Sources of Supply

– The principal materials used in the manufacture of the Company's high-technology printed circuit materials and advanced composite materials, structures and assemblies are specially manufactured copper foil, fiberglass cloth and synthetic reinforcements, and specially formulated resins and chemicals. Although there is a limited number of qualified suppliers of these materials, the Company has nevertheless identified alternate sources of supply for many of such materials. While the Company has

not

experienced significant problems in the delivery of these materials and considers its relationships with its suppliers to be strong, a disruption of the supply of material from a principal supplier could adversely affect the Company's business. Furthermore, substitutes for these materials are

not

readily available, and an inability to obtain essential materials, if prolonged, could materially adversely affect the Company’s business.
