                     19,954,028 SHARES OF USA COMMON STOCK

    This prospectus relates to the resale of up to 19,954,028 shares of common
stock, par value $0.01 per share ("USA common stock"), of USA Interactive
(formerly USA Networks, Inc., "USA") that the selling stockholders named in this
prospectus in the section "SELLING STOCKHOLDERS" including their respective
affiliates, whom we refer to in this document as the "Selling Stockholders", may
offer from time to time. Affiliates of a selling stockholder include any person
directly controlling, controlled by, or under common control with the selling
stockholder. With respect to a selling stockholder that is a fund or account,
the term affiliate refers to any fund or account managed on a discretionary
basis by the same manager that manages the selling stockholder. The USA common
stock being offered by this prospectus was acquired by the Selling Stockholders
from Paul G. Allen, a director of USA, on or about May 7, 2002 in private resale
transactions.

    USA will not receive any proceeds from the sale of USA common stock by the
Selling Stockholders.

    The Selling Stockholders (directly, or through agents or dealers designated
from time to time) may sell the USA common stock being offered by this
prospectus from time to time on terms to be determined at the time of sale. The
prices at which these stockholders may sell the shares will be determined by the
prevailing market price for the shares or in negotiated transactions. This
offering will not be underwritten. To the extent required, the number of shares
of USA common stock to be sold, purchase price, public offering price, the names
of any such agent or dealer and any applicable commission or discount with
respect to a particular offering will be set forth in an accompanying prospectus
supplement. The aggregate proceeds to the Selling Stockholders from the sale of
the USA common stock being offered by this prospectus will be the purchase price
thereof less the aggregate agents' or dealers' commissions and discounts, if
any, and other expenses of distribution not borne by USA. The Selling
Stockholders will pay all applicable stock transfer taxes, brokerage
commissions, discounts or commissions and fees of the Selling Stockholders'
counsel. USA has agreed to pay certain expenses in connection with the filing of
the registration statement, of which this prospectus is a part, with the
Securities and Exchange Commission, and to indemnify the Selling Stockholders
against certain liabilities, including certain liabilities under the Securities
Act of 1933, as amended (the "Securities Act"), in connection with the
registration and offering of the USA common stock being offered by this
prospectus. See "PLAN OF DISTRIBUTION" on page 11.

    The Selling Stockholders and any agents, dealers or broker-dealers that
participate with the Selling Stockholders in the distribution of the USA common
stock being offered by this prospectus may be deemed to be "underwriters" within
the meaning of the Securities Act, and any commissions received by them and any
profit on the resale of the securities purchased by them may be deemed to be
underwriting commissions or discounts under the Securities Act.

    USA common stock is quoted on The Nasdaq National Market under the symbol
"USAI." On May 24, 2002, the last reported sale price of USA common stock was
$29.05 per share.

                             ABOUT THIS PROSPECTUS

    This prospectus is part of a registration statement that we are filing with
the Securities and Exchange Commission (the "SEC") on behalf of the Selling
Stockholders utilizing a "shelf" registration process. Under this shelf process,
the Selling Stockholders may, from time to time over approximately the next two
years, sell the shares of USA common stock being offered under this prospectus
in one or more offerings.

    This prospectus provides you with a general description of the securities
that the Selling Stockholders may offer. To the extent required, the number of
shares of USA common stock to be sold, purchase price, public offering price,
the names of any such agent or dealer and any applicable commission or discount
with respect to a particular offering by any Selling Stockholders will be set
forth in an accompanying prospectus supplement. You should read both this
prospectus and any prospectus supplement together with the additional
information described in the section "WHERE YOU CAN FIND MORE INFORMATION" on
page 4.

    You should rely only on the information provided in this prospectus and in
any prospectus supplement, including the information incorporated by reference.
We have not authorized anyone to provide you with different information. The
Selling Stockholders are not offering the USA common stock being offered under
this prospectus in any state where the offer is not permitted. You should not
assume that the information in this prospectus, or any supplement to this
prospectus, is accurate at any date other than the date indicated on the cover
page of these documents.

          CAUTIONARY STATEMENT CONCERNING FORWARD-LOOKING INFORMATION

    This prospectus and the SEC filings that are incorporated by reference into
this prospectus contain "forward-looking statements" within the meaning of the
securities laws. These forward-looking statements include, but are not limited
to, statements relating to our anticipated financial performance, business

and/or statements preceded by, followed by or that include the words "believes,"
"could," "expects," "anticipates," "estimates," "intend," "plans," "projects,"
"seeks," or similar expressions. We have based these forward-looking statements
on our current expectations and projections about future events, based on the
information currently available to us. For those statements, we claim the
protection of the safe harbors for forward-looking statements contained in the
Private Securities Litigation Reform Act of 1995. These forward-looking
statements are subject to risks, uncertainties and assumptions, including those
described in the section "RISK FACTORS," that may affect the operations,
performance, development and results of our business. You are cautioned not to
place undue reliance on these forward-looking statements, which speak only as of
the date stated, or if no date is stated, as of the date of this prospectus.

    You should understand that the following important factors, in addition to
those discussed in the documents incorporated in this prospectus by reference,
could affect our future results and could cause those results to differ
materially from those expressed in such forward-looking statements:

    - material adverse changes in economic conditions generally or in our
      markets;

    - future regulatory and legislative actions and conditions affecting our
      operating areas;

    - competition from others;

    - successful integration of our divisions' management structures;

    - product demand and market acceptance;

    - the ability to protect proprietary information and technology or to obtain
      necessary licenses on commercially reasonable terms;

                                       2

    - the ability to expand into and successfully operate in foreign markets;

    - obtaining and retaining key executives and employees; and

    - other risks and uncertainties as may be detailed from time to time in our
      public announcements and filings with the SEC.

    We undertake no obligation to publicly update or revise any forward-looking
statements, whether as a result of new information, future events or any other
reason. In light of these risks, uncertainties and assumptions, the
forward-looking events discussed in this prospectus may not occur.

                                    SUMMARY

    THIS SUMMARY HIGHLIGHTS SELECTED INFORMATION FROM THIS PROSPECTUS AND MAY
NOT CONTAIN ALL THE INFORMATION THAT MAY BE IMPORTANT TO YOU. TO UNDERSTAND THE
TERMS OF THE USA COMMON STOCK BEING OFFERED BY THIS PROSPECTUS, YOU SHOULD READ
THIS ENTIRE PROSPECTUS AND THE DOCUMENTS IDENTIFIED UNDER THE CAPTION "WHERE YOU
CAN FIND MORE INFORMATION." IN THIS PROSPECTUS, THE TERMS "USA", "WE" AND "OUR"
REFER TO USA INTERACTIVE (FORMERLY USA NETWORKS, INC.) AND OUR SUBSIDIARIES,
EXCEPT WHERE IT IS CLEAR THAT SUCH TERMS MEAN ONLY USA INTERACTIVE.

USA INTERACTIVE

    USA (Nasdaq: USAI) is focused on integrating interactive assets across
multiple lines of business. We believe USA is a leader in integrated
interactivity, including ticketing, online travel, online dating, electronic
retailing, teleservices and other interactive commerce services. USA consists of
Home Shopping Network (including HSN International and HSN Interactive);
Ticketmaster (Nasdaq: TMCS), which operates Ticketmaster, Ticketmaster.com,
Citysearch and Match.com; Expedia, Inc. (Nasdaq: EXPE); Hotels.com (Nasdaq:
ROOM); TV Travel Group Limited; Electronic Commerce Solutions; Precision
Response Corporation; and Styleclick.

    On May 7, 2002, USA contributed all of its entertainment businesses to
Vivendi Universal Entertainment LLLP (the "VUE transaction"), a new joint
venture controlled by Vivendi Universal, S.A. ("Vivendi"). Immediately following
such transaction, USA was renamed USA Interactive.

    USA's business is primarily focused on its electronic commerce and
interactive/information service businesses, and USA expects that it will
actively seek to grow those businesses, including through acquisitions. Any such
acquisitions could involve the issuance of additional USA securities or cash or
a combination of securities and cash. In addition, USA is no longer required to
obtain the consent of Vivendi, Liberty Media Corporation ("Liberty") or
Mr. Diller as USA stockholders for any such acquisitions regardless of the size
of such acquisitions except in the event that USA is highly leveraged, in which
case each of Mr. Diller and Liberty will have the right to consent to specified
contingent matters involving USA. USA is continually reviewing, and often in
discussions with third parties regarding, such possible growth opportunities,
including transactions in the online and offline travel services and
commerce-related areas.

    USA is incorporated under the laws of the State of Delaware. USA's executive
offices are located at 152 West 57th Street, New York, New York 10019 and our
telephone number is (212) 314-7300.

                                  RISK FACTORS

    AN INVESTMENT IN OUR SECURITIES INVOLVES A HIGH DEGREE OF RISK. YOU SHOULD
CONSIDER THE FOLLOWING FACTORS CAREFULLY BEFORE DECIDING TO PURCHASE OUR
SECURITIES. ADDITIONAL RISKS NOT PRESENTLY KNOWN TO US OR THAT WE CURRENTLY DEEM
IMMATERIAL MAY ALSO IMPAIR OUR BUSINESS OPERATIONS.

WE DEPEND ON OUR KEY PERSONNEL

    We are dependent upon the continued contributions of our senior corporate
management, particularly Mr. Diller, and certain key employees for our future
success. Mr. Diller is our Chairman of the Board and Chief Executive Officer.
Mr. Diller does not have an employment agreement with us, although he has been
granted options to purchase a substantial number of shares of USA common stock.

    If Mr. Diller no longer serves in his positions at USA, our business, as
well as the market price of USA common stock, could be substantially adversely
affected. We cannot assure you that we will be able to retain the services of
Mr. Diller or any other of our members of senior management or key employees.

WE ARE CONTROLLED BY MR. DILLER AND IN HIS ABSENCE, WILL BE CONTROLLED BY
  LIBERTY

    Mr. Diller, through entities he controls, currently beneficially owns or has
the right to vote 100% of the shares of our Class B common stock, par value $.01
per share, which is sufficient to control the outcome of any matter submitted to
a vote or for the consent of our shareholders with respect to which holders of
USA common stock, USA Class B common stock and USA preferred stock vote together
as a single class. Mr. Diller, subject to the terms of an amended and restated
stockholders agreement, dated as of December 16, 2001 (the "Stockholders
Agreement"), among Universal Studios, Liberty, Mr. Diller, USA and Vivendi,
effectively controls the outcome of all matters submitted to a vote or for the
consent of our stockholders (other than with respect to the election by the
holders of USA common stock of 25% of the members of our board of directors
(rounded up to the nearest whole number) and certain matters as to which a
separate class vote of the holders of USA common stock or USA preferred stock is
required under Delaware law).

    Under the Stockholders Agreement, each of Mr. Diller and Liberty have the
right to consent to certain contingent matters in the event that USA is highly
leveraged. We cannot assure you that Mr. Diller and Liberty will agree in the
future on any transaction or action relating to a contingent matter at a time
when USA is highly leveraged, in which case we would not be able to engage in
such transaction or take such action.

    Upon Mr. Diller's permanent departure from USA, generally, Liberty would be
able to control USA through its ownership of its USA Class B common stock.

                                USE OF PROCEEDS

    All of the USA common stock being offered under this prospectus is being
sold by the Selling Stockholders. USA will not receive any proceeds from the
sale of USA common stock by the Selling Stockholders.

USA'S RELATIONSHIPS WITH THE SELLING STOCKHOLDERS

    The USA common stock being offered under this prospectus by the Selling
Stockholders was acquired by such Selling Stockholders from Paul G. Allen, who
is a director of USA, on or about May 7, 2002 in private resale transactions.

    In connection with the acquisition by the Selling Stockholders of the USA
common stock being offered under this prospectus, we and the Selling
Stockholders entered into two registration rights agreements (each, a
"Registration Rights Agreement" and collectively, the "Registration Rights
Agreements"), pursuant to which we granted registration rights relating to the
USA common stock being offered under this prospectus. Pursuant to these
Registration Rights Agreements, USA filed a registration statement, of which
this prospectus is a part, with respect to the USA common stock subject to this
prospectus on May 22, 2002. The Registration Rights Agreements are filed as
exhibits to that registration statement and incorporated herein by reference.

    One or more of the Selling Stockholders may have engaged in transactions
with USA in the ordinary course of business of USA and such Selling
Stockholders, all of which transactions have been negotiated at arms-length.

                              PLAN OF DISTRIBUTION

METHOD OF SALE

    The Selling Stockholders may sell the USA common stock being offered under
this prospectus directly to other purchasers, or to or through broker-dealers or
agents, in separate transactions or in a single transaction. To the extent
required, the number of shares of USA common stock to be sold, purchase price,
public offering price, the names of any such agent or dealer and any applicable
commission or discount with respect to a particular offering will be set forth
in an accompanying prospectus supplement.

    The shares of USA common stock being offered under this prospectus may be
sold from time to time by the Selling Stockholders in any of the following ways:

    - The USA common stock may be sold through a broker or brokers, acting as
      principals or agents. Transactions through broker-dealers may include
      block trades in which brokers or dealers will attempt to sell the USA
      common stock as agent but may position and resell the block as principal
      to facilitate the transaction. The USA common stock may be sold through
      dealers or agents or to dealers acting as market makers. Broker-dealers
      may receive compensation in the form of discounts, concessions, or
      commissions from the Selling Stockholders and/or the purchasers of the USA
      common stock for whom such broker-dealers may act as agents or to whom
      they sell as principal, or both (which compensation as to a particular
      broker-dealer might be in excess of customary commissions).

    - The USA common stock may be sold on any national securities exchange or
      quotation service on which the USA common stock may be listed or quoted at
      the time of sale, in the over-the-counter market, or in transactions
      otherwise than on such exchanges or services or in the over-the-counter
      market.

                                       11

    - The USA common stock may be sold in private sales directly to purchasers.

    The Selling Stockholders may enter into hedging transactions with
counterparties (including broker-dealers), and the counterparties may engage in
short sales of the USA common stock in the course of hedging the positions they
assume with the Selling Stockholders, including, without limitation, in
connection with distribution of the USA common stock by such counterparties.
Such counterparties may receive compensation in the form of underwriting
discounts, concessions or commissions from the Selling Stockholders or the
purchasers of the USA common stock for whom they may act as agents. In addition,
the Selling Stockholders may sell short the USA common stock, and in such
instances, this prospectus may be delivered in connection with such short sales
and the USA common stock offered hereby may be used to cover such short sales.
The Selling Stockholders may also enter into option or other transactions with
counterparties that involve the delivery of the USA common stock to the
counterparties, who may then resell or otherwise transfer such USA common stock.

    The Selling Stockholders may also loan or pledge the USA common stock and
the borrower or pledgee may sell the USA common stock as loaned or upon a
default may sell or otherwise transfer the pledged USA common stock.

    USA common stock covered by this prospectus which qualifies for sale
pursuant to Rule 144 of the Securities Act may be sold under Rule 144 rather
than pursuant to this prospectus.

    The Selling Stockholders reserve the right to accept and, together with
their agents from time to time, to reject, in whole or in part, any proposed
purchase of USA common stock to be made directly or through agents.

    In order to comply with securities laws in certain jurisdictions, the USA
common stock being offered by this prospectus will be offered or sold in such
jurisdictions only through registered or licensed brokers or dealers. In
addition, in certain jurisdictions the securities offered hereby may not be
offered or sold unless they have been registered or qualified for sale in such
jurisdictions or an exemption from registration or qualification is available
and is complied with.

TIMING AND PRICE

    The shares of USA common stock being offered under this prospectus may be
sold from time to time by the Selling Stockholders. See "SELLING
STOCKHOLDERS--USA'S RELATIONSHIPS WITH THE SELLING STOCKHOLDERS". There is no
assurance that the Selling Stockholders will sell or dispose of any or all of
their shares of USA common stock.

    Under the Registration Rights Agreements entered into with the Selling
Stockholders, we are required to keep the registration statement of which this
prospectus is a part effective until the earlier of the date on which the
Selling Stockholders no longer hold the USA common stock or May 2, 2004.

    The Selling Stockholders will be subject to applicable provisions of the
Exchange Act and the rules and regulations thereunder, which provisions may
limit the timing of purchases and sales of USA common stock by them.

    The USA common stock being offered under this prospectus may be sold at a
fixed price, which may be changed, or at varying prices determined at the time
of sale or at negotiated prices. Such prices will be determined by the holders
of such securities or by agreement between such holders and purchasers and/or
dealers (who may receive fees or commissions in connection therewith).

PROCEEDS, COMMISSIONS AND EXPENSES

    The aggregate proceeds to the Selling Stockholders from the sale of the USA
common stock offered by them under this prospectus will be the purchase price of
such USA common stock less

                                       12

discounts, concessions and commissions, if any. USA will not receive any

expenses and costs incurred by us in connection with the preparation of the
registration statement of which this prospectus is a part and in complying with
all applicable securities and blue sky laws.

    The Selling Stockholders and any broker-dealers or agents that participate
with the Selling Stockholders in the distribution of the USA common stock may be
deemed to be "underwriters" within the meaning of the Securities Act, and any
commissions received by them and any profit on the resale of the USA common
stock may be deemed to be underwriting commissions or discounts under the
Securities Act.

    Under the Registration Rights Agreements described above, USA has agreed to
indemnify the Selling Stockholders against certain liabilities, including
certain liabilities arising under the Securities Act. The Selling Stockholders
may agree to indemnify any agent, dealer or broker-dealer that participates in
transactions involving sales of the USA common stock against certain
liabilities, including liabilities arising under the Securities Act.

NASDAQ LISTING STATUS

    USA common stock is currently listed on the Nasdaq National Market under the
symbol "USAI."

                        DESCRIPTION OF USA COMMON STOCK

    Set forth below is a description of the USA common stock being offered under
this prospectus. The following statements are brief summaries of, and are
subject to the provisions of, our restated certificate of incorporation, as
amended, our amended and restated by-laws, and the relevant provisions of the
General Corporation Law of the State of Delaware.

    As of the date of this prospectus, our authorized capital stock consists of
1,600,000,000 shares of USA common stock, par value $0.01 per share, 400,000,000
shares of USA Class B common stock, par value $0.01 per share, and 100,000,000
shares of preferred stock, par value $0.01 per share. As of May 10, 2002, there
were 350,252,365 shares of USA common stock outstanding, 63,033,452 shares of
USA Class B common stock outstanding and 13,120,533 shares of USA preferred
stock outstanding.

    With respect to matters that may be submitted to a vote or for the consent
of our stockholders generally, including the election of directors, each holder
of USA common stock, USA Class B common stock and USA preferred stock will vote
together as a single class. In connection with any such vote, each holder of USA
common stock is entitled to one vote for each share of USA common stock held,
each holder of USA Class B common stock is entitled to ten votes for each share
of USA Class B common stock held and each holder of USA preferred stock is
entitled to two votes for each share of USA preferred stock held.
Notwithstanding the foregoing, the holders of USA common stock, acting as a
single class, are entitled to elect 25% of the total number of our directors,
and, in the event that 25% of the total number of directors shall result in a
fraction of a director, then the holders of USA common stock, acting as a single
class, are entitled to elect the next higher whole number of directors. In
addition, Delaware law requires that certain matters be approved by the holders
of USA common stock voting as a separate class.

    Shares of USA Class B common stock are convertible into shares of USA common
stock at the option of the holder thereof, at any time, on a share-for-share
basis. Such conversion ratio will in all events be equitably preserved in the
event of any recapitalization of USA by means of a stock dividend

                                       13

on, or a stock split or combination of, outstanding USA common stock or USA
Class B common stock, or in the event of any merger, consolidation or other
reorganization of USA with another corporation. Upon the conversion of USA
Class B common stock into shares of USA common stock, those shares of USA
Class B common stock will be retired and will not be subject to reissue. Shares
of USA common stock are not convertible into shares of USA Class B common stock.

    In all other respects, the USA common stock and the USA Class B common stock
are identical. The holders of USA common stock and the holders of USA Class B
common stock are entitled to receive, share for share, such dividends as may be
declared by our board of directors out of funds legally available therefor. In
the event of a liquidation, dissolution, distribution of assets or winding-up of
USA, the holders of USA common stock and the holders of USA Class B common stock
are entitled to share ratably in all assets of USA available for distribution to
our stockholders, after the rights of the holders of the USA preferred stock,
have been satisfied.

    In connection with our acquisition of USA Network and Studios USA in 1998,
we granted to Liberty preemptive rights to acquire shares of USA stock. These
preemptive rights, which were amended in connection with the VUE transaction,
generally provide that Liberty may elect to purchase a number of shares of USA
stock so that the percentage equity interest Liberty owned of us immediately
after a transaction would be the same as immediately before such transaction, in
each case, assuming the exchange of all shares of Home Shopping Network owned by
a subsidiary of Liberty. The purchase price for shares of USA stock pursuant to
a preemptive right election is the fair market value of the USA stock purchased.

    Our certificate of incorporation provides that there can be no stock
dividends or stock splits or combinations of stock declared or made on USA
common stock or USA Class B common stock unless the shares of USA common stock
and USA Class B common stock then outstanding are treated equally and
identically.

    In connection with the acquisition of a controlling interest in
Expedia, Inc., USA issued an aggregate of approximately 13,125,000 shares of its
preferred stock, par value $0.01 per share, "Series A Cumulative Convertible
Preferred Stock," each having a $50.00 face value and a term of 20 years, which
we refer to in this prospectus as USA preferred stock. Each share of USA
preferred stock is convertible, at the option of the holder at any time, into
that number of shares of USA common stock equal to the quotient obtained by
dividing $50 by the conversion price per share of USA common stock (as defined
in the certificate of designation for the USA preferred stock). In the event of
a voluntary or involuntary liquidation, dissolution or winding up of USA,
holders of USA preferred stock shall be entitled to receive, in preference to
any holder of USA common shares, an amount per share equal to all accrued and
unpaid dividends plus the greater of (a) face value, or (b) the liquidating
distribution that would be received had such holder converted the USA preferred
stock into USA common stock immediately prior to the liquidation, dissolution or
winding up of USA.

    The arrangements described in this prospectus in the section "RISK FACTORS",
and more fully described in the documents identified under the caption "WHERE
YOU CAN FIND MORE INFORMATION", may have the effect of delaying, deferring or
preventing a change in control of USA.

    The transfer agent for the shares of USA common stock and USA preferred
stock is The Bank of New York.

    The shares of USA common stock being offered under this prospectus have been
legally issued, are fully paid and are non-assessable.

                                       14

            CERTAIN MATERIAL UNITED STATES FEDERAL TAX CONSEQUENCES

GENERAL

    The following is a general discussion of certain material United States
federal income and estate tax consequences of the ownership and disposition of
USA common stock.

    As used herein, a "United States person" is

    - a citizen or resident of the United States;

    - a corporation created or organized in the United States or under the laws
      of the United States or of any state;

    - an estate the income of which is includible in gross income for United
      States federal income taxation regardless of its source;

    - a trust if a court in the United States is able to exercise primary
      supervision over the administration of the trust and one or more United
      States persons have the authority to control all substantial decisions of
      the trust; or

    - any person otherwise subject to United States federal income tax on a net
      income basis in respect of its worldwide taxable income.

    A "U.S. Holder" is a beneficial owner of USA common stock who is a United
States person. A "Non-U.S. Holder" is a beneficial owner that is not a U.S.
Holder.

    This discussion is based on current law, which is subject to change,
possibly with retroactive effect, or different interpretations. This discussion
is limited to holders who hold USA common stock as capital assets. Moreover,
this discussion is for general information only and does not address all the tax
consequences that may be relevant in light of your particular circumstances, nor
does it discuss special tax provisions which may apply if you have relinquished
United States citizenship or residence.

    EACH PROSPECTIVE PURCHASER IS ADVISED TO CONSULT A TAX ADVISOR WITH RESPECT
TO CURRENT AND POSSIBLE FUTURE TAX CONSEQUENCES OF PURCHASING, OWNING AND
DISPOSING OF OUR COMMON STOCK, AS WELL AS ANY TAX CONSEQUENCES THAT MAY ARISE
UNDER STATE, LOCAL, FOREIGN OR OTHER TAX LAWS.

TAXATION OF U.S. HOLDERS

    This section describes the tax consequences to a U.S. Holder. If you are not
a U.S. Holder, this section does not apply to you.

    DISTRIBUTIONS.  Distributions on USA common stock will constitute dividend
income, taxable at ordinary income rates, to the extent of USA's current or
accumulated earnings and profits. Any excess will be treated as non-taxable
return of capital to the extent of the holder's basis in the common stock, and
thereafter as capital gain.

    SALES OR EXCHANGES.  On the sale, exchange or other disposition of shares of
USA common stock (other than a redemption of the common stock, discussed below),
holders will generally recognize capital gain or loss equal to the difference
between the sale proceeds and the adjusted tax basis in the stock sold,
exchanged or disposed of. This gain or loss will be long-term capital gain or
loss if at the time of the sale, exchange or disposition the holder has held the
stock sold, exchanged or disposed of for more than one year. The deductibility
of capital losses is subject to limitations.

    DIVIDENDS TO CORPORATE SHAREHOLDERS.  In general, a distribution on the USA
common stock that is taxable as a dividend and that is made to a corporate
shareholder will qualify for the 70% corporate

                                       15

dividends-received deduction under the Internal Revenue Code. However, a
dividend that arises upon a redemption of common stock will generally constitute
an "extraordinary dividend" under Section 1059 of the Internal Revenue Code. In
addition, constructive dividends received on common stock within two years of
the holder's acquisition of the stock may also constitute "extraordinary
dividends." If the extraordinary dividend rules apply, the corporate shareholder
may lose some or all of the benefits of the dividends-received deduction.
Furthermore, there are many exceptions and restrictions relating to the
availability of the dividends-received deduction. Consequently, corporate
shareholders should consult their own tax advisors regarding the extent, if any,
that the dividends-received deduction is available to them and the extent to
which the extraordinary dividend rules may apply.

    REDEMPTION OF USA COMMON STOCK.  A redemption of USA common stock generally
would be a taxable event and would be treated as if the holder sold the common
stock if the redemption:

    - results in a "complete termination" of the holder's interest in USA stock;

    - is "substantially disproportionate" (i.e., after the redemption, the
      percentage of all our outstanding voting stock that is owned by the holder
      is less than 80% of the percentage of all our outstanding voting stock
      (and the percentage of all our outstanding common stock that is owned by
      the holder is less than 80% of the percentage of all our outstanding
      common stock) that was owned by the holder immediately before the
      redemption); or

    - is "not essentially equivalent to a dividend" (i.e., the redemption must
      meaningfully reduce the holder's proportionate interest in USA based on
      the holder's particular circumstance; the Internal Revenue Service (the
      "IRS") has indicated that this test is satisfied by even a small reduction
      in the percentage interest of a shareholder whose relative stock interest
      in a publicly held corporation is minimal and who exercises no control
      over corporate affairs).

    In determining whether any of these tests has been met, holders must take
into account the shares of stock actually owned and the shares of stock
constructively owned by reason of certain constructive ownership rules set forth
in Section 318 of the Internal Revenue Code.

    If stock is redeemed in a redemption that meets one of the tests described
above, the holder generally would recognize taxable gain or loss equal to the
difference between the amount of cash and the fair market value of property
received and the holder's tax basis in the stock redeemed. This gain or loss
would be long-term capital gain or capital loss if the stock were held for more
than one year.

    If a redemption does not meet any of the tests described above, the entire
amount of the cash and the fair market value of property received generally
would be taxed as a dividend as explained above under "Distributions." If a
redemption is treated as a distribution that is taxable as a dividend, the
holder's basis in the redeemed stock would generally be transferred to the
holder's remaining shares of stock, if any.

    INFORMATION REPORTING AND BACKUP WITHHOLDING.  Information reporting will
generally apply to dividends received on USA common stock and to the proceeds
received on the sale or disposition of such stock by a U.S. Holder who is not an
exempt recipient. Generally, individuals are not exempt recipients, whereas
corporations are exempt recipients. Backup withholding will apply only if the
U.S. Holder is not an exempt recipient and:

    - fails to furnish its Taxpayer Identification Number ("TIN") which, in the
      case of an individual, is his or her Social Security Number;

    - furnishes an incorrect TIN;

    - in the case of dividends, is notified by the IRS that it has failed to
      properly report payments of interest or dividends; or

                                       16

    - fails to certify, under penalty of perjury, that it has furnished a
      correct TIN, has not been notified by the IRS that it is subject to backup
      withholding (or has since been notified by the IRS that it is no longer
      subject to backup withholding) and is a U.S. person (including a U.S.
      resident alien).

    U.S. Holders should consult their tax advisors regarding their qualification
for exemption from backup withholding and the procedure for demonstrating such
an exemption if applicable.

    The amount of any backup withholding from a payment to a U.S. Holder is not
an additional tax and is allowable as a credit against the U.S. Holder's United
States federal income tax liability, if any, or may be claimed as a refund,
provided that the required information is furnished to the IRS.

TAXATION OF NON-U.S. HOLDERS

    This section describes the tax consequences to a Non-U.S. Holder. If you are
a U.S. Holder, see the above discussion under "Taxation of U.S. Holders."

    DIVIDENDS.  If dividends are paid, Non-U.S. Holders will be subject to
withholding of United States federal income tax at a 30% rate or a lower rate as
may be specified by an applicable income tax treaty. To claim the benefit of a
lower rate under an income tax treaty, Non-U.S. Holders must properly file with
the payor an IRS Form W-8BEN, or successor form, claiming an exemption from or
reduction in withholding under the applicable tax treaty. In addition, where
dividends are paid or deemed paid to a Non-U.S. Holder that is a partnership or
other pass through entity, persons holding an interest in the entity may need to
provide certification claiming an exemption or reduction in withholding under
the applicable treaty.

    If actual or deemed dividends are considered effectively connected with the
conduct of a trade or business within the United States and, where a tax treaty
applies, are attributable to a United States permanent establishment, those
dividends will not be subject to withholding tax, but instead will be subject to
United States federal income tax on a net basis at applicable graduated
individual or corporate rates, provided an IRS Form W-8ECI, or successor form,
is filed with the payor. In the case of a foreign corporation, any effectively
connected dividends may, under certain circumstances, be subject to an
additional "branch profits tax" at a rate of 30% or a lower rate as may be
specified by an applicable income tax treaty.

    Non-U.S. Holders must comply with the certification procedures described
above, or, in the case of payments made outside the United States with respect
to an offshore account, certain documentary evidence procedures, directly or
under certain circumstances through an intermediary, to obtain the benefits of a
reduced rate under an income tax treaty with respect to dividends paid or deemed
paid with respect to USA common stock. In addition, if a Non-U.S. Holder is
required to provide an IRS Form W-8ECI or successor form, as discussed above,
the Non-U.S. Holder must also provide its tax identification number.

    Non-U.S. Holders that are eligible for a reduced rate of United States
withholding tax pursuant to an income tax treaty may obtain a refund of any
excess amounts withheld by filing an appropriate claim for refund with the IRS.

    GAIN ON DISPOSITION OF USA COMMON STOCK.  Non-U.S. Holders generally will
not be subject to United States federal income tax on any gain realized on the
sale or other disposition of USA common stock unless:

    - the gain is considered effectively connected with the conduct of a trade
      or business within the United States and, where a tax treaty applies, is
      attributable to a United States permanent establishment (and, in which
      case, if the holder is a foreign corporation, may be subject to an

                                       17

      additional "branch profits tax" equal to 30% or a lower rate as may be
      specified by an applicable income tax treaty);

    - the holder is an individual who holds the USA common stock as a capital
      asset and is present in the United States for 183 or more days in the
      taxable year of the sale or other disposition and other conditions are
      met; or

    - we are or have been a "United States real property holding corporation,"
      or a USRPHC, for United States federal income tax purposes. We believe
      that we are not currently, and are not likely to become, a USRPHC. If we
      were to become a USRPHC, then gain on the sale or other disposition of USA
      common stock generally would not be subject to United States federal
      income tax provided:

       - USA common stock were "regularly traded" on an established securities
         market; and

       - the holder did not actually or constructively own more than 5% of the
         USA common stock during the shorter of the five-year period preceding
         the disposition or the holder's holding period.

    FEDERAL ESTATE TAX.  In the case of an individual, USA common stock held at
the time of death will be included in the individual's gross estate for United
States federal estate tax purposes, and may be subject to United States federal
estate tax, unless an applicable estate tax treaty provides otherwise.

    INFORMATION REPORTING AND BACKUP WITHHOLDING.  We must report annually to
the IRS and to each holder the amount of dividends paid or deemed paid and the
tax withheld with respect to those dividends, regardless of whether withholding
was required. Copies of the information returns reporting those dividends and
withholding may also be made available to the tax authorities in the country in
which a Non-U.S. Holder resides under the provisions of an applicable income tax
treaty or other applicable agreements.

    Backup withholding is generally imposed on certain payments to persons that
fail to furnish the necessary identifying information to the payor. Generally
Non-U.S. Holders will be subject to back-up withholding tax with respect to
dividends paid on USA common stock unless they certify their status as Non-U.S.
Holders.

    The payment of proceeds of a sale of USA common stock effected by or through
a United States office of a broker will be subject to both backup withholding
and information reporting unless the holder provides the payor with the holder's
name and address and certifies its Non-U.S. Holder status or otherwise
establishes an exemption. In general, backup withholding and information
reporting will not apply to the payment of the proceeds of a sale of USA common
stock by or through a foreign office of a broker. If, however, such broker is,
for United States federal income tax purposes, a United States person, a
controlled foreign corporation, a foreign person that derives 50% or more of its
gross income for certain periods from the conduct of a trade or business in the
United States, or, a foreign partnership that at any time during its tax year
either is engaged in the conduct of a trade or business in the United States or
has as partners one or more United States persons that, in the aggregate, hold
more than 50% of the income or capital interest in the partnership, such
payments will be subject to information reporting, but not backup withholding,
unless such broker has documentary evidence in its records that the holder is a
Non-U.S. Holder and certain other conditions are met or the holder otherwise
establishes an exemption.

    Any amounts withheld under the backup withholding rules generally will be
allowed as a refund or a credit against the holder's United States federal
income tax liability provided the required information is furnished in a timely
manner to the IRS.
