PARTNERS; REPRESENTATIONS

Section 3.01 Redesignation of Units

(a) The Redesignation of the formerly designated Class A Units and Class B Units as a single class of Units is effective as at the Redesignation Date. As at the Redesignation Date, (i) the holders of Units (Capital), in such capacity and with respect to such Units (Capital), shall have only the rights and obligations attached to the Units (Capital) of the Partnership, and not those attached to the Units (Profits Interest) of the Partnership, and (ii) the holders of Units (Profits Interest), in such capacity and with respect to such Units (Profits Interest), shall have only the rights and obligations attached to the Units (Profits Interest) of the Partnership, and not those attached to the Units (Capital) of the Partnership. It is recognized that the Redesignation did not change the substantive rights and obligations of the holders of the formerly designated Class A Units and Class B Units and, consistent therewith, for all U.S. federal, state and local income tax purposes, the Partnership and each Partner shall treat (x) the Redesignation as having no effect and (y) consistent with clause (x), the Units held by each Partner immediately after the Redesignation as the same Units held by such Partner immediately prior to the Redesignation.

(b) The rights and obligations of the formerly designated Class A Units and Class B Units prior to the Redesignation Date are set forth in the Second A&R LPA.

Section 3.02 Units (Capital) Limited Partners

The identity of all of the Units (Capital) Limited Partners and the number of Units held by each Units (Capital) Limited Partner are reflected on Exhibit B attached hereto, which shall be amended as necessary by the Board of Directors to reflect any changes in such information. The Partnership is authorized to issue additional Units (Capital) at a price of $1.00 per Unit (unless otherwise provided herein or as otherwise determined by the Board of Directors) and admit

20

additional Units (Capital) Limited Partners only after (a) the Board of Directors consents thereto, (b) so long as the Riverstone Group holds the Units (Capital) Majority, Riverstone consents thereto, (c) each such additional Units (Capital) Limited Partner pays any Capital Contribution required by the Board of Directors and (d) each such additional Units (Capital) Limited Partner executes an Adoption Agreement and any other documents in form and substance as the Board of Directors may deem necessary or desirable to effect such admission. The issuance of additional Units (Capital) shall dilute the Units (Capital) Limited Partners pro rata.

Section 3.03 Units (Profits Interest) Limited Partners

(a) The Partnership shall have the authority to issue not more than 1,000,000 Units (Profits Interest) of which 835,000 Units (Profits Interest) are outstanding on the date of this Agreement. Units (Profits Interest) shall be issuable only to Employees or to Management Holdco. The identity of all of the Units (Profits Interest) Limited Partners and the number of Units held by each Units (Profits Interest) Limited Partner as of the date of this Agreement are reflected on Exhibit D attached hereto, which shall be amended as necessary by the Board of Directors to reflect any changes in such information. The remaining 165,000 authorized but unissued Units (Profits Interest) may be issued, and the Persons to whom they are issued may be admitted as additional Units (Profits Interest) Limited Partners, only by the Board of Directors, with the consent of the Units (Profits Interest) Majority. As a condition to the issuance of the Units (Profits Interest), each such additional Units (Profits Interest) Limited Partner shall execute an Adoption Agreement and any other instruments in form and substance as the Board of Directors may deem necessary or desirable to effect such admission if such Person is not already a Units (Profits Interest) Limited Partner. The issuance of such remaining 165,000 authorized but unissued Units (Profits Interest) shall dilute the Units (Profits Interest) Limited Partners pro rata subject to the Threshold Amount provisions of Section 3.03(c). No Units (Profits Interest) shall be issued following the first to occur of (i) a Qualified Public Offering, (ii) a Liquidation Event, (iii) a Transfer after the Effective Date in a single transaction or a series of related transactions of 50% or more of the Units (Capital), and (iv) a Reorganization.

(b) The Units (Profits Interest) are intended to constitute “profits interests” within the meaning of Revenue Procedures 93-27 and 2001-43 (or the corresponding requirements of any subsequent guidance promulgated by the Internal Revenue Service or other applicable law). Accordingly, the Capital Account associated with each Units (Profits Interest) at the time of its issuance shall be equal to zero dollars ($0.00). The Partnership and the holders of Units (Profits Interest) shall file all federal income tax returns consistent with such characterization.

(c) The Partnership may from time to time effect one or more additional issuances of tranches of Units (Profits Interest), in accordance with the provisions of Section 3.03(a), the first of which to be issued after the Effective Date shall be designated as Units (Profits Interest)-2 and each subsequent issuance shall be designated by a sequential number (Units (Profits Interest)-3, Units (Profits Interest)-4, etc.). Each tranche of Units (Profits Interest) shall have a “Threshold Amount” to the extent necessary to cause such Units (Profits Interest) to constitute “profits interests” as provided in Section 3.03(b) of this Agreement, but not less than zero (taking into

21

account the adjustments to Book Value contemplated in clause (ii) of subparagraph (b) of the definition thereof). The Threshold Amount of each Class B Unit (and after the Redesignation, Unit (Profits Interest)) issued on the Initial Closing Date (designated herein as a “Unit (Profits Interest)-1”) was zero (0). The Threshold Amount for each other tranche of Units (Profits Interest) shall equal the amount that would, in the reasonable determination of the Board of Directors, be distributable with respect to each then outstanding Unit (Profits Interest) of any then outstanding tranche of Units (Profits Interest) if, immediately prior to the issuance of such additional tranche of Units (Profits Interest), the assets of the Partnership were sold for their fair market value and the proceeds (net of any liabilities of the Partnership) were distributed pursuant to Section 7.01 of this Agreement.

Section 3.04 Units; Certificates

Units may be (but need not be) represented by certificates in such form as the Board of Directors shall from time to time approve, but shall be recorded in a register thereof maintained by the Partnership, and shall be subject to such rules for the issuance thereof as the Board of Directors may from time to time determine. If the Board of Directors elects to certificate the Units and a mutilated Unit is surrendered to the Partnership or if the Partner claims and submits an affidavit or other evidence, satisfactory to the Partnership, to the effect that the Unit has been lost, destroyed or wrongfully taken, the Partnership shall issue a replacement Unit if the Partnership’s requirements are met. If required by the Partnership, such Partner must provide an indemnity bond, or other form of indemnity, sufficient in the judgment of the Partnership to protect the Partnership against any loss which may be suffered. The Partnership may charge such Partner for its reasonable out-of-pocket expenses in replacing a Unit which has been mutilated, lost, destroyed or wrongfully taken. For the avoidance of doubt, the Partnership may issue fractional Units.

(e) Resolution of Conflicts of Interest. Unless otherwise expressly provided in this Agreement, whenever a potential conflict of interest exists or arises between the General Partner or any of its Affiliates, or any Officer or member of the Board of Directors, on the one hand, and the Partnership, any Partner or any Transferee, on the other hand, any resolution or course of action 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 agreement contemplated herein, or of any standard of care or duty stated or implied by law or equity, if the resolution or course of action is or, by operation of this Agreement is deemed to be, fair and reasonable to the Partnership. Any conflict of interest and any resolution of such conflict of interest shall be conclusively deemed fair and reasonable to the Partnership if such conflict of interest or resolution is (i) on terms no less favorable to the Partnership than those generally being provided to or available from unrelated third parties or (ii) fair 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 Board of Directors shall be authorized in connection with its determination of what is “fair and reasonable” to the Partnership and in connection with its resolution of any conflict of interest to consider (i) the relative interests of any party to such conflict, agreement, transaction or situation and the benefits and burdens relating to such interest; (ii) any customary or accepted industry practices and any customary or historical dealings with a particular Person; (iii) any applicable generally accepted accounting or engineering practices or principles; and (iv) such additional factors as the Board of Directors determines in its sole discretion to be relevant, reasonable or appropriate under the circumstances. For the avoidance of doubt, (A) with respect to the parties to the Non-Competition Agreement, any activity, action or transaction allowed under the Non-Competition Agreement or the Initial Limited Partner LPA, (B) to the extent a Limited Partner is an Employee, any employment relationship between such Limited Partner and an entity that is a member of the PEG Group, or (C) ownership of equity in, and service as an officer, director, authorized signatory, manager, or other governance position for, an entity that is a member of the PEG Group, shall not be treated as a conflict of interest for purposes of this Agreement. Nothing contained in this Agreement, however, is intended to nor shall it be construed to require the Board of Directors to consider the interest of any Person other than the Partnership. So long as the Board of Directors acts in good faith, the resolution, action or terms so made, taken or provided by the Board of Directors with respect to such matter shall not constitute a breach of this Agreement or any other agreement contemplated herein or a breach of any standard of care or duty stated or implied by law or equity.

(f) No Duty to Consider Other Interests. Whenever this Agreement or any other agreement contemplated hereby provides that the Board of Directors is permitted or required to make a decision (i) in its “sole discretion” or “discretion,” that it deems “necessary or appropriate” or under a grant of similar authority or latitude, the Board of Directors shall be entitled to consider only such interests and factors as it desires and shall have no duty or obligation to give any

24

consideration to any interest of, or factors affecting, the Partnership, any Partner or any Transferee, (ii) it will make such decision in good faith unless another express standard is provided for, or (iii) in “good faith” or under another express standard, the Board of Directors shall act under such express standard and shall not be subject to any other or different standards imposed by this Agreement or any other agreement contemplated hereby or under the Act or any other law, rule or regulation.

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

(h) Garland Conflict of Interest. Notwithstanding anything else in this Partnership Agreement or ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇’▇ Employment Agreement to the contrary, each of the Partners (in their own names and on behalf of the Partnership) hereby acknowledge, agree and affirm that:

(i) ▇▇. ▇▇▇▇▇▇▇ holds a position on the board of directors and the investment committee of the SteelRiver Entities and may continue to hold such positions and devote such time as is reasonably required to perform such duties;

(ii) ▇▇. ▇▇▇▇▇▇▇ owns an economic interest in the SteelRiver Entities and any conflict of interest resulting from such economic interest is hereby waived; provided, however, that ▇▇. ▇▇▇▇▇▇▇ agrees to notify the Partnership of any substantial increases in his economic interest in the SteelRiver Entities by virtue of amendments to the constitutive documents of the SteelRiver Entities or additional investments;

(iii) ▇▇. ▇▇▇▇▇▇▇ shall be under no obligation to disclose confidential information (whether confidentiality arises by operation of law or contract and whether or not such information represents a business opportunity) of, or related to, the SteelRiver Entities, including, without limitation confidential information relating to business opportunities (or to the SteelRiver Entities’ pursuit, acquisition and consummation of such opportunities);

(iv) ▇▇. ▇▇▇▇▇▇▇ is hereby authorized to disclose the provisions of this Section 3.05(h) to the board of directors of the SteelRiver Entities; and

(v) Any duty or other obligation, if any, that ▇▇. ▇▇▇▇▇▇▇ may have to the Partnership or another Partner, pursuant to the Act or any other applicable law, rule or regulation, is waived to the extent necessary to give effect to the terms of this Section 3.05(h).

(b) to adopt an appropriate federal income tax method of accounting and to keep the Partnership’s books and records on such income tax method;

(d) any other election the Board of Directors may deem appropriate and in the best interests of the Partnership.

Section 4.03 Partnership Representative

(a) For taxable years of the Partnership beginning before January 1, 2018, Sections 4.03(a) – (f) of the Second A&R LPA shall continue to apply in lieu of Section 4.03(b) – (g) of this Agreement.

(b) The “Partnership Representative” of the Partnership pursuant to Code Section 6223(a)for taxable years of the Partnership beginning on or after January 1, 2018 shall be an eligible Partner designated from time to time by the Board of Directors subject to replacement by the Board of Directors. (Any Partner who is designated as the partnership representative is referred to herein as the “Partnership Representative”). The initial Partnership Representative will be the General Partner and may be changed only upon Board Approval and in accordance with the Code and applicable Treasury Regulations. The Partnership shall designate the “Designated Individual” identified by the Partnership Representative through whom it shall act in its capacity as Partnership Representative; provided that the Designated Individual must be subject to the control of the Partnership Representative.

28

(c) The Partnership Representative (x) will (or will cause the Company to) give notice to the other Partners of any audit, administrative or judicial proceedings, meetings or conferences with the Internal Revenue Service or other similar matters that come to its attention, and (y) will make the election contemplated by Section 6226 of the Code, and follow the procedures required in connection with that election to make inapplicable to the Partnership the requirement in Section 6225 of the Code that the Partnership pay any “imputed underpayment” as that term is used in such section, unless the Board of Directors determines that such election is not in the best interests of the Partnership and the Partners taken as a whole.

(d) In the event that the Partnership is issued a notice of proposed partnership adjustment, the Partnership Representative will undertake the “pull-in” procedure contemplated by Code Section 6225(c)(2)(B) with respect to such adjustment in order to reduce the final partnership adjustment, and to the extent that the “pull-in” procedure does not reduce the partnership adjustment amount to zero, the Partnership Representative will make the “push-out” election contemplated by Code Section 6226(a) with respect to any remaining deficiency in a timely manner, provided that the “push-out” election is available to the Partnership and the Board of Directors has not directed otherwise as set forth in Section 4.03(c).

(e) The Partnership Representative is authorized to take such actions and to execute and file all statements and forms and tax returns on behalf of the Partnership which may be permitted or required by the applicable provisions of the Code or Treasury Regulations issued thereunder, provided that the Partnership Representative may file suit only with Board of Director approval. The Partnership Representative shall act in a similar capacity under any applicable non-U.S., state or local tax law. The Partnership Representative will not cause the Partnership to be treated as other than a “partnership” for federal income tax purposes. All out-of-pocket expenses incurred by the Partnership Representative while acting in such capacity shall be paid or reimbursed by the Partnership.

(f) The Partnership Representative shall have the exclusive right and sole authority to act on behalf of the Partnership under Subchapter C of Section 63 of the Code (relating to Internal Revenue Service partnership audit proceedings) and in any tax proceedings brought by other taxing authorities, and the Partnership and all Partners shall be bound by the actions taken by the Partnership Representative in such capacity. The Partnership Representative shall keep the Partners informed on a timely basis of all material developments with respect to any such proceeding and shall inform the Partners of any material decision or actions it takes in its capacity as Partnership Representative.

(g) In the event of any “imputed underpayment” within the meaning of Section 6225 of the Code paid by the Partnership as a result of an adjustment with respect to any Partnership item, including any interest or penalties with respect to any such adjustment (collectively, an “Imputed Underpayment Amount”), the Partnership Representative shall use commercially reasonable efforts to allocate the burden of (or any decrease in Distributable Property resulting from) any taxes, penalties or interest imposed on the Partnership pursuant to Code Sections 6225 and 6232 among the Partners and former Partners in a reasonable manner based on the status, actions, inactions or other attributes of each Partner and taking into account whether such Partner has filed an amended return for its taxable year that includes the end of the reviewed year of the Partnership and paid any tax due shown thereon in order to modify or reduce the amount of the Imputed

29

Adjustment Amount under Section 6225(c)(2). Any amounts allocated to a Partner pursuant to the preceding sentence will be treated as withholding tax that arises as a result of the status or other matters that are particular to a Partner. If the Partnership becomes liable for any taxes, interest or penalties under Section 6225 of the Code (following a final determination of such liability by the relevant governmental authority), each Partner that was a Partner of the Partnership for the taxable year to which such liability relates shall indemnify and hold harmless the Partnership for such Person’s allocable share of the amount of such tax liability, including any interest and penalties associated therewith, as reasonably determined by the Partnership Representative.

(h) Each Partner acknowledges and agrees that (i) it is required to provide the Partnership Representative with any reasonable requested documents, information, assistance or cooperation in connection with the requirements imposed on the Partnership pursuant to Sections 6221 through 6241 of the Code, together with any guidance issued thereunder, including (i) information as to a Partner’s (or any direct or indirect interest holder of a Partner’s) status as a “tax-exempt entity” (within the meaning of Section 168(h)(2) of the Code), a real estate investment trust, or a regulated investment company under the Code, (ii) the extent to which a tax-exempt entity Partner (or direct or indirect interest holder of a Partner) was subject to the “unrelated business income tax” under Section 512 of the Code a taxable year, (iii) information regarding a Partner’s (or any direct or indirect interest holder of a Partner’s) status as an individual, C corporation or S corporation, and (iv) and any other information required by guidance issued under Section 6225(c)(5) of the Code or that the Partnership Representative otherwise reasonably deems relevant in order to modify the Partnership’s imputed underpayment as permitted under Section 6225(c), and (ii) if it fails to provide such documentation, information, assistance or cooperation (including as a result of a Partner not being eligible to provide any requested documentation), any taxes, penalties or interest imposed on the Partnership as a result of such failure will be treated for all purposes of this Agreement including Section 7.06) as amounts that are determined by reference to the status of a Partner (or its beneficial owners).

(i) Each Partner agrees that, in the case of any direct disposition by such Partner, such Partner shall remain liable for any indemnification obligations set forth under clause (g) above which could be owed by such Partner in respect of the time periods preceding the effective date of the disposition, unless the transferee of its Partnership Interest expressly assumes its indemnification liability under Section 4.03(g) with respect to such preceding periods.

Section 4.04 Section 83(b) Election

Each Partner who acquires Units (Profits Interest) and who is a United States person within the meaning of Code Section 7701(a)(30) shall file a timely election under Code Section 83(b) with respect to such Units and consult with such Partner’s tax advisor to determine the tax consequences of such acquisition and of filing an election under Code Section 83(b). Each such Partner acknowledges that it is the sole responsibility of such Partner, and not the Partnership, to file the election under Code Section 83(b) even if such Partner requests the Partnership to assist in making such filing.

ARTICLE V

CAPITAL CONTRIBUTIONS

Section 5.01 Initial Capital Contributions of Units (Capital) Limited Partners

(a) On the Initial Closing Date, in connection with the contributions by the Initial Limited Partner pursuant to the Contribution Agreement, each of the Initial Contributing Partners was deemed to have contributed to the Partnership (a) assets with a Book Value in the amount set forth opposite such Partner’s name on Exhibit A under the heading “Initial Contributed Assets”, and received, following a distribution of the Units (Capital) issued to the Initial Limited Partner pursuant to the Contribution Agreement, the number of Units (Capital) set forth opposite such Units (Capital) Limited Partner’s name under the heading “Contributed Assets Units (Capital)”, and (b) the amount set forth opposite such Units (Capital) Limited Partner’s name on Exhibit A under the heading “Capital Contributions”, and received, following the distribution of the Units (Capital) issued to the Initial Limited Partner pursuant to the Contribution Agreement, the number of Units (Capital) set forth opposite such Partner’s name under the heading “Capital Contribution Units (Capital)” on Exhibit A hereto. Notwithstanding the distribution on the Initial Closing Date by the Initial Limited Partner of such Units (Capital) to its limited partners, the Initial Limited Partner shall remain a Units (Capital) Limited Partner under this Agreement.

(b) Within ten (10) Business Days after the Effective Date, each Effective Date Contributing Partner contributed to the Partnership, in readily available funds, the amounts set forth opposite such Effective Date Contributing Partner’s name in Exhibit A, and received therefore the number of Class A Units (now, Units (Capital)) set forth opposite such Effective Date Contributing Partner’s name on Exhibit A.

(c) The Partnership used the funds contributed pursuant to Section 5.01(b) (i) to redeem a number of Pre-Effective Date Units (Capital) from each holder of Pre-Effective Date Units (Capital) equal to the number of Units (Capital) issued to the Effective Date Contributing Partners pursuant to Section 5.01(b), in the case of each holder of Pre-Effective Date Units (Capital), in the numbers and for the amount set forth opposite the name of such holder on Exhibit B, and (ii) for general business purposes. The total number of Pre-Effective Date Units (Capital) redeemed from all holders of Pre-Effective Date Units (Capital) pursuant to this Section 5.01(c) shall not exceed that number of Pre-Effective Date Units (Capital) representing forty-nine percent (49%) of the Fair Market Value of the Pre-Effective Date Units (Capital) owned by such holders before the redemption.

(d) For federal income tax purposes, the Partnership and the Partners agree to report the transactions described in Sections 5.01(b) and 5.01(c), taken together, as a direct sale of Units (Capital) by each holder of Pre-Effective Date Units (Capital) to the Effective Date Contributing Partners for a purchase price equal to the dollar amount of the distribution made pursuant to Section 5.01(c); provided that, notwithstanding the foregoing and for the avoidance of doubt, for purposes of determining the amounts distributable to the Effective Date Contributing Partners pursuant to Section 7.01(a) and 7.01(b) with respect to the Units (Capital) issued pursuant to Section 5.01(b), the Unreturned Capital Contribution with respect to each such Unit (Capital) as of the Effective Date shall be equal to the amount per Unit (Capital) contributed by the Effective Date Contributing Partners pursuant to Section 5.01(b).

31

Section 5.02 Further Capital Contributions

(a) Except as otherwise provided herein, each Units (Capital) Limited Partner shall make additional Capital Contributions from time to time in an amount not to exceed its Remaining Units (Capital) Commitment Amount in proportion to its Units (Capital) Commitment Ratio, in each case, in amounts and at such times as shall be determined by the Board of Directors. Subject to Section 5.02(c), upon receipt of such additional Capital Contributions, the Partnership shall issue to each contributing Units (Capital) Limited Partner additional Units (Capital) at a price of $1.00 per Unit in the amount of such Capital Contribution.

(b) The Units (Capital) Limited Partners shall have ten (10) days from the issuance of a capital call pursuant to Section 5.02(a) and corresponding written notice to such Units (Capital) Limited Partners to make the Capital Contribution.

(c) In the event that (i) a Units (Capital) Limited Partner fails to make a Capital Contribution called for by the Board of Directors pursuant to Section 5.02(a) as required by Section 5.02(b), and the amount of such Capital Contribution with respect to such Units (Capital) Limited Partner is equal to or greater than $500,000, then the number of Units (Capital) issued in connection with such capital call to each Units (Capital) Limited Partner who makes its required Capital Contribution shall be determined by an Independent Advisor selected by the Board of Directors, based on the Fair Market Value of a Unit (Capital) determined as of the date of such capital call (in lieu of $1.00 per Unit), or (ii) a Units (Capital) Limited Partner fails to make a Capital Contribution called for by the Board of Directors pursuant to Section 5.02(a) as required by Section 5.02(b) when such Capital Contribution has been called in order to avoid a default under the ▇▇▇▇▇▇▇ Facility (a “Facility Default Capital Call”), and the amount of such Capital Contribution with respect to such Units (Capital) Limited Partner is equal to or greater than $500,000, then the number of Units (Capital) issued in connection with such capital call to each Units (Capital) Limited Partner who makes its required Capital Contribution shall be determined by an Independent Advisor selected by the Board of Directors, based on three (3) times the Fair Market Value of a Unit (Capital) determined as of the date of such capital call (in lieu of $1.00 per Unit (Capital)) (each of (i) and (ii) a “Dilution Event”).

(d) Following a Dilution Event, (i) in connection with any subsequent capital call by the Board of Directors pursuant to Section 5.02(a), the number of Units (Capital) issued to each Units (Capital) Limited Partner who makes its required Capital Contribution shall be determined by an Independent Advisor selected by the Board of Directors, based on the Fair Market Value of a Unit (Capital) determined as of the date of such capital call and (ii) each such subsequent capital call by the Board of Directors pursuant to Section 5.02(a) shall specify the required Capital Contribution of each Units (Capital) Limited Partner and upon funding, the Board of Directors shall issue each Units (Capital) Limited Partner who made its required Capital Contribution Units (Capital) valued at an amount equal to the Fair Market Value of Units (Capital) as most recently determined prior to such capital call by an Independent Advisor, and such issuances shall be subject to retroactive adjustment in accordance with Section 11.09(c) based on a final determination of the current Fair Market Value of such Units (Capital) by an Independent Advisor.

32

(e) Notwithstanding the provisions of Section 5.02(a), (i) Units (Capital) Limited Partners shall not be obligated to make any Capital Contributions to the extent that such Capital Contributions and all prior Capital Contributions made by such Units (Capital) Limited Partner would exceed their respective Units (Capital) Commitment Amounts, (ii) the aggregate Units (Capital) Commitment Amounts of Riverstone and Pattern Energy shall not collectively exceed $1.2 billion, and (iii) if a Units (Capital) Limited Partner who is an Employee on the Effective Date ceases to be an Employee for any reason, such Units (Capital) Limited Partner’s rights and obligations to make Capital Contributions shall immediately cease, and such Partner and his or her successors and assigns shall have no further obligation to make Capital Contributions to the Partnership.

Section 5.03 PEG 1 Option

(a) At any time following the first anniversary of the Effective Date, but before the fifth anniversary of the Effective Date, the Partnership shall have the option, but not the obligation, to (i) redeem any or all of the Pre-Effective Date Units (Capital) held by each of the Initial Limited Partner and the PEG 1 Limited Partners as of such date for the Fair Market Value of such Units (Capital) as of such date or (ii) cause a direct sale of all of the Pre-Effective Date Units (Capital) to the Effective Date Contributing Partners on the same economic terms as would apply to any such redemption. In the event of clause (ii) above, each of the Initial Limited Partner and the PEG 1 Limited Partners agrees to use their reasonable best efforts to cooperate with the Partnership to effect such transaction.

(b) In the event the option is exercised, the Board of Directors, in consultation with the Company’s tax advisors, will determine at the time the option is exercised the manner in which the exercise of the option will be reported for U.S. federal income tax purposes; provided that, the Units (Capital) Limited Partners and Units (Profits Interest) Limited Partners acknowledge and agree that (i) in the event any redemption transaction described in clause (i) of Section 5.03(a) is funded by Capital Contributions from Effective Date Contributing Partners, for purposes of determining the amounts distributable to the Effective Date Contributing Holders pursuant to Section 7.01(a) and 7.01(b) with respect to Units (Capital) issued by the Partnership in exchange for such Capital Contributions, the Unreturned Capital Contribution with respect to each such Unit (Capital) as of the date of issuance shall be equal to the amount contributed in respect of such Unit (Capital) and the Units (Capital) Preference Amount with respect to each such Unit (Capital) shall be determined based on the amount contributed in exchange for such Unit (Capital) and shall accrue from the issuance date, regardless of whether the Board of Directors determines that the redemption should be treated as a direct sale by the PEG 1 Limited Partners of the redeemed Units (Capital) to such Effective Date Contributing Partners for U.S. federal income tax purposes and (ii) in the event of a direct sale described in clause (ii) of Section 5.03(a), for purposes of determining the amounts distributable to the Effective Date Contributing Holders pursuant to Section 7.01(a) and 7.01(b) with respect to the purchased Units (Capital), the Unreturned Capital Contribution with respect to each such Unit (Capital) shall be equal to the purchase price paid for such Unit (Capital) and the Units (Capital) Preference Amount with respect to each such Unit (Capital) shall be determined based on the purchase price paid for such Unit (Capital) and shall accrue from the date of sale. The Units (Capital) Limited Partners and Units (Profits Interest) Limited Partners agree to amend this Agreement to the extent necessary to give effect to this Section 5.03(b) in a manner that is tax efficient, including in a manner that minimizes the likelihood that any Partner in the Partnership recognizes income as a result of implementing this Section 5.03(b).

33

Section 5.04 Withdrawal of Capital

No Partner shall have the right to withdraw any capital from the Partnership; provided, however, that the Board of Directors may determine to distribute capital to the Partners from time to time in accordance with the terms hereof.

Section 5.05 Alternative Sources of Capital

(a) Prior to making any capital calls pursuant to the terms of this Agreement, the Board of Directors shall, in good-faith, consider alternative or lower-cost sources of funding in lieu of making a capital call.

(b) In furtherance of the foregoing, following the Effective Date, in the event Pattern Energy is unable to fund its required Capital Contribution in cash, the Board of Directors may, in its sole discretion (but in no event is obligated to), permit Pattern Energy to borrow from the Partnership, from time to time, a Contribution Loan to fund a required Capital Contribution pursuant to Section 5.02, in which case Pattern Energy will cooperate with the Partnership in good faith to execute and deliver such documents or instruments reasonably required to effect such Contribution Loan on market terms as reasonably determined by Pattern Energy and the Board of Directors and otherwise on the terms set forth in this Section 5.05(b). Each Contribution Loan shall be full recourse to Pattern Energy. At the time any Contribution Loan is made to Pattern Energy, (i) the original principal amount of such Contribution Loan shall not exceed the amount of the additional Capital Contribution then required to be made by Pattern Energy pursuant to Section 5.02(a), (ii) the aggregate principal amount of all Contribution Loans between Pattern Energy and the Partnership outstanding as of such date shall not exceed $60 million, (iii) Pattern Energy shall immediately contribute the proceeds of such Contribution Loan to the Partnership as an additional Capital Contribution pursuant to Section 5.02(a), and (iv) Pattern Energy shall agree to repay the amount borrowed under such Contribution Loan in full within 365 days following the date of such Contribution Loan. All distributions payable to Pattern Energy pursuant to Section 7.01 of this Agreement shall be withheld and applied against the outstanding balance of any unpaid principal or interest amount attributable to any Contribution Loan that has not been fully repaid at the time such distribution becomes due and payable to Pattern Energy, regardless of the repayment terms of such Contribution Loan, but shall not be deemed to be an additional Capital Contribution by Pattern Energy.

Section 5.06 Capital Accounts

(a) A separate capital account (a “Capital Account”) will be maintained on the Partnership’s books and records for each Partner. Each Partner’s Capital Account will be increased by: (i) the amount of money contributed by such Partner to the Partnership; (ii) the initial Book Value of property contributed by such Partner to the Partnership (net of liabilities secured by such contributed property that the Partnership is considered to assume or take subject to under Section 752 of the Code); and (iii) allocations to such Partner of Profits and items of income or gain pursuant to the Regulatory Allocations. Each Partner’s Capital Account will be decreased by: (A)

the amount of money distributed to such Partner by the Partnership; (B) the Fair Market Value of property distributed to such Partner by the Partnership (net of liabilities secured by such distributed property that such Partner is considered to assume or take subject to under Section 752 of the Code); and (C) allocations to the account of such Partner of Losses and items of loss or deduction pursuant to the Regulatory Allocations.

(b) In the event of a Transfer of Units made in accordance with this Agreement, the Capital Account of the Transferor shall become the Capital Account of the Transferee to the extent it relates to the Transferred Units in accordance with Treasury Regulation Section 1.704-l(b)(2)(iv).

(c) The manner in which Capital Accounts are to be maintained pursuant to this Section 5.06 is intended to comply with the requirements of Section 704(b) of the Code and the Treasury Regulations promulgated thereunder. If, in the opinion of the Partnership’s legal counsel, the manner in which Capital Accounts are to be maintained pursuant to the preceding provisions of this Section 5.06 should be modified in order to comply with Section 704(b) of the Code and the Treasury Regulations thereunder, then notwithstanding anything to the contrary contained in the preceding provisions of this Section 5.06, the method in which Capital Accounts are maintained shall be so modified; provided, however, that any change in the manner of maintaining Capital Accounts shall not materially alter the economic agreement and relative economic benefits between or among the Partners.

(d) Except as otherwise required in the Act, no Partner shall have any liability to restore all or any portion of a deficit balance in such Partner’s Capital Account.

ARTICLE VI

ALLOCATIONS

Section 6.01 Allocations of Profits and Losses

After giving effect to the Regulatory Allocations, and subject to Section 14.03(b) of this Agreement, Profits and Losses for each Fiscal Period shall be allocated among the Partners for such Fiscal Period, in such a manner as shall cause the Capital Accounts of each Partner (as adjusted to reflect all Regulatory Allocations and all distributions through the end of such Fiscal Period) to equal, as nearly as possible, (a) the amount such Partner would receive if all assets of the Partnership on hand at the end of such Fiscal Period were sold for cash equal to their Book Values, all liabilities of the Partnership were satisfied in cash in accordance with their terms (limited in the case of non-recourse liabilities to the Book Value of the property securing such liabilities), all unvested Units (Profits Interest) became vested, and all remaining or resulting cash (including any Retained Distributions) were distributed to the Partners under Section 7.01 of this Agreement minus (b) such Partner’s share of Minimum Gain and Partner Nonrecourse Debt Minimum Gain, computed immediately prior to the hypothetical sale of assets.

35

Section 6.02 Regulatory Allocations

The following allocations shall be made in the following order:

(a) Nonrecourse Deductions shall be allocated 85% to the holders of Units (Capital) pro rata in proportion to their respective Unit (Capital) Sharing Percentages and 15% to the holders of Units (Profits Interest) pro rata in proportion to their respective Unit (Profits Interest) Sharing Percentages.

(b) Partner Nonrecourse Deductions attributable to Partner Nonrecourse Debt shall be allocated to the Partners bearing the Economic Risk of Loss for such Partner Nonrecourse Debt as determined under Treasury Regulation Section 1.704-2(b)(4). If more than one Partner bears the Economic Risk of Loss for such Partner Nonrecourse Debt, the Partner Nonrecourse Deductions attributable to such Partner Nonrecourse Debt shall be allocated among the Partners according to the ratio in which they bear the Economic Risk of Loss. This Section 6.02(b) is intended to comply with the provisions of Treasury Regulation Section 1.704-2(i) and shall be interpreted consistently therewith.

(c) Notwithstanding any other provision hereof to the contrary, if there is a net decrease in Minimum Gain for a taxable year (or if there was a net decrease in Minimum Gain for a prior taxable year and the Partnership did not have sufficient amounts of income and gain during prior years to allocate among the Partners under this Section 6.02(c)), items of income and gain shall be allocated to each Partner in an amount equal to such Partner’s share of the net decrease in such Minimum Gain (as determined pursuant to Treasury Regulation Section 1.704-2(g)(2)). This Section 6.02(c) is intended to constitute a minimum gain chargeback under Treasury Regulation Section 1.704-2(f) and shall be interpreted consistently therewith.

(d) Notwithstanding any provision hereof to the contrary except Section 6.02(c) of this Agreement (dealing with Minimum Gain), if there is a net decrease in Partner Nonrecourse Debt Minimum Gain for a taxable year (or if there was a net decrease in Partner Nonrecourse Debt Minimum Gain for a prior taxable year and the Partnership did not have sufficient amounts of income and gain during prior years to allocate among the Partners under this Section 6.02(d), items of income and gain shall be allocated to each Partner in an amount equal to such Partner’s share of the net decrease in Partner Nonrecourse Debt Minimum Gain (as determined pursuant to Treasury Regulation Section 1.704-2(i)(4)). This Section 6.02(d) is intended to constitute a partner nonrecourse debt minimum gain chargeback under Treasury Regulation Section 1.704-2(i)(4) and shall be interpreted consistently therewith.

(e) Notwithstanding any provision hereof to the contrary except Section 6.02(a) and Section 6.02(b), no Losses shall be allocated to any Limited Partner to the extent that such allocation would cause such Limited Partner to have a deficit balance in its Adjusted Capital Account (or increase any existing deficit balance in its Adjusted Capital Account) at the end of such Fiscal Period. All Losses in excess of the limitation set forth in this Section 6.02(e) shall be allocated to the Partners who do not have a deficit balance in their Adjusted Capital Accounts in proportion to their relative positive Adjusted Capital Accounts but only to the extent that such Losses do not cause any such Partner to have a deficit in its Adjusted Capital Account.

(f) Notwithstanding any provision hereof to the contrary except Section 6.02(c), Section 6.02(d) and Section 6.02(e) of this Agreement, a Partner who unexpectedly receives an adjustment, allocation or distribution described in Treasury Regulation Section 1.704-1(b)(2)(ii)(d)(4), (5) or (6) shall be allocated items of income and gain (consisting of a pro rata

36

portion of each item of income, including gross income, and gain for the taxable year) in an amount and manner sufficient to eliminate any deficit balance in such Partner’s Adjusted Capital Account as quickly as possible; provided that, an allocation pursuant to this Section 6.02(f) shall be made only if and to the extent that such Partner would have deficit Adjusted Capital Account balance after all other allocations provided for in this Article VI have been tentatively made as if this Section 6.02(f) were not in this Agreement. This Section 6.02(f) is intended to constitute a qualified income offset under Treasury Regulation Section 1.704-1(b)(2)(ii)(d) and shall be interpreted consistently therewith.

(g) In the event that any Partner has a deficit balance in its Capital Account at the end of any taxable year in excess of the sum of (A) the amount such Partner is required to restore pursuant to tax 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 allocated items of Partnership gross income, and gain in the amount of such deficit as quickly as possible; provided that an allocation pursuant to this Section 6.02(g) shall be made only if and to the extent that such Partner would have a deficit balance in its Capital Account after all other allocations provided for in this Article VI have been tentatively made as if Section 6.02(f) and this Section 6.02(g) were not in this Agreement.

(h) To the extent an adjustment to the adjusted tax basis of any Partnership properties pursuant to Code Section 734(b) or Code Section 743(b) is required pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(m)(2) or 1.704-1(b)(2)(iv)(m)(4) to be taken into account in determining Capital Accounts as the result of a distribution to any Partner in complete liquidation of such Partner’s Units, the amount of such adjustment to 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) and such gain or loss shall be allocated to the Partners in accordance with Treasury Regulation Section 1.704-1(b)(2)(iv)(m)(2) if such Section applies, or to the Partner to whom such distribution was made if Treasury Regulation Section 1.704-1(b)(2)(iv)(m)(4) applies.

(i) If any Units (Profits Interest) held by any holder of Units (Profits Interest) are forfeited or redeemed by the Partnership, such holder shall be allocated items of loss and deduction in the year of such forfeiture or redemption in an amount equal to the portion of such holder’s Capital Account attributable to such forfeited Units reduced, but not below zero, by the amount of any redemption price paid by the Partnership for such Units.

(j) If, as a result of an exercise of a noncompensatory warrant or option to acquire an interest in the Partnership, a Capital Account reallocation is required under Treasury Regulation Section 1.704-1(b)(2)(iv)(s)(3), the Partnership shall make corrective allocations pursuant to Treasury Regulation Section 1.704-1(b)(4)(x).

Section 6.03 Income Tax Allocations

(a) All items of income, gain, loss and deduction for federal income tax purposes shall be allocated in the same manner as the corresponding item of Profits and Losses is allocated, except as otherwise provided in this Section 6.03.

37

(b) In accordance with Code Section 704(c) and the applicable Treasury Regulations thereunder, income, gain, loss, and deduction with respect to any property contributed to the Partnership shall, solely for tax purposes, be allocated among the Partners so as to take account of any variation between the adjusted basis of such property to the Partnership for Federal income tax purposes and its initial Book Value. In the event the Book Value of any property is adjusted pursuant to clause (b) or (d) of the definition of Book Value, subsequent allocations of income, gain, loss, and deduction with respect to such property shall take account of any variation between the adjusted basis of such property for Federal income tax purposes and its Book Value in the same manner as under Code Section 704(c) and the applicable Regulations thereunder. For purposes of the allocations pursuant to this Section 6.03(b), the Partnership shall elect the remedial allocation method described in Treasury Regulation Section 1.704-3(d) or such other allocation method as is determined by the Board of Directors.

(c) Any (i) recapture of depreciation or any other item of deduction shall be allocated, in accordance with Treasury Regulations Sections 1.1245-1(e) and 1.1254-5, to the Partners who received the benefit of such deductions (taking into account the effect of remedial allocations), and (ii) recapture of any income tax credits shall be allocated to the Partners in accordance with Treasury Regulation Sections 1.704-1(b)(4)(ii) and 1.704-1(b)(4)(vii).

(d) Tax credits of the Partnership shall be allocated among the Partners as provided in Treasury Regulation Sections 1.704-1(b)(4)(ii) and 1.704-1(b)(4)(viii).

(e) Allocations pursuant to this Section 6.03 are solely for purposes of federal, state, and local taxes and shall not affect, or in any way be taken into account in computing, any Partner’s Capital Account (except as provided in Treasury Regulation Section 1.704-1(b)(2)(iv)(j)) or share of Profits, Losses, other items or distributions pursuant to any provision of this Agreement.

Section 6.04 Other Allocation Rules

(a) All items of income, gain, loss, deduction and credit allocable to an interest in the Partnership that may have been Transferred shall be allocated between the Transferor and the Transferee based on the portion of the Fiscal Year during which each was recognized as the owner of such interest, without regard to the results of Partnership operations during any particular portion of that year and without regard to whether cash distributions were made to the Transferor or the Transferee during that year; provided, however, that this allocation must be made in accordance with a method permissible under Code Section 706 and the Treasury Regulations thereunder.

(b) The Partners’ proportionate shares of the “excess nonrecourse liabilities” of the Partnership, within the meaning of Treasury Regulation Section 1.752-3(a)(3), shall be allocated 85% to the holders of Units (Capital) and 15% to the holders of Units (Profits Interest), and among each of the Units (Capital) Limited Partners and the Units (Profits Interest) Limited Partners in accordance with each such Partner’s respective Unit (Capital) Sharing Percentage or the Unit (Profits Interest) Sharing Percentage, as applicable.

ARTICLE VII

DISTRIBUTIONS

Section 7.01 Distributions

Except as set forth in Sections 5.01(c) and 5.03, and subject to Section 7.03, Section 7.05, and Section 14.03 of this Agreement, all Distributable Property of the Partnership shall be distributed at such time or times (if any) as the Board of Directors determines in its sole discretion to the Partners in the following order and priority:

(a) First: 100% to the Units (Capital) Limited Partners in proportion to their respective Unreturned Capital Contributions until the Unreturned Capital Contributions have been reduced to zero (0);

(b) Second: 100% to the Units (Capital) Limited Partners in proportion to their respective Unpaid Units (Capital) Preference Amounts until the Unpaid Units (Capital) Preference Amount of each Units (Capital) Limited Partner has been reduced to zero (0);

(c) Third: (i) 50% to the Units (Capital) Limited Partners in proportion to their respective Unit (Capital) Sharing Percentages and (ii) 50% to the Units (Profits Interest) Limited Partners in proportion to their respective Unit (Profits Interest) Sharing Percentages, until the Units (Profits Interest) Payout occurs; and

(d) Thereafter: 85% to the Units (Capital) Limited Partners in proportion to their respective Unit (Capital) Sharing Percentages and 15% to the Units (Profits Interest) Limited Partners in proportion to their respective Unit (Profits Interest) Sharing Percentages.

(e) In applying Section 7.01(c) and Section 7.01(d) of this Agreement, if any tranche of Units (Profits Interest) have been issued with a Threshold Amount greater than zero, a holder of such tranche of Units (Profits Interest) will not be entitled to receive distributions under this Section 7.01 until the aggregate distributions made following the issuance of such tranche of Units (Profits Interest) to the holders of the Units (Profits Interest) of each previously issued tranche of Units (Profits Interest) shall be equal to the Threshold Amount designated for such tranche of Units (Profits Interest). For example, prior to the holders of Units (Profits Interest)-4 receiving distributions under this Section 7.01, the holders of all Units (Profits Interest)-1, Units (Profits Interest)-2, and Units (Profits Interest)-3 must receive distributions that cause the Threshold Amount to be attained for the Units (Profits Interest)-4. Any distribution that otherwise would have been made to a tranche of Units (Profits Interest) with a Threshold Amount but for this subsection shall be treated as additional Distributable Property and distributed solely to the tranche of Units (Profits Interest) then entitled to receive distributions.

(f) Any distributions (except tax distributions pursuant to Section 7.03 of this Agreement) with respect to Units (Profits Interest) of any tranche that have not “vested” in accordance with the provisions of Section 11.08(b) of this Agreement shall be retained by the Partnership in a separate bank account until “vesting” occurs (the “Retained Distributions”). Retained Distributions shall be promptly distributed by the Partnership upon vesting of the relevant Units (Profits Interest). Retained Distributions that are in respect of unvested Units (Profits

39

Interest) that are forfeited to the Partnership pursuant to Section 11.08(c) of this Agreement shall be reallocated among the remaining outstanding Units (Profits Interest) pro rata in proportion to their respective Unit (Profits Interest) Sharing Percentages (as adjusted to take into account any Threshold Amount applicable to Units (Profits Interest)).

Section 7.02 Distributions in Kind

No Partner has any right to demand or receive a distribution from the Partnership in any form other than cash, and any distribution from the Partnership in any form other than cash or Marketable Securities must be approved by the Units (Capital) Majority and the Units (Profits Interest) Majority. Any non-cash distribution from the Partnership must also comply with the provisions of Section 11.13.

Section 7.03 Tax Distributions

(a) On each Tax Distribution Date, the Partnership shall, subject to the availability of Distributable Property, and prior to making distributions pursuant to Section 7.01, if any, distribute to each Partner in cash an amount equal to such Partner’s Assumed Tax Liability, if any, as of such date. If on a Tax Distribution Date there are not sufficient funds on hand to distribute to each Partner the full amount of such Partner’s Assumed Tax Liability, distributions pursuant to this Section 7.03 shall be made to the Partners to the extent of the available funds in proportion to each Partner’s Assumed Tax Liability, and the Partnership shall make future distributions as soon as funds become available to pay the remaining portion of such Partner’s Assumed Tax Liability. Notwithstanding the foregoing and for the avoidance of doubt, the Partners agree that the Partnership shall not be required to make distributions to a Partner pursuant to this Section 7.03 to the extent that such Partner realizes income in connection with the issuance or Transfer of Units (Profits Interest) to such Partner, the forfeiture of Units (Profits Interest) by such Partner or another Partner or the repurchase of Units (Profits Interest) from such Partner or another Partner in accordance with this Agreement.

(b) Any amounts distributed to a Partner pursuant to this Section 7.03 shall be treated as an advanced distribution of, and shall reduce by a like amount the next amounts otherwise distributable to, such Partner pursuant to Section 7.01 or Section 14.03(b) of this Agreement, as applicable. Amounts distributed to a Partner pursuant to this Section 7.03 that are treated as advanced distributions against amounts otherwise distributable shall be taken into account in determining when a Units (Capital) Payout or Units (Profits Interest) Payout occurs.

Section 7.04 Redemption/Repurchase of Units

In the event the Partnership has repurchased Units (Capital) or Units (Profits Interest) pursuant to Section 11.08(c) or otherwise (excluding any redemption or repurchase pursuant to Section 5.03), any amount paid to a holder of Units (Capital) in connection with such repurchase of Units (Capital) shall be treated as an advance distribution to the holders of the remaining Units (Capital) pursuant to Section 7.01 or Section 14.03, and any amount paid to a holder of Units (Profits Interest) in connection with such a repurchase of Units (Profits Interest) shall be treated as an advance distribution to the holders of the remaining Units (Profits Interest) pursuant to Section 7.01 or Section 14.03. Any amount treated as an advance distribution shall first, and solely for

40

computational purposes, be added to the next aggregate amounts distributable to holders of Units (Capital) and Units (Profits Interest), and then, after application of the distribution provisions of Section 7.01, reduce the amounts otherwise distributable to the holders of the remaining Units (Capital) or Units (Profits Interest), as applicable, by a like amount.

Section 7.05 Proceeds from Projects

The Board of Directors will use good faith efforts to distribute proceeds received from the sale or divestment, in whole or in part, of any development, construction or operating project of the Partnership or any of its Subsidiaries within thirty (30) days of receipt of such proceeds, provided, that the Board of Directors has determined, on the basis of a cash flow forecast provided by the Development Leadership Team to the Board of Directors on or about the date that such sale or divestment is consummated, that the Partnership has sufficient cash and property on hand to meet any liabilities or fund any proposed expenditures of the Partnership which are accrued or reasonably foreseeable within twelve (12) months following such date. In the event that a majority of the Board of Directors disagrees with such forecast, the Board of Directors may instead use the applicable twelve-month period of any Annual Budget.

Section 7.06 Withholding

(a) The Partnership may withhold distributions or portions thereof if it is required to do so by any applicable rule, regulation or law, and each Partner hereby authorizes the Partnership to withhold from and pay on behalf of or with respect to such Partner any amount of U.S. federal, state, local or foreign taxes that the Board of Directors determines that the Partnership is required to withhold and pay with respect to any amount distributable or allocable to such Partner pursuant to this Agreement and to pay any tax imposed on the Partnership (including where the amount of such tax is determined by reference to the status of a Partner (or its beneficial owners)).

(b) Except with respect to amounts that a Partner contributes to the Partnership upon the request of the Board of Directors, any amounts withheld pursuant to this Section 7.06 or paid pursuant to this Section where the amount of such tax is determined by reference to the status of a Partner (or its beneficial owners) shall be treated as having been distributed to such Partner for all purposes of this Agreement at the time such withholding or payment is made. To the extent that the cumulative amount of such withholding or payment for any period exceeds the distributions to which such Partner is entitled for such period, the amount of such excess shall be considered a loan from the Partnership to such Partner, with interest accruing at an interest rate determined by the Board of Directors or at the request of the Board of Directors, the amount of such excess shall be promptly paid to the Partnership by the Partner on whose behalf such withholding or payment is required to be made, provided that any such payment shall not be treated as a Capital Contribution and shall not reduce the amount that a Partner is otherwise obligated to contribute to the Partnership. Any income from any deemed loan shall not be allocated to or distributed to the Partner requiring such loan. Any such loan shall be satisfied out of distributions to which such Partner would otherwise be subsequently entitled until such time as the Board of Directors requests that the Partner pay such amount to the Partnership. Each Partner hereby unconditionally and irrevocably grants to the Partnership a security interest in such Partner’s Units to secure such Partner’s obligation to pay to the Partnership any amounts required to be paid pursuant to this Section 7.06. Each Partner shall take such actions as the Partnership may request in order to perfect or enforce the security interest created hereunder.

41

(c) Each Partner hereby agrees to indemnify and hold harmless the Partnership, the other Partners and the Board of Directors from and against any liability (including any liability for taxes, penalties, additions to tax or interest) with respect to income attributable to or distributions or other payments to such Partner (including pursuant to the Bipartisan Budget Act where amount of such tax is determined by reference to the status of a Partner (or its beneficial owners)). Upon the Partnership’s request, each Partner shall promptly provide to the Partnership a duly completed and executed IRS Form W-9 or the appropriate IRS Form W-8 and such other information as may be reasonably requested by the Partnership in order for it to accurately determine its withholding obligation, if any. Unless otherwise determined by the Board of Directors, notwithstanding anything to the contrary in this Agreement, any Partner who acquires its Units from a person who was a Partner of the Partnership at the time of the Transfer shall succeed to and be responsible for, and shall indemnify and hold harmless the Partnership from any amounts the transferor Partner would have been liable for under this Section 7.06 if the transferor had remained a Partner of the Partnership, provided, that for the avoidance of doubt, this sentence will not apply to the transactions described in Sections 5.01(c) or 5.01(d) of this Agreement.

ARTICLE VIII

MEETINGS OF PARTNERS

Section 8.01 Meetings

Annual meetings of Partners may, but need not, be held. The annual meeting of Partners may be held at such place and on such date as the Board of Directors may designate. Special meetings of the Partners, for any purpose or purposes, unless otherwise prescribed by statute, may be called by the Board of Directors, or any Partner or Partners who hold in the aggregate a Units (Capital) Majority.

Section 8.02 Place of Meetings

The Board of Directors may designate any place, either within or outside the State of Delaware, as the place of meeting for any meeting of the Partners. If no designation is made, or if a special meeting be otherwise called, the place of meeting shall be the principal executive office of the Partnership.

Section 8.03 Notice of Meetings

Written notice stating the place, day and hour of the meeting and the purpose or purposes for which the meeting is called shall be delivered not less than ten (10) nor more than fifty (50) days before the date of the meeting, either personally or by mail, by or at the direction of the Board of Directors or Person calling the meeting, to each Partner entitled to vote at such meeting.

42

Section 8.04 Record Date

For the purpose of determining Partners entitled to notice of or to vote at any meeting of Partners or any adjournment thereof, or Partners entitled to receive payment of any distribution, or in order to make a determination of Partners for any other purpose, the date on which notice of the meeting is mailed or the date on which the resolution declaring such distribution is adopted, as the case may be, shall be the record date for such determination of Partners.

Section 8.05 Quorum

Partners holding at least a Units (Capital) Majority represented in person or by proxy shall constitute a quorum at any meeting of Partners. In the absence of a quorum at any such meeting, a majority of the Units so represented may adjourn the meeting from time to time for a period not to exceed sixty (60) days without further notice. At such adjourned meeting at which a quorum shall be present or represented, any business may be transacted which might have been transacted at the meeting as originally noticed. The Partners present at a duly organized meeting may continue to transact business until adjournment, notwithstanding the withdrawal during such meeting of that number of Units whose absence would cause less than a quorum.

Section 8.06 Proxies

At all meetings of Partners, a Units (Capital) Limited Partner may vote in person or by proxy executed in writing by the Partner or by a duly authorized attorney in fact. Such proxy shall be filed with the Board of Directors before or at the time of the meeting. No proxy shall be valid after eleven (11) months from the date of its execution, unless otherwise provided in the proxy. A telegram, telex, cablegram, electronic mail or similar transmission by the Units (Capital) Limited Partner, or a photographic, facsimile or similar reproduction of an executed writing shall be effective for purposes of this Section 8.06. The chairman of the meeting shall decide all questions touching upon the qualification of voters, the validity of the proxies, and the acceptance or rejection of votes, unless an inspector or inspectors shall have been appointed by the chairman of the meeting, in which event such inspector or inspectors shall decide all such questions. A proxy shall be with full power of substitution and shall be revocable unless the proxy form conspicuously states that the proxy is irrevocable and the proxy is coupled with an interest. Should a proxy designate two (2) or more Persons to act as proxies, unless that instrument shall provide to the contrary, a majority or, if only two Persons are designated as proxies, then both, of such Persons present at any meeting at which their powers thereunder are to be exercised shall have and may exercise all the powers of voting or giving consents thereby conferred, or if only one be present, then such powers may be exercised by that one.

Section 8.07 Action by Partners Without a Meeting

Any action required or permitted to be taken at a meeting of Partners may be taken without a meeting if the action is evidenced by one or more written consents describing the action to be taken by the Partners that are signed by the Partners with the requisite authority whose consent is required to take the action under this Agreement. Action taken under this Section 8.07 is effective when the requisite number of Partners required to approve such action have signed the consent, unless the consent specifies a different effective date. The record date for determining Partners

43

entitled to take action without a meeting is the date the first Partner signs and delivers to the Partnership a written consent. A telegram, telex, cablegram, electronic mail or similar transmission by a Partner, or a photographic, photostatic, facsimile or similar reproduction of a writing signed by a Partner, shall be regarded as signed by the Partner for purposes of this Section 8.07.

Section 8.08 Waiver of Notice

When any notice is required to be given to any Partner, a waiver thereof in writing signed by the Person entitled to such notice, whether before, at, or after the time stated therein, shall be equivalent to the giving of such notice.

Section 8.09 Conduct of Meetings

All meetings of the Partners shall be presided over by the chairman of the meeting, who shall be a Director or Officer designated by the Board of Directors. The chairman of any meeting of Partners shall determine the order of business and the procedure at the meeting, including such regulation of the manner of voting and the conduct of discussion as seem to him in order.

Section 8.10 Limited Units (Profits Interest) Voting Rights

Units (Profits Interest) shall have no voting rights, except as set forth in Section 9.06 and Section 15.05 of this Agreement.

ARTICLE IX

MANAGEMENT OF THE PARTNERSHIP

Section 9.01 Management

(a) In order to enable the Board of Directors to manage the business and affairs of the Partnership, the General Partner hereby irrevocably delegates to the Board of Directors and, solely to the extent necessary to enable the Officers appointed by the Board of Directors pursuant to Section 9.03 of this Agreement to fulfill their duties under this Agreement, to the Officers all management powers over the business and affairs of the Partnership that it may now or hereafter possess under applicable law (other than its obligations as “Tax Matters Partner” or “Partnership Representative”, as applicable, under Section 4.03 of this Agreement) as permitted under Section 17-403(c) of the Act. The General Partner further agrees to take any and all action necessary and appropriate, in the sole discretion of the Board of Directors, to effect any duly authorized actions by the Board of Directors or any Officer, including executing or filing any agreements, instruments or certificates, delivering all documents, providing all information and taking or refraining from taking action as may be necessary or appropriate to achieve all the effective delegation of power described in this Section 9.01(a). Each of the Partners and Transferees and each Person who may acquire an interest in a Partnership Interest hereby approves, consents to, ratifies and confirms such delegation. The delegation by the General Partner to the Board of Directors of management powers over the business and affairs of the Partnership pursuant to the provisions of this Agreement shall not cause the General Partner to cease to be a general partner of the Partnership nor shall it cause the Board of Directors or any member thereof to be a general partner of the

44

Partnership or to have or be subject to the liabilities of a general partner of the Partnership. Except as provided in Section 4.03 of this Agreement relating to the General Partner’s duties as “Tax Matters Partner” and/or “Partnership Representative”, as applicable, (subject to the limitations set forth therein) and except as otherwise provided in this Agreement, the management of the Partnership shall be vested exclusively in the Board of Directors and, subject to the direction of the Board of Directors, the Officers. Neither the General Partner nor any of the Limited Partners in their capacities as such shall have any part in the management of the Partnership (except, with respect to the General Partner, as provided in Section 4.03 of this Agreement relating to its duties as “Tax Matters Partner” and/or “Partnership Representative” (subject to the limitations set forth therein), as applicable, and shall have no authority or right to act on behalf of the Partnership or deal with any third parties on behalf of the Partnership in connection with any matter, except as requested or authorized by the Board of Directors.

(b) To the fullest extent permitted by the Act, a person, in performing his or her duties and obligations as a Director under this Agreement, shall be entitled to act or omit to act at the direction of the Partners that designated such person to serve on the Board of Directors, considering only such factors, including the separate interests of the designating Partners, as such Director or Partners choose to consider, and any action of a Director or failure to act, taken or omitted in good faith reliance on the foregoing provision shall not, as between the Partnership and the other Partners, on the one hand, and the Director or Partners designating such Director, on the other hand, constitute a breach of any duty (including any fiduciary or other similar duty, to the extent that such exists under the Act or any other applicable law, rule or regulation) on the part of such Director or Partners of the Partnership or any other Director or Partner.

(c) Unless explicitly provided otherwise in this Agreement, the Board of Directors shall have the power, right and authority on behalf and in the name of the Partnership to carry out any and all of the objects and purposes of the Partnership and to perform all acts which the Board of Directors, in its sole discretion, may deem necessary or desirable, including, without limitation, the power to:

(i) negotiate, execute and perform, any contract, agreement or other instrument (including, without limitation, this Agreement) as the Board of Directors shall determine to be necessary or desirable to further the purposes of the Partnership;

(ii) open, maintain and close bank accounts and draw checks or other orders for the payment of moneys;

(iii) collect all sums due the Partnership and contest and exercise the Partnership’s right to collect all such sums;

(iv) to the extent that funds of the Partnership are available therefor, pay as they become due all debts, obligations and operating expenses of the Partnership;

(v) make any expenditures, lend or borrow money, assume, guarantee or contract for, indebtedness or other liabilities, make prepayments or extensions of debt, secure debt of the Partnership with Partnership assets;

45

(vi) acquire, hold, manage, own, sell, Transfer, convey, assign, exchange or otherwise dispose of any assets of the Partnership or cause any Subsidiaries of the Partnership to acquire, hold, manage, own, sell, Transfer, convey, assign, exchange or otherwise dispose of any assets of such Subsidiaries;

Riverstone may designate up to two (2) individuals and Pattern Energy may designate one (1) individual, to attend quarterly meetings of the Board of Directors as observers and receive written materials distributed in connection with such meetings; provided, however, that no such observer shall in any circumstance have any right to participate in any vote, consent or other action of the Board of Directors, the failure by any observer to attend a meeting shall in no way invalidate any actions taken at such meeting, and no observer shall count towards the quorum requirements described in Section 9.02(c).

(c) Votes per Director; Quorum; Required Vote for Board Action. Each Director shall have one (1) vote; provided, however, that any Riverstone Designee shall be entitled to cast more than one vote under the following circumstances: (i) if any of the Riverstone Designees are not present at such meeting, then the Riverstone Designee or Riverstone Designees present at the meeting shall be given an aggregate number of additional votes equal to the number of Riverstone Designees absent (and such absent Riverstone Designee or Riverstone Designees shall be deemed to have given a proxy to vote at such meeting to any other Riverstone Designee who is present at such meeting) or (ii) if there are any vacancies in the Riverstone Designees, then the remaining Riverstone Designee or Riverstone Designees shall be given an aggregate number of additional votes equal to the number of vacancies of the Riverstone Designees (for example, if the Riverstone Group has only designated one of its three Directors, then that one Riverstone Designee may cast a total of three votes on matters presented to the Board of Directors). Unless otherwise required by this Agreement, Directors having at least three votes, either present (in person or by teleconference) or represented by proxy, including at least one Riverstone Designee, and, to the extent required for any vote pursuant to Sections 9.05 or 9.07, at least one Management Designee, shall constitute a quorum for the transaction of business at a meeting of the Board of Directors.

Special meetings of the Board of Directors may be called by any Director or Directors having at least two votes on at least 24 hours personal, written, telegraphic, cable, wireless or electronic notice to each Director, which notice must include appropriate dial-in information to permit each Director to participate in such meeting by means of telephone conference. Such notice need not state the purpose or purposes of such meeting, except as may otherwise be required by the Act.

(g) Action Without a Meeting. Any action required or permitted to be taken at any meeting of the Board of Directors may be taken without a meeting if a consent in writing, setting forth the action so taken, shall be signed by the Directors whose votes would be required to take action at a meeting of the Board of Directors and such written consent shall be distributed to the entire Board of Directors at least twenty-four (24) hours prior to its effective time.

(h) Telephonic Conference Meeting. Subject to the requirement for notice of meetings, members of the Board of Directors may participate in a meeting by means of a conference telephone or similar communications equipment by means of which all persons participating in the meeting can hear each other, and participation in such a meeting shall constitute presence in person at such meeting, except where a person participates in the meeting for the express purpose of objecting to the transaction of any business on the ground that the meeting is not lawfully called or convened.

(i) Waiver of Notice Through Attendance. Attendance of a Director at any meeting of the Board of Directors (including by telephone) shall constitute a waiver of notice of such meeting, except where such Director attends the meeting for the express purpose of objecting to the transaction of any business on the ground that the meeting is not lawfully called or convened and notifies the other Directors at such meeting of such purpose.

(j) Reliance on Books, Reports and Records.

48

(l) Board Committees. The Board of Directors may, by resolution passed by a majority of the entire Board of Directors, designate one or more committees to exercise such delegated power and authority as the Board of Directors may from time to time determine, including with respect to matters otherwise apportioned to the Board of Directors. Any such committee shall consist of one or more of the Directors. For the avoidance of doubt, any such committee, to the extent allowed by law, shall not act in the capacity of the Board of Directors, but notwithstanding anything to the contrary herein shall have and may exercise all the powers and authority in the management of the business and affairs of the Partnership provided to such committee in the resolutions establishing such committee, provided that no committee designation shall limit the application of Section 9.05 (with respect to approvals by two-thirds of the Units (Capital)), Section 9.06 (with respect to approvals by Pattern Energy) or Section 9.07 (with respect to approvals by a Units (Profits Interest) Majority) except to the extent, if any, that such approval rights may be prospectively waived by the Person or Persons holding the applicable approval rights at the time of designation.

ARTICLE X

INDEMNIFICATION

Section 10.01 Power to Indemnify in Actions, Suits or Proceedings

Subject to Section 10.02 of this Agreement, to the fullest extent permitted by law, the Partnership shall indemnify, defend and hold harmless any Person (and such Person’s heirs, administrators and executors) who was or is a party or is threatened to be made a party to, or is otherwise involved in, any threatened, pending or completed action, suit or proceeding (brought in the right of the Partnership or otherwise), whether civil, criminal, administrative or investigative, and whether formal or informal, including appeals, by reason of the fact that he is or was a Partner, Officer or Director of the Partnership, or is or was serving at the request of the Partnership for any other enterprise (each such Person described herein, an “Indemnitee”), from and against any and all losses, claims, expenses (including attorneys’ fees), costs, liabilities, damages, judgments, fines and amounts paid in settlement actually and reasonably incurred by such Indemnitee, in connection with such action, suit or proceeding, including appeals; provided, that such Indemnitee shall not be indemnified by the Partnership hereunder to the extent that such Indemnitee’s conduct constituted fraud, willful or intentional misconduct or criminal wrongdoing or gross negligence. For the avoidance of doubt, any Units (Profits Interest) Limited Partner who shall serve as a member, officer, director, manager, agent or employee of any Subsidiary or any other enterprise shall be deemed to serve at the request of the Partnership. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that such Indemnitee’s actions were not in accordance with the previous standard. Any indemnification provided hereunder will be satisfied solely out of the assets of the Partnership, as an expense of the Partnership. No Partner will be subject to personal liability by reason of these indemnification provisions.

Without limiting the generality of the foregoing, to the extent that an Indemnitee has been successful on the merits or otherwise in defense of any such action, suit or proceeding, or in defense of any claim, issue or matter therein, he shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by him in connection therewith. An Indemnitee shall not be denied indemnification in whole or in part under this Article X because the Indemnitee had an interest in the transaction with respect to which indemnification applies if the transaction was otherwise permitted by the terms hereof.

Section 10.02 Expenses Payable in Advance

To the fullest extent permitted by law, expenses incurred by an Indemnitee in appearing at, participating in, defending or investigating a threatened or pending action, suit or proceeding shall be promptly paid by the Partnership in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such Indemnitee to repay such amount if it shall ultimately be determined that he is not entitled to be indemnified by the Partnership as authorized by this Article X.

54

Section 10.03 Unpaid Claims

If a claim for indemnification (following the final disposition of such action, suit or proceeding) or advancement of expenses under this Article X is not paid in full within thirty (30) days after a written claim therefor by an Indemnitee has been received by the Partnership, such Indemnitee may, without the consent of the Board of Directors, institute proceedings to recover the unpaid amount of such claim and, if successful in whole or in part, shall be entitled to be paid the expense of prosecuting such claim. In any such action the Partnership shall have the burden of proving that such Indemnitee is not entitled to the requested indemnification or advancement of expenses under this Agreement or applicable law.

Section 10.04 Nonexclusivity of Indemnification and Advancement of Expenses

The indemnification and advancement of expenses provided by or granted pursuant to this Article X shall not be deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any agreement, contract, vote of Partners or Board of Directors or pursuant to the direction (howsoever embodied) of any court of competent jurisdiction, arbitrator or otherwise, both as to action in his official capacity and as to action in another capacity while holding such office, it being the policy of the Partnership that indemnification of Indemnitees shall be made to the fullest extent permitted by applicable law. The provisions of this Article X shall not be deemed to preclude the indemnification of any Person who is not specified in Section 10.01 of this Agreement, but whom the Partnership has the power or obligation to indemnify under the provisions of the Act or otherwise.

Section 10.05 Survival of Indemnification and Advancement of Expenses; Third Party Beneficiaries

The obligations of the Partnership under this Article X create vested rights in the Indemnitees effective as of the date the Indemnitee first commences service for the Partnership, its Subsidiaries, and/or any other enterprise (as defined in Section 10.09). Indemnification and advancement of expenses provided by, or granted pursuant to, this Article X shall continue as to an Indemnitee who has ceased to be a Partner, Officer, Director or employee. The provisions of this Article X shall be deemed to be a contract between the Partnership and each Indemnitee. Except to the extent required by law, any amendment, modification or repeal of this Article X or any provision hereof that does not expand the rights of the Indemnitees (a) shall be prospective only and shall not in any way affect the Partnership’s liability to any such Indemnitee under this Article X, as in effect immediately prior to such amendment, modification, or repeal with respect to actions, suits, proceedings or claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such actions, suits, proceedings or claims may arise or be asserted and (b) shall not be effective unless the holders of a Units (Profits Interest) Majority approve such amendment, modification or repeal pursuant to Section 9.07. The provisions of this Article X are intended to be for the benefit of, and shall be enforceable by, each Indemnitee, and his or her heirs and legal representatives, (each of whom are intended third party beneficiaries) and shall be in addition to any other rights an Indemnitee may have under any contract, by law, or under any other arrangement.

55

Section 10.06 Limitation on Indemnification

Notwithstanding anything contained in this Article X to the contrary, except for proceedings to enforce rights to indemnification and advancement of expenses, the Partnership shall not be obligated to indemnify any Partner, Officer or Director in connection with a proceeding (or part thereof) initiated by such Person unless such proceeding (or part thereof) was authorized or consented to by the Board of Directors.

Section 10.07 Indemnification of Employees and Agents

The Partnership may, to the extent authorized from time to time by the Board of Directors, provide rights to indemnification and the advancement of expenses to employees and agents of the Partnership and its Subsidiaries similar to those conferred in this Article X to the Indemnitees.

Section 10.08 Severability

The provisions of this Article X are intended to comply with the Act. To the extent that any provision of this Article X authorizes or requires indemnification or the advancement of expenses contrary to the Act or the Certificate, the Partnership’s power to indemnify or advance expenses under such provision shall be limited to that permitted by the Act and the Certificate and any limitation required by the Act or the Certificate shall not affect the validity of any other provision of this Article X. If any provision of this Article X shall be or become invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained in this Article X shall not be affected thereby.

Section 10.09 Fiduciary Service

For purposes of this Article X, references to “other enterprise” shall include each Subsidiary of the Partnership, any employee benefit plan and any other entity (including a limited liability company, limited partnership or corporation), committee, association, joint venture, enterprise, trust or unincorporated operation that an Indemnitee is serving at the request of the Partnership; references to “fines” shall include any excise taxes assessed on a Person; and the Partnership shall be deemed to have requested, and references to “serving at the request of the Partnership” shall include, any service as a director, officer, employee, agent, trustee, fiduciary, consultant, administrator, representative, or delegate of or for the Partnership, any Subsidiary and/or any other enterprise, including any capacity with respect to an employee benefit plan, its participants, or beneficiaries.

Section 10.10 Exculpation

No Partner, Officer or Director of the Partnership will be liable to the Partnership or to any Partner for any act or failure to act, unless such Person’s action or failure to act constituted fraud, willful or intentional misconduct or criminal wrongdoing or gross negligence. The Partners, Officers and Directors of the Partnership will not be liable to the Partnership or to any Partner for such Person’s good faith reliance on the provisions of this Agreement. Except with respect to Section 9.05, Section 9.06 and Section 9.07, the Board of Directors may exercise any of the powers granted to it by this Agreement and perform its duties either directly or through its agents and it shall not be responsible for any misconduct or negligence on the part of any such agent appointed by it in good faith.

56

Section 10.11 Indemnitor of First Resort

As a result of agreements or obligations arising outside of this Agreement, it may be the case that certain of the Indemnitees (“Sponsor Indemnitees”) have certain rights to indemnification, advancement of expenses or insurance provided by (a) Riverstone or certain of its Affiliates (the “Riverstone Indemnitors”) or (b) the Initial Limited Partner, Pattern Energy or certain of their respective Affiliates (the “PEG Indemnitors”, and together with the Riverstone Indemnitors, the “Sponsor Indemnitors”). However, regardless of whether or not there are any such rights to indemnification, advancement of expenses or insurance provided by any Sponsor Indemnitor, (i) the Partnership is the indemnitor of first resort (i.e., the Partnership’s obligations to each Sponsor Indemnitee are primary and any obligation of the Riverstone Indemnitors or the PEG Indemnitors, as applicable, to advance expenses or to provide indemnification for the same expenses or liabilities incurred by any Sponsor Indemnitee are secondary) to the extent of the indemnification obligations of the Partnership hereunder, (ii) the Partnership shall be required to advance the full amount of expenses incurred by a Sponsor Indemnitee and shall be liable for the full amount of all expenses, judgments, penalties, fines and amounts paid in settlement to the extent legally permitted and as required by the terms of this Agreement (or any other agreement between the Partnership and the Sponsor Indemnitees) and (iii) to the extent of the indemnification obligations of the Partnership hereunder, the Partnership hereby irrevocably waives, relinquishes and releases each of the Sponsor Indemnitors from any and all claims against any of the Sponsor Indemnitors for contribution, subrogation or any other recovery of any kind in respect thereof. Regardless of any advancement or payment by the Sponsor Indemnitors on behalf of any Sponsor Indemnitee with respect to any claim for which a Sponsor Indemnitee has sought indemnification from the Partnership, to the extent of the indemnification obligations of the Partnership hereunder, (x) the foregoing shall not be affected and (y) the Riverstone Indemnitors or the PEG Indemnitors, as applicable, shall have a right of contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of recovery of such Sponsor Indemnitee against the Partnership.

Section 10.12 Insurance

The Partnership may purchase and maintain insurance on behalf of any one or more Indemnitees and other Persons against any liability that may be asserted against or expense that may be incurred by such Person in connection with the activities of the Partnership, its Subsidiaries or other enterprises as to which the Partnership has requested service, whether or not the Partnership would have the power to indemnify such Person against such liability hereunder. The Partnership shall maintain policies of directors’ and officers’ liability insurance for the Board of Directors and all Officers with respect to claims arising from facts or events that occurred on or after the Initial Closing Date, including in respect of the matters contemplated by this Agreement.

ARTICLE XI

TRANSFER OF UNITS

Section 11.01 Request for Sale of Partnership by a Units (Capital) Majority

(a) Subject to Section 11.13, a Units (Capital) Majority, at any time after the date of this Agreement, may give written notice to the Partnership and the Partners requiring a sale of the Partnership (an “Approved Sale”). An Approved Sale may be effected pursuant to a securities disposition (by unit sale, merger, consolidation or otherwise) or asset disposition, as determined by the Units (Capital) Majority in its sole discretion. Subject to the other provisions of this Section 11.01, each Partner hereby agrees to vote (to the extent any such vote is required) all of its Units in favor of an Approved Sale upon the written request of the Units (Capital) Majority. If the Approved Sale is structured as a (i) merger, consolidation or sale of assets, each Partner shall waive any dissenters’ rights, appraisal rights or similar rights in connection with such merger, consolidation or sale of assets or (ii) sale of Units, each Partner shall agree subject to the other provisions of this Section 11.01 to sell all of his, her or its Units or rights to acquire Units at the price and upon the payment terms approved by the Units (Capital) Majority. If the Units (Capital) Majority is subject to any indemnification holdback in the consideration paid to it for Units sold pursuant to this Section 11.01, any Units (Profits Interest) Limited Partner who sells any of its Units (Capital) or Units (Profits Interest) pursuant to the terms of this Section 11.01 shall be subject to the same indemnification holdback as the Units (Capital) Majority, in accordance with such Units (Profits Interest) Limited Partner’s proportional share of the Units sold. Each Partner shall take all necessary actions in connection with the consummation of the Approved Sale as reasonably requested by the Units (Capital) Majority; provided, that no Partner shall be required to make any representation other than as to its ownership of its Units and no Partner shall assume or incur any liability other than its pro rata share based on the Units sold of any such indemnification holdback.

(b) In any Approved Sale:

(i) the Units (Capital) and Units (Profits Interest) shall be converted into or entitled to receive, as applicable, a proportionate amount of the aggregate consideration to be paid by the acquiring party, with such proportions to be determined by applying Section 7.01 of this Agreement to a Distributable Property amount equal to the sum of (a) the cash included in such consideration plus (b) the Fair Market Value of any non-cash property included in such consideration;

(ii) each holder of Units (Capital) shall receive such holder’s proportionate share of the aggregate consideration to be allocated to Units (Capital) pursuant to Section 11.01(b)(i) of this Agreement based on the amount it is entitled to receive under Section 7.01; and

(iii) each holder of a tranche of Units (Profits Interest) shall receive such holder’s proportionate share of the aggregate consideration allocated to the tranches of Units (Profits Interest) pursuant to Section 11.01(b)(i) of this Agreement based on the amount it is entitled to receive under Section 7.01.

58

(c) If the Approved Sale is a transaction for which Rule 506 (or any similar rule then in effect) promulgated by the Securities and Exchange Commission may be available with respect to such transaction (including a merger, consolidation or other reorganization), the Partners (other than those qualifying as Accredited Investors) shall, at the request of a Units (Capital) Majority, appoint a purchaser representative (as such term is defined in Rule 501) reasonably acceptable to such Units (Capital) Majority. If any Partner appoints a purchaser representative, the Partnership will pay the fees of such purchaser representative. If the consideration consists of securities and in order to qualify for an exemption from the Securities Act such securities cannot be sold to non-Accredited Investors, then the non-Accredited Investors shall be entitled to receive, in lieu of such securities, an amount, in cash, equal to the Fair Market Value (as determined pursuant to Section 11.09) of the portion of the Units held by the non-Accredited Investors that would otherwise be exchanged in consideration for such securities.

(d) Partners shall bear their pro rata share (based upon the allocation set forth in Section 11.01(b)) of the costs of any sale of Units pursuant to an Approved Sale to the extent such costs are incurred for the benefit of all Partners; all such costs that are incurred for the benefit of all Partners to be paid by the Partnership if not netted from the sales proceeds or paid by the acquiring party. Notwithstanding anything herein to the contrary, for purposes of this Section 11.01(d), costs incurred by the Units (Capital) Limited Partners or Units (Profits Interest) Limited Partners in exercising reasonable efforts to take all actions in connection with the consummation of an Approved Sale in accordance with this Section 11.01(d) shall be deemed to be for the benefit of all Partners for purposes of this Section 11.01. Costs incurred by Partners on their own behalf will not be considered costs of the transaction hereunder.

Section 11.02 Conversion to a Corporation; Qualified Public Offering

(a) Subject to Section 11.13, the Board of Directors, with written Board Approval and the approval of a Units (Capital) Majority, may cause the conversion in connection with a Qualified Public Offering of the Partnership, or any portion thereof, into a corporation, including by (i) the Transfer of all of the assets of the Partnership, subject to the Partnership’s liabilities, or the Transfer of any portion of such assets and liabilities, to one or more corporations in exchange for shares of any such corporations and the subsequent distribution of such shares, at such time as the Board of Directors may determine, to the Partners, (ii) conversion of the Partnership into a corporation pursuant to Section 17-219 of the Act (or any successor section thereto), (iii) Transfer by each Partner of Units held by such Partner to one or more corporations in exchange for shares of any such corporations (including by merger of the Partnership into a corporation) (or, in the case of any single purpose entity treated as corporation for U.S. federal income tax purposes that holds a direct or indirect interest in Riverstone (a “Blocker Corporation”), at the request of Riverstone, merge the Blocker Corporation into the corporation resulting from the Qualified Public Offering of the Partnership in a tax-free reorganization or otherwise structure the Qualified Public Offering so that the Blocker Corporation is not subject to a corporate-level tax on the Qualified Public Offering or subsequent dividend payments or sales of stock), or (iv) by filing an election pursuant to Treasury Regulation Section 301.7701-3(c) (each of (i), (ii) and (iii), a “Reorganization”). The Partners shall take all actions reasonably requested by the Board of Directors in connection with the consummation of such Reorganization, including without limitation consenting to, voting for and waiving any dissenters rights, appraisal rights or similar rights and participating in any exchange or other transaction required in connection with such Reorganization. The Partnership

59

shall pay any and all reasonable organizational, legal and accounting expenses and filing fees incurred by the Partnership, the Units (Capital) Limited Partners and the Units (Profits Interest) Limited Partners in connection with such Reorganization; provided, that the Partnership shall only have to pay for one counsel to represent the interests of all of the Units (Profits Interest) Limited Partners and one counsel to represent the interests of all of the Units (Capital) Limited Partners.

(b) In connection with any Reorganization as described in Section 11.02(a) of this Agreement, the shares (which will be valued at their Fair Market Value immediately prior to the Qualified Public Offering) received will be distributed in accordance with Section 7.01 of this Agreement (as adjusted to take into account any Threshold Amount applicable to any tranche of Units (Profits Interest)).

(c) In connection with any Reorganization as described in Section 11.02(a) of this Agreement:

(i) the Units (Capital) and Units (Profits Interest) shall be converted into a proportionate amount of the common stock of the resulting corporation, with such proportion to be determined by applying Section 7.01 of this Agreement to the total number of shares of common stock to be distributed upon conversion (which shares will be valued based on the valuation immediately prior to the Qualified Public Offering, less underwriting discounts and commissions, if any, and expenses);

(ii) each holder of Units (Capital) shall receive such holder’s proportionate share of the aggregate number of shares to be allocated to Units (Capital) pursuant to Section 11.02(c)(i) of this Agreement based on the amount it is entitled to receive under Section 7.01; and

(iii) each holder of Units (Profits Interest) shall receive such holder’s proportionate share of the aggregate number of shares to be allocated to each tranche of the Units (Profits Interest) pursuant to Section 11.02(c)(i) of this Agreement based on the amount it is entitled to receive under Section 7.01, provided that all shares received with respect to unvested Units (Profits Interest) will be subject to the same vesting conditions as applied to such Units (Profits Interest).

If securities other than, or in addition to, common stock are issued to Unit holders by the resulting corporation in such Reorganization, each class or series of securities shall be allocated among the holders of Units as provided in this Section 11.02(c).

(d) In connection with any such Reorganization as described in Section 11.02(a) of this Agreement, the Units (Capital) and the Units (Profits Interest) shall be converted into the right to receive the same series or class of securities of the corporation (in the case of Reorganizations described in Section 11.02(a)) or the Partnership (in the case of Reorganizations described in Section 11.02(a)) and such securities shall be allocated among the Units (Capital) and Units (Profits Interest), and among the holders of Units (Capital) and Units (Profits Interest), in the same manner as shares of common stock are allocated in the event of a Reorganization under Section 11.02(a) of this Agreement as provided in Section 11.02(c) of this Agreement.

60

(e) In connection with any Reorganization as provided in Section 11.02(a) of this Agreement, (i) each holder of Units (Capital) and Units (Profits Interest) shall receive the same form of securities and the same amount of securities per Unit of such Units (Capital) and Units (Profits Interest), respectively, and, if any holders of Units (Capital) or Units (Profits Interest) are given an option as to the form and amount of securities to be received, each holder of the Units (Capital) or Units (Profits Interest), as applicable, shall be given the same option and (ii) each holder of Units agrees to the Transfer of its Units in accordance with the terms of conversion or exchange, as applicable, as provided by the Board of Directors. Each holder of Units further agrees that as of the effective date of such conversion or exchange any Unit outstanding thereafter that shall not have been tendered for conversion or exchange shall represent only the right to receive a certificate representing the number of shares of any such corporations as provided in the terms of such conversion or exchange.

(f) If the Board of Directors approves a Qualified Public Offering, the Partners shall take all necessary or desirable actions reasonably requested by the Partners in connection with the consummation of such Qualified Public Offering, including without limitation compliance with the requirements of all laws and regulatory bodies that are applicable or that have jurisdiction over such Qualified Public Offering. If such Qualified Public Offering is an underwritten offering:

(i) and the managing underwriters advise the Partnership in writing that in their opinion the Partnership’s capital structure would adversely affect the marketability of the offering, each Partner shall consent to and vote for a recapitalization, reorganization or exchange (each, a “Recapitalization”) of any class of the Partnership’s equity securities into securities that the managing underwriters and the Board of Directors find acceptable and shall take all necessary and desirable actions in connection with the consummation of such Recapitalization; provided that each holder of a class of Units shall receive the same type of security with the same value per Unit (other than differences based upon differences in the amount of yield accrued on such Units since their respective dates of issuance) and shall be subject to the same restrictions on lock-up and transferability unless otherwise agreed to by the Partners; and

(ii) if requested by the managing underwriters, each of the Partners shall execute customary lock-up agreements with respect to their Units and/or any securities received by them in any attendant Reorganization or Recapitalization.

(g) In connection with a Reorganization or Recapitalization associated with a Qualified Public Offering, any Units (Capital) Limited Partner that is a qualified institutional buyer (as defined in Rule 144A promulgated under the Securities Act) may elect to receive distributions with respect to its Units (Capital) in cash, in lieu of shares.

(h) The provisions of this Section 11.02 are not intended to and shall not in any way diminish the power and authority of the Board of Directors as set forth in Section 9.01 of this Agreement or any other provision of this Agreement.

61

Section 11.03 Demand Registration Rights

(a) General. If the Partnership (or successor entity) (for purposes of this Section 11.03 and Section 11.04, the “Public Entity”) shall receive from holder(s) of a Units (Capital) Majority after six (6) months after the Public Entity has closed a Qualified Public Offering, a written request that the Public Entity file a registration statement with respect to Registrable Securities (the sender(s) of such request or any similar request pursuant to this Section 11.03 and Section 11.04 shall be known as the “Initiating Holder(s)”), then the Public Entity shall, within thirty (30) days of the receipt thereof, give written notice of such request to all Holders, and subject to the limitations of this Section 11.03, use its best efforts to effect, as soon as practicable, the registration under the Securities Act of all Registrable Securities that the Holders request to be registered. The Public Entity shall not be obligated to take any action to effect any such registration:

(i) after it has effected three (3) such registrations pursuant to this Section 11.03, and such registrations have been declared or ordered effective;

(ii) within six (6) months of a registration pursuant to this Section 11.03 that has been declared or ordered effective;

(iii) during the period starting with the date sixty (60) days prior to its good faith estimate of the date of filing of, and ending on a date one hundred eighty (180) days after the effective date of, a Public Entity-initiated registration (other than a registration relating solely to the sale of securities to employees of the Public Entity pursuant to a stock option, stock purchase or similar plan or to a Rule 145 transaction), provided that the Public Entity is actively employing in good faith all reasonable efforts to cause such registration statement to become effective;

(iv) where the anticipated aggregate offering price, net of any underwriting discounts or commissions, is equal to or less than twenty-five million dollars ($25,000,000);

(v) if the Public Entity shall furnish to such Initiating Holder(s) a certificate signed by the President of the Public Entity stating that in the good faith judgment of the board of directors it would be seriously detrimental to the Public Entity and its equity holders for such registration statement to be filed at the time filing would be required and it is therefore essential to defer the filing of such registration statement, the Public Entity shall have the right to defer such filing for a period of not more than one hundred twenty (120) days after receipt of the request of the Holders, and provided, further, that the Public Entity shall not defer its obligation in this manner more than once in any twelve (12) month period;

(vi) in any particular jurisdiction in which the Public Entity would be required to qualify to do business or to execute a general consent to service of process in effecting such registration, qualification or compliance; or

(vii) unless the Registrable Securities are to be distributed by means of a firm commitment underwriting.

62

(b) The Public Entity (together with all Holders proposing to distribute their securities through such underwriting) shall enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting by the Public Entity in its sole discretion. Notwithstanding any other provision of this Section 11.03, if the underwriter advises the Initiating Holders that marketing factors require a limitation of the number of shares to be underwritten, the Registrable Securities that would otherwise be underwritten pursuant hereto, and the number of shares of Registrable Securities that may be included in the registration and underwriting shall be allocated among the Holders thereof in proportion, as nearly as practicable, to the respective amounts of Registrable Securities held by such Holders at the time of filing of the registration statement. If any Holder of Registrable Securities disapproves of the terms of the underwriting, such Person may elect to withdraw therefrom by written notice to the Public Entity, the managing underwriter and the Initiating Holders. The Registrable Securities so excluded or withdrawn shall not be Transferred in a public distribution prior to ninety (90) days after the effective date of such registration. If by the withdrawal of such Registrable Securities a greater number of Registrable Securities held by other Holders may be included in such registration (up to the maximum of any limitation imposed by the underwriters), then the Public Entity shall offer to all Holders who have included Registrable Securities in the registration the right to include additional Registrable Securities in the same proportion used in determining the underwriter limitation in this Section 11.03(b). If the underwriter has not limited the number of Registrable Securities to be underwritten, the Public Entity may include securities for its own account if the underwriter so agrees and if the number of Registrable Securities which would otherwise have been included in such registration and underwriting will not thereby be limited.

Section 11.04 Piggyback Registration Rights.

(a) If, at any time or from time to time, beginning with the Public Entity’s Qualified Public Offering, the Public Entity shall determine to register any of its securities for its own account in connection with an underwritten offering of its securities to the general public for cash on a form which would permit the registration of Registrable Securities (including but not limited to the Public Entity’s Qualified Public Offering), the Public Entity will:

(i) promptly give to each Holder written notice thereof; and

(ii) include in such registration and in the underwriting involved therein, all the Registrable Securities specified in a written request or requests, made within twenty (20) days after mailing or personal delivery of such written notice from the Public Entity, by any Holders, except as set forth in Section 11.04(b).

(b) Underwriting. The right of any Holder to registration pursuant to this Section 11.04 shall be conditioned upon such Holder’s participation in the underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to distribute their Registrable Securities through such underwriting shall (together with the Public Entity) enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting by the Public Entity. Notwithstanding any other provision of this Section 11.04, if the underwriter determines that marketing factors require a limitation of the number of shares to be underwritten, the Public Entity shall so advise all Holders whose securities would otherwise be registered and underwritten pursuant hereto, and the number

63

of shares of Registrable Securities that may be included in the registration and underwriting shall be allocated in the following manner: (i) first, to the Public Entity for securities being sold for its own account; then (ii) among all Holders in proportion, as nearly as practicable, to the respective amounts of Registrable Securities entitled to inclusion in such registration held by such Holders at the time of filing the registration statement, or, if so determined by the underwriter, all Registrable Securities shall be excluded from each registration and underwriting. If any Holder disapproves of the terms of any such underwriting, the Holder may elect to withdraw therefrom by written notice to the Public Entity and the underwriter. Any Registrable Securities so excluded or withdrawn shall not be Transferred in a public distribution prior to ninety (90) days after the effective date of such registration statement.

Section 11.05 Tag Along Rights

(a) Subject to Section 11.13, if one or more Units (Capital) Limited Partners or any of their Affiliates (collectively, a “Selling Partner”) desires to effect (i) a Transfer of Units representing 50% or more of the outstanding Units (Capital) in a single transaction or a series of related transactions, or (ii) a Transfer of Units that when aggregated with all other prior Transfers of Units (Capital) (whether or not constituting a Tag Sale) equals 50% or more of the total Units (Capital) issued by the Partnership under this Agreement (each Transfer of Units under clause (i) or (ii) a “Tag Sale,” and any subsequent Transfer of Units shall also be deemed a Tag Sale) and it does not elect to exercise its rights, if any, under Section 11.01 of this Agreement to require each non-Selling Partner (each, a “Co-Seller”) to Transfer their Units, then at least fifteen (15) days prior to the closing of such Tag Sale, the Selling Partner shall make a written offer (the “Participation Offer”) to each Co-Seller to include in the proposed Tag Sale a portion of:

(i) the number of Units (Capital) equal to the product of:

(A) the sum of (x) the total number of Units (Capital) owned by the Co-Seller immediately prior to the Tag Sale and (y) the aggregate number of such Co-Seller Units (Capital) previously sold in Tag Sales; and

(B) the sum of (x) the percentage of the total number of Units (Capital) being sold by the Selling Partner in the Tag Sale and (y) the percentage of the total number of Units (Capital) previously sold by all Selling Partners prior to the Tag Sales;

minus the aggregate number of such Co-Seller’s Units (Capital) previously sold in Tag Sales; and

(ii) the number of Units (Profits Interest) equal to the product of:

(A) the sum of (x) the total number of Units (Profits Interest) owned by the Co-Seller immediately prior to the Tag Sale and (y) the aggregate number of such Co-Seller Units (Profits Interest) previously sold in Tag Sales; and

(B) the sum of (x) the percentage of the total number of Units (Capital) being sold by the Selling Partner in the Tag Sale and (y) the percentage of the total number of Units (Capital) previously sold by all Selling Partners prior to the Tag Sales;

minus the aggregate number of such Co-Seller’s Units (Profits Interest) previously sold in Tag Sales.

64

Notwithstanding the foregoing, if the consideration to be received by the Selling Partner includes any securities, then, unless the Selling Partner and the Transferee both reasonably determine that an exemption is otherwise available under the Securities Act and all applicable state securities laws for such transaction, only Co-Sellers who have certified to the reasonable satisfaction of the Selling Partner that they are Accredited Investors shall be entitled to receive securities; the non-Accredited Investors shall be entitled to receive from the Partners selling Units in the applicable transaction, pro rata, in lieu of such securities, an amount, in cash, equal to the Fair Market Value (as determined pursuant to Section 11.09) of the portion of the Units held by the non-Accredited Investors that would otherwise be exchanged in consideration for such securities. The Units of any Co-Seller sold in any Tag Sale shall entitle such Co-Seller to receive the amount which such Co-Seller would receive if Section 7.01 of this Agreement were applied to the Tag Sale Value for a particular Tag Sale, and, as a result of such application, amounts would be distributed to the holders of Units pursuant to Section 7.01 of this Agreement. For the avoidance of doubt, the terms of this Section 11.05 shall continue following a Qualified Public Offering.

(b) The Participation Offer shall describe the terms and conditions of the proposed Tag Sale (including the number of Units to be sold) which shall be no less favorable than the terms and conditions obtained by the Selling Partner and shall be conditioned upon (i) the consummation of the transactions contemplated in the Participation Offer with the Transferee named therein and (ii) each Co-Seller’s execution and delivery of all agreements and other documents as the Selling Partner is required to execute and deliver in connection with such Tag Sale. If any Co-Seller shall accept the Participation Offer by written notice to the Selling Partner within ten (10) days after the date on which such Co-Seller receives the Participation Offer, the Selling Partner shall reduce, to the extent necessary, the number of Units (Capital) it otherwise would have sold in the proposed Transfer so as to permit those Co-Sellers who have accepted the Participation Offer to sell the number of their Units that they are entitled to sell under this Section 11.05 and the Selling Partner and such Co-Sellers shall Transfer the number of Units specified in the Participation Offer to the proposed Transferee in accordance with the terms of such Transfer as set forth in the Participation Offer. If any Selling Partner is subject to any indemnification holdback in the consideration paid to it for Units sold pursuant to this Section 11.05, any Units (Profits Interest) Limited Partner who sells any of its Units pursuant to the terms of this Section 11.05 shall be subject to the same indemnification holdback as the Selling Partner, in accordance with such Units (Profits Interest) Limited Partner’s proportional share of the Units sold.

Section 11.06 Certain Events Not Deemed Transfers

In no event shall any exchange, reclassification, or other conversion of Units into any cash, securities, or other property pursuant to a merger or consolidation of the Partnership with, or any sale or Transfer by the Partnership of all or substantially all its assets to, any Person constitute a Tag Sale for purposes of Section 11.05 of this Agreement. In addition, Section 11.05 of this Agreement shall not apply to any Transfer, sale or disposition of Units to an Affiliate of a Partner.

65

Section 11.07 Transfer and Exchange

When Units are presented to the Partnership with a request to register the Transfer of such Units or to exchange such Units for Units of other authorized denominations, the Partnership shall register the Transfer or make the exchange as requested if the requirements of this Agreement for such transaction are met; provided, however, that the Units surrendered for Transfer or exchange shall be duly endorsed or accompanied by a written instrument of Transfer in form satisfactory to the Partnership, duly executed by the holder thereof or its attorney and duly authorized in writing. No service charge shall be made for any registration of Transfer or exchange, but the Partnership may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith.

Section 11.08 Vesting Terms; Redemption/Forfeiture

(a) General. All Transferees (including spouses and former spouses) of holders of Units (Profits Interest) shall be subject to this Section 11.08 regardless of the fact that any such Transferee is not an employee of the Partnership or its Subsidiaries (i.e., if the employment of the Units (Profits Interest) Limited Partner who Transferred the Units (Profits Interest) to such Transferee is terminated, this Section 11.08 shall apply to such Units (Profits Interest) regardless of their ownership).

(b) Vesting Schedule. Subject to Section 11.08(c)(iii) of this Agreement, the Units (Profits Interest) held by a Units (Profits Interest) Limited Partner shall vest in equal installments of 25% annually over a four year period, beginning on the Grant Date. Unvested Units (Profits Interest) shall fully vest upon the occurrence of (i) a Qualified Public Offering, (ii) a Liquidation Event, (iii) a Transfer in a single transaction or a series of related transactions of 50% or more of the outstanding Units (Capital), (iv) an Approved Sale or (v) a Reorganization; provided that, in the case of (ii) and (iii), if requested by the third-party buyer or merger partner, and subject to clause (D) below:

(A) if the transaction or event does not permit or result in distributions or payments (whether upon a sale or otherwise) with respect to the Units (Profits Interest) that were vested immediately prior to the transaction or event, then all Units (Profits Interest) shall be immediately vested except Units (Profits Interest) equal to the 25% of the Units (Profits Interest) that were unvested immediately prior to the transaction or event (the “Retained Units”) shall continue to be unvested and held by the Units (Profits Interest) Limited Partner holding such Units subject to clause (C) below;

(B) if the transaction or event permits or results in distributions or payments (whether upon a sale or otherwise) with respect to the Units (Profits Interest) that were vested immediately prior to the transaction or event, then all Units (Profits Interest) shall be immediately vested except the cash or other items that would have been distributed or paid with respect to Units (Profits Interest) equal to the 25% of the Units (Profits Interest) that were unvested immediately prior to the transaction or event net of the Assumed Tax Liability with respect thereto (which shall be immediately distributed) (the “Withheld Items”) shall be withheld subject to clause (C) below;

66

(C) Retained Units under clause (A) above and all Withheld Items under clause (B) above shall be immediately vested or released, as the case may be, to the relevant Units (Profits Interest) Limited Partners upon the earlier of the first anniversary of the consummation of any transaction or event described in Section 11.08(b) and the fourth anniversary of the date of the issuance of such Units (Profits Interest). Prior to such release, the Retained Units and Withheld Items shall be subject to the forfeiture and redemption provisions consistent with the terms of Section 11.08(c) as if they were unvested Units (Profits Interest). In addition, upon a Units (Profits Interest) Limited Partner ceasing to be an Employee for any reason other than Cause, the vesting of the terminated Units (Profits Interest) Limited Partner’s Units (Profits Interest), in the sole discretion of the Board of Directors, may be accelerated. As to Retained Units, the Units (Profits Interest) Limited Partners shall be entitled to receive distributions of the Assumed Tax Liabilities prior to the release and other distributions with respect thereto shall be treated as Retained Distributions;

(D) such third-party buyer or merger partner must agree to establish mechanisms, reasonably acceptable to the Holders of a majority in interest of such the Retained Units and/or Withheld Items, to assure that such holders shall receive any Withheld Items, Retained Distributions allocable to such holders subject to the vesting and other provisions of clause (C) above.

(c) Redemption/Forfeiture.

(i) If a Limited Partner ceases to be an Employee as a result of termination by a member of the PEG Group for Cause, (A) all Units (Profits Interest) (whether vested or unvested) held by such Limited Partner shall be automatically forfeited to the Partnership at the termination date without further action on the part of the Partnership or such former Employee and (B) the Partnership will have the option to repurchase any Units (Capital) owned by such former Employee for the Fair Market Value of such Units (Capital), provided that the Partnership must consummate such repurchase within thirty (30) days of such Limited Partner’s termination.

(ii) If a Limited Partner ceases to be an Employee as a result of such Limited Partner’s termination other than for Good Reason, (A) all unvested Units (Profits Interest) held by such Limited Partner shall automatically be forfeited to the Partnership at the termination date without further action on the part of the Partnership or such former Employee and (B) the Partnership will have the option to repurchase any Units (Capital) and any vested Units (Profits Interest) owned by such former Employee for the Fair Market Value of such Units, provided that the Partnership must consummate such repurchase within thirty (30) days of such Units (Profits Interest) Limited Partner’s termination.

67

(iii) If a Limited Partner ceases to be an Employee as a result of (A) termination by a member of the PEG Group for other than Cause, (B) non-renewal by a member of the PEG Group of such Limited Partner’s Employment Agreement prior to the full vesting of the initial Units (Profits Interest) issued to such Units (Profits Interest) Limited Partner, (C) Good Reason, or (D) death or Disability, (1) vesting of any unvested Units (Profits Interest) owned by such Limited Partner shall be accelerated by twelve (12) months, (2) any Units (Profits Interest) owned by such Limited Partner that remain unvested after taking into account such twelve-month acceleration shall automatically be forfeited to the Partnership at the termination date without further action on the part of the Partnership or such former Employee and (3) the Partnership will have the option to repurchase any vested Units (Profits Interest) and any Units (Capital) owned by such former Employee for the Fair Market Value of such Units, provided that the Partnership must consummate such repurchase within thirty (30) days of such Limited Partner’s termination.

(iv) Each Limited Partner explicitly acknowledges and agrees that, if the Partnership elects to repurchase any Units (Profits Interest) or any Units (Capital) pursuant to the provisions of Section 11.08(c)(i), (ii), or (iii) above, then such Limited Partner shall be selling his goodwill in the Partnership and otherwise disposing of his ownership interest in the Partnership, and in consideration for such sale and disposal, except as otherwise permitted in such Units (Profits Interest) Limited Partner’s Employment Agreement, if applicable, or with respect to a Units (Profits Interest) Limited Partner as of the Effective Date, the Amended and Restated Agreement of Limited Partnership of the Initial Limited Partner, expressly agrees that for a period of twelve (12) months after the consummation of the repurchase contemplated by Section 11.08(c)(i), (ii), or (iii) he shall not, directly or indirectly, without prior written approval of the Partnership, for himself or on behalf of or in conjunction with any other person or entity of whatever nature:

(A) engage or participate within the Market Area in a Competitive Business;

(B) solicit any Employee to terminate his or her employment with any member of the PEG Group; or

(C) engage or participate in an auction or sale process for assets or solicit any counterparty for the delivery of power as to which the Partnership or any of its Subsidiaries had been, at the time of his termination, targeting or evaluating for development, negotiating for any option or acquisition, or preparing to act as a participant in any auction or sale process (the “Identified Development Properties”).

The covenants in this Section 11.08(c)(iv) are severable and separate and the unenforceability of any specific covenant shall not affect the provisions of any other covenant in this Agreement.

Because of the difficulty in measuring economic losses to the Partnership as a result of a breach of any of the covenants in this Section 11.08(c)(iv), and because of the immediate and irreparable damage that could be caused to the Partnership for which it would have no other adequate remedy, the Units (Profits Interest) Limited Partner agrees that the covenants in this Section 11.08(c)(iv) may be enforced by the Partnership, in the event of a breach, by injunctions and restraining orders and that such enforcement is in addition to all other rights and remedies that may be available to the Partnership at law and equity.

68

As used in this Section 11.08(c)(iv), the term “Market Area” shall mean any area within a 100 mile radius from (i) the location of a power generation or transmission facility in which the Partnership or its Subsidiaries have an economic or other business interest and (ii) the Identifiable Development Properties. The term “Competitive Business” shall mean any business in which: (i) the Partnership or any of its Subsidiaries have engaged during the term of the Units (Profits Interest) Limited Partner’s employment; and (ii) continues to engage during some or all of the restrictive period referenced in this Section 11.08(c)(iv). For the avoidance of doubt, with respect to each Units (Profits Interest) Limited Partner as of the Effective Date, nothing herein shall limit or restrict, or be deemed a “Competitive Business” with, any activities described in this Section 11.08(c)(iv) by such Units (Profits Interest) Limited Partner to the extent any such activity is otherwise permitted under such Units (Profits Interest) Limited Partner’s Employment Agreement or the Amended and Restated Agreement of Limited Partnership of the Initial Limited Partner.

(v) Unless the Board of Directors elects to make payment in cash, payment for any Units purchased by the Partnership pursuant to Section 11.08(c)(i) of this Agreement shall be in the form of a promissory note, subordinated to all indebtedness for borrowed money of the Partnership that the Board of Directors determines are senior to such promissory note, with principal payable at the earlier of (i) the re-sale or other monetization of all or a portion of the repurchased vested Units to the extent of the proceeds of the sale or (ii) five (5) years from issuance and with interest to be paid annually on the unpaid balance of such principal at a rate that is equal to the interest rate, on the date of issuance, that is publicly quoted by ▇.▇. ▇▇▇▇▇▇ ▇▇▇▇▇ & Co. or its successor as its prime commercial or similar reference interest rate; provided, however, that payments of amounts due on such promissory note shall be accelerated to the extent necessary to cover any tax liability attributed to such Partner that is associated with such promissory note, as such amounts become due and are required to be paid.

(vi) Unless the Board of Directors elects to make payment in cash, payment for any Units purchased by the Partnership pursuant to Section 11.08(c)(ii) of this Agreement shall be in the form of a promissory note, subordinated to all indebtedness for borrowed money of the Partnership that the Board of Directors determines are senior to such promissory note, with principal and interest payable quarterly, amortized equally over three (3) years, at a rate that is equal to the interest rate, on the date of issuance, that is publicly quoted by ▇.▇. ▇▇▇▇▇▇ & Co. or its successor as its prime commercial or similar reference interest rate; provided, however, that payments of amounts due on such promissory note shall be accelerated to the extent necessary to cover any tax liability attributed to such Partner that is associated with such promissory note, as such amounts become due and are required to be paid. Notwithstanding the foregoing, if a sale or other monetization of all or a portion of the repurchased vested units occurs prior to the maturity of the note issued pursuant to this Section 11.08(c)(vi), the Partnership shall pay to the Units (Profits Interest) Limited Partner the proceeds from such sale to the extent of the remaining unpaid balance (and accrued but unpaid interest) at the time of such sale or other monetization. Notwithstanding the foregoing, if the total payment due to a Limited Partner for any Units purchased by the Partnership pursuant to Section 11.08(c)(ii) is less than $1,000,000, payment shall be made in cash.

69

(vii) Payment for the Units purchased by the Partnership pursuant to Section 11.08(c)(iii) of this Agreement shall be made in cash.

(viii) Notwithstanding any other provision of this Agreement, if a Units (Profits Interest) Limited Partner ceases to be an Employee and the Board of Directors with at least one Management Designee determines within ninety (90) days following the termination that Cause exists or existed on such termination (including by virtue of a material breach of an obligation to the Partnership under this Agreement or any employment agreement after such termination), (i) the percentage of Units (Profits Interest) held by such Units (Profits Interest) Limited Partner which have vested shall be reduced to 0% and all Units (Profits Interest) held by such Units (Profits Interest) Limited Partner or his direct or indirect Transferees shall automatically be forfeited to the Partnership without further action on the part of the Partnership or such Employee and (ii) to the extent that the Partnership has previously repurchased any Units (Profits Interest) held by such Units (Profits Interest) Limited Partner, all consideration for such Units (Profits Interest) previously paid by the Partnership must be returned by the Units (Profits Interest) Limited Partner to the Partnership.

(d) Recapture of Units (Profits Interest) held by Management Holdco. Any Management Holdco shall issue Management Holdco LLC Units only to Employees. The number of Management Holdco LLC Units outstanding shall at all times equal the number of Units (Profits Interest) held by such Management Holdco. The limited liability company agreement of Management Holdco shall provide for the vesting, forfeiture and repurchase of Management Holdco LLC Units on terms equivalent to those set forth in this Section 11.08. If any Management Holdco LLC Units are forfeited to Management Holdco, an equal number of Units (Profits Interest) held by Management Holdco shall be forfeited to the Partnership. If Management Holdco has the right to repurchase any Management Holdco LLC Units, Management Holdco shall exercise such right as directed by the Partnership. If the Partnership directs Management Holdco to repurchase any Management Holdco LLC Units, the Partnership shall repurchase an equal number of Units (Profits Interest) from Management Holdco for the same consideration. Any such repurchase of Units (Profits Interest) from Management Holdco may be structured in an alternative method, as determined by the Board of Directors, provided it is not economically disadvantageous to the applicable Employee.

Section 11.09 Determination of Fair Market Value

(a) For purposes of this Agreement, the “Fair Market Value” of any property means, as of any time of determination, the then fair market value of such property as determined in good faith by the Board of Directors, which determination shall be conclusive for all purposes; provided, however, that (i) solely with respect to the valuation of Units (Capital) and Units (Profits Interest) pursuant to Section 11.08(c), Section 12.03(b), or Section 12.03(d) of this Agreement, the Fair Market Value of any such Units (Capital) or Units (Profits Interest) shall be determined in accordance with the provisions of Section 11.09(b) and Section 11.09(c) of this Agreement and (ii) solely with respect to the valuation of Units (Capital) for purposes of Section 5.02(c), the Fair Market Value of such Units (Capital) shall be determined by an Independent Advisor selected by the Board of Directors pursuant to Section 5.02(c) in accordance with the provisions of Section 11.09(c) of this Agreement.

70

(b) The Fair Market Value of a Unit (Capital) or a Unit (Profits Interest) shall be determined, as of the effective date of the end of the Limited Partner’s active employment by a member of the PEG Group pursuant to Section 11.08(c) or as of the date the Partnership exercises its repurchase right pursuant to Section 12.03, by the Board of Directors in its good faith reasonable discretion, using the Partnership’s most recent previously issued annual or semi-annual financial statements and reserve reports available on the date on which such determination is being made by the Board of Directors. The Board of Directors shall provide prompt written notice to the Limited Partner (or spouse or former spouse) of its determination. The purchase of such Units (Capital) and/or Units (Profits Interest) interests shall close promptly thereafter, but in no case more than twenty (20) Business Days of, the giving of such notice.

(c) In the event that a Limited Partner (or spouse or former spouse) does not agree with any determination of the Fair Market Value of such Limited Partner’s (or spouse’s or former spouse’s) Units (Capital) or Units (Profits Interest), then within twenty (20) Business Days after the consummation of the purchase of Units (Capital) and/or Units (Profits Interest) pursuant to Section 12.03 or Section 11.08(b), the Limited Partner (or spouse or former spouse) shall notify the Board of Directors in writing of the existence of a dispute. The Limited Partner (or spouse or former spouse) and the Board of Directors shall seek to resolve the dispute for twenty (20) Business Days. In the event that no resolution is reached, the Board of Directors shall promptly select three nationally-recognized investment banking firms that have not had a direct or indirect substantial relationship with the Partnership within the last two years and notify the Limited Partner (or spouse or former spouse) thereof. The Limited Partner (or spouse or former spouse) shall promptly select one of the three investment banking firms and notify the Partnership thereof. If the Partnership has not received notice of selection of one of the investment banking firms within twenty (20) days of the date it gave notice to the Limited Partner (or spouse or former spouse) of the three investment banking firms, then the Board of Directors shall select one of such three. The investment banking firm selected as provided above with respect to the purchase of Units (Capital) and/or Units (Profits Interest) pursuant to Section 12.03 or Section 11.08(b) or selected by the Board of Directors pursuant to Section 5.02(c) (the “Independent Advisor”) shall promptly adjust or determine the Fair Market Value (as applicable). The Independent Advisor shall render its decision within twenty (20) Business Days and such decision shall be final and binding upon the parties. If the Fair Market Value as determined by the Independent Advisor is greater than the amount paid by the Partnership to the Limited Partner pursuant to Section 11.09(b), Section 12.03(b) or Section 12.03(d), or used as the basis for determining the number of Units (Capital) issued pursuant to Section 5.02(c), the Partnership will pay the Limited Partner an amount equal to the difference between such Fair Market Value as determined by the Independent Advisor and such amount paid by the Partnership pursuant to Section 11.09(b), Section 12.03(b) or Section 12.03(d), or shall reduce retroactively the number of Units (Capital) issued pursuant to Section 5.02(c), in a timely manner. If the Fair Market Value as determined by the Independent Advisor is less than the amount paid by the Partnership to the Limited Partner pursuant to Section 11.09(b), Section 12.03(b) or Section 12.03(d), the Limited Partner will pay the Partnership an amount equal to the difference between such Fair Market Value as determined by the Independent Advisor and such

71

amount paid by the Partnership pursuant to Section 11.09(b), Section 12.03(b) or Section 12.03(d), or the Partnership shall issue retroactively an additional number of Units (Capital) pursuant to Section 5.02(c), in a timely manner. With respect to any valuation relating to Section 11.09(b), Section 12.03(b), Section 12.03(d), in the event that (i) the Independent Advisor’s determination of Fair Market Value is more than 5% higher than the original determination made by the Board of Directors, the Partnership shall pay 100% of the cost of retaining the Independent Advisor, (ii) the Independent Advisor’s determination of Fair Market Value is more than 5% lower than the original determination made by the Board of Directors, the Limited Partner (or spouse or former spouse) requesting the Independent Advisor shall pay 100% of the cost of retaining the Independent Advisor, and (iii) in all other instances the Partnership shall pay 50% of the fees and expenses of retaining the Independent Advisor and the Limited Partner (or spouse or former spouse) the other 50%. With respect to any valuation relating to Section 5.02(c), the Partnership shall pay 100% of the cost of retaining the Independent Advisor.

Section 11.10 Substituted Limited Partners

(a) Unless a Transferee becomes a Substituted Limited Partner in accordance with Section 11.10(b), such Transferee shall not be entitled to any of the rights granted to a Limited Partner hereunder.

(b) Except with respect to allocations of forfeited Units (Capital) interests pursuant to Section 11.09(c), a Transferee of all or part of a Units (Capital) interest or a Units (Profits Interest) interest in accordance with Section 12.01 shall become a Substituted Limited Partner entitled to all the rights of a Units (Capital) Limited Partner or Units (Profits Interest) Limited Partner (relating to the Transferred portion of the Partnership Interest), respectively, if, and only if, (i) the Transferring Limited Partner requests the Transferee be granted such right and (ii) the Transferee executes and delivers such instruments (including Exhibit G) in form and substance satisfactory to the Board of Directors, as the Board of Directors may deem necessary or desirable to effect such substitution. The Partnership shall be entitled to treat the record owner of any Partnership Interest as the absolute owner thereof in all respects and shall incur no liability for distributions of cash or other property made to such owner until such time as a Transfer of such interest that complies with the terms of this Agreement has been effected. For the sake of clarity, in the event a Units (Capital) Limited Partner makes a Transfer of any of its Units (Capital) interests, this Section 11.10 will apply to the admission of the Transferee as a Substitute Limited Partner and Section 13.01 shall not apply.

Section 11.11 Transfer of Rights

Subject to Section 11.12, in connection with the Transfer of Units (Capital), the rights of the Riverstone Group under this Article XI with respect to such Units may be assigned or Transferred in whole or in part by the Riverstone Group without any consent or other action on the part of any other party hereto.

72

Section 11.12 Transfer

Notwithstanding the foregoing, without the prior consent of the Board of Directors, no Partner shall Transfer all or any part of its Units in such a manner that, after the Transfer, the Partnership would become taxable as a corporation for U.S. federal income tax purposes or if the Transfer, when added to other Transfers during the preceding twelve months, would result in a termination of the Partnership within the meaning of Section 708 of the Code.

Section 11.13 Taxable Non-Cash Transactions

Notwithstanding Section 7.02, Section 11.01, Section 11.02, or Section 11.05, the Partnership shall not make any distribution other than in cash or Marketable Securities that are not Restricted Securities, and neither the Partnership nor any Partner shall make or permit any Approved Sale, Reorganization, Recapitalization or Tag Sale not made solely for cash consideration or Marketable Securities that are not Restricted Securities (each, a “Taxable Non-Cash Transaction”), in each case, if the Assumed Non-Cash Transaction Tax Liability of any Partner arising as a result of such Taxable Non-Cash Transaction would exceed the amount of cash or Marketable Securities that are not Restricted Securities distributable or payable to such Partner in connection with such Taxable Non-Cash Transaction (such Partner, an “Affected Partner”), unless such Taxable Non-Cash Transaction is approved by either (i) all of the Affected Partners or (ii) the Units (Capital) Majority and the Units (Profits Interest) Majority.

LIMITATIONS ON TRANSFERS

Section 12.01 Restrictions on Transfer

(a) Except as otherwise contemplated by this Section 12.01, Section 11.01, Section 11.02 and Section 11.05 of this Agreement and except for the Transfer of Units (Capital) by any member of Riverstone Group which may be made without the approval of the Board of Directors or any other Partner, the Units shall not be Transferred or otherwise conveyed, assigned or hypothecated before satisfaction of (a) the conditions specified in this Section 12.01, (b) if applicable, the provisions of Article XI hereof and (c) consent of the Board of Directors in its sole discretion. Any purported Transfer in violation of this Article XII and/or, if applicable, the provisions of Article XI hereof shall be void ab initio and of no force or effect. Other than Transfers pursuant to Article XI hereof, each Partner will cause any proposed Transferee of any Unit to agree in writing, in an instrument in form and substance reasonably satisfactory to the Partnership, to take and hold such securities subject to the provisions and upon conditions specified in this Agreement. No Person shall make or suffer any Transfer of its, his or her Units if such Transfer would (a) cause the Partnership or any Partner to become subject to regulation under either the Investment Company Act of 1940, as amended, or the Investment Advisers Act of 1940, as amended, or (b) violate the registration provisions of the Securities Act or the registration or qualification provisions of any applicable securities law. Notwithstanding anything else to the contrary herein, Riverstone may effect Transfers at any time without consent of the Board of Directors or any other Partner.

(b) Any Limited Partner who is an individual may Transfer by way of gift all or any of its Units to a spouse, lineal ancestor, lineal descendant, legally adopted child, brother or sister of such Partner, or lineal descendant or legally adopted child of a brother or sister of such Partner (a “Family Member”) or to a trust or other entity whose sole and exclusive beneficiaries are such Partner and/or Family Members of such Partner, but only to the extent (i) such Transferee executes and delivers to the Partnership an Adoption Agreement in the form of Exhibit G hereof, and (ii) the Board of Directors consents to such Transfer, which consent shall not be unreasonably withheld.

73

(c) The Units (Profits Interest) Limited Partners may Transfer Units (Profits Interest) to other Employees (including those who are already Units (Profits Interest) Limited Partners) without approval of the Board or the restrictions in this Agreement, provided that the Transferring Units (Profits Interest) Limited Partner provides the Board with ten (10) days prior written notice of the proposed Transfer and the Board has not provided written objection to such Transfer within such period. Any such Person to whom a Transfer is made shall be obligated to enter into this Agreement if such Person was not a Units (Profits Interest) Limited Partner prior to the Transfer. The Board of Directors will reasonably cooperate with the Transferring Units (Profits Interest) Limited Partner in effecting the Transfer. The Partnership Representative shall make such adjustments to the Capital Account maintenance and allocation provisions in Section 5.06 and Article VI as it reasonably determines necessary to account for such Transfer.

Section 12.03 Spouses

(a) As a condition to becoming or remaining a Limited Partner, each Limited Partner that is an individual and is or becomes married, shall cause his spouse to execute an agreement in the form of Exhibit F hereof. If an existing Limited Partner fails to have his or her spouse execute such agreement, the Limited Partner shall thereafter lose all their rights hereunder except for the rights of a mere assignee under the Act and the Board of Directors shall thereafter have all voting rights with respect to his or her interest.

(b) Any Units held by an individual who has failed to cause his or her spouse to execute an agreement in the Form of Exhibit F and any Units held by a person who is an assignee shall be subject to the option of the Partnership or the Riverstone Group or any of their respective Affiliates to acquire all of such Units for the Fair Market Value of the Units (Capital) and the then vested Units (Profits Interest).

(d) If a spouse or former spouse of a Limited Partner acquires a Unit in the Partnership without prior Board Approval, such spouse or former spouse hereby grants, as evidenced by Exhibit F, an irrevocable power of attorney (which shall be coupled with an interest) to the original Limited Partner who held such Units, as the case may be, to vote or to give or withhold such approval as such original Limited Partner shall himself or herself vote or approve with respect to such matter and without the necessity of the taking of any action by any such spouse or former spouse. Such power of attorney shall not be affected by the subsequent disability or incapacity of the spouse or former spouse granting such power of attorney. Furthermore, such spouse or former spouse agrees that the Partnership or the Riverstone Group or any of their respective Affiliates shall have the option at any time to purchase all of such Units for the Fair Market Value of the Units (Capital) and the then vested Units (Profits Interest).

Section 12.04 Termination of Certain Restrictions

Notwithstanding the foregoing provisions of this Article XII, the legend requirements of Section 12.02(a) of this Agreement shall terminate as to any Unit (a) when and so long as such Unit shall have been effectively registered under the Securities Act and disposed of pursuant thereto or disposed of pursuant to the provisions of Rule 144 thereof or (b) when the Partnership shall have received an opinion of counsel (or such other evidence) reasonably satisfactory to it that such Unit may be Transferred without registration thereof under the Securities Act and that such legend may be removed. Whenever the restrictions imposed by Section 12.02(a) of this Agreement shall terminate as to any Unit, the holder thereof shall be entitled to receive from the Partnership, at the Partnership’s expense, a new Unit not bearing the restrictive legend set forth in Section 12.02(a) of this Agreement.

Section 15.05 Entire Agreement; Amendments

(a) This Agreement and its exhibits constitute the entire agreement among the Partners relative to the formation of the Partnership and supersedes all prior contracts or agreements with respect to the Partnership, whether oral or written. Except as set forth below, no amendment of this Agreement will be valid or binding upon the Partners, nor will any waiver of any term of this Agreement be effective, unless in writing and signed by (i) a Units (Capital) Majority and (ii) the Board of Directors; provided that no amendment or waiver of this Agreement shall be effected that disproportionately and adversely affects the holders of Units (Profits Interest), in their capacities as such, without the consent of the Units (Profits Interest) Majority.

(b) Notwithstanding the foregoing, no amendment of this Agreement may be made without the consent of 100% of the outstanding Units (Profits Interest) if such amendment would:

(i) impose upon any Units (Profits Interest) Limited Partner the obligation to make contributions to the capital of the Partnership other than in their capacity as a Units (Capital) Limited Partner;

(ii) result in any Units (Profits Interest) Limited Partner being or having the liability of, a general partner, convert any Units (Profits Interest) Limited Partner’s interest in the Partnership into a general partnership interest, or modify the limited liability of any Units (Profits Interest) Limited Partner in any manner adverse to such Units (Profits Interest) Limited Partner; or

80

(iii) amend any provisions provided in the foregoing clauses (i) and (ii).

(c) Notwithstanding the foregoing, no amendment of this Agreement may be made without the consent of 80% of the outstanding Units (Profits Interest) (which consent, for the avoidance of doubt, shall not require a formal vote of all Units (Profits Interest) Limited Partners but shall be effective upon provision of a consent signed by such Units (Profits Interest) Limited Partners representing at least 80% of the outstanding Units (Profits Interest)) if such amendment would:

(i) provide for any Units (Profits Interest) Limited Partner to receive any distribution other than pari passu with all other Units (Profits Interest) Limited Partners, based on their respective Unit (Profits Interest) Sharing Percentages (as adjusted to take into account any Threshold Amount applicable to any tranche of Units (Profits Interest)), or decrease any Units (Profits Interest) Limited Partner’s Unit (Profits Interest) Sharing Percentage in any manner which would not decrease all Units (Profits Interest) Limited Partners’ respective Unit (Profits Interest) Sharing Percentages on a proportionate basis;

(ii) decrease any Units (Profits Interest) Limited Partner’s rights to receive distributions in an amount equal to such Units (Profits Interest) Limited Partner’s Assumed Tax Liability or amend Section 11.13 of this Agreement;

(iii) decrease any Units (Profits Interest) Limited Partner’s voting rights hereunder;

(iv) increase the number of authorized Units (Profits Interest); or

(v) amend any provisions provided in the foregoing clauses (i), (ii), (iii) and (iv). Clauses (i)-(iv) shall not prevent the Partnership from enforcing a redemption or forfeiture of Units (Profits Interest) contemplated by Section 11.08, and such redemption and forfeiture shall not be deemed to be a reduction in rights to receive distributions, decrease in voting rights, or increase in authorized Units (Profits Interest).

(d) Notwithstanding the foregoing, the Board of Directors shall be authorized to amend this Agreement, without the approval of any Partner, pursuant to Article XIII and with respect to any of the following matters:

(i) entering into agreements with Persons that are Transferees or new Partners pursuant to the terms of this Agreement, providing that such Transferees or new Partners will be bound by this Agreement and will become Partners of the Partnership and in accordance with Article XII of this Agreement;

(ii) amending this Agreement (A) to satisfy any requirements, conditions, guidelines or opinions contained in any opinion, directive, order, ruling or regulation of the Securities and Exchange Commission, the Internal Revenue Service or any other U.S. federal or state or non-U.S. governmental agency, or in any U.S. federal or state or non-U.S. statute, compliance with which the Board of Directors deems to be in the best interest of the Partnership, or (B) to change the name of the Partnership;

81

(iii) amending this Agreement to cure any ambiguity or correct or supplement any provision hereof that may be incomplete or inconsistent with any other provision hereof, so long as such amendment under this Section 15.05(d)(iii) does not adversely affect the interests of the Partners; and

(iv) amending this Agreement upon publication of final regulations in the Federal Register (or other official pronouncement), to provide for (A) the election of a safe harbor under U.S. Treasury Regulations Section 1.83-3(1) (or any similar provision) under which the fair market value of a partnership (or membership) interest that is Transferred in connection with the performance of services is treated as being equal to the liquidation value of that interest, (B) an agreement by the Partnership and all of its Partners to comply with all the requirements set forth in such regulations and Revenue Procedure 2005-43 (and any other guidance provided by the Internal Revenue Service with respect to such election) with respect to all partnership (or membership) interests Transferred in connection with the performance of services while the election remains effective, and (C) any other related amendments.

Section 15.06 Confidentiality

Each Partner agrees that all non-public information received from or otherwise relating to, the Partnership, the Riverstone Group, or any third party who has entrusted the Partnership with confidential information with the expectation that such information will be kept confidential, is confidential and will not be (i) disclosed or otherwise released to any other Person (other than another party hereto for a valid business purpose) or (ii) used for anything other than as necessary and appropriate in carrying out the business of the Partnership. The obligations of the parties hereunder do not preclude the Riverstone Group from disclosing information to its direct and indirect beneficial owners or representatives or as it may reasonably deem to be appropriate in connection with fundraising efforts. The restrictions set forth herein do not apply to any disclosures required by applicable law or securities exchange rule or regulation, so long as (x) the Person subject to such disclosure obligations provides prior written notice (to the extent reasonably practicable) to the Partnership stating the basis upon which the disclosure is asserted to be required, and (y) upon the Partnership’s request, the Person subject to such disclosure obligations takes all reasonable steps to oppose or mitigate any such disclosure.

Section 15.07 Non-Disparagement

Each Partner agrees that, in communications with Persons other than the Partners and the Partnership (and their respective Affiliates, employees, members and partners or employees of Affiliates of Partners or the Partnership), he or she shall not disparage in any material way, the Partnership, and each other Partner (and their Affiliates, members and partners). Under no circumstances shall any Partner, in communications with Persons other than the Partners and the Partnership (and their respective Affiliates, employees, members and partners or employees of Affiliates of Partners or the Partnership), criticize or disparage any business practice, policy, statement, valuation or report that is made, conducted or published by the Partnership or any other

82

Partner (and their Affiliates, members and partners) in any material way. Notwithstanding the foregoing, this Section 15.07 shall not be construed to prohibit or restrain any criticism or other statements made, directly or indirectly, (i) exclusively between or among any of the Partners, the Partnership, their Affiliates, members, partners, or their respective employees or attorneys, to the extent such communications or statements are made in the ordinary course of business (ii) in connection with litigation, (iii) required under law or (iv) exclusively between a Partner and a member of such Partner’s Immediate Family. The obligations of each Partner under this Section 15.07 shall continue after the date such Person ceases to be a Partner, but thereafter such Person shall not have the right to enforce the provisions of this Agreement.

Section 15.08 Waiver

No consent or waiver, express or implied, by any Partner of any breach or default by any other Partner in the performance by the other Partner of his, her or its obligations hereunder shall be deemed or construed to be a consent or waiver to or of any other breach or default in the performance by such other Partner of the same or any other obligation hereunder. Failure on the part of any Partner to complain of any act or to declare any other Partner in default, regardless of how long such failure continues, shall not constitute a waiver of rights hereunder.

Section 15.09 Severability

If any provision of this Agreement or the application thereof to any Person or circumstances shall be invalid or unenforceable to any extent, and such invalidity or unenforceability does not destroy the basis of the bargain between the parties, then the remainder of this Agreement and the application of such provisions to other Persons or circumstances shall not be affected thereby and shall be enforced to the greatest extent permitted by law.
