(iv)                              Persons appointed pursuant to Section 5.1(b)(i)(B) by the Sole Member may be removed at any time, with or without cause, by the Sole Member, acting through the Holdings GP Board.  In the event of the death, resignation or removal of any such Director, the Sole Member acting through the Holdings GP Board may designate a replacement Director.  In the event the individual serving as Chief Executive Officer of the Company no longer holds such office for any reason, such individual shall be automatically removed as a Director and the successor to such individual as Chief Executive Officer of the Company shall, by virtue of such appointment, be designated to replace such individual as a Director.

(c)                                  Subject to the terms and conditions set forth below, for so long as an Initial Designating Member has designated an individual to serve as an observer to the Holdings GP Board pursuant to the terms of the Holdings GP LLC Agreement, that same individual (an “Observer”) shall have the right to receive notice of and attend meetings of the Board in an

7

observer capacity until such Observer ceases to serve as an observer to the Holdings GP Board or such Initial Designating Member rescinds its request to receive such information in writing, the Observer shall be entitled to receive copies of information routinely provided to the Directors; provided, that the failure to give any such notice or documents or information shall not affect the validity of any action taken by the Board.  The following terms and conditions shall apply to any service by an Observer in an observer capacity:

(ii)                                  In recognition that the Initial Designating Member or one or more of its Affiliates are currently, or may become, engaged in certain aspects of the midstream crude oil, refined products, natural gas and liquefied petroleum gas or other current or future energy infrastructure-related activities that may be deemed to be competitive with the MLP, (1) written materials may be redacted or withheld from the Initial Designating Member or the Observer pursuant to (iii) below and (2) the Observer may be excluded from relevant portions of the Board meetings or committee meetings pursuant to (iv) below.

(iii)                               Written materials may be redacted or withheld from the Initial Designating Member or the Observer, if the Board, the Chairman, the Chief Executive Officer or the general counsel of the Company reasonably believe that providing such information (1) would result in a potential breach of confidentiality agreements between third parties and the Company Group or the MLP and its Subsidiaries; (2) may otherwise disadvantage the Company Group, the MLP or any of its Subsidiaries in ongoing commercial dealings with the Initial Designating Member or any of its affiliates; (3) is necessary or advisable for the protection and retention of any attorney-client privilege; or (4) could result in the competitive positioning of the Company Group or the MLP and its Subsidiaries being compromised.

(iv)                              At the discretion of a majority of the Directors (or any committee of the Board) then in attendance, the Observer may be excluded from relevant portions of the Board meetings or committee meetings if such majority reasonably believes that, the Observer’s attendance (1) would result in a potential breach of confidentiality agreements between third parties and the Company Group or the MLP and its Subsidiaries; (2) may otherwise disadvantage the Company Group, the MLP or any of its Subsidiaries in ongoing commercial dealings with the Initial Designating Member or any of its affiliates; (3) is necessary or advisable for the protection and retention of any attorney-client privilege; or (4) could result in in the competitive positioning of the Company Group or the MLP and its Subsidiaries being compromised;

(v)                                 The Initial Designating Member may eliminate the foregoing restrictions in clauses (ii), (iii) and (iv) above by requesting information or requesting that its Observer not be excluded and, if applicable, agreeing in writing to be bound by any applicable confidentiality agreements that would permit disclosure of the information being redacted or withheld, unless such disclosure or presence of the Observer would (1)

8

adversely affect the retention of any attorney-client privilege or (2) disadvantage the Company Group, the MLP or any of its Subsidiaries in ongoing commercial dealings with the Initial Designating Member or any of its affiliates.

(vi)                              With respect to materials provided to the Initial Designating Member pursuant to Section 5.1(b)(ii) or otherwise provided by the Company Group without solicitation by the Initial Designating Member, the Initial Designating Member shall not be presumed to have misused such information solely because its Observer may have retained a mental impression of such information in connection with the Initial Designating Member’s participation in activities competitive the Company Group or the MLP and its Subsidiaries.  This Section 5.1(b)(vi) shall not apply with respect to information provided to the Initial Designating Member pursuant to Section 5.2(b)(v) or otherwise provided upon the Initial Designating Member’s request.

ARTICLE 6

LIABILITY AND INDEMNIFICATION

6.1                               Limitation on Liability of Members, Directors and Officers.

(a)                                 Subject to, and as limited by, the provisions of this Agreement, the Sole Member and the Directors, in the performance of their duties as such, shall not, to the maximum extent permitted by the Act or other applicable law, owe any duties (including fiduciary duties) as a member or Director of the Company, notwithstanding anything to the contrary in existing law, in equity or otherwise; provided, however, that for the avoidance of doubt nothing set forth herein shall be deemed to limit the obligations of the “General Partner” under the MLP Partnership Agreement.  Notwithstanding anything to the contrary set forth in this Agreement, no Indemnitee shall be liable for monetary damages to the Company or the Sole Member, for losses sustained or liabilities incurred as a result of any act or omission of an Indemnitee in connection with the conduct of the business or affairs of the Company unless there has been a final and non-appealable judgment entered by a court of competent jurisdiction determining that, in respect of the matter in question, 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 criminal. To the fullest extent permitted by Section 18-1101(c) of the Act, a Designated Director, in performing his or her obligations under this Agreement, shall be entitled to act or omit to act at the direction of the Designating Member who designated such Director, considering only such factors, including the separate interests of such Designating Member, as such Director or Designating Member chooses to consider, and any action of a Director or failure to act, taken or omitted in good faith reliance on the foregoing provisions of this Section 6.1 shall not constitute a breach of any duty including any fiduciary duty on the part of the Director or Designating Member to the Company or the Sole Member or any other Director.  Except as required by the Act, the Company’s debts, obligations, and liabilities, whether arising in contract, tort or otherwise, shall be solely the debts, obligations and liabilities of the Company, and no Indemnitee shall be personally responsible for any such debt, obligation or liability of the Company solely by reason of being an Indemnitee. The provisions of this Agreement, to the extent that they restrict, eliminate or otherwise modify the duties and liabilities, including fiduciary duties, of any Indemnitee otherwise existing at law or in equity, are agreed by Sole Member to replace such duties and liabilities of such Indemnitee.  To the fullest extent permitted

13

by law, in connection with any action or inaction of, or determination made by, any Indemnitee with respect to any matter relating to the Company, it shall be presumed that the Indemnitee acted in a manner that satisfied the contractual standards set forth in this Agreement, and in any proceeding brought by or on behalf of the Sole Member challenging any such action or inaction of, or determination made by, any Indemnitee, the Person bringing or prosecuting such proceeding shall have the burden of overcoming such presumption.

(b)                                 Any Indemnitee may rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, bond, debenture or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties.

(c)                                  No amendment, modification or repeal of this Section 6.1 or any provision hereof shall in any manner terminate, reduce or impair the waiver or limitation on liability with respect to any past, present or future Indemnitee under and in accordance with the provisions of this Section 6.1 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.

6.2                               Indemnification.

(a)                                 Notwithstanding anything to the contrary set forth in this Agreement and except as required by the Act, to the fullest extent permitted by law but subject to the limitations expressly provided in this Agreement, the Company shall indemnify and hold harmless the Indemnitees (when not acting in violation of this Agreement or applicable law) from and against any and all losses, claims, demands, costs, damages, liabilities, expenses of any nature (including reasonable attorneys’ fees and disbursements), judgments, fines, settlements and other amounts arising from any and all claims, demands, actions, suits or proceedings, civil, criminal, administrative or investigative, in which an Indemnitee may be involved, or threatened to be involved, as a party or otherwise, by reason of his, her or its status as an Indemnitee, if such Indemnitee acted in good faith and in a manner he or she subjectively believed to be in, or not opposed to, the interests of the Company and with respect to any criminal proceeding, had no reason to believe his, her or its conduct was unlawful.

(b)                                 Expenses incurred by an Indemnitee in defending any claim, demand, action, suit or proceeding subject to Section 6.2(a) shall, from time to time, be advanced by the Company prior to the final disposition of such claim, demand, action, suit or proceeding upon receipt by the Company of an undertaking by or on behalf of the Indemnitee to repay such amounts if it is ultimately determined that the Indemnitee is not entitled to be indemnified as authorized in this Section 6.2.

(c)                                  The indemnification provided by this Section 6.2 shall be in addition to any other rights to which an Indemnitee may be entitled pursuant to any approval of the Board, as a matter of law or equity, or otherwise, and shall continue as to an Indemnitee who has ceased to hold the status with respect to which it was an Indemnitee and shall inure to the benefit of the heirs, successors, assigns, and administrators of such Indemnitee; provided, however, that in the event such Indemnitee is also an Affiliate of a Designating Member, the vote of the Designated

14

Director designated by such Designating Member shall be disregarded for purposes of the Board’s vote pursuant to this Section 6.2(c).

(d)                                 The Company may purchase and maintain directors and officers insurance or similar coverage for its Directors and Officers in such amounts and with such deductibles or self-insured retentions as determined by the Board.

(e)                                  Any indemnification hereunder shall be satisfied only out of the assets of the Company, and the Sole Member shall not be subject to personal liability by reason of the indemnification provisions under this Section 6.2.

(f)                                   An Indemnitee shall not be denied indemnification in whole or in part under this Section 6.2 because the Indemnitee had an interest in the transaction with respect to which the indemnification applies if the transaction was otherwise permitted by the terms of this Agreement and all material facts relating to such Indemnitee’s interest were adequately disclosed to the Board at the time the transaction was consummated.

(g)                                  Subject to Section 6.2(c), the provisions of this Section 6.2 are for the benefit of the Indemnitees and the heirs, successors, assigns and administrators of the Indemnitees and shall not be deemed to create any rights for the benefit of any other Persons.

(h)                                 No amendment, modification or repeal of this Section 6.2 or any provision hereof shall in any manner terminate, reduce or impair the right of any past, present or future Indemnitee to be indemnified by the Company or any Affiliate of the Company, nor the obligations of the Company or such Affiliate to indemnify any such Indemnitee under and in accordance with the provisions of this Section 6.2 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.
