                       WIRELESS LICENCES THROUGHOUT CANADA

 --TD Capital Group Limited joins Wispra Inc. and NEXTLINK in venture named as
   provisional winner for broadband wireless in Toronto, Montreal, Vancouver,
                        Ottawa, Edmonton and Calgary --

Montreal, December 9, 1999 -- Wispra Networks, Inc. announced today that it has
submitted its completed broadband wireless 24/38 GHz spectrum licence documents
and initial licence payment to Industry Canada following being named provisional
winner of six fixed broadband wireless licences. The licences cover 14.3 million
population in Toronto, Montreal, Vancouver, Ottawa, Edmonton, Calgary and
surrounding areas.

Wispra Networks also announced the signing of a shareholder's agreement between
TD Capital Group, a leading Canadian private equity investor in the
communications and media industry; NEXTLINK International, Inc., a subsidiary of
McLean, Virginia-based NEXTLINK Communications, Inc.; and Wispra Inc., a
long-time participant in Canada's broadband wireless marketplace. Wispra
Networks anticipates the filing of the licence documents and payments of the
balance of licence fee will result in Industry Canada officially issuing
licences for the spectrum early next year.

Wispra Networks will pay a total of $74 million ($50.1 million in US dollars)
for 400 MHz of spectrum in the six market areas. The broadband wireless licences
won by Wispra Networks are located in the 24 GHz band and will be used to
facilitate the deployment of broadband wireless services and to further the
Canadian Government's objective "to place Canada in the forefront of the
information revolution by making Canada the most connected nation in the world."

"We're pleased to have joined Wispra Networks in this initiative and believe
that TD Capital brings a unique understanding of the Canadian telecommunications
marketplace," said David McCann, Managing Director of TD Capital. "We have a
longstanding institutional relationship with NEXTLINK and believe this
initiative will help shape the manner in which businesses in Canada participate
in the telecommunications revolution."

"We are very committed to successfully using fixed wireless as a robust
broadband access technology both in Canada and in the United States," said
NEXTLINK Chairman and Chief Executive Officer Dan Akerson. "NEXTLINK expects
that Wispra Networks will be a very strong competitor in Canada."

NEXTLINK is the largest holder of broadband fixed wireless licences in North
America, holding 82 licences that cover 95 percent of the population in the top
30 markets in the United States.






The company began field trials of both point-to-point and point-to-multipoint
service in Los Angeles and Dallas in September of this year.

"The promise of broadband wireless services will now become a reality in
Canada," said Joe Church, president of Wispra Networks. "Wispra Inc. was among
the pioneers in broadband wireless services in Canada and is proud to be among
the first to successfully participate in this historic auction."

TD Capital was established in 1968 as the first Canadian bank-owned provider of
private capital to businesses and is currently one of the leading private equity
firms in Canada.

NEXTLINK was founded in 1994 by telecommunications pioneer Craig O. McCaw to
provide high quality, broadband communications services to businesses over fiber
optic and broadband wireless facilities across North America.
NEXTLINK currently is providing service in 48 markets in the United States.

Wispra Inc. was founded in 1997 by Joe Church and associates to provide
broadband telecommunications services in Canada using emerging wireless
telecommunications technologies on new radio frequencies above 20 GHz.
