20

and (6) of the receipt by the Partnership of any notification with respect to the suspension of the qualification of the Units for sale in any jurisdiction or the institution or threatening of any proceeding for such purpose.  The Partnership will use its best efforts to prevent the issuance of any such stop order or the suspension of any such qualification and, if issued, to obtain as soon as possible the withdrawal thereof.

(b)                                 Filing of Amendment or Supplement.    If, at any time when a prospectus relating to the Units is required to be delivered under the Securities Act, any event occurs as a result of which the Prospectus as then supplemented would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made not misleading, or if it shall be necessary to amend the Registration Statement or supplement the Prospectus to comply with the Securities Act or the Exchange Act or the respective rules thereunder, the Partnership promptly will (1) notify the Representatives of such event, (2) prepare and file with the Commission, subject to the second sentence of paragraph (a) of this Section 5, an amendment or supplement which will correct such statement or omission or effect such compliance and (3) supply any supplemented Prospectus to you in such quantities as you may reasonably request.

(f)                                    Qualification of Units.    The Partnership will arrange, if necessary, for the qualification of the Units for sale under the laws of such jurisdictions as the Representatives may designate, will maintain such qualifications in effect so long as required for the distribution of the Securities and will pay any fee of the NASD, in connection with its review of the offering; provided that in no event shall the Partnership

(c)                                  The Partnership shall have requested and caused (i) Fulbright & Jaworski L.L.P., counsel for the Partnership, to have furnished to the Representatives their opinion addressed to the Underwriters and dated the Closing Date, as set forth in Exhibit A and (ii) James C.

(i)                                     the representations and warranties of the Partnership in this Agreement are true and correct on and as of the Closing Date with the same effect as if made on the Closing Date and the Partnership has complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied at or prior to the Closing Date;

24

(ii)                                  no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or, to the Partnership knowledge, threatened; and

(iii)                               since the date of the most recent financial statements included or incorporated by reference in the Prospectus (exclusive of any supplement thereto), there has been no material adverse effect on the condition (financial or otherwise), prospects, earnings, business or properties of the Partnership and its subsidiaries, taken as a whole, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Prospectus (exclusive of any supplement thereto).

(j)                                     The NYSE shall have approved the Units for listing, subject only to official notice of issuance.

(k)                                  At the Execution Time, the Partnership shall have furnished to the Representatives a Lock-up Letter substantially in the form of Exhibit D hereto from each officer and director of the General Partner  addressed to the Representatives.

(l)                                     Prior to the Closing Date, the Partnership shall have furnished to the Underwriters such further information, certificates and documents as the Underwriters may reasonably request.

If any of the conditions specified in this Section 6 shall not have been fulfilled when and as provided in this Agreement, or if any of the opinions and certificates mentioned above or elsewhere in this Agreement shall not be reasonably satisfactory in form and substance to the Representatives and counsel for the Underwriters, this Agreement and all obligations of the Underwriters hereunder may be canceled at, or at any time prior to, the Closing Date by the Representatives.  Notice of such cancellation shall be given to the Partnership in writing or by telephone or facsimile confirmed in writing.

7.                                       Reimbursement of Underwriters’ Expenses.    If the sale of the Units provided for herein is not consummated because any condition to the obligations of the Underwriters set forth in Section 6 hereof is not satisfied, because of any termination pursuant to Section 10 hereof or because of any refusal, inability or failure on the part of the Partnership to perform any agreement herein or comply with any provision hereof other than by reason of a default by any of the Underwriters, the Partnership will reimburse the Underwriters through the Representatives on demand for all out-of-pocket expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by them in connection with the proposed purchase and sale of the Units.

8.                                       Indemnification and Contribution.    (a) The Partnership agrees to indemnify and hold harmless each Underwriter, the directors, officers, employees and agents of each Underwriter and each person who controls any Underwriter within the meaning of either the Securities Act or the Exchange Act against any and all losses, claims, damages or liabilities (including, but not limited to, the reasonable cost of investigation, legal representation and other expenses incurred in connection with, and any and all amounts paid in settlement of, any action, suit or proceeding between any of the indemnified parties and any indemnifying parties or between any indemnified party and any third party, or otherwise, or any claim asserted), joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement for the registration of the Units as originally filed or in any amendment thereof; (ii) any untrue statement or alleged untrue statement of a material fact contained in the Base Prospectus, any Preliminary Final Prospectus, or the Prospectus or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or the alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements, in the light in which they were made, not misleading; provided, however, that the Partnership will not

26

be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Partnership by or on behalf of any Underwriter through the Representatives specifically for inclusion therein; or (iii) any untrue statement or alleged untrue statement made by the Partnership in Section 1 hereof or the failure by the Partnership to perform when and as required any agreement or covenant contained herein, or (iii) any untrue statement or alleged untrue statement of any material fact contained in any audio or visual materials provided by the Partnership or based upon written information furnished by or with the consent of the Partnership including, without limitation, slides, videos, films or tape recordings used in connection with the marketing of the Units; provided, however, that the indemnity agreement contained in this subsection (a) with respect to any Preliminary Final Prospectus or Prospectus shall not inure to the benefit of any Underwriter (or to the benefit of any person controlling such Underwriter) from whom the person asserting any such loss, damage, expense, liability or claim purchased the Units which is the subject thereof if the Prospectus corrected any such alleged untrue statement or omission and if such Underwriter failed to send or give a copy of the Prospectus to such person at or prior to the written confirmation of the sale of such Units to such person, unless the failure is the result of noncompliance by the Partnership with paragraph (d) of Section 5 hereof. This indemnity agreement will be in addition to any liability which the Partnership may otherwise have.

The Partnership shall not be liable for any settlement of any claim, action, suit or proceeding effected without its written consent but if settled with the written consent of the General Partner, the Partnership agrees to indemnify and hold harmless any Underwriter and any such person from and against any loss or liability by reason of such settlement.  Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by subsection (c) below, then the indemnifying party agrees that it shall be liable for any settlement of any such claim, action, suit or proceeding effected without its written consent if (i) such settlement is entered into more than sixty (60) business days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement and (iii) such indemnified party shall have given the indemnifying party at least thirty (30) days’ prior notice of its intention to settle.  An indemnifying party will not, without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld, conditioned or delayed), settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and does not include an admission of fault, culpability or a failure to act, by or on behalf of such indemnified party.

(b)                                 Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Partnership, the directors of the General Partner, the respective officers of the General Partner who sign the Registration Statement, and each person who controls the Partnership within the meaning of either the Securities Act or the Exchange Act, and the successors and

27

assigns of the foregoing persons, to the same extent as the foregoing indemnity from the Partnership to each Underwriter, but only with reference to written information relating to such Underwriter furnished to the Partnership by or on behalf of such Underwriter through the Representatives specifically for inclusion in the documents referred to in the foregoing indemnity.  This indemnity agreement will be in addition to any liability which any Underwriter may otherwise have.  The Partnership acknowledges that the statements set forth in the last paragraph of the cover page regarding delivery of the Units and, under the heading “Underwriting”, (i) the list of Underwriters and their respective participation in the sale of the Units, (ii) the sentences related to concessions and reallowances and (iii) the paragraphs related to stabilization, syndicate covering transactions and penalty bids in any Preliminary Final Prospectus and the Prospectus constitute the only information furnished in writing by or on behalf of the several Underwriters for inclusion in any Preliminary Final Prospectus or the Prospectus.

No Underwriter shall be liable for any settlement of any claim, action, suit or proceeding effected without the written consent of such Underwriter but if settled with the written consent of such Underwriter, such Underwriter agrees to indemnify and hold harmless the Partnership and any such person from and against any loss or liability by reason of such settlement.  Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated in subsection (c) below, then the indemnifying party agrees that it shall be liable for any settlement of any such claim, action, suit or proceeding effected without its written consent if (i) such settlement is entered into more than sixty (60) business days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement and (iii) such indemnified party shall have given the indemnifying party at least thirty (30) days’ prior notice of its intention to settle.  An indemnifying party will not, without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld, conditioned or delayed), settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and does not include an admission of fault, culpability or a failure to act, by or on behalf of such indemnified party.

(c)                                  Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above.  The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party

28

shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party.  Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ one separate counsel (in addition to local counsel), and the indemnifying party shall bear the fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party.

(d)                                 In the event that the indemnity provided in paragraph (a) or (b) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Partnership and the Underwriters severally agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively “Losses”) to which the Partnership and one or more of the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Partnership on the one hand and by the Underwriters on the other from the offering of the Units; provided, however, that in no case shall any Underwriter (except as may be provided in any agreement among underwriters relating to the offering of the Units) be responsible for any amount in excess of the underwriting discount or commission applicable to the Units purchased by such Underwriter hereunder.  If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Partnership and the Underwriters severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Partnership on the one hand and of the Underwriters on the other in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations.  Benefits received by the Partnership shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by it, and benefits received by the Underwriters shall be deemed to be equal to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth on the cover page of the Prospectus.  Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Partnership on the one hand or the Underwriters on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission.  The Partnership and the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above.  Notwithstanding the provisions of this paragraph (d), 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 was not guilty of such fraudulent misrepresentation.  For

29

purposes of this Section 8, each person who controls an Underwriter within the meaning of either the Securities Act or the Exchange Act and each director, officer, employee and agent of an Underwriter shall have the same rights to contribution as such Underwriter, and each person who controls the Partnership within the meaning of either the Securities Act or the Exchange Act, each officer of the General Partner who shall have signed the Registration Statement and each director of the General Partner shall have the same rights to contribution as the Partnership, subject in each case to the applicable terms and conditions of this paragraph (d).

9.                                       Default by an Underwriter.    If any one or more Underwriters shall fail to purchase and pay for any of the Units agreed to be purchased by such Underwriter or Underwriters hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the number of Units set forth opposite their names in Schedule I hereto bears to the aggregate number of Units set forth opposite the names of all the remaining Underwriters) the Units which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, however, that in the event that the aggregate number of Units which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate number of Units set forth in Schedule I hereto, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Units, and if such nondefaulting Underwriters do not purchase all the Units, this Agreement will terminate without liability to any nondefaulting Underwriter or the Partnership.  In the event of a default by any Underwriter as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding five Business Days, as the Representatives shall determine in order that the required changes in the Registration Statement and the Prospectus or in any other documents or arrangements may be effected.  Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Partnership and any nondefaulting Underwriter for damages occasioned by its default hereunder.

10.                                 Termination.    This Agreement shall be subject to termination in the absolute discretion of the Representatives, by notice given to the Partnership prior to delivery of and payment for the Units, if (x) since the Execution Time or the earlier respective dates as of which information is given in the Registration Statement and the Prospectus, there has been any material adverse change in the business, properties, management, financial condition or results of operations of the TEPPCO Entities or their subsidiaries taken as a whole, which would, in your judgment or in the judgment of such group of Underwriters, make it impracticable or inadvisable to market the Units on the terms and in the manner contemplated in the Registration Statement and the Prospectus or (y) since the Execution Time: (i) trading in the Partnership’s Common Units shall have been suspended by the Commission or the NYSE or limited or minimum prices shall have been established in respect of the Partnership’s Common Units on any such Exchange, (ii) trading in securities generally on the NYSE shall have been suspended or limited or minimum prices shall have been established on such Exchange, (iii) a banking moratorium shall have been declared either by Federal or New York State authorities or (iv) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war, or other calamity or crisis the effect of which on financial markets is such as to make it, in the judgment of the Representatives, impractical or inadvisable to proceed with the offering or delivery of the Units as contemplated by the Prospectus (exclusive of any supplement thereto), or (z) since the Execution Time, there shall have occurred any downgrading, or any

30

notice or announcement shall have been given or made of (i) any intended or potential downgrading or (ii) any watch, review or possible change that does not indicate an affirmation or improvement in the rating accorded any securities of or guaranteed by the Partnership or any of its subsidiaries by any “nationally recognized statistical rating organization,” as that term is defined in Rule 436(g)(2) under the Securities Act.

11.                                 Representations and Indemnities to Survive.    The respective agreements, representations, warranties, indemnities and other statements of the Partnership or the General Partner’s respective officers and of the Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or the Partnership or any of the General Partner’s respective officers, directors, employees, agents or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the Units.  The provisions of Sections 7 and 8 hereof shall survive the termination or cancellation of this Agreement.

13.                                 Successors.    This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers, directors, employees, agents and controlling persons referred to in Section 8 hereof, and no other person will have any right or obligation hereunder.

14.                                 Applicable Law.    This Agreement will be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed within the State of New York.
