The Private Securities Litigation Reform Act of 1995 contains certain safe harbors regarding forward-looking statements. From time to time, information provided by the Company or statements made by its directors, officers or employees may contain "forward-looking" information subject to numerous risks and uncertainties. Any statements made in this registration statement, including any statements incorporated herein by reference that are not statements of historical fact are forward-looking statements (including, but not limited to, statements concerning the characteristics and growth of the Company's market and customers, the Company's objectives and plans for future operations and products and the Company's expected liquidity and capital resources). Such forward-looking statements are based on a number of assumptions and involve a number of risks and uncertainties, and, accordingly, actual results could differ materially. Factors that may cause such differences include, but are not limited to: the continued and future acceptance of the Company's products; the rate of growth in the industries of the Company's products; the presence of competitors with 2 3 greater technical, marketing and financial resources; the Company's ability to promptly and effectively respond to technological change to meet evolving customer needs; capacity and supply constraints or difficulties; and the Company's ability to successfully expand its operations. For a further discussion of these and other significant factors to consider in connection with forward-looking statements, reference is made to the discussion in this registration statement under the heading "Risk Factors."

The proceeds from any sales of Shares offered hereby by the Selling Stockholders will not be received by the Company. The Company understands that any distribution of securities by the Selling Stockholders, or by pledgees, donees, transferees or their successors in interest, may be effected from time to time in one or more of the following transactions: (a) to underwriters who will acquire the Shares for their own account and resell them in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale (any public offering price and any discount or concessions allowed, re-allowed or paid to dealers may be changed from time to time); (b) through brokers, acting as principal or agent, in transactions, in special offerings, in exchange distributions pursuant to the rules of the applicable exchanges or in the over-the-counter market, or otherwise, at market prices prevailing at the time of sale, at prices related to such prevailing market prices, at negotiated prices or at fixed prices; or (c) directly or through brokers or agents in private sales at negotiated prices, or by any other legally available means. The Selling Stockholders and underwriters, brokers, dealers or agents, upon effecting the sale of the Shares, may be deemed to be an underwriter, as that term is defined by the Securities Act and any profit on any resale of securities may be deemed to be underwriting discounts and commissions. In order to comply with the securities laws of certain states, if applicable, the Shares will be sold in such jurisdictions only through registered or licensed brokers or dealers. In addition, in certain states the Shares may not be sold unless the Shares have been registered or qualified for sale in such state or an exemption from registration or qualification is available and complied with. The Company will file during any period in which offers or sales are being made one or more post-effective amendments to the Registration Statement of which this Prospectus is a part to describe any material information with respect to the plan of distribution not previously disclosed in this Prospectus or any material change in such information.

DISCLOSURE OF COMMISSION POSITION ON INDEMNIFICATION FOR SECURITIES ACT LIABILITIES The Restated Certificate of Incorporation of the Company contains provisions which grant broad rights of indemnification to the officers and directors of the Company. The Company has also entered into indemnification agreements with each of its executive officers and directors containing additional provisions of indemnification. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling the Company pursuant to the foregoing provisions, the Company has been informed that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable. 4 5 ========================================================================================================== No dealer, sales representative or any other person has been authorized to give information or make any representation not contained in this Prospectus in connection with the offer made by this Prospectus and, if given or made, such information or representation must not be relied upon as 470,589 SHARES having been authorized by the Company.
