                             Underwriting Agreement

                                                               December 10, 2002


To the Representatives named in
         Schedule I hereto of the
         Underwriters named in
         Schedule II hereto

Ladies and Gentlemen:

         Valero Energy Corporation, a Delaware corporation (the "COMPANY"),
proposes to issue and sell to the underwriters named in Schedule II hereto (the
"UNDERWRITERS"), for whom you are acting as representatives (the
"REPRESENTATIVES"), the principal amount of its debt securities identified in
Schedule I hereto (the "Securities"), to be issued under the indenture specified
in Schedule I hereto (the "INDENTURE") between the Company and the Trustee
identified in such Schedules (the "TRUSTEE"). If the firm or firms listed in
Schedule II hereto include only the firm or firms listed in Schedule I hereto,
then the terms "Underwriters" and "Representatives," as used herein, shall each
be deemed to refer to such firm or firms.


         The Company has prepared and filed with the Securities and Exchange
Commission (the "COMMISSION") in accordance with the provisions of the
Securities Act of 1933, as amended, and the rules and regulations of the
Commission thereunder (collectively, the "SECURITIES ACT"), a registration
statement (the file number of which is set forth in Schedule I hereto) on Form
S-3, relating to certain debt securities (the "SHELF SECURITIES") to be issued
from time to time by the Company. The Company also has filed with, or proposes
to file with, the Commission pursuant to Rule 424 under the Securities Act a
prospectus supplement specifically relating to the Securities. The registration
statement as amended to the date of this Agreement is hereinafter referred to as
the "REGISTRATION STATEMENT" and the related prospectus covering the Shelf
Securities in the form first used to confirm sales of the Securities is
hereinafter referred to as the "BASIC PROSPECTUS". The Basic Prospectus as
supplemented by the pro-



spectus supplement specifically relating to the Securities in the form first
used to confirm sales of the Securities is hereinafter referred to as the
"PROSPECTUS". If the Company has filed an abbreviated registration statement
pursuant to Rule 462(b) under the Securities Act (the "RULE 462 REGISTRATION
STATEMENT"), then any reference herein to the term "Registration Statement"
shall be deemed to include such Rule 462 Registration Statement. Any reference
in this Agreement to the Registration Statement, the Basic Prospectus, any
preliminary form of prospectus (a "PRELIMINARY PROSPECTUS") previously filed
with the Commission pursuant to Rule 424 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 which were filed under the
Securities Exchange Act of 1934, as amended, and the rules and regulations of
the Commission thereunder (collectively, the "EXCHANGE ACT") on or before the
date of this Agreement or the date of the Basic Prospectus, any preliminary
prospectus or the Prospectus, as the case may be; and any reference to "amend",
"amendment" or "supplement" with respect to the Registration Statement, the
Basic Prospectus, any preliminary prospectus or the Prospectus shall be deemed
to refer to and include any documents filed under the Exchange Act after the
date of this Agreement, or the date of the Basic Prospectus, any preliminary
prospectus or the Prospectus, as the case may be, which are deemed to be
incorporated by reference therein.

         The Company hereby agrees with the Underwriters as follows:

           1. The Company agrees to issue and sell the Securities to the several
Underwriters as hereinafter provided, and each Underwriter, on the basis of the
representations and warranties herein contained, but subject to the conditions
hereinafter stated, agrees to purchase, severally and not jointly, from the
Company the respective principal amount of Securities set forth opposite such
Underwriter's name in Schedule II hereto at the purchase price set forth in
Schedule I hereto plus accrued interest, if any, from the date specified in
Schedule I hereto to the date of payment and delivery.

           2. The Company understands that the several Underwriters intend (i)
to make a public offering of their respective portions of the Securities and
(ii) initially to offer the Securities upon the terms set forth in the
Prospectus.

           3. Payment for the Securities shall be made by wire transfer in
immediately available funds to the account specified by the Company to the
Representatives, no later than noon the Business Day (as defined below) prior to

                                       2


Business Day (as defined below) thereafter, as you and the Company may agree in
writing). As used herein, the term "BUSINESS DAY" means any day other than a day
on which banks are permitted or required to be closed in New York City. The time
and date of such payment and delivery with respect to the Securities are
referred to herein as the "CLOSING DATE".

         Payment for the Securities shall be made against delivery to the

connection with the transfer to the Underwriters of the Securities duly paid by
the Company. The Global Note will be made available for inspection by the
Representatives at such place as the Representatives and the Company shall agree
not later than 1:00 P.M., New York City time, on the Business Day prior to the
Closing Date.

         delivered by the Company.

                  (f) The authorized capital stock of the Company conforms as to

         Prospectus.

                  (h) The execution and delivery by the Company of, and the
         performance by the Company of its obligations under, this Agreement,
         the Indenture and the Securities will not contravene any provision of
         applicable law or the certificate of incorporation or by-laws of the
         Company or any agreement, indenture or instrument binding upon the
         Company or any of its subsidiaries that is material to the Company and

         effect on the business, properties, financial condition or results of
         operations of the Company and its subsidiaries, taken as a whole, and
         no event or condition has occurred or exists which, with the giving of
         notice or the lapse of time or both, would result in any such violation
         or default which would have such an effect. Neither the Company nor any
         of its subsidiaries is in violation of any law, ordinance, governmental
         rule or regulation or court decree to which it may be subject, which
         violation could reasonably be expected to have a material adverse
         effect on the business, properties, financial condition or results of
         operations of the Company and its subsidiaries, taken as a whole.

                  (j) There has not occurred any material adverse change, or any

         supplements thereto subsequent to the date of this Agreement).

         Company or any of its subsidiaries is subject, that are required to be
         described in the Registration Statement or the Prospectus and are not

         that are required to be described in the Registration Statement or the
         Prospectus or to be filed as exhibits to the Registration Statement
         that are not described or filed as required.

                  (l) Each preliminary prospectus filed as part of the
         registration statement as originally filed or as part of any amendment
         thereto, or filed pursuant to Rule 424 under the Securities Act,

         authorizations, certifications, accreditations, franchises, approvals,
         grants of rights by, or filings or registrations with, any federal,
         state, local or foreign court or governmental or public body,
         authority, or other instrumentality or third person (including without
         limitation the Federal Energy Regulatory Commission ("FERC")) (any of
         the foregoing a "LICENSE") necessary for the Company and its
         subsidiaries to own, build, maintain or operate their respective
         businesses or properties have been duly authorized and obtained, and
         are in full force and effect, except where the failure to so be
         obtained or in effect would not, individually or in the aggregate, have
         a material adverse effect on the Company and its subsidiaries, taken as
         a whole; and the Company and its subsidiaries are in compliance in all
         material respects with all provisions thereof; no event has occurred

         which would reasonably be expected to have a material adverse effect on
         the Company and its subsidiaries, taken as a whole; no material License
         is the subject of any pending or, to the best of the Company's
         knowledge, threatened challenge or revocation which, if such License

         effect on the Company and its subsidiaries, taken as a whole; the

         License that has not already been obtained from, or effect any material
         filing or registration that has not already been effected with, the
         FERC or any other federal, state or local regulatory authority in
         connection with the execution and delivery of this Agreement, the
         Indenture or the Securities; and except, in each case, as described in
         the Prospectus (exclusive of any amendments or supplements thereto
         subsequent to the date of this Agreement).

                  (o) The Company and its subsidiaries (i) are in compliance
         with any and all applicable foreign, federal, state and local laws and
         regulations relating to the protection of human health and safety, the
         environment or hazardous or toxic substances or wastes, pollutants or

         or approval, except where such noncompliance with Environmental Laws,
         failure to receive required permits, licenses or other approvals or
         failure to comply with the terms and conditions of such permits,
         licenses or approvals would not, singly or in the aggregate, have a
         material adverse effect on the Company and its subsidiaries, taken as a
         whole; and except, in each case, as described in the Prospectus
         (exclusive of any amendments or supplements thereto subsequent to the
         date of this Agreement).

                  (p) Except as described in the Prospectus (exclusive of any
         amendments or supplements thereto subsequent to the date of this
         Agreement), there are no costs or liabilities associated with
         Environmental Laws (including, without limitation, any capital or
         operating expenditures required for clean-up, closure of properties or
         compliance with Environmental Laws or any permit, license or approval,
         any related constraints on operating activities and any potential
         liabilities to third parties) which would, singly or in the aggregate,
         have a material adverse effect on the Company and its subsidiaries,
         taken as a whole.

                  (q) The Company has prepared its financial statements on a
         consistent basis in accordance with generally accepted accounting
         principles. The pro forma financial statements of the Company, if any,
         and the related notes thereto, included in the Prospectus present
         fairly in all material respects the pro forma financial position of the
         Company, as of the dates indicated and the results of its operations
         for the periods specified; any such pro forma financial information,
         and the related notes thereto, included in the Prospectus have been
         prepared in accordance with the applicable requirements of the

                                       7


         Exchange Act and are based upon good faith estimates and assumptions
         believed by the Company to be reasonable.

                  (r) Neither the Company nor any of its subsidiaries is a
         "holding company", a "subsidiary company" of a "holding company", an
         "affiliate" of a "holding company" or of a "subsidiary company" of a
         "holding company", or a "public utility", as each of such terms is
         defined in the Public Utility Holding Company Act of 1935, as amended,
         and the rules and regulations thereunder.

                  (s) The Company and its subsidiaries have good and
         indefeasible title to all items of real property and good and
         defensible title to all personal property owned by them and the right
         to use all other property used or proposed to be used by them in the
         ordinary course of business, in each case free and clear of all liens,
         encumbrances and defects except such as are described or referred to in
         the Prospectus or such as do not materially adversely affect the value
         of such property and do not unreasonably interfere with the use made or
         proposed to be made of such property by the Company and its
         subsidiaries; and any real property and buildings held under lease by
         the Company and its subsidiaries are held by them under valid, existing
         and enforceable leases with such exceptions as are not material and do
         not unreasonably interfere with the use made or proposed to be made of
         such property and buildings by the Company or its subsidiaries.

                  (t) Immediately after any sale of Securities by the Company
         hereunder, the aggregate initial offering price of Securities which
         have been issued and sold by the Company hereunder and of any
         securities of the Company (other than the Securities) that shall have
         been issued and sold pursuant to the Registration Statement will not
         exceed the aggregate initial offering price of securities registered
         under the Registration Statement.

         5. The Company covenants and agrees with each of the several
Underwriters as follows:

                  (a) to file the Prospectus in a form approved by you pursuant
         to Rule 424 under the Securities Act not later than the Commission's
         close of business on the second Business Day following the date of
         determination of the offering price of the Securities or, if
         applicable, such earlier time as may be required by Rule 424(b);

                  (b) to furnish to you, without charge, five conformed copies
         of the Registration Statement (including exhibits thereto) and for

         exhibits thereto) and to furnish to you in New York City, without
         charge, prior to 10:00 a.m. New York City time on the business day next
         succeeding the date of this Agreement and during the period mentioned
         in Section 5(e) below, as many copies of the Prospectus and any
         supplements and amendments thereto or to the Registration Statement as
         you may reasonably request;

                  (c) from the date hereof and prior to the Closing Date, to
         furnish to you a copy of any proposed amendment or supplement to the
         Registration Statement or the Prospectus, for your review, and not to
         file any such proposed amendment or supplement to which you reasonably
         object;

                  (d) to file promptly all reports and any definitive proxy or
         information statements required to be filed by the Company with the
         Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the
         Exchange Act for so long as the delivery of a prospectus is required in
         connection with the offering or sale of the Securities, and during such
         same period, to advise you promptly, and to confirm such advice in
         writing, (i) when any amendment to the Registration Statement shall
         have become effective, (ii) of any request by the Commission for any
         amendment to the Registration Statement or any amendment or supplement
         to the Prospectus or for any additional information, (iii) of the
         issuance by the Commission of any stop order suspending the
         effectiveness of the Registration Statement or the initiation or
         threatening of any proceeding for that purpose, and (iv) of the receipt
         by the Company of any notification with respect to any suspension of
         the qualification of the Securities for offer and sale in any
         jurisdiction or the initiation or threatening of any proceeding for
         such purpose; and to use its best efforts to prevent the issuance of
         any such stop order or notification and, if issued, to obtain as soon
         as possible the withdrawal thereof;

                  (e) if, during such period after the first date of the public
         offering of the Securities as in the opinion of counsel for the
         Underwriters a prospectus relating to the Securities is required by law
         to be delivered in connection with sales by an Underwriter or dealer,
         any event shall occur as a result of which it is necessary to amend or
         supplement the Prospectus in order to make the statements therein, in
         the light of the circumstances when the Prospectus is delivered to a
         purchaser, not misleading, or if it is necessary to amend or supplement

                  respect to such legal matters, documents and proceedings and
                  accurately summarize the matters referred to therein; and

                        (viii) the Company is not, and after giving effect to

         to state a material fact required to be stated therein or necessary to
         make the statements therein not misleading or (ii) (except for
         financial statements and schedules and other financial and statistical
         data and the Forms T-1 as to which such counsel need not express any

         or omits 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.

         Registration Statement and the Prospectus; and

                  (i) you shall have received on and as of the Closing Date an
         opinion of Davis Polk & Wardwell, counsel to the Underwriters, in form
         and substance satisfactory to you.

           7. The Company agrees to indemnify and hold harmless each
Underwriter, each affiliate of any Underwriter which assists such Underwriter in
the distribution of the Securities and each person, if any, who controls any
Underwriter within the meaning of either Section 15 of the Securities Act or
Section 20 of the Exchange Act, from and against any and all losses, claims,
damages and liabilities (including without limitation the legal fees and other
expenses reasonably incurred in connection with any suit, action or proceeding
or any claim asserted) caused by any untrue statement or alleged untrue
statement of a material fact contained in the Registration Statement or the
Prospectus (as amended or supplemented if the Company shall have furnished any
amendments or supplements thereto) or any preliminary prospectus, or caused by
any omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading,
except insofar as such losses, claims, damages or liabilities are caused by any
untrue statement or omission or alleged untrue statement or omission made in
reliance upon and in conformity with information relating to any Underwriter
furnished to the Company in writing by such Underwriter through the
Representatives expressly for use therein; provided, however, that the foregoing
indemnity agreement with respect to any preliminary prospectus shall not inure
to the benefit of any Underwriter from whom the person asserting any such
losses, claims, damages or liabilities purchased Securities, or any person
controlling such Underwriter, if a copy of the Prospectus (as then amended or
supplemented if the Company shall have furnished any amendments or supplements
thereto) was not sent or given by or on behalf of such Underwriter to such
person, if required by law so to have been delivered, at or prior to the written
confirmation of the sale of the Securities to such person, and if the Prospectus
(as so amended or supplemented) would have cured the defect giving rise to such
losses, claims, damages or liabilities, unless such failure is the result of
noncompliance by the Company with Section 5(b) hereof.

         Each Underwriter agrees, severally and not jointly, to indemnify and
hold harmless the Company, its directors, its officers who sign the Registration
Statement and each person who controls the Company within the meaning of Section
15 of the Securities Act and Section 20 of the Exchange Act, to the same extent
as the foregoing indemnity from the Company to each Underwriter, but only with
reference to information relating to such Underwriter furnished to the Company
in writing by such Underwriter through the Representatives expressly for use in
the Registration

                                       17


Statement, the Prospectus, any amendment or supplement thereto, or any
preliminary prospectus.



         If any suit, action, proceeding (including any governmental or
regulatory investigation), claim or demand shall be brought or asserted against
any person in respect of which indemnity may be sought pursuant to either of the
two preceding paragraphs, such person (the "INDEMNIFIED PERSON") shall promptly
notify the person against whom such indemnity may be sought (the "INDEMNIFYING
PERSON") in writing, and the Indemnifying Person, upon request of the
Indemnified Person, shall retain counsel reasonably satisfactory to the
Indemnified Person to represent the Indemnified Person and any others the
Indemnifying Person may designate in such proceeding and shall pay the fees and
expenses of such counsel related to such proceeding. In any such proceeding, any
Indemnified Person shall have the right to retain its own counsel, but the fees
and expenses of such counsel shall be at the expense of such Indemnified Person
unless (i) the Indemnifying Person and the Indemnified Person shall have
mutually agreed to the contrary, (ii) the Indemnifying Person has failed within
a reasonable time to retain counsel reasonably satisfactory to the Indemnified
Person or (iii) the named parties in any such proceeding (including any
impleaded parties) include both the Indemnifying Person and the Indemnified
Person and representation of both parties by the same counsel would be
inappropriate due to actual or potential differing interests between them. It is
understood that the Indemnifying Person shall not, in connection with any
proceeding or related proceeding in the same jurisdiction, be liable for the
fees and expenses of more than one separate firm (in addition to any local
counsel) for all Indemnified Persons, and that all such fees and expenses shall
be reimbursed as they are incurred. Any such separate firm for the Underwriters,
each affiliate of any Underwriter which assists such Underwriter in the
distribution of the Securities and such control persons of Underwriters shall be
designated in writing by the first of the named Representatives on Schedule I
hereto and any such separate firm for the Company, its directors, its officers
who sign the Registration Statement and such control persons of the Company or
authorized representatives shall be designated in writing by the Company. The
Indemnifying Person shall not be liable for any settlement of any proceeding
effected without its written consent, but if settled with such consent or if
there be a final judgment for the plaintiff, the Indemnifying Person agrees to
indemnify any Indemnified Person from and against any loss or liability by
reason of such settlement or judgment. Notwithstanding the foregoing sentence,
if at any time an Indemnified Person shall have requested an Indemnifying Person
to reimburse the Indemnified Person for fees and expenses of counsel as
contemplated by the third sentence of this paragraph, the Indemnifying Person
agrees that it shall be liable for any settlement of any proceeding effected
without its written consent if (i) such settlement is entered into more than 30
days after receipt by such Indemnifying Person of the aforesaid request and (ii)
such Indemnifying Person shall not have reimbursed the

                                       18


Indemnified Person in accordance with such request prior to the date of such
settlement. No Indemnifying Person shall, without the prior written consent of
the Indemnified Person, effect any settlement of any pending or threatened
proceeding in respect of which any Indemnified Person is or could have been a
party and indemnity could have been sought hereunder by such Indemnified Person,
unless such settlement includes an unconditional release of such Indemnified
Person from all liability on claims that are the subject matter of such
proceeding.

         If the indemnification provided for in the first and second paragraphs
of this Section 7 is unavailable to an Indemnified Person or insufficient in
respect of any losses, claims, damages or liabilities referred to therein, then
each Indemnifying Person under such paragraph, in lieu of indemnifying such
Indemnified Person thereunder, shall contribute to the amount paid or payable by
such Indemnified Person as a result of such losses, claims, damages or
liabilities (i) in such proportion as is appropriate to reflect the relative
benefits received by the Company on the one hand and the Underwriters on the
other hand from the offering of the Securities 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 Company on the one
hand and the Underwriters on the other in connection with the statements or
omissions that resulted in such losses, claims, damages or liabilities, as well
as any other relevant equitable considerations. The relative benefits received
by the Company on the one hand and the Underwriters on the other shall be deemed
to be in the same respective proportions as the net proceeds from the offering
of such Securities (before deducting expenses) received by the Company and the
total underwriting discounts and the commissions received by the Underwriters
bear to the aggregate public offering price of the Securities. The relative
fault of the Company on the one hand and the Underwriters on the other shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Company or by the
Underwriters and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission.

         The Company and the Underwriters agree that it would not be just and
equitable if contribution pursuant to this Section 7 were determined by pro rata
allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation that does not take account of the
equitable considerations referred to in the immediately preceding paragraph. The
amount paid or payable by an Indemnified Person as a result of the losses,
claims, damages and liabilities referred to in the immediately preceding
paragraph shall be deemed to include, subject to the limitations set forth
above, any legal or other expenses reasonably incurred by such Indemnified
Person in connection with investigating or defending any such action

                                       19


or claim. Notwithstanding the provisions of this Section 7, in no event shall an
Underwriter be required to contribute any amount in excess of the amount by
which the total price at which the Securities underwritten by it and distributed
to the public were offered to the public exceeds the amount of any damages that
such Underwriter has otherwise been required to pay by reason of such 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 Underwriters' obligations to
contribute pursuant to this Section 7 are several in proportion to the
respective principal amount of the Securities set forth opposite their names in
Schedule I hereto, and not joint.

         The remedies provided for in this Section 7 are not exclusive and shall
not limit any rights or remedies which may otherwise be available to any
indemnified party at law or in equity.

         The indemnity and contribution agreements contained in this Section 7
and the representations and warranties of the Company set forth in this
Agreement shall remain operative and in full force and effect regardless of (i)
any termination of this Agreement, (ii) any investigation made by or on behalf
of any Underwriter or any person controlling any Underwriter or by or on behalf
of the Company, its officers or directors or any other person controlling the
Company and (iii) acceptance of and payment for any of the Securities.

           8. Notwithstanding anything herein contained, this Agreement may be
terminated in the absolute discretion of the Representatives, by notice given to
the Company, if after the execution and delivery of this Agreement and prior to
the Closing Date (i) trading generally shall have been suspended or materially
limited on or by, as the case may be, any of the New York Stock Exchange, the
American Stock Exchange or the National Association of Securities Dealers, Inc.,
(ii) trading of any securities of or guaranteed by the Company shall have been
suspended on any exchange or in any over-the-counter market, (iii) a general
moratorium on commercial banking activities in New York shall have been declared
by either Federal or New York State authorities, or (iv) there shall have
occurred any outbreak or escalation of hostilities or any change in financial
markets or any calamity or crisis that, in the judgment of the Representatives,
is material and adverse and which, in the judgment of the Representatives, makes
it impracticable to market the Securities on the terms and in the manner
contemplated in the Prospectus.

           9. If, on the Closing Date, any one or more of the Underwriters shall
fail or refuse to purchase Securities which it or they have agreed to purchase
under this

                                       20


Agreement, and the aggregate principal amount of Securities which such
defaulting Underwriter or Underwriters agreed but failed or refused to purchase
is not more than one-tenth of the aggregate principal amount of the Securities,
the other Underwriters shall be obligated severally in the proportions that the
principal amount of Securities set forth opposite their respective names in
Schedule II hereto bears to the aggregate principal amount of Securities set
forth opposite the names of all such non-defaulting Underwriters, or in such
other proportions as the Representatives may specify, to purchase the Securities
which such defaulting Underwriter or Underwriters agreed but failed or refused
to purchase on such date; provided that in no event shall the principal amount
of Securities that any Underwriter has agreed to purchase pursuant to Section 1
be increased pursuant to this Section 9 by an amount in excess of one-tenth of
such principal amount of Securities without the written consent of such
Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail
or refuse to purchase Securities and the aggregate principal amount of
Securities with respect to which such default occurs is more than one-tenth of
the aggregate principal amount of Securities to be purchased, and arrangements
satisfactory to you and the Company for the purchase of such Securities are not
made within 36 hours after such default, this Agreement shall terminate without
liability on the part of any non-defaulting Underwriter or the Company. In any
such case either you or the Company 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 under this
paragraph shall not relieve any defaulting Underwriter from liability in respect
of any default of such Underwriter under this Agreement.

          10. (a) If this Agreement shall be terminated by the Underwriters, or
any of them, because of any failure or refusal on the part of the Company to
comply with the terms or to fulfill any of the conditions of this Agreement, or
if for any reason the Company shall be unable to perform its obligations under
this Agreement or any condition of the Underwriters' obligations cannot be
fulfilled, the Company agrees to reimburse the Underwriters or such Underwriters
as have so terminated this Agreement with respect to themselves, severally, for
all out-of-pocket expenses (including the fees and expenses of their counsel)
reasonably incurred by such Underwriters in connection with this Agreement or
the offering of Securities.

                  (b) If this Agreement shall be terminated by the Underwriters
         pursuant to Section 8 or because of any failure or refusal on the part
         of the Company to comply with the terms or to fulfill any of the
         conditions of this Agreement, or if for any reason the Company shall be
         unable to perform its obligations under this Agreement or any condition
         of the Underwriters' obligations cannot be fulfilled, the Company
         agrees that it will purchase from

                                       21


         UBS Warburg LLC (or such affiliate as UBS Warburg LLC may designate)
         $150 million aggregate principal amount of the Company's 6.75% Notes
         due December 15, 2032 (the "Old Securities") for $178,200,529 and will
         pay such amount immediately by wire transfer of immediately available
         funds to an account designated by UBS Warburg LLC, and UBS Warburg
         agrees to sell (or cause its affiliate) to sell such Old Securities to
         the Company; provided that if UBS AG has not yet purchased the Old
         Securities at the time the Agreement is terminated, UBS Warburg LLC may
         elect instead to cause UBS AG to assign all of its rights and
         obligations to purchase the Old Securities to the Company, and the
         Company agrees that upon such an assignment it will assume all of the
         rights and obligations of UBS AG to purchase the Old Securities and
         will immediately pay to UBS Warburg LLC $28,200,529 by wire transfer of
         immediately available funds to an account designated by UBS Warburg
         LLC. Upon any such termination and satisfaction of the Company's
         obligations under this Section 10(b), all agreements entered into in
         connection with the Old Securities shall terminate.

          11. This Agreement shall inure to the benefit of and be binding upon
the Company, each affiliate of any Underwriter which assists such Underwriter in
the distribution of the Securities, the Underwriters, any controlling persons
referred to herein and their respective successors and assigns. Nothing
expressed or mentioned in this Agreement is intended or shall be construed to
give any other person, firm or corporation any legal or equitable right, remedy
or claim under or in respect of this Agreement or any provision herein
contained. No purchaser of Securities from any Underwriter shall be deemed to be
a successor by reason merely of such purchase.

          12. Any action by the Underwriters hereunder may be taken by you
jointly or by the first of the named Representatives set forth in Schedule I
hereto alone on behalf of the Underwriters, and any such action taken by you
jointly or by the first of the named Representatives set forth in Schedule I
hereto alone shall be binding upon the Underwriters. All notices and other
communications hereunder shall be in writing and shall be deemed to have been
duly given if mailed or transmitted by any standard form of telecommunication.
Notices to the Underwriters shall be given at the address set forth in Schedule
I hereto. Notices to the Company shall be given to it at Valero Energy
Corporation, One Valero Place, San Antonio, Texas 78212 (facsimile: (210)
370-2490); Attention: Corporate Secretary.

          13. This Agreement may be signed in counterparts, each of which shall
be an original and all of which together shall constitute one and the same
instrument.

                                       22


          14. This Agreement shall be governed by and construed in accordance
with the laws of the State of New York, without giving effect to the conflicts
of laws provisions thereof.
