4.2 Number. The number of directors may be either increased or decreased by resolution of the shareholders at their regular meetings or at a special meeting called for that purpose.

Notice of the meeting of the Board of Directors need not state the purpose of the meeting. A director may orally or in writing waive notice of the meeting. Attendance by a director at a meeting of the Board of Directors also constitutes a waiver of notice of such meeting, unless the director objects at the beginning of the meeting to the transaction of business because the meeting allegedly is not lawfully called or convened and such director does not participate thereafter in the meeting.

4.7 Meeting by Electronic Communications. A conference among directors by any means of communication through which the directors may simultaneously hear each other during the conference constitutes meeting of the Board of Directors if the number of directors participating in the conference would be sufficient to constitute a quorum at a meeting, and if the same notice is given of the conference as would be required for a Board of Directors meeting under these By-Laws. In any Board of Directors meeting, a director may participate by any means of communication through which the director, other directors so participating, and all directors physically present at the meeting may simultaneously hear each other during the meeting.

4.8 Compensation. Directors may receive such compensation as may be determined from time to time by resolution of the Board of Directors.

4.9 Committee. By the affirmative vote of a majority of the directors, the Board of Directors may establish a committee or committees having the authority of the Board of Directors in the management of the business of the Corporation to the extent provided in the resolution adopted by the Board of Directors. A committee shall consist of one or more persons, who need not be directors, that have been appointed by affirmative vote of a majority of the directors present.

Minutes of any meetings of committees created by the Board of Directors shall be available upon request to members of the committee and to any director.

4.10 Action by Absent Director. A director may give advance written consent or opposition to a proposal to be acted upon at a Board of Directors meeting by giving a written statement to the Chief Executive Officer, Chief Financial Officer, or any director which sets forth the proposal to be voted on and contains a statement of the director’s voting preference with regard to the proposal. An advance written statement does not constitute presence of the director for purposes of determining a quorum, but the advance written statement shall be counted in the vote on the subject proposal provided that the proposal acted on at the meeting is substantially the same or has substantially the same effect as the proposal set forth in the advance written statement. The advance written statement by a director on a proposal shall be included in the records of the Board of Directors’ action on the proposal.

4.11 Removal of Directors by Board of Directors. Any director who has been elected by the Board of Directors to fill a vacancy on the Board of Directors, or to fill a directorship created by action of the Board of Directors, and who has not subsequently been reelected by the shareholders, may be removed by a majority vote of all directors constituting the Board, exclusive of the director whose removal is proposed.

4.12 Vacancies. Any vacancy on the Board of Directors may be filled by vote of the remaining directors, even though less than a quorum.

4.13 Written Action by Less than All of the Directors.

If a written action is signed by less than all the directors, any director not signing the action will be notified as soon as reasonably possible of the content of the action and the effective date of the action. Failure to provide the notice does not invalidate the written action. A director who does not sign or consent to the written action has no liability for the action or actions so taken.

4.14 Dissent from Action. A director of the Corporation who is present at a meeting of the Board of Directors at which any action is taken shall be presumed to have assented to the action taken unless the director objects at the beginning of the meeting to the transaction of business because the meeting is not lawfully called or convened and does not participate thereafter, or unless the director votes against the action at the meeting, or is prohibited from voting on the action.

4.15 Disclosure to Gaming Regulatory Authorities.
