Forward-Looking Statements
All statements other than statements of historical fact included in this news release regarding financial performance, condition and operations and the business strategy, plans, anticipated revenues, bookings, market acceptance, growth rates, market opportunities and objectives of management of the Company for future operations are forward-looking statements. Forward-looking statements provide management’s current expectations or plans for the future operating and financial performance of the Company based upon information currently available and assumptions currently believed to be valid. Forward-looking statements can be identified by the use of words such as “anticipate,” “believe,” “estimate,” “expect,” “intend,” “plan(s),” “strategy,” “project” and other words of similar meaning in connection with a discussion of future operating or financial performance. Actual results could differ materially from those contemplated by the forward-looking statements as a result of certain factors. Among the important factors that could cause actual events to differ materially from those in the forward-looking statements are fluctuations in capital spending of our customers; fluctuations in revenues to our major customers; manufacturing and supplier risks; risks of booking cancellations, push-outs and de-bookings; dependence on timing and market acceptance of new product development; rapid technological and market change; risks in international operations; risks related to the reorganization of our business; dependence on proprietary technology and key personnel; length of the revenue cycle; environmental regulations; investment portfolio returns; fluctuations in our stock price; the risk that anticipated growth opportunities may be smaller than anticipated or may not be realized; risks related to business acquisitions, including the acquisition of substantially all the assets of ASML US, Inc.’s Richmond, California facility, and integration of the business and employees; the risk related to the Company’s recent changes to senior management; and the risks associated with the recovery from the recent earthquake, tsunami and nuclear disaster in Japan and its impact on our customers, suppliers, and operations. Zygo Corporation undertakes no obligation to publicly update or revise forward-looking statements to reflect events or circumstances after the date of this news release except as required by law. Further information on potential factors that could affect Zygo Corporation’s business is described in our reports on file with the Securities and Exchange Commission, including our Form 10-K for the fiscal year ended June 30, 2010, filed with the Securities and Exchange Commission on September 13, 2010.

Non-GAAP Measures
In this press release, we have presented certain financial measures which have not been determined in accordance with generally accepted accounting principles (GAAP) and are therefore non-GAAP financial measures. Non-GAAP operating profit (loss), as adjusted, non-GAAP net earnings (loss), as adjusted, and non-GAAP net earnings (loss) per share, as adjusted, are operating performance measures defined by the Company and used by the Company’s management to evaluate its operating activities, and a reconciliation of those amounts to reported results is presented below. These non-GAAP financial measures are not intended to replace and should not be considered as alternatives to reported amounts of operating profit (loss), net earnings (loss) or net earnings (loss) per share, which, respectively, are the most directly comparable GAAP financial measures. The Company believes that providing such a reconciliation is useful to users of the financial statements, since it excludes certain significant and unusual charges in the Company’s results, thus enhancing comparability of the Company’s results between periods presented.
