 7. Management. The management of the Company shall be exclusively vested in a
Board of Directors (the “Board”) and, subject to the direction of the Board, the officers (the “Officers”), who shall collectively (Board and Officers) constitute “managers” of the Company within the
meaning of the Act. The authority and functions of the Board on the one hand and of the Officers on the other shall be identical to the activity and functions of the board of directors and officers, respectively, of a corporation organized under the
Delaware General Corporation Law. Thus, the business and affairs of the Company shall be managed by the Board, and the day-to-day activities of the Company shall be conducted on the Company’s behalf by the Officers, who shall be agents of the
Company.

“Directors”) appointed by the Organizational Member, such number of Directors to be determined from time to time by the Organizational Member. Vacancies on the Board for whatever cause shall be filled by the remaining Directors or,
if there be none, by the Organizational Member. The Directors shall hold office until their respective successors are chosen and qualify or until their earlier death, resignation or until removed by the Organizational Member, in the Organizational
Member’s discretion. The Board may act (a) by majority vote of Directors present at a meeting at which a quorum (consisting of a majority of Directors) is present or (b) by unanimous written consent.

such committee, to the extent provided in the resolution of the Board or in this Agreement, shall have and may exercise all powers and authority of the Board in the management of the business and affairs of the Company; but no such committee shall
have the power or authority in reference to the following matters: 
 1.1.1 approving or adopting any action or
matter expressly required by this Agreement or the Delaware Act to be submitted to the Organizational Member for approval or adoption; or 

1.1.2 amending or repealing any provision of this Agreement. 

In connection with the appointment of any committee, the Board shall adopt a charter for the committee which shall be revised from time
to time in accordance with its terms. 
 Unless otherwise specified by resolution of the Board, any committee designated
pursuant to this subsection shall choose its own chairman, shall keep regular minutes of its proceedings and report the same to the Board when requested and shall fix its own rules or procedures and shall meet at such times and at such place or
places as may be provided by such rules. At every meeting of any such committee, the presence of a majority of all the members thereof shall constitute a quorum and the affirmative vote of a majority of the members present at a meeting of which a
quorum is present shall be necessary for the adoption by the committee of any resolution.

 The Board shall have power at any time to fill vacancies in, or to change the membership of,
any committee, or to dissolve any such committee. Nothing herein shall be deemed to prevent the Board from appointing one or more committees consisting in whole or in part of persons who are not Directors; provided, however, that no such committee
shall have or may exercise any authority of the Board. 
 10. Officers. The Board
shall have the power to appoint any individual or individuals as the Company’s Officers to act for the Company and to delegate to such Officers such of the powers as are granted to the Board hereunder. The Officers shall have such titles as the
Board shall deem appropriate. Unless the authority of an Officer is limited by the Board, any Officer so appointed shall have the same authority to act for the Company as a corresponding officer of a Delaware corporation would have to act for a
Delaware corporation in the absence of a specific delegation of authority. Any decision or act of an Officer within the scope of the Officer’s designated or delegated authority shall control and shall bind the Company (and any business entity
for which the Company exercises direct or indirect managerial authority). A Director may be an Officer. The Officers shall hold office until their respective successors are chosen and qualify or until their earlier death, resignation or removal. Any
Officer elected or appointed by the Board may be removed at any time by the Board. Any vacancy occurring in any office of the Company shall be filled by the Board. 

11. Dissolution. The Company shall dissolve and its affairs shall be wound up at such time, if any, as the
Board may elect. No other event will cause the Company to dissolve. 
 12. Governing Law.
THIS AGREEMENT IS GOVERNED BY AND SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE (EXCLUDING ITS CONFLICT-OF-LAWS RULES). 

13. Amendments. This Agreement may be modified, altered, supplemented or amended at any time by a written
agreement executed and delivered by the Organizational Member.
