At all times during which GSO and/or its Affiliates collectively own at least $200 million of Class A Preferred Units (calculated with reference to the Class A Issue Price, as adjusted in accordance with the Partnership Agreement), then GSO will be entitled to appoint a Class A Board Observer to the Board of Directors, exercisable by the delivery of written notice to the Genesis Entities.

Except as provided below, the Class A Board Observers shall receive written notice of all meetings (both regular and special) of the Board of Directors at the same time and in the same manner as such notice is given to other members of the Board of Directors, and shall receive all documents, notices, minutes, written materials and other information given to members of the Board of Directors in connection with each Board of Directors meeting (collectively, “Materials”) at the same time such Materials are given to members of the Board of Directors, whether or not the Class A Board Observer is attending such meeting; provided, however, that no Class A Board Observer shall have the right to attend any meeting of, or receive any Materials with respect to, any committee of the full Board of Directors (each, a “Committee”); provided, further, however, the Genesis Entities shall (i) give the Class A Board Observers written notice of the applicable meeting or action taken by written consent of such Committee at the same time and in the same manner as notice is given to the members of such Committee and (ii) with respect to the Audit Committee and the Governance, Compensation and Business Development Committee of the Board of Directors, provide the Class A Board Observer with copies of all written materials and other information (including, without limitation, copies of minutes of meetings or written consents of such Committees) given to the members of such Committees in connection with such meetings or actions taken by written consent at the same time such materials and information are furnished to such members of such Committees.

(c) Notwithstanding anything to the contrary in this Section 2.01, each of KKR and GSO agree that the Class A Board Observers may be excluded from such portions of any Board of Directors meeting and that Materials may be withheld from the Class A Board Observers, in each case, as and solely to the extent the Board of Directors reasonably determines, in good faith, based on the advice of counsel, that such exclusion or withholding (A) is necessary to avoid any conflict of interest with respect to any potential transaction or matter related to the Genesis Entities or their Affiliates, on the one hand, and such Investor, such Class A Board Observer or any of their respective Affiliates or portfolio companies, on the other hand or (B) would prevent the members of the Board of Directors from engaging in attorney-client privileged communication; provided that, before the Genesis Entities may exclude a Class A Board Observer from any portion of any Board of Directors meeting or withhold from a Class A Board Observer any Materials pursuant to the foregoing provisions of this Section 2.01(c), the Genesis Entities shall notify the Class A Board Observer of its determination to do so, and consult with the Class A Board Observer to minimize or eliminate the need for such exclusion or withholding;

(d) Each Class A Board Observer shall agree to maintain the confidentiality of all material non-public information and proceedings of the Board of Directors and to enter into a customary confidentiality agreement (“Confidentiality Agreement”) as may be reasonably requested by the Genesis Entities; provided, however, the Genesis Entities acknowledge that upon request from an Investor or such Investor’s Affiliates, the Class A Board Observer shall provide, on a confidential basis, such material non-public information to such Investor and its Affiliates and their respective representatives, advisors and prospective transferees who have confirmed to the Investor their agreement to be bound by the confidentiality and use provisions of the Confidentiality Agreement.

None of the Class A Board Observer, the Investors or their respective Affiliates shall be obligated to present any investment opportunity to the Genesis Entities even if such opportunity is of a character that the Genesis Entities or any of their respective subsidiaries might reasonably be deemed to have pursued or had the ability or desire to pursue if granted the opportunity to do so, and each of the Class A Board Observer, the Investors or their respective Affiliates shall have the right to take for such person’s own account (individually or as a partner or fiduciary) or to recommend to others any such investment opportunity. Notwithstanding the foregoing, the Class A Board Observer shall be subject to, and comply with, the requirement to maintain confidential information pursuant to this Agreement.
