                                 TELIGENT, INC.

         NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1. PETITION FOR RELIEF UNDER CHAPTER 11

        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 in order to facilitate the restructuring of the Company's long-term
debt and other obligations. 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
bankruptcy petitions were filed in order to preserve cash and to give the
Company and its domestic subsidiaries the opportunity to restructure their debt.
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 was held on June 13, 2001, where the Court approved further
interim financing from the Company's lenders and approved a streamlined process
whereby further Court approvals will be unnecessary for additional interim
funding. 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 Company is in default on all of its indebtedness.
The Company has classified all of its debt in the accompanying unaudited
condensed consolidated balance sheet at August 31, 2001 as liabilities subject
to compromise. In addition, as a result of these bankruptcy proceedings,
substantially all of the liabilities, litigation and claims against the Debtors
in existence at the petition date are stayed unless the stay is modified or
lifted or payment is otherwise authorized by the Bankruptcy Court.

        On August 24, 2001, the Company announced it would reconfigure retail
operations in twelve of its markets: Atlanta, Charlotte, Denver, Detroit,
Indianapolis, Kansas City, Minneapolis, Orlando, Portland, San Francisco, San
Antonio and Seattle. Eleven markets will remain after these offices close.

        On August 24, 2001, the Debtors filed a motion with the U. S. Bankruptcy
Court requesting authority to sell the Company's core assets to Teligent
Acquisition Corporation ("TAC"), subject to higher and better offers. The Court
will hold a hearing on October 3, 2001 to consider and approve the transaction
with TAC, or an alternative higher and better offer. Under agreement, TAC will
pay in excess of $115 million for the Company's core domestic fixed wireless
business and assets. The agreement is subject to numerous approvals, including
the U. S. Bankruptcy Court, the FCC, the Department of Justice, and state
regulatory agencies.


2. BASIS OF PRESENTATION

        The accompanying unaudited condensed consolidated financial statements
include the results of Teligent, Inc. and all of its direct and indirect
domestic subsidiaries for the month ended August 31, 2001. The Company's foreign
subsidiaries are not part of the Chapter 11 filing and therefore are not
included in these statements. These financial statements have been prepared on a
going concern basis,

   7

which contemplates continuity of operations, realization of assets and
liquidation of liabilities in the ordinary course of business. These statements
include intercompany balances that would be eliminated, in accordance with
generally accepted accounting principles, when the results of the Company are
consolidated with all of its foreign subsidiaries.

3. SIGNIFICANT ACCOUNTING POLICIES

    The unaudited condensed consolidated financial statements have been prepared
using the accounting policies disclosed in the related annual audited financial
statements.

4. DEBT

    Total debt consists of the following (in thousands):


                                                                  
    11.5% Senior Notes due 2007..................................... $  300,000
    11.5% Senior Discount Notes due 2008............................    361,802
    Credit Facility.................................................    800,000
    Other...........................................................         80
                                                                     ----------
    Total debt                                                       $1,461,882


        The Company is in default on all of its indebtedness as a result of its
failure to deliver definitive documentation with respect to financing within the
time period required by the Amendment to the Credit Facility (described in
detail below), and because of the bankruptcy filing. As a result of the
bankruptcy filing, all of its outstanding debt has been classified as
liabilities subject to compromise.

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 pledged as collateral for the payment of interest on the Senior Notes
through December 1, 2000.

    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).

    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 2000 (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.

   8

    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
was being amortized over eight years. As a result of the bankruptcy filing,
unamortized commitment fees including those incurred in connection with
obtaining the Credit Facility were written off as reorganization charges in July
2001 in the amount of $27.6 million. 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 eliminated 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.

    As part of the Amendment, the Company was 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, which requirement was

   9

subsequently waived to May 21, 2001. The Company was not successful in securing
the additional financing and on May 21, 2001 the Company filed voluntary
petitions for relief under Chapter 11 of the U.S. Bankruptcy Code.

5. 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.

    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.

6. RESTRUCTURING RESERVE

    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 of 600
employees associated with efforts to realign the 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 $6.8
million for severance and other compensation, $5.8 for net costs relating to
lease terminations, and other costs of $1.9 million. On February 15, 2001, the
Company announced an additional workforce reduction, terminating 172 employees
company-wide and recording an additional $600,000 to the restructuring reserve.
On August 24, 2001, the Company announced it would discontinue retail operations
in twelve of its markets. This restructuring included a workforce reduction of
147 employees. At August 31, no additional restructuring costs were recorded as
a result of the August work-force reduction. As of August 31, 2001, the reserve
balance totaled $6.4 million, consisting of personnel-related costs, primarily
related to severance totaling $0.9 million, office closures totaling $4.0
million and other costs of $1.5 million.

7. REORGANIZATION CHARGES

    Reorganization costs totaling approximately $64.3 million have been booked
as of August 31, 2001, consisting of professional fees of $10.2 million related
to the bankruptcy filings, $27.6 million related to the write off of deferred
debt financing costs, $6.2 million for loss on the write-off of goodwill due to
office closings and $20.3 for the loss on the sale of subsidiaries.

8. ASSET IMPAIRMENT

    Due to the bankruptcy filing, the Company is considering if an impairment of
assets has occurred under Statement of Financial Accounting Standards number
121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to be Disposed of" ("SFAS 121"). As the Company is currently undergoing
reorganization, there is not currently a definitive business plan in place with
which to determine if an impairment has occurred or, if an impairment has
occurred, the amount of such impairment. As a result, the Company has not
reduced the carrying values of its assets in the accompanying unaudited
condensed, consolidated financial statements. If it is determined that an
impairment has occurred, the Company believes that it will have a material
effect on that period's condensed consolidated financial statements.
