September 7, 2005 Monterey Park, CA -- Kotura, provider of silicon photonic products, has raised $13 million in Series 2 preferred stock financing. The financing round was led by new investor GF Private Equity Group and included the Viterbi Group, also a new investor. Existing investors ComVentures and ARCH Venture Partners also participated.

"Kotura has all the ingredients we look for in an investment: Unique technology, significant customer traction, and a strong team," contends David Fallace, vice president of GF Private Equity Group. "We believe that Kotura is well-positioned to become a dominant player in the emerging silicon photonics market."

Mr. Fallace will be joining Kotura's Board of Directors.

Kotura claims it is the only silicon photonics company shipping production quantities of silicon photonic products to customers. The components have achieved full Telcordia qualification and are deployed in live networks around the world, say company representatives.
