ARTICLE 3
CAPITALIZATION OF THE COMPANY

     3.1 Initial Capital Contributions. The Percentage Interest of each Member as of the date hereof is as set forth on Schedule 1 hereto, which shall be amended from time to time in accordance with the terms hereof (including, but not limited to, upon the making of additional Capital Contributions pursuant to Section 3.2(b)) to reflect appropriate adjustments to such Percentage Interests.

     3.2 Additional Capital Contributions.

     (a) Except for Capital Contributions from each Member in proportion to such Member’s then outstanding Percentage Interest in respect of the General Partner’s Percentage for equity issuances by the MLP, and for equity issuances approved pursuant to Section 7.9(b)(ii), no Member shall be required to make any additional Capital Contribution.

     (b) Subject to the approval of a Majority in Interest pursuant to Section 7.9, the Company may offer additional Membership Interests to any Person with the approval of the Board. Such approval of the Majority in Interest shall also include their approval of any related valuations of Gross Asset Value by the Board and, if such Majority in Interest approves such issuance without approving such valuation, Gross Asset Value shall be determined by a third Person familiar with the valuation of such transactions selected by the Majority in Interest not later than ten (10) days after their approval of such issuance or, if the Majority in Interest fails to so select a third Person, then such third Person will be selected in accordance with the rules and procedures of the American Arbitration Association in Houston, Texas. If any additional Capital Contributions are made by Members but not in proportion to their respective Percentage Interests, the Percentage Interest of each Member shall be adjusted such that each Member’s revised Percentage Interest determined immediately following each such additional Capital Contribution shall be equal to a fraction (i) the numerator of which is the sum of (A) the positive Capital Account balance of the Member determined immediately preceding the date such additional Capital Contribution is made (such Capital Account to be computed by adjusting the book value for Capital Account purposes of each Company asset to equal its Gross Asset Value as of such date, as provided in subparagraph (b) of the definition herein of “Gross Asset Value”), and (B) such additional Capital Contribution, if any, made by such Member, and (ii) the denominator of which is the sum of the positive Capital Account balances immediately preceding the date such additional Capital Contribution is made plus additional Capital Contributions of all Members on the date of such additional Capital Contribution, including Capital Contributions of any new Members (in each case calculated as provided in (i) above). The names, addresses and Capital Contributions of the Members shall be reflected in the books and records of the Company.

     3.3 Loans.

     (a) No Member shall be obligated to loan funds to the Company. Loans by a Member to the Company shall not be considered Capital Contributions. The amount of any such loan shall be a debt of the Company owed to such Member in accordance with the terms and conditions upon which such loan is made.

     (b) A Member may (but shall not be obligated to) guarantee a loan made to the Company. If a Member guarantees a loan made to the Company and is required to make payment pursuant to such guarantee to the maker of the loan, then the amounts so paid to the maker of the loan shall be treated as a loan by such Member to the Company and not as an additional Capital Contribution.

     3.4 Maintenance of Capital Accounts.

     (a) The Company shall maintain for each Member a separate Capital Account with respect to the Membership Interest owned by such Member in accordance with the following provisions:

     (i) To each Member’s Capital Account there shall be credited (A) such Member’s Capital Contributions, (B) such Member’s share of Profits and (C) the amount of any Company liabilities assumed by such Member or which are secured by any

Property distributed to such Member. The principal amount of a promissory note which is not readily traded on an established securities market and which is contributed to the Company by the maker of the note (or a Member related to the maker of the note within the meaning of Regulation Section 1.704-1(b)(2)(ii)(c)) shall not be included in the Capital Account of any Member until the Company makes a taxable disposition of the note or until (and only to the extent) principal payments are made on the note, all in accordance with Regulation Section 1.704-1(b)(2)(iv)(d)(2);

     (ii) To each Member’s Capital Account there shall be debited (A) the amount of money and the Gross Asset Value of any Property distributed or treated as an advance distribution to such Member pursuant to any provision of this Agreement (including without limitation any distributions pursuant to Section 4.1), (B) such Member’s share of Losses and (C) the amount of any liabilities of such Member assumed by the Company or which are secured by any Property contributed by such Member to the Company;

     (iii) In the event Membership Interests are Transferred in accordance with the terms of this Agreement, the transferee shall succeed to the Capital Account of the transferor to the extent such Capital Account relates to the Transferred Membership Interests; and

     (iv) In determining the amount of any liability for purposes of Sections 3.4(a)(i) and (ii) there shall be taken into account Code Section 752(c) and any other applicable provisions of the Code and Regulations.

     (b) The foregoing Section 3.4(a) and the other provisions of this Agreement relating to the maintenance of Capital Accounts are intended to comply with Regulation Section 1.704-1(b) and, to the greatest extent practicable, shall be interpreted and applied in a manner consistent with such Regulation. The Board in its discretion and to the extent otherwise consistent with the terms of this Agreement shall (i) make any adjustments that are necessary or appropriate to maintain equality between the Capital Accounts of the Members and the amount of capital reflected on the Company’s balance sheet, as computed for book purposes, in accordance with Regulation Section 1.704-1(b)(2)(iv)(q), and (ii) make any appropriate modifications in the event unanticipated events might otherwise cause this Agreement not to comply with Regulation Section 1.704-1(b).

     3.5 Capital Withdrawal Rights, Interest and Priority. Except as expressly provided in this Agreement, no Member shall be entitled to (a) withdraw or reduce such Member’s Capital Contribution or to receive any distributions from the Company, or (b) receive or be credited with any interest on the balance of such Member’s Capital Contribution at any time.

ARTICLE 4
DISTRIBUTIONS

     4.1 Distributions of Available Cash. An amount equal to 100% of Available Cash with respect to each fiscal quarter shall be distributed to the Members in proportion to their relative Percentage Interests within forty-five days after the end of such quarter.

     4.2 Persons Entitled to Distributions. All distributions of Available Cash to Members for a fiscal quarter pursuant to Section 4.1 or approved pursuant to Section 7.9(b) shall be made to the Members shown on the records of the Company to be entitled thereto as of the last day of such quarter, unless the transferor and transferee of any Membership Interest otherwise agree in writing to a different distribution and such distribution is consented to in writing by the Board.

     4.3 Limitations on Distributions.

     (a) Notwithstanding any provision of this Agreement to the contrary, no distributions shall be made except pursuant to this Article 4 or Article 10 or as approved pursuant to Section 7.9(b).

     (b) Notwithstanding any provision of this Agreement to the contrary, no distribution hereunder shall be permitted if such distribution would violate Section 18-607 of the Act or other applicable law.

ARTICLE 5
ALLOCATIONS

     5.1 Profits. Profits for any Taxable Year shall be allocated:

     (a) first, to those Members to which Losses have previously been allocated pursuant to Section 5.2(c) hereof so as to bring each such Member’s Capital Account to zero, pro rata in accordance with the sum of each such Member’s Losses; and

     (b) second, any remaining Profits shall be allocated among the Members in proportion to their respective Percentage Interests.

     5.2 Losses. Losses for any Taxable Year shall be allocated:

     (a) first, to the Members to which Profits have previously been allocated pursuant to Section 5.1(b) to the extent of such Profits;

     (b) second, to Members in proportion to their positive Capital Account balances until such Capital Account balances have been reduced to zero; and

     (c) third, any remaining Losses shall be allocated among the Members in proportion to their respective Percentage Interests.

     5.3 Regulatory Allocations.

     (a) Gross Income Allocation. In the event any Member has an Adjusted Capital Account Deficit at the end of any Taxable Year, such Member shall be specially allocated items of Company income and gain in the amount of such deficit balance as quickly as possible; provided, that an allocation pursuant to this Section 5.3(a) shall be made only if and to the extent that such Member would have an Adjusted Capital Account Deficit balance after all other allocations provided for in this Article 5 have been made.

     (b) Qualified Income Offset. In the event any Member unexpectedly receives any adjustments, allocations, or distributions described in Regulation Sections 1.704-1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5) or 1.704-1(b)(2)(ii)(d)(6), items of Company income and gain shall be specially allocated to such Member in an amount and manner sufficient to eliminate, to the extent required by the Regulations, the Adjusted Capital Account Deficit of such Member as quickly as possible, provided, that an allocation pursuant to this Section 5.3(b) shall be made only if and to the extent that such Member would have an Adjusted Capital Account Deficit after all other allocations provided for in this Article 5 have been made.

     (c) Curative Allocations. The allocations set forth in Sections 5.3(a) and (b) hereof (the “Regulatory Allocations”) are intended to comply with certain requirements of the Regulations. It is the intent of the Members that, to the extent possible, all Regulatory Allocations shall be offset either with other Regulatory Allocations or with special allocations of other items of Company income, gain, loss or deduction pursuant to this Section 5.3(c). Therefore, notwithstanding any other provision of this Article 5 (other than the Regulatory Allocations), the Board shall make such offsetting special allocations of income, gain, loss or deduction in whatever manner it determines appropriate so that, after such offsetting allocations are made, each Member’s Capital Account balance is, to the extent possible, equal to the Capital Account balance such Member would have had if the Regulatory Allocations were not part of this Agreement and all such items were allocated pursuant to Sections 5.1 and 5.2 without regard to the Regulatory Allocations.

     5.4 Tax Allocations: Code Section 704(c).

     (a) Except as otherwise provided herein, for federal income tax purposes, (i) each item of income, gain, loss and deduction shall be allocated among the Members in the same manner as its correlative item of “book” income, gain, loss or deduction is allocated pursuant to Sections 5.1 and 5.2, and (ii) each tax credit shall be allocated to the Members in the same manner as the receipt or expenditure giving rise to such credit is allocated pursuant to Section 5.1 and 5.2.

     (b) In accordance with Code Section 704(c) and the Regulations thereunder, income, gain, loss and deduction with respect to any Property contributed to the capital of the Company shall, solely for tax purposes, be allocated among the Members so as to take account of any variation between the adjusted basis of such Property to the Company for federal income tax purposes and its initial Gross Asset Value (computed in accordance with the definition herein of “Gross Asset Value”).

     (c) In the event the Gross Asset Value of any Company asset is adjusted pursuant to subparagraph (b) of the definition herein of “Gross Asset Value”, subsequent allocations of income, gain, loss and deduction with respect to such asset shall take account of any variation between the adjusted basis of such asset for federal income tax purposes and its Gross Asset Value in the same manner as under Code Section 704(c) and the Regulations thereunder.

     (d) Any elections or other decisions relating to such allocations shall be made by the Board in any manner that reasonably reflects the purpose and intention of this Agreement; provided, that the Company, in the discretion of the Board, may make, or not make, “curative” or

“remedial” allocations (within the meaning of the Regulations under Code Section 704(c)) including, but not limited to, “curative” allocations which offset the effect of the “ceiling rule” for a prior Taxable Year (within the meaning of Regulation Section 1.704-3(c)(3)(ii)) and “curative” allocations from disposition of contributed property (within the meaning of Regulation Section 1.704-3(c)(3)(iii)(B)). Allocations pursuant to this Section 5.4 are solely for purposes of federal, state, and local taxes and shall not affect, or in any way be taken into account in computing, any Member’s Capital Account or share of Profits, Losses, other items, or distributions pursuant to any provision of this Agreement.

     5.5 Change in Percentage Interests. In the event that the Members’ Percentage Interests change during a Taxable Year, Profits and Losses shall be allocated taking into account the Members’ varying Percentage Interests for such Taxable Year, determined on a daily, monthly or other basis as determined by the Board, using any permissible method under Code Section 706 and the Regulations thereunder.

     5.6 Withholding. Each Member hereby authorizes the Company to withhold from income or distributions allocable to such Member and to pay over any taxes payable by the Company or any of its Affiliates as a result of such Member’s participation in the Company; if and to the extent that the Company shall be required to withhold any such taxes, such Member shall be deemed for all purposes of this Agreement to have received a distribution from the Company as of the time such withholding is required to be paid, which distribution shall be deemed to be a distribution to such Member to the extent that the Member is then entitled to receive a distribution. To the extent that the aggregate of such distributions in respect of a Member for any period exceeds the distributions to which such Member is entitled for such period, the amount of such excess shall be considered a demand loan from the Company to such Member, with interest at the rate of interest per annum that Citibank, N.A., or any successor entity thereto, announces from time to time as its prime lending rate, which interest shall be treated as an item of Company income, until discharged by such Member by repayment, which may be made in the sole discretion of the Board out of distributions to which such Member would otherwise be subsequently entitled. The withholdings referred to in this Section 5.6 shall be made at the maximum applicable statutory rate under applicable tax law unless the Board shall have received an opinion of counsel or other evidence, satisfactory to the Board, to the effect that a lower rate is applicable, or that no withholding is applicable.

ARTICLE 6
MEMBERS’ MEETINGS

     6.1 Meetings of Members; Place of Meetings. Regular meetings of the Members shall be held on an annual basis or more frequently as determined by a Majority in Interest.

A Member expecting to be absent from a meeting shall be entitled to designate in writing (or orally; provided, that such oral designation is later confirmed in writing) a proxy (an “Authorized Representative”) to act on behalf of such Member with respect to such meeting (to the same extent and with the same force and effect as the Member who has

designated such Authorized Representative). Such Authorized Representative shall have full power and authority to act and take actions or refrain from taking actions as the Member by whom such Authorized Representative has been designated. Members and Authorized Representatives may participate in a meeting of the Members by means of conference telephone or other similar communication equipment whereby all Members or Authorized Representatives participating in the meeting can hear each other. Participation in a meeting in this manner shall constitute presence in person at the meeting, except when a Member or Authorized Representative participates for the express purpose of objecting to the transaction of any business on the ground that the meeting was not lawfully called or convened.

     6.2 Quorum; Voting Requirement. The presence, in person or by proxy, of a Majority in Interest of the Members shall constitute a quorum for the transaction of business by the Members.

     6.3 Proxies. At any meeting of the Members, every Member having the right to vote thereat shall be entitled to vote in person or by proxy appointed by an instrument in writing signed by such Member and bearing a date not more than one year prior to the date of such meeting.

     6.4 Action Without Meeting. Any action required or permitted to be taken at any meeting of Members of the Company may be taken without a meeting, without prior Notice and without a vote if a consent in writing setting forth the action so taken is signed by Members having not less than the minimum Percentage Interest that would be necessary to authorize or take such action at a meeting of the Members. Prompt Notice of the taking of any action taken pursuant to this Section 6.4 by less than the unanimous written consent of the Members shall be given to those Members who have not consented in writing.

     (a) (i) Except as otherwise provided hereunder, the business and affairs of the Company shall be managed by or under the direction of the Board, which shall, subject to Section 7.1(a)(iv), consist of eight (8) individuals designated as directors of the Company (the “Directors”) as follows: (A) subject to Section 7.1(a)(iv), each Initial Designating Member shall be entitled to designate one (1) Director, (B) a Majority in Interest shall elect three (3) Directors,

each of whom shall be Independent Directors, (C) the Chief Executive Officer of the Company shall be a Director and (D) any remaining Directors shall (at the discretion of the Majority in Interest or the Member with the power to elect or designate such Director hereunder, as applicable) be elected in accordance with the provisions of Section 7.1(a)(iv).

     (ii) At each annual meeting of the Members and at each special meeting of the Members called for the purpose of electing Directors (subject to the third to last sentence of this Section 7.1(a)(ii)), each Member shall be entitled to designate the number of Directors as set forth in Section 7.1(a)(i). Each Member shall cooperate with respect to calling and attending meetings of Members and electing the Directors designated by the Members, including voting in favor of Directors designated pursuant to Section 7.1(a)(i) and any replacement Directors pursuant to Section 7.1(a)(iii); provided, that the failure to hold any such meetings shall not limit or eliminate a Member’s right to designate Directors pursuant to Section 7.1(a)(i). Directors shall be elected to serve annual terms expiring on the date of the annual meeting of Members following such election. Each Director shall hold office until his or her successor is elected pursuant to this Section 7.1(a) or until his or her earlier death, resignation or removal. The provisions of Section 7.1(a)(i), (ii) and (iii) are subject to the limitations contained in Section 7.1(a)(iv).

     (iii) Any individual designated by a Member as a Director (other than Independent Directors and the Chief Executive Officer of the Company) may be removed at any time, with or without cause, only by such designating Member and the Members shall cooperate with respect to such removal, including voting in favor of such removal. Persons elected as an Independent Director may be removed at any time, with or without cause, by a vote of a Majority in Interest. Subject to Section 7.1(a)(iv), in the event of the death, resignation or removal of a Director (other than an Independent Director, the Chief Executive Officer of the Company), the Member that designated such Director may designate a replacement Director. In the event of the death, resignation or removal of an Independent Director, a Majority in Interest 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.

     (iv) Each Initial Designating Member shall have the right to designate a Director pursuant to Section 7.1(a)(i)(A) so long as such Member’s Percentage Interest is greater than 10% of all Membership Interests. In the event a Member ceases to have the right to designate a Director pursuant to Section 7.1(a)(i)(A), such individual designated by such Member shall be automatically removed as a Director and any Member with a Percentage Interest of greater than 25% and not otherwise entitled to designate a Director shall designate a replacement Director, or, if there is no such Member, a Majority in Interest shall elect a replacement Director and in either case such Director shall serve a term expiring on the date of the annual meeting of Members following such election and shall hold office until his or her successor is elected; provided, however, in the event that there is more than one Member with a Percentage Interest greater than 25% and not otherwise entitled to designate a Director, the Member who first accumulated a

Percentage Interest of 25% or greater shall be entitled to designate the replacement Director. At such time as no Member has the right to designate Directors pursuant to Section 7.1(a)(i)(A) or this Section 7.1(a)(iv), then the provisions of Sections 7.1(a)(i), (ii) and (iii) and the second sentence of this Section 7.1(a)(iv) shall terminate and the number of Directors comprising the Board shall be eight (8) and shall consist of at least three (3) Independent Directors and the Chief Executive Officer of the Company. All such Directors shall be elected by a Majority in Interest and shall serve annual terms expiring on the date of the annual meeting of Members following such election.

Any Director elected pursuant to this Section 7.1(a)(iv) may be removed, with or without cause, by a Majority in Interest. In the event of the death, resignation or removal of a Director, the remaining Directors may appoint a replacement Director. Notwithstanding any other provision of this Agreement, in no event shall both a Member and its Permitted Transferee be entitled to designate a Director pursuant to Section 7.1(a)(i)(A).

     (b) Except as otherwise expressly provided herein, the power and authority granted to the Board hereunder shall include all those necessary or convenient for the furtherance of the purposes of the Company and shall include the power to make or delegate to Officers all decisions with regard to the management, operations, assets, financing and capitalization of the Company.

Special meetings of the Board may be called at the request of the Chief Executive Officer or any two or more of the Directors upon delivery of written Notice sent to each other Director by the means most likely to reach such Director as may be determined by the Secretary in his best judgment so as to be received at least twenty-four hours prior to the time of such meeting. Notwithstanding anything contained herein to the contrary, such Notice may be telephonic if no other reasonable means are available. Such Notices shall be accompanied by a proposed agenda or statement of purpose.

     7.3 Quorum and Acts of the Board. A majority of the Directors shall constitute a quorum for the transaction of business at all meetings of the Board, and, except as otherwise provided in this Agreement, the act of a majority of the Directors present at any meeting at which there is a quorum shall be the act of the Board. If a quorum shall not be present at any meeting of the Board, the Directors present thereat may adjourn the meeting from time to time, without notice other than announcement at the meeting, until a quorum shall be present. Any action required or permitted to be taken at any meeting of the Board or of any committee thereof may be taken without a meeting, if all members of the Board or committee, as the case may be, consent thereto in writing, and the writing or writings are filed with the minutes of proceedings of the Board or committee.

     7.4 Electronic Communications. Members of the Board, or any committee designated by the Board, may participate in a meeting of the Board or any committee thereof by means of conference telephone or similar communications equipment through which all persons

participating in the meeting can hear each other, and such participation in a meeting shall constitute presence in person at the meeting.

     7.5 Committees of Directors. The Board, by unanimous resolution of all Directors present and voting at a duly constituted meeting of the Board or by unanimous written consent, may designate one or more committees, each committee to consist of one (1) or more of the Directors. In the event of the disqualification, resignation or removal of a committee member, the Board may appoint another member of the Board to fill such vacancy. Any such committee, to the extent provided in the Board’s resolution, shall have and may exercise all the powers and authority of the Board in the management of the Company’s business and affairs subject to any limitations contained herein or in the Act. Such committee or committees shall have such name or names as may be determined from time to time by resolution adopted by the Board. Each committee shall keep regular minutes of its meetings and report the same to the Board when required.

     7.6 Compensation of Directors. Each Director shall be entitled to reimbursement from the Company for all reasonable direct out-of-pocket expenses incurred by such Director in connection with attending Board meetings and such compensation as may be approved by a Majority in Interest.

     7.7 Directors as Agents. The Board, acting as a body pursuant to this Agreement, shall constitute a “manager” for purposes of the Act. No Director, in such capacity, acting singly or with any other Director, shall have any authority or right to act on behalf of or bind the Company other than by exercising the Director’s voting power as a member of the Board, unless specifically authorized by the Board in each instance.

     7.8 Officers; Agents. The Board shall have the power to appoint any Person or Persons as the Company’s officers (the “Officers”) to act for the Company and to delegate to such Officers such of the powers as are granted to the Board hereunder. 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 executory authority). The Officers may have such titles as the Board shall deem appropriate, which may include (but need not be limited to) Chairman of the Board, President, Chief Executive Officer, Executive Vice President, Vice President, Chief Operating Officer, Chief Financial Officer, Treasurer, Controller or Secretary. A Director may be an Officer. The Officers of the Company as of the date hereof shall continue in office subject to terms hereof. 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. 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 affirmative vote of a majority of the Board. Any vacancy occurring in any office of the Company shall be filled by a majority of the Board.

     7.9 Matters Requiring Member Approval. (a) Without the prior written consent of a Super Majority in Interest, the Company shall not, and shall not permit any of its Subsidiaries to effect any:

     (i) merger, consolidation or share exchange into or with any other Person, or any other similar business combination transaction (other than any such transaction entered into solely between the Company and any of its Subsidiaries or among any of them) involving the Company or any of its Significant Subsidiaries (as defined in Rule 1-02(w) of Regulation S-X promulgated by the Securities and Exchange Commission, as amended and which shall be deemed to include the MLP) or financial restructuring of the Company, Plains AAP or PAA GP; provided, however, that in the event not all Members receive identical consideration, whether in their capacity as a Member or as a limited partner of Plains AAP, both in form and amount (in proportion to their Membership Interests or Limited Partner Interests, as the case may be) in such transaction, such transaction shall require the prior written consent of any Member receiving consideration that differs from the consideration to be received by a Majority in Interest;

     (ii) voluntary filing for bankruptcy, liquidation, dissolution or winding up of the Company or any of its Subsidiaries or any event that would cause a dissolution or winding up of the Company or any of its Subsidiaries or any consent by the Company or any of its Subsidiaries to any action brought by any other Person relating to any of the foregoing;

     (iii) amendment or repeal of the Certificates, the Plains AAP Partnership Agreement or the PAA GP Agreement; provided, however, that if any amendment to the Plains AAP Partnership Agreement that would, if proposed with respect to this Agreement, require the prior written consent of a particular Member, then such amendment shall require the prior written consent of such Member in its capacity as a limited partner of Plains AAP;

     (iv) sale, lease, transfer, pledge or other disposition of all or substantially all of the properties or assets of the Company or the Company and any of its Subsidiaries taken as a whole, other than sales, leases, transfers, pledges or other dispositions of assets in the ordinary course of business or refinancing of the Credit Agreements; or

     (v) agreement or transaction (or series of related agreements or transactions) between the Company, Plains AAP or PAA GP, on the one hand, and a Member or any of its Affiliates, on the other hand, that involve payments or receipts by the Company or such Subsidiary in excess of $500,000 in the aggregate in any calendar year (but excluding the Administrative Services Agreement between the Company and Vulcan Energy Corporation dated October 14, 2005, other than any amendment thereto that increases or decreases the annual consideration thereunder by more than $500,000);

          (b) Without the prior written consent of a Majority in Interest, the Company shall not, and shall not permit Plains AAP or PAA GP to, effect any:

     (i) except for distributions of Available Cash pursuant to Section 4.1 and distributions pursuant to Section 10.3, and distributions required pursuant to the Plains AAP Partnership Agreement or the PAA GP Agreement (in each case, as amended from time to time in accordance with the terms thereof), declaration or payment of any dividends or other distributions on the Membership Interests, partnership interests or

     (ii) other than equity securities issued upon exercise of convertible or exchangeable securities authorized or outstanding on the date hereof (including 200,000 Class B Units of Plains AAP) or subsequently approved pursuant to this Section 7.9, authorization, sale and/or issuance by the Company, Plains AAP or PAA GP of any of their respective Membership Interests, partnership interests or other equity securities, whether in a private or public offering, including an initial public offering, or the grant, sale or issuance of other securities (including rights, warrants and options) convertible into, exchangeable for or exercisable for any of their respective Membership Interests, partnership interests or other equity securities, whether or not presently convertible, exchangeable or exercisable;

     7.10 Certain Board Rights. (a) Subject to the terms and conditions set forth below, for a period of five years from August 7, 2008 (the “Closing Date”) and provided that (x) Oxy has not disposed of any part of the Membership Interest or Limited Partnership Interest it holds as of the Closing Date in any transaction that is not a Permitted Transfer under clause (c) of the definition thereof and (y) no Change of Control (as defined in the Transaction Agreement) has occurred (collectively, the “Threshold Condition”), (i) Oxy shall have the right to designate an individual (who initially shall be Vicki Sutil, Senior Manager of Corporate Development; any replacement shall also be a senior member of Oxy’s management and acceptable to the Board) (the “Observer”) to receive notice of and attend meetings of the Board in an observer capacity and (ii) upon written request from Oxy and thereafter until Oxy’s rights to designate an Observer terminate or Oxy rescinds such request 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 effect the validity of any action taken by the Board. The terms and conditions of the foregoing provisions are as follows:

     (A) Oxy agrees to treat any and all such information, whether written or oral, as confidential information subject to Section 12.6 hereof;

     (B) In recognition that Oxy 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 LPG or other current or future energy infrastructure related activities that may be deemed to be competitive with the MLP, written materials may be redacted or withheld from Oxy and the Observer if the Board, the Chairman, the Chief Executive Officer or the General Counsel reasonably believes that providing such information could result in the MLP’s competitive positioning being compromised;

     (C) Written materials may be redacted or withheld from Oxy and the Observer if the Board, the Chairman, the Chief Executive Officer or the General Counsel reasonably believe that providing such information (1) would result in a potential breach of the MLP’s confidentiality agreements with third parties; (2) may otherwise disadvantage Plains AAP, GP LLC, the MLP or any of their subsidiaries in ongoing commercial dealings with Oxy or any of its affiliates or (3) is necessary or advisable for the protection and retention of any attorney-client privilege;

     (D) 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 the MLP’s confidentiality agreements with third parties; (2) may otherwise disadvantage Plains AAP, GP LLC, the MLP or any of their subsidiaries in ongoing commercial dealings with Oxy 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 MLP’s competitive positioning being compromised;

     (E) Oxy may eliminate the foregoing restrictions in clauses (B), (C) and (D) above by requesting information or requesting that the 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) adversely affect the retention of any attorney-client privilege or (2) disadvantage Plains AAP, GP LLC, the MLP or any of their subsidiaries in ongoing commercial dealings with Oxy or any of its affiliates;

     (F) Notwithstanding Section 12.6 or Section 13.1 hereof, with respect to materials provided to Oxy pursuant to Section 7.10(a)(B) above or otherwise provided by GP LLC or Plains AAP without solicitation by Oxy, Oxy shall not be presumed to have misused such information solely because the Oxy representative may have retained a mental impression of such information in connection with Oxy’s participation in activities competitive with GP LLC, Plains AAP or the MLP. This Section 7.10(a)(F) shall not apply with respect to information provided to Oxy pursuant to Section 7.10(a)(E) above or otherwise provided upon Oxy’s request; and

     (G) The Observer shall not have any voting rights. No consent or approval of the Observer shall be required for any action taken by the Board. The attendance or participation of the Observer at a meeting shall not be required for action by the Board.

     (b) If, within five years from the Closing Date, a Triggering Event occurs, then if Oxy meets the Threshold Condition, (i) Section 7.1(a)(i) hereof shall be deemed to be amended to provide that (A) the Board shall thereafter consist of nine (9) Directors and (B) subject to Section 7.1(a)(iv) hereof, Oxy shall be entitled to designate one (1) Director; (ii) each Member agrees to take all actions necessary to add Oxy’s designee to the Board as soon as practicable after such Triggering Event; (iii) Section 7.1(a)(iv) hereof shall be deemed to be amended to provide that Oxy shall have the right to designate a Director pursuant to Section 7.1(a)(i)(A) so long as it meets the Threshold Condition; and (iv) Oxy’s rights to designate an Observer set forth in clause (a) above shall terminate.

     7.11 Registration Rights. (a) In connection with any Initial Public Offering by the Company, Plains AAP or any Person that directly or indirectly owns the MLP’s general partner interest or Incentive Distribution Rights (as defined in the MLP Partnership Agreement) (the Company, Plains AAP or any such other Person, the “IPO Issuer”), the Company shall cause the IPO Issuer to grant to the Members at such time Customary Registration Rights in respect of any securities held or received by such Members that are of the same type that are offered in such registered public offering.

     (b) For purposes of this Section 7.11, (i) “Initial Public Offering” means any firm commitment underwritten initial public offering by the IPO Issuer of equity securities pursuant to an effective registration statement under the Securities Act of 1933, as amended, after which such equity securities are authorized and approved for listing on a National Securities Exchange; (ii) “National Securities Exchange” means an exchange registered with the Securities and Exchange Commission under Section 6(a) of the Securities Exchange Act of 1934, as amended, and any successor to such statute; and (iii) “Customary Registration Rights” means (A) pro rata participation by the Members in the Initial Public Offering to the extent secondary sales of securities held by the Members are included in such offering, (B) participation by the Members (subject to allocation) in any demand registration for the benefit of the Members following completion of the Initial Public Offering, (C) inclusion of securities for sale in a shelf registration statement for the benefit of the Members to be filed on Form S-3 following completion of the Initial Public Offering and (D) “piggyback” participation rights on any firm commitment underwritten offering by the IPO Issuer following completion of the Initial Public Offering; provided, however, that the registration rights described in (B), (C), and (D) will be contained in a registration rights agreement to be entered into by the Members in conjunction with the Initial Public Offering that will include provisions with respect to participation and allocation of sales rights among the Members for underwritten offerings, cut-back rights in favor of the underwriters and the IPO Issuer, black-out rights in favor of the IPO Issuer, lock-up requirements and indemnification and other such provisions as are typically included in registration rights agreements. Notwithstanding the foregoing, in the case of Oxy, so long as it meets the Threshold Condition, Customary Registration Rights must include (1) if Oxy’s Percentage Interest is the second largest Percentage Interest of all Members, one demand registration right exercisable by Oxy and no less favorable participation and allocation rights and protection from cut-back rights than those received by Members with smaller Percentage Interests and (2) if

Oxy’s Percentage Interest is not the second largest Percentage Interest of all Members, no less favorable demand registration rights and participation and allocation rights and protection from cut-back rights than those received by the Member that has the second largest Percentage Interest of all Members.

ARTICLE 8
LIABILITY AND INDEMNIFICATION

     8.1 Limitation on Liability of Members, Directors and Officers. No Member (when not acting in violation of this Agreement or applicable law), Director or Officer shall have any liability to the Company or the Members for any losses sustained or liabilities incurred as a result of any act or omission of such Member, Director or Officer in connection with the conduct of the business of the Company if, in the case of an Officer, the Officer acted in a manner he or she reasonably believed to be in, or not opposed to, the interests of the Company or applicable law and to be within the scope of his or her authority and, in the case of a Member (when not acting in violation of this Agreement or applicable law), Director or Officer, the conduct did not constitute bad faith, fraud, gross negligence or willful misconduct. To the fullest extent permitted by Section 18-1101(c) of the Act, a Director (other than Independent Directors), in performing his or her obligations under this Agreement, shall be entitled to act or omit to act at the direction of the Member who designated such Director, considering only such factors, including the separate interests of the designating Member, as such Director or the 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 8.1 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 any other Member or 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 Officer, Member or Director shall be personally responsible for any such debt, obligation or liability of the Company solely by reason of being an Officer, Member or Director. No Member shall be responsible for any debts, obligations or liabilities, whether arising in contract, tort or otherwise, of any other Member.

     8.2 Indemnification.

     (a) The Company shall indemnify and hold harmless the Members (when not acting in violation of this Agreement or applicable law), Directors and Officers (each, a “Company Affiliate”) 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 a Company Affiliate may be involved, or threatened to be involved, as a party or otherwise, by reason of his, her or its status as a Company Affiliate, regardless of whether a Company Affiliate continues to be a Company Affiliate at the time any such liability or expense is paid or incurred, if such Company Affiliate acted in good faith and in a manner he or she reasonably 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 a Company Affiliate in defending any claim, demand, action, suit or proceeding subject to Section 8.2(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 Company Affiliate to repay such amounts if it is ultimately determined that the Company Affiliate is not entitled to be indemnified as authorized in this Section 8.2.

     (c) The indemnification provided by this Section 8.2 shall be in addition to any other rights to which a Company Affiliate may be entitled pursuant to any approval of a Majority in Interest, as a matter of law or equity, or otherwise, and shall continue as to a Company Affiliate who has ceased to serve in such capacity and shall inure to the benefit of the heirs, successors, assigns, and administrators of such Company Affiliate; provided, however, that in the event such Company Affiliate is also an Affiliate of a Member, such Member’s Percentage Interest shall be disregarded for purposes of determining a Majority in Interest for purposes of this Section 8.2(c). The Company shall not be required to indemnify any Member in connection with any losses, claims, demands, actions, disputes, suits or proceedings, of any Member against any other Member.

     (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 in the sole discretion of the Board.

     (e) Any indemnification hereunder shall be satisfied only out of the assets of the Company, and the Members shall not be subject to personal liability by reason of the indemnification provisions under this Section 8.2.

     (f) A Company Affiliate shall not be denied indemnification in whole or in part under this Section 8.2 because the Company Affiliate 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 8.2(c), the provisions of this Section 8.2 are for the benefit of the Company Affiliates and the heirs, successors, assigns and administrators of the Company Affiliates and shall not be deemed to create any rights for the benefit of any other Persons.

     (h) Any repeal or amendment of any provisions of this Section 8.2 shall be prospective only and shall not adversely affect any Company Affiliates’ rights existing at the time of such repeal or amendment.

ARTICLE 9
TRANSFERS OF MEMBERSHIP INTERESTS

     9.1 General Restrictions.

     (a) No Member may Transfer all or any part of such Member’s Membership Interest to any Person except (i) to a Permitted Transferee pursuant to Section 9.2 or (ii) pursuant to the terms of Section 9.8; provided, however, any such Transfer under (i) or (ii) above shall comply

with the terms of Section 9.1(b). Any purported Transfer of a Membership Interest or a portion thereof in violation of the terms of this Agreement shall be null and void and of no force and effect. Except upon a Transfer of all of a Member’s Membership Interest in accordance with this Section 9.1, no Member shall have the right to withdraw as a Member of the Company.

     (b) As a condition to a Transfer by a Member of all or any part of such Member’s Membership Interest to a transferee as permitted under Section 9.1(a)(i) or (ii), (a “Membership Transfer”), such Member shall simultaneously Transfer (the “Plains AAP Transfer”) to such transferee an amount of such Member’s Limited Partnership Interest equal to: (i) such Member’s Limited Partnership Interest, multiplied by (ii) a percentage equal to (1) the Percentage Interest of such Member to be Transferred to such transferee, divided by (2) such Member’s Percentage Interest immediately before such Transfer. If for any reason Plains AAP Transfer does not occur simultaneously with the Membership Transfer, then the Membership Transfer and Plains AAP Transfer shall be null and void and of no force and effect.

     (c) Notwithstanding any other provision of this Agreement, no Member may pledge, mortgage or otherwise subject its Member Interest to any Encumbrance.

     9.2 Permitted Transferees.

     (a) Notwithstanding the provisions of Section 9.8, each Member shall, subject to Section 9.1(b), have the right to Transfer (but not to substitute the transferee as a substitute Member in such Member’s place, except in accordance with Section 9.3), by a written instrument, all or any part of a Member’s Membership Interest to a Permitted Transferee. Notwithstanding the previous sentence, if the Permitted Transferee is such because it was an Affiliate of the transferring Member at the time of such Transfer or the Transfer was a Permitted Transfer under clause (a) of the definition of Permitted Transfer and, at any time after such Transfer, such Permitted Transferee ceases to be an Affiliate of such Member or such Transfer or such Permitted Transferee ceases to qualify under such clause (a) (a “Non-Qualifying Transferee”), such Transfer shall be deemed to not be a Permitted Transfer and shall be subject to Section 9.8. Pursuant to Section 9.8, such transferring Member, or such transferring Member’s legal representative, shall deliver the First Refusal Notice promptly after the time when such transferee ceases to be an Affiliate of such transferring Member, or such Transfer or such Permitted Transferee ceases to qualify under clause (a) of the definition of Permitted Transfer, and such transferring Member shall otherwise comply with the terms of Section 9.8 with respect to such Transfer; provided, that the purchase price for such Transfer for purposes of Section 9.8 shall be an amount agreed upon by such transferring Member and a Majority in Interest (excluding such transferring Member’s Percentage Interest) or, if such Member and such Majority in Interest cannot agree on a price within five (5) Business Days after delivery of the First Refusal Notice, such price shall be the fair market value of the Membership Interest transferred pursuant to the Transfer as of the date the transferee ceased to be an Affiliate of such transferring Member or such Transfer or such Permitted Transferee ceases to qualify under clause (a) of the definition of Permitted Transfer (such date, the “Non-Qualifying Date”), as determined at the Company’s expense by a nationally recognized investment banking firm mutually selected by such transferring Member and a Majority in Interest (excluding such transferring Member’s Percentage Interest). If such transferring Member and such Majority in Interest are unable, within ten (10) days after the expiration of such five (5) Business Day period,

to mutually agree upon an investment banking firm, then each of such transferring Member and such Majority in Interest shall choose a nationally recognized investment banking firm and the two investment banking firms so chosen shall choose a third nationally recognized investment banking firm which shall determine the fair market value of the Membership Interest transferred pursuant to such Transfer at the Company’s expense. The determination of fair market value shall be based on the value that a willing buyer with knowledge of all relevant facts would pay a willing seller for all the outstanding equity securities of the Company in connection with an auction for the Company as a going concern and shall not take into account any acquisitions made by the Company or its Affiliates or any other events subsequent to the Non-Qualifying Date and shall not be subject to any discount for a sale of a minority interest. If such transferring Member fails to comply with all the terms of Section 9.8, such Transfer shall be null and void and of no force and effect. No Non-Qualifying Transferee shall be entitled to receive any distributions from the Company on or after the Non-Qualifying Date and any distributions made in respect of the Membership Interests on or after the Non-Qualifying Date and held by such Non-Qualifying Members shall be paid to the Member who transferred such Membership Interest or otherwise to the rightful owner thereof as reasonably determined by the Board.

     (b) Unless and until admitted as a substitute Member pursuant to Section 9.3, a transferee of a Member’s Membership Interest in whole or in part shall be an assignee with respect to such Transferred Membership Interest and shall not be entitled to participate in the management of the business and affairs of the Company or to become, or to exercise the rights of, a Member, including the right to appoint Directors, the right to vote, the right to require any information or accounting of the Company’s business, or the right to inspect the Company’s books and records. Such transferee shall only be entitled to receive, to the extent of the Membership Interest Transferred to such transferee, the share of distributions and profits, including distributions representing the return of Capital Contributions, to which the transferor would otherwise be entitled with respect to the Transferred Membership Interest. The transferor shall have the right to vote such Transferred Membership Interest until the transferee is admitted to the Company as a substitute Member with respect to the Transferred Membership Interest.

     9.3 Substitute Members. No transferee of all or part of a Member’s Membership Interest shall become a substitute Member in place of the transferor unless and until:

     (a) Such Transfer is in compliance with the terms of Section 9.1;

     (b) the transferee has executed an instrument in form and substance reasonably satisfactory to the Board accepting and adopting, and agreeing to be bound by, the terms and provisions of the Certificate of Formation of the Company and this Agreement; and

     (c) the transferee has caused to be paid all reasonable expenses of the Company in connection with the admission of the transferee as a substitute Member.

Upon satisfaction of all the foregoing conditions with respect to a particular transferee, the books and records of the Company shall be adjusted to reflect the admission of the transferee as a substitute Member to the extent of the Transferred Membership Interest held by such transferee.

     9.4 Effect of Admission as a Substitute Member. A transferee who has become a substitute Member has, to the extent of the Transferred Membership Interest, all the rights, powers and benefits of, and is subject to the obligations, restrictions and liabilities of a Member under, the Certificate of Formation of the Company, this Agreement and the Act. Upon admission of a transferee as a substitute Member, the transferor of the Membership Interest so held by the substitute Member shall cease to be a Member of the Company to the extent of such Transferred Membership Interest.

     9.5 Consent. Each Member hereby agrees that upon satisfaction of the terms and conditions of this Article 9 with respect to any proposed Transfer, the transferee may be admitted as a Member without any further action by a Member hereunder.

     9.6 No Dissolution. If a Member Transfers all of its Membership Interest pursuant to this Article 9 and the transferee of such Membership Interest is admitted as a Member pursuant to Section 9.3, such Person shall be admitted to the Company as a Member effective on the effective date of the Transfer and the Company shall not dissolve pursuant to Section 10.1.

     9.7 Additional Members. Subject to Section 3.2 and Section 7.9, any Person acceptable to the Board may become an additional Member of the Company for such consideration as the Board shall determine, provided that such additional Member complies with all the requirements of a transferee under Section 9.3(b) and (c).

     9.8 Right of First Refusal. The Members shall have the following right of first refusal:

     (a) If at any time any of the Members (a “Selling Member”) has received and wishes to accept a bona fide offer (the “Offer”) for cash from a third party (the “Offeror”) for all or part of such Selling Member’s Membership Interest (and a proportionate amount of such Selling Member’s Limited Partnership Interest in accordance with Section 9.1(b)), such Selling Member shall give Notice thereof (the “First Refusal Notice”) to each of the other Members, other than any Non-Purchasing Members (as hereinafter defined), and the Company. The First Refusal Notice shall state the portion of the Selling Member’s Membership Interest and Limited Partnership Interest that the Selling Member wishes to sell (the “Optioned Interest”), the price and all other material terms of the Offer, the name of the Offeror, and certification from the Selling Member affirming that the Offer is bona fide and that the description thereof is true and correct, and that the Offeror has stated that it will purchase the Optioned Interest if the rights of first refusal herein described are not exercised.

     (b) Each of the Members other than the Selling Member and any Non-Purchasing Member (the “Non-Selling Members”) shall have the right exercisable by Notice (an “Acceptance Notice”) given to the Selling Member and the Company within twenty (20) days after receipt of the First Refusal Notice, to agree that it will purchase up to 100% of the Optioned Interest on the terms set forth in the First Refusal Notice; provided, however, if the Non-Selling Members in the aggregate desire to purchase more than 100% of the Optioned Interest, each such Non-Selling Member’s right to purchase the Optioned Interest shall be reduced (pro rata based on the percentage of Optioned Interest for which such Non-Selling Member has exercised its right to purchase hereunder compared to all other Non-Selling Members, but not below such Non-

Selling Member’s Membership Interest as a percentage of the aggregate Membership Interests of all Non-Selling Members who have exercised their right to purchase) so that such Non-Selling Members purchase no more than 100% of the Optioned Interest. If a Non-Selling Member does not submit an Acceptance Notice within the twenty (20) day period set forth in this Section 9.8(b), such Non-Selling Member shall be deemed to have rejected the offer to purchase any portion of the Optioned Interest.

     (c) If the Non-Selling Members do not in the aggregate exercise the right to purchase all of the Optioned Interest by the expiration of the twenty (20) day period set forth in Section 9.8(b), then any Acceptance Notice shall be void and of no effect, and the Selling Member shall be entitled to complete the proposed sale at any time in the thirty (30) day period commencing on the date of the First Refusal Notice, but only upon the terms set forth in the First Refusal Notice. If no such sale is completed in such thirty (30) day period, the provisions hereof shall apply again to any proposed sale of the Optioned Interest.

     (d) If any Non-Selling Member exercises the right to purchase the Optioned Interest as provided herein and such Non-Selling Member(s) have elected to purchase all of the Optioned Interest, the purchase of such Optioned Interest shall be completed within the thirty (30) day period commencing on the date of delivery of the First Refusal Notice. If such Non-Selling Member does not consummate the Purchase of such Optioned Interest, (x) the Selling Member shall be entitled to all expenses of collection and (y) such Non-Selling Member shall be deemed a “Non-Purchasing Member” for the duration of this Agreement.

ARTICLE 10
DISSOLUTION AND TERMINATION

     10.1 Events Causing Dissolution.

     (a) The Company shall be dissolved and its affairs wound up upon the first to occur of the following events:

     (i) The affirmative vote of a Super Majority in Interest to dissolve;

     (ii) The Transfer of all or substantially all of the assets of the Company and the receipt and distribution of all the proceeds therefrom; or

     (iii) The entry of a decree of judicial dissolution pursuant to Section 18-802 of the Act.

     (b) The withdrawal, death, retirement, resignation, expulsion, bankruptcy or dissolution of any Member or the occurrence of any other event that terminates the continued membership of any Member in the Company shall not, in and of itself, cause the Company’s dissolution.

     10.2 Final Accounting. Upon dissolution and winding up of the Company, an accounting will be made of the accounts of the Company and each Member and of the Company’s assets, liabilities and operations from the date of the last previous accounting to the date of such dissolution.

     10.3 Distributions Following Dissolution and Termination.

     (a) Liquidating Trustee. Upon the dissolution of the Company, such party as is designated by a Majority in Interest will act as liquidating trustee of the Company (the “Liquidating Trustee”) and proceed to wind up the business and affairs of the Company in accordance with the terms of this Agreement and applicable law. The Liquidating Trustee will use its reasonable best efforts to sell all Company assets (except cash) in the exercise of its best judgment under the circumstances then presented, that it deems in the best interest of the Members. The Liquidating Trustee will attempt to convert all assets of the Company to cash so long as it can do so consistently with prudent business practice. The Members and their respective designees will have the right to purchase any Company property to be sold on liquidation, provided that the terms on which such sale is made are no less favorable than would otherwise be available from third parties. The gains and losses from the sale of the Company assets, together with all other revenue, income, gain, deduction, expense, loss and credit during the period, will be allocated in accordance with Article 5. A reasonable amount of time shall be allowed for the period of winding up in light of prevailing market conditions and so as to avoid undue loss in connection with any sale of Company assets. This Agreement shall remain in full force and effect during the period of winding up. In addition, upon request of the Board and if the Liquidating Trustee determines that it would be imprudent to dispose of any non-cash assets of the Company, such assets may be distributed in kind to the Members in lieu of cash, proportionately to their right to receive cash distributions hereunder.

     (b) Accounting. The Liquidating Trustee will then cause proper accounting to be made of the Capital Account of each Member, including recognition of gain or loss on any asset to be distributed in kind as if such asset had been sold for consideration equal to the fair market value of the asset at the time of the distribution. The Members intend that the allocations provided herein shall result in Capital Account balances in proportion to the Percentage Interests of the Members.

     (c) Liquidating Distributions. In settling accounts after dissolution of the Company, the assets of the Company shall be paid to creditors of the Company and to the Members in the following order:

     (i) to creditors of the Company (including Members) in the order of priority as provided by law whether by payment or the making of reasonable provision for payment thereof, and in connection therewith there shall be withheld such reasonable reserves for contingent, conditioned or unconditioned liabilities as the Liquidating Trustee in its reasonable discretion deems adequate, such reserves (or balances thereof) to be held and distributed in such manner and at such times as the Liquidating Trustee, in its discretion, deems reasonably advisable; provided, however, that such amounts be maintained in a separate bank account and that any amounts in such bank account remaining after three years be distributed to the Members or their successors and assigns as if such amount had been available for distribution under Section 10.3(c)(ii); and then

     (ii) to the Members in proportion to the positive balances of their Capital Accounts, as fully adjusted pursuant to Section 3.4, including adjustment for all gains and

losses actually or deemed realized upon disposition or distribution of assets in connection with the liquidation and winding up of the Company.

     (iii) Any distribution to the Members in liquidation of the Company shall be made by the later of the end of the taxable year in which the liquidation occurs or 90 days after the date of such liquidation. For purposes of the preceding sentence, the term “liquidation” shall have the same meaning as set forth in Regulation Section 1.704-1(b)(2)(ii) as in effect at such time and liquidating distributions shall be further deemed to be made pursuant to this Agreement upon the event of a liquidation as defined in such Regulation for which no actual liquidation occurs with a deemed recontribution by the Members of such deemed liquidating distributions to the continuing Company pursuant to this Agreement.

     (d) The provisions of this Agreement, including, without limitation, this Section 10.3, are intended solely to benefit the Members and, to the fullest extent permitted by law, shall not be construed as conferring any benefit upon any creditor of the Company, and no such creditor of the Company shall be a third-party beneficiary of this Agreement, and no Member or Director shall have any duty or obligation to any creditor of the Company to issue any call for capital pursuant to this Agreement.

     10.4 Termination of the Company.

Therefore, notwithstanding any other provision of this Article V (other than the Regulatory Allocations), the General Partner shall make such offsetting special allocations of income, gain, loss or deduction in whatever manner it determines appropriate so that, after such offsetting allocations are made, each Partner’s Capital Account balance is, to the extent possible, equal to the Capital Account balance such Partner would have had if the Regulatory Allocations were not part of this Agreement and all such items were allocated pursuant to Sections 5.1, 5.2 and 5.3 without regard to the Regulatory Allocations.

     (d) Contributed Units Special Allocations. Notwithstanding any other provision of this Agreement, but subject to Section 5.5, all income, gain, loss and deduction related to the Contributed Units shall be allocated to the Partners in proportion to their relative Unit Percentages.

5.5 Tax Allocations: Code Section 704(c)

     (a) Except as otherwise provided herein, for federal income tax purposes, (i) each item of income, gain, loss and deduction shall be allocated among the Partners in the same manner as its correlative item of “book” income, gain, loss or deduction is allocated pursuant to Sections 5.1

and 5.2, and (ii) each tax credit shall be allocated to the Partners in the same manner as the receipt or expenditure giving rise to such credit is allocated pursuant to Section 5.1 or 5.2.

     (b) In accordance with Code Section 704(c) and the Regulations thereunder, income, gain, loss and deduction with respect to any Property contributed to the capital of the Partnership shall, solely for tax purposes, be allocated among the Partners so as to take account of any variation between the adjusted basis of such Property to the Partnership for federal income tax purposes and its initial Gross Asset Value (computed in accordance with the definition herein of “Gross Asset Value”).

     (c) In the event the Gross Asset Value of any Partnership asset is adjusted pursuant to subparagraph (b) of the definition herein of “Gross Asset Value”, subsequent allocations of income, gain, loss and deduction with respect to such asset shall take account of any variation between the adjusted basis of such asset for federal income tax purposes and its Gross Asset Value in the same manner as under Code Section 704(c) and the Regulations thereunder.

     (d) Any elections or other decisions relating to such allocations shall be made by the General Partner in any manner that reasonably reflects the purpose and intention of this Agreement; provided, that the Partnership, in the discretion of the General Partner, may make, or not make, “curative” or “remedial” allocations (within the meaning of the Regulations under Code Section 704(c)) including, but not limited to, “curative” allocations which offset the effect of the “ceiling rule” for a prior Taxable Year (within the meaning of Regulation Section 1.704-3(c)(3)(ii)) and “curative” allocations from disposition of contributed property (within the meaning of Regulation Section 1.704-3(c)(3)(iii)(B)). Allocations pursuant to this Section 5.5 are solely for purposes of federal, state, and local taxes and shall not affect, or in any way be taken into account in computing, any Partner’s Capital Account or share of Profits, Losses, other items, or distributions pursuant to any provision of this Agreement.

5.6 Change in Partnership Interest

     In the event that the Partners’ interests in the Partnership change during a Taxable Year, allocations shall be made taking into account the Partners’ varying interests for such Taxable Year, determined on a daily, monthly or other basis as determined by the General Partner, using any permissible method under Code Section 706 and the Regulations thereunder.

5.7 Withholding

     Each Partner hereby authorizes the Partnership to withhold from income or distributions allocable to such Partner and to pay over any taxes payable by the Partnership or any of its Affiliates as a result of such Partner’s participation in the Partnership; if and to the extent that the Partnership shall be required to withhold any such taxes, such Partner shall be deemed for all purposes of this Agreement to have received a distribution from the Partnership as of the time such withholding is required to be paid, which distribution shall be deemed to be a distribution to such Partner to the extent that the Partner is then entitled to receive a distribution. To the extent that the aggregate of such distributions in respect of a Partner for any period exceeds the distributions to which such Partner is entitled for such period, the amount of such excess shall be considered a demand loan from the Partnership to such Partner, with interest at the rate of

interest per annum that Citibank, N.A., or any successor entity thereto, announces from time to time as its prime lending rate, which interest shall be treated as an item of Partnership income, until discharged by such Partner by repayment, which may be made in the sole discretion of the General Partner out of distributions to which such Partner would otherwise be subsequently entitled. The withholdings referred to in this Section 5.7 shall be made at the maximum applicable statutory rate under applicable tax law unless the General Partner shall have received an opinion of counsel or other evidence, satisfactory to the General Partner, to the effect that a lower rate is applicable, or that no withholding is applicable.

ARTICLE VI

The Partners acknowledge that such proxy is coupled with an interest and is irrevocable.

     (c) The General Partner is the tax matters partner for purposes of Section 6231 of the Code and analogous provisions of state law.

6.4 Rights of Limited Partners

     The Limited Partners will not be personally liable for any obligations of the Partnership nor will they have any obligation to make contributions to the Partnership in excess of their respective Capital Contributions required under Section 3.1 or have any liability for the repayment or discharge of the debts and obligations of the Partnership except to the extent provided herein or as required by law. The Limited Partners in their capacities as such shall take no part in the management, control or operation of the Partnership’s business and shall have no power to bind the Partnership and no right or authority to act for the Partnership or to vote on matters other than the matters set forth in this Agreement or as required by applicable law.

Proceeds of any other disposition of Contributed Units may be disbursed at the discretion of the General Partner.

ARTICLE VII
TRANSFERS OF PARTNERSHIP INTERESTS

7.1 Transfer of Limited Partnership Interests

     (a) No Limited Partner may Transfer all or any part of such Partner’s Partnership Interest to any Person except (i) to a Permitted Transferee pursuant to Section 7.2, or (ii) pursuant to the terms of Section 7.8; provided, however, any such Transfer under (i) or (ii) above shall comply with the terms of Section 7.1(b). Any purported Transfer of a Partnership Interest or a portion

thereof in violation of the terms of this Agreement shall be null and void and of no force and effect. Except upon a Transfer of all of a Limited Partner’s Partnership Interest in accordance with Section 7.1, no Limited Partner shall have the right to withdraw as a Partner of the Partnership.

     (b) As a condition to a Transfer by a Class A Partner of all or any part of such Partner’s Partnership Interest to a transferee as permitted under Section 7.1(a)(i) or (ii) (a “Partnership Transfer”), such Partner shall simultaneously Transfer (the “Membership Transfer”) to such transferee an amount of such Partner’s Membership Interest equal to: (i) such Partner’s Membership Interest, multiplied by (ii) a percentage equal to (1) the portion of such Partner’s Partnership Interest (as evidenced by Class A Units) to be Transferred to such transferee, divided by (2) such Partner’s Partnership Interest (as evidenced by Class A Units) immediately before such Transfer. Similarly, in connection with any Partnership Transfer, such Partner shall simultaneously transfer (the “Unit Percentage Transfer”) a proportionate share of such Partner’s Unit Percentage. If for any reason the Membership Transfer and Unit Percentage Transfer does not occur simultaneously with the Partnership Transfer, then the Partnership Transfer shall be null and void and of no force and effect.

     (c) Notwithstanding any other provision of this Agreement, no Limited Partner may pledge, mortgage or otherwise subject its Limited Partnership Interest to any Encumbrance.

7.2 Permitted Transferees

     (a) Notwithstanding the provisions of Section 7.8, each Limited Partner shall, subject to Section 7.1(b), have the right to Transfer (but not to substitute the transferee as a substitute Partner in such Partner’s place, except in accordance with Section 7.3), by a written instrument, all or any part of a Limited Partner’s Partnership Interest to a Permitted Transferee. Notwithstanding the previous sentence, if the Permitted Transferee is such because it was an Affiliate of the transferring Limited Partner at the time of such Transfer or the Transfer was a Permitted Transfer under clause (a) of the definition herein of “Permitted Transfer” and, at any time after such Transfer, such Permitted Transferee ceases to be an Affiliate of such Limited Partner or such Transfer or such Permitted Transferee ceases to qualify under such clause (a) (a “Non-Qualifying Transferee”), such Transfer shall be deemed to not be a Permitted Transfer and shall be subject to Section 7.8. Pursuant to Section 7.8, such transferring Limited Partner or such transferring Limited Partner’s legal representative shall deliver the First Refusal Notice promptly after the time when such transferee ceases to be an Affiliate of such transferring Limited Partner or such Transfer or such Permitted Transferee ceases to qualify under clause (a) of the definition herein of “Permitted Transfer”, and such transferring Limited Partner shall otherwise comply with the terms of Section 7.8 with respect to such Transfer; provided, that the purchase price for such Transfer for purposes of Section 7.8 shall be an amount agreed upon by such transferring Limited Partner and the General Partner or, if such Limited Partner and the General Partner cannot agree on a price within five (5) Business Days after delivery of the First Refusal Notice, such price shall be the fair market value of the Partnership Interest transferred pursuant to the Transfer as of the date the transferee ceased to be an Affiliate of such transferring Limited Partner or such Transfer or such Permitted Transferee ceases to qualify under clause (a) of the definition herein of “Permitted Transfer” (such date, the “Non-Qualifying Date”), as determined at the Partnership’s expense by a nationally recognized investment banking firm

mutually selected by such transferring Limited Partner and the General Partner. If such transferring Limited Partner and the General Partner are unable, within ten (10) days after the expiration of such five (5) Business Day period, to mutually agree upon an investment banking firm, then each of such transferring Limited Partner and the General Partner shall choose a nationally recognized investment banking firm and the two investment banking firms so chosen shall choose a third nationally recognized investment banking firm which shall determine the fair market value of the Partnership Interest transferred pursuant to such Transfer at the Partnership’s expense. The determination of fair market value shall be based on the value that a willing buyer with knowledge of all relevant facts would pay a willing seller for all the outstanding equity securities of the Partnership in connection with an auction for the Partnership as a going concern and shall not take into account any acquisitions made by the Partnership or its Affiliates or any other events subsequent to the Non-Qualifying Date and shall not be subject to any discount for a sale of a minority interest. If such transferring Limited Partner fails to comply with all the terms of Section 7.8, such Transfer shall be null and void and of no force and effect. No Non-Qualifying Transferee shall be entitled to receive any distributions from the Partnership on or after the Non-Qualifying Date and any distributions made in respect of the Partnership Interests on or after the Non-Qualifying Date and held by such Non-Qualifying Transferee shall be paid to the Limited Partner who transferred such Partnership Interests or otherwise to the rightful owner thereof as reasonably, determined by the General Partner.

     (b) Unless and until admitted as a substitute Limited Partner pursuant to Section 7.3, a transferee of a Limited Partner’s Partnership Interest, in whole or in part, shall be an assignee with respect to such Transferred Partnership Interest and shall not be entitled to become, or to exercise the rights of, a Limited Partner, including the right to vote, the right to require any information or accounting of the Partnership’s business, or the right to inspect the Partnership’s books and records. Such transferee shall only be entitled to receive, to the extent of the Partnership Interest Transferred to such transferee, the share of distributions and profits, including distributions representing the return of Capital Contributions, to which the transferor would otherwise be entitled with respect to the Transferred Partnership Interest. Subject to the provisions of Section 6.1(b), the transferor shall have the right to vote such Transferred Partnership Interest until the transferee is admitted to the Partnership as a substitute Limited Partner with respect to the Transferred Partnership Interest.

7.3 Substitute Limited Partners

     No transferee of all or part of a Limited Partner’s Partnership Interest shall become a substitute Limited Partner in place of the transferor unless and until:

     (a) such Transfer is in compliance with the terms of Section 7.1;

     (b) the transferee has executed an instrument in form and substance reasonably satisfactory to the General Partner accepting and adopting, and agreeing to be bound by, the terms and provisions of the Certificate and this Agreement; and

     (c) the transferee has caused to be paid all reasonable expenses of the Partnership in connection with the admission of the transferee as a substitute Limited Partner.

     Upon satisfaction of all the foregoing conditions with respect to a particular transferee, the General Partner shall cause the books and records of the Partnership to reflect the admission of the transferee as a substitute Limited Partner to the extent of the Transferred Partnership Interest held by such transferee.

7.4 Effect of Admission as a Substitute Limited Partner

     A transferee who has become a substitute Limited Partner has, to the extent of the Transferred Partnership Interest, all the rights, powers and benefits of, and is subject to the obligations, restrictions and liabilities of a Partner under, the Certificate, this Agreement and the Act. Upon admission of a transferee as a substitute Limited Partner, the transferor of the Partnership Interest so held by the substitute Limited Partner shall cease to be a Partner of the Partnership to the extent of such Transferred Partnership Interest.

7.5 Consent

     Each Partner hereby agrees that upon satisfaction of the terms and conditions of this Article VII with respect to any proposed Transfer, the transferee may be admitted as a Partner without any further action by a Partner hereunder.

7.6 No Dissolution

     If a Limited Partner Transfers all of its Partnership Interest pursuant to this Article VII and the transferee of such Partnership Interest is admitted as a Limited Partner pursuant to Section 7.3, such Person shall be admitted to the Partnership as a Partner effective on the effective date of the Transfer and the Partnership shall not dissolve pursuant to Section 8.1.

7.7 Additional Limited Partners

     Subject to Section 3.2, any Person acceptable to the General Partner may become an additional Limited Partner of the Partnership for such consideration as the General Partner shall determine, provided that such additional Limited Partner complies with all the requirements of a transferee under Section 7.3(b) and (c).

7.8 Right of First Refusal

     The Class A Partners shall have the following right of first refusal:

     (a) If at any time any of the Class A Partners (a “Selling Partner”) has received and wishes to accept a bona fide offer (the “Offer”) for cash from a third party (the “Offeror”) for all or part of such Selling Partner’s Partnership Interest (and a proportionate amount of such Selling Partner’s Membership Interest and Unit Percentage in accordance with Section 7.1(b)), such Selling Partner shall give Notice thereof (the “First Refusal Notice”) to each of the other Partners, other than any Non-Purchasing Partners (as hereinafter defined) and any Class B Partners, and the Partnership. The First Refusal Notice shall state the portion of the Selling Partner’s Partnership Interest and Membership Interest that the Selling Partner wishes to sell (the “Optioned Interest”), the price and all other material terms of the Offer, the name of the Offeror, and certification from the Selling Partner affirming that the Offer is bona fide and that the

description thereof is true and correct, and that the Offeror has stated that it will purchase the Optioned Interest if the rights of first refusal herein described are not exercised.

     (b) Each of the Class A Partners other than the Selling Partner, any Non-Purchasing Partner (the “Non-Selling Partner”) shall have the right exercisable by Notice (an “Acceptance Notice”) given to the Selling Partner and the Partnership within twenty (20) days after receipt of the First Refusal Notice, to agree that it will purchase up to 100% of the Optioned Interest on the terms set forth in the First Refusal Notice; provided, however, if the Non-Selling Partners in the aggregate desire to purchase more than 100% of the Optioned Interest, each such Non-Selling Partner’s right to purchase the Optioned Interest shall be reduced (pro rata based on the percentage of the Optioned Interest for which such Non-Selling Partner has exercised its right to purchase hereunder compared to all other Non-Selling Partners, but not below such Non-Selling Partner’s pro rata share (based on the number of Class A Units held by such Non-Selling Partner and the aggregate number of Class A Units held by all Non-Selling Partners who have exercised their right to purchase) so that such Non-Selling Partners purchase no more than 100% of the Optioned Interest. If a Non-Selling Partner does not submit an Acceptance Notice within the twenty (20) day period set forth in this Section 7.8(b), such Non-Selling Partner shall be deemed to have rejected the offer to purchase any portion of the Optioned Interest.

     (c) If the Non-Selling Partners do not in the aggregate exercise the right to purchase all of the Optioned Interest by the expiration of the twenty (20) day period set forth in Section 7.8(b), then any Acceptance Notice shall be void and of no effect, and the Selling Partner shall be entitled to complete the proposed sale at any time in the thirty (30) day period commencing on the date of the First Refusal Notice, but only upon the terms set forth in the First Refusal Notice. If no such sale is completed in such thirty (30) day period, the provisions hereof shall apply again to any proposed sale of the Optioned Interest.

     (d) If any Non-Selling Partner exercises the right to purchase the Optioned Interest as provided herein and such Non-Selling Partner(s) have elected to purchase all of the Optioned Interest, the purchase of such Optioned Interest shall be completed within the thirty (30) day period commencing on the date of delivery of the First Refusal Notice on the terms set forth in the First Refusal Notice. If such Non-Selling Partner does not consummate the Purchase of such Optioned Interest, (x) the Selling Partner shall be entitled to all expenses of collection and (y) such Non-Selling Partner shall be deemed a “Non-Purchasing Partner” for the duration of this Agreement.

     (e) Notwithstanding anything in this Agreement to the contrary, no Class B Partner in its capacity as such shall have any right to Transfer any Class B Units or to purchase any Class A Units pursuant to this Section 7.8.

ARTICLE VIII
DISSOLUTION AND LIQUIDATION

8.1 Dissolution of Partnership

     (a) The Partnership shall be dissolved and its affairs wound up upon the first to occur of the following events:

	(i)		the written election of the General Partner, in its sole discretion, to dissolve the Partnership;
	(ii)		the occurrence of any event that results in the General Partner ceasing to be the general partner of the Partnership under the Act, provided that the Partnership will not be dissolved and required to be wound up in connection with any such event if (A) at the time of the occurrence of such event there is at least one remaining general partner of the Partnership who is hereby authorized to and does carry on the business of the Partnership, or (B) within 90 days after the occurrence of such event, all of the Class A Partners agree in writing to continue the business of the Partnership and to the appointment, effective as of the date of such event, if required, of one or more additional general partners of the Partnership;
	(iii)		the Transfer of all or substantially all of the assets of the Partnership and the receipt and distribution of all the proceeds therefrom;
	(iv)		at any time that there are no limited partners of the Partnership, unless the business of the Partnership is continued in accordance with the Act; and
	(v)		the entry of a decree of judicial dissolution under Section 17-802 of the Act.

     (b) The withdrawal, death, dissolution, retirement, resignation, expulsion, liquidation or bankruptcy of a Partner, the admission to the Partnership of a new General Partner or Limited Partner, the withdrawal of a Partner from the Partnership, or the transfer by a Partner of its Partnership Interest to a third party shall not, in and of itself, cause the Partnership to dissolve.

8.2 Final Accounting

     Upon dissolution and winding up of the Partnership, an accounting will be made of the accounts of the Partnership and each Partner and of the Partnership’s assets, liabilities and operations from the date of the last previous accounting to the date of such dissolution.

8.3 Distributions Following Dissolution and Termination

     (a) Liquidating Trustee. Upon the dissolution of the Partnership, such party as is designated by the General Partner will act as liquidating trustee of the Partnership (the “Liquidating Trustee”) and proceed to wind up the business and affairs of the Partnership in accordance with the terms of this Agreement and applicable law. The Liquidating Trustee will use its reasonable best efforts to sell all Partnership assets (except cash) in the exercise of its best judgment under the circumstances then presented, that it deems in the best interest of the Partners. The Liquidating Trustee will attempt to convert all assets of the Partnership to cash so long as it can do so consistently with prudent business practice. The Partners and their respective designees will have the right to purchase any Partnership property to be sold on liquidation, provided that the terms on which such sale is made are no less favorable than would otherwise be available from third parties. The gains and losses from the sale of the Partnership assets, together with all other revenue, income, gain, deduction, expense, loss and credit during

the period, will be allocated in accordance with Article V. A reasonable amount of time shall be allowed for the period of winding up in light of prevailing market conditions and so as to avoid undue loss in connection with any sale of Partnership assets. This Agreement shall remain in full force and effect during the period of winding up. In addition, upon request of the General Partner and if the Liquidating Trustee determines that it would be imprudent to dispose of any non-cash assets of the Partnership, such assets may be distributed in kind to the Partners in lieu of cash, proportionately to their right to receive cash distributions hereunder.

     (b) Accounting. The Liquidating Trustee will then cause proper accounting to be made of the Capital Account of each Partner, including recognition of any unrealized gain or loss on any asset to be distributed in kind as if such asset had been sold for consideration equal to the fair market value of the asset at the time of the distribution.

     (c) Liquidating Distributions. In settling accounts after dissolution of the Partnership, the assets of the Partnership shall be paid to creditors of the Partnership and distributed to the Partners in the following order:

	(i)		to creditors of the Partnership (including Partners) in the order of priority as provided by law whether by payment or the making of reasonable provision for payment thereof, and in connection therewith there shall be withheld such reasonable reserves for contingent, conditioned or unconditioned liabilities as the Liquidating Trustee in its reasonable discretion deems adequate, such reserves (or balances thereof) to be held and distributed in such manner and at such times as the Liquidating Trustee, in its discretion, deems reasonably advisable; provided, however, that such amounts be maintained in a separate bank account and that any amounts in such bank account remaining after three years be distributed to the Partners or their successors and assigns as if such amount had been available for distribution under Section 8.3(c)(ii); and then
	(ii)		(A) First, an amount equal to Initial Grant Date Partnership Capital, 1% to the General Partner and 99% to the Class A Partners pro rata based on the number of Class A Units held; and

(B)

Second, with respect to each Subsequent Grant Date (determined in order of Subsequent Grant Date), an amount equal to the difference, if any, between the Subsequent Grant Date Partnership Capital for such Subsequent Grant Date and the Subsequent Grant Date Capital for the immediately preceding Subsequent Grant Date or, if there is no previous Subsequent Grant Date, the Initial Grant Date Partnership Capital, 1% to the General Partner and 99% to the Class A Partners and the Class B Partners, pro rata, based on the number of Class A Units held and the number of Earned Units and/or Vested Units held (to the extent of Class B Units held prior to the Subsequent Grant Date for which such determination is being made); and

(C)

Third, any remaining amounts, 1% to the General Partner and 99% to the Class A Partners and the Class B Partners, pro rata, based on the number of Class A Units, Earned Units and/or Vested Units held.

(iii)

Any distribution to the Partners in liquidation of the Partnership shall be made by the later of the end of the taxable year in which the liquidation occurs or 90 days after the date of such liquidation. For purposes of the preceding sentence, the term “liquidation” shall have the same meaning as set forth in Regulation Section 1.704-2(b)(2)(ii) as in effect at such time and liquidating distributions shall be further deemed to be made pursuant to this Agreement upon the event of a liquidation as defined in such Regulation for which no actual liquidation occurs with a deemed recontribution by the Partners of such deemed liquidating distributions to the continuing Partnership pursuant to this Agreement.

     (d) Profits and Losses arising from the dissolution and termination of the Partnership shall be allocated among the Partners so that after such allocations and the other allocations under this Agreement, to the maximum extent possible, the final Capital Account balances of the Member are at levels which would permit liquidating distributions, if made in accordance with such final Capital Account balances, to be equal to the distributions to be made under Section 8.3(c)(ii).

     (e) No Third Party Benefit. The provisions of this Agreement, including, without limitation, this Section 8.3, are intended solely to benefit the Partners and, to the fullest extent permitted by law, shall not be construed as conferring any benefit upon any creditor of the Partnership, and no such creditor of the Partnership shall be a third-party beneficiary of this Agreement, and no Partner shall have any duty or obligation to any creditor of the Partnership to issue any call for capital pursuant to this Agreement.

8.4 Termination of the Partnership

     The Partnership shall terminate when all assets of the Partnership, after payment or due provision for all debts, liabilities and obligations of the Partnership, shall have been distributed to the Partners in the manner provided for in this Article VIII, and the Certificate shall have been canceled in the manner required by the Act.

8.5 No Action for Dissolution

     The Limited Partners acknowledge that irreparable damage would be done to the goodwill and reputation of the Partnership if any Limited Partner should bring an action in court to dissolve the Partnership under circumstances where dissolution is not required by Section 8.1. Accordingly, except where the General Partner has failed to cause the liquidation of the Partnership as required by Section 8.1 and except as specifically provided in Section 17-802, each Limited Partner hereby to the fullest extent permitted by law waives and renounces his right to initiate legal action to seek dissolution of the Partnership or to seek the appointment of a receiver or trustee to wind up the affairs of the Partnership, except in the cases of fraud, violation of law, bad faith, gross negligence, willful misconduct or willful violation of this Agreement.

9.4 Financial Statements

     The General Partner shall cause to be prepared for the Partners at least annually, at the Partnership’s expense, financial statements of the Partnership, and its subsidiaries, prepared in accordance with generally accepted accounting principles and audited by a nationally recognized accounting firm. The financial statements so furnished shall include a balance sheet, statement of income or loss, statement of cash flows, and statement of Partners’ equity. In addition, the General Partner shall provide on a timely basis to the Partners monthly and quarterly financials, statements of cash flow, any available internal budgets or forecast or other available financial reports, as well as any reports or notices as are provided by the Partnership, or any of its

Subsidiaries to any financial institution. The requirements of Section 9.2(d) and this Section 9.4 shall be deemed satisfied so long as (i) the Master Limited Partnership files annual reports on Form 10-K and quarterly reports on Form 10-Q, (ii) the Master Limited Partnership files or furnishes “guidance” 8-K’s on a quarterly basis and (iii) the Master Limited Partnership annually files an 8-K attaching a balance sheet of the Partnership.

The General Partner, at the Partnership’s expense, shall also cause to be prepared and timely filed, with appropriate Federal, state and local regulatory and administrative bodies, all reports required to be filed by the Partnership with those entities under then current applicable laws, rules, and regulations.
