                         Report of Independent Auditors

Allegheny Technologies Incorporated

We have audited the accompanying statements of net assets available for benefits
of The 401(k) Plan 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.

                          Notes to Financial Statements

                                December 31, 2002

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) Plan (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 provide retirement benefits to eligible employees
through company contributions and to encourage employee thrift by permitting
eligible employees to defer a part of their compensation and contribute such
deferral to the Plan. The Plan allows employees to contribute a portion of
eligible wages each pay period through payroll deductions subject to Internal
Revenue Code limitations. Qualifying employee contributions are partially
matched by Allegheny Technologies Incorporated (ATI, the Plan Sponsor), up to
the lesser of a maximum of $1,000 annually for each participant, or 50% of
participants' deferrals up to a maximum of 3.5% of total eligible wages (except
for Allvac and Wah Chang). For the Company's Allvac and Wah Chang operations,
effective January 1, 2002, the $1,000 maximum limit on matching contributions
was removed.

In addition, annual flat dollar contributions will be paid into the Plan at the
end of each year provided the following criteria are met: the employee must have
contributed a minimum of 2% of their total earnings for the year into the Plan;
the employee must have completed a minimum

2. DESCRIPTION OF THE PLAN (CONTINUED)

of 1,000 hours during the calendar year; and the employee must be an active, non
union employee as of December 31st of that year. The exception to this rule is
that employees who retire during the calendar year will remain eligible for this
contribution, so long as they meet the 1,000 hour rule. Such retirees will
receive a pro rated contribution, based on the number of months they worked in
the year. However, an employee who terminates (not retires) prior to December
31st will not be eligible for this flat dollar contribution, regardless of the
number of hours worked.

The flat dollar contribution amounts are based on the employee's years of
service, as follows:



         Years             Amount of Contribution
         -----             ----------------------
                        
         0 - 4             $100
         5 - 9             $500
         10 - 14           $600
         15 - 19           $700
         20 - 24           $800
         25 - 29           $1,000
         30 - 34           $1,500
         35 or more        $2,000


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.

2. DESCRIPTION OF THE PLAN (CONTINUED)

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 $1,000
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

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

3. INVESTMENTS (CONTINUED)

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 year 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.

                    Notes to Financial Statements (continued)


3. INVESTMENTS (CONTINUED)

Interest, realized and unrealized gains and losses, and management fees from the
master trusts are included in the net loss from interest in Allegheny
Technologies Incorporated Savings Plan Trust on the statement of changes in net
assets available for benefits.

4. INCOME TAX STATUS

The Plan has received a determination letter from the Internal Revenue Service
dated December 2, 1997, 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 administrator
believes the Plan is being operated in compliance with the applicable
requirements of the Code and, therefore, believes that the Plan, as amended, is
qualified and the related trust is tax-exempt.

5. PARTIES-IN-INTEREST

Dreyfus Corporation is the manager of the Dreyfus Mutual Funds that are offered
as investment options under this Plan. Dreyfus Service Corporation is the funds'
distributor. Dreyfus Corporation and Dreyfus Service Corporation are both wholly
owned subsidiaries of Mellon Financial Corporation. Mellon Financial Corporation
also owns Mellon Bank, N.A., the Trustee for this Plan. Therefore, transactions
with these entities qualify as party-in-interest.

6. PLAN TERMINATION

Although it has not expressed any intent to do so, the Plan Sponsor has the
right under the Plan to discontinue its contributions at any time and to
terminate the Plan subject to the provisions of ERISA.
