Dear Sirs and Mesdames:

         Valero Energy Corporation, a Delaware corporation (the "COMPANY"),
proposes to issue and sell to the several Underwriters named in Schedule I
hereto (the "UNDERWRITERS"), an aggregate of 6,300,000 shares of its Common
Stock, par value $.01 per share (the "SHARES").

         The shares of common stock, par value $.01 per share, of the Company to
be outstanding after giving effect to the sales contemplated hereby are
hereinafter referred to as the "COMMON STOCK." The Shares will have attached
thereto preferred share purchase rights (the "RIGHTS") issued pursuant to the
Rights Agreement (the "RIGHTS AGREEMENT") dated as of July 17, 1997 between the
Company and Computershare Investors Services L.L.C., as Rights Agent.

         The Company has 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 (the
"SECURITIES ACT"), a registration statement on Form S-3 (registration no. 333-
84820), including a related prospectus, relating to the registration of certain
shares of Common Stock including the Shares and the related Rights and certain
debt and other securities (the "SHELF SECURITIES"), to be sold from time to time
by the Company. The registration statement as amended at the date of this
Agreement, including information, if any, deemed to be part of the registration
statement at the time of effectiveness pursuant to Rule 430A under the
Securities Act is hereinafter referred to as the "REGISTRATION STATEMENT," and
the prospectus included therein relating to the Shelf Securities, in the form
first used to confirm sales of the Shares, is hereinafter referred to as the
"BASIC PROSPECTUS." The Basic Prospectus, as supplemented by the prospectus
supplement dated March 25, 2003 (the "PROSPECTUS SUPPLEMENT"), relating to the
Shares, in the form first used to confirm sales of the Shares is hereinafter
referred to as the "PROSPECTUS". If the Company has filed an abbreviated
registration statement pursuant to Rule 462(b)


                                       1

reference herein to the term "Registration Statement" shall be deemed to include
such Rule 462 Registration Statement. Any reference to the term Registration
Statement, the Basic Prospectus or the Prospectus shall include the documents
incorporated therein by reference. The terms "SUPPLEMENT" and "AMENDMENT" or
"AMEND" as used in this Agreement shall include all documents subsequently filed
by the Company with the Commission pursuant to the Securities Exchange Act of
1934, as amended (the "EXCHANGE ACT"), that are deemed to be incorporated by
reference in the Prospectus.

          (j) The execution and delivery by the Company of, and the performance
         by the Company of its obligations under, this Agreement and the Rights
         Agreement will not contravene any provision of applicable law or the
         certificate of incorporation or by-laws of the Company or any agreement
         or other instrument binding upon the Company or any of its subsidiaries
         that is material to the Company and its subsidiaries, taken as a whole,
         or any judgment, order or decree of any governmental body, agency or
         court having jurisdiction over the Company or any subsidiary, and no
         consent, approval, authorization or order of, or qualification with,

         its corporate charter or by-laws or other constitutive document or in

         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

         operations of the Company and its subsidiaries, taken as a whole.

          (l) There has not occurred any material adverse change, or any
         development involving a prospective material adverse change in the
         condition, financial or otherwise, or in the earnings, business or
         operations of the Company and its subsidiaries, taken as a whole, from
         that set forth in the Prospectus (exclusive of any amendments or
         supplements thereto subsequent to the date of this Agreement).

          (m) There are no legal or governmental investigations or proceedings
         pending or threatened to which the Company or any of its subsidiaries
         is a party or to which any of the properties of the Company or any of
         its subsidiaries is subject, that are required to be described in the
         Registration Statement or the Prospectus and are not so described or
         any statutes, regulations, contracts or other documents that are
         required to be


                                       4



         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.

           (n) The Company is not, and after giving effect to the offering and
         sale of the Shares and the application of the proceeds thereof as
         described in the Prospectus will not be, required to register as an
         "investment company" as such term is defined in the Investment Company

         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 permits (or with the passage of time would permit) the revocation
         or termination of any License, or which could result in the imposition
         of any restriction thereon, which is of such a nature or the effect of
         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
         were revoked, would reasonably be expected to have a material adverse
         effect on the Company and its subsidiaries, taken as a whole; the
         Company and its subsidiaries are not required to obtain any material
         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 or the
         Rights Agreement; 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) 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
         contaminants


                                       5



         ("ENVIRONMENTAL LAWS"), (ii) have received all permits, licenses or
         other approvals required of them under applicable Environmental Laws to
         conduct their respective businesses and (iii) are in compliance with
         all terms and conditions of any such permit, license 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).

          (q) 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.

          (r) There are no contracts, agreements or understandings between the
         Company and any person granting such person the right to require the
         Company to file a registration statement under the Securities Act with
         respect to any securities of the Company or to require the Company to
         include such securities with the Shares registered pursuant to the
         Registration Statement.

          (s) The Company has prepared its financial statements on a consistent
         basis in accordance with generally accepted accounting principles.

          (t) Neither the Company nor any of its subsidiaries is a "holding
         company", a "subsidiary company" or 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.

          (u) 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


                                       6



         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.

                  (x) Immediately after any sale of Shares by the Company
         hereunder, the aggregate initial offering price of Shares which have
         been issued and sold by the Company hereunder and of any securities of
         the Company (other than the Shares) 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.

     2. Agreements to Sell and Purchase. The Company hereby agrees to sell to
the several Underwriters, and each Underwriter, upon the basis of the
representations and warranties herein contained, but subject to the conditions

The Company hereby agrees that, without the prior written consent of Morgan
Stanley & Co. Incorporated and J.P. Morgan Securities, Inc., it will not, during

Prospectus, or (E) the issuance by the Company of unregistered securities in
connection with acquisitions, which securities will not be registered for resale
before the end of the 90-day period.

     3. Terms of Public Offering. The Company is advised by you that the
Underwriters propose to make a public offering of their respective portions of
the Shares as soon after the Registration Statement and this Agreement have
become effective as in your judgment is advisable. The Company is further
advised by you that the Shares are to be offered to the public initially at
$40.25 a share (the "PUBLIC OFFERING PRICE") and to certain dealers selected by
you at a price that represents a concession not in excess of $0.35 a share under
the Public Offering Price.

     4. Payment and Delivery. Payment for the Shares to be sold by the Company
shall be made to the Company in Federal or other funds immediately available in
New York City against delivery of such Shares for the respective accounts of the
several Underwriters at 10:00 a.m., New York City time, on March 28, 2003, or at
such other time on the same or such other date, not later than April 4, 2003, as
shall be designated in writing by you. The time and date of such payment are
hereinafter referred to as the "CLOSING DATE."

     The Shares shall be delivered in electronic form through the facilities of
the Depository Trust Company ("DTC") and registered in such names and in such
denominations as you shall request in writing not later than one full business
day prior to the Closing Date. The Shares shall be delivered to DTC on the
Closing Date, for the respective accounts of the several Underwriters, with any
transfer taxes payable in connection with the transfer of the Shares to the

the Underwriters to purchase and pay for the Shares on the Closing Date are
subject to the following further conditions:

                  (a) no stop order suspending the effectiveness of the
         Registration Statement shall have been issued under the Securities Act
         and no proceedings for that purpose shall have been instituted or shall
         be pending or, to your knowledge or the knowledge of the Company, shall
         be contemplated by the Commission, and any request on the part of the
         Commission for additional information shall have been complied with to
         the reasonable satisfaction of counsel for the Underwriters.


                                       8



                  (b) Subsequent to the execution and delivery of this Agreement
         and prior to the Closing Date:

                       (i) there shall not have occurred any downgrading, nor
                  shall any notice have been given of any intended or potential
                  downgrading or of any review for a possible change that does
                  not indicate an improvement, in the rating accorded any of the
                  Company's securities by any "nationally recognized statistical
                  rating organization," as such term is defined for purposes of
                  Rule 436(g)(2) under the Securities Act; and

                      (ii) there shall not have occurred any change, or any
                  development involving a prospective change, in the condition,
                  financial or otherwise, or in the earnings, business or
                  operations of the Company and its subsidiaries, taken as a
                  whole, from that set forth in the Prospectus (exclusive of any
                  amendments or supplements thereto subsequent to the date of
                  this Agreement) that, in your judgment, is material and
                  adverse and that makes it, in your judgment, impracticable to
                  market the Shares on the terms and in the manner contemplated
                  in the Prospectus.

                  (c) The Underwriters shall have received on the Closing Date a
         certificate, dated the Closing Date and signed by an executive officer
         of the Company, to the effect set forth in Section 5(b)(i) above and to
         the effect that the representations and warranties of the Company
         contained in this Agreement are true and correct as of the Closing Date
         and that the Company has complied with all of the agreements and
         satisfied all of the conditions on its part to be performed or
         satisfied hereunder on or before the Closing Date.

                  The officer signing and delivering such certificate may rely
         upon the best of his or her knowledge as to proceedings threatened.

          (d)   The Underwriters shall have received on the Closing Date an
         opinion of Baker Botts L.L.P., outside counsel for the Company, to the
         effect that:

                           (vii) after due inquiry, such counsel does not know
                  of any legal or governmental investigations or proceedings
                  pending or threatened to which the Company or any of its
                  subsidiaries is a party or to which any of the properties of

                  required to be described in the Registration Statement or the
                  Prospectus and are not so described or of any statutes,
                  regulations, contracts or other documents that are required to

                  applicable Environmental Laws, (B) have not received all

                  conditions of any such permit, license 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

                           (ix) the documents incorporated by reference in the

                  and other financial or statistical data included therein or
                  omitted therefrom, as to which such counsel need express no
                  opinion), as of the dates they were filed with the Commission

                  to form in all material respects with the requirements of the
                  Exchange Act and the regulations thereunder.

         In addition, such counsel shall state that nothing has come to such
         counsel's attention to cause such counsel to believe that (A) the
         Registration Statement and Prospectus (except for financial statements
         and schedules and other financial and statistical data included therein
         as to which such counsel need not comment) do not comply as to form in
         all material respects with the Securities Act and the applicable rules
         and regulations of the Commission thereunder or (B)(i) (except for
         financial statements and schedules and other financial and statistical

         necessary to make the statements therein not misleading or (ii) (except
         for financial statements and schedules and other financial and
         statistical data as to which such counsel need not express any belief)
         the Prospectus contains any untrue statement of a material fact or
         omits to state a material fact necessary in order to make the

          (b) During the period after the first date of the public offering of
         the Shares as in the opinion of counsel for the Underwriters the
         Prospectus is required by law to be delivered in connection with sales
         by an Underwriter or dealer, before amending or supplementing the
         Registration Statement or the Prospectus, (including by filing any
         document that would as a result thereof be incorporated by reference in
         the Prospectus) to furnish to you a copy of each such proposed
         amendment, supplement or other document and not to file any such
         proposed amendment, supplement or other document to which you
         reasonably object, and to file with the Commission within the
         applicable period specified in Rule 424(b) under the Securities Act any
         prospectus required to be filed pursuant to such Rule.

          (c) During the period after the first date of the public offering of

         be filed with the Commission pursuant to Section 13, 14 or 15(d) of the
         Exchange Act.

          (d) If, during such period after the first date of the public offering
         of the Shares as in the opinion of counsel for the Underwriters the
         Prospectus is required by law to be delivered in connection with sales
         by an Underwriter or dealer, any event shall occur or condition exist
         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 existing when the Prospectus is delivered to a purchaser,
         not misleading, or if, in the opinion of counsel for the Underwriters,
         it is necessary to amend or supplement the Prospectus to comply with
         applicable law, forthwith to prepare, file with the Commission and
         furnish, at its own expense, to the Underwriters and to the dealers

         Shares may have been sold by you on behalf of the Underwriters and to
         any other dealers upon request, either amendments or supplements to the
         Prospectus, so that the statements in the Prospectus as so amended or
         supplemented will not, in the light of the circumstances when the
         Prospectus is delivered to a purchaser, be misleading or so that the
         Prospectus, as amended or supplemented, will comply with law.

which provision is not otherwise made in this Section, provided that the
Underwriters agree to pay all of the costs and expenses relating to any "road
show" relating directly to the Underwriters, including the cost of chartering
any aircraft. It is understood that except as provided in this Section, Section
8 entitled "Indemnity and Contribution", and the last paragraph of Section 10
below, the Underwriters will pay all of their costs and expenses, including fees
and disbursements of their counsel, stock transfer taxes payable on resale of
any of the Shares by them and any advertising expenses connected with any offers
they may make.

               8. Indemnity and Contribution. (a) The Company agrees to
indemnify and hold harmless each Underwriter 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, any
legal or other expenses reasonably incurred in connection with defending or
investigating any such action or claim) caused by any untrue statement or
alleged untrue statement of a material fact contained in the Registration
Statement or any amendment thereof, any preliminary prospectus or the Prospectus
(as amended or supplemented if the Company shall have furnished any amendments
or supplements thereto), 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 such untrue statement or omission or
alleged untrue statement or omission based upon information relating to any
Underwriter furnished to the Company in writing by such Underwriter through you
or through your counsel 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 Shares, 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 Shares 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 6(a) hereof.


                                       17



              (b) Each Underwriter agrees, severally and not jointly, to
         indemnify and hold harmless the Company, the directors of the Company,
         the officers of the Company who sign the Registration Statement and
         each person, if any, who controls the Company 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, any legal or other expenses
         reasonably incurred in connection with defending or investigating any
         such action or claim) caused by any untrue statement or alleged untrue
         statement of a material fact contained in the Registration Statement or
         any amendment thereof, any preliminary prospectus or the Prospectus (as
         amended or supplemented if the Company shall have furnished any
         amendments or supplements thereto), 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, but
         only with reference to information relating to such Underwriter
         furnished to the Company in writing by such Underwriter through you or
         through your counsel expressly for use in the Registration Statement,
         any preliminary prospectus, the Prospectus or any amendments or
         supplements thereto.

              (c) In case any proceeding (including any governmental
         investigation) shall be instituted involving any person in respect of
         which indemnity may be sought pursuant to Section 8(a) or 8(b), such
         person (the "INDEMNIFIED PARTY") shall promptly notify the person
         against whom such indemnity may be sought (the "INDEMNIFYING PARTY") in
         writing and the indemnifying party, upon request of the indemnified
         party, shall retain counsel reasonably satisfactory to the indemnified
         party to represent the indemnified party and any others the
         indemnifying party may designate in such proceeding and shall pay the
         fees and disbursements of such counsel related to such proceeding. In
         any such proceeding, any indemnified party 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 party unless (i) the indemnifying
         party and the indemnified party shall have mutually agreed to the
         retention of such counsel or (ii) the named parties to any such
         proceeding (including any impleaded parties) include both the
         indemnifying party and the indemnified party 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 party shall not, in respect of the legal expenses of any
         indemnified party in connection with any proceeding or related
         proceedings in the same jurisdiction, be liable for (i) the fees and
         expenses of more than one separate firm (in addition to any local
         counsel) for all Underwriters and all persons, if any, who control any
         Underwriter within the meaning of either Section 15 of the Securities
         Act or Section 20 of the Exchange Act and (ii) the fees and expenses of
         more than one separate firm (in addition to any local counsel) for the
         Company, its directors, its officers who sign the


                                       18



         Registration Statement and each person, if any, who controls the
         Company within the meaning of either such Section, and that all such
         fees and expenses shall be reimbursed as they are incurred. In the case
         of any such separate firm for the Underwriters and such control persons
         of any Underwriters, such firm shall be designated in writing by Morgan
         Stanley & Co. Incorporated and J.P. Morgan Securities, Inc. In the case
         of any such separate firm for the Company, and such directors, officers
         and control persons of the Company, such firm shall be designated in
         writing by the Company. The indemnifying party 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 party agrees to indemnify the
         indemnified party from and against any loss or liability by reason of
         such settlement or judgment. Notwithstanding the foregoing sentence, if
         at any time an indemnified party shall have requested an indemnifying
         party to reimburse the indemnified party for fees and expenses of
         counsel as contemplated by the second and third sentences of this
         paragraph, the indemnifying party agrees that it shall be liable for
         any settlement of any proceeding effected without its written consent
         if (i) such settlement is entered into more than 30 days after receipt
         by such indemnifying party of the aforesaid request and (ii) such
         indemnifying party shall not have reimbursed the indemnified party in
         accordance with such request prior to the date of such settlement. No
         indemnifying party shall, without the prior written consent of the
         indemnified party, effect any settlement of any pending or threatened
         proceeding in respect of which any indemnified party is or could have
         been a party and indemnity could have been sought hereunder by such
         indemnified party, unless such settlement includes an unconditional
         release of such indemnified party from all liability on claims that are
         the subject matter of such proceeding.

              (d) To the extent the indemnification provided for in Section 8(a)
         or 8(b) is unavailable to an indemnified party or insufficient in
         respect of any losses, claims, damages or liabilities referred to
         therein, then each indemnifying party under such subsection, in lieu of
         indemnifying such indemnified party thereunder, shall contribute to the
         amount paid or payable by such indemnified party 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
         indemnifying party or parties on the one hand and the indemnified party
         or parties on the other hand from the offering of the Shares or (ii) if
         the allocation provided by clause 8(d)(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 8(d)(i) above but also
         the relative fault of the indemnifying party or parties on the one hand
         and of the indemnified party or parties on the other hand 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 hand in connection with the
         offering of the Shares shall be deemed to be in the same respective


                                       19




         proportions as the net proceeds from the offering of the Shares
         (before deducting expenses) received by the Company and the total
         underwriting discounts and commissions received by the Underwriters, in
         each case as set forth in the table on the cover of the Prospectus,
         bear to the aggregate Public Offering Price of the Shares. The relative
         fault of the Company on the one hand and the Underwriters on the other
         hand 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
         Underwriters' respective obligations to contribute pursuant to this
         Section 8 are several in proportion to the respective number of Shares
         they have purchased hereunder, and not joint.

              (e) The Company and the Underwriters agree that it would not be
         just or equitable if contribution pursuant to this Section 8 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 Section 8(d). The amount paid or payable by an
         indemnified party 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 party
         in connection with investigating or defending any such action or claim.
         Notwithstanding the provisions of this Section 8, no Underwriter shall
         be required to contribute any amount in excess of the amount by which
         the total price at which the Shares 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 remedies provided for in this Section
         8 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.

              (f) The indemnity and contribution provisions contained in this
         Section 8 and the representations, warranties and other statements of
         the Company contained in this Agreement shall remain operative and in
         full force and effect regardless of any termination of this Agreement,
         any investigation made by or on behalf of any Underwriter or any person
         controlling any Underwriter, or the Company, its officers or directors
         or any person controlling the Company and acceptance of and payment for
         any of the Shares.


                                       20



         9. Termination. This Agreement shall be subject to termination by
notice given by you to the Company, if (a) 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 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 your judgment, is material
and adverse and (b) in the case of any of the events specified in clauses
9(a)(i) through 9(a)(iv), such event, singly or together with any other such
event, makes it, in your judgment, impracticable to market the Shares on the
terms and in the manner contemplated in the Prospectus.

         10. Effectiveness; Defaulting Underwriters. This Agreement shall become
effective upon the execution and delivery hereof by the parties hereto.

         If, on the Closing Date, any Underwriter or Underwriters shall fail or
refuse to purchase Shares and the aggregate number of Shares with respect to
which such default occurs is more than one-tenth the aggregate number of Shares
to be purchased, and arrangements satisfactory to you and the Company for the
purchase of such Shares 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.

         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, the Company will 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 disbursements of their counsel)
reasonably incurred by such Underwriters in connection with this Agreement or
the offering contemplated hereunder.


                                       21



         11. Counterparts. This Agreement may be signed in two or more
counterparts, each of which shall be an original, with the same effect as if the
signatures thereto and hereto were upon the same instrument.

         12. Applicable Law. This Agreement shall be governed by and construed
in accordance with the internal laws of the State of New York.

         13. Headings. The headings of the sections of this Agreement have been
inserted for convenience of reference only and shall not be deemed a part of
this Agreement.

         14. Notices. 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 to Morgan Stanley & Co. Incorporated, 1585 Broadway, New York, New York

Morgan Stanley & Co. Incorporated
J.P. Morgan Securities Inc.
c/o  Morgan Stanley & Co. Incorporated
     1585 Broadway
     New York, New York 10036

Dear Sirs and Mesdames:

         The undersigned understands that Morgan Stanley & Co. Incorporated
("MORGAN STANLEY") and J.P. Morgan Securities, Inc. ("J.P. MORGAN") propose to
enter into an Underwriting Agreement (the "UNDERWRITING AGREEMENT") with
Valero Energy Corporation, a Delaware corporation (the "COMPANY"), providing
for the public offering (the "PUBLIC OFFERING") by the several underwriters
named therein, (the "UNDERWRITERS"), of shares (the "SHARES") of the common
stock, par value $.01 per share, of the Company (the "COMMON STOCK").

         To induce the Underwriters that may participate in the Public Offering
to continue their efforts in connection with the Public Offering, the
undersigned hereby agrees that, without the prior written consent of Morgan
Stanley and J.P. Morgan Securities, Inc., he will not, during the period
commencing on the date hereof and ending 90 days after the date of the final
prospectus supplement relating to the Public Offering (the "PROSPECTUS
SUPPLEMENT"), (1) offer, pledge, sell, contract to sell, sell any option or
contract to purchase, purchase any option or contract to sell, grant any option,
right or warrant to purchase, lend, or otherwise transfer or dispose of,
directly or indirectly, any shares of Common Stock or any securities convertible
into or exercisable or exchangeable for Common Stock, or (2) 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 Stock, whether any such
transaction described in clause (1) or (2) above is to be settled by delivery of
Common Stock or such other securities, in cash or otherwise. The foregoing
sentence shall not apply to the sale of any securities to the Underwriters
pursuant to the Underwriting Agreement or pursuant to any other underwriting
agreement entered into between the Company and Morgan Stanley and J.P. Morgan,
as lead underwriters. In addition, the undersigned agrees that, without the
prior written consent of Morgan Stanley and J.P. Morgan Securities, Inc., he
will not, during the period commencing on the




date hereof and ending 90 days after the date of the final Prospectus
Supplement, make any demand for or exercise any right with respect to, the
registration of any shares of Common Stock or any security convertible into or
exercisable or exchangeable for Common Stock. The undersigned also agrees and
consents to the entry of stop transfer instructions with the Company's transfer
agent and registrar against the transfer of the undersigned's shares of Common
Stock except in compliance with the foregoing restrictions.

         The undersigned understands that the Company and the Underwriters are
relying upon this Lock-Up Agreement in proceeding toward consummation of the
Public Offering. The undersigned further understands that this Lock-Up Agreement
is irrevocable and shall be binding upon the undersigned's heirs, legal
representatives, successors and assigns.

         Whether or not the Public Offering actually occurs depends on a number
of factors, including market conditions. Any Public Offering will only be made
pursuant to an Underwriting Agreement, the terms of which are subject to
negotiation between the Company and the Underwriters. Notwithstanding anything
herein to the contrary, this agreement will terminate if the Underwriting
Agreement is terminated prior to the delivery of the Shares thereunder.




                                            Very truly yours,



                                            -----------------------------------
