Forward-Looking Statements

This press release contains, and the discussions in our subsequent conference call will contain, forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. These statements include: (i) any anticipation or guidance as to future financial performance, including future revenue, gross margin, operating expense, operating margin, EBITDA, cash flow and other financial metrics; and (ii) the Company's beliefs regarding the purpose, usefulness and efficacy of non-GAAP results and the measures and items the Company includes in the same, as well as any benefits to investors the Company believes its non-GAAP measures provide. These forward-looking statements involve risks and uncertainties that could cause actual results to differ materially from those projected. In particular, the Company's ability to predict future financial performance continues to be difficult due to, among other things: (a) continuing general limited visibility across many of our product lines exacerbated by the current credit and financial market uncertainty; (b) the ongoing potential for significant quarter-over-quarter product mix fluctuations, which can materially impact profitability measures due to the broad gross margin range across our portfolio; (c) continuing consolidation activities affecting our customer base, which, in the shorter term limits demand visibility, and, in the longer term, could reduce our business potential; (d) average selling prices continue to decline across our traditional Optical Communications and our Advanced Optical Technologies and Commercial Lasers businesses; (e) we and many of our Optical Communications suppliers continue to experience execution and delivery challenges which limit our revenue and impair our profitability; (f) our Communications Test and Measurement business is notable for seasonality and a significant level of in-quarter book-and-ship business, further limiting our forecasting abilities; (g) we are currently engaged in various product and manufacturing transfers, site consolidations and product discontinuances, which has caused and may continue to cause execution disruptions, customer satisfaction issues and quality and delivery problems; and (h) we are currently materially upgrading our ERP systems, which if not completed on-time and on budget could materially impair our business in the near term and create additional future expenses and customer dissatisfaction.

For more information on these and other risks affecting the Company's business, please refer to the "Risk Factors" section included in the Company's Annual Report on Form 10-K/A for the year ended June 28, 2008 filed with the Securities and Exchange Commission. The forward-looking statements contained in this news release are made as of the date hereof and the Company does not assume any obligation to update the reasons why actual results could differ materially from those projected in the forward-looking statements.
