Each of Crosstex’s Subsidiaries has been duly incorporated or formed, as the case may be, and is validly existing and in good standing under the laws of the State or other jurisdiction of its incorporation or organization, as the case may be, and has all requisite power and authority, and has all governmental licenses, authorizations, consents and approvals necessary, to own, lease, use or operate its respective Properties and carry on its business as now being conducted, except where the failure to obtain such licenses, authorizations, consents and approvals would not be reasonably likely to have a Crosstex Material Adverse Effect. None of Crosstex nor any of its Subsidiaries are in default in the performance, observance or fulfillment of any provision of, in the case of Crosstex, the Partnership Agreement or its Certificate of Limited Partnership or, in the case of any Subsidiary of Crosstex, its respective certificate of incorporation, certification of formation, bylaws, limited liability company agreement or other similar organizational documents. Each of Crosstex and its Subsidiaries is duly qualified or licensed and in good standing as a foreign limited partnership, limited liability company or corporation, as applicable, and is authorized to do business in each jurisdiction in which the ownership or leasing of its respective Properties or the character of its respective operations makes such qualification

necessary, except where the failure to obtain such qualification, license, authorization or good standing would not be reasonably likely to have a Crosstex Material Adverse Effect.

Section 3.02 Capitalization and Valid Issuance of Purchased Units.

(a) As of the date of this Agreement, the issued and outstanding limited partner interests of Crosstex consist of 19,565,155 Common Units, 7,001,000 Subordinated Units and the Incentive Distribution Rights, as defined in the Partnership Agreement.

None of the offering or sale of the Senior Subordinated Series C Units or the registration of the Common Units underlying the Senior Subordinated Series C Units pursuant to the Registration Rights Agreement, all as contemplated by this Agreement, gives rise to any rights for or relating to the registration of any Common Units or other securities of the Partnership other than those rights granted to the General Partner or any of its Affiliates (as such term is defined in the Partnership Agreement) under Section 7.12 of the Partnership Agreement.

(c) (i) All of the issued and outstanding equity interests of each of Crosstex’s Subsidiaries (except Crosstex DC Gathering Company, J.V.) are owned, directly or indirectly, by Crosstex free and clear of any Liens (except for such restrictions as may exist under applicable Law and except for such Liens as may be imposed under the Crosstex Credit Facility or the Crosstex Master Shelf Agreement), and all such ownership interests have been duly authorized, validly issued and are fully paid (to the extent required in the organizational documents of Crosstex’s Subsidiaries, as applicable) and non-assessable (except as such nonassessability may be affected by matters described in Section 17-607 of the Delaware LP Act, Section 18-607 of

KPMG LLP is an independent public accounting firm with respect to Crosstex and the General Partner and has not resigned or been dismissed as independent public accountants of Crosstex or the General Partner as a result of or in connection with any disagreement with Crosstex on a matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure.

Section 3.04 No Material Adverse Change. Except as set forth in or contemplated by the Crosstex SEC Documents filed with the Commission on or prior to the date hereof, since December 31, 2005, Crosstex and its Subsidiaries have conducted their respective businesses in the ordinary course, consistent with past practice, and there has been no (a) change, event, occurrence, effect, fact, circumstance or condition that has had or would be reasonably likely to have a Crosstex Material Adverse Effect, (b) acquisition or disposition of any material asset by Crosstex or any of its Subsidiaries or any contract or arrangement therefor, otherwise than for fair value in the ordinary course of business or as disclosed in the Crosstex SEC Documents, or (c) material change in Crosstex’s accounting principles, practices or methods.

Section 3.05 Litigation. Except as set forth in the Crosstex SEC Documents, there is no action, suit, or proceeding pending (including any investigation, litigation or inquiry) or, to Crosstex’s knowledge, contemplated or threatened against or affecting any of the Crosstex Parties or any of their respective officers, directors, properties or assets, which (a) questions the validity of this Agreement or the Registration Rights Agreement or the right of Crosstex to enter into this Agreement or the Registration Rights Agreement or to consummate the transactions contemplated hereby and thereby or (b) (individually or in the aggregate) would be reasonably likely to result in a Crosstex Material Adverse Effect.

Section 3.06 No Conflicts; Compliance with Laws. The execution, delivery and performance by Crosstex of the Basic Documents and the execution, delivery and performance by Crosstex Energy Services, L.P. of the Chief Acquisition Agreement and compliance by Crosstex and Crosstex Energy Services, L.P. with the terms and provisions hereof and thereof, as applicable, 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 or approval, or acceleration with respect to the foregoing provisions of this Section 3.06 would not be, individually or in the aggregate, reasonably likely to result in a Crosstex Material Adverse Effect. Neither Crosstex nor any of its Subsidiaries is in violation of any judgment, decree or order or any law, statute, ordinance, rule or regulation applicable to Crosstex or its Subsidiaries, except as would not, individually or in the aggregate, have a Material Adverse Effect. Crosstex and its Subsidiaries possess all certificates, authorizations and permits issued by the appropriate regulatory authorities necessary to conduct their respective businesses, except where the failure to possess such certificates, authorizations or permits would not have, individually or in the aggregate, a Crosstex Material Adverse Effect, and neither Crosstex nor any such Subsidiary has received any notice of proceedings relating to the revocation or modification of any such certificate, authorization or permit, except where such potential revocation or modification would not have, individually in the aggregate, a Crosstex Material Adverse Effect. Neither Crosstex, nor any of its Subsidiaries, nor any director, officer, agent, employee or other person acting on behalf of Crosstex or any of its Subsidiaries has, in the course of its actions for, or on behalf of, Crosstex or any of its Subsidiaries (i) used any corporate funds for any unlawful contribution, gift, entertainment or other unlawful expenses relating to political activity; (ii) made any direct or indirect unlawful payment to any foreign or domestic government official or employee from corporate funds; (iii) violated or is in violation of any provision of the U.S. Foreign Corrupt Practices Act of 1977, as amended; or (iv) made any unlawful bribe, rebate, payoff, influence payment, kickback or other unlawful payment to any foreign or domestic government official or employee.

Crosstex has all necessary partnership power and authority to execute, deliver and perform its obligations under the Basic Documents and the Chief Acquisition Agreement and the execution, delivery and performance by Crosstex of the Basic Documents and the Chief Acquisition Agreement has been duly authorized by all necessary action on the part of the General Partner; and the Basic Documents and the Chief Acquisition Agreement 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 and/or the Subordinated Units is required in connection with Crosstex’s issuance and sale of the Purchased Units to the Purchasers or the conversion of the Purchased Units.

Section 3.08 Approvals. Except for the approvals required by the Commission in connection with any registration statement filed under the Registration Rights Agreement, approvals required by the Hart-Scott-Rodino Antitrust Improvements Act of 1976 and for approvals which 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 and the Chief

Acquisition Agreement, 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 3.09 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 3.10 Investment Company Status. Crosstex is not an “investment company” or a company controlled by an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

Section 3.11 Certain Fees. No fees or commissions are or will be payable by Crosstex to brokers, finders, or investment bankers with respect to the sale of any of the Purchased Units or the consummation of the transaction contemplated by this Agreement. Crosstex agrees that it will indemnify and hold harmless each Purchaser from and against any and all claims, demands, or liabilities for broker’s, finder’s, placement, or other similar fees or commissions incurred by Crosstex or alleged to have been incurred by Crosstex in connection with the sale of the Purchased Units or the consummation of the transactions contemplated by this Agreement.

Section 3.12 No Side Agreements. There are no agreements by, among or between Crosstex or any of its Affiliates, on the one hand, and any Purchaser or any of its Affiliates, on the other hand, with respect to the transactions contemplated hereby other than the Basic Documents, the XTXI Purchase Agreement and the XTXI Registration Rights Agreement nor promises or inducements for future transactions between or among any of such parties.

Section 3.13 Preemptive Rights or Registration Rights. Except as set forth in the agreement of limited partnership, limited liability company agreement or other organizational documents of the Crosstex Parties, there are no preemptive rights or other rights to subscribe for or to purchase, nor any restriction upon the voting or transfer of, any capital stock or partnership or membership interests of any of the Crosstex Parties, in each case pursuant to or any other agreement or instrument to which any of such entities is a party or by which any one of them may be bound. Neither the execution of this Agreement nor the issuance of the Purchase Units as contemplated by this Agreement or the conversion of the Purchased Units into Common Units gives rise to any rights for or relating to the registration of any Partnership Securities, other than as have been waived.

Section 3.14 No Registration Assuming the accuracy of the representations and warranties of each Purchaser contained in the Purchase Agreement, the issuance and sale of the Purchased Units pursuant to this Agreement is exempt from registration requirements of the Securities Act of 1933, as amended.

Section 3.15 No Integration. Neither Crosstex nor any of its Subsidiaries have, directly or indirectly through any agent, sold, offered for sale, solicited offers to buy or otherwise negotiated in respect of, any “security” (as defined in the Securities Act of 1933, as amended)

that is or will be integrated with the sale of the Purchased Units in a manner that would require registration under the Securities Act of 1933, as amended.

Section 3.16 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 nor 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 3.17 Internal Accounting Controls. Crosstex and the 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 3.18 Form S-3 Eligibility. Crosstex is eligible to register the resale of its Common Units and the Senior Subordinated Series C Units for resale by the Purchasers under Form S-3 promulgated under the Securities Act.

Section 3.19 Listing and Maintenance Requirements. Crosstex has not received notice (written or oral) from NASDAQ to the effect that it is not in compliance with the listing or maintenance requirements thereof. Crosstex is in compliance with all such 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 3.20 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.

This Agreement and the Registration Rights Agreement have been duly executed and delivered by such Purchaser and constitute legal, valid and binding obligations of such Purchaser; provided that, the enforceability thereof may be limited by bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws relating to or affecting creditors’ rights generally and by general principles of equity and except as the rights to indemnification may be limited applicable law (regardless of whether such enforceability is considered in a proceeding in equity or at law).

Section 4.03 No Breach. 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 or 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 and could not, individually or in the aggregate, reasonably be expected to have a material adverse effect on the financial condition or prospects of such Purchaser.

Section 4.04 Certain Fees. No fees or commissions are or will be payable by such Purchaser to brokers, finders, or investment bankers with respect to the purchase of any of the Purchased Units or the consummation of the transaction contemplated by this 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 or agent,

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 Securities and Exchange 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, (b) had access to information regarding the Chief Asset Acquisition and its potential effect on Crosstex’s operations and financial results and (c) 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.” These securities may be pledged in connection with a bona fide margin account or other loan secured by such securities.

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 a 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 the representations and warranties is made prior to the expiration of such representations and warranties, 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.

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.

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.

Section 6.08 Entire Agreement. 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. There are no restrictions, promises, warranties or undertakings, other than those set forth or referred to herein or the other Basic Documents with respect to the rights granted by Crosstex or any of its Affiliates or the Purchasers or any of their Affiliates set forth

herein or therein. This Agreement, the other Basic Documents and the other agreements and documents referred to herein or therein supersede all prior agreements and understandings between the parties with respect to such subject matter.

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 which counterparts, when so executed and delivered, shall be deemed to be an original and all of which counterparts, taken together, shall constitute but one and the same Agreement.

Section 6.11 Termination.

(a) In the event that any of the conditions to a party’s obligation to close specified in Section 2.05 is not satisfied at or prior to the Closing Date, such party may terminate this Agreement.

(b) In the event that the Closing Date does not take place on or before August 31, 2006, either party may terminate this Agreement.

(c) In the event of any termination of this Agreement pursuant to this Section 6.11, this Agreement shall forthwith become null and void. In the event of such termination, there shall be no liability on the part of any party hereto; provided that nothing herein shall relieve any party from any liability or obligation with respect to any willful breach of this Agreement.

ARTICLE II
REGISTRATION RIGHTS

Section 2.1 Shelf Registration.

(a) Shelf Registration. As soon as practicable following the Closing of the acquisition of the Purchased Units pursuant to the terms of the Purchase Agreement, but in any event within 30 days of the Closing, Crosstex shall prepare and file a Shelf Registration Statement covering the Registrable Securities. Crosstex shall use its commercially reasonable efforts to cause the Shelf Registration Statement to become effective no later than 120 days after the date of the Closing. A Shelf Registration Statement filed pursuant to this Section 2.1(a) shall be on such appropriate registration form of the Commission as shall be selected by Crosstex; provided, however, that if a prospectus supplement will be used in connection with the marketing of an Underwritten Offering from the Shelf Registration Statement and the Managing Underwriter at any time shall notify Crosstex in writing that, in the sole judgment of such Managing Underwriter, inclusion of detailed information to be used in such prospectus supplement is of material importance to the success of the Underwritten Offering of such Registrable Securities, Crosstex shall include such information in the prospectus unless it has determined, upon advice of counsel, that such information would violate the rules and regulations of the Commission or would cause such prospectus supplement to contain an untrue statement of a material fact or to omit to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading. Crosstex will use its commercially reasonable efforts to cause the Shelf Registration Statement filed pursuant to this Section 2.1(a) to be continuously effective under the Securities Act until the earlier of (i) all Registrable Securities covered by the Shelf Registration Statement have been distributed in the manner set forth and as contemplated in the Shelf Registration Statement, (ii) there are no longer any Registrable Securities outstanding or (iii) three years from the Closing (the “Effectiveness Period”). The Shelf Registration Statement when declared effective (including the documents incorporated therein by reference) will comply as to form in all material respects with all applicable requirements of the Securities Act and the Exchange Act and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. If the Shelf Registration Statement is not declared effective within 180 days after Closing, then the Purchasers (other than any Purchaser who has requested to not be included in the Shelf Registration Statement) shall be entitled to a payment (with respect to each of such Purchaser’s Purchased Units), as liquidated damages and not as a penalty, of 0.25% of the Purchase Price per 30-day period for the first sixty (60) days following the 120th day after Closing, with such payment amount increasing by an additional 0.25% of the Purchase Price per 30-day period for each subsequent 60 days, up to a maximum of 1.00% of the Purchase Price per 30-day period (the “Liquidated Damages”), until such time as the Shelf Registration Statement is declared effective or there are no longer any Registrable Securities outstanding. The Liquidated Damages shall accrue on a daily basis and be paid to each Purchaser in cash within ten (10) Business Days of the end of such 30-day period. The Purchasers’ rights (and any transferee’s rights pursuant to Section 2.10) under this Section 2.1 shall terminate when such Registrable Securities become eligible for resale under Rule 144(k) (or any similar provision then in force under the Securities Act). Notwithstanding anything to the contrary contained herein, Crosstex Energy, Inc. shall not be entitled to receive

any Liquidated Damages that arise out of any delay in effectiveness caused directly or indirectly by Crosstex Energy, Inc.

(b) Delay Rights. Notwithstanding anything to the contrary contained herein, Crosstex may, upon written notice to any Selling Holder whose Registrable Securities are included in the Shelf Registration Statement, suspend such Selling Holder’s use of any prospectus which is a part of the Shelf Registration Statement (in which event the Selling Holder shall discontinue sales of the Registrable Securities pursuant to the Shelf Registration Statement) if (i) Crosstex is pursuing an acquisition, merger, reorganization, disposition or other similar transaction and Crosstex determines in good faith that Crosstex’s ability to pursue or consummate such a transaction would be materially and adversely affected by any required disclosure of such transaction in the Shelf Registration Statement or (ii) Crosstex has experienced some other material non-public event the disclosure of which at such time, in the good faith judgment of Crosstex, would materially and adversely affect Crosstex; however, in no event shall any delay pursuant hereto exceed sixty (60) days in any one hundred-eighty (180) day period or ninety (90) days in any twelve-month period. Upon disclosure of such information or the termination of the condition described above, Crosstex shall provide prompt notice to the Selling Holders whose Registrable Securities are included in the Shelf Registration Statement, and shall promptly terminate any suspension of sales it has put into effect and shall take such other actions to permit registered sales of Registrable Securities as contemplated in this Agreement.

Section 2.2 Piggyback Registration.

(a) Participation. Commencing on the conversion of the Purchased Units to Common Units, if Crosstex at any time proposes to file a prospectus supplement to an effective Shelf Registration Statement with respect to an Underwritten Offering of Common Units for its own account or to register any Common Units for its own account for sale to the public in an Underwritten Offering or otherwise file any registration statement with the Commission relating to any Underwritten Offering of Common Units other than (x) a registration statement on Form S-8 (or any successor form) relating solely to employee benefit plans or (y) a registration statement on Form S-4 (or any successor form) relating solely to a Rule 145 transaction, then, as soon as practicable following the engagement of counsel to Crosstex to prepare the documents to be used in connection with an Underwritten Offering, Crosstex shall give notice of such proposed Underwritten Offering to the Holders, and such notice shall offer the Holders the opportunity to include in such Underwritten Offering such number of Registrable Securities (the “Included Registrable Securities”) as each such Holder may request in writing (a “Piggyback Registration”); provided, however, that Crosstex shall not be required to offer such opportunity to Holders if (i) the Holders do not offer a minimum of $5,000,000 of Registrable Securities and Other Registrable Securities, in the aggregate, (determined by multiplying the number of Registrable Securities and Other Registrable Securities owned by the average of the closing price on NASDAQ for Common Units for the ten (10) trading days preceding the date of such notice). The notice required to be provided in this Section 2.2(a) to Holders shall be provided on a Business Day pursuant to Section 3.1 hereof and receipt of such notice shall be confirmed by Holder. Holder shall then have two (2) Business Days to request inclusion of Registrable Securities in the Underwritten Offering. If no request for inclusion from a Holder is received within the specified time, such Holder shall have no further right to participate in such Piggyback

Registration. If, at any time after giving written notice of its intention to undertake an Underwritten Offering and prior to the closing of such Underwritten Offering, Crosstex shall determine for any reason not to undertake or to delay such Underwritten Offering, Crosstex may, at its election, give written notice of such determination to the Selling Holders and, (x) in the case of a determination not to undertake such Underwritten Offering, shall be relieved of its obligation to sell any Included Registrable Securities in connection with such terminated Underwritten Offering, and (y) in the case of a determination to delay such Underwritten Offering, shall be permitted to delay offering any Included Registrable Securities for the same period as the delay in the Underwritten Offering. Any Selling Holder shall have the right to withdraw such Selling Holder’s request for inclusion of such Selling Holder’s Registrable Securities in such offering by giving written notice to Crosstex of such withdrawal up to and including the time of pricing of such offering. No Holders shall be entitled to participate in any such Underwritten Offering under this Section 2.2(a) unless such Holder (together with any Affiliates that are Selling Holders) participating therein holds at least fifteen million ($15,000,000) of Registrable Securities and Other Registrable Securities, in the aggregate, (determined by multiplying the number of Registrable Securities and Other Registrable Securities owned by the average of the closing price for Common Units for the ten (10) trading days preceding the date of such notice).

(b) Priority of Piggyback Registration. If the Managing Underwriter or Underwriters of any proposed Underwritten Offering of Common Units included in a Piggyback Registration advises Crosstex that the total amount of Common Units which the Selling Holders and any other Persons intend to include in such offering exceeds the number which can be sold in such offering without being likely to have an adverse effect on the price, timing or distribution of the Common Units offered or the market for the Common Units, then the Common Units to be included in such Underwritten Offering shall include the number of Registrable Securities that such Managing Underwriter or Underwriters advises Crosstex can be sold without having such adverse effect, with such number to be allocated pro rata among the Selling Holders and any other Persons who have been or are granted registration rights on or after the date of this Agreement (“Other Holders”) who have requested participation in the Piggyback Registration (based, for each such Selling Holder or Other Holder, on the percentage derived by dividing (A) the number of Registrable Securities proposed to be sold by such Selling Holder or such Other Holder in such offering; by (B) the aggregate number of Common Units proposed to be sold by all Selling Holders and all Other Holders in the Piggyback Registration).

(c) Piggyback Registration by Crosstex Energy, Inc. To the extent any conflict exists between the rights granted to Crosstex Energy, Inc. pursuant to this Section 2.2 and rights granted to Crosstex Energy, Inc. pursuant to the Partnership Agreement (as defined in the Purchase Agreement) with respect to a Piggyback Registration, the provisions of this Agreement shall control.

Section 2.3 Underwritten Offering.

(a) S-3 Registration. In the event that a Selling Holder (together with any Affiliates that are Selling Holders) elects to dispose of Registrable Securities under the Shelf Registration Statement pursuant to an Underwritten Offering of at least fifteen million ($15,000,000) of Registrable Securities and Other Registrable Securities, Crosstex shall, at the

request of such Selling Holder, enter into an underwriting agreement in customary form with the Managing Underwriter or Underwriters, which shall include, among other provisions, indemnities to the effect and to the extent provided in Section 2.8, and shall take all such other reasonable actions as are requested by the Managing Underwriter in order to expedite or facilitate the disposition of the Registrable Securities; provided, however, that Crosstex management will not be required to participate in a roadshow or similar marketing effort.

(b) General Procedures. In connection with any Underwritten Offering (i) under Section 2.2 of this Agreement, Crosstex shall be entitled to select the Managing Underwriter or Underwriters, and (ii) under Section 2.3 of this Agreement, the Selling Holders shall be entitled to select the Managing Underwriter or Underwriters. In connection with an Underwritten Offering under Section 2.2 or Section 2.3 hereof, each Selling Holder and Crosstex shall enter into an underwriting agreement with the Managing Underwriter or Underwriters which contains such representations, covenants, indemnities and other rights and obligations as are customary in underwriting agreements for firm commitment offerings of equity securities. No Selling Holder may participate in such Underwritten Offering unless such Selling Holder agrees to sell its Registrable Securities on the basis provided in such underwriting agreement and completes and executes all questionnaires, powers of attorney, indemnities and other documents reasonably required under the terms of such underwriting agreement. Each Selling Holder may, at its option, require that any or all of the representations and warranties by, and the other agreements on the part of, Crosstex to and for the benefit of such underwriters also be made to and for such Selling Holder’s benefit and that any or all of the conditions precedent to the obligations of such underwriters under such underwriting agreement also be conditions precedent to its obligations. No Selling Holder shall be required to make any representations or warranties to or agreements with Crosstex or the underwriters other than representations, warranties or agreements regarding such Selling Holder and its ownership of the securities being registered on its behalf and its intended method of distribution and any other representation required by law. If any Selling Holder disapproves of the terms of an underwriting, such Selling Holder may elect to withdraw therefrom by notice to Crosstex and the Managing Underwriter; provided, however, that such withdrawal must be made prior to the pricing of such Underwritten Offering hereof to be effective. No such withdrawal or abandonment shall affect Crosstex’s obligation to pay Registration Expenses.

Section 2.4 Sale Procedures. In connection with its obligations contained in Sections 2.1, 2.2 and 2.3, Crosstex will, as expeditiously as possible:

(a) prepare and file with the Commission such amendments and supplements to the Shelf Registration Statement and the prospectus used in connection therewith as may be necessary to keep the Shelf Registration Statement effective for the Effectiveness Period and as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by the Shelf Registration Statement;

(b) furnish to each Selling Holder (i) as far in advance as reasonably practicable before filing the Shelf Registration Statement or any other registration statement contemplated by this Agreement or any supplement or amendment thereto, upon request, copies of reasonably complete drafts of all such documents proposed to be filed (including exhibits and each document incorporated by reference therein to the extent then required by the rules and

regulations of the Commission), and provide each such Selling Holder the opportunity to object to any information pertaining to such Selling Holder and its plan of distribution that is contained therein and make the corrections reasonably requested by such Selling Holder with respect to such information prior to filing the Shelf Registration Statement or such other registration statement and the prospectus included therein or any supplement or amendment thereto, and (ii) such number of copies of the Shelf Registration Statement or such other registration statement and the prospectus included therein and any supplements and amendments thereto as such Persons may reasonably request in order to facilitate the public sale or other disposition of the Registrable Securities covered by such Shelf Registration Statement or other registration statement;

(c) if applicable, use its commercially reasonable efforts to register or qualify the Registrable Securities covered by the Shelf Registration Statement or any other registration statement contemplated by this Agreement under the securities or blue sky laws of such jurisdictions as the Selling Holders or, in the case of an Underwritten Offering, the Managing Underwriter, shall reasonably request, provided that Crosstex will not be required to qualify generally to transact business in any jurisdiction where it is not then required to so qualify or to take any action which would subject it to general service of process in any such jurisdiction where it is not then so subject;

(d) promptly notify each Selling Holder and each underwriter, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of (i) the filing of the Shelf Registration Statement or any other registration statement contemplated by this Agreement or any prospectus included therein or any amendment or supplement thereto, and, with respect to such Shelf Registration Statement or any other registration statement or any post-effective amendment thereto, when the same has become effective; and (ii) any written comments from the Commission with respect to any filing referred to in clause (i) and any written request by the Commission for amendments or supplements to the Shelf Registration Statement or any other registration statement or any prospectus or prospectus supplement thereto;

(e) immediately notify each Selling Holder and each underwriter, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of (i) the happening of any event as a result of which the prospectus contained in the Shelf Registration Statement or any other registration statement contemplated by this Agreement or any supplemental amendment thereto, includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing; (ii) the issuance or threat of issuance by the Commission of any stop order suspending the effectiveness of the Shelf Registration Statement or any other registration statement contemplated by this Agreement, or the initiation of any proceedings for that purpose; or (iii) the receipt by Crosstex of any notification with respect to the suspension of the qualification of any Registrable Securities for sale under the applicable securities or blue sky laws of any jurisdiction. Following the provision of such notice, Crosstex agrees to as promptly as practicable amend or supplement the prospectus or prospectus supplement or take other appropriate action so that the prospectus or prospectus supplement does not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the

circumstances then existing and to take such other action as is necessary to remove a stop order, suspension, threat thereof or proceedings related thereto;

(f) upon request and subject to appropriate confidentiality obligations, furnish to each Selling Holder copies of any and all transmittal letters or other correspondence with the Commission or any other governmental agency or self-regulatory body or other body having jurisdiction (including any domestic or foreign securities exchange) relating to such offering of Registrable Securities;

(g) in the case of an Underwritten Offering, furnish upon request, (i) an opinion of counsel for Crosstex, dated the effective date of the applicable registration statement or the date of any amendment or supplement thereto, preliminary or prospectus supplement, and a letter of like kind dated the date of the closing under the underwriting agreement, and (ii) a “cold comfort” letter, dated the effective date of the applicable registration statement or the date of any amendment or supplement thereto, preliminary or prospectus supplement and a letter of like kind dated the date of the closing under the underwriting agreement, in each case, signed by the independent public accountants who have certified Crosstex’s financial statements included or incorporated by reference into the applicable registration statement, and each of the opinion and the “cold comfort” letter shall be in customary form and covering substantially the same matters with respect to such registration statement (and the prospectus included therein any supplement thereto) and as are customarily covered in opinions of issuer’s counsel and in accountants’ letters delivered to the underwriters in Underwritten Offerings of securities, such other matters as such underwriters may reasonably request;

(h) otherwise use its commercially reasonable efforts to comply with all applicable rules and regulations of the Commission, and make available to its security holders, as soon as reasonably practicable, an earnings statement covering the period of at least 12 months, but not more than 18 months, beginning with the first full calendar month after the effective date of such registration statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 promulgated thereunder;

(i) make available to the appropriate representatives of the Managing Underwriter and Selling Holders access to such information and Crosstex personnel as is reasonable and customary to enable such parties to establish a due diligence defense under the Securities Act; provided that Crosstex need not disclose any information to any such representative unless and until such representative has entered into a confidentiality agreement with Crosstex;

(j) cause all such Registrable Securities registered pursuant to this Agreement to be listed on each securities exchange or nationally recognized quotation system on which similar securities issued by Crosstex are then listed;

(k) use its commercially reasonable efforts to cause the Registrable Securities to be registered with or approved by such other governmental agencies or authorities as may be necessary by virtue of the business and operations of Crosstex to enable the Selling Holders to consummate the disposition of such Registrable Securities;

(l) provide a transfer agent and registrar for all Registrable Securities covered by such registration statement not later than the effective date of such registration statement; and

(m) enter into customary agreements and take such other actions as are reasonably requested by the Selling Holders or the underwriters, if any, in order to expedite or facilitate the disposition of such Registrable Securities.

Each Selling Holder, upon receipt of notice from Crosstex of the happening of any event of the kind described in subsection (e) of this Section 2.4, shall forthwith discontinue disposition of the Registrable Securities until such Selling Holder’s receipt of the copies of the supplemented or amended prospectus contemplated by subsection (e) of this Section 2.4 or until it is advised in writing by Crosstex that the use of the prospectus may be resumed, and has received copies of any additional or supplemental filings incorporated by reference in the prospectus, and, if so directed by Crosstex, such Selling Holder will, or will request the Managing Underwriter or underwriters, if any, to deliver to Crosstex (at Crosstex’s expense) all copies in their possession or control, other than permanent file copies then in such Selling Holder’s possession, of the prospectus and any prospectus supplement covering such Registrable Securities current at the time of receipt of such notice.

Section 2.5 Cooperation by Holders. Crosstex shall have no obligation to include in the Shelf Registration Statement units of a Holder or in a Piggyback Registration units of a Selling Holder who has failed to timely furnish such information which, in the opinion of counsel to Crosstex, is reasonably required in order for the registration statement or prospectus supplement, as applicable, to comply with the Securities Act.

Section 2.6 Restrictions on Public Sale by Holders of Registrable Securities. Each Holder of Registrable Securities who is included in the Shelf Registration Statement agrees not to effect any public sale or distribution of the Registrable Securities during the 30 calendar day period beginning on the date of a prospectus supplement filed with the Commission with respect to the pricing of an Underwritten Offering, or other prospectus (including any free writing prospectus) containing the terms of the pricing of such Underwritten Offering provided that the duration of the foregoing restrictions shall be no longer than the duration of the shortest restriction generally imposed by the underwriters on the officers or directors or any other unitholder of Crosstex on whom a restriction is imposed and provided further that such Selling Holder (together with any Affiliates that are Selling Holders) owns at least fifteen million ($15,000,000) of Registrable Securities, and Other Registration Securities, in the aggregate (determined by multiplying the number of Registrable Securities and Other Registrable Securities owned by the average of the closing price for Common Units for the ten (10) trading days preceding the date of such filing).

Section 2.7 Expenses.

(a) Certain Definitions. “Registration Expenses” means all expenses incident to Crosstex’s performance under or compliance with this Agreement to effect the registration of Registrable Securities in a Shelf Registration pursuant to Section 2.1, a Piggyback Registration pursuant to Section 2.2, or an Underwritten Offering pursuant to Section 2.3, and the disposition of such securities, including, without limitation, all registration, filing, securities exchange listing

and NASDAQ fees, all registration, filing, qualification and other fees and expenses of complying with securities or blue sky laws, fees of the National Association of Securities Dealers, Inc., transfer taxes and fees of transfer agents and registrars, all word processing, duplicating and printing expenses, the fees and disbursements of counsel and independent public accountants for Crosstex, including the expenses of any special audits or “cold comfort” letters required by or incident to such performance and compliance. Except as otherwise provided in Section 2.8 hereof, Crosstex shall not be responsible for legal fees incurred by Holders in connection with the exercise of such Holders’ rights hereunder. In addition, Crosstex shall not be responsible for any “Selling Expenses,” which means all underwriting fees, discounts and selling commissions and transfer taxes allocable to the sale of the Registrable Securities.

(b) Expenses. Crosstex will pay all reasonable Registration Expenses in connection with a Piggyback Registration or Underwritten Offering, whether or not any sale is made pursuant to the Piggyback Registration or Underwritten Offering. Each Selling Holder shall pay all Selling Expenses in connection with any sale of its Registrable Securities hereunder.

Section 2.8 Indemnification.

(a) By Crosstex. In the event of a registration of any Registrable Securities under the Securities Act pursuant to this Agreement, Crosstex will indemnify and hold harmless each Selling Holder thereunder, its directors, officers and managers, and each underwriter, pursuant to the applicable underwriting agreement with such underwriter, of Registrable Securities thereunder and each Person, if any, who controls such Selling Holder or underwriter within the meaning of the Securities Act and the Exchange Act, against any losses, claims, damages, expenses or liabilities (including reasonable attorneys’ fees and expenses) (collectively, “Losses”), joint or several, to which such Selling Holder or underwriter or controlling Person may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such Losses (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Shelf Registration Statement or any other registration statement contemplated by this Agreement, any preliminary prospectus or final prospectus contained therein, or any free writing prospectus related thereto, or any amendment or supplement thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in light of the circumstances under which they were made) not misleading, and will reimburse each such Selling Holder, its directors and officers, each such underwriter and each such controlling Person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such Loss or actions or proceedings; provided, however, that Crosstex will not be liable in any such case if and to the extent that any such Loss arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made in strict conformity with information furnished by such Selling Holder, such underwriter or such controlling Person in writing specifically for use in the Shelf Registration Statement or such other registration statement, or prospectus supplement, as applicable. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Selling Holder or any such director, officer or controlling Person, and shall survive the transfer of such securities by such Selling Holder.

(b) By Each Selling Holder. Each Selling Holder agrees severally and not jointly to indemnify and hold harmless Crosstex, its directors and officers, and each Person, if any, who controls Crosstex within the meaning of the Securities Act or of the Exchange Act to the same extent as the foregoing indemnity from Crosstex to the Selling Holders, but only with respect to information regarding such Selling Holder furnished in writing by or on behalf of such Selling Holder expressly for inclusion in the Shelf Registration Statement or prospectus supplement relating to the Registrable Securities, or any amendment or supplement thereto; provided, however, that the liability of each Selling Holder shall not be greater in amount than the dollar amount of the proceeds (net of any Selling Expenses) received by such Selling Holder from the sale of the Registrable Securities giving rise to such indemnification.

(c) Notice. Promptly after receipt by an indemnified party hereunder of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party other than under this Section 2.8. In any action brought against any indemnified party, it shall notify the indemnifying party of the commencement thereof. The indemnifying party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel reasonably satisfactory to such indemnified party and, after notice from the indemnifying party to such indemnified party of its election so to assume and undertake the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 2.8 for any legal expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation and of liaison with counsel so selected; provided, however, that, (i) if the indemnifying party has failed to assume the defense and employ counsel or (ii) 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 additional 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 reasonable expenses and fees of such separate counsel and other reasonable 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, includes a complete release from liability of, and does not contain any admission of wrong doing by, the indemnified party.

(d) Contribution. If the indemnification provided for in this Section 2.8 is held by a court or government agency of competent jurisdiction to be unavailable to Crosstex or any Selling Holder or is insufficient to hold them harmless in respect of any Losses, then each such indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such Losses in such proportion as is appropriate to reflect the relative fault of Crosstex on the one hand and of such Selling Holder on the other in connection with the statements or omissions which resulted in such Losses, as well as any other relevant equitable considerations; provided, however, that in no

event shall such Selling Holder be required to contribute an aggregate amount in excess of the dollar amount of proceeds (net of Selling Expenses) received by such Selling Holder from the sale of Registrable Securities giving rise to such indemnification. The relative fault of Crosstex on the one hand and each Selling Holder on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact has been made by, or relates to, information supplied by such party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just and equitable if contributions pursuant to this paragraph were to be determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the first sentence of this paragraph. The amount paid by an indemnified party as a result of the Losses referred to in the first sentence of this paragraph shall be deemed to include any legal and other expenses reasonably incurred by such indemnified party in connection with investigating or defending any Loss which is the subject of this paragraph. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who is not guilty of such fraudulent misrepresentation.

(e) Other Indemnification. The provisions of this Section 2.8 shall be in addition to any other rights to indemnification or contribution which an indemnified party may have pursuant to law, equity, contract or otherwise.

Section 2.9 Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the Commission that may permit the sale of the Registrable Securities to the public without registration, Crosstex agrees to use its commercially reasonable efforts to:

(a) Make and keep public information regarding Crosstex available, as those terms are understood and defined in Rule 144 of the Securities Act, at all times from and after the date hereof;

(b) File with the Commission in a timely manner all reports and other documents required of Crosstex under the Securities Act and the Exchange Act at all times from and after the date hereof; and

(c) So long as a Holder owns any Registrable Securities, furnish to such Holder forthwith upon request a copy of the most recent annual or quarterly report of Crosstex, and such other reports and documents so filed as such Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing such Holder to sell any such securities without registration.

Section 2.10 Transfer or Assignment of Registration Rights. The rights to cause Crosstex to register Registrable Securities granted to the Purchasers by Crosstex under this Article II may be transferred or assigned by the Purchasers to one or more transferee(s) or assignee(s) of such Registrable Securities, who (a) are Affiliates of such Purchaser, or (b) hold, collectively with its or their Affiliates, after giving effect to such transfer or assignment, at least fifteen million ($15,000,000) of Registrable Securities and Other Registrable Securities.

Crosstex shall be given written notice prior to any said transfer or assignment, stating the name and address of each such transferee and identifying the securities with respect to which such registration rights are being transferred or assigned, and each such transferee shall assume in writing responsibility for its obligations of the Purchasers under this Agreement.

Section 2.11 Limitation on Subsequent Registration Rights. From and after the date hereof, Crosstex shall not, without the prior written consent of the Holders of a 80% of the outstanding Registrable Securities, enter into any agreement with any current or future holder of any securities of Crosstex that would allow such current or future holder to require Crosstex to include securities in any registration statement filed by Crosstex on a basis that is superior in any way to the piggyback rights granted to the Purchasers hereunder.

Section 2.12 Aggregation of Registrable Securities. All Registrable Securities held or acquired by Persons who are Affiliates of one another shall be aggregated together for the purpose of determining the availability of any rights under this Agreement. In addition, all Registrable Securities held or acquired by Fiduciary / Claymore MLP Opportunity Fund and its Affiliates, on the one hand, and Energy Income and Growth Fund and its Affiliates, on the other hand, shall be aggregated together for the purpose of determining the availability of any rights under this Agreement.

Section 2.13 Registration Pursuant to the Securities Exchange Act. Upon the effectiveness of any Shelf Registration Statement that registers the Senior Subordinated Series C Units, Crosstex shall promptly file a Form 8-A with the Commission with respect to the Senior Subordinated Series C Units or otherwise cause the Senior Subordinated Series C Units to become registered under Section 12 of the Securities Exchange Act of 1934, as amended, and shall provide written notice of such registration to each Purchaser within one Business Day.

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 C Unit Purchase Agreement (the “Purchase Agreement”). Crosstex shall furnish to the Purchasers at the Closing an opinion of Baker Botts L.L.P., counsel for Crosstex, addressed to the Purchasers and dated the Closing Date in form satisfactory to Vinson & Elkins L.L.P., counsel for 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, 2005 (the “Annual Report”) [and Crosstex’s Quarterly Report on Form 10-Q for the quarters ended March 31, 2006 (the “10-Q”)]. 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 [ ] Common Units, [ ] Subordinated 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 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 and 17-607 of the Delaware Revised Uniform Limited Partnership Act (“Delaware LP Act”)).

(iii) To our knowledge, except as described in the Annual Report [and the 10-Q], 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

Exhibit B — Page 1

other securities of Crosstex other than those rights granted to the General Partner or any of its Affiliates (as such term is defined in the Partnership Agreement) under Section 7.12 of the Partnership Agreement.

(iv) Crosstex owns of record, directly or indirectly, all of the issued and outstanding equity interests of each of the Crosstex Subsidiaries (except Crosstex PC Gathering Company, J.V. [and Crosstex Dayton County Gathering, J.V.], free and clear of any Liens (A) in respect of which a financing statement under the Uniform Commercial Code naming any of the Crosstex Entities as debtor is on file in the office of the Secretary of State of Delaware or the office of the Secretary of State of Texas, (B) otherwise known to us, without independent investigation, other than those created by or arising under the Delaware LP Act, the Texas Revised Limited Partnership Act (the “Texas LP Act”) or the Delaware Limited Liability Company Act (the “Delaware LLC Act”), or (C) except for such Liens as may be imposed under the Senior Secured Credit Facility or the Crosstex Master Shelf Agreement, and all such ownership interests have been duly authorized, validly issued and are fully paid (to the extent required in the organizational documents of the Crosstex Subsidiaries, as applicable) and non-assessable (except as such nonassessability may be affected by matters described in Sections 17-303 and 17-607 of the Delaware LP Act or Sections 3.03, 5.02 and 6.07 of the Texas LP Act, as applicable).

(v) The Purchased Units to be issued and sold to the Purchasers by Crosstex pursuant to the Purchase Agreement and the Common Units underlying such Purchased Units, and the limited partner interests represented thereby, have been duly authorized under the Partnership Agreement and when issued and delivered to the Purchasers against payment therefor in accordance with the terms of the Purchase Agreement, will be validly issued, fully paid (to the extent required by the Partnership Agreement) and nonassessable (except as such nonassessability may be affected by matters described in Sections 17-303 and 17-607 of the Delaware LP Act).

(vi) None of the offering, issuance and sale by Crosstex of the Purchased Units, the conversion of the Purchased Units into Common Units, or the execution, delivery and performance of the Purchase Agreement and Registration Rights Agreement (A) constitutes or will constitute a violation of the Partnership Agreement or other organizational documents of any of the Crosstex Entities, (B) constitutes or will constitute a breach or violation of, or a default under (or an event which, with notice or lapse of time or both, would constitute such an event), any agreement filed or incorporated by reference as an exhibit to the Annual Report or (C) results or will result in any violation of the Delaware LP Act, the Delaware LLC Act, or U.S. federal law, which in the case of clauses (B) or (C) would be reasonably likely to have a Crosstex Material Adverse Effect; provided, however, that no opinion is expressed pursuant to this paragraph (vi) with respect to federal or state securities or anti-fraud statutes, rules or regulations.

(vii) Each of the Purchase Agreement, Registration Rights Agreement and Partnership Agreement has been duly authorized and validly executed and delivered on behalf of Crosstex or Crosstex Energy GP, L.P. party thereto, and is enforceable against such entity except as the enforceability thereof may be limited by (A) applicable bankruptcy, insolvency, fraudulent

Exhibit B — Page 2

transfer, reorganization, moratorium or similar laws from time to time in effect affecting creditors’ rights and remedies generally and by general principles of equity (regardless of whether such principles are considered in a proceeding in equity or at law) and (B) public policy, applicable law relating to fiduciary duties and indemnification and an implied covenant of good faith and fair dealing.

(viii) Except for the approvals required by the Commission in connection with Crosstex’s obligations under the Registration Rights Agreement, no authorization, consent, approval, waiver, license, qualification or filing with any U.S. federal or Delaware court, governmental agency or body having jurisdiction over the Crosstex Entities or any of their respective properties is required for the issuance and sale by Crosstex of the Purchased Units, the execution, delivery and performance of each of the Purchase Agreement and Registration Rights or the consummation of the transactions contemplated by the Purchase Agreement and Registration Rights Agreement, except those that have been obtained or as may be required under state securities or “Blue Sky” laws, as to which we do not express any opinion.

(ix) To our knowledge, there is no action, suit, proceeding or investigation pending against the Crosstex Entities before any court or governmental agency that questions the validity of the Purchase Agreement, Partnership Agreement or the Registration Rights Agreement, or the right of Crosstex to enter into any of the foregoing agreements.

(x) Crosstex is not an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

(xi) The Common Units issuable upon conversion of the Purchased Units and the limited partner interests represented thereby have been duly authorized by Crosstex pursuant to the Partnership Agreement and, upon issuance in accordance with the terms of Senior Subordinated Series C Units and the Partnership Agreement, will be validly issued, fully paid (to the extent required by the Partnership Agreement) and nonassessable (except as such nonassessability may be affected by matters described in Section 17-607 of the Delaware LP Act).

(xii) Assuming the accuracy of the representations and warranties of each Purchaser contained in the Purchase Agreement, the issuance and sale of the Purchased Units pursuant to the Purchase Agreement is exempt from registration requirements of the Securities Act of 1933, as amended.

(a) In addition to other rights provided by this Agreement or by applicable law, and except as limited by Section 3.4(b), each Limited Partner shall have the right, for a purpose reasonably related to such Limited Partner’s interest as a limited partner in the Partnership, upon reasonable written demand and at such Limited Partner’s own expense:

REDEMPTION OF PARTNERSHIP INTERESTS

Section 4.1 Certificates.

Upon the Partnership’s issuance of Common Units, Senior Subordinated Units, Senior Subordinated Series B Units, Senior Subordinated Series C Units or Subordinated Units to any Person, the Partnership may issue one or more Certificates in the name of such Person evidencing the number of such Units being so issued. In addition, (a) upon the General Partner’s request, the Partnership shall issue to it one or more Certificates in the name of the General Partner evidencing its interests in the Partnership and (b) upon the request of any Person owning Incentive Distribution Rights or any other Partnership Securities, the Partnership shall issue to such Person one or more certificates evidencing such Incentive Distribution Rights or other Partnership Securities. Certificates shall be executed on behalf of the Partnership by the Chairman of the Board, President or any Executive Vice President or Vice President and the Secretary or any Assistant Secretary of the General Partner. No Common Unit Certificate shall be valid for any purpose until it has been countersigned by the Transfer Agent; provided, however, that if the General Partner elects to issue Common Units in global form, the Common Unit Certificates shall be valid upon receipt of a certificate from the Transfer Agent certifying that the Common Units have been duly registered in accordance with the directions of the

Partnership and the Underwriters. Subject to the requirements of Sections 6.7(c), 6.8(c), 6.9(c) and 6.10(b), the Partners holding Certificates evidencing Senior Subordinated Units, Senior Subordinated Series B Units, Senior Subordinated Series C Units or Subordinated Units may exchange such Certificates for Certificates evidencing Common Units on or after the date on which such Senior Subordinated Units, Senior Subordinated Series B Units, Senior Subordinated Series C Units or Subordinated Units are converted into Common Units pursuant to the terms of Sections 5.8, 5.9, 5.10 and 5.11, respectively.

Section 4.2 Mutilated, Destroyed, Lost or Stolen Certificates.

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

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

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

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

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

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

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

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

Section 4.3 Record Holders.

The Partnership shall be entitled to recognize the Record Holder as the Partner or Assignee with respect to any Partnership Interest and, accordingly, shall not be bound to recognize any equitable or other claim to or interest in such Partnership Interest on the part of any other Person, regardless of whether the Partnership shall have actual or other notice thereof, except as otherwise provided by law or any applicable rule, regulation, guideline or requirement of any National Securities Exchange on which such Partnership Interests are listed for trading. Without limiting the foregoing, when a Person (such as a broker, dealer, bank, trust company or clearing corporation or an agent of any of the foregoing) is acting as nominee, agent or in some other representative capacity for another Person in acquiring and/or holding Partnership Interests, as between the Partnership on the one hand, and such other Persons on the other, such representative Person (a) shall be the Partner or Assignee (as the case may be) of record and beneficially, (b) must execute and deliver a Transfer Application and (c) shall be bound by this Agreement and shall have the rights and obligations of a Partner or Assignee (as the case may be) hereunder and as, and to the extent, provided for herein.

Section 4.4 Transfer Generally.

(a) The term “transfer,” when used in this Agreement with respect to a Partnership Interest, shall be deemed to refer to a transaction by which the General Partner assigns its General Partner Interest to another Person who becomes the general partner of the Partnership, by which the holder of a Limited Partner Interest assigns such Limited Partner Interest to another Person who is or becomes a Limited Partner or an Assignee, and includes a sale, assignment, gift, pledge, encumbrance, hypothecation, mortgage, exchange or any other disposition by law or otherwise.

(b) No Partnership Interest shall be transferred, in whole or in part, except in accordance with the terms and conditions set forth in this Article IV. Any transfer or purported transfer of a Partnership Interest not made in accordance with this Article IV shall be null and void.

(c) Nothing contained in this Agreement shall be construed to prevent a disposition by any partner or other owner of the General Partner of any or all of the partnership interests or other ownership interests of the General Partner.

Section 4.5 Registration and Transfer of Limited Partner Interests.

(a) The General Partner shall keep or cause to be kept on behalf of the Partnership a register in which, subject to such reasonable regulations as it may prescribe and subject to the provisions of Section 4.5(b), the Partnership will provide for the registration and transfer of Limited Partner Interests. The Transfer Agent is hereby appointed registrar and transfer agent for the purpose of registering Common Units and transfers of such Common Units as herein provided. The Partnership shall not recognize transfers of Certificates evidencing Limited Partner Interests unless such transfers are effected in the manner described in this Section 4.5. Upon surrender of a Certificate for registration of transfer of any Limited Partner Interests evidenced by a Certificate, and subject to the provisions of Section 4.5(b), the appropriate

officers of the General Partner on behalf of the Partnership shall execute and deliver, and in the case of Common Units, the Transfer Agent shall countersign and deliver, in the name of the holder or the designated transferee or transferees, as required pursuant to the holder’s instructions, one or more new Certificates evidencing the same aggregate number and type of Limited Partner Interests as was evidenced by the Certificate so surrendered.

(b) Except as otherwise provided in Section 4.9, the General Partner shall not recognize any transfer of Limited Partner Interests until the Certificates evidencing such Limited Partner Interests are surrendered for registration of transfer and such Certificates are accompanied by a Transfer Application duly executed by the transferee (or the transferee’s attorney-in-fact duly authorized in writing). No charge shall be imposed by the General Partner for such transfer; provided, that as a condition to the issuance of any new Certificate under this Section 4.5, the General Partner may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed with respect thereto.

(c) Limited Partner Interests may be transferred only in the manner described in this Section 4.5. The transfer of any Limited Partner Interests and the admission of any new Limited Partner shall not constitute an amendment to this Agreement.

(d) Until admitted as a Substituted Limited Partner pursuant to Section 10.2, the Record Holder of a Limited Partner Interest shall be an Assignee in respect of such Limited Partner Interest. Limited Partners may include custodians, nominees or any other individual or entity in its own or any representative capacity.

(e) A transferee of a Limited Partner Interest who has completed and delivered a Transfer Application shall be deemed to have (i) requested admission as a Substituted Limited Partner, (ii) agreed to comply with and be bound by and to have executed this Agreement, (iii) represented and warranted that such transferee has the right, power and authority and, if an individual, the capacity to enter into this Agreement, (iv) granted the powers of attorney set forth in this Agreement and (v) given the consents and approvals and made the waivers contained in this Agreement.

(f) The General Partner and its Affiliates shall have the right at any time to transfer their Subordinated Units and Common Units (whether issued upon conversion of the Subordinated Units or otherwise) to one or more Persons.

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

(a) Subject to Section 4.6(c) below, prior to December 31, 2012, the General Partner shall not transfer all or any part of its General Partner Interest to a Person unless such transfer (i) has been approved by the prior written consent or vote of the holders of at least a majority of the Outstanding Common Units (excluding Common Units held by the General Partner and its Affiliates) or (ii) is of all, but not less than all, of its General Partner Interest to (A) an Affiliate of the General Partner (other than an individual) or (B) another Person (other than an individual) in connection with the merger or consolidation of the General Partner with or into another Person (other than an individual) or the transfer by the General Partner of all or substantially all of its assets to another Person (other than an individual).

(b) Subject to Section 4.6(c) below, on or after December 31, 2012, the General Partner may transfer all or any of its General Partner Interest without Unitholder approval.

(c) Notwithstanding anything herein to the contrary, no transfer by the General Partner of all or any part of its General Partner Interest to another Person shall be permitted unless (i) the transferee agrees to assume the rights and duties of the General Partner under this Agreement and to be bound by the provisions of this Agreement, (ii) the Partnership receives an Opinion of Counsel that such transfer would not result in the loss of limited liability of any Limited Partner or of any limited partner of the Operating Partnership or cause the Partnership or the Operating Partnership to be treated as an association taxable as a corporation or otherwise to be taxed as an entity for federal income tax purposes (to the extent not already so treated or taxed) and (iii) such transferee also agrees to purchase all (or the appropriate portion thereof, if applicable) of the partnership or membership interest of the General Partner as the general partner or managing member, if any, of each other Group Member. In the case of a transfer pursuant to and in compliance with this Section 4.6, the transferee or successor (as the case may be) shall, subject to compliance with the terms of Section 10.3, be admitted to the Partnership as the General Partner immediately prior to the transfer of the Partnership Interest, and the business of the Partnership shall continue without dissolution.

Section 4.7 Transfer of Incentive Distribution Rights.

Prior to December 31, 2012, a holder of Incentive Distribution Rights may transfer any or all of the Incentive Distribution Rights held by such holder without any consent of the Unitholders (a) to an Affiliate of such holder (other than an individual) or (b) to another Person (other than an individual) in connection with (i) the merger or consolidation of such holder of Incentive Distribution Rights with or into such other Person, (ii) the transfer by such holder of all or substantially all of its assets to such other Person or (iii) the sale of all or substantially all of the equity interests of such holder to such other Person. Any other transfer of the Incentive Distribution Rights prior to December 31, 2012, shall require the prior approval of holders of at least a majority of the Outstanding Common Units (excluding Common Units held by the General Partner and its Affiliates). On or after December 31, 2012, the General Partner or any other holder of Incentive Distribution Rights may transfer any or all of its Incentive Distribution Rights without Unitholder approval. Notwithstanding anything herein to the contrary, no transfer of Incentive Distribution Rights to another Person shall be permitted unless the transferee agrees to be bound by the provisions of this Agreement.

Section 4.8 Restrictions on Transfers.

(a) Except as provided in Section 4.8(d) below, but notwithstanding the other provisions of this Article IV, no transfer of any Partnership Interests shall be made if such transfer would (i) violate the then applicable federal or state securities laws or rules and regulations of the Commission, any state securities commission or any other governmental authority with jurisdiction over such transfer, (ii) terminate the existence or qualification of the Partnership or the Operating Partnership under the laws of the jurisdiction of its formation, or (iii) cause the Partnership or the Operating Partnership to be treated as an association taxable as a corporation or otherwise to be taxed as an entity for federal income tax purposes (to the extent not already so treated or taxed).

(b) The General Partner may impose restrictions on the transfer of Partnership Interests if a subsequent Opinion of Counsel determines that such restrictions are necessary to avoid a significant risk of any Group Member becoming taxable as a corporation or otherwise to be taxed as an entity for federal income tax purposes. The restrictions may be imposed by making such amendments to this Agreement as the General Partner may determine to be necessary or appropriate to impose such restrictions; provided, however, that any amendment that the General Partner believes, in the exercise of its reasonable discretion, could result in the delisting or suspension of trading of any class of Limited Partner Interests on the principal National Securities Exchange on which such class of Limited Partner Interests is then traded must be approved, prior to such amendment being effected, by the holders of at least a majority of the Outstanding Limited Partner Interests of such class.

(c) The transfer of a Senior Subordinated Unit, a Senior Subordinated Series B Unit, a Senior Subordinated Series C Unit or a Subordinated Unit that has converted into a Common Unit shall be subject to the restrictions imposed by Sections 6.7(c), 6.8(c), 6.9(c) and 6.10(b).

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

Section 4.9 Citizenship Certificates; Non-citizen Assignees.

(a) If any Group Member is or becomes subject to any federal, state or local law or regulation that, in the reasonable determination of the General Partner, creates a substantial risk of cancellation or forfeiture of any property in which the Group Member has an interest based on the nationality, citizenship or other related status of a Limited Partner or Assignee, the General Partner may request any Limited Partner or Assignee to furnish to the General Partner, within 30 days after receipt of such request, an executed Citizenship Certification or such other information concerning his nationality, citizenship or other related status (or, if the Limited Partner or Assignee is a nominee holding for the account of another Person, the nationality, citizenship or other related status of such Person) as the General Partner may request. If a Limited Partner or Assignee fails to furnish to the General Partner within the aforementioned 30-day period such Citizenship Certification or other requested information or if upon receipt of such Citizenship Certification or other requested information the General Partner determines, with the advice of counsel, that a Limited Partner or Assignee is not an Eligible Citizen, the Partnership Interests owned by such Limited Partner or Assignee shall be subject to redemption in accordance with the provisions of Section 4.10. In addition, the General Partner may require that the status of any such Partner or Assignee be changed to that of a Non-citizen Assignee and, thereupon, the General Partner shall be substituted for such Non-citizen Assignee as the Limited Partner in respect of his Limited Partner Interests.

(b) The General Partner shall, in exercising voting rights in respect of Limited Partner Interests held by it on behalf of Non-citizen Assignees, distribute the votes in the same ratios as the votes of Partners (including without limitation the General Partner) in respect of Limited Partner Interests other than those of Non-citizen Assignees are cast, either for, against or abstaining as to the matter.

(c) Upon dissolution of the Partnership, a Non-citizen Assignee shall have no right to receive a distribution in kind pursuant to Section 12.4 but shall be entitled to the cash equivalent thereof, and the Partnership shall provide cash in exchange for an assignment of the Non-citizen Assignee’s share of the distribution in kind. Such payment and assignment shall be treated for Partnership purposes as a purchase by the Partnership from the Non-citizen Assignee of his Limited Partner Interest (representing his right to receive his share of such distribution in kind).

(d) At any time after he can and does certify that he has become an Eligible Citizen, a Non-citizen Assignee may, upon application to the General Partner, request admission as a Substituted Limited Partner with respect to any Limited Partner Interests of such Non-citizen Assignee not redeemed pursuant to Section 4.10, and upon his admission pursuant to Section 10.2, the General Partner shall cease to be deemed to be the Limited Partner in respect of the Non-citizen Assignee’s Limited Partner Interests.

Section 4.10 Redemption of Partnership Interests of Non-citizen Assignees.

(a) If at any time a Limited Partner or Assignee fails to furnish a Citizenship Certification or other information requested within the 30-day period specified in Section 4.9(a), or if upon receipt of such Citizenship Certification or other information the General Partner determines, with the advice of counsel, that a Limited Partner or Assignee is not an Eligible Citizen, the Partnership may, unless the Limited Partner or Assignee establishes to the satisfaction of the General Partner that such Limited Partner or Assignee is an Eligible Citizen or has transferred his Partnership Interests to a Person who is an Eligible Citizen and who furnishes a Citizenship Certification to the General Partner prior to the date fixed for redemption as provided below, redeem the Partnership Interest of such Limited Partner or Assignee as follows:

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

(ii) The aggregate redemption price for Redeemable Interests shall be an amount equal to the Current Market Price (the date of determination of which shall be the date fixed for redemption) of Limited Partner Interests of the class to be so redeemed multiplied by the number of Limited Partner Interests of each such class included among the Redeemable Interests. The redemption price shall be paid, in the discretion of the General Partner, in cash or by delivery of a promissory note of the Partnership in the principal amount of the redemption price, bearing interest at the rate of 10% annually and payable in three equal annual installments of principal together with accrued interest, commencing one year after the redemption date.

(iii) Upon surrender by or on behalf of the Limited Partner or Assignee, at the place specified in the notice of redemption, of the Certificate evidencing the Redeemable Interests, duly endorsed in blank or accompanied by an assignment duly executed in blank, the Limited Partner or Assignee or his duly authorized representative shall be entitled to receive the payment therefor.

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

(b) The provisions of this Section 4.10 shall also be applicable to Limited Partner Interests held by a Limited Partner or Assignee as nominee of a Person determined to be other than an Eligible Citizen.

(c) Nothing in this Section 4.10 shall prevent the recipient of a notice of redemption from transferring his Limited Partner Interest before the redemption date if such transfer is otherwise permitted under this Agreement. Upon receipt of notice of such a transfer, the General Partner shall withdraw the notice of redemption, provided the transferee of such Limited Partner Interest certifies to the satisfaction of the General Partner in a Citizenship Certification delivered in connection with the Transfer Application that he is an Eligible Citizen. If the transferee fails to make such certification, such redemption shall be effected from the transferee on the original redemption date.

ARTICLE V

CAPITAL CONTRIBUTIONS AND ISSUANCE OF PARTNERSHIP INTERESTS

Section 5.1 Organizational Contributions.

In connection with the formation of the Partnership under the Delaware Act, the General Partner made an initial Capital Contribution to the Partnership in the amount of $20.00, for a 2% General Partner interest in the Partnership and has been admitted as the General Partner of the Partnership, and the Organizational Limited Partner made an initial Capital Contribution to the Partnership in the amount of $980.00 for a 98% Limited Partner interest in the Partnership and has been admitted as a Limited Partner of the Partnership. As of the Closing Date, the interest of the Organizational Limited Partner shall be redeemed as provided in the Closing Contribution Agreement; the initial Capital Contributions of the Organizational Limited Partner shall thereupon be refunded; and the Organizational Limited Partner shall cease to be a Limited Partner of the Partnership. Ninety-eight percent of any interest or other profit that may have resulted from the investment or other use of such initial Capital Contributions shall be allocated and distributed to the Organizational Limited Partner, and the balance thereof shall be allocated and distributed to the General Partner. On December 6, 2002 and pursuant to the First Contribution Agreement, among other things, (i) Crosstex Energy, Inc. and Crosstex Texas Inc. transferred their interests in the predecessor to the Operating Partnership to the Partnership in exchange for a limited partner interest in the Partnership and (ii) Crosstex Texas Inc. transferred its limited partner interest in the Partnership to the General Partner.

Section 5.2 Contributions by the General Partner and its Affiliates.

(a) On the Closing Date and pursuant to the Closing Contribution Agreement, (i) the General Partner’s initial general partner interest and its limited partner interest was converted into (A) the General Partner Interest, subject to all of the rights, privileges and duties of the General Partner under this Agreement, and (B) the Incentive Distribution Rights, and (ii) Crosstex Energy, Inc.’s limited partner interest was converted (taking into account the effect of the Unit Split) into (A) 666,000 Common Units, (B) 9,334,000 Subordinated Units and (C) the right to receive $2.5 million from the Partnership on the Closing Date.

(b) Upon the issuance of any additional Limited Partner Interests by the Partnership (other than the issuance of the Common Units issued in the Initial Offering and other than the issuance of the Common Units issued pursuant to the Over-Allotment Option), the General Partner shall be required to make additional Capital Contributions equal to 2/98ths of any amount contributed to the Partnership by the Limited Partners in exchange for the additional Limited Partner Interests issued to such Limited Partners. Except as set forth in the immediately preceding sentence and Article XII, the General Partner shall not be obligated to make any additional Capital Contributions to the Partnership.

Section 5.3 Contributions by Initial Limited Partners.

(a) On the Closing Date and pursuant to the Underwriting Agreement, each Underwriter contributed to the Partnership cash in an amount equal to the Issue Price per Initial Common Unit, multiplied by the number of Common Units specified in the Underwriting Agreement to be purchased by such Underwriter at the Closing Date in exchange for such number of Common Units.

(b) Upon the exercise of the Over-Allotment Option, each Underwriter contributed to the Partnership cash in an amount equal to the Issue Price per Initial Common Unit, multiplied by the number of Common Units specified in the Underwriting Agreement to be purchased by such Underwriter at the Option Closing Date in exchange for such number of Common Units.

(c) No Limited Partner Interests were issued or issuable as of or at the Closing Date other than (i) the Common Units issuable pursuant to subparagraph (a) hereof in aggregate number equal to 4,000,000, (ii) the “Additional Units” as such term is used in the Underwriting Agreement in an aggregate number up to 600,000 issuable upon exercise of the Over-Allotment Option pursuant to subparagraph (b) hereof, (iii) the 666,000 Common Units issuable to Crosstex Energy, Inc. pursuant to Section 5.2 hereof, (iv) the 9,334,000 Subordinated Units issuable to Crosstex Energy, Inc. pursuant to Section 5.2 hereof, and (v) the Incentive Distribution Rights.

Section 5.4 Interest and Withdrawal.

No interest shall be paid by the Partnership on Capital Contributions. No Partner or Assignee shall be entitled to the withdrawal or return of its Capital Contribution, except to the extent, if any, that distributions made pursuant to this Agreement or upon termination of the Partnership may be considered as such by law and then only to the extent provided for in this Agreement. Except to the extent expressly provided in this Agreement, no Partner or Assignee shall have priority over any other Partner or Assignee either as to the return of Capital

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

Section 5.5 Capital Accounts.

The provisions of this Section 5.5 are subject to Section 5.5(e) which addresses the effect of the Unit Split.

(a) The balance of the Capital Account of an Underwriter (and derivatively of the holder of one or more Common Units who purchases directly or indirectly from an Underwriter) in respect of each Common Unit acquired thereby pursuant to the Underwriting Agreement at the Closing or by reason of the exercise of the Over-Allotment Option shall be the Issue Price for an Initial Common Unit, and the balance of the Capital Account of each such Underwriter shall be the product of such initial balance for a Common Unit multiplied by the number of Common Units held thereby. The initial balance of the Capital Account of the General Partner and of its Affiliates shall be the amount of cash and the Net Agreed Value of the property of the Partnership (that is, the property for which the Partnership computes a Carrying Value) that would be distributed to the General Partner and any such affiliate pursuant to this Agreement prior to the contributions that are to be made pursuant to Section 5.3 hereof if such cash and Net Agreed Value were distributed only to the General Partner Interest and the Units held by the General Partner and its Affiliates in proportion to the relative right of such interests to distributions that are made 2% to the General Partner Interest and 98% to the holders of Units, Pro Rata. The balance of the Capital Accounts of the Common Units held by such a Person shall be determined as though the aggregate amount that was deemed distributed with respect to the Units held thereby was distributed first to such Common Units, Pro Rata until the Initial Issue Price was distributed to each Common Unit held thereby. The balance of the Capital Accounts of the Subordinated Units held by such a Person shall be the portion of such cash and Net Agreed Value that could have been, but was not, applied pursuant to the preceding sentence in determining the Capital Account balance of the Common Units. Any Common Unit the Capital Account balance of which is less than the Initial Issue Price shall be treated as a converted Subordinated Unit for purposes of Section 5.5(c)(ii) and Section 6.9(b) and as a Final Subordinated Unit for purposes of Section 6.1(d)(ix). The initial Capital Account balance in respect of each Senior Subordinated Unit shall be the Issue Price for such Senior Subordinated Unit, and the initial Capital Account balance of each holder of Senior Subordinated Units in respect of all Senior Subordinated Units held shall be the product of such initial balance for a Senior Subordinated Unit multiplied by the number of Senior Subordinated Units held thereby. The initial Capital Account balance in respect of each Senior Subordinated Series B Unit shall be the Issue Price for such Senior Subordinated Series B Unit, and the initial Capital Account balance of each holder of Senior Subordinated Series B Units in respect of all Senior Subordinated Series B Units held shall be the product of such initial balance for a Senior Subordinated Series B Unit multiplied by the number of Senior Subordinated Series B Units held thereby. The initial Capital Account balance in respect of each Senior Subordinated Series C Unit shall be the Issue Price for such Senior Subordinated Series C Unit, and the initial Capital Account balance of each holder of Senior Subordinated Series C Units in respect of all Senior Subordinated Series C Units held shall be the product of such initial balance for a Senior Subordinated Series C Unit multiplied by the number of Senior Subordinated Series C Units held

thereby. The initial Capital Account balance of any other Partner shall be zero. Thereafter, the Capital Account of each Partner shall be increased by (i) the amount of cash and the Net Agreed Value of property contributed to the Partnership by such Partner pursuant to this Agreement and (ii) all items of Partnership income and gain allocated to such Partner pursuant to Section 6.1, and it shall be decreased by (x) the amount of cash or Net Agreed Value of all distributions of cash or property made to such Partner pursuant to this Agreement and (y) all items of Partnership deduction and loss allocated to such Partner pursuant to Section 6.1. The General Partner may in connection with the issuance of Partnership Interests after the Initial Offering and the exercise (or not) of the Over-Allotment Option adjust the balance of the Capital Account of any Partner so as to preserve the agreed economic relationship between the Partnership Interests that are so issued and the Partnership Interests that were outstanding prior to such issuance; provided that the economic relationships between the Partnership Interests that were outstanding prior to such issuance are not changed thereby. Any such adjustment shall be recorded in the records of the Partnership.

(b) The items of income, gain, loss or deduction that are recognized by the Partnership for federal income tax purposes during a taxable period of the Partnership shall be adjusted as is set out in this Section 5.5(b) and shall then be allocated among the Partners as is provided in Section 6.1.

(i) The Partnership shall be treated as owning directly its share (as determined by the General Partner) of all property owned by the Operating Partnership or any other Subsidiary that is, in each case, classified as a partnership or is disregarded for federal income tax purposes.

(ii) All fees and other expenses incurred by the Partnership to promote the sale of (or to sell) a Partnership Interest that cannot either be deducted or amortized under Section 709 of the Code shall be treated as an item of deduction at the time such fees and other expenses are incurred. Any such fees and expenses that were incurred in connection with the Initial Offering shall be deemed to have been incurred in the first taxable period of the Partnership that ends after the Initial Offering. Any underwriting discount or commission that is allowed to an Underwriter by reason of the Underwriting Agreement or the Over-Allotment Option, any difference between the Initial Unit Price and the Issue Price of the Senior Subordinated Units, any difference between the Initial Unit Price and the Issue Price of the Senior Subordinated Series B Units and any difference between the Initial Unit Price and the Issue Price of the Senior Subordinated Series C Units shall not be treated as an item of deduction of the Partnership that is allocable pursuant to Section 6.1.

(iii) The computation of items of income, gain, loss and deduction shall be made without regard to any election under Section 754 of the Code; provided that if an adjustment to the adjusted tax basis of any Partnership asset is required pursuant to Section 734(b) or 743(b) of the Code, pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts, the amount of such adjustment shall be treated as an item of income or deduction, as the case may be, at the time of the adjustment, and the Carrying Value of each Partnership asset in respect of which there was such an adjustment shall also be adjusted at that time.

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

(v) Any deductions for depreciation, cost recovery or amortization that are attributable to any Partnership property shall be determined as if the adjusted basis of such property were equal to the Carrying Value thereof and by using a rate of depreciation, cost recovery or amortization derived from the same method and useful life (or, if applicable, the remaining useful life) as is applied for federal income tax purposes and appropriately taking into account the length of any short taxable period of the Partnership; provided, however, that, if the Partnership property has a zero adjusted basis for federal income tax purposes, depreciation, cost recovery or amortization deductions shall be determined using any reasonable method that the General Partner may adopt. Any deduction for depreciation, cost recovery or amortization in respect of Partnership property that is determined pursuant to this Section 5.5(b) shall reduce the Carrying Value of that Partnership property as of the end of the taxable period of the Partnership in which such deduction was recognized. Notwithstanding the foregoing portion of this Section 5.5(b)(v), such deductions for depreciation, cost recovery, or amortization shall be determined with respect to any portion of such Carrying Value with respect to which Treasury Regulation Section 1.704-3(d) remedial allocations are to be made (including reverse section 704(c) allocations that are to be made as Treasury Regulation Section 1.704-3(d) remedial allocations) pursuant to provisions hereof in accordance with a method that is permitted by such Treasury Regulation Section 1.704-3(d) and that is selected by the General Partner.

(vi) If the Partnership’s adjusted basis in property is reduced for federal income tax purposes pursuant to Section 48(q)(1) or 48(q)(3) of the Code, the amount of such reduction shall be an additional depreciation or cost recovery deduction in the year such property is placed in service at the time of such reduction and shall be treated as a reduction in the Carrying Value of such property. Any restoration of such basis pursuant to Section 48(q)(2) of the Code shall be an item of income at the time of such restoration and shall be treated as an increase in the Carrying Value of such property at the time of such restoration.

(vii) Any items of gain and loss that are determined pursuant to Section 5.5(d) hereof shall be treated as items of income and deduction, respectively, that are recognized in the taxable period of the Partnership that ends with the event that causes the determination of such gain or loss. An item of income of the Partnership that is described in Section 705(a)(1)(B) of the Code (with respect to items of income that are exempt from tax) shall be treated as an item of income for the purpose of this Section 5.5(b), and an item of expense of the Partnership that is described in Section 705(a)(2)(B) of the Code (with respect to expenditures that are deductible and not chargeable to capital accounts), shall be treated as an item of deduction for the purpose of this Section 5.5(b).

(viii) A taxable period of the Partnership includes a taxable year of the Partnership. The portion of a taxable period of the Partnership that ends with the Closing

Date or with an event in respect of which there is an adjustment to Carrying Values pursuant to Section 5.5(d) hereof shall be treated as the end of a taxable period of the Partnership. The portion of such taxable year of the Partnership that begins immediately thereafter shall be treated as a taxable period for purposes of the preceding sentence with the result that each taxable year of the Partnership may contain one or more taxable periods of the Partnership. The items of income, gain, loss and deduction of the Partnership that are recognized for federal, state or local income tax purposes prior to the Closing Date shall not be allocated pursuant to this Agreement.

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

(ii) Immediately prior to the transfer of a Senior Subordinated Unit, a Senior Subordinated Series B Unit, a Senior Subordinated Series C Unit or a Subordinated Unit, or of a Senior Subordinated Unit, a Senior Subordinated Series B Unit, Senior Subordinated Series C Unit or a Subordinated Unit that has converted into a Common Unit pursuant to Sections 5.8, 5.9, 5.10 or 5.11 (other than a transfer to an Affiliate unless the General Partner elects to have this Section 5.5(c)(ii) apply with respect to such transfer), the Capital Account maintained for such Person with respect to its Senior Subordinated Units, Senior Subordinated Series B Units, Senior Subordinated Series C Units, Subordinated Units, converted Senior Subordinated Units, converted Senior Subordinated Series B Units, converted Senior Subordinated Series C Units or converted Subordinated Units, as the case may be, will (A) first, be allocated to such Units that are to be transferred so that the balance of the Capital Account thereof shall be equal to the then balance of the Capital Account of an Initial Common Unit, and (B) second, shall be allocated to any Senior Subordinated Units, Senior Subordinated Series B Units, Senior Subordinated Series C Units, Subordinated Units, converted Senior Subordinated Units, converted Senior Subordinated Series B Units, converted Senior Subordinated Series C Units or converted Subordinated Units that are retained. The amount so allocated to each class of Units shall thereafter be the balance of the Capital Account thereof.

(d) (i) On an issuance of additional Partnership Interests for cash (excluding however any issuance of Units pursuant to the Over-Allotment Option) or other property or the conversion of a General Partner’s Combined Interest to Common Units pursuant to Section 11.3(b), the General Partner may cause any Unrealized Gain or Unrealized Loss attributable to Partnership property to be recognized as if there had been a sale of all such property immediately prior to such issuance in which event the Carrying Value of each Partnership property shall be adjusted as of the beginning of the next taxable period to be equal to such fair market value; provided that the General Partner shall cause Unrealized Gain or Unrealized Loss to be recognized and Carrying Values to be adjusted if doing so would cause Corrective Allocations to be made pursuant to Section 6.1(d)(xi). In determining such Unrealized Gain or Unrealized Loss, the aggregate cash amount and fair market value of all Partnership assets immediately prior to the issuance of additional Partnership Interests shall be determined by the General Partner using such reasonable method of valuation as it may adopt; provided, however, that the General Partner, in arriving at such valuation, must take fully into account the fair market value of the Partnership Interests of all Partners at such time. The General Partner shall allocate such aggregate value among the assets of the Partnership (in such manner as it determines in its

discretion to be reasonable). Any adjustments that are made under this paragraph in connection with the issuance of the Senior Subordinated Units shall be based on the Initial Unit Price of the Senior Subordinated Units. Any adjustments that are made under this paragraph in connection with the issuance of the Senior Subordinated Series B Units shall be based on the Initial Unit Price of the Senior Subordinated Series B Units.

(ii) Immediately prior to any distribution to a Partner (other than a distribution of cash that is not in redemption or retirement of a Partnership Interest), the General Partner may cause any Unrealized Gain or Unrealized Loss attributable to each Partnership property to be recognized as if there had been a sale of such property immediately prior to such distribution in which event the Carrying Value of each Partnership property shall be as of the beginning of the next taxable period equal to the fair market value thereof; provided that the General Partner shall cause Unrealized Gain or Unrealized Loss to be recognized and Carrying Values to be adjusted if doing so would permit Corrective Allocations to be made pursuant to Section 6.1(d)(xi). In determining such Unrealized Gain or Unrealized Loss the aggregate cash amount and fair market value of all Partnership assets immediately prior to a distribution shall (A) in the case of a distribution that is not made pursuant to Section 12.4 be determined and allocated in the same manner as that provided in Section 5.5(d)(i) or (B) in the case of a liquidating distribution pursuant to Section 12.4, be determined and allocated by the Liquidator using such reasonable method of valuation as it may adopt.

(iii) After any adjustment of Carrying Values pursuant to Section 5.5(d)(i) or 5.5(d)(ii), the General Partner shall determine the way, if any, in which such changes in Carrying Value shall affect the allocations for federal, state and local income tax purposes pursuant to Section 6.2 of the items of income, gain, loss, deduction and credit that are recognized by the Partnership for such purposes. Any such determination shall be entered in the records of the Partnership.

(e) The balance of the Capital Account of a Partner (which is the sum of the balances of the Capital Account of all the Units or other Partnership Interests that are owned by the Partner) shall be unchanged by reason of the Unit Split; but the balance of a Capital Account of a Common Unit or of a Subordinated Unit at the end of the first taxable period that ends after the Unit Split shall be 50 percent of the amount that would have been the balance thereof at that time if the Unit Split had not occurred. In particular, the balance of a Capital Account of a Common Unit and of a Subordinated Unit shall be determined pursuant to this Section 5.5 and other provisions of this Agreement as if the Unit Split had been effective immediately before the initial application of this Section 5.5 and by giving effect at that time to the reduction in Initial Unit Price that occurs with the amendments to this Agreement that implement the Unit Split. The foregoing shall be applied so that the effect of the Unit Split is to double the number of Common Units and the number of Subordinated Units that are held by a person who is a holder of Common Units or who is a holder of Subordinated Units prior to the record date for the Unit Split without any change being effected in the relative rights of any such Partner or Assignee, such as the right thereof to distributions. The General Partner may make such other changes to the determination of Capital Account balances as are necessary in its judgment to achieve the effect of the Unit Split that is described in the preceding sentence.

Section 5.6 Issuances of Additional Partnership Securities.

(a) Subject to Section 5.7, the Partnership may issue additional Partnership Securities and options, rights, warrants and appreciation rights relating to the Partnership Securities for any Partnership purpose at any time and from time to time to such Persons for such consideration and on such terms and conditions as shall be established by the General Partner in its sole discretion, all without the approval of any Limited Partners.

(b) Each additional Partnership Security authorized to be issued by the Partnership pursuant to Section 5.6(a) may be issued in one or more classes, or one or more series of any such classes, with such designations, preferences, rights, powers and duties (which may be senior to existing classes and series of Partnership Securities), as shall be fixed by the General Partner in the exercise of its sole discretion, including (i) the right to share Partnership profits and losses or items thereof; (ii) the right to share in Partnership distributions (the specification of which may include an amendment of Section 6.1); (iii) the rights upon dissolution and liquidation of the Partnership; (iv) whether, and the terms and conditions upon which, the Partnership may redeem the Partnership Security; (v) whether such Partnership Security is issued with the privilege of conversion or exchange and, if so, the terms and conditions of such conversion or exchange; (vi) the terms and conditions upon which each Partnership Security will be issued, evidenced by certificates and assigned or transferred; (vii) the number of Units to which such Partnership Securities are equivalent for the purpose of determining Percentage Interest (and only for such purpose); and (viii) the right, if any, of each such Partnership Security to vote on Partnership matters, including matters relating to the relative rights, preferences and privileges of such Partnership Security.

(c) The General Partner is hereby authorized and directed to take all actions that it deems necessary or appropriate in connection with (i) each issuance of Partnership Securities and options, rights, warrants and appreciation rights relating to Partnership Securities pursuant to this Section 5.6, (ii) the conversion of the General Partner Interest or any Incentive Distribution Rights into Units pursuant to the terms of this Agreement, (iii) the admission of Additional Limited Partners and (iv) all additional issuances of Partnership Securities. The General Partner is further authorized and directed to specify the relative rights, powers and duties of the holders of the Units or other Partnership Securities being so issued. The General Partner shall do all things necessary to comply with the Delaware Act and is authorized and directed to do all things it deems to be necessary or advisable in connection with any future issuance of Partnership Securities or in connection with the conversion of the General Partner Interest or any Incentive Distribution Rights into Units pursuant to the terms of this Agreement, including compliance with any statute, rule, regulation or guideline of any federal, state or other governmental agency or any National Securities Exchange on which the Units or other Partnership Securities are listed for trading.

Section 5.7 Limitations on Issuance of Additional Partnership Securities.

The issuance of Partnership Securities pursuant to Section 5.6 shall be subject to the following restrictions and limitations:

(a) During the Subordination Period, the Partnership shall not issue (and shall not issue any options, rights, warrants or appreciation rights relating to) an aggregate of more than 2,333,000 (plus an amount, if any, equal to one half of the number of Units issued pursuant to the Over-Allotment Option, if and to the extent exercised) additional Parity Units without the prior approval of the holders of a Unit Majority; provided that any Common Units that were issued prior to the Unit Split shall be counted as two Common Units for purposes of this Section 5.7. In applying this limitation, there shall be excluded Common Units and other Parity Units issued (A) in connection with the exercise of the Over-Allotment Option, (B) in accordance with Sections 5.7(b), 5.7(c) and 5.7(d), (C) upon conversion of Subordinated Units pursuant to Section 5.10, (D) upon conversion of the General Partner Interest or any Incentive Distribution Rights pursuant to Section 11.3(b), (D) pursuant to the employee benefit plans of the General Partner, the Partnership or any other Group Member, (E) upon a conversion or exchange of Parity Units issued after the date hereof into Common Units or other Parity Units; provided that the total amount of Available Cash required to pay the aggregate Minimum Quarterly Distribution on all Common Units and all Parity Units does not increase as a result of this conversion or exchange, and (F) in the event of a combination or subdivision of Common Units.

(b) The Partnership may also issue an unlimited number of Parity Units, prior to the end of the Subordination Period and without the prior approval of the Unitholders, if such issuance occurs (i) in connection with an Acquisition or a Capital Improvement or (ii) within 365 days of, and the net proceeds from such issuance are used to repay debt incurred in connection with, an Acquisition or a Capital Improvement, in each case where such Acquisition or Capital Improvement involves assets that, if acquired by the Partnership as of the date that is one year prior to the first day of the Quarter in which such Acquisition is to be consummated or such Capital Improvement is to be completed, would have resulted, on a pro forma basis, in an increase in:

(A) the amount of Adjusted Operating Surplus generated by the Partnership on a per-Unit basis (for all Outstanding Units) with respect to the most recently completed four-Quarter period (on a pro forma basis as described below) as compared to

(B) the actual amount of Adjusted Operating Surplus generated by the Partnership on a per-Unit basis (for all Outstanding Units) (excluding Adjusted Operating Surplus attributable to the Acquisition or Capital Improvement) with respect to such most recently completed four-Quarter period.

The General Partner’s good faith determination that such an increase would have resulted shall be conclusive. If the issuance of Parity Units with respect to an Acquisition or Capital Improvement occurs within the first four full Quarters after the Closing Date, then Adjusted Operating Surplus as used in clauses (A) (subject to the succeeding sentence) and (B) above shall be calculated (i) for each Quarter, if any, that commenced after the Closing Date for which actual results of operations are available, based on the actual Adjusted Operating Surplus of the Partnership generated with respect to such Quarter, and (ii) for each other Quarter, on a pro forma basis consistent with the procedures, as applicable, set forth in Appendix D to the Registration Statement. Furthermore, the amount in clause (A) shall be determined on a pro forma basis assuming that (1) all of the Parity Units to be issued in connection with or within 365

days of such Acquisition or Capital Improvement had been issued and outstanding, (2) all indebtedness for borrowed money to be incurred or assumed in connection with such Acquisition or Capital Improvement (other than any such indebtedness that is to be repaid with the proceeds of such issuance of Parity Units) had been incurred or assumed, in each case as of the commencement of such four-Quarter period, (3) the personnel expenses that would have been incurred by the Partnership in the operation of the acquired assets are the personnel expenses for employees to be retained by the Partnership in the operation of the acquired assets, and (4) the non-personnel costs and expenses are computed on the same basis as those incurred by the Partnership in the operation of the Partnership’s business at similarly situated Partnership facilities. For the purposes of this Section 5.7(b), the term “debt” shall be deemed to include indebtedness used to extend, refinance, renew, replace or defease debt originally incurred in connection with an Acquisition or Capital Improvement; provided, that, the amount of such extended, refinanced, renewed, replaced or defeased indebtedness does not exceed the principal sum of, plus accrued interest on, the indebtedness so extended, replaced renewed, replaced or defeased.

(c) The Partnership may also issue an unlimited number of Parity Units, prior to the end of the Subordination Period and without the approval of the Unitholders, if the proceeds from such issuance are used exclusively to repay indebtedness of a Group Member where the aggregate amount of distributions that would have been paid with respect to such newly issued Units, plus the related distributions on the General Partner Interest in the Partnership in respect of the four-Quarter period ending prior to the first day of the Quarter in which the issuance is to be consummated (assuming such additional Units had been Outstanding throughout such period and that distributions equal to the distributions that were actually paid on the Outstanding Units during the period were paid on such additional Units) would not have exceeded the interest costs actually incurred during such period on the indebtedness that is to be repaid (or, if such indebtedness was not outstanding throughout the entire period, would have been incurred had such indebtedness been outstanding for the entire period). In the event that the Partnership is required to pay a prepayment penalty in connection with the repayment of such indebtedness, for purposes of the foregoing test the number of Parity Units issued to repay such indebtedness shall be deemed increased by the number of Parity Units that would need to be issued to pay such penalty.

(d) During the Subordination Period, without the prior approval of the holders of a Unit Majority, the Partnership shall not issue any additional Partnership Securities (or options, rights, warrants or appreciation rights related thereto) (i) that are entitled in any Quarter to receive in respect of the Subordination Period any distribution of Available Cash from Operating Surplus before the Common Units and any Parity Units have received (or amounts have been set aside for payment of) the Minimum Quarterly Distribution and any Cumulative Common Unit Arrearage for such Quarter or (ii) that are entitled to allocations in respect of the Subordination Period of Net Termination Gain before the Common Units and any Parity Units have been allocated Net Termination Gain pursuant to Section 6.1(c)(i)(B).

(e) During the Subordination Period, without the prior approval of the Unitholders, the Partnership may issue additional Partnership Securities (or options, rights, warrants or appreciation rights related thereto) (i) that are not entitled in any Quarter during the Subordination Period to receive any distributions of Available Cash from Operating Surplus until

after the Common Units and any Parity Units have received (or amounts have been set aside for payment of) the Minimum Quarterly Distribution and any Cumulative Common Unit Arrearage for such Quarter and (ii) that are not entitled to allocations in respect of the Subordination Period of Net Termination Gain before the Common Units and Parity Units have been allocated Net Termination Gain pursuant to Section 6.1(c)(i)(B), even if (A) the amount of Available Cash from Operating Surplus to which each such Partnership Security is entitled to receive after the Minimum Quarterly Distribution and any Cumulative Common Unit Arrearage have been paid or set aside for payment on the Common Units exceeds the Minimum Quarterly Distribution or (B) the amount of Net Termination Gain to be allocated to such Partnership Security after Net Termination Gain has been allocated to any Common Units and Parity Units pursuant to Section 6.1(c)(i)(B) exceeds the amount of such Net Termination Gain to be allocated to each Common Unit or Parity Unit.

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

Section 5.8 Conversion of Senior Subordinated Units.

All of the outstanding Senior Subordinated Units will convert into Common Units on a one-for-one basis on the earlier of (a) February 24, 2006 or (b) the Liquidation Date. A Senior Subordinated Unit that has converted into a Common Unit shall be subject to the provisions of Section 6.7(c).

Section 5.9 Conversion of Senior Subordinated Series B Units.

All of the outstanding Senior Subordinated Series B Units will convert into Common Units on a one-for-one basis on the earlier of (a) November 14, 2005 or (b) the Liquidation Date. A Senior Subordinated Series B Unit that has converted into a Common Unit shall be subject to the provisions of Section 6.8(c).

Section 5.10 Conversion of Senior Subordinated Series C Units.

All of the outstanding Senior Subordinated Series C Units will convert into Common Units on a one-for-one basis on the earlier of (a) February 16, 2008 or (b) the Liquidation Date. A Senior Subordinated Series C Unit that has converted into a Common Unit shall be subject to the provisions of Section 6.9(c).¹


¹		Appropriate provisions shall be made in this Fifth Amended and Restated Agreement of Limited Partnership such that all outstanding Senior Subordinated Series C Units will convert to Common Units on February 16, 2008 only if such conversion is permitted by Section 5.7 hereof. If conversion of the Senior Subordinated Series C Units is not permitted on such date, then such units will have the right to receive, after payment of the Minimum Quarterly Distribution on the Common Units but prior to any payment on the Subordinated Units, distributions equal to 110% of the quarterly cash distribution amount payable on Common Units and appropriate revisions shall be made to this Fifth Amended and Restated Agreement of Limited Partnership. The Senior Subordinated Series C Units will automatically convert to Common Units as soon as such conversion is permitted by Section 5.7 hereof.

Section 5.11 Conversion of Subordinated Units.

(a) A total of 2,333,000 of the Outstanding Subordinated Units will convert into Common Units on a one-for-one basis immediately after the distribution of Available Cash to Partners pursuant to Section 6.3(a) in respect of any Quarter ending on or after December 31, 2005, in respect of which:

(i) distributions under Section 6.4 in respect of all Outstanding Common Units and Subordinated Units and any other Outstanding Units that are senior or equal in right of distribution to the Subordinated Units with respect to each of the three consecutive, non-overlapping four-Quarter periods immediately preceding such date equaled or exceeded the sum of the Minimum Quarterly Distribution on all of the Outstanding Common Units and Subordinated Units and any other Outstanding Units that are senior or equal in right of distribution to the Subordinated Units during such periods;

(ii) the Adjusted Operating Surplus generated during each of the three consecutive, non-overlapping four-Quarter periods immediately preceding such date equaled or exceeded the sum of the Minimum Quarterly Distribution on all of the Common Units, Subordinated Units and any other Units that are senior or equal in right of distribution to the Subordinated Units that were Outstanding during such periods on a Fully Diluted Basis, plus the related distribution on the General Partner Interest in the Partnership, during such periods; and

(iii) the Cumulative Common Unit Arrearage on all of the Common Units is zero.

(b) An additional 2,333,000 of the Outstanding Subordinated Units will convert into Common Units on a one-for-one basis immediately after the distribution of Available Cash to Partners pursuant to Section 6.3(a) in respect of any Quarter ending on or after December 31, 2006, in respect of which:

(iii) the Cumulative Common Unit Arrearage on all of the Common Units is zero;

provided, however, that the conversion of Subordinated Units pursuant to this Section 5.11(b) may not occur until at least one year following the conversion of Subordinated Units pursuant to Section 5.11(a).

(c) In the event that less than all of the Outstanding Subordinated Units shall convert into Common Units pursuant to Sections 5.11(a) or (b) at a time when there shall be more than one holder of Subordinated Units, then, unless all of the holders of Subordinated Units shall agree to a different allocation, the Subordinated Units that are to be converted into Common Units shall be allocated among the holders of Subordinated Units pro rata based on the number of Subordinated Units held by each such holder.

(d) Any Subordinated Units that are not converted into Common Units pursuant to Section 5.11(a) or (b) shall convert into Common Units on a one-for-one basis immediately after the distribution of Available Cash to Partners pursuant to Section 6.3(a) in respect of the final Quarter of the Subordination Period.

(e) Notwithstanding any other provision of this Agreement, all the then Outstanding Subordinated Units will automatically convert into Common Units on a one-for-one basis as set forth in, and pursuant to the terms of, Section 11.4.

(f) A Subordinated Unit that has converted into a Common Unit shall be subject to the provisions of Section 6.10(b).

Section 5.12 Limited Preemptive Right.

Except as provided in this Section 5.12 and in Section 5.2, no Person shall have any preemptive, preferential or other similar right with respect to the issuance of any Partnership Security, whether unissued, held in the treasury or hereafter created. The General Partner shall have the right, which it may from time to time assign in whole or in part to any of its Affiliates, to purchase Partnership Securities from the Partnership whenever, and on the same terms that, the Partnership issues Partnership Securities to Persons other than the General Partner and its Affiliates, to the extent necessary to maintain the Percentage Interests of the General Partner and its Affiliates equal to that which existed immediately prior to the issuance of such Partnership Securities.

Section 5.13 Splits and Combinations.

(a) Subject to Sections 5.13(d), 6.6 and 6.12 (dealing with adjustments of distribution levels), the Partnership may make a Pro Rata distribution of Partnership Securities to all Record Holders or may effect a subdivision or combination of Partnership Securities so long as, after any such event, each Partner shall have the same Percentage Interest in the Partnership as before such event, and any amounts calculated on a per Unit basis (including any Common Unit Arrearage or Cumulative Common Unit Arrearage) or stated as a number of Units (including the number of Subordinated Units that may convert prior to the end of the Subordination Period, the number of Senior Subordinated Units that may convert pursuant to Section 5.8, the number of Senior

Subordinated Series B Units that may convert pursuant to Section 5.9, the number of Senior Subordinated Series C Units that may convert pursuant to Section 5.10 and the number of additional Parity Units that may be issued pursuant to Section 5.7 without a Unitholder vote) are proportionately adjusted retroactive to the beginning of the Partnership.

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

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

(d) The Partnership shall not issue fractional Units upon any distribution, subdivision or combination of Units. If a distribution, subdivision or combination of Units would result in the issuance of fractional Units but for the provisions of Section 5.7(f) and this Section 5.13(d), each fractional Unit shall be rounded to the nearest whole Unit (and a 0.5 Unit shall be rounded to the next higher Unit).

Section 5.14 Fully Paid and Non-Assessable Nature of Limited Partner Interests.

All Limited Partner Interests issued pursuant to, and in accordance with the requirements of, this Article V shall be fully paid and non-assessable Limited Partner Interests in the Partnership, except as such non-assessability may be affected by Section 17-607 of the Delaware Act.

ARTICLE VI

ALLOCATIONS AND DISTRIBUTIONS

Section 6.1 Allocations for Capital Account Purposes.

For purposes of maintaining the balances of Capital Accounts, the Partnership’s items of income, gain, loss and deduction for a taxable period of the Partnership (such items are computed in accordance with Section 5.5(b)) shall be allocated among the Partners first to the extent provided in Section 6.1(d) and then the balance of such items shall be aggregated into Net

Income, Net Loss, Net Termination Gain and Net Termination Loss, as the case may be, which shall then be allocated as follows:

(a) Net Income. Net Income for a taxable period of the Partnership shall be allocated as follows:

(i) First, 100% to the General Partner, until the aggregate Net Income allocated pursuant to this sentence for the current taxable period of the Partnership and all previous taxable periods of the Partnership is equal to the aggregate Net Loss allocated to the General Partner pursuant to Section 6.1(b)(ii) for all previous taxable periods of the Partnership.

(ii) Second, 2% to the General Partner, and 98% to the Unitholders, Pro Rata.

The items of income, gain, loss and deduction that are included in Net Income for a taxable period of the Partnership shall be allocated in the ratio in which Net Income for such taxable period is allocated.

(b) Net Loss. Net Loss for a taxable period of the Partnership shall be allocated as follows:

(i) First, 2% to the General Partner, and 98% to the Unitholders, Pro Rata; provided, that Net Loss shall not be allocated pursuant to this sentence to the extent that such allocation would cause any Unitholder to have a deficit balance in its Adjusted Capital Account at the end of such taxable period of the Partnership (or increase any existing deficit balance in its Adjusted Capital Account). The limitation on the allocation of Net Loss that is contained in the preceding sentence is a Required Allocation for purposes of the allocation of Curative Allocations in Section 6.1(d).

(ii) Second, the balance, if any, 100% to the General Partner.

The items of income, gain, loss and deduction that are included in Net Loss for a taxable period of the Partnership shall be allocated in the ratio in which Net Loss for such taxable period is allocated.

(c) Net Termination Gains and Losses. Allocations under this Section 6.1(c) shall be made after Capital Account balances have been adjusted by all other allocations provided under this Section 6.1 for the current and prior taxable periods of the Partnership and for distributions that have been made pursuant to Sections 6.4 and 6.5 but not for distributions made pursuant to Section 12.4.

(i) Any Net Termination Gain for a taxable period of the Partnership shall be allocated among the Partners in the following manner and the Capital Accounts of the Partners shall be increased by the amount so allocated in each subclause, before an allocation is made pursuant to the next subclause:

(A) First, to each Partner having a deficit balance in its Capital Account, in proportion to such deficit balances until each Partner has been allocated Net Termination Gain equal to any such deficit balance.

(B) Second, 98% to all Unitholders holding Common Units, Pro Rata, and 2% to the General Partner, until the Capital Account in respect of each Common Unit then Outstanding is equal to the sum of (1) its Unrecovered Capital at the time plus (2) the Minimum Quarterly Distribution for the Quarter during which the Liquidation Date occurs, reduced by any distribution pursuant to Section 6.4(a)(i) or (b)(i) with respect to such Common Unit for such Quarter (the amount determined pursuant to this clause (2) is hereinafter defined as the “Unpaid MQD”) plus (3) any then existing Cumulative Common Unit Arrearage.

(C) Third, if such Net Termination Gain is recognized prior to the conversion of the Senior Subordinated Series C Units pursuant to Section 5.10, 98% to all Unitholders holding Senior Subordinated Series C Units, Pro Rata, and 2% to the General Partner, until the Capital Account in respect of each Senior Subordinated Series C Unit then Outstanding equals the sum of (1) the Unrecovered Capital with respect to a Common Unit at the time plus (2) the Unpaid MQD plus (3) any then existing Cumulative Common Unit Arrearage.

(D) Fourth, if such Net Termination Gain is recognized prior to the expiration of the Subordination Period, 98% to all Unitholders holding Subordinated Units, Pro Rata, and 2% to the General Partner, until the Capital Account in respect of each Subordinated Unit then Outstanding equals the sum of (1) its Unrecovered Capital at the time plus (2) the Minimum Quarterly Distribution for the Quarter during which the Liquidation Date occurs, reduced by any distribution pursuant to Section 6.4(a)(iii) with respect to such Subordinated Unit for such Quarter.

(E) Fifth, 85% to all Unitholders, including Senior Subordinated Series C Units, Pro Rata, 13% to the holders of the Incentive Distribution Rights, Pro Rata, and 2% to the General Partner, until the Capital Account in respect of each Common Unit then Outstanding is equal to the sum of (1) its Unrecovered Capital, plus (2) the Unpaid MQD, plus (3) any then existing Cumulative Common Unit Arrearage, plus (4) the excess of (aa) the First Target Distribution less the Minimum Quarterly Distribution for each Quarter of the Partnership’s existence over (bb) the cumulative per Unit amount of any distributions of Available Cash that is deemed to be Operating Surplus made pursuant to Sections 6.4(a)(iv) and 6.4(b)(ii) (the sum of (1) plus (2) plus (3) plus (4) is hereinafter defined as the “First Liquidation Target Amount”).

(F) Sixth, 75% to all Unitholders, including Senior Subordinated Series C Units, Pro Rata, 23% to the holders of the Incentive Distribution Rights, Pro Rata, and 2% to the General Partner, until the Capital Account in respect of each Common Unit then Outstanding is equal to the sum of (1) the First Liquidation Target Amount, plus (2) the excess of (aa) the Second Target

Distribution less the First Target Distribution for each Quarter of the Partnership’s existence over (bb) the cumulative per Unit amount of any distributions of Available Cash that is deemed to be Operating Surplus made pursuant to Sections 6.4(a)(v) and 6.4(b)(iii).

(G) Finally, any remaining amount 50% to all Unitholders, including Senior Subordinated Series C Units, Pro Rata, 48% to the holders of the Incentive Distribution Rights, Pro Rata, and 2% to the General Partner.

(ii) Any Net Termination Loss for a taxable period of the Partnership shall be allocated first as provided in Section 6.1(d)(xi) (with respect to Corrective Allocations) and shall be allocated second among the Partners in the following manner:

(A) First, if such Net Termination Loss is recognized (or is deemed to be recognized) prior to the conversion of the last Outstanding Subordinated Unit, 98% to the Unitholders holding Subordinated Units, Pro Rata, and 2% to the General Partner, until the Capital Account in respect of each Subordinated Unit then Outstanding has been reduced to zero. The limitation on the allocation of Net Termination Loss that is contained in the preceding sentence is a Required Allocation for purposes of the allocation of Curative Allocations in Section 6.1(d).

(B) Second, if such Net Termination Loss is recognized (or is deemed to be recognized) prior to the conversion of the Senior Subordinated Series C Units pursuant to Section 5.10, 98% to all Unitholders holding Senior Subordinated Series C Units, Pro Rata, and 2% to the General Partner, until the Capital Account in respect of each Senior Subordinated Series C Unit then Outstanding has been reduced to zero.

(C) Third, 98% to all Unitholders holding Common Units, Pro Rata, and 2% to the General Partner, until the Capital Account in respect of each Common Unit then Outstanding has been reduced to zero. The limitation on the allocation of Net Termination Loss that is contained in the preceding sentence is a Required Allocation for purposes of the allocation of Curative Allocations in Section 6.1(d).

(D) Fourth, the balance, if any, 100% to the General Partner.

The items of income, gain, loss and deduction that are included in Net Termination Gain or Net Termination Loss for a taxable period of the Partnership shall be allocated in the ratio in which Net Termination Gain or Net Termination Loss for such taxable period is allocated.

(d) Special Allocations. Prior to making any allocation pursuant to another portion of this Section 6.1 for a taxable period of the Partnership, the following allocations shall be made in the order stated:

(i) Partnership Minimum Gain Chargeback. If there is a net decrease in Partnership Minimum Gain during the taxable period of the Partnership, each Partner

shall be allocated items of Partnership income and gain for such taxable period (and, if necessary, subsequent taxable periods of the Partnership) in the manner and amounts provided in Treasury Regulation Sections 1.704-2(f) or any successor provision. This Section 6.1(d)(i) is intended to comply with the Partnership Minimum Gain chargeback requirement in Treasury Regulation Section 1.704-2(f) and shall be interpreted consistently therewith. The allocations in this portion of Section 6.1(d) are a Required Allocation for purposes of the allocation of Curative Allocations in Section 6.1(d).

(ii) Partner Nonrecourse Debt Minimum Gain Chargeback. If there is a net decrease in Partner Nonrecourse Debt Minimum Gain during any taxable period of the Partnership, any Partner with a share of Partner Nonrecourse Debt Minimum Gain at the beginning of such taxable period shall be allocated items of Partnership income and gain for such taxable period (and, if necessary, subsequent taxable periods of the Partnership) in the manner and amounts provided in Treasury Regulation Section 1.704-2(i)(4) or any successor provision. This Section 6.1(d)(ii) is intended to comply with the Partner Nonrecourse Debt Minimum Gain chargeback of items of income and gain requirement in Treasury Regulation Section 1.704-2(i)(4) and shall be interpreted consistently therewith. The allocations in this portion of Section 6.1(d) are a Required Allocation for purposes of the allocation of Curative Allocations in Section 6.1(d).

(iii) Priority Allocations.

(A) First, if the amount of cash or the Net Agreed Value of any property distributed (except cash or property distributed pursuant to Section 12.4) to any class of Unitholders with respect to its Units during any taxable period of the Partnership is greater on a per Unit basis than the amount of cash or the Net Agreed Value of property distributed to any other class of Unitholders (other than the class of Unitholders holding Senior Subordinated Series C Units) with respect to their Units on a per Unit basis in such taxable period, then (1) there shall be allocated items of gross income and gain to each Unitholder receiving such greater distribution until the amount so allocated for the current taxable period and all previous taxable periods pursuant to this clause (1) is equal to (x) the amount by which the distribution on a per Unit basis to such Unitholder exceeds the distribution on a per Unit basis to the Unitholders (other than the class of Unitholders holding Senior Subordinated Series C Units) receiving the smallest distribution multiplied by (y) the number of Units in respect of which such greater distribution was made and (2) the General Partner shall be allocated income and gain in an aggregate amount equal to 2/98ths of the sum of the amounts allocated in clause (1) above. For purposes of applying the provisions of clause (1) (but not clause (2)) of the preceding sentence, (X) each Unitholder acquiring Senior Subordinated Units at original issuance shall be deemed to have received a cash distribution in respect of such Senior Subordinated Units in an amount equal to the product of (a) the total number of Senior Subordinated Units so acquired by such Unitholder, multiplied by (b) the difference between the Initial Unit Price and the Issue Price of the Senior Subordinated Units and (Y) each Unitholder acquiring Senior Subordinated Series B Units at original issuance shall be deemed to have received a cash distribution in respect of such Senior

Subordinated Series B Units in an amount equal to the product of (a) the total number of Senior Subordinated Series B Units so acquired by such Unitholder, multiplied by (b) the difference between the Initial Unit Price and the Issue Price of the Senior Subordinated Series B Units.

(B) Second, income and gain for the taxable period shall be allocated (1) to the General Partner until the aggregate amount so allocated pursuant to this sentence for the current taxable period and all previous taxable periods is equal to the amount that has been distributed to the General Partner Interest that is in excess of 2/98ths of the amount that has been distributed to the holders of Common Units and Subordinated Units and (2) 100% to the holders of Incentive Distribution Rights, Pro Rata, until the aggregate amount so allocated pursuant to this sentence for the current taxable period and all previous taxable periods is equal to the cumulative amount of all Incentive Distributions, in each case, from the Closing Date to a date 45 days after the end of the current taxable period. Any partial distribution pursuant to this Section 6.1(d)(iii)(B) shall be divided between the General Partner and the holders of Incentive Distribution Rights in proportion to their rights to the total distribution that could then be made.

(iv) Qualified Income Offset. In the event any Partner unexpectedly receives any adjustment, allocation or distribution described in Treasury Regulation Sections 1.704-1(b)(2)(ii)(d)(4), (5), or (6), items of income and gain shall be allocated to such Partner in an amount and manner sufficient to eliminate, to the extent required by the Treasury Regulations promulgated under Section 704(b) of the Code, the deficit balance, if any, in its Adjusted Capital Account created by such adjustment, allocation or distribution as quickly as possible. The allocations in this portion of Section 6.1(d) are a Required Allocation for purposes of the allocation of Curative Allocations in Section 6.1(d).

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

(vi) Nonrecourse Deductions. Nonrecourse Deductions for the taxable period shall be allocated to the Partners in accordance with their respective Percentage Interests. If the General Partner determines in good faith that the Partnership’s Nonrecourse Deductions must be allocated in a different ratio to satisfy the safe harbor requirements of the Treasury Regulations promulgated under Section 704(b) of the Code, the General

Partner may, upon notice to the other Partners, revise the prescribed ratio in order to satisfy such safe harbor requirements. The allocations in this portion of Section 6.1(d) are a Required Allocation for purposes of the allocation of Curative Allocations in Section 6.1(d).

(vii) Partner Nonrecourse Deductions. Partner Nonrecourse Deductions for the taxable period shall be allocated 100% to the Partner that bears the Economic Risk of Loss with respect to the Partner Nonrecourse Debt to which such Partner Nonrecourse Deductions are attributable in accordance with Treasury Regulation Section 1.704-2(i). If more than one Partner bears the Economic Risk of Loss with respect to a Partner Nonrecourse Debt, such Partner Nonrecourse Deductions attributable thereto shall be allocated among such Partners in accordance with the manner in which they share such Economic Risk of Loss. The allocations in this portion of Section 6.1(d) are a Required Allocation for purposes of the allocation of Curative Allocations in Section 6.1(d).

(viii) Nonrecourse Liabilities. The portion of the Nonrecourse Liabilities of the Partnership that are allocable pursuant to Treasury Regulation Section 1.752-3(a)(3) shall be allocated among the Partners in accordance with their Percentage Interests. The allocations of Nonrecourse Liabilities that may be made as provided in Treasury Regulation Section 1.752-3(a)(2) are to be made as determined by the General Partner in its sole discretion.

(ix) Economic Uniformity.

(A) At the election of the General Partner with respect to any taxable period of the Partnership ending upon, or after, the termination of the Subordination Period, all or a portion of the remaining items of income and gain for such taxable period shall be allocated 100% to Partners holding Subordinated Units that are Outstanding as of the termination of the Subordination Period (“Final Subordinated Units”) in the proportion of the number of Final Subordinated Units held by such Partners, until each such Partner has been allocated the amount which increases the Capital Account of each Final Subordinated Unit to the Per Unit Capital Amount for a Common Unit.

(B) With respect to any taxable period of the Partnership ending upon, or after, the conversion of all Senior Subordinated Units pursuant to Section 5.8, all or a portion of the remaining items of income and gain for such taxable period shall be allocated 100% to Partners holding Senior Subordinated Units that are Outstanding as of the time of such conversion in the proportion of the number of Senior Subordinated Units held by such Partners, until each such Partner has been allocated the amount which increases the Capital Account of each such Senior Subordinated Unit to the Per Unit Capital Amount for a Common Unit.

(C) With respect to any taxable period of the Partnership ending upon, or after, the conversion of all Senior Subordinated Series B Units pursuant to Section 5.9, all or a portion of the remaining items of income and gain for such taxable period shall be allocated 100% to Partners holding Senior Subordinated

Series B Units that are Outstanding as of the time of such conversion in the proportion of the number of Senior Subordinated Series B Units held by such Partners, until each such Partner has been allocated the amount which increases the Capital Account of each such Senior Subordinated Series B Unit to the Per Unit Capital Amount for a Common Unit.

(D) With respect to any taxable period of the Partnership ending upon, or after, a Book-Up Event or Book-Down Event occurring on or after February 16, 2008, all or a portion of the remaining items of income and gain for such taxable period shall be allocated 100% to Partners holding Senior Subordinated Series C Units or converted Senior Subordinated Series C Units that are Outstanding as of the time of such conversion in the proportion of the number of Senior Subordinated Series C Units or converted Senior Subordinated Series C Units held by such Partners, until each such Partner has been allocated the amount which increases the Capital Account of each such Senior Subordinated Series C Unit or converted Senior Subordinated Series C Unit to the Per Unit Capital Amount for a Common Unit.

(E) With respect to any taxable period of the Partnership ending upon, or after, the transfer of converted Senior Subordinated Series C Units to a Person which is not an Affiliate of the holder, all or a portion of the remaining items of income and gain for such taxable period shall be allocated 100% to the Partners transferring such converted Senior Subordinated Series C Units in the proportion of the number of such converted Senior Subordinated Series C Units transferred by such Partners, until each Partner has been allocated the amount which increases the Capital Account of each such converted Senior Subordinated Series C Unit to the Per Unit Capital Amount for a Common Unit.

(x) Curative Allocation.

(A) Allocations are to be made pursuant to this Section 6.1(d)(x)(A) so that the net amount of items of income, gain, loss and deduction allocated to each Partner pursuant to Section 6.1 (including allocations made pursuant to this Section 6.1(d)(x)) is equal to the net amount of such items that would have been allocated to each such Partner under this Section 6.1 if the Required Allocations had not been included in this Section 6.1; provided that Required Allocations relating to (1) Nonrecourse Deductions shall not be taken into account for purposes of this sentence except to the extent that there has been a decrease in Partnership Minimum Gain and (2) Partner Nonrecourse Deductions shall not be taken into account for purposes of this sentence except to the extent that there has been a decrease in Partner Nonrecourse Debt Minimum Gain and shall then in either case be taken into account only to the extent the General Partner reasonably determines that such allocations are not likely to be offset by subsequent Required Allocations.

(B) The General Partner shall have reasonable discretion, with respect to each taxable period of the Partnership, to (1) apply the provisions of Section

6.1(d)(x)(A) in whatever order is most likely to minimize the economic distortions that might otherwise result from the Required Allocations and (2) divide all allocations pursuant to Section 6.1(d)(x)(A) among the Partners in a manner that is likely to minimize such economic distortions.

(C) For purposes of identifying the Agreed Allocations, the provisions of this Section 6.1(d)(x) are a Required Allocation.

(xi) Corrective Allocations.

(A) Upon the occurrence of a Book-Down Event (the “Current Book-Down Event”) after one or more Book-Up Events has occurred, the General Partner shall determine for each Partner the difference ( the “Net Effect for the Partner”) between

(1) the amount that would be the balance of the Capital Account of such Partner pursuant to this Agreement after the Current Book-Down Event taking into account the provisions of this Agreement other than this Section 6.1(d)(xi)(A) as to the effect of the Current Book–Down Event and

(2) the amount that would be the balance of the Capital Account of the Partner if the increases and decreases in Carrying Values that occurred in earlier Book-Up Events and Book-Down Events had been reduced or eliminated (doing so in inverse order) so that the Current Book-Down Event would not have generated a change in the aggregate Carrying Value of the Partnership’s assets.

Thereafter, the items of income, gain, loss and deduction that the Partnership recognizes (whether in the Current Book-Down Event or otherwise) shall be allocated first among the Partners so that to the greatest extent possible the Net Effect for each Partner is eliminated, and the balance of such items shall then be allocated as otherwise provided in this Section 6.1.

(B) Any Net Termination Loss that is recognized and so characterized without regard to this Section 6.1(d)(xi)(B), shall be allocated among the Partners so as to reverse first the allocations of any Net Termination Gain that was recognized in a prior taxable period to the extent thereof and to reverse second the effect of any Book-Up Event that has not theretofore been eliminated pursuant to Section 6.1(d)(xi)(A). Any balance of the Net Termination Loss shall then be allocated as provided in Section 6.1(c)(ii).

(C) The purpose of this Section 6.1(d)(xi) is to prevent a Partner from being adversely affected by the occurrence of a Book-Up Event and its later reversal by a Book-Down Event or by a Net Termination Gain and its later reversal by a Net Termination Loss. Any application of this Section 6.1(d)(xi) that is made in good faith by the General Partner shall be conclusive.

(xii) Allocation to Reverse Deemed Capital Contributions. Any items of loss or deduction resulting from or relating to the grant of options to acquire stock, or the issuance of stock, by Crosstex Energy, Inc., or from the transfer of any other property by the General Partner, Crosstex GP, or Crosstex Energy, Inc., to any employee or other service provider of the Partnership, the Operating Partnership, or any of their respective Subsidiaries shall be specially allocated to the General Partner if and to the extent such grant of options, issuance of stock, or transfer of property was treated under applicable tax law as a deemed capital contribution by the General Partner which resulted in an increase to the General Partner’s Capital Account.

The items of income, gain, loss and deduction that are included in an aggregate that is allocated pursuant to a provision of this Section 6.1(d) for a taxable period of the Partnership shall be allocated in the ratio that such aggregate was allocated.

Section 6.2 Allocations for Tax Purposes.

(a) Except as otherwise provided in this Section 6.2, each item of income, gain, loss and deduction that is recognized by the Partnership for federal income tax purposes shall be allocated among the Partners with reference to the allocations of the corresponding items pursuant to Section 6.1.

(b) The Partnership shall make the allocations that are required by Section 704(c) of the Code with respect to the difference between the fair market value and adjusted basis for federal income tax purposes of any asset that the Partnership holds on the Closing Date using remedial allocations within the meaning of Treasury Regulation Section 1.704-3(d) and in respect of the difference between fair market value and adjusted tax basis of such assets the Partnership shall use the recovery periods and depreciation methods that are used in the calculations that are identified in the records of the Partnership as the basis of the estimates that are reported in the “Material Tax Consequences-Tax Consequences of Unit Ownership – Ratio of taxable income to distributions” section of the prospectus that is part of the Registration Statement except as may be provided in the Contribution Agreements. The Partnership shall, at any other time that it acquires property with respect to which it must make allocations for federal income tax purposes pursuant to Section 704(c) of the Code, make such allocations using remedial allocations within the meaning of Treasury Regulation Section 1.704-3(d) or any other method selected by the General Partner in its sole discretion. The Partnership shall make any “reverse section 704(c) allocations”, within the meaning of Treasury Regulation Section 1.704-3(a)(6), that may be made upon an adjustment in Carrying Values pursuant to Section 5.5(d) or at any other time that the General Partner determines in its sole discretion that the Partnership should make “reverse section 704(c) allocations” as “remedial allocations” as set out in Treasury Regulation Section 1.704-3(d) or under any other method that the General Partner determines in its sole discretion that the Partnership should use. The General Partner may cause the Partnership to make agreements as to the manner in which Section 704(c) allocations shall be made upon the acquisition by the Partnership of property in exchange for a Partnership Interest or reverse Section 704(c) allocations shall be made with respect to the assets of the Partnership upon the issuance by the Partnership of a Partnership Interest.

(c) For the proper administration of the Partnership and to facilitate the calculation of the items of income, gain, loss and deduction that are allocated to the Partners for federal, state or local income tax purposes and to take into account the effect of the Section 754 election that the Partnership is to make, the General Partner shall have sole discretion (i) to adopt such conventions as it deems appropriate in determining the amount of depreciation, amortization and cost recovery deductions; (ii) to make special allocations for federal income tax purposes of income (including, without limitation, gross income) or deductions; and (iii) to amend the provisions of this Agreement as appropriate (x) to reflect the proposal or promulgation of Treasury Regulations under Section 704(b) or Section 704(c) of the Code or (y) otherwise to preserve or achieve uniformity of the Limited Partner Interests (or any class or classes thereof) or to facilitate the calculation of such adjustments that are required by the Section 754 election from the information that is known by the Partnership, such as the date of the purchase of a Limited Partner Interest and the amount that is paid therefor.

(d) The General Partner in its discretion may determine to depreciate or amortize the portion of an adjustment under Section 743(b) of the Code that is attributable to unrealized appreciation in any Partnership property (to the extent of the unamortized difference between Carrying Value and adjusted basis for federal income tax purposes or if more than one adjustment to Carrying Value has been made to the extent of any unamortized increment between Carrying Value and the immediately prior Carrying Value) using a predetermined rate derived from the depreciation or amortization method and useful life applied to the Partnership’s common basis of such property. If the General Partner determines that such reporting position cannot reasonably be taken, the General Partner may adopt depreciation and amortization conventions under which all purchasers acquiring Limited Partner Interests in the same month would receive depreciation and amortization deductions, based upon the same applicable rate as if they had purchased a direct interest in the Partnership’s property. If the General Partner chooses not to utilize such aggregate method, the General Partner may use any other depreciation and amortization conventions that it determines are appropriate.

(e) Any gain allocated to a Partner upon the sale or other taxable disposition of any Partnership asset shall, to the extent possible be characterized as Recapture Income to the same extent as such Partner (or its predecessor in interest) has been allocated any deductions directly or indirectly giving rise to the treatment of such gains as Recapture Income.

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

(g) Each item of Partnership income, gain, loss and deduction that is allocated to a Partner Interest that is transferred during a calendar year shall for federal income tax purposes, be determined on an annual basis and prorated on a monthly basis and shall be allocated to the Partners as of the opening of the New York Stock Exchange on the first Business Day of each month; provided, however, that (i) such items for the period beginning on the Closing Date and ending on the last day of the month in which the expiration of the Over-Allotment Option occurs

shall be allocated to the Partners as of the opening of the New York Stock Exchange on the first Business Day of the next succeeding month; and provided, further, that gain or loss on a sale or other disposition of any assets of the Partnership or any other extraordinary item of income or loss realized and recognized other than in the ordinary course of business, as determined by the General Partner in its sole discretion, shall be allocated to the Partners as of the opening of the New York Stock Exchange on the first Business Day of the month in which such gain or loss is recognized for federal income tax purposes. The General Partner may revise, alter or otherwise modify such methods of allocation as it determines necessary or appropriate in its sole discretion, to the extent permitted or required by Section 706 of the Code and the regulations or rulings promulgated thereunder.

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

(a) Within 45 days following the end of each Quarter commencing with the Quarter ending on March 31, 2003, an amount equal to 100% of Available Cash with respect to such Quarter shall, subject to Section 17-607 of the Delaware Act, be distributed in accordance with this Article VI by the Partnership to the Partners as of the Record Date selected by the General Partner in its reasonable discretion. All amounts of Available Cash distributed by the Partnership on any date from any source shall be deemed to be Operating Surplus until the sum of all amounts of Available Cash theretofore distributed by the Partnership to the Partners pursuant to Section 6.4 equals the Operating Surplus from the Closing Date through the close of the immediately preceding Quarter. Any remaining amounts of Available Cash distributed by the Partnership on such date shall, except as otherwise provided in Section 6.5, be deemed to be “Capital Surplus.” All distributions required to be made under this Agreement shall be made subject to Section 17-607 of the Delaware Act.

(b) Notwithstanding Section 6.3(a), in the event of the dissolution and liquidation of the Partnership, all receipts received during or after the Quarter in which the Liquidation Date occurs, other than from borrowings described in (a)(ii) of the definition of Available Cash, shall be applied and distributed solely in accordance with, and subject to the terms and conditions of, Section 12.4.

(c) The General Partner shall have the discretion to treat taxes paid by the Partnership on behalf of, or amounts withheld with respect to, all or less than all of the Partners, as a distribution of Available Cash to such Partners.

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

Section 6.4 Distributions of Available Cash from Operating Surplus.

(a) During Subordination Period. Available Cash with respect to any Quarter within the Subordination Period that is deemed to be Operating Surplus pursuant to the provisions of Section 6.3 or 6.5 shall, subject to Section 17-607 of the Delaware Act, be distributed as follows, except as otherwise required by Section 5.6(b) in respect of additional Partnership Securities issued pursuant thereto:

(i) First, 98% to the Unitholders holding Common Units, Pro Rata, and 2% to the General Partner, until there has been distributed in respect of each Common Unit then Outstanding an amount equal to the Minimum Quarterly Distribution for such Quarter;

(ii) Second, 98% to the Unitholders holding Common Units, Pro Rata, and 2% to the General Partner, until there has been distributed in respect of each Common Unit then Outstanding an amount equal to the Cumulative Common Unit Arrearage existing with respect to such Quarter;

(iii) Third, 98% to the Unitholders holding Subordinated Units, Pro Rata, and 2% to the General Partner, until there has been distributed in respect of each Subordinated Unit then Outstanding an amount equal to the Minimum Quarterly Distribution for such Quarter;

(iv) Fourth, 85% to the Unitholders holding Common Units and Subordinated Units, Pro Rata, 13% to the holders of the Incentive Distribution Rights, Pro Rata, and 2% to the General Partner, until there has been distributed in respect of each Unit then Outstanding an amount equal to the excess of the First Target Distribution over the Minimum Quarterly Distribution for such Quarter;

(v) Fifth, 75% to the Unitholders holding Common Units and Subordinated Units, Pro Rata, 23% to the holders of the Incentive Distribution Rights, Pro Rata, and 2% to the General Partner, until there has been distributed in respect of each Unit then Outstanding an amount equal to the excess of the Second Target Distribution over the First Target Distribution for such Quarter; and

(vi) Thereafter, 50% to the Unitholders holding Common Units and Subordinated Units, Pro Rata, 48% to the holders of the Incentive Distribution Rights, Pro Rata, and 2% to the General Partner;

provided, however, if the Minimum Quarterly Distribution, the First Target Distribution and the Second Target Distribution have been reduced to zero pursuant to the second sentence of Section 6.6(a), the distribution of Available Cash that is deemed to be Operating Surplus with respect to any Quarter will be made solely in accordance with Section 6.4(a)(vi).

(b) After Subordination Period. Available Cash with respect to any Quarter after the Subordination Period that is deemed to be Operating Surplus pursuant to the provisions of Section 6.3 or 6.5 shall, subject to Section 17-607 of the Delaware Act, be distributed as follows, except as otherwise required by Section 5.6(b) in respect of additional Partnership Securities issued pursuant thereto:

(i) First, 98% to all Unitholders, Pro Rata, and 2% to the General Partner, until there has been distributed in respect of each Unit then Outstanding an amount equal to the Minimum Quarterly Distribution for such Quarter;

(ii) Second, 85% to all Unitholders, Pro Rata, 13% to the holders of the Incentive Distribution Rights, Pro Rata, and 2% to the General Partner, until there has been distributed in respect of each Unit then Outstanding an amount equal to the excess of the First Target Distribution over the Minimum Quarterly Distribution for such Quarter;

(iii) Third, 75% to all Unitholders, Pro Rata, 23% to the holders of the Incentive Distribution Rights, Pro Rata, and 2% to the General Partner, until there has been distributed in respect of each Unit then Outstanding an amount equal to the excess of the Second Target Distribution over the First Target Distribution for such Quarter; and

(iv) Thereafter, 50% to all Unitholders, Pro Rata, 48% to the holders of the Incentive Distribution Rights, Pro Rata, and 2% to the General Partner;

Section 6.5 Distributions of Available Cash from Capital Surplus.

Available Cash that is deemed to be Capital Surplus pursuant to the provisions of Section 6.3(a) shall, subject to Section 17-607 of the Delaware Act, be distributed, unless the provisions of Section 6.3 require otherwise, 98% to all Unitholders, Pro Rata, and 2% to the General Partner, until a hypothetical holder of an Initial Common Unit acquired on the Closing Date has received with respect to such Common Unit, during the period since the Closing Date through such date, distributions of Available Cash that are deemed to be Capital Surplus in an aggregate amount equal to the Initial Unit Price. Available Cash that is deemed to be Capital Surplus shall then be distributed 98% to all Unitholders holding Common Units, Pro Rata, and 2% to the General Partner, until there has been distributed in respect of each Common Unit then Outstanding an amount equal to the Cumulative Common Unit Arrearage. Thereafter, all Available Cash shall be distributed as if it were Operating Surplus and shall be distributed in accordance with Section 6.4. For purposes of applying this Section 6.5, each Senior Subordinated Unit, each Senior Subordinated Series B Unit and each Senior Subordinated Series C Unit then Outstanding shall be treated as if it had converted into a Common Unit.

Section 6.6 Adjustment of Minimum Quarterly Distribution and Target Distribution Levels.

(a) The Minimum Quarterly Distribution, First Target Distribution, Second Target Distribution, Common Unit Arrearages and Cumulative Common Unit Arrearages shall be proportionately adjusted in the event of any distribution, combination or subdivision (whether effected by a distribution payable in Units or otherwise) of Units or other Partnership Securities in accordance with Section 5.12. In the event of a distribution of Available Cash that is deemed

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

(b) The Minimum Quarterly Distribution, First Target Distribution and Second Target Distribution shall also be subject to adjustment pursuant to Section 6.11.

Section 6.7 Special Provisions Relating to the Holders of Senior Subordinated Units.

(a) Except as provided in Section 6.5, until the conversion of the Senior Subordinated Units into Common Units pursuant to Section 5.8, the Unitholders holding Senior Subordinated Units shall have no right to the distribution of Available Cash pursuant to this Article VI.

(b) Except with respect to the right to receive distributions of Available Cash, the right to vote on or approve matters requiring the vote or approval of a percentage of the holders of Outstanding Common Units and the right to participate in allocations of income, gain, loss and deduction and distributions made with respect to Common Units, the holder of a Senior Subordinated Unit shall have all of the rights and obligations of a Unitholder holding Common Units hereunder; provided, however, that immediately upon the conversion of Senior Subordinated Units into Common Units pursuant to Section 5.8, the Unitholder holding a Senior Subordinated Unit shall possess all of the rights and obligations of a Unitholder holding Common Units hereunder, including the right to receive distributions of Available Cash, the right to vote as a Common Unitholder and the right to participate in allocations of income, gain, loss and deduction and distributions made with respect to Common Units; provided, however, that such converted Senior Subordinated Units shall remain subject to the provisions of Sections 5.5(c)(ii), 6.1(d)(ix) and 6.7(c).

(c) A Unitholder holding a Senior Subordinated Unit which has converted into a Common Unit pursuant to Section 5.8 shall not be issued a Common Unit Certificate pursuant to Section 4.1, and shall not be permitted to transfer its converted Senior Subordinated Units to a Person which is not an Affiliate of the holder until such time as the General Partner determines, based on advice of counsel, that a converted Senior Subordinated Unit should have, as a substantive matter, like intrinsic economic and federal income tax characteristics, in all material respects, to the intrinsic economic and federal income tax characteristics of an Initial Common Unit; provided, however, that the comparison of such federal income tax characteristics shall be made by comparing the federal income tax characteristics of an Initial Common Unit and the converted Senior Subordinated Unit in the hands of a purchaser for cash of such converted Senior Subordinated Unit for its fair market value.

Section 6.12 Entity-Level Taxation.

If legislation is enacted or the interpretation of existing language is modified by the relevant governmental authority which causes a Group Member to be treated as an association taxable as a corporation or otherwise subjects a Group Member to entity-level taxation for federal, state or local income tax purposes, the then applicable Minimum Quarterly Distribution, First Target Distribution and Second Target Distribution shall be adjusted to equal the product obtained by multiplying (a) the amount thereof by (b) one minus the sum of (i) the highest marginal federal corporate (or other entity, as applicable) income tax rate of the Group Member for the taxable year of the Group Member in which such Quarter occurs (expressed as a percentage) plus (ii) the effective overall state and local income tax rate (expressed as a

percentage) applicable to the Group Member for the calendar year next preceding the calendar year in which such Quarter occurs (after taking into account the benefit of any deduction allowable for federal income tax purposes with respect to the payment of state and local income taxes), but only to the extent of the increase in such rates resulting from such legislation or interpretation. Such effective overall state and local income tax rate shall be determined for the taxable year next preceding the first taxable year during which the Group Member is taxable for federal income tax purposes as an association taxable as a corporation or is otherwise subject to entity-level taxation by determining such rate as if the Group Member had been subject to such state and local taxes during such preceding taxable year.

To the extent that such action is determined by the General Partner in its sole discretion to be reasonable and necessary or appropriate, the General Partner shall file amendments to and restatements of the Certificate of Limited Partnership and do all things to maintain the Partnership as a limited partnership (or a partnership or other entity in which the limited partners have limited liability) under the laws of the State of Delaware or of any other state in which the Partnership may elect to do business or own property. Subject to the terms of Section 3.4(a), the General Partner shall not be required, before or after filing, to deliver or mail a copy of the Certificate of Limited Partnership, any qualification document or any amendment thereto to any Limited Partner.

Without the approval of holders of a Unit Majority, the General Partner shall not, on behalf of the Partnership, (i)(A) consent to any amendment to the Operating Partnership Agreement, (B) except as expressly permitted by Section 7.9(d), take any action permitted to be taken by a partner of the Operating Partnership, or (C) cause the reduction of the interest of the Partnership in preferred units of the Operating Partnership, or in other equity, debt or other securities of the Operating Partnership, that are or may hereafter be held by Crosstex Louisiana Energy, L.P., a Delaware limited partnership, or its Subsidiaries or fail to prevent such a reduction (including any reduction which would occur by reason of a sale or other disposition of any such security of the Operating Partnership or by reason of an issuance or a sale or other disposition of any security of Crosstex Louisiana Energy, L.P. or any Subsidiary thereof), provided, however, that this clause (C) shall not preclude or limit the General Partner’s ability to mortgage, pledge, hypothecate or grant a security interest in all or substantially all of the assets of the Partnership or the Operating Partnership or their Subsidiaries and shall not apply to any forced sale of any or all of the assets of the Partnership or the Operating Partnership or their Subsidiaries pursuant to the foreclosure of, or other realization upon, any such encumbrance, in the case of clauses (A) through (C), that would adversely affect the Limited Partners (including any particular class of Partnership Interests as compared to any other class of Partnership Interests) in any material respect or (ii) except as permitted under Sections 4.6, 11.1 and 11.2, elect or cause the Partnership to elect a successor general partner of the Partnership.

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

(b) The General Partner shall be reimbursed on a monthly basis, or such other reasonable basis as the General Partner may determine in its sole discretion, for (i) all direct and indirect expenses it incurs or payments it makes on behalf of the Partnership (including salary, bonus, incentive compensation and other amounts paid to any Person including Affiliates of the General Partner to perform services for the Partnership or for the General Partner in the discharge of its duties to the Partnership), and (ii) all other necessary or appropriate expenses allocable to the Partnership or otherwise reasonably incurred by the General Partner in

connection with operating the Partnership’s business (including expenses allocated to the General Partner by its Affiliates). The General Partner shall determine the expenses that are allocable to the Partnership in any reasonable manner determined by the General Partner in its sole discretion. Reimbursements pursuant to this Section 7.4 shall be in addition to any reimbursement to the General Partner as a result of indemnification pursuant to Section 7.7.

(c) Subject to Section 5.7, the General Partner, in its sole discretion and without the approval of the Limited Partners (who shall have no right to vote in respect thereof), may propose and adopt on behalf of the Partnership employee benefit plans, employee programs and employee practices (including plans, programs and practices involving the issuance of Partnership Securities or options to purchase or rights, warrants or appreciation rights relating to Partnership Securities), or cause the Partnership to issue Partnership Securities in connection with, or pursuant to, any employee benefit plan, employee program or employee practice maintained or sponsored by the General Partner or any of its Affiliates, in each case for the benefit of employees of the General Partner, any Group Member or any Affiliate, or any of them, in respect of services performed, directly or indirectly, for the benefit of the Partnership Group. The Partnership agrees to issue and sell to the General Partner or any of its Affiliates any Partnership Securities that the General Partner or such Affiliates are obligated to provide to any employees pursuant to any such employee benefit plans, employee programs or employee practices. Expenses incurred by the General Partner in connection with any such plans, programs and practices (including the net cost to the General Partner or such Affiliates of Partnership Securities purchased by the General Partner or such Affiliates from the Partnership to fulfill options or awards under such plans, programs and practices) shall be reimbursed in accordance with Section 7.4(b). Any and all obligations of the General Partner under any employee benefit plans, employee programs or employee practices adopted by the General Partner as permitted by this Section 7.4(c) shall constitute obligations of the General Partner hereunder and shall be assumed by any successor General Partner approved pursuant to Section 11.1 or 11.2 or the transferee of or successor to all of the General Partner’s General Partner Interest pursuant to Section 4.6.

Section 7.5 Outside Activities.

(a) After the Closing Date, the General Partner, for so long as it is the General Partner of the Partnership (i) agrees that its sole business will be to act as a general partner or managing member, as the case may be, of the Partnership and any other partnership or limited liability company of which the Partnership or the Operating Partnership is, directly or indirectly, a partner or member and to undertake activities that are ancillary or related thereto (including being a limited partner in the Partnership), (ii) shall not engage in any business or activity or incur any debts or liabilities except in connection with or incidental to (A) its performance as general partner or managing member of one or more Group Members or as described in or contemplated by the Registration Statement or (B) the acquiring, owning or disposing of debt or equity securities in any Group Member and (iii) except to the extent permitted in the Omnibus Agreement, shall not, and shall cause its Affiliates not to, engage in any Restricted Business.

(b) Crosstex Energy, Inc. and certain of its Affiliates have entered into the Omnibus Agreement, which agreement sets forth certain restrictions on the ability of Crosstex Energy, Inc. and its Affiliates to engage in Restricted Businesses.

(c) Except as specifically restricted by Section 7.5(a) and the Omnibus Agreement, each Indemnitee (other than the General Partner) shall have the right to engage in businesses of every type and description and other activities for profit and to engage in and possess an interest in other business ventures of any and every type or description, whether in businesses engaged in or anticipated to be engaged in by any Group Member, independently or with others, including business interests and activities in direct competition with the business and activities of any Group Member, and none of the same shall constitute a breach of this Agreement or any duty express or implied by law to any Group Member or any Partner or Assignee. Neither any Group Member, any Limited Partner nor any other Person shall have any rights by virtue of this Agreement, the Operating Partnership Agreement, the limited liability company or partnership agreements of any other Group Member or the partnership relationship established hereby in any business ventures of any Indemnitee.

(d) Subject to the terms of Section 7.5(a), Section 7.5(b), Section 7.5(c) and the Omnibus Agreement, but otherwise notwithstanding anything to the contrary in this Agreement, (i) the engaging in competitive activities by any Indemnitees (other than the General Partner) in accordance with the provisions of this Section 7.5 is hereby approved by the Partnership and all Partners, (ii) it shall be deemed not to be a breach of the General Partner’s fiduciary duty or any other obligation of any type whatsoever of the General Partner for the Indemnitees (other than the General Partner) to engage in such business interests and activities in preference to or to the exclusion of the Partnership and (iii) except as set forth in the Omnibus Agreement, the General Partner and the Indemnitees shall have no obligation to present business opportunities to the Partnership.

(e) The General Partner and any of its Affiliates may acquire Units or other Partnership Securities in addition to those acquired on the Closing Date and, except as otherwise provided in this Agreement, shall be entitled to exercise all rights of the General Partner or Limited Partner, as applicable, relating to such Units or Partnership Securities.

(f) The term “Affiliates” when used in Section 7.5(a) and Section 7.5(e) with respect to the General Partner shall not include any Group Member or any Subsidiary of the Group Member.

(g) Anything in this Agreement to the contrary notwithstanding, to the extent that provisions of Sections 7.7, 7.8, 7.9, 7.10 or other Sections of this Agreement purport or are interpreted to have the effect of restricting the fiduciary duties that might otherwise, as a result of Delaware or other applicable law, be owed by the General Partner to the Partnership and its Limited Partners, or to constitute a waiver or consent by the Limited Partners to any such restriction, such provisions shall be inapplicable and have no effect in determining whether the General Partner has complied with its fiduciary duties in connection with determinations made by it under this Section 7.5.

Section 7.6 Loans from the General Partner; Loans or Contributions from the Partnership; Contracts with Affiliates; Certain Restrictions on the General Partner.

(a) The General Partner or any of its Affiliates may lend to any Group Member, and any Group Member may borrow from the General Partner or any of its Affiliates, funds needed or desired by the Group Member for such periods of time and in such amounts as the General Partner may determine; provided, however, that in any such case the lending party may not charge the borrowing party interest at a rate greater than the rate that would be charged the borrowing party or impose terms less favorable to the borrowing party than would be charged or imposed on the borrowing party by unrelated lenders on comparable loans made on an arm’s-length basis (without reference to the lending party’s financial abilities or guarantees). The borrowing party shall reimburse the lending party for any costs (other than any additional interest costs) incurred by the lending party in connection with the borrowing of such funds. For purposes of this Section 7.6(a) and Section 7.6(b), the term “Group Member” shall include any Affiliate of a Group Member that is controlled by the Group Member. No Group Member may lend funds to the General Partner or any of its Affiliates (other than another Group Member).

(b) The Partnership may lend or contribute to any Group Member, and any Group Member may borrow from the Partnership, funds on terms and conditions established in the sole discretion of the General Partner; provided, however, that the Partnership may not charge the Group Member interest at a rate less than the rate that would be charged to the Group Member (without reference to the General Partner’s financial abilities or guarantees) by unrelated lenders on comparable loans. The foregoing authority shall be exercised by the General Partner in its sole discretion and shall not create any right or benefit in favor of any Group Member or any other Person.

(c) The General Partner may itself, or may enter into an agreement with any of its Affiliates to, render services to a Group Member or to the General Partner in the discharge of its duties as General Partner of the Partnership. Any services rendered to a Group Member by the General Partner or any of its Affiliates shall be on terms that are fair and reasonable to the Partnership; provided, however, that the requirements of this Section 7.6(c) shall be deemed satisfied as to (i) any transaction approved by Special Approval, (ii) any transaction, the terms of which are no less favorable to the Partnership Group than those generally being provided to or available from unrelated third parties or (iii) any transaction that, taking into account the totality of the relationships between the parties involved (including other transactions that may be particularly favorable or advantageous to the Partnership Group), is equitable to the Partnership Group. The provisions of Section 7.4 shall apply to the rendering of services described in this Section 7.6(c).

(d) The Partnership Group may transfer assets to joint ventures, other partnerships, corporations, limited liability companies or other business entities in which it is or thereby becomes a participant upon such terms and subject to such conditions as are consistent with this Agreement and applicable law.

(e) Neither the General Partner nor any of its Affiliates shall sell, transfer or convey any property to, or purchase any property from, the Partnership, directly or indirectly, except

pursuant to transactions that are fair and reasonable to the Partnership; provided, however, that the requirements of this Section 7.6(e) shall be deemed to be satisfied as to (i) the transactions effected pursuant to Sections 5.2 and 5.3, the Contribution Agreements and any other transactions described in or contemplated by the Registration Statement, (ii) any transaction approved by Special Approval, (iii) any transaction, the terms of which are no less favorable to the Partnership than those generally being provided to or available from unrelated third parties, or (iv) any transaction that, taking into account the totality of the relationships between the parties involved (including other transactions that may be particularly favorable or advantageous to the Partnership), is equitable to the Partnership. With respect to any contribution of assets to the Partnership in exchange for Partnership Securities, the Conflicts Committee, in determining whether the appropriate number of Partnership Securities are being issued, may take into account, among other things, the fair market value of the assets, the liquidated and contingent liabilities assumed, the tax basis in the assets, the extent to which tax-only allocations to the transferor will protect the existing partners of the Partnership against a low tax basis, and such other factors as the Conflicts Committee deems relevant under the circumstances.

(f) The General Partner and its Affiliates will have no obligation to permit any Group Member to use any facilities or assets of the General Partner and its Affiliates, except as may be provided in contracts entered into from time to time specifically dealing with such use, nor shall there be any obligation on the part of the General Partner or its Affiliates to enter into such contracts.

(g) Without limitation of Sections 7.6(a) through 7.6(f), and notwithstanding anything to the contrary in this Agreement, the existence of the conflicts of interest described in the Registration Statement are hereby approved by all Partners.

Section 7.7 Indemnification.

(a) To the fullest extent permitted by law but subject to the limitations expressly provided in this Agreement, all Indemnitees shall be indemnified and held harmless by the Partnership from and against any and all losses, claims, damages, liabilities, joint or several, expenses (including legal fees and expenses), judgments, fines, penalties, interest, settlements or other amounts arising from any and all claims, demands, actions, suits or proceedings, whether civil, criminal, administrative or investigative, in which any Indemnitee may be involved, or is threatened to be involved, as a party or otherwise, by reason of its status as an Indemnitee; provided, that in each case the Indemnitee acted in good faith and in a manner that such Indemnitee reasonably believed to be in, or (in the case of a Person other than the General Partner) not opposed to, the best interests of the Partnership and, with respect to any criminal proceeding, had no reasonable cause to believe its conduct was unlawful; provided, further, no indemnification pursuant to this Section 7.7 shall be available to the General Partner or its Affiliates (other than a Group Member) with respect to its or their obligations incurred pursuant to the Underwriting Agreement or the Contribution Agreements (other than obligations incurred by the General Partner on behalf of the Partnership). The termination of any action, suit or proceeding by judgment, order, settlement, conviction or upon a plea of nolo contendere, or its equivalent, shall not create a presumption that the Indemnitee acted in a manner contrary to that specified above. Any indemnification pursuant to this Section 7.7 shall be made only out of the assets of the Partnership, it being agreed that the General Partner shall not be personally liable

for such indemnification and shall have no obligation to contribute or loan any monies or property to the Partnership to enable it to effectuate such indemnification.

(b) To the fullest extent permitted by law, expenses (including legal fees and expenses) incurred by an Indemnitee who is indemnified pursuant to Section 7.7(a) in defending any claim, demand, action, suit or proceeding shall, from time to time, be advanced by the Partnership prior to the final disposition of such claim, demand, action, suit or proceeding upon receipt by the Partnership of any undertaking by or on behalf of the Indemnitee to repay such amount if it shall be determined that the Indemnitee is not entitled to be indemnified as authorized in this Section 7.7.

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

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

(e) For purposes of this Section 7.7, the Partnership shall be deemed to have requested an Indemnitee to serve as fiduciary of an employee benefit plan whenever the performance by it of its duties to the Partnership also imposes duties on, or otherwise involves services by, it to the plan or participants or beneficiaries of the plan; excise taxes assessed on an Indemnitee with respect to an employee benefit plan pursuant to applicable law shall constitute “fines” within the meaning of Section 7.7(a); and action taken or omitted by it with respect to any employee benefit plan in the performance of its duties for a purpose reasonably believed by it to be in the interest of the participants and beneficiaries of the plan shall be deemed to be for a purpose which is in, or not opposed to, the best interests of the Partnership.

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

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

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

(i) No amendment, modification or repeal of this Section 7.7 or any provision hereof shall in any manner terminate, reduce or impair the right of any past, present or future Indemnitee to be indemnified by the Partnership, nor the obligations of the Partnership to indemnify any such Indemnitee under and in accordance with the provisions of this Section 7.7 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted.

Section 7.8 Liability of Indemnitees.

(a) Notwithstanding anything to the contrary set forth in this Agreement, no Indemnitee shall be liable for monetary damages to the Partnership, the Limited Partners, the Assignees or any other Persons who have acquired interests in the Partnership Securities, for losses sustained or liabilities incurred as a result of any act or omission if such Indemnitee acted in good faith.

(b) Subject to its obligations and duties as General Partner set forth in Section 7.1(a), the General Partner may exercise any of the powers granted to it by this Agreement and perform any of the duties imposed upon it hereunder either directly or by or through its agents, and the General Partner shall not be responsible for any misconduct or negligence on the part of any such agent appointed by the General Partner in good faith.

(c) To the extent that, at law or in equity, an Indemnitee has duties (including fiduciary duties) and liabilities relating thereto to the Partnership or to the Partners, the General Partner and any other Indemnitee acting in connection with the Partnership’s business or affairs shall not be liable to the Partnership or to any Partner for its good faith reliance on the provisions of this Agreement. The provisions of this Agreement, to the extent that they restrict or otherwise modify the duties and liabilities of an Indemnitee otherwise existing at law or in equity, are agreed by the Partners to replace such other duties and liabilities of such Indemnitee.

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

Section 7.9 Resolution of Conflicts of Interest.

(a) Unless otherwise expressly provided in this Agreement, the Operating Partnership Agreement or the limited liability company or partnership agreement of any other Group Member, whenever a potential conflict of interest exists or arises between the General Partner or any of its Affiliates, on the one hand, and the Partnership, the Operating Partnership, any other

Group Member, any Partner or any Assignee, on the other, any resolution or course of action by the General Partner or its Affiliates in respect of such conflict of interest shall be permitted and deemed approved by all Partners, and shall not constitute a breach of this Agreement, of the Operating Partnership Agreement, of any agreement contemplated herein or therein, or of any duty stated or implied by law or equity, if the resolution or course of action is, or by operation of this Agreement is deemed to be, fair and reasonable to the Partnership. The General Partner shall be authorized but not required in connection with its resolution of such conflict of interest to seek Special Approval of such resolution. Any conflict of interest and any resolution of such conflict of interest shall be conclusively deemed fair and reasonable to the Partnership if such conflict of interest or resolution is (i) approved by Special Approval (as long as the material facts known to the General Partner or any of its Affiliates regarding any proposed transaction were disclosed to the Conflicts Committee at the time it gave its approval), (ii) on terms no less favorable to the Partnership than those generally being provided to or available from unrelated third parties or (iii) fair to the Partnership, taking into account the totality of the relationships between the parties involved (including other transactions that may be particularly favorable or advantageous to the Partnership). The General Partner may also adopt a resolution or course of action that has not received Special Approval. The General Partner (including the Conflicts Committee in connection with Special Approval) shall be authorized in connection with its determination of what is “fair and reasonable” to the Partnership and in connection with its resolution of any conflict of interest to consider (A) the relative interests of any party to such conflict, agreement, transaction or situation and the benefits and burdens relating to such interest; (B) any customary or accepted industry practices and any customary or historical dealings with a particular Person; (C) any applicable generally accepted accounting practices or principles; and (D) such additional factors as the General Partner (including the Conflicts Committee) determines in its sole discretion to be relevant, reasonable or appropriate under the circumstances. Nothing contained in this Agreement, however, is intended to nor shall it be construed to require the General Partner (including the Conflicts Committee) to consider the interests of any Person other than the Partnership. In the absence of bad faith by the General Partner, the resolution, action or terms so made, taken or provided by the General Partner with respect to such matter shall not constitute a breach of this Agreement or any other agreement contemplated herein or a breach of any standard of care or duty imposed herein or therein or, to the extent permitted by law, under the Delaware Act or any other law, rule or regulation.

(b) Whenever this Agreement or any other agreement contemplated hereby provides that the General Partner or any of its Affiliates is permitted or required to make a decision (i) in its “sole discretion” or “discretion,” that it deems “necessary or appropriate” or “necessary or advisable” or under a grant of similar authority or latitude, except as otherwise provided herein, the General Partner or such Affiliate shall be entitled to consider only such interests and factors as it desires and shall have no duty or obligation to give any consideration to any interest of, or factors affecting, the Partnership, any other Group Member, any Limited Partner or any Assignee, (ii) it may make such decision in its sole discretion (regardless of whether there is a reference to “sole discretion” or “discretion”) unless another express standard is provided for, or (iii) in “good faith” or under another express standard, the General Partner or such Affiliate shall act under such express standard and shall not be subject to any other or different standards imposed by this Agreement, the Operating Partnership Agreement, the limited liability company or partnership agreement of any other Group Member, any other agreement contemplated hereby or under the Delaware Act or any other law, rule or regulation. In addition, any actions taken by

the General Partner or such Affiliate consistent with the standards of “reasonable discretion” set forth in the definitions of Available Cash or Operating Surplus shall not constitute a breach of any duty of the General Partner to the Partnership or the Limited Partners. The General Partner shall have no duty, express or implied, to sell or otherwise dispose of any asset of the Partnership Group other than in the ordinary course of business. No borrowing by any Group Member or the approval thereof by the General Partner shall be deemed to constitute a breach of any duty of the General Partner to the Partnership or the Limited Partners by reason of the fact that the purpose or effect of such borrowing is directly or indirectly to (A) enable distributions to the General Partner or its Affiliates (including in their capacities as Limited Partners) to exceed 2% of the total amount distributed to all partners or (B) hasten the expiration of the Subordination Period or the conversion of any Subordinated Units into Common Units.

(c) Whenever a particular transaction, arrangement or resolution of a conflict of interest is required under this Agreement to be “fair and reasonable” to any Person, the fair and reasonable nature of such transaction, arrangement or resolution shall be considered in the context of all similar or related transactions.

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

Section 7.10 Other Matters Concerning the General Partner.

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

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

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

(d) Any standard of care and duty imposed by this Agreement or under the Delaware Act or any applicable law, rule or regulation shall be modified, waived or limited, to the extent permitted by law, as required to permit the General Partner to act under this Agreement or any other agreement contemplated by this Agreement and to make any decision pursuant to the authority prescribed in this Agreement, so long as such action is reasonably believed by the General Partner to be in, or not inconsistent with, the best interests of the Partnership.

Section 7.11 Purchase or Sale of Partnership Securities.

The General Partner may cause the Partnership to purchase or otherwise acquire Partnership Securities; provided that, except as permitted pursuant to Section 4.10, the General Partner may not cause any Group Member to purchase Subordinated Units during the Subordination Period. As long as Partnership Securities are held by any Group Member, such Partnership Securities shall not be considered Outstanding for any purpose, except as otherwise provided herein. The General Partner or any Affiliate of the General Partner may also purchase or otherwise acquire and sell or otherwise dispose of Partnership Securities for its own account, subject to the provisions of Articles IV and X.

Section 7.12 Registration Rights of the General Partner and its Affiliates.

(a) If (i) the General Partner or any Affiliate of the General Partner (including for purposes of this Section 7.12, any Person that is an Affiliate of the General Partner at the date hereof notwithstanding that it may later cease to be an Affiliate of the General Partner) holds Partnership Securities that it desires to sell and (ii) Rule 144 of the Securities Act (or any successor rule or regulation to Rule 144) or another exemption from registration is not available to enable such holder of Partnership Securities (the “Holder”) to dispose of the number of Partnership Securities it desires to sell at the time it desires to do so without registration under the Securities Act, then upon the request of the General Partner or any of its Affiliates, the Partnership shall file with the Commission as promptly as practicable after receiving such request, and use all reasonable efforts to cause to become effective and remain effective for a period of not less than six months following its effective date or such shorter period as shall terminate when all Partnership Securities covered by such registration statement have been sold, a registration statement under the Securities Act registering the offering and sale of the number of Partnership Securities specified by the Holder; provided, however, that the Partnership shall not be required to effect more than three registrations pursuant to this Section 7.12(a); and provided further, however, that if the Conflicts Committee determines in its good faith judgment that a postponement of the requested registration for up to six months would be in the best interests of the Partnership and its Partners due to a pending transaction, investigation or other event, the filing of such registration statement or the effectiveness thereof may be deferred for up to six months, but not thereafter. In connection with any registration pursuant to the immediately preceding sentence, the Partnership shall promptly prepare and file (x) such documents as may be necessary to register or qualify the securities subject to such registration under the securities laws of such states as the Holder shall reasonably request; provided, however, that no such qualification shall be required in any jurisdiction where, as a result thereof, the Partnership would become subject to general service of process or to taxation or qualification to do business as a foreign corporation or partnership doing business in such jurisdiction solely as a result of such registration, and (y) such documents as may be necessary to apply for listing or to list the Partnership Securities subject to such registration on such National Securities Exchange as the Holder shall reasonably request, and do any and all other acts and things that may reasonably be necessary or advisable to enable the Holder to consummate a public sale of such Partnership Securities in such states. Except as set forth in Section 7.12(c), all costs and expenses of any such registration and offering (other than the underwriting discounts and commissions) shall be paid by the Partnership, without reimbursement by the Holder.

(b) If the Partnership shall at any time propose to file a registration statement under the Securities Act for an offering of equity securities of the Partnership for cash (other than an offering relating solely to an employee benefit plan), the Partnership shall use all reasonable efforts to include such number or amount of securities held by the Holder in such registration statement as the Holder shall request. If the proposed offering pursuant to this Section 7.12(b) shall be an underwritten offering, then, in the event that the managing underwriter or managing underwriters of such offering advise the Partnership and the Holder in writing that in their opinion the inclusion of all or some of the Holder’s Partnership Securities would adversely and materially affect the success of the offering, the Partnership shall include in such offering only that number or amount, if any, of securities held by the Holder that, in the opinion of the managing underwriter or managing underwriters, will not so adversely and materially affect the offering. Except as set forth in Section 7.12(c), all costs and expenses of any such registration and offering (other than the underwriting discounts and commissions) shall be paid by the Partnership, without reimbursement by the Holder.

(c) If underwriters are engaged in connection with any registration referred to in this Section 7.12, the Partnership shall provide indemnification, representations, covenants, opinions and other assurance to the underwriters in form and substance reasonably satisfactory to such underwriters. Further, in addition to and not in limitation of the Partnership’s obligation under Section 7.7, the Partnership shall, to the fullest extent permitted by law, indemnify and hold harmless the Holder, its officers, directors and each Person who controls the Holder (within the meaning of the Securities Act) and any agent thereof (collectively, “Indemnified Persons”) against any losses, claims, demands, actions, causes of action, assessments, damages, liabilities (joint or several), costs and expenses (including interest, penalties and reasonable attorneys’ fees and disbursements), resulting to, imposed upon, or incurred by the Indemnified Persons, directly or indirectly, under the Securities Act or otherwise (hereinafter referred to in this Section 7.12(c) as a “claim” and in the plural as “claims”) based upon, arising out of or resulting from any untrue statement or alleged untrue statement of any material fact contained in any registration statement under which any Partnership Securities were registered under the Securities Act or any state securities or Blue Sky laws, in any preliminary prospectus (if used prior to the effective date of such registration statement), or in any summary or final prospectus or in any amendment or supplement thereto (if used during the period the Partnership is required to keep the registration statement current), or arising out of, based upon or resulting from the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements made therein not misleading; provided, however, that the Partnership shall not be liable to any Indemnified Person to the extent that any such claim arises out of, is based upon or results from an untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement, such preliminary, summary or final prospectus or such amendment or supplement, in reliance upon and in conformity with written information furnished to the Partnership by or on behalf of such Indemnified Person specifically for use in the preparation thereof.

(d) The provisions of Section 7.12(a) and 7.12(b) shall continue to be applicable with respect to the General Partner (and any of the General Partner’s Affiliates) after it ceases to be a Partner of the Partnership, during a period of two years subsequent to the effective date of such cessation and for so long thereafter as is required for the Holder to sell all of the Partnership Securities with respect to which it has requested during such two-year period inclusion in a

registration statement otherwise filed or that a registration statement be filed; provided, however, that the Partnership shall not be required to file successive registration statements covering the same Partnership Securities for which registration was demanded during such two-year period. The provisions of Section 7.12(c) shall continue in effect thereafter.

(e) Any request to register Partnership Securities pursuant to this Section 7.12 shall (i) specify the Partnership Securities intended to be offered and sold by the Person making the request, (ii) express such Person’s present intent to offer such Partnership Securities for distribution, (iii) describe the nature or method of the proposed offer and sale of Partnership Securities, and (iv) contain the undertaking of such Person to provide all such information and materials and take all action as may be required in order to permit the Partnership to comply with all applicable requirements in connection with the registration of such Partnership Securities.

Section 7.13 Reliance by Third Parties.

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

(a) The Partnership shall make the election under Section 754 of the Code in accordance with applicable regulations thereunder, subject to the reservation of the right to seek to revoke any such election upon the General Partner’s determination that such revocation is in the best interests of the Limited Partners. Notwithstanding any other provision herein contained, for the purposes of computing the adjustments under Section 743(b) of the Code, the General Partner shall be authorized (but not required) to adopt a convention whereby the price paid by a transferee of a Limited Partner Interest will be deemed to be the lowest quoted closing price of the Limited Partner Interests on any National Securities Exchange on which such Limited Partner Interests are traded during the calendar month in which such transfer is deemed to occur pursuant to Section 6.2(g) without regard to the actual price paid by such transferee.

(b) The Partnership shall elect to deduct expenses incurred in organizing the Partnership ratably over a sixty-month period as provided in Section 709 of the Code.

Such Assignee shall become a Substituted Limited Partner (x) at such time as the General Partner consents thereto, which consent may be given or withheld in the General Partner’s discretion, and (y) when any such admission is shown on the books and records of the Partnership. If such consent is withheld, such transferee shall be an Assignee. An Assignee shall have an interest in the Partnership equivalent to that of a Limited Partner with respect to allocations and distributions, including liquidating distributions, of the Partnership. With respect to voting rights attributable to Limited Partner Interests that are held by Assignees, the General Partner shall be deemed to be the Limited Partner with respect thereto and shall, in exercising the voting rights in respect of such Limited Partner Interests on any matter, vote such Limited Partner Interests at the written direction of the Assignee who is the Record Holder of such Limited Partner Interests. If no such written direction is received, such Limited Partner Interests will not be voted. An Assignee shall have no other rights of a Limited Partner.

Partner Interest pursuant to Section 4.6; provided, however, that no such successor shall be admitted to the Partnership until compliance with the terms of Section 4.6 has occurred and such successor has executed and delivered such other documents or instruments as may be required to effect such admission.

To effect the admission to the Partnership of any Partner, the General Partner shall take all steps necessary and appropriate under the Delaware Act to amend the records of the Partnership to reflect such admission and, if necessary, to prepare as soon as practicable an amendment to this Agreement and, if required by law, the General Partner shall prepare and file an amendment to the Certificate of Limited Partnership, and the General Partner may for this purpose, among others, exercise the power of attorney granted pursuant to Section 2.6.

(b) Withdrawal of the General Partner from the Partnership upon the occurrence of an Event of Withdrawal shall not constitute a breach of this Agreement under the following circumstances: (i) at any time during the period beginning on the Closing Date and ending at 12:00 midnight, Eastern Standard Time, on December 31, 2012, the General Partner voluntarily withdraws by giving at least 90 days’ advance notice of its intention to withdraw to the Limited Partners; provided that prior to the effective date of such withdrawal, the withdrawal is approved by Unitholders holding at least a majority of the Outstanding Common Units (excluding Common Units held by the General Partner and its Affiliates) and the General Partner delivers to the Partnership an Opinion of Counsel (“Withdrawal Opinion of Counsel”) that such withdrawal (following the selection of the successor General Partner) would not result in the loss of the limited liability of any Limited Partner or any Group Member or cause any Group Member to be treated as an association taxable as a corporation or otherwise to be taxed as an entity for federal income tax purposes (to the extent not previously treated as such); (ii) at any time after 12:00 midnight, Eastern Standard Time, on December 31, 2012, the General Partner voluntarily withdraws by giving at least 90 days’ advance notice to the Unitholders, such withdrawal to take effect on the date specified in such notice; (iii) at any time that the General Partner ceases to be the General Partner pursuant to Section 11.1(a)(ii) or is removed pursuant to Section 11.2; or (iv) notwithstanding clause (i) of this sentence, at any time that the General Partner voluntarily withdraws by giving at least 90 days’ advance notice of its intention to withdraw to the Limited Partners, such withdrawal to take effect on the date specified in the notice, if at the time such notice is given one Person and its Affiliates (other than the General Partner and its Affiliates) own beneficially or of record or control at least 50% of the Outstanding Units. The withdrawal of the General Partner from the Partnership upon the occurrence of an Event of Withdrawal shall also constitute the withdrawal of the General Partner as general partner or managing member, to the extent applicable, of the other Group Members. If the General Partner gives a notice of withdrawal pursuant to Section 11.1(a)(i), the holders of a Unit Majority, may, prior to the effective date of such withdrawal, elect a successor General Partner. The Person so elected as successor General Partner shall automatically become the successor general partner or managing member, to the extent applicable, of the other Group Members of which the General Partner is a general partner or a managing member. If, prior to the effective date of the General Partner’s withdrawal, a successor is not selected by the Unitholders as provided herein or the Partnership does not receive a Withdrawal Opinion of Counsel, the Partnership shall be dissolved in accordance with Section 12.1. Any successor General Partner elected in accordance with the terms of this Section 11.1 shall be subject to the provisions of Section 10.3.

Section 11.2 Removal of the General Partner.

The General Partner may be removed if such removal is approved by the Unitholders holding at least 66?% of the Outstanding Units (including Units held by the General Partner and its Affiliates). Any such action by such holders for removal of the General Partner must also provide for the election of a successor General Partner by the Unitholders holding a majority of the outstanding Common Units voting as a class and a majority of the outstanding Senior Subordinated Units, Senior Subordinated Series B Units, Senior Subordinated Series C Units and the Subordinated Units voting as a single class (including Units held by the General Partner and its Affiliates). Such removal shall be effective immediately following the admission of a successor General Partner pursuant to Section 10.3. The removal of the General Partner shall also automatically constitute the removal of the General Partner as general partner or managing member, to the extent applicable, of the other Group Members of which the General Partner is a general partner or a managing member. If a Person is elected as a successor General Partner in accordance with the terms of this Section 11.2, such Person shall, upon admission pursuant to Section 10.3, automatically become a successor general partner or managing member, to the extent applicable, of the other Group Members of which the General Partner is a general partner or a managing member. The right of the holders of Outstanding Units to remove the General Partner shall not exist or be exercised unless the Partnership has received an opinion opining as to the matters covered by a Withdrawal Opinion of Counsel. Any successor General Partner elected in accordance with the terms of this Section 11.2 shall be subject to the provisions of Section 10.3.

Section 11.3 Interest of Departing Partner and Successor General Partner.

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

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

(b) If the Combined Interest is not purchased in the manner set forth in Section 11.3(a), the Departing Partner (or its transferee) shall become a Limited Partner and its Combined Interest shall be converted into Common Units pursuant to a valuation made by an investment banking firm or other independent expert selected pursuant to Section 11.3(a), without reduction in such Partnership Interest (but subject to proportionate dilution by reason of the admission of its successor). Any successor General Partner shall indemnify the Departing Partner (or its transferee) as to all debts and liabilities of the Partnership arising on or after the date on which the Departing Partner (or its transferee) becomes a Limited Partner. For purposes of this Agreement, conversion of the Combined Interest of the Departing Partner to Common Units will be characterized as if the Departing Partner (or its transferee) contributed its Combined Interest to the Partnership in exchange for the newly issued Common Units.

(c) If a successor General Partner is elected in accordance with the terms of Section 11.1 or 11.2 and the option described in Section 11.3(a) is not exercised by the party entitled to do so, the successor General Partner shall, at the effective date of its admission to the Partnership, contribute to the Partnership cash in the amount equal to 2/98ths of the Net Agreed Value of the Partnership’s assets on such date. In such event, such successor General Partner shall, subject to the following sentence, be entitled to 2% of all Partnership allocations and distributions to which the Departing Partner was entitled. In addition, the successor General Partner shall cause this Agreement to be amended to reflect that, from and after the date of such successor General Partner’s admission, the successor General Partner’s interest in all Partnership distributions and allocations shall be 2%.

Section 11.4 Termination of Subordination Period, Conversion of Subordinated Units and Extinguishment of Cumulative Common Unit Arrearages.

Notwithstanding any provision of this Agreement, if the General Partner is removed as general partner of the Partnership under circumstances where Cause does not exist and Units held by the General Partner and its Affiliates are not voted in favor of such removal, (i) the

Subordination Period will end and all Outstanding Subordinated Units will immediately and automatically convert into Common Units on a one-for-one basis and (ii) all Cumulative Common Unit Arrearages on the Common Units will be extinguished.

Section 11.5 Withdrawal of Limited Partners.

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

ARTICLE XII

DISSOLUTION AND LIQUIDATION

Section 12.1 Dissolution.

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

(a) an Event of Withdrawal of the General Partner as provided in Section 11.1(a) (other than Section 11.1(a)(ii)), unless a successor is elected and an Opinion of Counsel is received as provided in Section 11.1(b) or 11.2 and such successor is admitted to the Partnership pursuant to Section 10.3;

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

(d) the sale of all or substantially all of the assets and properties of the Partnership Group.

Section 12.2 Continuation of the Business of the Partnership After Dissolution.

Upon (a) dissolution of the Partnership following an Event of Withdrawal caused by the withdrawal or removal of the General Partner as provided in Section 11.1(a)(i) or (iii) and the failure of the Partners to select a successor to such Departing Partner pursuant to Section 11.1 or 11.2, then within 90 days thereafter, or (b) dissolution of the Partnership upon an event constituting an Event of Withdrawal as defined in Section 11.1(a)(iv), (v) or (vi), then, to the maximum extent permitted by law, within 180 days thereafter, the holders of a Unit Majority may elect to reconstitute the Partnership and continue its business on the same terms and conditions set forth in this Agreement by forming a new limited partnership on terms identical to

those set forth in this Agreement and having as the successor General partner a Person approved by the holders of a Unit Majority. Unless such an election is made within the applicable time period as set forth above, the Partnership shall conduct only activities necessary to wind up its affairs. If such an election is so made, then:

(i) the reconstituted Partnership shall continue unless earlier dissolved in accordance with this Article XII;

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

(iii) all necessary steps shall be taken to cancel this Agreement and the Certificate of Limited Partnership and to enter into and, as necessary, to file a new partnership agreement and certificate of limited partnership, and the successor General Partner may for this purpose exercise the powers of attorney granted the General Partner pursuant to Section 2.6; provided, that the right of the holders of a Unit Majority to approve a successor General Partner and to reconstitute and to continue the business of the Partnership shall not exist and may not be exercised unless the Partnership has received an Opinion of Counsel that (x) the exercise of the right would not result in the loss of limited liability of any Limited Partner and (y) neither the Partnership, the reconstituted limited partnership nor the Operating Partnership or any other Group Member would be treated as an association taxable as a corporation or otherwise be taxable as an entity for federal income tax purposes upon the exercise of such right to continue.

Section 12.3 Liquidator.

Upon dissolution of the Partnership, unless the Partnership is continued under an election to reconstitute and continue the Partnership pursuant to Section 12.2, the General Partner shall select one or more Persons to act as Liquidator. The Liquidator (if other than the General Partner) shall be entitled to receive such compensation for its services as may be approved by holders of at least a majority of the Outstanding Common Units, Senior Subordinated Units, Senior Subordinated Series B Units, Senior Subordinated Series C Units and Subordinated Units voting as a single class. The Liquidator (if other than the General Partner) shall agree not to resign at any time without 15 days’ prior notice and may be removed at any time, with or without cause, by notice of removal approved by holders of at least a majority of the Outstanding Common Units, Senior Subordinated Units, Senior Subordinated Series B Units, Senior Subordinated Series C Units and Subordinated Units voting as a single class. Upon dissolution, removal or resignation of the Liquidator, a successor and substitute Liquidator (who shall have and succeed to all rights, powers and duties of the original Liquidator) shall within 30 days thereafter be approved by holders of at least a majority of the Outstanding Common Units, Senior Subordinated Units, Senior Subordinated Series B Units, Senior Subordinated Series C Units and Subordinated Units voting as a single class. The right to approve a successor or substitute Liquidator in the manner provided herein shall be deemed to refer also to any such successor or substitute Liquidator approved in the manner herein provided. Except as expressly provided in this Article XII, the Liquidator approved in the manner provided herein shall have

and may exercise, without further authorization or consent of any of the parties hereto, all of the powers conferred upon the General Partner under the terms of this Agreement (but subject to all of the applicable limitations, contractual and otherwise, upon the exercise of such powers, other than the limitation on sale set forth in Section 7.3(b)) to the extent necessary or desirable in the good faith judgment of the Liquidator to carry out the duties and functions of the Liquidator hereunder for and during such period of time as shall be reasonably required in the good faith judgment of the Liquidator to complete the winding up and liquidation of the Partnership as provided for herein.

Section 12.4 Liquidation.

The Liquidator shall proceed to dispose of the assets of the Partnership, discharge its liabilities, and otherwise wind up its affairs in such manner and over such period as the Liquidator determines to be in the best interest of the Partners, subject to Section 17-804 of the Delaware Act and the following:

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

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

(c) All property and all cash in excess of that required to discharge liabilities as provided in Section 12.4(b) shall be distributed to the Partners in accordance with, and to the extent of, the positive balances in their respective Capital Accounts, as determined after taking into account all Capital Account adjustments (other than those made by reason of distributions pursuant to this Section 12.4(c)) for the taxable year of the Partnership during which the liquidation of the Partnership occurs (with such date of occurrence being determined pursuant to Treasury Regulation Section 1.704-1(b)(2)(ii)(g)), and such distribution shall be made by the end of such taxable year (or, if later, within 90 days after said date of such occurrence).

Section 12.5 Cancellation of Certificate of Limited Partnership.

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

Section 12.6 Return of Contributions.

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

Section 12.7 Waiver of Partition.

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

Section 12.8 Capital Account Restoration.

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

Amendments to this Agreement may be proposed only by or with the consent of the General Partner which consent may be given or withheld in its sole discretion.

(b) Notwithstanding the provisions of Sections 13.1 and 13.2, no amendment to this Agreement may (i) enlarge the obligations of any Limited Partner without its consent, unless such shall be deemed to have occurred as a result of an amendment approved pursuant to Section 13.3(c), (ii) enlarge the obligations of, restrict in any way any action by or rights of, or reduce in any way the amounts distributable, reimbursable or otherwise payable to, the General Partner or any of its Affiliates without its consent, which consent may be given or withheld in its sole discretion, (iii) change Section 12.1(b), or (iv) change the term of the Partnership or, except as set forth in Section 12.1(b), give any Person the right to dissolve the Partnership.

(d) Notwithstanding any other provision of this Agreement, except for amendments pursuant to Section 13.1 and except as otherwise provided by Section 14.3(b), no amendments shall become effective without the approval of the holders of at least 90% of the Outstanding Units voting as a single class unless the Partnership obtains an Opinion of Counsel to the effect

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

Section 13.4 Special Meetings.

All acts of Limited Partners to be taken pursuant to this Agreement shall be taken in the manner provided in this Article XIII. Special meetings of the Limited Partners may be called by the General Partner or by Limited Partners owning 20% or more of the Outstanding Units of the class or classes for which a meeting is proposed. Limited Partners shall call a special meeting by delivering to the General Partner one or more requests in writing stating that the signing Limited Partners wish to call a special meeting and indicating the general or specific purposes for which the special meeting is to be called. Within 60 days after receipt of such a call from Limited Partners or within such greater time as may be reasonably necessary for the Partnership to comply with any statutes, rules, regulations, listing agreements or similar requirements governing the holding of a meeting or the solicitation of proxies for use at such a meeting, the General Partner shall send a notice of the meeting to the Limited Partners either directly or indirectly through the Transfer Agent. A meeting shall be held at a time and place determined by the General Partner on a date not less than 10 days nor more than 60 days after the mailing of notice of the meeting. Limited Partners shall not vote on matters that would cause the Limited Partners to be deemed to be taking part in the management and control of the business and affairs of the Partnership so as to jeopardize the Limited Partners’ limited liability under the Delaware Act or the law of any other state in which the Partnership is qualified to do business.

Section 13.5 Notice of a Meeting.

Notice of a meeting called pursuant to Section 13.4 shall be given to the Record Holders of the class or classes of Units for which a meeting is proposed in writing by mail or other means of written communication in accordance with Section 16.1. The notice shall be deemed to have been given at the time when deposited in the mail or sent by other means of written communication.

Section 13.6 Record Date.

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

Section 13.7 Adjournment.

When a meeting is adjourned to another time or place, notice need not be given of the adjourned meeting and a new Record Date need not be fixed, if the time and place thereof are announced at the meeting at which the adjournment is taken, unless such adjournment shall be for more than 45 days. At the adjourned meeting, the Partnership may transact any business which might have been transacted at the original meeting. If the adjournment is for more than 45 days or if a new Record Date is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given in accordance with this Article XIII.

Section 13.8 Waiver of Notice; Approval of Meeting; Approval of Minutes.

The transactions of any meeting of Limited Partners, however called and noticed, and whenever held, shall be as valid as if it had occurred at a meeting duly held after regular call and notice, if a quorum is present either in person or by proxy, and if, either before or after the meeting, Limited Partners representing such quorum who were present in person or by proxy and entitled to vote, sign a written waiver of notice or an approval of the holding of the meeting or an approval of the minutes thereof. All waivers and approvals shall be filed with the Partnership records or made a part of the minutes of the meeting. Attendance of a Limited Partner at a meeting shall constitute a waiver of notice of the meeting, except when the Limited Partner does not approve, at the beginning of the meeting, of the transaction of any business because the meeting is not lawfully called or convened; and except that attendance at a meeting is not a waiver of any right to disapprove the consideration of matters required to be included in the notice of the meeting, but not so included, if the disapproval is expressly made at the meeting.

Section 13.9 Quorum.

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

Units deemed owned by the General Partner) represented either in person or by proxy, but no other business may be transacted, except as provided in Section 13.7.

Section 13.10 Conduct of a Meeting.

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

Section 13.11 Action Without a Meeting.

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

Section 13.12 Voting and Other Rights.

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

(b) With respect to Units that are held for a Person’s account by another Person (such as a broker, dealer, bank, trust company or clearing corporation, or an agent of any of the foregoing), in whose name such Units are registered, such other Person shall, in exercising the voting rights in respect of such Units on any matter, and unless the arrangement between such Persons provides otherwise, vote such Units in favor of, and at the direction of, the Person who is the beneficial owner, and the Partnership shall be entitled to assume it is so acting without further inquiry. The provisions of this Section 13.12(b) (as well as all other provisions of this Agreement) are subject to the provisions of Section 4.3.

(e) a statement of any changes in the constituent documents or the adoption of new constituent documents (the articles or certificate of incorporation, articles of trust, declaration of trust, certificate or agreement of limited partnership or other similar charter or governing document) of the Surviving Business Entity to be effected by such merger or consolidation;

(f) the effective time of the merger, which may be the date of the filing of the certificate of merger pursuant to Section 14.4 or a later date specified in or determinable in accordance with the Merger Agreement (provided, that if the effective time of the merger is to be later than the date of the filing of the certificate of merger, the effective time shall be fixed no later than the time of the filing of the certificate of merger and stated therein); and

(g) such other provisions with respect to the proposed merger or consolidation as are deemed necessary or appropriate by the General Partner.

Section 14.3 Approval by Limited Partners of Merger or Consolidation.

(a) Except as provided in Section 14.3(d), the General Partner, upon its approval of the Merger Agreement, shall direct that the Merger Agreement be submitted to a vote of Limited Partners, whether at a special meeting or by written consent, in either case in accordance with the requirements of Article XIII. A copy or a summary of the Merger Agreement shall be included in or enclosed with the notice of a special meeting or the written consent.

(b) Except as provided in Section 14.3(d), the Merger Agreement shall be approved upon receiving the affirmative vote or consent of the holders of a Unit Majority unless the Merger Agreement contains any provision that, if contained in an amendment to this Agreement, the provisions of this Agreement or the Delaware Act would require for its approval the vote or consent of a greater percentage of the Outstanding Units or of any class of Limited Partners, in which case such greater percentage vote or consent shall be required for approval of the Merger Agreement.

(c) Except as provided in Section 14.3(d), after such approval by vote or consent of the Limited Partners, and at any time prior to the filing of the certificate of merger pursuant to

Section 14.4, the merger or consolidation may be abandoned pursuant to provisions therefor, if any, set forth in the Merger Agreement.

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

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

Section 15.1 Right to Acquire Limited Partner Interests.

(a) Notwithstanding any other provision of this Agreement, if at any time more than 80% of the total Limited Partner Interests of any class then Outstanding is held by the General Partner and its Affiliates, the General Partner shall then have the right, which right it may assign and transfer in whole or in part to the Partnership or any Affiliate of the General Partner, exercisable in its sole discretion, to purchase all, but not less than all, of such Limited Partner Interests of such class then Outstanding held by Persons other than the General Partner and its Affiliates, at the greater of (x) the Current Market Price as of the date three days prior to the date that the notice described in Section 15.1(b) is mailed and (y) the highest price paid by the General Partner or any of its Affiliates for any such Limited Partner Interest of such class purchased during the 90-day period preceding the date that the notice described in Section 15.1(b) is mailed. As used in this Agreement, (i) “Current Market Price” as of any date of any class of Limited Partner Interests means the average of the daily Closing Prices (as hereinafter defined) per Limited Partner Interest of such class for the 20 consecutive Trading Days (as hereinafter defined) immediately prior to such date; (ii) “Closing Price” for any day means the last sale price on such day, regular way, or in case no such sale takes place on such day, the average of the closing bid and asked prices on such day, regular way, in either case as reported in the principal consolidated transaction reporting system with respect to securities listed or admitted for trading on the principal National Securities Exchange (other than the Nasdaq Stock Market) on which such Limited Partner Interests of such class are listed or admitted to trading or, if such Limited Partner Interests of such class are not listed or admitted to trading on any National Securities Exchange (other than the Nasdaq Stock Market), the last quoted price on such day or, if not so quoted, the average of the high bid and low asked prices on such day in the over-the-counter market, as reported by the Nasdaq Stock Market or such other system then in use, or, if on any such day such Limited Partner Interests of such class are not quoted by any such organization, the average of the closing bid and asked prices on such day as furnished by a professional market maker making a market in such Limited Partner Interests of such class selected by the General Partner, or if on any such day no market maker is making a market in such Limited Partner Interests of such class, the fair value of such Limited Partner Interests on such day as determined reasonably and in good faith by the General Partner; and (iii) “Trading Day” means a day on which the principal National Securities Exchange on which such Limited Partner Interests of any class are listed or admitted to trading is open for the transaction of business or, if Limited Partner Interests of a class are not listed or admitted to trading on any National Securities Exchange, a day on which banking institutions in New York City generally are open.

(b) If the General Partner, any Affiliate of the General Partner or the Partnership elects to exercise the right to purchase Limited Partner Interests granted pursuant to Section 15.1(a), the General Partner shall deliver to the Transfer Agent notice of such election to purchase (the “Notice of Election to Purchase”) and shall cause the Transfer Agent to mail a copy of such Notice of Election to Purchase to the Record Holders of Limited Partner Interests of such class (as of a Record Date selected by the General Partner) at least 10, but not more than 60,

days prior to the Purchase Date. Such Notice of Election to Purchase shall also be published for a period of at least three consecutive days in at least two daily newspapers of general circulation printed in the English language and published in the Borough of Manhattan, New York. The Notice of Election to Purchase shall specify the Purchase Date and the price (determined in accordance with Section 15.1(a)) at which Limited Partner Interests will be purchased and state that the General Partner, its Affiliate or the Partnership, as the case may be, elects to purchase such Limited Partner Interests, upon surrender of Certificates representing such Limited Partner Interests in exchange for payment, at such office or offices of the Transfer Agent as the Transfer Agent may specify, or as may be required by any National Securities Exchange on which such Limited Partner Interests are listed or admitted to trading. Any such Notice of Election to Purchase mailed to a Record Holder of Limited Partner Interests at his address as reflected in the records of the Transfer Agent shall be conclusively presumed to have been given regardless of whether the owner receives such notice. On or prior to the Purchase Date, the General Partner, its Affiliate or the Partnership, as the case may be, shall deposit with the Transfer Agent cash in an amount sufficient to pay the aggregate purchase price of all of such Limited Partner Interests to be purchased in accordance with this Section 15.1. If the Notice of Election to Purchase shall have been duly given as aforesaid at least 10 days prior to the Purchase Date, and if on or prior to the Purchase Date the deposit described in the preceding sentence has been made for the benefit of the holders of Limited Partner Interests subject to purchase as provided herein, then from and after the Purchase Date, notwithstanding that any Certificate shall not have been surrendered for purchase, all rights of the holders of such Limited Partner Interests (including any rights pursuant to Articles IV, V, VI, and XII) shall thereupon cease, except the right to receive the purchase price (determined in accordance with Section 15.1(a)) for Limited Partner Interests therefor, without interest, upon surrender to the Transfer Agent of the Certificates representing such Limited Partner Interests, and such Limited Partner Interests shall thereupon be deemed to be transferred to the General Partner, its Affiliate or the Partnership, as the case may be, on the record books of the Transfer Agent and the Partnership, and the General Partner or any Affiliate of the General Partner, or the Partnership, as the case may be, shall be deemed to be the owner of all such Limited Partner Interests from and after the Purchase Date and shall have all rights as the owner of such Limited Partner Interests (including all rights as owner of such Limited Partner Interests pursuant to Articles IV, V, VI and XII).

(c) At any time from and after the Purchase Date, a holder of an Outstanding Limited Partner Interest subject to purchase as provided in this Section 15.1 may surrender his Certificate evidencing such Limited Partner Interest to the Transfer Agent in exchange for payment of the amount described in Section 15.1(a), therefor, without interest thereon.

Section 16.8 Applicable Law.

This Agreement shall be construed in accordance with and governed by the laws of the State of Delaware, without regard to the principles of conflicts of law.
