If the Company does not have sufficient cash to pay its obligations, any Member that may agree to do so may, upon Special Approval, advance all or part of the needed funds for such obligation to or on behalf of the Company.

(b) Notwithstanding anything to the contrary in this Agreement, (i) the engaging in competitive activities by any Indemnitees, other than employees of the Company, in accordance with the provisions of this Section 6.8 is hereby approved by the Company and all Members, (ii) it shall be deemed not to be a breach of any fiduciary duty or any other obligation of any type whatsoever of any Indemnitee, other than officers or employees of the Company, for such Indemnitees to engage in such business interests and activities in preference to or to the exclusion of the Company and (iii) the Indemnitees, other than Officers or employees of the Company, shall have no obligation hereunder or as a result of any duty expressed or implied by Law to present business opportunities to the Company, MLP GP or the MLP.

(c) Each Member and each of its Affiliates may acquire additional Membership Interests and, except as otherwise provided in this Agreement, shall be entitled to exercise, at their option, all rights relating to such Membership Interests.

Section 6.9 Resolution of Conflicts of Interest; Standard of Conduct and Modification of Duties.

(a) Unless otherwise expressly provided in this Agreement, whenever a potential conflict of interest exists or arises between the Members or any of their Affiliates (other than the MLP or any Group Member), on the one hand, and the MLP or any Group Member, on the other hand, any resolution or course of action by the Board in respect of such conflict of interest shall be permitted and deemed approved by all Members, and shall not constitute a breach of this Agreement or of any agreement contemplated herein or therein, or of any duty stated or implied by law or equity, if the resolution or course of action in respect of such conflict of interest is (i) approved by Special Approval, (ii) approved by the vote of a majority of the Units excluding Units owned by the Members and their Affiliates, (iii) on terms no less favorable to the MLP or Group Member, as the case may be, than those generally being provided to or available from unrelated third parties or (iv) fair and reasonable to the MLP or Group Member, as the case may be, taking into account the totality of the relationships between the parties involved (including other transactions that may be particularly favorable or advantageous to the MLP or Group Member, as the case may be). The Board shall be authorized but not required in connection with its resolution of such conflict of interest to seek Special Approval of such resolution, and the Board may also adopt a resolution or course of action that has not received Special Approval. If Special Approval is not sought and the Board determines that the resolution or course of action taken with respect to a conflict of interest satisfies either of the standards set forth in clauses (iii) or (iv), then it shall be presumed that, in making its decision, the Board acted in good faith, and in any proceeding brought by any Member or by or on behalf of such Member or the MLP or Group Member, as the case may be, challenging such approval, the Person bringing or prosecuting such proceeding shall have the burden of overcoming such presumption.

(b) Whenever the Company makes a determination or takes or declines to take any other action, or any of its Affiliates causes it to do so, in its capacity as the general partner of the General Partner of the MLP as opposed to in its individual capacity, whether under this Agreement, or any other agreement contemplated hereby or otherwise, then unless another express standard is provided for in this Agreement, the Company, or such Affiliates causing it to do so, shall make such determination or take or decline to take such other action in good faith and shall not be subject to any other or different standards imposed by this Agreement, any other agreement contemplated hereby or under the Delaware Act or any other law, rule or regulation or at equity. In order for a determination or other action to be in “good faith” for purposes of any action taken or delivered to be taken by the Company in its capacity as the general partner of the General Partner of the MLP, the Person or Persons making such determination or taking or declining to take such other action must believe that the determination or other action is in the best interests of the MLP.

(c) Whenever the Company makes a determination or takes or declines to take any other action, or any of its Affiliates causes it to do so, in its individual capacity as opposed to in its capacity as a general partner of the General Partner of the MLP, whether under this

Agreement or any other agreement contemplated hereby or otherwise, then the Company, or such Affiliates causing it to do so, are entitled to make such determination or to take or decline to take such other action free of any fiduciary duty or obligation whatsoever to the MLP or any partner thereof, and the Company, or such Affiliates causing it to do so, shall not be required to act in good faith or pursuant to any other standard imposed by this Agreement, any other agreement contemplated hereby or under the Delaware Act or any other law, rule or regulation. By way of illustration and not of limitation, whenever the phrase, “at the option of the Company,” or some variation of that phrase, is used in this Agreement, it indicates that the Company is acting in its individual capacity. For the avoidance of doubt, whenever the Company votes or transfers its MLP Interests, or refrains from voting or transferring its MLP Interests, it shall be acting in its individual capacity.

(d) Notwithstanding anything to the contrary in this Agreement, the Company and its Affiliates shall have no duty or obligation, express or implied, to (i) sell or otherwise dispose of any asset of the MLP or any Group Member or (ii) permit the MLP or any Group Member to use any facilities or assets of the Company and its Affiliates, except as may be provided in contracts entered into from time to time specifically dealing with such use. Any determination by the Company or any of its Affiliates to enter into such contracts shall be at its option.

(e) Whenever a particular transaction, arrangement or resolution of a conflict of interest is required under this Agreement to be “fair and reasonable” to any Person, the fair and reasonable nature of such transaction, arrangement or resolution shall be considered in the context of all similar or related transactions.

DISSOLUTION, WINDING-UP AND TERMINATION

Section 9.1 Dissolution.

(a) Subject to compliance with Section 6.1(c), the Company shall dissolve and its affairs shall be wound up on the first to occur of the following events (each a “Dissolution Event”):

(i) the unanimous consent of the Board;

(ii) the entry of a decree of judicial dissolution of the Company under Section 18-802 of the Delaware Act; and

(iii) at any time there are no Members of the Company, unless the Company is continued in accordance with the Delaware Act or this Agreement.

(b) No other event shall cause a dissolution of the Company.

(c) Upon the occurrence of any event that causes there to be no Members of the Company, to the fullest extent permitted by law, the personal representative of the last remaining Member is hereby authorized to, and shall, within 90 days after the occurrence of the event that terminated the continued membership of such Member in the Company, agree in writing (i) to

continue the Company and (ii) to the admission of the personal representative or its nominee or designee, as the case may be, as a substitute Member of the Company, effective as of the occurrence of the event that terminated the continued membership of such Member in the Company.

(d) Notwithstanding any other provision of this Agreement, the Bankruptcy of a Member shall not cause such Member to cease to be a member of the Company, and, upon the occurrence of such an event, the Company shall continue without dissolution.

Section 9.2 Winding-Up and Termination.

(a) On the occurrence of a Dissolution Event, the Board shall select one or more Persons to act as liquidator. The liquidator shall proceed diligently to wind up the affairs of the Company and make final distributions as provided herein and in the Delaware Act. The costs of winding up shall be borne as a Company expense. Until final distribution, the liquidator shall continue to operate the Company properties with all of the power and authority of the Board. The steps to be accomplished by the liquidator are as follows:

(i) as promptly as possible after dissolution and again after final winding up, the liquidator shall cause a proper accounting to be made by a recognized firm of certified public accountants of the Company’s assets, liabilities, and operations through the last calendar day of the month in which the dissolution occurs or the final winding up is completed, as applicable;

(ii) the liquidator shall discharge from Company funds all of the debts, liabilities and obligations of the Company or otherwise make adequate provision for payment and discharge thereof (including the establishment of a cash escrow fund for contingent liabilities in such amount and for such term as the liquidator may reasonably determine); and

(iii) all remaining assets of the Company shall be distributed to the sole Member.

(b) The distribution of cash or property to a Member in accordance with the provisions of this Section 9.2 constitutes a complete return to the Member of its Capital Contributions and a complete distribution to the Member of its share of all the Company’s property and constitutes a compromise to which all Members have consented within the meaning of Section 18-502(b) of the Delaware Act. No Member shall be required to make any Capital Contribution to the Company to enable the Company to make the distributions described in this Section 9.2.

(c) On completion of such final distribution, the liquidator shall file a certificate of cancellation with the Secretary of State of the State of Delaware and take such other actions as may be necessary to terminate the existence of the Company.

ARTICLE XI.
GENERAL PROVISIONS

Section 11.1 Notices. Except as expressly set forth to the contrary in this Agreement, all notices, requests or consents provided for or permitted to be given under this Agreement must be in writing and must be delivered to the recipient in person, by courier or mail or by facsimile or other electronic transmission and a notice, request or consent given under this Agreement is effective on receipt by the Person to receive it; provided, however, that a facsimile or other electronic transmission that is transmitted after the normal business hours of the recipient shall be deemed effective on the next Business Day. All notices, requests and consents to be sent to a Member must be sent to or made at the addresses given for that Member as that Member may specify by notice to the other Members. Any notice, request or consent to the Company must be given to all of the Members. Whenever any notice is required to be given by applicable Law, the Organizational Certificate or this Agreement, a written waiver thereof, signed by the Person entitled to notice, whether before or after the time stated therein, shall be deemed equivalent to the giving of such notice. Whenever any notice is required to be given by Law, the Organizational Certificate or this Agreement, a written waiver thereof, signed by the Person entitled to notice, whether before or after the time stated therein, shall be deemed equivalent to the giving of such notice.

Section 11.2 Entire Agreement; Supersedure. This Agreement constitutes the entire agreement of the Members and their respective Affiliates relating to the subject matter hereof and supersedes all prior contracts or agreements with respect to such subject matter, whether oral or written.

Section 11.3 Effect of Waiver or Consent. Except as provided in this Agreement, a waiver or consent, express or implied, to or of any breach or default by any Person in the performance by that Person of its obligations with respect to the Company is not a consent or waiver to or of any other breach or default in the performance by that Person of the same or any other obligations of that Person with respect to the Company. Except as provided in this Agreement, failure on the part of a Person to complain of any act of any Person or to declare any Person in default with respect to the Company, irrespective of how long that failure continues, does not constitute a waiver by that Person of its rights with respect to that default until the applicable statute-of-limitations period has run.

Section 11.4 Amendment or Restatement. This Agreement may be amended or restated only by a written instrument executed by all Members; provided, however, that notwithstanding anything to the contrary contained in this Agreement, each Member agrees that the Board, without the approval of any Member, may amend any provision of the Organizational Certificate and this Agreement, and may authorize any Officer to execute, swear to, acknowledge, deliver, file and record any such amendment and whatever documents may be

required in connection therewith, to reflect any change that does not require consent or approval (or for which such consent or approval has been obtained) under this Agreement or does not materially adversely affect the rights of the Members.

Section 11.5 Binding Effect. This Agreement is binding on and shall inure to the benefit of the Members and their respective heirs, legal representatives, successors and assigns.

Section 11.6 Governing Law; Severability.

THIS AGREEMENT IS GOVERNED BY AND SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF DELAWARE, EXCLUDING ANY CONFLICT-OF-LAWS RULE OR PRINCIPLE THAT MIGHT REFER THE GOVERNANCE OR THE CONSTRUCTION OF THIS AGREEMENT TO THE LAW OF ANOTHER JURISDICTION. In the event of a direct conflict between the provisions of this Agreement and (a) any provision of the Organizational Certificate, or (b) any mandatory, non-waivable provision of the Delaware Act, such provision of the Organizational Certificate or the Delaware Act shall control. If any provision of the Delaware Act provides that it may be varied or superseded in the limited liability company agreement (or otherwise by agreement of the members or managers of a limited liability company), such provision shall be deemed superseded and waived in its entirety if this Agreement contains a provision addressing the same issue or subject matter. If any provision of this Agreement or the application thereof to any Person or circumstance is held invalid or unenforceable to any extent, (a) the remainder of this Agreement and the application of that provision to other Persons or circumstances is not affected thereby and that provision shall be enforced to the greatest extent permitted by Law, and (b) the Members or Board (as the case may be) shall negotiate in good faith to replace that provision with a new provision that is valid and enforceable and that puts the Members in substantially the same economic, business and legal position as they would have been in if the original provision had been valid and enforceable.

Section 11.7 Further Assurances. In connection with this Agreement and the transactions contemplated hereby, each Member shall execute and deliver any additional documents and instruments and perform any additional acts that may be necessary or appropriate to effectuate and perform the provisions of this Agreement and those transactions.

Section 11.8 Offset. Whenever the Company is to pay any sum to any Member, any amounts that a Member owes the Company may be deducted from that sum before payment.
