                                    PART II
               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

                             INTRODUCTORY STATEMENT

         This Registration Statement on Form S-8 (the "Registration Statement")
of USA Networks, Inc., a Delaware corporation (the "Company" or the
"Registrant"), relates to up to 20,000,000 shares of the Registrant's common
stock, par value $.01 per share (the "Common Stock"), issuable in connection
with the USA Networks, Inc. 2000 Stock and Annual Incentive Plan (the "Plan").


                ITEM 3. INCORPORATION OF DOCUMENTS BY REFERENCE.

         The documents listed below are incorporated by reference in this
Registration Statement. All documents filed by the Company pursuant to Sections
13(a), 13(c), 14 and 15(d) of the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), subsequent to the date of the filing of this Registration
Statement and prior to the filing of a post-effective amendment that indicates
that all securities registered hereunder have been sold, or that deregisters
all securities then remaining unsold, shall be deemed to be incorporated by
reference in this Registration Statement and to be a part hereof from the date
of the filing of such documents.

               (a)  The Company's Annual Report on Form 10-K for the fiscal
year ended December 31, 1999;

               (b)  The description of the Common Stock is contained in the
Company's Proxy Statement on Schedule 14A, dated November 20, 1996.


               ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         The Registrant's Restated Certificate of Incorporation limits, to the
maximum extent permitted by Delaware law, the personal liability of directors
for monetary damages for breach of their fiduciary duties as directors. The
Registrant's Bylaws provide that the directors, officers and certain other
persons will be indemnified to the fullest extent permitted by Delaware law
with respect to third-party actions or suits, provided such person has met the
applicable standard of conduct which permits indemnification under Delaware
law. The Registrant's Bylaws further provide that directors, officers and
certain other persons will be indemnified with respect


                                       2
<PAGE>   3

to actions or suits initiated by such person, provided that such proceeding was
authorized by the Board of Directors. The Registrant's Bylaws allow the
Registrant to pay all expenses incurred by a director, officer, employee or
agent in defending any proceeding within the scope of the indemnification
provisions as such expenses are incurred in advance of its final disposition,
subject to repayment if it is ultimately determined that such party was not
entitled to indemnity by the Registrant. From time to time, officers and
directors may be provided with indemnification agreements that are consistent
with the foregoing provisions. The Registrant believes that these agreements
are necessary to attract and retain qualified persons as directors and
officers.

         Section 145 of the Delaware General Corporation Law provides that a
corporation may indemnify a director, officer, employee or agent made a party
to an action by reason of the fact that he was a director, officer or agent of
the corporation or was serving at the request of the corporation against
expenses actually and reasonably incurred by him in connection with such action
if he acted in good faith and in a manner he reasonably believed to be in, or
not opposed to, the best interests of the corporation and, with respect to any
criminal action, had no reasonable cause to believe his conduct was unlawful.

         Insofar as indemnification for liabilities arising under the
Securities Act of 1933, as amended (the "Securities Act"), may be permitted to
directors, officers or persons controlling the Registrant pursuant to the
foregoing provisions, the Registrant has been advised that in the opinion of
the Securities and Exchange Commission, such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable.


         ITEM 8.   EXHIBITS.

         The exhibits incorporated by reference or filed as part of this
Registration Statement are listed in the Index of Exhibits that begins on page
9.


         ITEM 9.   UNDERTAKINGS.

               A.   The undersigned Registrant 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 of
1933, as amended (the "Securities Act");


                                       3
<PAGE>   4

(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;
and (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 clauses (i) and (ii) do not apply if the information required to
be included in a post-effective amendment by those clauses is contained in
periodic reports filed with or furnished to the Securities and Exchange
Commission by the Registrant pursuant to Section 13 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; and

                    (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 undersigned Registrant hereby undertakes that, for
purposes of determining any liability under the Securities Act, each filing of
the Registrant's annual report pursuant to Section 13(a) or 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 that time
shall be deemed to be the initial bona fide offering thereof.

               C.   Insofar as indemnification for liabilities arising under
the Securities Act may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the provisions described under Item 6
above or otherwise, the Registrant has been advised that in the opinion of the
Securities and Exchange 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 Registrant of expenses incurred or paid by a director,
officer or controlling person of the Registrant in the successful defense of
any action, suit or proceeding) is asserted by


                                       4
<PAGE>   5

such director, officer or controlling person in connection with the securities
being registered, the Registrant 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.

                                    PART II
               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

                             INTRODUCTORY STATEMENT

         This Registration Statement on Form S-8 (the "Registration Statement")
of USA Networks, Inc., a Delaware corporation (the "Company" or the
"Registrant"), relates to up to 20,000,000 shares of the Registrant's common
stock, par value $.01 per share (the "Common Stock"), issuable in connection
with the USA Networks, Inc. 2000 Stock and Annual Incentive Plan (the "Plan").

                ITEM 3. INCORPORATION OF DOCUMENTS BY REFERENCE.

         The documents listed below are incorporated by reference in this
Registration Statement. All documents filed by the Company pursuant to Sections
13(a), 13(c), 14 and 15(d) of the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), subsequent to the date of the filing of this Registration
Statement and prior to the filing of a post-effective amendment that indicates
that all securities registered hereunder have been sold, or that deregisters
all securities then remaining unsold, shall be deemed to be incorporated by
reference in this Registration Statement and to be a part hereof from the date
of the filing of such documents.

               (a)  The Company's Annual Report on Form 10-K for the fiscal
year ended December 31, 1999;

               (b)  The description of the Common Stock is contained in the
Company's Proxy Statement on Schedule 14A, dated November 20, 1996.

               ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         The Registrant's Restated Certificate of Incorporation limits, to the
maximum extent permitted by Delaware law, the personal liability of directors
for monetary damages for breach of their fiduciary duties as directors. The
Registrant's Bylaws provide that the directors, officers and certain other
persons will be indemnified to the fullest extent permitted by Delaware law
with respect to third-party actions or suits, provided such person has met the
applicable standard of conduct which permits indemnification under Delaware
law. The Registrant's Bylaws further provide that directors, officers and
certain other persons will be indemnified with respect

                                       2
3

to actions or suits initiated by such person, provided that such proceeding was
authorized by the Board of Directors. The Registrant's Bylaws allow the
Registrant to pay all expenses incurred by a director, officer, employee or
agent in defending any proceeding within the scope of the indemnification
provisions as such expenses are incurred in advance of its final disposition,
subject to repayment if it is ultimately determined that such party was not
entitled to indemnity by the Registrant. From time to time, officers and
directors may be provided with indemnification agreements that are consistent
with the foregoing provisions. The Registrant believes that these agreements
are necessary to attract and retain qualified persons as directors and
officers.

         Section 145 of the Delaware General Corporation Law provides that a
corporation may indemnify a director, officer, employee or agent made a party
to an action by reason of the fact that he was a director, officer or agent of
the corporation or was serving at the request of the corporation against
expenses actually and reasonably incurred by him in connection with such action
if he acted in good faith and in a manner he reasonably believed to be in, or
not opposed to, the best interests of the corporation and, with respect to any
criminal action, had no reasonable cause to believe his conduct was unlawful.

         Insofar as indemnification for liabilities arising under the
Securities Act of 1933, as amended (the "Securities Act"), may be permitted to
directors, officers or persons controlling the Registrant pursuant to the
foregoing provisions, the Registrant has been advised that in the opinion of
the Securities and Exchange Commission, such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable.

         ITEM 8.   EXHIBITS.

         The exhibits incorporated by reference or filed as part of this
Registration Statement are listed in the Index of Exhibits that begins on page
9.

         ITEM 9.   UNDERTAKINGS.

               A.   The undersigned Registrant 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 of
1933, as amended (the "Securities Act");

                                       3
4

(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;
and (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 clauses (i) and (ii) do not apply if the information required to
be included in a post-effective amendment by those clauses is contained in
periodic reports filed with or furnished to the Securities and Exchange
Commission by the Registrant pursuant to Section 13 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; and

                    (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 undersigned Registrant hereby undertakes that, for
purposes of determining any liability under the Securities Act, each filing of
the Registrant's annual report pursuant to Section 13(a) or 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 that time
shall be deemed to be the initial bona fide offering thereof.

               C.   Insofar as indemnification for liabilities arising under
the Securities Act may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the provisions described under Item 6
above or otherwise, the Registrant has been advised that in the opinion of the
Securities and Exchange 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 Registrant of expenses incurred or paid by a director,
officer or controlling person of the Registrant in the successful defense of
any action, suit or proceeding) is asserted by

                                       4
5

such director, officer or controlling person in connection with the securities
being registered, the Registrant 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.
