James V.  Continenza of Lucent  becomes  senior vice  president  for  operations
strategy.

Vienna,  Va.,  September  8,  2000 -  Teligent,  a global  leader  in  broadband
communications,  today named John C. Wright, a partner in the Washington  office
of Ernst & Young, as its new chief financial officer.

Wright, 52, is a 29-year E&Y veteran who has extensive experience in mergers and
acquisitions,  international tax and finance, securities and regulatory matters.
For the past two years  Wright has served as the  senior  Ernst & Young  partner
managing the firm's relationship with Teligent.

"John has an intimate knowledge of our financial affairs, our business plan, our
internal  operations and the Teligent team. We're delighted that he has accepted
our offer to join us as we move Teligent to the next phase of its  development,"
said Teligent Chairman and Chief Executive Officer Alex J. Mandl.

A native of North  Carolina,  Wright  has  worked in Ernst & Young's  Washington
office  since  1987,  most  recently  as a  partner  in the  firm's  Technology,
Communications  and  Entertainment  Group. He originally joined Ernst & Young in
1971 in Charlotte, N.C.

Mandl also  announced  the  appointment  of James V.  Continenza  as senior vice
president  for  operations  strategy.  Continenza  had been  president and chief
executive officer of Lucent Technologies Product Finance.

In his 11 years at AT&T and Lucent, Continenza, 38, was promoted to increasingly
responsible  positions with AT&T's small business  division,  Lucent's  business
communications systems unit and Lucent Technologies Product Finance.

At Teligent,  Continenza  will work with the senior  management  team to improve
operations processes and help the company become more efficient and effective in
serving customers.

"Jim has a tremendous operational track record at Lucent, and I know he'll bring
great value to Teligent as we continue to streamline our operations and increase
our efficiency," Mandl said.

Mandl  also  announced  that  he  will  assume   responsibility  for  Teligent's
operations, effective immediately,  following the decision by Teligent President
and Chief  Operating  Officer  Kirby G.  "Buddy"  Pickle to accept a position as
chief executive officer of PF.Net, a fiber backbone company.

"During the past 20 years, my corporate life has been spent in senior operations
roles at companies such as AT&T and Sea-Land Services, Inc., The world's leading
shipping  company.   Now  I  will  assume  that  role  at  Teligent,   effective
immediately,  in addition to maintaining my  responsibilities as chairman of the
board," Mandl said.

"As Teligent's  first COO, Buddy Pickle played a key role in getting the company
up and running," Mandl added.  "Together,  we built our networks,  installed our
back office systems,  brought our first products to market and began serving our
first  customers.  As Buddy moves on to meet new challenges as a chief executive
officer, all of us at Teligent wish him the best."


Reporting to Mandl in his new role are: Hamid Akhavan, senior vice president and
chief technology officer; Steve Bell, senior vice president for human resources;
Continenza,  senior vice president for operations strategy;  Aki Debayo-Doherty,
senior vice president,  international;  Larry Harris,  senior vice president and
