Spire Corporation's (the "Company") wholly owned subsidiary, Bandwidth Semiconductor, LLC (Bandwidth), entered into a five-year manufacturing agreement in which it will be the exclusive supplier to Principia Lightworks, Inc. (Principia), of semiconductor wafers, enabling Principia, a Woodland Hills, California firm, to begin high volume production of its patented device, an electron beam pumped vertical cavity surface emitting laser (eVCSEL) as a light source for projection display applications, including rear-projection consumer television (RPTV). Under the terms of this agreement, Bandwidth will be producing III/V and II/VI wafers for Principia with full production expected to start in mid 2007. During the first three years of the agreement, Bandwidth anticipates revenues will be in excess of $16 million, which includes revenue from the production of wafers and recognition of certain nonrecurring engineering and facility access payments. Bandwidth will begin the scale-up of its existing metal organic chemical vapor deposition (MOCVD) and related processing facilities to satisfy Principia's requirements. Principia has made an up-front payment for nonrecurring engineering and facility access costs and, in addition will make monthly facility availability payments throughout the term of the agreement. Although the Company will be committing capital resources to complete the scale-up, it anticipates the up-front payment plus the monthly payments will be sufficient to meet its capital requirements under the agreement, and providing the parties meet their respective obligations over the term of the Agreement, no net outlay of capital will be needed.
