ITEM 3.  INCORPORATION OF DOCUMENTS BY REFERENCE.

         The following documents, previously filed with the Commission pursuant
to the Securities Exchange Act of 1934, as amended (the "Exchange Act"), are
incorporated herein by reference.

                  (a) The Company's Annual Report on Form 10-K for the fiscal
         year ended December 31, 2000, as amended by Form 10-K/A filed June 12,
         2001.

                  (b) AT&T Corp.'s Annual Report for the Liberty Media 401(k)
         Savings Plan (the "Plan") on Form 11-K for the fiscal year ended
         December 31, 2000.

                  (c) The Company's Quarterly Report on Form 10-Q for the
         quarter ended March 31, 2001, as amended by Form 10-Q/A filed June 20,
         2001.

                  (d) The Company's Current Reports on Form 8-K filed March 7
         and June 26, 2001.

                  (e) The description of the Company's Series A common stock
         contained in the Company's Registration Statement on Form S-1
         (Registration Statement Number 333-55998) (the "S-1") and any amendment
         or report filed for the purpose of updating such description.

                  (f) The consolidated financial statements and related
         financial statement schedule of Teligent, Inc., as of December 31, 2000
         and 1999 and for each of the years in the three


                                      II-1
<PAGE>   3
         year period ended December 31, 2000, which appear in the Annual Report
         on Form 10-K/A for the year ended December 31, 2000 of Teligent, Inc.,
         filed on July 5, 2001. On May 21, 2001, Teligent, Inc. 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.

         On May 7, 2001, certain subsidiaries and assets of AT&T Corp. which had
previously been attributed to AT&T's Liberty Media Group but which had not been
previously held by the Company were contributed to the Company in anticipation
of its split off from AT&T. Those subsidiaries and assets, which constitute only
a portion of our overall assets, are being accounted for in a manner similar to
a pooling of interests and, therefore, the financial statements of the Company
for periods prior to the contributions have been restated to include the
financial position and results of operations of the contributed assets from the
dates of their acquisition by AT&T. Accordingly, the following information is
incorporated by reference from the S-1: (1) the information under the captions
titled "Capitalization," "Selected Financial Information" and "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
(2) the following financial statements and notes thereto of the Company and
subsidiaries, which have been restated to give effect to the aforementioned
contribution: (x) the balance sheets of the Company as of March 31, 2001 and
December 31, 2000, and the related consolidated statements of operations and
comprehensive earnings, stockholder's equity, and cash flows for the three
months ended March 31, 2001 and 2000; and (y) the balance sheets of the Company
as of December 31, 2000 and 1999 and the related consolidated statements of
operations and comprehensive earnings, stockholder's equity, and cash flows for
the year ended December 31, 2000, and the period from March 1, 1999 to December
31, 1999 (Successor periods) and from January 1, 1999 to February 28, 1999 and
for the year ended December 31, 1998 (Predecessor periods).

         All documents subsequently filed by the Company or the Plan with the
Commission pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act
prior to the filing of a post-effective amendment to this registration statement
which indicates that all securities offered have been sold or which deregisters
all securities then remaining unsold shall be deemed to be incorporated by
reference in this registration statement and made a part hereof from their
respective dates of filing (such documents, and the documents enumerated above,
being hereinafter referred to as "Incorporated Documents"); provided, however,
that the documents enumerated above or subsequently filed by the Company
pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act in each year
during which the offering made by this registration statement is in effect prior
to the filing with the Commission of the Company's Annual Report on Form 10-K
covering such year shall not be Incorporated Documents or be incorporated by
reference in this Registration Statement or be a part hereof from and after the
filing of such Annual Report on Form 10-K.

         Any statement contained in an Incorporated Document shall be deemed to
be modified or superseded for purposes of this Registration Statement to the
extent that a statement contained herein or in any other subsequently filed
Incorporated Document modifies or supersedes such statement. Any such statement
so modified or superseded shall not be deemed, except as so modified or
superseded, to constitute a part of this Registration Statement.

         Not applicable.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL.

         Not applicable.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Section 145 of the Delaware General Corporation Law ("DGCL") provides,
generally, that a corporation shall have the power to indemnify any person who
was or is a party or is threatened to be made a party to any threatened, pending
or completed action, suit or proceeding (except actions by or in the right of
the corporation) by reason of the fact that such person is or was a director,
officer, employee or agent of the corporation against all expenses, judgments,
fines and amounts paid in settlement actually and reasonably incurred by such
person in connection with such action, suit or proceeding if such person acted
in good faith and in a manner such person reasonably believed to be in or not
opposed to the best interests of the corporation and, with respect to any
criminal action or proceeding, had no reasonable cause to believe his or her
conduct was unlawful. A corporation may similarly indemnify such person for
expenses actually and reasonably incurred by such person in connection with the
defense or settlement of any action or suit by or in the right of the
corporation, provided such person acted in good faith and in a manner he or she
reasonably believed to be in or not opposed to the best interests of the
corporation, and, in the case of claims, issues and matters as to which such
person shall have been adjudged liable to the corporation, provided that a court
shall have determined, upon application, that, despite the adjudication of
liability but in view of all of the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such expenses which such court
shall deem proper.

         Section 102(b)(7) of the DGCL provides, generally, that the certificate
of incorporation may contain a provision eliminating or limiting the personal
liability of a director to the corporation or its stockholders for monetary
damages for breach of fiduciary duty as a director, provided that such provision
may not eliminate or limit the liability of a director (i) for any breach of the
director's duty of loyalty to the corporation or its stockholders, (ii) for acts
or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) under Section 174 of Title 8 of the DGCL, or
(iv) for any transaction from which the director derived an improper personal
benefit. No such provision may eliminate or limit the liability of a director
for any act or omission occurring prior to the date when such provision became
effective.

         Article V, Section E of the Restated Certificate of Incorporation, as
amended ("Liberty charter"), of Liberty, provides as follows:

         1. Limitation On Liability. To the fullest extent permitted by the DGCL
as the same exists or may hereafter be amended, a director of Liberty shall not
be liable to Liberty or any of its stockholders for monetary damages for breach
of fiduciary duty as a director. Any repeal or


                                      II-3
<PAGE>   5
modification of this paragraph 1 shall be prospective only and shall not
adversely affect any limitation, right or protection of a director of Liberty
existing at the time of such repeal or modification.

         2.       Indemnification.

                  (a) Right to Indemnification. Liberty shall indemnify and hold
         harmless, to the fullest extent permitted by applicable law as it
         presently exists or may hereafter be amended, any person who was or is
         made or is threatened to be made a party or is otherwise involved in
         any action, suit or proceeding, whether civil, criminal, administrative
         or investigative (a "proceeding") by reason of the fact that he, or a
         person for whom he is the legal representative, is or was a director or
         officer of Liberty or is or was serving at the request of Liberty as a
         director, officer, employee or agent of another corporation or of a
         partnership, joint venture, trust, enterprise or nonprofit entity,
         including service with respect to employee benefit plans, against all
         liability and loss suffered and expenses (including attorneys' fees)
         reasonably incurred by such person. Such right of indemnification shall
         inure whether or not the claim asserted is based upon matters which
         antedate the adoption of this Section E. Liberty shall be required to
         indemnify or make advances to a person in connection with a proceeding
         (or part thereof) initiated by such person only if the proceeding (or
         part thereof) was authorized by the board of directors of Liberty.

                  (b) Prepayment of Expenses. Liberty shall pay the expenses
         (including attorneys' fees) incurred by a director or officer in
         defending any proceeding in advance of its final disposition, provided,
         however, that the payment of expenses incurred by a director or officer
         in advance of the final disposition of the proceeding shall be made
         only upon receipt of an undertaking by the director or officer to repay
         all amounts advanced if it should be ultimately determined that the
         director or officer is not entitled to be indemnified under this
         paragraph or otherwise.

                  (c) Claims. If a claim for indemnification or payment of
         expenses under this paragraph is not paid in full within 60 days after
         a written claim therefor has been received by Liberty, the claimant may
         file suit to recover the unpaid amount of such claim and, if successful
         in whole or in part, shall be entitled to be paid the expense of
         prosecuting such claim. In any such action, Liberty shall have the
         burden of proving that the claimant was not entitled to the requested
         indemnification or payment of expenses under applicable law.

                  (d) Non-Exclusivity of Rights. The rights conferred on any
         person by this paragraph shall not be exclusive of any other rights
         which such person may have or hereafter acquire under any statute,
         provision of the Liberty charter, Liberty's bylaws, agreement, vote of
         stockholders or resolution of disinterested directors or otherwise.

                  (e) Other Indemnification. Liberty's obligation, if any, to
         indemnify any person who was or is serving at its request as a
         director, officer, employee or agent of another corporation,
         partnership, joint venture, trust, enterprise or nonprofit entity shall
         be reduced


                                      II-4
<PAGE>   6
         by any amount such person may collect as indemnification from such
         other corporation, partnership, joint venture, trust, enterprise or
         nonprofit entity.

         3. Amendment or Repeal. Any amendment, modification or repeal of the
foregoing provisions of this Section E shall not adversely affect any right or
protection hereunder of any person in respect of any act or omission occurring
prior to the time of such amendment, modification or repeal.

ITEM 7.  EXEMPTION FROM REGISTRATION CLAIMED.

         Not Applicable

ITEM 8.  EXHIBITS.

         See Exhibit Index on page II-8.

ITEM 9.  UNDERTAKINGS.

         (a)      The Company hereby undertakes:

                  (1) To file, during any period in which offers or sales are
being made, a post-effective amendment to this registration statement:

                        (i) To include any prospectus required by Section
         10(a)(3) of the Securities Act;

                        (ii) To reflect in the prospectus any facts or events
         arising after the effective date of the registration statement (or the
         most recent post-effective amendment thereof) which, individually or in
         the aggregate, represent a fundamental change in the information set
         forth in the registration statement;

                        (iii) To include any material information with respect
         to the plan of distribution not previously disclosed in the
         registration statement or any material change to such information in
         the registration statement;

provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by the Company pursuant to
Section 13(a) or Section 15(d) of the Exchange Act that are incorporated by
reference in the registration statement.

                  (2) That, for the purpose of determining any liability under
the Securities Act, each such post-effective amendment shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.


                                      II-5
<PAGE>   7
                  (3) To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

         (b) The Company hereby undertakes that, for the purpose of determining
any liability under the Securities Act, each filing of the issuer's annual
report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where
applicable, each filing of an employee benefit plan's annual report pursuant to
Section 15(d) of the Exchange Act) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein and the offering of such securities
at the time shall be deemed to be the initial bona fide offering hereof.

         (c) Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the Company pursuant to the foregoing provisions, or otherwise, the Company
has been advised that in the opinion of the Commission such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Company of expenses incurred or paid
by a director, officer or controlling person of the Company in the successful
defense of any action, suit or proceeding) is asserted by such director, officer
or controlling person in connection with the securities being registered, the
Company will, unless in the opinion of its counsel the matter has been settled
by controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.

               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

ITEM 3.  INCORPORATION OF DOCUMENTS BY REFERENCE.

         The following documents, previously filed with the Commission pursuant
to the Securities Exchange Act of 1934, as amended (the "Exchange Act"), are
incorporated herein by reference.

                  (a) The Company's Annual Report on Form 10-K for the fiscal
         year ended December 31, 2000, as amended by Form 10-K/A filed June 12,
         2001.

                  (b) AT&T Corp.'s Annual Report for the Liberty Media 401(k)
         Savings Plan (the "Plan") on Form 11-K for the fiscal year ended
         December 31, 2000.

                  (c) The Company's Quarterly Report on Form 10-Q for the
         quarter ended March 31, 2001, as amended by Form 10-Q/A filed June 20,
         2001.

                  (d) The Company's Current Reports on Form 8-K filed March 7
         and June 26, 2001.

                  (e) The description of the Company's Series A common stock
         contained in the Company's Registration Statement on Form S-1
         (Registration Statement Number 333-55998) (the "S-1") and any amendment
         or report filed for the purpose of updating such description.

                  (f) The consolidated financial statements and related
         financial statement schedule of Teligent, Inc., as of December 31, 2000
         and 1999 and for each of the years in the three

                                      II-1

         year period ended December 31, 2000, which appear in the Annual Report
         on Form 10-K/A for the year ended December 31, 2000 of Teligent, Inc.,
         filed on July 5, 2001. On May 21, 2001, Teligent, Inc. 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.

         On May 7, 2001, certain subsidiaries and assets of AT&T Corp. which had
previously been attributed to AT&T's Liberty Media Group but which had not been
previously held by the Company were contributed to the Company in anticipation
of its split off from AT&T. Those subsidiaries and assets, which constitute only
a portion of our overall assets, are being accounted for in a manner similar to
a pooling of interests and, therefore, the financial statements of the Company
for periods prior to the contributions have been restated to include the
financial position and results of operations of the contributed assets from the
dates of their acquisition by AT&T. Accordingly, the following information is
incorporated by reference from the S-1: (1) the information under the captions
titled "Capitalization," "Selected Financial Information" and "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
(2) the following financial statements and notes thereto of the Company and
subsidiaries, which have been restated to give effect to the aforementioned
contribution: (x) the balance sheets of the Company as of March 31, 2001 and
December 31, 2000, and the related consolidated statements of operations and
comprehensive earnings, stockholder's equity, and cash flows for the three
months ended March 31, 2001 and 2000; and (y) the balance sheets of the Company
as of December 31, 2000 and 1999 and the related consolidated statements of
operations and comprehensive earnings, stockholder's equity, and cash flows for
the year ended December 31, 2000, and the period from March 1, 1999 to December
31, 1999 (Successor periods) and from January 1, 1999 to February 28, 1999 and
for the year ended December 31, 1998 (Predecessor periods).

         All documents subsequently filed by the Company or the Plan with the
Commission pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act
prior to the filing of a post-effective amendment to this registration statement
which indicates that all securities offered have been sold or which deregisters
all securities then remaining unsold shall be deemed to be incorporated by
reference in this registration statement and made a part hereof from their
respective dates of filing (such documents, and the documents enumerated above,
being hereinafter referred to as "Incorporated Documents"); provided, however,
that the documents enumerated above or subsequently filed by the Company
pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act in each year
during which the offering made by this registration statement is in effect prior
to the filing with the Commission of the Company's Annual Report on Form 10-K
covering such year shall not be Incorporated Documents or be incorporated by
reference in this Registration Statement or be a part hereof from and after the
filing of such Annual Report on Form 10-K.

         Any statement contained in an Incorporated Document shall be deemed to
be modified or superseded for purposes of this Registration Statement to the
extent that a statement contained herein or in any other subsequently filed
Incorporated Document modifies or supersedes such statement. Any such statement
so modified or superseded shall not be deemed, except as so modified or
superseded, to constitute a part of this Registration Statement.

ITEM 4.  DESCRIPTION OF SECURITIES.

         Not applicable.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL.

         Not applicable.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Section 145 of the Delaware General Corporation Law ("DGCL") provides,
generally, that a corporation shall have the power to indemnify any person who
was or is a party or is threatened to be made a party to any threatened, pending
or completed action, suit or proceeding (except actions by or in the right of
the corporation) by reason of the fact that such person is or was a director,
officer, employee or agent of the corporation against all expenses, judgments,
fines and amounts paid in settlement actually and reasonably incurred by such
person in connection with such action, suit or proceeding if such person acted
in good faith and in a manner such person reasonably believed to be in or not
opposed to the best interests of the corporation and, with respect to any
criminal action or proceeding, had no reasonable cause to believe his or her
conduct was unlawful. A corporation may similarly indemnify such person for
expenses actually and reasonably incurred by such person in connection with the
defense or settlement of any action or suit by or in the right of the
corporation, provided such person acted in good faith and in a manner he or she
reasonably believed to be in or not opposed to the best interests of the
corporation, and, in the case of claims, issues and matters as to which such
person shall have been adjudged liable to the corporation, provided that a court
shall have determined, upon application, that, despite the adjudication of
liability but in view of all of the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such expenses which such court
shall deem proper.

         Section 102(b)(7) of the DGCL provides, generally, that the certificate
of incorporation may contain a provision eliminating or limiting the personal
liability of a director to the corporation or its stockholders for monetary
damages for breach of fiduciary duty as a director, provided that such provision
may not eliminate or limit the liability of a director (i) for any breach of the
director's duty of loyalty to the corporation or its stockholders, (ii) for acts
or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) under Section 174 of Title 8 of the DGCL, or
(iv) for any transaction from which the director derived an improper personal
benefit. No such provision may eliminate or limit the liability of a director
for any act or omission occurring prior to the date when such provision became
effective.

         Article V, Section E of the Restated Certificate of Incorporation, as
amended ("Liberty charter"), of Liberty, provides as follows:

         1. Limitation On Liability. To the fullest extent permitted by the DGCL
as the same exists or may hereafter be amended, a director of Liberty shall not
be liable to Liberty or any of its stockholders for monetary damages for breach
of fiduciary duty as a director. Any repeal or

                                      II-3
5
modification of this paragraph 1 shall be prospective only and shall not
adversely affect any limitation, right or protection of a director of Liberty
existing at the time of such repeal or modification.

         2.       Indemnification.

                  (a) Right to Indemnification. Liberty shall indemnify and hold
         harmless, to the fullest extent permitted by applicable law as it
         presently exists or may hereafter be amended, any person who was or is
         made or is threatened to be made a party or is otherwise involved in
         any action, suit or proceeding, whether civil, criminal, administrative
         or investigative (a "proceeding") by reason of the fact that he, or a
         person for whom he is the legal representative, is or was a director or
         officer of Liberty or is or was serving at the request of Liberty as a
         director, officer, employee or agent of another corporation or of a
         partnership, joint venture, trust, enterprise or nonprofit entity,
         including service with respect to employee benefit plans, against all
         liability and loss suffered and expenses (including attorneys' fees)
         reasonably incurred by such person. Such right of indemnification shall
         inure whether or not the claim asserted is based upon matters which
         antedate the adoption of this Section E. Liberty shall be required to
         indemnify or make advances to a person in connection with a proceeding
         (or part thereof) initiated by such person only if the proceeding (or
         part thereof) was authorized by the board of directors of Liberty.

                  (b) Prepayment of Expenses. Liberty shall pay the expenses
         (including attorneys' fees) incurred by a director or officer in
         defending any proceeding in advance of its final disposition, provided,
         however, that the payment of expenses incurred by a director or officer
         in advance of the final disposition of the proceeding shall be made
         only upon receipt of an undertaking by the director or officer to repay
         all amounts advanced if it should be ultimately determined that the
         director or officer is not entitled to be indemnified under this
         paragraph or otherwise.

                  (c) Claims. If a claim for indemnification or payment of
         expenses under this paragraph is not paid in full within 60 days after
         a written claim therefor has been received by Liberty, the claimant may
         file suit to recover the unpaid amount of such claim and, if successful
         in whole or in part, shall be entitled to be paid the expense of
         prosecuting such claim. In any such action, Liberty shall have the
         burden of proving that the claimant was not entitled to the requested
         indemnification or payment of expenses under applicable law.

                  (d) Non-Exclusivity of Rights. The rights conferred on any
         person by this paragraph shall not be exclusive of any other rights
         which such person may have or hereafter acquire under any statute,
         provision of the Liberty charter, Liberty's bylaws, agreement, vote of
         stockholders or resolution of disinterested directors or otherwise.

                  (e) Other Indemnification. Liberty's obligation, if any, to
         indemnify any person who was or is serving at its request as a
         director, officer, employee or agent of another corporation,
         partnership, joint venture, trust, enterprise or nonprofit entity shall
         be reduced

                                      II-4
6
         by any amount such person may collect as indemnification from such
         other corporation, partnership, joint venture, trust, enterprise or
         nonprofit entity.

         3. Amendment or Repeal. Any amendment, modification or repeal of the
foregoing provisions of this Section E shall not adversely affect any right or
protection hereunder of any person in respect of any act or omission occurring
prior to the time of such amendment, modification or repeal.

                        (i) To include any prospectus required by Section

information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by the Company pursuant to
Section 13(a) or Section 15(d) of the Exchange Act that are incorporated by
reference in the registration statement.

                  (2) That, for the purpose of determining any liability under
the Securities Act, each such post-effective amendment shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

                  (3) To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

         (b) The Company hereby undertakes that, for the purpose of determining
any liability under the Securities Act, each filing of the issuer's annual
report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where
applicable, each filing of an employee benefit plan's annual report pursuant to
Section 15(d) of the Exchange Act) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein and the offering of such securities
at the time shall be deemed to be the initial bona fide offering hereof.

         (c) Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the Company pursuant to the foregoing provisions, or otherwise, the Company
has been advised that in the opinion of the Commission such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Company of expenses incurred or paid
by a director, officer or controlling person of the Company in the successful
defense of any action, suit or proceeding) is asserted by such director, officer
or controlling person in connection with the securities being registered, the
Company will, unless in the opinion of its counsel the matter has been settled
by controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.
