Section 5. Notice of Adjourned Meetings: When a meeting is adjourned to another place or time, it shall not be necessary to give any notice of the adjourned meeting if the place and time to which the meeting is adjourned are announced at the meeting at which the adjournment is taken, and at the adjourned meeting any business may be transacted that might have been transacted on the original date of the meeting. If, however, after the adjournment the Board of Directors fixes a new record date for the adjourned meeting, a notice of the adjourned meeting shall be given as provided in this section to each shareholder of record on the new record date entitled to vote at such meeting.

Section 6. Closing of Transfer Books and Fixing Record Date: For the Purpose of determining shareholders entitled to notice of or to vote at any meeting of shareholders or any adjournment thereof, or entitled to receive payment of any dividend, or in order to make a determination of shareholders for any other purpose, the Board of Directors may provide that the stock transfer books shall be closed for a stated period but not to exceed, in any case, sixty days. If the stock transfer books shall be closed for the purpose of determining shareholders entitled

to notice of or to vote at a meeting of shareholders, such books shall be closed for at least ten days immediately preceding such meeting.

In lieu of closing the stock transfer books, the Board of Directors may fix in advance a date as the record date for any determination of shareholders, such date in any case to be not more than sixty days and, in case of a meeting of shareholders, not less than ten days prior to the date on which the particular action requiring such determination of shareholders is to be taken.

If the stock transfer books are not closed and no record date is fixed for determination of shareholders entitled to notice or to vote at a meeting of shareholders; or shareholders entitled to receive payment of a dividend, the date on which notice of the meeting is mailed or the date on which the resolution of the Board of Directors declaring such dividend is adopted, as the case may be, shall be the record date for such determination of shareholders.

When a determination of shareholders entitled to vote at any meeting of shareholders has been made as provided in this section, such determination shall apply to any adjournment thereof, unless the Board of Directors fixes a new record date for the adjourned meeting.

Voting Record: The officers or agent having charge of the stock transfer books for shares of the corporation shall make, at least ten days before each meeting of the shareholders, a complete list of the shareholders entitled to vote at such meetings or any adjournment thereof, with the address of and the number and class and series, if any, of shares held by each.

The list shall also be produced and kept open at the time and place of the meeting and shall be subject to the inspection of any shareholder at any time during the meeting.

If the requirements of this section have not been substantially complied with, the meeting on demand of any shareholder in person or by proxy, shall be adjourned until the requirements are complied with. If no such demand is made, failure to comply with the requirements of this section shall not affect the validity of any action taken at such meeting.

When a specified item of business is required to be voted on by a class or series shall constitute a quorum for the transaction of such item of business by that class or series.

If a quorum is present, the affirmative vote of the majority of the shares represented at the meeting and entitled to vote on the subject matter shall be the act of the shareholders unless otherwise provided by law.

After a quorum has been established at a shareholders’ meeting, the subsequent withdrawal of shareholders, so as to reduce the number of shareholders entitled to vote at the meeting below the number required for a quorum, shall not affect the validity of any action taken at the meeting or any adjournment thereof.

Section 9. Voting of shares: Each shareholder entitled to vote in accordance with the terms and provisions of the Articles. of Incorporation and these Bylaws, shall be entitled to one vote for each share of stock owned by such shareholder. Upon the demand of any shareholder, the vote for directors shall be by ballot. All other requirements as to voting, voting trusts and shareholders’ agreements shall be in accordance with the laws of the State of

Section 10. Proxies: Every shareholder entitled to vote at a meeting of shareholders or to express consent or dissent without a meeting or a shareholders’ duly authorized attorney-in-fact, may authorize another person or persons to act for him by proxy.

Every proxy must be signed by the shareholder or his attorney-in-fact. No proxy shall be valid after the expiration of eleven months from the date thereof unless otherwise provided in the proxy. Every proxy shall be revocable at the pleasure of the shareholder executing it, except as otherwise by law.

The authority of the holder of a proxy to act shall not be revoked by the incompetence or death of the shareholder who executed the proxy unless, before the authority is exercised, written notice of an adjudication of such incompetence or of such death is received by the corporate officer responsible for maintaining the list of shareholders.

If a proxy for the same shares confers authority upon two or more persons and does not otherwise provide, a majority of them present at the meeting, or if only one is present then that one, may exercise all the powers conferred by the proxy; but if the proxy holders present at the meeting are equally divided as to the right and manner of voting in any particular case, the voting of such shares shall be prorated.

If a proxy expressly provides, any proxy holder may appoint in writing a substitute to act in his place.

Section 11. Action by Shareholders Without a Meeting: Any action required by law, these bylaws, or the Articles of Incorporation of this corporation to be taken at any annual or special meeting of shareholders of the corporation, or any action which may be taken at any or special meeting of such shareholders, may be taken without a meeting, without prior notice and without a vote, if consent in writing, setting forth the action so taken, shall be signed by the holders of outstanding stock 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. If any class of shares is entitled to vote thereon as a class, such written consent shall be required of the holders of a majority of the shares of each class of shares entitled to vote as a class thereon and of the total shares entitled to vote thereon.

Within ten days after obtaining such authorization by written consent, notice shall be given to those shareholders who have not consented in writing. The notice shall fairly summarize the material features of the authorized action and, if the action be a merger, consolidation or sale or exchange of assets for which dissenters rights are provided under this act, the notice shall contain a clear statement of the right of shareholders dissenting therefrom to be paid the fair value of their shares upon compliance with further provisions of this act regarding the rights of dissenting shareholders.
