obligated to purchase, and the Selling Partner shall be obligated to sell, the

copy to the Company.

                                    (c)      If AOLTW does not elect to
purchase all of the Offered Interest, then the Company shall be obligated to
purchase, and the Selling Partner shall be obligated to sell, the remaining
portion of the Offered Interest for a purchase price (the "Company Purchase
Price") equal to (x) the percentage of the Offered Interest not purchased by
AOLTW multiplied by (y) the Offered Interest FMV.

                                    (d)      The "Offered Interest FMV" shall
be determined as follows:

                                             (i)      Upon delivery of an
Appraisal Notice, the Selling Partner shall, by written notice to the Company,
designate an Investment Banking Firm to prepare a valuation of the Offered
Interest. Within five (5) days of delivery of the Appraisal Notice, the Company
shall, by written notice to the Selling Partner, designate a second Investment
Banking Firm to prepare a valuation of the Offered Interest; provided, that if
the Company fails to designate an Investment Banking Firm within such 5-day
period, the Investment Banking Firm selected by the Selling Partner shall
determine the Offered Interest FMV, without regard to the remainder of this
Section 3(d), in accordance with the guidelines set forth on Exhibit A.

                                             (ii)     Within ten (10) days
following the designation by the Company of the second Investment Banking Firm
pursuant to Section 3(d)(i), if such second Investment Banking Firm has been so
designated, the two Investment Banking Firms shall select a third Investment
Banking Firm and the Selling Partner and the Company shall engage such third
Investment Banking Firm on reasonable and customary terms. If the two
Investment Banking Firms are unable to agree on the identity of a third
Investment Banking Firm within such 10-day period, or the Selling Partner and
the Company are unable to agree as to the terms of engagement for such firm
within such period, then either the Selling Partner or the Company may refer
the matter to the American Arbitration Association (the "AAA") which shall
select such third Investment Banking Firm, and establish the terms of
engagement of such firm, within fifteen (15) days following such request;
provided that all parties shall be given notice of such referral and afforded
the opportunity to participate in any presentations to be made to the AAA. The
firm selected by the AAA shall not derive a material portion of its revenues
from either the Selling Partner, the Company or any of their respective
Affiliates, shall have experience in valuing companies engaged in the same
business then engaged in by TWE and shall be engaged on reasonable and
customary terms.

                                             (iii)    No later than thirty (30)
days following the delivery of the Appraisal Notice, the Investment Banking
Firm selected by the Selling Partner and the Investment Banking Firm selected
by the Company shall simultaneously disclose to each other their respective
determinations of the fair market value of the Offered Interest, each of which
shall be prepared in accordance with the guidelines set forth in Exhibit A;
provided, that if either Investment Banking Firm is not prepared to disclose
its valuation on such day, the valuation of the Investment Banking Firm that is
so

                                                                              7


prepared shall be the Offered Interest FMV. If the amount of the higher of the
values determined by the two Investment Banking Firms is no more than 110% of
the lower value, such values will be averaged and such average shall be the
Offered Interest FMV. If the amount of the higher of the values determined by
the two Investment Banking Firms is more than 110% of the lower value, then on
a day no later than forty (40) days after the delivery of the Appraisal Notice,
each of the two Investment Banking Firms will make a presentation to the third
Investment Banking Firm, regarding the methodology and conclusions used by it
in arriving at its valuation. Each party and such party's Investment Banking
Firm shall be entitled to attend the presentation of the other party's
Investment Banking Firm. Within five (5) days following the presentations, the
third Investment Banking Firm shall determine which valuation more accurately
reflects the value of the Offered Interest, and such valuation shall be the
Offered Interest FMV and shall be final and binding upon the parties.

                                             (iv)     Each party will pay the
fees and expenses of the Investment Banking Firm it selects and 50% of the fees
and expenses of the third Investment Banking Firm. If the parties are unable to
agree on the fee payable to the third Investment Banking Firm, the fees shall
be set by the AAA and the parties shall each be liable for 50% of such fees.

                                    (e)      The Company will supply, subject
to the recipients entering into customary confidentiality agreements, the
following information regarding TWE and the Company to the Investment Banking
Firms and to the Selling Partner within fifteen (15) days of delivery of the
Appraisal Notice (except that information to be provided pursuant to a request
under "(4)" below shall be provided as soon as reasonably practicable after the
date of such request): (1) 3 years of historical financial statements, (2)
current year interim quarterly financial statements, (3) certain operating
statistics (e.g. subscribers, homes passed, rebuild status) and (4) other due
diligence items that any appraiser may reasonably request (but, with respect to
(4), only the extent such information exists or is readily available within the
relevant time period). In addition to such information, if, upon the delivery
of an Appraisal Notice, the Selling Partner elects in writing to have the
Company prepare projections for the Company and TWE for the then-current fiscal
year and one (1) prospective year, then the Company shall have sixty (60) days
to deliver such projections to the Investment Banking Firms and to the Selling
Partner and the 30-day and 40-day time periods set forth in Section 3(d)(iii)
shall be adjusted to 75-day and 85-day periods, respectively; provided, that
unless the Selling Partner so elects to have the Company prepare projections
for the Company and TWE as described in this sentence, then none of the
Investment Banking Firms shall utilize projections in determining the value of
the Offered Interest, other than projections that have previously been made
available (by the Company, analysts or otherwise) to the general public (to the
extent that such projections are relevant). The Company shall make its
executive officers available for due diligence sessions, as reasonably
requested.

                                    (f)      The consummation of any purchase
of the Offered Interest by AOLTW and/or the Company pursuant to this Section 3
shall be held at a single closing at the executive office of the Company at
11:00 a.m., local time, on a

FMV pursuant to Section 3(d) (upon at least five (5) days' notice to the
Selling Partner); provided, that such period shall be extended for 90
additional days, or such shorter period of time, as shall be necessary in order
to obtain requisite governmental or regulatory approvals with respect to such
transaction (which the parties shall use their respective commercially
reasonable efforts to obtain as promptly as practicable), or as provided in
Section 5(a); and provided further, that such closing may be held at such other
time and place as the parties to the transaction may agree. At such closing,
AOLTW and/or the Company shall, severally (with respect to itself) and not
jointly, pay to the Selling Partner the AOLTW Purchase Price and/or the Company
Purchase Price, as applicable, in respect of the portion of the Offered
Interest to be purchased by such party in any combination of (x) cash, which
shall be payable by wire transfer of immediately available funds, and (y)
validly issued, fully paid and non-assessable shares AOLTW Common Stock (in the
case of the AOLTW Purchase Price) or Time Warner Cable Common Stock (in the
case of the Company Purchase Price) (the fair market value of which will be
determined pursuant to Section 5 below) pursuant to such instruments as may be
reasonably necessary to deliver the AOLTW Common Stock or Time Warner Cable
Common Stock, as applicable, and in appropriate form for transfer, free and
clear of any lien or other encumbrance, and the Selling Partner shall, pursuant
to such instruments as may be reasonably necessary, deliver to AOLTW and/or the
Company, as applicable, the Offered Interest to be sold at such closing, in
appropriate form for transfer, free and clear of any lien or other encumbrance.

                  4.       Sale Right.

                                    (a)      Following the Transfer Date, the
Selling Partner shall have the right (the "Sale Right") to Dispose of all or
any portion of its Offered Interest to any Person pursuant to this Section 4,
so long as the Selling Partner first complies with clauses (b) through (h)
below.

                                    (b)      The Selling Partner shall give
written notice (the "Sale Notice") to AOLTW and the Company (it being
understood that no such notice may be delivered prior to the Transfer Date),
which Sale Notice shall state (i) the name of the Person (the "Prospective
Purchaser") to whom the Selling Partner wishes to Dispose of such Offered
Interest, and, if such Prospective Purchaser is a Subsidiary of another Person,
the name of the Ultimate Parent (as defined in the Partnership Agreement) of
such Prospective Purchaser, neither of which Persons may be an Affiliate of, or
otherwise acting in concert to circumvent the provisions of this Section 4
with, the Selling Partner, (ii) the price to be paid for such Offered Interest
(the "Sale Price"), which price must be payable in cash upon consummation of
such Disposition, (iii) the date on which such Disposition is scheduled to
occur and (iv) that the offer of the Prospective Purchaser was made after the
Transfer Date and has been accepted by the Selling Partner subject to the
rights of AOLTW and the Company contained in this Agreement.

                                    (c)      The Sale Notice shall be
accompanied by a certificate of the Prospective Purchaser (and, if such
Prospective Purchaser is a
<PAGE>
                                                                              9


Subsidiary of another Person, then also a certificate of the Ultimate Parent of
such Prospective Purchaser) stating that (i) its offer to purchase the Offered
Interest has been approved by its board of directors (or, if such Person is not
a corporation, the equivalent), (ii) the description of its offer contained in
the Sale Notice is complete and accurate in accordance with the requirements of
this Section 4, (iii) adequate financing arrangements have been, or are
reasonably expected to be, secured in respect of its offer, (iv) its offer is
reasonably capable of being consummated and that there are no significant
regulatory impediments to such consummation (other than any required regulatory
approval disclosed in the Sale Notice) and (v) it is aware of the rights of
AOLTW and the Company contained in this Agreement and that it is not an
Affiliate of, or otherwise acting in concert to circumvent the provisions of
this Section 4 with, the Selling Partner.

                                    (d)      For a period of fifteen (15) days
after receipt of the Sale Notice and the certificate required by Section 4(c)
above (the "AOLTW Matching Period"), AOLTW shall have the right (the "AOLTW
Matching Right") but not the obligation to elect to purchase all or any portion
of the Offered Interest at a purchase price (the "AOLTW Matching Price") equal
to (x) the percentage of the Offered Interest AOLTW proposes to purchase
multiplied by (y) the Sale Price. The AOLTW Matching Right shall be exercisable
by giving written notice (the "AOLTW Matching Notice") of the exercise thereof,
prior to the expiration of the AOLTW Matching Period, to the Selling Partner,
with a copy to the Company, which notice shall state the portion of the Offered
Interest to be purchased by AOLTW. Upon delivery of the AOLTW Matching Notice,
subject to Section 4(f) below, AOLTW shall be obligated to purchase, and the
Selling Partner shall be obligated to sell, the Offered Interest specified in
the AOLTW Matching Notice at the AOLTW Matching Price and upon the terms and
conditions set forth in the Sale Notice, except that AOLTW (or any Affiliate
thereof) shall be entitled to pay all or any portion of the AOLTW Matching
Price in shares of AOLTW Common Stock as provided in Section 5 below. The
failure of AOLTW to respond within the AOLTW Matching Period shall be deemed to
be an election by AOLTW not to purchase any of the Offered Interest and shall
be a waiver of the AOLTW Matching Right, provided that AOLTW may elect not to
purchase the Offered Interest and to waive its rights under this Section 4(d)
prior to the expiration of the AOLTW Matching Period by giving written notice
to the Selling Partner, with a copy to the Company.

                                    (e)      If AOLTW does not elect to
purchase all of the Offered Interest, then for a period of five (5) days after
the earlier to occur of (a) the expiration of the AOLTW Matching Period and (b)
the receipt of the AOLTW Matching Notice (or written notice from AOLTW of its
waiver of the AOLTW Matching Right) (the "Company Matching Period"), the
Company shall have the right (the "Company Matching Right") but not the
obligation to elect to purchase all but not less than all of the remaining
Offered Interest at a purchase price (the "Company Matching Price") equal to
(x) the percentage of the Offered Interest not purchased by AOLTW multiplied by
(y) the Sale Price. The Company Matching Right shall be exercisable by giving
written notice (the "Company Matching Notice") of the exercise thereof, prior
to the expiration of the Company Matching Period, to the Selling Partner. Upon
delivery of the Company Matching Notice, the Company shall be obligated to
purchase, and the Selling Partner

                                                                             10


shall be obligated to sell, all of such remaining Offered Interest for the
Company Matching Price and upon the terms and conditions set forth in the Sale
Notice, except that the Company (or any Affiliate thereof) shall be entitled to
pay all or any portion of the Sale Price in shares of Time Warner Cable Common
Stock as provided in Section 5 below. The failure of the Company to respond
within the Company Matching Period shall be deemed to be a waiver of the
Company Matching Right, provided that the Company Partner may waive its rights
under this Section 4(e) prior to the expiration of the Company Matching Period
by giving written notice to the Selling Partner.

                                    (f)      If AOLTW and the Company
(individually or in the aggregate) do not elect to purchase all of the Offered
Interest pursuant to Sections 4(d) and 4(e) above, the Selling Partner shall
have the right to Dispose of all but not less than all of the Offered Interest
to the Prospective Purchaser upon terms and conditions that are no more
favorable to the Prospective Purchaser with respect to the Offered Interest
than those contained in the Sale Notice; provided, that such sale is bona fide
and made within 45 days after the date of the expiration of the Company
Matching Period (as such may be extended for 90 additional days, or such
shorter period of time, as shall be necessary in order to obtain requisite
governmental or regulatory approvals with respect to such transaction). Upon
closing of any such Disposition, the Prospective Purchaser shall succeed to all
of the rights and be subject to all of the obligations of the Selling Partner
under this Agreement (including, without limitation, Sections 3 and 4 hereof)
and the Partnership Agreement.

                                    (g)      The consummation of any purchase
of the Offered Interest by AOLTW and/or the Company pursuant to this Section 4
shall be held at a single closing at the executive office of the Company at
11:00 a.m., local time, on a Business Day within 30 days following the delivery
of the Company Matching Notice (upon at least five (5) day's notice to the
Selling Partner); provided, that such period shall be extended for 90
additional days, or such shorter period of time, as shall be necessary in order
to obtain requisite governmental or regulatory approvals with respect to such
transaction (which the parties shall use their respective commercially
reasonable efforts to obtain as promptly as practicable), or as provided in
Section 5(a); and provided, further, that such closing may be held at such
other time and place as the parties to the transaction may agree. At such
closing, AOLTW and/or the Company shall, severally (with respect to itself) and
not jointly, pay to the Selling Partner the AOLTW Matching Price and/or the
Company Matching Price in respect of the portion of the Offered Interest to be
purchased by such party in any combination of (x) cash, which shall be payable
by wire transfer of immediately available funds, and (y) validly issued, fully
paid and non-assessable shares AOLTW Common Stock (in the case of the AOLTW
Matching Price) or Time Warner Cable Common Stock (in the case of the Company
Matching Price) (the fair market value of which will be determined pursuant to
Section 5 below) pursuant to such instruments as may be reasonably necessary to
deliver the AOLTW Common Stock or Time Warner Cable Common Stock, as
applicable, and in appropriate form for transfer, free and clear of any lien or
other encumbrance, and the Selling Partner shall, pursuant to such instruments
as may be reasonably necessary, deliver to AOLTW and/or
<PAGE>
                                                                             11


the Company, as applicable, the Offered Interest to be sold at such closing, in
appropriate form for transfer, free and clear of any lien or other encumbrance.

                                    (h)      If the Selling Partner does not
complete the sale of all of the Offered Interest to (x) a Prospective Purchaser
in accordance with the time period specified in Section 4(f) above (or
affirmatively waives the right to complete such sale, in writing, prior to the
expiration of such period) or (y) AOLTW and/or the Company in the time period
specified in Section 4(g) above then (other than as a result of a breach by
AOLTW or the Company of such party's obligations under this Section 4), in each
case, the provisions of this Section 4 shall again be applicable and the
Selling Partner shall again be permitted to elect to exercise either its
Appraisal Right or its Sale Right with respect to any Offered Interest, as
provided in Section 2; provided, that in the case of a failure to complete a
sale to a Prospective Purchaser (other than as a result of a breach by AOLTW or
the Company of such party's obligations under this Section 4), such selling
Partner shall not be entitled to exercise its Sale Right or Appraisal Right
until sixty (60) days after the expiration of the 45-day period referred to in
Section 4(f) (or such longer period to which such 45-day period has been
extended pursuant to Section 4(f)); provided, further, that if the Selling
Partner has waived its right to complete the sale to a Prospective Purchaser
pursuant to clause (x) above, such 60-day period shall commence on the date of
such waiver.

                  5.       Provisions Relating to Common Stock.

                                    (a)      If any portion of the purchase
price payable by AOLTW or the Company pursuant to Section 3 or 4 is to be paid
in shares of AOLTW Common Stock or Time Warner Cable Common Stock, as
applicable, then (x) the fair market value of such shares shall be deemed to be
equal to the average (rounded to the nearest 1/10,000) of the Trading Values
(as defined below) of a share of AOLTW Common Stock or Time Warner Cable Stock,
as applicable, for each of the fifteen (15) consecutive Trading Days ending two
(2) Trading Days prior to the applicable closing date, (y) any shares of Time
Warner Cable Common Stock received by the Selling Partner shall, after they are
issued to such Selling Partner, be deemed to be "Registrable Securities" held
by MediaOne (or its permitted transferee) under the Registration Rights
Agreement, dated the date hereof, among the Company, AOLTW and MediaOne
(provided that, if such Selling Partner is not then a party to such Agreement,
such shares shall only be deemed to be Registrable Securities if MediaOne
agrees to transfer all or a portion of its right thereunder to such Selling
Partner and such Selling Partner agrees to be bound by the terms and conditions
of such agreement) and (z) any shares of AOLTW Common Stock received by the
Selling Partner shall, after they are issued to such Selling Partner, have
registration rights substantially identical to the rights of MediaOne (or its
permitted transferee) under the Registration Rights Agreement, dated the date
hereof, between AOLTW and MediaOne; provided that promptly upon exercise by
AOLTW of any right to use AOLTW Common Stock as a portion of the purchase price
pursuant to Section 3 or 4, AOLTW will use all commercially reasonable efforts
to have a "shelf" registration statement declared effective as of the date the
AOLTW Common Stock is delivered pursuant hereto or as promptly thereafter as
practicable. Notwithstanding

                                                                             12


anything to the contrary in this Agreement, no shares of AOLTW Common Stock or
Time Warner Cable Common Stock, as applicable, may be delivered in full or
partial satisfaction of any purchase price payable pursuant to Section 3 or
Section 4, (A) if shares of such class are not then admitted for trading on the
NYSE or for quotation on NASDAQ or (B) if AOLTW and/or the Company, as
applicable, has not delivered to the Selling Partner written notice (a "Stock
Election Notice") setting forth (i) such party's election (which election shall
be irrevocable) to deliver such shares in full or partial satisfaction of any
such purchase price (which Stock Election Notice shall specify what portion of
the purchase price will be satisfied in shares) and (ii) the closing date
designated for the closing of such purchase, which closing date (x) shall
comply with the requirements of Section 3(f) or 4(g), as applicable and (y)
shall be no fewer than twenty (20) Trading Days subsequent to the date of such
Stock Election Notice; provided that if, as a result of events subsequent to
the delivery of the Stock Election Notice the number of Trading Days between
the date of delivery of a Stock Election Notice and the date of closing set
forth in such Stock Election Notice is fewer than twenty (20), such closing
date shall be extended to the extent necessary such that there are no fewer
than twenty (20) Trading Days between the date of such delivery and such
closing date.

                                    (b)      The parties hereto shall not, and
shall cause their respective Affiliates, agents and representatives not to,
engage in, announce an intention to engage in, or act in concert with any
Person to engage in a Prohibited Activity.

                                    (c)      For the purposes of this
Agreement, (x) the term "Trading Value" means, with respect to any AOLTW Common
Stock or Time Warner Cable Common Stock on any given Trading Day, the volume
weighted trading price (rounded to the nearest 1/10,000) of such security on
the NYSE or Nasdaq, as applicable, as reported by Bloomberg Financial Markets
(or such other source as the Selling Partner and the Company shall agree) for
that Trading Day, and (y) the term "Trading Day" means any day on which shares
of AOLTW Common Stock or the Time Warner Cable Common Stock, as applicable, are
traded on the NYSE or Nasdaq, as applicable.

                  6.       Miscellaneous.

other right, power or remedy. The rights and remedies provided for herein are
cumulative and are not exclusive of any rights and remedies that may be
available to the parties hereto at law, in equity or otherwise.

therefrom) in any such suit, action or proceeding and irrevocably waives, to

                              VALUATION GUIDELINES

(a)      Valuation of the Offered Interest will be based upon the fully
         distributed public market value of the common equity of TWE assuming
         TWE was a corporation and all such common equity was represented by a
         single class of common stock. Such valuation will be determined
         without regard to offering discounts or any discount in respect of
         liquidity, corporate structure (including, without limitation, the
         fact that TWE is a partnership and that the stake is a minority
         interest) or tax liability from any allocation of taxable income in
         respect of the Offered Interest, and will assume, notwithstanding any
         facts to the contrary, that TWE is not to be liquidated in the near
         future; provided that if TWE is in fact in the process of being
         liquidated or is to be liquidated in the near future, the valuation
         shall take into account any economic circumstances leading to such
         liquidation.

(b)      Any debt and preferred equity of TWE or any comparable company will be
         measured at book value for purposes of preparing the valuation.

(c)      The appraisers will rely on the current public trading values of a
         group of not more than 3 companies which are comparable to TWE
         (businesses engaged in the same business, with similar scale, credit
         quality and capital structures).

(d)      For purposes of determining a cable-only multiple, the value of the
         non-cable assets shall be determined as the amount reflected in the
         relevant company's publicly traded share price as a result of the
         ownership of such assets.

(e)      In calculating the value, the appraisers shall disregard any
         guarantees by TWE or its Subsidiaries of debt or other obligations of
         the Company or any of its Subsidiaries or by the Company or any of its
         Subsidiaries of debt or other obligations of TWE or its Subsidiaries.
