Santa Clara, CA February 27, 2002
Salira Optical Network Systems, Inc., the first company to develop a carrier-class access architecture for Ethernet Passive Optical Networks (EPON), today announced that it has raised an additional $7 million in new equity and debt financing. The new funding closes a Series B round of $22.1 million and brings the total investment in Salira to $29.1 million. Sofinnova Ventures becomes the latest investor to participate in Salira's Series B round which was led by Mobius (formerly Softbank) Venture Capital. Pac Rim Venture Partners and Manitou Ventures also participated in the official closing of the round. Salira also disclosed that it has secured a $2 million revolving credit facility from Heller Financial, a division of GE Capital.

"Access in 'the last mile' is the final bottleneck that must be fixed by the carriers in order for universal broadband access to be achieved," said Eric Buatois, Principal of Sofinnova Ventures. "Salira's optical access systems leverage the power of Ethernet, making Salira a leading company serving both service provider and enterprise customers.

The new funding will be used to accelerate deployment of Salira's systems into trials and general availability. The credit facility from Heller Financial provides Salira with added flexibility in financing its operations. The revolving line of credit will be used to finance equipment and inventory, and to prepare for the production, assembly and shipping of systems in the second half of 2002.

"We are very encouraged by the investment community's continued validation of our technology and our approach to the market," said Herbert J. Martin, CEO of Salira. "This new funding will enable us to accelerate the deployment of systems that deliver access to affordable broadband services."
