3. ADMINISTRATION.

                  The Plan will be administered by the Board;  provided that the
Board may establish one or more Committees which may, to the extent set forth in
the  resolutions  establishing  such Committee or  Committees,  be authorized to
grant Awards to, and administer such Awards with respect to, those  Participants
who are subject to Section 16 of the  Exchange  Act with  respect to the Company
("Section 16  Participants") or who are executive  officers of the Company.  Any
such Committee that is authorized to grant Awards to Section 16  Participants (a
"Section 16 Committee") shall, to the extent necessary to comply with Rule 16b-3
promulgated  under the Exchange  Act, be comprised of two or more  "non-employee
directors"  within  the  meaning of such Rule,  and any such  Committee  that is
authorized  to grant Awards to executive  officers of the Company  (which may or
may not be the same Committee as the Section 16 Committee)  shall, to the extent
necessary to comply with Section 162(m) of the Code, be comprised of two or more
"outside directors" within the meaning of such Section. In the case of grants of
Awards to Participants  who are neither  Section 16  Participants  nor executive
officers of the Company, the Board in its discretion may delegate to a Committee
or to  members  of the  Company's  management  the  authority,  subject  to such
guidelines as the Board may approve from time to time and to ratification by the
Board,  to make grants of Awards to, and administer such Awards with respect to,
such Participants.  The Board shall have the authority,  in its sole discretion,
subject to and not  inconsistent  with the express  provisions  of the Plan,  to
administer  the  Plan  and to  exercise  all the  powers  and  authority  either
specifically  granted  to it  under  the  Plan  or  necessary  or  advisable  in
connection with the administration of the Plan,  including,  without limitation,
the authority to grant Awards;  to determine the persons to whom and the time or
times at which  Awards  shall be granted;  to  determine  the type and number of
Awards to be granted, the number of shares of Stock to which an Award may relate
and the terms, conditions, restrictions and performance criteria relating to any
Award; to determine  whether,  to what extent,  and under what  circumstances an
Award  may be  settled,  cancelled,  forfeited,  exchanged,  or  surrendered  or
accelerated or an Option or Options,  Stand-Alone SAR or Stand-Alone SARs may be
repriced to a lower exercise price; to make adjustments in performance  goals in
recognition  of  unusual  or  non-recurring  events  affecting  Teligent  or the
financial statements of Teligent,  or in response to changes in applicable laws,
regulations,  or accounting  principles;  to construe and interpret the Plan and
any Award; to prescribe, amend and rescind rules and regulations relating to the
Plan; to determine the terms and provisions of Award Agreements, consistent with
the  terms and  provisions  of the  Plan;  and to make all other  determinations
deemed  necessary or advisable for the  administration  of the Plan,  consistent
with the terms and  provisions of the Plan.  The Board shall keep minutes of its
meetings. To the extent that the Board has delegated any of its authority to one
or more Committees  under this Section 3, any reference to the Board in the Plan
shall be interpreted to mean reference to the relevant Committee.

4. ELIGIBILITY.

                  Awards may be granted to officers, other employees,  directors
and  consultants  of the  Company  in the  sole  discretion  of  the  Board.  In
determining  the persons to whom Awards  shall be granted and the type of Award,
the Board shall take into account such factors as the Board shall deem  relevant
in connection with accomplishing the purposes of the Plan.

5. STOCK SUBJECT TO THE PLAN; LIMITATION ON GRANTS.

                  The maximum number of shares of Stock  authorized and reserved
for issuance pursuant to the Plan shall be 18,729,125.  All such shares of Stock
shall be subject to equitable adjustment as provided herein. Such shares may, in
whole or in part,  be authorized  but unissued  shares or shares that shall have
been  or  may  be  reacquired  by  Teligent  in  the  open  market,  in  private
transactions  or  otherwise.  If any shares  subject to an Award are  forfeited,
cancelled,  exchanged or  surrendered  or if an Award  otherwise  terminates  or
expires without a distribution of shares to the Participant, the shares of Stock
with  respect  to such  Award  shall,  to the  extent  of any  such  forfeiture,
cancellation, exchange, surrender, termination or expiration, again be available
for Awards under the Plan. Upon the exercise of any Award granted in tandem with
any other  Awards,  such related  Awards shall be cancelled to the extent of the
number  of  shares   of  Stock  as  to  which  the  Award  is   exercised   and,
notwithstanding  the  foregoing,  such  number  of  shares  shall no  longer  be
available for Awards under the Plan.

                  During  the term of this  Plan,  no  Participant  can  receive
Awards,  including Options,  Restricted Stock and SARs (but excluding Conversion
Options),  relating  to shares of Stock  which in the  aggregate  exceed  twenty
percent  (20%) of the total  number of shares of Stock  authorized  for issuance
pursuant to the Plan, as adjusted pursuant to the terms hereof.

                  In the event that the Board shall  determine that any dividend
or other  distribution  (whether in the form of cash,  Stock or other property),
recapitalization,  stock split,  reverse  stock split,  reorganization,  merger,
consolidation,  spin-off,  combination,  repurchase, or share exchange, or other
similar  corporate  transaction  or  event,  affects  the  Stock  such  that  an
adjustment is  appropriate  in order to prevent  dilution or  enlargement of the
rights of Participants  under the Plan, then the Board shall make such equitable
changes or adjustments as it deems necessary or appropriate to any or all of (i)
the  number  and kind of  shares  of Stock  which  may  thereafter  be issued in
connection  with  Awards,  (ii) the number and kind of shares of Stock issued or
issuable in respect of outstanding  Awards,  and (iii) the exercise price, grant
price,  or purchase price relating to any Award;  provided that, with respect to
Incentive  Stock  Options,  such  adjustment  shall be made in  accordance  with
Section 424 of the Code.

6. STOCK OPTION AND SAR PROGRAM.

                  Each Option and SAR granted  pursuant to this  Section 6 shall
be evidenced by an Award  Agreement,  in such form and containing such terms and
conditions as the Board shall from time to time approve,  which Award  Agreement
shall  comply  with and be subject to the  following  terms and  conditions,  as
applicable. Each Conversion Option shall be governed by and subject to the terms
of the Plan, as well as the specific terms and provisions  previously determined
by the Board with respect thereto, which terms and provisions shall be set forth
in the Award Agreement evidencing such Conversion Option.

      (a) STOCK OPTIONS.

         (1) NUMBER OF SHARES.  Each Award  Agreement  shall state the number of
shares of Stock to which the Option relates.

         (2) TYPE OF OPTION.  Each Award  Agreement  shall state that the Option
constitutes an Incentive Stock Option or a Nonqualified Stock Option.

         (3) OPTION PRICE.  Each Award  Agreement  shall state the Option price,
which,  except for the  Conversion  Options and as  provided in Section  6(c)(2)
below,  shall not be less than one  hundred  percent  (100%) of the Fair  Market
Value of the shares of Stock  covered  by the  Option on the date of grant.  The
Option  price  shall be subject to  adjustment  as provided in Section 5 hereof.
Unless otherwise expressly stated in the Board resolution  expressly granting an
Option and except with  respect to Options  granted by members of the  Company's
management  pursuant to delegated  authority as contemplated by Section 3 of the
Plan, the date as of which the Board adopts the resolution expressly granting an
Option shall be considered the day on which such Option is granted.

         (4) METHOD AND TIME OF PAYMENT. The Option price shall be paid in full,
at the time of exercise,  in cash  (including  cash received from the Company as
compensation  or cash borrowed  from the  Company),  in shares of Stock having a
Fair Market Value equal to such Option price, in a combination of cash and Stock
or, in the sole discretion of the Board,  through a cashless exercise procedure,
which may include an exercise  through a  registered  broker-dealer  pursuant to
procedures  which are, from time to time,  deemed by the Board to be acceptable.
Any shares of Stock  withheld  upon  exercise as payment of the  purchase  price
under an  Option  shall be  valued  at their  Fair  Market  Value on the date of
exercise.

         (5) TERM AND  EXERCISABILITY  OF OPTIONS.  Each Award  Agreement  shall
provide that each Option shall become  exercisable  over a period  determined by
the Board in its discretion,  provided,  that the Board shall have the authority
to accelerate  the  exercisability  of any  outstanding  Option at such time and
under such circumstances as it, in its sole discretion,  deems appropriate.  The
exercise period shall be not more than ten (10) years from the date of the grant
of the Option,  except as provided in Section  6(c)(2)  below,  or such  shorter
period as is  determined by the Board.  The exercise  period shall be subject to
earlier  termination  as provided in Section  6(a)(6)  hereof.  An Option may be
exercised,  as to any or all full  shares  of Stock as to which the  Option  has
become  exercisable,  by written  notice  delivered  in person or by mail to the
Secretary of Teligent,  specifying the number of shares of Stock with respect to
which the Option is being exercised, together with payment in full of the Option
price.  For purposes of the  preceding  sentence,  the date of exercise  will be
deemed to be the date upon which the  Secretary  of Teligent  receives  both the
notification and the payment.

         (6) TERMINATION. The Agreement evidencing the grant of each Award shall
set forth the terms and  conditions  applicable to such Award upon a termination
of an employee  Participant's  employment by the Company or the termination of a
consultant or director Participant's service with the Company, which shall be as
the Board may, in its  discretion  determine at the time the Award is granted or
thereafter.

      (b) STOCK  APPRECIATION  RIGHTS.  The Board shall have  authority to grant
Stand-Alone  SARs,  and Tandem SARs with respect to all or some of the shares of
Stock covered by an Option.  Stand-Alone SARs granted pursuant to this Section 6
shall be evidenced by an Award  Agreement,  in such form as the Board shall from
time to time approve,  and the terms and  conditions of such Awards shall be set
forth therein. A Tandem SAR shall, except as provided in this Section (6)(b), be
subject to the same terms and conditions as the related Option.  Each Tandem SAR
granted  pursuant  to  the  Plan  shall  be  reflected  in the  Award  Agreement
evidencing the related Option.

         (1) TIME OF GRANT OF TANDEM SARS. A Tandem SAR may be granted either at
the time of grant,  or at any time  thereafter  during  the term of the  Option;
provided,  however, that Tandem SARs related to Incentive Stock Options may only
be granted at the time of grant of the related Option.

         (2) SAR  PRICE.  Each  Award  Agreement  shall  state  the  price for a
Stand-Alone  SAR, which shall not be less than one hundred percent (100%) of the
Fair Market Value of the shares of Stock covered by the  Stand-Alone  SAR on the
date of  grant.  The  price  for a Tandem  SAR  shall be set  forth in the Award
Agreement evidencing the related Option.

         (3) PAYMENT.  A SAR shall entitle the holder thereof,  upon exercise of
the SAR or any  portion  thereof,  to  receive  payment  of an  amount  computed
pursuant to paragraph (5) below.

         (4) EXERCISE.  Each Award Agreement shall provide that each Stand-Alone
SAR  shall  become  exercisable  over a period  determined  by the  Board in its
discretion,  provided, that the Board shall have the authority to accelerate the
exercisability of any Stand-Alone SAR at such time and under such  circumstances
as it, in its sole discretion,  deems appropriate.  The exercise period shall be
not more than ten (10) years from the date of the grant of the  Stand-Alone  SAR
or such shorter period as is determined by the Board.  The exercise period shall
be subject to earlier termination as provided in Section 6(b)(8) hereof.

             A Tandem SAR shall be exercisable at such time or times and only to
the extent that the related Option is exercisable,  and will not be transferable
except to the  extent the  related  Option  may be  -transferable.  A Tandem SAR
granted in connection with an Incentive  Stock Option shall be exercisable  only
if the Fair Market Value of a share of Stock on the date of exercise exceeds the
purchase price specified in the related Incentive Stock Option.

         (5) AMOUNT PAYABLE.  Upon the exercise of a SAR, the Participant  shall
be entitled to receive an amount determined by multiplying (i) the excess of the
Fair  Market  Value of a share of Stock on the date of exercise of such SAR over
the price of the  Stand-Alone SAR or the Option to which the Tandem SAR relates,
as  appropriate,  by (ii) the  number of shares of Stock as to which such SAR is
being  exercised.  Notwithstanding  the  foregoing,  the  Board may limit in any
manner the amount  payable with respect to any SAR by including  such a limit at
the time it is granted.

         (6) TREATMENT OF RELATED  OPTIONS AND TANDEM SARS UPON  EXERCISE.  Upon
the  exercise of a Tandem SAR,  the related  Option  shall be  cancelled  to the
extent of the number of shares of Stock as to which the Tandem SAR is  exercised
(and will be deemed to have been  exercised  for  purposes  of  determining  the
number of shares available for the grant of Awards under the Plan), and upon the
exercise of an Option  granted in  connection  with a Tandem SAR, the Tandem SAR
shall be  cancelled  to the  extent of the number of shares of Stock as to which
the Option is exercised  (and will be deemed to have been exercised for purposes
of determining the number of shares  available for the grant of Awards under the
Plan).

         (7) METHOD OF EXERCISE.  SARs shall be exercised by a Participant  only
by a written  notice  delivered in person or by mail to the Company,  Attention:
Senior Vice President for Human Resources, specifying the number of whole shares
of Stock with respect to which the SAR is being  exercised.  If requested by the
Board, the Participant shall deliver the Award Agreement evidencing the SAR and,
if applicable,  the related Option, which Award Agreement shall be endorsed with
a notation of such  exercise  and returned to the  Participant.  For purposes of
this  paragraph  (7),  the date of  exercise  will be deemed to be the date upon
which the Company receives such notification.

         (8) FORM OF PAYMENT.  Payment of the amount  determined under paragraph
(5) above may,  in the sole  discretion  of the Board,  be made  solely in whole
shares of Stock in a number determined based upon their Fair Market Value on the
date of exercise of the SAR or,  alternatively,  in the sole  discretion  of the
Board,  solely in cash, or in a  combination  of cash and shares of Stock as the
Board deems  advisable.  If the Board determines that payment may be made solely
in shares of Stock,  and the  amount  payable  results  in a  fractional  share,
payment for the fractional share will be made in cash.

      (c) INCENTIVE  STOCK OPTIONS.  Options  granted as Incentive Stock Options
shall be subject to the following  special terms and conditions,  in addition to
the general terms and conditions specified in this Section 6.

         (1) VALUE OF SHARES.  The aggregate Fair Market Value (determined as of
the date the  Incentive  Stock  Option is  granted)  of the shares of Stock with
respect to which  Incentive  Stock Options granted under this Plan and all other
Plans of the Company become  exercisable for the first time by each  Participant
during any calendar year shall not exceed $100,000.

         (2) TEN PERCENT  STOCKHOLDER.  In the case of an Incentive Stock Option
granted to a Ten  Percent  Stockholder,  (x) the Option  price shall not be less
than one hundred ten  percent  (110%) of the Fair Market  Value of the shares of
Stock on the date of grant of such Incentive Stock Option,  and (y) the exercise
period shall not exceed five (5) years from the date of grant of such  Incentive
Stock Option.

7. RESTRICTED STOCK AWARD PROGRAM.

                  Restricted  Stock  Awards  granted  pursuant to this Section 7
shall be evidenced by an Award  Agreement,  in such form as the Board shall from
time to time approve,  and the terms and  conditions of such Awards shall be set
forth therein.  At the time of the grant of a Restricted  Stock Award, the Board
may impose such  restrictions  or conditions to the vesting of such Award as it,
in its sole  discretion,  deems  appropriate.  Such  conditions  to vesting  may
include (without limitation), in the Board's sole discretion, the achievement of
performance  goals  which  may  be  set  forth  in  the  Award  Agreement.  Such
performance  goals  may  (without  limitation)  be based on an  increase  in the
trading  price of Stock,  achievement  of certain  goals  relating to Teligent's
return on assets, return on equity, earnings per share, in each case, determined
in accordance with generally accepted accounting principles.

      (a)  RESTRICTIONS.  Prior to the vesting of a share of  Restricted  Stock,
such share of Restricted Stock may not be sold, assigned, transferred,  pledged,
hypothecated or otherwise disposed of, except by will or the laws of descent and
distribution.  Certificates  for shares of Stock which may be issued pursuant to
Restricted  Stock  Awards  shall bear an  appropriate  legend  referring to such
restrictions,  and any  attempt  to  dispose  of any  such  shares  of  Stock in
contravention of such restrictions shall be null and void and without effect.

      (b)  FORFEITURE.  Subject to such  exceptions  as may be determined by the
Board, if an employee Participant's continuous employment with the Company shall
terminate for any reason, or if a consultant or director  Participant's  service
with the Company shall terminate for any reason, any shares remaining subject to
restrictions shall thereupon be forfeited by the Participant and transferred to,
and reacquired by, Teligent at no cost to Teligent.

      (c)  OWNERSHIP.  Except  to the  extent  otherwise  set forth in the Award
Agreement,  a Participant who is granted a Restricted  Stock Award shall possess
all incidents of ownership of such shares,  subject to Section  7(a),  including
the right to receive  dividends  with  respect  to such  shares and to vote such
shares.

8. GENERAL PROVISIONS.

      (a)  COMPLIANCE  WITH LEGAL  REQUIREMENTS.  The Plan and the  granting and
exercising of Awards,  and the other  obligations of Teligent under the Plan and
any Award  Agreement  or other  agreement  shall be  subject  to all  applicable
federal and state  laws,  rules and  regulations  and to such  approvals  by any
regulatory  or  governmental  agency  as  may  be  required.  Teligent,  in  its
discretion,  may  postpone  the issuance or delivery of Stock under any Award as
Teligent may consider  appropriate  and may require any Participant to make such
representations  and furnish such information as it may consider  appropriate in
connection  with the issuance or delivery of Stock in compliance with applicable
laws, rules and regulations.

      (b) NONTRANSFERABILITY.  Awards shall not be transferable by a Participant
other than (i)  gratuitous  transfers  by an officer of the  Company  who is the
holder of an Award to his or her immediate  family members or to a trust for the
benefit of any such immediate family member or members, (ii) by will or the laws
of descent and  distribution or, (iii) if then permitted by Rule 16b-3 under the
Exchange Act, pursuant to a Qualified Domestic Relations Order (as defined under
the Code or Title I of the Employee  Retirement  Income Security Act of 1974, as
amended,  or the rules  thereunder).  Awards  shall be  exercisable  during  the
lifetime of a  Participant  only by such  Participant  or his  guardian or legal
representative.

      (c) NO RIGHT TO CONTINUED EMPLOYMENT.  Nothing in the Plan or in any Award
granted or any Award Agreement or other  agreement  entered into pursuant hereto
shall  confer  upon any  Participant  the right to continue in the employ of the
Company or to continue  service as a consultant or director of the Company or to
be entitled to any  remuneration  or benefits  not set forth in the Plan or such
Award  Agreement or other agreement or to interfere with or limit in any way the
right of the Company to terminate such employee Participant's  employment or the
service of a consultant or director Participant.

      (d) WITHHOLDING  TAXES. Where a Participant or other person is entitled to
receive  shares of Stock  pursuant to the  exercise of an Option or is otherwise
entitled  to receive  shares of Stock or cash  pursuant  to an Award  hereunder,
Teligent shall have the right to require the Participant or such other person to
pay to  Teligent  the amount of any taxes  which  Teligent  may be  required  to
withhold  before  delivery  to such  Participant  or other  person  of cash or a
certificate or certificates representing such shares.

          If a Participant  makes a  disposition,  within the meaning of Section
424(c)  of the Code and  regulations  promulgated  thereunder,  of any  share or
shares of Stock  issued  to such  Participant  pursuant  to the  exercise  of an
Incentive Stock Option within the two-year  period  commencing on the date after
the date of the grant or within the one-year period  commencing on the day after
the date of  transfer  of such  share  or  shares  of  Stock to the  Participant
pursuant to such exercise,  the Participant shall,  within ten (10) days of such
disposition,  notify the  Company  thereof,  by  delivery  of written  notice to
Teligent at its principal executive office.

          Unless  otherwise  prohibited  by the Board or by  applicable  law,  a
Participant  may  satisfy  any such  withholding  tax  obligation  by any of the
following  methods,  or by a combination  of such methods:  (a) tendering a cash
payment;  (b) authorizing  Teligent to withhold from the shares of Stock or cash
otherwise  payable to such  Participant (1) one or more of such shares having an
aggregate  Fair Market  Value,  determined  as of the date the  withholding  tax
obligation arises, less than or equal to the amount of the total withholding tax
obligation  or (2) cash in an  amount  less  than or equal to the  amount of the
total  withholding  tax  obligation;  or (c)  delivering to Teligent  previously
acquired  shares of Stock  (none of which  shares  may be  subject to any claim,
lien,  security interest,  community property right or other right of spouses or
present or former family  members,  pledge,  option,  voting  agreement or other
restriction or encumbrance  of any nature  whatsoever)  having an aggregate Fair
Market Value,  determined as of the date the withholding tax obligation  arises,
less than or equal to the amount of the total withholding tax obligation.

      (e) AMENDMENT AND  TERMINATION  OF THE PLAN. The Board may at any time and
from time to time alter,  amend,  suspend,  or terminate the Plan in whole or in
part;  provided  that, no amendment  which requires  stockholder  approval under
applicable  law in order for the Plan to continue to comply with  Section 422 or
162(m) of the Code or in order for the Plan to continue to comply with the rules
and  regulations  of any exchange or other  trading  market on which  Teligent's
shares of Stock are traded shall be effective  unless the same shall be approved
by the  requisite  vote of the  stockholders  of Teligent.  Notwithstanding  the
foregoing,  no  amendment  shall  affect  adversely  any  of the  rights  of any
Participant,  without such  Participant's  consent,  under any Award theretofore
granted  under  the  Plan.  The  power  to grant  Awards  under  the  Plan  will
automatically  terminate  at the end of the  2007  fiscal  year.  If the Plan is
terminated,  any  unexercised  Option or SAR shall continue to be exercisable in
accordance with its terms and the terms of the Plan in effect  immediately prior
to such termination.

      (f) CHANGE IN CONTROL.  Notwithstanding any other provision of the Plan to
the contrary,  if, while any Awards remain  outstanding under the Plan, a Change
in Control of Teligent  (as defined in this  Section  8(f))  shall  occur,  then
(unless otherwise  provided in the applicable Award Agreement),  (x) all Options
and SARs that are outstanding at the time of such Change in Control shall become
immediately  exercisable in full and (y) all restrictions with respect to shares
of  Restricted  Stock shall  lapse,  and such shares  shall be fully  vested and
nonforfeitable.

          For purposes of this paragraph 8(f), a "Change in Control" of Teligent
shall occur if :

         (1) any person or entity,  or group of affiliated  persons or entities,
other than The Associated Group,  Inc., a Delaware  corporation,  and Telcom-DTS
Investors,  L.L.C.,  a Delaware limited  liability  company  (collectively,  the
"Original  Shareholders")  and/or their respective  affiliates acquires stock of
the Company  representing  more than fifty  percent (50%) of the voting power of
all such outstanding stock;

         (2) the majority of the Board  consists of persons who are designees of
any person or entity or group of affiliated persons or entities which hold stock
in the Company,  other than the Original  Shareholders  and/or their  respective
affiliates;

         (3)  the  Company  adopts  a plan  of  liquidation  providing  for the
distribution of all or substantially all of its assets; or

         (4) all or substantially all of the business  enterprise of the Company
is  disposed  of  pursuant  to  a  sale  of  assets  transaction  or  a  merger,
consolidation  or similar  transaction in which the Company is not the surviving
entity  (unless  (A) no person or  entity,  or group of  affiliated  persons  or
entities,   other  than  the  Original   Shareholders  and/or  their  respective
affiliates,  owns  immediately  after  such  transaction  stock or other  equity
interests  of the entity  which  succeeds  to the  business  of the Company as a
result of such  transaction  representing  more than fifty  percent (50%) of the
voting  power of all such  outstanding  stock,  (B) a  majority  of the board of
directors (or  comparable  governing  body) of the entity which  succeeds to the
business of the Company as a result of such transaction  consists of persons (or
persons  designated  by such  persons) who  constituted  a majority of the Board
immediately prior to such transaction,  and (C) such successor entity assumes in
writing  the  Company's  obligations  under  the  Plan.  For  purposes  of  this
definition,  "affiliate" (or derivations  thereof) of any person or entity means
any other person or entity  directly or indirectly  controlling or controlled by
or under direct or indirect  common control with such person or entity;  and for
purposes of such  definition,  "control" when used with respect to any person or
entity means the power to direct the  management  and policies of such person or
entity,  directly  or  indirectly,  whether  through  the  ownership  of  voting
securities or other equity  interests,  by contract or otherwise,  and the terms
"controlling" and "controlled" have meanings correlative to the foregoing.

      (g) PARTICIPANT  RIGHTS. No Participant shall have any claim to be granted
any Award under the Plan, and there is no obligation for uniformity of treatment
for  Participants.  Except as provided  specifically  herein, a Participant or a
transferee of an Award shall have no rights as a stockholder with respect to any
shares of stock  covered by any Award until the date of the  issuance of a Stock
certificate to him for such shares.

      (h)  UNFUNDED  STATUS OF AWARDS.  The Plan is  intended to  constitute  an
"unfunded"  plan for  incentive and deferred  compensation.  With respect to any
payments not yet made to a Participant  pursuant to an Award,  nothing contained
in the Plan or any Award  shall give any such  Participant  any rights  that are
greater than those of a general creditor of Teligent.

      (i) NO FRACTIONAL SHARES. No fractional shares of Stock shall be issued or
delivered  pursuant to the Plan or any Award. The Board shall determine  whether
cash,  other  Awards or other  property  shall be issued or paid in lieu of such
fractional  shares or whether such fractional shares or any rights thereto shall
be forfeited or otherwise eliminated.

      (j) GOVERNING LAW. The Plan and all determinations  made and actions taken
pursuant  hereto shall be governed by the laws of the State of Delaware  without
giving effect to the conflict of laws principles thereof.

      (k) EFFECTIVE DATE. The Plan has previously been approved by the Board and
Teligent's sole  stockholder.  The Plan shall become  effective on the effective
date of the Initial  Offering (the "Effective  Date"),  and shall be of no force
and effect if the Initial Offering is not consummated.

      (l)  BENEFICIARY.  A  Participant  may  file  with  the  Board  a  written
designation  of a beneficiary on such form as may be prescribed by the Board and
may,  from time to time,  amend or revoke  such  designation.  If no  designated
beneficiary  survives  the  Participant,  the executor or  administrator  of the
Participant's estate shall be deemed to be the grantee's beneficiary.


      (m)  INTERPRETATION.  The Plan is  designed  and  intended  to comply with
Section 162(m) of the Code,  and all  provisions  hereof shall be construed in a
manner to so comply.
