The Mandl Employment Agreement
- ------------------------------
     The Mandl Employment Agreement took effect September 1, 1996 and
expires on September 1, 2002, unless further extended pursuant to its
terms. Under the Mandl Employment Agreement, Mr. Mandl is entitled to
a minimum salary of $500,000 per annum (which may be increased from time
to time at the discretion of the Board after the first two years) and an
annual bonus of $500,000 per annum for the first three fiscal years of
employment, subject to increase after three years at the discretion of
the Board. After such period, Mr. Mandl shall also be entitled to
participate in all annual non-equity-based executive compensation plans.
Pursuant to the Mandl Employment Agreement, Mr. Mandl (a) has received a
$15 million recourse loan from MSI and DSC (see "Certain Relationships
and Related Transactions--Loans to Executive Officers") and (b) will be
entitled to a $5 million special payment upon the fifth anniversary of
his employment. The recourse loan will be automatically forgiven (i)
twenty percent in year one, twenty percent in year two, and sixty percent
in year five, (ii) upon the termination of his employment by him for
Good Reason (as defined in the Mandl Employment Agreement) or by the
Company without Cause (as defined in the Mandl Employment Agreement)
or (iii) his death or disability.

     The Mandl Employment Agreement provides that if either MSI or DSC
sells any of their respective member interests in the Company to a third
party, such seller shall be obligated to require the purchaser of such
interests to purchase, and may require Mr. Mandl to sell to such third
party, a proportionate percentage of the vested equity interest
represented by Mr. Mandl's CARs valued as of the date of such purchase,
at the same price paid by the third party for the interests of such seller.
The Mandl Employment Agreement also provides for a right of first refusal
on the part of MSI and DSC with respect to the disposition by Mr. Mandl
of an equity interest in the Company. In the event of a Change in Control
of the Company (as defined in the Mandl Employment Agreement), all CARs
shall vest immediately, the principal balance remaining on the $15 million
loan shall be immediately forgiven and the remainder of the $5 million
fifth anniversary special payment shall be paid.

     In addition, in the Mandl Employment Agreement the Company granted
Mr. Mandl certain registration rights with respect to the shares of Class
A Common Stock which are subject to the options into which the CARs were
converted pursuant to the Conversion described under "Stock Options"
(such shares as to which such registration rights apply being referred
to as "Mandl Registrable Securities", and the number of such shares as
of the date Teligent, L.L.C. was converted to a corporation (the
"Conversion Date"), as adjusted for splits, combinations and the like,
being referred to as the "Maximum Amount"). Under the Mandl Employment
Agreement, the Company is required, if requested by Mr. Mandl, to use its
reasonable best efforts to cause to be included in any registration
statement with respect to a public offering of shares of Class A Common
Stock, a number of shares of Mandl Registrable Securities proportionate
to the number of shares of Common Stock then owned by MSI and the Telcom
Stockholder which are included in such registration statement (based on
the total number of shares of Common Stock then owned by MSI and the
Telcom Stockholder, and the Maximum Amount, respectively). Because no
shares of Common Stock were sold by MSI or the Telcom Stockholder in the

                                  -7-


Equity Offerings, Mr. Mandl had no right to, and did not, sell any Mandl
Registrable Securities in the Equity Offerings. In addition, in each of
four twelve-month periods, the first of which commences on the Conversion
Date and each of the remaining three of which commences on each of the
remaining three respective subsequent anniversaries thereof, the Company
is required, if requested by Mr. Mandl (which request may not be made
prior to six months after consummation of the Equity Offerings), to use
its reasonable best efforts to promptly cause to be registered under the
Securities Act for public sale by Mr. Mandl a number of Mandl Registrable
Securities constituting at least 25% of the Maximum Amount (the "Maximum
Annual Amount"), provided that in no event may Mr. Mandl sell publicly
more than the Maximum Annual Amount in any such twelve-month period.  The
Company has filed a registration statement on Form S-8 registering shares
of Class A Common Stock authorized for issuance under the Stock Plan,
including the Mandl Registrable Securities.

     The Mandl Employment Agreement (other than certain restrictive
covenants of Mr. Mandl and certain severance obligations of the Company)
may be terminated (a) by the Company (i) without Cause by giving 30-days 
notice or (ii) for Cause upon the Board's confirmation that the employee
has failed to cure the grounds for termination within ten days after
notice thereof by the Company and (b) by Mr. Mandl (i) without Good
Reason by giving a 120-day notice or (ii) for Good Reason upon the
Company's failure to cure the grounds for termination within 20 days
after notice thereof by Mr. Mandl. The Mandl Employment Agreement
prohibits disclosure by Mr. Mandl of any Company confidential
information at any time. In addition, while he is employed by the
Company and for two years thereafter, Mr. Mandl is prohibited from
engaging or significantly investing in competing business activities
and from soliciting any Company employee to be employed elsewhere.

held by DSC at the time of consummation of the Equity Offerings.  In
addition, in the Members Agreement, Associated and MSI agreed with DSC
that upon a "Change in Control" (as defined in the Members Agreement) of
Associated or MSI, (i)Associated will immediately convert, and cause its
controlled affiliates (ii) to immediately convert, all of the Series B-1
Common Stock owned by them into Class A Common Stock such that, under the
Company's Certificate of Incorporation as then in effect, Associated,
alone or together with its controlled affiliates, will no longer have the
right to elect a majority of the Company's Board, (ii) MSI will cause
its designees on the Company's Board to cause the Board to convene a
meeting of the Company's stockholders and (iii) promptly after taking
the action described in (ii) immediately above, MSI will cause such
number of its designees on the Company's Board to resign so that such
designees no longer constitute a majority thereof.  In the Members
Agreement, each of Associated and MSI also agreed with DSC that it will
not transfer control of any entity which holds Class B Common Stock of
the Company to any third party (other than an affiliate of Associated,
provided such affiliate agrees to be bound by the provisions of the
Members Agreement applicable to MSI) without the consent of DSC unless,
concurrently with or prior to such transfer, AGI and MSI take the
actions described in clauses (i) through (iii) above.  In addition,
in the Members Agreement, MSI and the Telcom Stockholder granted to
each other rights of first refusal and co-sale rights with respect to
any sale or transfer by the other (other than to an affiliate or
pursuant to a pledge arrangement, and excluding any public sale or
distribution whether pursuant to a registration statement, Rule 144
or otherwise) of shares of Common Stock (other than Common Stock acquired
in public market transactions).  Pursuant to the Members Agreement,
Associated and the owners of the Telcom Stockholder also granted to
each other rights of first refusal and co-sale rights, with the same
exceptions, with respect to any sale or transfer by the other of shares
of MSI, or member or other equity interests of the Telcom Stockholder,
but only if shares of Common Stock constitute all or substantially all
of the assets of MSI or the Telcom Stockholder, respectively.

Common Stock
- ------------
     Voting Rights.   Except as otherwise required by law or, as described
below, by the Certificate of Incorporation, the holders of shares of Common
Stock will vote together as a single class.  Each share of Common Stock
will entitle the registered holder thereof to one vote.  There will be no
cumulative voting.

     The holders of Series B-1 Common Stock voting as a separate class,
will be entitled to elect that number of directors equal to the minimum
number necessary to constitute a majority of members of the Company's
Board of Directors (the "Series B-1 Directors"); provided however, that
if at any time the number of issued and outstanding shares of Series B-1
Common Stock (exclusive of any shares held in the Company's treasury or by
subsidiaries of the Company) is less than 20% of the aggregate number of
issued and outstanding shares of Common Stock (exclusive of shares held in
the Company's treasury or by subsidiaries of the Company) then, without any
further action of any party of the Company, all of such issued and
outstanding shares of Series B-1 Common Stock will automatically and
irrevocably be converted into an equal number of shares of Class A Common
Stock and the holders of Series B-1 Common Stock so converted will no
longer be entitled to elect Series B-1 Directors.

     The holders of Series B-2 Common Stock voting as a separate class,
will be entitled to elect one member of the Company's Board of Directors
(the "Series B-2 Directors"); provided however, that if at any time the
number of issued and outstanding shares of Series B-2 Common Stock
(exclusive of any shares held in the Company's treasury or by subsidiaries
of the Company) is less than 10% of the aggregate number of issued and

                                  -11-


outstanding shares of Common Stock (exclusive of shares held in the
Company's treasury or by subsidiaries of the Company) then, without any
further action of any party of the Company, all of such issued and
outstanding shares of Series B-2 Common Stock will automatically and
irrevocably be converted into an equal number of shares of Class A Common
Stock and the holders of Series B-2 Common Stock so converted will no
longer be entitled to elect a Series B-2 Director.

     The holders of Class A Common Stock and Class B Common Stock voting
together as a single class will be entitled to elect all members of the
Company's Board of Directors, other than any Series B-1 Directors, Series
B-2 Director or Series B-3 Director (the "Common Directors").

     The holders of Series B-3 Common Stock, voting as a separate class,
will be entitled to elect one member of the Company's Board of Directors
(the "Series B-3 Director), subject to adjustment in certain circumstances.
Any series B-1 Director, Series B-2 Director or Series B-3 Director
may be removed with or without cause, but only by the affirmative vote of
the holders of a majority of the shares of the series of Class B Common
Stock entitled to elect such director, voting as a separate class.  Any
Common Director may be removed with or without cause, but only by the
affirmative vote of the holders of a majority of the shares of Class A
Common Stock and Class B Common Stock voting together as a single class.

     Conversion into Series A Common Stock.  Pursuant to the Certificate
of Incorporation, each share of Class B Common Stock will be convertible
at any time, at the option of the registered holder thereof, into one fully
paid and nontransferable share of Class A Common Stock, subject to
adjustment for any stock split.

Stockholders Agreement
- -----------------------
     Prior to the consummation of the Equity Offerings, the Company 
entered into a Stockholders Agreement (the "Stockholders Agreement") 
with NTTA&T and the other stockholders of the Company (other than the 
FirstMark Sole Stockholder) (the "Stockholder Parties") whereby, NTTA&T 
and the Telcom Stockholder have certain rights and obligations with 
respect to their ownership interest in, and the governance of, the 
Company.  The Stockholders Agreement also provides that so long as the 
Telcom Stockholder and NTTA&T, respectively, have the right to elect a 
member of the Company's Board, the Company will afford to representatives 
of the Telcom Stockholder and NTTA&T, respectively, certain business
consultation rights as defined in the Stockholders Agreement.  Under the
Stockholders Agreement, so long as NTTA&T and the Telcom Stockholder,
respectively, have the right to elect a member of the Company's Board,
such respective members of the Company's Board or their designated
representative have visitation rights at meetings of all significant
internal operating committees and will be a member of any technical,
compensation or audit committees or any other committee of the Board.
Pursuant to the Stockholders Agreement, so long as NTTA&T is entitled 
to elect a member of the Company's Board, NTTA&T has the right, at its 
expense, to secund to the Company employees of NTTA&T or its affiliates 
(not exceeding a total of five such employees in any three month period)
to observe the Company's operations, including its technical and marketing
activities (such secunded employees being referred to as the "Secunded
Employees").  NTTA&T's right to elect a director to the Company's Board
terminates (as a result of the automatic conversion of all Series B-3
Common Stock into Class A Common Stock), thereby terminating NTTA&T's 
rights under the Stockholders Agreement as described above, if at any
time the number of issued and outstanding shares of Series B-3 Common
Stock is less than (i) 3% of the aggregate number of issued and
outstanding shares of Common Stock (exclusive of shares held in the
Company's treasury or by the subsidiaries of the Company) or (ii) 50% of
the aggregate number of shares of Series B-3 Common Stock issued and
outstanding (exclusive of shares held in the Company's treasury or by
the subsidiaries of the Company) immediately following the Reorganization
or if NTTA&T or any of its affiliates engage in certain activities which
are competitive with the Company as provided in the Certificate of
Incorporation.  The Telcom Stockholder's right to elect a director to
the Company's Board terminates (as a result of the automatic conversion
of all Series B-2 Common Stock into Class A Common Stock), thereby
terminating the Telcom Stockholder's rights under the Stockholders
Agreement as described above, if at any time the number of issued and
outstanding shares of Series B-2 Common Stock is less than 10% of the

                                  -12-


aggregate number of issued and outstanding shares of Common Stock
(exclusive of shares held in the Company's treasury).  The Stockholder's
Agreement also provides that the Stockholder Parties will vote for the
election of the Company's Chief Executive Officer as a member of the
Company's Board.

     To enable NTTA&T to benefit from secunding the Secunded Employees 
in the Stockholders Agreement, the Company granted to NTTA&T and its 
affiliates a non-exclusive, perpetual, irrevocable, royalty free right 
and license to use, solely in the business of NTTA&T and its affiliates 
outside the United States, such product, service, marketing, operational 
and technical information of the Company as shall be learned or obtained 
by the Secunded Employees.  Such right and license does not include any 
specific patent, copyright, trademark, tradename or similar property 
rights of the Company and will not be assignable to any third party. 

     The Stockholders Agreement also provides that until November 13, 1999,
the second anniversary of the First Closing under the NTT Purchase 
Agreement, each Stockholder Party must continue to hold at least one-half 
of the shares of Common Stock held by such Pre-IPO Stockholder as of the 
Second Closing under the NTT Purchase Agreement, except that such 
requirement lapses and is without further effect automatically as to NTTA&T 
and the Telcom Stockholder, respectively, if a Consultation Event occurs 
even though NTTA&T or the Telcom Stockholder, respectively, has objected 
thereto.  Under the Stockholders Agreement, if such requirement so 
lapses with respect to the Telcom Stockholder and, at the time of such 
lapsing, MSI is not entitled, pursuant to the Certificate of 
Incorporation, to elect a majority of the members of the Company's 
Board, then such requirement also lapses and is without further effect 
with respect to MSI.  In addition, in the Stockholders Agreement, MSI 
and the Telcom Stockholder have granted to NTTA&T co-sale rights with 
respect to any sale or transfer by either of them (other than to an 
affiliate or pursuant to a pledge arrangement, and excluding any public 
sale or distribution whether pursuant to a registration statement, Rule 
144 or otherwise) of shares of Common Stock (other than Common Stock 
acquired in public market transactions). 

     The Stockholders Agreement also provides for certain rights and 
obligations relating to the Company's compliance with the foreign 
ownership restrictions under the Communications Act of 1934 and the 
rules, regulations and decisions of the FCC.

Loans to Executive Officers
- ---------------------------
     On September 1, 1996, Mr. Mandl was obligated to MSI and DSC in 
the form of loans for an aggregate principal amount of $15.0 million at 
an interest rate of 6.53% per year, which principal and interest accrued 
thereon will become due and payable on September 3, 2001. On September 
1, 1997, the first anniversary of Mr. Mandl's employment with the 
Company, 20% of the principal and all underlying accrued interest was 
forgiven.  The remaining principal amount will be forgiven as to 20% 
thereof and the incremental underlying accrued interest on the second 
anniversary of his employment with the Company and as to 60% thereof on 
the fifth such anniversary, provided that he is employed by the Company 
on such dates.  If Mr. Mandl's employment with the Company is terminated 
prior to September 3, 2001 by the Company other than for cause or by Mr. 
Mandl for good reason or by reason of his death or disability, the 
outstanding principal balance and accrued interest thereon will be 
forgiven; if his employment with the Company is terminated prior to 
September 3, 2001 for any other reason, the outstanding principal 
balance (and interest accrued thereof) will become immediately due and 
payable to MSI and DSC.

     Messrs. Pickle, Morris and Bell received loans each in the aggregate
principal amounts of $1,000,000. Such loans bear interest at annual
interest rates of 5.73%, 5.76% and 5.83%, respectively. The principal
amount and accrued interest on such loans will become due and payable
generally on February 1, 2000, April 10, 2000 and April 7, 2000,
respectively. Each of the loans provides for the forgiveness of the
principal balance and interest accrued thereon; generally, these
provisions become applicable either incrementally during the term of
the loan or as of its maturity date (in any case, subject to the
executive's continued employment with the Company as of such date) or,
among other things, in the event the executive's employment is terminated
under certain circumstances. In addition, each of the loans provides
that the remaining principal balance and interest accrued thereon will
become immediately due and payable in the event the executive's employment

                                  -13-


with the Company is terminated by the Company for cause or, generally, by
the executive other than by reason of death or disability.  Mr. Harris
received a loan in the aggregate principal amount of $600,000, bearing
interest at an annual rate of 6.54%.  Mr. Harris' loan is forgivable
only if he is terminated by the Company other than for cause, otherwise,
his loan is due and payable to the Company on June 8, 2000.  Mr. Harris
also received an upfront payment of $250,000, paid in January 1997.  At
the time Mr. Harris'options are exercised, the $250,000 will be deducted
from his option payout.

FirstMark Agreement
- -------------------
     Pursuant to the FirstMark Agreement, the Company granted the 
FirstMark Sole Stockholder certain registration rights with respect to 
the shares of Class A Common Stock into which the Firstmark Sole 
Stockholder's member interest in Teligent, L.L.C. will be converted 
pursuant to the Reorganization (the "FirstMark Sole Stockholder 
Registrable Securities"). Such registration rights include 
"piggyback" rights substantially similar to those granted to Mr. Mandl 
pursuant to the Mandl Employment Agreement.  Such "piggy-back" rights 
are subject to a customary underwriter's "cutback" whereby all shares of
Common Stock to be sold by the Company will first be included in the
applicable registration statement and thereafter all other shares requested
to be included in such registration statement will be subject to exclusion
on a pro rata basis. The FirstMark Sole Stockholder had no right to, and 
did not, sell any FirstMark Sole Stockholder Registrable Securities in
the Equity Offerings. Commencing on the first anniversary of the 
consummation of the Equity Offerings (November 26, 1998) the FirstMark 
Sole Stockholder is entitled under certain conditions, to one demand
registration under the Securities Act in respect of FirstMark Sole 
Stockholder Registrable Securities. In the FirstMark Agreement, the 
FirstMark Sole Stockholder has agreed not to engage, directly or indirectly,
in any business which provides or proposes to provide in the United States 
digital electronic message services in the 18 GHz frequency band or such 
other frequency band to which digital electronic message services are 
relocated by the FCC, or which provides fixed wireless voice, video or data 
transmission services in any frequency band in Canada.

Associated
- ----------
     Prior to the First Closing, Associated agreed to make the ACLA 
Contribution, and in consideration of such agreement received an 
approximate 1% increase in its member interest in Teligent, L.L.C. The 
Company has authorized a registration rights agreement with MSI whereby 
the Company will grant to MSI certain registration rights substantially 
similar to those granted to NTT (see "Certain Transactions-the 
Strategic Equity Investment- Registration Rights Agreement") and to DSC 
(see "Certain Relationships and Related Transactions-Members 
Agreement"). In addition, Associated provides certain general and 
administrative services to Teligent for a monthly fee of approximately 
$150,000. 

     Associated owns, operates and invests in a variety of 
communications activities and enterprises that may be in competition 
with the Company. There can be no assurance that Associated's current or 
future business activities will not be in competition with the Company's 
business.

NTT
- ---
     In connection with the NTT Purchase Agreement, the Company entered 
into the Technical Services Agreement with NTT America. See "Certain 
Transactions-The Strategic Equity Investment-Technical Services 
Agreement."
