Teligent reports $32m in second quarter revenue; local lines increase by nearly
two-thirds

Vienna,  Va.,  August  8,  2000  -  Teligent,   a  global  leader  in  broadband
communications,  today reported  second quarter  revenue of $32.3 million,  a 40
percent  increase  over the $23.1  million  in  revenue  reported  for the first
quarter and a gain of 700 percent year over year. Revenue from local service was
up 43 percent  compared to the first  quarter,  while data and Internet  revenue
rose 77 percent.

In addition to the strong revenue trends,  installed local lines for the quarter
were up 64 percent, the company's customer base grew 48 percent,  fixed wireless
building  installations rose 33 percent,  the total number of "on-net" buildings
grew 17 percent  and  building  access  rights for the first time broke the "one
billion square foot" mark.

During the quarter,  Teligent  launched a new  domestic  market - Columbus - and
added  another - Dayton - in July,  bringing  the total  number of U.S.  markets
served to 42. The company also signed a comprehensive network services agreement
with Level 3 Communications  Inc.,  giving Teligent access to Level 3's national
fiber backbone, regional fiber rings and metropolitan fiber networks.

"We're very pleased with our second quarter  results across the board - data and
voice, domestic and international," said Alex J. Mandl,  Teligent's Chairman and
Chief Executive  Officer.  "We're especially excited about the strong showing we
made in our local business. We posted record gains in local revenue,  local line
installations and new customers  ordering our local service.  It's apparent that
customers  continue  to demand a clear  choice for local  service  and that they
continue to want what Teligent offers."

On the international front,  Teligent and Mannesmann Arcor launched their German
joint venture,  ArcTel.  In France,  Teligent and partners LDCOM  Networks,  the
telecommunications  arm of the $20-billion  Louis Dreyfus Group, and Artemis,  a
global  investment  holding  company,  completed  work that led to last  month's
spectrum grant by the French government.

The Teligent-LDCOM-Artemis  joint venture was awarded eight regional licenses in
the  24.5 -  26.5GHz  band to  serve  businesses  in major  French  markets.  In
Argentina,  Teligent and its partner,  Telcom  Ventures,  began  deploying local
fixed wireless networks in Buenos Aires.

During the three  months  ending June 30,  Teligent  added  34,110  local lines,
bringing the total number of local lines to 87,516.  Lines  installed  for data,
Internet and related services rose by 180 percent. Total net line additions were
49,075.  Teligent  ended the quarter  with an adjusted  total of 358,556  lines,
representing  an increase of 25 percent over the first quarter and more than 850
percent from a year ago.

More than  12,400 of the new  local  lines  were  added  for  customers  already
subscribing to Teligent long distance service,  as the sales force continued its
efforts to bring more existing  customers onto Teligent's  local  networks.  (To
avoid  double  counting,  those 12,400 local lines are not included in the total
number of new lines added during the quarter,  but are counted only as new local
lines.)

Nearly  two-thirds of new customers  ordered local service,  while the number of
installed  local  customers  grew  by  33  percent.  Total  installed  customers
increased to 26,101,  up from 17,647 at the end of the first quarter.  Year over
year, Teligent's customer base rose nearly 640 percent.

                                 "On-net" focus

"The  significant  growth in our local  business - whether you measure  revenue,
lines or customers - reflects  our  continuing  focus on bringing  more and more
buildings  `on-net'," said Teligent  President and Chief Operating Officer Buddy
Pickle. "We continue to shorten  installation  intervals and expand the universe
of  buildings  for which we have  access  rights.  Together,  these  efforts are
driving our success in connecting more and more buildings to our local voice and
data facilities."

During the quarter,  Teligent  added 514  buildings to its  SmartWave(TM)  local
communications networks, all with fixed wireless connections, bringing the total
number of "on-net"  buildings  to 3,614.  At the end of the second  quarter,  57
percent  of  all  "on-net"  buildings  were  connected  through  fixed  wireless
technology, while 43 percent had wireline connections.

                           Progress on fixed wireless

"We've made tremendous progress with our fixed wireless  installations,"  Pickle
said. "One hundred  percent of all the buildings we brought  `on-net' during the
second  quarter were equipped  with fixed  wireless  technology.  I expect we'll
continue  to see even  more  improvements  in our  fixed  wireless  installation
procedures and results as we acquire rights to serve more and more buildings."

In the three  months  ending  June 30,  Teligent  added 1,650  buildings  to its
portfolio of real estate under lease or option,  raising the number of buildings
to which Teligent has access rights by 19 percent, to 10,343.

Teligent  announced  during the  quarter  that it had secured  access  rights to
buildings  with a  combined  total  of more  than  one  billion  square  feet of
commercial office space.

On the sales  front,  nearly 60  percent  of new  customers  ordered a bundle of
services,  while nearly two-thirds of new customers ordered local service. About
90 percent  ordered long  distance.  Data and Internet  orders by new  customers
increased by 50 percent compared to the first quarter.  Data sales per customer,
measured in dollars, rose 30 percent over the first quarter.

The Teligent sales force stood at 596 reps at the end of the second quarter,  up
38 percent  from the second  quarter of 1999.  Measured in full time  equivalent
reps with a minimum of three  months'  experience,  the sales  force grew to 379
from 303 during the same year-over-year period. The total Teligent work force at
the end of the  second  quarter  stood at 3,184,  up 11  percent  from the first
quarter.

Teligent reported a net loss of $164 million for the second quarter, compared to
$156 million for the first quarter.  Capital expenditures for the second quarter
were $85 million,  compared to $90 million in the first quarter.  As of June 30,
the company reported  available cash and short-term  investments of $291 million
and total assets of $1.1  billion,  compared to $286  million and $970  million,
respectively, as of March 31.

"Our operational and financial metrics demonstrate our continued strength," said
Acting Chief Financial  Officer Cindy Tallent.  "With nearly one billion dollars
in available liquidity,  we have the financial flexibility and resources we need
to drive our success in the marketplace."

                       About Teligent's broadband networks

Teligent's local communications networks represent the integration of the latest
advances in  high-frequency  microwave  technology  with  traditional  broadband
wireline equipment.  Together these technologies enable 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 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.
