The execution, delivery and performance by Crosstex of the Basic Documents and compliance by Crosstex with the terms and provisions hereof and thereof, and the issuance and sale by Crosstex of the Purchased Units, do not and will not (a) assuming the accuracy of the representations and warranties of the Purchasers contained herein and their compliance with the covenants contained herein, violate any provision of any Law or Permit having applicability to Crosstex or any of its Subsidiaries or any of their respective Properties, (b) conflict with or result in a violation or breach of any provision of the certificate of limited partnership or other organizational documents of Crosstex, or the Partnership Agreement, or any organizational documents of any of Crosstex’s Subsidiaries, (c) require any consent, approval or notice under or result in a violation or breach of or constitute (with or without due notice or lapse of time or both) a default (or give rise to any right of termination, cancellation or acceleration) under any contract, agreement, instrument, obligation, note, bond, mortgage, license, loan or credit agreement to which Crosstex or any of its Subsidiaries is a party or by which Crosstex or any of its Subsidiaries or any of their respective Properties may be bound, or (d) result in or require the creation or imposition of any Lien upon or with respect to any of the Properties now owned or hereafter acquired by Crosstex

or any of its Subsidiaries, except where any such conflict, violation, default, breach, termination, cancellation, failure to receive consent, approval or notice, or acceleration with respect to the foregoing provisions of this Section 3.07 would not be, individually or in the aggregate, reasonably likely to result in a Crosstex Material Adverse Effect.

Section 3.08 Authority, Enforceability. Crosstex has all necessary partnership power and authority to execute, deliver and perform its obligations under the Basic Documents, and the execution, delivery and performance by Crosstex of the Basic Documents has been duly authorized by all necessary action on the part of the General Partner; and the Basic Documents constitute the legal, valid and binding obligations of Crosstex, enforceable in accordance with their terms, except as such enforceability may be limited by bankruptcy, insolvency, fraudulent transfer and similar laws affecting creditors’ rights generally or by general principles of equity and except as the rights to indemnification may be limited by applicable law. No approval from the holders of the Common Units and/or Senior Subordinated Series D Units is required in connection with Crosstex’s issuance and sale of the Purchased Units to the Purchasers.

Section 3.09 Approvals. Except for the approvals that have already been obtained, no authorization, consent, approval, waiver, license, qualification or written exemption from, nor any filing, declaration, qualification or registration with, any Governmental Authority or any other Person is required in connection with the execution, delivery or performance by Crosstex of any of the Basic Documents, except where the failure to receive such authorization, consent, approval, waiver, license, qualification or written exemption from, or to make such filing, declaration, qualification or registration would not, individually or in the aggregate, be reasonably likely to have a Crosstex Material Adverse Effect.

Section 3.10 MLP Status. Crosstex has, for each taxable year beginning after December 31, 2001, during which Crosstex was in existence, met the gross income requirements of Section 7704(c)(2) of the Internal Revenue Code of 1986, as amended.

Section 3.12 Certain Fees.

Section 3.14 Insurance. Crosstex and its Subsidiaries are insured by insurers of recognized financial responsibility against such losses and risks and in such amounts as are prudent and customary in the businesses in which they are engaged. Crosstex does not have any reason to believe that it or any Subsidiary will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business.

Section 3.15 Internal Accounting Controls. Crosstex and its Subsidiaries maintain a system of internal accounting controls sufficient to provide reasonable assurance that (i) transactions are executed in accordance with management’s general or specific authorizations, (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain asset accountability, (iii) access to assets is permitted only in accordance with management’s general or specific authorization, and (iv) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences. Crosstex is not aware of any failures of such internal accounting controls.

Section 3.16 Form S-3 Eligibility. Crosstex satisfies the requirements for use of Form S-3 under the Securities Act.

Section 3.17 Listing and Maintenance Requirements. The issuance and sale of the Purchased Units does not contravene NASDAQ rules and regulations.

Section 3.19 Subsequent Offerings. Until the Company Lock-Up Date, Crosstex will not grant, issue or sell any Partnership Securities, any securities convertible into or exchangeable therefor or take any other action that may result in the issuance of any of the foregoing.

Section 3.20 Confidential Information. To the knowledge of Crosstex, none of its employees or executive officers has disclosed material non-public information (other than the fact that Crosstex was contemplating a private financing) to any prospective investor who has not entered into a confidentiality or non-disclosure agreement between such prospective investor and Crosstex relating to such information.

Section 3.21 Further Agreements of Crosstex. Crosstex shall prepare the final prospectus supplement relating to the Purchased Units and the offering thereof in a form approved by the Purchasers and file such final prospectus supplement and the accompanying base prospectus, which together constitute the Prospectus, pursuant to Rule 424(b) under the Securities Act not later than the Commission’s close of business on the second business day following the execution and delivery of this Agreement.

ARTICLE V
INDEMNIFICATION, COSTS AND EXPENSES

Section 5.01 Indemnification by Crosstex. Crosstex agrees to indemnify each Purchaser and its Representatives (collectively, “Purchaser Related Parties”) from, and hold each of them harmless against, any and all losses, actions, suits, proceedings (including any investigations, litigation or inquiries), demands, and causes of action, and, in connection therewith, and promptly upon demand, pay or reimburse each of them for all reasonable costs, losses, liabilities, damages, or expenses of any kind or nature whatsoever, including, without limitation, the reasonable fees and disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them as a result of, arising out of, or in any way related to the breach of any of the representations, warranties or covenants of Crosstex contained herein, provided such claim for indemnification relating to a breach of any representation or warranty is made prior to the expiration of such representation or warranty.

Section 5.02 Indemnification by the Purchasers. Each Purchaser agrees, severally and not jointly, to indemnify Crosstex, the General Partners and their respective Representatives (collectively, “Crosstex Related Parties”) from, and hold each of them harmless against, any and all losses, actions, suits, proceedings (including any investigations, litigation or inquiries), demands, and causes of action, and, in connection therewith, and promptly upon demand, pay or reimburse each of them for all reasonable costs, losses, liabilities, damages, or expenses of any kind or nature whatsoever, including, without limitation, the reasonable fees and disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them as a result of, arising out of, or in any way related to the breach of any of the representations, warranties or covenants of such Purchaser contained herein, provided such claim for indemnification relating to a breach of any representation or warranty is made prior to the expiration of such representation or warranty, provided, however, that the liability of each Purchaser shall not be greater in amount than such Purchaser’s Allocated Purchase Price.

Section 5.03 Indemnification Procedure. Promptly after any Crosstex Related Party or Purchaser Related Party (hereinafter, the “Indemnified Party”) has received notice of any indemnifiable claim hereunder, or the commencement of any action, suit or proceeding by a third person, which the Indemnified Party believes in good faith is an indemnifiable claim under this Agreement, the Indemnified Party shall give the indemnitor hereunder (the “Indemnifying Party”) written notice of such claim or the commencement of such action, suit or proceeding, but failure to so notify the Indemnifying Party will not relieve the Indemnifying Party from any liability it may have to such Indemnified Party hereunder except to the extent that the Indemnifying Party is materially prejudiced by such failure. Such notice shall state the nature and the basis of such claim to the extent then known. The Indemnifying Party shall have the right to defend and settle, at its own expense and by its own counsel, any such matter as long as the Indemnifying Party pursues the same diligently and in good faith. If the Indemnifying Party undertakes to defend or settle, it shall promptly notify the Indemnified Party of its intention to do so, and the Indemnified Party shall cooperate with the Indemnifying Party and its counsel in all commercially reasonable respects in the defense thereof and the settlement thereof. Such cooperation shall include, but shall not be limited to, furnishing the Indemnifying Party with any

books, records and other information reasonably requested by the Indemnifying Party and in the Indemnified Party’s possession or control. Such cooperation of the Indemnified Party shall be at the cost of the Indemnifying Party. After the Indemnifying Party has notified the Indemnified Party of its intention to undertake to defend or settle any such asserted liability, and for so long as the Indemnifying Party diligently pursues such defense, the Indemnifying Party shall not be liable for any additional legal expenses incurred by the Indemnified Party in connection with any defense or settlement of such asserted liability; provided, however, that the Indemnified Party shall be entitled (i) at its expense, to participate in the defense of such asserted liability and the negotiations of the settlement thereof and (ii) if (A) the Indemnifying Party has failed to assume the defense and employ counsel or (B) if the defendants in any such action include both the Indemnified Party and the Indemnifying Party and counsel to the Indemnified Party shall have concluded that there may be reasonable defenses available to the Indemnified Party that are different from or in addition to those available to the Indemnifying Party or if the interests of the Indemnified Party reasonably may be deemed to conflict with the interests of the Indemnifying Party, then the Indemnified Party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the Indemnifying Party as incurred. Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not settle any indemnified claim without the consent of the Indemnified Party, unless the settlement thereof imposes no liability or obligation on, and includes a complete release from liability of, and does not contain any admission of wrong doing by, the Indemnified Party.

ARTICLE VI

The word “including” shall mean “including but not limited to.” Whenever Crosstex has an obligation under the Basic Documents, the expense of complying with that obligation shall be an expense of Crosstex unless otherwise specified. Whenever any determination, consent, or approval is to be made or given by the Purchasers, such action shall be in such Purchaser’s sole discretion unless otherwise specified in this Agreement. If any provision in the Basic Documents is held to be illegal, invalid, not binding, or unenforceable, such provision shall be fully severable and the Basic Documents shall be construed and enforced as if such illegal, invalid, not binding, or unenforceable provision had never comprised a part of the Basic Documents, and the remaining provisions shall remain in full force and effect.

Section 6.02 Survival of Provisions. The representations and warranties set forth in Sections 3.02, 3.08, 3.09, 3.11, 3.12 and 4.04 hereunder shall survive the execution and delivery of this Agreement indefinitely, and the other representations and warranties set forth herein shall survive for a period of twelve (12) months following the Closing Date regardless of any investigation made by or on behalf of Crosstex or the Purchasers. The covenants made in this Agreement or any other Basic Document shall survive the Closing of the transactions described

herein and remain operative and in full force and effect regardless of acceptance of any of the Purchased Units and payment therefor and repayment or repurchase thereof. All indemnification obligations of Crosstex and the Purchasers and the provisions of Article V shall remain operative and in full force and effect unless such obligations are expressly terminated in a writing referencing that individual Section, regardless of any purported general termination of this Agreement.

Section 6.03 No Waiver; Modifications in Writing.

(a) Delay. No failure or delay on the part of any party in exercising any right, power, or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, power, or remedy preclude any other or further exercise thereof or the exercise of any other right, power, or remedy. The remedies provided for herein are cumulative and are not exclusive of any remedies that may be available to a party at law or in equity or otherwise.

(b) Specific Waiver. Except as otherwise provided herein, no amendment, waiver, consent, modification, or termination of any provision of this Agreement or any other Basic Document (except in the case of the Partnership Agreement for amendments adopted pursuant to Section 13.1 thereof) shall be effective unless signed by each of the parties hereto or thereto affected by such amendment, waiver, consent, modification, or termination. Any amendment, supplement or modification of or to any provision of this Agreement or any other Basic Document, any waiver of any provision of this Agreement or any other Basic Document, and any consent to any departure by Crosstex from the terms of any provision of this Agreement or any other Basic Document shall be effective only in the specific instance and for the specific purpose for which made or given. Except where notice is specifically required by this Agreement, no notice to or demand on Crosstex in any case shall entitle Crosstex to any other or further notice or demand in similar or other circumstances.

Section 6.04 Binding Effect; Assignment.

(a) Binding Effect. This Agreement shall be binding upon Crosstex, each Purchaser, and their respective successors and permitted assigns. Except as expressly provided in this Agreement, 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 permitted assigns.

(b) Assignment of Rights. All or any portion of the rights and obligations of each Purchaser under this Agreement may be transferred by such Purchaser to any Affiliate of such Purchaser without the consent of Crosstex. No portion of the rights and obligations of each Purchaser under this Agreement may be transferred by such Purchaser to a non-Affiliate without the written consent of Crosstex.

Section 6.05 Non-Disclosure. Notwithstanding anything herein to the contrary, the Non-Disclosure Agreement shall remain in full force and effect regardless of any termination of this Agreement. Other than the Form 8-Ks to be filed in connection with this Agreement, Crosstex, the General Partner, their respective Subsidiaries and any of their respective Representatives shall disclose the identity of, or any other information concerning, any Purchaser

or any of its Affiliates only after providing such Purchaser a reasonable opportunity to review and comment on such disclosure; provided, however, that nothing in this Section 6.05 shall delay any required filing or other disclosure with the Commission, NASDAQ or any Governmental Authority or otherwise hinder Crosstex, the General Partner, their respective Subsidiaries or their Representatives’ ability to timely comply with all laws or rules and regulations of the Commission, NASDAQ or other Governmental Authority.

(“Crosstex”) and the purchasers named therein (the “Purchasers”). Crosstex shall furnish to the Purchasers at the Closing an opinion of Xxxxx Xxxxx L.L.P., counsel for Crosstex, addressed to the Purchasers and dated the Closing Date in form satisfactory to Xxxxxx & Xxxxxx L.L.P., counsel for the Purchasers, and the Purchasers, stating that:

(iii) No permit, consent, approval, authorization, order, registration, filing or qualification (“consent”) under the Delaware LP Act, the Delaware LLC Act, the federal law of the United States of America or the laws of the State of Texas is required in connection with the offering, issuance and sale by Crosstex of the Purchased Units, the execution, delivery and performance of the Purchase Agreement by Crosstex or the consummation by Crosstex of the transactions contemplated the Purchase Agreement, except for such consents (i) required under the Securities Act, the Exchange Act and state securities or “Blue Sky” laws, as to which we do not express any opinion, (ii) that have been obtained or made or (iii) that, if not obtained, would not, individually or in the aggregate, have a Material Adverse Effect.

(iv) The Registration Statement, at the Effective Time, and the Prospectus, as of its date, were, on their face, appropriately responsive, in all material respects, to the requirements of the Securities Act and the rules and regulations promulgated thereunder, except that in each case we express no opinion with respect to the financial statements and the notes and schedules thereto, and the financial and accounting data included or incorporated by reference in or omitted from the Registration Statement or the Prospectus.
