                        Pursuant to Section 13(d) of the

                          HOME SHOPPING NETWORK, INC.


          This Report on Schedule 13D relates to the common stock, par value
$.01 per share (the "Common Stock"), of Home Shopping Network, Inc., a Delaware
corporation (the "Company"). The Report on Schedule 13D originally filed by
Tele-Communications, Inc., a Delaware corporation ("TCI" or the "Reporting
Person"), on August 12, 1994, as amended and supplemented by the amendments
thereto previously filed with the Commission (collectively, the "TCI Schedule
13D"), is hereby amended and supplemented to include the information contained
herein, and this Report constitutes Amendment No. 4 to the TCI Schedule 13D.

          The summary descriptions contained in this Report of certain
agreements and documents are qualified in their entirety by reference to the
complete texts of such agreements and documents, filed as Exhibits hereto and
incorporated herein by reference.

ITEM 4.   PURPOSE OF TRANSACTION
          ----------------------

          Item 4 of the TCI Schedule 13D is hereby amended and supplemented by
adding the following information thereto:

          As previously reported, in light of the limitations relating to
increases in TCI's percentage equity ownership of Silver King contained in the
FCC June Order, Diller and TCI had begun discussions with respect to a
restructuring of the proposed transactions contemplated by the Merger Agreement
and the Exchange Agreement or a possible alternative transaction relating to the
Company.  In this regard, Diller and TCI considered a transaction which would
result in a merger of a subsidiary of Silver King into the Company (the "HSN
Merger") pursuant to which a portion of TCI's

                               Page 2 of 8 pages
<PAGE>
 
consideration in the HSN Merger would consist of a contingent right to acquire
Silver King shares and a portion of its interest in the Company would become an
interest in the surviving corporation in the HSN Merger. Such contingent right
and such interest in the surviving corporation would each be exchangeable into
Silver King shares, in each case, when and as permitted under applicable FCC
regulations, including the FCC June Order. On August 25, 1996, the Boards of
Directors of Silver King and the Company (based, in the case of the Company,
upon the recommendation of a special committee of independent members of the
Board of Directors of the Company) approved a merger transaction and related
transactions pursuant to which a wholly owned subsidiary of Silver King ("Sub")
would be merged with and into the Company, with the result that the Company
would be the surviving corporation and become an 80.1% owned subsidiary of
Silver King following the HSN Merger (with TCI owning the remaining 19.9%
interest in the surviving corporation). In connection with the HSN Merger,
substantially all of TCI's shares of Class B Stock of the Company would be
converted into Silver King Class B Common Stock, which would then be contributed
to an entity ("BDTV II") in which Diller owns all of the voting equity interests
and TCI owns a non-voting equity interest (which non-voting interest constitutes
substantially all the equity of BDTV II).

          If the HSN Merger is consummated, the Company would become a
consolidated subsidiary of Silver King.  The HSN Merger would cause the Common
Stock to be eligible for termination of registration under the Exchange Act and
to be delisted from the New York Stock Exchange.  TCI would no longer have a
controlling interest in the Company.  Because substantially all of the shares of
Silver King Class B Common Stock receivable by TCI in the HSN Merger will be
contributed to BDTV II, an entity which (other than with respect to certain
fundamental corporate actions) is controlled by Diller, TCI will not initially
have a controlling interest in Silver King.

          In connection with the execution of the HSN Merger Agreement (as
defined below), Silver King, Liberty and certain of Liberty's subsidiaries
entered into a voting agreement, dated August 25, 1996 (the "Voting Agreement"),
pursuant to which such Liberty entities agreed to vote the TCI HSN Shares in
favor of the HSN Merger and to vote the TCI HSN Shares against any action or
agreement that would impede, delay or discourage the HSN Merger.  In addition,
pursuant to such Voting Agreement, such Liberty entities agreed not to sell,
transfer or otherwise dispose of the TCI HSN Shares except pursuant to the HSN
Merger or following a termination of the HSN Merger Agreement.

          TCI has not made any determination as to its plans or proposals with
respect to the securities of the Company in the event that the HSN Merger is not
consummated.  In reaching any decision as to its course of action (as well as to
the specific elements thereof), TCI expects that it would take into
consideration a variety of factors, including but not limited to, the Company's
business and prospects, other developments concerning the Company and the cable
television and entertainment programming industries generally, other business
opportunities available to TCI and other developments with respect to the
business of TCI, general economic conditions and money and stock market
conditions, including the market price of the Common Stock.  TCI specifically
reserves the right to change its intention with respect to any of the foregoing
matters in the event the HSN Merger is not consummated, and to take any other
available course of action, which could involve one or more of the types of
transactions or have one or more of the results described in Item 4 of Schedule
13D.

ITEM 5.   INTEREST IN SECURITIES OF THE ISSUER.
          -------------------------------------

          If the HSN Merger is consummated, 19,260,859 shares of Class B Stock
would be converted into 7,756,564 shares of Silver King Class B Common Stock and
the contingent right to acquire 2,644,299 shares of Silver King Class B Common
Stock.  739,141 shares of Class B would be exchanged for an equal number of
shares of the surviving corporation and 17,566,702 shares of Common Stock would
be exchanged for a like number of shares of common stock of the surviving
corporation.  Such shares of the surviving corporation would be exchangeable for
shares of Silver King stock at the same ratio specified in the HSN Merger
Agreement.  As a result, in the HSN Merger TCI would dispose of its entire 
equity interest in the Company.

ITEM 6.   CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIP WITH RESPECT
          --------------------------------------------------------------------
          TO THE SECURITIES OF THE ISSUER
          -------------------------------

          Item 6 of the TCI Schedule 13D is hereby amended and supplemented by
adding the following information thereto:

          The information set forth in Item 4 above is hereby incorporated by
reference herein.

          Pursuant to the terms of the Agreement and Plan of Exchange and Merger
(the "HSN Merger Agreement"), dated as of August 25, 1996, by and among the
Company, Silver King, Sub and Liberty HSN, Inc. (the subsidiary of TCI which
holds the TCI HSN Shares), holders of Common Stock would receive 0.45 of a share
of Silver King Common Stock for each share of Common Stock. The Class B Stock,
which is solely held by TCI, would be converted into 0.54 of a share of Silver
King Class B Common Stock in the HSN Merger. In order to comply with the FCC
June Order (which limited TCI's percentage equity interest in Silver King to
21.37% unless prior FCC approval was obtained), TCI agreed in the HSN Merger
Agreement (i) to exchange 17,566,702 shares of Common Stock and 739,141 shares
of Class B Stock with Sub prior to the HSN Merger, which shares would become
shares of common stock and Class B common stock of the surviving corporation in
the HSN Merger and, upon TCI being entitled to own such shares in accordance
with applicable FCC regulations, would be exchanged (pursuant to an exchange
agreement to be entered into by Silver King and Liberty HSN, Inc. prior to the
HSN Merger) into Silver King Common Stock and Silver King Class B Common Stock
at the same rate such Company shares would have been converted into Silver King
shares in the HSN Merger, and (ii) approximately 2.6 million of the
approximately 10.4 million shares of Silver King Class B Common Stock to which
TCI would be entitled to receive in the HSN Merger would become "Contingent
Shares" to be issued to TCI at such time as TCI would be entitled, under
applicable FCC regulations, to own such shares. In the event that any Contingent
Shares remained to be issued after the third anniversary of the HSN Merger, such
shares would also be issuable to TCI at such time as it received FCC approval
(including an FCC approval allowing TCI to own such shares for a limited period
of time in order to effect the disposition of such shares) on or before the
fifth anniversary of the HSN Merger. If such Contingent Shares are issued to TCI
after the third anniversary of the HSN Merger and sold by it, Silver King will
be obligated to issue to TCI an additional number of shares to compensate it for
certain taxes payable as a result of such sale.

          The consummation of the HSN Merger is subject to a number of
conditions, including, but not limited to, approval by the stockholders of 
the Company (which will include, in addition to the stockholder approval
required under Delaware law, approval by the holders of a majority of the Common
Stock voting at the meeting at which the HSN Merger is to be considered,
excluding Liberty)


                               Page 4 of 8 pages
<PAGE>

and approval by the stockholders of Silver King of the issuance of the shares of
Silver King Common Stock and Silver King Class B Common Stock in the HSN Merger
(including the future issuances to TCI of the Contingent Shares and the shares
issuable to TCI upon the exchange of its shares of the surviving corporation),
and the receipt of certain regulatory consents and approvals, including approval
by the FCC. If the HSN Merger is not consummated by September 1, 1997, each of
the Company, Silver King and TCI have the right to terminate the transaction.
There can be no assurance that these conditions will be met.

          In connection with the execution of the HSN Merger Agreement, Liberty
and Diller also entered into a letter agreement, dated as of August 25, 1996
(the "Amendment Agreement"), which amended the SK Stockholders Agreement and by
its terms superseded the amendment to the SK Stockholders Agreement entered into
by Diller and Liberty on November 27, 1995.  The Amendment Agreement does not
effect a material change in the relationship between Diller and Liberty with
respect to the equity securities of Silver King as described in Amendment No. 2
to the TCI Schedule 13D, except that Diller no longer has an obligation to use
reasonable best efforts to cause a designee of TCI to serve on the Board of
Directors of the Company.  As described in Amendment No. 2, Diller has the right
to exercise voting authority over all equity securities of Silver King owned by
TCI, subject to certain restrictions.  The securities of Silver King acquired by
TCI in the HSN Merger, including shares acquired in connection with the
contingent interest and upon exchange of securities of the surviving corporation
in the HSN Merger, will be subject to the SK Stockholders Agreement.

          The parties to the Merger Agreement, dated November 27, 1995, and the
Exchange Agreement, dated November 27, 1995, entered into a Termination
Agreement, dated as of August 25, 1996 which terminated the Merger Agreement and
the Exchange Agreement upon execution and delivery of the HSN Merger Agreement.

          The foregoing summary descriptions of the HSN Merger Agreement, the
Amendment Agreement, the Voting Agreement and the Termination Agreement are
qualified in their entirety by reference to the complete texts of such
agreements, filed as Exhibits hereto and incorporated herein by reference.

                       SILVER KING COMMUNICATIONS, INC.
                        AND HOME SHOPPING NETWORK, INC.
                          ANNOUNCE AGREEMENT TO MERGE


NEW YORK NY -- Silver King Communications, Inc. (NASDAQ: SKTV) and Home Shopping
Network, Inc. (NYSE: HSN) today entered into a definitive merger agreement,
pursuant to which Home Shopping Network (HSN) will become a subsidiary of Silver
King.  The merger marks the reunification of the two companies which split in
1992 and supersedes Silver King's previous agreement to purchase only Liberty
Media Corp.'s (NASDAQ: LBTYA) controlling interest in HSN.

Combined, Silver King and Home Shopping Network occupy a unique position with
cable, broadcast and electronic retailing programming interests.  In addition to
HSN's pioneering electronic retailing business and Silver King's television
broadcast group, the sixth largest in the nation (with interests in 21 full-
power stations), the new company's assets will include the Internet Shopping
Network (ISN), one of the largest electronic retailers on the Internet; Vela
Research, specializing in digital video encoder/decoder technology; and, pending
consummation of Silver King's merger agreement with Savoy Pictures
Entertainment, Inc. (NASDAQ: SPEI), SF Broadcasting, which owns and operates VHF
Fox affiliates in four major markets.

                                                                     page 2 of 5


Under the terms of the merger agreement, holders of HSN Common Stock will
receive 0.45 of a share of Silver King Common Stock for each share of HSN Common
Stock.  Each share of HSN Class B Stock, which has ten votes per share and is
held solely by Liberty Media Corp., will be converted into 0.54 of a share of
Silver King Class B Stock.  The consideration to be received by Liberty Media
represents a premium of 10.67 percent on its aggregate holdings of HSN Common
Stock and Class B Stock.  Consummation of the merger is subject to Silver King
and HSN shareholder approvals.  Approval from HSN shareholders will include the
majority decision of holders of HSN Common Stock voting at the meeting,
excluding Liberty Media Corp.  Approval from Silver King shareholders will
include the majority decision of holders of Silver King Common Stock.

"At no risk of overstatement, this is a complex transaction," stated Silver King
and HSN Chairman Barry Diller. "Not that it needs suggestion, but given the
interrelationships of HSN's and Silver King's businesses, its Chairman, and
Liberty Media's large shareholdings in both companies, I invite a detailed
evaluation of the proposed merger. I am confident that such scrutiny will
support the transaction's minimum criteria, i.e. that it is fair and balanced
and in the best interest of all shareholders. As to its more expansive
possibilities, I believe the combination will allow the companies the very best
way to pursue their very aggressive individual agendas with clarity and without
conflict."

                                                                     page 3 of 5


To represent the interests of Home Shopping Network's shareholders other than
Liberty Media and Barry Diller, HSN's Board of Directors formed a Special
Committee of Independent Directors, which in turn retained independent counsel
and financial advisors to negotiate the terms of the merger.  The Committee
approved the transaction, which was subsequently approved by HSN's Board of
Directors based on the Committee's recommendation.

"This merger enhances the value of both Silver King Communications and Home
Shopping Network," stated HSN Board member and Chief Executive Officer James
Held.  "HSN is directly on target with a realistic but aggressive revenue growth
plan while Silver King's business plan has significant upside potential.
Combined, the company can nurture its subsidiaries more efficiently and has the
proper base to support entirely new ventures that capitalize on its collective
assets."

As Liberty Media Corp. may not at this time own more than a 21.37 percent equity
interest in Silver King without further Federal Communications Commission (FCC)
approval, initially Liberty Media will not exchange 18.3 million HSN shares
(17.57 million shares of Common Stock and 0.74 million shares of Class B Stock)
for Silver King securities.  Instead, Liberty Media will retain a 19.9% minority
interests in HSN, which, under the terms of the merger, must be exchanged, in a
tax-free transaction, for additional Silver King shares as soon as possible
consistent with applicable FCC guidelines.

Additionally, approximately 2.6 million contingent shares of Silver King Class B
Stock due Liberty Media for shares of HSN Class B Stock acquired in the merger
will not be issued until such time as Liberty Media is legally permitted to own
them.  Silver King management believes it highly unlikely that this exchange
will not be completed within three years of the consummation of the merger
agreement.  However, if at the end of three years any of the 2.6 million Silver
King contingent shares have not been issued, Liberty Media would also have the
right during the next two years to dispose of such shares, plus additional
shares from Silver King to pay any related taxes, provided Liberty Media can
obtain FCC approval to do so.

Upon closing of the merger (prior to any conversion of Liberty Media's 19.9
percent retained interest), Home Shopping Network will become an 80.1 percent
subsidiary of Silver King Communications.  Original Silver King shareholders
(other than Liberty Media) will own approximately 7.4 million Silver King
shares, former HSN Common Stock shareholders (other than Liberty Media) will own
approximately 24.5 million Silver King shares and Liberty Media Corp. will own
approximately 9.8 million Silver King shares (including approximately 2.1
million already owned).  Additionally, shareholders of Savoy Pictures
Entertainment will own approximately 4.2 million Silver King shares upon
completion of that transaction.  Silver King shares received by Liberty Media
under the merger agreement will be subject to the terms of an existing
stockholders agreement between Liberty Media and Barry Diller, pursuant to which

                   AGREEMENT AND PLAN OF EXCHANGE AND MERGER


          THIS AGREEMENT AND PLAN OF EXCHANGE AND MERGER (this "Agreement") is
dated as of August 25, 1996, by and among SILVER KING COMMUNICATIONS, INC., a
Delaware corporation ("Parent"), HOUSE ACQUISITION CORP., a Delaware corporation
and a wholly owned subsidiary of Parent ("Sub"), HOME SHOPPING NETWORK, INC., a
Delaware corporation (the "Company"), and LIBERTY HSN, INC., a Colorado
corporation ("Liberty HSN").

                                   RECITALS:

          A.  The Boards of Directors of Parent, Sub and the Company and the
Special Committee of the Board of Directors of 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 General Corporation Law of the State of Delaware (the "Delaware
Statute"), and each deems the Merger advisable and in the best interests of each
corporation.

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

          C.  Concurrently with the execution of this Agreement and as an
inducement to Parent to enter into this Agreement, each of the persons listed on
Annex A has entered into a voting agreement (the "Company Voting Agreement")
pursuant to which such person has agreed, among other things, to vote its shares
of Company Stock (as defined in Section 2.1(d)) in favor of this Agreement, the
Merger and the other transactions contemplated by this Agreement.

          D.  Concurrently with the execution of this Agreement and as an
inducement to the Company to enter into this Agreement, each of the persons
listed on Annex B has entered into a voting agreement (the "Parent Voting
Agreement") pursuant to which such person has agreed, among other things, to
vote its shares, or to cause BDTV INC., a Delaware corporation and the holder of
Parent Stock ("BDTV"), to vote shares that are beneficially or of record owned
by such person and are held by BDTV, of Parent Stock (as defined in Section
2.1(d)), in favor of the issuance of Parent Stock in connection with the Merger
and any other matter which requires its vote in connection with the transactions
contemplated by this Agreement.

          E.  For federal income tax purposes, it is intended that the Merger
and the transactions contemplated thereby (including the issuance of Parent
Stock pursuant to the Contingent Right (as defined in Section 2.1(d))) and by
the Exchange Agreement (as defined in Section 3.4) qualify as a reorganization
under the provisions of Section 368(a) of the United States Internal Revenue
Code of 1986, as amended (the "Code").

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

filing of the Certificate of Merger with the Secretary of State of the State of
Delaware (the "Effective Time").

          SECTION 1.4.  CLOSING.  Unless this Agreement shall have been
                        -------                                        
terminated pursuant to Section 8.1, the closing of the Exchange and the Merger
(the "Closing") will take place at 10:00 a.m. on a date (the "Closing Date") to

certificate referred to therein), and 7.3(c), and shall be on the same day as

conditions set forth in Article 7 have been satisfied or waived at or prior to
the Closing), unless another date is agreed to in writing by the parties.  The
Closing shall take place at the offices of Wachtell, Lipton, Rosen & Katz, 51
West 52nd Street, New York, New York 10019, unless another place is agreed to in
writing by the parties.  As used in this Agreement, "Business Day" shall mean
any day, other than a Saturday, Sunday or legal holiday on which banks are
permitted to close in the City and State of New York and the State of Delaware.

          SECTION 1.5.  EFFECTS OF THE MERGER.  At the Effective Time:  (a) the
                        ---------------------

Company shall be the certificate of incorporation of the Surviving Corporation

               CONSTITUENT CORPORATIONS; EXCHANGE OF CERTIFICATES

          SECTION 2.1.  EFFECT 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, $.00001 par value per share, of Sub shall be converted into 1
     validly issued, fully paid and nonassessable share of common stock, $.01
     par value per share, of the Surviving Corporation ("Surviving Corporation
     Common Stock"), and each issued and outstanding share of the Class B common
     stock, $.00001 par value per share, of Sub shall be converted into 1
     validly issued, fully paid and nonassessable share of Class B common stock,
     $.01 par value per share, of the Surviving Corporation ("Surviving
     Corporation Class B 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 and shares
     of Surviving Corporation Class B Common Stock.

          (b)  Cancellation of Certain Shares of Company Common Stock and
               ----------------------------------------------------------
     Company Class B Common Stock.  Each share of Company Common Stock and
     ----------------------------                                         
     Company Class B 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 be cancelled and retired and
     shall cease to exist, and no capital stock of Parent or other consideration
     shall be delivered in exchange therefor.

          (c)  Exchange Ratio for Company Common Stock.  Each share of common
               ---------------------------------------                       
     stock, $.01 par value per share, of the Company ("Company Common Stock"),
     issued and outstanding immediately prior to the Effective Time (other than
     shares of Company Common Stock to be cancelled pursuant to Section 2.1(b)),
     shall be converted into the right to receive 0.45 of a fully paid and
     nonassessable share of common stock, $.01 par value per share, of Parent
     ("Parent Common Stock") (the 

                                      -3-
<PAGE>
 
     "Common Stock 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)  Exchange Ratio for Company Class B Common Stock.  Each share of
               -----------------------------------------------                
     Class B common stock, $.01 par value per share, of the Company ("Company
     Class B Common Stock" and, together with the Company Common Stock, "Company
     Stock"), issued and outstanding immediately prior to the Effective Time
     (other than shares of Company Common Stock to be cancelled pursuant to
     Section 2.1(b)), shall be converted into the right to receive at the
     effective time (i) 0.54 of a fully paid and nonassessable share of Class B
     common stock, $.01 par value per share, of Parent ("Parent Class B Common
     Stock" and, together with the Parent Common Stock, "Parent Stock") (the
     "Class B Common Stock Exchange Ratio"), and (ii) a pro rata interest in the
     contingent right to receive additional shares of Parent Class B Common
     Stock pursuant to the terms set forth in Exhibit A hereto (the "Contingent
     Right").  At the Effective Time, all such shares of Company Class B 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 Class B Common
     Stock to be issued in consideration therefor (including pursuant to the
     Contingent Right) upon the due surrender of such certificate to Parent, and
     the holder of Company Class B Common Stock shall receive a certificate
     representing the number of shares of Parent Common Stock described in
     clause (i) hereof, without interest.  No fractional shares of Parent Class
     B Common Stock shall be issued, and, in lieu thereof, a cash payment shall
     be made without any interest thereon, based on the closing market price as
     of the Business Day preceding such exercise on the principal national
     securities exchange or interdealer system on which the Parent Common Stock
     is then listed or quoted multiplied by the fractional interest.

          (e)  Adjustment of Common Stock Exchange Ratio and Class B Common
               ------------------------------------------------------------
     Stock Exchange Ratio.  If, between the date of this Agreement and the
     --------------------                                                 
     Effective Time, the outstanding shares of Parent Common Stock or Parent
     Class B 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 combination, exchange of
     shares, readjustment or otherwise, then the Common Stock Exchange Ratio or
     the Class B Common Stock Exchange Ratio (including the Contingent Right),
     as the case may be, shall be correspondingly adjusted.

          (f)  Adjustment of Contingent Right and Shares under Exchange
               --------------------------------------------------------
     Agreement.  To the extent that, immediately prior to the Effective Time,
     ---------                                                               
     Liberty Media Corporation, a Delaware corporation ("Liberty"), Tele-
     Communications, Inc., a Delaware corporation ("TCI"), and the controlled
     affiliates of Liberty and TCI (collectively, including Liberty HSN, the
     "Liberty Group") are legally permitted under applicable law (including
     federal communications statutes and the rules, regulations, orders, 

                                      -4-
<PAGE>
 
     decrees and policies of the Federal Communications Commission (the "FCC"),
     and any interpretations or waivers thereof or modifications thereto (such
     provisions collectively, "FCC Regulations")), to own, directly or
     indirectly, and without limitation or restriction relating to the
     continuation of such ownership following issuance, or the imposition of any
     additional restrictions on the business or assets of the Liberty Group or
     Parent, in excess of 9,818,194 shares of Parent Stock (the number the
     Liberty Group would be permitted to own as of the date hereof), as if that
     certain merger referred to in Section 7.1(h) and the Merger had been
     consummated as of the date hereof, the following adjustments shall be made:
     (i) the Contingent Right shall first be reduced by such excess (and the
     total number of shares of Parent Class B Common Stock to be issued to the
     Liberty Group at the Effective Time shall be increased pursuant to Section
     2.1(d)), until such time as the number of shares of Parent Class B Common
     Stock to be issued pursuant to the Contingent Right equals zero, (ii)
     thereafter, the number of shares of Company Class B Common Stock to be
     exchanged for shares of Sub Class B Common Stock shall be reduced (and the
     number of shares of Parent Class B Common Stock to be issued to the Liberty
     Group at the Effective Time shall be increased based on the Class B Common
     Stock Exchange Ratio), and (iii) thereafter, the number of shares of
     Company Common Stock to be exchanged for shares of Sub Common Stock shall
     be reduced (and the number of shares of Parent Common Stock to be issued to
     the Liberty Group at the Effective Time shall be increased, based on the
     Common Stock Exchange Ratio).

          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 Stock, for exchange in accordance with this Article 2, certificates
representing the shares of Parent Stock (such shares of Parent Stock, together
with any dividends or distributions with respect thereto, are referred to as 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), but shall not include shares of Parent Stock to be issued
pursuant to the Exchange Agreement or the Contingent Right.  The procedures
provided in this Section 2.2 shall not apply to such shares of Parent Stock.

          (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 or Parent Class B Common Stock pursuant to Section
2.1(c) of this Agreement, (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 Stock and any
cash in lieu of fractional shares of Parent Stock or Parent 

                                      -5-
<PAGE>
 
Class B 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 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 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 Stock and any cash in lieu of fractional shares of Parent Stock
may be issued and paid to a transferee if the Certificate representing such
Company 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 or Parent Class B
Common Stock and cash in lieu of any fractional shares of Parent Stock as
contemplated by this Article 2 and the Delaware 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 or Parent Class B 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 or Parent Class B Common Stock issued in exchange therefor,
without interest, (i) at the time of such surrender, the amount of any cash
payable in lieu of a fractional share of Parent 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 or Parent Class B Common Stock with a
record date after the Effective Time theretofore paid with respect to such whole
shares of Parent Stock, and (ii) at the appropriate payment date, the amount of
dividends or other distributions on Parent Common Stock or Parent Class B 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 Stock.

          (d)  No Further Ownership Rights in Company Common Stock.  All shares
               ---------------------------------------------------             
of Parent Common Stock or Parent Class B Common Stock issued upon the surrender
for exchange of shares of Company Common Stock or Company Class B 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 or
Company Class B 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 or Company Class B 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 

                                      -6-
<PAGE>
 
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 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 stockholder 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 of Company
     Common Stock pursuant to Section 2.2(b) (such excess being herein called
     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).
     A fractional share of Parent Class B Common Stock shall be deemed to have
     the same value as the same fractional share of Parent Common Stock. To the
     extent that a fractional share of Parent Class B Common Stock would
     otherwise be issued in the Merger, the Company shall pay directly to such
     holder of Company Class B Common Stock the amount of cash, if any, in lieu
     of any fractional share interests and subject to clause (v) 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 stockholders of the
Company for twelve months after the Effective Time shall be delivered to Parent,
upon demand, and any former stockholders 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.

          (g)  No Liability.  Neither the Exchange Agent, Parent, Sub nor the
               ------------                                                  
Company shall be liable to any holder of shares of Company Stock or Parent
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 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
                        -------------

Plan for Employees, the 1996 Stock Option Plan for Outside Directors, the 1986
Stock Option Plan for Employees and the 1986 Stock Option Plan for Directors
(collectively, the "Company Option Plans"), 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 Company Option Plans and the agreements pursuant
to which such Company Options were issued as in effect immediately prior to the
Effective Time, which plans and agreements shall be assumed by Parent, except
that (in accordance with the applicable provisions of such plans) (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 Common Stock 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 

                                      -8-
<PAGE>
 
equal the exercise price per share of Company Common Stock in effect immediately
prior to the Effective Time divided by the Common Stock Exchange Ratio. Parent
shall (i) 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 and (ii) promptly after the Effective Time issue to each holder of
an outstanding Company Stock Option a document evidencing the assumption by
Parent of the Company's obligations with respect thereto under 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
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 duly organized, validly existing and in good standing
under the laws of the jurisdiction of its incorporation and has the requisite
corporate 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 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.  Other than wholly owned
subsidiaries and except as disclosed in the Company SEC Reports (as defined in
Section 3.7(a)) or the Company Disclosure Letter (as defined in Section 3.3),
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, joint venture or other
business, association or entity.

          SECTION 3.2.  CERTIFICATE OF INCORPORATION AND BYLAWS.  The Company
                        ---------------------------------------              
has previously furnished or made available to Parent and Liberty HSN a complete
and correct copy of its certificate of incorporation and bylaws as amended to

or equivalent organizational documents.

          SECTION 3.3.  CAPITALIZATION.  The authorized capital stock of the
                        --------------

shares of Company Class B Common Stock and 500,000 shares of preferred stock,
par value $.01 per share, of the Company (the "Company Preferred Stock").  At
the close of business on August 23, 1996, (a) 78,975,159 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

under the Company Option Plans, and (d) debentures issued pursuant to the
Indenture (as defined in Section 6.15) presently convertible into 8,333,333.33
shares of Company Common Stock were issued and outstanding.  As of the date
hereof, no shares of Company Preferred Stock were issued or outstanding.  No
change in such capitalization has occurred between June 30, 1996 and the date
hereof except (i) the issuance of shares of Company Common Stock pursuant to the
exercise of outstanding options, (ii) shares issued upon conversion of the
debentures issued pursuant to the Indenture, and (iii) as contemplated by this
Agreement.  Except as set forth in this Section 3.3 or as disclosed in the
disclosure letter delivered by the Company to Parent and Liberty HSN (the
"Company Disclosure Letter"), as of the date of this Agreement, there are no
options, warrants or other rights, agreements, arrangements 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
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 shares of capital stock of each of the Company's subsidiaries are
duly authorized, validly issued, fully paid and nonassessable, and, except as
set forth in Section 3.3 of the Company Disclosure Letter, 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.  The Company has
                        ------------------------------------

Agreement and to perform its obligations hereunder and, subject to obtaining 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

or to consummate the Transactions so contemplated (other than, with respect to
the Merger, the approval and adoption of this Agreement by the stockholders of
the Company in accordance with the Delaware Statute and the Company's
certificate of incorporation and bylaws). 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 and Liberty HSN,
constitutes the legal and binding obligation of the Company, enforceable against
the Company in accordance with its terms, subject to (a) bankruptcy, insolvency,
reorganization, moratorium or other similar laws affecting or relating to
creditors rights generally and (b) 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 203 of the
Delaware Statute will not apply to Parent, Sub, Barry Diller or the Liberty
Group and their respective affiliates and associates with respect to or as a
result of this Agreement (including the issuance of Parent Stock pursuant to the
Contingent Right), the exchange agreement having the terms set forth on Exhibit
C hereto and otherwise in form and substance reasonably satisfactory to Parent,

          SECTION 3.6.  COMPLIANCE; PERMITS.

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

          (a)  The Company has delivered or made available to Parent prior to
the execution of this Agreement true and complete copies (or, in the case of
bonus or other incentive plans, summaries thereof) of all material pension,
retirement, profit-sharing, deferred compensation, stock option, employee stock
ownership, severance pay, vacation, bonus or other material incentive plans, all
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

Company or any Commonly Controlled Entity.

          (c)  No ERISA Plan which is a defined benefit pension plan has any
"unfunded current liability," as that term is defined in Section 302(d)(8)(A) of
ERISA, and the present fair market value of the assets of any such plan equals
or exceeds the plan's "benefit liabilities," as that term is defined in Section
4001(a)(16) of ERISA, when determined under actuarial factors that would apply
if the plan terminated in accordance with all applicable legal requirements.

          (d)  Neither the execution and delivery of this Agreement nor the
consummation of the Transactions will (i) result in any material payment
(including, without limitation, severance, unemployment compensation, golden
parachute or otherwise) becoming due to any director or any 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, except as provided under the Company Option Plans or related
agreement.

          SECTION 3.16.  TAX MATTERS.  Neither the Company nor any of its
                         -----------

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

existing and in good standing under the laws of the jurisdiction of its
incorporation and has the requisite corporate power and authority to own, lease

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,

<PAGE>
 
a Material Adverse Effect (as defined below). Each of Parent and its
subsidiaries is 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 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 taken as a whole. Other

retirement, profit-sharing, deferred compensation, stock option, employee stock
ownership, severance pay, vacation, bonus or other material incentive plans, all
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)

contributed to by Parent or any Commonly Controlled Entity of Parent for the
benefit of employees, retirees, dependents, spouses, directors, independent
contractors or other beneficiaries and under which employees, retirees,
dependents, spouses, directors, independent contractors or other beneficiaries

such plan equals or exceeds the plan's "benefit liabilities," as that term is
defined in Section 4001(a)(16) of ERISA, when determined under actuarial factors
that would apply if the plan terminated in accordance with all applicable legal
requirements.

compensation, golden parachute or otherwise) becoming due to any director or any
employee of Parent or any of its affiliates from Parent or any of its affiliates
under any Parent Benefit Plan or otherwise, (ii) materially increase any
benefits otherwise payable under any Parent Benefit Plan, or (iii) result in any

to respond to any comments of the SEC, to have the S-4 declared effective under

Securities Act or any other federal or Blue Sky Laws relating to the Merger and
the transactions contemplated by this Agreement, including, without limitation,

Filings"). The Company and Parent (and, in the case of the Schedule 13E-3, the
Liberty Group) will notify the other parties promptly of the receipt of any
comments from the SEC or its staff and of any request by the SEC or its staff or
any other government officials for amendments or supplements to the S-4, the
Schedule 13E-3, the Proxy Statement or any Other Filing or for additional
information and will supply the other with copies of all correspondence between
it or any of its representatives, on the one hand, and the SEC, or its staff or
any other government officials, on the other hand, with respect to the S- 4, the
Schedule 13E-3, the Proxy Statement, the Merger or any Other Filing. The Proxy
Statement, the Schedule 13E-3, the S-4 and the Other Filings shall comply in all
material respects with all applicable requirements of law. Whenever any event
occurs which is required to be set forth in an amendment or supplement to the

may be, shall promptly inform the other parties of such occurrence and cooperate
in filing with the SEC or its staff or any other government officials, and/or
mailing to stockholders of Parent and the Company, such amendment or supplement.
Subject to the fiduciary duties of the directors in accordance with applicable
law, the Proxy Statement shall include the recommendations of the Board of
Directors of Parent in favor of the issuance of Parent Common Stock and Parent
Class B Common Stock in connection with the Transactions and of the Board of
Directors of the Company in favor of approval of this Agreement and the
Transactions; provided, that the Board of Directors of the Company will not
              --------
recommend approval of this Agreement and the Transactions without the
recommendation of the Special Committee. The Company and Parent acknowledge and
agree that the Proxy Statement will also include information relating to the
matters disclosed in the Parent Disclosure Letter and any required vote of the
stockholders of Parent relating thereto, consistent with applicable requirements
of law. The Company and Parent each shall promptly provide the other (or its
counsel) copies of all filings made by it with any Governmental Entity in
connection with this Agreement and the transactions contemplated hereby. To the
extent information is required from Liberty HSN in connection with the Proxy
Statement and the S-4, Liberty HSN shall comply with the covenants of Parent and
the Company contained in this Section. In the event that the Merger is not
consummated on or prior to January 3, 1997, the covenants in this Section shall
apply to the filing by Parent, Sub, the Company and Liberty HSN of a pre-merger
notification report under the Hart-Scott-Rodino Antitrust Improvements Act of
1976, as amended (the "HSR Act"), and responding to any further informational
requests in connection with the receipt of termination or expiration of the
applicable waiting period under the HSR Act. Parent shall take all necessary
actions to cause the shares of Parent Common Stock issuable in connection with
the Company Option Plans to be registered under the Securities Act. Prior to the

assumption of the Company Option Plans as of the Effective Time shall be

     Special Committee;

          (b)  by either Parent, the Company or Liberty HSN if the Merger shall
     not have been consummated by September 1, 1997 (provided, that the right to
                                                     --------

     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
     stockholders of Parent or 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 Stockholders Meeting or at any adjournment thereof
     (provided, that the right to terminate this Agreement under this Section
     ---------                                                               
     8.1(d) shall not be available to any party where the failure to obtain
     stockholder 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

     such action or inaction shall not be due to a breach by Parent of the
     nature described in Section 6.2(a) or 6.2(b);

          (f)  by the Company, if the Board of Directors of Parent shall have
     withdrawn or modified the recommendation referred to in Section 4.14(c) and
     such action or inaction shall not be due to a breach by the Company of the
     nature described in Section 6.3(a) or 6.3(b);

          (g)  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 8.1(g); or

          (h)  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 reasonable efforts and for so long as the Company
     continues to exercise such reasonable efforts, Parent may not terminate
     this Agreement under this Section 8.1(h);

          (i)  by the Special Committee (or, if any member of the Special
     Committee is no longer serving in such capacity, any successor committee
     consisting of independent directors of the Company), if, at any time prior
     to the Effective Time, the arithmetic average of the mean of the closing
     bid and ask prices of Parent Common Stock on the NASD National Market (or
     other national market or exchange on which Parent Common Stock is then
     traded or quoted) for the 20 trading days immediately preceding such time
     is less than $22.125; or

          (j)  by Parent, if at any time prior to the Effective Time, the
     arithmetic average of the mean of the closing bid and ask prices of Parent
     Common Stock on the NASD National Market (or other national market or
     exchange on which Parent Common Stock is then traded or quoted) for the 20
     trading days immediately preceding such time is more than $36.875.

further force or effect, except (a) as set forth in the last sentence of Section
6.1, this Section 8.2, Section 8.3, and Article 9, 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 8.3.  FEES AND EXPENSES.  Except as set forth in this Section
                        -----------------                                      
8.3, all fees and expenses incurred in connection with this Agreement and the
transactions contemplated hereby shall be paid by the party incurring such
expenses, whether or not the Merger is consummated; provided, however, that
                                                    --------  -------

Exchange contemplated in Section 1.1 is consummated, but, for any reason
whatsoever, the Merger is not consummated immediately thereafter and on the same

by the Board of Directors of the Company unless such amendment shall have been
recommended by the Special Committee), at any time before or after approval of
the Merger by the stockholders of Parent and the Company but, after any such
approval, no amendment shall be made which by law requires further approval by
such stockholders without such further approval.  The foregoing notwithstanding,
this Agreement (including the Exhibits, Annexes and disclosure letters hereto)
may not be amended in any manner that affects the rights, obligations,
representations or warranties of Liberty HSN hereunder without the written

Time (whether before or after approval of the stockholders of Parent and the

Any agreement on the part of a party to any such extension or waiver shall be

                        ----------------------------------------------
AGREEMENTS.  All representations, warranties and agreements in this Agreement or

a member of the Liberty Group is a party to the August Agreement and the Silver

provided for hereunder) with respect to the subject matter hereof and supersede
all prior arrangements and understandings, both written and oral, with respect
thereto.

          SECTION 9.6.  SEVERABILITY.  It is the desire and intent of the

parties, including Liberty HSN, 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.

                    TERMS AND CONDITIONS REGARDING ISSUANCE
                    ---------------------------------------
               OF CONTINGENT PARENT SHARES TO LIBERTY HSN, INC.
               ------------------------------------------------


          The following provisions set forth the terms and conditions pursuant
to which, as part of the consideration to be received by Liberty HSN in the
Merger in respect of its shares of Company Class B Common Stock, Parent will
issue to Liberty HSN, from time to time upon the occurrence of certain events
(or as circumstances otherwise permit), additional shares of Parent Class B
Common Stock in satisfaction of Parent's obligation to issue to Liberty HSN (or
a wholly owned subsidiary thereof to which the Contingent Right has been
assigned) the shares of Parent Class B Common Stock which are not issued to it
at the time of the Merger (such shares, the "Contingent Parent Shares").
Capitalized terms not defined herein shall have the meanings ascribed to such
terms in the merger and exchange agreement to which this Exhibit A is attached
(the "Agreement").

Number of Contingent     
Parent Shares:         2,644,299 shares of Parent Class B Common Stock, less any
                       additional shares of Parent Class B Common Stock issued
                       at the Effective Time of the Merger, in accordance with
                       any adjustments required pursuant to Section 2.1(f) of
                       the Agreement, but subject to increase in connection with
                       the issuance of Extra Shares (as defined below).

Parent Obligation:     Upon the occurrence of, or in the event of the existence
                       of circumstances constituting, at any time subsequent to
                       the Effective Time and on or before the fifth anniversary
                       of the Effective Time, a Contingent Issuance Event (as
                       defined below), Parent shall issue to Liberty HSN a
                       number of Contingent Parent Shares (such additional
                       Contingent Parent Shares, the "Additional Shares") equal
                       to the Available Share Amount (as defined below)
                       determined at such time of, and after giving effect to,
                       the occurrence or existence of such Contingent Issuance
                       Event (and any share issuances resulting therefrom).
                       Parent shall issue any Additional Shares to Liberty HSN
                       simultaneously with or immediately following the
                       occurrence of a Contingent Issuance Event; subject,
                                                                  -------
                       however, to (i) the receipt of any and all
                       -------
                       consents, approvals or authorizations of any governmental
                       or regulatory entities, and the expiration or termination
                       of any waiting periods under the HSR Act required in
                       connection with the issuance of
<PAGE>
 
                       such Additional Shares, and (ii) such issuance not being
                       taxable to Liberty HSN; provided, however, that the
                                               --------  -------
                       condition to issuance of the Contingent Parent Shares set
                       forth in this clause (ii) shall be deemed satisfied to
                       the extent that (x) the taxability of such issuance to
                       Liberty HSN is a result of (1) any action or inaction by
                       Liberty HSN or a member of the Liberty Group (other than
                       due to an action or inaction specifically contemplated or
                       required by the Agreement, the Exchange Agreement, the
                       Term Sheet or the August Agreement (as defined in the
                       Term Sheet)) or (2) the nature of the Contingent Right
                       under laws and regulations in effect at the Effective
                       Time, or (y) the taxes applicable to such issuance would
                       have accrued or been payable by Liberty HSN had all of
                       the Contingent Parent Shares been issued to Liberty HSN
                       in the Merger at the Effective Time. Each of Parent and
                       Liberty HSN shall use their reasonable best efforts to
                       obtain any such required consent or approval, and to file
                       and cause the expiration or termination of any waiting
                       period required in accordance with the HSR Act, in each
                       case as promptly as practicable. At or after the
                       Effective Time, Liberty HSN shall have the right to
                       assign the Contingent Right, in whole or in part, to one
                       or more wholly owned subsidiaries of Liberty HSN; and
                       following such assignment the term "Liberty HSN" shall
                       for purposes of the Contingent Right be deemed to refer
                       to such assignee.

Contingent Issuance   
Event:                 The term "Contingent Issuance Event" shall mean any
                       event, including without limitation, any transaction,
                       stock issuance, change in law, rule, or regulation,
                       order, decree or policy and/or the existence or change in
                       any other circumstance(s), which results in Liberty HSN
                       being permitted under applicable FCC Regulations to own
                       (without limitation or restriction relating to the
                       continuation of such ownership following issuance, or the
                       imposition of any restriction or limitation of the type
                       referred to in clause (i) of the first sentence of the
                       last paragraph opposite the caption "Parent Covenants" or
                       any requirement to dispose or divest of any Parent
                       Securities (including any interest in BDTV, BDTV II or
                       any BDTV Entity (as defined in the Term Sheet)) or other
                       assets or businesses in connection with such Contingent
                       Issuance Event (any of the foregoing restrictions or
                       limitations, a "Restrictive Condition")) directly or
                       indirectly, a greater number of equity securities of

                       exchangeable for or convertible into equity securities of

                       Amount (as defined below) as of the date of the
                       occurrence or first existence of such Contingent Issuance
                       Event; provided, however, that a sale or other
                              --------  -------
                       disposition by the Liberty Group of Parent Securities or
                       Exchange Securities (as defined in Exhibit C to the
                       Agreement) shall not constitute or result in the
                       occurrence of a Contingent Issuance Event and such
                       securities shall not be considered in determining the
                       number of Parent Securities issuable in connection with a
                       subsequent Contingency Event. The "Base Amount" shall be
                       an amount equal to the number of Parent Securities owned,
                       directly or indirectly, by the Liberty Group immediately
                       prior to the Merger (including the 2 million shares of
                       Parent Class B Common Stock held by BDTV) together with
                       all Parent Securities actually issued to Liberty HSN in
                       the Merger (including any Parent Stock issued pursuant to
                       the adjustment contemplated by Section 2.1(f) of the
                       Merger Agreement, but excluding any Contingent Parent
                       Shares or any Parent Securities issuable pursuant to the
                       Exchange Agreement). The "Adjusted Base Amount" shall be
                       the Base Amount plus the number of Contingent Parent
                       Shares issued to Liberty HSN subsequent to the Merger and
                       prior to such Contingent Issuance Event by Parent. For
                       purposes of this Exhibit A, Liberty HSN shall be deemed
                       to be entitled to own Additional Shares indirectly to the
                       extent that Liberty HSN would, following its receipt of
                       such Additional Shares, be entitled to contribute such
                       shares to a BDTV Entity on a tax free basis. 

                       The term Contingent Issuance Event would include, but
                       would not be limited to, the occurrence of one of the
                       following events, or the existence of any of the
                       following circumstances:

Calculation of 
Available
Share Amount:          The number of Additional Shares issuable to Liberty HSN
                       upon the occurrence of a Contingent Issuance Event shall
                       be equal to the "Available Share Amount," which shall be
                       calculated in accordance with the following formula:

                             issuances of Parent Securities resulting in or
                             contributing to the occurrence of the Contingent
                             Issuance Event, but excluding (i) the issuance of
                             the Additional Shares to Liberty HSN as a result of
                             such Contingent Issuance Event and (ii) any shares

                       ABA = the Adjusted Base Amount immediately prior to the
                             occurrence of the Contingent Issuance Event.

                       Notwithstanding the foregoing, Parent shall not be
                       required to issue Contingent Parent Shares to Liberty HSN
                       unless the number of Additional Shares then issuable
                       (together with any Contingent Parent Shares that have
                       previously become issuable to Liberty HSN pursuant to
                       this Exhibit A but for the application of this sentence)
                       exceeds 5,000; provided, however, that any such

                       Contingent Parent Shares exceeds such

                       Additional Shares shall be issued to Liberty HSN.

Approved Issuance:     In the event that there are any Remaining Shares Issuable
                       (as defined below) which cannot be issued solely due to a
                       required approval, consent or waiver from the FCC on the
                       third anniversary of the Merger, then on and after such
                       third anniversary until such time as there are no
                       Remaining Shares Issuable, Liberty HSN shall have the
                       right to make application to the FCC for such consent or
                       approval as may be necessary to permit the issuance to it
                       of some or all of the Remaining Shares Issuable for the
                       purpose of the disposition of such securities by Liberty
                       HSN in an orderly manner over a specified period of time
                       or by a date certain (such consent or approval of the
                       FCC, the "FCC Issuance Approval"). Liberty HSN shall be
                       entitled to seek such FCC Issuance Approval from time to
                       time following the third anniversary of the Merger and to
                       make all applicable determinations relating to the form
                       and substance of the consent or approval sought,
                       including, without limitation, the number of Remaining
                       Shares Issuable for which such consent or approval is to
                       be sought. The right to seek the FCC Issuance Approval
                       shall not limit Liberty HSN's right to have Contingent
                       Parent Shares issued to it upon the occurrence of a
                       Contingent Issuance Event subsequent to such third
                       anniversary, nor shall it limit Parent's obligations
                       regarding its efforts to cause all Remaining Shares
                       Issuable to be issued consistent with the terms hereof,
                       and in this regard Parent and Liberty HSN agree to
                       cooperate in good faith in order to provide for the
                       orderly issuance of Contingent Parent Shares and Approved
                       Shares pursuant to the Contingent Issuance Right.. Parent
                       agrees that it will use its reasonable best efforts to
                       support any request or application for a FCC Issuance
                       Approval made by Liberty HSN .

                       Following the receipt of any FCC Issuance Approval Parent
                       shall, upon the request of Liberty HSN and upon the date
                       reasonably specified by Liberty, issue to it up to the
                       number of Contingent Parent Shares for which such
                       approval has been granted, including therein a number of
                       shares of Parent Class B Common Stock equal to the Extra
                       Share Amount; subject, however, to any limitation

                       contained in the FCC Issuance Approval as to the
                       aggregate number of shares to be so issued. Upon each
                       issuance of Contingent Parent Shares pursuant to a FCC
                       Issuance Approval and the subsequent taxable sale of such
                       shares, Parent shall issue to

                       Liberty HSN an additional number of shares (the "Extra
                       Share Amount," and such shares, the "Extra Shares") of
                       Parent Class B Common Stock such that after such taxable
                       sale of all Contingent Parent Shares and Extra Shares so
                       issued (collectively, the "Approved Shares"), Liberty HSN
                       (or its permitted assignee) would have net after-tax
                       proceeds equal to the total fair market value of the
                       Contingent Parent Shares as of the date of receipt of
                       such shares. Prior to the first issuance of shares
                       pursuant to the FCC Issuance Approval, Parent and Liberty
                       HSN shall enter into a registration rights agreement
                       providing to Liberty HSN customary terms for the
                       registration of the Approved Shares issuable, including,
                       but not limited to, reasonable demand and piggyback
                       registration rights, minimum amounts of shares to be
                       offered, and other customary and reasonable provisions,
                       in light of the number of Remaining Shares Issuable. Such
                       agreement shall provide that Liberty HSN shall have a
                       single special demand right which shall entitle it to
                       require Parent to use its commercially reasonable best
                       efforts to register the full amount of shares requested
                       to be registered and shall require Parent to use its best
                       efforts to cause such registration to become effective on
                       or as near as possible, to the date of an FCC Issuance
                       Approval. Parent agrees that upon the request of Liberty
                       HSN it will file a registration statement relating to the
                       sale by Liberty HSN of such Approved Shares (upon
                       conversion thereof to shares of Parent Common Stock)
                       under the Securities Act of 1933, as amended, and shall
                       use its best efforts to cause such registration statement
                       to become effective upon the date of issuance, or to
                       register such shares for sale pursuant to a "shelf"
                       registration statement, and to use its reasonable best
                       efforts to cause such registration to remain effective
                       during the distribution period therefor.

                       Notwithstanding the above, the total number of Contingent
                       Parent Shares issued or shares otherwise issuable
                       pursuant to this Exhibit A cannot exceed the number of
                       shares of Parent Class B Common Stock issued in the
                       Merger at the Effective Time. The previous sentence shall
                       be applied by taking into account the effect of stock
                       splits, recapitalizations and similar transactions. The
                       "Remaining Shares Issuable" as of any date shall be equal
                       to the number of Contingent Parent Shares issuable to
                       Liberty HSN immediately following the Effective Time of
                       the Merger less the number of Contingent Parent Shares
                       which have been issued to Liberty HSN as of such date
                       (and shall exclude any Extra Shares issued to it).

Anti-Dilution
Adjustments:           The number of Remaining Shares Issuable shall be subject
                       to adjustment upon the occurrence of certain events
                       involving Parent including, without limitation: (i) the
                       payment by Parent of dividends (and other distributions)
                       on outstanding shares of Parent Securities in cash (or
                       other property) or shares of Parent's capital stock; (ii)
                       subdivisions or combinations of Parent Securities; (iii)
                       the issuance by Parent, in reclassification of its
                       outstanding shares of Parent Securities, of any other
                       shares of capital stock of Parent; and (iv) the
                       distribution by Parent to the holders of Parent
                       Securities of any assets, properties or debt securities
                       or any rights, warrants or options to purchase
                       securities.

Disputes Concerning
Occurrence of
Contingent Issuance 
Events:                The determination of whether or not a Contingent Issuance
                       Event exists or has occurred, and the determination of
                       the number of Additional Shares issuable as a result
                       thereof, shall be made in the good faith reasonable
                       determination of Parent based upon FCC Regulations (as
                       then in effect). In the event of any dispute between
                       Parent and Liberty HSN with respect to the existence or
                       occurrence of a Contingent Issuance Event, or the
                       determination of the number of Additional Shares issuable
                       in connection therewith, such dispute may be resolved by
                       means of the delivery to Parent and Liberty HSN of a
                       written opinion addressed to each of Parent and Liberty
                       HSN (which opinion shall be in form and substance
                       reasonably satisfactory to Parent and Liberty HSN and
                       shall not be subject to material qualifications or
                       limitations) of counsel to Parent specializing in FCC
                       matters as to the matters that are the subject of any
                       such dispute.

                       Notwithstanding any other provision of the Agreement
                       (including this Exhibit A), but excluding the

                       other rights of Liberty HSN under the Agreement, until
                       such time as there are no longer any Remaining Shares
                       Issuable, without the consent of Liberty HSN, Parent will
                       not (and will not cause or permit any of its subsidiaries
                       to) take any action that would, or could reasonably be
                       expected to, or fail to take any action which failure

                       ownership of the Contingent Parent Shares or the
                       existence or continuation of the Contingent Right or the
                       ownership by the Liberty Group of its other material
                       assets or the operation of its businesses (provided, that

                       the consummation of a transaction by the Liberty Group
                       would result in BDTV, Parent, or any of their respective
                       subsidiaries being in breach or violation of any law,

                       taxable to Liberty HSN or any member of the Liberty
                       Group; provided, however, that with respect to clauses
                              --------  ------- 
                       (ii) and (iii) hereof, if (x) such creation, existence,

                       or a member of the Liberty Group (other than due to an

                       payable by Liberty HSN had all of the Contingent Parent
                       Shares been issued to Liberty HSN in the Merger at the
                       Effective Time, then the covenants set forth in such

                       Contingent Parent Shares at any time. In addition to the
                       foregoing, so long as there are any Remaining Shares
                       Issuable, Parent shall not (a) declare or pay any cash
                       dividends, or make any distribution of its properties or
                       assets to the holders of the Parent Securities (other
                       than a distribution that is tax-free to the holders of
                       Parent Securities), unless prior thereto, Parent shall
                       have made arrangements reasonably acceptable to Liberty
                       HSN to protect it with respect to any adverse tax
                       consequence incurred by Liberty HSN (other than its
                       obligation to pay tax solely because of and to the extent
                       of the holder's receipt of such dividend or distribution)
                       resulting from the declaration and payment of such
                       dividend or the making of such distribution, or (b)(i)

                       person, (ii) sell or transfer to another corporation or
                       other person the property of Parent as an entirety or
                       substantially as an entirety, or (iii) engage in any
                       statutory exchange of Parent Securities with another
                       corporation or other person (other than in connection
                       with a merger or acquisition), in each case as a result
                       of which shares of Parent Securities would be
                       reclassified or converted into the right to receive
                       stock, securities or other property (including cash) or

                       connection with any such transaction (and immediately
                       prior to the consummation thereof) all Remaining Shares
                       Issuable are issuable (and are issued) to Liberty HSN and
                       Liberty HSN would be entitled to own and exercise full
                       rights of ownership of such Parent Securities following
                       such transaction or Liberty HSN would be entitled to own
                       and exercise full rights of ownership of the stock,

                       the number and kind of Parent Securities receivable by it
                       upon the issuance to it of such Remaining Shares
                       Issuable. Parent shall not become a party and shall not
                       permit any of its subsidiaries to become a party to any
                       transaction with respect to the foregoing unless the
                       terms of the agreements relating to such transaction
                       include obligations of the applicable parties consistent
                       with the foregoing. If the issuance of Contingent Parent
                       Shares is taxable to Liberty HSN as a result of a change
                       in law after the Effective Time (but not due to an action
                       or unreasonable inaction by Liberty HSN or the Liberty
                       Group referred to in clause (ii)(x)(1) of the second
                       sentence under "Parent Obligation"), Parent acknowledges
                       and agrees that it shall be obligated to provide to
                       Liberty HSN upon each issuance of Contingent Parent
                       Shares, a number of additional shares sufficient on an
                       after-tax basis to pay any such resulting tax.

Expiration:            Parent's obligation to issue Contingent Parent Shares,
                       Remaining Shares Issuable or Extra Shares shall terminate
                       at the close of business on the fifth anniversary of the
                       Effective Time.

Miscellaneous:         Whenever it is necessary for purposes of this Exhibit to
                       determine whether an issuance of Contingent Parent Shares
                       is taxable or tax-free, such determination shall be made
                       without regard to any interest imputed pursuant to
                       Section 483 of the Code.

Gentlemen:

          I have been advised that as of the date of this letter I may be deemed
to be an "affiliate" of Home Shopping Network, Inc., a Delaware 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 November 27, 1995 (the "Agreement"), by
                                                                 ---------      
and among Silver King Communications, Inc., a Delaware corporation ("Parent"),
                                                                     ------   
House Acquisition Corp., a Delaware 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 (the "Parent Securities").  I would receive such
                                      -----------------                         
shares in exchange for shares (or options for shares) owned by me of common
stock, par value $.01 per share, of the Company (the "Company Securities").
                                                      ------------------   

          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
     stockholders 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 

                                      -1-
<PAGE>
 
     sale, transfer, assignment or other disposition is otherwise exempt from
     registration under the Act.

          4.  I understand that Parent is under no obligation to register the
     sale, transfer, assignment or other disposition of the 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 APPLIED.  THE SHARES REPRESENTED BY THIS CERTIFICATE MAY ONLY BE
          TRANSFERRED IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT DATED AUGUST
          25, 1996 BETWEEN THE REGISTERED HOLDER HEREOF AND SILVER KING
          COMMUNICATIONS,  INC., A COPY OF WHICH AGREEMENT IS ON FILE AT THE
          PRINCIPAL OFFICES OF SILVER KING COMMUNICATIONS,  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 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 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.

          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

that I am such an affiliate on or after the date of this letter.

               TERMS AND CONDITIONS REGARDING EXCHANGE AGREEMENT
               --------------------------------------------------
        BETWEEN SILVER KING COMMUNICATIONS, INC. AND LIBERTY HSN, INC.
        --------------------------------------------------------------


          The following provisions are intended to summarize the terms and
conditions of the Exchange Agreement to be entered into between Parent and
Liberty HSN. The merger and exchange agreement to which this Exhibit C is
attached (the "Agreement") contemplates that the agreements contained herein
will be superseded by a definitive Exchange Agreement which will contain
provisions incorporating and expanding upon the agreements set forth herein,
together with other provisions customary in the case of transactions of this
type, and such other provisions as are reasonable and appropriate in the context
of the transactions contemplated hereby.  Parent and Liberty HSN shall use
commercially reasonable efforts to consummate the transactions contemplated
hereby, including, without limitation, the satisfaction of the respective
conditions to the parties' obligations to consummate such transactions and the
completion of such definitive agreements. Capitalized terms not defined herein
shall have the meanings ascribed to such terms in the Agreement.

Exchange Right:     In connection with the consummation of the Merger, the
                    Liberty Group (or any permitted transferee) shall receive
                    739,141 shares of Surviving Corporation Class B Common Stock
                    and 17,566,702 shares of Surviving Corporation Common Stock,
                    subject to adjustment as provided in Section 2.1(f) of the
                    Merger Agreement (such shares issued to the Liberty Group,
                    the "Liberty Surviving Common" and the "Liberty Surviving
                    Class B", respectively, in each case including any other
                    securities or rights for which such shares of Liberty
                    Surviving Common or Liberty Surviving Class B, as the case
                    may be, are exchanged or into which such shares are
                    converted prior to the exchange of such shares for Parent
                    Securities). "Parent Securities" shall mean, collectively,
                    all equity securities of Parent, including any securities
                    exercisable or exchangeable for or convertible into equity
                    securities of Parent. Pursuant to the Exchange Agreement,
                    the members of the Liberty Group (or any transferee) will
                    have the right to exchange such shares of Liberty Surviving
                    Class B for shares of Parent Class B Common Stock and such
                    shares of Surviving Corporation Common Stock for shares of
                    Parent Common Stock from time to time as provided below.

                    The Liberty Group shall have the right to exchange from time
                    to time, a number of shares of Liberty Surviving Common or
                    Liberty Surviving Class B (with the holder entitled to elect
                    the class of Surviving

                    Corporation stock to be so exchanged), which would result in
                    the issuance to such holder of a number of Parent Securities
                    equal to the then Available Parent Amount. The "Available
                    Parent Amount" will equal the difference between (x) the
                    maximum number of Parent Securities which the holder of the
                    Liberty Surviving Common or Liberty Surviving Class B
                    (collectively, the "Exchange Securities") would, under the
                    FCC Regulations then in effect, then be entitled to own, and
                    (y) the number of Parent Securities then owned (for purposes
                    of the FCC Regulations) by such holder of Exchange
                    Securities; provided, that in determining the foregoing, a
                                --------                    
                    holder shall not be deemed to be permitted to own shares
                    pursuant to the FCC Regulations to the extent that such
                    exchange would result in any limitation or restriction
                    relating to the continuation of such ownership following the
                    exchange of such Exchange Securities, or the imposition of
                    any restriction or limitation of the type referred to in
                    clause (i) of the first sentence of the last paragraph
                    opposite the caption "Parent Covenants" or any requirement
                    to dispose or divest of any Parent Securities (including any
                    interest in BDTV, BDTV II or any BDTV Entity (each as
                    defined in the Term Sheet)) in connection with or as a
                    result of such exchange (any of the foregoing restrictions
                    or limitations a "Restrictive Condition")). The Exchange
                    Agreement will provide that (A) each share of Liberty
                    Surviving Common will be exchangeable into 0.45 shares of
                    Parent Common Stock (the "Common Stock Exchange Ratio") and
                    (B) each share of Liberty Surviving Class B will be
                    exchangeable into 0.54 shares of Parent Class B Common Stock
                    (the "Class B Common Stock Exchange Ratio"), in each case,
                    rounded down to the nearest whole number and subject to
                    adjustment as provided herein.

                    Notwithstanding the foregoing, the parties' obligations to
                    exchange Exchange Securities for Parent Securities shall be
                    deferred to the extent that the number of Parent Securities
                    which would then otherwise be required to be issued upon
                    such exchange is less than 25,000; provided, however, that
                    any such Exchange Securities not then required to be
                    exchanged as a result of the provisions of this paragraph
                    shall be exchanged at such time as such number of Parent
                    Securities issuable upon the exchange of all Exchange
                    Securities then required to be exchanged equals or exceeds
                    such number, at which time, subject to the other conditions
                    herein, the parties shall execute such exchange.

Conditions to
Exchange:           The obligation of the holder of Exchange Securities to
                    consummate any such exchange pursuant to the Exchange
                    Agreement shall be subject to customary conditions of
                    closing, including but not limited to, (i) the receipt of
                    any and all consents, approvals or authorizations of any
                    governmental or regulatory entities, and the expiration or
                    termination of

                    any waiting periods under the HSR Act required in connection
                    with the exchange of such Exchange Securities, and (ii) such
                    exchange not being taxable to Liberty HSN; provided,
                                                               --------         
                    however, that the condition to exchange Exchange Securities
                    -------
                    set forth in this clause (ii) shall be deemed satisfied to
                    the extent that (x) the taxability of such exchange to
                    Liberty HSN is a result of (1) any action or inaction by
                    Liberty HSN or a member of the Liberty Group (other than due
                    to an action or inaction specifically contemplated or
                    required by the Merger Agreement, the Exchange Agreement,
                    the Term Sheet or the August Agreement (as defined in the
                    Term Sheet)) or (2) the laws and regulations in effect at
                    the Effective Time, or (y) the taxes applicable to such
                    exchange would have accrued or been payable by Liberty HSN
                    had all of the Exchange Securities been issued to Liberty
                    HSN in the Merger at the Effective Time. Each of Parent and
                    Liberty HSN shall use their reasonable best efforts to
                    obtain any such required consent or approval, and to file
                    and cause the expiration or termination of any waiting
                    period required in accordance with the HSR Act, in each case
                    as promptly as practicable.


Assignment:         The rights of the Liberty Group under the Exchange Agreement
                    shall be assignable to any person acquiring Exchange
                    Securities (or any interest therein (including an interest
                    in any BDTV Entity) in a transfer made pursuant to the
                    August Agreement (treating the Exchange Securities as though
                    they were Silver Securities (as defined in the August
                    Agreement)).

Anti-Dilution
Adjustments:        The Common Stock Exchange Ratio and the Class B Common Stock
                    Exchange Ratio shall be subject to adjustment upon the
                    occurrence of certain events involving Parent including,
                    without limitation: (i) the payment by Parent of dividends
                    (and other distributions) on outstanding shares of Parent
                    Securities in cash or shares of Parent's capital stock; (ii)
                    subdivisions or combinations of Parent Securities; (iii) the
                    issuance by Parent, in reclassification of its outstanding
                    shares of Parent Securities, of any other shares of capital
                    stock of Parent, and (iv) the distribution by Parent to
                    holders of Parent Securities of any assets, properties or
                    debt securities or any rights, warrants or options to
                    purchase securities.

Certain Fundamental
Transactions:       The Exchange Agreement will also provide that in the event
                    of any merger, consolidation, statutory exchange of
                    securities or other recapitalization or reclassification of
                    the securities of the Surviving

                    Corporation, or a sale or transfer of all or substantially
                    all of the assets of the Surviving Corporation, the
                    securities or other property receivable by the holder of the
                    Exchange Securities in such transaction will be exchangeable
                    for shares of Parent Common Stock or Parent Class B Common
                    Stock upon the same terms and conditions as such shares of
                    Liberty Surviving Common and Liberty Surviving Class B
                    (including, without limitation, any adjustments to the
                    Common Stock Exchange Ratio and the Class B Common Stock
                    Exchange Ratio).

                    Except as provided in the next sentence, the terms of the
                    Exchange Agreement shall provide that no shares of Liberty
                    Surviving Common or Liberty Surviving Class B shall be
                    exchanged with a member of the Liberty Group under the
                    Exchange Agreement until all Contingent Parent Shares
                    issuable to Liberty HSN pursuant to the Contingent Right
                    (each as defined in Exhibit A to the Agreement) have been so
                    issued. Notwithstanding the foregoing, and in addition to
                    its right to assign its rights under the Exchange Agreement
                    to any permitted transferee of Exchange Securities (or
                    interests therein), the Exchange Agreement shall also
                    provide that any member of the Liberty Group shall be
                    permitted to exchange the applicable amount of Exchange
                    Securities held by it in connection with any direct or
                    indirect transfer of Parent Securities issuable upon such
                    exchange by such member of the Liberty Group to one or more
                    third parties in accordance with the Silver Stockholders
                    Agreement (including in connection with a public offering of
                    Parent Securities effected pursuant to the Liberty Group's
                    demand and piggyback registration rights under the Silver
                    Stockholders Agreement).

Parent Covenants:   In the Exchange Agreement, Parent shall agree that so long
                    as any Exchange Securities remain outstanding it shall
                    provide to Liberty HSN quarterly and annual financial
                    statements and reports (including a balance sheet and
                    related income statement and the notes related thereto)
                    prepared with respect to the Surviving Corporation and such
                    additional financial and other information with respect to
                    the Surviving Corporation and its subsidiaries as Liberty
                    HSN may from time to time reasonably request.

                    Notwithstanding any other provision of the Exchange
                    Agreement or the Agreement to the contrary (but excluding
                    actions specifically contemplated by the Exchange Agreement
                    and the Agreement), and in addition to the foregoing rights
                    and any other voting rights granted by law to the holders of
                    the Exchange Securities, without the consent of Liberty HSN
                    (which consent, in the case of clauses (ii) through (v)
                    below, will not be unreasonably withheld), Parent will not
                    (and will not cause or permit

                    Corporation or any of its subsidiaries to take any action
                    that would, or could reasonably be expected to, or fail to
                    take any action which failure would or could reasonably be
                    expected to, (i) make the ownership by the Liberty Group of
                    the Exchange Securities or any other material assets thereof
                    unlawful or result in a violation of any law, rule,
                    regulation, order or decree (including the FCC Regulations)
                    or impose material additional restrictions or limitations on
                    the Liberty Group's full rights of ownership of the Exchange
                    Securities or the ownership of its other material assets or
                    the operation of its businesses (provided, that for purposes

                    Corporation or their respective subsidiaries relates to or
                    is based upon or would arise as a result of, any action or
                    the consummation of a transaction by the Liberty Group, such
                    condition, restriction or limitation shall be deemed to be
                    such a condition, restriction or limitation on the Liberty
                    Group (regardless of whether it is a party to or otherwise
                    would be legally obligated thereby) to the extent that the
                    taking of an action or the consummation of a transaction by
                    the Liberty Group would result in BDTV, Parent, or any of
                    their respective subsidiaries being in breach or violation
                    of any law, rule, regulation, order or decree or otherwise
                    causing such rule, regulation, order or decree to terminate
                    or expire or would otherwise result in Liberty HSN's
                    ownership of the Exchange Securities or any other material
                    assets being illegal or in violation of any law, rule,
                    regulation, order or decree), (ii) cause the acquisition or
                    ownership by the Liberty Group of any Exchange Securities
                    (upon the Exchange pursuant to Section 1.1 of the Agreement
                    immediately prior to the Effective Time or upon any
                    subsequent exchange or conversion of Liberty Surviving
                    Common or Liberty Surviving Class B) to be taxable to such
                    holder; (iii) cause the exchange of Exchange Securities for

                    Liberty HSN had all of the Exchange Securities been issued
                    to Liberty HSN in the Merger at the Effective Time, then the
                    covenants set forth in such clause (ii) or (iii) shall not
                    be effective; (iv) result in the Surviving Corporation being

                    right or ability of a holder of Exchange Securities at any
                    time to exercise the exchange rights under the Exchange
                    Agreement. In addition to the foregoing, the Exchange
                    Agreement will provide that so long as any Exchange
                    Securities are outstanding, Parent shall not declare or pay
                    any cash dividends, or make any distribution of its
                    properties or assets to the holders of Parent Securities
                    (other than a distribution which is tax free to the holders
                    of Parent Securities), unless prior thereto Parent shall
                    have made arrangements reasonably acceptable to the holders
                    of the Exchange Securities to protect such holders with
                    respect to any adverse tax consequence incurred by such
                    holder (other than the obligation of such holder to pay tax
                    solely because of the holder's receipt of such dividend or
                    distribution) resulting from the declaration and payment of
                    such dividend or the making of such distribution. In
                    addition, the Exchange Agreement will provide that, so long
                    as any Exchange Securities are outstanding, Parent will not
                    (i) merge with or into any person, or consolidate with any
                    person, (ii) sell or transfer to another corporation or
                    other person the property of Parent as an entirety or
                    substantially as an entirety, or (iii) engage in any
                    statutory exchange of Parent Securities with another
                    corporation or other person (other than in connection with a
                    merger or acquisition), in each case as a result of which
                    shares of Parent Securities would be reclassified or
                    converted into the right to receive stock, securities or
                    other property (including cash) or any combination thereof,
                    unless in connection with any such transaction (and
                    immediately prior to the consummation thereof) the holder of
                    the Exchange Securities would be entitled to exchange all
                    Exchange Securities for Parent Securities (and own and
                    exercise full rights of ownership of such Parent Securities
                    following such transaction) or the holder of such Exchange
                    Securities would be entitled to own and exercise full rights
                    of ownership of the stock, securities or other property
                    receivable by a holder of the number and kind of Parent
                    Securities receivable by such holder upon such exchange of
                    Exchange Securities. Parent shall not become a party and
                    shall not permit any of its subsidiaries to become a party
                    to any transaction with respect to the foregoing unless the
                    terms of the agreements relating to such transaction include
                    obligations of the applicable parties consistent with the
                    foregoing.

Transfer of
Surviving
Corporation's
Assets and
Liabilities to
Subsidiary:         Parent agrees that as soon as reasonably practicable
                    following the Merger, it will use its reasonable best
                    efforts to take and cause any of its subsidiaries to take
                    any actions necessary in order to assign to a wholly owned
                    subsidiary of the Surviving Corporation ("Surviving Sub")
                    all of the material assets (other than the capital stock of
                    Surviving Sub) and material liabilities of the Surviving
                    Corporation and to cause Surviving Sub to assume or
                    guarantee all such material liabilities and to obtain the
                    release of the Surviving Corporation from all such material
                    liabilities. Following such transfer, Parent shall not
                    permit the Surviving Corporation to own any assets other
                    than the capital stock of the Surviving Sub, and shall not
                    permit the Surviving Corporation to be or become subject to
                    any material liabilities.

Certain Obligations
Upon Insolvency or
Bankruptcy of
Surviving
Corporation:        In the event that the Surviving Corporation should become
                    insolvent or, within the meaning of any federal or state
                    bankruptcy law, commence a voluntary case or consent to the
                    entry of any order of relief or for the appointment of any
                    custodian for its property or a court of competent
                    jurisdiction enters an order or decree for relief against
                    the Surviving Corporation appointing a custodian or ordering
                    its liquidation, and Liberty HSN determines in good faith
                    that the equity of the Surviving Corporation is reasonably
                    likely to be impaired or extinguished, then upon the request
                    of Liberty HSN, its rights under the Exchange Agreement
                    shall be converted into the deferred right to receive from
                    Parent the number of shares of Parent Common Stock and
                    Parent Class B Common Stock which Liberty HSN would then
                    have had the right to acquire upon the exchange of all
                    Exchange Securities then outstanding (such deferred right,
                    the "Additional Contingent Right"). The terms and conditions
                    of the Additional Contingent Right shall be identical to
                    those of the Contingent Right, except that the Remaining
                    Shares Issuable (as defined in Exhibit A to the Agreement)
                    pursuant to the Additional Contingent Right shall
                    automatically become issuable, subject to regulatory
                    approval, on the fifth anniversary of the date the
                    Additional Contingent Right is granted.

<PAGE>
 
                    In connection with the grant of the Additional Contingent
                    Right, Parent shall thereafter be obligated to use all
                    reasonable efforts to consummate a Restructuring Transaction
                    (as defined below) on or before the third anniversary of the
                    date of the grant of the Additional Contingent Right. In the
                    event that such Restructuring Transaction has not been
                    consummated by such fifth anniversary and the Additional
                    Contingent Right has not been satisfied in full by such
                    date, Parent shall thereafter be required to use its best
                    efforts to cause all Parent Securities issuable in respect
                    of the Additional Contingent Right to be issued prior to the
                    seventh anniversary thereof. Such efforts shall include,
                    without limitation (but subject to applicable fiduciary
                    obligations) engaging in a Restructuring Transaction,
                    completing an equity offering, or other corporate
                    restructuring or causing all of the equity interests in
                    Parent to be acquired by a third party in a transaction
                    which is tax free to the stockholders of Parent, in any case
                    which would result in all Contingent Parent Shares issuable
                    to Liberty HSN pursuant to the Additional Contingent Right
                    being issued to it and Liberty HSN being entitled to hold
                    such Parent Securities or other properties receivable by it
                    in such transaction free of any governmental or regulatory
                    restrictions and to exercise full rights of ownership with
                    respect thereto. A "Restructuring Transaction" is a
                    transaction pursuant to which Parent shall take such actions
                    as may be reasonably necessary, including, but not limited
                    to, to file any required applications with the FCC and any
                    other governmental or regulatory agency, to obtain any
                    required FCC or other governmental or regulatory consents
                    and approvals, and to undertake any restructuring of
                    Parent's assets, liabilities and businesses, in order that
                    Liberty or Liberty HSN, as the case may be, would (subject
                    to its obligations under the August Agreement, the Term
                    Sheet and the Silver Stockholders Agreement) be permitted to
                    exercise full ownership rights (including voting rights)
                    with respect to the Parent Securities owned by it (including
                    its pro rata interest in any Parent Securities held by BDTV,
                    BDTV II or a BDTV Entity).

Miscellaneous:      If the exchange of Exchange Securities is taxable to Liberty
                    HSN as a result of a change in law (but not due to an action
                    or unreasonable inaction by Liberty HSN or a member of the
                    Liberty Group referred to in clause (ii)(x)(1) of the first
                    sentence of "Conditions to Exchange") after the Effective
                    Time, Parent acknowledges and agrees that it shall be
                    obligated to provide to Liberty HSN upon each exchange of
                    Exchange Securities, a number of additional shares
                    sufficient on an after-tax basis to pay any such resulting
                    tax.

                    Whenever it is necessary for purposes of this Exhibit to
                    determine whether an exchange is taxable or tax-free, such
                    determination shall be made without regard to any interest
                    imputed pursuant to Section 483 of the Code.

                    Parent at all times shall reserve for issuance to Liberty
                    HSN a number of shares of Parent Class B Common Stock and
                    Parent Common Stock equal to the number of shares issuable
                    upon exchange of the remaining shares of Liberty Surviving
                    Class B and Liberty Surviving Common, respectively, and
                    shall reserve an additional number of shares of Parent
                    Common Stock equal to the number of shares issuable upon the
                    conversion of shares of Parent Class B Common Stock issuable
                    pursuant to the Exchange Agreement.

                    The Exchange Agreement will provide that Parent will grant
                    to the holder of Parent Securities issuable upon the
                    exchange of Exchange Securities certain rights relating to
                    the registration of such securities under the Securities Act
                    upon customary terms and conditions, including demand and
                    piggyback registration rights.

undersigned shall be permitted to pledge or grant a security interest in the

Mr. Barry Diller
1940 Coldwater Canyon
Beverly Hills, California 90210

Dear Sir:

          Reference is made to the agreement between Liberty Media Corporation
("Liberty" and formerly "Rockies") and Barry Diller ("Diller" and formerly
"Lasorda" or "Dodgers"), dated as of August 24, 1995 (including the related term
sheet included therein, the "August Agreement" which, in the event that a
definitive stockholders agreement is not executed by the parties shall, together
with this letter agreement (this "Agreement") constitute the "Silver
Stockholders Agreement"), relating to the securities of Silver King
Communications, Inc. ("Silver").  Capitalized terms not otherwise defined in
this Agreement shall have the meanings ascribed to such terms in the August
Agreement.  The obligations of the parties contained herein are subject to the
receipt of any required approvals of the Boards of Directors of Silver and/or
Home Shopping Network, Inc. ("HSN"), for purposes of Section 203 of the Delaware
General Corporation Law.

          1.     HSN Merger Agreement.
                 -------------------- 

          (a)    Simultaneous with the execution of this Agreement, a newly
                 formed direct wholly owned subsidiary of Silver ("Silver Sub"),
                 HSN and Liberty HSN, Inc. ("Liberty HSN") are entering into the
                 merger agreement attached to this Agreement as Exhibit A (such
                 agreement, including the schedules and exhibits thereto, the
                 "Merger Agreement"). The Merger Agreement provides among other
                 things that Silver Sub will merge with and into HSN (the
                 "Merger"), with the result that HSN, as the surviving
                 corporation in the Merger (the "Surviving Corporation"), would
                 become a subsidiary of Silver. Silver Sub shall have an equity
                 capital structure identical to that of HSN prior to the merger,
                 in that the shares of Silver Sub common stock ("Silver Sub
                 Common") will have the same rights, designations and
                 preferences as the common stock of HSN (the "HSN Common Stock")
                 and the Silver Sub Class B common stock ("Silver Sub Class B")
                 will have the same rights, designations and preferences as the
                 Class B common stock of HSN (the "HSN Class B Common Stock").
                 In the Merger:
<PAGE>
 
               (i)    Each outstanding share of HSN Common Stock (other than
                      shares held by Silver Sub) would be converted into the
                      right to receive 0.45 of a share of Silver Common Stock
                      (the "Common Exchange Ratio").

               (ii)   The 19,260,859 shares of HSN Class B Common Stock held by
                      Liberty HSN (the Liberty Initial Class B Shares"),
                      following the exchange referred to in clause (iii) below,
                      would be converted into the right of Liberty HSN, as the
                      holder of the Liberty Initial Class B Shares as of the
                      time of the Merger (or any wholly owned subsidiary of
                      Liberty HSN to which the Contingent Right (as defined
                      below) is assigned), to receive an aggregate of 10,400,863
                      shares of Silver Class B Stock (such number, the
                      "Aggregate Class B Amount") (which number shall be subject
                      to adjustment immediately prior to the Merger in
                      accordance with Section 2(f) of the Merger Agreement) plus
                      cash in lieu of fractional shares as provided in the
                      Merger Agreement. At the Effective Time (as defined in the
                      Merger Agreement) of the Merger, 7,756,564 shares of
                      Silver Class B Common Stock shall be issued to Liberty HSN
                      (the "Initial Merger Class B Amount"). Immediately
                      following the Effective Time, Silver will be obligated to
                      issue to Liberty HSN (or any wholly owned subsidiary to
                      which it has assigned the Contingent Right) an aggregate
                      of 2,644,299 shares of Silver Class B Common Stock (such
                      amount, the "Initial Contingent Class B Amount") upon the
                      occurrence of certain contingencies set forth in Exhibit A
                      to the Merger Agreement, together with such additional
                      number of shares of Silver Class B Common Stock as may be
                      required in order to fulfill its obligation with respect
                      to the issuance of Extra Shares (as defined in Exhibit A
                      to the Merger Agreement) in such Exhibit A. Liberty HSN's
                      right following the Merger to receive shares of Silver
                      Class B Common Stock in accordance with the terms and
                      conditions set forth in Exhibit A to the Merger Agreement
                      is hereinafter referred to as the "Contingent Right," and
                      the shares issuable to it upon the satisfaction of the
                      contingencies set forth in Exhibit A to the Merger
                      Agreement are hereinafter referred to as the "Contingent
                      Silver Shares."

               (iii)  The Merger Agreement provides that (A) immediately prior
                      to, but conditioned upon the consummation of the Merger,
                      Liberty HSN will exchange (the "Merger Exchange") (1) the
                      17,566,702 shares of HSN Common Stock held by the Liberty
                      Stockholder Group (the "Liberty HSN Common Shares") for an
                      equal number of shares of Silver Sub Common and (2) the
                      739,141 shares of HSN Class B Common Stock

                                       2
<PAGE>
 
                      held by the Liberty Stockholder Group (the "Liberty HSN B
                      Shares") for an equal number of shares of Silver Sub Class
                      B (with the result that at the time of the Merger, the
                      total number of outstanding shares of Silver Sub Common
                      and Silver Sub Class B shall be equal to the number of
                      outstanding shares of HSN Common Stock and HSN Class B
                      Common Stock immediately prior to the Merger, with Silver
                      owning a number of shares of Silver Sub Common and Silver
                      Sub Class B equal to the number of shares of HSN Common
                      Stock not held by the Liberty Stockholder Group and the
                      number of Liberty Initial Class B Shares, respectively,
                      and Liberty HSN owning all other outstanding equity
                      securities of Silver Sub (and Silver Sub shall have no
                      other outstanding securities)), and (B) in the Merger,
                      each outstanding share of Silver Sub Common shall be
                      converted into one share of common stock of the Surviving
                      Corporation ("Surviving Common") and each outstanding
                      share of Silver Sub Class B shall be converted into one
                      share of Class B common stock of the Surviving Corporation
                      ("Surviving Class B Stock"), with the shares of Surviving
                      Common and Surviving Class B Stock having the same rights,
                      designations and preferences as the Silver Sub Common
                      Stock and Silver Sub Class B, respectively.

               (iv)   To the extent that at the time of the Merger Exchange and
                      the Merger the Liberty Stockholder Group would be
                      permitted in accordance with the FCC Regulations (as
                      defined below) (and taking into account the Silver
                      Securities then beneficially owned by it) to own, directly
                      or, through a BDTV Entity (as defined below), indirectly,
                      a greater number of shares of Silver than the Initial
                      Merger Class B Amount, then such number of additional
                      Silver Securities shall also become issuable to the
                      Liberty Stockholder Group upon consummation of the Merger
                      (such shares, the "Additional Merger Shares"). The
                      Additional Merger Shares shall be issued to the Liberty
                      Stockholder Group in the Merger and upon issuance, shall
                      be applied first to reduce the Initial Contingent Class B
                      Amount on a share for share basis until such time as the
                      Initial Contingent Class B Amount is equal to zero (and,
                      in the event the Initial Contingent Class B Amount is
                      reduced to zero through the issuance of Additional Merger
                      Shares, Silver's obligation to issue Contingent Silver
                      Shares in connection with the Contingent Right shall be
                      terminated). In the event that the Initial Contingent
                      Class B Amount is reduced to zero and there remain
                      Additional Merger Shares issuable at the time of the
                      Merger, such remaining Additional Merger Shares shall be
                      issued to the Liberty Stockholder Group and upon issuance

                      reduce on a share for share basis (A) first, to the
                      obligation of Liberty HSN and Silver Sub to exchange the
                      Liberty HSN B Shares for shares of Silver Sub Class B and
                      (B) then, to the extent that there are any remaining
                      Additional Merger Shares to be issued, to the obligation
                      of Liberty HSN and Silver Sub to exchange Liberty HSN
                      Common Shares for shares of Silver Sub Common, with the
                      result that the Liberty HSN Class B Shares and Liberty HSN
                      Common Shares not so exchanged would be converted into
                      Silver Class B Stock and Silver Common Stock,
                      respectively, in the Merger, and the respective
                      obligations of the parties referred to in clauses (i)
                      through (iii) above would be adjusted to reflect the
                      issuance of such Additional Merger Shares.

               (v)    Subject to the condition that the contribution thereto
                      would be tax free, all Additional Merger Shares would be
                      issued to the Liberty Stockholder Group and contributed to
                      a BDTV Entity in connection with the Merger. As used
                      herein, the term "BDTV Entity" shall mean any corporation,
                      partnership, limited liability company or other business
                      association having a capital structure and governance
                      rights substantially similar to that of BDTV, Inc.
                      ("BDTV", which is the corporation referred to as "Silver
                      Company" in the August Agreement), except that (i) for
                      purposes of determining whether Liberty is permitted to
                      transfer the Silver Securities held by any such BDTV
                      Entity, such BDTV Entity shall be deemed to be a member of
                      the Liberty Stockholder Group and the restrictions on
                      transfers of interests in the Silver Company set forth
                      opposite the caption "I. Silver Company Arrangements --
                      Transfers of Interests" in the August Agreement shall not
                      be applicable to Liberty (subject, however, to the other
                      restrictions on transfer of Silver Securities set forth
                      herein and in the August Agreement, including the Right of
                      First Refusal) and (ii) in connection with any proposed
                      sale by Liberty HSN of the Silver Securities held by such
                      BDTV Entity (or its equity interest in such BDTV Entity),
                      Liberty shall be entitled to purchase Diller's entire
                      interest in such BDTV Entity for an amount in cash equal
                      to the Dodgers Interest Purchase Price or, at its
                      election, require Diller to sell its interest in such BDTV
                      Entity to any such transferee for a pro rata portion of
                      the consideration to be paid by the applicable transferee
                      in such transaction; provided, however, that the term
                                           --------  ------- 
                      "BDTV Entity" shall not be deemed to include BDTV or BDTV
                      II (as defined below). The term "FCC Regulations" shall
                      mean, collectively, all federal communications statutes,
                      and all rules, regulations, orders, decrees and policies
                      (including the FCC's

                      Memorandum Opinion and Order released March 11, 1996 (the
                      "FCC March Order") and its Memorandum Opinion and Order
                      released June 14, 1996 (the "FCC June Order", and together
                      with the FCC March Order, the "FCC Orders")) of the FCC,
                      and any interpretations or waivers thereof or
                      modifications thereto.

               (vi)   If as a result of any issuance of Contingent Silver Shares
                      to Liberty HSN, Liberty HSN would otherwise own shares of
                      Silver Class B Common Stock (other than any such shares
                      held by BDTV or BDTV II or, to the extent Liberty HSN is
                      not deemed to have an "attributable interest" therein, a
                      BDTV Entity) which would represent an "attributable
                      interest" in Silver under applicable FCC Regulations), (i)
                      Liberty HSN would contribute to a BDTV Entity all such
                      Contingent Silver Shares in exchange for non-voting equity
                      securities of such BDTV Entity (in an amount based on the
                      market price of the Silver Common Stock as of the date of
                      such contribution) and (ii) Diller would contribute to
                      such BDTV Entity a number of whole shares of Silver Common
                      Stock equal to (A) $100, divided by (B) the market price
                      of the Silver Common Stock as of the date of such
                      contribution, rounded up to the nearest whole number;
                      provided, that (i) for purposes of determining whether
                      Liberty is permitted to transfer the Silver Securities
                      held by such BDTV Entity, such BDTV Entity shall be deemed
                      to be a member of the Liberty Stockholder Group and the
                      restrictions on transfers of interests in BDTV set forth
                      in the August Agreement shall not apply to Liberty
                      (subject, however, to the other restrictions on transfer
                      of Silver Securities set forth herein and in the August
                      Agreement, including the Right of First Refusal) and (ii)
                      in connection with any proposed sale by Liberty HSN of the
                      Silver Securities held by such BDTV Entity (or its equity
                      interest in such BDTV Entity), Liberty shall be entitled
                      to purchase Diller's entire interest in such BDTV Entity
                      for an amount in cash equal to the Dodgers Interest
                      Purchase Price or, at its election, require Diller to sell
                      its interest in such BDTV Entity to any such transferee
                      for a pro rata portion of the consideration to be paid by
                      the applicable transferee in such transaction.

          (b)  Consummation of the Merger will also be conditioned upon Silver
               and Liberty HSN entering into a definitive exchange agreement
               having the terms and conditions set forth in Exhibit C to the
               Merger Agreement (the "Exchange Agreement"), and otherwise in
               form and substance reasonably satisfactory to the parties to the
               Merger Agreement, pursuant to which the Liberty Stockholder Group
               (or any transferee permitted under the August

                                       5
<PAGE>
 
               Agreement, treating the Exchange Securities (as defined in
               Exhibit C to the Merger Agreement) as though they were Silver
               Securities) would have the right to exchange from time to time a
               number of shares of Surviving Common or Surviving Class B Stock
               (with the holder entitled to elect the class of Surviving
               Corporation stock to be so exchanged) received by the Liberty
               Stockholder Group in connection with the Merger (such shares
               issued to the Liberty Stockholder Group, the "Liberty Surviving
               Common" and the "Liberty Surviving Class B", respectively, in
               each case including any other securities or rights for which such
               shares of Liberty Surviving Common or Liberty Surviving Class B,
               as the case may be, are exchanged or into which such shares are
               converted prior to the exchange of such shares for Silver
               Securities), for shares of Silver Common Stock and Silver Class B
               Stock, with each share of Liberty Surviving Common being
               exchangeable into a number of shares of Silver Common Stock equal
               to the Common Exchange Ratio and each share of Liberty Surviving
               Class B being exchangeable into a number of shares of Silver
               Class B Stock equal to the Class B Exchange Ratio, in each case
               subject to adjustment upon certain events affecting Silver.

               In the event that a holder of Exchange Securities would be
               entitled to hold directly shares of Silver Class B Common Stock
               issuable upon an exchange of shares of Liberty Surviving Class B
               but for the limitations imposed by the FCC Regulations relating
               to a person's aggregate voting power in Silver, and if such
               person would, under the FCC Regulations, be permitted to hold
               directly a number of shares of Silver Common Stock equal to the
               number of shares of Silver Class B Stock so issuable, then in
               connection with such exchange, such holder will be required to
               offer to exchange such shares of Silver Class B Stock so
               receivable by it for Silver Common Stock owned by the Diller
               Stockholder Group and, if Diller does not accept such offer to
               exchange, or if such exchange with the Diller Stockholder Group
               cannot be accomplished on a tax-free basis (and the exchange of
               such Exchange Securities for Silver Securities would not
               otherwise be taxable), then such holder shall be entitled to
               exchange such Exchange Securities for shares of Silver Class B
               Stock and thereafter convert such shares of Silver Class B Stock
               into shares of Silver Common Stock.

               Nothing in this Agreement shall obligate Liberty HSN to
               contribute any Silver Securities received pursuant to the
               Exchange Agreement to a BDTV Entity.

          (c)  Promptly following the Merger in a transaction complying with the
               requirements of Section 351 of the Code or in an otherwise tax-
               free transaction, (i) Liberty will contribute the Initial Merger
               Class B Amount of

                                       6
<PAGE>
 
               shares of Silver Class B Common Stock issued to Liberty at the
               time of the Merger (other than any Additional Merger Shares) to a
               corporation ("BDTV II") having a charter and bylaws substantially
               equivalent to the charter and bylaws of BDTV as in effect on the
               date hereof (or, in the event the FCC Regulations would permit
               such Silver Securities to be held by a partnership, limited
               liability company or other entity, such entity as the parties may
               mutually agree), in exchange for a number of shares of Class B
               Common Stock of BDTV II based upon the market price of the shares
               of Silver Class B Stock contributed to BDTV II by the Liberty
               Stockholder Group and (ii) Diller will contribute to BDTV II a
               number of whole shares of Silver Common Stock equal to (A) $100
               divided by (B) the market price of the Silver Common Stock as of
               the date of contribution, rounded up to the nearest whole number,
               in exchange for one share of Class A Common Stock of BDTV II.  At
               all times following such contribution for purposes of this
               Agreement and the August Agreement the term "Silver Company" or
               "BDTV," as the case may be, shall be deemed to refer to BDTV and
               BDTV II, collectively. The respective rights and obligations of
               Liberty (and its Stockholder Group) and Diller (and his
               Stockholder Group) with respect to each of BDTV and BDTV II and
               the outstanding equity securities of both BDTV and BDTV II shall
               be as provided in the August Agreement with respect to "Silver
               Company", including, subject to paragraph 2(c) below, the
               provisions set forth in the August Agreement under the caption
               "I.  Silver Company Arrangements--Transfers of Interests."

          2.   Restructuring Transaction.  (a)  At any time following the
               -------------------------                                 
               consummation of the Merger that Liberty or Liberty HSN is no
               longer a subsidiary of Tele-Communications, Inc. (and provided
               that a Change in Law has not theretofore otherwise occurred),
               Liberty may request by written notice to Diller and Silver that
               Diller use all reasonable efforts to take, and, subject to any
               applicable fiduciary duties of Diller, as a director or officer
               of Silver, to the stockholders of Silver, use all reasonable
               efforts to cause Silver to take, such actions as may be
               reasonably necessary, including, but not limited to, to file any
               required applications with the FCC and any other governmental or
               regulatory agency, to obtain any required FCC or other
               governmental or regulatory consents and approvals, and to
               undertake any restructuring of Silver's assets, liabilities and
               businesses, in order that Liberty or Liberty HSN, as the case may
               be, would (subject to its obligations under the August Agreement,
               this Agreement and the Silver Stockholders Agreement) be
               permitted to exercise full ownership rights (including voting
               rights) with respect to the Silver Securities owned by it
               (including its pro rata interest in any Silver Securities held by
               the Silver Company or a BDTV Entity) (such

                                       7
<PAGE>
 
               action or transaction resulting from the foregoing, a
               "Restructuring Transaction").

          (b)  Simultaneously with or immediately following the consummation of
               the Restructuring Transaction, Liberty or its designee shall be
               required to purchase (and Diller will be required to sell)
               Diller's entire equity interest in the Silver Company and each
               BDTV Entity for an amount equal to the applicable Dodgers
               Interest Purchase Price.

          (c)  If a Restructuring Transaction has not occurred within 365 days
               following the notice referred to in paragraph 2(a) (or, if
               earlier, such time as Liberty reasonably determines, after
               consultation with Diller, that Diller has ceased to use his
               reasonable efforts to consummate a Restructuring Transaction as
               required by this Section 2), and a Change in Law has not
               otherwise occurred by such date, then notwithstanding the
               restrictions on transfer of the Silver Securities described under
               the caption "Transfers of Silver Securities" in the August
               Agreement, the Liberty Stockholder Group will be entitled to sell
               any and all of its Silver Securities (including its entire equity
               interest in the Silver Company or any BDTV Entity, or any
               Exchange Securities or Silver Securities receivable pursuant to
               the Exchange Agreement, but not any direct sale of Contingent
               Silver Shares issuable pursuant to the Contingent Right), subject
               only to (i) Diller's Right of First Refusal (as defined below),
               (ii) Liberty's obligation to exchange shares of Silver Class B
               Stock so proposed to be sold for shares of Silver Common Stock
               owned by the Diller Stockholder Group pursuant to the paragraph
               of the August Agreement entitled "Share Exchange" (but without
               regard to the limitation in the last sentence thereof), (iii)
               Liberty's further obligation to convert shares of Silver Class B
               Stock (or Surviving Class B Stock) into shares of Silver Common
               Stock (or Surviving Common) prior to or simultaneous with such a
               sale (other than to a member of the Diller Stockholder Group),
               and (iv) Diller's Special Purchase Right (as defined below). Such
               person or entity (other than a member of the Diller Stockholder
               Group) shall acquire such Silver Securities and/or interest in
               the Silver Company or such BDTV Entity free and clear of any
               rights or obligations under the August Agreement, this Agreement
               or the Silver Stockholders Agreement; provided, that such person
               or entity shall be entitled to such reasonable demand and
               incidental registration rights with respect to its Silver
               Securities (including those shares represented by its interest in
               the Silver Company or a BDTV Entity) as was the Liberty
               Stockholder Group under the August Agreement and/or the Silver
               Stockholders Agreement or this Agreement prior to such sale.
               Except as specifically provided in this paragraph, the sale by
               the Liberty Stockholder Group permitted herein will not otherwise
               alter the rights and obligations of

                                       8
<PAGE>
 
               the parties set forth in the August Agreement (as amended by this
               Agreement).

Right of First
Refusal and
Special 
Purchase 
Right          The term "Right of First Refusal" shall mean (for purposes
               of this Agreement and for purposes of the right of first refusal
               referred to in the August Agreement under the caption "Transfers
               of Silver Securities") the right of a Stockholder (which shall be
               assignable) to acquire all, but not less than all, of the
               securities proposed to be sold by the other Stockholder in a
               transaction having terms (including (except pursuant to the
               Special Purchase Right) net economic terms) and conditions no
               less favorable in the aggregate to the selling Stockholder than
               those of the transaction pursuant to which it intends to sell
               such securities.

               In the event that (x) a Stockholder proposes to sell Silver
               Securities  in a transaction in which the other Stockholder would
               have the right to exercise its Right of First Refusal to purchase
               all, but not less than all, of such shares to be sold, and (y)
               after giving effect to such sale and the requirement that the
               selling Stockholder convert all shares of Silver Class B Stock
               into Silver Common Stock upon such sale, the other Stockholder
               Group's beneficial ownership of Silver Securities would represent
               less than 50.1% of the outstanding voting power of the Silver
               Securities on a fully diluted basis, then subject to the
               satisfaction of the conditions set forth herein, a Stockholder
               shall have the right (the "Special Purchase Right") to purchase
               from such selling Stockholder such minimum number of Silver
               Securities (giving effect to the voting power thereof) as is
               required in order to result in the aggregate voting power of the
               Silver Securities beneficially owned or whose voting power is
               controlled by such Stockholder Group being equal to 50.1% of the
               voting power of the outstanding Silver Securities on a fully
               diluted basis.  A Stockholder's right to exercise the Special
               Purchase Right shall be subject to the condition that such
               Stockholder shall have (x) exercised all options, warrants,
               convertible securities and other rights to acquire Silver
               Securities as are beneficially owned by it and which are then (or
               will become prior to such sale) exercisable, and (y) exchanged
               with the other Stockholder all shares of Silver Common Stock
               beneficially owned by it for shares of Silver Class B Stock owned
               by the other Stockholder (to the extent such Stockholder owns
               shares of Silver Class B Stock), or in each case, made
               arrangements reasonably satisfactory to the other Stockholder in
               respect of such exercise, conversion or exchange (which will
               occur

                                       9

               simultaneously with the purchasing Stockholder's purchase from
               the other Stockholder).

               The purchase price for Silver Securities in connection with the
               exercise of the Special Purchase Right or the Right of First
               Refusal shall be equal to the price per share of Silver
               Securities to be paid to the selling Stockholder in the proposed
               transaction (as it may be adjusted in order to determine the net
               economic value thereof other than in the case of the Special
               Purchase Right). In the event that the consideration payable to a
               Stockholder in a proposed transaction consists of securities, the
               purchase price per share shall equal the fair market value of
               such securities divided by the number of shares of Silver
               Securities to be sold.  Such fair market value shall be the
               market price of any publicly traded security and, if such
               security is not publicly traded, the fair market value shall
               equal the Appraised Value.  A Stockholder (or its assignee) shall
               pay such purchase price in cash or by the delivery of marketable
               securities having an aggregate fair market value equal to such
               purchase price; provided that if the securities to be so
                               --------                                
               delivered by a Stockholder (or its assignee) would not, in the
               other Stockholder's possession, have at least the same general
               degree of liquidity as the securities the other Stockholder was
               to receive in such proposed transaction (determined by reference
               to the other Stockholder's ability to dispose of such securities
               (including, without limitation, the trading volume of such
               securities and the other Stockholder's percentage ownership of
               the issuer of such securities)), then the purchasing Stockholder
               shall be required to deliver securities having an Appraised Value
               equal to such purchase price.  In the event the purchasing
               Stockholder delivers securities in payment of such purchase
               price, the purchasing Stockholder agrees to provide the other
               Stockholder with registration rights related thereto (if, in the
               other transaction, the selling Stockholder would have received
               registered securities or registration rights). Each Stockholder
               agrees to use its commercially reasonable efforts to preserve to
               the other Stockholder, to the extent possible (except in the case
               of a Right of First Refusal where it is a condition thereto that
               such tax benefits be included in determining the net economic
               value of an offer pursuant to such right), the tax benefits
               available to it in such proposed transaction, and to otherwise
               seek to structure such transaction in the most tax efficient
               method available.  Notwithstanding the foregoing, in the event
               that the purchasing Stockholder pays the purchase price for
               Silver Securities purchased pursuant to the Right of First
               Refusal or the Special Purchase Right in securities, such
               securities must be securities that the other Stockholder is
               permitted to own under applicable FCC Regulations.

               Notwithstanding anything herein or in the August Agreement,
               Liberty HSN's sale on or after the third anniversary of the
               Merger of the Approved Shares (as defined in Exhibit A to the
               Merger Agreement) in an offering of Silver Common Stock
               registered under the Securities Act shall not be subject to the
               Right of First Refusal, the Special Purchase Right and Diller's
               right to exchange Silver Common Stock for shares of Silver Class
               B Stock, unless and to the extent such rights can be exercised
               without impairing Liberty's economic benefit therefrom or
               delaying any transaction relating to the Approved Shares.
               Subject to the foregoing, Liberty agrees to cooperate in good
               faith in the event Diller seeks to exercise such rights.

               Transaction (which will result in a Change in Law following the
               consummation thereof) and (y) a Change in Law (which the parties
               agree shall include, for purposes of this Agreement, the August
               Agreement, the Silver Stockholders Agreement, and the
               organizational documents of each of BDTV, BDTV II and any BDTV
               Entity, any change in law, rule or regulation, or change in the

               Stock (or Surviving Class B Stock) or of an interest in the
               Silver Company (or any BDTV Entity) or Silver (including, but not
               limited to, in the case of Liberty, a change in the ownership of
               a majority of the outstanding common stock of Liberty or Liberty
               HSN)) or any other event, the effect of which is or would be to
               permit Liberty or any holder of Liberty's interest in the Silver
               Company (or any BDTV Entity) to exercise ownership rights
               (including voting rights) with respect to the Silver Securities
               owned by it (including its pro rata portion of any Silver
               Securities held by the Silver Company or any BDTV Entity)), or
               which would otherwise result in the issuance to it of all
               Contingent Silver Shares and the exchange of all Exchange
               Securities, whether before or after the Merger, the management
               rights of the parties with respect to Silver shall be as follows:

               (i)    Diller thereafter would be entitled to designate a
                      mutually agreeable number of the members of the Board of
                      Directors of Silver and Liberty would be entitled to
                      designate the remainder of the directors of Silver (which
                      number designated by Liberty shall, in any event,
                      constitute a majority of the number of directors
                      constituting the entire Silver Board of Directors). In the
                      event that (A) any of Liberty's designees on the Silver
                      Board of Directors vote in a manner different than Diller
                      (or in the event that Diller is required to abstain from
                      voting under applicable law, different than Diller's
                      expressed preference) with respect to any matter voted
                      upon by the Silver Board

<PAGE>
 
                      of Directors, and the outcome of such vote is inconsistent
                      with Diller's vote (or such preference) solely as a result
                      of such different vote by any of such designees of Liberty
                      (except to the extent that such Liberty designees are
                      required under applicable law to abstain from voting) or
                      (B) any member of the Liberty Stockholder Group votes any
                      of its Silver Securities with respect to any matter
                      presented for a vote of the stockholders of Silver in a
                      manner inconsistent with the manner in which the Diller
                      Stockholder Group votes Silver Securities and the outcome
                      of such vote is inconsistent with the manner in which
                      Diller has voted, solely as a result of such different
                      vote by any such member of the Liberty Stockholder Group
                      (including, except as set forth below, decisions relating
                      to Diller's employment with Silver), in either case other
                      than (w) as specifically provided for by this Agreement,
                      the August Agreement or the Silver Stockholders Agreement
                      (including, without limitation, a Class B Issuance (as
                      defined below)), (x) any decision to terminate Diller's
                      employment with Silver for Cause, (y) any decision
                      relating to Diller's compensation by Silver or any of its
                      subsidiaries (except as provided for by the Silver Term
                      Sheet), or (z) any decision relating to a Fundamental
                      Matter (any such vote contrary to Diller's vote on such
                      preference other than as provided in clauses (w) (x), (y)
                      and (z) above, a "Qualifying Disagreement"), then Diller
                      shall be entitled to deliver notice of his election (a
                      "Management Election") to exercise his management rights
                      as a result of the occurrence of such Qualifying
                      Disagreement in the manner and to the extent set forth
                      below.

               (ii)   Following a Management Election by Diller: (A) Diller
                      shall be entitled to exercise his voting authority or
                      authority to act by written consent over all Silver
                      Securities then owned by each member of the Liberty
                      Stockholder Group and the Diller Stockholder Group on all
                      matters submitted to a vote of Silver stockholders, or by
                      which Silver stockholders may act by written consent,
                      pursuant to a conditional proxy (which proxy shall be

                      ceases to be the Chairman of the Board and/or Chief
                      Executive Officer and/or President of Silver or (y) such

                      Stockholder Group, to take or cause to be taken all
                      reasonable actions required (1) for the election of a
                      slate of directors of Silver, two of

                      whom will be designated by Liberty and the remainder of
                      whom will be designated by Diller, and (2) to prevent the
                      taking of any action by Silver or its subsidiaries with
                      respect to a Fundamental Matter without the consent of
                      both Stockholders; and (B) subject to applicable law and
                      fiduciary duties and except with respect to any
                      Fundamental Matters or a Class B Issuance, any matter
                      referred to in clause (x) or (y) of clause (i) above, and
                      except as otherwise specifically provided by this
                      Agreement, the August Agreement or the Silver Stockholder
                      Agreement, Liberty shall be required to use its reasonable
                      best efforts to cause its designees on the Silver Board of
                      Directors to vote with respect to any matter presented to
                      a vote of the Silver Board of Directors in the same manner
                      as Diller (or in the event that Diller is required to
                      abstain from voting under applicable law, in the same
                      manner as Diller's expressed preference), except to the
                      extent that such Liberty designees are required under
                      applicable law to abstain from voting.

               (iii)  Diller shall cease to be entitled to exercise any rights
                      under this Agreement, the August Agreement or the Silver
                      Stockholders Agreement with respect to the matters set
                      forth in this Section 3 upon the occurrence of any of the
                      following: (x) Diller is no longer Chairman of the Board
                      and/or Chief Executive Officer and/or President of Silver
                      and (y) the Diller Stockholder Group ceases to own its
                      Eligible Stockholder Amount of Silver Securities. Liberty
                      and Diller agree that, for purposes of determining
                      Liberty's Eligible Stockholder Amount the number of shares
                      of Silver Common Stock held by the Liberty Stockholder
                      Group shall be deemed to include that number of Silver
                      Securities then issuable to Liberty HSN pursuant to the
                      Contingent Right or to a member of the Liberty Stockholder
                      Group pursuant to the HSN Exchange Agreement, in addition
                      to the Liberty Stockholder Group's pro rata interest in
                      the Silver Securities held by Silver Company or a BDTV
                      Entity.

               (iv)   Each of Liberty and Diller agrees, and agrees to cause
                      each member of its Stockholder Group, to take all
                      reasonable actions required (including to vote or execute
                      a written consent with respect to the Silver Securities
                      held by Silver Company or any BDTV Entity) in order to
                      give effect to the provisions of this Section 3. In this
                      connection, (A) following the earlier to occur of the
                      events specified in clauses (x) and (y) of the
                      introductory paragraph of this Section 3, if so requested
                      by Liberty, all representatives of Diller and/or the
                      Diller Stockholder Group on the Silver Board of Directors
                      shall

                      immediately resign (other than the representative(s) to be
                      designated by Diller pursuant to clause (i) of this
                      Section 3) and (B) following a Management Election, if so
                      requested by Diller, all representatives of Liberty on the
                      Silver Board of Directors shall resign immediately (other
                      than two persons designated by Liberty).

               (v)    Notwithstanding the provisions of any Fundamental Matter
                      and except as otherwise provided herein, in the Merger
                      Agreement and the Exchange Agreement, each Stockholder
                      agrees, and agrees to cause each member of its Stockholder
                      Group, to take or cause to be taken all reasonable actions
                      required (including to vote or execute a written consent
                      with respect to the Silver Securities held by Silver
                      Company or a BDTV Entity) to prevent the taking by Silver
                      of any action with respect to any issuance or proposed
                      issuance of any shares of Silver Class B Common Stock (or
                      any rights or other securities exercisable or exchangeable
                      for, or convertible into, such shares), or the entering
                      into of any agreement, arrangement or understanding with
                      respect to any such issuance or proposed issuance, except
                      as specifically provided in this Agreement (such issuance,
                      a "Class B Issuance").

          4.   Fundamental Matters.  Upon the consummation of the Merger, the
               -------------------                                           
               indicated paragraphs of the definition of the term "Fundamental
               Matters" in the August Agreement shall be amended in their
               entirety to read as follows:

          6.   Termination of Merger Agreement and Exchange Agreement.  In
               ------------------------------------------------------

               applicable agreements, each of Liberty and Diller agrees to use,
               and to cause each of its respective officers, directors,
               employees, affiliates and representatives to use, all reasonable
               efforts and take all reasonable actions required or necessary to
               consummate the transactions contemplated by this Agreement, the
               August Agreement, the Merger Agreement and the Exchange
               Agreement, and to cause the conditions to each of the respective
               parties' obligations to consummate the foregoing transactions to
               be satisfied.

          8.   Liabilities under the Federal Securities Laws.  The exercise of
               ---------------------------------------------                  
               any rights hereunder or under the August Agreement or the Silver
               Stockholders Agreement by any member of the Diller Stockholder
               Group or the Liberty Stockholder Group (and including in the case

                                       15
<PAGE>
 
               Group, its exercise of rights relating to the Contingent Right
               and the Exchange Agreement) shall be subject to such reasonable
               delay as may be required to prevent the other Stockholder Group
               from incurring any liability under the federal securities laws
               and the parties agree to cooperate in good faith in respect
               thereof.

          9.   Miscellaneous.  This agreement shall be governed by and construed
               -------------                                                    
               in accordance with the laws of the State of New York applicable
               to agreements to be fully performed therein and without regard to
               principles of conflict of laws. This Agreement, together with the
               August Agreement, incorporates the entire understanding of the
               parties with respect to the subject matter herein and therein and
               supersedes all previous understandings, discussions, negotiations
               and agreements with respect to such subject matter. The August
               Agreement, as amended pursuant to the specific terms of this
               Agreement, is hereby ratified and confirmed in all respects;
               provided, however, (i) that in the event of any conflict between
               --------  -------                                               
               the terms of this Agreement and the terms of the August
               Agreement, the terms of this Agreement shall be deemed to
               supersede the conflicting terms of the August Agreement and (ii)
               for purposes of the computation of any time periods set forth in
               the August Agreement (including any applicable time periods
               relating to or based upon the execution of the Silver
               Stockholders Agreement), such time periods shall be deemed to
               have commenced on August 24, 1995. This Agreement may be executed
               in counterparts, each of which shall be deemed an original and
               all of which shall constitute one and the same instrument. Except
               as otherwise provided herein, neither party may assign this
               Agreement without the prior written consent of the other party.

               In the event of any conflicts between the provisions of this
               Agreement and the Merger Agreement (including the Exhibits
               thereto), the provisions of the Merger Agreement shall control.

               Whenever it is necessary for purposes of this Agreement to
               determine whether an exchange is tax-free or taxable, such
               determination shall be made without regard to any interest
               imputed pursuant to Section 483 of the Code.
