September 6, 2005

Cardinal CG Company has finalized the requirements to acquire the assets of JDS Uniphase’s projection television mirror business in an agreement that was concluded on July 15, 2005.

JDS Uniphase (JDSU) is engaged in the business of producing mirrors for projection televisions, home theaters, video walls and other audio / visual applications. JDSU is recognized today as a world leader in this segment of the market. Cardinal Coated Glass (CG) Company, a fully owned subsidiary of Cardinal Glass Industries, Inc., is a world leader in magnetron sputtering, a process that today is used to produce a wide range of products – Front Surface Mirrors (FSM’s) being one of them. In making this announcement, Steve Nelson, Vice President of Cardinal CG Company, commented that this business is a solid match for Cardinal’s existing operations. Nelson states “Cardinal is the world leader in sputter coating technology. This expertise and understanding will fit perfectly with the highly technical FSM coating business. Cardinal CG Company will look to leverage our knowledge and production base to support the current requirements, bringing this experience and capacity to bear on this growing and highly competitive market.”

Dick Vegsund, JDSU Product Line Manager, stated that this move will allow JDSU to focus its resources on opportunities more consistent with its core competencies and new strategic direction. It is expected that the full transfer of the business will be completed on or about March 1, 2006. In the meantime, JDSU in Santa Rosa will continue to handle all elements of the business with respect to sales, mirror fabrication, order fulfillment and customer service.

Cardinal CG Company, using their operation located in Tumwater, WA, will assume the complete production of the mirror products. This new group will be called Cardinal Optical Mirror Division – or Cardinal OMD. “Becoming in essence a fully integrated producer will afford the necessary synergies required for us to compete in this exciting field” says Nelson. Nelson adds, “Cardinal will be contributing further assets to ensure that we are properly positioned to support the growth and quality requirements associated with this application. Cardinal is building a 150,000 ft² facility to house new fabricating and inspection lines for this business. In conjunction with this, Cardinal is also building its fifth, state-of-the-art float glass facility approximately 45 minutes away from Tumwater in the town of Winlock, WA. This new float glass facility will incorporate Cardinal’s current world class production capabilities with additional technologies necessary to produce the glass substrate required for FSM’s. Steve summarizes the overview by stating “We look forward to the challenges that await us in this exciting field, and are committed to bring the same energy, focus and commitment that have served us thus far in our core glass businesses.”
