     We are offering to exchange our outstanding notes described above for the
new, registered notes described above. The terms of the new notes are identical
in all material respects to the terms of the outstanding notes, except for
certain transfer restrictions, registration rights and additional interest
payment provisions relating to the outstanding notes. In this document we refer
to the outstanding notes as the "old notes" and to our new notes as the
"registered notes." We sometimes refer to the old notes and the registered notes
collectively as the "notes."

     The principal features of the exchange offer are as follows:

     - The only conditions to completing the exchange offer are that the
       exchange offer not violate applicable law or applicable interpretations
       of the staff of the Securities and Exchange Commission and that no
       injunction, order or decree has been issued which would prohibit, prevent
       or materially impair our ability to proceed with the exchange offer.

     - All old notes that are validly tendered and not validly withdrawn will be
       exchanged.

     - Tenders of old notes may be withdrawn at any time prior to the expiration
       of the exchange offer.

     - We will not receive any cash proceeds from the exchange offer.


     We are primarily a holding company and most of our operations are conducted
by our subsidiaries. The notes will be effectively subordinated to any of our
existing or future secured debt and to all liabilities of our subsidiaries,
including indebtedness of our subsidiaries. As of March 31, 2002, aggregate
indebtedness of our subsidiaries was approximately $213 million. As of that
date, we had total consolidated indebtedness, including the notes, of
approximately $525 million and the ability to borrow up to $325 million under
our revolving credit facility.

                              RECENT DEVELOPMENTS


     On March 22, 2002, we announced that our Wah Chang facility and the United
Steelworkers of America reached a new six-year labor agreement ending a
seven-month strike, which began on September 4, 2001. The new agreement covers
approximately 660 employees. The new agreement became effective on April 1, 2002
and expires on March 31, 2008. The anticipated increase in labor costs as a
result of the new agreement is less than one percent of our overall labor costs
and is not material. Our retirement benefit expense was $5.7 million in the
first quarter of 2002, and is expected to increase to approximately $6.8 million
per quarter for the remainder of 2002 as a result of the new agreement.



     On April 17, 2002, we announced the following financial results:

                   SUMMARY OF THE TERMS OF THE EXCHANGE OFFER

     On December 13, 2001, we issued in a private placement $300.0 million in
aggregate principal amount of our 8.375% notes due 2011 which we refer to in
this prospectus as the "old notes." We refer to this private placement in this
prospectus as the "original note offering." We entered into a registration
rights agreement with the initial purchasers of the old notes in which we agreed
to deliver to you this prospectus. You are entitled to exchange your old notes
in the exchange offer for registered notes with substantially identical terms,
except that the registered notes have been registered under the Securities Act
of 1933 and will not bear legends restricting their transfer. Unless you are a
broker-dealer or unable to participate in the exchange offer, we believe that
the notes to be issued in the exchange offer may be resold by you without
compliance with the registration and prospectus delivery requirements of the
Securities Act. You should read the discussions under the headings "The Exchange
Offer" and "Description of the Registered Notes" for further information
regarding the registered notes.

REGISTRATION RIGHTS
AGREEMENT.....................   You are entitled under the registration rights
                                 agreement to exchange your old notes for
                                 registered notes with substantially identical
                                 terms. The exchange offer is intended to
                                 satisfy these rights. After the exchange offer
                                 is complete, except as set forth in the next
                                 paragraph, you will no longer be entitled to
                                 any exchange or registration rights with
                                 respect to your old notes.

                                 The registration rights agreement requires us
                                 to file a registration statement for a
                                 continuous offering in accordance with Rule 415
                                 under the Securities Act of 1933 (the
                                 "Securities Act") for your benefit if, under
                                 applicable law, you would not receive freely
                                 tradeable registered notes in the exchange
                                 offer, you are ineligible to participate in the
                                 exchange offer, or in other specified
                                 circumstances and you notify us that you wish
                                 to have your old notes registered under the
                                 Securities Act. See "The Exchange
                                 Offer -- Procedures for Tendering."

THE EXCHANGE OFFER............   We are offering to exchange $1,000 principal
                                 amount of 8.375% notes due 2011, which have
                                 been registered under the Securities Act, for
                                 each $1,000 principal amount of our
                                 unregistered 8.375% notes due 2011 that were
                                 issued in the original note offering.

                                 In order to be exchanged, an old note must be
                                 properly tendered and accepted. All old notes
                                 that are validly tendered and not validly
                                 withdrawn will be exchanged.

                                 As of this date, there are $300.0 million
                                 aggregate principal amount of old notes
                                 outstanding.

                                 We will issue the registered notes promptly
                                 after the expiration of the exchange offer.

RESALES OF THE REGISTERED
NOTES.........................   We believe that registered notes to be issued
                                 in the exchange offer may be offered for
                                 resale, resold and otherwise transferred by you
                                 without compliance with the registration and
                                 prospectus delivery provisions of the
                                 Securities Act if you meet the following
                                 conditions:

                                 (1) the registered notes are acquired by you in
                                     the ordinary course of your business;

                                 (2) you are not engaging in and do not intend
                                     to engage in a distribution of the
                                     registered notes;

                                        5


                                 (3) you do not have an arrangement or
                                     understanding with any person to
                                     participate in the distribution of the
                                     registered notes; and

                                 (4) you are not an affiliate of ours, as that
                                     term is defined in Rule 405 under the
                                     Securities Act.


                                 Our belief is based on interpretations by the
                                 staff of the Securities and Exchange Commission
                                 (the "Commission"), as set forth in no-action
                                 letters issued to third parties unrelated to
                                 us. The staff has not considered this exchange
                                 offer in the context of a no-action letter, and
                                 we cannot assure you that the staff would make
                                 a similar determination with respect to this
                                 exchange offer.


                                 If you do not meet the above conditions, you
                                 may incur liability under the Securities Act if
                                 you transfer any registered note without
                                 delivering a prospectus meeting the
                                 requirements of the Securities Act. We do not
                                 assume or indemnify you against that liability.

                                 Each broker-dealer that is issued registered
                                 notes in the exchange offer for its own account
                                 in exchange for old notes which were acquired
                                 by that broker-dealer as a result of
                                 market-making activities or other trading
                                 activities must agree to deliver a prospectus
                                 meeting the requirements of the Securities Act
                                 in connection with any resales of the
                                 registered notes. A broker-dealer may use this
                                 prospectus for an offer to resell or to
                                 otherwise transfer these registered notes.

                                 unsubordinated indebtedness. The registered

                                 trade payables. We are primarily a holding
                                 company and most of our operations are

CERTAIN COVENANTS.............   The indenture governing the notes contains
                                 covenants limiting our ability and the ability
                                 of our subsidiaries to, among other things:

                                 - incur debt secured by liens;

                                 - guarantee debt; and

                                 - merge or consolidate or sell all or
                                   substantially all of our assets.

USE OF PROCEEDS...............   We will not receive any cash proceeds upon the
                                 completion of the exchange offer.

FURTHER ISSUANCES.............   We may from time to time, without notice to or
                                 the consent of the holders of notes, create and
                                 issue additional notes ranking equally and
                                 ratably with the notes. Such further notes may
                                 be issued under the indenture relating to the
                                 notes offered hereby, and may vote with the
                                 notes offered hereby on matters affecting all
                                 noteholders.

FORM OF REGISTERED NOTES......   The registered notes to be issued in the
                                 exchange offer will be represented by one or
                                 more global securities deposited with The Bank

                                        9


                                 under the heading "Description of the
                                 Registered Notes -- Form of Registered Notes"
                                 occurs.

                                 Instead, beneficial interests in the registered
                                 notes to be issued in the exchange offer will
                                 be shown on, and a transfer of these interests
                                 will be effected only through, records
                                 maintained in book-entry form by DTC with
                                 respect to its participants.

RISK FACTORS..................   You should refer to the section entitled "Risk
                                 Factors" for a discussion of material risks you
                                 should carefully consider before deciding to
                                 invest in the notes.

                      RATIOS OF EARNINGS TO FIXED CHARGES

     The following table sets forth our ratios of earnings to fixed charges for
the periods indicated.

<Table>

    YEAR ENDED DECEMBER 31,
- --------------------------------
2001   2000   1999   1998   1997

</Table>

     --------------------

     (1) For the year ended December 31, 2001, fixed charges exceeded earnings
         by approximately $37.1 million. Earnings were net of restructuring and
         transformation charges of approximately $74.2 million in 2001. Without
         these restructuring and transformation charges, our ratio of earnings
         to fixed charges would have been 2.0x for 2001.

                                  RISK FACTORS

     Before you participate in the exchange offer, you should carefully consider
the risks described below and the other information included or incorporated by
reference in this prospectus.

RISKS RELATING TO THE EXCHANGE OFFER

THERE MAY BE NO ACTIVE TRADING MARKET FOR THE REGISTERED NOTES TO BE ISSUED IN
THE EXCHANGE OFFER.

     The registered notes are a new issue of securities for which there is no
established market. Accordingly, any or all of the following may occur:

     - no liquid market for the registered notes may develop;

     - you may be unable to sell your registered notes; or

     - the price at which you will be able to sell the registered notes may be
       lower than their principal amount or purchase price.

     If a public market were to exist, the registered notes could trade at
prices that may be higher or lower than their principal amount or purchase
price, depending on many factors, including prevailing interest rates, the
market for similar notes, and our financial performance. We do not intend to
list the registered notes to be issued to you in the exchange offer on any
securities exchange or to seek approval for quotations through any automated
quotation system. No active market for the registered notes is currently
anticipated.

THE NOTES ARE EFFECTIVELY SUBORDINATED TO THE DEBT OF OUR SUBSIDIARIES, WHICH
COULD ADVERSELY AFFECT YOUR RIGHTS TO RECEIVE PAYMENTS OF INTEREST AND PRINCIPAL
ON THE NOTES.

     We are primarily a holding company and most of our operations are conducted
by our subsidiaries. None of our subsidiaries has guaranteed our obligations to
make payments on the notes. In the event of a bankruptcy, liquidation or
reorganization of any of our subsidiaries, their creditors will generally be
entitled to payment of claims from their assets before any of those assets are
made available for a distribution to us for any purpose, including payments on
the notes. As a result, the notes will be effectively subordinated to the
liabilities of our subsidiaries. In the event of a bankruptcy, liquidation or
reorganization of any of our subsidiaries, we and our creditors, including the
holders of the notes, will have no right to proceed against the assets of our
subsidiaries or to cause the liquidation or bankruptcy of these subsidiaries
under bankruptcy laws.

RISKS RELATED TO OUR BUSINESS

WE HAVE EXPERIENCED AND MAY CONTINUE TO EXPERIENCE DECLINES IN REVENUE,
OPERATING PROFIT AND NET INCOME, WHICH MAY ADVERSELY AFFECT OUR ABILITY TO MAKE
PAYMENTS OF INTEREST AND PRINCIPAL ON THE NOTES.

     We experienced a decline in total sales to $2.13 billion in 2001 from $2.46
billion in 2000, and recorded an operating profit of $54.3 million in 2001 as
compared with an operating profit of $207.8 million in 2001 and a net loss of
$25.0 million in 2001 as compared to net income of $132.5 million in 2000 and
$300.2 million in 1999. On April 17, 2002, we announced total sales, operating
profit and a net loss of $493.1 million, $3.2 million and $11.1 million,
respectively, for the quarter ended March 31, 2002. Based on the apparent
continuing weakness and uncertainty in the U.S. and most global economies, we
expect 2002 to continue to be a difficult year for us. If declines in our
operating results continue, our ability to make payments of interest and
principal on the notes could be impaired.

                                        11


THE CYCLICAL NATURE OF THE INDUSTRIES IN WHICH OUR CUSTOMERS OPERATE CAUSE
DEMAND FOR OUR PRODUCTS TO BE CYCLICAL, CREATING UNCERTAINTY REGARDING OUR
FUTURE PROFITABILITY.

     Various changes in general economic conditions affect the industries in
which our customers operate. These changes include decreases in the rate of
consumption or use of our customers' products due to economic downturns. Other
factors causing fluctuation in our customers' positions are changes in market
demand, lower overall pricing due to national and international overcapacity,
currency fluctuations, lower priced imports and increases in use or decreases in
prices of substitute materials. As a result of these factors, demand for our
products and, therefore, our profitability has been and may in the future be
subject to significant fluctuation. In particular, our profitability may be
adversely affected by our inability to quickly adjust our cost structure to
correspond to changing market conditions, because a significant portion of our
operating costs are fixed in the near-term. A continuing decline in our
profitability could impair our ability to make payments of interest and
principal on the notes.

OUR SUBSTANTIAL INDEBTEDNESS AND RELATED FUTURE DEBT SERVICE REQUIREMENTS COULD
ADVERSELY AFFECT OUR ABILITY TO SATISFY OUR OBLIGATIONS WITH RESPECT TO THE
NOTES AND OUR FINANCIAL FLEXIBILITY GENERALLY.

     At March 31, 2002 we had a total indebtedness of $525.4 million and the
ability (subject to satisfaction of borrowing conditions) to borrow up to $325
million under our revolving credit facility. This indebtedness and our related
future debt service requirements could have important consequences to us and to
you. For example, it could:

     - make it more difficult for us to satisfy our obligations with respect to
       the notes;

     - increase our vulnerability to general adverse economic and industry
       conditions;

     - require us to dedicate a substantial portion of our cash flow from
       operations to payments on our indebtedness, thereby reducing the
       availability of our cash flow to fund working capital, capital
       expenditures and other general corporate purposes;

     - limit our flexibility in planning for, or reacting to, changes in our
       businesses and the industries in which we operate; and

     - place us at a competitive disadvantage.

THE CURRENT TREND OF PRICE DEFLATION FOR MANY COMMODITY PRODUCTS HAS ADVERSELY
AFFECTED PRICES FOR OUR PRODUCTS AND MAY CONTINUE TO DO SO.

     Prices for commodity products such as commodity grades of specialty
materials, including stainless steel, currently are subject to a trend of price
deflation. Because we produce commodity products such as these, our revenues and
operating results have been and may continue to be adversely affected by a
deflationary price environment for these products. For example, average prices
per net finished ton of our commodity stainless steel flat-rolled products
decreased 16% in 2001 as compared to 2000. Reduction in the demand for our
commodity products by our customers may continue to cause our profitability to
decline and could impair our ability to make payments of interest and principal
on the notes.

ENERGY RESOURCES AND RAW MATERIALS MARKETS ARE SUBJECT TO CONDITIONS THAT CREATE
UNCERTAINTY IN THE PRICES AND AVAILABILITY OF ENERGY RESOURCES UPON WHICH WE
RELY.

     We rely upon third parties for our supply of energy resources consumed in
the manufacture of our products. The prices for and availability of electricity,
natural gas, oil and other energy resources are subject to volatile market
conditions. These market conditions often are affected by political and economic
factors beyond our control. Disruptions in the supply of our energy resources
could temporarily impair our ability to manufacture our products for our
customers. Further, increases in our energy costs, or changes in costs relative
to energy costs paid by our competitors, has and may continue to adversely
affect our profitability and could impair our ability to make payments of
interest and principal on the notes. For example, in 2001 we incurred
substantially higher energy costs in the Flat-Rolled Products and High
Performance Metals segments compared to prior years. On a

                                        12


volume-adjusted basis, the Flat-Rolled Products segment incurred $14.3 million
in higher energy costs in 2001 compared to 2000. The High Performance Metals
segment had $14.1 million in higher energy costs for the first nine months of
2001 compared to the comparable prior year period. We use approximately 10 to 12
million MMBtus of natural gas annually, depending on business conditions, in the
manufacture of our products. These purchases of natural gas expose us to the
risk of higher gas prices. For example, a hypothetical $1.00 per MMBtu increase
in the price of natural gas would result in increased annual energy costs of
approximately $10 to $12 million. These factors also impact our ability to
implement or maintain energy surcharges and influence the business decisions
made by our suppliers and customers. To the extent that these uncertainties
cause our suppliers and customers to be more cost sensitive, increased energy
prices may have an adverse effect on our results of operations and financial
condition and could impair our ability to make payments of interest and
principal on the notes.

     We rely to a substantial extent on outside vendors to supply us with
certain raw materials that are critical to the manufacture of our products.
Purchase prices and availability of these critical raw materials are subject to
volatility. At any given time, we may be unable to obtain an adequate supply of
these critical raw materials on a timely basis, on price and other terms
acceptable to us, or at all.

     If our suppliers increase the price of our critical raw materials, we may
not have alternative sources of supply. In addition, to the extent that we have
quoted prices to our customers and accepted customer orders for our products
prior to purchasing necessary raw materials, we may be unable to raise the price
of our products to cover all or part of the increased cost of the raw materials.
For example, we generally use more than 40,000 tons of nickel each year. A
hypothetical price increase of $1.00 per pound in nickel prices would result in
increased annual nickel costs of approximately $80 million.

     The manufacture of some of our products is a complex process and requires
long lead times. As a result, we have in the past and may in the future
experience delays or shortages in the supply of raw materials. If we are unable
to obtain adequate and timely deliveries of our required raw materials, we may
be unable to timely manufacture sufficient quantities of our products. This
could cause us to lose sales, incur additional costs, delay new product
introductions and suffer harm to our reputation.

     While we enter into raw materials and energy futures contracts from time to
time to hedge our exposure to price fluctuations, we cannot be certain that our
hedge position adequately reduces our exposure. We believe that we have adequate
controls to monitor these contracts, but we may not be able to accurately assess
our exposure to price volatility in the markets for critical raw materials. In
addition, although we occasionally use raw materials surcharges to offset the
impact of increased costs, competitive factors in the marketplace can limit our
ability to institute surcharges, and there can be a delay between the increase
in the price of raw materials and the realization of the benefit of our
surcharges.

     We acquire certain important raw materials that we use to produce our
specialty materials, including nickel, titanium sponge and ammonia
paratungstate, from foreign sources. Some of these sources operate in countries
that may be subject to unstable political and economic conditions. These
conditions may disrupt supplies or affect the prices of these materials.

WE ARE SUBJECT TO EXTENSIVE ENVIRONMENTAL REGULATION, AND VIOLATIONS OF OR
LIABILITIES UNDER THESE REGULATIONS COULD HAVE A MATERIAL ADVERSE EFFECT ON US.

     We are subject to various domestic and international environmental laws and
regulations that govern our discharge of pollutants into the air or water, our
management and disposal of hazardous substances, and which may require us to
investigate and remediate the effects of the release or disposal of materials at
sites associated with past and present operations, including sites at which we
have been identified as a potentially responsible party under the Comprehensive
Environmental Response Compensation and Liability Act and comparable state laws.
We could incur substantial cleanup costs, fines and civil or criminal sanctions,
third party property damage or personal injury claims as a result of violations
or liabilities under these laws or non-compliance with environmental permits
required at our facilities. We currently are involved in the investigation and
remediation of number of our current and former sites as well as third party
locations. The resolution in any reporting period of one or more of these
matters could have a material adverse effect on our results of operations for
that period. In
                                        13


addition, future developments, administrative actions or liabilities relating to
environmental matters could have a material adverse effect on our financial
condition or results of operations and impair our ability to make payments of
interest and principal on the notes.


A CONTINUATION OF THE DECLINE IN U.S. EQUITY MARKETS COULD AFFECT OUR ABILITY TO
UTILIZE EXCESS PENSION ASSETS TO FUND RETIREE MEDICAL COSTS FULLY, COULD REQUIRE
US TO RECOGNIZE A MINIMUM PENSION LIABILITY AND RECORD A BALANCE SHEET CHARGE TO
STOCKHOLDERS' EQUITY, AND COULD REQUIRE US TO MAKE CASH CONTRIBUTIONS TO OUR
PENSION PLAN ON AN ONGOING BASIS, WHICH COULD IMPAIR OUR ABILITY TO MAKE
PAYMENTS OF INTEREST AND PRINCIPAL ON THE NOTES.


     Our defined benefit pension plan is fully funded with assets in excess of
the projected benefit obligation. Under current Internal Revenue Code
provisions, certain amounts that we pay for retiree health care benefits may be
reimbursed annually from the excess pension plan assets. In 2001, we recovered
$35 million under these provisions, all in the second quarter. While not
affecting reported operating profit, cash flow from operations increased by the
recovered amount. Our ability to be reimbursed fully for retiree medical costs
in future years is dependent upon the level of pension surplus, as computed
under the code provisions of the Internal Revenue Service, as of beginning of
each year. The level of pension surplus and the value of pension assets less
pension obligations change constantly due to the volatility of pension asset
investments and, to a lesser extent, benefit enhancements. Due to the decline in
the U.S. equities market, the pension overfunded status at the beginning of 2002
is below the threshold required to fully reimburse us for retiree medical costs
in 2002. This will negatively impact our after-tax cash flow in 2002 by
approximately $22 million. The ability to resume reimbursement for retiree
health care costs beyond 2002 from excess pension plan assets will depend upon
the performance of the pension investments, and any change in the Internal
Revenue Code regulations pertaining to reimbursement of retiree health care
costs from pension surplus.

     Accounting standards require that a minimum pension liability be recorded
if the value of pension assets are less than the accumulated pension benefit
obligation at the end of the year. Based upon the value of pension assets as of
December 31, 2001, we would not be required to record such a minimum pension
liability. However, if the value of pension assets were to decline to a level
below the accumulated pension benefit obligation, we would be required to record
a minimum pension liability and record a balance sheet charge to shareholders'
equity for the value of the prepaid pension asset, currently recognized on the
balance sheet, and the required minimum pension liability, net of deferred
taxes.


     The pension plans are funded in accordance with the requirements of the
Employee Retirement Income Security Act of 1974, as amended, and the Internal
Revenue Service. If the value of the pension assets were to significantly
decline, we could be required to make cash contributions to the pension plan
trust in amounts that could be significant.


     If we were required to fund significant retiree medical costs or pension
obligations from cash flow from operations, our ability to make payments of
interest and principal on the notes could be impaired.

WE HAVE EXPERIENCED IN THE PAST AND MAY EXPERIENCE IN THE FUTURE LABOR DISPUTES
THAT COULD HAVE A MATERIAL ADVERSE EFFECT ON OUR OPERATIONS AND PROFITABILITY.

     Approximately half of our workforce is covered by various collective
bargaining agreements, principally with the United Steelworkers of America.
Generally, agreements that expire may be terminated after notice by the USWA.
After such a termination, the USWA may authorize a strike. A strike by the
employees covered by one or more of the collective bargaining agreements could
materially adversely affect our operating results. On September 4, 2001, workers
at our Wah Chang facility began a strike. On March 22, 2002 we announced that
our Wah Chang facility and the USWA had reached a new six-year labor agreement
that became effective on April 1, 2002. In the future, we may not succeed in
concluding new collective bargaining agreements with the USWA or other unions to
replace those that expire. The effect of future labor disputes could have a
materially adverse impact on us and impair our ability to make payments of
interest and principal on the notes.

                                        14


OUR ABILITY TO OBTAIN INSURANCE FOR VARIOUS RISKS, OR ON ACCEPTABLE TERMS, IS
UNCERTAIN.

     We obtain various kinds of insurance as may be needed to conduct our
business. Such insurance may include all risk property, workers' compensation,
third party liability and other coverages deemed necessary and prudent. In view
of the events of September 11, 2001 and for other reasons associated with the
world economies, we cannot predict the conditions under which we will be able to
obtain insurance coverage in the future, the level of premiums, the size of
deductibles, or any other adjustments to the cost of coverage of insurance.

VARIABLE RATE INTEREST ON OUR INDEBTEDNESS EXPOSES US TO THE RISK OF HIGHER
INTEREST COSTS IN THE FUTURE.

     At December 31, 2001, we had approximately $124 million of variable
interest rate debt outstanding with an average interest rate of approximately
2.9 percent. Since the interest rate on this debt varies with the short-term
market rate of interest, we are exposed to the risk that these interest rates
may increase. For example, a hypothetical 1 percent increase in the annual rate
of interest on $124 million of outstanding variable rate debt would result in
increased annual interest costs of $1.2 million. A substantial increase in
interest costs could impair our ability to make payments of interest and
principal on the notes.

BECAUSE EXPORT SALES CONSTITUTE A SIGNIFICANT PERCENTAGE OF OUR SALES, RISKS
ASSOCIATED WITH EXPORT SALES COULD HAVE A MATERIAL ADVERSE EFFECT ON OUR
OPERATING RESULTS.

     In 2001, international sales accounted for approximately 23 percent of our
total revenues, and we believe that export sales will continue to account for a
significant percentage of our future revenues. Risks associated with export
sales include:

     - political and economic instability, including weak conditions in the
       world's economies;

     - accounts receivable collection;

     - export controls;

     - changes in legal and regulatory requirements;

     - policy changes affecting the markets for our products;

     - changes in tax laws and tariffs; and

     - exchange rate fluctuations, which may affect sales to international
       customers and the value of profits earned on export sales when converted
       into dollars.

     Any of these factors could have a material adverse effect on our results of
operations and impair our ability to make payments of interest and principal on
the notes.

WE FACE RISKS RELATED TO INVESTIGATIONS OF OUR PERFORMANCE UNDER U.S. GOVERNMENT
CONTRACTS, WHICH MAY RESULT IN THE PAYMENT OF MONIES, OR ADVERSELY AFFECT OUR
ABILITY TO PERFORM UNDER THESE CONTRACTS.

     One of our operating companies performs work under U.S. Government
contracts. We, like other government contractors, are subject to various audits,
reviews and investigations relating to compliance with laws. Various claims have
been asserted against us, principally related to one of our former operations.
Depending on the outcome, such proceedings could result in fines, penalties,
compensatory and treble damages or the cancellation or suspension of payments
under the contract. Should the business unit or division involved be charged
with wrongdoing, or should the U.S. Government determine that the unit or
division is not a "presently responsible contractor," that unit or division, and
conceivably our company as a whole, could be temporarily suspended or, in the
event of a conviction, debarred for up to three years from receiving new
government contracts or government-approved subcontracts. These proceedings may
result in damages, fines and penalties if the charges are proven or settlement
negotiated and we could expend substantial amounts in defending against such
claims which could impair our ability to make payments of interest and principal
on the notes.

                                        15


THE SEPTEMBER 11, 2001 TERRORIST ATTACKS AND THE POSSIBILITY OF ADDITIONAL
ATTACKS HAVE ADVERSELY AFFECTED THE U.S. AND OTHER ECONOMIES AND ARE LIKELY TO
ADVERSELY AFFECT OUR OPERATING RESULTS.

     The September 11, 2001 terrorist attacks and the possibility of additional
attacks have adversely affected the U.S. and other economies and are likely to
adversely affect our operating results. As a result, demand for our products and
our profitability could decline, perhaps significantly. In particular, the
events of September 11 resulted in sharply reduced air travel, which led to
curtailed or delayed new plane orders and the idling of large portions of the
fleets of commercial airlines. A significant portion of the sales of our High
Performance Metals Group products are made to customers in the aerospace
industry, and we expect that reduced orders from those customers will adversely
affect our results of operations, which could impair our ability to make
payments of interest and principal on the notes.

WE PLAN TO CONTINUE TO IMPLEMENT ACQUISITION AND DISPOSITION STRATEGIES THAT
INVOLVE A NUMBER OF INHERENT RISKS, ANY OF WHICH COULD CAUSE US NOT TO REALIZE
ANTICIPATED OPERATING RESULTS.

     We intend to continue to strategically position our businesses in order to
improve our ability to compete. We plan to do this by seeking specialty niches,
expanding our global presence, acquiring businesses complimentary to existing
strengths and continually evaluating the performance and strategic fit of
exiting business unit dispositions. As a result, the relative makeup of our
businesses is subject to change. Acquisitions, joint ventures and other business
combinations involve various inherent risks, such as assessing accurately the
value, strengths, weaknesses, contingent and other liabilities and potential
profitability of acquisition or other transaction candidates; the potential loss
of key personnel of an acquired business; our ability to achieve identified
financial and operating synergies anticipated to result from an acquisition or
other transaction; and unanticipated changes in business and economic conditions
affecting an acquisition or other transaction. International acquisitions and
other transactions could also be affected by export controls, exchange rate
fluctuations, domestic and foreign political conditions and deteriorations in
domestic and foreign economic relations.

     We may be unable to realize, or do so within any particular time frame, the
cost reductions, cash flow increases or other synergies expected to result from
acquisitions, joint ventures and other transactions or investments we may
undertake, or be unable to generate additional revenue to offset any
unanticipated inability to realize such expected synergies. Realization of the
anticipated benefits of acquisitions or other transactions could take longer
than expected, and implementation difficulties, market factors and
deteriorations in domestic or global economic conditions could alter the
anticipated benefits, which could impair our ability to make payments of
interest and principal on the notes.

                           FORWARD-LOOKING STATEMENTS

     This prospectus contains forward-looking statements. Forward-looking
statements include, without limitation, those statements related to anticipated
business, economic and market conditions; operational actions taken to respond
to market conditions; sales and earnings, financial condition, financial
performance and growth and return on capital; prices, price increases and the
effect of price increases on performance and product demand; raw material and
energy costs, expected capital expenditures, cost reductions, including energy
initiatives, anticipated cost savings, including the anticipated time periods in
which savings may be realized; capital investments and the impact of investments
on our capabilities; working capital, cash flow, dividends or potential
repurchases of our stock; projected pension surplus, excess pension income
(expense) and reimbursement of retiree health care expenditures; realization of
deferred income tax assets; the ratification of labor agreements as well as the
expected benefits and costs under those agreements; anticipated effects of
acquisitions, joint ventures or other business combinations on earnings; the
outcome of any government inquiries, litigation or other proceedings related to
government contracts or other matters; safety performance; and future
environmental costs. These statements are based on current expectations or
beliefs concerning various future events that involve a number of risks and
uncertainties, many of which we are unable to predict or control. Actual results
or performance may differ materially from any future results or performance
anticipated based on management's current expectations contained in such
forward-looking statements.

                                        16


     The factors discussed under the heading "Risk Factors" and elsewhere in
this prospectus are not necessarily all of the important factors that could
cause our results to differ materially from expected results. Other factors,
such as the general state of the economy, could also cause actual results to
vary materially from expected results. Forward-looking statements speak only as
of the date they were made and we undertake no obligation to update them,
whether as a result of new information, future events or otherwise. You are
advised, however, to consult any additional disclosures we may make in our
reports filed with the Commission.

                                USE OF PROCEEDS

     We will not receive any cash proceeds from the completion of the exchange
offer. The net proceeds of approximately $293.3 million from the issuance of the
old notes were used to repay a portion of our outstanding short-term
indebtedness.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

OVERVIEW

     We are one of the largest and most diversified producers of specialty
materials in the world. We operate in three business segments: Flat-Rolled
Products, High Performance Metals and Industrial Products. Information with
respect to each business segment is presented separately below.

     2001 was a difficult and challenging year for us. In spite of weak
conditions in many of our markets, significant accomplishments included
improvements in safety, cost reductions, and working capital management.

     - Cash flow from operations in 2001 was $122.8 million.

     - Managed working capital (gross inventory and accounts receivable less
       accounts payable) was reduced by $127.1 million, beating the $70 million
       managed working capital reduction goal by over 80 percent.

     - Cost savings amounted to $115 million in 2001, exceeding the $110 million
       goal.

     - In late December 2001, we strengthened our capital base by issuing $300
       million of new 10-year notes and arranging a new $325 million revolving
       bank credit facility.

     - As a result of our continuing focus on safety, in 2001 the OSHA Total
       Recordable Incident Rate improved 17 percent and the Lost Day Case Rate
       improved 16 percent compared to 2000. Over the last two years, both
       measures of safety have improved by over 40 percent.

     Looking forward, based on the apparent continuing weakness and uncertainty
in the U.S. and most global economies as we enter 2002, we expect the year to be
difficult. Therefore, our top financial priority is to continue to reduce costs
and generate cash. Cost savings opportunities of $100 million have been
identified for 2002. The current 2002 capital expenditure plan for operational
necessities and for continuation of capital programs which commenced in 2001 is
approximately $50 million, compared to capital investments totaling $104 million
in 2001. Through our Operational Excellence initiatives, we will stay focused on
safety, customer satisfaction, cost reduction and reducing managed working
capital. Our goal for 2002 is to further reduce managed working capital by $65
million. Success in achieving these goals should give us the financial capacity
to weather the economic recession and emerge strongly when the economy recovers.

     Our Flat-Rolled Products segment produces, converts and distributes
stainless steel, nickel-based alloys and superalloys, and titanium and
titanium-based alloys in sheet, strip, plate and Precision Rolled Strip(R)
products as well as silicon electrical steels and tool steels. The companies in
this segment include Allegheny Ludlum, Allegheny Rodney, Rome Metals, and
Allegheny Ludlum's 60 percent interest in the Chinese joint venture company
known as Shanghai STAL Precision Stainless Steel Company Limited ("STAL").

     Our High Performance Metals segment produces, converts and distributes
nickel- and cobalt-based alloys and superalloys, titanium and titanium-based
alloys, zirconium, hafnium, niobium, tantalum and other specialty materials,
primarily in slab, ingot, billet, bar, rod, wire and coil forms, seamless tube
forms and zirconium chemicals. The companies in this segment include Allvac,
Allvac Ltd (U.K.) and Wah Chang.

     Our Industrial Products segment's principal business produces tungsten
powder, tungsten carbide materials and carbide cutting tools. This segment also
produces large grey and ductile iron castings and carbon alloy steel and
non-ferrous forgings. The companies in this segment are Metalworking Products,
Casting Service and Portland Forge.

     Set forth below are consolidated revenues and EBITDA for these three
business segments for the years ended December 31, 2001, 2000 and 1999,
respectively:

     When we refer to "energy costs" in the following discussion, we are
referring to costs of electricity and natural gas. When we refer to "average
prices" we are referring to sales of a particular product divided by the number
of tons or pounds, as applicable, of that product shipped. All references to
amounts shipped are calculated in tons or pounds, as applicable.

RESULTS OF OPERATIONS

     Our sales were $2.13 billion in 2001, $2.46 billion in 2000 and $2.30
billion in 1999. International sales represented approximately 23 percent of
sales in 2001, 18 percent in 2000, and 20 percent in 1999.

     Operating profit was $54.3 million in 2001, $207.8 million in 2000, and
$184.4 million in 1999. In 2001, we had a net loss from continuing operations of
$25.2 million, which included after-tax charges of $47.8 million related to the
permanent idling of the Houston, PA stainless steel melt shop, workforce
reductions and other asset impairments. For 2000 and 1999, we had net income
from continuing operations of $132.5 million and $111.0 million, respectively.

     We operate in three business segments: Flat-Rolled Products, High
Performance Metals and Industrial Products. Information with respect to our
business segments is presented below.

  2001 Compared to 2000

     Sales for the Flat-Rolled Products segment decreased 24.6 percent in 2001
compared to 2000 resulting in an operating loss of $38.1 million for the year.
During 2001, operating results were severely impacted by very low demand and
poor prices for many stainless steel products. Finished tons shipped in 2001
declined by 18 percent to 498,066 tons compared to shipments of 608,601 tons for
2000. The average price of flat-rolled products in

                                        20


2001 decreased by 9 percent to $2,162 per ton compared to $2,365 per ton in the
same 2000 period. Commodity product shipments in the segment (including
stainless steel hot roll and cold roll sheet, stainless steel plate and silicon
electrical steel, among other products) decreased 20 percent compared to 2000.
Average prices for commodity products decreased 16 percent during the same
period. These decreases were primarily attributable to continued weak demand for
stainless steel sheet and plate due to the weak U.S. industrial economy.
High-value product shipments in the segment (including strip, Precision Rolled
Strip(R), super stainless steel, and nickel alloy and titanium products)
decreased 12 percent compared to 2000, while average prices for high-value
products decreased 1 percent. Certain of these high-value products are used
largely in the automotive industry and capital goods markets, both of which were
impacted by the weak U.S. economy. Increased international sales, primarily of
Precision Rolled Strip(R) products, in Europe and Asia were offset by the
overall decline in shipments of high-value products in the U.S.

     Operating results were also adversely affected by $14.3 million in higher
energy costs, on a volume-adjusted basis, in 2001 compared to the prior year. In
addition, during 2001, accounts receivable reserves were increased by $7.3
million in recognition of the decline in the economy and the reduced
availability of credit.

     The decline in operating results was partially offset by ongoing cost
reductions in the segment's Allegheny Ludlum operation, including a 10 percent
salaried workforce reduction that was completed in the first quarter of 2001 and
a further 5 percent reduction in staff at the end of 2001. Cost reductions for
2001 totaled approximately $80 million.

     During the 2001 fourth quarter, we decided to permanently idle the melt and
associated service operations located at our Houston, PA facility. We had
determined that this facility could no longer be operated economically in the
highly competitive global stainless steel market. This cost reduction action
affected approximately 225 employees. A pre-tax charge of $70.0 million,
primarily non-cash, for the related asset impairments, employee benefits, and
other closure costs was recorded in the 2001 fourth quarter. These expenses are
presented as restructuring costs on the statements of operations and are not
included in the results for the segment. These cost reduction actions are
expected to result in annual pre-tax cost savings of approximately $12 million.

  2000 Compared to 1999

     Sales and operating profit for the segment increased 11.4 percent and 40.4
percent, respectively, in 2000 compared to 1999.

     The increase in sales was a result of improved pricing and higher demand
for stainless steel products during the first three quarters of the year.
Shipments of finished flat-rolled products were 608,601 tons in 2000 compared to
592,619 tons in 1999.

     The average selling prices of finished flat-rolled products increased to
$2,365 per ton in 2000 from $2,081 per ton in 1999. This increase was due
principally to the impact of revised raw materials surcharge base levels,
primarily for nickel and chrome, and an improved product mix. High value margin
product shipments increased 13 percent in 2000.

     Operating profit increased 40.4 percent to $119.6 million in 2000 primarily
due to revised raw material surcharge base levels and improved product mix
towards higher margin products. Tight operating cost controls and cost reduction
efforts continued in the segment. In the fourth quarter of 2000, Allegheny
Ludlum announced a 10 percent salaried workforce reduction, which was
subsequently completed in the first quarter of 2001. The segment's fourth
quarter 2000 operating profit was reduced by $7.0 million, compared to the
fourth quarter of 1999, due to increased natural gas costs.

     The STAL joint venture in Shanghai, China completed its first year of
commercial production of Precision Rolled Strip(R) stainless steel strip in
2000.

  2001 Compared to 2000

     Sales for the High Performance Metals segment increased 4.9 percent in 2001
compared to 2000 as a result of continued strong shipments of high-value
products to the aerospace, electrical energy, and oil and gas markets due, in
part, to strong order backlog built at the end of 2000 and the first half of
2001. Shipments of nickel-based and specialty steel alloys increased 11 percent
and prices increased 8 percent compared to 2000. While titanium mill products
shipments decreased 7 percent, prices increased 8 percent compared to 2000.
Shipments and prices for exotic alloys were down 6 percent compared to 2000.

     Operating profit for 2001 increased 23.3 percent compared to 2000 primarily
as a result of higher prices due to strong market conditions, combined with
favorable product mix and efforts to reduce costs. Cost reductions for 2001
totaled approximately $27 million. However, operating profit was adversely
affected by $14.1 million in higher energy costs in the first nine months of
2001 compared to the prior year.

     During the 2001 third quarter, the United Steelworkers of America (USWA)
employees at the Wah Chang facility, located in Albany, Oregon, went on strike
after the union membership rejected the previously negotiated tentative
contract. After a brief shutdown, and while we and the USWA continued
discussions, we resumed full operation of the plant with management and salaried
employees and replacement workers. The Wah Chang facility is involved in the
production of exotic alloys including zirconium and niobium, and the strike does
not impact other operations.

     During the 2001 fourth quarter, we divested the North American operations
of our titanium distribution company, Titanium Industries Inc. Results of
operations for this business for 2001 and proceeds from the disposition of this
business were not material to us.

     Backlog of confirmed orders for the segment was approximately $350 million
at December 31, 2001 and approximately $375 million at December 31, 2000. We
expect demand for products used in commercial aerospace, which historically has
been the segment's largest end-use market, to decrease in 2002 due to weaker
market conditions, which have been exacerbated by the tragic events of September
11, 2001. As a result, in the 2001 fourth quarter we announced workforce
reductions affecting approximately 220 employees at the Allvac and Allvac Ltd.
operations. In connection with these reductions, which were completed in the
2002 first quarter, we recorded a pre-tax charge of $1.8 million for the related
employee benefits costs. These expenses are presented as restructuring costs on
the statement of operations and are not included in the results for the segment.
These cost reduction actions are expected to result in annual pre-tax cost
savings of approximately $5 million.

  2000 Compared to 1999

     Sales for the High Performance Metals segment increased 1.8 percent in 2000
compared to 1999. The increased sales reflected increased demand for
nickel-based alloys and superalloys and specialty steel alloys from growing
markets for electrical power generation turbines and biomedical products, and
improved conditions in aerospace and oil and gas markets. In addition, shipments
were strong for niobium-titanium alloys for superconducting applications,
nickel-titanium shape memory alloys for cellular phones, nickel-titanium super-
elastic alloys for the medical industry, and hafnium alloys used in the
production of superalloys for aerospace applications. However, shipments of
zirconium alloy products were lower in 2000 as a result of weaknesses in the
chemical processing and commercial nuclear markets. Shipments for titanium
products improved despite overall weakness in industrial markets, including
chemical processing, which adversely affected pricing.

     Operating profit decreased 23.6 percent in 2000 compared to 1999. Increased
energy costs of $9.0 million in the fourth quarter, primarily for electric power
at the Wah Chang operation in Oregon, contributed to the decline in operating
profit. Operating profit was also adversely impacted by weaker results for
zirconium and titanium
                                        22


and by higher operating costs at our titanium sponge facility, which was
permanently idled in the first half of 2001.

     In 2000, due to persistent weak market conditions, together with our
ability to enter into long-term supply agreements for the purchase of titanium
sponge at prices below our manufacturing cost, we decided to discontinue
producing titanium sponge. As a result, in the fourth quarter of 2000, we
recorded a charge of $20.0 million for asset impairment, employee termination
benefits, and contractual costs to exit the business related to the idling of
high-cost titanium sponge production assets located in Albany, Oregon. We ceased
production of titanium sponge in the first half of 2001.

  2001 Compared to 2000

     Sales and operating profit for the Industrial Products segment decreased
4.7 percent and 52.1 percent, respectively, in 2001 compared to 2000. Weak
demand from most U.S. industrial markets negatively impacted operating results
for all businesses in the segment. In addition during 2001, accounts receivable
reserves were increased by $1.7 million in recognition of the decline in the
economy and the reduced availability of credit. The decline in operating results
was partially offset by ongoing efforts to reduce costs, which totaled
approximately $9 million in 2001.

  2000 Compared to 1999

     Sales and operating profit for the Industrial Products segment increased
1.5 percent and 77.9 percent, respectively, in 2000 compared to 1999. These
increases reflect improved performance at Metalworking Products due to stronger
industrial demand in early 2000 and the impact of cost reduction initiatives. In
addition, operating results for the second half of the year reflect the
acquisition of a tungsten carbide products operation. During the second quarter
of 2000, we exited the molybdenum and tungsten mill products business, which had
1999 sales of approximately $15.0 million. The segment's forgings and castings
businesses experienced a decrease in sales and operating profit in 2000 due
primarily to continued weak conditions in the transportation, farm equipment and
wind power generation markets.

  RESTRUCTURING AND TRANSFORMATION COSTS AND OTHER COSTS, NET OF GAINS ON ASSET
  SALES

  Restructuring and Transformation Costs

     Restructuring and transformation costs were $74.2 million, $29.5 million
and $5.6 million in 2001, 2000 and 1999, respectively.


     In 2001, we recorded a charge of $74.2 million related to the permanent
idling of the Houston, PA stainless steel melt shop, workforce reductions and
other asset impairments. Of this aggregate charge, $55.6 million related to the
Houston, PA stainless steel melt shop, which was permanently idled in the 2001
fourth quarter, and other asset impairments; $9.8 million related to pension and
termination benefits; $5.8 million related to severance and personnel costs; and
$3.0 million related to contractual obligations and other exit costs. The
workforce reductions affected approximately 520 employees across all of the
Company's business segments and headquarters operations, and were substantially
complete by the end of 2001. These cost reduction actions are estimated to
provide annual pre-tax cost savings of approximately $19 million in 2002. We do
not anticipate that the permanent idling of the Houston, PA stainless steel melt
shop will result in reduced sales as we have the ability to increase our melt
output using our existing facilities and can procure additional semi-finished
material, if needed, on the world market, where excess stainless steel melt
capacity currently exists.


                                        23


     Of the $74.2 million restructuring charge recorded in 2001, $4.0 million,
net of tax benefits, is expected to result in expenditures of cash, which will
be paid in 2002. Cash to meet these obligations will be generated from one or
more of the following sources: internally generated funds from operations,
current cash on hand, or borrowings under existing credit lines and our
commercial paper program.

     In 2000, we recorded restructuring and transformation charges of $29.5
million. The 2000 charge included $13.3 million for asset impairments, and $6.7
million for employee termination benefits, primarily severance pay, and other
contractual obligations related to the decision in the 2000 fourth quarter to
permanently idle the high-cost titanium sponge production assets of the High
Performance Metals segment. We ceased titanium sponge production in the first
half of 2001, and costs associated with operating the facility in 2001 were
included in results of operations as they were incurred. The 2000 charge also
included $3.1 million related to the 10 percent salaried workforce reduction at
Allegheny Ludlum. The staffing reductions were made pursuant to a cost reduction
plan, which resulted from a management study undertaken in an effort to remain
cost competitive. The salaried workforce was notified by management of the
planned workforce reduction and of the availability of termination benefits
prior to December 31, 2000. The reduction in workforce was completed in the 2001
first quarter, and resulted in approximately $11 million in cost savings in
2001. In addition, restructuring and transformation charges for 2000 included
$6.4 million for costs related to changes in our executive management. Two
executives left Allegheny Technologies in the 2000 fourth quarter. Both of these
executives were parties to employment and severance arrangements that obligated
Allegheny Technologies to make specific payments to them as a result of their
departure.

     The 1999 net restructuring and transformation charges of $5.6 million
include costs associated with adjusting employee benefit plans as a result of
the spin-offs which were partially offset by a $7.2 million reversal of
restructuring costs accrued in 1998 related to workforce reductions which were
implemented at less than expected costs.

     At December 31, 2001, substantially all cash expenditures related to the
2000 and 1999 restructuring and transformation charges had been paid.

  Gains on Sales of Assets and Other

     Gains on sales of assets and other includes pre-tax gains on the sale of
real estate, certain investments and other assets, which are primarily included
in other income on the statement of operations, as well as charges incurred in
connection with closed operations. These items resulted in net charges of $14.8
million, $4.4 million and $0.2 million in 2001, 2000 and 1999, respectively. In
2001, we recorded a pre-tax charge of $5.6 million to write-off its minority
interest in the e-Business site, MetalSpectrum, which terminated operations
during the 2001 second quarter. In 2000, we realized a gain of $11.0 million on
the sale of a minority interest in Gul Technologies Singapore, Ltd.

     Gains on sales of assets and other for 1999 does not include extraordinary
gains on sales of operations of $129.6 million. These extraordinary gains are
presented separately on the statement of operations.

  CORPORATE EXPENSES

     Corporate expenses were $25.5 million in 2001 compared to $30.6 million in
2000, and $38.9 million in 1999. The continued decline in corporate expenses is
due to cost controls and reductions in the number of corporate employees.

  INCOME TAXES

     Our effective income tax rate from continuing operations was (30.8)
percent, 36.5 percent and 36.3 percent in 2001, 2000 and 1999, respectively. Our
negative effective income tax rate for 2001 represents a tax benefit that will
be realized by a refund of income taxes paid in prior years. The effective tax
rate for 2001 declined compared to prior years primarily due to losses at
certain operations for which we did not receive a state tax benefit.

     At December 31, 2001, we had a state deferred tax asset resulting from net
operating loss tax carryforwards of $18.2 million. A valuation allowance of
$18.2 million was established for the full value of these operating loss
carryforwards since we have concluded that it is more likely than not that these
tax benefits would not be realized.

                                        24


     Allegheny Technologies has concluded that the remaining deferred tax assets
should be realized based upon its history of operating earnings, expectations of
future operating earnings, and potential tax planning strategies.

FINANCIAL CONDITION AND LIQUIDITY

     We believe that internally generated funds, current cash on hand and
borrowings from existing credit lines and its commercial paper program will be
adequate to meet foreseeable needs. However, our ability to continue to utilize
borrowings from existing credit lines and maintain our commercial paper program
may be negatively affected by changes in our credit rating based upon our
financial performance, and the credit ratings agencies' and credit market's
outlook for the industry and markets in which we participate, as well as failure
to maintain required financial ratios, and other factors beyond our control.

     We have no off-balance sheet financing relationships with special purpose
entities, structured finance entities, or any other unconsolidated entities.

  CASH FLOW AND WORKING CAPITAL

     During 2001, cash generated from operations of $122.8 million, net
borrowings of $37.6 million and net proceeds from asset sales of $18.5 million
were used to invest $104.2 million in capital equipment and business expansion,
primarily in the High Performance Metals segment, pay dividends of $64.2
million, repurchase common stock of $3.0 million and increase cash balances by
$7.5 million. Cash transactions plus cash on hand at the beginning of the year
resulted in an ending cash position of $33.7 million at December 31, 2001.

     Working capital decreased to $593.4 million at December 31, 2001 compared
to $609.3 million at the end of 2000. The current ratio increased to 2.8 in 2001
from 2.5 in 2000. The reduction in working capital was primarily due to a
decrease in inventory levels and accounts receivable, partially offset by
reductions in short-term debt, accrued liabilities and accounts payable.

     As part of managing the liquidity of the business, we focus on controlling
inventory, accounts receivable and accounts payable. In measuring performance in
controlling this managed working capital, we exclude the effects of the LIFO
inventory valuation reserves, excess and obsolete inventory reserves, and
reserves for uncollectible accounts receivable which, due to their nature, are
managed separately. During 2001, excluding the effects of operations sold,
managed working capital, which is defined as gross inventory plus accounts
receivable less accounts payable, declined by $127 million, or 14.9 percent, to
$728 million. For 2001, the decline in managed working capital resulted from a
$102 million decline in inventory and a $38 million decline in accounts
receivable, partially offset by lower accounts payable balances of $13 million.

     Capital expenditures for 2001 were $104.2 million and are expected to
approximate $50 million in 2002 for operational necessities and the completion
of certain capital projects initiated in 2001.

  DEBT

     At December 31, 2001, we had $582.2 million in total outstanding debt. Our
debt to capitalization ratio increased to 38.1 percent in 2001 from 34.4 percent
in 2000. Our net debt to total capitalization ratio increased to 36.7 percent in
2001 from 33.2 percent in 2000. These higher ratios resulted primarily from the
increase in debt levels and a reduction in stockholders' equity.

     In December 2001, we issued $300 million of 8.375% Notes due December 15,
2011 in a transaction exempt from registration pursuant to Rule 144A under the
Securities Act of 1933, as amended. We are required to file this registration
statement with the Securities and Exchange Commission in order to offer the
holders of the Notes the ability to exchange the outstanding Notes for new notes
with substantially identical terms, but which are registered under the
Securities Act. Interest on the Notes is payable semi-annually, on June 15 and
December 15, and is subject to adjustment under certain circumstances. These
Notes contain default provisions with respect to default for the following,
among other things: nonpayment of interest on the Notes for 30 days, default in
payment of principal when due, or failure to comply with any covenant. Any
violation of the default provision could result in the requirement to
immediately repay the borrowings.

     On December 21, 2001, we entered into a new credit agreement with a group
of banks that provides for borrowings of up to $325 million on a revolving
credit basis. This new credit agreement replaces a $500 million credit facility,
which was to expire in August 2002. The new credit agreement consists of a
short-term 364-day
                                        25



$130 million credit facility which expires in December 2002, and a $195 million
credit facility which expires in December 2006. As of April 30, 2002, no
borrowings were outstanding under these credit facilities. Interest is payable
based upon London Interbank Offered Rates (LIBOR) plus a spread, which is
dependent on our credit rating. We also have the option of using other
alternative interest rate bases. The agreement has various covenants that limit
our ability to dispose of assets and merge with another corporation. We are also
required to maintain a ratio of total consolidated indebtedness to total
capitalization of not more than 60 percent. At December 31, 2001, our total
consolidated indebtedness to total capitalization calculated in accordance with
the credit agreement, which includes certain standby letters of credit and
guarantees, was 40 percent. This covenant also has the effect of limiting the
total amount of dividend payments and share repurchases. Under this covenant,
approximately $312 million, or 33 percent, of our retained earnings, is
currently free of restrictions pertaining to cash dividends and share
repurchases. In addition, the credit agreement contains a covenant requiring the
maintenance of specified EBITDA. For 2002, we must have, on a quarterly basis
for the preceding twelve month period, EBITDA of at least 3.0 times gross
interest expense. For 2003 through the remaining life of the credit agreement,
we must have, on a quarterly basis for the preceding twelve month period, EBITDA
of at least 3.5 times gross interest expense. Our EBITDA coverage (calculated in
accordance with the credit agreement, which excludes non-cash charges) for the
twelve months ended December 31, 2001 was 5.3 times gross interest expense.
EBITDA is defined under the credit agreement in a manner that excludes non-cash
charges. The definition of EBITDA used in the section entitled "Selected
Consolidated Financial Data" is described in footnote 1 to the table in that
section and excludes both cash and non-cash charges.


     During the fourth quarter of 2000, we implemented a commercial paper
program designed to cost effectively enhance our access to credit markets. At
December 31, 2001, we had $70 million of commercial paper outstanding, which is
scheduled to mature in the first quarter of 2002. These commercial paper
borrowings are presented as long-term obligations due to our ability and intent
to refinance a portion or all of these obligations on a long-term basis. Our
intention is to continue to use the commercial paper program to fund its capital
needs in excess of cash flow generated from operations. However, our ability to
continue our commercial paper program is dependent upon maintaining our current
A2/P2 commercial paper credit rating, and on having a bank credit facility to
support the program.

     A summary of our required payments under financial instruments (excluding
accrued interest) and other commitments are presented below.

    international trade.

     Additionally, we use derivative contracts to hedge, in certain
circumstances, our exposure to fluctuations in the cost of energy, raw
materials, and the value of foreign currencies. As part of certain of these
contracts, we have agreed that the net value of the derivative instrument being
used as a hedge will become immediately payable, or receivable, if there is
deterioration in our credit rating to non-investment grade. At December 31,
2001, the net value of hedges that would become immediately payable in the event
of a downgrade in our credit to non-investment grade was less than $3 million,
after-tax.

                                        26


  RETIREMENT BENEFITS

     Our defined benefit pension plan remained overfunded with investments
exceeding liabilities by approximately $200 million at December 31, 2001.
However, the value of pension plan assets declined by approximately $376 million
during 2001 primarily due to the decline in the equity markets in 2001 and
payment of benefits. This decline in the value of pension assets along with
increased pension liabilities and higher projected retiree health care costs
will result in a net non-cash, pre-tax retirement benefit expense for 2002 of
approximately $24 million. This compares to non-cash pre-tax income of $53.1
million in 2001.

     Our defined benefit pension plan is fully funded with assets in excess of
the projected benefit obligation. Under current Internal Revenue Code (Section
420) provisions, certain amounts that we pay for retiree health care benefits
may be reimbursed annually from the excess pension plan assets. During the 2001
second quarter, we recovered $35.0 million under these provisions. While not
affecting reported operating profit, cash flow from operations increased by the
recovered amount. Our ability to be reimbursed for retiree medical costs in
future years is dependent upon the level of pension surplus, as computed under
regulations of the Internal Revenue Service, as of the beginning of each year.
The level of pension surplus (the value of pension assets less pension
obligations) changes constantly due to the volatility of pension asset
investments. Due to the decline in the U.S. equities market in 2001, the pension
overfunded status at the beginning of 2002 is below the threshold required to
fully reimburse us for retiree medical costs in 2002. This will negatively
impact the after-tax cash flow in 2002 by approximately $22 million. The ability
to resume full reimbursement to us for retiree health care costs beyond 2002
will depend upon the performance of the pension investments, and any changes in
the Internal Revenue Code and regulations pertaining to reimbursement of retiree
health care costs from pension surplus. Beginning in the second half of 2001, we
began funding certain retiree health care benefits for Allegheny Ludlum using
plan assets held in a Voluntary Employee Benefit Association (VEBA) trust. This
allows us to recover a portion of the retiree medical costs that were previously
funded from the pension surplus. We may continue to fund certain retiree medical
benefits utilizing the plan assets held in the VEBA if the value of these plan
assets exceeds $50 million.

     Accounting standards require a minimum pension liability be recorded if the
value of pension assets is less than the accumulated pension benefit obligation
(ABO) at the end of the year. Based upon the value of pension assets as of
December 31, 2001, we are not required to record such a minimum pension
liability. However, if the value of pension assets were to decline to a level
below the ABO, we would record a minimum pension liability and record a charge
to shareholders' equity for the value of the prepaid pension asset currently
recognized on the balance sheet, and the required minimum pension liability, net
of deferred taxes.

  OTHER

     On February 14, 2002, the Board of Directors declared a regular quarterly
dividend of $0.20 per share of common stock. The dividend was paid on March 12,
2002 to stockholders of record at the close of business on February 25, 2002. We
paid a quarterly dividend of $0.20 per share of common stock during each of the
2001 quarters. The future declaration and payment of dividends and the amount of
such dividends will depend upon our results of operations, financial condition,
cash requirements, future prospects, any limitations imposed by credit
agreements or senior securities, and other factors deemed relevant by the Board
of Directors.

     In October 1998, our Board of Directors authorized up to a total of 25
million shares of Allegheny Technologies common stock to be acquired under our
stock repurchase program from time-to-time in the open market or in negotiated
transactions. From the inception of the share repurchase program through
December 31, 2001, we repurchased 20.5 million shares at a cost of $531.5
million. We have not repurchased shares under the program since early 2001 and
do not expect to resume repurchases under the program in the foreseeable future.

CRITICAL ACCOUNTING POLICIES

     The accompanying consolidated financial statements have been prepared in
conformity with accounting principles generally accepted in the United States.
When more than one accounting principle, or the method of its application, is
generally accepted, management selects the principle or method that is
appropriate in our specific circumstances. Application of these accounting
principles requires Allegheny Technologies management to make estimates about
the future resolution of existing uncertainties; as a result, actual results
could differ from these

                                        27


estimates. In preparing these financial statements, management has made its best
estimates and judgments of the amounts and disclosures included in the financial
statements giving due regard to materiality.

  INVENTORIES

     At December 31, 2001, we had net inventory of $508.4 million. Inventories
are stated at the lower of cost (last-in, first-out (LIFO), first-in, first-out
(FIFO) and average cost methods) or market, less progress payments. Costs
include direct material, direct labor and applicable manufacturing and
engineering overhead, and other direct costs. Most of our inventory is valued
utilizing the LIFO costing methodology. Inventory of our non-U.S. operations are
valued using average cost or FIFO methods.

     We evaluate product lines on a quarterly basis to identify inventory values
that exceed estimated net realizable value. The calculation of a resulting
reserve, if any, is recognized as an expense in the period that the need for the
reserve is identified. At December 31, 2001, the amount of such reserves was
immaterial. It is our general policy to write-down to scrap value any inventory
that is identified as obsolete and any inventory that has aged or has not moved
in more than twelve months. In some instances this criterion is twenty-four
months.

  REVENUE RECOGNITION AND ACCOUNTS RECEIVABLE

     Revenue is recognized when title passes or as services are rendered. We
have no significant unusual sale arrangements with any of our customers.

     We market our products to a diverse customer base, principally throughout
the United States. Trade credit is extended based upon evaluations of each
customer's ability to perform its obligations, which are updated periodically.
Accounts receivable reserves are based upon an aging of accounts plus identified
specific accounts. Accounts receivable are presented net of a reserve for
doubtful accounts of $12.3 million at December 31, 2001 and $7.4 million at
December 31, 2000, which represented 4.3 percent and 2.2 percent, respectively,
of total gross accounts receivable. During 2001, in recognition of the decline
in the economy and reduced availability of credit, we recognized expense of
$10.1 million to increase the reserve for doubtful accounts and wrote-off $5.2
million of uncollectible accounts, which reduced the reserve.

  ASSET IMPAIRMENT

     We monitor the recoverability of the carrying value of our long-lived
assets. An impairment charge is recognized when the expected net undiscounted
future cash flows from an asset's use (including any proceeds from disposition)
are less than the asset's carrying value and the asset's carrying value exceeds
its fair value.

     At December 31, 2001, we had $188.4 million of goodwill on our balance
sheet. Of the total, $126.6 million related to the Flat-Rolled Products segment,
$51.5 million related to the High Performance Metals segment, and $10.3 million
related to the Industrial Products segment. For 2001 and prior years, we were
required to evaluate whether the goodwill presented on the balance sheet was
impaired based upon the undiscounted future cash flows of the operating company
for which the goodwill relates.

     In June 2001, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 142, Goodwill and Other
Intangible Assets ("SFAS 142"). Under SFAS 142, the test for goodwill impairment
changed and, commencing in 2002, goodwill is required to be reviewed annually,
or more frequently if impairment indicators arise. The new impairment test for
goodwill is a two step process. The first step is a comparison of the fair value
of the reporting unit with its carrying amount, including goodwill. If this step
reflects impairment, then the loss would be measured as the excess of recorded
goodwill over its implied fair value. Implied fair value is the excess of the
fair value of the reporting unit over the fair value of all recognized and
unrecognized assets and liabilities.

     We are currently evaluating whether the goodwill on the balance sheet at
December 31, 2001 is impaired at January 1, 2002. If goodwill is determined to
be impaired, we would record a non-cash after-tax charge for the amount of the
impairment. This initial impairment charge, if any, would be recorded as a
cumulative effect of a change in accounting principle in our results for the
quarter ended June 30, 2002.

CONTINGENCIES

     When it is probable that a liability has been incurred or an asset of ours
has been impaired, a loss is recognized assuming the amount of the loss can be
reasonably estimated.

                                        28


     We are subject to various domestic and international environmental laws and
regulations that govern the discharge of pollutants into the air or water, and
the management and disposal of hazardous substances, and which may require that
it investigate and remediate the effects of the release or disposal of materials
at sites associated with past and present operations, including sites at which
we have been identified as a potentially responsible party ("PRP") under the
Comprehensive Environmental Response, Compensation and Liability Act, commonly
known as Superfund, and comparable state laws. We could incur substantial
cleanup costs, fines and civil or criminal sanctions, third party property
damage or personal injury claims as a result of violations or liabilities under
these laws or non-compliance with environmental permits required at its
facilities. We are currently involved in the investigation and remediation of a
number of our current and former sites as well as third party sites under these
laws. Our reserves for environmental remediation totaled approximately $46.7
million at December 31, 2001. Based on currently available information,
management does not believe that future environmental costs in excess of those
accrued with respect to sites with which we have been identified are likely to
have a material adverse effect on our financial condition or liquidity. The
resolution in any reporting period of one or more of these matters could have a
material adverse effect on our results of operations for that period. In
addition, there can be no assurance that additional future developments,
administrative actions or liabilities relating to environmental matters will not
have a material adverse effect on our financial condition or results of
operation. With respect to proceedings brought under the federal Superfund laws,
or similar state statutes, we have been identified as a potentially responsible
party at approximately 31 of such sites, excluding those at which it believes it
has no future liability. Our involvement is very limited or de minimis at
approximately 13 of these sites, and the potential loss exposure with respect to
any of the remaining 18 individual sites is not considered to be material. We
are a party to various cost-sharing arrangements with other PRPs at the sites.
The terms of the cost-sharing arrangements are subject to non-disclosure
agreements as confidential information. Nevertheless, the cost-sharing
arrangements generally require all PRPs to post financial assurance of the
performance of the obligations or to pre-pay into an escrow or trust account
their share of anticipated site-related costs. In addition, the Federal
government, through various agencies, is a party to several such arrangements.

     Environmental liabilities are recorded when our liability is probable and
the costs are reasonably estimable, but generally not later than the completion
of the feasibility study or our recommendation of a remedy or commitment to an
appropriate plan of action. The accruals are reviewed periodically and, as
investigations and remediations proceed, adjustments are made as necessary.
Accruals for losses from environmental remediation obligations do not take into
account the effects of inflation, and anticipated expenditures are not
discounted to their present value. The accruals are not reduced by possible
recoveries from insurance carriers or other third parties, but do reflect
anticipated allocations among potentially responsible parties at federal
Superfund sites or similar state-managed sites after an assessment is made of
the likelihood that such parties will fulfill their obligations at such sites.
Our measurement of environmental liabilities is based on currently available
facts, present laws and regulations, and current technology. Such estimates take
into consideration our prior experience in site investigation and remediation,
the data concerning cleanup costs available from other companies and regulatory
authorities, and the professional judgment of our environmental experts in
consultation with outside environmental specialists, when necessary.

RETIREMENT BENEFITS

     We have defined benefit pension plans and defined contribution plans
covering substantially all of our employees. We have not made contributions to
the defined benefit pension plan in the past six years because the plan has
remained fully funded. We account for our defined benefit pension plans in
accordance with SFAS No. 87, "Employers' Accounting for Pensions", which
requires that amounts recognized in financial statements be determined on an
actuarial basis, rather than as contributions are made to the plan. A
significant element in determining our pension income (expense) in accordance
with SFAS No. 87 is the expected return on plan assets. We have assumed, based
upon the types of securities the plan assets are invested in and the long-term
historical returns of these investments, that the long-term expected return on
pension assets will be 9 percent. The assumed long-term rate of return on assets
is applied to the market value of plan assets at the end of the previous year.
This produces the expected return on plan assets that is included in annual
pension income (expense) for the current year. The cumulative difference between
this expected return and the actual return on plan assets is deferred and
amortized into pension income or expense over future periods. The expected
return on plan assets can vary

                                        29


significantly from year to year since the calculation is dependent on the market
value of plan assets as of the end of the preceding year. Accounting principles
generally accepted in the U.S. allow companies to calculate expected return on
pension assets using either an average of fair market values of pension assets
over a period not to exceed five years, which reduces the volatility in reported
pension income or expense, or their fair market value at the end of the previous
year. However, the Securities and Exchange Commission currently does not permit
companies to change from the fair market value at the end of the previous year
methodology to an averaging of fair market values of plan assets methodology. As
a result, our results of operations and those of other companies, including
companies with which we compete, may not be comparable due to these different
methodologies in calculating expected return on pension assets.

     At the end of each year, we determine the discount rate to be used to value
pension plan liabilities. In accordance with SFAS No. 87, the discount rate
reflects the current rate at which the pension liabilities could be effectively
settled at the end of the year. In estimating this rate, we assess the rates of
return on high quality, fixed-income investments. Changes in the discount rate,
as well as the net effect of other changes in actuarial assumptions and
experience, are deferred in accordance with SFAS No. 87.

     We also sponsor several defined benefit postretirement plans covering
certain hourly and salaried employees. These plans provide health care and life
insurance benefits for eligible employees. In certain plans, our contributions
towards premiums are capped based upon the cost as of a certain date, thereby
creating a defined contribution. We use actuarial assumptions, including the
discount rate and the expected trend in health care costs, to estimate the costs
and benefits obligations for the plans. The discount rate, which is determined
annually at the end of each year, is developed based upon rates of return on
high quality, fixed-income investments. At December 31, 2001, we determined this
rate to be 7 percent. Based upon cost increases quoted by our medical care
providers for 2002 and predictions of continued significant medical cost
inflation in future years, we raised our expected trend in health care costs.
The annual assumed rate of increase in the per capita cost of covered benefits
for health care plans is estimated at 11 percent in 2002 and is assumed to
decrease to 5 percent in the year 2009 and remain level thereafter. As a result
of this change in the expected trend of health care costs, our 2002 pre-tax
other postretirement benefits expense will increase by approximately $3 million
compared to the 2001 expense.

OUR BUSINESS

     Specialty materials play a significant role in our lives. We are a world
leader in the manufacture of high value and commodity specialty products. Our
high value products accounted for 71% of total sales in 2001 and our commodity
products accounted for 29% of total sales in 2001. Specialty materials are
produced in a variety of forms, including sheet, strip, foil, plate, slab,
ingot, billet, bar, rod, wire, coil, tubing, and shapes, and are selected for
use in environments that demand materials having exceptional hardness,
toughness, strength, resistance to heat, corrosion or abrasion, or a combination
of these characteristics. Common end uses of our products include jet engines,
air frames, electrical energy production and generation, automotive, chemical
processing, oil and gas, construction and mining, machine and cutting tools,
appliances and food equipment, transportation and medical equipment and
implants.

Flat-Rolled Products Segment

     We produce, convert and distribute stainless steel, nickel-based alloys and
superalloys, and titanium and titanium-based alloys, in sheet, strip, plate and
foil, and Precision Rolled Strip(R) products, as well as silicon electric steels
and tool steels. Our Flat-Rolled Products segment consists of Allegheny Ludlum,
Allegheny Rodney, Rome Metals and Allegheny Ludlum's 60% interest in the Chinese
joint venture company known as Shanghai STAL Precision Stainless Steel Company
Limited ("STAL"), which commenced commercial production in 2000. The remaining
40% interest in STAL is owned by the Baosteel Group, a state authorized
investment company whose equity securities are publicly traded in the People's
Republic of China.

     As compared with carbon steel, stainless steel and nickel-based alloys
contain elements such as chromium, nickel and molybdenum for strength and
corrosion and heat resistance; titanium and titanium-based alloys provide higher
strength-to-weight ratios and are corrosion-resistant; tool steel alloys, which
contain more carbon than stainless steel, include tungsten, molybdenum and other
metals to make them both hard and malleable; and electrical steel contains
silicon to minimize electrical energy loss when in use. We offer these
flat-rolled products in a broad selection of grades, sizes and finishes designed
to meet international specifications. Finishing capabilities include plasma arc
cutting, shearing, abrasive cutting, sawing and machining. We provide technical
support for material selection. Our wide array of alloys and product forms
provides customers with choices from which to select the optimum alloy for their
application.

                                        31


     Sheet. Stainless steel, nickel-based alloy and titanium alloy sheet
products are used in a wide variety of consumer and industrial applications such
as food preparation, appliance, automotive, aerospace and medical applications
that require cleanability, fabricability and corrosion resistance. Approximately
70% by volume of our sheet products are sold to service centers, which have
slitting, cutting or other processing facilities, with the remainder sold
directly to end-use customers.

     Strip. Stainless steel, nickel-based alloy and titanium alloy strip
products are used in a variety of consumer and industrial products and a wide
range of automotive components. We also offer very thin Precision Rolled
Strip(R) products which range from 0.015 inch to less than 0.0015 inch (0.38

steel, nickel-based alloys, titanium and titanium alloys, and carbon steel that
are used by customers to fabricate a variety of different products ranging from
automobile components to photographic, computer, building and construction and
consumer products. Approximately 49% by volume of our strip products are shipped
directly to end-use customers, with the remainder to service centers, including
our own distribution network for flat-rolled strip materials.

     Plate.  Stainless steel, nickel-based alloy and titanium alloy plate
products are primarily used in industrial equipment that requires cleanability
or corrosion-resistant capabilities such as pollution control scrubbers, food
processing equipment, pulp and paper equipment, chemical processing equipment,
power generation equipment and aerospace applications. We process and distribute
stainless steel and nickel alloy plate and titanium and titanium alloy plate
products in a wide variety of grades and gauges. Approximately 75% by volume of
our plate products are sold to service centers, with the remainder sold directly
to end-use customers.

     Silicon Electric Steel. Our grain-oriented silicon electrical steel
products are used generally in applications in which electrical conductivity and
magnetic properties are important. These products are sold directly to end-use
customers, including manufacturers of transformers and communications equipment.

High Performance Metals Segment

     Our High Performance Metals segment produces, converts and distributes a
wide range of high performance alloys, including nickel- and cobalt-based alloys
and superalloys, titanium and titanium-based alloys, exotic alloys such as
zirconium, hafnium, niobium, tantalum, and their related alloys, and other
specialty materials, primarily in slab, ingot, billet, bar, rod, wire, coil and
seamless tube forms, and zirconium chemicals. Our High Performance Metals
segment consists of Allvac, Allvac Ltd (U.K.) and Wah Chang.

     Nickel-, Cobalt- and Titanium-Based Alloys and Superalloys. Our nickel-,
iron-, cobalt- and titanium-based alloys and superalloys are engineered to
retain exceptional strength and corrosion resistance at temperatures through
2,000 degrees Fahrenheit (1,093 degrees Celsius) and are used in critical,
high-stress applications. These products are designed for the high performance
requirements of aerospace, oil and gas, power generation, chemical processing,
transportation, biomedical, marine and nuclear industries. We permanently idled
our high cost titanium sponge facility in the first half of 2001. We now
purchase titanium sponge in the open market.

     Exotic Alloys -- Zirconium, Hafnium, Niobium and Tantalum. We are a leading
U.S. producer of zirconium, a highly corrosion-resistant metal that is
transparent to neutrons. Zirconium is used for fuel tubes and structural parts
in nuclear power reactors and for corrosion-resistant chemical industry
applications, and is also used in the jewelry and personal hygiene industries.
Hafnium, derived as a by-product of zirconium, is principally used for control
rods in nuclear reactors due to its ability to absorb neutrons, and as an
alloying addition in aerospace applications. We also produce niobium, also known
as columbium, in various forms and alloys. The higher quality grades we produce
are used as an alloying addition in superalloys for jet engines and for
aerospace applications such as rocket and fuel nozzles. Niobium and related
alloys are used in applications requiring superconducting characteristics for
high-strength magnets, including in medical devices for body-scanning,
accelerators for high-energy physics, and fusion energy projects for the
generation of electricity. We also produce tantalum, one of the most
corrosion-resistant metals, which is used for medical implants, chemical process
equipment and aerospace engine components.

Industrial Segment

     The Industrial Products segment's principal business includes the
production of tungsten powder, tungsten heavy alloys, tungsten carbide materials
and carbide cutting tools. The segment also produces large grey and

                                        32


ductile iron castings and carbon alloy steel forgings. The companies in this
segment are Metalworking Products, Casting Service and Portland Forge.

     Cutting Tools and Tungsten Carbide Products. We produce a line of sintered
tungsten carbide products that approach diamond hardness for the metalworking,
mining, oil and gas, and other industries requiring tools with extra hardness.
Cemented carbide products, which may be coated or uncoated, are used as
super-hard cutters in the high-speed machining and cutting of steel, high
temperature alloys and other applications where hardness and wear resistance are
important. Technical developments related to ceramics, coatings and other
disciplines are incorporated in these products.

     We also produce tungsten for worldwide markets, starting with numerous and
varied tungsten-bearing raw materials and resulting in tungsten and tungsten
carbide powders. Previously used cemented carbide parts are also recycled into
tungsten carbide powder.

     Forgings and Castings. We forge carbon alloy steels into finished forms
that are used in a diverse number of industries. With the latest screw-type
forging presses, we produce carbon alloy steel forgings in sizes ranging from
one pound to more than 200 pounds.

     We also cast grey and ductile iron metals in sizes ranging from 1,000
pounds to 160,000 pounds and in forms ranging from diesel locomotive engine
blocks to housings and parts for power generation equipment, tools, and
automobiles.

CAPITAL INVESTMENTS

     The current 2002 capital expenditure plan is approximately $50 million for
operational necessities and for completion of capital programs which commenced
in 2001.

COMPETITION

     Markets for our products and services in each of our principal business
segments are highly competitive. We compete with many manufacturers which,
depending on the product involved, range from large diversified enterprises to
smaller companies specializing in particular products. Factors that affect our
competitive posture are the quality of our products, services and delivery
capabilities, our capabilities to produce a wide range of specialty materials in
various unique grades, alloys and product forms, our technology capabilities
including our research and development efforts, and our marketing strategies and
price.

     Our companies face competition from domestic and foreign competitors, a
number of which are government subsidized. In 1999, the United States imposed
antidumping and countervailing duties on dumped and subsidized imports of
stainless steel sheet and strip in coils and stainless steel plate in coils from
companies in ten foreign countries. Current administrative reviews by the U.S.
Commerce Department are revising the findings at lower duty rates. We continue
to monitor unfairly traded imports from foreign producers for appropriate
action.


     On March 5, 2002, President Bush announced a decision imposing tariffs on
certain steel imports resulting from his June 5, 2001 order for an investigation
by the U.S. International Trade Commission ("ITC") under Section 201 of the 1974
Trade Act ("Section 201") related to certain specialty steel products. Section
201 allows the President to restrict imports or impose tariffs on imports that
are seriously injuring a domestic industry. Specialty steel products under
investigation for the years 1996 through 2000 include stainless steel bar, rod
and wire, and tool steel. The ITC found that certain imported products were
seriously injuring the domestic industry and in December 2001 made its
recommendations to the President for consideration. The ITC did not recommend,
and our industry did not seek, that tariffs be imposed on products of the type
we produce other than certain tool steels that represent an immaterial portion
of our sales. Therefore, we believe that the ITC's decision has minimal impact
on our business because of limited applicability to our products.


RAW MATERIALS AND SUPPLIES

     Substantially all parts and materials required in the manufacture of our
products are available from more than one supplier and the sources and
availability of raw materials essential to its businesses are adequate.

     The principal materials used by us in the production of our specialty
materials are scrap (including nickel-, chromium-, titanium- and
molybdenum-bearing scrap), nickel, titanium sponge, zirconium sand and sponge,

                                        33


ferrochromium, ferrosilicon, molybdenum and molybdenum alloys, ammonium
paratungstate, manganese and manganese alloys, cobalt, niobium and other
alloying materials.

     Purchase prices of certain critical raw materials are volatile. As a
result, our operating results could be subject to significant fluctuation. For
example, since we generally use in excess of 40,000 tons of nickel each year, a
hypothetical change of $1.00 per pound in nickel prices would result in
increased costs of approximately $80 million.

     In addition, certain of these raw materials, such as nickel, cobalt,
ferrochromium and titanium sponge, can be acquired by us and our specialty
materials industry competitors, in large part, only from foreign sources. Some
of these foreign sources are located in countries that may be subject to
unstable political and economic conditions, which might disrupt supplies or
affect the price of these materials.

     We purchase our nickel requirements principally from producers in
Australia, Canada, Norway, Russia, and the Dominican Republic. Zirconium sponge
is purchased from a source in France, while zirconium sand is purchased from
both U.S. and Australian sources. Cobalt is purchased primarily from producers
in Canada. More than 80% of the world's reserves of ferrochromium are located in
South Africa, Zimbabwe, Albania, and Kazakhstan. We also purchase titanium
sponge from sources in Kazakhstan, Japan and Russia.

EXPORT SALES AND FOREIGN OPERATIONS

     International sales represented approximately 23%, 18%, and 20% of our
total sales in 2001, 2000, and 1999, respectively. These figures include export
sales by U.S. operations to customers in foreign countries, which accounted for
approximately 15%, 12%, and 13% of our total sales in each of 2001, 2000, and
1999, respectively. Our overseas sales, marketing and distribution efforts are
aided by international marketing offices or representatives located at various
locations throughout the world.

     For 2001, external sales in the United States and Canada represented 77%
and 3%, respectively, of total 2001 external sales. Within Europe, external
sales to the United Kingdom, France and Germany represented 5%, 4% and 4%,
respectively, of total external sales.

     Our Metalworking Products unit manufactures high precision threading,
milling, boring and drilling systems for the European market from locations in
the United Kingdom, Spain, France, Germany and Switzerland. Our Allvac Ltd unit
has manufacturing capabilities in the United Kingdom and has enhanced service to
customers by improving the sales and distribution network for our nickel-based
alloys, specialty steel and titanium in Europe. In 2000, the STAL joint venture
in the People's Republic of China began commercial production of Precision
Rolled Strip(R) products. This venture enables us to offer our Precision Rolled
Strip(R) products more effectively to markets in China and other Asian
countries.

BACKLOG, SEASONALITY AND CYCLICALITY

     Our backlog of confirmed orders was approximately $488.9 million at
December 31, 2001 and $559.5 million at December 31, 2000. It is anticipated
that approximately 90% of confirmed orders on hand at December 31, 2001 will be
fulfilled during the year ended December 31, 2002. Backlog of confirmed orders
of the Flat-Rolled Products segment was $105.2 million at December 31, 2001 and
$143.5 million at December 31, 2000. It is anticipated that approximately 100%
of the confirmed orders on hand at December 31, 2001 for this segment will be
fulfilled during the year ending December 31, 2002. Backlog of confirmed orders
of the High Performance Metals segment was $377.9 million at December 31, 2001
and $353.5 million at December 31, 2000. It is anticipated that approximately
86% of the confirmed orders on hand at December 31, 2001 for this segment will
be fulfilled during the year ending December 31, 2002.

     Generally, sales and operations of our businesses are not seasonal.
However, demand for products of our businesses are cyclical over longer periods
because specialty materials customers operate in cyclical industries and are
subject to changes in general economic conditions.

RESEARCH, DEVELOPMENT AND TECHNICAL SERVICES

     Our management believes that our research and development capabilities give
us an edge in developing new products and manufacturing processes that
contribute to the profitable growth potential of us on a long-term basis. We
conduct research and development at our various operating locations both for our
own account and, on a
                                        34


limited basis, for customers on a contract basis. Estimates of the components of
research and development for each of our segments for the years ended December
31, 2001, 2000, and 1999 included the following:

     With respect to the Flat-Rolled Products and High Performance Metals
segments, our research, development and technical service activities are closely
interrelated and are directed toward cost reduction, process improvement,
process control, quality assurance and control, system development, the
development of new manufacturing methods, the improvement of existing
manufacturing methods, the improvement of existing products, and the development
of new products.

     We own several hundred United States patents, many of which are also filed
under the patent laws of other nations. Although these patents, as well as our
numerous trademarks, technical information, license agreements, and other
intellectual property, have been and are expected to be of value, management
believes that the loss of any single such item or technically related group of
such items would not materially affect the conduct of our business.

ENVIRONMENTAL, HEALTH AND SAFETY MATTERS

     We are subject to various domestic and international environmental laws and
regulations that govern the discharge of pollutants into the air or water, and
the management and disposal of hazardous substances, and which may require that
we investigate and remediate the effects of the release or disposal of materials
at sites associated with past and present operations, including sites at which
we have been identified as a potentially responsible party ("PRP") under the
Comprehensive Environmental Response, Compensation and Liability Act; commonly
known as Superfund, and comparable state laws. We could incur substantial
cleanup costs, fines and civil or criminal sanctions, third party property
damage or personal injury claims as a result of violations or liabilities under
these laws or non-compliance with environmental permits required at our
facilities. We are currently involved in the investigation and remediation of a
number of current and former sites as well as third party locations sites under
these laws. Our reserves for environmental remediation totaled approximately
$46.7 million at December 31, 2001. Based on currently available information,
management does not believe that future environmental costs in excess of those
accrued with respect to sites with which we have been identified are likely to
have a material adverse effect on our financial condition or liquidity. The
resolution in any reporting period of one or more of these matters could have a
material adverse effect on our results of operations for that period. In
addition, there can be no assurance that additional future developments,
administrative actions or liabilities relating to environmental matters will not
have a material adverse effect on our financial condition or results of
operation.

     With respect to proceedings brought under the federal Superfund laws, or
similar state statutes, we have been identified as a PRP at approximately 31 of
such sites, excluding those at which we believe we have no future liability. Our
involvement is very limited or de minimis at approximately 13 of these sites,
and the potential loss exposure with respect to any of the remaining 18
individual sites is not considered to be material.

     We are a party to various cost-sharing arrangements with other PRPs at the
sites. The terms of the cost-sharing arrangements are subject to non-disclosure
agreements as confidential information. Nevertheless, the cost-sharing
arrangements generally require all PRPs to post financial assurance of the
performance of the obligations or to pre-pay into an escrow or trust account
their share of anticipated site-related costs. In addition, the Federal
government, through various agencies, is a party to several such arrangements.

                                        35


EMPLOYEES

     We have approximately 10,700 employees. A portion of our workforce is
covered by various collective bargaining agreements, principally with the United
Steelworkers of America ("USWA"), including: approximately 3,700 Allegheny
Ludlum production and maintenance employees covered by collective bargaining
agreements between Allegheny Ludlum and the USWA, which are effective through
June 2007; approximately 325 Oremet employees covered by a collective bargaining
agreement with the USWA, which are effective through June 2007; and
approximately 660 Wah Chang employees covered by a collective bargaining
agreement with the USWA, which is effective through March 31, 2008.

     Generally, agreements that expire may be terminated after notice by the
USWA. After termination, the USWA may authorize a strike. A strike by the
employees covered by one or more of the collective bargaining agreements could
materially adversely affect the Company's operating results. There can be no
assurance that we will succeed in concluding collective bargaining agreements
with the USWA or other unions to replace those that expire.

                               THE EXCHANGE OFFER

PURPOSE AND EFFECT

     We issued the old notes on December 18, 2001 in a private placement to a
limited number of qualified institutional buyers, as defined under the
Securities Act. In connection with this issuance, we entered into the indenture
and the registration rights agreement. These agreements require that we file a
registration statement under the Securities Act with respect to the registered
notes to be issued in the exchange offer and, upon the effectiveness of the
registration statement, offer to you the opportunity to exchange your old notes
for a like principal amount of registered notes. These registered notes will be
issued without a restrictive legend and, except as set forth below, may be
reoffered and resold by you without registration under the Securities Act. After
we complete the exchange offer, our obligations with respect to the registration
of the notes will terminate, except as provided in the last paragraph of this
section. A copy of the indenture relating to the notes and the registration
rights agreement have been filed as exhibits to the registration statement of
which this prospectus is a part.

     Based on an interpretation by the staff of the Commission set forth in
no-action letters issued to third parties, if you are not our "affiliate" within
the meaning of Rule 405 under the Securities Act or a broker-dealer referred to
in the next paragraph, we believe that registered notes to be issued to you in
the exchange offer may be offered for resale, resold and otherwise transferred
by you, without compliance with the registration and prospectus delivery
provisions of the Securities Act. This interpretation, however, is based on your
representation to us that:

          (1) the registered notes to be issued to you in the exchange offer are
     acquired in the ordinary course of your business;

          (2) you are not engaging in and do not intend to engage in a
     distribution of the registered notes to be issued to you in the exchange
     offer; and

          (3) you have no arrangement or understanding with any person to
     participate in the distribution of the registered notes to be issued to you
     in the exchange offer.

     If you tender your old notes in the exchange offer for the purpose of
participating in a distribution of the registered notes to be issued to you in
the exchange offer, you cannot rely on this interpretation by the staff of the
Commission. Under those circumstances, you must comply with the registration and
prospectus delivery requirements of the Securities Act in connection with a
secondary resale transaction. Each broker-dealer that receives registered notes
in the exchange offer for its own account in exchange for old notes that were
acquired by the broker-dealer as a result of market-making activities or other
trading activities, must acknowledge that it will deliver a prospectus meeting
the requirements of the Securities Act in connection with any resales of those
registered notes. See "Plan of Distribution."

     If you (i) will not, under applicable law, receive freely tradeable
registered notes in the exchange offer, (ii) are not eligible to participate in
the exchange offer, (iii) may not sell the registered notes to the public
without delivering a prospectus and this prospectus is not appropriate or
available for such resales, or (iv) are a broker-dealer that holds old notes
that are a part of an unsold allotment from the original sale of the old notes,
you can elect, by indicating on the letter of transmittal and providing certain
additional necessary information, to have

                                        39


your old notes registered in a "shelf" registration statement on an appropriate
form pursuant to Rule 415 under the Securities Act. If we are obligated to file
a shelf registration statement, we will be required to keep the shelf
registration statement effective until the earliest of (a) two years from the
date the old notes were originally issued or (b) the date on which all the notes
registered under the shelf registration statement are disposed in accordance
with the shelf registration statement. Other than as set forth in this
paragraph, you will not have the right to require us to register your old notes
under the Securities Act. See " -- Procedures for Tendering" below.

     We will, in the event a shelf registration statement is filed, among other
things, provide to each holder for whom the shelf registration statement was
filed copies of the prospectus which is a part of the shelf registration
statement, notify each of those holders when the shelf registration statement
has become effective and take certain other actions as are required to permit
unrestricted resales of the notes. A holder selling notes pursuant to the shelf
registration statement generally would be required to be named as a selling
security holder in the related prospectus and to deliver a prospectus to
purchasers, will be subject to certain of the civil liability provisions under
the Securities Act in connection with such sales and will be bound by the
provisions of the registration rights agreement which are applicable to that
holder (including certain indemnification obligations).

     Under the registration rights agreement we will pay additional cash
interest on the applicable notes, subject to certain exceptions:

     (1) if the exchange offer registration statement is not declared effective
         by the Commission on or prior to the 150th day after the date the notes
         were issued,

     (2) if the exchange offer is not consummated on or before the 180th day
         after the date the notes are issued,

     (3) if obligated to file the shelf registration statement, we fail to file
         the shelf registration statement with the Commission on or prior to the
         30th day after the filing obligation arises,

     (4) if obligated to file the shelf registration statement, the shelf
         registration statement is not declared effective on or prior to the
         90th day after the obligation to file the shelf registration statement
         arises, or

     (5) after the exchange offer registration statement or the shelf
         registration statement, as the case may be, is effective, that
         registration statement thereafter ceases to be effective or usable
         (subject to certain exceptions);

(each such event referred to in clauses (1) through (5) above, a "Registration
Default") from and including the date on such Registration Default shall occur
to but excluding the date on which all Registration Defaults have been cured.

     The rate of additional interest will be at the rate of 0.25% per annum for
the first 90-day period immediately following the occurrence of the Registration
Default regardless of the number of Registration Defaults (and the rate will
increase by an additional 0.25% per annum with respect to each subsequent 90-day
period), until all Registration Defaults have been cured, up to a maximum
additional interest rate of 1.00% per annum. We will pay the additional interest
on regular interest payment dates. The additional interest will be in addition
to any other interest payable from time to time with respect to the notes.

     All references in the indenture, in any context, to any payment of
principal, purchase prices in connection with a purchase of notes, and interest
or any other amount payable on or with respect to any of the notes, shall be
deemed to include payment of any additional cash interest pursuant to the
registration rights agreement.

CONSEQUENCES OF FAILURE TO EXCHANGE

     After we complete the exchange offer, if you have not tendered your old
notes, you will not have any further registration rights, except as set forth
above. Your old notes will continue to be subject to certain restrictions on
transfer. Therefore, the liquidity of the market for your old notes could be
adversely affected upon completion of the exchange offer if you do not
participate in the exchange offer.

TERMS OF THE EXCHANGE OFFER

     Upon the terms and subject to the conditions set forth in this prospectus
and in the letter of transmittal, we will accept any and all old notes validly
tendered and not withdrawn prior to 5:00 p.m., New York City time, on the
expiration date. We will issue $1,000 principal amount of registered notes in
exchange for each $1,000

                                        40


principal amount of old notes accepted in the exchange offer. You may tender
some or all of your old notes pursuant to the exchange offer. However, old notes
may be tendered only in integral multiples of $1,000 principal amount.

     The form and terms of the registered notes are substantially the same as
the form and terms of the old notes, except that the registered notes to be
issued in the exchange offer have been registered under the Securities Act and
will not bear legends restricting their transfer. The registered notes will be
issued pursuant to, and entitled to the benefits of, the indenture. The
indenture also governs the old notes. The registered notes and the old notes
will be deemed one issue of notes under the indenture.


     As of the date of this prospectus, $300.0 million in aggregate principal
amount of 8.375% notes due 2011 were outstanding. This prospectus, together with
the letter of transmittal, is being sent to all registered holders and to others
believed to have beneficial interests in the old notes. You do not have any
appraisal or dissenters' rights in connection with the exchange offer under the
General Corporation Law of the State of Delaware or the indenture. We intend to
conduct the exchange offer in accordance with the applicable requirements of the
Securities and Exchange Act of 1934 (the "Exchange Act") and the rules and
regulations of the Commission promulgated under the Exchange Act.


     We will be deemed to have accepted validly tendered outstanding notes when,
as, and if we have given oral or written notice of our acceptance to the
exchange agent. The exchange agent will act as our agent for the tendering
holders for the purpose of receiving the registered notes from us. If we do not
accept any tendered notes because of an invalid tender, the occurrence of
certain other events set forth in this prospectus or otherwise, we will return
certificates for any unaccepted old notes, without expense, to the tendering
holder as promptly as practicable after the expiration date.

     You will not be required to pay brokerage commissions or fees or, except as
set forth below under " -- Transfer Taxes," transfer taxes with respect to the
exchange of your old notes in the exchange offer. We will pay all charges and
expenses, other than certain applicable taxes, in connection with the exchange
offer. See " -- Fees and Expenses" below.

EXPIRATION DATE; AMENDMENTS

     The exchange offer will expire at 5:00 p.m., New York City time, on
          , 2002, unless we determine, in our sole discretion, to extend the
exchange offer, in which case, it will expire at the later date and time to
which it is extended. We do not intend to extend the exchange offer, although we
reserve the right to do so. If we extend the exchange offer, we will give oral
or written notice of the extension to the exchange agent and give each
registered holder notice by means of a press release or other public
announcement of any extension prior to 9:00 a.m., New York City time, on the
next business day after the scheduled expiration date.

     We also reserve the right, in our sole discretion,

          (1) to delay accepting any old notes or, if any of the conditions set
     forth below under " -- Conditions" have not been satisfied or waived, to
     terminate the exchange offer by giving oral or written notice of such delay
     or termination to the exchange agent, or

          (2) to amend the terms of the exchange offer in any manner by
     complying with Rule 14e-l(d) under the Exchange Act to the extent that rule
     applies.

     We acknowledge and undertake to comply with the provisions of Rule 14e-l(c)
under the Exchange Act, which requires us to pay the consideration offered, or
return the old notes surrendered for exchange, promptly after the termination or
withdrawal of the exchange offer. We will notify you as promptly as we can of
any extension, termination or amendment.

PROCEDURES FOR TENDERING

  Book-Entry Interests

     The old notes were issued as global securities in fully registered form
without interest coupons. Beneficial interests in the global securities, held by
direct or indirect participants in DTC, are shown on, and transfers of these

DTC with respect to its participants.
                                        41


     If you hold your old notes in the form of book-entry interests and you wish
to tender your old notes for exchange pursuant to the exchange offer, you must
transmit to the exchange agent on or prior to the expiration date either:

          (1) a written or facsimile copy of a properly completed and duly
     executed letter of transmittal, including all other documents required by
     such letter of transmittal, to the exchange agent at the address set forth
     on the cover page of the letter of transmittal; or

          (2) a computer-generated message transmitted by means of DTC's
     Automated Tender Offer Program system and received by the exchange agent
     and forming a part of a confirmation of book-entry transfer, in which you
     acknowledge and agree to be bound by the terms of the letter of
     transmittal.

     In addition, in order to deliver old notes held in the form of book-entry
interests:

          (1) a timely confirmation of book-entry transfer of such notes into
     the exchange agent's account at DTC pursuant to the procedure for
     book-entry transfers described below under " -- Book-Entry Transfer" must
     be received by the exchange agent prior to the expiration date; or

          (2) you must comply with the guaranteed delivery procedures described
     below.

     The method of delivery of old notes and the letter of transmittal and all
other required documents to the exchange agent is at your election and risk.
Instead of delivery by mail, we recommend that you use an overnight or hand
delivery service. In all cases, sufficient time should be allowed to assure
delivery to the exchange agent before the expiration date. You should not send
the letter of transmittal or old notes to us. You may request your broker,
dealer, commercial bank, trust company, or nominee to effect the above
transactions for you.

  Certificated Old Notes

     Only registered holders of certificated old notes may tender those notes in
the exchange offer. If your old notes are certificated notes and you wish to
tender those notes for exchange pursuant to the exchange offer, you must
transmit to the exchange agent on or prior to the expiration date, a written or
facsimile copy of a properly completed and duly executed letter of transmittal,
including all other required documents, to the address set forth below under
" -- Exchange Agent." In addition, in order to validly tender your certificated
old notes:

          (1) the certificates representing your old notes must be received by
     the exchange agent prior to the expiration date; or

          (2) you must comply with the guaranteed delivery procedures described
     below.

  Procedures Applicable to All Holders

     If you tender an old note and you do not withdraw the tender prior to the
expiration date, you will have made an agreement with us in accordance with the
terms and subject to the conditions set forth in this prospectus and in the
letter of transmittal.

     If your old notes are registered in the name of a broker, dealer,
commercial bank, trust company or other nominee and you wish to tender your
notes, you should contact the registered holder promptly and instruct the
registered holder to tender on your behalf. If you wish to tender on your own
behalf, you must, prior to completing and executing the letter of transmittal
and delivering your old notes, either make appropriate arrangements to register
ownership of the old notes in your name or obtain a properly completed bond
power from the registered holder. The transfer of registered ownership may take
considerable time.

     Signatures on a letter of transmittal or a notice of withdrawal must be
guaranteed by an eligible institution unless:

          (1) old notes tendered in the exchange offer are tendered either

             (A) by a registered holder who has not completed the box entitled
        "Special Registration Instructions" or "Special Delivery Instructions"
        on the letter of transmittal or

             (B) for the account of an eligible institution; and

          (2) the box entitled "Special Registration Instructions" on the letter
     of transmittal has not been completed.

                                        42


     If signatures on a letter of transmittal or a notice of withdrawal are
required to be guaranteed, the guarantee must be by a financial institution,
which includes most banks, savings and loan associations and brokerage houses,
that is a participant in the Securities Transfer Agents Medallion Program, the
New York Stock Exchange Medallion Program or the Stock Exchanges Medallion
Program.

     If the letter of transmittal is signed by a person other than you, your old
notes must be endorsed or accompanied by a properly completed bond power and
signed by you as your name appears on those old notes.

     If the letter of transmittal or any old notes or bond powers are signed by
trustees, executors, administrators, guardians, attorneys-in-fact, officers of
corporations, or others acting in a fiduciary or representative capacity, those
persons should so indicate when signing. Unless we waive this requirement, in
this instance you must submit with the letter of transmittal proper evidence
satisfactory to us of their authority to act on your behalf.

     We will determine, in our sole discretion, all questions regarding the
validity, form, eligibility, including time of receipt, acceptance and
withdrawal of tendered old notes. This determination will be final and binding.
We reserve the absolute right to reject any and all old notes not properly
tendered or any old notes our acceptance of which would, in the opinion of our
counsel, be unlawful. We also reserve the right to waive any defects,
irregularities or conditions of tender as to particular old notes. Our
interpretation of the terms and conditions of the exchange offer, including the
instructions in the letter of transmittal, will be final and binding on all
parties.

     You must cure any defects or irregularities in connection with tenders of
your old notes within the time period we will determine unless we waive that
defect or irregularity. Although we intend to notify you of defects or
irregularities with respect to your tender of old notes, neither we, the
exchange agent nor any other person will incur any liability for failure to give
this notification. Your tender will not be deemed to have been made and your
notes will be returned to you if:

          (1) you improperly tender your old notes;

          (2) you have not cured any defects or irregularities in your tender;
     and

          (3) we have not waived those defects, irregularities or improper
     tender.

In this event, the exchange agent will return your notes, unless otherwise
provided in the letter of transmittal, as soon as practicable following the
expiration of the exchange offer.

     In addition, we reserve the right in our sole discretion to:

          (1) purchase or make offers for, or offer registered notes for, any
     old notes that remain outstanding subsequent to the expiration of the
     exchange offer;

          (2) terminate the exchange offer; and

          (4) to the extent permitted by applicable law, purchase notes in the
     open market, in privately negotiated transactions or otherwise.

     The terms of any of these purchases or offers could differ from the terms
of the exchange offer.

     By tendering, you will represent to us that, among other things:

          (1) the registered notes to be acquired by you in the exchange offer
     are being acquired in the ordinary course of your business;

          (2) you are not engaging in and do not intend to engage in a
     distribution of the registered notes to be acquired by you in the exchange
     offer;

          (3) you do not have an arrangement or understanding with any person to
     participate in the distribution of the registered notes to be acquired by
     you in the exchange offer; and

          (4) you are not our "affiliate," as defined under Rule 405 of the
     Securities Act.

     In all cases, issuance of registered notes for old notes that are accepted
for exchange in the exchange offer will be made only after timely receipt by the
exchange agent of certificates for your old notes or a timely book-entry
confirmation of your old notes into the exchange agent's account at DTC, a
properly completed and duly executed letter of transmittal, or a
computer-generated message instead of the letter of transmittal, and all other
required documents. If any tendered old notes are not accepted for any reason
set forth in the terms and

                                        43


conditions of the exchange offer or if old notes are submitted for a greater
principal amount than you desire to exchange, the unaccepted or non-exchanged
old notes, or old notes in substitution therefor, will be returned without
expense to you. In addition, in the case of old notes tendered by book-entry
transfer into the exchange agent's account at DTC pursuant to the book-entry
transfer procedures described below, the non-exchanged old notes will be
credited to your account maintained with DTC, as promptly as practicable after
the expiration or termination of the exchange offer.

  Guaranteed Delivery Procedures

     If you desire to tender your old notes and your old notes are not
immediately available or one of the situations described in the immediately
preceding paragraph occurs, you may tender if:

          (1) you tender through an eligible financial institution;

          (2) on or prior to 5:00 p.m., New York City time, on the expiration
     date, the exchange agent receives from an eligible institution, a written
     or facsimile copy of a properly completed and duly executed letter of
     transmittal and notice of guaranteed delivery, substantially in the form
     provided by us; and

          (3) the certificates for all certificated old notes, in proper form
     for transfer, or a book-entry confirmation, and all other documents
     required by the letter of transmittal, are received by the exchange agent
     within three New York Stock Exchange trading days after the date of
     execution of the notice of guaranteed delivery.

     The notice of guaranteed delivery may be sent by facsimile transmission,
mail or hand delivery. The notice of guaranteed delivery must set forth:

          (1) your name and address;

          (2) the amount of old notes you are tendering; and

          (3) a statement that your tender is being made by the notice of
     guaranteed delivery and that you guarantee that within three New York Stock
     Exchange trading days after the execution of the notice of guaranteed
     delivery, the eligible institution will deliver the following documents to
     the exchange agent:

             (A) the certificates for all certificated old notes being tendered,
        in proper form for transfer or a book-entry confirmation of tender;

             (B) a written or facsimile copy of the letter of transmittal, or a
        book-entry confirmation instead of the letter of transmittal; and

             (C) any other documents required by the letter of transmittal.

BOOK-ENTRY TRANSFER

     The exchange agent will establish an account with respect to the book-entry
interests at DTC for purposes of the exchange offer promptly after the date of
this prospectus. You must deliver your book-entry interest by book-entry
transfer to the account maintained by the exchange agent at DTC. Any financial
institution that is a participant in DTC's systems may make book-entry delivery
of book-entry interests by causing DTC to transfer the book-entry interests into
the exchange agent's account at DTC in accordance with DTC's procedures for
transfer.

     If one of the following situations occur:

          (1) you cannot deliver a book-entry confirmation of book-entry
     delivery of your book-entry interests into the exchange agent's account at
     DTC; or

          (2) you cannot deliver all other documents required by the letter of
     transmittal to the exchange agent prior to the expiration date,

then you must tender your book-entry interests according to the guaranteed
delivery procedures discussed above.

WITHDRAWAL RIGHTS

     You may withdraw tenders of your old notes at any time prior to 5:00 p.m.,
New York City time, on the expiration date.

                                        44


     For your withdrawal to be effective, the exchange agent must receive a
written or facsimile transmission notice of withdrawal at its address set forth
below under " -- Exchange Agent" prior to 5:00 p.m., New York City time, on the
expiration date.

     The notice of withdrawal must:

          (1) state your name;

          (2) identify the specific old notes to be withdrawn, including the
     certificate number or numbers and the principal amount of withdrawn notes;

          (3) be signed by you in the same manner as you signed the letter of
     transmittal when you tendered your old notes, including any required
     signature guarantees or be accompanied by documents of transfer sufficient
     for the exchange agent to register the transfer of the old notes into your
     name; and

          (4) specify the name in which the old notes are to be registered, if
     different from yours.

     We will determine all questions regarding the validity, form and
eligibility, including time of receipt, of withdrawal notices. Our determination
will be final and binding on all parties. Any old notes withdrawn will be deemed
not to have been validly tendered for exchange for purposes of the exchange
offer. Any old notes which have been tendered for exchange but which are not
exchanged for any reason will be returned to you without cost as soon as
practicable after withdrawal, rejection of tender or termination of the exchange
offer. Properly withdrawn old notes may be retendered by following one of the
procedures described under " -- Procedures for Tendering" above at any time on
or prior to 5:00 p.m., New York City time, on the expiration date.

CONDITIONS

     Notwithstanding any other provision of the exchange offer and subject to
our obligations under the registration rights agreement, we will not be required
to accept for exchange, or to issue registered notes in exchange for, any old
notes and may terminate or amend the exchange offer, if at any time before the
acceptance of any old notes for exchange any of the following events occur:

          (1) any injunction, order or decree has been issued by any court or
     any governmental agency that would prohibit, prevent or otherwise
     materially impair our ability to proceed with the exchange offer; or

          (2) the exchange offer violates any applicable law or any applicable
     interpretation of the staff of the Commission.

     These conditions are for our sole benefit and we may assert them regardless
of the circumstances giving rise to them, subject to applicable law. We also may
waive in whole or in part at any time and from time to time any particular
condition in our sole discretion. If we waive a condition, we may be required in
order to comply with applicable securities laws to extend the expiration date of
the exchange offer. Our failure at any time to exercise any of the foregoing
rights will not be deemed a waiver of these rights and these rights will be
deemed ongoing rights which may be asserted at any time and from time to time.

     In addition, we will not accept for exchange any old notes tendered, and no
registered notes will be issued in exchange for any of those old notes, if at
the time the old notes are tendered any stop order is threatened by the
Commission or in effect with respect to the registration statement of which this
prospectus is a part or the qualification of the indenture under the Trust
Indenture Act of 1939.

     The exchange offer is not conditioned on any minimum principal amount of
old notes being tendered for exchange.

FEES AND EXPENSES

     We will not pay brokers, dealers, or others soliciting acceptances of the
exchange offer. The principal solicitation is being made by mail. Additional
solicitations, however, may be made in person or by telephone by our officers
and employees.

     We will pay the estimated cash expenses to be incurred in connection with
the exchange offer. These are estimated in the aggregate to be approximately
$          which includes fees and expenses of the exchange agent, accounting,
legal, printing and related fees and expenses.

TRANSFER TAXES

     You will not be obligated to pay any transfer taxes in connection with a
tender of your old notes for exchange unless you instruct us to register

accepted in the exchange offer be returned to, a person other than the
registered tendering holder, in which event the registered tendering holder will
be responsible for the payment of any applicable transfer tax.

consummation of the exchange offer. We will amortize the expense of the exchange
offer over the term of the registered notes under generally accepted accounting
principles.

                                        46


                      DESCRIPTION OF THE REGISTERED NOTES

     The following description is only a summary of certain provisions of the
indenture and the registered notes that we consider material. You can receive a
copy of the indenture upon request to us at the address set forth under "Where
You Can Find More Information."

GENERAL

     We will issue the registered notes under an indenture between us and The
Bank of New York, as trustee. The terms of the notes include those stated in the
indenture and those made part of the indenture by reference to the Trust
Indenture Act of 1939.

     The registered notes will be issued in an initial aggregate principal
amount of $300,000,000. The registered notes will mature on December 15, 2011.
Interest on the registered notes will accrue at the rate of 8.375% per annum.

     We will pay interest on the registered notes semi-annually in arrears on
June 15 and December 15 of each year, commencing June 15, 2002, to the holders
of record of the notes on the immediately preceding June 1 and December 1.

     The registered notes will be our senior unsecured obligations and will rank
equal in right of payment with all of our existing and future unsecured and
unsubordinated debt. The notes will be effectively subordinated in right of
payment to any of our existing and future senior secured indebtedness to the
extent of the assets securing that indebtedness.

     We may from time to time, without notice to or consent of the holders,
issue additional notes of the same tenor, coupon and other terms as the notes,
so that such notes and the notes offered hereby shall form a single series.

     The registered notes will be issued only in fully registered form, without
coupons, in denominations of $1,000 and any integral multiple of $1,000.

OPTIONAL REDEMPTION

     We may redeem the notes, in whole or in part, at any time at a redemption
price equal to the greater of:

     - 100% of the principal amount of the notes, plus accrued and unpaid
       interest thereon to the date of redemption; or

     - the sum of the remaining scheduled payments of principal of and interest
       on the notes being redeemed (not including any portion of the payments of
       interest accrued as of the date of redemption), discounted to its present
       value as of the date of redemption on a semi-annual basis (assuming a
       360-day year consisting of twelve 30-day months) at the Adjusted Treasury
       Rate, as determined by the Quotation Agent, plus 25 basis points, plus
       accrued and unpaid interest on the principal amount being redeemed to the
       date of redemption.


     Our decision whether to redeem the notes will be based on a number of
factors, including available cash and other financial resources, then-prevailing
capital market and general economic conditions and other factors deemed relevant
by our Board of Directors taking into consideration any redemption premium that
would be payable described above. Taking into account these factors, we could
determine to redeem the notes if we believed it was financially beneficial for
us to do so.



     If less than all of the notes are to be redeemed at any time, selection of
the notes for redemption will be made by the trustee in compliance with the
requirements of the principal national securities exchange, if any, on which the
notes are listed or, if the notes are not then listed on a national securities
exchange, on a pro rata basis, by lot or by such method as the trustee shall
deem fair and appropriate. No notes of a principal amount of $1,000 or less will
be redeemed in part.


     "Adjusted Treasury Rate" means, with respect to any redemption date, the
rate per annum equal to the semi-annual equivalent yield to maturity of the
Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue
(expressed as a percentage of its principal amount) equal to the Comparable
Treasury Price for such redemption date.

                                        47


     "Comparable Treasury Issue" means the United States Treasury security
selected by the Quotation Agent as having a maturity comparable to the remaining
term of the notes to be redeemed that would be utilized, at the time of
selection and in accordance with customary financial practice, in pricing new
issues of corporate debt securities of comparable maturity to the remaining term
of such notes.

     "Comparable Treasury Price" means, with respect to any redemption date, (i)
the average of the Reference Treasury Dealer Quotations for such redemption
date, after excluding the highest and lowest such Reference Treasury Dealer
Quotations, or (ii) if the trustee obtains fewer than three such Reference
Treasury Dealer Quotations, the average of all such quotations.

     "Quotation Agent" means the Reference Treasury Dealer appointed by us.

     "Reference Treasury Dealer" means (i) each of J.P. Morgan Securities Inc.
and Banc of America Securities LLC and their respective successors and three
other nationally recognized investment banking firms that are Primary Treasury
Dealers specified from time to time by us. However, if the foregoing shall cease
to be a primary U.S. Government securities dealer in New York City (a "Primary
Treasury Dealer"), we shall substitute therefor another Primary Treasury Dealer;
and (ii) any other Primary Treasury Dealer selected by us.

     "Reference Treasury Dealer Quotations" means, with respect to each
Reference Treasury Dealer and any redemption date, the average, as determined by
us, of the bid and asked prices for the Comparable Treasury Issue (expressed in
each case as a percentage of its principal amount) quoted in writing to the
trustee by such Reference Treasury Dealer at 5:00 p.m., New York City time, on
the third business day preceding such redemption date.

     Notice of any redemption will be mailed at least 30 days but not more than
60 days before the redemption date to each holder of the notes to be redeemed.
Unless we default in payment of the redemption price, on and after the
redemption date, interest will cease to accrue on the notes or portions thereof
called for redemption.

CERTAIN COVENANTS

          The indenture contains certain covenants, including, among others, the
     following;

  Limitations on Liens

     The indenture provides that we will not, and will not permit any of our
Domestic Subsidiaries, directly or indirectly, to issue, assume or guarantee any
Debt if that Debt is secured by any Lien upon any Principal Property (or portion
thereof) of ours or of any Domestic Subsidiary or any shares of stock or
indebtedness of any Domestic Subsidiary, whether owned at the date of the
indenture or thereafter acquired, without effectively securing the notes equally
and ratably with that Debt, so long as such Debt is so secured. The foregoing
restriction does not apply to:

     (1) Liens on any property acquired, constructed or improved by us or any
         Domestic Subsidiary after December 18, 2001, which are created or
         assumed contemporaneously with or within three years after its
         acquisition, or completion of construction or improvement (or within
         six months thereafter pursuant to a firm commitment for financing
         arrangements entered into within that three-year period) to secure or
         provide for the payment of the purchase price or cost thereof, or Liens
         existing on any property at the time of its acquisition;

     (2) Liens existing on any property, shares of stock or indebtedness
         acquired from a Person merged with or into us or a Domestic Subsidiary
         after December 18, 2001;

     (3) with respect to any corporation that becomes a Domestic Subsidiary
         after December 18, 2001, Liens on property of, or shares of stock or
         indebtedness issued by, any such corporation existing at the time it
         becomes a Domestic Subsidiary and not incurred in connection with or in
         anticipation of such corporation becoming a Domestic Subsidiary;

     (4) Liens to secure Debt of a Domestic Subsidiary owed to us or Debt of one
         of our Domestic Subsidiaries owed to another Domestic Subsidiary;

     (5) Liens in favor of governmental bodies to secure partial, progress,
         advance or other payments pursuant to any contract or statute;

     (6) any Lien existing on December 18, 2001; or

                                        48


     (7) Liens for the sole purpose of extending, renewing or replacing Debt, in
         whole or in part, secured by any Lien referred to in the foregoing
         clauses (1) to (6), inclusive, provided, however, that the principal
         amount of Debt secured by that Lien shall not exceed the principal
         amount of Debt so secured at the time of such extension, renewal or
         replacement, and that such extension, renewal or replacement shall be
         limited to the property that secured the Lien so extended, renewed or
         replaced (plus improvements on such property).

     The limitation on liens shall not apply to the issuance, assumption or
guarantee by us or any Domestic Subsidiary of Debt secured by a Lien which would
otherwise be subject to the foregoing restrictions up to an aggregate amount
which, together with all other Debt of ours and our Domestic Subsidiaries
secured by Liens (not including Liens permitted under the foregoing exceptions)
and the Attributable Debt with respect to Sale and Leaseback Transactions
existing at that time (other than Sale and Leaseback Transactions in which the
property involved would have been permitted to be subject to a Lien under clause
(1) above) does not exceed 10% of Consolidated Net Tangible Assets.

  Limitations on Sale and Leaseback Transactions

     We and our Domestic Subsidiaries are prohibited from entering into Sale and
Leaseback Transactions unless:

          (a) We or such Domestic Subsidiary would be entitled to incur Debt
     secured by a Lien on the Principal Property to be leased without equally
     and ratably securing the notes, pursuant to clauses (1)-(7) under
     "Limitations on Liens"; or the Attributable Debt with respect thereto would
     be an amount permitted under the last sentence under "Limitations on
     Liens"; or

          (b) We or such Domestic Subsidiary shall, within 180 days of the
     effective date of any such arrangement apply an amount equal to the
     proceeds from such Sale and Leaseback Transaction to the payment or other
     retirement of Debt that ranks senior to or equal with the notes (other
     than, in either case, Debt owed by us or any Subsidiary); or to the
     purchase of other Principal Property.

  Limitation on Guarantees

     We and our Domestic Subsidiaries are prohibited from entering into any
agreement pursuant to which any such Domestic Subsidiary guarantees the payment
of Debt incurred by us without providing that the notes be equally and ratably
guaranteed by such Domestic Subsidiary.

MERGER, CONSOLIDATION, OR SALE OR CONVEYANCE OF ASSETS

     We may not consolidate or merge with or into any other Person or sell,
assign, convey or transfer or otherwise dispose of all or substantially all of
our properties and assets to any Person, unless:

          (1) the successor Person shall be a Person (if not Allegheny
     Technologies) organized and existing under the laws of the United States,
     any State thereof or the District of Columbia, and shall expressly assume,
     by a supplemental indenture satisfactory to the trustee, the due and
     punctual payment of the principal of, premium on, and interest on the notes
     and the performance of every covenant in the indenture on our part;

          (2) immediately after giving effect to such transaction, no Event of
     Default, and no event which, after notice or lapse of time or both, would
     become an Event of Default, shall have occurred and be continuing; and

          (3) we shall have delivered to the trustee an officer's certificate
     and an opinion of counsel, each stating that the consolidation, merger,
     conveyance or transfer and the supplemental indenture comply with clauses
     (1) and (2) above.

     In the case of any consolidation, merger, conveyance or transfer, the
successor Person will succeed to and be substituted for Allegheny Technologies
as obligor on the notes, with the same effect as if it had been named in the
indenture as Allegheny Technologies.

                                        49


EVENTS OF DEFAULT AND REMEDIES

     Each of the following is an Event of Default with respect to the registered
notes:

          (1) default for 30 days in the payment of interest on the notes;

          (2) default in payment when due of principal of, or premium, if any,
     on the notes;

          (3) our failure to comply with any covenant or warranty in the
     indenture for a period of 90 days after notice is provided to us by the
     trustee or the holders of at least 25% in aggregate principal amount of the
     then outstanding notes; and

          (4) certain events of bankruptcy, insolvency and reorganization with
     respect to us.

     If an Event of Default occurs (other than an Event of Default of the type
described in clause (4) above) and is continuing, the trustee or the holders of
at least 25% in aggregate principal amount of the outstanding notes may declare
the principal of, and accrued but unpaid interest on, all the notes to be due
and payable immediately, and if an Event of Default of the type described in
clause (4) above occurs, the principal of, and accrued but unpaid interest on
the notes will become immediately due and payable; however, in the case of Event
of Default specified in clause (3) upon certain conditions such declarations may
be annulled and past defaults may be waived (except for defaults in the payment
of principal, any premium on, or any interest on the notes) by the holders of a
majority of the aggregate principal amount of notes then outstanding.

     Subject to certain limitations, the holders of a majority in principal
amount of the outstanding notes are given the right to direct the time, method
and place of conducting any proceeding for any remedy available to the trustee
or of exercising any trust or power conferred on the trustee. The trustee,
however, may, upon the advice of counsel refuse to follow any direction that
conflicts with the law or the indenture or that the trustee determines is unduly
prejudicial to the holders or that would involve the trustee in personal
liability.

     The indenture will provide that if an uncured default is known to the
trustee, the trustee must give to each holder notice of the default within 90
days after it occurs. However, in the case of default in the payment of
principal of, any premium on, or interest on any note, the trustee may withhold
notice if it in good faith determines that withholding notice is in the interest
of the holders. In addition, we are required to deliver to the trustee, within
120 days after the end of each fiscal year, a certificate indicating that to the
best of the knowledge of the signatory we are not in default in the performance
and observance of the terms of the indenture or, if we are in default,
specifying such default.

MODIFICATIONS

     The indenture or the rights of the holders may be modified by us and the
trustee with the consent of at least a majority of the aggregate principal
amount of the outstanding notes. However, no such modification shall, without
the consent of each holder affected thereby:

     - change the stated maturity of the principal of, or any premium on, or any
       installment of interest on, any notes;

     - reduce the principal amount of, premium, if any, or interest on any
       notes;

     - reduce the amount payable upon the redemption of the note or change the
       time at which any note may be redeemed;

     - change the method or date of computing the amount of principal of or
       interest on the notes;

     - change the place or currency of payment of principal of or interest on
       the notes;

     - impair the right to institute suit for the enforcement of any payment on
       or after the stated maturity date or redemption date;

     - reduce the percentage in principal amount of the outstanding notes, the
       consent of whose holders is necessary for waiver of compliance with
       certain provisions of the indenture or for the waiver of certain
       defaults; or

     - modify any of the provisions of certain sections of the indenture
       including the provisions summarized by this paragraph.

                                        50


DEFEASANCE AND DISCHARGE

     The indenture provides that we will be Discharged from all obligations in
respect of the notes (except for, among other things, certain obligations to
register the transfer or exchange of the notes, replace stolen, lost or
mutilated notes, maintain paying agencies and old moneys or payment in trust) if
we have irrevocably deposited with the trustee, in trust for the benefit of the
holders of the notes, cash in U.S. dollars, non-callable Governmental
Securities, or a combination thereof, in such amounts as will be sufficient, in
the opinion of a nationally recognized firm of independent public accountants,
to pay the principal of, premium, if any, and interest and additional interest,
if any, on the outstanding notes on the stated maturity date or any redemption
date selected by us.

     The defeasance and discharge will become effective after we, among other
things, have delivered to the trustee an opinion of counsel confirming that the
deposit and related defeasance will not cause the holders of the notes to
recognize gain or loss for federal income tax purposes, or a copy of a ruling or
other formal statement or action to such effect received from or published by
the Internal Revenue Service.

DEFEASANCE OF CERTAIN OBLIGATIONS

     The indenture provides that we may at our option omit to comply with the
restrictive covenants of the indenture described above under "Certain Covenants"
if we have irrevocably deposited with the trustee, in trust for the benefit of
the holders of the notes, cash in U.S. dollars, non-callable Governmental
Securities, or a combination thereof, in such amounts as will be sufficient, in
the opinion of a nationally recognized firm of independent public accountants,
to pay the principal of, premium, if any, and interest and additional interest,
if any, on the outstanding notes on the stated maturity date or any redemption
date selected by us.

     Despite such deposit and covenant defeasance, our primary liability to pay
all outstanding notes shall survive until the payment of all principal thereof
and interest due thereon.

CONCERNING THE TRUSTEE

     The Bank of New York is the trustee under the indenture and is an affiliate
of BNY Capital Markets, Inc., one of the initial purchasers in the original
private placement of the old notes.

     The indenture provides that if an Event of Default occurs (and is not
cured), the trustee will be required, in the exercise of its power, to use the
degree of care of a prudent person in the conduct of its own affairs. The
trustee will be under no obligation to expend or risk its own funds or otherwise
incur any financial liability in the performance of any of its duties under the
indenture unless it has reasonable grounds for believing that repayment of such
funds or indemnity satisfactory to it against such risk or liability is assured
to it.

CERTAIN DEFINITIONS

     "Attributable Debt" in respect of a Sale and Leaseback Transaction means,
as of any particular time, the present value (discounted at the rate of interest

relating to the notes (and the trustee, at our expense, shall execute proper
instruments acknowledging the same), except (A) rights of registration of
transfer and exchange, and our right of optional redemption, if any; (B)
substitution of mutilated, defaced, destroyed, lost or stolen notes; (C) rights

     "Person" means an individual, corporation, partnership, joint venture,

real property, plant and equipment of which (as shown, without deduction of any
depreciation reserves, on the books of the owner or owners) is not less than two
percent of Consolidated Net Tangible Assets except (A) any such plant or
facility which our Board of Directors determines is not of material importance
to the total business conducted, or assets owned, by the Company and its
Domestic Subsidiaries as an entirety, or (B) any portion of any such plant or
facility which our Board of Directors determines not to be of material
importance to the use or operation thereof.

     "Sale and Leaseback Transaction" means any arrangement with any Person
providing for the leasing to the Company or any Domestic Subsidiary of any
Principal Property or portion thereof (except for temporary leases for a term,
including any renewal thereof, of not more than 36 months and except for leases

Property (or portion thereof) has been or is to be sold or transferred by the
Company or such Domestic Subsidiary to such Person.

     "Subsidiary" means with respect to any Person, any corporation, association

FORM OF REGISTERED NOTES

     The certificates representing the registered notes will be issued in fully
registered form, without coupons. Except as described in the next paragraph, the
registered notes will be deposited with, or on behalf of, DTC, and registered in
the name of Cede & Co., as DTC's nominee, in the form of a global note. Holders
of the registered notes will own book-entry interests in the global note
evidenced by records maintained by DTC.

     Book-entry interests may be exchanged for certificated notes of like tenor
and equal aggregate principal amount, if

          (1) DTC notifies us that it is unwilling or unable to continue as
     depositary or we determine that DTC is unable to continue as depositary and
     we fail to appoint a successor depositary within 90 days,

          (2) we provide for the exchange pursuant to the terms of the
     indenture, or

          (3) we determine that the book-entry interests will no longer be
     represented by global notes and we execute and deliver to the Trustee
     instructions to that effect.

     As of the date of this prospectus, no certificated notes are issued and
outstanding.

                   MATERIAL FEDERAL INCOME TAX CONSIDERATIONS

     The following is a summary of the material U.S. federal income tax
considerations relating to the exchange of old notes for registered notes in the
exchange offer. It does not contain a complete analysis of all the potential tax
considerations relating to the exchange. This summary is limited to holders of
old notes who hold the old
                                        52


notes as "capital assets" (in general, assets held for investment). Special
situations, such as the following, are not addressed:

     - tax consequences to holders who may be subject to special tax treatment,
       such as tax-exempt entities, dealers in securities or currencies, banks,
       other financial institutions, insurance companies, regulated investment
       companies, traders in securities that elect to use a mark-to-market
       method of accounting for their securities holdings or corporations that
       accumulate earnings to avoid U.S. federal income tax;

     - tax consequences to persons holding notes as part of a hedging,
       integrated, constructive sale or conversion transaction or a straddle or
       other risk reduction transaction;

     - tax consequences to holders whose "functional currency" is not the U.S.
       dollar;

     - tax consequences to persons who hold notes through a partnership or
       similar pass-through entity;

     - U.S. federal gift tax, estate tax (except as to non-United States
       holders) or alternative minimum tax consequences, if any; or

     - any state, local or foreign tax consequences.

     The discussion below is based upon the provisions of the Internal Revenue
Code of 1986, as amended, existing and proposed Treasury regulations promulgated
thereunder, and rulings, judicial decisions and administrative interpretations
thereunder, as of the date hereof. Those authorities may be changed, perhaps
retroactively, so as to result in U.S. federal income tax consequences different
from those discussed below.

CONSEQUENCES OF TENDERING NOTES

     The exchange of your old notes for registered notes in the exchange offer
will not constitute an exchange for federal income tax purposes. Accordingly,
the exchange offer will have no federal income tax consequences to you if you
exchange your old notes for registered notes. For example, there will be no
change in your tax basis and your holding period should carry over to the
registered notes. In addition, the federal income tax consequences of holding
and disposing of your registered notes will be the same as those applicable to
your old notes.

     THE PRECEDING DISCUSSION OF CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS
OF THE EXCHANGE OFFER IS FOR GENERAL INFORMATION ONLY AND IS NOT TAX ADVICE.
ACCORDINGLY, EACH INVESTOR SHOULD CONSULT ITS OWN TAX ADVISOR AS TO PARTICULAR
TAX CONSEQUENCES TO IT OF EXCHANGING OLD NOTES FOR REGISTERED NOTES, INCLUDING
THE APPLICABILITY AND EFFECT OF ANY STATE, LOCAL OR FOREIGN TAX LAWS, AND OF ANY
PROPOSED CHANGES IN APPLICABLE LAWS.

                              PLAN OF DISTRIBUTION

     Each broker-dealer that receives registered notes in the exchange offer for
its own account must acknowledge that it will deliver a prospectus meeting the
requirements of the Securities Act in connection with any resales of such notes.
We reserve the right in our sole discretion to purchase or make offers for, or
to offer registered notes for, any old notes that remain outstanding subsequent
to the expiration of the exchange offer pursuant to this prospectus or otherwise
and, to the extent permitted by applicable law, purchase old notes in the open
market, in privately negotiated transactions or otherwise. This prospectus, as
it may be amended or supplemented from time to time, may be used by all persons
subject to the prospectus delivery requirements of the Securities Act, including
broker-dealers in connection with resales of registered notes received in the
exchange offer, where such notes were acquired as a result of market-making
activities or other trading activities and may be used by us to purchase any
notes outstanding after expiration of the exchange offer. We have agreed that,
for a period of 180 days after the expiration of the exchange offer, we will
make this prospectus, as amended or supplemented, available to any broker-dealer
for use in connection with any such resale.

     We will not receive any proceeds from any sale of registered notes by
broker-dealers. Notes received by broker-dealers in the exchange offer for their
own account may be sold from time to time in one or more transactions in the
over-the counter market, in negotiated transactions, through the writing of
options on the registered notes or a combination of such methods of resale, at
market prices prevailing at the time of resale, at prices related to such
prevailing market prices or negotiated prices. Any such resale may be made
directly to

                                        53


purchasers or to or through brokers or dealers who may receive compensation in
the form of commissions or concessions from any such broker-dealer and/or the
purchasers of any such registered notes. Any broker-dealer that resells
registered notes that were received by it in the exchange offer for its own
account and any broker or dealer that participates in a distribution of such
notes may be deemed to be an "underwriter" within the meaning of the Securities
Act and any profit on any such resale of such notes and any commissions or
concessions received by any such persons may be deemed to be underwriting
compensation under the Securities Act. The letter of transmittal states that, by
acknowledging that it will deliver and by delivering a prospectus meeting the
requirements of the Securities Act, a broker-dealer will not be deemed to admit
that it is an "underwriter" within the meaning of the Securities Act.

     For a period of 180 days after the expiration of the exchange offer, we
will promptly send additional copies of this prospectus and any amendment or
supplement to this prospectus to any broker-dealer that requests such documents
in the letter of transmittal. We have agreed to pay all expenses incident to the
exchange offer, including the reasonable fees and expenses of counsel to the
initial purchasers of the old notes, other than commissions or concessions of
any brokers or dealers, and will indemnify holders of the notes, including any
broker-dealers, against certain liabilities, including liabilities under the
Securities Act.

                                 LEGAL MATTERS

     The validity of the notes has been passed upon for us by Kirkpatrick &
Lockhart LLP, Pittsburgh, Pennsylvania.

                                    PART II

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Section 145 of the Delaware General Corporation Law ("DGCL") provides that
a corporation may indemnify a director, officer, employee or agent made a party
to an action by reason of the fact that he was a director, officer, employee or
agent of the corporation or was serving at the request of the corporation,
against liabilities, costs and expenses actually and reasonably incurred by him
in his capacity as a director or officer or arising out of such action, if he
acted in good faith and in a manner he reasonably believed to be in, or not
opposed to, the best interests of the corporation and, with respect to any
criminal action, had no reasonable cause to believe his conduct was unlawful. No
indemnification may be provided where the director, officer, employee or agent
has been adjudged by a court, after exhaustion of all appeals, to be liable to
the corporation, unless a court determines that the person is entitled to such
indemnity. Article EIGHT of our Restated Certificate of Incorporation provides
that we will indemnify any person who was or is a party or is threatened to be
made a party or is otherwise involved in any action, suit or proceeding by
reason of the fact that he or she is or was a director or officer of the
Company, or is or was serving at our request as a director, officer, employee or
agent of another entity, against certain liabilities, costs and expenses. We are
also authorized to maintain insurance on behalf of any director, officer,
employee or agent of the Company or another entity against any expense,
liability or loss whether or not we would have the power to indemnify such
person against such expense, liability or loss under the DGCL.

     Section 102(b)(7) of the DGCL permits a corporation to relieve its
directors from personal liability for monetary damages to the corporation or its
stockholders for breaches of their fiduciary duty as directors except for (i) a
breach of the duty of loyalty, (ii) failure to act in good faith, (iii)
intentional misconduct or knowing violation of law, (iv) willful or negligent
violations of certain provisions of the DGCL (Sections 174, 160 and 173)
imposing certain requirements with respect to stock purchases, redemptions and
dividends or (v) any transaction from which the director derived an improper
personal benefit. Article SEVEN of our Restated Certificate of Incorporation
provides, among other things, that the personal liability of our directors is so
eliminated.

ITEM 22.  UNDERTAKINGS.

 The undersigned registrant hereby undertakes:

     To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:

     (i)  To include any prospectus required by Section 10(a)(3) of the
          Securities Act of 1933;

     (ii)  To reflect in the prospectus any facts or events arising after the
           effective date of the registration statement (or the most recent
           post-effective amendment thereof) which, individually or in the
           aggregate, represent a fundamental change in the information set
           forth in the registration statement. Notwithstanding the foregoing,
           any increase or decrease in volume of securities offered (if the
           total dollar value of securities offered would not exceed that which
           was registered) and any deviation from the low or high end of the
           estimated maximum offering range may be reflected in the form of
           prospectus filed with the Commission pursuant to Rule 424(b) if, in
           the aggregate, the changes in volume and price represent no more than
           a 20% change in the maximum aggregate offering price set forth in the
           "Calculation of Registration Fee" table in the effective registration
           statement; and

     (iii) To include any material information with respect to the plan of
           distribution not previously disclosed in the registration statement
           or any material change to such information in the registration
           statement.

Provided, however, that paragraphs (i) and (ii) do not apply if the information
required to be included in a post-effective amendment by those paragraphs is
contained in periodic reports filed by the registrant pursuant to section 13 or
section 15(d) of the Securities Exchange Act of 1934 that are incorporated by
reference in the registration statement.

     That, for the purpose of determining any liability under the Securities Act
of 1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

     To remove from registration by means of a post-effective amendment any of
the securities being registered which remain unsold at the termination of the
offering.

     That, for purposes of determining any liability under the Securities Act of
1933, as amended, each filing of the registrant's annual report pursuant to
Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended (and,
where applicable, each filing of an employee benefit plan's annual report
pursuant to Section 15(d) of the Securities Exchange Act of 1934), that is
incorporated by reference in the registration statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933, as amended, may be permitted to directors, officers and controlling
persons of the registrant pursuant to the foregoing provisions, or otherwise,
the registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in that Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being

                                       II-3


registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in that Act and will be governed by the final adjudication
of such issue.

     The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11, or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.

     The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

                                       II-4


                                   SIGNATURES


     Pursuant to the requirements of the Securities Act, the registrant has duly
caused this amendment to registration statement to be signed on its behalf by
the undersigned, thereunto duly authorized, in the City of Pittsburgh,
Commonwealth of Pennsylvania, on May 1, 2002.
