The several obligations of the Underwriters hereunder are subject to the accuracy of the representations and warranties on the part of the TEPPCO Entities on the date hereof and at the time of purchase (and the several obligations of the Underwriters at the additional time of purchase are subject to the accuracy of the representations and warranties on the part of the TEPPCO Entities on the date hereof and at the time of purchase (unless previously waived) and at the additional time of purchase, as the case may be, to the accuracy of the statements of the Partnership made in any certificates pursuant to the provisions hereof, to the performance by the Partnership of its obligations hereunder and to the following additional conditions precedent: (a) The Partnership shall furnish to the Underwriters at the time of purchase and at the additional time of purchase, as the case may be (i) opinions of Vinson & Elkins, L.L.P., counsel for the Partnership, addressed to the Underwriters and dated the time of purchase, as set forth in Exhibit B and (ii) opinions of James C.

(l) Between the time of execution of this Agreement and the time of purchase or additional time of purchase, as the case may be, there shall not have occurred any downgrading, nor shall any notice or announcement have been given or made of (i) any intended or potential downgrading or (ii) any review or possible change that does not indicate an improvement, in the rating accorded any securities of, or securities 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. (m) Since the respective dates as of which information is given in the Registration Statement and the Prospectus, there shall have been no litigation or other proceeding instituted against any of the TEPPCO Entities or their subsidiaries or any of their respective officers or directors in their capacities as such, before or by any Federal, state or local court, commission, regulatory body, administrative agency or other governmental body, domestic or foreign, in which litigation or proceeding an unfavorable ruling, decision or finding would have a Material Adverse Effect. (n) Each of the representations and warranties of the Partnership contained herein shall be true and correct in all material respects at the time of purchase or the additional time of purchase, as the case may be, as if made at the time of purchase or the additional time of purchase, as the case may be, and all covenants and agreements herein contained to be performed on the part of the Partnership and all conditions herein contained to be fulfilled or complied with by the Partnership at or prior to the time of purchase or additional time of purchase, as the case may be, shall have been duly performed, fulfilled or complied with; provided, however, that if any such representation or warranty is already qualified by materiality, for purposes of determining whether this condition has been satisfied, such representation or warranty as so qualified must be true and correct in all respects. (o) The Units shall be qualified for sale in such states as the Underwriters may reasonably request, each such qualification shall be in effect and not subject to any stop order or other proceeding at the time of purchase or additional time of purchase, as the case may be. 7. Effective Date of Agreement; Termination. This Agreement shall become effective when the parties hereto have executed and delivered this Agreement. The obligations of the several Underwriters hereunder shall be subject to termination in the absolute discretion of Salomon Smith Barney Inc. or any group of Underwriters (which may include Salomon Smith Barney Inc.) which has agreed to purchase in the aggregate at least 50% of the Units if, (x) since the time of execution of this Agreement or the respective dates as of which information is given in the Registration Statement and Prospectus, there has been any material adverse change, financial or otherwise (other than as referred to in the Registration Statement and Prospectus as of the date hereof), in the operations, business, condition or prospects 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 -22-

the Registration Statement and the Prospectus, or (y) since the time of execution of this Agreement there shall have occurred any downgrading, or any notice shall have been given of (i) any intended or potential downgrading or (ii) any review or possible change that does not indicate an improvement in the rating accorded any notes of, or notes 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 or, (z) if, between the time of execution of this Agreement and prior to the time of purchase or additional time of purchase, as the case may be, there shall have occurred: (i) a suspension or material limitation in trading in securities generally on the New York Stock Exchange, American Stock Exchange or NASDAQ; (ii) a suspension or material limitation in trading in Common Units of the Partnership on the New York Stock Exchange, or minimum prices with regard to the Common Units of the Partnership shall have been established on the New York Stock Exchange; (iii) a general moratorium on commercial banking activities declared either by the United States, Texas or New York State authorities, a material disruption in commercial banking or securities settlement or clearance services in the United States; (iv) the outbreak or escalation of hostilities or acts of terrorism involving the United States or the declaration by the United States of a national emergency or war; or (v) the occurrence of any other calamity or crisis or any change in financial, political or economic conditions in the United States or elsewhere, if the effect of any such event specified in clause (iv) or (v) in your judgment or in the judgment of such group of Underwriters, to make it impracticable or inadvisable to market the Units on the terms and in the manner contemplated in the Registration Statement and the Prospectus. If Salomon Smith Barney Inc. or any group of Underwriters elects to terminate this Agreement as provided in this Section 7, the Partnership and each other Underwriter shall be notified promptly by letter or telegram. If the sale to the Underwriters of the Units, as contemplated by this Agreement, is not carried out by the Underwriters for any reason permitted under this Agreement or if such sale is not carried out because any of the Partnership shall be unable to comply with any of the terms of this Agreement, the Partnership shall not be under any obligation or liability under this Agreement (except to the extent provided in Sections 4(m), 5 and 9 hereof), and the Underwriters shall be under no obligation or liability to the Partnership under this Agreement (except to the extent provided in Section 9 hereof) or to one another hereunder. 8. Increase in Underwriters' Commitments. Subject to Sections 6 and 7, if any Underwriter shall default in its obligation to take up and pay for the Units to be purchased by it hereunder (otherwise than for a reason sufficient to justify the termination of this Agreement under the provisions of Section 7 hereof) and if the number of Units which all Underwriters so defaulting shall have agreed but failed to take up and pay for does not exceed 10% of the total number of Units, the non-defaulting Underwriters shall take up and pay for (in addition to the aggregate number of Units they are obligated to purchase pursuant to Section 1 hereof) the number aggregate of Units agreed to be purchased by all such defaulting Underwriters, as hereinafter provided. Such Units shall be taken up and paid for by such non-defaulting Underwriter or Underwriters in such amount or amounts as Salomon Smith Barney Inc. may designate with the consent of each Underwriter so designated, or in the event no such designation is made, such Units shall be taken up and paid for by all non-defaulting Underwriters pro rata in proportion to the aggregate number of Units set opposite the names of such non-defaulting Underwriters in Schedule A. -23-

Without relieving any defaulting Underwriter from its obligations hereunder, the Partnership agrees with the non-defaulting Underwriters that it will not sell any Units hereunder unless all of the Units are purchased by the Underwriters (or by substituted Underwriters selected by Salomon Smith Barney Inc. with the approval of the Partnership or selected by the Partnership with the approval of Salomon Smith Barney Inc.). If a new Underwriter or Underwriters are substituted by the Underwriters or by the Partnership for a defaulting Underwriter or Underwriters in accordance with the foregoing provision, the Partnership or Salomon Smith Barney Inc. shall have the right to postpone the time of purchase for a period not exceeding five business days in order that any necessary changes in the Registration Statement and Prospectus and other documents may be effected. The term Underwriter as used in this Agreement shall refer to and include any Underwriter substituted under this Section 8 with like effect as if such substituted Underwriter had originally been named in Schedule A. If the aggregate number of Units which the defaulting Underwriter or Underwriters agreed to purchase exceeds 10% of the total of Units which all Underwriters agreed to purchase hereunder, and if neither the non-defaulting Underwriters nor the Partnership shall make arrangements within the five business day period stated above for the purchase of all the Units which the defaulting Underwriter or Underwriters agreed to purchase hereunder, this Agreement shall be terminated without further act or deed and without any liability on the part of the Partnership to any non-defaulting Underwriter and without any liability on the part of any non-defaulting Underwriter to the Partnership. Nothing in this paragraph, and no action taken hereunder, shall relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement. 9. Indemnity and Contribution. (a) The Partnership agrees to indemnify, defend and hold harmless each Underwriter, its partners, directors, officers, employees, agents and any person who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and the successors and assigns of all the foregoing persons from and against any loss, damage, expense, liability or claim (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) which, jointly or severally, any such Underwriter or person may incur under the Securities Act, the Exchange Act, the common law or otherwise, insofar as such loss, damage, expense, liability or claim arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or in the Registration Statement as amended by any post-effective amendment thereof by the Partnership), in a Prospectus (the term "Prospectus" for the purpose of this Section 9 being deemed to include any preliminary prospectus filed as part of the Registration Statement, the Prospectus (as previously defined) and the Prospectus as amended or supplemented by the Partnership), or in any documents filed under the Exchange Act and deemed to be incorporated by reference into the Prospectus, or in any application or other document executed by or on behalf of any of the TEPPCO Entities or their subsidiaries or based on written information furnished by or on behalf -24-

of any of the TEPPCO Entities or their subsidiaries filed in any jurisdiction in order to qualify the Units under the securities laws thereof or filed with the Commission, or arises out of or is based upon any omission or alleged omission to state a material fact required to be stated in such Registration Statement, Prospectus or other such documents or necessary to make the statements made therein not misleading, except insofar as any such loss, damage, expense, liability or claim arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in and in conformity with information furnished in writing by or on behalf of any Underwriter through Salomon Smith Barney Inc. to the Partnership expressly for use with reference to such Underwriter in such Registration Statement or such Prospectus (which comprises only such information referred to in the second paragraph of Section 3(a) of this Agreement) or arises out of or is based upon any omission or alleged omission to state a material fact in connection with such information required to be stated in such Registration Statement, Prospectus or other such documents or necessary to make such information not misleading; provided however, that with respect to any untrue statement or omission of material fact made in any preliminary prospectus, the indemnity agreement contained in this Section 9(a) shall not inure to the benefit of any Underwriter from whom the person asserting any such loss, claim, damage or liability purchased the securities concerned, to the extent that any such loss, claim, damage or liability of such Underwriter occurs under the circumstance where it shall have been determined by a court of competent jurisdiction by final and nonappealable judgment that (w) the Partnership had previously furnished copies of the Prospectus to the Underwriters, (x) delivery of the Prospectus was required by the Securities Act to be made to such person, (y) the untrue statement or omission of a material fact contained in the preliminary prospectus was corrected in the Prospectus and (z) there was not sent or given to such person, at or prior to the written confirmation of the sale of such securities to such person, a copy of the Prospectus. This indemnity agreement will be in addition to any liability that the Partnership might otherwise have. If any action, suit or proceeding (together, a "Proceeding") is brought against an Underwriter or any such person in respect of which indemnity may be sought against the Partnership pursuant to the foregoing paragraph, such Underwriter or such person shall promptly notify the General Partner in writing of the institution of such Proceeding and the Partnership shall assume the defense of such Proceeding, including the employment of counsel reasonably satisfactory to such indemnified party and payment of all fees and expenses, provided, however, that the omission to so notify the General Partner (or any omission of notice under Section 9(c)) shall not relieve the Partnership from any liability which the Partnership may have to any Underwriter or any such person or otherwise. Such Underwriter or controlling person shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such Underwriter or such controlling person unless the employment of such counsel shall have been authorized in writing by the General Partner in connection with the defense of such Proceeding or the Partnership shall not have, within a reasonable period of time in light of the circumstances, employed counsel to have charge of the defense of such Proceeding or such indemnified party or parties shall have reasonably concluded (based on advice of counsel) that there may be defenses available to it or them which are different from, additional to or in competition with those available to the Partnership (in which case the Partnership shall not have the right to direct the defense of such Proceeding on behalf of the indemnified party or parties), in any of which events such fees and expenses shall be borne by the Partnership and paid as incurred (it being understood, however, that the Partnership shall not be liable for the expenses of more than one separate counsel (in addition to any local -25-

counsel) in any one Proceeding or series of related Proceedings in the same jurisdiction representing the indemnified parties who are parties to such Proceeding). The Partnership shall not be liable for any settlement of any such claim 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 the second sentence of this paragraph, then the indemnifying party agrees that it shall be liable for any settlement of any 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. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened Proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such 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 agrees to indemnify, defend and hold harmless the Partnership, each director and officer and any person who controls the Partnership within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and the successors and assigns of all the foregoing persons from and against any loss, damage, expense, liability or claim (including the reasonable cost of investigation) which, jointly or severally, the Partnership or any such person may incur under the Securities Act, the Exchange Act, the common law or otherwise, insofar as such loss, damage, expense, liability or claim arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in and in conformity with information furnished in writing by or on behalf of such Underwriter through Salomon Smith Barney Inc. to the Partnership expressly for use with reference to such Underwriter in the Registration Statement (or in the Registration Statement as amended by any post-effective amendment thereof by the Partnership) or in a Prospectus (which comprises only such information referred to in the second paragraph of Section 3(a) of this Agreement), or arises out of or is based upon any omission or alleged omission to state a material fact in connection with such information required to be stated in such Registration Statement or such Prospectus or necessary to make such information not misleading. This indemnity will be in addition to any liability that each Underwriter might otherwise have; provided, however, that in no case shall any Underwriter be liable or responsible for any amount in excess of the underwriting discounts and commissions received by such Underwriter. If any Proceeding is brought against the Partnership or any such person in respect of which indemnity may be sought against any Underwriter pursuant to the foregoing paragraph, the Partnership or such person shall promptly notify such Underwriter in writing of the institution of such Proceeding and such Underwriter shall assume the defense of such Proceeding, including the employment of counsel reasonably satisfactory to such indemnified party and payment of all fees and expenses; provided, however, that the omission to so notify such Underwriter (or any omission of notice under Section 9(c)) shall not relieve such -26-

Underwriter, from any liability which such Underwriter may have to the Partnership or any such person or otherwise. The Partnership or such person shall have the right to employ its own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of the Partnership or such person unless the employment of such counsel shall have been authorized in writing by such Underwriter in connection with the defense of such Proceeding or such Underwriter shall not have, within a reasonable period of time in light of the circumstances, employed counsel to have charge of the defense of such Proceeding or such indemnified party or parties shall have reasonably concluded that there may be defenses available to it or them which are different from or additional to or in conflict with those available to such Underwriter (in which case such Underwriter shall not have the right to direct the defense of such Proceeding on behalf of the indemnified party or parties, but such Underwriter may employ counsel and participate in the defense thereof but the fees and expenses of such counsel shall be at the expense of such Underwriter), in any of which events such fees and expenses shall be borne by such Underwriter and paid as incurred (it being understood, however, that such Underwriter shall not be liable for the expenses of more than one separate counsel in addition to any local counsel in any one Proceeding or series of related Proceedings in the same jurisdiction representing the indemnified parties who are parties to such Proceeding). Anything in this paragraph to the contrary notwithstanding, no Underwriter shall be liable for any settlement of any such 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 by the second sentence of this paragraph, then the indemnifying party agrees that it shall be liable for any settlement of any 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. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened Proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such Proceeding. (c) If the indemnification provided for in this Section 9 is unavailable to an indemnified party under subsections (a) and (b) of this Section 9 in respect of any losses, damages, expenses, liabilities or claims referred to therein, then each applicable indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, damages, expenses, liabilities or claims (i) in such proportion as is appropriate to reflect the relative benefits received by the Partnership on the one hand and the Underwriters on the other hand from the offering of the Units or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above 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, damages, expenses, liabilities or claims, as well as any other relevant equitable considerations. The -27-

relative benefits received by the Partnership on the one hand and the Underwriters on the other shall be deemed to be in the same respective proportion as the total proceeds from the offering (net of underwriting discounts and commissions but before deducting expenses) received by the Partnership and the underwriting discounts and commissions received by the Underwriters. The relative fault of the Partnership on the one hand and of the Underwriters on the other shall be determined by reference to, among other things, whether the untrue statement or alleged untrue statement of a material fact or omission or alleged omission relates to information supplied by the Partnership or by the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses, claims, damages and liabilities referred to in this subsection shall be deemed to include any legal or other fees or expenses reasonably incurred by such party in connection with investigating, preparing to defend or defending any Proceeding. (d) The Partnership and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 9 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in subsection (c) above. Notwithstanding the provisions of this Section 9, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Units underwritten by such Underwriter and distributed to the public were offered to the public exceeds the amount of any damage which such Underwriter has otherwise been required to pay by reason of such untrue statement or alleged untrue statement or omission or alleged omission. 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. The Underwriter's obligations to contribute pursuant to this Section 9 are several in proportion to their respective underwriting commitments and not joint. The indemnity and contribution agreements contained in this Section 9 and the covenants, warranties and representations of the Partnership contained in this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of any Underwriter, its partners, directors, officers, employees, agents or any person (including each partner, officer or director of such person) who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, or by or on behalf of the Partnership, the directors and officers of the General Partner or any person who controls any of the Partnership within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and shall survive any termination of this Agreement or the issuance and delivery of the Units. The Partnership and each Underwriter agree promptly to notify each other of the commencement of any Proceeding against it and, in the case of the Partnership, against any of the General Partner's officers or directors, in connection with the issuance and sale of the Units, or in connection with the Registration Statement or Prospectus. 10. Notices. Except as otherwise herein provided, all statements, requests, notices and agreements shall be in writing or by telegram and, if to the Underwriters, shall be sufficient in all respects if delivered or sent in care of Salomon Smith Barney Inc., 388 Greenwich, 34th Floor, New York, N.Y. 10013, Attention: General Counsel (fax: (212) 816-7912) and, if to the Partnership, shall be sufficient in all respects if delivered or sent to the Partnership at the offices of the General Partner at 2929 Allen Parkway, P.O. Box 2521, Houston, Texas 77252-2521, Attention: James C. Ruth. -28-

11. Governing Law; Construction. This Agreement and any claim, counterclaim or dispute of any kind or nature whatsoever arising out of or in any way relating to this Agreement ("Claim"), directly or indirectly, shall be governed by, and construed in accordance with, the laws of the State of New York. The section headings in this Agreement have been inserted as a matter of convenience of reference and are not a part of this Agreement. 12. Submission to Jurisdiction. Except as set forth below, no Claim may be commenced, prosecuted or continued in any court other than the courts of the State of New York located in the City and County of New York or in the United States District Court for the Southern District of New York, which courts shall have jurisdiction over the adjudication of such matters, and the Partnership consents to the jurisdiction of such courts and personal service with respect thereto. The Partnership hereby consents to personal jurisdiction, service and venue in any court in which any Claim arising out of or in any way relating to this Agreement is brought by any third party against Salomon Smith Barney Inc. or any indemnified party. Each of Salomon Smith Barney Inc. and the Partnership (on its behalf and, to the extent permitted by applicable law, on behalf of its holders and affiliates) waives all right to trial by jury in any action, proceeding or counterclaim (whether based upon contract, tort or otherwise) in any way arising out of or relating to this Agreement. The Partnership agrees that a final judgment in any such action, proceeding or counterclaim brought in any such court shall be conclusive and binding upon the Partnership and may be enforced in any other courts in the jurisdiction of which the Partnership is or may be subject, by suit upon such judgment. 13. Parties at Interest. The Agreement herein set forth has been and is made solely for the benefit of the Underwriters and the Partnership and, to the extent provided in Section 9 hereof, the controlling persons, directors and officers referred to in such section, and their respective successors, assigns, heirs, personal representatives and executors and administrators. No other person, partnership, association or corporation (including a purchaser, as such purchaser, from any of the Underwriters) shall acquire or have any right under or by virtue of this Agreement. The term "successors and assigns" as used in this Agreement shall not include a purchaser, as such purchaser, of Units from the Underwriters. 14. Counterparts. This Agreement may be signed by the parties in one or more counterparts which together shall constitute one and the same agreement among the parties. 15. Successors and Assigns. This Agreement shall be binding upon the Underwriters and the Partnership and its successors and assigns and any successor or assign of any substantial portion of the Partnership's and any of the Underwriters' respective businesses and/or assets. If the foregoing correctly sets forth the understanding among the Partnership and the Underwriters, please so indicate in the space provided below for the purpose, whereupon this letter and your acceptance shall constitute a binding agreement among the Partnership and the Underwriters, severally.

Box 2521 Houston, Texas 77252-2521 Ladies and Gentlemen: We have acted as counsel to TEPPCO Partners, L.P., a Delaware limited partnership (the "Partnership"), in connection with the offering by the Partnership of up to 3,938,750 units (including an option to purchase up to 513,750 units) representing limited partner interests in the Partnership (the "Units").

A prospectus supplement dated April 2, 2003 (the "Prospectus"), which together with the base prospectus filed as a part of the Registration Statement shall constitute part of the Prospectus, has been filed pursuant to Rule 424(b) promulgated under the Securities Act. As the basis for the opinion hereinafter expressed, we examined such statutes, including the Delaware Uniform Revised Limited Partnership Act, corporate records and documents, certificates of public officials, and other instruments and documents as we deemed necessary or advisable for the purposes of this opinion. In such examinations, we assumed the authenticity of all documents submitted to us as originals and the conformity with the original documents of all documents submitted to us as copies. As to various questions of fact material to this opinion, we have relied upon statements and certificates of officers of Texas Eastern Products Pipeline Company, LLC, a Delaware limited liability company and general partner of the Partnership. Without limiting the foregoing, we have examined (i) the Registration Statement, including the Prospectus, (ii) the Third Amended and Restated Agreement of Limited Partnership of the Partnership, dated as of September 21, 2001 and (iii) the Underwriting Agreement, dated April 2, 2003, among the Partnership and Salomon Smith Barney Inc., A.G. Edwards & Sons, Inc., Lehman Brothers Inc., UBS Warburg LLC and Goldman, Sachs & Co., as underwriters (the "Underwriting Agreement"). In connection with this opinion, we have assumed that all Units will be issued and sold in compliance in the manner stated in the Prospectus and the Underwriting Agreement. Based on the foregoing, we are of the opinion that the Units, when issued and delivered to and paid for by the Underwriters in accordance with the terms of the Underwriting Agreement, will be validly issued, fully paid and nonassessable except as described in the Prospectus. The opinions expressed herein are limited exclusively to the federal laws of the United States of America and the Revised Uniform Limited Partnership Act of the State of Delaware and the Constitution
