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


7


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
----
Balance as of June 30, 2003.................. $ 32.8

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

FASB Interpretation No. 45
In November 2002, the FASB issued Interpretation No. 45, "Guarantor's Accounting
and Disclosure Requirements for Guarantees, Including Indirect Guarantees of
Indebtedness of Others" (FIN 45). FIN 45 addresses the disclosures to be made by
a guarantor in its interim and annual financial statements about its obligations
under guarantees. These disclosure requirements were effective for financial
statements of interim and annual periods ending after December 15, 2002 and are
included in Note 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

8


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


10

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

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

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.

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
o various adjustments to property, plant and equipment, goodwill and
certain current and noncurrent assets and liabilities resulting from
adjustments to the purchase price allocations related to Valero's

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.

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

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


19

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.

VALERO ENERGY CORPORATION AND SUBSIDIARIES

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

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.

24



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
materially, from any estimates, predictions, projections, assumptions or other
future performance suggested in this report. These forward-looking statements
can generally be identified by the words "anticipate," "believe," "expect,"
"plan," "intend," "estimate," "project," "budget," "forecast," "will," "could,"
"should," "may" and similar expressions. These forward-looking statements
include, among other things, statements regarding:

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

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

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



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;
o changes in the credit ratings assigned to Valero's debt securities and
trade credit;
o changes in the value of the Canadian dollar relative to the U.S.
dollar; and
o overall economic conditions.

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

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

The following notes relate to references on pages 29 through 32.
(a) On March 18, 2003, Valero's ownership interest in Valero L.P. decreased
from 73.6% to 49.5%. As a result of this decrease in ownership of Valero
L.P. combined with certain other partnership governance changes, Valero
ceased consolidating Valero L.P. as of that date and began using the equity
method to account for its investment in the partnership.
(b) EBITDA is a non-GAAP measure, the reconciliation of which is included in
"Results of Operations - Corporate Expenses and Other."
(c) The ratio of EBITDA to interest incurred is a non-GAAP measure and is
calculated by dividing EBITDA by interest and debt expense incurred as
reflected in the consolidated statements of income.
(d) Throughput margin per barrel represents operating revenues less cost of
sales divided by throughput volumes.
(e) The Gulf Coast refining region includes the Corpus Christi East, Corpus
Christi West, Texas City, Houston, Three Rivers and Krotz Springs
Refineries; the Mid-Continent refining region includes the McKee, Ardmore
and Denver Refineries; the Northeast refining region includes the Quebec
and Paulsboro Refineries; and the West Coast refining region includes the
Benicia and Wilmington Refineries.
(f) The average market reference prices and differentials, with the exception
of the propylene and lube oil differentials, are based on posted prices
from Platt's Oilgram. The propylene differential is based on posted
propylene prices in Chemical Market Associates, Inc. and the lube oil
differential is based on Exxon Mobil Corporation postings provided by
Independent Commodity Information Services-London Oil Reports. The average
market prices and differentials are presented to provide users of the
consolidated financial statements with economic indicators that
significantly affect Valero's operations and profitability.

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):

Condition and Results of Operations - Results of Operations - 2002 Compared to

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

Under Valero's revolving bank credit facilities, 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.


46


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):

Year Ending Notional
December 31, Amount
------------ ------
2004....... $ 37.9

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.

(b) Issuance of Valero Preferred Stock. On July 1, 2003, Valero issued
10 million shares of its 2% mandatory convertible preferred stock
(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


stock the terms of which expressly provide that such capital stock will
rank senior to the Convertible Preferred Stock.
