     This Form 10-K/A is being filed in order to amend the Items set forth below
so as to respond to certain comments the Company received from the SEC on its
original Form 10-K for the year ended December 31, 2000 (the "Original 10-K").
In reviewing the Form 10-K/A and the Original 10-K, the reader should be aware
that since the filing of the Original 10-K the Company and all of its domestic
subsidiaries have filed voluntary bankruptcy petitions under Chapter 11 of the
U.S. Bankruptcy Code (see the Company's Form 8-K dated May 21, 2001) and there
have been substantial changes in the Company's stock ownership, Board of
Directors and management. The information contained in the Form 10-K/A under
Part II, Item 7 (Management's Discussion and Analysis of Financial Condition and
Results of Operations) has not been updated to reflect financial changes,
including the bankruptcy filings, since the filing of the Original 10-K. The
information contained under Part IV of the Form 10-K/A has been revised from
that contained in the Original 10-K to reflect the classification of the
Company's debt as current.

     Except for any historical information contained herein, the matters
discussed in this Form 10-K contain certain "forward-looking statements" within
the meaning of the Private Securities Litigation Reform Act of 1995 with respect
to the Company's financial condition, results of operation and business. The
words "anticipate," "believe," "estimate," "expect," "plan," "intend" and
similar expressions, as they relate to the Company, are intended to identify
forward-looking statements. Such statements reflect our current views with
respect to future events and involve known and unknown risks, uncertainties and
other factors. The Company cannot be sure that any of its expectations will be
realized.

     In this Annual Report on Form 10-K/A, we will refer to Teligent, Inc., a
Delaware corporation, and, as appropriate, its subsidiaries, as "Teligent," "the
Company," "we," "us," and "our." Where applicable, such references refer to
Teligent's limited liability company predecessor.

ITEM 6.   SELECTED FINANCIAL DATA

     The selected financial data presented below as of December 31, 2000, 1999,

(1)  Certain amounts in the prior periods' financial statements have been
     reclassified to conform to the current year's presentation.

(2)  EBITDA consists of earnings before interest, taxes, depreciation,
     amortization, stock-based and other non-cash compensation charges and
     restructuring and asset impairment charges. While not a measure under
     generally accepted accounting principles ("GAAP"), EBITDA is a measure
     commonly used in the telecommunications industry, and we include it to help
     you understand our operating results. Although you should not assume that
     EBITDA is a substitute for operating income determined in accordance with
     GAAP, we present it to provide additional information about our ability to
     meet future debt service, capital expenditures and working capital
     requirements. See the Financial Statements and the related notes. Since all
     companies and analysts do not calculate these non-GAAP measurements the
     same way, the amount may not be comparable to other calculations.

(3)  The December 31, 2000 consolidated balance sheet has been restated to
     classify the Company's outstanding debt to a current liability.

ITEM 7.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS

     Certain statements set forth below under this caption constitute
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Please refer to page 3 of the Original 10-K for
additional factors relating to such statements.

GENERAL

     The following discussion and analysis is based on Teligent's financial
statements for the years ended December 31, 1998 through 2000 and should be read
together with the Financial Statements and related notes contained elsewhere in
this Annual Report on Form 10-K.

FACTORS AFFECTING FUTURE OPERATIONS

     The execution of our business plan has resulted in the rapid expansion of
our operations. This expansion of our operations, including our international
operations, has created operating losses and negative cash flow since our
inception, and may continue to place a significant strain on our management,
financial condition and other resources. Our ability to manage this expansion
effectively will depend upon, among other things, raising capital to pay
expenses, monitoring operations, controlling costs, maintaining regulatory
compliance, interconnecting successfully with the incumbent telephone companies,
maintaining effective quality controls, securing building access, significantly
expanding our internal management, technical, information and accounting systems
and attracting, assimilating and retaining qualified management and professional
and technical personnel. If we are unable to hire and retain senior management
and key staff, expand our facilities, purchase adequate supplies of equipment,
secure building access, increase the capacity of our information systems and/or
successfully manage and integrate such additional resources, customers could
experience delays in connection of service and/or lower levels of customer
service. Failure to meet the demands of customers and to manage the expansion of
our business and operations could have a material adverse effect on our
business, financial condition and results of operations.



                                       3
   4

     As of March 26, 2001, we had approximately $194 million of cash, cash
equivalents and short-term investments, which based on internal projections, is
expected to allow us to remain funded through the second quarter of 2001. Our
credit facility, entered into on July 2, 1998, has been fully drawn down. Thus,
we need additional sources of funding to finance our operations starting in the
third quarter.

     We will require significant capital to, among other things, finance the
further development and expansion of our business and deployment of our
services, including purchasing and installing equipment, operating our network,
obtaining additional spectrum licenses, investing in our international expansion
and joint ventures, leasing office space, hiring and retaining employees,
funding operating losses and for working capital and debt service purposes.
Based on our current business plan, we expect to incur between $220 million and
$250 million in capital investments in the year 2001.

     As of March 26, 2001, we had outstanding $300 million aggregate principal
amount of 11.5% Senior Notes due 2007, $440 million aggregate principal amount
of 11.5% Senior Discount Notes due 2008, and $800 million under our existing
credit facility. These debt instruments impose significant operating and
financial restrictions on us, including certain limitations on our ability to
incur additional debt, pay dividends, redeem capital stock, sell assets, engage
in mergers and acquisitions or make investments, transact with affiliates, sell
stock of subsidiaries and place liens on our assets. In addition, our credit
facility contains certain covenants, including covenants regarding the
achievement of certain financing and performance targets and the maintenance of
certain financial ratios.

     We received a waiver of the fixed charge coverage ratio for the period
ending December 31, 2000 from the lenders as a part of an amendment and consent
to our existing credit facility. We were in compliance with all other debt
covenants of the existing credit facility as of December 31, 2000. As part of
the amendment, we are required to deliver definitive documentation with respect
to vendor financing (in an aggregate amount of at least $250 million) and
convertible notes (in an aggregate amount of at least $100 million), no later
than April 30, 2001. There can be no assurance that the Company can obtain
vendor financing or convertible notes as required by the amended credit
facility. Failure to observe or perform one or more of the covenants at any
given time will require us to obtain a waiver or consent from the lenders, or
refinance our credit facility. Such a waiver, consent or refinancing may not be
available to us on reasonable terms. A breach of these covenants, ratios or
restrictions in our credit facility also could result in an event of default.
Upon the occurrence of an event of default under our credit facility, the
lenders could elect to declare all amounts outstanding under our credit
facility, together with our accrued interest, to be immediately due and payable.
Our failure to comply with any of these covenants or restrictions could also
limit our ability to obtain future financings. The Company has restated its
December 31, 2000 consolidated balance sheet to classify the outstanding debt to
a current liability.

   Revenues

     We offer an integrated package of local and long distance services,
value-added services, high-speed data connectivity and Internet access. We
market these services primarily to businesses within buildings on our network
that have been historically served by incumbent telephone companies. We seek to
attract these customers through a broad product offering, superior customer
service and attractive pricing. We anticipate that some of these incumbent
telephone companies may reduce their prices as increased competition begins to
reduce their market share.

   Cost of Services

     Certain costs are required to operate and maintain our networks, including:

          -    Real estate leases for switching centers, base station and
               customer buildings;

          -    Preparation, installation, operation and maintenance of switching
               centers, base station sites and individual customer radio links,
               as well as equipment in customer buildings;

          -    Leasing of backhaul facilities between base station sites and
               switching centers;

          -    Leasing of capacity lines;

          -    Network operations and data center facility expenses;

          -    The cost to interconnect and terminate traffic with other network
               and internet service providers;

          -    Software licensing fees; and

          -    And network design and base station configuration planning.

   Sales, General and Administrative Costs

     We incur costs related to the selling, marketing and promotion of our
products and services. These costs primarily include headcount costs for our
sales and other personnel, as well as advertising costs to develop brand
awareness of the Teligent name.

     We also incur operating costs that are common to all telecommunications
providers including customer service and technical support, information systems,
billing and collections, general management and overhead expense, office leases,
bad debt expense and administrative functions. Those areas that will require
more personnel as our customer base grows, such as customer service, will
increase gradually as customer demand increases. Other areas, particularly
information and billing systems, have required significant up-front capital
expenditures and operating costs.

   Capital Expenditures

     Our main capital expenditure requirements currently include the purchase
and installation of equipment in customer buildings, base stations, network
switches, switch electronics, optical fiber transport equipment, network
operations center tools and systems, data centers equipment and information
technology systems.

     Equipment in Customer Buildings. The purchase and installation of equipment
in customer buildings is the largest single capital expense component in our
business plan. These equipment costs include an integrated radio/antenna unit,
modem(s), power supply, multiplexer and router equipment, DSL equipment, line
interface cards, and cables and installation materials. Customers in the same
building may share portions of this equipment, which reduces the capital
expenditures required per customer. In the event a customer leaves us, our
equipment can be used by other customers within the building or in other
buildings, which reduces stranded assets.

     Base Station Site. A base station can serve customers within a coverage
area of up to 360-degrees, subject to line-of-sight limitations. A base station
typically comprises four to eight sectors, each of which cover a section of the
service area depending on coverage and capacity requirements. Each sector
requires one or more radio/antenna units and modems, depending on the system
deployed. Construction costs per base station are typically higher than
construction costs per building site. We expect that our sites will typically be
built on top of buildings as opposed to located on towers. While a certain
amount of equipment must initially be installed at each base station, the
overall equipment cost will depend on the number of customers acquired. As more
customers are loaded onto a given base station area, we will add additional
sectors, radio antennas and modems to the initial base station equipment to meet
customer demand.

     Base Station to Switch Transport. We transport traffic between our base
stations and switching sites. To the extent we use wireless transport rather
than leased fiber, we would incur capital expenditures as opposed to operating
costs. We also plan to acquire and deploy equipment necessary to activate and
use leased dark fiber.

     Switching. Switching costs include traditional circuit-based switch
modules, line cards for interfacing with the backhaul networks and with the
networks of other carriers, packet-based routers, power systems, and
environmental maintenance equipment.



                                       5
   6

     Network Operations Center. Network operation center costs include
investments in developing a command, control and communications center to
monitor and manage our entire network infrastructure. Further costs include
investments in applications and commercial hardware and software solutions
customized for problem identification and network monitoring.

     Data Centers. Data centers are specifically designed for the 24-hour a day
routing of Internet traffic and hosting of Web sites and e-mail. Costs to
develop data centers include investments in computer hardware and software,
redundancy equipment, utilities and environmental controls, security systems,
and broadband connectivity.

     Information Technology. Costs to acquire, develop and enhance information
technology systems will also require significant capital investment. Systems for
billing, customer services, order entry and management, finance and network
provisioning and monitoring, among others, have been or are under development or
further enhancement.

COSTS OF OBTAINING ADDITIONAL SPECTRUM

     Our existing spectrum has been obtained through means other than
competitive bidding procedures. In the future, additional spectrum may be
obtained in the United States and abroad through acquisitions and auctions.
Additionally, Teligent International, Ltd. has obtained spectrum in
international markets through an award process. Such awards are based on the
quality of the application and the capabilities of the applicants, relative to
the requirements of the regulatory bodies within a particular country.

RESULTS OF OPERATIONS

   YEAR ENDED DECEMBER 31, 2000 COMPARED TO YEAR ENDED DECEMBER 31, 1999

     Teligent's revenues from communication services grew by $120.8 million, or
386%, to $152.1 million during 2000, compared to $31.3 million during 1999. The
increase in revenues is due to growth in our customer base, revenue from
acquisitions and expansion into new markets.

     Revenue, exclusive of revenues from entities acquired during 2000,
increased by $80.3 million, or 257%, to $111.6 million for the year ended
December 31, 2000, compared to the corresponding prior year period. This growth
is due to an increase in customers served by a greater number of service lines
in existing market areas and expansion into new markets throughout 1999 and
2000. As of December 31, 2000, Teligent served approximately 35,500 customers,
compared to approximately 15,000 customers at December 31, 1999. Additionally,
Teligent had approximately 490,000 lines in service, compared to approximately
228,000 as of December 31, 1999. These lines may be provisioned for local, long
distance or data service or a combination thereof. Revenues from entities
acquired during 2000 totaled $40.5 million for the year ended December 31, 2000.
Our revenues are comprised of the following (amounts in thousands):

                                        =========       ========


     -    Local service revenues increased by $26.7 million, or 443%, for the
          year ended December 31, 2000, compared to the corresponding prior year
          period. This increase is due to a greater volume of customers ordering
          local service over an increased number of local service lines in our
          network. Customers ordering local service increased by 165% to
          approximately 8,500 as of December 31, 2000, up from 3,200 as of
          December 31, 1999. Total local lines increased by 306% to
          approximately 138,000 as of December 31, 2000, up from approximately
          34,000 as compared to the corresponding prior year period.

     -    Long distance service revenues increased by $53.7 million, or 276%,
          for the year ended December 31, 2000, compared to the corresponding
          prior year period. This increase is primarily due to additional
          customers ordering long distance service over our increased number of
          long distance service lines. Customers ordering



                                       6

          long distance service increased by 141% to approximately 34,500 as of
          December 31, 2000, up from 14,300 as of December 31, 1999. Total long
          distance service lines increased by 89% to approximately 413,000 as of
          December 31, 2000, up from approximately 219,000 as compared to the
          corresponding prior year period.

     -    Data and other service revenues increased by $40.4 million, or 697%,
          for the year ended December 31, 2000, compared to the corresponding
          prior year period. The increase is due to revenue from acquisitions
          and higher number of customers ordering data services over an
          increased number of data lines in our network.

     Cost of services, consisting primarily of telecommunications expenses,
operating personnel costs and site acquisition and rent expenses, increased by
$117.6 million, or 57%, to $325.1 million from $207.5 million for the year ended
December 31, 2000, as compared to the corresponding prior year period. This
increase is primarily due to the costs of provisioning higher volumes of
telecommunications and data traffic over our networks. Increases in
personnel-related costs, site rent and utility expenses and office rent related
to our expansion into new markets during 1999 and 2000 also contributed to the
increase in cost of services for these periods. Additionally, telecommunication
costs were reduced by $39.7 million for the year ended December 31, 2000 related
to the resolution of an outstanding liability with one of our vendors. The
Company completed a settlement with the vendor in September 2000 that resulted
in the payment of $17.3 million in interest to the vendor and reimbursement by
the vendor to the Company in the amount of $55 million. Of this amount, $39.7
million was for equipment costs, telecommunication costs, and other network
costs for multipoint radio equipment that did not perform to design
specifications. The $39.7 million was recorded as a reduction of
telecommunications costs which were incurred prior to the completion of the
equipment upgrades. The remaining $15.8 million of the reimbursement from the
vendor was applied against a receivable from the vendor and towards a reserve
for fixed assets associated with the assets to be taken out of service.

     Sales, general and administrative expenses increased by $57.2 million, or
28%, to $262.8 million from $205.6 million for the year ended December 31, 2000,
as compared to the corresponding prior year period. This increase is primarily
attributable to the hiring of additional employees during the second half of
1999 and first half of 2000 to support the expansion of our business through
additional markets and services.

     Restructuring and asset impairment totaled $34.6 million for the year ended
December 31, 2000. One-time restructuring charges totaled $14.5 million and
include $6.8 million for severance and other compensation, $5.8 million for net
costs relating to lease terminations, and other costs of $1.9 million. Severance
and other compensation relates to the workforce reduction which occurred in
November 2000, and resulted in the termination of approximately 600 employees,
primarily in the sales, real estate, and network operations areas. A non-cash
charge of $20.1 million was recorded to reflect the impairment of fixed assets
in markets in which we are planning to reduce services under the restructuring
plan. The asset impairment charge was calculated based on 100% of the net book
value of the assets located in these markets.

     Stock-based and other non-cash compensation expense decreased by $3.1
million, or 10%, to $28.4 million from $31.5 million for the year ended December
31, 2000, as compared to the corresponding prior year period. These expenses
relate to compensation earned by certain employees and executives at the time of
the initial public offering that are being recognized over specified vesting
periods. No additional grants have been made to these persons since the date of
the initial public offering.

     Depreciation and amortization increased by $87.8 million, or 192%, to
$133.5 million from $45.7 million, for the year ended December 31, 2000, as
compared to the corresponding prior year period. This increase is due to
significant capital expenditures made during 1999 and 2000 for property,
equipment and acquisitions. The Company also charged $31.1 million to
depreciation and amortization in 2000 for the write down of certain undeployed
assets, where it was determined that such assets would not be deployed.

     Interest income increased by $6.1 million, or 32%, to $25.0 million from
$18.9 million, for the year ended December 31, 2000, as compared to the
corresponding prior year period. This increase is due to higher average cash and
cash equivalent balances in 2000 resulting from the proceeds received from the
November 1999 Series A Preferred Stock and April 2000 Class A common stock
offerings, draw downs made on the credit facility and higher average interest
rates during 2000.



                                       7
   8

     Interest expense increased by $45.0 million, or 51%, to $133.3 million from
$88.3 million, for the year ended December 31, 2000, as compared to the
corresponding prior year period. The increase is due to higher long-term debt
balances. Additionally, the Company recorded $17.3 million in interest expense
during the third quarter of 2000 related to the resolution of an outstanding
liability with one of our vendors.

     Equity in losses of international ventures totaled $6.6 million for the
year ended December 31, 2000. These losses are the Company's share of losses
incurred on its investments in international ventures.

     Other expense increased by $60.3 million to $60.8 million from $500,000 for
the year ended December 31, 2000, as compared to the corresponding prior year
period. This increase is due to a $61.6 million loss on the write down of
available-for-sale securities to their fair value.

   YEAR ENDED DECEMBER 31, 1999 COMPARED TO YEAR ENDED DECEMBER 31, 1998

     We generated revenues of $31.3 million from communication services during
1999, compared to $1.0 million during 1998. The increase in revenues is
reflective of, among other things, the growth in our customer base, continued
expansion into new market areas during 1999 and revenue attributable to
acquisitions.

     Cost of services, consisting primarily of personnel-related costs,
telecommunications expenses and site rent and site acquisition expenses related
to network operations, totaled $207.5 million for 1999, compared to $79.3
million in 1998. This increase reflects the growth and development of our
network operations to serve 40 major market areas and the increased number of
employees from 1998 to 1999.

     Sales, general and administrative expenses, consisting primarily of
personnel-related costs, were $205.6 million for 1999, compared to $124.0
million in 1998. This increase primarily results from higher compensation and
other personnel costs incurred during 1999 due to the increased number of
employees required to drive our growth.

     Stock-based and other non-cash compensation expense was $31.5 million in
1999, compared to $32.2 million in 1998.

     Depreciation and amortization for 1999 was $45.7 million, compared to $14.2
million in 1998. The increase is due to higher capital expenditures in 1999 and
the amortization of goodwill associated with acquisitions.

     Interest income for 1999 was $18.9 million, compared to $34.5 million in
1998. The decrease is due to lower average cash and cash equivalent balances.

     Interest expense was $88.3 million in 1999, compared to $66.9 million in
1998. The increase is due to higher long-term debt balances resulting from
borrowings made against the credit facility during 1999 and the amortization of
credit facility fees and interest incurred on the 11 1/2% Senior Discount Notes.

     Other expense was $500,000 in 1999, compared to $400,000 in 1998. These
amounts are due to losses from the disposal of property and equipment.


LIQUIDITY AND CAPITAL RESOURCES

     We have approximately $194 million of cash, cash equivalents and short-term
investments as of March 26, 2001. Based on our internal projections, we expect
this amount will allow us to remain funded through the second quarter of 2001.
Our credit facility, entered into on July 2, 1998, has been fully drawn down.
Thus, we need additional sources of funding to finance our operations starting
in the third quarter. In addition, in order to develop our business, we will
need a significant amount of money to pay for equipment, meet our debt
obligations, operate our business on a day-to-day basis and contribute
additional capital to our international ventures. Our principal
equipment-related needs include the purchase and installation of equipment in
customer buildings, base stations, network switches and switch electronics,
network operations and data center expenditures and information systems,
platforms and interfaces. We are exploring a variety of alternatives that may
provide the necessary financing, including equity, debt and vendor financing.



                                       8
   9

     We plan to supplement these funds with proceeds, if available, of up to
$250 million in connection with a stock purchase agreement dated December 7,
2000. (See "Liquidity and Capital Resources--Stock Purchase Agreement") Were we
to gain access to all $250 million in 2001, our projections indicate that we
would be funded through 2001. These projections may be materially different than
the actual timing and amount of money required for the development of our
business and to fund net operating expenses. The stock purchase agreement is
contingent upon certain conditions that we currently do not meet, and there can
be no assurance that we will be able to obtain all or any part of the $250
million equity financing, when such financing will be available or that we will
be able to obtain any other additional financing on terms acceptable to us.

     On February 15, 2001, we announced a workforce reduction associated with
the continuing efforts to realign our sales operations. As a result of this
reduction, we terminated 172 employees company-wide and expect to record a
charge of approximately $600,000 in the quarter ended March 31, 2001. We will
continue to evaluate our capital requirements as it relates to personnel-related
expenses. We are managing operations with reduced headcount-related and other
operating expenses and monitoring our on-going capital requirements.

   Credit facility and vendor financing

     On July 2, 1998, we entered into a credit agreement, as subsequently
amended, with The Chase Manhattan Bank, Goldman Sachs Credit Partners, and
Toronto Dominion Bank, and other lenders, providing for credit facility up to an
aggregate of $800 million. Our obligations under the credit agreement are
secured by substantially all our assets and certain of our subsidiaries' assets.
As of December 31, 2000, we had issued a notice to draw the remaining available
balance under our credit facility, which amount was fully funded in January
2001.

     The credit agreement contains certain financial and other covenants that
restrict, among other things, our ability to incur or create additional debt,
enter into mergers or consolidations, dispose of a significant amount of assets,
pay cash dividends, or change the nature of our business. We will also be
subject to certain negative covenants, including covenants regarding the
achievement of certain performance targets and the maintenance of certain
financial ratios. In addition, the amounts outstanding under the credit facility
are subject to mandatory prepayments in certain circumstances.

     We executed an amendment and consent to the credit agreement subsequent to
December 31, 2000. Pursuant to the amendment, the interest rates applicable to
borrowings under the facility were increased. The amendment also increased the
maximum aggregate principal amount under the optional term loan tranche of the
facilities from $400 million to $600 million, of which $350 million can be
utilized as vendor loans. The optional term loan tranche is not a binding
commitment of the lenders, rather it provides a vehicle for any of the lenders
to loan us additional funds under the credit facility.

     The amendment also changed several of the covenants applicable to us. Any
default under the consolidated fixed charge coverage ratio for the fourth
quarter of 2000 was waived and the test was suspended for the first quarter of
2001. The amendment requires us to maintain substantially all of our cash and
cash equivalents in a collateral and securities account with a lender bank and
the remainder of our funds in a separate operating account. The amendment also
contains a waiver that permitted the explanatory paragraph included in our
auditor's opinion for the year ended December 31, 2000.

     As part of the amendment, we are required to deliver definitive
documentation with respect to vendor financing (in an aggregate amount of at
least $250 million) and convertible notes (in an aggregate amount of at least
$100 million), no later than April 30, 2001. We are attempting to secure vendor
financing in the amount of $250 million. If we do not meet the April 30, 2001
deadline described above, we will be in default under our credit facility unless
we receive a waiver. There can be no assurance that we will execute either the
vendor financing or convertible notes by such date or at all. As a result, the
Company has restated its December 31, 2000 consolidated balance sheet to
classify the outstanding debt to a current liability. In addition, the Company
has a new financial covenant that requires compliance effective June 30, 2001
for which there can be no assurance.

   Stock Purchase Agreement



                                       9
   10

     On December 7, 2000, we entered into a stock purchase agreement with RGC
International Investors, LDC, or RGC, as a private placement pursuant to Section
4(2) of the Securities Act of 1933. Pursuant to the purchase agreement, we may,
subject to satisfying certain conditions, at our sole discretion during the 18
months from effectiveness of the resale registration statement, require RGC to
purchase up to $250 million of our Class A common stock in a series of draw
downs. Additionally, we issued 4,972,370 warrants to RGC to purchase an equal
number of shares of our Class A common stock at an exercise price of $3.62 per
share. Warrants to purchase 3,729,278 shares vested on December 7, 2000. The
remaining 1,243,092 warrants will vest pro rata with each tranche purchased
after we have drawn down a total of $150 million.

   A draw down is initiated upon our delivery of a draw down notice that will
include a draw down amount and a minimum price at which we are willing to issue
stock to RGC. The number of shares to be purchased by RGC for each tranche will
be based upon the volume-weighted average trading price, or VWAP, of the shares
for each of the nine business days following the receipt of a draw down notice.
If, on any given date, the maximum permitted draw down amount is less than $1
million, or if the VWAP is at or below $2 per share for the preceding trading
day, we may not deliver a draw down notice. If the VWAP is at or below $2 per
share on any day during a draw down period, the total amount of the draw down
will be reduced by the percentage of the draw down amount attributable to that
particular day.

   RGC may sell the shares of Class A common stock purchased under the purchase
agreement, including upon exercise of the warrants, from time to time on the
principal exchange or market upon which our common stock is then listed or in
negotiated transactions at prices determined at the time of sale. However,
pursuant to the terms of the purchase agreement and warrants, we may not give
notice of a draw down and RGC may not exercise warrants if doing so would result
in RGC's ownership of greater than 9.9% of our Class A common stock. Further, we
may not issue 20% or more of our common stock as of December 7, 2000, or 20% or
more of our voting power outstanding as of December 7, 2000, without shareholder
approval.

   The purchase agreement is contingent upon certain conditions, including a
minimum trading price of $2.00 per share for our common stock at the time of
draw down, limits on the amount that can be drawn down based on trading price
and trading volume of our common stock, and the listing of our common stock on a
principal trading exchange or market such as the Nasdaq National Market or the
Nasdaq SmallCap Market. We may not be able to obtain all or any part of the $250
million equity financing unless the price and volume of our common stock
increase significantly and we may not be able to obtain any other additional
financing on terms acceptable to us.

   Convertible Notes

     We are currently in negotiations for the issuance of convertible notes.
Although we have not entered into a definitive agreement, and can provide no
assurance that we will reach such an agreement, we expect that any such notes
will be conditioned on completion of the vendor financing discussed above.
Definitive documentation for the issuance of up to $100 million of convertible
notes must be completed as of April 30, 2001, as a condition to our credit
facility, as amended. Under the amended credit facility, we are required to
deliver definitive documentation with respect to convertible notes (in an
aggregate amount of at least $100 million), no later than April 30, 2001. There
can be no assurance that the Company can successfully negotiate the issuance of
convertible notes as required by the amended credit facility. As a result, the
Company has restated its December 31, 2000 consolidated balance sheet to
classify the outstanding debt to a current liability. If we do not enter into a
definitive agreement by that date, we will be in default under the credit
facility unless we receive a waiver.

   Historical Cash Flows and Working Capital

     For the year ended December 31, 2000 we used cash in operations of $669.1
million, due primarily to the operating loss for the period, partially offset by
depreciation and amortization, loss recognized on the write-down of
available-for-sale securities, stock based and other non-cash compensation,
asset impairment charges recorded during the year and other charges. We used
cash in operations of $313.4 million for the year ended December 31, 1999, due
primarily to the operating loss for the period reduced by depreciation and
amortization, non-cash stock-based compensation and an increase in current
liabilities.



                                       10
   11

     We used $296.4 million of cash in investing activities in 2000 relating to
the purchase of property and equipment, advances to international ventures and
cash paid for acquisitions, partially offset by the use of restricted cash for
interest payments and net maturities of short-term investments. In 1999, we used
cash in investing activities of $354.8 million, consisting primarily of the
purchase of property and equipment and net purchases of short-term investments,
partially offset by the use of restricted cash for interest payments.

     Cash flows provided by financing activities amounted to $785.8 million in
2000, consisting primarily of the draw-down of our credit facility and net
proceeds from the issuance of common stock. For 1999, cash flows provided by
financing activities amounted to $692.2 million, consisting primarily of net
proceeds from the issuance of preferred stock and a $200 million draw-down of
our credit facility.

     At December 31, 2000, we had working capital of $249.8 million including
unrestricted cash (including cash equivalents and short-term investments) of
$357.2 million, compared to working capital of $342.7 million and cash of $556.9
million at December 31, 1999. The decrease in working capital is primarily a
result of the use of cash and cash equivalents to cover our operating
expenditures and purchase property and equipment. We will need a significant
amount of cash to continue to build our networks, market our services and cover
operating expenditures.

     Our total assets increased to $1,209.5 million at December 31, 2000, from
$1,131.8 million as of December 31, 1999, due primarily to the purchase of
property and equipment, acquired companies and investments in and advances to
international ventures, partially offset by a decrease in current assets.


ITEM 7A.   QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

     We have certain exposure to financial market risks, including changes in
interest rates and other relevant market prices. Specifically, an increase or
decrease in interest rates would affect interest costs relating to our credit
facility. At December 31, 2000, we had an outstanding loan balance of $789.7
million under the credit facility. $575.0 million incurs interest at a floating
rate tied to a LIBOR or an alternate base rate and the remaining $214.7 million
incurs interest at a fixed rate of 11.125% per annum. If the interest rate
increased by 1%, then interest expense would increase by approximately $5.8
million. The outstanding balance under the credit facility that incurs interest
at a floating rate represents approximately 40% of our outstanding long-term
debt.

     Changes in interest rates do not have a direct impact on interest expense
relating to our remaining fixed rate long-term debt, although the fair market
value of our fixed rate debt is sensitive to changes in interest rates. If
market rates declined, our interest payments could exceed those based on the
current market rate. We currently do not use interest rate derivative
instruments to manage our exposure to interest rate changes, but may do so in
the future.

     We also maintain securities with an original maturity of greater than 90
days, but less than one year. These securities are classified as "available for
sale." An immediate increase or decrease in interest rates could have a material
impact on the fair value of these financial instruments or on our short-term
investment portfolio. Based on the fact that the investments are short-term and
are in government securities and/or high-grade corporate debt, no material
interest rate exposure exists as of December 31, 2000.

                         Report of Independent Auditors



The Board of Directors and Stockholders
Teligent, Inc.

We have audited the accompanying consolidated balance sheets of Teligent, Inc.
as of December 31, 2000 and 1999, and the related consolidated statements of
operations, shareholders' (deficit) equity, and cash flows for each of the three
years in the period ended December 31, 2000. Our audits also included the
financial statement schedule listed in the Index at Item 14(a). These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements are free
of material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of Teligent, Inc. at
December 31, 2000 and 1999, and the consolidated results of their operations and
their cash flows for each of the three years in the period ended December 31,
2000, in conformity with accounting principles generally accepted in the United
States. Also, in our opinion, the related financial statement schedule, when
considered in relation to the basic financial statements taken as a whole,
presents fairly in all material respects the information set forth therein.

The accompanying financial statements have been prepared assuming that Teligent,
Inc. will continue as a going concern. As more fully described in Note 1, the
Company has incurred recurring operating losses and has a substantial need for
working capital. These conditions raise substantial doubt about the Company's
ability to continue as a going concern. Management's plans in regard to these
matters are also described in Note 1. The financial statements do not include
any adjustments to reflect the possible future effects on the recoverability and
classification of assets or the amounts and classification of liabilities that
may result from the outcome of this uncertainty.

As described in Note 8, the December 31, 2000 consolidated balance sheet has
been restated to reflect the classification of the Company's outstanding debt
from a long-term liability to a current liability.

                                 TELIGENT, INC.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.     NATURE OF BUSINESS AND LIQUIDITY

       Teligent, Inc. ("Teligent" or the "Company") is a full-service
communications company that offers business customers local and long-distance
telephony; high-speed data and Internet access services over the Company's
digital SmartWave(TM) local networks. The Company's SmartWave(TM) local
networks integrate advanced fixed wireless technologies with traditional
broadband wireline technology.

       The Company has had operating losses and negative cash flow since its
inception. Development of the Company's telecommunications networks and other
elements of its business are costly, and these costs have resulted in negative
cash flow. The Company will require significant capital to, among other things,
finance the further development and expansion of its business and deployment of
its services, including purchasing and installing telecommunications equipment
and operating its network, among other activities. With the Company's existing
cash, cash equivalents and short-term investments, the Company does not have
sufficient funds to operate its business through 2001. These conditions raise
substantial doubt about the Company's ability to continue as a going concern.
The Company's continued existence is dependent upon receiving additional funding
to operate its business. The Company cannot guarantee that it will be able to
obtain additional funding on acceptable terms.

       In order to conserve cash reserves, the Company has targeted reductions
in selling, general and administrative expenses, network expenses and other
operating costs. In addition, the Company has implemented a focused control over
capital expenditures, which should enable it to selectively deploy assets only
in market areas with the greatest return potential.

2.     SIGNIFICANT ACCOUNTING POLICIES

  Consolidation

       The consolidated financial statements include the accounts of the Company
and its subsidiaries after elimination of all significant intercompany
transactions. International ventures are accounted for by the equity method.

  Cash and Cash Equivalents

       The Company considers all highly liquid investments purchased with
maturity dates of 90 days or less at the time of purchase to be cash
equivalents. Cash equivalents consist of money market fund investments and
short-term commercial paper. Restricted cash and other investments relates
primarily to cash and securities which had been held exclusively to fund
interest payments and to secure letters of credit obtained by the Company.

  Short-Term Investments

       The Company classifies all of its short-term investments as
available-for-sale securities and such investments are reported at fair value,
which approximates cost at December 31, 2000. The Company determines the fair
value of its short-term investments based on quoted market prices. Realized
gains or losses are included in earnings and are determined using the specific
identification method.

       At December 31, 2000, the Company's investments are primarily comprised
of corporate bonds, medium and short-term notes and Euro dollar bonds. Gains and
losses for available-for-sale securities have been recognized in interest income
for the years ended December 31, 2000 and 1999. At December 31, 2000, $91.6
million of the Company's short-term investments are due within one year. The
remaining $5.0 million is due within two years.

                                 TELIGENT, INC.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)

  Accounts Receivable

       Accounts receivable are reflected net of an allowance for doubtful
accounts of $7.8 million and $0.9 million at December 31, 2000 and 1999,
respectively.

  Property and Equipment

       Property and equipment is stated at cost. Costs incurred to prepare an
asset for service, including installation costs; labor and related supplies are
capitalized and depreciated over the useful life of the asset. Depreciation is
computed on the straight-line method over the estimated useful lives of the
assets: 3-10 years for telecommunications equipment, computer systems, and
furniture, and the lesser of the life of the asset or the lease term for
leasehold improvements. Undeployed assets are not depreciated until placed in
service. Repairs and maintenance are charged to expense when incurred.
Construction of these assets takes generally less than 90 days, therefore, no
interest costs were capitalized during the years ended December 31, 2000, 1999
or 1998.

  Intangible Assets

       Intangible assets are comprised primarily of fixed wireless licenses,
debt financing costs and acquired intangibles. Fixed wireless licenses represent
the direct costs of obtaining such licenses. Debt financing costs represent fees
and other costs incurred in connection with the Credit Facility (see Note 8),
and the issuance of long-term debt. Debt financing costs are amortized to
interest expense over the term of the related debt. Acquired intangibles
represent the excess cost of acquisitions over the fair value of assets or
shares of stock acquired. Fixed wireless licenses, debt financing costs and
acquired intangibles are amortized over useful lives of 15 years, 8-10 years and
5-15 years, respectively. During 2000, the Company recorded a write-down of
intangible assets. See Note 6. No impairment expense was recognized during the
years ended December 31, 1999 or 1998.

  Long-Lived Assets

       In accordance with Statement of Financial Accounting Standards ("SFAS")
No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to be Disposed Of", management periodically reviews, if impairment
indicators exist, the carrying value and lives of long-lived assets. During
2000, the Company recorded a write-down of certain long-lived assets that were
determined to be impaired in accordance with SFAS No. 121. See Note 3. No
impairment expense was recognized during the years ended December 31, 1999 or
1998.

  Income Taxes

       The Company uses the liability method of accounting for income taxes.
Deferred income taxes result from temporary differences between the tax basis of
assets and liabilities and the basis reported in the financial statements.

  Revenue Recognition

       Revenue from providing communications services is recognized when
services are rendered based on usage of the Company's network and from the sale
of certain telecommunications equipment.

  Advertising Costs

       Costs related to advertising are expensed when the advertising occurs.
Advertising expense was $20.3 million, $19.7 million and $16.1 million for the
years ended December 31, 2000, 1999 and 1998, respectively.

                                 TELIGENT, INC.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

  Net Loss Per Share

       The Company follows the provisions of Statement of Financial Accounting
Standards ("SFAS") No. 128, "Earnings Per Share," which requires the Company to
present basic and fully diluted earnings per share. Common stock equivalents
have been excluded from the calculation because their effect would be
anti-dilutive.

  Stock-Based Compensation

       The Company accounts for its stock-based compensation in accordance with
the provisions of Accounting Principles Board Opinion No. 25, "Accounting for
Stock Issued to Employees" ("APB No. 25"), and has provided pro forma
disclosures of net loss and net loss per share in accordance with SFAS No. 123,
"Accounting for Stock-Based Compensation" ("SFAS No. 123").

  Business Segments

       In June 1997, the Financial Accounting Standards Board issued SFAS No.
131, "Disclosures About Segments of an Enterprise and Related Information"
("SFAS No. 131"). SFAS No. 131 changes the way public companies report segment
information in annual financial statements and also requires those companies to
report selected segment information in interim financial reports to
stockholders. It also establishes standards for related disclosures about
products and services, geographic areas, and major customers. Management
believes the Company's operations comprise only one segment.

  Concentration of Credit Risk and Major Vendor

       Financial instruments that may subject the Company to concentration of
credit risk consist primarily of trade receivables. The Company's trade
receivables are geographically dispersed and include customers in many different
industries. The Company believes that its risk of loss is limited due to the
diversity of its customers and geographic sales areas.

       The Company used one vendor as a primary supplier of network equipment
for use in the construction of its digital SmartWave(TM) local networks until
September 2000. As of December 31, 2000 and 1999, amounts due to this vendor for
trade payables totaled $4.7 million and $167.8 million, respectively. Capital
expenditures from this vendor represented 12%, 40% and 47% of the Company's
total capital expenditures for the years ended December 31, 2000, 1999 and 1998,
respectively.

  Use of Estimates

       The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

  Reclassifications

       Certain amounts in the prior periods' financial statements have been
reclassified to conform to the current year's presentation.

3.     RESTRUCTURING AND ASSET IMPAIRMENT

              On November 8, 2000, the Company announced a plan to restructure
its operations in order to focus future business growth on the Company's fixed
wireless networks. This restructuring included a workforce reduction associated
with its efforts to realign its sales, operations and real estate organizations.
As a result of this work force reduction and organizational realignment, the
Company recorded a $14.5 million restructuring charge in the quarter ending
December 31, 2000. The charge consisted of personnel-related costs, primarily
related to severance totaling $6.8 million and office closure and other costs of
$7.7 million. As of December 31, 2000, the balance of the restructuring reserve
was $10.9 million.

       The Company recorded a $20.1 million asset impairment charge during the
quarter ended December 31, 2000. The charge consisted principally of the
carrying value of assets abandoned in nine markets where the Company has decided
to focus on a wholesale business strategy.

Senior Notes Offering

       In November 1997, the Company issued $300 million of 11 1/2% Senior Notes
due 2007 (the "Senior Notes"). The Company used $93.9 million of the net
proceeds of this offering to purchase a portfolio of Treasury securities which
were classified as restricted cash and investments on the balance sheet, and
were pledged as collateral for the payment of interest on the Senior Notes
through December 1, 2000. Interest on the Senior Notes accrues at a rate of
11 1/2% per annum and is payable semi-annually in June and December.

       On or after December 1, 2002, the Notes will be redeemable at the option
of the Company, in whole at any time or in part from time to time, at prices
ranging from 100.00% to 105.75% (expressed in percentages of the principal
amount thereof).

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

       Upon the occurrence of a change in control, as defined in the Senior
Notes agreement, each holder of the Senior Notes will have the right to require
the Company to repurchase all or any part of such holder's Senior Notes at a
purchase price in cash equal to 101% of the principal amount.

  Senior Discount Notes Offering

       On February 20, 1998, the Company completed an offering (the "Discount
Notes Offering") of $440 million 11 1/2% Senior Discount Notes due 2008 (the
"Senior Discount Notes"). The Company received $243.1 million in net proceeds
from the Discount Notes Offering, after deductions for offering expenses of $7.6
million. Under a 1998 exchange offer, all outstanding Senior Discount Notes were
exchanged for 11 1/2% Series B Discount Notes due 2008 (the "New Discount
Notes") which have been registered under the Securities Act of 1933, as
amended. The New Discount Notes are identical in all material respects to the
Senior Discount Notes.

       On or after March 1, 2003, the New Discount Notes will be redeemable at
the option of the Company on terms similar to those of the Senior Notes. In
addition, the New Discount Notes contain change in control repurchase
commitments similar to the Senior Notes.

  Credit Facility

       On July 2, 1998, the Company entered into a credit agreement, as
subsequently amended, (the "Bank Credit Agreement") with certain lenders,
providing for credit facilities up to an aggregate of $800 million (the "Credit
Facility"). Availability of funds under the Credit Facility were subject to
certain conditions as defined in the Bank Credit Agreement, all of which were
met prior to the draw down of the entire facility in January 2001. Substantially
all of the Company's assets secure the obligations under the Bank Credit
Agreement.

       The Credit Facility is structured into three separate tranches consisting
of a term loan facility, a delayed draw term loan facility and a revolving
credit facility, each of which has a final maturity of eight years. Interest
accrues on $575.0 million of outstanding borrowings based on a floating rate
tied to the prevailing LIBOR rate and adjusts based on the attainment of certain
key revenue and leverage benchmarks. The remaining $214.7 million accrued
interest at a fixed rate of 11.125% per annum. The Company incurred commitment
and other fees in connection with obtaining the Credit Facility totaling $19.9
million, which is being amortized over eight years. The Credit Facility contains
certain financial and other covenants that restrict, among other things, the
Company's ability to (a) incur or create additional debt, (b) enter into mergers
or consolidations, (c) dispose of a significant amount of assets, (d) pay cash
dividends, or (e) change the nature of its business. The amounts outstanding
under the Credit Facility are subject to mandatory prepayments in certain
circumstances.

       The Company executed an Amendment and Consent (the "Amendment") to the
Bank Credit Agreement subsequent to December 31, 2000. Pursuant to the
Amendment, the interest rates applicable to borrowings under the Credit Facility
were increased. The Amendment also increased the maximum aggregate principal
amount under the optional term loan tranche of the Credit Facility from $400
million to $600 million, of which $350 million can be utilized as vendor loans.
The optional term loan tranche is not a binding commitment of the lenders,
rather it provides a vehicle for any of the lenders to loan the Company
additional funds under the Credit Facility.

       The Amendment also changed several of the covenants applicable to the
Company. The Company received a waiver for default of the fixed charge coverage
ratio for the period ending December 31, 2000 from the lenders as part of the
Amendment, and the test was suspended for the first quarter of 2001. The Company
was in compliance with all other debt covenants of the Credit Facility as of
December 31, 2000. The Amendment also requires the Company to maintain
substantially all of its cash and cash equivalents in a collateral and
securities account with a lender bank and the remainder of its funds in a
separate operating account. The Amendment also contains a waiver that permitted
the explanatory paragraph included in the Company's auditor's opinion for the
year ended December 31, 2000.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)


       As part of the Amendment, the Company is required to deliver definitive
documentation with respect to vendor financing (in an aggregate amount of at
least $250 million) and convertible notes (in an aggregate amount of at least
$100 million), no later than April 30, 2001. The Company is attempting to secure
vendor financing in the amount of $250 million. If the Company does not meet the
April 30, 2001 deadline described above, it will be in default under its Credit
Facility. There can be no assurance that the Company will execute either the
vendor financing or convertible notes by such date or at all. In addition, the
Company has a new financial covenant that requires compliance effective June 30,
2001 for which there can be no assurance.

       There can be no assurance that the Company can obtain vendor financing or
convertible notes as required by the amended credit facility. Accordingly, the
Company has restated its December 31, 2000 consolidated balance sheet to
classify its outstanding debt as a current liability.

       During the years ended December 31, 2000 and 1999, the Company did not
record an income tax benefit or expenses. The ultimate realization of deferred
tax assets is dependent upon the generation of future taxable income during the
periods in which those temporary differences become deductible. At December 31,
2000, the Company had federal net operating loss carryforwards of $1.534 billion
that expire in various amounts through 2020.

       A reconciliation between income taxes computed using the statutory
federal income tax rate and the effective rate, for the years ended December 31,
2000 and 1999, is as follows:

       In July 2000, the Company closed an investment in ICG Communications
("ICG"); whereby a subsidiary of the Company acquired 2,996,076 shares of ICG
common stock in exchange for one million shares of Class A Common Stock (the
"ICG Transaction"). The value of the Company's investment in ICG as of the
closing date was $62.0 million. Subsequent to the closing date of the ICG
Transaction, the market value of ICG common stock decreased significantly, and
the Company has concluded that the decline is permanent. Accordingly, the
Company has written its investment in ICG common stock down to its market value,
which management believes approximately fair value. At December 31, 2000, the
market value of the investment in ICG common stock was $400,000 and Teligent had
realized a loss on this investment of $61.6 million, which is included in other
expenses.

       In September 2000, the Company resolved an outstanding liability with one
of its vendors. This transaction resulted in a reduction of telecommunications
costs (cost of services) of $39.7 million for the year ended December 31, 2000.
Additionally, the transaction resulted in the payment of $17.3 million in
interest to the vendor.

13.    CONVERTIBLE REDEEMABLE PREFERRED STOCK

       On December 3, 1999, the Company completed the sale of 500,000 shares of
its 7 3/4% Series A cumulative convertible redeemable preferred stock,
liquidation preference $1,000 per share, par value $.01 per share to an investor
group for gross proceeds of $500 million. At December 31, 2000 and 1999, there
were 539,543 and 500,000 shares authorized, issued and outstanding of Series A
Preferred Stock, respectively.

     The Company has authorized 10,000,000 shares of preferred stock, par value
$.01 per share. For shares issued and outstanding, see Note 13.

     On May 25, 2000, the Company's shareholders approved an amendment to the
Company's certificate of incorporation, increasing the total number of
authorized shares of Class A Common Stock to 500,000,000, eliminating the Series
B-1 common stock and increasing the number of authorized shares of Series B-2
common stock to 50,000,000 and Series B-3 common stock to 20,000,000. The
Company filed an amendment to the certificate of incorporation with the
Secretary of State of the State of Delaware as approved by the Company's
shareholders, reflecting the amendments.

   Common Stock Offering

     In April 2000, the Company completed an underwritten offering of 4,000,000
shares of Class A Common Stock at a price of $50 per share, from which the
Company raised approximately $188.3 million of net proceeds, after deducting
approximately $11.7 million of offering expenses. In addition, one of the
Company's stockholders sold 1,000,000 shares of Class A Common Stock, at a price
of $50 per share, of which the Company received no proceeds.

     Stock Purchase Agreement and Issuance of Warrants

     On December 7, 2000, the Company entered into a stock purchase agreement
with RGC International Investors, LDC ("RGC"), as a private placement pursuant
to Section 4(2) of the Securities Act of 1933. Pursuant to the purchase
agreement, the Company may, subject to satisfying certain conditions, at its
sole discretion during the 18 months from the effectiveness of the resale
registration statement, require RGC to purchase up to $250 million of its Class
A Common Stock in a series of draw-downs. Pursuant to the purchase agreement,
the Company also issued 4,972,370 warrants to RGC to purchase an equal number of
shares of Class A Common Stock at an exercise price of $3.62 per share. Warrants
to purchase 3,729,278 shares vested on December 7, 2000. The remaining 1,243,092
warrants will vest pro rata with each tranche purchased after we have drawn down
a total of $150 million.

      A draw down is initiated upon the Company's delivery of a draw down notice
that will include a draw down amount and a minimum price at which the Company is
willing to issue stock to RGC. The number of shares to be purchased by RGC for
each tranche will be based upon the volume-weighted average trading price
("VWAP") of the shares for each of the nine business days following the receipt
of a draw down notice. If, on any given date, the maximum permitted draw down
amount is less than $1 million, or if the VWAP is at or below $2 per share for
the preceding trading day, the Company may not deliver a draw down notice. If
the VWAP is at or below $2 per share during any day during a draw down period,
the total amount of the draw down will be reduced by the percentage of the draw
down amount attributable to that particular day.

     RGC may sell the shares of Class A Common Stock purchased pursuant to the
purchase agreement, including upon exercise of the warrants, from time to time
on the principal exchange or market upon which the Company's common stock is
then listed or in negotiated transactions at prices determined at the time of
sale. However, pursuant to the terms of the purchase agreement and warrants, the
Company may not give notice of a draw down and RGC may not exercise warrants if
doing so would result in RGC's ownership of greater than 9.9% of our Class A
Common Stock. Further, the Company may not issue 20% or more of our common stock
as of December 7, 2000, or 20% or more of our voting power outstanding as of
December 7, 2000, without shareholder approval.

     The purchase agreement is contingent upon certain conditions, including a
minimum trading price of $2.00 per share for the Company's common stock at the
time of draw down, limits on the amount that can be drawn down based on trading
price and trading volume of our common stock, and the listing of our common
stock on a principal trading exchange or market such as the Nasdaq National
Market or the Nasdaq SmallCap Market. We may not be able to obtain all or any
part of the $250 million equity financing unless the price and volume of our
common stock increase significantly and we may not be able to obtain any other
additional financing on terms acceptable to us.

   Company Appreciation Rights, Appreciation Units and Stock Options

     In 1996, certain employees were granted Company Appreciation Rights
("CARs") and appreciation units. At the time of the Company's Initial Public
Offering, these CARs and appreciation units were converted into options to
purchase Class A Common Stock. The Company will recognize up to $173.3 million
of compensation expense over the vesting period of the options. Through December
31, 2000, $160.2 million of stock-based compensation expense has been
recognized, and up to $13.1 million will be recognized through September 1, 2002
as follows: $12.7 million in 2001 and $400,000 in 2002. The employees receiving
these benefits are primarily executives and key employees whose compensation
expenses are typically included in general and administrative expenses for the
years ended December 31, 2000, 1999 and 1998.

     1997 Stock Incentive Plan

     The Company maintains the Teligent, Inc. 1997 Stock Incentive Plan, as
amended (the "1997 Plan"). The 1997 Plan authorizes options to purchase an
aggregate of 18,729,125 shares of Class A Common Stock, including the options
converted from the CARs and Appreciation Units. The exercise price of options
granted, as determined by the Company's Compensation Committee, approximates
fair value. Generally, all options granted under the 1997 Plan vest over a
period of five years and expire ten years from the date of grant.

     The Company applies the provisions of APB No. 25 in accounting for its
stock-based compensation. If compensation expense had been determined in
accordance with SFAS No. 123, the Company's net loss for the years ended
December 31, 2000, 1999 and 1998 would have been $892.4 million, $570.6 million
and $324.4 million, or $14.90, $10.68 and $6.16 per share, respectively. Options
arising from the conversion of CARs and Appreciation Units have been valued
based on the number and exercise price of the options issued upon conversion.
The weighted average fair value of options granted was $21.17, $47.25 and $21.91
in 2000, 1999 and 1998, respectively, using the Black-Scholes option pricing
model with the following assumptions: dividend yield 0%, risk free rate interest
rate of 6.4%, 6.0% in 1999 and 5.3% in 1998, an expected life of 5 years in 2000
and 10 years in 1999 and 1998, and an expected volatility of 1.010 in 2000, .861
in 1999 and .648 in 1998.

     Option activity for 2000, 1999 and 1998 is set forth below:

16.  EMPLOYEE BENEFIT PLANS

     Employees of the Company may participate in a 401(k) retirement plan in
which eligible employees may elect to contribute, on a tax-deferred basis, up to
15% of their compensation, not to exceed annual maximums as defined in the
Internal Revenue Code. The Company matches one-half of a participant's
contribution up to 6% of the participant's compensation, vesting over 4 years.
The Company's contributions to the plan were $2.8 million, $1.7 million and $0.9
million for 2000, 1999 and 1998, respectively.

     Effective July 1, 1999, the Company adopted the Employee Stock Purchase
Plan ("ESPP"). Under the ESPP, the Company authorized the issuance of 300,000
shares of Class A Common Stock, which allowed eligible employees to purchase
such shares at 85% of the fair value of the Class A Common Stock. As of January
2001, the Company had issued all such shares available under the ESPP. No
additional shares will be distributed under the ESPP until more shares of Class
A Common Stock are authorized for distribution under the ESPP.

18.  EVENTS SUBSEQUENT TO THE AUDITORS REPORT DATE AND TO THE INITIAL FILING OF
     FORM 10-K (UNAUDITED)

   Filing for Chapter 11 under the U.S. Bankruptcy Code

     On May 21, 2001, the Company and all of its direct and indirect domestic
subsidiaries filed voluntary petitions for relief under Chapter 11 of the U.S.
Bankruptcy Code in the United States Bankruptcy Court for the Southern District
of New York. The 21 separate cases were procedurally (but not substantively)
consolidated for joint administration. Each of the Company and the subsidiaries
included in the filings will continue to operate their businesses as debtors in
possession during the reorganization proceeding. The Company's foreign
subsidiaries were not part of the Chapter 11 filing.

     In conjunction with the filing of the petitions, the Company entered into
an interim arrangement with its lenders to provide funds, subject to certain
conditions, for near-term operations. The Bankruptcy Court approved the interim
arrangement with the Company's lenders on May 21, 2001. A hearing on the interim
arrangement is scheduled for June 13, 2001.

     While under the protection of Chapter 11, the Company may sell or otherwise
dispose of assets and liquidate or settle liabilities for amounts other than
those reflected in the consolidated financial statements. The financial
statements do not include any adjustments that might be necessary as a result of
the outcome of the uncertainties discussed herein, including the effects of any
plan of reorganization or liquidation.

     Based on the aforementioned bankruptcy coupled with the violation of
certain debt-covenants, the repayment of the debt obligations can be accelerated
by its lenders.

   Changes in Management and the Board of Directors

     On April 17, 2001, Gary Howard and Carl Vogel resigned their seats on the
Company's Board of Directors. David Berkman had resigned his seat on the
