SAFE HARBOR STATEMENT UNDER THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995
Matters discussed in this news release, including any discussion of or impact,
expressed or implied, on the Company's anticipated revenue growth, operating
results and future earnings per share contain forward-looking statements
(identified by the words "expect", "estimate", "project", "plans", "believe",
and similar expressions) that involve known and unknown risks and uncertainties.
For these statements the company claims the protection of the safe harbor of the
private Securities Litigation Reform Act of 1995. The company's results may
differ significantly from the results indicated by such forward-looking
statements. The Company's future results are dependent upon general economic
conditions, the availability of supplies of fiberglass, the ability to expand
new and existing markets, competition from competing product lines from both
fiberglass and non-fiberglass suppliers, the ability to manage growth in
inventory, the stability of its customers' capital spending plans and the
ability of the company to obtain necessary capital from time to time. These and
other risks are detailed from time to time in the Company's SEC reports,
including Form 10K for the year ended December 31, 1999.
