            "Safe Harbor" Statement under the Private Securities Litigation
Reform Act of 1995: Any statements made in the conference call or set forth in
the news release that are not entirely historical and factual in nature are
forward-looking statements. For instance, all statements of belief and
expectations are forward-looking statements. Forward-looking statements are
inherently subject to risks and uncertainties, some of which cannot be predicted
or quantified. Potential risks and uncertainties include, but are not limited
to, such factors as the difficulties regarding the making of estimates and
projections, hiring and retention of qualified technical personnel in a
competitive labor market, acquiring and integrating new operations or assets,
closing or disposing of operations or assets, rapidly changing technology and
product obsolescence, the ability to realize cost savings or productivity gains,
the ability to improve capacity utilization, potential cost increases, the
strength and competitive pricing environment of the marketplace, demand for and
acceptance of the company's products, the results of in-process or planned
development, marketing and promotional campaigns, changes in demand for
products, difficulties foreseeing future demand, effects of limited visibility
of future sales, potential non-realization of expected orders or non-realization
of backlog, business and economic conditions or adverse changes in current or
expected industry conditions, business disruptions, future effects of the tragic
events of September 11, customer order preferences, fluctuations in market
prices of the company's common stock and availability of additional capital on
favorable terms, difficulties in implementing company strategies, environmental
matters, litigation, difficulties protecting patents and other proprietary
rights, inventory obsolescence. In addition to these factors and any other
factors mentioned elsewhere in this news release, the reader should refer as
well to the factors, uncertainties or risks identified in the Company's most
recent Form 10-K filed on December 24, 2001, the Form 10-Q filed on February 13,
