These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2002 and 2001, and the changes in its net assets available for benefits for the years then ended, in conformity with accounting principles generally accepted in the United States. Our audits were performed for the purpose of forming an opinion on the financial statements taken as a whole. The accompanying supplemental schedule of assets (held at end of year) as of December 31, 2002 is presented for the purpose of additional analysis and is not a required part of the financial statements but is supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. This supplemental schedule is the responsibility of the Plan's management. The supplemental schedule has been subjected to the auditing procedures applied in our audit of the financial statements and, in our opinion, is fairly stated in all material respects in relation to the financial statements taken as a whole. /s/ ERNST & YOUNG LLP San Antonio, Texas June 24, 2003 3 VALERO SAVINGS PLAN STATEMENTS OF NET ASSETS AVAILABLE FOR BENEFITS December 31, ------------ 2002 2001 ---- ---- Assets: Investments: Common stock................................... $ 9,726,656 $ 72,759,294 Common/collective trusts....................... 10,338,552 38,472,131 Mutual funds................................... 8,931,594 142,540,740 Participant loans.............................. 1,930,471 7,071,335 Self-directed investments...................... 7,944 54,264 ---------- ----------- Total investments............................ 30,935,217 260,897,764 ---------- ----------- Receivables: Employer contributions......................... 3,902,528 908,205 Employee contributions......................... 80,417 2,462,133 Interest....................................... 289 - Due from brokers for securities sold........... 4,692 - ---------- ----------- Total receivables............................ 3,987,926 3,370,338 Cash............................................ 3,474 - ---------- ----------- Net assets available for benefits............... $ 34,926,617 $ 264,268,102 ========== =========== See Notes to Financial Statements. 4 VALERO SAVINGS PLAN STATEMENTS OF CHANGES IN NET ASSETS AVAILABLE FOR BENEFITS Years Ended December 31, ----------------------- 2002 2001 ---- ---- Additions to net assets: Investment income: Interest income................................................. $ 1,227,230 $ 2,651,173 Dividend income................................................. 1,330,903 5,391,527 ----------- ----------- 2,558,133 8,042,700 ----------- ----------- Contributions: Employee........................................................ 7,255,556 16,151,623 Employer........................................................ 7,553,105 6,623,279 ----------- ----------- 14,808,661 22,774,902 ----------- ----------- Asset transfers in from other plans: Valley Shamrock, Inc.

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 independent refining and marketing company with approximately 20,000 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 refined products through an extensive bulk and rack marketing network and a network of approximately 4,100 retail outlets in the United States and eastern Canada under various brand names including Diamond Shamrock(R), Shamrock(R), Ultramar(R), Valero(R), Beacon(R), Total(R) and Exxon(R). Valero's common stock trades on the New York Stock Exchange under the symbol "VLO". The following description of the Valero Savings Plan (the Plan) provides only general information. Participants should refer to the Plan document for a complete description of the Plan's provisions. General The Plan is a defined contribution plan that previously covered all eligible employees of Ultramar Diamond Shamrock Corporation (UDS), which was acquired by Valero on December 31, 2001. The Plan was previously referred to as the UDS 401(k) Retirement Savings Plan (renamed effective April 1, 2002). The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). Valero is the Plan sponsor. An administrative committee, consisting of persons selected by Valero, administers the Plan. The members of the Administrative Committee serve without compensation for services in that capacity. Vanguard Fiduciary Trust Company was the trustee and record keeper of the Plan until June 30, 2002. Effective July 1, 2002, Merrill Lynch Trust Company, FSB became the trustee and has custody of the securities and investments of the Plan. Merrill Lynch, Pierce, Fenner & Smith Incorporated is the record keeper of the Plan. Plan Merger and Acquisitions Asset transfers in from other plans and asset transfers out to other plans include amounts related to the following: o Effective August 1, 2001, the Valley Shamrock, Inc. Employee's 401(k) Plan was merged into the Plan. Valley Shamrock, Inc. was previously acquired by UDS. o During 2001, participant account balances remaining in the UDS Employee Stock Ownership Plan 1 and 2 were transferred to the Plan. o Effective May 1, 2002, Valero merged the account balances related to UDS non-store employees (other than union personnel and HSB employees (defined below)), and effective August 1, 2002 merged the account balances related to certain union employees, into the Valero Energy Corporation Thrift Plan, representing a total transfer of $180,881,797. o Effective May 16, 2002, Valero sold certain assets and facilities related to its Golden Eagle Refinery to Tesoro Refining and Marketing Company (Tesoro), as a result of which certain employees of Valero (Held Separate Business Employees or HSB employees) became employees 6 VALERO SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS - (Continued) of Tesoro. HSB employees were treated as having incurred a termination of employment and became eligible for distributions of their account balances. Eligible HSB employees could elect to make direct rollover transfers from the Plan to a defined contribution plan maintained by Tesoro. Account balances of $8,271,147 for HSB employees who did not make direct rollover transfers were merged into the Valero Energy Corporation Thrift Plan. o Prior to September 1, 2002, Valero maintained the Valero Retail Plan for the benefit of certain Valero store employees. Effective September 1, 2002, the Valero Retail Plan was merged into the Plan. Any employees previously eligible to participate in the Valero Retail Plan became eligible to participate in the Plan. Participation Participation in the Plan is voluntary and is open to Valero retail employees who become eligible to participate. Prior to April 1, 2002, eligible employees included all former UDS 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, for non-store employees other than certain union personnel and HSB employees, effective May 16, 2002 for HSB employees, and effective July 1, 2002 for certain union employees, such former UDS non-store employees were no longer eligible to participate in the Plan but became eligible to participate in the Valero Energy Corporation Thrift Plan. Employees are eligible to participate in Valero's employer matching contributions after completion of one year of continuous service. Contributions Participants could contribute from 1% to 15% of their compensation, as defined in the Plan, through July 31, 2002. Effective August 1, 2002, participants can contribute up to 30% of their compensation. In addition, any employee may make rollover contributions. For the years ended December 31, 2002 and 2001, rollover contributions totaled $467,131 and $1,314,842, respectively, and are included in employee contributions in the statements of changes in net assets available for benefits. Valero contributes $0.60 for every $1.00 of the participant's contribution up to 6% of compensation. For each Plan Year beginning with the first Plan Year after December 31, 2001, Valero may, at the discretion of the Valero Energy Corporation Board of Directors or such other party as designated by such Board, make profit sharing contributions to the Plan to be allocated to the accounts of the "Eligible Members" as described in the plan document. For the year ended December 31, 2002, the Administrative Committee approved a $3,867,055 profit sharing contribution, which was funded in February of 2003. The Internal Revenue Code (the Code) establishes an annual limitation on the amount of individual pre-tax salary deferral contributions. This limit was $11,000 and $10,500 for the years ended December 31, 2002 and 2001, respectively. Effective September 1, 2002, participants who are eligible to make pre-tax contributions and who have attained age 50 before the end of the year are eligible to make an additional catch-up pre-tax contribution of up to $1,000. 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 and he resumes 7 VALERO SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS - (Continued) employment as an employee, any portion of the participant's account forfeited shall be restored if the participant repays to the Plan the full amount of his distribution within five years after re-employment. If the participant incurs five consecutive one-year breaks in service or fails to repay the distribution received from the vested portion of his account, the participant will permanently forfeit the nonvested portion of his account. Forfeited amounts are used to reduce future employer contributions or defray Plan administrative expenses. During the years ended December 31, 2002 and 2001, employer contributions were reduced by $10,193 and $159,066, respectively, from forfeited nonvested accounts. As of December 31, 2002, $26 in unused forfeitures is available for future use under the Plan. Participant Accounts Employer contributions are credited to an employer account for each participant and employee contributions are credited to an employee account maintained under the Plan for each participant. The employer and employee accounts for each participant are adjusted to reflect all contributions, withdrawals, income, expenses, gains and losses attributable to these accounts. Vesting Participants are vested 100% in their employee account at all times. Effective January 1, 2002, participants become 20% vested in their employer account for each year of service with 100% vesting after five years of service. Certain participants are subject to accelerated vesting as a result of special Plan provisions associated with past mergers. Participants vest in 100% of profit sharing contributions if and when years of vesting service are five years or more. 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, and termination or partial termination of the Plan, as defined in the Plan. 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 Energy Corporation Common Stock Fund, mutual funds, and common/collective trusts investments. Employer contributions are invested in Valero common stock. Effective January 1, 2002, participants may transfer 100% of Valero's employer contributions to any other investment option offered. Withdrawals and Distributions A participant's vested account balance will be distributed after the later of reaching normal retirement age (generally age 65) or termination from employment, unless the participant elects an earlier distribution of his vested account balance at the earlier of termination from employment or age 59 1/2. Distributions can be made in the form of a single cash lump sum payment or monthly installments not to exceed five years. The participant can also elect that those funds in the Valero Common Stock Fund be distributed in the form of Valero common stock as: o A single payment; or o For distributions elected through June 30, 2002, annual installments over a period not to exceed the greater of his life expectancy or ten years; or o For distributions effective on or after July 1, 2002, annual installments over a period not to exceed five years. If the participant's vested account balance is less than $5,000, the distribution cannot be deferred. 8 VALERO SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS - (Continued) In the event of hardship, participants may withdraw a portion of their vested account balance, subject to Administrative Committee approval. Effective August 1, 2002, hardship distributions may not be made more often than once in any six-month period. Upon completion of five years of participation in the Plan, a participant can elect to withdraw any amount credited to his after-tax contribution account, matching contributions account and profit sharing contributions account. Additionally, the participant is eligible to elect another withdrawal upon the completion of 36 months from the date of a previous withdrawal. Participant Loans Participants may borrow a minimum of $500 ($1,000 prior to August 1, 2002) 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 15 years for the purchase of a primary residence (10 years prior to August 1, 2002). 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 Administrative Committee. Principal and interest is repaid through payroll deductions. Effective August 1, 2002, a participant can have two loans outstanding at any time. Plan Expenses Valero pays the administrative expenses of the Plan and provides certain other services at no cost to the Plan. 2. Summary of Significant 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 of assets and changes therein reported in the financial statements, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates. Valuation of Investments Investments in mutual funds are valued at quoted market prices, which represent the net asset value of shares held by the Plan as of December 31. 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. Self-directed investments are valued at quoted market prices as of December 31. Participant loans are valued at cost which approximates fair value. Valero common stock is valued at its quoted market price as of December 31. 9 VALERO SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS - (Continued) 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. 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 investments, it is reasonably possible that changes in the value of investments 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. 3.

Party In Interest Transactions Certain Plan investments are shares of Valero common stock, and mutual funds and common/collective trusts 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 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 employer accounts. 7. Tax Status The Internal Revenue Service has determined and informed Valero by a letter dated September 30, 2002, that the Plan is designed in accordance with applicable sections of the Code. Although the Plan has been amended since receiving the determination letter, the Administrative Committee believes that the Plan is designed and is currently being operated in compliance with the applicable requirements of the Code. 8.
