The Purchaser has sought such accounting, legal and tax advice as it has considered necessary to make an informed investment decision with respect to its acquisition of the Purchased Units.

(c) Residency. The Purchaser shall cooperate reasonably with Crosstex to provide any information necessary for any applicable securities filings.

(d) Legends. The Purchaser understands that, until such time as the Purchased Units have been registered pursuant to the provisions of the Securities Act, or the Purchased Units are eligible for resale pursuant to Rule 144 promulgated under the Securities Act without any restriction as to the number of securities as of a particular date that can then be immediately sold, the Purchased Units will bear a restrictive legend as provided in the Partnership Agreement. The Purchaser understands that, until such time as the Conversion Units have been registered pursuant to the provisions of the Securities Act, or the Conversion Units are eligible for resale pursuant to Rule 144 promulgated under the Securities Act without any restriction as to the number of securities as of a particular date that can then be immediately sold, the Conversion Units will bear a restrictive legend as provided in the Partnership Agreement.

(e) Purchase Representation. The Purchaser is purchasing the Purchased Units for its own account and not with a view to distribution in violation of any securities laws. The Purchaser has been advised and understands that neither the Purchased Units nor the Conversion Units have been registered under the Securities Act or under the “blue sky” laws of any jurisdiction and may be resold only if registered pursuant to the provisions of the Securities Act (or if eligible, pursuant to the provisions of Rule 144 promulgated under the Securities Act or

pursuant to another available exemption from the registration requirements of the Securities Act). The Purchaser has been advised and understands that Crosstex, in issuing the Purchased Units, is relying upon, among other things, the representations and warranties of the Purchaser contained in this Article IV in concluding that such issuance is a “private offering” and is exempt from the registration provisions of the Securities Act.

(f) Rule 144. The Purchaser understands that there is no public trading market for the Purchased Units, that none is expected to develop and that the Purchased Units must be held indefinitely unless and until Purchased Units or Conversion Units received upon conversion thereof are registered under the Securities Act or an exemption from registration is available. The Purchaser has been advised of and is aware of the provisions of Rule 144 promulgated under the Securities Act.

(g) Reliance by Crosstex. The Purchaser understands that the Purchased Units are being offered and sold in reliance on a transactional exemption from the registration requirements of federal and state securities laws and that Crosstex is relying upon the truth and accuracy of the representations, warranties, agreements, acknowledgments and understandings of the Purchaser set forth herein in order to determine the applicability of such exemptions and the suitability of the Purchaser to acquire the Purchased Units and the Conversion Units issuable upon conversion thereof.

ARTICLE V
INDEMNIFICATION, COSTS AND EXPENSES

Section 5.01 Indemnification by Crosstex. Crosstex agrees to indemnify the 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 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), whether or not involving a third party claim, as a result of, arising out of, or in any way related to (i) the failure of any of the representations or warranties made by Crosstex contained herein to be true and correct in all material respects as of the date hereof (except with respect to any provisions including the word “material” or words of similar import, with respect to which such representations and warranties must have been true and correct) or (ii) the breach of any covenants of Crosstex contained herein, provided that, in the case of the immediately preceding clause (i), such claim for indemnification is made prior to the expiration of such representation or warranty; provided, however, that for purposes of determining when an indemnification claim has been made, the date upon which a Purchaser Related Party shall have given notice (stating in reasonable detail the basis of the claim for indemnification) to Crosstex shall constitute the date upon which such claim has been made.

Section 5.02 Indemnification by the Purchaser. The Purchaser agrees 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 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), whether or not involving a third party claim, as a result of, arising out of, or in any way related to (i) the failure of any of the representations or warranties made by the Purchaser contained herein to be true and correct in all material respects as of the date hereof or (ii) the breach of any of the covenants of the Purchaser contained herein, provided that, in the case of the immediately preceding clause (i), 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 for purposes of determining when an indemnification claim has been made, the date upon which a Crosstex Related Party shall have given notice (stating in reasonable detail the basis of the claim for indemnification) to the Purchaser shall constitute the date upon which such claim has been made; provided, further, that the liability of the Purchaser shall not be greater in amount than the Purchase Price.

Section 5.03 Indemnification Procedure.

(a) A claim for indemnification for any matter not involving a third party claim may be asserted by notice to the party from whom indemnification is sought; provided, however, that failure to so notify the indemnifying party shall not preclude the indemnified party from any indemnification which it may claim in accordance with this Article V, except as otherwise provided in Sections 5.01 and 5.02.

(b) 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 (each, a “Third Party Claim”), the Indemnified Party shall give the indemnitor hereunder (the “Indemnifying Party”) written notice of such Third Party Claim 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 Third Party 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 such Third Party Claim, it shall promptly, and in no event later than five (5) days, 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/or 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, within ten (10) Business Days of when the Indemnified Party provides written notice of a Third Party Claim, failed (y) to assume the defense or settlement of such Third Party Claim and employ counsel and (z) notify the Indemnified Party of such assumption, 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 settlement or 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.

Section 5.04 Tax Matters. All indemnification payments under this Article V shall be adjustments to the Purchase Price except as otherwise required by applicable Law.

ARTICLE VI

(c) By Crosstex if (i) there shall have been a breach of any representation or warranty on the part of the Purchaser set forth in this Agreement or in any other Basic Document, or if any such representation or warranty of the Purchaser shall have become untrue, in either case such that the conditions set forth in Section 2.04(c) would be incapable of being satisfied by the Outside Date; or (ii) there shall have been a breach in any material respect by the Purchaser of any of their respective covenants or agreements hereunder, and with respect to such clause (i) or

ARTICLE VII
MISCELLANEOUS

Section 7.01 Expenses.

(b) Notwithstanding the foregoing, if Crosstex raises equity capital from another source (other than pursuant to its LTIP) prior to February 28, 2010 and the Closing has not occurred at such time, Crosstex shall pay the reasonable fees and expenses incurred by the Purchaser and its Affiliates in connection with the due diligence, preparation, negotiation and execution of this Agreement as well as the other Basic Documents, including, without limitation, legal, accounting, advisory and other reasonable fees and expenses regardless of whether the transactions contemplated by this Agreement are consummated; provided, that, the expenses of the Purchaser and its Affiliates paid out of such proceeds shall not exceed $400,000 in the aggregate.

Section 7.02 Interpretation. Article, Section, Schedule and Exhibit references in this Agreement are references to the corresponding Article, Section, Schedule or Exhibit to this Agreement, unless otherwise specified. All Exhibits and Schedules to this Agreement are hereby incorporated and made a part hereof as if set forth in full herein and are an integral part of this

Agreement. All references to instruments, documents, Contracts and agreements are references to such instruments, documents, Contracts and agreements as the same may be amended, supplemented and otherwise modified from time to time, unless otherwise specified. The word “including” shall mean “including but not limited to” and shall not be construed to limit any general statement that it follows to the specific or similar items or matters immediately following it. 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. Any reference in this Agreement to $ shall mean U.S. dollars. Whenever any determination, consent or approval is to be made or given by the Purchaser, such action shall be in the 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, (i) 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 and (ii) the parties hereto shall negotiate in good faith to modify the Basic Documents so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible. When calculating the period of time before which, within which or following which any act is to be done or step taken pursuant to the Basic Documents, the date that is the reference date in calculating such period shall be excluded. If the last day of such period is a non-Business Day, the period in question shall end on the next succeeding Business Day. Any words imparting the singular number only shall include the plural and vice versa. The words such as “herein,” “hereinafter,” “hereof” and “hereunder” refer to this Agreement as a whole and not merely to a subdivision in which such words appear unless the context otherwise requires. The provision of a Table of Contents, the division of this Agreement into Articles, Sections and other subdivisions and the insertion of headings are for convenience of reference only and shall not affect or be utilized in construing or interpreting this Agreement.

Section 7.03 Survival of Provisions. The representations and warranties set forth in Sections 3.01(a), 3.02, 3.07, 3.08, 3.10, 3.11, 4.01, 4.02, 4.04 and 4.05 hereunder shall survive the execution and delivery of this Agreement indefinitely, the representations and warranties set forth in Section 3.16 shall survive for a period of three (3) years following the Closing Date regardless of any investigation made by or on behalf of Crosstex or the Purchaser, and the other representations and warranties set forth herein shall survive for a period of eighteen (18) months following the Closing Date regardless of any investigation made by or on behalf of Crosstex or the Purchaser. The covenants made in this Agreement or any other Basic Document shall survive the Closing and remain operative and in full force and effect regardless of acceptance of any of the Purchased Units and payment therefor and repayment, conversion or repurchase thereof. Regardless of any purported general termination of this Agreement, the provisions of Article V and all indemnification rights and obligations of Crosstex and the Purchaser thereunder, Section 6.02 and this Article VII shall remain operative and in full force and effect as between Crosstex and the Purchaser, unless Crosstex and the Purchaser execute a writing that expressly (with specific references to the applicable Section or subsection of this Agreement) terminates such rights and obligations as between Crosstex and the Purchaser.

Section 7.04 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. Any investigation by or on behalf of any party shall not be deemed to constitute a waiver by the party taking such action of compliance with any representation, warranty, covenant or agreement contained herein.

Section 7.05 Binding Effect; Assignment.

(a) Binding Effect. This Agreement shall be binding upon Crosstex, the 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 Purchased Units. All or any portion of Purchased Units purchased pursuant to this Agreement may be sold, assigned or pledged by the Purchaser, subject to compliance with applicable securities laws, Section 4.05 hereof and the Registration Rights Agreement, and, except as provided in the Basic Documents, any such assignment shall not affect the rights of the Purchaser hereunder.

(c) Assignment of Rights. The Purchaser’s rights and obligations hereunder (including the right to seek indemnification) may be transferred or assigned in whole or in part by the Purchaser to any Affiliate of the Purchaser without the consent of Crosstex or the other parties hereto. Upon any such permitted transfer or assignment, references in this Agreement to the Purchaser (as they apply to the transferor or assignor, as the case may be) shall thereafter apply to such transferee or assignee of the Purchaser unless the context otherwise requires. Without the written consent of Crosstex, which consent shall not be unreasonably withheld, no portion of the rights and obligations of the Purchaser under this Agreement may be assigned or transferred by the Purchaser or such a transferee of Purchased Units to a Person that is not an Affiliate of the Purchaser. No portion of the rights and obligations of Crosstex under this Agreement may be transferred or assigned without the prior written consent of the Purchaser, which consent shall not be unreasonably withheld.

Section 7.06 Non-Disclosure.

(a) The Purchaser agrees to abide by the obligations of the Non-Disclosure Agreement as if it were a party thereto and the parties agree that such agreement shall survive until the second anniversary of the Closing Date, at which time the Non-Disclosure Agreement shall terminate and be of no further force or effect.

(b) Other than the Form 8-Ks to be filed in connection with this Agreement, the Crosstex Entities and any of their respective Representatives shall disclose the identity of, or any other information concerning, the Purchaser or any of its Affiliates only after providing the Purchaser a reasonable opportunity to review and comment on such disclosure (with such comments being incorporated or reflected, to the extent reasonable, in any such disclosure); provided, however, that nothing in this Section 7.06 shall delay any required filing or other disclosure with the Commission, NASDAQ or any Governmental Authority or otherwise hinder the Crosstex Entities’ or their Representatives’ ability to timely comply with all laws or rules and regulations of the Commission, NASDAQ or other Governmental Authority.
