This Amendment No. 1 is entered with reference to the following facts:

1. The Company was organized on January 8, 2007, by the filing of its articles of organization with the office of the Nevada Secretary of State. The original members of the Company entered into that certain Operating Agreement, dated January 11, 2007 (the “Operating Agreement”). Except as otherwise defined in this Amendment, defined terms used shall have the meanings set forth in the Operating Agreement for such terms.

2. The Members hereby amend the Operating Agreement by the revision of Article VII, Management, as follows:

ARTICLE VII

MANAGEMENT

7.1 Managers Board.

(a) The management of the Company shall be vested in the Board of Managers (the “Board”) designated by the Members. The Operating Manager, who shall be appointed by the Board from among its Managers, shall report to and be subject to the direction of the Board. The initial Operating Manager of the Company shall be Thomas Reeg.

(b) The number of Managers on the Board shall be four (4) unless otherwise provided herein. The initial Managers of the Company shall be the following:

Thomas Reeg	Ryan Langdon
Timothy Janszen	Roger May

(c) A Manager shall remain in office until removed by action of the holders of a majority of membership units of the Company having voting authority.

(d) A Manager (including the Operating Manager) may be removed from the position of Manager at any time, with or without cause, by the written notice of

1

the holders of a majority of the membership units of the Company having voting authority. Any removal of the Operating Manager from the position of Manager pursuant to this Section 7.1(d) shall also constitute the removal of such Manager from the position of Operating Manager without the necessity of any further action pursuant to Section 7.8.

(e) In the event any Manager dies or is unwilling or unable to serve as such or is removed from office, the remaining Managers shall promptly designate a successor to such Manager.

(f) Each Manager shall have one (1) vote. Except as otherwise provided in this Agreement, the Board shall act by the affirmative vote of a majority of the total number of members of the Board.

(g) Each Manager shall perform his duties as a Manager in good faith, in a manner he reasonably believes to be in the best interests of the Company, and with such care as an ordinarily prudent person in a like position would use under similar circumstances. A person who so performs his duties shall not have any liability by reason of being or having been a Manager of the Company.

(h) The Board shall have the power to delegate authority to the Operating Manager by express written delegation as it may from time to time deem appropriate. Any delegation of authority to take any action must be approved in the same manner as would be required for the Board to approve such action directly.

(i) A Manager shall not be liable under a judgment, decree or order of court, or in any other manner, for a debt, obligation or liability of the Company.

7.2 Meetings of the Board.

(a) The Board shall hold regular meetings no less frequently than once every year and shall establish meeting times, dates and places and requisite notice requirements and adopt rules or procedures consistent with the terms of this Agreement. Unless otherwise approved by the Board, each regular meeting of the Board will be held at the Company’s principal place of business and attendance by the Operating Manager is mandatory. At such meetings the Board shall transact such business as may properly be brought before the meeting, whether or not notice of such meeting referenced the action taken at such meeting.

(b) Special meetings of the Board may be called by any Manager. Notice of each such meeting shall be given to each Manager on the Board by telephone, telecopy, telegram or similar method (in each case, notice shall be given at least

2

twenty-four (24) hours before the time of the meeting) or sent by first-class mail (in which case notice shall be given at least three (3) days before the meeting), unless a longer notice period is established by the Board. Each such notice shall state (i) the time, date, place (which shall be at the principal office of the Company unless otherwise agreed to by all Managers) or other means of conducting such meeting and (ii) the purpose of the meeting to be so held. No actions other than those specified in the notice may be considered at any special meeting unless unanimously approved by the Managers. Any Manager may waive notice of any meeting in writing before, at, or after such meeting. The attendance of a Manager at a meeting shall constitute a waiver of notice of such meeting, except when a Manager attends a meeting for the express purpose of objecting to the transaction of any business because the meeting was not properly called.

(c) Any action required to be taken at a meeting of the Board, or any action that may be taken at a meeting of the Board, may be taken at a meeting held by means of conference telephone or other communications equipment by means of which all persons participating in the meeting can hear each other. Participation in such a meeting shall constitute presence in person at such meeting.

(d) Notwithstanding anything to the contrary in this Section 7.2, the Board may take without a meeting any action that may be taken by the Board under this Agreement if such action is approved by the unanimous written consent of the Managers.

7.3 Board Powers.

(a) Except as otherwise provided in this Agreement or delegated to the Operating Manager hereunder, all powers to control and manage the affairs of the Company shall be exclusively vested in the Board and the Board may exercise all powers of the Company and do all such lawful acts as are not by statute, the Articles or this Agreement directed or required to be exercised or done by the Members and in so doing shall have the right and authority to take all actions which the Board deems necessary, useful or appropriate for the management and conduct of the Company’s business.

(b) The Board may appoint the officers of the Company and will establish policies and guidelines for the hiring of employees, as appropriate and necessary.

7.8 Replacement of Operating Manager.

In the event a majority of the Board shall at any time, or from time to time, be dissatisfied with the Operating Manager’s performance (regardless of whether such dissatisfaction shall constitute legal “cause” for termination) or believe removal of the Operating Manager is appropriate for any other reason, such Managers shall have the right to remove the Operating Manager from the position as Operating Manager (but not from the position as a member of the Board) upon written notice of such action to the Operating Manager. A person who is removed from the position of Operating Manager pursuant to this Section 7.8 shall continue to be a Manager until such person is removed from the position of Manager in accordance with Section 7.1 or otherwise ceases to be a Manager in accordance with the terms of this Agreement.

Such expenses shall not include any expenses incurred in connection with a Member’s or Managers’ exercise of its rights as a Member or a Manager apart from the authorized conduct of the Company’s business. The Board’s sole determination of which expenses are allocated to and reimbursed as a result of the Company’s activities or business and the amount of such expenses shall be conclusive. Such reimbursement shall be treated as expenses of the Company and shall not be deemed to constitute distributions to any Member of profit, loss or capital of the Company.

7.10 Compensation; Expenses and Loans.

(a) Compensation and Reimbursement. Except as otherwise provided in this Agreement, no Member or Affiliate of any Member shall receive any salary, fee, or draw for services rendered to or on behalf of the Company or otherwise in its capacity as a Member, nor shall any Member or Affiliate of any Member be reimbursed for any expenses incurred by such Member or Affiliate on behalf of the Company or otherwise in its capacity as a Member.

(d) Notwithstanding the provisions of Sections 7.11(a), 7.11(b) and 7.11(c) above, such Sections shall be enforced only to the maximum extent permitted by law and no Manager shall be indemnified from any liability for the fraud, intentional misconduct, gross negligence or a knowing violation of the law which was material to the cause of action.

(e) The obligations of the Company set forth in this Section 7.11 are expressly intended to create third party beneficiary rights of each of the Managers and any Member is authorized, on behalf of the Company, to give written confirmation to any Manager of the existence and extent of the Company’s obligations to such Manager hereunder.
