                          AGREEMENT AND PLAN OF MERGER

               THIS AGREEMENT AND PLAN OF MERGER (this "Agreement") is dated as
of March 20, 1998, by and among USA NETWORKS, INC., a Delaware corporation
("Parent"), BRICK ACQUISITION CORP., an Illinois corporation and a wholly owned
subsidiary of Parent ("Sub"), and TICKETMASTER GROUP, INC., an Illinois
corporation (the "Company").

                                    RECITALS:

               A. The Boards of Directors of Parent, Sub and the Company have
each approved the terms and conditions of the business combination between
Parent and the Company to be effected by the merger (the "Merger") of Sub with
and into the Company, pursuant to the terms and subject to the conditions of
this Agreement and the Business Corporation Act of the State of Illinois (the
"Illinois Statute"), and each deems the Merger advisable and in the best
interests of each corporation. A Special Committee of the Board of Directors of
the Company (the "Special Committee") has determined that the Merger is fair to,
and in the best interests of, the holders of shares of common stock, no par
value, of the Company ("Company Common Stock"), other than Parent and its
subsidiaries, and has recommended to the Board of Directors of the Company that
it approve the terms and conditions of the Merger, including this Agreement. The
Disinterested Directors (as defined in Section 5/7.85 of the Illinois Statute)
of the Company have approved the terms and conditions of the Merger.

               B. Each of Parent, Sub and the Company desires to make certain
representations, warranties, covenants and agreements in connection with the
Merger.

               C. For federal income tax purposes, it is intended that the
Merger and the transactions contemplated thereby qualify as a reorganization
under the provisions of Section 368(a) of the United States Internal Revenue
Code of 1986, as amended (the "Code").

               D. It was a condition, which condition was satisfied, to the
willingness of Parent and Sub to enter into this Agreement and to consummate the
transactions contemplated hereby (the "Transactions"), including the acquisition
of the stock of the Company in the Merger from the Company's shareholders,
including the Chief Executive Officer, that the Chief Executive Officer of the
Company entered into that certain agreement with Parent, dated March 9, 1998
(the "Cooperation Agreement"), pursuant to which, among other things, such
individual agreed not to compete with, or to solicit customers of, the Company
from and after the expiration of his current employment agreement with the
Company and to cooperate with the Company and Parent to provide for an orderly
transition to a new Chief Executive Officer of the Company.

               NOW, THEREFORE, in consideration of the premises and mutual
covenants and agreements contained in this Agreement, the parties agree as
follows:

               SECTION 1.2. EFFECTIVE TIME OF THE MERGER. Subject to the
provisions of this Agreement, the Merger shall become effective (the "Effective

agreed upon by the parties, which date shall be no later than the third Business

Corporation, and (b) the Merger shall have all of the effects provided by the
Illinois Statute.

               SECTION 1.5. CERTIFICATE OF INCORPORATION AND BYLAWS OF SURVIVING

shall continue as the officers of the Surviving Corporation until such time as
their respective successors are duly elected as provided in the bylaws of the
Surviving Corporation.

                                    ARTICLE 2

                EFFECT OF THE MERGER ON THE CAPITAL STOCK OF THE
               CONSTITUENT CORPORATIONS; EXCHANGE OF CERTIFICATES

SECTION 2.1 EFFECT OF MERGER ON CAPITAL STOCK. At the Effective Time, subject
and pursuant to the terms of this Agreement, by virtue of the Merger and without
any action on the part of the Constituent Corporations or the holders of any
shares of capital stock of the Constituent Corporations:

               (a) Capital Stock of Sub. Each issued and outstanding share of
        the common stock, $.01 par value per share, of Sub ("Sub Common Stock")
        shall be converted into one validly issued, fully paid and nonassessable
        share of common stock, $.01 par value per share, of the Surviving
        Corporation ("Surviving Corporation Common Stock"). Each stock
        certificate of Sub evidencing ownership of any such shares shall
        continue to evidence ownership of such shares of Surviving Corporation
        Common Stock.

               (b) Treatment of Certain Shares of Company Common Stock. Each
        share of Company Common Stock that is owned by the Company as treasury
        stock and each share of Company Common Stock that is owned by Parent,
        Sub or any other wholly owned subsidiary of Parent shall not be
        cancelled and retired and shall be treated as provided in Section
        2.1(c). 

               (c) Exchange Ratio for Company Common Stock. Each share of
        Company Common Stock issued and outstanding immediately prior to the
        Effective Time (other than shares of Company Common Stock held by
        shareholders who properly demand dissenters' rights in accordance with
        Section 5/11.70 of the Illinois Statute), shall, subject to Section
        2.1(d), be converted into the right to receive 1.126 of a fully paid and
        nonassessable share of common stock, $.01 par value per share, of Parent
        ("Parent Common Stock") (the "Exchange Ratio"). At the Effective Time,
        all such shares of Company Common Stock shall no longer be outstanding,
        and shall automatically be cancelled and retired and cease to exist, and
        each holder of a certificate representing any such shares shall cease to
        have any rights with respect thereto, except the right to receive the
        shares of Parent Common Stock to be issued in consideration therefor
        upon the surrender of such certificate in accordance with Section 2.2,
        without interest. No fractional shares of Parent Common Stock shall be
        issued; and, in lieu thereof, a cash payment shall be made pursuant to
        Section 2.2(e).

               (d) Adjustment of Exchange Ratio for Dilution and Other Matters.
        If, between the date of this Agreement and the Effective Time, the
        outstanding shares of Parent Common Stock shall have been changed into a
        different number of shares or a different class by reason of any
        reclassification, recapitalization, split-up, stock dividend, stock

                                      -3-
<PAGE>   10

        combination, exchange of shares, readjustment or otherwise, then the
        Exchange Ratio, as the case may be, shall be correspondingly adjusted.
        Without otherwise limiting the foregoing, the Exchange Ratio of 1.126
        set forth in paragraph (c) above gives effect to the two-for-one stock
        split declared by the Company on February 20, 1998, with respect to the
        Parent Common Shares (as defined in Section 4.3). 

               SECTION 2.2. EXCHANGE OF CERTIFICATES.

               (a) Exchange Agent. Prior to the Closing Date, Parent shall
select a bank or trust company reasonably acceptable to the Company to act as
exchange agent (the "Exchange Agent") in the Merger. Prior to the Effective
Time, Parent shall deposit with the Exchange Agent, for the benefit of the
holders of shares of Company Common Stock, for exchange in accordance with this
Article 2, certificates representing the shares of Parent Common Stock (such
shares of Parent Common Stock, together with any dividends or distributions with
respect thereto, the "Exchange Fund") issuable pursuant to Section 2.1(c) at the
Effective Time in exchange for outstanding shares of Company Common Stock, which
shall include such shares of Parent Common Stock to be sold by the Exchange
Agent pursuant to Section 2.2(e).

               (b) Exchange Procedures. As soon as practicable after the
Effective Time, Parent shall instruct the Exchange Agent to mail to each holder
of record (other than the Company, Parent, Sub and any wholly owned subsidiary
of the Company) of a certificate or certificates which immediately prior to the
Effective Time represented issued and outstanding shares of Company Common Stock
(collectively, the "Certificates") whose shares were converted into the right to
receive Parent Common Stock pursuant to Section 2.1(c), (i) a letter of
transmittal (which shall specify that delivery shall be effected, and risk of
loss and title to the Certificates shall pass, only upon delivery of the
Certificates to the Exchange Agent and shall be in such form and have such other
provisions as Parent and the Company may reasonably specify) and (ii)
instructions for use in effecting the surrender of the Certificates in exchange
for certificates representing Parent Common Stock and any cash in lieu of
fractional shares of Parent Common Stock. Upon surrender of a Certificate for
cancellation to the Exchange Agent, together with a duly executed letter of
transmittal and such other documents as may be reasonably required by the
Exchange Agent, the holder of such Certificate shall be entitled to receive in
exchange therefor a certificate representing that number of whole shares of
Parent Common Stock which such holder has the right to receive pursuant to the
provisions of this Article 2 and any cash in lieu of fractional shares of Parent
Common Stock, and the Certificate so surrendered shall forthwith be cancelled.
In the event of a transfer of ownership of shares of Company Common Stock which
is not registered on the transfer records of the Company, a certificate
representing the proper number of shares of Parent Common Stock and any cash in
lieu of fractional shares of Parent Common Stock may be issued and paid to a
transferee if the Certificate representing such Company Common Stock is
presented to the Exchange Agent, accompanied by all documents required to
evidence and effect such transfer and by evidence that any applicable stock
transfer taxes have been paid. Until surrendered as contemplated by this Section
2.2, each Certificate shall be deemed, on and after the Effective Time, to
represent only the right to receive upon such surrender the certificate
representing shares of Parent Common Stock and cash in lieu of any fractional
shares of Parent Common Stock as contemplated by this Article 2 and the Illinois


                                      -4-


<PAGE>   11

Statute. The consideration to be issued in the Merger will be delivered by the
Exchange Agent as promptly as practicable following surrender of a Certificate
and any other required documents. No interest will be payable on such
consideration regardless of any delay in making payments. 

               (c) Distributions with Respect to Unsurrendered Certificates. No
dividends or other distributions declared or made after the Effective Time with
respect to Parent Common Stock with a record date after the Effective Time shall
be paid to the holder of any unsurrendered Certificate with respect to the
shares of Parent Common Stock represented thereby, and no cash payment in lieu
of fractional shares shall be paid to any such holder pursuant to Section 2.2(e)
until the holder of record of such Certificate shall surrender such Certificate.
Subject to the effect, if any, of applicable laws, following surrender of any
such Certificate, there shall be paid to the record holder of the certificates
representing whole shares of Parent Common Stock issued in exchange therefor or
such holder's transferee pursuant to Section 2.2(e), without interest, (i) at
the time of such surrender, the amount of any cash payable in lieu of a
fractional share of Parent Common Stock to which such holder is entitled
pursuant to Section 2.2(e) and the amount of dividends or other distributions on
Parent Common Stock with a record date after the Effective Time theretofore paid
with respect to such whole shares of Parent Common Stock, and (ii) at the
appropriate payment date, the amount of dividends or other distributions on
Parent Common Stock with a record date after the Effective Time but prior to
surrender and a payment date subsequent to surrender payable with respect to
such whole shares of Parent Common Stock.

               (d) No Further Ownership Rights in Company Common Stock. All
shares of Parent Common Stock issued upon the surrender for exchange of shares
of Company Common Stock in accordance with the terms of this Article 2 (plus any
cash paid pursuant to Section 2.2(c) or 2.2(e)) shall be deemed to have been
issued (and paid) in full satisfaction of all rights pertaining to such shares
of Company Common Stock. From and after the Effective Time, the stock transfer
books of the Company shall be closed with respect to the shares of Company
Common Stock, and there shall be no further registration of transfers on the
stock transfer books of the Company or the Surviving Corporation of the shares
of Company Common Stock which were outstanding immediately prior to the
Effective Time. If, after the Effective Time, Certificates are presented to the
Surviving Corporation for any reason, they shall be cancelled and exchanged as
provided in this Article 2.

               (e) No Issuance of Fractional Shares. 

                      (i) No certificates or scrip for fractional shares of
        Parent Common Stock shall be issued upon the surrender for exchange of
        Certificates, and such fractional share interests will not entitle the
        owner thereof to vote or to any rights of a shareholder of Parent.

                      (ii) As promptly as practicable following the Effective
        Time, the Exchange Agent shall determine the excess of (A) the number of
        full shares of Parent Common Stock delivered to the Exchange Agent by
        Parent pursuant to Section 2.2(a) over (B) the aggregate number of full
        shares of Parent Common Stock to be distributed to holders 

                                      -5-


<PAGE>   12

        of Company Common Stock pursuant to Section 2.2(b) (such excess, the
        "Excess Shares"). As soon after the Effective Time as practicable, the
        Exchange Agent, as agent for the holders of Company Common Stock, shall
        sell the Excess Shares at then prevailing prices in the over-the-counter
        market, all in the manner provided in clause (iii) of this
        Section 2.2(e).

                      (iii) The sale of the Excess Shares by the Exchange Agent
        shall be executed in the over-the-counter market through one or more
        member firms of the National Association of Securities Dealers, Inc.
        (the "NASD") and shall be executed in round lots to the extent
        practicable. Until the net proceeds of such sale or sales have been
        distributed to the holders of Company Common Stock, the Exchange Agent
        will hold such proceeds in trust for the holders of Company Common Stock
        (the "Common Shares Trust"). Parent shall pay all commissions, transfer
        taxes and other out-of-pocket transaction costs, including the expenses
        and compensation of the Exchange Agent incurred in connection with such
        sale of the Excess Shares. The Exchange Agent shall determine the
        portion of the Common Shares Trust to which each holder of Company
        Common Stock shall be entitled, if any, by multiplying the amount of the
        aggregate net proceeds comprising the Common Shares Trust by a fraction,
        the numerator of which is the amount of the fractional share interest to
        which such holder of Company Common Stock is entitled and the
        denominator of which is the aggregate amount of fractional share
        interests to which all holders of Company Common Stock are entitled.

                      (iv) As soon as practicable after the determination of the
        amount of cash, if any, to be paid to the holders of Company Common
        Stock in lieu of any fractional share interests and subject to clause
        (v) of this Section 2.2(e), the Exchange Agent shall make available such
        amounts to such holders of Company Common Stock.

                      (v) Parent or the Exchange Agent shall be entitled to
        deduct and withhold from the consideration otherwise payable pursuant to
        this Agreement to any holder of shares of Company Common Stock such
        amounts as Parent or the Exchange Agent is required to deduct and
        withhold with respect to the making of such payment under the Code, or
        any provision of state, local or foreign tax law. To the extent that
        amounts are so withheld by Parent or the Exchange Agent, such withheld
        amounts shall be treated for all purposes of this Agreement as having
        been paid to the holder of the shares of Company Common Stock in respect
        of which such deduction and withholding was made by Parent or the
        Exchange Agent.

               (f) Termination of Exchange Fund. Any portion of the Exchange
Fund and Common Shares Trust which remains undistributed to the shareholders of
the Company for 12 months after the Effective Time shall be delivered to Parent,
upon demand, and any former shareholders of the Company who have not theretofore
complied with this Article 2 shall thereafter look only to Parent for payment of
their claim for Parent Common Stock, any cash in lieu of fractional shares of
Parent Common Stock and any dividends or distributions with respect to Parent
Common Stock.


                                      -6-

<PAGE>   13

               (g) No Liability. Neither the Exchange Agent, Parent, Sub nor the
Company shall be liable to any holder of shares of Company Common Stock or
Parent Common Stock, as the case may be, for shares (or dividends or
distributions with respect thereto) from the Exchange Fund or cash from the
Common Shares Trust delivered to a public official pursuant to any applicable
abandoned property, escheat or similar law.

               (h) Lost, Stolen or Destroyed Certificates. In the event any
Certificates evidencing shares of Company Common Stock shall have been lost,
stolen or destroyed, the holder of such lost, stolen or destroyed Certificate(s)
shall execute an affidavit of that fact upon request. The holder of any such
lost, stolen or destroyed Certificate(s) shall also deliver a reasonable
indemnity against any claim that may be made against Parent or the Exchange
Agent with respect to the Certificate(s) alleged to have been lost, stolen or
destroyed. The affidavit and any indemnity which may be required hereunder shall
be delivered to the Exchange Agent, who shall be responsible for making payment
for such lost, stolen or destroyed Certificate(s).

               SECTION 2.3. STOCK OPTIONS. At the Effective Time, the Company's
obligation with respect to each outstanding option (each, a "Company Option") to
purchase shares of Company Common Stock issued pursuant to the Company's Stock
Plan (the "Stock Plan") and (unless otherwise elected by the optionee pursuant
to the terms of an individual agreement) pursuant to the Stock Option Agreement,
dated as of December 15, 1993, between the Company and Fredric D. Rosen (the
"Rosen Option"), as amended in the manner described in the following sentence,
shall be assumed by Parent. The Company Options so assumed by Parent shall
continue to have, and be subject to, the same terms and conditions as set forth
in the Stock Plan and the Rosen Option and the agreements pursuant to which such
Company Options were issued as in effect immediately prior to the Effective
Time, which plan, agreements and Rosen Option shall be assumed by Parent, except
that (in accordance with the applicable provisions of such plan and Rosen Option
and subject to any other rights that a holder of Company Options may have) (a)
each such Company Option shall be exercisable for that number of whole shares of
Parent Common Stock equal to the product of that number of shares of Company
Common Stock covered by such Company Option immediately prior to the Effective
Time multiplied by the Exchange Ratio and rounded up to the nearest whole number
of shares of Parent Common Stock, and (b) the exercise price per share of Parent
Common Stock shall equal the exercise price per share of Company Common Stock in
effect immediately prior to the Effective Time divided by the Exchange Ratio.
The adjustment provided herein with respect to any Company Options which are
"Incentive Stock Options" (as defined in Section 422 of the Code) shall be and
is intended to be effected in a manner which is consistent with Section 424(a)
of the Code. Parent shall reserve for issuance the number of shares of Parent
Common Stock that will become issuable upon the exercise of such Company Options
pursuant to this Section 2.3.

               SECTION 2.4. TAKING OF NECESSARY ACTION; FURTHER ACTION. If, at
any time after the Effective Time, any such further action is necessary or
desirable to carry out the purposes of this Agreement or to vest, perfect or
confirm of record or otherwise establish in the Surviving Corporation full
right, title and interest in, to or under any of the assets, property, rights,
privileges, powers and franchises of the Company and Sub, the officers and
directors of the 

                                      -7-
<PAGE>   14
Surviving Corporation are fully authorized in the name and on behalf of each of
the Constituent Corporations or otherwise to take all such lawful and necessary
or desirable action.

                                    ARTICLE 3

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

               The Company represents and warrants to Parent and Sub as follows:

SECTION 3.1. ORGANIZATION AND QUALIFICATION; SUBSIDIARIES. Each of the Company
and its "Significant Subsidiaries" (as such term is defined in Regulation S-X
promulgated by the Securities and Exchange Commission (the "SEC")) is a
corporation or other entity duly incorporated or organized, validly existing
and, as applicable, in good standing under the laws of the jurisdiction of its
incorporation or organization and has the requisite corporate or other power and
authority to own, lease and operate its assets and properties and to carry on
its business as it is now being conducted. Each of the Company and its
subsidiaries is in possession of all franchises, grants, authorizations,
licenses, permits, easements, consents, certificates, approvals and orders
("Approvals") necessary to own, lease and operate the properties it purports to
own, operate or lease and to carry on its business as it is now being conducted,
except where the failure to have such Approvals would not, individually or in
the aggregate, have a Material Adverse Effect (as defined below). Each of the
Company and its subsidiaries is, as applicable, duly qualified or licensed as a
foreign corporation to do business, and is in good standing, in each
jurisdiction where the character of the properties owned, leased or operated by
it or the nature of its business makes such qualification or licensing
necessary, except for such failures to be so duly qualified or licensed and in
good standing that would not, either individually or in the aggregate, have a
Material Adverse Effect. When used in this Article 3 or elsewhere in this
Agreement in connection with the Company or any of its subsidiaries, the term
"Material Adverse Effect" means any change, event or effect that is materially
adverse to the business, financial condition or results of operations of the
Company and its subsidiaries taken as a whole, excluding (i) any changes or
effects resulting from any matter, which matter was expressly approved by the
Board of Directors of the Company following the date hereof unless, with respect
to such matter, both directors of the Company who are also executive officers of
Parent either voted against or abstained from voting (such matter and related
contemplated transactions, an "Approved Matter") and (ii) changes in general
economic conditions in the economy as a whole. Other than wholly owned
subsidiaries and except as disclosed in the Company SEC Reports or Section 3.1
of the Company Disclosure Letter, the Company does not directly or indirectly
own any equity or similar interest in, or any interest convertible or
exchangeable or exercisable for any equity or similar interest in, any
corporation, partnership, limited liability company, joint venture or other
business, association or entity. As used in this Agreement, "subsidiary" with
respect to any person shall mean any entity which such person has the ability to
control the voting power thereof, either through ownership of equity interests
or otherwise, provided that under no circumstances shall the Company and its
subsidiaries be deemed to be subsidiaries of Parent.

<PAGE>   15

               SECTION 3.2. CERTIFICATE OF INCORPORATION AND BYLAWS. The Company
has previously furnished or made available to Parent a complete and correct copy
of its Articles of Incorporation and Bylaws as amended to date. Such Articles of
Incorporation and bylaws are in full force and effect. Neither the Company nor
any of its Significant Subsidiaries is in violation of any of the provisions of
its certificate of incorporation or bylaws or equivalent organizational
documents.

               SECTION 3.3. CAPITALIZATION. The authorized capital stock of the
Company consists of 80,000,000 shares of Company Common Stock and 20,000,000
shares of Company Preferred Stock. At the close of business on March 9, 1998,
(a) 26,176,265 shares of Company Common Stock were issued and outstanding, all
of which are validly issued, fully paid and nonassessable, and not subject to
preemptive rights, (b) of the amount referred to in clause (a) above, no shares
of Company Common Stock were held in treasury by the Company or by wholly owned
subsidiaries of the Company, (c) options to purchase 2,658,086 and 1,331,340
shares of Company Common Stock were outstanding under the Stock Plan and the
Rosen Option, and (d) 237,346 shares of Company Common Stock were reserved for
issuance to the former owners of the Company's Canadian subsidiary. As of the
date hereof, no shares of Company Preferred Stock were issued or outstanding. No
change in such capitalization has occurred between March 9, 1998 and the date
hereof, except (i) the issuance of shares of Company Common Stock pursuant to
the exercise of outstanding options and (ii) as contemplated by this Agreement.
Except as set forth in this Section 3.3 or as disclosed in Section 3.3 of the
disclosure letter delivered by the Company to Parent (the "Company Disclosure
Letter"), as of the date of this Agreement, there are no options, warrants or
other rights, agreements, or commitments, in each case to which the Company or
any of its subsidiaries is a party, of any character relating to the issued or
unissued capital stock of the Company or any of its subsidiaries or obligating
the Company or any of its subsidiaries to issue or sell any shares of capital
stock of, or other equity interests in, the Company or any of its subsidiaries.
All shares of Company Common Stock subject to issuance as aforesaid, upon
issuance on the terms and conditions specified in the instruments pursuant to
which they are issuable, shall be duly authorized, validly issued, fully paid
and nonassessable and not subject to preemptive rights. Except as set forth in
Section 3.3 of the Company Disclosure Letter, there are no obligations,
contingent or otherwise, of the Company or any of its subsidiaries to
repurchase, redeem or otherwise acquire any shares of Company Common Stock or
the capital stock of any subsidiary or to provide funds to or make any material
investment (in the form of a loan, capital contribution or otherwise) in any
such subsidiary or any other entity other than guarantees of obligations of
subsidiaries entered into in the ordinary course of business. All of the
outstanding equity interests of each of the Company's subsidiaries are duly
authorized, validly issued, and, where applicable, fully paid and nonassessable,
and, except as set forth in Section 3.3 of the Company Disclosure Letter or (in
the case of subsidiaries of the Company only) for such matters as would not,
individually or in the aggregate, have a Material Adverse Effect, all such
shares are owned by the Company or another subsidiary free and clear of all
security interests, liens, claims, pledges, agreements, limitations in the
Company's voting rights, charges or other encumbrances of any nature whatsoever.

               SECTION 3.4. AUTHORITY RELATIVE TO THIS AGREEMENT; BOARD
                            APPROVAL.

               (a) The Company has all necessary corporate power and authority
to execute and deliver this Agreement and to perform its obligations hereunder
and, subject to obtaining the approval of the shareholders of the Company of
this Agreement, to consummate the Transactions. The execution and delivery of
this Agreement by the Company and the consummation by the Company of the
Transactions have been duly and validly authorized by all necessary corporate
action on the part of the Company and no other corporate proceedings on the part
of the Company are necessary to authorize this Agreement or to consummate the
Transactions so contemplated (other than, with respect to the Merger, the
approval and adoption of this Agreement by the vote of shareholders of the
Company owning at least a majority of the outstanding shares of Company Common
Stock in accordance with the Illinois Statute and the Company's Articles of
Incorporation and Bylaws, which vote is the only vote required to consummate the
Transactions under the Company's Articles of Incorporation and the Illinois
Statute). This Agreement has been duly and validly executed and delivered by the
Company and, assuming the due authorization, execution and delivery by Parent
and Sub, constitutes the legal and binding obligation of the Company,
enforceable against the Company in accordance with its terms, subject to (i)
bankruptcy, insolvency, reorganization, moratorium or other similar laws
affecting or relating to creditors rights generally and (ii) the availability of
injunctive relief and other equitable remedies. The Company has taken all
appropriate actions so that the restrictions on business combinations contained
in Section 5/11.75 of the Illinois Statute will not apply to Parent or Sub and
their respective affiliates and associates with respect to or as a result of
this Agreement or the Transactions.

               (b) The Board of Directors of the Company based on the
recommendation of the Special Committee (which recommendation was a condition to
the approval of the Company's Board of Directors set forth in clause (i) of this
sentence) has, prior to this Agreement, (i) approved this Agreement and the
Transactions (including for purposes of the Illinois Statute), (ii) determined
that the Transactions are fair to and in the best interests of the shareholders
of the Company and (iii) recommended that the shareholders of the Company
approve this Agreement and the Transactions. This Agreement and the Transactions
have been approved by the vote of at least two-thirds of the Disinterested
Directors (as defined in Section 5/7.85 of the Illinois Statute), and no vote of
Company shareholders pursuant to Section 5/7.85 of the Illinois Statute is
required in connection with the Transactions.

               SECTION 3.5. NO CONFLICT; REQUIRED FILINGS AND CONSENTS.

               (a) The execution and delivery of this Agreement by the Company
do not, and the performance of its obligations hereunder and the consummation of
the Transactions by the Company will not, (i) conflict with or violate the
certificate of incorporation, bylaws or equivalent organizational documents of
the Company or any of its subsidiaries; (ii) subject to obtaining the approval
of the Company's shareholders of this Agreement in accordance with the Illinois
Statute and the Company's Articles of Incorporation and Bylaws and compliance
with the requirements set forth in Section 3.5(b), conflict with or violate any
law, rule, regulation, order, judgment or decree applicable to the Company or
any of its subsidiaries or by which any of their 

                                      -10-

respective properties is bound or affected; or (iii) except as set forth in
Section 3.5 of the Company Disclosure Letter, result in any breach of or
constitute a default (or an event that with notice or lapse of time or both
would become a default) under, or alter the rights or obligations of any third
party or the Company or its subsidiaries under, or give to others any rights of
termination, amendment, acceleration, increased payments or cancellation of, or
result in the creation of a lien or other encumbrance on any of the properties
or assets of the Company or any of its subsidiaries pursuant to, any note, bond,
mortgage, indenture, contract, agreement, lease, license, permit, franchise or
other instrument or obligation to which the Company or any of its subsidiaries
is a party or by which the Company or any of its subsidiaries or any of their
respective properties are bound or affected, except, in the case of clauses (ii)
and (iii) above, for any such conflicts, violations, breaches, defaults or other
alterations or occurrences that would not prevent or delay consummation of the
Merger in any material respect, or otherwise prevent the Company from performing
its obligations under this Agreement in any material respect, and would not
have, individually or in the aggregate, a Material Adverse Effect. Section 3.5
of the Company Disclosure Letter lists all material consents, waivers and
approvals under any agreements, contracts, licenses or leases required to be
obtained by the Company or its subsidiaries in connection with the consummation
of the Transactions.

               (b) The execution and delivery of this Agreement by the Company

the Transactions by the Company will not, require any consent, approval,
authorization or permit of, or registration or filing with or notification to,

of documents to satisfy the applicable requirements, if any, of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), and state takeover laws,
(ii) the filing with the SEC of a proxy statement and prospectus in definitive

respect the Company from performing its obligations under this Agreement or (B)
would not, individually or in the aggregate, have a Material Adverse Effect.

               SECTION 3.6. COMPLIANCE; PERMITS.

               SECTION 3.7. SEC FILINGS; FINANCIAL STATEMENTS.

               (a) The Company has made available to Parent a correct and

fact or omit to state a material fact necessary in order to make the statements
made, in light of the circumstances under which they were made, not misleading,
provided, however, that no representation is made with respect to information

requirements and with the published rules and regulations of the SEC with
respect thereto, had been prepared in accordance with generally accepted
accounting principles ("GAAP") applied on a consistent basis throughout the
periods involved (except as may be indicated in the notes thereto or, in the
case of the unaudited statements, as permitted by Form 10-Q or the Exchange Act
regulations promulgated by the SEC), and each fairly presented the consolidated
financial position of the Company and its consolidated subsidiaries in all

liabilities (absolute, accrued, contingent or otherwise) of a nature required to
be disclosed on a balance sheet or in the related notes to the consolidated
financial statements prepared in accordance with GAAP which are, individually or
in the aggregate, material to the business, results of operations or financial

its subsidiaries, taken as a whole or (iii) arising out of or incurred in
connection with (x) this Agreement or the transactions contemplated hereby or

its accounting methods, principles or practices except as required by concurrent
changes in GAAP.

               SECTION 3.9. ABSENCE OF LITIGATION. Except as disclosed in the

Securities Act, contain any untrue statement of a material fact or omit to state
any material fact required to be stated therein or necessary in order to make
the statements therein, in light of the circumstances under which they are made,
not misleading; and (b) the Proxy Statement will, at the date the Proxy

Exchange Act and the rules and regulations promulgated by the SEC thereunder.

               SECTION 3.11. BROKERS. Except as set forth in Section 3.11 of the

Salomon Smith Barney (f/k/a Salomon Brothers Inc) (the "Company Banker")) is
entitled to any brokerage, finder's or other fee or commission in connection
with the Merger and the Transactions based upon arrangements made by or on

Transactions.

               SECTION 3.12. OPINION OF FINANCIAL ADVISOR. The Special Committee

will be delivered to Parent.

               SECTION 3.13. EMPLOYEE BENEFIT PLANS. 

               (a) The Company has delivered or made available to Parent prior

other material written employee programs, arrangements or agreements, whether
arrived at through collective bargaining or otherwise, all material medical,
vision, dental or other health plans, all life insurance plans and all other
material employee benefit plans or fringe benefit plans, including, without
limitation, all "employee benefit plans" as that term is defined in Section 3(3)
of the Employee Retirement Income Security Act of 1974, as amended ("ERISA"),
currently adopted, maintained by, sponsored in whole or in part by, or
contributed to by the Company or any entity required to be aggregated with the

spouses, directors, independent contractors or other beneficiaries and under
which current or former employees, retirees, dependents, spouses, directors,
independent contractors or other beneficiaries are eligible to participate

               (d) Except as set forth in Section 3.13 of the Company Disclosure
Letter, as described in any Company SEC Reports or as provided under the Stock
Plan or any related agreement and the Rosen Option, neither the execution and
delivery of this Agreement nor the consummation of the Transactions (or any
termination of employment in connection with the Transactions) will (i) result
in any material payment becoming due to any current or former director or
employee of the Company or any of its affiliates from the Company or any of its
affiliates under any Company Benefit Plan or otherwise, (ii) materially increase
any benefits otherwise payable under any Company Benefit Plan or (iii) result in
any acceleration of the time of payment or vesting of any such benefits to any
material extent.

               SECTION 3.14. TAX MATTERS. Neither the Company nor any of its
subsidiaries has taken or agreed to take any action (including in connection
with the Transactions) that would prevent the Merger from constituting a
reorganization qualifying under the provisions of Section 368(a) of the Code.


                                    ARTICLE 4

                REPRESENTATIONS AND WARRANTIES OF PARENT AND SUB

               Parent and Sub jointly and severally represent and warrant to the
Company, as follows:

SECTION 4.1 ORGANIZATION AND QUALIFICATION; SUBSIDIARIES. Each of Parent and
its Significant Subsidiaries is a corporation or other entity duly organized,
validly existing and, as applicable, in good standing under the laws of the
jurisdiction of its incorporation or organization and has the requisite
corporate or other power and authority to own, lease and operate its assets and
properties and to carry on its business as it is now being conducted. Each of
Parent and its subsidiaries is in possession of all Approvals necessary to own,
lease and operate the properties it purports to own, operate or lease and to
carry on its business as it is now being conducted, except where the failure to
have such Approvals would not, individually or in the aggregate, have a Material
Adverse Effect (as defined below). Each of Parent and its subsidiaries is, as
applicable, duly qualified or licensed as a foreign corporation or other entity
to do business, and is in good standing, in each jurisdiction where the
character of the properties owned, leased or operated by it or the nature of its
business makes such qualification or licensing necessary, except for such
failures to be so duly qualified or licensed and in good standing that would
not, either individually or in the aggregate, have a Material Adverse Effect.
When used in this Article 4 or elsewhere in connection with Parent or any of its
subsidiaries, the term "Material Adverse Effect" means any change, event or
effect that is materially adverse to the business, financial condition or
results of operations of Parent and its subsidiaries (including USANi LLC, a
Delaware limited liability company) taken as a whole, excluding changes in
general economic conditions in the economy as a whole. Other than wholly owned
subsidiaries and except as disclosed in the Parent 

                                      -15-

certificate of incorporation or bylaws or equivalent organizational documents.

               SECTION 4.3. CAPITALIZATION. In each case without giving effect

with the Parent Common Stock, the "Parent Common Shares") and (b) 15,000,000
shares of preferred stock, par value $.01 per share, of Parent ("Parent

the close of business on March 11, 1998, (i) 51,089,631 shares of Parent Common

"Parent Proxy Statement"), not subject to any preemptive rights, (ii) no shares
of Parent Common Stock were held in treasury by Parent or by subsidiaries of
Parent, (iii) shares of USANi LLC exchangeable into 54,327,175 Parent Common
Shares were outstanding, and (iv) Home Shopping Network, Inc. shares
exchangeable into 7,905,016 shares of Parent Common Stock and 399,136 shares of

validly issued and are fully paid and nonassessable. Except as set forth in this
Section 4.3, the Parent Proxy Statement or as disclosed in the disclosure letter
delivered by Parent to the Company (the "Parent Disclosure Letter"), as of the

Parent or any of its subsidiaries. All shares of Parent Common Stock subject to
issuance as aforesaid, upon issuance on the terms and conditions specified in
the instruments pursuant to which they are issuable, shall, and the shares of
Parent Common Stock to be issued pursuant to the Merger will be, duly
authorized, validly issued, fully paid and nonassessable and not subject to
preemptive rights, except as set forth in the Parent Proxy Statement. Except as
set forth in the Parent Proxy Statement or Section 4.3 of the Parent Disclosure
Letter, there are no obligations, contingent or otherwise, of Parent or any of
its subsidiaries to repurchase, redeem or otherwise acquire any shares of Parent
Common Stock or the capital stock of any subsidiary or to provide funds to or
make any material investment (in the form of a loan, capital contribution or
otherwise) in any such subsidiary or any other entity other than guarantees of
obligations of subsidiaries entered into in the ordinary course of business. All
of the outstanding equity interests (other than directors' qualifying shares) of
each of Parent's subsidiaries are duly authorized, validly issued, and, where
applicable, fully paid and nonassessable and, except as set forth in the Parent
Proxy Statement or for such matters as would not, individually or in the
aggregate, have a Material Adverse Effect, all such shares (other than
directors' qualifying shares) are owned by Parent or another subsidiary. The
shares of Surviving Corporation Common Stock to be issued in the Merger will,
upon issuance, be validly issued, fully paid, nonassessable and free and clear

                            BOARD APPROVAL. 

               (a) Each of Parent and Sub has all necessary corporate power and
authority to execute and deliver this Agreement, and to perform its obligations
hereunder and to consummate the transactions contemplated hereby. The execution
and delivery of this Agreement by Parent and Sub and the consummation by Parent
and Sub of the Transactions have been duly and validly authorized by all
necessary corporate action on the part of Parent and Sub and no other corporate
proceedings on the part of Parent or Sub are necessary to authorize this
Agreement, or to consummate the Transactions (other than the approval of the
NASD listing application with respect to the issuance of shares of Parent Common
Stock in the Merger). This Agreement has been duly and validly executed and
delivered by Parent and Sub and, assuming the due authorization, execution and
delivery by the Company, constitutes the legal and binding obligations of Parent

similar laws affecting or relating to creditors rights generally and (ii) the
availability of injunctive relief and other equitable remedies.

subsidiaries under, or give to others any rights of termination, amendment,
acceleration, increased payments or cancellation of, or result in the creation

Parent or any of its subsidiaries or any of their respective properties are
bound or affected, except in the cases of clauses (ii) and (iii) above, for any
such conflicts, violations, breaches, defaults or other alterations or
occurrences that would not prevent or delay consummation of the Merger in any
material respect, or otherwise prevent Parent and Sub from performing their
respective obligations under this Agreement in any material respect, and would
not have, individually or in the aggregate, a Material Adverse Effect. Section
4.5(a) of the Parent Disclosure Letter lists all material consents, waivers and

takeover laws, (ii) the filing with the SEC of the Proxy Statement and the

approvals, authorizations or permits, or to make such filings or notifications
(A) would not prevent or delay consummation of the Merger in any material
respect or otherwise prevent or delay in any material respect Parent or Sub from
performing their respective obligations under this Agreement or (B) would not,
individually or in the aggregate, have a Material Adverse Effect.

               SECTION 4.6. COMPLIANCE; PERMITS.

               (a) Except as disclosed in Section 4.6 or Section 4.9 of the

variances, exemptions, orders and approvals from Governmental Entities which are
material to the operation of the business of Parent and its subsidiaries taken
as a whole (collectively, the "Parent Permits"). Parent and its subsidiaries are
in compliance with the terms of the Parent Permits, except where the failure to
so comply would not, individually or in the aggregate, have a Material Adverse
Effect.

               (a) Parent has made available to the Company a correct and
complete copy of each report, schedule, registration statement and definitive
proxy statement filed by Parent with the SEC on or after January 1, 1997 and

the forms, reports and documents required to be filed by Parent with the SEC
since January 1, 1997. As of their respective dates, the Parent SEC Reports and
any forms, reports and other documents filed by Parent and Sub after the date of

requirements and with the published rules and regulations of the SEC with

Form 10-Q or the Exchange Act regulations promulgated by the SEC) and each
fairly presented the consolidated financial position of Parent and its
consolidated subsidiaries in all material respects as at the respective dates
thereof and the consolidated results of its operations and cash flows for the

necessary to promptly cooperate with the other parties in obtaining) any
clearance, consent, authorization, order or approval of, or any exemption by,

               (b) Subject to the terms and conditions of this Agreement, each
of the parties shall use all reasonable efforts to take, or cause to be taken,
all actions and to do, or cause to be done, all things necessary, proper or

will, and will use its reasonable efforts to cause its officers to, cooperate
with a designated search committee of officers and/or directors of Parent
appointed by Parent to identify an appropriate successor Chief Executive Officer
for the Company in connection with the Merger. In the event that Parent believes
that the Company is not in compliance with the foregoing, Parent shall provide

may so comply by taking such action as such directors deem appropriate in their
good faith judgment.

               SECTION 5.8. CONSENTS. Parent, Sub and the Company shall each use
all reasonable efforts to obtain the consent and approval of, or effect the

former directors and officers of the Company, as such agreements relate to the
indemnification of such persons for expenses and liabilities arising from facts
or events which occurred on or before the Effective Time or relating to the
Merger or Transactions. In addition, Parent agrees to provide to the current
directors and officers of the Company the maximum indemnification protection
(including with respect to advancement of expenses) permitted under the Illinois
Statute. Parent agrees to cause the Company to have in effect, as of the
Effective Time and covering the six-year period following the Effective Time,
for the benefit of the Company's current and former directors and officers,
insurance in the same amount and on substantially the same terms as the
Company's current directors' and officers' policies with respect to acts or
omissions occurring on or prior to the Effective Time. 

               SECTION 5.12. NOTIFICATION OF CERTAIN MATTERS. Each of the
Company, Parent and Sub shall give prompt notice to the other such parties of
the occurrence, or failure to occur, of any event, which occurrence or failure
to occur would be likely to cause (a) any representation or warranty contained
in this Agreement to be untrue or inaccurate in any material respect at any time
from the date of this Agreement to the Effective Time, or (b) any material
failure of the Company, Parent, or Sub as the case may be, or of any officer,
director, employee or agent thereof, to comply with or satisfy any covenant,
condition or agreement to be complied with or satisfied by it under this
Agreement. Notwithstanding the foregoing, the delivery of any notice pursuant to
this Section shall not limit or otherwise affect the remedies available
hereunder to the party receiving such notice.

               SECTION 5.13. EMPLOYEE AGREEMENTS. From and after the Effective
Time, Parent shall cause the Surviving Corporation to fulfill all written
employment, severance, termination, consulting and retirement agreements, as in
effect on the date hereof, to which the Company or any of its subsidiaries is a
party, pursuant to the terms thereof and applicable law.

               SECTION 5.14. REORGANIZATION. From and after the date hereof,
each of Parent and the Company and their respective subsidiaries shall not, and
shall use reasonable efforts to cause their affiliates not to, take any action,
or fail to take any action, that would jeopardize qualification of the Merger as
a reorganization within the meaning of Section 368(a) of the Code or enter into
any contract, agreement, commitment or arrangement that would have such effect.

                                    ARTICLE 6

                              CONDITIONS PRECEDENT

               SECTION EXCHANGE 6.1. CONDITIONS TO EACH PARTY'S OBLIGATION TO
EFFECT THE MERGER. The respective obligations of each party to effect the Merger
are subject to the satisfaction prior to the Closing Date of the following
conditions:

               (a) Shareholder Approval. This Agreement shall have been approved
        and adopted by the requisite vote of the shareholders of the Company, in
        accordance with all applicable provisions of the Illinois Statute.

               (b) Effectiveness of the S-4. The S-4 shall have been declared
        effective by the SEC under the Securities Act and shall not be the
        subject of any stop order or proceeding by the SEC seeking a stop order.

               (c) Governmental Entity Approvals. All other material
        authorizations, consents, orders or approvals of, or declarations or
        filings with, or expiration of waiting periods imposed by, any
        Governmental Entity necessary for the Merger and the consummation of the
        Transactions shall have been filed, expired or been obtained, other than
        those that, individually or in the aggregate, the failure to be filed,
        expired or obtained would not, in the reasonable opinion of Parent, have
        a Material Adverse Effect on the Company or Parent.

               (d) No Injunctions or Restraints; Illegality. No temporary
        restraining order, preliminary or permanent injunction or other order
        issued by any court of competent jurisdiction or other legal restraint
        or prohibition preventing the consummation of the Merger or the other
        Transactions shall be in effect, nor shall any proceeding brought by an
        administrative agency or commission or other governmental authority or
        instrumentality, domestic or foreign, seeking any of the foregoing be
        pending or threatened; and there shall not be any action taken, or any
        statute, rule, regulation or order (whether temporary, preliminary or
        permanent) enacted, entered or enforced which makes the consummation of
        the Merger or the other Transactions illegal or prevents or prohibits
        the Merger or the other Transactions.

               (e) NASDAQ Quotation. The shares of Parent Common Stock issuable
        to the holders of the Company Common Stock pursuant to the Merger shall
        have been authorized for quotation on the NASD National Market (or other
        national market or 

                                      -29-

        Adverse Effect," shall be true and correct in all material respects (i)
        as of the date hereof and (ii) as of the Closing Date, as though made on

        date shall be true and correct as of such specific date), and Parent
        shall have received certificates to such effect signed by the Chief
        Executive Officer or the Chief Financial Officer of the Company with
        respect to Company matters.

               (b) Performance of Obligations of the Company. The Company shall
        have performed in all material respects all of its respective
        obligations and covenants, taken as a whole, required to be performed by
        it under this Agreement prior to or as of the Closing Date, and Parent
        shall have received a certificate to such effect signed by the Chief
        Executive Officer or the Chief Financial Officer of the Company.

               (c) Consents. Parent and Sub shall have received duly executed
        copies of all material third-party consents and approvals contemplated
        by this Agreement or the Company Disclosure Letter to be obtained by the
        Company in form and substance reasonably satisfactory to Parent and Sub,
        except those consents the failure to so receive would not, individually
        or in the aggregate, have a Material Adverse Effect on the Company.

               (d) Tax Opinion. Parent and Sub shall have received the opinion,
        dated the Closing Date, of Wachtell, Lipton, Rosen & Katz, special
        counsel to Parent, based upon customary representations, to the effect
        that (i) the Merger will be treated for federal income tax purposes as a
        reorganization within the meaning of Section 368(a) of the Code, and
        that each of the Company, Sub and Parent will be a party to that
        reorganization within the meaning of Section 368(b) of the Code, and
        (ii) no taxable gain or loss will be recognized, for federal income tax
        purposes, by shareholders of the Company who exchange Company Common
        Stock for shares of Parent Common Stock pursuant to the Merger (except
        with respect to cash received in lieu of fractional shares).

        SECTION 6.3. CONDITIONS OF OBLIGATIONS OF THE COMPANY. The obligation of
the Company to effect the Merger is subject to the satisfaction of the following
conditions, unless waived in writing by the Company:

               (a) Representations and Warranties. The representations and
        warranties of Parent and Sub set forth in this Agreement shall be true

        as of the Closing Date, as though made on and as of the Closing Date
        (provided, that in the cases of clauses (i) and (ii), any such
        representation and warranty made as of a specific date shall be true and
        correct as of such specific date), and the Company shall have received
        certificates to such effect signed by a senior executive officer of
        Parent and of Sub to such effect with respect to Parent matters and Sub

        effect signed by a senior executive officer of Parent and of Sub with
        respect to Parent and Sub matters, respectively.

               (c) Consents. The Company shall have received duly executed

        or in the aggregate, have a Material Adverse Effect on Parent.

               (d) Tax Opinion. The Company shall have received the opinion,
        dated the Closing Date, of Shearman & Sterling, special counsel to the
        Company, based upon customary representations, to the effect that (i)

SECTION 7.1. TERMINATION. This Agreement may be terminated at any time prior to
the Effective Time of the Merger, whether before or after approval of the Merger
by the shareholders of the Company:

               (a) by mutual written consent duly authorized by the Boards of
        Directors of Parent and the Company based on the recommendation of the
        Special Committee;

                                      -31-
<PAGE>   38


               (b) by either Parent or the Company if the Merger shall not have
        been consummated by December 31, 1998 (provided, that the right to
        terminate this Agreement under this Section 7.1(b) shall not be
        available to any party whose action or failure to act has been the cause
        of or resulted in the failure of the Merger to occur on or before such
        date and such action or failure to act constitutes a breach of this
        Agreement);

               (c) by either Parent or the Company, if (i) a court of competent
        jurisdiction or other Governmental Entity shall have issued an order,
        decree or ruling or taken any other action, in any case having the
        effect of permanently restraining, enjoining or otherwise prohibiting
        the Merger, which order, decree or ruling is final and nonappealable or
        (ii) a governmental, regulatory or administrative agency or commission
        shall seek to enjoin the Merger and the terminating party reasonably
        believes that the time period required to resolve such governmental
        action and the related uncertainty is reasonably likely to have a
        Material Adverse Effect on either Parent or the Company;

               (d) by either Parent or the Company, if the required approvals of
        the shareholders of the Company contemplated by this Agreement shall not
        have been obtained by reason of the failure to obtain the required vote
        upon a vote taken at a Shareholders Meeting or at any adjournment
        thereof (provided, that the right to terminate this Agreement under this
        Section 7.1(d) shall not be available to any party where the failure to
        obtain shareholder approval of such party shall have been caused by the
        action or failure to act of such party in breach of this Agreement);

               (e) by Parent, if the Board of Directors of the Company acting on
        the recommendation of the Special Committee shall have withdrawn or
        modified its recommendation concerning the Merger in accordance with
        Section 5.4 hereof;

               (f) by the Company, upon a breach of any representation,
        warranty, covenant or agreement on the part of Parent set forth in this
        Agreement, or if any representation or warranty of Parent shall have
        become untrue, in either case such that the conditions set forth in
        Section 6.3(a) or Section 6.3(b) would not be satisfied as of the time
        of such breach or as of the time such representation or warranty shall
        have become untrue, provided, that if such inaccuracy in Parent's
        representations and warranties or breach by Parent is curable by Parent
        through the exercise of its reasonable efforts and for so long as Parent
        continues to exercise such reasonable efforts, the Company may not
        terminate this Agreement under this Section 7.1(f); or

               (g) by Parent, upon a breach of any representation, warranty,
        covenant or agreement on the part of the Company set forth in this
        Agreement, or if any representation or warranty of the Company shall
        have become untrue, in either case such that the conditions set forth in
        Section 6.2(a) or Section 6.2(b) would not be satisfied as of the time
        of such breach or as of the time such representation or warranty shall
        have become untrue, provided, that if such inaccuracy in the Company's
        representations and warranties or breach by the Company is curable by
        the Company through the exercise of its

                                      -32-

<PAGE>   39

        reasonable efforts and for so long as the Company continues to exercise
        such reasonable efforts, Parent may not terminate this Agreement under
        this Section 7.1(g).

        SECTION 7.2. EFFECT OF TERMINATION. In the event of the termination of
this Agreement as provided in Section 7.1, this Agreement shall be of no further
force or effect, except (a) as set forth in the last sentence of Section 5.1,
this Section 7.2, Section 7.3, and Article 8, each of which shall survive the
termination of this Agreement, and (b) nothing herein shall relieve any party
from liability for any breach of this Agreement.

        SECTION 7.3. FEES AND EXPENSES. All fees and expenses incurred in
connection with this Agreement and the Transactions shall be paid by the party
incurring such expenses, whether or not the Merger is consummated.

                                    ARTICLE 8

                               GENERAL PROVISIONS

SECTION 8.1 AMENDMENT. This Agreement (including the Exhibits and disclosure
letters hereto) may be amended prior to the Effective Time by Parent, Sub and
the Company, by action taken by the Board of Directors of Parent and the Board
of Directors of the Company (provided, that no amendment shall be approved by
the Board of Directors of the Company unless such amendment shall have been
recommended by the Special Committee and, if required by law, approved by the
disinterested directors of the Company), at any time before or after approval of
the Merger by the shareholders of the Company but, after any such approval, no
amendment shall be made which by law requires further approval by such
shareholders without such further approval. This Agreement may not be amended
except by an instrument in writing signed on behalf of each of the parties.

        SECTION 8.2. EXTENSION; WAIVER. At any time prior to the Effective Time
(whether before or after approval of the shareholders of the Company), Parent
and the Company may (a) extend the time for the performance of any of the
obligations or other acts of the other parties, (b) waive any inaccuracies in
the representations and warranties contained in this Agreement or in any
document delivered pursuant to this Agreement and (c) waive compliance with any
of the agreements or conditions contained in this Agreement. Any extension or
waiver on behalf of the Company shall be taken only upon the recommendation of
the Special Committee (and, if required by law, by the disinterested directors
of the Company). Any agreement on the part of a party to any such extension or
waiver shall be valid only if set forth in an instrument in writing signed on
behalf of such party.

        SECTION 8.3. NONSURVIVAL OF REPRESENTATIONS, WARRANTIES AND AGREEMENTS.
All representations, warranties and agreements in this Agreement or in any
instrument or certificate delivered pursuant to this Agreement shall be deemed
to be conditions to the Merger and shall not survive the Merger, except for the
agreements contained in Sections 2.2 (exchange of Certificates), 2.3 (Company
Options), 2.4 (further assurances), 5.11 (indemnification), 5.13 (employee
agreements) and 5.14 (reorganization), each of which shall survive the Merger.

<PAGE>   40


        SECTION 8.4. ENTIRE AGREEMENT. This Agreement (including the Exhibits
and disclosure letters hereto) and the Confidentiality Agreement contain the
entire agreement among all of the parties with respect to the subject matter
hereof and supersede all prior arrangements and understandings, both written and
oral, with respect thereto, but shall not supersede any agreements among any
group of the parties hereto entered into on or after the date hereof. In this
regard, the breach of the Cooperation Agreement in and of itself shall not be
deemed to be a breach of this Agreement.

        SECTION 8.5. SEVERABILITY. It is the desire and intent of the parties
that the provisions of this Agreement be enforced to the fullest extent
permissible under the law and public policies applied in each jurisdiction in
which enforcement is sought. Accordingly, in the event that any provision of
this Agreement would be held in any jurisdiction to be invalid, prohibited or
unenforceable for any reason, such provision, as to such jurisdiction, shall be
ineffective, without invalidating the remaining provisions of this Agreement or
affecting the validity or enforceability of such provision in any other
jurisdiction. Notwithstanding the foregoing, if such provision could be more
narrowly drawn so as not to be invalid, prohibited or unenforceable in such
jurisdiction, it shall, as to such jurisdiction, be so narrowly drawn, without
invalidating the remaining provisions of this Agreement or affecting the
validity or enforceability of such provision in any other jurisdiction.

        SECTION 8.6. NOTICES. All notices and other communications pursuant to
this Agreement shall be in writing and shall be deemed to be sufficient if
contained in a written instrument and shall be deemed given if delivered

prepaid, to the parties at the following addresses (or at such other address for

                                    EXHIBIT A
                        FORM OF COMPANY AFFILIATE LETTER

USA Networks, Inc.
152 West 57th Street
New York, NY 10019

Gentlemen:

               I have been advised that as of the date of this letter I may be
deemed to be an "affiliate" of Ticketmaster Group, Inc., an Illinois corporation
(the "Company"), as the term "affiliate" is defined for purposes of paragraphs
(c) and (d) of Rule 145 of the rules and regulations (the "Rules and
Regulations") of the Securities and Exchange Commission (the "Commission") under
the Securities Act of 1933, as amended (the "Act"). Pursuant to the terms of the
Agreement and Plan of Merger dated as of March 20, 1998 (the "Agreement"), by
and among USA Networks, Inc., a Delaware corporation ("Parent"), Brick
Acquisition Corp., an Illinois corporation ("Sub"), and the Company, Sub will be
merged with and into the Company (the "Merger").

               As a result of the Merger, I may receive shares of common stock,
par value $.01 per share, of Parent ("Parent Securities"). I would receive such
shares in exchange for shares (or options for shares) owned by me of common
stock, no par value per share, of the Company.

               I represent, warrant and covenant to Parent that in the event I
receive any Parent Securities as a result of the Merger:

               1. I shall not make any sale, transfer, assignment or other
        disposition of the Parent Securities in violation of the Act or the
        Rules and Regulations.

               2. I have carefully read this letter and the Agreement and
        discussed the requirements of such documents and other applicable
        limitations upon my ability to sell, transfer, assign or otherwise
        dispose of Parent Securities, to the extent I felt necessary, with my
        counsel or counsel for the Company.

               3. I have been advised that the issuance of Parent Securities to
        me pursuant to the Merger has been registered with the Commission under
        the Act on a Registration Statement on Form S-4. However, I have also
        been advised that, because at the time the Merger is submitted for a
        vote of the shareholders of the Company, (a) I may be deemed to be an
        affiliate of the Company and (b) the distribution by me of the Parent
        Securities has not been registered under the Act, I may not sell,
        transfer, assign or otherwise dispose of Parent Securities issued to me
        in the Merger unless (i) such sale, transfer, assignment or other
        disposition is made in conformity with the volume and other limitations
        of Rule 145 promulgated by the Commission under the Act, (ii) such sale,
        transfer, assignment or other disposition has been registered under the
        Act or (iii) in the opinion of counsel reasonably acceptable to Parent,
        such sale, transfer, assignment or other disposition is otherwise exempt
        from registration under the Act.


                                      A-1

<PAGE>   45

               4. I understand that Parent is under no obligation to register
        the sale, transfer, assignment or other disposition of Parent Securities
        by me or on my behalf under the Act or to take any other action
        necessary in order to make compliance with an exemption from such
        registration available solely as a result of the Merger.

               5. I also understand that there will be placed on the
        certificates for the Parent Securities issued to me or any substitutions
        therefor, a legend stating in substance:

               THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A
               TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES
               ACT OF 1933, AS AMENDED, APPLIED. THE SHARES REPRESENTED BY THIS
               CERTIFICATE MAY ONLY BE TRANSFERRED IN ACCORDANCE WITH THE TERMS
               OF AN AGREEMENT DATED [           ] BETWEEN THE REGISTERED HOLDER
               HEREOF AND USA NETWORKS, INC., A COPY OF WHICH AGREEMENT IS ON
               FILE AT THE PRINCIPAL OFFICES OF USA NETWORKS, INC.

               6. I also understand that unless a sale or transfer is made in
        conformity with the provisions of Rule 145, or pursuant to a
        registration statement, Parent reserves the right to put the following
        legend on certificates issued to any transferee:

               THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
               REGISTERED UNDER THE SECURITIES ACT OF 1933 AND WERE ACQUIRED
               FROM A PERSON WHO RECEIVED SUCH SHARES IN A TRANSACTION TO WHICH
               RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF 1933, AS
               AMENDED, APPLIED. THE SHARES HAVE BEEN ACQUIRED BY THE HOLDER NOT
               WITH A VIEW TO, OR FOR RESALE IN CONNECTION WITH, ANY
               DISTRIBUTION THEREOF WITHIN THE MEANING OF THE SECURITIES ACT OF
               1933, AS AMENDED, AND MAY NOT BE SOLD, PLEDGED OR OTHERWISE
               TRANSFERRED EXCEPT IN ACCORDANCE WITH AN EXEMPTION FROM THE
               REGISTRATION REQUIREMENTS OF THE SECURITIES ACT OF 1933, AS
               AMENDED.

               It is understood and agreed that the legends set forth in
paragraphs 5 and 6 above shall be removed by delivery of substitute certificates
without such legend if the undersigned shall have delivered to Parent a copy of
a letter from the staff of the Commission, or an opinion of counsel reasonably
satisfactory to Parent in form and substance reasonably satisfactory to Parent,
to the effect that such legend is not required for purposes of the Act.

               Execution of this letter should not be considered an admission on
my part that I am an "affiliate" of the Company as described in the first
paragraph of this letter, or as a waiver of any rights I may have to object to
any claim that I am such an affiliate on or after the date of this letter.

                                            Very truly yours,


                                             -----------------------------------
