ITEM 1.       DESCRIPTION OF REGISTRANT'S SECURITIES TO BE REGISTERED.

      The securities of InterActiveCorp, a Delaware corporation ("IAC"), to be
registered pursuant to Section 12(g) of the Securities Exchange Act of 1934, as
amended, are warrants ("IAC Warrants") to purchase 1.93875 shares of common
stock, par value $0.01 per share, of IAC ("IAC Common Stock") to be issued,
together with shares of IAC Common Stock, pursuant to the terms of the Agreement
and Plan of Merger, dated as of March 18, 2003, by and among USA Interactive
(now IAC), Equinox Merger Corp. and Expedia, Inc. ("Expedia"). A description of
the IAC Warrants is set forth under the caption "DESCRIPTION OF IAC LISTED
WARRANTS" in the proxy and information statement/prospectus forming a part of
the Registration Statement on Form S-4 of IAC (Registration No. 333-104973),
filed with the Securities and Exchange Commission on May 2, 2003, as amended on
July 9, 2003 and August 6, 2003, and as may be further amended (the
"Registration Statement"), which is incorporated herein by reference.

IAC Warrants
------------

      EXISTING IAC WARRANTS

      IAC currently has outstanding listed warrants to acquire IAC Common Stock
that were issued to former shareholders of Expedia that elected to receive IAC
securities in the IAC acquisition of control of Expedia in February 2002
("Existing IAC Warrants"). Similar to the IAC Warrants, the Existing IAC
Warrants are exercisable up to and including February 4, 2009. The Existing IAC
Warrants are quoted on the Nasdaq National Market under the symbol "IACIW" and
differ from the IAC Warrants. As a result, following the completion of the
merger, IAC will have two types of warrants quoted on the Nasdaq National
Market: the Existing IAC Warrants, which are quoted on the Nasdaq National
Market under the symbol "IACIW," and the IAC Warrants, which are expected to be
quoted on the Nasdaq National Market under the symbol "IACIZ"--with differing
terms, including vesting schedules with respect to the IAC Employee Warrants (as
defined below), differing exercise prices and differing shares of IAC Common
Stock issuable in respect of each such warrant.

      IAC STOCKHOLDER WARRANTS

      IAC stockholder warrants ("IAC Stockholder Warrants" which, together with
the IAC Employee Warrants defined below, constitute the IAC Warrants) will be
issued under a stockholder equity warrant agreement between IAC and Mellon
Investor Services LLC, the warrant agent.

      Each IAC Stockholder Warrant entitles its holder to purchase 1.93875
shares of IAC Common Stock. The exercise price per IAC Stockholder Warrant is
$26.00, which must be paid in cash. Each IAC Stockholder Warrant may be
exercised on any business day up to and including February 4, 2009. Any IAC
Stockholder Warrant not exercised before that date will become void, and all
rights of the holder of the IAC Stockholder Warrant will cease. Holders of IAC
Stockholder Warrants will not be entitled, by virtue of being such holders, to
have any rights of holders of IAC Common Stock until they exercise their
warrants. The IAC Stockholder Warrants are not subject to redemption.

      The number of shares of IAC Common Stock issuable upon exercise of the IAC



Stockholder Warrants will be subject to adjustment from time to time upon the
occurrence of any of the following events: any stock split; any stock
consolidation, combination or subdivision; any stock dividend or other
distribution; and any repurchase, reclassification, recapitalization or
reorganization; and certain distributions of rights, warrants or evidences of
indebtedness or assets.

      IAC will not issue fractional shares of IAC Common Stock upon exercise of
an IAC Stockholder Warrant. Instead of issuing a fractional share of IAC Common
Stock which would otherwise be deliverable upon the exercise of an IAC
Stockholder Warrant, IAC will pay the holder of such IAC Stockholder Warrant an
amount in cash based on the closing price of IAC Common Stock as of the exercise
date of the IAC Stockholder Warrant.

      IAC will not issue physical paper certificates representing the IAC
Stockholder Warrants unless requested in writing by the holder of the IAC
Stockholder Warrant. Instead, the warrant agent will issue the certificates in
electronic book entry form and will monitor the issuance and trading of such
warrants through its electronic book entry system, provided that IAC may
instruct the warrant agent to issue physical certificates if a holder's IAC
Stockholder Warrants are below a de minimis amount.

      IAC will keep in reserve at all times before the expiration date of the
IAC Stockholder Warrants sufficient authorized but unissued shares of IAC Common
Stock for issuance in the event of exercises by the holders of IAC Stockholder
Warrants.

      IAC EMPLOYEE WARRANTS

      The IAC employee warrants ("IAC Employee Warrants") will be issued under
an optionholder equity warrant agreement between IAC and Mellon Investor
Services LLC, the warrant agent. Except with respect to vesting (including
transferability prior to vesting), as described below, and applicable
withholding taxes, the IAC Employee Warrants are identical in all material
respects to the IAC Stockholder Warrants described above.

      The IAC Employee Warrants will be subject to the same vesting schedule as
the Expedia options in respect of which such Expedia Employee Warrants were
issued, which Expedia options will be converted into IAC options at the
completion of the merger. The IAC Employee Warrants will be forfeited and will
never become exercisable or transferable if an IAC option issued in exchange for
the Expedia option related to the former Expedia Employee Warrant never vests.
The IAC Employee Warrants to be issued in respect of Expedia Employee Warrants
will not be subject to redemption.

      IAC will not issue physical paper certificates representing the IAC
Employee Warrants. Instead, the warrant agent will issue the certificates in
electronic book entry form and will monitor the issuance, vesting and trading of
such warrants through its electronic book entry system, provided that IAC may
instruct the warrant agent to issue physical certificates if a holder's vested
IAC Employee Warrants are below a de minimis amount.

      IAC will keep in reserve at all times before the expiration date of the
IAC Employee Warrants sufficient authorized but unissued shares of IAC Common
Stock for issuance in the event of exercises by the holders of vested IAC
Employee Warrants.
