Description of the Plan As used in this report, the term "Valero" may refer, depending upon the context, to Valero Energy Corporation, one or more of its consolidated subsidiaries, or all of them taken as a whole. Valero Energy Corporation is a publicly held refining and marketing company with over 22,000 employees. Valero owns and operates 12 refineries in the United States and Canada with a combined throughput capacity of approximately 1.9 million barrels per day. Valero markets its refined products through a network of approximately 4,600 retail outlets in the United States and eastern Canada under various brand names including Diamond Shamrock (R), Ultramar (R), Valero (R), Beacon (R) and Total (R). In addition, Valero owns a pipeline and terminal operation that complements its refining and marketing operations in the Texas Gulf Coast and Mid-Continent regions of the United States. Valero owns 73.6% of Valero L.P., a master limited partnership that owns and operates crude oil pipelines, refined product pipelines and refined product terminals in Texas, Oklahoma, New Mexico and Colorado. Valero's common stock trades on the New York Stock Exchange under the symbol "VLO" and Valero L.P.'s common units also trade on the New York Stock Exchange under the symbol "VLI." The following description of the Valero Energy Corporation Thrift Plan (the Thrift Plan) provides only general information. Participants should refer to the Thrift Plan document for a complete description of the Thrift Plan's provisions. General: The Thrift Plan is a qualified profit-sharing plan covering eligible employees of Valero in which participants' interests in Valero common stock are registered under the Securities Act of 1933. The Thrift Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). An administrative committee, consisting of persons selected by Valero, administers the Thrift Plan. The members of the administrative committee serve without compensation for services in that capacity. Merrill Lynch Trust Company of Texas is the trustee under the Thrift Plan and has custody of the securities and investments of the Thrift Plan through a trust (the Thrift Plan Trust). Merrill Lynch, Pierce, Fenner & Smith Incorporated is the record keeper for the Thrift Plan. Plan Mergers and Acquisitions: During the second quarter of 2000, Valero completed the acquisition of Exxon Mobil Corporation's Benicia, California refinery and Exxon-branded California retail assets (the Benicia Acquisition). Former ExxonMobil refinery and certain retail employees who became employees of Valero in connection with the Benicia Acquisition became eligible to participate in the Thrift Plan on May 16, 2000 and June 16, 2000, respectively, under the same service requirements as required for other Valero employees, with service including prior employment with ExxonMobil. These employees could elect to transfer their balances from the ExxonMobil employee savings plan into the Thrift Plan or maintain their balances in the ExxonMobil plan. Amounts transferred from the ExxonMobil plan into the Thrift Plan are included in asset transfers in from other plans in the statements of changes in net assets available for benefits. 7 VALERO ENERGY CORPORATION THRIFT PLAN NOTES TO FINANCIAL STATEMENTS - (Continued) Effective June 1, 2001, Valero completed the acquisition of El Paso Corporation's Corpus Christi, Texas refinery and related product logistics business. Former El Paso refinery employees who became employees of Valero in connection with the acquisition began participation in the Thrift Plan on June 1, 2001, while participation dates of former El Paso logistics employees varied depending on when they became employees of Valero. On the beginning date of their participation in the Thrift Plan, all former El Paso employees received credit for eligibility and vesting purposes for all prior service with El Paso. These employees became eligible to make contributions to the Thrift Plan after August 1, 2001 and could elect to transfer their balances from the El Paso employee savings plan or maintain their balances in the El Paso plan. Amounts transferred from the El Paso plan into the Thrift Plan are included in asset transfers in from other plans in the statement of changes in net assets available for benefits for the year ended December 31, 2001. Also effective June 1, 2001, Valero completed the acquisition of Huntway Refining Company, a leading supplier of asphalt in California. Former Huntway employees who became employees of Valero in connection with the acquisition began participation in the Thrift Plan and were eligible to make contributions on June 1, 2001, and received credit for eligibility and vesting purposes for all prior service with Huntway. Effective September 1, 2001, the Huntway 401(k) plan was merged into the Thrift Plan. The net assets of the Huntway 401(k) plan are included in asset transfers in from other plans in the statement of changes in net assets available for benefits for the year ended December 31, 2001. On December 31, 2001, Valero completed its acquisition of Ultramar Diamond Shamrock Corporation (UDS). Under the terms of the acquisition agreement, UDS shareholders (excluding certain UDS benefit plan participants) received, for each share of UDS common stock they held, at their election, cash, Valero common stock or a combination of cash and Valero common stock. Based on the exchange election results, UDS' shareholders electing Valero shares received, for each share of UDS common stock, 0.9265 shares of Valero common stock and $16.32 in cash. Shareholders electing cash and non-electing shareholders received $49.47 in cash for each share of UDS common stock. Based on the above, the total consideration paid by Valero to UDS shareholders included approximately $2.1 billion in cash and approximately 45.9 million shares of Valero common stock. Valero accounted for the UDS acquisition using the purchase method. See note 9, "Subsequent Events". Participation: Participation in the Thrift Plan is voluntary and is open to Valero employees who become eligible to participate upon the completion of 30 days of continuous service. However, retail store employees and former UDS employees are not eligible to participate in the Thrift Plan as they are eligible to participate in other plans sponsored by Valero. Employees are eligible to participate in Valero's employer matching contributions after completion of one year of continuous service. Continuous service begins the first day for which an employee is paid and terminates on the date of the employee's retirement, death or other termination from service. If an employee's employment is terminated and the employee is subsequently reemployed within 12 months, the period between the severance from service and the date of reemployment is generally included in continuous service. If the employee is not reemployed within 12 months, the employee is deemed to have incurred a break in service. Former participants who are reemployed after a break in service are generally eligible to become participants immediately following reemployment. 8 VALERO ENERGY CORPORATION THRIFT PLAN NOTES TO FINANCIAL STATEMENTS - (Continued) Contributions: Through December 31, 2001, participants could make basic contributions of not less than 2% or more than 8% of their annual total salary immediately upon commencement of participation. In addition, participants making a basic contribution of 8% could also make a supplemental contribution of up to 14% of their annual total salary. Annual total salary represents a participant's current base salary including commissions, overtime, job upgrade pay and shift differential pay, and is not reduced for pretax contributions for the purchase of benefits and to reimbursement accounts for medical and child care expenses under Valero's FlexPlan benefits program and pretax contributions under the Thrift Plan itself. Effective November 1, 2000, the Thrift Plan was amended to provide that bonuses, which previously had been included in annual total salary, are now not included in annual total salary unless the participant elects to do so. Participants may change their basic or supplemental contribution percentages at any time. In addition, any employee may make rollover contributions. Participants elect to make contributions to the Thrift Plan on a before-tax and/or after-tax basis. Federal income taxes on before-tax contributions are deferred until the time a distribution is made to the participant. The Internal Revenue Code (the Code) establishes an annual limitation on the amount of individual pre-tax salary deferral contributions. The limit was $10,500 for the years ended December 31, 2001 and 2000. Valero makes an employer contribution to the Thrift Plan equal to 75% of participants' basic contributions up to 8% of their annual base salary. If Valero's return on equity for the prior year is equal to or greater than 10%, then Valero's employer contribution shall equal 100% of the participant's basic contributions relating to the participant's annual base salary for the 12-month period beginning February 1 of the calendar year following the year in which the 10% return is achieved. Valero's return on equity for the year ended December 31, 2000 was greater than 10%; therefore, Valero's matching percentage was increased from 75% to 100% for the 12-month period beginning February 1, 2001. Forfeitures: Valero's employer contributions are reduced by any forfeited non-vested accounts of terminated participants and increased by the value of prior forfeited non-vested accounts for participants who are rehired within five years from date of termination. Valero's employer contributions are made in shares of Valero common stock. For the year ended December 31, 2001 and 2000, employer contributions were reduced by $130,552 and $33,672, respectively, from forfeited non-vested accounts. As of December 31, 2001, forfeited non-vested accounts available to reduce future employer contributions were $63. Participant Accounts: Employer contributions are credited to an Employer Account and employee contributions are credited to an Employee Account maintained under the Thrift Plan for each participant. The Employer and Employee Accounts are adjusted to reflect all contributions, withdrawals, income, expenses, gains and losses attributable to these accounts. Employer contributions are allocated to each participant's Employer Account in the proportion that a participant's basic contribution attributable to their annual base salary bears to the total of comparable basic contributions for all participants. 9 VALERO ENERGY CORPORATION THRIFT PLAN NOTES TO FINANCIAL STATEMENTS - (Continued) Vesting: Participants are vested 100% in their Employee Account at all times. Participants vest in their Employer Account at the rate of 20% per year with 100% vesting after the fifth year of continuous service. The Thrift Plan provides that if an employee incurs a break in service prior to becoming vested in any part of their Employer Account, the employee's prior continuous service will not be disregarded for purposes of the Thrift Plan until the break in service equals or exceeds the greater of five years or the period of prior continuous service. Upon a participant's termination of employment for other than death, total and permanent disability or retirement, the non-vested portion of the participant's Employer Account is forfeited. In the event the participant is reemployed prior to incurring a break in service of five successive years, any amounts forfeited under this provision will be reinstated. Investment Options: Participants direct the investment of 100% of their employee contributions and may transfer existing account balances into any of the funds offered. The funds offered include the Valero Common Stock Fund, mutual funds, pooled separate accounts, a common/collective trust and other self-directed investments. Employer contributions are invested in Valero common stock. For contributions made after June 1, 2000 and through December 31, 2001, participants could transfer up to 50% of Valero's employer contribution to any other fund offered. The remaining 50% could only be invested in the Valero Common Stock Fund and was non-transferable until the participant reached early retirement age (age 55 and five years of credited service) or age 59 1/2. Effective January 1, 2002, employer contributions can be immediately diversified into other funds, including existing employer contributions. Withdrawals and Distributions: Participants may make the following types of withdrawals of all or part of their respective accounts: o one withdrawal during any 12-month period from a participant's after-tax Employee Account and rollover contribution account with no suspension of future contributions; o upon completion of five years of participation in the Thrift Plan, one withdrawal from the participant's after-tax Employee Account and Employer Account, with a similar withdrawal allowed 36 months after the date of a previous withdrawal under this provision, with no suspension of future contributions; o upon reaching age 59 1/2, one withdrawal during any 12-month period from a participant's Employee Account and Employer Account; o upon furnishing proof of financial necessity, one withdrawal during any 12-month period from the participant's Employee Account and the vested portion of the Employer Account, but, for withdrawals of before-tax amounts, not to exceed the aggregate amount of the participant's before-tax contributions. Upon a participant's death, total and permanent disability or retirement, the participant, or beneficiary of a deceased participant, is entitled to a distribution of the entire value of the participant's Employee Account and Employer Account regardless of whether or not the accounts are fully vested. Upon a participant's termination for any other reason, the participant is entitled to a distribution of only the value of their Employee Accounts and the vested portion of their Employer Account. Distributions resulting from any of these occurrences may be received in a single sum in whole shares of Valero common stock and cash, or entirely in cash. Alternatively, a participant or beneficiary may elect to receive this distribution in the form of equal monthly installments over a period not exceeding the participant's life expectancy or the joint life expectancy of the participant and their designated beneficiary. The amount of this distribution is dependent upon the participant's age at commencement of the distribution and certain other factors. In addition, when the value of a distribution to a participant exceeds $5,000, the distribution may be made prior to the participant attaining age 65 only with the participant's consent. 10 VALERO ENERGY CORPORATION THRIFT PLAN NOTES TO FINANCIAL STATEMENTS - (Continued) Terminated participants may elect to have the Thrift Plan trustee hold their accounts for distribution to them at a date not later than April 1 of the calendar year after which they attain age 70 1/2. In this event, terminated participants continue to share in the earnings and losses of the Thrift Plan until their accounts are distributed. Participant Loans: Participants may borrow, subject to certain limitations, amounts credited to their Employee Account and the vested portion of their Employer Account. The minimum loan amount is $500. The maximum loan amount a participant may have outstanding is restricted to the lesser of: (a) $50,000, reduced by the excess of (i) the highest outstanding balance of the participant's loans during a one-year period over (ii) the participant's then currently outstanding loan balance on the day any new loan is made, or (b) one-half of the current value of the participant's vested interest in their Thrift Plan account. The term of any loan may not exceed five years unless the loan is for the purchase of a participant's principal residence, in which case, the term of the loan may not exceed 15 years. The balance of the participant's Employee Account and vested portion of his Employer Account serve as security for the loan. Loans bear interest at a reasonable rate as established by the Administrative Committee, presently at prime plus 1%. Loan repayments of principal and interest are made through payroll deductions or as otherwise determined. Participants may have up to two loans outstanding under the Thrift Plan at any time. Plan Expenses: Administrative expenses of the Thrift Plan, including trustee fees and expenses and other costs, are paid by Valero, or at Valero's option, by the Thrift Plan Trust. During the years ended December 31, 2001 and 2000, Valero paid $57,044 and $0 of administrative expenses. 2. Summary of Significant Accounting Policies Basis of Accounting: The financial statements of the Thrift Plan are prepared on the accrual basis of accounting in accordance with United States generally accepted accounting principles. Use of Estimates: The preparation of financial statements in conformity with United States generally accepted accounting principles requires management to make estimates that affect the amounts reported in the financial statements of assets and changes therein, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates. 11 VALERO ENERGY CORPORATION THRIFT PLAN NOTES TO FINANCIAL STATEMENTS - (Continued) Valuation of Investments: The Thrift Plan's investments are stated at fair value except for the investment contract, which is valued at contract value. Quoted market prices are used to value investments. Shares of mutual funds are valued at the net asset value of shares held by the Thrift Plan as of the balance sheet date. The investments in common/collective trusts are stated at fair value as determined by the issuer of the fund based on the fair value of the underlying assets. Investments in the Stable Value Fund are comprised of an investment in an investment contract and a common/collective trust. Money market funds and employee loans are valued at cost, which approximates fair value. Income Recognition: Purchases and sales of investments are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date. The net appreciation (depreciation) in fair value of investments consists of net realized gains and losses and the net unrealized appreciation (depreciation) of investments. Withdrawals by Participants: Withdrawals by participants are recorded when paid. Risks and Uncertainties: The Thrift Plan's investments, in general, are exposed to various risks, such as interest rate, credit and overall market volatility risks. Due to the level of risk associated with certain investment securities, it is reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect participants' account balances and amounts reflected in the statements of net assets available for benefits. Reclassifications: Certain previously reported amounts have been reclassified to conform to the 2001 presentation. 12 VALERO ENERGY CORPORATION THRIFT PLAN NOTES TO FINANCIAL STATEMENTS - (Continued) 3.

Party in Interest Transactions Certain Thrift Plan investments are shares of Valero common stock, and collective trusts and mutual funds that are managed by Merrill Lynch. Transactions in these investments qualify as party in interest transactions. 6. Plan Termination Although it has not expressed any intent to do so, Valero has the right under the Thrift Plan to discontinue its contributions at any time and to terminate the Thrift Plan subject to the provisions of ERISA. In the event of any termination of the Thrift Plan or complete discontinuance of employer contributions, participants would become 100% vested in their Employer Account. 7. Tax Status The Internal Revenue Service has determined and informed Valero by a letter dated April 21, 2002, that the Thrift Plan is designed in accordance with applicable sections of the Code. Although the Thrift Plan has been amended since receiving the determination letter, the Thrift Plan administrator believes that the Thrift Plan is designed and is currently being operated in compliance with the applicable requirements of the Code. 14 8.

VALERO ENERGY CORPORATION THRIFT PLAN By /s/ John D. Gibbons ------------------------------------- John D. Gibbons Chairman, Administrative Committee and Executive Vice President and Chief Financial Officer, Valero Energy Corporation Date: June 28, 2002 18 EXHIBIT 23.1 CONSENT OF INDEPENDENT AUDITORS We consent to the incorporation by reference in the Registration Statement (Form S-8 No. 333-31727) pertaining to the Thrift Plan of Valero Energy Corporation of our report dated June 26, 2002, with respect to the financial statements and schedule of the Valero Energy Corporation Thrift Plan included in this Annual Report (Form 11-K) for the year ended December 31, 2001. /s/ ERNST & YOUNG LLP San Antonio, Texas June 26, 2002 19 EXHIBIT 23.2 NOTICE REGARDING CONSENT OF ARTHUR ANDERSEN LLP On June 12, 2002, the Valero Energy Corporation Thrift Plan dismissed Arthur Andersen LLP as its independent auditors and appointed Ernst & Young LLP to replace Arthur Andersen LLP as the independent auditor of the Thrift Plan. Prior to the date of this Form 11-K (which is incorporated by reference into Valero Energy Corporation's filing on Form S-8 No. 333-31727), the Arthur Andersen partner responsible for the audit of the most recent audited financial statements of the Valero Energy Corporation Thrift Plan as of December 31, 2000 and for the year then ended resigned from Arthur Andersen. As a result, after reasonable efforts, the Plan has been unable to obtain Arthur Andersen's written consent to the incorporation by reference into Valero Energy Corporation's filing on Form S-8 No. 333-31727 of its audit report with respect to the Plan's financial statements as of December 31, 2000 and for the year then ended. Under these circumstances, Rule 437a under the Securities Act permits the Plan to file this Form 11-K without a written consent from Arthur Andersen LLP. However, as a result, Arthur Andersen LLP will not have any liability under Section 11(a) of the Securities Act for any untrue statements of a material fact contained in the financial statements audited by Arthur Andersen LLP or any omissions of a material fact required to be stated therein. Accordingly, you would be unable to assert a claim against Arthur Andersen LLP under Section 11(a) of the Securities Act because it has not consented to the incorporation by reference of its previously issued report into Valero Energy Corporation's filing on Form S-8 No. 333-31727. 20
