Teligent reports $31 million in 1999 revenue; expands reach to four continents

Vienna, Va., March 6, 2000 - Teligent, a global leader in broadband
communications, today reported revenue of $31.3 million for 1999 and $15.5
million for the quarter ending December 31, reflecting the company's first
full year of commercial operations.

Year-end 1999 revenue was up more than 3,000 percent from the $1 million in
revenue posted for 1998. Fourth quarter 1999 revenue was up 3,140 percent from
the $480,000 reported for the fourth quarter of 1998, and up more than 50
percent from the $10.3 million recorded for the third quarter of 1999.

"We had a tremendous year in 1999," said Chairman and Chief Executive Officer
Alex J. Mandl. "We grew our revenue, scaled our domestic business and built the
foundation for a major international effort. We built strong relationships with
a premier group of technology investors, including Liberty Media, Microsoft and
Hicks Muse.

"We created the foundation of our own Internet infrastructure. And we're moving
to quickly establish a

                                       1

significant presence in the world of e-business and Web-based applications.
We're in a great position to meet the challenges of 2000," Mandl said.

During 1999, Teligent established itself as the industry leader in rapidly
rolling out high-speed, lower-cost communications services by completing the
launch of service in 40 major U.S. markets in 14 months.

Teligent also set the stage for major international expansion, leading to recent
announcements of partnerships in Germany, France, Spain, Hong Kong and
Argentina. Teligent partnerships already have won spectrum rights in Germany,
Hong Kong and Argentina and today are developing local broadband communications
networks. Applications for spectrum are pending in France and Spain.

In 1999, Teligent took steps to become a full, facilities-based Internet access
and application services provider, initiating the construction of its own
Internet access infrastructure. Teligent recently completed a new data center in
Washington DC and has nearly finished a second data center in Chicago.
Construction of a third center in Northern California is underway. Today,
Teligent is carrying Internet traffic from initial "beta" customers through its
new ISP facilities in five markets.

These facilities are the foundation of Teligent's rapidly expanding "e-
enterprise" platform, which will build on the early success of Teligent's
proprietary, interactive business management tool "e?magineSM."

"In 1999, we built our business from a start-up into a major player providing
broadband access and services - both data and voice - to more than 15,000
customers throughout the United States. Now we're positioned to quickly build on
our domestic platform and export our success from North America to Europe, Asia
and South America," said President and Chief Operating Officer Kirby G. Pickle.

For the year ending December 31, 1999, Teligent reported a net loss of $529
million and negative EBITDA of $382 million, compared to a net loss of $281
million and negative EBITDA of $202 million for 1998. The net loss for the
fourth quarter was $154 million, compared to a net loss of $105 million in the
fourth quarter of 1998.

"These numbers reflect our record-breaking buildout of broadband communications
networks in 40 local markets across the United States," said Pickle. "At the
beginning of the year, we planned to invest significant time, energy and capital
to get our local networks up and running in as many markets as possible - and
we've been very successful in achieving that goal."

Teligent reported $262 million in capital expenditures in 1999, up from $183
million in 1998. Capital expenditures for the fourth quarter were $124 million,
up from $72 million in the fourth quarter of 1998. As of December 31, the
company reported fixed assets of $459 million and cash and short-term
investments of $557 million.

During the fourth quarter, Teligent secured new capital totaling $500 million
from an investor group led by Microsoft Corporation and private equity firm
Hicks, Muse, Tate & Furst Incorporated. Other investors were Chase Capital
Partners, DB Capital Partners and Olympus Partners.

"Teligent ended the year in a very strong cash position," said Acting Chief
Financial Officer Cindy L. Tallent. "The $500 million investment by the group
led by Microsoft and Hicks Muse affords us significant additional liquidity as
we continue to deploy our local broadband networks. We enter the year 2000 with
more than $1 billion in available cash and bank facilities."

As of December 31, 1999, Teligent's customer base had grown to more than 15,000,
double the 7,500 customers installed at the end of the third quarter of 1999,
and up more than 12 fold from the 1,176 customers installed at the end of 1998.

Teligent installed nearly 90,000 lines during the fourth quarter, more than
double the 39,000 lines installed during the third quarter. The number of lines
installed in the last three months of 1999 exceeded the total number of all
lines installed during the company's previous history.

In 1999, Teligent also made significant progress in gaining access to buildings,
with more than 7,500 building leases and options signed by the end of the year.
That figure represents a 31 percent increase over the 5,765

                                       2
<PAGE>

leases or options signed as of the end of the third quarter, and a 214 percent
increase over the 2,389 buildings under lease or option at the end of 1998.

During 1999, Teligent grew to 2,822 employees, up from 2,625 at the end of the
third quarter and up from 1,477 at the end of 1998.

At the end of 1999, Teligent had installed "last mile" broadband network
equipment in more than 3,000 buildings. Of those, 2,500 buildings have passed
Teligent's rigorous network certification procedure, and are officially "on-
net." That total represents an 18 percent increase in "on-net" buildings from
the third quarter, and a 13-fold increase from the end of 1998.

The number of "on-net" buildings with fixed wireless installations grew to more
than 1,000, up nearly 900 percent from the end of 1998 and up 17 percent from
the 915 wireless "on-net" buildings reported at the end of the third quarter.

Teligent's current domestic service territory encompasses more than 580 cities
and towns with a combined population of more than 100 million. More than 80 of
those cities have populations of 100,000 or more.

In an effort to extend the reach of Teligent's domestic network, reduce network
costs and increase network efficiencies, Teligent recently agreed to make a
strategic investment in ICG Communications, Inc. of Denver.

Under the terms of the agreement, Teligent will receive nearly three million
shares of ICG stock in exchange for one million shares of Teligent common stock.
The companies have signed a memorandum of understanding in which they agreed to
seek ways to leverage their network capabilities.

On the international front, Teligent has put in place a number of partnerships
that are expanding the company's reach overseas. They include:

 . A partnership in Germany with Mannesmann Arcor, the telecommunications
  subsidiary of industrial giant Mannesmann AG. By utilizing Teligent's German
  licenses in the 26 GHz band and Mannesmann Arcor's licenses in the 26 GHz and
  3.5 GHz band, the joint venture will have access to approximately one-third of
  the German population as well as Mannesmann Arcor's 4,200-mile fiber optic
  backbone.

 . A partnership in Hong Kong with HKNet, Co. Ltd., one of the largest Internet
  service providers in Hong Kong, and CCT Telecom Holdings, Ltd., an integrated
  communications company with operations in Hong Kong and China. The joint
  venture, HKNet-Teligent Co. Ltd. was awarded a market-wide spectrum license to
  offer communications services to businesses and residences. Among the partners
  in HKNet is Nippon Telegraph and Telephone of Japan, one of Teligent's
  earliest investors.

 . A partnership in France with LD COM, the telecommunications arm of the $20
  billion Louis Dreyfus Group, and Artemis, a global investment holding company.
  One of France's best-known communications brands, LD COM has built a fiber
  backbone covering much of the country. The joint venture has applied for
  licenses in the 24.5 - 26.5 GHz band to serve businesses in the major French
  markets.

 . A partnership in Argentina with Telcom Ventures, a U.S. based wireless pioneer
  that has licenses to build fixed wireless networks in the 24-25 GHz band in
  Argentina's major markets, including Buenos Aires. The licenses cover
  approximately 60 percent of Argentina's businesses.

 . A partnership in Spain with competitive communications company Jazztel, which
  is building state-of-the-art backbone and local fiber optic networks in major
  markets throughout Spain. The Teligent-Jazztel partnership has applied for
  spectrum in the 26 GHz band.

                   About Teligent's local broadband networks

Teligent's local communications networks represent the marriage of the latest
advances in high-frequency microwave technology with traditional broadband
wireline equipment. The integration of these technologies enables Teligent to
increase its local network efficiency and significantly lower network costs.

Teligent delivers fixed wireless services by installing small antennas on the
roofs of customer buildings. When a

                                       3
<PAGE>

customer makes a telephone call or accesses the Internet, the voice, data or
video signals travel over the building's internal wiring to the rooftop antenna.

These signals are then digitized and transmitted to a "base station" antenna on
another building, usually less than three miles away. Each base station antenna
gathers signals from a cluster of surrounding customer buildings, aggregates the
signals and then routes them to a broadband switching center.

At the switching center, ATM (Asynchronous Transfer Mode) switches and data
routers distribute the traffic to other networks, such as public circuit-
switched voice networks, packet-switched Internet and private data networks.
