                        SECURITIES EXCHANGE ACT OF 1934

                                 IN RESPECT OF

                       UNITED VIDEO SATELLITE GROUP, INC.

INTRODUCTORY STATEMENT
- ----------------------

     This Statement relates to the Class A Common Stock, par value $.01 per
share (the "Class A Common Stock"), of United Video Satellite Group, Inc., a
Delaware corporation (the "Issuer" or "Company"), and includes information
regarding (i) the Class A Common Stock, and (ii) the Class B Common Stock, par
value $.01 per share (the "Class B Common Stock"), of the Company. Certain of
the Reporting Persons (as defined herein) have entered into the Letter Agreement
(as defined herein) with the Company and Tele-Communications, Inc. ("TCI"),
pursuant to which, among other things, TVG Holdings, Inc., one of the Reporting
Persons, will acquire from the Company newly-issued shares of Class A Common
Stock and Class B Common Stock, as reported herein, and, upon the acquisition of
such shares, certain of the Reporting Persons will enter into a stockholders
agreement with TCI and the Company (the "Stockholders Agreement").

     Section 7A of the Clayton Act, as added by Sections 201 and 202 of the 
Hart-Scott-Rodino Antitrust Improvement Act of 1976, requires, among other 
things, that persons intending to make certain acquisitions of voting securities
give to the Federal Trade Commission (the "FTC") and the Department of Justice
(the "DOJ") advance notification and wait a certain period (the "HSR Act Waiting
Period") before consummating such acquisitions. These notification and waiting
period requirements provide the FTC and DOJ with information about certain
transactions and with the opportunity to seek a preliminary injunction to
prevent consummation of transactions which may violate the antitrust laws. The
required notifications with respect to the transactions contemplated by the
Letter Agreement were made with the FTC and DOJ and, at midnight on August 1,
1998, the HSR Act Waiting Period expired, thus satisfying this material
condition to the consummation of such transactions pursuant to the Letter
Agreement. There are other material conditions to the consummation of such
transactions. Accordingly, the filing of this Statement shall not constitute an
admission that, as of the date hereof, any of the Reporting Persons has acquired
beneficial ownership of any voting securities of the Company.

     As a result of their agreement to enter into the Stockholders Agreement,
TCI and the Reporting Persons may constitute a "group" for purposes of Rule 13d-
5 under the Securities Act of 1934, as amended (the "Exchange Act"), with
respect to their respective beneficial ownership of the shares of Class A Common
Stock.  The filing of this Statement shall not constitute an admission that TCI
and the Reporting Persons constitute a "group" for purposes of Rule 13d-5
promulgated under the Exchange Act.

     The summary descriptions contained in this Statement 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.

     The share amounts and percentages reflected in this Statement do not give
effect to the Company's anticipated two-for-one stock split for holders of
record of the Class A and Class B Common Stock.

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

     The Company, NAI, TCI and News Corporation entered into an Agreement dated
June 10, 1998 (together with all Annexes and Schedules thereto, the "Letter
Agreement"). Pursuant to the Letter Agreement, subject to the conditions set
forth therein, NAI agreed, directly or through another direct or indirect
subsidiary of News Corporation, to: (A) sell to the Company (i) all of the
outstanding stock of News America Publications Inc. ("Publications") (which owns
and publishes TV Guide magazine and to which, prior to the closing of the
transactions contemplated under the Letter Agreement, NAI will cause the
transfer, as a contribution to capital, of the assets of the entertainment web
site known as TVGEN (which includes an electronic program guide) together with
rights to such intellectual property owned by NAI or any of its controlled
affiliates as are used in the conduct of the TVGEN business), and (ii) all of
the outstanding stock of TVSM, Inc. (together with Publications, the "NAI
Contributed Entities"), and (B) assign to the Company certain other rights (the
transactions described in clauses (A) and (B) are

                                       10

<PAGE>
 
collectively referred to herein as the "Transaction"), all upon the terms and
subject to the conditions set forth in the Letter Agreement, in exchange for
$800,000,000 in cash and 30,000,000 shares of the Company's common stock
(11,251,706 shares of Class A Common Stock and 18,748,294 shares of Class B
Common Stock, with the number of shares of Class A Common Stock relative to
Class B Common Stock being subject to adjustment as provided in the Letter
Agreement). The shares of Class A Common Stock and Class B Common Stock to be
issued by the Company in the Transaction will be issued to Holdings.

     Pursuant to the Letter Agreement, TCI has agreed to vote its shares of
Class A Common Stock and Class B Common Stock in favor of approval of the
Transaction at the meeting of the Company's stockholders to be held to obtain
such approval.  Further, the Company, TCI, NAI and News Corporation have agreed
to enter into (and to cause Holdings to enter into) the Stockholders Agreement,
as described in Annex A to the Letter Agreement, which shall become effective
upon the closing of the Transaction.  Additionally, except as set forth in the
Letter Agreement, TCI and News Corporation have agreed that, until the closing
of the Transaction, (i) the Company (in the case of TCI) and the NAI Contributed
Entities (in the case of News Corporation) will be the exclusive vehicles
through which TCI and News Corporation, directly or indirectly through their
subsidiaries or controlled affiliates, conduct guide businesses (print,
electronic or otherwise), whether within or outside the United States, and (ii)
neither TCI nor News Corporation shall, directly or indirectly through
subsidiaries or controlled affiliates, invest in or acquire any guide business
prior to the closing of the Transaction.  Each of TCI and News Corporation  has
also agreed, directly or through their respective subsidiaries, to purchase,
either through open market purchases or purchases of newly issued shares (which
the Company has agreed to sell), such additional shares of Class A Common Stock
as shall be necessary to equalize the number of shares held by each of them
after the closing of the Transaction and the closing or abandonment of certain
other transactions contemplated by the Company.

                                       11

<PAGE>
 
     The Reporting Persons expect that the Stockholders Agreement will provide
for, among other things, (i) TCI and Holdings each initially having the right to
designate four directors of the Company (in each case representing 40% of the
number of directors constituting the entire Board of Directors of the Company)
(the "Company Board"), with such eight director designees then selecting or
nominating two directors who must qualify as independent directors under the
rules of the Nasdaq Stock Market, subject to pro rata adjustment to reflect
sales or conversions of Class B Common Stock; (ii) except as set forth in the
Stockholders Agreement, the Company being the exclusive vehicle through which
the parties thereto, directly or indirectly through their respective
subsidiaries and controlled affiliates conduct guide business (print, electronic
or otherwise), whether within or outside the United States, so long as TCI, on
the one hand, and News Corporation, on the other hand, is entitled to designate
at least one director of the Company; (iii) certain transfer restrictions with
respect to the disposition by the parties thereto of shares of Class A Common
Stock and Class B Common Stock or the conversion of shares of Class B Common
Stock into shares of Class A Common Stock, subject to the terms and conditions
set forth in the Stockholders Agreement; (iv) voting restrictions imposed upon
the parties thereto requiring them to vote their shares of the Company's common
stock in a manner mutually agreed upon by TCI and Holdings or failing such
agreement against any proposal so long as each of TCI and Holdings continues to
own a sufficient number of shares of Class B Common Stock such that it is
entitled to designate at least one director; (v) the affirmative vote of at
least seven of the ten directors being required to approve any action of the
Company Board, except of the removal of the Chief Executive Officer of the
Company (the "CEO"), which will require approval of six of the ten directors;
and (vi) the establishment of an Executive Committee of the Company Board,
consisting of the CEO, the President of the Company and one representative of
each of TCI and Holdings, which committee shall take action, by the unanimous
vote or consent of all members of the Executive Committee, on behalf of the
Company Board, based upon the powers and duties delegated to it by the entire
Company Board.

                                       12

<PAGE>
 
     As a result of the voting power associated with the shares of the Class B
Common Stock and as the sole holder of Class B Common Stock, TCI may currently
be deemed to control the Company. Following the closing of the Transaction, TCI
and Holdings may be deemed to share control of the Company. However, neither TCI
nor Holdings will have the ability to affirmatively direct management of the
Company of the Company's corporate transactions without the concurrence of the
other. The foregoing description in this Item 4 of the rights and obligations of
the parties to the Letter Agreement and the Stockholder Agreement is qualified
in its entirety by the terms and conditions of the Letter Agreement, which is
hereby incorporated herein by reference.

     Other than as described herein, none of the Reporting Persons have any
present plans or proposals which relate to or would result in: (a) the
acquisition by any person of additional securities of the Company or the
disposition of securities of the Company; (b) an extraordinary corporate
transaction, such as a merger, reorganization or liquidation, involving the
Company or any of its subsidiaries; (c) a sale or transfer of a material amount
of assets of the Company or any of its subsidiaries; (d) any change in the Board
of Directors or management of the Company, including any plans or proposals to
change the number or terms of directors or to fill any existing vacancies on the
Board of Directors of the Company; (e) any material change in the present
capitalization or dividend policy of the Company; (f) any other material change
in the Company's business or corporate structure; (g) changes in the Company's
charter, by-laws or instruments corresponding thereto or other actions which may
impede the acquisition of control of the Company by any person; (h) a class of
securities of the Company being delisted from a national securities exchange or
ceasing to be authorized to be quoted in an inter-dealer quotation system of a
registered national securities association; (i) a class of equity securities of
the Company becoming eligible for termination of registration pursuant to
Section 12(g)(4) of the Exchange Act; or (j) any action similar to those
enumerated above.

     Notwithstanding anything contained herein, each of the Reporting Persons
reserves the right, depending on all relevant factors, to change its intention
with respect to any and all of the matters referred to in the preceding
paragraph.

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

     Upon the consummation of the Transaction, Holdings will be the direct
beneficial owner of 11,251,706 shares of Class A Common Stock and 18,748,294
shares of Class B Common Stock, and each of News Corporation, NPAL, NAI and Mr.
Murdoch, as persons who may be deemed to control Holdings, may also be deemed to
beneficially own such shares. Based upon the number of shares reflected as
outstanding as of June 19, 1998 in the Company's definitive proxy statement on
Schedule 14A for the Company's 1998 annual meeting, and after giving effect to
the Transaction and assuming that the Company issues 6,375,000 additional shares
of Class B Common Stock to TCI and/or its affiliates upon consummation of the
"Netlink Transaction" as defined in the Letter Agreement and described in TCI's
Statement on Schedule 13D, as amended, the shares of the Company's securities
beneficially owned by the Reporting Persons will represent approximately 31.6%
of the Class A Common Stock (approximately 41% assuming the conversion of the
Reporting Persons' Class B Common Stock into Class A Common Stock), 50% of the
Class B Common Stock, and approximately 48.4% of the combined voting power of
the Class A Common Stock and the Class B Common Stock voting together as a
single class. Each share of Class A Common Stock has one vote, and each share of
Class B Common Stock has ten votes, on all matters presented to the holders of
such shares. The Class A Common Stock and Class B Common Stock vote together as
a single class for the election of directors and on all other matters to be
voted on by the stockholders of the Company, except as required by law.

     Except as described above, no transactions were effected by the Reporting
Persons in the Common Stock during the 60 days preceding the date hereof.

outstanding  stock of News America Publications Inc. ("Publications") (which

"Closing"), NAI will cause the transfer, as a contribution to capital, of the
assets of NAI's entertainment web site known as TVGEN (which includes an

owned by NAI or any of its controlled affiliates as is used in the conduct of
the TVGEN business (such assets and rights, "TVGEN")) and (ii) all of the
outstanding stock of TVSM, Inc. ("TVSM" and, together with Publications,
 the

UVSG any unexpired rights NAI or any of its affiliates may have (e.g.,
indemnification, post-closing tax covenants, access rights, further assurances,
etc.) under agreements pursuant to which it acquired or (in the case of TVSM)
expects to acquire any NAI Contributed Entity or any material portion of any NAI
Contributed Entity's business or assets (collectively, the "Transaction"), all
upon the terms and subject to the conditions set forth herein and in the Annexes
hereto and such additional terms and conditions as may be agreed upon by the
parties hereto.  Provided that the effect thereof would not be adverse to TCI or
UVSG in any material respect (determined without regard to any other materiality
provision hereof), NAI may transfer the NAI Contributed Entities to a direct or
indirect subsidiary of News Corp. incorporated in the United States prior to the
Closing.  In the event of such transfer, such entity shall make the same

The parties hereto will cooperate with each other to the fullest extent
reasonably practicable in the preparation of the Definitive Agreements and all
related documents, in the obtaining of all necessary consents and in complying
with all regulatory requirements.  Although the parties intend to diligently
negotiate and promptly enter into the Definitive Agreements, the parties
acknowledge and agree that this Agreement is a binding agreement, subject in any
event to the terms and conditions hereof.

be kept in strict confidence.  If this Agreement is terminated for any reason,
such information and all such documentation with respect thereto and all copies
thereof shall be destroyed or returned and all notes, memoranda or other similar

                ANNEX B - REPRESENTATIONS AND WARRANTIES OF NAI

     As used in this Agreement, (i) the term "NAI Contributed Entities" means
Publications and TVSM, together with each of their respective subsidiaries (and
TVGEN, which shall be deemed to be owned by Publications) and (ii) the term "NAI
Contributed Businesses" means the businesses conducted by the NAI Contributed
Entities (which constitute all businesses conducted by NAI and its controlled
affiliates engaged in the print or electronic program guide business other than
the NDS Business).  All references to NAI and its affiliates or controlled
affiliates shall be deemed to include a reference to the NAI Contributed
Entities.

     Notwithstanding the foregoing and the following representations and
warranties, no representation or warranty is made by NAI hereunder with respect
to TVSM unless and until NAI's proposed acquisition of TVSM is consummated,
except that NAI has furnished to UVSG a true and complete copy of the most
recent draft Merger Agreement dated June 7, 1998, together with the draft
schedules thereto, in the most recent form delivered to NAI by TVSM.
Representations and warranties of NAI with respect to TVSM following the
consummation of NAI's proposed acquisition of TVSM shall relate solely to facts
and circumstances which arise after the consummation of NAI's proposed
acquisition of TVSM.

     The representations and warranties set forth in this Annex B are made
subject to

     1.   Organization.  Each of NAI and the NAI Contributed Entities is a
          ------------                                                    
corporation duly organized, validly existing and in good standing under the laws
of its jurisdiction of incorporation and has all requisite corporate power and
authority and all necessary licenses and permits to carry on its business as it
has been and is now being conducted and to own or lease and to operate the
properties used in connection therewith.  Each of NAI and the NAI Contributed
Entities is duly qualified or licensed and in good standing to do business in
each of the jurisdictions where the conduct of its business or the ownership,
leasing or operation of its properties requires such qualification or licensing,
except where the failure to be so duly qualified or licensed and in good
standing, individually or in the aggregate, would not have a material adverse
effect on the business, operations, properties or condition (financial or
otherwise) of any of the NAI Contributed Entities or any of the NAI Contributed
Businesses or the ability of NAI to consummate the transactions contemplated
herein (collectively, a "Publications Material Adverse Effect").

     2.   Capitalization; Options and Other Rights.  The total authorized

issued and outstanding are set forth in the NAI  Disclosure Schedule.  All of
the issued and outstanding shares of capital stock of the NAI Contributed
Entities have been duly and validly authorized and issued and are fully paid and
nonassessable, and are held of record and beneficially by NAI or by a direct or
indirect wholly owned U.S. subsidiary of NAI (or, subject to compliance with the
terms and conditions of this Agreement, a U.S. direct or indirect subsidiary of
News Corp.) free and clear of any Liens (as hereinafter defined)

                                      -25-

and Restrictions (as hereinafter defined), with the sole right to vote, dispose
of, and receive dividends or distributions with respect to such shares.  There
are no existing agreements, subscriptions, options, warrants, calls,
commitments, trusts (voting or otherwise), or rights of any kind whatsoever
granting to any Person (as hereinafter defined) any interest in or the right to
purchase or otherwise acquire, at any time, or upon the happening of any stated
event, any capital stock of the NAI Contributed Entities, whether or not
presently issued or outstanding, nor are there any outstanding securities of the
NAI Contributed Entities or any other entity which are convertible into or
exchangeable for shares of capital stock of the NAI Contributed Entities, nor
are there any agreements, subscriptions, options, warrants, calls, commitments
or rights of any kind whatsoever granting to any person any interest in or the
right to purchase or otherwise acquire from NAI or any of its affiliates or any
other entity any securities so exercisable convertible or exchangeable, nor are
there any proxies, agreements or understandings with respect to the voting of
such shares.  Upon consummation of the Transaction, UVSG will hold, directly or
indirectly, of record and beneficially all of the outstanding shares of capital
stock of each of the NAI Contributed Entities free and clear of any Liens and
Restrictions, with the sole right to vote, dispose of, and receive dividends or
distributions with respect to such shares. In this Agreement, any reference to
"Restrictions," with respect to any capital stock, partnership interest,
membership interest in a limited liability company or other security, shall mean
any voting or other trust or agreement, option, warrant,  preemptive right,
right of first offer, right of first refusal, escrow arrangement, proxy, buy-
sell agreement, power of attorney or other contract, any law, rule, regulation,
order, judgment or decree which, conditionally or unconditionally, (i) grants to
any Person the right to purchase or otherwise acquire, or obligates any Person
to sell or otherwise dispose of or issue, or otherwise results or, whether upon
the occurrence of any event or with notice or lapse of time or both or
otherwise, may result in any person acquiring, (A) any of such capital stock or
other security; (B) any of the proceeds of, or any distributions paid or which
are or may become payable with respect to, any of such capital stock or other
security; or (C) any interest in such capital stock or other security or any
such proceeds or distributions; (ii) restricts or, whether upon the occurrence
of any event or with notice or lapse of time or both or otherwise, is reasonably
likely to restrict the transfer or voting of, or the exercise of any rights or
the enjoyment of any benefits arising by reason of ownership of, any such
capital stock or other security or any such proceeds or distributions; or (iii)
creates or, whether upon the occurrence of any event or with notice or lapse of
time or both or otherwise, is reasonably likely to create a Lien or purported
Lien affecting such capital stock or other security, proceeds or distributions.
Notwithstanding anything to the contrary contained in these representations and
warranties, the parties acknowledge that the existing stockholders of TVSM as of
the date hereof may have statutory rights of appraisal as a result of NAI's
acquisition of TVSM.

against NAI and/or its applicable affiliates in accordance with their respective
terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium
and similar laws affecting creditors' rights and remedies generally, and

whether enforcement is sought in a proceeding at law or in equity).

          (b) The execution and delivery of this Agreement and the other NAI
Transaction Documents by NAI and/or its applicable affiliates do not, and the
performance by NAI and/or its applicable affiliates of its obligations hereunder

or articles of incorporation or by-laws of NAI and/or its affiliates or any
amendments thereto or restatements thereof, (ii) violate any of the terms,
conditions or provisions of any law, rule or regulation applicable to NAI or its
affiliates or any order, writ, injunction, judgment or decree of any
Governmental Authority (as hereinafter defined) to which any of NAI or its

assets are bound, or (iii) result in a violation or breach of, or constitute
(with or without due notice or lapse of time or both) a default (or give rise to
any right of termination, cancellation or acceleration) under, or result in the
creation of any mortgage, pledge, lien, encumbrance, charge, or other security
interest (a "Lien") on any of the properties or assets of NAI or its affiliates
pursuant to, or require any consent by or approval or authorization of (a
"Contract Consent") any party under, any of the terms, conditions or provisions

venture agreement, or other agreement, instrument or obligation, oral or
written, to which NAI or any of its affiliates is a party (whether as an
original party or as an assignee or successor) or by which NAI or any of its
affiliates or any of their respective properties is bound, except for such
breaches or defaults as are not reasonably likely to have a Publications
Material Adverse Effect.

franchise, consent or permit (collectively, "Permits"), and no registration,
declaration or filing (collectively, "Filings") with any court, governmental
department, commission, authority, board, bureau, agency or other

Company and the consummation of the transactions contemplated hereby by the
Company, except the requirements under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976 (the "HSR Act"), and except where the failure to obtain
such Permits or to make such Filings is not reasonably likely to have a
Publications Material Adverse Effect.

          (d) There are no consents, authorizations or other approvals from or
notices to any Person other than a Governmental Authority (including, without
limitation, any Person that has entered into any contract, agreement,

other interest in, or any equity or similar interest or other right convertible
into or exercisable or exchangeable for or control of, any individual,

beneficially own all rights, title and interest that NAI or its affiliates have
or had in the EPG joint venture (a/k/a "TV Guide On-Screen") with an affiliate
of TCI.  Except as set forth in the NAI Disclosure Schedule, each interest in
any other Person owned by an NAI Contributed Entity is owned by the applicable
entity free and clear of any Liens and Restrictions, and each such Person is

used in connection therewith.

     5.   Charter and Organizational Documents.  NAI has furnished UVSG with

interest or amortization of goodwill (none of which will represent any actual or
contingent liability or commitment of the NAI Contributed Entities at Closing).
Each of the financial statements contained in the Unaudited Contributed

statements of the NAI Contributed Businesses that will be included in the proxy

respect under any contract, agreement, lease, undertaking, commitment or other

assignee or successor) as of the date hereof.

Businesses Financial Statements and except for liabilities or obligations that
fall within any of the exceptions contained in any of the other representations
or warranties contained in this Annex B (e.g., knowledge, materiality and
disclosed liabilities) or that arose in the ordinary course of business after
March 31, 1998 (and which have not resulted and are not reasonably likely to
result in a Publications Material Adverse Change), no NAI Contributed Entity has
any actual or potential liability or obligation of any kind or nature, whether
due or to become due, whether absolute, accrued, fixed or contingent or
otherwise. TVGEN has no liabilities or other obligations of any nature (other
than current liabilities incurred in the ordinary course of business and
obligations under executory contracts which have been made available to UVSG).

the NAI Contributed Businesses, nor any of their respective assets, properties

Material Adverse Effect.

          (b) None of NAI or any of its affiliates is a party to any Legal
Proceedings pending or, to its knowledge, threatened which, if adversely
determined, would adversely affect or restrict the ability of NAI or its
affiliates to consummate the transactions contemplated by this Agreement or to
perform its obligations hereunder.

          (c) There is no judgment, order, injunction or decree of any
Governmental Authority to which NAI or any of its affiliates is subject which

          -----------------------------------                                  
nor is there any judgment, injunction, order or decree, binding upon NAI or any
of its affiliates which has or could have the effect of prohibiting or
materially impairing any current business practice of any of the NAI Contributed
Businesses or the conduct of business by any NAI Contributed Entity as currently
conducted (including following the consummation of the transactions contemplated
by this Agreement).

     12.  Compliance with Law.  NAI and its affiliates (i) are in compliance
          -------------------                                               
with all federal, state, local or foreign laws (including common law), statutes,
codes, ordinances, rules, regulations or other requirements applicable to the
NAI Contributed Businesses or the NAI Contributed Entities or to the conduct of
the business or operations of the NAI Contributed Businesses or the NAI
Contributed Entities or the use of their respective properties (including any
leased properties) and assets and (ii) have all governmental permits and
approvals from Governmental Authorities which are required by the NAI
Contributed Businesses or the NAI Contributed Entities to operate their
respective businesses, except in such cases where the failure to comply or
obtain is not reasonably likely to have a Publications Material Adverse Effect.

     13.  Taxes.  Except as otherwise set forth in the NAI Disclosure Schedule:
          -----                                                                

          (a) Each of the NAI Contributed Entities has filed all material Tax
Returns that it was required to file.  All such Tax Returns are correct and
complete in all material respects. All material Taxes owed by any of the NAI
Contributed Entities (whether or not shown on any Tax Return) have been paid.
There are no liens for material Taxes (other than for current Taxes not yet due
and payable or for items being contested in good faith and for which there are
adequate reserves in accordance with GAAP on the books of the applicable entity)
on any of the assets of any of the NAI Contributed Entities.

<PAGE>
 
          (b) Each of the NAI Contributed Entities has withheld and paid all
material Taxes required to have been withheld and paid in connection with
amounts paid or owing to any employee, independent contractor or other third

asserted or assessed against the NAI Contributed Entities that are not
adequately reserved for in accordance with GAAP in all cases applied in a
consistent basis with the NAI Latest Balance Sheet.  The NAI Disclosure Schedule
indicates the Tax Returns of the NAI Contributed Entities that currently are the
subject of an audit.

          (d) None of the NAI Contributed Entities has any current non-
contingent liability for the Taxes of any Person (other than any of the NAI
Contributed Entities) under Treasury Regulations Section 1.1502-6 (or any
similar provision of state, local, or foreign law), as a transferee or
successor, by contract, or otherwise.

          (e) If the income of the NAI Contributed Entities is required under
federal, state, local or foreign tax rules, to be included on a consolidated,
unitary, combined or other such Tax Return which includes NAI or any of its
affiliates filed by an entity other than any of the NAI Contributed Entities,
each such group has filed all Tax Returns that it was required to file with
respect to NAI Contributed Entities for each period during which NAI Contributed
Entities was a member of such Group.  All such Tax Returns were correct and
complete in all material respects in so far as they relate to NAI  Contributed
Entities.  All material Taxes owed by such group with respect to NAI Contributed
Entities (whether or not shown on a Tax Return) have been paid for each taxable
period during which any of the NAI Contributed Entities was a member of its
respective group.

          (f) The normal period within which to examine and/or assess Taxes on
the income of NAI  Contributed Entities has not been extended with respect to
any such entity by waiver of, or agreement to extend, the applicable statute of
limitations or otherwise.

     14.  Employee Benefit Plans.
          ---------------------- 

          (a) Except as set forth on the NAI Disclosure Schedule, the NAI
Contributed Entities do not maintain, contribute to, or have any liability to or
in connection with, nor, have the NAI Contributed Entities maintained,
contributed to, or had any liability to or in connection with any employee
pension benefit plan, fund or program (exclusive of benefits contained in
contracts disclosed pursuant to Section 18 hereof), as such term is defined in
Section 3(2) of the Employee Retirement Income Security Act of 1974, as amended
("ERISA"), specifically including any multiemployer plan, as defined in Section
3(37) of ERISA, regardless of whether such pension plan, fund or program (i) is
or is intended to be covered or qualified under the Code, ERISA or any other
applicable law, (ii) is or is intended to be funded or unfunded, or (iii) covers
any current or former employee of or independent contractor to the NAI
Contributed Entities (the "Pension Plans").  The NAI Contributed Entities have
not, within the past six years, contributed to, maintained or been obligated to
contribute to such a multiemployer plan.

          (b) The NAI Disclosure Schedule contains a list (exclusive of benefits
contained in contracts disclosed pursuant to Section 18 hereof) of all other
employee benefit plans, funds or programs as such term is defined in Section
3(3) of ERISA which it has maintained, contributed to, or in connection with
which it has or has had any liability, specifically including any multiemployer
plan, as defined in Section 3(37) of ERISA, regardless of whether such employee
benefit plan, fund or program (i) is or is intended to be covered or qualified
under the Code, ERISA or any other applicable law, (ii) is or is intended to be
funded or unfunded, or (iii) covers any current or former employee of or
independent contractor to the NAI Contributed Entities ("Benefit Plans").

          (c) The NAI Disclosure Schedule lists (exclusive of benefits contained
in contracts disclosed pursuant to Section 18 hereof), with respect to
Publications, (i)  any stock option, stock purchase, phantom stock, stock
appreciation right, supplemental retirement, severance, sabbatical, employee
relocation, cafeteria benefit (Section 125 of the Code) or dependent care
(Section 129 of the Code), life insurance or accident insurance plans, programs
or arrangements, (ii) all deferred compensation, bonus, pension, profit sharing,
savings  or incentive plans, programs or arrangements, (iii) other fringe or
employee benefit plans, programs or arrangements that apply to employees of the
NAI  Contributed Entities, in each case, that are currently maintained or
directly contributed to by the NAI Contributed Entities or have been maintained
or contributed to by the NAI Contributed Entities since January 1, 1993
(collectively, with the plans, funds and programs referred to in (a) and (b)
above the "Employee Plans").

          (d) NAI has furnished to UVSG a copy of each of the Employee Plans and
related plan documents (including trust documents, insurance policies or
contracts, employee booklets, summary plan descriptions and other authorizing
documents, and, to the extent still in its possession, any material employee
communications relating thereto) and has, with respect to each Employee Plan
that is subject to ERISA reporting requirements, provided copies of the Form
5500, including all schedules attached thereto and actuarial reports, if any,
filed for the last three plan years.  Any Employee Plan intended to be qualified
under Sections 401(a) or 501(c)(9) of the Code is in fact so qualified and
either there has been obtained from the Internal Revenue Service a favorable

                                      -33-

<PAGE>
 
determination letter as to its qualified status under applicable Code provisions
and subsequent legislation, or the time for applying to the Internal Revenue
Service for such a determination letter has not expired under applicable
Treasury Regulations.  NAI has also furnished UVSG with the most recent Internal
Revenue Service determination letter issued with respect to each such Employee
Plan (and nothing has occurred since the issuance of each such letter which
could reasonably be expected to cause the loss of the tax-qualified status of
any Employee Plan subject to Section 401(a) of the Code), and all prohibited
transaction exemptions (or requests for such exemptions), private letter
rulings, opinions, information letters or compliance statements issued with
respect to any Employee Plan by the Internal Revenue Service, the Department of
Labor or the Pension Benefit Guaranty Corporation.

          (e) In the case of any policies or binders of insurance that
constitute or are otherwise maintained in connection with an Employee Plan, to
NAI's knowledge (i) such policies and binders are valid and enforceable in
accordance with their terms in all respects, and are in full force and effect;
(ii) Publications is not in default in any respect with respect to any material
provisions contained in any such policy or binder and has not failed to give any
notice or present any claim under any such policy or binder in a due and timely
fashion; and (iii) Publications has not received any notice of cancellation or
non-renewal of any such policy or binder; except to the extent that a failure
with respect to any of the foregoing is not reasonably likely to have, in the
aggregate, a Publications Material Adverse Effect.

          (f) Except as set forth in the NAI Disclosure Schedule, and except to
the extent that any failure with respect to the following is not reasonably
likely to have, in the aggregate, a Publications Material Adverse Effect, no
Employee Plan exists which will result in the payment of money or any other
property or rights, or accelerate or provide any other rights or benefits, to
any current or former employee of NAI (or other current or former service
provider thereto) that would not have been required but for the transactions
provided for herein and Publications is not party to any plan, program,
arrangement or understanding that would result, separately or in the aggregate,
in the payment of any "excess parachute payment" within the meaning of Section
280G of the Code, and except as disclosed in the NAI Disclosure Schedule,
Publications does not maintain any Employee Plan or Pension Plan which provides
severance benefits to current or former employees or other services providers of
NAI .  Except as disclosed in the NAI Disclosure Schedule, no medical or life
insurance benefits are provided by any Employee Plan to any former employee or
independent contractor, except to the extent required by the Consolidated
Omnibus Reconciliation Act of 1985, as amended "COBRA"). Except as set forth in
the NAI Disclosure Schedule, the NAI Contributed Entities have no obligation to
contribute to retiree life, health and other benefits.  Except as set forth in
the NAI Disclosure Schedule, the NAI Contributed Entities do not and have not
been a party to any collective bargaining (or other similar) agreement with
respect to any employee of the NAI Contributed Entities, nor is any such
agreement presently being negotiated.

          (g) (i)  None of the Employee Plans promises or provides retiree
medical or other retiree welfare benefits to any Person other than liabilities
which have been assumed by NAI and with respect to which none of the NAI
Contributed Entities will have any liability after the Closing Date; (ii) there
has been no "prohibited transaction," as such term is defined in Section 406 of
ERISA and Section 4975 of the Code, with respect to any Employee Plan; (iii)
each Employee Plan has been administered in accordance with its terms and in
compliance with the requirements prescribed by any and all statutes, rules and
regulations (including ERISA and the Code), and the NAI Contributed Entities
have performed all obligations required to be performed by them under, are not
in any

                                      -34-

<PAGE>
 
respect in default under or violation of, and have no knowledge of any default
or violation by any other party; (iv) no NAI Contributed Entity is subject to
any liability or penalty under Sections 4976 through 4980 of the Code or Title I
of ERISA with respect to any of the Employee Plans; (v) all material
contributions required to be made by the NAI Contributed Entities to any
Employee Plan have been made on or before their due dates; (vi) with respect to
each Employee Plan, no "reportable event" within the meaning of Section 4043 of
ERISA (excluding any such event for which the 30-day notice requirement has been
waived under the regulations to Section 4043 of ERISA) nor any event described
in Section 4062, 4063 or 4041 of ERISA has occurred; and (vii) no Employee Plan
is covered by, and no NAI Contributed Entity has incurred or expects to incur
any liability under Title IV of ERISA or Section 412 of the Code, except, in the
case of any failure to comply with clauses (ii), (iii), (iv), (v), (vi) and/or
(vii) above, for such failures which are not reasonably likely to have, in the
aggregate, a Publications Material Adverse Effect.  With respect to each
Employee Plan subject to ERISA as either an employee pension plan within the
meaning of Section 3(2) of ERISA or an employee welfare benefit plan within the
meaning of Section 3(1) of ERISA, each NAI Contributed Entity has prepared in
good faith and timely filed all requisite governmental reports (which were true
and correct as of the date filed) and has properly and timely filed and
distributed or posted all notices and reports to employees required to be filed,
distributed or posted with respect to each such Employee Plan except where the
failure to timely file, distribute or post such documents would not, in the
aggregate, have a Publications Material Adverse Effect.  No suit, administrative
proceeding, action or other litigation has been brought, or to the knowledge of
NAI, is threatened, against or with respect to any such Employee Plan, including
any audit or inquiry by the Internal Revenue Service or United States Department
of Labor which is reasonably likely to have, in the aggregate, a Publications
Material Adverse Effect.  No NAI Contributed Entity is a party to, or has made
any contribution to or otherwise incurred any obligation under, any
"multiemployer plan" as defined in Section 3(37) of ERISA.

          (h) With respect to each Employee Plan, each NAI Contributed Entity
has complied with (i) the applicable health care continuation and notice
provisions of COBRA and the regulations thereunder and (ii) the applicable
requirements of the Family and Medical Leave Act of 1993 and the regulations
thereunder, except to the extent that such failure to comply is not reasonably
likely to have in the aggregate, a Publications Material Adverse Effect.

          (i) The execution and delivery of this Agreement and the consummation
of the transactions contemplated hereby will not (i) entitle any current or
former employee or other service provider or any director of any NAI Contributed
Entity to severance benefits or any other similar payment (including
unemployment compensation, golden parachute, bonus or otherwise), (ii) increase
any benefits otherwise payable or (iii) accelerate the time of payment or
vesting, or increase the amount of compensation due any such employee, service
provider or director except to the extent that any of the foregoing are not
reasonably likely to have, in the aggregate, a Publications Material Adverse
Effect.

          (j) There has been no amendment to, written interpretation or
announcement (whether or not written) by any NAI Contributed Entity relating to,
or change in participation or coverage under, any Employee Plan which would
materially increase the expense of maintaining such Employee Plan above the
level of expense incurred with respect to that Employee Plan for the most recent
fiscal year included in the NAI Contributed Businesses Financial Statements.

     15.  Contracts and Commitments.  The NAI Disclosure Schedule lists all
          -------------------------                                        
contracts to which any NAI Contributed Entity is a party or by which it or the
NAI Contributed Businesses or their respective assets are bound that are to be
performed in whole or in part after the date hereof and that would be required
to be filed with the Securities and Exchange Commission (the "Commission") as
"material contracts" pursuant to Item 601 of Regulation S-K under the Securities
Act of 1933, as amended (the "Securities Act") if such NAI Contributed Entity
was a registrant registered under Section 12(g) of the Exchange Act of 1934, as
amended (the "Exchange Act"). The NAI Disclosure Schedule also lists (a) all
agreements, bonds, notes, debentures or similar instruments evidencing (i)
indebtedness of any NAI Contributed Entity for borrowed money or for the
deferred purchase price of any material property or service (other than trade
accounts arising in the ordinary course of business), (ii) obligations of any
NAI Contributed Entity under capital leases, (iii) guaranties by any NAI
Contributed Entity of liabilities or obligations of others, and (iv) any Liens
on the assets of any NAI Contributed Entity, (b) agreements that limit the right
of any NAI Contributed Entity to compete in any line of business; (c) agreements
which, after giving effect to the transactions contemplated hereby, purport to
restrict or bind NAI or any of its subsidiaries, other than the NAI Contributed
Entities; (d) all agreements not in the ordinary course of business pursuant to
which there is any continuing liability or obligation, including without
limitation any indemnification obligation; (e) merger, acquisition and similar
agreements that have any surviving obligations not performed in full, including
without limitation, any indemnity obligation; (f) agreements with any affiliate
of such NAI Contributed Entity; (g) any agreements not terminable on less than
75 days notice without penalty and involving amounts in excess of $6,000,000
during the 1997 fiscal year, reasonably expected during 1998, or as projected
over the remainder of the stated fixed term of the applicable agreement; and (h)
any collective bargaining or similar agreements.  True and complete copies of
all agreements listed in the NAI Disclosure Schedule have been made available to
UVSG.  Each of the NAI Contributed Entities has fulfilled in all material
respects, or taken all actions necessary to enable it to fulfill in all material
respects when due, its obligations under each of such agreements to which it is
a party.  To the knowledge of NAI, all parties thereto other than the NAI
Contributed Entities have complied in all material respects with the provisions
thereof and no party is in breach or violation of, or in default (with or
without notice or lapse of time, or both) under such agreements which breach,
violation or default is reasonably likely to have a Publications Material
Adverse Effect.  No NAI Contributed Entity has received any notice of
termination, cancellation or acceleration of any such agreement.

     16.  Adequacy of Assets; Intangible Property.
          --------------------------------------- 

          (a) The businesses conducted by the NAI Contributed Entities include
all businesses engaged in by NAI and its affiliates relating to the print or
electronic program guide business whether within or outside the United States
other than the NDS Business (the "Program Guide Businesses"). The assets and
rights held by the NAI Contributed Entities include all of the assets and other
rights used or usable by NAI and its affiliates in the Program Guide Business
and the business of TVGEN and no other assets, rights, liabilities, claims or
other obligations.  The assets owned or leased by the NAI Contributed Entities
are suitable and adequate for the conduct of their respective businesses and the
NAI Contributed Businesses have good and, with respect to real property owned in
fee, marketable title to or valid leasehold or other contractual interests in
all such assets that are material to the NAI Contributed Businesses as a whole,
free and clear of all Liens other than Permitted Encumbrances.  For purposes of
this Agreement, "Permitted Encumbrances" means the following Liens: (i) Liens
for Taxes, assessments or other governmental charges or levies not at the time
delinquent or thereafter payable without penalty or being contested in good
faith by

                                      -36-

<PAGE>
 
appropriate proceedings and for which adequate reserves shall have been set
aside on the Unaudited NAI Contributed Businesses Financial Statements in
accordance with GAAP; and (ii) Liens of carriers, warehousemen, mechanics,
materialmen and landlords incurred in the ordinary course of business for sums
not overdue or being contested in good faith by appropriate proceedings and for
which adequate reserves in accordance with GAAP shall have been set aside on the
Unaudited NAI Contributed Businesses Financial Statements.

          (b) One or more of the NAI Contributed Entities owns, or is licensed
or otherwise possesses legally enforceable rights to use, all patents,
trademarks, trade names, service marks, copyrights, and trade secrets
(collectively, "Intellectual Property") that are used in the NAI Contributed
Businesses as currently conducted, except to the extent that the failure to have
such rights has not had and is not reasonably likely to have a Publications
Material Adverse Effect.  The Intellectual Property includes (i) all right,
title and interest to the name "TV Guide" in the United States, (ii) all right,
title and interest to the name "TV Guide" outside the United States, if any,
held by NAI and its affiliates, (iii) all related trademarks, service marks,
trade names or copyrights used in the conduct of the NAI Contributed Businesses
and (iv) all right, title and interest that NAI or any of its affiliates has in
any Intellectual Property of or arising out of the former EPG joint venture
formerly known as TV Guide On Screen with an affiliate of TCI.  Neither NAI nor
any of its affiliates has received notice of any claim of infringement of the
rights of others with respect to any patents, trademarks, service marks, trade
names or copyrights used or owned by the NAI Contributed Entities, the loss of
which is reasonably likely to have a Publications Material Adverse Effect.
Neither NAI nor any of its affiliates has any knowledge that any of the NAI
Contributed Entities is infringing upon or otherwise violating, or has infringed
upon or otherwise violated, the rights of any third party with respect to any
patent, trademark, trade name, service mark or copyright, except to the extent
that the foregoing is not reasonably likely to have a Publications Material
Adverse Effect.  No current or former employee of any NAI Contributed Entity is
or was a party to any confidentiality agreement and/or agreement not to compete
which restricts or forbids such employee's performance of any activity that such
employee was hired to perform, except to the extent that the foregoing is not
reasonably likely to have a Publications Material Adverse Effect.  No NAI
Contributed Entity is currently using or has in the past used without
appropriate authorization, any confidential information or trade secrets of any
third party, except to the extent that any of the foregoing is not reasonably
likely to have a Publications Material Adverse Effect.  Since January 1, 1995,
NAI has not received any notice alleging such conduct.

     17.  Licenses; Compliance with Regulatory Requirements.
          ------------------------------------------------- 

          (a) The NAI Contributed Entities hold all licenses, franchises,
ordinances, authorizations, permits, certificates, variances, exemptions,
concessions, leases, rights of way, easements, instruments, orders and
approvals, domestic or foreign ("Licenses") which are material to the ownership
of the assets that are material to the NAI Contributed Businesses (collectively,
the "Publications Licenses").  Each NAI Contributed Entity is in compliance
with, and has conducted its business so as to comply with, the terms of their
respective Publications Licenses and with all applicable laws, rules,
regulations, ordinances and codes, domestic or foreign, except where the failure
so to comply has not had and, insofar as reasonably can be foreseen, in the
future will not have, either individually or in the aggregate, a Publications
Material Adverse Effect.  Without limiting the generality of the foregoing, the
NAI Contributed Entities, (i) have all Permits of Governmental Authorities
required for the operation of the facilities being operated by the NAI
Contributed Entities or required in the conduct of the NAI Contributed
Businesses, and all such

                                      -37-

<PAGE>
 
Permits are identified on the NAI Disclosure Schedule, (ii) have duly and
currently filed all reports and other information required to be filed by any
Governmental Authority in connection with such Permits, and (iii) are not in
violation of any of such Permits, other than the lack of Permits, delays in
filing reports or possible violations which, in the aggregate, have not had and
are not reasonably likely to have a Publications Material Adverse Effect.

          (b) Except as set forth in the NAI Disclosure Schedule, the NAI
Contributed Entities have duly complied with, and the operation of its business,
equipment and other assets and the facilities owned or leased by any NAI
Contributed Entities are in compliance with, the provisions of all applicable
Environmental and Health Laws, except for non-compliance which is not reasonably
likely to have a Publications Material Adverse Effect.  For purposes of this
Agreement, the term "Environmental and Health Laws" means any federal, state or
local law, statute, rule or regulation or the common law relating to the
environment or occupational health and safety, including any statute, regulation
or order pertaining to (i) treatment, storage, disposal, generation and
transportation of pollutants, contaminants, chemicals, industrial, toxic or
hazardous substances, oil or petroleum products or solid or hazardous waste
(collectively, "Hazardous Substances"); (ii) air, water and noise pollution;
(iii) groundwater and surface water contamination; (iv) the release into the
environment of Hazardous Substances, including without limitation emissions,
discharges, injections, spills, escapes or dumping of pollutants, contaminants
or chemicals; (v) the protection of wild life, marine sanctuaries and wetlands,
including without limitation all endangered and threatened species; (vi) storage
tanks, vessels and containers containing Hazardous Substances; (vii) underground
storage tanks, abandoned, disposed or discarded barrels and other closed
receptacles containing Hazardous Substances; (viii) health and safety of
employees; and (ix) manufacture, processing, use, distribution, treatment,
storage, disposal, transportation or handling of Hazardous Substances.  As used
herein, the terms "release" and "environment" have the meanings set forth in the
Comprehensive Environmental Response, Compensation, and Liability Act of 1980,
as amended.  There are no investigations, administrative proceedings, judicial
actions, orders, claims or notices that are pending, anticipated or threatened
against any NAI Contributed Entities relating to any Environmental and Health
Laws. Neither NAI nor any of its affiliates has received a notice of or knows
any facts which constitute a violation by any NAI Contributed Entities of or
give rise to liability of any NAI Contributed Entities under any Environmental
and Health Laws that in either case would or would be reasonably likely to have
a Publications Material Adverse Effect.

          (c) The NAI Contributed Businesses and the NAI Contributed Entities do
not own, lease or operate any printing facilities or otherwise conduct any
printing activities (other than printing services provided by Persons other than
the NAI Contributed Entities using facilities and materials that are owned and
operated by Persons other than the NAI Contributed Entities).

     18.  Employee Matters.  The NAI Disclosure Schedule lists each employment,
          ----------------                                                     
consulting, agency or commission agreement to which any of the NAI  Contributed
Entities is a party which is not terminable without liability to the NAI
Contributed Entities upon 60 days' or less prior notice to the employee,
consultant or agent and involves compensation or remuneration of more than
$50,000 per annum.  True and complete copies of such agreements have been made
available to UVSG.  All of such contracts and arrangements are in full force and
effect, and neither the NAI Contributed Entities nor, to the knowledge of NAI,
any other party is in default under any of such contracts and agreements.  To
the knowledge of NAI, (i) there have been no claims of defaults and (ii) there
are no facts or conditions which if continued, or on notice, will result in a
default under these contracts or arrangements.  There is no pending or, to the
knowledge of NAI , threatened labor dispute, strike,

                                      -38-

<PAGE>
 
or work stoppage that could be expected to have a Publications Material Adverse
Effect.  Each of the NAI Contributed Entities is in compliance in all material
respects with all current applicable laws and regulations respecting employment,
discrimination in employment, terms and conditions of employment, wages, hours
and occupational safety and health and employment practices, and are not engaged
in any unfair labor practice. There are no pending claims against any NAI
Contributed Entities under any workers compensation plan or policy or for long
term disability.  To the knowledge of NAI, none of the employees of the NAI
Contributed Businesses are members of a labor union or similar labor
organization.

     19.  Interested Party Transactions.  The NAI Disclosure Schedule lists all
          -----------------------------                                        
transactions between any of the NAI Contributed Entities, on the one hand, and
NAI, News Corp., any of their respective subsidiaries or any director or
executive officer of any of the foregoing, on the other hand, in which the
amount involved exceeds $60,000 that would be required to be disclosed pursuant
to Item 404 of Regulation S-K under the Securities Act or the Exchange Act if
such NAI Contributed Entity was a registrant registered under Section 12(g) of
the Exchange Act.  No NAI Contributed Entity is indebted to NAI, News Corp., any
of their respective subsidiaries, or any director, officer, employee or agent of
any of the foregoing for borrowed money.

     20.  Insurance.  The NAI Contributed Entities, through one or more
          ---------                                                     
affiliates, have the benefit of policies of fire and casualty, liability and
other forms of insurance (including self insurance) in such amounts, with such
deductibles and against such risks and losses as are reasonable for the
operation of the businesses of the NAI Contributed Entities under the
circumstances in which they are being conducted.  All such policies are in full
force and effect, all premiums due and payable thereon as of the date hereof,
have been paid (other than retroactive or retrospective premium adjustments that
may be required to be paid with respect to any events or circumstances arising
prior to the Closing under any of such insurance policies, which, unless accrued
for in the Latest Balance Sheet, shall accrue to or be paid by NAI), and no
notice of cancellation or termination has been received with respect to any such
policy which policy has not been replaced prior to the date of such
cancellation.  To the knowledge of NAI, the activities and operations of the NAI
Contributed Entities have been conducted in a manner so as to conform in all
material respects to all applicable provisions of such insurance policies,
except for any failures so to conform that, individually or in the aggregate,
are not reasonably likely to have a Publications Material Adverse Effect.  The
coverage of such policies will cease upon the applicable Closing, but the NAI
Contributed Entities will continue to be entitled to the benefit of such
policies with respect to any covered event that occurs prior to the Closing
(including during any extended reporting period under "claims made" policies or
the like).

     21.  Major Advertisers and Suppliers.  The NAI Disclosure Schedule lists
          -------------------------------                                    
each advertiser of the NAI Contributed Entities that individually accounted for
more than one percent (1%) of the total dollar amount of revenues of the NAI
Contributed Businesses on a combined basis in 1997, showing the total dollar
amount of revenues for each such customer during each such year.  None of the
NAI Contributed Entities has received written notice from any customer in the
NAI Disclosure Schedule of such customer's intent not to remain a customer of
the NAI Contributed Entities after the Closing.  The NAI Disclosure Schedule
also lists each of the ten largest vendors to the NAI Contributed Businesses (by
dollar volume) during the most recently completed fiscal year.

     22.  Minute Books.  Except as set forth in the NAI Disclosure Schedule, NAI
          ------------                                                          
has made available to UVSG true and complete copies of the minute books of the
NAI Contributed Entities. Except as set forth in the NAI Disclosure Schedule,
such minute books contain summaries of all meetings of

                                      -39-

<PAGE>
 
directors and shareholders or actions by written consent since the later of (i)
January 1, 1995 and (ii) the time of the applicable entity's date of
incorporation, and such summaries are true and complete in all material respects
and reflect all transactions referred to in such minutes accurately in all
material respects.

     23.  Brokers' and Finders' Fees.  Neither NAI nor any of its controlled
          --------------------------                                        
affiliates has incurred, or will incur, directly or indirectly, any liability
for brokerage or finders' fees or agents' commissions or investment bankers'
fees or any similar charges in connection with this Agreement or any transaction
contemplated hereby.

     24.  Year 2000 Compliance.  NAI has conducted a preliminary assessment of
          --------------------                                                
the possible impact of Year 2000 Issues (as hereinafter defined) on the business
and operations of  Publications. NAI does not believe that the costs of required
modifications to existing programs of Publications and conversions to new
programs required in order to remediate any Year 2000 Issue are reasonably
likely to result in a Publications Material Adverse Effect.  For purposes of
this section, the term "Year 2000 Issues" means issues arising from the failure
or inability of any hardware, software or systems to correctly process, provide
and receive data within and between the years 1999 and 2000 and account for all
required leap year calculations for the year 2000.

     The representations and warranties set forth in this Annex C are made
subject to Schedule 1. Notwithstanding anything to the contrary contained in

duly qualified or licensed and in good standing to do business in each of the
jurisdictions where the conduct of its business or the ownership, leasing or
operation of its properties requires such qualification or licensing, except
where the failure to be so duly qualified or licensed and in good standing,
individually or in the aggregate, would not have a material adverse effect on
the business, operations, properties or condition (financial or otherwise) of
UVSG and its subsidiaries taken as a whole or the ability of UVSG to consummate
the transactions contemplated herein (a "UVSG Material Adverse Effect").

     2.   Capitalization; Options and Other Rights.

plan subsequent to December 31, 1997 that is approved by the stockholders of
UVSG, the grant subsequent to December 31, 1997 of options pursuant to such
plans or pursuant to the UVSG Stock Option Plans, and other than this Agreement
or shares of Class B Common Stock that may be converted to shares of Class A

subscriptions, options, warrants, calls, commitments, trusts (voting or
otherwise), or rights of any kind whatsoever to which UVSG is a party or by
which it is bound granting to any person any interest in or the right to
purchase or otherwise acquire from UVSG, at any time, or upon the happening of
any stated event, any capital stock of UVSG, whether or not presently issued or
outstanding, nor are there any outstanding securities of UVSG or any other
entity which are convertible into or exchangeable for shares of capital stock of
UVSG, nor are there any agreements, subscriptions, options, warrants, calls,

                                      -41-

obligations of UVSG, enforceable against it in accordance with their respective
terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium
and similar laws affecting creditors' rights and remedies generally, and
subject, as to enforceability, to general principles of equity (regardless of
whether enforcement is sought in a proceeding at law or in equity).

will not, (i) violate or conflict with any provision of the Certificate of
Incorporation or By-Laws of UVSG or any of its subsidiaries or any amendments
thereto or restatements thereof, (ii) violate any of the terms, conditions or
provisions of any law, rule or regulation applicable to UVSG or any of its

subsidiaries is subject or by which any of them or their respective assets are
bound, or (iii) result in a violation or breach of, or constitute (with or

connection with the execution, delivery and performance of this Agreement by
UVSG and the consummation of the transactions contemplated hereby by UVSG,

UVSG Material Adverse Effect.

Person (including, without limitation, any Person that has entered into any
contract, agreement, arrangement or understanding with UVSG or any of its

amendments thereto, filed by or on behalf of the NAI Contributed Entities (or

periods ending on or prior to the Closing Date, in each case, to the extent such
Tax Returns are reasonably relevant in the preparation by or on behalf of the
NAI Contributed Entities of Tax Returns subsequent to the Closing Date.

      2.  Termination of Prior Tax Settlement Agreements.  Except as otherwise
          ----------------------------------------------                      
provided in this letter agreement, all tax settlement and tax-sharing
agreements, arrangements, policies and guidelines, formal or informal, express
or implied, that may exist between the NAI Contributed Entities and any
affiliate ("Settlement Agreements") and all obligations thereunder shall
terminate prior to the Closing, and after the Closing Date, none of the NAI
Contributed Entities shall be bound by such Settlement Agreements or have any
liability thereunder.

     3.   Pre-Closing Taxes.
          ----------------- 

          (a) Each of the NAI Contributed Entities shall continue to be included
for all taxable periods (or portions thereof) ending on or before the Closing
Date in the consolidated Federal income Tax Return and any required state or
local consolidated or combined income or franchise Tax Returns of any affiliated
group of which any of them is a member (each of which is herein referred to as a

Entities (all such Tax Returns including taxable periods (or portions thereof)
of the NAI Contributed Entities ending on or before the Closing Date are
hereinafter referred to, collectively, as "Pre-Closing Consolidated Returns").
NAI shall cause its Selling Affiliated Groups to timely prepare and file (or
cause to be prepared and filed) all Pre-Closing Consolidated Returns and shall
timely pay all Taxes shown as due and payable on Pre-Closing Consolidated
Returns (including any Taxes with respect to any deferred income triggered into

Tax Returns of the NAI Contributed Entities which it formerly owned or
controlled, that are required by law for all taxable periods ending on or before
the Closing Date ("Pre-Closing Non-Consolidated Returns").  All Pre-Closing Non-

NAI Contributed Entities to pay as each may be liable) all Taxes due thereon.
NAI shall also pay (or cause the NAI Contributed Entities to pay as each may be
liable) the full amount of any Tax which is payable by the NAI Contributed
Entities without the filing of a Tax Return ("Non-

                                      -50-

<PAGE>
 
Return Taxes"), payment of which is due on or before the Closing Date.  With
respect to each Pre-Closing Non-Consolidated Return due after the Closing Date,
NAI shall deliver (or cause to be so delivered) each such Pre-Closing Non-
Consolidated Return to UVSG at least 15 days prior to the due date of such Tax
Return, together with a payment in an amount equal to the amount of Tax shown as
due and payable on such Pre-Closing Non-Consolidated Return (after giving effect
to any credits for the amount of Tax, if any, paid on or prior to the Closing
Date as shown on such Tax Return).  Subject to the foregoing, UVSG shall cause
the NAI Contributed Entities to file all such Pre-Closing Non-Consolidated
Returns that are due after the Closing Date and to pay the amount of Tax shown
as due and payable thereon (after giving effect to any credits for the amount of

similar taxes and fees arising out of or in connection with the transactions
contemplated by this Agreement shall be paid 50% by UVSG and 50% by NAI .

     5.   Post-Closing Taxes.  UVSG shall timely prepare and file (or cause to
          ------------------                                                  
be so prepared and filed) all Tax Returns required by law for all Taxes,
covering solely the NAI Contributed Entities, for taxable periods ending after
the Closing Date ("Post-Closing Returns").  UVSG shall timely pay or cause to be
paid all Taxes relating to Post-Closing Returns ("Post-Closing Taxes").  NAI
shall reimburse UVSG for (i) the amount of Post-Closing Taxes reported as
payable on each Post-Closing Return that is attributable to the portion of the
period covered by such Tax Return ending on the close of business on the Closing
Date (the "Pre-Closing Tax Period"), determined by treating the close of
business on the Closing Date as the last date of the taxable period, and (ii)
the amount of any Non-Return Tax payable after the Closing Date that is
attributable to the portion of the period covered by such payment which ends on
or before the close of business on the Closing Date (pro rata based upon the
number of days covered by such payment or if relevant as determined under clause
(i)), in each case after giving effect to any credits for the amount of such
Post-Closing Tax or such Non-Return Tax, if any, paid on or prior to the Closing
Date by NAI, the NAI Contributed Entities or any of their predecessors or
affiliates.  Such reimbursements shall be made on or before the later of the
date on which such return is filed or 15 days after receipt of a copy of such
return or evidence of such payment and UVSG shall provide NAI with copies of
workpapers which will permit NAI to review and substantiate the accuracy of such
return or such payment.

     6.   Tax Cooperation.  After the Closing Date, NAI shall submit (or cause
          ---------------                                                     
to be submitted) to UVSG blank Tax Return workpaper packages.  UVSG shall cause
the NAI Contributed Entities to prepare completely and accurately all
information that NAI shall reasonably request in such workpaper packages and
shall submit to NAI such packages within the later of 90 calendar days after
UVSG's receipt thereof or 90 calendar days after the close of the taxable period
to which a workpaper package relates.  The parties shall cooperate with each
other in connection with any Tax investigation, audit or other proceeding.  UVSG
shall preserve all information, returns, books, records and documents relating
to any liabilities for Taxes with respect to a taxable period until the later of
the expiration of all applicable statutes of limitation and extensions thereof,
or a final determination with respect to Taxes for such period.

     7.   Notification of Proceedings, Control; Refunds.
          --------------------------------------------- 

          (a) In the event that UVSG or any of the NAI Contributed Entities
receive notice, whether orally or in writing, of any pending or threatened
United States Federal, state, local, municipal or foreign tax examinations,
claims, settlements, proposed adjustments, assessments or reassessments or
related matters with respect to Taxes that could affect NAI or its Subsidiaries
(or the NAI Contributed Entities with respect to taxable periods or portions
thereof ending on or before the Closing Date), or if NAI or any of its
Subsidiaries receive notice of any such tax matter that could affect UVSG (or
any of the NAI Contributed Entities), the party receiving notice shall notify in
writing the potentially affected party within 10 calendar days thereof.  The
failure of any party to give the notice required by this Section 7.7(a) shall
not impair that party's rights under this Agreement except to the extent that
the other party demonstrates that it has been damaged thereby.

          (b) Each of NAI and UVSG shall have the right to control any audit or
examination by any taxing authority, initiate any claim for refund, file any
amended return, contest, resolve and defend against any assessment, notice of
deficiency or other adjustment or proposed adjustment relating or with respect
to any Taxes, the ultimate liability for which is the responsibility of that
party or its affiliates under this Agreement, and each of NAI  and UVSG shall be
entitled to, and to the extent received by the other shall be promptly paid by
the other, all refunds with respect to any such Taxes.  NAI  and UVSG shall
jointly control, defend and resolve any tax matter as to which they are both
liable (in whole or in part).

     8.   Indemnification.
          --------------- 

          (a) After the Closing Date, NAI shall indemnify and hold harmless
UVSG, the NAI Contributed Entities and each of their respective successors and
assigns from and against any Tax liability of the NAI Contributed Entities with
respect to the period ending on or before the Closing Date on any Pre-Closing
Non-Consolidated Return or on a Post-Closing Return (determined by treating the
Closing Date as the last date of the taxable period) and with respect to any
Non-Return Taxes attributable to the portion of the period covered by any
payment of such Taxes which ends on or before the Closing Date, in each case, to
the extent such amount exceeds (i) any amount previously paid to UVSG with
respect to such Tax pursuant to Section 1.3 or 1.5, as applicable, and (ii) the
$3,500,000 of reserves for such taxes on the Latest Balance Sheet.  NAI shall
pay such amounts as it is obligated to pay to UVSG within 10 calendar days after
payment of any applicable Tax liability by UVSG and to the extent not paid by
NAI within such 10-day period, the amount due shall thereafter include interest
thereon at a rate per annum equal to the prime rate as publicly announced from
time to time by The Bank of New York (the "Overpayment Rate"), adjusted as and
when changes to such Overpayment Rate shall occur, compounded semi-annually.
NAI shall indemnify and hold harmless UVSG, the NAI Contributed Entities and
each of their respective affiliates, successors and assigns, from and against
(i) any Tax liability for periods prior to and including the Closing Date
resulting from the NAI Contributed Entities being severally liable for any Taxes
of any consolidated group of which the NAI Contributed Entities are or were a
member pursuant to Treasury Regulations (S) 1.1502-6 or any analogous state or
local tax provision (including, without limitation, any Tax liability with
respect to any Pre-Closing Consolidated Return), and (ii) any Tax liability
resulting from the NAI Contributed Entities ceasing to be a member of any
Selling Affiliated Group filing consolidated or combined Tax Returns.

                                      -52-

<PAGE>
 
          (b) After the Closing Date, UVSG and each of the NAI Contributed
Entities, jointly and severally shall indemnify and hold harmless NAI and its
affiliates, successors and assigns from and against any Tax liability with
respect to the taxable period or portion thereof beginning after the Closing
Date. UVSG shall hold NAI harmless and be liable and pay for any and all Taxes
not incurred in the ordinary course of business attributable to the acts or
omissions of UVSG, its affiliates or the NAI Contributed Entities occurring
after the Closing but on the Closing Date other than acts specifically
contemplated by this document.  UVSG shall cause the appropriate NAI Contributed
Entity or Subsidiary of an NAI Contributed Entity to pay such amounts within 10
calendar days after payment of any such Tax liability by NAI and, to the extent
not paid by such NAI Contributed Entity or Subsidiary within such 10-day period,
the amount due shall thereafter include interest thereon at the Overpayment
Rate, compounded semi-annually.

          (c) To the extent permitted by law, the parties agree to treat
indemnity payments under this letter agreement as adjustments to the
consideration paid for the NAI Contributed Entities.
 
     9.   UVSG shall take any reasonable actions and cause Publications to take
any reasonable actions requested by NAI to permit NAI to elect to reattribute
losses of Publications pursuant to Treasury Regulations (S) 1.1502-20(g).
