At Home Corporation
425 Broadway Street
Redwood City, CA 94603
Attention:  Mr. Mark O'Leary

Dear Mr. O'Leary:

          Reference is hereby made to the term sheet attached hereto as Annex A
(the "Term Sheet"), which sets forth the principal terms that AT&T Corp.
("AT&T") and At Home Corporation ("At Home" and, together with AT&T, the
"Parties") will, subject to provisions and conditions of this Letter of
Agreement, incorporate into a definitive agreement between them (the
"Agreement", which term shall include all definitive documentation that may be
necessary in connection with the transactions contemplated by the Term Sheet).
Pursuant to the Agreement, AT&T would assume certain functions currently
performed by At Home and, in connection therewith, acquire certain At Home
assets, offer employment to certain At Home personnel, and provide services to
At Home.

          1.   Negotiation of Definitive Agreements.  (a)  The Parties will
commence immediately and in good faith to negotiate the Agreement, which will
supersede the Term Sheet. The Agreement will contain provisions incorporating
the terms set forth in the Term Sheet, together with provisions customary in the
case of transactions of the type described herein and therein, and such other
provisions as are reasonable and appropriate in the context of the transactions
contemplated hereby and thereby or otherwise mutually agreed by the parties.

          (b)  The Parties will use their best efforts to complete negotiation
of the Agreement as promptly as practicable and, in any event, no later than
June 16, 2001.

          (c)  The Parties will execute the Agreement promptly upon completion
of such negotiation. Notwithstanding the foregoing, At Home shall not be
obligated to execute the Agreement upon completion of such negotiation unless
the independent directors of At Home (i.e., those who are not affiliated with
AT&T) determine in good faith, after considering the alternatives available to
At Home, that the Agreement is in the best interest of and fair to At Home and
its shareholders.

 
          2.   Effectiveness; Conditions.  The transactions contemplated herein
and by the Term Sheet shall be conditioned upon (a) the absence of any statute,
rule, regulation, executive order, decree or injunction having been enacted,
entered, promulgated or enforced by any governmental entity or judicial or
regulatory authority (each, a "Governmental Authority") that has the effect of
making such transactions illegal or otherwise prohibiting the consummation of
such transactions materially as contemplated by the Term Sheet; (b) receipt or
expiration of any other material approval or waiting period required by a
Governmental Authority, if any, including if applicable under the Hart-Scott-
Rodino Antitrust Improvements Act of 1976, as amended, and (c) completion of
definitive documentation as contemplated by paragraph 1 of this Letter of
Agreement.

          3.   Termination.  (a)  This Letter of Agreement may be terminated at
any time by mutual written agreement of the Parties hereto.

          (b)  If any of the conditions set forth in clauses (2)(a) or (b)
becomes permanently incapable of being satisfied by virtue of any order, decree
or ruling or other action taken by any Governmental Authority that is final and
nonappealable, then either Party hereto (other than any Party whose failure to
comply with its obligations hereunder shall have caused such failure to occur or
who has failed to use its reasonable best efforts to cause any such order,
decree or ruling to be lifted) may terminate this Letter of Agreement by sending
written notice to the other Party.

          (c)  This Letter of Agreement may be terminated by either Party, upon
written notice to the other, if the definitive documentation contemplated by
paragraph 1 has not been completed by June 16, 2001.

          (d)  This Letter of Agreement will automatically terminate in the
event that At Home exercises its right not to execute the Agreement pursuant to
the second sentence of paragraph 1(c).

          (e)  Upon any termination in accordance with this paragraph 3, this
Letter Agreement (including the Term Sheet) shall be null and void and of no
further force or effect without further liability to either Party, except that
the provisions of this paragraph 3 and of paragraph 4 shall continue in full
force and effect following the termination or expiration of this Letter of
Agreement.

          4.   MISCELLANEOUS.

          (a)  Public Disclosures.  Each Party will use its reasonable best
efforts to consult with the other Party as to the content of any public
disclosure of the terms of this Letter of Agreement that such first Party
determines is required, and will give reasonable consideration to such other
Party's suggestions prior to making such disclosure. AT&T will not discuss the
arrangements contemplated by the Term Sheet with employees or contract employees
of At Home except in accordance with the employee transition plan described in
the Term Sheet.

 
          (b)  Expenses.  Except as otherwise provided herein or in the Term
Sheet, or as hereafter mutually agreed by AT&T and At Home, all costs and
expenses incurred in connection with this Letter of Agreement and the
transactions contemplated hereby shall be paid by the Party incurring such costs
and expenses. At Home shall reimburse AT&T for the salary expenses and
reasonable out-of-pocket expenses actually incurred by AT&T for Hossein
Eslambolchi and the other AT&T engineers and employees working with him on
behalf of At Home, who are listed in Annex B hereto (which Annex may be amended
or supplemented from time to time by mutual agreement of the Parties). The
reimbursement period for salary expenses will be from the date of this Letter of
Agreement through the earlier of the date the Agreement becomes effective and
the date such persons cease performing services on behalf of At Home. The
reimbursement period for reasonable out-of-pocket expenses will be from the date
such persons commenced work on behalf of At Home through the earlier of the date
the Agreement becomes effective and the date such persons cease performing
services on behalf of At Home.

          (c)  No Third-Party Beneficiaries.  This Letter of Agreement
(including the Term Sheet) shall be only for the benefit of the Parties and is
not intended for the benefit of any other party.

          (d)  Governing Law.  This Agreement shall be governed by, and
construed and enforced in accordance with, the laws of the State of Delaware
applicable to contracts executed in and to be performed entirely within that
State, without giving effect to the conflicts of laws principles thereof.

          (e)  Amendment; Waiver.  This Letter of Agreement (including the Term
Sheet) may be amended at any time pursuant to a writing executed by both
Parties. Either Party may (i) extend the time for the performance of any of the
obligations or other acts of the other or (ii) waive compliance with any of the
agreements or conditions contained herein. Any agreement on the part of a Party
to any such extension or waiver shall be valid only as against such Party and
only if set forth in an instrument in writing signed by such Party.

          (f)  Counterparts.  This Letter of Agreement may be executed in
counterparts, each of which shall be deemed an original and all of which shall
constitute one and the same instrument.

          (g)  Non-solicitation.  There will be a non-solicitation period
lasting from the date of this Letter of Agreement until the earlier of the
execution of the Agreement or April 30, 2003. During the non-solicitation
period, (i) AT&T shall not hire or solicit any employee or contract employee of
At Home involved in the negotiations or implementation of the outsourcing
arrangement contemplated by this Letter of Agreement or encourage any such
employee or contract employee to leave such employment and (ii) At Home shall
not hire or solicit any employee or contract employee of AT&T involved in the
negotiations or implementation of the outsourcing arrangement contemplated by
this Letter of Agreement or encourage any such employee or contract employee to
leave such employment. Notwithstanding the foregoing, either Party may engage in
general solicitations of employment not specifically targeted at any of the
other Party's employees or contract employees, and either Party may hire former
employees 

 
or contract employees of the other Party who have left employment with the other
Party without any prohibited solicitation or encouragement by such first Party.

          (h)  Notices.  Except as otherwise provided in this Letter of
Agreement or the Term Sheet, all notices, requests, claims, demands, waivers and
other communications hereunder shall be in writing and shall be deemed to have
been duly given when delivered by hand, when delivered personally or by courier,
when received by facsimile transmission if promptly confirmed by telephone, or
three days after being deposited in the U.S. mail (registered or certified mail,
postage prepaid, return receipt requested), as follows:

Accepted and Agreed as of the date first above written:

AT HOME CORPORATION


By:  /s/    
   ----------------------------------------
   Name: 
   Title:   

 
                                                                         ANNEX A

                                  Term Sheet


1.   AT&T and At Home will enter into a long-term contract for the provision
     Engineering and Operations Services by AT&T to At Home, including the
     services described in Exhibit 1 to this Term Sheet. Engineering Services
     relating to network operations and capacity planning and delivery will be
     within scope, as will network systems engineering, architecture and
     operations/integration testing. Engineering projects not related to network
     functions (such as client software development) will not be in scope.
     Engineering related to the development of market service descriptions will
     not be within scope, unless otherwise agreed. Operation and implementation
     of the market service descriptions will be within scope.

2.   In addition to the services described in paragraph 1, the parties will,
     upon consummation of the definitive agreements (collectively, the
     "Agreement"), replace the IRU Capacity Agreement dated as of December 19,
     1998 between At Home and AT&T (the "IRU") with a long-term lease pursuant
     to which At Home will obtain transport services to meet its requirements
     from AT&T. AT&T will pay At Home an amount (the "IRU Price") equivalent to
     the greater of (i) $75 million, or (ii) the fair market value of the IRU,
     not to exceed $85 million. At Home will make lease payments in accordance
     with the pricing parameters set forth in Exhibit 2 (provided however that
     if the price paid is greater than $75 million, the prices listed will be
     adjusted accordingly). In addition to the lease, At Home will obtain from
     AT&T services necessary to support the At Home backbone infrastructure, as
     well as its local transport requirements. Where At Home is under current
     contract with other suppliers, AT&T will assume management of those
     contracts on At Home's behalf, with the intention to move the transport to
     AT&T as soon as feasible where this does not disadvantage At Home. The
     lease agreement will contain the same essential terms as the IRU, and will
     provide that AT&T will finance capacity upgrades on commercially reasonable
     terms to be set forth in the lease agreement. The lease agreement will have
     a term of twenty (20) years, independent of the length of the outsourcing
     arrangement.

     In order to provide the services contemplated, AT&T, at its option, may
     acquire, at book value, certain assets (to be specifically identified in
     the definitive documentation) from At Home which enable AT&T to integrate
     use of those assets with AT&T assets in order to achieve efficiencies in
     providing service to At Home. Among the assets that are subject to transfer
     are At Home network assets, test lab assets and infrastructure assets
     (including the network operations centers in Redwood City and Toronto,
     Canada). In addition, AT&T shall be entitled to offer At Home personnel (to
     be specifically identified in the definitive documentation) associated with
     such functions employment at AT&T, and At Home will use its reasonable best
     efforts to facilitate and support such transfer of personnel.

 
3.   Reference is made to the Service Level Plan (the "TSLP") among At Home,
     Comcast Corporation ("Comcast"), and Cox Communications ("Cox"), dated
     March 28, 2000. At Home shall not enter into any service level commitments
     with Cox or Comcast, or any person or entity, in each case that could
     require compliance by AT&T under the arrangements contemplated by this Term
     Sheet, without AT&T's consent, which consent will not be unreasonably
     withheld. Where AT&T does so consent, and the performance of the functions
     underlying the SLA have been outsourced and are within the sole control and
     responsibility of AT&T, the parties expectation is that AT&T's SLAs to At
     Home will parallel the performance metrics so agreed by At Home with third
     parties, provided however, that the parties also agree that the financial
     consequences attached to those SLAs will not be parallel, and that AT&T's
     maximum annual liability will be as set forth in paragraph 9. At Home
     represents that as of the date of the Letter of Agreement, it has not
     entered into any SLAs with Cox, Comcast, or any person or entity, in each
     case that could require compliance by AT&T under the arrangements
     contemplated by this Term Sheet. AT&T shall not be responsible to At Home's
     customers, and shall only be responsible to At Home to the extent agreed to
     in the definitive agreements between them.

4.   AT&T agrees that it will not integrate network assets of At Home with those
     of AT&T unless it is able to maintain a mutually agreed standard for
     logical separation of At Home's traffic. However, At Home acknowledges that
     the price savings offered by AT&T in Exhibit 2 are based on AT&T's ability
     to integrate network assets of At Home with those of AT&T to gain
     efficiencies. Therefore, if AT&T is unable to integrate network assets
     while maintaining the agreed-upon standard for logical separation of At
     Home's traffic, the parties agree that the pricing for the services
     provided will be renegotiated, with the understanding that those prices
     will not exceed what it would cost At Home to meet the same performance
     standards on its own. In order to establish a baseline to measure the cost
     savings described above, At Home and AT&T will create a baseline unit cost
     metric that, beginning with projected costs as set forth in At Home's plan
     of record (taking into account SLAs that may be entered with Cox and
     Comcast and the projected volumes over the relevant contract period)
     approved by At Home's board of directors on or prior to the date hereof,
     establish what At Home's costs are, and are projected to be without AT&T's
     technical assistance or the projected Outsourcing arrangement, including
     network integration.

5.   The Agreement will contain provisions relating to AT&T's operation of the
     network with a view to preserving At Home's current business opportunities.

6.   [Reserved] 
  
7.   The definitive agreements shall incorporate the following additional terms:

     a.   During the term of the Agreement, AT&T will be appointed by At Home as
          its limited agent for obtaining and managing the tariffed or
          contracted telecommunication transport services, including both
          backbone and local 

 
          transport services. At Home agrees to notify all appropriate third
          parties of such appointment. AT&T's obligations as agent are limited
          to the obtaining and management of the tariffed or contracted
          telecommunication transport services, including those provided by AT&T
          and its affiliates. It is understood that AT&T will migrate At Home to
          AT&T transport services as soon as feasible, provided this does not
          disadvantage At Home.

     b.   AT&T may purchase from At Home assets that AT&T determines are
          necessary or appropriate to perform the services contemplated
          hereunder in an efficient manner, which assets will be specified in
          the definitive documentation. Any assets purchased will be purchased
          by AT&T at book value. AT&T's fees will thereupon be modified to
          provide for the recovery of the purchase price over the subsequent 36
          months. (This shall not apply to the IRU, the pricing terms for which
          are set forth separately in Exhibit 2.) Such recovery of the purchase
          price and increase in AT&T's fees will correspond to the charges
          ordinarily charged by a leasing company operating at arm's length from
          both parties for a "sale and leaseback" of such assets using an 8%
          interest rate. While there is any unresolved dispute between the
          parties concerning the increase in AT&T's fees for the recovery of the
          purchase price of the assets, At Home will make the assets and any
          subsequent appropriate or necessary replacement assets, as reasonably
          determined by AT&T, available to AT&T at no charge.

     c.   At Home will provide to AT&T, at no charge to AT&T, the use of all
          assets owned or leased by At Home that are required to perform the
          Services unless and until such assets may be acquired by or assigned
          to AT&T, as specifically to be identified in the definitive
          documentation. At Home will be responsible, at its expense, to obtain
          any necessary consents, licenses, sublicenses or approvals as are
          necessary to allow AT&T to use such assets to provide the services. At
          Home will retain all expenses incidental to ownership of such assets,
          including but not limited to depreciation, taxes and insurance
          expenses, until such assets are acquired by or assigned to AT&T.

     d.   At Home will assign to AT&T, at no charge to AT&T, all necessary or
          appropriate third-party licenses and agreements currently used by At
          Home in the operations, maintenance and management of At Home's
          telecommunications networks, as set forth in the definitive
          documentation. At Home will be responsible for obtaining the consents
          of third parties and for paying any assignment fee, transfer fee or
          other costs in connection with the assignment of such licenses and
          agreements to AT&T.

     e.   AT&T and At Home will work together to develop a mutually agreeable
          employee transition plan. AT&T will allow At Home to provide input on
          the packages to be offered to At Home employees to be moved to AT&T;
          provided that the ultimate terms shall be in AT&T's sole discretion.
          The plan 

 
          will also specify the timing and conditions as to when and how
          employees will be approached about joining AT&T. AT&T will offer
          employment, at AT&T's discretion, to selected At Home employees
          currently engaged in the management, operations and maintenance of At
          Home's telecommunications networks. The terms, including duration, of
          such employment will be agreed upon between the Parties and set forth
          in a separate letter agreement, or in an attachment to the definitive
          agreement. The definitive agreements will determine, based on the
          employees moving to AT&T, whether or not it is efficient for both
          parties for AT&T to assume any At Home leases, but any such assumption
          is subject to mutual agreement of the parties. At Home will make
          available sufficient space and associated services to house the
          personnel and assets assumed by AT&T. The parties will collaborate to
          enable AT&T to integrate those people and assets in as few locations
          as possible, and to enable At Home to reduce its total space
          requirements and reduce its real estate expense. Provided that At Home
          provides space and associated requirements to AT&T without charge, as
          described above, AT&T will meet its cost reduction targets under this
          agreement even if it chooses to move people or assets to its own
          facilities, such cost reduction targets to be calculated using both a
          baseline and a measurement of actual cost reductions that does not
          include real estate costs.

     f.   At Home will be responsible for all claims of any nature by any At
          Home's employees or former employees related to salaries, At Home
          employee benefit plans, severance, termination, employment offers with
          AT&T, transition to employment with AT&T, or related in any manner to
          the definitive agreement or to such employee's employment at At Home
          prior to the effective date of the definitive agreement. At Home will
          pay all taxes, however denominated, arising by reason of AT&T's
          performance of the services or consummation of any transaction
          contemplated by the definitive agreement, except for taxes on AT&T's
          net income. Without limiting the foregoing, taxes payable by At Home
          shall include any sales, use or excise tax on the services, and all
          filing, recording and transfer fees arising in connection with the
          sale, assignment or conveyance of At Home's assets to AT&T.

     g.   The term of the definitive agreement will commence on the effective
          date thereof and, unless earlier terminated or extended in accordance
          with the terms of the agreement, will expire five years thereafter.
          Six months prior to the expiration date, the parties will notify each
          other regarding their willingness to extend for an additional five (5)
          year period. If AT&T declines to extend, it will offer a transition
          period of one year following the scheduled expiration during which it
          will continue to provide services to At Home, subject to the
          transition plan to be agreed to as part of the definitive agreements.
          The Agreement will contain mutually acceptable unwind provisions,
          which may differ depending on the timing or cause of termination.

 
     h.   For a reasonable period prior to the effective date and thereafter
          during the term, At Home will provide all reasonably necessary
          assistance and cooperation to AT&T in all matters relating to the
          agreement, including providing reasonable access to At Home's key
          personnel and network management records and information.

     i.   The definitive agreement will include provisions governing AT&Ts
          rights of access to customer locations and information necessary to

     j.   AT&T will not have any interest in any proprietary specifications,
          designs, patents, plans, drawings, software, processes and procedures,
          or other technical and business information of or developed
          independently by At Home (the "At Home Information") disclosed to AT&T
          by or on behalf of At Home in connection with the Agreement. At Home
          will grant to AT&T a nonexclusive, nontransferable, royalty-free
          license (without the right to sublicense, except to affiliates) during
          the term to use such At Home Information, but only to perform the
          services under the agreement for At Home.

     k.   At Home will not have any interest in any proprietary specifications,
          designs, patents, plans, drawings, software, processes and procedures,
          or other technical and business information of or developed
          independently by AT&T (the "AT&T Information") disclosed to At Home by
          or on behalf of AT&T in connection with the agreement. AT&T will grant
          to At Home a nonexclusive, non-transferable, royalty-free license
          (without the right to sublicense, except to affiliates) during the
          term to use such AT&T Information in connection with receipt of the
          services under the Agreement.

     l.   Unless otherwise agreed, each party will own the intellectual property
          it creates in connection with any development work undertaken on
          behalf of At Home. The definitive agreements will also delineate with
          respect to the present 58 development projects currently being
          undertaken by At Home whether there are different arrangements that
          should apply, where the development is uniquely of interest to one of
          the parties.

     m.   Each Party's liability to the other for its failure to perform its
          obligation under the agreement will be limited to direct damages
          actually incurred. Neither Party will be liable to the other for any
          indirect, consequential, incidental, special or punitive damages,
          including but not limited to loss of data, interest, revenue or
          profits (excluding AT&T's anticipated profit under the Agreement) or
          interruption of business, except for (1) claims involving third
          parties covered under the indemnity provisions of the agreement, and
          (2) injury to a person or damage to property resulting from gross
          negligence or willful misconduct.

 
8.   It may be necessary for both parties to disclose to each other certain
     information that is marked or otherwise specifically identified as
     proprietary (including the At Home Information and the AT&T Information,
     "Information"). Any Information disclosed by the parties will continue to
     be the property of the disclosing party. Each party shall hold all
     Information provided by the other in confidence, use it only for the
     purpose of providing or using the services during the term of the Letter of
     Agreement and the definitive agreement contemplated hereby and not disclose
     it to others. Upon written request or upon the receiving party's
     determination that it no longer has a need for such Information, the
     receiving party shall return to the disclosing party or destroy all
     Information disclosed hereunder. The obligations set forth in this
     paragraph will survive any termination of the Letter of Agreement.

9.   AT HOME'S EXCLUSIVE REMEDY FOR ANY CLAIM AGAINST AT&T SHALL BE LIMITED TO
     PROVEN DIRECT DAMAGES IN AN AMOUNT NOT TO EXCEED AMOUNTS PAID TO AT&T
     EXCLUDING THE COST OF EQUIPMENT, OR $5,000,000 PER ANNUM, WHICHEVER IS
     LESS. AT&T SHALL NOT BE RESPONSIBLE FOR INDIRECT, SPECIAL, CONSEQUENTIAL OR
     INCIDENTAL DAMAGES OF ANY NATURE. AT&T MAKES NO WARRANTY, GUARANTEE OR
     REPRESENTATION, EXPRESS OR IMPLIED, RELATING TO THE PERFORMANCE OF THE
     SERVICE. AT&T EXPRESSLY DISCLAIMS ANY EXPRESS OR IMPLIED WARRANTY OF
     MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. AT HOME'S SOLE REMEDY
     WITH RESPECT TO THE EQUIPMENT IS THE WARRANTY PROVIDED BY THE EQUIPMENT
     MANUFACTURERS TO THE END-USER OF SUCH EQUIPMENT.

     AT&T'S EXCLUSIVE REMEDY FOR ANY CLAIM AGAINST AT HOME SHALL BE LIMITED TO
     PROVEN DIRECT DAMAGES IN AN AMOUNT NOT TO EXCEED $5,000,000 PER ANNUM;
     PROVIDED THAT THE FOREGOING LIMITATION SHALL NOT APPLY TO AT HOME'S
     OBLIGATIONS TO AT&T FOR PAYMENTS PROVIDED FOR HEREUNDER AND IN THE
     DEFINITIVE AGREEMENT. AT HOME SHALL NOT BE RESPONSIBLE FOR INDIRECT,
     SPECIAL, CONSEQUENTIAL OR INCIDENTAL DAMAGES OF ANY NATURE.

10.  Any supplement, modification or waiver of any provision of this Term Sheet
     must be in writing and signed by an authorized representative of both
     parties.

11.  The definitive agreement will not be assignable by either party without the
     prior written consent of the other, except that AT&T will have the right to
     assign the agreement, in whole or in part, to a present or future affiliate
     or successor and to assign its right to receive payments under the
     agreement. AT&T will be entitled to subcontract for work to be performed
     under the agreement. The parties intend the agreement to be binding on
     successors in interest. Should At Home experience a change of control: (i)
     the current provisions of the IRU will govern the comparable provisions of
     the lease; and (ii) AT&T shall have the right to terminate the outsourcing
     portion of the Agreement, subject to an 18 month transition period.

 
12.  AT&T will be an independent contractor under the agreement and the
     transactions contemplated by this Term Sheet. Nothing in the Letter of
     Agreement, this Term Sheet or the definitive agreement shall be deemed to
     constitute either party the agent of the other.
