The procedure provided by statute shall apply to such application and any order issued by the court, including any order designating the time and place of the meeting, the record date for determination of Shareholders entitled to vote, and the form of notice.

Section 2.07. QUORUM. The presence in person or by proxy of the persons entitled to vote a majority of the voting shares at any meeting shall constitute a quorum for the transaction of business.

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, except as provided in Section 2.07, no other business may be transacted at such meeting.

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,

a notice of the adjourned meeting shall be given to each Shareholder of record entitled to vote at the meeting. Except as herein provided, notice need not be given of the adjourned meeting if the time and the place thereof are announced at the meeting at which the adjournment is taken.

Section 2.09. VOTING. Unless a record date for voting purposes is fixed as provided in these bylaws then, subject to the provisions of the California General Corporation Law, only persons in whose names shares entitled to vote stand on the stock records of the corporation on the day three days prior to any meeting of Shareholders shall be entitled to vote at such meeting. Such vote may be a viva voce or by ballot; provided, however, that all elections for Directors must be by ballot upon demand made by a Shareholder at any election and before the voting begins. Every Shareholder entitled to vote at an election for Directors shall have the right to cumulate his votes and give one candidate a number of votes equal to the number of Directors to be elected multiplied by the number of votes to which his shares are entitled, or to distribute his votes on the same principle among as many candidates as he shall desire. The candidates receiving the highest number of votes up to the number of Directors to be elected shall be elected.

Section 2.10. WAIVER OF NOTICE. The transactions of any meeting of Shareholders, however called and noticed, and wherever held, are as valid as though had 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 persons entitled to vote, not present in person or by proxy, signs a written waiver of notice or a consent to the holding of the meeting or an approval of the minutes thereof. All such waivers, consents and approvals shall be filed with the corporate records or made a part of the minutes of the meeting. Attendance of a person at a meeting shall constitute a waiver of notice of such 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 if such objection is expressly made at the meeting. Neither the business to be transacted at nor the purpose of any regular or special meeting of shareholders need be specified in any written waiver of notice, except as otherwise provided in these bylaws or by statute.

Section 2.11. ACTION WITHOUT MEETING. Except as otherwise provided by statute, 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 actions so taken, shall be signed by the holders of outstanding shares having not less than the minimum number of votes that would be necessary to authorize to rake such action at a meeting at which all shares entitled to vote thereon were present and voted, and such consent in writing is filed with the Secretary of the corporation; provided that unless the consents of all Shareholders entitled to vote have been solicited in writing, notice of any Shareholder approval or of the taking of any corporate action approved by such consent in writing, shall be given to those Shareholders entitled to vote who have not consented in writing, as provided by statute.

Section 2.12. 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 an instrument revoking it or another duly executed proxy bearing a later date is filed with the Secretary of the corporation; provided that no such proxy shall be valid after the expiration of eleven months from the date of its execution, unless the person executing it specifies therein the length of time for which such proxy is to continue in force, which in no case shall exceed seven years from the date of its execution.

Section 2.13. INSPECTORS OF ELECTION. 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 be not so appointed, the chairman of any such meeting may, and on the request of any Shareholder or his proxy shall, make such appointment at the meeting. The number of inspectors shall be either one or three. If appointed at a meeting on the request of one or more Shareholders or proxies, the majority of shares present shall determine whether one or three inspectors are to be appointed. In case any person appointed as inspector fails to appear or fails or refused to act, the vacancy may be filled by appointment by the Board of Directors in advance of the meeting, or at the meeting by the chairman thereof.

The duties of such inspectors shall be as prescribed by the California General Corporations Law and shall include: determining the number of shares outstanding 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 the result; and such acts as may be proper to conduct the election or vote with fairness to all Shareholders.

The Shareholders may elect a Director at any time to fill any vacancy not filled by the Directors, provided that any election by written consent shall require the consent of a majority of the outstanding shares entitled to vote.

If, after the filling of any vacancy by the Directors, the Directors then in office who have been elected by the Shareholders shall constitute less than a majority of the Directors then in office, any holder or holders of an aggregate of 5 percent or more of the total number of shares at the time outstanding having the right to vote for such Directors may call a special meeting of Shareholders, or the Superior Court of the proper County, shall, upon application of such Shareholder or Shareholders, summarily order a special meeting of Shareholders, to be held to elect the entire Board.
