2 INDEPENDENT AUDITORS' REPORT The Benefits Committee Quanex Corporation Houston, Texas Re: Quanex Corporation Hourly Bargaining Unit Employees Savings Plan We have audited the accompanying statements of net assets available for benefits of the Quanex Corporation Hourly Bargaining Unit Employees Savings Plan (the "Plan") as of December 31, 1998 and 1997 and the related statements of changes in net assets available for benefits for the years then ended. 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 generally accepted auditing standards. 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, such financial statements present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 1998 and 1997 and the changes in net assets available for benefits for the years then ended in conformity with generally accepted accounting principles. Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The accompanying supplemental schedules of (1) investments as of December 31, 1998 and (2) 5% reportable transactions for the year ended December 31, 1998 are presented for the purpose of additional analysis and are not a required part of the basic financial statements but are 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. The supplemental information by fund in the statements on net assets available for benefits is presented for the purpose of additional analysis rather than to present the net assets available for benefits of the individual funds. The supplemental schedules and the supplemental information by fund is the responsibility of the Plan's management. Such supplemental schedules and supplemental information by fund have been subjected to the auditing procedures applied in our audit of the basic financial statements and, in our opinion, are fairly stated in all material respects when considered in relation to the basic financial statements taken as a whole. /s/ DELOITTE & TOUCHE LLP - ------------------------- DELOITTE & TOUCHE LLP June 1, 1999

5 QUANEX CORPORATION HOURLY BARGAINING UNIT EMPLOYEES SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS YEARS ENDED DECEMBER 31, 1998 AND 1997 A. DESCRIPTION OF THE PLAN The following description of the Quanex Corporation Hourly Bargaining Unit Employees Savings Plan (the "Plan") is provided for general informational purposes only. Participants should refer to the Plan document for more complete information. (1) General. The Plan, originally named the Quanex Corporation Hourly Employees Savings Plan, became effective January 1, 1989 and is sponsored by Quanex Corporation (the "Company"). The Plan began receiving contributions in April 1989. The Plan is a defined contribution plan which is subject to the Employee Retirement Income Security Act of 1974 ("ERISA"). The Plan is a voluntary savings plan in which hourly employees of certain divisions of the Company are eligible to participate after completing three months of active service. The assets of the Plan are held in trust by Fidelity Management Trust Company ("Fidelity" or the "Trustee"). The Benefits Committee (the "Committee"), appointed by the Company's Board of Directors, serves as the Plan administrator. (2) Contributions. Participants may elect to contribute up to 15% of their before-tax or after-tax compensation as defined by the Plan agreement. The Plan was amended effective July 1, 1994 to include LaSalle Steel Company hourly employees (Note E). All plan provisions applied to the LaSalle Steel Company hourly employees with the addition of an employer matching contribution that did not exceed 5% of the member's considered compensation. (3) Participant Accounts. Each participant's account is credited with the participant's contribution and an allocation of investment income, which is based on individual participant account balances as of the end of the period in which the income is earned. (4) Investment Options. Participants may direct allocation of their contributions to the following funds: Fidelity Puritan Fund - invests in domestic and foreign common stocks, preferred stocks and bonds. Fidelity Magellan Fund - invests in equity and debt securities of foreign and domestic companies. Fidelity Contrafund - invests in equities of foreign and domestic companies. Fidelity Growth and Income Fund - invests in equity and debt securities of foreign and domestic companies. Fidelity Retirement Growth Fund - invests in common stocks and other securities. Fidelity Overseas Fund - invests in foreign equity and debt securities. Fidelity Balanced Fund - invests in common and preferred stocks and bonds. Fidelity Blue Chip Fund - invests in domestic and foreign common stocks. Fidelity Low-Priced Stock Fund - invests in domestic and foreign stocks.

6 Fidelity Government Money Market Fund - composed of short-term U.S. government obligations. Templeton Foreign Fund - invests in foreign securities. Neuberger & Berman Partner Trust Fund - invests in common stocks. Quanex Corporation Common Stock - invests exclusively in the common stock of Quanex Corporation. Common/Commingled Trust - invests in investment contracts issued by insurance companies, banks and other financial institutions. (5) Vesting. Participants are immediately vested in their contributions and the related earnings. Vesting in the employer's matching contributions for Lasalle Steel Company employees is 0% for less than one year of service graduating to 100% for five or more years. Upon death, retirement or total and permanent disability, the participant or beneficiary becomes immediately vested in the employer's contribution. In the event of termination, nonvested portions of employer's contributions are immediately forfeited by participants and utilized to reduce future employer matching contributions. (6) Payment of Benefits. Upon termination of service, the participant may elect to receive a lump sum distribution equal to the total amount of vested benefits in his or her account. As of December 31, 1998 and 1997, net assets available for benefits included benefits of $34,543 and $7,794, respectively, due to participants who had withdrawn from participation in the Plan. B. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (1) Accounting Basis. The financial statements of the Plan are prepared on the accrual basis of accounting in accordance with generally accepted accounting principles. (2) Investment Valuation. The Plan recognizes net appreciation or depreciation in the fair value of its investments. Investments are reflected at fair value in the financial statements. Fair value of mutual fund assets is determined using a quoted net asset value. Fair value for Quanex Corporation common stock, which is listed on the New York Stock Exchange, is determined using the last recorded sales price. The fair value of the common/commingled trust is at face value. (3) Use of Estimates. The preparation of financial statements in conformity with generally accepted accounting principles requires the use of estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of changes in the net assets available for benefits during the reporting period. The Plan's financial statements include amounts that are based on management's best estimates and judgments. Actual results could differ from these estimates. (4) Administrative Expenses. The Company pays all administrative expenses. (5) Payment of Benefits. Benefit payments are recorded when paid. C. PLAN TERMINATION Although it has not expressed any intention to do so, the Company has the right under the Plan to terminate the Plan at any time subject to the provisions set forth in ERISA. In the event of Plan termination, the assets held by the Trustee under the Plan will be valued and fully vested, and each participant will be entitled to distributions respecting his or her account.

7 D. FEDERAL INCOME TAX STATUS The Plan is subject to specific rules and regulations related to employee benefit plans under the Department of Labor and the Internal Revenue Service (the "IRS"). The Plan has received a favorable letter of tax determination dated April 25, 1997. As such, the Plan is a qualified trust under Sections 401(a) and 401(k) of the Internal Revenue Code (the "Code") and, as a result, is exempt from federal income tax under Section 501(a) of the Code. The Company believes the Plan is currently designed and being operated in compliance with the applicable requirements of the Code. The Company believes the Plan was qualified and the related trust was tax-exempt as of the financial statement dates. E. TRANSFER OF ASSETS Effective April 18, 1997, Quanex Corporation sold its LaSalle Steel Company subsidiary ("LaSalle") to Niagara Corporation. On December 1, 1997, assets of the Plan in the amount of $2,135,383 were transferred to the trustee of the LaSalle Steel Company Hourly Bargaining Unit Employees Savings Plan.
