BLUE BELL, Pa. & RESTON, Va./Jan. 21, 2002 -- Fiberlink, a leading provider of managed secure mobile access solutions, and Comerica Bank, a subsidiary of Comerica Incorporated (NYSE:CMA), announced today that Comerica's Technology and Life Sciences Division has provided the Pennsylvania company with a $7.5 million working capital facility. The funds will be used for general corporate purposes.

"As the business community grows increasingly mobile, Virtual Private Networks (VPNs) are becoming more and more important as a tool to improve productivity," said April Young, senior vice president and director of Comerica's Mid-Atlantic Technology and Life Sciences Division. "Fiberlink has established itself as a leader in the VPN space as a cash-flow positive company with a rapidly growing Fortune 1000 customer base. We are pleased to support its continued development with this working capital facility."

Founded in 1991, Fiberlink's mission is to enable enterprises to mobilize their businesses with secure, reliable connectivity to corporate data and applications through managed VPN solutions. Its team of professionals design, develop and deploy low-cost, high-performance communications solutions using redundant and diverse backbones, and superior local calling coverage with more than 10,000 points of presence (POPs) around the world. In late 2001, the Boston-based technology research firm, Yankee Group, identified Fiberlink as a leading company that meets stringent enterprise security demands.

"While Fiberlink is excited to have emerged as a leading provider of Internet-based VPNs, we realize the role of a service provider is to continue innovating to best serve the changing needs of its clientele," said Stephen Zarrilli, Fiberlink's CFO. "Getting this credit facility from Comerica Bank, a well-respected business bank with a strong technology-focused practice, will certainly assist us as we work toward developing technology for tomorrow."
