    The presentation will contain "forward-looking statements" within
the meaning of the Private Securities Litigation Reform Act of 1995.
Certain statements in the presentation will relate to future events
and expectations and, as such, constitute forward-looking statements.
Forward-looking statements include those containing such words as
"anticipates," "believes," "estimates," "expects," "would," "should,"
"will," "will likely result," "forecast," "outlook," "projects," and
similar expressions. Forward-looking statements are based on
management's current expectations and include known and unknown risks,
uncertainties and other factors, many of which we are unable to
predict or control, that may cause our actual results, performance or
achievements to materially differ from those expressed or implied in
the forward-looking statements. Important factors that could cause
actual results to differ materially from those in the forward-looking
statements include: (a) material adverse changes in economic or
industry conditions generally, including global supply and demand
conditions and prices for our specialty metals; (b) material adverse
changes in the markets we serve, including the aerospace and defense,
construction and mining, automotive, electrical energy, chemical
process industry, oil and gas, and other markets; (c) our inability to
achieve the level of cost savings, productivity improvements,
synergies, growth or other benefits anticipated by management,
including those anticipated from strategic investments and the
integration of acquired businesses, whether due to significant
increases in energy, raw materials or employee benefits costs, or
other factors; (d) volatility of prices and availability of supply of
the raw materials that are critical to the manufacture of our
products; and (e) other risk factors summarized in our Annual Report
on Form 10-K for the year ended December 31, 2005, and in other
reports filed with the Securities and Exchange Commission. We assume
no duty to update our forward-looking statements.
