2. PURCHASE AND SALE OF ASSETS; ASSUMED OBLIGATIONS AND LIABILITIES.

      2.1. Purchase and Sale of Assets. Subject to the terms and conditions set

following (the "Assumed Obligations and Liabilities"): (a) those obligations and
liabilities accruing and relating to periods after the Closing Time under or
with respect to the Assets assigned and transferred to Buyer at the Closing; (b)
those obligations and liabilities of Seller to subscribers and customers of
Seller's Business for (i) subscriber deposits held by Seller as of the Closing
Date related to the Systems in the amount for which Buyer received credit under
Section 3.2 and (ii) customer, advertising and other advance payments held by
Seller as of the Closing Date related to the Systems in the amount for which
Buyer received credit under Section 3.2; (c) all obligations and liabilities
accruing and relating to the Business prior to the Closing Time in respect of
which Buyer received a credit pursuant to Section 3.2; and (d) all other
obligations and liabilities accruing and relating to periods after the Closing
Time and arising out of Buyer's ownership of the Assets or operation of the
Systems after the Closing Time, except to the extent that such obligations or
liabilities relate to any Excluded Asset. All obligations and liabilities,
contingent, fixed or otherwise, arising out of or relating to the Assets or the
Systems other than the Assumed Obligations and Liabilities will remain and be
the obligations and liabilities of Seller (collectively, the "Excluded
Liabilities").

3. CONSIDERATION.

      3.1. Purchase Price. Buyer will pay to Seller for the Assets total cash
consideration of $1,450,000,000, subject to adjustment as provided in Section
3.2 (the "Estimated Purchase Price").

immediately available funds pursuant to wire instructions delivered by Seller to
Buyer no later than two Business Days prior to the Closing Date, cash in an

Price"). For purposes of this Agreement, the "Retained Franchise Amount" for a
Retained Franchise shall be equal to the number of Equivalent Basic Subscribers
served by Seller pursuant to such Retained Franchise multiplied by the
Subscriber Adjustment Amount.

            3.1.2. Upon any transfer of a Retained Franchise to Buyer after the

such Retained Franchise by wire transfer of immediately available funds.


                                       10
<PAGE>

      3.2. Adjustments to Purchase Price. The Purchase Price will be adjusted as
follows:

            3.2.1. Adjustments on a pro rata basis as of the Closing Time will
be made for all prepaid expenses (other than inventory), accrued expenses
(including real and personal property Taxes), copyright fees and franchise or
license fees or charges, prepaid income, subscriber prepayments and accounts
receivable related to the Business, all as determined in accordance with GAAP
consistently applied, and to reflect the principle that all expenses and income
attributable to the Business for the period through and including the Closing
Time are for the account of Seller, and all expenses and income attributable to
the Business for the period after the Closing Time are for the account of Buyer.
Notwithstanding the foregoing, with respect to accounts receivable resulting
from cable television services or Internet access or high speed data services,
the Purchase Price will be increased by (a) 100% of the face amount of such
accounts receivable that are 30 days or less past due as of the Closing and (b)
95% of the face amount of such accounts receivable that are 31 to 60 days past
due as of the Closing; provided, however, that Seller will receive no credit for
any accounts receivable resulting from cable television services or Internet
access or high speed data services of which more than the lesser of (A) $10.00
or (B) the standard rate for Basic Service is more than 60 days past due as of
the Closing Date. With respect to accounts receivable resulting from advertising
sales, the Purchase Price will be increased by 100% of the face amount of such
accounts receivable that are less than 120 days past due as of the Closing, and
Seller will receive no credit for any accounts receivable resulting from
advertising sales of which any portion is 120 days or more past due as of the
Closing Date. For purposes of making "past due" calculations for cable
television services or Internet access or high speed data services, the billing
statements of a System will be deemed to be due and payable on the first day of
the period during which the service to which such billing statements relate is
provided.

            3.2.2. All advance payments to, or funds of Third Parties on deposit
with, Seller as of the Closing Time and relating to the Business, including
advance payments and deposits by subscribers served by the Business for
converters, encoders, decoders, cable modems, cable television services and
related sales, will be assumed by and credited to the account of Buyer.

            3.2.3. There will be credited to Buyer the economic value of all
accrued vacation time that Buyer credits after the Closing Time to Hired
Employees pursuant to Section 6.3, where economic value is the amount equal to
the cash compensation that would be payable to each such Hired Employee at his
or her level of compensation on the Closing Date for a period equal to such
credited accrued vacation.

            3.2.4. All deposits relating to the Business and the operation of
the Systems that are held by Third Parties as of the Closing Time for the
account of Seller which relate to the Systems or are held as security for
Seller's performance of Assumed Obligations and Liabilities, including deposits
on leases and deposits for utilities, will be credited to the account of Seller
in their full amounts and will become the property of Buyer. All other deposits
will remain the property of Seller.


                                       11

            3.2.5. The Purchase Price will be increased by an amount equal to
the capital expenditures made by Seller or Affiliates of Seller between the date
of this Agreement and the Closing Date at the specific written request of Buyer,
and which Seller is not otherwise required to make pursuant to the terms of this
Agreement, as contemplated by Section 6.2.2. The Purchase Price will be
decreased by the amount, if any, by which Seller fails to make any capital
expenditures that Seller is required to make pursuant to Section 6.2.2 of this
Agreement.

            3.2.6. The Purchase Price will be decreased by the dollar amount
equal to the product of (a) the Subscriber Shortfall multiplied by (b) the
Subscriber Adjustment Amount. For purposes of this Agreement, the "Subscriber
Shortfall" equals the number, if any, by which the Equivalent Basic Subscribers
of the Systems at the Closing is less than the Subscriber Threshold.

            3.2.7. The Purchase Price shall be increased or decreased as
otherwise provided herein or as agreed to by the parties in accordance with the
provisions of this Agreement.

            3.2.8. The adjustments provided for in this Section 3.2 will be made
without duplication. In addition, none of the adjustments provided for in this
Section 3.2 will be made with respect to any Excluded Asset or Excluded
Liability or with respect to any item of income or expense related to an
Excluded Asset or Excluded Liability.

            3.2.9. The net amount of the adjustments calculated under this
Section 3.2, as preliminarily determined pursuant to Section 3.3.1, will be
added or subtracted, as applicable, to the Purchase Price at the Closing.

      3.3. Determination of Adjustments. Preliminary and final adjustments to
the Purchase Price will be determined as follows:

            3.3.1. Not later than a date Seller reasonably believes is at least
15 Business Days prior to the Closing, Seller will deliver to Buyer a report
(the "Preliminary Adjustments Report"), certified by Seller, showing in detail
the preliminary determination of the adjustments referred to in Section 3.2,
which have been calculated as of the Closing Time (or as of any other date and
time agreed by the parties) and any documents substantiating the adjustments
proposed in the Preliminary Adjustments Report. Buyer will have 10 Business Days
following receipt of the Preliminary Adjustments Report to review such Report
and supporting information and to notify Seller of any disagreements of Buyer
with Seller's estimates. If Buyer provides a notice of disagreement with
Seller's estimates of the adjustments referred to in Section 3.2 within such 10
Business Day period, Buyer and Seller will negotiate in good faith to resolve
any such dispute and to reach an agreement prior to the Closing Date on such
estimated adjustments as of the Closing Time. The basis for determining the
Purchase Price to be paid at the Closing will be (a) the estimate so agreed upon
by Buyer and Seller or (b) if the parties do not reach such an agreement on the
estimated amount of the adjustments set forth in the Preliminary Adjustments
Report prior to the


                                       12
<PAGE>

Closing Date or if Buyer fails to provide a notice of disagreement with Seller's
estimates of such adjustments within the requisite time provided, the estimates
of such adjustments set forth in the Preliminary Adjustments Report.

            3.3.2. Within 90 days after the Closing Date, Seller will deliver to
Buyer a report (the "Final Adjustments Report") certified by Seller showing in
detail the final determination of all adjustments which were not calculated as
of the Closing Time and containing any corrections to the Preliminary
Adjustments Report, together with any documents substantiating the adjustments
proposed in the Final Adjustments Report. Buyer will provide Seller with
reasonable access to all records that Buyer has in its possession and which are
necessary for Seller to prepare the Final Adjustments Report.

            3.3.3. Within 30 days after receipt of the Final Adjustments Report,
Buyer will give Seller written notice of Buyer's objections, if any, to the
Final Adjustments Report. If Buyer timely makes any such objection, the parties
will agree on the amount, if any, which is not in dispute within 30 days after
Seller's receipt of Buyer's notice of objections to the Final Adjustments
Report, and payment of the amount not in dispute will be made by the responsible
party by wire transfer of immediately available funds within three Business Days
after such agreement. Any disputed amounts will be determined by a national
accounting firm agreed to by Buyer and Seller which has not provided services to
Buyer, Seller or their respective Affiliates in the prior 12 months, which firm
will be obligated to determine such amounts within 90 days after the dispute is
submitted to it, and the determination of which will be conclusive. Seller and
Buyer will bear equally the fees and expenses payable to such firm in connection
with such determination. The responsible party will make the payment required
after determination of all disputed amounts by wire transfer of immediately
available funds to the other party within three Business Days after the final
determination of all disputed items.

      3.4. Allocation of Purchase Price. The consideration payable by Buyer
under this Agreement will be allocated among the Assets as set forth in a
schedule prepared by an independent appraiser with significant experience in the
cable television industry. Such appraiser will be selected by Buyer and will be
instructed to complete such schedule not later than 45 days after the Closing
Date. The fees of such appraiser will be the responsibility solely of Buyer.
Buyer and Seller agree to be bound by the allocation and will not take any
position inconsistent with such allocation and will file all returns and reports
with respect to the transactions contemplated by this Agreement, including all
federal, state and local Tax returns, on the basis of such allocation.

action of any kind with respect to or otherwise affecting the Assets or the

the Systems or would materially adversely affect the ability of Seller to
perform its obligations under this Agreement or the Transaction Documents.

notice of, nor does Seller have any Knowledge of, any deficiency, assessment or
audit, or proposed deficiency, assessment or audit from any taxing Governmental
Authority which could affect or result in the imposition of an Encumbrance upon
the Assets.

capital expenditures required with respect to the specific capital projects
disclosed on Schedule 6.2.2; (c) make any capital expenditures required to

generally applicable to cable systems owned and operated by AT&T, including with
respect to the make and model of such converter boxes and modems.

            6.2.3. Seller will maintain the Assets in good repair, order and
condition (ordinary wear and tear excepted), will maintain in full force and
effect, policies of insurance with respect to the Business in such amounts and
covering such risks as customarily maintained by operators of cable television

maintain its books, records and accounts in the ordinary manner on a basis
consistent with past practices. Seller will (a) only report and write off

due all Taxes relating to System Employees, the Assets or the System, (c)
maintain service quality of the Systems at a level at least consistent with past
practices, (d) file with the FCC all reports required to be filed under

            6.2.4. Seller will not, except as disclosed on Schedule 6.2: (a)
sell, transfer or assign any material portion of the Assets other than sales in
the ordinary


                                       24

course of business; (b) modify, renew, terminate, suspend or abrogate any
Franchises, Licenses or material Contracts (other than those constituting
Excluded Assets); (c) enter into any non-ordinary course Contract or commitment

accordance with an AT&T-wide plan or program (in which case Seller will give
prior notice to Buyer) or where required by any Legal Requirement; (i) decrease
the rate charged for any level of Basic Service, Expanded Basic Service or any
Pay TV, except to the extent required by any Legal Requirement; and (j) solicit
any Person to subscribe to any services of the Business other than in the
ordinary course of business and consistent with past practices, which shall
include promotions or offers of discount of the type disclosed on Schedule 4.16;
provided, however, that notwithstanding the foregoing, from and after the date
of this Agreement, Seller shall not solicit any Person to subscribe to (or offer
to any Person to retain such Person as a subscriber to) any services of the
Business in any manner which, directly or indirectly, involves the compromise,
write-off or release of any amount due for services previously rendered to such
Person by Seller.

            6.2.5. Seller will deliver to Buyer, within 20 days following the
end of each month prior to the Closing Date, the following unaudited financial
reports (by GL number) for the prior month: "New System P&L (expanded)" report,
"Field P&L" report, a capital expenditure summary, and a summary installation
and disconnect activity report to include Equivalent Basic Subscribers
(calculated in a manner consistent with Schedule 4.16) digital subscribers and
@Home subscribers, and such other financial reports that Seller regularly
prepares in the ordinary course of business as Buyer may reasonably request. All
financial reports so delivered will present fairly and accurately, in all
material respects, the financial condition and results of operations of the
Business for the period of such report and will be prepared in accordance with
GAAP on a basis consistent with the Financial Statements except as otherwise
noted therein. Further, Seller will deliver to Buyer CSG reports CPRM-006 and
CPSM-318 with respect to the Systems for January and March 2001 within 30 days

                                       25
<PAGE>

      6.3. Employee Matters. Buyer may, but shall have no obligation to, employ
or offer employment to any of the System Employees. All employment-related
matters relating to System Employees arising from and after the date of this
Agreement will be handled in such manner as Buyer and Seller agree.

      6.4. Leased Vehicles and Other Capital Leases. Seller will pay the
remaining balances on any leases for vehicles or capital leases included in the
Equipment and will deliver title to such vehicles and other Equipment free and
clear of all Encumbrances (other than Permitted Encumbrances) to Buyer at the
Closing.

      6.5. Consents.

            6.5.1. Prior to the Closing, Seller will use commercially reasonable
efforts to obtain in writing, as promptly as possible and at its expense, all
the Required Consents, in form and substance reasonably satisfactory to Buyer
and will deliver to Buyer copies of such Required Consents promptly after they
are obtained by Seller. Buyer will cooperate with Seller to obtain all Required
Consents, but Buyer will not be required to accept or agree or accede to any
modifications or amendments to, or changes in, or the imposition of any
condition to the transfer to Buyer of any Contract, Franchise, License or other
Governmental Permit that are not reasonably acceptable to Buyer. Notwithstanding
the foregoing, Buyer will comply with the reasonable requests of Seller and, to
the extent required, negotiate in good faith with any Third Party, as necessary
for Seller to assign to Buyer in part the rights and obligations under any
master Contract disclosed on Schedule 4.6.

            6.5.2. Notwithstanding the provisions of Section 6.5.1, Seller will
not have any further obligation to obtain Required Consents: (a) with respect to
Contracts relating to pole attachments where the licensing party will not, after
Seller's exercise of commercially reasonable efforts, consent to an assignment
of such Contract but requires that Buyer enter into a new agreement with such
licensing authority, in which case Buyer will use its commercially reasonable
efforts to enter into such agreement prior to the Closing or as soon as
practicable thereafter and Seller will cooperate with and assist Buyer in
obtaining such agreements; (b) for any business radio license which Seller
reasonably expects can be obtained within 120 days after the Closing and so long
as a temporary authorization is available to Buyer under FCC rules with respect
thereto and Seller has reasonably cooperated in the filing of assignment
applications prior to the Closing; and (c) with respect to leased Real Property,
if Seller obtains and makes operational prior to the Closing substitute leased
Real Property that is reasonably satisfactory to Buyer.

            6.5.3. Buyer and Seller will mutually agree upon their respective
obligations with respect to, and ultimate disposition of, any Retained
Franchise.

            6.5.4. Subject to receiving information necessary from Buyer, Seller
will execute and use commercially reasonable efforts to deliver all required FCC
Forms 394 to the appropriate Governmental Authorities on or before February 28,
2001.


                                       26
<PAGE>

      6.6. Title Commitments and Surveys. After the execution of this Agreement,
Buyer may obtain, at its sole expense, (a) commitments for owner's title
insurance policies (and if Buyer decides to do so, title insurance) on some or
all Real Property owned by Seller and on easements which provide access to each
such parcel of Real Property, and (b) an ALTA survey on each parcel of Real
Property for which a commitment for a title insurance policy is to be obtained.
Seller will provide reasonable assistance in connection with Buyer obtaining
such commitments (and title insurance) and surveys, as Buyer may request from
time to time (including delivering such affidavits and other documents that the
title company or Buyer may reasonable request in order to cause the title
company to issue title insurance in favor of Buyer). Without limiting the
foregoing, Seller will as soon as practicable after the execution of this
Agreement deliver to Buyer such information as shall be reasonably necessary to
permit Buyer to order commitments for title insurance on Real Property owned by
Seller and Buyer will promptly after receipt of such information order such
commitments. If Buyer notifies Seller in writing that the commitment or survey
discloses a defect in title that constitutes a breach, or any facts which could
be reasonably expected to result in a breach, of the representations of Seller
contained in Section 4.7, then Seller will promptly commence further
investigation and use commercially reasonable efforts to, at its expense, cure
the defect prior to the Closing. If Seller, having used such commercially
reasonable efforts, is unable to cure the defect prior to the Closing and the
Closing occurs, then (i) Buyer and Seller may enter into a written agreement at
the Closing mutually acceptable to both parties with respect to Seller's
obligation to cure such defect after the Closing, and (ii) any claim for
indemnification that Buyer may have with respect to the defect may be brought
without the requirement that such claims meet or exceed the Threshold Amount.

      6.7. HSR Notification. As soon as practicable after the execution of this
Agreement, but in any event no later than 30 days after such execution, Seller
and Buyer will each complete and file, or cause to be completed and filed, any
notification and report required to be filed under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended (the "HSR Act"); and each such
filing will request early termination of the waiting period imposed by the HSR
Act. Each party will bear its own costs incurred with respect to such filings.
The parties will use their commercially reasonable efforts to respond as
promptly as reasonably practicable to any inquiries received from the Federal
Trade Commission (the "FTC") and the Antitrust Division of the Department of
Justice (the "Antitrust Division") for additional information or documentation
and to respond as promptly as reasonably practicable to all inquiries and
requests received from any other Governmental Authority in connection with
antitrust matters. The parties will use their respective commercially reasonable
efforts to overcome any objections which may be raised by the FTC, the Antitrust
Division or any other Governmental Authority having jurisdiction over antitrust
matters. Notwithstanding the foregoing, neither Buyer nor Seller will be
required to make any significant change in the operations or activities of their
respective business (or any material assets employed therein) or that of any of
their respective Affiliates, if such party determines in good faith that such
change would be materially adverse to the operations or activities of such
business (or any material assets employed therein), provided such business has
significant assets, net worth, or revenue. Each of Buyer and


                                       27
<PAGE>

Seller will coordinate with the other with respect to its filings and will
cooperate to prevent inconsistencies between their respective filings and will
furnish to each other such necessary information and reasonable assistance as
the other may reasonably request in connection with its preparation of necessary
filings or submissions under the HSR Act.

      6.8. Notification of Certain Matters. Seller will promptly notify Buyer of
any fact, circumstance, event or action by it or otherwise (a) which, if known
at the date of this Agreement, would have been required to be disclosed in or
pursuant to this Agreement or (b) the existence, occurrence or taking of which
would result in any of Seller's representations and warranties in this Agreement
or any Transaction Document not being true, complete and correct in all material
respects when made or at the Closing. Seller will further notify Buyer of (i)
any construction programs that Seller becomes aware are undertaken, or proposed
or threatened to be undertaken, by any municipality or other cable television,
multichannel multipoint distribution systems or multipoint distribution system
provider or operator in any franchise area served by the System and (ii) any
cable television franchise or other application or request of any Person for a
cable television franchise that Seller becomes aware has been submitted or
threatened or proposed which relates to any Service Area.

      6.9. Risk of Loss; Condemnation.

            6.9.1. Seller will bear the risk of any loss or damage to the Assets
resulting from fire, theft or other casualty (except reasonable wear and tear)
at all times prior to the Closing. If any such loss or damage is so substantial
as to prevent normal operation of any material portion of the Systems or the
replacement or restoration of the lost or damaged property within 45 days after
the occurrence of the event resulting in such loss or damage, Seller will
immediately notify Buyer of that fact and Buyer, at any time within 10 days
after receipt of such notice, may elect by written notice to Seller either (a)
to waive such defect and proceed toward consummation of the transactions
contemplated by this Agreement in accordance with terms of this Agreement or (b)
terminate this Agreement. If Buyer elects so to terminate this Agreement, Buyer
and Seller will be discharged of any and all obligations hereunder. If Buyer
elects to consummate the transactions contemplated by this Agreement
notwithstanding such loss or damage and does so, there will be no adjustment in
the consideration payable to Seller on account of such loss or damage (other
than the amount of any insurance deductible), but all insurance proceeds payable
as a result of the occurrence of the event resulting in such loss or damage will
be delivered by Seller to Buyer, or the rights to such proceeds will be assigned
by Seller to Buyer if not yet paid over to Seller.

            6.9.2. If, prior to the Closing, all or any portion of the Assets
are taken or condemned as a result of the exercise of the power of eminent
domain (which shall not be deemed to include the exercise of any right of first
refusal in any Franchise), or if a Governmental Authority having such power
seeks to condemn a portion of the Assets by proper statutory process (such event
being called, a "Taking"), then Seller will promptly so notify Buyer and Buyer
may, by giving notice to Seller within 10 days of receiving notice of the
Taking, elect, in the name of Seller, to


                                       28
<PAGE>

negotiate for, claim, contest and receive all damages with respect to the
Taking. If Buyer so elects, (a) Seller will be relieved of its obligation to
convey to Buyer the Assets or interests that are the subject of the Taking, (b)
at the Closing, Seller will assign to Buyer all of the Seller's rights
(including the right to receive payment of damages) with respect to the Taking
and will pay to Buyer all damages previously received by Seller with respect to
the Taking, and (c) following the Closing, Seller will give the Buyer such
further assurances of such rights and assignment with respect to the Taking as
may from time to time reasonably request. If the portion of the Assets subject
to such Taking is material to the operation of the Business or the Systems,
taken as a whole, Buyer may elect to terminate this Agreement with no liability
to Seller.

      6.10. Transfer Taxes. Any state or local sales, use, transfer, or
documentary transfer Taxes or fees or any other charge imposed by any
Governmental Authority (other than any of Seller's income, franchise, gross
receipts, corporation, excess profits, rental, devolution, or payroll tax by
whatsoever authority imposed or howsoever designated) arising from or payable by
reason of the transfer of the Assets contemplated by this Agreement will be
shared equally by Buyer and Seller.

      6.11. Updated Schedules. Not less than 10 Business Days prior to the
projected Closing Date, Seller will deliver to Buyer revised copies of each of
the Schedules, except for Schedules 4.15 and 4.16, in each case updated and
marked to show any changes occurring between the date of this Agreement and the
date of delivery; provided, however, that for purposes of Seller's
representations and warranties and covenants in this Agreement, all references
to the Schedules will mean the version of the Schedules attached to this
Agreement on the date of signing, and provided, further, that if the effect of
any such updates to Schedules is to disclose any one or more additional
properties, privileges, rights, interests or claims not included on the
Schedules as of the date of this Agreement, Buyer will have the right (to be
exercised by written notice to Seller at or before the Closing) to cause any one
or more of such items to be designated as and deemed to constitute Excluded
Assets for all purposes under this Agreement unless such items are Contracts
that were not required to be scheduled or that were entered into after the date
of this Agreement in accordance with the terms of this Agreement.

      6.12. Use of Seller's Name. Seller and its Affiliates will retain all
rights with respect to the names "AT&T," "Tele-Communications, Inc." and "TCI"
or any and all derivations thereof after the Closing. Buyer will remove or
delete such names or any and all derivations thereof from the Business and
Assets as soon as reasonably practicable, but in any event by the 120th day
following the Closing. Notwithstanding the foregoing, nothing in this Section
6.12 will require Buyer to remove or discontinue using any such name or mark
that is affixed to converters or other items in consumer homes or properties on
the Closing Date, or as are used in a similar fashion which makes such removal
or discontinuation impracticable, provided that Buyer makes a reasonable effort
to request and provides necessary materials to enable subscribers to cover or
remove names and marks affixed to such converters and other items.


                                       29
<PAGE>

      6.13. Transitional Billing Services. Seller will provide to Buyer, upon
request, access to and the right to use its billing system computers, software
and related fixed assets ("Transitional Billing Services") in connection with
the System for a period of up to 180 days following the Closing to allow for
conversion of existing billing arrangements. Buyer will notify Seller at least
30 days prior to the Closing as to whether it desires Transitional Billing
Services from Seller. Buyer will reimburse Seller for all direct expenses
incurred by Seller in providing the Transitional Billing Services.

      6.14. Transition of High Speed Data Services; Other Transitional Matters.
Seller and Buyer will cooperate in good faith to establish a mutually agreeable
plan to allow for the conversion of high speed data customers from Seller to
Buyer. Seller will take such action as Buyer reasonably requests with respect to
such conversion, and Buyer will reimburse Seller for all direct expenses
incurred by Seller in complying with such requests. Between the date of this
Agreement and the Closing, Seller and Buyer will further cooperate in good faith
with respect to such other matters as necessary to provide for the orderly
transition of the Business from Seller to Buyer at the Closing.

      6.15. Certain Notices. Seller will duly and timely file a valid request to
invoke the formal renewal provisions of Section 626(a) of the Communications Act
with the appropriate Governmental Authority with respect to all Franchises of
the Business that will expire within 35 months after any date between the date
of this Agreement and the Closing Date.

      6.16. Satisfaction of Conditions. Each party will use commercially
reasonable efforts to satisfy, or to cause to be satisfied, the conditions to
the obligations of the other party to consummate the transactions contemplated
by this Agreement, as set forth in Section 7, as soon as practicable and in
order to permit the Closing to occur on or prior to the Target Closing Date.

      6.17. Bulk Transfers. Buyer and Seller each waive compliance by the other
with Legal Requirements relating to bulk transfers that may be applicable to the
transactions contemplated hereby.

      6.18. Programming Matters.

            6.18.1. Buyer will execute and deliver to Seller such documents as
may be reasonably requested by Seller to comply with the requirements of its
programming Contracts and channel line-up requirements with respect to
divestitures of cable television systems (other than agreements to assume such
programming Contracts or make any payments or commitments or assume any
obligations thereunder). Seller will execute and deliver such documents as may
be reasonably requested by Buyer to comply with the requirements of its
programming Contracts and channel line-up requirements with respect to
acquisitions of cable television systems. Neither party will be required to make
any payments to the other's programmers in the fulfillment of its obligations
under this Section 6.18.


                                       30
<PAGE>

            6.18.2. Seller will reasonably cooperate with Buyer, at Buyer's
request, in connection with Buyer's efforts to (a) negotiate with programming
providers with respect to on-going support provided by such programmers for
programming services carried by the Systems, and (b) obtain carriage agreements
with respect to digital programming services provided by the Systems that Buyer
intends to continue to offer after the Closing.

      6.19. Cooperation as to Rates and Fees.

            6.19.1. After the Closing, notwithstanding the terms of Section
10.4, Buyer will have the right at its own expense to assume control of the
defense of any rate proceeding with respect to the Systems that remains pending
as of the Closing or that arises after the Closing but relates to the
pre-Closing operation of the Systems; provided that Seller may complete the
pending AT&T Late Fee Settlement and the defense of such litigation as it
relates to the Systems will not be turned over to Buyer. Buyer will promptly
notify Seller regarding the commencement of any such rate proceeding relating to
the pre-Closing operation of the Systems. In any such rate proceeding involving
the Systems, Seller will cooperate in such proceeding and promptly deliver to
Buyer all information reasonably requested by Buyer as necessary or helpful in
such proceeding.

                  (a) If Buyer elects to assume control of the defense of any
      such rate proceeding, then (i) Seller will have the right to participate,
      at its expense, in the defense in such rate proceeding, and (ii) Buyer
      will have the right to settle any rate proceeding relating to the
      pre-Closing operation of the Systems unless under such settlement Seller
      would be required to bear liability with respect to the pre-Closing time
      period, in which event such settlement will require Seller's prior written
      consent, which consent will not be unreasonably withheld, conditioned or
      delayed.

                  (b) If Buyer does not elect to assume control of the defense
      of any such rate proceeding, then (i) Buyer will have the right to
      participate, at its expense, in the defense in such rate proceeding, and
      (ii) without the prior consent of Buyer (which will not be unreasonably
      withheld, conditioned or delayed), Seller will not settle such rate
      proceeding if such settlement would require Buyer to bear any liability or
      would adversely affect the rates to be charged by Buyer. In any such rate
      proceeding involving the Systems, Buyer will cooperate in such proceeding
      and promptly deliver to Seller all information in its possession that is
      reasonably requested by Seller as necessary or helpful in such proceeding.

            6.19.2. If Seller is required, following the Closing, pursuant to
any Legal Requirement, settlement or otherwise, including the AT&T Late Fee
Settlement, to reimburse or provide in-kind or another form of consideration to
any subscribers of the Systems in respect of any subscriber payments previously
made by them, including fees for cable television service, late fees and similar
payments, Buyer agrees that it will make such reimbursement or provide such
in-kind or other form of consideration


                                       31
<PAGE>

through Buyer's billing system on terms specified by Seller, and Seller will
reimburse Buyer for all such payments and other consideration made by Buyer
following the Closing and for Buyer's reasonable out-of-pocket expenses incurred
in connection therewith. Such reimbursement will be reflected in the Final
Adjustments Report, to the extent then known. For expenses incurred after
completion of the Final Adjustments Report, Seller will reimburse Buyer within
60 days after receipt of a statement therefor. Buyer will provide Seller with
all information in Buyer's possession that is reasonably required by Seller in
connection with such reimbursement.

      6.20. Cooperation on Pending Litigation. With respect to any defense or
prosecution of any litigation or legal proceeding with respect to the Systems
that relates to the period prior to the Closing Time and for which Seller and
its Affiliates are responsible pursuant to this Agreement, Buyer will cooperate
with and assist Seller and its Affiliates, upon reasonable request, by making
witnesses available and providing all information in its possession (including,
upon reasonable advance notice, access to employees with information regarding
such proceedings and access to books and records that may relate to the
proceedings, in each case without interfering in any material respect with the
conduct of Buyer's business) that Seller and its Affiliates may reasonably
require in connection with such litigation or legal proceedings or in response
to any complaint, claim, inquiry, order or requirements of any Governmental
Authority or other Third Party.

      6.21. Confidentiality.

            6.21.1. Neither Buyer nor Seller will, nor will it permit any of its
Affiliates to, issue any press release or make any other public announcement or
any oral or written statements to Seller's employees concerning this Agreement
or the transactions contemplated hereby except as required by applicable Legal
Requirements, without the prior written consent of the other party. Each party
will hold, and will cause its employees, consultants, advisors and agents to
hold, the terms of this Agreement in confidence; provided that (a) such party
may use and disclose such information once it has become publicly disclosed
(other than by such party in breach of its obligations under this Section) or
which rightfully has come into the possession of such party (other than from the
other party) and (b) to the extent that such party may be compelled by Legal
Requirements to disclose any of such information, but the party proposing to
disclose such information will first notify and consult with the other party
concerning the proposed disclosure, to the extent reasonably feasible. Each
party also may disclose such information to employees, consultants, advisors,
agents and actual or potential lenders or investors whose knowledge is necessary
to facilitate the consummation of the transactions contemplated by this
Agreement. The obligation by either party to hold information in confidence
pursuant to this Section will be satisfied if such party exercises the same care
with respect to such information as it would exercise to preserve the
confidentiality of its own similar information.

            6.21.2. All information concerning the Business or Assets obtained
by Buyer or its Affiliates pursuant to or in connection with negotiation of this
Agreement will be used by Buyer and its Affiliates solely for purposes related
to this Agreement


                                       32
<PAGE>

and, in the case of nonpublic information, will, except as may be required for
the performance of this Agreement or by Legal Requirement, be kept in strict
confidence by Buyer and its Affiliates in accordance with the terms of the
letter agreement dated October 24, 2000, which letter agreement is hereby
incorporated in this Agreement by reference. Any breach of such letter agreement
will be deemed a material breach of this Agreement.

      6.22. Lien Searches. Promptly after the Effective Date, Seller will
provide to Buyer copies of Requests for Information or Copies (Form UCC-11) (or
a similar search report acceptable to Buyer) (each, a "Lien Search") listing all
judgments and tax liens, and all effective financing statements with respect to
any of the Assets, which name as debtor either Seller, any of its Affiliates
which operate cable television businesses in each Service Area for which the
respective Lien Search is made, AT&T Broadband, LLC, or Tele-Communications,
Inc.. Seller will exercise commercially reasonable efforts to remove
Encumbrances (other than a Permitted Encumbrance or an Encumbrance which will be
terminated or released at or prior to the Closing) prior to the Closing. If such
Encumbrance cannot be removed prior to the Closing and if Buyer elects to waive
such Encumbrance and proceed towards consummation of the transaction in
accordance with this Agreement (such election to proceed to be exercised by
Buyer in its reasonable discretion), Buyer and Seller will enter into a written
agreement at the Closing containing the commitment of Seller to use commercially
reasonable efforts to remove the Encumbrance following the Closing on terms
satisfactory to Buyer in its reasonable discretion or such other agreement
mutually acceptable to the parties.

      6.23. No Solicitation. Between the date of this Agreement and the Closing
Date, Seller will not, and will cause its respective shareholders, officers,
directors, employees, agents and representatives not to, initiate, solicit or
encourage, directly or indirectly, any inquiries or the making of any proposal
with respect to the Systems or the Business, engage in any negotiations
concerning, or provide to any other Person any information or data relating to
the Systems, the Assets, or Seller for the purposes of, or have any discussions
with any Person relating to, or otherwise cooperate in any way with or assist or
participate in, facilitate or encourage, any inquiries or the making of any
proposal which constitutes, or may reasonably be expected to lead to, any effort
or attempt by any other Person to seek or effect a sale directly or indirectly
of all or substantially all of the Assets, the Systems or the Business.

      6.24. Systems' Financial Statements. Seller will use commercially
reasonable efforts to deliver to Buyer (a) audited consolidated financial
statements for the Business for the years ended December 31, 1998, 1999 and
2000, not later than April 17, 2001, and (b) unaudited consolidated financial
statements for the three months ended March 31, 2001, not later than May 1,
2001, all in a form conforming to SEC rules. All accounting costs and fees
incurred by reason of the preparation of such financial statements will be borne
by Buyer. Seller hereby consents to (i) the inclusion by Buyer of the Systems'
financial statements, if required to be so included by Buyer, in any report
required to be filed by Buyer with the Securities and Exchange Commission
("SEC"), National Association of Securities Dealers' Automated Quotations

("NASDAQ") System or any stock exchange pursuant to applicable law, rule or
regulation, including the Securities Act of 1933, as amended, or the Securities
Exchange Act of 1934, as amended, and (ii) the disclosure by Buyer of the
Systems' financial statements to Buyer's public and private debt and equity
financing sources. Seller will request, and use commercially reasonable efforts
at no out-of-pocket cost to Seller to obtain, the consent of the independent
public accountants of Seller to the inclusion of the Systems' financial
statements in any report required to be filed by Buyer with the SEC, NASDAQ
System or stock exchange.

      6.25. Environmental Assessments.

            6.25.1. Buyer may, at its sole expense, commission a qualified
engineering firm to conduct an assessment in accordance with ASTM Standard
E1527-00, and including an evaluation for asbestos and asbestos containing
materials, with respect to any or all owned parcels of Real Property. If Buyer
notifies Seller in writing as soon as is reasonably practicable after the date
Buyer receives the assessment with respect to a parcel of owned Real Property
that the assessment discloses an environmental condition that (a) constitutes a
breach, or could be reasonably expected to result in a breach, of the
representations of Seller contained in Section 4.8 or (b) could reasonably be
expected to impair the use or value of such Real Property for the continued
operations of the Business or subject Buyer to any Losses if Buyer consummates
this Agreement, then Seller shall promptly commence further investigation and
use commercially reasonable efforts at its expense to cure the condition prior
to the Closing, provided that Seller shall have no obligation to spend more than
$25,000,000 (the "Maximum Remediation Amount") in the aggregate in its attempt
to cure all such conditions. If Seller exercises its right not to cure such
conditions because the aggregate cost would exceed the Maximum Remediation
Amount, Buyer may (a) terminate this Agreement with no cost or obligation on the
part of Buyer, or (b) waive the obligation to cure, in which event Buyer will
receive a credit at the Closing in the amount, if any, by which the Maximum
Remediation Amount exceeds the aggregate amount paid by Seller to third parties
in connection with curing such conditions, and Buyer will assume all liabilities
and obligations in connection with such conditions. If the foregoing is
inapplicable because (i) the aggregate amount to cure all conditions does not
exceed the Maximum Remediation Amount or (ii) Seller does not exercise its right
not to cure conditions that exceed the Maximum Remediation Amount, and Seller
having used commercially reasonable efforts is unable to cure all conditions
prior to the Closing, then (A) Seller shall remain obligated to cure as promptly
as reasonably practicable after the Closing all such remaining conditions, and
(B) Buyer may seek indemnification with respect to any breach of this
post-Closing obligation and such claim for indemnification may be brought
without the requirement that such claims meet or exceed the Threshold Amount.

            6.25.2. In the event this Agreement is terminated or fails to close
in accordance with its terms, Buyer agrees to repair any damage or disturbance
it causes to the Real Property in the course of such investigative activities by
returning such Real Property to approximately the same condition as existed
prior to such investigative activities. Buyer will indemnify, defend and hold
Seller free and harmless from and


                                       34
<PAGE>

against any and all Losses of any type arising directly out of any act or
omission of Buyer or any of Buyer's representatives on or about the Real
Property in the course of such investigative activities.

            6.25.3. All information collected and generated as a result of the
environmental due diligence authorized by Section 6.25.1 will be subject to the
terms and conditions of Section 6.21 of this Agreement. Buyer will provide to
Seller copies of all reports, assessments and other information composed or
compiled by Buyer's environmental consultants within five Business Days after
Buyer's receipt of copies thereof.

      6.26. Marketing Efforts. Seller will continue to market digital video
services and the cable modem services provided through @Home in the ordinary
course of business consistent with past practices.

      6.27. Expired Leases. Seller will exercise commercially reasonable efforts
prior to the Closing to obtain written renewals or extensions for at least one
year following the Closing of all leases of Real Property that will have expired
prior to the Closing.

      6.28. System Telephone Services. Prior to the Closing, Buyer will select a
vendor for the provision, and arrange for the transition, of all telephony
services (e.g., long distance, data circuits, and 800 number) used in connection
with the operation of the Systems. If Buyer fails to effect the transition of
telephony services to its selected vendor as of the Closing Date, then Buyer
will reimburse Seller for all direct charges incurred by Seller after the
Closing with respect to telephony services used in connection with the operation
of the Systems or in the conduct of the Business.

9. TERMINATION.

      9.1. Events of Termination. This Agreement may be terminated and the
transactions contemplated by this Agreement may be abandoned at any time prior
to the Closing:

            9.1.1. by the mutual written consent of Buyer and Seller;

            9.1.2. by either party, upon written notice to the other party, if
the transactions contemplated by this Agreement to take place at the Closing
have not been consummated by the date which is 12 months after the date of this
Agreement, for any reason other than (a) a breach or default by such party in
the performance of any of its obligations under this Agreement, or (b) the
failure of any representation or warranty of such party to be accurate;


                                       40
<PAGE>

            9.1.3. by either party at any time upon written notice to the other,
if the other is in material breach or default of any of its covenants,
agreements or other obligations in this Agreement or in any Transaction Document
and fails to cure such breach or default (a) within the 30-day period following
such written notice or, (b) if such breach or default is incapable of being
cured within such 30-day period and the defaulting party does not promptly
initiate and diligently pursue such cure to completion upon receipt of such
notice, within a reasonable period of time; or

            9.1.4. by either party, immediately upon written notice to the
other, if all of the conditions to the Closing have been satisfied or waived and
the other party refuses or is unable to consummate the transactions contemplated
by this Agreement for any reason within the time period determined pursuant to
Section 8.1.1.

            9.1.5. by either party as otherwise provided in this Agreement.

      9.2. Effect of Termination. If this Agreement is terminated pursuant to
Section 9.1, all obligations of the parties under this Agreement will terminate
except for the obligations set forth in this Section and in Sections 6.21 and
11.16. Notwithstanding a party's right to pursue remedies for breach of contract
upon termination of this Agreement in accordance with Section 9.1, no remedies
for breaches of representations and warranties will be available if this
Agreement is terminated pursuant to Section 9.1, and no party will be liable for
any incidental, consequential, exemplary, special, or punitive damages in
connection with any claim for breach of this Agreement. Notwithstanding the
foregoing, if this Agreement is terminated by Seller pursuant to Sections 9.1.3
or 9.1.4, then Seller will be entitled to receive, as liquidated damages and in
lieu of any other damages for breach of contract, the amount of $50,000,000. The
parties acknowledge that it is impractical and would be extremely difficult to
determine the actual damages that may proximately result from Buyer's failure to
perform its obligations under this Agreement. Accordingly, the liquidated
damages provided in this Section 9.2 are (a) not a penalty, and (b) reasonable
and not disproportionate to the presumed damages to Seller from a failure by
Buyer to comply with its obligations under this Agreement.

10. SURVIVAL OF REPRESENTATIONS AND WARRANTIES; INDEMNIFICATION.

      10.1. Survival of Representations and Warranties. The representations,
warranties, covenants and agreements of Seller in this Agreement and the
Transaction Documents (other than covenants and agreements which by their terms
are to be performed after the Closing Date) will survive until 12 months after
the Closing Date, except that the representations, warranties and covenants with
respect to Taxes, title and environmental matters, and third party claims
relating to Excluded Assets or Excluded Liabilities, will survive until 30 days
after the expiration of the relevant statute of limitations. The
representations, warranties, covenants and agreements (other than the covenants
and agreements which by their terms are to be performed after the Closing Date)
of Buyer in this Agreement and the Transaction Documents will survive until 12
months after the Closing Date. The covenants and agreements of the parties in
this Agreement and in the Transaction Documents to be delivered by Seller or
Buyer


                                       41
<PAGE>

pursuant to this Agreement, that are by their terms intended to be performed
after the Closing will survive the Closing and will continue in full force and
effect in accordance with their terms. The applicable periods of survival of the
representations, warranties, covenants and agreements prescribed by this Section
10.1 are referred to as the "Survival Period." The liabilities of the parties
under their respective representations, warranties, covenants and agreements
will expire as of the expiration of the applicable Survival Period; provided,
however, that such expiration will not include, extend or apply to any breach of
which has been asserted by a party in a written notice to the breaching party
before such expiration or about which the breaching party has given the other
party written notice before such expiration indicating that facts or conditions
exist that, with the passage of time or otherwise, can reasonably be expected to
result in a breach (and describing such potential breach in reasonable detail).

      10.2. Indemnification by Seller. Following the Closing, Seller will
indemnify, defend and hold harmless Buyer and its shareholders and its and their
respective Affiliates, and the shareholders, directors, officers, employees,
agents, successors and assigns of any of such Persons, from and against all
Losses of or to Buyer or any such other indemnified Person resulting from or
arising out of (a) any breach of any representation or warranty made by Seller
in this Agreement, (b) any breach of any covenant, agreement or obligation of
Seller contained in this Agreement, (c) any liability or obligation of Seller or
relating to the Business not included in the Assumed Obligations and
Liabilities, and (d) any labor or employment matter relating to the System
Employees that is attributable to any act or omission of Seller occurring prior
to the Closing.

      10.3. Indemnification by Buyer. Following the Closing, Buyer will
indemnify, defend and hold harmless Seller and Seller's shareholders, directors,
officers, employees, agents, successors and assigns, from and against all Losses
of or to Seller or any such other indemnified Person resulting from or arising
out of (a) any breach of any representation or warranty made by Buyer in this
Agreement, (b) any breach of any covenant, agreement or obligation of Buyer
contained in this Agreement, (c) the failure by Buyer to perform the Assumed
Obligations and Liabilities, (d) any claim made by a System Employee relating to
Buyer's use of such Employee's personnel files obtained from Seller at the
request of Buyer, and (e) Buyer's waiver of its condition to Closing set forth
in Section 7.2.4 and the resulting transfer of the Assets without having
obtained the necessary Required Consents.

      10.4. Third Party Claims. Promptly after the receipt by any party of
notice of any claim, action, suit or proceeding by any Person who is not a party
to this Agreement (collectively, an "Action"), which Action is subject to
indemnification under this Agreement, such party (the "Indemnified Party") will
give reasonable written notice to the party from whom indemnification is claimed
(the "Indemnifying Party"). The Indemnified Party will be entitled, at the sole
expense and liability of the Indemnifying Party, to exercise full control of the
defense, compromise or settlement of any such Action unless the Indemnifying
Party, within a reasonable time after the giving of such notice by the
Indemnified Party, (a) admits in writing to the Indemnified Party the
Indemnifying Party's liability to the Indemnified Party for such Action under
the terms


                                       42
<PAGE>

of this Section 10, (b) notifies the Indemnified Party in writing of the
Indemnifying Party's intention to assume such defense, (c) provides evidence
reasonably satisfactory to the Indemnified Party of the Indemnifying Party's
ability to pay the amount, if any, for which the Indemnified Party may be liable
as a result of such Action and (d) retains legal counsel reasonably satisfactory
to the Indemnified Party to conduct the defense of such Action. The other party
will cooperate with the party assuming the defense, compromise or settlement of
any such Action in accordance with this Agreement in any manner that such party
reasonably may request. If the Indemnifying Party so assumes the defense of any
such Action, the Indemnified Party will have the right to employ separate
counsel and to participate in (but not control) the defense, compromise or
settlement of the Action, but the fees and expenses of such counsel will be at
the expense of the Indemnified Party unless (i) the Indemnifying Party has
agreed to pay such fees and expenses, (ii) any relief other than the payment of
money damages is sought against the Indemnified Party or (iii) the Indemnified
Party will have been advised by its counsel that there may be one or more
defenses available to it which are different from or additional to those
available to the Indemnifying Party, and in any such case that portion of the
fees and expenses of such separate counsel that are reasonably related to
matters covered by the indemnity provided in this Section 10 will be paid by the
Indemnifying Party. No Indemnified Party will settle or compromise any such
Action for which it is entitled to indemnification under this Agreement without
the prior written consent of the Indemnifying Party, unless the Indemnifying
Party has failed, after reasonable notice, to undertake control of such Action
in the manner provided in this Section 10.4. No Indemnifying Party will settle
or compromise any such Action (i) in which any relief other than the payment of
money damages is sought against any Indemnified Party or (ii) in the case of any
Action relating to the Indemnified Party's liability for any Tax, if the effect
of such settlement would be an increase in the liability of the Indemnified
Party for the payment of any Tax for any period beginning after the Closing
Date, unless the Indemnified Party consents in writing to such compromise or
settlement.

      10.5. Limitations on Indemnification - Seller. Seller will not be liable
for indemnification arising under Section 10.2 (except for indemnification
claims made pursuant to subsection (d) of Section 10.2) for any Losses of or to
Buyer or any other person entitled to indemnification from Seller unless the
amount of such Losses for which Seller would, but for the provisions of this
Section 10.5, be liable exceeds, on an aggregate basis, $5,000,000 (the
"Threshold Amount"), provided that in determining whether the Threshold Amount
has been exceeded, there shall not be included any Losses arising from any
single claim that is less than $10,000 in the aggregate. If the Threshold Amount
is exceeded, Seller will be liable for the full amount of all Losses (including
any claims for Losses of less than $10,000), which amount will be due and
payable within 15 days after the later of (a) the date Seller receives a
statement therefor and (b) the date an Action with respect to such Losses is
settled or decided in accordance with Section 10.4. Seller will not be liable
for Buyer's incidental, consequential, exemplary, special, or punitive damages.
The maximum aggregate amount that Seller will be required to pay for
indemnification arising under Section 10.2 in respect of all claims by all
indemnified parties is $75,000,000. Notwithstanding the preceding, neither the
Threshold Amount nor the maximum limits specified in this


                                       43
<PAGE>

Section 10.5 will apply to the obligation to pay post-Closing adjustments
pursuant to Section 3.3, Seller's obligation to discharge the Excluded
Liabilities, or to Seller's breach of its representations and warranties that it
has title to the Assets (including Real Property), and the Threshold Amount will
not apply as otherwise provided in this Agreement.

      10.6. Limitations on Indemnification - Buyer. Buyer will not be liable for
indemnification arising under Section 10.3 for any Losses of or to Seller or any
other person entitled to indemnification from Buyer unless the amount of such
Losses for which Buyer would, but for the provisions of this Section 10.6, be
liable exceeds, on an aggregate basis, the Threshold Amount, provided that in
determining whether the Threshold Amount has been exceeded, there shall not be
included any Losses arising from any single claim that is less than $10,000 in
the aggregate. If the Threshold Amount is exceeded, Seller will be liable for
the full amount of all Losses (including any claims for Losses of less than
$10,000), which amount will be due and payable within 15 days after the later of
(a) the date Buyer receives a statement therefor and (b) the date an Action with
respect to such Losses is settled or decided in accordance with section 10.4.
Buyer will not be liable for Seller's incidental, consequential, exemplary,
special, or punitive damages. The maximum aggregate amount that Buyer will be
required to pay for indemnification arising under Section 10.3 in respect of all
claims by all indemnified parties is $75,000,000. Notwithstanding the preceding,
neither the Threshold Amount nor the maximum limits specified in this Section
10.6 will apply to the obligation to pay the Purchase Price, as adjusted, and
post-Closing adjustments pursuant to Section 3.3, or to Buyer's obligation to
assume and perform the Assumed Obligations and Liabilities, and the Threshold
Amount will not apply as otherwise provided in this Agreement.

      10.7. Sole Remedy. Each party acknowledges and agrees that, should the
Closing occur, its sole and exclusive remedy against the other with respect to
any breach of representation, warranty, covenant, agreement or obligation will
be pursuant to the indemnification provisions set forth in this Section 10.

11. MISCELLANEOUS.

      11.1. Parties Obligated and Benefited. Subject to the limitations set
forth below, this Agreement will be binding upon the parties and their
respective permitted assigns and successors in interest and will inure solely to
the benefit of the parties and their respective permitted assigns and successors
in interest, and no other Person will be entitled to any of the benefits
conferred by this Agreement. Without the prior written consent of the other
party, no party will assign any of its rights under this Agreement or delegate
any of its duties under this Agreement; provided, however, that (i) Seller may
assign its rights under this Agreement (but not obligations) to a qualified
intermediary within the meaning of Code Section 1.1031(k)-1(g)(4)(iii)
("Qualified Intermediary") and (ii) either party may assign its rights to an
Affiliate so long as the assigning party continues to be bound by the terms of
this Agreement. If Seller elects to assign its rights under this Agreement to a
Qualified Intermediary, Buyer will cooperate with Seller as may be reasonably
necessary in connection with such assignment and the


                                       44
<PAGE>

deferred tax-free exchange to be accomplished in connection therewith, including
acknowledging the execution of a written agreement between Seller and the
Qualified Intermediary.

required or permitted to be given under this Agreement will be in writing and

      11.3. Attorneys' Fees. In the event of any action or suit based upon or
arising out of this Agreement, the prevailing party will be entitled to recover
reasonable attorneys' fees and other costs of such action or suit from the other
party.

      11.4. Right to Specific Performance. Each party acknowledges that the
unique nature of the transactions contemplated by this Agreement and the
circumstances under which this Agreement has been entered into renders money
damages for a breach of the parties' respective obligations to consummate the
transactions contemplated by this Agreement an inadequate remedy, and the
parties agree that either party will be entitled to pursue specific performance
as a remedy for such breach without the requirement of posting a bond or other
security therefor; provided, however, that Seller will have such right to
specific performance only in connection with a breach of Buyer's confidentiality
obligations under Section 6.21 hereof.

      11.5. Waiver. This Agreement or any of its provisions may not be waived
except in writing. The failure of any party to enforce any right arising under
this Agreement on one or more occasions will not operate as a waiver of that or
any other right on that or any other occasion.

      11.6. Captions. The captions of this Agreement are for convenience only
and do not constitute a part of this Agreement.

      11.7. Choice of Law. THIS AGREEMENT AND THE RIGHTS OF THE PARTIES UNDER IT
WILL BE GOVERNED BY AND CONSTRUED IN ALL RESPECTS IN ACCORDANCE WITH THE LAWS OF
THE STATE OF DELAWARE, WITHOUT REGARD TO THE CONFLICTS OF LAWS RULES OF
DELAWARE.

      11.8. Terms. Terms used with initial capital letters will have the
meanings specified, applicable to both singular and plural forms, for all
purposes of this Agreement. The word "include" and derivatives of that word are
used in this Agreement in an illustrative sense rather than limiting sense.

      11.9. Further Actions. Seller and Buyer will execute and deliver to the
other, from time to time at or after the Closing, for no additional
consideration and at no additional cost to the requesting party, such further
assignments, certificates, instruments, records, or other documents, assurances
or things as may be reasonably necessary to give full effect to this Agreement
and to allow each party fully to enjoy and exercise the rights accorded and
acquired by it under this Agreement.

      11.10. Time. Time is of the essence under this Agreement. If the last day
permitted for giving of any notice or the performance of any act required or
permitted under this Agreement falls on a day which is not a Business Day, the
time for the giving of such notice or the performance of such act will be
extended to the next succeeding Business Day.

      11.11. Late Payments. If either party fails to pay the other any amounts
when due under this Agreement, the amounts due will bear interest from the due
date to the date of payment at the annual rate publicly announced from time to
time by The Bank


                                       46

of New York as its prime rate (the "Prime Rate") plus 3%, adjusted as and when
changes in the Prime Rate are made.

      11.12. Counterparts. This Agreement may be executed in counterparts, each
of which will be deemed an original. This Agreement will become binding when one
or more counterparts, individually or taken together, bear the signatures of all
parties to this Agreement. Delivery of an executed signature page of this
Agreement by facsimile transmission will constitute effective and binding
execution and delivery of this Agreement.

      11.13. Entire Agreement. This Agreement (including the Schedules and
Exhibits referred to in this Agreement, which are incorporated in and constitute
a part of this Agreement) and the Transaction Documents contain the entire
agreement of the parties and supersede all prior oral or written agreements and
understandings with respect to the subject matter hereof other than any letter
or agreement between the Buyer and Seller that specifically refers to this
Section 11.13. This Agreement may not be amended or modified except by a writing
signed by the parties.

      11.14. Severability. Any term or provision of this Agreement which is
invalid or unenforceable will be ineffective to the extent of such invalidity or
unenforceability without rendering invalid or unenforceable the remaining rights
of the Person intended to be benefited by such provision or any other provisions
of this Agreement.

      11.15. Construction. This Agreement has been negotiated by Buyer and
Seller and their respective legal counsel, and legal or equitable principles
that might require the construction of this Agreement or any provision of this
Agreement against the party drafting this Agreement will not apply in any
construction or interpretation of this Agreement.

      11.16. Expenses. Except as otherwise expressly provided in this Agreement,
each party will pay all of its expenses, including attorneys' and accountants'
fees, in connection with the negotiation of this Agreement, the performance of
its obligations and the consummation of the transactions contemplated by this
Agreement.

      11.17. Commercially Reasonable Efforts. For purposes of this Agreement,
unless a different standard is expressly provided with respect to any particular
matter, any requirement herein that a party use "commercially reasonable
efforts" will not be deemed to require that party to undertake extraordinary
measures, including the initiation or prosecution of legal proceedings or the
payment of amounts in excess of normal and usual filing fees and processing
fees, if any.

                            FORM OF BILL OF SALE AND

Mediacom Communications Corporation
100 Crystal Run Road
Middletown, New York 10941

Gentlemen:

      Reference is made to that certain Asset Purchase Agreement dated as of
February 26, 2001 (the "Agreement"), among the undersigned Affiliates ("Seller")
of AT&T Broadband, LLC ("AT&T Broadband") and Mediacom Communications
Corporation ("Buyer"). This letter is being delivered to you pursuant to Section
8.2(m) of the Agreement. Capitalized terms used herein, unless otherwise defined
herein, shall have the meanings ascribed to them in the Agreement.

      In order to effectuate the purposes and intent of the Agreement, each
Seller and AT&T Broadband hereby covenants and agrees that for a period
commencing on the date hereof and expiring on the third anniversary from the
date hereof, that it shall not be involved, directly or indirectly, either
personally, or as an owner, employee, partner, associate, officer, manager,
agent, advisor, consultant or otherwise, with any business which is competitive
with the business of Buyer within the Service Area. A business shall be deemed
competitive with the business of Buyer if it involves the development,
construction, sale, lease, rental or operation of any cable television system,
satellite master antenna television system, multi-point distribution system or
"open video" system, as such terms are generally defined and used in the
communications industry, and provides video, telephony or data services over
such system; provided, however, that nothing herein shall restrict Seller or
AT&T Broadband from being a passive investor or shareholder holding less than
five percent of the outstanding voting stock or equity interest in any such
competitive business, and provided, further, that nothing
<PAGE>

herein shall restrict [Excite@Home] from being involved or engaging in any
business within the Service Area.

      If the terms or provisions of this Noncompetition Agreement are breached
or threatened to be breached, each of Seller and AT&T Broadband expressly
consents that, in addition to any other remedy Buyer may have, Buyer may apply
to any court of competent jurisdiction for injunctive relief in order to prevent
the continuation of any existing breach or the occurrence of any threatened
breach.

      If any provision of this Noncompetition Agreement is determined to be
unreasonable or unenforceable, such provision and the remainder of this
Noncompetition Agreement shall not be declared invalid, but rather shall be
modified and enforced to the maximum extent permitted by law.

      This letter is intended to form a part of the Agreement and, accordingly,
reference is hereby made to Section 11.13 of the Agreement.

                                        Sincerely,

                                        [SIGNATURE BLOCKS]

                                     to the
                            Asset Purchase Agreement
                                      among
                       MEDIACOM COMMUNICATIONS CORPORATION
                                       and
                           THE AT&T BROADBAND PARTIES

                               RETAINED FRANCHISES

For purposes of this Agreement, a "Retained Franchise" means any Franchise for
which by the Closing Date: (a) the Required Consent to transfer such Franchise
to Buyer either was not obtained, has not been granted by operation of law, or
the applicable Governmental Authority or its designee has taken public action to
the effect, or has given written notice to Buyer or Seller of its, or its
designee's assertion, that the Required Consent has not been granted by
operation of law, or (b) a Governmental Authority has the right directly or
indirectly to acquire all or any portion of a System, which right has not
expired by its terms or expressly been waived or abandoned. The Retained
Franchise includes not only the applicable Franchise, but also all of the Assets
that are: (i) located in the Service Area of the Retained Franchise; and (ii)
used solely for the operation of the portion of the System in the portion of the
Service Area of the Retained Franchise.
