          3.1 Effect of the Merger on Equity Securities.

          (a) At the TEPPCO Effective Time, by virtue of the TEPPCO Merger and without any action on the part of any holder of any TEPPCO Units:

               (i) All TEPPCO Units that are TEPPCO GP Owned Units immediately prior to the TEPPCO Effective Time shall cease to be outstanding and shall be canceled and retired and shall cease to exist, and any certificates representing any such TEPPCO GP Owned Units shall be surrendered for cancellation; provided, however, for purposes of clarification, TEPPCO GP shall continue to hold general partner interests in TEPPCO and continue as the general partner of TEPPCO.

               (ii) Subject to Sections 3.1(a)(i), 3.1(a)(iii), 3.1(b) and 3.7, each TEPPCO Unit issued and outstanding immediately prior to the TEPPCO Effective Time shall be converted into the right to receive 1.24 Enterprise Units (the “ Exchange Ratio ,” and such amount of Enterprise Units, the “ TEPPCO Consideration ”). Each TEPPCO Unit converted into the right to receive the TEPPCO Consideration pursuant to this Section 3.1(a)(ii) shall cease to be outstanding and shall be canceled and retired and shall cease to exist, and each holder of a TEPPCO Unit immediately prior to the TEPPCO Effective Time (whether certificated or non-certificated and represented in book-entry form) shall thereafter cease to be a limited partner of TEPPCO or have any rights with respect to such TEPPCO Units, except the right to be admitted as an Additional Limited Partner and receive the Enterprise Units to be issued in consideration therefor and any distributions to which holders of TEPPCO Units become entitled all in accordance with this Article 3 upon the surrender of (x) a certificate that immediately prior to the TEPPCO Effective Time represented TEPPCO Units (“ TEPPCO Certificate ”) or (y) non-certificated TEPPCO Units represented in book-entry form (“ Book Entry TEPPCO Units ”). Enterprise GP consents to the admission of each TEPPCO Unitholder as an Additional Limited Partner who is issued Enterprise Units in exchange for such TEPPCO Unitholder’s TEPPCO Units in accordance with this Article 3 upon the proper surrender of the TEPPCO Certificate or

Book Entry TEPPCO Unit representing such TEPPCO Units. Upon such surrender of the TEPPCO Certificate or the Book Entry TEPPCO Unit (or upon a waiver of the requirement to surrender a TEPPCO Certificate granted by Enterprise GP in its sole discretion) and the recording of the name of such Person as a limited partner of Enterprise in respect of the applicable amount of Enterprise Units on the books and records of Enterprise, such Person shall automatically and effective as of the TEPPCO Effective Time be admitted to Enterprise as an Additional Limited Partner in respect of the applicable amount of Enterprise Units and be bound by the Enterprise Partnership Agreement as such. By its surrender of a TEPPCO Certificate or a Book Entry TEPPCO Unit, or by its acceptance of Enterprise Units, a TEPPCO Unitholder 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.

               (iii) In lieu of the TEPPCO Consideration set forth in Section 3.1(a)(ii), and as consented to by DFI pursuant to the Support Agreement, with respect to 3,645,509 TEPPCO Units owned by DFI (the “ Designated TEPPCO Units ,” but excluding, for the avoidance of doubt, any additional TEPPCO Units owned by DFI), each Designated TEPPCO Unit issued and outstanding immediately prior to the TEPPCO Effective Time shall be converted into the right to receive 1.24 Enterprise Class B Units (the “ Designated TEPPCO Unit Exchange Ratio ,” and such number of Enterprise Class B Units, the “ Designated TEPPCO Unit Consideration ”). Each Designated TEPPCO Unit converted into the right to receive the Designated TEPPCO Unit Consideration pursuant to this Section 3.1(a)(iii) shall cease to be outstanding and shall be canceled and retired and shall cease to exist, and DFI shall thereafter cease to be a limited partner of TEPPCO or have any rights with respect to such Designated TEPPCO Units, except the right to be admitted as an Additional Limited Partner and receive the Enterprise Class B Units to be issued in consideration therefor. Enterprise GP consents to the admission of DFI as an Additional Limited Partner who is issued Enterprise Class B Units in exchange for the Designated TEPPCO Units in accordance with this Article 3 upon the proper surrender of the TEPPCO Certificate or Book Entry TEPPCO Unit representing the Designated TEPPCO Units. Upon such surrender of the TEPPCO Certificate or Book Entry TEPPCO Unit representing Designated TEPPCO Units (or upon a waiver of the requirement to surrender a TEPPCO Certificate granted by Enterprise GP in its sole discretion) and the recording of the name of DFI as a limited partner of Enterprise in respect of the applicable amount of Enterprise Class B Units on the books and records of Enterprise, DFI shall automatically and effective as of the TEPPCO Effective Time be admitted to Enterprise as an Additional Limited Partner in respect of the applicable amount of Enterprise Class B Units and be bound by the Enterprise Partnership Agreement as such. By its surrender of a TEPPCO Certificate or Book Entry TEPPCO Unit, or by its acceptance of Enterprise Class B Units, DFI 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 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 or the TEPPCO Units, the Exchange Ratio and the Designated TEPPCO Unit Exchange Ratio shall be adjusted accordingly to provide to the holders of TEPPCO Units and the Designated TEPPCO Units the same economic effect as contemplated by this Agreement prior to such event.

          (c) At the TEPPCO Effective Time, by virtue of the TEPPCO Merger and without any action on the part of the Enterprise Entities, the outstanding limited liability company interests in Enterprise Sub B issued and outstanding immediately prior to the TEPPCO Effective Time shall be converted into 100% of the limited partner interests in the Surviving Partnership, and TEPPCO shall issue to Enterprise, as the holder of such limited partner interests, a certificate evidencing units representing such limited partner interests in the Surviving Partnership. Enterprise agrees that at the TEPPCO Effective Time, Enterprise shall be automatically bound by the TEPPCO Partnership Agreement, and Enterprise shall be admitted to the Surviving Partnership as the sole limited partner of the Surviving Partnership immediately upon the TEPPCO Effective Time. At the TEPPCO Effective Time, the books and records of the Surviving Partnership shall be revised to reflect the admission of Enterprise as the sole limited partner of the Surviving Partnership and the simultaneous withdrawal of all other limited partners of TEPPCO, and TEPPCO shall automatically continue without dissolution.

Promptly after the TEPPCO Effective Time, Enterprise will provide each holder of TEPPCO Options with a notice describing the assumption and conversion of such awards.

Each grant of phantom units of Enterprise in respect of which a TEPPCO Phantom Unit was so assumed and converted shall be subject to, and shall vest upon, the terms and conditions that are equivalent to those of the applicable TEPPCO Phantom Unit. Promptly after the TEPPCO Effective Time, Enterprise will provide each holder of TEPPCO Phantom Units with a notice describing the assumption and conversion of such awards. The assumption of the TEPPCO Phantom Units pursuant to this Section 3.2(c) shall be in full satisfaction of the obligations in respect thereof.

At the TEPPCO Effective Time, automatically and without any action on the part of the holder thereof, each outstanding Unit Appreciation Right (“ TEPPCO UAR ”) granted to a TEPPCO Employee pursuant to the TEPPCO Unit Plans shall be assumed by Enterprise and converted into (i) a number of Common Unit Appreciation Rights (“ CUARs ”) of Enterprise equal to the product of the number of TEPPCO UARs to which such grant was subject at the time of such assumption multiplied by the Exchange Ratio, and (ii) with an exercise price per CUAR equal to the per TEPPCO UAR exercise price divided by the Exchange Ratio (with any resulting exercise price that contains a fraction of a cent being increased to the next whole cent). Each CUAR of Enterprise shall be subject to, and vest upon, the terms and conditions that are equivalent to those applicable to the TEPPCO UARs; provided however , that the new “Grant DER per Unit” (as defined in the award agreement for the applicable TEPPCO UAR) that shall apply to the CUAR of Enterprise shall be (i) the most recent quarterly distribution paid (or with respect to a more recent record date prior to the TEPPCO Effective Time, the most recent unpaid distribution declared) with respect to an Enterprise Unit minus (ii) (A) the difference between (x) the most recent quarterly distribution paid (or with respect to a more recent record date prior to the TEPPCO Effective Time, the most recent unpaid distribution declared) with respect to a TEPPCO Unit and (y) the Grant DER per Unit on the date of grant of such TEPPCO UAR, divided by (B) the Exchange Ratio.

Any fractional Distribution Equivalent Right of Enterprise shall be rounded up

to the nearest whole Distribution Equivalent Right of Enterprise. Each Distribution Equivalent Right of Enterprise shall be subject to terms and conditions that are equivalent to those applicable to the TEPPCO DERs; provided, however, that the cash distributions paid with respect to Distribution Equivalent Rights of Enterprise will be equal to the cash distributions paid on the Enterprise Units.

          3.4 Exchange Procedures . Promptly after the TEPPCO Effective Time, Enterprise shall cause the Exchange Agent to mail to each applicable holder of a TEPPCO Certificate or Book Entry TEPPCO Unit (other than those representing Designated TEPPCO Units) (a) a letter of transmittal (the “ Letter of Transmittal ”) that shall specify that delivery shall be effected, and risk of loss and title to the TEPPCO Certificate or Book Entry TEPPCO Units shall pass, only upon proper delivery of the TEPPCO Certificate or Book Entry TEPPCO Units to the Exchange Agent, and which Letter of Transmittal shall be in customary form and have such other provisions as may be necessary for the applicable TEPPCO Unitholders to be admitted as Additional Limited Partners and other provisions as Enterprise and TEPPCO may reasonably specify (such letter to be reasonably acceptable to Enterprise and TEPPCO prior to the Effective Time) and (b) instructions for effecting the surrender of such TEPPCO Certificate or Book Entry TEPPCO Units in exchange for the TEPPCO Consideration, together with any distributions with respect thereto and any cash in lieu of fractional units. Upon surrender of a TEPPCO Certificate or Book Entry TEPPCO Unit to the Exchange Agent together with the relevant Letter of Transmittal, duly executed and completed in accordance with the instructions thereto, and such other documents as may reasonably be required by the Exchange Agent, the holder of such TEPPCO Certificate or Book Entry TEPPCO Unit shall be entitled to receive in exchange therefor (A) Enterprise Units representing, in the aggregate, the whole number of Enterprise Units that such holder has the right to receive pursuant to Section 3.1(a) (in each case, after taking into account all TEPPCO Units then held by such holder), and (B) a check in the amount equal to the cash, if any, that such holder has the right to receive pursuant to Sections 3.5 and 3.7. No interest will be paid or will accrue on any cash payable pursuant to the provisions of this Article 3.

          3.5 Distributions with Respect to Unexchanged TEPPCO Units . No distributions with a record date after the TEPPCO Effective Time shall be paid to the holder of any TEPPCO Certificate or Book Entry TEPPCO Unit with respect to the Enterprise Units that such holder would be entitled to receive upon surrender of such TEPPCO Certificate or Book Entry TEPPCO Unit, and no cash payment in lieu of fractional Enterprise Units shall be paid to any such holder pursuant to Section 3.7, until such holder shall surrender such TEPPCO Certificate or Book Entry TEPPCO Unit in accordance with Section 3.4. Subject to the effect of applicable laws, following the later of the surrender of any such TEPPCO Certificate or Book Entry TEPPCO Unit and the TEPPCO Effective Time, there shall be paid to the record holder thereof without interest (a) promptly after such time, the amount of any cash payable in lieu of fractional Enterprise Units to which such holder is entitled pursuant to Section 3.7 and the amount of any distributions with a record date after the TEPPCO Effective Time theretofore paid with respect to such whole Enterprise Units and (b) at the appropriate payment date, the amount of distributions with a record date after the TEPPCO Effective Time and a payment date subsequent thereto and to such surrender payable with respect to such Enterprise Units.

          3.6 No Further Ownership Rights in TEPPCO Units . All Enterprise Units issued and cash paid upon conversion of TEPPCO Units in accordance with the terms of this Article 3 (including any cash paid pursuant to Section 3.5 or 3.7) shall be deemed to have been issued or paid in full satisfaction of all rights pertaining to the TEPPCO Units.

          3.7 No Fractional Enterprise Units . No certificates or scrip or Enterprise Units representing fractional Enterprise Units or book-entry credit of the same shall be issued upon the surrender for exchange of TEPPCO Certificate or Book Entry TEPPCO Units, and such fractional unit interests will not entitle the owner thereof to vote or to have any rights of a holder of Enterprise Units in respect thereof. In lieu of any such fractional Enterprise Unit, each holder of TEPPCO Units who would otherwise have been entitled to a fraction of an Enterprise Unit upon surrender of TEPPCO Certificate or Book Entry TEPPCO Units (determined after taking into account all TEPPCO Units delivered by such holder) shall be paid upon such surrender cash (without interest) in an amount equal to the value (determined with reference to the Average Closing Price as of the Closing Date) of such fractional unit interest. Such payment with respect to fractional units is merely intended to provide a mechanical rounding off of, and is not a separately bargained for, consideration.

          3.8 Termination of Exchange Fund . Any portion of the Exchange Fund that remains undistributed to the holders of the applicable TEPPCO Certificates or Book Entry TEPPCO Units 12 months after the TEPPCO Effective Time shall, at Enterprise’s request, be delivered to Enterprise or otherwise on the instruction of Enterprise, and any holders of the applicable TEPPCO Certificate or Book Entry TEPPCO Units who have not theretofore complied with this Article 3 shall after such delivery look only to Enterprise for any amounts payable to such holders pursuant to this Article 3. Any such portion of the Exchange Fund remaining unclaimed by holders of the applicable TEPPCO Units immediately prior to such time as such amounts would otherwise escheat to or become property of any Governmental Entity shall, to the extent permitted by law, become the property of Enterprise free and clear of any claims or interest of any Person previously entitled thereto.

          3.9 No Liability . To the fullest extent permitted by law, none of the Enterprise Entities, the TEPPCO Entities or the Exchange Agent shall be liable to any Person in respect of any portion of the Exchange Fund required to be delivered to a public official pursuant to any applicable abandoned property, escheat or similar law.

          3.10 Investment of the Exchange Fund . The Exchange Agent shall invest any cash included in the Exchange Fund as directed by Enterprise on a daily basis; provided that any investment of such Exchange Fund shall be limited to direct short-term obligations of, or short-term obligations fully guaranteed as to principal and interest by, the U.S. government and that no such investment or loss thereon shall affect the amounts payable or the timing of the amounts payable to TEPPCO Unitholders pursuant to the other provisions of this Article 3. Any interest and other income resulting from such investments shall promptly be paid to Enterprise.

          3.11 Unregistered Certificates . In the event of a transfer of ownership of TEPPCO Units that is not registered in the unit transfer register of TEPPCO, Enterprise Units to be issued upon due surrender of the TEPPCO Certificate or Book Entry TEPPCO Unit may be issued to such transferee if the TEPPCO Certificate or Book Entry TEPPCO Unit is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and to evidence that any applicable unit transfer or other Taxes have been paid or are not applicable.

          3.12 Lost Certificates . If any TEPPCO Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such certificate to be lost, stolen or destroyed and, if required by Enterprise, the posting by such Person of a bond in such reasonable amount as Enterprise may direct as indemnity against any claim that may be made against it with respect to such certificate, following the TEPPCO Effective Time, as the case may be, the Exchange Agent will deliver in exchange for such lost, stolen or destroyed certificate the consideration and amounts payable with respect to the TEPPCO Units formerly represented thereby pursuant to this Article 3.

          3.13 Withholding Rights . Enterprise shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code and the rules and regulations promulgated thereunder, or any provision of state, local or foreign Tax law. To the extent that amounts are so withheld or paid over to or deposited with the relevant Governmental Entity by Enterprise, such amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction and withholding was made by Enterprise.

          3.14 Further Assurances . At and after the TEPPCO Effective Time, the officers and directors of the Surviving Partnership or the Surviving Partnership’s general partner shall be authorized to execute and deliver, in the name and on behalf of the Surviving Partnership (or in the name and on behalf of the Surviving Partnership’s general partner, on behalf of the Surviving Partnership, as the case may be), any deeds, bills of sale, assignments or assurances and to take and do, in the name and on behalf of the Surviving Partnership (or in the name and on behalf of the Surviving Partnership’s general partner, on behalf of the Surviving Partnership, as the case may be), any other actions and things necessary to vest, perfect or confirm of record or otherwise in the Surviving Partnership any and all right, title and interest in, to and under any of the rights, properties or assets acquired or to be acquired by the Surviving Partnership as a result of, or in connection with, the TEPPCO Merger.

          3.15 Unit Transfer Books . Subject to Section 3.1(c), the unit transfer books of TEPPCO shall be closed immediately upon the TEPPCO Effective Time, and there shall be no further registration of transfers of TEPPCO Units thereafter on the records of TEPPCO. On or after the TEPPCO Effective Time, any TEPPCO Certificate or Book Entry TEPPCO Units presented to the Exchange Agent, Enterprise or the Surviving Partnership for any reason (other than, for purposes of clarification, any certificates issued pursuant to Section 3.1(c)) shall be converted into the right to receive the TEPPCO Consideration with respect to the TEPPCO Units formerly represented thereby (including any cash in lieu of fractional Enterprise Units to which the holders thereof are entitled pursuant to Section 3.7 and any distributions to which the holders thereof are entitled pursuant to Section 3.5).

Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” The meanings given to terms defined herein shall be equally applicable to both the singular and plural forms of such terms. The headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. This Agreement is the product of negotiation by the parties having the assistance of counsel and other advisers. It

is the intention of the parties that this Agreement not be construed more strictly with regard to one party than with regard to the others.

      6.6 Counterparts.

      6.7 Entire Agreement. This Agreement and, solely to the extent of the defined terms referenced herein, the Merger Agreements, together with the schedule annexed hereto, embody the complete agreement and understanding among the parties hereto with respect to the subject matter hereof and supersede and preempt any prior understandings, agreements or representations by or among the parties, written and oral, that may have related to the subject matter hereof in any way.

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 6.8.

Each party may waive any right of such party hereunder by an instrument in writing signed by such party and delivered to the Partnership and the Unitholders.

      6.10 Remedies.

           (a) Each party hereto acknowledges that monetary damages would not be an adequate remedy in the event that any covenant or agreement in this Agreement is not performed in accordance with its terms, and it is therefore agreed that, in addition to and without limiting any other remedy or right it may have, the non-breaching party will have the right to an injunction, temporary restraining order or other equitable relief in any court of competent jurisdiction enjoining any such breach and enforcing specifically the terms and provisions

hereof. Each party hereto agrees not to oppose the granting of such relief in the event a court determines that such a breach has occurred, and to waive any requirement for the securing or posting of any bond in connection with such remedy.

      6.11 Severability. Any term or provision of this Agreement which is determined by a court of competent jurisdiction to be invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement or affecting the validity or enforceability of any of the terms or provisions of this Agreement in any other jurisdiction, and if any provision of this Agreement is determined to be so broad as to be unenforceable, the provision shall be interpreted to be only so broad as is enforceable, in all cases so long as neither the economic nor legal substance of the transactions contemplated hereby is affected in any manner adverse to any party or its equityholders. Upon any such determination, the parties shall negotiate in good faith in an effort to agree upon a suitable and equitable substitute provision to effect the original intent of the parties as closely as possible and to the end that the transactions contemplated hereby shall be fulfilled to the maximum extent possible.

      6.12 Successors and Assigns; Third Party Beneficiaries. Neither this Agreement nor any of the rights or obligations of any party under this Agreement shall be assigned, in whole or in part (by operation of law or otherwise), by any party without the prior written consent of the other parties hereto. Subject to the foregoing, this Agreement shall bind and inure to the benefit of and be enforceable by the parties hereto and their respective successors and permitted assigns. Nothing in this Agreement, express or implied, is intended to confer on any Person other than the parties hereto or the parties’ respective successors and permitted assigns any rights, remedies, obligations or liabilities under or by reason of this Agreement.

          “ Outstanding ” means, with respect to Partnership Securities, all Partnership Securities that are issued by the Partnership and reflected as outstanding on the Partnership’s books and records as of the date of determination; provided , however , that with respect to Partnership Securities, if at any time any Person or Group (other than the General Partner or its Affiliates) beneficially owns 20% or more of any Outstanding Partnership Securities of any class then Outstanding, all Partnership Securities owned by such Person or Group shall not be voted on any matter and shall not be considered to be Outstanding when sending notices of a meeting of Limited Partners to vote on any matter (unless otherwise required by law), calculating required votes, determining the presence of a quorum or for other similar purposes under this Agreement, except that Common Units so owned shall be considered to be Outstanding for purposes of Section 11.1(b)(iv) (such Common Units shall not, however, be treated as a separate class of Partnership Securities for purposes of this Agreement); provided, further , that the limitation in the foregoing proviso shall not apply (i) to any Person or Group who acquired 20% or more of any Outstanding Partnership Securities of any class then Outstanding directly from the General Partner or its Affiliates, (ii) to any Person or Group who acquired 20% or more of any Outstanding Partnership Securities of any class then Outstanding directly or indirectly from a Person or Group described in clause (i) if the General Partner shall have notified such Person or Group in writing, prior to such acquisition, that such limitation shall not apply to such Person or Group or (iii) to any Person or Group who acquired 20% or more of any Partnership Securities issued by the Partnership with the prior approval of the Board of Directors of the General Partner; and provided , further , that none of the Class B Units shall be deemed to be Outstanding for purposes of determining if any Class B Units are entitled to distributions of Available Cash unless such Class B Units shall have been reflected on the books of the Partnership as

outstanding during such Quarter and on the Record Date for the determination of any distribution of Available Cash.

          (b) Article IV; Section 4.7(d) . Article IV of the Partnership Agreement is hereby amended to add Section 4.7(d) as follows:

     “(d) The transfer of a Class B Unit that has converted into a Common Unit shall be subject to the restrictions imposed by Section 6.9.”

          (c) Section 5.5(c). Section 5.5(c) of the Partnership Agreement is hereby amended and restated as follows:

     “(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) Subject to Section 6.9, immediately prior to the transfer of a Class B Unit or of a Class B Unit that has converted into a Common Unit pursuant to Section 5.12(f) by a holder thereof (other than a transfer to an Affiliate unless the General Partner elects to have this subparagraph 5.5(c)(ii) apply), the Capital Account maintained for such Person with respect to its Class B Units or converted Class B Units will (A) first , be allocated to the Class B Units or converted Class B Units to be transferred in an amount equal to the product of (x) the number of such Class B Units or converted Class B Units to be transferred and (y) the Per Unit Capital Amount for a Common Unit, and (B) second , any remaining balance in such Capital Account will be retained by the transferor, regardless of whether it has retained any Class B Units or converted Class B Units. Following any such allocation, the transferor’s Capital Account, if any, maintained with respect to the retained Class B Units or retained converted Class B Units, if any, will have a balance equal to the amount allocated under clause (B) hereinabove, and the transferee’s Capital Account established with respect to the transferred Class B Units or converted Class B Units will have a balance equal to the amount allocated under clause (A) hereinabove.”

          (d) Article V; Section 5.12 . Article V of the Partnership Agreement is hereby amended to add a new Section 5.12 creating a new series of Partnership Units as follows:

               “Section 5.12 Establishment of Class B Units .

     (a) General . The General Partner hereby designates and creates a class of Units to be designated as “Class B Units” and consisting of a total of 4,520,431 Class B Units, and fixes the designations, preferences and relative, participating, optional or other special rights, powers and duties of holders of the Class B Units as set forth in this Section 5.12.

     (b) Rights of Class B Units . During the period commencing upon issuance of the Class B Units and ending on the Class B Conversion Effective Date:

     (i) Allocations . Except as otherwise provided in this Agreement, all items of Partnership income, gain, loss, deduction and

credit, including Unrealized Gain or Unrealized Loss to be allocated to the Partners pursuant to Section 6.1(c), shall be allocated to the Class B Units to the same extent as such items would be so allocated if such Class B Units were Common Units that were then Outstanding.

     (ii) Distributions . Prior to the Class B Conversion Effective Date, the Class B Units shall not be entitled to receive distributions of Available Cash pursuant to Section 6.3.

     (c) Voting Rights . Prior to the Class B Conversion Effective Date, the Class B Units shall be entitled to vote with the Common Units as a single class on any matters on which Common Unitholders are entitled to vote, except that the Class B Units shall be entitled to vote as a separate class on any matter that adversely affects the rights or preferences of the Class B Units in relation to other classes of Partnership Interests (including as a result of a merger or consolidation) or as required by law. The approval of a majority of the Class B Units shall be required to approve any matter for which the holders of the Class B Units are entitled to vote as a separate class. Each Class B Unit will be entitled to the number of votes equal to the number of Common Units into which a Class B Unit is convertible at the time of the record date for the vote or written consent on the matter.

     (d) Certificates . The Class B Units will be evidenced by certificates in substantially the form of Exhibit A to this Amendment No. 4 and, subject to the satisfaction of any applicable legal and regulatory requirements, may be assigned or transferred in a manner identical to the assignment and transfer of other Units. The certificates will initially include a restrictive legend to the effect that the Class B Units have not been registered under the Securities Act or any state securities laws.

     (e) Registrar and Transfer Agent . The General Partner will act as registrar and transfer agent of the Class B Units.

     (f) Conversion . Each Class B Unit shall automatically convert into one Common Unit (subject to appropriate adjustment pursuant to Section 5.10 in the event of any split-up, combination or similar event affecting the Common Units or other Units that occurs prior to the Class B Conversion Effective Date) on the date immediately following the payment date for the 16th distribution of Available Cash pursuant to Section 6.3 following the Closing Date (as defined in the Merger Agreement”) (the “ Class B Conversion Effective Date ”) without any further action by the holders thereof. The terms of the Class B Units will be changed, automatically and without further action, on the Class B Conversion Effective Date so that each Class B Unit is converted into one Common Unit and, immediately thereafter, none of the Class B Units shall be Outstanding; provided, however , that such converted Class B Units will remain subject to the provisions of Sections 6.1(d)(xiii) and 6.9.

     (g) Surrender of Certificates . Subject to the requirements of Section 6.9, on or after the Class B Conversion Effective Date, each holder of Class B Units shall promptly surrender the Class B Unit Certificates therefor, duly endorsed, at the office of the General Partner or of any transfer agent for the Class B Units. In the case of any such conversion, the Partnership shall, as soon as practicable thereafter, issue and deliver at such office to such holder of Class B Units one or more Unit Certificates, registered in the name of such holder, or other evidence of the issuance of uncertificated certificates, for the number of Common Units to which such holder shall be entitled. Such conversion shall be deemed to have been made as of the Class B Conversion Effective Date whether or not the Class B Unit Certificate has been surrendered as of such date, and the Person entitled to receive the Common Units issuable upon such conversion shall be treated for all purposes as the record holder of such Common Units as of such date.

     (e)  Section 6. 1(d)(iii) (A) . Section 6.1(d)(iii)(A) of the Partnership Agreement is hereby amended and restated to read in its entirety:

     “A. 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 Unitholder with respect to its Units for a taxable year is greater (on a per Unit basis) than the amount of cash or the Net Agreed Value of property distributed to the other Unitholders (except Unitholders holding Class B Units with respect to any Record Date prior to the Class B Conversion Effective Date) with respect to their Units (on a per Unit basis), then (1) there shall be allocated income and gain to each Unitholder receiving such greater cash or property distribution until the aggregate amount of such items allocated pursuant to this Section 6.1(d)(iii)(A) for the current taxable year and all previous taxable years is equal to the product of (aa) 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 receiving the smallest distribution and (bb) the number of Units owned by the Unitholder receiving the greater distribution; and (2) the General Partner shall be allocated income and gain in an aggregate amount equal to the product obtained by multiplying the sum of the amounts allocated in clause (1) above by the quotient obtained by dividing the General Partner’s Percentage Interest by the aggregate Percentage Interest of Partners other than the General Partner.

     (f)  Section 6. 1(d)(xiii) . Section 6.1(d) is hereby amended and restated to add a new Section 6.1(d)(xiii) as follows:

     “(xiii) Economic Uniformity . With respect to any taxable period in which the Class B Conversion Effective Date occurs (and, if necessary, any subsequent taxable period), items of Partnership gross income, gain, deduction or loss for the taxable period shall be allocated 100% to each Limited Partner with respect to such Limited Partner’s Class B Units that are Outstanding on the Class B Conversion Effective Date in the proportion that the respective number of Class B Units held by such Partner bears to the total number of Class B Units then Outstanding, until each such Partner has been

allocated the amount of gross income, gain, deduction or loss with respect to such Partner’s Class B Units that causes the Capital Account attributable to each Class B Unit, on a per Unit basis, to equal the Per Unit Capital Amount for a Common Unit on the Class B Conversion Effective Date. The purpose for this allocation is to establish uniformity between the Capital Accounts underlying converted Class B Units and the Capital Accounts underlying Common Units immediately prior to the conversion of Class B Units into Common Units.

     (g)  Article VI; Section 6.9 . Article VI is hereby amended and restated to add a new Section 6.9 as follows:

     “Section 6.9 Special Provisions Relating to the Holders of Class B Units . A Unitholder holding a Class B Unit that has converted into a Common Unit pursuant to Section 5.12 shall not be issued a Unit Certificate pursuant to Section 4.1, and shall not be permitted to transfer such Common Units until such time as the General Partner determines, based on advice of counsel, that the converted Class B Unit should have, as a substantive matter, like intrinsic economic and federal income tax characteristics of an Initial Common Unit. In connection with the condition imposed by this Section 6.9, the General Partner shall take whatever steps are required to provide economic uniformity to the converted Class B Units in preparation for a transfer of such Common Units, including the application of Sections 5.5(c)(ii) and 6.1(d)(xiii); provided , however , that no such steps may be taken that would have a material adverse effect on the Unitholders holding Common Units represented by Unit Certificates.”

     Section 2. Ratification of Partnership Agreement . Except as expressly modified and amended herein, all of the terms and conditions of the Partnership Agreement shall remain in full force and effect.

     Section 3. Governing Law . This Amendment No. 4 will be governed by and construed in accordance with the laws of the State of Delaware.

     Section 4. Counterparts . This Amendment No. 4 may be executed in counterparts, all of which together shall constitute an agreement binding on all the parties hereto, notwithstanding that all such parties are not signatories to the original or the same counterpart.

     IN WITNESS WHEREOF, this Amendment No. 4 has been executed as of the date first written above.

          (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.

     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.
