                   VALERO ENERGY CORPORATION AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1. BASIS OF PRESENTATION, PRINCIPLES OF CONSOLIDATION AND SIGNIFICANT ACCOUNTING
   POLICIES


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.

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 six months ended June 30, 2003 are not
necessarily  indicative  of the results that may be expected for the year ending
December 31, 2003.

The consolidated 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.

Revenues for products sold by both the refining and retail segments are recorded
upon  delivery of the products to their  customers,  which is the point at which
title to the products is transferred,  and when payment has either been received
or collection is reasonably assured. Revenues for services are recorded when the
services have been provided.

Valero  evaluates its equity method  investments  for  impairment  when there is
evidence  that  it may  not be  able  to  recover  the  carrying  amount  of its
investments  or the  investee  is unable to sustain an  earnings  capacity  that
justifies the carrying  amount.  A loss in the value of an investment,  which is
other than a temporary  decline,  is  recognized  currently in earnings,  and is
based  on the  difference  between  the  estimated  current  fair  value  of the
investment and its carrying value. As of June 30, 2003, Valero believed that the
value of its equity method investments was not impaired.

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  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

                   VALERO ENERGY CORPORATION AND SUBSIDIARIES

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

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 a  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.  As of June 30, 2003, the changes in Valero's asset retirement
obligation were as follows (in millions):

           Balance as of January 1, 2003................   $ 30.0
            Accretion expense...........................      0.9
            Foreign currency translation................      1.9

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 15. 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. During the first

                   VALERO ENERGY CORPORATION AND SUBSIDIARIES

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

six months of 2003,  the  adoption  of FIN 45 did not have a material  effect on
Valero's financial position and results of operations.

FASB Interpretation No. 46
In January 2003, the FASB issued Interpretation No. 46 (FIN 46),  "Consolidation
of Variable Interest  Entities." FIN 46 requires the consolidation of a variable
interest entity (VIE) in which an enterprise  absorbs a majority of the entity's
expected  losses and/or  receives a majority of the entity's  expected  residual
returns as a result of ownership, contractual or other financial interest in the
entity. Prior to the issuance of FIN 46, an entity was generally consolidated by
an enterprise when the enterprise had a controlling  financial  interest through
ownership of a majority voting interest in the entity.

FIN 46 was  immediately  applicable to VIE's created after January 31, 2003, and
to VIE's in which an enterprise  obtained an interest after that date.  However,
for VIE's created before February 1, 2003, FIN 46 first became  applicable as of
the first fiscal year or interim period  beginning  after June 15, 2003.  Valero
has held  variable  interests  in VIE's that were  created  prior to February 1,
2003,  but it has not obtained  any  variable  interests in VIE's during the six
months ended June 30, 2003.

Valero had  various  long-term  operating  lease  commitments  that were  funded
through   structured  lease  arrangements  with   non-consolidated   third-party
entities.  These lease agreements provided 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.  Prior to
June 30, 2003,  Valero  exercised  its purchase  option under three such leases,
purchasing  one of its current  headquarters  buildings and certain  convenience
stores as  discussed  further  in Note 15.  The  remaining  leased  assets  were
acquired  by a single  financial  institution  which has been deemed not to be a
VIE.  Accordingly,  the  provisions  of FIN 46 do not apply to these  structured
lease arrangements.

Valero has investments in 50% or less owned entities (including joint ventures),
which are accounted for currently  using the equity method of accounting.  Under
FIN 46, Valero's joint venture interests and its other contractual relationships
with the joint  ventures  represent  variable  interests in the joint  ventures;
however,  Valero is not the primary beneficiary of any of the joint ventures. As
a result, Valero will not consolidate the joint ventures beginning July 1, 2003,
but will  continue to account for its joint venture  interests  under the equity
method.

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,

                                       9


                   VALERO ENERGY CORPORATION AND SUBSIDIARIES

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

     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.

Valero will adopt the provisions of Statement No. 149 for  derivative  contracts
entered into or modified  after June 30, 2003. No impact is expected on Valero's
financial  position  or  results  of  operations  as a result of  adopting  this
statement.

FASB Statement No. 150
In May  2003,  the FASB  issued  Statement  No.  150,  "Accounting  for  Certain
Financial Instruments with Characteristics of both Liabilities and Equity." This
statement  establishes  standards  for how an  issuer  classifies  and  measures
certain  financial  instruments  with  characteristics  of both  liabilities and
equity.  It  requires  that an issuer  classify a financial  instrument  that is
within its scope as a liability  because that financial  instrument  embodies an
obligation of the issuer.  Statement  No. 150 requires  three types of financial
instruments to be accounted for as liabilities:
     o    mandatorily redeemable financial instruments,
     o    obligations to repurchase the issuer's  equity shares by  transferring
          assets, and
     o    obligations  that must or may be settled  with  shares,  the  monetary
          value of which is (a) fixed,  (b) tied to a variable  such as a market
          index, or (c) varies inversely with the value of the issuer's shares.
Statement  No.  150 is  effective  for  financial  instruments  entered  into or
modified after May 31, 2003,  and otherwise  shall be effective at the beginning
of the first  interim  period  beginning  after June 15,  2003.  Valero does not
expect that the adoption of this statement will result in any significant effect
on its financial position or 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 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, excluding the
units held by affiliates of Valero.  As a result of the issuance and  redemption

                   VALERO ENERGY CORPORATION AND SUBSIDIARIES

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

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 West,
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 East, Corpus Christi West
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 $181.8  million  for  Valero.  Due to  Valero's  continuing  ownership
interest  in Valero  L.P.,  $90.0  million  of this  excess  was  recorded  as a
reduction to Valero's  investment in Valero L.P. and will be amortized  over the
lives of the  contributed  assets.  The remaining $91.8 million was deferred and
recorded in other  long-term  liabilities and will be amortized over the life of
the  throughput,   handling,  terminalling  and  service  agreements,  which  is
approximately 10 years.

No  immediate  gain was  recognized  as a result of the  transactions  discussed
above.

Financial information reported by Valero L.P. is summarized below (in millions):

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)


In connection with the contribution of the crude oil and intermediate  feedstock
storage tanks and the three-pipeline system discussed above, Valero entered into
certain  throughput,  handling,  terminalling and service agreements with Valero
L.P. In addition,  Valero has other related party  transactions with Valero L.P.
for the use of Valero  L.P.'s  pipelines,  terminals  and crude oil storage tank
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 and maintenance services provided by Valero to Valero L.P.

On April 16, 2003, 581,000 additional common units of Valero L.P. were issued as
a result of the exercise by the underwriters of a portion of their overallotment
option  related to the March 18, 2003 common unit  issuance,  reducing  Valero's
ownership from 49.5% to 48.2%.

4. INVENTORIES

Inventories consisted of the following (in millions):

                                                  June 30,         December 31,

As of June 30, 2003 and December 31, 2002, the replacement cost of Valero's LIFO
inventories  exceeded their LIFO carrying values by  approximately  $475 million
and $586 million, respectively.

5.   GOODWILL

All of Valero's  goodwill has been  allocated  among four  reporting  units that
comprise  the  refining  segment.  Those  reporting  units  are the Gulf  Coast,
Mid-Continent, Northeast and West Coast refining regions.

The carrying value of goodwill decreased from December 31, 2002 to June 30, 2003
due  mainly  to  the  reclassification  of  the  goodwill  related  to  Valero's
investment in Valero L.P. as a result of Valero ceasing  consolidation of Valero

                   VALERO ENERGY CORPORATION AND SUBSIDIARIES

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)


L.P. as discussed in Note 3. This decrease in goodwill was  partially  offset by
an  earn-out  payment of $35.0  million  related to the  acquisition  from Basis
Petroleum, Inc. in 1997, as discussed in Note 15.

6.   LONG-TERM  DEBT AND  COMPANY-OBLIGATED  PREFERRED  SECURITIES OF SUBSIDIARY
     TRUSTS

On June 4, 2003,  Valero  issued  $300  million of 4.75% notes due June 15, 2013
under its shelf registration statement.  Interest is payable semi-annually.  The
notes are unsecured and are redeemable, in whole or in part, at Valero's option.
The net proceeds from this  offering of $296.8  million were used to redeem $200
million of 8.32% Trust  Originated  Preferred  Securities and $100 million of 8%
debentures  due 2023.  A premium of $3.8  million  was paid and  expensed in the
second quarter of 2003 as a result of the early redemption of the 8% debentures.

7.   CAPITAL LEASE OBLIGATIONS

On February 28, 2003, Valero exercised its option to purchase the Corpus Christi
East Refinery and related refined product  logistics  business,  which have been
operated  by Valero  since June 1, 2001 under its  capital  leases  with El Paso
Corporation.  In  connection  with the  exercise  of the  purchase  option,  the
original  purchase price for the assets was reduced by  approximately $5 million
to $289.3 million and the lease payment of  approximately  $5 million due in the
first  quarter  of 2003  was  avoided.  No gain or  loss  was  recorded  on this
transaction.

8.   STOCKHOLDERS' EQUITY

Common Stock Offering
On March 28,  2003,  Valero  issued 6.3 million  shares of its common stock at a
price of $40.25 per share and  received net  proceeds of $250.2  million.  These
shares were issued under Valero's  universal shelf registration  statement.  The
proceeds were used for repayment of borrowings  under  Valero's  revolving  bank
credit facilities.

Common Stock Repurchase Programs
Under common stock repurchase  programs approved by Valero's Board of Directors,
Valero  repurchases  shares  of its  common  stock  from time to time for use in
connection with its employee benefit plans and other general corporate purposes.
During the six months ended June 30, 2003 and 2002, Valero repurchased shares of
its common  stock  under  these  programs  at a cost of $19.7  million and $44.0
million, respectively.

In order to determine net cash provided by (used in) operating  activities,  net
income is adjusted by, among other things, changes in current assets and current

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 six months ended June 30, 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,  goodwill,  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 six months ended June 30, 2002 included:
     o    an  adjustment  to  goodwill  and assets  held for sale to reflect the
          difference  between  estimated  and actual  proceeds  received  on the
          liquidation of the investment in  Diamond-Koch  and the disposition of
          the Golden Eagle Business;
     o    the receipt of $150.0  million of notes from Tesoro with an  estimated
          fair value of $58.9 million in connection  with the disposition of the
          Golden Eagle Business; and

11.  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  (loss)  recognized  in  income  representing  the  amount of hedge
ineffectiveness was as follows (in millions):

       Fair value hedges..........      $ (5.4)       $ 1.5        $ (1.6)       $   3.0
       Cash flow hedges...........         3.3         (2.5)          4.0           12.4


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 June 30, 2003 that is  expected  to be  reclassified
into income  within the next 12 months was $14.0  million.  As of June 30, 2003,
the maximum  length of time over which  Valero was  hedging its  exposure to the
variability in future cash flows for forecasted transactions was 18 months, with
the  majority of the  transactions  maturing in less than one year.  For the six
months  ended June 30, 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.

13.  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 and six months ended June 30, 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 and six months  ended June 30,
2003 and 2002 would have been reduced to the pro forma amounts  indicated  below
(in millions, except per share amounts):

14.  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.........................         6.6              1.4
    Payments, net of third-party recoveries......        (4.9)           (13.0)
                                                        -----            -----
   Balance as of June 30.........................     $ 223.7          $ 159.2
                                                        =====            =====

The increase in the balance of the accrual for  environmental  matters from June
30, 2002 to June 30, 2003 was due  primarily to  additional  accruals to conform
the assessment of environmental liabilities resulting from the UDS Acquisition
by  utilizing  the  same  twenty-year  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

                   VALERO ENERGY CORPORATION AND SUBSIDIARIES

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)


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

15.  COMMITMENTS AND CONTINGENCIES

Structured Lease Arrangements
As of June 30,  2003  and  December  31,  2002,  Valero  had  various  long-term
operating  lease   commitments   that  were  funded  through   structured  lease
arrangements with  non-consolidated  third-party entities. In the second quarter
of 2003, Valero purchased one of its current headquarters  buildings and certain
convenience stores for approximately $23 million and $215 million, respectively,
which were  subject to  structured  lease  arrangements.  Of the payment for the
convenience   stores,   approximately  $127  million  was  recorded  as  capital
expenditures  and   approximately  $88  million  reduced  an  unfavorable  lease
obligation that was recorded in conjunction with the UDS Acquisition.

Accounts Receivable Sales Facility
As of December 31, 2002, Valero had an accounts receivable sales facility with a
third-party  financial  institution  to sell  on a  revolving  basis  up to $250
million of eligible trade and credit card receivables,  which matures in October
2005. In June 2003, Valero amended its agreement to add two additional financial
institutions  to the program and to  increase  the size of its  facility by $350
million to $600 million. Under this program, wholly owned subsidiaries of Valero
sell an undivided  percentage  ownership  interest in the eligible  receivables,
without  recourse,  to the third-party  financial  institutions.  Valero remains
responsible  for servicing  the  transferred  receivables  and pays certain fees
related to its sale of receivables  under the program.  As of June 30, 2003, the
amount of eligible  receivables sold to the third-party  financial  institutions
was $600 million.

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 $40
million as of June 30, 2003. This lease expires in 2010.

Valero's  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 June 30, 2003 and December 31, 2002,  the maximum  residual  value
guarantee under Valero's  structured lease  arrangements was approximately  $398
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.  In May 2003 and 2002,  Valero  made an  earn-out
contingency  payment to Salomon Inc in connection  with Valero's  acquisition of
Basis Petroleum, Inc. of $35.0 million and $23.9 million, respectively.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)


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 $1.2 billion,  after giving
effect to the  acquisition  of the St.  Charles  Refinery (see Note 16), will be
required  through 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 from  gasoline  and diesel.  Valero
expects that such estimates  will change as additional  engineering is 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 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


                                       21

                   VALERO ENERGY CORPORATION AND SUBSIDIARIES

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)


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 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 anitrust  violations.  The FTC's complaint seeks an
injunction  against  any future  '393 and '126  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,  it is  reasonably
possible  that  Valero will not prevail in the  lawsuit,  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 or agencies,  including the City of Santa Monica,  the
City of Dinuba,  Fruitridge  Vista  Water  Company and the Orange  County  Water
District.  In New York,  lawsuits  have been filed by the Suffolk  County  Water
Authority and by certain  residents who own retail  stations in Dutchess  County
(who seek  certification  as a class).  These  cases  are  primarily  based on a
product  liability/product  defect  theory  and  seek  individual,  unquantified
compensatory  and  punitive  damages and  attorneys'  fees.  Although an adverse


                                       22


                   VALERO ENERGY CORPORATION AND SUBSIDIARIES

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)


result in one or more of these suits is  reasonably  possible,  Valero  believes
that such an outcome in any one of these suits would not have a material adverse
effect on its results of  operations  or  financial  position.  However,  Valero
believes  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.

16.  SUBSEQUENT EVENTS

Acquisition of St. Charles Refinery
On May 13, 2003,  Valero entered into an agreement to purchase  Orion's refinery
located in St. Charles  Parish,  Louisiana,  approximately  15 miles west of New
Orleans.  The refinery's name has been changed to the St. Charles  Refinery.  On
July 1, 2003,  Valero  completed the purchase of the St. Charles  Refinery.  The
purchase  price for the  refinery  was $400  million,  plus  $148.4  million for
refinery hydrocarbon  inventories based on market prices at the time of closing.
Consideration for the purchase, including various transaction costs incurred and
warehouse  inventories  acquired,  consisted of $307.6  million in cash and $250
million  face value of 2%  mandatory  convertible  preferred  stock (10  million
shares with a stated value of $25.00 per share),  of which $21.1 million is held
in escrow  pending the  satisfaction  of certain  conditions  stipulated  in the
purchase  agreement.  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 mandatory  convertible  preferred stock will automatically convert to Valero
common stock on July 1, 2006. Valero will pay annual dividends of $0.50 for each
share of  convertible  preferred  stock  when and if  declared  by its  board of
directors.  Dividends will be paid  quarterly,  provided that dividends will not
accrue or be payable  with respect to a  particular  calendar  quarter if Valero
does not declare a dividend on its common  stock during that  calendar  quarter.
The  convertible  preferred  stock will rank with respect to dividend rights and
rights upon Valero's  liquidation,  winding-up or  dissolution  as follows:  (i)
senior to all common stock and to all other  capital  stock of Valero  issued in
the future  that ranks  junior to the  convertible  preferred  stock;  (ii) on a
parity  with any of  Valero's  capital  stock  issued in the future the terms of
which  expressly  provide  that it will  rank on a parity  with the  convertible
preferred  stock; and (iii) junior to all of Valero's capital stock the terms of
which  expressly  provide  that  such  capital  stock  will  rank  senior to the
convertible preferred stock.

                   VALERO ENERGY CORPORATION AND SUBSIDIARIES

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)


Upon automatic  conversion of the  convertible  preferred stock on July 1, 2006,
the  number  of  shares  of  common  stock  to be  received  for  each  share of
convertible  preferred  stock  shall be based on the  average  closing  price of
Valero's  common  stock  over the  20-day  trading  period  ending on the second
trading day prior to July 1, 2006 as follows:
     o    0.6690  shares if the average  closing price is less than or equal to
          $37.37;
     o    a number of shares  having a value of  $25.00 if the  average  closing
          price is between $37.37 and $50.45; or
     o    0.4955 shares if the average closing price is greater than $50.45.
Each share of convertible  preferred stock is convertible,  at the option of the
holder,  at any time  before July 1, 2006 into  0.4955  shares of Valero  common
stock. On July 11, 2003, Valero filed a registration  statement on Form S-3 with
the  Securities  and  Exchange  Commission  (SEC) to register  the 2%  mandatory
convertible preferred stock and the common stock issuable upon the conversion of
the convertible preferred stock.

Cameron Highway Oil Pipeline Project
On July 14, 2003,  Valero  completed  agreements with GulfTerra Energy Partners,
L.P. (GulfTerra,  formerly El Paso Energy Partners,  L.P.) to form a 50/50 joint
venture in the Cameron Highway Oil Pipeline  Project.  The project  involves the
construction  and operation of a 390-mile crude oil pipeline that is expected to
deliver  up to  500,000  barrels  per day from the Gulf of  Mexico  to the major
refining  areas of Port Arthur and Texas City,  Texas.  GulfTerra will build and
operate the pipeline, which is scheduled for completion during the third quarter
of 2004.  Valero's  total  equity  investment  in the project is estimated to be
approximately $110 million,  approximately $100 million of which will be paid in
2003.

Cash Dividends
On July 17, 2003,  Valero's Board of Directors declared a regular quarterly cash
dividend  of $0.10 per common  share  payable  September  10, 2003 to holders of
record at the close of business on August 13, 2003.

Company-Obligated Preferred Securities of a Subsidiary Trust
Valero's company-obligated  preferred securities of a subsidiary trust represent
$172.5  million of 7 3/4%  Premium  Equity  Participating  Security  Units (PEPS
Units)  (6.9  million  units at $25.00 per unit).  The PEPS Units were issued in
2000 by Valero under a shelf registration  statement.  Upon issuance,  each PEPS
Unit  consisted  of a trust  preferred  security  issued  by VEC  Trust I and an
associated  purchase contract obligating the holder of the PEPS Unit to purchase
on August 18,  2003 a number of shares of common  stock from  Valero for $25 per
purchase contract.  The settlement of 6.9 million purchase contracts will result
in the issuance of approximately  4.9 million shares of Valero common stock at a
price based on the average price of Valero common stock for the relevant  20-day
trading period. Under the original agreement, holders of PEPS Units could 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. In accordance with the original agreement, the
distribution  rate on the trust  preferred  securities was to be reset on August
18,  2003  based on the price for which  the  trust  preferred  securities  were
remarketed.  In  accordance  with the terms of the trust,  on August  12,  2003,
Valero  dissolved the trust and substituted its senior  deferrable notes for the
trust preferred securities.  As a result,  Valero's senior deferrable notes were
scheduled to be remarketed in place of the trust preferred securities,  with the
interest  rate on the senior  deferrable  notes to be reset on August  18,  2003
based upon the price for which the senior deferrable notes are remarketed.

                   VALERO ENERGY CORPORATION AND SUBSIDIARIES

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)


The  remarketing  of the senior  deferrable  notes was  scheduled for August 13,
2003. The holders of approximately 6.36 million PEPS Units opted to settle their
purchase  contract  obligations  by  remarketing  the  senior  deferrable  notes
(totaling $159 million),  while holders of approximately 0.54 million PEPS Units
elected to settle their purchase contract obligations with cash and retain their
senior deferrable notes (totaling $13.6 million) in lieu of participating in the
remarketing.  On August 13, Valero received  notice from the  remarketing  agent
that a failed  remarketing  of the  senior  deferrable  notes was deemed to have
occurred.  The $159 million of senior  deferrable notes surrendered to Valero to
satisfy the holders' purchase contract obligations will be retained by Valero in
full satisfaction of the holders'  obligations under the purchase  contracts and
will be canceled  on August 18,  2003.  The  remaining  $13.6  million of senior
deferrable notes will remain  outstanding for their remaining two-year term, and
the interest rate for these notes will be 6.797%.

Valero L.P. Common Unit Offering
On August 11, 2003,  Valero L.P.  closed on a public  offering of common  units,
selling  1,236,250 common units,  which includes 161,250 common units related to
the overallotment option, to the public at $41.15 per unit, before underwriter's
discount  of $1.85  per  unit.  In  order to  maintain  its 2%  general  partner
interest,  Valero  contributed  $1.0  million to Valero L.P. As a result of this
common unit  offering,  Valero now owns 45.8% of Valero L.P.,  including  the 2%
general partner interest.

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

     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;

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;



                                       26


     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;

          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

Valero  markets  refined  products  through an extensive bulk and rack marketing
network and a network of approximately 4,000 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.

General

Valero's net income for the three months ended June 30, 2003 was $128.4 million,
or $1.08 per share, compared to net income of $11.3 million, or $0.10 per share,
for the three months ended June 30, 2002.

Operating  revenues increased 22% for the second quarter of 2003 compared to the
second quarter of 2002  primarily as a result of higher  refined  product prices
combined with additional throughput volumes from refinery operations.  Operating
income  increased  $174.3  million from the second quarter of 2002 to the second

                                       32



quarter of 2003 due to a $161.0 million  increase in the refining  segment and a
$27.0  million  increase  in the  retail  segment,  partially  offset by a $13.7
million increase in administrative  expenses (including related depreciation and
amortization expense).

Refining

Operating income for Valero's refining segment increased from $118.2 million for
the second  quarter of 2002 to $279.2  million  for the second  quarter of 2003,
resulting from a 14% increase in throughput  volumes and an increase in refining
throughput margin of $0.85 per barrel, or 22%.

The increase in throughput margin in 2003 was due to the following factors:
     o    Discounts  on  Valero's  sour crude oil  feedstocks  during the second
          quarter of 2003  almost  doubled  from very weak second  quarter  2002
          levels.  Sour crude oil discounts in the 2002 quarter were unfavorably
          impacted by crude oil production cuts by OPEC and limited availability
          of Iraqi sour crude oil on the world  market.  Even  though sour crude
          oil  discounts  improved in 2003  compared  to 2002,  removal of Iraqi
          crude oil from the market  caused  discounts  to  decrease  during the
          latter part of the second quarter of 2003.
     o    Distillate   margins   in  the  second   quarter  of  2003,   although
          considerably  weaker than the first quarter,  improved relative to the
          very low margins experienced in the second quarter of 2002. Margins in
          the 2002 quarter were abnormally low due to weak economic  conditions,
          an unusually warm winter in the northeastern part of the United States
          and in Europe,  and lower jet fuel demand  following the September 11,
          2001 terrorist attacks.
     o    CARB gasoline  margins improved in the second quarter of 2003 compared
          to the second quarter of 2002 due mainly to the unfavorable  effect on
          margins  in 2002 of an  unusually  high  level of  production  of CARB
          gasoline in California.
     o    During  the  second  quarter of 2002,  production  at ten of  Valero's
          refineries  was  cut due to  uneconomic  operating  conditions,  which
          resulted in lower-than-normal throughput volumes in 2002.

Partially offsetting the above increases in throughput margin was a reduction of
approximately $20 million due to Valero ceasing  consolidation of Valero L.P. in
March 2003 and the effect of significantly more unplanned downtime in the second
quarter of 2003, largely due to the following:
     o    The Ardmore Refinery  conducted a major  turnaround  during the second
          quarter  of 2003  that  was  extended  seven  days  due to  delays  in
          start-up.  Shortly  after  start-up,  tornado  activity  in  the  area
          resulted  in  a  total  refinery  power  outage,   which  damaged  the
          refinery's  sulfur  recovery unit.  The repair to the sulfur  recovery
          unit  required a complete  shutdown of the refinery for an  additional
          ten days during the second quarter of 2003.
     o    The  Texas  City  Refinery   experienced  a  delayed  restart  of  its
          residfiner following a scheduled outage in the second quarter of 2003,
          which reduced production rates.
     o    Production  at the  Benicia  Refinery  was reduced in May and June for
          repairs on the hydrocracker and the fluid catalytic cracking units.

Refining  operating expenses were 13% higher for the quarter ended June 30, 2003
compared to the quarter ended June 30, 2002 due primarily to higher  maintenance
expenses  associated  with the  unplanned  downtime  discussed  above and higher
energy costs (mainly  attributable to an increase in natural gas prices) and, to
a lesser extent, increases in employee compensation. However, due to an increase
in  throughput  volumes,  the  operating  costs on a per barrel basis  decreased
slightly between the periods.

                                       33


Retail

Retail  operating  income was $74.4  million for the quarter ended June 30, 2003
compared to $47.4 million for the quarter  ended June 30, 2002.  The increase in
retail operating income was primarily due to a record quarterly operating income
contribution  of $53.1  million  from  the U.S.  retail  operations,  despite  a
decrease in the number of company-operated  fuel sites by almost 200 sites. Fuel
margins and fuel volumes  were higher in the second  quarter of 2003 in both the
U.S. and Northeast retail systems.

Corporate Expenses and Other

Administrative  expenses  increased $12.9 million for the quarter ended June 30,
2003 compared to the quarter ended June 30, 2002. The increase was due mainly to
approximately  $8  million  related  to  employee   compensation  and  benefits,
including variable  compensation expense of $4.2 million in 2003 in anticipation
of the payment of year-end  bonuses for 2003. No variable  compensation  expense
was  recognized  during the second  quarter of 2002 as a  year-to-date  loss was
recorded  by Valero.  In  addition,  approximately  $5  million  of expense  was
recorded  during the second quarter of 2003 to increase  environmental  reserves
for certain non-operating sites and to provide for certain litigation costs.

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.  In April  2003,  Valero's  ownership  interest  in Valero L.P.  was
further  reduced  to 48.2% as a result of the  issuance  of  581,000  additional
common units of Valero L.P. upon the exercise by the  underwriters  of a portion
of their  overallotment  option  related  to the  March  18,  2003  common  unit
issuance.

Other income, net decreased $8.0 million due mainly to an increased loss of $5.7
million related to foreign currency exchange contracts and the payment of a $3.8
million  premium  associated  with the  early  redemption  in June  2003 of $100
million of 8% debentures which were due in 2023.

Net interest and debt expense  decreased $9.1 million for the quarter ended June
30, 2003  compared to the  quarter  ended June 30,  2002.  During  2002,  Valero
incurred  $5.7 million of interest  expense  under  capital  leases with El Paso
Corporation  for the Corpus Christi East Refinery and related  refined  products
logistics  business.  In February  2003,  Valero  exercised its option under the
capital  leases to purchase  the  refinery  and related  logistics  business and
therefore no further interest expense was incurred during the quarter ended June
30,  2003  related to the capital  leases.  Also during  2002,  $2.2  million of
unamortized  debt costs  associated with the bridge loan used to finance the UDS
Acquisition  was  expensed  after $1.8  billion  of notes  were  issued to repay
borrowings  under the bridge loan.  Interest  expense for the second  quarter of
2003 also  decreased from the second quarter of 2002 by $0.8 million as a result
of the  deconsolidation  of Valero L.P. in March 2003 and by $1.0 million due to
the  addition of $292  million of  interest  rate swaps which are used to manage
Valero's fixed to floating interest rate position.

Income tax expense  increased  $71.5 million from the second  quarter of 2002 to
the second quarter of 2003 mainly as a result of higher operating income.

General

Valero's net income for the six months  ended June 30, 2003 was $298.8  million,
or $2.59 per share, compared to a net loss of $27.3 million, or $0.26 per share,
for the six months ended June 30, 2002.

Operating revenues increased 45% for the six months ended June 30, 2003 compared
to the six months  ended June 30, 2002  primarily  as a result of  significantly
higher refined product prices combined with additional  throughput  volumes from
refinery  operations.  Operating  income increased $532.2 million from the first

                                       39


six  months  of 2002 to the first  six  months  of 2003 due to a $495.1  million
increase  in the  refining  segment and a $70.4  million  increase in the retail
segment, partially offset by a $33.3 million increase in administrative expenses
(including related depreciation and amortization expense).

Refining

Operating income for Valero's refining segment increased from $174.8 million for
the six months  ended June 30, 2002 to $669.9  million for the six months  ended
June 30, 2003,  resulting from a 13% increase in refining throughput volumes and
a 44% increase in refining throughput margin per barrel.

The increase in throughput margin was due to the following factors:
     o    Gasoline and distillate  margins  increased in the first six months of
          2003  compared to the same period in 2002 due to good demand and lower
          inventory  levels.  Demand for distillates  improved  significantly in
          2003 due to colder winter  weather in the Northeast and fuel switching
          demand caused by high natural gas prices.  Refined product inventories
          were lower than the high  inventory  levels  that  existed  during the
          first six months of 2002 due to the good  demand  combined  with lower
          refinery production rates resulting from a large number of maintenance
          turnarounds in the refining  industry in the first quarter of 2003 and
          the continuing impact of the oil workers' strike in Venezuela in early
          2003,  which  caused  many  refiners  to  reduce   production  due  to
          uneconomic  operating  conditions.  The high inventory  levels in 2002
          were caused by weak economic  conditions,  an unusually warm winter in
          the  northeastern  part of the United States and in Europe,  and lower
          jet fuel demand following the September 11, 2001 terrorist attacks.
     o    Discounts on Valero's sour crude oil feedstocks  increased for the six
          months  ended June 30,  2003  compared to the first six months of 2002
          due  mainly  to  weak  discounts  in 2002  resulting  from  crude  oil
          production  cuts by OPEC and limited  availability of Iraqi sour crude
          oil in the world market.
     o    Valero's  throughput  volumes for 2003 were higher than 2002, as seven
          of Valero's  refineries were affected by turnaround  activities during
          the first six months of 2002,  which  significantly  reduced  refinery
          utilization rates. Also during 2002,  production at several refineries
          was  cut by as much as 25%  due to  uneconomic  operating  conditions.
Partially  offsetting the above increases in throughput  margin were the effects
of Valero ceasing consolidation of Valero L.P. commencing in March 2003 and more
unplanned  downtime  in the first  six  months of 2003 at  certain  of  Valero's
refineries.

Refining  operating  expenses  were 20% higher for the six months ended June 30,
2003  compared  to the six months  ended June 30, 2002 due  primarily  to higher
energy costs and increases in employee compensation,  maintenance, insurance and
ad valorem taxes. Due to an increase in throughput  volumes,  the operating cost
increase on a per barrel basis was 6%, or $0.14, between the periods.

Retail

Retail  operating  income was $121.2  million for the six months  ended June 30,
2003  compared to $50.8  million  for the six months  ended June 30,  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  $34.9 million for the six months ended June
30, 2003  compared to the six months ended June 30,  2002.  The increase was due
mainly to the recognition of variable  compensation expense of approximately $15
million in 2003 in anticipation of the payment of year-end  bonuses for 2003. No
variable compensation expense was recognized during the first six months of 2002

                                       40


because Valero reported a net loss for the period. The remainder of the increase
was  attributable  primarily  to  increases  in  salary  and  benefits  expense,
litigation costs and  environmental  reserves  related to certain  non-operating
sites.

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.  In April  2003,  Valero's  ownership  interest  in Valero L.P.  was
further  reduced  to 48.2% as a result of the  issuance  of  581,000  additional
common units of Valero L.P. upon the exercise by the  underwriters  of a portion
of their  overallotment  option  related  to the  March  18,  2003  common  unit
issuance.

Other income, net decreased $10.5 million due mainly to:
     o    an increased loss of $4.9 million related to foreign currency exchange
          contracts;
     o    the initial  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; and
     o    the  payment  of a $3.8  million  premium  associated  with the  early
          redemption  in June 2003 of $100 million of 8%  debentures  which were
          due in 2023.
These  decreases  were partially  offset by a $3.6 million  increase in 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  $11.4 million for the six months ended
June 30, 2003  compared to the six months  ended June 30, 2002 due mainly to the
issuance of $1.8 billion of fixed-rate debt during April 2002 at an average rate
of  approximately  7%,  which  replaced a  majority  of the  floating-rate  debt
outstanding  as of March 31, 2002 that  carried a lower  interest  rate,  and an
increase in average  borrowings  outstanding.  The effects of these increases in
interest expense were partially  offset by reduced  interest expense  associated
with  the  capital  leases  from El Paso  Corporation  resulting  from  Valero's
exercise in February 2003 of its option to purchase the leased assets.

Income tax expense increased $199.1 million from the first six months of 2002 to
the first six months of 2003 mainly as a result of higher operating income.

The following is a reconciliation of net income (loss) to EBITDA (in millions):

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 under the  caption  "Management's  Discussion  and  Analysis  of  Financial
Condition  and Results of  Operations - Results of Operations - 2002 Compared to
2001 - Corporate Expenses and Other".

OUTLOOK

As of early August 2003, gasoline and distillate inventories continued to remain
below  year-ago  and  five-year  average  levels.  Early in the  third  quarter,
gasoline  demand is slightly  improved  compared  to the same time in 2002,  and
gasoline  imports have moderated  from recent highs as the Euroopean  market has
strengthened. With refiners focusing on gasoline production during the remainder
of the  summer,  Valero  does not expect  distillate  inventories  to rebuild to
five-year average levels before winter.

In regard to feedstocks,  Valero's sour crude oil discounts for July narrowed to
$2.55 per  barrel,  as compared to an average of $3.88 per barrel for the second
quarter of 2003,  due to the absence of Iraqi  crude oil from the  market.  Sour
crude oil discounts  for August and September  have improved to $3.20 per barrel
and $3.68 per barrel, respectively. As a result, the sour crude oil discount for
the third  quarter is expected to average  $3.14 per barrel,  which is below the
second  quarter of 2003 level.  As world  events  stabilize  and Iraqi crude oil
exports increase further,  additional sour crude oil should return to the market
and sour crude oil discounts  are expected to continue to improve.  In addition,
natural  gas costs  have  declined  thus far in the third  quarter  from  second
quarter  levels,  which  is  expected  to lower  Valero's  feedstock  costs  and
operating expenses.

In regard to Valero's refinery operations, certain unplanned downtime that began
late in the second quarter at the Texas City and Benicia Refineries continued to
result in lower production  rates at those  refineries  through July and part of
August.  With the inclusion of the St. Charles Refinery's  throughput volumes in
the third quarter, it is expected that Valero's throughput volumes will increase
approximately 10% compared to the second quarter of 2003.

LIQUIDITY AND CAPITAL RESOURCES

Cash Flows for the Six Months Ended June 30, 2003 and 2002
Net cash provided by operating activities for the six months ended June 30, 2003
was $739.7  million  compared to $22.7 million for the six months ended June 30,
2002.  The $717.0 million  increase in cash generated from operating  activities
was due primarily to:
     o    the significant  increase in operating income as discussed above under
          "Results of Operations" and
     o    $199.4  million of cash  generated  from  changes  in working  capital
          during  2003 while  $79.4  million was  required  for working  capital
          purposes  during 2002 as described in Note 10 of Notes to Consolidated
          Financial Statements for both periods.

The  favorable  change in  working  capital  for the  first  six  months of 2003
included a decrease in  receivables  of $350 million  resulting from the sale of
additional  receivables under Valero's accounts  receivable sales program.  This
favorable change in working capital was partially offset by a 7.5 million barrel
increase in inventories  resulting somewhat from downtime experienced at certain
of Valero's  refineries in the second quarter of 2003 and seasonal  increases in
certain refined product inventories.

The net cash provided by operations  combined with approximately $300 million of
proceeds  from the  issuance  of senior  notes in June  2003,  $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.  and $137  million
resulting  from the  redemption of Valero L.P.  common units held by Valero were
used to:
     o    repay  debt  and  capital  lease  obligations  of  approximately  $700
          million,
     o    fund capital  expenditures and deferred  turnaround and catalyst costs
          of $523.9 million, earn-out payments of $35.0 million and acquisitions
          of $15.1 million,
     o    redeem  $200  million of  company-obligated  preferred  securities  of
          subsidiary trusts, and
     o    pay common stock  dividends of $22.2  million.


                                       42


In addition, Valero's cash balance increased by $318.6 million from December 31,
2002 to June 30, 2003.

During the six months ended June 30, 2002,  cash and temporary cash  investments
increased  $91.5 million as Valero  received $300.9 million from the liquidation
of its investment in the  Diamond-Koch  joint  venture,  $925.0 million from the
sale of the Golden  Eagle  Business,  and $1.8  billion  from the sale of senior
notes.  Valero used these  proceeds  together with $314.7  million of short-term
borrowings to:
     o    fund the $2.1 billion cash payment to UDS  shareholders  in connection
          with the UDS Acquisition,
     o    repay long-term debt of $547.1 million,
     o    fund capital expenditures,  deferred turnaround and catalyst costs and
          earn-out payments of $516.8 million,
     o    fund  $183.5  million  of  cash  flows  related  to the  Golden  Eagle
          Business,  primarily  capital  expenditures  and  deferred  turnaround
          costs, and
     o    pay $21.1 million of common stock dividends.

Acquisition of St. Charles Refinery
On July 1, 2003,  Valero completed the purchase of the St. Charles Refinery from
Orion. The purchase price for the refinery was $400 million, plus $148.4 million
for  refinery  hydrocarbon  inventories  based on  market  prices at the time of
closing.  Consideration for the purchase,  including  various  transaction costs
incurred and warehouse inventories acquired, consisted of $307.6 million in cash
and $250  million  face value of 2% mandatory  convertible  preferred  stock (10
million shares with a stated value of $25.00 per share),  of which $21.1 million
is held in escrow pending the satisfaction of certain  conditions  stipulated in
the purchase  agreement.  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.

On July 11, 2003, Valero filed a registration statement on Form S-3 with the SEC
to register the 2% mandatory  convertible  preferred  stock and the common stock
issuable upon the conversion of the convertible preferred stock.

Capital Investments

During the six months ended June 30, 2003,  Valero  expended  $458.5 million for
capital  expenditures  and $65.4  million for deferred  turnaround  and catalyst
costs.  Capital  expenditures for the six months ended June 30, 2003 included:
     o    approximately  $150  million  to  purchase  one  of  Valero's  current
          headquarters  buildings  and certain  convenience  stores,  which were
          previously  subject to structured lease  arrangements  (see Note 15 of
          Notes to Consolidated Financial Statements).
     o    $149.5  million  to  begin  funding   construction   of  new  gasoline
          desulfurization  units at the Texas City,  Paulsboro,  Jean Gaulin and
          Corpus   Christi  West   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.  In May 2003,  Valero made an earn-out  contingency
payment  to  Salomon  Inc in  connection  with  Valero's  acquisition  of  Basis
Petroleum,  Inc. of $35.0  million.  Based on estimated  margin  levels  through
mid-September  2003,  earn-out  payments  related to the  Paulsboro  Refinery of
approximately $8 million would be due to ExxonMobil during 2003.

                                       43


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
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 for acquisitions,  approximately
$43 million related to the earn-out contingency  agreements discussed above, the
funding of a crude oil pipeline  construction  project  through a joint  venture
with  GulfTerra  of  approximately  $100  million,  and the  purchase  of one of
Valero's  current  headquarters  buildings  and certain  convenience  stores for
approximately  $150 million that were previously  funded under  structured lease
arrangements  as discussed  above.  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 a subsidiary  trust. In February 2003, Valero exercised its option
to  purchase  the Corpus  Christi  East  Refinery  and related  refined  product
logistics business, which were operated under capital leases since June 2001. On
June 4, 2003,  Valero issued $300 million of 4.75% notes due June 15, 2013 under
its shelf registration statement.  Interest is payable semi-annually.  The notes
are unsecured and are redeemable,  in whole or in part, at Valero's option.  The
net  proceeds  from this  offering  of $296.8  million  were used to redeem $200
million of 8.32% Trust  Originated  Preferred  Securities and $100 million of 8%
debentures  due 2023.  No other  significant  changes  in the terms of  Valero's
contractual obligations occurred during the six months ended June 30, 2003.

None of Valero's agreements have rating agency triggers that would automatically
require  Valero  to post  additional  collateral.  However,  in the  event  of a
downgrade of Valero's senior  unsecured debt by both Moody's  Investors  Service
and Standard & Poor's Ratings  Services,  borrowings under some of Valero's bank
credit  facilities,  structured leases and other  arrangements would become more
expensive.

PEPS Units
Valero's company-obligated  preferred securities of a subsidiary trust represent
$172.5  million of 7 3/4%  Premium  Equity  Participating  Security  Units (PEPS
Units)  (6.9  million  units at $25.00 per unit).  The PEPS Units were issued in
2000 by Valero under a shelf registration  statement.  Upon issuance,  each PEPS
Unit  consisted  of a trust  preferred  security  issued  by VEC  Trust I and an
associated  purchase contract obligating the holder of the PEPS Unit to purchase
on August 18,  2003 a number of shares of common  stock from  Valero for $25 per
purchase contract.  The settlement of 6.9 million purchase contracts will result
in the issuance of approximately  4.9 million shares of Valero common stock at a
price based on the average price of Valero common stock for the relevant  20-day
trading period. Under the original agreement, holders of PEPS Units could 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. In accordance with the original agreement, the
distribution  rate on the trust  preferred  securities was to be reset on August
18,  2003  based on the price for which  the  trust  preferred  securities  were
remarketed.  In  accordance  with the terms of the trust,  on August  12,  2003,
Valero  dissolved the trust and substituted its senior  deferrable notes for the
trust preferred securities.  As a result,  Valero's senior deferrable notes were
scheduled to be remarketed in place of the trust preferred securities,  with the
interest  rate on the senior  deferrable  notes to be reset on August  18,  2003
based upon the price for which the senior deferrable notes are remarketed.

                                       44


The  remarketing  of the senior  deferrable  notes was  scheduled for August 13,
2003. The holders of approximately 6.36 million PEPS Units opted to settle their
purchase  contract  obligations  by  remarketing  the  senior  deferrable  notes
(totaling $159 million),  while holders of approximately 0.54 million PEPS Units
elected to settle their purchase contract obligations with cash and retain their
senior deferrable notes (totaling $13.6 million) in lieu of participating in the
remarketing.  On August 13, Valero received  notice from the  remarketing  agent
that a failed  remarketing  of the  senior  deferrable  notes was deemed to have
occurred.  The $159 million of senior  deferrable notes surrendered to Valero to
satisfy the holders' purchase contract obligations will be retained by Valero in
full satisfaction of the holders'  obligations under the purchase  contracts and
will be canceled  on August 18,  2003.  The  remaining  $13.6  million of senior
deferrable notes will remain  outstanding for their remaining two-year term, and
the interest rate for these ntoes will be 6.797%.

Other Commercial Commitments
As of June 30, 2003, Valero's committed lines of credit included (in millions):

                                                 Borrowing

                                                  --------         ----------
  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,  its  debt-to-capitalization
ratio  (net of cash)  was  42.6%  as of June  30,  2003.  For  purposes  of this
computation,  20% of the $172.5 million of aggregate liquidation amount of trust
preferred securities issued as part of the PEPS Units was included as debt.

As of June 30, 2003, Valero had $150.0 million of letters of credit  outstanding
under its  uncommitted  short-term  bank credit  facilities,  $238.3  million of
letters of credit  outstanding  under its  committed  facilities  and Cdn.  $7.9
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  believes  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.

On April 11, 2003,  the  underwriters  of the common unit offering  discussed in
Note 3 elected to exercise a portion of their overallotment option by purchasing
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%.  Valero's  ownership  interest was
further  reduced  to 45.8% as a result  of the  issuance  by Valero  L.P.  of an
additional 1,236,250 common units on August 11, 2003.


                                       45


Pension Plan Funded Status
During  the  first six  months of 2003,  Valero  contributed  approximately  $21
million to its qualified  pension  plans.  Valero  expects to make an additional
contribution to these pension plans of $98 million prior to September 15, 2003.

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

Accounts Receivable Sales Facility
As of December 31, 2002, Valero had an accounts receivable sales facility with a
third-party  financial  institution  to sell  on a  revolving  basis  up to $250
million of eligible trade and credit card receivables,  which matures in October
2005. In June 2003, Valero amended its agreement to add two additional financial
institutions  to the program and to  increase  the size of its  facility by $350
million to $600 million. Under this program, wholly owned subsidiaries of Valero
sell an undivided  percentage  ownership  interest in the eligible  receivables,
without  recourse,  to the third-party  financial  institutions.  Valero remains
responsible  for servicing  the  transferred  receivables  and pays certain fees
related to its sale of receivables  under the program.  As of June 30, 2003, the
amount of eligible  receivables sold to the third-party  financial  institutions
was $600 million.

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.  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 in
April 2003 and the purchase of certain convenience stores for approximately $215
million in June 2003,  Valero believes that it is not reasonably  likely that it
will purchase  assets subject to the structured  lease  arrangements 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.  See Note 2 of Notes to
Consolidated Financial Statements for a discussion of FIN 46.

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 $40 million as of June 30, 2003. This lease
expires in 2010.

Valero's  structured  lease  arrangements  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 June 30, 2003, the maximum  residual value  guarantee under
Valero's structured lease arrangements was approximately $398 million.

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 June 30, 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 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

                                       47


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  that  Valero  intends to redeem in the
future. Under these contracts,  Valero sold $400 million of Canadian dollars and
bought  $253.4  million of U.S.  dollars.  As of June 30, 2003 and  December 31,
2002,  these  contracts  had a fair value of $(26.9)  million and $6.1  million,
respectively.  For the six months ended June 30, 2003, Valero recognized a $33.5
million  loss on these  contracts,  which was offset by a gain of $29.6  million
recognized  in income from the effect of the exchange  rate  fluctuation  on the
hedged asset.  As of June 30, 2003,  $202.5  million of these  contracts  remain
outstanding and mature as follows (in millions):

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-15(e) under the Securities Exchange Act of 1934) as of the end of the period
covered by 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 control over financial reporting.

     There have been no changes in  Valero's  internal  control  over  financial
reporting  (as defined in Rule  13a-15(f)  under the Exchange Act) that occurred
during  Valero's  last  fiscal  quarter  that  has  materially  affected,  or is
reasonably likely to materially affect, Valero's internal control over financial
reporting.


PART II - OTHER INFORMATION

Item 1.  Legal Proceedings

Michigan  Department of Environmental  Quality,  et al. v. Imlay City Gas & Oil,
Inc. and TPI Petroleum,  Inc., 30th State Judicial Circuit Court, Ingham County,
Michigan (filed June 28, 2002) (this matter was last reported in Valero's Annual
Report on Form 10-K for the year  ended  December  31,  2002).  This was a civil
action brought by the Attorney General of the State of Michigan and the Michigan
Department of Environmental  Quality (MDEQ) to enforce an  Administrative  Order
for  Response  Activity  issued by the MDEQ.  The  Administrative  Order  sought
specific  actions from  the defendants  to abate and remedy releases of alleged

                                       52

hazardous  substances  from a retail station in Tuscola  County,  Michigan.  The
named  defendants  were  the  present  and  prior  owners  of the  station.  TPI
Petroleum,  Inc.  (TPI) is a wholly  owned  subsidiary  of Valero.  TPI sold the
station in 1993 to Imlay City Gas & Oil, Inc.  (Imlay).  Imlay is not affiliated
with Valero. In June 2003, the court dismissed TPI from the lawsuit.

New Mexico Environment Department (Tucumcari terminal). Valero received a notice
of violation on June 16, 2003 from the New Mexico Environment  Department (NMED)
concerning an alleged violation of Title V of the Clean Air Act at Valero L.P.'s
refined  products  terminal in  Tucumcari,  New Mexico.  NMED  alleges  that the
terminal  operated as a Title V source from December 14, 1994 through  September
6, 1998, and that the terminal  failed to apply for a Title V permit during that
time  period.  The NOV  includes a maximum  penalty of $20 million  (based on an
aggregate 1,357 days of alleged  noncompliance),  but NMED has offered to settle
the matter for  $113,400.  Valero is assessing its defenses to NMED's claims and
is negotiating with NMED to resolve the matter. Because this matter relates to a
period prior to Valero L.P.'s ownership of the Tucumcari  terminal,  Valero will
remain responsible for any costs related to resolution of the matter.

Texas Commission on Environmental Quality (TCEQ) (Corpus Christi West Refinery).
Valero  received  a notice  of  enforcement  dated  July 7,  2003  from the TCEQ
effectively  consolidating  five prior notices of violation relating to Valero's
Corpus  Christi West  Refinery.  The notice  alleges  certain  unauthorized  air
emissions  and  record-keeping  violations  in 2000  and 2001  and  assesses  an
administrative  penalty  of  $103,625.  Valero is  negotiating  with the TCEQ to
settle this matter.

TCEQ (Texas City Refinery).  Valero received a notice of enforcement  dated July
18, 2003 from the TCEQ relating to a wastewater  treatment  facility operated by
Valero in connection with the operations of its Texas City Refinery.  The notice
alleges   noncompliance   with  certain  effluent   limitations  and  monitoring
requirements   in  2002  in   violation  of  the  Texas  Water  Code  and  Texas
Administrative Code and assesses an administrative  penalty of $146,850.  Valero
is assessing its defenses to the TCEQ's claims and expects to negotiate with the
TCEQ to resolve this matter.


Item 2.  Changes in Securities and Use of Proceeds

          (a) Title of class of registered securities: UDS Capital I 8.32% Trust
     Originated Preferred Securities. On June 30, 2003, Valero redeemed all $200
     million of the  outstanding  8.32% Trust  Originated  Preferred  Securities
     issued by UDS Capital I (a wholly owned  subsidiary  trust of Valero).  The
     redemption  was funded with part of the proceeds from Valero's  issuance on
     June 4, 2003 of $300  million  of 4.75%  notes due June 15,  2013 under its
     shelf registration statement.

     (liquidation  preference $25 per share)  (Convertible  Preferred  Stock). A
     registration statement was filed with the SEC on Form S-3 (Registration No.
     333-106949) with respect to these securities on July 11, 2003.  Valero will
     pay annual  dividends on each share of Convertible  Preferred  Stock in the
     amount  of $0.50  when,  as and if  declared  by its  board  of  directors.
     Dividends will be paid  quarterly,  provided that dividends will not accrue
     or be payable with respect to a particular  calendar quarter if Valero does
     not declare a dividend on its common  stock during that  calendar  quarter.
     The  Convertible  Preferred Stock will rank with respect to dividend rights
     and rights upon Valero's liquidation, winding-up or dissolution as follows:
     (i) senior to all  common  stock and to all other  capital  stock of Valero
     issued in the future that ranks junior to the Convertible  Preferred Stock;
     (ii) on a parity with any of Valero's  capital  stock  issued in the future
     the terms of which expressly provide that it will rank on a parity with the
     Convertible  Preferred  Stock;  and (iii) junior to all of Valero's capital


                                       53
