Report of Independent Auditors

Allegheny Technologies Incorporated

We have audited the accompanying statements of net assets available for benefits of the 401(k) Savings Account Plan for Employees of the Washington Plate Plant as of December 31, 2002 and 2001, 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 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 at 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 purposes 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. The supplemental schedule is the responsibility of the Plan's management. The supplemental schedule has been subjected to the auditing procedures applied in our audits 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.

401(k) Savings Account Plan for Employees of the Washington Plate Plant

Notes to Financial Statements

1. SIGNIFICANT ACCOUNTING POLICIES

Investments are valued as follows:

Bank and insurance contracts with varying contract rates and maturity dates are stated at contract value.

Although it is management's intention to hold the investment contracts in the Fixed Income Fund until maturity, certain investment contracts provide for adjustments to contract value for withdrawals made prior to maturity.

All other funds are stated at their net asset value, based on the quoted market prices of the securities held in such funds on applicable exchanges.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

2. DESCRIPTION OF THE PLAN

The 401(k) Savings Account Plan for Employees of the Washington Plate Plant (the Plan) is a defined contribution plan and is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA).

The purpose of the Plan is to encourage thrift and to assist union employees of the Allegheny Ludlum Corporation (the Company) of the Washington Plate facility in accumulating a fund to supplement retirement income by allowing eligible employees to make tax-deferred contributions to the Plan. Allegheny Ludlum Corporation is a wholly owned subsidiary of Allegheny Technologies Incorporated (ATI, the Plan Sponsor). The Plan allows employees to contribute a portion of eligible wages each pay period through payroll deductions subject to Internal Revenue Code limitations. In addition, the employee's annual pretax profit sharing award and pretax Longevity Incentive Payment Plan award may be contributed at the employee's discretion. The Company contributes $0.50 for each hour worked per eligible union employee. Unless otherwise specified by the participant, all contributions are made to the Fixed Income Fund. Such contributions are made only from current income or accumulated earnings of the Plan Sponsor.

2. DESCRIPTION OF THE PLAN (CONTINUED)

Separate accounts are maintained by the Plan Sponsor for each participating employee. Trustee fees and asset management fees charged by the Plan's trustee, Mellon Bank, N.A., for the administration of all funds are charged against net assets available for benefits of the respective fund. Certain other expenses of administering the Plan are paid by the Plan Sponsor.

Participants may make "in-service" and hardship withdrawals as outlined in the plan document.

Active employees can borrow up to 50% of their vested account balances minus any outstanding loans. The loan amounts are further limited to a minimum of $500 and a maximum of $50,000, and an employee can obtain no more than three loans at one time. Interest rates are determined based on commercially accepted criteria, and payment schedules vary based on the type of the loan. General purpose loans are repaid over 6 to 60 months, and primary residence loans are repaid over periods up to 180 months. Payments are made by payroll deductions.

Effective November 29, 1999, Allegheny Teledyne Incorporated's name was changed to Allegheny Technologies Incorporated. Also, the Aerospace and Electronics and Consumer segments of Allegheny Teledyne were spun off into two new freestanding public companies--Teledyne Technologies Incorporated and Water Pik Technologies, Inc. Stockholders of Allegheny Teledyne became stockholders of Teledyne Technologies Incorporated and Water Pik Technologies, Inc., thus creating two new master trusts. Participants continued to hold interests in the two new companies until December 31, 2002, at which time these two holdings were terminated and the assets were transferred to one of the other plan investment options.

Further information about the Plan, including eligibility, vesting, contributions, and withdrawals, is contained in the plan documents, summary plan description and related contracts. These documents are available from the Plan Sponsor.

Certain of the Plan's investments are in the Allegheny Technologies Incorporated Savings Plan Trust, which has three subsidiary Master Trusts: the Allegheny Technologies Disciplined Stock Fund Master Trust, the Alliance Equity Master Trust and the Fixed Income Master Trust, which are institutional separate accounts valued on a unitized trust basis (collectively, the "Master Trust"). The Master Trust was established for the investment of assets of the Plan, and several other ATI sponsored retirement plans. Each participating retirement plan has an undivided interest in the Master Trust. At December 31, 2002 and 2001, the Plan's interest in the net assets of the Allegheny Technologies Disciplined Stock Fund Master Trust, the Alliance Equity Master Trust and the Fixed Income Master Trust were as follows:

                                                         2002         2001
                                                        ------------------

Fixed Income Master Trust                               0.47         0.26

Investment income and expenses are allocated to the Plan based upon its pro rata share in the net assets of the Master Trust.

401(k) Savings Account Plan for Employees of the Washington Plate Plant

The Fixed Income Fund (the Fund) invests in guaranteed investment contracts (GICs) and actively managed structured or synthetic investment contracts (SICs). The GICs are promises by a bank or insurance company to repay principal plus a fixed rate of return through contract maturity. SICs differ from GICs in that there are specific assets supporting the SICs, and these assets are owned by the Master Trust. The bank or insurance company issues a wrapper contract that allows participant-directed transactions to be made at contract value. The assets supporting the SICs are comprised of government agency bonds, corporate bonds, asset-backed securities (ABOs) and collateralized mortgage obligations (CMOs) with fair values of $88,750,762 and $55,854,607 at December 31, 2002 and 2001, respectively. The contract value minus the market value of the wrapper contracts at December 31, 2002 and 2001 is $(2,667,261) and $(1,397,030), respectively.

Interest crediting rates on the GICs in the Fund are determined at the time of purchase. Interest crediting rates on the SICs are either: (1) set at the time of purchase for a fixed term and crediting rate; (2) set at the time of purchase for a fixed term and variable crediting rate or (3) set at the time of purchase and reset monthly within a "constant duration." A constant duration contract may specify a duration of 2.5 years and the crediting rate is adjusted monthly based upon quarterly rebalancing of eligible 2.5 year duration investment instruments at the time of each resetting; in effect the contract never matures. At December 31, 2002 and 2001, the interest crediting rates for GICs and Fixed Maturity SICs ranged from 3.27% to 8.05% and 3.49% to 8.05%, respectively.

For the years ended December 31, 2002 and 2001, the average annual yield for the investment contracts in the Fund was 5.74% and 6.25%, respectively. Fair value of the GICs was estimated by discounting the weighted average of the Fund's cash flows at the then-current interest crediting rate for a comparable maturity investment contract. Fair value for the SICs was estimated based on the fair value of each contract's supporting assets at December 31, 2002 and 2001.

4. INCOME TAX STATUS

The Plan has received a determination letter from the Internal Revenue Service dated March 3, 1998, stating that the Plan is qualified under Section 401(a) of the Internal Revenue Code (the Code) and, therefore, the related trust is exempt from taxation. Subsequent to this issuance of the determination letter, the Plan was amended. Once qualified, the Plan is required to operate in conformity with the Code to maintain its qualification. The plan sponsor has indicated that it will take the necessary steps, if any, to maintain the Plan's qualified status.
