                   VALERO ENERGY CORPORATION AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1.   BASIS OF PRESENTATION AND PRINCIPLES OF CONSOLIDATION

As used in this report, the term Valero may refer to Valero Energy  Corporation,
one or more of its consolidated  subsidiaries,  or all of them taken as a whole.
The term UDS  Acquisition  refers to the  merger of  Ultramar  Diamond  Shamrock
Corporation (UDS) into Valero effective December 31, 2001.

Valero,  an  independent  refining and marketing  company,  owns and operates 12
refineries in the United States and Canada with a combined  throughput  capacity
of  approximately  1.9 million barrels per day. Valero markets refined  products
through  an  extensive  bulk  and  rack  marketing  network  and  a  network  of
approximately 4,100 retail outlets in the United States and eastern Canada under
various brand names including  Diamond  Shamrock(R),  Shamrock(R),  Ultramar(R),
Valero(R),  Beacon(R),  Total(R) and Exxon(R).  Valero's operations are affected
by:
     o    company-specific  factors,  primarily  refinery  utilization rates and
          refinery maintenance turnarounds;
     o    seasonal factors,  such as the demand for refined products,  primarily
          gasoline,  during the summer driving season and heating oil during the
          winter season; and
     o    industry factors, such as movements in and the absolute price of crude
          oil, the demand for and prices of refined  products,  industry  supply
          capacity, and competitor refinery maintenance turnarounds.

These unaudited consolidated financial statements include the accounts of Valero
and subsidiaries in which it has a controlling  interest.  Investments in 50% or
less owned entities are accounted for using the equity method of accounting (see
Note 3 for a  discussion  of the  reporting  change for Valero's  investment  in
Valero L.P.).  Intercompany  balances and  transactions  have been eliminated in
consolidation.

These  unaudited   consolidated  financial  statements  have  been  prepared  in
accordance  with United States  generally  accepted  accounting  principles  for
interim financial information and with the instructions to Form 10-Q and Article
10 of Regulation S-X of the Securities Exchange Act of 1934.  Accordingly,  they
do not  include  all of the  information  and notes  required  by United  States
generally  accepted  accounting  principles  (GAAP)  for  complete  consolidated
financial statements. In the opinion of management,  all adjustments (consisting
of normal recurring accruals)  considered necessary for a fair presentation have
been included.  Operating  results for the three months ended March 31, 2003 are
not  necessarily  indicative  of the results  that may be expected  for the year
ending December 31, 2003.

The balance  sheet as of December  31,  2002 has been  derived  from the audited
financial  statements  as of that date.  For further  information,  refer to the
consolidated  financial statements and notes thereto included in Valero's Annual
Report on Form 10-K for the year ended December 31, 2002.

Certain  previously  reported  amounts have been  reclassified to conform to the
2003 presentation.

2.   ACCOUNTING PRONOUNCEMENTS

FASB Statement No. 143

In June 2001, the Financial  Accounting  Standards Board (FASB) issued Statement
No.  143,   "Accounting  for  Asset  Retirement   Obligations."  This  statement
established financial accounting and reporting

                                       7


                   VALERO ENERGY CORPORATION AND SUBSIDIARIES

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)


standards for obligations  associated with the retirement of tangible long-lived
assets  and the  associated  asset  retirement  costs.  The  provisions  of this
statement  apply  to  legal  obligations   associated  with  the  retirement  of
long-lived  assets that result from the acquisition,  construction,  development
and/or  the  normal  operation  of  a  long-lived  asset,   except  for  certain
obligations of lessees.

Effective  January 1, 2003,  Valero adopted  Statement No. 143 and recognized an
asset  retirement  obligation  of  $30.0  million,  which is  included  in other
long-term liabilities,  and an increase to net property,  plant and equipment of
$25.8 million. The cumulative effect of implementing  Statement No. 143 resulted
in a pre-tax  loss of $4.2  million,  which was  included in other  income,  net
versus  presentation  as the  cumulative  effect of an accounting  change due to
immateriality.  This  asset  retirement  obligation  relates  to the  removal of
underground storage tanks from Valero's retail sites. Valero has also determined
that an asset  retirement  obligation  exists related to certain of its refinery
assets.  However, the fair value of the asset retirement  obligation  associated
with these refinery  assets cannot be reasonably  estimated since the settlement
dates  are  indeterminate;  therefore,  no  obligation  was  recorded  for these
refinery assets.

The following pro forma financial information summarizes the impact of Statement
No. 143 on 2002  financial  information  as if the  statement  had been  applied
retroactively to January 1, 2002:

                                             As Reported             Pro forma

  Loss per common share
    - assuming dilution................        $ (0.37)               $ (0.37)

FASB Interpretation No. 45
In November 2002, the FASB issued Interpretation No. 45, "Guarantor's Accounting
and Disclosure  Requirements for Guarantees,  Including  Indirect  Guarantees of
Indebtedness of Others" (FIN 45). FIN 45 addresses the disclosures to be made by
a guarantor in its interim and annual financial statements about its obligations
under  guarantees.  These disclosure  requirements  were effective for financial
statements of interim and annual  periods ending after December 15, 2002 and are
included  in Note 14. FIN 45 also  clarifies  that a  guarantor  is  required to
recognize,  at the  inception of a guarantee,  a liability for the fair value of
the  obligation  undertaken  in  issuing  the  guarantee.  The  recognition  and
measurement  provisions of this  interpretation  are applicable on a prospective
basis to guarantees issued or modified after December 31, 2002. Since Valero has
not entered  into or modified  any  guarantees  that are subject to FIN 45 since
December 31, 2002, there was no impact on Valero's financial position or results
of operations as a result of adopting FIN 45.

                   VALERO ENERGY CORPORATION AND SUBSIDIARIES

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)


FASB Interpretation No. 46
In January 2003, the FASB issued Interpretation No. 46 (FIN 46),  "Consolidation
of Variable  Interest  Entities,"  which requires an enterprise to consolidate a
variable  interest entity (VIE) if the enterprise is the primary  beneficiary of
the VIE. FIN 46 applies  immediately to VIEs created after January 31, 2003, and
to VIEs in which an enterprise  obtains an interest  after that date. It applies
in the first fiscal year or interim period beginning after June 15, 2003 to VIEs
in which an enterprise  holds a variable  interest  created  before  February 1,
2003. FIN 46 may be applied prospectively with a cumulative effect adjustment as
of the date on  which it is first  adopted  or by  restating  previously  issued
financial  statements for one or more years with a cumulative  effect adjustment
as of the  beginning of the first year  restated.  As of March 31, 2003,  Valero
held an interest in several  potential  VIEs and is  currently in the process of
determining the effect of adoption on July 1, 2003.

FASB Statement No. 149
In April 2003, the FASB issued Statement No. 149, "Amendment of Statement 133 on
Derivative  Instruments  and  Hedging  Activities."  This  statement  amends and
clarifies  financial  accounting  and  reporting  for  derivative   instruments,
including certain derivative  instruments  embedded in other contracts,  and for
hedging   activities  under  Statement  No.  133,   "Accounting  for  Derivative
Instruments and Hedging Activities." The provisions of Statement No. 149:
     o    clarify the  circumstances  under which a contract with an initial net
          investment meets the characteristic of a derivative,
     o    clarify when a derivative contains a financing component,
     o    amend the  definition  of an  underlying  (for  example,  a  specified
          interest rate, security price, commodity price, foreign exchange rate,
          etc.) to conform it to language used in FIN 45 and
     o    amend certain other existing pronouncements.

Statement No. 149 is effective for contracts entered into or modified after June
30,  2003.  Valero  will  adopt  this  statement  effective  July 1, 2003 and is
currently  evaluating the effect of the statement on its financial  position and
results of operations.

3. INVESTMENT IN AND TRANSACTIONS WITH VALERO L.P.

As of  December  31,  2002,  Valero  owned  73.6%  of  Valero  L.P.,  a  limited
partnership  that owns and  operates  crude oil and  refined  product  pipeline,
terminalling and storage tank assets.

Effective  March 18,  2003,  Valero L.P.  issued  5,750,000  common units to the
public  for  aggregate  proceeds  of  $211.3  million  and  completed  a private
placement of $250 million of debt. The net proceeds,  after issuance  costs,  of
$200.3 million and $247.8 million, respectively,  combined with borrowings under
Valero L.P.'s credit  facility and a  contribution  of $4.3 million by Valero to
maintain its 2% general  partner  interest in Valero  L.P.,  were used to fund a
redemption of common units from Valero and the  acquisition  of certain  storage
tanks and a pipeline system from Valero discussed further below.

Subsequent to Valero L.P.'s equity and debt offerings,  Valero L.P. redeemed 3.8
million of its common  units from  Valero  for $137.0  million,  including  $2.9
million  representing  the  redemption  of a  proportionate  amount of  Valero's
general  partner  interest.  The proceeds from the redemption are reflected as a
reduction to Valero's  investment in Valero L.P.  This redemption, combined with
the common unit


                                       9

                   VALERO ENERGY CORPORATION AND SUBSIDIARIES

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

issuance discussed above, reduced Valero's ownership of Valero L.P. to 49.5%. At
the same time,  Valero L.P.  amended  its  partnership  agreement  to reduce the
minimum  vote  required to remove the  general  partner  from  66-2/3% to 58% of
Valero L.P.'s  outstanding  common and  subordinated  units, and to exclude from
participation in such a vote the units held by affiliates of Valero. As a result
of the issuance and redemption of Valero L.P.  common units and the  partnership
agreement  changes,  effective March 18, 2003,  Valero ceased  consolidation  of
Valero L.P. and began using the equity  method to account for its  investment in
Valero L.P.

Subsequent to the equity and debt  offerings  and the common unit  redemption by
Valero L.P. discussed above,  Valero contributed to Valero L.P. 58 crude oil and
intermediate  feedstock storage tanks located at Valero's Corpus Christi,  Texas
City and Benicia Refineries for $200 million.  Valero also contributed to Valero
L.P. a refined products  pipeline system for $150 million.  This  three-pipeline
system connects  Valero's Corpus Christi and Three Rivers  Refineries to markets
in Houston, San Antonio and the Texas Rio Grande Valley. The contribution of the
storage  tank assets and the pipeline  system  resulted in proceeds in excess of
the carrying value of the  contributed  assets of $190.0 million for Valero.  Of
this excess, $94.1 million was recorded as a reduction to Valero's investment in
Valero L.P. because of Valero's continuing ownership interest in Valero L.P. The
remaining  $95.9 million of excess was deferred and recorded in other  long-term

facilities.  Under  various  agreements,  Valero has agreed to use Valero L.P.'s
pipelines to transport  crude oil shipped to and refined  products  shipped from
certain  of  Valero's  refineries  and  to use  Valero  L.P.'s  refined  product
terminals for certain terminalling services. In addition, Valero provides Valero
L.P. with the corporate functions of legal, accounting,  treasury,  engineering,
information  technology  and other  services  for an annual fee of $5.2  million
through  July 2008,  and Valero  provides  personnel  to Valero  L.P. to perform
operating  and  maintenance  services  with respect to certain  assets for which
Valero  receives  reimbursement  from  Valero  L.P.  Valero  has also  agreed to
indemnify Valero L.P. from certain  environmental  liabilities related to assets
sold by Valero to Valero  L.P.  that were known on the date the assets were sold
or are discovered  within a specified number of years after the assets were sold
as a result of events  occurring  or  conditions  existing  prior to the date of
sale.

Beginning March 19, 2003, Valero recognized in refining  operating expenses both
its  costs  related  to  the  throughput,  handling,  terminalling  and  service
agreements  with  Valero L.P.  and the  receipt  from Valero L.P. of payment for
operating,  maintenance and administrative services provided by Valero to Valero
L.P.

The increase in the gross cost for customer lists and Canadian retail operations
is due to the fluctuation in foreign  currency  exchange rates from December 31,
2002 to March 31, 2003.

All of  Valero's  intangible  assets are subject to  amortization.  Amortization
expense for  intangible  assets was $7.9  million and $5.0 million for the three
months  ended March 31, 2003 and 2002,  respectively.  The  estimated  aggregate
amortization  expense for the years  ending  December  31, 2003  through 2007 is
approximately $24 million per year.

The carrying value of goodwill  decreased  $128.5 million from December 31, 2002
to March  31,  2003  due to the  reclassification  of the  goodwill  related  to
Valero's  investment in Valero L.P. as a result of Valero ceasing  consolidation
of Valero L.P., as discussed in Note 3.

These  changes in current  assets and current  liabilities  differ from  changes
between amounts reflected in the applicable  consolidated balance sheets for the
respective  periods for the following  reasons.  The amounts shown above exclude
changes in cash and temporary cash  investments,  assets held for sale,  current
deferred income tax assets and liabilities, and short-term debt, current portion
of long-term debt and capital lease obligations. Also, certain noncash investing
activities  discussed  below are  excluded  from the table  above.  In addition,
certain differences between  consolidated balance sheet changes and consolidated
statement of cash flow changes  reflected above result from translating  foreign
currency denominated amounts at different exchange rates.

Noncash investing activities for the three months ended March 31, 2003 included:
     o    the  recognition  of a $30.0 million asset  retirement  obligation and
          associated  asset retirement cost in accordance with Statement No. 143
          and
     o    adjustments   to   property,   plant   and   equipment,    accumulated
          depreciation,   and  certain   current  and   noncurrent   assets  and
          liabilities  associated  with the  change  to cease  consolidation  of
          Valero  L.P.  and  use the  equity  method  to  account  for  Valero's
          investment in Valero L.P. effective March 18, 2003.

Noncash investing activities for the three months ended March 31, 2002 included:

10. PRICE RISK MANAGEMENT ACTIVITIES

Commodity Price Risk

Valero is exposed to market  risks  related to the  volatility  of crude oil and
refined product  prices,  as well as volatility in the price of natural gas used
in its  refining  operations.  To reduce the  impact of this  price  volatility,
Valero uses derivative  commodity  instruments  (swaps,  futures and options) to
manage its exposure to:
     o    changes in the fair value of a portion of its refinery  feedstock  and
          refined  product  inventories and a portion of its  unrecognized  firm
          commitments to purchase these inventories (fair value hedges);
     o    changes  in cash  flows of  certain  forecasted  transactions  such as
          forecasted  feedstock  purchases,  natural gas  purchases  and refined
          product sales (cash flow hedges); and
     o    price  volatility on a portion of its refined product  inventories and
          on certain forecasted feedstock and refined product purchases that are
          not  designated  as either  fair value or cash flow  hedges  (economic
          hedges).
In addition,  Valero uses derivative commodity  instruments for trading purposes
based on its fundamental and technical analysis of market conditions.

Interest Rate Risk
Valero is  exposed  to market  risk for  changes in  interest  rates  related to
certain of its long-term  debt  obligations.  Interest rate swap  agreements are
used to manage  Valero's fixed to floating  interest rate position by converting
certain fixed-rate debt to floating-rate debt.

Foreign Currency Risk
Valero is exposed to exchange rate  fluctuations on transactions  related to its
Canadian operations. To manage its exposure to these exchange rate fluctuations,
Valero uses foreign currency  exchange and purchase  contracts.  These contracts
are not designated as hedging instruments.

Current Period Disclosures
The  net  gain   recognized   in  income   representing   the  amount  of  hedge
ineffectiveness was as follows (in millions):

                                              Three Months Ended March 31,

The above amounts were included in cost of sales in the consolidated  statements
of income.  No  component  of the  derivative  instruments'  gains or losses was
excluded from the assessment of hedge

effectiveness.  No amounts were recognized in income for hedged firm commitments
that no longer qualify as fair value hedges.

For cash flow hedges,  gains and losses currently  reported in accumulated other
comprehensive   income  (loss)  in  the  consolidated  balance  sheets  will  be
reclassified  into income when the forecasted  transactions  affect income.  The
estimated   amount  of  existing  net  gain   included  in   accumulated   other
comprehensive  income as of March 31, 2003 that is  expected to be  reclassified
into income  within the next 12 months was $5.5  million.  As of March 31, 2003,
the maximum  length of time over which  Valero was  hedging its  exposure to the
variability in future cash flows for forecasted transactions was 21 months, with
the majority of the  transactions  maturing in less than one year. For the three
months ended March 31, 2003 and 2002,  there were no amounts  reclassified  from
accumulated  other  comprehensive  income  (loss) into income as a result of the
discontinuance of cash flow hedge accounting.

11.  SEGMENT INFORMATION

Segment information for Valero's two reportable  segments,  refining and retail,
was as follows (in millions):

Total assets by reportable segment have not changed significantly since December
31, 2002.

12.  STOCK-BASED COMPENSATION

Valero  accounts for its employee stock  compensation  plans using the intrinsic
value  method of  accounting  set forth in APB Opinion No. 25,  "Accounting  for
Stock  Issued  to  Employees,"  and  related  interpretations  as  permitted  by
Statement No. 123, "Accounting for Stock-Based Compensation."

Because  Valero  accounts for its employee  stock  compensation  plans using the
intrinsic  value  method,  no  compensation  cost  has  been  recognized  in the
consolidated  statements of income for Valero's  fixed stock option plans as all
options  granted  had an  exercise  price  equal  to  the  market  value  of the
underlying common stock on the date of grant. Had compensation cost for Valero's
fixed stock option plans been  determined  based on the grant-date fair value of
awards for the three  months ended March 31, 2003 and 2002  consistent  with the
method set forth in Statement  No. 123,  Valero's net income (loss) and earnings
(loss) per common share for the three months ended March 31, 2003 and 2002 would
have been reduced to the pro forma amounts indicated below (in millions,  except
per share amounts):

13. ENVIRONMENTAL MATTERS

Liabilities  for  future  remediation  costs  are  recorded  when  environmental
assessments and/or remedial efforts are probable and the costs can be reasonably
estimated.  Other  than for  assessments,  the  timing  and  magnitude  of these
accruals  are  generally  based on the  completion  of  investigations  or other
studies or a commitment  to a formal plan of action.  Environmental  liabilities
are  based  on best  estimates  of  probable  undiscounted  future  costs  using
currently  available  technology and applying  current  regulations,  as well as
Valero's own internal environmental policies.

The balance of and changes in the accruals for environmental  matters, which are
principally  included  in  other  long-term  liabilities,  were as  follows  (in
millions):

                                                            2003         2002
                                                            ----         ----
      Balance as of January 1.......................      $ 222.0     $ 170.8
        Additions to accrual, net...................          2.0         0.4
        Payments, net of third-party recoveries.....         (2.4)       (5.1)
                                                            -----       -----
      Balance as of March 31........................      $ 221.6     $ 166.1
                                                            =====       =====


The increase in the balance of the accrual for environmental  matters from March
31, 2002 to March 31, 2003 was due primarily to  additional  accruals to conform
the assessment of environmental  liabilities  resulting from the UDS Acquisition
by  utilizing  the same time period  over which  environmental  liabilities  are
determined under Valero's policy.

Valero believes that it has adequately provided for its environmental  exposures
with the accruals referred to above.  These liabilities have not been reduced by
potential future  recoveries from third parties.  Environmental  liabilities are
difficult to assess and estimate due to unknown factors such as the magnitude of
possible contamination,  the timing and extent of remediation, the determination
of Valero's

                                       18

                   VALERO ENERGY CORPORATION AND SUBSIDIARIES

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)


liability in proportion to other parties,  improvements in cleanup technologies,
and the extent to which  environmental  laws and  regulations  may change in the
future.

14.  COMMITMENTS AND CONTINGENCIES

Guarantees
In  connection  with the sale of the Golden Eagle  Business,  Valero  guaranteed
certain lease payment  obligations  related to an MTBE facility lease assumed by
Tesoro Refining and Marketing Company (Tesoro),  which totaled approximately $46
million as of March 31, 2003. This lease expires in 2010.

As of March 31,  2003 and  December  31,  2002,  Valero  had  various  long-term
operating  lease  commitments  that have been funded  through  structured  lease
arrangements with non-consolidated  third-party entities. These structured lease
arrangements  provide for maximum residual value guarantees  ranging from 82% to
87% of the  appraised  value of the  leased  properties  at the end of the lease
term,  as  determined  at the  inception of the lease.  As of March 31, 2003 and
December 31, 2002, the maximum  residual value guarantee on Valero's  structured
lease   arrangements   was   approximately   $569  million  and  $541   million,
respectively.

Contingent Earn-Out Agreements
In connection with Valero's  acquisitions of Basis  Petroleum,  Inc. in 1997 and
the Paulsboro  Refinery in 1998, the sellers are entitled to receive payments in
any of the ten years and five years, respectively,  following these acquisitions
if certain average refining margins during any of those years exceed a specified
level.  Any payments due under these earn-out  arrangements are limited based on
annual and aggregate limits. No earn-out payments were made for the three months
ended March 31, 2003 and 2002.

Environmental Matters
EPA's  Tier II  Gasoline  and  Diesel  Standards.  The  EPA's  Tier II  gasoline
standard,  adopted under the Clean Air Act,  phases in limitations on the sulfur
content of gasoline beginning in 2004 and the sulfur content of diesel fuel sold
to highway consumers  beginning in 2006.  Modifications will be required at most
of Valero's refineries as a result of the Tier II gasoline and diesel standards.
Valero  believes that capital  expenditures of about $1 billion will be required
between  now and 2006 for  Valero to meet the new Tier II  specifications.  This
includes   approximately  $300  million  for  related  projects  at  two  Valero
refineries to improve  refinery yield and octane balance and to provide hydrogen
as part of the process of removing  sulfur during the production of gasoline and
diesel. Valero expects that such estimates will change as additional engineering
analyses are completed and progress is made toward construction of these various
projects.  Factors  that will affect the impact of these  regulations  on Valero
include Valero's ultimate selection of specific technologies to meet the Tier II
standards and  uncertainties  related to timing,  permitting and construction of
specific units. Valero expects to meet all Tier II gasoline and diesel standards
by their respective effective dates, both in the U.S. and Canada.

EPA's Section 114 Initiative.  In 2000, the EPA issued to a majority of refiners
operating  in the United  States a series of  information  requests  pursuant to
Section 114 of the Clean Air Act as part of an  enforcement  initiative.  Valero
received a Section 114 information  request  pertaining to all of its refineries
owned at that time.  Valero has completed  its response to the request.  Several
other refiners have reached  settlements with the EPA regarding this enforcement
initiative. Though Valero has not been named in any proceeding, it also has been
discussing the possibility of settlement with the EPA regarding

                                       19

                   VALERO ENERGY CORPORATION AND SUBSIDIARIES

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)


this initiative.  Based in part upon announced settlements and evaluation of its
relative  position,  Valero expects to incur  penalties and related  expenses in
connection with a potential  settlement of this enforcement  initiative.  Valero
believes  that any  potential  settlement  penalties  will be  immaterial to its
financial position.  However, Valero believes that any potential settlement with
the EPA in this matter will require various  capital  improvements or changes in
operating  parameters,  or both, at some or all of its refineries which could be
material in the aggregate.

Houston/Galveston SIP. Valero's Houston and Texas City Refineries are located in
the  Houston/Galveston  area which is classified as "severe  nonattainment"  for
compliance  with EPA  air-quality  standards for ozone. In October 2001, the EPA
approved a State Implementation Plan (SIP) to bring the  Houston/Galveston  area
into compliance with the EPA's ozone  standards by 2007. The  EPA-approved  plan
was based on a requirement for industry  sources to reduce emissions of nitrogen
oxides (NOx) by 90%.  Certain  industry and business groups  challenged the plan
based on technical  feasibility of the 90% NOx control and its  effectiveness in
meeting  the  ozone  standard.   In  December  2002,  the  Texas  Commission  on
Environmental    Quality   (TCEQ)   adopted   a   revised   approach   for   the
Houston/Galveston  SIP. This  alternative  plan requires an 80% reduction in NOx
emissions  and a 64% reduction in so-called  highly  reactive  volatile  organic
compounds  (HRVOC).  This  alternative  plan  is  subject  to EPA  scrutiny  and
approval. Valero's Texas City and Houston Refineries will be required to install
NOx and HRVOC control and monitoring  equipment and practices by 2007, at a cost
estimated by Valero to be  approximately  $60 million based on the proposed TCEQ
approach.

MTBE Restrictions. The presence of MTBE in some water supplies in California and
other states,  resulting from gasoline  leaks  primarily  from  underground  and
aboveground  storage tanks, has led to public concern that MTBE poses a possible
health  risk.  As a result  of  heightened  public  concern,  California  passed
initiatives to ban the use of MTBE as a gasoline  component in California by the
end of 2003. The California Air Resources Board's  specifications for CARB Phase
III gasoline will become  effective at the beginning of 2004.  Valero  estimates
that the cost to permit and modify its California refineries to comply with CARB
Phase III gasoline  specifications and eliminate MTBE as a gasoline component is
approximately  $60 million.  In  addition,  other states and the EPA have either
passed or proposed or are  considering  proposals  to restrict or ban the use of
MTBE.  If MTBE were to be  restricted or banned  throughout  the United  States,
Valero believes that its major non-California MTBE-producing facilities could be
modified to produce other octane enhancing  products for a capital investment of
approximately $35 million. This  minimum-investment case assumes a conversion of
MTBE-producing    facilities    to    produce    iso-octene,    a    high-octane
low-vapor-pressure  gasoline  blending  component.  Valero  will  also  evaluate
alternative  conversion cases that may involve higher capital  commitments,  but
will be justified on the basis of improved operating income.

Litigation
Unocal
In 2002,  Union Oil Company of California  (Unocal) sued Valero  alleging patent
infringement.  The  complaint  seeks  a 5.75  cent  per  gallon  royalty  on all
reformulated  gasoline  infringing  on  Unocal's  '393 and '126  patents.  These
patents cover certain  compositions of cleaner-burning  gasoline.  The complaint
seeks  treble  damages for Valero's  alleged  willful  infringement  of Unocal's
patents and Valero's  alleged  conduct to induce others to infringe the patents.
In a previous lawsuit  involving its '393 patent,  Unocal prevailed against five
other major refiners.  In 2001, the Federal Trade  Commission began an antitrust
investigation  concerning  Unocal's conduct with a joint industry research group
during the time that

                   VALERO ENERGY CORPORATION AND SUBSIDIARIES

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)


Unocal was  prosecuting  its  patents at the U.S.  Patent and  Trademark  Office
(PTO).  On March 4,  2003,  the FTC  announced  that it was  filing a  complaint
against Unocal for antitrust violations. The FTC's complaint seeks an injunction
against any future patent enforcement activity by Unocal. This matter is set for
trial  beginning  in November  2003.  Each of the '393 and '126 patents is being
reexamined by the PTO. The PTO has issued  notices of rejection of all claims of
each of these patents.  These rejections are subject to additional  proceedings,
including  administrative  appeal by  Unocal,  followed  by an appeal in federal
district  court or the court of appeals.  Ultimate  invalidation  would preclude
Unocal from pursuing  claims based on the '393 or '126 patents.  Unocal's patent
lawsuit  against  Valero  is  indefinitely   stayed  as  a  result  of  the  PTO
reexamination  proceedings.  Notwithstanding  the  judgment  against  the  other
refiners in the previous litigation,  Valero believes that it has several strong
defenses to Unocal's lawsuit,  including those arising from Unocal's misconduct,
and Valero believes it will prevail in the lawsuit. However, due to the inherent
uncertainty of  litigation,  there can be no assurance that Valero will prevail,
and an adverse result could have a material  adverse effect on Valero's  results
of operations and financial position.

MTBE Litigation
Valero  is  a  defendant  in  various  cases  alleging  MTBE   contamination  in
groundwater in New York and  California.  The plaintiffs  generally  allege that
refiners  and   manufacturers  of  gasoline   containing  MTBE  are  liable  for
manufacturing a defective product.  In California,  the lawsuits have been filed
by local  water  providers,  including  the City of  Santa  Monica,  the City of
Dinuba,  Fruitridge Vista Water Company and the Orange County Water District. In
New York, a lawsuit has been filed by the Suffolk County Water Authority.  These
cases are primarily based on a product  liability/product defect theory and seek
individual,  unquantified compensatory and punitive damages and attorneys' fees.
Valero  believes it is unlikely that the final outcome of any one of these suits
filed by local  water  providers  would  have a material  adverse  effect on its
results of operations  or financial  position,  but that an adverse  result in a
majority of these cases could have a material adverse effect on Valero's results
of operations and financial position.

Other Claims
Valero is also a party to additional claims and legal proceedings arising in the
ordinary  course of  business.  Valero  believes it is  unlikely  that the final
outcome of any of the claims or  proceedings to which it is a party would have a
material  adverse  effect on its  financial  position,  results of operations or
liquidity;  however, due to the inherent uncertainty of litigation, the range of
possible loss, if any, cannot be estimated with a reasonable degree of precision
and there can be no assurance  that the  resolution of any  particular  claim or
proceeding  would not have an adverse effect on Valero's  results of operations,
financial position or liquidity.

15.  SUBSEQUENT EVENTS

Plan to Divest of Heating Oil Business
On April 8,  2003,  Valero  announced  a plan to  divest  its home  heating  oil
businesses in the areas of New England and Southern Ontario, Canada. Valero will
retain its home  heating  oil  business  in the areas of  Northern  and  Eastern
Ontario and the Atlantic provinces. The decision to divest was based on Valero's
ongoing  efforts to improve  efficiency in its operations and to concentrate its
home  heating oil  business  operations  in regions  closer to  Valero's  Quebec
Refinery  where they are more highly  integrated  with Valero's  other  business
activities. No loss is expected to be incurred on the disposition.

                   VALERO ENERGY CORPORATION AND SUBSIDIARIES

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)


Exercise of Overallotment Option
On April 11, 2003,  the  underwriters  of the common unit offering  discussed in
Note 3 elected to exercise their option to purchase  581,000  additional  common
units of Valero L.P. On April 16,  2003,  Valero L.P.  closed on the exercise of
the  overallotment  option which reduced Valero's  ownership of Valero L.P. from
49.5% to 48.2%.

Cash Dividends
On April 24, 2003, Valero's Board of Directors declared a regular quarterly cash
dividend of $0.10 per common share payable June 11, 2003 to holders of record at
the close of business on May 27, 2003.

Proposed Acquisition of Orion Refinery
On May 14,  2003,  Valero  announced  that it had entered  into an  agreement to
purchase Orion Refining  Corporation's  (Orion)  refinery located in St. Charles
Parish, Louisiana,  approximately 15 miles west of New Orleans. The refinery has
a total throughput capacity of approximately 185,000 barrels per day (bpd) and a
crude oil  capacity  of  approximately  155,000  bpd.  Approximately  74% of the
refinery's  product  slate is composed of gasoline,  distillate  and other light
products.   The  purchase   price  for  the  refinery  is  $400  million,   plus
approximately  $100  million  for working  capital,  payable in the form of $250
million of mandatory  convertible  preferred  stock and the balance in cash. The
convertible  preferred  stock  will have a stated  value of $25.00 per share and
will automatically convert to Valero common stock in three years.

The purchase  agreement for the refinery  also  provides for potential  earn-out
payments if agreed-upon  refining  margins reach a specified level during any of
the seven years following the closing.  The earn-out  payments are subject to an
annual maximum limit of $50 million and an aggregate limit of $175 million.

The  acquisition  has been approved by the board of directors of both Valero and
Orion. However, because Orion filed for bankruptcy on May 13, 2003, Orion's sale
of the  refinery  requires  the  approval  of the  bankruptcy  court.  Orion has
petitioned  the  court  for an  expedited  sales  process  and if  granted,  the
transaction,  which has already received Federal Trade Commission  approval,  is
expected to close during the second quarter of 2003,  unless a higher and better
bid is received, in which case a break-up fee payable to Valero could apply.

Item 2. Management's  Discussion and Analysis of Financial Condition and Results
of Operations

FORWARD-LOOKING STATEMENTS

This Form 10-Q,  including  without  limitation the  discussion  below under the
heading  "Results  of  Operations  -  Outlook,"   contains  certain   estimates,
predictions, projections, assumptions and other "forward-looking statements" (as
defined in Section  27A of the  Securities  Act of 1933 and  Section  21E of the
Securities  Exchange Act of 1934) that involve various risks and  uncertainties.
While these forward-looking  statements, and any assumptions upon which they are
based, are made in good faith and reflect  Valero's  current judgment  regarding
the direction of its business, actual results will almost always vary, sometimes
materially, from any estimates, predictions,  projections,  assumptions or other
future performance  suggested in this report. These  forward-looking  statements
can  generally be  identified by the words  "anticipate,"  "believe,"  "expect,"
"plan," "intend," "estimate,"  "project," "budget," "forecast," "will," "could,"
"should,"  "may"  and  similar  expressions.  These  forward-looking  statements
include, among other things, statements regarding:

     o    future refining margins, including gasoline and heating oil margins;
     o    future retail margins,  including  gasoline,  diesel, home heating oil
          and convenience store merchandise margins;
     o    expectations  regarding feedstock costs, including crude oil discounts
          and operating expenses;
     o    anticipated levels of crude oil and refined product inventories;
     o    Valero's anticipated level of capital investments,  including deferred
          refinery  turnaround and catalyst costs and capital  expenditures  for
          environmental  and other  purposes,  and the  effect of those  capital
          investments on Valero's results of operations;
     o    anticipated trends in the supply of and demand for crude oil and other
          feedstocks  and  refined  products  in the United  States,  Canada and
          elsewhere;
     o    expectations regarding environmental and other regulatory initiatives;
          and
     o    the effect of general  economic and other  conditions  on refining and
          retail industry fundamentals.

Valero's  forward-looking  statements  are based on its beliefs and  assumptions
derived  from  information  available  at the  time  the  statements  are  made.
Differences between actual results and any future performance suggested in these
forward-looking statements could result from a variety of factors, including the
following:

     o    acts of  terrorism  aimed  at  either  Valero's  facilities  or  other
          facilities  that could  impair  Valero's  ability  to  produce  and/or
          transport refined products or receive foreign feedstocks;
     o    political  conditions  in crude oil producing  regions,  including the
          Middle East and South America;
     o    the  domestic  and  foreign  supplies  of  refined  products  such  as
          gasoline, diesel fuel, jet fuel, home heating oil and petrochemicals;
     o    the domestic and foreign supplies of crude oil and other feedstocks;
     o    the ability of the members of the Organization of Petroleum  Exporting
          Countries  (OPEC)  to agree on and to  maintain  crude  oil  price and
          production controls;
     o    the level of consumer demand, including seasonal fluctuations;
     o    refinery overcapacity or undercapacity;
     o    the  actions  taken by  competitors,  including  both  pricing and the
          expansion and  retirement  of refining  capacity in response to market
          conditions;
     o    environmental  and other  regulations  at both the  state and  federal
          levels and in foreign countries;
     o    the level of foreign imports of refined products;
     o    accidents   or  other   unscheduled   shutdowns   affecting   Valero's
          refineries,  machinery,  pipelines or equipment,  or those of Valero's
          suppliers or customers;



                                       23

     o    changes in the cost or availability of  transportation  for feedstocks
          and refined products;
     o    the  price,  availability  and  acceptance  of  alternative  fuels and
          alternative-fuel vehicles;
     o    cancellation of or failure to implement  planned capital  projects and
          realize  the  various  assumptions  and  benefits  projected  for such
          projects  or  cost  overruns  in  constructing  such  planned  capital
          projects;
     o    earthquakes,  hurricanes,  tornadoes and irregular weather,  which can
          unforeseeably  affect the price or  availability of natural gas, crude
          oil and other feedstocks and refined products;
     o    rulings,  judgments or  settlements  in  litigation  or other legal or
          regulatory matters,  including  unexpected  environmental  remediation
          costs in excess of any reserves or insurance coverage;
     o    the  introduction or enactment of federal or state  legislation  which
          may adversely affect Valero's business or operations;
     o    changes in the credit ratings assigned to Valero's debt securities and
          trade credit;
     o    changes  in the  value of the  Canadian  dollar  relative  to the U.S.
          dollar; and
     o    overall economic conditions.

Any one of these factors,  or a combination of these factors,  could  materially
affect  Valero's  future results of operations  and whether any  forward-looking
statements ultimately prove to be accurate.  Valero's forward-looking statements
are not  guarantees  of  future  performance,  and  actual  results  and  future
performance may differ  materially  from those suggested in any  forward-looking
statements.  Valero  does not  intend to update  these  statements  unless it is
required by the securities laws to do so.

All  subsequent  written and oral  forward-looking  statements  attributable  to
Valero or persons acting on its behalf are expressly qualified in their entirety
by the foregoing. Valero undertakes no obligation to publicly release the result
of any  revisions  to any such  forward-looking  statements  that may be made to
reflect events or circumstances  after the date of this report or to reflect the
occurrence of unanticipated events.

The following notes relate to references on pages 25 through 28.
(a)  On March 18, 2003,  Valero's  ownership  interest in Valero L.P.  decreased
     from 73.6% to 49.5%.  As a result of this  decrease in  ownership of Valero
     L.P. combined with certain other  partnership  governance  changes,  Valero
     ceased consolidating Valero L.P. as of that date and began using the equity
     method to account for its investment in the partnership.
(b)  A  reconciliation  of the  amounts  used for the  calculation  of EBITDA is
     included in "Results of Operations - Corporate Expenses and Other."
(c)  The ratio of EBITDA to  interest  incurred  is a  non-GAAP  measure  and is
     calculated  by dividing  EBITDA by interest  and debt  expense  incurred as
     reflected in the consolidated statements of income.
(d)  Throughput  margin per barrel  represents  operating  revenues less cost of
     sales divided by throughput  volumes.
(e)  The Gulf Coast refining  region  includes the Corpus  Christi,  Texas City,
     Houston,  Three  Rivers and Krotz  Springs  Refineries;  the  Mid-Continent
     refining  region  includes the McKee,  Ardmore and Denver  Refineries;  the
     Northeast refining region includes the Quebec and Paulsboro Refineries; and
     the  West  Coast  refining  region  includes  the  Benicia  and  Wilmington
     Refineries.
(f)  The average market reference prices and  differentials,  with the exception
     of the  propylene  and lube oil  differentials,  are based on posted prices
     from  Platt's  Oilgram.  The  propylene  differential  is based  on  posted
     propylene  prices in  Chemical  Market  Associates,  Inc.  and the lube oil
     differential  is based on Exxon  Mobil  Corporation  postings  provided  by
     Independent Commodity Information  Services-London Oil Reports. The average
     market  prices and  differentials  are  presented  to provide  users of the
     consolidated   financial   statements   with   economic   indicators   that
     significantly affect Valero's operations and profitability.
(g)  The market  reference  differential for sour crude oil is based on 50% Arab
     Medium and 50% Arab Light posted prices.

General

Valero's  net  income  for the three  months  ended  March 31,  2003 was  $170.4
million,  or $1.51 per share,  compared to a net loss of $38.6 million, or $0.37
per share, for the three months ended March 31, 2002.

Operating  revenues  increased 73% for the first quarter of 2003 compared to the
first  quarter of 2002  primarily as a result of  significantly  higher  refined
product  prices  combined  with  additional  throughput  volumes  from  refinery
operations.  Operating income increased $357.9 million from the first quarter of
2002 to the  first  quarter  of 2003 due to a  $328.6  million  increase  in the
refining segment and a $43.4 million  increase in the retail segment,  partially
offset by a $14.1 million increase in administrative expenses.

Refining

Operating income for Valero's  refining segment increased from $62.1 million for
the first  quarter  of 2002 to $390.7  million  for the first  quarter  of 2003,
resulting  primarily from an increase in refining throughput margin of $2.35 per
barrel,  or 69%.  The  increase in  throughput  margin was due to the  following
factors:
     o    Refined product inventories  declined sharply during the first quarter
          of 2003 as a result of the oil  workers'  strike in  Venezuela,  which
          caused many refiners to reduce production due to uneconomic  operating
          conditions.   In  addition  to  the  strike,   the  refining  industry
          experienced  one of the  heaviest  maintenance  turnaround  periods in
          recent history,  which  contributed to low refinery  utilization rates
          and lower  production of refined  products.  Continued  strong product
          demand,  especially in the Northeast due to the colder winter weather,
          also contributed to lower refined product inventories.
     o    Average  gasoline  margins  increased  more than 40%  across  Valero's
          refining system as inventories  declined and demand  remained  strong.
          Distillate margins also increased due



                                      28

          primarily  to the  colder  winter  weather in the  Northeast  and fuel
          switching demand caused by high natural gas prices.
     o    Refinery  throughput  volumes  increased for the first quarter of 2003
          compared  to the first  quarter of 2002 for all of  Valero's  refining
          regions despite reduced  production in January 2003.  During the first
          quarter of 2002, seven of Valero's twelve  refineries were affected by
          scheduled  turnaround  activities and production at several refineries
          was cut by as much as 25% due to  uneconomic  operating  conditions in
          January and February of 2002.

Refining operating expenses were 27% higher for the quarter ended March 31, 2003
compared to the quarter  ended March 31,  2002 due  primarily  to higher  energy
costs and, to a lesser extent, increases in variable compensation,  maintenance,
insurance  and ad valorem  taxes.  However,  due to an  increase  in  throughput
volumes,  the  operating  cost increase on a per barrel basis was 13%, or $0.30,
between the periods.

Retail

Retail  operating  income was $46.8 million for the quarter ended March 31, 2003
compared to $3.4 million for the quarter  ended March 31, 2002.  The increase in
retail operating  income was primarily  related to higher retail fuel margins in
both the U.S. and Northeast retail systems.

Corporate Expenses and Other

Administrative  expenses increased $16.5 million for the quarter ended March 31,
2003 compared to the quarter  ended March 31, 2002.  The increase was due mainly
to the recognition of variable compensation expense of approximately $11 million
in 2003 in anticipation of the payment of year-end bonuses for 2003. No variable
compensation  expense was  recognized  during the first  quarter of 2002 because
Valero reported a net loss for the period.

Equity in earnings of Valero L.P.  represents  Valero's  equity  interest in the
earnings  of Valero L.P.  after  March 18,  2003.  On March 18,  2003,  Valero's
ownership  interest in Valero L.P. decreased from 73.6% to 49.5%. As a result of
this  decrease  in  ownership  of  Valero  L.P.   combined  with  certain  other
partnership  governance changes,  Valero ceased  consolidating Valero L.P. as of
that date and began  using the equity  method to account for its  investment  in
Valero L.P.

Other  income,  net decreased  $2.5 million.  The decrease was due mainly to the
recognition  of an asset  retirement  obligation  of $4.2 million as required by
FASB Statement No. 143,  "Accounting for Asset  Retirement  Obligations,"  which
Valero adopted  effective  January 1, 2003,  partially offset by $2.5 million of
interest income on the notes  receivable from Tesoro in connection with the sale
of the Golden Eagle Business in the second quarter of 2002.

Net interest  and debt expense  increased  $20.5  million for the quarter  ended
March 31, 2003  compared  to the quarter  ended March 31, 2002 due mainly to the
issuance  of  approximately  $2 billion of  fixed-rate  debt  during  2002 at an
average rate of approximately 7%, which replaced a majority of the floating-rate
debt  outstanding  as of March 31, 2002.  The effect of the  increased  interest
rates was partially  offset by lower average  borrowings in the first quarter of
2003 and  certain new  interest  rate swap  agreements  which  reduced  interest
expense by $2.8 million for the first quarter of 2003.

Income tax expense  increased  $127.6  million from the first quarter of 2002 to
the first quarter of 2003 mainly as a result of higher operating income.

Valero's  rationale  for using the  financial  measure of  EBITDA,  which is not
defined  under  United  States  generally  accepted  accounting  principles,  is
discussed in Valero's Annual Report on Form 10-K for the year ended December 31,
2002.

OUTLOOK

The refining and  marketing  industry has been and  continues to be volatile and
highly  competitive.  As a result of the  historic  volatility  of refining  and
retail  margins and the fact that they are affected by numerous  factors,  it is
difficult to predict future margin levels.

At the end of the first  quarter of 2003,  gasoline and  distillate  inventories
were lower than  year-ago  levels and  five-year  average  levels due to various
factors,  including the Venezuelan oil workers' strike, a significant  number of
industry-wide  maintenance  turnarounds  in  the  first  quarter,  cold  weather
experienced in late winter in the  northeastern  part of the United States,  and
fuel switching due to high natural gas prices. These low inventories resulted in
a strong margin  environment during the second half of the first quarter of 2003
and through April 2003. In addition,  the strong  distillate demand that existed
in the first quarter of 2003 has continued thus far in the second  quarter,  due
mainly to continued fuel switching caused by high natural gas prices despite the
end of colder winter weather.  Gasoline demand is also expected to remain strong
as pump  prices have  recently  declined  and many people are  choosing to drive
rather than fly for shorter trips. Sour crude oil discounts widened early in the
second quarter of 2003; however, the loss of Iraqi sour crude oil from the world
market and lower OPEC sour crude oil output have caused sour crude oil discounts
to recently  narrow.  Valero expects these discounts to widen as more sour crude
oil, particularly from Iraq, returns to the market over the next few months.

LIQUIDITY AND CAPITAL RESOURCES

Cash Flows for the Three Months Ended March 31, 2003 and 2002
Net cash provided by operating  activities  was $503.2  million during the first
quarter of 2003  compared  to net cash used in  operating  activities  of $178.8
million during the first quarter of 2002. The $682.0 million favorable change in
cash generated from operating activities was due primarily to:
o    The  significant  increase in  operating  income for the reasons  discussed
     above under "Results of Operations" and
o    $135.0 million of cash generated from changes in working capital during the
     first quarter of 2003 while $189.7 million was required for working capital
     purposes  during  the  first  quarter  of 2002,  the  detail  for  which is
     reflected in Note 9 of Notes to Consolidated  Financial Statements for both
     periods.

The  favorable  change  in  working  capital  in the first  quarter  of 2003 was
attributable  to an  increase  in  accounts  payable  resulting  from  increased
inventory  volumes and an increase in  commodity  prices from  December  2002 to
March 2003.  The  increase in accounts  payable was offset to a large  extent by




                                       30


increases in  receivables  and  inventories  for the same reasons.  The net cash
generated from operating  activities combined with approximately $250 million of
proceeds  from the  issuance  of common  stock in March  2003,  $350  million of
proceeds  from the sale of certain  assets to Valero L.P. as discussed in Note 3
of Notes to Consolidated  Financial Statements,  $137 million resulting from the
redemption  of Valero L.P.  common  units held by Valero which was funded with a
portion of the proceeds  from a $250 million debt  offering by Valero L.P.,  and
$30.5  million of proceeds from the issuance of common stock related to Valero's
benefit  plans  were used to:
     o    repay  debt  and  capital  lease  obligations  of  approximately  $700
          million,
     o    fund capital  investments of $155.2 million and  acquisitions of $15.1
          million, and
     o    pay  common  stock  dividends.
In addition, Valero's cash balance increased by $362.0 million from December 31,
2002 to March 31, 2003.

As  discussed  above,  net cash used in  operating  activities  during the first
quarter of 2002 was $178.8  million,  of which  $189.7  million was required for
working capital  purposes,  largely resulting from a net increase in receivables
and  accounts  payable  attributable  to an  increase in  commodity  prices from
December  2001 to March 2002. In addition,  accrued  expenses  decreased  $206.6
million resulting mainly from payments of  change-in-control  benefits to former
UDS employees and employee  bonuses.  These working  capital  requirements  were
partially  offset by a reduction in income taxes  receivable of $112.9  million.
During the quarter  ended March 31,  2002,  Valero  received  $300.9  million of
proceeds  as  a  result  of  the  liquidation  of  Valero's  investment  in  the
Diamond-Koch  joint venture.  These proceeds,  combined with bank borrowings and
borrowings  under Valero's $1.5 billion  bridge loan, the  utilization of excess
cash,  and proceeds from  issuances of common stock related to Valero's  benefit
plans, were used to:
     o    fund the $2.1 billion cash payment to UDS  shareholders  in connection
          with the UDS Acquisition,
     o    fund capital  expenditures  of $193.4 million and deferred  turnaround
          and catalyst costs of $77.4 million,
     o    fund  $86.0  million of net cash  flows  related  to the Golden  Eagle
          Business,
     o    provide cash required for operating activities as discussed above,
     o    repurchase shares of Valero common stock, and
     o    pay common stock dividends.

Capital Investments
During the three months ended March 31, 2003,  Valero  expended  $127.9  million
related to capital expenditures and $27.3 million related to deferred turnaround
and catalyst costs.  Capital  expenditures  for the three months ended March 31,
2003 included  $44.2 million for  construction  of new gasoline  desulfurization
units at the Texas City,  Paulsboro and Corpus Christi Refineries in response to
new low-sulfur regulations.

In connection with Valero's  acquisitions of Basis  Petroleum,  Inc. in 1997 and
the Paulsboro  Refinery in 1998, the sellers are entitled to receive payments in
any of the ten years and five years, respectively,  following these acquisitions
if certain average refining margins during any of those years exceed a specified
level.  Any payments due under these earn-out  arrangements are limited based on
annual and aggregate  limits.  Based on actual margin levels  through April 2003
and estimated margin levels through  mid-September  2003,  earn-out  payments of
approximately  $35 million and $20  million,  respectively,  would be due to the
sellers during 2003.

For 2003,  Valero  expects  to incur  approximately  $1.1  billion  for  capital
investments,   including  approximately  $1  billion  for  capital  expenditures
(approximately  $500  million  of  which  is  for  environmental  projects)  and
approximately  $100 million for deferred  turnaround  and  catalyst  costs.  The



                                       31


capital  expenditure  estimate  excludes  approximately  $150  million  and  $60
million,  respectively,  related to a coker  facility at the Texas City Refinery
and the planned expansion of the former UDS headquarters facility, which will be
Valero's new corporate  headquarters.  The coker and headquarters facilities are
being funded through  structured  lease  arrangements.  The capital  expenditure
estimate also excludes  anticipated  expenditures of  approximately  $55 million
related to the earn-out contingency agreements discussed above, the funding of a
proposed crude oil pipeline construction project through a joint venture with El
Paso Energy Partners L.P. of approximately $110 million, and the purchase of one
of Valero's current  headquarters  buildings in April 2003 for approximately $23
million  that  was  previously  under a  structured  lease  arrangement.  Valero
continuously  evaluates  its  capital  budget  and  makes  changes  as  economic
conditions warrant.

Contractual Obligations
Valero's  contractual   obligations  include  obligations  for  long-term  debt,
operating  leases,   purchase   obligations  and   company-obligated   preferred
securities of subsidiary trusts.  There have been no significant  changes in the
terms of Valero's  contractual  obligations  during the quarter  ended March 31,
2003. None of Valero's agreements have rating agency triggers that would require
Valero to post additional  collateral.  However,  in the event of a downgrade by
the rating agencies,  borrowings under some of Valero's bank credit  facilities,
structured leases and other arrangements  would become more expensive.  On March
6, 2003,  Moody's  Investors'  Service  downgraded its rating of Valero's senior
unsecured debt to Baa3 with a stable outlook from Baa2 with a negative  outlook.
The reduction was  attributed  to high debt levels,  expectations  regarding the
sustainability of refining margins, and Valero's aggressive growth strategy.  On
March 10, 2003,  Standard & Poor's  Ratings  Services  reaffirmed  its rating on
Valero's senior unsecured debt at BBB with a negative outlook.

Valero's  company-obligated  preferred  securities of subsidiary  trusts include
$172.5  million of 7 3/4%  Premium  Equity  Participating  Security  Units (PEPS
Units) (6.9 million units at $25.00 per unit).  In August 2003,  pursuant to the
purchase contract that is part of each PEPS Unit, the holders of PEPS Units will
be obligated to purchase shares of common stock from Valero for $25 per purchase
contract,  which will result in the receipt of $172.5  million of cash by Valero
in  exchange  for the  issuance  of  common  stock at a price  based on a 20-day
trading  period.  Holders of PEPS Units may settle their  purchase  contracts by
paying cash to Valero or by remarketing their pledged trust preferred securities
and using the proceeds from the  remarketing  to settle the purchase  contracts.
The distribution rate on the trust preferred  securities will be reset on August
18,  2003  based on the  price for which  the  trust  preferred  securities  are
remarketed.

Other Commercial Commitments
As of March 31, 2003, Valero's committed lines of credit included (in millions):

                                                Borrowing
                                                 Capacity           Expiration
                                                 --------           ----------
     364-day revolving credit facility......        $ 750.0       November 2003
     5-year revolving credit facility.......        $ 750.0       December 2006
     Canadian revolving credit facility.....    Cdn $ 115.0         July 2005

Under Valero's revolving bank credit facilities, Valero's debt-to-capitalization
ratio (net of cash) was  approximately 41% as of March 31, 2003. For purposes of
this  computation,  50% of the $200 million of 8.32% Trust Originated  Preferred
Securities  assumed  in the UDS  Acquisition  and 20% of the  $172.5  million of
aggregate liquidation amount of trust preferred securities issued as part of the
PEPS Units were included as debt.




                                       32

As of March 31, 2003, Valero had $167.1 million of letters of credit outstanding
under its  uncommitted  short-term  bank credit  facilities,  $168.4  million of
letters of credit  outstanding  under its  committed  facilities  and Cdn.  $6.4
million of letters of credit outstanding under its Canadian facility.

Valero  believes  it has  sufficient  funds from  operations,  and to the extent
necessary, from the public and private capital markets and bank markets, to fund
its  ongoing  operating  requirements.   Valero  expects  that,  to  the  extent
necessary,  it can raise  additional  funds from time to time through  equity or
debt financings.  However, there can be no assurances regarding the availability
of any future  financings or whether such  financings  can be made  available on
terms acceptable to Valero.

Valero L.P.
Effective March 18, 2003,  Valero L.P.  redeemed 3.8 million of its common units
from  Valero  for  $137.0  million  (including  $2.9  million  representing  the
redemption of a proportionate amount of Valero's general partner interest),  the
proceeds of which were used by Valero to reduce bank  borrowings.  Also on March
18, 2003, Valero received $350 million from the contribution by Valero to Valero
L.P. of certain  storage tanks and a refined  products  pipeline  system.  These
transactions are discussed further in Note 3 of Notes to Consolidated  Financial
Statements.

Environmental Matters
Valero is subject to extensive federal,  state and local  environmental laws and
regulations,  including  those  relating to the discharge of materials  into the
environment, waste management, pollution prevention measures and characteristics
and  composition of gasoline and  distillates.  Because  environmental  laws and
regulations are becoming more complex and stringent and new  environmental  laws
and regulations are continuously being enacted or proposed,  the level of future
expenditures  required for environmental matters will increase in the future. In
addition,  any  major  upgrades  in any of  Valero's  refineries  could  require
material   additional   expenditures  to  comply  with  environmental  laws  and
regulations.   For  additional   information  regarding  Valero's  environmental
matters, see Note 14 of Notes to Consolidated Financial Statements.

OFF-BALANCE SHEET ARRANGEMENTS

Structured Lease Arrangements
Valero has various  long-term  operating lease commitments that have been funded
through   structured  lease  arrangements  with   non-consolidated   third-party
entities.  After the initial lease term, the leases may be extended by agreement
of the parties.  The various structured lease arrangements also permit Valero to
sell the leased  properties to a third party,  in which case the leases  provide
for maximum residual value  guarantees  ranging from 82% to 87% of the appraised
value of the leased  properties  at the end of the lease term,  as determined at
the inception of the lease.  As of March 31, 2003,  the maximum  residual  value
guarantee on Valero's  structured  lease  arrangements  was  approximately  $569
million.

Valero uses these structured lease arrangements to provide additional  liquidity
to fund its  ongoing  operations.  Except for the  purchase  of one of  Valero's
current headquarters buildings for approximately $23 million that was subject to
a lease that  expired in April 2003 and the  potential  purchase of  convenience
stores for  approximately  $215  million  under  leases which expire in July and
December 2003,  Valero  believes that it is not  reasonably  likely that it will
purchase  these  leased  assets at any time  during  their lease terms and would
likely  renew,  to the extent  that it can,  the leases  for such  assets  under
similar  arrangements.  Note 2 of Notes  to  Consolidated  Financial  Statements
contains a discussion of FASB Interpretation No. 46,  "Consolidation of Variable
Interest Entities."


                                       33


Guarantees
In  connection  with the sale of the Golden Eagle  Business,  Valero  guaranteed
certain lease payment  obligations  related to an MTBE facility lease assumed by
Tesoro, which totaled approximately $46 million as of March 31, 2003. This lease
expires in 2010.

CRITICAL ACCOUNTING POLICIES

The  preparation  of  financial  statements  in  accordance  with United  States
generally accepted  accounting  principles requires management to make estimates
and assumptions that affect the amounts  reported in the consolidated  financial
statements  and  accompanying  notes.  Actual  results  could  differ from those
estimates.  Valero's critical  accounting  policies were disclosed in its Annual
Report on Form 10-K for the year ended December 31, 2002. The following  summary
provides  further  information  about  changes in Valero's  critical  accounting
policies.

Asset Retirement Obligations
Effective  January 1, 2003,  Valero adopted  Statement No. 143,  "Accounting for
Asset  Retirement  Obligations,"  which  established  accounting  standards  for
recognition  and measurement of a liability for an asset  retirement  obligation
and the associated  asset  retirement  cost. The provisions of Statement No. 143
apply to legal obligations associated with the retirement of tangible long-lived
assets that result from the acquisition, construction, or development and/or the
normal  operation of a long-lived  asset. An entity is required to recognize the
fair value of a liability  for an asset  retirement  obligation in the period in
which it is incurred if a  reasonable  estimate of fair value can be made.  If a
reasonable  estimate  of fair  value  cannot  be made in the  period  the  asset
retirement  obligation is incurred,  the liability  should be recognized  when a
reasonable estimate of fair value can be made.

In order to determine  fair value,  management  must make certain  estimates and
assumptions   including,   among  other   things,   projected   cash  flows,   a
credit-adjusted  risk-free  rate,  and an assessment of market  conditions  that
could  significantly  impact the  estimated  fair value of the asset  retirement
obligation. These estimates and assumptions are very subjective. However, Valero
believes it has adequately  accrued for its asset  retirement  obligations.  See
Note 2 of Notes to Consolidated  Financial  Statements for an explanation of the
effect of Valero's adoption of Statement No. 143.

Item 3.  Quantitative and Qualitative Disclosures About Market Risk

COMMODITY PRICE RISK

The following tables provide  information  about Valero's  derivative  commodity
instruments  as of March 31, 2003 and  December  31, 2002  (dollars in millions,
except for the  weighted-average  pay and receive  prices as  described  below),
including:
     o    fair value hedges held to hedge refining  inventories and unrecognized
          firm commitments,
     o    cash  flow  hedges  held to  hedge  forecasted  feedstock  or  product
          purchases and refined product sales,
     o    economic hedges held to:
          o    manage price volatility in refined product inventories, and
          o    manage price volatility in forecasted feedstock,  natural gas and
               refined product purchases, and
     o    trading activities held or issued for trading purposes.

Contract  volumes  are  presented  in  thousands  of barrels  (for crude oil and
refined products) or in billions of British thermal units (for natural gas). The
weighted-average pay and receive prices represent amounts




                                       34


per barrel (for crude oil and refined  products) or amounts per million  British
thermal units (for natural  gas).  Volumes  shown for swaps  represent  notional
volumes, which are used to calculate amounts due under the agreements.  The gain
(loss) on swaps is equal to the fair value amount and  represents  the excess of
the receive price over the pay price times the notional  contract  volumes.  For
futures and options, the gain (loss) represents (i) the excess of the fair value
amount over the contract  amount for long  positions,  or (ii) the excess of the
contract  amount over the fair value amount for short  positions.  Additionally,
for futures and options,  the weighted-average pay price represents the contract
price for long positions and the  weighted-average  receive price represents the
contract  price  for  short  positions.   The  weighted-average  pay  price  and
weighted-average receive price for options represents their strike price.

INTEREST RATE RISK

The following  table  provides  information  about  Valero's  long-term debt and
interest rate derivative  instruments (in millions,  except interest rates), all
of which are  sensitive  to changes  in  interest  rates.  For  long-term  debt,
principal  cash flows and related  weighted-average  interest  rates by expected
maturity  dates are  presented.  For  interest  rate swaps,  the table  presents
notional amounts and weighted-average  interest rates by expected  (contractual)
maturity dates.  Notional amounts are used to calculate the contractual payments
to be exchanged under the contract. Weighted-average floating rates are based on
implied forward rates in the yield curve at the reporting date.

FOREIGN CURRENCY RISK

Valero enters into foreign  currency  exchange and purchase  contracts to manage
its  exposure to  exchange  rate  fluctuations  on  transactions  related to its
Canadian  operations.  During May 2002,  Valero  entered into  foreign  currency
exchange  contracts to hedge its exposure to exchange  rate  fluctuations  on an
investment in its Canadian operations.  Under these contracts,  Valero sold $400
million of Canadian  dollars and bought $253.4  million of U.S.  dollars.  As of
March 31, 2003 and December 31, 2002, these contracts had a fair value of $(5.3)
million and $6.1  million,  respectively.  For the three  months ended March 31,
2003,  Valero  recognized  an $11.7 million loss on these  contracts,  which was
offset by a gain of $12.5  million  recognized  in income from the effect of the
exchange rate  fluctuation on the hedged asset for the quarter.  As of March 31,
2003, $202.5 million of these contracts remain outstanding and mature as follows

Item 4.  Controls and Procedures

         (a)  Evaluation of disclosure controls and procedures.

         Valero's  principal  executive officer and principal  financial officer
have evaluated Valero's  disclosure  controls and procedures (as defined in Rule
13a-14(c) under the Securities Exchange Act of 1934) as of a date within 90 days
of the  filing  date of  this  quarterly  report  on Form  10-Q.  Based  on that
evaluation,  these officers  concluded that the design and operation of Valero's
disclosure  controls and procedures  are effective in ensuring that  information
required to be disclosed by Valero in the reports that it files or submits under
the Exchange Act is recorded,  processed,  summarized  and reported,  within the
time periods  specified in the  Securities and Exchange  Commission's  rules and
forms.

         (b)  Changes in internal controls.

         There have been no significant  changes in Valero's internal  controls,
or  in  other  factors  that  could  significantly   affect  internal  controls,
subsequent to the date of the certifying  officers'  certifications  pursuant to
Rule 13a-14  included with  Valero's  Form 10-K for the year ended  December 31,
2002.


PART II - OTHER INFORMATION

Item 1. Legal Proceedings

New Jersey Department of Environmental  Protection (NJDEP) (Paulsboro  Refinery)
(this matter was last  reported in Valero's  Annual  Report on Form 10-K for the
year  ended  December  31,  2002).  Since July 2002,  Valero has  received  five
Administrative Orders and Notices of Civil Administrative Penalty Assessments in
the aggregate  amount of $390,300 from the NJDEP.  The penalties are for alleged
failures to repair  certain leak  detection  points in the  refinery  within the
15-day regulatory deadline for repairs, and are based on multiple inspections of
the  refinery  by NJDEP  during  the  fourth  quarter of 1999 and from the first
through the fourth quarter of 2002. The last notice and order from the NJDEP was
received by



                                       38

Valero on March 31, 2003. Valero has asserted certain defenses to the Orders and
has taken certain corrective actions with respect to these incidents.

Item 5.  Other Information

Proposed Acquisition of Orion Refinery

On May 14,  2003,  Valero  announced  that it had entered  into an  agreement to
purchase Orion Refining  Corporation's  (Orion)  refinery located in St. Charles
Parish, Louisiana,  approximately 15 miles west of New Orleans. The refinery has
a total throughput capacity of approximately 185,000 barrels per day (bpd) and a
crude oil  capacity  of  approximately  155,000  bpd.  Approximately  74% of the
refinery's  product  slate is composed of gasoline,  distillate  and other light
products.   The  purchase   price  for  the  refinery  is  $400  million,   plus
approximately  $100  million  for working  capital,  payable in the form of $250
million of mandatory  convertible  preferred  stock and the balance in cash. The
convertible  preferred  stock  will have a stated  value of $25.00 per share and
will automatically convert to Valero common stock in three years. The conversion
ratio for determining the number of shares of Valero common stock to be received
upon  conversion of the preferred  stock will be $25.00  divided by Valero's per
share common  stock price at  conversion,  subject to a maximum and minimum.  If
Valero's  common stock price at  conversion is less than or equal to the average
or  "notional"  price of Valero's  common stock during a 20  trading-day  period
prior to issuance of the  preferred  stock,  then the  conversion  ratio will be
equal to $25 divided by the notional  price.  If Valero's  common stock price at
conversion is greater than 1.35 times the notional price, then the ratio will be
equal to $25  divided  by the  product  of 1.35 times the  notional  price.  The
preferred  holders may convert  the  preferred  stock at any time at the minimum
conversion ratio. The preferred stock will have a non-cumulative coupon equal to
2% per annum, paid quarterly.

The purchase  agreement for the refinery  also  provides for potential  earn-out
payments if agreed-upon  refining  margins reach a specified level during any of
the seven years following the closing.  The earn-out  payments are subject to an
annual maximum limit of $50 million and an aggregate limit of $175 million.

The  acquisition  has been approved by the board of directors of both Valero and
Orion. However, because Orion filed for bankruptcy on May 13, 2003, Orion's sale
of the  refinery  requires  the  approval  of the  bankruptcy  court.  Orion has
petitioned  the  court  for an  expedited  sales  process  and if  granted,  the
transaction,  which has already received Federal Trade Commission  approval,  is
expected to close during the second quarter of 2003,  unless a higher and better
bid is received, in which case a break-up fee payable to Valero could apply.
