Section 4. Record Date: In order that the corporation may determine the stockholders entitled to notice of or to vote at any meeting of stockholders or any adjournment thereof, or to express consent to corporate action in writing without a meeting, or 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 change, conversion or exchange of stock or for the purpose of any other lawful action, the Board of Directors may fix, in advance, a record date, which shall not be more than sixty nor less than ten days before the date of such meeting, nor more than sixty days prior to any other action.

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

(b) The record date for determining stockholders entitled to express consent to corporate action in writing without a meeting, when no prior action by the Board of Directors is necessary, shall be the day on which the first written consent is expressed.

(c) The record date for determining stockholders for any other purpose shall be at the close of business on the day on which the Board of Directors adopts the resolution relating thereto.

Section 3. Notice: Whenever written notice is required to be given to any person, it may be given to such person, either personally or by sending a copy thereof through the mail, or by telegram, charges prepaid, to his or her address appearing on the books of the corporation, or supplied by him to the corporation for the purpose of notice. If the notice is sent by mail or by telegraph, it shall be deemed to have been given to the person entitled thereto when deposited in the United States mail or with a telegraph office for transmission to such person. Such notice shall specify the place, day and hour of the meeting and, in the case of a special meeting of stockholders, the general nature of the business to be transacted.

Waiver of Notice: Whenever any written notice is required by statute, or by the certificate or by the Bylaws of this corporation a waiver thereof in writing, signed by the person or persons entitled to such notice, whether before or after the time stated therein, shall be deemed equivalent to the giving of such notice. Except in the case of a special meeting of stockholders neither the business to be transacted at nor the purpose of the meeting need be specified in the waiver of notice of such meeting. Attendance of a person either in person or by proxy, at any meeting shall constitute a waiver of notice of such meeting except where a person attends a meeting for the express purpose of objecting to the transaction of any business because the meeting was not lawfully called or convened.

Disallowed Compensation: Any payments made to an officer or employee of the corporation such as a salary, commission, bonus, interest, rent, travel or entertainment expense incurred by him or her, which shall be disallowed in whole or in part as a deductible expense by the Internal Revenue Service, shall be reimbursed by such officer or employee to the corporation to the full extent of such disallowance. It shall be the duty of the directors, as a Board, to enforce payment of each such amount disallowed. In lieu of payment by the officers or employee, subject to the determination of the directors, proportionate amounts may be withheld from his or her future compensation payments until the amount owed to the corporation has been recovered.

Section 6. Resignations: Any director or other officer may resign at anytime, such resignation to be in writing, and to take effect from the time of its receipt by the corporation, unless such time is fixed in the resignation and then from that date. The acceptance of a resignation shall not be required to make it effective.

Section 7. Directors Held Harmless: Directors of the corporation shall not be liable to either the corporation or its stockholders for monetary damages for a breach of fiduciary duties unless the breach involves: (1) a director’s duty of loyalty to the corporation or its stockholders; (2) acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law; (3) liability for unlawful payments of dividends or unlawful stock purchases or redemption by the corporation; or (4) a transaction from which the director derived an improper personal benefit. Notwithstanding any of the foregoing, the directors reserve the right to adopt separate indemnification agreements for each officer and/or director which will not be construed to supersede any of the foregoing.

Section 1. The President and Board of Directors shall present at each annual meeting a full and complete statement of the business and affairs of the corporation for the preceding year. Such statement shall be prepared and presented in whatever manner the Board of Directors shall deem advisable and need not be verified by a certified public accountant.
