Dark Fiber to Enable Greater Reach for Next-Generation California Regional Optical Network

ANN ARBOR, Mich. - December 19, 2005 - FiberCo(R), a fiber holding company supporting U.S. research and higher education, today announced that the Corporation for Education Network Initiatives in California (CENIC), has purchased the rights to over 709 route miles of dark fiber from FiberCo, under an agreement with Level 3 Communications (Nasdaq:LVLT). Utilizing FiberCo's national-scale wholesale structure and fiber acquisition process, CENIC acquired the dark fiber and will use the network facilities to
extend the reach of its network in support of research and higher education.

Through this fiber purchase, CENIC will enhance its ability to bring leading-edge capabilities to research and education institutions across California and the West by enabling it to directly connect its California Research and Education Network (CalREN) infrastructure to additional research and educational institutions, including neighboring Arizona State University (ASU) and University of Arizona.

According to Jim Dolgonas, president, CENIC, "The dark fiber services acquired through FiberCo further bolster our efforts and commitment to providing additional CENIC members with an extended platform for advanced collaboration and innovation."

Established in 2003 by Internet2(R), a consortium led by 207 universities working with government and industry to develop and deploy advanced networking technologies, FiberCo provides a means for acquiring, holding, and assigning dark fiber assets on both the national and the regional scales and on behalf of the higher education community.

"FiberCo continues to deliver on its mission to provide Internet2 members with critical optical networking assets which has facilitated the development of regional optical networks across the country," said Steve Cotter, director of network services for Internet2 and responsible for the FiberCo effort. "CENIC has long played a pioneering role in providing advanced Internet technology to its members and this latest dark fiber purchase demonstrates their ongoing commitment to this endeavor."
