GERMAN NETWORK
On August 21, 1998, the Company announced that it had executed an agreement
with Metromedia Fiber Network and Carrier 1 Holdings Ltd. to jointly develop a
national fiber optic telecommunications network in Germany. The proposed
network, which will be developed through an entity owned 50.1% by the Company,
will expand the reach of the German portion of the Circe Network being developed
by the Company to include Dortmund, Bremen, Hamburg, Berlin, Leipzig, Nuremberg
and Munich. Upon completion, each of the Company, Metromedia Fiber Network and
Carrier 1 Holdings Ltd. will own its own separate broadband network. The
construction of the network is contingent upon both Metromedia Fiber Network and
Carrier 1 Holdings Ltd. meeting certain financing requirements.
For details on the Circe Network, see "Summary -- Circe Network" and
"Business -- Circe Network" in the Prospectus.
