	(C)		an amount equal to any accounts payable attributable to the period prior to the Effective Time of any Seller or any of its Affiliates (including any of the Companies) that were paid on or after the Effective Time by Buyer or any Company (excluding only accounts payable referred to in Section 1.3(a)(i)(D) and accounts payable being disputed (in good faith) by Sellers, the Companies or their Affiliates);
	(D)		the amount, if any, by which: (I) the aggregate of all payments received or to be received by Sellers or their Affiliates (other than the Companies) in accordance with the Seller Hedges and the

	(I)		the amount of $233,000 attributable to anticipated upgrades to the Gregory Plant cooling project.

(iii)

increased or decreased as otherwise mutually agreed upon by Sellers and Buyer.

     (b) No later than ten Business Days prior to the Closing Date, Sellers will prepare and submit to Buyer a statement setting forth, in reasonable detail, Sellers’ good faith and reasonable computation of the estimated adjustments to the Purchase Price described in Section 1.3(a), as applicable. Sellers will furnish to Buyer, together with such computation, copies of back-up and other supporting information and such other documentation as Buyer may reasonably request that

reasonably supports such computation. Buyer will have three Business Days after receipt of Sellers’ statement to review such statement. If Buyer fails to give notice of objection within the three Business Day period, then Sellers’ statement will be used for the purpose of determining the Adjusted Purchase Price. If Buyer, in good faith, objects to any portion of such statement, it will notify Seller in writing (setting forth, in reasonable detail, the reasons for such objections and, to the extent reasonably determinable by Buyer, Buyer’s computation of the adjustments to the Purchase Price) within three Business Days of receipt of Sellers’ statement and Buyer and Sellers will endeavor in good faith to resolve any disputed matters prior to Closing. If Buyer and Sellers resolve all disputed matters prior to the Closing Date, the Adjusted Purchase Price at Closing will be that mutually agreed amount. If Buyer and Sellers are unable to so resolve all disputed matters prior to Closing, the Adjusted Purchase Price at Closing will be based on Sellers’ statement (including any amount still being disputed by Buyer, which is the “Disputed Amount”) and any further adjustments and the resolution of the Disputed Amount will be made only in accordance with Section 1.3(c). At least one Business Day prior to the Closing Date, Sellers will notify Buyer in writing of the allocation of the Adjusted Purchase Price between Sellers and wiring instructions for payment. The Adjusted Purchase Price will be paid to Sellers at Closing in immediately available funds by confirmed wire transfer to a bank account or accounts designated by Sellers.

     (c) Within 90 days after the Closing Date, Buyer will cause to be prepared and delivered to Sellers a statement (the “Final Settlement Statement”) setting forth the amount of the final adjustments to the Purchase Price determined reasonably and in good faith in accordance with Section 1.3(a) (together with supporting documentation used by Buyer in calculating each such amount and otherwise in preparing the Final Settlement Statement and such other documentation as Sellers may reasonably request). Sellers will cooperate in good faith with Buyer in the preparation of the Final Settlement Statement, and will promptly, but in any event within 10 days after request, provide Buyer with, or access to, all documentation in Sellers’ or its Affiliates’ (other than the Companies’) possession related to the Final Settlement Statement reasonably requested by Buyer. Within 30 days after the Final Settlement Statement is delivered to Seller, Seller will complete its examination thereof and may deliver to Buyer a written report setting forth in reasonable detail any objections or, to the extent reasonably determinable by Sellers, proposed adjustments to the Final Settlement Statement (the “Objection Notice”). Any objections or proposed adjustments that are not included in a proper Objection Notice delivered to Buyer within 30 days after Sellers’ receipt of the Final Settlement Statement are irrevocably waived and released by Sellers. Sellers and Buyer will each use Reasonable Efforts to resolve any objections to the Final Settlement Statement as described in the Objection Notice. If final resolution of such objections is not obtained within 30 days following the delivery of the Objection Notice, Sellers and Buyer will refer any unresolved objections to the Referral Firm for its resolution. The resolution by the Referral Firm will be binding on Sellers and Buyer, and will be final and non-appealable. Sellers will bear 50%, and Buyer will bear 50%, of the fees and expenses of the Referral Firm.

     (d) Upon the resolution of the adjustments to the Purchase Price in accordance with Section 1.3(c) (whether by agreement of Sellers and Buyer (including Sellers’ failure to timely deliver an Objection Notice) or as determined by the Referral Firm), the amount of the Purchase Price as so adjusted will be the “Post-Closing Adjusted Purchase Price.” Within three Business Days after the determination of the Post-Closing Adjusted Purchase Price: (i) Buyer will tender to

Sellers cash equal to the aggregate positive excess of the Post-Closing Adjusted Purchase Price over the Adjusted Purchase Price or (ii) Sellers will, jointly and severally, tender to Buyer cash equal to the aggregate positive excess of the Adjusted Purchase Price over the Post-Closing Adjusted Purchase Price. Upon the resolution of the adjustments to the Purchase Price in accordance with Section 1.3(c) (whether by agreement of Sellers and Buyer (including Sellers’ failure to timely deliver the Objection Notice) or as determined by the Referral Firm), there will be no further adjustments to the Purchase Price (or Post-Closing Adjusted Purchase Price), except to the extent, and for the purposes, provided in Section 11.9 and with respect to Taxes as provided in Section 8.7.

     Section 3.2 Organization and Standing. Each Seller is duly organized, validly existing and in good standing under the laws of the State of Delaware.

This Agreement has been duly executed and delivered by each Seller and constitutes, and each other agreement, instrument, or document executed or to be executed by such Seller in connection with the transactions contemplated hereby has been, or when executed will be, duly executed and delivered by such Seller and constitutes, or when executed and delivered will constitute, a valid and legally binding obligation of such Seller, enforceable against such Seller in accordance with their respective terms, except as such enforceability may be limited by bankruptcy, insolvency, moratorium or other laws affecting or relating to the enforcement of creditors’ rights generally and the application of general principles of equity (regardless of whether that enforceability is considered in a proceeding at law or in equity).

     Section 3.4 Non-Contravention. Except as set forth in Section 3.4 of the Disclosure Schedule, the execution, delivery, and performance by each Seller of this Agreement and each other agreement, instrument, or document executed or to be executed by such Seller in connection with the transactions contemplated by this Agreement to which such Seller is a party and the consummation by such Seller of the transactions contemplated hereby and thereby (i) do not and will not conflict with or result in a violation of any provision of, or constitute (with or without the giving of notice or the passage of time or both) a default under, or give rise (with or without the giving of notice or the passage of time or both) to any right of termination, cancellation, or acceleration under, any bond, debenture, note, mortgage or indenture, or any material contract, agreement, or other material instrument or obligation to which a Seller is a party or by which a Seller or any of a Seller’s properties may be bound, or (ii) do not or will not materially violate any Applicable Law binding upon a Seller.

     Section 3.5 Approvals. Except in connection with the HSR Act or as provided in the Credit Facilities, in Section 8.20 of this Agreement, or in Section 3.5 of the Disclosure Schedule, no consent, approval, order, or authorization of, or declaration, filing, or registration with, any Governmental Entity or of any third Person is required to be obtained or made by Seller in connection with the execution, delivery, or performance by Seller of this Agreement, each other agreement, instrument, or document executed or to be executed by Seller in connection with the transactions contemplated hereby to which Seller is a party or the consummation by Seller of the transactions contemplated hereby and thereby.

Sellers believe that the Adjusted Purchase Price payable by Buyer for the Interests and Assigned Assets pursuant to this Agreement represents a fair value of the Companies and Assigned Assets as a going concern. Sellers have considered alternative proposals and have engaged in discussions with others concerning the potential sale of the Interests and Assigned Assets, and the Adjusted Purchase Price represents a fair value for a sale of the Interests and Assigned Assets, based upon the factors considered by Sellers.

     Section 8.5 Notification of Certain Matters.

     (a) Sellers will give prompt notice to Buyer of: (i) the occurrence or nonoccurrence of any event the occurrence or nonoccurrence of which is reasonably expected to cause any representation or warranty made by such Seller in Article III or Article IV to be untrue at or prior to the Closing of which Sellers have Knowledge, (ii) any discovery that any representation or warranty of Sellers in Articles III and IV is untrue, and (iii) any failure of such Seller or any Company to comply with or satisfy any covenant, condition, or agreement to be complied with or satisfied by such Seller or any Company hereunder prior to Closing.

     (b) The delivery of any notice or of any supplements or amendments to the Disclosure Schedule pursuant to this Section will not be deemed to: (i) modify the representations or warranties hereunder of the party delivering such notice, (ii) modify the conditions set forth in Article IX or (iii) limit or otherwise affect the remedies (if any) available under this Agreement to the party receiving such notice; provided, however, that if the Closing occurs, the Disclosure Schedule as so supplemented or amended as of the Closing with respect to such Post-Signing Event will be deemed to be the Disclosure Schedule for purposes of determining whether or not any breach of the representations and warranties of any Company has occurred.

     Section 8.6 Employee Matters.

     (a) Conditioned upon the Closing, Buyer will make offers of employment to each of the “Offered Employees” and may make offers of employment to any of the “Additional Employees” (each as defined below) that meet the requirements under this Section 8.6. Buyer: (i) must make such offers of employment to the Offered Employees within 15 Business Days after the date of this Agreement, and (ii) will make offers of employment to those Additional Employees Buyer elects to offer employment by the date mutually agreed by Sellers and Buyer (the applicable date being the “Offer Date”). Within 20 Business Days after the date of this Agreement, Buyer will conclude interviews of Additional Employees and will notify Sellers in writing of the Additional Employees (if any) whom Buyer desires to employ. Sellers and Buyer will then mutually agree as to the date when Buyer may extend offers to those Additional Employees. Each offer to an Offered Employee and an Additional Employee must include base wages equal to or greater than those currently in effect for that employee and comparable benefits (determined, in each case, based on the written disclosures provided to Buyer) at least as favorable in the aggregate to those currently in effect for each employee. The Offered Employees and Additional Employees must be provided at least five days to accept the offers. Buyer will notify Sellers in writing of the names of those Crosstex Energy employees who: (i) received offers of employment, (ii) accepted the offers and (iii) rejected the offers, in each case no later than five days after the expiration of the five-day period allowed to accept the offers. As of the Closing Date, Crosstex Energy will terminate and Buyer will hire those Offered Employees and Additional Employees accepting the offers at the compensation levels and with benefits and terms and conditions of employment required by this Section 8.6 (the “Transferred Employees”).

     (b) For purposes of this Section 8.6, “Offered Employees” and “Additional Employees” mean the Crosstex Energy employees so designated in Section 4.16 of the Disclosure Schedule.

     (c) Buyer must recognize the service that Crosstex Energy credits to each Transferred Employee in accordance with Crosstex Energy policies through the Closing Date as disclosed to Buyer in writing prior to the Closing for purposes of determining the number of vacation days and sick leave days to which each Transferred Employee will be entitled upon commencing employment with Buyer, eligibility to participate and vesting under all employee benefit plans and programs of Buyer or its Affiliates for which the Transferred Employees are eligible, eligibility for earlier than normal retirement and similar rights to commence benefits under any pension plan offered to Transferred Employees, and eligibility for retiree welfare benefits. To the extent permitted by Buyer’s plans, Buyer will offer each Transferred Employee medical insurance without any exclusions for pre-existing conditions.

     (d) Except as expressly provided in this Section 8.6, from the period beginning on the date of this Agreement and ending on the first anniversary of the date of this Agreement, Buyer and its Affiliates will not solicit, raid, encourage, entice or induce, directly or indirectly, any employee (or person who was an employee within the previous three months) of Sellers or their Affiliates or any other person who is under contract with or rendering services to Sellers or their Affiliates in an employee-like capacity in the day-to-day business operations of Sellers or their Affiliates, to (i) terminate his employment by, or contractual relationship with, Sellers or their Affiliates, (ii) refrain from extending or renewing the same (upon the same or new terms), (iii) refrain from rendering services to or for Sellers or their Affiliates, (iv) become employed by or to enter into contractual relations with any Persons other than Sellers or their Affiliates, or (v) enter into an employment or contractual relationship with a competitor of Sellers or their Affiliates; provided that, Buyer is not prohibited from utilizing a contractor that performs work for Persons other than Sellers and its Affiliates to the extent that such use does not in any manner interfere with Sellers’ or its Affiliates’ utilization of such contractor. From the period beginning on the date of this Agreement and ending on the first anniversary of the date of this Agreement, Sellers and their Affiliates will not solicit, raid, encourage, entice or induce, directly or indirectly, any employee (or person who was an employee within the previous three months) of Buyer or Buyer’s Affiliates (for the purposes of this sentence, after the Effective Time, Buyer’s Affiliates includes each Company) or any other person who is under contract with or rendering services to Buyer or any of its respective Affiliates in an employee-like capacity in the day-to-day business operations of Buyer or any of its Affiliates to (i) terminate his employment by, or contractual relationship with, Buyer or any of its Affiliates, (ii) refrain from extending or renewing the same (upon the same or new terms), (iii) refrain from rendering services to or for Buyer or any of its Affiliates, (iv) become employed by or to enter into contractual relations with any Persons other than Buyer or any of its Affiliates, or (v) enter into an employment or contractual relationship with a competitor of Buyer or any of its Affiliates. The restrictions set forth in this Section 8.6(d) will not apply to general solicitations by Buyer or Seller which are not directed at a specific individual. The covenants and undertakings contained in this Section 8.6(d) relate to matters which are of a special, unique and extraordinary character and a violation of any of the terms of this Section 8.6(d) will cause irreparable injury to the parties, the amount of which will be impossible to estimate or determine and which cannot be adequately compensated. Therefore, without the necessity of proving actual damages, the non-breaching party will be entitled to an

injunction, restraining order or other equitable relief from any court of competent jurisdiction in the event of any breach of this Section 8.6(d). The rights and remedies provided by this Section 8.6(d) are cumulative and in addition to any other rights and remedies which Sellers and Buyer may have under this Agreement or at law or in equity.

     (e) Within sixty (60) days following the Closing Date, Sellers will deliver to Buyer a list of the deductible expenses paid by each Transferred Employee under medical, dental and vision plans of Sellers or its Affiliates during the current plan year up to the Closing Date and the maximum deductible under that plan (the “Deductible Notice”). From and after the Closing Date through December 31, 2009, Buyer will reimburse each Transferred Employee for any and all amounts paid by such Transferred Employee that exceed the maximum deductible identified for such Transferred Employee on the Deductible Notice; provided, that the Transferred Employee provides to Buyer the explanation of benefits sent to them by their insurance provider as proof of such payment. This Section 8.6(e) does not obligate Buyer to reimburse a Transferred Employee for coinsurance or maximum out-of-pocket amounts.

     (f) If, within one year after the Closing Date, Buyer terminates (for any reason other than for good cause) or a Transferred Employee terminates her employment because she is transferred to a different work location greater than forty miles from her location immediately preceding Closing or her salary or other compensation is reduced, Buyer will pay to that Transferred Employee severance benefits in an amount calculated in accordance with Exhibit C. Regardless of any other provision in this Agreement, each Transferred Employee is intended to be a third party beneficiary with respect to, and will have the right to directly enforce, this Section 8.6.

     (g) If, within one year after the Closing Date, Buyer hires as an employee, or on a contract or consulting basis, any Offered Employee or Additional Employee that did not accept Buyer’s offer of employment pursuant to Section 8.6(a) (or, in the case of Additional Employees, that did not receive an offer of employment from Buyer), Buyer will pay to Sellers an amount equal to the severance benefits calculated in accordance with Section 8.6(f) as if such employee has been employed by Buyer and became entitled to severance benefits pursuant to Section 8.6(f).

     (h) Crosstex Energy will be responsible for discharging all obligations under the Worker Adjustment and Retraining Notification Act (29 U.S.C. § 2101, et seq.) (“WARN Act”) and similar applicable local laws for the notification of Offered Employees and Additional Employees of any “employment loss” within the meaning of the WARN Act and similar applicable local law which occurs prior to the Closing Date. Buyer acknowledges that it has not informed Crosstex Energy of any planned or contemplated decisions or actions by Buyer that would require the service of notice under the WARN Act. Buyer agrees that it will not take, or omit to take, any action that causes the notice provisions of the WARN Act to be applicable to the transactions contemplated by this Agreement; provided that Crosstex Energy will provide Buyer at Closing with a list of employees assigned to the Midstream Assets who have been terminated or notified of their termination during the sixty-day period ending on the Closing Date.

     (i) Crosstex Energy will be responsible for offering applicable health care continuation coverage (at the employee’s expense) with respect to Offered Employees and Additional Employees who terminate employment with Crosstex Energy on or before the Closing Date.

     Section 8.7 Taxes.

     (a) Sellers acknowledge that the Companies are disregarded entities for federal Tax purposes. Accordingly, Buyer and Sellers intend that the sale of the Interests will be treated for federal Tax purposes as a taxable sale of the Companies’ assets (including the Assigned Assets) for the Adjusted Purchase Price and the assumption of liabilities of the Companies. Buyer will be responsible and, as applicable, cause the Companies to pay, and Buyer agrees to hold harmless and indemnify Sellers, for any and all (i) Transfer Taxes, and (ii) Taxes of the Companies (and those attributable to the Assigned Assets) for all Post-Closing Straddle Periods and all tax periods beginning at or after the Effective Time. Sellers shall be jointly and severally responsible, and agree to hold harmless and indemnify Buyers and the Companies, for (i) Taxes of the Companies (and those attributable to the Assigned Assets) for all Pre-Closing Tax Periods, except as adjusted in Section 1.3(a)(ii)(B), (ii) all Taxes of the Companies (and those attributable to the Assigned Assets) for all Pre-Closing Straddle Periods, except as adjusted in Section 1.3(a)(ii)(B), and (iii) all Transaction Taxes. Buyer and Sellers agree not to take any position with respect to Taxes inconsistent with the intended tax treatment of this transaction and the provisions of this Section 8.7.

     (b) Sellers will prepare and timely file, or cause to be prepared and timely filed, all Tax Returns of the Companies that are required to be filed after the Effective Time with respect to any Pre-Closing Tax Period (the “Pre-Closing Returns”). Sellers will pay or cause to be paid all Taxes imposed on the Company shown as due and owing on such Pre-Closing Returns and any amendments to such Tax Returns, except to the extent any such Taxes are taken into account in determining the Adjusted Purchase Price pursuant to Section 1.3. Sellers will prepare or cause to be prepared the respective Pre-Closing Returns consistently with the most recent customs and practices of the Company, unless otherwise by Applicable Law. Within a reasonable period of time prior to filing a Pre-Closing Return that might affect Buyer or a Company for any taxable period ending after the Effective Time, Sellers will furnish a copy of such Pre-Closing Return to Buyer.

     (c) Buyer will prepare or cause to be prepared any Tax Return covering a Straddle Period that is required to be filed after the Effective Time with respect to any of the Companies (the “Straddle Period Returns”) consistently with the most recent customs and practices of the Company (or its Affiliate, as applicable), unless otherwise required by Applicable Law. Within a reasonable period of time prior to the due date (including extensions) of any Straddle Period Return, Buyer will furnish a copy of such Straddle Period Return to Sellers, together with a request for Sellers’ payment to Buyer of the amount of Taxes attributable to the Pre-Closing Straddle Period and reasonable supporting documentation. If Sellers have no objections to the content of the Straddle Period Return, Sellers will pay Buyer the amount requested. Buyer will thereafter pay such amount to the Governmental Entity to which the Taxes are owed and provide reasonable documentation to Sellers confirming such payments within ten (10) days of the dates of such payments. Sellers will notify Buyer in writing of the existence of any comments or objections (specifying in reasonable detail the nature and basis of such comments or objections) of Sellers to any items set forth on the draft Straddle Period Return for the Company (a “Tax Dispute Notice”). Buyer and Sellers will consult and resolve in good faith any such objection. If Buyer and Sellers, notwithstanding such good faith effort, fail to resolve the dispute within thirty (30) days after the Tax Dispute Notice was delivered to Buyer, then Sellers and Buyer will submit such dispute to the Referral Firm. The resolution of the Referral Firm will be binding on Sellers

and Buyer, and will be final and non-appealable. Sellers will bear 50%, and Buyer will bear 50%, of the fees and expenses of the Referral Firm. Notwithstanding the foregoing, the terms and provisions of this Section 8.7(c) will not prohibit Buyer from timely filing the Straddle Period Returns, but Buyer will file, or cause to be filed, an amended Straddle Period Return to the extent necessary to reflect the applicable parties’ agreed resolution of the objections contained in the Tax Dispute Notice or the determination of the Referral Firm after the original filing due date.

     (d) For purposes of allocating Taxes of the Company between that portion of the Straddle Period ending prior to the Effective Time (the “Pre-Closing Straddle Period”) and that portion of the Straddle Period beginning at the Effective Time (the “Post-Closing Straddle Period”), the portion of such Taxes related to the Pre-Closing Straddle Period will be deemed to be: (i) in the case of Taxes (other than income Taxes, franchise and margin Taxes, Taxes measured in whole or in part by reference to gross revenues or receipts, income, excise, employment, withholding, gross receipts and other similar Taxes and sales and use Taxes), equal to the amount of such Taxes for the entire Straddle Period multiplied by a fraction the numerator of which is the number of days during the Straddle Period that are in the Pre-Closing Straddle Period and the denominator of which is the number of days in the Straddle Period, provided that Sellers will not be required to pay any Taxes to the extent such Taxes were taken into account in determining the Adjusted Purchase Price pursuant to Section 1.3; and (ii) in the case of income Taxes, franchise and margin Taxes, Taxes measured in whole or in part by reference to gross revenues or receipts, income, excise, employment, gross receipts and other similar Taxes and sales and use Taxes, will be allocated between the Pre-Closing Straddle Period and the Post-Closing Straddle Period as though the taxable year of the Company terminated based on interim closing of the books as of the Effective Time, and based on accounting methods, elections and conventions that do not have the effect of distorting income and expenses. All determinations necessary to give effect to the foregoing allocations will be made in a manner consistent with the past practice of the Company with respect to such items, unless otherwise required by Applicable Law.

     (e) Buyer will notify each Seller promptly after receipt by Buyer or any Affiliate of Buyer of written notice of any inquiries, claims, assessments, audits or similar events with respect to Taxes relating to a Pre-Closing Tax Period or Straddle Period for which a Seller may be liable under this Agreement (any such inquiry, claim, assessment, audit or similar event, a “Tax Matter”). Sellers, at their own expense, will have the exclusive authority to represent the interests of the Company for any Pre-Closing Tax Period with respect to any Tax Matter before the IRS or any other Governmental Entity involving the Company and will have the sole right to control the defense, compromise or other resolution of such Tax Matters, including responding to inquiries, filing Tax Returns and settling audits. Buyer will execute or cause to be executed powers of attorney or other documents necessary to enable Sellers to take all actions desired by Sellers with respect to such Tax Matters, but only with respect to Pre-Closing Tax Periods. Sellers may in their sole discretion pursue or forego any and all administrative appeals, proceedings, hearings and conferences with any Governmental Entity with respect to such Tax Matter for any Pre-Closing Tax Period, and subject to Section 8.7(g), may initiate any claim for refund, file any amended return, or take any other action which is deemed appropriate by Sellers with respect to such Tax Matter, but only with respect to Pre-Closing Tax Periods. Sellers will keep Buyer fully and timely informed with respect to the commencement, status and nature of any Tax Matter over which Sellers have such exclusive authority. Notwithstanding the foregoing,

Sellers and Buyer will jointly control all proceedings in connection with any Tax Claim relating solely to Taxes for a Straddle Period, and will equally bear and pay costs and expenses related to such proceedings. No party will settle a Tax Matter relating solely to Taxes of the Companies for a Straddle Period without the other party’s prior written consent (which consent may not be unreasonably withheld, conditioned or delayed; and which consent will be considered to be unreasonably withheld if such settlement has no adverse effect on the other party).

     (f) Buyer and its Affiliates (including after the Closing, the Companies), on the one hand, and Sellers, on the other hand, will cooperate with each other in contesting any Tax Matter, which cooperation will include, without limitation, the retention and, at the contesting party’s request and expense, the provision of records and information which are reasonably relevant to such Tax Matter, and making employees available on a mutually convenient basis to provide additional information or explanation of any material provided hereunder or to testify at proceedings relating to such Tax Matter.

     (g) Sellers will not file or cause or permit to be filed any amended Tax Return for any Pre-Closing Tax Periods for any Company that may affect the Tax liability of Buyer or the Company for any Post-Closing Tax Period or Straddle Period without providing written notification to Buyer a reasonable time prior to filing such amended Tax Return and with due consideration to any timely comments received from Buyer in response to that notice. Buyer will not file or cause to be filed any amended Tax Returns covering any period or adjusting any Taxes for a period with respect to a Company which includes (i) any Pre-Closing Tax Period without the prior written consent of Sellers, which may be withheld in Sellers’ sole discretion, or (ii) a Straddle Period without the prior written consent of Sellers, which may not be unreasonably withheld or delayed.

     (h) Any refund or credits of Taxes paid or payable that are attributable to the Companies for any Pre-Closing Tax Period or any Pre-Closing Straddle Period will be for the account of Sellers. Any refunds or credits of Taxes paid or payable that are attributable to the Companies for any other taxable period will be for the account of Buyer. Buyer, if Sellers so request and at Sellers’ expense, will cause the Companies to file for and obtain any refunds or credits to which Sellers are entitled. Buyer will cause the Companies to forward to Sellers any such refund within ten (10) days after the refund is received (or reimburse Sellers for any such credit within ten (10) days after the credit is applied against another Tax liability); provided, however, that Sellers will indemnify Buyer for any amount paid pursuant to this Section 8.7(h) if any such refund or credit is subsequently disallowed.

     (i) The Adjusted Purchase Price (together with the liabilities of the Companies assumed by Buyer) will be allocated among the Companies’ assets (including the Assigned Assets) in accordance with Section 1060 of the Code and the Treasury regulations thereunder (and any similar provision of state or local law, as appropriate) (the “Allocation”). Buyer will provide a proposed Allocation to Sellers in writing at least fifteen (15) days prior to Closing, and thereafter Buyer and Sellers will act in good faith and reasonably cooperate with each other to agree on the final Allocation prior to the Closing. If said Allocation is agreed upon, Sellers and Buyer will report the transactions contemplated hereby on all Tax Returns, including, but not limited to Form 8594, in a manner consistent with the Allocation as adjusted to properly reflect the Post-Closing Adjusted Purchase Price. If, contrary to the intent of Sellers and Buyers as expressed in this Section 8.7(i) any Taxing authority makes or proposes an allocation different

from the Allocation determined under this Section 8.7(i), Sellers and Buyer will cooperate with each other in good faith to contest such Taxing authority’s allocation (or proposed allocation); provided, however, that, after consultation with the party (or parties) adversely affected by such allocation (or proposed allocation), the other party (or parties) hereto may file such protective claims or Tax Returns as may be reasonably required to protect its (or their) interests.

     (j) Sellers and Buyer agree to furnish to each other at Closing or as soon thereafter as practicable any and all information and documents reasonably required to comply with Tax and financial reporting requirements and audits.

     (k) Sellers will be jointly and severally liable for all (i) Taxes that are imposed on the Company and/or its assets and businesses and Taxes that are attributable to the ownership or operation of the Midstream Assets and the Assigned Assets, in each case to the extent such Taxes are attributable to the operations of such businesses or the ownership of such assets during any taxable year ending prior to the Effective Time, except for those Taxes that are included in the Adjusted Purchase Price pursuant to the Final Settlement Statement, (ii) Taxes that are imposed on the Company and/or its assets and businesses, and Taxes which are attributable to the ownership or operation of the Midstream Assets and the Assigned Assets, in each case to the extent such Taxes are attributable to the operations of such businesses or the ownership of such assets during the portion of any Straddle Period ending prior to the Effective Time (determined in the manner specified in Section 8.7(d)), except for those Taxes that are included in the Adjusted Purchase Price pursuant to the Final Settlement Statement, (iii) all Transaction Taxes, and (iv) all Tax liabilities of Crosstex DC Gathering Company, J.V. regardless of whether incurred before or after the Closing Date.

     (l) To the extent the ad valorem, property or similar Taxes taken into account in determining the Post-Closing Adjusted Purchase Price exceed the actual amount of said Taxes payable for the Pre-Closing Straddle Period, Buyer will cause the Companies to pay said excess amount to Sellers within ten (10) days after the actual amount of said Taxes allocable to the Pre-Closing Straddle Period is determined. To the extent the ad valorem, property or similar Taxes taken into account in determining the Post-Closing Adjusted Purchase Price are less than the actual amount of said Taxes payable for the Pre-Closing Straddle Period, Sellers will pay the amount of the shortfall to Buyer within ten (10) days after the actual amount of said Taxes allocable to the Pre-Closing Straddle Period is determined.

     (m) Sellers shall cause each of Javelina Marketing, Javelina NGL and any newly-formed entity that will become a “Company” by virtue of Section 8.15 to obtain a Texas tax identification number prior to the Effective Time and furnish such information to Buyer at Closing.

     Section 8.8 Fees and Expenses. All fees and expenses incurred in connection with this Agreement by Sellers and the Companies will be borne by and paid by Sellers, regardless of whether or not the transactions contemplated hereby are consummated. All amounts due and owing Goldman, Sachs & Co. by Sellers and/or Companies in respect of the transactions hereunder will be borne by and paid by Sellers. All expenses incurred in connection with this Agreement by Buyer will be borne by and paid by Buyer, regardless of whether or not the transactions contemplated hereby are consummated.

     Section 8.9 Public Announcements. If Buyer or Sellers desire to issue any press release or make any statement to the public generally with respect to this Agreement or the transactions contemplated hereby, the party desiring to issue a release or make a statement will obtain the prior consent of the other party (except as otherwise provided in this Section 8.9). If Buyer or Sellers request consent to issue a press release or make a public statement, the party receiving the request will not unreasonably withhold or delay the consent, if the consent is given verbally, the consenting party will confirm it in writing within one Business Day after verbally consenting. Regardless of the foregoing, however, any party to this Agreement may make any public disclosure it believes in good faith is required by Applicable Law, the rules of any exchange upon which its securities are publicly traded, or any listing or trading agreement concerning its publicly traded securities (in which case, if Buyer is the disclosing party, it will advise Sellers, and if any Seller or a Company is the disclosing party, Sellers will advise Buyer, in each instance before making the disclosure and will provide the other, to the extent practicable, with a reasonable opportunity to comment on such proposed disclosures).

     Section 8.10 Books and Records. At or as soon as reasonably practicable after Closing, Sellers will deliver to Buyer all records of the Companies that are in Sellers’ control, including original minute books and other corporate books and records and accounts, policies of insurance, real property, equipment, materials and service contracts, Permits, and all regulatory, environmental, tariff, financial, audit, and tax data, records, reports, returns, filings, notices, correspondence, memoranda, and other information (in physical or digital form), including all documents supporting such reports, returns, filings, correspondence and memoranda, but exclusive of any Sales Information; provided that those books and records will not include historical financial and Tax information that is reported by Sellers or an Affiliate other than the Companies. Upon Buyer’s reasonable written request at any time prior to the first anniversary of the Closing Date, Sellers further agree to provide Buyer reasonable access to any information retained by Sellers (excluding any Sales Information) to the extent reasonably necessary to allow Buyer to perform a financial statement audit for the years ended December 31, 2007, 2008 and 2009, and Sellers will provide reasonable cooperation and support to Buyer in connection with that audit (other than during periods when Sellers are preparing annual or quarterly public filings); provided that, Buyer will pay to Sellers any and all incremental costs incurred by Sellers to provide such reasonable access, cooperation and support. Buyer will preserve all records so delivered by Sellers for a period of six years following the Closing and will allow each Seller reasonable access to such records at all reasonable times for a purpose reasonably related to (i) such Seller’s ownership of an Interest in the Companies or (ii) the performance by it of its obligations, and the enforcement by it of its rights, hereunder. If Buyer desires to dispose of any such records prior to the expiration of the six-year period referenced above, Buyer will provide notice of same to Sellers, and Sellers will have a period of 10 days to deliver written notice to Buyer that Sellers elect to have such records delivered to them (at the expense of Sellers). If Sellers fail to deliver such notice within the 10-day period referenced above, Buyer may dispose of the subject records.

     Section 8.11 Rights to Name. Immediately prior to the Closing, the Companies will transfer and assign, without warranty of title and for no consideration whatsoever, all right, title and interest to the name “Crosstex” and the Crosstex Marks to Crosstex Energy.

     Section 8.12 Removal of Crosstex Marks. As soon as practicable, but in any event within 120 days after the Closing, Buyer must remove or cover, from the Midstream Assets any and all names, marks and logos constituting the Crosstex Marks.

     Section 8.13 Amendment to the Companies’ Certificates. Immediately after the Closing, Buyer agrees to file an amendment to each Company’s certificate of limited partnership, assumed name certificate and other Governing Documents, in a form reasonably acceptable to Sellers that provides for a change in the name of the Company, which name does not contain the word “Crosstex” (but uses Southcross or something other than “Crosstex”).

     Section 8.14 Excluded Assets. After the date hereof and at least one (1) Business Day prior to Closing, the appropriate Company will convey, transfer and assign the assets and properties described in Section 8.14 of the Disclosure Schedule (the “Excluded Assets”) to a Seller, an Affiliate or Affiliates of Sellers or a third party. Such conveyance, transfer and assignment will be (i) for no consideration whatsoever, save and except for the assumption by the assignee of all liabilities attributable or relating directly or indirectly to the Excluded Assets, whether arising before, on or after the date of assignment, and (ii) on an “as is, where is” basis without any representations and warranties by each Company, including any warranty of title, fitness for purpose, or merchantability. Buyer acknowledges that the Excluded Assets are not included in the Midstream Assets or the Assigned Assets or the property, assets or liabilities of any Company to be indirectly acquired by Buyer as a result of the transactions contemplated hereby or otherwise.

     Section 8.15 Assigned Assets. Section 8.15 of the Disclosure Schedule describes certain assets (the “Assigned Assets”) that are currently used in the operation of the Midstream Assets, but that are owned by Affiliates of the Companies. Immediately prior to, and contingent upon, Closing, Sellers will cause the Assigned Assets to be transferred to one or more of the Companies. Such conveyance, transfer and assignment will be (i) for no consideration whatsoever, save and except for the assumption by the assignee of all liabilities attributable or relating directly or indirectly to the Assigned Assets, whether arising before, on or after the date of assignment, and (ii) on an “as is, where is” basis without any representations and warranties by any Affiliate of the Companies, including any warranty of title, fitness for purpose, or merchantability. Upon that transfer, the Assigned Assets will be Midstream Assets and will, from and after the assignment, be subject to Sellers’ representations and warranties set forth in Article IV of this Agreement. At Sellers’ option, the Companies may cause some or all of the Assigned Assets to be transferred (without any warranties) to a newly-formed entity. Upon a transfer of Assigned Assets to a newly-formed entity, that entity will be a “Company,” and all equity interests of that entity will be “Interests,” and that Company and the related Interests will be subject, in all respects, to this Agreement. The Assigned Assets will not include any Hedges.

     Section 8.16 HSR Filing. Prior to the execution of this Agreement, Sellers and Buyer have filed with the Federal Trade Commission and the Department of Justice, as applicable, the notification and report forms required under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”). Buyer and Seller will, as promptly as practicable, furnish any supplemental information which may be requested in connection therewith. Buyer and Sellers will use Reasonable Efforts to: (a) make or modify all other filings and submissions on a prompt and timely basis in connection with the filings required under the HSR Act, and (b) resolve any objection asserted by any Governmental Entity to the transactions contemplated by

this Agreement. Sellers and Buyer will each bear all of their own costs and expenses relating to the compliance with this Section.

     Section 8.17 Affiliate Arrangements. Except for obligations specified in this Agreement, with respect to the agreements and arrangements listed in Section 8.17 of the Disclosure Schedule, which will continue after the Closing in accordance with their terms as in effect on the date of this Agreement, all agreements and arrangements between and among the Companies, on the one hand, and Sellers and their Affiliates (other than the Companies), on the other hand, and all liabilities and obligations of the Companies, on the one hand, and Sellers and their Affiliates (other than the Companies), on the other hand, will automatically terminate in their entirety effective as of the Closing without any further actions by the parties and thereby be deemed voided, cancelled and discharged in their entirety. Without limiting the generality of the foregoing, except with respect to the agreements and arrangements listed in Section 8.17 of the Disclosure Schedule effective upon the Closing, all intercompany accounts among the Companies, on the one hand, and Sellers and their Affiliates (other than the Companies), on the other hand, that then remain outstanding will be terminated, voided, cancelled and discharged.

     Section 8.18 Seller Hedges. Prior to Closing, Sellers and Buyer will cooperate with respect to each of the Seller Hedges to attempt to achieve one of the following (in the descending order of priority as follows):

     (a) enter into a novation of the Seller Hedge with the financial counterparty at no cost to Buyer, Seller or their respective Affiliates, so that: (i) Buyer assumes, or causes an Affiliate or other Person to assume, the financial position under the Seller Hedge, and (ii) Seller and its Affiliates have no further liability with respect to that Seller Hedge;

     (b) enter into an arrangement with the counterparty to the Hydrocarbon sales or purchase agreement associated with the Seller Hedge so that the Seller Hedge can be eliminated, with any costs, fees and expenses required to eliminate the Seller Hedge that are payable by Seller or its Affiliates being an adjustment to the Purchase Price in accordance with Section 1.3(a)(i)(G); provided that, neither Sellers nor their Affiliates will enter into an arrangement that would result in an adjustment to the Purchase Price pursuant to Section 1.3(a)(i)(G) without Buyer’s prior approval;

     (c) subject to satisfaction of Sellers’ internal credit policies, a Seller or one of its Affiliates and Buyer may enter into enter into a financial Hedge that offsets the Seller Hedge under a mutually agreeable ISDA and that provides, in a manner reasonably acceptable to Sellers, credit capacity or margin requirements in the form and amount of Seller’s or its Affiliate’s underlying position; or

     (d) if not otherwise dealt with under subsections (a) through (c) of this Section 8.18, on or as soon as practicable after the Closing Date, a Seller or its Affiliate (other than a Company) will enter into a Hedge that offsets the Seller Hedge, and the Purchase Price will be adjusted in accordance with Section 1.3(a)(i)(F) or (ii)(D).

     Section 8.19 Release.

     (a) Effective on and as of the Closing, each Seller, for itself and its Affiliates and its and their respective successors and assigns, hereby unconditionally and irrevocably releases, waives and forever discharges Buyer and each Company and their respective Affiliates and their respective agents, employees, representatives, officers, directors, managers, past and present, and the heirs, successors and assigns of all of the foregoing (collectively, the “Seller Released Parties”), from any and all debts, liabilities, claims, demands, losses, actions and causes of action, suits, judgments and controversies of any kind whatsoever (whether known or unknown, contingent or fixed, accrued or unaccrued) in connection with or otherwise related to the Companies or their respective businesses (other than claims by Sellers for indemnification which such Seller is entitled to make pursuant to ARTICLE XI or for any liabilities or obligations of Buyer under this Agreement or for any agreements or arrangements that this Agreement expressly provides will continue after Closing or with respect to the Formosa Claim (for the avoidance of doubt, Sellers acknowledge that the Formosa Claim is an Excluded Liability and subject to Sellers’ indemnity obligations in Section 11.2)) (collectively, the “Seller Released Claims”) that such Seller has or claims to have now or arising in the future out of events or circumstances accruing on or before the Closing Date against any or all of Seller Released Parties. Each Seller further agrees not to file or bring any claim, suit, action, complaint or arbitration with respect to any Seller Released Claim and each Seller agrees to indemnify, defend and hold harmless the Seller Released Parties from any Seller Released Claims brought by Seller or its Affiliates (other than the Companies).

     (b) Effective on and as of the Closing, Buyer, for itself and its Affiliates (including the Companies) and its and their respective successor and assigns, hereby unconditionally and irrevocably releases, waives and forever discharges each Seller and their respective Affiliates and their respective agents, employees, representatives, officers, directors, managers, past and present, and the heirs, successors and assigns of all of the foregoing (collectively, the “Buyer Released Parties”), from any and all debts, liabilities, claims, demands, losses, actions and causes of action, suits, judgments and controversies of any kind whatsoever (whether known or unknown, contingent or fixed, accrued or unaccrued) in connection with or otherwise related to the Companies or their respective businesses (other than claims by Buyer for indemnification which Buyer is entitled to make pursuant to ARTICLE XI or for any liabilities or obligations of Sellers under this Agreement or for any agreements or arrangements that this Agreement expressly provides will continue after Closing) (collectively, the “Buyer Released Claims”) that Buyer has or claims to have now or arising in the future out of events or circumstances accruing on or before the Closing Date against any or all of Buyer Released Parties. Buyer further agrees not to file or bring any claim, suit, action, complaint or arbitration with respect to any Buyer Released Claim and Buyer agrees to indemnify, defend and hold harmless the Buyer Released Parties from any Buyer Released Claims brought by any of the Seller Released Parties.

     Section 8.20 Certain Consents by Sellers. Each Seller, individually, and Crosstex GP as the general partner of each Company, hereby consents to the sale of the Interests by each other Seller on the terms and conditions set forth in this Agreement for all purposes, including but not limited to, pursuant to each Company’s Governing Documents, as amended through the date hereof.

     Section 8.21 Certain Accounts Payable. Sellers covenant and agree to pay all negative Seller Imbalances and accounts payable of each Company to the extent validly incurred and attributable to the period prior to the Effective Time (other than (i) accounts payable of the Companies for capital expenditures relating to the projects listed in Section 1.3(a)(i)(D) of the Disclosure Schedule, (ii) for any negative Company Imbalances, as the parties agree that such accounts payable and imbalances are subject to adjustment pursuant to Section 1.3, and (iii) for any negative Third Person Imbalances which are being retained by the Companies), including any accounts payable that were not included in the Final Settlement Statement as a result of a good faith dispute as provided in Section 1.3(a)(ii)(C), but which amounts are subsequently determined to be payable and any settlement payments due with respect to liquids product inventory that are subject to the adjustment set forth in Section 1.3(a)(i)(E).

     Section 8.22 Certain Accounts Receivable. The Excluded Assets include all positive Seller Imbalances and accounts receivable of the Companies (or otherwise related to the Midstream Assets or Assigned Assets, but excluding any positive Company Imbalances (which are subject to adjustment pursuant to Section 1.3) and any positive Third Person Imbalances (which are retained by the Companies)) to the extent attributable to the period prior to the Effective Time and, with respect to the Excluded Assets, any accounts receivables, revenues or payments of any nature attributable to any periods (before, on or after the Closing Date). Buyer covenants and agrees, and will cause the Companies, to: (i) cooperate with Sellers, at Sellers’ expense and as reasonably requested by Sellers, in the collection of these accounts receivable, and (ii) immediately pay to Sellers any payments received by Buyer or the Companies on or after the Closing Date with respect to those accounts receivable. Sellers covenant and agree, and will cause their Affiliates, to immediately pay to Buyer or any Company designated by Buyer, any payments received by Seller or any of its Affiliates with respect to accounts receivable of any Company (or otherwise related to the Midstream Assets or any Assigned Assets) to the extent attributable to any period on or after the Effective Time and for any reimbursements from customers received by Sellers for capital projects, the costs of which are paid or incurred by the Companies after the Effective Time.

     Section 8.23 Surety Bonds and Letters of Credit. Buyer agrees to use its Reasonable Efforts to provide, on or before the Closing Date and effective as to business or operations of the Companies, the Midstream Assets and the Assigned Assets from and after the Effective Time, security acceptable to the counterparty or beneficiaries of the surety bonds and letters of credit that are listed in Section 4.13(d) of the Disclosure Schedule, with respect to the Companies, the Midstream Assets and the Assigned Assets that were issued by, or on behalf of, either Seller or any of their Affiliates.

     Section 8.24 Non-Competition; Confidentiality.

     (a) Until the first anniversary of the Closing Date, no Seller will, and each Seller will cause each of its Affiliates (collectively, the “Restricted Persons”) not to, directly or indirectly, own, manage, operate, control or participate in the ownership, management, operation or control of any business, whether in corporate, proprietorship or partnership form or otherwise, engaged in gas gathering, gas transportation or gas processing (but excluding gas treating or dew point control) (a “Restricted Business”) within a radius of ten miles from any gas processing plant or pipeline that is a part of the Midstream Assets or the Assigned Assets on the Closing Date (the “Restricted Area”); provided, however, that no such Restricted Person will be deemed to be so

competing by reason of: (i) the acquisition, directly or indirectly (including by purchase, exchange, joint venture, merger or otherwise) of a Restricted Business so long as the amount of the consideration in that acquisition that is allocated to assets within the Restricted Area is no more than 10% of the aggregate consideration in the overall transaction, (ii) any acquisition of Seller or any of its Affiliates by, or any merger, reorganization or consolidation by Seller or any of its Affiliates with, any Person that is not an Affiliate of any Seller on the Closing Date and which, directly or indirectly, engages in a Restricted Business in the Restricted Area, or (iii) owning securities in companies listed on the New York Stock Exchange, the American Stock Exchange, or quoted on the National Association of Securities Dealers Automatic Quotation System (NASDAQ) or any other securities exchange in the United States or any other country, provided that the direct and beneficial ownership of any class of securities in any of such entities by any such Restricted Person is not more than 10% of the aggregate number of outstanding shares, units or interests of such class of securities.

     (b) Until the first anniversary of the Closing Date, each Seller will not, and each Seller will cause each other Restricted Person and their respective officers, directors, consultants, employees and advisors not to, directly or indirectly, (i) disclose, reveal, divulge or communicate to any Person, any Confidential Information (as defined below) other than: (x) to authorized officers, directors, consultants, employees and advisors of Seller and Affiliates that have a reasonable need to know and that agree to maintain the confidentiality of Confidential Information in accordance with this Agreement and (y) as reasonably required, to exercise any rights or obligations or in connection with any dispute under this Agreement or (ii) use or otherwise exploit any Confidential Information for its own benefit or for the benefit of anyone other than Buyer. The Restricted Persons will not have any obligation to keep confidential any Confidential Information if and to the extent disclosure thereof is specifically required by Law; provided, however, that in the event disclosure is required by applicable Law, Sellers shall, to the extent reasonably possible, provide Buyer with prompt notice of such requirement prior to making any disclosure so that Buyer may seek an appropriate protective order. For purposes of this Section 8.24(b), “Confidential Information” shall mean any confidential information that applies solely to any Company and the Midstream Assets or any Assigned Assets, including, to the extent applicable, customers, customer lists, products, prices, fees, costs, trade secrets, plans, suppliers, competitors, markets or other specialized information or proprietary matters. “Confidential Information” does not include, and there shall be no obligation hereunder with respect to, information that (i) is generally available to the public on the Closing Date or (ii) becomes generally available to the public or a Seller or a Restricted Party other than as a result of a disclosure not otherwise permissible under this Agreement.

     (c) The covenants and undertakings contained in this Section 8.24 relate to matters which are of a special, unique and extraordinary character and a violation of any of the terms of this Section 8.24 will cause irreparable injury to the parties, the amount of which will be impossible to estimate or determine and which cannot be adequately compensated. Therefore, without the necessity of proving actual damages, Buyer will be entitled to an injunction, restraining order or other equitable relief from any court of competent jurisdiction in the event of any breach of this Section 8.24. The rights and remedies provided by this Section 8.24 are cumulative and in addition to any other rights and remedies which Buyer may have hereunder or at law or in equity. If Buyer were to seek damages for any breach of this Section 8.24, the portion

of the Adjusted Purchase Price which is allocated by the Parties to the foregoing covenant, if any, shall not be considered a measure of or limit on such damages.

     (d) The Parties agree that, if any court of competent jurisdiction in a final nonappealable judgment determines that a specified time period, a specified geographical area, a specified business limitation or any other relevant feature of this Section 8.24 is unreasonable, arbitrary or against public policy, then a lesser time period, geographical area, business limitation or other relevant feature which is determined to be reasonable, not arbitrary and not against public policy may be enforced against the applicable Party.

     Section 8.25 Sellers’ Letters of Credit.

     (a) At Closing, to secure Sellers’ indemnity obligations (if any) under Article XI, Sellers will deliver to Buyer Sellers’ Letters of Credit substantially in the forms attached to this Agreement as Exhibits D-1 and D-2. Each of these Sellers’ Letters of Credit will be in an amount equal to 5% of the Adjusted Purchase Price. One of these will be for a term of six months from the Closing Date (together with any one or more letters of credit issued in substitution thereof pursuant to Section 8.25(b), the “6-Month LC”) and the other will be for a term of twelve months from the Closing Date (together with any one or more letters of credit issued in substitution thereof pursuant to Section 8.25(c), the “12-Month LC”). If, at Closing, there is a Disputed Amount, Sellers will deliver to Buyer Sellers’ Letter of Credit substantially in the form attached to this Agreement as Exhibit D-3 for a term of six months from the Closing Date in an amount equal to the Disputed Amount (together with any one or more letters of credit issued in substitution thereof pursuant to Section 8.25(c), the “Disputed Amount LC”).

     (b) If, prior to the expiry of any 6-Month LC: (i) Buyer has made one or more claims for indemnification in accordance with Article XI, (ii) a claim is unresolved, and (iii) the amount of unresolved claims exceeds the amount of the 12-Month LC, then, upon Buyer’s written request at least three Business Days prior to the expiry of such 6-Month LC, Sellers will deliver to Buyer a substitute 6-Month LC for a term ending six months after the expiry of such 6-Month LC in an amount equal to which the amount of unresolved claims (made in accordance with Article XI) exceeds the amount of the 12-Month LC. If Sellers fail to deliver that substitute 6-Month LC at least one Business Day prior to the expiry of any 6-Month LC, Buyer may draw on such 6-Month LC for payment directly into the Escrow Account described in Section 8.25(e) an amount equal to which the amount of unresolved claims (made in accordance with Article XI) exceeds the amount of the 12-Month LC.

     (c) If, prior to the expiry of any 12-Month LC: (i) Buyer has made one or more claims for indemnification in accordance with Article XI, (ii) a claim is unresolved, and (iii) the amount of unresolved claims exceeds the amount of any outstanding 6-Month LC, then, upon Buyer’s written request at least three Business Days prior to the expiry of such 12-Month LC, Sellers will deliver to Buyer a substitute 12-Month LC thereof for term ending six months after the expiry of such 12-Month LC in an amount equal to which the amount of unresolved claims (made in accordance with Article XI) exceeds the amount of any outstanding 6-Month LC. If Sellers fail to deliver that substitute 12-Month LC at least one Business Day prior to the expiry of any 12-Month LC, Buyer may draw on such 12-Month LC for payment directly into the Escrow Account described in Section 8.25(e) an amount equal to which the amount of unresolved claims (made in accordance with Article XI) exceeds the amount of any outstanding 6-Month LC.

     (d) If the dispute relating to the Final Settlement Statement is not fully resolved prior to the expiry of any Disputed Amount LC, then, upon Buyer’s written request at least three Business Days prior to the expiry of such Disputed Amount LC, Sellers will deliver to Buyer a substitute Disputed Amount LC for term ending six months after the expiry of such Disputed Amount LC in the amount that is still the subject of dispute up to the full Disputed Amount. If Sellers fail to deliver that substitute Disputed Amount LC at least one Business Day prior to the expiry of any Disputed Amount LC, Buyer may draw the amount that is still the subject of dispute up to the entire amount of such Disputed Amount LC for payment directly into the Escrow Account described in Section 8.25(e).

     (e) After Closing, Buyer will open a deposit account (the “Escrow Account”) with Bank of America. The Escrow Account will: (i) only contain amounts paid into escrow pursuant to Section 8.25(b), (c) and (d) (together with any interest or proceeds earned thereon while in escrow; and funds paid into the account pursuant to Section 8.25(b) and (c) will be segregated in separate sub-accounts from funds paid into the account pursuant to Section 8.25(d)), (ii) the funds paid into the account pursuant to Section 8.25(b) and (c) will be used solely to satisfy indemnity claims of Buyer made in accordance with Article XI and (iii) the funds paid into the account pursuant to Section 8.25(d) will be used solely to satisfy claims with respect to the Disputed Amount. Funds held in the Escrow Account will only be released by: (i) joint check signed by a Seller and Buyer, (ii) as to the funds paid into the account pursuant to Section 8.25(b) and (c), upon the final, non-appeallable order of a Governmental Entity, or (iii) as to the funds paid into the account pursuant to Section 8.25(d), upon the determination by the Referral Firm in accordance with Section 1.3(c). Sellers and Buyer will execute and deliver written instructions to implement the terms of this section, including disbursement instructions when any claim has been resolved. All funds in the Escrow Account remaining after resolution of Buyer claims secured by the escrow will be paid promptly to Sellers. Sellers will pay one-half, and Buyers will pay one-half, of all fees and charges relating to the Escrow Account.

     Section 8.26 Acquisition Proposal. From and after the date of this Agreement until the earlier of the Closing or the termination of this Agreement, none of Sellers or the Companies, or any of their Affiliates, and none of their respective officers, directors, employees, representatives, advisors or consultants, will, directly or indirectly, (i) solicit, initiate, or knowingly encourage any Acquisition Proposal (defined below) or (ii) engage in discussions or negotiations with, or disclose any nonpublic information relating to the Companies to, any Person that is considering making or has made an Acquisition Proposal. If any of Sellers, the Companies or their respective Affiliates receive any Acquisition Proposal after the date of this Agreement, Sellers will immediately communicate to Buyer that it has received an Acquisition Proposal. The term “Acquisition Proposal,” as used herein, means any offer or proposal for, or any indication of interest in, a merger, sale, consolidation or other business combination involving any Company or any of its assets or the acquisition of any equity interest in any Company or any Assigned Assets other than (a) the transactions contemplated by this Agreement and (b) any transactions involving the acquisition of Sellers and/or an Affiliate of Sellers other than a Company.

Effective immediately prior to Closing, Sellers shall assign to one or more of the Companies, all rights under any transferable confidentiality and/or non-disclosure agreements entered into in connection with any attempt by Sellers to market or sell the Midstream Assets, the Assigned Assets or the Companies. From and after Closing, upon Buyer’s written request and at Buyer’s sole cost, Sellers will reasonably cooperate

with Buyer to enforce any non-transferable agreements with other Persons with respect to the confidentiality and non-disclosure of confidential information of the Companies.

Transactions are entered into under those agreements with respect to the Midstream Assets and the Assigned Assets and also with respect to Excluded Assets. Buyer and Sellers will each use Reasonable Efforts to enter into a novation of any transactions under those NAESB agreements with respect to any transactions or obligations to be performed after the Effective Time that relate to the Midstream Assets and the Assigned Assets. If a novation of any of those agreements are not finalized by Closing, Buyer and a Seller or one of its Affiliates will enter into a “back-to-back” arrangement on substantially the same terms for such transaction and that will provide, in a manner reasonably acceptable to Sellers, credit capacity and margin requirements in the form and amount of Seller’s or its Affiliate’s underlying position.

If, prior to Closing, a consent with respect to any contract contained in Item 2 or 7 of Section 3.5 of the Disclosure Schedule is not obtained, then Sellers and/or appropriate Affiliate thereof and Buyer will enter into an Alternative Arrangement with respect thereto under substantially the same terms for such contracts.

Such notice will set forth with reasonable specificity to the extent reasonably known at that time (i) the basis under this Agreement, and the facts that otherwise form the basis of such claim, (ii) the estimate

of the amount of such claim (which estimate will not be conclusive of the final amount of such claim) and an explanation of the calculation of such estimate, including a statement of any significant assumptions employed therein, and (iii) the date on and manner in which the party delivering such notice became aware of the existence of such claim.

If any claim or demand for which a party (an “Indemnifying Party”) would be liable to another party to this Agreement under Section 11.2 or Section 11.3 (“Indemnified Party”) is asserted against or sought to be collected from an Indemnified Party by a third party, the Indemnified Party will with reasonable promptness notify the Indemnifying Party of such claim or demand, but the failure so to notify the Indemnifying Party will not relieve the Indemnifying Party of its obligations under this Article XI, except to the extent the Indemnifying Party demonstrates that the defense of such claim or demand is

materially prejudiced thereby. The Indemnifying Party will have 30 days from receipt of the above notice from the Indemnified Party (in this Section 11.4, the “Notice Period”) to notify the Indemnified Party whether or not the Indemnifying Party desires, at the Indemnifying Party’s sole cost and expense, to defend the Indemnified Party against such claim or demand; provided, that the Indemnified Party is hereby authorized prior to and during the Notice Period to file any motion, answer or other pleading that it deems necessary or appropriate to protect its interests or those of the Indemnifying Party and not prejudicial to the Indemnifying Party. If the Indemnifying Party elects to assume the defense of any such claim or demand, the Indemnified Party will have the right to employ separate counsel at its own expense and to participate in the defense thereof. If the Indemnifying Party elects not to assume the defense of such claim or demand (or fails to give notice to the Indemnified Party during the Notice Period), the Indemnified Party will be entitled to assume the defense of such claim or demand with counsel of its own choice, at the expense of the Indemnifying Party. If the claim or demand is asserted against both the Indemnifying Party and the Indemnified Party and based on the advice of counsel reasonably satisfactory to the Indemnified Party there are one or more defenses available to the Indemnified Party that are not available to the Indemnifying Party or there is a conflict of interest which renders it inappropriate for the same counsel to represent both the Indemnifying Party and the Indemnified Party, the Indemnifying Party will be responsible for paying separate counsel for the Indemnified Party; provided, however, that the Indemnifying Party will not be responsible for paying for more than one separate firm of attorneys to represent all of the Indemnified Parties, regardless of the number of Indemnified Parties. If the Indemnifying Party elects to assume the defense of such claim or demand, (i) no compromise or settlement thereof may be effected by the Indemnifying Party without the Indemnified Party’s written consent (which will not be unreasonably withheld) unless the sole relief provided is monetary damages that are paid in full by the Indemnifying Party and (ii) the Indemnified Party will have no liability with respect to any compromise or settlement thereof effected without its written consent (which will not be unreasonably withheld).

     Section 11.5 Exclusivity. Each Seller, each Company and Buyer agree that after Closing, except as otherwise provided in Section 8.6(d), Section 8.24 and Section 12.11 of this Agreement, the sole and exclusive relief and remedy available to any party to this Agreement in relation to any breach, default, or nonperformance of any representation, warranty, covenant, or agreement made or entered into by a party to this Agreement or under any certificate, instrument, or document delivered pursuant to this Agreement: (a) will be Damages, and (b) any claim for those Damages can only be brought under, and in accordance with, the terms and provisions of this Article XI, provided, that there shall be no such limitations on remedies with respect to claims involving fraud, intentional misrepresentation or willful misconduct.

     Section 11.6 Limited to Actual Damages. The indemnification obligations of the parties provided in this Article XI will be limited to actual Damages (including lost profits with respect to a breach of Section 4.13 (Contracts)) and will not include incidental, consequential, indirect, punitive, special or exemplary Damages, provided that any incidental, consequential, indirect, punitive, special or exemplary Damages recovered by a third Person (including a Governmental Entity, but excluding any Affiliate of any party) against a party entitled to indemnity pursuant to this Article XI will be included in the Damages recoverable from the indemnitor under such indemnity.

     Section 11.7 Limitation of Liability.

     (a) This Section 11.7(a) does not apply to a breach of the Specified Representations and Warranties or to claims under Section 11.2(ii) or (iii). Except for Damages arising from a breach of the Specified Representations and Warranties, Sellers are not liable, and will not be required to indemnify or hold harmless the Buyer Indemnitees, on account of any Damages under Section 11.2(i) unless the Damages arising from that breach (or related breaches that arise out of substantially the same event or circumstance) exceeds $50,000. In addition, until the liability of Sellers in respect of aggregated Damages under Section 11.2(i) exceeds the amount that is equal to $4,000,000, Seller will have no liability under Section 11.2(i). If Damages under Section 11.2(i) (other than the Specified Representations and Warranties for which Sellers will be, subject to the conditions set forth in Section 11.7(b), liable to the full extent of all Damages under Section 11.2(i)) exceed $4,000,000, then, subject to the limitations in Section 11.7(b), Sellers will be liable to the full extent of all Damages under Section 11.2(i) in excess of $4,000,000, (other than the Specified Representations and Warranties for which Sellers will be, subject to the conditions set forth in Section 11.7(b), liable to the full extent of all Damages under Section 11.2(i)).

     (b) This Section 11.7(b) does not apply to claims for indemnification pursuant to Section 11.2(iii). Subject to all of the terms and conditions of this Article XI, Sellers are not liable to the Buyer Indemnitees, and the Buyer Indemnitees are not entitled to indemnification from Sellers and the Buyer Indemnitees waive and release Sellers and their Affiliates from any such liability for: (a) all indemnifiable Damages under Section 11.2(i) (except for Damages arising from a breach of any of the Specified Representations and Warranties), in excess of 10% of the total Post-Closing Adjusted Purchase Price, and (b) Damages arising from a breach of any of the Specified Representations and Warranties or arising under Sections 11.2(ii) in excess of the total Post-Closing Adjusted Purchase Price (the maximum limit in (a) or (b) as applicable being the “Crosstex Cap Limitation”). Sellers are not liable for any Damages under Sections 11.2(i) or (ii) in excess of the Crosstex Cap Limitation.

     Section 11.8 Indemnification Despite Negligence. It is the express intention of Sellers, the Companies and Buyer that each party to be indemnified pursuant to this Article XI will be indemnified and held harmless as provided for under this Article XI, notwithstanding that any Damages that are otherwise subject to the indemnity arise out of or result from the ordinary, strict, sole, or contributory negligence of such party and regardless of whether any other party (including the other parties to this Agreement) is or is not also negligent. Sellers, the Companies and Buyer acknowledge that the foregoing complies with the express negligence rule and is conspicuous.

     Section 11.9 Tax Treatment of Indemnity Payments. All indemnity payments made under this Agreement, including any payment made under Section 8.7 will be treated as Purchase Price adjustments for Tax purposes.

This Agreement (including the Disclosure Schedule and Exhibits) and other writings referred to in, or delivered pursuant, to this Agreement, constitute the entire agreement between Buyer, Sellers and the Companies with respect to the subject matter of this Agreement and supersede all prior agreements and understandings, both written and oral, between Sellers, the Companies and Buyer with respect to the subject matter of this Agreement. Sellers, the Companies and Buyer each acknowledge that no other party to this Agreement, nor any agent or attorney of any other party to this Agreement, has made any promise, representation or warranty whatsoever not contained herein, and that none of Buyer, Sellers or the Companies have executed or authorized the execution of this Agreement in reliance upon any such promise, representation or warranty not contained in this Agreement.

     Section 12.3 Amendment. This Agreement may not be amended or modified except by an instrument in writing signed by all the parties to this Agreement.

     Section 12.4 Binding Effect; Assignment; No Third Party Benefit. This Agreement will be binding upon and inure to the benefit of Sellers, the Companies and Buyer and their respective legal representatives, successors, and permitted assigns. Except as otherwise expressly provided in this Agreement, neither this Agreement nor any of the rights, interests, or obligations hereunder may be assigned by any of the parties to this Agreement without the prior written consent of the other parties, which consent may be withheld in such party’s sole judgment; provided, however, without the consent of Sellers or any Company (but effective only upon written notice to Sellers and the Companies accompanied by a fully executed copy of the assignment), Buyer may, without relieving it of its obligations hereunder, (a) assign this Agreement and its rights and obligations to any one or more Affiliates of Buyer that agree in writing to assume all obligations and liabilities of Buyer under this Agreement and/or (b) collaterally assign this Agreement to any Person providing financing to Buyer. Except as provided in Section 8.6 and Article XI, nothing in this Agreement, express or implied, is intended to or will confer upon any Person other than the parties to this Agreement, and their respective heirs, legal representatives, successors, and permitted assigns, any rights, benefits, or remedies of any nature whatsoever under or by reason of this Agreement.

     Section 12.5 Severability. If any provision of this Agreement is held to be unenforceable, this Agreement will be considered divisible and such provision will be deemed inoperative to the extent it is deemed unenforceable, and in all other respects this Agreement will remain in full force and effect; provided, however, that if any such provision may be made

enforceable by limitation thereof, then such provision will be deemed to be so limited and will be enforceable to the maximum extent permitted by Applicable Law.

     Section 12.6 GOVERNING LAW. THIS AGREEMENT WILL BE GOVERNED BY AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF TEXAS, WITHOUT REGARD TO THE PRINCIPLES OF CONFLICTS OF LAWS THEREOF.

     Section 12.7 Further Assurances. From time to time following the Closing, at the request of any party to this Agreement and without further consideration, the other party or parties to this Agreement will execute and deliver to the requesting party such instruments and documents and take other actions (but without incurring any material financial obligation) as the requesting party reasonably requests in order to consummate more fully and effectively the transactions contemplated by this Agreement.

     Section 12.8 Counterparts. This Agreement may be executed in any number of identical counterparts, each of which for all purposes will be deemed an original, and all of which will constitute collectively, one agreement. It is not necessary that each party to this Agreement execute the same counterpart so long as identical counterparts are executed by each party. This Agreement may be validly executed and delivered by facsimile or other electronic transmission.

     Section 12.9 Schedules. Nothing in the Disclosure Schedule is intended to broaden the scope of any representation or warranty contained in the Agreement or to create any covenant unless clearly specified to the contrary herein. Any disclosure in one section of the Disclosure Schedule will be deemed to be disclosed in all other sections of the Disclosure Schedule where it is reasonably apparent that such disclosure applies. Inclusion of any item in the Disclosure Schedule (a) does not represent a determination that such item is material nor will it be deemed to establish a standard of materiality, (b) does not represent a determination that such item did not arise in the Ordinary Course of Business, (c) does not represent a determination that the transactions contemplated by the Agreement require the consent of third parties and (d) will not constitute, or be deemed to be, an admission of any kind to any third party concerning such item. The Disclosure Schedule includes descriptions of instruments or brief summaries of certain aspects of the Companies and their business and operations. The descriptions and brief summaries are not necessarily complete and are provided in the Disclosure Schedule to identify documents or other materials previously delivered or made available and are qualified by reference to the documents or other materials themselves.

     Section 12.10 Time of Essence. With regard to all dates and time periods set forth or referred to in this Agreement, time is of the essence.

     Section 12.11 Specific Performance. The parties to this Agreement recognize that in the event one or more of Sellers or Companies should refuse to perform under the provisions of this Agreement, monetary damages alone will not be adequate. Buyer shall therefore be entitled, in addition to any other remedies which may be available, including money damages, and without the necessity of proving actual damages have resulted or would result in the absence thereof, to obtain specific performance of the terms of this Agreement. In the event of any action to enforce this Agreement specifically, each of Sellers and the Companies hereby waives the defense that there is an adequate remedy at law. In no event will any of Sellers or the Companies be entitled

to seek specific performance with respect to any obligations of Buyer arising under this Agreement.
