PAINEWEBBER INCORPORATED
LEHMAN BROTHERS INC.
DAIN RAUSCHER WESSELS, A DIVISION OF DAIN RAUSCHER INCORPORATED
ING BARINGS LLC
c/o PaineWebber Incorporated
1285 Avenue of the Americas
New York, New York 10019

Ladies and Gentlemen:

         EOTT Energy Partners, L.P., a Delaware limited partnership (the
"Partnership"), proposes to sell common units representing limited partner
interests in the Partnership (the "Common Units") to PaineWebber Incorporated,
Lehman Brothers Inc., Dain Rauscher Wessels, a division of Dain Rauscher
Incorporated and ING Barings LLC (the "Underwriters") in an aggregate amount of
3,500,000 Common Units (the "Firm Units"). The Partnership has also agreed to
grant to the Underwriters an option (the "Option") to purchase up to additional
525,000 Common Units representing limited partner interests (the "Option Units")
on the terms and for the purposes set forth in Section 1(b). The Firm Units and
the Option Units are hereinafter referred to as the "Units."

         The public offering price per Common Unit for the Units and the
purchase price per Common Unit for the Units to be paid by the Underwriters
shall be agreed upon by the Partnership and the Underwriters, and such agreement
shall be set forth in a separate written instrument substantially in the form of
Exhibit A hereto (the "Price Determination Agreement"). The Price Determination
Agreement may take the form of an exchange of any standard form of written
telecommunication among the Partnership and the Underwriters and shall specify
such applicable information as is indicated in Exhibit A hereto. The offering of
the Units will be governed by this Agreement, as supplemented by the Price
Determination Agreement. From and after the date of the execution and delivery
of the Price Determination Agreement, this Agreement shall be deemed to
incorporate, and, unless the context otherwise indicates, all references
contained herein to "this Agreement" and to the phrase "herein" shall be deemed
to


<PAGE>   2


include the Price Determination Agreement.

         Each of (i) the Partnership, (ii) EOTT Energy Corp., a Delaware
corporation (both in its capacity as general partner of the Partnership and the
Operating Partnerships and in its individual capacity, the "General Partner"),
(iii) EOTT Energy Finance Corp. ("Finance Sub"), (iv) EOTT Energy Operating
Limited Partnership, a Delaware limited partnership ("Energy OLP"), (v) EOTT
Energy Pipeline Limited Partnership, a Delaware limited partnership ("Pipeline
OLP") and (vi) EOTT Energy Canada Limited Partnership, a Delaware limited
partnership ("Canada OLP" and, together with Energy OLP and Pipeline OLP, the
"Operating Partnerships") confirms as follows its agreements with the
Underwriters. All of such entities shall be referred to collectively as the
"EOTT Entities."

         1. Agreement to Sell and Purchase.

                  (a) On the basis of the representations, warranties and
agreements of the EOTT Entities herein contained and subject to all the terms
and conditions of this Agreement, the Partnership agrees to sell to each
Underwriter, and each Underwriter, severally and not jointly, agrees to purchase
from the Partnership, at the purchase price per Common Unit for the Units to be
agreed upon by the Underwriters and the Partnership in accordance with Section
1(c) hereof and set forth in the Price Determination Agreement, the number of
Firm Units set forth opposite the name of such Underwriter in Schedule I, plus
such additional number of Firm Units which such Underwriter may become obligated
to purchase pursuant to Section 8 hereof. Schedule I may be attached to the
Price Determination Agreement.

                  (b) Subject to all the terms and conditions of this Agreement,
the Partnership grants the Option to the several Underwriters to purchase,
severally and not jointly, up to 525,000 Option Units from the Partnership at
the same price per Common Unit as the Underwriters shall pay for the Firm Units.
The Option may be exercised only to cover over-allotments in the sale of the
Firm Units by the Underwriters and may be exercised in whole or in part at any
time (but not more than once) on or before the 30th day after the date of the
Price Determination Agreement, upon written or telegraphic notice (the "Option
Units Notice") by the Underwriters to the Partnership no later than 12:00 noon,
New York City time, at least two and no more than five business days before the
date specified for closing in the Option Units Notice (the "Option Closing
Date") setting forth the aggregate number of Option Units to be purchased and
the time and date for such purchase. On the Option Closing Date, the Partnership
will issue and sell to the Underwriters the number of Option Units set forth in
the Option Units Notice, and each Underwriter will purchase the percentage of
the Option Units as is equal to the percentage of Firm Units that such
Underwriter is purchasing, as adjusted by the Underwriters in such manner as
they deem advisable to avoid fractional Common Units.

                  (c) The public offering price per Common Unit for the Firm
Units and the purchase price per Common Unit for the Firm Units to be paid by
the several Underwriters shall be agreed upon and set forth in the Price
Determination Agreement.

         2. Delivery and Payment. The Firm Units to be purchased by each
Underwriter


<PAGE>   3



hereunder, in book entry form, and in such authorized denominations and
registered in such names as PaineWebber Incorporated may request, will be
represented by one or more definitive global certificates which will be
deposited by or on behalf of the Partnership with the Depository Trust Company
("DTC")or its designated custodian. Delivery to the Underwriters of the Firm
Units shall be made by or on behalf of the Partnership by causing DTC to credit
the Firm Units to the account or accounts designated by PaineWebber Incorporated
at DTC, against payment of the purchase price by wire transfer of Federal Funds
or similar same day funds to an account designated in writing by the Partnership
to PaineWebber Incorporated at least one business day prior to the Closing Date
(as hereinafter defined). Such payment shall be made at 10:00 a.m., New York
City time, on the third business day (or fourth business day, if the Price
Determination Agreement is executed after 4:30 p.m.) after the date on which the
first bona fide offering of the Units to the public is made by the Underwriters
or at such time on such other date, not later than ten business days after such
date, as may be agreed upon by the Partnership and the Underwriters (such date
is hereinafter referred to as the "Closing Date").

         To the extent the Option is exercised, delivery of the Option Units
against payment by the Underwriters (in the manner specified above) will take
place at the offices specified above for the Closing Date at the time and date
(which may be the Closing Date) specified in the Option Units Notice.

         The cost of original issue tax stamps, if any, in connection with the
issuance and delivery of the Units by the Partnership to the respective
Underwriters shall be borne by the Partnership. The Partnership will pay and
save each Underwriter and any subsequent holder of the Units harmless from any
and all liabilities with respect to or resulting from any failure or delay in
paying Federal and state stamp and other transfer taxes, if any, which may be
payable or determined to be payable in connection with the original issuance or
sale to such Underwriter of the Firm Units and Option Units.

         3. Representations and Warranties of the EOTT Entities. Each of the
EOTT Entities represents, warrants and covenants to each Underwriter that:

                  (a) The Partnership meets the requirements for use of Form S-3
and a registration statement (Registration No. 333-82269) on Form S-3 relating
to the Units (and such amendments to such registration statement as may have
been required to the date of this Agreement) has been prepared by the
Partnership in accordance with the requirements of the Securities Act of 1933,
as amended (the "Act"), and the rules and regulations (collectively referred to
as the "Rules and Regulations") of the Securities and Exchange Commission (the
"Commission")thereunder, and has been filed with the Commission. Such
registration statement has been declared effective by the Commission. Copies of
such registration statement and amendments and of each related prospectus have
been delivered to the Underwriters. The term "Registration Statement" means the
registration statement, including all financial statements, exhibits and
documents incorporated by reference therein, as from time to time amended or
supplemented pursuant to the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), Rule 415 and Rule 434 of the Rules and Regulations, or
otherwise, any registration statement filed under Rule 462 of the Rules and
Regulations as such registration statement may


<PAGE>   4



be amended from time to time and all information contained in the final
prospectus filed with the Commission pursuant to Rule 424(b) of the Rules and
Regulations. The term "Prospectus" means the prospectus constituting a part of
the Registration Statement and any amendments or supplements to such prospectus,
including without limitation the prospectus supplement filed with the Commission
in connection with the proposed sale of Units contemplated by this Agreement
(the "Prospectus Supplement"), through the date of such Prospectus Supplement.
Any reference herein to the Registration Statement or the Prospectus shall be
deemed to refer to and include the documents incorporated by reference therein
pursuant to Item 12 of Form S-3 which were filed under the Exchange Act, on or
before the date hereof or are so filed hereafter. Any reference herein to the
terms "amend," "amendment" or "supplement" with respect to the Registration
Statement or the Prospectus shall be deemed to refer to and include any such
document filed or to be filed under the Exchange Act after the date of the
Prospectus, and deemed to be incorporated therein by reference.

                  (b) On the date the Registration Statement was declared
effective by the Commission (the "Effective Date"), at all times subsequent to
and including the Closing Date and, if later, the Option Closing Date and when
any post-effective amendment to the Registration Statement becomes effective or
any amendment or supplement to the Prospectus is filed with the Commission, the
Registration Statement and the Prospectus (as amended or as supplemented if the
Partnership shall have filed with the Commission any amendment or supplement
thereto), including the financial statements included or incorporated by
reference in the Prospectus or the Registration Statement, did or will comply
with all applicable provisions of the Act, the Exchange Act, the rules and
regulations thereunder (the "Exchange Act Rules and Regulations") and the Rules
and Regulations and will contain all statements required to be stated therein in
accordance with the Act, the Exchange Act, the Exchange Act Rules and
Regulations and the Rules and Regulations. On the Effective Date and when any
post-effective amendment to the Registration Statement becomes effective, no
part of the Registration Statement or any such amendment did or will contain any
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary in order to make the statements therein not
misleading. At the Effective Date, the date the Prospectus or any amendment or
supplement to the Prospectus is filed with the Commission and at the Closing
Date and, if later, the Option Closing Date, the Prospectus did not or will not
contain any untrue statement of a material fact or omit to state a material fact
necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading. The foregoing representations and
warranties in this Section 3(b) do not apply to any statements or omissions made
in reliance on and in conformity with information relating to any Underwriter
furnished in writing to the Partnership by the Underwriters specifically for
inclusion in the Registration Statement or Prospectus or any amendment or
supplement thereto. For all purposes of this Agreement (i) the amounts of the
selling concession and reallowance set forth in the Prospectus (ii) the
paragraph regarding stabilization in the section captioned "Underwriting"in the
Prospectus, and (iii) the number of Common Units to be purchased by each
Underwriter set forth in the section captioned "Underwriting" in the Prospectus

to the Partnership by the Underwriters specifically for inclusion in the
Registration Statement or the Prospectus. The Partnership has not distributed

<PAGE>   5

has been issued by the Commission.

                  (c) The documents which are incorporated by reference in the
Registration Statement and the Prospectus or from which information is so
incorporated by reference, when they became effective or were filed with the
Commission, as the case may be, complied in all material respects with the
requirements of the Act or the Exchange Act, as applicable, the Exchange Act
Rules and Regulations and the Rules and Regulations and none of such documents
contained an untrue statement of a material fact or omitted to state a material
fact required to be stated therein or necessary to make the statement therein
not misleading; and any further documents so filed and incorporated by reference
subsequent to the Closing Date shall, when they are filed with the Commission,
conform in all material respects with the requirements of the Act and the
Exchange Act, as applicable, the Exchange Act Rules and Regulations and the
Rules and Regulations and will not contain an untrue statement of a material
fact or omit to state a material fact required to be stated therein or necessary
to make the statement therein not misleading.

                  (d) The only subsidiaries (as defined in the Rules and
Regulations) of the Partnership are the Operating Partnerships and the Finance
Sub. Each of the Partnership and the Operating Partnerships was duly formed and
is validly existing and in good standing under the Delaware Revised Uniform
Limited Partnership Act (the "Delaware Act"). Each of the Partnership and the
Operating Partnerships has, and at the Closing Date will have, full power and
authority to conduct the activities conducted by it, to own or lease all the
assets owned or leased by it and to conduct its business in all material
respects as described in the Registration Statement and the Prospectus. Each of
the Partnership and the Operating Partnerships is, and at the Closing Date will
be, duly licensed or qualified to do business and in good standing as a foreign
limited partnership in all jurisdictions in which the failure so to qualify or
register would have a material adverse effect upon it or subject it to any
material liability or disability. All of the outstanding shares of capital stock
of the Finance Sub have been duly authorized and validly issued and are fully
paid and nonassessable and are owned by the Partnership free and clear of all
liens and encumbrances and claims whatsoever. The Partnership is the sole
limited partner of Energy OLP, and Energy OLP is the sole limited partner of
Pipeline OLP and Canada OLP, in each case with a limited partner interest of
99.0%. Such limited partner interests have been duly authorized by the
respective Amended and Restated Agreements of Limited Partnership of the
Operating Partnerships (the "Operating Partnership Agreements"), have been
validly issued in accordance with the respective Operating Partnership
Agreements and are fully paid and non-assessable, except to the extent such
non-assessability may be affected by Section 17-607 of the Delaware Revised
Uniform Limited Partnership Act, as amended. The Partnership owns such limited
partner interests free and clear of all liens, encumbrances, security interests,
equities, charges or claims, except for such liens, encumbrances, security
interests, equities, charges or claims as are not, individually or in the
aggregate, material or except as described in the Prospectus. Except for such
limited partner interests and the stock of the Finance Sub, the Partnership does
not own, and at the Closing Date will not own, directly or indirectly, any
shares of stock or any other equity or long-term debt securities of any
corporation or have an equity interest in any firm, partnership, joint venture,
association or other entity. Complete and correct


<PAGE>   6



copies of the Amended and Restated Agreement of Limited Partnership of the
Partnership (the "Partnership Agreement") and each of the Operating Partnership
Agreements have been delivered to the Underwriters, and no changes therein will
be made subsequent to the date hereof and prior to the Closing Date.

                  (e) The limited partners of the Partnership hold limited
partner interests in the Partnership aggregating 99%, such limited partner
interests being represented by 14,976,011 Common Units and 9,000,000 units
representing subordinated limited partner interests ("Subordinated Units")(the
Common Units and the Subordinated Units are collectively referred to as the
"Limited Partner Units"); the Limited Partner Units are the only limited partner
interests of the Partnership that are issued and outstanding; the Limited
Partner Units have been, and the Common Units to be issued and sold by the
Partnership will be, duly authorized and validly issued under the Partnership
Agreement, fully paid and nonassessable, except as such nonassessability may be
affected by Section 17-607 of the Delaware Revised Uniform Limited Partnership
Act, as amended, and will not be subject to any preemptive or similar right or
voting or transfer restriction. The description of the Common Units in the
Registration Statement and the Prospectus is, and at the Closing Date will be,
complete and accurate in all material respects. Except as set forth in the
Prospectus, the Partnership does not have outstanding, and at the Closing Date
will not have outstanding, any options to purchase, or any rights or warrants to
subscribe for, or any securities or obligations convertible into, or any
contracts or commitments to issue or sell, any limited partner interests or
shares of stock in the Partnership, the Operating Partnerships, or the Finance
Sub pursuant to the Partnership Agreement, the Operating Partnership Agreements,
any certificate of incorporation or other governing documents or any agreement
or other instrument to which any of the EOTT entities is a party or by which any
of them may be bound.

                  (f) Each of the General Partner and the Finance Sub is a
corporation duly organized, validly existing and in good standing under the laws
of the State of Delaware. Each of the General Partner and the Finance Sub has,
and at the Closing Date will have, full power and authority to conduct all the
activities conducted by it, to own or lease all the assets owned or leased by it
and to conduct its business in all material respects as described in the
Registration Statement and the Prospectus. Each of the General Partner and the
Finance Sub is, and at the Closing Date will be, duly licensed or qualified to
do business and in good standing as a foreign corporation in all jurisdictions
in which the failure so to qualify or register would have a material adverse
effect upon it or subject it to any material liability or disability. The
General Partner is the sole general partner of the Partnership and the Operating
Partnerships, in each case with a general partner interest of 1%. Such general
partner interests have been duly authorized by the Partnership Agreement and the
respective Operating Partnership Agreements, have been validly issued in
accordance with the Partnership Agreement and the respective Operating
Partnership Agreements, and are owned of record by the General Partner, free and
clear of all liens, encumbrances, security interests, equities, charges or
claims, except for such liens, encumbrances, security interests, equities,
charges or claims as are not, individually or in the aggregate, material or
except as described in the Prospectus. Complete and correct copies of the
certificate of incorporation and the by-laws of the General Partner and the
Finance Sub and all amendments thereto have been delivered to the Underwriters,
and no changes therein will be


<PAGE>   7

made subsequent to the date hereof and prior to the Closing Date.

                  (g) The financial statements and schedules included or
incorporated by reference in the Registration Statement or the Prospectus
present fairly the consolidated financial condition of the Partnership as of the
respective dates thereof and the consolidated results of operations and cash
flows of the Partnership for the respective periods covered thereby, all in
conformity with generally accepted accounting principles applied on a consistent
basis throughout the entire period involved, except as otherwise disclosed
therein or in the Prospectus. No other financial statements or schedules are
required by the Act, the Exchange Act or the Rules and Regulations to be
included in the Registration Statement or the Prospectus. Arthur Andersen L.L.P.
(the "Accountants"), who have reported on such financial statements and
schedules, are independent accountants with respect to the EOTT Entities, as
required by the Act and the Rules and Regulations. The statements included in
the Registration Statement with respect to the Accountants pursuant to Rule 509
of Regulation S-K of the Rules and Regulations are true and correct in all
material respects.

                  (h) The Partnership maintains a system of internal accounting
controls sufficient to provide reasonable assurance that (i) transactions are
executed in accordance with management's general or specific authorization; (ii)
transactions are recorded as necessary to permit preparation of financial
statements in conformity with generally accepted accounting principles and to

approval, any related constraints on operating activities and any potential
liabilities to third parties (collectively, "Environmental Liabilities")).
Except as set forth in the Registration Statement and the Prospectus, there are
no Environmental Liabilities which would, singly or in the aggregate, have a
material adverse effect on the condition (financial or otherwise) or on the
earnings, business, properties, business prospects or operations of the EOTT

or with respect to which any of the EOTT Entities could incur any liability
under ERISA (collectively, the "Benefit Plans"), no event has occurred and, to
the best knowledge of each of the EOTT Entities, there exists no condition or
set of circumstances, in connection with which any of the EOTT Entities could be

amended) or any applicable agreement that



<PAGE>   12

condition (financial or otherwise) or results of operations of the EOTT
Entities, taken as a whole.

                  (cc) Each of the EOTT Entities has reviewed its operations
and those of any third parties with which the EOTT Entities have a material
relationship to evaluate the extent to which the business or operations of the
EOTT Entities will be affected by the Year 2000 Problem. As a result of such
review, the EOTT Entities have no reason to believe, and do not believe, that
(other than as described in the Prospectus) the Year 2000 Problem will have a
material adverse effect on the general affairs, management, the current or
future consolidated financial position, partners' capital or results of
operations of the EOTT Entities or result in any material loss or interference
with any of the EOTT Entities' business or operations. The "Year 2000 Problem"as
used herein means any significant risk that computer hardware or software used
in the receipt, transmission, processing, manipulation, storage, retrieval,
retransmission or other utilization of data or in the operation of mechanical or
electrical systems of any kind will not, in the case of dates or time periods
occurring after December 31, 1999, function at least as effectively as in the
case of dates or time periods occurring prior to January 1, 2000.

binding agreement of the General Partner, enforceable against the General
Partner in accordance with its terms and (ii) each of the Operating Partnership
Agreements is a valid and legally binding agreement of such parties, enforceable
against the General Partner and the Partnership in accordance with its terms,
except as the enforceability of such agreements may be affected by bankruptcy,
insolvency, reorganization and other laws of general applicability relating to
or affecting creditors' rights and general equitable principles.

of the National Association of Securities Dealers, Inc., as of the date hereof
and as of the Closing Date, the Partnership meets, and will meet, the standards
for use of Form S-3 as in effect prior to October 21, 1992.

Statement or the Prospectus in order to make the statements therein, in light of
the circumstances under which they were made, not misleading and (5) of receipt

order at the earliest possible moment.

                  (c) The Partnership will furnish to the Underwriters, without
charge, two signed copies of the Registration Statement and of any
post-effective amendment thereto, including financial statements and schedules,

Underwriters and by all dealers to whom the Units may be sold, both in
connection with the offering or sale of the Units and for any period of time

forth in the Prospectus in order to make any statement therein, in the light of
the circumstances under which it was made, not misleading, or if it is necessary
to supplement or amend the Prospectus to comply with law, the Partnership will
forthwith prepare and duly file with the Commission an appropriate supplement or
amendment thereto, and will deliver to each Underwriter, without charge, such
number of copies thereof as the Underwriters may reasonably request. The
Partnership shall not file any document under the Exchange Act before the
completion of the distribution of the Common Units by the Underwriters (which
includes the distribution of any Common Units pursuant to the Option, if
exercised), of the Units by the Underwriters if such document would be deemed to
be incorporated by reference into the Prospectus unless the filing of such
document is approved by the Underwriters after reasonable notice thereof.

Underwriters, the Partnership will cooperate with the Underwriters and counsel
to the Underwriters in connection with the registration or qualification of the
Units for offer and sale under the securities or Blue Sky laws of such
jurisdictions as the Underwriters may request; provided, that in no event shall
the Partnership be obligated to qualify to do business in any jurisdiction where
it is not now so qualified or to take any action which would subject it to
general service of process in any jurisdiction where it is not now so subject.

litigation or proceeding an unfavorable ruling, decision or finding could
materially and adversely affect the business, properties, business prospects,
condition (financial or otherwise) or results of operations of the EOTT
Entities, taken as a whole.

                  (e) Each of the representations and warranties of the EOTT
Entities contained herein shall be true and correct in all material respects at
the Closing Date, and with respect to the Option Units, at the Option Closing
Date as if made at the Option Closing Date, and all covenants and agreements
herein contained to be performed on the part of the EOTT Entities and all
conditions herein contained to be fulfilled or complied with by the EOTT
Entities at or prior to the Closing Date, and with respect to the Option Units,
at the Option Closing Date, shall have




<PAGE>   17

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.

                  (f) The Underwriters shall have received an opinion, dated the
Closing Date, and with respect to the Option Units, at the Option Closing Date,
and satisfactory in form and substance to counsel for the Underwriters, from
Vinson & Elkins L.L.P., counsel to the EOTT Entities, to the effect set forth in
Exhibit C.

                  (g) The Underwriters shall have received an opinion, dated the
Closing Date, and with respect to the Option Units, at the Option Closing Date,
and satisfactory in form and substance to counsel for the Underwriters, from
Stephen W. Duffy, Esq., General Counsel of the General Partner, to the effect
set forth in Exhibit D.

                  (h) The Underwriters shall have received an opinion, dated the
Closing Date, and with respect to the Option Units, at the Option Closing Date,
from Andrews & Kurth L.L.P. , counsel to the Underwriters which opinion shall be
satisfactory in all respects to the Underwriters.

                  (i) On the date of this Agreement, Arthur Andersen LLP shall
have furnished to the Underwriters a letter, dated the date of its delivery,
addressed to the Underwriters and in form and substance satisfactory to the
Underwriters, confirming that they are independent accountants with respect to
the EOTT Entities as required by the Act and the Rules and Regulations, and with
respect to the financial and other statistical and numerical information
contained in the Registration Statement or incorporated by reference therein. At
the Closing Date and, with respect to the Option Units, at the Option Closing
Date, Arthur Andersen LLP shall have furnished to the Underwriters a letter,
dated the date of its delivery, which shall confirm, on the basis of a review in
accordance with the procedures set forth in the letter from Arthur Andersen LLP,
that nothing has come to their attention during the period from the date of the
letter referred to in the prior sentence to a date (specified in the letter) not
more than five days prior to the Closing Date and the Option Closing Date which
would require any change in their letter dated the date hereof, if it were
required to be dated and delivered at the Closing Date and the Option Closing
Date. Arthur Andersen LLP shall have furnished to the Underwriters a review
report with respect to the interim financial statements for the six-month period
ended June 30, 1999.

                  (j) At the Closing Date and, with respect to the Option Units,
at the Option Closing Date, there shall be furnished to the Underwriters an
accurate certificate, dated the date of its delivery, signed by each of the
Chief Executive Officer and the Chief Financial Officer of the General Partner,
in form and substance satisfactory to the Underwriters, to the effect that:

                           (i) Each signer of such certificate has carefully
         examined the Registration Statement, the Prospectus (including any
         documents filed under the Exchange Act and deemed to be incorporated by
         reference into the Prospectus) and (A) as



<PAGE>   18

         of the date of such certificate, such documents are true and correct in
         all material respects and do not omit to state a material fact required
         to be stated therein or necessary in order to make the statements
         therein not untrue or misleading and (B) since the Effective Date, no
         event has occurred as a result of which it is necessary to amend or
         supplement the Prospectus in order to make the statements therein not
         untrue or misleading in any material respect and there has been no
         document required to be filed under the Exchange Act and the Exchange
         Act Rules and Regulations that upon such filing would be deemed to be
         incorporated by reference into the Prospectus that has not been so
         filed;

                           (ii) Each of the representations and warranties of
         the EOTT Entities contained in this Agreement were, when originally
         made, and are, at the time such certificate is delivered, true and
         correct in all material respects;

                           (iii) Each of the covenants required herein to be
         performed by the EOTT Entities on or prior to the delivery of such
         certificate has been duly, timely and fully performed and each
         condition herein required to be complied with by the EOTT Entities on
         or prior to the date of such certificate has been duly, timely and
         fully complied with; and

                           (iv) Since the respective dates as of which
         information is given in the Registration Statement and the Prospectus,
         (A) there has not been, and no development has occurred which could
         reasonably be expected to result in, a material adverse change in the
         general affairs, business, business prospects, properties, management,
         condition (financial or otherwise) or results of operations of the EOTT
         Entities, taken as a whole, whether or not arising from transactions in
         the ordinary course of business, in each case other than as set forth
         in or contemplated by the Registration Statement and the Prospectus and
         (B) none of the EOTT Entities has sustained any material loss or
         interference with its business or properties from fire, explosion,
         flood or other casualty, whether or not covered by insurance, or from
         any labor dispute or any court or legislative or other governmental
         action, order or decree, which is not set forth in the Registration
         Statement and the Prospectus;

and such other matters as the Underwriters may reasonably request.

                  (k) On or prior to the Closing Date, the Underwriters shall
have received the executed agreements referred to in Section 4(n).

                  (l) 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 on the Closing Date
and the Option Closing Date.

                  (m) Prior to the Closing Date, the Units shall have been duly
authorized for listing by the New York Stock Exchange upon official notice of
issuance.

                  (n) The EOTT Entities shall have furnished to the Underwriters
such




<PAGE>   19

certificates, in addition to those specifically mentioned herein, as the
Underwriters may have reasonably requested as to the accuracy and completeness
at the Closing Date and the Option Closing Date of any statement in the
Registration Statement or the Prospectus or any documents filed under the
Exchange Act and deemed to be incorporated by reference into the Prospectus, as
to the accuracy at the Closing Date and the Option Closing Date of the
representations and warranties of the EOTT Entities herein, as to the
performance by the EOTT Entities of its obligations hereunder, or as to the
fulfillment of the conditions concurrent and precedent to the obligations
hereunder of the Underwriters.

         6. Indemnification. (a) The EOTT Entities will, jointly and severally,
indemnify and hold harmless each Underwriter, the directors, officers, employees
and agents of each Underwriter and each person, if any, who controls each
Underwriter within the meaning of Section 15 of the Act or Section 20 of the
Exchange Act from and against any and all losses, claims, liabilities, expenses
and damages (including, but not limited to, any and all investigative, legal and
other expenses reasonably 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), as and when
incurred, to which any Underwriter, or any such person, may become subject under
the Act, the Exchange Act or other Federal or state statutory law or regulation,
at common law or otherwise, insofar as such losses, claims, liabilities,
expenses or damages arise out of or are based on (i) any untrue statement or
alleged untrue statement of a material fact contained in the Registration
Statement or the Prospectus or any amendment or supplement to the Registration
Statement or the Prospectus 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 EOTT
Entities or based on written information furnished by or on behalf of any of the
EOTT Entities filed in any jurisdiction in order to qualify the Units under the
Securities Laws thereof or filed with the Commission, (ii) the omission or
alleged omission to state in such document a material fact required to be stated
in it or necessary to make the statements in it not misleading or (iii) any act
or failure to act or any alleged act or failure to act by any Underwriter in
connection with, or relating in any manner to, the Units or the offering
contemplated hereby, and which is included as part of or referred to in any
loss, claim, liability, expense or damage arising out of or based upon matters
covered by clause (i) or (ii) above (provided that the EOTT Entities shall not
be liable under this clause (iii) to the extent it is finally judicially
determined by a court of competent jurisdiction that such loss, claim,
liability, expense or damage resulted directly from any such acts or failures to
act undertaken or omitted to be taken by such Underwriter through its gross
negligence or willful misconduct); provided that the EOTT Entities will not be
liable to the extent that such loss, claim, liability, expense or damage (A)
arises from the sale of the Units in the public offering to any person by an
Underwriter and is based on an untrue statement or omission or alleged untrue
statement or omission made in reliance on and in conformity with information
relating to any Underwriter furnished in writing to the Partnership by any
Underwriter expressly for inclusion in the Registration Statement or the
Prospectus, which information consists solely of the information specified in
Section 3(b) or (B) results solely from an untrue statement of a material fact
contained in, or the omission of a material fact from, such preliminary
prospectus, which untrue statement or omission was completely corrected in the





<PAGE>   20

Prospectus (as then amended or supplemented) if the Partnership shall sustain
the burden of proving that the Underwriters sold Units to the person alleging
such loss, claim, liability, expense or damage without sending or giving, at or
prior to the written confirmation of such sale, a copy of the Prospectus (as
then amended or supplemented) if the Partnership had previously furnished copies
thereof to the Underwriters within a reasonable amount of time prior to such
sale or such confirmation, and the Underwriters failed to deliver the corrected
Prospectus, if required by law to have so delivered it and if delivered would
have been a complete defense against the person asserting such loss, claim,
liability, expense or damage. This indemnity agreement will be in addition to
any liability that the EOTT Entities might otherwise have.

                  (b) Each Underwriter, severally and not jointly, will
indemnify and hold harmless the EOTT Entities, each person, if any, who controls
the EOTT Entities within the meaning of Section 15 of the Act or Section 20 of
the Exchange Act, each director of the EOTT Entities and each officer of the
EOTT Entities who signed the Registration Statement to the same extent as the
foregoing indemnity from the EOTT Entities to each Underwriter, but only insofar
as losses, claims, liabilities, expenses, or damages arise out of or are based
on any untrue statement or omission or alleged untrue statement or omission of a
material fact made in reliance on and in conformity with information relating to
such Underwriter furnished in writing to the Partnership by such Underwriter
expressly for use in the Registration Statement or the Prospectus. 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.

                  (c) Any party that proposes to assert the right to be
indemnified under this Section 6 will, promptly after receipt of notice of
commencement of any action against such party in respect of which a claim is to
be made against an indemnifying party or parties under this Section 6, notify
each such indemnifying party of the commencement of such action, enclosing a
copy of all papers served, but the omission so to notify such indemnifying party
will not relieve it from any liability that it may have to any indemnified party
under the foregoing provisions of this Section 6 unless, and only to the extent
that, such omission results in the forfeiture of substantive rights or defenses
by the indemnifying party. If any such action is brought against any indemnified
party and it notifies the indemnifying party of its commencement, the
indemnifying party will be entitled to participate in and, to the extent that it
elects by delivering written notice to the indemnified party promptly after
receiving notice of the commencement of the action from the indemnified party,
jointly with any other indemnifying party similarly notified, to assume the
defense of the action, with counsel satisfactory to the indemnified party, and
after notice from the indemnifying party to the indemnified party of its
election to assume the defense, the indemnifying party will not be liable to the
indemnified party for any legal or other expenses except as provided below and
except for the reasonable costs of investigation subsequently incurred by the
indemnified party in connection with the defense. The indemnified party will
have the right to employ its own counsel in any such action, but the fees,
expenses and other charges of such counsel will be at the expense of such
indemnified party unless (1) the employment of counsel by the indemnified party
has been authorized in writing by the indemnifying party, (2) the indemnified
party has reasonably concluded (based on advice of




<PAGE>   21

counsel) that there may be legal defenses available to it or other indemnified
parties that are different from or in addition to those available to the
indemnifying party, (3) a conflict or potential conflict exists (based on advice
of counsel to the indemnified party) between the indemnified party and the
indemnifying party (in which case the indemnifying party will not have the right
to direct the defense of such action on behalf of the indemnified party) or (4)
the indemnifying party has not in fact employed counsel to assume the defense of
such action within a reasonable time after receiving notice of the commencement
of the action, in each of which cases the reasonable fees, disbursements and
other charges of counsel will be at the expense of the indemnifying party or
parties. It is understood that the indemnifying party or parties shall not, in
connection with any proceeding or related proceedings in the same jurisdiction,
be liable for the reasonable fees, disbursements and other charges of more than
one separate firm (in addition to local counsel) admitted to practice in such
jurisdiction at any one time for all such indemnified party or parties. All such
fees, disbursements and other charges will be reimbursed by the indemnifying
party promptly as they are incurred. An indemnifying party will not be liable
for any settlement of any action or claim effected without its written consent
(which consent will not be unreasonably withheld). No indemnifying party shall,
without the prior written consent of each indemnified party, settle or
compromise or consent to the entry of any judgment in any pending or threatened
claim, action or proceeding relating to the matters contemplated by this Section
6 (whether or not any indemnified party is a party thereto), unless such
settlement, compromise or consent includes an unconditional release of each
indemnified party from all liability arising or that may arise out of such
claim, action or proceeding.

                  (d) In order to provide for just and equitable contribution in
circumstances in which the indemnification provided for in the foregoing
paragraphs of this Section 6 is applicable in accordance with its terms but for
any reason is held to be unavailable from the EOTT Entities or the Underwriters,
the EOTT Entities and the Underwriters will contribute to the total losses,
claims, liabilities, expenses and damages (including any investigative, legal
and other expenses reasonably incurred in connection with, and any amount paid
in settlement of, any action, suit or proceeding or any claim asserted, but
after deducting any contribution received by the EOTT Entities from persons
other than the Underwriters, such as persons who control the EOTT Entities
within the meaning of the Act, officers of the EOTT Entities who signed the
Registration Statement and directors of the EOTT Entities, who also may be
liable for contribution) to which the EOTT Entities and any one or more of the
Underwriters may be subject in such proportion as shall be appropriate to
reflect the relative benefits received by the EOTT Entities on the one hand and
the Underwriters on the other. The relative benefits received by the EOTT
Entities on the one hand and the Underwriters on the other shall be deemed to be
in the same proportion as the total net proceeds from the offering (before
deducting expenses) received by the Partnership bear to the total underwriting
discounts and commissions received by the Underwriters, in each case as set
forth in the table on the cover page of the Prospectus Supplement. If, but only
if, the allocation provided by the foregoing sentence is not permitted by
applicable law, the allocation of contribution shall be made in such proportion
as is appropriate to reflect not only the relative benefits referred to in the
foregoing sentence but also the relative fault of the EOTT Entities, on the one
hand, and the Underwriters, on the other, with respect to the statements or
omissions which resulted in such loss, claim, liability, expense or damage, or
action in respect thereof, as well as any other relevant equitable
considerations with respect to such offering. Such relative



<PAGE>   22

fault shall be determined by reference to whether the untrue or alleged untrue
statement of a material fact or omission or alleged omission to state a material
fact relates to information supplied by the EOTT Entities or the Underwriters,
the intent of the parties and their relative knowledge, access to information
and opportunity to correct or prevent such statement or omission. The EOTT
Entities and the Underwriters agree that it would not be just and equitable if
contributions pursuant to this Section 6(d) were to be 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 into account
the equitable considerations referred to herein. The amount paid or payable by
an indemnified party as a result of the loss, claim, liability, expense or
damage, or action in respect thereof, referred to above in this Section 6(d)
shall be deemed to include, for purpose of this Section 6(d), any legal or other
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this Section 6(d), no Underwriter shall be required to contribute
any amount in excess of the underwriting discounts and commissions received by
it and no person found guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Act) will be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation. The
Underwriters' obligations to contribute as provided in this Section 6(d) are
several in proportion to their respective underwriting obligations and not
joint. For purposes of this Section 6(d), any person who controls a party to
this Agreement within the meaning of the Act will have the same rights to
contribution as that party, and each officer of the EOTT Entities who signed the
Registration Statement will have the same rights to contribution as the EOTT
Entities, subject in each case to the provisions hereof. Any party entitled to
contribution, promptly after receipt of notice of commencement of any action
against such party in respect of which a claim for contribution may be made
under this Section 6(d), will notify any such party or parties from whom
contribution may be sought, but the omission so to notify will not relieve the
party or parties from whom contribution may be sought from any other obligation
it or they may have under this Section 6(d). Except for a settlement entered
into pursuant to the last sentence of Section 6(c) hereof, no party will be
liable for contribution with respect to any action or claim settled without its
written consent (which consent will not be unreasonably withheld).

                  (e) The indemnity and contribution agreements contained in
this Section 6 and the representations and warranties of the EOTT Entities
contained in this Agreement shall remain operative and in full force and effect
regardless of (i) any investigation made by or on behalf of the Underwriters,
(ii) acceptance of the Units and payment therefore or (iii) any termination of
this Agreement.

         7. Termination. The obligations of the several Underwriters under this
Agreement may be terminated at any time on or prior to the Closing Date(or, with
respect to the Option Units, on or prior to the Option Closing Date), by notice
to the Partnership from the Underwriters, without liability on the part of any
Underwriter to the EOTT Entities, if, prior to delivery and payment for the Firm
Units (or the Option Units, as the case may be), the Underwriters shall decline
to purchase the Units for any reason permitted under this Agreement or, in the
sole judgment of the Underwriters, (i) there has been, since the respective
dates as of which information is given in the Registration Statement, any
material adverse change in any of the EOTT Entities' properties, business
prospects, condition (financial or otherwise) or results of



<PAGE>   23

operations, (ii) trading in any of the equity securities of the Partnership
shall have been suspended by the Commission, the NASD or by the New York Stock
Exchange, (iii) trading in securities generally on the New York Stock Exchange
or the Nasdaq Stock Market shall have been suspended or limited or minimum or
maximum prices shall have been generally established on such exchange or over
the counter market, or additional material governmental restrictions, not in
force on the date of this Agreement, shall have been imposed upon trading in
securities generally by such exchange or by order of the Commission or the NASD
or any court or other governmental authority, (iv) a general banking moratorium
shall have been declared by either Federal or New York State authorities or (v)
any material adverse change in the financial or securities markets in the United
States or in political, financial or economic conditions in the United States or
any outbreak or material escalation of hostilities or declaration by the United
States of a national emergency or war or other calamity or crisis shall have
occurred the effect of any of which is such as to make it, in the sole judgment
of the Underwriters, impracticable or inadvisable to market the Units on the
terms and in the manner contemplated by the Prospectus.

         8. Substitution of Underwriters. If any one or more of the Underwriters
shall fail or refuse to purchase any of the Firm Units which it or they have
agreed to purchase hereunder, and the aggregate number of Firm Units which such
defaulting Underwriter or Underwriters agreed but failed or refused to purchase
is not more than one-tenth of the aggregate number of Firm Units, the other
Underwriters shall be obligated, severally, to purchase the Firm Units which
such defaulting Underwriter or Underwriters agreed but failed or refused to
purchase, in the proportions which the number of Firm Units which they have
respectively agreed to purchase pursuant to Section 1 bears to the aggregate
number of Firm Units which all such non-defaulting Underwriters have so agreed
to purchase, or in such other proportions as such non-defaulting Underwriters
may specify; provided that in no event shall the maximum number of Firm Units
which any Underwriter has become obligated to purchase pursuant to Section 1 be
increased pursuant to this Section 8 by more than one-ninth of the number of
Firm Units agreed to be purchased by such Underwriter without the prior written
consent of such Underwriter. If any Underwriter or Underwriters shall fail or
refuse to purchase any Firm Units and the aggregate number of Firm Units which
such defaulting Underwriter or Underwriters agreed but failed or refused to
purchase exceeds one-tenth of the aggregate number of the Firm Units and
arrangements satisfactory to the non-defaulting Underwriters and the Partnership
for the purchase of such Firm Units are not made within 48 hours after such
default, this Agreement will terminate without liability on the part of any
non-defaulting Underwriter or the Partnership for the purchase or sale of any
Units under this Agreement. In any such case either the Underwriters or the
Partnership shall have the right to postpone the Closing Date, but in no event
for longer than seven days, in order that the required changes, if any, in the
Registration Statement and in the Prospectus or in any other documents or
arrangements may be effected. Any action taken pursuant to this Section 8 shall
not relieve any defaulting Underwriter from liability in respect of any default
of such Underwriter under this Agreement.

         9. Miscellaneous. Notice given pursuant to any of the provisions of
this Agreement shall be in writing and, unless otherwise specified, shall be
mailed or delivered (a) if to the EOTT Entities, at the office of 1330 Post Oak
Boulevard, Suite 2700, Houston, Texas 77002, Attention: Steve Duffy or (b) if to
the Underwriters, at the offices of PaineWebber Incorporated,




<PAGE>   24

1285 Avenue of the Americas, New York, New York 10019, Attention: Corporate
Finance Department. Any such notice shall be effective only upon receipt. Any
notice under Section 7 or 8 hereof may be made by telex or telephone, but if so
made shall be subsequently confirmed in writing.

         This Agreement has been and is made solely for the benefit of the
several Underwriters, the EOTT Entities and of the controlling persons,
directors and officers referred to in Section 6, and their respective successors
and assigns, and no other person 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 any of
the several Underwriters.

         All representations, warranties and agreements of the EOTT Entities
contained herein or in certificates or other instruments delivered pursuant
hereto, shall remain operative and in full force and effect regardless of any
investigation made by or on behalf of any Underwriter or any of its controlling
persons and shall survive delivery of and payment for the Units hereunder.

         Any action required or permitted to be taken by the Underwriters under
this Agreement may be taken by them jointly or by PaineWebber Incorporated.

         THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH
THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO THE CONFLICT OF LAWS
PRINCIPLES OF SUCH STATE.

         This Agreement may be signed in two or more counterparts with the same
effect as if the signatures thereto and hereto were upon the same instrument.

         In case any provision in this Agreement shall be invalid, illegal or
unenforceable, the validity, legality and enforceability of the remaining
provisions shall not in any way be affected or impaired thereby.

         The EOTT Entities and the Underwriters each hereby irrevocably waive
any right they may have to a trial by jury in respect of any claim based upon or
arising out of this Agreement or the transactions contemplated hereby.

         This Agreement may not be amended or otherwise modified or any
provision hereof waived except by an instrument in writing signed by the EOTT
Entities and the Underwriters.

         Please confirm that the foregoing correctly sets forth the agreement
among the EOTT Entities and the several Underwriters.


                                                     Very truly yours,

                                                     EOTT ENERGY PARTNERS, L.P.

Dear Sirs:

           In consideration of the agreement of the several Underwriters to
underwrite a proposed public offering (the "Offering") of 3,500,000 Common
Units (the "Common Units") of EOTT Energy Partners, L.P., a Delaware limited

with respect to such Common Units filed with the Securities and Exchange
Commission on Form S-3 (Registration No. 333-82269), the undersigned hereby
agrees that the undersigned will not, for a period of 90 days after the
commencement of the public offering of such Units, without the prior written
consent of PaineWebber Incorporated, (i) directly or indirectly, sell, offer to
sell, grant any option for the sale of, or otherwise dispose of, any Common
Units, units representing subordinated limited partner interests ("Subordinated
Units") or securities convertible into Common Units other than pursuant to
employee option plans, (ii) enter into any swap or other arrangement that
transfers to another, in whole or in part, any of the economic consequences of
ownership of the Common Units or Subordinated Units, whether any such
transaction described in clause (i) or (ii) above is to be settled by delivery
of Common Units, Subordinated Units or such other securities, in cash or
otherwise or (iii) require the Partnership to file with the Securities and
Exchange Commission a registration statement under the Securities Act of 1933

Ladies and Gentlemen:

                  (l) such other documents and records as we have deemed
         necessary or advisable for purposes of the opinions expressed below.

         Based on the foregoing, and subject to the qualifications and
limitations set forth below, we are of the opinion that:


<PAGE>   37

                  (1) Each of the Partnership and the Operating Partnerships
         has been duly formed and is validly existing and in good standing as a
         limited partnership under the Delaware Revised Uniform Limited
         Partnership Act, as amended (the "Delaware Act"), with partnership
         power and authority under the Delaware Act and the Partnership
         Agreement or its Operating Partnership Agreement, respectively,
         necessary to own, lease and operate its properties and conduct its
         business as described in the Prospectus.

                  (2) The Partnership has been registered as a foreign limited
         partnership for the transaction of business under the laws of each
         jurisdiction in which the failure to so register would have a material
         adverse effect upon the Partnership or subject it to any material
         liability or disability.

                  (3) Energy OLP has been qualified or registered as a foreign
         limited partnership for the transaction of business under the laws of
         each jurisdiction in which the failure to so register would have a
         material adverse effect upon Energy OLP or subject it to any material
         liability or disability; Pipeline OLP has been qualified or registered
         as a foreign limited partnership for the transaction of business under
         the laws of each jurisdiction in which the failure to so register
         would have a material adverse effect upon Pipeline OLP or subject it
         to any material liability or disability; and Canada OLP has been
         qualified or registered as a foreign limited partnership for the
         transaction of business under the laws of each jurisdiction in which
         the failure to so register would have a material adverse effect upon
         Canada OLP or subject it to any material liability or disability.

                  (4) Each of the General Partner and Finance Sub has been duly
         incorporated and is validly existing as a corporation in good standing
         under the laws of the State of Delaware, with corporate power and
         authority necessary to own, hold or lease its properties and, in all
         material respects as described in the Prospectus, to conduct the
         business in which it is engaged and, in the case of the General
         Partner, to act as a general partner of the Partnership and each of
         the Operating Partnerships. The General Partner is duly qualified to
         do business and is in good standing as a foreign corporation under the
         laws of each jurisdiction in which the failure to so register would
         have a material adverse effect upon the General Partner or subject it
         to any material liability or disability, and Finance Sub has not been
         qualified to do business as a foreign corporation under any
         jurisdiction.

                  (5) The General Partner is the sole general partner of the
         Partnership and each of the Operating Partnerships with a general
         partner interest in the Partnership of 1.0% and a general partner
         interest in each of the Operating Partnerships of 1.0% (subject to the
         provisions of the Partnership Agreement and the Operating Partnership
         Agreements, respectively); such general partner interests are duly
         authorized by the Partnership Agreement and the Operating



<PAGE>   38

         Partnership Agreements, respectively, are validly issued and are owned
         of record by the General Partner free and clear of all liens,
         encumbrances, security interests, equities, charges or claims of
         record (except as provided in the Partnership Agreement, the Operating
         Partnership Agreements or pursuant to Section 17-607 of the Delaware
         Act, as amended) (A) in respect of which a financing statement under
         the Uniform Commercial Code of the State of Delaware naming the
         General Partner as debtor is on file in the offices of the Secretary
         of State of the State of Delaware or (B) otherwise known to us.

                  (6) To our knowledge, the only subsidiaries (as defined in
         the Rules and Regulations) of the Partnership are the Operating
         Partnerships and the Finance Sub. All of the outstanding shares of
         capital stock of the Finance Sub have been duly authorized and validly
         issued and are fully paid and nonassessable and are owned by the
         Partnership free and clear of all liens and encumbrances and claims.
         As of the Closing Date, the Partnership is the sole limited partner of
         Energy OLP, and Energy OLP is the sole limited partner of Pipeline OLP
         and Canada OLP, in each case with a limited partner interest of 99.0%
         (subject to the provisions of the respective Operating Partnership
         Agreements); each such limited partner interest is duly authorized by
         the applicable Operating Partnership Agreement and is validly issued,
         fully paid and nonassessable, except as such nonassessability may be
         affected by Section 17-607 of the Delaware Act; and, at the Closing
         Date, the Partnership or Energy OLP, as the case may be, owns such
         limited partner interest in the Operating Partnership free and clear
         of all liens, encumbrances, security interests, equities, charges or
         claims of record (except as provided in the applicable Operating
         Partnership Agreement or pursuant to the Delaware Act) (A) in respect
         of which a financing statement under the Uniform Commercial Code of
         the State of Delaware naming the Partnership as debtor is on file in
         the offices of the Secretary of State of the State of Delaware or (B)
         otherwise known to us. Except for such limited partner interests and
         the stock of the Finance Sub, the Partnership does not, to our
         knowledge, own at the Closing Date, directly or indirectly, any shares
         of stock or any other equity or long-term debt securities of any
         corporation or have any equity interest in any firm, partnership,
         joint venture, association or other entity.

                  (7) Immediately prior to the Closing Date, the limited
         partners of the Partnership hold limited partner interests in the
         Partnership aggregating 99.0% (subject to the provisions of the
         Partnership Agreement), such limited partner interests being
         represented by 14,976,011 Common Units and 9,000,000 Subordinated
         Units. As of the Closing Date, such limited partner interests are the
         only limited partner interests of the Partnership that are issued and
         outstanding. As of the Closing Date, the Units are authorized by the
         Partnership Agreement and are validly issued, fully paid and
         nonassessable, except as such nonassessability may be affected by
         Section 17-607 of the Delaware Act.


<PAGE>   39

                  (8) Insofar as such descriptions relate to legal matters or
         descriptions of provisions of the governing instruments, the Common
         Units and the Subordinated Units conform in all material respects to
         the descriptions thereof contained in the Prospectus.

                  (9) Except as described in the Prospectus or Section 4.3 of
         the Partnership Agreement and except for the Underwriters'
         over-allotment option, there are no preemptive or other rights to
         subscribe for or to purchase, nor any restriction upon the voting or
         transfer of, any limited partner interests of the Partnership or any
         of the Operating Partnerships pursuant to (i) the statutes, judicial
         and administrative decisions, and the rules and regulations of the
         governmental agencies of the State of Delaware, (ii) the Partnership
         Agreements or (iii) any agreement, document, contract or instrument
         referred to in, filed as an exhibit to or incorporated by reference
         in, the Registration Statement.

                  (10) To our knowledge, and other than as set forth in or
         contemplated by the Prospectus, there are no legal or governmental
         proceedings pending or threatened (i) to which any of the EOTT
         Entities is a party or of which any property of any of such entities
         is the subject, or to which any of their officers or directors in
         their capacities as such is a party, which, if adversely determined to
         such entity, might have a material adverse effect on the consolidated
         financial position, results of operations, cash flows, business or
         prospects of the Partnership and the Operating Partnerships considered
         as a whole or (ii) which seek to challenge to legality or
         enforceability of the Underwriting Agreement.

                  (11) The Registration Statement was declared effective under
         the Act on September 2, 1999; the Prospectus was filed with the
         Commission pursuant to subparagraphs (2) and (5) of Rule 424(b) of the
         Rules and Regulations on September [ ], 1999; and no stop order
         suspending the effectiveness of the Registration Statement has been
         issued, and no proceeding for that purpose is pending or, to our
         knowledge, threatened by the Commission.

                  (12) The Registration Statement and the Prospectus, including
         any documents incorporated by reference into the Prospectus, at the
         time they were filed (other than the financial statements and related
         schedules or other financial or statistical data and the projected
         data included therein, as to which we express no opinion) comply or
         complied as to form in all material respects with the requirements of
         the Act, the Rules and Regulations, the Exchange Act, and the Exchange
         Act Rules and Regulations.

                  (13) To our knowledge, there are no contracts or other
         documents that are required to be summarized or described in the
         Prospectus or filed as exhibits or incorporated by reference into to
         the Registration Statement by the Act or by the rules and regulations
         of the Commission thereunder that have not been summarized or
         described in all material respects in the Prospectus or filed as
         exhibits to the Registration Statement or incorporated by reference
         therein.


<PAGE>   40

                  (14) The statements contained in the Prospectus under the
         caption "Tax Considerations," insofar as they describe federal
         statutes, rules and regulations, constitute a fair summary thereof
         that is accurate in all material respects; our opinion filed as
         Exhibit 8 to the Registration Statement is confirmed; and the
         Underwriters may rely upon such opinion as if it were addressed to
         them.

                  (15) The Underwriting Agreement has been duly authorized,
         executed and delivered by each of the EOTT Entities.

                  (16) The execution and delivery by each of the EOTT Entities
         of the Underwriting Agreement, and the compliance by each of the EOTT
         Entities with all of the provisions of the Underwriting Agreement do
         not and will not, with the passage of time or upon stated contingency
         or otherwise, (i) conflict with or result in a breach or violation of
         any of the terms or provisions of, or constitute a default under, (x)
         any indenture, mortgage, deed of trust, loan agreement, bond,
         debenture, note agreement, capital lease or other evidence of
         indebtedness for borrowed money, of which we have knowledge, to which
         any of the EOTT Entities is a party or by which any EOTT Entity is
         bound or to which any property or assets of any EOTT Entity is
         subject, (y) any contract or other agreement to which any of the EOTT
         Entities is a party that restricts the ability of the Partnership to
         issue securities and of which we have knowledge or (z) any document
         filed as an exhibit to, or incorporated by reference in, the
         Registration Statement, (ii) result in any breach or violation of the
         provisions of the agreement or certificate of limited partnership or
         articles of incorporation or bylaws of any such entity or (iii) result
         in any breach or violation of any statute or any rule or regulation of
         any governmental agency or body having jurisdiction over any such
         entity or its properties that a lawyer exercising customary
         professional diligence would reasonably recognize as being directly
         applicable to the Partnership, any of the Operating Partnerships or
         the General Partner or to the transactions contemplated by the
         Underwriting Agreement, or to both, excluding in each case any
         breaches or violations which, individually or in the aggregate, would
         not have a material adverse effect on the limited partners or the
         financial condition, results of operation, business or prospects (as
         described in the Prospectus) of the Partnership and the Operating
         Partnerships considered as a whole.

                  (17) Except as described in the Prospectus or Section 6.13 of
         the Partnership Agreement and except for the registration rights
         referred to in Section 4(o) of the Underwriting Agreement, to our
         knowledge there are no contracts, agreements or understandings between
         the Partnership, the Operating Partnerships or the General Partner and
         any person granting such person the right to require the Partnership
         to file a registration statement under the Act with



<PAGE>   41

         respect to any securities of the Partnership or to require the
         Partnership to include such securities in the securities to be
         registered pursuant to the Registration Statement or in any securities
         being registered pursuant to any other registration statement filed by
         the Partnership under the Act.

                  (18) Neither the Partnership nor any of the Operating
         Partnerships is an "investment company" or an "affiliated person" of,
         or "promoter" or "principal underwriter" for, an "investment company,"
         as such terms are defined in the Investment Company Act and the rules
         and regulations thereunder, and the General Partner is either (A) not
         an "investment company"or an "affiliated person" of, or "promoter" or
         "principal underwriter" for, an "investment company," as such terms
         are defined in the Investment Company Act and the rules and
         regulations thereunder or (B) exempt from the Investment Company Act.

                  (19) None of the Partnership, the Operating Partnerships or
         the General Partner is a "public utility company," a "holding company"
         or an "affiliate" of a holding company or a public utility company
         within the meaning of the Public Utility Holding Company Act of 1935,
         as amended.

                  (20) No consent, approval, authorization, order, registration
         or qualification of or with any federal governmental agency or body or
         any governmental agency or body of the States of Texas, New York or
         Delaware is required for the sale of the Common Units or the execution
         and delivery of the Underwriting Agreement and the consummation by any
         of the EOTT Entities of the transactions contemplated by the
         Underwriting Agreement and the Prospectus, except (1) such consents,
         approvals, authorizations, orders, registrations or qualifications (a)
         as have been obtained, (b) as may be required under the Act or state
         securities or Blue Sky laws, (c) as are of a routine or administrative
         nature and either are (i) not customarily obtained or made prior to
         the consummation of similar transactions or (ii) expected in our
         reasonable judgment to be obtained in the ordinary course of business
         subsequent to the consummation of the transactions, or (d) which, if
         not obtained, would not, individually or in the aggregate, have a
         material adverse effect upon the ability of the Partnership and the
         Operating Partnerships taken as a whole to conduct their business as
         described in the Prospectus, or (2) as described, set forth or
         contemplated in the Prospectus as not having been obtained.

                  (21) (i) The Partnership Agreement is a valid and legally
         binding agreement of the General Partner, enforceable against the
         General Partner in accordance with its terms and (ii) each of the
         Operating Partnership Agreements is a valid and legally binding
         agreement of such parties, enforceable against the General Partner and
         the Partnership in accordance with its terms, subject to the
         qualifications that (A) the enforceability of each such agreement may
         be limited by bankruptcy, insolvency, fraudulent transfer,
         reorganization, moratorium and


<PAGE>   42

         other similar laws of general applicability relating to or affecting
         the rights of creditors generally, (B) the enforceability of each such
         agreement may be limited by public policy, applicable law relating to
         fiduciary duties and the judicial imposition of an implied covenant of
         good faith and fair dealing, (C) the enforceability of equitable
         rights and remedies provided for in each such agreement is subject to
         equitable defenses and judicial discretion, and (D) the enforceability
         of certain other provisions of each such agreement may be limited by
         applicable laws and court decisions, none of which should materially
         and adversely interfere with the practical realization of the material
         benefits intended to be provided by such agreements.

                  (22) The Firm Units and the Optional Units are duly
         authorized for listing, subject only to official notice of issuance,
         on the New York Stock Exchange.

                  (23) The descriptions (i) in "Item 1. Business --
         Environmental Matters" and "Item 1. Business -- Regulation" from the
         Partnership's Annual Report on Form 10-K for the year ended December
         31, 1998 and (ii) under "Cash Distribution Policy" and "Description of
         Our Partnership Agreement" in the Prospectus, insofar as such
         descriptions relate to legal matters or descriptions of the provisions
         of the Partnership Agreement, are accurate and fairly present the
         information required to be shown.

                  The opinions expressed herein are qualified in the following
         respects:

                  (A) We have relied, without independent investigation or
         verification, in respect of factual matters upon certificates of
         officers of the General Partner and upon information obtained from
         public officials, upon opinions of other counsel issued in connection
         with the transactions (copies of which have been furnished to you and
         your counsel) and other sources believed by us to be responsible.

                  (B) We have assumed, without independent verification, that
         the certificates for the Common Units conform to the specimens thereof
         examined by us and have been duly countersigned by a transfer agent
         and duly registered by a registrar of the Common Units.

                  (C) We express no opinion with respect to state or local
         taxes or tax statutes to which any of the Partnership, the limited
         partners, any of the Operating Partnerships, or General Partner may be
         subject.

                  (D) For purposes of the foregoing opinions, we have conducted
         such investigation as in our judgment is necessary to enable us to
         render the foregoing opinions. References herein to our knowledge
         shall mean the actual knowledge of our attorneys substantially
         participating in the work of this firm as



<PAGE>   43

         counsel with respect to the matters relating to the transactions and
         without in any manner having conducted any investigation other than as
         described herein.

                  (E) We have assumed that (a) each document submitted to us
         for review is accurate and complete, each such document that is an
         original is authentic, each such document that is a copy conforms to
         an authentic original and all signatures on each such document are
         genuine, (b) each certificate from governmental officials reviewed by
         us is accurate, complete and authentic, and all official public
         records are accurate and complete, (c) all parties to the Underwriting
         Agreement will act in accordance with, and will refrain from taking
         any action that is forbidden by, the terms and conditions of the
         Underwriting Agreement, and (d) no party to the Underwriting Agreement
         will in the future take any discretionary action (including a decision
         not to act) permitted under the Underwriting Agreement that would
         result in a violation of law or constitute a breach or default under
         any other agreement to which such party is a party or by which it or
         its property is bound or under any court or administrative order,
         writ, judgment or decree that names such party or is directed to it or
         its property.

                  (F) This opinion is limited in all respects to federal laws,
         the Delaware Act, the Delaware General Corporation Law, the laws of
         the States of New York and Texas (excluding rules, regulations and
         ordinances of counties, towns, municipalities and other special
         political subdivisions of the States of New York and Texas).

                  (G) In giving the opinion expressed in paragraph (19) above,
         we have relied upon certificates from authorized officers of the
         General Partner, dated as of recent dates.

         Since we have not conducted any independent investigation with regard
to the information set forth in the Registration Statement or Prospectus
(except with respect to the opinions set forth herein), we are not (except as
aforesaid) passing upon and do not assume any responsibility for the accuracy,
completeness or fairness of the statements contained therein. We have
participated, however, in conferences with officers and other representatives
of the General Partner, representatives of the independent public accountants
of the General Partner and your representatives, at which the contents of the
Registration Statement and Prospectus and related matters were discussed. On
the basis of the foregoing (relying, as to materiality, to the extent we deem
appropriate upon the opinions of the officers and other representatives of the
General Partner), we advise you that no facts have come to our attention that
have led us to believe that the Registration Statement, at the time such
Registration Statement became effective, contained any untrue statement of a
material fact or omitted to state a material fact required to be stated therein
or necessary to make the statements therein not misleading


<PAGE>   44

or that, as of its date, the Prospectus contained an untrue statement of a
material fact or omitted a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading or that, as of the date hereof, either the
Registration Statement contains an untrue statement of a material fact or omits
to state a material fact necessary to make the statements therein not
misleading or the Prospectus contains an untrue statement of a material fact or
omits to state a material fact necessary to make the statements therein, in
light of the circumstances under which they were made, not misleading. We
express no comment with respect to the financial statements and related
schedules and other financial data included or incorporated by reference in the
Registration Statement or in the Prospectus or any further amendment or
supplement thereto (including, without limitation, statements relating to
projected cash distributions to the limited partners) or any statement
contained therein or omitted therefrom in reliance upon and in conformity with
written information furnished to the Partnership by any Underwriter through you
expressly for use therein.

         This opinion is furnished to the several Underwriters and is solely
for the benefit of the several Underwriters in connection with the transactions
contemplated by the Underwriting Agreement and may not be relied upon in
connection with any other transaction or by any other person or entity or
furnished to anyone else without the prior written consent of the undersigned.

                                   Very truly yours,

PAINEWEBBER INCORPORATED

ING BARINGS LLC
c/o PaineWebber Incorporated

New York, New York  10019

Ladies and Gentlemen:

         This opinion is provided to you pursuant to Section 5(g) of that
certain Underwriting Agreement, dated September 23, 1999 (the "Underwriting
Agreement"), among EOTT Energy Partners, L.P., a Delaware limited partnership
(the "Partnership"), EOTT Energy Operating Limited Partnership, a Delaware
limited partnership ("Energy OLP"), EOTT Energy Pipeline Limited Partnership, a
Delaware limited partnership ("Pipeline OLP"), EOTT Energy Canada Limited
Partnership, a Delaware limited partnership ("Canada OLP"), EOTT Energy Corp.,
a Delaware corporation (the "General Partner"), and PaineWebber Incorporated,
Lehman Brothers Inc., Dain Rauscher Wessels, a Division of Dain Rauscher
Incorporated, and ING Barings LLC (the "Underwriters"). Any capitalized term
used in this opinion and not defined shall have the meaning assigned to such
term in the Underwriting Agreement. This opinion is being provided for the
closing contemplated by the Underwriting Agreement of the offer and sale of the
Firm Units (the "Closing Date").

         I am Vice President and General Counsel of the General Partner, and I
have worked with the law firm of Vinson & Elkins in connection with its role as
counsel for the General Partner in connection with the offer and sale by the
Partnership of 3,500,000 Firm Units. In connection with the opinions expressed
below, I have examined such documents and records and consulted such other
sources as I have deemed necessary or advisable for purposes of the opinions
expressed below. Based on the foregoing and subject to the qualifications and
limitation set forth below, I am of the opinion that:

         1. To my knowledge, each of the EOTT Entities is operating in
compliance, in all material respects, with all certificates, authorizations or
permits which have been issued by local, state, federal or foreign regulatory
agencies or bodies in connection with the business currently being operated by
it. To my knowledge, there are no certificates, authorizations or permits which
have not been obtained for any such business, where the absence of same could,
in my opinion, reasonably be expected to have, individually or in the
aggregate, a material adverse effect upon the ability of the EOTT Entities to
conduct




<PAGE>   46

their businesses in all material respects as currently conducted, and, except
as disclosed in the Prospectus, the EOTT Entities have not, to my knowledge,
received any notice of proceedings relating to the revocation or modification
of any certificate, authorization or permit which, singly or in the aggregate,
if the subject of an unfavorable decision, ruling or finding, could, in my
opinion, reasonably be expected to have a material adverse effect upon the
ability of the EOTT Entities to conduct their businesses in all material
respects as currently conducted, and as described in the Prospectus.

         2. Except as set forth to in the Prospectus, there are, to my
knowledge, no legal or governmental proceedings pending or threatened to which
any of the EOTT Entities is a party or of which any property of the EOTT
Entities is the subject which, if determined adversely, could, in my opinion,
be reasonably expected to have a material adverse effect on the consolidated
financial position, results of operations, cash flows, business or prospects of
the EOTT Entities.

         3. To my knowledge, and except as otherwise set forth in the
Prospectus, the consummation of the transactions contemplated in the
Underwriting Agreement and in the Prospectus will not, with the passage of time
or upon a stated contingency or otherwise, conflict with or result in a breach
or violation of any of the terms or provisions of, or constitute a default
under, any indenture, mortgage, deed of trust, loan agreement or other
agreement or instrument to which any of the EOTT Entities is a party or by
which any EOTT Entity is bound or to which any property or assets of any EOTT
Entity is subject, nor, to my knowledge, will such actions result in any
violation of the provisions of the Partnership Agreement or any statute or any
order, rule or regulation of any court or governmental agency or body having

excluding, in each case, any breach(es) or violation(s) which, individually or
in the aggregate, could not be reasonably expected to have a material adverse
effect on the limited partners or the financial condition, results of
operation, business or prospects (as described in the Prospectus) of the EOTT
Entities, considered as a whole.

         The opinions expressed herein are qualified in the following respect:
I have relied, without independent investigation or verification, in respect of
certain factual matters upon information obtained from public officials and
other sources believed by me to be responsible.

         Since I have not conducted any independent investigation with regard
to the information set forth in the Registration Statement or Prospectus, I am
not (except as expressly set forth above), passing upon and do not assume any
responsibility for the accuracy, completeness or fairness of the statements
contained therein. In addition to the foregoing opinions, however, I hereby
advise you that during the course of my representation of the EOTT Entities no
facts have come to my attention that have led me to believe that the
Registration Statement, at the time such Registration Statement or any
amendments thereto became effective prior to the date hereof, contained any
untrue statement of a material fact or omitted to state a material fact
required to be stated therein

or necessary to make the statements therein not misleading, or that, as of its
date, the Prospectus or any further amendment or supplement thereto made prior
to the date hereof contained an untrue statement of a material fact or omitted
a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading, or that, as of the date hereof, either the Registration
Statement or any further amendment thereto made prior to the date hereof,
contains an untrue statement of a material fact or omits to state a material
fact necessary to make the statements therein, in light of the circumstances
under which they were made, not misleading or the Prospectus or any further
supplement thereto made prior to the date hereof, contains an untrue statement
of a material fact or omits to state a material fact necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading. The foregoing notwithstanding, I express no comment with
respect to the financial statements and related schedules and other financial
data included or incorporated by reference in the Registration Statement or in
the Prospectus or any further amendment or supplement thereto (including,
without limitation, statements relating to income, profits, cash flows and
projected cash distributions to the limited partners of the Partnership) or any
statement contained therein or omitted therefrom in reliance upon and in
conformity with written information furnished to the Partnership by you
expressly for use therein.

         This opinion is furnished to the several underwriters and is solely
for the benefit of the several underwriters in connection with the transactions
contemplated by the Underwriting Agreement and may not be relied upon in
connection with any other transaction or by any other person or entity or
