Item 5.   Other Events.
          ------------ 

          Bob Magness, one of the founders and principal stockholders of Tele-
Communications, Inc. ("TCI" or the "Company"), died on November 15, 1996.  His
death was preceded by the death of his first wife, Betsy Magness.  Following Bob
Magness' death, proceedings relating to probate of the Estate of Bob Magness
were commenced in the District Court for Arapahoe County, Colorado under the
caption In re Estate of Bob Magness, Case No. 96 PR 944 (the "Proceedings").
        ---------------------------                                         

          On June 16, 1997, certain transactions were entered into by, among
others, the Estate of Bob Magness (the "Estate"), affiliates of Merrill Lynch,
Pierce, Fenner & Smith Incorporated (collectively "Merrill"), affiliates of
Lehman Brothers (collectively "Lehman") and TCI, which involved, among other
things, (a) the Estate exchanging (with TCI) shares of TCI's Series B TCI Group
Common Stock ("Series B TCI Group Stock") it held for an equal number of newly
issued shares of TCI's Series A TCI Group Common Stock ("Series A TCI Group
Stock"); (b) the sale by the Estate of the shares of Series A TCI Group Stock
(together with other shares of such stock previously owned by the Estate) to
Merrill and Lehman; and (c) the execution of an equity swap agreement by which
TCI acquired certain rights to purchase Series A TCI Group Stock shares (and
shares of any other series that such shares may be exchanged for) from Merrill
and Lehman.  Those transactions are sometimes referred to as "the June 16 Stock
Transaction."  For further information regarding the June 16 Stock Transaction,
reference is made to Amendment No.2 to Schedule 13D statement of Dr. John C.
Malone in respect of TCI.

          In connection with the Proceedings, one or more of Gary Magness and
Kim Magness, Bob Magness' sons, Sharon Magness, Bob Magness' surviving second
wife and the original personal representatives of the Estate advanced various
claims, causes of action, demands, complaints and requests against one or more
of the others.  In addition, Kim Magness and Gary Magness, in a Complaint And
Request To Void Sale Of TCI Stock, And For Damages And Surcharge, filed in the
Proceedings on October 29, 1997 (the "Voiding Action") advanced various claims
relating to the June 16 Stock Transaction against TCI, Dr. John C. Malone, the
Chairman of the Board and Chief 

                                      -2-
<PAGE>
 
Executive Officer of TCI ("Malone") and the original personal representatives of
the Estate (the "Voiding Complaint").

          Pursuant to an agreement effective as of January 5, 1998 (the
"Settlement Agreement"), TCI, Gary Magness, Kim Magness, Sharon Magness, the
Estate, the Estate of Betsy Magness and Malone agreed to settle their respective
claims against each other relating to the Estate and the June 16 Stock
Transaction, in each case without any of those parties admitting any of the
claims or allegations against that party.

          Concurrently with execution of the Settlement Agreement, the Estate,
Kim Magness, Gary Magness, Sharon Magness, TCI, Malone and the original
executors of the Magness Estate entered into a Mutual Release And Settlement
Agreement (the "Mutual Release") with respect to certain of the claims relating
to the Estate.  In accordance with the terms of the Settlement Agreement, Gary
and Kim Magness were appointed as the personal representatives of the Estate,
replacing the two original personal representatives.

          On or about January 5, 1998, the Court in the Proceedings, in
accordance with the terms of the Settlement Agreement and the Mutual Release,
entered an order (i) voiding that portion of the June 16 Stock Transaction to
the extent of the sale by the Estate of 10,201,041 shares of Series A TCI Group
Stock and 5,833,253 Shares of TCI's Series A TCI Ventures Group Common Stock, to
Merrill and Lehman (the "Returned Shares"), (ii) approving that portion of the
June 16 Stock Transaction to the extent of the sale of 16,034,294 shares of
Series A TCI Group Stock (the "Sold Shares"), (iii) dismissing the Voiding
Complaint as to the original personal representatives of the Estate and (iv)
staying the Voiding Complaint as to TCI and Malone.  On or about February 6,
1998, also in accordance with the terms of the Settlement Agreement, the Court
in the Proceedings entered an order dismissing with prejudice the Voiding
Complaint as to TCI and Malone.  As a result, the June 16 Stock Transaction was
reversed as to the Returned Shares on or about February 9, 1998, but the sale of
the Sold Shares was unaffected and the agreements and other documents entered
into with regard to the June 16 Stock Transaction continue in effect for the
Sold Shares.

          As required by the Settlement Agreement, Malone and Leslie Malone, his
wife (the "Malone Group"), Gary and Kim Magness (individually and as trustees of
certain family trusts), the 

                                      -3-
<PAGE>
 
Estate and the Estate of Betsy Magness (the "Magness Group") and TCI entered
into a Stockholders' Agreement, dated as of February 9, 1998 (the "Stockholders
Agreement"). The Stockholders Agreement provides: (a) for the Magness Group to
designate a nominee for TCI's Board of Directors and Dr. Malone's agreement to
vote all High Vote Shares beneficially owned by him for such nominee; (b) for a
representative of the Malone Group and a representative of the Magness Group to
consult with each other as to the manner in which each group's High Vote Shares
are to be voted on all matters to be brought to a vote of the TCI's
stockholders; (c) that if a mutual agreement on how to vote cannot be reached,
Malone will vote the High Vote Shares owned by the Magness Group pursuant to an
irrevocable proxy; (d) for the Magness Group to participate, at its option, on a
proportionate basis with Malone in any acquisition of securities of TCI or
certain affiliated or related issuers subject to certain exceptions, including
acquisition opportunities made available to Malone solely in his capacity as an
officer of TCI or another covered issuer; (e) for a tag-along right in favor of
the Magness Group with respect to any sale by the Malone Group of High Vote
Shares, subject to certain exceptions such as transfers to certain related
parties; and (f) for a so-called "drag-along" right in favor of Malone. The
"drag-along" right applies to a sale of all or substantially all of the High
Vote Shares beneficially owned by Malone or of the business or assets of TCI,
and permits Malone to require the Magness Group to consent to that sale and, if
the sale takes the form of a sale of Malone's High Vote Shares, to either
convert their High Vote Shares to the corresponding Low Vote Shares or sell that
group's Series B Stock on the same terms as Malone sells his shares.

          For purposes of the Stockholders' Agreement, a "High Vote Share" is
essentially any share of any class or series of TCI capital stock that entitles
the holder to cast more than one vote per share in elections of TCI directors,
while a "Low Vote Share" entitles the holder to cast not more than one such
vote.  High Vote Shares currently consist of TCI's Series B TCI Group Common
Stock, Series B Liberty Media Group Common Stock and Series B Ventures Group
Common Stock, while Low Vote Shares currently consist of TCI's Series A TCI
Group Common Stock, Series A Liberty Media Group Common Stock and Series A
Ventures Group Common Stock.  In some cases, provisions of the Stockholders
Agreement also may apply to certain equity securities of other issuers 

                                      -4-
<PAGE>
 
with which TCI has a specified relationship, including certain issuers that may
be the result of spin-offs by TCI.

          As required by the Settlement Agreement, TCI and the Malone Group also
have entered into a Call Agreement, dated as of February 9, 1998, pursuant to
which the Malone Group granted to TCI a right to acquire all shares of High Vote
Stock owned by them upon Dr. Malone's death.  If that right is exercised, TCI
may acquire the High Vote Stock at a price equal to the market price of the
corresponding Low Vote Stock, plus a 10% premium.  TCI also has a right of first
refusal to purchase High Vote Stock that a member of the Malone Group may
propose to sell to a third party, at a purchase price equal to the lesser of the
price offered by the third party or 110% of the market price of the same number
of the corresponding Low Vote Stock.  In the Call Agreement, the Malone Group
agreed that if TCI is sold to a third party, then the maximum premium the Malone
Group may receive for their High Vote Stock would be the price paid for the
corresponding Low Vote Stock of TCI by that third party, plus a 10% premium.
The Call Agreement also prohibits any member of the Malone Group from disposing
of High Vote Stock, except for certain exempt transfers (such as transfers to
specified related parties or the Magness Group or sales of up to an aggregate of
5% of that member's High Vote Stock after conversion to the corresponding Low
Vote Stock).

     As required by the Settlement Agreement, TCI entered into a similar Call
Agreement with the Magness Group, also dated as of February 9, 1998 (the
"Magness Call Agreement").  Under the Magness Call Agreement, TCI has rights to
acquire all shares of High Vote Stock owned by the Magness Group upon Dr.
Malone's death or in the event of a contemplated sale of shares of such High
Vote Stock to third parties, in each case at a price determined in the manner
and on other terms comparable to TCI's corresponding rights under the Malone
Call Agreement.  If TCI is sold to a third party, then the maximum premium the
Magness Group may receive for their High Vote Stock would be 10%.  The Call
Agreement also prohibits any member of the Magness Group from disposing of High
Vote Stock, except for certain exempt transfers (such as transfers to specified
related parties or the Malone Group, pledges that meet certain requirements and
public sales of up 

                                      -5-
<PAGE>
 
to an aggregate of 5% of that member's High Vote Stock after conversion to the
relevant Low Vote Stock).

     For purposes of each Call Agreement, "High Vote Stock" is TCI Common Stock
of any series that has voting rights greater than one vote per share, while "Low
Vote Stock" is TCI Common Stock of any series that has not more than one vote
per share.  The High Vote Stock is currently comprised of the Series B TCI Group
Common Stock, Series B Liberty Media Group Common Stock and Series B Ventures
Group Common Stock, while the Low Vote Stock is currently comprised of Series A
TCI Group Common Stock, Series A Liberty Media Group Common Stock and Series A
Ventures Group Common Stock.

     As previously announced, in June 1997, TCI granted Malone the right (the
"June Option") to acquire from time to time until June 30, 1999 up to 30,545,864
shares of the Series B TCI Group Stock acquired by TCI from the Estate, in
exchange for either, or any combination of, shares of Series A TCI Group Stock
owned by Malone (exchanged on a one for one basis), or cash in an amount equal
to the average closing sale price of the Series B TCI Group Stock for the five
trading days preceding the acquisition.  In connection with the Settlement
Agreement, the number of shares of the Series B TCI Group Stock subject to that
right was reduced from 30,545,864 to 14,511,570 shares.  Pursuant to the terms
of the Stockholders' Agreement, the Magness Group has the right to participate
in the reduced June Option on a proportionate basis with respect to 12,406,238
shares of the 14,511,570 shares subject to the June Option.

     The foregoing description of the Settlement Agreement, the Malone Call
Agreement, the Magness Call Agreement and the June Option are qualified in their
entirety by reference to the texts of those agreements, copies of which are
filed or incorporated by reference as Exhibits to this Form 8-K.

Magness Estate Shareholders Litigation
- --------------------------------------

     Between January 8 and January 16, 1998, seven putative derivative actions
on behalf of and for the benefit of TCI were filed in the Court of Chancery of
the State of Delaware (the "Delaware Chancery Court") by purported stockholders
of TCI.  These actions are styled as Morgan v. Malone, C.A. No. 16128; Steiner
                                     ----------------                  -------

Partners v. Fisher, C.A. No. 16136; and Deutsch v. Malone, C.A. No. 16148.  The 
- ------------------                      -----------------        
complaints were filed following the announcement of a settlement in the action
styled as In the Matter of the Estate of Bob Magness, Case No. 96 PR 944, in the
          ------------------------------------------      
District Court for the County of Arapahoe in the State of Colorado, in which the
Company and the heirs of TCI founder Bob Magness were litigants. The defendants
named in all seven complaints are nominal defendant TCI and the following TCI
directors: John C. Malone, John W. Gallivan, Donne F. Fisher, Leo J. Hindery,
Jr., J.C. Sparkman, Paul A. Gould, Jerome H. Kern, Kim Magness and Robert A.
Naify. The gravamen of the complaints is that the TCI directors breached their
fiduciary duties by approving the settlement with the Magness Estate, under
whose relevant terms (i) the 1997 sale of the Returned Shares to affiliates of
Merrill Lynch & Co. and Lehman Brothers would be voided; (ii) the Magness Estate
and TCI Chairman and Chief Executive Officer John C. Malone agreed to vote their
stock as a single group; and (iii) TCI acquired the rights to purchase
separately the shares of High Vote Stock held by Malone and the Magness Estate
in exchange for the respective payment by TCI to Malone and the Magness Estate
of $150 million and approximately $124 million. Specifically, the complaints
allege that the TCI Directors impermissibly sought to entrench themselves and
that their approval of the settlement constituted a waste of corporate assets.
The various complaints seek a declaratory judgment that the defendants breached
their fiduciary duties to the Company, an accounting by defendants to TCI for
the damages allegedly sustained by the Company, an accounting by defendant
Malone of his profits from the settlement, the rescission of the settlement, the
repayment by defendant Malone of any payments he has received under the terms of
the settlement, and an award of unspecified compensatory damages.

          AGREEMENT, dated as of February 9, 1998, between Tele-Communications,
Inc., a Delaware corporation ("TCI"), John C. Malone ("Malone") and Leslie
Malone ("Leslie").

          WHEREAS, TCI desires  to have the right to acquire all of the shares
of its Common Stock, $1.00 par value per share, of any series that has voting
rights greater than one vote per share, that are beneficially owned by the other
parties to this Agreement; and

          WHEREAS, each such other party, for himself and his successors

          NOW, THEREFORE, in consideration of the premises and for other good

     surviving entity outstanding immediately after such merger or consolidation
     (or if the Company or the surviving entity after giving effect to such
     transaction is a subsidiary of the issuer of securities in such
     transaction, then the voting power of all voting securities of the Company
     outstanding immediately prior to such transaction represent (by being

     voting power of the issuer outstanding immediately after such merger or

action of the Independent Committee, to purchase all but not less than all of
the shares of High Vote Stock beneficially owned by each Member at the time of

Permitted Transferee of Member Shares in any Exempt Transfer or other
transaction except a sale to a prospective Purchaser in accordance with Section
2.3(b) hereof (collectively for all Members and Permitted Transferees, the
"Subject Shares").  The Company may not exercise its Call Right under this
Section 2.2 unless it concurrently exercises its corresponding call right under

           (b) The Company may exercise the Call Right, by giving written notice
of such exercise (the "Company Notice") to each Member and each such Permitted
Transferee, if any (collectively, the "Holder"), at any time during the period
commencing on and including the date of Malone's death and ending at the Close

any legal action that may be required to confirm the appointment of the personal
representative(s) for the Estate or for the Estate to act through its personal
representative(s) has been completed (such period, the "Call Period").  The date
the Company Notice is given to the Holder is referred to as the "Exercise Date."

           (c) The total consideration payable to the members of the Malone
Group collectively for all of the Subject Shares (the "Gross Purchase Price")
will be an amount equal to the sum of the amounts determined in accordance with
the following formula for each series of High Vote Stock included in the Subject
Shares: 110% of the product of the Per Share Value for such series as of the
date of Malone's death, multiplied by the number of shares of such series
included in the Subject Shares (such amount, as to each series, the "Series
Purchase Price"). In calculating any Series Purchase Price or the Gross Purchase
Price, the number of Subject Shares and the number of shares of any series
included in the Subject Shares shall be calculated without duplication for any
shares that may, by virtue of the definition of "beneficially owned," be deemed
to be beneficially owned by more than one Member.

           (d) The Gross Purchase Price will be payable in cash or, as to any
series of High Vote Stock included in the Subject Shares, in fully paid and
nonassessable shares of Low Vote Stock of the corresponding series, or any
combination of the foregoing, as the Holder may elect, subject to the rights of
the Company pursuant to Section 3.1, by written notice given to the Company at
least 60 days prior to the Closing Date (the "Holder Election Notice").  The
Holder Election Notice shall specify as to each series of High Vote Stock
included in the Subject Shares, the portion of the Series Purchase Price to be
paid in Low Vote Stock of the corresponding series (such portion, as to each
series of High Vote Stock, being the "Series Stock Value" and as to all series
for which payment in 

                                       11
<PAGE>
 
Low Vote Stock has been elected being, in the aggregate, the "Gross Stock
Value"). The Gross Purchase Price less the Gross Stock Value is herein referred
to as the "Closing Date Amount". Subject to the Company's right to elect to
require a public sale in accordance with Section 3, the Closing Date Amount
shall be delivered to the Estate, on behalf of all Members and Permitted
Transferees who held any of the Subject Shares purchased in cash on the Closing
Date.

           (e) If the Holder has timely elected in accordance with Section
2.2(d) to receive any portion of the Gross Purchase Price in shares of Low Vote
Stock, the number of shares of any series of Low Vote Stock to be delivered to
the Holder on the Closing Date shall be equal to the quotient obtained by
dividing (i) the Series Stock Value for the corresponding series of High Vote
Stock by (ii) the Per Share Value of such corresponding series of High Vote
Stock. The shares to be so delivered on the Closing Date will not have been
registered for sale under the Securities Act and may not be sold except pursuant
to an effective registration statement or an exemption from the registration
requirements of the Securities Act. The Company will be under no obligation to
register such shares for resale except as otherwise provided in a Registration
Rights Agreement to be entered into by the Company and the Holder on or prior to
the Closing Date pursuant to which the Company shall grant to the Holder
registration rights with respect to such Shares not less favorable to the Holder
than any registration rights heretofore or hereafter granted by the Company to
any Person and otherwise on terms customary for similar agreements (the
"Registration Rights Agreement"). The certificates for the shares of Low Vote
Stock to be delivered to the Holder on the Closing Date shall bear a customary
legend to the foregoing effect, but shall be free of any rights of the Company
hereunder.

           (f) Amounts payable pursuant to this Agreement in cash shall, unless
otherwise agreed by the Company and the Holder, be paid by wire transfer of next
day funds on or prior to the Closing Date to an account designated in writing by
the Holder at least two (2) Business Days before the Closing Date.

           (g) In the event that there are multiple Holders at the commencement
of the Call Period, then the provisions of this Section 2.2 and of Section 3
shall be applied to each Holder separately, with the applicable shares of High
Vote Stock beneficially owned by a Holder being the Subject Shares with respect
to such Holder and each Holder being entitled to make an election pursuant to
Section 2.2(d), and to have an election made by the Company with respect to it
pursuant to Section 3.1, without regard to the elections made pursuant to said
Sections by or with respect to the other Holders.

     2.3   Acceleration of Call Right.  (a)  During the term of this Agreement,
neither any Member nor any Permitted Transferee shall dispose of any Member
Shares, except in an Exempt Transfer.  If any Related Party of any Member to
whom such Member transfers any Member Shares in an Exempt Transfer ceases to be
a Related Party of its transferor and is not then a Related Party of any other
Permitted Transferee, then unless such Person shall either transfer the Member
Shares held by it to a Member, a Permitted Transferee or a Related Party of
either or otherwise agrees to be bound by this Agreement with respect to such
Member Shares such occurrence shall be deemed 

                                       12
<PAGE>
 
to be a Disposition of the Member Shares then held by such Person giving rise to
the Company's purchase right unless the requirements of the proviso in the
definition of "Related Party" in Section 1.1 hereof are satisfied.

          (b)   (i)   If any Member or any Permitted Transferee (as applicable,
     the "Transferor") receives a bona fide written offer (a "Bona Fide Offer")
     from a Person who is not an Affiliate of any Member or any Permitted
     Transferor (a "Prospective Purchaser") to purchase all or any of the Member
     Shares beneficially owned by the Transferor and the Transferor desires to
     accept the Bona Fide Offer, then prior to the acceptance of the Bona Fide
     Offer by the Transferor, the Call Right shall accelerate as to the Member
     Shares that are the subject of the Bona Fide Offer (the "Offered Shares")
     and the Company may exercise the Call Right in the manner and to the extent
     set forth in this Section 2.3(b).

                (ii)  The Transferor shall give written notice (the "Offer
     Notice") to the Company of its receipt of the Bona Fide Offer and desire to
     accept the same, which notice shall (A) state the identity of the
     Prospective Purchaser and, if the Prospective Purchaser is not its own
     ultimate parent within the meaning of the Hart-Scott-Rodino Antitrust
     Improvements Act of 1976, as amended, the identity of its ultimate
     parent(s) and (B) set forth all material terms of the Bona Fide Offer
     (including the purchase price and the method of payment thereof).  If one
     or more members of the Magness Group exercise their right pursuant to the
     Stockholders Agreement to tag-along on the Bona Fide Offer, the Transferor
     shall set forth in the Offer Notice or in a separate written notice given
     at any time prior to the Closing Date the names of such exercising
     member(s) and the number of shares of High Vote Stock beneficially owned by
     each such member that such member has elected to include in the sale to the
     Prospective Purchaser pursuant to the Stockholders Agreement (such member's
     "Tag-Along Shares").  The Company shall then have the option to exercise
     the Call Right as to all but not less than all of the Offered Shares and
     the Tag-Along Shares (collectively, the "Combined Offered Shares") at the
     applicable price determined in accordance with the following sentence and,
     subject to the remaining provisions of this Section 2.3, on the terms of
     the Bona Fide Offer (as disclosed in the Offer Notice).  The price at which
     the Combined Offered Shares may be purchased by the Company shall be the
     lesser of (x) the price offered in the Bona Fide Offer and (y) an amount
     equal to the Gross Purchase Price, as determined in accordance with Section
     2.2, that would be payable if the Combined Offered Shares were the Subject
     Shares (such lesser amount being, the "Company Price"). The Transferor
     shall enclose with the Offer Notice a true and complete copy of the Bona
     Fide Offer and all documents related thereto.  In determining the Company
     Price, (i) if any portion of the price offered in the Bona Fide Offer
     consisted of consideration other than cash, the fair market value of such
     non-cash consideration shall be deemed to be equal to the amount determined
     by agreement of the Transferor and the Company or, failing such agreement,
     as determined in accordance with the procedures as set forth in Section
     2.3(c); and the number of Subject Shares and the number of shares of any
     series included in the Subject Shares shall be calculated without
     duplication for any shares that may, by virtue of 

                                       13
<PAGE>
 
     the definition of "beneficially owned," be deemed to be beneficially owned
     by more than one Member.

                (iii) The Company shall have the right, exercisable (if so
     determined by the Independent Committee) by the written notice (an
     "Election Notice") given to the Transferor on or before the Close of
     Business on the tenth (10th) Business Day after receipt of the Offer
     Notice, to exercise the Call Right as to the Combined Offered Shares and to
     purchase all but not less than all of the Combined Offered Shares.  If the
     Company duly delivers an Election Notice for the Combined Offered Shares in
     accordance with the foregoing procedure, it shall (subject to the Company's
     right to elect to pay a portion of the Company Price in debt securities in
     accordance with Section 2.3(b)(iv) and subject to the Company's right to
     elect to require a public sale in accordance with Section 3.1), purchase
     the Combined Offered Shares for cash, paid by wire transfer of next day
     funds on or prior to the Closing Date to an account designated by the
     Transferor in writing at least two (2) Business Days before such date.
     Notwithstanding the date fixed as the Closing Date in Section 4.1, the
     Closing Date for the purchase and sale of the Combined Offered Shares
     pursuant to this Section 2.3 shall be subject to extension in accordance
     with Section 2.3(c).

                (iv)  In the event that the Company Price is the price offered
     in the Bona Fide Offer and any part of the price specified in the Bona Fide
     Offer is proposed to be paid in debt securities, the Company may, in its
     discretion, elect to pay the equivalent portion of the Company Price
     through the issuance of debt securities with substantially similar terms in
     an amount the fair market value of which is equal to the fair market value
     of the equivalent portion of the debt securities specified in the Offer
     Notice, in each case as agreed by the Company and the Transferor or,
     failing such agreement, as determined in accordance with the procedures
     specified in Section 2.3(c), taking into consideration relevant credit
     factors relating to the Prospective Purchaser and the Company and the
     marketability and liquidity of such debt securities.

                (v)   In the event that (A) no Election Notice has been given by
     the tenth (10th) Business Day after receipt of the Offer Notice, or (B) if
     an Election Notice is given, the Closing has not occurred by the 61st day
     after the Election Notice is given (or such later date as the parties may
     have scheduled for the Closing or to which the Closing may have been
     extended pursuant to Section 2.3(c), for any reason other than a breach by
     the Transferor or another Member or Permitted Transferee of its obligations
     hereunder (the first to occur of such events being the "Free to Sell
     Date"), then each Person included within the Transferor shall have the
     right to sell all but not less than all of the Combined Offered Shares of
     such Person to the Prospective Purchaser at the price (or a greater price)
     and upon the terms (or terms no more favorable to the Prospective
     Purchaser) specified in the Offer Notice and, in connection with any such
     sale such Person shall not be required to convert any of such Offered
     Shares into shares of Low Vote Stock prior to the sale to such Prospective
     Purchaser.  The right to sell Combined Offered Shares to the Prospective
     Purchaser pursuant to this Section 2.3(b)(v) shall expire and the
     provisions of this Section 2.3(b) shall be 

                                       14
<PAGE>
 
     reinstated in the event that the Prospective Purchaser has not purchased
     such Combined Offered Shares within ten (10) Business Days after the Free
     to Sell Date.

          (c)   (i)   If a Bona Fide Offer proposes to pay a portion of the
     price for the Offered Shares in consideration other than cash and the
     Company and the Transferor have not agreed upon the value thereof (or, in
     the case of debt securities, if the Company has elected to pay a portion of
     the Company Price in equivalent securities and the Company and the
     Transferor have not agreed upon the value of the debt securities the
     Company proposes to issue) by the Close of Business on the fifth (5th)
     Business Day prior to the date otherwise fixed for the Closing (the
     "Commencement Date") then the procedures set forth in this Section 2.3(c)
     shall be commenced and the Closing Date shall be extended to the fifth
     (5th) Business Day following the date on which the fair market value of the
     noncash consideration (or Company issued debt securities) has been finally
     determined pursuant to this Section 2.3(c).

                (ii)  The Company and the Transferor shall each retain a
     Qualified Appraiser and notify the other party of its selection within five
     (5) Business Days of the Commencement Date to render the determination
     required by this Section 2.3(c). If either party fails to timely select its
     Qualified Appraiser then the Qualified Appraiser selected by the other
     party shall render such determination. The Company and the Transferor shall
     each be responsible for the fees and expenses of the Qualified Appraiser
     selected by it, unless only one Qualified Appraiser is selected in which
     case the Company and the Transferor shall each bear 50% of such fees and
     expenses. If a Third Appraiser is selected pursuant to this Section 2.3(c)
     the fees and expenses of the Third Appraiser will be shared equally by the
     Company and the Transferor.

                (iii) The Qualified Appraisers selected by the parties shall
     submit their respective independent determinations of the fair market value
     of the noncash consideration (and, if applicable, Company issued debt
     securities), within 15 Business Days after the Commencement Date.  If the
     respective determinations of such Qualified Appraisers vary by less than
     ten percent (10%), the fair market value of the noncash consideration (and,
     if applicable, Company issued debt securities) shall be the average of the
     two determinations.

                (iv)  If such respective determinations vary by ten percent
     (10%) or more, the two Appraisers shall promptly designate a third
     Qualified Appraiser (the "Third Appraiser"). No party to this Agreement or
     any Affiliate of any party to this Agreement or Qualified Appraiser shall,
     provide any information to the Third Appraiser as to the determinations of
     the initial Qualified Appraisers or otherwise influence the Third
     Appraiser's determination in any way. The Third Appraiser shall submit its
     determination of the fair market value of the noncash consideration (and,
     if applicable, Company issued debt securities), within ten (10) Business
     Days after the date on which the Third Appraiser is retained. If a Third
     Appraiser is retained, the fair market value of the noncash

                                       15
<PAGE>
 
     consideration (and, if applicable, Company issued debt securities) shall
     equal the average of the two closest of the three determinations, except
     that, if the difference between the highest and middle determinations is no
     more than 105% and no less than 95% of the difference between the middle
     and lowest determinations, then the fair market value shall equal the
     middle determination.

              (v)  In determining the fair market value of the noncash
     consideration (and, if applicable, the Company issued debt securities),
     each Qualified Appraiser retained pursuant to this Section 2.3(c) shall:
     (i) assume that the fair market value of the applicable asset is the price
     at which the asset would change hands between a willing buyer and a willing
     seller, neither being under any compulsion to buy or sell and each having
     reasonable knowledge of all relevant facts; (ii) assume that the applicable
     asset would be sold for cash; and (iii) use valuation techniques then
     prevailing in the relevant industry.

          (d) No voluntary transfers of Member Shares may be made by any Holder
during the Call Period and if the Call Right is exercised, thereafter, except to
the Company pursuant to the Call Right.  Accordingly, without limiting the
generality of the foregoing, no voluntary transfer may be made during such
period pursuant to a Bona Fide Offer, notwithstanding the Transferor's
compliance with this Section 2.3 prior to Malone's death.

          (e) If there shall be more than one Transferor in any transaction or
series of related transactions covered by an Offer Notice, and if, to the extent
permitted by this Agreement, the Company pays the Company Price with more than
one form of consideration, then unless otherwise agreed in writing by the
Transferors, each Transferor shall receive on a per share basis substantially
the same combination of consideration.

          (f) Notwithstanding anything in this Agreement to the contrary, one
or more Members may, at any time and from time to time, sell a number of Member
Shares that in the aggregate for all transfers made pursuant to this subsection
by any or all of the Members is equal to or less than the number of Excepted
Shares.  Prior to the consummation of a disposition of any Member Shares in
accordance with this Section 2.3(f), such Member Shares must be converted into
shares of Low Vote Stock of the corresponding series.  The number of any Member
Shares disposed of pursuant to this Section 2.3(f) shall be subtracted from the
number of Excepted Shares.  Upon the consummation of a disposition of Member
Shares pursuant to this Section 2.3(f), the Member disposing of such Member
Shares shall deliver to the Company a written notice stating the number of
Member Shares so disposed of by such Member and the aggregate number of Excepted
Shares which such Member continues to beneficially own.

 3.  Public Sale Election.

     3.1  Company Election.  (a) Notwithstanding anything in Section 2.2(d) or
Section 2.3(b)(iii) to the contrary, but subject to Section 2.3(e), the Company
shall have the right to pay all or any portion of the Closing Date Amount or
Company Price, as applicable, in shares of Low Vote 

                                       16
<PAGE>
 
Stock in accordance with the following procedures. At least five (5) Business
Days prior to the Closing Date, the Company shall notify (the "Public Sale
Notice") the Holder or each Transferor, as the case may be, as to the portion of
the Closing Date Amount or Company Price, as applicable, to be paid in shares of
Low Vote Stock (the "Public Sale Dollar Amount"). The number of shares of Low
Vote Stock (the "Resale Stock") deliverable to the Underwriters pursuant to
Section 3.2 shall be that number of shares which when sold in accordance with
Section 3.2 will reasonably be expected to yield aggregate net proceeds
collectively to all the Member(s), Permitted Transferee(s), Members of the
Magness Group and other Persons, if any, participating in the sale
(collectively, the "Seller") (after deduction of underwriting discounts and
commissions and assuming the payment by the Company of all other expenses of
registration and sale of the Resale Stock) of an aggregate amount equal to the
Stock Proceeds Amount.

          (b) The term "Stock Proceeds Amount" shall mean the sum of  (i) Public
Sale Dollar Amount, plus (ii) interest on the Public Sale Dollar Amount,
accruing from and including the Closing Date to the date of payment pursuant to
Section 3.2, at a rate equal to the weighted average interest rate applicable as
of the Closing Date to that portion of the consolidated indebtedness of the
Company that bears interest at a floating interest rate.

          (c) Subject to the foregoing, the decision as to which series of Low
Vote Stock and the number of shares of each such series that will comprise the
Resale Stock shall be made by the Company at its discretion.  Such shares shall
be held by the Company on behalf of the Seller pending the Sales, and the
Company shall be authorized to deliver such shares to the Underwriters on such
Seller's behalf prior to the closing of the Sales.

      3.2 Public Sale.   (a) On the Closing Date, the Company shall provide an
effective registration statement (the "Registration Statement") registering
under the Securities Act resales of the Resale Stock deliverable pursuant to
Section 3.1 having a maximum aggregate offering price (net of underwriting fee
and commissions) equal to the Stock Proceeds Amount.  Such Resale Stock shall be
sold (at the Company's discretion but in the form of one or more secondary
offerings on behalf of each Seller) under the Registration Statement during the
period of not more than 45 days following the Closing Date as specified by the
Company (the "Offering Period").  The Company may by notice to each Seller at
any time shorten the Offering Period, and in such event, the Offering Period as
referred to herein shall mean such shorter period.  All sales (the "Sales") of
the Resale Stock shall be made on behalf of each Seller by underwriters selected
by the Company (the "Underwriters") pursuant to one or more block trades,
underwritten offerings or otherwise, in each case as determined by the Company.
The actual net proceeds from the Sales (after deduction of underwriting
discounts and commissions) are referred to as the "Net Proceeds".  The Company
shall pay all expenses of registration and sale of the Resale Stock.

          (b) On the fifth Business Day following the termination of the
Offering Period, the Company shall deliver to each Seller such Seller's pro rata
portion of the Net Proceeds and if the Net Proceeds are less than the Stock
Proceeds Amount, the difference (the "Difference") shall be paid by the Company
in cash on such date to Sellers on a pro rata basis.  The Company may elect 

                                       17
<PAGE>
 
to pay some or all of the Difference prior to such date and in such event the
interest component of the portion of the Difference so paid early shall be
calculated with respect to such earlier payment date. If the Net Proceeds exceed
the Stock Proceeds Amount, the Company may retain the excess.

          (c) The Company shall indemnify each Seller and the Underwriters in
respect of the Sales to the same extent as the Company would indemnify the
Holder and the Underwriters as provided in the Registration Rights Agreement,
but the Sales shall not be deemed to have been made pursuant to the Registration
Rights Agreement.

          (d) Each Seller shall be required to cooperate with the Company in
connection with the Registration Statement and the Sales (including, without
limitation, by executing and delivering underwriting and other documents and
instruments, taking actions and providing information) as shall be reasonably
requested by the Company in connection therewith.

 4.  Closing Matters.

      4.1 Closing Date.  The consummation of the purchase and sale of (i) the
Subject Shares following the exercise of the Call Right pursuant to Section 2.2
or (ii) the Combined Offered Shares following the exercise of the Call Right
pursuant to Section 2.3 (in each case, a "Closing") shall be held at 10:00 a.m.
local time on, respectively, (x) the 155th day following the Exercise Date, or
(y) the 60th day following the date the Election Notice is given or (z) such

offices of the Company or at such other place as the Malone or the Estate (as
the case may be) and the Company may agree.

      4.2 Closing Deliveries.    At the Closing, the Company shall pay to the
Member(s) and Permitted Transferee(s), if any, comprising the Seller (i) any

required to be paid in cash in the manner provided in Section 2.2(f) or Section
2.3(b)(iii), as and if applicable, (ii) deliver certificate(s) registered in the
name of each Seller for the number of shares of Low Vote Stock required to be
delivered in payment of the Gross Stock Value portion of the Gross Purchase
Price, and (iii) if the Company has elected to pay any or all of the Closing
Date Amount or Company Price, as applicable, in shares of Low Vote Stock
pursuant to Section 3.1, deliver the Registration Statement conforming to the
requirements of Section 3.2.  At the Closing, each of the Member(s) and
Permitted Transferee(s), if any, participating in the sale shall be required, as
a condition to receiving payment, to deliver to the Company (i) a stock
certificate or certificates, duly endorsed for transfer or in blank,
representing such Person's Subject Shares or Combined Offered Shares, as
applicable, (ii) if applicable, copies of Letters Testamentary or other
documentation evidencing the authority of such Person to transfer any of the
Subject Shares that are evidenced by certificates registered in the name of a
Person other than such Seller, (iii) a certificate, executed by or on behalf of

charges or encumbrances and has the legal authority to consummate such sale and
(iv) such other certificates and documents as the Company may reasonably
request.

     is the Company, the execution, delivery and performance of this Agreement
     by the Company has been duly authorized by all necessary action on its
     part.  This Agreement has been duly executed and delivered by such party
     and constitutes the valid and binding obligation of such party enforceable

          (b) The execution, delivery and performance of this Agreement by such
     party, and the compliance by such party with the provisions hereof, do not
     and will not (with or without notice or lapse of time, or both) conflict
     with, or result in any violation of, or default under, or give rise to any
     right of termination, cancellation or acceleration of any obligation or to
     loss of a material benefit under, any loan or credit agreement, note, bond,
     mortgage, indenture, lease or other agreement, instrument, permit,

     ordinance, rule or regulation applicable to such party or any of his or its
     properties or assets, other than any such conflicts, violations, defaults,
     or other effects which individually or in the aggregate do not and will not
     prevent, restrict or impede such party's performance of his or its

     respect to the exercise of certain rights granted hereunder, in connection
     with Federal and state securities laws.

          5.2  General Covenants.   (a)  In the event that any sale of shares
pursuant to this Agreement would violate any rules or regulations of any
governmental or regulatory agency having jurisdiction or any other material law,
rule, regulation, order, judgment or decree applicable to the 

                                       19
<PAGE>
 
parties hereto (including, with respect to the Company, its subsidiaries or any
of the Company's or such subsidiary's respective properties and assets), then
each party hereto hereby agrees (i) to cooperate with and assist the other in
filing such applications and giving such notices, (ii) to use reasonable efforts
to obtain, and to assist the other in obtaining, such consents, approvals and
waivers, and (iii) to take such other actions, including supplying all
information necessary for any filing, as any affected party may reasonably
request, all as and to the extent necessary or advisable so that the
consummation of such sale will not constitute or result in such a violation.

          (b) Each party hereto hereby further agrees that he or it shall not
take any action or enter into any agreement or arrangement restricting or
limiting his or its ability timely and fully to perform all his or its
obligations under this Agreement.

6.  Stockholder's Covenant Relating to a Sale of Company.

      6.1 Limitation on Size of Premium.  (a) In connection with any proposed
Sale of the Company, each Member agrees not to negotiate for or require as a
term of such transaction or as a condition to his agreement to vote therefor
that either (i) the holders of High Vote Stock receive for such High Vote Stock
or (ii) any Member or any Related Party or Affiliate of any Member receives for
the shares of High Vote Stock or Common Stock beneficially owned by any of them,
consideration the value of which on a per share basis exceeds the value per
share payable to (x) holders of shares of Low Vote Stock into which such High
Vote Stock is convertible or (y) holders of Common Stock other than any Member
or any Related Party or Affiliate of any Member, in either case by more than ten
percent (10%) (a "Prohibited Premium").  For the purposes of computing the
existence of a Prohibited Premium, if any noncash consideration to be received
by any holders of Common Stock in any proposed Sale of the Company is the same
for both (A) (i) the holders of High Vote Stock or (ii) any Member or any
Related Party or Affiliate of any Member, as applicable, and (B) (x) holders of
shares of Low Vote Stock into which such High Vote Stock is convertible or (y)
holders of Common Stock other than any Member or any Related Party or Affiliate
of any Member, as applicable, a Prohibited Premium shall be deemed to exist if
the ratio of such noncash consideration given to the Persons listed in (A) above
exceeds the amount of such noncash consideration given to the Persons listed in
(B) above by more than ten percent (10%).  If different forms of noncash
consideration are to be given to the Persons listed in (A) above than to the
Persons listed in (B) above, and there is any disagreement between the
Independent Committee and any such Person as to the value of any such
consideration for the purposes of determining if there is a Prohibited Premium,
then the noncash consideration shall be valued by using the appraisal procedures
set forth in Section 2.3(c).

          (b) If a proposed Sale of the Company containing a Prohibited Premium
is submitted to the stockholders of the Company for a vote, each Member agrees
that he will vote all of his Member Shares, and any other shares of voting stock
entitled to vote on such proposal beneficially owned by him, against such
proposal.

7.  Miscellaneous.
 
     7.1  Term.  This Agreement shall continue in full force and effect until
the first to occur of the following: (i) all of the Member Shares have been
purchased by the Company, (ii) all of the Member Shares have been sold to one or
more Prospective Purchasers in compliance with Section 2.3(b) and (ii) the Call
Right under Section 2.2 has expired unexercised.

than those as to which it has been held invalid or unenforceable, shall remain
in full force and effect and shall in no way be affected, impaired or
invalidated thereby, provided, that if any provision hereof or the application
thereof shall be so held to be invalid, void or unenforceable by a court of
competent jurisdiction, then such court may substitute therefor a suitable and
equitable provision in order to carry out, so far as may be valid and
enforceable, the intent and purpose of the invalid, void or unenforceable
provision and, if such court shall fail or decline to do so, the parties shall
negotiate in good faith in an effort to agree upon such a suitable and equitable
provision.

legal process in any other manner permitted by law or affect the right of any
party to bring any action or proceeding against any other party or its property

estate, heirs, administrators, executors, other legal representatives,
successors and assigns, hereby grants to the Company the call right, as provided
in Section 2.2 and Section 2.3 of this Agreement, and makes the covenants for

right and the making of such covenants, on or prior to February 9, 1998 (or on
such earlier or later date as the parties to numbered paragraph 4 of the
Settlement Agreement may agree), the Company shall pay the Magness Group,
collectively, the aggregate sum equal to the Grant Consideration Amount.  The
"Grant Consideration Amount" shall be the sum, determined after giving effect to
all transfers of High Vote Stock of any class or series required by the
Settlement Agreement on or before such date, of the respective products obtained
by multiplying the aggregate number of shares of High Vote Stock of each class

the date of payment by the same per share dollar amount, if any, paid by the
Company to the members of the Malone Group for each share of High Vote Stock of
that class or series beneficially owned by them pursuant to Section 2.1 of the

parties estimate that the Grant Consideration Amount will be approximately One
Hundred and Twenty-Four Million Dollars ($124,000,000), but the actual Grant
Consideration Amount will be the amount determined as provided above in this
Section 2.1.  The Grant Consideration Amount shall be 

                                       12
<PAGE>
 
allocated among the grant of the call right hereunder, the grant of the
acceleration feature of such call right contained herein and the making of the
other covenants contained herein in the same proportions (subject to rounding
differences) as the amount of the payment to Malone under Section 2.1 of the
Malone Call Agreement is allocated among the comparable items of the Malone Call
Agreement. Such payment shall be made when due in cash by wire transfer of next
day funds to an account designated by the Magness Group Representative. Such
payment shall be allocated among the Members in any manner in which they agree
among themselves. Without limiting the generality of Section 7.1, the Company
shall be entitled to rely exclusively and conclusively on information provided
by the Magness Group Representative as to any such allocation or other matters
in connection with the exercise of the rights of the Magness Group and each of
its Members under this Agreement and shall not, in any event, have any liability
to any Member as a result of such reliance. The Company shall not be obligated
to make such payment unless or until the actions contemplated by numbered
paragraph 4 of the Settlement Agreement are duly taken on a timely basis or if
this Agreement, the Malone Call Agreement or the Stockholders Agreement is
terminated or subject to termination under Section 6.20(d) or 6.20(e) of the
Stockholders Agreement. Each member of the Magness Group shall provide such
information and otherwise cooperate with the Company in such manner as the
Company shall reasonably request in order to determine and verify the number of
shares of High Vote Stock of each class or series beneficially owned by the
Magness Group on the date of the payment provided for in this Section.

      2.2  Call Right.  (a)     Subject to the last sentence of this subsection
(a), upon Malone's death, the Company shall have the right (the "Call Right"),
exercisable by action of the Independent Committee, to purchase all but not less
than all of the shares of High Vote Stock beneficially owned by each Member at
the time of Malone's death and all but not less than all of the shares of High
Vote Stock that are then beneficially owned by any Permitted Transferee of any
Member and which shares were acquired directly or indirectly from a Member or
another Permitted Transferee of Member Shares in any Exempt Transfer or other
transaction except a sale to a prospective Purchaser in accordance with Section
2.3(b) hereof (collectively for all Members and Permitted Transferees, the
"Subject Shares"). The Company may not exercise its Call Right under this
Section 2.2 unless it concurrently exercises its corresponding call right under
the corresponding provisions of the Malone Call Agreement.

           (b) The Company may exercise the Call Right, by giving written notice
of such exercise (the "Company Notice") to each Member and each such Permitted
Transferee, if any (collectively, the "Holder"), at any time during the period
commencing on and including the date of Malone's death and ending at the Close
of Business on the 50th day after the date, following Malone's death, on which
any legal action that may be required to confirm the appointment of the personal
representative(s) for Malone's estate or for Malone's estate to act through its
personal representative(s) has been completed (such period, the "Call Period").
The date the Company Notice is given to the Holder is referred to as the
"Exercise Date."

           (c) The total consideration payable to the members of the Magness
Group collectively for all of the Subject Shares (the "Gross Purchase Price")
will be an amount equal to the 

                                       13
<PAGE>
 
sum of the amounts determined in accordance with the following formula for each
series of High Vote Stock included in the Subject Shares: 110% of the product of
the Per Share Value for such series as of the date of Malone's death, multiplied
by the number of shares of such series included in the Subject Shares (such
amount, as to each series, the "Series Purchase Price"). In calculating any
Series Purchase Price or the Gross Purchase Price, the number of Subject Shares
and the number of shares of any series included in the Subject Shares shall be
calculated without duplication for any shares that may, by virtue of the
definition of "beneficially owned," be deemed to be beneficially owned by more
than one Member.

          (d) The Gross Purchase Price will be payable in cash or, as to any
series of High Vote Stock included in the Subject Shares, in fully paid and
nonassessable shares of Low Vote Stock of the corresponding series, or any
combination of the foregoing, as the Magness Group Representative, on behalf of
the Holder, may elect, subject to the rights of the Company pursuant to Section
3.1, by written notice given to the Company at least 60 days prior to the
Closing Date (the "Holder Election Notice").  The Holder Election Notice shall
specify as to each series of High Vote Stock included in the Subject Shares, the
portion of the Series Purchase Price to be paid in Low Vote Stock of the
corresponding series (such portion, as to each series of High Vote Stock, being
the "Series Stock Value" and as to all series for which payment in Low Vote
Stock has been elected being, in the aggregate, the "Gross Stock Value").  The
Gross Purchase Price less the Gross Stock Value is herein referred to as the
"Closing Date Amount".  Subject to the Company's right to elect to require a
public sale in accordance with Section 3, the Closing Date Amount shall be
delivered to the Magness Group Representative, on behalf of all Members and
Permitted Transferees who held any of the Subject Shares purchased in cash on
the Closing Date.

          (e) If the Holder has timely elected in accordance with Section 2.2(d)
to receive any portion of the Gross Purchase Price in shares of Low Vote Stock,
the number of shares of any series of Low Vote Stock to be delivered to the
Holder on the Closing Date shall be equal to the quotient obtained by dividing
(i) the Series Stock Value for the corresponding series of High Vote Stock by
(ii) the Per Share Value of such corresponding series of High Vote Stock.  The
shares to be so delivered on the Closing Date will not have been registered for
sale under the Securities Act and may not be sold except pursuant to an
effective registration statement or an exemption from the registration
requirements of the Securities Act.  The Company will be under no obligation to
register such shares for resale except as otherwise provided in a Registration
Rights Agreement to be entered into by the Company and the Holder on or prior to
the Closing Date pursuant to which the Company shall grant to the Holder
registration rights with respect to such Shares not less favorable to the Holder
than any registration rights granted by the Company to Malone pursuant to the
Malone Call Agreement (the "Registration Rights Agreement").  The certificates
for the shares of Low Vote Stock to be delivered to the Holder on the Closing
Date shall bear a customary legend to the foregoing effect but shall be free of
any rights of the Company hereunder.

          (f) Amounts payable pursuant to this Agreement in cash shall, unless
otherwise agreed by the Company and the Magness Group Representative, be paid by
wire transfer of next day 

                                       14
<PAGE>
 
funds on or prior to the Closing Date to an account designated in writing by the
Magness Group Representative at least two (2) Business Days before the Closing
Date.

     2.3  Acceleration of Call Right.  (a)  During the term of this Agreement,
neither any Member nor any Permitted Transferee shall dispose of any Member
Shares, except in an Exempt Transfer.  If any Related Party of any Member to
whom such Member transfers any Member Shares in an Exempt Transfer ceases to be
a Related Party of its transferor and is not then a Related Party of any other
Member or Permitted Transferee, then such occurrence shall be deemed to be a
Disposition of the Member Shares then held by such Person giving rise to the
Company's purchase right unless the requirements of the proviso in the
definition of "Related Party" in Section 1.1 hereof are satisfied.

          (b)   (i)  If any Member or any Permitted Transferee (as applicable,
     the "Transferor") receives a bona fide written offer (a "Bona Fide Offer")
     from a Person who is not an Affiliate of any Member or any Permitted
     Transferee (a "Prospective Purchaser") to purchase all or any of the Member
     Shares beneficially owned by the Transferor and the Transferor desires to
     accept the Bona Fide Offer, then prior to the acceptance of the Bona Fide
     Offer by the Transferor, the Call Right shall accelerate as to the Member
     Shares that are the subject of the Bona Fide Offer (the "Offered Shares")
     and the Company may exercise the Call Right in the manner and to the extent
     set forth in this Section 2.3(b).

               (ii)  The Transferor shall give written notice (the "Offer
     Notice") to the Company of its receipt of the Bona Fide Offer and desire to
     accept the same, which notice shall (A) state the identity of the
     Prospective Purchaser and, if the Prospective Purchaser is not its own
     ultimate parent within the meaning of the Hart-Scott-Rodino Antitrust
     Improvements Act of 1976, as amended, the identity of its ultimate
     parent(s) and (B) set forth all material terms of the Bona Fide Offer
     (including the purchase price and the method of payment thereof).  The
     Company shall then have the option to exercise the Call Right as to all but
     not less than all of the Offered Shares at the applicable price determined
     in accordance with the following sentence and, subject to the remaining
     provisions of this Section 2.3, on the terms of the Bona Fide Offer (as
     disclosed in the Offer Notice).  The price at which the Offered Shares may
     be purchased by the Company shall be the lesser of (x) the price offered in
     the Bona Fide Offer and (y) an amount equal to the Gross Purchase Price, as
     determined in accordance with Section 2.2, that would be payable if the
     Offered Shares were the Subject Shares (such lesser amount being, the
     "Company Price").  The Transferor shall enclose with the Offer Notice a
     true and complete copy of the Bona Fide Offer and all documents related
     thereto.  In determining the Company Price, (i) if any portion of the price
     offered in the Bona Fide Offer consisted of consideration other than cash,
     the fair market value of such non-cash consideration shall be deemed to be
     equal to the amount determined by agreement of the Transferor and the
     Company or, failing such agreement, as determined in accordance with the
     procedures as set forth in Section 2.3(c); and (ii) the number of Subject
     Shares and the number of shares of any series included in the Subject
     Shares shall 

                                       15
<PAGE>
 
     be calculated without duplication for any shares that may, by virtue of the
     definition of "beneficially owned," be deemed to be beneficially owned by
     more than one Member.

               (iii)  The Company shall have the right, exercisable (if so
     determined by the Independent Committee) by the written notice (an
     "Election Notice") given to the Transferor on or before the Close of
     Business on the tenth (10th) Business Day after receipt of the Offer
     Notice, to exercise the Call Right as to the Offered Shares and to purchase
     all but not less than all of the Offered Shares.  If the Company duly
     delivers an Election Notice for the Offered Shares in accordance with the
     foregoing procedure, it shall (subject to the Company's right to elect to
     pay a portion of the Company Price in debt securities in accordance with
     Section 2.3(b)(iv) and subject to the Company's right to elect to require a
     public sale in accordance with Section 3.1), purchase the Offered Shares
     for cash, paid by wire transfer of next day funds on or prior to the
     Closing Date to an account designated by the Transferor in writing at least
     two (2) Business Days before such date.  Notwithstanding the date fixed as
     the Closing Date in Section 4.1, the Closing Date for the purchase and sale
     of the Offered Shares pursuant to this Section 2.3 shall be subject to
     extension in accordance with Section 2.3(c).

               (iv)  In the event that the Company Price is the price offered in
     the Bona Fide Offer and any part of the price specified in the Bona Fide
     Offer is proposed to be paid in debt securities, the Company may, in its
     discretion, elect to pay the equivalent portion of the Company Price
     through the issuance of debt securities with substantially similar terms in
     an amount the fair market value of which is equal to the fair market value
     of the equivalent portion of the debt securities specified in the Offer
     Notice, in each case as agreed by the Company and the Transferor or,
     failing such agreement, as determined in accordance with the procedures
     specified in Section 2.3(c), taking into consideration relevant credit
     factors relating to the Prospective Purchaser and the Company and the
     marketability and liquidity of such debt securities.

               (v) In the event that (A) no Election Notice has been given by
     the tenth (10th) Business Day after receipt of the Offer Notice, or (B) if
     an Election Notice is given, the Closing has not occurred by the 61st day
     after the Election Notice is given (or such later date as the parties may
     have scheduled for the Closing or to which the Closing may have been
     extended pursuant to Section 2.3(c), for any reason other than a breach by
     the Transferor or another Member or Permitted Transferee of its obligations
     hereunder (the first to occur of such events being the "Free to Sell
     Date"), then the Transferor shall have the right to sell all but not less
     than all of the Offered Shares to the Prospective Purchaser at the price
     (or a greater price) and upon the terms (or terms no more favorable to the
     Prospective Purchaser) specified in the Offer Notice and, in connection
     with any such sale the Transferor shall not be required to convert any of
     the Offered Shares into shares of Low Vote Stock prior to the sale to such
     Prospective Purchaser.  The Transferor's right to sell the Offered Shares
     to the Prospective Purchaser pursuant to this Section 2.3(b)(v) shall
     expire and the provisions of this Section 2.3(b) shall be reinstated in the
     event that the Prospective 

                                       16
<PAGE>
 
     Purchaser has not purchased such Offered Shares within ten (10) Business
     Days after the Free to Sell Date.

          (c)   (i)  If a Bona Fide Offer proposes to pay a portion of the price
     for the Offered Shares in consideration other than cash and the Company and
     the Transferor have not agreed upon the value thereof (or, in the case of
     debt securities, if the Company has elected to pay a portion of the Company
     Price in equivalent securities and the Company and the Transferor have not
     agreed upon the value of the debt securities the Company proposes to issue)
     by the Close of Business on the fifth (5th) Business Day prior to the date
     otherwise fixed for the Closing (the "Commencement Date") then the
     procedures set forth in this Section 2.3(c) shall be commenced and the
     Closing Date shall be extended to the fifth (5th) Business Day following
     the date on which the fair market value of the noncash consideration (or
     Company issued debt securities) has been finally determined pursuant to
     this Section 2.3(c).

               (ii) The Company and the Transferor shall each retain a Qualified
     Appraiser and notify the other party of its selection within five (5)
     Business Days of the Commencement Date to render the determination required
     by this Section 2.3(c).  If either party fails to timely select its
     Qualified Appraiser then the Qualified Appraiser selected by the other
     party shall render such determination.  The Company and the Transferor
     shall each be responsible for the fees and expenses of the Qualified
     Appraiser selected by it, unless only one Qualified Appraiser is selected
     in which case the Company and the Transferor shall each bear 50% of such
     fees and expenses.  If a Third Appraiser is selected pursuant to this
     Section 2.3(c) the fees and expenses of the Third Appraiser will be shared
     equally by the Company and the Transferor.

               (iii)  The Qualified Appraisers selected by the parties shall
     submit their respective independent determinations of the fair market value
     of the noncash consideration (and, if applicable, Company issued debt
     securities), within 15 Business Days after the Commencement Date.  If the
     respective determinations of such Qualified Appraisers vary by less than
     ten percent (10%), the fair market value of the noncash consideration (and,
     if applicable, Company issued debt securities) shall be the average of the
     two determinations.

               (iv)  If such respective determinations vary by ten percent (10%)
     or more, the two Appraisers shall promptly designate a third Qualified
     Appraiser (the "Third Appraiser").  No party to this Agreement or any
     Affiliate of any party to this Agreement or Qualified Appraiser shall,
     provide any information to the Third Appraiser as to the determinations of
     the initial Qualified Appraisers or otherwise influence the Third
     Appraiser's determination in any way.  The Third Appraiser shall submit its
     determination of the fair market value of the noncash consideration (and,
     if applicable, Company issued debt securities), within ten (10) Business
     Days after the date on which the Third Appraiser is retained.  If a Third
     Appraiser is retained, the fair market value of the noncash consideration
     (and, if applicable, Company issued debt securities) shall equal the
     average of 

                                       17
<PAGE>
 
     the two closest of the three determinations, except that, if the difference
     between the highest and middle determinations is no more than 105% and no
     less than 95% of the difference between the middle and lowest
     determinations, then the fair market value shall equal the middle
     determination.

               (v) In determining the fair market value of the noncash
     consideration (and, if applicable, the Company issued debt securities),
     each Qualified Appraiser retained pursuant to this Section 2.3(c) shall:
     (A) assume that the fair market value of the applicable asset is the price
     at which the asset would change hands between a willing buyer and a willing
     seller, neither being under any compulsion to buy or sell and each having
     reasonable knowledge of all relevant facts; (B) assume that the applicable
     asset would be sold for cash; and (C) use valuation techniques then
     prevailing in the relevant industry.

          (d) No voluntary transfers of Member Shares may be made by any Holder
during the Call Period and if the Call Right is exercised, thereafter, except
(i) to the Company pursuant to the Call Right or (ii) in the case of any pre-
existing Permitted Pledge that continues to qualify as a Permitted Pledge, a
transfer of the pledged Member Shares to the pledgee (or its nominee) as a
result of the bona fide exercise by such pledgee of its rights and remedies as
              ---- ----                                                       
contemplated by the definition of "Permitted Pledge" in Section 1.1 hereof, but
not any further transfer by such assignee (it being understood that a conversion
by the pledgee of the pledged Member Shares into shares of Low Vote Stock in the
manner and on the terms set forth in the definition of "Permitted Pledge" in
Section 1.1 hereof shall be permitted).  Accordingly, without limiting the
generality of the foregoing, no voluntary transfer may be made during such
period pursuant to a Bona Fide Offer, notwithstanding the Transferor's
compliance with this Section 2.3 prior to Malone's death.

          (e) If there shall be more than one Transferor in any transaction or
series of related transactions covered by an Offer Notice, and if, to the extent
permitted by this Agreement, the Company pays the Company Price with more than
one form of consideration, then unless otherwise agreed in writing by the
Transferors or by the Magness Group Representative on their behalf, each
Transferor shall receive on a per share basis substantially the same combination
of consideration.

          (f)  Notwithstanding anything in this Agreement to the contrary, one
or more Members may, at any time and from time to time, sell a number of Member
Shares that in the aggregate for all transfers made pursuant to this subsection
by any or all of the Members is equal to or less than the number of Excepted
Shares, provided that each such sale is exempt from the registration
requirements of the Securities Act and is effected through unsolicited broker
transactions within the meaning of paragraph (g) and the first sentence of
paragraph (f) of Rule 144 of the General Rules and Regulations under the
Securities Act,  as in effect on the date of this Agreement. Prior to the
consummation of a disposition of any Member Shares in accordance with this
Section 2.3(f), such Member Shares must be converted into shares of Low Vote
Stock of the corresponding series.  The number of any Member Shares disposed of
pursuant to this Section 2.3(f) shall be subtracted from the number of Excepted
Shares.  Upon the consummation of a disposition of 

                                       18
<PAGE>
 
Member Shares pursuant to this Section 2.3(f), the Magness Group Representative
shall deliver to the Company a written notice stating the number of Member
Shares so disposed of, identifying the Member or Members selling such Member
Shares and the number sold by each, and the aggregate number of Excepted Shares
which the Members of the Magness Group continues to beneficially own.
 
          (g) The Company agrees that if a Permitted Pledge of any Member Shares
is made and the lender forecloses or takes any other action to enforce the
security interest represented by such pledge and makes an irrevocable
commitment, in accordance with the definition of "Permitted Pledge" in Section
1.1 hereof, to convert such Member Shares into shares of Low Vote Stock on a
share-for-share basis, the Company shall permit such conversion and shall
reasonably cooperate with such lender in effecting such conversion as promptly
as reasonably practicable and shall comply with Section 6.4(b) of the
Stockholders Agreement.

 3.  Public Sale Election.

     3.1  Company Election.  (a)  Notwithstanding anything in Section 2.2(d) or
Section 2.3(b)(iii) to the contrary, but subject to Section 2.3(e), the Company
shall have the right to pay all or any portion of the Closing Date Amount or
Company Price, as applicable, in shares of Low Vote Stock in accordance with the
following procedures.  At least five (5) Business Days prior to the Closing
Date, the Company shall notify (the "Public Sale Notice") the Magness Group
Representative, on behalf of the Holder or each Transferor, as the case may be,
as to the portion of the Closing Date Amount or Company Price, as applicable, to
be paid in shares of Low Vote Stock (the "Public Sale Dollar Amount").  The
number of shares of Low Vote Stock (the "Resale Stock") deliverable to the
Underwriters pursuant to Section 3.2 shall be that number of shares which when
sold in accordance with Section 3.2 will reasonably be expected to yield
aggregate net proceeds collectively to all the Member(s) and Permitted
Transferee(s), if any, participating in the sale (collectively, the "Seller")
(after deduction of underwriting discounts and commissions and assuming the
payment by the Company of all other expenses of registration and sale of the
Resale Stock) of an aggregate amount equal to the Stock Proceeds Amount.

          (b) The term "Stock Proceeds Amount" shall mean the sum of  (i) Public
Sale Dollar Amount, plus (ii) interest on the Public Sale Dollar Amount,
accruing from and including the Closing Date to the date of payment pursuant to
Section 3.2, at a rate equal to the weighted average interest rate applicable as
of the Closing Date to that portion of the consolidated indebtedness of the
Company that bears interest at a floating interest rate.

          (c) Subject to the foregoing, the decision as to which series of Low
Vote Stock and the number of shares of each such series that will comprise the
Resale Stock shall be made by the Company at its discretion.  Such shares shall
be held by the Company on behalf of the Seller pending the Sales, and the
Company shall be authorized to deliver such shares to the Underwriters on such
Seller's behalf prior to the closing of the Sales.

                                       19
<PAGE>
 
      3.2 Public Sale.   (a)     On the Closing Date, the Company shall provide
an effective registration statement (the "Registration Statement") registering
under the Securities Act resales of the Resale Stock deliverable pursuant to
Section 3.1 having a maximum aggregate offering price (net of underwriting fee
and commissions) equal to the Stock Proceeds Amount.  Such Resale Stock shall be
sold (at the Company's discretion but in the form of one or more secondary
offerings on behalf of each Seller) under the Registration Statement during the
period of not more than 45 days following the Closing Date as specified by the
Company (the "Offering Period").  The Company may by notice to each Seller at
any time shorten the Offering Period, and in such event, the Offering Period as
referred to herein shall mean such shorter period.  All sales (the "Sales") of
the Resale Stock shall be made on behalf of each Seller by underwriters selected
by the Company (the "Underwriters") pursuant to one or more block trades,
underwritten offerings or otherwise, in each case as determined by the Company.
The actual net proceeds from the Sales (after deduction of underwriting
discounts and commissions) are referred to as the "Net Proceeds".  The Company
shall pay all expenses of registration and sale of the Resale Stock.

          (b) On the fifth Business Day following the termination of the
Offering Period, the Company shall deliver the Net Proceeds to the Magness Group
Representative, as agent for the Member(s) and Permitted Transferee(s), if any,
comprising the Seller, and if the Net Proceeds are less than the Stock Proceeds
Amount, the difference (the "Difference") shall be paid by the Company in cash
on such date to the Magness Group Representative, as such agent.  The Company
may elect to pay some or all of the Difference prior to such date and in such
event the interest component of the portion of the Difference so paid early
shall be calculated with respect to such earlier payment date.  If the Net
Proceeds exceed the Stock Proceeds Amount, the Company may retain the excess.

          (c) The Company shall indemnify the Seller and the Underwriters in
respect of the Sales to the same extent as the Company would indemnify the
Holder and the Underwriters as provided in the Registration Rights Agreement,
but the Sales shall not be deemed to have been made pursuant to the Registration
Rights Agreement.

          (d) Each Seller shall be required to cooperate with the Company in
connection with the Registration Statement and the Sales (including, without
limitation, by executing and delivering underwriting and other documents and
instruments, taking actions and providing information) as shall be reasonably
requested by the Company in connection therewith.

 4.  Closing Matters.

      4.1 Closing Date.  The consummation of the purchase and sale of (i) the
Subject Shares following the exercise of the Call Right pursuant to Section 2.2
or (ii) the Offered Shares following the exercise of the Call Right pursuant to
Section 2.3 (in each case, a "Closing") shall be held at 10:00 a.m. local time
on, respectively, (x) the 155th day following the Exercise Date, or (y) the 60th
day following the date the Election Notice is given or (z) such other date and
at such other time as the Holder or the Transferor and the Company may agree

Date").  The Closing shall take place at the principal 

                                       20

     4.2  Closing Deliveries.  At the Closing, the Company shall pay to the
Magness Group Representative, as agent for the Member(s) and Permitted
Transferee(s), if any, comprising the Seller (i) any portion of the Closing Date
Amount or Company Price, as applicable, that was required to be paid in cash in
the manner provided in Section 2.2(f) or Section 2.3(b)(iii), as and if
applicable, (ii) deliver certificate(s) registered in the name of each Seller
for the number of shares of Low Vote Stock required to be delivered in payment
of the Gross Stock Value portion of the Gross Purchase Price, and (iii) if the
Company has elected to pay any or all of the Closing Date Amount or Company
Price, as applicable, in shares of Low Vote Stock pursuant to Section 3.1,
deliver the Registration Statement conforming to the requirements of Section
3.2.  At the Closing, each of the Member(s) and Permitted Transferee(s), if any,
participating in the sale shall be required, as a condition to receiving
payment, to deliver to the Company (i) a stock certificate or certificates, duly
endorsed for transfer or in blank, representing such Person's Subject Shares or
Offered Shares, as applicable, (ii) if applicable, copies of Letters
Testamentary or other documentation evidencing the authority of such Person to
transfer any of the Subject Shares that are evidenced by certificates registered
in the name of a Person other than such Seller, (iii) a certificate, executed by
or on behalf of such Person, in which such Person represents and warrants to the
Company that such Person has good title to the Subject Shares or Offered Shares,
as applicable, being sold by him, free and clear of any liens, claims, charges
or encumbrances and has the legal authority to consummate such sale and (iv)
such other certificates and documents as the Company may reasonably request.

 5.  Certain Representations, Warranties and Covenants.

warranties surviving the execution, delivery and performance of this Agreement):

          (a) Such party has the legal right and all requisite power and
authority to make and enter into this Agreement and to perform his or its
obligations hereunder and comply with the provisions hereof.  If such party is

Company has been duly authorized by all necessary action on its part.  This
Agreement has been duly executed and delivered by such party and constitutes the
valid and binding obligation of such party enforceable against him or it in
accordance with its terms except as enforcement may be limited by bankruptcy,
insolvency, moratorium or other similar laws affecting the rights of creditors
generally and except that the availability of equitable remedies, including
specific performance, is subject to the discretion of the court before which any
proceeding therefor may be brought;

          (b) The execution, delivery and performance of this Agreement by such
party, and the compliance by such party with the provisions hereof, do not and
will not (with or without notice or lapse of time, or both) conflict with, or
result in any violation of, or default under, or give 

                                       21

rise to any right of termination, cancellation or acceleration of any obligation
or to loss of a material benefit under, any loan or credit agreement, note,
bond, mortgage, indenture, lease or other agreement, instrument, permit,
concession, franchise, license, judgment, order, decree, statute, law,
ordinance, rule or regulation applicable to such party or any of his or its
properties or assets, other than any such conflicts, violations, defaults, or
other effects which individually or in the aggregate do not and will not
prevent, restrict or impede such party's performance of his or its obligations
under and compliance with the provisions of this Agreement. If such party is the
Company, the execution, delivery and performance of and compliance with this
Agreement by it do not and will not contravene its charter, by-laws or other
organizational document; and

          (c)  No consent, approval, order or authorization of, or registration,

delivery or performance of this Agreement by such party, except, with respect to
the exercise of certain rights granted hereunder, in connection with Federal and
state securities laws.

          5.2  General Covenants.   (a)   In the event that any sale of shares
pursuant to this Agreement would violate any rules or regulations of any
governmental or regulatory agency having jurisdiction or any other material law,
rule, regulation, order, judgment or decree applicable to the parties hereto
(including, with respect to the Company, its subsidiaries or any of the
Company's or such subsidiary's respective properties and assets), then each
party hereto hereby agrees (i) to cooperate with and assist the other in filing
such applications and giving such notices, (ii) to use reasonable efforts to
obtain, and to assist the other in obtaining, such consents, approvals and
waivers, and (iii) to take such other actions, including supplying all
information necessary for any filing, as any affected party may reasonably
request, all as and to the extent necessary or advisable so that the
consummation of such sale will not constitute or result in such a violation.

          (b)  Each party hereto hereby further agrees that he or it shall not
take any action or enter into any agreement or arrangement restricting or
limiting his or its ability timely and fully to perform all his or its
obligations under this Agreement.  The grant by the Members of the Magness Group
of the voting rights and proxy provided for in Article II of the Stockholders
Agreement and the exercise of such rights and by this use of such proxy
agreement is not intended to be prohibited or otherwise affected.
 
 6.  Stockholder's Covenant Relating to a Sale of Company.

     6.1  Limitation on Size of Premium.  (a)  In connection with any proposed
Sale of the Company, each Member agrees not to negotiate for or require as a
term of such transaction or as a condition to his agreement to vote therefor
that either (i) the holders of High Vote Stock receive for such High Vote Stock
or (ii) any Member or any Related Party or Affiliate of any Member receives for
the shares of High Vote Stock or Common Stock beneficially owned by any of them,
consideration the value of which on a per share basis exceeds the value per
share payable to (x) holders of shares of Low Vote Stock into which such High
Vote Stock is convertible or (y) holders 

                                       22
<PAGE>
 
of Common Stock other than any Member or any Related Party or Affiliate of any
Member, in either case by more than ten percent (10%) (a "Prohibited Premium").
For the purposes of computing the existence of a Prohibited Premium, if any
noncash consideration to be received by any holders of Common Stock in any
proposed Sale of the Company is the same for both (A) (i) the holders of High
Vote Stock or (ii) any Member or any Related Party or Affiliate of any Member,
as applicable, and (B) (x) holders of shares of Low Vote Stock into which such
High Vote Stock is convertible or (y) holders of Common Stock other than any
Member or any Related Party or Affiliate of any Member, as applicable, a
Prohibited Premium shall be deemed to exist if the ratio of such noncash
consideration given to the Persons listed in (A) above exceeds the amount of
such noncash consideration given to the Persons listed in (B) above by more than
ten percent (10%). If different forms of noncash consideration are to be given
to the Persons listed in (A) above than to the Persons listed in (B) above, and
there is any disagreement between the Independent Committee and any such Person
or the Magness Group Representative as to the value of any such consideration
for the purposes of determining if there is a Prohibited Premium, then the
noncash consideration shall be valued by using the appraisal procedures set
forth in Section 2.3(c).

          (b)  If a proposed Sale of the Company containing a Prohibited Premium
is submitted to the stockholders of the Company for a vote, each Member agrees
that he will vote all of his Member Shares, and any other shares of voting stock
entitled to vote on such proposal beneficially owned by him, against such
proposal.

 7.    Miscellaneous.
 
     7.1  Actions by Magness Group.  (a)  Any notice, consent, approval or other
decision by or on behalf of the Magness Group or any Member or Members required
or permitted by this Agreement shall be effective if expressed in a writing
which is either executed by the Magness Group Representative or by all such
Member(s), and in either such case the parties to this Agreement may assume that
such the Magness Group Representative or such Member(s), as the case may be, has
or have the power and authority to do so and may rely conclusively on such
writing as expressing the action of the Magness Group or such Member or Members,
as the case may be.
 
     (b)  The Magness Group may designate any of its members as the Magness
Group Representative by written notice of such designation (and containing such

Person serving as the Magness Group Representative, the Magness Group shall
promptly designate a successor.  Pending such designation, each party to this
Agreement shall be entitled to treat as the Magness Group Representative the
member of the Magness Group who holds of record the greatest number of shares of
High Vote Stock.

     7.3  Binding Effect; Assignability; Entire Agreement; Legends  (a)  Except
as expressly provided herein, no party hereto may assign its rights or delegate
its obligations hereunder without the prior written consent of the other parties
hereto, except that the Company may assign its rights and delegate its
obligations without such consent to any successor corporation by operation of
law. Any assignment or delegation in contravention of this Agreement shall be
void and shall not relieve the assigning or delegating party of any obligation
hereunder. This Agreement and all of the provisions hereof shall be binding upon
and inure to the benefit of the parties hereto and their respective successors
and permitted assigns.

          (b)  This Agreement sets forth the entire agreement and understanding
between the parties as to the subject matter hereof and merges and supersedes
all prior discussions, agreements and understandings of any and every nature
among them with respect to such subject matter.  For the sake of certainty, the
parties specifically acknowledge that this Agreement is not intended to merge,
supersede or alter the provisions of (i) the Stockholders Agreement or (ii) any
provision of the Agreement, effective as of January 5, 1998 and titled
"AGREEMENT RE: SETTLEMENT OF MAGNESS ESTATE LITIGATION" among certain parties to
such Stockholders' Agreement and certain other Persons, as it may be amended
from time to time (the "Settlement Agreement"), other than numbered paragraph 10
thereof or (iii) any separate agreement, release or instrument granted, entered
into or delivered pursuant to such Settlement Agreement.

          (c)  Except as expressly set forth herein, none of the provisions of
this Agreement shall inure to the benefit of or be enforceable by any Person not
a party hereto.

          (d)  The provisions of Section 6.4 of the Stockholders Agreement are
hereby incorporated by reference, with the same force and effect as if set forth
at this place.

     7.4  Amendments and Waivers.   Subject to Section 7.13 hereof, the
provisions of this Agreement, including the provisions of this sentence, may not
be amended, modified or supplemented, and waivers of or consents to departures
from the provisions hereof may not be given unless approved in writing by the
Company and the Magness Group Representative.

     7.5  Governing Law.   This Agreement shall be governed by and construed in

                                VOTING OF SHARES
                                ----------------

      Section 2.1        Board Representation of Magness Group.   (a)  Subject
                         -------------------------------------                
to subsections 2.1(b), 2.1(c) and 2.1(d), in each election of directors of any
Company (whether at a meeting or by written consent in lieu of a meeting or
otherwise), JCM (or his legal representative, if he is incapacitated) will vote
or cause to be voted all High Vote Shares Beneficially Owned by him for the
election as one of the directors of such Company (the "Designated Director" of
such Company) either Kim Magness or another individual designated by the Magness
Group, provided that the following requirements are satisfied:

          (i)  Kim Magness will be the Magness Group's initial nominee as the
               Designated Director of TCI.  Not later than the tenth day after
               the Magness Group Representative receives written notice from JCM
               or such Company of the intended mailing (at any time after the
               date of this Agreement) of notice to stockholders of any Company
               of a meeting for the purpose of electing directors, the Magness
               Group Representative shall notify each of JCM, TCI and such
               Company in writing of the name of the individual designated by
               the Magness Group as their nominee as Designated Director.  If no
               such notice is given on a timely basis, JCM, TCI and such Company
               may for all purposes treat the then incumbent individual, if any,
               then serving as the Designated Director of such Company as the
               nominee designated by the Magness Group for election as
               Designated Director in such election.

          (ii) No Company nor JCM shall be required to nominate, appoint, elect
               reappoint, reelect or vote for the election, appointment,
               reelection or reappointment of any individual serving or
               nominated to serve as the Designated Director of any Company if,
               in the good faith judgment of the Board of Directors of such
               Company or JCM, (A) there has been any action or omission by such
               Person or any other event or circumstance affecting or existing
               with respect to such Person that would constitute cause for
               removal of a director of a business corporation under the laws of
               the jurisdiction of incorporation of such Company, (B) such
               individual does not, at the time of nomination and at the time of
               election or appointment, meet all eligibility requirements under
               applicable law and of NASDAQ or any stock exchange on which
               securities of such Company are listed or quoted or (C) such
               individual is directly or indirectly a director, officer or
               Affiliate of any Entity that directly or indirectly competes with
               any significant business of any Company or any Affiliate of any
               Company.  JCM or such Company shall give the Magness Group
               Representative prompt written notice of any 

                                       2
<PAGE>
 
               determination by him or it that any nominee of the Magness Group
               is disqualified under the terms of this clause (ii), and the
               Magness Group Representative may, within five Business Days after
               such notice is given, nominate a substitute who meets the
               requirements of this clause (ii). For purposes of this clause
               (ii) the fact that Kim Magness or another nominee as a Designated
               Director commenced the actions and proceedings referred to in the
               Settlement Agreement shall not itself be a disqualification of
               any of the kinds referred to above in this clause.

        (iii)  If any individual proposed by the Magness Group Representative
               to serve as the Designated Director of any Company who satisfies
               the requirements set forth in clause (ii) above is not nominated
               by the Board of Directors of that Company for election or is not
               appointed to fill a vacancy contemplated by subsection 2.1(b),
               but such individual is nominated on a timely basis by the Magness
               Group Representative in a manner permitted by applicable law and
               the certificate of incorporation and by-laws of that Company, JCM
               shall (subject to the terms and conditions set forth in this
               Section 2.1) vote all High Vote Shares Beneficially Owned by him
               for the election of such individual as one of the directors of
               such Company.

     (b)  Subject to subsections 2.1(a), 2.1(c) and 2.1(d), in the event of any
vacancy in the office of Designated Director of any Company results from the
resignation, death or removal of the incumbent Designated Director and if the
Board of Directors of that Company has the legal authority to fill the vacancy
for the balance of that incumbent's term with a substitute appointed by such
Board, JCM and the Magness Group Representative will use their respective best
efforts to cause such Board to exercise that authority and fill the vacancy with
an individual designated by the Magness Group Representative in a written notice
delivered to Malone not later than three Business Days after such vacancy
occurs.

     (c)  For the sake of certainty, subsections 2.1(a) and 2.1(b) are intended
to create obligations or rights with respect to only one Designated Director for
each Company.  Without limiting the generality of the foregoing sentence, in the
event that the Board of Directors of any Company is or shall be classified,
neither JCM nor any Company will be obligated to nominate, elect, appoint or
vote for more than one Designated Director for the entire Board of Directors,
and the requirements of subsections 2.1(a) and 2.1(b) will apply only to the
election of the members of the class that includes such sole Designated
Director.

     (d)  The parties acknowledge and agree that the directors of each Company
are or may be subject to fiduciary duties to stockholders or other security
holders under mandatory provisions of law.  In addition, although this Section
2.1 is intended (subject to its express terms and conditions) to bind JCM to
vote High Vote Shares Beneficially Owned by him if, as and when required by this

                                       3
<PAGE>
 
Agreement, the parties recognize and agree that nothing contained in this
Agreement constitutes a guarantee or other assurance that any nominee of the
Magness Group as the Designated Director of a Company will be elected or remain
in office.

          Section 2.2    Voting on Other Matters.
                         ----------------------- 

     (a)  In the case of any matter (other than the election or appointment of a
Designated Director subject to Section 2.1) submitted or to be submitted to a
vote or the written consent of, or other action by, the holders of any class or
series of High Vote Shares of any Company at a time when any member of the
Magness Group and any member of the Malone Group Beneficially Own any such High
Vote Shares, JCM, on behalf of the Malone Group, and the Magness Group
Representative, on behalf of the Magness Group, will use their reasonable
efforts to consult with each other in advance concerning the manner in which
each Group will vote or otherwise act with respect to such matter.   Subject to
the next sentence, if such Persons are unable to reach unanimous agreement
concerning the manner in which each Group will vote or otherwise act with
respect to such matter, each member of the Malone Group and each Member of the
Magness Group will vote or otherwise act with respect to such matter in the
manner directed by JCM.  If JCM shall fail in any material respect to vote for
any qualified nominee of the Magness Group as Designated Director for any
Company if, as and when required by Section 2.1 or if the directors of any
Company fail to fill any vacancy referred to in Section 2.1(b) with the
substitute proposed as provided therein, then unless such failure is the result
of the failure of such nominee to agree to serve or otherwise caused by any act
or omission of such nominee or any member of the Magness Group, the members of
the Magness Group shall have complete discretion in determining the manner in
which they will vote their High Vote Shares in such Company with respect to any
such matter that is submitted to the holders of such High Vote Shares (and the
rights and powers granted to JCM with respect to such High Vote Shares in
subsection 2.2(b) shall be suspended) unless and until JCM or such directors
shall correct such failure by voting for or appointing the Magness Group's
nominee on a subsequent occasion or otherwise.

     (b)  In furtherance of the purposes and intent of this Section, each member
of the Magness Group hereby grants to JCM or to his designee(s), with full power
of substitution, an irrevocable proxy to vote, in person or by proxy and at any
annual or special meeting of stockholders (or adjournment thereof), by written
consent or otherwise, all High Vote Shares in each and every Company (whether
now existing or hereafter created) now or at any time hereafter Beneficially
Owned by such member.  Each member of the Magness Group affirms and agrees that
such proxy is coupled with an interest and, to the maximum extent permitted by
applicable law, is irrevocable and shall survive the disability, incapacity,
bankruptcy, insolvency, dissolution, liquidation or death of such member and
shall extend to such member's heirs, successors, assigns and legal
representatives.  Each member of the Magness Group hereby ratifies and confirms
all that JCM or his designee(s) or substitute(s) may lawfully do or cause to be
done by virtue of such proxy.  Each member of the Magness Group agrees to
execute any separate form of proxy, written consent to 

                                       4
<PAGE>
 
action or other instrument that JCM may at any time and from time to time
reasonably request in order to evidence such member's proxy and to carry out the
purposes and intent of this Section.

      Section 2.3   Other Actions.  Each party to this Agreement agrees that
                    -------------                                           
whenever this Agreement requires any action on the part of any party in his
capacity as a holder of any High Vote Shares of any Company, such party will,
solely in such capacity, take all steps reasonably necessary to make such action
effective, including attending and voting at any meeting of stockholders (or any
adjournment thereof) all shares of High Vote Shares held by such party in favor
of such action, or executing or causing to be executed, as promptly as
practicable, a consent in writing to the taking of such action.

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

     (a) Subject to the terms and provisions of this Article III, if JCM shall
hereafter acquire, and shall determine to exercise, any right (an "Acquisition
Right") to acquire any Equity Securities or any Rights to acquire any Equity
Securities of any Covered Issuer from such Covered Issuer or any third-party
which is not a Related Party or Affiliate of JCM (collectively, "Subject
Securities"), other than an Exempt Acquisition Right, JCM shall promptly notify
the Magness Group Representative of such Acquisition Right and shall either
offer or cause such Covered Issuer or third party to offer to the Magness Group
(a "Participation Offer"), in the manner hereinafter set forth, the opportunity
to acquire, collectively and on economic terms on a per share or per security
basis that are substantially identical to those offered to JCM, up to, but in no
event more than the number or amount (as appropriate) of Subject Securities
equal to the product obtained by multiplying the total number or amount (as
appropriate) of such Subject Securities as to which JCM exercises such
Acquisition Right by a fraction the numerator of which is the total number of
High Vote Shares Beneficially Owned by any and all members of the Magness Group
as of the date the applicable Participation Notice is given and the denominator
of which is the sum of (i) the total number of High Vote Shares Beneficially
Owned by any and all members of the Magness Group as of such date plus (ii) the
total number of High Vote Shares Beneficially Owned by any and all members of
the Malone Group as of such date.  If, when and to the extent the options to
acquire shares of TCI capital stock created in favor of JCM by the June 16 Stock
Transaction (as defined in the Settlement Agreement) are exercised, they shall
collectively constitute an Acquisition Right subject to this Article III, but
the number of shares which are Subject Shares with respect to such Acquisition
Right shall be reduced by the number of TCI Low Vote Shares that the Betsy
Estate has the right to exchange pursuant to numbered paragraph 24 of the
Settlement Agreement.  The term Acquisition Right includes any right of JCM (if
and to the extent exercised) to acquire Equity Securities of a Covered Issuer in
connection with a "going private" transaction involving that Covered Issuer.

     (b) The Magness Group may exercise in whole or in part its rights under
Section 3.1(a) with respect to any Acquisition Right.  Subject to the terms and
conditions set forth Section 3.2, the Subject Securities that the Magness Group
shall be entitled to acquire with respect to any Participation Offer may be
allocated among the members of the Magness Group in any manner in which they
agree among themselves.  Without limiting the generality of Section 6.2, the
members of the Malone Group and each Covered Issuer shall be entitled to rely
exclusively and conclusively on information provided by the Magness Group
Representative as to any such allocation or other matters in connection with the
exercise of the rights of the Magness Group under this Article III and shall
not, in any event, have any liability to any member of the Magness Group as a
result of such reliance.

     Section 3.2        Notices of Acceptance and Other Procedural Matters.
                        -------------------------------------------------- 

     (a)  Unless JCM and the Magness Group Representative otherwise agree, in
order to accept a Participation Offer, the Magness Group members must, on or
before the date of execution and delivery by JCM (or any of his Controlled
Affiliates or designees), execute and deliver to the Covered Issuer or the
third-party referred to in Section 3.1(a), as the case may be, all of the
agreements, instruments and other documents required to be executed and
delivered by JCM (or any of his Affiliates or designees) in connection with the
exercise of the relevant Acquisition Right; provided that the representations,
                                            --------                          
warranties, covenants, conditions and other terms and provisions thereof are
substantially identical on a per share or per security basis as the terms and
conditions of any such agreements, instruments and other documents required to
be executed and delivered by JCM (or any of his Controlled Affiliates or
designees), subject to any variations customary in similar transactions to
reflect differences in the sizes of participations and other differences in the
particular circumstances of such participants.

     (b) In order to accept any opportunity presented to the Magness Group by
JCM pursuant to Section 3.1, the Magness Group Representative must give a
written notice of acceptance to JCM, not later than 21 days after JCM gives the
Magness Group Representative written notice of such opportunity.  If the Magness
Group does not duly elect on a timely basis to accept any Participation Offer
for all or any portion of its allocated number or amount of the Subject
Securities, or in the event any unexcused default by any member of the Magness
Group in purchasing all of such Subject Securities if, as and when required by
the terms of the agreements, instruments and documents executed and delivered
pursuant to subsection 3.2(a), then in addition to any other rights or remedies
otherwise available to the Covered Issuer, any third-party offeror, JCM or any
other Person participating in that or a related transaction, (i) the Covered
Issuer or third-party referred to in Section 3.1(a), as the case may be, may
sell or otherwise dispose of the Subject Securities that the Magness Group does
not elect to acquire or fails to purchase to JCM or any other Person and on any
terms selected by it in its absolute discretion, without being required to re-
offer such Subject Securities to the Magness Group, (ii) JCM shall be relieved
of all further obligations or liabilities to the Magness Group pursuant to this
Article III with respect to that Acquisition Right and (iii) in 

                                       6
<PAGE>
 
the case of any such unexcused default by any member of the Magness Group, JCM
also will be relieved of all further obligations or liabilities to such
defaulting member with respect to any future Acquisition Right.

     (c)  Without limiting the generality of subsection 3.2 (a), (i) if an
Acquisition Right is in conjunction with the borrowing of money from JCM or any
of his Affiliates or Related Parties, then no member of the Magness Group shall
have any right to participate therein unless such member (or its Affiliates)
purchases or participates, on a pro rata basis, in the related financing on the
                                --- ----                                       
same basis as JCM or any of his Affiliates or Related Parties or (ii) if an
Acquisition Right is part of a larger transaction or one of a series of related
transactions pursuant to which JCM or any of his Affiliates or Related Parties
have agreed (or are required to agree in order to exercise such Acquisition
Right) to provide consideration or make commitments or undertakings beyond
simply paying the purchase price for the Equity Securities that are subject to
such Acquisition Right, then no member of the Magness Group shall have any right
to participate therein unless such member (or its Affiliates) agrees to and has
the ability to provide the same consideration, make the same commitments and
undertakings and, in general, consummate such larger transaction or series of
related transactions on substantially the same per share or per security basis
as JCM or any of this Affiliates or Related Parties.

                                   ARTICLE IV

                        TAG-ALONG AND DRAG-ALONG RIGHTS
                        -------------------------------

     Section 4.1   Tag-Along Right.
                   --------------- 

 
     (a) Subject to the terms and conditions set forth in this Section 4.1, if,
at any time after the date of this Agreement, any member of the Malone Group (a
"Selling Stockholder") proposes to Transfer to any Person(s), including TCI or
any of its Affiliates (the "Prospective Purchaser"), any TCI High Vote Shares of
any class or series, other than in an Exempt Transfer, such Selling Stockholder
shall not consummate or enter into a binding agreement to consummate such sale
unless the Prospective Purchaser, one or more members of the Malone Group, any
other Person or Persons designated by JCM or any combination of the foregoing
(in any such case, the "Buyers") shall offer to purchase TCI High Vote Shares of
the same class or series that were Beneficially Owned by any one or more members
of the Magness Group as of the date of the applicable Tag-Along Notice and that
at all times thereafter continue to be owned by one or more members of the
Magness Group until sold pursuant to this Section ("Eligible Shares").  In no
event will Eligible Shares include any TCI High Vote Shares the Beneficial
Ownership of which is acquired after the date the Tag-Along Notice is given or
which cease to be Beneficially Owned by a member of the Magness Group at any
time prior to the sale and purchase of such TCI High Vote Shares pursuant to
this Section 4.1.

                                       7
<PAGE>
 
     (b) Prior to any sale by any Selling Stockholder subject to subsection
4.1(a), such Selling Stockholder or JCM shall give the Magness Group
Representative a written notice (the "Tag-Along Notice") that shall set forth:
(i) the number of TCI High Vote Shares subject to the proposed sale; (ii) the
name and address of the Prospective Purchaser; and (iii) the proposed amount and
kind(s) of consideration (including a good faith estimate of the value of any
non-cash consideration) and terms and conditions of payment offered by the
Prospective Purchaser.  The Magness Group may exercise its tag-along right under
this Section 4.1 by delivery to JCM, within 21 days after the date the
applicable Seller's Notice is given, of a written notice (the "Tag-Along
Exercise Notice") signed by the Magness Group Representative and stating the
aggregate number of Eligible Shares that the Magness Group proposes to include
in the proposed sale (which number may not exceed the number determined under
subsection (c) of this Section 4.1)(the "Tag-Along Shares"), as well as the name
of each member of the Magness Group who will participate in such sale and the
number of Tag-Along Shares allocated to each such participating member.  If no
Tag-Along Exercise Notice is received during such ten-day period or if any one
or more members of the Magness Group otherwise fail to comply with the
requirements set forth in this Section 4.1, each Selling Stockholder will have
the right for 180 days thereafter to effect or enter into a binding agreement to
effect the proposed sale, provided that the terms and conditions relating to the
amount, kind and payment of consideration are not materially more favorable to
the Selling Stockholder than those stated in the Tag-Along Notice (or any
subsequent communication by JCM with the Magness Group or the Magness Group
Representative).  Notwithstanding the foregoing, if a proposed sale is subject
to the receipt of any regulatory approval or expiration of any waiting period
under applicable law, the time period during which such sale may be consummated
or such binding agreement may be entered into shall be extended until the
expiration of five Business Days after all such approvals have been received and
all such waiting periods have expired, but in no event shall such time period
exceed an additional 180 days.

     (c) The aggregate number of Eligible Shares of any class or series as to
which the Magness Group, collectively, shall be entitled to exercise the tag-
along right under this Section 4.1 with respect to any transaction referenced in
any Tag-Along Notice shall be up to, but in no event more than the product
obtained by multiplying the total number of TCI High Vote Shares of such class
or series that the Prospective Purchaser is willing to purchase from the members
of the Malone Group and the members of the Magness Group, collectively, by a
fraction the numerator of which is the total number of Eligible Shares of that
class or series Beneficially Owned by any and all members of the Magness Group
as of the date the applicable Seller's Notice is given and the denominator of
which is the sum of (i) the total number of Eligible Shares of that class or
series Beneficially Owned by any and all members of the Magness Group as of such
date plus (ii) the total number of TCI High Vote Shares of that class or series
Beneficially Owned by any and all members of the Malone Group as of such date.
Subject to the terms and conditions set forth in this Section 4.1, the total
number of Tag-Along Shares that the Magness Group shall be entitled to sell with
respect to any transaction referenced in any Tag-Along Notice may be allocated
among the members of the Magness Group in any manner in which they agree among
themselves.  Without limiting the 

                                       8
<PAGE>
 
generality of Section 6.2 the members of the Malone Group and the Prospective
Purchaser shall be entitled to rely exclusively and conclusively on information
provided by the Magness Group Representative as to any such allocation or other
matters in connection with the exercise of the rights of the Magness Group under
this Section 4.1 and shall not, in any event, have any liability to any member
of the Magness Group as a result of such reliance. The Magness Group shall be
entitled to exercise the tag-along right under this Section 4.1 only with
respect to issued and outstanding Tag-Along Shares held by participating members
of the Magness Group and shall not be entitled to exercise such right with
respect to any Eligible Shares underlying any unexercised Rights.

     (d)  Any purchase of Tag-Along Shares from the Magness Group pursuant to
this Section 4.1 shall be on terms and conditions relating to the kind, amount
and terms of payment of consideration for such Tag-Along Shares that are
substantially identical, on a per share or per security basis, to the terms and
conditions offered by the Prospective Purchaser to the Selling Stockholder.

     (e)  Any member of the Magness Group who desires to exercise its rights
under this Section 4.1 must (i) agree and be able to sell to the Buyers good and
marketable title to the Tag-Along Shares proposed to be sold, free and clear of
all liens and restrictions (other than any applicable restrictions on transfer
of such Tag-Along Shares by the Buyers under the federal securities laws), (ii)
satisfy, as of the time of the closing of the sale by the Selling Stockholder to
the Prospective Purchaser, any and all conditions to the sale by such member to
the Buyers that are substantially identical to those required to be satisfied by
the Selling Stockholder (other than any conditions that relate uniquely to the
Selling Stockholder) and (iii) make or provide to or for the benefit of the
Buyers representations, warranties, covenants and indemnities that are
substantially identical to those required to be made or provided by the Selling
Stockholder to or for the benefit of the Prospective Purchaser (other than any
representations and warranties that relate uniquely to the Selling Stockholder).

     (f)  Any amendments, modifications or waivers of the terms and conditions
on which the Selling Stockholder proposes or agrees to sell TCI High Vote Shares
to a Prospective Purchaser occurring after the conclusion of the ten-day period
referred to in subsection 4.1(b) shall not be deemed to require that such
transaction be re-offered to the Magness Group unless the effect of such
amendment, modification or waiver is to make the terms of such sale materially
more favorable to the Selling Stockholder than the terms set forth in the last
Tag-Along Notice delivered prior to the conclusion of such period, and no
increase or decrease in the market value of the consideration offered in any
such sale shall constitute an amendment, modification or waiver of any provision
of such sale requiring further compliance with the provisions of this Section
4.1.

     (g)  Subject to the terms and conditions contained in any agreement entered
into with the Buyers, and without limiting any other rights or remedies that any
Prospective Purchaser, Buyer or member of the Malone Group may have, in the
event that any member or members of the Magness Group fail to satisfy on a
timely basis any condition to consummation of the purchase of any Tag-

                                       9
<PAGE>
 
Along Shares by the Buyers, the Tag-Along Shares proposed to be sold by such
member or members of the Magness Group shall be excluded from such sale, and the
members of the Malone Group shall be entitled to substitute additional TCI High
Vote Shares owned by them in place of such excluded Tag-Along Shares.
 
     (h)  Nothing contained in this Section shall obligate JCM, any Selling
Stockholder, any Prospective Purchaser or any Buyer to consummate any sale
contemplated by this Section 4.1 and (subject to the terms of any binding
definitive sale agreement which may be entered into) such proposed sale may be
abandoned by such Persons at any time, whether before or after the giving of any
Tag-Along Notice or Tag-Along Exercise Notice.

     (i)  If the decision of JCM to pursue any sale that otherwise would be
subject to this Section 4.1 is a result of any judgment, order or decree
requiring a sale or other Disposition by any or all members of the Malone Group
of any of its or their High Vote Shares of or other interests in such Company or
imposing penalties or sanctions upon any member of the Malone Group, any Company
or any Affiliate of either if such interests are maintained and if, in the good
faith opinion of JCM, compliance with the time periods, procedures or other
provisions of this Section 4.1 would be inconsistent with such judgment, order
or decree or with avoiding any such penalties or sanctions, then JCM may, with
the consent of the Magness Group Representative (which consent shall not be
withheld unreasonably), modify or forego strict compliance with such time
periods, procedures and provisions so long as the essential purpose and intent
of this Section 4.1 are preserved.

     Section 4.2    Drag-Along Right.
                    ---------------- 

     (a)  For purposes of this Section 4.2, the term "Approved Sale" shall mean
any proposal made or approved by JCM to Transfer to any Person(s), including any
Company or any Affiliate of any Company (a "Drag-Along Purchaser"), in one
transaction or a series of transactions, either all or substantially all of the
High Vote Shares of any Company Beneficially Owned by him, or substantially all
of the business or assets of any Company, in either case regardless of whether
such transaction or series of transactions take the form of or include a merger
or consolidation, a sale of all or substantially all of assets of such Company,
a sale of outstanding capital stock or another type of transaction.

     (b)  If JCM at any time proposes an Approved Sale, the members of the
Magness Group (the "Other Stockholders") will, subject to the terms and
conditions set forth in this Section 4.2, consent to, vote for, participate in
and raise no objections against such Approved Sale and will take all reasonable
actions in connection with the consummation of such Approved Sale requested by
JCM or the Drag-Along Purchaser.  If the Approved Sale is structured as a sale
of outstanding High Vote Shares of any class or series (an "Approved Stock
Sale"), each such Other Stockholder must elect to either (i) convert into Low
Vote Shares of the issuer all High Vote Shares of each affected class or series
then owned by such Other Stockholder or thereafter acquired by such Other
Stockholder 

                                       10
<PAGE>
 
upon any exercise of any Rights to acquire any High Vote Shares or (ii) agree to
sell or otherwise Dispose of all of the High Vote Shares of such class or series
Beneficially Owned by such Other Stockholder (including any such High Vote
Shares issuable upon exercise of any unexercised Rights held by such Other
Stockholder) on terms and conditions substantially identical, on a per share or
per security basis, to those applicable to the High Vote Shares of such class or
series Beneficially Owned by JCM. If any such Other Stockholder elects the
option described in clause (ii) of the immediately preceding sentence, the
purchase price payable for any High Vote Shares issuable upon exercise of any
unexercised Rights held by such Other Stockholder shall be reduced by the amount
of cash or the fair market value of any other consideration that would be
payable by a holder thereof upon exercise.

     (c) Without limiting the generality of subsection 4.2(b), if any Approved
Sale is structured as a sale of stock, each Other Stockholder will, subject to
the terms and conditions of this Section 4.2, enter into the same form of sale
agreement as the members of the Malone Group participating in such sale, and
provide the purchaser with such representations and warranties as to such Other
Stockholder's power and authority to sell and its ownership of the securities
being sold by such Other Stockholder to such purchaser, with such covenants and
with such indemnification for breach of such representations, warranties and
covenants as are customarily given by selling stockholders in similar
transactions.  In the event any dispute arises over whether the form of any such
requested representations, warranties, covenants or indemnities is considered
customary in such transactions, such dispute shall promptly be submitted to a
law firm reasonably satisfactory to the Magness Group Representative and JCM,
whose determination shall be binding upon the parties.

     (d)  Nothing contained in this Section 4.2 shall obligate JCM, any member
of the Malone Group, any Company or any Drag-Along Purchaser to consummate any
proposed Approved Sale and, subject to the terms of any binding definitive
agreement for an Approved Sale which may be entered into, any such proposed
Approved Sale may be abandoned by any or all of such Persons at any time.
 
     (e)  If the decision of JCM to pursue an Approved Sale with respect to any
Company is a result of any judgment, order or decree requiring a sale or other
Disposition by any or all members of the Malone Group of its or their interests
in such Company or imposing penalties or sanctions upon any member of the Malone
Group, any Company or any Affiliate of either if such interests are maintained
and if, in the good faith opinion of JCM compliance with the time periods,
procedures or other provisions of this Section 4.2 would be inconsistent with
such judgment, order or decree or with avoiding any such penalties or sanctions,
then JCM may, with the consent of the Magness Group Representative (which
consent shall not be withheld unreasonably), modify or forego strict compliance
with such time periods, procedures and provisions so long as the essential
purpose and intent of this Section 4.2 are preserved.

     Section 5.1.   Representations and Warranties.  Each party to this
                    ------------------------------                     
Agreement represents and warrants to each other party that:

     (a)  Such party has the legal right and capacity, and all requisite power
and authority, to make and enter into this Agreement and to perform its
obligations hereunder and to comply with the provisions hereof.  The execution,
delivery and performance of this Agreement by such party has been duly
authorized by all necessary action on the part of such party.  This Agreement
has been duly executed and delivered by such party and constitutes the valid and
binding obligation of such party enforceable against it in accordance with its
terms, except as such enforcement may be limited by applicable bankruptcy,
insolvency, moratorium or other similar laws affecting the rights of creditors
generally and except that the availability of equitable remedies, including
specific performance, is subject to the discretion of the court before which any
proceeding therefor may be brought.

     (b)  The execution, delivery and performance of this Agreement by such
party, and the compliance by such party with the provisions hereof, do not and
will not (with or without notice or lapse of time, or both) conflict with, or
result in any violation of, or default under, or give rise to any right of
termination, cancellation or acceleration of any obligation or the loss of a
material benefit under, any loan or credit agreement, note, bond, mortgage,
indenture, lease or other agreement, instrument, permit, concession, franchise,
license, judgment, order, decree, statute, law, ordinance, rule or regulation
applicable to such party or any of its properties or assets, other than any such
conflicts, violations, defaults, or other effects which, individually or in the
aggregate, do not and will not prevent, restrict or impede such party's
performance of its obligations under and compliance with the provisions of this
Agreement.  If such party is an Entity, the execution, delivery and performance
of this Agreement by such party does not and will not contravene the charter,
bylaws or other organizational documents of such party.

                    ----------------------------------------------            
the BT Proxy, each member of the Magness Group or the Malone Group hereby
revokes all proxies and voting instructions, if any, with respect to any High
Vote Shares previously given by such Person and agrees that, except as permitted
by this Agreement, such member will not grant or give any other proxies or
voting instructions with respect to any High Vote Shares of any Company, enter
into any voting trust or other arrangement or agreement with respect to the
voting of any High Vote Shares of any Company now owned or hereafter acquired by
such Person, or agree, in any manner, to vote or dispose of any such High Vote
Shares of any Company in any manner other than as provided herein or in an
applicable Call Agreement.  No party, by entering into or amending any
agreement, any transfer of securities or assets or any other voluntary action,
avoid or seek to avoid the

<PAGE>
 
observance or performance of any of the terms of this Agreement or any Call
Agreement applicable to such party or any securities Beneficially Owned by such
party. The term "BT Proxy" means the voting rights granted to Bankers Trust
Company in the event of an exercise of remedies under a Permitted Pledge of
certain TCI High Vote Shares. The members of the Magness Group represent and
warrant to the Company and the members of the Magness Group that the BT Proxy
(including the terms and conditions of use of the BT Proxy) is in a form
customary for similar arm's length loan transactions between similarly situated
parties.
 
     Section 5.3.   Reasonable Efforts.  Each party to this Agreement shall use
                    ------------------                                         
reasonable efforts to take, or cause to be taken, all lawful actions, and to do,
or cause to be done, and to assist and cooperate with the other parties hereto
in doing, all lawful things, necessary, proper or advisable to carry out the
intent and purposes of this Agreement,  including (i) applying for, obtaining
and maintaining in effect all necessary actions or nonactions, waivers, consents
and approvals from Governmental Authorities and the making of all necessary

any) and the taking of all reasonable steps as may be necessary to obtain an
approval or waiver from, or to avoid an action or proceeding by, any
Governmental Authority, (ii) obtaining all other necessary consents, approvals
or waivers from third parties, (iii) defending any lawsuits or other legal
proceedings, whether judicial or administrative, challenging the legality or
validity of this Agreement or any part hereof, including seeking to have any
stay or temporary restraining order entered by any court or other Governmental
Authority vacated or reversed and (iv) executing and delivering  any additional
instruments necessary to carry out the intent and purposes of this Agreement;
provided, however, that nothing in this Section 5.2 shall require any such party
to agree to, approve or otherwise be bound by or satisfy any condition of any
kind referred to in Section 6.3 or to agree to any change to or waiver of the
terms of this Agreement or either Call Agreement or any waiver of any breach or
violation hereof or thereof or any rights or remedies with respect thereto.
Without limiting the generality of the foregoing, the parties will cooperate
with each other in seeking to structure any Approved Sale in the most tax-
efficient manner reasonably possible, consistently with the essential purposes
and intent of the applicable provisions of this Agreement.

     Section 5.4    Covenants Regarding Dispositions.
                    -------------------------------- 

     (a)  Except for Exempt Transfers, no member of the Malone Group or the
Magness Group shall sell, convey, exchange, pledge, hypothecate, give, donate,
distribute, assign or otherwise transfer, whether voluntarily, involuntarily,
directly or indirectly, any High Vote Shares of any Company, any Rights to
acquire any shares of or any voting or dispositive rights with respect to any
High Vote Shares of any Company or any other securities subject to this
Agreement or any Call Agreement, whether voluntary or involuntary and whether
directly or indirectly (any such action being referred to as a "Disposition"),
unless (i) such Disposition is made in accordance with all applicable provisions
of this Agreement and any applicable Call Agreement, and (ii) prior to
consummation of such Disposition each Person to whom any such Disposition is
made shall agree 

                                       13
<PAGE>
 
in writing to be bound by the provisions hereof applicable to members of the
same Group as the transferor; provided, however, that clause (ii) of this
sentence shall not apply to any Disposition that is an "Exempt Transfer" under
any provision of this Agreement or the applicable Call Agreement unless such
provision expressly requires that the transferee become a party hereto or
thereto. Any purported Disposition in violation of this Agreement shall be null
and void and of no force or effect, and each party agrees that the issuer of the
securities involved in any such Disposition may (and may direct each registrar
and transfer agent, if any, for such securities to) refuse to register or record
any such purported Disposition on its transfer and registration books and
records or to otherwise recognize such purported Disposition. For the sake of
certainty, the term "Disposition" includes any distribution or other Disposition
of any securities subject to this Section by the Bob Estate or the Betsy Estate
to any of the decedent's heirs or any other Person.

     (b)  If, notwithstanding the foregoing, any purported Disposition in
violation of this Agreement is made, then (in addition to any other rights or
remedies of the parties hereto) the provisions of this Agreement (including this
Section) shall apply to each transferee and all securities involved in such
Disposition as fully as if such transferee were a party to this Agreement and
bound by all of the provisions hereof that are or were applicable to the Person
making such Disposition, whether or not such transferee is required to or shall
formally agree to become a party to or be bound by this Agreement.

     (c)  If, notwithstanding the foregoing, any purported Disposition in
violation of this Agreement is held by a court of competent jurisdiction upon
entry of a final judgment or order to be effective, the parties intend that, to
the maximum extent permitted by applicable law, the provisions of this Agreement
(including this Section) shall apply to each transferee and all securities
involved in such Disposition as fully as if such transferee were a party to this
Agreement and bound by all of the provisions hereof which were applicable or
intended to be applicable to the Person making such Disposition, whether or not
such transferee is required to or shall formally agree to be a party hereto.
 
     Section 5.5.   Addition of Spin-Off Companies as Parties.  If any Spin-Off
                    -----------------------------------------                  
Company is created after the date of this Agreement, the parties will use their
respective reasonable efforts to cause such Spin-Off Company to agree in writing
to become a party to this Agreement and to be bound by the provisions hereof
applicable to Companies generally.  If such Spin-Off Company does not so agree,
the parties agree that the provisions of this Agreement that are applicable to
the High Vote Shares or other securities of Companies generally shall continue
to apply to the parties and the parties will use their good faith, reasonable
efforts to negotiate and agree upon any appropriate and equitable modifications
to such provisions reasonably required in order to carry out the intent and
purposes of such provisions as they relate to such Spin-Off Company, so far as
may be possible and reasonably practicable given the failure of such Spin-Off
Company to become a party to this Agreement.

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

     Section 6.1.   Terms Generally; Certain Rules of Construction.
                    ---------------------------------------------- 

     (a)  The definitions in Exhibit A shall apply equally to both the singular
and plural forms of the terms defined.  Whenever the context may require, any
pronoun shall include the corresponding masculine, feminine and neuter forms.
The word "or" is not exclusive and means "and/or."  The words "include",
"includes" and "including" shall be deemed to be followed by the phrase "without
limitation". The words "herein", "hereof" and "hereunder" and words of similar
import refer to this Agreement in its entirety and not to any part hereof unless
the context shall otherwise require.  All references herein to Sections,
subsections, Exhibits and Schedules shall be deemed references to and Sections
or subsections of, and Exhibits and Schedules to, this Agreement unless the
context shall otherwise require.  Unless otherwise expressly provided herein or
unless the context shall otherwise require, any references as of any time to any
agreement (including this Agreement) or other agreement, instrument or document
or to any statute or regulation or any specific section or other provision
thereof are to it as amended and supplemented through such time (and, in the
case of a statute or regulation or specific section or other provision thereof,
to any successor of such statute, regulation, section or other provision).  Any
reference in this Agreement to a "day" or number of "days" (without the explicit
qualification of "Business") shall be interpreted as a reference to a calendar
day or number of calendar days.  If any action or notice is to be taken or given
on or by a particular calendar day, and such calendar day is not a Business Day,
then such action or notice shall be deferred until, or may be taken or given on,
the next Business Day.  Unless otherwise expressly provided herein or unless the
context shall otherwise require, any provision of this Agreement using a term
(by way of example and without limitation, such as "members of the Magness
Group," "members of the Malone Group," "Affiliate" or Controlled Affiliate") the
definition of which is based on a specified characteristic, qualification,
feature or status shall, as of any time, refer only to such Persons who or other
things which have the specified characteristic, qualification, feature or status
as of that particular time.  When used with reference to any Right, the term
"exercise" shall mean to exercise the right to subscribe for, purchase or
otherwise acquire shares of capital stock represented by such Right, and
variants of such word (including "exercised" and "exercisable") shall have
correlative meanings.
 
     (b)  In the event of any stock split, stock dividend, recapitalization or
other change in any Company's capital structure affecting the outstanding shares
of any class or series of its capital stock, there shall be an appropriate
adjustment in the kind, number or percentage of shares of such class or series
specified in any provision of this Agreement under which (i) an action requires
the approval or consent of the holders of a specified or determinable number or
percentage of shares of such class or series or (ii) the effectiveness,
enforceability or parameters of a right granted to any 

                                       15
<PAGE>
 
Person, or an agreement, covenant or obligation of any Person, is stated to
depend upon ownership of a specified or determinable number or percentage of
shares of such class or series.

     (c)  In the event that any shares of capital stock or other securities of
any issuer of any class or series are or could be deemed to be Beneficially
Owned by more than one member of the Magness Group or more than one member of
the Malone Group, then for purposes of any provision of this Agreement under
which (i) an action requires the approval or consent of the members of either
Group that Beneficially Own a specified or determinable number or percentage of
such shares of capital stock or other securities or (ii) the effectiveness,
enforceability or parameters of any right or obligation of either Group or any
or all members thereof is stated to depend upon or be based upon Beneficial
Ownership of a specified or determinable number, amount or percentage of shares
or other securities of such class or series, no such share or other security
shall be deemed to be Beneficially Owned by more than one member of such Group
or shall otherwise be counted or taken into account more than once.

     (d)  The headings of the articles and sections contained in this Agreement
are solely for the purpose of reference, are not part of the agreement of the
parties and shall not affect the meaning or interpretation of this Agreement.

     (e)  Each party and its own legal counsel have participated in the drafting
of this Agreement, and this Agreement will be construed simply and according to
its fair meaning and not strictly for or against any party.

     Section 6.2.   Determinations and Group Actions Generally.
                    ------------------------------------------ 

     (a)  Unless otherwise expressly provided herein, all decisions and
determinations (including any decision as to whether to give any consent or
approval) required or permitted to be made hereunder by any one or more Persons
(including any party or parties to this Agreement) shall be made by such Person
or Persons in its or their sole discretion.  Any notice, consent, approval or
other decision by or on behalf of either Group or required or permitted by this
Agreement shall be effective if expressed in a writing which is either (i)
executed by a member or members of such Group that Beneficially Own issued and
outstanding TCI High Vote Shares equal to at least a majority of the aggregate
number of all issued and outstanding TCI High Vote Shares Beneficially Owned by
all members of such Group collectively, or (ii) in the case of the Magness
Group, executed by the Magness Group Representative or (iii) in the case of the
Malone Group, executed by JCM, and in any such case the parties to this
Agreement may assume that such member or members, the Magness Group
Representative or JCM, as the case may be, has the power and authority to do so
and may rely conclusively on such writing as expressing the action of the
Magness Group or the Malone Group, as the case may be.  JCM shall not be liable,
in damages or otherwise, to any party to this Agreement, any Company, any of the
Affiliates, stockholders, directors, officers, employees or agents of any such
Person or to any other Person for or by reason of any action or

                                       16
<PAGE>
 
omission in his capacity as the representative of the Malone Group. No Magness
Group Representative shall be liable, in damages or otherwise, to any party to
this Agreement, any Company, any of the Affiliates, stockholders, directors,
officers, employees or agents of any such Person or to any other Person for or
by reason of any action or omission in his capacity as the Magness Group
Representative unless such act or failure to act was not within the scope of the
authority or discretion conferred on the Magness Group Representative by this
Agreement.

     (b)  The Magness Group may designate any of its members as the Magness
Group Representative by written notice of such designation (and containing such
representatives address for notices and other communications) delivered to TCI
and JCM.  In the event of the death, incapacity or removal of the Person serving
as the Magness Group Representative, the Magness Group shall promptly designate
a successor.  Pending such designation, each party to this Agreement shall be
entitled to treat as the Magness Group Representative the member of the Magness
Group who holds of record the greatest number of TCI High Vote Shares.

     (c)  Unless otherwise expressly provided in this Agreement, this Agreement
is not intended to create any "group" obligations or liabilities; the
obligations and liabilities of the members of each Group shall be several and
not joint; and no member of either Group or nor any other party hereto or Person
referred to herein shall have any obligation or liability for the obligations or
liabilities of any other member of such Group, any other party or any other
Person.  Without limiting the generality of the foregoing, unless otherwise
expressly provided in this Agreement, if any member of either Group becomes
obligated to purchase, sell or vote any shares of capital stock or other
securities pursuant to this Agreement, such obligation shall be solely the
individual obligation of such member.  Each party shall be separately and
independently entitled to rely on the representations and warranties of each
other party made to in this Agreement and to the benefit of all agreements,
covenants, obligations and commitments of each other party made with or to such
party or the Group of which such party is a member.

     (d)  No member of either Group who acquires any shares of capital stock or
other securities from any member of the other Group shall be or become a member
of such other Group unless otherwise agreed in writing by such acquiring member,
JCM and the Magness Representative.

     Section 6.3.   Rights of Ownership; Obligations Subject to Applicable Laws.
                    -----------------------------------------------------------
Nothing contained in this Agreement shall create any obligation or restriction
on the part of any member of either Group in the exercise and enjoyment of full
rights of ownership of any shares of capital stock or other securities
Beneficially Owned by such Person, except as expressly provided in this
Agreement.  The obligations of JCM and any other member of the Malone Group
pursuant to Article II, III or IV shall in all cases be subject to and qualified
by (i) the mandatory requirements of applicable laws, rules and regulations from
time to time in effect, including the receipt of all consents and approvals of
Governmental Authorities required and the expiration of all waiting periods
applicable under any such law, rule or regulation without the commencement or
threat of commencement of any action or proceeding seeking to enjoin or impose
damages or penalties by reason of the consummation of any transaction
contemplated by any such Article or to impose any restrictions, limitations,
requirements or conditions which are or might be burdensome or adverse to any
member of the Malone Group or any Company, and (ii) the absence of any material
breach or violation of this Agreement or either Call Agreement by any member of
the Magness Group.

     Section 6.4.     Legends; Stop Transfers.
                      ----------------------- 

     (a)  Each certificate or other instrument representing any shares of
capital stock, Rights or other securities that are Beneficially Owned by any
member of either Group that are subject to any of the provisions of this
Agreement or either Call Agreement shall bear a legend substantially in the
following form, in addition to any other legend required under applicable law or
by contract:

     "THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE TERMS
     AND CONDITIONS OF A CERTAIN STOCKHOLDERS' AGREEMENT AND/OR CALL AGREEMENT,
     EACH DATED AS OF FEBRUARY __, 1998 BY AND AMONG TELE-COMMUNICATIONS, INC.,
     A DELAWARE CORPORATION, AND CERTAIN OF ITS STOCKHOLDERS. A COPY OF EACH
     SUCH AGREEMENT IS ON FILE AT THE PRINCIPAL OFFICE OF THE ISSUER OF THE
     SECURITIES REPRESENTED BY THIS CERTIFICATE.  THE SALE, PLEDGE, TRANSFER OR
     OTHER DISPOSITION OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE OR ANY
     INTEREST THEREIN IS RESTRICTED BY SUCH AGREEMENT(S) AND ANY SUCH SALE,
     PLEDGE, TRANSFER OR OTHER DISPOSITION MAY BE MADE ONLY UPON COMPLIANCE
     THEREWITH.  SUCH AGREEMENT(S) ALSO CONTAIN(S) PROVISIONS RELATING TO THE
     EXERCISE OF CERTAIN VOTING AND CONSENT RIGHTS, IF ANY, OF THE HOLDER OF THE
     SECURITIES REPRESENTED BY THIS CERTIFICATE AND MAY GRANT THE ISSUER OR
     OTHERS THE RIGHT TO PURCHASE SUCH SHARES UNDER CERTAIN CIRCUMSTANCES."

     (b)  Unless the Person(s) to whom such Disposition is made (the
"transferor(s)") is already a party to and bound by this Agreement or an
applicable Call Agreement or is required by the terms

hereof or thereof to become such a party or this Agreement, or an applicable
Call Agreement requires that the shares, Rights or other securities Disposed of
continue to be subject to this Agreement or an applicable Call Agreement, if any
shares of capital stock, Rights or other securities represented by a certificate
or other instrument that bears the legend set forth in subsection 6.4(a) are
Disposed of in a transaction that is permitted by the provisions of this
Agreement and the provisions of an applicable Call Agreement, the transferor(s)
shall be entitled to receive from the issuer a new certificate or instrument, of
like tenor but without the legend set forth in subsection 6.4(a), representing
the shares, Rights or other securities so Disposed of that are not required to
continue to be subject to either this Agreement or such applicable Call
Agreement. In the case of any such Disposition of only part of the shares,
Rights or other securities evidenced by a certificate bearing such legend, the
certificate representing the shares, Rights or other securities that are not
Disposed of shall continue to bear such legend.

     (c)  Each Company agrees that it shall not, and shall direct each registrar
and transfer agent of the Company not to, register any Disposition of any
securities of such Company by any member of either Group that is not made in
compliance with the applicable provisions of this Agreement.

     Section 6.5.  Binding Effect; Assignability.  This Agreement and all of the
                   -----------------------------                                
provisions hereof (including the exhibits and schedules hereto) shall be binding
upon and inure to the benefit of the parties hereto and their respective
successors, assigns, heirs, executors, administrators and personal
representatives, and except as otherwise expressly provided herein, nothing in
this Agreement, express or implied, is intended or shall be construed to confer
upon or give any Person other than the parties any right, benefit, remedy or
claim under or by reason of this Agreement or any term, covenant or condition
hereof.  Except as otherwise specifically permitted or required pursuant to this
Agreement, neither this Agreement nor any of the rights, interests or
obligations hereunder shall be assigned by any party without the prior written
consent of TCI, JCM and the Magness Group Representative.  The disability,
incapacity, bankruptcy, insolvency, dissolution, liquidation or death of any
member of the Malone Group or any member of the Magness Group shall not result
in the termination or otherwise affect the rights or obligations of any such
Person under this Agreement, it being agreed that such member's heirs,
successors, assigns and legal representatives shall, in their capacities as
such, succeed to all of such member's rights and obligations hereunder.  Without
limiting the generality of the foregoing, in the event of the disability,
incapacity, or death of JCM, his executors or other legal representatives, in
their capacities as such, and his heirs or distributees shall succeed to all of
JCM's rights and obligations hereunder; provided, however, that, unless JCM's

executors, administrators or heirs otherwise agree with the Magness Group
Representative, in the event of JCM's death, (x) all High Vote Shares of any
Company of any class or series subject to the voting rights of JCM under Section
2.2 shall be voted (or any other action required or requested of the holders of
shares of that class or series shall be taken) in the manner directed or
recommended by the Board of Directors of that Company and (y) unless TCI shall
elect, on or before the latest date permitted by the Magness Call Agreement, to
exercise its Call Right under Section 2.2 of the Magness Call Agreement, or if
having made that election the closing under such Call

Agreement shall not occur when required (otherwise as a result of a default by
any member of the Magness Group), all further rights and obligations of the
parties under Sections 2.1 and 2.2 (as modified by clause (x) of this provision)
shall terminate as of that latest date or the required closing date, as the case
may be.

     Section 6.6.  Amendments and Waivers.  The provisions of this Agreement,
                   ----------------------                                    
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers of or consents to departures from the provisions
hereof may not be given unless approved in writing by TCI, JCM and the Magness
Group Representative.  For the sake of certainty, the parties specifically agree
that (i) any supplemental agreement or instrument by which any Person who is not
already a party to this Agreement agrees, as required or permitted by this
Agreement, to become a party to and be bound by this Agreement and (ii) any
amendment or supplement to this Agreement to reflect transfers or other
transactions in accordance with this Agreement, and which does not, in either
case, purport to amend, modify, waive or supplement in any material respect any
of the substantive provisions hereof, shall be effective if executed by such
Person, TCI, JCM and the Magness Group Representative.

     Section 6.7  Governing Law.  This Agreement and the validity,
                  -------------                                   
interpretation and performance of the terms and provisions hereof shall be
governed by, and construed in accordance with, the laws of the State of
Delaware, without regard to the provisions thereof relating to choice or
conflict of laws.

                  ------------------                                   
Agreement, including any investigation by or on behalf of any party, shall be
deemed to constitute a waiver by the party taking such action of compliance with
any representations, warranties, covenants or agreements contained herein or
made pursuant hereto.  The waiver by any party hereto of a breach of any
provision of this Agreement shall not operate or be construed as a waiver of any
preceding or succeeding breach and no failure by any party to exercise any right
or privilege hereunder shall be deemed a waiver of such party's rights or
privileges hereunder or shall be deemed a waiver of such party's rights to
exercise the same at any subsequent time or times hereunder.

     Section 6.10  Entire Agreement.  This Agreement (together with the Exhibits
                   ----------------                                             
and Schedules hereto, if any) constitutes the entire agreement of the parties
with respect to the specific subject matter hereof, and merges and supersedes
all prior agreements and undertakings, both written and oral, among the parties
with respect to such specific subject matter.  For the sake of certainty, the
parties specifically acknowledge that (i) this Agreement is not intended to
merge, supersede or alter the provisions of (A) either Call Agreement, (B) any
provision of the Settlement Agreement other than numbered paragraph 8 thereof,
or (C) any separate agreement, release or instrument granted, entered into or
delivered pursuant to the Settlement Agreement; and (ii) unless this Agreement
is terminated under subsection (b), (c), (d) or (e) of Section 6.20, this
Agreement and the Call Agreements will, as among the parties and effective as of
the Effective Date, merge and supersede the letter agreement, dated June 17,
1988, among Bob Magness, Malone and Kearns-Tribune Corp. relating to the shares
of TCI Common Stock owned by them.  The respective representations and
warranties of the parties shall survive the execution and delivery of this
Agreement.
 
     Section 6.11  Inspection.  Copies of this Agreement will be available for
                   ----------                                                 
inspection or copying by any stockholder of TCI or any other Company that shall
be a party to this Agreement through the secretary of TCI or such other Company.

     Section 6.12  Counterparts.  This Agreement may be executed in one or more
                   ------------                                                
counterparts, each of which shall be deemed to be an original and all of which
together shall be deemed to constitute one and the same agreement.

     Section 6.13.  Further Assurances.  Each party shall cooperate and take
                    ------------------                                      
such actions as may be reasonably requested by another party in order to carry
out the provisions and purposes of this Agreement and the transactions
contemplated hereby.
 
     Section 6.14.  Specific Performance; Injunctive Relief; Remedies Are
                    -----------------------------------------------------
Cumulative.  Without intending to limit the rights or remedies available to any
- ----------                                                                     
of the parties pursuant to this Agreement, a Call Agreement, at law or in equity
(all of which shall be cumulative), each of the parties 

                                       21
<PAGE>
 
acknowledges that a violation by such party of any provision of this Agreement
will cause the other parties irreparable injury for which an adequate remedy at
law is not available and, therefore, the parties agree that the provisions of
this Agreement shall be specifically enforceable, that each party shall be
entitled to an injunction, restraining order, decree of specific performance or
other form of equitable relief from any court of competent jurisdiction
restraining any other party from committing any breach or threatened breach of,
or otherwise specifically to enforce, any provision of this Agreement, and each
party hereby waives and agrees not to assert in any action or proceeding in
which any such form of relief is sought any defense that a remedy at law would
be adequate. The rights and remedies herein expressly provided are cumulative
and not exclusive of any other rights or remedies which any party would
otherwise have pursuant hereto, at law, in equity, by statute or otherwise.

     Section 6.15  Severability.  If any provision of this Agreement or the
                   ------------                                            
application thereof to any person or circumstance is held by a court of
competent jurisdiction to be invalid, void or unenforceable, the remaining
provisions hereof, or the application of such provision to persons or
circumstances other than those as to which it has been held invalid or
unenforceable, shall remain in full force and effect and shall in no way be
affected, impaired or invalidated thereby, provided, that if any provision
hereof or the application thereof shall be so held to be invalid, void or
unenforceable by a court of competent jurisdiction, then such court may
substitute therefor a suitable and equitable provision in order to carry out, so
far as may be valid and enforceable, the intent and purpose of the invalid, void
or unenforceable provision and, if such court shall fail to decline to do so,
the parties shall negotiate in good faith in an effort to agree upon such a
suitable and equitable provision.  To the extent that any provision shall be
judicially unenforceable in any one or more states, such provision shall not be
affected with respect to any other state, each provision with respect to each
state being construed as several and independent.
