         2 Service Components.

                  2.1 Indefeasible Right to Use. AT&T hereby grants to @Home for
the Term of this Agreement an IRU in the Capacity, as the Capacity may be
increased from time to time pursuant to the terms hereof.

                  2.2 Collocation and Interconnection. AT&T shall provide @Home
with collocation space along the @Home Backbone Network in (i) the AT&T POPs
under an agreement substantially in the form attached as Exhibit F (Collocation
Agreement). In each AT&T POP, AT&T shall provide @Home with three rack spaces
(as used in this Agreement, "rack space" shall have the meaning set forth in
Exhibit F) and associated collocation and interconnection services, as listed in
Exhibit F, or as hereafter mutually agreed upon. AT&T shall use its best efforts
to make the three rack spaces contiguous. AT&T shall procure on behalf of @Home
one rack space in the Third-Party POPs. As part of the Services provided
hereunder, AT&T will extend its facilities at no cost to @Home to the @Home
designated demarcation point within the Third-Party POPs.

         3 Performance Phase.

                  3.1 Phase One - Interim Services. To assist @Home's transition
to the AT&T Network, during the period from January 1, 1999 through Acceptance
of the Phase Two Services on the applicable Route, AT&T will provide @Home
either with the Phase Two Service Components or with alternate capacity using
Asynchronous Transfer Mode technology ("ATM"), or with a hybrid arrangement
including some portion of the Phase Two Routes combined with ATM. @Home has an
existing ATM service arrangement with Sprint, which arrangement 



<PAGE>   4
                                                                          Page 4


currently is being restructured. @Home will arrange for AT&T to assume @Home's
rights and obligations under the Sprint ATM service arrangement, once it is
restructured (the "Sprint ATM Arrangement") provided that @Home shall remain
liable for, and AT&T shall assume no liability for, termination charges,
shortfall charges, charges for service provided prior to January 1, 1999, and
other charges not directly related to the provision of ATM service under the
Sprint ATM Arrangement from January 1, 1999 forward. AT&T's willingness to
assume the Sprint ATM Arrangement is contingent upon its review and assessment
of the terms. In the event that AT&T incurs charges under the Sprint ATM
Arrangement in excess of five million dollars, @Home will pay the amount of such
excess to AT&T as an Assumption Fee, except if AT&T does not deliver the Phase
Two Capacity by the Phase Two Commitment Date the charges incurred under the
Sprint ATM Arrangement from April 1, 1999 through the date on which AT&T
delivers the Phase Two Capacity will not be counted in calculating any
Assumption Fee. The parties acknowledge and agree that (i) the assumption of the
Sprint ATM Arrangement by AT&T is an accommodation to @Home to induce it to
enter into this Agreement and (ii) @Home has informed AT&T that it would not
enter into this Agreement without this provision.

                  3.2 Phase Two - OC-48 and OC-3 Capacity. AT&T shall provide, 
at no additional cost to @Home, capacity (the "Phase Two Capacity") along
certain Routes (collectively, the "Phase Two Routes") as follows: OC-3 capacity
on the Routes and in the amounts listed on Exhibit C and in OC-48 capacity on
the Routes listed on Exhibit C. The "Phase Two Service Components" shall include
the Phase Two Capacity and corresponding collocation and interconnection
services as set forth in the Section entitled Collocation and Interconnection
and Exhibit F. AT&T shall deliver the Phase Two Service Components so that they
are Accepted no later than March 31, 1999 (the "Phase Two Commitment Date"). The
Phase Two Service Components shall be subject to the testing and acceptance
process set forth in the Section entitled Testing and Acceptance. The Phase Two
Service Components shall terminate upon Acceptance of the Phase Three Service
Components (defined below).

                  3.3 Phase Three - OC-48 Capacity. AT&T shall provide at no
additional cost to @Home 2 OC-48's (including the Four-Port Network Electronics)
(the "Phase Three Capacity") on the Routes listed on Exhibit D (the "Phase Three
Routes") in accordance with the terms of this Agreement including Exhibit B
(Technical Specifications). The "Phase Three Service Components" shall include
the Phase Three Capacity and corresponding collocation and interconnection
services as set forth in the Section entitled Collocation and Interconnection
and Exhibit F. AT&T shall provide the Phase Three Service Components so that
they are Accepted no later than the relevant scheduled delivery dates specified
on Exhibit D (the "Phase Three Delivery Dates").

                  3.4 Other Capacity. The parties agree to work together in good
faith to enter into a separate agreement or a contract tariff by January 31,
1999 to cover @Home's additional OC-3 (or larger) needs. In addition, @Home, at
its option, may order, and AT&T shall use commercially reasonable efforts to
promptly provide, capacity on routes not available through the AT&T Network
("Off-net Capacity"). AT&T shall provide such Off-net Capacity at 115% of the
cost (net of discount) such is actually obtained by AT&T from a non-affiliated
third-party carrier, subject to such other terms and conditions as apply between
AT&T and such other carrier.

         4. Delivery and Liquidated Damages



<PAGE>   5
                                                                          Page 5


                  4.1 Delivery. AT&T shall complete the construction,
installation and testing of the Phase Two Service Components and the Phase Three
Service Components so that they are Accepted in accordance with the terms of
this Agreement and specifically Exhibit B (Technical Specifications) by the
Phase Two Commitment Date and each of the applicable Phase Three Delivery Dates,
respectively. Notwithstanding the foregoing, each party understands that a risk
of delay is inherent in the provisioning of Phase Three Service Components due
to the extent of the project. Therefore, there shall be a completion grace
period extending from each of the Phase Three Delivery Dates as indicated on
Exhibit D until August 31, 1999 (the "Phase Three Commitment Date") for AT&T to
complete the construction, installation and testing of the Phase Three Service
Components. There shall be no grace period associated with the Phase Two
Commitment Date. The Phase Two Commitment Date and the Phase Three Commitment
Date are hereinafter collectively referred to as the "Commitment Dates."

                  4.2 Liquidated Damages. The parties agree that it would be
difficult to determine the precise amount of damages which @Home would suffer in
the event that the @Home Backbone Network or any portion thereof is not
completed by the applicable Commitment Date. Therefore, the parties agree, as
their best estimate of such damages to @Home that in the event that any of the
Service Components are not delivered and Accepted for any Significant Route by
the applicable Commitment Date, @Home shall receive a discount against the
purchase price (the "Discount") in the amount of $10,000 per month (prorated for
partial months) per City Pair for such Significant Route. The Discount shall
continue to accrue until the Service Components for such Significant Route are
delivered to and Accepted by @Home.

                  4.3 Cover Service Components. In the event the Service
Components for any Route have not been Accepted 120 days after the applicable
Commitment Date, @Home may, at its option, obtain equivalent capacity for the
Route from another carrier and AT&T shall reimburse @Home for all expenses
charged by such other carrier until such time that the Service Components are
Accepted by @Home for the applicable Route. This cover remedy is in lieu of
liquidated damages under Section 4.2 for such late delivery for the time such
alternative capacity is provided.

                  4.4 Alternate Service Components. If @Home has not Accepted
the Phase Three Service on any Route by the Phase Three Commitment Date, AT&T
shall provide @Home with two OC-48s between the [City Pairs] for each applicable
Route not yet Accepted (the "Alternate Capacity"). The Alternate Service
Components shall include the Alternate Capacity and corresponding collocation
and interconnection services as set forth in the Section entitled Collocation
and Interconnection and Exhibit F. If necessary, AT&T will provide the Alternate
Service Components with services it obtains from another carrier. AT&T shall
provide the Alternate Service Components to @Home at no additional cost to
@Home. To the extent that AT&T provides Alternate Service Components, @Home will
not have the right to obtain Cover Service Components as set forth in Section
4.3, and will not have the right to liquidated damages under Section 4.2 for
such late delivery for the time the Alternative Service Components are provided.

                  4.5 Substantial Failure to Deliver Routes. If by March 31,
2000, regardless of any Force Majeure Events, 70% of all the Phase Three Routes
and associated Service Components have not been Accepted by @Home, then @Home
shall have the right to 

<PAGE>   6
                                                                          Page 6


terminate this Agreement by providing written notice thereof to AT&T. In such
event, AT&T shall refund to @Home any amounts actually paid by @Home to AT&T
pursuant to the Section entitled Payment, except that AT&T may withhold an
amount for each Accepted Route, the "Usage Fee." The Usage Fee shall equal the
portion of the IRU Fee paid through the date of termination of this Agreement
with respect to such Route (calculated on a pro-rata basis based on mileage)
multiplied by a fraction. The fraction shall have a numerator equal to the
number of months @Home was provided Service on such Route and a denominator of
240. In addition, regardless of any Force Majeure Events, @Home may terminate
this Agreement with respect to any Route for which the Service Components have
not been Accepted within two years of the Effective Date.

         5. Payment.

                  5.1 IRU Fee. In consideration for the Interim Service and the
IRUs granted hereunder in the Capacity, @Home shall pay AT&T ninety million 
dollars ($90,000,000) (the "IRU Fee") payable in accordance with the schedule 
set forth in Exhibit I (Payment Terms).

                  5.2 Maintenance. In consideration for the provision of
maintenance services provided by or arranged for by AT&T with respect to Phase
Three Capacity in accordance with the Section entitled Operation, Maintenance
and Repair, @Home shall pay AT&T a quarterly Maintenance Fee (as defined below)
in arrears on a Route mileage basis (regardless of the amount of capacity used
on the Route). The mileage used to calculate the Maintenance Fee for each
quarter shall be calculated by adding together the number of applicable Route
miles in use at the beginning and end of the quarter and dividing by two. The
"Maintenance Fee" shall be the sum of two components: the "Services Component"
and the "Repair/Replacement Component". The Services Component shall be equal to
$6.00 per quarter per Route mile. The Repair/Replacement Component shall be
lower during the period the initial equipment used to provide the Capacity is
new to reflect AT&T's ability to take advantage of manufacturers' warranties.
The Repair/Replacement Component shall be (a) $2.00 per quarter per Route mile
during the first three years of Phase Three Capacity on the relevant Route and
(b) $6.30 per quarter per Route mile thereafter.

                            5.2.1 CPI Increase. The Maintenance Fee shall be
adjusted annually by the aggregate change in the Consumer Price Index, as set
forth below. Beginning at the start of the first year for which the Maintenance
Fee applies, and each additional year thereafter, the Maintenance Fee payable
hereunder shall be determined by multiplying the monthly Maintenance Fee set
forth in Section 5.2 by a fraction, the numerator of which shall be (i) the
average of the monthly Consumer Price Indices for the 12 months immediately
preceding the date on which the Maintenance Fee is to be adjusted and (ii) the
denominator of which shall be the average of the monthly Consumer Price Indices
for the 12 months immediately preceding the Effective Date of this Agreement.

                  5.3 Collocation. In consideration for collocation at the AT&T
POPs @Home shall pay AT&T the amounts set forth in Exhibit F. AT&T shall charge
@Home for rack spaces in Third-Party POPs only the actual cost therefor to AT&T,
without mark-up.

                            5.3.1 CPI Increase. The collocation charges shall be
adjusted annually by the aggregate change in the Consumer Price Index, as set
forth below. At the beginning of each calendar year beginning with 2000, the
collocation charges shall be 

<PAGE>   7
                                                                          Page 7


determined by multiplying such charges by a fraction, the numerator of which
shall be (a) the average of the monthly Consumer Price Indices for the 12 months
preceding the date on which the charge is to be adjusted and (b) the denominator
of which shall be the average of the monthly Consumer Price Indices for the 12
months immediately preceding the date on which the charges were first
established under this Agreement.

                  5.4 Invoicing and Payment Terms. AT&T shall send a bill to
@Home for all charges payable under this Agreement. With the exception of the
IRU Fee which each shall be due on the dates set forth in Exhibit I, @Home shall
pay all invoiced amounts within 30 days after the date of an invoice therefor.
@Home's obligation to pay a charge that is subject to a specifically identified
good faith dispute will be suspended while the disputed charge is under
investigation by AT&T if (a) @Home provides a written explanation of the basis
for such dispute prior to the date such payment is due or (b) an AT&T account
inquiry and collections representative provides express written consent to
suspend the payment obligation pending investigation. If any amount due under
this Agreement not so disputed is not received within fifteen days after the
date due, then, in addition to its other remedies available under this
Agreement, AT&T may in its sole discretion impose a late payment charge
calculated each month at the rate of 1% per month (or 12% per annum), such late
charge being payable upon demand by AT&T.

         6. Upgrades and Expansion.

                  6.1 Upgrade of @Home Backbone Network at @Home's Request. At
any time after August 31, 1999 and during the Term of this Agreement, @Home
shall have the right to upgrade its Capacity on @Home Routes (a "Requested
Upgrade"). In connection with a Requested Upgrade, @Home shall have the right to
purchase from AT&T additional network electronics and/or circuit electronics, in
order to increase the Capacity on the applicable @Home Route to the Market
Equivalent Capacity. @Home may request such upgrade by providing written notice
(the "Upgrade Request Notice") to such effect to AT&T. The Upgrade Request
Notice shall include the Route(s) and the amount of additional capacity for each
Route (provided however the effective Capacity that @Home obtains shall not
exceed the Market Equivalent Capacity for such Route, except if @Home has
previously made an Existing Route Expansion (as defined below) for the Route
that @Home desires, in which case the effective capacity which @Home obtains
shall not exceed the product of (a) the Market Equivalent Capacity for the Route
and (b) the Excess Expansion Percentage (as defined below) for the Route). At
such time, AT&T shall be obligated to provide @Home with (i) the Requested
Upgrade or (ii) alternative capacity along the Routes and in the amount
requested by @Home as part of the Requested Upgrade ("Additional Capacity
Without Upgrade");. Within 60 days of the date of the Upgrade Request Notice,
AT&T shall respond in writing (the "Upgrade Response Notice") indicating whether
it has selected option (i) or option (ii) above and providing a detailed
description of the upgraded transmission system or the capacity, as applicable,
the anticipated time line for installation, completion and delivery, as
applicable and the estimated cost of the upgrade or capacity. Such cost shall be
calculated in accordance with the Section entitled Upgrade Cost. Within 30 days
after receipt of the Upgrade Response Notice, @Home shall provide AT&T with
written confirmation of @Home's desire (or lack thereof) to proceed with the

                  6.2 Expansion of @Home Backbone Network. At any time after
August 31, 1999 and during the Term of this Agreement, @Home shall have the
right to request an expansion of the @Home Backbone Network to (a) include
Routes not then on the @Home Backbone Network (a "Route Expansion") or (b)
include additional capacity above the Market Equivalent Capacity on an @Home
Route then in use (an "Existing Route Expansion"), (in either case, a "Requested
Expansion"). In connection with a Requested Expansion, @Home shall have the
right to purchase from AT&T additional network electronics and/or circuit
electronics, in order to obtain Capacity (a) in a Route Expansion, on such
Routes up to the Market Equivalent Capacity or (b) in an Existing Route
Expansion, up to an amount of capacity above the Market Equivalent Capacity as
specified by @Home (the percentage amount requested in an Existing Route
Expansion above the Market Equivalent Capacity is referred to as the "Excess
Expansion Percentage") @Home may request such expansion by providing written
notice (the "Expansion Request Notice") to such effect to AT&T. The Expansion
Notice shall include the new Route(s) and the amount of additional capacity for
each new Route that @Home desires. At such time, AT&T shall provide @Home with
(i) the Requested Expansion using such upgraded facilities; or (ii) alternative
capacity in the amount requested by @Home as part of the Requested Expansion
("Additional Expansion Capacity Without Upgrade"); provided however that in
either case, the Capacity that @Home obtains shall not exceed (a) in the case of
a Route Expansion, the Market Equivalent Capacity or (b) in the case of an
Existing Route Expansion, the product of (1) the Market Equivalent Capacity
multiplied by (2) the sum of one plus the Excess Expansion Percentage. Within 60
days of the date of the Expansion Request Notice, AT&T shall respond in writing
(the "Expansion Response Notice") indicating whether it has selected option (i)
or option (ii) above and providing a detailed description of the upgraded
transmission system or the capacity, as applicable, the anticipated time line
for installation, completion and delivery, as applicable and the estimated cost
of the upgrade or capacity. Such cost shall be calculated in accordance with the
Section entitled Additional Capacity Cost. Within 30 days after receipt of the
Expansion Response Notice, @Home shall provide AT&T with written confirmation of
@Home's desire (or lack thereof) to proceed with the Requested Expansion. @Home
shall pay for the Requested Expansion in accordance with the Section entitled
Expansion Payment Terms and AT&T shall use commercially reasonable efforts to
provide the additional Capacity promptly.

                  6.3 Upgrade of @Home Backbone Network During AT&T Network
Upgrade. AT&T shall provide written notice (the "Upgrade Notice") to @Home of
each "Upgrade" of the AT&T Network. An "Upgrade" is any change to the AT&T
Network, including but not limited to lighting fiber(s), adding, modifying, or
replacing electronic equipment, that enables AT&T to increase the total number
of channels, or increase the capacity per channel, on a per fiber, per route
basis on all or any part of the AT&T Network. The Upgrade Notice shall include a
detailed description of the upgraded transmission system (including routes,
engineering and capacity), anticipated time line for installation, completion
and delivery and the estimated cost to @Home for @Home's portion of the
Upgrade. Such estimated cost shall be calculated in accordance with the Section
entitled Additional Capacity Cost. @Home may elect to participate in the Upgrade
and to retain AT&T to upgrade the @Home Backbone Network (or such portions of
the @Home Backbone Network as @Home requests) by providing notice (the "Upgrade
Acceptance Notice") to such effect to AT&T in writing within 30 days of
receiving the Upgrade Notice. The Upgrade Acceptance Notice shall include the
Routes and the amounts of capacity for each Route that @Home desires. @Home may
elect to participate in the AT&T Network upgrade on individual Routes, rather
than for the entire Upgrade. @Home may at any time in the future request Service

                                     Page 9


accordance with the Section entitled Upgrade of @ Home Backbone Network at @
Home's Request.

                  6.4 Forecasting and Planning. AT&T and @Home shall meet twice
a year to review @Home's network forecasts, AT&T network planning and status and
to discuss the current Market Equivalent Capacity. In the event the parties do
not agree upon the Market Equivalent Capacity for any Route, at the option of
either party, determination of the Market Equivalent Capacity at such time shall
be referred to the binding decision of a mutually acceptable independent third
party. If the parties do not agree upon such a third party within 30 days of the
exercise of such option, an independent third party will be chosen through
arbitration under the terms of this Agreement.

                  6.5 Transition to New Service. In the event an Upgrade, an
Expansion or a Requested Upgrade requires a transfer of @Home's Service
Components to different electronics, AT&T will effect the transfer in accordance
with mutually acceptable transition procedures approved by the engineering
groups of @Home and AT&T.

                  6.6 Collocation with Upgrade or Expansion. In connection with
a Requested Upgrade, an Upgrade or an Expansion, AT&T shall provide collocation
services to @Home in a manner sufficient to meet @Home's needs. @Home shall pay
the cost for such collocation as set forth in Exhibits F and I.

                  6.7 Acceptance of Upgrade and Expansion. Testing, Acceptance
and payment subsequent thereto of a Requested Upgrade, an Upgrade or an
Expansion shall be in accordance with the section entitled Testing and
Acceptance herein, provided however, that in the event the specifications set
forth in Exhibit B are no longer applicable to the technology employed at the
time of a Requested Upgrade, an Upgrade or an Expansion, the parties shall
mutually agree in writing to specifications in line with industry standards
prior to the testing.

                  6.8 City-Pair Split. At @Home's request, AT&T shall allow
@Home to split any Route between the two cities of a City Pair if AT&T has a
point of presence (the "New POP") in between the two cities. In such case, AT&T
shall provide @Home with collocation (three rack spaces) and interconnection at
the New POP. AT&T's only charge for allowing and implementing such split in the
City Pair will be for the collocation. @Home shall pay the cost for such
collocation as set forth in Exhibits E and I.

         7. Payment for Upgrades and Expansions.

                  7.1 Additional Capacity Cost. Pricing for additional upgrading
to a new higher capacity shall be determined by the following:

                           7.1.1  New Electronic Equipment Pricing Method. The 
payment from @Home for the new network electronics and circuit electronics 
required to obtain capacity beyond the Phase Three Capacity (the "Upgrade 
Cost") shall be determined by AT&T based on @Home's requested upgraded 
configuration of the @Home Backbone Network. The Upgrade Cost shall be equal to 
the product of (a) AT&T's Network and Circuit Electronics Cost (as defined 
below) and (b) a fraction which shall have a numerator equal to the Additional 
Capacity to be derived from such electronics and a denominator which is equal 
to the total capacity which can be derived from such electronics. The "Network 
and Circuit Electronics Cost" shall be equal to AT&T's "actual cost" to provide 
the additional capacity requested, consisting of the actual costs paid by AT&T 
to third parties for all physical elements (active and passive) added to the 
AT&T fibers to prepare and create channel capacity consistent with this 
Agreement and that are used in the deployment of the @Home Backbone Network, 
including

                                                                         Page 10


the costs paid to the equipment vendor for engineering and installation. The 
Network and Circuit Electronics Cost shall be adjusted as follows:

                                    (a)  to not include any cost for 
installation services where such services are otherwise included in the costs 
of the network and circuit electronics invoiced to AT&T and already included 
in the Network and Electronics Cost;

                                    (b)  reduced by the "Discount Percentage." 
The Discount Percentage is the percentage discount, rebate or other direct or 
indirect cost savings ("Discount") that AT&T was given by its supplier of 
network or circuit electronics when AT&T purchased such electronics. If a 
Discount was made available to AT&T in bundled purchases that include network 
electronics or circuit electronics and other equipment not covered under this 
Agreement, the same Discount shall be afforded to @Home for the equipment that 
is installed on the @Home Network;

                                    (c)  decreased to the extent that the 
Comparison Price (as defined below) for such upgrade is less expensive or to 
the extent that a less expensive upgrade could have been possible if AT&T's 
equipment were of a more recent manufacture or design; and

                                    (d)  increased by a mark-up of 20% (that 
is, after the deductions listed above in subsection (a), (b), and (c) are made 
to the Network and Circuit Electronics Cost, the Networks and Circuit 
Electronics Cost shall be multiplied by 1.20).

The "Comparison Price" for an upgrade shall be the lower price, if any, any 
other AT&T-qualified vendor (or, in the event only one vendor is AT&T qualified 
for the type of equipment being considered, any vendor of substantially 
equivalent equipment of comparable quality) could have provided the electronics 
(or substantially equivalent electronics), established as follows: (a) there 
will be semi-annual meetings between @Home and AT&T to review market pricing, 
and based on such meetings, the parties will attempt to mutually establish a 
Comparison Price for any impending upgrade, (b) if no such price can be 
mutually agreed to, the parties will engage a mutually acceptable third-party 
expert to determine the Comparison Price, which determination will be binding 
on the parties, and (c) if no such expert is mutually agreed to, the choice of 
the expert will be determined by an arbitrator under the arbitration provision 
of this Agreement. During such process, AT&T will share equipment market price 
information it has with @Home to the extent allowed by existing non-disclosure 
agreements it has with third parties.

In the event AT&T chooses to supply Additional Capacity Without Upgrade or 
Additional Expansion Capacity Without Upgrade pursuant to option (ii) of the 
section entitled Upgrade of @Home Backbone Network at @Home's Request or of 
option (ii) of the section entitled Expansion of @Home Backbone Network, the 
cost to @Home of such Additional Capacity shall be calculated through a 
reasonable estimate of what the costs would have been as if the facilities 
upgrade set forth above had actually taken place.

<PAGE>   11
                                                                         Page 11

                            7.1.2 Fiber Cost. @Home shall not be required to pay
anything for the right to use fiber on any @Home Route in connection with the
acquisition of Additional Capacity which together with previously existing
capacity on such Route does not exceed the Market Equivalent Capacity for such
Route. @Home shall pay $2,700 per Route mile for the right to use fiber in
connection with extending the Capacity to an additional Route usage of fiber on
any non-@Home Route. @Home shall pay an amount equal to the product of (a)
$2,700 per Route mile and (b) the Excess Expansion Percentage for the right to
use fiber in connection with an Existing Route Expansion. The route mileage for
new Routes shall be determined by AT&T's final as-built circuit designs.

                  7.3 Upgrade and Expansion Payment Terms. Upon agreeing to
participate in an upgrade or expansion @Home shall owe AT&T a deposit of 10% of 
the estimated cost of the upgrade or expansion. Upon Acceptance in accordance
with the Section entitled Testing and Acceptance and delivery of the Service
Components along the upgraded or expanded portion of the @Home Backbone Network,
@Home shall pay the remainder of the Upgrade Cost or the Expansion Cost;
provided however that @Home shall not be required to pay more than 110% of the
estimated cost given to @Home for such Upgrade or Expansion in the Upgrade
Response Notice, the Upgrade Notice or the Expansion Notice, as applicable. The
Section entitled Invoicing and Payment Terms shall apply to the Upgrade Cost and
the Expansion Cost.

         8. Audit of Certain Upgrade, Expansion and Discount-Related Invoices.
@Home may undertake an audit under this Section in connection with a billing
dispute or after payment of the relevant invoice to evaluate the accuracy of
pricing and calculations for such invoice. For a period of twelve (12) months
from the date payment of the relevant invoice by @Home is first due, AT&T agrees
to maintain records related to its purchases of equipment and services related
to an invoice, and to make such records available to a representative of @Home
(or, at AT&T's option, to a third-party auditor acceptable to both parties) at
reasonable times at AT&T headquarters on prior notice in connection with an
audit requested by @Home under this Section. All costs related to such audit
will be borne by @Home. All documents reviewed in connection with such an audit
shall be subject to confidential treatment as set forth in the Section entitled
Confidentiality. If the audit discloses an error in the pricing or discounts
made available to @Home, and such audit indicates @Home paid too much, AT&T and
@Home will promptly review the conclusions of the audit and, where AT&T concurs,
AT&T shall pay @Home the amounts due within 15 days of its concurrence. In the
event the audit reveals that @Home was charged too little, @Home shall pay the
difference within 30 days of receiving an invoice from AT&T therefor. If the
parties disagree, either party may seek to resolve the matter through
arbitration as set forth in the Section entitled Arbitration.

         9. Testing and Acceptance.

                  9.1 Testing. Prior to making any Capacity available to @Home
under this Agreement, AT&T shall test the Capacity on a Route-specific basis
("Testing") to ensure that the Capacity is in conformity with the technical
specifications set forth in Exhibit B (the "Specifications"). If any Testing
establishes that the Capacity does not conform to the Technical Specifications,
AT&T promptly shall correct such nonconformity and conduct additional Testing
prior to making the Service Components available to @Home.


<PAGE>   12
                                                                         Page 12


                  9.2 Acceptance. If AT&T determines, that for a particular
Route, that the Testing results show that the Capacity meets the Specifications
and that the Service Components are available for @Home's use, AT&T shall
provide @Home with written notice to that effect (the "Delivery Notice"). The
Delivery Notice shall include the Testing results, a description of the
available Service Components (including circuit identifiers) and the date the
Service Components will be available. Prior to providing the Delivery Notice
AT&T shall use commercially reasonable efforts to deliver @Home the applicable
rack spaces pursuant to a Collocation Agreement in the AT&T POP for installation
of its equipment. If @Home fails to give a Non-Acceptance Notice (defined below)
or makes a special request for an extension of the acceptance period (during
which period the applicable Commitment Date for the Route shall be tolled)
within 30 days after @Home's receipt of the Delivery Notice, @Home shall be
deemed to have accepted the Service Components for such Route(s) effective as of
such thirtieth day. The earliest of (i) such date, (ii) the date @Home informs
AT&T that it has accepted the Service Components, or (iii) the date that @Home
actually begins commercial use of the Service Component shall be deemed the
"Acceptance Date" for that Service Component and such Service Component shall be
"Accepted." @Home shall have the right to extend the acceptance period for 15
days upon written request to AT&T.

                  9.3 Non-Acceptance. If within the 30-day period (or the 45-day
period if applicable) described above, @ Home gives AT&T a written notice of any
nonconformity of the Capacity to the Specifications or stating that the Service
Components are not available for @ Home's use ("Non-Acceptance Notice"),
Acceptance shall not occur. A Non-Acceptance Notice must either specifically
identify the Specifications with which @Home contends the Capacity does not
conform, or provide an explanation of the manner and extent to which the Service
Component is not available. @Home will promptly upon AT&T's written request,
give reasonably specific additional information to AT&T regarding the claimed
nonconformity and , from the date of Non-Acceptance Notice until such
information is provided, any applicable Commitment Date shall be tolled. AT&T
shall use commercially reasonable efforts to correct such nonconformity and make
the Service Component available within 10 days of receipt of @Home's valid
Non-Acceptance Notice. Upon completion of such correction, AT&T shall notify
@Home by providing a Delivery Notice, after which @Home shall have 10 days for
Acceptance or for @Home to provide additional notice of a failure to deliver the
Service Components by providing a Non-Acceptance Notice. Such process shall be
repeated until Acceptance, provided however, if AT&T fails to correct any
nonconformity of any Capacity to the Technical Specifications or to provide the
Service Components within 90 days after the date of the first Delivery Notice,
@Home may at its option terminate this Agreement with respect to the affected
Route(s) only, upon written notice to AT&T. In such case, AT&T need no longer
deliver the affected Route(s), and @Home need no longer pay any amounts due for
such Route(s).

         10. Operation, Maintenance and Repair.

                  10.1 Purchase, Repair or Replacement of Electronic Equipment.
AT&T shall purchase, repair and replace all electronic equipment related to the
provision of the Service Components at all times.

                  10.2 Operating Standards. During the term of this Agreement,
AT&T shall operate the @Home Backbone Network in accordance with the same
standards with which AT&T operates the AT&T Network and in any case, with at
least the standard of care in the industry.

                                                                         Page 13


                  10.3 Maintenance and Repair. During the Term hereof, AT&T
shall be responsible, at its sole expense, for the emergency and non-emergency
maintenance, and repair of the AT&T Network and the @ Home Backbone Network, so
as to assure continuing conformity of the @Home Backbone Network with the
Specifications. If routine, scheduled maintenance of the @Home Backbone Network
is expected to result in any interruption of the Service, AT&T shall so notify
@Home in writing at least 10 business days prior to commencing such routine
maintenance. AT&T shall schedule major maintenance of the @Home Backbone Network
at a time selected by AT&T to limit adverse user impacts.

                  10.4 Use of Subcontractors. AT&T may contract with qualified
contractors for the performance of any maintenance and repair services
contemplated by this Agreement, including unaffiliated contractors, but shall
remain responsible for the performance of such services in accordance with the
requirements of this Agreement.

                  10.5 Response to Interruptions. Subject to geographic
limitations, AT&T shall exercise commercially reasonable efforts to respond to
any Unscheduled Interruption (defined below) involving AT&T facilities
delivering the Service within four hours, measured in each case from the time
that AT&T receives notice of an interruption and ending at the time a qualified
AT&T technician arrives at the site of the reported problem.

                  10.6 Credit for Total Interruptions.

                            10.6.1 A Total Interruption is: (a) any situation in
which @Home suffers a total loss of connectivity in one or more Routes, lasting
two or more hours, which loss is not caused by @Home, and that does not occur
within or as a result of equipment connections that @Home provides. In the event
of a Total Interruption that is due to circumstances within AT&T's reasonable
control (fiber cuts shall not be deemed to be within AT&T's reasonable control),
@Home shall be entitled to an allowance in the form of a credit against amounts
otherwise payable by @Home under this Agreement, calculated as set out below. No
credit will be provided for any scheduled interruption. Any credit shall be
applied to the next monthly maintenance invoice issued to @Home.

                            10.6.2 @Home shall be credited for each two hour
period of a Total Interruption within AT&T's reasonable control in a specific
Route at a rate of $500 for each such period of a Total Interruption for each
Route where the Total Interruption occurs, the duration of such Interruption
being measured from (i) the time of notice to AT&T's network control center that
a Total Interruption has occurred to (ii) the time of restoration of the
Service.

                            10.6.3 If there shall occur, within any period of 12
consecutive months, more than four Total Interruptions caused by factors within
AT&T's reasonable control on the AT&T Network, AT&T will demonstrate to @Home
actions taken by AT&T to reduce such Interruptions. If there shall occur more
than two additional Total Interruptions due to factors within AT&T's reasonable
control within the subsequent three month period, @Home may at its option
terminate this Agreement upon written notice to AT&T, but only with respect to
the affected Route(s).

                  10.7 Interference. In any instance in which AT&T believes in
good faith that @Home's use of the @Home Backbone Network is interfering
unreasonably with the use of 


<PAGE>   14
                                                                         Page 14


AT&T service by others or the operation of the AT&T Network, AT&T may
immediately restrict or suspend the Service Components, without liability on the
part of AT&T, and then notify @Home of the action that AT&T has taken and the
reason for such action. For purposes of the foregoing sentence, the normal usage
by @Home of all or any part of the Capacity shall be deemed to be reasonable. To
the extent doing so does not interfere with its ability to prevent such
interference, AT&T will attempt to limit any restriction or suspension under
this Section to the Service Components that are causing such interference.

                  10.8 Ongoing Service Quality Review. The Parties shall
establish an informal mechanism for maintaining communications channels between
their respective network staffs related to service quality on the Routes. In the
event that there arises a service quality issue that a party deems to be
significant and that is not resolved in a satisfactory manner through the
established mechanism, the dissatisfied party may escalate the matter to senior
management of the other party for resolution, at the level of an executive vice
president or higher.

         11. Relocation. Unless the circumstances make such notice
impracticable, AT&T shall give @Home at least 90 days prior written notice of
any scheduled relocation of any portion of the @Home Backbone Network, and as
much advance notice as possible of any unscheduled relocation. AT&T shall have
the right to direct any relocation of any portion of the @Home Backbone Network,
including but not limited to the right to determine the extent and timing of,
and the methods to be used for, such relocation; provided, however, that unless
otherwise agreed, any such relocation: (i) shall be constructed and tested in
accordance with the Specifications, and (ii) shall not result in any
Interruption in excess of two hours or degradation of the Service Components. In
the event an AT&T POP or a Third-Party POP is relocated or replaced, by a new
site, AT&T shall relocate the applicable @Home Service Components (including any
facilities necessary to continue the AT&T and third-party interconnections in
place immediately prior to the relocation or replacement). Any such relocation
shall be undertaken at no cost to @Home, except in cases where relocation is
accompanied by additions or other work to benefit @Home and for which @Home
agrees in writing to pay.

         12. Term of the Agreement. This Agreement is binding on the parties as
of the Effective Date and, subject to the termination provisions of this
Agreement, shall remain in effect for 20 years from the Acceptance Date of all
Routes listed on Exhibit D (the "Term") . This Agreement, including the Service
Components granted under this Agreement, may be renewed upon terms mutually
agreed upon by the parties in writing.

         13. Use of the Services and Restriction on Resale. @Home may use the
Service Components for any lawful purpose and @Home represents and warrants that
its use of the Service Components and its offering of services using the @Home
Backbone Network will comply with all applicable government codes, ordinances,
laws, rules, regulations and/or restrictions. @Home may sell, trade, exchange or
otherwise make available to any person or entity any service so long as @Home's
routers and packet switches or packet based successor equipment are used.

         14. Indemnification.

                                                                         Page 15


                  14.1 @Home shall indemnify, defend, and hold harmless AT&T and
its directors, officers, employees, agents, subsidiaries, affiliates, successors
and assigns from any and all third party claims, damages and expenses whatsoever
(including reasonable attorneys' fees) arising on account of or in connection
with @Home's use of the Service Components provided under this Agreement,
including but not limited to: (a) claims arising from any failure, breakdown,
interruption or deterioration of service components provided by AT&T to @Home or
service provided by @Home to third parties; and (b) claims of patent
infringement arising from combining or using services or equipment furnished by
AT&T in connection with services or equipment furnished by others. @Home's
indemnification obligations do not apply to claims for damages to real or
tangible personal property or for bodily injury or death negligently caused by
AT&T.

                  14.2 AT&T shall indemnify, defend, and hold harmless @Home and
its directors, officers, employees, agents, subsidiaries, affiliates,
successors, and assigns from all claims of patent infringement arising solely
from the use of the Services.

                  14.3 The parties hereby expressly recognize and agree that
each party's said obligation to indemnify, defend, protect and save the other
harmless is not a material obligation to the continuing performance of the
parties' other obligations, if any, hereunder. In the event that a party shall
fail for any reason to so indemnify, defend, protect and save the other
harmless, the injured party hereby expressly recognizes that its sole remedy in
such event shall be the right to bring an arbitration proceeding pursuant to the
terms of this Agreement against the other party for its damages as a result of
the other party's said failure to indemnify, defend, protect and save harmless.
These obligations shall survive the expiration or termination of this Agreement.

                  14.4 Nothing contained herein shall operate as a limitation on
the right of either party hereto to bring an action for damages against any
third party, including indirect, special or consequential damages, based on any
acts or omissions of such third party as such acts or omissions may affect the
construction, operation or use of the AT&T Network or the @Home Backbone
Network, as the case may be; provided, however, that each party hereto shall
assign such rights of claims, execute such documents and do whatever else may be
reasonably necessary to enable the other party to pursue any such action against
such third party.

         15. [Reserved]

         16. Limitation of Liability.

                  16.1 EXCEPT AS SET FORTH IN THE SECTIONS ENTITLED DELIVERY AND
LIQUIDATED DAMAGES, AND CREDIT FOR TOTAL INTERRUPTIONS OR AS OTHERWISE SPECIFIED
HEREIN, THE LIABILITY OF AT&T ASSOCIATED WITH THE INSTALLATION, PROVISION, USE,
MAINTENANCE, REPAIR, TERMINATION OR RESTORATION OF SERVICE COMPONENTS PROVIDED
PURSUANT TO THIS AGREEMENT SHALL NOT EXCEED AN AMOUNT EQUAL TO THE PRORATED
PORTION OF CHARGES FOR THE AFFECTED SERVICE COMPONENTS FOR THE PERIOD DURING
WHICH THAT SERVICE COMPONENT WAS AFFECTED.

                                                                         Page 16


                  16.2 NOTWITHSTANDING ANY PROVISION OF THIS AGREEMENT TO THE
CONTRARY, IN NO EVENT SHALL EITHER PARTY BE LIABLE TO THE OTHER PARTY FOR ANY
SPECIAL, INCIDENTAL, INDIRECT, PUNITIVE, RELIANCE OR CONSEQUENTIAL DAMAGES,
WHETHER FORESEEABLE OR NOT, ARISING OUT OF, OR IN CONNECTION WITH, TRANSMISSION
INTERRUPTIONS OR PROBLEMS, INCLUDING, BUT NOT LIMITED TO, DAMAGE OR LOSS OF
PROPERTY OR EQUIPMENT, LOSS OF PROFITS OR REVENUE, COST OF CAPITAL, COST OF
REPLACEMENT SERVICES, OR CLAIMS OF CUSTOMERS, WHETHER OCCASIONED BY ANY REPAIR
OR MAINTENANCE PERFORMED BY, OR FAILED TO BE PERFORMED BY, THE FIRST PARTY OR
ANY OTHER CAUSE WHATSOEVER, INCLUDING, WITHOUT LIMITATION, BREACH OF CONTRACT,
BREACH OF WARRANTY, NEGLIGENCE OR STRICT LIABILITY. THIS PARAGRAPH SHALL NOT BE
CONSTRUED TO LIMIT EITHER PARTY'S ABILITY TO RECOVER UNDER THE SECTION ENTITLED
INDEMNIFICATION WITH RESPECT TO CLAIMS OF THIRD PARTIES BROUGHT AGAINST SUCH
PARTY OR THE RIGHT TO RECOVER LIQUIDATED DAMAGES UNDER THE SECTIONS ENTITLED
DELIVERY AND LIQUIDATED DAMAGES AND OPERATION, MAINTENANCE AND REPAIR.

                  16.3 PURSUANT TO THIS SECTION, NO PARTY SHALL BE PREVENTED
FROM MAKING A CLAIM OR FILING SUIT AGAINST AN INDEPENDENT CONTRACTOR FOR
SPECIAL, INCIDENTAL, INDIRECT, PUNITIVE, RELIANCE OR CONSEQUENTIAL DAMAGES
ARISING OUT OF SUCH INDEPENDENT CONTRACTOR'S PERFORMANCE OF MAINTENANCE OR
REPAIR SERVICES FOR THE SYSTEM OWNER, BUT THE PARTY MAKING THE CLAIM OR FILING
SUIT AGREES THAT IT WILL NOT SEEK RECOVERY OF SUCH DAMAGES TO THE EXTENT SUCH
INDEPENDENT CONTRACTOR HAS A CONTRACTUAL OR COMMON LAW RIGHT OF RECOVERY AGAINST
OR AN INDEMNITY FROM THE OTHER PARTY.

                  17.2 Unless otherwise provided herein, notices shall be sent
by registered or certified U.S. Mail, postage prepaid, or by commercial
overnight delivery service, or by facsimile, and shall be deemed served or

         18. Confidentiality. The parties hereto agree that this Agreement and
the terms hereof are "Confidential Information" as defined in the Nondisclosure
Agreement dated as of September 8, 1998 between the parties. Notwithstanding the
terms of that agreement however, either party may disclose the contents of, or
information concerning, this Agreement to the extent required by law after using
reasonable efforts to consult with the other party regarding such disclosure
and, as applicable, using reasonable efforts to obtain confidential treatment
from the applicable regulatory agency regarding the pricing terms hereof.

         18A Use of Marks Nothing in this Agreement creates in a party any
rights in the other party's trade names, trademarks, service marks or any other
intellectual property. Except as may be otherwise agreed between the parties in
writing:

                  18A.1 Either party may use the other party's trade names,
trademarks, or service marks only to the extent such use is not prohibited by
this Agreement and is otherwise permitted by law (including but not limited to
the Lanham Act).

                  18A.2 In no event shall either party use or display, in
advertising or otherwise, any of the other party's logos, trade dress, trade
devices or other indicia of origin, or any confusingly similar logos, trade
dress, trade devices or indicia of origin.

                  18A.3 Neither party shall conduct business under the other
party's corporate or trade name, trademark, service mark, logo, trade dress,
trade device, indicia of origin or other symbol that serves to identify and
distinguish the other party from its competitors, or under any

confusingly similar corporate or trade name, trademark, service mark, logo,
trade dress, trade device, indicia of origin or other symbol.

                  18A.4 Neither party (the "First Party") shall indicate or
imply to any third party that the First Party is affiliated with the other
party, that the First Party is authorized by the other party to sell or provide
service to them, that the First Party is providing (or will provide) service to
such party jointly or in collaboration or partnership with the other party, or
as the agent of the other party, or that service provided by the First Party or
another carrier is provided by the other party.

                  18A.5 Except to the limited extent (if any) as may be required
under law, neither party shall indicate or imply to any existing or potential
end user that any portion of the service provided to the end user by a party is
provided by the other party or is carried over the other party's network or
facilities.

         19. Default.

                  19.1 A party may deliver to the other party a written "Notice
of Default" for: (i) failing to make any payment owed hereunder, when no bona
fide dispute exists (a "Monetary Default"); or (ii) the breaching by either
party or its agents, assigns or affiliates of any Material Provision; or (iii)
the filing or initiating of proceedings by or against a party seeking
liquidation, reorganization or other such relief under any federal or state
bankruptcy or insolvency law (a "Bankruptcy Proceeding"). Such Notice of Default
must prominently contain the following sentences in capital letters: "THIS IS A
FORMAL NOTICE OF A BREACH OF CONTRACT. FAILURE TO CURE SUCH BREACH WILL HAVE
SIGNIFICANT LEGAL CONSEQUENCES."

                  19.2 A party that has received a Notice of Default arising out
of a Monetary Default shall have 30 days to cure. If @Home fails to cure a
Monetary Default within the cure period, AT&T shall have the right to either (a)
suspend its performance obligations under this Agreement, (b) seek an award for
the past due balance, including interest and reasonable attorneys' fees, and/or
(c) require @Home to post a reasonable deposit or other adequate assurance of
payment as a condition of continuing performance by AT&T. Notwithstanding the
foregoing, AT&T may not disconnect service or revoke the IRU with respect to any
Route except for non-payment of the IRU Fee with respect to any Route.

                  19.3 A party that has received a Notice of Default arising out
of an alleged breach of a Material Provision shall have 30 days to cure the
alleged breach. If the defaulting party shall have commenced actions in good
faith to cure such defaults which are not susceptible of being cured during such
30-day period, such period shall be extended (but not in excess of 90 additional
days) while such party continues such actions to cure. If such party fails to
cure the breach within the applicable cure period, as long as such default shall
be continuing, the non-defaulting party shall have the right to either (a)
suspend its performance or payment obligations under this Agreement, (b) seek an
order of specific performance, and/or (c) seek the award of compensatory
damages. Any event of default by either party may be waived under the terms of
this Agreement at the other party's option.

         20. Termination.

                  20.1 Upon the expiration of the Term of this Agreement, the
Services Components shall terminate and @Home shall owe AT&T no additional
consideration.

                  20.2 Notwithstanding the foregoing, no termination of this
Agreement shall affect the rights or obligations of any party hereto with
respect to any payment hereunder for services rendered prior to the date of
termination or pursuant to the Sections entitled Indemnification, or Arbitration
herein.

         21. Force Majeure. If, by reason of any Force Majeure Event (as
hereinafter defined), a party shall be unable to carry out any of its
obligations (other than the payment of monetary amounts due) under this
Agreement and that party gives the other party prompt written notice thereof,
then, except as otherwise set forth herein, any such obligations shall be
suspended to the extent made necessary by reason of such Force Majeure Event
during its continuance, provided that such party attempts to eliminate insofar
as is reasonably possible the effect of such force majeure with all reasonable
dispatch. The term "Force Majeure Event" shall mean: (i) an act of God, (ii)
fire, (iii) flood, (iv) explosion (v) material shortage or unavailability not
resulting from the responsible Party's failure to timely place orders or take
other necessary actions therefor, (vi) war, civil disorder, earthquake or labor
strikes or (vii) national emergency. The party claiming relief under this
Section shall promptly notify the other in writing of the existence of the
event(s) (i) through (vii) relied on, the expected duration of the Force Majeure
Event, and the cessation or termination of said event.

         22. Arbitration

                  22.1 An "Arbitrable Dispute" is any dispute or disagreement
arising between @Home and AT&T in connection with this Agreement in which the
dollar amount in dispute is less than one million dollars ($1,000,000) or which
involves quality issues not settled by the parties pursuant to the section
entitled ongoing Service Quality Review. Any Arbitrable Dispute which is not
settled to the mutual satisfaction of @Home and AT&T within thirty (30) days
from the date that either party informs the other in writing that such dispute
or disagreement exists, shall be settled by arbitration in San Francisco,
California in accordance with the Commercial Arbitration Rules of the American
Arbitration Association in effect on the date that such notice is given. If the
parties are unable to agree on a single arbitrator within 15 days from the date
of receipt of the notice notifying a party of a dispute or disagreement, each
party shall select an arbitrator within 15 days and the two arbitrators shall
select a third arbitrator within 10 days. The decision of the arbitrator(s)
shall be final and binding upon the parties and shall include written findings
of law and fact, and judgment may be obtained thereon by either party in a court
of competent jurisdiction. Each party shall bear the cost of preparing and
presenting its own case. The cost of the arbitration, including the fees and
expenses of the arbitrator(s), shall be shared equally by the parties hereto
unless the award otherwise provides. The arbitrator(s) shall be instructed by
the parties to establish procedures such that a decision can be rendered by the
arbitrator(s) within 60 days of their appointment.

                  22.2 The obligation herein to arbitrate shall not be binding
upon any party with respect to requests for preliminary injunctions, temporary
restraining orders, specific performance or other procedures in a court of
competent jurisdiction to obtain interim relief 


<PAGE>   20
                                    Page 20


when deemed necessary by such court to preserve the status quo or prevent
irreparable injury pending resolution by arbitration of the actual dispute.

         23. Waiver. The failure of either party hereto to enforce any of the
provisions of this Agreement, or the waiver thereof in any instance, shall not
be construed as a general waiver or relinquishment on its part of any such
provision, but the same shall nevertheless be and remain in full force and
effect.

         24. Taxes.

                  24.1 @Home shall pay any applicable local, state and federal
taxes, levied upon the sale, installation, use or provision of the Services
Components, the IRU, or any equipment provided under this Agreement, except to
the extent @Home provides a valid tax exemption certificate to AT&T prior to the
delivery thereof.

                  24.2 AT&T shall be responsible for and shall timely pay any
and all (i) taxes and franchise, license and permit fees based on the physical
location of the AT&T Network and the @Home Backbone Network; and (ii)
right-of-way payments on the AT&T Network and the @Home Backbone Network. Each
of AT&T and @Home shall be responsible for any and all sales, use, income, gross
receipts or other taxes assessed on the basis of revenues received by such party
due to its use of the AT&T Network and the @Home Backbone Network, respectively.

         24A Equipment. AT&T shall retain title to all of its equipment and
facilities used to meet its performance obligations this Agreement.


         25. Governing Law. This Agreement shall be governed by and construed in
accordance with the domestic laws of the State of New York without reference to
its choice of law principles.

         26. Rules of Construction.

                  26.1 The captions or headings in this Agreement are strictly
for convenience and shall not be considered in interpreting this Agreement or as
amplifying or limiting any of its content. Words in this Agreement which import
the singular connotation shall be interpreted as plural, and words which import

parties or objects referred to may require.

                  26.2 Unless expressly defined herein, words having well-known
technical or trade meanings shall be so construed. All listing of items shall
not be taken to be exclusive, but shall include other items, whether similar or
dissimilar to those listed, as the context reasonably requires.

                  26.3 Except as set forth to the contrary herein, any right or
remedy of AT&T or @Home shall be cumulative and without prejudice to any other
right or remedy, whether contained herein or not.

performance is reasonable and timely.

         27. Assignment. Neither Party shall assign or otherwise transfer this
Agreement or its rights or obligations hereunder to any person or entity without
the prior written consent of the other party, which shall not be unreasonably
withheld or delayed; provided, however, that either party shall have the right,
without the consent of the other, to grant a security interest in this Agreement
or the rights hereunder as collateral to any lender, or to assign or otherwise
transfer the Agreement to any person or entity that controls, is under the
control of, or is under common control with the assigning party, or any
corporation into which such party may be merged or consolidated or that
purchases all or substantially all of the assets of such party used by such
party in connection with the Capacity Service; provided, further, that any such
assignment or transfer shall be subject to the other party's rights under this
Agreement and any assignee or transferee (other than a lender, in the case of a
security interest) shall continue to perform the assigning or transferring
party's obligations under this Agreement. This Agreement is intended to pass by
operation of law to any party to whom AT&T may assign all or substantially all
of the AT&T Network, but only to the extent that it is in fact assigned.

         28. Representations and Warranties. Each party represents and warrants

ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. AT&T DOES
NOT WARRANT THAT THE SERVICES WILL BE UNINTERRUPTED OR ERROR-FREE, OR THAT THE
SERVICES WILL MEET CUSTOMER'S REQUIREMENTS OR THAT THE SERVICES WILL PREVENT

                  28.5 Its execution of and performance under this Agreement
shall not violate any applicable existing regulations, rules, statutes, or court
orders of any local, state or federal governmental agency, court or body.

         29. Entire Agreement; Amendment. This Agreement constitutes the entire
and final agreement and understanding between the parties with respect to the
subject matter hereof and supersedes all prior agreements relating to the
subject matter hereof, which are of no further force or effect. The Exhibits
referred to herein are integral parts hereof and are hereby made a part of this
Agreement. This Agreement may only be modified or supplemented by an instrument
in writing executed by a duly authorized representative of each party.

         30. No Personal Liability. Each action or claim against any party
arising under or relating to this Agreement shall be made only against such
party as a corporation, and any liability relating thereto shall be enforceable
only against the corporate assets of such party. No party shall seek to pierce
the corporate veil or otherwise seek to impose any liability relating to, or
arising from, this Agreement against any shareholder, employee, officer or
director of the other party. Each of such persons is an intended beneficiary of
the mutual promises set forth in this Section and shall be entitled to enforce
the obligations of this Section.

         31. Relationship of the Parties. The relationship between AT&T and
@Home shall be that of independent contractors and not of principal and agent,
franchiser and franchisee, dealer and distributor, partners or joint venturers
for one another, and nothing contained in this Agreement shall be deemed to
constitute a partnership or agency agreement between them for any purposes,
including, but not limited to federal income tax purposes. AT&T and @Home, in
performing any of their obligations hereunder, shall be independent contractors
or independent parties and shall discharge their contractual obligations at
their own risk. Each party acknowledges that nothing in this Agreement
diminishes or restricts in any way the rights of the parties to engage in
competition with each other. Each party acknowledges that it remains at all
times solely responsible for the success and profits of its own business.

         32. Export Regulations. The parties acknowledge that any products,
software, and technical information (including, but not limited to, services and
training) provided under this Agreement are subject to U.S. export laws and
regulations and any use of or transfer of such products, software and technical
information must be authorized under those regulations. @Home agrees that it
will not use distribute, transfer or transmit the products, software or
technical information (even if incorporated into other products) except in
compliance with U.S. export regulations. If requested by AT&T, @Home also agrees
to sign written assurances and other export-related documents as may be required
for AT&T to comply with U.S. export regulations.

         33. Severability. If any term, covenant or condition herein shall, to
any extent, be invalid or unenforceable in any respect under the laws governing
this Agreement, the remainder of this Agreement shall not be affected thereby,
and each term, covenant or condition of this Agreement shall be valid and
enforceable to the fullest extent permitted by law.

         34. Counterparts. This Agreement may be executed in one or more
counterparts, all of which taken together shall constitute one and the same
instrument.
