"TINTA Common Stock") (other than any such shares held by TINTA in its treasury
or owned of record by TCI or any subsidiary of TCI, all of which will be
canceled), will be converted into the right to receive 0.58 of a share of Tele-
Communications, Inc. Series A Liberty Media Group Common Stock, $1.00 par value
per share (the "LMG Series A Stock"), subject to adjustment under certain
circumstances set forth in the Merger Agreement (as such ratio may be adjusted,
the "Exchange Ratio"). Other than the shares of TINTA Series B Stock held by
TCI, all of which will be canceled in the Merger, there are no outstanding
shares of TINTA Series B Stock.  The accompanying Proxy Statement/Prospectus
contains detailed information concerning the terms of the proposed Merger and
certain additional information.  Please give all of this information your
careful attention.  A copy of the Merger Agreement is included as Appendix I to
the accompanying Proxy Statement/Prospectus and should be read in its entirety.

     The Board of Directors of TINTA (the "TINTA Board") has carefully reviewed
and considered the terms and conditions of the proposed Merger.  In connection
with this review and consideration, the TINTA Board retained Salomon Brothers
Inc and Smith Barney Inc., collectively doing business as Salomon Smith Barney
("Salomon Smith Barney"), which delivered an oral opinion (which it subsequently
confirmed in writing) on August 21, 1998, to the TINTA Board, to the effect
that, as of the date thereof, the proposed Exchange Ratio was fair, from a
financial point of view, to the holders of TINTA Common Stock (other than TCI
and its subsidiaries).  A copy of Salomon Smith Barney's opinion, which sets
forth the matters considered and the scope of review undertaken in connection
therewith, is included as Appendix II to the accompanying Proxy
Statement/Prospectus.  The TINTA Board has determined that the terms of the
Merger are fair to, and in the best interests of, TINTA and its stockholders
other than TCI and its subsidiaries, has unanimously approved the Merger
Agreement and recommends that you vote FOR the proposal to adopt the Merger
Agreement.

     Adoption of the Merger Agreement at the Meeting requires the affirmative
vote of the majority in voting power of outstanding shares of TINTA Series A
Stock and TINTA Series B Stock entitled to vote thereon at the Meeting, voting
together as a single class.  As of October 2, 1998, TCI beneficially owned
shares of TINTA Common Stock with a combined voting power equal to approximately
[92%] of the voting power of the shares of TINTA Common Stock outstanding on
such date, and TCI has agreed in the Merger Agreement to cause all such shares
to be voted in favor of
<PAGE>
 
the adoption of the Merger Agreement. Such vote will assure that the Merger
Agreement will be adopted at the Meeting without regard to the votes cast by any
other stockholder of TINTA.

     Whether or not you are personally able to attend the Meeting, please
complete, sign and date the enclosed proxy card and return it in the enclosed
prepaid envelope as soon as possible.  This action will not limit your right to
vote in person if you wish to attend the Meeting and vote personally.  Any
signed proxies received by TINTA that are not specifically marked with a
direction of how to vote in connection with the Merger will be counted as
affirmative votes in favor of adoption of the Merger Agreement.


                              Sincerely yours,


 
                              John C. Malone

                   NOTICE OF SPECIAL MEETING OF STOCKHOLDERS
                        TO BE HELD ON NOVEMBER __, 1998

NOTICE IS HEREBY GIVEN that a special meeting of stockholders (together with any
adjournment or postponement thereof, the "Meeting") of Tele-Communications
International, Inc., a Delaware corporation ("TINTA"), will be held at TINTA's
corporate offices, 5619 DTC Parkway, Englewood, Colorado, on ___________,
November __, 1998, at 9:30 a.m., local time, for the following purposes:

          1.  To consider and vote upon a proposal to adopt an Agreement and
     Plan of Merger, dated as of August 24, 1998 (together with the exhibits and
     schedules thereto, the "Merger Agreement"), among Tele-Communications,
     Inc., a Delaware corporation ("TCI"), Liberty Group Acquisition Co., a
     Delaware corporation and a newly formed wholly-owned subsidiary of TCI
     ("Merger Sub"), and TINTA.  Pursuant to the Merger Agreement, (a) Merger
     Sub will be merged with and into TINTA, with TINTA as the surviving
     corporation (the "Merger") and, in connection therewith, (b) each share of
     Series A Common Stock, $1.00 par value per share, of TINTA ("TINTA Series A
     Stock") and each share of Series B Common Stock, $1.00 par value per share,
     of TINTA ("TINTA Series B Stock" and, together with the TINTA Series A
     Stock, "TINTA Common Stock") outstanding immediately prior to the Effective
     Time (as defined in the Merger Agreement) (other than any such shares held
     by TINTA in its treasury or owned of record by TCI or any subsidiary of
     TCI) will be converted into the right to receive 0.58 (the "exchange
     ratio") of a share of Tele-Communications, Inc. Series A Liberty Media
     Group Common Stock, $1.00 par value per share (the "LMG Series A Stock").
     Notwithstanding the foregoing, if the product of 0.58 and the LMG Market
     Price (as defined in the Merger Agreement) on the closing date of the
     Merger is less than $22.00, TCI must either (i) increase the exchange ratio
     to equal the quotient (rounded upwards, if necessary, to the nearest one
     one-thousandth) obtained by dividing $22.00 by such LMG Market Price or
     (ii) terminate the Merger Agreement.  Other than the shares of TINTA Series
     B Stock held by TCI, all of which will be canceled in the Merger, there are
     no outstanding shares of TINTA Series B Stock.  The terms of the Merger
     Agreement and the LMG Series A Stock are described in detail in the
     accompanying Proxy Statement/Prospectus, and the full text of the Merger
     Agreement (exclusive of exhibits and schedules) is included as Appendix I
     thereto.

          2.  To transact such other business as may properly come before the
     Meeting.

     The Board of Directors of TINTA has fixed the close of business on October
2, 1998 as the record date for the determination of stockholders entitled to
notice of, and to vote at, the Meeting.  Only holders of record of TINTA Common
Stock as of the close of business on such date are entitled to notice of, and to
vote at, the Meeting.  A list of TINTA stockholders entitled to vote at the
Meeting will be available for examination by any TINTA stockholder at the
Meeting and, for a period of ten business days prior to the date of the Meeting,
during ordinary business hours, at TINTA's corporate offices at 5619 DTC
Parkway, Englewood, Colorado 80111.

     The affirmative vote of the majority in voting power of outstanding shares
of TINTA Common Stock entitled to vote thereon at the Meeting, voting together
as a single class, is required to adopt the Merger Agreement.  As of the Record
Date, TCI beneficially owned approximately [83]% of the shares of TINTA Series A
Stock and 100% of the TINTA Series B Stock, representing approximately [92]% of
the combined voting power of the shares of TINTA Common Stock outstanding on
such date. In accordance with and subject to the terms of the Merger Agreement,
TCI has agreed to cause all such shares to be voted in favor of the proposal to
adopt the Merger Agreement.  Accordingly, it is expected that the Merger
Agreement will be adopted at the Meeting.  Holders of record of shares of TINTA
Common Stock as of the Record Date will not be entitled to any dissenters'
appraisal rights in connection with the Merger under Delaware law.

     To assure that your interests will be represented at the Meeting,
regardless of whether you plan to attend in person, please complete, sign and
date the enclosed proxy card and return it in the enclosed prepaid envelope as
soon as possible.  This action will not limit your right to vote in person if
you wish to attend the Meeting and vote personally.


                              By Order of the Board of Directors

 
                              Stephen M. Brett
                              Secretary

Englewood, Colorado
_______________, 1998

PLEASE EXECUTE AND RETURN THE ENCLOSED PROXY CARD PROMPTLY, WHETHER OR NOT YOU
INTEND TO BE PRESENT AT THE MEETING.  DO NOT SEND ANY STOCK CERTIFICATES WITH
THE ENCLOSED PROXY CARD.  THE PROCEDURE FOR THE EXCHANGE OF YOUR SHARES AFTER
THE MERGER IS CONSUMMATED IS SET FORTH IN THE ATTACHED PROXY STATEMENT/
PROSPECTUS.

For Special Meeting of Stockholders   Shares of Tele-Communications, Inc.      
to be held November __, 1998          Series A Liberty Media Group Common Stock 


                              ____________________


     This Proxy Statement/Prospectus is being furnished to holders of Series A
Common Stock, $1.00 par value per share ("TINTA Series A Stock"), and Series B
Common Stock, $1.00 par value per share ("TINTA Series B Stock" and, together
with the TINTA Series A Stock, "TINTA Common Stock"), of Tele-Communications
International, Inc., a Delaware corporation ("TINTA"), in connection with the
solicitation of proxies by the Board of Directors of TINTA (the "TINTA Board")
for use at a special meeting of stockholders of TINTA, or any adjournment or
postponement thereof (the "Meeting").  At the Meeting, holders of TINTA Common
Stock will consider and vote upon a proposal to adopt an Agreement and Plan of
Merger, dated as of August 24, 1998 (together with the exhibits and schedules
thereto, the "Merger Agreement"), among Tele-Communications, Inc., a Delaware
corporation ("TCI"), Liberty Group Acquisition Co., a Delaware corporation and a
newly formed wholly-owned subsidiary of TCI ("Merger Sub"), and TINTA.  Pursuant
to the Merger Agreement, Merger Sub will be merged with and into TINTA, with
TINTA as the surviving corporation (the "Merger").  As a result of the Merger,
stockholders of TINTA will become stockholders of TCI on the terms described in
this Proxy Statement/Prospectus.  See "THE MERGER AGREEMENT."

     On October 2, 1998, the record date for the Meeting (the "Record Date"),
TCI beneficially owned approximately [83]% of the shares of TINTA Series A Stock
and 100% of the shares of TINTA Series B Stock, which represent approximately
[92]% of the combined voting power of the shares of both series of TINTA Common
Stock entitled to vote at the Meeting.  The combined voting power of the shares
of TINTA Common Stock beneficially owned by TCI is sufficient to assure approval
at the Meeting of the proposal to adopt the Merger Agreement.  In accordance
with and subject to the terms of the Merger Agreement, TCI has agreed to cause
all such shares to be voted in favor of such proposal.

     SEE "RISK FACTORS" ON PAGE 13 FOR A DISCUSSION OF CERTAIN RISK FACTORS THAT
SHOULD BE CONSIDERED BY HOLDERS OF TINTA COMMON STOCK.

     This Proxy Statement/Prospectus and the accompanying form of proxy are
first being mailed to the stockholders of TINTA on or about ______________,
1998.


  THE SECURITIES TO BE ISSUED PURSUANT TO THIS PROXY STATEMENT/PROSPECTUS HAVE
        NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND EXCHANGE
           COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE
              COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED
                  UPON THE ACCURACY OR ADEQUACY OF THIS PROXY
                   STATEMENT/PROSPECTUS.  ANY REPRESENTATION
                     TO THE CONTRARY IS A CRIMINAL OFFENSE.


     The date of this Proxy Statement/Prospectus is _______________, 1998.

     Information contained herein is subject to completion or amendment. A 
registration statement relating to these securities has been filed with the 
Securities and Exchange Commission. These securities may not be sold nor may 
offers to buy be accepted prior to the time the registration statement becomes 
effective. This prospectus shall not constitute an offer to sell or the 
solicitation of an offer to buy nor shall there be any sale of these securities 
in any State in which such offer, solicitation or sale would be unlawful prior 
to registration or qualification under the securities laws of any State.
<PAGE>
 
     Upon consummation of the Merger, pursuant to the Merger Agreement, each
share of TINTA Common Stock outstanding immediately prior to the Effective Time
(other than any such shares held directly by TINTA in its treasury or owned of
record by TCI or any subsidiary of TCI, all of which will be canceled) will be
converted into the right to receive 0.58 of a share of Tele-Communications, Inc.
Series A Liberty Media Group Common Stock, $1.00 par value per share (the "LMG
Series A Stock").  Notwithstanding the foregoing, if the product of 0.58 and the
LMG Market Price (as hereinafter defined) on the closing date of the Merger is
less than $22.00, TCI must either (i) increase the exchange ratio to equal the
quotient (rounded upwards, if necessary, to the nearest one one-thousandth)
obtained by dividing $22.00 by such LMG Market Price or (ii) terminate the
Merger Agreement.  See "THE MERGER AGREEMENT-- Consideration to be Received in
the Merger."

     Holders of shares of TINTA Common Stock will not be entitled to any
dissenters' appraisal rights in connection with the Merger under Delaware law.
See "THE MERGER--Absence of Appraisal Rights."  Fractional shares of LMG Series
A Stock will not be issued in the Merger and holders of TINTA Common Stock
otherwise entitled to a fractional share of LMG Series A Stock will receive an
amount in cash equal to the same fraction of the current market value of a whole
share of LMG Series A Stock as determined in accordance with the Merger
Agreement.  See "THE MERGER AGREEMENT--Consideration to be Received in the
Merger."

     TCI has filed a registration statement on Form S-4 (together with all
amendments, exhibits and schedules thereto, the "Registration Statement") under
the Securities Act of 1933, as amended (the "Securities Act"), relating to the
shares of LMG Series A Stock that are proposed to be issued pursuant to or as
contemplated by the Merger Agreement.  This Proxy Statement/Prospectus also
constitutes the Prospectus of TCI filed as part of the Registration Statement.
All information contained in this Proxy Statement/Prospectus relating to TINTA
and its subsidiaries has been supplied by TINTA and all information relating to
TCI and its subsidiaries (other than TINTA and its subsidiaries) has been
supplied by TCI.

     TCI's common stock, $1.00 par value per share ("TCI Common Stock"), is
comprised of six series: (a) the Tele-Communications, Inc. TCI Group Series A
Common Stock ("TCI Group Series A Stock"), (b) the Tele-Communications, Inc. TCI
Group Series B Common Stock ("TCI Group Series B Stock" and, together with the
TCI Group Series A Stock, the "TCI Group Stock"), (c) the LMG Series A Stock,
(d) the Tele-Communications, Inc. Liberty Media Group Series B Common Stock
("LMG Series B Stock" and, together with the LMG Series A Stock, "LMG Stock"),
(e) the Tele-Communications, Inc. Series A TCI Ventures Group Common Stock (the
"TCIVG Series A Stock") and (f) the Tele-Communications, Inc. Series B TCI
Ventures Group Common Stock (the "TCIVG Series B Stock" and, together with the
TCIVG Series A Stock, the "TCIVG Stock").  Both series of the LMG Stock are
identical in all respects, except (i) each share of LMG Series B Stock has ten
votes and each share of LMG Series A Stock has one vote and (ii) each share of
LMG Series B Stock is convertible, at the option of its holder, into one share
of LMG Series A Stock.  Similarly, both series of the TCI Group Stock and both
series of the TCIVG Stock are identical in all respects, except (i) each share
of TCI Group Series B Stock and TCIVG Series B Stock has ten votes and each
share of TCI Group Series A Stock and TCIVG Series A Stock has one vote and (ii)
each share of TCI Group Series B Stock is convertible, at the option of its
holder, into one share of TCI Group Series A Stock and each share of TCIVG
Series B Stock is convertible, at the option of its holder, into one share of
TCIVG Series A Stock.  The shares of LMG Series A Stock, TCI Group Series A
Stock and TCIVG Series A Stock are not convertible.  See "DESCRIPTION OF TCI
CAPITAL STOCK--Common Stock."

     The TCI Group Stock is intended to reflect the separate performance of the
"TCI Group," which consists primarily of TCI's domestic cable television and
information distribution business, including the ownership and operation of
various cable television systems, as well as the TCI Group's minority interests
in various partnerships owning and operating cable television systems.  The LMG
Stock is intended to reflect the separate performance of the "Liberty Media
Group," which consists primarily of TCI's assets and businesses relating to
production, acquisition and distribution through all available formats and media
of branded entertainment, educational and informational programming and
software, including multimedia products, and electronic retailing, direct
marketing, advertising sales relating to programming services, infomercials and
transaction processing.  The TCIVG Stock is intended to reflect the separate
performance of the "TCI Ventures Group," which consists of TCI's entire 85%
equity interest in TINTA

                                      ii

                                       
<PAGE>
 
Common Stock and substantially all of TCI's non-cable and non-programming
domestic assets and businesses. The TCI Group, the Liberty Media Group and the
TCI Ventures Group are sometimes referred to herein individually as a "Group"
and collectively as the "Groups." See "DESCRIPTION OF TCI CAPITAL STOCK."

     On June 23, 1998, TCI entered into an Agreement and Plan of Restructuring
and Merger (together with the exhibits and schedules thereto, and as amended
from time to time, the "AT&T Agreement") among TCI, AT&T Corp. ("AT&T") and
Italy Merger Corp., which, subject to the terms and conditions thereof, provides
for the acquisition of TCI by AT&T.  Such acquisition will be effected through
the merger of Italy Merger Corp., a wholly-owned subsidiary of AT&T, with and
into TCI, with TCI as the surviving corporation (the "AT&T Merger").  As a
result of the AT&T Merger, TCI will become a wholly-owned subsidiary of AT&T,
and stockholders of TCI will become stockholders of AT&T.  See "THE AT&T MERGER
AND THE LIBERTY/VENTURES COMBINATION-- Consideration to be Received by Holders
of TCI Common Stock in the AT&T Merger."

     In a separate proposed transaction, TCI has announced its intention to
reclassify each share of TCIVG Series A Stock as 0.52 of a share of LMG Series A
Stock and each share of TCIVG Series B Stock as 0.52 of a share of LMG Series B
Stock, and in connection therewith, to combine the assets and businesses of the
Liberty Media Group and the TCI Ventures Group (the "Liberty/Ventures
Combination").  The Liberty/Ventures Combination is expected to occur prior to,
but is not conditional upon, the consummation of the AT&T Merger.  The combined
entity will be called the "Liberty Media Group" ("Liberty/Ventures Group") and
the LMG Stock will thereafter reflect the separate performance of the businesses
and assets attributed to the Liberty/Ventures Group.  Consummation of the
Liberty/Ventures Combination is subject to certain conditions, including
approval of the TCI stockholders.  Moreover, TCI has no contractual obligation
to effect the Liberty/Ventures Combination.  Accordingly, there can be no
assurance that the Liberty/Ventures Combination will be consummated.  See "THE
AT&T MERGER AND THE LIBERTY/VENTURES COMBINATION--The Liberty/Ventures
Combination."

     In the AT&T Merger, each share of LMG Series A Stock will be converted into
one share of a newly authorized class of common stock of AT&T which will be
intended to reflect the separate performance of the businesses and assets
attributed to the Liberty/Ventures Group.  Following the AT&T Merger, the
Liberty/Ventures Group will comprise the corporations, partnerships and other
entities and interests which, at the time of the AT&T Merger, comprise the
Liberty/Ventures Group or, if the Liberty/Ventures Combination has not occurred,
the Liberty Media Group and the TCI Ventures Group (except for certain assets
that the TCI Ventures Group will transfer to the TCI Group for cash prior to the
AT&T Merger, as contemplated by the AT&T Agreement).  AT&T will own 100% of the
businesses and assets attributed to the Liberty/Ventures Group but the day-to-
day management of the businesses of the Liberty/Ventures Group will continue to
be managed by certain members of TCI's management who currently manage the
businesses of the Liberty Media Group and the TCI Ventures Group and will remain
independent of AT&T management.  See "THE AT&T MERGER AND THE LIBERTY/VENTURES
COMBINATION."

     It is expected that the Merger will be consummated prior to the anticipated
closing date of the AT&T Merger. In such event and assuming the AT&T Merger is
consummated, shares of TINTA Common Stock that are converted into shares of LMG
Series A Stock in the Merger will ultimately be converted into the right to
receive shares of a newly authorized class of common stock of AT&T upon
consummation of the AT&T Merger in accordance with the AT&T Agreement.
Consummation of the Merger, however, is not contingent on the consummation of
the AT&T Merger or the other transactions contemplated by the AT&T Agreement,
and in the event such transactions are abandoned, former TINTA stockholders
would continue to own shares of LMG Series A Stock.   Consummation of the AT&T
Merger is subject to the separate approvals of the stockholders of AT&T and TCI,
receipt of all necessary governmental consents and approvals and other
conditions to closing set forth in the AT&T Agreement.  Accordingly, there can
be no assurance that the AT&T Merger will be consummated.  See "THE AT&T MERGER
AND THE LIBERTY/VENTURES COMBINATION."

Proxy Statement/Prospectus, the last reported sales prices on the National
Market tier of the Nasdaq Stock Market ("NASDAQ/NM") for shares of TINTA Series
A Stock and LMG Series A Stock were $____ and $____, respectively.

cast by, the other stockholders of TINTA, and accordingly it is expected that
the Merger Agreement will be adopted at the Meeting. No vote of the TCI
stockholders is required for adoption of the Merger Agreement. See "THE SPECIAL
MEETING."

THE MERGER

     Effect of the Merger.  Pursuant to the Merger Agreement, upon consummation
of the Merger, Merger Sub will merge with and into TINTA, with TINTA being the
surviving corporation (the "Surviving Corporation").  As a result of the Merger,
TINTA will become a wholly-owned subsidiary of TCI. The Merger will become
effective (the "Effective Time") on the date and at the time that a certificate
of merger relating to the Merger (the "Certificate of Merger") is accepted for
filing by the Secretary of State of the State of Delaware (the "Delaware
Secretary of State") in accordance with the applicable provisions of the DGCL
(or such later date and time as may be agreed to by TCI and TINTA and specified
in the Certificate of Merger).  Such filing is expected to take place as soon as
practicable after the closing of the transactions contemplated by the Merger
Agreement.  The date on which the closing of the transactions contemplated by
the Merger Agreement takes place, which, unless otherwise agreed among the
parties, shall be the date on which the last of the conditions precedent to the
Merger set forth in the Merger Agreement (other than the filing of the
Certificate of Merger and other than any such conditions which by their terms
are not capable of being satisfied prior to such date) is satisfied or, when
permissible, waived, is herein called the "Closing Date."  See "THE MERGER
AGREEMENT--General; Effective Time."

     Merger Consideration.  Pursuant to the Merger Agreement, at the Effective
Time, each share of TINTA Common Stock outstanding immediately prior to the
Effective Time (other than any such shares held by TINTA in its treasury or
owned of record by TCI or any subsidiary of TCI, all of which will be canceled)
will be converted into the right to receive 0.58 (the "exchange ratio") of a
share of LMG Series A Stock .  Notwithstanding the foregoing, if the product of
0.58 and the LMG Market Price (as defined below) on the Closing Date is less
than $22.00 (the "Minimum Value"), TCI must either (i) increase the exchange
ratio (the "Minimum Value Adjustment") to equal the quotient (rounded upwards,
if necessary, to the nearest one one-thousandth) obtained by dividing $22.00 by
such LMG Market Price or (ii) terminate the Merger Agreement.  The 0.58 exchange
ratio, or such exchange ratio as adjusted pursuant to the Merger Agreement, is
herein referred to as the "Exchange Ratio."  The LMG Series A Stock to be issued
in respect of a share of TINTA Common Stock pursuant to the Merger is herein
sometimes referred to as the "Merger Consideration."  "LMG Market Price" means
the average of the closing sales prices (or, if on any day no sale price is
reported, the average of the quoted high and low bid prices on such day) of a
share of LMG Series A Stock on the NASDAQ/NM (or, if the LMG Series A Stock is
not traded on the NASDAQ/NM, on the principal stock exchange on which such stock
is traded) on each of the five consecutive trading days immediately preceding
the trading day prior to the Closing Date.  Fractional shares of LMG Series A
Stock will not be issued in the Merger and holders of TINTA Common Stock
otherwise entitled to a fractional share of LMG Series A Stock will receive an
amount in cash equal to the same fraction of the current market value of a whole
share of LMG Series A Stock determined as described herein under "THE MERGER
AGREEMENT-- Consideration to be Received in the Merger."  For a summary of the
material differences between the rights of holders of LMG Series A Stock and the
rights of holders of TINTA Common Stock, see "COMPARISON OF STOCKHOLDERS'
RIGHTS."  For a description of the LMG Series A Stock to be issued in the
Merger, see "DESCRIPTION OF TCI CAPITAL STOCK--Common Stock."

     At the Effective Time, the 4 1/2% Convertible Subordinated Debentures due
2006 of TINTA (the "Debentures") outstanding immediately prior to the Effective
Time will remain outstanding and will remain obligations of TINTA as the
surviving corporation in the Merger.  As a result of the Merger, however, the
Debentures, which are currently convertible into shares of TINTA Series A Stock,
will become convertible into shares of LMG Series A Stock at an adjusted
conversion price.  In addition, as a result of and subsequent to the Merger,
holders of Debentures will have the right, in accordance with and subject to the
time periods prescribed by the terms of the Debentures, to require TINTA to
purchase any Debentures (or portion thereof) at a purchase price equal to 100%
of the principal amount tendered, plus accrued and unpaid interest thereon to
the purchase date.  See "THE MERGER--Certain Consequences of the Merger;
Operations Following the Merger."

     TINTA's Reasons for the Merger; Recommendation of the TINTA Board.  The
TINTA Board has unanimously approved the Merger Agreement, has determined that
it is advisable and fair and in the best interests of TINTA and its stockholders
other than TCI and its subsidiaries, and unanimously recommends that holders of
shares of TINTA Common Stock vote FOR the proposal to adopt the Merger
Agreement.  In reaching its decision to approve the Merger Agreement and to
recommend that TINTA's stockholders vote to adopt the Merger Agreement, the
TINTA Board considered the following factors: (i) the financial condition,
competitive position and prospects of each of TINTA and the Liberty Media Group,
and TINTA's future prospects as a stand-alone entity and on a combined basis
with the Liberty Media Group; (ii) the opinion of Salomon Smith Barney as to the
fairness, from a financial point of view, of the Exchange Ratio to the holders
of TINTA Common Stock (other than TCI and its subsidiaries); (iii) the terms of
the Merger Agreement, including that each share of TINTA Common Stock would be
exchanged in the Merger for a number of shares of LMG Series A Stock having a
value of at least $22.00 per share; (iv) the expected difficulties TINTA would
encounter in pursuing its growth strategy as a stand-alone company given its
leverage at the holding company level, the capital needs of its subsidiaries and
affiliates, its limited access to capital and its limited ability to access the
cash flow of its less than majority-owned subsidiaries and affiliates; (v) the
increased liquidity of the LMG Series A Stock compared to the TINTA Series A
Stock; and (vi) the ability of holders of TINTA Common Stock to continue to
participate in the growth of TINTA's international assets through their
ownership of LMG Series A Stock while limiting their exposure to the
uncertainties of a business whose subsidiaries and affiliates operate almost
exclusively outside the United States.  The TINTA Board also considered that the
holders of TINTA Common Stock would have an opportunity to participate in the
future performance of the other businesses and assets of the Liberty Media Group
through their ownership of LMG Series A Stock, which they would receive through
a tax-free exchange in the Merger.  See "THE MERGER--TINTA's Reasons for the
Merger; Recommendation of the TINTA Board" and "--Fairness Opinion."  For a
discussion of the interests of certain members of the TINTA Board in the Merger,
see "THE MERGER--Interests of Certain Persons in the Merger."

     TCI's Reasons for the Merger.  TCI believes that the acquisition of the
outstanding equity interests in TINTA not already owned by TCI will benefit TCI
and its stockholders.  In reaching its decision to make the merger proposal and
to enter into the Merger Agreement, TCI considered its management's assessment
of TINTA's existing financial position, the market performance of the TINTA
Series A Stock since its initial public offering in July 1995, industry and
market conditions, and the following factors: (i) that the combination of
TINTA's programming and distribution assets and the Liberty Media Group's
programming interests would result in substantial synergies; (ii) that as a
wholly-owned subsidiary of TCI, TINTA would benefit from TCI's greater liquidity
and access to capital, thereby increasing TINTA's ability to satisfy the capital
requirements necessary for it to pursue its growth strategy; (iii) that
operating costs could be reduced through more efficient use of shared personnel
and the elimination of duplicate public company costs; and (iv) that certain
potential conflicts of interests between TINTA and the Liberty Media Group
relating to the growth of their respective programming businesses would be
eliminated.  See "THE MERGER--TCI's Reasons for the Merger."

     Conditions to the Merger.  The respective obligations of TINTA and TCI to
consummate the transactions contemplated by the Merger Agreement are subject to
the satisfaction or, where permissible, waiver of a number of conditions,
including (a) adoption of the Merger Agreement by the requisite vote of
stockholders of TINTA; (b) absence of any effective injunction or similar order
preventing consummation of the transactions contemplated by the Merger Agreement
as provided therein; (c) receipt of certain opinions of legal counsel, including
the opinions of Baker & Botts, L.L.P. ("Baker & Botts") and Sherman & Howard
L.L.C. ("Sherman & Howard") described elsewhere in this Proxy
Statement/Prospectus to the effect that the Merger will qualify as a tax-free
reorganization for federal income tax purposes; and (d) certain other conditions
that are usual and customary conditions for merger transactions.  See "THE
MERGER AGREEMENT--Conditions to the Merger."

     Covenants.  Under the Merger Agreement, TINTA has agreed, prior to the
Effective Time, to conduct its business in the ordinary and usual course
consistent with past practice, to use its reasonable efforts to preserve intact
its business organization and assets and to refrain from issuing additional
capital stock, amending its charter, entering into or modifying material
agreements or taking certain other actions.  See "THE MERGER AGREEMENT--
Covenants."

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

     Termination of the Merger Agreement.  The Merger Agreement may be
terminated and the Merger abandoned at any time prior to the Effective Time, by
(a) the mutual consent of TINTA and TCI; (b) either TINTA or TCI (i) if the
Merger has not been consummated before January 31, 1999, unless such failure is
due to the failure of the party seeking to terminate the Merger Agreement to
perform any of its obligations thereunder, (ii) for a material breach by the
other party under the Merger Agreement that is incapable of being cured, (iii)
if a court of competent jurisdiction has issued an order permanently enjoining
or otherwise prohibiting the Merger, or (iv) if the required adoption of the
Merger Agreement by the TINTA stockholders has not been duly obtained, provided
the terminating party has complied with its obligations contained in the Merger
Agreement regarding the Meeting and applicable SEC filings; or (c) TCI (i) if
the product of 0.58 and the LMG Market Price on the Closing Date is less than
$22.00, or (ii) if the TINTA Board has withdrawn or modified in any manner
adverse to TCI its recommendation to TINTA stockholders regarding the adoption
of the Merger Agreement.  See "THE MERGER AGREEMENT--Termination, Amendment and
Waiver."

     Indemnification.  The Merger Agreement provides that the present and former
directors, officers, employees and agents of TINTA and any of its subsidiaries,
and any person who is or was serving at the request of TINTA as a director,
officer, employee or agent of another entity, will be indemnified by TCI from
and after the Effective Time against certain liabilities to the extent that (a)
a corporation is permitted under Delaware law to indemnify its own directors,
officers, employees or agents, as the case may be, (b) such person would be
entitled to be indemnified by TINTA with respect to the liability in question
under the TINTA Charter and TINTA's Bylaws and under any indemnification
agreement with TINTA and (c) such indemnification otherwise is permitted by
applicable law.  See "THE MERGER AGREEMENT--Indemnification."

     Accounting Treatment.  The Merger will be accounted for by TCI as a
"purchase" of a minority interest, as such term is used under generally accepted
accounting principles, for accounting and financial reporting purposes.

     Certain Litigation.  For information regarding certain litigation relating
to the Merger, see "THE MERGER--Certain Litigation."

INTERESTS OF CERTAIN PERSONS IN THE MERGER

     In considering the recommendations of the TINTA Board with respect to the
Merger, stockholders should be aware that some of the members of TINTA's
management and the TINTA Board have certain interests in the Merger that are in
addition to or different from the interests of stockholders of TINTA generally.
See "THE MERGER--Interests of Certain Persons in the Merger."  The TINTA Board
was aware of these interests and considered them, among other matters, in
approving the Merger Agreement.

FAIRNESS OPINION

     Salomon Smith Barney was retained on behalf of the TINTA Board to review
the fairness, from a financial point of view, of the Exchange Ratio to holders
of TINTA Common Stock.  On August 21, 1998, Salomon Smith Barney delivered an
oral opinion (which it subsequently confirmed in writing) to the TINTA Board to
the effect that, as of the date thereof, and based upon the assumptions made,
matters considered and limits of the review, as set forth in such opinion, the
Exchange Ratio was fair, from a financial point of view, to the holders of TINTA
Common Stock (other than TCI and its subsidiaries (the "TCI Holders")).  A copy
of Salomon Smith Barney's opinion, which sets forth the assumptions made, the
matters considered and the scope of review undertaken, is included as Appendix
II to this Proxy Statement/Prospectus.  See "THE MERGER--Fairness Opinion."

REGULATORY MATTERS

     Consummation of the Merger requires the giving of notices to foreign
authorities that have jurisdiction over cable television systems operated by
certain of TINTA's subsidiaries and affiliates.  Such notices will be given
before consummation of the Merger.  Other than the foregoing and other than
compliance with certain requirements of federal and state securities laws, TINTA
and TCI are not aware of any foreign, federal or state regulatory requirements
that must be complied with or approvals that must be obtained by them in
connection with the Merger.  Holders of TINTA

Common Stock who, pursuant to the Merger, will be acquiring shares of LMG Series
A Stock having a value of more than $15 million or a value which, when
aggregated with the value of shares of capital stock of TCI entitled to vote
generally in the election of directors owned by such persons prior to the
Merger, exceeds $15 million, may be subject to the notification and waiting
period requirements of the Hart-Scott-Rodino Antitrust Improvements Act of 1976,
as amended (the "HSR Act"). All such waiting periods would have to expire or be
terminated before any issuance of LMG Series A Stock in the Merger to those
particular stockholders could be effected.

ABSENCE OF APPRAISAL RIGHTS

     Holders of shares of TINTA Common Stock will not be entitled to appraisal
rights in connection with the Merger under Delaware law.  See "THE MERGER--
Absence of Appraisal Rights."

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

     The Merger is intended to be a tax-free reorganization so that no gain or
loss would be recognized by the holders of TINTA Common Stock, except in respect
of cash received in lieu of fractional shares.  Each of TCI and TINTA has
received an opinion of counsel to the effect that the Merger will qualify as a
reorganization under Section 368(a) of the Internal Revenue Code of 1986, as
amended (the "Code"), and that no gain or loss will be recognized by the
stockholders of TINTA to the extent they receive shares of LMG Series A Stock in
exchange for their TINTA Common Stock in the Merger.  Each party's obligation to
consummate the Merger is conditioned upon such opinion of its counsel not being
withdrawn prior to the Closing Date.  See "THE MERGER--Certain Federal Income
Tax Consequences."

THE AT&T MERGER AND THE LIBERTY/VENTURES COMBINATION

     On June 23, 1998, TCI and AT&T entered into the AT&T Agreement, pursuant to
which TCI will be acquired by AT&T through the AT&T Merger.  As a result of the
AT&T Merger, TCI will become a wholly-owned subsidiary of AT&T, and stockholders
of TCI will become stockholders of AT&T.  See "THE AT&T MERGER AND THE
LIBERTY/VENTURES COMBINATION--Consideration to be Received by Holders of TCI
Common Stock in the AT&T Merger."

     In a separate proposed transaction, TCI has announced its intention to
consummate the Liberty/Ventures Combination, whereby each share of TCIVG Series
A Stock will be reclassified as 0.52 of a share of LMG Series A Stock and each
share of TCIVG Series B Stock will be reclassified as 0.52 of a share of LMG
Series B Stock, and in connection with such reclassification, the assets and
businesses of the Liberty Media Group and the TCI Ventures Group will be
combined.  The Liberty/Ventures Combination is expected to occur prior to, but
is not conditional upon, the consummation of the AT&T Merger.  Following the
Liberty/Ventures Combination, the LMG Stock will reflect the separate
performance of the businesses and assets attributed to the combined
Liberty/Ventures Group.  Consummation of the Liberty/Ventures Combination is
subject to certain conditions, including approval of the TCI stockholders.
Moreover, TCI has no contractual obligation to effect the Liberty/Ventures
Combination.  Accordingly, there can be no assurance that the Liberty/Ventures
Combination will be consummated.  See "THE AT&T MERGER AND THE LIBERTY/VENTURES
COMBINATION-- Liberty/Ventures Combination."

     In connection with the consummation of the AT&T Merger, each share of LMG
Series A Stock will be converted into one share of Class A Liberty Group Common
Stock, $1.00 par value per share, of AT&T ("AT&T Liberty/Ventures Class A
Stock"), and each share of LMG Series B Stock will be converted into one share
of Class B Liberty Group Common Stock, $1.00 par value per share, of AT&T ("AT&T
Liberty/Ventures Class B Stock" and, together with the AT&T Liberty/Ventures
Class A Stock, "AT&T Liberty/Ventures Stock").  In addition, (i) if the
Liberty/Ventures Combination has not occurred prior to the AT&T Merger, each
share of TCIVG Series A Stock will be converted into the right to receive 0.52
of a share of AT&T Liberty/Ventures Class A Stock and each share of TCIVG Series
B Stock will be converted into the right to receive 0.52 of a share of AT&T
Liberty/Ventures Class B Stock and (ii) shares of TCI Group Stock will be
converted into shares of AT&T's common stock, $1.00 par value per share ("AT&T
Common Stock"), upon consummation of the AT&T Merger, as provided in the AT&T
Merger Agreement.

<PAGE>
 
- --------------------------------------------------------------------------------

The AT&T Liberty/Ventures Stock to be issued in the AT&T Merger will be a newly
authorized class of common stock of AT&T which will be intended to reflect the
separate performance of the businesses and assets attributed to the
Liberty/Ventures Group. Following the AT&T Merger, the Liberty/Ventures Group
will comprise the corporations, partnerships and other entities and interests
which, at the time of the AT&T Merger, comprise the Liberty/Ventures Group or,
if the Liberty/Ventures Combination has not occurred, the Liberty Media Group
and the TCI Ventures Group (except for certain assets that the TCI Ventures
Group will transfer to the TCI Group for cash prior to the AT&T Merger, as
contemplated by the AT&T Agreement). AT&T will own 100% of the businesses and
assets attributed to the Liberty/Ventures Group but the day-to-day management of
the businesses of the Liberty/Ventures Group will continue to be managed by
certain members of TCI's management who currently manage the businesses of the
Liberty Media Group and the TCI Ventures Group and will remain independent of
AT&T management. See "THE AT&T MERGER AND THE LIBERTY/VENTURES COMBINATION."

     It is expected that the Merger will be consummated prior to the anticipated
closing date of the AT&T Merger. In such event and assuming the AT&T Merger is
consummated, shares of TINTA Common Stock that are converted into shares of LMG
Series A Stock in the Merger will ultimately be converted into the right to
receive shares of AT&T Liberty/Ventures Class A Stock upon consummation of the
AT&T Merger in accordance with the AT&T Agreement. Consummation of the Merger,
however, is not contingent on the consummation of the AT&T Merger or the other
transactions contemplated by the AT&T Agreement, and in the event such
transactions are abandoned, former TINTA stockholders would continue to own
shares of LMG Series A Stock.  Consummation of the AT&T Merger is subject to the
separate approvals of the stockholders of AT&T and TCI, receipt of all necessary
governmental consents and approvals and other conditions to closing set forth in
the AT&T Agreement.  Accordingly, there can be no assurance that the AT&T Merger
will be consummated.  See "THE AT&T MERGER AND THE LIBERTY/VENTURES
COMBINATION."

COMPARATIVE MARKET PRICE DATA

Stock were $41 6/8 and $21 7/8 per share, respectively. On _______________,
1998, the last full trading day before the date of printing this Proxy

DIVIDENDS

     TCI.  TCI and its predecessors have never paid any cash dividends with
respect to its common stock.  TCI anticipates that no cash dividends will be
paid on the LMG Series A Stock for the foreseeable future.  Payment of cash
dividends on the LMG Series A Stock, if any, in the future will be determined by
the Board of Directors of TCI (the "TCI Board") in light of the financial
condition, results of operations and business requirements of TCI, taken as a
whole, and subject to the provisions described under "DESCRIPTION OF TCI CAPITAL
STOCK--Common Stock--Dividends."  As a holding company, TCI's ability to pay
cash dividends is dependent on its ability to receive cash dividends and
advances from its subsidiaries.  Certain loan agreements to which certain
subsidiaries of TCI are parties or are subject contain provisions that limit the
amount of dividends, other than stock dividends, that such companies may pay.
Future loan agreements may contain similar restrictions.  Payment of dividends
by TCI is also subject to the terms of any series of TCI preferred stock.  See
"DESCRIPTION OF TCI CAPITAL STOCK--Common Stock--Dividends."

     TINTA.  TINTA has never paid any cash dividends with respect to the TINTA
Common Stock and, pursuant to the Merger Agreement, has agreed not to pay any
dividends on the TINTA Common Stock prior to the Effective Time of the Merger.
TINTA is a holding company and its ability to obtain funds for the payment of
cash dividends from its subsidiaries and affiliates is severely limited.  In
addition, TINTA is prohibited by the terms of the Credit Facility from paying
cash dividends on its capital stock.  See "CERTAIN TRANSACTIONS BETWEEN TCI AND
TINTA-- Transactions with TCI and Others--Credit Facility."

CERTAIN COMPARATIVE PER SHARE DATA

     The following table sets forth certain historical comparative data related
to book value and earnings (loss) per common share on a historical basis for the
Liberty Media Group and TINTA, on a pro forma basis for the Liberty Media Group
and on a pro forma equivalent basis for TINTA.  The Liberty Media Group pro
forma book value per share information gives effect to the Merger as if it had
occurred on June 30, 1998.  The Liberty Media Group pro forma earnings per share
information gives effect to the Merger as if it had occurred on January 1, 1997.
The following information should be read in conjunction with the consolidated
historical financial statements and notes thereto of TCI and TINTA, which are
incorporated by reference into this Proxy Statement/Prospectus.  See
"INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE."  The following information

________________

(a) The computations of the pro forma book value per share of the LMG Stock is
    based upon 368 million shares of LMG Stock that would have been outstanding
    on June 30, 1998 if the Merger had occurred on such date, and upon the
    attribution of TCI's net assets as of June 30, 1998 to each of the Liberty
    Media Group, the TCI Group and the TCI Ventures Group.  Shares of LMG Stock,
    TCI Group Stock and TCIVG Stock represent ownership interests in TCI and the
    attributed net assets of the Liberty Media Group, the TCI Group and the TCI
    Ventures Group are not necessarily indicative of the allocation of any
    proceeds remaining upon any liquidation of TCI.  In this regard, any such
    liquidation proceeds remaining for distribution to holders of LMG Stock, TCI
    Group Stock and TCIVG Stock would be allocated based upon the respective
    aggregate market capitalization of the outstanding LMG Stock, TCI Group
    Stock and TCIVG Stock.
(b) The pro forma basic earnings attributable to common stockholders per common
    and common equivalent share for the six months ended June 30, 1998 is based
    upon 366 million weighted average shares.  Such amount was calculated
    utilizing 356 million weighted average shares (as disclosed in TCI's
    historical financial statements) increased by an estimated 10 million shares
    to be issued upon consummation of the Merger.
(c) The pro forma basic earnings attributable to common stockholders per common
    and common equivalent share for the year ended December 31, 1997 is based
    upon 376 million weighted average shares.  Such amount was calculated
    utilizing 366 million weighted average shares (as disclosed in TCI's
    historical financial statements) increased by an estimated 10 million shares
    to be issued upon consummation of the Merger.
(d) The pro forma diluted earnings attributable to common stockholders per
    common and common equivalent share for the six months ended June 30, 1998 is
    based upon 401 million diluted weighted average shares.  Such amount was
    calculated utilizing 391 million diluted weighted average shares (as
    disclosed in TCI's historical financial statements) increased by an
    estimated 10 million shares to be issued upon consummation of the Merger.
(e) The pro forma diluted earnings attributable to common stockholders per
    common and common equivalent share for the year ended December 31, 1997 is
    based upon 413 million diluted weighted average shares.  Such amount was
    calculated utilizing 403 million diluted weighted average shares (as
    disclosed in TCI's historical financial statements) increased by an
    estimated 10 million shares to be issued upon consummation of the Merger.
(f) The indicated TINTA equivalents are determined by multiplying the pro forma
    Liberty Media Group amounts by the Exchange Ratio of 0.58 of a share of LMG
    Series A Stock for each share of TINTA Common Stock.  As described under
    "THE MERGER AGREEMENT-- Consideration to be Received in the Merger," if the
    product of 0.58 and the LMG Market Price on the Closing Date is less than
    $22.00, TCI must either (i) increase the exchange ratio to equal the
    quotient (rounded upwards, if necessary, to the nearest one one-thousandth)
    obtained by dividing $22.00 by such LMG Market Price or (ii) terminate the
    Merger Agreement.  The TINTA pro forma equivalent information does not give
    effect to any such potential adjustment to the Exchange Ratio.

(b) From the date of the LMG Distribution through December 31, 1995.
(c) From the date of the Exchange Offers through December 31, 1997.
(d) On March 4, 1998, TCI contributed to Cablevision Systems Corporation, a
    Delaware corporation ("CSC"), certain of its cable television systems
    serving approximately 830,000 customers in exchange for approximately 24.5
    million newly issued CSC Class A common shares (as adjusted for a stock
    dividend) (the "CSC Transaction").  CSC also assumed and repaid
    approximately $574 million of debt owed by TCI to external parties and $95
    million of debt owed to TCI.  TCI has also entered into letters of intent
    with CSC which provide for TCI to acquire a cable system in Michigan and an
    additional 3% of CSC's Class A common shares and for CSC to (i) acquire
    cable systems serving approximately 250,000 customers in Connecticut and
    (ii) assume $110 million of TCI's debt.  The ability of TCI to sell or
    increase its investment in CSC is subject to certain restrictions and
    limitations set forth in a stockholders agreement with CSC.  In addition,
    during the first six months of 1998, TCI completed three transactions
    whereby TCI contributed cable television systems serving in the aggregate
    approximately 670,000 customers to three separate joint ventures
    (collectively, the "1998 Joint Ventures") in exchange for non-controlling
    ownership interests in each of the 1998 Joint Ventures, and the assumption
    and repayment by the 1998 Joint Ventures of debt owed by TCI to external
    parties aggregating $323 million and intercompany debt owed to TCI
    aggregating $833 million.  In connection with such transactions, TCI has
    agreed to take certain steps to support compliance by each of the 1998 Joint
    Ventures with their payment obligations under certain debt instruments, up
    to an aggregate contingent commitment of $784 million.  The CSC Transaction
    and the formation of the 1998 Joint Ventures are collectively referred to
    herein as the "1998 Contribution Transactions."  Including the 1998
    Contribution Transactions, TCI, as of July 31, 1998, has, since January 1,
    1997, contributed, or signed agreements or letters of intent to contribute
    within the next twelve months, certain cable television systems (the
    "Contributed Cable Systems") serving approximately 3.9 million basic
    customers to joint ventures in which TCI will retain non-controlling
    ownership interests (the "Contribution Transactions").  Following the
    completion of the Contribution Transactions, TCI will no longer consolidate
    the Contributed Cable Systems.  Accordingly, it is anticipated that the
    completion of the Contribution Transactions, as currently contemplated, will
    result in an aggregate estimated reduction (based on actual amounts with
    respect to the 1998 Contribution Transactions and currently contemplated
    amounts with respect to the pending Contribution Transactions) to TCI's debt
    of $4.8 billion and aggregate estimated reductions (based on 1997 amounts)
    to TCI's annual revenue and annual operating income before depreciation,
    amortization and other non-cash items and stock compensation of $1.8 billion
    and $815 million, respectively.  No assurance can be given that any of the
    pending Contribution Transactions will be consummated.

    "Telewest UK Joint Venture") to Old Telewest.  As a result of the Old
    Telewest IPO, TINTA's 50% ownership in the Telewest UK Joint Venture was
    converted into a 37.8% interest in Old Telewest.  On October 3, 1995, Old
    Telewest consummated a business combination (the "SBCC Transaction") with
    SBC CableComms (UK) ("SBCC") pursuant to which a new entity, Telewest
    Communications plc ("Telewest"), acquired all of the outstanding share
    capital of Old Telewest and SBCC.  The SBCC Transaction effectively resulted
    in the conversion of TINTA's 37.8% indirect ownership interest in Old
    Telewest into a 26.8% indirect ownership interest in Telewest. All
    references herein to "Telewest" include Telewest and its predecessor
    entities (Old Telewest and the Telewest Joint Venture), unless the context
    indicates otherwise.
(f) Represents the estimated net present value of TINTA's obligation to
    contribute an additional 264 million French francs to MultiThematiques S.A.
    Such obligation was completely satisfied during 1997.
(g) In connection with the dilution of TINTA's ownership interest in Telewest
    that occurred in 1996, 1995 and 1994, TINTA recognized non-cash gains of
    $258,000, $164.9 million and $161.5 million (before deducting the related
    tax expense of $90,000, $57.7 million and $56.5 million, respectively).  The
    1995 gain was recognized in connection with the SBCC Transaction, and the
    1994 gain was recognized in connection with the Old Telewest IPO.
(h) On July 18, 1995, TINTA completed its initial public offering, in which
    20,000,000 shares of TINTA Series A Stock were sold to the public for net
    proceeds of approximately $301.3 million.  In connection with its initial
    public offering, TINTA amended and restated it certificate of incorporation
    on July 12, 1995 to, among other things, (i) increase its authorized capital
    stock and (ii) divide its common stock into two series.  At the same time,
    TINTA effected a reclassification pursuant to which the 1,000 shares of
    TINTA common stock held by TCI were reclassified and changed into 85,800,000
    shares of TINTA Series A Stock and 11,700,000 shares of TINTA Series B
    Stock.  The pro forma earnings (loss) per common share calculations give
    effect to such reclassification as if it had occurred on January 1, 1994,
    and accordingly, assume 106.8 million and 97.5 million weighted average
    shares of TINTA Common Stock were outstanding during the years ended
    December 31, 1995 and 1994, respectively.

                                 RISK FACTORS

     The following factors, among others, should be considered carefully by
TINTA stockholders in considering whether to vote in favor of the Merger.
Certain capitalized terms used below that have not previously been defined have
the meanings specified under "DESCRIPTION OF TCI CAPITAL STOCK--Common Stock."

STOCKHOLDERS OF ONE COMPANY; FINANCIAL EFFECTS ON ONE GROUP COULD AFFECT OTHER
BUSINESSES

     TCI holds title to all of its assets and is responsible for all of its
liabilities, and the holders of TCI Common Stock have no specific claim against
the assets attributed for financial statement presentation purposes to the Group
whose performance is associated with the particular series of TCI Common Stock
they hold.  Holders of LMG Stock are common stockholders of TCI and are subject
to risks associated with an investment in TCI and all of its businesses, assets
and liabilities.

     The financial results of one Group that affect TCI's consolidated results
of operations or financial condition could affect the combined results of
operations and financial condition of the other Groups.  Likewise, events
affecting one Group could affect the market price of the LMG Stock, the TCI
Group Stock and the TCIVG Stock.  In addition, any net losses of any Group,
dividends or distributions on, or repurchases of, the LMG Stock, the TCI Group
Stock or the TCIVG Stock, and dividends on, or certain repurchases of, TCI
Preferred Stock, will reduce funds of TCI legally available for the payment of
dividends on the LMG Stock, the TCI Group Stock and the TCIVG Stock.  The
combined financial statements of the LMG Stock, the TCI Group Stock and the
TCIVG Stock should be read in conjunction with the consolidated financial
statements of TCI.  The combined financial statements of each Group principally
reflect the combined financial position, results of operations and cash flows of
the businesses and investments included therein. However, each Group's financial
information could also include allocated portions of the individual assets and
liabilities that are not separately identified with the operations of a specific
Group.

LIMITED SEPARATE STOCKHOLDER RIGHTS; EFFECTS ON VOTING POWER

     Holders of LMG Stock do not have any legal rights specifically related to
the assets attributed to the Liberty Media Group or have any right to vote on
matters as a separate class, other than (i) as set forth in the provisions
relating to dividend and liquidation rights and requirements for mandatory
dividend, redemption or conversion of LMG Stock upon the disposition of all or
substantially all of the properties and assets of the Liberty Media Group as
described under "DESCRIPTION OF TCI CAPITAL STOCK--Common Stock--Conversion and
Redemption" and (ii) separate voting rights in limited circumstances as required
by the DGCL.  Separate meetings for the holders of LMG Stock are not held.

     Holders of LMG Stock, TCI Group Stock and TCIVG Stock and any TCI Preferred
Stock having general voting rights, vote as one class on all matters coming
before any meeting of stockholders and do not have any separate class voting
rights except in limited circumstances as required by the DGCL.  Under the DGCL,
the holders of the outstanding shares of a class are entitled to vote as a class
upon a proposed amendment to a corporation's certificate of incorporation,
whether or not entitled to vote on such amendment by the certificate of
incorporation, if the amendment would increase or decrease the aggregate number
of authorized shares of such class, increase or decrease the par value of the
shares of such class, or alter or change the powers, preferences or special
rights of the shares of such class so as to affect them adversely.  For this
purpose, if a proposed amendment would alter or change the powers, preferences
or special rights of one or more series of any class so as to affect them
adversely, but would not so affect the entire class, then only the shares of the
series so affected by the amendment would be entitled to vote as a separate
class on the amendment.  Accordingly, a proposed amendment the adverse effect of
which on the powers, preferences or special rights of any series of TCI Common
Stock does not differ from its adverse effect on the powers, preferences or
special rights of any other series of TCI Common Stock would not entitle such
series to vote as a class separately from the other series of TCI Common Stock.

     Certain matters on which holders of LMG Stock, TCI Group Stock and TCIVG
Stock might vote together as a single class could involve a divergence or the
appearance of a divergence of interests among the holders of such series 

                                       13
<PAGE>
 
of TCI Common Stock. For example, TCI's Restated Certificate of Incorporation,
as amended (the "TCI Charter"), does not require that a merger or consolidation
of TCI requiring the approval of TCI's stockholders be approved by a separate
vote of holders of any series of TCI Common Stock, and Delaware law requires
such approval only in certain circumstances. As a result, if holders of any one
or more series of TCI Common Stock that possess the requisite voting power vote
to approve the merger or consolidation, then the merger or consolidation could
be consummated even if the holders of a majority of some other series of TCI
Common Stock vote against the merger or consolidation. See "--Potential
Divergence of Interests; No Specific Procedures for Resolution." Immediately
following the issuance of shares of LMG Series A Stock in the Merger, the
combined voting power of the TCI Group Series A Stock and TCI Group Series B
Stock would represent a majority of the voting power of all classes and series
entitled to vote in the election of directors.

     The LMG Series A Stock has one vote per share and the LMG Series B Stock
has ten votes per share.  The TCI Group Series A Stock and TCIVG Series A Stock
have one vote per share and the TCI Group Series B Stock and TCIVG Series B
Stock have ten votes per share.  See "DESCRIPTION OF TCI CAPITAL STOCK--Common
Stock--Voting Rights."

POTENTIAL DIVERGENCE OF INTERESTS; NO SPECIFIC PROCEDURES FOR RESOLUTION

     The existence of separate series of TCI Common Stock may give rise to
occasions when the interests of the holders of LMG Stock and the holders of
either TCI Group Stock or TCIVG Stock, or both, may diverge or appear to
diverge.  As further discussed below, examples include, among others,
determinations by the TCI Board to (i) convert each outstanding share of LMG
Stock into shares of TCI Group Stock, (ii) approve the disposition of all or
substantially all of the properties and assets of the Liberty Media Group, (iii)
allocate consideration to be received by holders of TCI Common Stock in
connection with a merger or consolidation involving TCI among holders of
different series of TCI Common Stock, (iv) allocate resources and financial
support to or pursue business opportunities or operational strategies through
one Group instead of one or more of the other Groups, (v) if and to the extent
the TCI Group has an Inter-Group Interest in the Liberty Media Group, allocate
the proceeds of issuances of LMG Stock either to the TCI Group in respect of a
reduction in its Inter-Group Interest in the Liberty Media Group or to the
equity of the Liberty Media Group, (vi) pay or omit dividends on the LMG Stock,
the TCI Group Common Stock or the TCIVG Stock or (vii) approve transactions
involving the transfer of funds or assets from one Group to one or more of the
other Groups or make other operational or financial decisions with respect to
one Group that could be considered to be detrimental to one or more of the other
Groups.  Except for certain management and allocation policies adopted by the
TCI Board with respect to cash management, corporate expenses, allocation of
assets and liabilities and inter-Group transactions (any and all of which could
be modified or rescinded by the TCI Board in its sole discretion and without
approval of stockholders), no specific procedures have been adopted for
consideration of matters involving a divergence of interests among the holders
of LMG Stock, TCI Group Stock and TCIVG Stock.  Rather than develop additional
specific procedures in advance, the TCI Board has determined to exercise its
judgment from time to time, depending on the circumstances, as to how best to
obtain information regarding the divergence (or potential divergence) of
interests, under what circumstances to seek the assistance of outside advisers,
whether a committee of the TCI Board should be appointed to address the matter
and how to assess which available alternative is in the best interests of TCI
and all of its stockholders.  The TCI Board believes the advantages of retaining
flexibility in determining how best to fulfill its responsibilities in such
circumstances as they may arise outweigh any perceived advantages from adopting
additional specific procedures in advance.

     Optional Conversion of LMG Stock into TCI Group Stock.  The TCI Board may
determine to convert each outstanding share of LMG Series A Stock into shares of
TCI Group Series A Stock and each outstanding share of LMG Series B Stock into
shares of TCI Group Series B Stock, in each case determined based upon the ratio
of the value (as determined on the basis of appraisals performed by investment
banking firms) of one share of LMG Stock to the average Market Value over a 20-
Trading Day period prior to the date such appraisal process is initiated of one
share of TCI Group Series A Stock.  Such a conversion could be effected at any
time, including at a time when the value of one share of LMG Stock determined by
appraisal differs significantly from the market value of the LMG Stock reflected
in the trading markets, or at a time when the Market Value of the TCI Group
Stock used in the determination of the conversion

                                       14
<PAGE>
 
ratio reflects what might be considered an overvaluation or undervaluation.
Basing the conversion ratio on an appraised value determination for the LMG
Stock and a trading market valuation for the TCI Group Stock could result in the
conversion ratio being significantly different from that which would have
resulted if the same measure were used for the valuation of both the TCI Group
Stock and the LMG Stock. For example, a conversion could be considered dilutive
of the interests of the holders of the LMG Stock if the Market Value of the TCI
Group Stock is greater than the valuation of the TCI Group Stock that would have
resulted if a similar appraisal procedure to that used in the determination of
the value of the LMG Stock were used. Such a conversion would also have the
effect of precluding holders of LMG Stock from retaining their investment in a
security intended to reflect separately the businesses and assets attributed to
the Liberty Media Group.

     Disposition of Group Assets.  As long as the assets attributed to a Group
continue to represent less than substantially all of the properties and assets
of TCI, the TCI Board may approve sales and other dispositions of any amount of
the properties and assets attributed to such Group without stockholder approval
because, under the DGCL and the TCI Charter, stockholder approval is required
only for a sale or other disposition of all or substantially all of the
properties and assets of TCI as a whole.  The TCI Charter, however, contains
provisions which, in the event of a Disposition of all or substantially all of
the properties and assets attributed to the Liberty Media Group in one
transaction or a series of related transactions, other than in certain specified
transactions, including a transaction in which TCI receives primarily equity
securities of an entity engaged or proposing to engage primarily in a similar or
complementary business, and other than in connection with the disposition of all
of the assets of TCI in its entirety, require TCI, at its option, either to (i)
distribute by dividend or redemption to the holders of LMG Series A Stock and
LMG Series B Stock an amount in cash and/or securities or other property equal
to their proportionate interest in the Liberty Media Group Net Proceeds of such
Disposition or (ii) convert outstanding shares of LMG Series A Stock into a
number (or fraction) of shares of TCI Group Series A Stock and convert
outstanding shares of LMG Series B Stock into a number (or fraction) of shares
of TCI Group Series B Stock, equal in each case to 110% of the average daily
ratio of the Market Value of a share of LMG Series A Stock to the Market Value
of a share of TCI Group Series A Stock over a specified period following such
Disposition.  The provisions of the TCI Charter do no require the TCI Board to
select the option which would result in the distribution with the highest value
to the holders of the LMG Stock or with the smallest effect on the TCI Group
Stock.  The TCI Charter does not require TCI to take such actions upon sales or
other dispositions of less than substantially all of the properties and assets
of the Liberty Media Group or upon two or more unrelated sales or other
dispositions which together constitute the sale of substantially all of the
properties and assets of the Liberty Media Group.  In addition, although the TCI
Charter contains comparable provisions relating to a disposition of all or
substantially all of the properties and assets of the TCI Ventures Group, the
TCI Charter does not contain comparable provisions relating to a disposition of
all or substantially all of the properties and assets of the TCI Group.  See
"DESCRIPTION OF TCI CAPITAL STOCK--Common Stock--Conversion and Redemption."
The appropriate disposition of proceeds in the latter case would be subject to
determination by the TCI Board in accordance with the TCI Charter, approved
allocation policies and the exercise of its fiduciary duties. See "--Fiduciary
Duties of the TCI Board Are to All TCI Stockholders Regardless of Class or
Series."

     Allocation of Proceeds of Mergers or Consolidations.  The TCI Charter does
not contain any provisions governing how consideration to be received by TCI's
stockholders in connection with a merger or consolidation involving TCI (in
which the TCI Common Stock is to be converted into other securities, cash or
other property) is to be allocated among holders of LMG Stock, TCI Group Stock
and TCIVG Stock.  In any such merger or consolidation, the allocation of
consideration would be determined by the TCI Board.  See "--Limited Separate
Stockholder Rights; Effects on Voting Power."

     Allocation of Resources and Financial Support; Pursuit of Business
Opportunities or Operational Strategies. The TCI Board could from time to time
allocate resources and financial support to or pursue business opportunities or
operational strategies through one Group instead of the other Groups.  The
decision to allocate resources and financial support to one Group may adversely
affect the ability of the other Groups to obtain funds sufficient to implement
their business strategies.

                                       15
<PAGE>
 
     Allocation of Proceeds Upon Issuance of LMG Stock.  If and to the extent
that the TCI Group has an Inter-Group Interest in the Liberty Media Group at the
time of any sale by TCI of shares of LMG Stock, the TCI Board would determine
the allocation of the proceeds of such sale between the TCI Group and the
Liberty Media Group.  In such case, the TCI Board could allocate up to 100% of
the net proceeds of such sale of LMG Stock to the TCI Group or to the Liberty
Media Group, and such net proceeds would be attributed entirely to and reflected
entirely on the combined financial statements of the Group to which such
proceeds were allocated.  Any such allocation of net proceeds to the TCI Group
would reduce any then existing Inter-Group Interest in the Liberty Media Group.

     No Assurance of Payment of Dividends. TCI has never paid cash dividends on
the TCI Common Stock.  The TCI Board does not currently intend to pay cash
dividends on the LMG Stock, the TCI Group Stock or the TCIVG Stock.  Any
dividends on the LMG Stock which may be declared by the TCI Board will be
payable out of the lesser of (i) the funds of TCI legally available for such
purpose, which are determined on the basis of TCI in its entirety, and (ii) the
Liberty Media Group Available Dividend Amount.  Such dividends are further
subject to the prior payment of dividends on outstanding shares of any class or
series of capital stock of TCI with preferential dividend provisions.  Any net
losses of TCI (without regard to whether such losses arose from any specific
Group), any dividends or distributions on, or repurchases of, the TCI Group
Stock or the TCIVG Stock, and dividends on, and certain repurchases of, TCI
Preferred Stock, will reduce the funds of TCI legally available for payment of
dividends on the LMG Stock.  Subject to limitations of the DGCL and the TCI
Charter, the TCI Board may declare and pay dividends on the LMG Stock, the TCI
Group Stock and the TCIVG Stock in equal or unequal amounts, or may decide not
to declare and pay such dividends, notwithstanding the relationship among the
Liberty Media Group Available Dividend Amount, the TCI Group Available Dividend
Amount and the TCI Ventures Group Available Dividend Amount, the respective
amounts of prior dividends paid on, or liquidation rights of, the LMG Stock, the
TCI Group Stock or the TCIVG Stock or any other factor.  See "DESCRIPTION OF TCI
CAPITAL STOCK--Common Stock--Dividends."

     Operational and Financial Decisions.  The TCI Board could from time to time
make operational and financial decisions that affect the Groups
disproportionately, such as transfers of funds or assets among the Groups, the
allocation of funds for capital expenditures, the determination to expand into
new areas and the allocation of resources and personnel that may be suitable for
more than one Group.  The decision to provide funds to one Group may adversely
affect the ability of the other Groups to obtain funds sufficient to implement
their business strategies.  For further discussion of potential divergence of
interests arising from financial decisions, see "--Transfer of Funds among
Groups; Equity Contributions from the TCI Group."

FIDUCIARY DUTIES OF THE TCI BOARD ARE TO ALL TCI STOCKHOLDERS REGARDLESS OF
CLASS OR SERIES

     Under Delaware law, the TCI Board has a duty to act with due care and in
the best interests of all TCI stockholders, including the holders of LMG Stock,
TCI Group Stock and TCIVG Stock.  The existence of the LMG Stock, the TCI Group
Stock and the TCIVG Stock may give rise to occasions when the interests of the
holders of one or more series of TCI Common Stock and the holders of the other
series of TCI Common Stock may diverge or appear to diverge.  See "--Potential
Divergence of Interests; No Specific Procedures for Resolution."  The TCI Board
will address and resolve any issues involving a material divergence of interests
among the holders of the separate series of TCI Common Stock.

     Although TCI is not aware of any precedent concerning the manner in which
principles of Delaware law would be applied in the context of a capital
structure involving multiple classes or series of capital stock the rights of
which include terms designed to reflect the separate performance of specified
businesses, principles of Delaware law provide that a board of directors must
act in accordance with its good faith business judgement of the corporation's
best interests, taking into consideration the interests of all stockholders
regardless of class or series.  Under these principles of Delaware law and the
"business judgment rule," a good faith determination made by a disinterested and
adequately informed TCI Board with respect to any matter having a disparate
impact upon the holders of LMG Stock, the holders of TCI Group Stock and the
holders of TCIVG Stock would be a defense to any challenge to such determination
made by or on behalf of any of such Groups of holders.  Nevertheless, a Delaware
court hearing a case involving such a challenge may decide to apply principles
of Delaware law other than those discussed above, or may fashion new 

                                       16
<PAGE>
 
principles of Delaware law, in order to decide such a case, which would be a
case of first impression. There may arise circumstances involving a divergence
of interests in which the TCI Board is held to have properly discharged its
responsibilities to act with due care and in the best interests of TCI and all
of its stockholders, but in which holders of the LMG Stock, the TCI Group Stock
or the TCIVG Stock consider themselves to be disadvantaged relative to the other
series. In such a case, such holders would not have any other remedy under
Delaware law with respect to the circumstances giving rise to the divergence of
interests.

     Disproportionate ownership interests of members of the TCI Board in the LMG
Stock, the TCI Group Stock and the TCIVG Stock or disparate values of the LMG
Stock, the TCI Group Stock and the TCIVG Stock could create or appear to create
potential conflicts of interest when directors are faced with decisions that
could have different implications for different series.  See "--Potential
Divergence of Interests; No Specific Procedures for Resolution." Nevertheless,
TCI believes that a director would be able to discharge his or her fiduciary
responsibilities even if his or her interests in shares of LMG Stock, TCI Group
Stock and TCIVG Stock were disproportionate or had disparate values.

TRANSFER OF FUNDS AMONG GROUPS; EQUITY CONTRIBUTIONS FROM THE TCI GROUP

     All debt incurred or preferred stock issued by TCI and its subsidiaries
will be (unless the TCI Board otherwise provides) specifically attributed to and
reflected on the combined financial statements of the Group that includes the
entity which incurred the debt or issued the preferred stock or, in case the
entity incurring the debt or issuing the preferred stock is Tele-Communications,
Inc., the TCI Group.  The TCI Board could, however, determine from time to time
that debt incurred or preferred stock issued by entities included in a Group
should be specifically attributed to and reflected in the combined financial
statements of one of the other Groups to the extent that the debt is incurred or
the preferred stock is issued for the benefit of such other Group.

     To the extent cash needs of one Group exceed cash provided by such Group,
one of the other Groups may transfer funds to such Group.  Such transfers of
funds among the Groups will be reflected as borrowings or, if determined by the
TCI Board, in the case of a transfer from the TCI Group to either the Liberty
Media Group or the TCI Ventures Group, reflected as the creation of an, or an
increase in any then existing, Inter-Group Interest of the TCI Group in such
Group or, in the case of a transfer from either the Liberty Media Group or the
TCI Ventures Group to the TCI Group, reflected as a reduction in any then
existing Inter-Group Interest of the TCI Group in such Group.  There are no
specific criteria for determining when a transfer will be reflected as a
borrowing or as an increase or reduction in an Inter-Group Interest.  The TCI
Board expects to make such determinations, either in specific instances or by
setting generally applicable policies from time to time, after consideration of
such factors as it deems relevant, including, without limitation, the needs of
TCI, the financing needs and objectives of the Groups, the investment objectives
of the Groups, the availability, cost and time associated with alternative
financing sources, prevailing interest rates and general economic conditions.

     Loans from one Group to another Group would bear interest at such rates and
have such repayment schedules and other terms as are established from time to
time by, or pursuant to procedures established by, the TCI Board.  The TCI Board
expects to make such determinations, either in specific instances or by setting
generally applicable policies from time to time, after consideration of such
factors as it deems relevant, including, without limitation, the needs of TCI,
the use of proceeds by and creditworthiness of the recipient Group, the capital
expenditure plans and investment opportunities available to each Group and the
availability, cost and time associated with alternative financing sources.

     Although the creation of or any increase in an Inter-Group Interest of the
TCI Group in the Liberty Media Group resulting from an equity contribution by
the TCI Group to the Liberty Media Group or any decrease in such Inter-Group
Interest resulting from a transfer of funds from the Liberty Media Group to the
TCI Group would be determined by reference to the Market Value of the LMG Series
A Stock as of the date of such transfer, such an increase could occur at a time
when such shares could be considered undervalued and such a decrease could occur
at a time when such shares could be considered overvalued.

                                       17
<PAGE>
 
MANAGEMENT AND ALLOCATION POLICIES SUBJECT TO CHANGE

     The TCI Board has adopted certain management and allocation policies with
respect to cash management, corporate expenses and Inter-Group transactions, any
and all of which could be modified or rescinded by the TCI Board, in its sole
discretion, without the approval of stockholders.  The TCI Board could also
adopt additional policies depending upon the circumstances.  Any determination
to modify or rescind such policies, or to adopt additional policies, including
any such decision that could have disparate effects upon holders of LMG Stock,
TCI Group Stock or TCIVG Stock, would be made by the TCI Board as set forth
under "--Fiduciary Duties of the TCI Board Are to All TCI Stockholders
Regardless of Class or Series."

POTENTIAL CONVERSION OF LMG STOCK

     Solely at TCI's option, all of the outstanding shares of LMG Stock may be
converted into TCI Group Stock upon the terms described under "DESCRIPTION OF
TCI CAPITAL STOCK--Common Stock--Conversion and Redemption."  TCI cannot predict
the impact on the market prices of the LMG Stock or the TCI Group Stock of its
ability to effect any such conversion or the effect, if any, that the exercise
by TCI of this conversion right would have on the market price of the LMG Stock
or the TCI Group Stock prevailing at such time.  See "--Potential Divergence of
Interests; No Specific Procedures for Resolution."

POTENTIAL EFFECTS OF POSSIBLE DISPOSITION OF ASSETS OF THE LIBERTY MEDIA GROUP

     The terms of the LMG Stock provide that if TCI were to dispose of all or
substantially all of the properties and assets of the Liberty Media Group, other
than in a transaction in which TCI receives primarily equity securities of an
entity engaged or proposing to engage primarily in a similar or complementary
business and other than in connection with the disposition of all of the assets
of TCI, TCI would be required, at its option, either to (i) distribute to
holders of LMG Stock an amount equal to their proportionate interest in the
Liberty Media Group Net Proceeds of such Disposition, either by special dividend
or by redemption of all or part of the outstanding shares of LMG Stock, or (ii)
convert outstanding shares of LMG Stock into shares of the corresponding series
of TCI Group Stock at a conversion ratio based on 110% of the average daily
ratio of the Market Value of a share of LMG Series A Stock to the Market Value
of a share of TCI Group Series A Stock over a specified period following such
Disposition.  "Liberty Media Group Net Proceeds" means the proceeds of such
Disposition after payment of or provision for certain specified costs, including
taxes to be paid by TCI in respect of the Disposition or such dividend or
redemption, transaction costs and liabilities and other obligations (contingent
or otherwise, including obligations in respect of TCI Preferred Stock)
attributed to the Liberty Media Group.  If the Liberty Media Group were a
separate independent company and its shares were acquired by another person,
certain of those costs, including corporate and shareholder level taxes, might
not be payable in connection with such an acquisition.  As a result, the
consideration that would be received by stockholders of such a separate
independent company in connection with such a stock acquisition might be greater
than the Liberty Media Group Net Proceeds that would be received by holders of
LMG Stock if all or substantially all of the properties and assets of the
Liberty Media Group were sold.  In addition, no assurance can be given that the
Liberty Media Group Net Proceeds per share of LMG Stock to be received in
connection with a Disposition of all or substantially all of the properties and
assets of the Liberty Media Group will be equal to or more than the market value
per share of LMG Stock prior to or after announcement of such Disposition.  See
"--Potential Conversion of LMG Stock" above and "DESCRIPTION OF TCI CAPITAL
STOCK--Common Stock--Conversion and Redemption."

LIMITATIONS ON POTENTIAL ACQUISITION OF A GROUP

     If each Group were a separate publicly held corporation, any person
interested in acquiring such corporation without negotiation with management
could seek control of the outstanding stock of such corporation by means of a
tender offer or proxy contest.  Although LMG Stock is designed to reflect the
separate performance of the Liberty Media Group, a person interested in
acquiring only the Liberty Media Group without negotiation with TCI's management
would still be required to seek control of the voting power represented by all
of the outstanding capital stock of TCI, 

                                       18
<PAGE>
 
including the LMG Stock, the TCI Group Stock and the TCIVG Stock. See
"DESCRIPTION OF TCI CAPITAL STOCK--Common Stock--Voting Rights."

ABSENCE OF APPROVAL RIGHTS WITH RESPECT TO FUTURE ISSUANCES OF AUTHORIZED SHARES

     The authorized but unissued shares of capital stock would be available for
issuance from time to time by TCI at the sole discretion of the TCI Board for
any proper corporate purpose.  Such issuances could include shares of LMG Stock,
as well as the issuance of such shares upon the conversion or exercise of
securities of TCI that are convertible into or exercisable or exchangeable for
such shares.  The approval of the stockholders of TCI will not be sought by TCI
for the issuance of authorized but unissued shares of LMG Stock (or the
reissuance of previously issued shares that have been reacquired by TCI) or
securities of TCI that are convertible into or exercisable or exchangeable for
such shares, unless deemed advisable by the TCI Board or required by applicable
law, regulation or the NASDAQ/NM requirements.

ANTI-TAKEOVER CONSIDERATIONS

     The DGCL, the TCI Charter and TCI's Bylaws contain provisions which may
serve to discourage or make more difficult a change in control of TCI without
the support of the TCI Board or without meeting various other conditions. TCI is
subject to Section 203 of the DGCL, which, in general, prohibits a "business
combination" between a corporation and an "interested stockholder" for a period
of three years following the time that such stockholder became an "interested
stockholder" unless certain conditions are met.  The TCI Charter and Bylaw
provisions which may discourage or make more difficult a change in control of
TCI include the requirement of a supermajority vote to approve specified
actions, the authorization of the TCI Board to issue additional shares of Series
Preferred Stock in one or more series and to fix and state the designations,
powers, preferences, qualifications, limitations, restrictions and relative
rights of the shares of each such series without further action by TCI's
stockholders, certain procedures required in connection with the nomination of
directors of TCI and the other provisions described under "DESCRIPTION OF TCI
CAPITAL STOCK--Anti-Takeover Considerations."  In addition, the existence of
different series of TCI Common Stock presents complexities and could in certain
circumstances pose obstacles, financial and otherwise, to an acquiring person.
For example, a potential acquiror would have to take into consideration that
holders of different series of TCI Common Stock might be more or less receptive
to the acquiror's proposal, that a tender offer would have to be structured so
as to take into account different prices at which shares of the different series
might be acquired, that a merger would require allocation of consideration among
the different series of TCI Common Stock and the effects of actions TCI might
take such as causing a conversion of the LMG Stock.  The provisions of the DGCL,
the TCI Charter and TCI's Bylaws and the existence of different series of TCI
Common Stock could, under certain circumstances, prevent stockholders from
profiting from an increase in the market value of their shares as a result of a
change in control of TCI by delaying or preventing such change in control.  See
"DESCRIPTION OF TCI CAPITAL STOCK--Anti-Takeover Considerations."


                              THE SPECIAL MEETING

VOTING RIGHTS; VOTE REQUIRED FOR APPROVAL

     The TINTA Board has fixed the close of business on October 2, 1998, as the
Record Date for the determination of the TINTA stockholders entitled to notice
of and to vote at the Meeting.  Accordingly, only holders of record of shares of
TINTA Common Stock at the close of business on the Record Date will be entitled
to notice of, and to vote at, the Meeting.  At the close of business on the
Record Date, there were ______________ shares of TINTA Series A Stock
outstanding and entitled to vote, held by __________ holders of record, and
[11,700,000] shares of TINTA Series B Stock outstanding and entitled to vote,
all of which were held by TCI.  Each holder of record of shares of TINTA Series
A Stock on the Record Date is entitled to cast one vote per share on each
proposal properly submitted for the vote of the TINTA stockholders at the
Meeting.  Each holder of record of shares of TINTA Series B Stock on the Record
Date is entitled to cast ten votes per share on each such proposal.  Votes may
be cast in person or by properly executed proxy at the Meeting.  Pursuant to the
DGCL and TINTA's Bylaws, the presence, in person or by properly executed proxy,
of the holders of a majority in total voting power of the outstanding shares of
TINTA Common Stock entitled to vote at the Meeting is necessary to constitute a
quorum at the Meeting.  Abstentions will be counted in determining whether a
quorum is present.

     Under the TINTA Charter and the DGCL, adoption of the Merger Agreement
requires the affirmative vote of the majority in voting power of outstanding
shares of TINTA Series A Stock and TINTA Series B Stock entitled to vote thereon
at the Meeting, voting together as a single class.  Abstentions and broker non-
votes in respect of the Merger Agreement will have the same effect as negative
votes.  Under the DGCL, there are no dissenters' appraisal rights for TINTA
stockholders in connection with the transactions contemplated by the Merger
Agreement.  See "THE MERGER--Absence of Appraisal Rights."

     TCI has agreed pursuant to and subject to the terms of the Merger Agreement
to cause to be voted in favor of adoption of the Merger Agreement the
[86,250,000] shares of TINTA Series A Stock and [11,700,000] shares of TINTA
Series B Stock beneficially owned by it as of the Record Date, representing
approximately [92]% of the total voting power of the shares of TINTA Common
Stock entitled to vote at the Meeting.  The vote of such shares of TINTA Common
Stock beneficially owned by TCI in favor of the proposal to adopt the Merger
Agreement is sufficient to assure the presence of a quorum at the Meeting and
the approval of such proposal by the holders of TINTA Common Stock without any
action on the part of any other holder of TINTA Common Stock.  Accordingly, it
is expected that the Merger Agreement will be adopted at the Meeting.

     As of the Record Date, directors and executive officers of TINTA, and their
affiliates (other than TCI and its subsidiaries), were beneficial owners of
outstanding shares of TINTA Common Stock representing approximately [1.42]% of
the total voting power of the shares of TINTA Common Stock outstanding on such
date.  Each such director and executive officer has informed TINTA that he
intends to vote or direct the vote of all outstanding shares of TINTA Common
Stock over which he has voting control in favor of adoption of the Merger
Agreement, subject to and consistent with any fiduciary obligations in the case
of shares held as a fiduciary.  See "SECURITY OWNERSHIP OF TINTA."

PROXIES

     All shares of TINTA Common Stock represented by properly executed proxies
received prior to or at the Meeting, and not revoked, will be voted in
accordance with the instructions indicated on such proxies; however, properly
executed proxies marked "ABSTAIN," although counted for purposes of determining
whether there is a quorum at the Meeting, will not be voted.  If no instructions
are indicated, such proxies will be voted FOR the proposal to adopt the Merger
Agreement.

     At the date of this Proxy Statement/Prospectus, the TINTA Board does not
know of any business to be presented at the Meeting other than as set forth in
the notice accompanying this Proxy Statement/Prospectus.  If any other matters
should properly be presented at the Meeting for consideration, including, among
other things, 

                                       20
<PAGE>
 
consideration of a motion to adjourn the Meeting to another time and/or place,
the persons named in the enclosed form of proxy and acting thereunder will have
discretion to vote on such matters in accordance with their best judgment.

     A stockholder may revoke his or her proxy at any time prior to its use by
(i) delivering to the Secretary of TINTA a signed notice of revocation bearing a
later date than the proxy, or a duly executed later-dated proxy relating to the
same shares or (ii) attending the Meeting and voting in person.  Attendance at
the Meeting will not in itself constitute the revocation of a proxy.  Any
written notice of revocation or subsequent proxy should be sent so as to be
delivered to TINTA at Terrace Tower II, 5619 DTC Parkway, Englewood, Colorado
80111, Attention: Secretary, or hand-delivered to the Secretary of TINTA at the
aforementioned address at or before the taking of the vote at the Meeting.

EXPENSES

     Pursuant to the Merger Agreement, costs and expenses incurred in connection
with the printing and mailing of this Proxy Statement/Prospectus will be paid
90% by TCI and 10% by TINTA.  In addition to solicitation by mail, proxies may

                                  THE MERGER

BACKGROUND

     Formation of TINTA; IPO.  TINTA was incorporated in 1994 as a wholly-owned
subsidiary of TCI.  TINTA was formed by TCI as a holding company for the purpose
of consolidating TCI's ownership interests in substantially all of its
international cable and telephony assets and certain of its international
programming assets, pending a planned initial public offering of a portion of
TINTA's common stock.  By effecting such an offering, TCI intended to obtain
credit for what it believed was the substantial "hidden" value of the
international cable, telephony and programming assets that it contributed to
TINTA.

     TCI had been acquiring ownership interests since the mid-1980's in
broadband distribution and programming companies in foreign markets that TCI
believed exhibited attractive growth opportunities for providers of integrated
multi-channel television and programming services.  TCI established an
international division in 1992, and TINTA's management initially consisted
primarily of those executives of TCI who had been responsible for the operations
of TCI's former international division.  In anticipation of its initial public
offering, TINTA entered into a number of intercompany service agreements with
TCI covering a variety of matters, including lending arrangements, the provision
of TCI facilities and "back-office" services to TINTA, tax sharing arrangements
and a service agreement giving TINTA 

                                       21
<PAGE>
 
access to TCI's technology and industry expertise, including support from TCI's
cable engineering and construction groups and programming personnel.

     In July 1995, TINTA completed its initial public offering (the "IPO") of 20
million shares of TINTA Series A Stock, which at that time represented
approximately 17% of the outstanding shares of TINTA Common Stock. Immediately
following the IPO, TCI beneficially owned 81% of the TINTA Series A Stock, all
of the TINTA Series B Stock and 91% of the combined voting power of both series
of TINTA Common Stock.  Due to purchases of TINTA Series A Stock by TINTA
pursuant to a stock buy-back program announced by TINTA in January, 1997, the
shares of TINTA Series A Stock beneficially owned by TCI on the Record Date
represented 83% of the TINTA Series A Stock outstanding on that date, and the
shares of both series of TINTA Common Stock beneficially owned by TCI on the
Record Date represented 92% of the combined voting power of both series of TINTA
Common Stock outstanding on that date.

     TINTA's Business Strategy.  TINTA's business development strategy has
historically been based on the acquisition of ownership interests in, and
participation in the development and management of, distribution,
telecommunications and programming businesses in selected foreign markets.
Further to this strategy, TINTA has ownership interests in, and has participated
in the development of, distribution and programming businesses in several
markets, including the United Kingdom (through Telewest and Flextech), Japan
(through Jupiter TeleCommunications, Inc. and Jupiter Programming, Inc.) and
Argentina (through Cablevision, Torneos y Competencias S.A. and Pramer S.R.L.).

     Most recently, TINTA has placed greater emphasis on the acquisition and
development of multi-channel programming businesses.  This emphasis is
highlighted by the appointment in September 1997 of Mr. David Evans as TINTA's
President and Chief Operating Officer.  Mr. Evans' background in the television
business was largely programming oriented.  He had previously been associated
with The News Corporation Limited where he played a key role in the
establishment of British Sky Broadcasting Group plc and in the launch of Sky
Latin America, direct-to-home satellite services for the United Kingdom and
Latin America, respectively.  Mr. Evans was subsequently named TINTA's Chief
Executive Officer in January 1998.

     The TCI Offer.  Management of TCI routinely reviews TCI's investments in
its less than wholly-owned entities to determine whether it would be advisable
for TCI to continue to hold, increase or dispose of any such investment. Whether
a decision to increase or dispose of an investment is made, and the timing of
any such decision, depends on numerous factors, including the size and nature of
the investment, the perceived advantages, if any, of full or partial ownership
and management control, conditions in the relevant industry and general market
and economic conditions.

     Since the IPO, management of TCI has from time to time evaluated the
performance of TINTA and analyzed the extent to which it had achieved its
business objectives as a separate publicly-held company.  TCI's management
believed that TINTA's leverage at the holding company level, the capital needs
of its subsidiaries and affiliates, its limited access to capital and its
limited ability to access the cash flow of its less than majority-owned
subsidiaries and affiliates had restricted TINTA's ability to effectively pursue
its business development strategy and, consequently, had negatively impacted the
market price of the TINTA Series A Stock. Over the 29-month period immediately
following the IPO, stockholders had a cumulative total stockholder return of
only 12.50% on the TINTA Series A Stock compared to a cumulative total
stockholder return of 58.93% over the same period on the common stock (assuming
reinvestment of dividends) of a peer group of companies based on the Nasdaq
Telecommunications Stock Index.

     TCI's management viewed TINTA's recent emphasis on international
programming, together with the increasingly global reach of many of the
programming assets which comprise the Liberty Media Group, as offering
substantial synergies.  Management of TCI believed that combining TINTA's assets
with the assets of the Liberty Media Group would eliminate any potential
conflicts of interest between TINTA and the Liberty Media Group in respect of
business dealings between them, including potential conflicts with respect to
the carriage by TINTA's distribution companies of programming owned or
controlled by the Liberty Media Group.  Moreover, TCI's management would like to
expand the Liberty Media Group's international programming assets beyond the
programming owned by the 

                                       22
<PAGE>
 
Liberty Media Group prior to the IPO and sports programming. However, at the
time of the IPO and subsequently, TCI has stated its intention, subject to
certain exceptions, to provide to TINTA any non-sports programming opportunities
that were presented to TCI or its controlled affiliates. By acquiring the equity
interests in TINTA not already beneficially owned by TCI, Liberty Media Group
would be free to pursue any non-sports programming opportunities that were
presented to it or to TCI or any of TCI's other controlled affiliates. Finally,
TCI's management believed that the primary objective of the IPO, that being to
unlock the hidden value of the international cable, telephony and programming
assets contributed to TINTA, had been achieved and that the combination of those
assets with the programming assets of the Liberty Media Group would conceivably
result in the market giving a higher valuation to those assets.

     On July 10, 1998, Mr. Robert R. Bennett, President and Chief Executive
Officer of Liberty Media Corporation ("Liberty"), approached TINTA's Chief
Executive Officer, Mr. Evans, at a media conference in Sun Valley, Idaho and
advised him of TCI's desire to acquire, through Liberty, all of the shares of
TINTA Common Stock not already beneficially owned by TCI.  Later that day, and
after the close of trading on the NASDAQ/NM, TCI delivered a letter to TINTA
setting forth TCI's proposal for the acquisition of TINTA in a transaction to be
structured as a tax-free merger in which each share of TINTA Common Stock would
be converted into 0.58 of a share of LMG Series A Stock.  Mr. Evans notified
each of the members of the TINTA Board of TINTA's receipt of the merger
proposal.

     On July 13, 1998, TINTA publicly announced that it had received TCI's
merger proposal.  On the same day and shortly thereafter, the Class Action
Lawsuits (as defined under "--Certain Litigation") were filed in Delaware in
respect of TCI's merger proposal.  See "--Certain Litigation."

     TINTA's Response.  Shortly after Mr. Evans' receipt of TCI's proposal, he
discussed with attorneys at TINTA's outside law firm, Baker & Botts, how best to
respond to TCI's merger proposal.  Baker & Botts is also one of TCI's outside
law firms.  Mr. Evans discussed with Baker & Botts the possibility of creating a
special committee of the TINTA Board to negotiate the terms of any merger
agreement with TCI.  In discussing the possible creation of such a committee, it
was recognized that each of the TINTA directors, with the exception of Pierre
Lescure, was either an executive officer of TCI or of one of its business units,
a director of TCI, or an executive officer of TINTA.  The formation of a special
committee consisting of Mr. Evans and Mr. Lescure was discussed.  Mr. Evans was
discussed as a possible candidate as he had the least affiliation with TCI
(having joined TINTA in September 1997) and his compensation package, which
includes TINTA stock options, most closely aligned him with the interests of
TINTA's public stockholders. The participation of Mr. Lescure was discussed as
he is the only "outside" director on the TINTA Board. However, it was recognized
that Mr. Evans, under Delaware law (the corporation law that is applicable to
both TCI and TINTA), might not be deemed to be an "independent director" under
applicable Delaware case precedents, and hence any special committee on which he
served might be unable to obtain the benefits bestowed on properly constituted
special committees under Delaware law. It was also recognized that Mr. Lescure
might not be deemed to be an "independent director" under Delaware law, due to
business dealings between Canal + S.A. (of which Mr. Lescure is Chairman and
Chief Executive Officer) and TINTA.

     On July 15, 1998, the Executive Committee of the TINTA Board (the
"Executive Committee"), which is comprised of Mr. Evans, John C. Malone (the
Chairman of the Board of TINTA and Chairman of the Board and Chief Executive
Officer of TCI), and Paul A. Gould (a director of TINTA and TCI), met by
telephone conference call.  The Executive Committee discussed the feasibility
and desirability of forming a special committee, consisting of Mr. Evans and Mr.
Lescure, to negotiate the terms of any merger agreement with TCI. However, it
was determined that no such committee would be formed because, as explained
above, it might not be deemed to be independent under Delaware law. Rather, it
was concluded that TINTA's emphasis should be to ensure that the public
stockholders of TINTA received fair value for their TINTA Series A Stock in any
merger transaction with TCI. To this end, the Executive Committee authorized
TINTA's management to select and retain an independent financial advisor to
issue an opinion as to the fairness, from a financial point of view, to TINTA's
public stockholders of the exchange ratio proposed by TCI in its merger
proposal. The Executive Committee also approved the negotiation of a merger
agreement with TCI by TINTA's management and legal advisors.

                                       23
<PAGE>
 
      On July 15, 1998, Salomon Smith Barney was retained on behalf of the TINTA
Board to review the fairness, from a financial point of view, to the holders of
TINTA Common Stock (other than the TCI Holders) of the exchange ratio proposed
by TCI in its merger proposal.

     From July 15 through August 17, 1998, management of TINTA and TCI and their
respective legal advisors negotiated the terms of a merger agreement.  Officers
of TINTA met with Salomon Smith Barney during this period in connection with
Salomon Smith Barney's analysis of TCI's merger proposal, and provided estimates
and projections to Salomon Smith Barney.  Salomon Smith Barney also conducted
interviews with senior executives of Liberty during this period and was provided
certain information by such executives.  See "--Fairness Opinion."

     On August 17, 1998, a special meeting of the TINTA Board was held at the
New York offices of Baker & Botts to consider TCI's merger proposal.  At this
meeting, representatives of Salomon Smith Barney delivered a preliminary oral
presentation with respect to certain analyses performed by Salomon Smith Barney
in evaluating the fairness of the exchange ratio offered by TCI in its merger
proposal to the holders of TINTA Common Stock other than the TCI Holders.
Salomon Smith Barney's presentation included a discussion of a number of
analytical considerations, which are described in detail under "--Fairness
Opinion" below.  Salomon Smith Barney responded to questions and comments from
the TINTA Board.  Baker & Botts advised the TINTA Board as to the status of the
negotiations with TCI on a proposed merger agreement, made a presentation on the
material terms of the most recent draft of the merger agreement, and discussed
with the board the negotiations that had been held on the merger agreement to
date. TINTA's Delaware counsel, Richards, Layton & Finger, LLP ("RL&F") (which 
also represents TCI on a regular basis, including in connection with the merger 
proposal pursuant to a conflict waiver from TCI and TINTA), advised
the TINTA Board as to its fiduciary duties under Delaware law in its
deliberations on TCI's merger proposal and on the proposed merger agreement, and
discussed with the directors the allegations in, and status of, the Class Action
Lawsuits. The special meeting was then recessed to August 21.

     On August 20, 1998, RL&F and a representative of TCI conducted settlement
negotiations regarding the Class Action Lawsuits with Abbey, Gardy & Squitieri,
LLP, counsel for the plaintiffs (the "Plaintiff's Counsel"). After vigorous
negotiation on possible settlement alternatives, Plaintiff's Counsel agreed to
enter into a memorandum of understanding to settle the Class Action Lawsuits.
The settlement was based on TCI's agreement to change the merger agreement to
provide that if the 0.58 exchange ratio did not yield a value of at least $22.00
per share of TINTA Common Stock determined as of a date on or near the Effective
Time, then TCI must either (i) increase the exchange ratio to a level which
would provide that amount of LMG Series A Stock which yielded a value of $22.00
per share of TINTA Common Stock or (ii) terminate the Merger Agreement. TCI also
agreed not to take any action that would improperly manipulate the price of the
LMG Series A Stock during the period the value of such stock was to be
determined under the merger agreement.

     On August 21, 1998, the meeting of the TINTA Board was reconvened by
telephone conference call. Representatives of Baker & Botts and RL&F discussed
with the directors the revised terms of the proposed merger agreement and the
terms of the proposed settlement of the Class Action Lawsuits, including the
change to the merger agreement that would include the right of TCI, in the event
the exchange ratio yielded a value of less than $22.00 per share of TINTA Common
Stock, to implement the Minimum Value Adjustment or terminate the merger
agreement. Salomon Smith Barney updated its presentation of August 17, 1998 to
reflect market and other data as of August 18, 1998, and rendered its oral
opinion that, as of such date, the Exchange Ratio was fair, from a financial
point of view, to the holders of TINTA Common Stock other than the TCI Holders.
See "--Fairness Opinion." After discussion, the TINTA Board, by unanimous vote,
approved acceptance of TCI's revised merger proposal. On August 24, 1998, the
Merger Agreement was executed and TINTA issued a press release to that effect.

TINTA'S REASONS FOR THE MERGER; RECOMMENDATION OF THE TINTA BOARD

     The TINTA Board has unanimously approved the Merger Agreement, has
determined that it is advisable and fair and in the best interests of TINTA and
its stockholders other than TCI and its subsidiaries, and unanimously recommends
that holders of shares of TINTA Common Stock vote FOR the proposal to adopt the
Merger Agreement. 

                                       24
<PAGE>
 
In reaching its decision to approve the Merger Agreement and to recommend that
TINTA's stockholders vote to adopt the Merger Agreement, the TINTA Board
considered the following factors:

          (i)    The financial condition, competitive position and prospects of
     each of TINTA and the Liberty Media Group, and TINTA's future prospects as
     a stand-alone entity and on a combined basis with the Liberty Media Group.

          (ii)   The opinion of Salomon Smith Barney, as of August 21, 1998,
     that the Exchange Ratio was fair, from a financial point of view, to the
     holders of TINTA Common Stock other than the TCI Holders. A copy of Salomon
     Smith Barney's opinion is set forth in Appendix II to this Proxy
     Statement/Prospectus.

          (iii)  The Exchange Ratio included in the Merger Agreement ensured
     that each share of TINTA Common Stock would be exchanged in the Merger for
     a number of shares of LMG Series A Stock having a value of at least $22.00
     per share, which amount represents a 37.4% premium over the average trading
     price of the TINTA Series A Stock during the 20 trading day period ending
     immediately prior to the announcement of the AT&T Merger.

          (iv)   The expected difficulties TINTA would encounter in pursuing its
     growth strategy as a stand-alone company given its leverage at the holding
     company level, the capital needs of its subsidiaries and affiliates, its
     limited access to capital and its limited ability to access the cash flow
     of its less than majority-owned subsidiaries and affiliates.

          (v)    The increased liquidity of the LMG Series A Stock compared to
     the TINTA Series A Stock.

          (vi)   The ability of holders of TINTA Common Stock to continue to
     participate in the growth of TINTA's international assets through their
     ownership of LMG Series A Stock while limiting their exposure to the
     uncertainties of a business whose subsidiaries and affiliates operate
     almost exclusively outside the United States.  The TINTA Board also
     considered that the holders of TINTA Common Stock would have an opportunity
     to participate in the future performance of the other businesses and assets
     of the Liberty Media Group through their ownership of LMG Series A Stock,
     which they would receive through a tax-free exchange in the Merger.

     In view of the number of factors considered by the TINTA Board, the
disparate nature of these factors and each director's differing perspective, the
TINTA Board did not assign relative weights to the factors considered in its
conclusions.

     The TINTA Board concluded that it would be impracticable for TINTA to be
sold to or merged with a party other than TCI, as the participation of TCI in
any such transaction would be essential.  The TINTA Board also viewed TCI as the
best possible candidate to purchase all of TINTA, due to the Liberty Media
Group's international programming assets and TCI's familiarity with TINTA's
assets and business operations.  Accordingly, the TINTA Board did not solicit,
and did not authorize Salomon Smith Barney to solicit, alternative acquisition
proposals from third parties.  TCI refused to include in the Merger Agreement a
provision that would have required that the Merger Agreement be adopted by the
holders of a majority in voting power of the TINTA Common Stock not owned by TCI
or its subsidiaries.  Therefore, adoption of the Merger Agreement does not
require the affirmative vote of the holders of a majority in voting power of the
TINTA Common Stock not owned by TCI or its subsidiaries. The TINTA Board did not
form an independent committee of the TINTA Board to act solely on behalf of the
public stockholders of TINTA for the reasons discussed under "--Background"
above.

     For a discussion of the interests of certain members of the TINTA Board in
the Merger, see "--Interests of Certain Persons in the Merger."

FAIRNESS OPINION

     The TINTA Board retained Salomon Brothers Inc and Smith Barney Inc.,
collectively doing business as Salomon Smith Barney ("Salomon Smith Barney"),
pursuant to a letter agreement dated July 15, 1998 (the "Engagement Letter"), to
review the fairness, from a financial point of view, of the Exchange Ratio in
connection with the Merger to the holders of TINTA Common Stock other than the
TCI Holders.  Pursuant to the Engagement Letter, Salomon Smith Barney rendered
an opinion to the TINTA Board on August 21, 1998, to the effect that, based upon
the assumptions made, matters considered and limits of the review, as set forth
in such opinion, as of such date, the Exchange Ratio was fair, from a financial
point of view, to the holders of TINTA Common Stock other than the TCI Holders.

     The full text of Salomon Smith Barney's opinion dated August 21, 1998,
which sets forth the assumptions made, general procedures followed, matters
considered and limits on the review undertaken, is included as Appendix II to
this Proxy Statement/Prospectus.  The summary of Salomon Smith Barney's opinion
set forth below is qualified in its entirety by reference to the full text of
such opinion.  No limitations were imposed by TINTA or the TINTA Board with
respect to the investigations made or procedures followed by Salomon Smith
Barney in rendering its opinion. HOLDERS OF TINTA COMMON STOCK ARE URGED TO READ
SALOMON SMITH BARNEY'S OPINION IN ITS ENTIRETY.

     In connection with rendering its opinion, Salomon Smith Barney reviewed and
analyzed, among other things, the following:  (i) a draft as of August 21, 1998
of the Merger Agreement; (ii) certain publicly available information concerning
TINTA, including the Annual Reports on Form 10-K of TINTA for each of the years
in the three-year period ended December 31, 1997 and the Quarterly Reports on
Form 10-Q of TINTA for the quarters ended March 31, 1998 and June 30, 1998;
(iii) certain publicly available information concerning certain entities in
which TINTA holds a substantial equity interest (the "TINTA Portfolio
Companies"); (iv) certain other internal information, primarily financial in
nature, including projections, concerning the business, assets and operations of
TINTA and the TINTA Portfolio Companies furnished to Salomon Smith Barney by
TINTA for purposes of Salomon Smith Barney's analysis; (v) certain publicly
available information concerning the trading of, and the trading market for, the
TINTA Common Stock; (vi) certain publicly available information concerning the
Liberty Media Group, including separate information concerning the Liberty Media
Group contained in the Annual Reports on Form 10-K of TCI for each of the years
in the three-year period ended December 31, 1997 and the Quarterly Reports on
Form 10-Q of TCI for the quarters ended March 31, 1998 and June 30, 1998; (vii)
certain publicly available information concerning certain entities in which the
Liberty Media Group holds a substantial equity interest (the "Liberty Portfolio
Companies"); (viii) certain other internal information, primarily financial in
nature, including certain projected financial data, concerning the business,
assets and operations of the Liberty Media Group and the Liberty Portfolio
Companies furnished to Salomon Smith Barney by the Liberty Media Group for the
purposes of Salomon Smith Barney's analysis; (ix) the TCI Charter, including the
terms of the LMG Series A Stock set forth therein; and (x) certain publicly
available information concerning the trading of, and the trading market for, LMG
Series A Stock.  Salomon Smith Barney also considered such other information,
financial studies, analyses, investigations and financial, economic and market
criteria that it deemed relevant.  Salomon Smith Barney met with certain
officers and employees of TINTA, TCI and the Liberty Media Group to discuss the
foregoing, as well as other matters Salomon Smith Barney believed relevant to
its inquiry.

     In its review and analysis and in arriving at its opinion, Salomon Smith
Barney assumed and relied upon the accuracy and completeness of all of the
financial and other information provided to it or publicly available and neither
attempted independently to verify nor assumed responsibility for verifying any
of such information.  Salomon Smith Barney did not conduct a physical inspection
of any of the properties or facilities of TCI, TINTA, the Liberty Media Group,
any TINTA Portfolio Company or any Liberty Portfolio Company, nor did Salomon
Smith Barney make or obtain or assume any responsibility for making or obtaining
any independent evaluations or appraisals of any of such properties or
facilities.  With respect to projections, Salomon Smith Barney assumed that they
were reasonably prepared on bases reflecting the best currently available
estimates and judgments of the management of TINTA or the Liberty Media Group,
as the case may be, as to the future financial performance of TINTA and the
TINTA Portfolio Companies or the Liberty Media Group and the Liberty Portfolio
Companies, as the case may be.  Salomon Smith Barney expressed no view with
respect to such projections or the assumptions on which they were based. The
draft of the Merger 

                                       26
<PAGE>
 
Agreement reviewed by Salomon Smith Barney did not include the Minimum Value
Adjustment, and Salomon Smith Barney assumed that the definitive Merger
Agreement, when executed, would contain a provision incorporating the Minimum
Value Adjustment. In addition, except as described in the preceding sentence,
Salomon Smith Barney assumed that the definitive Merger Agreement, when
executed, would not contain any other terms or conditions that differed
materially from the draft of the Merger Agreement reviewed by Salomon Smith
Barney and that the Merger would be consummated in a timely manner and in
accordance with the terms of the Merger Agreement, without waiver of any of the
conditions precedent to the Merger contained in the Merger Agreement. For the
purposes of its analysis, Salomon Smith Barney understood and assumed that the
Merger will qualify as a tax-free reorganization for federal income tax
purposes. Salomon Smith Barney further understood and assumed that, following
consummation of the Merger, for purposes of the LMG Series A Stock, the Liberty
Media Group will be deemed to be the beneficial owner of approximately 15% of
the outstanding capital stock of TINTA.

     In conducting its analysis and arriving at its opinion, Salomon Smith
Barney considered such financial and other factors as it deemed appropriate
under the circumstances, including, among others, the following:  (i) the
historical and current financial position and results of operations of TINTA,
the Liberty Media Group, the TINTA Portfolio Companies and the Liberty Portfolio
Companies; (ii) the business prospects of TINTA, the Liberty Media Group, the
TINTA Portfolio Companies and the Liberty Portfolio Companies; (iii) the terms
of the LMG Series A Stock; and (iv) the historical and current market for the
TINTA Common Stock and the LMG Series A Stock.  Salomon Smith Barney also took
into account its assessment of general economic, market and financial conditions
as well as its experience in connection with similar transactions and securities
valuation generally.  Salomon Smith Barney's opinion necessarily was based upon
conditions as they existed and could be evaluated on the date thereof and
Salomon Smith Barney assumed no responsibility to update or revise its opinion
based upon circumstances or events occurring after the date thereof.

     Salomon Smith Barney was not asked to consider, and its opinion does not
address, the relative merits of the Merger as compared to any alternative
business strategy that might exist for TINTA.  Salomon Smith Barney understood
that TCI is a party to the AT&T Agreement, pursuant to which it is contemplated
that TCI will be acquired by AT&T through the AT&T Merger and holders of LMG
Series A Stock will receive shares of AT&T Liberty/Ventures Class A Stock in
exchange for LMG Series A Stock (the "AT&T Exchange").  Salomon Smith Barney was
not asked to consider, and its opinion does not address, the AT&T Merger or the
AT&T Exchange or the effect thereof on LMG Series A Stock or the effect, if any,
of any decision not to proceed with or consummate the AT&T Merger.  Salomon
Smith Barney further understood that it is contemplated that TCI Ventures Group
will merge with the Liberty Media Group following consummation of the Merger.
Salomon Smith Barney was not asked to consider for the purposes of its opinion,
and its opinion does not address, the Liberty Ventures/Combination or the effect
thereof on LMG Series A Stock or the effect, if any, of any decision not to
proceed with or consummate the Liberty/Ventures Combination.  In its analysis,
Salomon Smith Barney understood and took into account the fact that the TCI
Holders currently own, directly or indirectly, approximately 85% of the
outstanding TINTA Common Stock.  Salomon Smith Barney's opinion does not
constitute an opinion or imply any conclusion as to the likely trading range for
LMG Series A Stock following consummation of the Merger or the Liberty/Ventures
Combination or the likely trading range for AT&T Liberty/Ventures Class A Stock
following consummation of the AT&T Merger.  Salomon Smith Barney's opinion is,
in any event, limited to the fairness, from a financial point of view, of the
Exchange Ratio to the holders of TINTA Common Stock other than the TCI Holders,
and does not constitute a recommendation to any holder of TINTA Common Stock as
to how such holder should vote with respect to the Merger.

     Salomon Smith Barney made a preliminary presentation to the TINTA Board on
August 17, 1998, which it updated on August 21, 1998 in connection with
rendering its opinion, with respect to certain analyses performed by Salomon
Smith Barney in evaluating the Exchange Ratio.  The following is a summary of
such Salomon Smith Barney presentation.  The following quantitative information,
to the extent it is based on market data, is based on market data as it existed
at August 18, 1998, and is not necessarily indicative of current market
conditions.

     Sum of the Parts Analysis--Overview.  TINTA is a holding company, and the
Liberty Media Group includes a holding company, that holds primarily minority
equity investments in other entities which are not consolidated for 

                                       27
<PAGE>
 
accounting purposes. Accordingly, Salomon Smith Barney used a "sum of the parts"
analysis to value each of TINTA and the Liberty Media Group, which analysis
involved the valuation of each of such entity's investments separately and then
the aggregation and adjustment of those valuations to obtain a composite
valuation of such entity.

     Sum of the Parts Analysis--TINTA. Except as noted below with respect to TCI
Music, Inc. ("TCI Music"), Salomon Smith Barney calculated a value for each of
the investments held by TINTA in publicly-traded companies (Telewest, Flextech
and TCI Music) (the "TINTA Public Companies"), by multiplying the number of
shares of each such company held by TINTA by the average closing price per share
of each such company over the twenty trading-day period through August 18, 1998.
With respect to TCI Music, of which TINTA owns approximately 2.7 million shares,
such shares were valued at $8.00 per share, the price to be paid upon TINTA's
exercise of its put right associated with each such share, as TINTA management
indicated to Salomon Smith Barney its intent to exercise such put prior to the
Merger.  Based on this analysis, Salomon Smith Barney calculated an implied
total market value for TINTA's investments in the TINTA Public Companies of
$1.536 billion (the "TINTA Public Investment Value").  With respect to Telewest
and Flextech, in which TINTA holds equity stakes of approximately 20.9% and
36.8%, respectively, Salomon Smith Barney also performed the analysis applying a
5.0% discount to the market value of such investments to reflect, in Salomon
Smith Barney's judgment, the extent of the discount to market value that likely
would be incurred by TINTA in attempting to dispose of a large minority equity
stake in such companies.  Based on this adjusted market value analysis, Salomon
Smith Barney calculated an implied total market value for TINTA's investments in
the TINTA Public Companies of $1.460 billion (the "Adjusted TINTA Public
Investment Value").

     With respect to investments held by TINTA in entities that are not
publicly-traded (Cablevision S.A., Sky Latin America, Metropolis-Intercom S.A.,
Torneos y Competencias S.A., Jupiter Telecommunications Co., Ltd., Jupiter
Programming Co., Ltd., Fox Sports International, MultiThematiques, S.A., TCI
Cablevision of Puerto Rico, Inc., Bresnan International Partners (Poland), L.P.,
Princes Holdings Ltd., Videopole S.A. and The Premium Movie Partnership) (the
"TINTA Private Companies"), Salomon Smith Barney used a discounted cash flow
("DCF") analysis, in which an entity's value is estimated based on the sum of
the present value of projected free cash flows for a defined period plus the
present value of such entity's terminal value at the end of such period, to
determine a firm or enterprise value for each such entity.  Salomon Smith Barney
then subtracted such entity's total debt from such firm or enterprise value in
order to arrive at an equity value for such entity.  The resulting equity value
was then multiplied by TINTA's percentage ownership of such entity in order to
determine the value of TINTA's investment in such entity.  For TINTA Private
Companies that are holding companies with minority investments in other entities
(that is, those entities with structures comparable to that of TINTA), a similar
DCF analysis was done with respect to the investments held by such TINTA Private
Companies in order to determine a composite value for each of such TINTA Private
Companies.

     TINTA management provided Salomon Smith Barney with forecasts of free cash
flow for each of the TINTA Private Companies (and, if necessary for Salomon
Smith Barney's analysis and available, with forecasts for entities in which such
TINTA Private Company has made an equity investment).  Generally, free cash flow
forecasts were provided through fiscal 2007.  A terminal value for each such
entity was estimated by applying multiples to forecasted earnings before
interest, taxes, depreciation and amortization ("EBITDA") for the terminal year
(usually 2007). Multiples used to estimate terminal values ranged from 3.5x to
11.0x EBITDA, as deemed appropriate by Salomon Smith Barney after considering
the nature and location of the entity and its operations and businesses.  Such
free cash flow forecasts and terminal values were discounted using a range of
discount rates derived using the capital asset pricing model and adjusted to
reflect, as appropriate in Salomon Smith Barney's judgment, factors such as
political risk associated with the countries in which such entities operate or
hold investments and risks faced by businesses in comparable stages of maturity.
The discount rates used ranged from 13% to 18%.

     Based on its DCF analysis, Salomon Smith Barney calculated a range for the
implied total value of TINTA's investments in the TINTA Private Companies of
$1.595 billion to $1.986 billion (the "Private Company DCF Range"). Salomon
Smith Barney also performed the DCF analysis applying discounts ranging up to
30% to the value of TINTA's stake in each TINTA Private Company to reflect the
relative illiquidity of investments in privately-held entities and the fact that
TINTA does not have control or has only limited control over such entities.
Based on such adjusted DCF

                                       28
<PAGE>
 
analysis, Salomon Smith Barney calculated a range for the implied total value of
TINTA's investments in the TINTA Private Companies of $1.243 billion to $1.547
billion (the "Adjusted Private Company DCF Range").

     Salomon Smith Barney also used research reports published by equity
analysts during 1998 to value TINTA's stake in each of the TINTA Private
Companies. Research reports published by Salomon Smith Barney, Merrill Lynch &
Co. and CS First Boston were used for this purpose. For certain TINTA Private
Companies, analysts' estimates of the equity value of TINTA's investment in such
entity were available. If such estimates were not available, Salomon Smith
Barney used analysts' estimates of the firm or enterprise value of the relevant
TINTA Private Company, deducted the amount of such entity's debt based on
information provided by TINTA, and multiplied the resulting implied equity value
by TINTA's percentage ownership of such entity in order to determine an implied
value for TINTA's investment in such entity. Based on such analysts' estimates
and its analysis, Salomon Smith Barney calculated a range for the implied total
value of TINTA's investments in the TINTA Private Companies of $1.245 billion to
$1.566 billion (the "Analysts Private Company Range").

     Salomon Smith Barney derived implied equity values for TINTA (the "TINTA
Implied Equity Values") by (A) adding (i) the total value of TINTA's investments
in the TINTA Public Companies, (ii) the total value of TINTA's investments in
the TINTA Private Companies, (iii) the total value of certain other investments
held by TINTA (with an estimated total value of $75 million based on information
provided by TINTA), and (iv) TINTA's reported cash on hand as of March 31, 1998,
as adjusted to reflect certain subsequent events and the assumed exercise of
outstanding stock options (total value of $70 million), and (B) subtracting
TINTA's reported total debt as of March 31, 1998, as adjusted to reflect certain
subsequent events and the elimination of the debt of TCI Cablevision of Puerto
Rico, Inc. which was reflected in Salomon Smith Barney's valuation of that
company (total value of $345 million). Salomon Smith Barney computed implied
equity values per share of TINTA Common Stock by dividing the TINTA Implied
Equity Values by 117.9 million, the approximate total number of shares of TINTA
Common Stock outstanding as of June 30, 1998 (including for this purpose
restricted stock and shares underlying outstanding stock options). Using the
Private Company DCF Range and the TINTA Public Investment Value, Salomon Smith
Barney derived a range for the implied equity value per share of TINTA Common
Stock of $24.86 to $28.18. Using the Adjusted Private Company DCF Range and the
Adjusted TINTA Public Investment Value, Salomon Smith Barney derived a range for
the implied equity value per share of TINTA Common Stock of $21.24 to $23.81
(the "Adjusted TINTA DCF Range"). Using the Analysts Private Company Range and
the TINTA Public Investment Value, Salomon Smith Barney derived a range for the
implied equity value per share of TINTA Common Stock of $21.89 to $24.62 (the
"TINTA Analysts Range").

     Sum of the Parts Analysis--Liberty Media Group. Except as noted below with
respect to TCI Music, Salomon Smith Barney calculated a value for each of the
investments held by the Liberty Media Group in publicly-traded companies (Time
Warner Inc., USA Networks, Inc., TCI Music, United Video Satellite Group, Inc.,
Cablevision Systems Corp. and Cendant Corp.) (the "Liberty Public Companies") by
multiplying the number of shares of each such company held by the Liberty Media
Group by the average closing price per share of such company over the twenty
trading-day period through August 18, 1998. For purposes of this analysis, the
shares of TCI Music were valued at $1.75 per share, the price of such shares
prior to the announcement of the merger of TCI Music and DMX Inc. The value of
the Liberty Media Group's holdings of TCI Music was established by multiplying
such per share value by 77.6 million, the approximate number of shares the
Liberty Media Group would hold after giving effect to the exercise by holders
other than the Liberty Media Group of certain put rights associated with such
shares, and deducting the aggregate cost of the Liberty Media Group's obligation
to purchase shares of TCI Music not held by the Liberty Media Group at $8.00 per
share upon exercise of the put right associated with each such share of TCI
Music. Based on this analysis, Salomon Smith Barney calculated an implied total
market value for the Liberty Media Group's investments in the Liberty Public
Companies of $7.644 billion (the "Liberty Public Investment Value"). With
respect to Time Warner Inc., USA Networks, Inc. and United Video Satellite
Group, Inc., in which the Liberty Media Group holds equity stakes (adjusted for
announced but not yet consummated transactions involving such companies) of
10.0%, 21.2% and 16.0%, respectively, Salomon Smith Barney also performed the
analysis applying a 5.0% discount to the market value of such investments to
reflect, in Salomon Smith Barney's judgment, the extent of the discount to
market value that likely would be incurred by the Liberty Media Group in
attempting to dispose of a large minority equity stake in such companies. Based
on this adjusted market value analysis, Salomon Smith Barney calculated an
implied total

                                       29
<PAGE>
 
value for the Liberty Media Group's investments in the Liberty Public Companies
of $7.267 billion (the "Adjusted Liberty Public Investment Value").

     With respect to investments held by the Liberty Media Group in entities
that are not publicly-traded (Discovery Communications, Inc., QVC Inc., Encore
Media Group, Fox/Liberty Networks, Fox Kids Worldwide, Inc., BET Holdings, Inc.,
International Sports Programming, Odyssey, Court TV, E! Entertainment
Television) (the "Liberty Private Companies"), Salomon Smith Barney used
valuation estimates provided by the Liberty Media Group management (the "Liberty
Management Estimates"), rather than estimates based on DCF analysis, for each
Liberty Private Company, which estimates indicated that the total value of the
Liberty Media Group's investments in the Liberty Private Companies was $11.537
billion (the "Liberty Management Private Company Value").  Salomon Smith Barney
was provided with certain financial forecasts by Liberty Media Group management;
however, it was not provided with the forecasts that would be needed to perform
individual DCF analyses with respect to the Liberty Private Companies. Salomon
Smith Barney applied discounts to the Liberty Management Estimates of up to 30%
to reflect the relative illiquidity of investments in privately-held entities
and the fact that the Liberty Media Group does not have control or has limited
control over such entities.  As so adjusted, the Liberty Management Estimates
indicated that the total value of the Liberty Media Group's investments in the
Liberty Private Companies was $9.989 billion (the "Adjusted Liberty Management
Private Company Value").

     Salomon Smith Barney also used research reports published during 1998 by
equity analysts at Salomon Smith Barney, Merrill Lynch & Co., CS First Boston,
Donaldson, Lufkin & Jenrette and Lehman Brothers to value the Liberty Media
Group's stake in each of the Liberty Private Companies.  For certain of the
Liberty Private Companies, analysts' estimates of the equity value of the
Liberty Media Group's investment in such company were available.  If such
estimates were not available, Salomon Smith Barney used analysts' estimates of
the firm or enterprise value of such entity, deducted the amount of such
entity's debt based on information provided by the Liberty Media Group, and
multiplied the resulting implied equity value by the Liberty Media Group's
percentage ownership of such entity in order to determine an implied value for
the Liberty Media Group's investment in such entity.  Based on such analysts'
estimates, Salomon Smith Barney calculated a range for the total implied value
of the Liberty Media Group's investments in the Liberty Private Companies of
$6.130 billion to $8.712 billion (the "Liberty Analysts Private Company Range").

     Salomon Smith Barney derived implied equity values for the Liberty Media
Group (the "Liberty Implied Equity Values") by (A) adding (i) the total value of
the Liberty Media Group's investments in the Liberty Public Companies, (ii) the
total value of the Liberty Media Group's investments in the Liberty Private
Companies, (iii) the total value of certain other investments held by the
Liberty Media Group (with an estimated total value of $135 million based on
certain valuation methods selected by Salomon Smith Barney), and (iv) the
Liberty Media Group's reported cash on hand as of March 31, 1998, as adjusted to
reflect certain subsequent events and the assumed exercise of outstanding stock
options (total value of $(456) million), and (B) subtracting the Liberty Media
Group's reported total debt as of March 31, 1998, as adjusted to reflect certain
subsequent events, the addition of certain inter-company obligations and the
elimination of the debt of Encore Media Group and TCI Music, consolidated by the
Liberty Media Group, which debt was reflected in the valuation of Encore Media
Group and TCI Music, as the case may be (total value of $643 million).  Salomon
Smith Barney computed implied equity values per share of the LMG Series A Stock
by dividing the Liberty Implied Equity Values by 396.6 million, the approximate
total number of shares of LMG Stock outstanding as of June 30, 1998 (including
for this purpose shares underlying certain outstanding stock options,
convertible notes and convertible preferred stock of TCI).  Using the Liberty
Management Private Company Value and the Liberty Public Investment Value,
Salomon Smith Barney derived an implied equity value per share of LMG Series A
Stock of $45.60 (the "Liberty Management Value").  Using the Adjusted Liberty
Management Private Company Value and the Adjusted Liberty Public Investment
Value, Salomon Smith Barney derived an implied equity value per share of LMG
Series A Stock of $40.74 (the "Adjusted Liberty Management Value").  Using the
Liberty Analysts Private Company Range and the Liberty Public Investment Value,
Salomon Smith Barney derived a range for the implied equity value per share of
LMG Series A Stock of $31.96 to $38.47 (the "Liberty Analysts Range").

                                       30

     Sum of the Parts Analysis--Conclusions.  Salomon Smith Barney calculated
certain implied values for the Merger Consideration (the "Implied Merger
Consideration Values") by multiplying the Exchange Ratio by the following
historical and implied per share prices for LMG Series A Stock (the "LMG Series
A Per Share Values"): (i) the closing price immediately prior to the initial
announcement of the Merger, which resulted in an implied value for the Merger
Consideration of $24.11; (ii) the closing price as of August 18, 1998, which
resulted in an implied value for the Merger Consideration of $21.06; (iii) the
average closing price over the twenty consecutive trading days through August
18, 1998, which resulted in an implied value for the Merger Consideration of
$22.32; (iv) the Liberty Management Value, which resulted in an implied value
for the Merger Consideration of $26.45; (v) the Adjusted Liberty Management
Value, which resulted in an implied value for the Merger Consideration of
$23.63; (vi) the lower limit of the Liberty Analysts Range, which resulted in an
implied value for the Merger Consideration of $18.54; (vii) the upper limit of
the Liberty Analysts Range, which resulted in an implied value for the Merger
Consideration of $22.31; (viii) the lower limit of the range of prices (the
"Liberty Price Target Range") derived from twelve-month per share price targets
for LMG Series A Stock published in 1998 by analysts at Salomon Smith Barney,
Donaldson, Lufkin & Jenrette, Lehman Brothers, Merrill Lynch & Co., and Morgan
Stanley Dean Witter, which resulted in an implied value for the Merger
Consideration of $23.20; and (ix) the upper limit of the Liberty Price Target
Range, which resulted in an implied value for the Merger Consideration of
$30.45.  Salomon Smith Barney noted that in each case (other than cases which
resulted in an Implied Merger Consideration Value less than the Minimum Value),
the Implied Merger Consideration Value was within or above the $21.24 to $23.81
Adjusted TINTA DCF Range.  Salomon Smith Barney also noted that in each case
(other than cases which resulted in an Implied Merger Consideration Value less
than the Minimum Value) the Implied Merger Consideration Value was within or
above the $21.89 to $24.62 TINTA Analysts Range.

     Analysts' Price Targets for TINTA Common Stock.  Salomon Smith Barney
reviewed twelve-month per share price targets for TINTA Common Stock published
during 1998 by analysts at CS First Boston, Donaldson, Lufkin & Jenrette,
Goldman, Sachs & Co., and Merrill Lynch & Co., which ranged from $21.50 to
$26.50 (the "TINTA Price Target Range").  Salomon Smith Barney noted that each
Implied Merger Consideration Value (other than Implied Merger Consideration
Values less than the Minimum Value) was within or above such range.  Salomon
Smith Barney further noted that the twelve-month per share price targets are
estimates of the future per share value of TINTA and that, in order to place
such targets on a more comparable basis to the Implied Merger Consideration
Values, the TINTA Board could consider the present value of such twelve-month
per share price targets.

     Exchange Ratio Premium Analysis.  Salomon Smith Barney compared the Implied
Merger Consideration Values to certain historical and implied per share values
of TINTA Common Stock to determine whether the Exchange Ratio would result in a
premium to each such per share value of TINTA Common Stock and, if so, the
amount of each such premium.  In particular, Salomon Smith Barney compared the
Implied Merger Consideration Values to the following historical and implied
prices per share of TINTA Common Stock ("TINTA Per Share Values"): (i) the
closing price one day prior to the initial announcement of the Merger; (ii) the
closing price one month prior to the initial announcement of the Merger; (iii)
the closing price six months prior to the initial announcement of the Merger;
(iv) the average closing price over the twenty consecutive trading days through
August 18, 1998; (v) the average closing price over the twenty consecutive
trading days immediately prior to the initial announcement of the pending AT&T
Merger; (vi) the upper and lower limits of the TINTA Analysts Range; (vii) the
upper and lower limits of the Adjusted TINTA DCF Range; and (viii) the upper and
lower limits of TINTA Price Target Range.  Excluding Implied Merger
Consideration Values less than the Minimum Value, Salomon Smith Barney noted
that the implied discount/premium represented by the Exchange Ratio ranged from
a discount of 15.8% to a premium of 90.2%.  Salomon Smith Barney also noted that
relative to the closing price of TINTA Series A Stock one day prior, one month
prior and six months prior to the initial announcement of the Merger, the
implied premium represented by the Exchange Ratio based on the Implied Merger
Consideration Values (excluding those values less than the Minimum Value) ranged
from 2.0% to 83.8%.

     Minority Purchase Premium Analysis.  Salomon Smith Barney reviewed certain
publicly available information relating to 28 transactions, each announced in
1997 or 1998, in which an equity interest representing less than a majority of a
public entity's total equity was (or is to be) acquired by an existing majority
stockholder.  Salomon Smith Barney determined that in such transactions the
premiums (the "Minority Purchase Premiums") paid for such equity interests 

                                       31
<PAGE>
 
over the closing price per share as of the date one month prior to the initial
announcement of the relevant transaction ranged from 0.3% to 76.0%, with a
median of 25.6% and a mean of 25.8%. Salomon Smith Barney noted that, based on
the average closing price for LMG Series A Stock over the twenty consecutive
trading days through August 18, 1998, the Exchange Ratio represents a premium of
34.8% over the closing price per share of TINTA Series A Stock as of the date
one month prior to the initial announcement of the Merger, which percentage
premium is greater than the median and mean Minority Purchase Premiums.

     Implied Exchange Ratio Analysis.  Salomon Smith Barney calculated certain
implied exchange ratios by dividing each of the LMG Series A Per Share Values by
each of the TINTA Per Share Values.  Based on these calculations (excluding
those involving the LMG Series A Per Share Values that would result in an
Implied Merger Consideration Value below the Minimum Value), the implied
exchange ratio ranged from 0.305 to 0.689.  Salomon Smith Barney also noted that
when calculating the implied exchange ratio by dividing each of the LMG Series A
Per Share Values (excluding those LMG Series A Per Share Values that would
result in an Implied Merger Consideration Value below the Minimum Value) by the
closing price of TINTA Series A Stock one day prior, one month prior and six
months prior to the initial announcement of the Merger, the implied exchange
ratio ranged from 0.315 to 0.569. Salomon Smith Barney further noted that the
Exchange Ratio exceeds the upper limit of such range.

     Historical Exchange Ratio Analysis.  Salomon Smith Barney reviewed the
daily closing prices of TINTA Series A Stock and LMG Series A Stock during the
period from August 5, 1995 through August 18, 1998 and the historical implied
exchange ratios during such period, determined by dividing the closing price per
share of TINTA Series A Stock by the closing price per share of LMG Series A
Stock for each day during such period.  Salomon Smith Barney noted that during
such period the implied exchange ratio ranged from 0.45 to 2.25.  Salomon Smith
Barney further noted that for the period of May 14, 1998 through July 10, 1998
(the last trading day prior to the initial announcement of the Merger), the
implied exchange ratio ranged from 0.45 to 0.57 and that the Exchange Ratio
exceeds the upper limit of such range.

     Salomon Smith Barney informed the TINTA Board that, because of a lack of
sufficient precedent transaction data, a lack of publicly-traded entities deemed
comparable to TINTA or the Liberty Media Group by Salomon Smith Barney and the
fact that the operations of several of the TINTA Private Companies and Liberty
Private Companies are in the early stages of development and therefore have not
yet produced substantial earnings or cash flow, Salomon Smith Barney did not
deem it necessary or appropriate to perform two other valuation analyses
frequently performed in connection with the evaluation of the fairness from a
financial point of view of an acquisition of a publicly-held company.  In
particular, Salomon Smith Barney did not deem it necessary or appropriate to
calculate implied values for the TINTA Common Stock or the LMG Series A Stock
based on valuation multiples derived from analysis of financial, operating and
stock market information for comparable companies or analysis of other merger
and acquisition transactions.

     The foregoing summary does not purport to be a complete description of the
analyses performed by Salomon Smith Barney or of its presentations to the TINTA
Board.  The preparation of financial analyses and fairness opinions is a complex
process involving subjective judgments and is not necessarily susceptible to
partial analysis or summary description.  Salomon Smith Barney made no attempt
to assign specific weights to particular analyses or factors considered, but
rather made qualitative judgments as to the significance and relevance of the
analyses and factors considered.  Accordingly, Salomon Smith Barney believes
that its analyses (and the summary set forth above) must be considered as a
whole, and that selecting portions of such analyses and of the factors
considered by Salomon Smith Barney, without considering all of such analyses and
factors, could create a misleading or incomplete view of the processes
underlying the analyses conducted by Salomon Smith Barney and its opinion.  In
its analyses, Salomon Smith Barney made numerous assumptions with respect to
TINTA, the Liberty Media Group, TCI, industry performance, general business,
economic, market and financial conditions and other matters, many of which are
beyond the control of TINTA, the Liberty Media Group and TCI.  Any estimates
contained in Salomon Smith Barney's analyses are not necessarily indicative of
actual values or predictive of future results or values, which may be
significantly more or less favorable than those suggested by such analyses.
Estimates of values of companies do not purport to be appraisals or necessarily
to reflect the prices at which companies may actually be sold.  Because such
estimates are inherently subject 

                                       32
<PAGE>
 
to uncertainty, none of TINTA, the Liberty Media Group, TCI, the TINTA Board,
the Board of Directors of Liberty, the Board of Directors of TCI, Salomon Smith
Barney or any other person assumes responsibility if future results or actual
values differ materially from the estimates. Salomon Smith Barney's analyses
were prepared solely as part of Salomon Smith Barney's analysis of the fairness
of the Exchange Ratio and were provided to the TINTA Board in that connection.
The opinion of Salomon Smith Barney was one of the factors taken into
consideration by the TINTA Board in making its determination to approve the
Merger Agreement and the Merger.

     Salomon Smith Barney is an internationally recognized investment banking
firm engaged in, among other things, the valuation of businesses and their
securities in connection with mergers and acquisitions, restructurings,
leveraged buyouts, negotiated underwritings, competitive biddings, secondary
distributions of listed and unlisted securities, private placements and
valuations for estate, corporate and other purposes.  TINTA selected Salomon
Smith Barney to act as its financial advisor on the basis of Salomon Smith
Barney's international reputation and Salomon Smith Barney's familiarity with
TINTA, the Liberty Media Group and TCI.  Salomon Smith Barney or its affiliates
previously have rendered certain investment banking and financial advisory
services to TINTA, the Liberty Media Group, TCI, TCI Ventures Group and AT&T,
for which Salomon Smith Barney or such affiliates received customary
compensation. Salomon Smith Barney and its affiliates (including Travelers Group
Inc.) may have other business relationships with TINTA and TCI.  In addition, in
the ordinary course of business, Salomon Smith Barney may actively trade the
debt and equity securities of TINTA, TCI (including LMG Series A Stock) and AT&T
for its own account and for the accounts of customers and, accordingly, may at
any time hold a long or short position in such securities.

     Pursuant to the Engagement Letter, TINTA agreed, among other things, to pay
Salomon Smith Barney a fee in an amount of $500,000, payable upon delivery of
Salomon Smith Barney's opinion and whether or not the Merger is consummated.  In
addition, whether or not the Merger is consummated, TINTA has agreed, pursuant
to the Engagement Letter, to reimburse Salomon Smith Barney for all reasonable
fees and disbursements of Salomon Smith Barney's counsel and all of Salomon
Smith Barney's reasonable travel and other out-of-pocket expenses and to
indemnify Salomon Smith Barney against certain liabilities and expenses relating
to or arising out of its engagement, including certain liabilities under the
federal securities laws.

     As noted under the caption "THE MERGER--TINTA's Reasons for the Merger;
Recommendation of the TINTA Board," the fairness opinion of Salomon Smith Barney
was one of several factors considered by the TINTA Board in determining to
approve the Merger Agreement and the Merger.  Salomon Smith Barney was not
involved in the negotiation of the Exchange Ratio between TINTA and TCI and was
retained by TINTA for the purpose of reviewing the fairness of the Exchange
Ratio from a financial point of view.

TCI'S REASONS FOR THE MERGER

     TCI believes that the acquisition of the outstanding equity interests in
TINTA not already owned by TCI will benefit TCI and its stockholders.  In
reaching its decision to make the merger proposal and to enter into the Merger
Agreement, TCI considered its management's assessment of TINTA's existing
financial position, the market performance of the TINTA Series A Stock since the
IPO, industry and market conditions, and the following factors: (i) that the
combination of TINTA's programming and distribution assets and the Liberty Media
Group's programming interests would result in substantial synergies; (ii) that
as a wholly-owned subsidiary of TCI, TINTA would benefit from TCI's greater
liquidity and access to capital, thereby increasing TINTA's ability to satisfy
the capital requirements necessary for it to pursue its growth strategy; (iii)
that operating costs could be reduced through more efficient use of shared
personnel and the elimination of duplicate public company costs; and (iv) that
certain potential conflicts of interests between TINTA and the Liberty Media
Group relating to the growth of their respective programming businesses would be
eliminated.

INTERESTS OF CERTAIN PERSONS IN THE MERGER

     In considering the recommendation of the TINTA Board with respect to the
Merger, TINTA stockholders should be aware that certain members of TINTA's
management and the TINTA Board have certain interests in the Merger that are
different from, or in addition to, the interests of stockholders of TINTA
generally.  The TINTA Board was aware of these interests and considered them,
among other matters, in approving the Merger Agreement.

     TINTA Options and Stock Appreciation Rights.  As of August 1, 1998,
executive officers and directors of TINTA held options ("TINTA Options") to
purchase an aggregate of 1,715,000 shares of TINTA Series A Stock at various
exercise prices and subject to various vesting schedules.  The outstanding TINTA
Options either were granted under the Tele-Communications International, Inc.
1995 Stock Incentive Plan (the "TINTA 1995 Plan") or the 1996 Nonemployee
Director Stock Option Plan (the "TINTA 1996 Nonemployee Director Plan" and,
together with the TINTA 1995 Plan, the "TINTA Plans").  All of the TINTA Options
issued under the TINTA 1995 Plan were issued in tandem with stock appreciation
rights ("TINTA SARs") with respect to TINTA Series A Stock.  In the case of a
tandem option or stock appreciation right, the related stock appreciation right
or option, as the case may be, is considered to have been exercised to the
extent of the number of shares of TINTA Common Stock with respect to which such
related tandem option or stock appreciation right is exercised.

     At the Effective Time, pursuant to the Merger Agreement, each of the then
outstanding TINTA Options to purchase shares of TINTA Common Stock issued by
TINTA will, by virtue of the Merger, and without any further action on the part
of any holder thereof, be assumed by TCI and converted into an option (an
"Assumed Option") to purchase that number of whole shares of LMG Series A Stock
determined by multiplying the number of shares of TINTA Common Stock subject to
such TINTA Option at the Effective Time by the Exchange Ratio, rounded up to the
nearest whole number, at an exercise price per share of LMG Series A Stock equal
to the exercise price per share of such TINTA Option immediately prior to the
Effective Time divided by the Exchange Ratio, rounded down to the nearest whole
cent; provided, however, that in the case of any options that are "incentive
stock options" (as defined in Section 422 of the Code), the adjustment provided
for in this sentence will be and is intended to be effected in a manner which is
consistent with Section 424(a) of the Code.  The terms and conditions of each
Assumed Option will otherwise remain as set forth in the TINTA Option converted
into such Assumed Option.  TINTA SARs issued in tandem with TINTA Options will
be similarly modified.

     The following table indicates for each person who is an executive officer
or director of TINTA and who held TINTA Options (including TINTA Options issued
in tandem with TINTA SARs) at August 1, 1998, (a) the number of shares of TINTA
Series A Stock subject to such options and/or stock appreciation rights that
were vested at August 1, 1998, (b) the number of shares of TINTA Series A Stock
subject to such options and/or stock appreciation rights that were not vested at
such date, (c) the exercise price per share of TINTA Series A Stock of all such
options and/or stock appreciation rights (whether vested or unvested), (d) the
total number of shares of LMG Series A Stock that would be subject to such
options and/or stock appreciation rights immediately following the Effective
Time assuming that all such options and/or stock appreciation rights continue to
be outstanding immediately prior to the Effective Time and (e) the exercise or
base price per share of LMG Series A Stock of such options and/or stock
appreciation rights immediately following the Effective Time.  The TINTA Options
listed opposite the name of each person in the table below (including TINTA
Options issued in tandem with TINTA SARs) include all TINTA Options and TINTA
SARs granted to such person under incentive plans of TINTA or otherwise.

     TINTA Restricted Stock Awards.  As of August 1, 1998, executive officers
and directors of TINTA held restricted stock awards ("TINTA Restricted Stock
Awards") under the TINTA 1995 Plan representing the right to receive, upon
vesting, an aggregate of 175,000 shares of TINTA Series A Stock.  At the
Effective Time, pursuant to the Merger Agreement, each restricted share of TINTA
Common Stock granted pursuant to any TINTA Plan and each restricted share of
TINTA Common Stock issued pursuant to individual awards not granted pursuant to
any TINTA Plan will, by virtue of the Merger, and without any further action on
the part of any holder thereof, be converted into a number of restricted shares
of LMG Series A Stock at the Exchange Ratio, and will remain subject to the same
restrictions applicable to such restricted share of TINTA Common Stock
immediately prior to the Effective Time.  See "THE MERGER AGREEMENT--

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

     The following is a discussion of the material federal income tax
consequences that are expected to result to the stockholders of TINTA from the
Merger.  This discussion is based upon current provisions of the Code, Treasury
Regulations promulgated thereunder ("Regulations"), current administrative
rulings, judicial decisions and other applicable authorities in effect as of the
date hereof, all of which are subject to change, possibly with retroactive
effect. No ruling from the Internal Revenue Service ("IRS") has been sought with
respect to the Merger or the other transactions contemplated by this Proxy
Statement/Prospectus, and there can be no assurance that the IRS or a court will
not successfully challenge the conclusions reached below.  Furthermore,
legislative, judicial or administrative changes may occur, perhaps with
retroactive effect, which could affect the accuracy of the statements and
conclusions set forth herein as well as the tax consequences to the TINTA
stockholders.

     The discussion contained herein does not address all aspects of federal
income taxation that may be relevant to particular TINTA stockholders in light
of their personal investment or tax circumstances, or to certain types of
holders who may be subject to special treatment under the federal income tax
laws (including, without limitation, financial institutions, broker-dealers,
insurance companies, foreign persons, tax-exempt organizations, holders of stock
or options who received such property for compensatory purposes, and holders who
hold the TINTA Common Stock or will hold the LMG Series A Stock as part of a
straddle, hedge or conversion transaction).  In addition, this discussion is
limited to persons who hold the TINTA Common Stock and who will hold the LMG
Series A Stock as "capital assets" (generally, property held for investment)
within the meaning of Code section 1221.  This discussion does not address
state, local and foreign tax consequences.

     THE FEDERAL INCOME TAX CONSEQUENCES SET FORTH IN THIS SECTION ARE INCLUDED
HEREIN FOR GENERAL INFORMATION ONLY.  EACH TINTA STOCKHOLDER SHOULD CONSULT A
TAX ADVISOR AS TO THE PARTICULAR CONSEQUENCES OF THE MERGER THAT MAY APPLY TO
SUCH STOCKHOLDER, INCLUDING THE APPLICATION OF STATE, LOCAL AND FOREIGN TAX
LAWS, AND POSSIBLE CHANGES IN FEDERAL INCOME TAX LAW THAT MAY OCCUR AFTER THE
DATE OF THIS PROXY STATEMENT/PROSPECTUS.

     Opinions of Counsel.  In the opinions of Baker & Botts, counsel to TINTA,
and Sherman & Howard, counsel to TCI, (i) subject to the conditions and
limitations described in such opinions, the Merger will be treated for U.S.
federal income tax purposes as a reorganization within the meaning of Section
368(a) of the Code, no gain or loss will be recognized by TINTA as a result of
the Merger and no gain or loss will be recognized by TINTA stockholders who
exchange TINTA Common Stock for LMG Series A Stock in the Merger; and (ii) the
discussion set forth under the caption "Certain Federal Income Tax Consequences"
in this Proxy Statement/Prospectus describes the material federal income tax
consequences expected to result to the stockholders of TINTA from the Merger and
fairly  represents such counsel's opinions as to the federal income tax matters
discussed herein.  In addition, in the opinion of Sherman & Howard, no gain or
loss will be recognized by TCI or Merger Sub as a result of the Merger.  In
rendering such opinions, counsel have relied upon representations contained in
certificates of TINTA and TCI.  Consummation of the Merger is conditioned upon
the foregoing opinions of counsel not having been withdrawn as of the Closing
Date.

     Tax Consequences to Holders of TINTA Common Stock.  Under Section 354 of
the Code, a holder of TINTA Common Stock who receives only LMG Series A Stock in
exchange for his/her TINTA Common Stock in the Merger will not recognize gain or
loss for federal income tax purposes.  The holder will have a tax basis in the
LMG Series A Stock equal to the holder's tax basis in the TINTA Common Stock
exchanged therefor.  The holder's holding period for the LMG Series A Stock for
the purposes of determining long-term or short-term capital gain or loss upon
the subsequent disposition of the LMG Series A Stock will include the period of
time the holder held the TINTA Common Stock.

                                       36
<PAGE>
 
     A holder of TINTA Common Stock who receives cash in lieu of a fractional
share of LMG Series A Stock will generally recognize taxable gain or loss.  Such
gain or loss will be determined as if the holder had actually received the
fractional share of LMG Series A Stock to which the holder will be required to
allocate a portion of its tax basis in the TINTA Common Stock and then had such
fractional share redeemed for the cash received.  The difference between the
basis allocated to a fractional share in this hypothetical redemption and the
cash received will constitute the gain or loss. This gain or loss will generally
be capital gain or loss (assuming the TINTA Common Stock was held as a capital
asset) and long-term capital gain or loss if the TINTA Common Stock had been
held for more than one year.

     All holders of the TINTA Common Stock who receive LMG Series A Stock in the
Merger will be required to attach a statement to their federal income tax
returns for the year of the Merger which describes the facts of the Merger,
including the holder's tax basis in the TINTA Common Stock exchanged, and the
number of shares of LMG Series A Stock received in exchange for that TINTA
Common Stock.  The holders should also keep as part of their permanent records
information necessary to establish their tax basis in the LMG Series A Stock
received in the Merger.

CERTAIN CONSEQUENCES OF THE MERGER; OPERATIONS FOLLOWING THE MERGER

     General.  Upon consummation of the Merger, the present holders of TINTA
Common Stock (other than TCI) will cease to have any direct interest in TINTA or
its future earnings or growth.  TCI will own 100% of the equity interest of the
Surviving Corporation and will attribute 85% of such interest to the TCI
Ventures Group and 15% of such interest to the Liberty Media Group.
Accordingly, holders of TINTA Common Stock who receive LMG Series A Stock in the
Merger, by virtue of such receipt, may indirectly share in TINTA's future
earnings and growth through the interest in the Surviving Corporation attributed
to the Liberty Media Group, and may also share in the future earnings and growth
of the other assets and businesses of TCI attributed to the Liberty Media Group.
If the Liberty/Ventures Combination is consummated, 100% of the equity interest
of the Surviving Corporation will be attributed to the Liberty/Ventures Group.

     As a result of the Merger, TINTA will become a privately-held subsidiary of
TCI.  The TINTA Series A Stock will be removed from listing on the NASDAQ/NM,
and its registration under the Exchange Act will be terminated.

     It is expected that the business and operations of TINTA will be conducted
after the Merger substantially as they are currently being conducted.  However,
a number of existing intercompany agreements between TCI and TINTA, covering
such matters as lending arrangements, indemnification, the provision of
services, the use of the Tele-Communications name and registration rights, will
be terminated.  See "CERTAIN TRANSACTIONS BETWEEN TCI AND TINTA."  In addition,
after the Merger, TCI will continue to evaluate the business and operations of
TINTA (as well as those of its other subsidiaries) and take such other actions
as it deems appropriate under then existing circumstances.

     Except for the Merger and as otherwise described in this Proxy
Statement/Prospectus (including the documents incorporated by reference herein),
neither TCI nor TINTA has any specific plans or proposals that would result in
an extraordinary corporate transaction, such as a merger, reorganization,
liquidation, or sale of a material amount of assets of TINTA.

     Consequences to Holders of Debentures.  The Debentures were issued under an
Indenture dated as of February 7, 1996 (the "Indenture"), between TINTA, as
issuer, and The Bank of New York, as trustee.  The Debentures are currently
convertible, at the option of the holders thereof, into shares of TINTA Series A
Stock at a conversion price of $27.30 per share of TINTA Series A Stock
(equivalent to a conversion rate of 36.63 shares per $1,000 principal amount of
Debentures).  Following the Effective Time, the Debentures outstanding
immediately prior to the Effective Time will remain outstanding and will remain
obligations of TINTA as the surviving corporation in the Merger.  As a result of
the Merger, however, pursuant to the terms of the Indenture, the Debentures will
be exchangeable into the number of shares of LMG Series A Stock (and the amount
of cash in lieu of fractional shares thereof) that a holder of such Debentures
would have received if such holder had converted such Debentures into shares of
TINTA Series A Stock immediately prior to the Effective Time.  In addition, the
Indenture provides that, in the event of any "Change 

                                       37
<PAGE>
 
of Control" (as defined in the Indenture), each holder of Debentures will have
the right, at such holder's option and subject to the terms and conditions of
the Indenture (including the time periods prescribed thereby), to require TINTA
to purchase all or any portion (provided the principal amount is $1,000 or an
integral multiple thereof) of such holder's Debentures as of the date that is 35
business days after the occurrence of such Change of Control, at a cash price
equal to 100% of the principal amount of such Debentures or portion thereof
tendered, plus accrued and unpaid interest thereon to the purchase date.
Consummation of the Merger will constitute a "Change of Control" of TINTA within
the meaning of the Indenture and, accordingly, holders of Debentures will have
the right to require TINTA to repurchase such Debentures in accordance with the
terms of the Indenture.

ACCOUNTING TREATMENT

     The Merger will be accounted for by TCI as a "purchase" of a minority
interest, as such term is used under generally accepted accounting principles,
for accounting and financial reporting purposes.  Accordingly, the consideration
paid for the acquired TINTA shares will be allocated on a pro rata basis to the
assets and liabilities of TINTA based on their respective fair values.

CERTAIN LITIGATION

     Shortly after TCI's announcement on July 13, 1998 of the making of its
initial merger proposal to TINTA, three putative class actions captioned
Berkowitz v. Hindery, et al., ETB Mircon Ltd. v. Hindery, et. al. and Firth v.
Hindery, et al., respectively (collectively, the "Class Action Lawsuits"), were
filed by stockholders of TINTA in the Delaware Court of Chancery against TCI,
TINTA and the directors of TINTA.  The Class Action Lawsuits allege, among other
things, that the consideration offered in the initial merger proposal was
inadequate, that those defendants who are directors of TINTA have violated their
fiduciary duties to TINTA and its public stockholders and that TCI has violated
its alleged fiduciary duties as a majority stockholder of TINTA.  Each of the
Class Action Lawsuits seeks certification as a class action on behalf of all
stockholders of TINTA other than the defendants, and seeks to enjoin the
proposed acquisition of TINTA by TCI and/or recover damages.

     As a result of the pendency and prosecution of the Class Action Lawsuits,
plaintiffs' counsel and TCI's counsel conducted negotiations in an effort to
reach a settlement of the Class Action Lawsuits.  Those negotiations resulted in
plaintiffs' agreement in principle to settle the Class Action Lawsuits based
upon, among other things, TCI's willingness to include in the Merger Agreement a
provision that if the Merger is consummated, the Exchange Ratio would yield a
value of at least $22.00 per share of TINTA Common Stock. See "--Background."

     Prior to the signing of the Merger Agreement, counsel for plaintiffs and
defendants in the Class Action Lawsuits executed a memorandum of understanding
dated August 21, 1998 (the "MOU"), which set forth the parties' agreement-in-
principle regarding the terms of a settlement of the Class Action Lawsuits.
Subject to court approval and other conditions, the MOU provides for the full
settlement of any and all claims which have been or could have been made in the
Class Action Lawsuits, all of which will be released and discharged, based upon
and subject to, among other things: (i) a merger in which the holders of shares
of TINTA Common Stock (other than any such shares held by TINTA in its treasury
or owned of record by TCI or any subsidiary of TCI) will receive 0.58 of share
of LMG Series A Stock per share of TINTA Common Stock; provided, however, that
if the product of 0.58 and the LMG Market Price on the Closing Date is less than
$22.00, TCI must either (a) increase the exchange ratio to equal the quotient
(rounded upwards, if necessary, to the nearest one one-thousandth) obtained by
dividing $22.00 by such LMG Market Price or (b) terminate the Merger Agreement
(it being agreed that TCI may elect to terminate the Merger Agreement if the
product of 0.58 and the LMG Market Price is less than $22.00), (ii) TCI not
having taken any action with respect to the LMG Series A Stock in violation of
Regulation M of the Exchange Act, and (iii) plaintiffs' counsel having had the
opportunity to review preliminary shareholder disclosure materials relating to
the Merger, and to negotiate with defendants' counsel to resolve any issues
raised by plaintiffs' counsel concerning the adequacy of such disclosure
materials.

                                       38
<PAGE>
 
     The MOU also provides that the parties to the Class Action Lawsuits,
through their counsel, will use their best efforts to pursue the settlement of
the Class Action Lawsuits and will cooperate in preparing the papers necessary
to define, pursue, and effectuate the settlement of the Class Action Lawsuits.
Further, the parties to the Class Action Lawsuits agreed in the MOU to use their
best efforts to agree upon a formal stipulation of settlement to include, among
other things, the express provision that all defendants have denied and continue
to deny that they have committed or have threatened to commit any violations of
law or breaches of duty to anyone.  The MOU also provides that, subject to the
terms and conditions of the MOU and the terms and conditions of the formal
stipulation of settlement, TINTA will pay, on behalf of and for the benefit of
the TINTA director defendants in the Class Action Lawsuits, such fees and
expenses as may be awarded by the Delaware Court.  Further, TINTA has agreed in
the MOU to pay all reasonable costs and expenses incurred in providing notice of
the settlement to the members of the class.

     The MOU further provides that consummation of the settlement contemplated
thereby will be subject to (i) the completion of discovery by the plaintiffs;
(ii) the execution by the parties' counsel of a formal stipulation of settlement
(and such other documentation as may be required to obtain final court approval
of the settlement); (iii) the consummation of the Merger; (iv) final court
approval of the settlement (and the exhaustion of possible appeals, if any); (v)
the dismissal of the Class Action Lawsuits with prejudice and without awarding
costs to any party (except as provided in the MOU) and court entry of a final
order and judgment containing such release language as is negotiated by the
parties and contained in the stipulation of settlement; and (vi) the
determination by defendants in the Class Action Lawsuits that the dismissal of
the Class Action Lawsuits in accordance with the stipulation of settlement will
result in the release with prejudice of all claims asserted in the Class Action
Lawsuits.  The MOU also provides that it will be null and void and of no force
and effect if any of the conditions contained therein are not met or if
plaintiffs' counsel determines in good faith that, based on the discovery
contemplated by the MOU, the proposed settlement is not fair, reasonable and
adequate.

     Plaintiffs' counsel are conducting their confirmatory discovery and the 
parties to the Class Action Lawsuits are preparing the formal stipulation of
settlement for court approval.  It is a condition to the respective obligations
of TCI and TINTA to consummate the Merger that there be no effective injunction
or similar order preventing consummation of the transactions contemplated by the
Merger Agreement as provided therein or permitting such consummation only
subject to any condition or restriction that has or would have a material
adverse effect on TINTA.  See "THE MERGER AGREEMENT--Conditions to the Merger."

ABSENCE OF APPRAISAL RIGHTS

     Under the DGCL, dissenters' appraisal rights are not available for the
shares of any class or series of stock, (A) which, at the record date fixed to
determine the stockholders entitled to receive notice of and to vote at the
meeting of stockholders to act upon the merger agreement, were designated as a
national market system security on an interdealer quotation system by the
National Association of Securities Dealers, Inc. ("NASD") and (B) the holders of
which shares are not required to accept in exchange therefor anything other than
shares of stock of another corporation, which shares will be designated as a
national market system security on an interdealer quotation system by the NASD,
and cash in lieu of fractional shares.  Accordingly, holders of TINTA Series A
Stock are not entitled to dissenters' appraisal rights in connection with the
Merger since (a) at the Record Date, the TINTA Series A Stock was listed on the
NASDAQ/NM and (b) in the Merger, holders of TINTA Common Stock will receive only
LMG Series A Stock, which will be listed on the NASDAQ/NM, and cash in lieu of
fractional shares thereof.

     As of the Record Date, there were no outstanding shares of TINTA Series B
Stock, other than the shares of TINTA Series B Stock held by TCI, all of which
will be canceled in the Merger.

CERTAIN TRANSACTIONS BETWEEN TCI AND TINTA

     Other than the Merger Agreement and the related transactions described in
this Proxy Statement/Prospectus or in a document incorporated herein by
reference, there has not been during the last two full fiscal years of TINTA any
material contract, arrangement, understanding, relationship, negotiation or
transaction between TINTA or its affiliates 

                                       39

and TCI or its affiliates concerning a merger, consolidation or acquisition,
tender offer or other acquisition of securities, election of directors, or a
sale or transfer of a material amount of assets. See "CERTAIN TRANSACTIONS

                             THE MERGER AGREEMENT

     The following description of the Merger Agreement is qualified in its
entirety by reference to the complete text of the Merger Agreement, which is
incorporated by reference herein and a copy of which (exclusive of exhibits and
schedules) is annexed to this Proxy Statement/Prospectus as Appendix I.

GENERAL; EFFECTIVE TIME

     The Merger Agreement provides that, upon the terms and subject to the
conditions of the Merger Agreement, Merger Sub will merge with and into TINTA,
with TINTA being the Surviving Corporation.  In the Merger, which will become
effective on the date and at the time that the Certificate of Merger is accepted
for filing by the Delaware Secretary of State in accordance with the applicable
provisions of the DGCL (or such later date and time as may be agreed to by TCI
and TINTA and specified in the Certificate of Merger), stockholders of TINTA
will receive the consideration described below under "--Consideration to be
Received in the Merger."  Such filing is expected to take place as soon as
practicable after the closing of the transactions contemplated by the Merger
Agreement.  The Merger will have the effects set forth in the DGCL (including,
without limitation, Sections 259, 260 and 261 thereof).

     As a result of the Merger, TINTA will become a wholly-owned subsidiary of
TCI.  The Merger Agreement provides that (i) the TINTA Charter will be amended
pursuant to the Certificate of Merger to be identical to the certificate of
incorporation of Merger Sub in effect immediately prior to the Effective Time,
except to indicate that the name of the Surviving Corporation will be "Tele-
Communications International, Inc.," and such TINTA Charter as so amended will
be the certificate of incorporation of the Surviving Corporation until
thereafter amended in accordance with the terms thereof and the DGCL, (ii)
TINTA's Bylaws will be amended as of the Effective Time to be identical to the
bylaws of Merger Sub in effect immediately prior to the Effective Time (except
to the extent required to reflect that the name of the Surviving Corporation
will be "Tele-Communications International, Inc.") and, in such amended form,
will be the bylaws of the Surviving Corporation until thereafter amended in
accordance with the terms thereof, the certificate of incorporation of the
Surviving Corporation and the DGCL, and (iii) the directors of Merger Sub and
the officers of TINTA at the Effective Time will, from and after the Effective
Time, be the directors and officers of the Surviving Corporation until their
respective successors are duly elected or appointed and qualified in accordance
with the certificate of incorporation and bylaws of the Surviving Corporation,
or as otherwise provided by applicable law.

CONSIDERATION TO BE RECEIVED IN THE MERGER

     TINTA Common Stock.  Pursuant to the Merger Agreement, at the Effective
Time, each share of TINTA Common Stock outstanding immediately prior to the
Effective Time (other than any such shares held by TINTA in its treasury or
owned of record by TCI or any subsidiary of TCI, all of which will be canceled)
will be converted in the Merger into the right to receive 0.58 of a share of LMG
Series A Stock.  Notwithstanding the foregoing, if the product of 0.58 and the
LMG Market Price on the Closing Date is less than $22.00, TCI must either (i)
increase the exchange ratio to equal the quotient (rounded upwards, if
necessary, to the nearest one one-thousandth) obtained by dividing 

                                       40
<PAGE>
 
$22.00 by such LMG Market Price or (ii) terminate the Merger Agreement. See
"DESCRIPTION OF TCI CAPITAL STOCK." If any holder of TINTA Common Stock would be
entitled to receive a number of shares of LMG Series A Stock that includes a
fraction, then in lieu of a fractional share, such holder will be entitled to
receive cash in an amount determined by multiplying such fraction by the current
market value of a whole share of LMG Series A Stock and rounding the product to
the nearest whole cent. The "current market value" of a share of LMG Series A
Stock means, for this purpose, the average of the last reported sale prices (or,
if on any day no sale price is reported, the average of the quoted high and low
bid prices on such day) of a share of LMG Series A Stock on the NASDAQ/NM (or,
if the LMG Series A Stock is not traded on the NASDAQ/NM, on the principal stock
exchange on which such stock is traded) for the period of five consecutive
trading days ending on and including the last full trading day preceding the
Closing Date.

     TINTA Options, Stock Appreciation Rights and Restricted Stock Awards.  For
a description of the treatment of TINTA Options, TINTA SARs and TINTA Restricted
Stock Awards under the Merger Agreement, see "THE MERGER--Interests of Certain
Persons in the Merger."

     Merger Sub Capital Stock.  At the Effective Time, each share of capital
stock of Merger Sub outstanding immediately prior to the Effective Time will be
converted into one share of the common stock of the Surviving Corporation.  As a
result, the Surviving Corporation will be a wholly-owned subsidiary of TCI
immediately after the Effective Time.

     Certain Adjustments.  If, prior to the Effective Time, the LMG Series A
Stock is recapitalized or reclassified or TCI effects any stock dividend, stock
split, or reverse stock split of LMG Series A Stock or otherwise effects any
transaction that changes the LMG Series A Stock into any other securities
(including securities of another corporation, including securities of AT&T) or
any dividend or distribution is made on the LMG Series A Stock (or such other
securities), then the shares of LMG Series A Stock to be delivered in the Merger
to the holders of TINTA Common Stock will be appropriately and equitably
adjusted to the kind and amount of shares of stock and other securities and
property which the holders of such shares of LMG Series A Stock would have been
entitled to receive had such shares been issued and outstanding as of the record
date for determining stockholders entitled to participate in such corporate
event.

     Exchange of Shares.  Promptly after the Effective Time, transmittal letters
will be mailed to each holder of record of shares of TINTA Common Stock to be
used in forwarding his or her certificates evidencing such shares for surrender
and exchange for certificates evidencing the shares of LMG Series A Stock to
which he or she has become entitled and, if applicable, cash in lieu of a
fractional share of LMG Series A Stock.  After receipt of such transmittal
letter, each holder of certificates formerly representing TINTA Common Stock
should surrender such certificates to The Bank of New York, as exchange agent
(the "Exchange Agent"), and each such holder will receive in exchange therefor
certificates evidencing the number of whole shares of LMG Series A Stock to
which he or she is entitled and a check for any cash that may be payable in lieu
of a fractional share of LMG Series A Stock.  Such transmittal letters will be
accompanied by instructions specifying other details of the exchange.

     STOCKHOLDERS SHOULD NOT SEND IN THEIR CERTIFICATES UNTIL THEY RECEIVE A
TRANSMITTAL LETTER.

     After the Effective Time, each certificate evidencing TINTA Common Stock
(other than certificates evidencing shares held directly by TINTA in its
treasury or shares owned of record by TCI or any subsidiary of TCI, all of which
will be canceled), until so surrendered and exchanged, will be deemed, for all
purposes, to evidence only the right to receive the number of shares of LMG
Series A Stock that the holder of such certificate is entitled to receive and
the right to receive any cash payment in lieu of a fractional share of LMG
Series A Stock.  The holder of such unexchanged certificate will not be entitled
to receive any dividends or other distributions payable by TCI until the
certificate is surrendered.  Subject to applicable laws, such dividends and
distributions, if any, will be accumulated and, at the time of such surrender,
all such unpaid dividends and distributions, together with any cash payment in
lieu of a fractional share of LMG Series A Stock, will be paid, without
interest.

                                       41

in the interest rate or the principal amount of such indebtedness) and (d) the
incurrence of any new indebtedness, or the amendment or refinancing of any
existing indebtedness (whether or not permitted by clause (c)), if such
indebtedness would be prepayable in full at the Effective Time without material
restrictions (other than customary prepayment penalties and premiums that, in
the case of any refinancing, are no greater than those contained in the
indebtedness being refinanced).

     Certain Covenants by TCI.    Pursuant to the Merger Agreement, TCI has
agreed, in its capacity as a beneficial owner of TINTA Common Stock, to cause
the TINTA Common Stock beneficially owned by TCI to be voted at the Meeting in
favor of the proposal to adopt the Merger Agreement.

     In addition, TCI has agreed, if the AT&T Merger becomes effective prior to
the Effective Time, to cause AT&T to take such action, including executing such
documents and instruments, as may be necessary or desirable in order for (i) the
holders of TINTA Series A Stock to receive, at the Effective Time and in
accordance with the Merger Agreement, shares of AT&T Liberty/Ventures Class A
Stock, (ii) the holders of Assumed Options to receive, upon exercise of such
options and in accordance with the Merger Agreement, shares of AT&T
Liberty/Ventures Class A Stock, (iii) the holders of Debentures to receive, upon
conversion of and in accordance with the terms of such debentures, shares of
AT&T Liberty/Ventures Class A Stock and (iv) all other provisions contained in
the Merger Agreement that are intended to be performed by, and binding upon, the
issuer of the LMG Series A Stock to be performed by, and binding upon, AT&T as
the issuer of the AT&T Liberty/Ventures Class A Stock.

LISTING ON NASDAQ/NM

     The LMG Series A Stock is listed on the NASDAQ/NM.  TCI has agreed to use
its reasonable best efforts to cause the shares of LMG Series A Stock to be
issued pursuant to the Merger Agreement and upon exercise of the Assumed Options
to be authorized for listing on the NASDAQ/NM (or on the stock exchange which,
at the Effective Time, is the principal market for the LMG Series A Stock),
subject to official notice of issuance.  The obligation of TINTA to consummate
the transactions contemplated by the Merger Agreement is subject to the
authorization for listing on the NASDAQ/NM of such shares, subject only to
official notice of issuance.  See "--Conditions to the Merger."

INDEMNIFICATION

     The Merger Agreement provides that, from and after the Effective Time, TCI
will indemnify, defend and hold harmless the present and former directors,
officers, employees or agents of TINTA and any of its subsidiaries, and any
person who is or was serving at the request of TINTA as a director, officer,
employee or agent of another entity (collectively, the "Indemnified Parties")
against (i) all losses, claims, damages, costs, expenses (including fees and
expenses of counsel properly retained by an Indemnified Party under the Merger
Agreement), liabilities or judgments or amounts that are paid in settlement with
the approval of TCI (which approval shall not be unreasonably withheld) of or in
connection with any claim, action, suit, proceeding or investigation based in
whole or in part on or arising in whole or in part out of the fact that such
person was at any time prior to the Effective Time a director, officer, employee
or agent of TINTA, whether pertaining to any matter existing or occurring at or
prior to the Effective Time and whether asserted or claimed prior to, at or
after the Effective Time ("Indemnified Liabilities") and (ii) all Indemnified
Liabilities based in whole or in part on, or arising in whole or in part out of,
or pertaining to the Merger Agreement or the transactions contemplated thereby
(and TCI shall pay expenses in advance of the final disposition of any such
action, suit, proceeding or investigation to each Indemnified Party (including
fees and expenses of counsel properly retained by an Indemnified Party under the
Merger Agreement), to the full extent permitted by law upon receipt of the
undertaking contemplated by Section 145(e) of the DGCL), in each case to the
full extent that (x) a corporation is permitted under Delaware law to indemnify
or advance expenses to its own directors, officers, employees or agents, as the
case may be, (y) such Indemnified Party would have been entitled to be
indemnified by TINTA, if such Indemnified Party was a director, officer,
employee or agent of TINTA, with respect to the Indemnified Liabilities in
question under the TINTA Charter and TINTA's Bylaws as in effect on January 1,
1998 and under any indemnification agreement with 

                                       44
<PAGE>
 
TINTA in a form disclosed to TCI prior to the date of the Merger Agreement and
(z) such indemnification otherwise is permitted by applicable law.

TERMINATION, AMENDMENT AND WAIVER

     The Merger Agreement may be terminated and the Merger abandoned at any time
prior to the Effective Time, whether before or after adoption of the Merger
Agreement by the stockholders of TINTA, by (a) mutual consent of TINTA and TCI;
(b) either TINTA, on the one hand, or TCI and Merger Sub, on the other hand, if
(i) the Merger has not been consummated before January 31, 1999, unless such
failure is due to the failure of the party seeking to terminate the Merger
Agreement to perform any of its obligations thereunder, (ii) there has been a
material breach of any representation, warranty, covenant or agreement on the
part of the other party (or by Merger Sub, if the party seeking to terminate the
Merger Agreement is TINTA) contained in the Merger Agreement and such breach is
incapable of being cured, (iii) any court of competent jurisdiction or other
competent governmental authority has issued an order, decree or ruling or taken
any other action permanently restraining, enjoining or otherwise prohibiting the
Merger and such action has become final and nonappealable, or (iv) the required
adoption of the Merger Agreement by the stockholders of TINTA has not been duly
obtained, provided the terminating party has complied with its obligations
contained in the Merger Agreement regarding the Meeting and applicable SEC
filings; or (c) TCI, if (i) the product of 0.58 and the LMG Market Price on the
Closing Date is less than $22.00, or (ii) the TINTA Board has withdrawn or
modified in any manner adverse to TCI its recommendation to TINTA stockholders
regarding the adoption of the Merger Agreement.

     In the event of termination of the Merger Agreement by either TINTA or TCI
as provided above, the Merger Agreement will become void and there will be no
liability or obligation on the part of TCI, Merger Sub, TINTA or their
respective affiliates, stockholders, officers, directors, agents or
representatives (other than under certain specified provisions of the Merger
Agreement which will survive the termination thereof and other than to the
extent such termination results from the wilful breach by TCI, Merger Sub or
TINTA of any of its respective representations, warranties, covenants or
agreements contained in the Merger Agreement).

     TINTA and TCI may amend the Merger Agreement, by action taken or authorized
by their respective boards of directors, at any time prior to the Effective
Time, either before or after adoption by the stockholders of TINTA of the Merger
Agreement, except that after such adoption by the stockholders of TINTA, no
amendment may be made which by law requires further approval by such
stockholders without such further approval.  At any time prior to the Effective
Time, either TINTA or TCI, by action taken or authorized by such party's board
of directors, may, to the extent legally allowed, extend the time specified in
the Merger Agreement for the performance of any of the obligations of the other
party, waive any inaccuracies in the representations and warranties of the other
party contained in the Merger Agreement or in any document delivered pursuant
thereto, waive compliance by the other party with any of the agreements or
covenants of such other party contained in the Merger Agreement or waive any
condition to such waiving party's obligation to consummate the transactions
contemplated by, or other obligations under, the Merger Agreement.

ASSIGNMENT

     The Merger Agreement and all the rights, benefits and obligations under the
Merger Agreement will be assignable to and binding upon, and inure to the
benefit of and be enforceable by, any successor of TCI pursuant to the AT&T
Merger.  Except as otherwise provided in the preceding sentence, neither the
Merger Agreement nor any of the rights, benefits or obligations thereunder may
be assigned by any party without the prior written consent of the other party.
Subject to the preceding sentence, the Merger Agreement will be binding upon,
inure to the benefit of and be enforceable by the parties and their respective
successors and assigns.

CERTAIN RESTRICTIONS ON RESALE OF LMG SERIES A STOCK

     All shares of LMG Series A Stock received by TINTA stockholders in the
Merger will be registered under the Securities Act and freely transferable under
the federal securities laws, except that any such shares received by persons who
are deemed "affiliates" (as such term is defined under the Securities Act) of
TINTA prior to the Merger may be 

                                       45
<PAGE>
 
resold by them only in transactions permitted by the resale provisions of Rule
145 under the Securities Act (or Rule 144 in the case of such persons who become
affiliates of TCI) or as otherwise permitted under the Securities Act. Persons
who may be deemed to be affiliates of TINTA or TCI generally include individuals
or entities that control, are controlled by, or are under common control with
such party and may include certain officers and directors of such party as well
as principal stockholders of such party. The Merger Agreement requires TINTA to
use reasonable efforts to cause each of its affiliates to execute a written
agreement to the effect that such person will not offer or sell or otherwise
dispose of any of the shares of LMG Series A Stock issued to such person in or
pursuant to the Merger in violation of the Securities Act or the rules and
regulations promulgated by the SEC thereunder.

EXPENSES

     If the Merger Agreement is terminated prior to the Effective Time, TCI is
required to reimburse TINTA for all out-of-pocket costs and expenses incurred in
connection with the transactions contemplated by the Merger Agreement and all
costs and expenses incurred or otherwise owed by TINTA pursuant to the Merger
Agreement, provided that such termination is not the result of a material wilful
breach by TINTA of its covenants or agreements contained in the Merger Agreement
or the representations and warranties made by TINTA in the Merger Agreement.
Except as otherwise provided in the preceding sentence, whether or not the
Merger is consummated, each party will pay its own costs and expenses incurred
in connection with the Merger Agreement and the transactions contemplated
thereby, except that the aggregate expenses incurred in connection with the
printing and mailing of this Proxy Statement/Prospectus and the Registration
Statement will be borne 90% by TCI and 10% by TINTA.


                  CERTAIN TRANSACTIONS BETWEEN TCI AND TINTA

TRANSACTIONS WITH TCI AND OTHERS

     Relationship with TCI.  As of the Record Date, TCI beneficially owned
[86,250,000] shares of TINTA Series A Stock and [11,700,000] shares of TINTA
Series B Stock which, at such date, collectively represented approximately [92]%
of the total voting power of the outstanding shares of TINTA Common Stock.
Consequently, TCI has significant influence over the policies and affairs of
TINTA and is in a position to determine the outcome of corporate actions
requiring stockholder approval, including the election of directors, the
adoption of amendments to the TINTA Charter and the approval of mergers
(including the Merger) and the sale of all or substantially all of TINTA's
assets.

     TCI formed TINTA during the fourth quarter of 1994 and the first quarter of
1995 through the contribution to TINTA of substantially all of TCI's
international cable television and telephony assets and certain of TCI's
international programming assets.  The international programming assets that TCI
did not contribute to TINTA remained in two of TCI's other subsidiaries, Liberty
and TCIC.  The international programming assets that remained with Liberty were
those that were either (i) devoted to foreign sports programming or (ii) owned
directly or indirectly (in whole or in part) by U.S.-based programming companies
in which Liberty had an interest.  During 1996, Liberty contributed its
interests in foreign sports programming to Liberty/TINTA LLC ("Liberty/TINTA"),
a limited liability company owned in equal parts by subsidiaries of TINTA and
Liberty.  Liberty/TINTA then contributed such assets to a newly formed sports
programming venture with The News Corporation Limited.

     In connection with the formation of the TCI Ventures Group, TCI concluded
an exchange offer with its stockholders on September 10, 1997, whereby TCI
exchanged (i) shares of TCIVG Series A Stock for shares of TCI Group Series A
Stock, and (ii) shares of TCIVG Series B Stock for shares of TCI Group Series B
Stock.  The businesses and assets attributed to the TCI Ventures Group include
TCI's current equity interest in TINTA and substantially all of TCI's non-cable
and non-programming domestic assets.  With the formation of the TCI Ventures
Group, TCI assigned to TCI Ventures Group, L.L.C., various agreements, rights
and obligations related to TCI's assets attributed to the TCI Ventures Group,
including all of TCI's current equity interest in TINTA and certain financial
obligations.  See "--Credit Facility."  Upon consummation of the Merger, TCI
will attribute to the Liberty Media Group and the TCI Ventures Group 15% and
85%, respectively, of TCI's 100% equity interest in TINTA.

                                       46
<PAGE>
 
     In August 1998, Liberty purchased from TINTA 2,710,406 shares of Series A
Common Stock of TCI Music, a subsidiary of TCI, for a cash payment of
$21,683,248 ($8.00 per share).  Such purchase was made pursuant to TINTA's
exercise of a right granted to TINTA and all other stockholders of DMX Inc.
("DMX") in July 1997 when DMX was acquired by TCI Music through a merger in
which stockholders of DMX received 0.25 of a share of Series A Common Stock of
TCI Music for each share of DMX common stock.  Each share of Series A Common
Stock of TCI Music issued in that transaction was paired with a nondetachable
right (a "Right") to require TCI to purchase such share for $8.00 in cash or TCI
Group Series A Stock.  The Rights were exercisable for a 30 day period,
beginning July 13, 1998.  Liberty, which assumed TCI's obligations with respect
to the Rights in July 1997, elected to pay cash in satisfaction of all exercised
Rights.

     Credit Facility.  TINTA and TCI entered into a subordinated revolving
credit facility (the "Credit Facility"), effective April 25, 1995, which
provides for loans from TCI to TINTA in an aggregate principal amount at any
time outstanding of up to $200 million.  As of September 10, 1997, TCI assigned
all of its rights, interests and obligations in and to the Credit Facility to
TCI Ventures Group, L.L.C.  At the time of such assignment no borrowings were
outstanding under the Credit Facility.  In connection with the assignment, the
parties agreed to extend the maturity date of the Credit Facility to September
10, 2002, at which time all borrowings under the Credit Facility, together with
all accrued interest thereon, will be payable.  In addition, the parties reduced
the interest rate on the Credit Facility from 13% to 10% per annum.  Prior to
such maturity date, borrowings repaid by TINTA under the Credit Facility will be
available for re-borrowing, subject to certain conditions to borrowing.  TINTA
is required to pay an annual facility fee in an amount equal to .375% of the
unused borrowing availability under the Credit Facility.  At August 31, 1998,
approximately $6,658,000 (including accrued interest) was outstanding under the
Credit Facility.

     Other Agreements.  TCI and TINTA are parties to a number of intercompany
agreements covering matters such as lending arrangements, indemnification, the
provision of services, tax sharing, the use of the Tele-Communications name and
registration rights.  TCI also provides certain administrative, financial,
legal, treasury, accounting, tax and other services to TINTA and makes available
certain of its employee benefit plans to TINTA's employees.  It is expected that
following consummation of the Merger, all such existing arrangements, other than
tax sharing arrangements, will be terminated.

TRANSACTIONS WITH MANAGEMENT

     Consulting Agreement with Mr. Vierra.  Effective January 1, 1998, TCI
entered into a five year consulting agreement with Fred A. Vierra, a director
and Vice Chairman of the Board of TINTA and, until January 1998, Chief Executive
Officer of TINTA.  The consulting agreement provides for Mr. Vierra to provide
consulting services to TCI on the allocation of TCI's resources and other
matters generally and with respect to the international operations of TCI in
particular.  Mr. Vierra is not required to provide more than 700 hours per year
in such consulting services.  For such consulting services, the consulting
agreement provides for a fee of $700,000 per annum.  Pursuant to the agreement,
a portion of such consulting fee will be deferred at an annual rate of
approximately $250,000 per annum.  The deferred amounts will be paid in monthly
installments over a 240-month period commencing on the later of the first
business day of the first full calendar month following December 31, 2002, and
the termination of Mr. Vierra's position as a consultant to TCI, together with
interest thereon at the rate of 8% per annum, compounded annually, from the date
of deferral to the payment date.  In the event of Mr. Vierra's death, all
outstanding deferred amounts will be paid in a lump sum to his beneficiaries.

     While Mr. Vierra is a consultant to TCI pursuant to the agreement, he is
entitled to participate in all insurance plans or policies adopted for the
benefit of TCI's employees.  The consulting agreement provides that all options
for TCI Common Stock and TINTA Common Stock held by Mr. Vierra are now vested in
full.  In addition, restricted stock awards for TINTA Common Stock shall vest
upon the expiration of the terms provided by the agreements evidencing their
respective grants.  See "THE MERGER--Interests of Certain Persons in the
Merger."

     Upon termination of the consulting agreement by TCI, TCI will pay all
remaining compensation due under the agreement for the balance of the term of
the agreement.  Upon Mr. Vierra's death during the term of the consulting

                                       47
<PAGE>
 
agreement, TCI will pay to Mr. Vierra's beneficiaries a lump sum in an amount
equal to one year's compensation.  The consulting agreement provides further
that, during the term of the agreement, Mr. Vierra will not be connected in any
manner with any entity which directly competes in a material respect with the
business of TCI or any of its majority-owned subsidiaries, which includes TINTA.
Mr. Vierra may, however, own securities of any corporation listed on a national
securities exchange or quoted on The Nasdaq Stock Market to the extent of an
aggregate of 5% of the amount of such securities outstanding.  In addition, Mr.
Vierra may provide consulting services to others if approved by TCI's chief
executive officer.

     Employment Agreement with Mr. Evans.  Mr. Evans commenced employment as
TINTA's President and Chief Operating Officer effective September 1, 1997, and
as TINTA's Chief Executive Officer in January 1998, pursuant to the terms of a
five-year employment agreement with TINTA.  The employment agreement provides
for a base salary of $600,000 per annum.  Such salary is subject to annual
review by the TINTA Board, which may, in its sole discretion, increase Mr.
Evans' salary.  In addition, Mr. Evans will receive an annual bonus of $200,000,
payable in two equal installments on February 1 and September 1 of each year,
commencing February 1, 1998.  The employment agreement allows for discretionary
bonuses as well.

     Pursuant to the terms of the employment agreement, TINTA issued to Mr.
Evans on each of September 1, 1997 and 1998, $500,000 of TINTA Series A Stock
(30,075 shares and 23,194 shares in 1997 and 1998, respectively) and is required
to issue to Mr. Evans on each of the next three successive anniversaries of such
latter issuance an additional $500,000 of TINTA Series A Stock.  On September 1,
1997, TINTA also granted Mr. Evans options to purchase 450,000 shares of TINTA
Series A Stock with an exercise price of $14.625 per share.  Such options have
been granted pursuant to the terms of the TINTA 1995 Plan and vest evenly over
the succeeding five years.  See "THE MERGER--Interests of Certain Persons in the
Merger--TINTA Options and Stock Appreciation Rights."  At such time as Mr. Evans
relocates to Denver, Colorado, TINTA will reimburse Mr. Evans for his reasonable
relocation expenses. The agreement allows Mr. Evans to be based in Los Angeles,
California until August 31, 1999, after which time he will be based at TINTA's
principal offices.  While he is employed by TINTA pursuant to his employment
agreement, Mr. Evans is entitled to participate in all formal incentive
compensation plans, stock incentive plans, employee stock purchase plans,
retirement plans and insurance plans or policies adopted for the benefit of
TINTA's or TCI's executive officers or employees generally.

     Mr. Evans' employment agreement provides further that during the term of
his employment with TINTA, Mr. Evans will not be connected with any entity in
any manner, which directly competes in a material respect with the business of
TINTA or any of its major-owned subsidiaries.  Mr. Evans may, however, own
securities of any corporation listed on a national securities exchange or quoted
on The Nasdaq Stock Market to the extent of an aggregate of 5% of the amount of
such securities outstanding.

     Mr. Evans' employment agreement terminates on August 31, 2002.  The
employment agreement provides that upon an earlier termination of Mr. Evans'
employment by TINTA without cause, all remaining compensation due under such
agreement for the balance of the employment term would become immediately due
and payable to Mr. Evans. Upon his death during the employment term, TINTA would
pay to Mr. Evans' beneficiaries all compensation accrued to the date of death.
In the event of his disability, TINTA would continue to pay Mr. Evans his annual
salary as and when it would have otherwise become due until the first to occur
of the end of the employment term or the date of his death.

     Following the consummation of the Merger, TINTA's employment agreement with
Mr. Evans shall continue on the same terms as were in effect immediately prior
to the Merger, except that all TINTA Options granted to Mr. Evans shall become
Assumed Options and the $500,000 of TINTA Series A Stock issuable to Mr. Evans
on September 1 of each of the next three years shall instead be issuable in
shares of LMG Series A Stock.

             THE AT&T MERGER AND THE LIBERTY/VENTURES COMBINATION

     The following description of the AT&T Merger and the Liberty/Ventures
Combination is qualified in its entirety by reference to the complete text of
the AT&T Agreement (excluding the exhibits and schedules thereto), which is
incorporated by reference herein.  See "INCORPORATION OF CERTAIN DOCUMENTS BY
REFERENCE." Consummation of the Merger is not subject to the consummation of
either the AT&T Merger or the Liberty/Ventures Combination.

GENERAL

     On June 23, 1998, TCI and AT&T entered into the AT&T Agreement, which,
subject to the terms and conditions thereof, provides for the acquisition of TCI
by AT&T.  Such acquisition will be effected through the AT&T Merger, in which
Italy Merger Corp., a wholly-owned subsidiary of AT&T, will be merged with and
into TCI, with TCI as the surviving corporation.  As a result of the AT&T
Merger, TCI will become a wholly-owned subsidiary of AT&T, and stockholders of
TCI will become stockholders of AT&T.  See "--Consideration to be Received by
Holders of TCI Common Stock in the AT&T Merger."

     Following the AT&T Merger, AT&T plans to combine its consumer long
distance, wireless and Internet services units with the TCI Group's cable,
telecommunications and high-speed Internet businesses to create a new wholly-
owned subsidiary of AT&T, AT&T Consumer Services Company ("AT&T Consumer Co.").
Concurrently with the creation of AT&T Consumer Co., AT&T plans to issue shares
of a newly authorized class of common stock of AT&T intended to reflect the
separate performance of the assets and businesses of AT&T Consumer Co. ("AT&T
Consumer Co. Stock") in an exchange offer to holders of AT&T Common Stock.
Alternatively, AT&T may distribute shares of AT&T Consumer Co. Stock to holders
of AT&T Common Stock as a stock dividend.  In the event of an exchange offer,
the holders of shares of AT&T Common Stock (including the former holders of
shares of TCI Group Stock) would have an option to exchange their shares of AT&T
Common Stock for shares of AT&T Consumer Co. Stock up to the limit to be set
forth in such exchange offer.  In the case of a distribution, the holders of
shares of AT&T Common Stock (including the former holders of shares of TCI Group
Stock) would receive as a distribution from AT&T a certain number of shares, or
fraction of a share, of AT&T Consumer Co. Stock for each share of AT&T Common
Stock they hold.  Holders of shares of AT&T Liberty/Ventures Stock will not be
offered the opportunity to participate in such exchange offer or distribution,
as the case may be.  Consummation thereof, which is subject to AT&T stockholder
approval, is expected to occur following, but is not conditional upon, the
consummation of the AT&T Merger.

     In a separate proposed transaction, TCI has announced its intention to
consummate the Liberty/Ventures Combination, whereby the shares of TCIVG Stock
will be reclassified as shares of LMG Stock and, in connection with such
reclassification, the businesses and assets of the Liberty Media Group and the
TCI Ventures Group will be combined.  Following the Liberty/Ventures
Combination, the LMG Stock will reflect the separate performance of the
businesses and assets attributed to the combined entity.  See "--
Liberty/Ventures Combination."  The Liberty/Ventures Combination is expected to
occur prior to, but is not conditional upon, the consummation of the AT&T
Merger.

CONSIDERATION TO BE RECEIVED BY HOLDERS OF TCI COMMON STOCK IN THE AT&T MERGER

     In connection with the AT&T Merger, (i) each share of LMG Series A Stock
outstanding immediately prior to the effective time of the AT&T Merger (the
"AT&T Effective Time") will be converted into the right to receive one share of
AT&T Liberty/Ventures Class A Stock and each share of LMG Series B Stock
outstanding immediately prior to the AT&T Effective Time will be converted into
the right to receive one share of AT&T Liberty/Ventures Class B Stock, (ii) each
share of TCI Group Series A Stock outstanding immediately prior to the AT&T
Effective Time will be converted into the right to receive .7757 of a share of
AT&T Common Stock and each share of TCI Group Series B Stock outstanding
immediately prior to the AT&T Effective Time will be converted into the right to
receive .8533 of a share of AT&T Common Stock, and (iii) if the Liberty/Ventures
Combination has not occurred prior to the AT&T Effective Time, each share of
TCIVG Series A Stock will be converted into the right to receive 0.52 of a share
of AT&T 

                                       49
<PAGE>
 
Liberty/Ventures Class A Stock and each share of TCIVG Series B Stock will be
converted into the right to receive 0.52 of a share of AT&T Liberty/Ventures
Class B Stock, subject to TCI's right to adjust the foregoing exchange ratios
for the TCIVG Common Stock as it deems appropriate to reflect the relative
values of the TCI Ventures Group and the Liberty Media Group. The AT&T
Liberty/Ventures Stock to be issued in the AT&T Merger will be a newly
authorized class of common stock of AT&T which will be intended to reflect the
separate performance of the businesses and assets attributed to the
Liberty/Ventures Group. See "--Assets and Business of Liberty/Ventures Group
Following the AT&T Merger."

     In general, the AT&T Agreement provides that the holders of shares of AT&T
Liberty/Ventures Class A Stock and holders of shares of AT&T Liberty/Ventures
Class B Stock will vote together as a single class with the holders of shares of
AT&T Common Stock on all matters presented to such stockholders.  Holders of
AT&T Liberty/Ventures Class A Stock will be entitled to /1//\\10\\ of a vote for
each share of such stock held, holders of AT&T Liberty/ Ventures Class B Stock
will be entitled to one vote for each share of such stock held and holders of
AT&T Common Stock will be entitled to one vote for each share of such stock
held.

     It is expected that the Merger will be consummated prior to the anticipated
closing date of the AT&T Merger. In such event and assuming the AT&T Merger is
consummated, shares of TINTA Common Stock that are converted into shares of LMG
Series A Stock in the Merger will ultimately be converted into the right to
receive shares of AT&T Liberty/Ventures Class A Stock upon consummation of the
AT&T Merger in accordance with the AT&T Agreement. Consummation of the Merger,
however, is not contingent on the consummation of the AT&T Merger or the other
transactions contemplated by the AT&T Agreement, and in the event such
transactions are abandoned, former TINTA stockholders would continue to own
shares of LMG Series A Stock.  Consummation of the AT&T Merger is subject to
certain conditions, including the separate approvals of the stockholders of TCI
and AT&T and, accordingly, there can be no assurance that the AT&T Merger will
be consummated.  See "--Conditions to the AT&T Merger."

LIBERTY/VENTURES COMBINATION

     TCI has announced its intention, subject to TCI stockholder approval, to
consummate the Liberty/Ventures Combination, whereby (i) each share of TCIVG
Series A Stock will be reclassified as 0.52 of a share of LMG Series A Stock and
each share of TCIVG Series B Stock will be reclassified as 0.52 of a share of
LMG Series B Stock, and (ii) the assets and businesses of the Liberty Media
Group and the TCI Ventures Group will be combined.  The Liberty/Ventures
Combination is expected to occur prior to, but is not conditional upon, the
consummation of the AT&T Merger.  In connection with the Liberty/Ventures
Combination, following receipt of the requisite TCI stockholder approval, the
TCI Charter will be amended to (i) reflect the reclassification of each series
of TCIVG Stock as the corresponding series of LMG Stock, (ii) delete all
references to the TCI Ventures Group currently contained in the TCI Charter, and
(iii) redefine the term "Liberty Media Group" in the TCI Charter to include the
assets and businesses held by the TCI Ventures Group immediately prior to the
combination of the Liberty Media Group and the TCI Ventures Group.

     In addition, upon the effectiveness of the amendments to the TCI Charter
which are required to effect the Liberty/Ventures Combination, TCI will cause
all of the capital stock of Liberty, the entity which holds all the assets and
businesses attributed to the Liberty Media Group, to be contributed to TCI
Ventures Group, L.L.C., the entity which holds all the assets and businesses
attributed to the TCI Ventures Group.   The name of TCI Ventures Group, L.L.C.
will then be changed to Liberty Media Group, L.L.C.

     Following the Liberty/Ventures Combination, the combined Liberty Media
Group and TCI Ventures Group will be called the "Liberty Media Group" (herein
referred to as Liberty/Ventures Group), and the LMG Stock will reflect the
separate performance of the businesses and assets attributed to the
Liberty/Ventures Group.  John C. Malone, Chairman and Chief Executive Officer of
TCI, will be Chairman of the Liberty/Ventures Group, Robert R. Bennett,
President and Chief Executive Officer of Liberty, will be President and Chief
Executive Officer of the Liberty/Ventures Group and Gary S. Howard, currently
President and Chief Executive Officer of TCI Ventures Group, L.L.C. and

                                       50
<PAGE>
 
Executive Vice President and Chief Operating Officer of Liberty, will be Senior
Vice President and Chief Operating Officer of the Liberty/Ventures Group.

     Consummation of the Liberty/Ventures Combination is subject to certain
conditions, including approval of the TCI stockholders.  Moreover, TCI has no
contractual obligation to effect the Liberty/Ventures Combination. Accordingly,
there can be no assurance that the Liberty/Ventures Combination will be
consummated.

ASSETS AND BUSINESS OF THE LIBERTY/VENTURES GROUP FOLLOWING THE AT&T MERGER

     Following the AT&T Merger, the Liberty/Ventures Group will comprise the
corporations, partnerships and other entities and interests which, at the time
of the AT&T Merger, comprise the Liberty/Ventures Group or, if the
Liberty/Ventures Combination has not occurred, the Liberty Media Group and the
TCI Ventures Group.  Pursuant to the AT&T Agreement, prior to, and conditional
upon, the closing of the AT&T Merger, certain assets currently attributed to the
TCI Ventures Group (including, among others, the shares of AT&T Common Stock
received in the merger of AT&T and Teleport Communications Group, Inc., the
stock of At Home Corporation and the assets of, or outstanding equity interests
in, the National Digital Television Center, Inc.) will be transferred to the TCI
Group in exchange for approximately $5.5 billion in cash.  Certain other
transfers of assets among the Groups will also occur, including the transfer to
the Liberty/Ventures Group of certain warrants currently attributed to the TCI
Group in exchange for up to $176 million in cash.  In addition, upon
consummation of the AT&T Merger, the Liberty/Ventures Group will become entitled
to the benefit of all the net operating loss carryforwards available to the
entities included in TCI's consolidated income tax return as of the date of the
AT&T Merger.

     After giving effect to such transfers, the Liberty/Ventures Group will be
engaged in three principal lines of business: (i) production, acquisition and
distribution through all available formats and media of branded entertainment,
educational and informational programming and software, including multimedia
products; (ii) electronic retailing, direct marketing, advertising sales
relating to programming services, infomercials and transaction processing; and
(iii) international cable distribution, satellite distributed programming
services and various investments in distribution technology.

OPERATIONS AND MANAGEMENT OF THE LIBERTY/VENTURES GROUP FOLLOWING THE AT&T
MERGER

     Following the AT&T Merger, AT&T will own 100% of the businesses and assets
that comprise the Liberty/Ventures Group.  However, the day-to-day management of
the businesses of the Liberty/Ventures Group will remain independent of AT&T
management.  The AT&T Agreement provides that the Liberty/Ventures Group will
continue to be managed by certain members of TCI's management who currently
manage the businesses of the Liberty Media Group and the TCI Ventures Group and
who, if the Liberty/Ventures Combination shall have been consummated, will have
been managing the business of the Liberty/Ventures Group.  See "--
Liberty/Ventures Combination."

     In addition, the AT&T Agreement contemplates the execution of certain
agreements at the AT&T Effective Time which will, among other things, (i)
provide preferred vendor status to Liberty for digital basic distribution on
AT&T's systems of new programming services created by Liberty and its
affiliates, (ii) provide for a renewal of existing affiliation agreements of
Liberty and its affiliates, and (iii) provide interactive video services to
Liberty pursuant to a five-year arrangement, renewable for an additional four-
year period on then-current "most favored nation" terms.

CONDITIONS TO THE AT&T MERGER

     Consummation of the AT&T Merger is subject to the satisfaction or, where

TCI (including the former holders of TINTA Common Stock if the Merger shall have
been consummated), (b) effective registration under the Securities Act of the
shares of AT&T Common Stock and AT&T Liberty/Ventures Stock to be issued to TCI

                                       51
<PAGE>
 
applicable under the HSR Act, (d) absence of any effective injunction or similar
order preventing consummation of the transactions contemplated by the AT&T
Agreement, (e) receipt by TCI and AT&T of certain opinions from their respective
legal counsel to the effect that, among other things, the AT&T Merger should
qualify as a tax-free reorganization for federal income tax purposes, and (f)
receipt of authorization for listing of the shares of AT&T Common Stock and AT&T
Liberty/Ventures Stock on The New York Stock Exchange, Inc. ("NYSE") or, in the
case of AT&T Liberty/Ventures Stock, the NASDAQ/NM, subject only to official
notice of issuance.

TERMINATION OF THE AT&T AGREEMENT

     The AT&T Agreement may be terminated and the AT&T Merger abandoned at any
time prior to the AT&T Effective Time, by (a) the mutual consent of TCI and
AT&T; (b) either TCI or AT&T (i) if the AT&T Merger has not been consummated by
March 31, 1999; provided, however, that the party seeking to terminate did not
fail to fulfill any obligation causing the AT&T Merger not to be consummated by
that date, and provided, further that such date may be extended (1) first to
June 30, 1999 by either party in the event that the delay is attributable to a
transaction permitted in connection with obtaining regulatory approval, due to
the failure to have obtained the requisite regulatory approvals or due to an
injunction or other governmental action preventing the consummation of the AT&T
Merger, and (2) then to September 30, 1999 as long as the party extending such
date believes in good faith that such conditions are capable of being satisfied
on such date, (ii) if a court of competent jurisdiction or governmental entity
has issued a final and nonappealable order enjoining or prohibiting the AT&T
Merger, or (iii) if the requisite approvals of the stockholders of TCI and AT&T
of the transactions contemplated by the AT&T Agreement have not been duly
obtained on or prior to March 31, 1999; (c) by AT&T or Italy Merger Corp. (i) if
the TCI Board has withdrawn or modified its approval or recommendation of the
transactions contemplated by the AT&T Agreement, or (ii) if TCI breaches or
fails in any material respect to perform or comply with its covenants and
agreements or breaches its representations and warranties contained in the AT&T
Agreement, in each case in a manner that is not curable, (d) by AT&T if certain
stockholders of TCI who entered into a voting agreement with respect to the AT&T
Merger have breached any of their respective representations, covenants or
obligations thereunder in any material respect and such breach is not curable;
or (e) by TCI (i) if the Board of Directors of AT&T (the "AT&T Board") has
withdrawn or modified its approval or recommendation of the transactions
contemplated by the AT&T Agreement, or (ii) if AT&T or Italy Merger Corp.
breaches or fails in any material respect to perform or comply with its
covenants and agreements or breaches its representations and warranties
contained in the AT&T Agreement, in each case in a manner that is not curable.

     AT&T will be required to pay TCI a termination fee equal to $1.75 billion
in cash if TCI terminates the AT&T Agreement due to (i) the failure of AT&T's
stockholders to approve the transactions contemplated by the AT&T Agreement by
the requisite vote prior to March 31, 1999, (ii) the withdrawal or modification
by the AT&T Board of its approval or recommendation of such transactions, or
(iii) the failure to obtain necessary governmental and regulatory approvals by
September 30, 1999, which failure occurs as a result of the announcement by AT&T
of a significant transaction that delays receipt of such governmental approvals.
TCI will be required to pay AT&T a termination fee equal to $1.75 billion in
cash if AT&T terminates the AT&T Agreement due to the failure of TCI
stockholders to approve the transactions contemplated by the AT&T Agreement by
the requisite vote prior to March 31, 1999 or the withdrawal or modification by
the TCI Board of its approval or recommendation of such transactions.

REGISTRATION AND LISTING OF AT&T STOCK

     The AT&T Agreement provides that the shares of AT&T Common Stock and AT&T
Liberty/Ventures Stock issued pursuant to the AT&T Agreement will be registered
under the applicable provisions of the Securities Act and, if required, under
any applicable state securities laws.  Such shares also will be listed for
trading on the NYSE or, in the case of the AT&T Liberty/Ventures Stock, at
AT&T's option, on the NASDAQ/NM.

in shares of LMG Stock, with respect to which adjustment will be made as
described in clause (i) of the definition of "Number of Shares Issuable with
Respect to the Liberty Media Group Inter-Group Interest," or in other securities
of TCI attributed to the Liberty Media Group for which provision will be made as
described in the penultimate sentence of this definition), the Liberty Media

denominator of which is equal to the Liberty Media Group Outstanding Interest
Fraction in effect immediately prior to the record date for such dividend or
other distribution and (b) from and after any transfer of assets or properties

longer include the assets or properties so transferred. If TCI pays a dividend
or makes any other distribution with respect to shares of LMG Stock payable in
securities of TCI attributed to the Liberty Media Group other than LMG Stock,
the TCI Group will be deemed to hold an amount of such other securities equal to
the amount so distributed multiplied by the fraction specified in clause (a) of
this definition (determined as of a time immediately prior to the record date
for such dividend or other distribution), and to the extent interest or
dividends are paid or other distributions are made on such other securities so
distributed to the holders of LMG Stock, the Liberty Media Group will no longer
include a corresponding ratable amount of the kind of assets paid as such
interest or dividends or other distributions in respect of such securities so
deemed to be held by the TCI  Group.  TCI may also, to the extent any such other
securities constitute Convertible Securities which are at the time convertible,
exercisable or exchangeable, cause such Convertible Securities deemed to be held
by the TCI Group to be deemed to be converted, exercised or exchanged (and to
the extent the terms of such Convertible Securities require payment or delivery
of consideration in order to effect such conversion, exercise or exchange, the
Liberty Media Group will in such case include an amount of the kind of
properties or assets required to be paid or delivered as such consideration for
the amount of the Convertible Securities deemed converted, exercised or
exchanged as if such Convertible Securities were outstanding), in which case
such Convertible Securities will no longer be deemed to be held by the TCI Group
or attributed to the Liberty Media Group.

     "Liberty Media Group Inter-Group Interest Fraction," as of  any date, shall
mean a fraction the numerator of which is the Number of Shares Issuable with
Respect to the Liberty Media Group Inter-Group Interest as of such date and the
denominator of which is the sum of (a) such Number of Shares Issuable with

to any Disposition of any of the properties and assets of the Liberty Media
Group, an amount, if any, equal to the gross proceeds of such Disposition after
any payment of, or reasonable provision for, (a) any taxes payable by TCI in
respect of such Disposition or in respect of any resulting dividend or
redemption pursuant to clause (i) or (ii), respectively, of the second paragraph
under "--Conversion and Redemption--Mandatory Dividend, Redemption or Conversion
of LMG Stock" (or which would have been payable but for the utilization of tax
benefits attributable to the TCI Group or the TCI Ventures Group), (b) any
transaction costs, including, without limitation, any legal, investment banking
and accounting fees and expenses and (c) any liabilities and other obligations
(contingent or otherwise) of, or attributed to, the Liberty Media Group,

in connection with the Disposition or any liabilities for future purchase price
adjustments and any preferential amounts plus any accumulated and unpaid
dividends and other obligations (without duplication of amounts allocated for
the satisfaction of TCI's obligations with respect to Pre-Distribution
Convertible Securities and Committed Acquisition Shares issuable which are
included in the determination of the Adjusted Liberty Media Group Outstanding
Interest Fraction) in respect of TCI Preferred Stock attributed to the Liberty
Media Group.  For purposes of this definition, any properties and assets of the
Liberty Media Group remaining after such Disposition shall constitute
"reasonable provision" for such amount of taxes, costs and liabilities
(contingent or otherwise) as can be supported by such properties and assets.  To
the extent the proceeds of any 

                                       56
<PAGE>
 
Disposition include any securities or other property other than cash, the TCI
Board shall determine the value of such securities or property, including for
the purpose of determining the equivalent value thereof if the TCI Board

the Number of Shares Issuable with Respect to the Liberty Media Group Inter-
Group Interest as of such date.

     "Lower Appraised Amount," with respect to any determination of the Liberty
Media Group Private Market Value or the TCI Ventures Group Private Market Value,
shall mean the lower of the respective final views of the First Appraiser and

powers, preferences or special rights of one or more series of the class so as
to affect them adversely, but would not so affect the entire class, then only
the shares of the series so affected by the amendment would be entitled to vote
thereon separately as a class.  Because the TCI Group Series A Stock, the TCI
Group Series B Stock, the LMG Series A Stock, the LMG Series B Stock, the TCIVG
Series A Stock and the TCIVG Series B Stock are each a separate series of a
single class of stock, each series will be entitled to vote separately as a
class upon an amendment to the Charter that would alter or change the powers,
preferences or special rights of such series so as to affect them adversely only
if the other series were not so affected. The DGCL does not provide for any
other separate voting rights of a class or series of capital stock (other than
with respect to a change in par value or, in certain circumstances not
applicable in the case of TCI's outstanding stock, an increase or decrease in
the authorized shares of such class or series).  Consequently, because most
matters brought to a stockholder vote will require the approval of only a
specified percentage of all of TCI's outstanding capital stock entitled to vote
on such matters (including the TCI Group Stock, the LMG Stock and the TCIVG
Stock) voting together as a single class, if the holders of one or more series
of TCI Common Stock have more than the number of votes required to approve any
such matter, such holders would be in a position to control the outcome of the
vote on such matter.

     DIVIDENDS

     Subject to the prior payment of dividends on, and other rights of, any of
the outstanding shares of TCI Preferred Stock, dividends may be paid as
determined by the TCI Board (i) on the TCI Group Stock out of the lesser of (x)
the TCI Group Available Dividend Amount and (y) funds of TCI legally available
therefor under the DGCL, (ii) on the LMG Stock out of the lesser of (x) the
Liberty Media Group Available Dividend Amount and (y) funds of TCI legally
available therefor under the DGCL, and (iii) on the TCIVG Stock out of the
lesser of (x) the TCI Ventures Group Available Dividend Amount and (y) funds of
TCI legally available therefor under the DGCL.  Under the DGCL, the amount of
the funds of TCI legally available for the payment of dividends on any series of
TCI Common Stock is determined on the basis of the entire corporation and not
just the TCI Group, the Liberty Media Group or the TCI Ventures Group.
Consequently, the amount of legally available funds will be reduced by the
amount of any net losses of the TCI Group, the Liberty Media Group or the TCI
Ventures Group and any dividends or distributions on, or repurchases of, the TCI
Group Stock, the LMG Stock or the TCIVG Stock, if any, and dividends on, or
certain repurchases of, TCI Preferred Stock.  Certain loan agreements to which
certain subsidiaries of TCI are parties or are subject contain restricted
payment provisions that limit the amount of dividends, other than stock
dividends, that those companies may pay.  Future loan agreements may also
contain similar restrictions and limits.

     The "TCI Group Available Dividend Amount," as of any date, means either (i)
the excess of (a) an amount equal to the total assets of the TCI Group less the
total liabilities (not including preferred stock) of the TCI Group as of such
date over (b) the aggregate par value of, or any greater amount determined to be
capital in respect of, all outstanding shares of TCI Group Stock and each class
or series of TCI Preferred Stock attributed to the TCI Group or (ii) in case
there is no such excess, an amount equal to the Corporation Earnings (Loss)
Attributable to the TCI Group (if positive) for the fiscal year in which such
date occurs and/or the preceding fiscal year.  The "Corporation Earnings (Loss)
Attributable to the TCI Group," for any period, means the net earnings or loss
of the TCI Group for such period, determined on a basis consistent with the
determination of the net earnings or loss of the TCI Group for such period as
presented in the combined financial statements of the TCI Group, including
income and expenses of TCI attributed to the operations of the TCI Group on a
substantially consistent basis, including, without limitation, corporate
administrative costs, net interest and income taxes.  The TCI Group Available
Dividend Amount is intended to be similar to the amount that would be legally
available for the payment of dividends on the TCI Group Stock under the DGCL if
the TCI Group were a separate Delaware corporation.  There can be no assurance
that there will be a TCI Group Available Dividend Amount.

     The "Liberty Media Group Available Dividend Amount," as of any date, means
the product of the Liberty Media Group Outstanding Interest Fraction and either
(i) the excess of (a) an amount equal to the total assets of the Liberty Media
Group less the total liabilities (not including preferred stock) of the Liberty
Media Group as of such date over (b) the aggregate par value of, or any greater
amount determined to be capital in respect of, all outstanding shares of LMG
Stock and each class or series of TCI Preferred Stock attributed to the Liberty
Media Group or (ii) in case there is no such excess, an amount equal to the
Corporation Earnings (Loss) Attributable to the Liberty Media Group (if
positive) for the fiscal year in which such date occurs and/or the preceding
fiscal year.  The "Corporation Earnings (Loss) Attributable to the Liberty Media
Group," for any period, means the net earnings or loss of the Liberty Media
Group for such period determined on a basis consistent with the determination of
the net earnings or loss of the Liberty Media Group for such period as presented
in the combined financial statements of the Liberty Media Group, including
income and expenses of TCI attributed to the operations of the Liberty Media
Group on a substantially consistent basis, including, without limitation,
corporate administrative costs, net interest and income taxes.  The Liberty
Media Group Available Dividend Amount is intended to be similar to the amount
that would be legally available for the payment of dividends on the LMG Stock
under the DGCL if the Liberty Media Group were a separate Delaware corporation.
There can be no assurance that there will be a Liberty Media Group Available
Dividend Amount.

     The "TCI Ventures Group Available Dividend Amount," as of any date, means
the product of the TCI Ventures Group Outstanding Interest Fraction and either
(i) the excess of (a) an amount equal to the total assets of the TCI Ventures
Group less the total liabilities (not including preferred stock) of the TCI
Ventures Group as of such date over (b) the aggregate par value of, or any
greater amount determined to be capital in respect of, all outstanding shares of

                                       64
<PAGE>
 
TCIVG Stock and each class or series of TCI Preferred Stock attributed to the
TCI Ventures Group or (ii) in case there is no such excess, an amount equal to
the Corporation Earnings (Loss) Attributable to the TCI Ventures Group (if
positive) for the  fiscal year in which such date occurs and/or the preceding
fiscal year.  The "Corporation Earnings (Loss) Attributable to the TCI Ventures
Group," for any period, means the net earnings or loss of the TCI Ventures Group
for such period determined on a basis consistent with the determination of the
net earnings or loss of the TCI Ventures Group for such period as presented in
the combined financial statements of the TCI Ventures Group, including income
and expenses of TCI attributed to the operations of the TCI Ventures Group on a
substantially consistent basis, including, without limitation, corporate
administrative costs, net interest and income taxes.  The TCI Ventures Group
Available Dividend Amount is intended to be similar to the amount that would be
legally available for the payment of dividends on the TCIVG Stock under the DGCL
if the TCI Ventures Group were a separate Delaware corporation. There can be no
assurance that there will be a TCI Ventures Group Available Dividend Amount.

     Except for dividends declared or paid as described below under "--Share
Distributions," "--Conversion and Redemption--Mandatory Dividend, Redemption or
Conversion of LMG Stock," and "--Conversion and Redemption--Mandatory Dividend,
Redemption or Conversion of TCIVG Stock," any dividends paid on the TCI Group
Series A Stock or the TCI Group Series B Stock will be paid only on both series,
in equal amounts per share; any dividends paid on the LMG Series A Stock or the
LMG Series B Stock will be paid only on both series, in equal amounts per share;
and any dividends paid on the TCIVG Series A Stock or the TCIVG Series B Stock
will be paid only on both series, in equal amounts per share.

     The TCI Board, subject to the provisions described above and under "--Share
Distributions" below, has the authority and discretion to declare and pay
dividends on the TCI Group Stock, the LMG Stock or the TCIVG Stock in equal or
unequal amounts, notwithstanding the relationship among the TCI Group Available
Dividend Amount, the Liberty Media Group Available Dividend Amount and the TCI
Ventures Group Available Dividend Amount, the respective amounts of prior
dividends declared on, or liquidation rights of, the TCI Group Stock, the LMG
Stock or the TCIVG Stock or any other factor.

     At the time of any dividend or other distribution on the outstanding shares
of LMG Stock (including any dividend of Liberty Media Group Net Proceeds from
the Disposition of all or substantially all of the properties and assets of the
Liberty Media Group as described below under "--Conversion and Redemption--
Mandatory Dividend, Redemption or Conversion of LMG Stock"), the TCI Group will
(if at such time there is an Inter-Group Interest in the Liberty Media Group) be
credited, and the Liberty Media Group will be charged (in addition to the charge
for the dividend or other distribution paid or distributed in respect of
outstanding shares of LMG Stock), with an amount equal to the product of (i) the
aggregate amount of such dividend or distribution paid or distributed in respect
of outstanding shares of LMG Stock times (ii) a fraction the numerator of which
is the Liberty Media Group Inter-Group Interest Fraction and the denominator of
which is the Liberty Media Group Outstanding Interest Fraction.

     At the time of any dividend or other distribution on the outstanding shares
of TCIVG Stock (including any dividend of TCI Ventures Group Net Proceeds from
the Disposition of all or substantially all of the properties and assets of the
TCI Ventures Group as described under "--Conversion and Redemption--Mandatory
Dividend, Redemption or Conversion of TCIVG Stock"), the TCI Group will (if at
such time there is an Inter-Group Interest in the TCI Ventures Group) be
credited, and the TCI Ventures Group will be charged (in addition to the charge
for the dividend or other distribution paid or distributed in respect of
outstanding shares of TCIVG Stock), with an amount equal to the product of (i)
the aggregate amount of such dividend or distribution paid or distributed in
respect of outstanding shares of TCIVG Stock times (ii) a fraction the numerator
of which is the TCI Ventures Group Inter-Group Interest Fraction and the
denominator of which is the TCI Ventures Group Outstanding Interest Fraction.

     SHARE DISTRIBUTIONS

     Distributions on TCI Group Stock.  If at any time after the initial
issuance of shares of TCIVG Stock, a distribution paid in TCI Group Stock, LMG
Stock, TCIVG Stock, or any other securities of TCI or any other person 

                                       65
<PAGE>
 
(a "share distribution"), is made with respect to the TCI Group Stock, such
share distribution will be declared and paid only as follows:

          (i)   a share distribution consisting of shares of TCI Group Series A
     Stock (or Convertible Securities convertible into or exercisable or

     Group Series A Stock and TCI Group Series B Stock, on an equal per share
     basis; or consisting of shares of TCI Group Series B Stock (or Convertible
     Securities convertible into or exercisable or exchangeable for shares of
     TCI Group Series B Stock) to holders of TCI Group Series A Stock and TCI
     Group Series B Stock, on an equal per share basis; or consisting of shares
     of TCI Group Series A Stock (or Convertible Securities convertible into or
     exercisable or exchangeable for shares of TCI Group Series A Stock) to
     holders of TCI Group Series A Stock and, on an equal per share basis,
     shares of TCI Group Series B Stock (or like Convertible Securities
     convertible into or exercisable or exchangeable for shares of TCI Group
     Series B Stock) to holders of TCI Group Series B Stock;

          (ii)  a share distribution consisting of shares of LMG Series A Stock
     (or Convertible Securities convertible into or exercisable or exchangeable
     for shares of LMG Series A Stock) to holders of TCI Group Series A Stock
     and TCI Group Series B Stock, on an equal per share basis; provided that
     the sum of (A) the aggregate number of shares of LMG Series A Stock to be
     so issued (or the number of such shares which would be issuable upon
     conversion, exercise or exchange of any Convertible Securities to be so
     issued) and (B) the number of shares of such series that are subject to
     issuance upon conversion, exercise or exchange of any Convertible
     Securities then outstanding that are attributed to the TCI Group (other
     than Pre-Distribution Convertible Securities and other than Convertible
     Securities convertible into or exercisable or exchangeable for Committed
     Acquisition Shares) is less than or equal to the Number of Shares Issuable
     with Respect to the Liberty Media Group Inter-Group Interest;

          (iii) a share distribution consisting of shares of TCIVG Series A
     Stock (or Convertible Securities convertible into or exercisable or

     Series A Stock and TCI Group Series B Stock, on an equal per share basis;
     or consisting of shares of TCIVG Series B Stock (or Convertible Securities
     convertible into or exercisable or exchangeable for shares of TCIVG Series
     B Stock) to holders of TCI Group Series A Stock and TCI Group Series B
     Stock, on an equal per share basis; or consisting of shares of TCIVG Series
     A Stock (or Convertible Securities convertible into or exercisable or
     exchangeable for shares of TCIVG Series A Stock) to holders of TCI Group
     Series A Stock and, on an equal per share basis, shares of TCIVG Series B
     Stock (or like Convertible Securities convertible into or exercisable or
     exchangeable for shares of TCIVG Series B Stock) to holders of TCI Group
     Series B Stock; provided that the sum of (A) the aggregate number of shares
     of TCIVG Series A Stock and TCIVG Series B Stock to be so distributed (or
     the number of such shares which would be issuable upon conversion, exercise
     or exchange of any Convertible Securities to be so distributed) and (B) the
     number of shares of TCIVG Series A Stock and TCIVG Series B Stock that are
     subject to issuance upon conversion, exercise or exchange of any
     Convertible Securities then outstanding that are attributed to the TCI
     Group (other than Pre-Exchange Offer Securities) is less than or equal to
     the Number of Shares Issuable with Respect to the TCI Ventures Group Inter-
     Group Interest; and

          (iv)  a share distribution consisting of any class or series of
     securities of TCI or any other person other than TCI Group Stock, LMG Stock
     or TCIVG Stock (or Convertible Securities convertible into or exercisable
     or exchangeable for shares of TCI Group Stock, LMG Stock or TCIVG Stock),
     either on the basis of a distribution of identical securities, on an equal
     per share basis, to holders of TCI Group Series A Stock and TCI Group
     Series B Stock or on the basis of a distribution of one class or series of
     securities to holders of TCI Group Series A Stock and another class or
     series of securities to holders of TCI Group Series B Stock, provided that
     the securities so distributed (and, if the distribution consists of
     Convertible Securities, the securities into which such Convertible
     Securities are convertible or for which they are exercisable or
     exchangeable) do not differ in any respect other than their relative voting
     rights and related differences in designation, conversion, redemption and
     share distribution provisions, with holders of shares of TCI Group Series B
     Stock receiving 

                                       66
<PAGE>
 
     the class or series having the higher relative voting rights (without
     regard to whether such rights differ to a greater or lesser extent than the
     corresponding differences in voting rights, designation, conversion,
     redemption and share distribution provisions between the TCI Group Series A
     Stock and the TCI Group Series B Stock), provided that if the securities so
     distributed constitute capital stock of a Subsidiary of TCI, such rights
     will not differ to a greater extent than the corresponding differences in
     voting rights, designation, conversion, redemption and share distribution
     provisions between the TCI Group Series A Stock and the TCI Group Series B
     Stock, and provided in each case that such distribution is otherwise made
     on an equal per share basis.

     TCI will not reclassify, subdivide or combine the TCI Group Series A Stock
without reclassifying, subdividing or combining the TCI Group Series B Stock, on
an equal per share basis, and TCI will not reclassify, subdivide or combine the
TCI Group Series B Stock without reclassifying, subdividing or combining the TCI
Group Series A Stock, on an equal per share basis.

     Distributions on LMG Stock.  If at any time a share distribution is to be
made with respect to the LMG Stock, such share distribution will be declared and
paid only as follows (or as described under "--Conversion and Redemption" with
respect to the redemptions and other distributions referred to therein):

          (i)   a share distribution consisting of shares of LMG Series A Stock
     (or Convertible Securities convertible into or exercisable or exchangeable
     for shares of LMG Series A Stock) to holders of LMG Series A Stock and LMG
     Series B Stock, on an equal per share basis; or consisting of shares of LMG
     Series B Stock (or Convertible Securities convertible into or exercisable
     or exchangeable for shares of LMG Series B Stock) to holders of LMG Series
     A Stock and LMG Series B Stock, on an equal per share basis; or consisting
     of shares of LMG Series A Stock (or Convertible Securities convertible into
     or exercisable or exchangeable for shares of LMG Series A Stock) to holders
     of LMG Series A Stock and, on an equal per share basis, shares of LMG
     Series B Stock (or like Convertible Securities convertible into or
     exercisable or exchangeable for shares of LMG Series B Stock) to holders of
     LMG Series B Stock; and

          (ii)  a share distribution consisting of any class or series of
     securities of TCI or any other person other than as described in the
     immediately preceding clause (i) and other than TCI Group Stock or TCIVG
     Stock (or Convertible Securities convertible into or exercisable or
     exchangeable for shares of TCI Group Stock or TCIVG Stock), either on the
     basis of a distribution of identical securities, on an equal per share
     basis, to holders of LMG Series A Stock and LMG Series B Stock or on the
     basis of a distribution of one class or series of securities to holders of
     LMG Series A Stock and another class or series of securities to holders of
     LMG Series B Stock, provided that the securities so distributed (and, if
     the distribution consists of Convertible Securities, the securities into
     which such Convertible Securities are convertible or for which they are
     exercisable or exchangeable) do not differ in any respect other than their
     relative voting rights and related differences in designation, conversion,
     redemption and share distribution provisions, with holders of shares of LMG
     Series B Stock receiving the class or series having the higher relative
     voting rights (without regard to whether such rights differ to a greater or
     lesser extent than the corresponding differences in voting rights,
     designation, conversion, redemption and share distribution provisions
     between the LMG Series A Stock and the LMG Series B Stock), provided that
     if the securities so distributed constitute capital stock of a Subsidiary
     of TCI, such rights will not differ to a greater extent than the
     corresponding differences in voting rights, designation, conversion,
     redemption and share distribution provisions between the LMG Series A Stock
     and the LMG Series B Stock, and provided in each case that such
     distribution is otherwise made on an equal per share basis.

     Because under the TCI Charter the Liberty Media Group is not permitted to
have an Inter-Group Interest in either the TCI Group or the TCI Ventures Group,
no distributions on the LMG Stock of shares of TCI Group Stock (or related
Convertible Securities) or TCIVG Stock (or related Convertible Securities) are
permitted.

     TCI will not reclassify, subdivide or combine the LMG Series A Stock
without reclassifying, subdividing or combining the LMG Series B Stock, on an
equal per share basis, and TCI will not reclassify, subdivide or combine the 

                                       67
<PAGE>
 
LMG Series B Stock without reclassifying, subdividing or combining the LMG
Series A Stock, on an equal per share basis.

     Distributions on TCIVG Stock.  If at any time a share distribution is to be
made with respect to the TCIVG Stock, such share distribution will be declared
and paid only as follows (or as described under "--Conversion and Redemption"
with respect to the redemptions and other distributions referred to therein):

          (i)   a share distribution consisting of shares of TCIVG Series A
     Stock (or Convertible Securities convertible into or exercisable or
     exchangeable for shares of TCIVG Series A Stock) to holders of TCIVG Series
     A Stock and TCIVG Series B Stock, on an equal per share basis; or
     consisting of shares of TCIVG Series B Stock (or Convertible Securities
     convertible into or exercisable or exchangeable for shares of TCIVG Series
     B Stock) to holders of TCIVG Series A Stock and TCIVG Series B Stock, on an
     equal per share basis; or consisting of shares of TCIVG Series A Stock (or
     Convertible Securities convertible into or exercisable or exchangeable for
     shares of TCIVG Series A Stock) to holders of TCIVG Series A Stock and, on
     an equal per share basis, shares of TCIVG Series B Stock (or like
     Convertible Securities convertible into or exercisable or exchangeable for
     shares of TCIVG Series B Stock) to holders of TCIVG Series B Stock; and

          (ii)  a share distribution consisting of any class or series of
     securities of TCI or any other person other than as described in the
     immediately preceding clause (i) and other than TCI Group Stock or LMG
     Stock (or Convertible Securities convertible into or exercisable or
     exchangeable for shares of TCI Group Stock or LMG Stock), either on the
     basis of a distribution of identical securities, on an equal per share
     basis, to holders of TCIVG Series A Stock and TCIVG Series B Stock or on
     the basis of a distribution of one class or series of securities to holders
     of TCIVG Series A Stock and another class or series of securities to
     holders of TCIVG Series B Stock, provided that the securities so
     distributed (and, if the distribution consists of Convertible Securities,
     the securities into which such Convertible Securities are convertible or
     for which they are exercisable or exchangeable) do not differ in any
     respect other than their relative voting rights and related differences in
     designation, conversion, redemption and share distribution provisions, with
     holders of shares of TCIVG Series B Stock receiving the class or series
     having the higher relative voting rights (without regard to whether such
     rights differ to a greater or lesser extent than the corresponding
     differences in voting rights, designation, conversion, redemption and share
     distribution provisions between the TCIVG Series A Stock and the TCIVG
     Series B Stock), provided that if the securities so distributed constitute
     capital stock of a Subsidiary of TCI, such rights will not differ to a
     greater extent than the corresponding differences in voting rights,
     designation, conversion, redemption and share distribution provisions
     between the TCIVG Series A Stock and the TCIVG Series B Stock, and provided
     in each case that such distribution is otherwise made on an equal per share
     basis.

     Because under the TCI Charter the TCI Ventures Group is not permitted to
have an Inter-Group Interest in either the TCI Group or the Liberty Media Group,
no distributions on the TCIVG Stock of shares of TCI Group Stock (or related
Convertible Securities) or LMG Stock (or related Convertible Securities) are
permitted.

     TCI will not reclassify, subdivide or combine the TCIVG Series A Stock
without reclassifying, subdividing or combining the TCIVG Series B Stock, on an
equal per share basis, and TCI will not reclassify, subdivide or combine the
TCIVG Series B Stock without reclassifying, subdividing or combining the TCIVG
Series A Stock, on an equal per share basis.

     CONVERSION AND REDEMPTION

     Conversion at the Option of the Holder.  Each share of TCI Group Series B
Stock is convertible, at the option of the holder thereof, into one share of TCI
Group Series A Stock.  Each share of LMG Series B Stock is convertible, at the
option of the holder thereof, into one share of LMG Series A Stock.  Each share
of TCIVG Series B Stock is convertible, at the option of the holder thereof,
into one share of TCIVG Series A Stock.  Shares of TCI Group Series A Stock are
not convertible into shares of TCI Group Series B Stock; shares of LMG Series A
Stock are not convertible

                                       68
<PAGE>
 
into shares of LMG Series B Stock; and shares of TCIVG Series A Stock are not
convertible into shares of TCIVG Series B Stock.

     Conversion of LMG Stock at the Option of  TCI.  The TCI Board may at any
time declare that (i) all of the outstanding shares of LMG Series A Stock will
be converted into a number (or fraction) of fully paid and nonassessable shares
of TCI Group Series A Stock equal to the Liberty Media Group Optional Conversion
Ratio, and (ii) all of the outstanding shares of LMG Series B Stock will be
converted into a number (or fraction) of fully paid and nonassessable shares of
TCI Group Series B Stock equal to the Liberty Media Group Optional Conversion
Ratio.  As more fully described below, the Liberty Media Group Optional
Conversion Ratio is the ratio of the private market value of a share of LMG
Stock determined by appraisal to the public trading price of a share of TCI
Group Stock.

     Under the TCI Charter, the "Liberty Media Group Optional Conversion Ratio"
means the quotient (calculated to the nearest five decimal places) obtained by
dividing (x) the LMG Stock Per Share Value by (y) the average Market Value of
one share of TCI Group Series A Stock over the 20-Trading Day period ending on
the Trading Day preceding the Appraisal Date.  The LMG Stock Per Share Value
will equal the quotient obtained by dividing the Liberty Media Group Private
Market Value by the Adjusted Outstanding Shares of LMG Stock, which will be
determined in the manner described below.

     The "Liberty Media Group Private Market Value" means an amount equal to the
private market value of the Liberty Media Group as of the Appraisal Date.  In
the event that TCI determines to establish the Liberty Media Group Private
Market Value, TCI shall designate the First Appraiser and the Independent
Committee shall designate the Second Appraiser.  Not later than 20 days after
the Selection Date, the First Appraiser and the Second Appraiser will each
determine its initial view as to the private market value of the Liberty Media
Group as of the Appraisal Date and will consult with one another with respect
thereto.  Not later than the 30th day after the Selection Date, the First
Appraiser and the Second Appraiser will each have determined its final view as
to such private market value.  If the Higher Appraised Amount is not more than
120% of the Lower Appraised Amount, the Liberty Media Group Private Market Value
(subject to any adjustment described in the second succeeding paragraph) will be
the average of those two amounts.  If the Higher Appraised Amount is more than
120% of the Lower Appraised Amount, the First Appraiser and the Second Appraiser
will agree upon and jointly designate the Mutually Designated Appraiser to
determine such private market value.  The Mutually Designated Appraiser will not
be provided with any of the work of the First Appraiser and the Second
Appraiser.  The Mutually Designated Appraiser will, no later than the 20th day
after the date the Mutually Designated Appraiser is designated, determine the
Mutually Appraised Amount, and the Liberty Media Group Private Market Value
(subject to any adjustment described in the second succeeding paragraph) will be
(i) if the Mutually Appraised Amount is between the Lower Appraised Amount and
the Higher Appraised Amount, (a) the average of (1) the Mutually Appraised
Amount and (2) the Lower Appraised Amount or the Higher Appraised Amount,
whichever is closer to the Mutually Appraised Amount, or (b) the Mutually
Appraised Amount, if neither the Lower Appraised Amount nor the Higher Appraised
Amount is closer to the Mutually Appraised Amount, or (ii) if the Mutually
Appraised Amount is greater than the Higher Appraised Amount or less than the
Lower Appraised Amount, the average of the Higher Appraised Amount and the Lower
Appraised Amount.  For these purposes, if any such investment banking firm
expresses its final view of the private market value of the Liberty Media Group
as a range of values, such investment banking firm's final view of such private
market value will be deemed to be the midpoint of such range of values.

     Each of the investment banking firms referred to in the immediately
preceding paragraph will be instructed to determine the private market value of
the Liberty Media Group as of the Appraisal Date based upon the amount a willing
purchaser would pay to a willing seller, in an arm's-length transaction, if it
were acquiring the Liberty Media Group, as if the Liberty Media Group were a
publicly traded non-controlled corporation and the purchaser was acquiring all
of the capital stock of such corporation and without consideration of any
potential regulatory constraints limiting the potential purchasers of the
Liberty Media Group other than that which would have existed if the Liberty
Media Group were a publicly traded non-controlled entity.

     Following the determination of the Liberty Media Group Private Market
Value, the investment banking firms whose final views of the private market
value of the Liberty Media Group were used in the calculation of the Liberty
Media Group Private Market Value will determine the Adjusted Outstanding Shares
of LMG Stock together with any further appropriate adjustments to the Liberty
Media Group Private Market Value resulting from such determination. The
"Adjusted Outstanding Shares of LMG Stock" means a number, as determined by such
investment banking firms as of the Appraisal Date, equal to the sum of the
number of shares of LMG Stock outstanding, the Number of Shares Issuable with
Respect to the Liberty Media Group Inter-Group Interest, the number of Committed
Acquisition Shares issuable, the number of shares of LMG Stock issuable upon the
conversion, exercise or exchange of all Pre-Distribution Convertible Securities
and the number of shares of LMG Stock issuable upon the conversion, exercise or
exchange of those Convertible Securities (other than Pre-Distribution
Convertible Securities and other than Convertible Securities which are
convertible into or exercisable or exchangeable for Committed Acquisition
Shares) the holders of which would derive an economic benefit from conversion,
exercise or exchange of such Convertible Securities which exceeds the economic
benefit of not converting, exercising or exchanging such Convertible Securities.
The "LMG Stock Per Share Value" means the quotient obtained by dividing the
Liberty Media Group Private Market Value by the Adjusted Outstanding Shares of
LMG Stock, provided that if such investment banking firms do not agree on the
determinations provided for in this paragraph, the LMG Stock Per Share Value
will be the average of the quotients so obtained on the basis of the respective
determinations of such firms.

     If TCI determines to convert shares of LMG Series A Stock into TCI Group
Series A Stock and shares of LMG Series B Stock into TCI Group Series B Stock at
the Liberty Media Group Optional Conversion Ratio, such conversion will occur on
a conversion date on or prior to the 120th day following the Appraisal Date.  If
TCI determines not to undertake such conversion, TCI may at any time thereafter
undertake to reestablish the LMG Stock Per Share Value as of a subsequent date.

     Any such conversion would dilute the interests of holders of TCI Group
Stock and would preclude holders of LMG Stock from retaining their interest in a
security reflecting separately the business of the Liberty Media Group. In
addition, the adjustments in respect of Pre-Distribution Convertible Securities
and Committed Acquisition Shares would dilute the interests of holders of LMG
Stock upon any conversion of shares of LMG Stock into TCI Group Stock at the
Liberty Media Group Optional Conversion Ratio.

     Conversion of TCIVG Stock at the Option of TCI.  The TCI Board may at any
time declare that (i) all of the outstanding shares of TCIVG Series A Stock will
be converted into a number (or fraction) of fully paid and nonassessable shares
of TCI Group Series A Stock equal to the TCI Ventures Group Optional Conversion
Ratio, and (ii) all of the outstanding shares of TCIVG Series B Stock will be
converted into a number (or fraction) of fully paid and nonassessable shares of
TCI Group Series B Stock equal to the TCI Ventures Group Optional Conversion
Ratio. As more fully described below, the TCI Ventures Group Optional Conversion
Ratio is the ratio of the private market value of a share of TCIVG Stock
determined by appraisal to the public trading price of a share of TCI Group
Stock.

     Under the TCI Charter, the "TCI Ventures Group Optional Conversion Ratio"
means the quotient (calculated to the nearest five decimal places) obtained by
dividing (x) the TCIVG Stock Per Share Value by (y) the average Market Value of
one share of TCI Group Series A Stock over the 20-Trading Day period ending on
the Trading Day preceding the Appraisal Date.   The TCIVG Stock Per Share Value
will equal the quotient obtained by dividing the TCI Ventures Group Private
Market Value by the Adjusted Outstanding Shares of TCIVG Stock, which will be
determined in the manner described below.

     The "TCI Ventures Group Private Market Value" means an amount equal to the
private market value of the TCI Ventures Group as of the Appraisal Date.  In the
event that TCI determines to establish the TCI Ventures Group Private Market
Value, TCI shall designate the First Appraiser and the Independent Committee
shall designate the Second Appraiser.  Not later than 20 days after the
Selection Date, the First Appraiser and the Second Appraiser will each determine
its initial view as to the private market value of the TCI Ventures Group as of
the Appraisal Date and will consult with one another with respect thereto.  Not
later than the 30th day after the Selection Date, the First Appraiser and the
Second Appraiser will each have determined its final view as to such private
market value.  If the Higher Appraised Amount is not more than 120% of the Lower
Appraised Amount, the TCI Ventures Group Private Market Value (subject to any
adjustment described in the second succeeding paragraph) will be the average of
those two 

                                       70
<PAGE>
 
amounts. If the Higher Appraised Amount is more than 120% of the Lower Appraised
Amount, the First Appraiser and the Second Appraiser will agree upon and jointly
designate the Mutually Designated Appraiser to determine such private market
value. The Mutually Designated Appraiser will not be provided with any of the
work of the First Appraiser and the Second Appraiser. The Mutually Designated
Appraiser will, no later than the 20th day after the date the Mutually
Designated Appraiser is designated, determine the Mutually Appraised Amount, and
the TCI Ventures Group Private Market Value (subject to any adjustment described
in the second succeeding paragraph) will be (i) if the Mutually Appraised Amount
is between the Lower Appraised Amount and the Higher Appraised Amount, (a) the
average of (1) the Mutually Appraised Amount and (2) the Lower Appraised Amount
or the Higher Appraised Amount, whichever is closer to the Mutually Appraised
Amount, or (b) the Mutually Appraised Amount, if neither the Lower Appraised
Amount nor the Higher Appraised Amount is closer to the Mutually Appraised
Amount, or (ii) if the Mutually Appraised Amount is greater than the Higher
Appraised Amount or less than the Lower Appraised Amount, the average of the
Higher Appraised Amount and the Lower Appraised Amount. For these purposes, if
any such investment banking firm expresses its final view of the private market
value of the TCI Ventures Group as a range of values, such investment banking
firm's final view of such private market value will be deemed to be the midpoint
of such range of values.

     Each of the investment banking firms referred to in the immediately
preceding paragraph will be instructed to determine the private market value of
the TCI Ventures Group as of the Appraisal Date based upon the amount a willing
purchaser would pay to a willing seller, in an arm's-length transaction, if it
were acquiring the TCI Ventures Group, as if the TCI Ventures Group were a
publicly traded non-controlled corporation and the purchaser was acquiring all
of the capital stock of such corporation and without consideration of any
potential regulatory constraints limiting the potential purchasers of the TCI
Ventures Group other than that which would have existed if the TCI Ventures
Group were a publicly traded non-controlled entity.

     Following the determination of the TCI Ventures Group Private Market Value,
the investment banking firms whose final views of the private market value of
the TCI Ventures Group were used in the calculation of the TCI Ventures Group
Private Market Value will determine the Adjusted Outstanding Shares of TCIVG
Stock together with any further appropriate adjustments to the TCI Ventures
Group Private Market Value resulting from such determination. The "Adjusted
Outstanding Shares of TCIVG Stock" means a number, as determined by such
investment banking firms as of the Appraisal Date, equal to the sum of the
number of shares of TCIVG Stock outstanding, the Number of Shares Issuable with
Respect to the TCI Ventures Group Inter-Group Interest, the number of shares of
TCIVG Stock issuable upon the conversion, exercise or exchange of all Pre-
Exchange Offer Securities, and the number of shares of TCIVG Stock issuable upon
the conversion, exercise or exchange of those Convertible Securities (other than
Pre-Exchange Offer Securities) the holders of which would derive an economic
benefit from conversion, exercise or exchange of such Convertible Securities
which exceeds the economic benefit of not converting, exercising or exchanging
such Convertible Securities.  The "TCIVG Stock Per Share Value" means the
quotient obtained by dividing the TCI Ventures Group Private Market Value by the
Adjusted Outstanding Shares of TCIVG Stock, provided that if such investment
banking firms do not agree on the determinations provided for in this paragraph,
the TCIVG Stock Per Share Value will be the average of the quotients so obtained
on the basis of the respective determinations of such firms.

     If TCI determines to convert shares of TCIVG Series A Stock into TCI Group
Series A Stock and shares of TCIVG Series B Stock into TCI Group Series B Stock
at the TCI Ventures Group Optional Conversion Ratio, such conversion will occur
on a conversion date on or prior to the 120th day following the Appraisal Date.
If TCI determines not to undertake such conversion, TCI may at any time
thereafter undertake to reestablish the TCIVG Stock Per Share Value as of a
subsequent date.

     Any such conversion would dilute the interests of holders of TCI Group
Stock and would preclude holders of TCIVG Stock from retaining their interest in
a security reflecting separately the business of the TCI Ventures Group. In
addition, the adjustments in respect of Pre-Exchange Offer Securities would
dilute the interests of holders  of TCIVG Stock upon any conversion of shares of
TCIVG Stock into TCI Group Stock at the TCI Ventures Group Optional Conversion
Ratio.

     Mandatory Dividend, Redemption or Conversion of LMG Stock.  Upon the
Disposition, in one transaction or a series of related transactions by TCI and
its subsidiaries of all or substantially all of the properties and assets of the
Liberty Media Group to one or more persons, entities or groups TCI is required,
on or prior to the 85th Trading Day 

                                       71
<PAGE>
 
following the consummation of such Disposition, to take one of the actions
listed in the following paragraph. This requirement does not apply to a
Disposition (a) in connection with the Disposition by TCI of all of TCI's
properties and assets in one transaction or a series of related transactions in
connection with the liquidation, dissolution or winding up of TCI, (b) by
dividend, other distribution or redemption in accordance with any provision
described under "--Conversion and Redemption--Redemption of LMG Stock in
Exchange for Stock of Subsidiary," "--Dividends," "--Share Distributions," or 
"--Liquidation Rights," (c) to any person, entity or group which TCI, directly
or indirectly, after giving effect to the Disposition, controls or (d) in
connection with a Related Business Transaction). For these purposes,
"substantially all of the properties and assets of the Liberty Media Group"
means a portion of such properties and assets that represents at least 80% of
the then-current market value (as determined by the TCI Board) of the properties
and assets of the Liberty Media Group as of such date.

     The action TCI is required to take is to either:

          (i)   subject to the limitations described under "--Dividends,"
     declare and pay a dividend in cash and/or securities or other property
     (other than a dividend or distribution of TCI Common Stock) to the holders
     of the outstanding shares of LMG Stock equally on a share for share basis
     (subject to the provisions described in the last sentence of the
     penultimate paragraph under this caption "--Mandatory Dividend, Redemption
     or Conversion of LMG Stock"), in an aggregate amount equal to the product
     of the Liberty Media Group Outstanding Interest Fraction as of the record
     date for determining the holders entitled to receive such dividend and the
     Liberty Media Group Net Proceeds;

          (ii)  provided that there are assets of TCI legally available therefor
     and the Liberty Media Group Available Dividend Amount would have been
     sufficient to pay a dividend in lieu thereof as described in clause (i) of
     this paragraph, then:

                (A) if such Disposition involves all (not merely substantially
          all) of the properties and assets of the Liberty Media Group, redeem
          all outstanding shares of LMG Series A Stock and LMG Series B Stock in
          exchange for cash and/or securities or other property (other than TCI
          Common Stock) in an aggregate amount equal to the product of the
          Adjusted Liberty Media Group Outstanding Interest Fraction as of the
          date of such redemption and the Liberty Media Group Net Proceeds, such
          aggregate amount to be allocated (subject to the provisions described
          in the last sentence of the penultimate paragraph under this caption)
          to shares of LMG Series A Stock and LMG Series B Stock in the ratio of
          the number of shares of each such series outstanding (so that the
          amount of consideration paid for the redemption of each share of LMG
          Series A Stock and each share of LMG Series B Stock is the same); or

                (B) if such Disposition involves substantially all (but not all)
          of the properties and assets of the Liberty Media Group, apply an
          aggregate amount of cash and/or securities or other property (other
          than TCI Common Stock) equal to the product of the Liberty Media Group
          Outstanding Interest Fraction as of the date shares are selected for
          redemption and the Liberty Media Group Net Proceeds of such
          Disposition to the redemption of outstanding shares of LMG Series A
          Stock and LMG Series B Stock, such aggregate amount to be allocated
          (subject to the provisions described in the last sentence of the
          penultimate paragraph under this caption) to shares of LMG Series A
          Stock and LMG Series B Stock in the ratio of the number of shares of
          each such series outstanding, and the number of shares of each such
          series to be redeemed to equal the lesser of (x) the whole number
          nearest the number determined by dividing the aggregate amount so
          allocated to the redemption of such series by the average Market Value
          of one share of LMG Series A Stock during the ten-Trading Day period
          beginning on the 16th Trading Day following the consummation of such
          Disposition and (y) the number of shares of such series outstanding
          (so that the amount of consideration paid for the redemption of each
          share of LMG Series A Stock and each share of LMG Series B Stock is
          the same); or

          (iii) convert (A) each outstanding share of LMG Series A Stock into a
     number (or fraction) of fully paid and nonassessable shares of TCI Group
     Series A Stock and (B) each outstanding share of LMG 

                                       72
<PAGE>
 
     Series B Stock into a number (or fraction) of fully paid and nonassessable
     shares of TCI Group Series B Stock, in each case equal to 110% of the
     average daily ratio (calculated to the nearest five decimal places) of the
     Market Value of one share of LMG Series A Stock to the Market Value of one
     share of TCI Group Series A Stock during the ten-Trading Day period
     referred to in clause (ii)(B) of this paragraph.

     TCI may elect to pay the dividend or redemption price referred to in clause
(i) or (ii) of the second paragraph under this caption "--Mandatory Dividend,
Redemption or Conversion or LMG Stock" either in the same form as the proceeds
of the Disposition were received or in any other combination of cash or
securities or other property (other than TCI Common Stock) that the TCI Board
determines will have an aggregate market value on a fully distributed basis, of
not less than the amount of the Liberty Media Group Net Proceeds.  If the
dividend or redemption price is paid in the form of securities of an issuer
other than TCI, the TCI Board may determine either to (i) pay the dividend or
redemption price in the form of separate classes or series of securities, with
one class or series of such securities to holders of LMG Series A Stock and
another class or series of securities to holders of LMG Series B Stock, provided
that such securities (and, if such securities are convertible into or
exercisable or exchangeable for shares of another class or series of securities,
the securities so issuable upon such conversion, exercise or exchange) do not
differ in any respect other than their relative voting rights and related
differences in designation, conversion, redemption and share distribution
provisions, with holders of shares of LMG Series B Stock receiving the class or
series having the higher relative voting rights (without regard to whether such
rights differ to a greater or lesser extent than the corresponding differences
in voting rights, designation, conversion, redemption and share distribution
provisions between the LMG Series A Stock and the LMG Series B Stock), provided
that if such securities constitute capital stock of a Subsidiary of TCI, such
rights will not differ to a greater extent than the corresponding differences in
voting rights, designation, conversion, redemption and share distribution
provisions between the LMG Series A Stock and the LMG Series B Stock, and
otherwise such securities will be distributed on an equal per share basis, or
(ii) pay the dividend or redemption price in the form of a single class of
securities without distinction between the shares received by the holders of LMG
Series A Stock and LMG Series B Stock.  The Related Business Transaction
exception to the foregoing requirements would enable TCI to enter into
transactions in which the properties or assets of the Liberty Media Group may be
considered to be "disposed of" in exchange for equity securities of an entity
engaged or proposing to engage in similar or complementary business areas to
those of the Liberty Media Group while maintaining the capital structure and
delineation of business groups of the Liberty Media Group.

     The effect of using the Adjusted Liberty Media Group Outstanding Interest
Fraction, instead of the Liberty Media Group Outstanding Interest Fraction, in
the determination of amounts to be paid in redemption of shares of LMG Stock
following a Disposition of all of the properties and assets of the Liberty Media
Group is to allocate to the TCI Group a portion of the Liberty Media Group Net
Proceeds of the Disposition, in addition to the amount so allocated in respect
of any Inter-Group Interest, sufficient to provide for the delivery of the
portion of the consideration deliverable by TCI upon any post-Disposition
conversion, exercise or exchange of Pre-Distribution Convertible Securities that
is in substitution for shares of LMG Stock that would have been issuable upon
such conversion, exercise or exchange if it had occurred prior to such
Distribution and to make similar provision for TCI's obligation in respect of
any Committed Acquisition Shares that remain issuable.  To the extent such Pre-
Distribution Convertible Securities and Committed Acquisition Shares are
included in the determination of the Adjusted Liberty Media Group Outstanding
Interest Fraction, TCI's obligations in respect of such securities would not be
a reduction in the calculation of the Liberty Media Group Net Proceeds.  In the
event any redemption of the LMG Stock or conversion of the LMG Stock into TCI
Group Stock is made in circumstances in which securities or property are
allocated to the TCI Group in respect of Pre-Distribution Convertible
Securities, Committed Acquisition Shares or other Convertible Securities
entitled to receive such securities or property upon conversion, exercise or
exchange, the TCI Group will segregate and hold such securities or other
property separate (in the case of any securities or property other than TCI
Group Stock), or duly reserve shares of TCI Group Stock issuable upon such
conversion, exercise or exchange, for the benefit of the holders of Pre-
Distribution Convertible Securities, Committed Acquisition Shares or other
Convertible Securities.  In the event the holders of any such Pre-Distribution
Convertible Securities or other Convertible Securities do not convert, exercise
or exchange such securities prior to the expiration of any conversion or
exercise right or the retirement of such security, or the acquisition relating
to such Committed Acquisition Shares is not consummated (or any Convertible
Securities which are convertible into or exercisable or exchangeable for
Committed Acquisition Shares are not converted, exercised or exchanged), then
the securities or other property so reserved shall revert to the TCI Group and
the former holders of LMG Stock shall have no interest in such securities or
property.

                                       73
<PAGE>
 
     At the time of any dividend made as a result of a Disposition referred to
above, the TCI Group will be credited, and the Liberty Media Group will be
charged (in addition to the charge for the dividend paid in respect of
outstanding shares of LMG Stock), with an amount equal to the product of (i) the
aggregate amount paid in respect of such dividend times (ii) a fraction the
numerator of which is the Liberty Media Group Inter-Group Interest Fraction and
the denominator of which is the Liberty Media Group Outstanding Interest
Fraction.

     The option to convert the LMG Stock into TCI Group Stock in the event of a
Disposition provides TCI with additional flexibility by allowing TCI to deliver
consideration in the form of shares of TCI Group Stock rather than cash or
securities or other properties.  This alternative could be used, for example, in
circumstances when TCI did not have sufficient legally available assets under
the DGCL to pay the full amount of an otherwise required dividend or redemption
or when TCI desired to retain such proceeds.

     If less than substantially all of the properties and assets of the Liberty
Media Group were disposed of by TCI in one transaction, TCI would not be
required to pay a dividend on, redeem or convert the outstanding shares of LMG
Stock, even if an additional transaction were consummated at a later time in
which additional properties and assets of the Liberty Media Group were disposed
of by TCI, which, together with the properties and assets disposed of in the
first transaction, would have constituted substantially all of the properties
and assets of the Liberty Media Group at the time of the first transaction,
unless such transactions constituted a series of related transactions.  The
second transaction, however, could trigger such a requirement if, at the time of
the second transaction, the properties and assets disposed of in such
transaction constituted at least substantially all of the properties and assets
of the Liberty Media Group at such time.  If less than substantially all of the
properties and assets of the Liberty Media Group were disposed of by TCI, the
holders of the LMG Stock would not be entitled to receive any dividend or have
their shares redeemed or converted for TCI Group Stock, although the TCI Board
could determine, in its sole discretion, to pay a dividend on the LMG Stock in
an amount related to the proceeds of such Disposition.

     Mandatory Dividend, Redemption or Conversion of TCIVG Stock.  Upon the
Disposition in one transaction or a series of related transactions by TCI and
its subsidiaries of all or substantially all of the properties and assets of the
TCI Ventures Group to any one or more persons, entities or groups, TCI is
required, on or prior to the 85th Trading Day following the consummation of such
Disposition, to take one of the actions listed in the following paragraph.  This
requirement does not apply to a Disposition (a) in connection with the
Disposition by TCI of all of TCI's properties and assets in one transaction or a
series of related transactions in connection with the liquidation, dissolution
or winding up of TCI, (b) by dividend, other distribution or redemption in
accordance with any provision described under "--Conversion and Redemption--
Redemption of TCIVG Stock in Exchange for Stock of Subsidiary" "--Dividends," "-
- -Share Distributions," or "--Liquidation Rights," (c) to any person, entity or
group which TCI, directly or indirectly, after giving effect to the Disposition,
controls or (d) in connection with a Related Business Transaction).  For these
purposes, "substantially all of the properties and assets of the TCI Ventures
Group" means a portion of such properties and assets that represents at least
80% of the then-current market value (as determined by the TCI Board) of the
properties and assets of the TCI Ventures Group as of such date.

          The action TCI is required to take is to either:

          (i)  subject to the limitations described above under "--Dividends,"
     declare and pay a dividend in cash and/or securities or other property
     (other than a dividend or distribution of TCI Common Stock) to the holders
     of the outstanding shares of TCIVG Stock equally on a share for share basis
     (subject to the provisions described in the second sentence of the third
     paragraph under this caption "--Mandatory Dividends, Redemption or
     Conversion of TCIVG Stock"), in an aggregate amount equal to the product of
     the TCI Ventures Group Outstanding Interest Fraction as of the record date
     for determining the holders entitled to receive such dividend and the TCI
     Ventures Group Net Proceeds of such Disposition;

          (ii) provided that there are assets of TCI legally available therefor
     and the TCI Ventures Group Available Dividend Amount would have been
     sufficient to pay a dividend in lieu thereof as described in clause (i) of
     this paragraph, then:

                                       74
<PAGE>
 
                (A) if such Disposition involves all (not merely substantially
          all) of the properties and assets of the TCI Ventures Group, redeem
          all outstanding shares of TCIVG Series A Stock and TCIVG Series B
          Stock in exchange for cash and/or securities or other property (other
          than TCI Common Stock) in an aggregate amount equal to the product of
          the Adjusted TCI Ventures Group Outstanding Interest Fraction as of
          the date of such redemption and the TCI Ventures Group Net Proceeds of
          such Disposition, such aggregate amount to be allocated (subject to
          the provisions described in the second sentence of the following
          paragraph) to shares of TCIVG Series A Stock and TCIVG Series B Stock
          in the ratio of the number of shares of each such series outstanding
          (so that the amount of consideration paid for the redemption of each
          share of TCIVG Series A Stock and each share of TCIVG Series B Stock
          is the same); or

                (B) if such Disposition involves substantially all (but not all)
          of the properties and assets of the TCI Ventures Group, apply an
          aggregate amount of cash and/or securities or other property (other
          than TCI Common Stock) equal to the product of the TCI Ventures Group
          Outstanding Interest Fraction as of the date shares are selected for
          redemption and the TCI Ventures Group Net Proceeds of such Disposition
          to the redemption of outstanding shares of TCIVG Series A Stock and
          TCIVG Series B Stock, such aggregate amount to be allocated (subject
          to the provisions described in the second sentence of the following
          paragraph) to shares of TCIVG Series A Stock and TCIVG Series B Stock
          in the ratio of the number of shares of each such series outstanding,
          with the number of shares of each such series to be redeemed to equal
          the lesser of (x) the whole number nearest the number determined by
          dividing the aggregate amount so allocated to the redemption of such
          series by the average Market Value of one share of TCIVG Series A
          Stock during the ten-Trading Day period beginning on the 16th Trading
          Day following the consummation of such Disposition and (y) the number
          of shares of such series outstanding (so that the amount of
          consideration paid for the redemption of each share of TCIVG Series A
          Stock and each share of TCIVG Series B Stock is the same); or

          (iii) convert (A) each outstanding share of TCIVG Series A Stock into
     a number (or fraction) of fully paid and nonassessable shares of TCI Group
     Series A Stock and (B) each outstanding share of TCIVG Series B Stock into
     a number (or fraction) of fully paid and nonassessable shares of TCI Group
     Series B Stock, in each case equal to 110% of the average daily ratio
     (calculated to the nearest five decimal places) of the Market Value of one
     share of TCIVG Series A Stock to the Market Value of one share of TCI Group
     Series A Stock during the ten-Trading Day period referred to in clause
     (ii)(B) of this paragraph.

     TCI may elect to pay the dividend or redemption price referred to in clause
(i) or (ii) of the second paragraph under this caption "--Mandatory Dividend,
Redemption or Conversion of TCIVG Stock" either in the same form as the proceeds
of the Disposition were received or in any other combination of cash or
securities or other property (other than TCI Common Stock) that the TCI Board
determines will have an aggregate market value on a fully distributed basis, of
not less than the amount of the TCI Ventures Group Net Proceeds.  If the
dividend or redemption price is paid in the form of securities of an issuer
other than TCI, the TCI Board may determine either to (i) pay the dividend or
redemption price in the form of separate classes or series of securities, with
one class or series of such securities to holders of TCIVG Series A Stock and
another class or series of securities to holders of TCIVG Series B Stock,
provided that such securities (and, if such securities are convertible into or
exercisable or exchangeable for shares of another class or series of securities,
the securities so issuable upon such conversion, exercise or exchange) do not
differ in any respect other than their relative voting rights and related
differences in designation, conversion, redemption and share distribution
provisions, with holders of shares of TCIVG Series B Stock receiving the class
or series having the higher relative voting rights (without regard to whether
such rights differ to a greater or lesser extent than the corresponding
differences in voting rights, designation, conversion, redemption and share
distribution provisions between the TCIVG Series A Stock and the TCIVG Series B
Stock), provided that if such securities constitute capital stock of a
Subsidiary of TCI, such rights will not differ to a greater extent than the
corresponding differences in voting rights, designation, conversion, redemption
and share distribution provisions between the TCIVG Series A Stock and the TCIVG
Series B Stock, and otherwise such securities will be distributed on an equal
per share basis, or (ii) pay the dividend or redemption price in the form of a
single class of securities without distinction between the shares received by
the holders of TCIVG Series A Stock and TCIVG Series B Stock.   The Related
Business Transaction exception to the foregoing requirements would 

                                       75
<PAGE>
 
enable TCI to enter into transactions in which the properties or assets of the
TCI Ventures Group may be considered to be "disposed of" in exchange for equity
securities of an entity engaged or proposing to engage in similar or
complementary business areas to those of the TCI Ventures Group while
maintaining the capital structure and delineation of business groups of the TCI
Ventures Group.

     The effect of using the Adjusted TCI Ventures Group Outstanding Interest
Fraction, instead of the TCI Ventures Group Outstanding Interest Fraction, in
the determination of amounts to be paid in redemption of shares of TCIVG Stock
following a Disposition of all of the properties and assets of the TCI Ventures
Group is to allocate to the TCI Group a portion of the TCI Ventures Group Net
Proceeds of the Disposition, in addition to the amount so allocated in respect
of any Inter-Group Interest, sufficient to provide for the delivery of the
portion of the consideration deliverable by TCI upon any post-Disposition
conversion, exercise or exchange of Pre-Exchange Offer Securities that is in
substitution for shares of TCIVG Stock that would have been issuable upon such
conversion, exercise or exchange if it had occurred prior to such Disposition.
To the extent such Pre-Exchange Offer Securities are included in the
determination of the Adjusted TCI Ventures Group Outstanding Interest Fraction,
TCI's obligations in respect of such securities would not be a reduction in the
calculation of the TCI Ventures Group Net Proceeds.  In the event any redemption
of the TCIVG Stock or conversion of the TCIVG Stock into TCI Group Stock is made
in circumstances in which securities or property are allocated to the TCI Group
in respect of Pre-Exchange Offer Securities or other Convertible Securities
entitled to receive such securities or property upon conversion, exercise or
exchange, the TCI Group will segregate and hold such securities or other
property separate (in the case of any securities or property other than TCI
Group Stock), or duly reserve shares of TCI Group Stock issuable upon such
conversion, exercise or exchange, for the benefit of the holders of Pre-Exchange
Offer Securities or other Convertible Securities.   In the event the holders of
any such Pre-Exchange Offer Securities or other Convertible Securities do not
convert, exercise or exchange such securities prior to the expiration of any
conversion, exercise or exchange right or the retirement of such security, then
the securities or other property so reserved shall revert to the TCI Group and
the former holders of TCIVG Stock shall have no interest in such securities or
property.

     At the time of any dividend made as a result of a Disposition referred to
above, the TCI Group will be credited, and the TCI Ventures Group will be
charged (in addition to the charge for the dividend paid in respect of
outstanding shares of TCIVG Stock), with an amount equal to the product of (i)
the aggregate amount paid in respect of such dividend times (ii) a fraction the
numerator of which is the TCI Ventures Group Inter-Group Interest Fraction and
the denominator of which is the TCI Ventures Group Outstanding Interest
Fraction.

     The option to convert the TCIVG Stock into TCI Group Stock in the event of
a Disposition provides TCI with additional flexibility by allowing TCI to
deliver consideration in the form of shares of TCI Group Stock rather than cash
or securities or other properties.  This alternative could be used, for example,
in circumstances when TCI did not have sufficient legally available assets under
the DGCL to pay the full amount of an otherwise required dividend or redemption
or when TCI desired to retain such proceeds.

     If less than substantially all of the properties and assets of the TCI
Ventures Group were disposed of by TCI in one transaction, TCI would not be
required to pay a dividend on, redeem or convert the outstanding shares of TCIVG
Stock, even if an additional transaction were consummated at a later time in
which additional properties and assets of the TCI Ventures Group were disposed
of by TCI, which, together with the properties and assets disposed of in the
first transaction, would have constituted substantially all of the properties
and assets of the TCI Ventures Group at the time of the first transaction,
unless such transactions constituted a series of related transactions.  The
second transaction, however, could trigger such a requirement if, at the time of
the second transaction, the properties and assets disposed of in such
transaction constituted at least substantially all of the properties and assets
of the TCI Ventures Group at such time.  If less than substantially all of the
properties and assets of the TCI Ventures Group were disposed of by TCI, the
holders of the TCIVG Stock would not be entitled to receive any dividend or have
their shares redeemed or converted for TCI Group Stock, although the TCI Board
could determine, in its sole discretion, to pay a dividend on the TCIVG Stock in
an amount related to the proceeds of such Disposition.

     Redemption of LMG Stock in Exchange for Stock of Subsidiary.  At any time
at which all of the assets and liabilities attributed to the Liberty Media Group
have become and continue to be held directly or indirectly by any one or more
corporations that are Qualifying Subsidiaries (the "Liberty Media Group
Subsidiaries"), the TCI Board may, 

                                       76
<PAGE>
 
subject to the availability of assets of TCI legally available therefor, redeem,
on a pro rata basis, all of the outstanding shares of LMG Stock in exchange for
an aggregate number of outstanding fully paid and nonassessable shares of common
stock of each Liberty Media Group Subsidiary equal to the product of the
Adjusted Liberty Media Group Outstanding Interest Fraction and the number of
outstanding shares of common stock of such Liberty Media Group Subsidiary that
are owned by TCI. The effect of using the Adjusted Liberty Media Group
Outstanding Interest Fraction, instead of the Liberty Media Group Outstanding
Interest Fraction, in the determination of the number of shares of the Liberty
Media Group Subsidiaries deliverable in such a redemption is to allocate to the
TCI Group a portion of the shares of the Liberty Media Group Subsidiaries, in
addition to the number of such shares so allocated in respect of any Inter-Group
Interest, sufficient to provide for the delivery of the consideration
deliverable by TCI upon any post-redemption conversion, exercise or exchange of
Pre-Distribution Convertible Securities that become so payable in substitution
for shares of LMG Stock that would have been issuable upon such conversion,
exercise or exchange if it had occurred prior to such redemption and to make
similar provision for TCI's obligations in respect of any Committed Acquisition
Shares that remain issuable.

     In effecting such a redemption, the TCI Board may determine either to (i)
redeem shares of LMG Series A Stock and LMG Series B Stock in exchange for
shares of separate classes or series of common stock of each Liberty Media Group
Subsidiary with relative voting rights and related differences in designation,
conversion, redemption and share distribution provisions not greater than the
corresponding differences in voting rights, designation, conversion, redemption
and share distribution provisions between the LMG Series A Stock and LMG Series
B Stock, with holders of shares of LMG Series B Stock receiving the class or
series having the higher relative voting rights, or (ii) redeem shares of LMG
Series A Stock and LMG Series B Stock in exchange for shares of a single class
of common stock of each Liberty Media Group Subsidiary without distinction
between the shares distributed to the holders of the two series of LMG Stock.
If TCI determines to undertake a redemption as described in clause (i) of the
preceding sentence, the outstanding shares of common stock of each Liberty Media
Group Subsidiary not distributed to holders of LMG Stock shall consist solely of
the class or series having the lower relative voting rights.

     Redemption of TCIVG Stock in Exchange for Stock of Subsidiary.  At any time
at which all of the assets and liabilities attributed to the TCI Ventures Group
have become and continue to be held directly or indirectly by any one or more
corporations that are Qualifying Subsidiaries (the "TCI Ventures Group
Subsidiaries"), the TCI Board may, subject to the availability of assets of TCI
legally available therefor, redeem on a pro rata basis, all of the outstanding
shares of TCIVG Stock in exchange for an aggregate number of outstanding, fully
paid and nonassessable shares of common stock of each TCI Ventures Group
Subsidiary equal to the product of the Adjusted TCI Ventures Group Outstanding
Interest Fraction and the number of outstanding shares of common stock of such
TCI Ventures Group Subsidiary that are owned by TCI.  The effect of using the
Adjusted TCI Ventures Group Outstanding Interest Fraction, instead of the TCI
Ventures Group Outstanding Interest Fraction, in the determination of the number
of shares of the TCI Ventures Group Subsidiaries deliverable in such a
redemption is to allocate to the TCI Group a portion of the shares of the TCI
Ventures Group Subsidiaries, in addition to the number of such shares so
allocated in respect of any Inter-Group Interest, sufficient to provide for the
delivery of the consideration deliverable by TCI upon any post-redemption
conversion, exercise or exchange of Pre-Exchange Offer Securities that become so
payable in substitution for shares of TCIVG Stock that would have been issuable
upon such conversion, exercise or exchange if it had occurred prior to such
redemption.

     In effecting such a redemption, the TCI Board may determine either to (i)
redeem shares of TCIVG Series A Stock and TCIVG Series B Stock in exchange for
shares of separate classes or series of common stock of each TCI Ventures Group
Subsidiary with relative voting rights and related differences in designation,
conversion, redemption and share distribution provisions not greater than the
corresponding differences in voting rights, designation, conversion, redemption
and share distribution provisions between the TCIVG Series A Stock and TCIVG
Series B Stock, with holders of shares of TCIVG Series B Stock receiving the
class or series having the higher relative voting rights, or (ii) redeem shares
of TCIVG Series A Stock and TCIVG Series B Stock in exchange for shares of a
single class of common stock of each TCI Ventures Group Subsidiary without
distinction between the shares distributed to the holders of the two series of
TCIVG Stock.

     Certain Provisions Respecting Convertible Securities.  Unless the
provisions of any class or series of Pre-Distribution Convertible Securities or
Convertible Securities which are convertible into or exercisable or 

                                       77
<PAGE>
 
exchangeable for Committed Acquisition Shares provide specifically to the
contrary, after any conversion date or redemption date on which all outstanding
shares of LMG Stock were converted or redeemed, any share of LMG Stock that is
issued on conversion, exercise or exchange of any Pre-Distribution Convertible
Securities or any Convertible Securities which are convertible into or
exercisable or exchangeable for Committed Acquisition Shares will, immediately
upon issuance pursuant to such conversion, exercise or exchange and without any
notice or any other action on the part of TCI or the TCI Board or the holder of
such share of LMG Stock, be converted into or redeemed in exchange for, as
applicable, the kind and amount of shares of capital stock, cash and/or other
securities or property that a holder of such Pre-Distribution Convertible
Securities or any Convertible Securities which are convertible into or
exercisable or exchangeable for Committed Acquisition Shares would have been
entitled to receive as a result of such conversion and redemption had such
securities been converted, exercised or exchanged immediately prior to such
action. With respect to any Convertible Securities that are convertible into or
exercisable or exchangeable for shares of LMG Stock and which are created,
established or otherwise first authorized for issuance subsequent to the record
date for the LMG Distribution (other than Pre-Distribution Convertible
Securities and Convertible Securities which are convertible into or exercisable
or exchangeable for Committed Acquisition Shares), the terms and provisions of
which do not provide for adjustments specifying the kind and amount of capital
stock, cash and/or securities or other property that such holder would be
entitled to receive upon the conversion, exercise or exchange of such
Convertible Securities following any conversion date or redemption date on which
all outstanding shares of LMG Stock were converted or redeemed, then upon such
conversion, exercise or exchange of such Convertible Securities, any share of
LMG Stock that is issued on conversion, exercise or exchange of any such
Convertible Securities will, immediately upon issuance and without any notice or
any other action on the part of TCI or the TCI Board or the holder of such share
of LMG Stock, be redeemed in exchange for, to the extent assets of TCI are
legally available therefor, the amount of $.01 per share in cash.

     Unless the provisions of the Pre-Exchange Offer Securities provide
specifically to the contrary, after any conversion date or redemption date on
which all outstanding shares of TCIVG Stock were converted or redeemed, any
share of TCIVG Stock that is issued on conversion, exercise or exchange of any
Pre-Exchange Offer Securities will, immediately upon issuance pursuant to such
conversion, exercise or exchange and without any notice or any other action on
the part of TCI or the TCI Board or the holder of such share of TCIVG Stock, be
converted into or redeemed in exchange for, as applicable, the kind and amount
of shares of capital stock, cash and/or securities or other property that a
holder of such Pre-Exchange Offer Securities would have been entitled to receive
as a result of such conversion and redemption had such Pre-Exchange Offer
Securities been converted, exercised or exchanged immediately prior to such
action.  Unless the provisions of any class or series of Convertible Securities
(other than Pre-Exchange Offer Securities) which are convertible into or
exercisable or exchangeable for shares of TCIVG Stock provide specifically to
the contrary, after any conversion date or redemption date on which all
outstanding shares of TCIVG Stock were converted or redeemed, any share of TCIVG
Stock that is issued on conversion, exercise or exchange of any such Convertible
Securities will, immediately upon issuance pursuant to such conversion, exercise
or exchange and without any notice or any other action on the part of TCI or the
TCI Board or the holder of such share of TCIVG Stock, be redeemed in exchange
for, to the extent assets of TCI are legally available therefor, the amount of
$.01 per share in cash.

     In the event of any conversion as described above under "--Conversion and
Redemption--Conversion of LMG Stock at the Option of TCI" or "--Conversion and

shares of LMG Stock will be converted, (ii) the conversion date (which will not
be more than 85 Trading Days following the consummation of such Disposition in

into or for which outstanding Convertible Securities are then convertible,

thereof.  Such notice will be sent not less than 35 Trading Days nor more than
45 Trading Days prior to the conversion date.

     If TCI determines to redeem shares of LMG Series A Stock and LMG Series B
Stock as described above under "--Conversion and Redemption--Redemption of LMG
Stock in Exchange for Stock of Subsidiary," TCI will promptly cause to be given
to each holder of LMG Series A Stock and LMG Series B Stock a notice setting
forth (i) a statement that all outstanding shares of LMG Stock will be redeemed
in exchange for shares of common stock of the Liberty Media Group Subsidiaries,
(ii) the redemption date, (iii) the Adjusted Liberty Media Group Outstanding
Interest Fraction as of a recent date preceding the date of such notice, (iv)
the place or places where certificates for shares of LMG Stock, properly
endorsed or assigned for transfer (unless TCI waives such requirement), are to
be surrendered for delivery of certificates for shares of common stock of the
Liberty Media Group Subsidiaries, and  (v) the number of outstanding shares of
LMG Series A Stock and LMG Series B Stock and the number of shares of LMG Series
A Stock and LMG Series B Stock into or for which outstanding Convertible
Securities are then convertible, exercisable or exchangeable and the conversion,
exercise or exchange prices thereof (and stating which, if any, of such
Convertible Securities constitute Pre-Distribution Convertible Securities or
Convertible Securities which are convertible into or exercisable or exchangeable
for Committed Acquisition Shares) and the number of Committed Acquisition Shares
issuable.  Such notice will be sent not less than 35 Trading Days nor more than
45 Trading Days prior to the redemption date.

     In each case in which a notice is required to be given to holders of
outstanding shares of LMG Series A Stock and LMG Series B Stock in accordance
with the preceding five paragraphs (other than a notice to holders of shares
selected for redemption), notice shall also be given, within the required time
period, to each holder of Convertible Securities that are convertible into or
exercisable or exchangeable for shares of either such series (unless provision
for such notice is otherwise made pursuant to the terms of such Convertible
Securities), which notice shall include, in addition to all of the information
set forth in the corresponding notice to holders of LMG Stock, a statement to
the effect that the holders of such Convertible Securities will be entitled to
receive the dividend, participate in the redemption of shares following a
Disposition or in the selection of shares for redemption, participate in the
conversion of shares or participate in the redemption of shares in exchange for
stock of the Liberty Media Group Subsidiaries only if such holder appropriately
converts, exercises or exchanges such Convertible Securities on or prior to the
record date for the dividend, redemption date, date fixed for selection of
shares to be redeemed or conversion date, as applicable, set forth in such
notice.  In the case of a redemption or conversion of shares of LMG Stock, the
notice to holders of Convertible Securities shall also state what, if anything,
such holders will be entitled to receive pursuant to the terms of such

                                       80
<PAGE>
 
Convertible Securities or, if applicable, the provision described under "--
Conversion and Redemption--Certain Provisions Respecting Convertible Securities"
if such holders convert, exercise or exchange such Convertible Securities
following the redemption date or conversion date, as applicable.

     All notices required to be given in accordance with the preceding
paragraphs will be sent to a holder by first-class mail, postage prepaid, at the
holder's address as the same appears on the transfer books of TCI.  Neither the
failure to mail any notice to any particular holder of LMG Stock or of
Convertible Securities nor any defect therein will affect the sufficiency
thereof with respect to any other holder of outstanding shares of LMG Stock or
of Convertible Securities, or the validity of any conversion or redemption.

     TCI will not be required to issue or deliver fractional shares of any class
of capital stock or any fractional securities to any holder of LMG Stock upon
any conversion, redemption, dividend or other distribution described above. In
connection with the determination of the number of shares of any class of
capital stock that is issuable or the amount of securities that is deliverable
to any holder of record upon any such conversion, redemption, dividend or other
distribution (including any fractions of shares or securities), TCI may
aggregate the number of shares of LMG Stock held at the relevant time by such
holder of record.  If the number of shares of any class of capital stock or the
amount of securities remaining to be issued or delivered to any holder of LMG
Stock is a fraction, TCI will, if such fraction is not issued or delivered to
such holder, pay a cash adjustment in respect of such fraction in an amount
equal to the fair market value of such fraction on the fifth Trading Day prior
to the date such payment is to be made (without interest). For purposes of the
preceding sentence, "fair market value" of any fraction will be (i) in the case
of any fraction of a share of capital stock of TCI, the product of such fraction
and the Market Value of one share of such capital stock and (ii) in the case of
any other fractional security, such value as is determined by the TCI Board.

     No adjustments in respect of dividends will be made upon the conversion or
redemption of any shares of LMG Stock; provided, however, that if the conversion
date or the redemption date with respect to the LMG Stock is subsequent to the
record date for the payment of a dividend or other distribution thereon or with
respect thereto, the holders of shares of LMG Stock at the close of business on
such record date will be entitled to receive the dividend or other distribution
payable on or with respect to such shares on the date set for payment of such
dividend or other distribution, notwithstanding the conversion or redemption of
such shares or TCI's default in payment of the dividend or distribution due on
such date.

     Before any holder of shares of LMG Stock will be entitled to receive
certificates representing shares of any kind of capital stock or cash and/or
securities or other property to be received by such holder with respect to any
conversion or redemption of shares of LMG Stock, such holder is required to
surrender at such place as TCI will specify certificates for such shares,
properly endorsed or assigned for transfer (unless TCI waives such requirement).
TCI will as soon as practicable after surrender of certificates representing
shares of LMG Stock deliver to the person for whose account such shares were so
surrendered, or to the nominee or nominees of such person, certificates
representing the number of whole shares of the kind of capital stock or cash
and/or securities or other property to which such person is entitled, together
with any payment for fractional securities referred to above.  If less than all
of the shares of LMG Stock represented by any one certificate are to be
redeemed, TCI will issue and deliver a new certificate for the shares of LMG
Stock not redeemed.  TCI will not be required to register a transfer of (i) any
shares of LMG Stock for a period of 15 Trading Days next preceding any selection
of shares of LMG Stock to be redeemed or (ii) any shares of LMG Stock selected
or called for redemption.  Shares selected for redemption may not thereafter be
converted pursuant to the provisions described under "--Conversion at the Option
of the Holder."

     From and after any applicable conversion date or redemption date, all
rights of a holder of shares of LMG Stock that were converted or redeemed will
cease except for the right, upon surrender of the certificates representing
shares of LMG Stock, to receive certificates representing shares of the kind and
amount of capital stock or cash and/or securities or other property for which
such shares were converted or redeemed, together with any payment for fractional
securities, and such holder will have no other or further rights in respect of
the shares of LMG Stock so converted or redeemed, including, but not limited to,
any rights with respect to any cash, securities or other property which are
reserved or otherwise designated by TCI as being held for the satisfaction of
TCI's obligations to pay or deliver any cash, securities or other property upon
the conversion, exercise or exchange of any Convertible Securities outstanding
as of the date of such conversion or redemption or any Committed Acquisition
Shares which may then be issuable.  No 

                                       81
<PAGE>
 
holder of a certificate that, immediately prior to the applicable conversion
date or redemption date for the LMG Stock, represented shares of LMG Stock will
be entitled to receive any dividend or other distribution with respect to shares
of any kind of capital stock into or in exchange for which the LMG Stock was
converted or redeemed until surrender of such holder's certificate for a
certificate or certificates representing shares of such kind of capital stock.
Upon such surrender, there will be paid to the holder the amount of any
dividends or other distributions (without interest) which theretofore became
payable with respect to a record date after the conversion date or redemption
date, as the case may be, but that were not paid by reason of the foregoing,
with respect to the number of whole shares of the kind of capital stock
represented by the certificate or certificates issued upon such surrender. From
and after a conversion date or redemption date, as the case may be, of LMG
Stock, TCI will, however, be entitled to treat the certificates for shares of
LMG Stock that have not yet been surrendered for conversion or redemption as
evidencing the ownership of the number of whole shares of the kind or kinds of
capital stock for which the shares of LMG Stock represented by such certificates
have been converted or redeemed, notwithstanding the failure to surrender such
certificates.

     TCI will pay any and all documentary, stamp or similar issue or transfer
taxes that may be payable in respect of the issue or delivery of any shares of
capital stock and/or other securities on conversion or redemption of shares of
LMG Stock.  TCI will not, however, be required to pay any tax that may be
payable in respect of any transfer involved in the issue and delivery of any
shares of capital stock in a name other than that in which the shares of LMG
Stock so converted or redeemed were registered and no such issue or delivery
will be made unless and until the person requesting such issue has paid to TCI
the amount of any such tax, or has established to the satisfaction of TCI that
such tax has been paid.

     Provisions substantially the same as those described under this caption "--
General Conversion and Redemption Provisions," apply in the event of a
Disposition of all or substantially all of the properties and assets of the TCI
Ventures Group and a determination of TCI to pay a dividend on or undertake a
partial or complete redemption of the TCIVG Stock following such Disposition, in
the event of any conversion of the TCIVG Stock as described under "--Conversion
and Redemption--Conversion of TCIVG Stock at the Option of TCI" or "--Conversion
and Redemption--Mandatory Dividend, Redemption or Conversion of TCIVG Stock,"
and in the event of a redemption of the TCIVG Stock in exchange for stock of one
or more subsidiaries as described under "--Conversion and Redemption--Redemption
of TCIVG Stock in Exchange for Stock of Subsidiary."

     LIQUIDATION RIGHTS

     In the event of a liquidation, dissolution or winding up of TCI, whether
voluntary or involuntary, after payment or provision for payment of the debts
and other liabilities of TCI and subject to the prior payment in full of the
preferential amounts to which any class or series of TCI Preferred Stock is
entitled, (i) the holders of the shares of TCI Group Stock will share equally,
on a share for share basis, in a percentage of the funds of TCI remaining for
distribution to its common stockholders equal to 100% multiplied by the average
daily ratio (expressed as a decimal) of W/Z for the 20-Trading Day period ending
on the Trading Day prior to the date of the public announcement of such
liquidation, dissolution or winding up, (ii) the holders of the shares of LMG
Stock will share equally, on a share for share basis, in a percentage of the
funds of TCI remaining for distribution to its common stockholders equal to 100%
multiplied by the average daily ratio (expressed as a decimal) of X/Z for such
20-Trading Day period and (iii) the holders of the shares of TCIVG Stock will
share equally, on a share for share basis, in a percentage of the funds of TCI
remaining for distribution to its common stockholders equal to 100% multiplied
by the average daily ratio (expressed as a decimal) of Y/Z for such 20-Trading
Day period, where W is the aggregate Market Capitalization of the TCI Group
Series A Stock and the TCI Group Series B Stock, X is the aggregate Market
Capitalization of the LMG Series A Stock and the LMG Series B Stock, Y is the
aggregate Market Capitalization of the TCIVG Series A Stock and the TCIVG Series
B Stock, and Z is the aggregate Market Capitalization of the TCI Group Series A
Stock, the TCI Group Series B Stock, the LMG Series A Stock, the LMG Series B
Stock, the TCIVG Series A Stock and the TCIVG Series B Stock.  Neither a
consolidation, merger nor sale of assets will be construed to be a
"liquidation," "dissolution" or "winding up" of TCI.

     No holder of LMG Stock, TCI Group Stock or TCIVG Stock will have any
special right to receive specific assets of the Liberty Media Group, the TCI
Group or the TCI Ventures Group, as the case may be, in the case of any
dissolution, liquidation or winding up of TCI.

     DETERMINATIONS BY THE TCI BOARD

     The TCI Charter provides that any determinations made by the TCI Board
under any provision described under "DESCRIPTION OF TCI CAPITAL STOCK--Common
Stock" will be final and binding on all stockholders of TCI, except as may
otherwise be required by law.  Such a determination would not be binding if it
were established that the determination was made in breach of a fiduciary duty
of the TCI Board.  TCI will prepare a statement of any such determination by the
TCI Board respecting the fair market value of any properties, assets or
securities and will file such statement with the Secretary of TCI.

     PREEMPTIVE RIGHTS

     Holders of the TCI Group Stock, the LMG Stock and the TCIVG Stock do not
have any preemptive rights to subscribe for any additional shares of capital
stock or other obligations convertible into or exercisable for shares of capital
stock that may hereafter be issued by TCI.

PREFERRED STOCK

     As of June 30, 1998, 1,552,490 shares of Class B Preferred Stock (net of
shares held by subsidiaries of TCI), 44,575 shares of Series C-TCI Group
Preferred Stock, 70,575 shares of Series C-LMG Preferred Stock, 278,307 shares
of Series F Preferred Stock, 6,446,794 shares of Series G Preferred Stock and
6,567,794 shares of Series H Preferred Stock were outstanding.  All of the
outstanding shares of Series F Preferred Stock and 67,536 shares of Class B
Preferred Stock are held by subsidiaries of  TCI.  As of June 30, 1998,
35,061,783 shares of Series Preferred Stock remain available for designation
pursuant to the TCI Charter.  The rights evidenced by the TCI Common Stock are
subject to the prior preferences and rights of the TCI Preferred Stock.

     As of the date of this Proxy Statement/Prospectus, the liquidation
preference of each class and series of TCI Preferred Stock is as follows: (i)
$100 per share for the Class B Preferred Stock, (ii) $2,208.35 per share for the
Series C-TCI Group Preferred Stock, (iii) $579.31 per share for the Series C-LMG
Preferred Stock, (iv) $.01 per share for the Series F Preferred Stock, (v)
$21.60 per share for the Series G Preferred Stock, and (vi) $5.40 per share for
the Series H Preferred Stock.  After receipt of their liquidation preference,
holders of Series F Preferred Stock are entitled to receive from the assets of
TCI available for distribution to common stockholders an amount equal to the
amount per share to be distributed to holders of TCI Group Series A Stock in
such liquidation, multiplied by the number of shares of TCI Group Series A Stock
into which their shares of Series F Preferred Stock are then convertible.

     As of the date of this Proxy Statement/Prospectus, (i) each share of Series
C-TCI Group Preferred Stock is convertible at the option of the holder into
132.86 shares of TCI Group Series A Stock, (ii) each share of Series C-LMG
Preferred Stock is convertible at the option of the holder into 37.5 shares of
LMG Series A Stock (and, as a result of the LMG Stock Dividend, an additional
share of LMG Series A Stock for every two such shares received upon conversion),
(iii) each share of Series F Preferred Stock is convertible into 1,496.65 shares
of TCI Group Series A Stock, (iv) each share of Series G Preferred Stock is
convertible at the option of the holder into 1.190 shares of TCI Group Series A
Stock, and (v) each share of Series H Preferred Stock is convertible at the
option of the holder into .2625 shares of LMG Series A Stock (and, as a result
of the LMG Stock Dividend, an additional share of LMG Series A Stock for every
two such shares received upon conversion), in each case subject to antidilution
adjustments.  The Series C-TCI Group Preferred Stock and the Series C-LMG
Preferred Stock are required to be redeemed by TCI at any time on or after
August 8, 2001, in each case at the option of the holder, in whole or in part
(provided that the aggregate liquidation value of the shares to be redeemed is
in excess of $1 million).  The Series G Preferred Stock and the Series H
Preferred Stock are required to be redeemed by TCI out of legally available
funds on February 1, 2016.

     The Class B Preferred Stock, the Series F Preferred Stock, the Series G
Preferred Stock and the Series H Preferred Stock are each entitled to vote, on
the basis of one vote per share, together with the TCI Common Stock and any
class or series of TCI Preferred Stock entitled to vote thereon, in the general
election of directors of TCI.  The holders of shares of Series C-TCI Group
Preferred Stock and Series C-LMG Preferred Stock are entitled to vote such
shares on an as converted basis on all matters submitted to a vote of holders of
the capital stock of TCI entitled to vote generally on the election of
directors.  Except as described above and as otherwise required by the DGCL or
the TCI

                                       83

Charter, the currently outstanding TCI Preferred Stock has no voting rights. The
terms of the various classes and series of the TCI Preferred Stock include
provisions that restrict the redemption or repurchase of and the payment of
dividends or the making of distributions on the TCI Common Stock if any
dividends are in arrears on the TCI Preferred Stock or if TCI has failed to
redeem any shares of TCI Preferred Stock that it was required to redeem.

ANTI-TAKEOVER CONSIDERATIONS

     The DGCL, the TCI Charter and TCI's Bylaws contain provisions which may
serve to discourage or make more difficult a change in control of TCI without
the support of the TCI Board or without meeting various other conditions. The
principal provisions of the DGCL, the TCI Charter and TCI's Bylaws with respect
to the foregoing are outlined below.

     DGCL Section 203, in general, prohibits a "business combination" between a
corporation and an "interested stockholder" within three years of the time such
stockholder became an "interested stockholder," unless (i) prior to such time
the board of directors of the corporation approved either the business
combination or the transaction which resulted in the stockholder becoming an
interested stockholder, (ii) upon consummation of the transaction which resulted
in the stockholder becoming an interested stockholder, the interested
stockholder owned at least 85% of the voting stock of the corporation
outstanding at the time the transaction commenced, exclusive of shares owned by
directors who are also officers and by certain employee stock plans or (iii) at
or subsequent to such time, the business combination is approved by the board of
directors and authorized by the affirmative vote at a stockholders' meeting of
at least 66% of the outstanding voting stock which is not owned by the
interested stockholder.  The term "business combination" is defined to include,
among other transactions between the interested stockholder and the corporation
or any direct or indirect majority-owned subsidiary thereof, a merger or
consolidation; a sale, pledge, transfer or other disposition (including as part
of a dissolution) of assets having an aggregate market value equal to 10% or
more of either the aggregate market value of all assets of the corporation on a
consolidated basis or the aggregate market value of all the outstanding stock of
the corporation; certain transactions that would increase the interested
stockholder's proportionate share ownership of the stock of any class or series
of the corporation or such subsidiary; and any receipt by the interested
stockholder of the benefit of any loans, advances, guarantees, pledges or other
financial benefits provided by or through the corporation or any such
subsidiary.  In general, and subject to certain exceptions, an "interested
stockholder" is any person who is the owner of 15% or more of the outstanding
voting stock (or, in the case of a corporation with classes of voting stock with
disparate voting power, 15% or more of the voting power of the outstanding
voting stock) of the corporation, and the affiliates and associates of such
person.  The term "owner" is broadly defined to include any person or entity
that individually or with or through such person's or entity's affiliates or
associates, among other things, beneficially owns such stock, or has the right
to acquire such stock (whether such right is exercisable immediately or only
after the passage of time) pursuant to any agreement or understanding or upon
the exercise of warrants or options or otherwise or has the right to vote such
stock pursuant to any agreement or understanding, or has an agreement or
understanding with the beneficial owner of such stock for the purpose of
acquiring, holding, voting or disposing of such stock.  The restrictions of DGCL
Section 203 do not apply to corporations that have elected, in the manner
provided therein, not to be subject to such section or, with certain exceptions,
which do not have a class of voting stock that is listed on a national
securities exchange or authorized for quotation on The Nasdaq Stock Market or
held of record by more than 2,000 stockholders.

     The TCI Charter does not contain any provision "opting out" of the
application of DGCL Section 203 and TCI has not taken any of the actions
necessary for it to "opt out" of such provision.  As a result, the provisions of
Section 203 will remain applicable to transactions between TCI and any of its
"interested stockholders."

     The TCI Charter also contains certain provisions which could make a change
in control of TCI more difficult. For example, the TCI Charter requires, subject
to the rights, if any, of any class or series of TCI Preferred Stock, the
affirmative vote of 66% of the total voting power of the outstanding shares of
TCI Voting Securities (as defined below), voting together as a single class, to
approve (i) a merger or consolidation of TCI with, or into, another corporation,
other than a merger or consolidation which does not require the consent of
stockholders under the DGCL or a merger or consolidation which has been approved
by 75% of the members of the TCI Board (in which case, in accordance with the
DGCL, the affirmative vote of a majority of the total voting power of the
outstanding TCI Voting Securities would, with certain exceptions, be required
for approval), (ii) the sale, lease or exchange of all or substantially

                                       84
<PAGE>
 
all of the property and assets of TCI or (iii) the dissolution of TCI. The term
"TCI Voting Securities" is defined in the TCI Charter as the TCI Group Stock,
the LMG Stock, the TCIVG Stock and any class or series of TCI Preferred Stock
entitled to vote generally with the holders of TCI Common Stock on matters
submitted to stockholders for a vote, which currently would include the Series
C-TCI Group Preferred Stock and the Series C-LMG Preferred Stock. The TCI
Charter also provides for a TCI Board of not less than three members, divided
into three classes of approximately equal size, with each class to be elected
for a three-year term at the annual meeting of stockholders at which such class
of directors' term expires. The exact number of directors, currently nine, is
fixed by the TCI Board. The holders of TCI Voting Securities and of Class B
Preferred Stock, Series G Preferred Stock and Series H Preferred Stock, voting
together as a single class, vote in elections for directors. (The holders of
TCI's Series F Preferred Stock are entitled to vote in the election of
directors; however, the DGCL prohibits the voting of such shares because such
shares are held by subsidiaries of TCI.) Stockholders of TCI do not have
cumulative voting rights.

     The TCI Charter authorizes the issuance of 50,000,000 shares of Series
Preferred Stock, of which 35,061,783 remain available for issuance as of June
30, 1998.  Under the TCI Charter, the TCI Board is authorized, without further
action by the stockholders of TCI, to establish the preferences, limitations and
relative rights of the Series Preferred Stock.  In addition, 1,900,000,000
shares of TCI Group Stock, 825,000,000 shares of LMG Stock and 825,000,000
shares of TCIVG Stock are currently authorized by the TCI Charter, of which
1,215,568,011 shares of TCI Group Stock, 432,014,977 shares of LMG Stock and
402,108,566 shares of TCIVG Stock remain available for issuance as of June 30,
1998 (in each case, without taking into consideration shares reserved for
issuance upon conversion, exchange or exercise of outstanding convertible or
exchangeable securities and options).  The issue and sale of shares of TCI Group
Stock, LMG Stock, TCIVG Stock and/or Series Preferred Stock could occur in
connection with an attempt to acquire control of TCI, and the terms of such
shares of Series Preferred Stock could be designed in part to impede the
acquisition of such control.

     The TCI Charter requires the affirmative vote of 66% of the total voting
power of the outstanding shares of TCI Voting Securities, voting together as a
single class, to approve any amendment, alteration or repeal of any provision of
the TCI Charter or the addition or insertion of other provisions therein.

     The TCI Charter and TCI's Bylaws provide that a special meeting of
stockholders will be held at any time, subject to the rights of the holders of
any class or series of TCI Preferred Stock, upon the call of the Secretary of
TCI upon (i) the written request of the holders of not less than 66% of the
total voting power of the outstanding shares of TCI Voting Securities or (ii) at
the request of not less than 75% of the members of the TCI Board.  Subject to
the rights of any class or series of TCI Preferred Stock, TCI's Bylaws require
that written notice of the intent to make a nomination at a meeting of
stockholders must be received by the Secretary of TCI, at TCI's principal
executive offices, not later than (a) with respect to an election of directors
to be held at an annual meeting of stockholders, 90 days in advance of such
meeting, and (b) with respect to an election of directors to be held at a
special meeting of stockholders, the close of business on the seventh day
following the day on which notice of such meeting is first given to
stockholders.  The notice must contain: (1) the name and address of the
stockholder who intends to make the nomination and of the person or persons to
be nominated; (2) a representation that the stockholder is a holder of record of
TCI's Voting Securities entitled to vote at the meeting and intends to appear in
person or by proxy at the meeting to nominate the person or persons specified in
the notice; (3) a description of all arrangements or understandings between the
stockholder and each nominee and any other person or persons (naming such person
or persons) pursuant to which the nomination or nominations are to be made by
the stockholder; (4) such other information regarding each nominee proposed by
such stockholder as would have been required to be included in a proxy statement
filed pursuant to the proxy rules of the SEC had each proposed nominee been
nominated, or intended to be nominated, by the TCI Board; and (5) the consent of
each nominee to serve as a director of TCI if so elected.  Any action to remove
directors is required to be for "cause" (as defined in the TCI Charter) and be
approved by the holders of 66% of the total voting power of the outstanding
shares entitled to vote in the election of directors (which would include the
Class B Preferred Stock, the Series G Preferred Stock and the Series H Preferred
Stock, in addition to the TCI Voting Securities).

                      COMPARISON OF STOCKHOLDERS' RIGHTS

     Upon consummation of the Merger, holders of outstanding shares of TINTA
Common Stock (except TCI) will become holders of shares of LMG Series A Stock.
The following is a summary of certain significant provisions affecting, and
differences between, the rights of holders of TINTA Common Stock and the rights
of holders of LMG Series A Stock.  Since both TINTA and TCI are organized under
the laws of the State of Delaware, any differences in the rights of holders of
TINTA Common Stock and LMG Series A Stock arise from various provisions of the
TINTA Charter and TINTA's Bylaws and the TCI Charter and TCI's Bylaws.  The
following summary does not purport to be complete and is qualified in its
entirety by reference to the DGCL and the complete text of the TINTA Charter,
TINTA's Bylaws, the TCI Charter and TCI's Bylaws.   The TCI Charter and TCI's
Bylaws have been filed as exhibits to, or are incorporated by reference in, the
Registration Statement of which this Proxy Statement/Prospectus is a part.  See
"AVAILABLE INFORMATION."

DIVIDEND, REDEMPTION AND CONVERSION RIGHTS ON DISPOSITION OF ASSETS

     TINTA.  The TINTA Charter does not contain any provisions comparable to the
dividend, redemption and conversion rights applicable to the LMG Stock and the
TCIVG Stock described below that would apply in the case of the disposition of
all or substantially all of the properties and assets of TINTA.

     TCI. If TCI disposes of all or substantially all of the assets attributed
to the Liberty Media Group (defined as 80% or more on a current market value
basis), other than in certain types of transactions, TCI is required, at its
option either to (i) distribute to holders of LMG Stock an amount in cash and/or
securities or other property equal to their proportionate interest in the
Liberty Media Group Net Proceeds of such disposition, either by special dividend
or by redemption of all or part of the outstanding shares of LMG Stock, or (ii)
convert each outstanding share of LMG Series A Stock and LMG Series B Stock into
a number (or fraction) of fully paid and nonassessable shares of TCI Group
Series A Stock or TCI Group Series B Stock, respectively, equal in each case to
110% of the average daily ratio over the ten-Trading Day period beginning on the
16th Trading Day after consummation of the transaction of the Market Value of
one share of LMG Series A Stock to the Market Value of one share of TCI Group
Series A Stock.  See "DESCRIPTION OF TCI CAPITAL STOCK--Common Stock--Conversion
and Redemption--Mandatory Dividend, Redemption or Conversion of LMG Stock."

     Similarly, if TCI disposes of all or substantially all of the assets
attributed to the TCI Ventures Group (defined as 80% or more on a current market
value basis), other than in certain types of transactions, TCI is required, at
its option either to (i) distribute to holders of TCIVG Stock an amount in cash
and/or securities or other property equal to their proportionate interest in the
TCI Ventures Group Net Proceeds of such disposition, either by special dividend
or by redemption of all or part of the outstanding shares of TCIVG Stock, or
(ii) convert each outstanding share of TCIVG Series A Stock and TCIVG Series B
Stock into a number (or fraction) of fully paid and nonassessable shares of TCI
Group Series A Stock or TCI Group Series B Stock, respectively, equal in each

     No provisions comparable to the foregoing dividend, redemption and
conversion rights applicable to the LMG Stock and the TCIVG Stock will apply in
the case of the disposition of all or substantially all of the properties and
assets attributed to the TCI Group.

REDEMPTION IN EXCHANGE FOR STOCK OF SUBSIDIARY

     TINTA.  The TINTA Charter does not contain any provisions comparable to the

discretion of the TCI Board, redeem (without premium) all outstanding shares of
LMG Stock or TCIVG Stock, as the case may be, in exchange for a proportionate
interest in the outstanding shares of any one or more Qualifying Subsidiaries
that hold all of the assets

                                       87
<PAGE>
 
and liabilities attributed to the Liberty Media Group or the TCI Ventures Group,
as the case may be. See "DESCRIPTION OF TCI CAPITAL STOCK--Common Stock--
Conversion and Redemption--Redemption of LMG Stock in Exchange for Stock of
Subsidiary" and "--Redemption of TCIVG Stock in Exchange for Stock of
Subsidiary."

DIVIDENDS AND SHARE DISTRIBUTION

     TINTA.  Subject to the following sentence, any dividends paid on the TINTA
Series A Stock or the TINTA Series B Stock will be paid only on both series, in
equal amounts per share. If a distribution paid in TINTA Series A Stock, TINTA
Series B Stock, other securities of TINTA or securities of any other entity is
to be made with respect to the TINTA Series A Stock or TINTA Series B Stock,
such share distribution may be paid only as follows: (a) a share distribution
consisting of shares of TINTA Series A Stock (or any securities of TINTA
convertible into, exercisable or exchangeable for, or evidencing the right to
purchase any shares of TINTA Series A Stock) to holders of TINTA Series A Stock
and TINTA Series B Stock, on an equal per share basis; or consisting of shares
of TINTA Series B Stock (or securities of TINTA convertible into, exercisable or
exchangeable for, or evidencing the right to purchase any shares of TINTA Series
B Stock) to holders of TINTA Series A Stock and TINTA Series B Stock, on an
equal per share basis; or consisting of shares of TINTA Series A Stock (or
securities of TINTA convertible into, exercisable or exchangeable for, or
evidencing the right to purchase any shares of TINTA Series A Stock) to holders
of TINTA Series A Stock and, on an equal per share basis, shares of TINTA Series
B Stock (or securities of TINTA convertible into, exercisable or exchangeable
for, or evidencing the right to purchase any shares of TINTA Series B Stock) to
holders of TINTA Series B Stock; and (b) a share distribution consisting of any
class or series of securities of TINTA or any other entity other than TINTA
Series A Stock or TINTA Series B Stock (or other than securities of TINTA
convertible into, exercisable or exchangeable for, or evidencing the right to
purchase any shares of TINTA Series A Stock or TINTA Series B Stock) either on
the basis of a distribution of identical securities, on an equal per share
basis, to holders of TINTA Series A Stock and TINTA Series B Stock or on the
basis of a distribution of one class or series of securities to holders of TINTA
Series A Stock and another class or series of securities to holders of TINTA
Series B Stock, provided that the securities so distributed (and, if applicable,
the securities into which the distributed securities are convertible, or for
which they are exercisable or exchangeable, or which the distributed securities
evidence the right to purchase) do not differ in any respect other than their
relative voting rights and related differences in designation, conversion and
share distribution provisions with holders of shares of TINTA Series B Stock
receiving the class or series having the higher relative voting rights (without
regard to whether such rights differ to a greater or lesser extent than the
corresponding differences in voting rights and related differences in
designation, conversion and share distribution provisions between the TINTA
Series A Stock and the TINTA Series B Stock) provided that if the securities so
distributed constitute capital stock of a subsidiary of TINTA, such rights shall
not differ to a greater extent than the corresponding differences in voting
rights, designation, conversion and share distribution provisions between the
TINTA Series A Stock and the TINTA Series B Stock, and provided in each case
that such distribution is otherwise made on an equal per share basis.

     TCI.    Except in the case of dividends paid as share distributions and in
certain other circumstances, (x) any dividends paid on the LMG Series A Stock or
the LMG Series B Stock will be paid only on both series, in equal amounts per

TINTA Board (in which case, in accordance with the DGCL, the affirmative vote of
a majority of the total voting power of the outstanding TINTA

                                       89
<PAGE>

CHARTER OR BYLAW AMENDMENTS

     TINTA.  Subject to the rights of the holders of any series of TINTA
Preferred Stock, the affirmative vote of the holders of at least 66% of the
total voting power of the outstanding shares of TINTA Voting Securities, voting
together as a single class, is required to approve (a) any amendment, alteration
or repeal of any provision of the TINTA Charter or the addition or insertion of
other provisions therein and (b) the adoption, amendment or repeal of any
provision of TINTA's Bylaws; provided, however, that this voting requirement
shall not apply to, and no vote of the stockholders of TINTA is required to
authorize the adoption, amendment or repeal of any provision of TINTA's Bylaws
by the TINTA Board by action taken by the affirmative vote of not less than 75%
of the members of the TINTA Board then in office.

     TCI.    Subject to the rights of the holders of any class or series of TCI

STOCKHOLDER APPROVAL OF CERTAIN BUSINESS COMBINATIONS

     TINTA.  DGCL Section 203 generally prohibits a Delaware corporation from
engaging in a "business combination" with an "interested stockholder" for three
years following the time that such person becomes an interested stockholder,
subject to certain exceptions contained in DGCL Section 203.  See "DESCRIPTION
OF TCI CAPITAL STOCK--Anti-Takeover Considerations."  The TINTA Charter does not
contain any provision "opting out" of the application of DGCL Section 203;
however, the TINTA Board approved the transaction which resulted in TCI becoming
an interested stockholder of TINTA, thereby making the restrictions of DGCL
Section 203 inapplicable to the Merger.

     TCI.    The TCI Charter does not contain any provision "opting out" of the
application of DGCL Section 203 and TCI has not taken any of the actions
necessary for it to "opt out" of such provision.  As a result, the provisions of
Section 203 will remain applicable to transactions between TCI and any of its
"interested stockholders."  See "DESCRIPTION OF TCI CAPITAL STOCK--Anti-Takeover
Considerations."

LIQUIDATION OR DISSOLUTION

     TINTA.  Under the TINTA Charter, in the event of a liquidation,
dissolution or winding up of TINTA, whether voluntary or involuntary, after
payment or provision for payment of the debts and liabilities of TINTA and
subject to the prior payment in full of the preferential amounts to which any
series of TINTA Preferred Stock is entitled, the holders of TINTA Series A Stock
and the holders of TINTA Series B Stock will share equally, on a share for share
basis, in the assets of TINTA remaining for distribution to its common
stockholders.

be, in the case of any dissolution, liquidation or winding up of TCI.


                          SECURITY OWNERSHIP OF TINTA

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS

     On August 1, 1998, TCI beneficially owned, through TCI Ventures Group,
L.L.C., and had sole voting and investment power over, 86,250,000 shares of
TINTA Series A Stock and all of the 11,700,000 outstanding shares of TINTA
Series B Stock, which represented 85% of the outstanding shares of TINTA Common
Stock, 83% of the outstanding shares of TINTA Series A Stock and 92% of the
combined voting power of the TINTA Common Stock outstanding at that date.  TCI's
executive offices are located at Terrace Tower II, 5619 DTC Parkway, Englewood,
Colorado 80111.  TCI is the only person known to TINTA that beneficially owns 5%
or more of either series of TINTA Common Stock.

SECURITY OWNERSHIP OF MANAGEMENT

     The following table sets forth information with respect to the beneficial
ownership of shares of TINTA Series A Stock.  In addition, the table sets forth
information with respect to the beneficial ownership of shares of the following
securities of TCI: (i) TCI Group Series A Stock, (ii) TCI Group Series B Stock,
(iii) LMG Series A Stock, (iv) LMG Series B Stock, (v) TCIVG Series A Stock;
(vi) TCIVG Series B Stock, (vii) Class B Preferred Stock; (viii) Series C-TCI
Group Preferred Stock; (ix) Series C-LMG Preferred Stock; (x) Series G Preferred
Stock; and (xi) Series H Preferred Stock.  The table indicates securities
beneficially owned by (i) each director of TINTA, (ii) the Chief Executive
Officer and each of the four other most highly compensated executive officers of
TINTA for the fiscal year 1997, and (iii) all directors and executive officers
of TINTA as a group.  The table also indicates the pro forma number and
ownership percentage of shares of LMG Series A Stock that will be owned by such
persons immediately after the Effective Time, assuming an Exchange Ratio of 0.58
of a share of LMG Series A Stock for each share of TINTA Common Stock and
assuming such persons do not acquire or dispose of, any shares of TINTA Common
Stock during the period commencing on August 1, 1998 and ending at the Effective
Time.

     Shares issuable upon exercise of options or conversion of convertible
securities and upon vesting of restricted stock awards are deemed to be
outstanding for the purpose of computing the percentage ownership and overall
voting power of persons beneficially owning such securities, but have not been
deemed to be outstanding for the purpose of computing the percentage ownership
or overall voting power of any other person.  Voting power in the table is
computed with respect to a general election of directors of TCI with the TCI
Group Stock, LMG Stock, TCIVG Stock, Class B Preferred Stock, Series C-TCI Group
Preferred Stock, Series C-LMG Preferred Stock, Series G Preferred Stock and
Series H Preferred Stock, voting together as a single class.  So far as is known
to TINTA, the persons indicated below have sole voting and investment power with
respect to the shares indicated as owned by them, except as otherwise stated in
the notes to the table.  The information in the table (including the footnotes)
is as of August 1, 1998.

(13)  Pursuant to a letter agreement dated June 17, 1988, the late Mr. Bob
      Magness (the founder and former Chairman of TCI) and Kearns- Tribune
      Corporation, a newspaper publishing concern, each granted Dr. Malone
      certain rights with respect to the then Class B Common Stock of TCI owned
      by them. Dr. Malone agreed with TCI to forego the exercise of such rights
      in connection with a June 16, 1997 transaction whereby the Estate of Bob
      Magness sold 30,545,864 shares of TCI Group Series B Stock to TCI in
      exchange for an equal number of shares of TCI Group Series A Stock. In
      consideration thereof, TCI granted Dr. Malone the right (the "Malone
      Right") to acquire, at any time and from time to time prior to June 30,
      1999, up to 30,545,864 shares of TCI Group Series B Stock for either (or
      any combination of): (i) shares of TCI Group Series A Stock on a
      one-for-one basis; or (ii) cash based on the closing market price of the
      TCI Group Series B Stock on the NASDAQ/NM for a specified period prior to
      the acquisition of such shares by Dr. Malone (the "TCI-Estates
      Agreement"). Effective February 9, 1998, however, the number of shares of
      TCI Group Series B Stock subject to the Malone Right was reduced from
      30,545,864 to 14,511,570 shares. Dr. Malone and certain members of the
      Magness family, individually, and in certain cases, on behalf of the
      Estate of Betsy Magness and the Estate of Bob Magness (collectively, the
      "Magness Group") have the right to participate with Dr. Malone in any
      acquisition of up to 12,406,238 of the 14,511,570 shares of TCI Group
      Series B Stock subject to the Malone Right on a basis proportionate to the
      relative ownership by the Magness Group and Dr. Malone and his spouse of
      capital stock of TCI having more than one vote per share in the election
      of directors. The Malone Right may be exercised at any time prior to June
      30, 1999. If the Magness Group or any member thereof declines to
      participate in the Malone Right, Dr. Malone may acquire all such shares.
      As of June 24, 1998, Dr. Malone delivered to TCI a notice of his intent to
      exercise the Malone Right in full. The representative of the Magness Group
      delivered a notice to Dr. Malone and TCI of the Magness Group's intent to
      exercise its proportionate share of such right in full. As of August 1,
      1998, the closing of these exercises and the attendant issuance of the
      stock had not occurred. In connection with the foregoing changes to the
      TCI-Estates Agreement, on February 9, 1998, Dr. Malone and Leslie Malone,
      his spouse (collectively, the "Malone Group"), and the Magness Group
      entered into a Stockholders' Agreement, pursuant to which the parties
      agreed to consult with each other on any matter coming to a vote of TCI
      stockholders; provided, however, that in the event of a disagreement, the
      shares of TCI Group Series B Stock, LMG Series B Stock and TCIVG Series B
      Stock held by the Malone Group and the Magness Group would be voted in the
      manner directed by Dr. Malone pursuant to an irrevocable proxy given by
      the Magness Group. As a result of the February 1998 transactions, Dr.
      Malone's beneficial ownership of TCI Common Stock includes the following
      shares held by the Magness Group: 16,365,681 shares of TCI Group Series B
      Stock, 14,292,719 shares of LMG Series B Stock, and 18,684,034 shares of
      TCIVG Series B Stock. In addition, all of the shares subject to the Malone
      Right have been included in Dr. Malone's beneficial stock ownership
      information.

the Company not owned by it;

          WHEREAS, the Boards of Directors of TCI, Merger Sub and the Company
each have determined that it is advisable and in the best interests of their
respective stockholders for TCI to so acquire such shares and, to that end, for
Merger Sub to merge with and into the Company (the "Merger") upon the terms and
subject to the conditions of this Agreement;

          WHEREAS, for United States federal income tax purposes, it is intended
that the Merger shall qualify as a tax-free reorganization within the meaning of

          WHEREAS, TCI has entered into an Agreement and Plan of Restructuring
and Merger, dated as of June 23, 1998, with AT&T Corp. ("AT&T") and Italy Merger

          WHEREAS, neither this Agreement nor the consummation of the
transactions contemplated hereby is contingent on consummation of the
transactions contemplated by the AT&T Agreement.

covenants, representations, warranties and agreements contained herein, the
parties hereto agree as follows:

corporate existence of Merger Sub shall cease and the Company shall continue as

     2.3  Conversion of Securities.
          ------------------------ 

          (a)  Conversion of Company Securities.  At the Effective Time, by
               --------------------------------                            
virtue of the Merger and without any action on the part of TCI, Merger Sub, the
Company or the holders of shares of Company Common Stock:

          (i)  Each share of Company Common Stock issued and outstanding
immediately prior to the Effective Time (other than any shares of Company Common
Stock to be canceled pursuant to Section 2.3(a)(ii)) shall be converted into and
represent the right to receive, and shall be exchangeable for, .58 (the
"Exchange Ratio") of a validly issued, fully paid and nonassessable share of LMG
Series A Stock; provided, however, that if the product of .58 and the LMG Market
                --------  -------                                               
Price on the Closing Date shall be less than $22.00 and TCI shall not
theretofore have terminated this Agreement in accordance with Section
8.1(iii)(A), then the Exchange Ratio shall be increased to equal the quotient
(rounded upwards, if necessary, to the nearest one one-thousandth) obtained by
dividing $22.00 by such LMG Market Price. At the Effective Time, all such shares
of Company Common Stock shall no longer be outstanding and shall automatically
be canceled and retired and shall 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 LMG Series A Stock to
be issued pursuant to this Section 2.3(a)(i) (and any dividends or other
distributions and any cash in lieu of a fractional share payable pursuant to
Sections 2.4(f) and 2.4(g)) with respect thereto upon the surrender of such
certificate in accordance with Section 2.4, without interest.

          (ii) Each share of Company Stock that immediately prior to the
Effective Time is (i) owned of record by TCI or any subsidiary of TCI or (ii)
held in the treasury of the Company or held by any Wholly-Owned Subsidiary of
the Company shall automatically be canceled, retired and cease to exist without
payment of any consideration thereof and without any conversion thereof into LMG
Series A Stock.

          (b)  Conversion of Merger Sub Stock.  At the Effective Time, by virtue
               ------------------------------                                   
of the Merger and without any action on the part of TCI, Merger Sub or the
Company, each share of capital stock of Merger Sub outstanding immediately prior
to the Effective Time shall be converted into and become one share of common
stock of the Surviving Corporation and shall constitute the only outstanding
shares of capital stock of the Surviving Corporation.

     2.4  Exchange of Shares.
          ------------------ 

          (a)  Appointment of Exchange Agent.  On or before the Closing Date, 
               ----------------------------- 
TCI shall enter into an agreement (the "Exchange Agent Agreement") with an
exchange agent selected by TCI and reasonably acceptable to the Company (the
"Exchange Agent"), authorizing such Exchange Agent to act as Exchange Agent
hereunder.

          (b)  Letter of Transmittal.  As soon as reasonably practicable after
               ---------------------                                          
the Effective Time, TCI will instruct the Exchange Agent to mail to each holder
of record of a certificate or certificates which immediately prior to the
Effective Time evidenced issued and outstanding shares of Company Common Stock
(other than shares to be canceled pursuant to Section 2.3(a)(ii)) (the
"Certificates"):  (i) a notice of the effectiveness of the Merger and (ii) a
letter of transmittal (which shall state that delivery shall be effected, and
risk of loss and title to the Certificates shall pass, only upon proper delivery
of the Certificates to the Exchange Agent) with instructions for use in
effecting the surrender and exchange of the Certificates.  Such notice, letter
of transmittal and instructions shall contain such provisions and be in such
form as TCI and the Company may jointly specify.

          (c)  Exchange Procedure.  Promptly following the surrender, in
               ------------------                                       
accordance with such instructions, of a Certificate to the Exchange Agent (or
such other agent or agents as may be appointed by the Exchange Agent or TCI
pursuant to the Exchange Agent Agreement), together with such letter of
transmittal (duly executed) and any other documents required by such
instructions or letter of transmittal, TCI shall, subject to Section 2.4(d),
cause to be distributed to the Person in whose name such Certificate shall have
been issued (i) a certificate registered in the name of such Person representing
the number of whole shares of LMG Series A Stock into which the shares
previously represented by the surrendered Certificate shall have been converted
at the Effective Time pursuant to this Article II and (ii) payment (which shall
be made by check) of any cash payable in lieu of a fractional share of LMG
Series A Stock pursuant to Section 2.4(f). Each Certificate so surrendered shall
forthwith be canceled.

          (d)  Unregistered Transfers of Company Common Stock. In the event of a
               ----------------------------------------------                
transfer of ownership of shares of Company Common Stock which is not registered
in the transfer records of the Company, a certificate representing the proper
number of whole shares of LMG Series A Stock may be issued (and cash in lieu of
a fractional share of LMG Series A Stock may be paid) to the transferee of such
shares if the Certificate evidencing such shares of Company Common Stock
surrendered to the Exchange Agent in accordance with Section 2.4(c) is properly
endorsed for transfer or is accompanied by appropriate and properly endorsed
stock powers and is otherwise in proper form to effect such transfer, if the
Person requesting such transfer pays to the Exchange Agent any transfer or other
taxes payable by reason of such transfer or establishes to the satisfaction of
the Exchange Agent that such taxes have been paid or are not required to be paid
and if such Person establishes to the satisfaction of TCI that such transfer
would not violate applicable federal or state securities laws.

          (e)  Lost, Stolen or Destroyed Certificates.  In the event any
               --------------------------------------                   
Certificate shall have been lost, stolen or destroyed, upon the making of an
affidavit of that fact by the Person claiming such Certificate to be lost,
stolen or destroyed satisfactory to TCI and complying with any other reasonable
requirements imposed by TCI, TCI will cause to be delivered to such Person in
respect of such lost, stolen or destroyed Certificate the shares of LMG Series A
Stock or other property deliverable in respect thereof as determined in
accordance with this Article II.  TCI may, in its discretion, require the owner
of such lost, stolen or destroyed Certificate to give TCI a bond in such sum as
it may direct as indemnity against any claim that may be made against TCI or the
Surviving Corporation with respect to the Certificate alleged to have been lost,
stolen or destroyed.

          (f)  No Fractional Shares.  No certificates or scrip representing
               --------------------                                        
fractional shares of LMG Series A Stock shall be issued upon the surrender for
exchange of Certificates for Company Common Stock; no stock split or dividend
with respect to shares of LMG Series A Stock shall relate to any fractional
share interest, and no such fractional share interest will entitle the owner
thereof to vote as, or to any other rights of, a stockholder of TCI. In lieu of
such fractional shares, any holder of Company Common Stock who would otherwise
be entitled to a fractional share of LMG Series A Stock will, upon surrender of
his Certificate to the Exchange Agent in accordance with Section 2.4(c), be
entitled to receive cash in an amount determined by multiplying such fraction by
the current market value of a whole share of LMG Series A Stock and rounding the
product to the nearest whole cent. The "current market value" of a share of LMG
Series A Stock means, for this purpose, the average of the last reported sale
prices (or, if on any day no sale price is reported, the average of the quoted
high and low bid prices on such day) of a share of LMG Series A Stock on the NNM
(or, if the LMG Series A Stock is not traded on the NNM, on the principal stock
exchange on which such stock is traded) for the period of five consecutive
trading days ending on and including the last full trading day preceding the
Closing Date. No interest shall accrue or be paid with respect to fractional
share interests or with respect to cash payable in lieu of fractional share
interests.

          (g)  No Dividends Before Surrender of Certificates.  No dividends or
               ---------------------------------------------                  
other distributions declared or made after the Effective Time with respect to
LMG Series A 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 LMG
Series A Stock represented thereby, until the holder of record of such
Certificate shall surrender such Certificate as provided herein.  Subject to the
effect of applicable laws, following surrender of any such Certificate, there
shall be paid to the record holder of the certificates representing whole shares
of LMG Series A Stock issued in exchange therefor, without interest, (i) at the
time of such surrender, the amount of dividends or other distributions, if any,
with a record date after the Effective Time theretofore paid by TCI with respect
to such whole shares of LMG Series A Stock, and (ii) at the appropriate payment
date, the amount of dividends or other distributions, if any, with a record date
after the Effective Time but prior to surrender and with a payment date
subsequent to surrender payable with respect to such whole shares of LMG Series
A Stock.

          (h)  No Further Ownership Rights in Company Common Stock.  All shares
               ---------------------------------------------------             
of LMG Series A Stock issued and all cash in lieu of fractional shares paid upon
the surrender for exchange of shares of Company Common Stock in accordance with
the terms hereof shall be deemed to have been issued and paid in full
satisfaction of all rights pertaining to such shares of Company Common Stock,
and there shall be no further registration of transfers on the stock transfer
books of the Surviving Corporation of the shares of Company Common Stock which
were outstanding 

                                      I-9
<PAGE>
 
immediately prior to the Effective Time. Subject to Section 2.4(i), if, after
the Effective Time, Certificates are presented to the Surviving Corporation for
any reason, they shall be canceled and exchanged as provided in this Article II.

          (i) Abandoned Property Laws.  Payment or delivery of the shares of LMG
              -----------------------                                           
Series A Stock, any cash in lieu of fractional shares thereof and any dividends
or distributions with respect thereto in accordance with the terms hereof shall
be subject to applicable abandoned property, escheat and similar laws and none
of TCI, Merger Sub, the Surviving Corporation or the Company shall be liable to
any holder of shares of Company Common Stock or LMG Series A Stock for any such
shares, for any dividends or distributions with respect thereto or for any cash
in lieu of fractional shares which may be delivered to any public official
pursuant to any abandoned property, escheat or similar law.

     2.5  Changes in LMG Series A Stock.  If, after the date hereof and prior to
          -----------------------------                                         
the Effective Time, the LMG Series A Stock shall be recapitalized or
reclassified or TCI shall effect any stock dividend, stock split, or reverse
stock split of LMG Series A Stock or otherwise effect any transaction that
changes the LMG Series A Stock into any other securities (including securities
of another corporation, including, without limitation, securities of AT&T) or
any other dividend or distribution shall be made on the LMG Series A Stock (or
such other securities), then the shares of LMG Series A Stock to be delivered
under this Agreement to the holders of Company Common Stock shall be
appropriately and equitably adjusted to the kind and amount of shares of stock
and other securities and property which the holders of such shares of LMG Series
A Stock would have been entitled to receive had such shares been issued and
outstanding as of the record date for determining stockholders entitled to
participate in such corporate event.

     2.6  Stock Options, SARs and Benefit Plans.
          ------------------------------------- 

          (a) Stock Options.  Each of the then outstanding stock options, if
              -------------                                                 
any, to purchase shares of Company Common Stock (each, a "Company Option")
issued by the Company pursuant to any Company Plan, and any non-plan options to
acquire shares of Company Common Stock set forth in Schedule 2.6 issued by the
Company pursuant to an option agreement or otherwise issued by the Company,
shall, by virtue of the Merger, and without any further action on the part of
any holder thereof, be assumed by TCI and converted into an option (an "Assumed
Option") to purchase that number of shares of LMG Series A Stock determined by
multiplying the number of shares of Company Common Stock subject to such Company
Option at the Effective Time by the Exchange Ratio, at an exercise price per
share of LMG Series A Stock equal to the exercise price per share of such
Company Option immediately prior to the Effective Time divided by the Exchange
Ratio, rounded down to the nearest whole cent.  If the foregoing calculation
results in an Assumed Option being exercisable for a fraction of a share of LMG
Series A Stock, then the number of shares of LMG Series A Stock subject to such
option shall be rounded up to the nearest whole number of shares, with no cash
being payable for such fractional share.  The terms and conditions of each
Assumed Option shall otherwise remain as set forth in the Company Option
converted into such Assumed Option.  The adjustment provided for in this Section
2.6(a) with respect to any options that are "incentive stock options" (as
defined in Section 422 of the Code) shall be and is intended to be effected in a
manner which is consistent with Section 424(a) of the Code.

          (b) Stock Appreciation Rights.  Each of the then outstanding stock
              -------------------------                                     
appreciation rights, if any, with respect to shares of Company Common Stock
(each, a "Company SAR") issued by the Company pursuant to any Company Plan, and
any non-plan stock appreciation rights with respect to shares of Company Common
Stock set forth in Schedule 2.6 issued by the Company pursuant to an option
agreement or otherwise issued by the Company, shall, by virtue of the Merger,
and without any further action on the part of any holder thereof, be assumed by
TCI and converted into a stock appreciation right (an "Assumed SAR") with
respect to that number of shares of LMG Series A Stock equal to the number of
shares of Company Common Stock that were subject to such Company SAR at the
Effective Time multiplied by the Exchange Ratio, at an exercise price per stock
appreciation right equal to (i) in the case of a Company SAR issued in tandem
with Company Options, the exercise price per share of the related Company Option
assumed by TCI as determined above and (ii) in the case of a free standing
Company SAR, the amount determined by dividing the base price per share of such
Company SAR immediately prior to the Effective Time by the Exchange Ratio,
rounded down to the nearest whole cent.  If the foregoing calculation results in
an Assumed SAR being exercisable with respect to a fraction of a share of LMG
Series A Stock, then the number of shares of LMG Series A Stock in respect of
such stock appreciation right shall be rounded up to the nearest whole number of
shares, with no cash being payable for such 

                                      I-10
<PAGE>
 
fractional share. The terms and conditions of each Assumed SAR shall otherwise
remain as set forth in the Company SAR converted into such Assumed SAR.

          (c) Restricted Stock.  Each restricted share of Company Common Stock
              ----------------                                                
granted pursuant to any Company Plan and each restricted share of Company Common
Stock issued pursuant to individual awards not granted pursuant to any Company
Plan shall, by virtue of the Merger, and without any further action on the part
of any holder thereof, be converted into a number of restricted shares of LMG
Series A Stock at the Exchange Ratio determined pursuant to Section 2.3(a)(i)
hereof, and will remain subject to the same restrictions applicable to such
restricted share of Company Common Stock immediately prior to the Effective
Time.

     3.1  Stockholder Meeting.  Except as otherwise required by the fiduciary
          -------------------                                                
duties of the Company Board, as determined in good faith by the Company Board
following the receipt of advice of the Company's outside legal counsel thereon,
(A) the Company, acting through the Company Board, shall, in accordance with
applicable law, the Company Charter and the Company's Bylaws, duly call, give
notice of, convene and hold, as soon as reasonably practicable after the date
hereof, a meeting of the Company's stockholders (the "Special Meeting") for the
purpose of considering and voting upon this Agreement and (B) the Company will,
through the Company Board, recommend to its stockholders the adoption of this
Agreement.

     3.2  Registration Statement and Other SEC Filings.
          -------------------------------------------- 

          (a) Registration Statement and Proxy Statement.  As soon as reasonably
              ------------------------------------------                        
practicable after the execution of this Agreement, the Company shall prepare and
file with the SEC a preliminary proxy statement in form and substance reasonably
satisfactory to TCI, and TCI shall prepare and file with the SEC a Registration
Statement on Form S-4 (the "Registration Statement") in connection with the
registration under the Securities Act of the LMG Series A Stock issuable in the
Merger and upon exercise of the Assumed Options.  The proxy statement furnished
to the Company's stockholders in connection with the Special Meeting (the "Proxy
Statement") shall be included as part of the prospectus forming part of the
Registration Statement.  Each party hereto agrees to use its reasonable best
efforts to cooperate with each other party in connection with the preparation
and filing of the preliminary proxy statement, the Proxy Statement and the
Registration Statement, including providing information to the other party with
respect to itself as may be reasonably required in connection therewith.  Each
of TCI and the Company shall use its reasonable best efforts to respond to any
comments of the SEC, to cause the Registration Statement to be declared
effective under the Securities Act as soon as reasonably practicable after such
filing and to continue to be effective as of the Effective Time and to cause the
Proxy Statement approved by the SEC to be mailed to the Company's stockholders
at the earliest practicable time.  TCI also shall use its reasonable best
efforts to take any reasonable action (other than qualifying to do business in
any jurisdiction in which it is not now so qualified, subjecting itself to
taxation in any jurisdiction in which it is not now so subject, giving any
consent to general service of process in any jurisdiction in which it is not now
subject to such service or changing in any respect its authorized or outstanding
capital stock or the composition of its assets) required to be taken under any
applicable state securities or blue sky laws in connection with the issuance of
the LMG Series A Stock to be covered by the Registration Statement.

          (b) SEC Comments; Amendments and Supplements.  Each of TCI and the
              ----------------------------------------                      
Company shall notify the other party promptly of the receipt of any comments of
the SEC or its staff and of any request by the SEC or its staff or any other
governmental officials for amendments or supplements to the preliminary proxy
statement, the Proxy Statement, the Registration Statement or any other filing
or for additional information, and will supply the other with copies of all
correspondence between it and any of its representatives, on the one hand, and
the SEC or its staff or any other governmental officials, on the other hand,
with respect to the preliminary proxy statement, the Proxy Statement, the
Registration Statement, the Merger or any other filing relating thereto.  The
Proxy Statement, the Registration Statement and such other filings shall comply
in all  material respects with all applicable requirements of law.  If at any

                                      I-11
<PAGE>
 
time prior to the Effective Time, any event shall occur relating to TCI or the
Company, as the case may be, or its subsidiaries or any of their respective
officers, directors, partners or affiliates which should be described in an
amendment or supplement to the Proxy Statement,  the Registration Statement or
any other filing, TCI or the Company, as the case may be, shall inform the other
party promptly after becoming aware of such event and cooperate in filing with
the SEC or its staff or any other government officials, and/or mailing to
stockholders of the Company, such amendment or supplement.

     3.3  Identification of Affiliates.  Promptly after the Special Meeting and
          ----------------------------                                         
before the Closing Date, the Company shall deliver to TCI a letter identifying
all Persons who, to the Company's knowledge, at the time of the Special Meeting
or at the Effective Time, may be deemed to be "affiliates" of the Company for
purposes of Rule 145 under the Securities Act.  The Company shall use its
reasonable best efforts to cause each Person who is identified as an "affiliate"
in the letter referred to above to deliver to TCI, on or prior to the Closing
Date, a written agreement, in substantially the form annexed hereto as Exhibit
3.3, that such Person will not offer to sell or otherwise dispose of any shares
of LMG Series A Stock issued to such Person pursuant to the Merger in violation
of the Securities Act and the rules and regulations thereunder.

     3.4  Reasonable Efforts.  Subject to the terms and conditions of this
          ------------------                                              
Agreement and applicable law and, in the case of the Company, except as
otherwise required by the fiduciary duties of the Company Board (as determined
in good faith by the Company Board following the receipt of advice of the
Company's outside legal counsel thereon), each of the parties hereto shall use
its reasonable best efforts to take, or cause to be taken, all actions, and to
do, or cause to be done, all things reasonably necessary, proper or advisable
under applicable laws and regulations or otherwise to consummate and make
effective the Merger and the other transactions contemplated by this Agreement
as soon as reasonably practicable, including such actions or things as any other
party hereto may reasonably request in order to cause any of the conditions to
such other party's obligation to consummate such transactions specified in
Article VII to be fully satisfied.  Without limiting the generality of the
foregoing, the parties shall (and shall cause their respective directors,
officers and subsidiaries, and use their reasonable best efforts to cause their
respective affiliates, employees, agents, attorneys, accountants and
representatives, to) consult and fully cooperate with and provide reasonable
assistance to each other in (i) obtaining all necessary consents, approvals,
waivers, licenses, permits, authorizations, registrations, qualifications, or
other permission or action by, and giving all necessary notices to and making
all necessary filings with and applications and submissions to, any Governmental
Entity or other Person; (ii) lifting any permanent or preliminary injunction or
restraining order or other similar order issued or entered by any court or
Governmental Entity (an "Injunction") of any type referred to in Section 7.1(c);

reasonably be required under applicable state securities or blue sky laws in
connection with the issuance of the LMG Series A Stock to be covered by the
Registration Statement; (iv) obtaining the tax opinions referred to in Sections
7.2(d) and 7.3(d); and (v) in general, consummating and making effective the
transactions contemplated hereby; provided, however, that in order to obtain any
                                  --------  -------                             
consent, approval, waiver, license, permit, authorization, registration,
qualification, or other permission or action or the lifting of any Injunction
referred to in clause (i) or (ii) of this sentence, no party shall be required
to pay any consideration, to divest itself of any of, or otherwise rearrange the
composition of, its assets or to agree to any conditions or requirements which,
individually or in the aggregate, would have a Material Adverse Effect on the
Company or TCI.  Prior to making any application to or filing with any
Governmental Entity or other Person in connection with this Agreement, each
party shall provide the other party with drafts thereof and afford the other
party a reasonable opportunity to comment on such drafts.

     3.5  Company SIP.  The Company may amend and/or take action with respect to
          -----------                                                           
the Tele-Communications International, Inc. 1995 Stock Incentive Plan (the
"Company SIP") prior to the Effective Time to provide that, upon a termination
of employment by participants of the Company SIP who are employed by the Company
or any of its subsidiaries at the Effective Time with good reason or by the
Company without cause following the Effective Time, options, stock appreciation
rights or other awards granted under the Company SIP in 1997 and outstanding as
of the Effective Time shall be fully vested, and in the case of stock options or
stock appreciation rights be immediately exercisable, and will remain
outstanding for their full original term as if the individual had remained
employed by the Company.

     3.6  Employee Matters. From and after the Effective Time, TCI will cause
          ----------------
the Surviving Corporation to honor, in accordance with their terms, the
executive, employment and other agreements and arrangements relating to officers
and employees of the Company set forth in Schedule 3.6 (the "Executive
Agreements") and all the Company Plans; provided, however, that nothing herein
                                        --------  -------                     
shall preclude any change in any Executive Agreement or Company Plan effective
on a prospective basis that is permitted pursuant to the terms of the applicable
Executive Agreement or Company Plan. Company performance in respect of any
performance or other programs shall be calculated without taking into account
any expenses or costs directly associated with or arising as a result of the
transactions contemplated by this Agreement or any non-recurring charges that
would not reasonably be expected to have been incurred had the transactions
contemplated by this Agreement not occurred. With respect to employees of the
Company, TCI shall assume the obligations of the Company under the Company Plans
as in effect immediately prior to the Effective Time and will provide employee
benefit plans with aggregate employee benefits to Company employees that are no
less favorable than the aggregate benefits provided to them immediately prior to
the Effective Time; provided that TCI at its sole option may provide employee
                    --------
benefits to Company employees which, in the aggregate, are no less favorable
than those applicable to similarly situated employees of TCI. With respect to
any plans established by TCI, to the extent a Company employee becomes eligible
to participate in any such plans by virtue of the Merger, TCI shall grant to
such Company employee from after the Effective Time, credit for all service with
the Company and its affiliates and predecessors (and any other service credited
by the Company under similar Company Plans) prior to the Effective Time for
eligibility to participate, benefit accrual and vesting purposes, including for
purposes of eligibility and participation under TCI's severance policies and
plans, including the calculation of such employee's "Years of Continuous
Service," to the extent such service was credited under the Company Plans on the
Closing Date, and Company employees shall not be subject to any waiting periods
or limitations on benefits for pre-existing conditions under such TCI plans,
including any group health and disability plans, except to the extent such
employees were subject to such limitations under the Company Plans or were
eligible to participate in such TCI plans prior to the Effective Time. TCI
further agrees to maintain the Company's severance plans as in effect on the
date hereof for a period of two years from the Effective Time, without adverse
amendment, for the benefit of Company employees.


                                  ARTICLE IV

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

      The Company hereby represents and warrants to TCI and Merger Sub as
follows:

     4.1  Organization and Qualification. Each of the Company and its
          ------------------------------                              
subsidiaries (i) is a corporation, partnership, limited liability company or
other business association duly organized, validly existing and in good standing
under the laws of the jurisdiction of its incorporation or organization, (ii)
has all requisite corporate, partnership, limited liability company or other
business association power and authority to own, lease and operate its
properties and to carry on its business as it is now being conducted and (iii)
is duly qualified or licensed and in good standing to do business in each
jurisdiction in which the property owned, leased or operated by it or the nature
of the business conducted by it makes such qualification or license necessary,
except in such jurisdictions where the failure to be so duly qualified or
licensed or in good standing has not had and is not reasonably likely to have,
individually or in the aggregate, a Material Adverse Effect on the Company. Each
entity in which the Company, directly or through one or more of its
subsidiaries, has an investment accounted for by the equity method (the "Company
Equity Affiliates") is a corporation, partnership, limited liability company or
other business association (A) duly organized, validly existing and in good
standing under the laws of the jurisdiction of its incorporation or
organization, (B) has all requisite corporate, partnership, limited liability
company or other business association power and authority to own, lease and
operate its properties and to carry on its business as it is now being conducted
and (C) is duly qualified to do business and is in good standing in each
jurisdiction in which the property owned, leased or operated by it, or the
nature of its activities, makes such qualification necessary, except in each
case where such failure to be so existing and in good standing or to have such
power and authority or to be so qualified to do business and be in good standing
has not had and is not reasonably likely to have, individually or in the
aggregate, a Material Adverse Effect on the Company. The Company has heretofore
furnished or made available to TCI a true and complete copy of the Company
Charter and the Company's Bylaws, each as amended through and in effect on the
date hereof.

                                      I-13

     4.2  Authorization and Validity of Agreement.  The Company has all 
          ---------------------------------------                      
requisite corporate power and authority to enter into this Agreement and,
subject to obtaining the approval of its stockholders specified in Section 4.11,
to perform its obligations hereunder and consummate the transactions
contemplated hereby. The execution, delivery and performance by the Company of
this Agreement and the consummation of the transactions contemplated hereby have
been duly authorized by the Company Board and by all other necessary corporate
action on the part of the Company, subject, in the case of the consummation by
it of the Merger, to such approval of the Company's stockholders. This Agreement
has been duly executed and delivered by the Company and (assuming the due
execution and delivery of this Agreement by the other parties hereto)
constitutes a valid and binding agreement of the Company, enforceable against
the Company in accordance with its terms (except insofar as enforceability may
be limited by applicable bankruptcy, insolvency, reorganization, moratorium or
similar laws affecting creditors' rights generally, or by principles governing
the availability of equitable remedies). The Company and the Company Board have
taken all actions necessary to render the provisions of Section 203 of the DGCL
inapplicable to TCI and, with respect to Merger Sub, to the transactions
contemplated by this Agreement.

     4.3  Capitalization.
          -------------- 

          (a) The authorized capital stock of the Company consists of (i)
312,000,000 shares of Company Common Stock, of which 300,000,000 shares are
designated Company Series A Stock and 12,000,000 shares are designated Company
Series B Stock and (ii) 10,000,000 shares of Company Preferred Stock, issuable
in series.

          (b) As of the close of business on June 30, 1998, (i) 103,640,680
shares of Company Series A Stock and 11,700,000 shares of Company Series B Stock
were issued and outstanding, (ii) 15,394,363 shares of Company Series A Stock
and no shares of Company Series B Stock were reserved for issuance upon
conversion, exchange or exercise of outstanding convertible or exchangeable
securities and options and other stock performance awards, (iii) no shares of
Company Preferred Stock were issued and outstanding and no action had been taken
by the Company Board with respect to the designation of the rights and
preferences of any series of Company Preferred Stock, and (iv) 3,382,200 shares
of Company Series A Stock and no shares of Company Series B Stock or Company
Preferred Stock were held in the treasury of the Company or held by subsidiaries
of the Company.

          (c) All outstanding shares of Company Common Stock are duly
authorized, validly issued, fully paid and nonassessable, and no class of
capital stock of the Company is entitled to preemptive rights.

          (d) Except for the Company Debentures, there are no issued or
outstanding bonds, debentures, notes or other indebtedness of the Company or any
of its subsidiaries which have the right to vote (or which are convertible into
other securities having the right to vote) on any matters on which stockholders
of the Company may vote.

          (e) As of the close of business on June 30, 1998, there were no
options, warrants or other rights to acquire capital stock (or securities
convertible into or exercisable or exchangeable for capital stock) from the
Company, other than (i) Company Options or other rights outstanding as of the
close of business on June 30, 1998 representing in the aggregate the right to
purchase or acquire up to 2,757,000 shares of Company Series A Stock, pursuant
to Company Plans or otherwise, (ii) the right of the holders of Company
Debentures to convert such debentures into shares of Company Series A Stock,
pursuant to the terms thereof, and (iii) the right of the holders of shares of
Company Series B Stock to convert such shares into shares of Company Series A
Stock, pursuant to the Company Charter. Upon consummation of the Merger, none of
such options or convertible securities will be exercisable for or convertible
into any shares of capital stock of the Company, but instead will either be
converted in the Merger or be adjusted to be exercisable for or convertible into
shares of LMG Series A Stock in accordance with the terms of this Agreement and
such securities.

          (f) Since June 30, 1998 until the execution of this Agreement, the
Company has not issued any capital stock or any options, warrants or other
rights to acquire capital stock (or securities convertible into or exercisable
or exchangeable for capital stock).

          --------------------------------                                    
on Form 10-K, Form 10-Q and Form 8-K and proxy statements required under the
Exchange Act to be filed with the SEC since January 1, 1996 (collectively, the

make the statements therein, in light of the circumstances under which they were
made, not misleading (except that no representation or warranty is made with
respect to any information regarding TCI included in the Company SEC Filings
which was furnished by TCI expressly for use therein). When filed with the SEC,
the financial statements (including the related notes) included in the Company
SEC Filings complied as to form in all material respects with the applicable
requirements of the Exchange Act and the applicable rules and regulations
thereunder and were prepared in accordance with GAAP applied on a consistent
basis (except as may be indicated therein or in the schedules thereto), and such
financial statements fairly present, in all material respects, the consolidated
financial position of the Company and its consolidated subsidiaries as of the
respective dates thereof and the consolidated results of their operations and
their consolidated cash flows for the respective periods then ended, subject, in
the case of the unaudited interim financial statements, to normal, recurring
year-end audit adjustments. Except (i) as and to the extent disclosed or
reserved against on the balance sheet of the Company as of June 30, 1998
included in the Company SEC Filings, or (ii) as incurred after the date thereof
in the ordinary course of business consistent with prior practice and not
prohibited by this Agreement, none of the Company, any of the Company's
subsidiaries or, to the knowledge of the Company, any Company Equity Affiliate
has incurred any liability or obligation of any kind that, individually or in
the aggregate, has or would have a Material Adverse Effect on the Company.

Company that is not a corporation or partnership;

          (ii)   require any consent, approval, order or authorization of or
other action by any Governmental Entity (a "Government Consent") or any
registration, qualification, declaration or filing with or notice to any

Affiliates or as may otherwise be required under laws applicable to the conduct

pursuant to state securities and blue sky laws, and (F) such Government Consents
and Government Filings the absence or omission of which will not, either
individually or in the aggregate, have a Material Adverse Effect on the Company
or prevent or materially delay the consummation of the Merger;

          (iii)  assuming adoption of this Agreement at the Special Meeting by
the requisite vote of the Company's stockholders, require, on the part of the
Company, any subsidiary of the Company or, to the knowledge of the Company, any
Company Equity Affiliate, any consent by or approval or authorization of (a
"Contract Consent")

Entity), whether under any License or other Contract or otherwise, except (A) as
set forth on Schedule 4.5 and (B) such Contract Consents and Contract Notices

          (iv)  assuming that the Contract Consents and Contract Notices
described on Schedule 4.5 are obtained and given and that any Government
Consents and Governmental Filings required under any Licenses are obtained or

termination, cancellation, suspension, modification or, subject to Section
4.5(v), acceleration of any obligation or any increase in any payment required

benefit plan or practice, or other agreement, obligation, commitment or
concession of any nature (each, a "Contract")) to which the Company, any
subsidiary of the Company or, to the knowledge of the Company, any Company
Equity Affiliate is a party, by which the Company, any subsidiary of the Company
or, to the knowledge of the Company, any Company Equity Affiliate or any of
their respective assets or properties is bound or affected or pursuant to which
the Company, any subsidiary of the Company or, to the knowledge of the Company,
any Company Equity Affiliate is entitled to any rights or benefits (including

Effect on the Company or prevent or materially delay the consummation of the
Merger;

          (v)   require any approval, consent or authorization from the holders
of the Company Debentures. The Merger will result in a "Change of Control" under
the terms of the Company Debentures, and holders of such debentures will have
the right to tender the same, in whole or in part, to the Company for a purchase
price of 100% of principal amount, plus accrued but unpaid interest, within the
time periods and subject to the requirements of the Indenture for the Company
Debentures; or

          (vi)  assuming adoption of this Agreement at the Special Meeting by
the requisite vote of the Company's stockholders and assuming that the
Government Consents and Governmental Filings specified in clause (ii) of this
Section 4.5 are obtained, made and given, result in a Violation of, under or
pursuant to any law, rule, regulation, order, judgment or decree applicable to

Information that is at least as great as the care it normally takes to preserve
its own information of a similar nature, it shall not be liable for any
disclosure that occurs despite the exercise of that degree of care, and in no
event shall a receiving party be liable for any indirect, punitive, special or
consequential damages unless such disclosure resulted from its willful
misconduct or gross negligence in which event it shall be liable in damages for
the disclosing party's lost profits resulting directly and solely from such
disclosure. In the event this Agreement is terminated, each party shall, if so
requested by the other party, promptly return or destroy all of the Proprietary
Information of such other party, including all copies, reproductions, summaries,
analyses or extracts thereof or based thereon in the possession of the receiving
party or its Representatives; provided, however, that the receiving party shall
                              --------  ------- 
not be required to return or cause to be returned summaries, analyses or
extracts prepared by it or its Representatives, but shall destroy (or cause to
be destroyed) the same upon request of the disclosing party.

          For purposes of this Section 6.2, "Proprietary Information" of a party
means all proprietary or confidential information about such party that is
furnished by it or its Representatives to the other party or the other party's
Representatives, regardless of the manner in which it is furnished.
"Proprietary Information" does not include, however, information which (a) has
been or in the future is published or is now or in the future is otherwise in
the public domain through no fault of the receiving party or its
Representatives, (b) was available to the receiving party or its Representatives
on a non-confidential basis prior to its disclosure by the disclosing party, (c)
becomes available to the receiving party or its Representatives on a non-
confidential basis from a Person other than the disclosing party or its
Representatives who is not otherwise bound by a confidentiality agreement with
the disclosing party or its Representatives, or is not otherwise prohibited from
transmitting the information to the receiving party or its Representatives, or
(d) is independently developed by the receiving party or its Representatives
through Persons who have not had, either directly or indirectly, access to or
knowledge of such information.

contemplated by this Agreement without the consent of the other party (which
consent shall not be unreasonably withheld), except to the extent required by
applicable law or the applicable requirements of the National Association of

consistent with timely compliance with such requirement, consult with the other
party prior to making the required release, announcement or statement).

the Effective Time, TCI shall indemnify, defend and hold harmless the present
and former directors, officers, employees or agents of the Company and any of
its subsidiaries, and any Person who is or was serving at the request of the
Company as a director, officer, employee or agent of another Person
(individually an "Indemnified Party" and, collectively, the "Indemnified
Parties") against (i) all losses, claims, damages, costs, expenses (including
fees and expenses of counsel properly retained by an Indemnified Party under
this Section 6.6) (promptly as statements therefor are received), liabilities or
judgments or amounts that are paid in settlement with the approval of TCI (which
approval shall not be unreasonably withheld) of or in connection with any claim,
action, suit, proceeding or investigation based in whole or in part on or
arising in whole or in part out of the fact that such Person was at any time
prior to the Effective Time a director, officer, employee or agent of the
Company, whether pertaining to any matter existing or occurring at or prior to
the Effective Time and whether asserted or claimed prior to, at or after the
Effective Time ("Indemnified Liabilities") and (ii) all Indemnified Liabilities
based in whole or in part on, or arising in whole or in part out of, or
pertaining to this Agreement or the transactions contemplated hereby (and TCI
shall pay expenses in advance of the final disposition of any such action, suit,
proceeding or investigation to each Indemnified Party (including fees and
expenses of counsel properly retained by an Indemnified Party under this Section
6.6), promptly as statements therefor are received, to the full extent permitted
by law upon receipt of the undertaking contemplated by Section 145(e) of the
DGCL), in each case to the full extent that (x) a corporation is permitted under
Delaware law to indemnify or advance expenses to its own directors, officers,
employees or agents, as the case may be, (y) such Indemnified Party would have
been entitled to be indemnified by the Company, if such Indemnified Party was a
director, officer, employee or agent of the Company, with respect to the
Indemnified Liabilities in question under the Company Charter and the Company's
Bylaws as in effect on January 1, 1998 and under any indemnification agreement
with the Company in a form disclosed to TCI prior to the date hereof and (z)
such indemnification otherwise is permitted by applicable law. In the event any
such claim, action, suit, proceeding or investigation is asserted or commenced
against any Indemnified Party (whether before or after the Effective Time), TCI
will be entitled to participate and, to the extent that it may wish, to assume
the defense thereof, except that if TCI also is a subject of such claim, action,
suit, proceeding or investigation and there is, under applicable standards of
professional conduct, a conflict on any significant issue between the position
of TCI and the position of such Indemnified Party, or if TCI shall fail to
assume responsibility for such defense, such Indemnified Party may, subject to
Section

                                      I-24
<PAGE>
 
6.6(b), retain counsel who will represent such Indemnified Party, and TCI shall
pay all fees and expenses of such counsel promptly as statements therefor are
received; provided that such Indemnified Party shall vigorously defend (or, if
          --------
the defense is assumed by TCI, use his reasonable best efforts to assist in the
vigorous defense of) any such matter; provided, further, that TCI shall not be
                                      --------  -------          
liable for any settlement effected without its written consent, which consent,
however, shall not be unreasonably withheld; and provided, further, that TCI
                                                 --------  -------          
shall not have any obligation hereunder to any Indemnified Party when and if a
court of competent jurisdiction shall ultimately determine, after exhaustion of
all avenues of appeal, that such Indemnified Party is not entitled to
indemnification hereunder.

          (b) Indemnification Procedures.  Any Indemnified Party wishing to
              ---------------------------                                  
claim indemnification or advancement of expenses under Section 6.6(a), upon
learning of any such claim, action, suit, proceeding or investigation, shall
promptly notify TCI thereof (provided that the failure so to notify TCI shall
not relieve TCI from any liability which it may have under this Section 6.6,
except to the extent such failure materially prejudices TCI) and shall deliver
to TCI an undertaking to repay any amounts advanced pursuant thereto when and if
a court of competent jurisdiction shall ultimately determine, after exhaustion
of all avenues of appeal, that such Indemnified Party is not entitled to
indemnification hereunder. In no event may the Indemnified Parties retain more
than one lead law firm and one local counsel to represent them with respect to
any such matter unless there is, under applicable standards of professional
conduct, a conflict on any significant issue between the position of any two or
more Indemnified Parties in which case the Indemnified Parties may (unless the
defense of such matter has been assumed by TCI as provided herein) retain, at
the expense of TCI, such number of additional counsel as are necessary to
eliminate all conflicts of the type referred to above.

          (c) Survival of Existing Indemnification Rights.  TCI and Merger Sub
              -------------------------------------------                     
agree that all rights to indemnification, including provisions relating to
advances of expenses incurred in defense of any action, suit or proceeding,
whether civil, criminal, administrative or investigative (each, a "Claim"),
existing in favor of the Indemnified Parties as provided in the Company Charter
or the Company's Bylaws or pursuant to other agreements, or certificates of
incorporation or bylaws or similar documents of any of the Company's
subsidiaries, as in effect as of the date hereof, shall survive the Merger and
shall continue in full  force and effect for a period of not less than six years
from the Effective Time; provided, however, that all rights to indemnification
                         --------  -------                                    
in respect of any Claim asserted, made or commenced within such period shall
continue until the final disposition of such Claim.

          (d) Survival.  This Section 6.6 shall survive the consummation of the
              --------                                                         
Merger.  The provisions of this Section 6.6 are intended to be for the benefit
of and shall be enforceable by each of the Indemnified Parties and his heirs and
legal representatives, and shall be binding on TCI, Merger Sub and the Surviving
Corporation and their respective successors and assigns.

     6.7  Notification of Certain Matters.  Between the date hereof and the
          -------------------------------                                  
Effective Time, each party will give prompt notice in writing to the other party
of: (i) any information that indicates that any of its representations or
warranties contained herein was not true and correct as of the date hereof or
will not be true and correct at and as of the Effective Time with the same force
and effect as if made at and as of the Effective Time (except for changes
permitted or contemplated by this Agreement), (ii) the occurrence or non-
occurrence of any event which will result, or has a reasonable prospect of
resulting, in the failure of any condition, covenant or agreement contained in
this Agreement to be complied with or satisfied, (iii) any failure of the
Company or TCI (or Merger Sub), as the case may be, to comply with or satisfy
any condition, covenant or agreement to be complied with or satisfied by it
hereunder, (iv) any notice or other communication from any third party alleging
that the consent of such third party is or may be required in connection with
the transactions contemplated by this Agreement or that such transactions
otherwise may violate the rights of or confer remedies upon such third party and
(v) any notice of, or other communication relating to, any litigation referred
to in Section 6.8 or any order or judgment entered or rendered therein;
provided, however, that the delivery of any notice pursuant to this Section 6.7
- --------  -------                                                              
shall not limit or otherwise affect the remedies available hereunder to the
party receiving such notice.

     6.8  Defense of Litigation.  Each of the parties agrees, except, in the
          ---------------------                                             
case of the Company, as otherwise required by the fiduciary duties of the
Company Board (as determined in good faith by the Company Board following the
receipt of advice of the Company's outside legal counsel thereon), to vigorously
defend against all actions, suits or 

                                      I-25
<PAGE>
 
proceedings in which such party is named as a defendant which seek to enjoin,
restrain or prohibit the transactions contemplated hereby or seek damages with
respect to such transactions. No party shall settle any such action, suit or
proceeding or fail to perfect on a timely basis any right to appeal any judgment
rendered or order entered against such party therein without the consent of the
other party (which consent shall not be withheld unreasonably). Each of the
parties further agrees to use its reasonable best efforts to cause each of its
affiliates, directors and officers to vigorously defend any action, suit or
proceeding in which such affiliate, director or officer is named as a defendant
and which seeks any such relief to comply with this Section to the same extent
as if such Person were a party hereto.

     6.9  Actions by TCI and Merger Sub.  In its capacity as a beneficial owner
          -----------------------------

all purposes as a vote in favor of this Agreement duly adopted at a meeting of
the stockholders of Merger Sub held for such purpose, and (ii) TCI shall cause
Merger Sub to take all corporate action necessary on its part to consummate the
Merger and the transactions contemplated hereby.  Merger Sub shall not conduct

     9.4  Assignment; Binding Effect; Benefit.
          ----------------------------------- 

          (a) Neither this Agreement nor any of the rights, benefits or
obligations hereunder may be assigned by any party (whether by operation of law
or otherwise) without the prior written consent of the other party. Subject to
the preceding sentence, this Agreement will be binding upon, inure to the
benefit of and be enforceable by the parties and their respective successors and
assigns. Nothing in this Agreement, expressed or implied, is intended to confer
on, or to make enforceable by, any Person other than the parties or their
respective successors and assigns, any rights, remedies, obligations or
liabilities under or by reason of this Agreement, other than rights conferred
upon Indemnified Parties under Section 6.6 and upon stockholders, directors,
officers, affiliates, agents and representatives of the parties under Section
9.11. Notwithstanding anything to the contrary contained in this Agreement, the
provisions of Section 6.6 of this Agreement may not be amended or altered in any
manner with respect to any Indemnified Party without the written consent of such
Indemnified Party. No assignment of this Agreement shall relieve TCI from its
obligations to any Indemnified Party contained in Section 6.6 of this Agreement.

          (b) Notwithstanding Section 9.4(a), this Agreement and all the rights,

stockholders of the Company, this Agreement may be amended by the parties
hereto, by action taken or authorized by their respective Boards of Directors,
at any time prior to the Effective Time; provided, however, that after adoption
                                         --------  -------                     
of this Agreement by the stockholders of the Company, no amendment may be made
without the further requisite approval of such stockholders if such amendment by
law requires the further approval of such stockholders.  This Agreement may not
be amended except by an instrument in writing signed by the parties hereto.

     9.6  Extension; Waiver.  At any time prior to the Effective Time, either of
          -----------------                                                     
the parties, by action taken or authorized by such party's Board of Directors,
may, to the extent legally allowed, (i) extend the time specified herein for the
performance of any of the obligations of the other party, (ii) waive any
inaccuracies in the representations and warranties of the other party contained
herein or in any document delivered pursuant hereto, (iii) waive compliance by
the other party with any of the agreements or covenants of such other party
contained herein or (iv) waive any condition to such waiving party's obligation
to consummate the transactions contemplated hereby or to any of such waiving
party's other obligations hereunder.  Any such extension or waiver shall be
valid only if set forth in a written instrument signed by the party or parties
to be bound thereby.  Any such extension or waiver by any party shall be binding
on such party but not on the other party entitled to the benefits of the
provision of this Agreement affected unless such other party also has agreed to
such extension or waiver.  No such waiver shall constitute a waiver of, or
estoppel with respect to, any subsequent or other breach or failure to strictly
comply with the provisions of this Agreement.  The failure of any party 

                                      I-31
<PAGE>
 
to exercise any of its rights, powers or remedies hereunder or with respect
hereto or to insist on strict compliance with this Agreement shall not
constitute a waiver by such party of its right to exercise any such or other
rights, powers or remedies or to demand such compliance. Whenever this Agreement
requires or permits consent or approval by any party, such consent or approval
shall be effective if given in writing in a manner consistent with the
requirements for a waiver of compliance as set forth in this Section 9.6.

     9.7  Headings.  The table of contents and headings contained in this
          --------                                                       
Agreement are for reference purposes only and shall not affect in any way the
meaning or interpretation of this Agreement.

     9.8  Counterparts.  This Agreement may be executed in any  number of

counterparts, each of which shall be deemed to be an original, and all of which
together shall be deemed to be one and the same instrument.

     9.9  Applicable Law.  This Agreement and the legal relations between the
          --------------                                                     
parties shall be governed by and construed in accordance with the laws of the
State of Delaware, without regard to the conflict of laws rules thereof.

     9.10 Enforcement of this Agreement.  The parties hereto agree that
          -----------------------------                                
irreparable damage would occur in the event that any of the provisions of this
Agreement were not performed in accordance with their specific terms or were
otherwise breached.  It is accordingly agreed that the parties shall be entitled
to an injunction or injunctions to prevent breaches of this Agreement and to
enforce specifically the terms and provisions hereof, this being in addition to
any other remedy to which they are entitled at law or in equity.

     9.11 Limited Liability.  Notwithstanding any other provision of this
          -----------------                                              
Agreement, no stockholder, director, officer, affiliate, agent or representative
of any party (other than TCI as the sole stockholder of Merger Sub) shall have
any liability in respect of or relating to the covenants, obligations,
representations or warranties of such party hereunder or in respect of any
certificate delivered with respect thereto and, to the fullest extent legally
permissible, each party, for itself and its stockholders, directors, officers
and affiliates, waives and agrees not to seek to assert or enforce any such
liability which any such Person otherwise might have pursuant to applicable law.

     9.12 Severability.  If any term or other provision of this Agreement is
          ------------                                                      
invalid, illegal or incapable of being enforced by any rule of law or public
policy, all other conditions and provisions of this Agreement shall nevertheless
remain in full force and effect so long as the economic or legal substance of
the transactions contemplated hereby is not affected in any manner materially
adverse to any party.  Upon such determination that any term or other provision
is invalid, illegal or incapable of being enforced, the parties hereto shall
negotiate in good faith to modify this Agreement so as to effect the original
intent of the parties as closely as possible to the fullest extent permitted by
applicable law in an acceptable manner to the end that the transactions
contemplated hereby are fulfilled to the extent possible.

                        OPINION OF SALOMON SMITH BARNEY


August 21, 1998

Board of Directors
Tele-Communications International, Inc.
5619 DTC Parkway
Englewood, Colorado 80111-3000

Ladies and Gentlemen:

          You have requested our opinion as investment bankers as to the
fairness, from a financial point of view, to the holders of Series A Common
Stock, $1.00 par value per share (the "Company Common Stock"), of Tele-
Communications International, Inc. (the "Company"), other than Tele-
Communications, Inc. ("TCI") or any subsidiary of TCI (collectively, with TCI,
"TCI Holders"), of the Exchange Ratio (as defined below) in connection with the
proposed merger (the "Proposed Merger") of Liberty Group Acquisition Co.
("Merger Sub"), a wholly owned subsidiary of TCI, with and into the Company,
pursuant to the Agreement and Plan of Merger (the "Agreement") by and among the
Company, Merger Sub and TCI.

          As more specifically set forth in the Agreement, and subject to the
terms and conditions thereof, Merger Sub will merge with and into the Company,
and each issued and outstanding share of Company Common Stock (other than shares
owned by the Company, any wholly owned subsidiary of the Company or any TCI
Holder) will be converted in the Proposed Merger into the right to receive 0.58
of a share (the "Exchange Ratio") of TCI Series A Liberty Media Group Common
Stock, $1.00 par value per share ("TCI/Liberty Stock"); provided, however, that
if the product of 0.58 times the Average Market Price (as defined below) of
TCI/Liberty Stock on the date established for the closing of the Proposed Merger
shall be less than $22.00, the Exchange Ratio shall, unless TCI shall have
terminated the Agreement, be increased to equal the quotient (rounded upwards,
if necessary, to the nearest one one-thousandth) obtained by dividing $22.00 by
such Average Market Price (such adjustment being referred to as the "Minimum
Value Adjustment"). In accordance with the Agreement, "Average Market Price"
means the average of the closing sales prices (or, if on any day no sale price
is reported, the average of the quoted high and low bid prices on such day) of a
share of TCI/Liberty Stock on the Nasdaq National Market on each of the five
consecutive trading days immediately preceding the trading day prior to the date
of such determination.

          In connection with rendering our opinion we have reviewed and
analyzed, among other things, the following:  (i) a draft as of August 21, 1998
of the Agreement;  certain publicly available information concerning the
Company, including the Annual Reports on Form 10-K of the Company for each of
the years in the three-year period ended December 31, 1997 and the Quarterly
Reports on Form 10-Q of the Company for the quarters ended March 31, 1998 and
June 30, 1998, respectively; (ii) certain publicly available information
concerning certain entities in which the Company holds a substantial equity
interest (the "Company Portfolio Companies"); (iii) certain other internal
information, primarily financial in nature, including projections, concerning
the business, assets and operations of the Company and the Company Portfolio
Companies furnished to us by the Company for purposes of our analysis; (iv)
certain publicly available information concerning the trading of, and the
trading market for, the Company Common Stock; (v) certain publicly available
information concerning the Liberty Media Group (as such term is defined in the
Restated Certificate of Incorporation of TCI (the "Certificate")) ("Liberty"),
including separate information concerning Liberty contained in the Annual
Reports on Form 10-K of TCI for each of the years in the three-year period ended
December 31, 1997 and the Quarterly Reports on Form 10-Q of TCI for the quarters
ended March 31, 1998 and June 30, 1998, respectively; (vi) certain publicly
available information concerning certain entities in which Liberty holds a
substantial equity interest (the "Liberty Portfolio Companies"); (vii) certain
other internal information, primarily financial in nature, including
projections, concerning the business, assets and 

                                      II-1
<PAGE>
 
operations of Liberty and the Liberty Portfolio Companies furnished to us by
Liberty for the purposes of our analysis; (viii) the Certificate, including the
terms of the TCI/Liberty Stock set forth therein; and (ix) certain publicly
available information concerning the trading of, and the trading market for,
TCI/Liberty Stock. We also have considered such other information, financial
studies, analyses, investigations and financial, economic and market criteria
that we deemed relevant. We have also met with certain officers and employees of
the Company, TCI and Liberty to discuss the foregoing, as well as other matters
we believe relevant to our inquiry.

          In our review and analysis and in arriving at our opinion, we have
assumed and relied upon the accuracy and completeness of all of the financial
and other information provided us or publicly available and have neither
attempted independently to verify nor assumed responsibility for verifying any
of such information. We have not conducted a physical inspection of any of the
properties or facilities of TCI, the Company, Liberty, any Company Portfolio
Company or any Liberty Portfolio Company, nor have we made or obtained or
assumed any responsibility for making or obtaining any independent evaluations
or appraisals of any of such properties or facilities. With respect to
projections, we have assumed that they have been reasonably prepared on bases
reflecting the best currently available estimates and judgments of the
management of the Company or Liberty, as the case may be, as to the future
financial performance of the Company and the Company Portfolio Companies or
Liberty and the Liberty Portfolio Companies, as the case may be, and we express
no view with respect to such projections or the assumptions on which they were
based. We also have assumed that the definitive Agreement, when executed, will
contain a provision incorporating the Minimum Value Adjustment and will not
contain any other terms or conditions that differ materially from the draft we
have reviewed and that the Proposed Merger will be consummated in a timely
manner and in accordance with the terms of the Agreement, without waiver of any
of the conditions precedent to the Proposed Merger contained in the Agreement.
We understand, and have assumed, that the Proposed Merger will qualify as a tax-
free reorganization for federal income tax purposes. We further understand, and
have assumed, that, following the Merger, for purposes of the TCI/Liberty Stock,
Liberty will be deemed to be the beneficial owner of 15% of the outstanding
capital stock of the Company.

          In conducting our analysis and arriving at our opinion as expressed
herein, we have considered such financial and other factors as we have deemed
appropriate under the circumstances including, among others, the following: (x)
the historical and current financial position and results of operations of the
Company, Liberty, the Company Portfolio Companies and the Liberty Portfolio
Companies; (xi) the business prospects of the Company, Liberty, the Company
Portfolio Companies and the Liberty Portfolio Companies; (xii) the terms of the
TCI/Liberty Stock; and (xiii) the historical and current market for the Company
Common Stock and the TCI/Liberty Stock. We also have taken into account our
assessment of general economic, market and financial conditions as well as our
experience in connection with similar transactions and securities valuation
generally. Our opinion necessarily is based upon conditions as they exist and
can be evaluated on the date hereof and we assume no responsibility to update or
revise our opinion based upon circumstances or events occurring after the date
hereof.

          We have not been asked to consider, and our opinion does not address,
the relative merits of the Proposed Merger as compared to any alternative
business strategy that might exist for the Company. We understand that TCI is a
party to an Agreement and Plan of Restructuring and Merger with AT&T Corp.,
dated as of June 23, 1998, pursuant to which it is contemplated that a wholly
owned subsidiary of AT&T Corp. will merge with and into TCI (the "AT&T Merger")
and holders of TCI/Liberty Stock will receive shares of the Class A Liberty
Group Common Stock of AT&T ("AT&T/Liberty Stock") in exchange for TCI/Liberty
Stock (the "AT&T Exchange"). We have not been asked to consider, and this
opinion does not address, the AT&T Merger or the AT&T Exchange or the effect
thereof on TCI/Liberty Stock or the effect, if any, of any decision not to
proceed with or consummate the AT&T Merger. We further understand that it is
contemplated that TCI Ventures Group (as such term is defined in the
Certificate) will merge with and into Liberty (the "Ventures/Liberty Merger")
following consummation of the Proposed Merger. We have not been asked to
consider for the purposes of this opinion, and this opinion does not address,
the Ventures/Liberty Merger or the effect thereof on TCI/Liberty Stock or the
effect, if any, of any decision not to proceed with or consummate the
Ventures/Liberty Merger. We have taken into account the fact that the TCI
Holders currently own, directly or indirectly, approximately 85% of the
outstanding Company Common Stock. Our opinion as expressed below does not
constitute an opinion or imply any conclusion as to the likely trading range for
TCI/Liberty Stock following consummation of the Proposed Merger or the
Ventures/Liberty Merger or the likely 

                                      II-2
<PAGE>
 
trading range for AT&T/Liberty Stock following consummation of the AT&T Merger.
Our opinion is, in any event, limited to the fairness, from a financial point of
view, of the Exchange Ratio to the holders of Company Common Stock, other than
the TCI Holders, and does not constitute a recommendation to any holder of
Company Common Stock as to how such holder should vote with respect to the
Proposed Merger.

          As you are aware, Salomon Brothers Inc and Smith Barney Inc., doing
business as Salomon Smith Barney (collectively with all other entities doing
business as Salomon Smith Barney, "Salomon Smith Barney"), are acting as
financial advisor to the Company in connection with the Proposed Merger and will
receive a fee for our services. In addition, in the ordinary course of business,
Salomon Smith Barney may actively trade the debt and equity securities of the
Company, TCI (including TCI/Liberty Stock) and AT&T for its own account and for
the accounts of customers and, accordingly, may at any time hold a long or short
position in such securities. Additionally, Salomon Smith Barney or its
affiliates previously have rendered certain investment banking and financial
advisory services to the Company, TCI, Liberty, TCI Ventures Group and AT&T, for
which Salomon Smith Barney received customary compensation.  Salomon Smith
Barney and its affiliates (including Travelers Group Inc.) may have other
business relationships with the Company and TCI.

          This opinion is intended for the benefit and use of the Company
(including its management and directors) in considering the transaction to which
it relates and may not be used by the Company for any other purpose or
reproduced, disseminated, quoted or referred to by the Company at any time, in
any manner or for any purpose, without the prior written consent of Salomon
Smith Barney, except that it may be introduced into evidence and other
references to it may be made in connection with any litigation relating to the
Proposed Merger and it may be reproduced in full in any proxy or information
statement relating to the Proposed Merger that the Company files with the
Securities and Exchange Commission under the Securities Exchange Act of 1934.

          Based upon and subject to the foregoing, we are of the opinion as
investment bankers that the Exchange Ratio is fair, from a financial point of
view, to the holders of Company Common Stock other than the TCI Holders.

                               Very truly yours,



                               SALOMON SMITH BARNEY

                                    PART II
                    INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section 145 of the Delaware General Corporation Law provides, generally,
that a corporation shall have the power to indemnify any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding (except actions by or in the right of the
corporation) by reason of the fact that such person is or was a director,
officer, employee or agent of the corporation against all expenses, judgments,
fines and amounts paid in settlement actually and reasonably incurred by such
person in connection with such action, suit or proceeding if such person acted
in good faith and in a manner such person reasonably believed to be in or not
opposed to the best interests of the corporation and, with respect to any
criminal action or proceeding, had no reasonable cause to believe his or her
conduct was unlawful. A corporation may similarly indemnify such person for
expenses actually and reasonably incurred by such person in connection with the
defense or settlement of any action or suit by or in the right of the
corporation, provided such person acted in good faith and in a manner he or she
reasonably believed to be in or not opposed to the best interests of the
corporation, and, in the case of claims, issues and matters as to which such
person shall have been adjudged liable to the corporation, provided that a court
shall have determined, upon application, that, despite the adjudication of
liability but in view of all of the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such expenses which such court
shall deem proper.

     Section 102(b)(7) of the Delaware General Corporation Law provides,
generally, that the certificate of incorporation may contain a provision
eliminating or limiting the personal liability of a director to the corporation
or its stockholders for monetary damages for breach of fiduciary duty as a
director, provided that such provision may not eliminate or limit the liability
of a director (i) for any breach of the director's duty of loyalty to the
corporation or its stockholders, (ii) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (iii) under
section 174 of Title 8 of the Delaware General Corporation Law, or (iv) for any
transaction from which the director derived an improper personal benefit. No
such provision may eliminate or limit the liability of a director for any act or
omission occurring prior to the date when such provision became effective.

     Article V, Section E of the Restated Certificate of Incorporation, as
amended ("TCI Charter"), of Tele-Communications, Inc., a Delaware corporation
("TCI"), provides as follows:

     "1.  Limitation on Liability.
          ----------------------- 

          To the fullest extent permitted by the Delaware General Corporation
          Law as the same exists or may hereafter be amended, a director of the
          Corporation shall not be liable to the Corporation or any of its
          stockholders for monetary damages for breach of fiduciary duty as a
          director. Any repeal or modification of this paragraph 1 shall be
          prospective only and shall not adversely affect any limitation, right
          or protection of a director of the Corporation existing at the time of
          such repeal or modification.

     2.   Indemnification.
          --------------- 

          (a)  RIGHT TO INDEMNIFICATION.  The Corporation shall indemnify and
          hold harmless, to the fullest extent permitted by applicable law as it
          presently exists or may hereafter be amended, any person who was or is
          made or is threatened to be made a party or is otherwise involved in
          any action, suit or proceeding, whether civil, criminal,
          administrative or investigative (a "proceeding") by reason of the fact
          that he, or a person for whom he is the legal representative, is or
          was a director or officer of the Corporation or is or was serving at
          the request of the Corporation as a director, officer, employee or
          agent of another corporation or of a partnership, joint venture,
          trust, enterprise or nonprofit entity, including service with respect
          to employee benefit plans, against all liability and loss suffered and
          expenses (including attorneys' fees) reasonably incurred by such
          person. Such right of indemnification shall inure whether or not the
          claim asserted is based on matters which antedate the adoption of this
          Section E. The Corporation shall be required to indemnify a person in
          connection with a proceeding

                                     II-1
<PAGE>
 
          (or part thereof) initiated by such person only if the proceeding (or
          part thereof) was authorized by the Board of Directors of the
          Corporation.

          (b)  PREPAYMENT OF EXPENSES.  The Corporation shall pay the expenses
          (including attorneys' fees) incurred in defending any proceeding in
          advance of its final disposition, provided, however, that the payment
          of expenses incurred by a director or officer in advance of the final
          disposition of the proceeding shall be made only upon receipt of an
          undertaking by the director or officer to repay all amounts advanced
          if it should be ultimately determined that the director or officer is
          not entitled to be indemnified under this paragraph or otherwise.

          (c)  CLAIMS.  If a claim for indemnification or payment of expenses
          under this paragraph is not paid in full within 60 days after a
          written claim therefor has been received by the Corporation, the
          claimant may file suit to recover the unpaid amount of such claim and,
          if successful in whole or in part, shall be entitled to be paid the
          expense of prosecuting such claim. In any such action the Corporation
          shall have the burden of proving that the claimant was not entitled to
          the requested indemnification or payment of expenses under applicable
          law.

          (d)  NON-EXCLUSIVITY OF RIGHTS.  The rights conferred on any person by
          this paragraph shall not be exclusive of any other rights which such
          person may have or hereafter acquire under any statute, provision of
          this Certificate, the Bylaws, agreement, vote of stockholders or
          disinterested directors or otherwise.

          (e)  OTHER INDEMNIFICATION.  The Corporation's obligation, if any, to
          indemnify any person who was or is serving at its request as a
          director, officer, employee or agent of another corporation,
          partnership, joint venture, trust, enterprise or nonprofit entity
          shall be reduced by any amount such person may collect as
          indemnification from such other corporation, partnership, joint
          venture, trust, enterprise or nonprofit entity.

     3.   Amendment or Repeal.
          ------------------- 

          Any repeal or modification of the foregoing provisions of this Section
          E shall not adversely affect any right or protection hereunder of any
          person in respect of any act or omission occurring prior to the time
          of such repeal or modification."

     Article II, Section 2.9 of TCI's Bylaws also contains an indemnity
provision, requiring TCI to indemnify members of the Board of Directors and
officers of TCI and their respective heirs, personal representatives and
successors in interest for or on account of any action performed on behalf of
TCI, to the fullest extent provided by the laws of the State of Delaware and the
TCI Charter, as then or thereafter in effect.

     TCI has also entered into indemnification agreements with each of its
directors (each director, an "indemnitee"). The indemnification agreements
provide (i) for the prompt indemnification to the fullest extent permitted by
law against any and all expenses, including attorneys' fees and all other costs,
expenses and obligations paid or incurred in connection with investigating,
defending, being a witness or participating in (including on appeal), or in
preparing for ("Expenses"), any threatened, pending or completed action, suit or
proceeding, or any inquiry or investigation ("Claim"), related to the fact that
such indemnitee is or was a director, officer, employee, agent or fiduciary of
TCI or is or was serving at TCI's request as a director, officer, employee,
trustee, agent or fiduciary of another corporation, partnership, joint venture,
employee benefit plan, trust or other enterprise, or by reason of anything done
or not done by a director or officer in any such capacity, and against any and
all judgments, fines, penalties and amounts paid in settlement (including all
interest, assessments and other charges paid or payable in connection therewith)
of any Claim, unless the Reviewing Party (one or more members of the Board of
Directors or other person appointed by the Board of Directors, who is not a
party to the particular claim, or independent legal counsel) determines that
such indemnification is not permitted under applicable law and (ii) for the
prompt advancement of Expenses, and for reimbursement to TCI if the Reviewing
Party determines that such indemnitee is not entitled to such indemnification
under applicable law. In

                                     II-2
<PAGE>
 
addition, the indemnification agreements provide (i) a mechanism through which
an indemnitee may seek court relief in the event the Reviewing Party determines
that the indemnitee would not be permitted to be indemnified under applicable
law (and therefore is not entitled to indemnification or expense advancement
under the indemnification agreement) and (ii) indemnification against all
expenses (including attorneys' fees), and advancement thereof if requested,
incurred by the indemnitee in seeking to collect an indemnity claim or
advancement of expenses from TCI or incurred in seeking to recover under a
directors' and officers' liability insurance policy, regardless of whether
successful or not. Furthermore, the indemnification agreements provide that
after there has been a "change in control" in TCI (as defined in the
indemnification agreements), other than a change in control approved by a
majority of directors who were directors prior to such change, then, with
respect to all determinations regarding a right to indemnity and the right to
advancement of Expenses, TCI will seek legal advice only from independent legal
counsel selected by the indemnitee and approved by TCI.

     The indemnification agreements impose upon TCI the burden of proving that
an indemnitee is not entitled to indemnification in any particular case and
negate certain presumptions that may otherwise be drawn against an indemnitee
seeking indemnification in connection with the termination of actions in certain
circumstances. Indemnitees' rights under the indemnification agreements are not
exclusive of any other rights they may have under Delaware law, TCI's Bylaws or
otherwise. Although not requiring the maintenance of directors' and officers'
liability insurance, the indemnification agreements require that an indemnitee
be provided with the maximum coverage available for any director or officer of
TCI if there is such a policy.

     TCI may purchase liability insurance policies covering its directors and
officers.

ITEM 22.  UNDERTAKINGS

     (a)  TCI hereby undertakes:

     (1)  To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:

               (i)    To include any prospectus required by section 10(a)(3) of
     the Securities Act of 1933;

               (ii)   To reflect in the prospectus any facts or events arising
     after the effective date of the registration statement (or the most recent
     post-effective amendment thereof) which, individually or in the aggregate,
     represent a fundamental change in the information set forth in the
     registration statement. Notwithstanding the foregoing, any increase or
     decrease in volume of securities offered (if the total dollar value of
     securities offered would not exceed that which was registered) and any
     deviation from the low or high end of the estimated maximum offering range
     may be reflected in the form of the prospectus filed with the Commission
     pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
     price represent no more than a 20% change in the maximum aggregate offering
     price set forth in the "Calculation of Registration Fee" table in the
     effective registration statement; and

               (iii)  To include any material information with respect to the
     plan of distribution not previously disclosed in the registration statement
     or any material change to such information in the registration statement;

     (2)  That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

     (3)  To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.

     (4)  That, for purposes of determining any liability under the Securities
Act of 1933, each filing of the Registrant's annual report pursuant to Section
13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where
applicable, each filing of an employee benefit plan's annual report pursuant to
Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by
reference in the registration statement shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.

     (5)  That prior to any public reoffering of the securities registered
hereunder through use of a prospectus which is part of this registration
statement, by any person or party who is deemed to be an underwriter within the
meaning of Rule 145(c), TCI undertakes that such reoffering prospectus will
contain the information called for by the applicable registration form with
respect to reofferings by persons who may be deemed underwriters, in addition to
the information called for by the other Items of the applicable form.

     (6)  That every prospectus (i) that is filed pursuant to the paragraph
immediately preceding, or (ii) that purports to meet the requirements of Section
10(a)(3) of the Securities Act of 1933 and is used in connection with an
offering of securities subject to Rule 415, will be filed as a part of an
amendment to the registration statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

     (7)  To respond to requests for information that is incorporated by
reference into the prospectus pursuant to Item 4, 10(b), 11, or 13 of this Form
within one business day of receipt of such request, and to send the incorporated
documents by first class mail or other equally prompt means. This includes
information contained in documents filed subsequent to the effective date of the
registration statement through the date of responding to the request.

                                     II-5
<PAGE>
 
     (8)  To supply by means of a post-effective amendment all information
concerning a transaction, and the company being acquired involved therein, that
was not the subject of and included in the registration statement when it became
effective, provided, in the case of a transaction that (but for the possibility
of integration with other transactions) would itself qualify for an exemption
from registration, that (i) such transaction by itself or when aggregated with
other such transactions made since the filing of the most recent audited
financial statements of TCI would have a material financial effect upon TCI and
(ii) the information required to be supplied in a post-effective amendment by
this paragraph 8 is not contained in periodic reports filed by TCI pursuant to
section 13 or section 15(d) of the Securities Exchange Act of 1934 that are
incorporated by reference in the registration statement.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of TCI
pursuant to the foregoing provisions or otherwise, TCI has been advised that in
the opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Securities Act of 1933 and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by TCI of expenses incurred or paid by
a director, officer or controlling person of TCI in the successful defense of
any action, suit or proceeding) is asserted by such director, officer or
controlling person in connection with the securities being registered, TCI will,
unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act of 1933 and will be governed by the final adjudication of such
issue.
