     1. GRANT OF STOCK APPRECIATION RIGHTS; TERM; RELEASE. (a) The Company
hereby grants to Grantee stock appreciation rights ("SARS") with respect four
(4) Share Units on the terms and subject to the conditions set forth herein.
Subject to paragraph 2 and 3(b), the SARs shall be exercisable in whole at any
time and in part from time to time during the period commencing on the date
hereof and expiring at 5:00 p.m., Denver, Colorado time ("CLOSE OF BUSINESS"??on
the tenth anniversary of the Determination Date, or such earlier date as the
SARs may be terminated pursuant to paragraph 6 or paragraph 9(a) (the "TERM").

        (b) The grant of SARs hereunder shall be deemed to be in substitution
for and replacement of the stock appreciation rights with respect to the shares
of common stock of Internet Services which were previously granted by Internet
Services to Grantee, and the parties acknowledge and agree that such prior stock
appreciation rights grant is hereby terminated and shall cease to be of any
further force and effect. Grantee hereby irrevocably releases Internet Services
and TCI from any and all obligations under the Prior SAR Agreement.

     2. CONDITIONS OF EXERCISE; VESTING. (a) Except as otherwise provided in
paragraph 2(b) or in paragraph 9(a), (i) the SARs shall not be exercisable
immediately, (ii) two (2) SARs will vest and become exercisable on February 1,
2000 and (iii) all unexercised SARs will vest and become exercisable on February
1, 2001.

        (b) Notwithstanding the foregoing, all then unexercised SARs (the
"REMAINING SARS") shall become immediately exercisable if during the Term (i)
Grantee's employment with the Company Group shall terminate by reason of (x)
termination by the Company Group without Cause, (y) termination by Grantee for
Good Reason or (z) Disability, (ii) Grantee's employment shall terminate
pursuant to provisions of a written agreement, if any, between Grantee and the
applicable member(s) of the Company Group which expressly permits Grantee to
terminate such employment upon the occurrence of specified events (other than
the giving of notice and passage of time) or (iii) Grantee dies while employed
by the Company Group. A change of employment is not a termination of employment
within the meaning of this paragraph 2(b), provided that, after giving effect to
such change, Grantee is an employee of, or becomes or continues to be a
consultant to, any member of the Company Group.

     3. EXERCISE OF SARS. (a) SARs granted hereunder may be exercised by
delivery to the Company of a written notice (the "EXERCISE NOTICE") specifying
the whole number of SARs being exercised. The date upon which such notice is
validly delivered to the Company shall be deemed to be the date of exercise of
the SARs specified therein (the "EXERCISE DATE"). Upon the valid exercise of
SARs, Grantee shall be entitled to receive from the Company, with respect to
each SAR then being exercised, the excess of (x) the Per Share Unit Value as of
the Exercise Date over (y) the Strike Price (such excess, the "CASH VALUE").
Upon a valid exercise of a SAR and payment in full by the Company of the Cash
Value in respect thereof, such SAR shall be deemed canceled and will cease to be
outstanding.

        (b) The minimum number of SARs which may be exercised at any time will
be one (1).



                                       2
<PAGE>   3


        (c) If on the Exercise Date @Home is not a Public Company and the value
of the @Home Common Stock is not otherwise established pursuant to Schedule 1,
then, Grantee shall have the right to rescind an exercise of SARs prior to the
Close of Business on the fifteenth (15th) day following the Exercise Date in the
event that (i) Grantee has elected to determine the Per Share Unit Value through
negotiation with the Company, (ii) Grantee and the Company have not agreed upon
a Per Share Unit Value by such date and (iii) Grantee has not made a subsequent
election to require that the Per Share Unit Value be determined by appraisal
pursuant to paragraph 10(c) hereof. In addition, an exercise of SARs shall be
deemed rescinded under the circumstances set forth in paragraph 10(b) hereof. In
the event of any rescission of an exercise of SARs pursuant to this paragraph
3(c), Grantee shall not be permitted to again exercise SARs for a period of
thirty (30) days following the date of such rescission.

        (d) In the event the Grantee elects to rescind his exercise of SARs in
accordance herewith, such exercise shall be deemed rescinded ab initio and the
future exercisability and vesting of those SARs whose exercise has been
rescinded shall not be affected by such exercise and subsequent rescission,
except as provided in the last sentence of paragraph 3(c) above.

     4. WITHHOLDING FOR TAXES. It shall be a condition precedent to any exercise
of a SAR that Grantee make provision acceptable to the Company for the payment
or withholding of any and all federal, state and local taxes required to be
withheld by the Company to satisfy the tax liability associated with such
exercise, as determined by the Company Board.

     5. DELIVERY BY THE COMPANY. (a) Subject to the withholding referred to in
paragraph 4, the Company shall deliver or cause to be delivered to Grantee the
Cash Value of the SARs then being exercised, with such amount being paid, at the
Company's election, in (i) cash, (ii)(x) provided that the Company is then a
Public Company and that the Company's common stock is then listed or traded on
NASDAQ or a national securities exchange and is actively traded, shares of the
Company's common stock (and if more than one series of such common stock is
created with different voting rights, the series with the lower voting rights),
or (y) shares of AT&T Class A Liberty Media Group Common Stock, $1.00 par value
per share, or any successor class or series of AT&T's common stock which is
intended to reflect the business and assets of the Company and which is listed
or traded on NASDAQ or a national securities exchange and is actively traded
("COMPANY COMMON STOCK"), (iii) shares of any class or series of capital stock
of any other Person, provided that shares of the same class and series of
securities being so delivered are then listed or traded on NASDAQ or a national
securities exchange and are actively traded ("OTHER STOCK"), or (iv) any
combination of cash, Company Common Stock and Other Stock, as the Company may
elect. It shall be a condition to the Company's right to deliver shares of
Company Common Stock or Other Stock in satisfaction of its obligations hereunder
that (i) (x) the issuance of such shares to Grantee shall have been registered
under the Securities Act of 1933, as amended (the "SECURITIES ACT"), on Form S-8
(or other appropriate form) and (y) such shares may be immediately sold in the
market by Grantee (either pursuant to Rule 144 or a resale prospectus ) or (ii)
such shares may be sold to Grantee without registration under the Securities Act
and Grantee's immediate resale of such shares is not prohibited or otherwise
restricted by the registration requirements of the Securities Act. If the
Company elects 




                                       3
<PAGE>   4

to pay all or any portion of the Cash Value in shares of Company Common Stock or
Other Stock, said shares shall be valued for such purpose at the most recent
Closing Price thereof as of the date of delivery of such shares to Grantee. The
payment of the Cash Value (in cash or by delivery of Company Common Stock or
Other Stock) shall be made (i) if each of the Subject Companies is a Public
Company, on the 10th day following the Exercise Date and (ii) if each of the
Subject Companies is not a Public Company, on the 10th day following either (x)
the date Grantee and the Company mutually agree as to the Agreed Per Share Unit
Value or (y) the receipt by Grantee and the Company of notice pursuant to
paragraph 10(c) of the final determination of the Appraised Per Share Unit Value
(or on such other date as the parties may agree).

     6. EARLY TERMINATION OF SARS. Unless otherwise determined by the Company
Board in its sole discretion, the SARs shall terminate prior to the expiration
of the ten-year period provided for in paragraph 1, as follows:

        (a) If Grantee's employment with the Company Group terminates other than
     (i) by Grantee with Good Reason, (ii) by reason of Grantee's death or
     Disability, (iii) with the written consent of the applicable member(s) of
     the Company Group, (iv) without such consent if such termination is
     pursuant to provisions of a written employment agreement, if any, between
     Grantee and the applicable member(s) of the Company Group which expressly
     permits Grantee to terminate such employment upon the occurrence of
     specified events (other than the giving of notice and passage of time), or
     (v) by the Company Group with or without Cause, then the SARs shall
     terminate at the Close of Business on the first business day following the
     expiration of the 90-day period beginning on the date of termination of
     Grantee's employment;

        (b) If Grantee dies (i) while employed by the Company Group or (ii)
     prior to the expiration of a relevant period of time following termination
     of employment during which the SARs remain exercisable as provided in this
     paragraph 6, the SARs shall terminate at the Close of Business on the first
     business day following the expiration of the one-year period beginning on
     the date of death;

        (c) If Grantee's employment with the Company Group terminates by reason
     of Disability, then the SARs shall terminate at the Close of Business on
     the first business day following the expiration of the one-year period
     beginning on the date of termination of Grantee's employment;

        (d) If Grantee's employment with the Company Group is terminated by the
     Company Group for Cause, then the SARs shall terminate immediately upon
     such termination of Grantee's employment; and

        (e) If Grantee terminates his employment with the Company Group (i) with
     Good Reason, (ii) with the written consent of the applicable member(s) of
     the Company Group or (iii) pursuant to provisions of a written employment
     agreement, if any, between Grantee and the applicable member(s) of the
     Company Group which expressly permits Grantee to 



                                       4
<PAGE>   5

     terminate such employment upon the occurrence of specified events (other
     than the giving of notice and passage of time), or if the Company Group
     terminates Grantee's employment with the Company Group without Cause, then
     the Term shall not terminate prior to the end of the ten-year period
     provided for in paragraph 1, except as otherwise provided for in paragraph
     6(b) or 9(a).

     In any event in which the SARs remain exercisable for a period of time
following the date of termination of Grantee's employment as provided above,
such SARs may be exercised during such period of time only to the extent they
were exercisable as provided in paragraph 2 or paragraph 9(a) on such date of
termination of Grantee's employment (after giving effect to any acceleration
provided for in paragraph 2(b)). A change of employment is not a termination of
employment within the meaning of this paragraph 6, provided that, after giving
effect to such change, Grantee is an employee of, or becomes or continues to be
a consultant to, any member of the Company Group. Anything contained herein to
the contrary notwithstanding, the SARs shall in any event terminate upon the
expiration of the ten-year period provided for in paragraph 1, if not
theretofore terminated.

     7. NONTRANSFERABILITY OF SARS. During Grantee's lifetime, the SARs are not
and shall not be transferable (voluntarily or involuntarily) other than pursuant
to a Domestic Relations Order and, except as otherwise required pursuant to a
Domestic Relations Order, the SARs shall be exercisable only by Grantee or
Grantee's court appointed legal representative. Grantee may designate a
beneficiary or beneficiaries to whom the SARs shall pass upon Grantee's death
and may change such designation from time to time by filing a written
designation of beneficiary or beneficiaries with the Company on the form annexed
hereto as Exhibit A or such other form as may be prescribed by the Company
Board, provided that no such designation shall be effective unless so filed
prior to the death of Grantee. If no such designation is made or if the
designated beneficiary does not survive Grantee's death, the SARs shall pass by
will or the laws of descent and distribution. Following Grantee's death, the
SARs, if otherwise exercisable, may be exercised by the person to whom the SARs
pass according to the foregoing, and such person shall be deemed to be Grantee
for purposes of any applicable provisions of this Agreement.

     8. NO SHAREHOLDER RIGHTS; NO GUARANTEE OF EMPLOYMENT; UNSECURED OBLIGATION.
(a) Grantee shall not be deemed for any purpose to be, or to have any of the
rights of, a stockholder of the Company by virtue of the SARs. The existence of
this Agreement and Grantee's rights hereunder shall not affect in any way the
right or power of the Company or its stockholders to accomplish any corporate
act.

        (b) Nothing contained in this Agreement, and no action by the Company or
the Company Board with respect hereto, shall confer or be construed to confer on
Grantee any right to continue in the employ of the Company Group or any member
thereof or interfere in any way with the right of the Company or any employing
member of the Company Group to terminate Grantee's employment at any time, with
or without Cause, except as otherwise expressly provided in any written
agreement between the applicable member(s) of the Company Group and Grantee.



                                       5
<PAGE>   6

        (c) The amount of cash payable at any time by the Company upon the valid
exercise of SARs granted hereunder shall not in any way be reserved or held in
trust by the Company. Grantee shall not have any rights against the Company in
respect of payments of such amount of cash other than as the rights of an
unsecured general creditor of the Company. The amount of cash payable upon the
valid exercise of SARs hereunder shall not be subject in any manner to
anticipation, alienation, sale, transfer, assignment, pledge, encumbrance or
charge, and shall not in any manner be liable or subject to the debts,
contracts, liabilities, engagements or torts of Grantee or of any designated
beneficiary or personal representative.

     9. ACCELERATION; AUTOMATIC EXERCISE. (a) The Company Board may at any time
in its sole discretion determine that the SARs shall become exercisable in full,
without regard to paragraph 2, whether immediately, upon the occurrence of
specified events, or otherwise. Without limiting the generality of the
foregoing, in the event of any Board Change, Control Purchase or Approved
Transaction that occurs with respect to the Company following the effective time
of the Merger and prior to such time as the Company is no longer a Subsidiary of
TCI, the SARs shall become exercisable in full, without regard to paragraph 2,
effective upon the Board Change or Control Purchase or immediately prior to
consummation of the Approved Transaction, as applicable (or at such earlier time
as the Company Board in its sole discretion may determine); provided, however,
that to the extent not theretofore exercised the SARs shall terminate upon the
first to occur of the consummation of the Approved Transaction or the expiration
or early termination of the Term. Notwithstanding the foregoing, the Company
Board may, in its discretion, determine that the SARs will not become
exercisable on an accelerated basis in connection with an Approved Transaction
and/or will not terminate if not exercised prior to consummation of the Approved
Transaction, if the Company Board or the surviving or acquiring corporation, as
the case may be, shall have taken or made effective provision for the taking of
such action as in the opinion of the Company Board is equitable and appropriate
to substitute new stock appreciation rights for the SARs evidenced by this
Agreement (provided that no change in the Subject Companies or Subject
Securities, as in effect immediately prior to such event, is made in connection
with such substitution), or to assume this Agreement and the SARs evidenced
hereby and in order to make such new or assumed stock appreciation rights, as
nearly as may be practicable, equivalent to the SARs evidenced by this Agreement
as then in effect (but before giving effect to any acceleration of the
exercisability hereof unless otherwise determined by the Company Board).

        (b) All actions taken by the Company Board with respect to the SARs
pursuant to this paragraph 9 shall be consistent with any actions taken by the
Company Board with respect to the Other SARs.

        (c) Immediately prior to the termination of the SARs as provided in
paragraph 6 above (other than pursuant to paragraph 6(d)), this paragraph 9, or
the expiration of the Term, all Remaining SARs shall be deemed to have been
exercised by Grantee and Grantee shall be deemed to have taken all actions
required by paragraph 3(a) for a valid exercise of SARs.

     10. RESTRICTIONS IMPOSED BY LAW; AGREED PER SHARE UNIT VALUE; APPRAISAL
PROCEDURES. (a) Grantee acknowledges that neither the SARs nor the interests
evidenced thereby 




                                       6
<PAGE>   7

have been registered under the Securities Act and that neither the SARs nor such
interests may be transferred in the absence of such registration or the
availability of an exemption therefrom under the Securities Act or the rules and
regulations of the Securities and Exchange Commission promulgated thereunder.
Neither the Company nor any other person shall have any obligation to register
the SARs or the interests represented thereby, or any transfer of the SARs or
the interests represented thereby, under the Securities Act, the Exchange Act or
any other state or federal securities law.

        (b) Except as otherwise provided in Schedule 1 hereto, in the event that
the Subject Securities of one or more of the Subject Companies are not Publicly
Traded as of the Exercise Date (each such Subject Company whose Subject
Securities are not Publicly Traded, a "PRIVATE ISSUER"), Grantee shall have the
right to elect that portion of the Per Share Unit Value attributable to the
securities of a Private Issuer (the "PRIVATE SHARES") be determined by appraisal
as provided herein or to seek to negotiate a mutually acceptable Private Share
Value in respect thereof with the Company; provided, that in the event Grantee
and the Company are unable to agree upon all Private Share Values prior to the
Close of Business on the fifteenth (15th) day following the Exercise Date, then
Grantee shall have the further right (subject to the last sentence of paragraph
10(c) below), exercisable by written notice to the Company, to require that any
Private Share Value as to which Grantee and the Company have not agreed be
determined by appraisal as provided herein. In the event that @Home is a Private
Issuer and Grantee and the Company have not agreed upon the Private Share Value
of the @Home securities included in a Share Unit as of the Close of Business on
such fifteenth (15th) day and the Grantee has not delivered notice requiring
appraisal, the Grantee shall be deemed to have rescinded the exercise of SARs
pursuant to paragraph 3 hereof. In the event that either or both of Sportsline
or iVillage is a Private Issuer, Grantee shall have no right to rescind the
exercise of the SARs, and instead shall be deemed to have delivered at the Close
of Business on such fifteenth (15th) day notice requiring appraisal of such
Private Shares. In the event that Grantee elects to seek to negotiate the
Private Share Value with the Company, each party agrees to negotiate in good
faith and use its commercially reasonable efforts to agree upon the Agreed
Private Share Value. The parties acknowledge and agree that in connection with
such negotiations the parties shall give due consideration to the determination
of the Fair Market Value of each Private Issuer (as set forth in the definition
thereof) and the number of shares of Private Issuer Common Stock outstanding
(based upon the principles set forth in paragraph 10(c) hereof).

        (c) In the event Grantee elects to require that any Private Share Value
be determined by appraisal, Grantee shall specify in the Exercise Notice or the
subsequent written notice to the Company electing appraisal (or in a written
notice to the Company following a deemed request for appraisal the identity of
the Appraiser selected by Grantee to make the determination of the Fair Market
Value of 




                                       7
<PAGE>   8

each Private Issuer (the "FIRST APPRAISER"). Within three (3) business days
following receipt of such notice, the Company shall notify Grantee in writing as
to the identity of the Appraiser selected by the Company (the "SECOND
APPRAISER"). The Appraisers selected pursuant to this paragraph 10(c) shall make
separate determinations of the Fair Market Value of each Private Issuer in
accordance with the provisions of this paragraph 10(c), and Grantee and the
Company shall each be entitled to a single Appraiser in respect of any exercise
of SARs hereunder. The First Appraiser and the Second Appraiser shall each
submit its determination of the Fair Market Value of each Private Issuer to
Grantee and the Company within thirty (30) days of the date of selection of the
Second Appraiser. If the respective determinations of the Fair Market Value of a
Private Issuer by such Appraisers vary by less than 10% of the higher
determination, then the Fair Market Value of such Private Issuer shall be the
average of the two determinations. If such determinations vary by 10% or more of
the higher determination, the two Appraisers shall promptly designate a third
Appraiser (the "THIRD APPRAISER"). Neither Grantee nor the Company shall
provide, and the First Appraiser and Second Appraiser shall be instructed not to
provide, any information to the Third Appraiser as to the determination of the
First Appraiser and Second Appraiser or otherwise influence such Third
Appraiser's determination. The Third Appraiser shall submit its determination of
the Fair Market Value of such Private Issuer to Grantee and the Company within
fifteen (15) days of the date of its selection. The Fair Market Value of such
Private Issuer shall be equal to the average of the two closest of the three
determinations, provided, 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, the Fair Market Value of such
Private Issuer shall be equal to the middle determination. Following the
determination of the Fair Market Value of each such Private Issuer, the
Appraisers whose determinations were used in the calculation of the Fair Market
Value of such Private Issuer shall determine the number of shares of Private
Issuer Common Stock outstanding together with any further appropriate
adjustments to the Fair Market Value of such Private Issuer resulting from such
determination. The number of shares of Private Issuer Common Stock outstanding
with respect to such Private Issuer shall mean a number, as determined by such
Appraisers as of the applicable date, equal to the sum of the number of shares
of Private Issuer Common Stock outstanding with respect to such Private Issuer
and the number of shares of Private Issuer Common Stock issuable by such Private
Issuer upon the conversion, exercise or exchange of those Convertible Securities
the holders of which would derive an economic benefit from the conversion,
exercise of exchange of such Convertible Securities which exceeds the economic
benefits of not converting, exercising or exchanging such Convertible
Securities; provided, however, that shares of @Home Common Stock issuable upon
the exercise of warrants to purchase @Home Common Stock issued by @Home to cable
television operators, which warrants become exercisable only to the extent that
such operator has upgraded its cable system or is distributing the @Home high
speed internet access service over its cable plant and equipment, such warrants
shall be deemed exercised only to the extent that such warrants are exercisable
in accordance with their terms as of the applicable Exercise Date. The
Appraisers shall then calculate the value per share of Private Issuer Common
Stock (the "APPRAISED PRIVATE SHARE VALUE") with respect to each Private Issuer
for which appraisal was required, which shall be the quotient obtained by
dividing the Fair Market Value of such Private Issuer by the number of shares of
Private Issuer Common Stock of such Private Issuer outstanding or deemed
outstanding; provided, that if such Appraisers do not agree on the number of
shares of Private Issuer Common Stock outstanding, each Appraiser whose
determination of the Fair Market Value of such Private Issuer is being used in
the calculation of such Appraised Private Share Value shall determine the
Appraised Private Share Value based upon its determination of the Fair Market
Value of such Private Issuer and the number of shares of Private Issuer Common
Stock of such Private Issuer outstanding, and the Appraised Private Share Value
shall be the average of the quotients so obtained on the basis of the respective
determinations of such firms. The Appraisers shall jointly notify the Company
and Grantee in writing of their final determination of the Appraised Private
Share Value as to each Private Issuer within five (5) days after the
determination of the Fair 




                                       8
<PAGE>   9

Market Value of the last of the Private Issuers with respect to which appraisal
is required. Grantee and the Company shall each pay the fees and expenses of his
or its own Appraiser and one-half of the fees and expenses of the Third
Appraiser, if any. Grantee acknowledges and agrees that he shall not be entitled
to require an appraisal pursuant to this Agreement more than once in any 12
month period. In connection with any appraisal pursuant to this paragraph 10,
the Company agrees that it shall use its commercially reasonable efforts to
obtain and (subject to the recipient agreeing to customary confidentiality
restrictions) make available to Grantee and any Appraiser, such financial and
business information concerning such Private Issuer as is reasonably necessary
to assist Grantee or such Appraisers in determining the Fair Market Value of
such Private Issuer.

     11. NOTICE. Unless the Company notifies Grantee in writing of a change of
address, any notice or other communication to the Company with respect to this
Agreement shall be in writing and shall be delivered personally or sent by first

         dividend or distribution, and the Subject Securities included in such
         Share Unit shall, upon expiration or termination of such rights,
         warrants or other securities, be re-adjusted to reflect such subsequent
         expiration or termination of such rights, warrants or other securities.

         transaction affecting any Subject Company, the applicable Subject
         Company and the Subject Securities included in each outstanding Share
         Unit will be adjusted following such occurrence by substituting for the
         affected Subject Company the successor by merger (or purchaser of
         assets) to such Subject Company, and thereafter such Share Unit will
         include therein as the Subject Securities of such successor Subject
         Company, the securities, cash or other property which a holder of such
         number of shares of Subject Securities immediately prior to the
         effectiveness of such merger or other transaction would have received
         as a result of such merger or other transaction. In the event that
         @Home ceases to be a Public Company as a result of any such merger or
         other business combination in which the holders of @Home Common Stock
         receive securities which are not Publicly Traded, the @Home Common
         Stock included in the Share Units shall be deemed to have been sold for
         an amount in cash equal to the Closing Price of the @Home Common Stock
         immediately prior to the effectiveness of such merger or other
         transaction, multiplied by the number of shares of @Home Common Stock
         included in such Share Unit, and the securities so received in respect
         thereof shall not become Subject Securities; to the extent that a
         holder of @Home Common Stock receives cash, Publicly Traded securities
         and/or securities which are not Publicly Traded, each share of @Home
         Common Stock will be deemed to have been sold for cash at such Closing
         Price, and the consideration received appropriately allocated among
         such components, with the securities which are not publicly traded
         being deemed sold for the cash component attributable thereto, and such
         securities shall not become Subject Securities.

                  In the event that Liberty Media Corporation ("Liberty") sells
         (other than in a merger or other transaction affecting all stockholders
         of such Subject Company) (a "Liberty Sale") all or a portion of (i) the
         2,861 shares of iVillage Common Stock held by it on the date hereof (as
         adjusted for the anticipated stock split) or (ii) the 2,133 shares of
         Sportsline Common Stock held by it on the date hereof (in each case, as
         such amount may be adjusted for stock splits, stock dividends and the
         like occurring after the date hereof (other than the iVillage Common
         Stock stock split referred to above), then if the proceeds of such sale
         consist of: (x) cash, then such cash shall be included in the Share
         Unit in respect of the Subject Securities sold; (y) securities which
         are Publicly Traded, such securities shall become Subject Securities in
         substitution for the Subject Securities so disposed of; and (z)
         securities which are not Publicly Traded, then the Subject Securities
         so disposed of shall be valued at the Closing Price thereof on the date
         immediately prior to such Liberty Sale, and such Subject Securities
         shall be deemed to have been sold for an amount of cash equal to the
         number of shares sold multiplied by such Closing Price, and the
         securities received in such Liberty Sale shall not become Subject
         Securities.

                  Any sale of @Home Common Stock by TCI, AT&T or their
         respective affiliates (other than Liberty), after the date hereof shall

         Liberty, as a dividend, interest payment or other distribution on such
         Subject Security, or otherwise), shall be and become a part of the
