each fiscal year at 10:00 a.m.; provided, however, that should said day fall upon a legal holiday, then any such annual meeting of shareholders shall be held at the same time and place on the next day thereafter ensuing which is not a legal holiday. At such meetings, 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. 2.03 - SPECIAL MEETINGS ---------------- Special meetings of the shareholders, for any purpose or purposes whatsoever, may be called at any time by any of (i) the president, (ii) the board of directors, (iii) the chairman of the board, or (iv) one or more shareholders holding shares in the aggregate entitled to cast not less than 10 percent of the votes at that meeting. If a special meeting is called by any person or persons other than the board of directors, such person shall make a request therefor in writing, specifying (i) the date and time of such meeting, which shall be not less than 35 nor more than 60 days after the receipt of the request, and (ii) the general nature of the business proposed to be transacted at the meeting. Such request shall be delivered personally or sent by registered mail or by telegraphic or other facsimile transmission to the chairman of -2- the board, the president, any vice president or the secretary of the corporation. The officer receiving the request shall cause notice to be given within 20 days to the shareholders entitled to vote, in accordance with the provisions of Sections 2.4 and 2.5, and the notice shall set forth that a meeting will be held at the time requested by the person or persons calling the meeting. If the notice is not given within such 20-day period, the person(s) requesting the meeting may give the notice. 2.04 - NOTICE OF MEETINGS ------------------ All notices of meetings of shareholders, whether annual or special, shall be sent or otherwise given not less than 10 nor more than 60 days before the date of the meeting, except as provided in Section 2.03. 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 the 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. The notice shall also state the general nature of the proposal if action is proposed to be taken at any meeting for approval of any of the following: (i) a contract or transaction in which a director has a direct or indirect financial interest; -3- (ii) an amendment of the articles of incorporation; (iii) a reorganization of the corporation; (iv) a voluntary dissolution of the corporation; or (v) a distribution in dissolution other than in accordance with the rights of any outstanding preferred shares. Notwithstanding the absence of specific notice thereof, any such action may nevertheless be presented to the meeting and be validly acted upon by the shareholders if approved by all shareholders entitled to vote thereon, unless they sign waivers of notice specifying the general nature of the proposal so approved. 2.05 - MANNER OF GIVING NOTICE; AFFIDAVIT OF NOTICE -------------------------------------------- Notice of any shareholders' meeting shall be given either personally or by first-class mail or telegraphic or 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 has been so given, notice shall be deemed to have been given if published at least once in a newspaper of general circulation in the county where that office is located or in any manner permitted by law. Notice shall be deemed to have been given at the time when delivered personally, deposited in the mail, delivered to a common carrier for transmission to the recipient, actually transmitted by electronic means to the recipient by the -4- person giving the notice, or sent by other means of written communication. An affidavit of the mailing or other means of giving any notice of any shareholders' meeting may be executed by the secretary, assistant secretary, or any transfer agent of the corporation giving the notice, and filed and maintained in the minute book of the corporation. 2.06 - ADJOURNED MEETINGS 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 the majority of the shares which are represented at the meeting either in person or by proxy, but in the absence of a quorum. It shall not be necessary to give any notice of an adjournment or of the business to be transacted at an adjourned meeting other than by announcement at the meeting at which such adjournment is taken. However, when any shareholders' meeting, either annual or special, is adjourned for more than 45 days, or if after the adjournment a new record date is fixed for the adjourned meeting notice of the adjourned meeting shall be given to each shareholder of record entitled to vote at the adjourned meeting. At any adjourned meetings, the corporation may transact any business that might have been transacted at the regular meeting. 2.07 - RECORD DATE FOR SHAREHOLDERS OF RECORD -------------------------------------- -5- For purposes of determining which shareholders are entitled to receive notice of any meeting, to vote, or to give consent to corporate action without a meeting, the board of directors may fix a record date in advance of such meeting or corporate action which shall not be less than l0 nor more than 60 days before any such meeting or any such action without a meeting. Only shareholders of record at the close of business on the date so fixed are entitled to notice and to vote or to give consent, 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, by agreement, or 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 receive 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; and (b) The re cord 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 -6- close of business on the day on which the board adopts the resolution relating to that action, or the 60th day before the date of such other action, whichever is later. 2.08 - VOTING AT MEETINGS ------------------ Except as otherwise provided in the articles of incorporation and in the case of cumulative voting for directors, each shareholder is entitled to one vote per share. 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 the election 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. The affirmative vote of a majority of the shares represented and voting, provided such shares voting affirmatively 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 California General Corporation Law or by the articles of incorporation. -7- Every shareholder entitled to vote at any election for directors shall have the right to cumulate his votes by (i) giving one candidate a number of votes equal to the number of directors to be elected multiplied by the number of votes to which his shares are entitled, or (ii) distributing such cumulated votes on the same principle among as many candidates as he chooses; provided that the name of such candidate has been placed in nomination prior to the voting and that at least one shareholder has given notice at the meeting, prior to the voting, of an intention to cumulate votes. In any election of directors, the candidates receiving the highest number of votes, up to the number of directors to be elected, shall be elected. Votes against a director or not cast shall have no effect. 2.09 - QUORUM ------ The presence in person or by proxy of persons entitled to vote a majority of the voting shares at any meeting shall constitute a quorum of the shareholders 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 one or more 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. 2.10 - CONSENT OF ABSENTEES -------------------- -8- The transactions of any meeting of shareholders, either annual or special, however called and noticed and wherever held, shall be as valid as though made at a meeting duly held after regular call and notice if a quorum is present either in person or by proxy and if, either before or after the meeting, each of the shareholders entitled to vote who was not present in person or by proxy signs a written waiver of notice or a consent to the holding of such meeting or an approval of the minutes thereof. 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, unless the action taken or proposed to be taken is for approval of any of those matters specified in Section 2.04. All such waivers, consents or approvals shall be filed with the corporate records or made a part of the minutes of the meeting. Attendance at a meeting, in person or by proxy, shall also constitute a waiver of notice of that meeting, except when the person objects at the beginning of the meeting to the transaction of any business because the meeting has not been 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 required by law to be included in the notice of the meeting but not so included, if that objection is expressly made at the meeting. 2.11 - ACTION WITHOUT MEETING ---------------------- -9- Except as may be limited by the articles of incorporation and except for the election of directors, any action which may be taken by vote of the shareholders at any annual or special meeting 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 such action at a meeting at which all shares entitled to vote thereon were present and voted. Directors may be elected by written consent without a meeting only if the written consents of all outstanding shares entitled to vote are obtained, except that a vacancy in the board (other than a vacancy created by removal of a director) not filled by the board may be filled by the written consent of the holders of a majority of the outstanding shares entitled to vote. All such consents shall be filed and maintained in the corporate records. Any shareholder (or the shareholder's proxyholders, or a transferee of the shares or a personal representative of the shareholder or their respective proxyholders) giving a written consent may revoke the consent only 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. Such revocation is effective upon its receipt by the secretary of the corporation. -10- Unless the consents of all shareholders entitled to vote have been solicited in writing: (1) Notice of shareholder approval without a meeting by less than unanimous written consent shall be given at least 10 calendar days before the consummation of the action authorized by such approval, if the corporate action concerns (i) a contract or transaction in which a director has a direct or indirect financial interest under Section 310 of the California Corporations Code, (ii) indemnification of agents of the corporation, (iii) reorganization of the corporation, or (iv) a distribution in dissolution other than in accordance with the rights of the outstanding preferred shares; and (2) Prompt notice shall be given of any other corporate action approved by shareholders without a meeting by less than unanimous written consent. All such notices shall be given in the manner provided by Section 2.05. 2.12 - 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 -11- 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 (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 attendance at the meeting and voting in person by the person executing the proxy, or by a subsequent proxy executed by the same person and presented at the meeting; 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 11 months from the date of the proxy, unless another term of longer or shorter duration is specified in the proxy. The revocability of a proxy that states on its face that is irrevocable shall be governed by the provisions of Sections 705(e) and 705(f) of the Corporations Code of California. ARTICLE III - DIRECTORS --------- 3.01 - POWERS ------ Except as reserved to the shareholders by law, the articles of incorporation or these bylaws, all corporate powers shall be exercised by or under the authority of, and the business and affairs of the corporation shall be controlled by, the board of -12- directors.

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, debentures, deeds of trust, mortgages, pledges, hypothecations or other evidences of debt and securities therefor. Sixth: To designate, by resolution adopted by a majority of the ------ authorized number of directors, 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 such committee shall have all the authority of the board to the extent provided in the resolution of the board or in the bylaws, except with respect to: (a) The approval of any action for which, under the General Corporation Law of California, also requires approval of the shareholders or approval of the outstanding shares; -14- (b) The filling of vacancies on the board or in any committee; (c) The fixing of compensation of the directors for serving on the board or on any committee; (d) The amendment or repeal of bylaws or the adoption of new bylaws; (e) The amendment or repeal of any resolution of the board which by its express terms is not so amendable or repeal-able; (f) A distribution to the shareholders of the corporation, except at a rate, in a periodic amount or within a price range set forth in the articles or determined by the board; or (g) The appointment of other committees of the board or the members thereof. Seventh: To declare dividends at such times and in such amounts as the -------- condition of the affairs of the corporation may warrant. Eighth: Generally to exercise all of the powers and to perform all of the ------- acts and duties that from time to time may be permitted by law appertaining to their office. 3.02 - NUMBER OF DIRECTORS ------------------- The authorized number of directors of the corporation shall be not less than five nor more than nine, with the exact number of -15- authorized directors to be fixed within the foregoing limits by the board of directors or by the shareholders. 3.03 - ELECTION AND TERM OF OFFICE --------------------------- The directors shall be elected at each annual meeting of shareholders and may be elected at any special meeting of shareholders held for that purpose. Each director shall hold office until his successor is elected and qualified, or until his earlier death, resignation, removal or ineligibility. 3.04 - REMOVAL ------- A director may be removed for cause by (i) the board, when such director has been convicted of a felony or declared incompetent by court order, or (ii) the superior court, at the suit of at least 10% of the shareholders of any class of shares having found that the director has either committed fraudulent or dishonest acts, or has grossly abused his authority with reference to the corporation. A director may be removed without cause by a majority vote of all outstanding shares, provided that (i) where cumulative voting is in effect, such director may not be removed over the objection of the number of shares required to elect him, and (ii) where the articles of incorporation provide for the election of a director by the shareholders of a certain class or series of shares, such -16- director may be removed only by the majority vote of the outstanding shares of such class or series. Except as provided in this Section 3.04, and any reduction of the authorized number of directors notwithstanding, a director may not be removed prior to the expiration of such director's term of office. 3.05 - VACANCIES --------- 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. A vacancy in the board of directors shall be deemed to exist (i) in case of the death, resignation, ineligibility or removal of any director, (ii) if the authorized number of directors is increased, or (iii) if the shareholders fail, at any annual or special meeting of shareholders at which any director or directors are elected, to elect the full authorized 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. In the event that such a vacancy is created by an event other than removal, any election by written consent of the shareholders must be signed by holders of a majority of the outstanding shares. If the board of directors accepts the resignation of a director tendered to take effect at a future time, the board or the -17- shareholders shall have the power to elect a successor to take office when the resignation is to become effective. 3.06 - MEETINGS BY TELEPHONE CONFERENCE -------------------------------- Members of the board may participate in a meeting through use of conference telephone or similar communication equipment, so long as all members participating in such meeting can hear one another. 3.07 - ACTION WITHOUT MEETING ---------------------- Any action required or permitted to be taken by the board of directors or any committee thereof may be taken without a meeting if each member of the board consents in writing to such action.

In case such notice is mailed, it shall be deposited in the United States mail at least four days prior to the date of the meeting. In case such notice is delivered personally or telegraphed, it shall be so delivered or deposited with the telegraph company at least 48 hours prior to the time of the meeting. 3.10 - ADJOURNMENT ----------- A majority of the directors present, whether or not a quorum is present, may adjourn any directors' meeting to another time and place. If a meeting is adjourned for more than 24 hours, notice of any adjournment to another time or place shall be given in the manner specified in Section 3.09 prior to the time of the adjourned meeting to the directors who were not present at the time of adjournment. 3.11 - WAIVER OF NOTICE ---------------- The transactions at any meeting of the board of directors, however called and noticed, or wherever held, shall be as valid as though such transactions had occurred 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 -19- signs a written waiver of notice of or consent to holding the 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. 3.12 - QUORUM ------ A majority of the authorized number of directors then holding office shall constitute a quorum for the transaction of business. The act of the majority of the directors at a meeting at which a quorum is present shall be the act of the board of directors, unless a greater number is required by law, the articles of incorporation or these bylaws. However, 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 such meeting. The provisions of this Section 3.12 shall apply to action taken by any committee from time to time designated by the board of directors. 3.13 - APPROVAL OF LOANS TO OFFICERS ----------------------------- The corporation may, upon the approval of the Board of Directors alone, make loans of money or property to, or guarantee the obligations of, any officer of the corporation or its parent or subsidiary, whether or not a director, or adopt an employee benefit plan or plans authorizing such loans or guarantees provided that -20- (i) no such loan to any one individual be in excess of $500,000 in the aggregate; (ii) loans made in any one year may not exceed $1,000,000; (iii) all such loans be approved by all outside directors (directors who are not directly employed by the Company); (iv) the Board of Directors determines that such a loan or guaranty or plan may reasonably be expected to benefit the corporation; (v) the corporation has outstanding shares held of record by 100 or more persons (determined as provided in Section 605 of the California Corporations Code) on the date of approval by the Board of Directors; and (vi) the approval of the Board of Directors is by vote sufficient without counting the vote of any interested Director or Directors.
