            2.1. The Restructuring. (a) Subject to the terms and conditions of

without creating any deferred intercompany gain or other tax consequences, in a
manner reasonably satisfactory to Parent.

            (b) To the extent practicable prior to the Effective Time, and
subject to the reasonable satisfaction of Parent with the form and substance of
such transactions, the Company shall use its reasonable best efforts to cause

VIII to be satisfied prior to the Closing have been satisfied or duly waived,
the Company and its appropriate Affiliates shall, on a tax-free basis, make such
other transfers of assets and businesses, and assumptions of liabilities, if
any, as are reasonably necessary in order to cause the representations and
warranties in Section 5.17 to be true and correct in all material respects.

The actions described in this Section 2.1 are collectively referred to as the
"Restructuring."

            2.2. The Merger. Subject to the terms and conditions of this

Delaware. At the election of Parent, any direct Wholly Owned Subsidiary of
Parent with respect to which the representation and warranty set forth in

                                   ARTICLE IV

                       SHARE CONSIDERATION; CONVERSION OR
                      CANCELLATION OF SHARES IN THE MERGER

            4.1. Share Consideration; Conversion or Cancellation of Shares in
the Merger. Subject to the provisions of this Article IV, at the Effective Time,
by virtue of the Merger and without any action on the part of the holders
thereof, the shares of the constituent corporations shall be converted or
cancelled as follows:

            (a) Each share of TCI Group Class A Stock issued and outstanding
      immediately prior to the Effective Time shall be converted into the right
      to receive .7757 of a Parent Common Share (the "TCI Group A Exchange
      Ratio") and each share of TCI Group Class B Stock issued and outstanding
      immediately prior to the Effective Time shall be converted into the right
      to receive .8533 of a Parent Common Share (the "TCI Group B Exchange
      Ratio" and, together with the TCI Group A Exchange Ratio, the "TCI Group
      Exchange Ratios"). If, prior to the Effective Time, Parent should split or
      combine the Parent Common Shares, or pay a stock dividend or other stock
      distribution in Parent Common Shares, or otherwise effect any transaction
      that changes the Parent Common Shares into any other securities (including
      securities of another corporation), or make any other dividend or
      distribution on the Parent Common Shares (other than normal quarterly cash
      dividends as the same may be adjusted from time to time in the ordinary
      course consistent with past practice), then the TCI Group Exchange Ratios
      and the terms of the foregoing exchanges will be appropriately adjusted to
      reflect such split, combination, transaction, dividend or other
      distribution or change.

            (b) Each share of Liberty Media Class A Stock issued and outstanding
      immediately prior to the Effective Time shall be converted into the right
      to receive one share of Parent Liberty Class A Stock (the "Liberty Media
      Class A Exchange Ratio") and each share of Liberty Media Class B Stock
      issued and outstanding immediately prior to the Effective Time shall be
      converted into the right to receive one share of Parent Liberty Class B
      Stock (the "Liberty Media Class B Exchange Ratio" and, together with the
      Liberty Media Class A Exchange Ratio, the "Liberty Media Exchange
      Ratios"). If, prior to the Effective Time, Parent should effect any
      transaction that changes the Parent Common Shares into the securities of
      another corporation, the

                                       16
<PAGE>
      
      Liberty Media Exchange Ratios and the terms of the foregoing exchanges 
      will be appropriately adjusted to provide for the issuance of shares of 
      such other corporation having terms identical to the appropriate series of
      Parent Liberty Tracking Shares.
     
            (c) To the extent that any TCI Ventures Tracking Shares remain
      outstanding as of the Effective Time, each share of TCI Ventures Class A
      Stock issued and outstanding immediately prior to the Effective Time shall
      be converted into the right to receive .52 of a share of Parent Liberty
      Class A Stock (the "TCI Ventures Class A Exchange Ratio") and each share
      of TCI Ventures Class B Stock issued and outstanding immediately prior to
      the Effective Time shall be converted into the right to receive .52 of a
      share of Parent Liberty Class B Stock (the "TCI Ventures Class B Exchange
      Ratio" and, together with the TCI Ventures Class A Exchange Ratio, the
      "TCI Ventures Exchange Ratios"); provided that the Company may, in its
      discretion, adjust the TCI Ventures Exchange Ratios as it deems
      appropriate to reflect the relative values of the TCI Ventures Group and
      the Liberty Media Group. If, prior to the Effective Time, Parent should
      effect any transaction that changes the Parent Common Shares into the
      securities of another corporation, the Liberty Media Exchange Ratios and
      the terms of the foregoing exchanges will be appropriately adjusted to
      provide for the issuance of shares of such other corporation having terms
      identical to the appropriate series of Parent Liberty Tracking Shares.

            (d) All Shares converted into the right to receive Parent Common
      Shares or Parent Liberty Tracking Shares pursuant to this Section 4.1
      shall cease to be outstanding, shall be canceled and retired and shall
      cease to exist, and each holder of a certificate representing any such
      Shares shall thereafter cease to have any rights with respect to such
      Shares, except the right to receive for each of the Shares, upon the
      surrender of such certificate in accordance with Section 4.2, (i) in the
      case of each series of TCI Group Shares, the amount of Parent Common
      Shares with respect to each such series specified above (the "TCI Group
      Share Consideration") and cash in lieu of fractional Parent Common Shares
      as contemplated by Section 4.3, (ii) in the case of Liberty Media Tracking
      Shares, the amount of Parent Liberty Tracking Shares specified above (the
      "Liberty Media Share Consideration") and cash in lieu of fractional Parent
      Liberty Tracking Shares as contemplated by Section 4.3 and (iii) in the
      case of TCI Ventures Tracking Shares, if applicable, the amount of Parent
      Liberty Tracking Shares specified above (the "TCI Ventures Share
      Consideration") and cash in lieu of fractional Parent Liberty Tracking
      Shares as contemplated by Section 4.3.

                                       17

            (e) Each share of Common Stock, par value $0.01 per share, of Merger
      Sub issued and outstanding immediately prior to the Effective Time shall
      be converted into one share of common stock, par value $0.01 per share, of
      the Surviving Corporation.

            (f) (i) Each of the then outstanding stock options, if any, to
      purchase TCI Group Shares (each, a "TCI Group Option") issued by the
      Company pursuant to any stock option or similar plan of the Company, and
      any non-plan options to acquire TCI Group Shares set forth in Section 5.6
      of the Company Disclosure Statement 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 Parent and converted into a option (a "Parent
      Common Option") to purchase that number of Parent Common Shares determined
      by multiplying the number of TCI Group Shares subject to such TCI Group
      Option at the Effective Time by the appropriate TCI Group Exchange Ratio,
      at an exercise price per Parent Common Share equal to the exercise price
      per share of such TCI Group Option immediately prior to the Effective Time
      divided by such TCI Group Exchange Ratio, rounded down to the nearest
      whole cent. If the foregoing calculation results in an assumed TCI Group
      Option being exercisable for a fraction of a Parent Common Share, then the
      number of Parent Common Shares 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 Parent Common Option
      shall otherwise remain as set forth in the TCI Group Option converted into
      such Parent Common Option.

            (ii) Each of the then outstanding stock options, if any, to purchase
      Liberty Media Tracking Shares (each, a "Liberty Media Option") issued by
      the Company pursuant to any stock option or similar plan of the Company,
      and any non-plan options to acquire Liberty Media Tracking Shares set
      forth in Section 5.6 of the Company Disclosure Statement 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 Parent and converted into an
      option (a "Parent Liberty Tracking Option") to purchase a number of Parent
      Liberty Tracking Shares equal to the number of Liberty Media Tracking
      Shares subject to such Liberty Media Option at the Effective Time, at an
      exercise price per Parent Liberty Tracking Share equal to the exercise
      price per share of such Liberty Media Option immediately prior to the
      Effective Time. The terms and conditions of each Parent Liberty Tracking
      Option shall otherwise remain as set forth in the Liberty Media Option
      converted into such Parent Liberty Tracking Option.

                                       18
<PAGE>

            (iii) Each of the then outstanding stock options, if any, to
      purchase TCI Ventures Tracking Shares (each, a "TCI Ventures Option")
      issued by the Company pursuant to any stock option or similar plan of the
      Company, and any non-plan options to acquire TCI Ventures Tracking Shares
      set forth in Section 5.6 of the Company Disclosure Statement 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 Parent and converted into a
      Parent Liberty Tracking Option to purchase that number of Parent Liberty
      Tracking Shares determined by multiplying the number of TCI Ventures
      Tracking Shares subject to such TCI Ventures Option at the Effective Time
      by the appropriate TCI Ventures Exchange Ratio, at an exercise price per
      Parent Liberty Tracking Share equal to the exercise price per share of
      such TCI Ventures Option immediately prior to the Effective Time divided
      by such TCI Ventures Exchange Ratio, rounded down to the nearest whole
      cent. If the foregoing calculation results in an assumed TCI Ventures
      Option being exercisable for a fraction of a Parent Liberty Tracking
      Share, then the number of Parent Liberty Tracking Shares 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 Parent Liberty Tracking Option shall otherwise remain as set forth in
      the TCI Ventures Option converted into such Parent Liberty Tracking
      Option.

            (iv) The adjustment provided herein with respect to any options
      which are "incentive stock options" (as defined in Section 422 of the
      Code) shall be and is intended to be effected in a manner which is
      consistent with Section 424(a) of the Code.

            (v) All restricted Shares granted pursuant to any Employee Plan or
      Benefit Arrangement, and all individual awards of restricted Shares not
      granted pursuant to any Employee Plan or Benefit Arrangement, shall be
      converted into restricted Parent Common Shares or Parent Liberty Tracking
      Shares, as the case may be, pursuant to this Section 4.1 and will remain
      subject to the same restrictions applicable to such restricted Shares
      immediately prior to the Effective Time.

            (vi) The Company shall take all action necessary to provide that all
      outstanding awards of any type granted pursuant to any Employee Plan or
      Benefit Arrangement, and all outstanding individual awards not granted
      pursuant to any Employee Plan or Benefit Arrangement, will not vest or
      become exercisable on an accelerated basis in connection

                                       19

      with the Merger and will not terminate if not exercised prior to the
      Closing Date.
     
            (g) Each share of Company Class B Junior Preferred Stock issued and
      outstanding immediately prior to the Effective Time, other than any shares
      with respect to which appraisal rights are perfected under the DGCL, shall
      remain outstanding in the Merger as one share of Class B Junior Preferred
      Stock of the Surviving Corporation.

            (h) Each share of Series C-TCI Group Preferred Stock issued and
      outstanding immediately prior to the Effective Time, other than any shares
      with respect to which appraisal rights are perfected under the DGCL, shall
      be converted into the right to receive a number of Parent Common Shares
      equal to the product of (i) the Series C-TCI Group Preferred Conversion
      Rate, and (ii) the TCI Group A Exchange Ratio (the "Series C-TCI Group
      Preferred Exchange Ratio").

            (i) Each share of Series C-Liberty Media Preferred Stock issued and
      outstanding immediately prior to the Effective Time shall be converted
      into the right to receive a number of shares of Parent Liberty Class A
      Stock equal to the product of (i)the Series C-Liberty Media Conversion
      Rate, and (ii) the Liberty Media Class A Exchange Ratio (the "Series
      C-Liberty Media Exchange Ratio").

            (j) Each share of Series G Preferred Stock issued and outstanding
      immediately prior to the Effective Time, other than any shares with
      respect to which appraisal rights are perfected under the DGCL, shall be
      converted into the right to receive a number of Parent Common Shares equal
      to the product of (i) the Series G Conversion Rate, and (ii) the TCI Group
      A Exchange Ratio (the "Series G Preferred Ratio").

            (k) Each share of Series H Preferred Stock issued and outstanding
      immediately prior to the Effective Time shall be converted into the right
      to receive a number of shares of Parent Liberty Class A Stock equal to the
      product of (i)the Series H Conversion Rate, and (ii) the Liberty Media
      Class A Exchange Ratio (the "Series H Preferred Ratio").

            (l) If, prior to the Effective Time, Parent should split or combine
      the Parent Common Shares, or pay a stock dividend or other stock
      distribution in Parent Common Shares, or otherwise effect any transaction
      that changes the Parent Common Shares into any other securities (including
      securities of another corporation), or make any other dividend or
      distribution on the Parent Common Shares (other than normal quarterly cash
      dividends as the same 

                                       20

      may be adjusted from time to time in the ordinary course consistent with
      past practice), the Series Preferred Exchange Ratios and the terms of the
      exchanges described in Sections 4.1(h) through (k) will be appropriately
      adjusted to provide for the issuance of shares of such other corporation
      having terms substantially identical to the Parent Common Shares or
      identical to the appropriate series of Parent Liberty Tracking Shares, as
      appropriate.
     
            4.2. Payment for Shares in the Merger. The manner of making payment
for Shares in the Merger shall be as follows:

            (a) At the Effective Time, Parent shall make available to an
      exchange agent selected by Parent and reasonably acceptable to the Company
      (the "Exchange Agent"), (i) for the benefit of those Persons who
      immediately prior to the Effective Time were the holders of TCI Group
      Shares, a sufficient number of certificates representing Parent Common
      Shares required to effect the delivery of the aggregate TCI Group Share
      Consideration required to be issued pursuant to Section 4.1 (the
      certificates representing Parent Common Shares comprising such aggregate
      TCI Group Share Consideration being hereinafter referred to as the "TCI

      immediately prior to the Effective Time were the holders of Liberty Media
      Tracking Shares, a sufficient number of certificates representing the
      appropriate series of Parent Liberty Tracking Shares required to effect
      the delivery of the aggregate Liberty Media Share Consideration required

      Liberty Tracking Shares comprising such aggregate Liberty Media Share
      Consideration being hereinafter referred to as the "Liberty Media Exchange
      Fund"), and (iii) if applicable, for the benefit of those Persons who
      immediately prior to the Effective Time were the holders of TCI Ventures

      the delivery of the aggregate TCI Ventures Share Consideration required to
      be issued pursuant to Section 4.1 (the certificates representing Parent
      Liberty Tracking Shares comprising such aggregate TCI Ventures Share
      Consideration being hereinafter referred to as the "TCI Ventures Exchange
      Fund"). The Exchange Agent shall, pursuant to irrevocable instructions,
      deliver the Parent Common Shares and the Parent Liberty Tracking Shares

                                       21
<PAGE>

            (b) (i) Promptly after the Effective Time, the Exchange Agent shall
      mail to each holder of record of a certificate or certificates which
      immediately prior to the Effective Time represented outstanding TCI Group
      Shares (the "TCI Group Certificates") (1) a form of letter of transmittal
      (which shall specify that delivery shall be effected, and risk of loss and
      title to the TCI Group Certificates shall pass, only upon proper delivery
      of the TCI Group Certificates to the Exchange Agent) and (2) instructions
      for use in effecting the surrender of the TCI Group Certificates for
      payment therefor. Upon surrender of TCI Group Certificates for
      cancellation to the Exchange Agent, together with such letter of
      transmittal duly executed and any other required documents, the holder of
      such TCI Group Certificates shall be entitled to receive for each of the
      TCI Group Shares represented by such TCI Group Certificates the
      appropriate TCI Group Share Consideration and the TCI Group Certificates
      so surrendered shall forthwith be canceled. Until so surrendered, TCI
      Group Certificates shall represent solely the right to receive the
      appropriate TCI Group Share Consideration and any cash in lieu of
      fractional Parent Common Shares as contemplated by Section 4.3 with
      respect to each of the TCI Group Shares represented thereby. No dividends
      or other distributions that are declared on the Parent Common Shares and
      payable to the holders of record thereof after the Effective Time will be
      paid to Persons entitled by reason of the Merger to receive Parent Common
      Shares until such Persons surrender their TCI Group Certificates. Upon
      such surrender, there shall be paid to the Person in whose name the Parent
      Common Shares are issued any dividends or other distributions having a
      record date after the Effective Time and payable with respect to such
      Parent Common Shares between the Effective Time and the time of such
      surrender. After such surrender, there shall be paid on the applicable
      payment date, to the Person in whose name the Parent Common Shares are
      issued, any dividends or other distributions on such Parent Common Shares,
      as applicable, which shall have a record date after the Effective Time and
      prior to such surrender and a payment date after such surrender. In no
      event shall the Persons entitled to receive such dividends or other
      distributions be entitled to receive interest on such dividends or other
      distributions.

                  (ii) Promptly after the Effective Time, the Exchange Agent
      shall mail to each holder of record of a certificate or certificates which
      immediately prior to the Effective Time represented outstanding Liberty
      Media Tracking Shares (the "Liberty Media Certificates") (1) a form of
      letter of transmittal (which shall specify that delivery shall be
      effected, and risk of loss and title to the Liberty Media Certificates
      shall pass, only upon proper delivery of the Liberty Media Certificates to
      the 

                                       22
<PAGE>

      Exchange Agent) and (2) instructions for use in effecting the
      surrender of the Liberty Media Certificates for payment therefor. Upon
      surrender of Liberty Media Certificates for cancellation to the Exchange
      Agent, together with such letter of transmittal duly executed and any
      other required documents, the holder of such Liberty Media Certificates
      shall be entitled to receive for each of the Liberty Media Tracking Shares
      represented by such Liberty Media Certificates the appropriate Liberty
      Media Share Consideration and the Liberty Media Certificates so
      surrendered shall forthwith be canceled. Until so surrendered, Liberty
      Media Certificates shall represent solely the right to receive the
      appropriate Liberty Media Share Consideration and any cash in lieu of
      fractional Parent Liberty Tracking Shares as contemplated by Section 4.3
      with respect to each of the Liberty Media Tracking Shares represented
      thereby. No dividends or other distributions that are declared on the
      Parent Liberty Tracking Shares and payable to the holders of record
      thereof after the Effective Time will be paid to Persons entitled by
      reason of the Merger to receive Parent Liberty Tracking Shares until such
      Persons surrender their Liberty Media Certificates. Upon such surrender,
      there shall be paid to the Person in whose name the Parent Liberty
      Tracking Shares are issued any dividends or other distributions having a
      record date after the Effective Time and payable with respect to such
      Parent Liberty Tracking Shares between the Effective Time and the time of
      such surrender. After such surrender, there shall be paid on the
      applicable payment date, to the Person in whose name the Parent Liberty
      Tracking Shares are issued, any dividends or other distributions on such
      Parent Liberty Tracking Shares, as applicable, which shall have a record
      date after the Effective Time and prior to such surrender and a payment
      date after such surrender. In no event shall the Persons entitled to
      receive such dividends or other distributions be entitled to receive
      interest on such dividends or other distributions.

                  (iii) Promptly after the Effective Time, the Exchange Agent
      shall mail to each holder of record, if any, of a certificate or
      certificates which immediately prior to the Effective Time represented
      outstanding TCI Ventures Tracking Shares (the "TCI Ventures Certificates")
      (1) a form of letter of transmittal (which shall specify that delivery
      shall be effected, and risk of loss and title to the TCI Ventures
      Certificates shall pass, only upon proper delivery of the TCI Ventures
      Certificates to the Exchange Agent) and (2) instructions for use in
      effecting the surrender of the TCI Ventures Certificates for payment
      therefor. Upon surrender of TCI Ventures Certificates for cancellation to
      the Exchange Agent, together with such letter of transmittal duly executed
      and any

                                       23
<PAGE>

      other required documents, the holder of such TCI Ventures Certificates
      shall be entitled to receive for each of the TCI Ventures Tracking Shares
      represented by such TCI Ventures Certificates the appropriate TCI Ventures
      Share Consideration and the TCI Ventures Certificates so surrendered shall
      forthwith be canceled. Until so surrendered, TCI Ventures Certificates
      shall represent solely the right to receive the appropriate TCI Ventures
      Share Consideration and any cash in lieu of fractional Parent Liberty
      Tracking Shares as contemplated by Section 4.3 with respect to each of the
      TCI Ventures Tracking Shares represented thereby. No dividends or other
      distributions that are declared on the Parent Liberty Tracking Shares and
      payable to the holders of record thereof after the Effective Time will be
      paid to Persons entitled by reason of the Merger to receive Parent Liberty
      Tracking Shares until such Persons surrender their TCI Ventures
      Certificates. Upon such surrender, there shall be paid to the Person in
      whose name the Parent Liberty Tracking Shares are issued any dividends or
      other distributions having a record date after the Effective Time and
      payable with respect to such Parent Liberty Tracking Shares between the
      Effective Time and the time of such surrender. After such surrender, there
      shall be paid on the applicable payment date, to the Person in whose name
      the Parent Liberty Tracking Shares are issued, any dividends or other
      distributions on such Parent Liberty Tracking Shares, as applicable, which
      shall have a record date after the Effective Time and prior to such
      surrender and a payment date after such surrender. In no event shall the
      Persons entitled to receive such dividends or other distributions be
      entitled to receive interest on such dividends or other distributions.
     
                  (iv) If any cash or any certificate representing Parent Common
      Shares or Parent Liberty Tracking Shares is to be paid to or issued in a
      name other than that in which the Certificate surrendered in exchange
      therefor is registered, it shall be a condition of such exchange that the
      Certificate so surrendered shall be properly endorsed and otherwise in
      proper form for transfer and that the Person requesting such exchange
      shall pay to the Exchange Agent any transfer or other taxes required by
      reason of the issuance of certificates for such Parent Common Shares or
      Parent Liberty Tracking Shares, as applicable, in a name other than that
      of the registered holder of the Certificate surrendered, or shall
      establish to the reasonable satisfaction of the Exchange Agent that such
      tax has been paid or is not applicable. Notwithstanding the foregoing,
      neither the Exchange Agent nor any party hereto shall be liable to a
      holder of Shares for any Parent Common Shares or Parent Liberty Tracking
      Shares, as applicable, or dividends thereon or other distributions with
      respect thereto 

                                       24
<PAGE>

      or, in accordance with Section 4.3, proceeds of the sale of fractional
      interests, delivered to a public official pursuant to applicable escheat
      law. The Exchange Agent shall not be entitled to vote or exercise any
      rights of ownership with respect to the Parent Common Shares or Parent
      Liberty Tracking Shares held by it from time to time hereunder, except

      the account of the Persons entitled thereto.

      Shares, as applicable, until Parent has received a written agreement from
      such Person as provided in Section 7.9.

            (d) Any portion of the applicable Exchange Fund and the applicable
      Fractional Fund (and any dividends or other distributions with respect to
      such portion of the applicable Exchange Fund) which remains unclaimed by
      the former stockholders of the Company for one year after the Effective
      Time shall be delivered to Parent, upon demand of Parent, and any former
      stockholders of the Company shall thereafter look only to Parent for
      payment of their claim for the applicable Share Consideration (and any
      such dividends or other distributions) or for any cash in lieu of
      fractional Parent Common Shares or Parent Liberty Tracking Shares, as
      applicable.

            (e) In the event that any Certificate has 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 and, if required
      by the Surviving Corporation, the posting by such Person of a bond in such
      reasonable amount as Parent may direct as indemnity against any claim that
      may be made against it with respect to such Certificate, Parent will, in
      exchange for such lost, stolen or destroyed Certificate, issue or cause to
      be issued the number of Parent Common Shares or Parent Liberty Tracking
      Shares, as applicable, and pay or cause to be paid any amounts deliverable
      in respect thereof pursuant to this Article IV.

            4.3. Fractional Shares. (a) No fractional Parent Common Shares shall

Parent Common Share upon surrender of TCI Group Certificates for exchange
pursuant to this Article IV will be paid an amount in cash (without interest)
equal to such holder's proportionate 

                                       25
<PAGE>

interest in the net proceeds from the sale or sales in the open market by the
Exchange Agent, on behalf of all such holders, of the aggregate fractional
Parent Common Shares issued pursuant to this Article IV. As soon as practicable
following the Effective Time, the Exchange Agent shall determine the excess of
(i) the number of full Parent Common Shares delivered to the Exchange Agent by
Parent over (ii) the aggregate number of full Parent Common Shares to be
distributed to holders of TCI Group Shares (such excess being herein called the
"Excess Parent Common Shares"). The Exchange Agent, as agent for the former
holders of TCI Group Shares, shall sell the Excess Parent Common Shares at the
prevailing prices on the NYSE. The sales of the Excess Parent Common Shares by
the Exchange Agent shall be executed on the NYSE through one or more member
firms of the NYSE and shall be executed in round lots to the extent practicable.
Parent shall pay all commissions, transfer taxes and other out-of-pocket
transaction costs, including the expenses and compensation of the Exchange
Agent, incurred in connection with such sale of Excess Parent Common Shares.
Until the net proceeds of such sale have been distributed to the former holders
of TCI Group Shares, the Exchange Agent will hold such proceeds in trust for
such former holders (the "Fractional Parent Common Fund"). As soon as
practicable after the determination of the amount of cash to be paid to former
holders of TCI Group Shares in lieu of any fractional interests, the Exchange
Agent shall make available in accordance with this Agreement such amounts to
such former holders.

            (b) No fractional Parent Liberty Tracking Shares shall be issued in
the Merger to any former holder of Liberty Media Tracking Shares. In lieu of any
such fractional securities, each holder of Liberty Media Tracking Shares who
would otherwise have been entitled to a fraction of a Parent Liberty Tracking
Share upon surrender of Liberty Media Certificates for exchange pursuant to this
Article IV will be paid an amount in cash (without interest) equal to such
holder's proportionate interest in the net proceeds from the sale or sales in
the open market by the Exchange Agent, on behalf of all such holders, of the
aggregate fractional Parent Liberty Tracking Shares attributable to the Liberty
Media Tracking Shares and issued pursuant to this Article IV. As soon as
practicable following the Effective Time, the Exchange Agent shall determine the
excess of (i) the number of full Parent Liberty Tracking Shares delivered to the
Exchange Agent by Parent over (ii) the aggregate number of full Parent Liberty
Tracking Shares to be distributed to holders of Liberty Media Tracking Shares
(such excess being herein called the "Excess Parent Liberty Tracking (Liberty)
Shares"). The Exchange Agent, as agent for the former holders of Liberty Media
Tracking Shares, shall sell the Excess Parent Liberty Tracking (Liberty) Shares
at the prevailing prices on the NYSE (or on such other exchange or trading
system on which the Parent Liberty Tracking Shares are authorized). The sales of
the Excess Parent Liberty Tracking (Liberty) Shares by the 

                                       26
<PAGE>

Exchange Agent shall be executed in such manner as determined reasonably by the
Exchange Agent. Parent shall pay all commissions, transfer taxes and other
out-of-pocket transaction costs, including the expenses and compensation of the
Exchange Agent, incurred in connection with such sale of Excess Parent Liberty
Tracking (Liberty) Shares. Until the net proceeds of such sale have been
distributed to the former holders of Liberty Media Tracking Shares, the Exchange
Agent will hold such proceeds in trust for such former holders (the "Fractional
Parent Liberty Tracking (Liberty) Fund"). As soon as practicable after the
determination of the amount of cash to be paid to former holders of Liberty
Media Tracking Shares in lieu of any fractional interests, the Exchange Agent
shall make available in accordance with this Agreement such amounts to such
former holders.

            (c) If applicable, no fractional Parent Liberty Tracking Shares
shall be issued in the Merger to any former holder of TCI Ventures Tracking
Shares. In lieu of any such fractional securities, each holder of TCI Ventures
Tracking Shares who would otherwise have been entitled to a fraction of a Parent
Liberty Tracking Share upon surrender of TCI Ventures Certificates for exchange
pursuant to this Article IV will be paid an amount in cash (without interest)
equal to such holder's proportionate interest in the net proceeds from the sale
or sales in the open market by the Exchange Agent, on behalf of all such
holders, of the aggregate fractional Parent Liberty Tracking Shares attributable
to the TCI Ventures Tracking Shares and issued pursuant to this Article IV. As
soon as practicable following the Effective Time, the Exchange Agent shall
determine the excess of (i) the number of full Parent Liberty Tracking Shares
delivered to the Exchange Agent by Parent over (ii) the aggregate number of full
Parent Liberty Tracking Shares to be distributed to holders of TCI Ventures
Tracking Shares (such excess being herein called the "Excess Parent Liberty
Tracking (Ventures) Shares"). The Exchange Agent, as agent for the former
holders of TCI Ventures Tracking Shares, shall sell the Excess Parent Liberty
Tracking (Ventures) Shares at the prevailing prices on the NYSE (or on such
other exchange or trading system on which the Parent Liberty Tracking Shares are
authorized). The sales of the Excess Parent Liberty Tracking (Ventures) Shares
by the Exchange Agent shall be executed in such manner as determined reasonable
by the Exchange Agent. Parent shall pay all commissions, transfer taxes and
other out-of-pocket transaction costs, including the expenses and compensation
of the Exchange Agent, incurred in connection with such sale of Excess Parent
Liberty Tracking (Ventures) Shares. Until the net proceeds of such sale have
been distributed to the former holders of TCI Ventures Tracking Shares, the
Exchange Agent will hold such proceeds in trust for such former holders (the
"Fractional Parent Liberty Tracking (Ventures) Fund"). As soon as practicable
after the determination of the amount of cash to be paid to former holders of
TCI 

                                       27
<PAGE>

Ventures Tracking Shares in lieu of any fractional interests, the Exchange
Agent shall make available in accordance with this Agreement such amounts to
such former holders.

            4.4. Transfer of Shares after the Effective Time. No transfers of
Shares shall be made on the stock transfer books of the Company after the close
of business on the day prior to the date of the Effective Time.

            4.5. Treatment of Series F Preferred Stock. Prior to the Effective
Time, the Company shall take all action necessary either (a) to cause each share
of Series F Preferred Stock beneficially owned by it or any of its Subsidiaries
to be converted into 1,496.65 shares of TCI Group Class A Stock in accordance
with the terms of the Company Charter, or (b) to redeem all shares of Series F
Preferred Stock in exchange for an aggregate of 416,528,172 shares of TCI Group
Class A Stock, plus any additional shares of TCI Group Class A Stock issuable in
accordance with the Company Charter as a result of the accrual of dividends
thereon after the date hereof.

            4.6. Company Series Preferred Stock. After the Effective Time,
Parent and the Surviving Corporation shall establish reasonable procedures to
facilitate the exchange of the Company Series Preferred Stock for Parent Common
Shares or Parent Liberty Tracking Shares as contemplated by Sections 4.1(g)
through (l). All shares of Company Series Preferred Stock converted into the
right to receive Parent Common Shares or Parent Liberty Tracking Shares pursuant
to Section 4.1 shall cease to be outstanding, shall be canceled and retired and
shall cease to exist, and each holder of a certificate representing any such
shares of Company Series Preferred Stock shall thereafter cease to have any
rights with respect to such shares of Company Series Preferred Stock, except the
right to receive therefor, upon the surrender of such certificate in accordance
with such procedures, the Parent Common Shares or Parent Liberty Tracking Shares
specified therein and cash in lieu of any fractional shares as reasonably
determined by the Surviving Corporation.

                                    ARTICLE V

                REPRESENTATIONS AND WARRANTIES OF THE COMPANY

            The Company hereby represents and warrants to Parent and Merger Sub
that, except as set forth in the Company Disclosure Statement:

            5.1. Organization, Etc. of the Company. The Company is a corporation
duly organized, validly existing and in good standing under the laws of the
State of Delaware and has all 

                                       28
<PAGE>

requisite corporate power and authority to own, lease and operate its properties
and to carry on its business as now conducted and proposed by the Company to be
conducted. The Company is duly qualified and in good standing 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 necessary and where the
failure to be so qualified or in good standing has or would have, individually
or in the aggregate, a Material Adverse Effect on the Company or on the TCI
Group.

            5.2. Subsidiaries. Section 5.2 of the Company Disclosure Statement
contains a complete and accurate list of all of the Subsidiaries of the Company
(by Group) as of the date hereof. Each Subsidiary of the Company (a) is a
corporation or other legal entity duly organized, validly existing and (if
applicable) in good standing under the laws of the jurisdiction of its
organization and has all requisite corporate, partnership or similar power and
authority to own its properties and conduct its business and operations as
currently conducted, except where the failure to be duly organized, validly
existing and in good standing or to have such power and authority does not and
would not have, individually or in the aggregate, a Material Adverse Effect on
the Company or on the TCI Group, and (b) is duly qualified and in good standing
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 necessary,
except where the failure to be so qualified or in good standing does not and
would not have, individually or in the aggregate, a Material Adverse Effect on
the Company or on the TCI Group.

            5.3. Agreement. The Company has all necessary corporate power and
authority to execute and deliver this Agreement, to perform its obligations
hereunder and to consummate the transactions contemplated hereby. This Agreement
and the consummation of the transactions contemplated hereby have been approved
by the Board of Directors of the Company and have been duly authorized by all
other necessary corporate action on the part of the Company, except for the
approval of the Company's stockholders contemplated by Section 7.3. This
Agreement has been duly executed and delivered by a duly authorized officer of
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. The Board
of Directors of the Company has approved the transactions contemplated by this
Agreement and the Voting Agreement, including the Merger, so as to render the
provisions of Section 203 of the DGCL inapplicable to the transactions
contemplated by this Agreement and to Parent and Merger Sub in connection with
this Agreement and the Voting Agreement. The Board of Directors of the Company

                                       29
<PAGE>

has directed that this Agreement be submitted to the stockholders of the Company
for their approval. The affirmative approval, by vote or written consent, of the
holders of Shares representing a majority of the votes that may be cast by the
holders of all outstanding Shares (voting as a single class) is the only vote of
the holders of any class or series of capital stock of the Company necessary to
adopt this Agreement and approve the Merger.

            5.4. Permits; Compliance. Each of the Company and its Subsidiaries
is in possession of all Permits from appropriate Governmental Bodies (including
the FCC) necessary for the Company or any of its Subsidiaries to own, lease and
operate its properties or to carry on their respective businesses as they are
now being conducted (the "Company Permits"), and all such Company Permits are
valid, and in full force and effect, except where the failure to have, or the
suspension or cancellation of, any of the Company Permits does not and would
not, individually or in the aggregate, (a) have a Material Adverse Effect on the
Company or on the TCI Group or (b) prevent or materially delay the consummation
of the Merger. No suspension or cancellation of any of the Company Permits is
pending or, to the knowledge of the Company, threatened, except where the
failure to have, or the suspension or cancellation of, any of the Company
Permits does not and would not, individually or in the aggregate, (x) have a
Material Adverse Effect on the Company or on the TCI Group or (y) prevent or
materially delay the consummation of the Merger. Neither the Company nor any of
its Subsidiaries is in conflict with, or in default or violation of, (i) any Law
applicable to the Company or any of its Subsidiaries or by which any property,
asset or operation of the Company or any of its Subsidiaries is bound or
affected or (ii) any Company Permits, except for such conflicts, defaults or
violations that do not and would not, individually or in the aggregate, (A) have

directors' and officers' liability policies), whether or not insured or funded
(each, a "Benefit Arrangement"). Except as disclosed on the Company Disclosure
Statement, neither the Company nor any of its Subsidiaries has any commitment to
establish any material additional Employee Plans or Benefit Arrangements or to
modify or change materially any existing Employee Plan or Benefit Arrangement.
The Company has made available to Parent with respect to each Employee Plan and
Benefit Arrangement: (i) a true and complete copy of all written documents
comprising such Employee Plan or Benefit Arrangement (including amendments and
individual agreements relating thereto) or, if there is no such written
document, an accurate and complete description of such Employee Plan or Benefit
Arrangement; (ii) the most recent Form 5500 or Form 5500-C (including all
schedules thereto), if applicable; (iii) the most recent financial statements
and actuarial reports, if any; (iv) the summary plan description currently in
effect and all material modifications thereof, if any; and (v) the most recent
Internal Revenue Service determination letter, if any. For purposes of the
Company Disclosure Statement and for making available documents with respect to
Employee Plans and Benefit Arrangements, but not for purposes of the remainder
of this Section 5.9, Employee Plans and Benefit Arrangements shall be limited to
Employee Plans and Benefit Arrangements of the Company and its ERISA Affiliates.

            (b) Each Employee Plan and Benefit Arrangement has been established
and maintained in accordance with its terms and in compliance with all
applicable Laws, including ERISA and the Code (and the prohibited transaction
provisions of ERISA and the Code), and all contributions required to be made to
the Employee Plans and Benefit Arrangements have been made in a timely fashion,
except where such failure to establish, maintain or comply, or to make such
contributions, individually or in the aggregate, does not and would not have a
Material Adverse Effect on the Company or on the TCI Group. Each Employee Plan
that is intended to be qualified under Section 401(a) of the Code has received a
favorable determination letter or is subject to a favorable notification letter
from the Internal 

                                       35
<PAGE>

Revenue Service, and, to the knowledge of the Company, no event has occurred
which results or would result in a revocation of such letter.

            (c) Except as set forth in Section 5.9 of the Company Disclosure
Statement, no Employee Plan is subject to Title IV of ERISA.

            (d) Except as set forth in Section 5.9 of the Company Disclosure
Statement, no Employee Plan is a "multiemployer plan" (as defined in Section
3(37) of ERISA) or a "multiple employer plan" described in Section 4063(a) of
ERISA, and the Company has not at any time in the past five years, contributed
to or been obligated to contribute to such a multiemployer plan or multiple
employer plan.

            (e) Neither the Company nor any ERISA Affiliate has any Controlled
Group Liability, nor do any circumstances exist that could result in any of them
having any Controlled Group Liability, which would have a Material Adverse
Effect on the Company or on the TCI Group. "Controlled Group Liability" means
any and all liabilities under (i) Title IV of ERISA, (ii) Section 302 of ERISA,
(iii) Sections 412 and 4971 of the Code, or (iv) the continuation coverage
requirements of Sections 601 et seq. of ERISA and section 4980B of the Code.

            (f) Except as set forth in Section 5.9 of the Company Disclosure
Statement, none of the execution or delivery of this Agreement, the Voting
Agreement, stockholder approval of the Merger by the stockholders of the Company
at the Company Stockholders Meeting or otherwise, or the consummation of the
transactions contemplated hereby or thereby (either alone or together with any
additional or subsequent events), constitutes an event under any Employee Plan,
Benefit Arrangement, loan to, or individual agreement or contract with, an
Employee that may result in any material payment (whether of severance pay or
otherwise), restriction or limitation upon the assets of any Employee Plan or
Benefit Agreement, acceleration of payment or vesting, increase in benefits or
compensation, or required funding, with respect to any Employee, or the
forgiveness of any loan or other commitment of any Employees.

            (g) There are no actions, suits, arbitrations, inquiries,
investigations or other proceedings (other than routine claims for benefits)
pending or, to the Company's knowledge, threatened, with respect to any Employee
Plan or Benefit Arrangement, except for any of the foregoing that do not and
would not have, individually or in the aggregate, a Material Adverse Effect on
the Company or on the TCI Group.

            (h) Except as disclosed on the Company Disclosure Statement, no
material amounts paid or payable by the Company or any ERISA Affiliate to or
with respect to any Employee 

                                       36
<PAGE>

(including any such amounts that may be payable as a result of the execution and
delivery of this Agreement or the Voting Agreement or the consummation of the
transactions contemplated hereby or thereby) will fail to be deductible for
United States federal income tax purposes by reason of Section 280G of the Code.

            (i) Except as set forth in Section 5.9 of the Company Disclosure
Statement, no Employees and no beneficiaries or dependents of Employees are
entitled under any Employee Plan or Benefit Arrangement to post-employment
welfare benefits of any kind, including death or medical benefits, other than
coverage mandated by Section 4980B of the Code.

            (j) Except as set forth in Section 5.9 of the Company Disclosure
Statement, there are no agreements with, or pending petitions for recognition
of, a labor union or association as the exclusive bargaining agent for any of
the employees of the Company or any of its Subsidiaries; no such petitions have
been pending at any time within two years of the date of this Agreement and, to
the knowledge of the Company, there has not been any organizing effort by any
union or other group seeking to represent any employees of the Company or any of
its Subsidiaries as their exclusive bargaining agent at any time within two
years of the date of this Agreement. There are no labor strikes, work stoppages
or other labor troubles, other than routine grievance matters, now pending, or,
to the Company's knowledge, threatened, against the Company or any of its
Subsidiaries which have or would have, individually or in the aggregate, a
Material Adverse Effect on the Company or on the TCI Group, and there have not
been any such labor strikes, work stoppages or other labor troubles, other than
routine grievance matters, with respect to the Company or any of its
Subsidiaries at any time within two years of the date of this Agreement.

            5.10. Taxes. (a) The Company and its Subsidiaries have filed all
income Tax Returns and all material other United States federal, state, county,
local and foreign Tax Returns required to be filed by them. The Company and its
Subsidiaries have paid all material Taxes due, other than Taxes appropriate
reserves for which have been made in the Company's financial statements (and, to
the extent material, such reserves have been accurately described in the Company
SEC Reports). There are no material assessments or adjustments that have been
asserted in writing against the Company or its Subsidiaries for any period for
which the Company has not made appropriate reserves in the Company's financial
statements included in the Company SEC Reports.

            (b) There are no material claims or assessments pending against the
Company or any of its Subsidiaries for any alleged deficiency in any Tax, and
the Company has not been 

                                       37
<PAGE>

notified in writing of any proposed material Tax claims or assessments against
the Company or any of its Subsidiaries (other than, in each case, claims or
assessments for which adequate reserves in the Company financial statements have
been established or which are being contested in good faith or are immaterial in
amount). Except as set forth in Section 5.10(b) of the Company Disclosure
Statement and subject to the qualifications set forth therein, there are no
material "deferred intercompany transactions" or "intercompany transactions" the
gain or loss in which has not yet been taken into account under the consolidated
return Treasury Regulations currently or previously in effect.

            (c) There are no liens for Taxes on the assets of the Company or any
of its Subsidiaries, except for statutory liens for current Taxes not yet due
and payable (and except for liens which do not and would not, individually or in
the aggregate, have a Material Adverse Effect on the Company or on the TCI
Group).

            (d) For purposes of this Agreement, the term "Tax" means any United
States federal, state, county or local, or foreign or provincial income, gross
receipts, property, sales, use, license, excise, franchise, employment, payroll,
value added, alternative or added minimum, ad valorem or transfer tax, or any
other tax, custom, duty or governmental fee or other like assessment or charge
of any kind whatsoever, together with any interest or penalty imposed by any
Governmental Body. The term "Tax Return" means a report, return or other
information (including any attached schedules or any amendments to such report,
return or other information) required to be supplied to or filed with a
Governmental Body with respect to any Tax, including an information return,
claim for refund, amended return or declaration or estimated Tax.

            5.11. Intellectual Property. The Company and its Subsidiaries own,
have the defensible right to use, or are indemnified for or otherwise protected
from any material risk for using, the Intellectual Property used in their
respective businesses, except where the failure to own, have the right to use or
be indemnified for or protected from any material risk of using such
Intellectual Property, individually or in the aggregate, does not and would not
have a Material Adverse Effect on the Company or on the TCI Group.

            5.12. Reports and Financial Statements. (a) The Company has filed
all Reports on Form 10-K, Form 10-Q and Form 8-K, registration statements and
proxy statements required to be filed with the SEC since January 1, 1996
(collectively, the "Company SEC Reports"). The Company has previously furnished
or made available to Parent true and complete copies of all the Company SEC
Reports filed prior to the date hereof. None of 

                                       38
<PAGE>

the Company SEC Reports, as of their respective dates, contained any untrue
statement of material fact or omitted to state a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading. Each of the
consolidated balance sheets (including the related notes) included in the
Company SEC Reports presents fairly, in all material respects, the consolidated
financial position of the Company and its Subsidiaries as of the respective
dates thereof, and the other related statements (including the related notes)
included in the Company SEC Reports present fairly, in all material respects,
the results of operations and the changes in financial position of the Company
and its Subsidiaries for the respective periods or as of the respective dates
set forth therein, all in conformity with generally accepted accounting
principles consistently applied during the periods involved, except as otherwise
noted therein and subject, in the case of the unaudited interim financial
statements, to normal year-end adjustments. All of the Company SEC Reports, as
of their respective dates, complied as to form in all material respects with the
requirements of the Exchange Act, the Securities Act and the applicable rules
and regulations thereunder.

            (b) The Company and its Subsidiaries have not made any misstatements
of fact, or omitted to disclose any fact, to any Governmental Body, or taken or
failed to take any action, which misstatements or omissions, actions or failures
to act, individually or in the aggregate, subject or would subject any Company
Permits referred to in Section 5.4 to revocation or failure to renew, except
where such revocation or failure to renew, individually or in the aggregate,
does not and would not have a Material Adverse Effect on the Company or on the
TCI Group.

            (c) Except (i) as and to the extent disclosed or reserved against on
the balance sheet of the Company as of December 31, 1997 included in the Company
SEC Reports, or (ii) as incurred after the date thereof in the ordinary course
of business consistent with prior practice and not prohibited by this Agreement,
the Company does not have any liabilities or obligations of any nature,
absolute, accrued, contingent or otherwise and whether due or to become due,
that, individually or in the aggregate, have or would have a Material Adverse
Effect on the Company or on the TCI Group.

            5.13. Absence of Certain Changes or Events. During the period since
December 31, 1997, except as disclosed in the Company SEC Reports filed prior to
the date hereof, (a) the business of the Company and its Subsidiaries has been
conducted only in the ordinary course, consistent with past practice, except for
the execution and delivery of this Agreement and the 

                                       39
<PAGE>

consummation of the transactions contemplated hereby, and except as otherwise
expressly permitted or required by this Agreement, (b) neither the Company nor
any of its Subsidiaries has taken any action or omitted to take any action, or
entered into any contract, agreement, commitment or arrangement to take any
action or omit to take any action, which, if taken or omitted after the date
hereof, would violate Section 7.1, and (c) there has not been, and, to the best
knowledge of the Company, nothing has occurred that would have, a Material
Adverse Effect on the Company or on the TCI Group.

            5.14. Affiliated Transactions and Certain Other Agreements. Set
forth in Section 5.14 of the Company Disclosure Statement is an accurate and
complete listing, as of the date hereof, of (a) all contracts, leases,
agreements or understandings, whether written or oral, to which the Company or
any of its Subsidiaries is a party or is otherwise bound which contain any
restriction or limitation on the ability of the Company or any of its Affiliates
(other than the Stockholders and their non-Company Affiliates) to engage in any
business anywhere in the world, other than any such contracts, leases,
agreements or understandings the loss or breach of which, individually or in the
aggregate, does not and would not have a Material Adverse Effect on the Company
or on the TCI Group, and (b) all contracts, leases, agreements or
understandings, whether written or oral, giving any Person the right to require
the Company to register Shares or to participate in any registration of Shares.

to Donaldson, Lufkin & Jenrette Securities Corporation, which fees and expenses
are reflected in its agreements with the Company, copies of which have been
furnished to Parent, the Company has not employed any investment banker, broker,
finder, consultant or intermediary in connection with the transactions
contemplated by this Agreement which would be entitled to any investment
banking, brokerage, finder's or similar fee or commission in connection with
this Agreement or the transactions contemplated hereby.

            5.16. Registration Statement. None of the information supplied or to
be supplied by the Company in writing for inclusion or incorporation by
reference in the Registration Statement will at the time it becomes effective,
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary in order to make the statements
therein not misleading. If at any time

                                       40

prior to the Effective Time any event with respect to the Company, its officers
and directors or any of its Subsidiaries shall occur which is required to be
described in an amendment of, or a supplement to the Registration Statement, the
Company shall notify Parent thereof by reference to this Section 5.16 and such
event shall be so described. Any such amendment or supplement shall be promptly
filed with the SEC and, as and to the extent required by law, disseminated to
the stockholders of the Company, and such amendment or supplement shall comply
in all material respects with all provisions of the Securities Act.

            5.17. Separation of Assets and Liabilities. (a) Each of the combined
balance sheets (including the related notes) of each of the TCI Group, the
Liberty Media Group and the TCI Ventures Group included in the Company SEC
Reports presents fairly, respectively, in all material respects, the combined
financial position of each of the TCI Group, the Liberty Media Group and the TCI
Ventures Group as of the respective dates thereof, and the other related
statements (including the related notes) included in the Company SEC Reports
present fairly, respectively, in all material respects, the results of
operations and the changes in financial position of each of the TCI Group, the
Liberty Media Group and the TCI Ventures Group for the respective periods or as

the TCI Ventures Group has any liabilities or obligations of any nature,
absolute, accrued, contingent or otherwise and whether due or to become due,
that, individually or in the aggregate, have or would have a Material Adverse
Effect on the Company or on the TCI Group.

            (b) Set forth in Section 5.17(b) of the Company Disclosure Statement
is an accurate and complete listing, as of the date hereof, of all contracts,
leases, agreements or understandings, whether written or oral, that are material

that, except as set forth in the Parent Disclosure Statement (each section of
which qualifies the correspondingly numbered representation and warranty or
covenant as specified therein):

            6.1. Organization, Etc. of Parent. Parent is a corporation duly
organized, validly existing and in good standing under the laws of the State of
New York and has all requisite corporate power and authority to own, lease and
operate its properties and to carry on its business as now conducted and
proposed by Parent to be conducted. Parent is duly qualified and in good
standing 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
necessary and where the failure to be so qualified or in good standing has or
would have, individually or in the aggregate, a Material Adverse Effect on
Parent.

            6.2. Subsidiaries. Each Subsidiary of Parent (a) is a corporation or
other legal entity duly organized, validly existing and (if applicable) in good

requisite corporate, partnership or similar power and authority to own its
properties and conduct its business and operations as currently conducted,

standing or to have such power and authority does not and would not have,
individually or in the aggregate, a Material Adverse Effect on Parent, and (b)
is duly qualified and in good standing in each jurisdiction in which the
property owned, leased or operated by it or the nature of the business conducted

hereby have been approved by the respective Boards of Directors of Parent and
Merger Sub and by Parent as the sole stockholder of Merger Sub, and have been
duly authorized by all other necessary corporate action on the part of Parent or
Merger Sub, except for the approval of the Parent's stockholders contemplated by

authorized officer of Parent and of Merger Sub and (assuming the due execution
and delivery of this 

                                       43

FCC) necessary for Parent or any of its Subsidiaries to own, lease and operate
its properties or to carry on their respective businesses as they are now being
conducted (the "Parent Permits"), and all such Parent Permits are valid, and in
full force and effect, except where the failure to have, or the suspension or
cancellation of, any of the Parent Permits does not and would not, individually
or in the aggregate, (a) have a Material Adverse Effect on Parent or (b) prevent
or materially delay the consummation of the Merger. No suspension or
cancellation of any of the Parent Permits is pending or, to the knowledge of
Parent, threatened, except where the failure to have, or the suspension or
cancellation of, any of the Parent Permits does not and would not, individually

any Parent Permits, except for such conflicts, defaults or violations that do
not and would not, individually or in the aggregate, (A) have a Material Adverse
Effect on Parent or (B) prevent or materially delay the consummation of the
Merger.

            6.5. Opinions of Parent's Financial Advisors. The Board of Directors
of Parent has received the opinions, dated as of the date of this Agreement, of

                                       44
<PAGE>

of any nature. As of the close of business on April 30, 1998, there were

and the Exchange Act and registered or exempt from registration under any
applicable state securities laws.

            6.8. Litigation. Except as disclosed in the Parent SEC Reports filed

Subsidiaries or any Benefit Plans of Parent or any of its Subsidiaries, or any
property of Parent or any such Subsidiary (including Intellectual Property), in
any court or before any arbitrator of any kind or in or before or by any
Governmental Body, except actions, suits, investigations or proceedings or
which, individually or in the aggregate, would not, if adversely determined, (a)
have a Material Adverse Effect on Parent or (b) prevent or materially delay the
consummation of the Merger.

            6.9. Compliance with Other Instruments, Etc. Neither Parent nor any
Subsidiary of Parent is in violation of any term of (a) its charter, by-laws or
other organizational documents, or (b) any agreement or instrument related to
indebtedness for borrowed money or any other agreement to which it is a party or
by which it is bound, the consequences of which violation, whether individually
or in the aggregate, do or would (i) have a Material Adverse Effect on Parent or
(ii) prevent or materially delay the consummation of the Merger. Assuming the
approval of Parent's stockholders as contemplated by Section 7.3, the execution,
delivery and performance of this Agreement and the consummation of the
transactions contemplated hereby will not result in any violation of or conflict
with, or constitute a default under, the charter, bylaws or other organizational
documents of Parent (or any of its Subsidiaries). Except as set forth in Section
6.9 of the Parent Disclosure Statement, the execution, delivery and performance
of this Agreement and the consummation of the transactions contemplated hereby
will not result in any violation of or conflict with, constitute a default
under, require any consent, waiver or notice under any term of, or result in the
reduction or loss of any benefit or the creation or acceleration of any
obligation

<PAGE>

or other obligation or any instrument to which Parent or any of its Subsidiaries
is a party or by which any of the assets or properties of Parent or any of its
Subsidiaries is bound or any instrument or Law, or result in the creation of (or
impose any obligation on Parent or any of its Subsidiaries to create) any
mortgage, lien, charge, security interest or other encumbrance upon any of the
properties or assets of Parent or any of its Subsidiaries pursuant to any such
term, except where any of the foregoing, individually or in the aggregate, does
not and would not (i) have a Material Adverse Effect on Parent or (ii) prevent
or materially delay the consummation of the Merger.

            6.10. Taxes. (a) Parent and its Subsidiaries have filed all income
Tax Returns and all material other United States federal, state, county, local
and foreign Tax Returns required to be filed by them. Parent and its
Subsidiaries have paid all material Taxes due, other than Taxes appropriate
reserves for which have been made in Parent's financial statements (and, to the
extent material, such reserves have been accurately described in the Parent SEC
Reports). There are no material assessments or adjustments that have been
asserted in writing against Parent or its Subsidiaries for any period for which
Parent has not made appropriate reserves in Parent's financial statements
included in Parent SEC Reports.

            (b) There are no material claims or assessments pending against
Parent or any of its Subsidiaries for any alleged deficiency in any Tax, and
Parent has not been notified in writing of any proposed material Tax claims or
assessments against Parent or any of its Subsidiaries (other than, in each case,
claims or assessments for which adequate reserves in Parent financial statements
have been established or which are being contested in good faith or are
immaterial in amount).

            (c) There are no liens for Taxes on the assets of Parent or any of
its Subsidiaries, except for statutory liens for current Taxes not yet due and
payable (and except for liens which do not and would not, individually or in the
aggregate, have a Material Adverse Effect on Parent).

            6.11. Intellectual Property. Parent and its Subsidiaries own, have
the defensible right to use, or are indemnified for or otherwise protected from
any material risk for using the Intellectual Property used in their respective
businesses, except where the failure to own, have the right to use or be
indemnified for or protected from any material risk of using such Intellectual
Property, individually or in the aggregate, does not and would not have a
Material Adverse Effect on Parent.

            6.12. Reports and Financial Statements. (a) Parent has filed all
Reports on Form 10-K, Form 10-Q and Form 8-K, registration statements and proxy
statements required to be filed with the SEC since January 1, 1996
(collectively, the "Parent SEC Reports"). Parent has previously furnished or
made available to the Company true and complete copies of all Parent SEC Reports
filed prior to the date hereof. None of the Parent SEC Reports, as of their
respective dates, contained any untrue statement of material fact or omitted to
state a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading. Each of the balance sheets (including the related notes)
included in the Parent SEC Reports presents fairly, in all material respects,
the consolidated financial position of Parent and its Subsidiaries as of the
respective dates thereof, and the other related statements (including the
related notes) included in the Parent SEC Reports present fairly, in all
material respects, the results of operations and the changes in financial
position of Parent and its Subsidiaries for the respective periods or as of the
respective dates set forth therein, all in conformity with generally accepted
accounting principles consistently applied during the periods involved, except
as otherwise noted therein and subject, in the case of the unaudited interim
financial statements, to normal year-end adjustments. All of the Parent SEC
Reports, as of their respective dates, complied as to form in all material
respects with the requirements of the Exchange Act, the Securities Act and the
applicable rules and regulations thereunder.

            (b) Parent and its Subsidiaries have not made any misstatements of
fact, or omitted to disclose any fact, to any Governmental Body, or taken or
failed to take any action, which misstatements or omissions, actions or failures
to act, individually or in the aggregate, subject or would subject any Parent
Permits referred to in Section 6.4 to revocation or failure to renew, except
where such revocation or failure to renew, individually or in the aggregate,
does not and would not have a Material Adverse Effect on Parent.

            (c) Except (i) as and to the extent disclosed or reserved against on
the balance sheet of Parent as of December 31, 1997 included in the Parent SEC
Reports, or (ii) as incurred after the date thereof in the ordinary course of
business consistent with prior practice and not prohibited by this Agreement,
Parent does not have any liabilities or obligations of any nature, absolute,
accrued, contingent or otherwise and whether due or to become due, that,
individually or in the aggregate, have or would have a Material Adverse Effect
on Parent.

            (d) During the period since December 31, 1997, except as disclosed
in the Parent SEC Reports filed prior to the 

                                       47
<PAGE>

date hereof, there has not been, and, to the best knowledge of Parent, nothing
has occurred that would have, a Material Adverse Effect on Parent.

            6.13. Brokers and Finders. Except for the fees and expenses payable
to Credit Suisse First Boston Corporation and Goldman Sachs & Co., which fees
and expenses will be paid by Parent, Parent has not employed any investment
banker, broker, finder, consultant or intermediary in connection with the
transactions contemplated by this Agreement which would be entitled to any
investment banking, brokerage, finder's or similar fee or commission in
connection with this Agreement or the transactions contemplated hereby.

            6.14. Registration Statement. None of the information to be supplied
by Parent or Merger Sub in writing for inclusion or incorporation by reference
in the Registration Statement will at the time it becomes effective, contain any
untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary in order to make the statements therein not
misleading. If at any time prior to the Effective Time any event with respect to
Parent, its officers and directors or any of its Subsidiaries shall occur which
is required to be described in an amendment of, or a supplement to the
Registration Statement, Parent shall notify the Company thereof by reference to
this Section 6.14 and such event shall be so described. Any such amendment or
supplement shall be promptly filed with the SEC and, as and to the extent
required by law, disseminated to the stockholders of the Company, and such
amendment or supplement shall comply in all material respects with all
provisions of the Securities Act. The Registration Statement will comply (with
respect to Parent and Merger Sub and information provided in writing therefor by
Parent or Merger Sub) as to form in all material respects with the provisions of
the Securities Act.

            6.15.  Ownership of Merger Sub; No Prior Activities; Assets of
Merger Sub.

            (a) Merger Sub was formed by Parent solely for the purpose of
engaging in the transactions contemplated hereby.

            (b) As of the date hereof and the Effective Time, the capital stock
of Merger Sub is and will be owned 100% by Parent directly. Further, there are
not as of the date hereof and there will not be at the Effective Time any
outstanding or authorized options, warrants, calls, rights, commitments or any
other agreements of any character to or by which Merger Sub is a party or may be
bound requiring it to issue, transfer, sell, purchase, redeem or acquire any
shares of capital stock or any securities or rights convertible into,
exchangeable for, or evidencing the right to subscribe for or acquire, any
shares of capital stock of Merger Sub.

                                       48
<PAGE>

            (c) As of the date hereof and immediately prior to the Effective
Time, except for obligations or liabilities incurred in connection with its
incorporation or organization and the transactions contemplated hereby and by
the Voting Agreement, Merger Sub has not and will not have incurred, directly or
indirectly through any Subsidiary or Affiliate, any obligations or liabilities
or engaged in any business or activities of any type or kind whatsoever or
entered into any agreements or arrangements with any Person.

            (d) Parent will take all action necessary to ensure that Merger Sub
at no time prior to the Effective Time owns any material assets other than an
amount of cash necessary to incorporate Merger Sub and to pay the expenses of
the Merger attributable to Merger Sub if the Merger is consummated.

            6.16. Ownership of Company Stock. Neither Parent nor any Subsidiary
of Parent (excluding any employee benefit plan, or related trust, of Parent or
its Subsidiaries) owns or, to the knowledge of Parent, has owned within the last
two years, any shares of the capital stock of the Company. Between the date of
this Agreement and the Effective Time, neither Parent nor any Subsidiary of
Parent (excluding any employee benefit plan, or related trust, of Parent or its
Subsidiaries) will purchase or otherwise acquire any shares of the capital stock
of the Company (except pursuant to the terms of this Agreement).

      amend or exercise discretion pursuant to any such Employee Plan or Benefit
      Arrangement in existence on the date hereof, except for any such amendment
      or exercise of discretion in the ordinary course of business, consistent

      however, that the foregoing shall not be applicable to any such payment or
      increase, or any such agreement, so long as the associated costs and
      expenses related thereto are attributed to the Liberty/Ventures Group; and
      provided, further, that the Company is expressly authorized to enter into
      tax protection agreements in the form set forth in Schedule 7.12(e) with
      those employees listed on Schedule 7.12(e);

      inactive Subsidiary (other than the Merger or as provided in Section
      2.1(b), and other than (i) with respect to TCI Group Member such of the
      foregoing as do not change the beneficial ownership interest of the
      Company in such TCI Group Member and (ii) with respect to the Company, any
      such merger, consolidation, restructuring, recapitalization or other
      reorganization that is used to effect an acquisition permitted pursuant to
      Section 7.1(f) and which does not result in a change of control of the
      Company or change the Shares into a different number or kind of
      securities);

            (f) make any acquisition, by means of merger, consolidation or
      otherwise (other than any acquisition by any Liberty Media Member or any
      TCI Ventures Member to the extent permitted under Section 7.18), of (i)
      any direct or indirect ownership interest in or assets comprising any
      business enterprise or operation or (ii) except in the ordinary course and
      consistent with past practice, any other assets; provided, however, that
      the Company may make such acquisitions for cash in an amount not to exceed
      $10 million in the case of any single acquisition or $50 million for all
      such acquisitions in the aggregate during any 12-month period; provided
      further that such acquisitions do not and would not prevent or materially
      delay the consummation of the Merger; and provided further that the

      and developing the basis on which to seek Parent's consent, so long as the
      Company does not submit any formal proposal or indication of interest with
      respect to such an acquisition to such acquisition target, or make any
      binding commitments with 

                                       52
<PAGE>

      respect to such potential acquisition, without obtaining Parent's consent;
      and provided further that in the event the Company is offered an
      opportunity under which it is required either to acquire or dispose of
      certain of its cable television system and related assets or related
      investments prior to the Effective Time and the taking of such action
      requires Parent's consent hereunder, Parent will not withhold its consent
      unreasonably;
     
            (g) (i) dispose of any controlling interest in any material business
      enterprise or operation of the TCI Group, (ii) make any other disposition
      of any other direct or indirect ownership interest in or assets comprising

      assets, in the ordinary course and consistent with past practice), or
      (iii) except in the ordinary course and consistent with past practice,
      dispose of any other assets of the TCI Group;

            (h) adopt any amendments to the Company Charter or the By-Laws of

      the Company may incur additional indebtedness after the date hereof, under
      existing credit facilities (or any renewals thereof), resulting in
      aggregate net proceeds to the Company from such additional indebtedness
      not exceeding $50 million, (B) the Company may refinance outstanding
      indebtedness (including indebtedness incurred pursuant to this Section
      7.1), without increase in the amount thereof, so long as the terms thereof

      than one year or such debt is prepayable without penalty, and (C) any
      Subsidiary of the Company that is not a member of the TCI Group shall be

            (k) enter into any agreement or exercise any discretion providing
      for acceleration of payment or performance as a result of a change of
      control of the Company or its Subsidiaries; provided that this paragraph

      or in the aggregate, to TCI Group;

            (n) settle or compromise any material litigation with respect to TCI
      Group or waive, release or assign any material rights or claims with

            (q) authorize, recommend or propose (other than to Parent), or
      announce an intention to do any of the foregoing, or enter into any

            7.2. Other Transactions. (a) The Company shall not, nor shall it
permit any of its Subsidiaries to, nor shall it authorize or permit any officer,
director or employee or any investment banker, attorney, accountant, agent or
other advisor or representative of the Company or any of its respective
Subsidiaries to, (i) solicit, initiate or knowingly encourage the submission of
any Takeover Proposal, (ii) enter into any agreement with respect to a Takeover
Proposal or (iii) participate in any discussions or negotiations regarding, or
furnish to any Person any information with respect to, or take any other action
to facilitate any inquiries or the making of any proposal that constitutes, or
may reasonably be expected to lead to, any Takeover Proposal; provided, however,
that to the extent required by the fiduciary obligations of the Board of
Directors of the Company, as determined in good faith by a majority of the
members thereof (after receipt of advice from Richards, Layton & Finger, outside
legal counsel to the Board of Directors), the Company may, in response to
unsolicited requests therefor, participate in discussions or negotiations with,
or furnish information pursuant to a confidentiality agreement no less favorable
to such party than the Confidentiality Agreement to, any Person who indicates a
willingness to make a Superior Proposal. For all purposes of this Agreement,
"Takeover Proposal" means any proposal for a merger, consolidation, share
exchange, business combination or other similar transaction involving the
Company or any of its Significant Subsidiaries or any proposal or offer to
acquire, directly or indirectly, an equity interest in, any voting securities
of, or a substantial portion of the assets of, the Company or any of its
Significant Subsidiaries, other than the transactions contemplated by this
Agreement and other than any transaction involving solely Liberty Media Members
or TCI Ventures Members which would not prevent or materially delay consummation
of the Merger. The Company immediately shall cease and cause to be terminated
all existing discussions or negotiations with any Persons conducted heretofore
with respect to, or that could reasonably be expected to lead to, any Takeover
Proposal. As used herein, a "Significant Subsidiary" means any Subsidiary that
would constitute a "significant subsidiary" within the meaning of Rule 1-02 of
Regulation S-X of the SEC.

      (b) Neither the Board of Directors of the Company nor any committee
thereof shall (i) withdraw or modify, or propose to withdraw or modify, in a
manner adverse to Parent, the approval 

                                       55
<PAGE>

or recommendation by the Board of Directors of the Company or any such committee
of this Agreement or the Merger or (ii) approve or recommend, or propose to
approve or recommend, any Takeover Proposal. Notwithstanding the foregoing, (A)
the Board of Directors of the Company or any committee thereof, to the extent
required by its fiduciary obligations, as determined in good faith by a majority
of the members thereof (after receipt of advice from Richards, Layton & Finger,
outside legal counsel to the Board of Directors), may approve or recommend a
Superior Proposal (and, in connection therewith, withdraw or modify its approval
or recommendation of this Agreement or the Merger) and (B) nothing contained in
this Agreement shall prevent the Board of Directors of Parent or the Company
from complying with Rule 14d-9 and Rule 14e-2 promulgated under the Exchange Act
with regard to a Takeover Proposal. For all purposes of this Agreement,
"Superior Proposal" means a bona fide written proposal made by a third party to
acquire the Company pursuant to a tender or exchange offer, a merger, a share
exchange, a sale of all or substantially all its assets or otherwise on terms
which a majority of the members of the Board of Directors of the Company
determines in good faith (taking into account the advice of independent
financial advisors) to be more favorable to the Company and its stockholders
than the Merger (and any revised proposal made by Parent) and for which
financing, to the extent required, is then fully committed or reasonably
determined to be available by the Board of Directors of the Company.

            7.3. Stockholder Approval. (a) Parent and the Company each shall
call its respective Stockholders Meeting to be held as promptly as practicable
for the purpose of voting upon, in the case of Parent, the Parent Charter
Amendment and the issuance of Parent Common Shares and Parent Liberty Tracking
Shares in connection with the Merger and, in the case of the Company, this
Agreement and the transactions contemplated hereby. Except as otherwise required
by the fiduciary duties of its Board of Directors (as determined in good faith
by such Board following the receipt of advice of its outside legal counsel to
such effect), (i)(A) the Company will, through the Board of Directors (based on
the recommendation of its Special Committee), recommend to its stockholders the
approval and adoption of this Agreement and the Merger, and (B) Parent will,
through its Board of Directors, recommend to its stockholders the approval of
the Parent Charter Amendment and the approval of the issuance of the Parent
Common Shares and Parent Liberty Tracking Shares in connection with the Merger,
and (ii) each of the Company and Parent will use their respective best efforts
to obtain the foregoing approval of their respective stockholders. Parent and
the Company shall coordinate and cooperate with respect to the timing of the
Stockholders Meetings and shall use their respective reasonable best efforts to
hold the Stockholders Meeting on the same day as soon as practicable 

                                       56
<PAGE>

after the date on which the Registration Statement becomes effective.

            (b) Notwithstanding the provisions of Section 7.3(a), after the
adoption of this Agreement by the stockholders of the Company, without the
affirmative approval, by vote or written consent, of the holders of Shares
representing a majority of the votes that may be cast by the holders of all then
outstanding Shares, the Company will not (i) enter into any amendment to this
Agreement that would alter or change any of the terms and conditions of this
Agreement if such alteration or change would adversely affect the holders of
Shares, or (ii) waive any condition set forth in Section 8.1 or Section 8.3 if
such waiver would materially adversely affect the holders of Shares.

            (c) Parent, as the sole stockholder of Merger Sub, hereby consents
to the adoption of this Agreement by Merger Sub and agrees that such consent
shall be treated for all purposes as a vote duly adopted at a meeting of the
stockholders of Merger Sub held for this purpose.

            7.4. Registration Statement and Proxy Statement. (a) As promptly as
practicable after the date of this Agreement, Parent and the Company shall
prepare and file with the SEC a preliminary joint proxy statement in form and
substance reasonably satisfactory to each of Parent and the Company and Parent
shall prepare and file with the SEC a registration statement on Form S-4 (the
"Registration Statement"), in which the joint proxy statement will be included
as part of a prospectus, in connection with the registration under the
Securities Act of the Parent Common Shares and Parent Liberty Tracking Shares
issuable upon conversion of the Shares (and any securities convertible into or
exchangeable for Shares) and the other transactions contemplated hereby. Each of
Parent and the Company shall use its reasonable best efforts to respond to any
comments of the SEC, to have the Registration Statement to be declared effective
as promptly as practicable after such filing and to cause the Proxy Statement
approved by the SEC to be mailed to the Company's stockholders at the earliest
practicable time. The Company and Parent will notify the other party promptly of
the receipt of any comments from the SEC or its staff and of any request by the
SEC or its staff or any other governmental officials for amendments or
supplements to the Registration Statement, the Proxy 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 Registration Statement, the Proxy Statement, the
Restructuring, 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 

                                       57
<PAGE>

applicable requirements of law. Whenever any event occurs which is required to
be set forth in an amendment or supplement to the Proxy Statement, the
Registration Statement or any other filing, Parent or the Company, as the case
may be, shall promptly inform the other party of such occurrence 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. The
Company and Parent each shall promptly provide the other (or its counsel) copies
of all filings made by it with any Governmental Body in connection with this
Agreement and the transactions contemplated hereby. Each party hereto agrees to
cooperate reasonably with each other party in connection with the preparation
and filing of the Registration Statement, including providing information to the
other party with respect to itself as may be reasonably required in connection
therewith.

            (b) The Proxy Statement shall include the recommendation of the
Board of Directors of the Company in favor of approval and adoption of this
Agreement and the Merger except to the extent the Board of Directors of the
Company shall have withdrawn or modified its approval or recommendation of this
Agreement or the Merger as permitted by Section 7.2(b) or 7.3(a), and the
recommendation of the Board of Directors of Parent in favor of approval of the
issuance of Parent Shares in the Merger and the Parent Charter Amendment, except
to the extent the Board of Directors of Parent shall have withdrawn or modified
its approval or recommendation of the issuance of Parent Shares in the Merger or
the Parent Charter Amendment as permitted by Section 7.3(a). The Company shall
use its reasonable best effort to cause the Proxy Statement to be mailed to its
stockholders, and Parent shall use its reasonable best efforts to cause the
Proxy Statement to be mailed to its stockholders, in each case as promptly as
practicable after the Registration Statement becomes effective.

            7.5. Reasonable Efforts. (a) Subject to Section 7.5(c), the Company
and Parent shall, and shall use all reasonable efforts to cause their respective
Subsidiaries, as applicable, to: (i) promptly make all filings and seek to
obtain all Authorizations required under all applicable Laws with respect to the
Merger and the other transactions contemplated hereby and will reasonably
consult and cooperate with each other with respect thereto; (ii) not take any
action (including effecting or agreeing to effect or announcing an intention or
proposal to effect, any acquisition, business combination or other transaction
except as set forth in the Parent Disclosure Statement or the Company Disclosure
Statement, as the case may be) which would impair the ability of the parties to
consummate the Merger (regardless of whether such action would otherwise be
permitted or not prohibited hereunder); and (iii) use all reasonable efforts to
promptly (x) take, or cause to be taken, all other actions and (y) do, or cause
to be done, all other 

                                       58
<PAGE>

things reasonably necessary, proper or appropriate to satisfy the conditions set
forth in Article VIII (unless waived) and to consummate and make effective the
transactions contemplated by this Agreement on the terms and conditions set
forth herein (including seeking to remove promptly any injunction or other legal
barrier that may prevent such consummation). Each party shall promptly notify
the other party of any communication to that party from any Governmental Body in
connection with any required filing with, or approval or review by, such
Governmental Body in connection with the Merger and permit the other party to
review in advance any proposed communication to any Governmental Body in such
connection to the extent permitted by applicable law. Notwithstanding the
foregoing, in connection with any filing or submission required or action to be
taken by either the Company or Parent or any of their respective Subsidiaries to
effect the Merger and to consummate the other transactions contemplated hereby,
(A) neither the Company nor any of its Subsidiaries shall, without Parent's
prior written consent, commit to any divestiture or hold separate or similar
transaction with respect to any asset or business of TCI Group, and each of the
Company and the TCI Group Members shall commit to, and shall use reasonable
efforts to effect, such thereof (which commitments may, at the Company's option,
be conditioned upon and effective as of the Effective Time) as Parent shall
reasonably request, and (B) neither Parent nor any of its Subsidiaries shall be
required to divest or hold separate or otherwise take (or refrain from taking)
or commit to take (or refrain from taking) any action that limits its freedom of
action with respect to, or its ability to retain, the Company or any of its
Subsidiaries or any material portion of the assets of the Company and its
Subsidiaries, or any of the business, product lines or assets of Parent or any
of its Subsidiaries, if any of the foregoing, individually or in the aggregate,
would have a Material Adverse Effect on the Company or on the TCI Group (or an
effect on Parent and its Subsidiaries that, were such effect applied to the
Company and its Subsidiaries, would constitute a Material Adverse Effect on the
Company or on the TCI Group).

            (b) In addition to the foregoing, the Company agrees that, in
connection with obtaining any Authorization required in connection with the
Merger and the transactions contemplated hereby, the Company will and will cause
its Subsidiaries (i) to commit to the divestiture by the Company and its
Subsidiaries of their entire interest in the Spectrum PCS Investment, and (ii)
following stockholder approval of the Parent Charter Amendment and the issuance
of Parent Shares in the Merger, (x) to place such interest in a trust or other
arrangement acceptable to the applicable Governmental Bodies pending such
divestiture, and (y) otherwise to comply with such requirements in connection
with such divestiture as may be imposed by the applicable Governmental Bodies.

                                       59
<PAGE>

            (c) Nothing in this Agreement shall prevent or restrict Parent and
its Subsidiaries from engaging in any merger, acquisition, business combination
or other transaction (whether or not Parent is the surviving corporation);
provided that such merger, acquisition, business combination or other
transaction would not (i) prevent, or delay beyond September 30, 1999, the
ability of Parent to consummate the Merger or (ii) cause the Merger to fail to
qualify as a tax-free reorganization; and provided, further, that the parties
will not delay the Closing in order to obtain any Authorizations to close
another subsequently announced transaction, or until such other Authorizations
are obtained.

            7.6. Access to Information. Subject to currently existing
contractual and legal restrictions applicable to the Company (which the Company
represents and warrants are not material with respect to TCI Group), and upon
reasonable notice, the Company shall (and shall cause each TCI Group Member to)
afford to officers, employees, counsel, accountants and other authorized
representatives of Parent ("Parent Representatives") reasonable access, during
normal business hours throughout the period prior to the Effective Time, to its
properties, books and records (including, subject to execution of appropriate
access letters, the work papers of independent accountants), such access not to
unreasonably interfere with the Company's business or operations, and, during
such period, shall (and shall cause each of the TCI Group Members to) furnish
promptly to such Parent Representatives all information concerning its business,
properties and personnel as may reasonably be requested, provided that no
investigation pursuant to this Section 7.6 shall affect or be deemed to modify
any of the respective representations or warranties made by the Company. Subject
to currently existing contractual and legal restrictions applicable to Parent
(which Parent represents and warrants are not material), and upon reasonable
notice, Parent shall (and shall cause its Significant Subsidiaries to) furnish
to to officers, employees, counsel, accountants and other authorized
representatives of the Company ("Company Representatives") such information
concerning its business, properties and personnel as may reasonably be
requested, provided that no investigation pursuant to this Section 7.6 shall
affect or be deemed to modify any of the respective representations or
warranties made by Parent. Each of Parent and the Company agrees that it will
not, and will cause the Parent Representatives or Company Representatives, as
the case may be, not to, use any information obtained pursuant to this Section
7.6 for any purpose unrelated to the consummation of the transactions
contemplated by this Agreement. All information obtained pursuant to this
Section 7.6 shall be subject to the Confidentiality Agreement, which shall
remain in full force and effect until consummation of the Merger or, if the
Merger is not consummated, for the period specified therein; provided, however,
that neither Parent nor the Company shall be precluded 

                                       60
<PAGE>

from making any disclosure which it deems required by law in connection with the
Merger. All requests for access to the Company and the TCI Group Members
pursuant to this Section 7.6 shall be made through the representatives of the
Company named in Section 7.6 of the Company Disclosure Statement, and all
requests for information to Parent and its Significant Subsidiaries pursuant to
this Section 7.6 shall be made through the representatives of Parent named in
Section 7.6 of the Parent Disclosure Statement.

            7.7. Indemnification of Directors and Officers. (a) From and after
the Effective Time, Parent and the Surviving Corporation shall jointly and
severally indemnify, defend and hold harmless the present and former officers,
directors and employees of the Company and any of its Subsidiaries, and any
Person who is or was serving at the request of the Company as an officer,
director or employee or agent of another Person, against all losses, expenses,
claims, damages or liabilities arising out of actions or omissions occurring on
or prior to the Effective Time (including the transactions contemplated by this
Agreement) to the fullest extent permitted under applicable Law (and shall also,
subject to Section 7.7(b), advance expenses as incurred to the fullest extent
permitted under applicable Law, provided that the Person to whom expenses are
advanced provides an undertaking to repay such advances if it is ultimately
determined that such Person is not entitled to indemnification); provided,
however, that such indemnification shall be provided only to the extent any
directors' and officers' liability insurance policy of the Company or its
Subsidiaries does not provide coverage and actual payment thereunder with
respect to the matters that would otherwise be subject to indemnification
hereunder (it being understood that Parent or the Surviving Corporation shall,
subject to Section 7.7(b), advance expenses on a current basis as provided in
this paragraph (a) notwithstanding such insurance coverage to the extent that
payments thereunder have not yet been made, in which case Parent or the
Surviving Corporation, as the case may be, shall be entitled to repayment of
such advances from the proceeds of such insurance coverage); and provided,
further, that (subject to Parent not causing the Surviving Corporation to divest
the assets of the Parent Liberty Group) Parent's indemnification obligation will
not apply to any losses, expenses, claims, damages or liabilities arising out of
actions or omissions, whether occurring on, prior to or following the Effective
Time, that relate to the Liberty Media Group or the TCI Ventures Group
(including with respect to the Liberty Media Exchange Ratios or, if applicable,
the TCI Ventures Exchange Ratios, the Restructuring insofar as it relates to the
Liberty Media Group and the TCI Ventures Group, disclosures with respect to the
Liberty Media Group or the TCI Ventures Group, or any other decisions with
respect to the Liberty Media Group or the TCI Ventures Group); provided that the
foregoing shall not be deemed to affect the obligations of the Surviving

                                       61
<PAGE>

Corporation hereunder. Parent 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
present or former directors, officers, employees, fiduciaries and agents of the
Company or any of its Subsidiaries, and any Person who is or was serving at the
request of the Company as an officer, director or employee or agent of another
Person (collectively, the "Indemnified Parties") as provided in the Company
Charter or By-Laws or pursuant to other agreements, or certificates of
incorporation or by-laws or similar documents of any of the Company's
Subsidiaries, as in effect as of the date hereof, with respect to matters
occurring through the Effective Time, 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. The Surviving Corporation
shall maintain in effect for not less than six years after the Effective Time
the current policies of directors' and officers' liability insurance maintained
by the Company and the Company's Subsidiaries with respect to matters occurring
prior to the Effective Time; provided, however, that (i) the Surviving
Corporation may substitute therefor policies of at least the same coverage
containing terms and conditions which are no less advantageous to the
Indemnified Parties with an insurance company or companies, the claims paying
ability of which is substantially equivalent to the claims paying ability of the
insurance company or companies providing such insurance coverage for directors
and officers of Parent and (ii) the Surviving Corporation shall not be required
to pay an annual premium for such insurance in excess of three times the last
annual premium paid prior to the date hereof, but in such case shall purchase as
much coverage as possible for such amount.

            (b) In the event that any Claim relating hereto or to the
transactions contemplated by this Agreement is commenced, before the Effective
Time, the parties hereto agree to cooperate and use their respective reasonable
efforts to vigorously defend against and respond thereto. Any Indemnified Party
wishing to claim indemnification under paragraph (a) of Section 7.7, upon
learning of any such claim, action, suit, proceeding or investigation, shall
promptly notify Parent thereof, whereupon Parent or the Surviving Corporation
shall have the right, from and after the Effective Time, to assume and control
the defense thereof, and upon such assumption, the Surviving Corporation shall
not be liable to such Indemnified Parties for any legal expenses of other
counsel or any other expenses subsequently incurred by such Indemnified Parties
in connection with the defense thereof. Notwithstanding the foregoing, if
counsel for the Indemnified Parties advises that 

                                       62
<PAGE>

there are issues which raise conflicts of interest between Parent or the
Surviving Corporation and the Indemnified Parties, the Indemnified Parties may
retain separate counsel and the Surviving Corporation will pay all reasonable
fees and expenses of such counsel; provided that the Surviving Corporation will
not be obligated pursuant to this sentence to pay for more than one firm of
counsel for all Indemnified Parties in any jurisdiction. The Surviving
Corporation shall not be liable for any settlement effected without its prior
written consent.

            (c) This Section 7.7 is intended to benefit the Indemnified Parties
and shall be binding on all successors and assigns of Parent, Merger Sub and the
Surviving Corporation.

            7.8. Registration and Listing of Parent Common Shares. (a) Parent
will use all reasonable efforts to register the Parent Common Shares and Parent
Liberty Tracking Shares to be issued pursuant to this Agreement, and upon
exercise of stock options granted to employees of the Company and its
Subsidiaries (or upon conversion of any convertible or exchangeable securities),
under the applicable provisions of the Securities Act and, if required, under
any applicable state securities laws.

            (b) Parent will use all reasonable efforts to cause the Parent
Common Shares and Parent Liberty Tracking Shares to be issued pursuant to this
Agreement and upon exercise of stock options granted to employees of the Company
and its Subsidiaries (or upon conversion of any convertible or exchangeable
securities), to be listed for trading on the NYSE or, in the case of the Parent
Liberty Tracking Shares, at Parent's option, on the National Market System of
NASDAQ.

            7.9. Affiliates of Parent and the Company. Concurrently with the
execution of this Agreement, each of the directors of the Company has executed
an agreement to the effect set forth in this Section 7.9. Prior to the Effective
Time, the Company shall deliver to Parent a letter identifying all other Persons
who, to the Company's knowledge, at the time of the Company Stockholders Meeting
or at the Effective Time, may be deemed to be "affiliates" of the Company for
purposes of Rule 145 under the Securities Act or who may otherwise be deemed to
be Affiliates of the Company (the "Rule 145 Affiliates"). The Company shall use
all reasonable efforts to cause each Person who is identified as a Rule 145
Affiliate in such list to deliver to Parent on or prior to the 30th day prior to
the Effective Time, a written agreement, in the form attached hereto as Exhibit
B, that such Rule 145 Affiliate will not sell, pledge, transfer or otherwise
dispose of any Parent Common Shares or Parent Liberty Tracking Shares issued to
such Rule 145 Affiliate pursuant to the Merger, except pursuant to an effective
registration statement or in compliance with Rule 145

                                       63
<PAGE>

under the Securities Act or an exemption from the registration requirements of
the Securities Act.

            7.10. Tax Matters. Each of the parties shall use all reasonable
efforts to cause the Merger to constitute a tax-free "reorganization" under
Section 368(a) of the Code. None of the parties will knowingly take any action,
and none of the parties will permit any of its Subsidiaries or Affiliates
knowingly to take any action, that would cause the Merger to fail to qualify as
a tax-free reorganization under Section 368(a) of the Code. Each of the parties
shall use all reasonable efforts to permit Wachtell, Lipton, Rosen & Katz and
Baker & Botts, L.L.P. to issue their opinions provided in Sections 8.2(d) and
8.3(d), respectively. Each party agrees to report the Merger on all tax returns
and other filings as a tax-free reorganization under Section 368(a) of the Code.
Except as otherwise provided herein, without the prior written consent of Parent
or unless the Liberty/Ventures Group agrees to assume the tax burden thereof,
the Company shall not (and shall not permit any Subsidiary to) take any action
that would cause a material acceleration of income under any "deferred
intercompany transaction" or "intercompany transaction" that is disclosed in
Part 2 of Section 5.10(b) of the Company Disclosure Statement.

            7.11. New York Real Property Transfer Tax. Any liability arising out
of New York State and/or New York City Real Property Transfer Taxes, with
respect to interests in real property owned, directly or indirectly, by the
Company immediately prior to the Merger, if applicable and due with respect to
the Merger, shall be borne by the Surviving Corporation and expressly shall not
be a liability of the stockholders of the Company.

            7.12. Employee Matters. (a) From and after the Effective Time,
Parent 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 TCI Group set forth in Section 7.12(a) of the
Company Disclosure Statement (the "Executive Agreements") and all the Employee
Plans and Benefit Arrangements relating to TCI Group; provided, however, that
nothing herein shall preclude any change in any Executive Agreement, Employee
Plan or Benefit Arrangement effective on a prospective basis that is permitted
pursuant to the terms of the applicable Employee Plan or Benefit Arrangement.
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 TCI Group, Parent shall assume the obligations of the
Company under the Employee Plans and Benefit Arrangements 

                                       64
<PAGE>

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 Parent 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 Parent. With respect to
any plans established by Parent, to the extent a Company Employee becomes
eligible to participate in any such plans, Parent shall grant to such Company
Employee from and 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 Employee Plans and Benefit Arrangements) prior to the
Effective Time for eligibility to participate, benefit accrual and vesting
purposes (except that no such credit shall be required for (i) benefit accrual
purposes under defined benefit pension plans, or the schedule of benefits under
Parent's severance pay and short-term disability plans and programs, (ii)
eligibility to receive post-retirement ancillary benefits (consisting at this
time of medical, dental, death and telephone concession benefits) or (iii)
calculating Parent service for purposes of "bridging" prior Parent service under
Parent benefit plans). To the extent Parent benefit plans provide medical or
dental welfare benefits, such plans shall waive any preexisting conditions and
actively at-work exclusions with respect to Company Employees (but only to the
extent such Company Employees were provided coverage under the Employee Plans
and Benefit Arrangements) and shall provide that any expenses incurred on or
before the Effective Time in the applicable plan year by or on behalf of any
Company Employees shall be taken into account under the Parent benefit plans for
the purposes of satisfying applicable deductible, co-insurance and maximum
out-of-pocket provisions for such Company Employees.

            (b) The Company may amend and/or take action with respect to its
1996 Stock Incentive Plan prior to the Effective Time to provide that upon a
termination of employment by a Company Employee with good reason or by the
Company without cause (in each case as defined in Schedule 7.12(b) attached
hereto) following the Effective Time, that options, stock appreciation rights or
other awards granted under such plan 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.

            (c) Parent 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.

                                       65
<PAGE>

            (d) For purposes of this Section 7.12, the term "Company Employees"
shall mean all individuals employed by the TCI Group (including those on
lay-off, disability or leave of absence, paid or unpaid) immediately prior to
the Effective Time.

            (e) The Company may enter into excise tax protective agreements with
certain of its employees and consultants (including non-employee directors) in
substantially the form attached as Schedule 7.12(e); provided that the TCI Group
shall assume the obligations under such agreements solely for Company Employees,
and the obligations under such agreements for employees of the Liberty/Ventures
Group shall be assumed by the Liberty/Ventures Group.

            7.13. Tax Sharing Agreement. Concurrently with the Closing, the
parties shall enter into an amendment to the Tax Sharing Agreement consistent
with the transactions contemplated by this Agreement, with respect to taxable
periods (or portions thereof) beginning on or after the Effective Time, on the
terms set forth in Exhibit C hereto.

            7.14. Other Intercompany Agreements. The TCI Group, the Liberty
Media Group and the TCI Ventures Group will comply with the principles set forth
in Schedule 7.14 with respect to any agreements between any TCI Group Member, on
the one hand, and any Liberty Media Member or TCI Ventures Member, on the other
hand. At the Effective Time, the Company, on behalf of the TCI Group, and the
appropriate Subsidiary or Subsidiaries of the Company, on behalf of the Parent
Liberty Group, will enter into an agreement having the terms set forth in
Schedule 7.14.

            7.15. Parent Board of Directors. At the Effective Time, Parent will
expand the size of its Board of Directors by one and will appoint Dr. John C.
Malone (or, in the event Dr. Malone is unable to serve, such other person as may
be designated by the Company and reasonably satisfactory to Parent) to the
Parent Board of Directors. From the Effective Time until the third anniversary
thereof, Parent will nominate Dr. Malone (or such other person) for reelection
to the Parent Board of Directors at each subsequent annual or special meeting of
the stockholders of Parent at which Dr. Malone's (or such other person's) term
is to expire. Thereafter (and during such period to the extent Dr. Malone or
such other person is unable to serve as a director), so long as any Parent
Liberty Tracking Shares remain outstanding, Parent will nominate and recommend
the election to the Parent Board of Directors a person (who may be Dr. Malone)
who, in the Parent Board of Directors' reasonable judgment, by virtue of his or
her background and experience, will understand and reflect issues of concern to
the Parent Liberty Group and the holders of Parent Liberty Tracking Shares.

                                       66
<PAGE>

            7.16. Parent Charter Amendment, Bylaw Amendment and Policy
Statement. The Board of Directors of Parent has approved the Parent Charter
Amendment in the form attached hereto as Exhibit A which amendment, subject to
the approval of the holders of a majority of the Parent Common Shares
outstanding at the special meeting of stockholders referred to in Section 7.3
and the filing thereof with the Secretary of State of New York, will become
effective immediately prior to the Effective Time. The Board of Directors has
also approved the amendment to Parent's bylaws, and the policy statement with
respect to Parent Liberty Tracking Shares, in the form attached hereto as
Exhibit D, each of which will become effective as of the Effective Time.

            7.17. Intercompany Transactions. Except as otherwise expressly
provided by the Restructuring, in the event that after the date hereof and prior
to the Effective Time, the Company or any of its Subsidiaries engages in any
action or transaction contemplated by clause (i) or (ii) of Section 7.1(p), the
applicable entities shall establish a commercially reasonable arms' length
intercompany loan or other non-equity based account to reflect such
transactions.

            7.18. Certain Inter-Group Relationships. From and including the date
hereof to the Effective Time, the Company will and will cause its Subsidiaries
to comply with the provisions set forth in Schedule 7.18. At the Effective Time,

      behalf of the Company pursuant to this Agreement, to the extent

      the case may be, only as of the specified date).

            (b) Performance. The Company shall have performed or complied in all
      material respects with all agreements and conditions contained herein
      required to be performed or complied with by it prior to or at the time of

            (d) Tax Opinion. Parent shall have received an opinion of Wachtell,

<PAGE>
      
      Adverse Effect on the Company (or an effect on Parent and its Subsidiaries
      that, were such effect applied to the Company and its Subsidiaries, would
      constitute a Material Adverse Effect on the Company), except for such
      Authorizations the failure of which to have been made or obtained does not
      and would not, individually or in the aggregate, have a Material Adverse
      Effect on the Company (or an effect on Parent and its Subsidiaries that,
      were such effect applied to the Company and its Subsidiaries, would
      constitute a Material Adverse Effect on the Company).

      receive and rely upon representations contained in certificates of Parent

contained in Section 7.7 of this Agreement.

proceeding arising in connection with this Agreement, and agrees that any such

objection based on forum non conveniens or any other objection to venue
therein); provided, however, that such consent to jurisdiction is solely for the
purpose referred to in this Section 10.10 and shall not be deemed to be a
general submission to the jurisdiction of said courts or in the State of

waive any right to a trial by jury in connection with any such action, suit or
proceeding.

                              AT&T AND TCI TO MERGE

    AT&T TO CREATE SEPARATELY TRADED UNIT TO PROVIDE CONSUMER COMMUNICATIONS
                           AND ENTERTAINMENT SERVICES

               AT&T'S SECOND QUARTER EARNINGS TO EXCEED ESTIMATES

FOR RELEASE WEDNESDAY, JUNE 24, 1998

         NEW YORK -- AT&T announced today that it has signed a definitive merger
agreement with Tele-Communications, Inc. (TCI) for an all-stock transaction
valued at approximately $48 billion. Under the agreement, AT&T will issue 0.7757
shares of AT&T common stock for each share of TCI Group Series A stock and
0.8533 shares of AT&T for each share of TCI Group Series B stock.

         Immediately following the merger, AT&T will combine its current
consumer long distance, wireless and Internet services units with TCI's cable,
telecommunications, and high-speed Internet businesses to create a new
subsidiary - AT&T Consumer Services. The company will trade as a "letter" or
"tracking stock" on the New York Stock Exchange and have a significant public
ownership. AT&T will also issue separate tracking stock to holders of TCI's
programming arm, Liberty Media Group, to continue the holders' interests in the
assets now represented by those shares.

         Separately, AT&T announced that its second quarter earnings would
exceed analyst estimates of 80 cents to 82 cents per share by 8 cents to 10
cents due to earlier

                                     -more-

and better than expected benefits from its on-going cost reduction efforts. The
company anticipates 1998 earnings of $3.35 to $3.45 per share, adjusted for the
effects of the company's pending merger with TCG.

AT&T Consumer Services

         AT&T Consumer Services will provide the broadest set of consumer
communications services -- including local, long distance, wireless and
international communications, cable television, dial-up and high-speed Internet
access services -- all under the AT&T brand name.

         AT&T Consumer Services will own and operate the nation's most
extensive, broadband local network platform. Following the merger, the new unit
intends to significantly accelerate the upgrading of its cable infrastructure,
enabling it to begin providing digital telephony and data services to consumers
by the end of 1999, in addition to digital video services.

         "Today we are beginning to answer a big part of the question about how
we will provide local service to U.S. consumers," said C. Michael Armstrong,
chairman and CEO of AT&T.

         "We are merging with TCI not only for what it is but for what we can
become together," Armstrong explained. "Through its own systems and in
partnership with affiliates, AT&T Consumer Services will bring to people's homes
the first fully integrated package of communications, electronic commerce and
video entertainment services. And it will do it with the quality and reliability
that people have come to expect from AT&T."

         "This merger is a tremendous growth opportunity for TCI's shareowners
and employees," said John C. Malone, chairman and CEO of TCI. "As TCI continues
the large-scale deployment of advanced digital set-top devices, AT&T's
extraordinary brand and resources are ideal complements to TCI's broadband cable
distribution and operations. AT&T Consumer Services will offer consumers a wide
variety of entertainment, information and communications products, which
thoughtfully address personal tastes, needs, choice and convenience."

         John D. Zeglis, currently president of AT&T, will be chairman and CEO
of AT&T Consumer Services and will remain on the AT&T Board of Directors. Leo J.
Hindery, Jr., currently president of TCI, will be the new unit's president and
chief operating officer. Malone has agreed to become a member of the AT&T Board
of Directors.

         AT&T Consumer Services will provide its services to consumers through a
combination of its own broadband networks and services it will procure from
others, including AT&T. The new unit will include all of the cable television
systems AT&T is acquiring in the merger with TCI, as well as AT&T's fixed
wireless technology and related spectrum rights covering more than 90 percent of
the nation. When the merger and pending TCI cable system transactions are
complete, AT&T Consumer Services' wholly owned and affiliated cable systems will
pass 33 million homes.

         In addition to these physical assets, AT&T Consumer Services will also
include all elements of AT&T's existing consumer businesses, except network
operations that it will procure from its parent. AT&T's consumer businesses
include the nation's leading long distance services, with annual revenues of
approximately $23 billion, and the most broadly available wireless services,
with annual revenues greater than $3 billion.

         AT&T's consumer businesses include WorldNet, one of the industry's
leading dial-up Internet access services. Through the acquisition of TCI, AT&T
Consumer Services will also hold a controlling interest in the @Home Network,
the leading provider of high-speed Internet access and content services. @Home
currently has affiliate agreements with TCI and several major cable companies
that collectively pass more than 50 million homes.

         On a pro forma basis, before considering synergies, the company
projects that AT&T Consumer Services could have 1999 revenue of approximately
$33 billion and earnings before interest, taxes, depreciation and amortization
(EBITDA) of approximately $7 billion to $7.5 billion. AT&T and TCI anticipate
their merger will result in increased revenue and lower costs, producing
synergies of approximately $2 billion per year beginning three years after the
merger closes. For example, the merger is expected to improve TCI's cable
service penetration and improve customer retention for AT&T's consumer long
distance service. It will also help reduce the charges AT&T pays to local
telephone companies to handle long distance calls and allow both companies to
reduce their respective customer care, billing and advertising expenses.

Business Communications and Wholesale Networking Services

AT&T itself will remain the world leader in business communications services and
become the leader in wholesale networking services. On a pro forma basis, the
company projects its 1999 revenues from those businesses could exceed $29
billion and its EBITDA could reach approximately $12 billion. AT&T will continue
to provide global communications, outsourcing and systems integration services
to more than 15 million businesses and institutions. It will own and operate the
world's most extensive and advanced communications network, the nation's largest
wireless infrastructure, and, following the pending acquisition of TCG, a local
access network reaching more than 250 cities from coast to coast.

         "AT&T is now better positioned for growth," said Armstrong. "When this
transaction is completed, AT&T will be the undisputed leader in three of the
fastest growing segments of the communications services industry consumer,
business and wholesale networking services."

         Neither AT&T nor TCI anticipates any significant downsizing to result
from the merger. Most AT&T and TCI employees will follow their jobs, and both
companies have established senior management teams to ensure a smooth
transition. In fact, both companies expect the merger and the creation of AT&T
Consumer Services to accelerate their growth, significantly enhancing career
opportunities for all employees involved.

         AT&T and TCI said that they expect the merger, which is contingent on
regulatory and other approvals, to be tax-free to their respective shareholders
and to close in the first half of 1999.
