Dear Sirs:

     Valero L.P., a Delaware limited partnership (the  "Partnership"),  proposes
to issue and sell to Lehman Brothers Inc., as underwriter  (the  "Underwriter"),
1,075,000 Common Units (the "Firm Units"),  each  representing a limited partner
interest in the Partnership (the "Common Units").  In addition,  the Partnership
proposes to grant to the  Underwriter  an option to purchase up to an additional
161,250  Common Units,  on the terms and for the purposes set forth in Section 2
(the "Option  Units").  The Firm Units and the Option Units,  if purchased,  are
hereinafter collectively called the "Units."

     This  is  to  confirm  the  agreement  among  the  Partnership,   Riverwalk
Logistics,  L.P., a Delaware limited  partnership and the general partner of the
Partnership  (the  "General  Partner"),  Valero  GP,  LLC,  a  Delaware  limited
liability  company  ("Valero GP"), an indirect wholly owned subsidiary of Valero
Energy Corporation,  a Delaware corporation  ("Valero Energy"),  and the general
partner of the General Partner,  Valero Logistics  Operations,  L.P., a Delaware
limited  partnership  (the  "Operating  Partnership"),  and Valero GP,  Inc.,  a
Delaware  corporation,  a direct wholly owned  subsidiary of the Partnership and
the general  partner of the Operating  Partnership  (the "OLP General  Partner")
(collectively,  the "Partnership  Parties"),  and the Underwriter concerning the
purchase  of the Firm Units and the Option  Units  from the  Partnership  by the
Underwriter.  The  Partnership  Parties  and  Skelly-Belvieu  Pipeline  Company,
L.L.C.,  a  Delaware  limited  liability  company  ("Skelly-Belvieu  LLC"),  are
hereinafter referred to collectively as the "Partnership Entities."

     1.  Representations,  Warranties and Agreements of the Partnership Parties.
Each of the Partnership Parties represents and warrants to, and agrees with, the
Underwriter that:

     (a)  Definitions.  The  Partnership  and  the  Operating  Partnership  have
prepared  and  filed  with  the   Securities   and  Exchange   Commission   (the
"Commission")  in accordance  with the provisions of the Securities Act of 1933,
as amended (the  "Securities  Act"), a registration  statement on Form S-3 under
the  Securities  Act  (Commission   File  No.   333-89978)  (the   "registration
statement"), including a prospectus subject to completion relating to the Units.
Such registration  statement has been declared effective by the Commission.  The
term  "Registration  Statement" as used in this Agreement means the registration
statement  (including all financial schedules and exhibits),  as supplemented or
amended prior to the execution of this Agreement. If it is contemplated,  at the
time  this  Agreement  is  executed,  that  a  post-effective  amendment  to the
registration  statement will be filed and must be declared  effective before the
offering of the Units may commence, the term "Registration Statement" as used in
this   Agreement   means  the   registration   statement   as  amended  by  said
post-effective  amendment. If it is contemplated,  at the time this Agreement is
executed,  that a registration  statement or a post-effective  amendment will be
filed pursuant to Rule 462(b) or Rule 462(d) under the Securities Act before the
offering of the Units may commence, the term "Registration Statement" as used in
this Agreement includes such registration statement. The term "Basic Prospectus"
as used in this  Agreement  means the  prospectus  in the form  included  in the
Registration  Statement at the time that the Registration Statement was declared
effective  or in the  form in which it has been  most  recently  filed  with the
Commission on or prior to the date of this  Agreement.  "Prospectus"  shall mean
the prospectus supplement relating to the Units and the offering thereof that is
first filed  pursuant to Rule 424(b) under the  Securities  Act ("Rule  424(b)")
after the date and time this  Agreement is executed and delivered by the parties
hereto, together with the Basic Prospectus. The term "Preliminary Prospectus" as
used in this Agreement  means any prospectus  relating to the Units that omitted
information  to be included upon pricing in a form of prospectus  filed with the
Commission  pursuant to Rule 424(b) under the  Securities Act and was used after
such  effectiveness  and prior to the initial  delivery of the Prospectus to the
Underwriter.

                                       2


     (b) Financial Statements and Schedules. All references in this Agreement to
financial  statements and schedules and other  information which is "contained,"
"included" or "stated" in the Registration  Statement,  the Basic Prospectus,  a
Preliminary  Prospectus or the Prospectus  (or other  references of like import)
shall be deemed to mean and include all such financial  statements and schedules
and other  information  which is incorporated  by reference in the  Registration
Statement, the Basic Prospectus, a Preliminary Prospectus or the Prospectus,  as
the case may be; any reference in this Agreement to the Registration  Statement,
the Basic Prospectus, a Preliminary Prospectus 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  under  the  Securities  Act,  as of the  date of the
Registration Statement, the Basic Prospectus,  the Preliminary Prospectus or the
Prospectus, as the case may be; and any reference to any amendment or supplement
to the Registration Statement, the Basic Prospectus,  any Preliminary Prospectus
or the  Prospectus  shall be deemed to refer to and include any documents  filed
after such date  under the  Securities  Exchange  Act of 1934,  as amended  (the
"Exchange Act"),  which, upon filing, are incorporated by reference therein,  as
required  by  paragraph  (b) of Item 12 of Form S-3.  As used  herein,  the term
"Incorporated  Documents" means the documents which at the time are incorporated
by  reference  in  the  Registration  Statement,   the  Basic  Prospectus,   any
Preliminary Prospectus or the Prospectus or any amendment or supplement thereto.

     (c) No Stop  Order.  No stop  order  suspending  the  effectiveness  of the
Registration  Statement has been issued and, to the knowledge of the Partnership
Parties,  no proceeding for that purpose has been initiated or threatened by the
Commission.  The  Registration  Statement  and the  Prospectus,  and any further
amendments or supplements to the  Registration  Statement or the Prospectus,  do
not and will not, as of the  applicable  effective  date as to the  Registration
Statement and any amendment thereto, and as of the applicable filing date and on
each Delivery Date as to the Prospectus and any amendment or supplement thereto,
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  statements  therein not
misleading;  provided,  however, that this representation and warranty shall not
apply to any  statements  or omissions  made in reliance  upon and in conformity
with  information  furnished  in writing  to the  Operating  Partnership  or the
Partnership  by the  Underwriter  expressly  for use  therein;  and  each of the
statements  made  by  the  Partnership  or  the  Operating  Partnership  in  the
Registration  Statement,  and to be  made  in the  Prospectus  and  any  further
amendments or supplements to the Registration Statement or Prospectus within the
coverage of Rule 175(b) of the rules and regulations of the Commission under the
Securities Act (the "Rules and Regulations"), including (but not limited to) any
statements with respect to future available cash or future cash distributions or
earnings of the  Partnership  or the Operating  Partnership  or the  anticipated
ratio of  taxable  income  to  distributions,  was  made or will be made  with a
reasonable basis and in good faith.

     (d) Incorporated  Documents.  The Incorporated  Documents heretofore filed,
when they were filed (or, if any amendment with respect to any such document was
filed,  when such amendment was filed),  conformed in all material respects with
the  requirements  of the Exchange  Act; any further  Incorporated  Documents so
filed  will,  when they are filed,  conform in all  material  respects  with the
requirements  of the Exchange Act; no such document when it was filed (or, if an
amendment  with respect to any such document was filed,  when such amendment was
filed),  contained an untrue  statement of a material fact or omitted to state a
material  fact  required to be stated  therein or necessary in order to make the
statements  therein not  misleading;  and no such further  document,  when it is
filed, will contain an untrue statement of a material fact or will omit to state
a material fact required to be stated  therein or necessary in order to make the
statements therein not misleading.

and occupy the pipeline rights-of-way as they have been used and occupied in the
past  and  are to be  used  and  occupied  in the  future  as  described  in the

regulatory authorities ("permits") as are necessary to own its properties and to
conduct its business in the manner described in the Prospectus,  subject to such
qualifications as may be set forth in the Prospectus and except for such permits
which,  if not obtained,  would not,  individually  or in the aggregate,  have a
Material  Adverse  Effect;  each of the  Partnership  Entities has fulfilled and
performed,  or will  fulfill and  perform,  all its  material  obligations  with
respect to such permits  which are due to have been  fulfilled  and performed by
such date and no event has occurred  which  allows,  or after notice or lapse of
time would allow, revocation or termination thereof or results in any impairment
of the rights of the  holder of any such  permit,  except for such  revocations,
terminations and impairments  that would not,  individually or in the aggregate,
have a Material Adverse Effect subject in each case to such qualification as may
be set forth in the Prospectus; and, except as described in the Prospectus, none
of such permits  contains or will  contain any  restriction  that is  materially
burdensome to the  Partnership,  the Operating  Partnership and  Skelly-Belvieu,

reasonable   detail,   accurately  and  fairly  reflect  the   transactions  and
dispositions  of  assets  and (ii)  maintains  systems  of  internal  accounting
controls  sufficient to provide reasonable  assurances that (A) transactions are

differences.

     (gg)  Disclosure  Controls.  The  Partnership has established and maintains
disclosure controls and procedures (as such term is defined in Rule 13a-14 under

relating to the Partnership,  including its consolidated  subsidiaries,  is made
known to Valero GP's  principal  executive  officer and its principal  financial
officer by others  within  those  entities,  particularly  during the periods in
which the periodic  reports  required under the Exchange Act are being prepared;
(ii) have been evaluated for  effectiveness as of a date within 90 days prior to
the filing of the  Partnership's  most recent  annual or quarterly  report filed
with the Commission; and (iii) are effective in all material respects to perform
the functions for which they were established.

     (hh) No Identified  Problems Resulting from Disclosure  Controls.  Based on
the evaluation of its disclosure controls and procedures, the Partnership is not
aware of (i) any  significant  deficiency in the design or operation of internal
controls  which  could  adversely  affect the  Partnership's  ability to record,
process,  summarize  and report  financial  data or any material  weaknesses  in
internal  controls;  or (ii) any fraud,  whether or not material,  that involves
management or other employees who have a significant  role in the  Partnership's
internal controls.

                                       10


     (ii) No  Significant  Changes in Internal  Controls.  Since the date of the

significantly  affect internal  controls,  including any corrective actions with
regard to significant deficiencies and material weaknesses.

all taxes shown to be due pursuant to such returns,  other than those (i) which,
if not paid, would not have a Material  Adverse Effect,  or (ii) which are being
contested in good faith and for which adequate reserves have been established in
accordance with generally accepted accounting principles.

     (kk)  Related  Party  Transactions.  No  relationship,  direct or indirect,

such noncompliance with Environmental Laws, failure to receive required permits,
or  failure  to  comply  with  the  terms  and  conditions  of such  permits  or
liabilities in connection  with such release would not,  individually  or in the
aggregate,  have a Material Adverse Effect. The term "Hazardous  Material" means

waste" as defined in the Resource Conservation and Recovery Act, as amended, (C)

situated.  None of the Partnership Entities has received notice from any insurer
or  agent  of such  insurer  that  substantial  capital  improvements  or  other
expenditures  will have to be made in order to continue such insurance,  and all
such insurance is  outstanding  and duly in force on the date hereof and will be
outstanding and duly in force on each Delivery Date.

affairs,   management,   consolidated  financial  position,  partners'  capital,
members'  equity,  or results of operations of any of the Partnership  Entities,
taken as a whole, otherwise than as set forth or contemplated in the Prospectus;
and,  since  the  respective  dates  as of  which  information  is  given in the

dated such Delivery Date, of the chief executive officer and the chief financial
officer of Valero GP stating that (A) such officers have carefully  examined the
Registration   Statement  and  the  Prospectus,   (B)  in  their  opinion,   the
Registration   Statement,   including  the  documents  incorporated  therein  by
reference,  as of the Effective Time, did not include any untrue  statement of a
material  fact and did not omit to state a material  fact  required to be stated
therein or necessary in order to make the statements therein not misleading, and
the  Prospectus,  including the  Incorporated  Documents,  as of the date of the
Prospectus and as of such Delivery Date, did not and does not include any untrue
statement  of a material  fact and did not and does not omit to state a material
fact  necessary  in order to make the  statements  therein,  in the light of the
circumstances  under which they were made,  not  misleading,  and (C) as of such

to be performed or satisfied  hereunder on or prior to such  Delivery  Date,  no
stop order suspending the  effectiveness of the Registration  Statement has been
issued and no proceedings  for that purpose have been instituted or, to the best
of such officer's knowledge, are contemplated by the Commission,  and subsequent
to the date of the most recent financial statements contained in the Prospectus,
there has been no material  adverse change in the financial  position or results
of operations of the Partnership  Entities,  taken as a whole, or any change, or
any development involving a prospective material adverse change, in or affecting
the condition (financial or otherwise), results of operations or business of the
Partnership Entities, taken as a whole, except as set forth in the Prospectus.

                                       18


     (j) If any event shall have occurred on or prior to such Delivery Date that
requires  the  Partnership  under  Section  5(d)  to  prepare  an  amendment  or
supplement  to the  Prospectus,  such  amendment or  supplement  shall have been
prepared,  the  Underwriter  shall have been given a reasonable  opportunity  to
comment  thereon as provided in Section 5(d) hereof,  and copies  thereof  shall
have been  delivered to the  Underwriter  reasonably in advance of such Delivery
Date.

     (k) None of the Partnership Entities shall have sustained since the date of
the latest audited financial statements included or incorporated by reference in
the  Prospectus  any loss or  interference  with its business from fire,  flood,
explosion or other  calamity,  whether or not covered by insurance,  or from any
labor dispute or court or governmental action,  investigation,  order or decree,
otherwise than as set forth or contemplated  in the Prospectus;  nor shall there
have been a change in the  partners'  capital,  members'  interests or long-term
debt  of any of the  Partnership  Entities  or any  change,  or any  development
involving a prospective change, in or affecting the general affairs, management,
financial  position,  net worth or  results  of  operations  of the  Partnership
Entities,  otherwise than as set forth or contemplated  in the  Prospectus,  the
effect of which, in any case under this Section 7(k), is, in the judgment of the
Underwriter,  so material and adverse as to make it impracticable or inadvisable
to proceed with the public offering or the delivery of the Units being delivered
on such  Delivery  Date  on the  terms  and in the  manner  contemplated  in the
Prospectus.

     (l) No action  shall have been taken and no statute,  rule,  regulation  or
order shall have been enacted,  adopted or issued by any governmental  agency or
body which would, as of such Delivery Date,  prevent the issuance or sale of the
Units; and no injunction,  restraining order or order of any other nature by any
federal or state court of  competent  jurisdiction  shall have been issued as of
such Delivery Date which would prevent the issuance or sale of the Units.

     (m) Subsequent to the execution and delivery of this Agreement  there shall
not have occurred any of the following:  (i) trading in securities  generally on
the  New  York  Stock  Exchange  or  the  American  Stock  Exchange  or  in  the
over-the-counter  market or trading in any securities of the  Partnership on any
exchange  or in the  over-the-counter  market  shall  have been  suspended,  the
settlement of such trading  generally  shall have been  materially  disrupted or
minimum  prices shall have been  established on any such exchange or such market
by  the  Commission,  by  such  exchange  or by any  other  regulatory  body  or
governmental authority having jurisdiction, (ii) a banking moratorium shall have
been  declared by federal or state  authorities,  (iii) the United  States shall
have  become  engaged in  hostilities,  there shall have been an  escalation  in
hostilities  involving  the United States or there shall have been a declaration
of a national  emergency  or war by the United  States or (iv) there  shall have
occurred  such a material  adverse  change in  general  economic,  political  or
financial  conditions  including,  without limitation,  as a result of terrorist
activities after the date hereof (or the effect of  international  conditions on
the financial markets in the United States shall be such), as to make it, in the
judgment of the  Underwriter,  impracticable  or inadvisable to proceed with the
public  offering or sale of the Units being  delivered on such  Delivery Date on
the terms and in the manner contemplated by the Prospectus.

     (n) The New York Stock  Exchange shall have approved the Units for listing,
subject only to official notice of issuance.

     All such opinions,  certificates,  letters and documents mentioned above or
elsewhere  in this  Agreement  shall  be  deemed  to be in  compliance  with the
provisions hereof only if they are in form and substance reasonably satisfactory
to the Underwriter and to counsel for the Underwriter.

                                       19


     8. Indemnification and Contribution.

     (a) Each of the Partnership Parties, jointly and severally, shall indemnify
and hold harmless the  Underwriter,  its  directors,  officers and employees and
each person,  if any, who  controls  the  Underwriter  within the meaning of the
Securities Act, from and against any loss, claim, damage or liability,  joint or
several,  or any action in respect thereof  (including,  but not limited to, any
loss,  claim,  damage,  liability or action  relating to purchases  and sales of
Units),  to which the Underwriter,  director,  officer,  employee or controlling
person may become  subject,  under the Securities  Act or otherwise,  insofar as
such loss, claim,  damage,  liability or action arises out of, or is based upon,
(i) any  untrue  statement  or  alleged  untrue  statement  of a  material  fact
contained in (A) any Preliminary  Prospectus,  the Registration Statement or the
Prospectus  or in any  amendment  or  supplement  thereto or (B) any  written or
electronically  produced  materials or  information  electronically  provided to
investors by, or with the approval of, the  Partnership  in connection  with the
marketing of the offering of the Common Units ("Marketing  Materials") including
any road show or investor  presentations  made to investors  by the  Partnership
(whether in person or electronically),  (ii) the omission or alleged omission to
state in the Registration  Statement, or in any amendment or supplement thereto,
any  material  fact  required  to be stated  therein  or  necessary  to make the
statements  therein not  misleading,  (iii) the omission or alleged  omission to
state in any  Preliminary  Prospectus,  the  Prospectus  or in any  amendment or
supplement  thereto any material fact necessary to make the statements  therein,
in light of the  circumstances  under which they were made, not  misleading,  or
(iv) any act or  failure  to act or any  alleged  act or  failure  to act by the
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,  damage,  liability  or action  arising  out of or based  upon
matters covered by clause (i), (ii) or (iii) above (provided that no Partnership
Party shall be liable under this clause (iv) to the extent that it is determined
in a final judgment by a court of competent  jurisdiction that such loss, claim,
damage,  liability or action resulted directly from any such acts or failures to
act  undertaken  or omitted  to be taken by the  Underwriter  through  its gross
negligence or willful misconduct),  and shall reimburse the Underwriter and each
such director,  officer, employee or controlling person promptly upon demand for
any legal or other expenses  reasonably  incurred by the Underwriter,  director,
officer,  employee or controlling  person in connection  with  investigating  or
defending or preparing to defend  against or appearing as a third-party  witness
in connection  with any such loss,  claim,  damage,  liability or action as such
expenses are incurred;  provided,  however,  that no Partnership  Party shall be
liable  in any  such  case to the  extent  that any such  loss,  claim,  damage,
liability  or action  arises out of, or is based upon,  any untrue  statement or
alleged  untrue  statement  in or  omission  or alleged  omission  from any such
documents in reliance upon and in conformity with written information concerning
the Underwriter  furnished to the  Partnership  through the Underwriter by or on
behalf of the Underwriter  specifically for inclusion  therein which information
consists solely of the information specified in Section 8(e); provided, however,
that the Partnership  Parties shall not be liable to the  Underwriter  under the
indemnity  agreement in this Section 8(a) to the extent, but only to the extent,
that (x) such loss, claim,  damage, or liability of the Underwriter results from
an untrue  statement  of a  material  fact or an  omission  of a  material  fact
contained in the Preliminary Prospectus,  which untrue statement or omission was
completely  corrected in the Prospectus and (y) the  Partnership  had previously
furnished  sufficient  quantities  (as  requested  by  the  Underwriter)  of the
Prospectus to the Underwriter  within a reasonable  amount of time prior to such
sale or  such  confirmation  and  (z) the  Underwriter  failed  to  deliver  the
Prospectus,  if required by law to have so delivered it, and such delivery would
have cured the defect  giving rise to such loss,  claim,  liability,  expense or
damage.

                                       20


     (b) The  Underwriter  shall  indemnify and hold  harmless each  Partnership
Party, their officers and employees,  each of their directors,  and each person,
if  any,  who  controls  the  Partnership  Parties  within  the  meaning  of the
Securities  Act or the  Exchange Act  (collectively  referred to for purposes of
this  Section 8(b) and Section  8(d) as the  Partnership),  from and against any
loss,  claim,  damage or liability,  joint or several,  or any action in respect
thereof,  to  which  such  person  may  become  subject,  whether  commenced  or
threatened,  under the  Securities  Act, the Exchange  Act, any other federal or
state statutory law or regulation,  at common law or otherwise,  insofar as such
loss,  claim,  damage,  liability or action arises out of, or is based upon, (i)
any untrue statement or alleged untrue statement of a material fact contained in
any Preliminary  Prospectus,  the Registration Statement or the Prospectus or in
any amendment or supplement  thereto,  (ii) the omission or alleged  omission to
state in the Registration Statement, or any amendment or supplement thereto, any
material  fact  required to be stated  therein or necessary in order to make the
statements therein not misleading,  or (iii) the omission or alleged omission to
state in any  Preliminary  Prospectus,  the  Prospectus  or in any  amendment or
supplement  thereto any material fact necessary to make the statements  therein,
in the light of the  circumstances  under which they were made, not  misleading,
but in each case only to the extent that the untrue  statement or alleged untrue
statement  or omission  or alleged  omission  was made in  reliance  upon and in
conformity with written information  concerning the Underwriter furnished to the
Partnership  through  the  Underwriter  by  or  on  behalf  of  the  Underwriter
specifically  for inclusion  therein which  information  consists  solely of the
information  specified in Section 8(e), and shall  reimburse the Partnership for
any legal or other expenses reasonably incurred by the Partnership in connection
with investigating or defending or preparing to defend against or appearing as a
third party witness in connection with any such loss, claim,  damage,  liability
or action as such expenses are incurred.

     (c) Promptly after receipt by an indemnified  party under this Section 8 of
notice of any claim or the  commencement of any action,  the  indemnified  party
shall,  if a claim in respect  thereof is to be made  against  the  indemnifying
party  under this  Section 8,  notify the  indemnifying  party in writing of the
claim or the commencement of that action; provided, however, that the failure to
notify the  indemnifying  party shall not relieve it from any liability which it
may have  under  this  Section  8 except to the  extent  it has been  materially
prejudiced  (through the forfeiture of  substantive  rights or defenses) by such
failure and, provided further, that the failure to notify the indemnifying party
shall not  relieve  it from any  liability  which it may have to an  indemnified
party  otherwise than under this Section 8. If any such claim or action shall be
brought against an indemnified party, and it shall notify the indemnifying party
thereof, the indemnifying party shall be entitled to participate therein and, to
the  extent  that  it  wishes,   jointly  with  any  other  similarly   notified
indemnifying  party,  to assume the  defense  thereof  with  counsel  reasonably
satisfactory to the indemnified  party. After notice from the indemnifying party
to the indemnified  party of its election to assume the defense of such claim or
action,  the  indemnifying  party shall not be liable to the  indemnified  party
under this Section 8 for any legal or other  expenses  subsequently  incurred by
the  indemnified  party  in  connection  with the  defense  thereof  other  than
reasonable costs of investigation;  provided, however, that an indemnified party
shall have the right to employ its own counsel in any such action, but the fees,
expenses and other charges of such counsel for the indemnified  party 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 upon advice of counsel
to the  indemnified  party) 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 upon 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 reasonably
satisfactory  to the  indemnified  party 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 of attorneys  (in addition to any local  counsel) at any one time
for all  such  indemnified  party  or  parties.  Each  indemnified  party,  as a
condition of the indemnity agreements contained in Sections 8(a) and 8(b), shall
use all  reasonable  efforts to  cooperate  with the  indemnifying  party in the
defense of any such action or claim. No  indemnifying  party shall be liable for
any settlement of any such action  effected  without its written  consent (which
consent  shall not be  unreasonably  withheld),  but if settled with its written
consent or if there be a final  judgment  for the  plaintiff in any such action,
the  indemnifying  party agrees to indemnify and hold  harmless any  indemnified
party from and against any loss or  liability  by reason of such  settlement  or
judgment.  No indemnifying party shall, without the prior written consent of the
indemnified party (which consent shall not be unreasonably withheld), effect any
settlement,  compromise  or consent to the entry of any judgment with respect to
any pending or threatened  proceeding in respect of which any indemnified  party
is or could have been a party and indemnity could have been sought  hereunder by
such indemnified party unless such settlement, compromise or consent includes an
unconditional  release of such  indemnified  party from all  liability on claims
that are the subject matter of such proceeding.

                                       21


     The  obligations  of the  Partnership  Parties and the  Underwriter in this
Section 8 are in addition to any other liability that the Partnership Parties or
the Underwriter, as the case may be, may otherwise have, including in respect of
any breaches of  representations,  warranties and agreements  made herein by any
such party.

     (d) If the  indemnification  provided  for in this  Section 8 shall for any
reason be unavailable to or insufficient  to hold harmless an indemnified  party
under Section 8(a) or 8(b) in respect of any loss,  claim,  damage or liability,
or any action in respect thereof,  referred to therein,  then each  indemnifying
party shall, in lieu of indemnifying such indemnified  party,  contribute to the
amount  paid or  payable  by such  indemnified  party as a result of such  loss,
claim, damage or liability, or action in respect thereof, (i) in such proportion
as shall be  appropriate  to  reflect  the  relative  benefits  received  by the
Partnership,  on the one hand, and the Underwriter,  on the other hand, from the
offering of the Units or (ii) if the allocation  provided by clause (i) above is
not permitted by applicable law, in such proportion as is appropriate to reflect
not only the  relative  benefits  referred  to in clause  (i) above but also the
relative  fault of the  Partnership  on the one hand and the  Underwriter on the
other with respect to the  statements  or omissions  that resulted in such loss,
claim,  damage or liability,  or action in respect thereof, as well as any other
relevant  equitable  considerations.  The  relative  benefits  received  by  the
Partnership  on the one hand and the  Underwriter  on the other with  respect to
such  offering  shall be  deemed to be in the same  proportion  as the total net
proceeds from the offering of the Units purchased  under this Agreement  (before
deducting expenses) received by the Partnership,  on the one hand, and the total
underwriting  discounts and commissions received by the Underwriter with respect
to the Units  purchased  under this  Agreement,  on the other hand,  bear to the
total gross  proceeds  from the offering of the Units under this  Agreement,  in
each case as set forth in the table on the  cover  page of the  Prospectus.  The
relative 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  Partnership  or the
Underwriter,  the intent of the parties and their relative knowledge,  access to
information  and  opportunity  to correct or prevent such statement or omission.
The  Partnership  and the  Underwriter  agree  that  it  would  not be just  and
equitable if  contributions  pursuant to this Section 8 were to be determined by
pro rata  allocation  or by any other method of  allocation  which 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,  damage,
liability,  or action in respect  thereof,  referred to above in this  Section 8
shall be deemed to include,  for  purposes of this  Section  8(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 8(d), no Underwriter  shall be required to contribute
any amount in excess of the  amount by which the total  price at which the Units
underwritten  by it and  distributed  to the  public  was  offered to the public
exceeds the amount of any damages which the  Underwriter  has otherwise  paid or
become  liable to pay by reason of any untrue or  alleged  untrue  statement  or
omission or alleged omission.  No person guilty of fraudulent  misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution   from  any  person   who  was  not   guilty  of  such   fraudulent
misrepresentation.  The  Underwriter's  obligations to contribute as provided in
this Section 8(d) are several in  proportion  to their  respective  underwriting
obligations and not joint.

                                       22


     (e) The Underwriter  confirms and the Partnership  Parties acknowledge that
the  statements  with  respect  to  the  public  offering  of the  Units  by the
Underwriter  set forth on the cover page of the  Prospectus  Supplement  and the
concession and reallowance figures in the fourth paragraph and the statements in
the seventh, eighth, ninth, tenth, eleventh, fourteenth,  fifteenth,  sixteenth,
seventeenth,  eighteenth  and  nineteenth  paragraphs  under the  "Underwriting"
section  of the  Prospectus  Supplement  are  correct  and  constitute  the only
information  concerning the Underwriter  furnished in writing to the Partnership
by  or  on  behalf  of  the  Underwriter   specifically  for  inclusion  in  the
Registration Statement and the Prospectus.

     9.  Termination.  The  obligations  of  the  Underwriter  hereunder  may be
terminated by the Underwriter by notice given to and received by the Partnership
prior to delivery of and payment for the Firm Units if, prior to that time,  any
of the events  described  in  Section  7(k) or (m) shall  have  occurred  and be
continuing  or if the  Underwriter  shall  decline to purchase the Units for any
reason permitted under this Agreement.

     10. Reimbursement of Underwriter's  Expenses. If the Partnership shall fail
to tender the Units for  delivery to the  Underwriter  by reason of any failure,
refusal  or  inability  on the  part of any  Partnership  Party to  perform  any
agreement  on its part to be  performed,  or because any other  condition of the
Underwriter's  obligations hereunder required to be fulfilled by the Partnership
Parties is not fulfilled, the Partnership will reimburse the Underwriter for all
reasonable  out-of-pocket expenses (including fees and disbursements of counsel)
incurred by the  Underwriter in connection  with this Agreement and the proposed
purchase of the Units, and upon demand the Partnership shall pay the full amount
thereof to the Underwriter.

     11. Notices.  All statements,  requests,  notices and agreements  hereunder
shall be in writing, and:

Partnership of the issuance and sale of the Units contemplated thereby.

     19.  The   statements   in  the   Prospectus   under  the   captions   "Tax
Considerations," "Description of Common Units," and "Cash Distributions" insofar
as they  constitute  descriptions of agreements or refer to statements of law or
legal  conclusions,  fairly  summarize  the  matters  referred to therein in all
material respects, subject to the qualifications and assumptions stated therein.

     20. The Units conform in all material respects to the descriptions  thereof

                                       A-3

Prospectus,  as of its  date,  and the  Prospectus  Supplement  as of its  date,
appeared on its face to be appropriately  responsive in all material respects to
the  requirements of the Securities Act and the Rules and  Regulations,  except,
that in each  case,  we  express  no  opinion  as to the  financial  statements,
schedules and other financial or statistical  data included  therein or excluded
therefrom,  or  the  exhibits  to  the  Registration  Statement.   Each  of  the
Incorporated Documents filed prior to the date hereof appeared on its face to be
appropriately  responsive in all material  respects to the  requirements  of the
Exchange  Act of 1934,  as  amended  (the  "Exchange  Act"),  or the  rules  and
regulations  promulgated  under the Exchange Act, except,  that in each case, we
express no opinion as to the financial statements, schedules and other financial
or statistical data included therein or excluded  therefrom,  or the exhibits to
any of the Incorporated Documents.

as amended.

domain in the State of Texas to secure  rights-of-way  necessary  to operate and
maintain each of its common carrier pipelines situated in such State.

     In  addition,  such  counsel  shall  state that they have  participated  in
conferences with officers and other  representatives of the Partnership Entities
and the  independent  public  accountants  for the Partnership and the Operating
Partnership,  your representatives and your counsel at which the contents of the
Registration  Statement and the  Prospectus  and related  matters were discussed
and, although such counsel have not  independently  verified and are not passing
upon, and do not assume any  responsibility  for the accuracy,  completeness  or
fairness of the  statements  contained  in the  Registration  Statement  and the
Prospectus  (except and to the extent set forth in paragraph  19 above),  on the
basis of the foregoing, no facts have come to such counsel's attention that have
led them to believe that the Registration Statement,  including the Incorporated
Documents, as of its effective date, 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 statements therein not misleading, or that the Prospectus,
including the  Incorporated  Documents,  as of its issue date and as of the date
hereof,  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 statements
therein,  in  light  of the  circumstances  under  which  they  were  made,  not
misleading,  it being  understood  that such  counsel  expresses no statement or
belief  with  respect to (a) the  financial  statements  and  related  schedules
included therein,  including the notes and the auditor's report thereon, (b) the
other  information  of  a  financial  or  statistical  nature  included  in  the
Registration   Statement  or  the   Prospectus  and  (c)  the  exhibits  to  the
Registration Statement.

     In addition,  such counsel shall state that based solely on its review of a
copy  of the  Effectiveness  Order,  the  Registration  Statement  was  declared
effective under the Securities Act at 11:00 a.m.  (Washington D.C. time) on June
17, 2002.  Such  counsel  have also been orally  advised by the SEC that no stop
order  suspending  the  effectiveness  of the  Registration  Statement  has been
issued, and based solely on such counsel's  communications with the SEC, to such
counsel's  knowledge no proceedings for that purpose have been instituted or are
pending or threatened by the SEC. The Prospectus has been filed pursuant to Rule
424(b) in the manner and within the time period required by such Rule.

                                       A-4


     In rendering  such opinion,  such counsel may (A) rely in respect of maters
of fact upon certificates of officers and employees of the Partnership  Entities
and upon  information  obtained  from  public  officials,  (B) base its  opinion
regarding  the  enforceability  of the  Partnership  Agreement and the Operating
Partnership  Agreement  rendered in  paragraphs 14 and 15,  respectively,  on an
opinion of Delaware local counsel  reasonably  satisfactory to the  Underwriter,
(C)  assume  the legal  capacity  of all  natural  persons,  that all  documents
submitted to them as originals are authentic,  that all copies submitted to them
conform to the  authentic  originals  thereof,  and that the  signatures  on all
documents examined by them are genuine,  (D) state that their opinion is limited
to applicable  federal laws, the Delaware LP Act, the Delaware LLC Act, the DGCL
and the applicable  laws of the State of Texas,  and (E) state that they express
no opinion  with respect to state or local taxes or tax statutes to which any of
the limited partners of the Partnership Entities may be subject.

material respects as currently conducted or as contemplated by the Prospectus to
be conducted;  and, to the knowledge of such counsel after due inquiry,  none of
the Partnership  Entities has received any notice of proceedings relating to the

     16.  There  are no legal or  governmental  proceedings  pending  or, to the

representatives  and your  counsel,  at which the  contents of the  Registration

such  counsel  has not  independently  verified,  is not  passing on, and is not
assuming any  responsibility  for the accuracy,  completeness or fairness of the
statements contained in, the Registration  Statement and the Prospectus,  on the
basis of the foregoing, no facts have come to such counsel's attention that lead

schedules  included  therein,  including the notes thereto and auditor's  report
thereon,  (ii) the  other  information  of a  financial  or  statistical  nature
included in the Registration  Statement,  and (iii) the exhibits thereto,  as to
which such counsel need not  comment),  as of its effective  date,  contained an
untrue statement of a material fact or omitted to state a material fact required

or that the Prospectus, including the Incorporated Documents (other than (i) the
financial statements and related schedules included therein, including the notes
thereto and auditor's report thereon,  (ii) the other information of a financial
or  statistical  nature  included  in the  Prospectus,  and (iii)  the  exhibits

of each  Delivery  Date  contained  an untrue  statement  of a material  fact or
omitted to state a material fact  necessary to make the statements  therein,  in
the light of the circumstances under which they were made, not misleading.

                                       B-3

thereof,  and that the signatures on all documents  examined by him are genuine,
(C) state that his opinion is limited to federal laws,  the Delaware LP Act, the
Delaware LLC Act, the DGCL and the laws of the State of Texas and (D) state that
he  expresses no opinion with respect to state or local taxes or tax statutes to

                        FORM OF LOCK-UP LETTER AGREEMENT

Lehman Brothers Inc.                                              August 5, 2003
745 7th Avenue
New York, New York  10019

Dear Sirs:

The undersigned  understands that you, as underwriter,  propose to enter into an
Underwriting  Agreement  (the  "Underwriting  Agreement")  with the  Partnership
Parties  providing for the purchase by you of common units,  each representing a
limited partner interest (the "Common Units") in the  Partnership,  and that you
propose to reoffer the Common Units to the public (the "Offering").  Capitalized
terms  used  but not  defined  herein  have  the  meanings  given to them in the
Underwriting Agreement.

In consideration of the execution of the Underwriting  Agreement by you, and for
other good and valuable consideration, the undersigned hereby irrevocably agrees
that, without your prior written consent,  the undersigned will not, directly or
indirectly,  (1) offer for sale, sell,  pledge or otherwise dispose of (or enter
into any  transaction  or device that is designed  to, or could be expected  to,
result in the disposition by any person at any time in the future of) any Common
Units  (including,  without  limitation,  Common  Units that may be deemed to be
beneficially  owned  by  the  undersigned  in  accordance  with  the  rules  and
regulations  of the Commission and Common Units that may be issued upon exercise
of any option or warrant) or securities  convertible  into or  exchangeable  for
Common Units owned by the  undersigned  on the date of execution of this Lock-up
Letter Agreement or on the date of the completion of the Offering,  or (2) enter
into any swap or other  derivatives  transaction  that transfers to another,  in
whole or in part,  any of the  economic  benefits or risks of  ownership of such
Common Units, whether any such transaction  described in clause (1) or (2) above
is to be settled by delivery  of Common  Units or other  securities,  in cash or
otherwise, for a period of 90 days from the date of the Prospectus.

In  furtherance  of the foregoing,  the  Partnership  and its Transfer Agent are
hereby authorized to decline to make any transfer of securities if such transfer
would constitute a violation or breach of this Lock-Up Letter Agreement.

It is understood  that, if the Partnership  notifies you that it does not intend
to proceed with the  Offering,  if the  Underwriting  Agreement  does not become
effective,  or if the Underwriting  Agreement (other than the provisions thereof
that survive  termination) shall terminate or be terminated prior to payment for
and  delivery  of the  Common  Units,  the  undersigned  will be  released  from
[his/her] obligations under this Lock-Up Letter Agreement.

The undersigned  understands  that the Partnership and you will proceed with the
Offering in reliance on this Lock-Up Letter Agreement.

                                       C-1


Whether or not the  Offering  actually  occurs  depends on a number of  factors,
including  market  conditions.  Any  Offering  will only be made  pursuant to an
Underwriting  Agreement,  the terms of which are subject to negotiation  between
the Partnership and you.

The  undersigned  hereby  represents and warrants that the  undersigned has full
power and authority to enter into this Lock-Up Letter  Agreement and that,  upon
request,  the  undersigned  will execute any additional  documents  necessary in
connection with the enforcement hereof. Any obligations of the undersigned shall
be binding  upon the  [heirs and  personal  representatives]  (for  individuals)
[successors and assigns] (for nonnatural persons) of the undersigned.

Yours very truly,






                                      C-2
