This Agreement may be terminated and the transactions contemplated hereby abandoned by written notice at any time prior to the Closing in any of the following manners: (a) by any Party concurrently with any permitted termination of the Acquisition Agreement; (b) by written consent of each of the Parties; (c) by any Party if the Closing has not occurred on or before February 15, 2004, unless such failure to close resulted from a breach of this Agreement by the Party or its Affiliate seeking to terminate this Agreement pursuant to this Section 8.1(c); (d) by any Party if (i) there is any statute, rule or regulation that makes consummation of the transactions contemplated hereby or the operation of the La Grange Business or Heritage Business illegal or otherwise prohibited or (ii) a Governmental Authority (A) has issued an order, decree or ruling or taken any other action restraining, enjoining or otherwise prohibiting the consummation of the transactions contemplated hereby, and such order, decree, ruling or other action shall have become final and nonappealable or (B) has made any order, decree, ruling or other action consenting to or approving consummation of the transactions contemplated hereby contingent or conditional in any manner that has a Heritage Material Adverse Effect or a La Grange Material Adverse Effect; (e) by any Party, if there has been any violation or breach by any other Party (other than an Affiliate or related party of the first party) of any representation, warranty, covenant or agreement contained in this Agreement that has rendered impossible the satisfaction of any condition to the obligations of such other Party set forth in Section 7.1 or Section 7.2 and such violation or breach has neither been cured within 30 days after notice by such first Party to the other Party nor waived by the first Party; (f) by any Party, if any other event shall occur that shall render the satisfaction of any such condition to the obligations of any other Party (other than an Affiliate or related party of the first party) impossible and such condition has not been waived by the other Parties; (g) by La Grange, if any material amendment is made by the Heritage Parties in accordance with Section 6.8; (h) by the Heritage Parties, if any material amendment is made by La Grange in accordance with Section 6.8; (i) by La Grange, if the Average Market Value is less than $29.50, or by Heritage MLP, if the Average Market Value is greater than $38.50; 53 (j) by La Grange, if the general partner of La Grange reasonably determines at any time after January 10, 2004 that it is not possible for the Heritage Parties to fulfill any of the conditions described in Sections 7.1(m), 7.1(n) or 7.1(o) on or before the Closing Date on terms and conditions reasonably acceptable to La Grange; and (k) by the Heritage Parties acting through the Special Committee, if the Special Committee determines that a possible alternative would constitute a Superior Transaction. 8.2 EFFECT OF TERMINATION. In the event of the termination of this Agreement pursuant to Section 8.1 by any Party, written notice thereof shall forthwith be given to the other Parties specifying the provision hereof pursuant to which such termination is made. Except as provided in Section 8.5 of this Agreement, in the event of termination of this Agreement for any reason, this Agreement and the Acquisition Agreement shall become void and have no effect, except that the agreements contained in this Section 8.2 and Section 8.5 and in Section 6.5 and Article 10 shall survive the termination hereof. Nothing contained in this Section 8.2 shall relieve any Party from liability for any willful breach of this Agreement. In the event of termination, each of the Parties shall be responsible for its own expenses and costs. 8.3 AMENDMENT. This Agreement may not be amended except by an instrument in writing signed by each of the Parties. 8.4 WAIVER.

Any agreement on the part of a Party to any such waiver shall be valid only if set forth in an instrument in writing signed by or on behalf of such Party.

Any payment required to be made pursuant to this Section 8.5 shall be made by wire transfer of immediately available funds to an account designated by La Grange in writing to Heritage MLP. 54 ARTICLE 9 SURVIVAL OF REPRESENTATIONS 9.1 INDEMNIFICATION OBLIGATIONS OF LA GRANGE. (a) La Grange shall indemnify each of the Heritage Parties and any of their owners, partners, officers, agents and their respective Affiliates and controlling Persons (the "Heritage Indemnified Parties"), as the case may be, and hold such Persons harmless against and in respect of, any and all Losses arising out of, based upon or resulting from: (i) the breach of any representation or warranty of La Grange contained in or made pursuant to this Agreement (other than breaches and warranties set forth in Section 4.2, Section 4.3, Section 4.7, Section 4.19, and Section 4.23); (ii) the breach of any representation or warranty of La Grange contained in or made pursuant to Section 4.19 [Environmental Matters], and Section 4.23 [Investment Intent]; (iii) the breach of any representation or warranty of La Grange contained in or made pursuant to Section 4.2 [Capitalization of the La Grange Entities], Section 4.3 [Authority and Binding Agreement], and Section 4.7 [Title to La Grange Assets],; and (iv) the breach by La Grange or the failure by La Grange to observe or perform in any material respect, any of their covenants or agreements contained in Section 5.6, Section 5.7, Section 6.4, Section 6.5, Section 6.6, Section 6,10, Section 6.12, Section 6.13, Section 6.14 or Article 10 of this Agreement. (b) Notwithstanding the foregoing, La Grange will not have any obligation to indemnify any of the Heritage Parties or their Affiliates for Losses under Section 9.1(a)(i) or Section 9.1(a)(ii) unless and until the aggregate amount of all such Losses under Section 9.1(a)(i) or Section 9.1(a)(ii) exceeds $500,000 (regardless of whether, in the case of third party actions, suits or proceedings with respect to any of the foregoing, La Grange may have a meritorious defense), at and after which time La Grange shall be liable for all Losses in excess of $500,000 and which do not in the aggregate exceed $10,000,000; provided however, that any liabilities for which accruals have been made by La Grange on the La Grange Financial Statement shall be excluded in determining whether losses exceed $500,000. The rights and remedies of the Heritage Parties based upon, arising out of or otherwise in respect of any clause of this Section 9.1 or any representation, warranty or covenant in this Agreement shall in no way be limited by the fact that the act, omission, occurrence or other state of facts upon which any such claim is based may also be the subject matter of any representation, warranty or covenant in this Agreement that would not give rise to any rights or remedies of the Heritage Parties. 9.2 INDEMNIFICATION OBLIGATIONS OF THE HERITAGE PARTIES. (a) The Heritage Parties shall, jointly and severally, indemnify La Grange and any of its owners, partners, officers, agents and their respective Affiliates and controlling Persons (the "La Grange Indemnified Parties"), as the case may be, and hold such Persons harmless against and in respect of any and all Losses arising out of, based upon or resulting from: 55 (i) the breach of any representation or warranty of the Heritage Parties contained in or made pursuant to this Agreement (other than breaches and warranties set forth in Section 3.2, Section 3.3, Section 3.7, and Section 3.19); (ii) the breach of any representation or warranty of the Heritage Parties contained in or made pursuant to Section 3.19 [Environmental Matters]; (iii) the breach of any representations or warranty of the Heritage Parties contained in or made pursuant to Section 3.2 [Capitalization of the Heritage Entities], Section 3.3 [Authority and Binding Agreement], Section 3.7 [Title to Heritage Assets], and (iv) the breach by the Heritage Parties or the failure by the Heritage Parties to observe or perform in any material respect, any of its covenants or agreements contained in Section 5.6, Section 5.7, Section 6.4, Section 6.5, Section 6.6, Section 6,10, Section 6.12, Section 6.13, Section 6.14 or Article 10 of this Agreement. (b) Notwithstanding the foregoing, the Heritage Parties will not have any obligation to indemnify La Grange or its Affiliates for Losses under Section 9.2(a)(i) or Section 9.2(a)(ii) unless and until the aggregate amount of all such Losses under Section 9.2(a)(i) or Section 9.2(a)(ii) exceeds $500,000 (regardless of whether, in the case of third party actions, suits or proceedings with respect to any of the foregoing, the Heritage Parties may have a meritorious defense), at and after which time the Heritage Parties shall be liable for all Losses in excess of $500,000 and which do not in the aggregate exceed $10,000,000; provided however, that any liabilities for which accruals have been made by the Heritage Parties on the Heritage Financial Statements shall be excluded in determining whether losses exceed $500,000. The rights and remedies of La Grange based upon, arising out of or otherwise in respect of any clause of this Section 9.2 or any representation, warranty or covenant in this Agreement shall in no way be limited by the fact that the act, omission, occurrence or other state of facts upon which any such claim is based may also be the subject matter of any representation, warranty or covenant in this Agreement that would not give rise to any rights or remedies of La Grange. 9.3 INDEMNIFICATION PROCEDURES. (a) Promptly upon receipt by a Party indemnified under this Article 9 (an "Indemnified Party") of notice of the commencement of any action against such Indemnified Party (a "Third Party Action") in respect of which indemnity or reimbursement may be sought against a party required to make indemnification hereunder (an "Indemnifying Party"), such Indemnified Party shall notify the Indemnifying Party in writing of the commencement of such Third Party Action, but the failure so to notify the Indemnifying Party shall not relieve it of any liability which it may have to any Heritage Indemnified Party under Section 9.1 or any La Grange Indemnified Party under Section 9.2, as applicable, unless such failure actually and materially adversely affects the defense of such Third Party Action. In case notice of commencement of any such Third Party Action shall be given to the Indemnifying Party as above provided, the Indemnifying Party shall be entitled to participate in and to assume the defense of such action at its own expense, with counsel chosen by it that is reasonably satisfactory to the Indemnified Party; provided, however, that: 56 (i) the Indemnified Party shall be entitled to participate in the defense of such Third Party Action and to employ counsel at its own expense to assist in the handling of such Third Party Action (provided that the Indemnified Party shall be entitled to reimbursement for such expenses in accordance with subclauses (A) and (B) below in Section 9.3(b)); (ii) the Indemnifying Party shall obtain the prior written approval of the Indemnified Party, which approval shall not be unreasonably withheld or delayed, before entering into any settlement of such Third Party Action or ceasing to defend against such Third Party Action, if pursuant to or as a result of such settlement or cessation, injunctive or other equitable relief would be imposed against the Indemnified Party or the Indemnified Party would be adversely affected thereby; (iii) no Indemnifying Party shall consent to the entry of any judgment or enter into any settlement that does not include as an unconditional term thereof the giving by each claimant or plaintiff to each Indemnified Party of a release from all liability in respect of such Third Party Action; and (iv) the Indemnifying Party shall not be entitled to control the defense of any Third Party Action unless within 15 days after receipt of such written notice from the Indemnified Party, the Indemnifying Party confirms in writing its responsibility to indemnify the Indemnified Party with respect to such Third Party Action and reasonably demonstrates that it will be able to pay the full amount of the reasonably expected Losses in connection with any such Third Party Action. (b) Except as set forth in the following sentence, after written notice by the Indemnifying Party to the Indemnified Party of its election to assume control of the defense of any such Third Party Action in accordance with the foregoing and compliance by the Indemnifying Party with Section 9.3(d), (i) the Indemnifying Party shall not be liable to the Indemnified Party hereunder for any fees and expenses of counsel subsequently incurred by the Indemnified Party attributable to defending against such Third Party Action, and (ii) as long as the Indemnifying Party is reasonably contesting such Third Party Action in good faith, the Indemnified Party shall not admit any liability with respect to, or settle, compromise or discharge the claim underlying, such Third Party Action without the prior written consent of the Indemnifying Party (which consent shall not be unreasonably withheld or delayed). If (A) the Indemnifying Party does not assume control of the defense of such Third Party Action in accordance with this Section 9.3, or (B) the Indemnified Party has been advised in writing by counsel that representation of such Indemnified Party and the Indemnifying Party by the same counsel would be inappropriate under applicable standards of professional conduct (in which case the Indemnifying Party shall not have the right to assume the defense of such Third Party Action on behalf of the Indemnified Party), in each case the Indemnified Party shall have the right to defend and/or settle such Third Party Action in such manner as it may deem appropriate at the cost and expense of the Indemnifying Party, and the Indemnifying Party shall promptly reimburse the Indemnified Party therefore in accordance with this Article 9. The reimbursement of fees and expenses of counsel required by this Article 9 shall be made by periodic payments during the course of the investigation or defense, as and when bills are received or expenses incurred. 57 (c) If the Indemnifying Party shall be obligated to indemnify the Indemnified Party pursuant to this Article 9, the Indemnifying Party shall be subrogated to all rights of the Indemnified Party with respect to the claims to which such indemnification relates. If an Indemnified Party becomes entitled to any indemnification from an Indemnifying Party, such indemnification shall be made in cash upon demand. (d) The right of indemnification pursuant to this Article 9 shall constitute the sole and exclusive remedy of each of the Parties to this Agreement and their respective Affiliates, managers, directors, officers, members, employees and other agents and representatives, other than with respect to fraud or willful breach by a Party. So long as a claim for indemnification pursuant to this Article 9 is being contested in good faith by the Indemnifying Party or such claim shall otherwise remain unliquidated, such claim shall not affect any of the rights of the Indemnifying Party under this Agreement. 9.4 SURVIVAL. (a) All representations, warranties, covenants and agreements contained in this Agreement other than those set forth in Article 9 hereof, shall expire with and be terminated and extinguished by the Closing, and thereafter no Party nor any of such Party's owners, partners, officers, agents, and Affiliates shall have any liability with respect to such representations, warranties, covenants and agreements conducted by any Party and any information which any Party may receive (other than information identified in the Schedules to this Agreement). (b) The right to indemnification: (i) with respect to any breach or violation of any of the representations and warranties contained in Section 3.19 [Environmental Matters] and Section 4.19 [Environmental Matters] shall survive for two years following the Closing; (ii) with respect to any breach or violation of any of the representations and warranties contained in Section 3.7 [Title to Heritage Assets] and Section 4.7 [Title to La Grange Assets] shall survive for one year following the Closing; (iii) with respect to any breach or violation of any of the representations and warranties contained in Section 3.2, [Capitalization of the Heritage Entities], Section 3.3, [Authority and Binding Agreement], Section 4.2 [Capitalization of the La Grange Entities], Section 4.3 [Authority and Binding Agreement], and Section 4.23 [Investment Intent], shall survive indefinitely; and (iv) and with respect to any of the covenants and agreements contained in Section 5.6, Section 5.7, Section 6.4, Section 6.5, Section 6.6, Section 6.10, Section 6.12, Section 6.13, Section 6.14 or Article 10 of this Agreement, shall survive for the applicable statute of limitations. (c) The expiration of any survival period under this Agreement will not affect the liability of any Party under this Article 9 for any Loss as to which a bona fide claim has been asserted prior to the termination of such survival period. 58 9.5 NO SPECIAL OR CONSEQUENTIAL DAMAGES. No Party shall be entitled to recover special, consequential, exemplary or punitive damages from the other Parties, and each Party hereby waives any claim or right to special, consequential, exemplary or punitive damages hereunder, even if caused by the active, passive, sole, joint, concurrent or comparative negligence, strict liability, or other fault of any Party, other than fraud or intentional misconduct. ARTICLE 10 MISCELLANEOUS 10.1 NOTICES. All notices, requests, demands and other communications required or permitted to be given or made hereunder by any Party shall be in writing, and shall be delivered either personally, or by registered or certified mail (postage prepaid and return receipt requested) or by express courier or delivery service, or by telegram, telefax, telex or similar facsimile means, to the Parties, at the addresses (or at such other addresses as shall be specified by the Parties by like notice) set forth below: (a) If to La Grange: c/o ETC Holdings, LP 2838 Woodside Street Dallas, Texas Attention: Clay Kutch Facsimile: (214) 981-0701 with a copy to: Thompson & Knight L.L.P. 1700 Pacific Avenue, Suite 3300 Dallas, Texas 75201 Attention: Jeffrey A.

Any legal action, suit or proceeding in law or equity arising out of or relating to this Agreement or the transactions contemplated by this Agreement may only be instituted in any state or federal court located in the State of Texas, and each Party agrees not to 60 assert, by way of motion, as a defense or otherwise, in any such action, suit or proceeding, any claim that it is not subject personally to the jurisdiction of such court, that its property is exempt or immune from attachment or execution, that the action, suit or proceeding is brought in an inconvenient forum, that the venue of the action, suit or proceeding is improper or that this Agreement, or the subject matter hereof or thereof may not be enforced in or by such court. Each Party further irrevocably submits to the jurisdiction of any such court in any such action, suit or proceeding.
