“ Acquisition ” means any transaction in which any Group Member acquires (through an asset acquisition, merger, stock acquisition or other form of investment) control over all or a portion of the assets, properties or business of another Person for the purpose of increasing for a period exceeding the short-term the operating capacity or operating income of the Partnership Group from the operating capacity or operating income of the Partnership Group existing immediately prior to such transaction. For purposes of this definition, the short-term generally refers to a period not exceeding 12 months.

“ Additional Book Basis ” means, with respect to any Adjusted Property, the portion of the Carrying Value of such Adjusted Property that is attributable to positive adjustments made to such Carrying Value, as determined in accordance with the provisions set forth below in this definition of Additional Book Basis. For purposes of determining the extent to which Carrying Value constitutes Additional Book Basis:

(a) Any negative adjustment made to the Carrying Value of an Adjusted Property as a result of either a Book-Down Event or a Book-Up Event shall first be deemed to offset or decrease that portion of the Carrying Value of such Adjusted Property that is attributable to any prior positive adjustments made thereto pursuant to a Book-Up Event or Book-Down Event.

(b) If Carrying Value that constitutes Additional Book Basis is reduced as a result of a Book-Down Event (an “ Additional Book Basis Reduction ”) and the Carrying Value of other property is increased as a result of such Book-Down Event (a “ Carrying Value Increase ”), then any such Carrying Value Increase shall be treated as Additional Book Basis in an amount equal to the lesser of (i) the amount of such Carrying Value Increase and (ii) the amount determined by proportionately allocating to the Carrying Value Increases resulting from such Book-Down Event by the lesser of (A) the aggregate Additional Book Basis Reductions resulting from such Book-Down Event and (B) the amount by which the Aggregate Remaining Net Positive Adjustments after such Book-Down Event exceeds the remaining Additional Book Basis attributable to all of the Partnership’s Adjusted Property after such Book-Down Event (determined without regard to the application of this clause (b) to such Book-Down Event).

“ Additional Book Basis Derivative Items ” means any Book Basis Derivative Items that are computed with reference to Additional Book Basis. To the extent that the Additional Book Basis attributable to all of the Partnership’s Adjusted Property as of the beginning of any taxable period exceeds the Aggregate Remaining Net Positive Adjustments as of the beginning of such period (the “ Excess Additional Book Basis ”), the Additional Book Basis Derivative Items for such period shall be reduced by the amount that bears the same ratio to the amount of Additional Book Basis Derivative Items determined without regard to this sentence as the Excess Additional Book Basis bears to the Additional Book Basis as of the beginning of such period. With respect to a Disposed of Adjusted Property, the Additional Book Basis Derivative Items shall be the amount of Additional Book Basis taken into account in computing gain or loss from the disposition of such Disposed of Adjusted Property; provided that the provisions of the immediately preceding sentence shall apply to the determination of the Additional Book Basis Derivative Items attributable to Disposed of Adjusted Property.

Upon surrender of a Certificate for registration of transfer of any Limited Partner Interests evidenced by a Certificate, and subject to the provisions of Section 4.5(b), the appropriate officers of the General Partner on behalf of the Partnership shall execute and deliver, and in the case of Common Units and the Series A Preferred Units, the Transfer Agent shall countersign and deliver, in the name of the holder or the designated transferee or transferees, as required pursuant to the holder’s instructions, one or more new Certificates, or shall deliver other evidence of the issuance of uncertificated Units, evidencing the same aggregate number and type of Limited Partner Interests as was evidenced by the Certificate so surrendered.

(b)    Except as otherwise provided in Section 4.9 and Section 4.11, (i) the General Partner shall not recognize any transfer of Limited Partner Interests until the Certificates evidencing such Limited Partner Interests, or other evidence of the issuance of uncertificated Units, are surrendered for registration of transfer and (ii) following a FERC Notice, such Certificates are accompanied by a Taxation Certification, properly completed and duly executed by the transferee (or the transferee’s attorney-in-fact duly authorized in writing). No charge shall be imposed by the General Partner for such transfer; provided that as a condition to the issuance of any new Certificate, or other evidence of the issuance of uncertificated Units, under this Section 4.5, the General Partner may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed with respect thereto.

(c)    Subject to (i) the foregoing provisions of this Section 4.5, (ii) Section 4.3, (iii) Section 4.8, (iv) with respect to any class or series of Limited Partner Interests, the provisions of any statement of designations or an amendment to this Agreement establishing such class or series, (v) any contractual provisions binding on any Limited Partner and (vi) provisions of applicable law including the Securities Act, Limited Partner Interests (other than the Incentive Distribution Rights) shall be freely transferable.

Section 4.6     Transfer of the General Partner’s General Partner Interest .

(a)    Subject to Section 4.6(c) below, prior to June 30, 2018, the General Partner shall not transfer all or any part of its General Partner Interest (represented by General Partner Units) to a

Person unless such transfer (i) has been approved by the prior written consent or vote of the holders of at least a majority of the Outstanding Common Units (excluding Common Units held by the General Partner and its Affiliates) or (ii) is of all, but not less than all, of its General Partner Interest to (A) an Affiliate of the General Partner (other than an individual) or (B) another Person (other than an individual) in connection with the merger or consolidation of the General Partner with or into such other Person or the transfer by the General Partner of all or substantially all of its assets to such other Person.

(b)    Subject to Section 4.6(c) below, on or after June 30, 2018, the General Partner may transfer all or any of its General Partner Interest without Unitholder approval.

(c)    Notwithstanding anything herein to the contrary, no transfer by the General Partner of all or any part of its General Partner Interest to another Person shall be permitted unless (i) the transferee agrees to assume the rights and duties of the General Partner under this Agreement and to be bound by the provisions of this Agreement, (ii) the Partnership receives an Opinion of Counsel that such transfer would not result in the loss of limited liability of any Limited Partner under the Delaware Act or cause the Partnership to be treated as an association taxable as a corporation or otherwise to be taxed as an entity for federal income tax purposes (to the extent not already so treated or taxed) and (iii) such transferee also agrees to purchase all (or the appropriate portion thereof, if applicable) of the partnership or membership or limited liability company interest of the General Partner as the general partner or managing member, if any, of each other Group Member. In the case of a transfer pursuant to and in compliance with this Section 4.6, the transferee or successor (as the case may be) shall, subject to compliance with the terms of Section 10.2, be admitted to the Partnership as the General Partner effective immediately prior to the transfer of the General Partner Interest, and the business of the Partnership shall continue without dissolution.

Any other transfer of the Incentive Distribution Rights prior to June 30, 2018 shall require the prior approval of holders of at least a majority of the Outstanding Common Units (excluding Common Units held by the General Partner and its Affiliates). On or after June 30, 2018, the General Partner or any other holder of Incentive Distribution Rights may transfer any or all of its Incentive Distribution Rights without Unitholder approval. Notwithstanding anything herein to the contrary, (i) the transfer of Class B Units issued pursuant to Section 5.11, or the transfer of Common Units issued upon conversion of the Class B Units, shall not be treated as a transfer of all or any part of the Incentive Distribution Rights and (ii) no transfer of Incentive Distribution Rights to another Person shall be permitted unless the transferee agrees to be bound by the provisions of this Agreement.

Section 4.8     Restrictions on Transfers .

(a)    Notwithstanding the other provisions of this Article IV, no transfer of any Partnership Interests shall be made if such transfer would (i) violate the then applicable federal or state securities laws or rules and regulations of the Commission, any state securities commission or any other governmental authority with jurisdiction over such transfer, (ii) terminate the existence or qualification of the Partnership under the laws of the jurisdiction of its formation, or (iii) cause the Partnership to be treated as an association taxable as a corporation or otherwise to be taxed as an entity for federal income tax purposes (to the extent not already so treated or taxed).

(b)    The General Partner may impose restrictions on the transfer of Partnership Interests if it receives an Opinion of Counsel that such restrictions are necessary to avoid a significant risk of the Partnership becoming taxable as a corporation or otherwise becoming taxable as an entity for federal income tax purposes. The General Partner may impose such restrictions by amending this Agreement; provided, however , that any amendment that would result in the delisting or suspension of trading of any class of Limited Partner Interests on the principal National Securities Exchange on which such class of Limited Partner Interests is then listed or admitted to trading must be approved, prior to such amendment being effected, by the holders of at least a majority of the Outstanding Limited Partner Interests of such class.

THE HOLDER OF THIS SECURITY ACKNOWLEDGES FOR THE BENEFIT OF WESTERN GAS PARTNERS, LP THAT THIS SECURITY MAY NOT BE SOLD, OFFERED, RESOLD, PLEDGED OR OTHERWISE TRANSFERRED IF SUCH TRANSFER WOULD (A) VIOLATE THE THEN APPLICABLE FEDERAL OR STATE SECURITIES LAWS OR RULES AND REGULATIONS OF THE SECURITIES AND EXCHANGE COMMISSION, ANY STATE SECURITIES COMMISSION OR ANY OTHER GOVERNMENTAL AUTHORITY WITH JURISDICTION OVER SUCH

TRANSFER, (B) TERMINATE THE EXISTENCE OR QUALIFICATION OF WESTERN GAS PARTNERS, LP UNDER THE LAWS OF THE STATE OF DELAWARE, OR (C) CAUSE WESTERN GAS PARTNERS, LP TO BE TREATED AS AN ASSOCIATION TAXABLE AS A CORPORATION OR OTHERWISE TO BE TAXED AS AN ENTITY FOR FEDERAL INCOME TAX PURPOSES (TO THE EXTENT NOT ALREADY SO TREATED OR TAXED). WESTERN GAS HOLDINGS, LLC, THE GENERAL PARTNER OF WESTERN GAS PARTNERS, LP, MAY IMPOSE ADDITIONAL RESTRICTIONS ON THE TRANSFER OF THIS SECURITY IF IT RECEIVES AN OPINION OF COUNSEL THAT SUCH RESTRICTIONS ARE NECESSARY TO AVOID A SIGNIFICANT RISK OF WESTERN GAS PARTNERS, LP BECOMING TAXABLE AS A CORPORATION OR OTHERWISE BECOMING TAXABLE AS AN ENTITY FOR FEDERAL INCOME TAX PURPOSES. THE RESTRICTIONS SET FORTH ABOVE SHALL NOT PRECLUDE THE SETTLEMENT OF ANY TRANSACTIONS INVOLVING THIS SECURITY ENTERED INTO THROUGH THE FACILITIES OF ANY NATIONAL SECURITIES EXCHANGE ON WHICH THIS SECURITY IS LISTED OR ADMITTED TO TRADING.

Section 4.9     Citizenship Certificates; Non-citizen Assignees .

(a)    If any Group Member is or becomes subject to any federal, state or local law or regulation that the General Partner determines would create a substantial risk of cancellation or forfeiture of any property in which the Group Member has an interest based on the nationality, citizenship or other related status of a Limited Partner, the General Partner may request any Limited Partner to furnish to the General Partner, within 30 days after receipt of such request, an executed Citizenship Certification or such other information concerning his nationality, citizenship or other related status (or, if the Limited Partner is a nominee holding for the account of another Person, the nationality, citizenship or other related status of such Person) as the General Partner may request. If a Limited Partner fails to furnish to the General Partner within the aforementioned 30-day period such Citizenship Certification or other requested information or if upon receipt of such Citizenship Certification or other requested information the General Partner determines that a Limited Partner is not an Eligible Citizen, the Limited Partner Interests owned by such Limited Partner shall be subject to redemption in accordance with the provisions of Section 4.10. In addition, the General Partner may require that the status of any such Limited Partner be changed to that of a Non-citizen Assignee and, thereupon, the General Partner shall be substituted for such Non-citizen Assignee as the Limited Partner in respect of the Non-citizen Assignee’s Limited Partner Interests.

(b)    The General Partner shall, in exercising voting rights in respect of Limited Partner Interests held by it on behalf of Non-citizen Assignees, distribute the votes in the same ratios as the votes of Partners (including the General Partner) in respect of Limited Partner Interests other than those of Non-citizen Assignees are cast, either for, against or abstaining as to the matter.

(c)    Upon dissolution of the Partnership, a Non-citizen Assignee shall have no right to receive a distribution in kind pursuant to Section 12.4 but shall be entitled to the cash equivalent thereof, and the Partnership shall provide cash in exchange for an assignment of the Non-citizen Assignee’s share of any distribution in kind. Such payment and assignment shall be treated for

Partnership purposes as a purchase by the Partnership from the Non-citizen Assignee of his Limited Partner Interest (representing his right to receive his share of such distribution in kind).

(d)    At any time after he can and does certify that he has become an Eligible Citizen, a Non-citizen Assignee may, upon application to the General Partner, request that with respect to any Limited Partner Interests of such Non-citizen Assignee not redeemed pursuant to Section 4.10, such Non-citizen Assignee be admitted as a Limited Partner, and upon approval of the General Partner, such Non-citizen Assignee shall be admitted as a Limited Partner and shall no longer constitute a Non-citizen Assignee and the General Partner shall cease to be deemed to be the Limited Partner in respect of the Non-citizen Assignee’s Limited Partner Interests.

Section 4.10     Redemption of Partnership Interests of Non-citizen Assignees .

(a)    If at any time a Limited Partner fails to furnish a Citizenship Certification or other information requested within the 30-day period specified in Section 4.9(a), or if upon receipt of such Citizenship Certification or other information the General Partner determines, with the advice of counsel, that a Limited Partner is not an Eligible Citizen, the Partnership may, unless the Limited Partner establishes to the satisfaction of the General Partner that such Limited Partner is an Eligible Citizen or has transferred his Partnership Interests to a Person who is an Eligible Citizen and who furnishes a Citizenship Certification to the General Partner prior to the date fixed for redemption as provided below, redeem the Limited Partner Interest of such Limited Partner as follows:

(i)    The General Partner shall, not later than the 30th day before the date fixed for redemption, give notice of redemption to the Limited Partner, at his last address designated on the records of the Partnership or the Transfer Agent, by registered or certified mail, postage prepaid. The notice shall be deemed to have been given when so mailed. The notice shall specify the Redeemable Interests, the date fixed for redemption, the place of payment, that payment of the redemption price will be made upon surrender of the Certificate evidencing the Redeemable Interests, or other evidence of the issuance of uncertificated Units, and that on and after the date fixed for redemption no further allocations or distributions to which the Limited Partner would otherwise be entitled in respect of the Redeemable Interests will accrue or be made.

(ii)    The aggregate redemption price for Redeemable Interests shall be an amount equal to the Current Market Price (the date of determination of which shall be the date fixed for redemption) of Limited Partner Interests of the class to be so redeemed multiplied by the number of Limited Partner Interests of each such class included among the Redeemable Interests. The redemption price shall be paid, as determined by the General Partner, in cash or by delivery of a promissory note of the Partnership in the principal amount of the redemption price, bearing interest at the rate of 5% annually and payable in three equal annual installments of principal together with accrued interest, commencing one year after the redemption date.

(iii)    Upon surrender by or on behalf of the Limited Partner, at the place specified in the notice of redemption, of the Certificate evidencing the Redeemable Interests, duly endorsed in blank or accompanied by an assignment duly executed in blank, or other evidence

of the issuance of uncertificated Units, the Limited Partner or his duly authorized representative shall be entitled to receive the payment therefor.

(iv)    After the redemption date, Redeemable Interests shall no longer constitute issued and Outstanding Limited Partner Interests.

(b)    The provisions of this Section 4.10 shall also be applicable to Limited Partner Interests held by a Limited Partner as nominee of a Person determined to be other than an Eligible Citizen.

(c)    Nothing in this Section 4.10 shall prevent the recipient of a notice of redemption from transferring his Limited Partner Interest before the redemption date if such transfer is otherwise permitted under this Agreement. Upon receipt of notice of such a transfer, the General Partner shall withdraw the notice of redemption, provided the transferee of such Limited Partner Interest certifies to the satisfaction of the General Partner that he is an Eligible Citizen. If the transferee fails to make such certification, such redemption shall be effected from the transferee on the original redemption date.

Section 4.11     Taxation Certifications; Ineligible Assignees.

(a)    Following a FERC Notice, if a transferee of a Limited Partner Interest fails to furnish a properly completed Taxation Certification in the manner specified in Section 4.5(b) or if, upon receipt of such Taxation Certification or otherwise, the General Partner determines that such transferee is not an Eligible Holder, the Limited Partner Interests owned by such transferee shall be subject to redemption in accordance with the provisions of Section 4.12.

(b)    The General Partner may request any Limited Partner to furnish to the General Partner, within 30 days after receipt of such request, an executed Taxation Certification or such other information concerning his federal income tax status with respect to the income and loss generated by the Partnership (or, if the Limited Partner is a nominee holding for the account of another Person, the federal income tax status of such Person) as the General Partner may reasonably request. If a Limited Partner or Assignee fails to furnish to the General Partner within the aforementioned 30-day period such Taxation Certification or other requested information or if upon receipt of such Taxation Certification or other requested information the General Partner determines that a Limited Partner is an Ineligible Assignee, the Limited Partner Interests owned by such Limited Partner shall be subject to redemption in accordance with the provisions of Section 4.12. The General Partner shall be substituted for such Ineligible Assignee as the Limited Partner in respect of the Ineligible Assignee's Limited Partner Interests. Upon determination by the General Partner that such person is an Ineligible Assignee, the General Partner may elect to not make distributions or allocations of income or loss to such Ineligible Assignee relating to such Ineligible Assignee’s Limited Partner Interests.

(c)    Following a FERC Notice or any other determination of an Ineligible Assignee, the General Partner shall, in exercising voting rights in respect of Limited Partner Interests held by it on behalf of Ineligible Assignees, distribute the votes in the same ratios as the votes of Partners

(including without limitation the General Partner) in respect of Limited Partner Interests other than those of Ineligible Assignees are cast, either for, against or abstaining as to the matter.

(d)    Upon dissolution of the Partnership, an Ineligible Assignee shall have no right to receive a distribution in kind pursuant to Section 12.4 but shall be entitled to the cash equivalent thereof, and the Partnership shall provide cash in exchange for an assignment of the Ineligible Assignee's share of any distribution in kind. Such payment and assignment shall be treated for Partnership purposes as a purchase by the Partnership from the Ineligible Assignee of his Limited Partner Interest (representing his right to receive his share of such distribution in kind).

(e)    At any time after an Ineligible Assignee can and does certify that it has become an Eligible Holder, such Ineligible Assignee may, upon application to the General Partner, request that with respect to any Limited Partner Interests of such Ineligible Assignee not redeemed pursuant to Section 4.12, such Ineligible Assignee be admitted as a Limited Partner, and upon approval of the General Partner, such Ineligible Assignee shall be admitted as a Limited Partner and shall no longer constitute an Ineligible Assignee and the General Partner shall cease to be deemed to be the Limited Partner in respect of such Ineligible Assignee's Limited Partner Interests.

Section 4.12     Redemption of Partnership Interests of Ineligible Assignees.

(a)    If at any time following a FERC Notice or a request pursuant to Section 4.11(b), a transferee of a Limited Partner Interest fails to furnish the General Partner a Taxation Certification in the manner specified in Section 4.5(b) or any Limited Partner fails to furnish the General Partner a Taxation Certification or other information requested within the 30-day period specified in Section 4.11(b), or if upon receipt of such Taxation Certification or other information the General Partner determines that a Limited Partner or transferee is not an Eligible Holder, the Partnership may redeem the Limited Partner Interest of such Limited Partner or transferee as follows:

(i)    The General Partner shall, not later than the 30th day before the date fixed for redemption, give notice of redemption to the Limited Partner or transferee, at his last address designated on the records of the Partnership or the Transfer Agent, by registered or certified mail, postage prepaid. The notice shall be deemed to have been given when so mailed. The notice shall specify the Redeemable Interests, the date fixed for redemption, the place of payment, that payment of the redemption price will be made upon surrender of the Certificate evidencing the Redeemable Interests or, if uncertificated, upon receipt of evidence satisfactory to the General Partner of the ownership of the Redeemable Interests, and that on and after the date fixed for redemption no further allocations or distributions to which the Limited Partner would otherwise be entitled in respect of the Redeemable Interests will accrue or be made.

(ii)    The aggregate redemption price for Redeemable Interests shall be an amount equal to the lesser of (A) the Current Market Price (the date of determination of which shall be the date fixed for redemption) of Limited Partner Interests of the class to be so redeemed multiplied by the number of Limited Partner Interests of each such class included among the Redeemable Interests and (B) the price paid for such Limited Partner Interests by the Limited Partner or transferee. The redemption price shall be paid as determined by the

General Partner, in cash or by delivery of a promissory note of the Partnership in the principal amount of the redemption price, bearing interest at the rate of 5% annually and payable in three equal annual installments of principal together with accrued interest, commencing one year after the redemption date.

(iii)    Upon surrender by or on behalf of the Limited Partner, at the place specified in the notice of redemption, of (x) if certificated, the Certificate evidencing the Redeemable Interests, duly endorsed in blank or accompanied by an assignment duly executed in blank, or (y) if uncertificated, upon receipt of evidence satisfactory to the General Partner of the ownership of the Redeemable Interests, the Limited Partner or transferee or his duly authorized representative shall be entitled to receive the payment therefor.

(iv)    After the redemption date, Redeemable Interests shall no longer constitute issued and Outstanding Limited Partner Interests.

(b)    The provisions of this Section 4.12 shall also be applicable to Limited Partner Interests held by a Limited Partner as nominee of a Person determined to be other than an Eligible Holder.

(c)    Nothing in this Section 4.12 shall prevent the recipient of a notice of redemption from transferring his Limited Partner Interest before the redemption date if such transfer is otherwise permitted under this Agreement. Upon receipt of notice of such a transfer, the General Partner shall withdraw the notice of redemption, provided the transferee of such Limited Partner Interest certifies to the satisfaction of the General Partner in a Taxation Certification that he is an Eligible Holder. If the transferee fails to make such certification, such redemption shall be effected from the transferee on the original redemption date.

In exchange for such Capital Contributions by the Underwriters, the Partnership issued Common Units to each Underwriter on whose behalf such Capital Contribution was made in an amount equal to the quotient obtained by dividing (i) the cash contribution to the Partnership by or on behalf of such Underwriter by (ii) the Issue Price per Initial Common Unit.

(b)    Upon the exercise of the Over-Allotment Option, each Underwriter contributed to the Partnership cash in an amount equal to the Issue Price per Initial Common Unit, multiplied by the number of Common Units to be purchased by such Underwriter at such Option Closing Date.

Section 5.4     Interest and Withdrawal .

No interest shall be paid by the Partnership on Capital Contributions. No Partner shall be entitled to the withdrawal or return of its Capital Contribution, except to the extent, if any, that distributions made pursuant to this Agreement or upon liquidation of the Partnership may be considered as such by law and then only to the extent provided for in this Agreement. Except to the extent expressly provided in this Agreement, no Partner shall have priority over any other Partner either as to the return of Capital Contributions or as to profits, losses or distributions. Any such return shall be a compromise to which all Partners agree within the meaning of Section 17-502(b) of the Delaware Act.

Section 5.5     Capital Accounts .

(a)    The Partnership shall maintain for each Partner (or a beneficial owner of Partnership Interests held by a nominee, agent or representative in any case in which the nominee, agent or representative has furnished the identity of such owner to the Partnership in accordance with Section 6031(c) of the Code or any other method acceptable to the General Partner) owning a Partnership Interest a separate Capital Account with respect to such Partnership Interest in accordance with the rules of Treasury Regulation Section 1.704-1(b)(2)(iv). Such Capital Account shall be increased by (i) the amount of all Capital Contributions made by the Partner with respect to such Partnership Interest and (ii) all items of Partnership income and gain computed in accordance with Section 5.5(b) and allocated with respect to such Partnership Interest pursuant to Section 6.1, and decreased by (x) the amount of cash or Net Agreed Value of all actual and deemed distributions of cash or property (provided that PIK C Units shall not be deemed property for these purposes) made to the Partner with respect to such Partnership Interest, provided that the Capital Account of a Partner shall not be reduced by the amount of any distributions made with respect to Restricted Common Units held by such Partner, and (y) all items of Partnership deduction and loss computed in accordance with Section 5.5(b) and allocated with respect to such Partnership Interest pursuant to Section 6.1. The initial Capital Account balance in respect of each Class C Unit (other than PIK C Units) shall be equal to the Purchase Price set forth in Section 1(a) of the Unit Purchase Agreement. The initial Capital Account balance in respect of each PIK C Unit shall be determined in accordance with Section 5.12(d)(iv). For the avoidance of doubt, the Series A Preferred Units will be treated

as a partnership interest in the Partnership that is “convertible equity” within the meaning of Treasury Regulation Section 1.721-2(g)(3), and, therefore, each holder of a Series A Preferred Unit will be treated as a partner in the Partnership. The initial Capital Account balance in respect of each Series A Preferred Unit shall be the Series A Issue Price, as such amount may be adjusted in accordance with the Series A Purchase Agreement for any reduction attributable to the Transaction Fee, as such term is defined in the Series A Purchase Agreement and expenses reimbursable under the Series A Purchase Agreement.

(b)    For purposes of computing the amount of any item of income, gain, loss or deduction which is to be allocated pursuant to Article VI and is to be reflected in the Partners’ Capital Accounts, the determination, recognition and classification of any such item shall be the same as its determination, recognition and classification for federal income tax purposes (including any method of depreciation, cost recovery or amortization used for that purpose), provided that:

(i)    Solely for purposes of this Section 5.5, the Partnership shall be treated as owning directly its proportionate share (as determined by the General Partner based upon the provisions of the applicable Group Member Agreement or governing, organizational or similar documents) of all property owned by (x) any other Group Member that is classified as a partnership for federal income tax purposes and (y) any other partnership, limited liability company, unincorporated business or other entity classified as a partnership for federal income tax purposes of which a Group Member is, directly or indirectly, a partner.

(ii)    All fees and other expenses incurred by the Partnership to promote the sale of (or to sell) a Partnership Interest that can neither be deducted nor amortized under Section 709 of the Code, if any, shall, for purposes of Capital Account maintenance, be treated as an item of deduction at the time such fees and other expenses are incurred and shall be allocated among the Partners pursuant to Section 6.1.

(iii)    The computation of all items of income, gain, loss and deduction shall be made (x) except as otherwise provided in this Agreement and Treasury Regulation Section 1.704-1(b)(2)(iv)(m), without regard to any election under Section 754 of the Code that may be made by the Partnership, and (y) as to those items described in Section 705(a)(1)(B) or 705(a)(2)(B) of the Code, without regard to the fact that such items are not includable in gross income or are neither currently deductible nor capitalized for U.S. federal income tax purposes.

(iv)    To the extent an adjustment to the adjusted tax basis of any Partnership asset pursuant to Section 734(b) of the Code (including pursuant to Treasury Regulation Section 1.734-2(b)(1)) is required, pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts, the amount of such adjustment in the Capital Accounts shall be treated as an item of gain or loss.

(v)    In the event the Carrying Value of Partnership property is adjusted pursuant to Section 5.5(d), any Unrealized Gain resulting from such adjustment shall be treated as an item of gain and any Unrealized Loss resulting from such adjustment shall be treated as an item of loss.

(vi)    Any income, gain or loss attributable to the taxable disposition of any Partnership property shall be determined as if the adjusted basis of such property as of such date of disposition were equal in amount to the property’s Carrying Value as of such date.

(vii)    Any deductions for depreciation, cost recovery or amortization attributable to any Contributed Property or Adjusted Property shall be determined under the rules prescribed by Treasury Regulation Section 1.704-3(d) as if the adjusted basis of such property were equal to the Carrying Value of such property.

(viii)    The Gross Liability Value of each Liability of the Partnership described in Treasury Regulation Section 1.752-7(b)(3)(i) shall be adjusted at such times as provided in this Agreement for an adjustment to the Carrying Values of Partnership property. The amount of any such adjustment shall be treated for purposes hereof as an item of loss (if the adjustment increases the Carrying Value of such Liability of the Partnership) or an item of gain (if the adjustment decreases the Carrying Value of such Liability of the Partnership).

(c)    (i)    A transferee of a Partnership Interest shall succeed to a pro rata portion of the Capital Account of the transferor relating to the Partnership Interest so transferred.

(ii)    Subject to Section 6.7(d), immediately prior to the transfer of a Class C Unit or of a Class C Unit that has converted into a Common Unit pursuant to Section 5.12 by a holder thereof (other than a transfer to an Affiliate unless the General Partner elects to have this subparagraph 5.5(c)(iii) apply), the Capital Account maintained for such Person with respect to its Class C Units or Converted Class C Units will (A) first, be allocated to the Class C Units or Converted Class C Units to be transferred in an amount equal to the product of (x) the number of such Class C Units or Converted Class C Units to be transferred and (y) the Per Unit Capital Amount for a Common Unit, and (B) second, any remaining balance in such Capital Account will be retained by the transferor, regardless of whether it has retained any Class C Units or Converted Class C Units (“ Retained Converted Class C Units ”). Following any such allocation, the transferor’s Capital Account, if any, maintained with respect to the retained Class C Units or Retained Converted Class C Units, if any, will have a balance equal to the amount allocated under clause (B) hereinabove, and the transferee’s Capital Account established with respect to the transferred Class C Units or Converted Class C Units will have a balance equal to the amount allocated under clause (A) hereinabove.

(d)    (i)    Consistent with Treasury Regulation Sections 1.704-1(b)(2)(iv)(f) and 1.704-1(b)(2)(iv)(h)(2), on an issuance of additional Partnership Interests for cash or Contributed Property (including the issuance of a PIK C Unit), the issuance of a Noncompensatory Option, the issuance of Partnership Interests as consideration for the provision of services (including upon the lapse of a “substantial risk of forfeiture” with respect to a Restricted Common Unit), the issuance of Class B Units pursuant to Section 5.11, the conversion of the Combined Interest to Common Units pursuant to Section 11.3(b), the conversion of Series A Preferred Units to Common Units pursuant to Section 5.13(b)(vi), or the conversion of Class C Units to Common Units pursuant to Section 5.12(c), the Capital Accounts of all Partners and the Carrying Value of each Partnership property immediately prior to such issuance or after such conversion shall be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Partnership

property; provided, however , that in the event of the issuance of a Partnership Interest pursuant to the exercise of a Noncompensatory Option (which, for purposes hereof, shall include any conversion of Series A Preferred Units to Common Units pursuant to Section 5.13(b)(vi)) where the right to share in Partnership capital represented by such Partnership Interest differs from the consideration paid to acquire and exercise such option, the Carrying Value of each Partnership property immediately after the issuance of such Partnership Interest shall be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Partnership property and the Capital Accounts of the Partners shall be adjusted in a manner consistent with Treasury Regulation Section 1.704-1(b)(2)(iv)(s); provided, further , that in the event of an issuance of Partnership Interests for a de minimis amount of cash or Contributed Property, in the event of an issuance of a Noncompensatory Option to acquire a de minimis Partnership Interest or in the event of an issuance of a de minimis amount of Partnership Interests as consideration for the provision of services, the General Partner may determine that such adjustments are unnecessary for the proper administration of the Partnership. In determining such Unrealized Gain or Unrealized Loss, the aggregate fair market value of all Partnership property (including cash or cash equivalents) immediately prior to the issuance of additional Partnership Interests (or, in the case of a Revaluation Event resulting from the exercise of a Noncompensatory Option (which, for purposes hereof, shall include any conversion of Series A Preferred Units to Common Units pursuant to Section 5.13(b)(vi)), immediately after the issuance of the Partnership Interest acquired pursuant to the exercise of such Noncompensatory Option) shall be determined by the General Partner using such method of valuation as it may adopt. In making its determination of the fair market values of individual properties, the General Partner may first determine an aggregate value for the assets of the Partnership that takes into account the current trading price of the Common Units, the fair market value of all other Partnership Interests at such time, and the value of Partnership Liabilities. The General Partner may allocate such aggregate value among the individual properties of the Partnership (in such manner as it determines appropriate). Absent a contrary determination by the General Partner, the aggregate fair market value of all Partnership assets (including, without limitation, cash or cash equivalents) immediately prior to a Revaluation Event shall be the value that would result in the Capital Account for each Common Unit that is Outstanding prior to such Revaluation Event being equal to the Event Issue Value.

(ii)    In accordance with Treasury Regulation Sections 1.704-1(b)(2)(iv)(f) and 1.704-1(b)(2)(iv)(h)(2), immediately prior to any distribution to a Partner of any Partnership property (other than a distribution of cash that is not in redemption or retirement of a Partnership Interest), the Carrying Value of all Partnership property shall be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Partnership property. In determining such Unrealized Gain or Unrealized Loss the aggregate fair market value of all Partnership property (including cash or cash equivalents) immediately prior to a distribution shall (A) in the case of a distribution other than one made pursuant to Section 12.4, be determined in the same manner as that provided in Section 5.5(d)(i) or (B) in the case of a liquidating distribution pursuant to Section 12.4, be determined by the Liquidator using such method of valuation as it may adopt.

Section 5.6     Issuances of Additional Partnership Securities .

(a)    Subject to Section 5.13(b)(iv), the Partnership may issue additional Partnership Securities and options, rights, warrants and appreciation rights relating to the Partnership Securities (including pursuant to Section 7.4(c)) for any Partnership purpose at any time and from time to time to such Persons for such consideration and on such terms and conditions as the General Partner shall determine, all without the approval of any Limited Partners.

(b)    Each additional Partnership Security authorized to be issued by the Partnership pursuant to Section 5.6(a) or security authorized to be issued pursuant to Section 7.4(c) may be issued in one or more classes, or one or more series of any such classes, with such designations, preferences, rights, powers and duties (which may be senior to existing classes and series of Partnership Securities), as shall be fixed by the General Partner, including (i) the right to share in Partnership profits and losses or items thereof; (ii) the right to share in Partnership distributions; (iii) the rights upon dissolution and liquidation of the Partnership; (iv) whether, and the terms and conditions upon which, the Partnership may redeem the Partnership Security or other security; (v) whether such Partnership Security or other security is issued with the privilege of conversion or exchange and, if so, the terms and conditions of such conversion or exchange; (vi) the terms and conditions upon which each Partnership Security or other security will be issued, evidenced by certificates and assigned or transferred; (vii) the method for determining the Percentage Interest as to such Partnership Security; and (viii) the right, if any, of each such Partnership Security to vote on Partnership matters, including matters relating to the relative rights, preferences and privileges of such Partnership Security.

(c)    The General Partner shall take all actions that it determines to be necessary or appropriate in connection with (i) each issuance of Partnership Securities and options, rights, warrants and appreciation rights relating to Partnership Securities pursuant to this Section 5.6, or Section 7.4(c), (ii) the conversion of the General Partner Interest (represented by General Partner Units) or any Incentive Distribution Rights into Units pursuant to the terms of this Agreement, (iii) the issuance of Class B Units pursuant to Section 5.11 and the conversion of Class B Units into Common Units pursuant to the terms of this Agreement, (iv) the issuance of Class C Units pursuant to Section 5.12 and the conversion of Class C Units into Common Units pursuant to the terms of this Agreement, (v) the issuance of Series A Preferred Units pursuant to Section 5.13 and the conversion of Series A Preferred Units into Common Units pursuant to the terms of this Agreement, (vi) reflecting admission of such additional Limited Partners in the books and records of the Partnership as the Record Holder of such Limited Partner Interest and (vii) all additional issuances of Partnership Securities. The General Partner shall determine the relative rights, powers and duties of the holders of the Units or other Partnership Securities being so issued. The General Partner shall do all things necessary to comply with the Delaware Act and is authorized and directed to do all things that it determines to be necessary or appropriate in connection with any future issuance of Partnership Securities or in connection with the conversion of the General Partner Interest or any Incentive Distribution Rights into Units pursuant to the terms of this Agreement, including compliance with any statute, rule, regulation or guideline of any federal, state or other governmental agency or any National Securities Exchange on which the Units or other Partnership Securities are listed or admitted to trading.

(d)    No fractional Units shall be issued by the Partnership.

Section 5.7     [Reserved]

Section 5.8     Limited Preemptive Right .

Except as provided in this Section 5.8 and in Section 5.2, no Person shall have any preemptive, preferential or other similar right with respect to the issuance of any Partnership Security, whether unissued, held in the treasury or hereafter created. The General Partner shall have the right, which it may from time to time assign in whole or in part to any of its Affiliates, to purchase Partnership Securities from the Partnership whenever, and on the same terms that, the Partnership issues Partnership Securities to Persons other than the General Partner and its Affiliates, to the extent necessary to maintain the Percentage Interests of the General Partner and its Affiliates equal to that which existed immediately prior to the issuance of such Partnership Securities.

Section 5.9     Splits and Combinations .

(a)    Subject to Section 5.9(d), Section 6.6 and Section 6.9 (dealing with adjustments of distribution levels), the Partnership may make a Pro Rata distribution of Partnership Securities to all Record Holders or may effect a subdivision or combination of Partnership Securities so long as, after any such event, each Partner shall have the same Percentage Interest in the Partnership as before such event, and any amounts calculated on a per Unit basis or stated as a number of Units are proportionately adjusted.

(b)    Whenever such a distribution, subdivision or combination of Partnership Securities is declared, the General Partner shall select a Record Date as of which the distribution, subdivision or combination shall be effective and shall send notice thereof at least 20 days prior to such Record Date to each Record Holder as of a date not less than 10 days prior to the date of such notice. The General Partner also may cause a firm of independent public accountants selected by it to calculate the number of Partnership Securities to be held by each Record Holder after giving effect to such distribution, subdivision or combination. The General Partner shall be entitled to rely on any certificate provided by such firm as conclusive evidence of the accuracy of such calculation.

(c)    Promptly following any such distribution, subdivision or combination, the Partnership may issue Certificates, or other evidence of the issuance of uncertificated Units, to the Record Holders of Partnership Securities as of the applicable Record Date representing the new number of Partnership Securities held by such Record Holders, or the General Partner may adopt such other procedures that it determines to be necessary or appropriate to reflect such changes. If any such combination results in a smaller total number of Partnership Securities Outstanding, the Partnership shall require, as a condition to the delivery to a Record Holder of such new Certificate, or other evidence of the issuance of uncertificated Units, the surrender of any Certificate, or other evidence of the issuance of uncertificated Units, held by such Record Holder immediately prior to such Record Date.

(d)    The Partnership shall not issue fractional Units upon any distribution, subdivision or combination of Units. If a distribution, subdivision or combination of Units would result in the

issuance of fractional Units but for the provisions of this Section 5.9(d), each fractional Unit shall be rounded to the nearest whole Unit (and a 0.5 Unit shall be rounded to the next higher Unit).

(e)    For the avoidance of doubt, upon any pro rata distribution of Common Units to all Record Holders of Common Units or any subdivision or combination (or reclassification into a greater or smaller number) of Common Units, the Partnership will proportionately adjust the number of Class C Units as follows: (i) if the Partnership issues Common Units as a distribution on its Common Units or subdivides the Common Units (or reclassifies them into a greater number of Common Units) then the Class C Units shall be subdivided into a number of Class C Units equal to the result of multiplying the number of Class C Units by a fraction, (A) the numerator of which shall be the sum of the number of Common Units outstanding immediately prior to such distribution or subdivision plus the total number of Common Units constituting such distribution or newly created by such subdivision; and (B) the denominator of which shall be the number of Common Units outstanding immediately prior to such distribution or subdivision; and (ii) if the Partnership combines the Common Units (or reclassifies them into a smaller number of Common Units) then the Class C Units shall be combined into a number of Class C Units equal to the result of multiplying the number of Class C Units by a fraction, (A) the numerator of which shall be the sum of the number of Common Units outstanding immediately following such combination; and (B) the denominator of which shall be the number of Common Units outstanding immediately prior to such combination.

Section 5.10     Fully Paid and Non-Assessable Nature of Limited Partner Interests .

All Limited Partner Interests issued pursuant to, and in accordance with the requirements of, this Article V shall be fully paid and non-assessable Limited Partner Interests in the Partnership, except as such non-assessability may be affected by Sections 17-303, 17-607 and 17-804 of the Delaware Act.

Section 5.11     Issuance of Class B Units in Connection with Reset of Incentive Distribution Rights .

(a)    Subject to the provisions of this Section 5.11, the holder of the Incentive Distribution Rights (or, if there is more than one holder of the Incentive Distribution Rights, the holders of a majority in interest of the Incentive Distribution Rights) shall have the right, at any time when the Partnership has made a distribution pursuant to Section 6.4(e) for each of the four most recently completed Quarters and the amount of each such distribution did not exceed Adjusted Operating Surplus for such Quarter, to make an election (the “ IDR Reset Election ”) to cause the Minimum Quarterly Distribution and the Target Distributions to be reset in accordance with the provisions of Section 5.11(e) and, in connection therewith, the holder or holders of the Incentive Distribution Rights will become entitled to receive their respective proportionate share of a number of Class B Units derived by dividing (i) the average amount of cash distributions made by the Partnership for the two full Quarters immediately preceding the giving of the Reset Notice (as defined in Section 5.11(b)) in respect of the Incentive Distribution Rights by (ii) the average of the cash distributions made by the Partnership in respect of each Common Unit for the two full Quarters immediately preceding the giving of the Reset Notice (the number of Class B Units determined by such quotient is referred to herein as the “ Aggregate Quantity of Class B Units ”). Upon the issuance of such Class

B Units, the Partnership will issue to the General Partner that number of additional General Partner Units equal to the product of (x) the quotient obtained by dividing (A) the Percentage Interest of the General Partner immediately prior to such issuance by (B) a percentage equal to 100% less such Percentage Interest by (y) the number of such Class B Units, and the General Partner shall not be obligated to make any additional Capital Contribution to the Partnership in exchange for such issuance. The making of the IDR Reset Election in the manner specified in Section 5.11(b) shall cause the Minimum Quarterly Distribution and the Target Distributions to be reset in accordance with the provisions of Section 5.11(e) and, in connection therewith, the holder or holders of the Incentive Distribution Rights will become entitled to receive Class B Units and General Partner Units on the basis specified above, without any further approval required by the General Partner or the Unitholders, at the time specified in Section 5.11(c) unless the IDR Reset Election is rescinded pursuant to Section 5.11(d).

(b)    To exercise the right specified in Section 5.11(a), the holder of the Incentive Distribution Rights (or, if there is more than one holder of the Incentive Distribution Rights, the holders of a majority in interest of the Incentive Distribution Rights) shall deliver a written notice (the “ Reset Notice ”) to the Partnership. Within 10 Business Days after the receipt by the Partnership of such Reset Notice, as the case may be, the Partnership shall deliver a written notice to the holder or holders of the Incentive Distribution Rights of the Partnership’s determination of the aggregate number of Class B Units which each holder of Incentive Distribution Rights will be entitled to receive.

(c)    The holder or holders of the Incentive Distribution Rights will be entitled to receive the Aggregate Quantity of Class B Units and related additional General Partner Units on the fifteenth Business Day after receipt by the Partnership of the Reset Notice, and the Partnership shall issue Certificates for the Class B Units to the holder or holders of the Incentive Distribution Rights; provided, however , that the issuance of Class B Units to the holder or holders of the Incentive Distribution Rights shall not occur prior to the approval of the listing or admission for trading of the Common Units into which the Class B Units are convertible pursuant to Section 5.11(f) by the principal National Securities Exchange upon which the Common Units are then listed or admitted for trading if any such approval is required pursuant to the rules and regulations of such National Securities Exchange.

(d)    If the principal National Securities Exchange upon which the Common Units are then traded has not approved the listing or admission for trading of the Common Units into which the Class B Units are convertible pursuant to Section 5.11(f) on or before the 30th calendar day following the Partnership’s receipt of the Reset Notice and such approval is required by the rules and regulations of such National Securities Exchange, then the holder of the Incentive Distribution Rights (or, if there is more than one holder of the Incentive Distribution Rights, the holders of a majority in interest of the Incentive Distribution Rights) shall have the right to either rescind the IDR Reset Election or elect to receive other Partnership Securities having such terms as the General Partner may approve, with the approval of the Special Committee, that will provide (i) the same economic value, in the aggregate, as the Aggregate Quantity of Class B Units would have had at the time of the Partnership’s receipt of the Reset Notice, as determined by the General Partner, and (ii) for the subsequent conversion of such Partnership Securities into Common Units within not

more than 12 months following the Partnership’s receipt of the Reset Notice upon the satisfaction of one or more conditions that are reasonably acceptable to the holder of the Incentive Distribution Rights (or, if there is more than one holder of the Incentive Distribution Rights, the holders of a majority in interest of the Incentive Distribution Rights).

(e)    The Minimum Quarterly Distribution, First Target Distribution, Second Target Distribution and Third Target Distribution shall be adjusted at the time of the issuance of Common Units or other Partnership Securities pursuant to this Section 5.11 such that (i) the Minimum Quarterly Distribution shall be reset to equal to the average cash distribution amount per Common Unit for the two Quarters immediately prior to the Partnership’s receipt of the Reset Notice (the “ Reset MQD ”), (ii) the First Target Distribution shall be reset to equal 115% of the Reset MQD, (iii) the Second Target Distribution shall be reset to equal to 125% of the Reset MQD and (iv) the Third Target Distribution shall be reset to equal 150% of the Reset MQD.

(f)    Any holder of Class B Units shall have the right to elect, by giving written notice to the General Partner, to convert all or a portion of the Class B Units held by such holder, at any time following the first anniversary of the issuance of such Class B Units, into Common Units on a one-for-one basis, such conversion to be effective on the second Business Day following the General Partner’s receipt of such written notice.

(g)    A Class B Unit that has, pursuant to Section 5.11(f), converted into a Common Unit (a “ Converted Class B Unit ”) shall be subject to the provisions of Section 6.7(a) and Section 6.7(b).

Section 5.12     Establishment of Class C Units .

(a)    The General Partner hereby designates and creates a series of Limited Partner Interests to be designated as “Class C Units,” initially consisting of a total of 10,913,853 Class C Units and such additional Class C Units as may be issued pursuant to the provisions of 5.12(d), having the terms and conditions set forth herein.

(b)    The holders of the Class C Units shall have rights upon dissolution and liquidation of the Partnership, including the right to share in any liquidating distributions pursuant to Section 12.4, in accordance with Article XII of this Agreement.

(c)     Conversion of Class C Units .

(i)    Immediately before the close of business on the Conversion Date (which shall be the date that is the earlier of (x) December 31, 2017, unless extended by Anadarko in its sole discretion by written notice to the Partnership of such extended date, and (y) the date on which the Partnership delivers notice to the holders of the Class C Units that the Class C Units have converted (which notice shall be delivered upon the determination of the General Partner), the Class C Units shall automatically convert into Common Units on a one-for-one basis.

(ii)    Upon conversion, the rights of a holder of Converted Class C Units as holder of Class C Units shall cease with respect to such Converted Class C Units, including any rights under this Agreement with respect to holders of Class C Units, and such Person shall continue to be a Limited Partner and have the rights of a holder of Common Units under this Agreement. All Class C Units shall, upon the Conversion Date, be deemed to be transferred to, and cancelled by, the Partnership in exchange for the Common Units into which the Class C Units converted.

(iii)    The Partnership shall pay any documentary, stamp or similar issue or transfer taxes or duties relating to the issuance or delivery of Common Units upon conversion of the Class C Units. However, the holder shall pay any tax or duty which may be payable relating to any transfer involving the issuance or delivery of Common Units in a name other than the holder’s name. The Transfer Agent may refuse to deliver a Certificate representing Common Units being issued in a name other than the holder’s name until the Transfer Agent receives a sum sufficient to pay any tax or duties which will be due because the shares are to be issued in a name other than the holder’s name. Nothing herein shall preclude any tax withholding required by law or regulation.

(iv)    (A)    Except as otherwise provided in Section 5.8, the Partnership shall keep free from preemptive rights a sufficient number of Common Units to permit the conversion of all outstanding Class C Units into Common Units to the extent provided in, and in accordance with, this Section 5.12(c).

(B)    All Common Units delivered upon conversion of the Class C Units shall be newly issued, shall be duly authorized and validly issued, and shall be free from preemptive rights (except as otherwise provided in Section 5.8) and free of any lien or adverse claim.

(C)    The Partnership shall comply with all applicable securities laws regulating the offer and delivery of any Common Units upon conversion of Class C Units and, if the Common Units are then listed or quoted on the New York Stock Exchange, or any other National Securities Exchange or other market, shall list or cause to have quoted and keep listed and quoted the Common Units issuable upon conversion of the Class C Units to the extent permitted or required by the rules of such exchange or market.

(D)    Notwithstanding anything herein to the contrary, nothing herein shall give to any holder of Class C Units any rights as a creditor in respect of its right to conversion.

(v)    Upon the issuance of the Common Units delivered upon conversion of the Class C Units (other than Class C Units with respect to which an additional Capital Contribution was previously made pursuant to Section 5.2(b)), the General Partner may, in exchange for a proportionate number of General Partner Units, make additional Capital Contributions in an amount equal to the product obtained by multiplying (i) the quotient determined by dividing (A) the General Partner’s Percentage Interest by (B) a percentage

equal to 100% less the General Partner’s Percentage Interest times (ii) the aggregate Issue Price for the Class C Units (including, for the avoidance of doubt, PIK C Units issued prior to the Conversion Date).

(d)     Class C Distributions .

(i)    Each Class C Unit shall receive a distribution, in accordance with the provisions of this Section 5.12(d), calculated as provided below based on the amount paid in respect of each Common Unit pursuant to Sections 6.4 and 6.5 (the amount to be so paid, the “ Distribution Amount ”). Each distribution payable in respect of a Class C Unit (the “ Class C Unit Distribution ”) shall be paid in PIK C Units. The number of PIK C Units to be issued in a Class C Unit Distribution shall be the quotient of (A) the Distribution Amount divided by (B) an amount equal to 94.0% of the VWAP Price as of the date the corresponding distributions are made in respect of Common Units pursuant to Section 6.4 or 6.5. The first such distribution on Class C Units shall be paid in the calendar quarter following the calendar quarter in which the Class C Units were issued under the Unit Purchase Agreement. Such first distribution shall be prorated based on the number of days during such quarter that the Class C Units were outstanding, such that the number of PIK C Units to be issued in such first Class C Unit Distribution shall equal the amount calculated above in this Section 5.12(d)(i) multiplied by the quotient determined by dividing (A) the number of days between the date on which the Class C Units were issued and the end of such calendar quarter by (B) the total number of days in such calendar quarter. In all cases, instead of issuing any fractional PIK C Units, the Partnership shall round the number of PIK C Units issuable to a holder of Class C Units down to the next lower whole PIK C Unit and pay cash in lieu of such fractional units, or at the Partnership’s option, the Partnership may round the number of PIK C Units issuable to a holder of Class C Units up to the next higher whole PIK C Unit. For purposes of determining fractional PIK C Units otherwise issuable to a particular holder, all PIK C Units attributable to all Class C Units of such holder, whether held in one or multiple accounts, shall be aggregated so that less than one fractional PIK C Unit is issuable to any one holder. For the avoidance of doubt, no distribution shall be payable in respect of the Incentive Distribution Rights under Section 6.4 or 6.5 by virtue of the payment of the Class C Unit Distribution.

(ii)    Notwithstanding anything in this Section 5.12(d) to the contrary, with respect to Class C Units that are converted into Common Units, the holder thereof shall not be entitled to a Class C Unit Distribution and a Common Unit distribution with respect to the same period, but shall be entitled only to the distribution to be paid based upon the class of Units held as of the close of business on the applicable Record Date. If the Class C Conversion Date occurs between a Record Date for a Class C Unit Distribution and the related payment date, a holder of the Class C Units on such Record Date shall receive, in lieu of the PIK C Units that would otherwise have been issuable to such holder, a distribution of Common Units equal in number to the number of PIK C Units that would have been payable to such holder had the Class C Conversion Date not occurred, and such Common Units will otherwise be issued in accordance with the provisions of this Section 5.12(d) relating to the issuance of a PIK C Unit.

(iii)    When any PIK C Units are payable to a holder of Class C Units pursuant to this Section 5.12, the Partnership shall issue the PIK C Units to such holder on the date the corresponding distributions are made in respect of Common Units pursuant to Section 6.4 or 6.5, as applicable (the date of issuance of such PIK C Units, the “ PIK C Payment Date ”). On the PIK C Payment Date, the Partnership shall issue to such holder of Class C Units a certificate or certificates for the number of PIK C Units to which such holder of Class C Units shall be entitled or, at the request of such holder of Class C Units, a notation in book entry form in the books of the Transfer Agent.

(iv)    For purposes of maintaining Capital Accounts under Section 5.5, if the Partnership distributes one or more PIK C Units to a holder of Class C Units, (i) the Partnership shall be treated as distributing cash to such holder of Class C Units equal to the Distribution Amount, and (ii) the holder of Class C Units shall be deemed to have contributed to the Partnership in exchange for such newly issued PIK C Units an amount of cash equal to the Distribution Amount, less the amount of any cash distributed by the Partnership in lieu of fractional PIK C Units.

(e)    The Class C Units will have such voting rights pursuant to this Agreement as such Class C Units would have if they were Common Units that were then outstanding and shall vote together with the Common Units as a single class, except that Class C Units owned by the General Partner and its Affiliates shall not be entitled to vote, approve or consent on matters if Common Units owned by the General Partner and its Affiliates are excluded from voting, approving or consenting on such matters, and except that the Class C Units shall be entitled to vote as a separate class on any matter on which Unitholders are entitled to vote that adversely affects the rights or preferences of the Class C Units in relation to other classes of Partnership Interests in any material respect or as required by law. The approval of a majority (or such other percentage as set forth in this Agreement) of the Class C Units shall be required to approve any matter for which the holders of the Class C Units are entitled to vote as a separate class.

(f)    Each Class C Unit and each Class C Unit that has converted into a Common Unit shall be subject to the provisions of Sections 5.5(c)(iii), 5.5(d), 6.1(d)(x)(C), 6.7(c) and 6.7(d).

Section 5.13     Establishment of Series A Preferred Units.

(a)     General . The Partnership hereby designates and creates a series of Units to be designated as “Series A Convertible Preferred Units” (the “ Series A Preferred Units ”), having the same rights, preferences and privileges, and subject to the same duties and obligations, as the Common Units, except as set forth in this Section 5.13 and in Sections 5.5, 6.1 and 12.4. However, in the event of any conflict between the rights, preferences, privileges, duties and obligations of the Common Units or any other class of Partnership Securities as set forth in this Agreement and the provisions of this Section 5.13 and Sections 5.5, 6.1 and 12.4 that specifically set forth the rights, preferences, privileges, duties and obligations of the Series A Preferred Units, such specific provisions shall control.

(b)     Rights of Series A Preferred Units . The Series A Preferred Units shall have the following rights, preferences and privileges and the Series A Preferred Unitholders shall be subject to the following duties and obligations:

(i)     Distributions .

(A)    Commencing with the Quarter ending on March 31, 2016, the Record Holders of the Series A Preferred Units as of an applicable Record Date for any Quarter shall be entitled to receive cumulative distributions in respect of such Quarter equal to the sum of (1) the Series A Distribution Amount and (2) any Series A Unpaid Cash Distributions (collectively, a “ Series A Quarterly Distribution ”), prior to any other distributions made in respect of any other Partnership Interests pursuant to Section 6.4 or Section 6.5, in the amount set forth in this Section 5.13(b)(i)(A) in respect of each outstanding Series A Preferred Unit. All such distributions shall be paid quarterly in cash within forty-five (45) days after the end of each Quarter (each such payment date, a “ Series A Distribution Payment Date ”).  If the Partnership establishes a Record Date for any distribution to be made by the Partnership on other Partnership Interests pursuant to Sections 6.4 or Section 6.5 in respect of any Quarter, then the Record Date established pursuant to this Section 5.13(b)(i) for a Series A Quarterly Distribution in respect of such Quarter shall be the same Record Date. For the avoidance of doubt, subject to Section 5.13(b)(i)(D), the Series A Preferred Units shall not be entitled to any distributions made pursuant to Section 6.4 for any Quarter so long as the Series A Quarterly Distribution has been declared and paid on the Series A Preferred Units with respect to such Quarter.

(B)    If the Partnership fails to pay in full the Series A Distribution Amount of any Series A Quarterly Distribution in cash when due for any Quarter, then from and after the first date of such failure and continuing until such failure is cured by payment in full in cash of all such arrearages, (1) the amount of such unpaid cash distributions (“ Series A Unpaid Cash Distributions ”) unless and until paid will accrue and accumulate from and including the first day of the Quarter immediately following the Quarter in respect of which such payment is due until paid in full and (2) the Partnership shall not be permitted to, and shall not, declare or make any distributions in respect of any Series A Junior Interests (including, for the avoidance of doubt, with respect to the Quarter for which the Partnership first failed to pay in full the Series A Distribution Amount of any Series A Quarterly Distribution in cash when due).

(C)    The aggregate Series A Distribution Amount shall be paid out of Available Cash with respect to the applicable Quarter that is deemed to be Operating Surplus prior to making any distribution pursuant to Sections 6.4 or 6.5. To the extent that any portion of a Series A Quarterly Distribution with respect to any Quarter exceeds the amount of Available Cash that is deemed to be Operating Surplus for such Quarter, the amount of cash equal to the Available Cash for such Quarter will be paid to the Series A Preferred Unitholders Pro Rata and the balance of such Series

A Quarterly Distribution shall be unpaid and shall constitute an arrearage and shall accrue and accumulate as set forth in Section 5.13(b)(i)(B).

(D)    Notwithstanding anything in this Section 5.13(b)(i) to the contrary, with respect to any Series A Preferred Unit that is converted into a Common Unit, the Record Holder thereof shall not be entitled to a distribution in respect of such Series A Preferred Unit and a distribution in respect of such Common Unit with respect to the same period, but shall be entitled only to the distribution to be paid based upon the class of Units held as of the close of business on the applicable Record Date. For the avoidance of doubt, if a Series A Conversion Date occurs prior to the close of business on a Record Date for payment of a distribution on the Common Units, the applicable Record Holder of Series A Preferred Units shall receive, with respect to any Series A Preferred Units that have converted into Common Units, only the distribution in respect of such Common Units with respect to such period.

(E)    Notwithstanding anything in Article VI to the contrary, the holders of the Incentive Distribution Rights shall not be entitled to receive distributions or allocations of income or gain that correspond or relate to amounts distributed or allocated to Unitholders in respect of Series A Preferred Units.

(ii)     Issuance of the Series A Preferred Units. Subject to Section 5.13(b)(iv), the Series A Preferred Units shall be issued by the Partnership pursuant to the terms and conditions of the Series A Purchase Agreement.

(iii)     Voting Rights .

(A)    Except as provided in Section 5.13(b)(iii)(B), the Outstanding Series A Preferred Units shall have voting rights that are identical to the voting rights of the Common Units and shall vote with the Common Units, Class B Units and Class C Units as a single class, so that each Outstanding Series A Preferred Unit will be entitled to one vote for each Common Unit into which such Series A Preferred Unit is then convertible at the then applicable Series A Conversion Rate (or, if the Series A Preferred Units are not then convertible, assuming that such Series A Preferred Units are convertible at the then applicable Series A Conversion Rate) on each matter with respect to which each Record Holder of a Common Unit is entitled to vote. Each reference in this Agreement to a vote of Record Holders of Common Units shall be deemed to be a reference to the Record Holders of Common Units and Series A Preferred Units on an “as if” converted basis, and the definition of “Unit Majority” shall correspondingly be construed to mean at least a majority of the Common Units and the Series A Preferred Units, as well as the Class B Units and the Class C Units, as applicable, on an “as if” converted basis, voting together as a single class during any period in which any Series A Preferred Units are Outstanding.

(B)    Notwithstanding any other provision of this Agreement, in addition to all other requirements imposed by Delaware law, and all other voting rights granted under this Agreement, the affirmative vote of the Record Holders of the Series A

Required Voting Percentage, shall be required for any amendment (excluding any amendment of a ministerial or administrative nature) to this Agreement or the Certificate of Limited Partnership (including by merger or otherwise) that is adverse to any of the rights, preferences and privileges of the Series A Preferred Units. Without limiting the generality of the preceding sentence, any action shall be deemed to adversely affect the Record Holders of the Series A Preferred Units if such action would:

(1)    reduce the Series A Distribution Amount, change the form of payment of distributions on the Series A Preferred Units, defer the date from which distributions on the Series A Preferred Units will accrue, cancel accrued and unpaid distributions on the Series A Preferred Units, or change the seniority rights of the Series A Preferred Unitholders as to the payment of distributions in relation to the Unitholders of any other class or series of Units;

(2)    reduce the amount payable or change the form of payment to the Record Holders of the Series A Preferred Units upon the voluntary or involuntary liquidation, dissolution or winding up, or sale of all or substantially all of the assets, of the Partnership, or change the seniority of the liquidation preferences of the Record Holders of the Series A Preferred Units in relation to the rights upon liquidation of the holders of any other class or series of Units; or

(3)    make the Series A Preferred Units redeemable or convertible at the option of the Partnership other than as set forth herein.

(C)    Notwithstanding anything to the contrary in this Section 5.13(b)(iii), except as contemplated by Section 5.13(b)(iii)(A), in no event shall the consent of the Series A Preferred Unitholders, as a separate class, be required in connection with any Partnership Restructuring Event. For the avoidance of doubt, the foregoing shall not limit the voting rights of any Series A Preferred Unitholder in connection with the vote of Record Holders of Common Units and Series A Preferred Units together as a single class.

(D)    Upon the occurrence of a Series A Trigger Event, the General Partner shall notify the Series A Preferred Unitholders of the occurrence thereof, whereupon the Series A Preferred Unitholders, acting as a group and by majority vote of the Outstanding Series A Preferred Units, shall have the right, exercisable by the delivery of written notice delivered to the General Partner, to appoint a Series A Board Observer to the Board of Directors in accordance with the Series A Board Observation Agreement; provided that upon payment of all Series A Unpaid Cash Distributions, any such Series A Board Observer shall cease to have observation rights resulting from such Series A Unpaid Cash Distributions unless and until a subsequent Series A Trigger Event occurs.

(E)    Notwithstanding any other provision of this Agreement, in addition to all other voting rights granted under this Agreement, the Partnership shall not declare or pay any distribution from Capital Surplus without the affirmative vote of the Record Holders of the Series A Required Voting Percentage.

(iv)     No Series A Senior Securities; Series A Parity Securities . Other than issuances contemplated by the Series A Purchase Agreement, the Partnership shall not, without the affirmative vote of the Record Holders of the Series A Required Voting Percentage, issue any (A) Series A Senior Securities (or amend the provisions of any class of Partnership Securities to make such class of Partnership Securities a class of Series A Senior Securities), (B) additional Series A Preferred Units, except that the Partnership may issue additional Series A Preferred Units without the affirmative vote of the Series A Required Voting Percentage so long as (1) the proceeds from any such issuances collectively and the issuance of the Series A Preferred Units pursuant to the Series A Purchase Agreement in the aggregate do not exceed $687,500,000 (net of any applicable transaction fees), (2) any such issuance is complete prior to the six-month anniversary of the Series A Issuance Date and (3) any such issuance is on terms that are, on the whole, no less favorable to the Partnership than the Series A Preferred Units issued pursuant to the Series A Purchase Agreement, as determined by the Board of Directors (as set forth in subclause (3) to this Clause (B), the “ Issuance Test ”), or (C) Series A Parity Securities (or amend the provisions of any class of Partnership Securities to make such class of Partnership Securities a class of Series A Parity Securities); provided that, without the consent of the Record Holders of the Series A Required Voting Percentage, the Partnership may issue up to an aggregate $1,000,000,000 of Series A Parity Securities at any time after the Series A Closing Date; provided , however , any issuance of convertible Series A Parity Securities prior to the six-month anniversary of the Series A Closing Date is subject to the Issuance Test. The Partnership may, without the consent of the Record Holders of Outstanding Series A Preferred Units, issue Series A Junior Interests in an unlimited amount.

(v)     Certificates .

(A)    If requested by a Series A Preferred Unitholder, the Series A Preferred Units shall be evidenced by certificates in such form as the Board of Directors may approve and, subject to any applicable legal, regulatory and contractual requirements or any other limitations set forth in this Section 5.13, may be assigned or transferred in a manner identical to the assignment and transfer of other Units. Any certificates evidencing Series A Preferred Units shall be separately identified and shall not bear the same CUSIP number as any certificates evidencing Common Units.

(B)    Any certificate(s) representing the Series A Preferred Units may be imprinted with a legend in substantially the following form:

“NEITHER THE OFFER NOR SALE OF THESE SECURITIES HAS BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. THESE SECURITIES MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE

ABSENCE OF A REGISTRATION STATEMENT IN EFFECT WITH RESPECT TO THE SECURITIES UNDER SUCH ACT OR PURSUANT TO AN EXEMPTION FROM REGISTRATION THEREUNDER AND, IN THE CASE OF A TRANSACTION EXEMPT FROM REGISTRATION, UNLESS SOLD PURSUANT TO RULE 144 UNDER SUCH ACT OR THE PARTNERSHIP HAS RECEIVED DOCUMENTATION REASONABLY SATISFACTORY TO IT THAT SUCH TRANSACTION DOES NOT REQUIRE REGISTRATION UNDER SUCH ACT. THIS SECURITY IS SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER SET FORTH IN THE SECOND AMENDED AND RESTATED LIMITED PARTNERSHIP AGREEMENT OF THE PARTNERSHIP, DATED AS OF MARCH 14, 2016, A COPY OF WHICH MAY BE OBTAINED FROM THE PARTNERSHIP AT ITS PRINCIPAL EXECUTIVE OFFICES.”

(vi)     Conversion.

(A)     At the Option of the Series A Preferred Unitholders .  Beginning with the earlier of (i) the second anniversary of the Series A Issuance Date, and (ii) immediately prior to the liquidation, dissolution and winding up of the Partnership under Section 12.4, the Series A Preferred Units owned by any Series A Preferred Unitholder shall be convertible, in whole or in part, at any time and from time to time upon the request of such Series A Preferred Unitholder, but not more than once per Quarter, into a number of Common Units determined by multiplying the number of Series A Preferred Units to be converted by the Series A Conversion Rate; provided, however , that the Partnership shall not be obligated to honor any such conversion request if such conversion request does not involve an underlying value of Common Units of at least $50,000,000 based on the Closing Price of Common Units on the Trading Day immediately preceding the Series A Conversion Notice Date (or such lesser amount to the extent such exercise covers all of such Series A Preferred Unitholder’s Series A Preferred Units). Immediately upon the effectiveness of any conversion of Series A Preferred Units, all rights of the Series A Converting Unitholder in respect thereof shall cease, including, without limitation, any further accrual of distributions, and such Series A Converting Unitholder thereafter shall be treated for all purposes as the owner of Common Units. Fractional Common Units shall not be issued to any person pursuant to this Section 5.13(b)(vi)(A) (each fractional Common Unit shall be rounded down with the remainder being paid an amount in cash based on the Closing Price of Common Units on the Trading Day immediately preceding such date of conversion).

(B)     At the Option of the Partnership. At any time following the third anniversary of the Series A Issuance Date, the Partnership, in the General Partner’s sole discretion, shall have the option at any time, but not more than once per Quarter, to convert all or any portion of the Series A Preferred Units then Outstanding into a

number of Common Units determined by multiplying the number of Series A Preferred Units to be converted by the Series A Conversion Rate. Fractional Common Units shall not be issued to any person pursuant to this Section 5.13(b)(vi)(B) (each fractional Common Unit shall be rounded down with the remainder being paid an amount in cash based on the Closing Price of Common Units on the Trading Day immediately preceding such date of conversion). Notwithstanding the foregoing, in order for the Partnership to exercise such option,

(1)    the Closing Price of the Common Units must be equal to or greater than one hundred fifty percent (150%) of the Series A Issue Price for twenty (20) Trading Days out of the thirty (30) Trading Day period immediately preceding the date the Company furnishes the Series A Forced Conversion Notice,

(2)    the average daily trading volume of the Common Units on the National Securities Exchange on which the Common Units are then listed or admitted to trading must be equal to or exceed 200,000 (as such amount may be adjusted to reflect any Unit split, combination or similar event) for the twenty (20) Trading Day period immediately preceding the date the Company furnishes the Series A Forced Conversion Notice;

(3)    the Partnership must have an effective registration statement on file with the Commission covering resales of the underlying Common Units to be received upon any such conversion, and

(4)    no Series A Trigger Event shall have occurred that is continuing;

provided , in each case, that each such conversion by the Partnership shall be for an aggregate amount of Series A Preferred Units involving an underlying value of Common Units of at least $100,000,000 based on the Closing Price of Common Units on the Trading Day immediately preceding the date of such conversion (or such lesser amount if such amount includes all then Outstanding Series A Preferred Units) and shall be allocated among the Series A Preferred Unitholders on a Pro Rata basis or on such other basis as may be agreed upon by the Series A Preferred Unitholders.

(C)     Conversion Notice.

(1)    To convert Series A Preferred Units into Common Units pursuant to Section 5.13(b)(vi)(A), the Series A Converting Unitholder shall give written notice (a “ Series A Conversion Notice ,” and the date such notice is received, a “ Series A Conversion Notice Date ”) to the Partnership stating that such Series A Unitholder elects to so convert Series A Preferred Units and shall state or include therein with respect to Series A Preferred Units to be converted pursuant to Section 5.13(b)(vi)(A) the following: (a) the number of Series A Preferred Units to be converted, and (b) if a Certificate has been

issued for such Series A Preferred Units, the Certificate(s) evidencing the Series A Preferred Units to be converted and duly endorsed.

(2)    To convert Series A Preferred Units into Common Units pursuant to Section 5.13(b)(vi)(B), the Partnership shall give written notice (a “ Series A Forced Conversion Notice ,” and the date such notice is received, a “ Series A Forced Conversion Notice Date ”) to each Record Holder of Series A Preferred Units stating that the Partnership elects to force conversion of such Series A Preferred Units pursuant to Section 5.13(b)(vi)(B). The Series A Conversion Units shall be issued in the name of the Record Holder of such Series A Preferred Units.

(D)     Timing; Certificates . If a Series A Conversion Notice is delivered by a Series A Unitholder to the Partnership or a Series A Forced Conversion Notice is delivered by the Partnership to a Series A Unitholder, each in accordance with Section 5.13(b)(vi)(C), the Partnership shall issue the Series A Conversion Units no later than seven (7) days after the Series A Conversion Notice Date or the Series A Forced Conversion Notice Date, as the case may be, occurs (any date of issuance of such Common Units, a “ Series A Conversion Date ”). On the Series A Conversion Date, if the Transfer Agent is participating in the Depository’s Fast Automated Securities Transfer program, the Partnership shall use its commercially reasonable efforts to cause its Transfer Agent to electronically transmit the Series A Conversion Units issuable upon conversion to such Series A Unitholder (or designated recipient(s)), by crediting the account of the Series A Unitholder (or designated recipient(s)) prime broker with the Depository through its Deposit Withdrawal Agent Commission system. If the Transfer Agent is not participating in the Depository’s Fast Automated Securities Transfer program, or if requested by such Series A Unitholder, the Partnership shall issue to such Series A Unitholder (or designated recipient(s)) a Certificate or Certificates for the number of Series A Conversion Units to which such Series A Unitholder shall be entitled. The parties agree to coordinate with the Depository to accomplish this objective. Upon issuance of Series A Conversion Units to the Series A Converting Unitholder, all rights under the converted Series A Preferred Units shall cease, and such Series A Converting Unitholder shall be treated for all purposes as the Record Holder of such Series A Conversion Units.

(E)     Distributions, Combinations, Subdivisions and Reclassifications by the Partnership . If, after the Series A Issuance Date, the Partnership (i) makes a distribution on its Common Units payable in Common Units or another Partnership Interest, (ii) subdivides or splits its outstanding Common Units into a greater number of Common Units, (iii) combines or reclassifies its Common Units into a smaller number of Common Units or (iv) issues by reclassification of its Common Units any Partnership Interests (including any reclassification in connection with a merger, consolidation or business combination in which the Partnership is the surviving Person), in each case other than in connection with a Series A Change of Control (which shall be governed by Section 5.13(b)(vii)), then the Series A Conversion Rate

in effect at the time of the Record Date for such distribution or the effective date of such subdivision, split, combination or reclassification shall be proportionately adjusted so that the conversion of the Series A Preferred Units after such time shall entitle each Series A Unitholder to receive the aggregate number of Common Units (or any Partnership Interests into which such Common Units would have been combined, consolidated, merged or reclassified pursuant to clauses (iii) and (iv) above) that such Series A Unitholder would have been entitled to receive if the Series A Preferred Units had been converted into Common Units immediately prior to such Record Date or effective date, as the case may be, and in the case of a merger, consolidation or business combination in which the Partnership is the surviving Person, the Partnership shall provide effective provisions to ensure that the provisions in this Section 5.13 relating to the Series A Preferred Units shall not be abridged or amended and that the Series A Preferred Units shall thereafter retain the same powers, preferences and relative participating, optional and other special rights, and the qualifications, limitations and restrictions thereon, that the Series A Preferred Units had immediately prior to such transaction or event. An adjustment made pursuant to this Section 5.13(b)(vi)(E) shall become effective immediately after the Record Date in the case of a distribution and shall become effective immediately after the effective date in the case of a subdivision, combination, reclassification (including any reclassification in connection with a merger, consolidation or business combination in which the Partnership is the surviving Person) or split. Such adjustment shall be made successively whenever any event described above shall occur.

(F)     No Adjustments for Certain Items .  Notwithstanding any of the other provisions of this Section 5.13(b)(vi), no adjustment shall be made to the Series A Conversion Rate pursuant to Section 5.13(b)(vi)(E) as a result of any of the following:

(1)    any issuance of Partnership Securities for in exchange for cash;

(2)    any issuance of additional Partnership Securities issued in connection with distributions paid in kind;

(3)    any grant of Common Units or options, warrants or rights to purchase or receive Common Units or the issuance of Common Units upon the exercise or vesting of any such options, warrants or rights in respect of services provided to or for the benefit of the Partnership or its Subsidiaries, under compensation plans and agreements approved by the General Partner (including any long-term incentive plan); or

(4)    any issuance of Common Units as all or part of the consideration to effect (i) the closing of any acquisition by the Partnership of assets or equity interests of a third party in an arm’s-length transaction, (ii) closing of any acquisition by the Partnership of assets or equity interests of Anadarko or any of its Affiliates or (iii) the consummation of a merger,

consolidation or other business combination of the Partnership with another entity in which the Partnership survives and the Common Units remain Outstanding to the extent any such transaction set forth in clause (i), (ii) or (iii) above is validly approved by the vote or consent of the General Partner.

Notwithstanding anything in this Agreement to the contrary, whenever the issuance of a Partnership Interest or other event would require an adjustment to the Series A Conversion Rate under one or more provisions of this Agreement, only one adjustment shall be made to the Series A Conversion Rate in respect of such issuance or event.

(vii)     Series A Change of Control .

(A)    Subject to Section 5.13(b)(vi)(B), in the event of a Series A Cash COC Event, the Outstanding Series A Preferred Units shall be automatically converted, without requirement of any action of the Series A Preferred Unitholders, into Common Units immediately prior to the closing of the Series A Cash COC Event at a conversion ratio equal to the greater of (1) the then applicable Series A Conversion Rate (or, if the Series A Preferred Units are not then convertible, assuming that such Series A Preferred Units are convertible at the then applicable Series A Conversion Rate) and (2) the quotient of (i) the product of (a) the Series A Issue Price together with accrued but unpaid distributions on the Series A Preferred Units, multiplied by (b) the Series A Cash COC Conversion Premium, divided by (ii) the volume-weighted average price of the Common Units for the thirty (30) Trading Day period ending immediately prior to the date of execution and public announcement of the Series A Cash COC Event; provided that the ratio contemplated by clause (2) above shall not exceed a ratio resulting in a value per Series A Preferred Unit (based on the consideration payable to Record Holders of Common Units in such Series A Cash COC Event) equal to (i) 120% of the Series A Issue Price in the case of a Series A Change of Control occurring on or prior to the first anniversary of the Series A Issuance Date, (ii) 130% of the Series A Issue Price in the case of a Series A Change of Control occurring after the first anniversary of the Series A Issuance Date but on or prior to the second anniversary of the Series A Issuance Date, and (iii) 140% of the Series A Issue Price in the case of a Series A Change of Control occurring after the second anniversary of the Series A Issuance Date but on or prior to the third anniversary of the Series A Issuance Date.

(B)    Promptly upon entry into definitive agreements that provide for a Series A Change of Control (other than a Series A Cash COC Event), if the Partnership has not issued a press release or other widely disseminated public statement regarding the entry into such definitive agreements, the Partnership shall provide written notice thereof to the Series A Unitholders. Subject to Section 5.13(b)(vi)(B), if a Series A Change of Control (other than a Series A Cash COC Event) occurs, then each Series A Preferred Unitholder, with respect to all but not less than all of its Series A Preferred Units, by notice given to the Partnership within ten (10) Business Days of the date the Partnership provides written notice of the execution of definitive agreements that

provide for such Series A Change of Control, shall be entitled to elect one of the following (with the understanding that any Series A Preferred Unitholder who fails to timely provide notice of its election to the Partnership shall be deemed to have elected the option set forth in sub-clause (1) below):

(1)    convert all, but not less than all, Outstanding Series A Preferred Units into Common Units, at the then-applicable Series A Conversion Rate, subject to payment of any accrued but unpaid distributions to the date of conversion, in accordance with Section 5.13(b)(vi);

(2)    if the Partnership will not be the surviving entity of such Series A Change of Control or the Partnership will be the surviving entity but its Common Units will cease to be listed or admitted to trading on a National Securities Exchange, require the Partnership to use its commercially reasonable efforts to deliver or to cause to be delivered to the Series A Preferred Unitholders, in exchange for their Series A Preferred Units upon such Series A Change of Control, a security in the surviving entity that has substantially similar rights, preferences and privileges as the Series A Preferred Units, including, for the avoidance of doubt, the right to distributions equal in amount and timing to those provided in Section 5.13(b)(i) and a conversion rate proportionately adjusted such that the conversion of such security in the surviving entity immediately following the Series A Change of Control would entitle the Record Holder to the number of common securities of such surviving entity (together with a number of common securities of equivalent value to any other assets received by Common Unitholders in such Series A Change of Control) which, if a Series A Preferred Unit had been converted into Common Units immediately prior to such Series A Change of Control, such Record Holder would have been entitled to receive immediately following such Series A Change of Control (such security in the surviving entity, a “ Series A Substantially Equivalent Unit ”);  provided ,  however , that, if the Partnership is unable to deliver or cause to be delivered Series A Substantially Equivalent Units to any Series A Preferred Unitholder in connection with such Series A Change of Control, each Series A Preferred Unitholder shall be entitled to convert the Series A Preferred Units held by such Series A Preferred Unitholder immediately prior to such Series A Change of Control into a number of Common Units at a conversion ratio equal to the quotient of:

(3)    if the Partnership is the surviving entity of such Series A Change of Control, continue to hold Series A Preferred Units; or

(4)    require the Partnership to redeem the Series A Preferred Units at a price per Series A Preferred Unit equal to 101% of the Series A Issue Price plus accrued and unpaid distributions to the date of such redemption. Any redemption pursuant to this sub-clause (4) shall, in the sole discretion of the General Partner, be paid in cash and/or Common Units. If all or any portion of such redemption is to be paid in Common Units, the Common Units to be issued shall be valued at 95% of the volume-weighted average price of the Common Units for the thirty (30) Trading Day period ending on the fifth Trading Day immediately prior to the Series A Change of Control. No later than three Trading Days prior to the consummation of the related Series A Change of Control, the Partnership shall deliver a written notice to the Record Holders of the Series A Preferred Units stating the date on which the Series A Preferred Units will be redeemed and the Partnership’s computation of the amount of cash or Common Units to be received by the Record Holder upon redemption of such Series A Preferred Units. No later than 10 Business Days following the consummation of such Series A Change of Control, the Partnership shall remit the applicable cash or Common Unit consideration to the Record Holders of then Outstanding Series A Preferred Units. The Record Holders shall deliver to the Partnership any Certificates representing the Series A Preferred Units as soon as practicable following the redemption. Record Holders of the Series A Preferred Units shall retain all of the rights and privileges thereof unless and until the consideration due to them as a result of such redemption shall be paid in full in cash or Common Units, as applicable. After any such redemption, any such redeemed Series A Preferred Unit shall no longer constitute an issued and Outstanding Limited Partner Interest.

(viii)     Series A Preferred Unit Transfer Restrictions.

(A)    Notwithstanding any other provision of this Section 5.13(b)(viii), each Series A Purchaser shall be permitted to transfer any Series A Preferred Units owned by such Series A Purchaser to any of its Affiliates or to any other Series A Purchaser.

(B)    Without the prior written consent of the Partnership, except as specifically provided in this Agreement, each Series A Preferred Unitholder shall not, (a) during the period commencing on the Series A Issuance Date and ending on the first anniversary of the Series A Issuance Date, offer, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any of its Series A Preferred Units, (b) during the period commencing on the Series A Issuance Date and ending on the second anniversary of the Series A Issuance Date, directly or indirectly engage in any short sales or other derivative or hedging transactions with respect to the Series A Preferred Units, Common Units of the Partnership or common units representing limited partner interests in WGP that are designed to, or that might reasonably be expected to, result in the transfer to another, in whole or in part, any of the economic consequences of ownership of any Series A Preferred Units, (c) transfer any Series A Preferred Units to any non-U.S. resident individual, non-U.S. corporation or partnership, or any other non-U.S. entity, including any foreign governmental entity, including by means of any swap or other transaction or arrangement that transfers or that is designed to, or that might reasonably be expected to, result in the transfer to another, in whole or in part, any of the economic consequences of ownership of any Series A Preferred Units, regardless of whether any transaction described in clauses (a) through (c) above is to be settled by delivery of Series A Preferred Units, Common Units or other securities, in cash or otherwise, or (d) effect any transfer of Series A Preferred Units or Series A Conversion Units in a manner that violates the terms of this Agreement; provided, however , that such Series A Preferred Unitholder may pledge all or any portion of its Series A Preferred Units to any holders of obligations owed by the Series A Preferred Unitholders, including to the trustee for, or representative of, such holders. Notwithstanding the foregoing, any transferee receiving any Series A Preferred Units pursuant to this Section 5.13(b)(viii)(B) shall agree to the restrictions set forth in this Section 5.13(b)(viii)(B).

(C)    Following the first anniversary of the Series A Issuance Date, the Series A Purchasers or their permitted transferees may freely transfer Series A Preferred Units involving an underlying value of Common Units of at least $25,000,000 based on the Closing Price of Common Units on the Trading Day immediately preceding the date of such transfer (or such lesser amount if it (i) constitutes the remaining holdings of such Series A Preferred Unitholder or (ii) has been approved by the General Partner, in its sole discretion), subject to compliance with applicable securities laws and this Agreement.

(ix)     Fully Paid and Non-assessable . Any Series A Conversion Unit(s) delivered pursuant to this Section 5.13 shall be validly issued, fully paid and non-assessable (except as such non-assessability may be affected by matters described in Sections 17-303, 17-607 and 17-804 of the Delaware Act), free and clear of any liens, claims, rights or encumbrances other than those arising under the Delaware Act or this Agreement or created by the holders thereof.

(x)     Partnership Restructuring Event . Subject to Section 5.13(b)(vi)(B), if (A) a Partnership Restructuring Event occurs or the Partnership engages in any other recapitalization, reorganization, consolidation, merger, spin-off or other business combination (other than a Series A Change of Control) and (B) (1) the Partnership will not be the surviving entity of such Partnership Restructuring Event or other event or (2) the Partnership will be the surviving entity but its Common Units will cease to be listed or admitted to trading on a National Securities Exchange, the Partnership shall deliver or cause to be delivered to the Series A Preferred Unitholders, in exchange for their Series A Preferred Units upon consummation of such Partnership Restructuring Event or other event, a security in the surviving entity that has substantially similar rights, preferences and privileges as the Series A Preferred Units, including, for the avoidance of doubt, the right to distributions equal in amount and timing to those provided in Section 5.13(b)(i) and a conversion rate proportionately adjusted such that the conversion of such security in the surviving entity immediately following the Partnership Restructuring Event or such other event would entitle the holder to the number of common securities of such surviving entity (together with a number of common securities of equivalent value to any other assets received by Common Unitholders in such Partnership Restructuring Event or such other event) which, if a Series A Preferred Unit had been converted into Common Units immediately prior to such Partnership Restructuring Event or such other event, such Record Holder would have been entitled to receive immediately following such Partnership Restructuring Event or such other event.

(xi)     Notices . For the avoidance of doubt, the Partnership shall distribute to the Record Holders of Series A Preferred Units copies of all notices, materials, annual and quarterly reports, proxy statements, information statements and any other documents distributed generally to the Record Holders of Common Units of the Partnership, at such times and by such method as such documents are distributed to such Record Holders of such Common Units.

Section 5.14     Deemed Capital Contributions.

Consistent with the principles of Treasury Regulation Section 1.83-6(d), if any Partner (or its successor) transfers property (including cash) to or on behalf of any employee or other service provider of the Partnership Group and such Partner is not entitled to be reimbursed by (or otherwise elects not to seek reimbursement from) the Partnership for the value of such property, then for tax purposes, (x) such property shall be treated as having been contributed to the Partnership by such Partner and (y) immediately thereafter the Partnership shall be treated as having transferred such property to or on behalf of the employee or other service provider.

ARTICLE VI

ALLOCATIONS AND DISTRIBUTIONS

Section 6.1     Allocations for Capital Account Purposes .

For purposes of maintaining the Capital Accounts and in determining the rights of the Partners among themselves, the Partnership’s items of income, gain, loss and deduction (computed in accordance with Section 5.5(b)) for each taxable period shall be allocated among the Partners as provided herein below. As set forth in the definition of “Outstanding,” Restricted Common Units shall not be considered to be Outstanding Common Units for purposes of this Section 6.1 and references herein to Unitholders holding Common Units shall be to such Unitholders solely with respect to their Common Units other than Restricted Common Units.

(a)     Net Income. Net Income for each taxable period (including a pro rata part of all items of income, gain, loss and deduction taken into account in computing Net Income for such taxable period) shall be allocated as follows:

(i)    First, to the General Partner until the aggregate amount of Net Income allocated to the General Partner pursuant to this Section 6.1(a)(i) for the current and all previous taxable periods is equal to the aggregate amount of Net Loss allocated to the General Partner pursuant to Section 6.1(b)(v) for all previous taxable periods;

(ii)    Second, 100% to the General Partner and the Unitholders, in accordance with their respective Percentage Interests, until the aggregate Net Income allocated to such Partners pursuant to this Section 6.1(a)(ii) for the current and all previous taxable periods is equal to the aggregate Net Losses allocated to such Partners pursuant to Section 6.1(b)(ii) and (iii) for all previous taxable periods; and

(iii)    Third, the balance, if any, 100% to the General Partner and the Unitholders, in accordance with their respective Percentage Interests.

(b)     Net Loss . Net Loss for each taxable period (including a pro rata part of each item of income, gain, loss and deduction taken into account in computing Net Loss for such taxable period) shall be allocated as follows:

(i)    First, 100% to the General Partner and the Unitholders, in accordance with their respective Percentage Interests, until the aggregate Net Losses allocated pursuant to this Section 6.1(b)(i) for the current and all previous taxable periods is equal to the aggregate Net Income allocated to such Partners pursuant to Section 6.1(a)(iii) for all previous taxable periods, provided that the Net Losses shall not be allocated pursuant to this Section 6.1(b)(i) to the extent that such allocation would cause any Unitholder to have a deficit balance in its Adjusted Capital Account at the end of such taxable period (or increase any existing deficit balance in its Adjusted Capital Account);

(ii)    Second, 100% to the General Partner and the Unitholders, in accordance with their respective Percentage Interests; provided that Net Losses shall not be allocated pursuant to this Section 6.1(b)(ii) to the extent that such allocation would cause any Unitholder to have a deficit balance in its Adjusted Capital Account at the end of such taxable period (or increase any existing deficit balance in its Adjusted Capital Account) as such Adjusted Capital Accounts would be determined without regard to any Series A Preferred Units then held by such Unitholders;

(iii)    Third, (x) to the General Partner in accordance with its Percentage Interest and (y) the balance to the Unitholders holding Units other than Series A Preferred Units in accordance with the positive balances in their Adjusted Capital Accounts as such Adjusted Capital Accounts would be determined without regard to any Series A Preferred Units then held by such Unitholders;

(iv)    Fourth, (x) to the General Partner in accordance with its Percentage Interests and (y) the balance to the Series A Preferred Unitholders in accordance with the positive balances in their Adjusted Capital Accounts; and

(v)    Fifth, the balance, if any, 100% to the General Partner.

(c)     Net Termination Gains and Losses . Net Termination Gain or Net Termination Loss occurring during a taxable period shall be allocated in the manner set forth in this Section 6.1(c). All allocations under this Section 6.1(c) shall be made after Capital Account balances have been adjusted by all other allocations provided under this Section 6.1 and after all distributions of Available Cash provided under Section 6.4 and Section 6.5 have been made; provided, however, that solely for purposes of this Section 6.1(c), Capital Accounts shall not be adjusted for distributions made pursuant to Section 12.4; provided, further , that Net Termination Gain or Net Termination Loss attributable to (i) Liquidation Gain or Liquidation Loss shall be allocated on the last day of the taxable period during which such Liquidation Gain or Liquidation Loss occurred, (ii) Sale Gain or Sale Loss shall be allocated as of the time of the sale or disposition giving rise to such Sale Gain or Sale Loss and allocated to the Partners consistent with the second proviso set forth in Section 6.2(e) and (iii) Revaluation Gain or Revaluation Loss shall be allocated on the date of the Revaluation Event giving rise to such Revaluation Gain or Revaluation Loss.

(i)    Subject to the provisions set forth in the last sentence of this Section 6.1(c)(i), Net Termination Gain (including a pro rata part of each item of income, gain, loss, and deduction taken into account in computing Net Termination Gain) shall be allocated in the following order and priority:

(A)    First, to each Partner having a deficit balance in its Adjusted Capital Account, in the proportion that such deficit balance bears to the total deficit balances in the Adjusted Capital Accounts of all Partners, until each such Partner has been allocated Net Termination Gain equal to any such deficit balance in its Adjusted Capital Account;

(B)    Second, (x) to the General Partner in accordance with its Percentage Interest and (y) the Series A Preferred Unitholders, Pro Rata, until the Capital Account in respect of each Series A Preferred Unit is equal to the Series A Liquidation Value;

(D)    Fourth, (x) to the extent the Adjusted Capital Account of a Common Unit or comparable fraction thereof and Class C Unit (or converted Class C Unit) or comparable fraction thereof are not identical, (1) to all Unitholders holding such class of Units with the lowest Adjusted Capital Account, proportionately, a percentage equal to 100% less the percentage applicable to subclause (2) of this subclause (x) of this Clause (D) and (2) to the General Partner in accordance with its Percentage Interest, until the Adjusted Capital Account of such Unitholders (on a per Unit basis) is equal to the Adjusted Capital Account of the Unitholders holding the class of Units with the next lowest Adjusted Capital Account (on a per Unit basis), and (y) if after application of subclause (x) of this Clause (D), the Adjusted Capital Account of a Common Unit or comparable fraction thereof and a Class C Unit or comparable fraction thereof, on the one hand, and a Class B Unit (or converted Class B Unit) or comparable fraction thereof, on the other hand, are not identical, (1) to all Unitholders holding the class (or classes) of Units with the lower Adjusted Capital Account, proportionately, a percentage equal to 100% less the percentage applicable to subclause (2) of this subclause (y) of this Clause (D) and (2) to the General Partner in accordance with its Percentage Interest, until the Adjusted Capital Accounts of all of such Unitholders in such Units (on a per Unit basis) are equal;

(E)    Fifth, 100% to the General Partner and all Unitholders in accordance with their respective Percentage Interests, until the Capital Account in respect of each Common Unit then Outstanding is equal to the sum of (1) its Unrecovered Initial Unit Price, (2) the Unpaid MQD, and (3) the excess of (aa) the First Target Distribution less the Minimum Quarterly Distribution for each Quarter of the Partnership’s existence over (bb) the cumulative per Unit amount of any distributions of Available Cash that is deemed to be Operating Surplus made pursuant to Section 6.4(b) (the sum of (1), (2), (3) and (4) is hereinafter defined as the “ First Liquidation Target Amount ”);

(F)    Sixth, (x) to the General Partner in accordance with its Percentage Interest, (y) 13% to the holders of the Incentive Distribution Rights, Pro Rata, and (z) to all Unitholders other than Series A Preferred Unitholders, Pro Rata, a percentage equal to 100% less the sum of the percentages applicable to subclauses (x) and (y) of this clause (F), until the Capital Account in respect of each Common Unit then Outstanding is equal to the sum of (1) the First Liquidation Target Amount, and (2) the excess of (aa) the Second Target Distribution less the First Target Distribution for each Quarter of the Partnership’s existence over (bb) the cumulative per Unit amount of any distributions of Available Cash that is deemed to be Operating Surplus made pursuant to Section 6.4(c) (the sum of (1) and (2) is hereinafter defined as the “ Second Liquidation Target Amount ”);

(H)    Finally, (x) to the General Partner in accordance with its Percentage Interest, (y) 48% to the holders of the Incentive Distribution Rights, Pro Rata, and (z) to all Unitholders other than Series A Preferred Unitholders, Pro Rata, a percentage equal to 100% less the sum of the percentages applicable to subclauses (x) and (y) of this clause (H).

Notwithstanding the foregoing provisions in this Section 6.1(c)(i), the General Partner may adjust the amount of any Net Termination Gain arising in connection with a Revaluation Event that is allocated to the holders of Incentive Distribution Rights in a manner that will result (1) in the Capital Account for each Common Unit that is Outstanding prior to such Revaluation Event being equal to the Event Issue Value and (2) to the greatest extent possible, the Capital Account with respect to the Incentive Distribution Rights that are Outstanding prior to such Revaluation Event being equal to the amount of Net Termination Gain that would be allocated to the holders of the Incentive Distribution Rights pursuant to this Section 6.1(c)(i) if (i) the Capital Accounts with respect to all Partnership Interests that were Outstanding immediately prior to such Revaluation Event were equal to zero and (ii) the aggregate Carrying Value of all Partnership property equaled the aggregate amount of all of the Partnership’s Liabilities.

(ii)    Net Termination Loss (including a pro rata part of each item of income, gain, loss, and deduction taken into account in computing Net Termination Loss) shall be allocated:

(A)    First, (x) if the Adjusted Capital Account of a Common Unit or comparable fraction thereof and a Class C Unit (or converted Class C Unit) or

comparable fraction thereof and a Class B Unit (or converted Class B Unit) or comparable fraction thereof are not identical, (1) to the Unitholders holding the class of Units with the highest Adjusted Capital Account, proportionately, a percentage equal to 100% less the percentage applicable to subclause (2) of this subclause (x) of this Clause (A) and (2) to the General Partner, in accordance with its Percentage Interest, until the Adjusted Capital Account of such Unitholders (on a per Unit basis) is equal to the Adjusted Capital Account of the Unitholders holding the class of Units with the next highest Adjusted Capital Account (on a per Unit basis), and (y) if after application of subclause (x) of this Clause (A), the Adjusted Capital Account of a Common Unit or comparable fraction thereof and a Class C Unit (or converted Class C Unit) or comparable fraction thereof, on the one hand, and a Class B Unit (or converted Class B Unit) or comparable fraction thereof, on the other hand, are not identical, (1) to the Unitholders holding the class(es) of Units with the higher Adjusted Capital Account, proportionately, a percentage equal to 100% less the percentage applicable to subclause (2) of this subclause (y) of this Clause (A), and (2) to the General Partner, in accordance with its Percentage Interest, until the Adjusted Capital Account of each Common Unit or comparable fraction thereof, each Class C Unit (or converted Class C Unit) or comparable fraction thereof and each Class B Unit (or converted Class B Unit) or comparable fraction thereof are equal;

(B)    Second, (x) to the General Partner in accordance with its Percentage Interest and (y) to all Unitholders other than Series A Preferred Unitholders, Pro Rata, a percentage equal to 100% less the percentage applicable to subclause (x) of this clause (B) until the Capital Account in respect of each Unit then Outstanding has been reduced to zero;

(C)    Third, (x) to the General Partner in accordance with its Percentage Interest and (y) to the Series A Preferred Unitholders, Pro Rata, a percentage equal to 100% less the percentage applicable to subclause (x) of this clause (C) until the Capital Account in respect of each Series A Preferred Unit then Outstanding has been reduced to zero; and

(D)    Fourth, the balance, if any, 100% to the General Partner.

(d)     Special Allocations . Notwithstanding any other provision of this Section 6.1, the following special allocations shall be made for each taxable period:

(i)     Partnership Minimum Gain Chargeback . Notwithstanding any other provision of this Section 6.1, if there is a net decrease in Partnership Minimum Gain during any Partnership taxable period, each Partner shall be allocated items of Partnership income and gain for such period (and, if necessary, subsequent periods) in the manner and amounts provided in Treasury Regulation Sections 1.704-2(f)(6), 1.704-2(g)(2) and 1.704-2(j)(2)(i), or any successor provision. For purposes of this Section 6.1(d), each Partner’s Adjusted Capital Account balance shall be determined, and the allocation of gross income or gain required hereunder shall be effected, prior to the application of any other allocations pursuant

to this Section 6.1(d) with respect to such taxable period (other than an allocation pursuant to Section 6.1(d)(vi) and Section 6.1(d)(vii)). This Section 6.1(d)(i) is intended to comply with the Partnership Minimum Gain chargeback requirement in Treasury Regulation Section 1.704-2(f) and shall be interpreted consistently therewith.

(ii)     Chargeback of Partner Nonrecourse Debt Minimum Gain . Notwithstanding the other provisions of this Section 6.1 (other than Section 6.1(d)(i)), except as provided in Treasury Regulation Section 1.704-2(i)(4), if there is a net decrease in Partner Nonrecourse Debt Minimum Gain during any Partnership taxable period, any Partner with a share of Partner Nonrecourse Debt Minimum Gain at the beginning of such taxable period shall be allocated items of Partnership income and gain for such period (and, if necessary, subsequent periods) in the manner and amounts provided in Treasury Regulation Sections 1.704-2(i)(4) and 1.704-2(j)(2)(ii), or any successor provisions. For purposes of this Section 6.1(d), each Partner’s Adjusted Capital Account balance shall be determined, and the allocation of gross income or gain required hereunder shall be effected, prior to the application of any other allocations pursuant to this Section 6.1(d), other than Section 6.1(d)(i) and other than an allocation pursuant to Section 6.1(d)(vi) and Section 6.1(d)(vii), with respect to such taxable period. This Section 6.1(d)(ii) is intended to comply with the chargeback of items of income and gain requirement in Treasury Regulation Section 1.704-2(i)(4) and shall be interpreted consistently therewith.

(iii)     Priority Allocations .

(A)    If the amount of cash or the Net Agreed Value of any property distributed (except cash or property distributed pursuant to Section 12.4 or with respect to Series A Preferred Units) with respect to a Unit for a taxable period exceeds the amount of cash or the Net Agreed Value of property distributed with respect to another Unit for the same taxable period (the amount of the excess, an “ Excess Distribution ” and the Unit with respect to which the greater distribution is paid, an “ Excess Distribution Unit ”), then (1) there shall be allocated gross income and gain to each Unitholder receiving an Excess Distribution with respect to the Excess Distribution Unit until the aggregate amount of such items allocated with respect to such Excess Distribution Unit pursuant to this Section 6.1(d)(iii)(A) for the current taxable period and all previous taxable periods is equal to the amount of the Excess Distribution; and (2) the General Partner shall be allocated gross income and gain with respect to each such Excess Distribution in an amount equal to the product obtained by multiplying (aa) the quotient determined by dividing (x) the General Partner’s Percentage Interest at the time when the Excess Distribution occurs by (y) a percentage equal to 100% less the General Partner’s Percentage Interest at the time when the Excess Distribution occurs, times (bb) the total amount allocated in clause (1) above with respect to such Excess Distribution.

(B)    After the application of Section 6.1(d)(iii)(A), all or any portion of the remaining items of Partnership gross income or gain for the taxable period, if any, shall be allocated (1) to the holders of Incentive Distribution Rights, Pro Rata,

until the aggregate amount of such items allocated to the holders of Incentive Distribution Rights pursuant to this Section 6.1(d)(iii)(B) for the current taxable period and all previous taxable periods is equal to the cumulative amount of all Incentive Distributions made to the holders of Incentive Distribution Rights from the Closing Date to a date 45 days after the end of the current taxable period; and (2) to the General Partner an amount equal to the product of (aa) an amount equal to the quotient determined by dividing (x) the General Partner’s Percentage Interest by (y) the sum of 100% less the General Partner’s Percentage Interest times (bb) the sum of the amounts allocated in clause (1) above.

(iv)     Qualified Income Offset . In the event any Partner unexpectedly receives any adjustments, allocations or distributions described in Treasury 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 Partnership gross income and gain shall be specially allocated to such Partner in an amount and manner sufficient to eliminate, to the extent required by the Treasury Regulations promulgated under Section 704(b) of the Code, the deficit balance, if any, in its Adjusted Capital Account created by such adjustments, allocations or distributions as quickly as possible; provided that an allocation pursuant to this Section 6.1(d)(iv) shall be made only if and to the extent that such Partner would have a deficit balance in its Adjusted Capital Account after all other allocations provided for in this Section 6.1 have been tentatively made as if this Section 6.1(d)(iv) were not in this Agreement.

(v)     Gross Income Allocations . In the event any Partner has a deficit balance in its Capital Account at the end of any Partnership taxable period in excess of the sum of (A) the amount such Partner is required to restore pursuant to the provisions of this Agreement and (B) the amount such Partner is deemed obligated to restore pursuant to Treasury Regulation Sections 1.704-2(g) and 1.704-2(i)(5), such Partner shall be specially allocated items of Partnership gross income and gain in the amount of such excess as quickly as possible; provided that an allocation pursuant to this Section 6.1(d)(v) shall be made only if and to the extent that such Partner would have a deficit balance in its Adjusted Capital Account after all other allocations provided for in this Section 6.1 have been tentatively made as if Section 6.1(d)(iv) and this Section 6.1(d)(v) were not in this Agreement.

(vi)     Nonrecourse Deductions . Nonrecourse Deductions for any taxable period shall be allocated to the Partners Pro Rata. If the General Partner determines that the Partnership’s Nonrecourse Deductions should be allocated in a different ratio to satisfy the safe harbor requirements of the Treasury Regulations promulgated under Section 704(b) of the Code, the General Partner is authorized, upon notice to the other Partners, to revise the prescribed ratio to the numerically closest ratio that does satisfy such requirements.

(vii)     Partner Nonrecourse Deductions . Partner Nonrecourse Deductions for any taxable period shall be allocated 100% to the Partner that bears the Economic Risk of Loss with respect to the Partner Nonrecourse Debt to which such Partner Nonrecourse Deductions are attributable in accordance with Treasury Regulation Section 1.704-2(i). If more than one Partner bears the Economic Risk of Loss with respect to a Partner Nonrecourse Debt, such

Partner Nonrecourse Deductions attributable thereto shall be allocated between or among such Partners in accordance with the ratios in which they share such Economic Risk of Loss.

(viii)     Nonrecourse Liabilities . For purposes of Treasury Regulation Section 1.752-3(a)(3), the Partners agree that Nonrecourse Liabilities of the Partnership in excess of the sum of (A) the amount of Partnership Minimum Gain and (B) the total amount of Nonrecourse Built-in Gain shall be allocated among the Partners in accordance with their respective Percentage Interests.

(ix)     Certain Distributions Subject to Section 734(b).     To the extent an adjustment to the adjusted tax basis of any Partnership asset pursuant to Section 734(b) of the Code (including pursuant to Treasury Regulation Section 1.734-2(b)(1)) is required, pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts as a result of a distribution to a Partner in complete liquidation of such Partner’s interest in the Partnership, the amount of such adjustment to the Capital Accounts shall be treated as an item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment decreases such basis) taken into account pursuant to Section 5.5, and such item of gain or loss shall be specially allocated to the Partners in a manner consistent with the manner in which their Capital Accounts are required to be adjusted pursuant to such Section of the Treasury Regulations.

(x)     Economic Uniformity .

(A)    At the election of the General Partner with respect to any taxable period ending upon, or after, the conversion of the Class B Units pursuant to Section 5.11(f), all or a portion of the remaining items of Partnership gross income or gain for such taxable period, after taking into account allocations pursuant to Section 6.1(d)(iii), shall be allocated 100% to the holder or holders of the Common Units resulting from the conversion pursuant to Section 5.11(f) (“ Converted Common Units ”) in the proportion of the number of the Converted Common Units held by such holder or holders to the total number of Converted Common Units then Outstanding, until each such holder has been allocated an amount of income or gain that increases the Capital Account maintained with respect to such Converted Common Units to an amount equal to the product of (A) the number of Converted Common Units held by such holder and (B) the Per Unit Capital Amount for a Common Unit (other than a Common Unit issued upon the conversion of a Series A Preferred Unit, a Class B Unit or a Class C Unit). The purpose of this allocation is to establish uniformity between the Capital Accounts underlying Converted Common Units and the Capital Accounts underlying most or all of the Common Units held by Persons other than the General Partner and its Affiliates immediately prior to the receipt of Common Units pursuant to Section 5.11(f).

(B)    At the election of the General Partner with respect to any taxable period ending upon, or after, the conversion of the Class C Units into Common Units pursuant to Section 5.12(c), all or a portion of the remaining items of Partnership gross income, gain, deduction or loss for such taxable period, after taking into account

allocations pursuant to Section 6.1(d)(iii), shall be allocated 100% to the holder or holders of the Common Units resulting from the conversion of Class C Units pursuant to Section 5.12(c) (“ Converted Class C Units ”) in the proportion of the number of the Converted Class C Units held by such holder or holders to the total number of Converted Class C Units then Outstanding, until each such holder has been allocated an amount of income, gain, loss or deduction that causes the Capital Account maintained with respect to such Converted Class C Units to an amount equal to the product of (A) the number of Converted Class C Units held by such holder and (B) the Per Unit Capital Amount for a Common Unit (other than a Common Unit issued upon the conversion of a Series A Preferred Unit, a Class B Unit or a Class C Unit). The purpose of this allocation is to establish uniformity between the Capital Accounts underlying Converted Class C Units and the Capital Accounts underlying most or all of the Common Units held by Persons other than the General Partner and its Affiliates immediately prior to the conversion of Class C Units into Common Units. The General Partner shall have discretion as to the priority of the application of this Section 6.1(d)(x)(B) as compared to Sections 6.1(d)(x)(A).

(C)    Prior to making any allocations pursuant to Section 6.1(d)(xv)(C), if a Revaluation Event occurs, then after the application of Section 6.1(d)(x)(A)-(B), any remaining Unrealized Gains and Unrealized Losses shall be allocated to the holders of (A) Outstanding Privately Placed Units, Pro Rata, or (B) Outstanding Common Units (other than Privately Placed Units), Pro Rata, as applicable, in a manner that to the nearest extent possible results in the Capital Accounts maintained with respect to each Privately Placed Unit equaling the Per Unit Capital Amount for an Initial Common Unit.

(D)    For the proper administration of the Partnership and for the preservation of uniformity of the Limited Partner Interests (or any class or classes thereof), the General Partner shall (1) adopt such conventions as it deems appropriate in determining the amount of depreciation, amortization and cost recovery deductions; (2) make special allocations of income, gain, loss, deduction, Unrealized Gain or Unrealized Loss; and (3) amend the provisions of this Agreement as appropriate (x) to reflect the proposal or promulgation of Treasury Regulations under Section 704(b) or Section 704(c) of the Code or (y) otherwise to preserve or achieve uniformity of the Limited Partner Interests (or any class or classes thereof) that are publicly traded as a single class. The General Partner may adopt such conventions, make such allocations and make such amendments to this Agreement as provided in this Section 6.1(d)(x)(D) only if such conventions, allocations or amendments would not have a material adverse effect on the Partners, the holders of any class or classes of Outstanding Limited Partner Interests or the Partnership.

(xi)     Allocations with respect to Series A Preferred Units.

(A)    Items of Partnership gross income shall be allocated (x) to the General Partner in accordance with its Percentage Interest and (y) to the Series A Preferred

Unitholders, Pro Rata, until the aggregate amount of gross income allocated to each Series A Preferred Unitholder pursuant hereto for the current taxable period and all previous taxable periods is equal to the cumulative amount of all cash distributions made with respect to such Series A Preferred Unit pursuant to Section 5.13(b)(i) from the date such Series A Preferred Unit was issued to a date 45 days after the end of the current taxable period.

(B)    Items of Partnership gross income shall be allocated (x) to the General Partner in accordance with its Percentage Interest and (y) to the Series A Preferred Unitholders, Pro Rata, until the aggregate amount of gross income allocated to each Series A Preferred Unitholder pursuant hereto for the current taxable period and all previous taxable periods is equal to the cumulative amount of all Net Losses allocated to such Series A Preferred Unitholder pursuant to Section 6.1(b)(iv) for all previous taxable periods.

(C)    Notwithstanding any other provision of this Section 6.1 (other than the Required Allocations), if (A) the Liquidation Date occurs prior to the conversion of the last Outstanding Series A Preferred Unit and (B) after having made all other allocations provided for in this Section 6.1 for the taxable period in which the Liquidation Date occurs, the Per Unit Capital Amount of each Series A Preferred Unit does not equal or exceed the Series A Liquidation Value, then items of gross income, gain, loss and deduction for such taxable period shall be allocated among the Partners in a manner determined appropriate by the General Partner so as to cause, to the maximum extent possible, the Per Unit Capital Amount in respect of each Series A Preferred Unit to equal the Series A Liquidation Value (and no other allocation pursuant to this Agreement shall reverse the effect of such allocation). For the avoidance of doubt, the reallocation of items set forth in the immediately preceding sentence provides that, to the extent necessary to achieve the Per Unit Capital Amount balances described above, items of gross income and gain that would otherwise be included in Net Income or Net Loss, as the case may be, for the taxable period in which the Liquidation Date occurs, shall be reallocated from the Unitholders holding Units other than Series A Preferred Units to Unitholders holding Series A Preferred Units. In the event that (i) the Liquidation Date occurs on or before the date (not including any extension of time) prescribed by law for the filing of the Partnership’s federal income tax return for the taxable period immediately prior to the taxable period in which the Liquidation Date occurs and (ii) the reallocation of items for the taxable period in which the Liquidation Date occurs as set forth above in this Section 6.1(d)(xi)(C) fails to achieve the Per Unit Capital Amounts described above, items of gross income, gain, loss and deduction that would otherwise be included in the Net Income or Net Loss, as the case may be, for such prior taxable period shall be reallocated among all Partners in a manner that will, to the maximum extent possible and after taking into account all other allocations made pursuant to this Section 6.1(d)(xi)(C), cause the Per Unit Capital Amount in respect of each Series A Preferred Unit to equal the Series A Liquidation Value.

(xii)     Curative Allocation .

(A)    Notwithstanding any other provision of this Section 6.1, other than the Required Allocations, the General Partner shall take the Required Allocations into account in making the Agreed Allocations so that, to the extent possible, the net amount of items of gross income, gain, loss and deduction allocated to each Partner pursuant to the Required Allocations and the Agreed Allocations, together, shall be equal to the net amount of such items that would have been allocated to each such Partner under the Agreed Allocations had the Required Allocations and the related Curative Allocation not otherwise been provided in this Section 6.1. In exercising its discretion under this Section 6.1(d)(xii)(A), the General Partner may take into account future Required Allocations that, although not yet made, are likely to offset other Required Allocations previously made. Allocations pursuant to this Section 6.1(d)(xii)(A) shall only be made with respect to Required Allocations to the extent the General Partner determines that such allocations will otherwise be inconsistent with the economic agreement among the Partners.

(B)    The General Partner shall, with respect to each taxable period, (1) apply the provisions of Section 6.1(d)(xii)(A) in whatever order is most likely to minimize the economic distortions that might otherwise result from the Required Allocations, and (2) divide all allocations pursuant to Section 6.1(d)(xii)(A) among the Partners in a manner that is likely to minimize such economic distortions.

(xiii)     Exercise of Noncompensatory Options . In accordance with Treasury Regulation Section 1.704-1(b)(2)(iv)(s) and as provided in Section 5.5(d)(i), immediately after the conversion of a Limited Partnership Interest into Common Units (each such Common Unit a “ Conversion Unit ”) upon the exercise of a Noncompensatory Option, the Capital Account of each Partner and the Carrying Value of each Partnership property shall be adjusted to reflect its fair market value immediately after such conversion and any resulting Unrealized Gain (if the Capital Account of each such Conversion Unit is less than the Per Unit Capital Account for a then Outstanding Initial Common Unit) or Unrealized Loss (if the Capital Account of each such Conversion Unit is greater than the Per Unit Capital Account for a then Outstanding Initial Common Unit) will be allocated (x) to the General Partner in accordance with its Percentage Interest and (y) to each Partner holding Conversion Units, Pro Rata, until the Capital Account of each such Conversion Unit is equal to the Per Unit Capital Amount for a then Outstanding Initial Common Unit. Any remaining Unrealized Gain or Unrealized Loss will be allocated to the Partners pursuant to Section 6.1(c) and Section 6.1(d).  In determining such Unrealized Gain or Unrealized Loss, the aggregate cash amount and fair market value of all Partnership assets (including, without limitation, cash or cash equivalents) immediately after the conversion of a Limited Partner Interest shall be determined by the General Partner using such reasonable method of valuation as it may adopt;  provided , however , that the General Partner, in arriving at such valuation, must take fully into account the fair market value of the Partnership Interests of all Partners at such time and must make such adjustments to such valuation as required by Treasury Regulation Section 1.704-1(b)(2)(iv)(h)(2).  The General Partner shall allocate

such aggregate value among the assets of the Partnership in such manner as it determines in its discretion to be reasonable.  If, after making the allocations of Unrealized Gain and Unrealized Loss as set forth above in this Section 6.1(d)(xiii), the Capital Account of each Partner with respect to each Conversion Unit received upon such conversion of the Limited Partner Interest is less than the Per Unit Capital Amount for a then Outstanding Initial Common Unit, then, in accordance with Treasury Regulation Section 1.704-1(b)(2)(iv)(s)(3), Capital Account balances shall be reallocated between the Partners holding Common Units (other than Conversion Units) and Partners holding Conversion Units so as to cause the Capital Account of each Partner holding a Conversion Unit to equal, on a per Unit basis with respect to each such Conversion Unit, the Per Unit Capital Amount for a then Outstanding Initial Common Unit.

(xiv)     Revaluation Gain or Loss – Class C Units . If a Revaluation Event occurs after the initial issuance of Class C Units, any resulting Revaluation Gain or Revaluation Loss shall be allocated in a manner that, to the nearest extent possible, results in the Capital Accounts maintained with respect to the Class C Units and the Converted Class C Units on a per unit basis equaling the Per Unit Capital Amount for a Common Unit (other than a Common Unit issued upon the conversion of a Series A Preferred Unit, a Class B Unit or a Class C Unit). Any remaining Revaluation Gain shall be allocated to the Partners pursuant to Section 6.1(c).

(xv)     Corrective and Other Allocations . In the event of any allocation of Additional Book Basis Derivative Items or a Net Termination Loss, the following rules shall apply:

(A)    The General Partner shall allocate Additional Book Basis Derivative Items consisting of depreciation, amortization, depletion or any other form of cost recovery (other than Additional Book Basis Derivative Items included in Net Termination Gain or Net Termination Loss) with respect to any Adjusted Property to the Unitholders, Pro Rata, the holders of Incentive Distribution Rights, and the General Partner in the same proportion as the Net Termination Gain or Net Termination Loss resulting from the Revaluation Event that gave rise to such Additional Book Basis Derivative Items was allocated to them pursuant to Section 6.1(c).

(B)    If a sale or other taxable disposition of an Adjusted Property, including, for this purpose, inventory (“ Disposed of Adjusted Property ”) occurs other than in connection with an event giving rise to Sale Gain or Sale Loss, the General Partner shall allocate (1) items of gross income and gain (x) away from the holders of Incentive Distribution Rights and the General Partner and (y) to the Unitholders, or (2) items of deduction and loss (x) away from the Unitholders and (y) to the holders of Incentive Distribution Rights and the General Partner, to the extent that the Additional Book Basis Derivative Items with respect to the Disposed of Adjusted Property (determined in accordance with the last sentence of the definition of Additional Book Basis Derivative Items) treated as having been allocated to the Unitholders pursuant to this Section 6.1(d)(xv)(B) exceed their Share of Additional

Book Basis Derivative Items with respect to such Disposed of Adjusted Property. For purposes of this Section 6.1(d)(xv)(B), the Unitholders shall be treated as having been allocated Additional Book Basis Derivative Items to the extent that such Additional Book Basis Derivative Items have reduced the amount of income that would otherwise have been allocated to the Unitholders under the Partnership Agreement (e.g., Additional Book Basis Derivative Items taken into account in computing cost of goods sold would reduce the amount of book income otherwise available for allocation among the Partners). Any allocation made pursuant to this Section 6.1(d)(xv)(B) shall be made after all of the other Agreed Allocations have been made as if this Section 6.1(d)(xv) were not in this Agreement and, to the extent necessary, shall require the reallocation of items that have been allocated pursuant to such other Agreed Allocations.

(C)    Net Termination Loss in an amount equal to the lesser of (1) such Net Termination Loss and (2) the Aggregate Remaining Net Positive Adjustments shall be allocated in such manner as is determined by the General Partner that, to the extent possible, the Capital Account balances of the Partners will equal the amount they would have been had no prior Book-Up Events occurred, and any remaining Net Termination Loss shall be allocated pursuant to Section 6.1(c) hereof. In allocating Net Termination Loss pursuant to this Section 6.1(d)(xv)(C), the General Partner shall attempt, to the extent possible, to cause the Capital Accounts of the Unitholders, on the one hand, and holders of the Incentive Distribution Rights, on the other hand, to equal the amount they would equal if (i) the Carrying Values of the Partnership’s property had not been previously adjusted in connection with any prior Book-Up Events, (ii) Unrealized Gain and Unrealized Loss (or, in the case of a liquidation, Liquidation Gain or Liquidation Loss) with respect to such Partnership Property were determined with respect to such unadjusted Carrying Values, and (iii) any resulting Net Termination Gain had been allocated pursuant to Section 6.1(c)(i) (including, for the avoidance of doubt, taking into account the provisions set forth in the last sentence of Section 6.1(c)(i)).

(D)    In making the allocations required under this Section 6.1(d)(xv), the General Partner may apply whatever conventions or other methodology it determines will satisfy the purpose of this Section 6.1(d)(xv). Without limiting the foregoing, if an Adjusted Property is contributed by the Partnership to another entity classified as a partnership for U.S. federal income tax purposes (the “ lower tier partnership ”), the General Partner may make allocations similar to those described in Sections 6.1(d)(xv)(A), (B), and (C) to the extent the General Partner determines such allocations are necessary to account for the Partnership’s allocable share of income, gain, loss and deduction of the lower tier partnership that relate to the contributed Adjusted Property in a manner that is consistent with the purpose of this Section 6.1(d)(xv)).

(xvi)     Allocations Regarding Certain Payments Made to or on Behalf of Employees and Other Service Providers. Consistent with the principles of Treasury Regulation Section 1.83-6(d), if any Partner (or its successor) transfers property (including cash) to or on behalf

of any employee or other service provider of the Partnership Group and such Partner is not entitled to be reimbursed by (or otherwise elects not to seek reimbursement from) the Partnership for the value of such property, then any items of deduction or loss resulting from or attributable to such transfer shall be allocated to the Partner (or its successor) that made such transfer and such Partner shall be deemed to have contributed such property to the Partnership pursuant to Section 5.14.

Section 6.2     Allocations for Tax Purposes .

(a)    Except as otherwise provided herein, for federal income tax purposes, 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 Section 6.1.

(b)    In an attempt to eliminate Book-Tax Disparities attributable to a Contributed Property or Adjusted Property, items of income, gain, loss, depreciation, amortization and cost recovery deductions shall be allocated for federal income tax purposes among the Partners in the manner provided under Section 704(c) of the Code, and the Treasury Regulations promulgated under Section 704(b) and 704(c) of the Code, as determined appropriate by the General Partner (taking into account the General Partner’s discretion under Section 6.1(d)(x)(D)); provided that in all events the General Partner shall apply the “remedial allocation method” in accordance with the principles of Treasury Regulation Section 1.704-3(d).

(c)    The General Partner may determine to depreciate or amortize the portion of an adjustment under Section 743(b) of the Code attributable to unrealized appreciation in any Adjusted Property (to the extent of the unamortized Book-Tax Disparity) using a predetermined rate derived from the depreciation or amortization method and useful life applied to the unamortized Book-Tax Disparity of such property, despite any inconsistency of such approach with Treasury Regulation Section 1.167(c)-l(a)(6) or any successor regulations thereto. If the General Partner determines that such reporting position cannot reasonably be taken, the General Partner may adopt depreciation and amortization conventions under which all purchasers acquiring Limited Partner Interests in the same month would receive depreciation and amortization deductions, based upon the same applicable rate as if they had purchased a direct interest in the Partnership’s property. If the General Partner chooses not to utilize such aggregate method, the General Partner may use any other depreciation and amortization conventions to preserve the uniformity of the intrinsic tax characteristics of any Limited Partner Interests, so long as such conventions would not have a material adverse effect on the Limited Partners or the Record Holders of any class or classes of Limited Partner Interests.

(d)    In accordance with Treasury Regulation Sections 1.1245-1(e) and 1.1250-1(f), any gain allocated to the Partners upon the sale or other taxable disposition of any Partnership asset shall, to the extent possible, after taking into account other required allocations of gain pursuant to this Section 6.2, be characterized as Recapture Income in the same proportions and to the same extent as such Partners (or their predecessors in interest) have been allocated any deductions directly or indirectly giving rise to the treatment of such gains as Recapture Income.

(e)    All items of income, gain, loss, deduction and credit recognized by the Partnership for federal income tax purposes and allocated to the Partners in accordance with the provisions hereof shall be determined without regard to any election under Section 754 of the Code that may be made by the Partnership; provided, however , that such allocations, once made, shall be adjusted (in the manner determined by the General Partner) to take into account those adjustments permitted or required by Sections 734 and 743 of the Code.

(f)    Each item of Partnership income, gain, loss and deduction, for federal income tax purposes, shall be determined on an annual basis and prorated on a monthly basis and shall be allocated to the Partners as of the opening of the National Securities Exchange on which the Partnership Interests are listed or admitted to trading on the first Business Day of each month; provided, however , such items for the period beginning on the Closing Date and ending on the last day of the month in which the exercise in full of the Over-Allotment Option or the expiration of the Over-Allotment Option occurs shall be allocated to the Partners as of the opening of the National Securities Exchange on which the Partnership Interests are listed or admitted to trading on the first Business Day of the next succeeding month; and provided, further , that gain or loss on a sale or other disposition of any assets of the Partnership or any other extraordinary item of income or loss realized and recognized other than in the ordinary course of business, as determined by the General Partner, shall be allocated to the Partners as of the opening of the National Securities Exchange on which the Partnership Interests are listed or admitted to trading on the first Business Day of the month in which such gain or loss is recognized for federal income tax purposes. The General Partner may revise, alter or otherwise modify such methods of allocation to the extent permitted or required by Section 706 of the Code and the regulations or rulings promulgated thereunder.

(g)    Allocations that would otherwise be made to a Limited Partner under the provisions of this Article VI shall instead be made to the beneficial owner of Limited Partner Interests held by a nominee, agent or representative in any case in which such nominee, agent or representative has furnished the identity of such owner to the Partnership in accordance with Section 6031(c) of the Code or any other method determined by the General Partner.

(h)    If, as a result of an exercise of a Noncompensatory Option, a Capital Account reallocation is required under Treasury Regulation Section 1.704-1(b)(2)(iv)(s)(3), the General Partner shall make corrective allocations pursuant to Treasury Regulation Section 1.704-1(b)(4)(x).

Section 6.3     Requirement and Characterization of Distributions; Distributions to Record Holders .

(a)    Within 45 days following the end of each Quarter, an amount equal to 100% of Available Cash with respect to such Quarter shall, subject to Section 17-607 of the Delaware Act, be distributed in accordance with this Article VI, subject to Section 5.13(b)(i)(B), by the Partnership to the Partners as of the Record Date selected by the General Partner. All amounts of Available Cash distributed by the Partnership on any date from any source shall be deemed to be Operating Surplus until the sum of all amounts of Available Cash theretofore distributed by the Partnership to the Partners pursuant to Section 6.4 equals the Operating Surplus from the Closing Date through the close of the immediately preceding Quarter. Any remaining amounts of Available Cash distributed

by the Partnership on such date shall, except as otherwise provided in Section 6.5, be deemed to be “ Capital Surplus .” All distributions required to be made under this Agreement shall be made subject to Section 17-607 of the Delaware Act.

(b)    Notwithstanding Section 6.3(a), in the event of the dissolution and liquidation of the Partnership, all receipts received during or after the Quarter in which the Liquidation Date occurs shall be applied and distributed solely in accordance with, and subject to the terms and conditions of, Section 12.4.

(d)    Each distribution in respect of a Partnership Interest shall be paid by the Partnership, directly or through the Transfer Agent or through any other Person or agent, only to the Record Holder of such Partnership Interest as of the Record Date set for such distribution. Such payment shall constitute full payment and satisfaction of the Partnership’s liability in respect of such payment, regardless of any claim of any Person who may have an interest in such payment by reason of an assignment or otherwise.

Section 6.4     Distributions of Available Cash from Operating Surplus . Available Cash with respect to any Quarter that is deemed to be Operating Surplus pursuant to the provisions of Section 6.3 or Section 6.5, subject to Section 17-607 of the Delaware Act, shall be distributed as follows, except as otherwise required by Section 5.6(b) or Section 5.13(b)(i) in respect of additional Partnership Securities issued pursuant thereto:

(a)    First, (A) to the General Partner in accordance with its Percentage Interest; and (B) to the Unitholders other than holders of Class C Units, Pro Rata, a percentage equal to 100% less the General Partner’s Percentage Interest, until there has been distributed in respect of each Common Unit then Outstanding an amount equal to the Minimum Quarterly Distribution for such Quarter;

(b)    Second, (A) to the General Partner in accordance with its Percentage Interest; and (B) to the Unitholders other than holders of Class C Units, Pro Rata, a percentage equal to 100% less the General Partner’s Percentage Interest, until there has been distributed in respect of each Common Unit then Outstanding an amount equal to the excess of the First Target Distribution over the Minimum Quarterly Distribution for such Quarter;

(c)    Third, (A) to the General Partner in accordance with its Percentage Interest; (B) 13% to the holders of the Incentive Distribution Rights, Pro Rata; and (C) to all Unitholders other than holders of Class C Units, Pro Rata, a percentage equal to 100% less the sum of the percentages applicable to subclauses (A) and (B) of this clause (iii), until there has been distributed in respect of each Common Unit then Outstanding an amount equal to the excess of the Second Target Distribution over the First Target Distribution for such Quarter;

than holders of Class C Units, Pro Rata, a percentage equal to 100% less the sum of the percentages applicable to subclauses (A) and (B) of this clause (iv), until there has been distributed in respect of each Common Unit then Outstanding an amount equal to the excess of the Third Target Distribution over the Second Target Distribution for such Quarter; and

(e)    Thereafter, (A) to the General Partner in accordance with its Percentage Interest; (B) 48% to the holders of the Incentive Distribution Rights, Pro Rata; and (C) to all Unitholders other than holders of Class C Units, Pro Rata, a percentage equal to 100% less the sum of the percentages applicable to subclauses (A) and (B) of this clause (v);

provided , however , if the Minimum Quarterly Distribution, the First Target Distribution, the Second Target Distribution and the Third Target Distribution have been reduced to zero pursuant to the second sentence of Section 6.6(a), the distribution of Available Cash that is deemed to be Operating Surplus with respect to any Quarter will be made solely in accordance with Section 6.4(e).

Section 6.5     Distributions of Available Cash from Capital Surplus .

Available Cash that is deemed to be Capital Surplus pursuant to the provisions of Section 6.3(a) shall, subject to Section 17-607 of the Delaware Act, be distributed, unless the provisions of Section 6.3 require otherwise, (A) to the General Partner in accordance with its Percentage Interest and (B) to all Unitholders other than holders of Class C Units in accordance with their relative Adjusted Percentage Interests, a percentage equal to 100% less the General Partner’s Percentage Interest, until a hypothetical holder of a Common Unit acquired on the Closing Date has received with respect to such Common Unit, during the period since the Closing Date through such date, distributions of Available Cash that are deemed to be Capital Surplus in an aggregate amount equal to the Initial Unit Price. Available Cash that is deemed to be Capital Surplus shall then be distributed as if it were Operating Surplus and shall be distributed in accordance with Section 6.4.

Section 6.6     Adjustment of Minimum Quarterly Distribution and Target Distribution Levels .

In the event of a distribution of Available Cash that is deemed to be from Capital Surplus, the then applicable Minimum Quarterly Distribution, First Target Distribution, Second Target Distribution and Third Target Distribution, shall be adjusted proportionately downward to equal the product obtained by multiplying the otherwise applicable Minimum Quarterly Distribution, First Target Distribution, Second Target Distribution and Third Target Distribution, as the case may be, by a fraction of which the numerator is the Unrecovered Initial Unit Price of the Common Units immediately after giving effect to such distribution and of which the denominator is the Unrecovered Initial Unit Price of the Common Units immediately prior to giving effect to such distribution.

(b)    The Minimum Quarterly Distribution, First Target Distribution, Second Target Distribution and Third Target Distribution, shall also be subject to adjustment pursuant to Section 5.11 and Section 6.9.

Section 6.7     Special Provisions Relating to the Holders of Class B Units and Class C Units.

In connection with the condition imposed by this Section 6.7(b), the General Partner may take whatever steps are required to provide economic uniformity to such Common Units, including the application of Section 6.1(d)(x)(A); provided, however , that no such steps may be taken that would have a material adverse effect on the Unitholders holding Common Units represented by Common Unit Certificates (for this purpose the allocations of items of income, gain, loss or deduction with respect to Class B Units or with respect to Common Units will be deemed not to have a material adverse effect on the Common Units).

(c)    Except with respect to the right to vote on or approve matters requiring the vote or approval of a percentage of the holders of Outstanding Common Units and the right to participate in allocations of income, gain, loss and deduction and distributions made with respect to Common Units, the holder of a Class C Unit shall have all of the rights and obligations of a Unitholder holding Common Units hereunder; provided , however , that such Class C Units shall be and after conversion into Common Units pursuant to Section 5.12 shall remain subject to the provisions of Sections 5.5(c)(iii) and 6.1(d)(x)(B).

income tax characteristics, in all material respects, to the intrinsic economic and federal income tax characteristics of an Initial Common Unit. In connection with the condition imposed by this Section 6.7(d), the General Partner may take whatever steps are required to provide economic uniformity to such Common Units, including the application of Section 6.1(d)(x)(B); provided , however , that no such steps may be taken that would have a material adverse effect on the Unitholders holding Common Unit Certificates (for this purpose the allocations of items of income, gain, loss or deduction with respect to Class C Units or with respect to Common Units will be deemed not to have a material adverse effect on the Common Units).

Section 6.8     Special Provisions Relating to the Holders of Incentive Distribution Rights .

If legislation is enacted or the interpretation of existing language is modified by a governmental taxing authority so that a Group Member is treated as an association taxable as a corporation or is otherwise subject to an entity-level tax for federal, state or local income tax purposes, then the General Partner may reduce the Minimum Quarterly Distribution, the First Target Distribution, the Second Target Distribution and the Third Target Distribution to take into account the amount of income taxes that are payable by reason of any such new legislation or interpretation (the “ Incremental Income Taxes ”), or any portion thereof selected by the General Partner, in the manner provided in this Section 6.9. If the General Partner elects to reduce the Minimum Quarterly Distribution, the First Target Distribution, the Second Target Distribution and the Third Target Distribution for any Quarter with respect to all or a portion of any Incremental Income Taxes, the General Partner shall estimate for such Quarter the Partnership Group’s aggregate liability (the “ Estimated Incremental Quarterly Tax Amount ”) for all such income taxes that are payable by reason of any such new legislation or interpretation; provided that any difference between such estimate and the actual tax liability for such Quarter that is owed by reason of any such new legislation or interpretation shall be taken into account in determining the Estimated Incremental Quarterly Tax Amount with respect to each Quarter in which any such difference can be determined. For each such Quarter, the Minimum Quarterly Distribution, First Target Distribution, Second Target Distribution and Third Target Distribution, shall be the product obtained by multiplying (a) the amounts therefor that are set out herein prior to the application of this Section 6.9 times (b) the quotient obtained by dividing (i) Available Cash with respect to such Quarter by (ii) the sum of Available Cash with respect to such Quarter and the Estimated Incremental Quarterly Tax Amount for such Quarter, as determined by the General Partner.

Cash with respect to a Quarter will be deemed reduced by the Estimated Incremental Quarterly Tax Amount for that Quarter.

To the extent the General Partner determines such action to be necessary or appropriate, the General Partner shall file amendments to and restatements of the Certificate of Limited Partnership and do all things to maintain the Partnership as a limited partnership (or a partnership or other entity in which the limited partners have limited liability) under the laws of the State of Delaware or of any other state in which the Partnership may elect to do business or own property. Subject to the terms of Section 3.4(a), the General Partner shall not be required, before or after filing, to deliver or mail a copy of the Certificate of Limited Partnership, any qualification document or any amendment thereto to any Limited Partner.

Section 7.3     Restrictions on the General Partner’s Authority .

Except as provided in Article XII and Article XIV, the General Partner may not sell, exchange or otherwise dispose of all or substantially all of the assets of the Partnership Group, taken as a whole, in a single transaction or a series of related transactions (including by way of merger, consolidation, other combination or sale of ownership interests of the Partnership’s Subsidiaries) without the approval of holders of a Unit Majority; provided, however , that this provision shall not preclude or limit the General Partner’s ability to mortgage, pledge, hypothecate or grant a security interest in all or substantially all of the assets of the Partnership Group and shall not apply to any forced sale of any or all of the assets of the Partnership Group pursuant to the foreclosure of, or other realization upon, any such encumbrance. Without the approval of holders of a Unit Majority, the General Partner shall not, on behalf of the Partnership, except as permitted under Section 4.6, Section 11.1, Section 11.2 or Section 12.1(a), elect or cause the Partnership to elect a successor general partner of the Partnership.

Section 7.4     Reimbursement of the General Partner .

(a)    Except as provided in this Section 7.4 and elsewhere in this Agreement, the General Partner shall not be compensated for its services as a general partner or managing member of any Group Member.

(b)    The General Partner shall be reimbursed on a monthly basis, or such other basis as the General Partner may determine, for (i) all direct and indirect expenses it incurs or payments it makes on behalf of the Partnership Group (including salary, bonus, incentive compensation and other amounts paid to any Person, including Affiliates of the General Partner to perform services for the Partnership Group or for the General Partner in the discharge of its duties to the Partnership Group), and (ii) all other expenses allocable to the Partnership Group or otherwise incurred by the General Partner in connection with operating the Partnership Group’s business (including expenses allocated to the General Partner by its Affiliates). The General Partner shall determine the expenses that are allocable to the Partnership Group. Reimbursements pursuant to this Section 7.4 shall be in addition to any reimbursement to the General Partner as a result of indemnification pursuant to Section 7.7.

(c)    The General Partner, without the approval of the Limited Partners (who shall have no right to vote in respect thereof), may propose and adopt on behalf of the Partnership employee benefit plans, employee programs and employee practices (including plans, programs and practices involving the issuance of Partnership Securities or options to purchase or rights, warrants or appreciation rights or phantom or tracking interests relating to Partnership Securities), or cause the Partnership to issue Partnership Securities in connection with, or pursuant to, any employee benefit plan, employee program or employee practice maintained or sponsored by the General Partner, Group Member or any Affiliates in each case for the benefit of employees and directors of the General Partner or any of its Affiliates, in respect of services performed, directly or indirectly, for the benefit of the Partnership Group. The Partnership agrees to issue and sell to the General Partner or any of its Affiliates any Partnership Securities that the General Partner or such Affiliates are obligated to provide to any employees and directors pursuant to any such employee benefit plans, employee programs or employee practices. Expenses incurred by the General Partner in connection with any such plans, programs and practices (including the net cost to the General Partner or such

Affiliates of Partnership Securities purchased by the General Partner or such Affiliates from the Partnership to fulfill options or awards under such plans, programs and practices) shall be reimbursed in accordance with Section 7.4(b). Any and all obligations of the General Partner under any employee benefit plans, employee programs or employee practices adopted by the General Partner as permitted by this Section 7.4(c) shall constitute obligations of the General Partner hereunder and shall be assumed by any successor General Partner approved pursuant to Section 11.1 or Section 11.2 or the transferee of or successor to all of the General Partner’s General Partner Interest (represented by General Partner Units) pursuant to Section 4.6.

Section 7.5     Outside Activities .

(a)    After the Closing Date, the General Partner, for so long as it is the General Partner of the Partnership (i) agrees that its sole business will be to act as a general partner or managing member, as the case may be, of the Partnership and any other partnership or limited liability company of which the Partnership is, directly or indirectly, a partner or member and to undertake activities that are ancillary or related thereto (including being a limited partner in the Partnership) and (ii) shall not engage in any business or activity or incur any debts or liabilities except in connection with or incidental to (A) its performance as general partner or managing member, if any, of one or more Group Members or as described in or contemplated by the Registration Statement, (B) the acquiring, owning or disposing of debt or equity securities in any Group Member, or (C) the guarantee of, and mortgage, pledge, or encumbrance of any or all of its assets in connection with, any indebtedness of Anadarko, any of its successors or permitted assigns or any other Affiliate of the General Partner.

(b)    Except as set forth in the Omnibus Agreement, each Indemnitee (other than the General Partner) shall have the right to engage in businesses of every type and description and other activities for profit and to engage in and possess an interest in other business ventures of any and every type or description, whether in businesses engaged in or anticipated to be engaged in by any Group Member, independently or with others, including business interests and activities in direct competition with the business and activities of any Group Member, and none of the same shall constitute a breach of this Agreement or any duty otherwise existing at law, in equity or otherwise, to any Group Member or any Partner. None of any Group Member, any Limited Partner or any other Person shall have any rights by virtue of this Agreement, any Group Member Agreement, or the partnership relationship established hereby in any business ventures of any Indemnitee.

(c)    Notwithstanding anything to the contrary in this Agreement, (i) the engaging in competitive activities by any Indemnitees (other than the General Partner) in accordance with the provisions of this Section 7.5 is hereby approved by the Partnership and all Partners, (ii) it shall be deemed not to be a breach of any fiduciary duty or any other obligation of any type whatsoever of any Indemnitee for the Indemnitees (other than the General Partner) to engage in such business interests and activities in preference to or to the exclusion of the Partnership and (iii) the Indemnitees shall have no obligation hereunder or as a result of any duty otherwise existing at law, in equity or otherwise, to present business opportunities to the Partnership. Notwithstanding anything to the contrary in this Agreement, the doctrine of corporate opportunity, or any analogous doctrine, shall not apply to any Indemnitee (including the General Partner). No Indemnitee (including the General

Partner) who acquires knowledge of a potential transaction, agreement, arrangement or other matter that may be an opportunity for the Partnership, shall have any duty to communicate or offer such opportunity to the Partnership, and such Indemnitee (including the General Partner) shall not be liable to the Partnership, to any Limited Partner or any other Person for breach of any fiduciary or other duty by reason of the fact that such Indemnitee (including the General Partner) pursues or acquires for itself, directs such opportunity to another Person or does not communicate such opportunity or information to the Partnership; provided that such Indemnitee does not engage in such business or activity as a result of or using confidential or proprietary information provided by or on behalf of the Partnership to such Indemnitee.

(d)    The General Partner and each of its Affiliates may acquire Units or other Partnership Securities in addition to those owned as of the date hereof and, except as otherwise provided in this Agreement, shall be entitled to exercise, at their option, all rights relating to all Units or other Partnership Securities acquired by them. The term “ Affiliates ” when used in this Section 7.5(d) with respect to the General Partner shall not include any Group Member.

(e)    Notwithstanding anything to the contrary in this Agreement, to the extent that any provision of this Agreement purports or is interpreted to have the effect of restricting the fiduciary duties that might otherwise, as a result of Delaware or other applicable law, be owed by the General Partner to the Partnership and its Limited Partners, or to constitute a waiver or consent by the Limited Partners to any such restriction, such provisions shall be deemed to have been approved by the Partners.

Section 7.6     Loans from the General Partner; Loans or Contributions from the Partnership or Group Members .

(a)    The General Partner or any of its Affiliates may lend to any Group Member, and any Group Member may borrow from the General Partner or any of its Affiliates, funds needed or desired by the Group Member for such periods of time and in such amounts as the General Partner may determine; provided, however , that in any such case the lending party may not charge the borrowing party interest at a rate greater than the rate that would be charged the borrowing party or impose terms less favorable to the borrowing party than would be charged or imposed on the borrowing party by unrelated lenders on comparable loans made on an arm’s-length basis (without reference to the lending party’s financial abilities or guarantees), all as determined by the General Partner. The borrowing party shall reimburse the lending party for any costs (other than any additional interest costs) incurred by the lending party in connection with the borrowing of such funds. For purposes of this Section 7.6(a) and Section 7.6(b), the term “ Group Member ” shall include any Affiliate of a Group Member that is controlled by the Group Member.

(b)    The Partnership may lend or contribute to any Group Member, and any Group Member may borrow from the Partnership, funds on terms and conditions determined by the General Partner. Except for the Initial Loan, no Group Member may lend funds to the General Partner or any of its Affiliates (other than another Group Member).

(c)    No borrowing by any Group Member or the approval thereof by the General Partner shall be deemed to constitute a breach of any duty hereunder or otherwise existing at law, in equity

or otherwise, of the General Partner or its Affiliates to the Partnership or the Limited Partners by reason of the fact that the purpose or effect of such borrowing is directly or indirectly to enable distributions to the General Partner or its Affiliates (including in their capacities as Limited Partners) to exceed the General Partner’s Percentage Interest of the total amount distributed to all Partners.

Section 7.7     Indemnification .

(a)    To the fullest extent permitted by law but subject to the limitations expressly provided in this Agreement, all Indemnitees shall be indemnified and held harmless by the Partnership from and against any and all losses, claims, damages, liabilities, joint or several, expenses (including legal fees and expenses), judgments, fines, penalties, interest, settlements or other amounts arising from any and all claims, demands, actions, suits or proceedings, whether civil, criminal, administrative or investigative, in which any Indemnitee may be involved, or is threatened to be involved, as a party or otherwise, by reason of its status as an Indemnitee; provided that the Indemnitee shall not be indemnified and held harmless if there has been a final and non-appealable judgment entered by a court of competent jurisdiction determining that, in respect of the matter for which the Indemnitee is seeking indemnification pursuant to this Section 7.7, the Indemnitee acted in bad faith or engaged in fraud, willful misconduct or, in the case of a criminal matter, acted with knowledge that the Indemnitee’s conduct was unlawful; provided, further , no indemnification pursuant to this Section 7.7 shall be available to the General Partner or its Affiliates (other than a Group Member) with respect to its or their obligations incurred pursuant to the Underwriting Agreement, the Omnibus Agreement, the Secondment Agreement, the Contribution Agreement, the Tax Sharing Agreement or the Working Capital Agreement (other than obligations incurred by the General Partner on behalf of the Partnership). Any indemnification pursuant to this Section 7.7 shall be made only out of the assets of the Partnership, it being agreed that the General Partner shall not be personally liable for such indemnification and shall have no obligation to contribute or loan any monies or property to the Partnership to enable it to effectuate such indemnification.

(b)    To the fullest extent permitted by law, expenses (including legal fees and expenses) incurred by an Indemnitee who is indemnified pursuant to Section 7.7(a) in defending any claim, demand, action, suit or proceeding shall, from time to time, be advanced by the Partnership prior to a final and non-appealable judgment entered by a court of competent jurisdiction determining that, in respect of the matter for which the Indemnitee is seeking indemnification pursuant to this Section 7.7, the Indemnitee is not entitled to be indemnified.

(c)    The indemnification provided by this Section 7.7 shall be in addition to any other rights to which an Indemnitee may be entitled under any agreement, pursuant to any vote of the holders of Outstanding Limited Partner Interests, as a matter of law or otherwise, both as to actions in the Indemnitee’s capacity as an Indemnitee and as to actions in any other capacity (including any capacity under the Underwriting Agreement), and shall continue as to an Indemnitee who has ceased to serve in such capacity and shall inure to the benefit of the heirs, successors, assigns and administrators of the Indemnitee.

(d)    The Partnership may purchase and maintain (or reimburse the General Partner or its Affiliates for the cost of) insurance, on behalf of the General Partner, its Affiliates and such other Persons as the General Partner shall determine, against any liability that may be asserted against,

or expense that may be incurred by, such Person in connection with the Partnership’s activities or such Person’s activities on behalf of the Partnership, regardless of whether the Partnership would have the power to indemnify such Person against such liability under the provisions of this Agreement.

(e)    For purposes of this Section 7.7, the Partnership shall be deemed to have requested an Indemnitee to serve as fiduciary of an employee benefit plan whenever the performance by it of its duties to the Partnership also imposes duties on, or otherwise involves services by, it to the plan or participants or beneficiaries of the plan; excise taxes assessed on an Indemnitee with respect to an employee benefit plan pursuant to applicable law shall constitute “fines” within the meaning of Section 7.7(a); and action taken or omitted by it with respect to any employee benefit plan in the performance of its duties for a purpose reasonably believed by it to be in the best interest of the participants and beneficiaries of the plan shall be deemed to be for a purpose that is in the best interests of the Partnership.

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

(g)    An Indemnitee shall not be denied indemnification in whole or in part under this Section 7.7 because the Indemnitee had an interest in the transaction with respect to which the indemnification applies if the transaction was otherwise permitted by the terms of this Agreement.

(h)    The provisions of this Section 7.7 are for the benefit of the Indemnitees, their heirs, successors, assigns and administrators and shall not be deemed to create any rights for the benefit of any other Persons.

(i)    No amendment, modification or repeal of this Section 7.7 or any provision hereof shall in any manner terminate, reduce or impair the right of any past, present or future Indemnitee to be indemnified by the Partnership, nor the obligations of the Partnership to indemnify any such Indemnitee under and in accordance with the provisions of this Section 7.7 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted.

Section 7.8     Liability of Indemnitees .

(a)    Notwithstanding anything to the contrary set forth in this Agreement, no Indemnitee shall be liable for monetary damages to the Partnership, the Limited Partners, or any other Persons who have acquired interests in the Partnership Securities, for losses sustained or liabilities incurred as a result of any act or omission of an Indemnitee unless there has been a final and non-appealable judgment entered by a court of competent jurisdiction determining that, in respect of the matter in question, the Indemnitee acted in bad faith or engaged in fraud, willful misconduct or, in the case of a criminal matter, acted with knowledge that the Indemnitee’s conduct was criminal.

(b)    Subject to its obligations and duties as General Partner set forth in Section 7.1(a), the General Partner may exercise any of the powers granted to it by this Agreement and perform

any of the duties imposed upon it hereunder either directly or by or through its agents, and the General Partner shall not be responsible for any misconduct or negligence on the part of any such agent appointed by the General Partner in good faith.

(c)    To the extent that, at law or in equity, an Indemnitee has duties (including fiduciary duties) and liabilities relating thereto to the Partnership or to the Partners, the General Partner and any other Indemnitee acting in connection with the Partnership’s business or affairs shall not be liable to the Partnership or to any Partner for its good faith reliance on the provisions of this Agreement.

(d)    Any amendment, modification or repeal of this Section 7.8 or any provision hereof shall be prospective only and shall not in any way affect the limitations on the liability of the Indemnitees under this Section 7.8 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted.

Section 7.9     Resolution of Conflicts of Interest; Standards of Conduct and Modification of Duties .

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

Registration Statement are hereby approved by all Partners and shall not constitute a breach of this Agreement or any duty otherwise existing at law, in equity or otherwise.

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

(c)    Whenever the General Partner makes a determination or takes or declines to take any other action, or any of its Affiliates causes it to do so, in its individual capacity as opposed to in its capacity as the general partner of the Partnership, whether under this Agreement, any Group Member Agreement or any other agreement contemplated hereby or otherwise, then the General Partner, or such Affiliates causing it to do so, are entitled, to the fullest extent permitted by law, to make such determination or to take or decline to take such other action free of any duty (including any fiduciary duty) or obligation whatsoever to the Partnership, any Limited Partner, and any other Person bound by this Agreement, and the General Partner, or such Affiliates causing it to do so, shall not, to the fullest extent permitted by law, be required to act in good faith or pursuant to any other standard imposed by this Agreement, any Group Member Agreement, any other agreement contemplated hereby or under the Delaware Act or any other law, rule or regulation or at equity. By way of illustration and not of limitation, whenever the phrase, “at the option of the General Partner,” or some variation of that phrase, is used in this Agreement, it indicates that the General Partner is acting in its individual capacity. For the avoidance of doubt, whenever the General Partner votes or transfers its Partnership Interests, or refrains from voting or transferring its Partnership Interests, it shall be acting in its individual capacity. The General Partner’s organizational documents may provide that determinations to take or decline to take any action in its individual, rather than representative, capacity may or shall be determined by its members, if the General Partner is a limited liability company, stockholders, if the General Partner is a corporation, or the members or stockholders of the General Partner’s general partner, if the General Partner is a partnership.

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

(e)    Except as expressly set forth in this Agreement, neither the General Partner nor any other Indemnitee shall have any duties or liabilities, including fiduciary duties, to the Partnership or any Limited Partner and the provisions of this Agreement, to the extent that they restrict, eliminate or otherwise modify the duties and liabilities, including fiduciary duties, of the General Partner or any other Indemnitee otherwise existing at law or in equity, are agreed by the Partners to replace such other duties and liabilities of the General Partner or such other Indemnitee.

(f)    The Unitholders hereby authorize the General Partner, on behalf of the Partnership as a partner or member of a Group Member, to approve of actions by the general partner or managing member of such Group Member similar to those actions permitted to be taken by the General Partner pursuant to this Section 7.9.

Section 7.10     Other Matters Concerning the General Partner .

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

(b)    The General Partner may consult with legal counsel, accountants, appraisers, management consultants, investment bankers and other consultants and advisers selected by it, and any act taken or omitted to be taken in reliance upon the opinion (including an Opinion of Counsel) of such Persons as to matters that the General Partner reasonably believes to be within such Person’s professional or expert competence shall be conclusively presumed to have been done or omitted in good faith and in accordance with such opinion.

(c)    The General Partner shall have the right, in respect of any of its powers or obligations hereunder, to act through any of its duly authorized officers, a duly appointed attorney or attorneys-in-fact or the duly authorized officers of the Partnership or any Group Member.

Section 7.11     Purchase or Sale of Partnership Securities .

The General Partner may cause the Partnership to purchase or otherwise acquire Partnership Securities. Such Partnership Securities shall be held by the Partnership as treasury securities unless they are expressly cancelled by action of an appropriate officer of the General Partner. As long as Partnership Securities are held by any Group Member, such Partnership Securities shall not be considered Outstanding for any purpose, except as otherwise provided herein. The General Partner or any Affiliate of the General Partner may also purchase or otherwise acquire and sell or otherwise dispose of Partnership Securities for its own account, subject to the provisions of Articles IV and X.

Section 7.12     Registration Rights of the General Partner and its Affiliates .

(a)    If (i) the General Partner or any Affiliate of the General Partner (including for purposes of this Section 7.12, any Person that is an Affiliate of the General Partner at the date hereof notwithstanding that it may later cease to be an Affiliate of the General Partner) holds Partnership

Securities that it desires to sell and (ii) Rule 144 of the Securities Act (or any successor rule or regulation to Rule 144) or another exemption from registration is not available to enable such holder of Partnership Securities (the “ Holder ”) to dispose of the number of Partnership Securities it desires to sell at the time it desires to do so without registration under the Securities Act, then at the option and upon the request of the Holder, the Partnership shall file with the Commission as promptly as practicable after receiving such request, and use all commercially reasonable efforts to cause to become effective and remain effective for a period of not less than six months following its effective date or such shorter period as shall terminate when all Partnership Securities covered by such registration statement have been sold, a registration statement under the Securities Act registering the offering and sale of the number of Partnership Securities specified by the Holder; provided, however , that the Partnership shall not be required to effect more than three registrations pursuant to this Section 7.12(a) and Section 7.12(b); and provided, further, however , that if the Special Committee determines in good faith that the requested registration would be materially detrimental to the Partnership and its Partners because such registration would (x) materially interfere with a significant acquisition, reorganization or other similar transaction involving the Partnership, (y) require premature disclosure of material information that the Partnership has a bona fide business purpose for preserving as confidential or (z) render the Partnership unable to comply with requirements under applicable securities laws, then the Partnership shall have the right to postpone such requested registration for a period of not more than six months after receipt of the Holder’s request, such right pursuant to this Section 7.12(a) or Section 7.12(b) not to be utilized more than once in any twelve-month period. In connection with any registration pursuant to the first sentence of this Section 7.12(a), the Partnership shall (i) promptly prepare and file (A) such documents as may be necessary to register or qualify the securities subject to such registration under the securities laws of such states as the Holder shall reasonably request; provided , however , that no such qualification shall be required in any jurisdiction where, as a result thereof, the Partnership would become subject to general service of process or to taxation or qualification to do business as a foreign corporation or partnership doing business in such jurisdiction solely as a result of such registration, and (B) such documents as may be necessary to apply for listing or to list the Partnership Securities subject to such registration on such National Securities Exchange as the Holder shall reasonably request, and (ii) do any and all other acts and things that may be necessary or appropriate to enable the Holder to consummate a public sale of such Partnership Securities in such states. Except as set forth in Section 7.12(d), all costs and expenses of any such registration and offering (other than the underwriting discounts and commissions) shall be paid by the Partnership, without reimbursement by the Holder.

(b)    If any Holder holds Partnership Securities that it desires to sell and Rule 144 of the Securities Act (or any successor rule or regulation to Rule 144) or another exemption from registration is not available to enable such Holder to dispose of the number of Partnership Securities it desires to sell at the time it desires to do so without registration under the Securities Act, then at the option and upon the request of the Holder, the Partnership shall file with the Commission as promptly as practicable after receiving such request, and use its commercially reasonable efforts to cause to become effective and remain effective for a period of not less than six months following its effective date or such shorter period as shall terminate when all Partnership Securities covered by such shelf registration statement have been sold, a “shelf” registration statement covering the Partnership Securities specified by the Holder on an appropriate form under Rule 415 under the

Securities Act, or any similar rule that may be adopted by the Commission; provided, however , that the Partnership shall not be required to effect more than three registrations pursuant to Section 7.12(a) and this Section 7.12(b); and provided, further, however , that if the Special Committee determines in good faith that any offering under, or the use of any prospectus forming a part of, the shelf registration statement would be materially detrimental to the Partnership and its Partners because such offering or use would (x) materially interfere with a significant acquisition, reorganization or other similar transaction involving the Partnership, (y) require premature disclosure of material information that the Partnership has a bona fide business purpose for preserving as confidential or (z) render the Partnership unable to comply with requirements under applicable securities laws, then the Partnership shall have the right to suspend such offering or use for a period of not more than six months after receipt of the Holder’s request, such right pursuant to Section 7.12(a) or this Section 7.12(b) not to be utilized more than once in any twelve-month period. In connection with any shelf registration pursuant to this Section 7.12(b), the Partnership shall (i) promptly prepare and file (A) such documents as may be necessary to register or qualify the securities subject to such shelf registration under the securities laws of such states as the Holder shall reasonably request; provided, however , that no such qualification shall be required in any jurisdiction where, as a result thereof, the Partnership would become subject to general service of process or to taxation or qualification to do business as a foreign corporation or partnership doing business in such jurisdiction solely as a result of such shelf registration, and (B) such documents as may be necessary to apply for listing or to list the Partnership Securities subject to such shelf registration on such National Securities Exchange as the Holder shall reasonably request, and (ii) do any and all other acts and things that may be necessary or appropriate to enable the Holder to consummate a public sale of such Partnership Securities in such states. Except as set forth in Section 7.12(d), all costs and expenses of any such shelf registration and offering (other than the underwriting discounts and commissions) shall be paid by the Partnership, without reimbursement by the Holder.

(c)    If the Partnership shall at any time propose to file a registration statement under the Securities Act for an offering of equity securities of the Partnership for cash (other than an offering relating solely to an employee benefit plan), the Partnership shall notify all Holders of such proposals and use its commercially reasonable efforts to include such number or amount of securities held by the Holder in such registration statement as the Holder shall request; provided that the Partnership is not required to make any effort or take any action to so include the securities of the Holder once the registration statement is declared effective by the Commission or otherwise becomes effective, including any registration statement providing for the offering from time to time of securities pursuant to Rule 415 of the Securities Act. If the proposed offering pursuant to this Section 7.12(c) shall be an underwritten offering, then, in the event that the managing underwriter or managing underwriters of such offering advise the Partnership and the Holder in writing that in their opinion the inclusion of all or some of the Holder’s Partnership Securities would adversely and materially affect the success of the offering, the Partnership shall include in such offering only that number or amount, if any, of securities held by the Holder that, in the opinion of the managing underwriter or managing underwriters, will not so adversely and materially affect the offering. Except as set forth in Section 7.12(d), all costs and expenses of any such registration and offering (other than the underwriting discounts and commissions) shall be paid by the Partnership, without reimbursement by the Holder.

The Partners hereby agree that only the Events of Withdrawal described in this Section 11.1 shall result in the withdrawal of the General Partner from the Partnership.

(b)    Withdrawal of the General Partner from the Partnership upon the occurrence of an Event of Withdrawal shall not constitute a breach of this Agreement under the following circumstances: (i) at any time during the period beginning on the Closing Date and ending at 12:00 midnight, Central Standard Time, on June 30, 2018, the General Partner voluntarily withdraws by giving at least 90 days’ advance notice of its intention to withdraw to the Limited Partners; provided that prior to the effective date of such withdrawal, the withdrawal is approved by Unitholders holding at least a majority of the Outstanding Common Units (excluding Common Units held by the General Partner and its Affiliates) and the General Partner delivers to the Partnership an Opinion of Counsel (“ Withdrawal Opinion of Counsel ”) that such withdrawal (following the selection of the successor General Partner) would not result in the loss of the limited liability of any Limited Partner or any Group Member or cause any Group Member to be treated as an association taxable as a corporation or otherwise to be taxed as an entity for federal income tax purposes (to the extent not already so treated or taxed); (ii) at any time after 12:00 midnight, Central Standard Time, on June 30, 2018, the General Partner voluntarily withdraws by giving at least 90 days’ advance notice to the Unitholders, such withdrawal to take effect on the date specified in such notice; (iii) at any time that the General Partner ceases to be the General Partner pursuant to Section 11.1(a)(ii) or is removed pursuant to Section 11.2; or (iv) notwithstanding clause (i) of this sentence, at any time that the General Partner voluntarily withdraws by giving at least 90 days’ advance notice of its intention to withdraw to the Limited Partners, such withdrawal to take effect on the date specified in the notice, if at the time such notice is given one Person and its Affiliates (other than the General Partner and its Affiliates) own beneficially or of record or control at least 50% of the Outstanding Units.

Any successor General Partner elected in accordance with the terms of this Section 11.1 shall be subject to the provisions of Section 10.2.

Section 11.2     Removal of the General Partner .

The General Partner may be removed if such removal is approved by the Unitholders holding at least 66 2/3% of the Outstanding Units (including Units held by the General Partner and its Affiliates) voting as a single class. Any such action by such holders for removal of the General Partner must also provide for the election of a successor General Partner by the Unitholders holding a majority of the outstanding Common Units and Class B Units, if any, voting as a single class (including, in each case, Units held by the General Partner and its Affiliates). Such removal shall be effective immediately following the admission of a successor General Partner pursuant to Section 10.2. The removal of the General Partner shall also automatically constitute the removal of the General Partner as general partner or managing member, to the extent applicable, of the other Group Members of which the General Partner is a general partner or a managing member. If a Person is elected as a successor General Partner in accordance with the terms of this Section 11.2, such Person shall, upon admission pursuant to Section 10.2, automatically become a successor general partner or managing member, to the extent applicable, of the other Group Members of which the General Partner is a general partner or a managing member, and is hereby authorized to, and shall, continue the business of the Partnership, and, to the extent applicable, the other Group Members, without dissolution.

Any successor General Partner elected in accordance with the terms of this Section 11.2 shall be subject to the provisions of Section 10.2.

Section 11.3     Interest of Departing General Partner and Successor General Partner .

(a)    In the event of (i) withdrawal of the General Partner under circumstances where such withdrawal does not violate this Agreement or (ii) removal of the General Partner by the holders of Outstanding Units under circumstances where Cause does not exist, if the successor General Partner is elected in accordance with the terms of Section 11.1 or Section 11.2, the Departing General Partner shall have the option, exercisable prior to the effective date of the withdrawal or removal of such Departing General Partner, to require its successor to purchase its General Partner Interest (represented by General Partner Units) and its general partner interest (or equivalent interest), if any, in the other Group Members and all of its Incentive Distribution Rights (collectively, the “ Combined Interest ”) in exchange for an amount in cash equal to the fair market value of such Combined Interest, such amount to be determined and payable as of the effective date of its withdrawal or removal. If the General Partner is removed by the Unitholders under circumstances where Cause exists or if the General Partner withdraws under circumstances where such withdrawal violates this Agreement, and if a successor General Partner is elected in accordance with the terms of Section 11.1 or Section 11.2 (or if the business of the Partnership is continued pursuant to Section 12.2 and the successor General Partner is not the former General Partner), such successor shall have the option, exercisable prior to the effective date of the withdrawal or removal of such Departing General Partner (or, in the event the business of the Partnership is continued, prior to the date the business of the Partnership is continued), to purchase the Combined Interest for such fair market value of such Combined Interest of the Departing General Partner. In either event, the Departing General Partner shall be entitled to receive all reimbursements due such Departing General Partner pursuant to Section 7.4, including any employee-related liabilities (including severance liabilities),

incurred in connection with the termination of any employees employed by the Departing General Partner or its Affiliates (other than any Group Member) for the benefit of the Partnership or the other Group Members.

For purposes of this Section 11.3(a), the fair market value of the Departing General Partner’s Combined Interest shall be determined by agreement between the Departing General Partner and its successor or, failing agreement within 30 days after the effective date of such Departing General Partner’s withdrawal or removal, by an independent investment banking firm or other independent expert selected by the Departing General Partner and its successor, which, in turn, may rely on other experts, and the determination of which shall be conclusive as to such matter. If such parties cannot agree upon one independent investment banking firm or other independent expert within 45 days after the effective date of such departure, then the Departing General Partner shall designate an independent investment banking firm or other independent expert, the Departing General Partner’s successor shall designate an independent investment banking firm or other independent expert, and such firms or experts shall mutually select a third independent investment banking firm or independent expert, which third independent investment banking firm or other independent expert shall determine the fair market value of the Combined Interest of the Departing General Partner. In making its determination, such third independent investment banking firm or other independent expert may consider the then current trading price of Units on any National Securities Exchange on which Units are then listed or admitted to trading, the value of the Partnership’s assets, the rights and obligations of the Departing General Partner and other factors it may deem relevant.

(b)    If the Combined Interest is not purchased in the manner set forth in Section 11.3(a), the Departing General Partner (or its transferee) shall become a Limited Partner and its Combined Interest shall be converted into Common Units pursuant to a valuation made by an investment banking firm or other independent expert selected pursuant to Section 11.3(a), without reduction in such Partnership Interest (but subject to proportionate dilution by reason of the admission of its successor). Any successor General Partner shall indemnify the Departing General Partner (or its transferee) as to all debts and liabilities of the Partnership arising on or after the date on which the Departing General Partner (or its transferee) becomes a Limited Partner. For purposes of this Agreement, conversion of the Combined Interest of the Departing General Partner to Common Units will be characterized as if the Departing General Partner (or its transferee) contributed its Combined Interest to the Partnership in exchange for the newly issued Common Units.

(c)    If a successor General Partner is elected in accordance with the terms of Section 11.1 or Section 11.2 (or if the business of the Partnership is continued pursuant to Section 12.2 and the successor General Partner is not the former General Partner) and the option described in Section 11.3(a) is not exercised by the party entitled to do so, the successor General Partner shall, at the effective date of its admission to the Partnership, contribute to the Partnership cash in the amount equal to the product of (x) the quotient obtained by dividing (A) the Percentage Interest of the General Partner Interest of the Departing General Partner by (B) a percentage equal to 100% less the Percentage Interest of the General Partner Interest of the Departing General Partner and (y) the Net Agreed Value of the Partnership’s assets on such date. In such event, such successor General Partner shall, subject to the following sentence, be entitled to its Percentage Interest of all Partnership allocations and distributions to which the Departing General Partner was entitled. In addition, the

successor General Partner shall cause this Agreement to be amended to reflect that, from and after the date of such successor General Partner’s admission, the successor General Partner’s interest in all Partnership distributions and allocations shall be its Percentage Interest.

Section 11.4     Removal of the General Partner Not for Cause .

Notwithstanding any provision of this Agreement, if the General Partner is removed as general partner of the Partnership under circumstances where Cause does not exist and Units held by the General Partner and its Affiliates are not voted in favor of such removal, the General Partner will have the right to convert its General Partner Interest (represented by General Partner Units) and its Incentive Distribution Rights into Common Units or to receive cash in exchange therefor in accordance with Section 11.3.

Section 11.5     Withdrawal of Limited Partners .

No Limited Partner shall have any right to withdraw from the Partnership; provided, however , that when a transferee of a Limited Partner’s Limited Partner Interest becomes a Record Holder of the Limited Partner Interest so transferred, such transferring Limited Partner shall cease to be a Limited Partner with respect to the Limited Partner Interest so transferred.

Unless such an election is made within the applicable time period as set forth above, the Partnership shall conduct only activities necessary to wind up its affairs. If such an election is so made, then:

(iv)     provided that the right of the holders of a Unit Majority to approve a successor General Partner and to continue the business of the Partnership shall not exist and may not be exercised unless the Partnership has received an Opinion of Counsel that (x) the exercise of the right would not result in the loss of limited liability of any Limited Partner and (y) neither the Partnership nor any Group Member would be treated as an association taxable as a corporation or otherwise be taxable as an entity for federal income tax purposes upon the exercise of such right to continue (to the extent not already so treated or taxed).

Section 12.3     Liquidator .

Upon dissolution of the Partnership, unless the business of the Partnership is continued pursuant to Section 12.2, the General Partner shall select one or more Persons to act as Liquidator. The Liquidator (if other than the General Partner) shall be entitled to receive such compensation for its services as may be approved by holders of at least a majority of the Outstanding Common Units and Class B Units, if any, voting as a single class. The Liquidator (if other than the General Partner) shall agree not to resign at any time without 15 days’ prior notice and may be removed at any time, with or without cause, by notice of removal approved by holders of at least a majority of the Outstanding Common Units and Class B Units, if any, voting as a single class. Upon dissolution, removal or resignation of the Liquidator, a successor and substitute Liquidator (who shall have and succeed to all rights, powers and duties of the original Liquidator) shall within 30 days thereafter be approved by holders of at least a majority of the Outstanding Common Units and Class B Units, if any, voting as a single class. The right to approve a successor or substitute Liquidator in the manner provided herein shall be deemed to refer also to any such successor or substitute Liquidator approved in the manner herein provided. Except as expressly provided in this Article XII, the

Liquidator approved in the manner provided herein shall have and may exercise, without further authorization or consent of any of the parties hereto, all of the powers conferred upon the General Partner under the terms of this Agreement (but subject to all of the applicable limitations, contractual and otherwise, upon the exercise of such powers, other than the limitation on sale set forth in Section 7.3) necessary or appropriate to carry out the duties and functions of the Liquidator hereunder for and during the period of time required to complete the winding up and liquidation of the Partnership as provided for herein.

(a)    The assets may be disposed of by public or private sale or by distribution in kind to one or more Partners on such terms as the Liquidator and such Partner or Partners may agree. If any property is distributed in kind, the Partner receiving the property shall be deemed for purposes of Section 12.4(c) to have received cash equal to its fair market value; and contemporaneously therewith, appropriate cash distributions must be made to the other Partners. The Liquidator may defer liquidation or distribution of the Partnership’s assets for a reasonable time if it determines that an immediate sale or distribution of all or some of the Partnership’s assets would be impractical or would cause undue loss to the Partners. The Liquidator may distribute the Partnership’s assets, in whole or in part, in kind if it determines that a sale would be impractical or would cause undue loss to the Partners.

(b)    Liabilities of the Partnership include amounts owed to the Liquidator as compensation for serving in such capacity (subject to the terms of Section 12.3) and amounts to Partners otherwise than in respect of their distribution rights under Article VI. With respect to any liability that is contingent, conditional or unmatured or is otherwise not yet due and payable, the Liquidator shall either settle such claim for such amount as it thinks appropriate or establish a reserve of cash or other assets to provide for its payment. When paid, any unused portion of the reserve shall be distributed as additional liquidation proceeds.

(c)    All property and all cash in excess of that required to discharge liabilities as provided in Section 12.4(b) shall be distributed to the Partners in accordance with, and to the extent of, the positive balances in their respective Capital Accounts, as determined after taking into account all Capital Account adjustments (including, without limitation, the allocation provided for under Section 6.1(d)(xi)(C), which allocates items of gross income, gain, loss and deduction among the Partners to the maximum extent possible to provide a preference in liquidation to the Capital Account of the Series A Preferred Units over the Capital Accounts of Series A Junior Interests, but excluding adjustments made by reason of distributions pursuant to this Section 12.4(c)) for the taxable period of the Partnership during which the liquidation of the Partnership occurs (with such date of occurrence being determined pursuant to Treasury Regulation Section 1.704-1(b)(2)(ii)(g)), and such distribution shall be made by the end of such taxable period (or, if later, within 90 days after said date of such occurrence).

Section 12.5     Cancellation of Certificate of Limited Partnership .

Upon the completion of the distribution of Partnership cash and property as provided in Section 12.4 in connection with the liquidation of the Partnership, the Certificate of Limited Partnership and all qualifications of the Partnership as a foreign limited partnership in jurisdictions other than the State of Delaware shall be canceled and such other actions as may be necessary to terminate the Partnership shall be taken.

Section 12.6     Return of Contributions .

The General Partner shall not be personally liable for, and shall have no obligation to contribute or loan any monies or property to the Partnership to enable it to effectuate, the return of the Capital Contributions of the Limited Partners or Unitholders, or any portion thereof, it being expressly understood that any such return shall be made solely from Partnership assets.

Section 12.7     Waiver of Partition .

To the maximum extent permitted by law, each Partner hereby waives any right to partition of the Partnership property.

Section 12.8     Capital Account Restoration .

No Limited Partner shall have any obligation to restore any negative balance in its Capital Account upon liquidation of the Partnership. The General Partner shall be obligated to restore any negative balance in its Capital Account upon liquidation of its interest in the Partnership by the end of the taxable period of the Partnership during which such liquidation occurs, or, if later, within 90 days after the date of such liquidation.

The General Partner shall notify all Record Holders upon final adoption of any such proposed amendments.

Section 13.3     Amendment Requirements .

(b)    Notwithstanding the provisions of Section 13.1 and Section 13.2, no amendment to this Agreement may (i) enlarge the obligations of any Limited Partner without its consent, unless such shall be deemed to have occurred as a result of an amendment approved pursuant to Section 13.3(c), or (ii) enlarge the obligations of, restrict in any way any action by or rights of, or reduce in any way the amounts distributable, reimbursable or otherwise payable to, the General Partner or any of its Affiliates without its consent, which consent may be given or withheld at its option.

Limited Partners shall call a special meeting by delivering to the General Partner one or more requests in writing stating that the signing Limited Partners wish to call a special meeting and indicating the general or specific purposes for which the special meeting is to be called. Within 60 days after receipt of such a call from Limited Partners or within such greater time as may be reasonably necessary for the Partnership to comply with any statutes, rules, regulations, listing agreements or similar requirements governing the holding of a meeting or the solicitation of proxies for use at such a meeting, the General Partner shall send a notice of the meeting to the Limited Partners either directly or indirectly through the Transfer Agent. A meeting shall be held at a time and place determined by the General Partner on a date not less than 10 days nor more than 60 days after the time notice of the meeting is given as provided in Section 16.1. Limited Partners shall not vote on matters that would cause the Limited Partners to be deemed to be taking part in the management and control of the business and affairs of the Partnership so as to jeopardize the Limited Partners’ limited liability under the Delaware Act or the law of any other state in which the Partnership is qualified to do business.

Section 13.5     Notice of a Meeting .

Notice of a meeting called pursuant to Section 13.4 shall be given to the Record Holders of the class or classes of Units for which a meeting is proposed in writing by mail or other means of written communication in accordance with Section 16.1.

Section 13.6     Record Date .

For purposes of determining the Limited Partners entitled to notice of or to vote at a meeting of the Limited Partners or to give approvals without a meeting as provided in Section 13.11 the General Partner may set a Record Date, which shall not be less than 10 nor more than 60 days before (a) the date of the meeting (unless such requirement conflicts with any rule, regulation, guideline or requirement of any National Securities Exchange on which the Units are listed or admitted to trading, in which case the rule, regulation, guideline or requirement of such National Securities Exchange shall govern) or (b) in the event that approvals are sought without a meeting, the date by which Limited Partners are requested in writing by the General Partner to give such approvals.

At the adjourned meeting, the Partnership may transact any business which might have been transacted at the original meeting. If the adjournment is for more than 45 days or if a new Record Date is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given in accordance with this Article XIII.

Section 13.8     Waiver of Notice; Approval of Meeting; Approval of Minutes .

The transactions of any meeting of Limited Partners, however called and noticed, and whenever held, shall be as valid as if it had occurred at a meeting duly held after regular call and notice, if a quorum is present either in person or by proxy. Attendance of a Limited Partner at a meeting shall constitute a waiver of notice of the meeting, except when the Limited Partner attends the meeting for the express purpose of objecting, at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened; and except that attendance at a meeting is not a waiver of any right to disapprove the consideration of matters required to be included in the notice of the meeting, but not so included, if the disapproval is expressly made at the meeting.

Section 13.9     Quorum and Voting .

The holders of a majority of the Outstanding Units of the class or classes for which a meeting has been called (including Outstanding Units deemed owned by the General Partner) represented in person or by proxy shall constitute a quorum at a meeting of Limited Partners of such class or classes unless any such action by the Limited Partners requires approval by holders of a greater percentage of such Units, in which case the quorum shall be such greater percentage. At any meeting of the Limited Partners duly called and held in accordance with this Agreement at which a quorum is present, the act of Limited Partners holding Outstanding Units that in the aggregate represent a

majority of the Outstanding Units entitled to vote and be present in person or by proxy at such meeting shall be deemed to constitute the act of all Limited Partners, unless a greater or different percentage is required with respect to such action under the provisions of this Agreement, in which case the act of the Limited Partners holding Outstanding Units that in the aggregate represent at least such greater or different percentage shall be required. The Limited Partners present at a duly called or held meeting at which a quorum is present may continue to transact business until adjournment, notwithstanding the withdrawal of enough Limited Partners to leave less than a quorum, if any action taken (other than adjournment) is approved by the required percentage of Outstanding Units specified in this Agreement (including Outstanding Units deemed owned by the General Partner). In the absence of a quorum any meeting of Limited Partners may be adjourned from time to time by the affirmative vote of holders of at least a majority of the Outstanding Units entitled to vote at such meeting (including Outstanding Units deemed owned by the General Partner) represented either in person or by proxy, but no other business may be transacted, except as provided in Section 13.7.

Section 13.10     Conduct of a Meeting .

The General Partner shall have full power and authority concerning the manner of conducting any meeting of the Limited Partners or solicitation of approvals in writing, including the determination of Persons entitled to vote, the existence of a quorum, the satisfaction of the requirements of Section 13.4, the conduct of voting, the validity and effect of any proxies and the determination of any controversies, votes or challenges arising in connection with or during the meeting or voting. The General Partner shall designate a Person to serve as chairman of any meeting and shall further designate a Person to take the minutes of any meeting. All minutes shall be kept with the records of the Partnership maintained by the General Partner. The General Partner may make such other regulations consistent with applicable law and this Agreement as it may deem advisable concerning the conduct of any meeting of the Limited Partners or solicitation of approvals in writing, including regulations in regard to the appointment of proxies, the appointment and duties of inspectors of votes and approvals, the submission and examination of proxies and other evidence of the right to vote, and the revocation of approvals in writing.

Section 13.11     Action Without a Meeting .

If authorized by the General Partner, any action that may be taken at a meeting of the Limited Partners may be taken without a meeting, without a vote and without prior notice, if an approval in writing setting forth the action so taken is signed by Limited Partners owning not less than the minimum percentage of the Outstanding Units (including Units deemed owned by the General Partner) that would be necessary to authorize or take such action at a meeting at which all the Limited Partners were present and voted (unless such provision conflicts with any rule, regulation, guideline or requirement of any National Securities Exchange on which the Units are listed or admitted to trading, in which case the rule, regulation, guideline or requirement of such National Securities Exchange shall govern). Prompt notice of the taking of action without a meeting shall be given to the Limited Partners who have not approved in writing. The General Partner may specify that any written ballot, if any, submitted to Limited Partners for the purpose of taking any action without a meeting shall be returned to the Partnership within the time period, which shall be not

less than 20 days, specified by the General Partner. If a ballot returned to the Partnership does not vote all of the Units held by the Limited Partners, the Partnership shall be deemed to have failed to receive a ballot for the Units that were not voted. If approval of the taking of any action by the Limited Partners is solicited by any Person other than by or on behalf of the General Partner, the written approvals shall have no force and effect unless and until (a) they are deposited with the Partnership in care of the General Partner, (b) approvals sufficient to take the action proposed are dated as of a date not more than 90 days prior to the date sufficient approvals are deposited with the Partnership and (c) an Opinion of Counsel is delivered to the General Partner to the effect that the exercise of such right and the action proposed to be taken with respect to any particular matter (i) will not cause the Limited Partners to be deemed to be taking part in the management and control of the business and affairs of the Partnership so as to jeopardize the Limited Partners’ limited liability, and (ii) is otherwise permissible under the state statutes then governing the rights, duties and liabilities of the Partnership and the Partners. Nothing contained in this Section 13.11 shall be deemed to require the General Partner to solicit all Limited Partners in connection with a matter approved by the holders of the percentage of Units acting by written consent without a meeting.

Section 13.12     Right to Vote and Related Matters .

(a)    Only those Record Holders of the Outstanding Units on the Record Date set pursuant to Section 13.6 (and also subject to the limitations contained in the definition of “ Outstanding ”) shall be entitled to notice of, and to vote at, a meeting of Limited Partners or to act with respect to matters as to which the holders of the Outstanding Units have the right to vote or to act. All references in this Agreement to votes of, or other acts that may be taken by, the Outstanding Units shall be deemed to be references to the votes or acts of the Record Holders of such Outstanding Units.

(b)    With respect to Units that are held for a Person’s account by another Person (such as a broker, dealer, bank, trust company or clearing corporation, or an agent of any of the foregoing), in whose name such Units are registered, such other Person shall, in exercising the voting rights in respect of such Units on any matter, and unless the arrangement between such Persons provides otherwise, vote such Units in favor of, and at the direction of, the Person who is the beneficial owner, and the Partnership shall be entitled to assume it is so acting without further inquiry. The provisions of this Section 13.12(b) (as well as all other provisions of this Agreement) are subject to the provisions of Section 4.3.
