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

Section 3.18 Material Agreements. Crosstex has provided the Purchasers with, or made available to the Purchasers through the Crosstex SEC Documents, correct and complete copies of all material agreements (as defined in Section 601(b)(10) of Regulation S-K promulgated by the Commission) and of all exhibits to the Crosstex SEC Documents, including amendments to or other modifications of pre-existing material agreements, entered into by Crosstex.

Section 3.19 Subsequent Offerings. Until the Lock-Up Date, Crosstex does not presently intend to 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.

The execution, delivery and performance of this Agreement and the Registration Rights Agreement by such Purchaser and the consummation by such Purchaser of the transactions contemplated hereby and thereby will not (a) conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, any material agreement to which such Purchaser is a party or by which the Purchaser is bound or to which any of the property or assets of such Purchaser is subject, (b) conflict with or result in any violation of the provisions of the organizational documents of such Purchaser, or (c) violate any statute, order, rule or regulation of any court or governmental agency or body having jurisdiction over such Purchaser or the property or assets of such Purchaser, except in the case of clauses (a) and (c), for such conflicts, breaches, violations or defaults as would not prevent the consummation of the transactions contemplated by this Agreement and the Registration Rights Agreement.

Section 4.06 Unregistered Securities. Such Purchaser represents that:

(a) Investment. The Purchased Units are being acquired for its own account or the account of clients for whom it exercises investment discretion, not as a nominee, and with no intention of distributing the Purchased Units or any part thereof, and that Purchaser has no present intention of selling or granting any participation in or otherwise distributing the same in any transaction in violation of the securities laws of the United States or any state, without prejudice, however, to such Purchaser’s right at all times to (subject to such Purchaser’s agreement contained in Section 4.07 hereof) sell or otherwise dispose of all or any part of the Purchased Units under a registration statement under the Securities Act and applicable state securities laws or under an exemption from such registration available thereunder (including, without limitation, if available, Rule 144 promulgated thereunder). If such Purchaser should in the future decide to dispose of any of the Purchased Units, such Purchaser understands and

agrees (a) that it may do so only in compliance with the Securities Act and applicable state securities law, as then in effect, which may include a sale contemplated by any registration statement pursuant to which such securities are being offered, and (b) that stop-transfer instructions to that effect will be in effect with respect to such securities subject to withdrawal thereof as described in Section 6.07(b).

(b) Nature of Purchasers. Such Purchaser represents and warrants to, and covenants and agrees with, Crosstex that, (a) it is an “accredited investor” within the meaning of Rule 501 of Regulation D promulgated by the Commission pursuant to the Securities Act and (b) by reason of its business and financial experience it has such knowledge, sophistication and experience in making similar investments and in business and financial matters generally so as to be capable of evaluating the merits and risks of the prospective investment in the Purchased Units, is able to bear the economic risk of such investment and, at the present time, would be able to afford a complete loss of such investment.

(c) Receipt of Information; Authorization. Such Purchaser acknowledges that it has (a) had access to Crosstex’s periodic filings with the Commission, including Crosstex’s Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, and Current Reports filed on Form 8-K and (b) been provided a reasonable opportunity to ask questions of and receive answers from Representatives of Crosstex regarding such matters sufficient to enable such Purchaser to evaluate the risks and merits of purchasing the Purchased Units and consummating the transactions contemplated by the Basic Documents.

(d) Legend. It is understood that the certificates evidencing the Purchased Units will bear the following legend: “These securities have not been registered under the Securities Act of 1933, as amended. They may not be sold or offered for sale in the absence of a registration statement in effect with respect to the securities under such Act or an opinion of counsel satisfactory to the Company that such registration is not required or unless sold pursuant to Rule 144 of such Act.” The securities may be pledged in connection with a bona fide margin account or other loan secured by such securities.

Section 4.07 Lock-Up. Such Purchaser agrees that from and after Closing it will not sell any of the Purchased Units or the Common Units into which such Purchased Units convert prior to the Lock-up Date.

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.

(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

with all laws or rules and regulations of the Commission, NASDAQ or other Governmental Authority.

Section 6.07 Removal of Legend.

(a) Each Purchaser may request Crosstex to remove the legend described in Section 4.06(d) from the certificates evidencing the Purchased Units by submitting to Crosstex such certificates, together with an opinion of counsel to the effect that such legend is no longer required under the Securities Act or applicable state laws, as the case may be. Crosstex shall cooperate with such Purchaser to effect the removal of such legend.

(b) Certificates evidencing Common Units acquired by any Purchaser upon conversion of the Purchased Units shall not contain any legend (including the legend set forth in Section 4.06(d)), (i) while a registration statement covering the resale of such security is effective under the Securities Act, or (ii) following any sale of such Common Units pursuant to Rule 144, or (iii) if such Common Units are eligible for sale under Rule 144(k), or (iv) if such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the Commission). Crosstex agrees that following the date that such registration statement is declared effective by the Commission, or at such time as such legend is no longer required under this Section 6.07(b), it will, as promptly as practicable following the delivery by a Purchaser to Crosstex or Crosstex’s transfer agent of a certificate representing Common Units issued with a restrictive legend, instruct Crosstex’s transfer agent to, or deliver or cause to be delivered to such Purchaser a certificate representing such Common Units that is free from all restrictive and other legends. While a registration statement covering the resale of such security is effective or at any time after removal of any such restrictive legend, Crosstex shall withdraw any and all stop-transfer instructions with respect to such security. Notwithstanding anything in this Agreement or any other Basic Document to the contrary, Crosstex may not make any notation on its records or give instructions to any transfer agent of Crosstex that enlarge the restrictions on transfer set forth in this Section.

This Agreement, the other Basic Documents and the other agreements and documents referred to herein are intended by the parties as a final expression of their agreement and intended to be a complete and exclusive statement of the agreement and understanding of the parties hereto in respect of the subject matter contained herein and therein.

Section 6.09 Governing Law. This Agreement will be construed in accordance with and governed by the laws of the State of Texas without regard to principles of conflicts of laws.

Section 6.10 Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of

Exhibit A – Form of Registration Rights Agreement

See Attached

See Exhibit 4.1 to this Current Report on Form 8-K.

Exhibit A

Exhibit B – Form of Opinion of Crosstex Counsel

Capitalized terms used but not defined herein have the meanings assigned to such terms in the Senior Subordinated Series D Unit Purchase Agreement (the “Purchase Agreement”). 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:

(i) Each of Crosstex and its “significant subsidiaries” that are organized under the laws of the States of Delaware or Texas (the “Crosstex Subsidiaries,” and, collectively with Crosstex, the “Crosstex Entities”) has been duly formed and is validly existing and in good standing under the laws of the jurisdiction of its formation with all necessary, partnership or limited liability company power and authority to own, lease, use or operate its respective properties and to carry on its business as its business is now conducted as described in Crosstex’s Annual Report on Form 10-K for the period ended December 31, 2006 (the “Annual Report”). Each of the Crosstex Entities is duly qualified or registered for the transaction of business and in good standing as a foreign limited partnership or limited liability company, as applicable, in each of the jurisdictions set forth in Exhibit A to such opinion.

(ii) As of the date hereof, and prior to the sale and issuance of the Purchased Units as contemplated by the Purchase Agreement, the issued and outstanding limited partner interests of Crosstex consist of 21,982,039 Common Units, 4,668,000 Subordinated Units, 12,829,650 Senior Subordinated Series C Units and the Incentive Distribution Rights, as defined in the Partnership Agreement. The only issued and outstanding general partner interests of Crosstex are the interests of the General Partners described in the Partnership Agreement. All outstanding Common Units, Subordinated Units, Senior Subordinated Series C Units and Incentive Distribution Rights and the limited partner interests represented thereby have been duly authorized and validly issued in accordance with the Partnership Agreement and are fully paid (to the extent required under the Partnership Agreement) and nonassessable (except as such nonassessability may be affected by matters described in Sections 17-303, 17-607 and 17-804 of the Delaware Revised Uniform Limited Partnership Act (“Delaware LP Act”)).

(iii) To our knowledge, except as described in the Annual Report and except for options granted pursuant to the Crosstex Energy GP, LLC Long-Term Incentive Plan, there are no outstanding or authorized (i) options, warrants, preemptive rights, subscriptions, calls, or other rights, convertible or exchangeable securities, agreements, claims or commitments of any character obligating any Crosstex Entity to issue, transfer or sell any partnership interests or other equity interest in, any Crosstex Entity or securities convertible into or exchangeable for such partnership interests, (ii) obligations of any Crosstex Entity to repurchase, redeem or otherwise acquire any partnership interests or equity interests of any Crosstex Entity or any such securities or agreements listed in clause (i) of this sentence or (iii) voting trusts or similar agreements to which any Crosstex Entity is a party with respect to the voting of the equity interests of any Crosstex Entity. To our knowledge, none of the offering or sale of the Purchased Units or the registration of the Common Units underlying the Purchased Units pursuant to the Registration Rights Agreement, all as contemplated by the Purchase Agreement, gives rise to any rights for or relating to the registration of any Common Units or other securities of Crosstex
