Formation of Midstream Partnership

On May 1, 2013, OGE Energy Corp. ("OGE"), two affiliates of ArcLight Capital Partners, LLC (Bronco Midstream Holdings, LLC ("Bronco I") and Bronco Midstream Holdings II, LLC (together with Bronco I, the "Bronco Group")), and CenterPoint Energy, Inc. ("CenterPoint"), completed the formation of the previously announced joint venture to own and operate the midstream businesses of OGE and a wholly owned subsidiary of CenterPoint, CenterPoint Energy Resources Corp. ("CERC").

Pursuant to the terms of the previously reported Master Formation Agreement dated as of March 14, 2013 (the "MFA"), OGE and the Bronco Group indirectly contributed 100 percent of the equity interests in Enogex LLC, a Delaware limited liability company ("Enogex"), to the midstream partnership. CenterPoint Energy Field Services, LLC, a Delaware limited liability company and wholly owned subsidiary of CERC ("CEFS"), was converted into a Delaware limited partnership that became the midstream partnership (the "Midstream Partnership"). CERC contributed to the Midstream Partnership CERC's equity interests in each of CenterPoint Energy Gas Transmission Company, LLC, a Delaware limited liability company ("CEGT"), CenterPoint Energy - Mississippi River Transmission, LLC, a Delaware limited liability company ("MRT"), and certain of its other midstream subsidiaries and a portion of its interests in Southeast Supply Header, LLC, a Delaware limited liability company ("SESH").

At May 1, 2013, OGE, through its wholly owned subsidiary OGE Enogex Holdings LLC ("OGEH"), holds 28.5 percent of the limited partner interests, CERC holds 58.3 percent of the limited partner interests and the Bronco Group holds 13.2 percent of the limited partner interests in the Midstream Partnership.

CERC has certain put rights, and the Midstream Partnership has certain call rights, exercisable with respect to the interest in SESH retained by CERC, under which CERC would contribute to the Midstream Partnership CERC's retained interest in SESH at a price equal to the fair market value of such interest at the time the put right or call right is exercised. If CERC were to exercise such put right or the Midstream Partnership were to exercise such call right, CERC's retained interest in SESH would be contributed to the Midstream Partnership in exchange for consideration consisting of a specified number of limited partnership units and, subject to certain restrictions, a cash payment, payable either from CERC to the Midstream Partnership or from the Midstream Partnership to CERC, in an amount such that the total consideration exchanged is equal in value to the fair market value of the contributed interest in SESH.

The general partner of Midstream Partnership is equally controlled by CERC and OGE, who each have 50 percent of the management rights. CERC and OGE also own a 40 percent and 60 percent interest, respectively, in any incentive distribution rights to be held by the general partner of the Midstream Partnership. In addition, for a period of time, the Bronco Group, through its ownership in Enogex Holdings LLC ("Enogex Holdings"), which will become wholly owned by the Bronco Group as a result of the transactions contemplated by the Master Formation Agreement, will have board observation rights and approval rights over certain material activities of the Midstream Partnership, including material increases in capital expenditures and certain equity issuances, entering into transactions with related parties and acquiring, pledging or disposing of certain material assets. The general partner of the Midstream Partnership will initially be governed by a board made up of an equal number of representatives designated by each of CenterPoint and OGE. Based

on the 50/50 management ownership, with neither company having control, effective May 1, 2013, OGE deconsolidated its interest in Enogex and will account for its interest in the Midstream Partnership under the equity method of accounting.

CenterPoint has designated David M. McClanahan, president and chief executive officer of CenterPoint, and Gary L. Whitlock, executive vice president and chief financial officer of CenterPoint, and OGE has designated Peter B. Delaney, chairman, president and chief executive officer of OGE, and Sean Trauschke, vice president and chief financial officer of OGE, as their initial representatives on the board of directors of the general partner. While the Midstream Partnership's leadership team is being assembled, C. Gregory Harper and Keith Mitchell will continue to be responsible for the former CenterPoint and Enogex midstream operations, respectively.

OGE Energy Corp. is the parent company of Oklahoma Gas and Electric Company, a regulated electric utility with approximately 801,000 customers in Oklahoma and western Arkansas, and OGEH, which indirectly owns a majority share in Enogex. Enogex is a midstream natural gas pipeline business with principal operations in Oklahoma. Enogex is a provider of integrated natural gas midstream services in the major producing basins of Oklahoma and portions of the Texas Panhandle. With approximately 8,900 miles of pipelines, nine processing plants, 24 billion cubic feet of storage, and more than 2.5 million net acres dedicated, including dedications in the Granite Wash, Cleveland Sands, Tonkawa, Cana Woodford, Colony Wash and Mississippi Lime plays, Enogex is engaged in the gathering, processing, transportation and storage of natural gas. During 2012, Enogex gathered an average of 1.41 trillion British thermal units per day ("TBtu/d"), processed an average of 0.98 TBtu/d and transported an average of 2.08 TBtu/d.

CEFS provides natural gas gathering and processing services for certain natural gas fields in the Mid-continent region of the United States that interconnect with CEGT's and MRT's pipelines, as well as other interstate and intrastate pipelines. As of December 31, 2012, CEFS gathered an average of approximately 2.5 billion cubic feet ("Bcf") per day of natural gas. In addition, CEFS has the capacity available to treat up to 2.5 Bcf per day and process nearly 625 million cubic feet per day of natural gas. CEGT is an interstate pipeline that provides natural gas transportation, storage and pipeline services to customers principally in Arkansas, Louisiana, Oklahoma and Texas and includes the 1.9 Bcf per day pipeline from Carthage, Texas to Perryville, Louisiana, which CEGT operates as a separate line with a fixed fuel rate. MRT is an interstate pipeline that provides natural gas transportation, storage and pipeline services to customers principally in Arkansas, Illinois and Missouri. CERC indirectly owns a 50 percent interest in SESH, which owns a 1.0 Bcf per day, 274-mile interstate pipeline that runs from the Perryville Hub in Louisiana to Coden, Alabama. A wholly owned indirect subsidiary of Spectra Energy Corp. owns the remaining 50 percent interest in SESH.

Limited Partnership Agreement and General Partner LLC Agreement

Pursuant to the terms of the First Amended and Restated Agreement of Limited Partnership (the "Partnership Agreement") of the Midstream Partnership dated as of May 1, 2013 among CNP OGE GP LLC, as general partner, and CERC, OGEH and Enogex Holdings, as limited partners, the Midstream Partnership will be managed by the general partner. For a period of time, Enogex Holdings will have board observation rights and approval rights over certain material activities of the Midstream Partnership, including material increases in capital expenditures and certain equity issuances, entering into transactions with related parties and acquiring, pledging or disposing of certain material assets. As indicated above, each of OGE and CenterPoint indirectly have 50 percent of the management rights of the general partner, and, initially, the limited partner interests of the Midstream Partnership are held by OGE (28.5 percent), CERC (58.3 percent) and Enogex Holdings (13.2 percent). The Partnership Agreement provides that transfers of any limited

partner interests will be subject to specified conditions, including, for a period of time, rights of first offer and rights of first refusal.

Prior to an initial public offering (the "IPO"), 100 percent of Distributable Cash (as defined in the Partnership Agreement), will be distributed to the limited partners each quarter. After an IPO, 100 percent of Available Cash (as defined in the Partnership Agreement) will be distributed to the limited partners each quarter. The general partner also owns incentive distribution rights that would entitle the general partner to an increasing percentage of quarterly cash distributions after specified distributions have been made to the limited partners. The Partnership Agreement also includes provisions governing the treatment of capital accounts, tax treatment and withdrawal of partners. The general partner may be removed by the vote of 75 percent of the limited partner interests.

The general partner will be governed by the terms of the Amended and Restated Limited Liability Company Agreement of CNP OGE GP LLC dated as of May 1, 2013 (the "GP Agreement"). Pursuant to the GP Agreement, each of OGEH and CERC have 50 percent of the management units of the general partner, while OGEH owns 60 percent, and CERC owns 40 percent, of the economic units of the general partner. The GP Agreement provides that, until May 1, 2016, no transfers (other than transfers to affiliates) of membership interests in the general partner will be permitted. The general partner will be managed by a board of directors made up of an equal number of representatives designated by each of CenterPoint and OGE. Actions of the board of directors generally will require majority approval. Under the terms of the GP Agreement, if the board of directors is unable to reach a majority approval, specified procedures, including potentially a separate vote of the independent directors (if any) or mediation, will be implemented to resolve the deadlock.

For further information regarding the Partnership Agreement and GP Agreement, see the agreements that are attached as Exhibit 10.01 and 10.02 and incorporated by reference herein.

Registration Rights Agreement and Omnibus Agreement

Pursuant to a Registration Rights Agreement, OGE and CenterPoint have agreed to initiate the process for the sale of an equity interest in the Midstream Partnership in an initial IPO. OGE can give no assurances that the IPO will be consummated. Prior to consummating the IPO, OGE, CenterPoint and the Midstream Partnership will need to complete the negotiation of the financial and other terms, including the initial public offering price. In addition, consummation of the IPO is subject to market conditions. For so long as Enogex Holdings maintains a minimum ownership percentage, Enogex Holdings is entitled to consult with the Midstream Partnership in connection with the IPO. The Midstream Partnership has agreed to file a registration statement for the IPO no later than May 1, 2014 and, subject to limited exceptions, consummate the IPO within 180 days of the filing of the registration statement. This report does not constitute an offer to sell or the solicitation of any offer to buy, the equity of the Midstream Partnership. Any offers or solicitations of offers to buy, or any sales of securities, will only be made in accordance with the registration requirements of the Securities Act of 1933 or an exemption therefrom.

The Registration Rights Agreement also provides that, subject to certain limitations, (i) each of CenterPoint and OGE is entitled, beginning 180 days after the IPO, and (ii) the Bronco Group is entitled, beginning on the date that the Midstream Partnership is first eligible to file a registration statement under Form S-3, to demand that the Midstream Partnership effect the registration under the Securities Act of the common units of the Midstream Partnership held by such party. In connection with the preparation and filing of any registration statement, the Midstream Partnership will bear all costs and expenses incidental to any

registration statement. Any underwriting discounts and commissions will be borne by the seller of the common units of the Midstream Partnership.

Subject to the exceptions provided below, pursuant to the terms of the Omnibus Agreement dated as of May 1, 2013 among OGE, Enogex Holdings and CenterPoint, each of OGE and CenterPoint is required to hold or otherwise conduct all of its respective Midstream Operations (as defined below) located within the United States in the Midstream Partnership. This restriction will cease to apply to both OGE and CenterPoint as soon as either OGE or CenterPoint ceases to hold (i) any interest in the general partner of the Midstream Partnership or (ii) at least 20 percent of the limited partner interests of the Midstream Partnership. "Midstream Operations" generally means, subject to certain exceptions, the gathering, compression, treatment, processing, blending, transportation, storage, isomerization and fractionation of crude oil and natural gas, its associated production water and enhanced recovery materials such as carbon dioxide, and its respective constituents and the following products: methane, natural gas liquids (Y-grade, ethane, propane, normal butane, isobutane and natural gasoline), condensate, and refined products and distillates (gasoline, refined product blendstocks, olefins, naphtha, aviation fuels, diesel, heating oil, kerosene, jet fuels, fuel oil, residual fuel oil, heavy oil, bunker fuel, cokes, and asphalts), to the extent such activities are located within the United States.

In addition, if OGE or CenterPoint acquires any assets or equity of any person engaged in Midstream Operations with a value in excess of $50 million (or $100 million in the aggregate with such party's other acquired Midstream Operations that have not been offered to the Midstream Partnership), the acquiring party will be required to offer the Midstream Partnership the opportunity to acquire such assets or equity for such value; provided, that the acquiring party will not be obligated to offer any such assets or equity to the Midstream Partnership if the acquiring party intends to cease using them in Midstream Operations within 12 months. If the Midstream Partnership does not exercise its option, then the acquiring party will be free to retain and operate such Midstream Operations; provided, however, that if the fair market value of such Midstream Operations is greater than 66 2/3 percent of the fair market value of all of the assets being acquired in such transaction, then the acquiring party will be required to dispose of such Midstream Operations within 24 months.

As long as Enogex Holdings has board observation rights, Enogex Holdings will be prohibited from pursuing any transaction independently from the Midstream Partnership (i) if Enogex Holdings' consent is required for the Midstream Partnership to pursue such transaction and (ii) Enogex Holdings affirmatively votes not to consent to such transaction.

For further information regarding the Registration Rights Agreement and the Omnibus Agreement, see the agreements that are attached as Exhibit 10.03 and 10.04 and incorporated by reference herein.

Financing Transactions

In connection with the formation of the Midstream Partnership, on May 1, 2013, the Midstream Partnership entered into a $1.05 billion 3-year senior unsecured term loan facility (the "Term Loan Facility") with Citibank, N.A., as administrative agent, UBS Securities LLC, as syndication agent, JPMorgan Chase Bank, N.A. ("JPMCB") and Wells Fargo Bank, National Association ("Wells Fargo") as co-documentation agents, and the several lenders thereto. The proceeds of the loans advanced pursuant to the Term Loan Facility were used to repay $1.05 billion of intercompany indebtedness owed to CERC by a predecessor entity of the Midstream Partnership. CERC has guaranteed collection (not payment) of the Midstream Partnership's obligations under the Term Loan Facility, which guarantee is subordinated to all senior debt of CERC.

On May 1, 2013, the Midstream Partnership also entered into a $1.4 billion five year senior unsecured revolving credit facility (the "Revolving Credit Facility") with Citibank, N.A., as administrative agent, UBS Securities LLC, as syndication agent, JPMCB and Wells Fargo, as co documentation agents, the lenders from time to time party thereto and the letter of credit issuers from time to time party thereto. Under certain circumstances, the Revolving Credit Facility may be increased from time to time up to an additional $700 million, in aggregate.

The Term Loan Facility and the Revolving Credit Facility each permits outstanding borrowings to bear interest at the eurodollar rate and/or an alternate base rate, at the Midstream Partnership's election, plus an applicable margin based on the Midstream Partnership's credit ratings. The applicable margin will be, (1) in the case of interest rates determined by reference to the eurodollar rate, between 1.25% and 2.00% per annum and (2) in the case of interest rates determined by reference to the alternate base rate, between 0.25% and 1.00% per annum. As of May 7, 2013, the applicable margin for eurodollar-based borrowings under the Term Loan Facility and the Revolving Credit Facility was 1.625% based on the Midstream Partnership's credit ratings. As of May 7, 2013, the applicable margin for alternate base rate-based borrowings under the Term Loan Facility and the Revolving Credit Facility was 0.625% based on the Midstream Partnership's credit ratings. For borrowings under each of the Term Loan Facility and the Revolving Credit Facility, the eurodollar rate will be fixed for interest periods of 1, 2, 3, or 6 months, at the Midstream Partnership's election, or if requested by Midstream Partnership such other period as agreed to by all of the lenders. The base rate will fluctuate.

In addition, the Revolving Credit Facility requires the Midstream Partnership to pay a fee on unused commitments. The fee will range from 0.15% to 0.35% per annum depending upon the Midstream Partnership's credit ratings. As of May 7, 2013, the commitment fee under the Revolving Credit Facility was 0.25% per annum based on the Midstream Partnership's credit ratings.

Advances under the Revolving Credit Facility are subject to certain conditions precedent, including the accuracy in all material respects of certain representations and warranties and the absence of any default or event of default. The Revolving Credit Facility provides for issuance of letters of credit of up to $400 million dollars at any time outstanding. On May 1, 2013, advances under the Revolving Credit Facility were used to refinance Enogex's revolving credit facility described below and existing indebtedness owing by Enogex to OGE as of May 1, 2013 and for general corporate purposes. As of May 1, 2013, there was approximately $107,100,000 in principal advances and approximately $2,000,000 in letters of credit outstanding under the Revolving Credit Facility.

The Term Loan Facility and the Revolving Credit Facility each contains a financial covenant requiring the Midstream Partnership to maintain a ratio of consolidated funded debt to consolidated earnings before interest, taxes, depreciation and amortization ("EBITDA") as of the last day of each fiscal quarter of less than or equal to 5.00 to 1.00; provided that, for a certain period of time following the consummation by the Midstream Partnership or certain of its subsidiaries or one or more related acquisitions with a purchase price of at least $50 million in the aggregate, the consolidated funded debt to EBITDA ratio as of the last day of each such fiscal quarter during such period would be permitted to be up to 5.50 to 1.00.

The Term Loan Facility and the Revolving Credit Facility also contain covenants that restrict the Midstream Partnership and certain subsidiaries in respect of, among other things, mergers and consolidations, sales of all or substantially all assets, incurrence of subsidiary indebtedness, incurrence of liens, transactions with affiliates, designation of subsidiaries as Excluded Subsidiaries (as defined in the Term Loan Facility and the Revolving Credit Facility), restricted payments, changes in the nature of their respective businesses and entering into certain restrictive agreements. The Term Loan Facility and the Revolving Credit Facility

are each subject to acceleration upon the occurrence of certain defaults, including, among others, payment defaults on such facility, breach of representations, warranties and covenants, acceleration of indebtedness (other than intercompany) of $100 million or more in the aggregate, change of control, nonpayment of uninsured money judgments in excess of $100 million, and the occurrence of certain ERISA and bankruptcy events, subject where applicable to specified cure periods.

On May 1, 2013, Enogex LLC terminated its $400 million revolving credit agreement dated December 13, 2011 with Wells Fargo Bank, National Association, as agent, and the other lenders from time to time party thereto.

For further information regarding the terms of the Term Loan Facility and the Revolving Credit Facility, see the credit agreements that are attached as Exhibit 99.01 and 99.02 and incorporated by reference herein.

The MFA is filed as an exhibit to this Current Report on Form 8-K to provide investors and security holders with information regarding its terms. It is not intended to provide any other factual information about the Midstream Partnership, OGE, the Bronco Group or CenterPoint or any of their respective affiliates or businesses. The representations, warranties, covenants and agreements contained in the MFA were made only for the purposes of such agreement and as of specified dates, were solely for the benefit of the parties to such agreement, and may be subject to limitations agreed upon by the contracting parties. The representations and warranties may have been made for the purposes of allocating contractual risk between the parties to the MFA instead of establishing these matters as facts, and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors. Investors and security holders are not third-party beneficiaries under the MFA and should not rely on the representations, warranties, covenants and agreements or any descriptions thereof as characterizations of the actual state of facts or condition of the Midstream Partnership, OGE, the Bronco Group or CenterPoint or any of their respective affiliates or businesses. Moreover, the assertions embodied in the representations and warranties contained in the MFA are qualified by information in disclosure letters that the parties have exchanged. Accordingly, investors and security holders should not rely on the representations and warranties as characterizations of the actual state of facts of the Midstream Partnership, OGE, the Bronco Group or CenterPoint or any of their respective affiliates or businesses. Information concerning the subject matter of the representations and warranties may change after the date of the MFA, which subsequent information may or may not be fully reflected in OGE's public disclosures.

The foregoing descriptions of the MFA, the agreements related thereto (including the Partnership Agreement, the GP Agreement, the Registration Rights Agreement and the Omnibus Agreement), the Term Loan and the Revolving Credit Facility are only summaries, do not purport to be complete and are qualified in their entirety by reference to the full text of such documents, which are filed as exhibits hereto and incorporated herein by reference.

Forward-Looking Statements

This filing contains forward-looking statements, which are subject to risks, uncertainties, assumptions and other factors that are difficult to predict and that could cause actual results to vary materially from those expressed in or indicated by them. Factors that could cause actual results to differ materially include, but are not limited to (1) the inability to consummate the proposed IPO in a timely manner or at all; (2) risks that the transaction disrupts current plans and operations of OGE; (3) potential difficulties in employee retention as a result of the transaction; (4) the ability to recognize the benefits of the transaction; and (5) other factors described in OGE's filings with the Securities and Exchange Commission. Many of the factors that will

determine the outcome of the subject matter of this filing are beyond the ability of OGE to control or predict. OGE can give no assurance that the conditions to transaction will be satisfied. Except as required by law, OGE undertake no obligation to revise or update any forward-looking statement, or to make any other forward-looking statements, whether as a result of new information, future events or otherwise.

OF LIMITED PARTNERSHIP OF CENTERPOINT ENERGY FIELD SERVICES LP

THIS FIRST AMENDED AND RESTATED AGREEMENT OF LIMITED PARTNERSHIP OF CENTERPOINT ENERGY FIELD SERVICES LP, dated as of May 1, 2013, is entered into by and among CNP OGE GP LLC, a Delaware limited liability company, as the General Partner, CenterPoint Energy Resources Corp., a Delaware corporation (“CERC”), OGE Enogex Holdings LLC, a Delaware limited liability company (“OGEH”), and Enogex Holdings LLC, a Delaware limited liability company (“Bronco”), together with any other Persons who become Partners in the Partnership or parties hereto as provided herein. In consideration of the covenants, conditions and agreements contained herein, the parties hereto hereby agree as follows:

ARTICLE I

DEFINITIONS

Section 1.1    Definitions. The following definitions shall be for all purposes, unless otherwise clearly indicated to the contrary, applied to the terms used in this Agreement.

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

“Additional Book Basis” means the portion of any remaining Carrying Value of an Adjusted Property that is attributable to positive adjustments made to such Carrying Value as a result of Book-Up Events. For purposes of determining the extent that Carrying Value constitutes Additional Book Basis:

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

(b)If Carrying Value that constitutes Additional Book Basis is reduced as a result of a Book-Down Event and the Carrying Value of other property is increased as a result of such Book-Down Event, an allocable portion of any such increase in Carrying Value shall be treated as Additional Book Basis; provided, that the amount treated as Additional Book Basis pursuant hereto as a result of such Book-Down Event shall not exceed the amount by which the Aggregate Remaining Net Positive Adjustments after such Book-Down Event exceeds the remaining Additional Book Basis attributable to all of the Partnership's Adjusted Property after

1

such Book-Down Event (determined without regard to the application of this clause (b) to such Book-Down Event).

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

“AdjustedAvailable Cash” means, with respect to any Quarter commencing prior to the IPO Closing Date and ending prior to the Liquidation Date:

(a)EBITDA with respect to such Quarter, less

(b)maintenance capital expenditures incurred with respect to such Quarter in the ordinary course of business of the Partnership Group as required to replace, repair or maintain existing assets of the Partnership Group, including those capital expenditures associated with system integrity, reliability, security, computer software and hardware, and governmental compliance, less

(c)Consolidated Interest Expense with respect to such Quarter.

Notwithstanding the foregoing, “Adjusted Available Cash” with respect to the Quarter in which the Liquidation Date occurs and any subsequent Quarter shall equal zero.

“Adjusted Capital Account” means the Capital Account maintained for each Partner as of the end of each taxable period of the Partnership, (a) increased by any amounts that such Partner is obligated to restore under the standards set by Treasury Regulation Section 1.704-1(b)(2)(ii)(c) (or is deemed obligated to restore under Treasury Regulation Sections 1.704-2(g) and 1.704-2(i)(5)) and (b) decreased by (i) the amount of all losses and deductions that, as of the end of such taxable period, are reasonably expected to be allocated to such Partner in subsequent taxable periods under Sections 704(e)(2) and 706(d) of the Code and Treasury Regulation Section 1.751-1(b)(2)(ii), and (ii) the amount of all distributions that, as of the end of such taxable period, are reasonably expected to be made to such Partner in subsequent taxable periods in accordance with the terms of this Agreement or otherwise to the extent they exceed offsetting increases to such Partner's Capital Account that are reasonably expected to occur during (or prior to) the taxable period in which such distributions are reasonably expected to be made (other than increases as a result of a minimum gain chargeback pursuant to Section 6.1(d)(i) or 6.1(d)(ii)). The foregoing definition of Adjusted Capital Account is intended to comply with the provisions of Treasury Regulation Section 1.704-1(b)(2)(ii)(d) and shall be interpreted consistently therewith. The “Adjusted Capital Account” of a Partner in respect of any Partnership Interest

2

shall be the amount that such Adjusted Capital Account would be if such Partnership Interest were the only interest in the Partnership held by such Partner from and after the date on which such Partnership Interest was first issued.

“Adjusted Operating Surplus” means, with respect to any period, (a) Operating Surplus generated with respect to such period less (b)(i) the amount of any net increase in Working Capital Borrowings (or the Partnership's proportionate share of any net increase in Working Capital Borrowings in the case of Subsidiaries that are not wholly owned) with respect to such period and (ii) the amount of any net decrease in cash reserves (or the Partnership's proportionate share of any net decrease in cash reserves in the case of Subsidiaries that are not wholly owned) for Operating Expenditures with respect to such period not relating to an Operating Expenditure made with respect to such period, and plus (c) (i) the amount of any net decrease in Working Capital Borrowings (or the Partnership's proportionate share of any net decrease in Working Capital Borrowings in the case of Subsidiaries that are not wholly owned) with respect to such period, (ii) the amount of any net decrease made in subsequent periods in cash reserves for Operating Expenditures initially established with respect to such period to the extent such decrease results in a reduction in Adjusted Operating Surplus in subsequent periods pursuant to clause (b)(ii) above and (iii) the amount of any net increase in cash reserves (or the Partnership's proportionate share of any net increase in cash reserves in the case of Subsidiaries that are not wholly owned) for Operating Expenditures with respect to such period required by any debt instrument for the repayment of principal, interest or premium. Adjusted Operating Surplus does not include that portion of Operating Surplus included in clause (a)(i) of the definition of Operating Surplus.

Notwithstanding anything in the foregoing to the contrary, CERC and its Affiliates (other than the General Partner or any Group Member), on the one hand, and OGEH and its Affiliates (other than the General Partner or any Group Member), on the other hand, will not be deemed to be Affiliates of one another hereunder unless there is a basis for such Affiliation independent of their respective Affiliation with any Group Member, the General Partner or any Affiliate (disregarding the immediately preceding sentence) of any Group Member or the General Partner.

Any approval by Bronco pursuant to this Section 3.4(a) shall be evidenced in writing executed by a senior executive officer of Bronco. Any such approval by Bronco pursuant to any subsection of this Section 3.4(a) shall be deemed an approval for purposes of all subsections of this Section 3.4(a). A failure by Bronco to object in writing within ten (10) Business Days of receipt of written notice from the General Partner to any matter that requires consent pursuant to this Section 3.4(a) will be deemed to be an approval by Bronco of such matter. At any time prior to the Bronco Fall-Away Date, if Bronco timely objects in writing to a potential transaction, agreement, arrangement or other matter involving any Group Member that requires consent pursuant to this Section 3.4(a), then neither Bronco nor any of its Affiliates may pursue such transaction, agreement, arrangement or other matter independently. If Bronco approves such transaction, agreement, arrangement or other matter, or abstains from consenting to such transaction, agreement, arrangement or other matter, then Bronco and its Affiliates will not be restricted from pursuing such transaction, agreement, arrangement or other matter independently from the Partnership Group; provided, however, that (1) Bronco shall abstain from consenting or objecting to any transaction, agreement, arrangement or other matter with respect to which any Person (other than a Group Member) in which Bronco or a Bronco Affiliate has any economic

37

interest, is pursuing or is involved in or, to Bronco's knowledge, is considering pursuing or becoming involved in, and (2) Bronco shall treat any and all information that it receives in connection with its rights under Section 3.4(a), whether written or oral, as Confidential Information as defined in, and in accordance with the terms of, the Omnibus Agreement.

(b)Bronco shall have the right to (x) designate two individuals who are employees of Bronco or its Affiliates (each such individual, an “Observer”), and one alternate Observer to serve in place of either of the principal Observers, to receive notice (which notice will be delivered to the Observers on the same date such notice is delivered to the members of the Board of Directors) of and attend meetings of the Board of Directors in an observer capacity and (y) receive copies of information routinely provided to the members of the Board of Directors; provided that the failure of the General Partner to give any such notice or documents or information to Bronco or an Observer shall not affect the validity of any action taken by the General Partner or the Board of Directors. Bronco's rights set forth above shall be subject to the following terms and conditions:

(i)Bronco agrees to treat any and all such information, whether written or oral, as Confidential Information as defined in, and in accordance with the terms of, the Omnibus Agreement;

(ii)If the Board of Directors (A) has been advised by legal counsel to the Partnership that the withholding of certain written materials from the Observers or the exclusion of the Observers from attendance at certain portions of a board meeting is necessary for the protection of the attorney-client privilege for the benefit of the Partnership with respect to a matter in which the Partnership is involved, and the Board of Directors notifies the Observers as soon as practical after becoming aware of such advice of the circumstances giving rise to the need to protect such attorney-client privilege or (B) will be considering at such board meeting (and in connection therewith receiving materials regarding) a transaction, agreement, arrangement or other matter with respect to which a Person (other than a Group Member) in which Bronco or a Bronco Affiliate has an economic interest, is pursuing or is involved in, then, at the election of a majority of the Board of Directors, (x) such written materials may be redacted or withheld from Bronco and the Observers, or (y) the Observers may be excluded from such portions of the board meetings or committee meetings, in each case, only to the extent necessary to protect such attorney-client privilege or related to such matter (as the case may be);

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

(iv)The reasonable costs and expenses incurred by the Observers in connection with any meeting of the Board of Directors shall be borne and paid by the General Partner (and any Observer may obtain reimbursement from the General Partner for any such reasonably documented costs and expenses).

38

(v)The initial Observers shall be Robb Turner and Eric Lammers, and Michael Christopher shall be the initial alternate Observer. Bronco may change its designated Observers or alternate Observer from time to time by providing notice to the General Partner thereof, which change shall be subject to the General Partner's approval thereof (such approval not to be unreasonably withheld, conditioned or delayed).

(c)No General Partner Membership Interest may be “transferred” (as such term is defined in the General Partner LLC Agreement), in whole or in part, other than to an Affiliate, without the written consent of Bronco (such consent not to be unreasonably withheld, conditioned or delayed).

(d)For the avoidance of doubt, so long as EH II is a Group Member, the General Partner shall not, in its capacity as a holder of the EH Management Units, cause EH II to take any action that the General Partner would otherwise be prohibited from causing EH II (as a Group Member) to take pursuant to Section 3.4(a).

(e)In the event the General Partner elects not to cause the Partnership to pursue any claim for indemnification that the Partnership is entitled to pursue under any agreement or arrangement (including this Agreement) between any Group Member, on the one hand, and the General Partner, any Sponsor Party or any Affiliate of the General Partner or any Sponsor Party (other than a Group Member), on the other hand (such party, an “Indemnitor”) that could result in the payment of any amount by the Indemnitor, Bronco shall have the right to cause the General Partner to cause the Partnership to pursue such claim by delivering written notice of Bronco's election to the General Partner until the Bronco Fall-Away Date. Promptly following the receipt by the General Partner of Bronco's written election pursuant to the foregoing sentence, the Partnership will provide notice thereof in writing to the applicable Indemnitor, specifying the nature of and specific basis for such claim, and the General Partner shall thereafter cause the Partnership to diligently pursue such claim in accordance with the applicable indemnification provisions of such agreement or arrangement. If the Partnership fails to provide such notice to the Indemnitor within ten (10) Business Days or if the Partnership fails to diligently pursue such claim in accordance with this Section 3.4(e), then Bronco may notify the Indemnitor of such claim directly and may control the pursuit of such claim against the Indemnitor on behalf of the Partnership. Both Sponsor Parties agree to cause their designated members of the Board of Directors of the General Partner to approve the actions reasonably requested by Bronco with respect to any such claim.

ARTICLE IV

CERTIFICATES; RECORD HOLDERS; TRANSFER OF PARTNERSHIP INTERESTS; REDEMPTION OF PARTNERSHIP INTERESTS

Section 4.1    Certificates. Owners of Partnership Interests and, where appropriate, Derivative Partnership Interests, shall be recorded in the Register and ownership of such interests shall be evidenced by a physical certificate or book entry notation in the Register. Notwithstanding anything to the contrary in this Agreement, unless the General Partner shall determine otherwise in respect of some or all of any or all classes of Partnership Interests and Derivative Partnership Interests, Partnership Interests and Derivative Partnership Interests shall

39

not be evidenced by physical certificates. Certificates, if any, shall be executed on behalf of the Partnership by the Chief Executive Officer, President, Chief Financial Officer or any Vice President and the Secretary, any Assistant Secretary, or other authorized officer of the General Partner, and shall bear the legend set forth in Section 4.8(g). The signatures of such officers upon a certificate may be facsimiles. In case any officer who has signed or whose signature has been placed upon such certificate shall have ceased to be such officer before such certificate is issued, it may be issued by the Partnership with the same effect as if he were such officer at the date of its issuance. If a Transfer Agent has been appointed for a class of Partnership Interests, no Certificate for such class of Partnership Interests shall be valid for any purpose until it has been countersigned by the Transfer Agent; provided, however, that, if the General Partner elects to cause the Partnership to issue Partnership Interests of such class in global form, the Certificate shall be valid upon receipt of a certificate from the Transfer Agent certifying that the Partnership Interests have been duly registered in accordance with the directions of the Partnership. Subject to the requirements of Section 6.8(b) and Section 6.8(c), if Common Units are evidenced by Certificates, on or after the date on which Subordinated Units are converted into Common Units pursuant to the terms of Section 5.8, the Record Holders of such Subordinated Units (i) if the Subordinated Units are evidenced by Certificates, may exchange such Certificates for Certificates evidencing the Common Units into which such Record Holder's Subordinated Units converted, or (ii) if the Subordinated Units are not evidenced by Certificates, shall be issued Certificates evidencing the Common Units into which such Record Holders' Subordinated Units converted. With respect to any Partnership Interests that are represented by physical certificates, the General Partner may determine that such Partnership Interests will no longer be represented by physical certificates and may, upon written notice to the holders of such Partnership Interests and subject to applicable law, take whatever actions it deems necessary or appropriate to cause such Partnership Interests to be registered in book entry or global form and may cause such physical certificates to be cancelled or deemed cancelled.

Section 4.2    Mutilated, Destroyed, Lost or Stolen Certificates.

(a)If any mutilated Certificate is surrendered to the Transfer Agent, the appropriate officers of the General Partner on behalf of the Partnership shall execute, and the Transfer Agent shall countersign and deliver in exchange therefor, a new Certificate evidencing the same number and type of Partnership Interests or Derivative Partnership Interests as the Certificate so surrendered.

(b)The appropriate officers of the General Partner on behalf of the Partnership shall execute and deliver, and the Transfer Agent shall countersign, a new Certificate in place of any Certificate previously issued, if the Record Holder of the Certificate:

(i)makes proof by affidavit, in form and substance satisfactory to the General Partner, that a previously issued Certificate has been lost, destroyed or stolen;

(ii)requests the issuance of a new Certificate before the General Partner has notice that the Certificate has been acquired by a purchaser for value in good faith and without notice of an adverse claim;

40

(iii)if requested by the General Partner, delivers to the General Partner a bond, in form and substance satisfactory to the General Partner, with surety or sureties and with fixed or open penalty as the General Partner may direct to indemnify the Partnership, the Partners, the General Partner and the Transfer Agent against any claim that may be made on account of the alleged loss, destruction or theft of the Certificate; and

(iv)satisfies any other reasonable requirements imposed by the General Partner or the Transfer Agent.

If a Limited Partner fails to notify the General Partner within a reasonable period of time after such Limited Partner has notice of the loss, destruction or theft of a Certificate, and a transfer of the Limited Partner Interests represented by the Certificate is registered before the Partnership, the General Partner or the Transfer Agent receives such notification, to the fullest extent permitted by law, the Limited Partner shall be precluded from making any claim against the Partnership, the General Partner or the Transfer Agent for such transfer or for a new Certificate.

(c)As a condition to the issuance of any new Certificate under this Section 4.2, the General Partner may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Transfer Agent) reasonably connected therewith.

Section 4.3    Record Holders. The names and addresses of Unitholders as they appear in the Register shall be the official list of Record Holders of the Partnership Interests for all purposes. The Partnership and the General Partner shall be entitled to recognize the Record Holder as the Partner with respect to any Partnership Interest and, accordingly, shall not be bound to recognize any equitable or other claim to, or interest in, such Partnership Interest on the part of any other Person or Group, regardless of whether the Partnership or the General Partner shall have actual or other notice thereof, except as otherwise provided by law or any applicable rule, regulation, guideline or requirement of any National Securities Exchange on which such Partnership Interests are listed or admitted to trading. Without limiting the foregoing, when a Person (such as a broker, dealer, bank, trust company or clearing corporation or an agent of any of the foregoing) is acting as nominee, agent or in some other representative capacity for another Person or Group in acquiring and/or holding Partnership Interests, as between the Partnership on the one hand, and such other Person on the other, such representative Person shall be the Limited Partner with respect to such Partnership Interest upon becoming the Record Holder in accordance with Section 10.1(b) and have the rights and obligations of a Partner hereunder as, and to the extent, provided herein, including Section 10.1(c).

Section 4.4    Transfer Generally.

(a)The term “transfer,” when used in this Agreement with respect to a Partnership Interest, shall mean a transaction (i) by which the General Partner assigns its General Partner Interest to another Person or by which a holder of Incentive Distribution Rights assigns its Incentive Distribution Rights to another Person, and includes a transfer, sale, assignment, gift, Encumbrance, hypothecation, exchange or any other disposition by law or otherwise or (ii) by which the holder of a Limited Partner Interest (other than an Incentive Distribution Right) makes

41

any direct or indirect transfer, sale, assignment, gift, Encumbrance, hypothecation, exchange or any other disposition by law or otherwise and, without limiting the generality of the foregoing, any distribution, transfer, assignment or other disposition of any Limited Partner Interest, whether voluntary, involuntary or pursuant to any dissolution, liquidation or termination of such Person, to such Person's members, stockholders, partners or other interestholders shall constitute a “transfer” of a Limited Partner Interest (for the avoidance of doubt, with respect to a Limited Partner, any transfer, sale, assignment, gift, Encumbrance, hypothecation, exchange or other disposition of any interest in such Limited Partner, by such Limited Partner or any interestholder of such Limited Partner shall be deemed to be an indirect Transfer of a Limited Partner Interest hereunder); provided, however, that any transfer of all or substantially all the assets, or a Change in Control, of CNP or OGE shall not be a “transfer” hereunder.

(b)No Partnership Interest shall be transferred, in whole or in part, except in accordance with the terms and conditions set forth in this Article IV. Any transfer or purported transfer of a Partnership Interest not made in accordance with this Article IV shall be null and void, and the Partnership shall have no obligation to effect or recognize any such transfer or purported transfer. Except as provided in Section 4.8(f), notwithstanding the other provisions of this Article IV, prior to the IPO Closing Date, no transfer of any Partnership Interests shall be made if such transfer would (i) violate the then applicable federal or state securities laws or rules and regulations of the Commission, any state securities commission or any other governmental authority with jurisdiction over such transfer, (ii) terminate the existence or qualification of the Partnership under the laws of the jurisdiction of its formation, (iii) cause the Partnership to be treated as an association taxable as a corporation or otherwise to be taxed as an entity for federal income tax purposes (to the extent not already so treated or taxed), or (iv) with respect to transfers by Partners other than Bronco prior to the IPO Closing Date, constitute a breach or violation of, or a change of control or event of default under, any credit agreement, loan agreement, indenture, mortgage, deed of trust or other similar instrument or document governing indebtedness for borrowed money of the Partnership or any Group Member. The Partnership may issue stop transfer instructions to any Transfer Agent in order to implement any restriction on transfer contemplated by this Agreement.

(c)Subject to Section 3.4(c), nothing contained in this Agreement shall be construed to prevent or limit a disposition by any stockholder, member, partner or other owner of the General Partner of any or all of the shares of stock, membership interests, partnership interests or other ownership interests in the General Partner and the term “transfer” shall not include any such disposition.

Section 4.5    Registration and Transfer of Limited Partner Interests.

(a)The General Partner shall keep, or cause to be kept by the Transfer Agent on behalf of the Partnership, one or more registers in which, subject to such reasonable regulations as it may prescribe and subject to the provisions of Section 4.5(b), the registration and transfer of Limited Partner Interests, and any Derivative Partnership Interests as applicable, shall be recorded (the “Register”).

(b)The General Partner shall not recognize any transfer of Limited Partner Interests evidenced by Certificates until the Certificates evidencing such Limited Partner Interests are

42

surrendered for registration of transfer. No charge shall be imposed by the General Partner for such transfer; provided, that as a condition to the issuance of any new Certificate under this Section 4.5, the General Partner may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed with respect thereto and any other expenses (including the fees and expenses of the Transfer Agent) reasonably connected therewith. Upon surrender of a Certificate for registration of transfer of any Limited Partner Interests evidenced by a Certificate, and subject to the provisions of this Section 4.5(b), the appropriate officers of the General Partner on behalf of the Partnership shall execute and deliver, and in the case of Certificates evidencing Limited Partner Interests for which a Transfer Agent has been appointed, the Transfer Agent shall countersign and deliver, in the name of the holder or the designated transferee or transferees, as required pursuant to the holder's instructions, one or more new Certificates evidencing the same aggregate number and type of Limited Partner Interests as was evidenced by the Certificate so surrendered. Upon the proper surrender of a Certificate, such transfer shall be recorded in the Register.

(c)Except as provided in Section 4.9, by acceptance of any Limited Partner Interests pursuant to a transfer in accordance with this Article IV, each transferee of a Limited Partner Interest (including any nominee, or agent or representative acquiring such Limited Partner Interests for the account of another Person or Group) (i) shall be admitted to the Partnership as a Limited Partner with respect to the Limited Partner Interests so transferred to such Person when any such transfer or admission is reflected in the Register and such Person becomes the Record Holder of the Limited Partner Interests so transferred, (ii) shall become bound, and shall be deemed to have agreed to be bound, by the terms of this Agreement, (iii) shall be deemed to represent that the transferee has the capacity, power and authority to enter into this Agreement and (iv) shall be deemed to make any consents, acknowledgements or waivers contained in this Agreement, all with or without execution of this Agreement by such Person. The transfer of any Limited Partner Interests and the admission of any new Limited Partner shall not constitute an amendment to this Agreement.

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

(e)If at any time a Person (other than a Limited Partner pursuant to the terms of Section 4.11 or Section 4.12) acquires a majority of the Common Units held by Bronco at the time of such transfer, including at least the Initial Bronco Amount (a “Bronco Successor”), then such Bronco Successor shall succeed to all of Bronco's rights and obligations provided in Section 3.4, Section 4.6(b) and Section 4.6(d), as though such Bronco Successor were Bronco thereunder, and Bronco shall no longer be entitled to exercise any of Bronco's rights and obligations in Section 3.4, Section 4.6(b) and Section 4.6(d) regardless of the number of Common Units Bronco continues to hold; provided, however, that any Bronco Successor that, at the time of such transfer, is a Midstream Successor shall not succeed to any of Bronco's rights under Section 3.4 or this Section 4.5(e).

43

(f)If at any time Bronco is controlled by a Midstream Successor, then Bronco shall not be entitled to exercise any of Bronco's rights under Section 3.4, Section 4.6(b) or Section 4.6(d) regardless of the number of Common Units Bronco continues to hold, but only for so long as such Midstream Successor remains in control of Bronco. As used in this Section 4.5(f), the term “control” means the possession, direct or indirect, of the power to direct or cause the direction of the management and policies of Bronco, whether through ownership of Voting Securities, by contract or otherwise.

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

(a)Subject to Section 4.6(b) and (c), the General Partner may at its option transfer all or any part of its General Partner Interest without Unitholder approval or the approval of the holders of the Incentive Distribution Rights.

(b)Subject to Section 4.6(c), the General Partner shall not transfer all or any part of its General Partner Interest to any Person without the prior approval of (i) all members of the Board of Directors and (ii) prior to the Bronco Fall-Away Date, Bronco.

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

(d)The General Partner shall not transfer all or any EH Management Units to any Person without the prior approval of (i) all members of the Board of Directors and (ii) prior to the Bronco Fall-Away Date, Bronco; provided, that the General Partner shall transfer all of the EH Management Units to any successor General Partner elected in accordance with the terms of this Agreement as a condition to the election of such successor.

Section 4.7    Transfer of Incentive Distribution Rights. The General Partner or any other holder of Incentive Distribution Rights may transfer any or all of its Incentive Distribution Rights without Unitholder approval.

Section 4.8    Restrictions on Transfers of Limited Partner Interests.

(a)Except for a Permitted Transfer or as provided in Section 4.11(d) or Section 4.12(d), no Common Units or Subordinated Units may be transferred, in whole or in

44

part, unless the Limited Partner purporting to transfer such Common Units or Subordinated Units first complies with the applicable provisions of Sections 4.11 and 4.12. Prior to the earlier of the IPO Closing Date and the date that is 18 months following the Closing Date, except for a Permitted Transfer or a transfer in connection with an Initial Public Offering, no Limited Partner Interest may be transferred, in whole or in part, without the prior approval of a majority of the members of the Board of Directors, including the affirmative votes of one member appointed by CERC and one member appointed by OGEH. Notwithstanding the foregoing, any transfer of the direct or indirect equity ownership interests of Bronco by the respective holders thereof (an “Upstream Transfer”) shall be permitted, shall not require the consent of the Board of Directors and shall not be subject to Sections 4.11 and 4.12; provided, however, that no Upstream Transfer shall be made prior to the earlier of the IPO Closing Date and the date that is 18 months following the Closing Date if it would result in Bronco ceasing to be a member of the ArcLight Group.

(b)From the execution hereof until the IPO Closing Date, no transfer (including a Permitted Transfer) of a Limited Partner Interest may be undertaken unless and until the following have occurred: (i) the proposed transferee shall have agreed in writing to be bound by the terms of this Agreement and provided to the Partnership its name, address, taxpayer identification number and any other information reasonably necessary to permit the Partnership to file all required federal and state tax returns or reasonably requested by the Board of Directors, and (ii) the Limited Partner proposing to make such transfer shall have delivered to the Partnership an Opinion of Counsel (reasonably acceptable as to form, substance and identity of counsel to the Partnership) that no registration under the Securities Act is required in connection with such transfer (unless the requirement of an opinion is waived by the Board of Directors).

(c)From the execution hereof until the IPO Closing Date, each Limited Partner making a transfer of a Limited Partner Interest shall be obligated to pay its own expenses incurred in connection with such transfer, and the Partnership shall not have any obligation with respect thereto. Each Limited Partner making a transfer shall pay, or reimburse the Partnership for, all reasonable costs and expenses incurred by the Partnership in connection with such transfer and the admission of the transferee as a Limited Partner, including the legal fees incurred in connection with the legal opinions referred to in Section 4.8(b).

(d)The General Partner may impose restrictions on the transfer of Partnership Interests if it receives an Opinion of Counsel that such restrictions are necessary to (i) avoid a significant risk of the Partnership becoming taxable as a corporation or otherwise becoming taxable as an entity for federal income tax purposes (to the extent not already so treated or taxed) or (ii) preserve the uniformity of the Limited Partner Interests (or any class or classes thereof). The General Partner may impose such restrictions by amending this Agreement, subject to Section 3.4(a); provided, however, that any amendment that would result in the delisting or suspension of trading of any class of Limited Partner Interests on the principal National Securities Exchange on which such class of Limited Partner Interests is then listed or admitted to trading must be approved, prior to such amendment being effected, by the holders of at least a majority of the Outstanding Limited Partner Interests of such class.

45

(e)The transfer of a Subordinated Unit or a Common Unit issued upon conversion of a Subordinated Unit shall be subject to the restrictions imposed by Section 6.8(b) and Section 6.8(c).

(f)Nothing contained in this Article IV, or elsewhere in this Agreement, shall preclude the settlement of any transactions involving Partnership Interests entered into through the facilities of any National Securities Exchange on which such Partnership Interests are listed or admitted to trading.

(g)Each certificate or book-entry evidencing Partnership Interests shall bear a conspicuous legend in substantially the following form:

THE HOLDER OF THIS SECURITY ACKNOWLEDGES FOR THE BENEFIT OF CENTERPOINT ENERGY FIELD SERVICES LP THAT THIS SECURITY MAY NOT BE SOLD, OFFERED, RESOLD, PLEDGED OR OTHERWISE TRANSFERRED IF SUCH TRANSFER WOULD (A) VIOLATE THE THEN APPLICABLE FEDERAL OR STATE SECURITIES LAWS OR RULES AND REGULATIONS OF THE SECURITIES AND EXCHANGE COMMISSION, ANY STATE SECURITIES COMMISSION OR ANY OTHER GOVERNMENTAL AUTHORITY WITH JURISDICTION OVER SUCH TRANSFER, (B) TERMINATE THE EXISTENCE OR QUALIFICATION OF CENTERPOINT ENERGY FIELD SERVICES LP UNDER THE LAWS OF THE STATE OF DELAWARE, OR (C) CAUSE CENTERPOINT ENERGY FIELD SERVICES LP TO BE TREATED AS AN ASSOCIATION TAXABLE AS A CORPORATION OR OTHERWISE TO BE TAXED AS AN ENTITY FOR FEDERAL INCOME TAX PURPOSES (TO THE EXTENT NOT ALREADY SO TREATED OR TAXED). CNP OGE GP LLC, THE GENERAL PARTNER OF CENTERPOINT ENERGY FIELD SERVICES LP, MAY IMPOSE ADDITIONAL RESTRICTIONS ON THE TRANSFER OF THIS SECURITY IF IT RECEIVES AN OPINION OF COUNSEL THAT SUCH RESTRICTIONS ARE NECESSARY TO (A) AVOID A SIGNIFICANT RISK OF CENTERPOINT ENERGY FIELD SERVICES LP BECOMING TAXABLE AS A CORPORATION OR OTHERWISE BECOMING TAXABLE AS AN ENTITY FOR FEDERAL INCOME TAX PURPOSES OR (B) IN THE CASE OF LIMITED PARTNER INTERESTS, TO PRESERVE THE UNIFORMITY THEREOF (OR ANY CLASS OR CLASSES OF LIMITED PARTNER INTERESTS). THIS SECURITY MAY BE SUBJECT TO ADDITIONAL RESTRICTIONS ON ITS TRANSFER PROVIDED IN THE PARTNERSHIP AGREEMENT. COPIES OF SUCH AGREEMENT MAY BE OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY THE HOLDER OF RECORD OF THIS SECURITY TO THE SECRETARY OF THE GENERAL PARTNER AT THE PRINCIPAL OFFICE OF THE PARTNERSHIP. THE RESTRICTIONS SET FORTH ABOVE SHALL NOT PRECLUDE THE SETTLEMENT OF ANY TRANSACTIONS INVOLVING THIS SECURITY ENTERED INTO THROUGH THE FACILITIES OF ANY NATIONAL SECURITIES EXCHANGE ON WHICH THIS SECURITY IS LISTED OR ADMITTED TO TRADING.

Section 4.9    Eligibility Certifications; Ineligible Holders.

(a)If at any time after the IPO Closing Date the General Partner determines, with the advice of counsel, that:

46

(i)the U.S. federal income tax status (or lack of proof of the U.S. federal income tax status) of one or more Limited Partners has or is reasonably likely to have a material adverse effect on the rates that can be charged to customers by any Group Member on assets that are subject to regulation by the FERC or an analogous regulatory body (a “Rate Eligibility Trigger”); or

(ii)any Group Member is subject to any federal, state or local law or regulation that would create a substantial risk of cancellation or forfeiture of any property in which the Group Member has an interest based on the nationality, citizenship or other related status of one or more Limited Partners (a “Citizenship Eligibility Trigger”);

then, (x) in the case of a Rate Eligibility Trigger, the General Partner may obtain such proof of the U.S. federal income tax status of the Limited Partners and, to the extent relevant, their beneficial owners, as the General Partner determines to be necessary to establish those Limited Partners whose U.S. federal income tax status does not or would not have a material adverse effect on the rates that can be charged to customers by any Group Member or (y) in the case of a Citizenship Eligibility Trigger, the General Partner may obtain such proof of the nationality, citizenship or other related status of the Limited Partners (or, if any Limited Partner is a nominee holding for the account of another Person, the nationality, citizenship or other related status of such Person) as the General Partner determines to be necessary to establish those Limited Partners whose nationality, citizenship or other related status does not or would not subject any Group Member to a significant risk of cancellation or forfeiture of any of its properties or interests therein.

(b)Without limitation of the foregoing, the General Partner may require all Limited Partners to certify as to their (and their beneficial owners') status as Eligible Holders upon demand and on a regular basis, as determined by the General Partner, and may require transferees of Limited Partner Interests to so certify prior to being admitted to the Partnership as a Limited Partner (any such required certificate, an “Eligibility Certificate”).

(c)If any Limited Partner fails to furnish to the General Partner an Eligibility Certificate or other requested information of its (and its beneficial owners') status as an Eligible Holder within thirty (30) days (or such other period as the General Partner may determine) of receipt of a request from the General Partner to furnish an Eligibility Certificate or other requested information, or if upon receipt of such Eligibility Certificate or other requested information the General Partner determines that a Limited Partner or a transferee of a Limited Partner is not an Eligible Holder (such a Partner, an “Ineligible Holder”), the Limited Partner Interests owned by such Limited Partner shall be subject to redemption in accordance with the provisions of Section 4.10 or the General Partner may refuse to effect the transfer of the Limited Partner Interests to such transferee. In addition, the General Partner shall be substituted for any Limited Partner that is an Ineligible Holder as the Limited Partner in respect of the Ineligible Holder's Limited Partner Interests.

(d)The General Partner shall, in exercising voting rights in respect of Limited Partner Interests held by it on behalf of Ineligible Holders, distribute the votes in the same ratios as the votes of Limited Partners (including the General Partner and its Affiliates) in respect of Limited

47

Partner Interests other than those of Ineligible Holders are cast, either for, against or abstaining as to the matter.

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

(f)At any time after an Ineligible Holder can and does certify that it no longer is an Ineligible Holder, it may, upon application to the General Partner, request that with respect to any Limited Partner Interests of such Ineligible Holder not redeemed pursuant to Section 4.10, such Ineligible Holder be admitted as a Limited Partner, and upon approval of the General Partner, such Ineligible Holder shall be admitted as Limited Partner and shall no longer constitute an Ineligible Holder, and the General Partner shall cease to be deemed to be the Limited Partner in respect of such Limited Partner Interests.

Section 4.10    Redemption of Partnership Interests of Ineligible Holders.

(a)If at any time a Limited Partner fails to furnish an Eligibility Certificate or any information requested within thirty (30) days (or such other period as the General Partner may determine) of receipt of a request from the General Partner to furnish an Eligibility Certificate, or if upon receipt of such Eligibility Certificate or such other information the General Partner determines, with the advice of counsel, that a Limited Partner is an Ineligible Holder, the Partnership may, unless the Limited Partner establishes to the satisfaction of the General Partner that such Limited Partner is not an Ineligible Holder or has transferred his Limited Partner Interests to a Person who is not an Ineligible Holder and who furnishes an Eligibility Certificate to the General Partner prior to the date fixed for redemption as provided below, redeem the Limited Partner Interest of such Limited Partner as follows:

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

(ii)The aggregate redemption price for Redeemable Interests shall be an amount equal to the Current Market Price (the date of determination of which shall be the date fixed for redemption) of Limited Partner Interests of the class to be so redeemed multiplied by the number of Limited Partner Interests of each such class included among

48

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

(iii)The Limited Partner or his duly authorized representative shall be entitled to receive the payment for the Redeemable Interests at the place of payment specified in the notice of redemption on the redemption date (or, if later in the case of Redeemable Interests evidenced by Certificates, upon surrender by or on behalf of the Limited Partner or transferee at the place specified in the notice of redemption, of the Certificates evidencing the Redeemable Interests, duly endorsed in blank or accompanied by an assignment duly executed in blank).

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

(b)The provisions of this Section 4.10 shall also be applicable to Limited Partner Interests held by a Limited Partner as nominee, agent or representative of a Person determined to be an Ineligible Holder.

(c)Nothing in this Section 4.10 shall prevent the recipient of a notice of redemption from transferring his Limited Partner Interest before the redemption date if such transfer is otherwise permitted under this Agreement and the transferor provides notice of such transfer to the General Partner. Upon receipt of notice of such a transfer, the General Partner shall withdraw the notice of redemption, provided that the transferee of such Limited Partner Interest certifies to the satisfaction of the General Partner that such transferee is not an Ineligible Holder. If the transferee fails to make such certification within 30 days after the request, and, in any event, before the redemption date, such redemption shall be effected from the transferee on the original redemption date.

Section 4.11    Right of First Offer.

(a)Subject to Section 4.8 and Section 4.11(d), except for a Permitted Transfer or a transfer to which Section 4.12 applies, if a Limited Partner (a “ROFO Seller”) wishes to solicit proposals from third parties to acquire all or any portion of the ROFO Seller's Common Units or Subordinated Units, the ROFO Seller shall first provide a written notice (the “ROFO Notice”) to each other Limited Partner (or, in the case of a transfer of Subordinated Units, only to the other Limited Partners holding Subordinated Units), with a copy to the Partnership, containing: (i) the number of Common Units or Subordinated Units proposed to be transferred (the “ROFO Units”) and (ii) a request for each other Limited Partner entitled to receive such notice (each, a “ROFO Non-Selling Limited Partner”) to specify the purchase price (the “ROFO Price”) and other terms and conditions on which such ROFO Non-Selling Limited Partner is willing to purchase the ROFO Units.

(b)If the ROFO Seller is a Person other than Bronco:

49

(i)Within thirty (30) days after receiving the ROFO Notice, one or more ROFO Non-Selling Limited Partners (each, a “ROFO Accepting Limited Partner” and, collectively, the “ROFO Accepting Limited Partners”) may elect in writing (the “ROFO Offer Notice”) to purchase all, but not less than all, of the ROFO Units. The ROFO Offer Notice shall specify the ROFO Price and other terms and conditions on which such ROFO Non-Selling Limited Partner is willing to purchase the ROFO Units. If any ROFO Accepting Limited Partner submits a ROFO Offer Notice within the time period specified herein, the ROFO Seller shall have thirty (30) days from the date it received the ROFO Offer Notice to elect in writing (the “ROFO Acceptance Notice”) to accept the ROFO Accepting Limited Partner's offer to purchase the ROFO Units.

(ii)If the ROFO Seller accepts a ROFO Accepting Limited Partner's offer, the ROFO Accepting Limited Partner must purchase the ROFO Units in the manner, and subject to the terms and conditions, described in Section 4.11(e). If the ROFO Seller does not accept any offer from a ROFO Accepting Limited Partner or fails to make such election within thirty (30) days after receiving the ROFO Offer Notice, or if there are no ROFO Accepting Limited Partners, then the ROFO Seller may, during the next one hundred twenty (120) days, transfer the ROFO Units to a third-party transferee (i) at a purchase price not less than 105% of the highest offered ROFO Price and upon terms no more favorable to the proposed transferee than those specified in the ROFO Notice and (ii) subject to the applicable terms and restrictions of this Agreement, including Section 4.8.

(iii)If more than one ROFO Accepting Limited Partner submits a ROFO Offer Notice and the ROFO Seller decides to accept any of such ROFO Offer Notices, then the ROFO Seller shall be obligated to accept such ROFO Offer Notice containing the highest offered ROFO Price. If the highest offered ROFO Price is submitted by more than one ROFO Accepting Limited Partner, each such ROFO Accepting Limited Partner shall be allocated a number of ROFO Units on a Pro Rata basis in accordance with the number of Common Units or Subordinated Units, as applicable, owned by such ROFO Accepting Limited Partner in relation to the total number of Common Units or Subordinated Units, as applicable, owned by all ROFO Accepting Limited Partners, or in such other proportion as such ROFO Accepting Limited Partners shall otherwise agree.

(c)If the ROFO Seller is Bronco:

(i)Within thirty (30) days after receiving the ROFO Notice, either OGEH or CERC may elect to submit a ROFO Offer Notice to purchase all, but not less than all, of the ROFO Units, which ROFO Offer Notice shall specify the ROFO Price and other terms and conditions on which OGEH or CERC (as applicable) would be willing to purchase the ROFO Units.

(ii)If both OGEH and CERC submit a ROFO Offer Notice within the time period specified in Section 4.11(c)(i) and the ROFO Seller decides to accept any of such ROFO Offer Notices, then the ROFO Seller shall be obligated to accept such ROFO Offer Notice containing the highest offered ROFO Price. If both OGEH and CERC submit a ROFO Offer Notice within the time period specified in Section 4.11(c)(i) at the

50

same ROFO Offer Price and the ROFO Seller elects to accept any of such ROFO Offer Notices, then the ROFO Seller shall be obligated to accept the ROFO Offer Notice submitted by OGEH.

(iii)If either OGEH or CERC submits a ROFO Offer Notice within the applicable time period specified in Section 4.11(c)(i), subject to Section 4.1(c)(ii), the ROFO Seller will have thirty (30) days from the date it received the ROFO Offer Notice to submit a ROFO Acceptance Notice.

(iv)If the ROFO Seller accepts an offer from OGEH or CERC, OGEH or CERC must purchase the ROFO Units in the manner, and subject to the terms and conditions, described in Section 4.11(e). If the ROFO Seller does not accept such offer or fails to make such election within thirty (30) days after receiving the ROFO Offer Notice, or neither OGEH or CERC submits a ROFO Offer Notice within the applicable time period specified in Section 4.11(c)(i), then the ROFO Seller may, during the next one hundred twenty (120) days, transfer the ROFO Units to a third-party transferee (i) at a purchase price not less than 105% of the highest offered ROFO Price and upon terms no more favorable to the proposed transferee than those specified in the ROFO Notice and (ii) subject to the applicable terms and restrictions of this Agreement, including Section 4.8.

(d)Except as set forth below, the obligations in this Section 4.11 shall apply to any proposed transfer of Common Units or Subordinated Units by a Limited Partner prior to the IPO Closing Date. The obligations in this Section 4.11 shall not apply to any such proposed transfer by Bronco after the earlier of the IPO Closing Date and the date that is 18 months following the Closing Date. On and after the IPO Closing Date, the obligations in this Section 4.11 shall apply only to any proposed transfer of Common Units or Subordinated Units, or series of such transfers to the same Person, by a Sponsor Party involving more than 5% of the aggregate of the Common Units and Subordinated Units held by such Sponsor Party. After the IPO Closing Date, the only Limited Partners entitled to receive a ROFO Notice and deliver a ROFO Offer Notice shall be the Sponsor Parties.

(e)Sales of the ROFO Units to the applicable ROFO Accepting Limited Partner pursuant to this Section 4.11 shall be made at the offices of the Partnership within sixty (60) days of the delivery of ROFO Acceptance Notice, or on such other date as the participating parties may agree in writing. Such sales shall be effected by the ROFO Seller's delivery of the ROFO Units, free and clear of all Encumbrances (other than restrictions imposed by the governing documents of the Partnership and securities laws), to the applicable ROFO Accepting Limited Partner, against payment to the ROFO Seller of the ROFO Price by the applicable ROFO Accepting Limited Partner and on the terms and conditions specified in the applicable ROFO Offer Notice.

Section 4.12    Right of First Refusal.

(a)Subject to Section 4.8 and Section 4.12(d), except for a Permitted Transfer or a transfer to which Section 4.11 applies, if a Limited Partner (a “ROFR Seller”) receives an unsolicited bona fide offer from a third party for a transfer of all or any portion of the ROFR

51

Seller's Common Units or Subordinated Units, and the ROFR Seller wishes to accept such offer, the ROFR Seller shall first provide a written notice (the “ROFRSeller's Notice”) to each other Limited Partner (or, in the case of a transfer of Subordinated Units, only to the other Limited Partners holding Subordinated Units), with a copy to the Partnership, containing: (i) the number of Common Units or Subordinated Units proposed to be transferred (the “ROFR Units”) and the per Unit purchase price offered therefor, which may only be in cash (the “ROFR Sale Price”), and (ii) the material terms and conditions of such proposed transfer. Delivery of the ROFR Seller's Notice to the Limited Partners entitled to receive such notice (each, a “ROFR Non-Transferring Limited Partner”) shall constitute an offer (a “ROFR Offer”) by the ROFR Seller to sell the ROFR Units at the ROFR Sale Price to each other ROFR Non-Transferring Limited Partner, which shall remain outstanding for a period of thirty (30) days after the delivery of the ROFR Seller's Notice (subject to extension as provided below, the “ROFR Period”).

(b)If the ROFR Seller is a Person other than Bronco:

(i)During the ROFR Period, each ROFR Non-Transferring Limited Partner shall have the right to accept the ROFR Offer in full but not in part, by delivering a written notice to the ROFR Seller (a “ROFRAcceptance Notice”), with a copy to each other ROFR Non-Transferring Limited Partner and the Partnership of its acceptance of the ROFR Offer with respect to all of the ROFR Units at the ROFR Sale Price and on the same terms specified in the ROFR Seller's Notice.

(ii)If more than one ROFR Acceptance Notice is timely delivered to the ROFR Seller, each ROFR Non-Transferring Limited Partner that submitted a ROFR Acceptance Notice shall be entitled to purchase a portion of the ROFR Units determined on a pro rata basis in accordance with the number of Common Units or Subordinated Units, as applicable, owned by each such participating ROFR Non-Transferring Limited Partner in relation to the total number of Common Units or Subordinated Units, as applicable, owned by all such participating ROFR Non-Transferring Limited Partners, or in such other proportion as such ROFR Non-Transferring Limited Partners may agree.

(iii)A failure by a ROFR Non-Transferring Limited Partner to validly deliver a ROFR Acceptance Notice during the ROFR Period shall be deemed a rejection of the ROFR Offer and a waiver of such ROFR Non-Transferring Limited Partner's right to purchase any portion of the ROFR Units.

(iv)If no ROFR Non-Transferring Limited Partner timely delivers a ROFR Acceptance Notice, then the ROFR Seller shall be free, for a period of one hundred twenty (120) days from the date of the expiration of the ROFR Period, to sell such ROFR Units to a third party (the “Proposed Transferee”) (x) at a price per Unit equal to or greater than the ROFR Price and upon terms no more favorable to the Proposed Transferee than those specified in the ROFR Seller's Notice and (y) subject to the applicable terms and restrictions of this Agreement, including Section 4.8.

(c)If the ROFR Seller is Bronco:

52

(i)During the ROFR Period, OGEH and CERC shall each have the right to accept the ROFR Offer in full but not in part, in each case by delivering a ROFR Acceptance Notice, with a copy to each other ROFR Non-Transferring Limited Partner and the Partnership of its acceptance of the ROFR Offer with respect to all of the ROFR Units at the ROFR Sale Price and on the same terms specified in the ROFR Seller's Notice.

(ii)If both OGEH and CERC timely submit a ROFR Acceptance Notice, then OGEH shall be entitled to purchase all of the ROFR Units, unless OGEH and CERC agree otherwise.

(iii)A failure by OGEH or CERC to validly deliver a ROFR Acceptance Notice during the applicable ROFR Period shall be deemed a rejection of the ROFR Offer and a waiver of such party's right to purchase any portion of the ROFR Units.

(iv)If neither OGEH or CERC timely delivers a ROFR Acceptance Notice, then the ROFR Seller shall be free, for a period of one hundred twenty (120) days from the date of the expiration of the ROFR Period, to sell such ROFR Units to a Proposed Transferee (x) at a price per Unit equal to or greater than the ROFR Price and upon terms no more favorable to the Proposed Transferee than those specified in the ROFR Seller's Notice and (y) subject to the applicable terms and restrictions of this Agreement, including Section 4.8.

(d)Except as set forth below, the obligations in this Section 4.12 shall apply to any proposed transfer of Common Units or Subordinated Units by a Limited Partner prior to the IPO Closing Date. The obligations in this Section 4.12 shall not apply to any such proposed transfer by Bronco after the earlier of the IPO Closing Date and the date that is 18 months following the Closing Date. On and after the IPO Closing Date, the obligations in this Section 4.12 shall apply only to any proposed transfer of Common Units or Subordinated Units, or series of such transfers to the same Person, by a Sponsor Party involving more than 5% of the aggregate of the Common Units or Subordinated Units held by such Sponsor Party. After the IPO Closing Date, the only Limited Partners entitled to receive a ROFR Seller's Notice and deliver a ROFR Acceptance Notice shall be the Sponsor Parties.

(e)Sales of the ROFR Units to be sold to the participating ROFR Non-Transferring Limited Partners pursuant to this Section 4.12 shall be made at the offices of the Partnership within sixty (60) days of the delivery of ROFR Seller's Notice, or on such other date as the participating parties may agree in writing. Such sales shall be effected by the ROFR Seller's delivery of the ROFR Units, free and clear of all Encumbrances (other than restrictions imposed by the governing documents of the Partnership and securities laws), to the participating ROFR Non-Transferring Limited Partners, against payment to the ROFR Seller of the purchase consideration therefor by the participating ROFR Non-Transferring Limited Partners and on the terms and conditions specified in the ROFR Seller's Notice.

Except to the extent expressly provided in this Agreement, no Partner shall have priority over any other Partner either as to the return of Capital Contributions

54

or as to profits, losses or distributions. Any such return shall be a compromise to which all Partners agree within the meaning of Section 17-502(b) of the Delaware Act.

Section 5.5    Capital Accounts.

(a)The Partnership shall maintain for each Partner (or a beneficial owner of Partnership Interests held by a nominee, agent or representative in any case in which the nominee, agent or representative has furnished the identity of such owner to the Partnership in accordance with Section 6031(c) of the Code or any other method acceptable to the General Partner) owning a Partnership Interest a separate Capital Account with respect to such Partnership Interest in accordance with the rules of Treasury Regulation Section 1.704-1(b)(2)(iv). The initial Capital Account balance attributable to the Common Units issued to the Organizational Limited Partner, OGEH, and Bronco pursuant to Sections 5.1 and 5.2(a) shall equal the product of the number of Common Units issued to the Organizational Limited Partner, OGEH, and Bronco, respectively, and the Initial Unit Price for each such Common Unit (and the initial Capital Account balance attributable to each such Common Unit shall equal its Initial Unit Price). The initial Capital Account attributable to the Incentive Distribution Rights shall be zero.. Such Capital Account shall be increased by (i) the amount of all Capital Contributions made to the Partnership with respect to such Partnership Interest and (ii) all items of Partnership income and gain (including income and gain exempt from tax) computed in accordance with Section 5.5(b) and allocated with respect to such Partnership Interest pursuant to Section 6.1, and decreased by (x) the amount of cash or Net Agreed Value of all actual and deemed distributions of cash or property made with respect to such Partnership Interest and (y) all items of Partnership deduction and loss computed in accordance with Section 5.5(b) and allocated with respect to such Partnership Interest pursuant to Section 6.1.

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

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

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

55

(iii)Except as otherwise provided in Treasury Regulation Section 1.704-1(b)(2)(iv)(m), the computation of all items of income, gain, loss and deduction shall be made without regard to any election under Section 754 of the Code that may be made by the Partnership and, as to those items described in Section 705(a)(1)(B) or 705(a)(2)(B) of the Code, without regard to the fact that such items are not includable in gross income or are neither currently deductible nor capitalized for federal income tax purposes. To the extent an adjustment to the adjusted tax basis of any Partnership asset pursuant to Section 734(b) or 743(b) of the Code is required, pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts, the amount of such adjustment in the Capital Accounts shall be treated as an item of gain or loss.

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

(v)In accordance with the requirements of Section 704(b) of the Code, any deductions for depreciation, cost recovery or amortization attributable to any Contributed Property shall be determined as if the adjusted basis of such property on the date it was acquired by the Partnership were equal to the Agreed Value of such property. Upon an adjustment pursuant to Section 5.5(d) to the Carrying Value of any Partnership property subject to depreciation, cost recovery or amortization, any further deductions for such depreciation, cost recovery or amortization attributable to such property shall be determined under the rules prescribed by Treasury Regulation Section 1.704-3(d)(2) as if the adjusted basis of such property were equal to the Carrying Value of such property immediately following such adjustment.

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

(c)

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

(ii)Subject to Section 6.8(c), immediately prior to the transfer of a Subordinated Unit or of a Subordinated Unit that has converted into a Common Unit pursuant to Section 5.8 by a holder thereof (other than a transfer to an Affiliate unless the General Partner elects to have this subparagraph 5.5(c)(ii) apply), the Capital Account maintained for such Person with respect to its Subordinated Units or converted Subordinated Units will (A)first, be allocated to the Subordinated Units or converted Subordinated Units to be transferred in an amount equal to the product of (x) the number

56

of such Subordinated Units or converted Subordinated Units to be transferred and (y) the Per Unit Capital Amount for a Common Unit, and (B)second, any remaining balance in such Capital Account will be retained by the transferor, regardless of whether it has retained any Subordinated Units or converted Subordinated Units. Following any such allocation, the transferor's Capital Account, if any, maintained with respect to the retained Subordinated Units or retained converted Subordinated Units, if any, will have a balance equal to the amount allocated under clause (B) hereinabove, and the transferee's Capital Account established with respect to the transferred Subordinated Units or transferred converted Subordinated Units will have a balance equal to the amount allocated under clause (A) hereinabove.

(iii)Subject to Section 6.8(b), immediately prior to the transfer of an IDR Reset Common Unit by a holder thereof (other than a transfer to an Affiliate unless the General Partner elects to have this subparagraph (iii) apply), the Capital Account maintained for such Person with respect to its IDR Reset Common Units will (A) first, be allocated to the IDR Reset Common Units to be transferred in an amount equal to the product of (x) the number of such IDR Reset Common Units to be transferred and (y) the Per Unit Capital Amount for a Common Unit, and (B) second, any remaining balance in such Capital Account will be retained by the transferor, regardless of whether it has retained any IDR Reset Common Units. Following any such allocation, the transferor's Capital Account, if any, maintained with respect to the retained IDR Reset Common Units, if any, will have a balance equal to the amount allocated under clause (B) hereinabove, and the transferee's Capital Account established with respect to the transferred IDR Reset Common Units will have a balance equal to the amount allocated under clause (A) above.

(d)

(i)Consistent with Treasury Regulation Section 1.704-1(b)(2)(iv)(f), on an issuance of additional Partnership Interests for cash or Contributed Property, the issuance of Partnership Interests as consideration for the provision of services, or the conversion of the General Partner's Combined Interest to Common Units pursuant to Section 11.3(b), the Capital Account of each Partner and the Carrying Value of each Partnership property immediately prior to such issuance shall be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Partnership property, and any such Unrealized Gain or Unrealized Loss shall be treated, for purposes of maintaining Capital Accounts, as if it had been recognized on an actual sale of each such property for an amount equal to its fair market value immediately prior to such issuance and had been allocated among the Partners at such time pursuant to Section 6.1(c) and Section 6.1(d) in the same manner as any item of gain or loss actually recognized following an event giving rise to the dissolution of the Partnership would have been allocated; provided, however, that in the event of an issuance of Partnership Interests for a de minimis amount of cash or Contributed Property, or in the event of an issuance of a de minimis amount of Partnership Interests as consideration for the provision of services, the General Partner may determine that such adjustments are unnecessary for the proper administration of the Partnership. In determining such Unrealized Gain or Unrealized Loss, the aggregate fair market value of all Partnership property (including cash or cash equivalents) immediately

57

prior to the issuance of additional Partnership Interests shall be determined by the General Partner using such method of valuation as it may adopt. In making its determination of the fair market values of individual properties, the General Partner may determine that it is appropriate to first determine an aggregate value for the Partnership, derived from the current trading price of the Common Units, and taking fully into account the fair market value of the Partnership Interests of all Partners at such time, and then allocate such aggregate value among the individual properties of the Partnership (in such manner as it determines appropriate).

(ii)In accordance with Treasury Regulation Section 1.704-1(b)(2)(iv)(f), immediately prior to any actual or deemed distribution to a Partner of any Partnership property (other than a distribution of cash that is not in redemption or retirement of a Partnership Interest), the Capital Accounts of all Partners and the Carrying Value of all Partnership property shall be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Partnership property, and any such Unrealized Gain or Unrealized Loss shall be treated, for purposes of maintaining Capital Accounts, as if it had been recognized on an actual sale of each such property immediately prior to such distribution for an amount equal to its fair market value, and had been allocated among the Partners, at such time, pursuant to Section 6.1(c) and Section 6.1(d) in the same manner as any item of gain or loss actually recognized following an event giving rise to the dissolution of the Partnership would have been allocated. In determining such Unrealized Gain or Unrealized Loss the aggregate fair market value of all Partnership property (including cash or cash equivalents) immediately prior to a distribution shall (A) in the case of an actual distribution that is not made pursuant to Section 12.4 or in the case of a deemed distribution, be determined in the same manner as that provided in Section 5.5(d)(i) or (B) in the case of a liquidating distribution pursuant to Section 12.4, be determined by the Liquidator using such method of valuation as it may adopt.

Section 5.6    Issuances of Additional Partnership Interests; Additional Capital Contributions Prior to the IPO Closing Date; Call and Put Rights.

(a)The Partnership may issue additional Partnership Interests (other than General Partner Interests) and Derivative Partnership Interests for any Partnership purpose at any time and from time to time to such Persons for such consideration and on such terms and conditions as the General Partner shall determine, all without the approval of any Limited Partners (subject to Section 3.4(a)). Notwithstanding anything to the contrary in this Agreement, prior to the Bronco Fall-Away Date, the Partnership shall not issue any Units with designations, preferences, rights, powers or duties that are senior to Common Units held by Bronco without the prior written consent of Bronco.

(b)Each additional Partnership Interest authorized to be issued by the Partnership pursuant to Section 5.6(a) may be issued in one or more classes, or one or more series of any such classes, with such designations, preferences, rights, powers and duties (which, except as otherwise provided in Section 5.6(a), may be senior to existing classes and series of Partnership Interests), as shall be fixed by the General Partner, including (i) the right to share in Partnership profits and losses or items thereof; (ii) the right to share in Partnership distributions; (iii) the

58

rights upon dissolution and liquidation of the Partnership; (iv) whether, and the terms and conditions upon which, the Partnership may or shall be required to redeem the Partnership Interest; (v) whether such Partnership Interest is issued with the privilege of conversion or exchange and, if so, the terms and conditions of such conversion or exchange; (vi) the terms and conditions upon which each Partnership Interest will be issued, evidenced by Certificates and assigned or transferred; (vii) the method for determining the Percentage Interest as to such Partnership Interest; and (viii) the right, if any, of each such Partnership Interest to vote on Partnership matters, including matters relating to the relative rights, preferences and privileges of such Partnership Interest.

(c)The General Partner shall take all actions that it determines to be necessary or appropriate in connection with (i) each issuance of Partnership Interests and Derivative Partnership Interests pursuant to this Section 5.6, (ii) the conversion of the Combined Interest into Units pursuant to the terms of this Agreement, (iii) the issuance of Common Units pursuant to Section 5.12, (iv) reflecting admission of such additional Limited Partners in the Register as the Record Holders of such Limited Partner Interests and (v) all additional issuances of Partnership Interests. The General Partner shall determine the relative rights, powers and duties of the holders of the Units or other Partnership Interests being so issued. The General Partner shall do all things necessary to comply with the Delaware Act and is authorized and directed to do all things that it determines to be necessary or appropriate in connection with any future issuance of Partnership Interests or in connection with the conversion of the Combined Interest into Units pursuant to the terms of this Agreement, including compliance with any statute, rule, regulation or guideline of any federal, state or other governmental agency or any National Securities Exchange on which the Units or other Partnership Interests are listed or admitted to trading.

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

(e)Additional Capital Contributions Prior to the IPO Closing Date.

(i)Prior to the IPO Closing Date, each Limited Partner shall have the right, but not the obligation, to fund its Pro Rata portion of any additional Capital Contributions approved by the Board of Directors.

(ii)If a Limited Partner elects not to fund any amount of its Pro Rata portion of an additional Capital Contribution, then the other Limited Partners shall have the right, but not the obligation, to fund their Pro Rata portion of the remaining balance of such unfunded Capital Contribution. In such event, the General Partner shall give the other Limited Partners written notice thereof.

(iii)Each time a request for additional Capital Contributions is to be made, the Partnership shall give each Limited Partner a written notice specifying (A) the aggregate amount of the Capital Contribution requested and such Limited Partner's share thereof, and (B) wire instructions for the account into which such Capital Contribution shall be made. Except as otherwise approved by the Board of Directors, the Limited Partners shall make any Capital Contributions requested hereunder (X) within fifteen (15) days of the date that the notice in the preceding sentence is given by the Partnership, or

59

(Y) within ten (10) days of the date such Limited Partner is given notice by the Partnership that it is entitled to fund a balance of a Capital Contribution pursuant to Section 5.6(e)(ii), in each case subject to any extension necessary to pursue any required regulatory approvals or clearances.

(iv)In exchange for payment of any additional Capital Contributions as provided in this Section 5.6(e), the Partnership shall issue to each Limited Partner that elects to fund such additional Capital Contribution a number of additional Common Units equal to (i) the dollar amount of such Capital Contribution funded by the Limited Partner divided by (ii) 80% of then-applicable Unit Price.

(A)As used herein, “Unit Price” means the Partnership Equity Value at such time, divided by the sum of the number of Common Units Outstanding on such date. The Unit Price shall be determined by the General Partner.

(B)As used herein, “Partnership Equity Value” shall be derived from a 5.8% yield (coinciding with a 5.97% Alerian MLP Index Yield (AMZ Yield) as of March 2013) as adjusted on the date of determination to reflect changes in the Alerian MLP Index Yield and the aggregate amount of Adjusted Available Cash for the four most recently completed Quarters. For purposes of this Section 5.6(e)(iv), the aggregate amount of Adjusted Available Cash for the four most recent Quarters occurring immediately prior to the first quarter after the Closing Date shall be the relevant historical or projected amounts for such periods provided in Exhibit D. An example of the calculation of the Unit Price is included as Exhibit D.

(f)Issuance of Units with Respect to Call and Put Rights. If a Call Right or a Put Right is exercised, in exchange for the Partnership purchasing an additional interest in SESH as provided in Annex B to the Master Formation Agreement, the Partnership shall issue to SEPH a number of additional Common Units as determined pursuant to Annex B to the Master Formation Agreement.

Section 5.7Conversion of Common Units Into Subordinated Units. In connection with the Initial Public Offering, the General Partner may, in its sole and absolute discretion and upon written notice to the Limited Partners, convert such portion of the Common Units held by each of CERC and OGEH (or their respective successors) as is necessary to cause up to 50% of the Outstanding Units on the IPO Closing Date to be Subordinated Units into Subordinated Units on a one-for-one basis without the necessity of any vote or approval of any other Partner; provided, however, that each of CERC and OGEH (or their respective successors) must have the same percentage of such Person's Common Units converted into Subordinated Units. From and after the date of any such conversion, the provisions of this Agreement relating to Subordinated Units, including the provisions of ýSection 5.8, shall apply.

Section 5.8    Conversion of Subordinated Units.

(a)All of the Subordinated Units shall convert into Common Units on a one-for-one basis on the expiration of the Subordination Period.

60

(b)In the event that Subordinated Units shall convert into Common Units pursuant to Section 5.8(a) at a time when there shall be more than one holder of Subordinated Units, then, unless all of the holders of the Subordinated Units shall agree to a different allocation, the Subordinated Units that are to be converted into Common Units shall be allocated among the holders of the Subordinated Units pro rata based on the number of Subordinated Units held by each such holder.

(c)Upon the conversion of Subordinated Units in accordance with this Section 5.8, each converting holder shall be deemed to be the Record Holder of the number of Common Units issuable upon conversion, notwithstanding that the Certificates representing such Common Units shall not then actually be delivered to such Person. Upon notice from the Partnership, each holder of Subordinated Units so converted shall promptly surrender to the Partnership Certificates representing the Subordinated Units so converted, in proper transfer form. If the date for the conversion of Subordinated Units into Common Units shall not be a Business Day, then such conversion shall occur on the next Business Day. Each Subordinated Unit shall be canceled by the General Partner upon its conversion.

(d)The issuance or delivery of certificates for Common Units upon the conversion of Subordinated Units shall be made without charge to the converting holder of Subordinated Units for such certificates or for any tax in respect of the issuance or delivery of such certificates or the securities represented thereby, and such certificates shall be issued or delivered in the respective names of, or in such names as may be directed by, the holders of the Subordinated Units converted; provided, however, that the Partnership shall not be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of any such certificate in a name other than that of the holder of the Subordinated Units converted, and the Partnership shall not be required to issue or deliver such certificate unless or until the Person or Persons requesting the issuance or delivery thereof shall have paid to the Partnership the amount of such tax or shall have established to the reasonable satisfaction of the Partnership that such tax has been paid.

(e)A Subordinated Unit that has converted into a Common Unit shall be subject to the provisions of Section 6.8.

Section 5.9    Limited Preemptive Right. Except as provided in this Section 5.9 and in Section 5.2 and Section 5.12 or as otherwise provided in a separate agreement by the Partnership, no Person shall have any preemptive, preferential or other similar right with respect to the issuance of any Partnership Interest, whether unissued, held in the treasury or hereafter created. After the IPO Closing Date, for so long as a Person remains an Affiliate of the General Partner, each Affiliate of the General Partner shall have the right, which it may from time to time assign in whole or in part to any of its Affiliates, to purchase Partnership Interests from the Partnership whenever, and on the same terms that, the Partnership issues Partnership Interests to Persons other than the General Partner and its Affiliates, up to the extent necessary to maintain the Percentage Interests of such Person equal to that which existed immediately prior to the issuance of such Partnership Interests.

Section 5.10    Splits and Combinations.

61

(a)Subject to Section 5.10(d), Section 6.7 and Section 6.10 (dealing with adjustments of distribution levels), the Partnership may make a Pro Rata distribution of Partnership Interests to all Record Holders or may effect a subdivision or combination of Partnership Interests so long as, after any such event, each Partner shall have the same Percentage Interest in the Partnership as before such event, and any amounts calculated on a per Unit basis (including any Common Unit Arrearage, Cumulative Common Unit Arrearage or Minimum Bronco Pre-IPO MQD Amount) or stated as a number of Units are proportionately adjusted.

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

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

(d)The Partnership shall not issue fractional Units upon any distribution, subdivision or combination of Units. If a distribution, subdivision or combination of Units would result in the issuance of fractional Units but for the provisions of Section 5.6(d) and this Section 5.10(d), each fractional Unit shall be rounded to the nearest whole Unit (with fractional Units equal to or greater than a 0.5 Unit being rounded to the next higher Unit).

Section 5.11    Fully Paid and Non-Assessable Nature of Limited Partner Interests. All Limited Partner Interests issued pursuant to, and in accordance with the requirements of, this Article V shall be fully paid and non-assessable Limited Partner Interests in the Partnership, except as such non-assessability may be affected by Sections 17-303, 17-607 or 17-804 of the Delaware Act.

Section 5.12    Issuance of Common Units in Connection with Reset of Incentive Distribution Rights.

(a)Subject to the provisions of this Section 5.12, the holder of the Incentive Distribution Rights (or, if there is more than one holder of the Incentive Distribution Rights, the holders of a majority in interest of the Incentive Distribution Rights) shall have the right, at any time when there are no Subordinated Units outstanding and the Partnership has made a

62

distribution pursuant to Section 6.5(b)(v) for each of the four most recently completed Quarters and the amount of each such distribution did not exceed Adjusted Operating Surplus for such Quarter, to make an election (the “IDR Reset Election”) to cause the Minimum Quarterly Distribution and the Target Distributions to be reset in accordance with the provisions of Section 5.12(e) and, in connection therewith, the holder or holders of the Incentive Distribution Rights will become entitled to receive their respective proportionate share of a number of Common Units (the “IDR Reset Common Units”) derived by dividing (i) the average amount of cash distributions made by the Partnership for the two full Quarters immediately preceding the giving of the Reset Notice (as defined in Section 5.12(b)) in respect of the Incentive Distribution Rights by (ii) the average of the cash distributions made by the Partnership in respect of each Common Unit for the two full Quarters immediately preceding the giving of the Reset Notice (the number of Common Units determined by such quotient is referred to herein as the “Aggregate Quantity of IDR Reset Common Units”). If at the time of any IDR Reset Election the General Partner and its Affiliates are not the holders of a majority interest of the Incentive Distribution Rights, then the IDR Reset Election shall be subject to the prior written concurrence of the General Partner that the conditions described in the immediately preceding sentence have been satisfied. The making of the IDR Reset Election in the manner specified in this Section 5.12 shall cause the Minimum Quarterly Distribution and the Target Distributions to be reset in accordance with the provisions of Section 5.12(e) and, in connection therewith, the holder or holders of the Incentive Distribution Rights will become entitled to receive IDR Reset Common Units on the basis specified above, without any further approval required by the Unitholders other than as set forth in this Section 5.12(a), at the time specified in Section 5.12(c) unless the IDR Reset Election is rescinded pursuant to Section 5.12(d).

(b)To exercise the right specified in Section 5.12(a), the holder of the Incentive Distribution Rights (or, if there is more than one holder of the Incentive Distribution Rights, the holders of a majority in interest of the Incentive Distribution Rights) shall deliver a written notice (the “Reset Notice”) to the Partnership. Within 10 Business Days after the receipt by the Partnership of such Reset Notice, the Partnership shall deliver a written notice to the holder or holders of the Incentive Distribution Rights of the Partnership's determination of the Aggregate Quantity of IDR Reset Common Units that each holder of Incentive Distribution Rights will be entitled to receive.

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

(d)If the principal National Securities Exchange upon which the Common Units are then traded has not approved the listing or admission for trading of the IDR Reset Common Units to be issued pursuant to this Section 5.12 on or before the 30th calendar day following the Partnership's receipt of the Reset Notice and such approval is required by the rules and regulations of such National Securities Exchange, then the holder of the Incentive Distribution

63

Rights (or, if there is more than one holder of the Incentive Distribution Rights, the holders of a majority in interest of the Incentive Distribution Rights) shall have the right to either rescind the IDR Reset Election or elect to receive other Partnership Interests having such terms as the General Partner may approve, with the approval of the Conflicts Committee, that will provide (i) the same economic value, in the aggregate, as the Aggregate Quantity of IDR Reset Common Units would have had at the time of the Partnership's receipt of the Reset Notice, as determined by the General Partner, and (ii) for the subsequent conversion of such Partnership Interests into Common Units within not more than 12 months following the Partnership's receipt of the Reset Notice upon the satisfaction of one or more conditions that are reasonably acceptable to the holder of the Incentive Distribution Rights (or, if there is more than one holder of the Incentive Distribution Rights, the holders of a majority in interest of the Incentive Distribution Rights).

(e)The Minimum Quarterly Distribution and the Target Distributions, shall be adjusted at the time of the issuance of IDR Reset Common Units or other Partnership Interests pursuant to this Section 5.12 such that (i) the Minimum Quarterly Distribution shall be reset to equal the average cash distribution amount per Common Unit for the two Quarters immediately prior to the Partnership's receipt of the Reset Notice (the “Reset MQD”), (ii) the First Target Distribution shall be reset to equal 115% of the Reset MQD, (iii) the Second Target Distribution shall be reset to equal 125% of the Reset MQD and (iv) the Third Target Distribution shall be reset to equal 150% of the Reset MQD.

(f)Upon the issuance of IDR Reset Common Units pursuant to Section 5.12(a), the Capital Account maintained with respect to the Incentive Distribution Rights will (i) first, be allocated to IDR Reset Common Units in an amount equal to the product of (A) the Aggregate Quantity of IDR Reset Common Units and (B) the Per Unit Capital Amount for an IPO Common Unit, and (ii) second, as to any remaining balance in such Capital Account, will be retained by the holder of the Incentive Distribution Rights. If there is not sufficient capital associated with the Incentive Distribution Rights to allocate the full Per Unit Capital Amount for an IPO Common Unit to the IDR Reset Common Units in accordance with clause (i) of this Section 5.12(f), the IDR Reset Common Units shall be subject to Sections 6.1(d)(x)(B) and (C).

ARTICLE VI

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

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

(ii)Chargeback of Partner Nonrecourse Debt Minimum Gain. Notwithstanding the other provisions of this Section 6.1 (other than Section 6.1(d)(i)), except as provided in Treasury Regulation Section 1.704-2(i)(4), if there is a net decrease in Partner Nonrecourse Debt Minimum Gain during any Partnership taxable period, any Partner with a share of Partner Nonrecourse Debt Minimum Gain at the beginning of such taxable period shall be allocated items of Partnership income and gain for such period (and, if necessary, subsequent periods) in the manner and amounts provided in Treasury Regulation Sections 1.704-2(i)(4) and 1.704-2(j)(2)(ii), or any successor provisions.

(A)If the amount of cash or the Net Agreed Value of any property distributed (except cash or property distributed pursuant to Section 12.4) with respect to a Unit exceeds the amount of cash or the Net Agreed Value of property distributed with respect to another Unit (the amount of the excess, an “Excess Distribution” and the Unit with respect to which the greater distribution is paid, an “Excess Distribution Unit”), then there shall be allocated gross income and gain to each Unitholder receiving an Excess Distribution with respect to the Excess Distribution Unit until the aggregate amount of such items allocated with respect to such Excess Distribution Unit pursuant to this Section 6.1(d)(iii)(A) for the current taxable period and all previous taxable periods is equal to the amount of the Excess Distribution.

(B)After the application of Section 6.1(d)(iii)(A), all or any portion of the remaining items of Partnership gross income or gain for the taxable period, if any, shall be allocated to the holders of Incentive Distribution Rights, Pro Rata, until the aggregate amount of such items allocated to the holders of Incentive Distribution Rights pursuant to this Section 6.1(d)(iii)(B) for the current taxable period and all previous taxable periods is equal to the cumulative amount of all Incentive Distributions made to the holders of Incentive Distribution Rights from the Closing Date to a date 45 days after the end of the current taxable period.

(iv)Qualified Income Offset. In the event any Partner unexpectedly receives any adjustments, allocations or distributions described in Treasury Regulation Sections 1.704-1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5), or 1.704-1(b)(2)(ii)(d)(6), items of Partnership gross income and gain shall be specially allocated to such Partner in an amount and manner sufficient to eliminate, to the extent required by the Treasury Regulations promulgated under Section 704(b) of the Code, the deficit balance, if any, in its Adjusted Capital Account created by such adjustments, allocations or distributions as quickly as possible; provided, that an allocation pursuant to this Section 6.1(d)(iv) shall be made only if and to the extent that such Partner would have a deficit balance in its Adjusted Capital Account as adjusted after all other allocations provided for in this Section 6.1 have been tentatively made as if this Section 6.1(d)(iv) were not in this Agreement.

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

69

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

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

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

(ix)Code Section 754 Adjustments. To the extent an adjustment to the adjusted tax basis of any Partnership asset pursuant to Section 734(b) or 743(b) of the Code is required, pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts, the amount of such adjustment to the Capital Accounts shall be treated as an item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment decreases such basis), and such item of gain or loss shall be specially allocated to the Partners in a manner consistent with the manner in which their Capital Accounts are required to be adjusted pursuant to such Section of the Treasury Regulations.

(x)Economic Uniformity; Changes in Law.

(A)At the election of the General Partner with respect to any taxable period ending upon, or after, the termination of the Subordination Period, all or a portion of the remaining items of Partnership gross income or gain for such taxable period, after taking into account allocations pursuant to Section 6.1(d)(iii), shall be allocated 100% to each Partner holding Subordinated Units that are Outstanding as of the termination of the Subordination Period (“Final Subordinated Units”) in the proportion of the number of Final Subordinated Units held by such Partner to the total number of Final Subordinated Units then Outstanding, until each such Partner has been allocated an amount of gross income or gain that increases the Capital Account maintained with respect to such Final Subordinated Units to an amount that after taking into account the other allocations of income, gain, loss and deduction to be made with respect to such taxable period will equal the product of (A) the number of Final Subordinated

70

Units held by such Partner and (B) the Per Unit Capital Amount for a Common Unit. The purpose of this allocation is to establish uniformity between the Capital Accounts underlying Final Subordinated Units and the Capital Accounts underlying Common Units held by Persons other than the General Partner and its Affiliates immediately prior to the conversion of such Final Subordinated Units into Common Units. This allocation method for establishing such economic uniformity will be available to the General Partner only if the method for allocating the Capital Account maintained with respect to the Subordinated Units between the transferred and retained Subordinated Units pursuant to Section 5.5(c)(ii) does not otherwise provide such economic uniformity to the Final Subordinated Units.

(B)With respect to an event triggering an adjustment to the Carrying Value of Partnership property pursuant to Section 5.5(d) during any taxable period of the Partnership ending upon, or after, the issuance of IDR Reset Common Units pursuant to Section 5.12, after the application of Section 6.1(d)(x)(A), any Unrealized Gains and Unrealized Losses shall be allocated among the Partners in a manner that to the nearest extent possible results in the Capital Accounts maintained with respect to such IDR Reset Common Units issued pursuant to Section 5.12 equaling the product of (A) the Aggregate Quantity of IDR Reset Common Units and (B) the Per Unit Capital Amount for an IPO Common Unit.

(C)With respect to any taxable period during which an IDR Reset Unit is transferred to any Person who is not an Affiliate of the transferor, all or a portion of the remaining items of Partnership gross income or gain for such taxable period shall be allocated 100% to the transferor Partner of such transferred IDR Reset Common Unit until such transferor Partner has been allocated an amount of gross income or gain that increases the Capital Account maintained with respect to such transferred IDR Reset Unit to an amount equal to the Per Unit Capital Amount for an IPO Common Unit.

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

71

Outstanding or the Partnership, and if such allocations are consistent with the principles of Section 704 of the Code.

(xi)Curative Allocation.

(A)Notwithstanding any other provision of this Section 6.1, other than the Required Allocations, the Required Allocations shall be taken into account in making the Agreed Allocations so that, to the extent possible, the net amount of items of gross income, gain, loss and deduction allocated to each Partner pursuant to the Required Allocations and the Agreed Allocations, together, shall be equal to the net amount of such items that would have been allocated to each such Partner under the Agreed Allocations had the Required Allocations and the related Curative Allocation not otherwise been provided in this Section 6.1. Notwithstanding the preceding sentence, Required Allocations relating to (1) Nonrecourse Deductions shall not be taken into account except to the extent that there has been a decrease in Partnership Minimum Gain and (2) Partner Nonrecourse Deductions shall not be taken into account except to the extent that there has been a decrease in Partner Nonrecourse Debt Minimum Gain. In exercising its discretion under this Section 6.1(d)(xi)(A), the General Partner may take into account future Required Allocations that, although not yet made, are likely to offset other Required Allocations previously made. Allocations pursuant to this Section 6.1(d)(xi)(A) shall only be made with respect to Required Allocations to the extent the General Partner determines that such allocations will otherwise be inconsistent with the economic agreement among the Partners. Further, allocations pursuant to this Section 6.1(d)(xi)(A) shall be deferred with respect to allocations pursuant to clauses (1) and (2) hereof to the extent the General Partner determines that such allocations are likely to be offset by subsequent Required Allocations.

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

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

(A)Except as provided in Section 6.1(d)(xii)(B), in the case of any allocation of Additional Book Basis Derivative Items (other than an allocation of Unrealized Gain or Unrealized Loss under Section 5.5(d) hereof), the General Partner shall allocate such Additional Book Basis Derivative Items to (1) the holders of Incentive Distribution Rights and the General Partner to the same extent that the Unrealized Gain or Unrealized Loss giving rise to such Additional Book Basis Derivative Items was allocated to them pursuant to Section 5.5(d) and (2) all Unitholders, Pro Rata, to the extent that the Unrealized Gain or Unrealized

72

Loss giving rise to such Additional Book Basis Derivative Items was allocated to any Unitholders pursuant to Section 5.5(d).

(B)In the case of any allocation of Additional Book Basis Derivative Items (other than an allocation of Unrealized Gain or Unrealized Loss under Section 5.5(d) hereof or an allocation of Net Termination Gain or Net Termination Loss pursuant to Section 6.1(c) hereof) as a result of a sale or other taxable disposition of any Partnership asset that is an Adjusted Property (“Disposed of Adjusted Property”), the General Partner shall allocate (1) additional items of gross income and gain (aa) away from the holders of Incentive Distribution Rights and (bb) to the Unitholders, or (2) additional items of deduction and loss (aa) away from the Unitholders and (bb) to the holders of Incentive Distribution Rights, to the extent that the Additional Book Basis Derivative Items allocated to the Unitholders exceed their Share of Additional Book Basis Derivative Items with respect to such Disposed of Adjusted Property. Any allocation made pursuant to this Section 6.1(d)(xii)(B) shall be made after all of the other Agreed Allocations have been made as if this Section 6.1(d)(xii) were not in this Agreement and, to the extent necessary, shall require the reallocation of items that have been allocated pursuant to such other Agreed Allocations.

(C)In the case of any negative adjustments to the Capital Accounts of the Partners resulting from a Book-Down Event or from the recognition of a Net Termination Loss, such negative adjustment (1) shall first be allocated, to the extent of the Aggregate Remaining Net Positive Adjustments, in such a manner, as determined by the General Partner, that to the extent possible the aggregate Capital Accounts of the Partners will equal the amount that would have been the Capital Account balances of the Partners if no prior Book-Up Events had occurred, and (2) any negative adjustment in excess of the Aggregate Remaining Net Positive Adjustments shall be allocated pursuant to Section 6.1(c) hereof.

(D)For purposes of this Section 6.1(d)(xii), the Unitholders shall be treated as being allocated Additional Book Basis Derivative Items to the extent that such Additional Book Basis Derivative Items have reduced the amount of income that would otherwise have been allocated to the Unitholders under this Agreement. In making the allocations required under this Section 6.1(d)(xii), the General Partner may apply whatever conventions or other methodology it determines will satisfy the purpose of this Section 6.1(d)(xii). Without limiting the foregoing, if an Adjusted Property is contributed by the Partnership to another entity classified as a partnership for federal income tax purposes (the “lower tier partnership”), the General Partner may make allocations similar to those described in Sections 6.1(d)(xii)(A)-(C) to the extent the General Partner determines such allocations are necessary to account for the Partnership's allocable share of income, gain, loss and deduction of the lower tier partnership that relate to the contributed Adjusted Property in a manner that is consistent with the purpose of this Section 6.1(d)(xii).

73

(E)Notwithstanding any other provision of this Section 6.1(d)(xii), (x) no allocations shall be made pursuant to this Section 6.1(d)(xii) with respect to any taxable period (or portion thereof) ending on or prior to the IPO Closing Date and (y) for taxable periods (or portions thereof) ending after the IPO Closing Date, the determinations of Additional Book Basis (and items derived therefrom) and Net Positive Adjustments (and items derived therefrom) shall be made without regard to any Book-Up Event or Book-Down Event that occurred on or prior to the IPO Closing Date.

(xiii)Special Curative Allocation in Event of Liquidation Prior to End of Subordination Period. Notwithstanding any other provision of this Section 6.1 (other than the Required Allocations), if the Liquidation Date occurs after the IPO Closing Date and prior to the conversion of the last Outstanding Subordinated Unit, then items of income, gain, loss and deduction for the taxable period that includes the Liquidation Date (and, if necessary, items arising in previous taxable periods to the extent the General Partner determines such items may be so allocated), shall be specially allocated among the Partners in the manner determined appropriate by the General Partner so as to cause, to the maximum extent possible, the Capital Account in respect of each Common Unit to equal the amount such Capital Account would have been if all prior allocations of Net Termination Gain and Net Termination Loss had been made pursuant to Section 6.1(c)(i) or Section 6.1(c)(ii), as applicable.

Section 6.2    Allocations for Tax Purposes.

(a)Except as otherwise provided herein, for federal income tax purposes, each item of income, gain, loss and deduction shall be allocated among the Partners in the same manner as its correlative item of “book” income, gain, loss or deduction is allocated pursuant to Section 6.1.

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

(c)The General Partner may determine to depreciate or amortize the portion of an adjustment under Section 743(b) of the Code attributable to unrealized appreciation in any Adjusted Property (to the extent of the unamortized Book-Tax Disparity) using a predetermined rate derived from the depreciation or amortization method and useful life applied to the unamortized Book-Tax Disparity of such property, despite any inconsistency of such approach with Treasury Regulation Section 1.167(c)-l(a)(6) or any successor regulations thereto. If the General Partner determines that such reporting position cannot reasonably be taken, the General Partner may adopt depreciation and amortization conventions under which all purchasers acquiring Limited Partner Interests in the same month would receive depreciation and amortization deductions, based upon the same applicable rate as if they had purchased a direct

74

interest in the Partnership's property. If the General Partner chooses not to utilize such aggregate method, the General Partner may use any other depreciation and amortization conventions to preserve the uniformity of the intrinsic tax characteristics of any Limited Partner Interests, so long as such conventions would not have a material adverse effect on the Limited Partners or the Record Holders of any class or classes of Limited Partner Interests.

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

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

(f)Each item of Partnership income, gain, loss and deduction shall, for federal income tax purposes, be determined for each taxable period and prorated on a monthly basis and shall be allocated to the Partners as of the opening of the first Business Day of each month; provided, however, that gain or loss on a sale or other disposition of any assets of the Partnership or any other extraordinary item of income, gain, loss or deduction as determined by the General Partner, shall be allocated to the Partners as of the opening of the first Business Day of the month in which such item is recognized for federal income tax purposes. The General Partner may revise, alter or otherwise modify such methods of allocation to the extent permitted or required by Section 706 of the Code and the regulations or rulings promulgated thereunder.

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

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

(a)Within 45 days following the end of each Quarter commencing with the Quarter ended on June 30, 2013, an amount equal to 100% of Distributable Cash (before the IPO Closing Date) or 100% of Available Cash (on and after the IPO Closing Date) with respect to such Quarter shall be distributed in accordance with this Article VI by the Partnership to the Partners as of the Record Date selected by the General Partner. After the IPO Closing Date, all amounts of Available Cash distributed by the Partnership on any date from any source shall be deemed to be Operating Surplus until the sum of all amounts of Available Cash theretofore distributed by the Partnership to the Partners pursuant to Section 6.5 equals the Operating Surplus from the

75

Closing Date through the close of the immediately preceding Quarter. Any remaining amounts of Available Cash distributed by the Partnership on such date shall, except as otherwise provided in Section 6.6, be deemed to be “Capital Surplus.” All distributions required to be made under this Agreement shall be made subject to Sections 17-607 and 17-804 of the Delaware Act.

(b)With respect to the distribution for the Quarter in which the Initial Public Offering occurs:

(i)the amount of Distributable Cash distributed to the Partners shall equal 100% of the Distributable Cash with respect to such Quarter multiplied by a fraction of which the numerator is the number of days in the period commencing on the first day of such Quarter and ending on the day prior to the IPO Closing Date and of which the denominator is the number of days in such Quarter, which amount of Distributable Cash shall be distributed to the Partners immediately prior to the closing of the Initial Public Offering in accordance with Section 6.3(a); and

(ii)the amount of Available Cash distributed to the Partners shall equal 100% of the Available Cash with respect to such Quarter multiplied by a fraction of which the numerator is the number of days in the period commencing on the IPO Closing Date and ending on the last day of such Quarter and of which the denominator is the number of days in such Quarter, which amount of Available Cash shall be distributed to the Partners in accordance with Section 6.3(a).

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

(d)The General Partner may treat taxes paid by the Partnership on behalf of, or amounts withheld with respect to, all or less than all of the Partners, as a distribution of Distributable Cash (if before the IPO Closing Date) or Available Cash (if on or after the IPO Closing Date) to such Partners, as determined appropriate under the circumstances by the General Partner.

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

Section 6.4    Distributions of Distributable Cash Prior to the Initial Public Offering.

(a)Prior to the date that is 18 months after the Closing, Distributable Cash with respect to any Quarter (or portion thereof) prior to the IPO Closing Date shall be distributed to the Unitholders, Pro Rata.

76

(b)On and after the date that is 18 months after the Closing, Distributable Cash with respect to any Quarter (or portion thereof) prior to the IPO Closing Date shall be distributed as follows:

(i)First, to the holders of the Bronco Units until such holders receive the greater of (A) their Pro Rata share of such Distributable Cash and (B) the Minimum Bronco Pre-IPO MQD Amount per Bronco Unit (or with respect to periods of less than a full Quarter, the product of such amount multiplied by a fraction of which the numerator is the number of days in such period and the denominator is the total number of days in such Quarter) (the “BroncoPre-IPO MQD”);

(ii)Second, to the holders of the Bronco Units until all Bronco Arrearage Amounts then outstanding have been paid in full;

(iii)Third, to the holders of the CERC Units until such holders receive their Pro Rata share of such Distributable Cash (the “CERC Distributable Amount”); and

(iv)Fourth, to the holders of the OGEH Units until such holders receive their Pro Rata share of such Distributable Cash (the “OGEH Distributable Amount”).

In the event that Distributable Cash is not sufficient to pay the Bronco Pre-IPO MQD with respect to a Quarter, the amount of the Bronco Pre-IPO MQD that is not paid with respect to such Quarter (the “Bronco Arrearage Amount”) shall carry forward and be paid to the holders of the Bronco Units as a special distribution (A) from time to time in accordance with Section 6.4(b) in the priority set forth therein and (B) to the extent then outstanding, on the earlier of (1) the IPO Closing Date and (2) the dissolution and liquidation of the Partnership; provided that in any event the Bronco Arrearage Amount shall be distributed in full prior to any distributions made with respect to the CERC Arrearage Amount or the OGEH Arrearage Amount.

In the event that Distributable Cash is not sufficient to pay the CERC Distributable Amount with respect to a Quarter, the amount of the CERC Distributable Amount that is not paid with respect to such Quarter (the “CERC Arrearage Amount”) shall carry forward and be paid to the holders of the CERC Units as a special distribution, to the extent then outstanding, on the earlier of (1) the IPO Closing Date and (2) the dissolution and liquidation of the Partnership; provided that in any event the CERC Arrearage Amount shall be distributed in full prior to any distributions made with respect to the OGEH Arrearage Amount.

In the event that Distributable Cash is not sufficient to pay the OGEH Distributable Amount with respect to a Quarter, the amount of the OGEH Distributable Amount that is not paid with respect to such Quarter (the “OGEH Arrearage Amount”) shall carry forward and be paid to the holders of the OGEH Units as a special distribution, to the extent then outstanding, on the earlier of (1) the IPO Closing Date and (2) the dissolution and liquidation of the Partnership.

77

Section 6.5    Distributions of Available Cash from Operating Surplus After the IPO Closing Date.

(a)During the Subordination Period. Available Cash with respect to any Quarter (or portion thereof) after the IPO Closing Date and within the Subordination Period that is deemed to be Operating Surplus pursuant to the provisions of Section 6.3 or 6.6 shall be distributed as follows, except as otherwise required in respect of additional Partnership Interests issued pursuant to Section 5.6(b):

(i)First, to the Unitholders holding Common Units, Pro Rata, until there has been distributed in respect of each Common Unit then Outstanding an amount equal to the Minimum Quarterly Distribution for such Quarter;

(ii)Second, to the Unitholders holding Common Units, Pro Rata, until there has been distributed in respect of each Common Unit then Outstanding an amount equal to the Cumulative Common Unit Arrearage existing with respect to such Quarter;

(iii)Third, to the Unitholders holding Subordinated Units, Pro Rata, until there has been distributed in respect of each Subordinated Unit then Outstanding an amount equal to the Minimum Quarterly Distribution for such Quarter;

(iv)Fourth, to all Unitholders, Pro Rata, until there has been distributed in respect of each Unit then Outstanding an amount equal to the excess of the First Target Distribution over the Minimum Quarterly Distribution for such Quarter;

(v)Fifth, (A) 15% to the holders of the Incentive Distribution Rights, Pro Rata, and (B) 85% to all Unitholders, Pro Rata, until there has been distributed in respect of each Unit then Outstanding an amount equal to the excess of the Second Target Distribution over the First Target Distribution for such Quarter;

(vi)Sixth, (A) 25% to the holders of the Incentive Distribution Rights, Pro Rata, and (B) 75% to all Unitholders, Pro Rata, until there has been distributed in respect of each Unit then Outstanding an amount equal to the excess of the Third Target Distribution over the Second Target Distribution for such Quarter; and

(vii)Thereafter, (A) 50% to the holders of the Incentive Distribution Rights, Pro Rata, and (B) 50% to all Unitholders, Pro Rata;

provided, however, if the Minimum Quarterly Distribution, the First Target Distribution, the Second Target Distribution and the Third Target Distribution have been reduced to zero pursuant to the second sentence of Section 6.7(a), the distribution of Available Cash that is deemed to be Operating Surplus with respect to any Quarter will be made solely in accordance with Section 6.5(a)(vii).

(b)After the Subordination Period. Available Cash with respect to any Quarter after the Subordination Period (which Quarter may include the date on which the Subordination Period ends) that is deemed to be Operating Surplus pursuant to the provisions of Section 6.3 or

78

Section 6.6 shall be distributed as follows, except as otherwise required in respect of additional Partnership Interests issued pursuant to Section 5.6(b):

(i)First, to all Unitholders, Pro Rata, until there has been distributed in respect of each Unit then Outstanding an amount equal to the Minimum Quarterly Distribution for such Quarter;

(ii)Second, to all Unitholders, Pro Rata, until there has been distributed in respect of each Unit then Outstanding an amount equal to the excess of the First Target Distribution over the Minimum Quarterly Distribution for such Quarter;

(iii)Third, (A) 15% to the holders of the Incentive Distribution Rights, Pro Rata, and (B) 85% to all Unitholders, Pro Rata, until there has been distributed in respect of each Unit then Outstanding an amount equal to the excess of the Second Target Distribution over the First Target Distribution for such Quarter;

(iv)Fourth, (A) 25% to the holders of the Incentive Distribution Rights, Pro Rata, and (B) 75% to all Unitholders, Pro Rata, until there has been distributed in respect of each Unit then Outstanding an amount equal to the excess of the Third Target Distribution over the Second Target Distribution for such Quarter; and

(v)Thereafter, (A) 50% to the holders of the Incentive Distribution Rights, Pro Rata, and (B) 50% to all Unitholders, Pro Rata;

provided, however, if the Minimum Quarterly Distribution, the First Target Distribution, the Second Target Distribution and the Third Target Distribution have been reduced to zero pursuant to the second sentence of Section 6.7(a), the distribution of Available Cash that is deemed to be Operating Surplus with respect to any Quarter will be made solely in accordance with Section 6.5(b)(v).

Section 6.6    Distributions of Available Cash from Capital Surplus After the IPO Closing Date. Available Cash that is deemed to be Capital Surplus pursuant to the provisions of Section 6.3(a) shall be distributed, unless the provisions of Section 6.3 require otherwise, to the Unitholders, Pro Rata, until the Minimum Quarterly Distribution has been reduced to zero pursuant to the second sentence of Section 6.7(a). Available Cash that is deemed to be Capital Surplus shall then be distributed to all Unitholders holding Common Units, Pro Rata, until there has been distributed in respect of each Common Unit then Outstanding an amount equal to the Cumulative Common Unit Arrearage. Thereafter, all Available Cash shall be distributed as if it were Operating Surplus and shall be distributed in accordance with Section 6.5.

Section 6.7    Adjustment of Minimum Quarterly Distribution and Target Distribution Levels.

(a)The Minimum Quarterly Distribution, Target Distributions, Common Unit Arrearages and Cumulative Common Unit Arrearages shall be proportionately adjusted in the event of any distribution, combination or subdivision (whether effected by a distribution payable in Units or otherwise) of Units or other Partnership Interests in accordance with Section 5.10. In the event of a distribution of Available Cash that is deemed to be from Capital Surplus, the then

79

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

(b)The Minimum Quarterly Distribution, First Target Distribution, Second Target Distribution and Third Target Distribution, shall also be subject to adjustment pursuant to Section 5.12 and Section 6.10.

Section 6.8    Special Provisions Relating to the Holders of Subordinated Units.

(a)Except with respect to the right to vote on or approve matters requiring the vote or approval of a percentage of the holders of Outstanding Common Units and the right to participate in allocations of income, gain, loss and deduction and distributions made with respect to Common Units, the holder of a Subordinated Unit shall have all of the rights and obligations of a Unitholder holding Common Units hereunder; provided, however, that immediately upon the conversion of Subordinated Units into Common Units pursuant to Section 5.8, the Unitholders holding a Subordinated Unit shall possess all of the rights and obligations of a Unitholder holding Common Units hereunder with respect to such converted Subordinated Units, including the right to vote as a Common Unitholder and the right to participate in allocations of income, gain, loss and deduction and distributions made with respect to Common Units; provided, however, that such converted Subordinated Units shall remain subject to the provisions of Section 5.5(c)(ii), Section 6.1(d)(x)(A), Section 6.8(b) and Section 6.8(c).

(b)A Unitholder shall not be permitted to transfer a Subordinated Unit or a Subordinated Unit that has converted into a Common Unit pursuant to Section 5.8 (other than a transfer to an Affiliate) if the remaining balance in the transferring Unitholder's Capital Account with respect to the retained Subordinated Units or Retained Converted Subordinated Units would be negative after giving effect to the allocation under Section 5.5(c)(ii).

(c)The holder of a Common Unit that has resulted from the conversion of a Subordinated Unit pursuant to Section 5.8 shall not be issued a Common Unit Certificate pursuant to Section 4.1 (if the Common Units are represented by Certificates) and shall not be permitted to transfer such Common Unit to a Person that is not an Affiliate of the holder until such time as the General Partner determines, based on advice of counsel, that each such Common Unit should have, as a substantive matter, like intrinsic economic and federal income tax characteristics, in all material respects, to the intrinsic economic and federal income tax characteristics of an IPO Common Unit. In connection with the condition imposed by this Section 6.8(c), the General Partner may take whatever steps are required to provide economic uniformity to such Common Units in preparation for a transfer of such Common Units, including the application of Section 5.5(c)(ii) and Section 6.1(d)(x); provided, however, that no such steps may be taken that would have a material adverse effect on the Unitholders holding Common Units.

Section 6.9    Special Provisions Relating to the Holders of Incentive Distribution Rights.

(a)Notwithstanding anything to the contrary set forth in this Agreement, the holders of the Incentive Distribution Rights (1) shall (x) possess the rights and obligations provided in this Agreement with respect to a Limited Partner pursuant to Article III and Article VII and (y) have a Capital Account as a Partner pursuant to Section 5.5 and all other provisions related thereto and (2) shall not (x) be entitled to vote on any matters requiring the approval or vote of the holders of Outstanding Units, except as provided by law, (y) be entitled to any distributions other than as provided in Sections 6.5(a)(v), (vi) and (vii), Sections 6.5(b)(iii), (iv) and (v), and Section 12.4 or (z) be allocated items of income, gain, loss or deduction other than as specified in this Article VI; provided, however, that, for the avoidance of doubt, the foregoing shall not preclude the Partnership from making any other payments or distributions in connection with other actions permitted by this Agreement.

(b)A Unitholder shall not be permitted to transfer an IDR Reset Common Unit (other than a transfer to an Affiliate) if the remaining balance in the transferring Unitholder's Capital Account with respect to the retained IDR Reset Common Units would be negative after giving effect to the allocation under Section 5.5(c)(iii).

(c)A holder of an IDR Reset Common Unit that was issued in connection with an IDR Reset Election pursuant to Section 5.12 shall not be issued a Common Unit Certificate pursuant to Section 4.1 (if the Common Units are evidenced by Certificates) or evidence of the issuance of uncertificated Common Units, and shall not be permitted to transfer such Common Unit to a Person that is not an Affiliate of such holder, until such time as the General Partner determines, based on advice of counsel, that each such IDR Reset Common Unit should have, as a substantive matter, like intrinsic economic and federal income tax characteristics, in all material respects, to the intrinsic economic and federal income tax characteristics of an IPO Common Unit. In connection with the condition imposed by this Section 6.9(c), the General Partner may take whatever steps are required to provide economic uniformity to such IDR Reset Common Units in preparation for a transfer of such IDR Reset Common Units, including the application of Section 5.5(c)(iii), Section 6.1(d)(x)(B), or Section 6.1(d)(x)(C); provided, however, that no such steps may be taken that would have a material adverse effect on the Unitholders holding Common Units.

Section 6.10    Entity-Level Taxation. If legislation is enacted or the official interpretation of existing legislation is modified by a governmental authority, which after giving effect to such enactment or modification, results in a Group Member becoming subject to federal, state or local or non-U.S. income or withholding taxes in excess of the amount of such taxes due from the Group Member prior to such enactment or modification (including, for the avoidance of doubt, any increase in the rate of such taxation applicable to the Group Member), then the General Partner shall reduce the Minimum Quarterly Distribution, the Target Distributions, the Minimum Bronco Pre-IPO MQD Amount and Distributable Cash by the amount of income or withholding taxes that are payable by reason of any such new legislation or interpretation (the “Incremental Income Taxes”) in the manner provided in this Section 6.10. If in accordance with the foregoing the General Partner reduces the Minimum Quarterly Distribution, the Target Distributions, the Minimum Bronco Pre-IPO MQD Amount and

81

Distributable Cash for any Quarter with respect to any Incremental Income Taxes, the General Partner shall estimate for such Quarter the Partnership Group's aggregate liability (the “Estimated Incremental Quarterly Tax Amount”) for all such Incremental Income Taxes; provided that any difference between such estimate and the actual liability for Incremental Income Taxes for such Quarter may, to the extent determined by the General Partner, be taken into account in determining the Estimated Incremental Quarterly Tax Amount with respect to each Quarter in which any such difference can be determined. For each such Quarter, the Minimum Bronco Pre-IPO MQD Amount, Distributable Cash, Minimum Quarterly Distribution, First Target Distribution, Second Target Distribution and Third Target Distribution, shall be the product obtained by multiplying (a) the amounts therefor that are set out herein prior to the application of this Section 6.10 times (b) the quotient obtained by dividing (i) in the case of Distributable Cash and the Minimum Bronco Pre-IPO MQD Amount, (A) Distributable Cash with respect to such Quarter by (B) the sum of Distributable Cash with respect to such Quarter and the Estimated Incremental Quarterly Tax Amount for such Quarter, as determined by the General Partner and (ii) in all other cases, (A) Available Cash with respect to such Quarter by (B) the sum of Available Cash with respect to such Quarter and the Estimated Incremental Quarterly Tax Amount for such Quarter, as determined by the General Partner. For purposes of the foregoing, Distributable Cash and Available Cash with respect to a Quarter will be deemed reduced by the Estimated Incremental Quarterly Tax Amount for that Quarter.

Section 7.2    Certificate of Limited Partnership. The General Partner has caused the Certificate of Limited Partnership to be filed with the Secretary of State of the State of Delaware as required by the Delaware Act. The General Partner shall use all reasonable efforts to cause to be filed such other certificates or documents that the General Partner determines to be necessary or appropriate for the formation, continuation, qualification and operation of a limited partnership (or a partnership in which the limited partners have limited liability) in the State of Delaware or any other state in which the Partnership may elect to do business or own property. To the extent the General Partner determines such action to be necessary or appropriate, the General Partner shall file amendments to and restatements of the Certificate of Limited Partnership and do all things to maintain the Partnership as a limited partnership (or a partnership or other entity in which the limited partners have limited liability) under the laws of the State of Delaware or of any other state in which the Partnership may elect to do business or own property. Subject to the terms of Section 3.3(a), the General Partner shall not be required, before or after filing, to deliver or mail a copy of the Certificate of Limited Partnership, any qualification document or any amendment thereto to any Limited Partner.

84

Section 7.3    Restrictions on the General Partner's Authority to Sell Assets of the Partnership Group. Except as provided in Article XII and Article XIV, the General Partner may not sell, exchange or otherwise dispose of all or substantially all of the assets of the Partnership Group, taken as a whole, in a single transaction or a series of related transactions without the approval of holders of a Unit Majority; provided, however, that this provision shall not preclude or limit the General Partner's ability to mortgage, pledge, hypothecate or grant a security interest in all or substantially all of the assets of the Partnership Group and shall not apply to any forced sale of any or all of the assets of the Partnership Group pursuant to the foreclosure of, or other realization upon, any such encumbrance.

Section 7.4    Reimbursement of the General Partner.

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

(b)The General Partner shall be reimbursed on a monthly basis, or such other basis as the General Partner may determine, for (i) all payments it makes on behalf of the Partnership Group for salary, bonus, incentive compensation and other amounts paid to any Person who is an employee of the General Partner that manages the business and affairs of the Partnership Group, and (ii) all other overhead and general and administrative expenses allocable to the Partnership Group that are incurred by the General Partner in connection with the General Partner's management of the Partnership Group's business and affairs (including expenses allocated to the General Partner by its Affiliates), subject to a maximum of $500,000 per calendar year (which shall be pro rated for partial years) prior to the Bronco Fall-Away Date, other than those performed under the Transition Services Agreements. The General Partner shall determine the expenses that are allocable to the Partnership Group. Reimbursements pursuant to this Section 7.4 shall be in addition to any reimbursement to the General Partner as a result of indemnification pursuant to Section 7.7. This provision does not affect the ability of the General Partner and its Affiliates to enter into an agreement to provide services to any Group Member for a fee or otherwise than for cost.

(c)The General Partner, without the approval of the Limited Partners (who shall have no right to vote in respect thereof, other than as set forth in Section 3.4(a)), may propose and adopt on behalf of the Partnership employee benefit plans, employee programs and employee practices (including plans, programs and practices involving the issuance of Partnership Interests or options to purchase or rights, warrants or appreciation rights or phantom or tracking interests relating to Partnership Interests), or cause the Partnership to issue Partnership Interests or Derivative Partnership Interests in connection with, or pursuant to, any employee benefit plan, employee program or employee practice maintained or sponsored by the General Partner or any of its Affiliates in each case for the benefit of employees and directors of the General Partner or any of its Affiliates, in respect of services performed, directly or indirectly, for the benefit of the Partnership Group. The Partnership agrees to issue and sell to the General Partner or any of its Affiliates any Partnership Interests or Derivative Partnership Interests that the General Partner or such Affiliates are obligated to provide to any employees, consultants and directors pursuant to any such employee benefit plans, employee programs or employee practices. Expenses incurred by the General Partner in connection with any such plans, programs and practices (including the

85

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

(d)The General Partner and its Affiliates may charge any member of the Partnership Group a management fee to the extent necessary to allow the Partnership Group to reduce the amount of any state franchise or income tax or any tax based upon the revenues or gross margin of any member of the Partnership Group if the tax benefit produced by the payment of such management fee or fees exceeds the amount of such fee or fees.

Section 7.5    Outside Activities.

(a)The General Partner, for so long as it is the General Partner of the Partnership, (i) agrees that its sole business will be to act as a general partner or managing member, as the case may be, of the Partnership and any other partnership or limited liability company of which the Partnership is, directly or indirectly, a partner or member and to undertake activities that are ancillary or related thereto (including being a Limited Partner in the Partnership) and (ii) shall not engage in any business or activity or incur any debts or liabilities except in connection with or incidental to (A) its performance as general partner or managing member, if any, of one or more Group Members or as described in or contemplated by this Agreement, (B) the acquiring, owning or disposing of debt securities or equity interests in any Group Member or (C) subject to the limitations contained in the Omnibus Agreement, the performance of its obligations under the Omnibus Agreement.

(b) Except as provided in the Omnibus Agreement, Section 3.4(a) or any Group Member Agreement, each Unrestricted Person (other than the General Partner) shall have the right to engage in businesses of every type and description and other activities for profit and to engage in and possess an interest in other business ventures of any and every type or description, whether in businesses engaged in or anticipated to be engaged in by any Group Member, independently or with others, including business interests and activities in direct competition with the business and activities of any Group Member, and none of the same shall constitute a breach of this Agreement or any duty otherwise existing at law, in equity or otherwise, to any Group Member or any Partner; provided such Unrestricted Person does not engage in such business or activity using confidential or proprietary information provided by or on behalf of the Partnership to such Unrestricted Person. None of any Group Member, any Limited Partner or any other Person shall have any rights by virtue of this Agreement, any Group Member Agreement, or the partnership relationship established hereby in any business ventures of any Unrestricted Person.

(c)Subject to the terms of Sections 7.5(a) and (b), but otherwise notwithstanding anything to the contrary in this Agreement, (i) the engaging in competitive activities by any

86

Unrestricted Person (other than the General Partner) in accordance with the provisions of this Section 7.5 is hereby approved by the Partnership and all Partners, (ii) it shall be deemed not to be a breach of any duty otherwise existing at law, in equity or otherwise, of the General Partner or any other Unrestricted Person for the Unrestricted Persons (other than the General Partner) to engage in such business interests and activities in preference to or to the exclusion of the Partnership and (iii) the Unrestricted Persons shall have no obligation hereunder or as a result of any duty otherwise existing at law, in equity or otherwise, to present business opportunities to the Partnership. Notwithstanding anything to the contrary in this Agreement, the doctrine of corporate opportunity, or any analogous doctrine, shall not apply to any Unrestricted Person (including the General Partner). Except as provided in the Omnibus Agreement or any Group Member Agreement, no Unrestricted Person (including the General Partner) who acquires knowledge of a potential transaction, agreement, arrangement or other matter that may be an opportunity for the Partnership, shall have any duty to communicate or offer such opportunity to the Partnership, and such Unrestricted Person (including the General Partner) shall not be liable to the Partnership, to any Limited Partner or any other Person bound by this Agreement for breach of any duty otherwise existing at law, in equity or otherwise, by reason of the fact that such Unrestricted Person (including the General Partner) pursues or acquires for itself, directs such opportunity to another Person or does not communicate such opportunity or information to the Partnership, provided such Unrestricted Person does not engage in such business or activity using confidential or proprietary information provided by or on behalf of the Partnership to such Unrestricted Person.

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

(e)Notwithstanding anything to the contrary in this Agreement, to the extent that the provisions of this Agreement purport or are interpreted to have the effect of restricting or eliminating any duties (including fiduciary duties) otherwise existing at law, in equity or otherwise, owed by the General Partner or other Person to the Partnership, its Limited Partners or any other Person bound by this Agreement or to constitute a waiver or consent by the Limited Partners or any other Person bound by this Agreement to any such restriction, such provisions shall be deemed to have been approved by the Partners and every other Person bound by this Agreement.

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

(a)Subject to Section 3.4(a), the General Partner or any of its Affiliates may lend to any Group Member, and any Group Member may borrow from the General Partner or any of its Affiliates, funds needed or desired by the Group Member for such periods of time and in such amounts as the General Partner may determine; provided, however, that in any such case the lending party may not charge the borrowing party interest at a rate greater than the rate that would be charged the borrowing party or impose terms less favorable to the borrowing party than would be charged or imposed on the borrowing party by unrelated lenders on comparable loans

87

made on an arm's-length basis (without reference to the lending party's financial abilities or guarantees), all as determined by the General Partner. The borrowing party shall reimburse the lending party for any costs (other than any additional interest costs) incurred by the lending party in connection with the borrowing of such funds. For purposes of this Section 7.6(a) and Section 7.6(b), the term “Group Member” shall include any Affiliate of a Group Member that is controlled by the Group Member.

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

(c)No borrowing by any Group Member or the approval thereof by the General Partner shall be deemed to constitute a breach of any duty or any other obligation of any type whatsoever, expressed or implied, of the General Partner or its Affiliates to the Partnership or the Limited Partners existing hereunder, or existing at law, in equity or otherwise by reason of the fact that the purpose or effect of such borrowing is directly or indirectly to hasten the expiration of the Subordination Period or the conversion of any Subordinated Units into Common Units.

Section 7.7    Indemnification.

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

(b)To the fullest extent permitted by law, expenses (including legal fees and expenses) incurred by an Indemnitee who is indemnified pursuant to Section 7.7(a) in appearing at, participating in or defending any claim, demand, action, suit or proceeding shall, from time to time, be advanced by the Partnership prior to a final and non-appealable judgment entered by a

88

court of competent jurisdiction determining that, in respect of the matter for which the Indemnitee is seeking indemnification pursuant to this Section 7.7, the Indemnitee is not entitled to be indemnified upon receipt by the Partnership of any undertaking by or on behalf of the Indemnitee to repay such amount if it shall be ultimately determined that the Indemnitee is not entitled to be indemnified as authorized by this Section 7.7.

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

(d)The Partnership may purchase and maintain (or reimburse the General Partner or its Affiliates for the cost of) insurance, on behalf of the General Partner, its Affiliates and such other Persons as the General Partner shall determine, against any liability that may be asserted against, or expense that may be incurred by, such Person in connection with the Partnership's activities or such Person's activities on behalf of the Partnership, regardless of whether the Partnership would have the power to indemnify such Person against such liability under the provisions of this Agreement.

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

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

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

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

(i)No amendment, modification or repeal of this Section 7.7 or any provision hereof shall in any manner terminate, reduce or impair the right of any past, present or future Indemnitee to be indemnified by the Partnership, nor the obligations of the Partnership to

89

indemnify any such Indemnitee under and in accordance with the provisions of this Section 7.7 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted.

(j)TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, AND SUBJECT TO SECTION 7.7(a), THE PROVISIONS OF THE INDEMNIFICATION PROVIDED IN THIS SECTION 7.7 ARE INTENDED BY THE PARTNERS TO APPLY EVEN IF SUCH PROVISIONS HAVE THE EFFECT OF EXCULPATING THE INDEMNITEE FROM LEGAL RESPONSIBILITY FOR THE CONSEQUENCES OF SUCH PERSON'S NEGLIGENCE, FAULT OR OTHER CONDUCT.

Section 7.8    Liability of Indemnitees.

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

(b)The General Partner may exercise any of the powers granted to it by this Agreement and perform any of the duties imposed upon it hereunder either directly or by or through its agents, and the General Partner shall not be responsible for any misconduct or negligence on the part of any such agent appointed by the General Partner in good faith.

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

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

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

(a)Unless otherwise expressly provided in this Agreement or any Group Member Agreement, whenever a potential conflict of interest exists or arises between the General Partner or any of its Affiliates, on the one hand, and the Partnership, any Group Member or any Partner, on the other, any resolution or course of action by the General Partner or its Affiliates in respect

90

of such conflict of interest shall be permitted and deemed approved by all Partners, and shall not constitute a breach of this Agreement, of any Group Member Agreement, of any agreement contemplated herein or therein, or of any duty stated or implied by law or equity, if the resolution or course of action in respect of such conflict of interest is (i) approved by Special Approval, (ii) approved by the vote of a majority of the Outstanding Common Units (excluding Common Units owned by the General Partner and its Affiliates), (iii) determined by the Board of Directors of the General Partner to be on terms no less favorable to the Partnership than those generally being provided to or available from unrelated third parties or (iv) determined by the Board of Directors of the General Partner to be fair and reasonable to the Partnership, taking into account the totality of the relationships between the parties involved (including other transactions that may be particularly favorable or advantageous to the Partnership). The General Partner shall be authorized but not required in connection with its resolution of such conflict of interest to seek Special Approval or Unitholder approval of such resolution, and the General Partner may also adopt a resolution or course of action that has not received Special Approval or Unitholder approval. Unless otherwise expressly provided in this Agreement or any Group Member Agreement, whenever the General Partner makes a determination to refer any potential conflict of interest for Special Approval, seek Unitholder Approval or adopt a resolution or course of action that has not received Special Approval or Unitholder Approval, then the General Partner shall be entitled, to the fullest extent permitted by law, to make such determination or to take or decline to take such other action free of any duty or obligation whatsoever to the Partnership or any Limited Partner, and the General Partner shall not, to the fullest extent permitted by law, be required to act in good faith or pursuant to any other standard imposed by this Agreement, any Group Member Agreement, any other agreement contemplated hereby or under the Delaware Act or any other law, rule or regulation or at equity, and the General Partner in making such determination or taking or declining to take such other action shall be permitted to do so in its sole and absolute discretion. If Special Approval is sought, then it shall be presumed that, in making its decision, the disinterested directors or the Conflicts Committee, as the case may be, acted in good faith, and if the Board of Directors of the General Partner determines that the resolution or course of action taken with respect to a conflict of interest satisfies either of the standards set forth in clauses (iii) or (iv) above, then it shall be presumed that, in making its decision, the Board of Directors of the General Partner acted in good faith. In any proceeding brought by any Limited Partner or by or on behalf of such Limited Partner or any other Limited Partner or the Partnership challenging any action by the disinterested directors or the Conflicts Committee, as the case may be, with respect to any matter referred to the disinterested directors or the Conflicts Committee, as the case may be, for Special Approval by the General Partner, any action by the Board of Directors of the General Partner in determining whether the resolution or course of action taken with respect to a conflict of interest satisfies either of the standards set forth in clauses (iii) or (iv) above or whether a director satisfies the eligibility requirements to be a disinterested director or a member of the Conflicts Committee, as the case may be, the Person bringing or prosecuting such proceeding shall have the burden of overcoming the presumption that the disinterested directors, Conflicts Committee or the Board of Directors of the General Partner, as applicable, acted in good faith; in all cases subject to the provisions for conclusive determination in Section 7.9(b).

(b)Whenever the General Partner or the Board of Directors, or any committee thereof (including the Conflicts Committee), makes a determination or takes or declines to take any other action, or any Affiliate of the General Partner causes the General Partner to do so, in its

91

capacity as the general partner of the Partnership as opposed to in its individual capacity, whether under this Agreement, any Group Member Agreement or any other agreement, then, unless another express standard is provided for in this Agreement, the General Partner, the Board of Directors or such committee or such Affiliates causing the General Partner to do so, shall make such determination or take or decline to take such other action in good faith and shall not be subject to any other or different standards (including fiduciary standards) imposed by this Agreement, any Group Member Agreement, any other agreement contemplated hereby or under the Delaware Act or any other law, rule or regulation or at equity. A determination or other action or inaction will conclusively be deemed to be in “good faith” for all purposes of this Agreement, if the Person or Persons making such determination or taking or declining to take such other action subjectively believe that the determination or other action or inaction is in the best interests of the Partnership Group; provided, that if the Board of Directors of the General Partner is making a determination or taking or declining to take an action pursuant to clause (iii) or clause (iv) of the first sentence of Section 7.9(a), then in lieu thereof, such determination or other action or inaction will conclusively be deemed to be in “good faith” for all purposes of this Agreement if the members of the Board of Directors of the General Partner making such determination or taking or declining to take such other action subjectively believe that the determination or other action or inaction meets the standard set forth in clause (iii) or clause (iv) of the first sentence of Section 7.9(a), as applicable; provided, further, that if the Board of Directors of the General Partner is making a determination that a director satisfies the eligibility requirements to be a disinterested director or a member of a Conflicts Committee, as the case may be, then in lieu thereof, such determination will conclusively be deemed to be in “good faith” for all purposes of this Agreement if the members of the Board of Directors of the General Partner making such determination subjectively believe that the director satisfies the eligibility requirements to be a disinterested director or a member of the Conflicts Committee, as the case may be.

(c)Whenever the General Partner makes a determination or takes or declines to take any other action, or any of its Affiliates causes it to do so, in its individual capacity as opposed to in its capacity as the general partner of the Partnership, whether under this Agreement, any Group Member Agreement or any other agreement contemplated hereby or otherwise, then the General Partner, or such Affiliates causing it to do so, are entitled, to the fullest extent permitted by law, to make such determination or to take or decline to take such other action free of any duty or obligation whatsoever to the Partnership or any Limited Partner, and the General Partner, or such Affiliates causing it to do so, shall not, to the fullest extent permitted by law, be required to act in good faith or pursuant to any other standard imposed by this Agreement, any Group Member Agreement, any other agreement contemplated hereby or under the Delaware Act or any other law, rule or regulation or at equity, and the Person or Persons making such determination or taking or declining to take such other action shall be permitted to do so in their sole and absolute discretion. By way of illustration and not of limitation, whenever the phrase, “the General Partner at its option,” or some variation of that phrase, is used in this Agreement, it indicates that the General Partner is acting in its individual capacity. For the avoidance of doubt, whenever the General Partner votes or transfers its Partnership Interests, or refrains from voting or transferring its Partnership Interests, it shall be acting in its individual capacity.

(d)The General Partner's organizational documents may provide that determinations to take or decline to take any action in its individual, rather than representative, capacity may or

92

shall be determined by its members, if the General Partner is a limited liability company, stockholders, if the General Partner is a corporation, or the members or stockholders of the General Partner's general partner, if the General Partner is a partnership.

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

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

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

Section 7.10    Other Matters Concerning the General Partner.

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

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

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

Section 7.11    Purchase or Sale of Partnership Interests. The General Partner may cause the Partnership to purchase or otherwise acquire Partnership Interests or Derivative Partnership Interests; provided that, except as permitted pursuant to Section 4.10, the General Partner may

93

not cause any Group Member to purchase Subordinated Units during the Subordination Period. As long as Partnership Interests are held by any Group Member, such Partnership Interests shall not be considered Outstanding for any purpose, except as otherwise provided herein. The General Partner or any Affiliate of the General Partner may also purchase or otherwise acquire and sell or otherwise dispose of Partnership Interests for its own account, subject to the provisions of Articles IV and X.

Section 7.12    Reliance by Third Parties. Notwithstanding anything to the contrary in this Agreement, any Person (other than the General Partner and its Affiliates) dealing with the Partnership shall be entitled to assume that the General Partner and any officer of the General Partner authorized by the General Partner to act on behalf of and in the name of the Partnership has full power and authority to encumber, sell or otherwise use in any manner any and all assets of the Partnership and to enter into any authorized contracts on behalf of the Partnership, and such Person shall be entitled to deal with the General Partner or any such officer as if it were the Partnership's sole party in interest, both legally and beneficially. Each Limited Partner hereby waives, to the fullest extent permitted by law, any and all defenses or other remedies that may be available against such Person to contest, negate or disaffirm any action of the General Partner or any such officer in connection with any such dealing. In no event shall any Person (other than the General Partner and its Affiliates) dealing with the General Partner or any such officer or its representatives be obligated to ascertain that the terms of this Agreement have been complied with or to inquire into the necessity or expedience of any act or action of the General Partner or any such officer or its representatives. Each and every certificate, document or other instrument executed on behalf of the Partnership by the General Partner or its representatives shall be conclusive evidence in favor of any and every Person relying thereon or claiming thereunder that (a) at the time of the execution and delivery of such certificate, document or instrument, this Agreement was in full force and effect, (b) the Person executing and delivering such certificate, document or instrument was duly authorized and empowered to do so for and on behalf of the Partnership and (c) such certificate, document or instrument was duly executed and delivered in accordance with the terms and provisions of this Agreement and is binding upon the Partnership.

Section 7.13    Pension Plan Liabilities. Prior to the IPO Closing Date, the General Partner and the Sponsor Parties shall not permit any Group Member to accept or assume the transfer of assets or liabilities from any pension plan, as defined in Section 3(2) of ERISA, whether or not subject to ERISA, that is sponsored or maintained by either Sponsor Party or its Affiliates. On or after the IPO Closing Date, any acceptance or assumption of assets or liabilities from any such pension plan that is sponsored or maintained by either Sponsor Party or its Affiliates shall be approved by Special Approval. To the fullest extent permitted by law, each Sponsor Party shall indemnify and hold harmless the Partnership and any other Group Member from and against any and all losses, damages, liabilities, claims, demands, causes of action, judgments, settlements, fines, penalties, costs and expenses (including court costs and reasonable attorneys' and experts' fees) of any and every kind or character, known or unknown, fixed or contingent, arising from or related to any acceptance or assumption by any Group Member of assets or liabilities from any pension plan, as defined in Section 3(2) of ERISA, whether or not subject to ERISA, maintained by such Sponsor Party or its Affiliates; provided, however, that notwithstanding anything herein to the contrary, in no event shall a Sponsor Party's indemnification obligations cover or include consequential, indirect, incidental, punitive,

94

exemplary, special or similar damages or lost profits suffered by the Partnership or any other Group Member.

Notwithstanding any other provision herein contained, for the purposes of computing the adjustments under Section 743(b) of the Code, the General Partner shall be authorized (but not required) to adopt a convention whereby the price paid by a transferee of a Limited Partner Interest will be deemed to be the lowest quoted closing price of the Limited Partner Interests on any National Securities Exchange on which such Limited Partner Interests are listed or admitted to trading during the calendar month in which such transfer is deemed to occur pursuant to Section 6.2(f) without regard to the actual price paid by such transferee.

A Person may not become a Limited Partner without acquiring a Limited Partner Interest and becoming the Record Holder of such Limited Partner Interest. The rights and obligations of a Person who is an Ineligible Holder shall be determined in accordance with Section 4.9.

Partner in respect of such Units, including the right to vote, on any matter, and unless the arrangement between such Persons provides otherwise, take all action as a Limited Partner by virtue of being the Record Holder of such Units in accordance with the direction of the Person who is the beneficial owner of such Units, and the Partnership shall be entitled to assume such Record Holder is so acting without further inquiry. The provisions of this Section 10.1(c) are subject to the provisions of Section 4.3.

Any such successor is hereby authorized to and shall, subject to the terms hereof, carry on the business of the members of the Partnership Group without dissolution.

Section 10.3    Amendment of Agreement and Certificate of Limited Partnership. To effect the admission to the Partnership of any Partner, the General Partner shall take all steps necessary or appropriate under the Delaware Act to amend the Register and any other records of the Partnership to reflect such admission and, if necessary, to prepare as soon as practicable an amendment to this Agreement and, if required by law, the General Partner shall prepare and file an amendment to the Certificate of Limited Partnership.

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

(b)Withdrawal of the General Partner from the Partnership upon the occurrence of an Event of Withdrawal shall not constitute a breach of this Agreement under the following circumstances: (i)at any time during the period beginning on the Closing Date and ending at 12:00 midnight, Central Time, on the first day of the first Quarter beginning after the tenth anniversary of the IPO Closing Date, the General Partner voluntarily withdraws by giving at least 90 days' advance notice of its intention to withdraw to the Limited Partners; provided, that prior to the effective date of such withdrawal, the withdrawal is approved by Unitholders holding at least a majority of the Outstanding Common Units (excluding Common Units held by the General Partner and its Affiliates) and the General Partner delivers to the Partnership an Opinion of Counsel (“Withdrawal Opinion of Counsel”) that such withdrawal (following the selection of the successor General Partner) would not result in the loss of the limited liability under the Delaware Act of any Limited Partner or cause any Group Member to be treated as an association taxable as a corporation or otherwise to be taxed as an entity for federal income tax purposes (to

100

the extent not already so treated or taxed); (ii)at any time after 12:00 midnight, Central Time, on the first day of the first Quarter beginning after the tenth anniversary of the IPO Closing Date, the General Partner voluntarily withdraws by giving at least 90 days' advance notice to the Unitholders, such withdrawal to take effect on the date specified in such notice; (iii)at any time that the General Partner ceases to be the General Partner pursuant to Section 11.1(a)(ii) or is removed pursuant to Section 11.2; or (iv)notwithstanding clause (i) of this sentence, at any time that the General Partner voluntarily withdraws by giving at least 90 days' advance notice of its intention to withdraw to the Limited Partners, such withdrawal to take effect on the date specified in the notice, if at the time such notice is given one Person and its Affiliates (other than the General Partner and its Affiliates) own beneficially or of record or control at least 50% of the Outstanding Units. The withdrawal of the General Partner from the Partnership upon the occurrence of an Event of Withdrawal shall also constitute the withdrawal of the General Partner as general partner or managing member, if any, to the extent applicable, of the other Group Members. If the General Partner gives a notice of withdrawal pursuant to Section 11.1(a)(i), the holders of a Unit Majority, may, prior to the effective date of such withdrawal, elect a successor General Partner. The Person so elected as successor General Partner shall automatically become the successor general partner or managing member, to the extent applicable, of the other Group Members of which the General Partner is a general partner or a managing member. Any successor General Partner elected in accordance with the terms of this Section 11.1 shall be subject to the provisions of Section 10.2.

Section 11.2    Removal of the General Partner. The General Partner may be removed if such removal is approved by the Unitholders holding at least 75% of the Outstanding Units (including Units held by the General Partner and its Affiliates) voting as a single class. Any such action by such holders for removal of the General Partner must also provide for the election of a successor General Partner by the Unitholders holding a majority of the outstanding Common Units voting as a class and Unitholders holding a majority of the outstanding Subordinated Units (if any Subordinated Units are then Outstanding) voting as a class (including, in each case, Units held by the General Partner and its Affiliates). Such removal shall be effective immediately following the admission of a successor General Partner pursuant to Section 10.2. The removal of the General Partner shall also automatically constitute the removal of the General Partner as general partner or managing member, to the extent applicable, of the other Group Members of which the General Partner is a general partner or a managing member. If a Person is elected as a successor General Partner in accordance with the terms of this Section 11.2, such Person shall, upon admission pursuant to Section 10.2, automatically become a successor general partner or managing member, to the extent applicable, of the other Group Members of which the General Partner is a general partner or a managing member. The right of the holders of Outstanding Units to remove the General Partner shall not exist or be exercised unless the Partnership has received an opinion opining as to the matters covered by a Withdrawal Opinion of Counsel. Any successor General Partner elected in accordance with the terms of this Section 11.2 shall be subject to the provisions of Section 10.2.

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

(a)In the event of (i) withdrawal of the General Partner under circumstances where such withdrawal does not violate this Agreement or (ii) removal of the General Partner by the holders of Outstanding Units under circumstances where Cause does not exist, if the successor

101

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

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

(b)If the Combined Interest is not purchased in the manner set forth in Section 11.3(a), the Departing General Partner (or its transferee) shall become a Limited Partner and its Combined Interest shall be converted into Common Units pursuant to a valuation made by an investment banking firm or other independent expert selected pursuant to Section 11.3(a),

102

without reduction in such Partnership Interest (but subject to proportionate dilution by reason of the admission of its successor). Any successor General Partner shall indemnify the Departing General Partner (or its transferee) as to all debts and liabilities of the Partnership arising on or after the date on which the Departing General Partner (or its transferee) becomes a Limited Partner. For purposes of this Agreement, conversion of the Combined Interest of the Departing General Partner to Common Units will be characterized as if the Departing General Partner (or its transferee) contributed its Combined Interest to the Partnership in exchange for the newly issued Common Units.

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

Section 11.4    Termination of Subordination Period, Conversion of Subordinated Units and Extinguishment of Cumulative Common Unit Arrearages. Notwithstanding any provision of this Agreement, if the General Partner is removed as general partner of the Partnership under circumstances where Cause does not exist and Units held by the General Partner and its Affiliates are not voted in favor of such removal, (i) the Subordination Period will end and all Outstanding Subordinated Units will immediately and automatically convert into Common Units on a one-for-one basis, (ii) all Cumulative Common Unit Arrearages on the Common Units will be extinguished and (iii) the General Partner will have the right to convert its General Partner Interest and its Incentive Distribution Rights into Common Units or to receive cash in exchange therefor in accordance with Section 11.3.

Section 11.5    Withdrawal of Limited Partners. No Limited Partner shall have any right to withdraw from the Partnership; provided, however, that when a transferee of a Limited Partner's Limited Partner Interest becomes a Record Holder of the Limited Partner Interest so transferred, such transferring Limited Partner shall cease to be a Limited Partner with respect to the Limited Partner Interest so transferred.

103

ARTICLE XII

DISSOLUTION AND LIQUIDATION

Section 12.1    Dissolution. The Partnership shall not be dissolved by the admission of additional Limited Partners or by the admission of a successor General Partner in accordance with the terms of this Agreement. Upon the removal or withdrawal of the General Partner, if a successor General Partner is elected pursuant to Section 11.1, Section 11.2 or Section 12.2, the Partnership shall not be dissolved and such successor General Partner shall continue the business of the Partnership. The Partnership shall dissolve, and (subject to Section 12.2) its affairs shall be wound up, upon:

(a)an Event of Withdrawal of the General Partner as provided in Section 11.1(a) (other than Section 11.1(a)(ii)), unless a successor is elected and a Withdrawal Opinion of Counsel is received as provided in Section 11.1(b) or 11.2 and such successor is admitted to the Partnership pursuant to Section 10.2;

(b)an election to dissolve the Partnership by the General Partner that is approved by the holders of a Unit Majority;

(c)the entry of a decree of judicial dissolution of the Partnership pursuant to the provisions of the Delaware Act; or

(d)at any time there are no Limited Partners, unless the Partnership is continued without dissolution in accordance with the Delaware Act.

Section 12.2    Continuation of the Business of the Partnership After Dissolution. Upon (a) dissolution of the Partnership following an Event of Withdrawal caused by the withdrawal or removal of the General Partner as provided in Section 11.1(a)(i) or (iii) and the failure of the Partners to select a successor to such Departing General Partner pursuant to Section 11.1 or Section 11.2, then, to the maximum extent permitted by law, within 90 days thereafter, or (b) dissolution of the Partnership upon an event constituting an Event of Withdrawal as defined in Section 11.1(a)(iv), (v) or (vi), then, to the maximum extent permitted by law, within 180 days thereafter, the holders of a Unit Majority may elect to continue the business of the Partnership on the same terms and conditions set forth in this Agreement by appointing as a successor General Partner a Person approved by the holders of a Unit Majority. Unless such an election is made within the applicable time period as set forth above, the Partnership shall conduct only activities necessary to wind up its affairs. If such an election is so made, then:

(i)the Partnership shall continue without dissolution unless earlier dissolved in accordance with this Article XII;

(ii)if the successor General Partner is not the former General Partner, then the interest of the former General Partner shall be treated in the manner provided in Section 11.3; and

104

(iii)the successor General Partner shall be admitted to the Partnership as General Partner, effective as of the Event of Withdrawal, by agreeing in writing to be bound by this Agreement;

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

Section 12.3     Liquidator. Upon dissolution of the Partnership in accordance with the provisions of Article XII, the General Partner shall select one or more Persons to act as Liquidator. The Liquidator (if other than the General Partner) shall be entitled to receive such compensation for its services as may be approved by holders of at least a majority of the Outstanding Common Units and Subordinated Units voting as a single class. The Liquidator (if other than the General Partner) shall agree not to resign at any time without 15 days' prior notice and may be removed at any time, with or without cause, by notice of removal approved by holders of at least a majority of the Outstanding Common Units and Subordinated Units voting as a single class. Upon dissolution, removal or resignation of the Liquidator, a successor and substitute Liquidator (who shall have and succeed to all rights, powers and duties of the original Liquidator) shall within 30 days thereafter be approved by holders of at least a majority of the Outstanding Common Units and Subordinated Units voting as a single class. The right to approve a successor or substitute Liquidator in the manner provided herein shall be deemed to refer also to any such successor or substitute Liquidator approved in the manner herein provided. Except as expressly provided in this Article XII, the Liquidator approved in the manner provided herein shall have and may exercise, without further authorization or consent of any of the parties hereto, all of the powers conferred upon the General Partner under the terms of this Agreement (but subject to all of the applicable limitations, contractual and otherwise, upon the exercise of such powers, other than the limitation on sale set forth in Section 7.3) necessary or appropriate to carry out the duties and functions of the Liquidator hereunder for and during the period of time required to complete the winding up and liquidation of the Partnership as provided for herein.

Section 12.4    Liquidation. The Liquidator shall proceed to dispose of the assets of the Partnership, discharge its liabilities, and otherwise wind up its affairs in such manner and over such period as determined by the Liquidator, subject to Section 17-804 of the Delaware Act and the following:

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

105

distribute the Partnership's assets, in whole or in part, in kind if it determines that a sale would be impractical or would cause undue loss to the Partners.

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

(c)All property and all cash in excess of that required to discharge liabilities as provided in Section 12.4(b) shall be distributed (i) first, if the IPO Closing Date has not occurred, consistently with reducing any outstanding Bronco Arrearage Amount, CERC Arrearage Amount or OGEH Arrearage Amount, as provided in Section 6.4(b), and (ii) thereafter, to the Partners in accordance with, and to the extent of, the positive balances in their respective Capital Accounts, as determined after taking into account all Capital Account adjustments (other than those made by reason of distributions pursuant to this Section 12.4(c)) for the taxable period of the Partnership during which the liquidation of the Partnership occurs (with such date of occurrence being determined pursuant to Treasury Regulation Section 1.704-1(b)(2)(ii)(g)), and such distribution shall be made by the end of such taxable period (or, if later, within 90 days after said date of such occurrence).

Section 12.5    Cancellation of Certificate of Limited Partnership. Upon the completion of the distribution of Partnership cash and property as provided in Section 12.4 in connection with the liquidation of the Partnership, the Certificate of Limited Partnership and all qualifications of the Partnership as a foreign limited partnership in jurisdictions other than the State of Delaware shall be canceled and such other actions as may be necessary to terminate the Partnership shall be taken.

Section 12.6    Return of Contributions. The General Partner shall not be personally liable for, and shall have no obligation to contribute or loan any monies or property to the Partnership to enable it to effectuate, the return of the Capital Contributions of the Limited Partners or Unitholders, or any portion thereof, it being expressly understood that any such return shall be made solely from assets of the Partnership.

Section 12.7    Waiver of Partition. To the maximum extent permitted by law, each Partner hereby waives any right to partition of the Partnership property.

Section 12.8    Capital Account Restoration. No Limited Partner shall have any obligation to restore any negative balance in its Capital Account upon liquidation of the Partnership. The General Partner shall be obligated to restore any negative balance in its Capital Account upon liquidation of its interest in the Partnership by the end of the taxable year of the Partnership during which such liquidation occurs, or, if later, within 90 days after the date of such liquidation.

(k)a merger, conveyance or conversion pursuant to Section 14.3(c); or

(l)any other amendments substantially similar to the foregoing.

Section 13.2    Amendment Procedures. Amendments to this Agreement may be proposed only by the General Partner. To the fullest extent permitted by law, the General Partner shall have no duty or obligation to propose or approve any amendment to this Agreement and may decline to do so free of any duty or obligation whatsoever to the Partnership, any Limited Partner or any other Person bound by this Agreement, and, in declining to propose or approve an amendment to this Agreement, to the fullest extent permitted by law shall not be required to act in good faith or pursuant to any other standard imposed by this Agreement, any Group Member Agreement, any other agreement contemplated hereby or under the Delaware Act or any other law, rule or regulation or at equity, and the General Partner in determining whether to propose or approve any amendment to this Agreement shall be permitted to do so in its sole and absolute discretion.

Each proposed amendment that requires the approval of the holders of a specified percentage of Outstanding Units shall be set forth in a writing that contains the text of the proposed amendment. If such an amendment is proposed, the General Partner shall seek the written approval of the requisite percentage of Outstanding Units or call a meeting of the Unitholders to consider and vote on such proposed amendment. The General Partner shall notify all Record Holders upon final adoption of any amendments. The General Partner shall be deemed to have notified all Record Holders as required by this Section 13.2 if it has posted or made accessible such amendment through the Partnership's or the Commission's website.

108

Section 13.3    Amendment Requirements.

(a)Notwithstanding the provisions of Section 13.1 and Section 13.2, no provision of this Agreement that establishes a percentage of Outstanding Units (including Units deemed owned by the General Partner) required to take any action shall be amended, altered, changed, repealed or rescinded in any respect that would have the effect of (i) in the case of any provision of this Agreement other than Section 11.2 or Section 13.4, reducing such percentage or (ii) in the case of Section 11.2 or Section 13.4, increasing such percentages, unless such amendment is approved by the written consent or the affirmative vote of holders of Outstanding Units whose aggregate Outstanding Units constitute (x) in the case of a reduction as described in subclause (a)(i) hereof, not less than the voting requirement sought to be reduced, (y) in the case of an increase in the percentage in Section 11.2, not less than 90% of the Outstanding Units, or (z) in the case of an increase in the percentage in Section 13.4, not less than a majority of the Outstanding Units.

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

(c)Except as provided in Section 14.3, and without limitation of the General Partner's authority to adopt amendments to this Agreement without the approval of any Partners as contemplated in Section 13.1, any amendment that would have a material adverse effect on the rights or preferences of any class of Partnership Interests in relation to other classes of Partnership Interests must be approved by the holders of not less than a majority of the Outstanding Partnership Interests of the class affected.

(d)Notwithstanding any other provision of this Agreement, except for amendments pursuant to Section 13.1 and except as otherwise provided by Section 14.3(b), no amendments shall become effective without the approval of the holders of at least 90% of the Outstanding Units voting as a single class unless the Partnership obtains an Opinion of Counsel to the effect that such amendment will not affect the limited liability of any Limited Partner under applicable partnership law of the state under whose laws the Partnership is organized.

(e)Except as provided in Section 13.1, this Section 13.3 shall only be amended with the approval of the holders of at least 90% of the Outstanding Units.

Section 13.4    Special Meetings. All acts of Limited Partners to be taken pursuant to this Agreement shall be taken in the manner provided in this Article XIII. Special meetings of the Limited Partners may be called by the General Partner or by Limited Partners owning 20% or more of the Outstanding Units of the class or classes for which a meeting is proposed. Limited Partners shall call a special meeting by delivering to the General Partner one or more requests in writing stating that the signing Limited Partners wish to call a special meeting and indicating the specific purposes for which the special meeting is to be called and the class or classes of Units

109

for which the meeting is proposed. No business may be brought by any Limited Partner before such special meeting except the business listed in the related request. Within 60 days after receipt of such a call from Limited Partners or within such greater time as may be reasonably necessary for the Partnership to comply with any statutes, rules, regulations, listing agreements or similar requirements governing the holding of a meeting or the solicitation of proxies for use at such a meeting, the General Partner shall send a notice of the meeting to the Limited Partners either directly or indirectly. A meeting shall be held at a time and place determined by the General Partner on a date not less than 10 days nor more than 60 days after the time notice of the meeting is given as provided in Section 16.1. Limited Partners shall not be permitted to vote on matters that would cause the Limited Partners to be deemed to be taking part in the management and control of the business and affairs of the Partnership so as to jeopardize the Limited Partners' limited liability under the Delaware Act or the law of any other state in which the Partnership is qualified to do business. If any such vote were to take place, it shall be deemed null and void to the extent necessary so as not to jeopardize the Limited Partners' limited liability under the Delaware Act or the law of any other state in which the Partnership is qualified to do business.

Section 13.5    Notice of a Meeting. Notice of a meeting called pursuant to Section 13.4 shall be given to the Record Holders of the class or classes of Units for which a meeting is proposed in writing by mail or other means of written communication in accordance with Section 16.1.

Section 13.6    Record Date. For purposes of determining the Limited Partners who are Record Holders of the class or classes of Limited Partner Interests entitled to notice of or to vote at a meeting of the Limited Partners or to give approvals without a meeting as provided in Section 13.11, the General Partner shall set a Record Date, which shall not be less than 10 nor more than 60 days before (a) the date of the meeting (unless such requirement conflicts with any rule, regulation, guideline or requirement of any National Securities Exchange on which the Units are listed or admitted to trading or U.S. federal securities laws, in which case the rule, regulation, guideline or requirement of such National Securities Exchange or U.S. federal securities laws shall govern) or (b) in the event that approvals are sought without a meeting, the date by which such Limited Partners are requested in writing by the General Partner to give such approvals.

Section 13.7    Postponement and Adjournment. Prior to the date upon which any meeting of Limited Partners is to be held, the General Partner may postpone such meeting one or more times for any reason by giving notice to each Limited Partner entitled to vote at the meeting so postponed of the place, date and hour at which such meeting would be held. Such notice shall be given not fewer than two days before the date of such meeting and otherwise in accordance with this Article XIII. When a meeting is postponed, a new Record Date need not be fixed unless the aggregate amount of such postponement shall be for more than 45 days after the original meeting date. Any meeting of Limited Partners may be adjourned by the General Partner one or more times for any reason, including the failure of a quorum to be present at the meeting with respect to any proposal or the failure of any proposal to receive sufficient votes for approval. No vote of the Limited Partners shall be required for any adjournment. A meeting of Limited Partners may be adjourned by the General Partner as to one or more proposals regardless of whether action has been taken on other matters. When a meeting is adjourned to another time or place, notice need not be given of the adjourned meeting and a new Record Date need not be

110

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

Section 13.8    Waiver of Notice; Approval of Meeting. The transactions of any meeting of Limited Partners, however called and noticed, and whenever held, shall be as valid as if it had occurred at a meeting duly held after call and notice in accordance with Sections 13.4 and 13.5, if a quorum is present either in person or by proxy. Attendance of a Limited Partner at a meeting shall constitute a waiver of notice of the meeting, except when the Limited Partner attends the meeting for the express purpose of objecting, at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened; and except that attendance at a meeting is not a waiver of any right to disapprove of any matters submitted for consideration or to object to the failure to submit for consideration any matters required to be included in the notice of the meeting, but not so included, if such objection is expressly made at the beginning of the meeting.

Section 13.9    Quorum and Voting. The presence, in person or by proxy, of holders of a majority of the Outstanding Units of the class or classes for which a meeting has been called (including Outstanding Units deemed owned by the General Partner and its Affiliates) shall constitute a quorum at a meeting of Limited Partners of such class or classes unless any such action by the Limited Partners requires approval by holders of a greater percentage of such Units, in which case the quorum shall be such greater percentage. At any meeting of the Limited Partners duly called and held in accordance with this Agreement at which a quorum is present, the act of Limited Partners holding Outstanding Units that in the aggregate represent a majority of the Outstanding Units entitled to vote at such meeting shall be deemed to constitute the act of all Limited Partners, unless a different percentage is required with respect to such action under the provisions of this Agreement, in which case the act of the Limited Partners holding Outstanding Units that in the aggregate represent at least such different percentage shall be required. The Limited Partners present at a duly called or held meeting at which a quorum is present may continue to transact business until adjournment, notwithstanding the exit of enough Limited Partners to leave less than a quorum, if any action taken (other than adjournment) is approved by the required percentage of Outstanding Units specified in this Agreement.

Section 13.10    Conduct of a Meeting. The General Partner shall have full power and authority concerning the manner of conducting any meeting of the Limited Partners or solicitation of approvals in writing, including the determination of Persons entitled to vote, the existence of a quorum, the satisfaction of the requirements of Section 13.4, the conduct of voting, the validity and effect of any proxies and the determination of any controversies, votes or challenges arising in connection with or during the meeting or voting. The General Partner shall designate a Person to serve as chairman of any meeting and shall further designate a Person to take the minutes of any meeting. All minutes shall be kept with the records of the Partnership maintained by the General Partner. The General Partner may make such other regulations consistent with applicable law and this Agreement as it may deem advisable concerning the conduct of any meeting of the Limited Partners or solicitation of approvals in writing, including regulations in regard to the appointment of proxies, the appointment and duties of inspectors of

111

votes and approvals, the submission and examination of proxies and other evidence of the right to vote, and the submission and revocation of approvals in writing.

Section 13.11    Action Without a Meeting. If authorized by the General Partner, any action that may be taken at a meeting of the Limited Partners may be taken without a meeting if an approval in writing setting forth the action so taken is signed by Limited Partners owning not less than the minimum percentage of the Outstanding Units (including Units deemed owned by the General Partner and its Affiliates) that would be necessary to authorize or take such action at a meeting at which all the Limited Partners were present and voted (unless such provision conflicts with any rule, regulation, guideline or requirement of any National Securities Exchange on which the Units are listed or admitted to trading, in which case the rule, regulation, guideline or requirement of such National Securities Exchange shall govern). Prompt notice of the taking of action without a meeting shall be given to the Limited Partners who have not approved in writing. The General Partner may specify that any written ballot submitted to Limited Partners for the purpose of taking any action without a meeting shall be returned to the Partnership within the time period, which shall be not less than 20 days, specified by the General Partner. If a ballot returned to the Partnership does not vote all of the Outstanding Units held by such Limited Partners, the Partnership shall be deemed to have failed to receive a ballot for the Outstanding Units that were not voted. If approval of the taking of any permitted action by the Limited Partners is solicited by any Person other than by or on behalf of the General Partner, the written approvals shall have no force and effect unless and until (a) approvals sufficient to take the action proposed are deposited with the Partnership in care of the General Partner, (b) approvals sufficient to take the action proposed are dated as of a date not more than 90 days prior to the date sufficient approvals are first deposited with the Partnership and (c) an Opinion of Counsel is delivered to the General Partner to the effect that the exercise of such right and the action proposed to be taken with respect to any particular matter (i) will not cause the Limited Partners to be deemed to be taking part in the management and control of the business and affairs of the Partnership so as to jeopardize the Limited Partners' limited liability, and (ii) is otherwise permissible under the state statutes then governing the rights, duties and liabilities of the Partnership and the Partners.

Section 13.12    Right to Vote and Related Matters.

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

(b)With respect to Units that are held for a Person's account by another Person that is the Record Holder (such as a broker, dealer, bank, trust company or clearing corporation, or an agent of any of the foregoing), such Record Holder shall, in exercising the voting rights in respect of such Units on any matter, and unless the arrangement between such Persons provides otherwise, vote such Units in favor of, and in accordance with the direction of, the Person who is the beneficial owner of such Units, and the Partnership shall be entitled to assume such Record

112

Holder is so acting without further inquiry. The provisions of this Section 13.12(b) (as well as all other provisions of this Agreement) are subject to the provisions of Section 4.3.

Section 13.13    Voting of Incentive Distribution Rights.

(a)For so long as a majority of the Incentive Distribution Rights are held by the General Partner and its Affiliates, the holders of the Incentive Distribution Rights shall not be entitled to vote such Incentive Distribution Rights on any Partnership matter except as may otherwise be required by law, and the holders of the Incentive Distribution Rights, in their capacity as such, shall be deemed to have approved any matter approved by the General Partner.

(b)For so long as less than a majority of the Incentive Distribution Rights are held by the General Partner and its Affiliates, the Incentive Distribution Rights will be entitled to vote on all matters submitted to a vote of Unitholders, other than amendments to this Agreement and other matters that the General Partner determines do not adversely affect the holders of the Incentive Distribution Rights as a whole in any material respect. On any matter in which the holders of Incentive Distribution Rights are entitled to vote, such holders will vote together with the Subordinated Units, prior to the end of the Subordination Period, or together with the Common Units, thereafter, in either case as a single class except as otherwise required by Section 13.3(c), and such Incentive Distribution Rights shall be treated in all respects as Subordinated Units or Common Units, as applicable, when sending notices of a meeting of Limited Partners to vote on any matter (unless otherwise required by law), calculating required votes, determining the presence of a quorum or for other similar purposes under this Agreement. The relative voting power of the Incentive Distribution Rights and the Subordinated Units or Common Units, as applicable, will be set in the same proportion as cumulative cash distributions, if any, in respect of the Incentive Distribution Rights for the four consecutive Quarters prior to the record date for the vote bears to the cumulative cash distributions in respect of such class of Units for such four Quarters.

(c)Notwithstanding Section 13.13(b), in connection with any equity financing, or

anticipated equity financing, by the Partnership of an Expansion Capital Expenditure, the General Partner may, without the approval of the holders of the Incentive Distribution Rights, temporarily or permanently reduce the amount of Incentive Distributions that would otherwise be distributed to such holders, provided that in the judgment of the General Partner, such reduction will be in the long-term best interest of the holders of the Incentive Distribution Rights.

(viii)such other provisions with respect to the proposed conversion that the General Partner determines to be necessary or appropriate.

Section 14.3    Approval by Limited Partners. Except as provided in Section 14.3(d), the General Partner, upon its approval of the Merger Agreement or the Plan of Conversion, as the case may be, shall direct that the Merger Agreement or the Plan of Conversion, as applicable, be

115

submitted to a vote of Limited Partners, whether at a special meeting or by written consent, in either case in accordance with the requirements of Article XIII. A copy or a summary of the Merger Agreement or the Plan of Conversion, as the case may be, shall be included in or enclosed with the notice of a special meeting or the written consent and, subject to any applicable requirements of Regulation 14A pursuant to the Exchange Act or successor provision, no other disclosure regarding the proposed merger, consolidation or conversion shall be required.

(a)Except as provided in Section 14.3(d), Section 14.3(e) or Section 3.4(a), the Merger Agreement or Plan of Conversion, as the case may be, shall be approved upon receiving the affirmative vote or consent of the holders of a Unit Majority unless the Merger Agreement or Plan of Conversion, as the case may be, effects an amendment to any provision of this Agreement that, if contained in an amendment to this Agreement adopted pursuant to Article XIII, would require for its approval the vote or consent of a greater percentage of the Outstanding Units or of any class of Limited Partners, in which case such greater percentage vote or consent shall be required for approval of the Merger Agreement or the Plan of Conversion, as the case may be.

(b)Except as provided in Section 14.3(d) and Section 14.3(e), after such approval by vote or consent of the Limited Partners, and at any time prior to the filing of the certificate of merger or articles of conversion pursuant to Section 14.4, the merger, consolidation or conversion may be abandoned pursuant to provisions therefor, if any, set forth in the Merger Agreement or Plan of Conversion, as the case may be.

(c)Notwithstanding anything else contained in this Article XIV or in this Agreement (other than Section 3.4(a)), the General Partner is permitted, without Limited Partner approval, to convert the Partnership or any Group Member into a new limited liability entity, to merge the Partnership or any Group Member into, or convey all of the Partnership's assets to, another limited liability entity that shall be newly formed and shall have no assets, liabilities or operations at the time of such conversion, merger or conveyance other than those it receives from the Partnership or other Group Member if (i) the General Partner has received an Opinion of Counsel that the conversion, merger or conveyance, as the case may be, would not result in the loss of limited liability under the laws of the jurisdiction governing the other limited liability entity (if that jurisdiction is not Delaware) of any Limited Partner as compared to its limited liability under the Delaware Act or cause the Partnership to be treated as an association taxable as a corporation or otherwise to be taxed as an entity for federal income tax purposes (to the extent not previously treated as such), (ii) the sole purpose of such conversion, merger, or conveyance is to effect a mere change in the legal form of the Partnership into another limited liability entity and (iii) the General Partner determines that the governing instruments of the new entity provide the Limited Partners and the General Partner with substantially the same rights and obligations as are herein contained.

(d)Additionally, notwithstanding anything else contained in this Article XIV or in this Agreement (other than Section 3.4(a)), the General Partner is permitted, without Limited Partner approval, to merge or consolidate the Partnership with or into another limited liability entity if (i) the General Partner has received an Opinion of Counsel that the merger or consolidation, as the case may be, would not result in the loss of the limited liability of any Limited Partner under the laws of the jurisdiction governing the other limited liability entity (if

116

that jurisdiction is not Delaware) as compared to its limited liability under the Delaware Act or cause the Partnership to be treated as an association taxable as a corporation or otherwise to be taxed as an entity for federal income tax purposes (to the extent not previously treated as such), (ii) the merger or consolidation would not result in an amendment to this Agreement, other than any amendments that could be adopted pursuant to Section 13.1, (iii) the Partnership is the Surviving Business Entity in such merger or consolidation, (iv) each Unit outstanding immediately prior to the effective date of the merger or consolidation is to be an identical Unit of the Partnership after the effective date of the merger or consolidation, and (v) the number of Partnership Interests to be issued by the Partnership in such merger or consolidation does not exceed 20% of the Partnership Interests (other than Incentive Distribution Rights) Outstanding immediately prior to the effective date of such merger or consolidation.

(e)Pursuant to Section 17-211(g) of the Delaware Act, an agreement of merger or consolidation approved in accordance with this Article XIV may (i) effect any amendment to this Agreement or (ii) effect the adoption of a new partnership agreement for the Partnership if it is the Surviving Business Entity. Any such amendment or adoption made pursuant to this Section 14.3 shall be effective at the effective time or date of the merger or consolidation.

Section 14.4    Certificate of Merger or Certificate of Conversion. Upon the required approval by the General Partner and the Unitholders of a Merger Agreement or the Plan of Conversion, as the case may be, a certificate of merger or certificate of conversion or other filing, as applicable, shall be executed and filed with the Secretary of State of the State of Delaware or the appropriate filing office of any other jurisdiction, as applicable, in conformity with the requirements of the Delaware Act or other applicable law.

Section 14.5    Effect of Merger, Consolidation or Conversion.

(a)At the effective time of the merger:

(i)all of the rights, privileges and powers of each of the business entities that has merged or consolidated, and all property, real, personal and mixed, and all debts due to any of those business entities and all other things and causes of action belonging to each of those business entities, shall be vested in the Surviving Business Entity and after the merger or consolidation shall be the property of the Surviving Business Entity to the extent they were of each constituent business entity;

(ii)the title to any real property vested by deed or otherwise in any of those constituent business entities shall not revert and is not in any way impaired because of the merger or consolidation;

(iii)all rights of creditors and all liens on or security interests in property of any of those constituent business entities shall be preserved unimpaired; and

(iv)all debts, liabilities and duties of those constituent business entities shall attach to the Surviving Business Entity and may be enforced against it to the same extent as if the debts, liabilities and duties had been incurred or contracted by it.

(b)At the effective time of the conversion:

117

(i)the Partnership shall continue to exist, without interruption, but in the organizational form of the converted entity rather than in its prior organizational form;

(ii)all rights, title, and interests to all real estate and other property owned by the Partnership shall continue to be owned by the converted entity in its new organizational form without reversion or impairment, without further act or deed, and without any transfer or assignment having occurred, but subject to any existing liens or other encumbrances thereon;

(iii)all liabilities and obligations of the Partnership shall continue to be liabilities and obligations of the converted entity in its new organizational form without impairment or diminution by reason of the conversion;

(iv)all rights of creditors or other parties with respect to or against the prior interest holders or other owners of the Partnership in their capacities as such in existence as of the effective time of the conversion will continue in existence as to those liabilities and obligations and may be pursued by such creditors and obligees as if the conversion did not occur;

(v)a proceeding pending by or against the Partnership or by or against any of Partners in their capacities as such may be continued by or against the converted entity in its new organizational form and by or against the prior partners without any need for substitution of parties; and

(vi)the Partnership Interests that are to be converted into partnership interests, shares, evidences of ownership, or other securities in the converted entity as provided in the plan of conversion shall be so converted, and Partners shall be entitled only to the rights provided in the Plan of Conversion.

ARTICLE XV

RIGHT TO ACQUIRE LIMITED PARTNER INTERESTS

Section 15.1    Right to Acquire Limited Partner Interests.

(a)Notwithstanding any other provision of this Agreement, if at any time after the consummation of the Initial Public Offering, the General Partner and its Affiliates hold more than 80% of the total Limited Partner Interests of any class then Outstanding, the General Partner shall then have the right, which right it may assign and transfer in whole or in part to the Partnership or any Affiliate of the General Partner, exercisable at its option, to purchase all, but not less than all, of such Limited Partner Interests of such class then Outstanding held by Persons other than the General Partner and its Affiliates, at the greater of (x) the Current Market Price as of the date three Business Days prior to the date that the notice described in Section 15.1(b) is mailed and (y) the highest price paid by the General Partner or any of its Affiliates for any such Limited Partner Interest of such class purchased during the 90-day period preceding the date that the notice described in Section 15.1(b) is mailed.

118

(b)If the General Partner any Affiliate of the General Partner or the Partnership elects to exercise the right to purchase Limited Partner Interests granted pursuant to Section 15.1(a), the General Partner shall deliver to the applicable Transfer Agent notice of such election to purchase (the “Notice of Election to Purchase”) and shall cause the Transfer Agent to mail a copy of such Notice of Election to Purchase to the Record Holders of Limited Partner Interests of such class (as of a Record Date selected by the General Partner), together with such information as may be required by law, rule or regulation, at least 10, but not more than 60, days prior to the Purchase Date. Such Notice of Election to Purchase shall also be filed and distributed as may be required by the Commission or any National Securities Exchange on which such Limited Partner Interests are listed. The Notice of Election to Purchase shall specify the Purchase Date and the price (determined in accordance with Section 15.1(a)) at which Limited Partner Interests will be purchased and state that the General Partner, its Affiliate or the Partnership, as the case may be, elects to purchase such Limited Partner Interests, upon surrender of Certificates representing such Limited Partner Interests, in the case of Limited Partner Interests evidenced by Certificates, or instructions agreeing to such redemption in exchange for payment, at such office or offices of the Transfer Agent as the Transfer Agent may specify, or as may be required by any National Securities Exchange on which such Limited Partner Interests are listed. Any such Notice of Election to Purchase mailed to a Record Holder of Limited Partner Interests at his address as reflected in the Register shall be conclusively presumed to have been given regardless of whether the owner receives such notice. On or prior to the Purchase Date, the General Partner, its Affiliate or the Partnership, as the case may be, shall deposit with the Transfer Agent or exchange agent cash in an amount sufficient to pay the aggregate purchase price of all of such Limited Partner Interests to be purchased in accordance with this Section 15.1. If the Notice of Election to Purchase shall have been duly given as aforesaid at least 10 days prior to the Purchase Date, and if on or prior to the Purchase Date the deposit described in the preceding sentence has been made for the benefit of the holders of Limited Partner Interests subject to purchase as provided herein, then from and after the Purchase Date, notwithstanding that any Certificate or redemption instructions shall not have been surrendered for purchase or provided, respectively, all rights of the holders of such Limited Partner Interests (including any rights pursuant to Article IV, Article V, Article VI, and Article XII) shall thereupon cease, except the right to receive the purchase price (determined in accordance with Section 15.1(a)) for Limited Partner Interests therefor, without interest, upon surrender to the Transfer Agent of the Certificates representing such Limited Partner Interests, in the case of Limited Partner Interests evidenced by Certificates, or instructions agreeing to such redemption, and such Limited Partner Interests shall thereupon be deemed to be transferred to the General Partner, its Affiliate or the Partnership, as the case may be, in the Register, and the General Partner or any Affiliate of the General Partner, or the Partnership, as the case may be, shall be deemed to be the Record Holder of all such Limited Partner Interests from and after the Purchase Date and shall have all rights as the Record Holder of such Limited Partner Interests (including all rights as owner of such Limited Partner Interests pursuant to Article IV, Article V, Article VI and Article XII).

(c)In the case of Limited Partner Interests evidenced by Certificates, at any time from and after the Purchase Date, a holder of an Outstanding Limited Partner Interest subject to purchase as provided in this Section 15.1 may surrender his Certificate evidencing such Limited Partner Interest to the Transfer Agent in exchange for payment of the amount described in

119

Section 15.1(a), therefor, without interest thereon, in accordance with procedures set forth by the General Partner.

Any notice to the Partnership shall be deemed given if received by the General Partner at the principal office of the Partnership designated pursuant to Section 2.3.

EXHIBIT D

Partnership Equity Value Example

For example, assuming the aggregate amount of Adjusted Available Cash for four most recently completed Quarters is $575,250,300, the Alerian MLP Index Yield is 5.00% for the period of determination and the number of Common Units Outstanding are 506,986,500, the Partnership Equity Value and Unit Price would be derived as follows:

Partnership Equity Value	=	Aggregate Adjusted Available Cash for four recent Quarters
		5.8% * [(Current Alerian MLP Yield)/5.97%)]

Therefore, for example:

= $575,250,300 / [5.8% * (5.00%/(5.97%))]

= $ 11,842,221,693

Unit Price =Partnership Equity Value/Common Units Outstanding

Therefore, for example: = $ 11,842,221,693 / 506,986,500 units

= $23.35 / unit

RIGHTS UPON A PROPOSED TRANSFER

Section 5.01Right of First Offer.

(a)Following the Control Period, except for a Permitted Transfer, no Membership Interest shall be Transferred unless the provisions of this Section 5.01 or Section 5.02 are first complied with. If a Member (the “ROFO Seller”) wishes to solicit proposals from third parties to acquire all, but not less than all, of the ROFO Seller's Units, the ROFO Seller shall first provide a notice (the “ROFO Notice”) to the other Member, with a copy to the Company,

19

containing: (i) the number and class of Units proposed to be transferred (the “ROFO Units”) and (ii) a request for the other Member (the “ROFO Non-Selling Member”) to specify the purchase price (the “ROFO Price”) and other terms and conditions on which the ROFO Non-Selling Member is willing to purchase the ROFO Units.

(b)Within 30 days after receiving the ROFO Notice, the ROFO Non-Selling Member (the “ROFO Accepting Member”) may elect (the “ROFO Offer Notice”) to purchase all, but not less than all, of the ROFO Units. The ROFO Offer Notice shall specify the ROFO Price and other terms and conditions on which the ROFO Accepting Member is willing to purchase the ROFO Units. If the ROFO Accepting Member submits a ROFO Offer Notice within the time period specified herein, the ROFO Seller shall have 30 days from the date it received the ROFO Offer Notice to elect (the “ROFO Acceptance Notice”) to accept the ROFO Accepting Member's offer to purchase the ROFO Units.

(c)If the ROFO Seller accepts the ROFO Accepting Member's offer, the ROFO Accepting Member must purchase the ROFO Units in the manner, and subject to the terms and conditions, described in Section 5.01(d). If the ROFO Seller does not accept the offer from the ROFO Accepting Member or fails to make such election within 30 days after receiving the ROFO Offer Notice, the ROFO Seller may, during the next 120 days, Transfer the ROFO Units to a third party Transferee (i) at a purchase price not less than 105% of the ROFO Price and upon terms no more favorable to the proposed transferee than those specified in the ROFO Notice and (ii) subject to the applicable terms and restrictions of this Agreement, including Article IV.

(d)Sales of the ROFO Units to the ROFO Accepting Member pursuant to this Section 5.01 shall be made at the offices of the Company within 60 days of the delivery of ROFO Acceptance Notice, or on such other date as the parties may agree.

Delivery of the ROFR Sellers's Notice to the other Member (the “ROFR Non-Transferring Member”) shall constitute an offer (a “ROFR Offer”) by the ROFR Seller to sell the ROFR Units at the ROFR Sale Price to the ROFR Non-Transferring Member, which shall remain outstanding for a period of thirty (30) days after the delivery of the ROFR Seller's Notice (subject to extension as provided below, the “ROFR Period”).

(c)A failure by the ROFR Non-Transferring Member to validly deliver a ROFR Acceptance Notice during the ROFR Period shall be deemed a rejection of the ROFR Offer and a waiver of the ROFR Non-Transferring Member's right to purchase any portion of the ROFR Units.

(d)If the ROFR Non-Transferring Member does not elect to purchase all of the ROFR Units pursuant to this Section 5.02, then the ROFR Seller shall be free, for a period of sixty (60) days from the date of the expiration of the ROFR Period, to sell such ROFR Units to a third party (the “Proposed Transferee”) (x) at a price per Unit equal to or greater than the ROFR Price and upon terms no more favorable to the Proposed Transferee than those specified in the ROFR Seller's Notice and (y) subject to the applicable terms and restrictions of this Agreement, including Article IV.

The borrowing party shall reimburse the lending party for any costs (other than any additional interest costs) incurred by the lending party in connection with the borrowing of such funds. For purposes of this Section 7.03(a) and Section 7.03(b), the term “Group Member” shall include any Affiliate of a Group Member that is controlled by the Group Member.

(b)No Group Member may lend funds to the Company or any of its Affiliates (other than another Group Member).

(c)Any Member may, subject to Section 9.04, loan funds to the Company. Loans by a Member to the Company will not be treated as Capital Contributions but will be treated as debt obligations having such terms as are approved in accordance with Section 9.04.

Section 7.04Return of Contributions.

Except as expressly provided herein, no Economic Member is entitled to the return of any part of its Capital Contributions or to be paid interest in respect of either its Capital Account or its Capital Contributions. An unrepaid Capital Contribution is not a liability of the Company or of any Economic Member. An Economic Member is not required to contribute or to lend any cash or property to the Company to enable the Company to return any Economic Member's Capital Contributions.

22

Section 7.05Capital Accounts.

A separate capital account (“Capital Account”) shall be established, determined and maintained for each Economic Member in accordance with the substantial economic effect test set forth in Treasury Regulation § 1.704-l(b)(2), which provides, in part, that a Capital Account shall be:

(a)increased by (i) the amount of money contributed by the Economic Member to the Company; (ii) the fair market value of any property contributed by the Economic Member to the Company (net of liabilities secured by such contributed property); and (iii) allocations to the Economic Member of the Company income and gain (or items thereof), including income and gain exempt from tax; and

(b)decreased by (i) the amount of money distributed to the Economic Member by the Company; (ii) the fair market value of any property distributed to the Economic Member by the Company (net of liabilities secured by such distributed property); (iii) allocations to the Economic Member of expenditures of the Company not deductible in computing its taxable income and not properly capitalized for federal income tax purposes; and (iv) allocations to the Economic Member of Company loss and deduction (or items thereof).

In the case of a termination of a an Economic Unit or an additional Capital Contribution by an existing or newly admitted Economic Member, the Capital Accounts of the Economic Members shall be adjusted as of the date of such termination or the date of the Capital Contribution, as the case may be.

ARTICLE VIII.

DISTRIBUTIONS AND ALLOCATIONS

Section 8.01Distributions.

(a)Except as otherwise provided in Section 16.03, within fifty (50) days following the end of each Quarter commencing with the Quarter ending on June 30, 2013, an amount equal to 100% of Available Cash with respect to such Quarter shall be distributed in accordance with this Article VIII to all Economic Members simultaneously pro rata in accordance with each Economic Member's Ownership Percentage (at the time the amounts of such distributions are determined).

(b)Each distribution in respect of an Economic Unit shall be paid by the Company only to the holder of record of such Economic Unit as of the record date set for such distribution. Such payment shall constitute full payment and satisfaction of the Company's liability in respect of such payment, regardless of any claim of any Person who may have an interest in such payment by reason of an assignment or otherwise.

Section 8.02Allocations.

After giving effect to the allocations set forth in Section 8.03, the Company shall allocate Profits and Losses for any Allocation Year among the Economic Members in accordance with the Economic Members' Ownership Percentages.

23

Section 8.03Special Allocations.

(a)If there is a net decrease in Company Minimum Gain during any Allocation Year, each Economic Member shall be allocated items of Company income and gain for such Allocation Year (and, if necessary, subsequent Allocation Years) in the manner and amounts provided in Treasury Regulation Sections 1.704-2(f)(6), 1.704-2(g)(2) and 1.704-2(j)(2)(i), or any successor provision. This Section 8.03(a) is intended to comply with the Company Minimum Gain chargeback requirement in Treasury Regulation Section 1.704-2(f) and shall be interpreted consistently therewith.

(b)Except as provided in Treasury Regulation Section 1.704-2(i)(4), if there is a net decrease in Member Nonrecourse Debt Minimum Gain during any Allocation Year, any Economic Member with a share of Member Nonrecourse Debt Minimum Gain at the beginning of such Allocation Year shall be allocated items of Company income and gain for such Allocation Year (and, if necessary, subsequent Allocation Years) in the manner and amounts provided in Treasury Regulation Sections 1.704-2(i)(4) and 1.704-2(j)(2)(ii), or any successor provisions. This Section 8.03(b) is intended to comply with the chargeback of items of income and gain requirement in Treasury Regulation Section 1.704-2(i)(4) and shall be interpreted consistently therewith.

(c)In the event any Economic Member has a deficit balance in its Capital Account at the end of any Allocation Year in excess of the sum of (A) the amount such Economic Member is required to restore pursuant to the provisions of this Agreement and (B) the amount such Economic Member is deemed obligated to restore pursuant to Treasury Regulation Sections 1.704-2(g) and 1.704-2(i)(5), such Economic Member shall be specially allocated items of Company gross income and gain in the amount of such excess as quickly as possible; provided, that an allocation pursuant to this Section 8.03(c) shall be made only if and to the extent that such Economic Member would have an Adjusted Capital Account Deficit after all other allocations provided for in this Article VIII have been tentatively made as if this Section 8.03(c) were not in this Agreement.

(d)In the event any Economic Member has a deficit balance in its Capital Account at the end of any Allocation Year in excess of the sum of (A) the amount such Economic Member is required to restore pursuant to the provisions of this Agreement and (B) the amount such Economic Member is deemed obligated to restore pursuant to Treasury Regulation Sections 1.704-2(g) and 1.704-2(i)(5), such Economic Member shall be specially allocated items of Company gross income and gain in the amount of such excess as quickly as possible; provided, that an allocation pursuant to this Section 8.03(d) shall be made only if and to the extent that such Economic Member would have an Adjusted Capital Account Deficit after all other allocations provided for in this Article VIII have been tentatively made as if Section 8.03(c) and this Section 8.03(d) were not in this Agreement.

(e)Nonrecourse Deductions for any Allocation Year shall be allocated to the Economic Members pro rata in accordance with each Economic Member's Ownership Percentage.

24

(f)Member Nonrecourse Deductions for any Allocation Year shall be allocated 100% to the Economic Member that bears the economic risk of loss with respect to the Member Nonrecourse Debt to which such Member Nonrecourse Deductions are attributable in accordance with Treasury Regulation Section 1.704-2(i). If more than one Economic Member bears the economic risk of loss with respect to a Member Nonrecourse Debt, such Economic Member Nonrecourse Deductions attributable thereto shall be allocated between or among such Economic Members in accordance with the ratios in which they share such economic risk of loss.

(g)For purposes of Treasury Regulation Section 1.752-3(a)(3), the Economic Members agree that Nonrecourse Liabilities of the Company shall be allocated to the Economic Members pro rata in accordance with each Economic Member's Ownership Percentage.

(h)To the extent an adjustment to the adjusted tax basis of any Company asset pursuant to Section 734(b) or 743(b) of the Code is required, pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts, the amount of such adjustment to the Capital Accounts shall be treated as an item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment decreases such basis), and such item of gain or loss shall be specially allocated to the Economic Members in a manner consistent with the manner in which their Capital Accounts are required to be adjusted pursuant to such Section of the Treasury Regulations.

(i)Notwithstanding any other provision of this Section 8.03, the allocations set forth in Sections 8.03(a), (b), (c), (d), (e), (f) and (h) (the “Required Allocations”) shall be taken into account so that, to the extent possible, the net amount of items of gross income, gain, loss and deduction allocated to each Economic Member pursuant to Sections 8.02 and 8.03, together, shall be equal to the net amount of such items that would have been allocated to each such Economic Member under Section 8.02 and Section 8.03 had the Required Allocations and this Section 8.03(i) not otherwise been provided in this Agreement. The Company may take into account future Required Allocations that, although not yet made, are likely to offset other Required Allocations previously made.

(j)Items of income, gain, loss and deduction realized in any taxable year that includes a Dissolution Event shall be allocated in a manner that will cause, to the extent possible, the ratio of each Economic Member's Capital Account to the sum of all Economic Members' Capital Accounts to be equal to such Economic Member's Ownership Percentage. Upon a Dissolution Event, if any property is distributed in kind, any unrealized income, gain, loss, and deduction inherent in property that has not been reflected in the Capital Accounts previously shall be allocated among the Economic Members as if there were a taxable disposition of that property for the fair market value of that property on the date of distribution.

(k)The allocations in Section 8.02, this Section 8.03 and Section 8.05, and the provisions of this Agreement relating to the maintenance of Capital Accounts, are included to ensure compliance with requirements of the federal income tax law (and any applicable state income tax laws). Such provisions are intended to comply with Treasury Regulations Sections 1.704-1 and 1.704-2 and shall be interpreted and applied in a manner consistent with such Treasury Regulations and any amendment or successor provision thereto. The Management Members shall cause appropriate modifications to be made if unanticipated events might

25

otherwise cause this Agreement not to comply with such Treasury Regulations, so long as such modifications do not cause a material change in the relative economic benefit of the Economic Members under this Agreement.

Section 8.04Section 704(c).

In accordance with Section 704(c) of the Code and the Treasury Regulations thereunder, income, gain, loss, and deduction with respect to any property contributed to the capital of the Company shall, solely for tax purposes, be allocated among the Economic Members to take account of any variation between the adjusted basis of such property to the Company for federal income tax purposes and its initial Gross Asset Value (computed in accordance with the definition of same under this Agreement). In the event the Gross Asset Value of any Company asset is adjusted pursuant to subparagraph (b) of the definition of Gross Asset Value hereof, subsequent allocations of income, gain, loss, and deduction with respect to such asset shall take account of any variation between the adjusted basis of such asset for federal income tax purposes and its Gross Asset Value in the same manner as under Section 704(c) of the Code and the Treasury Regulations thereunder. Any elections or other decisions relating to such allocations shall be made by the Board in any manner that reasonably reflects the purpose and intention of this Agreement; provided that the Company shall use the traditional method without curatives set forth in Treasury Regulation Section 1.704-3(b). Allocations pursuant to this Section 8.04 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 Economic Member's Capital Account or share of Profits, Losses, other items, or distributions pursuant to any provision of this Agreement.

Section 8.05Varying Interests.

All items of income, gain, loss, deduction or credit shall be allocated, and all distributions shall be made, to the Persons shown on the records of the Company to have been Economic Members as of the last calendar day of the period for which the allocation or distribution is to be made. Notwithstanding the foregoing, if during any taxable year there is a change in any Economic Member's Ownership Percentage, the Economic Members agree that their allocable shares of such items for the taxable year shall be determined on any method determined by the Board to be permissible under Code Section 706 and the related Treasury Regulations to take account of the Economic Members' varying Ownership Percentages.

Section 8.06Withheld Taxes.

All amounts withheld pursuant to the Code or any provision of any state or local tax law with respect to any payment, distribution or allocation to the Company or the Economic Members shall be treated as amounts distributed to the Economic Members pursuant to this Article VIII for all purposes of this Agreement. The Company is authorized to withhold from distributions, or with respect to allocations, to the Economic Members and to pay over to any federal, state or local government any amounts required to be so withheld pursuant to the Code or any provision of any other federal, state or local law and shall allocate such amounts to those Economic Members with respect to which such amounts were withheld.

Section 8.07Limitations on Distributions.

26

Notwithstanding any provision to the contrary contained in this Agreement, the Company shall not make a distribution to any Member on account of its interest in the Company if such distribution would violate Section 18-607 of the Delaware Act or other applicable law. All distributions required to be made under this Agreement shall be made subject to Sections 18-607 and 18-804 of the Delaware Act.

ARTICLE IX.

If any other Director shall cease to serve as a Director for any reason, the vacancy resulting thereby will be filled by another Director designated in accordance with Section 9.02(b)(ii).

Special meetings of the Board, to be held at the offices of the Company (or such other place as shall be determined by the Board), shall be called at the direction of any one Director. Attendance of a Director at a meeting shall constitute a waiver of notice of such meeting, except where a Director attends a meeting for the express purpose of objecting to the transaction of any business on the ground that such meeting is not properly called or convened.

Within five days after receipt of the Deadlock Notice, the receiving Management Member shall submit to the other Management Member a written response (a “Dispute Response”). The Dispute Notice and the Dispute Response shall each include (A) a statement setting forth the position of the Management Member giving the notice and a summary of arguments supporting such position and (B) the name and title of a senior representative of such Management Member who has authority to settle the Deadlock. Within five days of the delivery of the Dispute Response, the senior representatives of both Management Members shall meet or communicate by telephone at a mutually acceptable time and place, and thereafter as often as they reasonably deem necessary, and shall negotiate in good faith to the resolve the Deadlock.

both Members who have authority to settle the Deadlock in attendance, or (B) on or after the IPO Date, such Deadlock shall be resolved by the affirmative vote of a majority of the Independent Directors on the Board.

(iv)Notwithstanding anything herein to the contrary, until a Deadlock is resolved, each Management Member agrees to continue to perform its obligations under this Agreement and to cause its Representatives to continue to perform their obligations under this Agreement. In the event a Deadlock exists with respect to any Annual Budget, then, until such time as such Deadlock is resolved, the Annual Budget for such calendar year shall be based on the corresponding portions of the Annual Budget for the preceding calendar year (excluding any unusual or extraordinary revenues, expenses or capital expenditures that occurred during such prior calendar year), together with any additional amounts to the extent necessary, when combined with amounts authorized to be spent in such last Annual Budget, to meet the Partnership's existing commitments and obligations and to conduct and maintain the Partnership's operations and properties in the ordinary course of business. With respect to non-recurring amounts and capital expenditures, if any, for which there is no corresponding portion of the Annual Budget for the preceding calendar year, only budgeted amounts directed or approved by the Board of Directors on a case by case basis shall be utilized.

(d)Related Party Transactions. After the IPO Date, any Related Party Transactions shall be approved in accordance with the applicable provisions of the Partnership Agreement.

Section 9.05Notice.

Written notice of all regular meetings of the Board shall be given to all Directors and Alternate Directors at least 10 days prior to the regular meeting of the Board and one Business Day prior to any special meeting of the Board.

A meeting may be held at any time without notice if all the Directors are present or if those not present waive notice of the meeting either before or after such meeting. Notwithstanding anything in the foregoing to the contrary, the failure to give notice or documents or other information to an Alternate Director that is acting solely in an observer capacity shall not affect the validity of any action taken by the Board.

Section 9.06Action by Written Consent of Board.

To the extent permitted by applicable law, the Board may act without a meeting, without notice and without a vote, if a consent or consents in writing, setting forth the action so taken, shall be signed by all Directors (which, for the avoidance of doubt, need not include the consent of any Alternate Directors unless a particular Alternate Director is serving in place of a

32

Management Member's designated Director). All actions taken by the Board in the form of a written consent shall be distributed to each Director and Alternate Director promptly upon the taking of such action.

Section 9.07Conference Telephone Meetings.

Directors and Alternate Directors may participate in a meeting of the Board or any committee thereof by means of conference telephone or similar communications equipment by means of which all persons participating in the meeting can hear each other, and such participation in a meeting shall constitute presence in person at such meeting.

All decisions and resolutions of the Board shall be reported in the minutes of its meetings, which shall state the date, time and place of the meeting (or the date of the written consent in lieu of a meeting), the persons present at the meeting, the resolutions put to a vote (or the subject of a written consent) and the results of such voting (or written consent).

38

defending any claim, demand, action, suit or proceeding shall, from time to time, be advanced by the Company prior to a final and non-appealable judgment entered by a court of competent jurisdiction determining that, in respect of the matter for which the Indemnitee is seeking indemnification pursuant to this Section 13.01, the Indemnitee is not entitled to be indemnified upon receipt by the Company of any undertaking by or on behalf of the Indemnitee to repay such amount if it shall be ultimately determined that the Indemnitee is not entitled to be indemnified as authorized by this Section 13.01.

(c)The indemnification provided by this Section 13.01 shall be in addition to any other rights to which an Indemnitee may be entitled under any agreement, pursuant to any vote of a Majority Interest or of the Board, as a matter of law, in equity or otherwise, both as to actions in the Indemnitee's capacity as an Indemnitee and as to actions in any other capacity, and shall continue as to an Indemnitee who has ceased to serve in such capacity and shall inure to the benefit of the heirs, successors, assigns and administrators of the Indemnitee.

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

(e)For purposes of this Section 13.01, the Company shall be deemed to have requested an Indemnitee to serve as fiduciary of an employee benefit plan whenever the performance by it of its duties to the Company also imposes duties on, or otherwise involves services by, it to the plan or participants or beneficiaries of the plan; excise taxes assessed on an Indemnitee with respect to an employee benefit plan pursuant to applicable law shall constitute “fines” within the meaning of Section 13.01(a); and action taken or omitted by it with respect to any employee benefit plan in the performance of its duties for a purpose reasonably believed by it to be in the best interest of the participants and beneficiaries of the plan shall be deemed to be for a purpose that is in the best interests of the Company.

39

of any past, present or future Indemnitee to be indemnified by the Company, nor the obligations of the Company to indemnify any such Indemnitee under and in accordance with the provisions of this Section 13.01 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted.

(ii)Subject to Section 2(c)(ii), (A) the Holders shall be permitted to include for registration in the IPO Registration Statement, on the same terms and conditions as the primary Common Units proposed to be offered and sold for the account of the Partnership, the number of Registrable Securities as they may request and (B) if the Initial Public Offering contemplates an “over-allotment option,” Bronco shall be permitted to include in such over-allotment option a number of Registrable Securities held by Bronco up to 100% of the securities subject to such over-allotment option.

6

Initial Public Offering (including registering the Common Units under the Exchange Act and causing the Common Units to be listed on the Trading Market) as promptly as reasonably practicable, but (except in the case of a Delaying Event as set forth in Section 2(a)(iv)) not later than 180 days following the Filing Date.

To exercise an extension due to a Delaying Event, the General Partner shall provide to Bronco a certificate executed by a senior executive officer of the General Partner stating that the Board of Directors has determined in good faith that a Delaying Event has occurred. Once the Delaying Event no longer exists, the Partnership shall use reasonable best efforts to promptly cause the IPO Registration Statement to become effective. During the extended period caused by the Delaying Event, the Partnership shall use reasonable best efforts to continue to update the IPO Registration Statement and work with the Commission so that the IPO Registration Statement can be declared effective promptly upon the expiration of the extended period.

(b)Demand Registration Rights.

(i)Demand Registrations of Sponsor Party Holders. At any time following the date that is 180 days after the IPO Date, any Sponsor Party Holder that holds Registrable Securities (the “Sponsor Party Initiating Holder”) shall have the option and right, exercisable by delivering a written notice to the Partnership (a “Sponsor Party Demand Notice”), to require the Partnership to, pursuant to the terms of and subject to the limitations contained in this Agreement, prepare and file with the Commission a Registration Statement registering the offering and sale of all or any portion of such Sponsor Party Holder's Registrable Securities, which may, at the option of the Initiating Holder, be a Shelf Registration Statement (the “Sponsor Party Demand Registration”).

(ii)Demand Registrations of Bronco. At any time following the date that the Partnership is first eligible to file a registration statement under Form S-3 (or any equivalent or successor form under the Securities Act), Bronco, for as long as it holds Registrable Securities (together with any Sponsor Party Initiating Holder, an “Initiating Holder”), shall have the option and right, exercisable by delivering a written notice to the Partnership (together with a Sponsor Party Demand Notice, a “Demand Notice”), to require the Partnership to, pursuant to the terms of and subject to the limitations contained in this Agreement, prepare and file with the Commission a Registration Statement registering the offering and sale of all or any portion of Bronco's Registrable Securities, which may, at the option of Bronco, be a Shelf Registration Statement (an “Bronco Demand Registration” and, together with a Sponsor Party Demand Registration, a “Demand Registration”).

(iii)Within ten Business Days of the receipt of the Demand Notice, the Partnership shall give written notice of such Demand Notice to all other Holders that hold the same class of securities as the Registrable Securities and shall, subject to the limitations of this

7

Section 2(b), use reasonable best efforts to file a Registration Statement covering all of the Registrable Securities that such Holders shall in writing request (such request to be given to the Partnership within ten Business Days of written receipt of such notice of the Demand Notice given by the Partnership pursuant to this Section 2(b)(iii)) to be included in such Demand Registration as promptly as reasonably practicable as directed by the Initiating Holder in accordance with the terms and conditions of the Demand Notice and use reasonable best efforts to cause such Registration Statement to become effective under the Securities Act and remain effective under the Securities Act for not less than six months following the Effective Date or such longer period ending when all Registrable Securities covered by such Registration Statement have been sold (the “Effectiveness Period”).

(iv)Subject to the other limitations contained in this Agreement, the Partnership shall not be obligated hereunder to effect more than (A) one Demand Registration pursuant to Section 2(b)(ii) in any 12-month period, (B) three Demand Registrations on Form S-3 (or any equivalent or successor form under the Securities Act) pursuant to Section 2(b)(i) or (C) two Demand Registrations on Form S-3 (or any equivalent or successor form under the Securities Act) pursuant to Section 2(b)(ii).

(v)Notwithstanding any other provision of this Section 2(b), the Partnership shall not be required to effect a registration or file a Registration Statement pursuant to this Section 2(b): (A) during the period starting with notice to the Holder of the intent to file a Registration Statement under Sections 2(b)(iii) or 2(c)(i) (which shall occur no earlier than 60 days prior to a good faith estimate, with the approval of the Board of Directors, of the date of filing of such Registration Statement) and ending on a date 90 days after the effective date of, a Partnership-initiated registration; provided that the Partnership uses reasonable best efforts to cause such registration statement to become effective; (B) for a period of up to 90 days after the date of a Demand Notice for registration pursuant to this Section 2(b) if at the time of such request the Partnership is currently engaged in a self-tender or exchange offer and the filing of a Registration Statement would cause a violation of the Exchange Act; or (C) for a period of up to 90 days, if the Conflicts Committee, proceeding in good faith, determines that the filing of a Registration Statement would require an Adverse Disclosure; provided, that, in such event, the Holders requesting such Demand Registration may withdraw such request and, if withdrawn, such request will not count as one of the permitted Demand Registrations hereunder and the Partnership will pay all expenses (including reasonable attorneys fees) in connection with such registrations; provided, further, that the Partnership may delay a Demand Registration hereunder only once in any 12 month period.

(vi)Notwithstanding any other provision of this Section 2(b), if (A) the Holders intend to distribute the Registrable Securities covered by a Demand Registration by means of an underwritten public offering and (B) the managing underwriter or managing underwriters of such offering advise the Partnership in writing that, in their opinion, the inclusion of all of such Holders' Registrable Securities in the subject Registration Statement would have a material adverse

8

effect on the marketability of the offering, then the Partnership shall so advise all Holders of such Registrable Securities that would otherwise be underwritten pursuant hereto, and the number of Registrable Securities that may be included in the underwriting shall be reduced to equal the number of Registrable Securities that such managing underwriter or managing underwriters advise the Partnership can be sold without having such material adverse effect. The aggregate number of Registrable Securities to be included in such Demand Registration as a result of the reduction described in the immediately preceding sentence shall be (A) in the case of a Sponsor Party Demand Registration, reduced pro rata among the Holders seeking to include their Registrable Securities in the underwriting, based, for each such Holder, on the percentage derived by dividing (x) the number of Registrable Securities owned by such Holder by (y) the total number of Registrable Securities owned by all the Holders seeking to include their Registrable Securities in the underwriting, or (B) in the case of a Bronco Demand Registration, allocated first to Bronco based on the number of Registrable Securities proposed to be sold by Bronco. If there remains availability for additional Registrable Securities to be included in such Bronco Demand Registration, the aggregate number of Registrable Securities to be included in such Bronco Demand Registration shall be allocated among the Holders other than Bronco seeking to include their Registrable Securities in the underwriting on a pro rata basis based on the percentage derived by dividing (x) the number of Registrable Securities owned by such Holder by (y) the total number of Registrable Securities owned by such other Holders (excluding Bronco) seeking to include their Registrable Securities in the underwriting. Any Registrable Securities excluded or withdrawn from such underwriting shall be withdrawn from the registration.

(vii)The Partnership may include in any such Demand Registration other Partnership securities for sale for its own account or for other Holders as provided herein; provided that if the managing underwriter for the offering determines that the number of securities proposed to be offered in such offering would have a material adverse effect on the marketability of such offering, then the Registrable Securities to be sold by the Holders shall be included in such registration before any Partnership securities proposed to be sold for the account of the Partnership or any other Person.

(viii)Subject to the limitations contained in this Agreement, the Partnership shall effect any Demand Registration on Form S-3 (except if the Partnership is not then eligible to register for resale the Registrable Securities on Form S-3, in which case such Demand Registration shall be effected on another appropriate form for such purpose pursuant to the Securities Act) and if the Partnership becomes, and is at the time of its receipt of a Demand Notice, a WKSI, the Demand Registration for any offering and selling of Registrable Securities through a firm commitment underwriting shall be effected pursuant to an Automatic Shelf Registration Statement, which shall be on Form S-3 or any equivalent or successor form under the Securities Act (if available to the Partnership).

(ix)Without limiting Section 3, in connection with any Demand Registration pursuant to and in accordance with this Section 2(b), the Partnership shall (A) promptly prepare and file or cause to be prepared and filed: (1) such additional forms, amendments, supplements, prospectuses, certificates, letters, opinions and other documents, as may be necessary or advisable to register or qualify the securities subject to such Demand Registration, including under the securities laws of such states as the Holders shall reasonably request; provided, however, that no such qualification shall be required in any jurisdiction where, as a result thereof, the Partnership would become subject to general service of process or to taxation or qualification to do business in such jurisdiction solely as a result of registration and (2) such forms, amendments, supplements, prospectuses, certificates, letters, opinions and other documents as may be necessary to apply for listing or to list the Registrable Securities subject to such Demand

9

Registration on the Trading Market and (B) do any and all other acts and things that may be necessary or appropriate or reasonably requested by the Holders to enable the Holders to consummate a public sale of such Registrable Securities in accordance with the intended timing and method or methods of distribution thereof.

(x)In the event a Holder transfers Registrable Securities included on a Registration Statement and such Registrable Securities remain Registrable Securities following such transfer, at the request of such Holder, the Partnership shall amend or supplement such Registration Statement or related Prospectus as may be necessary in order to enable such transferee to offer and sell such Registrable Securities pursuant to such Registration Statement.

(c)Piggyback Registration.

(i)If the Partnership shall at any time propose to file a Registration Statement, other than pursuant to a Demand Registration, for an offering of Common Units for cash (whether in connection with a public offering of Common Units by the Partnership, a public offering of Common Units by unitholders, or both, but excluding an offering relating solely to an employee benefit plan, an offering relating to a transaction on Form S-4 or an offering on any registration statement form that does not permit secondary sales), the Partnership shall promptly notify all Holders of such proposal reasonably in advance of (and in any event at least ten Business Days before) the anticipated initial filing date of such Registration Statement (the “Piggyback Notice”). The Piggyback Notice shall offer the Holders the opportunity to include for registration in such Registration Statement the number of Common Units constituting Registrable Securities as they may request (a “Piggyback Registration”). The Partnership shall use reasonable best efforts to include in each such Piggyback Registration such Registrable Securities for which the Partnership has received written requests within five Business Days after mailing of the Piggyback Notice (“Piggyback Request”) for inclusion therein. If a Holder decides not to include all of its Common Units constituting Registrable Securities in any Registration Statement thereafter filed by the Partnership, such Holder shall nevertheless continue to have the right to include any Registrable Securities in any subsequent registration statement or registration statements as may be filed by the Partnership with respect to offerings of Common Units, all upon the terms and conditions set forth herein.

(ii)If the Registration Statement under which the Partnership gives notice under this Section 2(c) is for an underwritten offering, the Partnership shall so advise the Holders of Registrable Securities. In such event, the right of any Holder to be included in a registration pursuant to this Section 2(c) shall be conditioned upon such Holder's participation in such underwriting and the inclusion of such Holder's Registrable Securities in the underwriting to the extent provided herein. If the managing underwriter or managing underwriters of such offering advise the Partnership that, in their opinion, the inclusion of all of such Holders' Registrable Securities in the subject Registration Statement would have a material adverse effect on the marketability of the offering, then the Partnership shall so advise all Holders of Registrable Securities that would otherwise be underwritten pursuant hereto, and the number of Registrable Securities that may be included in the underwriting shall be reduced to equal the number of Registrable Securities that such managing underwriter or managing underwriters advise the Partnership can be sold without having such material adverse effect. The aggregate number of Registrable Securities to be included in such underwriting as a result of the reduction described

10

in the immediately preceding sentence shall be allocated (i) first to Bronco based on the number of Registrable Securities proposed to be sold by Bronco, and, subject to the Partnership's need for capital and without reducing the number of Common Units to be issued by the Partnership in such underwritten offering, Bronco shall have the right to include a number of Registrable Securities equal to 25% of the total number of Common Units proposed to be sold, and (ii) second, among the other Holders seeking to include their Registrable Securities in the underwriting on a pro rata basis based on the percentage derived by dividing (x) the number of Registrable Securities owned by such Holder by (y) the total number of Registrable Securities owned by such other Holders (excluding Bronco) seeking to include their Registrable Securities in the underwriting. If any Holder disapproves of the terms of any such underwriting, such Holder may elect to withdraw therefrom by written notice to the Partnership and the managing underwriter(s) delivered on or prior to the time of pricing of such offering. For the avoidance of doubt, the securities to be sold for the account of the Partnership pursuant to this section 2(c) shall be included in such underwriting before any Registrable Securities to be sold by any Holders or any other Person. Any Registrable Securities excluded or withdrawn from such underwriting shall be withdrawn from the registration.

(iii)The Partnership shall have the right to terminate or withdraw any registration initiated by it under this Section 2(c) prior to the Effective Date of such Registration Statement whether or not any Holder has elected to include Registrable Securities in such Registration Statement. The registration expenses of such withdrawn registration (including reasonable attorneys fees of the Holders that elected to include Registrable Securities in such Registration Statement) shall be borne by the Partnership in accordance with Section 5 hereof.

(d)General Provisions.

(i)All registration rights granted under this Section 2 shall continue to be applicable with respect to any Holder for so long as may be required for each such Holder to sell all of the Registrable Securities held by such Holder as provided in this Agreement.

(ii)Any Demand Notice or Piggyback Request shall (i) specify the Registrable Securities intended to be offered and sold by the Holder making the request, (ii) express such Holder's present intent to offer such Registrable Securities for distribution, (iii) describe the nature or method of the proposed offer and sale of Registrable Securities, and (iv) contain the undertaking of such Holder to provide all such information and materials and take all action as may reasonably be required in order to permit the Partnership to comply with all applicable requirements in connection with the registration of such Registrable Securities.

(iii)The Partnership has not entered into any agreement which (a) conflicts with the provisions hereof in any material respect or (b) would allow any Holder to include Registrable Securities in any Registration Statement filed by the Partnership on a basis that is superior or more favorable in any material respect to the rights granted to the Holders hereunder.

(iv)Notwithstanding any provision of this Agreement to the contrary, the Partnership may voluntarily suspend the effectiveness of any Shelf Registration Statement or may otherwise require the discontinuance of offers under the Shelf Registration Statement for a period of up to 90 days if the Conflicts Committee, proceeding in good faith, determines the

11

offering of any Registrable Securities pursuant to such Shelf Registration Statement would require an Adverse Disclosure (a “Suspension”); provided, however, that in no event shall the Partnership effect Suspensions under this Section 2(d)(iv) for more than an aggregate of 180 days in any 12‑month period. The Partnership shall notify each Holder eligible to sell Registrable Securities under such Shelf Registration Statement promptly of any Suspensions and, upon receipt of such notice, each such Holder shall forthwith discontinue disposition of such Registrable Securities under such Shelf Registration Statement until such Holder's receipt of the copies of the supplemental Prospectus or amended Shelf Registration Statement or until it is advised in writing by the Partnership that the use of the applicable Prospectus may be resumed, and, in either case, has received copies of any additional or supplemental filings that are incorporated or deemed to be incorporated by reference in such Shelf Registration Statement. In addition, the Partnership shall promptly notify each Holder of the termination or lifting of any such Suspension.

3.Registration Procedures. The procedures to be followed by the Partnership and each Holder electing to sell Registrable Securities included in a Registration Statement pursuant to this Agreement, and the respective rights and obligations of the Partnership and such Holders, with respect to the preparation, filing and effectiveness of such Registration Statement, are as follows:

(a)The Partnership will, at least five Business Days prior to the anticipated filing of a Registration Statement or any related Prospectus or any amendment or supplement thereto (other than amendments and supplements filed principally for the purpose of naming Holders and providing information with respect thereto), (i) furnish to such Holders copies of all such documents proposed to be filed and (ii) give good faith consideration to such comments as any Holder reasonably shall propose.

(b)The Partnership will use reasonable best efforts to (i) prepare and file with the Commission such amendments, including post-effective amendments, and supplements to each Registration Statement and the Prospectus used in connection therewith as may be necessary under applicable law to keep such Registration Statement continuously effective with respect to the disposition of all Registrable Securities covered thereby for its Effectiveness Period and, subject to the limitations contained in this Agreement, prepare and file with the Commission such additional Registration Statements in order to register for resale under the Securities Act all of the Registrable Securities held by the applicable Holders; (ii) cause the related Prospectus to be amended or supplemented by any required prospectus supplement, and as so supplemented or amended to be filed pursuant to Rule 424; and (iii) respond to any comments received from the Commission with respect to each Registration Statement or any amendment thereto and provide such Holders true and complete copies of all correspondence from and to the Commission relating to such Registration Statement that pertains to such Holders as Selling Holders.

(c)The Partnership will comply in all material respects with the provisions of the Securities Act and the Exchange Act with respect to the Registration Statements and the disposition of all Registrable Securities covered by each Registration Statement.

12

(d)The Partnership will use reasonable best efforts to notify such Holders promptly: (i)(A) when the Commission notifies the Partnership whether there will be a “review” of such Registration Statement and whenever the Commission comments in writing on such Registration Statement (in which case the Partnership shall provide true and complete copies thereof and all written responses thereto to each of such Holders and in good faith consider such Holder's comments in the Registration Statement); and (B) with respect to each Registration Statement or any post-effective amendment thereto, when the same has been declared effective; (ii) of any request by the Commission or any other federal or state governmental authority for amendments or supplements to a Registration Statement or Prospectus or for additional information that pertains to such Holders as sellers of Registrable Securities; (iii) of the issuance by the Commission of any stop order suspending the effectiveness of a Registration Statement covering any or all of the Registrable Securities or the initiation of any Proceedings for that purpose; (iv) of the receipt by the Partnership of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Registrable Securities for sale in any jurisdiction, or the initiation or threatening of any Proceeding for such purpose; and (v) of the occurrence of (but not the nature or details concerning) any event or passage of time that makes any statement made in such Registration Statement or Prospectus or any document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires any revisions to such Registration Statement, Prospectus or other documents so that, in the case of such Registration Statement or the Prospectus, as the case may be, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading (provided, however, that no notice by the Partnership shall be required pursuant to this clause (v) in the event that the Partnership either promptly files a prospectus supplement to update the Prospectus or a Form 8-K or other appropriate Exchange Act report that is incorporated by reference into the Registration Statement, which in either case, contains the requisite information that results in such Registration Statement no longer containing any untrue statement of material fact or omitting to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading).

(e)The Partnership will use reasonable best efforts to avoid the issuance of, or, if issued, obtain the withdrawal of (i) any order suspending the effectiveness of a Registration Statement, or (ii) any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction, at the earliest practicable time, or if any such order or suspension is made effective during any Suspension period, at the earliest practicable time after the Suspension period is over.

(f)During the Effectiveness Period, the Partnership will furnish to each such Holder, without charge, at least one conformed copy of each Registration Statement and each amendment thereto and all exhibits to the extent requested by such Holder (including those incorporated by reference) promptly after the filing of such documents with the Commission; provided, that the Partnership will not have any obligation to provide any document pursuant to this clause that is available on the Commission's EDGAR system.

(g)The Partnership will promptly deliver to each Holder, without charge, as many copies of each Prospectus or Prospectuses (including each form of Prospectus) and each

13

amendment or supplement thereto as such Holder may reasonably request during the Effectiveness Period. The Partnership consents to the use of such Prospectus and each amendment or supplement thereto by each of the Selling Holders in connection with the offering and sale of the Registrable Securities covered by such Prospectus and any amendment or supplement thereto.

(h)The Partnership will have caused or will cause, as the case may be, all Registrable Securities registered pursuant to this Agreement to be listed on the Trading Market and will have provided or will provide, as the case may be, a transfer agent and registrar for Registrable Securities covered by a Registration Statement not later than the Effective Date of such Registration Statement and for as long as Registrable Securities covered by a Registration Statement remain outstanding.

(i)The Partnership will cooperate with such Holders to facilitate the timely preparation and delivery of certificates representing Registrable Securities to be delivered to a transferee pursuant to a Registration Statement, which certificates shall be free of all restrictive legends indicating that the Registrable Securities are unregistered or unqualified for resale under the Securities Act, Exchange Act or other applicable securities laws, and to enable such Registrable Securities to be in such denominations and registered in such names as any such Holder may request in writing.

(j)Upon the occurrence of any event contemplated by Section 3(d)(v), as promptly as reasonably possible, the Partnership will prepare a supplement or amendment, including a post-effective amendment, if required by applicable law, to the affected Registration Statement or a supplement to the related Prospectus or any document incorporated or deemed to be incorporated therein by reference, and file any other required document so that, as thereafter delivered, no Registration Statement nor any Prospectus will contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(k)Such Holders may distribute the Registrable Securities by means of an underwritten offering; provided that (i) such Holders provide written notice to the Partnership of their intention to distribute Registrable Securities by means of an underwritten offering, (ii) the right of any Holder to include such Holder's Registrable Securities in such registration shall be conditioned upon such Holder's participation in such underwriting and the inclusion of such Holder's Registrable Securities in the underwriting to the extent provided herein, (iii) the managing underwriter or managing underwriters thereof shall either be one of the lead underwriters of the Initial Public Offering or otherwise be subject to the approval of the Partnership (which shall not be unreasonably withheld), (iv) each Holder participating in such underwritten offering agrees to enter into an underwriting agreement in customary form and sell such Holder's Registrable Securities on the basis provided in any reasonable underwriting arrangements approved by the Partnership and (v) each Holder participating in such underwritten offering completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably and customarily required under the terms of such underwriting arrangements, provided, that, no Holder included in any underwritten registration shall be required to make any representations or warranties to the Partnership or the

14

underwriters (other than representations and warranties regarding such Holder) or to undertake any indemnification obligations to the Partnership or the underwriters except as provided in Section 6. The Partnership hereby agrees with each Holder that, in connection with any underwritten offering in accordance with the terms hereof, it will negotiate in good faith and execute all indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements, including using reasonable best efforts to procure customary legal opinions and auditor “comfort” letters.

(l)In the event such Holders seek to complete an underwritten offering, for a reasonable period prior to the filing of any Registration Statement and throughout the Effectiveness Period, the Partnership will make available upon reasonable notice at the Partnership's principal place of business or such other reasonable place for inspection by the Selling Holder and the managing underwriter or managing underwriters selected in accordance with Section 3(k) such financial and other information and books and records of the Partnership, and cause the officers, employees, counsel and independent certified public accountants of the Partnership to respond to such inquiries, as shall be reasonably necessary (and in the case of counsel, not violate an attorney-client privilege in such counsel's reasonable belief) to conduct a reasonable investigation within the meaning of Section 11 of the Securities Act.

(m)In connection with any registration of Registrable Securities pursuant to this Agreement, the Partnership will take such reasonable best actions as are necessary or advisable in order to expedite or facilitate the disposition of Registrable Securities by such Holders, including using reasonable best efforts to cause appropriate officers and employees to be available, on a customary basis and upon reasonable notice, to meet with prospective investors in presentations, meetings and road shows.

(n)The Partnership will have no obligation to include in a Registration Statement or Piggyback Registration Registrable Securities of a Holder who has failed to timely furnish such information requested in writing by the Partnership no less than 10 days prior to the effective date of the Registration Statement, which, in the opinion of counsel to the Partnership, is reasonably required in order for the Registration Statement or related Prospectus to comply with the Securities Act, provided that if the Registration Statement is not yet effective, the Partnership agrees to amend the Registration Statement to include the Registrable Securities of a Holder when such information is provided.

(o)In connection with any Initial Public Offering of Common Units, each Holder hereby agrees that such Holder shall enter into a standard lock-up agreement covering such Registrable Securities and for a period specified by the managing underwriter or managing underwriters (the “Lock-Up Period”); provided, however, that the Lock-Up Period with respect to Bronco shall not exceed 180 days following the closing date of the offering of Common Units. In addition, if (A) during the last 17 days of the Lock-Up Period, the Partnership issues an earnings release or material news or a material event relating to the Partnership occurs or (B) prior to the expiration of the Lock-Up Period, the Partnership announces that it will release earnings results during the 16-day period beginning on the last day of the Lock-Up Period, then the restrictions imposed by this Section 3(o) shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the announcement of the material news or the occurrence of the material event. Each Holder agrees to execute and deliver such

15

other agreements as may be reasonably requested by the Partnership or the underwriter which are consistent with the foregoing or which are necessary to give further effect thereto. In addition, if requested by the Partnership or the representative of the underwriters of Common Units, each Holder shall provide, within five Business Days of such request, such information as may be reasonably and customarily required by the Partnership or such representative in connection with the completion of any public offering of the Common Units pursuant to a Registration Statement, unless such Holder reasonably believes that such information constitutes material and non-public information or such Holder is otherwise subject to confidentiality obligations with respect to the requested information. The obligations described in this Section 3(o) shall not apply to a registration relating solely to employee benefit plans on Form S-1 or Form S-8 or similar forms that may be promulgated in the future, or a registration relating solely to a transaction on Form S-4 or similar forms that may be promulgated in the future. The Partnership may impose stop-transfer instructions with respect to the Common Units subject to the foregoing restriction until the end of the Lock-Up Period.

(p)The Partnership will use its reasonable best efforts to comply with the securities laws of the United States and other applicable jurisdictions and all applicable rules and regulations of the Commission and comparable governmental agencies in other applicable jurisdictions and make generally available to the Holders, in each case as soon as practicable after the Effective Date (it being understood that the Partnership shall have until at least 410 days or, if the fourth quarter following the fiscal quarter that includes the Effective Date is the last fiscal quarter of the Partnership's fiscal year, 455 days after the end of the Partnership's then-current fiscal quarter), an earnings statement of the Partnership (which need not be audited) complying with the provisions of Section 11(a) of the Securities Act (including, at the option of the Partnership, Rule 158).

4.Bronco IPO Consultation. The Board of Directors will determine all matters related to the Initial Public Offering and the related registration process. The Parties acknowledge and agree that the Sponsor Parties and Bronco each desire for the Initial Public Offering to be implemented upon terms and conditions that are consistent with prevailing market terms for the public offering of equity securities of comparable master limited partnerships at the time such Initial Public Offering is implemented. In furtherance of this desire, the Sponsor Parties, the General Partner and the Partnership agree that such IPO Registration shall be implemented in good faith at such prevailing market terms, including with respect to the applicable distribution coverage ratio, as determined in consultation with the managing underwriter at the time of the Initial Public Offering. For so long as Bronco holds at least the Initial Bronco Amount, Bronco shall be involved in planning and negotiating the terms of the Initial Public Offering or such other registration process, including, without limitation, in determining the percentage of the Partnership to be offered to the public and the valuation metrics associated with the Initial Public Offering or such registration process. To that end, Bronco will be included in any applicable working group list with respect to an Initial Public Offering and will be given notice of, and an opportunity to participate in, all discussions between the Partnership and/or any Sponsor Party or Affiliate of a Sponsor Party and any banker, underwriter or other third party regarding management preparation, pricing and other material matters related to the Initial Public Offering and the related registration process. Notwithstanding anything in this Agreement to the contrary, the rights provided to Bronco in the

16

two immediately preceding sentences shall not be transferable in connection with any transfer of Registrable Securities by Bronco.

5.Registration Expenses. All Registration Expenses incident to the Parties' performance of or compliance with their respective obligations under this Agreement or otherwise in connection with any IPO Registration, Demand Registration or Piggyback Registration (excluding any Selling Expenses) shall be borne by the Partnership, whether or not any Registrable Securities are sold pursuant to a Registration Statement. “Registration Expenses” shall include, without limitation, (i) all registration and filing fees (including fees and expenses (A) with respect to filings required to be made with the Trading Market, (B) in connection with any filings required to be made with the Financial Industry Regulatory Authority, Inc. and (C) in compliance with applicable state securities or “Blue Sky” laws), (ii) printing expenses (including expenses of printing certificates for Common Units and of printing prospectuses if the printing of prospectuses is reasonably requested by a Holder included in the Registration Statement), (iii) messenger, telephone and delivery expenses, (iv) fees and expenses of counsel (including local and special), auditors and accountants (including the expenses of any “cold comfort” letters required or incidental to the performance of such obligations) for the Partnership, (v) Securities Act liability insurance, if the Partnership so desires such insurance, (vi) fees and expenses of all other Persons retained by the Partnership in connection with the consummation of the transactions contemplated by this Agreement, (vii) the costs and expenses related to investor presentations on any road show undertaken in connection with the marketing of the Common Units, including, expenses associated with any electronic road show, travel and lodging expenses of the officers and employees of the General Partner or any Group Member, (viii) the costs and expenses of qualifying the Common Units for inclusion in the book-entry settlement system of the DTC and (ix) the fees and expenses of the transfer agent and registrar. Except as provided herein, all Selling Expenses shall be borne by the Selling Holders pro rata in proportion to the number of Registrable Securities sold by each Selling Holder or as they may otherwise agree; provided, however, that any and all reasonable fees and expenses of counsel incurred by Bronco in connection with the IPO Registration shall be borne by the Partnership, provided that such reimbursed fees and expenses shall not, in the aggregate, exceed $250,000 if the IPO Date occurs on or before December 31, 2013, which amount shall increase by $25,000 per quarter (and partial quarter) after December 31, 2013 until the IPO Date occurs.

6.Indemnification.

(a)By the Partnership. If underwriters are engaged in connection with any registration referred to in Section 2, the Partnership shall provide indemnification, representations, covenants, opinions and other assurances to the underwriters in form and substance reasonably satisfactory to such underwriters and the Partnership. In the event of a registration of any Registrable Securities under the Securities Act pursuant to this Agreement, in addition to and not in limitation of the Partnership's obligations under Section 7.7 of the Partnership Agreement, to the fullest extent permitted by applicable law, the Partnership shall indemnify and hold harmless each Selling Holder, its officers, directors and each Person who controls the Holder (within the meaning of the Securities Act), and any agent thereof (collectively, “Indemnified Persons”) from and against any and all losses, claims, damages, liabilities, joint or several, expenses (including legal fees and expenses), judgments, fines,

17

penalties, interest, settlements or other amounts arising from any and all claims, demands, actions, suits or proceedings, whether civil, criminal, administrative or investigative, in which any Indemnified Person may be involved, or is threatened to be involved, as a party or otherwise, under the Securities Act or otherwise (collectively, “Losses”), based upon, arising out of or resulting from any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, preliminary prospectus, final prospectus or issuer free writing prospectus under which any Registrable Securities were registered or sold by such Selling Holder under the Securities Act, or arising out of, based upon or resulting from the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; provided, however, that the Partnership shall not be liable to any Indemnified Person to the extent that any such Loss arises out of, is based upon or results from an untrue statement or alleged untrue statement or omission or alleged omission so made in such Registration Statement, preliminary prospectus, final prospectus or issuer free writing prospectus in reliance upon or in conformity with written information furnished to the Partnership by or on behalf of such Selling Holder specifically for use in the preparation thereof.

(b)By Each Selling Holder. Each Selling Holder agrees, to the fullest extent permitted by law, to severally and not jointly, indemnify and hold harmless the Partnership, the General Partner's officers and its directors and each Person who controls the Partnership (within the meaning of the Securities Act) and any agent thereof to the same extent as the foregoing indemnity from the Partnership to the Selling Holders, but only with respect to information regarding such Selling Holder furnished in writing by or on behalf of such Selling Holder expressly for inclusion in such Registration Statement, preliminary prospectus, final prospectus or free writing prospectus and any indemnification hereunder will be limited to the amount of net proceeds received from the sale of Registrable Securities by such Holder under such Registration Statement.

7.Facilitation of Sales Pursuant to Rule 144.

(a)Upon effectiveness of a Registration Statement with the Commission, the Partnership shall use reasonable best efforts to timely file the reports required to be filed by it under the Exchange Act or the Securities Act (including the reports under Sections 13 and 15(d) of the Exchange Act referred to in subparagraph (c)(1) of Rule 144), and take such further action as any Holder may reasonably request, all to the extent required from time to time to enable the Holders to sell Registrable Securities without registration under the Securities Act within the limitations of the exemption provided by Rule 144.

(b)The Parties agree that, as of the date of this Agreement, it is the intent of the Parties that the ownership, operation and management of the Partnership will be structured so that Bronco will not be considered an “affiliate” (as such term is defined in Rule 144) of the Partnership. In connection therewith on or before the 91st day following the IPO Closing Date, subject to compliance with applicable law and so long as Bronco together with its Affiliates (i) owns less than 15% of the Common Units, and (ii) has no right to designate any member of the Board of Directors, the Partnership will remove any transfer restrictions with respect to Common Units owned by Bronco, including providing such authorizations, directions and legal opinions as may be reasonably requested by the transfer agent that authorize the removal of any

18

restrictive legends on such Common Units and/or directing the transfer agent to issue such Common Units without any such legend upon sale by Bronco of such Common Units.

8.Limitation on Subsequent Registration Rights. From and after the date hereof, the Partnership shall not, without the prior written consent of Bronco (for so long as it is a Holder) and the Holders of a majority of the then outstanding Registrable Securities, enter into any agreement with any current or future holder of any securities of the Partnership that would allow such current or future holder to require the Partnership to include securities in any registration statement filed by the Partnership on a basis that is senior in any way to the registration rights granted to the Initial Holders hereunder.

9.Miscellaneous.

(a)Discontinued Disposition. Each Holder agrees by its acquisition of such Registrable Securities that, upon receipt of a notice from the Partnership of the occurrence of any event of the kind described in clauses (ii) through (v) of Section 3(d), such Holder shall forthwith discontinue disposition of such Registrable Securities under the Registration Statement until such Holder's receipt of the copies of the supplemental Prospectus or amended Registration Statement or until it is advised in writing by the Partnership that the use of the applicable Prospectus may be resumed, and, in either case, has received copies of any additional or supplemental filings that are incorporated or deemed to be incorporated by reference in such Prospectus or Registration Statement. The Partnership may provide appropriate stop orders to enforce the provisions of this Section 9(a).

(b)Recapitalization, Exchanges, etc. Affecting the Common Units. The provisions of this Agreement shall apply to the full extent set forth herein with respect to any and all Partnership Interests or any successor or assign of the Partnership (whether by merger, consolidation, sale of assets or otherwise) which may be issued in respect of, in exchange for or in substitution of, the Registrable Securities, including any equity securities that may be issued in exchange for Registrable Securities in connection with any merger, consolidation or other business combination involving the Partnership and any of its subsidiaries, and shall be appropriately adjusted for combinations, recapitalizations and the like occurring after the date of this Agreement. The Partnership will not take any action, or permit any change to occur, with respect to the terms of its securities that would materially and adversely affect the ability of the Holders to include Registrable Securities in a registration undertaken pursuant to this Agreement or that would adversely affect the marketability of such Registrable Securities in any such registration.

(c)Change of Control. The Partnership shall not merge, consolidate or combine with any other Person unless the agreement providing for such merger, consolidation or combination expressly provides for the continuation of the registration rights specified in this Agreement with respect to the Registrable Securities or other equity securities issued pursuant to such merger, consolidation or combination.

(d)Specific Performance. Damages in the event of breach of this Agreement by a Party may be difficult, if not impossible, to ascertain, and it is therefore agreed that each such Party, in addition to and without limiting any other remedy or right it may have, will have

19

the right to an injunction or other equitable relief in any court of competent jurisdiction, enjoining any such breach, and enforcing specifically the terms and provisions hereof, and each of the Parties hereby waives any and all defenses it may have on the ground of lack of jurisdiction or competence of the court to grant such an injunction or other equitable relief (including the requirement to post bond). The existence of this right will not preclude any such Party from pursuing any other rights and remedies at law or in equity which such Party may have.

(e)Amendments. This Agreement may be amended only by means of a written amendment signed by (i) the Partnership, (ii) the Holders of 66 2/3% of the then-outstanding Registrable Securities and (iii) for so long as it is a Holder, Bronco; provided, however, that no such amendment shall adversely affect the rights of any Holder hereunder without the consent of such Holder.

(f)Notices. All notices, demands, requests and other communications required or permitted to be given or made under this Agreement shall be in writing and shall be deemed given or made when delivered in person or when sent by first class United States mail or by other means of written communication to the Person at the address described below:

(i)if to a Holder, at (A) the most current mailing or email address given by such Holder to the Partnership in accordance with the provisions of this Section 9(f), which addresses initially are, with respect to the Holders, set forth opposite each Holder's name on the signature page hereto;

(ii)if to a transferee of a Holder, to such Holder at the mailing address or email address provided pursuant to this Section 9(f); and

(iii)if to the Partnership, to each of the following: (A) 1111 Louisiana Street, Houston, Texas 77002 or Email: Gary.Whitlock@CenterPointEnergy.com, Attention: Chief Financial Officer and (B) 321 North Harvey, P.O.

The terms “in writing,” “written communications,” “written notice” and words of similar import shall be deemed satisfied under this Agreement by use of email and other forms of electronic communication. All such notices and communications shall be deemed to have been received (i) at the time delivered by hand, if personally delivered; (ii) the date of transmission, if such notice or communication is delivered via facsimile or email prior to 5:00 p.m. Central Time on a Business Day; (iii) the first Business Day after the date of transmission, if such notice or communication is delivered via facsimile or email (A) on a day other than a Business Day or (B) later than 5:00 p.m. Central Time on a Business Day and earlier than 11:59 p.m. Central Time on such date; or (iv) when actually received, if sent by any other means.

(g)Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the Parties hereto and their heirs, executors, administrators, successors, legal representatives and permitted assigns. Except as provided in this Section 9(g), this Agreement, and any rights or obligations hereunder, may not be assigned without the prior written consent of

20

the Partnership and the Holders. Notwithstanding anything in the foregoing to the contrary (but subject to the last sentence of Section 4), the registration rights of a Holder pursuant to this Agreement with respect to all or any portion of its Registrable Securities may be assigned without such consent (but only with all related obligations) with respect to such Registrable Securities (and any Registrable Securities issued as a dividend or other distribution with respect to, in exchange for or in replacement of such Registrable Securities) by such Holder to a transferee of such Registrable Securities; provided (i) the transfer of the underlying Registrable Securities was made in accordance with the terms of the Partnership Agreement; (ii) the Partnership is, promptly after such transfer, furnished with written notice of the name, mailing address and email address of such transferee or assignee and the Registrable Securities with respect to which such registration rights are being assigned; and (iii) such transferee or assignee agrees in writing to be bound by and subject to the terms set forth in this Agreement. The Partnership may not assign its respective rights or obligations hereunder without the prior written consent of each of the Holders.

(h)Counterparts. This Agreement may be executed in counterparts, all of which together shall constitute an agreement binding on all the Parties, notwithstanding that all such Parties are not signatories to the original or the same counterpart.

2.4Indemnification Procedures.

(a)Opco agrees that promptly after it becomes aware of facts giving rise to a claim for indemnification under this Article II, it will provide notice thereof in writing to the applicable Indemnifying Party, specifying the nature of and specific basis for such claim; provided,

8

however, that in the event GP LLC elects not to cause Opco to pursue a claim for indemnification that Opco is entitled to pursue under this Article II that could result in the payment of any amount by the Indemnifying Party, Bronco shall have the right to cause GP LLC to cause Opco to pursue such claim by delivering written notice of Bronco's election to GP LLC until the Bronco Fall-Away Date. Promptly following the receipt by GP LLC of Bronco's written election pursuant to the foregoing proviso, Opco will provide notice thereof in writing to the applicable Indemnifying Party, specifying the nature of and specific basis for such claim, and GP LLC shall thereafter cause Opco to diligently pursue such claim in accordance with this Section 2.4. If Opco fails to provide such notice to the Indemnifying Party within ten (10) Business Days or if Opco fails to diligently pursue such claim in accordance with this Section 2.4, then Bronco may notify the Indemnifying Party of such claim directly and may control the pursuit of such claim against the Indemnified Party on behalf of Opco. Both CNP and OGE agree to cause their designated members of the board of directors of GP LLC to approve the actions reasonably requested by Bronco with respect to any such claim.

(b)The Indemnifying Party (or Indemnifying Parties) shall have the right to control at its sole cost and expense all aspects of the defense of (and any counterclaims with respect to) any claims brought against the Indemnified Party that are covered by the indemnification under this Article II, including, without limitation, the selection of counsel, determination of whether to appeal any decision of any court and the settling of any such matter or any issues relating thereto; provided, however, that no such settlement shall be entered into without the prior written consent of the Indemnified Party unless it includes a full release of the Indemnified Party from such matter or issues, as the case may be.

(c)The Indemnified Party agrees to cooperate fully with each Indemnifying Party, with respect to all aspects of the defense of any claims covered by the indemnification under this Article II, including, without limitation, the prompt furnishing to each Indemnifying Party of any correspondence or other notice relating thereto that the Indemnified Party may receive, permitting the name of the Indemnified Party to be utilized in connection with such defense, the making available to each Indemnifying Party of any files, records or other information of the Indemnified Party that any Indemnifying Party reasonably considers relevant to such defense, the granting to the Indemnifying Party of reasonable access rights to the properties and facilities of the Indemnified Party and the making available to each Indemnifying Party of any employees of the Indemnified Party; provided, however, that in connection therewith each Indemnifying Party agrees to use reasonable efforts to minimize the impact thereof on the operations of the Indemnified Party and further agrees to maintain the confidentiality of all files, records, and other information furnished by the Indemnified Party pursuant to this Section 2.4. In no event shall the obligation of the Indemnified Party to cooperate with each Indemnifying Party as set forth in the immediately preceding sentence be construed as imposing upon the Indemnified Party an obligation to hire and pay for counsel in connection with the defense of any claims covered by the indemnification set forth in this Article II; provided, however, that the Indemnified Party may, at its own option, cost and expense, hire and pay for counsel in connection with any such defense. The Indemnifying Party agrees to keep any such counsel hired by the Indemnified Party informed as to the status of any such defense, but the Indemnifying Party shall have the right to retain sole control over such defense.

9

(d)In determining the amount of any Losses for which the Indemnified Party is entitled to indemnification under this Agreement, the gross amount of the indemnification will be reduced by (i) any cash insurance proceeds realized by the Indemnified Party, and such correlative insurance benefit shall be net of any incremental insurance premiums that become due and payable by the Indemnified Party as a result of such claim and (ii) all cash amounts recovered by the Indemnified Party under contractual indemnities from third Persons.

(e)To the extent that any indemnification claim under this Article II involves a claim where Opco, on the one hand, and either CNP or OGE, on the other hand, are adverse, Opco's rights and obligations shall be controlled by the Disinterested Directors. Both CNP and OGE agree to cause their designated members of the board of directors of GP LLC who are not Disinterested Directors to approve the actions of the Disinterested Directors with respect to any such claim.

2.5Exclusive Remedy. The indemnification provisions of this Article II will be the exclusive remedy following the Closing for any breaches or alleged breaches of any representation, warranty or covenant of the Master Formation Agreement, except with respect to claims or causes of action arising from breaches or alleged breaches of Sections 6.2(b), 6.2(c), 6.5(c), 6.7(a)(ii), 6.7(b)(ii), 6.8, 6.13, 6.14, 6.15, 6.18 and 9.3 and Article X of the Master Formation Agreement or from fraud or willful misconduct. Each of the Parties, on behalf of itself and its members, officers, directors, employees, stockholders, equityholders, partners and Affiliates, agrees not to bring any actions or proceedings, at law, equity or otherwise against any other Party or its members, officers, directors, employees, shareholders, partners and Affiliates, in respect of any breaches or alleged breaches of any representation, warranty or covenant of the Master Formation Agreement or the transactions contemplated thereby, except pursuant to the express provisions of this Article II and except with respect to claims or causes of action arising from fraud or willful misconduct.

2.6Other Indemnification Matters.

(a)For the avoidance of doubt, except as expressly set forth in this Article II, there is no monetary cap on the amount of indemnity coverage provided by any Indemnifying Party under this Article II.

(b)NOTWITHSTANDING ANYTHING HEREIN TO THE CONTRARY, IN NO EVENT SHALL ANY PARTY'S INDEMNIFICATION OBLIGATION HEREUNDER COVER OR INCLUDE CONSEQUENTIAL, INDIRECT, INCIDENTAL, PUNITIVE, EXEMPLARY, SPECIAL OR SIMILAR DAMAGES OR LOST PROFITS SUFFERED BY ANY OTHER PARTY ENTITLED TO INDEMNIFICATION UNDER THIS AGREEMENT.

(c)THE FOREGOING INDEMNITIES ARE INTENDED TO BE ENFORCEABLE AGAINST THE PARTIES IN ACCORDANCE WITH THE EXPRESS TERMS AND SCOPE THEREOF NOTWITHSTANDING ANY EXPRESS NEGLIGENCE RULE OR ANY SIMILAR DIRECTIVE THAT WOULD PROHIBIT OR OTHERWISE LIMIT INDEMNITIES BECAUSE OF THE SOLE, CONCURRENT, ACTIVE OR PASSIVE NEGLIGENCE, STRICT LIABILITY OR FAULT OF ANY OF THE INDEMNIFIED PARTIES.

In the event Opco does not so elect, such Sponsor Party shall be permitted to own and operate such Restricted Businesses and such Restricted Businesses shall not be included in the calculation of the aggregate value of such Sponsor Party's Restricted Businesses for purposes of clause (B) above; provided, however, that if the fair market value of the Midstream Operations included in the Restricted Business in a Covered Acquisition (as determined in good faith by the Board of Directors of the acquiring Sponsor Party) is greater than 66 2/3% of the fair market value of the Covered Acquisition (as determined in good faith by the Board of Directors of the acquiring Sponsor Party), then the acquiring Sponsor Party shall use commercially reasonable efforts to dispose of the Restricted Business within 24 months of the date on which Opco's option to purchase pursuant to this Section 3.1(b) expired.

(c)Except as set forth in this Section 3.1, no Party shall have any right to seek to enjoin, restrict or prevent any transaction undertaken by a Sponsor Party due to the fact such transaction involves Midstream Operations.

11

(d)The Sponsor Party obligations set forth in this Section 3.1 shall not restrict or otherwise encumber any Person that acquires a Sponsor Party or such acquiror's Subsidiaries (other than the Sponsor Party and its Subsidiaries).

(e)For purposes of this Section 3.1, “Allocated Value” shall mean (i) with respect to any transaction in which there is a bona fide value specifically allocated to the Restricted Business, the value so allocated in such transaction, or (ii) with respect to any transaction in which there is no such allocation of value to the Restricted Business, (A) the value agreed between the acquiring Sponsor Party and Opco (subject to any applicable approvals for a Related Party Transaction) or (B) if there is no agreement on value, then the acquiring Sponsor Party and Opco shall submit the determination of the “Allocated Value” to arbitration by a mutually agreed nationally recognized investment bank which shall determine such matter (the arbitration shall be “baseball” arbitration, with each party submitting a proposed resolution of the “Allocated Value” and the arbitrator selecting the proposal of one of the parties).

(f)Opco's rights and obligations under this Section 3.1 shall be controlled by the Disinterested Directors. Both CNP and OGE agree to cause their designated members of the board of directors of GP LLC who are not Disinterested Directors to approve the actions of the Disinterested Directors with respect to any such transaction.

ARTICLE IV

ADDITIONAL AGREEMENTS

4.1CERC Indenture.

(a)Until the earlier of (i) January 15, 2014 and (ii) the date CERC's 5.95% Senior Notes due 2014 and 7.875% Senior Notes due 2013 are no longer outstanding, Opco shall, and shall cause its Subsidiaries to, comply with the Restrictions on Liens and Restrictions on Sale and Leaseback Transaction covenants (the “Fall Away Covenants”) in the CERC Indenture.

(b)For so long as Opco is a “subsidiary” (as defined in the CERC Indenture) of CERC, Opco shall, and shall cause its Subsidiaries to, subject to Section 4.1(a), comply with the restrictions contained in the CERC Indenture as of the date hereof and applicable to a “subsidiary” (as defined in the CERC Indenture) of CERC, other than the Fall Away Covenants.

4.2Confidentiality Obligations of Bronco. Bronco acknowledges that, from time to time, it may receive information (including by virtue of the observation rights granted to Bronco in Section 3.4 of the Partnership Agreement) from or regarding another Party, another Party's customers or another Party's Affiliates in the nature of trade secrets or secret or proprietary information or information that is otherwise confidential, the release of which may be damaging to the Party or its Affiliates, as applicable, or Persons with which they do business (such information referred to herein as “Confidential Information”). Notwithstanding the foregoing, “Confidential Information” shall not include (x) information that Bronco has received from a source independent of such Party and that Bronco reasonably believes such source obtained without breach of any obligation of confidentiality, (y) public information or (z) information that is independently developed by Bronco or its Affiliates without reliance on the Confidential Information. Bronco shall hold in strict confidence any Confidential Information it receives and

12

may not disclose any Confidential Information to any Person other than another Party, except for disclosures (i) to comply with any Laws (including applicable stock exchange or quotation system requirements), (ii) to Bronco and its Affiliates, and its and their respective officers, directors, employees, agents, advisers or representatives, but only if the recipients of such information have agreed to be bound by confidentiality provisions that are no less stringent than those set forth in this Section 4.2, (iii) to existing and prospective lenders, existing and prospective investors, attorneys, accountants, consultants and other representatives of Bronco or its Affiliates with a need to know such information (including a need to know for Bronco's own purposes), provided, however, that Bronco shall be responsible for such representatives' use and disclosure of any such information, or (iv) in connection with any proposed “transfer” (as defined in the Partnership Agreement) of Bronco's “Units” (as defined in the Partnership Agreement), to Persons to which such interest may be transferred as permitted by the Partnership Agreement, but only if the recipients of such information have agreed in writing to be bound by confidentiality provisions that are no less stringent than those set forth in this Section 4.2. Bronco shall not use any Confidential Information, and shall restrict any of its Affiliates, officers, directors, employees, agents, advisers or representatives to whom Confidential Information has been disclosed pursuant to this Section 4.2 from using any such Confidential Information, for the benefit of any Person (other than a Group Member) in which Bronco or an Affiliate of Bronco has an economic interest in any manner that could have a material detriment on any Group Member. The obligations set forth in the preceding sentence shall expire on the date that is two (2) years after the Bronco Fall-Away Date; provided, that if, prior to the Bronco Fall-Away Date, Opco notifies Bronco that specified Confidential Information is subject to a contractual obligation of Opco to cause Persons that receive such Confidential Information not to use such Confidential Information in the manner set forth in the preceding sentence for a longer period, then the obligations of Bronco in the preceding sentence shall remain in effect with respect to such specified Confidential Information until the expiration of such longer period.

4.3Use of Names and Insignia. Except as set forth in this Section 4.3, Opco agrees that from and after the Closing Date, none of Opco or its Subsidiaries will directly or indirectly use or otherwise exploit, in connection with any business activities, any service marks, trademarks, trade names, trade dress, Internet domain names, identifying symbols, logos, emblems, signs or insignia related thereto or containing or comprising the foregoing, including any word or logo confusingly similar thereto, containing the words “CenterPoint Energy,” “OGE” or “Enogex” or any abbreviations or derivations thereof (the “Subject Marks”). As soon as is reasonably practicable following the selection of a new name by Opco, but in any event within one year following the Closing Date, Opco and its Subsidiaries will cease to use the Subject Marks and use commercially reasonable efforts to remove the Subject Marks from all entity names and assets of Opco and its Subsidiaries.

4.4Replacement of CNP Guarantees. Exhibit A hereto lists certain guarantees (the “CNP Guarantees”) issued by CNP or CERC for the benefit of a member of the Opco Group as of the Closing Date. Opco and CNP shall use commercially reasonable efforts and cooperate with each other to terminate, or cause to be terminated, the CNP Guarantees and release, or cause to be released, CNP, CERC or their applicable affiliate from the CNP Guarantees, including by causing a member of the Opco Group to enter into a substitute guarantee for each CNP Guarantee or to assume the CNP Guarantees, in each case within 180 days following the Closing Date; provided, however, that nothing in this Section 4.4 shall obligate any Group Member to

13

provide any form of security other than a guarantee, including any letter of credit, cash collateral or security interest in any asset.

4.5Insurance.

(a)At Opco's request, each of CNP and OGE agrees to use commercially reasonable efforts to assert and diligently pursue all rights to insurance coverage under the CNP Midstream Insurance Policies and Enogex Insurance Policies and any other past insurance policies of each of CNP and OGE relating to the business or the assets of the CNP Midstream Entities or the Enogex Entities (such insurance policies collectively referred to herein as the “Insurance Policies”) with respect to insured claims asserted prior to the Closing and any such claims asserted following the Closing that are covered under an applicable Insurance Policy (collectively, the “Assumed Claims”). Each of CNP and OGE shall remit to Opco all insurance proceeds obtained after Closing with respect to the Assumed Claims. Furthermore, each of CNP and OGE agrees to use commercially reasonable efforts to negotiate with each of its respective insurance companies in order to provide Opco the benefit of the coverage under the policies for all claims asserted on or after the Closing Date and to cooperate with Opco with any efforts to obtain “tail” coverage, at Opco's sole cost, with respect to any “claims made policies.” Notwithstanding anything herein to the contrary, (i) any recovery of insurance proceeds by Opco shall be net of all cost and expenses of CNP and OGE, respectively, and (ii) any deductibles or self-insured retentions paid by CNP or OGE under applicable Insurance Policies that are recovered by an insurer (whether under any right of subrogation or otherwise) shall be for the benefit of CNP, OGE or their respective Affiliates, to the extent such party paid such deductible or self-insured retention, and shall not be retained by Opco. Each of CNP and OGE shall give Opco access to all of the non-privileged information relating to these matters and shall consult with Opco on the progress thereof from time to time.

(b)After the Closing, Opco shall be responsible for, and neither CNP, OGE nor any of their respective Affiliates shall have any responsibility for, the payment of any deductible amounts or underlying limits attributable to the Insurance Policies to the extent related to the Assumed Claims. Opco acknowledges that certain of the Insurance Policies may require CNP or OGE or any of their respective Affiliates to provide an indemnity to the insurance carrier for deductible amounts and to provide collateral to secure such indemnity obligations. Opco shall enter into an indemnification agreement in form mutually acceptable to Opco, CNP and OGE wherein Opco agrees to indemnify and hold harmless each of CNP and OGE or any of their respective Affiliates (as applicable) for any and all of the costs of maintaining such collateral and for any charges made against such collateral or indemnification payments in connection with claims arising or alleged to arise from the operations of the business of the CNP Midstream Entities or the Enogex Entities required to be paid by CNP or OGE of any of their respective Affiliates (as applicable) under or with respect to such Insurance Policies from and after the Closing Date.

(c)Neither CNP nor OGE makes any representation or warranty with respect to the applicability, validity or adequacy of any Insurance Policies, and neither CNP nor OGE shall be responsible to Opco or any member of the Opco Group for the failure of any insurer to pay under such Insurance Policy.

14

(d)Nothing in this Agreement is intended to provide or shall be construed as providing a benefit or release to any insurer or claims service organization of any obligation under any Insurance Policy. Nothing herein shall be construed as creating or permitting any insurer or claims service organization the right of subrogation against CNP, OGE, Opco or any of their respective Affiliates in respect of payments made by one to the other under any Insurance Policy.

ARTICLE V

MISCELLANEOUS

5.1Governing Law; Jurisdiction; Waiver of Jury Trial. To the maximum extent permitted by applicable Law, the provisions of this Agreement shall be governed by and construed and enforced in accordance with the Laws of the State of Delaware, without regard to principles of conflict of laws. Each of the Parties hereto agrees that this Agreement involves at least $100,000 and that this Agreement has been entered into in express reliance upon 6 Del. C. § 2708. Each of the Parties hereto irrevocably and unconditionally confirms and agrees (a) that it is and shall continue to be subject to the jurisdiction of the courts of the State of Delaware and of the federal courts sitting in the State of Delaware and (b)(i) to the extent that such Party is not otherwise subject to service of process in the State of Delaware, to appoint and maintain an agent in the State of Delaware as such Party's agent for acceptance of legal process and notify the other Parties hereto of the name and address of such agent and (ii) to the fullest extent permitted by Law, that service of process may also be made on such Party by prepaid certified mail with a proof of mailing receipt validated by the U.S. Postal Service constituting evidence of valid service, and that, to the fullest extent permitted by applicable Law, service made pursuant to (b)(i) or (ii) above shall have the same legal force and effect as if served upon such Party personally within the State of Delaware. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, EACH PARTY HERETO HEREBY IRREVOCABLY AND UNCONDITIONALLY (A) CONSENTS AND SUBMITS TO THE EXCLUSIVE JURISDICTION OF ANY FEDERAL OR STATE COURT LOCATED IN THE STATE OF DELAWARE, INCLUDING THE DELAWARE COURT OF CHANCERY IN AND FOR NEW CASTLE COUNTY (THE “DELAWARE COURTS”) FOR ANY ACTIONS, SUITS OR PROCEEDINGS ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT (AND AGREES NOT TO COMMENCE ANY LITIGATION RELATING THERETO EXCEPT IN SUCH COURTS), (B) WAIVES ANY OBJECTION TO THE LAYING OF VENUE OF ANY SUCH LITIGATION IN THE DELAWARE COURTS AND AGREES NOT TO PLEAD OR CLAIM IN ANY DELAWARE COURT THAT SUCH LITIGATION BROUGHT THEREIN HAS BEEN BROUGHT IN ANY INCONVENIENT FORUM AND (C) ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY THAT MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT.

5.3Entire Agreement. This Agreement constitutes the entire agreement of the Parties relating to the matters contained herein, superseding all prior contracts or agreements, whether oral or written, relating to the matters contained herein.

17

5.4Amendment or Modification. This Agreement may be amended or modified from time to time only by the written agreement of all the Parties hereto. Each such instrument shall be reduced to writing.

5.5Assignment. No Party shall have the right to assign any of its rights or obligations under this Agreement without the consent of the other Parties hereto; provided, however, that Bronco may assign all of its rights and obligations under this Agreement to a Bronco Successor (as defined in the Partnership Agreement) that is not a Midstream Successor (as defined in the Partnership Agreement) and upon such assignment, Bronco shall no longer be entitled to exercise any of such rights and obligations under this Agreement; providedfurther that any assignment by Bronco to a Bronco Successor shall not relieve Bronco of its obligations under Section 4.2 of this Agreement.

5.6Counterparts. This Agreement may be executed in any number of counterparts with the same effect as if all signatory parties had signed the same document. All counterparts shall be construed together and shall constitute one and the same instrument.

5.7Severability. If any provision of this Agreement shall be held invalid or unenforceable by a court or regulatory body of competent jurisdiction, the remainder of this Agreement shall remain in full force and effect.

5.8Further Assurances. In connection with this Agreement and all transactions contemplated by this Agreement, each signatory party hereto agrees to execute and deliver such additional documents and instruments and to perform such additional acts as may be necessary or appropriate to effectuate, carry out and perform all of the terms, provisions and conditions of this Agreement and all such transactions.

5.9Specific Performance. Damages in the event of breach of this Agreement by a Party may be difficult, if not impossible, to ascertain, and it is therefore agreed that each such Party, in addition to and without limiting any other remedy or right it may have, will have the right to an injunction or other equitable relief in any court of competent jurisdiction, enjoining any such breach, and enforcing specifically the terms and provisions hereof, and each of the Parties hereby waives any and all defenses it may have on the ground of lack of jurisdiction or competence of the court to grant such an injunction or other equitable relief. The existence of this right will not preclude any such Party from pursuing any other rights and remedies at law or in equity which such Party may have.

5.10Enforcement; Rights of Limited Partners after IPO Closing Date. The provisions of this Agreement are enforceable solely by the Parties to this Agreement; provided, however, that (a) the provisions of Section 3.1 are enforceable only by the Sponsor Parties and (b) if the IPO Closing Date occurs, no limited partner of Opco shall have the right, separate and apart from Opco, to enforce any provision of this Agreement or to compel any Party to this Agreement to comply with the terms of this Agreement.

5.11Successors. This Agreement shall bind and inure to the benefit of the Parties and to their respective successors and assigns.

Each payment delivered to the Agent for the account of any Lender shall be delivered promptly by the Agent to such Lender in the same type of funds that the Agent received at such Lender's address specified pursuant to Section 9.20 or at any Lending Installation specified in a notice received by the Agent from such Lender.

- 30 -

maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Obligations in accordance with their terms.

(d)Any Lender may request that its Loans be evidenced by a promissory note in substantially the form of Exhibit B (a “Note”). In such event, the Borrower shall prepare, execute and deliver to such Lender such Note payable to such Lender.

Section 2.14.Telephonic Notices. The Borrower hereby authorizes the Lenders and the Agent to extend, convert or continue Advances, effect selections of Types of Advances and to transfer funds based on telephonic notices (confirmed promptly in writing) made by any person or persons the Agent or any Lender in good faith believes to be acting on behalf of the Borrower. The Borrower agrees to deliver promptly to the Agent a written confirmation of each telephonic notice, signed by an Authorized Officer.

All other computations of interest shall be calculated for actual days elapsed on the basis of a 360-day year. Interest shall be payable for the day an Advance is made but not for the day of any payment on the amount paid if payment is received prior to noon at the place of payment. If any payment of principal of or interest on an Advance or any other amounts payable to the Agent or any Lender hereunder shall become due on a day which is not a Business Day, such payment shall be made on the next succeeding Business Day and, in the case of a principal payment, such extension of time shall be included in computing interest in connection with such payment.

Section 2.18.Non‑Receipt of Funds by the Agent. Unless the Borrower notifies the Agent prior to the time which it is scheduled to make payment to the Agent of a payment of principal or interest to the Agent for the account of the Lenders, that it does not intend to make such payment, the Agent may assume that such payment has been made. The Agent may, but shall not be obligated to, make the amount of such payment available to the intended recipient in reliance upon such assumption.

(d)in the case of any such assignment resulting from (i) a claim for compensation under Section 3.1 or payments required to be made pursuant to Section 3.5, such assignment will result in a reduction in such compensation or payments thereafter or (ii) a suspension under Section 3.3, such assignment shall be made to a Lender or Eligible Assignee which is not subject to such a suspension; and

(e)such assignment does not conflict with Applicable Law.

A Lender shall not be required to make any such assignment if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment cease to apply.

If the Borrower and the Agent agree in writing that a Lender is no longer a Defaulting Lender, the Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein, such Lender will, to the extent applicable, purchase at par that portion of outstanding Loans of the other Lenders and/or take such other actions as the Agent may determine to be necessary to cause the Loans to be held by the Lenders in accordance with their respective Pro Rata Shares, whereupon such Lender will cease to be a Defaulting Lender (and the Pro Rata Shares of each Lender will automatically be adjusted on a prospective basis to reflect the foregoing); provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrower while that Lender was a Defaulting Lender; and provided, further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Non-Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender's having been a Defaulting Lender.

Section 2.25.Obligations of Lenders.

(a)Funding by Lenders; Presumption by the Agent. Unless the Agent shall have received notice from a Lender prior to the proposed time of any borrowing that such Lender will not make available to the Agent such Lender's share of such Advance, the Agent may assume that such Lender has made such share available on such date in accordance with the

- 34 -

terms hereof and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable borrowing available to the Agent, then the applicable Lender and the Borrower severally agree to pay to the Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Agent, at (i) in the case of a payment to be made by such Lender, the greater of the daily average Federal Funds Effective Rate and a rate determined by the Agent in accordance with banking industry rules on interbank compensation and (ii) in the case of a payment to be made by the Borrower, the interest rate applicable to such Loans. If the Borrower and such Lender shall pay such interest to the Agent for the same or an overlapping period, the Agent shall promptly remit to the Borrower the amount of such interest paid by the Borrower for such period. If such Lender pays its share of the applicable Advance to the Agent, then the amount so paid shall constitute such Lender's Loan included in such borrowing. Any payment by the Borrower shall be without prejudice to any claim the Borrower may have against a Lender that shall have failed to make such payment to the Agent.

(b)Nature of Obligations of Lenders Regarding Extensions of Credit. The obligations of the Lenders under this Agreement to make the Loans are several and are not joint or joint and several. The failure of any Lender to make available its Pro Rata Share of any Advance requested by the Borrower shall not relieve it or any other Lender of its obligation, if any, hereunder to make its Pro Rata Share of such Advance available on the Closing Date, but no Lender shall be responsible for the failure of any other Lender to make its Pro Rata Share of such Advance available on the Closing Date.

ARTICLE III.

YIELD PROTECTION; TAXES

Section 3.1.Yield Protection.

(a)Increased Costs Generally. If any Change in Law shall:

(i)impose, modify or deem applicable any reserve, special deposit, compulsory loan or similar requirement against assets of, deposits with or for the account of, or credit extended or participated in by, any Lender;

(ii)subject any Recipient to any Taxes (other than (A) Indemnified Taxes, (B) Taxes described in clauses (b) through (d) of the definition of Excluded Taxes and (C) Other Connection Taxes) on its loans, loan principal, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto; or

(iii)impose on any Lender or the London interbank market any other condition, cost or expense (other than Taxes) affecting this Agreement or Loans made by such Lender;

and the result of any of the foregoing shall be to increase the cost to the Agent or such other Recipient of making, converting into, continuing or maintaining any Loan (or of maintaining its

- 35 -

obligation to make any such Loan), or to reduce the amount of any sum received or receivable by such Recipient hereunder (whether of principal, interest or any other amount) then, upon written request of such Recipient, the Borrower shall promptly pay to such Recipient such additional amount or amounts as will compensate such Recipient for such additional costs incurred or reduction suffered; provided that the Borrower shall not be required to pay any such amounts to any Recipient under and pursuant to this Section which are owing as a result of any Specified Change if and to the extent such Recipient is not at such time generally assessing such costs in a similar manner to other similarly situated borrowers with similar credit facilities.

(b)Capital Requirements. If any Lender determines that any Change in Law affecting such Lender or any Lending Installation of such Lender or such Lender's holding company, if any, regarding capital or liquidity requirements, has or would have the effect of reducing the rate of return on such Lender's capital or on the capital of such Lender's holding company, if any, as a consequence of this Agreement, the Commitment of such Lender or the Loan made by such Lender, to a level below that which such Lender or such Lender's holding company could have achieved but for such Change in Law (taking into consideration such Lender's policies and the policies of such Lender's holding company with respect to capital adequacy and liquidity), then from time to time the Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender or such Lender's holding company for any such reduction suffered; provided that the Borrower shall not be required to pay any such amounts to any Lender under and pursuant to this Section which are owing as a result of any Specified Change if and to the extent such Lender is not at such time generally assessing such costs in a similar manner to other similarly situated borrowers with similar credit facilities.

(c)Delay in Requests. Failure or delay on the part of any Lender to demand compensation pursuant to this Section shall not constitute a waiver of such Lender's right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender pursuant to this Section for any increased costs incurred or reductions suffered more than ninety (90) days prior to the date that such Lender notifies the Borrower of the Change in Law giving rise to such increased costs or reductions, and of such Lender's intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the ninety-day period referred to above shall be extended to include the period of retroactive effect thereof).

Section 3.2.Changed Circumstances Affecting Eurodollar Rate Availability. In connection with any request for a Eurodollar Advance or a Base Rate Advance or a conversion to or continuation thereof, if for any reason (a) the Agent shall determine (which determination shall be conclusive and binding absent manifest error) that Dollar deposits are not being offered to banks in the London interbank Eurodollar market for the applicable amount and Interest Period of such Advance, (b) the Agent shall determine (which determination shall be conclusive and binding absent manifest error) that reasonable and adequate means do not exist for ascertaining the Eurodollar Rate for such Advance or (c) the Required Lenders shall determine (which determination shall be conclusive and binding absent manifest error) that the Eurodollar Rate does not adequately and fairly reflect the cost to such Lenders of making or maintaining such Advance during such Interest Period, then the Agent shall promptly give notice thereof to the Borrower and the other Lenders. Thereafter, until the Agent notifies the Borrower and the

- 36 -

other Lenders that such circumstances no longer exist, (i) the obligation of the Lenders to make Eurodollar Advances and the right of the Borrower to convert any Advance to or continue any Advance as a Eurodollar Advance shall be suspended, and the Borrower shall, at the Borrower's option, either (A) repay in full (or cause to be repaid in full) the then outstanding principal amount of each such Eurodollar Advance together with accrued interest thereon (subject to Section 2.15), on the last day of the then current Interest Period applicable to such Eurodollar Advance; or (B) convert, without premium or penalty and without liability for any amounts payable pursuant to Section 3.4, the then outstanding principal amount of each such Eurodollar Advance to a Base Rate Advance as of the last day of such Interest Period; and (ii) the Alternate Base Rate shall be calculated without giving effect to clause (c) of such definition.

Section 3.3.Laws Affecting Eurodollar Rate Availability. If, after the date hereof, the introduction of, or any change in, any Applicable Law or any change in the interpretation or administration thereof by any Governmental Authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any of the Lenders (or any of their respective Lending Installations) with any request or directive (whether or not having the force of law) of any such Governmental Authority, central bank or comparable agency, shall make it unlawful or impossible for any of the Lenders (or any of their respective Lending Installations) to honor its obligations hereunder to make or maintain any Eurodollar Advance, such Lender shall promptly give notice thereof to the Agent and the Agent shall promptly give notice to the Borrower and the other Lenders. Thereafter, until the Agent notifies the Borrower and the other Lenders that such circumstances no longer exist, (i) the obligations of the Lenders to make Eurodollar Advances, and the right of the Borrower to convert any Advance or continue any Advance as a Eurodollar Advance, shall be suspended and thereafter the Borrower may select only Base Rate Loans, (ii) if any of the Lenders may not lawfully continue to maintain a Eurodollar Advance to the end of the then current Interest Period applicable thereto, the applicable Loan shall immediately be converted to a Base Rate Loan for the remainder of such Interest Periodand (iii) the Alternate Base Rate shall be calculated without giving effect to clause (c) of such definition.

Section 3.4.Funding Indemnification. If (i) any payment of a Eurodollar Advance occurs on a date which is not the last day of the applicable Interest Period, whether because of acceleration, prepayment or otherwise, including pursuant to Section 9.19, (ii) a Eurodollar Advance is not made, continued or converted on the date specified by the Borrower in a Borrowing Notice or a Conversion/Continuation Notice for any reason other than default by the Lenders, (iii) a Eurodollar Advance is not prepaid on the date specified by the Borrower pursuant to Section 2.6 for any reason, or (iv) a Eurodollar Loan is assigned on a date which is not the last day of the applicable Interest Period as a result of a request by the Borrower pursuant to Section 2.19, then, except (a) as otherwise provided in this Agreement or (b) if arising in connection with a Lender becoming a Defaulting Lender or the replacement of such Lender pursuant to Section 2.19, for any such amounts that would be owing to such Lender, the Borrower will indemnify each Lender for any loss or cost incurred by it resulting therefrom, including any loss or cost in liquidating or employing deposits acquired to fund or maintain such Eurodollar Advance but excluding the Applicable Margin expected to be received by such Lender during the remainder of such Interest Period.

- 37 -

Section 3.5.Taxes.

(a) [Intentionally Omitted].

(b)Payments Free of Taxes. Any and all payments to a Recipient by or on account of any obligation of the Borrower or the Guarantor under any Loan Document shall be made without deduction or withholding for any Taxes, except as required by Applicable Law. If any Applicable Law (as determined in the good faith discretion of an applicable Withholding Agent) requires the deduction or withholding of any Tax from any such payment by a Withholding Agent, then the applicable Withholding Agent shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with Applicable Law and, if such Tax is an Indemnified Tax, then the sum payable by the Borrower or the Guarantor (as the case may be) shall be increased as necessary so that after such deduction or withholding has been made (including such deductions and withholdings applicable to additional sums payable under this Section) the applicable Recipient receives an amount equal to the sum it would have received had no such deduction or withholding for Indemnified Tax been made.

(c)Payment of Other Taxes by the Borrower.The Borrower shall timely pay to the relevant Governmental Authority in accordance with Applicable Law, or at the option of the Agent timely reimburse it for the payment of, any Other Taxes.

(d)Indemnification by the Borrower.The Borrower shall indemnify each Recipient, within 30 days after demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section) payable or paid by such Recipient or required to be withheld or deducted from a payment to such Recipient and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority; provided, however, the Borrower shall not be required to indemnify a Recipient pursuant to this Section 3.5(d) for any Indemnified Taxes unless such Recipient makes written demand on the Borrower for indemnification for such Indemnified Taxes no later than one hundred twenty (120) days after the earlier of (i) the date on which the relevant Governmental Authority makes written demand upon such Recipient for payment of such Indemnified Taxes, and (ii) the date on which such Recipient has made payment of such Indemnified Taxes. A certificate satisfying the requirements of Section 3.6 as to the amount of such payment or liability delivered to the Borrower by a Lender (with a copy to the Agent), or by the Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error.

(e)Indemnification by the Lenders.Each Lender shall severally indemnify the Agent, within 10 days after demand therefor, for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that the Borrower has not already indemnified the Agent for such Indemnified Taxes and without limiting the obligation of Borrower to do so), (ii) any Taxes attributable to such Lender's failure to comply with the provisions of Section 12.2 relating to the maintenance of a Participant Register and (iii) any Excluded Taxes attributable to such Lender, in each case, that are payable or paid by the Agent in connection with any Loan Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes

- 38 -

were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any Lender by the Agent shall be conclusive absent manifest error. Each Lender hereby authorizes the Agent to set off and apply any and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by the Agent to the Lender from any other source against any amount due to the Agent under this Section 3.5(e).

(f)Evidence of Payments. As soon as practicable after any payment of Taxes by the Borrower to a Governmental Authority pursuant to this Section 3.5, the Borrower shall deliver to the Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Agent.

(g)Status of Lenders.

(i)Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Loan Document shall deliver to the Borrower and the Agent, at the time or times reasonably requested by the Borrower or the Agent, such properly completed and executed documentation reasonably requested by the Borrower or the Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably requested by the Borrower or the Agent, shall deliver such other documentation prescribed by Applicable Law or reasonably requested by the Borrower or the Agent as will enable the Borrower or the Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Sections 3.5(g)(ii)(A), (ii)(B) and (ii)(D) below) shall not be required if in such applicable Lender's reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender.

(ii)Without limiting the generality of the foregoing,

(A)any Lender that is a U.S. Person shall deliver to the Borrower and the Agent on or prior to the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Agent), properly completed and executed originals of IRS Form W-9 certifying that such Lender is exempt from U.S. federal backup withholding Tax;

(B)any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Agent), whichever of the

- 39 -

following is applicable:

(1)in the case of a Foreign Lender claiming the benefits of an income Tax treaty to which the United States is a party (x) with respect to payments of interest under any Loan Document, properly completed and executed originals of IRS Form W‑8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “interest” article of such Tax treaty and (y) with respect to any other applicable payments under any Loan Document, properly completed and executed originals of IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “business profits” or “other income” article of such Tax treaty;

(2)properly completed and executed originals of IRS Form W-8ECI;

(3)in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code, (x) a certificate substantially in the form of Exhibit C-1 to the effect that such Foreign Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, a “10 percent shareholder” of the Borrower within the meaning of Section 881(c)(3)(B) of the Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code (a “U.S. Tax Compliance Certificate”) and (y) properly completed and executed originals of IRS Form W-8BEN; or

(4)to the extent a Foreign Lender is not the beneficial owner, properly completed and executed originals of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN, a U.S. Tax Compliance Certificate substantially in the form of Exhibit C-2 or C-3, IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Foreign Lender is a partnership and one or more direct or indirect partners of such Foreign Lender are claiming the portfolio interest exemption, such Foreign Lender may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit C-4 on behalf of each such direct and indirect partner;

(C)any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Agent), executed originals of any other form prescribed by Applicable Law as a basis for claiming exemption from or a reduction in U.S. federal withholding Tax, duly completed, together with such supplementary documentation as may be prescribed by Applicable Law to permit the Borrower or the Agent to determine the withholding or deduction

- 40 -

required to be made; and

(D)if a payment made to a Lender under any Loan Document would be subject to U.S. federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Borrower and the Agent at the time or times prescribed by Applicable Law and at such time or times reasonably requested by the Borrower or the Agent such documentation prescribed by Applicable Law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower or the Agent as may be necessary for the Borrower and the Agent to comply with their obligations under FATCA and to determine that such Lender has complied with such Lender's obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (D), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

(iii)To the extent the Agent is not acting as a Lender, the Agent shall comply with the requirements of this Section 3.5(g) to the same extent as if it were a Lender (whose obligations under this Section 3.5(g) shall be solely to the Borrower) since the date on which it became the Agent.

Each Lender agrees that if any form or certification it previously delivered expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the Borrower and the Agent in writing of its legal inability to do so.

(h)Treatment of Certain Refunds.If any party determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Section 3.5 (including by the payment of additional amounts pursuant to this Section 3.5), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such indemnified party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over pursuant to this Section 3.5(h) (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event that such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this Section 3.5(h), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this Section 3.5(h) the payment of which would place the indemnified party in a less favorable net after-Tax position than the indemnified party would have been in if the Tax subject to indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax had never been paid. This paragraph shall not be construed to

- 41 -

require any indemnified party to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the indemnifying party or any other Person.

(i)Survival. Each party's obligations under this Section 3.5 shall survive the resignation or replacement of the Agent or any assignment of rights by, or the replacement of, a Lender, the termination of the Commitments and the repayment, satisfaction or discharge of all obligations under any Loan Document.

(j)Applicable Law. For purposes of this Section 3.5, the term “Applicable Law” includes FATCA.

Section 3.6.Lender Statements; Survival of Indemnity. Each Lender shall deliver a written statement of such Lender to the Borrower (with a copy to the Agent) as to the amount due, if any, under Section 3.1, 3.2, 3.4 or 3.5. Such written statement shall set forth in reasonable detail the calculations upon which such Lender determined such amount and shall be final, conclusive and binding on the Borrower in the absence of manifest error. Determination of amounts payable under such Sections in connection with a Eurodollar Loan shall be calculated as though each Lender funded its Eurodollar Loan through the purchase of a deposit of the type and maturity corresponding to the deposit used as a reference in determining the Eurodollar Rate applicable to such Loan, whether in fact that is the case or not. Unless otherwise provided herein, the amount specified in the written statement of any Lender shall (unless the subject of a good faith dispute by the Borrower) be payable within fifteen (15) days after demand and receipt by the Borrower of such written statement. The obligations of the Borrower under Sections 3.1, 3.2, 3.4 and 3.5 shall survive payment of the Obligations and termination of this Agreement.

Section 3.7.Alternative Lending Installation. If any Lender requests compensation under Section 3.1, or the Borrower is required to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 3.5, or is unable to fund or maintain Eurodollar Advances or Eurodollar Loans, as applicable, as a result of the circumstances described in Section 3.3, then such Lender shall (at the request of the Borrower) use reasonable efforts to designate a different Lending Installation for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 3.1 or 3.5 or remedy the circumstances described in Section 3.3, as the case may be, in the future, and (ii) would not in the reasonable judgment of such Lender subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. A Lender shall not be required to make any such designation or assignment if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances requiring such designation or assignment cease to apply. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment, if and to the extent such Lender is at such time generally assessing such costs and expenses in a similar manner to other similarly situated borrowers with similar credit facilities.

ARTICLE V.

REPRESENTATIONS AND WARRANTIES

The Borrower represents and warrants to the Lenders that:

Section 5.1.Existence and Standing. Each of the Borrower and its Material Subsidiaries is a corporation, partnership or limited liability company duly incorporated or organized, as the case may be, validly existing and in good standing under the laws of its jurisdiction of incorporation or organization and has all requisite authority to conduct its business in each jurisdiction where the conduct of its business would require such qualification, except where the failure to be in good standing or have such authority could not reasonably be expected to have a Material Adverse Effect.

Section 5.2.Authorization and Validity; Enforceability. The Borrower has the power and authority and legal right to execute and deliver the Loan Documents to which it is a party (as in effect on the date that this representation is made or deemed made) and to perform its obligations thereunder. This Agreement and each other Loan Document to which the Borrower is a party have been duly executed and delivered on behalf of the Borrower. The execution and delivery by the Borrower of the Loan Documents to which it is a party (as in effect on the date that this representation is made or deemed made) and the performance of its obligations thereunder have been duly authorized by proper limited partnership or other applicable actions, and the Loan Documents to which it is party constitute legal, valid and binding obligations of the Borrower enforceable against the Borrower in accordance with their terms, except as enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors' rights generally and by general principles of equity (whether enforcement is sought at equity or in law).

Section 5.3.No Conflict. Neither the execution and delivery by the Borrower of the Loan Documents to which it is a party, nor the performance by the Borrower of its obligations thereunder, nor the consummation of the Transactions will (a) violate the Borrower's or any Material Subsidiary's articles or certificate of incorporation, partnership agreement, certificate of partnership, articles or certificate of organization, bylaws, or operating or other management

- 45 -

No course of dealing between the Borrower, the Agent and the Lenders or their respective agents or employees shall be effective to change, modify or discharge any provision of this Agreement or any of the other Loan Documents or to constitute a waiver of any Event of Default.

(b)Defaulting Lenders. Anything herein to the contrary notwithstanding, during such period as a Lender is a Defaulting Lender, to the fullest extent permitted by

- 64 -

Applicable Law, such Lender will not be entitled to vote in respect of amendments and waivers hereunder and the Commitment and the outstanding Loans or other extensions of credit of such Lender hereunder will not be taken into account in determining whether the Required Lenders or all of the Lenders, as required, have approved any such amendment or waiver (and the definition of “Required Lenders” will automatically be deemed modified accordingly for the duration of such period); provided, that any such amendment or waiver that would increase or extend the term of the Commitment of such Defaulting Lender, extend the date fixed for the payment of principal or interest owing to such Defaulting Lender hereunder, reduce the principal amount of any obligation owing to such Defaulting Lender, reduce the amount of or the rate or amount of interest on any amount owing to such Defaulting Lender or of any fee payable to such Defaulting Lender hereunder, or alter the terms of this proviso, will require the consent of such Defaulting Lender.

The respective obligations of the Lenders hereunder are several and not joint and no Lender shall be the partner or agent of any other (except to the extent to which the Agent is authorized to act as such).

This Agreement shall not be construed so as to confer any right or benefit upon any Person other than the parties to this Agreement and their respective successors and assigns; provided, that the parties hereto expressly agree that each Arranger shall enjoy the benefits of the provisions of Sections 9.7, 9.11 and 10.9 to the extent specifically set forth therein and shall have the right to enforce such provisions on its own behalf and in its own name to the same extent as if it were a party to this Agreement.

In the case of an investigation, litigation or other proceeding to which the indemnity in this Section 9.7(b) applies, such indemnity will be effective whether or not such investigation, litigation or proceeding is brought by the Borrower, any of its directors, security holders or creditors, an Indemnitee or any other person or an Indemnitee is otherwise a party thereto and whether or not the transactions contemplated by this Agreement are consummated. The obligations of the Borrower under this Section 9.7(b) shall survive the termination of this Agreement. In no event shall this clause (b) operate to expand the obligations of the Borrower under the first sentence of clause (a) above to require the Borrower to reimburse or indemnify the Lenders, the Syndication Agent or the Co-Documentation Agents

- 66 -

for any amounts of the type described therein. This Section 9.7(b) shall not apply with respect to Taxes other than any Taxes that represent losses, claims, damages, etc. arising from any non-Tax claim.

Each party hereto agrees that no other party hereto nor any of its Related Parties shall have any liability to any other party hereto (or its Related Parties) on any theory of liability for any special, indirect, consequential or punitive damages (including without limitation, any loss of profits, business or anticipated savings) in connection with, arising out of, or in any way related to the Loan Documents or the transactions contemplated thereby; provided that this waiver shall in no way limit the Borrower's indemnification obligations in Section 9.7(b) to the extent of any third-party claim for any of the foregoing, including the Borrower's obligation to indemnify Indemnitees for special, indirect, consequential or punitive damages awarded against an Indemnitee.

Section 9.13.Lenders Not Utilizing Plan Assets. Each Lender represents and warrants that none of the consideration used by such Lender to make its Loans constitutes for any purpose of ERISA or Section 4975 of the Code assets of any “plan” as defined in Section 3(3) of ERISA or Section 4975 of the Code and the rights and interests of such Lender in and under the Loan Documents shall not constitute such “plan assets” under ERISA.

- 69 -

Each notice by the Borrower under this Section 9.19 shall constitute a representation by the Borrower that the removal described in such notice is permitted under this Section 9.19. Concurrently with such removal and as a condition thereof, the Borrower shall pay to such removed Lender (or, if such Lender is a Defaulting Lender, to Agent) all amounts owing to such Lender hereunder (including any amounts arising under Section 3.4 as a consequence of such removal) and under any other Loan Document in immediately available funds.

ARTICLE X.

THE AGENT

Section 10.1.Appointment and Authority. Each of the Lenders hereby irrevocably designates and appoints Citibank to act on its behalf as the Agent hereunder and under the other Loan Documents and authorizes the Agent to take such actions on its behalf and to exercise such powers as are delegated to the Agent by the terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto. The provisions of this Article are solely for the benefit of the Agent and the Lenders, and neither the Borrower nor any Subsidiary thereof shall have rights as a third party beneficiary of any of such provisions. It is understood and agreed that the use of the term “agent” herein or in any other Loan Documents (or any other similar term) with reference to the Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead such term is used as a matter of market custom, and is intended to create or reflect only an administrative relationship between contracting parties.

Section 10.2.Rights as a Lender. The Person serving as the Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Agent and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, own securities of, act as the financial advisor or in any other advisory capacity for, and generally engage in any kind of business with, the Borrower or any Subsidiary or other Affiliate thereof as if such Person were not the Agent hereunder and without any duty to account therefor to the Lenders.

Section 10.3.Exculpatory Provisions. The Agent shall not have any duties or obligations except those expressly set forth herein and in the other Loan Documents, and its duties hereunder shall be administrative in nature. Without limiting the generality of the foregoing, the Agent:

(a)shall not be subject to any fiduciary or other implied duties, regardless of whether an Event of Default has occurred and is continuing;

(b)shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that the Agent is required to exercise as directed in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be expressly provided for herein or in the other Loan Documents); provided that the Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Agent to liability or that is contrary to any Loan Document or Applicable Law, including for the avoidance of doubt, any action that may be in violation of the automatic stay under any Debtor Relief Law or that may effect a forfeiture, modification or termination of property of a Defaulting Lender in violation of any Debtor Relief Law; and

- 71 -

(c)shall not, except as expressly set forth herein and in the other Loan Documents, haveany duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower or any of its Affiliates that is communicated to or obtained by the Person serving as the Agent or any of its Affiliates in any capacity.

The Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary, or as the Agent shall believe in good faith shall be necessary, under the circumstances as provided in Section 9.1) or (ii) in the absence of its own gross negligence, bad faith or willful misconduct as determined by a court of competent jurisdiction by a final and nonappealable judgment. The Agent shall be deemed not to have knowledge of any Default or Event of Default unless and until notice describing such Default or Event of Default is given to the Agent in writing by the Borrower or a Lender.

The Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default or Event of Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document or (v) the satisfaction of any condition set forth in Article IV or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Agent.

Section 10.4.Reliance by the Agent. The Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, Internet or intranet website posting or other distribution) reasonably believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. The Agent also may rely upon any statement made to it orally or by telephone and reasonably believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of a Loan that by its terms must be fulfilled to the satisfaction of a Lender, the Agent may presume that such condition is satisfactory to such Lender unless the Agent shall have received notice to the contrary from such Lender prior to the making of such Loan. The Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

Section 10.5.Delegation of Duties. The Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Loan Document by or through any one or more sub-agents selected and appointed by the Agent. The Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties. The exculpatory provisions of this Article shall apply to any such sub-agent and to the Related Parties of the Agent and any such sub agent, and shall apply to their respective activities in connection with the syndication of the credit facility evidenced hereby as

- 72 -

well as activities as Agent. The Agent shall not be responsible for the negligence or misconduct of any sub-agents except to the extent that a court of competent jurisdiction determines in a final and nonappealable judgment that the Agent acted with gross negligence, bad faith or willful misconduct in the selection of such sub-agents.

Section 10.6.Resignation of Agent.

(a)The Agent may at any time give notice of its resignation to the Lenders and the Borrower. Upon receipt of any such notice of resignation, the Required Lenders shall have the right, in consultation with the Borrower (and so long as no Event of Default shall have occurred and be continuing, subject to the approval of the Borrower, such approval not to be unreasonably withheld or delayed), to appoint a successor from among the Lenders, which shall be a bank with an office in the United States having capital and retained earnings of at least $100,000,000, or an Affiliate of any such bank with an office in the United States. If no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Agent gives notice of its resignation (or such earlier day as shall be agreed by the Required Lenders) (the “Resignation Effective Date”), then the retiring Agent may (but shall not be obligated to), on behalf of the Lenders, appoint a successor Agent meeting the qualifications set forth above; provided that if the Agent shall notify the Borrower and the Lenders that no qualifying Person has accepted such appointment, then all payments, communications and determinations provided to be made by, to or through the Agent shall instead be made by or to each Lender directly, until such time as the Required Lenders appoint a successor Agent as provided for above in this paragraph (with the approval of the Borrower to the extent required above). Whether or not a successor has been appointed, such resignation of the retiring Agent shall become effective in accordance with such notice on the Resignation Effective Date.

(b)With effect from the Resignation Effective Date (1) the retiring Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents and (2) except for any indemnity payments owed to the retiring Agent, all payments, communications and determinations provided to be made by, to or through the Agent shall instead be made by or to each Lender directly, until such time, if any, as the Required Lenders appoint a successor Agent as provided for above. Upon the acceptance of a successor's appointment as Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring or retired Agent (other than any rights to indemnity payments owed to the retiring Agent), and the retiring Agent shall be discharged from all of its duties and obligations hereunder or under the other Loan Documents. The fees payable by the Borrower to a successor Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the retiring Agent's resignation hereunder and under the other Loan Documents, the provisions of this Article X and Section 9.7 shall continue in effect for the benefit of such retiring Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring Agent was acting as Agent. In the event that there is a successor to the Agent by merger, or the Agent assigns its duties and obligations to an Affiliate pursuant to this Section 10.6, then the term “Prime Rate” as used in this Agreement shall mean the prime rate, base rate or other analogous rate of the new Agent.

- 73 -

Section 10.7.Non-Reliance on Agent and Other Lenders. Each Lender acknowledges that it has, independently and without reliance upon the Agent or any other Lender or any of their Related Parties and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Agent or any other Lender or any of their Related Parties and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document or any related agreement or any document furnished hereunder or thereunder.

Section 10.8.No Other Duties, etc. Anything herein to the contrary notwithstanding, none of the Syndication Agent, the Co-Documentation Agents, or the Arrangers listed on the cover page or signature pages hereof shall have any powers, duties or responsibilities under this Agreement or any of the other Loan Documents, except in its capacity, as applicable, as the Agent or a Lender hereunder.

Section 10.9.Agent, Arrangers and Co-Documentation Agent Fees. The Borrower agrees to pay to the Agent, each Arranger and each Co-Documentation Agent, for their respective accounts, the fees agreed to by the Borrower pursuant to the applicable Fee Letters.

Section 10.10.Agent's Reimbursement and Indemnification. The Lenders agree to reimburse and indemnify the Agent, the Syndication Agent, the Arrangers and the Co-Documentation Agents ratably in proportion to the Lenders' Pro Rata Shares of the Aggregate Commitment (or, if the Aggregate Commitment has been terminated, of the Outstanding Credit Exposure) for any amounts not reimbursed by the Borrower (a) for which the Agent, the Syndication Agent, any Arranger or any Co-Documentation Agent is entitled to reimbursement by the Borrower under the Loan Documents, (b) for any other expenses incurred by the Agent, the Syndication Agent, any Arranger or any Co-Documentation Agent on behalf of the Lenders, in connection with the preparation, execution, delivery, administration and enforcement of the Loan Documents and (b) for any liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind and nature whatsoever which may be imposed on, incurred by or asserted against the Agent, the Syndication Agent, any Arranger or any Co-Documentation Agent in any way relating to or arising out of the Loan Documents or any other document delivered in connection therewith or the transactions contemplated thereby (including for any such amounts incurred by or asserted against the Agent, the Syndication Agent, any Arranger or any Co-Documentation Agent in connection with any dispute between the Agent, the Syndication Agent, any Arranger any Co-Documentation Agent and any Lender or between two or more of the Lenders), or the enforcement of any of the terms of the Loan Documents or of any such other documents (collectively, the “Indemnified Costs”); provided that (i) no Lender shall be liable for any portion of the Indemnified Costs that are found in a final non-appealable judgment by a court of competent jurisdiction to have resulted from the gross negligence, bad faith or willful misconduct of the party seeking indemnification and (ii) any indemnification required pursuant to Section 3.4 shall, notwithstanding the provisions of this Section 10.9, be paid by the relevant Lender in accordance with the provisions thereof. The failure of any Lender to reimburse the Agent, the Syndication Agent, any Arranger or any Co-Documentation Agent, as the case may be, promptly upon demand for its Pro Rata Share of any

- 74 -

amount required to be paid by the Lenders as provided herein shall not relieve any other Lender of its obligation hereunder to reimburse the Agent, the Syndication Agent, any Arranger or any Co-Documentation Agent, as the case may be, for its Pro Rata Share of such amount, but no Lender shall be responsible for the failure of any other Lender to reimburse such Agent, Syndication Agent, Arranger or Co-Documentation Agent, as the case may be, for such other Lender's Pro Rata Share of such amount. The obligations of the Lenders under this Section 10.9 shall survive payment of the Obligations and termination of this Agreement.

Section 10.11.Agent May File Proofs of Claim. In case of the pendency of any proceeding under any Debtor Relief Law, the Lenders hereby agree that the Agent (irrespective of whether the principal of any Loan shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Agent shall have made any demand on the Borrower) shall be entitled and empowered (but not obligated) by intervention in such proceeding or otherwise for and on behalf of the Lenders:

(a)to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans and all other Obligations that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Lenders and the Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders and the Agent and their respective agents and counsel and all other amounts due the Lenders and the Agent under Section 9.7) allowed in such judicial proceeding; and

(b)to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender to make such payments to the Agent and, in the event that the Agent shall consent to the making of such payments directly to the Lenders, to pay to the Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Agent and its agents and counsel, and any other amounts due the Agent under Section 9.7.

Section 10.12.Trust Indenture Act. In the event that Citibank or any of its Affiliates shall be or become an indenture trustee under the Trust Indenture Act of 1939 (as amended, the “Trust Indenture Act”) in respect of any securities issued or guaranteed by the Borrower or any of its Subsidiaries, the parties hereto acknowledge and agree that any payment or property received in satisfaction of or in respect of any Obligation of the Borrower or any of its Subsidiaries hereunder or under any other Loan Document by or on behalf of Citibank in its capacity as the Agent for the benefit of any Lender under any Loan Document (other than Citibank or an Affiliate of Citibank) and which is applied in accordance with the Loan Documents shall be deemed to be exempt from the requirements of Section 311 of the Trust Indenture Act pursuant to Section 311(b)(3) of the Trust Indenture Act.

ARTICLE XI.

SETOFF; RATABLE PAYMENTS

Section 11.1.Setoff. In addition to, and without limitation of, any rights of the Lenders under Applicable Law, from and after the date that the Obligations have been accelerated pursuant to Section 8.2(a) or Section 8.2(b) (and for so long as such acceleration has not been rescinded by the Required Lenders), each Lender and each of its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by Applicable Law, to set-off and apply any and all deposits (including all account balances, whether general or special, time or demand, provisional or final and whether or not collected or available) at any time held, and any other Indebtedness or obligations (in whatever currency) at any time held or owing, by such Lender or any such Affiliate, to or for the credit or account of the Borrower against any and all of the Obligations of the Borrower now or hereafter existing under this Agreement or any other Loan Document to such Lender or its Affiliates, irrespective of whether or not such Lender or Affiliate shall have made any demand under this Agreement or any other Loan Document and although such Obligations of the Borrower may be contingent or unmatured or are owed to a branch, office or Affiliate of such Lender different from the branch, office or Affiliate holding such deposit or obligated on such indebtedness; provided that in the event that any Defaulting Lender exercises any such right of setoff, (x) all amounts so set off shall be paid over immediately to the Agent for further application in accordance with the provisions of Section 2.24 and, pending such payment, shall be segregated by such Defaulting Lender from its other funds and deemed held in trust for the benefit of the Agent and the Lenders, and (y) the Defaulting Lender shall provide promptly to the Agent a statement describing in reasonable detail the Obligations owing to such Defaulting Lender as to which it exercised such right of setoff. The rights of each Lender and its Affiliates under this Section are in addition to other rights and remedies (including other rights of setoff) that such Lender or its Affiliates may have. Each Lender agrees to notify the Borrower and the Agent promptly after any such setoff and application; provided that the failure to give such notice shall not affect the validity of such setoff and application.

Section 11.2.Ratable Payments. If any Lender, whether by setoff or otherwise, has payment made to it upon its Outstanding Credit Exposure (other than payments received pursuant to Section 3.1, 3.2, 3.4 or 3.5) in a greater proportion than that received by any other Lender, such Lender agrees, promptly upon demand, to purchase a portion of the Aggregate Outstanding Credit Exposure held by the other Lenders so that after such purchase each Lender will hold its Pro Rata Share of the Aggregate Outstanding Credit Exposure. If any Lender, whether in connection with setoff or amounts which might be subject to setoff or otherwise, receives collateral or other protection for its Obligations or such amounts which may be subject to setoff, such Lender agrees, promptly upon demand, to take such action necessary such that all Lenders share in the benefits of such collateral ratably in proportion to their respective Pro Rata Shares of the Aggregate Outstanding Credit Exposure. In case any such payment is disturbed by legal process, or otherwise, appropriate further adjustments shall be made.

ARTICLE XII.

BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS

Section 12.1.Successors and Assigns. The terms and provisions of the Loan Documents shall be binding upon and inure to the benefit of the Borrower, the Agent and the Lenders and their respective successors and assigns permitted hereby, except that (a) the Borrower shall not have the right to assign its rights or obligations under the Loan Documents without the prior written consent of each Lender, (b) any assignment by any Lender must be made in compliance with Section 12.3, and (c) any transfer by participation must be made in compliance with Section 12.2. Any attempted assignment or transfer by any party not made in compliance with this Section 12.1 shall be null and void, unless such attempted assignment or transfer is treated as a participation in accordance with Section 12.3(c). The parties to this Agreement acknowledge that clause (b) of this Section 12.1 relates only to absolute assignments and this Section 12.1 does not prohibit assignments creating security interests, including any pledge or assignment by any Lender of all or any portion of its rights under this Agreement and any Note to a Federal Reserve Bank or any central bank having jurisdiction over such Lender; provided that no such pledge or assignment creating a security interest shall release the transferor Lender from its obligations hereunder unless and until the parties thereto have complied with the provisions of Section 12.3. The Agent may treat each Lender which made the Credit Extension hereunder or which holds any Note as the owner thereof for all purposes hereof unless and until such Lender complies with Section 12.3; provided that the Agent may in its discretion (but shall not be required to) follow instructions from the Lender which made the Credit Extension hereunder or which holds any Note to direct payments relating to such Credit Extension or Note to another Person. Any assignee of the rights to the Credit Extension or any Note agrees by acceptance of such assignment to be bound by all the terms and provisions of the Loan Documents. Any request, authority or consent of any Lender, who at the time of making such request or giving such authority or consent is the owner of the rights to the Credit Extension (whether or not a Note has been issued in evidence thereof), shall be conclusive and binding on any subsequent holder or assignee of the rights to such Credit Extension.

Section 12.2.Participations.

(a)Permitted Participants; Effect. Any Lender may at any time, without the consent of, or notice to, the Borrower or the Agent, sell participations to any Person (other than a natural Person, the Borrower or any of the Borrower's Affiliates or Subsidiaries or, unless an Event ofDefault has occurred and is continuing, (x) any competitor of the Borrower or any of its Subsidiaries or (y) any other company engaged in the business of selling or distributing energy products; provided that this clause (y) shall not apply to any financial institution solely as a result of such Person trading in commodity products) (each, a “Participant”) in all or a portion of such Lender's rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Loans owing to it); provided that (i) such Lender's obligations under this Agreement and the other Loan Documents, if any, shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) such Lender shall remain the owner of its Outstanding Credit Exposure and the holder of any Note issued to it in evidence thereof for all purposes under the Loan Documents and all amounts

- 77 -

payable by the Borrower under this Agreement shall be determined as if such Lender had not sold such participating interest and (iv) the Borrower, the Agent and Lenders shall continue to deal solely and directly with such Lender in connection with such Lender's rights and obligations under this Agreement. For the avoidance of doubt, each Lender shall be responsible for the indemnity under Section 10.10 with respect to any payments made by such Lender to its Participant(s).

(b)Voting Rights. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve, without the consent of any Participant, any amendment, modification or waiver of any provision of this Agreement other than any amendment, modification or waiver with respect to the Credit Extension or Commitment in which such Participant has an interest which would require consent of all of the Lenders or all of the affected Lenders pursuant to the terms of Section 9.1.

(c)Benefit of Certain Provisions. The Borrower further agrees that each Participant shall be entitled to the benefits of Sections 3.1, 3.2, 3.4 and 3.5 (subject to the requirements and limitations therein, including the requirements under Section 3.5(g) (it being understood that the documentation required under Section 3.5(g) shall be delivered to the participating Lender)) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to Section 12.3; provided that such Participant (i) agrees to be subject to the provisions of Sections 2.19 and 3.7 as if it were an assignee under Section 12.3; and (ii) shall not be entitled to receive any greater payment under Section 3.1 or 3.5, with respect to any participation, than its participating Lender would have been entitled to receive, except to the extent such entitlement to receive a greater payment results from a Change in Law that occurs after the Participant acquired the applicable participation. Each Lender that sells a participation agrees, at the Borrower's request and expense, to use commercially reasonable efforts to require such Participant comply with the provisions of Sections 2.19 and 3.7 as if it were a Lender and to cooperate with the Borrower in enforcing such provisions against such Participant. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 11.1 as though it were a Lender; provided that such Participant agrees to be subject to Section 11.2 as though it were a Lender.

(d)Participant Register. Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant's interest in the Loans or other obligations under the Loan Documents (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant's interest in any commitments, loans or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such commitment, loan or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this

- 78 -

Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Agent (in its capacity as Agent) shall have no responsibility for maintaining a Participant Register.

Section 12.3.Assignments.

(a)Permitted Assignments. Any Lender may at any time assign to one or more Eligible Assignees (such an assignee, a “Purchaser”) all or any part of its rights and obligations under the Loan Documents. The parties to each assignment shall execute and deliver to the Agent an Assignment and Assumption Agreement. Each such assignment with respect to an Eligible Assignee which is not a Lender or an Affiliate of a Lender or an Approved Fund shall either be in an amount equal to the entire applicable Commitment and Outstanding Credit Exposure of the assigning Lender or (unless each of the Borrower and the Agent otherwise consents) be in an aggregate amount not less than $5,000,000. The amount of the assignment shall be based on the Commitment or Outstanding Credit Exposure (if the Commitment has been terminated) subject to the assignment, determined as of the date of such assignment or as of the “Trade Date,” if the “Trade Date” is specified in the assignment. Each partial assignment made by a Lender shall be made as an assignment of a proportionate part of all of such Lender's rights and obligations under this Agreement with respect to the Loans and Commitments assigned.

(b)Consents. The consent of the Agent (such consent not to be unreasonably withheld or delayed) shall be required prior to an assignment becoming effective; provided that the consent of the Agent shall not be required for any assignment to a Person that is a Lender, an Affiliate of such Lender or an Approved Fund with respect to such Lender. The consent of the Borrower (such consent not to be unreasonably withheld or delayed) shall be required prior to an assignment becoming effective unless (i) such assignment is to a Lender, an Affiliate of a Lender or an Approved Fund or (ii) an Event of Default has occurred and is continuing; provided that the Borrower shall be deemed to have consented to any such assignment unless it shall object thereto by written notice to the Agent within fifteen (15) days after having received notice thereof. Any consent required under this Section 12.3(b) shall not be unreasonably withheld or delayed.

(c)Effect; Effective Date. Subject to acceptance and recording of the assignment by the Agent pursuant to Section 12.3(d), upon (i) delivery to the Agent of an Assignment and Assumption Agreement pursuant to Section 12.3(a), together with any consents required by Section 12.3(b), (ii) payment by the parties to the Assignment and Assumption Agreement (other than the Borrower) of a $3,500 fee to the Agent for processing such assignment (unless such fee is waived by the Agent) and (iii) delivery to the Borrower and the Agent of the documents required by Section 3.5, such Assignment and Assumption Agreement shall become effective on the effective date specified in such Assignment and Assumption Agreement. The Assignment and Assumption Agreement shall contain a representation and warranty by the Purchaser to the effect that none of the funds, money, assets or other consideration used to make the purchase and assumption of the Commitment and Outstanding Credit Exposure under the applicable assignment agreement constitutes “plan assets” as defined under ERISA and that the rights, benefits and interests of the Purchaser in and under the Loan Documents will not be “plan assets” under ERISA. On and after the effective date of such assignment, such Purchaser shall for all purposes be a Lender party to this Agreement and any

- 79 -

other Loan Document executed by or on behalf of the Lenders and shall have all the rights, benefits and obligations of a Lender under the Loan Documents, to the same extent as if it were an original party thereto, and the transferor Lender shall be released with respect to the Commitment and Outstanding Credit Exposure assigned to such Purchaser without any further consent or action by the Borrower, the Lenders or the Agent. In the case of an assignment covering all of the assigning Lender's rights, benefits and obligations under this Agreement, such Lender shall cease to be a Lender hereunder but shall continue to be entitled to the benefits of, and subject to, those provisions of this Agreement and the other Loan Documents which survive payment of the Obligations and termination of the Loan Documents with respect to facts and circumstances occurring prior to the effective date of such assignment; provided that no assignment by a Defaulting Lender will constitute or effect a waiver or release of any claim of any party arising from such Lender being a Defaulting Lender. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 12.3 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with Section 12.2. Upon the consummation of any assignment to a Purchaser pursuant to this Section 12.3(c), the transferor Lender, the Agent and the Borrower shall, if the transferor Lender or the Purchaser desires that its Loans be evidenced by Notes, make appropriate arrangements so that, upon cancellation and surrender to the Borrower of the Notes (if any) held by the transferor Lender, new Notes or, as appropriate, replacement Notes are issued to such transferor Lender, if applicable, and new Notes or, as appropriate, replacement Notes, are issued to such Purchaser, in each case in principal amounts reflecting their respective Commitments (or if the Aggregate Commitment has been terminated, their respective Outstanding Credit Exposure), as adjusted pursuant to such assignment.

(d)Register. The Agent, acting solely for this purpose as a non-fiduciary agent of the Borrower (and the Borrower hereby designates the Agent to act in such capacity), shall maintain at one of its offices in the United States a copy of each Assignment and Assumption Agreement delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amounts (and stated interest) of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, absent manifest error, and the Borrower, the Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(e)No Assignment to Certain Persons. No such assignment shall be made to (i) the Borrower or any of the Borrower's Affiliates or Subsidiaries, (ii) any Defaulting Lender or any of its Subsidiaries, or any Person who, upon becoming a Lender hereunder, would constitute any of the foregoing Persons described in this clause (ii) or (iii) unless an Event of Default has occurred and is continuing, (x) any competitor of the Borrower or any of its Subsidiaries or (y) any other company engaged in the business of selling or distributing energy products; provided that this clause (y) shall not apply to any financial institution solely as a result of such Person trading in commodity products.

- 80 -

(f)No Assignment to Natural Persons. No such assignment shall be made to a natural Person.

(g)Certain Additional Payments. In connection with any assignment of rights and obligations of any Defaulting Lender hereunder, no such assignment shall be effective unless and until, in addition to the other conditions thereto set forth herein, the parties to the assignment make such additional payments to the Agent in an aggregate amount sufficient, upon distribution thereof as appropriate (which may be outright payment, purchases by the assignee of participations or subparticipations, or other compensating actions, including funding, with the consent of the Borrower and the Agent, the applicable Pro Rata Share of Loans previously requested but not funded by the Defaulting Lender, to each of which the applicable assignee and assignor hereby irrevocably consent), to (x) pay and satisfy in full all payment liabilities then owed by such Defaulting Lender to the Agent and each Lender hereunder (and interest accrued thereon), and (y) acquire (and fund as appropriate) its full pro rata share of all Loans in accordance with its Pro Rata Share. Notwithstanding the foregoing, in the event that any assignment of rights and obligations of any Defaulting Lender hereunder becomes effective under Applicable Law without compliance with the provisions of this paragraph, then the assignee of such interest shall be deemed to be a Defaulting Lender for all purposes of this Agreement until such compliance occurs.

Section 12.4.Dissemination of Information. The Borrower authorizes each Lender to disclose to any Participant or Purchaser or any other Person acquiring an interest in the Loan Documents by operation of law (each a “Transferee”) and any prospective Transferee any and all information in such Lender's possession concerning the creditworthiness of the Borrower and its Subsidiaries; provided that each Transferee and prospective Transferee agrees to be bound by Section 9.12.

Section 12.5.Tax Certifications. If any interest in any Loan Document is transferred to any Transferee which is not incorporated under the laws of the United States or any State thereof, the transferor Lender shall cause such Transferee, concurrently with the effectiveness of such transfer, to comply with the provisions of Section 3.5.

Section 12.6.No Liability of General Partner. It is hereby understood and agreed that the General Partner shall have no personal liability, as general partner or otherwise, for the payment of any amount owing or to be owing hereunder or under the other Loan Documents. The Agent and the Lenders agree for themselves and their respective successors and assigns that no claim arising against the Borrower or the Guarantor under any Loan Document with respect to the Obligations shall be asserted against the General Partner (in its individual capacity).

NOTHING HEREIN SHALL LIMIT THE RIGHT OF THE AGENT OR ANY LENDER TO BRING PROCEEDINGS AGAINST THE BORROWER IN THE COURTS OF ANY OTHER JURISDICTION.

Notwithstanding the foregoing, (i) if the Designated Ratings are split and all three ratings fall in different levels, the Applicable Margin shall be based upon the level indicated by the middle rating; (ii) if the Designated Ratings are split and two of the ratings fall in the same level (the “Majority Level”) and the third rating is in a different level, the Applicable Margin shall be based

upon the Majority Level; (iii) if only two of the three Rating Agencies issue a Designated Rating, the higher of such ratings shall apply, provided that if the higher rating is two or more levels above the lower rating, the rating next below the higher of the two shall apply; (iv) if only one of the three Rating Agencies issues a Designated Rating, such rating shall apply; and (v) if the Designated Rating established by S&P, Moody's or Fitch shall be changed (other than as a result of a change in the rating system of S&P, Moody's or Fitch), such change shall be effective as of the date on which it is first announced by the applicable Rating Agency. If the rating system of S&P, Moody's or Fitch shall change, or if any of S&P, Moody's or Fitch shall cease to be in the business of rating corporate debt obligations, the Borrower and the Agent shall negotiate in good faith if necessary to amend this provision to reflect such changed rating system or the unavailability of Designated Ratings from such Rating Agencies and, pending the effectiveness of any such amendment, the Applicable Margin for Eurodollar Rate Advances and the Applicable Margin for Base Rate Advances shall be determined by reference to the Designated Rating of such Rating Agency most recently in effect prior to such change or cessation.

Section 2.4.Types of Advances. The Advances (other than any Swing Line Loan) may be Base Rate Advances or Eurodollar Advances, or a combination thereof, selected by the Borrower in accordance with Sections 2.8 and 2.9. The Borrower may request Swing Line Loans in accordance with Section 2.23.

Section 2.5.Commitment Fee; Reductions in Aggregate Commitment.

(a)Commitment Fee. The Borrower agrees to pay to the Agent for the account of each Lender (subject, with respect to any Defaulting Lender, to the limitations set forth in Section 2.24(a)(iii)) a commitment fee (the “Commitment Fee”) at a per annum rate equal to the Applicable Fee Rate on such Lender's unused Commitment (it being understood that Swing Line Loans (to the extent participations therein have not been funded by the Lenders pursuant to Section 2.23(d)(ii)) will not be deemed a utilization of the Commitments solely for purposes of this Section) from the Closing Date to the Revolving Credit Maturity Date applicable thereto, payable on each Payment Date and the Revolving Credit Maturity Date; provided that, if any Lender continues to have Loans outstanding hereunder after the Revolving Credit Maturity Date, then the Commitment Fee shall continue to accrue on the aggregate principal amount of the Loans owed to such Lender until the date on which such Loans are repaid in full.

(b)Reductions in Aggregate Commitment. The Borrower may without premium or penalty permanently reduce the Aggregate Commitment in whole, or in part, ratably among the Lenders in a minimum amount of $10,000,000 or any integral multiple of $1,000,000 in excess thereof, upon at least three (3) Business Days' written notice to the Agent, which notice shall specify the amount of any such reduction; provided that the amount of the Aggregate Commitment may not be reduced below the aggregate principal amount of the outstanding Advances, after taking into account any prepayments to be made on or before such date.

Section 2.6.Minimum Amount of Each Advance. Each Eurodollar Advance shall be in the minimum amount of $5,000,000 (and in multiples of $1,000,000 if in excess thereof), and each Base Rate Advance (other than an Advance to repay Swing Line Loans) shall be in the minimum amount of $1,000,000 (and in multiples of $500,000 if in excess thereof); provided, that any Base Rate Advance may be in the amount of the unused Aggregate Commitment.

- 25 -

Section 2.7.Prepayments.

(a)Optional Prepayments. The Borrower may from time to time prepay, without penalty or premium, all outstanding Base Rate Advances, or any portion thereof in a minimum aggregate amount of $1,000,000 or any integral multiple of $500,000 in excess thereof, on any Business Day upon notice to the Agent by no later than 11:00 a.m. on the date of such prepayment. The Borrower may at any time prepay, without penalty or premium, all outstanding Swing Line Loans, or any portion thereof, on any Business Day upon notice to the Agent and the Swing Line Lender by 11:00 a.m. on the date of such repayment. The Borrower may from time to time prepay, subject to the payment of any amounts required by Section 3.4 but without penalty or premium, all outstanding Eurodollar Advances, or any portion thereof in a minimum aggregate amount of $5,000,000 or any integral multiple of $1,000,000 in excess thereof upon at least two (2) Business Days' prior notice to the Agent (or such shorter period as may be acceptable to the Agent). Subject to the terms and conditions hereof, the Borrower may borrow, repay and reborrow Revolving Loans and Swing Line Loans hereunder until the Revolving Credit Maturity Date. Each prepayment of the Loans under this Section 2.7 shall be applied as specified by the Borrower; and each such prepayment shall be paid to the Lenders in accordance with their respective Pro Rata Shares or, in the case of Swing Line Loans, to the Swing Line Lender.

(b)Mandatory Prepayments. If, on any Business Day, the Aggregate Outstanding Credit Exposures exceed the Aggregate Commitment (an “Excess”), then the Borrower shall, within two (2) Business Days after the earlier of (i) the Borrower's receipt of written notice of an Excess from the Agent and (ii) the date any Authorized Officer has actual knowledge of such Excess, solely to the extent of such Excess: first, prepay to the Swing Line Lender the outstanding principal amount of the Swing Line Loans; second, if any Excess shall remain, prepay to the Agent, for the ratable account of each of the Lenders, in whole or in part, a principal amount of Revolving Loans comprising part of the same Borrowing(s) selected by the Borrower; and third, if any Excess shall remain, Cash Collateralize the Facility LCs in an amount that will eliminate such Excess.

Section 2.8.Method of Selecting Types and Interest Periods for New Advances (other than Swing Line Loans). The Borrower shall select the Type of Advance (other than any Swing Line Loan which is subject to Section 2.23) and, in the case of each Eurodollar Advance, the Interest Period applicable thereto from time to time. The Borrower shall give the Agent irrevocable notice (a “Borrowing Notice”) in accordance with Section 2.14, which, when in writing, shall be in substantially the form attached hereto as Exhibit G, not later than 11:00 a.m. on the Borrowing Date of each Base Rate Advance and by 11:00 a.m. three (3) Business Days before the Borrowing Date for each Eurodollar Advance to be made on such Borrowing Date (or, in the case of any Eurodollar Advance to be made on the Closing Date, by 11:00 a.m. two (2) Business Days before the Closing Date), in each case, specifying:

(a)the Borrowing Date, which shall be a Business Day, of such Advance;

(b)the aggregate amount of such Advance;

(c)the Type of Advance selected; and

(d)in the case of a Eurodollar Advance, the Interest Period applicable thereto.

Not later than 1:00 p.m. on each Borrowing Date, each Lender (subject to the satisfaction of the applicable conditions precedent set forth in Article IV) shall make available its Revolving Loan or Revolving Loans in funds immediately available to the Agent at its address specified pursuant to Section 9.20. The Agent will

- 26 -

promptly make the funds so received from the Lenders available to the Borrower at the Agent's aforesaid address. If the Borrower requests a Eurodollar Advance but fails to specify an Interest Period therefor, such Eurodollar Advance will be deemed to have an Interest Period of one month.

Section 2.9.Conversion and Continuation of Outstanding Advances. Base Rate Advances shall continue as Base Rate Advances unless and until such Base Rate Advances are converted into Eurodollar Advances pursuant to this Section 2.9 or are repaid in accordance with Section 2.7. Each Eurodollar Advance shall continue as a Eurodollar Advance until the end of the then applicable Interest Period therefor, at which time such Eurodollar Advance shall be automatically converted into a Base Rate Advance unless (x) such Eurodollar Advance is or was repaid in accordance with Section 2.7 or (y) the Borrower shall have given the Agent a Conversion/Continuation Notice requesting that, at the end of such Interest Period, such Eurodollar Advance continue as a Eurodollar Advance for the same or another Interest Period. Subject to the terms of Section 2.6, the Borrower may elect from time to time to convert all or any part of a Base Rate Advance into a Eurodollar Advance. The Borrower shall give the Agent irrevocable notice (a “Conversion/Continuation Notice”) in accordance with Section 2.14, which, when in writing, shall be in substantially the form attached hereto as Exhibit H, of each conversion of a Base Rate Advance into a Eurodollar Advance or continuation of a Eurodollar Advance not later than 11:00 a.m. on the third Business Day prior to the date of the requested conversion or continuation, specifying:

(a)the requested date, which shall be a Business Day, of such conversion or continuation;

(b)the aggregate amount and Type of the Advance which is to be converted or continued; and

(c)the duration of the Interest Period applicable thereto.

If the Borrower requests a conversion to, or continuation of a Eurodollar Advance but fails to specify an Interest Period therefor, such Eurodollar Advance will be deemed to have an Interest Period of one month. After giving effect to all Advances, all conversions of Advances from one Type to the other, and all continuations of Advances as the same Type, there shall not be more than ten Interest Periods in effect.

Section 2.10.Changes in Interest Rate, etc. Each Base Rate Advance shall bear interest on the outstanding principal amount thereof, for each day from and including the date such Advance is made or is automatically converted from a Eurodollar Advance into a Base Rate Advance pursuant to Section 2.9, to but excluding the date it is paid or is converted into a Eurodollar Advance pursuant to Section 2.9, at a rate per annum equal to the Base Rate for such day. Each Swing Line Loan shall bear interest on the outstanding principal amount thereof, for each day from and including the day such Swing Line Loan is made to but excluding the date it is paid, at a rate per annum equal to the Swing Line Rate for such day. Changes in the rate of interest on that portion of any Advance maintained as a Base Rate Advance or on a Swing Line Loan will take effect simultaneously with each change in the Alternate Base Rate or Eurodollar Rate, respectively. Each Eurodollar Advance shall bear interest on the outstanding principal amount thereof from and including the first day of the Interest Period applicable thereto to (but not including) the last day of such Interest Period at the Eurodollar Rate for such Interest Period, as determined by the Agent. No Interest Period may end after the Scheduled Revolving Credit Maturity Date. The Borrower shall select Interest Periods so that it is not necessary to repay any portion of a Eurodollar Advance prior to the last day of the applicable Interest Period in order to make a mandatory prepayment required pursuant to the last sentence of Section 2.2.

Section 2.11.Rates Applicable After Event of Default. Notwithstanding anything to the contrary contained in Section2.8, 2.9 or 2.10, upon the occurrence and during the continuance of an Event of Default,

- 27 -

the Required Lenders may, at their option, by notice to the Borrower, declare that no Advance may be made as, converted into or continued as a Eurodollar Advance. If all or a portion of (a) the principal amount of any Loan or any Reimbursement Obligation, (b) any interest payable thereon, or (c) any fee or other amount payable hereunder shall not be paid when due (whether at the stated maturity, by acceleration or otherwise), such overdue amount shall bear interest, payable from time to time on demand, at a rate per annum equal to the Default Rate, in each case from the date of such non-payment until such amount is paid in full.

Section 2.12.Method of Payment. All payments of the Obligations hereunder shall be made, without setoff or counterclaim, in immediately available funds to the Agent at the Agent's address specified pursuant to Section 9.20, or at any other Lending Installation of the Agent specified in writing by the Agent to the Borrower, by noon on the date when due and shall be applied ratably (except in the case of (a) Reimbursement Obligations for which an LC Issuer has not been fully indemnified by the Lenders, (b) Swing Line Loans or (c) as otherwise specifically required hereunder) by the Agent among the Lenders. Each payment delivered to the Agent for the account of any Lender shall be delivered promptly by the Agent to such Lender in the same type of funds that the Agent received at such Lender's address specified pursuant to Section 9.20 or at any Lending Installation specified in a notice received by the Agent from such Lender.

Section 2.13.Noteless Agreement; Evidence of Indebtedness.

(a)Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to such Lender resulting from each Loan made by such Lender from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder.

(b)The Agent shall also maintain accounts in which it will record (i) the amount of each Loan made hereunder, the Type thereof and the Interest Period (in the case of a Eurodollar Advance) with respect thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder, (iii) the original face amount of each Facility LC and the amount of LC Obligations outstanding at any time, and (iv) the amount of any sum received by the Agent hereunder from the Borrower and each Lender's share thereof.

(c)The entries maintained in the accounts maintained pursuant to paragraphs (a) and (b) above shall be prima facie evidence of the existence and amounts of the Obligations therein recorded absent manifest error; provided, that the failure of the Agent or any Lender to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Obligations in accordance with their terms.

(d)Any Lender may request that its Loans be evidenced by a promissory note, or in the case of the Swing Line Lender, promissory notes representing its Revolving Loans and Swing Line Loans, respectively, in substantially the form of Exhibit D with applicable changes for notes evidencing Swing Line Loans (a “Note”). In such event, the Borrower shall prepare, execute and deliver to such Lender such Note payable to such Lender. Thereafter, the Loans evidenced by such Note and interest thereon shall at all times (prior to any assignment pursuant to Section 12.3) be represented by one or more Notes payable to the payee named therein, except to the extent that any such Lender subsequently returns any such Note for cancellation and requests that such Loans once again be evidenced as described in paragraphs (a) and (b) above.

Section 2.14.Telephonic Notices. The Borrower hereby authorizes the Lenders and the Agent to extend, convert or continue Advances, effect selections of Types of Advances and to transfer funds based on telephonic notices (confirmed promptly in writing) made by any person or persons the Agent or any Lender

- 28 -

in good faith believes to be acting on behalf of the Borrower. The Borrower agrees to deliver promptly to the Agent a written confirmation of each telephonic notice, signed by an Authorized Officer. If the written confirmation differs in any material respect from the action taken by the Agent and the Lenders, the records of the Agent and the Lenders shall govern absent manifest error.

Section 2.15.Interest Payment Dates; Interest and Fee Basis. Interest accrued on each Base Rate Advance and Swing Line Loan shall be payable in arrears on each Payment Date, commencing with the first such date to occur after the Closing Date, on any date on which the Base Rate Advance or Swing Line Loan is prepaid, whether due to acceleration or otherwise, and at maturity. Interest accrued on each Eurodollar Advance shall be payable on the last day of its applicable Interest Period, on any date on which the Eurodollar Advance is prepaid, whether by acceleration or otherwise, and at maturity. Interest accrued on each Eurodollar Advance having an Interest Period longer than three months shall also be payable on the last day of each three-month interval during such Interest Period. Interest on Base Rate Advances when the Alternate Base Rate is determined by the Prime Rate shall be calculated for actual days elapsed on the basis of a 365, or when appropriate 366, day year. All other computations of interest, LC Fees and all other fees shall be calculated for actual days elapsed on the basis of a 360-day year. Interest shall be payable for the day an Advance is made but not for the day of any payment on the amount paid if payment is received prior to noon at the place of payment. If any payment of principal of or interest on an Advance, any fees or any other amounts payable to the Agent or any Lender hereunder shall become due on a day which is not a Business Day, such payment shall be made on the next succeeding Business Day and, in the case of a principal payment, such extension of time shall be included in computing interest and fees in connection with such payment.

Section 2.16.Notification of Advances, Interest Rates, Prepayments and Commitment Reductions. Promptly after receipt thereof, the Agent will notify each Lender of the contents of each Aggregate Commitment reduction notice, Borrowing Notice, Swing Line Borrowing Notice, Conversion/Continuation Notice, and prepayment notice received by it hereunder. The applicable LC Issuer shall notify the Agent promptly after the issuance of a Facility LC, and the Agent will notify each Lender of such issuance. The Agent will notify the Borrower and each Lender of the interest rate applicable to each Eurodollar Advance promptly upon determination of such interest rate and will give the Borrower and each Lender prompt notice of each change in the Alternate Base Rate.

Section 2.17.Lending Installations. Each Lender may book its Loans and its participation in any LC Obligations and Swing Line Loans, and each LC Issuer may book its Facility LCs, at any Lending Installation selected by such Lender or LC Issuer, as applicable, and may change its Lending Installation from time to time. All terms of this Agreement shall apply to any such Lending Installation and the Loans, Facility LCs, participations in LC Obligations and Swing Line Loans and any Notes issued hereunder shall be deemed held by each Lender or LC Issuer, as applicable, for the benefit of any such Lending Installation. Each Lender and LC Issuer may, by written notice to the Agent and the Borrower in accordance with Section 9.20, designate replacement or additional Lending Installations through which Loans will be made by it or Facility LCs will be issued by it and for whose account Loan payments or payments with respect to Facility LCs are to be made.

Section 2.18.Non‑Receipt of Funds by the Agent. Unless the Borrower notifies the Agent prior to the time which it is scheduled to make payment to the Agent of a payment of principal, interest or fees to the Agent for the account of the Lenders, that it does not intend to make such payment, the Agent may assume that such payment has been made. The Agent may, but shall not be obligated to, make the amount of such payment available to the intended recipient in reliance upon such assumption. If the Borrower has not in fact made such payment to the Agent, the recipient of such payment shall, on demand by the Agent, repay to the Agent the amount so made available together with interest thereon in respect of each day during the

- 29 -

period commencing on the date such amount was so made available by the Agent until the date the Agent recovers such amount at a rate per annum equal to the interest rate applicable to the relevant Loan.

Section 2.19.Replacement of Lender. If (w) any Lender requests compensation under Section 3.1, or if the Borrower is required to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 3.5 and, in each case, such Lender has declined or is unable to promptly designate a different Lending Installation in accordance with Section 3.7 which would eliminate any further claims for such indemnity, compensation or payment, (x) any Lender is a Defaulting Lender or a Non-Consenting Lender, (y) any Lender's obligation to make or to convert or continue outstanding Loans or Advances as Eurodollar Loans or Eurodollar Advances has been suspended pursuant to Section 3.3, and, in each such case, such Lender has declined or is unable to promptly designate a different Lending Installation in accordance with Section 3.7 which would eliminate any further suspension or (z) in addition to the rights of the Borrower under Section 2.21, any Lender is a Non-Extending Lender and the Required Lenders have approved the related Extension Request, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Agent, require such Lender to assign and delegate (provided that the failure by any such Lender that is a Defaulting Lender to execute an Assignment and Assumption Agreement shall not render such assignment invalid), without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 12.3), all of its interests, rights (other than its existing rights to payments pursuant to Section 3.1 or 3.5) and obligations under this Agreement and the related Loan Documents (other than, if such Lender is an LC Issuer that has issued any outstanding Facility LCs at such time, its rights and obligations as an LC Issuer with respect to such Facility LCs) to an Eligible Assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that:

(a)the Borrower shall have received (i) the prior written consent of the Agent, the Swing Line Lender, and each LC Issuer with respect to any assignee that is not already a Lender or an affiliate of a Lender hereunder, which consent shall not unreasonably be withheld, conditioned or delayed, (ii) the consent of such assignee to the assignment, (iii) in the case of any assignment resulting from a Lender becoming a Non-Consenting Lender, the consent of the applicable assignee to the applicable amendment, waiver or consent and (iv) in the case of an assignment resulting from a Lender becoming a Non-Extending Lender, the consent of the applicable assignee to the applicable Extension Request;

(b)the Agent shall have received the assignment fee specified in Section 12.3(c) unless (i) waived by the Agent or (ii) the assignee is another Lender;

(c)such Lender shall have received payment of an amount equal to its funded and outstanding principal balance of its Outstanding Credit Exposure, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents (including (other than with respect to any Defaulting Lender) any amounts under Section 3.4) from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts);

(d)in the case of any such assignment resulting from (i) a claim for compensation under Section 3.1 or payments required to be made pursuant to Section 3.5, such assignment will result in a reduction in such compensation or payments thereafter or (ii) a suspension under Section 3.3, such assignment shall be made to a Lender or Eligible Assignee which is not subject to such a suspension; and

(e)such assignment does not conflict with Applicable Law.

- 30 -

A Lender shall not be required to make any such assignment if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment cease to apply.

Section 2.20.Facility LCs.

(a)Issuance. Each LC Issuer hereby agrees, on the terms and conditions set forth in this Agreement, to issue standby letters of credit for any lawful purpose (each such letter of credit, a “Facility LC”) denominated in Dollars and to renew, extend, increase, decrease or otherwise modify each Facility LC (“Modify,” and each such action, a “Modification”), from time to time from and including the Closing Date and prior to the Revolving Credit Maturity Date upon the request of the Borrower; providedthat immediately after each such Facility LC is issued or Modified, (i) the LC Obligations shall not exceed the LC Commitment, (ii) the Aggregate Outstanding Credit Exposure shall not exceed the Aggregate Commitment and (iii) the aggregate amount of LC Obligations of any LC Issuer at any time shall not exceed such LC Issuer's LC Issuer Sublimit, unless otherwise expressly agreed by such LC Issuer. On the Closing Date, the letter of credit heretofore issued by Bank of America, N.A. described on Schedule 1.1 shall automatically, and without any further action by any party, constitute a Facility LC issued pursuant to this Section 2.20, and Bank of America, N.A., solely for the purpose of maintaining such letter of credit, shall constitute an LC Issuer for so long as (and only for so long as) such letter of credit remains outstanding.

(b)Expiration of Facility LCs. In the event that the expiry date of a Facility LC is later than five (5) Business Days prior to the Scheduled Revolving Credit Maturity Date, prior to such date that is five (5) Business Days prior to the Scheduled Revolving Credit Maturity Date, the Borrower shall deliver to the Agent cash, to be held by the Agent, for the benefit of the LC Issuers and the Lenders, in the Cash Collateral Account as security for the LC Obligations in respect of subsequent drawings under such Facility LC in an amount equal to 100% of the face amount of such outstanding Facility LC plus related fees and expenses with respect to such outstanding Facility LC over its remaining term (which cash will be invested pursuant to the requirements of Section 2.20(j)), pursuant to documentation in form and substance reasonably satisfactory to the Agent and the applicable LC Issuer. Any Facility LC with a one-year tenor may provide for the renewal thereof for additional one-year periods. If any Facility LC contains a provision pursuant to which it is deemed to be automatically renewed unless notice of termination is given by the applicable LC Issuer with respect to such Facility LC, such LC Issuer shall timely give notice of termination if (A) as of the close of business on the seventeenth (17^th) day prior to the last day upon which such LC Issuer's notice of termination may be given to the beneficiaries of such Facility LC, such LC Issuer has received a notice of termination from the Borrower or a notice from the Agent that the conditions to issuance of such Facility LC have not been satisfied or (B) the renewed Facility LC would extend beyond the date that is five (5) Business Days prior to the Scheduled Revolving Credit Maturity Date (unless such Facility LC is Cash Collateralized per the terms of this Section 2.20(b)).

(c)Participations. Upon (i) the issuance by the applicable LC Issuer of each Facility LC in accordance with this Section 2.20 and (ii) the Modification of each Facility LC increasing or decreasing the face amount thereof in accordance with this Section 2.20, the applicable LC Issuer shall be deemed, without further action by any party hereto, to have unconditionally and irrevocably sold to each Lender, and each Lender shall be deemed, without further action by any party hereto, to have unconditionally and irrevocably purchased from such LC Issuer, a participation in such Facility LC (and each Modification thereof) and the related LC Obligations in proportion to such Lender's Pro Rata Share.

(d)Procedures for Issuing or Modifying a Facility LC. Subject to Section 2.20(a) and (b), (i) to request the issuance of a Facility LC, the Borrower shall deliver an LC Application to the applicable LC Issuer prior to 11:00 a.m. at least three (3) Business Days prior to the proposed date of issuance thereof

- 31 -

and (ii) to request a Modification of a Facility LC, the Borrower shall deliver notice thereof to the applicable LC Issuer prior to 11:00 a.m. at least three (3) Business Days prior to the proposed date of Modification, identifying the Facility LC to be Modified and specifying the name and address of the beneficiary, the proposed date of Modification, the expiry date of such Modified Facility LC and such other information as shall be reasonably requested by such LC Issuer to Modify such Facility LC, accompanied by the written consent of the beneficiary thereto to the extent such consent is required pursuant to the terms of such Facility LC. Upon the applicable LC Issuer's receipt of an LC Application or a notice of Modification, such LC Issuer shall promptly notify the Agent, and, in the case of an issuance of a Facility LC only, the Agent shall then promptly notify each Lender of the contents thereof and of the amount of such Lender's participation in such Facility LC. Subject to each LC Issuer's agreements set forth herein, each Facility LC issued by such LC Issuer shall be in a form reasonably satisfactory to such LC Issuer. In the event of any conflict or inconsistency between the terms of this Agreement and the terms of any LC Application or any other agreement entered into by the Borrower with an LC Issuer relating to any Facility LC, the terms of this Agreement shall control.

(e)LC Fees. The Borrower shall pay to the Agent, for the account of the Lenders (subject, with respect to any Defaulting Lender, to the limitations set forth in Section 2.24(a)(iii)) ratably in accordance with their respective Pro Rata Shares, with respect to each Facility LC, a letter of credit fee at a per annum rate equal to the Applicable Margin for Eurodollar Loans in effect from time to time on the average daily undrawn face amount under such Facility LC, such fee to be payable in arrears on each Payment Date (the “LC Participation Fee”). The Borrower shall also pay to each LC Issuer for its own account (i) a fronting fee at a per annum rate equal to 0.15% on the average daily undrawn face amount under each Facility LC issued by such LC Issuer, such fee to be payable in arrears on each Payment Date, and (ii) normal and customary charges, costs and reasonable expenses incurred or charged by such LC Issuer in connection with the issuance or Modification of and draws under the Facility LCs issued by such LC Issuer in accordance with such LC Issuer's standard schedule for such charges as in effect from time to time. Each fee described in this Section 2.20(e) shall constitute an “LC Fee”.

(f)Administration; Reimbursement by Lenders. Upon receipt from the beneficiary of any Facility LC of any demand for payment under such Facility LC, the applicable LC Issuer shall notify the Agent and the Agent shall promptly notify the Borrower and each other Lender as to the amount to be paid by the LC Issuer as a result of such demand and the proposed payment date (the “LC Payment Date”). The responsibility of each LC Issuer to the Borrower and each Lender shall be only to determine that the documents (including each demand for payment) delivered under each Facility LC in connection with such presentment shall be in strict conformity with the terms and conditions of such Facility LC. Each LC Issuer shall endeavor to exercise the same care in the issuance and administration of the Facility LCs as it does with respect to letters of credit in which no participations are granted, it being understood that each Lender shall be unconditionally and irrevocably liable without regard to the occurrence of any Event of Default or any condition precedent whatsoever, to reimburse such LC Issuer on demand without offset of any kind for (i) such Lender's Pro Rata Share of the amount of each payment made by such LC Issuer under each Facility LC with respect to any drawing or other demand for payment made by a beneficiary thereunder prior to the Scheduled Revolving Credit Maturity Date (it being understood and agreed that no Lender shall have any obligation to reimburse any LC Issuer with respect to any drawing or other demand for payment under any Facility LC made after the Scheduled Revolving Credit Maturity Date, regardless of whether the Borrower has complied with any obligation to deliver Cash Collateral in respect of such Facility LC pursuant to the terms of this Agreement), to the extent such amount is not reimbursed by the Borrower pursuant to Section 2.20(g) below, plus (ii) interest on the foregoing amount to be reimbursed by such Lender, from and including the date such payment is made by such LC Issuer to the date on which such Lender pays the amount to be

- 32 -

reimbursed by it, at a rate of interest per annum equal to the Federal Funds Effective Rate for the first three (3) days and, thereafter, at a rate of interest equal to the rate applicable to Base Rate Advances.

(g)Reimbursement by Borrower. The Borrower shall be irrevocably and unconditionally obligated to reimburse each LC Issuer on the applicable LC Payment Date (if notified of such drawing prior to 1:00 p.m. on such date, otherwise on the next Business Day following receipt of such notice) for any amounts to be paid by such LC Issuer upon any drawing under any Facility LC, without presentment, demand (other than as set forth above), protest or other formalities of any kind; provided that to the extent the Borrower does not reimburse the applicable LC Issuer on the applicable LC Payment Date (or the next Business Day, as applicable), then the Borrower shall be deemed to have requested that the Swing Line Lender make a Swing Line Loan on such date; and providedfurther that neither the Borrower nor any Lender shall hereby be precluded from asserting any claim for direct (but not consequential, special, indirect or punitive) damages suffered by the Borrower or such Lender to the extent, but only to the extent, caused by (i) such LC Issuer's gross negligence, bad faith or willful misconduct, as determined by a court of competent jurisdiction by final non-appealable judgment or (ii) such LC Issuer's failure to pay under any Facility LC issued by it after the presentation to it of a request strictly complying with the terms and conditions of such Facility LC. Each LC Issuer will pay to each Lender (other than any Defaulting Lender to the extent such Defaulting Lender has not provided Cash Collateral for the LC Issuers' Fronting Exposure in respect thereof) ratably in accordance with its Pro Rata Share all amounts received by it from the Borrower for application in payment, in whole or in part, of the Reimbursement Obligation in respect of any Facility LC issued by such LC Issuer, but only to the extent such Lender has made payment to such LC Issuer in respect of such Facility LC pursuant to Section 2.20(f). Subject to the terms and conditions of this Agreement (including the submission of a Borrowing Notice in compliance with Section 2.8 and the satisfaction of the applicable conditions precedent set forth in Article IV), the Borrower may request an Advance hereunder for the purpose of satisfying any Reimbursement Obligation.

(h)Obligations Absolute.

(i)The Borrower's obligations under this Section 2.20 shall be absolute and unconditional under any and all circumstances and irrespective of any setoff, counterclaim or defense to payment which the Borrower may have or have had against any LC Issuer, any Lender or any beneficiary of a Facility LC.

(ii)The Borrower further agrees with the LC Issuers and the Lenders that the LC Issuers and the Lenders shall not be responsible for, and the Borrower's Reimbursement Obligation in respect of any Facility LC shall not be affected by, among other things, (A) the validity or genuineness of documents, instruments or of any endorsements thereon, even if such documents should in fact prove to be in any or all respects invalid, insufficient, fraudulent or forged, (B) any dispute between or among the Borrower, any of its Affiliates, the beneficiary of any Facility LC or any financing institution or other party to whom any Facility LC may be transferred or any claims or defenses whatsoever of the Borrower or of any of its Affiliates against the beneficiary of any Facility LC or any such transferee, (C) the existence of any claims, set-off, defense or other right whatsoever of the Borrower against any beneficiary of such Facility LC or any such transferee, (D) any lack of validity or enforceability of any Facility LC or this Agreement, or any term of provision therein or herein, (E) payment by the LC Issuer under a Facility LC against presentation of a draft or other document that does not comply with the terms of such Facility LC, or (F) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section, constitute a legal or equitable discharge of, or provide a right of setoff against, the Borrower's obligations hereunder or under any Facility LC.

(iii)No LC Issuer shall be liable for any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with any Facility LC.

(iv)The Borrower agrees that any action taken or omitted by any LC Issuer or Lender under or in connection with each Facility LC and the related drafts and documents, if done without gross negligence, willful misconduct or bad faith, as determined by a final, non-appealable judgment of a court of competent jurisdiction, shall be binding upon the Borrower and shall not result in any liability of such LC Issuer or Lender to the Borrower.

(v)Nothing in this Section 2.20(h) is intended to limit the right of the Borrower to make a claim against the applicable LC Issuer for damages as contemplated by the second proviso to the first sentence of Section 2.20(g).

(i)Actions of the LC Issuers. Each LC Issuer shall be entitled to rely, and shall be fully protected in relying, upon any Facility LC, draft, writing, resolution, notice, consent, certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype message, statement, order or other document reasonably believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons, and upon advice and statements of legal counsel, independent accountants and other experts selected by such LC Issuer. In the absence of (x) willful misconduct, gross negligence or bad faith of the applicable LC Issuer (as determined by a final, non-appealable judgment of a court of competent jurisdiction) in determining whether a request presented under any Facility LC complied with the terms of such Facility LC or (y) the applicable LC Issuer's failure to pay under any Facility LC after the presentation to it of a request strictly complying with the terms and conditions of such Facility LC, such LC Issuer shall be fully (a) justified in failing or refusing to take any action under this Agreement unless it shall first have received such advice or concurrence of the Required Lenders as it reasonably deems appropriate or it shall first be indemnified to its reasonable satisfaction by the Lenders against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action, and (b) protected in acting, or in refraining from acting, under this Agreement in accordance with a request of the Required Lenders, and such request and any action taken or failure to act pursuant thereto shall be binding upon the Lenders and any future holders of a participation in any Facility LC.

(j)Cash Collateral Account.

(i)Establishment of Cash Collateral Account. If the Borrower is required to provide Cash Collateral under the terms of this Agreement, the Borrower and the Agent shall establish the Cash Collateral Account, and the Borrower shall execute any documents and agreements that the Agent reasonably requests in connection therewith to establish the Cash Collateral Account, including, if so requested, an assignment of deposit accounts in form and substance reasonably satisfactory to the Agent and the Borrower. The Borrower hereby pledges, assigns and grants to the Agent, on behalf of and for the ratable benefit of the Lenders (including the LC Issuers), and agrees to maintain, a first priority security interest in the Cash Collateral Account and all of the Borrower's right, title and interest in and to all Cash Collateral which may from time to time be on deposit in the Cash Collateral Account, and all proceeds thereof, to secure the prompt and complete payment and performance of the Obligations. If at any time the Agent determines that Cash Collateral is subject to any right or claim of any Person other than the Agent and the LC Issuers as herein provided, or that the total amount of such Cash Collateral is less than the amount required to be deposited under this Agreement, the Borrower will, promptly upon demand by the Agent, pay or provide to the Agent additional Cash

- 34 -

Collateral in an amount sufficient to eliminate such deficiency (after giving effect to any Cash Collateral provided by any Defaulting Lender).

(ii)Application of Funds. Moneys in the Cash Collateral Account held in respect of LC Obligations arising from a particular Facility LC shall be applied by the Agent to reimburse the LC Issuer that issued such Facility LC for Reimbursement Obligations that arise in connection with such Facility LC for which it has not been reimbursed and, to the extent not so applied, and subject to clause (iii) below, shall be held for the satisfaction of the reimbursement obligations of the Borrower for the Fronting Exposure with respect to such Facility LC at such time or, if the maturity of the Loans has been accelerated (but subject to the consent of the applicable LC Issuer), be applied to satisfy other Obligations of the Borrower.

(iii)Release of Funds. If no Event of Default has occurred and is continuing, within three Business Days of the Borrower's written request, the Agent shall release to the Borrower any and all funds held in the Cash Collateral Account above the aggregate amounts then expressly required, if any, to be deposited and held as Cash Collateral under all relevant provisions of this Agreement. In addition, after all of the Obligations have been paid in full (other than contingent indemnification obligations), the Aggregate Commitment has been terminated and all Facility LCs have been terminated or expired, any funds remaining in the Cash Collateral Account shall be returned by the Agent to the Borrower or paid to whomever may be legally entitled thereto at such time.

(iv)Administration of Cash Collateral Account. The Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over the Cash Collateral Account. If and when required by the Borrower, the Agent shall invest and reinvest funds held in the Cash Collateral Account from time to time in cash equivalents specified from time to time by the Borrower and reasonably acceptable to the Agent. Interest or profits, if any, on such investments shall accumulate in such account. The Agent shall exercise reasonable care in the custody and preservation of any funds held in the Cash Collateral Account and shall be deemed to have exercised such care if such funds are accorded treatment substantially equivalent to that which the Agent accords its own property, it being understood that the Agent shall not have any responsibility for taking any necessary steps to preserve rights against any parties with respect to any such funds.

(k)Rights as a Lender. In its capacity as a Lender, each LC Issuer shall have the same rights and obligations as any other Lender.

(l)Replacement of an LC Issuer. Any LC Issuer may be replaced at any time by written agreement among the Borrower, the Agent, the replaced LC Issuer and the successor LC Issuer. The Agent shall notify the Lenders of any such replacement of an LC Issuer. At the time any such replacement shall become effective, the Borrower shall pay all unpaid fees accrued for the account of the replaced LC Issuer pursuant to Section 2.20(e). From and after the effective date of any such replacement, (A) the successor LC Issuer shall have all the rights and obligations of an LC Issuer under this Agreement with respect to Facility LCs to be issued by it thereafter and (B) references herein to the term “LC Issuer” shall be deemed to refer to such successor or to any previous LC Issuer, or to such successor and all previous LC Issuers, as the context shall require. After the replacement of an LC Issuer hereunder, the replaced LC Issuer shall remain a party hereto and shall continue to have all the rights and obligations of an LC Issuer under this Agreement with respect to Facility LCs issued by it prior to such replacement, but shall not be required to issue additional Facility LCs.

- 35 -

(m)Defaulting Lenders. At any time that there shall exist a Defaulting Lender, within one (1) Business Day following the written request of the Agent or any LC Issuer (with a copy to the Agent) the Borrower shall Cash Collateralize the LC Issuers' Fronting Exposure with respect to such Defaulting Lender (determined after giving effect to the reallocation provided in Section 2.24(a)(iv) and any Cash Collateral provided by such Defaulting Lender) in an amount equal to such Fronting Exposure or such higher amount agreed to by the Borrower.

(i)Defaulting Lender's Grant of Security Interest. To the extent provided by any Defaulting Lender, such Defaulting Lender, hereby grants to the Agent, for the benefit of the LC Issuers, and agrees to maintain, a first priority security interest in all such Cash Collateral as security for such Defaulting Lender's obligation to fund participations in respect of LC Obligations, to be applied pursuant to clause (ii) below.

(ii)Application. Notwithstanding anything to the contrary contained in this Agreement, Cash Collateral provided under this Section 2.20(m) or Section 2.24 in respect of Facility LCs shall be applied to the satisfaction of the Defaulting Lender's unreallocated obligation to fund participations in respect of LC Obligations (including, as to Cash Collateral provided by a Defaulting Lender, any interest accrued on such obligation) for which the Cash Collateral was so provided, prior to any other application of such property as may otherwise be provided for herein.

(iii)Termination of Requirement. Cash Collateral (or the appropriate portion thereof) provided to reduce any LC Issuer's Fronting Exposure shall no longer be required to be held as Cash Collateral pursuant to this Section 2.20(m) following (A) the elimination of such Fronting Exposure (including by the termination of Defaulting Lender status of the applicable Lender), or (B) the determination by the Agent and each LC Issuer that there exists Cash Collateral in excess of the amount required to be maintained pursuant to the terms of this Agreement, in which case, such Cash Collateral (in the case of clause (A) above) or excess amounts (in the case of clause (B) above), as applicable, shall be returned to the Borrower upon its request therefor to the extent such Cash Collateral was provided by the Borrower; provided that, subject to Section 2.24, the Person providing Cash Collateral may agree that Cash Collateral in excess of such Fronting Exposure at any time shall be held to support future anticipated Fronting Exposure or other Obligations.

(n)Independence. The Borrower acknowledges that the rights and obligations of each LC Issuer under each Facility LC are independent of the existence, performance or nonperformance of any contract or arrangement underlying such Facility LC, including contracts or arrangements between such LC Issuer and the Borrower and between the Borrower and the beneficiary of such Facility LC.

Section 2.21.Extension of Scheduled Revolving Credit Maturity Date.

(a)Request of Extension. No later than thirty (30) days prior to the Scheduled Revolving Credit Maturity Date, the Borrower shall have the option to request (such request, an “Extension Request”) an extension of the Scheduled Revolving Credit Maturity Date for an additional one-year period; provided that no more than two (2) of such one-year extensions shall be permitted hereunder. Any election by a Lender to extend its Commitment will be at such Lender's sole discretion and such Lender's failure to respond to an Extension Request within fifteen (15) Business Days from the date of delivery of such Extension Request shall be deemed to be a refusal by such Lender to so extend its Scheduled Revolving Credit Maturity Date.

(b)Extension; Conditions Precedent. Subject to the Agent's receipt of written consents to such Extension Request from the Required Lenders (each such consenting Lender, an “Extending Lender”),

- 36 -

the Scheduled Revolving Credit Maturity Date shall be extended for an additional one-year period for each Extending Lender; provided that (i) each non-consenting Lender (together with its successors and assigns, each a “Non-Extending Lender”) shall be required only to complete its Commitment up to the previously effective Scheduled Revolving Credit Maturity Date (without giving effect to such Extension Request), (ii) the Commitment of each Extending Lender (including the Commitment of each Additional Lender (as defined below)) shall be on the same terms and conditions as the Commitment of each other Extending Lender and Additional Lender, (iii) on the date of any extension of the Scheduled Revolving Credit Maturity Date under this Section 2.21, the conditions set forth in Section 4.3 shall be satisfied and (iv) the Borrower shall deliver to the Agent a certificate dated as of the date of any extension, signed by an Authorized Officer certifying that (A) the conditions set forth in Section 4.3 shall be satisfied and (B) attaching certified copies of resolutions of the board of directors or other equivalent governing body of the General Partner approving such extension.

(c)Payments to Non-Extending Lenders; Reduction of Commitment. All Obligations and other amounts payable hereunder to each Non-Extending Lender shall become due and payable by the Borrower on the previously effective Scheduled Revolving Credit Maturity Date (without giving effect to such Extension Request) or the earlier replacement of such Non-Extending Lender pursuant to Section 2.19. The Aggregate Commitment shall be reduced by the total Commitments of all Non-Extending Lenders expiring on such previously effective Scheduled Revolving Credit Maturity Date (without giving effect to such Extension Request) unless and until one or more lenders (including other Lenders) shall have agreed to assume a, or increase its, Commitment hereunder (in which case such portion of the Aggregate Commitment shall be reinstated pursuant to this Section). Each Non-Extending Lender shall be required to maintain its original Commitment up to the previously effective Scheduled Revolving Credit Maturity Date (without giving effect to such Extension Request) that such Non-Extending Lender had previously agreed upon.

(d)Replacement of Lender. The Borrower shall have the right at any time to replace each Non-Extending Lender (i) with one or more financial institutions (each, an “Additional Lender”) (A) that are existing Lenders (and, if any such Additional Lender is already a Lender, its Commitment shall be in addition to such Lender's Commitment hereunder on such date) or (B) that are not existing Lenders; provided that any financial institution that is not an existing Lender (x) must be an Eligible Assignee and (y) must become a Lender for all purposes under this Agreement pursuant to an Assignment and Assumption Agreement and (ii) on a non-pro rata basis with any such financial institution that is willing to grant the Extension Request, including at a higher or lower Commitment than such Non-Extending Lenders' respective Commitments; provided that any replacement of one or more Non-Extending Lenders that results in a higher Aggregate Commitment than the Aggregate Commitment in effect prior to such Extension Request shall, to the extent of such excess, be effected pursuant to the requirements of Section 2.22.

Section 2.22.Increase of Aggregate Commitment.

(a)Request of Commitment Increase. At any time and from time to time prior to the Scheduled Revolving Credit Maturity Date, the Borrower shall have the right to request and effectuate increases in the Aggregate Commitment (each a “Commitment Increase”) without the consent of any Lender (other than a Lender that is increasing its Commitment in connection with such request) by adding to this Agreement pursuant to a Commitment Increase Agreement one or more financial institutions as Lenders (collectively, the “New Lenders”) or by allowing one or more existing Lenders to increase their respective Commitments (each an “Increasing Lender”); provided that:

(i)no Lender shall have any obligation to increase its Commitment;

- 37 -

(ii)unless the Agent otherwise consents, each Commitment Increase shall be in a minimum principal amount of $10,000,000 and in integral multiples of $5,000,000 in excess thereof or, if less, the remaining amount permitted pursuant to clause (iii) below;

(iii)in no event shall the aggregate amount of all Commitment Increases result in the Aggregate Commitment exceeding 150% of the Aggregate Commitment in effect on the Closing Date;

(iv)each New Lender must be an Eligible Assignee;

(v)on the effective date of any Increase (the “Increase Date”), the applicable conditions set forth in Section 4.3 shall be satisfied (or waived in accordance with Section 9.1); and

(vi)such increased Commitments shall be on the same terms as the existing Commitments (subject to the Borrower's ability to extend any Commitment pursuant to Section 2.21).

(b)Deliverables for Commitment Increase. Each Commitment Increase must be requested by written notice from the Borrower to the Agent, specifying (x) the proposed Increase Date and (y) the amount of the requested Commitment Increase. To effect a Commitment Increase, the Borrower, the Agent, one or more New Lenders and/or Increasing Lenders (and, to the extent the consent of the LC Issuers and the Swing Line Lender is necessary under the terms of this Agreement, the LC Issuers and the Swing Line Lender) shall execute a Commitment Increase Agreement, and such Commitment Increase shall be effective on the Increase Date specified therein; provided that, as a condition to the effectiveness of any Commitment Increase, if requested by the Agent, the Borrower shall deliver to the Agent:

(i)a certificate dated as of the Increase Date, signed by an Authorized Officer certifying that (A) each of the conditions to such increase set forth in this Section 2.22 shall have occurred and been complied with and (B) attached thereto is a certified copy of resolutions of the board of directors or other equivalent governing body of the General Partner approving such Commitment Increase; and

(ii)a favorable customary opinion of counsel for the Borrower (which may be in-house counsel), in form and substance reasonably acceptable to the Agent, covering such matters relating to the Commitment Increase as the Agent may reasonable request.

(c)Notification of Commitment Increase; Reallocation of Credit Exposure. On each Increase Date, upon fulfillment of the conditions set forth in paragraph (b) above and Section 4.3, (i) the Agent shall notify the Lenders (including each New Lender) and the Borrower of the occurrence of the Commitment Increase effected on such Increase Date and shall record in the Register the relevant information with respect to each Increasing Lender and each New Lender, (ii) the Aggregate Outstanding Credit Exposure will be reallocated among the Lenders in accordance with their revised Pro Rata Shares (and the Lenders agree to make all payments and adjustments necessary to effect the reallocation and the Borrower shall pay any and all costs required pursuant to Section 3.4 in connection with such reallocation as if such reallocation were a repayment) and (iii) each New Lender that executes a Commitment Increase Agreement shall be a Lender for all purposes under this Agreement.

Section 2.23.Swing Line Loans.

(a)Amount of Swing Line Loans. Upon (x) the satisfaction of the conditions precedent set forth in Section 4.2 and (y) if such Swing Line Loan is to be made on the date of the initial Advance hereunder, the satisfaction of the conditions precedent set forth in Section 4.1, from and including the Closing Date and prior to the Revolving Credit Maturity Date, the Borrower may request and the Swing Line Lender shall, on the terms and conditions set forth in this Agreement, make Swing Line Loans to the Borrower from time to time in an aggregate principal amount not to exceed the Swing Line Limit (it being agreed that the Swing Line Lender shall be obligated to make Swing Line Loans even if the aggregate principal amount of Swing Line Loans outstanding and/or requested by the Borrower at any time, when added to the aggregate principal amount of Revolving Loans made by the Swing Line Lender in its capacity as a Lender at such time and its LC Obligations at such time, would exceed the Swing Line Lender's own Commitment as a Lender at such time); provided that at no time shall (i) the Aggregate Outstanding Credit Exposure at any time exceed the Aggregate Commitment or (ii) the sum of (A) the Swing Line Lender's Pro Rata Share of the Swing Line Loans, plus (B) the outstanding Revolving Loans made by the Swing Line Lender pursuant to Section 2.1, plus (C) an amount equal to the Swing Line Lender's ratable obligation to purchase participations in the LC Obligations at such time, exceed the Swing Line Lender's Commitment at such time. Subject to the terms of this Agreement, the Borrower may borrow, repay and reborrow Swing Line Loans at any time prior to the Revolving Credit Maturity Date. Subject to the terms and conditions of this Agreement (including the submission of a Borrowing Notice in compliance with Section 2.8 and the satisfaction of the applicable conditions precedent set forth in Article IV), the Borrower may request an Advance (other than a Swing Line Loan) hereunder for the purpose of repaying any Swing Line Loan.

(b)Borrowing Notice. The Borrower shall deliver to the Agent and the Swing Line Lender irrevocable notice (a “Swing Line Borrowing Notice”) not later than 2:00 p.m. on the Borrowing Date of each Swing Line Loan, specifying (i) the applicable Borrowing Date (which date shall be a Business Day), and (ii) the aggregate amount of the requested Swing Line Loan which shall be an amount not less than $500,000 and in an integral multiple of $100,000 in excess thereof. The Swing Line Loans shall bear interest at the Swing Line Rate.

(c)Making of Swing Line Loans. Promptly after receipt of a Swing Line Borrowing Notice, the Agent shall notify each Lender by fax, or other similar form of transmission, of the requested Swing Line Loan. Not later than 4:00 p.m. on the applicable Borrowing Date, the Swing Line Lender shall make available the Swing Line Loan to the Borrower on the Borrowing Date at the Agent's address specified pursuant to Section 9.20.

(d)Repayment of Swing Line Loans.

(i)Each Swing Line Loan shall be paid in full by the Borrower on or before the earlier of (A) the fourteenth (14th) Business Day after the Borrowing Date for such Swing Line Loan and (B) the Revolving Credit Maturity Date; provided, that such payment shall not be made by the proceeds of any other Swing Line Loans.

(ii)The Swing Line Lender may, by written notice given to the Agent not later than 10:00 a.m. on any Business Day, require the Lenders (including the Swing Line Lender) to acquire participations on such Business Day in all or a portion of the Swing Line Loans outstanding. Such notice shall specify the aggregate amount of Swing Line Loans in which Lenders will participate. Promptly upon receipt of such notice, the Agent will give notice thereof to each Lender, specifying in such notice such Lender's Pro Rata Share of such Swing Line Loan or Swing Line Loans. Each

- 39 -

Lender hereby absolutely and unconditionally agrees, upon receipt of notice as provided above, to pay to the Agent, for the account of the Swing Line Lender, such Lender's Pro Rata Share of such Swing Line Loan or Swing Line Loans. Each Lender acknowledges and agrees that its obligation to acquire participations in Swing Line Loans pursuant to this paragraph is unconditional, continuing, irrevocable and absolute and shall not be affected by any circumstances, including (A) any set-off, counterclaim, recoupment, defense or other right which such Lender may have against the Agent, the Swing Line Lender or any other Person, (B) the occurrence or continuance of a Default or Event of Default, (C) any adverse change in the condition (financial or otherwise) of the Borrower, or (D) any other circumstances, happening or event whatsoever. Each Lender shall comply with its obligation under this Section 2.23(d) by wire transfer of immediately available funds, in the same manner as provided in Section 2. 8 with respect to Revolving Loans made by such Lender (and Section 2.8 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Agent shall promptly pay to the Swing Line Lender the amounts so received from the Lenders. In the event that any Lender fails to make payment to the Agent of any amount due under this Section 2.23(d), the Agent shall be entitled to receive, retain and apply against such obligation the principal and interest otherwise payable to such Lender hereunder until the Agent receives such payment from such Lender or such obligation is otherwise fully satisfied. The Agent shall notify the Borrower of any participations in any Swing Line Loan acquired pursuant to this paragraph, and thereafter payments in respect of such Swing Line Loan shall be made to the Agent and not to the Swing Line Lender. Any amounts received by the Swing Line Lender from the Borrower (or other party on behalf of the Borrower) in respect of a Swing Line Loan after receipt by the Swing Line Lender of the proceeds of a sale of participations therein shall be promptly remitted to the Agent. All of such amounts received by the Agent in payment of Swing Line Loans shall be promptly remitted by the Agent to the Lenders that shall have made their payments pursuant to this paragraph and to the Swing Line Lender, as their interests may appear; provided that any such payment so remitted shall be repaid to the Swing Line Lender or to the Agent, as applicable, if and to the extent such payment is required to be refunded to the Borrower for any reason. The purchase of participations in a Swing Line Loan pursuant to this paragraph shall not relieve the Borrower of any default in the payment thereof.

(iii)In addition, on the fourteenth (14^th) Business Day after the Borrowing Date of any Swing Line Loan, the Borrower shall be deemed to have automatically given notice to the Agent requesting that each Lender make a Revolving Loan in the amount of such Lender's Pro Rata Share of such Swing Line Loan (including any interest accrued and unpaid thereon), for the purpose of repaying such Swing Line Loan, in which case each Lender hereby absolutely and unconditionally agrees to fund to the Agent, for the account of the Swing Line Lender, such Lender's Revolving Loan deemed requested under this clause (iii) at the Agent's address specified pursuant to Section 9.20, no later than 4:00 p.m. on the date such notice is received by the Lender from the Agent if such notice is received at or before 2:00 p.m. (and otherwise before 11:00 a.m. on the next Business Day). Revolving Loans made pursuant to this Section 2.23(d)(iii) shall initially be Base Rate Loans and thereafter may be continued as Base Rate Loans or converted into Eurodollar Loans in the manner provided in Section 2.9 and subject to the other conditions and limitations set forth in this Article II. Unless a Lender shall have notified the Swing Line Lender, prior to its making any Swing Line Loan, that any applicable condition precedent set forth in Section 4.1 or 4.2 had not then been satisfied, such Lender's obligation to make Revolving Loans pursuant to this Section 2.23(d)(iii) to repay Swing Line Loans shall be unconditional, continuing, irrevocable and absolute and shall not be affected by any circumstances, including (A) any set-off, counterclaim, recoupment, defense or other right which such Lender may have against the Agent, the Swing Line Lender or any other Person, (B) the occurrence or continuance of a Default or Event of Default, (C) any adverse change in the condition

- 40 -

(financial or otherwise) of the Borrower, or (D) any other circumstances, happening or event whatsoever.

Section 2.24.Defaulting Lenders.

(a)Defaulting Lender Adjustments. Notwithstanding anything to the contrary contained in this Agreement, if any Lender becomes a Defaulting Lender, then, until such time as such Lender is no longer a Defaulting Lender, to the extent permitted by Applicable Law:

(i)Waivers and Amendments. Such Defaulting Lender's right to approve or disapprove any amendment, waiver or consent with respect to this Agreement shall be restricted as set forth in Section 9.1(b).

(ii)Defaulting Lender Waterfall. Any payment of principal, interest, fees or other amounts received by the Agent for the account of such Defaulting Lender (whether voluntary or mandatory, at maturity, pursuant to Article VIII or otherwise) or received by the Agent from a Defaulting Lender pursuant to Section 11.1 will not be paid or distributed to such Defaulting Lender, but will instead be retained by the Agent in a segregated account until (subject to Section 2.24(b)) the termination of the Commitments and payment in full of all obligations of the Borrower hereunder and shall be applied at such time or times as may be determined by the Agent as follows: first, to the payment of any amounts owing by such Defaulting Lender to the Agent hereunder; second, to the payment on a pro rata basis of any amounts owing by such Defaulting Lender to any LC Issuer or the Swing Line Lender hereunder; third, to Cash Collateralize the LC Issuers' Fronting Exposure with respect to such Defaulting Lender in accordance with Section 2.20(m); fourth, as the Borrower may request (so long as no Default or Event of Default exists), to the funding of any Loan in respect of which such Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by the Agent; fifth, if so requested by the Borrower, to be held in a deposit account and released pro rata in order to (x) satisfy such Defaulting Lender's potential future funding obligations with respect to Loans under this Agreement and (y) Cash Collateralize the LC Issuers' future Fronting Exposure with respect to such Defaulting Lender with respect to future Facility LCs issued under this Agreement, in accordance with Section 2.20(m); sixth, to the payment of any amounts owing to the Lenders, the LC Issuers or the Swing Line Lender as a result of any judgment of a court of competent jurisdiction obtained by any Lender, any LC Issuer or the Swing Line Lender against such Defaulting Lender as a result of such Defaulting Lender's breach of its obligations under this Agreement; seventh, so long as no Event of Default exists, to the payment of any amounts owing to the Borrower as a result of any judgment of a court of competent jurisdiction obtained by the Borrower against such Defaulting Lender as a result of such Defaulting Lender's breach of its obligations to the Borrower under this Agreement; and eighth, to such Defaulting Lender or as otherwise directed by a court of competent jurisdiction; provided that if (x) such payment is a payment of the principal amount of any Loans or LC Obligations in respect of which such Defaulting Lender has not fully funded its appropriate share, and (y) such Loans were made or the related Facility LCs were issued at a time when the conditions set forth in Section 4.2 were satisfied or waived, such payment shall be applied solely to pay the Loans of, and LC Obligations owed to, all Non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Loans of, or LC Obligations owed to, such Defaulting Lender until such time as all Loans and funded and unfunded participations in LC Obligations and Swing Line Loans are held by the Lenders pro rata in accordance with the Aggregate Commitments without giving effect to Section 2.24(a)(iv). Any payments, prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a

- 41 -

Defaulting Lender or to post Cash Collateral pursuant to this Section 2.24(a)(ii) shall be deemed paid to and redirected by such Defaulting Lender, and each Lender irrevocably consents hereto.

(iii)Certain Fees.

(A)Anything herein to the contrary notwithstanding, during such period as a Lender is a Defaulting Lender, such Defaulting Lender will not be entitled to any fees accruing during such period pursuant to Section 2.5 and Section 2.20(e) (without prejudice to the rights of the Non-Defaulting Lenders in respect of such fees) and the Borrower shall not be required to pay any fee that otherwise would not have been required to have been paid to that Defaulting Lender, provided, however that each Defaulting Lender shall be entitled to receive LC Participation Fees for any period during which that Lender is a Defaulting Lender to the extent (and only to the extent) allocable to its Pro Rata Share of the outstanding undrawn face amount of Facility LCs for which it has provided Cash Collateral pursuant to Section 2.20(m).

(B)With respect to any LC Participation Fees not required to be paid to any Defaulting Lender pursuant to clause (A) above, the Borrower shall (x) pay to each Non-Defaulting Lender that portion of any such LC Participation Fee otherwise payable to such Defaulting Lender with respect to such Defaulting Lender's participation in LC Obligations that has been reallocated to such Non-Defaulting Lender pursuant to clause (iv) below, (y) pay to each LC Issuer the amount of any such LC Participation Fee otherwise payable to such Defaulting Lender to the extent allocable to such LC Issuer's unreallocated or non-Cash Collateralized Fronting Exposure to such Defaulting Lender, if any, and (z) not be required to pay the remaining amount of any such LC Participation Fee.

(iv)Reallocation of Participations to Reduce Fronting Exposure. All or any part of such Defaulting Lender's Fronting Exposure shall be automatically reallocated (effective on the day such Lender becomes a Defaulting Lender) among the Non-Defaulting Lenders in accordance with their respective Pro Rata Shares (calculated without regard to such Defaulting Lender's Commitment) but only to the extent that (x) the conditions set forth in Section 4.2 are satisfied at the time of such reallocation (and, unless the Borrower shall have otherwise notified the Agent at such time, the Borrower shall be deemed to have represented and warranted that such conditions are satisfied at such time), and (y) such reallocation does not cause the Outstanding Credit Exposure of any Non-Defaulting Lender to exceed such Non-Defaulting Lender's Commitment. No reallocation hereunder shall constitute a waiver or release of any claim of any party hereunder against a Defaulting Lender arising from that Lender having become a Defaulting Lender, including any claim of a Non-Defaulting Lender as a result of such Non-Defaulting Lender's increased exposure following such reallocation.

(v)Cash Collateral, Repayment of Swing Line Loans. If the reallocation described in clause (iv) above cannot, or can only partially, be effected, the Borrower shall not later than two (2) Business Days after written demand by the Agent (at the direction of any LC Issuer and/or the Swing Line Lender, as the case may be), without prejudice to any right or remedy available to it hereunder or under law, first, prepay Swing Line Loans in an amount equal to the Swing Line Lender's Fronting Exposure, and second, Cash Collateralize the LC Issuers' Fronting Exposure in accordance with the procedures set forth in Section 2.20(m).

- 42 -

(b)Defaulting Lender Cure. If the Borrower, the Agent, the Swing Line Lender and each LC Issuer agree in writing that a Lender is no longer a Defaulting Lender, the Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may include arrangements with respect to any Cash Collateral), such Lender will, to the extent applicable, purchase at par that portion of outstanding Loans of the other Lenders and take such other actions as the Agent may determine to be necessary to cause the Loans and funded and unfunded participations in Facility LCs and Swing Line Loans to be held pro rata by the Lenders in accordance with the Aggregate Commitments (without giving effect to Section 2.24(a)(iv)), whereupon such Lender will cease to be a Defaulting Lender (and the Pro Rata Shares of each Lender will automatically be adjusted on a prospective basis to reflect the foregoing); provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrower while that Lender was a Defaulting Lender; and provided, further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Non-Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender's having been a Defaulting Lender.

(c)New Swing Line Loans/Facility LCs. So long as any Lender is a Defaulting Lender, (i) the Swing Line Lender shall not be required to fund any Swing Line Loans unless it is satisfied that it will have no Fronting Exposure with respect to such Defaulting Lender's participation interest therein after giving effect to such Swing Line Loan and (ii) no LC Issuer shall be required to issue or Modify any Facility LC unless it is satisfied that it will have no Fronting Exposure with respect to such Defaulting Lender's participation interest therein after giving effect thereto, in each case, after giving effect to such issuance or Modification, and after giving effect to any Cash Collateral provided in respect of, or reallocation pursuant to Section 2.24(a)(iv) of, such LC Issuer's or Swing Line Lender's Fronting Exposure with respect to such Defaulting Lender.

Section 2.25.Obligations of Lenders.

(a)Funding by Lenders; Presumption by the Agent. Unless the Agent shall have received notice from a Lender prior to the proposed time of any borrowing that such Lender will not make available to the Agent such Lender's share of such Advance, the Agent may assume that such Lender has made such share available on such date in accordance with the terms hereof and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable borrowing available to the Agent, then the applicable Lender and the Borrower severally agree to pay to the Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Agent, at (i) in the case of a payment to be made by such Lender, the greater of the daily average Federal Funds Effective Rate and a rate determined by the Agent in accordance with banking industry rules on interbank compensation and (ii) in the case of a payment to be made by the Borrower, the interest rate applicable to such Loans. If the Borrower and such Lender shall pay such interest to the Agent for the same or an overlapping period, the Agent shall promptly remit to the Borrower the amount of such interest paid by the Borrower for such period. If such Lender pays its share of the applicable Advance to the Agent, then the amount so paid shall constitute such Lender's Loan included in such borrowing. Any payment by the Borrower shall be without prejudice to any claim the Borrower may have against a Lender that shall have failed to make such payment to the Agent.

(b)Nature of Obligations of Lenders Regarding Extensions of Credit. The obligations of the Lenders under this Agreement to make the Loans or participate in Facility LCs are several and are not joint or joint and several. The failure of any Lender to make available its Pro Rata Share of any Advance requested by the Borrower shall not relieve it or any other Lender of its obligation, if any, hereunder to make

- 43 -

its Pro Rata Share of such Advance available on the Borrowing Date, but no Lender shall be responsible for the failure of any other Lender to make its Pro Rata Share of such Advance available on the Borrowing Date.

ARTICLE III.

YIELD PROTECTION; TAXES

Section 3.1.Yield Protection.

(a)Increased Costs Generally. If any Change in Law shall:

(i)impose, modify or deem applicable any reserve, special deposit, compulsory loan or similar requirement against assets of, deposits with or for the account of, or credit extended or participated in by, any Lender or any LC Issuer;

(ii)subject any Recipient to any Taxes (other than (A) Indemnified Taxes, (B) Taxes described in clauses (b) through (d) of the definition of Excluded Taxes and (C) Other Connection Taxes) on its loans, loan principal, letters of credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto; or

(iii)impose on any Lender, any LC Issuer or the London interbank market any other condition, cost or expense (other than Taxes) affecting this Agreement or Loans made by such Lender or any Facility LC or participation therein;

and the result of any of the foregoing shall be to increase the cost to the Agent or such other Recipient of making, converting into, continuing or maintaining any Loan (or of maintaining its obligation to make any such Loan), or to increase the cost to such Recipient of participating in, issuing or maintaining any Facility LC (or of maintaining its obligation to participate in or to issue any Facility LC), or to reduce the amount of any sum received or receivable by such Recipient hereunder (whether of principal, interest or any other amount) then, upon written request of such Recipient, the Borrower shall promptly pay to such Recipient such additional amount or amounts as will compensate such Recipient for such additional costs incurred or reduction suffered; provided that the Borrower shall not be required to pay any such amounts to any Recipient under and pursuant to this Section which are owing as a result of any Specified Change if and to the extent such Recipient is not at such time generally assessing such costs in a similar manner to other similarly situated borrowers with similar credit facilities.

(b)Capital Requirements. If any Lender or LC Issuer determines that any Change in Law affecting such Lender or LC Issuer or any Lending Installation of such Lender or such Lender's or LC Issuer's holding company, if any, regarding capital or liquidity requirements, has or would have the effect of reducing the rate of return on such Lender's or LC Issuer's capital or on the capital of such Lender's or LC Issuer's holding company, if any, as a consequence of this Agreement, the Commitments of such Lender or the Loans made by, or participations in Facility LCs or Swing Line Loans held by, such Lender, or the Facility LCs issued by any LC Issuer, to a level below that which such Lender or LC Issuer or such Lender's or LC Issuer's holding company could have achieved but for such Change in Law (taking into consideration such Lender's or LC Issuer's policies and the policies of such Lender's or LC Issuer's holding company with respect to capital adequacy and liquidity), then from time to time the Borrower will pay to such Lender or LC Issuer, as the case may be, such additional amount or amounts as will compensate such Lender or LC Issuer or such Lender's or LC Issuer's holding company for any such reduction suffered; provided that the Borrower shall

- 44 -

not be required to pay any such amounts to any Lender under and pursuant to this Section which are owing as a result of any Specified Change if and to the extent such Lender is not at such time generally assessing such costs in a similar manner to other similarly situated borrowers with similar credit facilities.

(c)Delay in Requests. Failure or delay on the part of any Lender or LC Issuer to demand compensation pursuant to this Section shall not constitute a waiver of such Lender's or LC Issuer's right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender or LC Issuer pursuant to this Section for any increased costs incurred or reductions suffered more than ninety (90) days prior to the date that such Lender or LC Issuer, as the case may be, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions, and of such Lender's or LC Issuer's intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the ninety-day period referred to above shall be extended to include the period of retroactive effect thereof).

Section 3.2.Changed Circumstances Affecting Eurodollar Rate Availability. In connection with any request for a Eurodollar Advance or a Base Rate Advance or a conversion to or continuation thereof, if for any reason (a) the Agent shall determine (which determination shall be conclusive and binding absent manifest error) that Dollar deposits are not being offered to banks in the London interbank Eurodollar market for the applicable amount and Interest Period of such Advance, (b) the Agent shall determine (which determination shall be conclusive and binding absent manifest error) that reasonable and adequate means do not exist for ascertaining the Eurodollar Rate for such Advance or (c) the Required Lenders shall determine (which determination shall be conclusive and binding absent manifest error) that the Eurodollar Rate does not adequately and fairly reflect the cost to such Lenders of making or maintaining such Advance during such Interest Period, then the Agent shall promptly give notice thereof to the Borrower and the other Lenders. Thereafter, until the Agent notifies the Borrower and the other Lenders that such circumstances no longer exist, (i) the obligation of the Lenders to make Eurodollar Advances and the right of the Borrower to convert any Advance to or continue any Advance as a Eurodollar Advance shall be suspended, and the Borrower shall, at the Borrower's option, either (A) repay in full (or cause to be repaid in full) the then outstanding principal amount of each such Eurodollar Advance together with accrued interest thereon (subject to Section 2.15), on the last day of the then current Interest Period applicable to such Eurodollar Advance; or (B) convert, without premium or penalty and without liability for any amounts payable pursuant to Section 3.4, the then outstanding principal amount of each such Eurodollar Advance to a Base Rate Advance as of the last day of such Interest Period; and (ii) the Alternate Base Rate shall be calculated without giving effect to clause (c) of such definition.

Section 3.3.Laws Affecting Eurodollar Rate Availability. If, after the date hereof, the introduction of, or any change in, any Applicable Law or any change in the interpretation or administration thereof by any Governmental Authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any of the Lenders (or any of their respective Lending Installations) with any request or directive (whether or not having the force of law) of any such Governmental Authority, central bank or comparable agency, shall make it unlawful or impossible for any of the Lenders (or any of their respective Lending Installations) to honor its obligations hereunder to make or maintain any Eurodollar Advance, such Lender shall promptly give notice thereof to the Agent and the Agent shall promptly give notice to the Borrower and the other Lenders. Thereafter, until the Agent notifies the Borrower and the other Lenders that such circumstances no longer exist, (i) the obligations of the Lenders to make Eurodollar Advances, and the right of the Borrower to convert any Advance or continue any Advance as a Eurodollar Advance shall be suspended and thereafter the Borrower may select only Base Rate Loans, (ii) if any of the Lenders may not lawfully continue to maintain a Eurodollar Advance to the end of the then current Interest

- 45 -

Period applicable thereto, the applicable Loan shall immediately be converted to a Base Rate Loan for the remainder of such Interest Periodand (iii) the Alternate Base Rate shall be calculated without giving effect to clause (c) of such definition.

Section 3.4.Funding Indemnification. If (i) any payment of a Eurodollar Advance occurs on a date which is not the last day of the applicable Interest Period, whether because of acceleration, prepayment or otherwise, including pursuant to Section 9.19, (ii) a Eurodollar Advance is not made, continued or converted on the date specified by the Borrower in a Borrowing Notice or a Conversion/Continuation Notice for any reason other than default by the Lenders, (iii) a Eurodollar Advance is not prepaid on the date specified by the Borrower pursuant to Section 2.7 for any reason, or (iv) a Eurodollar Loan is assigned on a date which is not the last day of the applicable Interest Period as a result of a request by the Borrower pursuant to Section 2.19, then, except (a) as otherwise provided in this Agreement or (b) if arising in connection with a Lender becoming a Defaulting Lender or the replacement of such Lender pursuant to Section 2.19, for any such amounts that would be owing to such Lender, the Borrower will indemnify each Lender for any loss or cost incurred by it resulting therefrom, including any loss or cost in liquidating or employing deposits acquired to fund or maintain such Eurodollar Advance but excluding the Applicable Margin expected to be received by such Lender during the remainder of such Interest Period.

Section 3.5.Taxes.

(a)LC Issuers. For purposes of this Section 3.5, the term “Lender” includes any LC Issuer.

(b)Payments Free of Taxes.Any and all payments to a Recipient by or on account of any obligation of the Borrower under any Loan Document shall be made without deduction or withholding for any Taxes, except as required by Applicable Law. If any Applicable Law (as determined in the good faith discretion of an applicable Withholding Agent) requires the deduction or withholding of any Tax from any such payment by a Withholding Agent, then the applicable Withholding Agent shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with Applicable Law and, if such Tax is an Indemnified Tax, then the sum payable by the Borrower shall be increased as necessary so that after such deduction or withholding has been made (including such deductions and withholdings applicable to additional sums payable under this Section) the applicable Recipient receives an amount equal to the sum it would have received had no such deduction or withholding for Indemnified Tax been made.

(c)Payment of Other Taxes by the Borrower.The Borrower shall timely pay to the relevant Governmental Authority in accordance with Applicable Law, or at the option of the Agent timely reimburse it for the payment of, any Other Taxes.

(d)Indemnification by the Borrower.The Borrower shall indemnify each Recipient, within 30 days after demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section) payable or paid by such Recipient or required to be withheld or deducted from a payment to such Recipient and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority; provided, however, the Borrower shall not be required to indemnify a Recipient pursuant to this Section 3.5(d) for any Indemnified Taxes unless such Recipient makes written demand on the Borrower for indemnification for such Indemnified Taxes no later than one hundred twenty (120) days after the earlier of (i) the date on which the relevant Governmental Authority makes written demand upon such Recipient for payment of such Indemnified Taxes, and (ii) the

- 46 -

date on which such Recipient has made payment of such Indemnified Taxes. A certificate satisfying the requirements of Section 3.6 as to the amount of such payment or liability delivered to the Borrower by a Lender (with a copy to the Agent), or by the Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error.

(e)Indemnification by the Lenders.Each Lender shall severally indemnify the Agent, within 10 days after demand therefor, for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that the Borrower has not already indemnified the Agent for such Indemnified Taxes and without limiting the obligation of Borrower to do so), (ii) any Taxes attributable to such Lender's failure to comply with the provisions of Section 12.2 relating to the maintenance of a Participant Register and (iii) any Excluded Taxes attributable to such Lender, in each case, that are payable or paid by the Agent in connection with any Loan Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any Lender by the Agent shall be conclusive absent manifest error. Each Lender hereby authorizes the Agent to set off and apply any and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by the Agent to the Lender from any other source against any amount due to the Agent under this Section 3.5(e).

(f)Evidence of Payments. As soon as practicable after any payment of Taxes by the Borrower to a Governmental Authority pursuant to this Section 3.5, the Borrower shall deliver to the Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Agent.

(g)Status of Lenders.

(i)Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Loan Document shall deliver to the Borrower and the Agent, at the time or times reasonably requested by the Borrower or the Agent, such properly completed and executed documentation reasonably requested by the Borrower or the Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably requested by the Borrower or the Agent, shall deliver such other documentation prescribed by Applicable Law or reasonably requested by the Borrower or the Agent as will enable the Borrower or the Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Sections 3.5(g)(ii)(A), (ii)(B) and (ii)(D) below) shall not be required if in such applicable Lender's reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender.

(ii)Without limiting the generality of the foregoing,

(A)any Lender that is a U.S. Person shall deliver to the Borrower and the Agent on or prior to the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Agent), properly completed and executed originals of IRS Form W-9 certifying that such Lender is exempt from U.S. federal backup withholding Tax;

- 47 -

(B)any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Agent), whichever of the following is applicable:

(1)in the case of a Foreign Lender claiming the benefits of an income Tax treaty to which the United States is a party (x) with respect to payments of interest under any Loan Document, properly completed and executed originals of IRS Form W‑8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “interest” article of such Tax treaty and (y) with respect to any other applicable payments under any Loan Document, properly completed and executed originals of IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “business profits” or “other income” article of such Tax treaty;

(2)properly completed and executed originals of IRS Form W-8ECI;

(3)in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code, (x) a certificate substantially in the form of Exhibit E-1 to the effect that such Foreign Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, a “10 percent shareholder” of the Borrower within the meaning of Section 881(c)(3)(B) of the Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code (a “U.S. Tax Compliance Certificate”) and (y) properly completed and executed originals of IRS Form W-8BEN; or

(4)to the extent a Foreign Lender is not the beneficial owner, properly completed and executed originals of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN, a U.S. Tax Compliance Certificate substantially in the form of Exhibit E-2 or E-3, IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Foreign Lender is a partnership and one or more direct or indirect partners of such Foreign Lender are claiming the portfolio interest exemption, such Foreign Lender may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit E-4 on behalf of each such direct and indirect partner;

(C)any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Agent), executed originals of any other form prescribed by Applicable Law as a basis for claiming exemption from or a reduction in U.S. federal withholding Tax, duly completed, together with such supplementary documentation as may be prescribed by Applicable Law to permit the Borrower or the Agent to determine the withholding or deduction required to be made; and

- 48 -

(D)if a payment made to a Lender under any Loan Document would be subject to U.S. federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Borrower and the Agent at the time or times prescribed by Applicable Law and at such time or times reasonably requested by the Borrower or the Agent such documentation prescribed by Applicable Law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower or the Agent as may be necessary for the Borrower and the Agent to comply with their obligations under FATCA and to determine that such Lender has complied with such Lender's obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (D), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

(iii)To the extent the Agent is not acting as a Lender, the Agent shall comply with the requirements of this Section 3.5(g) to the same extent as if it were a Lender (whose obligations under this Section 3.5(g) shall be solely to the Borrower) since the date on which it became the Agent.

Each Lender agrees that if any form or certification it previously delivered expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the Borrower and the Agent in writing of its legal inability to do so.

(h)Treatment of Certain Refunds.If any party determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Section 3.5 (including by the payment of additional amounts pursuant to this Section 3.5), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such indemnified party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over pursuant to this Section 3.5(h) (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event that such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this Section 3.5(h), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this Section 3.5(h) the payment of which would place the indemnified party in a less favorable net after-Tax position than the indemnified party would have been in if the Tax subject to indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax had never been paid. This paragraph shall not be construed to require any indemnified party to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the indemnifying party or any other Person.

(i)Survival. Each party's obligations under this Section 3.5 shall survive the resignation or replacement of the Agent or any assignment of rights by, or the replacement of, a Lender, the termination of the Commitments and the repayment, satisfaction or discharge of all obligations under any Loan Document.

(j)Applicable Law. For purposes of this Section 3.5, the term “Applicable Law” includes FATCA.

- 49 -

Section 3.6.Lender Statements; Survival of Indemnity.Each Lender shall deliver a written statement of such Lender to the Borrower (with a copy to the Agent) as to the amount due, if any, under Section 3.1, 3.2, 3.4 or 3.5. Such written statement shall set forth in reasonable detail the calculations upon which such Lender determined such amount and shall be final, conclusive and binding on the Borrower in the absence of manifest error. Determination of amounts payable under such Sections in connection with a Eurodollar Loan shall be calculated as though each Lender funded its Eurodollar Loan through the purchase of a deposit of the type and maturity corresponding to the deposit used as a reference in determining the Eurodollar Rate applicable to such Loan, whether in fact that is the case or not. Unless otherwise provided herein, the amount specified in the written statement of any Lender shall (unless the subject of a good faith dispute by the Borrower) be payable within fifteen (15) days after demand and receipt by the Borrower of such written statement. The obligations of the Borrower under Sections 3.1, 3.2, 3.4 and 3.5 shall survive payment of the Obligations and termination of this Agreement.

Section 3.7.Alternative Lending Installation.If any Lender requests compensation under Section 3.1, or the Borrower is required to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 3.5, or is unable to fund or maintain Eurodollar Advances or Eurodollar Loans, as applicable, as a result of the circumstances described in Section 3.3, then such Lender shall (at the request of the Borrower) use reasonable efforts to designate a different Lending Installation for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 3.1 or 3.5 or remedy the circumstances described in Section 3.3, as the case may be, in the future, and (ii) would not in the reasonable judgment of such Lender subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. A Lender shall not be required to make any such designation or assignment if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances requiring such designation or assignment cease to apply. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment, if and to the extent such Lender is at such time generally assessing such costs and expenses in a similar manner to other similarly situated borrowers with similar credit facilities.

Section 9.11.Nonliability; Waiver of Consequential Damages. The relationship between the Borrower on the one hand and the Lenders and the Agent on the other hand shall be solely that of borrower and lender.

Each party hereto agrees that no other party hereto nor any of its Related Parties shall have any liability to any other party hereto (or its Related Parties) on any theory of liability for any special, indirect, consequential or punitive damages (including without limitation, any loss of profits, business or anticipated savings) in connection with, arising out of, or in any way related to the Loan Documents or the transactions contemplated thereby; provided that this waiver shall in no way limit the Borrower's indemnification obligations in Section 9.7(b) to the extent of any third-party claim for any of the foregoing, including the Borrower's obligation to indemnify Indemnitees for special, indirect, consequential or punitive damages awarded against an Indemnitee.

Section 9.13.Lenders Not Utilizing Plan Assets.

ARTICLE X.

THE AGENT

Section 10.1.Appointment and Authority. Each of the Lenders and the LC Issuers hereby irrevocably designates and appoints Citibank to act on its behalf as the Agent hereunder and under the other Loan Documents and authorizes the Agent to take such actions on its behalf and to exercise such powers as are delegated to the Agent by the terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto. The provisions of this Article are solely for the benefit of the Agent, the LC Issuers and the Lenders, and neither the Borrower nor any Subsidiary thereof shall have rights as a third party beneficiary of any of such provisions. It is understood and agreed that the use of the term “agent” herein or in any other Loan Documents (or any other similar term) with reference to the Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead such term is used as a matter of market custom, and is intended to create or reflect only an administrative relationship between contracting parties.

Section 10.2.Rights as a Lender. The Person serving as the Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Agent and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, own securities of, act as the financial advisor or in any other advisory capacity for, and generally engage in any kind of business with, the Borrower or any Subsidiary or other Affiliate thereof as if such Person were not the Agent hereunder and without any duty to account therefor to the Lenders.

- 76 -

Section 10.3.Exculpatory Provisions. The Agent shall not have any duties or obligations except those expressly set forth herein and in the other Loan Documents, and its duties hereunder shall be administrative in nature. Without limiting the generality of the foregoing, the Agent:

(a)shall not be subject to any fiduciary or other implied duties, regardless of whether an Event of Default has occurred and is continuing;

(b)shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that the Agent is required to exercise as directed in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be expressly provided for herein or in the other Loan Documents); provided that the Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Agent to liability or that is contrary to any Loan Document or Applicable Law, including for the avoidance of doubt, any action that may be in violation of the automatic stay under any Debtor Relief Law or that may effect a forfeiture, modification or termination of property of a Defaulting Lender in violation of any Debtor Relief Law; and

(c)shall not, except as expressly set forth herein and in the other Loan Documents, have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower or any of its Affiliates that is communicated to or obtained by the Person serving as the Agent or any of its Affiliates in any capacity.

The Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary, or as the Agent shall believe in good faith shall be necessary, under the circumstances as provided in Section 9.1) or (ii) in the absence of its own gross negligence, bad faith or willful misconduct as determined by a court of competent jurisdiction by a final and nonappealable judgment. The Agent shall be deemed not to have knowledge of any Default or Event of Default unless and until notice describing such Default or Event of Default is given to the Agent in writing by the Borrower, a Lender or an LC Issuer.

The Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default or Event of Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document or (v) the satisfaction of any condition set forth in Article IV or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Agent.

Section 10.4.Reliance by the Agent. The Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, Internet or intranet website posting or other distribution) reasonably believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. The Agent also may rely upon any statement made to it orally or by telephone and reasonably believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of a Loan, or the issuance or Modification of a Facility LC, that by its terms must be fulfilled to the satisfaction of a Lender or an LC Issuer, the Agent may presume that such condition is satisfactory to such Lender or LC Issuer unless the Agent shall have received notice to the contrary from such Lender or LC Issuer prior to the making of such Loan or the issuance

- 77 -

or Modification of such Facility LC. The Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

Section 10.5.Delegation of Duties. The Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Loan Document by or through any one or more sub-agents selected and appointed by the Agent. The Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties. The exculpatory provisions of this Article shall apply to any such sub-agent and to the Related Parties of the Agent and any such sub agent, and shall apply to their respective activities in connection with the syndication of the credit facility evidenced hereby as well as activities as Agent. The Agent shall not be responsible for the negligence or misconduct of any sub-agents except to the extent that a court of competent jurisdiction determines in a final and nonappealable judgment that the Agent acted with gross negligence, bad faith or willful misconduct in the selection of such sub-agents.

Section 10.6.Resignation of Agent.

(a)The Agent may at any time give notice of its resignation to the Lenders, the LC Issuers and the Borrower. Upon receipt of any such notice of resignation, the Required Lenders shall have the right, in consultation with the Borrower (and so long as no Event of Default shall have occurred and be continuing, subject to the approval of the Borrower, such approval not to be unreasonably withheld or delayed (it being understood and agreed that if such proposed successor Agent is unwilling or unable to be appointed as the successor Swing Line Lender or LC Issuer, as applicable, it shall not be unreasonable for the Borrower to withhold its consent)), to appoint a successor from among the Lenders, which shall be a bank with an office in the United States having capital and retained earnings of at least $100,000,000, or an Affiliate of any such bank with an office in the United States. If no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Agent gives notice of its resignation (or such earlier day as shall be agreed by the Required Lenders) (the “Resignation Effective Date”), then the retiring Agent may (but shall not be obligated to), on behalf of the Lenders and the LC Issuers, appoint a successor Agent meeting the qualifications set forth above; provided that if the Agent shall notify the Borrower and the Lenders that no qualifying Person has accepted such appointment, then all payments, communications and determinations provided to be made by, to or through the Agent shall instead be made by or to each Lender directly, until such time as the Required Lenders appoint a successor Agent as provided for above in this paragraph (with the approval of the Borrower to the extent required above). Whether or not a successor has been appointed, such resignation of the retiring Agent shall become effective in accordance with such notice on the Resignation Effective Date (except that in the case of any collateral security held by the retiring Agent on behalf of the Lenders, the Swing Line Lender or any LC Issuer under any of the Loan Documents, the retiring Agent shall continue to hold such collateral security until such time as a successor Agent is appointed and accepts such appointment).

(b)With effect from the Resignation Effective Date (1) the retiring Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents and (2) except for any indemnity payments owed to the retiring Agent, all payments, communications and determinations provided to be made by, to or through the Agent shall instead be made by or to each Lender and LC Issuer directly, until such time, if any, as the Required Lenders appoint a successor Agent as provided for above. Upon the acceptance of a successor's appointment as Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring or retired Agent (other than any rights to indemnity payments owed to the retiring Agent), and the retiring Agent shall be discharged from all of its duties and obligations hereunder or under the other Loan Documents. The fees payable by

- 78 -

the Borrower to a successor Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the retiring Agent's resignation hereunder and under the other Loan Documents, the provisions of this Article X and Section 9.7 shall continue in effect for the benefit of such retiring Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring Agent was acting as Agent. In the event that there is a successor to the Agent by merger, or the Agent assigns its duties and obligations to an Affiliate pursuant to this Section 10.6, then the term “Prime Rate” as used in this Agreement shall mean the prime rate, base rate or other analogous rate of the new Agent.

(c)Any resignation by Citibank as Agent pursuant to this Section shall, unless otherwise agreed, also constitute its resignation (as of the Resignation Effective Date) as an LC Issuer and Swing Line Lender (but, in the case of the LC Issuer, only with respect to any Facility LCs issued after such date of resignation). Upon the acceptance of a successor's appointment as Agent hereunder (i) such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring LC Issuer and Swing Line Lender, (ii) the retiring LC Issuer and Swing Line Lender shall be discharged from all of its duties and obligations in such capacities hereunder or under the other Loan Documents, and (iii) after such acceptance, the successor LC Issuer shall use commercially reasonable efforts to issue letters of credit in substitution for the Facility LCs issued by the retiring LC Issuer, if any, outstanding at the time of such succession.

Section 10.7.Non-Reliance on Agent and Other Lenders. Each Lender and LC Issuer acknowledges that it has, independently and without reliance upon the Agent or any other Lender or any of their Related Parties and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender and LC Issuer also acknowledges that it will, independently and without reliance upon the Agent or any other Lender or any of their Related Parties and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document or any related agreement or any document furnished hereunder or thereunder.

Section 10.8.No Other Duties, etc. Anything herein to the contrary notwithstanding, none of the Syndication Agent, the Co-Documentation Agents, or the Arrangers listed on the cover page or signature pages hereof shall have any powers, duties or responsibilities under this Agreement or any of the other Loan Documents, except in its capacity, as applicable, as the Agent, a Lender or an LC Issuer hereunder.

Section 10.9.Agent, Arrangers and Co-Documentation Agent Fees. The Borrower agrees to pay to the Agent, each Arranger and each Co-Documentation Agent, for their respective accounts, the fees agreed to by the Borrower pursuant to the applicable Fee Letters.

Section 10.10.Reimbursement and Indemnification.

(a)The Lenders agree to reimburse and indemnify the Agent, the Syndication Agent, the Arrangers and the Co-Documentation Agents ratably in proportion to the Lenders' Pro Rata Shares of the Aggregate Commitment (or, if the Aggregate Commitment has been terminated, of the Outstanding Credit Exposure) for any amounts not reimbursed by the Borrower (a) for which the Agent, the Syndication Agent, any Arranger or any Co-Documentation Agent is entitled to reimbursement by the Borrower under the Loan Documents, (b) for any other expenses incurred by the Agent, the Syndication Agent, any Arranger or any Co-Documentation Agent on behalf of the Lenders, in connection with the preparation, execution, delivery, administration and enforcement of the Loan Documents and (b) for any liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind and nature

- 79 -

whatsoever which may be imposed on, incurred by or asserted against the Agent, the Syndication Agent, any Arranger or any Co-Documentation Agent in any way relating to or arising out of the Loan Documents or any other document delivered in connection therewith or the transactions contemplated thereby (including for any such amounts incurred by or asserted against the Agent, the Syndication Agent, any Arranger or any Co-Documentation Agent in connection with any dispute between the Agent, the Syndication Agent, any Arranger any Co-Documentation Agent and any Lender or between two or more of the Lenders), or the enforcement of any of the terms of the Loan Documents or of any such other documents (collectively, the “Indemnified Costs”); provided that (i) no Lender shall be liable for any portion of the Indemnified Costs that are found in a final non-appealable judgment by a court of competent jurisdiction to have resulted from the gross negligence, bad faith or willful misconduct of the party seeking indemnification and (ii) any indemnification required pursuant to Section 3.4 shall, notwithstanding the provisions of this Section 10.9, be paid by the relevant Lender in accordance with the provisions thereof. The failure of any Lender to reimburse the Agent, the Syndication Agent, any Arranger or any Co-Documentation Agent, as the case may be, promptly upon demand for its Pro Rata Share of any amount required to be paid by the Lenders as provided herein shall not relieve any other Lender of its obligation hereunder to reimburse the Agent, the Syndication Agent, any Arranger or any Co-Documentation Agent, as the case may be, for its Pro Rata Share of such amount, but no Lender shall be responsible for the failure of any other Lender to reimburse such Agent, Syndication Agent, Arranger or Co-Documentation Agent, as the case may be, for such other Lender's Pro Rata Share of such amount. The obligations of the Lenders under this Section 10.9 shall survive payment of the Obligations and termination of this Agreement.

(b)Each Lender shall, ratably in accordance with its Pro Rata Share, indemnify the LC Issuers, and their respective Related Parties (to the extent not reimbursed by the Borrower) against any cost, expense (including reasonable counsel fees and disbursements), claim, demand, action, loss or liability (except as result from such indemnitees' gross negligence, bad faith or willful misconduct, as determined by a court of competent jurisdiction by final non-appealable judgment) that any such indemnitees may suffer or incur in connection with the Loan Documents or any action taken or omitted by such indemnitee under the Loan Documents.

Section 10.11.Agent May File Proofs of Claim. In case of the pendency of any proceeding under any Debtor Relief Law, the Lenders hereby agree that the Agent (irrespective of whether the principal of any Loan or LC Obligation shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Agent shall have made any demand on the Borrower) shall be entitled and empowered (but not obligated) by intervention in such proceeding or otherwise for and on behalf of the Lenders:

(a)to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans, LC Obligations and all other Obligations that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Lenders, the LC Issuers and the Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders, the LC Issuers and the Agent and their respective agents and counsel and all other amounts due the Lenders and the Agent under Sections 2.5, 2.20(d), 9.7 and 10.9) allowed in such judicial proceeding; and

Section 10.12.Trust Indenture Act. In the event that Citibank or any of its Affiliates shall be or become an indenture trustee under the Trust Indenture Act of 1939 (as amended, the “Trust Indenture Act”) in respect of any securities issued or guaranteed by the Borrower or any of its Subsidiaries, the parties hereto acknowledge and agree that any payment or property received in satisfaction of or in respect of any Obligation of the Borrower or any of its Subsidiaries hereunder or under any other Loan Document by or on behalf of Citibank in its capacity as the Agent for the benefit of any Lender under any Loan Document (other than Citibank or an Affiliate of Citibank) and which is applied in accordance with the Loan Documents shall be deemed to be exempt from the requirements of Section 311 of the Trust Indenture Act pursuant to Section 311(b)(3) of the Trust Indenture Act.

In addition to, and without limitation of, any rights of the Lenders under Applicable Law, from and after the date that the Obligations have been accelerated pursuant to Section 8.2(a) or Section 8.2(b) (and for so long as such acceleration has not been rescinded by the Required Lenders), each Lender and each of its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by Applicable Law, to set-off and apply any and all deposits (including all account balances, whether general or special, time or demand, provisional or final and whether or not collected or available) at any time held, and any other Indebtedness or obligations (in whatever currency) at any time held or owing, by such Lender or any such Affiliate, to or for the credit or account of the Borrower against any and all of the Obligations of the Borrower now or hereafter existing under this Agreement or any other Loan Document to such Lender or its Affiliates, irrespective of whether or not such Lender or Affiliate shall have made any demand under this Agreement or any other Loan Document and although such Obligations of the Borrower may be contingent or unmatured or are owed to a branch, office or Affiliate of such Lender different from the branch, office or Affiliate holding such deposit or obligated on such indebtedness; provided that in the event that any Defaulting Lender exercises any such right of setoff, (x) all amounts so set off shall be paid over immediately to the Agent for further application in accordance with the provisions of Section 2.24 and, pending such payment, shall be segregated by such Defaulting Lender from its other funds and deemed held in trust for the benefit of the Agent, the LC Issuers, and the Lenders, and (y) the Defaulting Lender shall provide promptly to the Agent a statement describing in reasonable detail the Obligations owing to such Defaulting Lender as to which it exercised such right of setoff. The rights of each Lender and its Affiliates under this Section are in addition to other rights and remedies (including other rights of setoff) that such Lender or its Affiliates may have. Each Lender and LC Issuer agrees to notify the Borrower and the Agent promptly after any such setoff and application; provided that the failure to give such notice shall not affect the validity of such setoff and application.

Exposure held by the other Lenders so that after such purchase each Lender will hold its Pro Rata Share of the Aggregate Outstanding Credit Exposure. If any Lender, whether in connection with setoff or amounts which might be subject to setoff or otherwise, receives collateral or other protection for its Obligations or such amounts which may be subject to setoff, such Lender agrees, promptly upon demand, to take such action necessary such that all Lenders share in the benefits of such collateral ratably in proportion to their respective Pro Rata Shares of the Aggregate Outstanding Credit Exposure. In case any such payment is disturbed by legal process, or otherwise, appropriate further adjustments shall be made.

ARTICLE XII.

BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS

Section 12.1.Successors and Assigns. The terms and provisions of the Loan Documents shall be binding upon and inure to the benefit of the Borrower, the Agent and the Lenders and their respective successors and assigns permitted hereby, except that (a) the Borrower shall not have the right to assign its rights or obligations under the Loan Documents without the prior written consent of each Lender, (b) any assignment by any Lender must be made in compliance with Section 12.3, and (c) any transfer by participation must be made in compliance with Section 12.2. Any attempted assignment or transfer by any party not made in compliance with this Section 12.1 shall be null and void, unless such attempted assignment or transfer is treated as a participation in accordance with Section 12.3(c). The parties to this Agreement acknowledge that clause (b) of this Section 12.1 relates only to absolute assignments and this Section 12.1 does not prohibit assignments creating security interests, including any pledge or assignment by any Lender of all or any portion of its rights under this Agreement and any Note to a Federal Reserve Bank or any central bank having jurisdiction over such Lender; provided that no such pledge or assignment creating a security interest shall release the transferor Lender from its obligations hereunder unless and until the parties thereto have complied with the provisions of Section 12.3. The Agent may treat each Lender which made any Credit Extension or which holds any Note as the owner thereof for all purposes hereof unless and until such Lender complies with Section 12.3; provided that the Agent may in its discretion (but shall not be required to) follow instructions from the Lender which made any Credit Extension or which holds any Note to direct payments relating to such Credit Extension or Note to another Person. Any assignee of the rights to any Credit Extension or any Note agrees by acceptance of such assignment to be bound by all the terms and provisions of the Loan Documents. Any request, authority or consent of any Lender, who at the time of making such request or giving such authority or consent is the owner of the rights to any Credit Extension (whether or not a Note has been issued in evidence thereof), shall be conclusive and binding on any subsequent holder or assignee of the rights to such Credit Extension.

Section 12.2.Participations.

(a)Permitted Participants; Effect. Any Lender may at any time, without the consent of, or notice to, the Borrower, any LC Issuer, the Swing Line Lender or the Agent, sell participations to any Person (other than a natural Person, the Borrower or any of the Borrower's Affiliates or Subsidiaries or, unless an Event of Default has occurred and is continuing, (x) any competitor of the Borrower or any of its Subsidiaries or (y) any other company engaged in the business of selling or distributing energy products; provided that this clause (y) shall not apply to any financial institution solely as a result of such Person trading in commodity products) (each, a “Participant”) in all or a portion of such Lender's rights and/or obligationsunder this Agreement (including all or a portion of its Commitment and/or the Loans owing to it); provided that (i) such Lender's obligations under this Agreement and the other Loan Documents, if any, shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) such Lender shall remain the owner of its Outstanding Credit Exposure and the

- 82 -

holder of any Note issued to it in evidence thereof for all purposes under the Loan Documents and all amounts payable by the Borrower under this Agreement shall be determined as if such Lender had not sold such participating interest and (iv) the Borrower, the Agent, the LC Issuers and Lenders shall continue to deal solely and directly with such Lender in connection with such Lender's rights and obligations under this Agreement. For the avoidance of doubt, each Lender shall be responsible for the indemnity under Section 10.10 with respect to any payments made by such Lender to its Participant(s).

(b)Voting Rights. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve, without the consent of any Participant, any amendment, modification or waiver of any provision of this Agreement other than any amendment, modification or waiver with respect to any Credit Extension or Commitment in which such Participant has an interest which would require consent of all of the Lenders or all of the affected Lenders pursuant to the terms of Section 9.1.

(c)Benefit of Certain Provisions. The Borrower further agrees that each Participant shall be entitled to the benefits of Sections 3.1, 3.2, 3.4 and 3.5 (subject to the requirements and limitations therein, including the requirements under Section 3.5(g) (it being understood that the documentation required under Section 3.5(g) shall be delivered to the participating Lender)) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to Section 12.3; provided that such Participant (i) agrees to be subject to the provisions of Sections 2.19 and 3.7 as if it were an assignee under Section 12.3; and (ii) shall not be entitled to receive any greater payment under Section 3.1 or 3.5, with respect to any participation, than its participating Lender would have been entitled to receive, except to the extent such entitlement to receive a greater payment results from a Change in Law that occurs after the Participant acquired the applicable participation. Each Lender that sells a participation agrees, at the Borrower's request and expense, to use commercially reasonable efforts to require such Participant comply with the provisions of Sections 2.19 and 3.7 as if it were a Lender and to cooperate with the Borrower in enforcing such provisions against such Participant. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 11.1 as though it were a Lender; provided that such Participant agrees to be subject to Section 11.2 as though it were a Lender.

(d)Participant Register. Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant's interest in the Loans or other obligations under the Loan Documents (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant's interest in any commitments, loans, letters of credit or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such commitment, loan, letter of credit or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Agent (in its capacity as Agent) shall have no responsibility for maintaining a Participant Register.

Section 12.3.Assignments.

(a)Permitted Assignments. Any Lender (excluding for purposes of this Section 12.3(a), the Swing Line Lender or the LC Issuers) may at any time assign to one or more Eligible Assignees (such an assignee, a “Purchaser”) all or any part of its rights and obligations under the Loan Documents. The

- 83 -

parties to each assignment shall execute and deliver to the Agent an Assignment and Assumption Agreement. Each such assignment with respect to an Eligible Assignee which is not a Lender or an Affiliate of a Lender or an Approved Fund shall either be in an amount equal to the entire applicable Commitment and Outstanding Credit Exposure of the assigning Lender or (unless each of the Borrower and the Agent otherwise consents) be in an aggregate amount not less than $5,000,000. The amount of the assignment shall be based on the Commitment or Outstanding Credit Exposure (if the Commitment has been terminated) subject to the assignment, determined as of the date of such assignment or as of the “Trade Date,” if the “Trade Date” is specified in the assignment. Each partial assignment made by a Lender shall be made as an assignment of a proportionate part of all of such Lender's rights and obligations under this Agreement with respect to the Loans and Commitments assigned.

(b)Consents. The consent of the Agent, the Swing Line Lender and the LC Issuers (each such consent not to be unreasonably withheld or delayed) shall be required prior to an assignment becoming effective; provided that the consent of the Agent shall not be required for any assignment to a Person that is a Lender, an Affiliate of such Lender or an Approved Fund with respect to such Lender. The consent of the Borrower (such consent not to be unreasonably withheld or delayed) shall be required prior to an assignment becoming effective unless (i) such assignment is to a Lender, an Affiliate of a Lender or an Approved Fund or (ii) an Event of Default has occurred and is continuing; provided that the Borrower shall be deemed to have consented to any such assignment unless it shall object thereto by written notice to the Agent within fifteen (15) days after having received notice thereof. Any consent required under this Section 12.3(b) shall not be unreasonably withheld or delayed.

(c)Effect; Effective Date. Subject to acceptance and recording of the assignment by the Agent pursuant to Section 12.3(d), upon (i) delivery to the Agent of an Assignment and Assumption Agreement pursuant to Section 12.3(a), together with any consents required by Section 12.3(b), (ii) payment by the parties to the Assignment and Assumption Agreement (other than the Borrower) of a $3,500 fee to the Agent for processing such assignment (unless such fee is waived by the Agent) and (iii) delivery to the Borrower and the Agent of the documents required by Section 3.5, such Assignment and Assumption Agreement shall become effective on the effective date specified in such Assignment and Assumption Agreement. The Assignment and Assumption Agreement shall contain a representation and warranty by the Purchaser to the effect that none of the funds, money, assets or other consideration used to make the purchase and assumption of the Commitment and Outstanding Credit Exposure under the applicable assignment agreement constitutes “plan assets” as defined under ERISA and that the rights, benefits and interests of the Purchaser in and under the Loan Documents will not be “plan assets” under ERISA. On and after the effective date of such assignment, such Purchaser shall for all purposes be a Lender party to this Agreement and any other Loan Document executed by or on behalf of the Lenders and shall have all the rights, benefits and obligations of a Lender under the Loan Documents, to the same extent as if it were an original party thereto, and the transferor Lender shall be released with respect to the Commitment and Outstanding Credit Exposure assigned to such Purchaser without any further consent or action by the Borrower, the Lenders or the Agent. In the case of an assignment covering all of the assigning Lender's rights, benefits and obligations under this Agreement, such Lender shall cease to be a Lender hereunder but shall continue to be entitled to the benefits of, and subject to, those provisions of this Agreement and the other Loan Documents which survive payment of the Obligations and termination of the Loan Documents with respect to facts and circumstances occurring prior to the effective date of such assignment; provided that no assignment by a Defaulting Lender will constitute or effect a waiver or release of any claim of any party arising from such Lender being a Defaulting Lender. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 12.3 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with Section 12.2. Upon the consummation of any assignment to a Purchaser pursuant to this Section 12.3(c), the transferor Lender, the Agent and the Borrower shall, if the transferor

- 84 -

Lender or the Purchaser desires that its Loans be evidenced by Notes, make appropriate arrangements so that, upon cancellation and surrender to the Borrower of the Notes (if any) held by the transferor Lender, new Notes or, as appropriate, replacement Notes are issued to such transferor Lender, if applicable, and new Notes or, as appropriate, replacement Notes, are issued to such Purchaser, in each case in principal amounts reflecting their respective Commitments (or if the Aggregate Commitment has been terminated, their respective Outstanding Credit Exposure), as adjusted pursuant to such assignment.

(d)Register. The Agent, acting solely for this purpose as a non-fiduciary agent of the Borrower (and the Borrower hereby designates the Agent to act in such capacity), shall maintain at one of its offices in the United States a copy of each Assignment and Assumption Agreement delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amounts (and stated interest) of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, absent manifest error, and the Borrower, the Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(e)No Assignment to Certain Persons. No such assignment shall be made to (i) the Borrower or any of the Borrower's Affiliates or Subsidiaries, (ii) any Defaulting Lender or any of its Subsidiaries, or any Person who, upon becoming a Lender hereunder, would constitute any of the foregoing Persons described in this clause (ii) or (iii) unless an Event of Default has occurred and is continuing, (x) any competitor of the Borrower or any of its Subsidiaries or (y) any other company engaged in the business of selling or distributing energy products; provided that this clause (y) shall not apply to any financial institution solely as a result of such Person trading in commodity products.

(f)No Assignment to Natural Persons. No such assignment shall be made to a natural Person.

(g)Certain Additional Payments. In connection with any assignment of rights and obligations of any Defaulting Lender hereunder, no such assignment shall be effective unless and until, in addition to the other conditions thereto set forth herein, the parties to the assignment make such additional payments to the Agent in an aggregate amount sufficient, upon distribution thereof as appropriate (which may be outright payment, purchases by the assignee of participations or subparticipations, or other compensating actions, including funding, with the consent of the Borrower and the Agent, the applicable Pro Rata Share of Loans previously requested but not funded by the Defaulting Lender, to each of which the applicable assignee and assignor hereby irrevocably consent), to (x) pay and satisfy in full all payment liabilities then owed by such Defaulting Lender to the Agent, each LC Issuer, the Swing Line Lender and each other Lender hereunder (and interest accrued thereon), and (y) acquire (and fund as appropriate) its full pro rata share of all Loans and participations in Facility LCs and Swing Line Loans in accordance with its Pro Rata Share. Notwithstanding the foregoing, in the event that any assignment of rights and obligations of any Defaulting Lender hereunder becomes effective under Applicable Law without compliance with the provisions of this paragraph, then the assignee of such interest shall be deemed to be a Defaulting Lender for all purposes of this Agreement until such compliance occurs.

Section 12.4.Dissemination of Information. The Borrower authorizes each Lender to disclose to any Participant or Purchaser or any other Person acquiring an interest in the Loan Documents by operation of law (each a “Transferee”) and any prospective Transferee any and all information in such Lender's

- 85 -

possession concerning the creditworthiness of the Borrower and its Subsidiaries; provided that each Transferee and prospective Transferee agrees to be bound by Section 9.12.

Section 12.5.Tax Certifications. If any interest in any Loan Document is transferred to any Transferee which is not incorporated under the laws of the United States or any State thereof, the transferor Lender shall cause such Transferee, concurrently with the effectiveness of such transfer, to comply with the provisions of Section 3.5.

Section 12.6.No Liability of General Partner. It is hereby understood and agreed that the General Partner shall have no personal liability, as general partner or otherwise, for the payment of any amount owing or to be owing hereunder or under the other Loan Documents. The Agent and the Lenders agree for themselves and their respective successors and assigns that no claim arising against the Borrower under any Loan Document with respect to the Obligations shall be asserted against the General Partner (in its individual capacity).

ARTICLE XIII.

CHOICE OF LAW; CONSENT TO JURISDICTION; WAIVER OF JURY TRIAL

Section 13.1.CHOICE OF LAW. UNLESS OTHERWISE EXPRESSLY SET FORTH THEREIN, THE LOAN DOCUMENTS SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

Section 13.2.CONSENT TO JURISDICTION. THE BORROWER, THE AGENT AND EACH LENDER HEREBY IRREVOCABLY SUBMITS TO THE EXCLUSIVE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK SITTING IN NEW YORK COUNTY AND OF THE UNITED STATES DISTRICT COURT OF THE SOUTHERN DISTRICT OF NEW YORK, AND ANY APPELLATE COURT FROM ANY THEREOF, IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO ANY LOAN DOCUMENTS AND THE BORROWER, THE AGENT AND EACH LENDER HEREBY IRREVOCABLY AGREES THAT ALL CLAIMS IN RESPECT OF SUCH ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED IN ANY SUCH COURT AND IRREVOCABLY WAIVES ANY OBJECTION IT MAY NOW OR HEREAFTER HAVE AS TO THE VENUE OF ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN SUCH A COURT OR THAT SUCH COURT IS AN INCONVENIENT FORUM. NOTHING HEREIN SHALL LIMIT THE RIGHT OF THE AGENT OR ANY LENDER TO BRING PROCEEDINGS AGAINST THE BORROWER IN THE COURTS OF ANY OTHER JURISDICTION. ANY JUDICIAL PROCEEDING BY THE BORROWER AGAINST THE AGENT OR ANY LENDER INVOLVING, DIRECTLY OR INDIRECTLY, ANY MATTER IN ANY WAY ARISING OUT OF, RELATED TO, OR CONNECTED WITH ANY LOAN DOCUMENT SHALL BE BROUGHT ONLY IN A COURT IN NEW YORK, NEW YORK.

Section 13.3.WAIVER OF JURY TRIAL. THE BORROWER, THE AGENT AND EACH LENDER HEREBY WAIVE TRIAL BY JURY IN ANY JUDICIAL PROCEEDING INVOLVING, DIRECTLY OR INDIRECTLY, ANY MATTER (WHETHER SOUNDING IN TORT, CONTRACT OR OTHERWISE) IN ANY WAY ARISING OUT OF, RELATED TO, OR CONNECTED WITH ANY LOAN DOCUMENT OR THE RELATIONSHIP ESTABLISHED THEREUNDER.

The credit rating in effect on any date for the purposes of this Pricing Schedule is that in effect at the close of business on such date. The Borrower shall at all times maintain a Designated Rating from at least one of Moody's, Fitch and S&P. If at any time the Borrower does not have a Designated Rating from any of Moody's, Fitch or S&P, Level V Status shall exist.

Notwithstanding the foregoing, (i) if the Designated Ratings are split and all three ratings fall in different levels, the Applicable Margin and the Applicable Fee Rate shall be based upon the level indicated by the middle rating; (ii) if the Designated Ratings are split and two of the ratings fall in the same level (the “Majority Level”) and the third rating is in a different level, the Applicable Margin and the Applicable Fee Rate shall be based upon the Majority Level; (iii) if only two of the three Rating Agencies issue a Designated Rating, the higher of such ratings shall apply, provided that if the higher rating is two or more levels above the lower rating, the rating next below the higher of the two shall apply; (iv) if only one of the three Rating Agencies issues a Designated Rating, such rating shall apply; and (v) if the Designated Rating established by S&P, Moody's or Fitch shall be changed (other than as a result of a change in the rating system of S&P, Moody's or Fitch), such change shall be effective as of the date on which it is first announced by the applicable Rating Agency. If the rating system of S&P, Moody's or Fitch shall change, or if any of S&P, Moody's or Fitch shall cease to be in the business of rating corporate debt obligations, the Borrower and the Agent shall negotiate in good faith if necessary to amend this provision to reflect such changed rating system or the unavailability of Designated Ratings from such Rating Agencies and, pending the effectiveness of any such

amendment, the Applicable Margin and the Applicable Fee Rate shall be determined by reference to the Designated Rating of such Rating Agency most recently in effect prior to such change or cessation.
