                        THE RESTRUCTURING AND THE MERGER

                   2.1. The Restructuring. (a) Subject to the terms and
         conditions of this Agreement, prior to the Effective Time, and provided
         that all of the conditions set forth in Article VIII to be satisfied
         prior to the Closing have been satisfied or duly waived, the Company
         shall take the actions set forth in Schedule 2.1(a). By virtue of the
         transfers contemplated by Schedule 2.1(a), TCI Group will obtain
         ownership of, among other things, (i) 31,060,000 @Home Class A Shares

         whatsoever paid or distributed in respect thereof after the date of
         this Agreement, (ii) 1,011,528 shares of Class A common stock of TCG
         and 48,779,388 shares of Class B common stock of TCG (representing all

         consideration whatsoever paid or distributed in respect thereof or in
         exchange therefor after the date of this Agreement, and (iii) all of
         the assets of or outstanding equity interests in NDTC, together with
         any dividends, distributions or other consideration whatsoever paid or
         distributed in respect thereof after the date of this Agreement. The
         actions contemplated by Schedule 2.1(a) will be effected on a tax-free
         basis to the extent feasible, 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 direct or indirect TCI Group Subsidiaries owning
         TCI Group Shares to merge into the Company (or their respective parent
         corporations) or otherwise to liquidate so that such TCI Group Shares
         are not outstanding for federal income tax purposes at the Effective
         Time, provided that any such merger or liquidation is tax-free.

                   (c) At or prior to the Effective Time, to the extent the
         Board of Directors of the Company so determines, the Company may, but
         shall not be required to: (i) amend and restate the certificate of
         incorporation and bylaws of Liberty Media Corporation to be in
         substantially the form set forth in Schedule 2.1(c)(i), (ii) cause
         Liberty Media Corporation to enter into a Contribution Agreement in the
         form set forth in Schedule 2.1(c)(ii) with the other parties set forth
         in such agreement (the "Contribution Agreement"), and (iii) create the
         Liberty Group LLC pursuant to an LLC Agreement in the form set forth in
         Schedule 2.1(c)(iii). In the event the Company takes the foregoing
         actions, the rights and obligations of Liberty Media Corporation under
         the agreement contemplated by Section 7.18 shall be assignable to the
         Liberty Group LLC. In the event the Company causes Liberty Media
         Corporation to execute the Contribution Agreement, Parent will execute
         and deliver a letter at the Closing in the form attached as Schedule
         2.1(c)(iv).

                   (d) Subject to the terms and conditions of this Agreement,
         prior to the Effective Time, provided that all of the conditions set
         forth in Article 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 re-
         ferred to as the "Restructuring."

                   2.2. The Merger. Subject to the terms and conditions of this
         Agreement, at the Effective Time, Merger Sub shall be merged with and
         into the Company in accordance with the provisions of Section 251 of
         the DGCL and with the effect provided in Sections 259 and 261 of the
         DGCL. The separate corporate existence of Merger Sub shall thereupon
         cease and the Company shall be the Surviving Corporation and shall
         continue its corporate existence as a Subsidiary of Parent and shall
         continue to be governed by the laws of the State of Delaware. At the
         election of Parent, any direct Wholly Owned Subsidiary of Parent with
         respect to which the representation and warranty set forth in Section
         6.15 is true and correct may be substituted for Merger Sub as a
         constituent corporation in the Merger by an appropriate amendment to
         this Agreement complying with the provisions of the DGCL.

                   2.3. Effective Time. The Merger shall become effective on the
         date and at the time (the "Effective Time") that the Certificate of
         Merger shall have been accepted for filing by the Secretary of State of
         the State of Delaware (or such later date and time as may be specified
         in the Certificate of


                                       -14-

         Merger by mutual agreement of Parent, Merger Sub and the Company),
         which shall be on the Closing Date or as soon as practicable
         thereafter.

                   2.4. Closing. Subject to the fulfillment or waiver of the
         conditions set forth in Article VIII, the Closing shall take place (a)
         at the offices of Wachtell, Lipton, Rosen & Katz, 51 West 52nd Street,
         New York, New York, at 10:00 a.m. on the earliest practicable date (but
         no later than the fifth business day) following the satisfaction or
         waiver of the conditions set forth in Article VIII (other than those
         conditions to be satisfied or waived at the Closing) or (b) at such
         other place and/or time and/or on such other date as Parent, Merger Sub
         and the Company may agree.

                   3.2. The By-Laws. The By-Laws of the Company shall be amended

                       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

              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 "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-

              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.

                   (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.

                   (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

              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

              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

              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

                   (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

              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-

              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

              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 that, subject to applicable
              escheat law, it shall receive and hold all dividends or other
              distributions paid or distributed with respect to such Parent
              Common Shares or Parent Liberty Tracking Shares, as applicable,
              for the account of the Persons entitled thereto.

                   (c) Certificates surrendered for exchange by any Person
              constituting a Rule 145 Affiliate of the Company shall not be
              exchanged for certificates representing Parent Common Shares or
              Parent Liberty Tracking 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 be issued in the Merger. In lieu of any such fractional
         securities, each holder of TCI Group Shares who would otherwise have
         been entitled to a fraction of a 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-

         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>   32









         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>   33









         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>   34









         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>   35









         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 a
         Material Adverse Effect on the Company or on the TCI Group or (B)
         prevent or materially delay the consummation of the Merger.

                   5.5. Opinion of the Company's Financial Advisor. The Board of
         Directors of the Company has received the opinion, dated as of the date
         hereof, of Donaldson, Lufkin & Jenrette Securities Corporation to the
         effect that the Exchange Ratios are fair to the stockholders of the
         Company from a financial point of view.

                   5.6. Capital Stock. (a) The authorized capital stock of the
         Company consists of 3,602,375,096 shares, consisting of 3,550,000,000
         shares of common stock, par value $1.00 per share ("Company Common

         to the knowledge of the Company, threatened against the Company or any
         of its Subsidiaries (or any Employee Plan or Benefit Arrangement), or
         any property of the Company or any such Subsidiary (including
         Intellectual Property), before any arbitrator of any kind or in or
         before or by any Governmental Body, except actions, suits,

         would not, if adversely determined, (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.

                   5.8. Compliance with Other Instruments, Etc. Neither the

         stockholders as contemplated by Section 7.3, the execution, delivery
         and performance of this Agreement and the consummation of the

         conflict with, or constitute a default under, the charter, bylaws or
         other organizational documents of the Company (or any of its
         Subsidiaries). Except as set forth in Section 5.8 of the Company
         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 right or obligation under, any agreement, note,

         Subsidiaries to create) any mortgage, lien, charge, security interest
         or other encumbrance upon any of the properties or assets of the
         Company 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 the Company or on
         the TCI Group or (ii) prevent or materially delay the consummation of
         the Merger.

                   5.9.  Employee Benefit Plans.  (a)  The Company Dis-

                                       -34-

<PAGE>   40









         complete list of each material "employee benefit plan" (as defined in
         Section 3(3) of ERISA) of the Company and its Subsidiaries in which
         current or former employees, agents, directors, or independent
         contractors of the Company or its Subsidiaries ("Employees")
         participate or pursuant to which the Company or any of its Subsidiaries
         may have a liability with respect to Employees (each, an "Employee
         Plan"), and each other material plan, program, policy, contract or
         arrangement of the Company and its Subsidiaries providing for bonuses,
         pensions, deferred pay, stock or stock related awards, severance pay,
         salary continuation or similar benefits, hospitalization, medical,
         dental or disability benefits, life insurance or other employee
         benefits, or compensation to or for any Employees or any beneficiaries
         or dependents of any Employees (other than 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-

         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-

         (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

         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

         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

         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.

         accurate and complete listing, as of the date hereof, of (a) all
         contracts, leases, agreements or understandings, whether written or

         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. The Company has previously
         provided or made available to Parent true and complete copies of each
         of the foregoing agreements. Except as disclosed in the Company SEC
         Reports, there are no relationships or transactions of a type required
         to be disclosed in the Company SEC Reports pursuant to Item 404 of
         Regulation S-K promulgated under the Securities Act.

                   5.15. Brokers and Finders. Except for the fees and expenses
         payable to Donaldson, Lufkin & Jenrette Securities Corporation, which
         fees and expenses are reflected in its agreements with the Company,

         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

         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.

         Act.

         combined balance sheets (including the related notes) of each of the
         TCI Group, the Liberty Media Group and the TCI Ventures Group included

         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
         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. Except (i) as and to the extent disclosed or
         reserved against on the balance sheet of the TCI Group, the Liberty
         Media Group or the TCI Ventures Group as of December 31, 1997 included

         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.

                                       -41-

         and having terms and conditions that are no less favorable to TCI Group

                                   ARTICLE VI

             REPRESENTATIONS AND WARRANTIES OF PARENT AND MERGER SUB

                   Parent and Merger Sub each represents and warrants to the
         Company 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 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 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 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 Parent.

                   6.3. Agreement. Each of Parent and Merger Sub 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
         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 Section 7.3. This Agreement has been duly executed and delivered by
         a duly authorized officer of Parent and of Merger Sub and (assuming the
         due execution and delivery of this


                                       -43-

         Agreement by the Company) constitutes a valid and binding agreement of
         Parent and Merger Sub, enforceable against Parent and Merger Sub in
         accordance with its terms.

                   6.4. Permits; Compliance. Each of Parent and its Subsidiaries
         is in possession of all Permits from appropriate Governmental Bodies
         (including the 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 or in the aggregate, (x) have a Material
         Adverse Effect on Parent or (y) prevent or materially delay the
         consummation of the Merger. Neither Parent nor any of its Subsidiaries
         is in conflict with, or in default or violation of, (i) any Law
         applicable to Parent or any of its Subsidiaries or by which any
         property, asset or operation of Parent or any of its Subsidiaries is
         bound or affected or (ii) 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 Goldman Sachs & Co. and Credit Suisse First Boston
         Corporation to the effect that, as of such date, the Exchange Ratios,
         collectively, are fair to Parent from a financial point of view.

                   6.6. Capital Stock. As of the date hereof, the authorized
         capital stock of Parent consists of (a) 6,000,000,000 Parent Common
         Shares and (ii) 100,000,000 shares of preferred stock, $1.00 par value
         per share. All of the outstanding shares of capital stock of Parent are
         duly authorized, validly issued, fully paid and nonassessable, and no
         class of capital stock of Parent is entitled to preemptive rights. As
         of the close of business on April 30, 1998, 1,624,198,000 Parent Common
         Shares and no shares of Parent preferred stock were issued and
         outstanding. Except as disclosed in the Parent SEC Reports, all
         outstanding shares of capital stock of the Significant Subsidiaries (as
         defined for purposes of Regulation S-X under the Exchange Act) of
         Parent are owned by Parent or a direct or indirect Wholly Owned
         Subsidiary of Parent, free and clear of all liens, charges,
         encumbrances, claims and options

         were outstanding options to acquire no more than 69,000,000 Parent
         Common Shares.

                   6.7. Parent Shares. The Parent Common Shares and the Parent
         Liberty Tracking Shares to be issued pursuant to Article IV will, when
         issued, be duly authorized, validly issued, fully paid and
         nonassessable and no stockholder of Parent will have any preemptive
         right of subscription or purchase in respect thereof. The Parent Common
         Shares and the Parent Liberty Tracking Shares to be issued in the
         Merger will, when issued, be registered under the Securities Act 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 prior to the date hereof, there are, as of the date
         hereof, no actions, suits, investigations or proceedings (adjudicatory,
         rulemaking or otherwise) pending or, to the knowledge of Parent,
         threatened against Parent or any of its 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

         under, any agreement, note, bond, mortgage, indenture, contract, lease,
         Permit 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-

         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.

                   (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).

         previously delivered by the Company to Parent (the "Capital Spending
         Plan"), as required by any change in applicable Law, or as otherwise
         agreed by Parent in writing, during the period from the date of this
         Agreement to the Effective Time, (i) the Company will, and will cause
         each of the TCI Group Members to, conduct the TCI Group Business in the
         ordinary course of business consistent with past practice, and (ii) to

              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);

              Group Member not constituting an 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

              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 foregoing shall not prevent the Company from
              exploring on a preliminary basis and conducting diligence
              investigations (including having discussions with any potential
              acquisition target) with respect to any potential acquisition that
              would require Parent's consent hereunder, for the purpose of
              determining the desirability of such potential acquisition 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-

              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 a material business enterprise or
              operation of the TCI Group (except for the replacement or upgrade
              of assets, or disposition of unnecessary 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 or alter through merger, liquidation,

              constituting an inactive Subsidiary of the Company;

                   (i) incur any indebtedness for borrowed money or guarantee
              any indebtedness of any other Person or make any loans, advances

              (other than to the Company or any Wholly Owned Subsidiary of the
              Company), except that (A) 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 are no less favorable to the Company and the
              maturity thereof is no more 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 permitted to do any

                   (j) engage in the conduct of any business other than the
              Company's existing businesses (except that the Liberty Media Group
              and the TCI Ventures Group may engage in other businesses to the
              extent permitted pursuant to Section 7.18);

              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 (k) shall not restrict the Company's
              right to respond or take action in response to any such
              acceleration so long as such action is permitted under this
              Section 7.1;

              requiring in the aggregate the purchase of equipment, materials,

              the Liberty Media Group and the TCI Ventures Group, as permitted
              pursuant to Section 7.18), other than any such contracts,
              arrangements or understandings providing for capital spending of
              the Company or the TCI Group Members in accordance with the

              other transaction


                                       -54-

<PAGE>   60









              involving any TCI Group Member, on the one hand, and any
              Liberty Media Member or TCI Ventures Member, on the other
              hand;

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

                   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>   61









         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>   62









         after the date on which the Registration Statement becomes ef-
         fective.

                   (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>   63









         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>   64









         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.

                   (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-

         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-

         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>   68









         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

         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>   70









         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 medi-cal or dental welfare
         benefits, such plans shall waive any pre-existing 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.

                   (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.

         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.

              Lipton, Rosen & Katz may receive and rely upon representations
              contained in certificates of the Company, Parent, Merger Sub and
              others, in each case in form and substance reasonably acceptable
              to Wachtell, Lipton, Rosen & Katz.

              with the execution and delivery of this Agreement and the
              performance of the obligations hereunder shall have been made or
              obtained, without any limitation, restriction or condition that
              has or would 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

              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).

              Sub pursuant to this Agreement, to the extent qualified by
              materiality or Material Adverse Effect, shall have been true and,
              to the extent not qualified by materiality or Material Adverse
              Effect, shall have been true in all material respects, in each
              case when made and on and as of the Closing Date as though made on
              and as of the Closing Date (except for representations and
              warranties made as of a specified date, which need be true, or

              of Baker & Botts, L.L.P., dated the Effective Time, to the effect
              that (i) the Merger should be treated for federal income tax
              purposes as a reorganization within the meaning of Section 368(a)
              of the Code; (ii) each of Parent, Merger Sub and the Company
              should be a party to the reorganization within the meaning of
              Section 368(b) of the Code; (iii) no gain or loss should be

         this Agreement has been the cause of or resulted in the failure of the
         Merger to occur on or before such date, and provided, further, that in
         the event that the failure of the Merger to occur on or before March

         satisfied by such date), (b) any court of competent jurisdiction in the
         United States or Governmental Body in the United States shall have

         Merger or the Parent Charter Amendment as permitted by Section 7.3(a)
         or (b) Parent or Merger Sub breaches or fails in any material respect
         to perform or comply with its covenants and agreements contained herein
         or breaches its representations and warranties, in each case that is
         not curable, such that the conditions set forth in Sections 8.3(a) and

         Agreement between Parent and the Company and the other agreements
         expressly contemplated hereby) embodies the entire agreement and
         understanding between the parties relating to the subject matter hereof
         and supersedes all prior agreements and understandings relating to such

         by the parties hereto relating to such subject matter other than those
         expressly set forth in this Agreement (including the Company Disclosure

                   10.6. Specific Performance. The parties acknowledge that

         any right, power or remedy provided under this Agreement or otherwise
         available in respect hereof at law or in equity, or to insist upon
         compliance by any other party hereto with its obligations hereunder,
         and any custom or practice of the parties at variance with the terms
         hereof, shall not constitute a waiver by such party of its right to
         exercise any such or other right, power or remedy or to demand such
         compliance.

                   10.9. No Third Party Beneficiaries. This Agreement is not
         intended to be for the benefit of and shall not be enforceable by any
         Person or entity who or which is not a party hereto, except for the
         indemnification provisions contained in Section 7.7, which provisions
         may be enforced by any Indemnified Party referred to therein and except
         that the provisions of Section 7.3(b) may be enforced by holders of
         Shares. Notwithstanding anything to the contrary contained in this
         Agreement, the provisions of Section 7.7 of this Agreement may not be
         amended or altered in any manner with respect to any Indemnified Party
         without the written consent of such Indemnified Party. No assignment of
         this Agreement shall relieve Parent from its obligations to any
         Indemnified Party contained in Section 7.7 of this Agreement.

         brought only in such court (and waives any objection based on forum non

         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
         Delaware other than for such purpose. Parent, Merger Sub and the
         Company hereby waive any right to a trial by jury in connection with
         any such action, suit or proceeding.

                   10.11. Public Announcements. Parent and the Company will

         agreement unless required to do so by applicable Law or regulation. To
         the extent reasonably requested by either party, each party will
         thereafter consult with and provide reasonable cooperation to the other

         public documents describing the transactions contemplated by this
         Agreement.

                   10.12. Governing Law. This Agreement and all disputes
         hereunder shall be governed by and construed and enforced in accordance
         with the internal laws of the State of Delaware, without regard to
         principles of conflict of laws.

                   10.13. Name, Captions, Etc. The name assigned this Agreement
         and the section captions used herein are for convenience of reference
         only and shall not affect the interpretation or construction hereof.
         Unless otherwise specified, (a) the terms "hereof", "herein" and
         similar terms refer to this Agreement as a whole and (b) references
         herein to Articles or Sections refer to articles or sections of this

         deemed to be followed by the words "without limitation."

                   10.14. Counterparts. This Agreement may be executed in any
         number of counterparts, each of which shall be deemed to be an
         original, but all of which together shall constitute one instrument.

         than all, but together signed by all, the parties hereto.

                   10.15. Survival of Representations, Warranties, Covenants and
         Agreements. The respective representations and warranties of the
         parties contained herein or in any certificates or other documents

<PAGE>   83









         survive the execution and delivery of this Agreement, notwithstanding
         any investigation made or information obtained by the other parties,
         but shall terminate at the Effective Time. The respective covenants and
         agreements of the parties contained herein or in any other documents
         delivered prior to or at the Closing shall survive the execution and
         delivery of this Agreement and shall only terminate in accordance with
         their respective terms.

                   10.16. Severability. In case any provision in this Agreement
         shall be held invalid, illegal or unenforceable in a jurisdiction, such
         provision shall be modified or deleted, as to the jurisdiction
         involved, only to the extent necessary to render the same valid, legal
         and enforceable, and the validity, legality and enforceability of the
         remaining provisions hereof shall not in any way be affected or
         impaired thereby nor shall the validity, legality or enforceability of
         such provision be affected thereby in any other jurisdiction.

         this Agreement (i) relate to certain matters concerning the disclosures
         required and transactions contemplated by this Agreement, (ii) are
         qualified in their entirety by reference to specific provisions of this
         Agreement, (iii) are not intended to constitute and shall not be
         construed as indicating that such matter is required to be disclosed,
         nor shall such disclosure be construed as an admission that such
         information is material with respect to the Company or Parent, as the
         case may be, except to the extent required by this Agreement, and (iv)
         disclosure of the information contained in one section or part of the
         Company Disclosure Statement or the Parent Disclosure Statement shall
         be deemed as proper disclosure for all sections or parts of the Company
         Disclosure Statement or the Parent Disclosure Statement, as the case
         may be, only if appropriately cross-referenced or if the relevance
         thereof is reasonably apparent from the context in which it appears.

 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

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.

FOR IMMEDIATE RELEASE
JUNE 24, 1998
CONTACTS:         VIVIAN CARR, LIBERTY MEDIA GROUP, (303) 721-5406
                  LARAE MARSIK, TCI MEDIA RELATIONS, (303) 267-5273
                  LINDA DILL, TCI INVESTOR RELATIONS, (303) 267-5048


             LIBERTY MEDIA GROUP TO COMBINE WITH TCI VENTURES GROUP

 NEW ENTITY HEADED BY JOHN MALONE TO BE SEPARATELY TRADED TRACKING STOCK OF AT&T
                         UPON CLOSING OF AT&T/TCI MERGER


NEW YORK, NY/ENGLEWOOD, CO -- Tele-Communications, Inc. announced its intention
to combine Liberty Media Group (NASDAQ: LBYTA), its programming arm, and TCI
Ventures Group (NASDAQ: TCIVA), its technology investments unit. The proposed
combination is concurrent with, but not conditional upon, today's announcement
of the signing of a merger agreement between Tele-Communications, Inc. (TCI) and
AT&T (NYSE: T ). Under the terms of the consolidation, which is subject to
shareholder approval, each outstanding share of TCIVA or TCIVB stock will be
exchanged for .52 shares of LBTYA or LBTYB, as the case may be. John C. Malone,
TCI's Chairman and Chief Executive Officer, will serve as Chairman of the
consolidated group, which will be called Liberty Media Group, and Robert R.
Bennett, President and CEO of Liberty, will be President and CEO of the new
entity.

Upon closing of the AT&T/TCI merger, the shareholders of the new Liberty Media
Group will be issued separate tracking stock by AT&T in exchange for the shares
currently held. In addition, prior to the closing, Liberty's investment in At
Home Corporation (NASDAQ: ATHM), its investment in the National Digital
Television Center, and its ownership of Western Tele-Communications, Inc. will
be acquired by TCI Group for $2.5 billion cash in a tax-free transaction. The
AT&T shares which TCI Ventures Group will acquire upon closing of the Teleport
(NASDAQ: TCGI) transaction will also be acquired by TCI Group for approximately
$3.0 billion cash in a tax-free transaction. The new AT&T tracking stock will
track the remaining assets of the current Liberty and Ventures Groups together
with the approximately $5.5 billion of cash proceeds from the foregoing
transactions. Liberty will inherit TCI's net operating loss carryforward
existing at the closing of the AT&T/TCI merger; such carryforward is currently
approximately $1.7 billion and is subject to change prior to such closing.

"The new Liberty Media Group's exceptional programming and technology
investments, plus the substantial cash it will have, will help grow new
businesses, develop content and realize solid asset values for the benefit of
the stockholders of Liberty Media Group," said Mr. Malone. "I am very pleased to
work closely with Dob Bennett and to focus my attention on the wealth of
opportunities which exist."
