Description of the Plan As used in this report, the term "UDS" may refer, depending upon the context, to Ultramar Diamond Shamrock Corporation, one or more of its consolidated subsidiaries, or all of them taken as a whole. Prior to its acquisition by Valero Energy Corporation (Valero) on December 31, 2001, via the merger of UDS with and into Valero, UDS was an independent refiner and retailer of refined products and convenience store merchandise in the central, southwest and northeast regions of the United States and eastern Canada. UDS owned and operated seven refineries located in Texas (2), California (2), Oklahoma, Colorado and Quebec, Canada, and marketed its products through approximately 4,500 company-operated and dealer-operated convenience stores and 86 unattended cardlock stations. In the northeast region of the United States and in eastern Canada, UDS sold, on a retail basis, home heating oil to approximately 250,000 households. Effective April 1, 2002, the UDS 401(k) Retirement Savings Plan was renamed the Valero Savings Plan. The following description of the Valero Savings Plan (the Plan) provides only general information. Participants should refer to the Plan agreement for a more complete description of the Plan's provisions. General: The Plan is a defined contribution plan that previously covered all eligible employees of UDS. Eligible employees included all non-union employees and certain union employees who had completed one year of service and who were at least 18 years old. Effective April 1, 2002, non-store employees of UDS are no longer eligible to participate in the Plan but are eligible to participate in the Valero Energy Corporation Thrift Plan. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). Prior to its acquisition by Valero, UDS was the sponsor of the Plan. The Employee Benefits Committee (the Administrator), which consisted of at least three members appointed by the Chief Executive Officer of UDS, administered the Plan. Effective December 31, 2001, Valero became the Plan sponsor and Valero's Benefit Plans Administrative Committee became the Administrator of the Plan. Vanguard Fiduciary Trust Company is the trustee and record keeper of the Plan and has custody of the securities and investments of the Plan. Plan Merger and Acquisitions: On December 31, 2001, Valero completed its acquisition of UDS (UDS Acquisition). 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. 7 VALERO SAVINGS PLAN (formerly UDS 401(k) Retirement Savings Plan) NOTES TO FINANCIAL STATEMENTS - (Continued) Shares of UDS common stock held under the Plan, whether in the Ultramar Diamond Shamrock Corporation Common Stock Fund, the UDS ESOP1 Stock Fund or the UDS ESOP2 Stock Fund, were not subject to the proration of cash and Valero common stock as described above. Per the terms of the acquisition agreement, effective December 31, 2001, these shares were converted into Valero common stock based on the exchange ratio of 1.3826 shares of Valero common stock for each share of UDS common stock. On September 29, 2000, UDS acquired Valley Shamrock, Inc. Effective with this acquisition, employees of Valley Shamrock, Inc. became eligible to participate in the Plan. Effective August 1, 2001, the Valley Shamrock, Inc. Employee's 401(k) Plan was merged into the Plan. For the year ended December 31, 2001, asset transfers in from other plans in the statement of changes in net assets available for benefits includes $405,837 related to this plan merger. On August 31, 2000, UDS acquired the Golden Eagle Refinery from Tosco Corporation. Effective September 1, 2000, the employees at the Golden Eagle Refinery became eligible to participate in the Plan. In connection with this acquisition, UDS agreed to accept the one-time voluntary rollover of each Golden Eagle employee's account balance including outstanding loan balance from the Tosco Corporation Capital Accumulation Plan (the Tosco Plan). Effective October 31, 2000, the Golden Eagle employee accounts in the Tosco Plan were transferred to the Plan. These rollovers 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, 2000. Effective September 30, 1999, the Ultramar Diamond Shamrock Corporation Employee Stock Ownership Plan I and the Ultramar Diamond Shamrock Employee Stock Ownership Plan II (collectively known as the ESOP Plans) were merged with the Plan. Participant account balances from the respective ESOP Plans were transferred during 1999 from Key Trust Company, the trustee of the ESOP Plans, to Vanguard Fiduciary Trust Company's UDS ESOP1 Stock Fund and UDS ESOP2 Stock Fund. After the transfers were completed, 25% of the common shares were immediately eligible for diversification by the ESOP Plans' participants, with an additional 25% becoming eligible on January 1, 2000, 2001 and 2002. Contributions to the UDS ESOP1 Stock Fund or the UDS ESOP2 Stock Fund by the participants are not permitted. 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 is $101,527 and $17,127 of transfers in from the UDS ESOP1 Stock Fund and UDS ESOP2 Stock Fund, respectively. There were no transfers from the UDS ESOP1 Stock Fund or the UDS ESOP2 Stock Fund during the year ended December 31, 2000. Contributions: Participants can contribute from 1% to 15% of their compensation, as defined in the Plan. In addition, any employee may make rollover contributions. For the years ended December 31, 2001 and 2000, rollover contributions were $1,314,842 and $1,419,209, respectively, and are included in employee contributions in the statements of changes in net assets available for benefits. UDS contributes from $0.60 to $1.00 for every $1.00 of the participant's contribution up to 6% of compensation. UDS also makes a profit-sharing contribution based on 2% of compensation for certain participants from the Golden Eagle Refinery. 8 VALERO SAVINGS PLAN (formerly UDS 401(k) Retirement Savings Plan) NOTES TO FINANCIAL STATEMENTS - (Continued) UDS may make discretionary company contributions to the Plan for a plan year, subject to certain limitations. For the years ended December 31, 2001 and 2000, UDS did not make additional discretionary company contributions to the Plan. The Internal Revenue Code establishes an annual limitation on the amount of individual pre-tax salary deferral contributions. This limit was $10,500 for the years ended December 31, 2001 and 2000. Participant Accounts: Each participant's account is valued on a daily basis and is equal to the participant's and company contributions plus investment income less benefits paid to the participant. Vesting: Participants vest immediately in their contributions, rollover contributions and actual earnings thereon. Participants become 100% vested in company matching and discretionary contributions and related earnings after five years of service. Certain participants are subject to accelerated vesting as a result of special Plan provisions associated with past mergers. However, a participant will be vested in 100% of his account balance upon his death, disability, attainment of normal retirement age, as defined in the Plan, termination or partial termination of the Plan or a change in control, as defined in the Plan. Investment Options: During the years ended December 31, 2001 and 2000, participants were able to allocate their contributions and employer matching contributions and transfer existing account balances, except for certain amounts restricted under the UDS ESOP1 Stock Fund and the UDS ESOP2 Stock Fund, among mutual funds, a collective trust, other self-directed investments and the Ultramar Diamond Shamrock Corporation Common Stock Fund. Participant Loans: Participants may borrow a minimum of $1,000 up to a maximum equal to the lesser of $50,000 or 50% of their vested account balance. The participant may elect a repayment term of up to five years for general purpose loans or up to 10 years for the purchase of a primary residence. The loan is secured by a lien on the participant's vested account balance and bears interest at a reasonable rate as determined by the Administrator. Principal and interest is repaid through payroll deductions. A participant can have only one loan outstanding at any time and must wait three months after paying off a loan before initiating a new loan. Withdrawals and Distributions: Upon termination of service, a participant can choose a lump-sum distribution equal to the vested interest of his or her account or can defer receipt of such distribution, depending on the terminated participant's vested account balance. If the vested account balance is less than $5,000, the distribution can not be deferred. If the vested account balance is more than $5,000, the participant can consent to the distribution, or can defer to a later date, but not later than the normal retirement date. If the participant takes no action, the distribution is made at normal retirement date. Optional forms of payments are available to certain participants as described in the Plan agreement. 9 VALERO SAVINGS PLAN (formerly UDS 401(k) Retirement Savings Plan) NOTES TO FINANCIAL STATEMENTS - (Continued) In the event of hardship, participants can elect to withdraw a portion of their vested account balance, subject to income tax and penalties. Forfeitures: In the event a participant terminates before becoming 100% vested in the employer contributions, the nonvested employer contribution amounts held in the participant's account will be forfeited. If the terminated participant receives a distribution from the vested portion of his account, the nonvested amounts remaining in the participant's account are treated as a forfeiture. Forfeited amounts are used to reduce future employer contributions or defray Plan administrative costs. During the years ended December 31, 2001 and 2000, employer contributions were reduced by $159,066 and $230,659 from forfeited nonvested accounts, respectively. As of December 31, 2001, $18,209 in unused forfeitures is available for future use under the Plan. Plan Expenses: UDS pays the administrative expenses of the Plan and provides certain other services at no cost to the Plan. 2. Summary of Accounting Policies Basis of Accounting: The Plan's financial statements 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. Investment Valuation: Investments in mutual funds are valued at quoted market prices, which represent the net asset value of shares held by the Plan as of the balance sheet date. The investment in common/collective trust is stated at fair value as determined by the issuer of the fund based on the fair value of the underlying assets. Self-directed investments are valued at quoted market prices as of the balance sheet date. Participant loans are valued at cost which approximates fair value. UDS common stock is valued at its quoted market price as of the balance sheet date. 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. Net appreciation (depreciation) in fair value of investments consists of net realized gains and losses on the sale of investments and net unrealized appreciation (depreciation) of investments. 10 VALERO SAVINGS PLAN (formerly UDS 401(k) Retirement Savings Plan) NOTES TO FINANCIAL STATEMENTS - (Continued) Withdrawals by Participants: Withdrawals by participants are recorded when paid. Risks and Uncertainties: The Plan's investments, in general, are exposed to various risks, such as interest rate, credit and overall market volatility risk. Due to the level of risk associated with certain investment securities, it is reasonably possible that changes in the value of investment securities will occur in the near term and that such changes could materially affect participants' account balances and amounts presented in the statements of net assets available for benefits. Reclassifications: Certain previously reported amounts have been reclassified to conform to the 2001 presentation. 3.

Party In Interest Transactions Certain Plan investments are shares of mutual funds and a collective trust managed by an affiliate of the Trustee and shares of UDS common stock. Transactions in these investments qualify as party in interest transactions. 6. Plan Termination Although it has not expressed any intent to do so, UDS, and now Valero, has the right under the Plan to discontinue or reduce its contributions and to terminate the Plan at any time subject to the provisions of ERISA. In the event of plan termination, participants will become 100% vested in their accounts. 7. Tax Status The Internal Revenue Service has determined and informed UDS by a letter dated September 22, 1995, that the Plan and related trust are designed in accordance with applicable sections of the Internal Revenue Code. Although the Plan has been amended since receiving the determination letter, UDS, and now Valero, believe that the Plan is designed and is currently being operated in compliance with the applicable requirements of the Internal Revenue Code. 12 VALERO SAVINGS PLAN (formerly UDS 401(k) Retirement Savings Plan) NOTES TO FINANCIAL STATEMENTS - (Continued) 8.

Effective April 1, 2002, UDS non-store employees are no longer eligible to participate in the Plan but are eligible to participate in the Valero Energy Corporation Thrift Plan.

Gibbons Chairman, Administrative Committee and Executive Vice President and Chief Financial Officer, Valero Energy Corporation Date: June 28, 2002 17 Exhibit 23.1 CONSENT OF INDEPENDENT AUDITORS We consent to the incorporation by reference in the Registration Statements (Form S-8 Nos. 333-47322 and 333-81858) pertaining to the Savings Plan of Valero Energy Corporation (formerly UDS 401(k) Retirement Savings Plan) of our report dated June 26, 2002, with respect to the financial statements and schedules of the Valero Savings Plan (formerly UDS 401(k) Retirement Savings 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 18 EXHIBIT 23.2 NOTICE REGARDING CONSENT OF ARTHUR ANDERSEN LLP On June 12, 2002, the Valero Savings Plan (formerly UDS 401(k) Retirement Savings 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 Plan. Prior to the date of this Form 11-K (which is incorporated by reference into Valero Energy Corporation's filings on Form S-8 Nos. 333-47322 and 333-81858), the Arthur Andersen partner responsible for the audit of the most recent audited financial statements of the Valero Savings Plan (formerly UDS 401(k) Retirement Savings 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 filings on Form S-8 Nos. 333-47322 and 333-81858 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 filings on Form S-8 Nos. 333-47322 and 333-81858. 19
