Cautionary Statement Concerning Forward-Looking Statements

This press release contains “forward-looking statements” that involve
risks and uncertainties. You can identify forward-looking statements
because they contain words such as “believes,” “expects,” “projects,”
“may,” “would,” “should,” “seeks,” “approximately,” “intends,” “plans,”
“estimates,” “anticipates” or similar expressions that relate to our
strategy, plans or intentions. All statements the Company makes relating
to its estimated and projected earnings, margins, costs, expenditures,
cash flows, growth rates and financial results or to its expectations
regarding future industry trends are forward-looking statements. In
addition, the Company, through its senior management, from time to time
makes or may make forward-looking public statements concerning its
expected future operations and performance and other developments. These
forward-looking statements are subject to known and unknown risks,
uncertainties and other factors that may change at any time, and,
therefore, the Company’s actual results may differ materially from those
that it expected. The Company derives many of its forward-looking
statements from its operating budgets and forecasts, which are based
upon many detailed assumptions. While the Company believes that its
assumptions are reasonable, the Company cautions that it is very
difficult to predict the impact of known factors, and, of course, it is
impossible to anticipate all factors that could affect the Company’s
actual results. Actual results may differ materially from these
expectations due to various risks and uncertainties, including: the
impact of our indebtedness; the effect of our ability to borrow money;
our ability to implement our business strategies, including acquisition
activities; our ability to continue implementing our balanced book
approach to substantially reduce the impact of fluctuations in metal
prices on our earnings and operating margins; shrinkage from processing
operations and metal price fluctuations, particularly copper; the
condition of various markets in which our customers operate, including
the housing and commercial construction industries; our ability to
maintain business relationships with our customers on favorable terms;
the impact of a loss in customer volume or demand or a shift by
customers of their manufacturing or sourcing offshore; our ability to
compete effectively with existing and new competitors; the effects of
industry consolidation or competition in our business lines; operational
factors affecting the ongoing commercial operations of our facilities,
including technology failures, regulatory approvals, permit issues,
unscheduled blackouts, outages or repairs or unanticipated changes in
energy costs; supply, demand, prices and other market conditions for our
products; our ability to accommodate increases in production to meet
demand for our products; government regulations relating to our products
and services, including proposed EPA regulations regarding the
registration and marketing of bactericidal copper products; our ability
to maintain effective internal control over financial reporting; our
ability to realize the planned cost savings and efficiency gains as part
of our various initiatives; workplace safety issues; our ability to
retain key employees; adverse developments in our relationship with our
employees or the future terms of our collective bargaining agreements;
rising employee medical costs; our ability to maintain the
confidentiality of our proprietary information, to protect the validity,
enforceability or scope of our intellectual property rights and manage
litigation regarding our intellectual property rights; fluctuations in
interest rates; and restrictive covenants in our indebtedness that may
adversely affect our operational flexibility.

More detailed information about these and other risks and uncertainties
are contained in the Company’s filings with the Securities and Exchange
Commission, including under “Risk Factors” and elsewhere in our Annual
Report on Form 10-K filed with the Securities and Exchange Commission
