Constantine “Deno” Macricostas, Chairman and Chief Executive Officer briefly discussed several important initiatives launched during the quarter. “First, I am excited that we have greatly expanded the depth and quality of our management team with the addition of Michael Luttati. As our new Chief Executive Officer, I am confident that he will lead the Photronics team to new highs. In terms of business opportunities, we have identified a number of areas where we believe we can grow our business at a rate to the mid-teens in fiscal 2005. In the areas of technology development and support, we have taken actions to extract greater efficiencies from our most advanced facilities. These include retasking the Austin site to focus exclusively on advanced masks at below the 130 nanometer process node, while also serving as the development center for both 65 nanometer and 45 nanometer solutions. Mainstream tool sets are being transferred to sites in Allen, Texas and Brookfield, Connecticut. Photronics has also opened its first corporate research & development center in Asia. Located in our Korean facility, this significantly enhances our position to accelerate our growth with technology-driven Asian customers requiring cost effective lithography solutions.” He added, “Photronics has also begun the expansion of its FPD mask capability. As we announced in March, we are expanding from our current position in Korea and into Taiwan. Customer support at a groundbreaking ceremony in Taichung, which was held just before the end of the quarter, was very strong. We are confident that we will be able to quickly expand our presence and grow our share in this market.”
