The members of the Board of Directors shall be appointed by the Member, provided that at least three of such members must meet the independence, qualification and experience requirements of the New York Stock Exchange, of Section 10A(m)(3) of the Securities Exchange Act of 1934 (or any successor Law), the rules and regulations of the SEC, other applicable Law (each, an “Independent Director”); provided, however, that if at any time there are not at least three Independent Directors serving as Directors, the Board of Directors shall still have all powers and authority granted to it hereunder, but the Board of Directors and the Member shall endeavor to elect additional Independent Directors to come into compliance with this Section 6.1(b)(i).

(ii) Term; Resignation; Vacancies; Removal. Each Director shall hold office until his successor is appointed and qualified or until his earlier resignation or removal. Any Director may resign at any time upon written notice to the Board, the Chairman (or Co-Chairmen, if applicable) of the Board, or to the Chief Executive Officer (or Co-Chief Executive Officers, if applicable). Such resignation shall take effect at the time specified therein, and unless otherwise specified therein no acceptance of such resignation shall be necessary to make it effective. Vacancies and newly created directorships resulting from any increase in the authorized number of Directors or from any other cause shall be filled by the Member. Any Director may be removed, with or without cause, by the Member at any time, and the vacancy in the Board caused by any such removal shall be filled by the Member.

(iii) Voting; Quorum. Unless otherwise required by the Act, other Law or the provisions hereof,

(A) each member of the Board of Directors shall have one vote; and

(B) the presence at a meeting of a majority of the members of the Board of Directors shall constitute a quorum at any such meeting for the transaction of business; and

(C) subject to the provisions of Section 6.1(b)(iv) the act of the members of the Board of Directors present at a meeting duly called in accordance with Section 6.1(b)(v) at which a quorum is present shall be deemed to constitute the act of the Board of Directors.

(iv) Required Vote for Certain Actions.

(A) Unanimous Vote of Directors. Any action by the Company, or by the Company in its capacity as general partner of the MLP, that would cause the Company to be taxable as a corporation for federal tax purposes, shall require approval by a Unanimous Vote, except as otherwise provided in this Agreement.

(B) Majority Vote of Directors. Except for matters that require a Member Approval or a Unanimous Vote and matters specified in Section 6.3 as within the authority of the Chief Executive Officer (or Co-Chief Executive Officers, as applicable) (but subject at all times to the direction and control of the Board), actions by the Company, or by the Company in its capacity as general partner of the MLP, shall require approval by a Majority Vote.

(v) Meetings. Regular meetings of the Board of Directors shall be held at such times and places as shall be designated from time to time by resolution of the Board of Directors. Special meetings of the Board of Directors or meetings of any committee thereof may be called by written request authorized by any member of the Board of Directors or a committee thereof on at least 24 hours prior written notice to the other members of such Board or committee, provided, that such notice requirement may be waived with respect to a particular special meeting of the Board of Directors by a majority of the members of the Board of Directors. Any such notice need not state the purpose of such meeting, except as may otherwise be required by law. Attendance of a Director at a meeting (including pursuant to the last sentence of this Section 6.2(b)(v)) shall constitute a waiver of notice of such meeting, except where such Director attends the meeting for the express purpose of objecting to the transaction of any business on the ground that the meeting is not lawfully called or convened. Any action required or permitted to be taken at a meeting of the Board of Directors or any committee thereof may be taken without a meeting, without prior notice and without a vote if a consent or consents in writing, setting forth the action so taken, are signed by at least as many members of the Board of Directors or committee thereof as would have been required to take such action at a meeting of the Board of Directors or such committee. Members of the Board of Directors or any committee thereof may participate in and hold a meeting by means of conference telephone, video conference or similar communications equipment by means of which all Persons participating in the meeting can hear each other, and participation in such meetings shall constitute presence in person at the meeting.

6.4 Indemnification.

(a) To the fullest extent permitted by Law but subject to the limitations expressly provided in this Agreement, each Indemnitee shall be indemnified and held harmless by the Company from and against any and all losses, claims, damages, liabilities, joint or several, expenses (including reasonable legal fees and expenses), judgments, fines, penalties, interest, settlements and other amounts arising from any and all claims, demands, actions, suits or proceedings, whether civil, criminal, administrative or investigative, in which any such Indemnitee may be involved, or is threatened to be involved, as a party or otherwise, by reason of such person’s status as an Indemnitee; provided, however that the Indemnitee shall not be indemnified and held harmless if there has been a final and non-appealable judgment entered by a court of competent jurisdiction determining that, in respect of the matter for which the Indemnitee is seeking indemnification pursuant to this Section 6.4, the Indemnitee acted in bad faith or engaged in fraud, willful misconduct, or in the case of a criminal matter, acted with knowledge that the Indemnitee’s conduct was unlawful; provided, further, no indemnification pursuant to this Section 6.4 shall be available to the Members or their Affiliates (other than the MLP and any Group Member) with respect to its or their obligations incurred pursuant to the Underwriting Agreement. The termination of any action, suit or proceeding by judgment, order, settlement, conviction or upon a plea of nolo contendere, or its equivalent, shall not create a presumption that the Indemnitee acted in a manner contrary to that specified above. Any indemnification pursuant to this Section 6.4 shall be made only out of Company Assets, it being agreed that a Member shall not be personally liable for such indemnification and shall have no obligation to contribute or loan any monies or property to the Company to enable it to effectuate such indemnification.

(b) To the fullest extent permitted by Law, expenses (including reasonable legal fees and expenses) incurred by an Indemnitee who is indemnified pursuant to Section 6.4(a) in defending any Claim shall, from time to time, be advanced by the Company prior to the final disposition of such Claim upon receipt by the Company of an undertaking by or on behalf of the Indemnitee to repay such amount if it shall be determined that the Indemnitee is not entitled to be indemnified as authorized in this Section 6.4.

(c) The indemnification provided by this Section 6.4 shall be in addition to any other rights to which an Indemnitee may be entitled under any agreement, as a matter of Law or otherwise, both as to actions in the Indemnitee’s capacity as an Indemnitee and as to actions in any other capacity, and shall continue as to an Indemnitee who has ceased to serve in such capacity and shall inure to the benefit of the heirs, successors, assigns and administrators of the Indemnitee.

(d) The Company may purchase and maintain insurance, on behalf of the members of the Board of Directors, the Officers and such other Persons as the Board shall determine, against any liability that may be asserted against or expense that may be incurred by such Person in connection with the Company’s activities, regardless of whether the Company would have the power to indemnify such Person against such liability under the provisions of this Agreement.

(e) For purposes of this Section 6.4, the Company shall be deemed to have requested an Indemnitee to serve as fiduciary of an employee benefit plan whenever the performance by the Indemnitee of such Indemnitee’s duties to the Company also imposes duties on, or otherwise involves services by, the Indemnitee to the plan or participants or beneficiaries of the plan; excise taxes assessed on an Indemnitee with respect to an employee benefit plan pursuant to Applicable Law shall constitute “fines” within the meaning of Section 6.4(a) and action taken or omitted by the Indemnitee with respect to an employee benefit plan in the performance of such Indemnitee’s duties for a purpose reasonably believed by such Indemnitee to be in the interest of the participants and beneficiaries of the plan shall be deemed to be for a purpose which is in, or not opposed to, the best interests of the Company.

(f) In no event may an Indemnitee subject the Members to personal liability by reason of the indemnification provisions set forth in this Agreement.

(g) An Indemnitee shall not be denied indemnification in whole or in part under this Section 6.4 because the Indemnitee had an interest in the transaction with respect to which the indemnification applies if the transaction is otherwise permitted by the terms of this Agreement.

(h) The provisions of this Section 6.4 are for the benefit of the Indemnitees, their heirs, successors, assigns and administrators and shall not be deemed to create any rights for the benefit of any other Persons.

(i) No amendment, modification or repeal of this Section 6.4 or any provision hereof shall in any manner terminate, reduce or impair either the right of any past, present or future Indemnitee to be indemnified by the Company or the obligation of the Company to indemnify any such Indemnitee under and in accordance with the provisions of this Section 6.4 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted, provided such Person became an Indemnitee hereunder prior to such amendment, modification or repeal.

(j) No member of the Board of Directors or Member shall be liable to the Company or to any Member for any loss suffered by the Company unless such loss is caused by such Director’s or Member’s gross negligence, willful misconduct, intentional violation of law or material breach of this Agreement. No member of the Board of Directors or Member shall be liable for errors in judgment or for any acts or omissions that do not constitute gross negligence, willful misconduct, intentional violation of law or material breach of this Agreement. Any member of the Board of Directors or Member may consult with counsel and accountants in respect of Company affairs and, provided such Director or Member acts in good faith reliance upon the advice or opinion of such counsel or accountants, such Director or Member shall not be liable for any loss suffered by the Company in reliance thereon.

(k) THE PROVISIONS OF THE INDEMNIFICATION PROVIDED IN THIS SECTION 6.4 ARE INTENDED BY THE MEMBERS TO APPLY EVEN IF SUCH PROVISIONS HAVE THE EFFECT OF EXCULPATING THE INDEMNITEE FROM LEGAL RESPONSIBILITY FOR THE CONSEQUENCES OF SUCH PERSON’S NEGLIGENCE, FAULT OR OTHER CONDUCT, SUBJECT TO LIMITS UNDER APPLICABLE LAW.

6.5 Reliance by Third Parties.

(a) Notwithstanding anything to the contrary in this Agreement, any Person dealing with the Company shall be entitled to assume that the Chief Executive Officer or any Person authorized by the Board to act on behalf of and in the name of the Company (each an “Authorized Person”) has full power and authority to encumber, sell or otherwise use in any manner any and all assets of the Company and to enter into any authorized contracts on behalf of the Company, and such Person shall be entitled to deal with any Authorized Person as if it were the Company’s sole party in interest, both legally and beneficially. In no event shall any Person dealing with any Authorized Person be obligated to ascertain that the terms of this Agreement have been complied with or to inquire into the necessity of any act or action of any Authorized Person.

(b) Each and every certificate, document or other instrument executed on behalf of the Company by any Authorized Person shall be conclusive evidence in favor of any and every Person relying thereon or claiming thereunder that (i) at the time of the execution and delivery of such certificate, document or instrument, this Agreement was in full force and effect, (ii) the Person executing and delivering such certificate, document or instrument was duly authorized and empowered to do so for and on behalf of the Company and (iii) such certificate, document or instrument was duly executed and delivered in accordance with the terms and provisions of this Agreement and is binding upon the Company.

6.6 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 of Directors 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 Common Units excluding Common 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 of Directors 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 of Directors may also adopt a resolution or course of action that has not received Special Approval. If Special Approval is not sought and the Board of Directors 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) above, then it shall be presumed that, in making its decision, the Board of Directors 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 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 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.

Article 8

Dissolution, Winding-up and Termination

(i) Member Approval to dissolve the Company; and

(ii) entry of a decree of judicial dissolution of the Company under Section 18-802 of the Act; provided that the Board shall not submit an application for a decree of judicial dissolution unless and until all amounts payable under the obligations of the Company have been indefeasibly paid in full.

(b) The Company shall not dissolve other than pursuant to Section 8.1(a).

8.2 Winding-Up and Termination.

(a) The winding up of the Company shall commence on the day of the applicable Dissolution Event, but this Agreement shall not terminate until the Company Assets have been distributed in accordance with the terms of this Article 8. The Board shall act as liquidator (the “Liquidator”). The Liquidator shall immediately proceed to wind up and terminate the affairs of the Company and make final distributions as provided herein and in the Act. The costs of liquidation shall be borne as a Company expense. Until final distribution, the Liquidator shall continue to operate the business and assets of the Company with all of the power and authority of the Board. Maintenance of property, borrowing and expenditures of Company funds for legitimate Company purposes to effectuate or facilitate the winding up or the liquidation of the Company affairs shall be authorized if the Liquidator, in the exercise of its business judgment, believes that the interests of the Company would be best served thereby, and such actions shall not be construed to involve a continuation of the Company. 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 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 the Company’s funds all of the debts, liabilities and obligations of the Company (including all expenses incurred in winding up) 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 Company Assets (including cash) shall be distributed among the Members in accordance with the ratio of the positive balances in their respective Capital Accounts, as determined after taking into account all Capital Account adjustments (other than those made by reason of distributions pursuant to this Section 8.2(a)(iii)) for the taxable period during which the Liquidation Date occurs.

(b) The distribution of cash or other assets to a Member in accordance with the provisions of this Section 8.2 constitutes a complete return to the Member of its Capital Contributions and a complete distribution to the Member of its Member Interest and all the Company Assets and constitutes a compromise to which all Members have consented pursuant to Section 18-502(b) of the Act.

8.3 Certificate of Cancellation. Upon completion of the distribution of Company Assets as provided herein, the Liquidator (or such other Person or Persons as the Act may require or permit) shall file a certificate of cancellation with the Secretary of State of the State of Delaware, cancel any other filings made pursuant to Section 2.5, and take such other actions as may be necessary to terminate the existence of the Company. Upon the filing of such certificate of cancellation, the existence of the Company shall terminate (and the Term shall end).

8.4 Certain Matters Concerning a Member.

(a) Notwithstanding any other provisions 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 business of the Company shall continue without dissolution.

(b) The dissolution, liquidation or termination of a Member shall not cause the termination or dissolution of the Company, and the business of the Company shall continue without dissolution.

10.14 Confidentiality.

(a) Each Member agrees that it will not disclose to any Person or otherwise use to its benefit or to the benefit of any third party, including any Affiliate of such Member, in any way whatsoever any Confidential Information, without the consent of the Board or the Chief Executive Officer, except as may be necessary to comply with any Applicable Law, directive or procedure of any Governmental Authority. Each Member will notify the Company before disclosing such information pursuant to any such Applicable Law, directive or procedure to give the Company the opportunity to seek a protective order. The restrictions set forth in this Section 10.14 shall not apply to information that (i) is, or after the date of this Agreement, becomes generally available to the public, other than through the wrongful act of any Person, (ii) after the date of this Agreement, is communicated to the Member disclosing such information in a non confidential manner by a third party without any breach of this Section 10.14 or breach of any confidentiality obligations of such third party to any of the Members or (iii) was or is already in the possession of the Person receiving such information at the time of its disclosure by the Member disclosing such information, provided, that such Person came into possession of such information through means other than that which would constitute a breach of this Section 10.14 or a breach of the confidentiality obligations of any third party to the Member disclosing such information. This Section 10.14 shall survive with respect to a former Member for a period of two years after the date that such Member ceases to be a Member.

(c) The Members agree that no adequate remedy at law exists for a breach or threatened breach of any of the provisions of this Section 10.14, the continuation of which unremedied will cause the Company to suffer irreparable harm. Accordingly, the Members agree that the Company shall be entitled, in addition to other remedies that may be available to them, to immediate injunctive relief from any breach of any of the provisions of this Section 10.14 and to specific performance of their rights hereunder, as well as to any other remedies available at law or in equity.
