     3.1 Effect of the Merger on Equity Securities

          (a) At the TEPPCO GP Effective Time, by virtue of the TEPPCO GP Merger and without any action on the part of any holder of TEPPCO GP Member Interests, subject to Section 3.1(b), all TEPPCO GP Member Interests issued and outstanding immediately prior to the TEPPCO GP Effective Time shall be converted into the right to receive aggregate consideration issued by Enterprise consisting of (1) 1,331,681 Enterprise Units (the “Unit Consideration”) and (2) a deemed contribution and increase in the capital account in Enterprise of Enterprise GP, the general partner of Enterprise and a wholly owned subsidiary of the TEPPCO GP Member, by an amount equal to the Additional Enterprise GP Interest (the “Deemed Capital Contribution” and, together with the Unit Consideration, the “TEPPCO GP Consideration”). “Additional Enterprise GP Interest” means the dollar amount, equal to 2/98ths of the aggregate fair market value of the Enterprise Units and Enterprise Class B Units issued in the Mergers as TEPPCO Consideration, Designated TEPPCO Unit Consideration and Unit Consideration, necessary to fund the capital contribution required to maintain Enterprise GP’s 2.0% Enterprise general partner interest.

Upon such exchange of the TEPPCO GP Member Interests and the recording of the name of the TEPPCO GP Member as a limited partner of Enterprise on the books and records of Enterprise, the TEPPCO GP Member shall automatically and effective as of the TEPPCO GP Effective Time be admitted to Enterprise as an Additional Limited Partner and be bound by the Enterprise Partnership Agreement as such. By its exchange of the TEPPCO GP Member Interests or by its acceptance of Enterprise Units, the TEPPCO GP Member confirms its agreement to be bound by all of the terms and conditions of the Enterprise Partnership Agreement, including the power of attorney granted in Section 2.6 thereof.

          (b) If, between the date of this Agreement and the TEPPCO GP Effective Time, there is a reclassification, recapitalization, split, split-up, unit distribution, combination or exchange of units with respect to, or rights issued in respect of, Enterprise Units, the Unit Consideration shall be adjusted accordingly to provide to the TEPPCO GP Member the same economic effect as contemplated by this Agreement prior to such event.

          (c) At the TEPPCO GP Effective Time, by virtue of the TEPPCO GP Merger and without any action on the part of the Enterprise Entities, all limited liability company interests in Enterprise Sub A issued and outstanding immediately prior to the TEPPCO GP Effective Time shall be converted into 100% of the limited liability company interests in the Surviving Entity, and, if permitted in the TEPPCO LLC Agreement, TEPPCO GP shall issue to Enterprise, as the holder of such limited liability company interests, a certificate evidencing such

limited liability company interests in the Surviving Entity. Enterprise agrees that at the TEPPCO GP Effective Time, Enterprise shall be automatically bound by the TEPPCO GP LLC Agreement, and Enterprise shall be admitted to the Surviving Entity as the sole member of the Surviving Entity immediately upon the TEPPCO GP Effective Time. At the TEPPCO GP Effective Time, the books and records of the Surviving Entity shall be revised to reflect the admission of Enterprise as the sole member of TEPPCO GP and the simultaneous withdrawal of any other members of TEPPCO GP, and TEPPCO GP shall automatically continue without dissolution.

When a reference is made in this Agreement to Articles, Sections, Exhibits or Schedules, such reference shall be to an Article or Section of or Exhibit or Schedule to this Agreement unless otherwise indicated. The table of contents and headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or

interpretation of this Agreement. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” No provision of this Agreement shall be construed to require Enterprise, Enterprise GP, TEPPCO, TEPPCO GP or any of their respective Subsidiaries or Affiliates to take or omit to take any action if doing so would violate any applicable obligation (arising in law or equity), rule or regulation.

     8.4 Counterparts. This Agreement may be executed in one or more counterparts, all of which shall be considered one and the same agreement and shall become effective when one or more counterparts have been signed by each of the parties and delivered to the other parties, it being understood that all parties need not sign the same counterpart.

     8.5 Entire Agreement; No Third Party Beneficiaries.

          (a) This Agreement, the Confidentiality Agreement, the Support Agreement and the exhibits and schedules hereto and the other agreements and instruments of the parties delivered in connection herewith constitute the entire agreement and supersede all prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof.

          (b) This Agreement shall be binding upon and inure solely to the benefit of each party hereto, and nothing in this Agreement, express or implied, is intended to or shall confer upon any other Person any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement. It is expressly understood and agreed that no TEPPCO employee or other Person shall have any rights or remedies (including any right of employment) under this Agreement.

          (c) The representations and warranties in this Agreement are the product of negotiations among the parties and are for the sole benefit of the parties. Any inaccuracies in such representations and warranties are subject to waiver by the parties hereto without notice or liability to any other Person. In some instances, the representations and warranties in this Agreement may represent an allocation among the parties of risks associated with particular matters regardless of knowledge of any of the parties. Consequently, Persons other than the parties may not rely upon the representations and warranties in this Agreement as characterizations of actual facts or circumstances as of the date of this Agreement or as of any other date.

     8.6 Governing Law. This Agreement shall be governed and construed in accordance with the laws of the State of Delaware applicable to contracts entered into and to be performed in the State of Delaware without giving effect to choice of law principles thereof.

     8.7 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any law or public policy, all other terms and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this

Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible.

     8.8 Assignment. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the parties hereto, in whole or in part (whether by operation of law or otherwise), without the prior written consent of the other parties, and any attempt to make any such assignment without such consent shall be null and void. Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of and be enforceable by the parties and their respective successors and assigns.

     8.9 Submission to Jurisdiction; Waivers. Each of the Enterprise Entities and the TEPPCO Entities irrevocably agrees that any legal action or proceeding with respect to this Agreement or for recognition and enforcement of any judgment in respect hereof brought by any party hereto or its successors or assigns may be brought and determined in the Chancery or other Courts of the State of Delaware, and each of the Enterprise Entities and the TEPPCO Entities hereby irrevocably submits with regard to any such action or proceeding for itself and in respect to its property, generally and unconditionally, to the exclusive jurisdiction of the aforesaid courts. Each of the Enterprise Entities and the TEPPCO Entities hereby irrevocably waives, and agrees not to assert, by way of motion, as a defense, counterclaim or otherwise, in any action or proceeding with respect to this Agreement, (a) any claim that it is not personally subject to the jurisdiction of the above-named courts for any reason other than the failure to lawfully serve process, (b) that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise), and (c) to the fullest extent permitted by applicable law, that (i) the suit, action or proceeding in any such court is brought in an inconvenient forum, (ii) the venue of such suit, action or proceeding is improper and (iii) this Agreement, or the subject matter hereof, may not be enforced in or by such courts.

     8.10 Waiver of Jury Trial. EACH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT AND ANY OF THE AGREEMENTS DELIVERED IN CONNECTION HEREWITH OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (A) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE EITHER OF SUCH WAIVERS, (B) IT UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF SUCH WAIVERS, (C) IT MAKES SUCH WAIVERS VOLUNTARILY, AND (D) IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 8.10.

     8.11 Enforcement. The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms. The parties further agree that money damages would not be a sufficient remedy

for any breach of this Agreement by the parties. Accordingly, it is agreed that the parties hereto shall be entitled, without the requirement of posting a bond or other security, to specific performance of the terms hereof, provided that such party is not in material default hereunder, this being in addition to any other remedy to which they are entitled at law or in equity.

     8.12 No Waiver Relating to Claims for Fraud/Willful Misconduct. The liability of any party under this Article 8 shall be in addition to, and not exclusive of, any other liability that such party may have at law or in equity based on such party’s (a) fraudulent acts or omissions or (b) willful misconduct. None of the provisions set forth in this Agreement shall be deemed to be a waiver by or release of any party of any right or remedy which such party may have at law or equity based on any other party’s fraudulent acts or omissions or willful misconduct nor shall any such provisions limit, or be deemed to limit, (i) the amounts of recovery sought or awarded in any such claim for fraud or willful misconduct, (ii) the time period during which a claim for fraud or willful misconduct may be brought, or (iii) the recourse which any such party may seek against another party with respect to a claim for fraud or willful misconduct.

     8.13 General Limitation of Damages. NOTWITHSTANDING ANY OTHER PROVISION OF THIS AGREEMENT TO THE CONTRARY, EXCEPT AS SET FORTH IN SECTION 8.12, THE ENTERPRISE ENTITIES SHALL NOT BE LIABLE TO THE TEPPCO ENTITIES, NOR SHALL THE TEPPCO ENTITIES BE LIABLE TO THE ENTERPRISE ENTITIES, FOR ANY EXEMPLARY, PUNITIVE, SPECIAL, INDIRECT, CONSEQUENTIAL, REMOTE OR SPECULATIVE DAMAGES (INCLUDING ANY DAMAGES ON ACCOUNT OF LOST PROFITS OR OPPORTUNITIES) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.
