Item 5: Other Events

               On January 19, 1999, Excite, Inc. (the "Company"), At Home
Corporation ("At Home") and Countdown Acquisition Corp. ("Merger Sub") entered
into a definitive Agreement and Plan of Reorganization (the "Merger Agreement").
Pursuant to the Merger Agreement and subject to the terms and conditions set
forth therein, the Merger Sub will be merged with and into the Company (the
"Merger"), with the Company surviving the Merger and becoming a wholly-owned
subsidiary of At Home. At the effective time of the Merger, all outstanding
shares of the Company's capital stock will be exchanged for shares of At Home
Series A Common Stock, and options and warrants to purchase Company capital
stock will exchanged for an option or warrant, as applicable, to purchase shares
of At Home Series A Common Stock and the exercise price and number of shares of
Company capital stock subject to each such Company option or warrant will be
appropriately adjusted to reflect such exchange ratio. Any outstanding
convertible debt at the effective time of the Merger will thereafter be
convertible into the number of shares of At Home Series A Common Stock to which
a holder of Company common stock would have been entitled to receive if such
holder had converted such convertible debt into Company common stock prior to
the effective time of the Merger. Each share of Company common stock will be
exchanged for 1.041902 shares of At Home Series A Common Stock. The transaction
will qualify as a tax-free reorganization and will be accounted for as a
purchase. Following the transaction, George Bell, Chief Executive Officer of the
Company, will continue in that role as the Company becomes a subsidiary of At
Home, reporting to Tom Jermoluk, Chairman and Chief Executive Officer of At
Home. In addition, Mr. Bell will be appointed as a member of the At Home Board
of Directors.

               In connection with the execution of the Merger Agreement, the
Company and At Home entered into a Stock Option Agreement (the "Stock Option
Agreement"), pursuant to which the Company granted to At Home an option to
purchase up to 19.9% of the outstanding shares of Company common stock, which
option is exercisable upon the occurrence of certain events specified in the
Stock Option Agreement.

               A copy of the Merger Agreement and a copy of the Stock Option
Agreement are included in this report as Exhibit 2.1 and 2.2, respectively. The
foregoing description is qualified in its entirety by reference to the full text
of such exhibits. A joint press release announcing these transactions is
attached to this report as Exhibit 99.1. The Merger is subject to various
conditions, including clearance under the Hart-Scott-Rodino Antitrust
Improvements Act and approval of the Company's and At Home's stockholders.

         NOW, THEREFORE, in consideration of the covenants, promises and
representations set forth herein, and for other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, the parties agree
as follows:

                                    ARTICLE I

         1.1 The Merger. At the Effective Time (as defined in Section 1.2) and
subject to and upon the terms and conditions of this Agreement and the
applicable provisions of Delaware Law, Merger Sub shall be merged with and into
the Company (the "MERGER"), the separate corporate existence of Merger Sub shall
cease and the Company shall continue as the surviving corporation. The Company
as the surviving corporation after the Merger is hereinafter sometimes referred
to as the "SURVIVING CORPORATION".

         1.2 Effective Time; Closing. Subject to the provisions of this
Agreement, the parties hereto shall cause the Merger to be consummated by filing

accordance with the relevant provisions of Delaware Law (the "CERTIFICATE OF
MERGER") (the time of such filing with the Secretary of State of the State of
Delaware (or such later time as may be agreed in writing by the Company and
Parent and specified in the Certificate of Merger) being the "EFFECTIVE TIME")
as soon as practicable on or after the Closing Date (as herein defined). Unless
the context otherwise requires, the term "AGREEMENT" as used herein refers
collectively to this Agreement and Plan of Reorganization and the Certificate of
Merger. The closing of the Merger (the "CLOSING") shall take place at the
offices of Wilson Sonsini Goodrich & Rosati, Professional Corporation, at a time
and date to be specified by the parties, which shall be no later than the second
business day after the satisfaction or waiver of the conditions set forth in
Article VI, or at such other time, date and location as the parties hereto agree
in writing (the "CLOSING DATE").

         1.3 Effect of the Merger. At the Effective Time, the effect of the
Merger shall be as provided in this Agreement and the applicable provisions of
Delaware Law. Without limiting the generality of the foregoing, and subject
thereto, at the Effective Time all the property, rights, privileges, powers and
franchises of the Company and Merger Sub shall vest in the Surviving
Corporation, and all debts, liabilities and duties of the Company and Merger Sub
shall become the debts, liabilities and duties of the Surviving Corporation.

         1.4      Certificate of Incorporation; Bylaws.

                  (a) At the Effective Time, the Certificate of Incorporation of
Merger Sub, as in effect immediately prior to the Effective Time, shall be the
Certificate of Incorporation of the Surviving Corporation until thereafter
amended as provided by law and such Certificate of Incorporation of the
Surviving Corporation; provided, however, that at the Effective Time the


<PAGE>   3

Certificate of Incorporation of the Surviving Corporation shall be amended so
that the name of the Surviving Corporation shall be "Excite, Inc.".

                  (b) The Bylaws of Merger Sub, as in effect immediately prior
to the Effective Time, shall be, at the Effective Time, the Bylaws of the
Surviving Corporation until thereafter amended.

         1.5 Directors and Officers. The initial directors of the Surviving
Corporation shall be the directors of Merger Sub immediately prior to the
Effective Time, until their respective successors are duly elected or appointed
and qualified. The initial officers of the Surviving Corporation shall be the
officers of Merger Sub immediately prior to the Effective Time, until their
respective successors are duly appointed.

         1.6 Effect on Capital Stock. Subject to the terms and conditions of
this Agreement, at the Effective Time, by virtue of the Merger and without any
action on the part of Merger Sub, the Company or the holders of any of the
following securities, the following shall occur:

                  (a)      Conversion of Company Capital Stock.

                           (i) Company Common Stock. Each share of Common Stock,
par value $0.001 per share, of the Company (including the associated Rights (as
defined in that certain Rights Agreement (the "COMPANY RIGHTS PLAN") dated as of
October 15, 1998 between the Company and BankBoston, N.A., as Rights Agent)
("COMPANY COMMON STOCK") issued and outstanding immediately prior to the
Effective Time, other than any shares of the Company Common Stock to be canceled
pursuant to Section 1.6(b), will be canceled and extinguished and automatically
converted (subject to Section 1.6(e)) into the right to receive 1.041902 shares
(the "EXCHANGE RATIO") of the Series A Common Stock, par value $0.01 per share,
of Parent ("PARENT COMMON STOCK") upon surrender of the certificate representing
such share of Company Common Stock in the manner provided in Section 1.7 (or in
the case of a lost, stolen or destroyed certificate, upon delivery of an
affidavit (and bond, if required) in the manner provided in Section 1.9). If any
shares of Company Common Stock outstanding immediately prior to the Effective
Time are unvested or are subject to a repurchase option, risk of forfeiture or
other condition under any applicable restricted stock purchase agreement or
other agreement with the Company, then the shares of Parent Common Stock issued
in exchange for such shares of Company Common Stock will also be unvested and
subject to the same repurchase option, risk of forfeiture or other condition,
and the certificates representing such shares of Parent Common Stock may
accordingly be marked with appropriate legends. The Company shall take all
action that may be necessary to ensure that, from and after the Effective Time,
Parent is entitled to exercise any such repurchase option or other right set
forth in any such restricted stock purchase agreement or other agreement.

                           (ii) Company Preferred Stock. Each share of Series
E-3 Preferred Stock, par value $0.001 per share, of the Company (including the
associated Rights (as defined in the Company Rights Plan), if any) ("COMPANY
PREFERRED STOCK" and, together with Company Common 


<PAGE>   4

Stock, "COMPANY CAPITAL STOCK") issued and outstanding immediately prior to the
Effective Time, other than any shares of the Company Preferred Stock to be
canceled pursuant to Section 1.6(b), will be canceled and extinguished and
automatically converted (subject to Section 1.6(e)) into the right to receive a
number of shares of Parent Common Stock equal to the Exchange Ratio multiplied
by the number of shares of Company Common Stock issuable upon conversion of one
share of Company Preferred Stock, upon surrender of the certificate representing
such share of Company Preferred Stock in the manner provided in Section 1.7 (or
in the case of a lost, stolen or destroyed certificate, upon delivery of an
affidavit (and bond, if required) in the manner provided in Section 1.9). If any
shares of Company Preferred Stock outstanding immediately prior to the Effective
Time are unvested or are subject to a repurchase option, risk of forfeiture or
other condition under any applicable restricted stock purchase agreement or
other agreement with the Company, then the shares of Parent Common Stock issued
in exchange for such shares of Company Preferred Stock will also be unvested and
subject to the same repurchase option, risk of forfeiture or other condition,
and the certificates representing such shares of Parent Common Stock may
accordingly be marked with appropriate legends. The Company shall take all
action that may be necessary to ensure that, from and after the Effective Time,
Parent is entitled to exercise any such repurchase option or other right set
forth in any such restricted stock purchase agreement or other agreement.

                  (b) Cancellation of Parent-Owned Stock. Each share of Company
Capital Stock held by the Company or owned by Merger Sub, Parent or any direct
or indirect wholly-owned subsidiary of the Company or of Parent immediately
prior to the Effective Time shall be canceled and extinguished without any
conversion thereof.

                  (c) Stock Options; Employee Stock Purchase Plans. At the
Effective Time, all options to purchase Company Common Stock then outstanding
under the Company's 1995 Equity Incentive Plan, the Company's 1996 Equity
Incentive Plan, as amended, the Company's 1996 Directors Stock Option Plan, the
Netbot, Inc. 1996 Stock Option Plan, the MatchLogic, Inc. 1997 Equity
Compensation Plan, the MatchLogic, Inc. 1996 Stock Option Plan, the Throw, Inc.
1996 Option Plan and the Classifieds 2000, Inc. 1996 Stock Option Plan
(collectively, the "COMPANY STOCK OPTION PLANS") shall be assumed by Parent in
accordance with Section 5.9 hereof. Rights outstanding under the Company's 1996
Employee Stock Purchase Plan (the "COMPANY PURCHASE PLAN") shall be treated as
set forth in Section 5.9 hereof.

                  (d) Capital Stock of Merger Sub. Each share of Common Stock of
Merger Sub (the "MERGER SUB COMMON STOCK") issued and outstanding immediately
prior to the Effective Time shall be converted into one validly issued, fully
paid and nonassessable share of Common Stock of the Surviving Corporation. Each
certificate evidencing ownership of shares of Merger Sub Common Stock shall
evidence ownership of such shares of capital stock of the Surviving Corporation.

                  (e) Fractional Shares. No fraction of a share of Parent Common
Stock will be issued by virtue of the Merger, but in lieu thereof each holder of
shares of Company Capital Stock who would otherwise be entitled to a fraction of
a share of Parent Common Stock (after aggregating all fractional shares of
Parent Common Stock that otherwise would be received by such holder) shall,


<PAGE>   5

upon surrender of such holder's Certificate(s) (as defined in Section 1.7(c)),
receive from Parent an amount of cash (rounded to the nearest whole cent),
without interest, equal to the product of (i) such fraction, multiplied by (ii)
the average closing price of one share of Parent Common Stock for the ten (10)
most recent days that Parent Common Stock has traded ending on the trading day
ending one day prior to the Closing Date, as reported on the Nasdaq National
Market System ("NASDAQ").

                  (f) Adjustments to Exchange Ratio. The Exchange Ratio shall be
adjusted to reflect fully the appropriate effect of any stock split, reverse
stock split, stock dividend (including any dividend or distribution of
securities convertible into Parent Common Stock or Company Capital Stock),
reorganization, recapitalization, reclassification or other like change with
respect to Parent Common Stock or Company Capital Stock occurring on or after
the date hereof and prior to the Effective Time.

         1.7      Surrender of Certificates.

                  (a) Exchange Agent. Parent shall select an institution
reasonably satisfactory to the Company to act as the exchange agent (the
"EXCHANGE AGENT") in the Merger.

                  (b) Parent to Provide Common Stock. Promptly after the
Effective Time, Parent shall make available to the Exchange Agent for exchange
in accordance with this Article I, the shares of Parent Common Stock issuable
pursuant to Section 1.6 in exchange for outstanding shares of Company Capital
Stock, and cash in an amount sufficient for payment in lieu of fractional shares
pursuant to Section 1.6(e) and any dividends or distributions which holders of
shares of Company Capital Stock may be entitled pursuant to Section 1.7(d).

                  (c) Exchange Procedures. Promptly after the Effective Time,
Parent shall cause the Exchange Agent to mail to each holder of record (as of
the Effective Time) of a certificate or certificates (the "CERTIFICATES") which
immediately prior to the Effective Time represented outstanding shares of
Company Capital Stock whose shares were converted into the right to receive
shares of Parent Common Stock pursuant to Section 1.6, cash in lieu of any
fractional shares pursuant to Section 1.6(f) and any dividends or other
distributions pursuant to Section 1.7(d), (i) a letter of transmittal (which
shall specify that delivery shall be effected, and risk of loss and title to the
Certificates shall pass, only upon delivery of the Certificates to the Exchange
Agent and shall be in such form and have such other provisions as Parent may
reasonably specify) and (ii) instructions for use in effecting the surrender of
the Certificates in exchange for certificates representing shares of Parent
Common Stock, cash in lieu of any fractional shares pursuant to Section 1.6(e)
and any dividends or other distributions pursuant to Section 1.7(d). Upon
surrender of Certificates for cancellation to the Exchange Agent or to such
other agent or agents as may be appointed by Parent, together with such letter
of transmittal, duly completed and validly executed in accordance with the
instructions thereto, the holders of such Certificates shall be entitled to
receive in exchange therefor certificates representing the number of whole
shares of Parent Common Stock, payment in lieu of fractional shares which such
holders have the right to receive pursuant to Section 1.6(e) and any


<PAGE>   6

dividends or distributions payable pursuant to Section 1.7(d), and the
Certificates so surrendered shall forthwith be canceled. Until so surrendered,
outstanding Certificates will be deemed from and after the Effective Time, for
all corporate purposes, subject to Section 1.7(d) as to the payment of
dividends, to evidence the ownership of the number of full shares of Parent
Common Stock into which such shares of Company Capital Stock shall have been so
converted and the right to receive an amount in cash in lieu of the issuance of
any fractional shares in accordance with Section 1.6(e) and any dividends or
distributions payable pursuant to Section 1.7(d).

                  (d) Distributions With Respect to Unexchanged Shares. No
dividends or other distributions declared or made after the date of this
Agreement with respect to Parent Common Stock with a record date after the
Effective Time will be paid to the holders of any unsurrendered Certificates
with respect to the shares of Parent Common Stock represented thereby until the
holders of record of such Certificates shall surrender such Certificates.
Subject to applicable law, following surrender of any such Certificates, the
Exchange Agent shall deliver to the record holders thereof, without interest,
certificates representing whole shares of Parent Common Stock issued in exchange
therefor along with payment in lieu of fractional shares pursuant to Section
1.6(e) hereof and the amount of any such dividends or other distributions with a
record date after the Effective Time payable with respect to such whole shares
of Parent Common Stock.

                  (e) Transfers of Ownership. If certificates for shares of
Parent Common Stock are to be issued in a name other than that in which the
Certificates surrendered in exchange therefor are registered, it will be a
condition of the issuance thereof that the Certificates so surrendered will be
properly endorsed and otherwise in proper form for transfer and that the persons
requesting such exchange will have paid to Parent or any agent designated by it
any transfer or other taxes required by reason of the issuance of certificates
for shares of Parent Common Stock in any name other than that of the registered
holder of the Certificates surrendered, or established to the satisfaction of
Parent or any agent designated by it that such tax has been paid or is not
payable.

                  (f) Required Withholding. Each of the Exchange Agent, Parent
and the Surviving Corporation shall be entitled to deduct and withhold from any
consideration payable or otherwise deliverable pursuant to this Agreement to any
holder or former holder of Company Capital Stock such amounts as may be required
to be deducted or withheld therefrom under the Code or under any provision of
state, local or foreign tax law or under any other applicable Legal Requirement
(as defined in Section 3.10). To the extent such amounts are so deducted or
withheld, such amounts shall be treated for all purposes under this Agreement as
having been paid to the person to whom such amounts would otherwise have been
paid.

                  (g) No Liability. Notwithstanding anything to the contrary in
this Section 1.7, neither the Exchange Agent, Parent, the Surviving Corporation
nor any party hereto shall be liable to a holder of shares of Parent Common
Stock or Company Capital Stock for any amount properly paid to a public official
pursuant to any applicable abandoned property, escheat or similar law.

         1.8 No Further Ownership Rights in Company Capital Stock. All shares of
Parent 


<PAGE>   7

Common Stock issued upon the surrender for exchange of shares of Company Capital
Stock in accordance with the terms hereof (including any cash paid in respect
thereof pursuant to Section 1.6(f) and 1.7(d)) shall be deemed to have been
issued in full satisfaction of all rights pertaining to such shares of Company
Capital Stock, and there shall be no further registration of transfers on the
records of the Surviving Corporation of shares of Company Capital Stock which
were outstanding immediately prior to the Effective Time. If after the Effective
Time Certificates are presented to the Surviving Corporation for any reason,
they shall be canceled and exchanged as provided in this Article I.

         1.9 Lost, Stolen or Destroyed Certificates. In the event any
Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall
issue in exchange for such lost, stolen or destroyed Certificates, upon the
making of an affidavit of that fact by the holder thereof, such shares of Parent
Common Stock, cash for fractional shares, if any, as may be required pursuant to
Section 1.6(e) and any dividends or distributions payable pursuant to Section
1.7(d); provided, however, that Parent may, in its discretion and as a condition
precedent to the issuance thereof, require the owner of such lost, stolen or
destroyed Certificates to deliver a bond in such sum as it may reasonably direct
as indemnity against any claim that may be made against Parent, the Company or
the Exchange Agent with respect to the Certificates alleged to have been lost,
stolen or destroyed.

         1.10 Tax Consequences. It is intended by the parties hereto that the
Merger shall constitute a reorganization within the meaning of Section 368 of
the Code. The parties hereto adopt this Agreement as a "plan of reorganization"
within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the United States
Income Tax Regulations.

         1.11 Taking of Necessary Action; Further Action. If, at any time after
the Effective Time, any further action is necessary or desirable to carry out
the purposes of this Agreement and to vest the Surviving Corporation with full
right, title and possession to all assets, property, rights, privileges, powers
and franchises of the Company and Merger Sub, the officers and directors of the
Company and Merger Sub will take all such lawful and necessary action, so long
as such action is consistent with this Agreement. Parent shall cause Merger Sub
to perform fully all of its obligations relating to this Agreement and the
transactions contemplated hereby.

                                   ARTICLE II
                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

         As of the date hereof and as of the Closing Date, the Company
represents and warrants to Parent and Merger Sub, subject to the exceptions

contract, subcontract, lease, binding understanding, instrument, note, option,
warranty, purchase order, license, sublicense, insurance policy, benefit plan or

it may become obligated to make, any future investment in or capital
contribution to any other entity. Neither the Company, nor any subsidiary
thereof, has, at any time, been a general partner of any general partnership,
limited partnership or other entity.

                  (b) The Company and each of its subsidiaries is a corporation
duly organized, validly existing and in good standing under the laws of the
jurisdiction of its incorporation and has all necessary corporate power and
authority: (i) to conduct its business in the manner in which its business is
currently being conducted; (ii) to own and use its assets in the manner in which
its assets are currently owned and used; and (iii) to perform its obligations
under all Contracts by which it is bound.

                  (c) The Company and each of its subsidiaries is qualified to
do business as a foreign corporation, and is in good standing, under the laws of
all jurisdictions where the nature of its business requires such qualification

                  (d) The Company has delivered or made available to Parent a
true and correct copy of the Certificate of Incorporation (including any
Certificate of Designations) and Bylaws of the Company and similar governing
instruments of each of its subsidiaries, each as amended to date (collectively,

effect. The Company is not in violation of any of the provisions of the Company
Charter Documents. None of the Company's subsidiaries is in violation of any

aggregate of $5.0 million principal amount of convertible promissory notes are
outstanding, which are convertible into shares of Company Common Stock based on
the market price of the Company Common Stock. All of the outstanding shares of
capital stock of the Company have been duly authorized and validly issued, and
are fully paid and nonassessable. As of the date of this Agreement, there are no
shares of Company Common Stock held in treasury by the Company. Upon
consummation of the Merger, (A) the shares of Parent Common Stock issued in
exchange for any shares of Company Common Stock that are subject to a Contract
pursuant to which the Company has the right to repurchase, redeem or otherwise
reacquire any shares of Company Common Stock will, without any further act of
Parent, the Company or any other person, become subject to the restrictions,
conditions and other provisions contained in such Contract, and (B) Parent will
automatically succeed to and become entitled to exercise the Company's rights
and remedies under any such Contract.

                  (b) As of the date of this Agreement: (i) 10,967,436 shares of

price of $224,746,618; and (ii) 680,665 shares of Company Common Stock are
reserved for future issuance under the Company Purchase Plan. (Stock options

the exercise price of such Company Option; (v) the date on which such Company
Option was granted or assumed; (vi) the date on which such Company Option
expires and (vii) whether the exercisability of such option will be accelerated
in any way by the transactions contemplated by this Agreement, and indicates the
extent of acceleration. The Company has made available to Parent accurate and
complete copies of all stock option plans pursuant to which the Company has

option agreements evidencing such options and the applicable vesting schedule
for each such option. All shares of Company Common Stock subject to issuance as
aforesaid, upon issuance on the terms and conditions specified in the
instruments pursuant to which they are issuable, would be duly authorized,
validly issued, fully paid and nonassessable. Except as set forth in Part
2.2(b)(i) of the Company Schedules, there are no commitments or agreements of

the vesting of any Company Option as a result of the Merger.

Agreement and except for the Company Rights Plan, there are no registration

         2.4      Authority; Non-Contravention.

                  (a) The Company has all requisite corporate power and
authority to enter into this Agreement and the Stock Option Agreement and to
consummate the transactions contemplated hereby and thereby. The execution and
delivery of this Agreement and the Stock Option Agreement and the consummation
of the transactions contemplated hereby and thereby have been duly authorized by
all necessary corporate action on the part of the Company, subject only to the
approval and adoption of this Agreement and the approval of the Merger by the
Company's stockholders and the filing of the Certificate of Merger pursuant to
Delaware Law. A vote of the holders of a majority of the outstanding shares of
the Company Common Stock is sufficient for the Company's stockholders to approve
and adopt this Agreement and approve the Merger. This Agreement and the Stock
Option Agreement have each been duly executed and delivered by the Company and,
assuming due execution and delivery by Parent and Merger Sub, constitute valid
and binding obligations of the Company, enforceable against the Company in
accordance with their terms, except as enforceability may be limited by
bankruptcy and other similar laws and general principles of equity. The
execution and delivery of this Agreement and the Stock Option Agreement by the
Company do not, and the performance of this Agreement and the Stock Option
Agreement by the Company will not, (i) conflict with or violate the Company
Charter Documents, (ii) subject to obtaining the approval and adoption of this
Agreement and the approval of the Merger by the Company's stockholders as
contemplated in Section 5.2 and compliance with the requirements set forth in
Section 2.4(b) below, conflict with or violate any law, rule, regulation, order,
judgment or decree applicable to the Company or any of its subsidiaries or by
which the Company or any of its subsidiaries or any of their respective
properties is bound or affected, or (iii) result in any material breach of or
constitute a material default (or an event that with notice or lapse of time or
both would become a material default) under, or impair the Company's rights or
alter the rights or obligations of any third party under, or give to others any
rights of termination, amendment, acceleration or cancellation of, or result in
the creation of a material Encumbrance on any of the material properties or
assets of the Company or any of its subsidiaries pursuant to, any material note,
bond, mortgage, indenture, contract, agreement, lease, license, permit,
franchise, concession, or other instrument or obligation to which the Company or
any of its subsidiaries is a party or by which the Company or any of its
subsidiaries or its or any of their respective assets are bound or affected. The
terms of this Agreement, including without limitation, the provisions of Article
I and Section 5.9 hereof, do not conflict with or violate the Company Charter
Documents or conflict with or violate or impair the Company's rights or alter
the rights (other than changes in the securities subject thereto from shares of
Company Capital Stock to shares of Parent Common Stock and corresponding
appropriate adjustments to per share conversion or exercise prices thereunder in
accordance with the terms of this Agreement) or obligations of any third party
under any instrument or agreement to which the Company is a party or by which it
is bound relating to the issuance of any securities of the Company, 


<PAGE>   12

including without limitation, any options, warrants or Company Preferred Stock,
and, subject to obtaining the approval and adoption of this Agreement and the
approval of the Merger by the Company's stockholders as aforesaid, the
effectuation of the transactions contemplated by Article I and Section 5.9

Company. As of the date hereof, each share of Company Preferred Stock is
convertible into one share of Company Common Stock. Part 2.4(b) of the Company
Schedules lists all consents, waivers and approvals under any of the Company's
or any of its subsidiaries' agreements, contracts, licenses or leases required

Surviving Corporation as a result of the Merger.

registration, declaration or filing with any court, administrative agency or

Company in connection with the execution and delivery of this Agreement and the

amended (the "EXCHANGE ACT") and the effectiveness of the Registration Statement
(as defined in Section 2.18), (iii) such consents, approvals, orders,
authorizations, registrations, declarations and filings as may be required under
applicable federal, foreign and state securities (or related) laws and the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR
ACT"), and the securities or antitrust laws of any foreign country, and (iv)
such other consents, authorizations, filings, approvals and registrations which

material adverse effect on the ability of the parties hereto to consummate the
Merger.

offer or sell any of its products or services in the present manner or style
thereof. As of the date hereof, to the knowledge of the Company, no event has

does not occur by reason of the execution of this Agreement or the Stock Option
Agreement, the consummation of the Merger, or the consummation of the
transactions contemplated hereby or thereby, and such amendment may not be
further amended by Company without the prior consent of Parent in its sole
discretion.

         3.4      Authority; Non-Contravention.

                  (a) Parent has all requisite corporate power and authority to
enter into this Agreement and to consummate the transactions contemplated
hereby. The execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby have been duly authorized by all necessary
corporate action on the part of Parent and Merger Sub (including, in the case of
Merger Sub, all shareholder action by Parent as its sole stockholder), subject
only to the approval of the issuance of the shares of Parent Common Stock
pursuant to the Merger and approval of an amendment to Parent's Certificate of
Incorporation to increase the authorized number of shares of Parent Common Stock
so as to permit the transactions contemplated hereby, subject to and upon
consummation of the Merger, and the filing of the Certificate of Merger pursuant
to Delaware Law. The vote in favor of such issuance and an amendment to Parent's
Certificate of Incorporation by TCI Internet Holdings, Inc. ("TCI") is currently
sufficient, and, to the extent TCI shall not have breached the Parent Voting
Agreement to which it is a party and to the extent such Parent Voting Agreement
shall not have terminated by its terms, will be sufficient at the time of the
Parent Stockholders Meeting, for Parent's stockholders to approve such issuance
and amendment. This Agreement has been duly executed and delivered by Parent and
Merger Sub, and assuming due execution and delivery by the Company, constitute a
valid and binding obligation of Parent and Merger Sub, enforceable against
Parent and Merger Sub in accordance with their respective terms, except as
enforceability may be limited by bankruptcy and other similar laws and general
principles of equity. The execution and delivery of this Agreement by Parent and
Merger Sub do not, and the performance of this Agreement by Parent and Merger
Sub will not, (i) subject to the approval of an amendment to Parent's
Certificate of Incorporation to appropriately increase the authorized number of
shares of Parent Common Stock, conflict with the Parent Charter Documents, (ii)
subject to obtaining the approval by Parent's stockholders of the issuance of
the shares of Parent Common Stock pursuant to the Merger and an amendment to
Parent's Certificate of Incorporation to appropriately increase the authorized
number of shares of Parent Common Stock as contemplated in Section 5.3 and
compliance with the requirements set forth in Section 3.4(b) below, conflict
with or violate any law, rule, regulation, order, judgment or decree applicable
to Parent or any of its subsidiaries or by which Parent or any of its
subsidiaries or any of their respective properties are bound or affected, or
(iii) result in any material breach of or constitute a material default (or an
event that with notice or lapse of time or both would become a material default)
under, or impair Parent's rights or alter the rights or obligations of any third
party under, or give to others any rights of termination, amendment,
acceleration or cancellation of, or result in the creation of a material
Encumbrance on any of the material properties or assets of Parent or any of its
subsidiaries pursuant to, any material note, bond, mortgage, indenture,
contract, agreement, lease, license, permit, franchise, concession, or other
instrument or obligation to which Parent or any of its subsidiaries is a party
or by which Parent or any of its subsidiaries or its or any of their respective
assets are bound or affected. Merger Sub was formed for the purpose of
consummating the Merger and has no material assets or liabilities. Part 2.4(a)
of the Parent Schedules lists all consents, waivers and approvals under any of
the Company's or any of its subsidiaries' agreements, contracts, licenses or
leases required to be obtained in connection with the consummation of the
transactions contemplated 


<PAGE>   32

hereby, which, if individually or in the aggregate not obtained, would result in
a material loss of benefits to Parent as a result of the Merger.

                  (b) No consent, approval, order or authorization of, or
registration, declaration or filing with any Governmental Entity, is required to
be obtained or made by Parent or Merger Sub in connection with the execution and
delivery of this Agreement or the consummation of the Merger, except for (i) the
filing of the Certificate of Merger with the Secretary of State of the State of
Delaware, (ii) the filing of an amendment to Parent's Certificate of
Incorporation to increase the authorized number of shares of Parent Common Stock
so as to permit the transactions contemplated hereby, (iii) the filing of the
Registration Statement and the Prospectus/Proxy Statement and a Schedule 13D
with regard to the Company Voting Agreements and the Stock Option Agreement in
accordance with the Securities Act and the Exchange Act, as the case may be, and
the effectiveness of the Registration Statement, (iv) such consents, approvals,
orders, authorizations, registrations, declarations and filings as may be
required under applicable federal, foreign and state securities (or related)
laws and the HSR Act, and the securities or antitrust laws of any foreign
country, and (v) such other consents, authorizations, filings, approvals and
registrations which if not obtained or made would not be material to Parent or
have a material adverse effect on the ability of the parties hereto to
consummate the Merger.

hereof until the Closing, (i) complied as to form in all material respects with
the published rules and regulations of the SEC with respect thereto, (ii) was
prepared in accordance with GAAP applied on a consistent basis throughout the

correct copy of any amendments or modifications, which have not yet been filed
with the SEC but which are required to be filed, to agreements, documents or

          3.6 Absence of Certain Changes or Events. Since the date of Parent
Balance Sheet there has not been: (i) any Material Adverse Effect on Parent,
(ii) any declaration, setting aside or payment of any dividend on, or other
distribution (whether in cash, stock or property) in respect of, any of Parent's

legal right of Parent to design, manufacture, offer or sell any of its products
or services in the present manner or style thereof. As of the date hereof, to
the knowledge of Parent, no event has occurred, and no claim, dispute or other

in such a manner as would permit any other party to cancel or terminate any such
material Contract of Parent, or would permit any other party to seek material

defaults, in the aggregate). Parent has made available to the Company for its
inspection all material Contracts of Parent.

Merger and/or this Agreement.

                  (b) Subject to Section 5.2(c): (i) the Board of Directors of
the Company shall unanimously recommend that the Company's stockholders vote in
favor of and adopt and approve this Agreement and approve the Merger at the
Company Stockholders' Meeting; (ii) the Prospectus/Proxy Statement shall include
a statement to the effect that the Board of Directors of the Company has
unanimously recommended that the Company's stockholders vote in favor of and
adopt and approve this Agreement and the Merger at the Company Stockholders'
Meeting; and (iii) neither the Board of Directors of the Company nor any
committee thereof shall withdraw, amend or modify, or propose or resolve to
withdraw, amend or modify in a manner adverse to Parent, the unanimous
recommendation of the Board of Directors of the Company that the Company's
stockholders vote in favor of and adopt and approve this Agreement and the
Merger. For purposes of this Agreement, said recommendation of the Board of
Directors shall be deemed to have been modified in a manner adverse to Parent if
said recommendation shall no longer be unanimous, provided that, for all
purposes of this Agreement, an action by any Board of Directors or committee
thereof shall be unanimous if each member of such Board of Directors or
committee has approved such action other than (i) any such member who has
appropriately abstained from voting on such matter because of an actual or
potential conflict of interest and (ii) any such member who is unable to vote in
connection with such action as a result of death or disability.

                  (c) Nothing in this Agreement shall prevent the Board of
Directors of the Company from withholding, withdrawing, amending or modifying
its unanimous recommendation in favor of the Merger if (i) a Superior Offer (as
defined below) is made to the Company and is not withdrawn, (ii) the Company
shall have provided written notice to Parent (a "NOTICE OF SUPERIOR OFFER")
advising Parent that the Company has received a Superior Offer, specifying the
material terms and conditions of such Superior Offer and identifying the person
or entity making such Superior Offer, (iii) Parent shall not have, within five
(5) business days of Parent's receipt of the Notice of Superior Proposal, made
an offer that the Company Board by a majority vote determines in its good faith
judgment (based on the written advice of its financial adviser) to be at least
as favorable to the Company's stockholders as such Superior Proposal (it being
agreed that the Company Board shall convene a meeting to consider any such offer
by Parent promptly following the receipt thereof), (iv) the Board of Directors
of the Company concludes in good faith, after consultation with its outside
counsel, that, in light of such Superior Offer, the withholding, withdrawal,
amendment or modification of such recommendation is required in order for the
Board of Directors of the Company to comply with its fiduciary obligations to
the Company's stockholders under applicable law and (v) the Company shall not
have violated any of the restrictions set forth in 


<PAGE>   47

Section 5.5 or this Section 5.2. The Company shall provide Parent with at least
three business days prior notice (or such lesser prior notice as provided to the
members of the Company's Board of Directors but in no event less than
twenty-four hours) of any meeting of the Company's Board of Directors at which
the Company's Board of Directors is reasonably expected to consider any
Acquisition Transaction (as defined below). Subject to applicable laws, nothing
contained in this Section 5.2 shall limit the Company's obligation to hold and
convene the Company Stockholders' Meeting (regardless of whether the unanimous
recommendation of the Board of Directors of the Company shall have been
withdrawn, amended or modified). For purposes of this Agreement "SUPERIOR OFFER"
shall mean an unsolicited, bona fide written offer made by a third party to
consummate any of the following transactions: (i) a merger or consolidation
involving the Company pursuant to which the stockholders of the Company
immediately preceding such transaction hold less than 40% of the equity interest
in the surviving or resulting entity of such transaction or (ii) the acquisition
by any person or group (including by way of a tender offer or an exchange offer
or a two step transaction involving a tender offer followed with reasonable
promptness by a cash-out merger involving the Company), directly or indirectly,
of ownership of 100% of the then outstanding shares of capital stock of the
Company, on terms that the Board of Directors of the Company determines, in its
reasonable judgment (based on the written advice of its financial adviser) to be
more favorable to the Company stockholders than the terms of the Merger;
provided, however, that any such offer shall not be deemed to be a "Superior
Offer" if any financing required to consummate the transaction contemplated by
such offer is not committed and is not likely in the reasonable judgment of the
Company's Board of Directors (based on the advice of its financial adviser) to
be obtained by such third party on a timely basis.

                  (d) Nothing contained in this Agreement shall prohibit the
Company or its Board of Directors from taking and disclosing to its stockholders
a position contemplated by Rules 14d-9 and 14e-2(a) promulgated under the
Exchange Act.

         5.3      Meeting of Parent Stockholders.

                  (a) Promptly after the date hereof, Parent will take all
action necessary in accordance with the Delaware Law and its Certificate of
Incorporation and Bylaws to convene a meeting of Parent's stockholders to
consider the issuance of the shares of Parent Common Stock pursuant to the
Merger and an amendment to Parent's Certificate of Incorporation to increase the
authorized number of shares of Parent Common Stock so as to permit the
transactions contemplated hereby, subject to and upon consummation of the
Merger, (the "PARENT STOCKHOLDERS MEETING") to be held as promptly as
practicable, and in any event (to the extent permissible under applicable law)
within 45 days after the declaration of effectiveness of the Registration
Statement. Parent will use its commercially reasonable efforts to solicit from
its stockholders proxies in favor of the issuance of the shares of Parent Common
Stock pursuant to the Merger and an amendment to Parent's Certificate of
Incorporation to increase the authorized number of shares of Parent Common Stock
so as to permit the transactions contemplated hereby, subject to and upon
consummation of the Merger, and will take all other action necessary or
advisable to secure the vote or consent of its 


<PAGE>   48

stockholders required by the rules of Nasdaq or Delaware Law to obtain such
approvals. Notwithstanding anything to the contrary contained in this Agreement,
Parent may adjourn or postpone the Parent Stockholders' Meeting to the extent
necessary to ensure that any necessary supplement or amendment to the
Prospectus/Proxy Statement is provided to Parent's stockholders in advance of a
vote on the issuance of the shares of Parent Common Stock pursuant to the Merger
or a vote on the approval of an amendment to Parent's Certificate of
Incorporation to increase the authorized number of shares of Parent Common Stock
so as to permit the transactions contemplated hereby, subject to and upon
consummation of the Merger, or, if as of the time for which Parent Stockholders'
Meeting is originally scheduled (as set forth in the Prospectus/Proxy Statement)
there are insufficient shares of Parent Common Stock represented (either in
person or by proxy) to constitute a quorum necessary to conduct the business of
the Parent's Stockholders' Meeting. Parent shall ensure that the Parent
Stockholders' Meeting is called, noticed, convened, held and conducted, that all
proxies solicited by the Company in connection with the Parent Stockholders'
Meeting are solicited in compliance with the Delaware Law, its Certificate of
Incorporation and Bylaws, the rules of Nasdaq and all other applicable legal
requirements.

                  (b) The Board of Directors of Parent shall unanimously
recommend that Parent's stockholders vote in favor of the issuance of the shares
of Parent Common Stock pursuant to the Merger and an amendment to Parent's
Certificate of Incorporation to increase the authorized number of shares of
Parent Common Stock so as to permit the transactions contemplated hereby,
subject to and upon consummation of the Merger. The Prospectus/Proxy Statement
shall include a statement to the effect that the Board of Directors of Parent
has unanimously recommended that Parent's stockholders vote in favor of such
matters at the Parent Stockholders' Meeting. Neither the Board of Directors of
Parent nor any committee thereof shall withdraw, amend or modify, or propose or
resolve to withdraw, amend or modify in a manner adverse to the Company, the
unanimous recommendation of the Board of Directors of Parent that Parent's
stockholders vote in favor of such matters. For purposes of this Agreement, said
recommendation of the Board of Directors shall be deemed to have been modified
in a manner adverse to the Company if said recommendation shall no longer be
unanimous.

                  (c) Nothing contained in this Agreement shall prohibit Parent
or its Board of Directors from taking and disclosing to its stockholders a
position contemplated by Rules 14d-9 and 14e-2(a) promulgated under the Exchange
Act.

         5.4      Confidentiality; Access to Information.

                  (a) The parties acknowledge that the Company and Parent have
previously executed a Confidentiality Agreement dated January 12, 1999 (the
"CONFIDENTIALITY AGREEMENT"), which Confidentiality Agreement will continue in
full force and effect in accordance with its terms.

                  (b) Access to Information. Each of the Company and Parent will
afford the other and the other's accountants, counsel and other representatives
reasonable access during normal 


<PAGE>   49

business hours to its properties, books, records and personnel during the period
prior to the Effective Time to obtain all information concerning its business,
including the status of product development efforts, properties, results of
operations and personnel, as such other party may reasonably request. No
information or knowledge obtained in any investigation pursuant to this Section
5.4 will affect or be deemed to modify any representation or warranty contained
herein or the conditions to the obligations of the parties to consummate the
Merger.

         5.5      No Solicitation.

                  (a) From and after the date of this Agreement until the
Effective Time or termination of this Agreement pursuant to Article VII, the
Company and its subsidiaries will not, nor will they authorize or permit any of
their respective officers, directors, affiliates or employees or any investment
banker, attorney or other advisor or representative retained by any of them to,
directly or indirectly, (i) solicit, initiate, encourage or induce the making,
submission or announcement of any Acquisition Proposal (as hereinafter defined),
(ii) participate in any discussions or negotiations regarding, or furnish to any
person any non-public information with respect to, or take any other action to
facilitate any inquiries or the making of any proposal that constitutes or may
reasonably be expected to lead to, any Acquisition Proposal, (iii) engage in
discussions with any person with respect to any Acquisition Proposal, except as
to the existence of these provisions, (iv) approve, endorse or recommend any
Acquisition Proposal or (v) enter into any letter of intent or similar document
or any contract agreement or commitment contemplating or otherwise relating to
any Acquisition Transaction; provided, however, that after receipt of an
unsolicited, written, bona fide Acquisition Proposal that the Board of Directors
of the Company reasonably concludes may constitute a Superior Offer, the Company
may on one occasion submit to the party making such Acquisition Proposal a
written list of questions, the sole purpose of which is to elicit clarifications
as to the material terms of the Acquisition Proposal so as to enable the Board
of Directors of the Company to make a determination whether such Acquisition
Proposal is in fact a Superior Offer (it being agreed that any correspondence
with such party shall be limited to questions and such questions shall be
limited to the purpose of clarifying the material terms of such Acquisition
Proposal and shall not solicit or encourage any new Acquisition Proposal or any
change to the Acquisition Proposal, and it being further agreed that the Company
shall provide Parent with a copy of any correspondence to be delivered pursuant
to this Section 5.5(a) at least 48 hours prior to sending such correspondence to
any third party). The Company and its subsidiaries will immediately cease any
and all existing activities, discussions or negotiations with any parties
conducted heretofore with respect to any Acquisition Proposal. Without limiting
the foregoing, it is understood that any violation of the restrictions set forth
in the preceding two sentences by any officer, director or employee of the
Company or any of its subsidiaries or any investment banker, attorney or other
advisor or representative of the Company or any of its subsidiaries shall be
deemed to be a breach of this Section 5.5 by the Company.

         For purposes of this Agreement, "ACQUISITION PROPOSAL" shall mean any
offer or proposal (other than an offer or proposal by Parent) relating to any
Acquisition Transaction. For purposes of 


<PAGE>   50

this Agreement, "ACQUISITION TRANSACTION" shall mean any transaction or series
of related transactions involving: (A) any purchase from the Company or
acquisition by any person or "group" (as defined under Section 13(d) of the
Exchange Act and the rules and regulations thereunder) of more than a 5%
interest in the total outstanding voting securities of the Company or any of its
subsidiaries or any tender offer or exchange offer that if consummated would
result in any person or "group" (as defined under Section 13(d) of the Exchange
Act and the rules and regulations thereunder) beneficially owning 5% or more of
the total outstanding voting securities of the Company or any of its
subsidiaries or any merger, consolidation, business combination or similar
transaction involving the Company; (B) any sale, lease (other than in the
ordinary course of business), exchange, transfer, license (other than in the
ordinary course of business), acquisition or disposition of more than 5% of the
assets of the Company; or (C) any liquidation or dissolution of the Company.

                  (b) In addition to the obligations of the Company set forth in
paragraph (a) of this Section 5.5, the Company as promptly as practicable shall
advise Parent orally and in writing of any Acquisition Proposal or any request
for non-public information or inquiry which the Company reasonably believes
would lead to an Acquisition Proposal or to any Acquisition Transaction, the
material terms and conditions of such Acquisition Proposal, request or inquiry,
and the identity of the person or group making any such Acquisition Proposal,
request or inquiry. The Company will keep Parent informed as promptly as
practicable in all material respects of the status and details (including
material amendments or proposed material amendments) of any such Acquisition
Proposal, request or inquiry.

         5.6 Public Disclosure. Without limiting Sections 5.2 or 5.5 hereof or
anything else herein, Parent and the Company will attempt to consult with each
other, and to the extent practicable, agree, before issuing any press release or
otherwise making any public statement with respect to the Merger, this Agreement
or any Acquisition Proposal and will not issue any such press release or make
any such public statement prior to such consultation, except as may be required
by law or any listing agreement with a national securities exchange or Nasdaq.
The parties have agreed to the text of the joint press release announcing the
signing of this Agreement.

         5.7      Reasonable Efforts; Notification.

                  (a) Upon the terms and subject to the conditions set forth in
this Agreement, each of the parties agrees to use all reasonable efforts to
take, or cause to be taken, all actions, and to do, or cause to be done, and to
assist and cooperate with the other parties in doing, all things necessary,
proper or advisable to consummate and make effective, in the most expeditious
manner practicable, the Merger and the other transactions contemplated by this
Agreement, including using reasonable efforts to accomplish the following: (i)
the taking of all reasonable acts necessary to cause the conditions precedent
set forth in Article VI to be satisfied, (ii) the obtaining of all necessary
actions or nonactions, waivers, consents, approvals, orders and authorizations
from Governmental Entities and the making of all necessary registrations,
declarations and filings (including registrations, declarations and filings with
Governmental Entities, if any) and the taking of all reasonable steps as


<PAGE>   51

may be necessary to avoid any suit, claim, action, investigation or proceeding
by any Governmental Entity, (iii) the obtaining of all necessary consents,
approvals or waivers from third parties, (iv) the defending of any suits,
claims, actions, investigations or proceedings, whether judicial or
administrative, challenging this Agreement or the consummation of the
transactions contemplated hereby, including seeking to have any stay or
temporary restraining order entered by any court or other Governmental Entity
vacated or reversed and (v) the execution or delivery of any additional
instruments necessary to consummate the transactions contemplated by, and to
fully carry out the purposes of, this Agreement. In connection with and without
limiting the foregoing, Parent shall not enter into any acquisition which would
be reasonably likely to have the effect of delaying the filing or effectiveness
of the Registration Statement or the filing or mailing of the Prospectus/Proxy
Statement, the holding of either the Company Stockholders' Meeting or Parent
Stockholders' Meeting, or causing the regulatory approvals, consents or
expirations in connection with the Antitrust Filings or Other Filings to be
materially delayed or not obtained. In connection with and without limiting the
foregoing, the Company and its Board of Directors shall, if any state takeover
statute or similar statute or regulation is or becomes applicable to the Merger,
this Agreement or any of the transactions contemplated by this Agreement, use
all reasonable efforts to ensure that the Merger and the other transactions
contemplated by this Agreement may be consummated as promptly as practicable on
the terms contemplated by this Agreement and otherwise to minimize the effect of
such statute or regulation on the Merger, this Agreement and the transactions
contemplated hereby. Notwithstanding anything herein to the contrary, nothing in
this Agreement shall be deemed to require Parent or the Company or any
subsidiary or affiliate thereof to agree to any divestiture by itself or any of
its affiliates of shares of capital stock or of any business, assets or
property, or the imposition of any material limitation on the ability of any of
them to conduct their businesses or to own or exercise control of such assets,
properties and stock.

                  (b) The Company shall give prompt notice to Parent of any
representation or warranty made by it contained in this Agreement becoming
untrue or inaccurate, or any failure of the Company to comply with or satisfy in
any material respect any covenant, condition or agreement to be complied with or
satisfied by it under this Agreement, in each case, such that the conditions set
forth in Section 6.3(a) or 6.3(b) would not be satisfied, provided, however,
that no such notification shall affect the representations, warranties,
covenants or agreements of the parties or the conditions to the obligations of
the parties under this Agreement.

                  (c) Parent shall give prompt notice to the Company of any
representation or warranty made by it or Merger Sub contained in this Agreement
becoming untrue or inaccurate, or any failure of Parent or Merger Sub to comply
with or satisfy in any material respect any covenant, condition or agreement to
be complied with or satisfied by it under this Agreement, in each case, such
that the conditions set forth in Section 6.2(a) or 6.2(b) would not be
satisfied, provided, however, that no such notification shall affect the
representations, warranties, covenants or agreements of the parties or the
conditions to the obligations of the parties under this Agreement.

         5.8 Third Party Consents. As soon as practicable following the date
hereof, Parent and 


<PAGE>   52

the Company will each use its commercially reasonable efforts to obtain any
consents, waivers and approvals under any of its or its subsidiaries' respective
agreements, contracts, licenses or leases required to be obtained in connection
with the consummation of the transactions contemplated hereby.

         5.9      Stock Options and Employee Benefits; Warrants.

                  (a) At the Effective Time, each then outstanding Company
Option, whether or not exercisable at the Effective Time and regardless of the
respective exercise prices thereof, will be assumed by Parent. Each Company
Option so assumed by Parent under this Agreement will continue to have, and be
subject to, the same terms and conditions set forth in the applicable Company
Stock Option Plan (and any applicable stock option agreement for such Company
Option) immediately prior to the Effective Time (including, without limitation,
any repurchase rights or vesting provisions), except that (i) each Company
Option will be exercisable (or will become exercisable in accordance with its
terms) for that number of whole shares of Parent Common Stock equal to the
product of the number of shares of Company Common Stock that were issuable upon
exercise of such Company Option immediately prior to the Effective Time
multiplied by the Exchange Ratio, rounded to the nearest whole number of shares
of Parent Common Stock and (ii) the per share exercise price for the shares of
Parent Common Stock issuable upon exercise of such assumed Company Option will
be equal to the quotient determined by dividing the exercise price per share of
Company Common Stock at which such Company Option was exercisable immediately
prior to the Effective Time by the Exchange Ratio, rounded to the nearest whole
cent. Each assumed Company Option shall be vested immediately following the
Effective Time as to the same percentage of the total number of shares subject
thereto as it was vested as to immediately prior to the Effective Time. As soon
as reasonably practicable, but in no event more than 20 days after the Effective
Time, Parent will issue to each person who holds an assumed Company Option, a
document in form and substance reasonably satisfactory to Company evidencing the
foregoing assumption of such Company Option by Parent.

                  (b) It is intended that Company Options assumed by Parent
shall qualify following the Effective Time as incentive stock options as defined
in Section 422 of the Code to the extent Company Options qualified as incentive
stock options immediately prior to the Effective Time and the provisions of this
Section 5.9 shall be applied consistent with such intent.

                  (c) At the Effective Time, each outstanding purchase right
with respect to all open Offering Periods under the Company Purchase Plan (each
an "ASSUMED PURCHASE RIGHT") shall be assumed by Parent. Each Assumed Purchase
Right shall continue to have, and be subject to, the terms and conditions set
forth in the Company Purchase Plan and the documents governing the Assumed
Purchase Right, except that the purchase price of such shares of Parent Common
Stock for each respective Purchase Date under each Assumed Purchase Right shall
be the lower of (i) the quotient determined by dividing eighty-five percent
(85%) of the fair market value of the Company Common Stock on the Offering Date
of each assumed Offering Period by the Exchange Ratio or (ii)


<PAGE>   53

eighty-five percent (85%) of the fair market value of the Parent Common Stock on
each Purchase Date of each assumed Offering Period occurring after the Effective
Time (with the number of shares rounded down to the nearest whole share and the
purchase price rounded up to the nearest whole cent). The Assumed Purchase
Rights shall be exercised at such times following the Effective Time as set
forth in the Company Purchase Plan, and each participant shall, accordingly, be
issued shares of Parent Common Stock at such times. The Company Purchase Plan
shall terminate with the exercise of the last Assumed Purchase Right, and no
additional purchase rights shall be granted under the Company Purchase Plan
following the Effective Time. Parent agrees that from and after the Effective
Time, employees of the Company may participate in Parent's employee stock
purchase plan, subject to the terms and conditions of such plan. Capitalized
terms in this Section 5.9(c) if not otherwise defined in this Agreement, have
the meanings ascribed to them in the Company Purchase Plan.

                  (d) Prior to the date hereof, the Company shall have granted
stock options pursuant to the Company Stock Option Plans to purchase a number of
shares of Company Common Stock equal in the aggregate to 2,000,000 divided by
the Exchange Ratio (as appropriately adjusted for stock splits and the like) to
such persons and in such amounts as to which Parent shall have agreed, with
strike prices equal to the fair market value of the Company Common Stock at the
time of grant and otherwise with vesting schedules and other terms and
conditions consistent with past practice. Such options shall be granted only to
employees of the Company who, in the good faith judgment of the Company's Board
of Directors, have not previously received options from the Company in a
reasonable and customary amount sufficient to provide adequate incentive to such
employees in connection with their service on behalf of the Company. In
addition, all stock option grants made pursuant to this Section 5.9(d) will
constitute reasonable compensation for personal services to be rendered by the
recipients thereof on or after the Effective Time, and such granted options
shall not exceed the amount of options that would be granted to a similarly
situated employee after the Effective Time.

                  (e) At the Effective Time, each then outstanding warrant to
purchase shares of Company Common Stock or Series E-3 Preferred Stock (each a
"COMPANY WARRANT"), whether or not exercisable, will be assumed by Parent. Each
Company Warrant so assumed by Parent under this Agreement will continue to have,
and be subject to, the same terms and conditions set forth in the applicable
Company Warrant immediately prior to the Effective Time (including, without
limitation, any vesting, expiration or termination provisions), except that (i)
each Company Warrant will be exercisable (or will become exercisable in
accordance with its terms) for that number of whole shares of Parent Common
Stock equal to the product of the number of shares of Company Common Stock or
Series E-3 Preferred Stock that were issuable upon exercise of such Company
Warrant immediately prior to the Effective Time multiplied by the Exchange
Ratio, rounded to the nearest whole number of shares of Parent Common Stock and
(ii) the per share exercise price for the shares of Parent Common Stock issuable
upon exercise of such assumed Company Warrant will be equal to the quotient
determined by dividing the exercise price per share of Company Common Stock or
Series E-3 Preferred Stock at which such Company Warrant was exercisable
immediately prior to the Effective Time by the Exchange Ratio, rounded to the
nearest whole cent. Parent agrees to reserve 


<PAGE>   54

for issuance a sufficient number of shares of Parent Common Stock in respect of
all Company Options and Company Warrants assumed and converted hereunder.

         5.10 Form S-8. Parent agrees to file a registration statement on Form
S-8 for the shares of Parent Common Stock issuable with respect to assumed
Company Options as soon as is reasonably practicable after the Effective Time
and shall maintain the effectiveness of such registration statement thereafter
for so long as any of such options or other rights remain outstanding.

         5.11     Indemnification.

                  (a) From and after the Effective Time, Parent will, and will
cause the Surviving Corporation to, fulfill and honor in all respects the
obligations of the Company pursuant to any indemnification agreements between
the Company and its directors and officers as of the Effective Time (the
"INDEMNIFIED PARTIES"). The Certificate of Incorporation and Bylaws of the
Surviving Corporation will contain provisions with respect to exculpation and
indemnification that are at least as favorable to the Indemnified Parties as
those contained in the Certificate of Incorporation and Bylaws of the Company as
in effect on the date hereof, which provisions will not be amended, repealed or
otherwise modified for a period of six years from the Effective Time in any
manner that would adversely affect the rights thereunder of individuals who,
immediately prior to the Effective Time, were directors, officers, employees or
agents of the Company, unless such modification is required by law.

                  (b) For a period of six years after the Effective Time, Parent
will cause the Surviving Corporation to use its commercially reasonable efforts
to maintain in effect, if available, directors' and officers' liability
insurance covering those persons who are currently covered by the Company's
directors' and officers' liability insurance policy on terms comparable to those
applicable to the current directors and officers of the Company; provided,
however, that in no event will Parent or the Surviving Corporation be required
to expend in excess of 150% of the annual premium currently paid by the Company
for such coverage (or such coverage as is available for such 150% of such annual
premium).

         5.12 Board of Directors of Parent. The Board of Directors of Parent
will take all actions necessary such that one member of the Company's Board of
Directors reasonably acceptable to the Company and Parent shall be appointed to
Parent's Board of Directors (but not as a Series B Common Stock director) with a
term expiring at the next annual meeting of Parent's stockholders and shall
include such person in the slate of nominees recommended by Parent's Board of
Directors to the stockholders of Parent at such annual meeting. In addition, for
a period of one year following the Effective Time, Parent shall give one
additional member of the Company's Board of Directors reasonably acceptable to
the Company and Parent copies of all notices, minutes, consents and other
material that Parent provides to members of its Board of Directors, and shall
permit such person to attend each meeting of Parent's Board of Directors;
provided, however, that (i) Parent reserves the right to exclude such person
from access to any material or meeting or portion thereof if Parent believes
that such exclusion is reasonably necessary to preserve the attorney-client
privilege, to 


<PAGE>   55

protect highly confidential proprietary information or for other similar reasons
and (ii) all obligations of Parent pursuant to this sentence shall be contingent
upon such person executing a non-disclosure agreement satisfactory to Parent.

         5.13 Nasdaq Listing. Prior to the Effective Time, Parent agrees to
authorize for listing on Nasdaq the shares of Parent Common Stock issuable, and
those required to be reserved for issuance, in connection with the Merger, upon
official notice of issuance.

         5.14 Company Affiliates; Restrictive Legend. Parent will give stop
transfer instructions to its transfer agent with respect to any Parent Common
Stock received pursuant to the Merger by any stockholder of the Company who may
reasonably be deemed to be an affiliate of the Company within the meaning of
Rule 145 promulgated under the Securities Act and there will be placed on the
certificates representing such Parent Common Stock, or any substitutions
therefor, a legend stating in substance:

         "THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A
         TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF
         1933, AS AMENDED, APPLIES AND MAY ONLY BE TRANSFERRED (A) IN CONFORMITY
         WITH RULE 145(d) UNDER SUCH ACT, (B) IN ACCORDANCE WITH A WRITTEN
         OPINION OF COUNSEL, REASONABLY ACCEPTABLE TO THE ISSUER IN FORM AND
         SUBSTANCE THAT SUCH TRANSFER IS EXEMPT FROM REGISTRATION UNDER THE
         SECURITIES ACT OF 1933, AS AMENDED.

         5.15 Certain Employee Benefits. As soon as practicable after the
execution of this Agreement, the Company and Parent shall confer and work
together in good faith to agree upon mutually acceptable employee benefit and
compensation arrangements (and terminate Company Employee Plans immediately
prior to the Effective Time if appropriate) so as to provide benefits to Company
employees generally equivalent in the aggregate to those provided to similarly
situated employees of Parent. In addition, the Company agrees that it and its
subsidiaries shall terminate any and all severance, separation, retention and
salary continuation plans, programs or arrangements (other than contractual
agreements disclosed on the Company Schedules) prior to the Effective Time.


                                   ARTICLE VI
                            CONDITIONS TO THE MERGER

         6.1 Conditions to Obligations of Each Party to Effect the Merger. The
respective obligations of each party to this Agreement to effect the Merger
shall be subject to the satisfaction at or prior to the Closing Date of the
following conditions:

                  (a) Company Stockholder Approval. This Agreement shall have
been approved and adopted, and the Merger shall have been duly approved, by the
requisite vote under applicable law, by the stockholders of the Company.



<PAGE>   56

                  (b)      Parent Stockholder Approval.

                           (i) The issuance of the shares of Parent Common Stock
pursuant to the Merger shall have been duly approved by the requisite vote of

Incorporation and other charter documents.

Goodrich & Rosati, Professional Corporation, and Fenwick & West LLP,
respectively), in form and substance reasonably satisfactory to them, to the
effect that the Merger will constitute a tax-free reorganization within the
meaning of Section 368(a) of the Code and such opinions shall not have been
withdrawn; provided, however, that if the counsel to either Parent or the
Company does not render such opinion, this condition shall nonetheless be deemed
to be satisfied with respect to such party if counsel to the other party renders
such opinion to such party. The parties to this Agreement agree to make such
reasonable representations as requested by such counsel for the purpose of
rendering such opinions.

                  (f) Nasdaq Listing. The shares of Parent Common Stock to be
issued in the Merger shall have been authorized for listing on Nasdaq, subject
to notice of issuance.

                        TERMINATION, AMENDMENT AND WAIVER

         7.1 Termination. This Agreement may be terminated at any time prior to
the Effective Time, whether before or after the requisite approvals of the
stockholders of the Company or Parent:

                  (a) by mutual written consent duly authorized by the Boards of
Directors of Parent and the Company;

                  (b) by either the Company or Parent if the Merger shall not
have been consummated by September 30, 1999 (the "END DATE") for any reason;
provided, however, that the right to terminate this Agreement under this Section
7.1(b) shall not be available to any party whose action or failure to act has
been a principal cause of or resulted in the failure of the Merger to occur on
or before such date and such action or failure to act constitutes a material
breach of this Agreement;

                  (c) by either the Company or Parent if a Governmental Entity
shall have issued an order, decree or ruling or taken any other action, in any
case having the effect of permanently restraining, enjoining or otherwise
prohibiting the Merger, which order, decree, ruling or other action is final and
nonappealable;

                  (d) by the Company or Parent if the required approval of the
stockholders of Parent contemplated by this Agreement shall not have been
obtained by reason of the failure to 


<PAGE>   59

obtain the required vote at a meeting of Parent stockholders duly convened
therefor or at any adjournment thereof; provided, however, that the right to
terminate this Agreement under this Section 7.1(d) shall not be available to
Parent where the failure to obtain Parent stockholder approval shall have been
caused by (i) the action or failure to act of Parent and such action or failure
to act constitutes a material breach by Parent of this Agreement or (ii) a
breach by TCI of its Parent Voting Agreement.

                  (e) by the Company or Parent if the required approval of the
stockholders of the Company contemplated by this Agreement shall not have been
obtained by reason of the failure to obtain the required vote at a meeting of
the Company stockholders duly convened therefore or at any adjournment thereof;
provided, however, that the right to terminate this Agreement under this Section
7.1(e) shall not be available to the Company where the failure to obtain the
Company stockholder approval shall have been caused by (i) the action or failure
to act of the Company and such action or failure to act constitutes a material
breach by the Company of this Agreement or (ii) a breach of any Company Voting
Agreement by any party thereto other than Parent.

                  (f) by Parent (at any time prior to the adoption and approval
of this Agreement and the Merger by the required vote of the stockholders of the
Company) if a Company Triggering Event (as defined below) shall have occurred;

                  (g) by the Company, upon a breach of any representation,
warranty, covenant or agreement on the part of Parent set forth in this
Agreement, or if any representation or warranty of Parent shall have become
untrue, in either case such that the conditions set forth in Section 6.2(a) or
Section 6.2(b) would not be satisfied as of the time of such breach or as of the
time such representation or warranty shall have become untrue, provided that if
such inaccuracy in Parent's representations and warranties or breach by Parent
is curable by Parent through the exercise of its commercially reasonable
efforts, then the Company may not terminate this Agreement under this Section
7.1(g) prior to the End Date, provided Parent continues to exercise commercially
reasonable efforts to cure such breach (it being understood that the Company may
not terminate this Agreement pursuant to this paragraph (g) if it shall have
materially breached this Agreement or if such breach by Parent is cured prior to
the End Date);

                  (h) by Parent, upon a breach of any representation, warranty,
covenant or agreement on the part of the Company set forth in this Agreement, or
if any representation or warranty of the Company shall have become untrue, in
either case such that the conditions set forth in Section 6.3(a) or Section
6.3(b) would not be satisfied as of the time of such breach or as of the time
such representation or warranty shall have become untrue, provided, that if such
inaccuracy in the Company's representations and warranties or breach by the
Company is curable by the Company through the exercise of its commercially
reasonable efforts, then Parent may not terminate this Agreement under this
Section 7.1(h) prior to the End Date, provided the Company continues to exercise
commercially reasonable efforts to cure such breach (it being understood that
Parent may not terminate this Agreement pursuant to this paragraph (h) if it
shall have materially breached this Agreement or if such breach by the Company
is cured prior to the End Date).

<PAGE>   60

         For the purposes of this Agreement, a "COMPANY TRIGGERING EVENT" shall
be deemed to have occurred if: (i) the Board of Directors of the Company or any
committee thereof shall for any reason have withdrawn or shall have amended or
modified in a manner adverse to Parent its unanimous recommendation in favor of,
the adoption and approval of the Agreement or the approval of the Merger; (ii)
the Company shall have failed to include in the Prospectus/Proxy Statement the
unanimous recommendation of the Board of Directors of the Company in favor of
the adoption and approval of the Agreement and the approval of the Merger; (iii)
the Board of Directors of the Company fails to reaffirm its unanimous
recommendation in favor of the adoption and approval of the Agreement and the
approval of the Merger within ten (10) days after Parent requests in writing
that such recommendation be reaffirmed; (iv) the Board of Directors of the
Company or any committee thereof shall have approved or recommended any
Acquisition Proposal; or (v) a tender or exchange offer relating to securities
of the Company shall have been commenced by a Person unaffiliated with Parent
and the Company shall not have sent to its securityholders pursuant to Rule
14e-2 promulgated under the Securities Act, within ten (10) business days after
such tender or exchange offer is first published, sent or given, a statement
disclosing that the Company recommends rejection of such tender or exchange
offer.

         7.2 Notice of Termination; Effect of Termination. Any termination of
this Agreement under Section 7.1 above will be effective immediately upon the
delivery of a valid written notice of the terminating party to the other parties
hereto. In the event of the termination of this Agreement as provided in Section
7.1, this Agreement shall be of no further force or effect, except (i) as set
forth in Section 5.4(a), this Section 7.2, Section 7.3 and Article 8
(miscellaneous), each of which shall survive the termination of this Agreement,
and (ii) nothing herein shall relieve any party from liability for any willful
breach of this Agreement. No termination of this Agreement shall affect the
obligations of the parties contained in the Confidentiality Agreement, all of
which obligations shall survive termination of this Agreement in accordance with
their terms.

         7.3      Fees and Expenses.

                  (a) General. Except as set forth in this Section 7.3, all fees
and expenses incurred in connection with this Agreement and the transactions
contemplated hereby shall be paid by the party incurring such expenses whether
or not the Merger is consummated; provided, however, that Parent and the Company
shall share equally all fees and expenses, other than attorneys' and accountants
fees and expenses, incurred in relation to the printing and filing (with the
SEC) of the Prospectus/Proxy Statement (including any preliminary materials
related thereto) and the Registration Statement (including financial statements
and exhibits) and any amendments or supplements thereto.

                  (b) Company Payments. In the event that this Agreement is
terminated by Parent or the Company, as applicable, pursuant to Sections 7.1(b),
(e) or (f), the Company shall promptly, but in no event later than two days
after the date of such termination, pay Parent a fee equal to $200


<PAGE>   61

million in immediately available funds (the "TERMINATION FEE"); provided, that
in the case of termination under Section 7.1(b) or 7.1(e), (i) such payment
shall be made only if following the date hereof and prior to the termination of
this Agreement, a third party has publicly announced an Acquisition Proposal and
within 12 months following the termination of this Agreement a Company
Acquisition (as defined below) is consummated or the Company enters into an
agreement providing for a Company Acquisition and (ii) such payment shall be
made promptly, but in no event later than two days after the consummation of
such Company Acquisition or the entry by the Company into such agreement. The
Company acknowledges that the agreements contained in this Section 7.3(b) are an
integral part of the transactions contemplated by this Agreement, and that,
without these agreements, Parent would not enter into this Agreement;
accordingly, if the Company fails to pay in a timely manner the amounts due
pursuant to this Section 7.3(b) , and, in order to obtain such payment, Parent
makes a claim that results in a judgment against the Company for the amounts set
forth in this Section 7.3(b), the Company shall pay to Parent its reasonable
costs and expenses (including reasonable attorneys' fees and expenses) in
connection with such suit, together with interest on the amounts set forth in
this Section 7.3(b) at the prime rate of The Chase Manhattan Bank in effect on
the date such payment was required to be made. Payment of the fees described in
this Section 7.3(b) shall not be in lieu of damages incurred in the event of
breach of this Agreement. For the purposes of this Agreement "COMPANY
ACQUISITION" shall mean any of the following transactions (other than the
transactions contemplated by this Agreement); (i) a merger, consolidation,
business combination, recapitalization, liquidation, dissolution or similar
transaction involving the Company pursuant to which the stockholders of the
Company immediately preceding such transaction hold less than 50% of the
aggregate equity interests in the surviving or resulting entity of such
transaction, (ii) a sale or other disposition by the Company of assets
representing in excess of 50% of the aggregate fair market value of the
Company's business immediately prior to such sale or (iii) the acquisition by
any person or group (including by way of a tender offer or an exchange offer or
issuance by the Company), directly or indirectly, of beneficial ownership or a
right to acquire beneficial ownership of shares representing in excess of 50% of
the voting power of the then outstanding shares of capital stock of the Company.

         7.4 Amendment. Subject to applicable law, this Agreement may be amended
by the parties hereto at any time by execution of an instrument in writing
signed on behalf of each of Parent and the Company.

         7.5 Extension; Waiver. At any time prior to the Effective Time any
party hereto may, to the extent legally allowed, (i) extend the time for the
performance of any of the obligations or other acts of the other parties hereto,
(ii) waive any inaccuracies in the representations and warranties made to such
party contained herein or in any document delivered pursuant hereto and (iii)
waive compliance with any of the agreements or conditions for the benefit of
such party contained herein. Any agreement on the part of a party hereto to any
such extension or waiver shall be valid only if set forth in an instrument in
writing signed on behalf of such party. Delay in exercising any right under this
Agreement shall not constitute a waiver of such right.

words "INCLUDE," "INCLUDES" and "INCLUDING" when used herein shall be deemed in
each case to be followed by the words "without limitation." The table of

only and shall not affect in any way the meaning or interpretation of this
Agreement. When reference is made herein to "THE BUSINESS OF" an entity, such

deemed to include all direct and indirect subsidiaries of such entity. An

violation, inaccuracy, circumstance or effect that is or is reasonably likely to
be materially adverse to the business, assets (including intangible assets),
capitalization, financial condition or results of operations of such entity
taken as a whole with its subsidiaries, except to the extent that any such
change, event, violation, inaccuracy, circumstance or effect directly and
primarily results from (i) the direct effect of the public announcement,
pendency or consummation of the transactions contemplated hereby on current or
prospective advertisers or sponsors of such entity or revenues therefrom
(provided that the exception in this clause (i) shall not apply to the use of
the term "Material Adverse Effect" in Sections 6.2(a) and 6.3(a) with respect to

         8.4 Counterparts. This Agreement may be executed in one or more
counterparts, all of which shall be considered one and the same agreement and
shall become effective when one or more counterparts have been signed by each of
the parties and delivered to the other party, it being understood that all
parties need not sign the same counterpart.

         8.5 Entire Agreement; Third Party Beneficiaries. This Agreement and the
documents and instruments and other agreements among the parties hereto as
contemplated by or referred to herein, including the Company Schedules and the
Parent Schedules (a) constitute the entire agreement among the parties with
respect to the subject matter hereof and supersede all prior agreements and
understandings, both written and oral, among the parties with respect to the
subject matter hereof, it being understood that the Confidentiality Agreement
shall continue in full force and effect until the Closing and shall survive any
termination of this Agreement; and (b) are not intended to confer upon any other
person any rights or remedies hereunder, except as specifically provided in
Section 5.11.

         8.6 Severability. In the event that any provision of this Agreement or
the application thereof, becomes or is declared by a court of competent
jurisdiction to be illegal, void or unenforceable, the remainder of this
Agreement will continue in full force and effect and the application of such
provision to other persons or circumstances will be interpreted so as reasonably
to effect the intent of the parties hereto. The parties further agree to replace
such void or unenforceable provision of this Agreement with a valid and
enforceable provision that will achieve, to the extent possible, the economic,
business and other purposes of such void or unenforceable provision.

         8.7 Other Remedies; Specific Performance. Except as otherwise provided
herein, any and all remedies herein expressly conferred upon a party will be
deemed cumulative with and not exclusive of any other remedy conferred hereby,
or by law or equity upon such party, and the exercise by a party of any one
remedy will not preclude the exercise of any other remedy. The parties hereto
agree that irreparable damage would occur in the event that any of the
provisions of this Agreement were not performed in accordance with their
specific terms or were otherwise breached. It is accordingly agreed that the
parties shall be entitled to seek an injunction or


<PAGE>   65

injunctions to prevent breaches of this Agreement and to enforce specifically
the terms and provisions hereof in any court of the United States or any state
having jurisdiction, this being in addition to any other remedy to which they
are entitled at law or in equity.

         8.8 Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of Delaware, regardless of the laws that
might otherwise govern under applicable principles of conflicts of law thereof.

         8.9 Rules of Construction. The parties hereto agree that they have been
represented by counsel during the negotiation and execution of this Agreement
and, therefore, waive the application of any law, regulation, holding or rule of
construction providing that ambiguities in an agreement or other document will
be construed against the party drafting such agreement or document.

         8.10 Assignment. No party may assign either this Agreement or any of
its rights, interests, or obligations hereunder without the prior written
approval of the other parties. Any purported assignment in violation of this
Section 8.10 shall be void. Subject to the preceding sentence, this Agreement
shall be binding upon and shall inure to the benefit of the parties hereto and

                             STOCK OPTION AGREEMENT


         THIS STOCK OPTION AGREEMENT dated as of January 19, 1999 (the
"AGREEMENT") is entered into by and between Excite, Inc., a Delaware corporation
(the "COMPANY") and At Home Corporation, a Delaware corporation ("PARENT").
Capitalized terms used in this Agreement but not defined herein shall have the
meanings ascribed thereto in the Merger Agreement (as defined below).

                                    RECITALS

         A. Concurrently with the execution and delivery of this Agreement, the
Company, Parent and Countdown Merger Corp., a Delaware corporation and a wholly
owned subsidiary of Parent ("SUB"), are entering into an Agreement and Plan of
Reorganization (the "MERGER AGREEMENT"), which provides that, among other
things, upon the terms and subject to the conditions thereof, the Company and
Parent will enter into a business combination transaction (the "MERGER").

         B. As a condition to Parent's willingness to enter into the Merger
Agreement, Parent has requested that the Company agree, and the Company has so
agreed, to grant to Parent an option to acquire shares of the Company's Common
Stock, $0.001 par value (including the associated rights (the "RIGHTS") to
purchase shares of the Company's Preferred Stock pursuant to the Rights
Agreement, dated as of October 15, 1998, between the Company and BankBoston,
N.A., as Rights Agent (the "RIGHTS AGREEMENT")) (together, "COMPANY SHARES"),
upon the terms and subject to the conditions set forth herein.

                                    AGREEMENT

         NOW, THEREFORE, in consideration of the foregoing and of the mutual
covenants and agreements set forth herein and in the Merger Agreement and for
other good and valuable consideration, the receipt and adequacy of which are
hereby acknowledged, the parties hereto agree as follows:

         1.       GRANT OF OPTION

         The Company hereby grants to Parent an irrevocable option (the
"OPTION") to acquire up to a number of Company Shares equal to 19.9% of the
issued and outstanding shares of common stock of the Company as of the first
date, if any, upon which an Exercise Event (as defined in Section 2(a) below)
shall occur (the "OPTION SHARES"), in the manner set forth below by paying cash
at a price of $106.60 per share (the "EXERCISE PRICE"). All references in this
Agreement to Company Shares issued to Parent hereunder shall be deemed to
include the associated Rights (subject to the terms of the Rights Agreement).

         2.       EXERCISE OF OPTION; MAXIMUM PROCEEDS

<PAGE>   2

                  (a) For all purposes of this Agreement, an "EXERCISE EVENT"
shall mean the occurrence of any of (i) a Company Triggering Event (as such term
is defined in the Merger Agreement), (ii) the public announcement of an Option
Acquisition Proposal (as defined below) or (iii) the commencement of a
solicitation within the meaning of Rule 14a-1(l) by any person or entity other
than the Company or its Board of Directors (or any person or entity acting on
behalf of the Company or its Board of Directors) seeking to alter the
composition of the Company's Board of Directors. For purposes of this Agreement,
"OPTION ACQUISITION PROPOSAL" shall mean any offer or proposal (other than an
offer or proposal by Parent) relating to any transaction or series of related
transactions involving: (A) any purchase from the Company or acquisition by any
person or "group" (as defined under Section 13(d) of the Exchange Act and the
rules and regulations thereunder) of more than a 10% interest in the total
outstanding voting securities of the Company or any of its subsidiaries or any
tender offer or exchange offer that if consummated would result in any person or
"group" (as defined under Section 13(d) of the Exchange Act and the rules and
regulations thereunder) beneficially owning 10% or more of the total outstanding
voting securities of the Company or any of its subsidiaries or any merger,
consolidation, business combination or similar transaction involving the
Company; (B) any sale, lease (other than in the ordinary course of business),
exchange, transfer, license (other than in the ordinary course of business),
acquisition or disposition of more than 10% of the assets of the Company; or (C)
any liquidation or dissolution of the Company.

                  (b) Parent may deliver to the Company a written notice (an
"EXERCISE NOTICE") specifying that it wishes to exercise and close a purchase of
Option Shares at any time following the occurrence of an Exercise Event and
specifying the total number of Option Shares it wishes to acquire. Unless such
Exercise Notice is withdrawn by Parent, the closing of a purchase of Option
Shares (a "CLOSING") specified in such Exercise Notice shall take place at the
principal offices of the Company upon such date prior to the termination of the
Option as may be designated by Parent in writing.

                  (c) The Option shall terminate upon the earliest to occur of
(i) the Effective Time (as such term is defined in the Merger Agreement), (ii)
termination of the Merger Agreement pursuant to any of Section 7.1(a), 7.1(c),
7.1(d) or 7.1(g) thereof, (iii) termination of the Merger Agreement pursuant to
either of Section 7.1(b) or 7.1(e) thereof if prior thereto no Exercise Event
shall have occurred, or (ii) 18 months following the termination of the Merger
Agreement under any other circumstances; provided, however, that if the Option
is exercisable but cannot be exercised by reason of any applicable government
order or because the waiting period related to the issuance of the Option Shares
under the HSR Act (as such term is defined in the Merger Agreement) shall not
have expired or been terminated, or because any other condition to closing has
not been satisfied, then the Option shall not terminate until the tenth business
day after such impediment to exercise shall have been removed or shall have
become final and not subject to appeal.

                  (d) If Parent receives proceeds in connection with any sales
or other dispositions of Option Shares or this Option (including by selling
Option Shares to the Company pursuant to 


<PAGE>   3

Section 6(a) hereof), plus any dividends (or equivalent distributions under
Section 7(a) hereof) received by Parent declared on Option Shares, of more than
the sum of (x) $35 million plus (y) the Exercise Price multiplied by the number
of Company Shares purchased by Parent pursuant to the Option, then all proceeds
to Parent in excess of such sum shall be promptly remitted in cash by Parent to
the Company.

         3.       CONDITIONS TO CLOSING

         The obligation of the Company to issue Option Shares to Parent
hereunder is subject to the conditions that (a) any waiting period under the HSR
Act applicable to the issuance of the Option Shares hereunder shall have expired
or been terminated; (b) all material consents, approvals, orders or
authorizations of, or registrations, declarations or filings with, any Federal,
state or local administrative agency or commission or other Federal state or
local governmental authority or instrumentality, if any, required in connection
with the issuance of the Option Shares hereunder shall have been obtained or
made, as the case may be; and (c) no preliminary or permanent injunction or
other order by any court of competent jurisdiction prohibiting or otherwise
restraining such issuance shall be in effect. It is understood and agreed that
at any time during which Parent shall be entitled to deliver to the Company an
Exercise Notice, the parties will use their respective reasonable efforts to
satisfy all conditions to Closing, so that a Closing may take place as promptly
as practicable.

         4.       CLOSING

         At any Closing, (a) the Company shall deliver to Parent a single
certificate in definitive form representing the number of Company Shares
designated by Parent in its Exercise Notice consistent with this Agreement, such
certificate to be registered in the name of Parent and to bear the legend set
forth in Section 9 hereof, against delivery of (b) payment by Parent to the
Company of the aggregate purchase price for the Company Shares so designated and
being purchased by delivery of a certified check or bank check in immediately
available funds.

         5.       REPRESENTATIONS AND WARRANTIES OF THE COMPANY

         The Company represents and warrants to Parent that (a) the Company is a
corporation duly organized, validly existing and in good standing under the laws
of the State of Delaware and has the corporate power and authority to enter into
this Agreement and to carry out its obligations hereunder; (b) the execution and
delivery of this Agreement by the Company and consummation by the Company of the
transactions contemplated hereby have been duly authorized by all necessary
corporate action on the part of the Company and no other corporate proceedings
on the part of the Company are necessary to authorize this Agreement or any of
the transactions contemplated hereby; (c) this Agreement has been duly executed
and delivered by the Company and constitutes a legal, valid and binding
obligation of the Company and, assuming this Agreement constitutes a legal,
valid and binding obligation of Parent, is enforceable against the Company in
accordance with its terms, except as enforceability may be limited by principles
of public policy, bankruptcy and by rules of 


<PAGE>   4

law governing specific performance, injunctive relief and other equitable
remedies; (d) except for any filings, authorizations, approvals or orders
required under the HSR Act and the filing of a notice on Form 25102(f) pursuant
to the California Corporate Securities Rules and Regulations, the Company has
taken all necessary corporate and other action to authorize and reserve for
issuance and to permit it to issue upon exercise of the Option, and at all times
from the date hereof until the termination of the Option will have reserved for
issuance, a sufficient number of unissued Company Shares for Parent to exercise
the Option in full and will take all necessary corporate or other action to
authorize and reserve for issuance all additional Company Shares or other
securities which may be issuable pursuant to Section 7(a) upon exercise of the
Option, all of which, upon their issuance and delivery in accordance with the
terms of this Agreement and payment therefor by Parent, will be validly issued,
fully paid and nonassessable; (e) upon delivery of the Company Shares and any
other securities to Parent upon exercise of the Option, Parent will acquire such
Company Shares or other securities free and clear of all material claims, liens,
charges, encumbrances and security interests of any kind or nature whatsoever,
excluding those imposed by Parent; (f) the execution and delivery of this
Agreement by the Company do not, and the performance of this Agreement by the
Company will not, (i) violate the Certificate of Incorporation or Bylaws of the
Company, (ii) conflict with or violate any order applicable to the Company or
any of its subsidiaries or by which they or any of their material property is
bound or affected or (iii) result in any breach of or constitute a default (or
an event which with notice or lapse of time or both would become a default)
under, or give rise to any right of termination, amendment, acceleration or
cancellation of, or result in the creation of a material lien or encumbrance on
any material property or assets of the Company or any of its subsidiaries
pursuant to, any material contract or agreement to which the Company or any of
its subsidiaries is a party or by which the Company or any of its subsidiaries
or any of their material property is bound or affected; and (g) the execution
and delivery of this Agreement by the Company does not, and the performance of
this Agreement by the Company will not, require any consent, approval,
authorization or permit of, or filing with, or notification to, any Governmental
Entity (as such term is defined in the Merger Agreement) except pursuant to the
HSR Act.

         6.       REGISTRATION RIGHTS

                  (a) Following the termination of the Merger Agreement, Parent
(sometimes referred to herein as the "HOLDER") may by written notice (sometimes
referred to herein as the "REGISTRATION NOTICE") to the Company (the
"REGISTRANT") request the Registrant to register under the Securities Act all or
any part of the shares acquired by the Holder pursuant to this Agreement (such
shares requested to be registered the "REGISTRABLE SECURITIES") in order to
permit the sale or other disposition of such shares pursuant to a bona fide firm
commitment underwritten public offering in which the Holder and the underwriters
shall effect as wide a distribution of such Registrable Securities as is
reasonably practicable and shall use reasonable efforts to prevent any person or
group from purchasing through such offering shares representing more than 1% of
the outstanding shares of Common Stock of the Registrant on a fully diluted
basis (a "PERMITTED OFFERING"); provided, however, that any such Registration
Notice must relate to a number of shares equal to at least 2% of the outstanding
shares of Common Stock of the Registrant on a fully diluted basis and that any
rights to require registration hereunder shall terminate with respect to any
shares 


<PAGE>   5

that may be sold pursuant to Rule 144(k) under the Securities Act or at such
time as all of the Registrable Securities may be sold in any three month period
pursuant to Rule 144 under the Securities Act. The Registration Notice shall
include a certificate executed by the Holder and its proposed managing
underwriter, which underwriter shall be an investment banking firm of
internationally recognized standing reasonably acceptable to the Company (the
"MANAGER"), stating that (i) the Holder and the Manager have a good faith
intention to commence a Permitted Offering and (ii) the Manager in good faith
believes that, based on the then prevailing market conditions, it will be able
to sell the Registrable Securities at a per share price equal to at least 80% of
the per share average of the closing sale prices of the Registrant's Common
Stock on the Nasdaq National Market for the twenty trading days immediately
preceding the date of the Registration Notice. The Registrant shall thereupon
have the option exercisable by written notice delivered to the Holder within
five business days after the receipt of the Registration Notice, irrevocably to
agree to purchase all (but not less than all) of the Registrable Securities for
cash at a price (the "OPTION PRICE") equal to the product of (i) the number of
Registrable Securities so purchased and (ii) the per share average of the
closing sale prices of the Registrant's Common Stock on the Nasdaq National
Market for the twenty trading days immediately preceding the date of the
Registration Notice. Any such purchase of Registrable Securities by the
Registrant hereunder shall take place at a closing to be held at the principal
executive offices of the Registrant or its counsel at any reasonable date and
time designated by the Registrant in such notice within 10 business days after
delivery of such notice. The payment for the shares to be purchased shall be
made by delivery at the time of such closing of the Option Price in immediately
available funds.

                  (b) If the Registrant does not elect to exercise its option to
purchase pursuant to Section 6(a) with respect to all Registrable Securities,
the Registrant shall use all reasonable efforts to effect, as promptly as
practicable, the registration under the Securities Act of the Registrable
Securities requested to be registered in the Registration Notice; provided,
however, that (i) the Holder shall not be entitled to more than an aggregate of
two effective registration statements hereunder, provided however, that if the
Registrant withdraws a filed registration statement at the request of the Holder
(other than as the result of a material change in the Registrant's business or
the Holder's learning of new material information concerning the Registrant),
then such filing shall be deemed to have been an effective registration for
purposes of this clause (i), (ii) the Registrant will not be required to file
any such registration statement during any period of time (not to exceed 45 days
after a Registration Notice in the case of clause (A) below or 90 days after a
Registration Notice in the case of clauses (B) and (C) below) when (A) the
Registrant is in possession of material non-public information which it
reasonably believes would be detrimental to be disclosed at such time and such
information would have to be disclosed if a registration statement were filed at
that time; (B) the Registrant is required under the Securities Act to include
audited financial statements for any period in such registration statement and
such financial statements are not yet available for inclusion in such
registration statement; or (C) the Registrant determines, in its reasonable
judgment, that such registration would interfere with any financing, acquisition
or other material transaction involving the Registrant and (iii) the Registrant
will not be required to maintain the effectiveness of any such registration
statement for a period greater than 60 days. If consummation of the sale of any
Registrable Securities pursuant to a registration hereunder does not occur
within 180 days after the


<PAGE>   6

filing with the SEC of the initial registration statement therefor, the
provisions of this Section 6 shall again be applicable to any proposed
registration. The Registrant shall use all reasonable efforts to cause any
Registrable Securities registered pursuant to this Section 6 to be qualified for
sale under the securities or blue sky laws of such jurisdictions as the Holder
may reasonably request and shall continue such registration or qualification in
effect in such jurisdictions until the Holder has sold or otherwise disposed of
all of the securities subject to the registration statement; provided, however,
that the Registrant shall not be required to qualify to do business in, or
consent to general service of process in, any jurisdiction by reason of this
provision.

                  (c) The registration rights set forth in this Section 6 are
subject to the condition that the Holder shall provide the Registrant with such
information with respect to the Holder's Registrable Securities, the plan for
distribution thereof, and such other information with respect to the Holder as,
in the reasonable judgment of counsel for the Registrant, is necessary to enable
the Registrant to include in a registration statement all material facts
required to be disclosed with respect to a registration thereunder, including
the identity of the Holder and the Holder's plan of distribution.

                  (d) A registration effected under this Section 6 shall be
effected at the Registrant's expense, except for underwriting discounts and
commissions and the fees and expenses of counsel to the Holder, and the
Registrant shall use all reasonable efforts to provide to the underwriters such
documentation (including certificates, opinions of counsel and "comfort" letters
from auditors) as are customary in connection with underwritten public offerings
and as such underwriters may reasonably require. In connection with any
registration, the Holder and the Registrant agree to enter into an underwriting
agreement reasonably acceptable to each such party, in form and substance
customary for transactions of this type with the underwriters participating in
such offering.

                  (e)      Indemnification

                           (i) The Registrant will indemnify the Holder, each of
its directors and officers and each person who controls the Holder within the
meaning of Section 15 of the Securities Act, and each underwriter of the
Registrant's securities, with respect to any registration, qualification or
compliance which has been effected pursuant to this Agreement, against all
expenses, claims, losses, damages or liabilities (or actions in respect
thereof), including any of the foregoing incurred in settlement of any
litigation, commenced or threatened, arising out of or based on any untrue
statement (or alleged untrue statement) of a material fact contained in any
registration statement, prospectus, offering circular or other document, or any
amendment or supplement thereto, incident to any such registration,
qualification or compliance, or based on any omission (or alleged omission) to
state therein a material fact required to be stated therein or necessary to make
the statements therein, in light of the circumstances in which they were made,
not misleading, or any violation by the Registrant of any rule or regulation
promulgated under the Securities Act applicable to the Registrant in connection
with any such registration, qualification or compliance, and the Registrant will
reimburse the Holder and, each of its directors and officers and each person who
controls the Holder within the meaning of Section 15 of the Securities Act,


<PAGE>   7

and each underwriter for any legal and any other expenses reasonably incurred in
connection with investigating, preparing or defending any such claim, loss,
damage, liability or action, provided that the Registrant will not be liable in
any such case to the extent that any such claim, loss, damage, liability or
expense arises out of or is based on any untrue statement or omission or alleged
untrue statement or omission, made in reliance upon and in conformity with
written information furnished to the Registrant by the Holder or director or
officer or controlling person or underwriter seeking indemnification, provided,
however, that the indemnity agreement contained in this subsection 6(e)(i) shall
not apply to amounts paid in settlement of any such loss, claim, damage,
liability or action if such settlement is effected without the consent of the
Registrant, which consent shall not be unreasonably withheld.

                           (ii) The Holder will indemnify the Registrant, each
of its directors and officers and each underwriter of the Registrant's
securities covered by such registration statement and each person who controls
the Registrant within the meaning of Section 15 of the Securities Act, against
all claims, losses, damages and liabilities (or actions in respect thereof),
including any of the foregoing incurred in settlement of any litigation,
commenced or threatened, arising out of or based on any untrue statement (or
alleged untrue statement) of a material fact contained in any such registration
statement, prospectus, offering circular or other document, or any omission (or
alleged omission) to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, or any violation by
the Holder of any rule or regulation promulgated under the Securities Act
applicable to the Holder in connection with any such registration, qualification
or compliance, and will reimburse the Registrant, such directors, officers or
control persons or underwriters for any legal or any other expenses reasonably
incurred in connection with investigating, preparing or defending any such
claim, loss, damage, liability or action, in each case to the extent, but only
to the extent, that such untrue statement (or alleged untrue statement) or
omission (or alleged omission) is made in such registration statement,
prospectus, offering circular or other document in reliance upon and in
conformity with written information furnished to the Registrant by the Holder
expressly for use therein, provided that in no event shall any indemnity under
this Section 6(e) exceed the gross proceeds of the offering received by the
Holder and provided further that the indemnity agreement contained in this
subsection 6(e)(ii) shall not apply to amounts paid in settlement of any such
loss, claim, damage, liability or action if such settlement is effected without
the consent of the Holder, which consent shall not be unreasonably withheld.

                           (iii) Each party entitled to indemnification under
this Section 6(e) (the "INDEMNIFIED PARTY") shall give notice to the party
required to provide indemnification (the "INDEMNIFYING PARTY") promptly after
such Indemnified Party has actual knowledge of any claim as to which indemnity
may be sought, and shall permit the Indemnifying Party to assume the defense of
any such claim or any litigation resulting therefrom, provided that counsel for
the Indemnifying Party, who shall conduct the defense of such claim or
litigation, shall be approved by the Indemnified Party (whose approval shall not
unreasonably be withheld), and the Indemnified Party may participate in such
defense at such party's expense; provided, however, that the Indemnifying Party
shall pay such expense if representation of the Indemnified Party by


<PAGE>   8

counsel retained by the Indemnifying Party would be inappropriate due to actual
or potential differing interests between the Indemnified Party and any other
party represented by such counsel in such proceeding, and provided further that
the failure of any Indemnified Party to give notice as provided herein shall not
relieve the Indemnifying Party of its obligations under this Section 6(e) unless
the failure to give such notice is materially prejudicial to an Indemnifying
Party's ability to defend such action. No Indemnifying Party, in the defense of
any such claim or litigation shall, except with the consent of each Indemnified
Party, consent to entry of any judgment or enter into any settlement which does
not include as an unconditional term thereof the giving by the claimant or
plaintiff to such Indemnified Party of a release from all liability in respect
to such claim or litigation. No Indemnifying Party shall be required to
indemnify any Indemnified Party with respect to any settlement entered into
without such Indemnifying Party's prior consent (which shall not be unreasonably
withheld).

         7.       ADJUSTMENT UPON CHANGES IN CAPITALIZATION; RIGHTS PLANS

                  (a) In the event of any change in the Company Shares by reason
of stock dividends, stock splits, reverse stock splits, mergers (other than the
Merger), recapitalizations, combinations, exchanges of shares and the like, the
type and number of shares or securities subject to the Option and the Exercise
Price shall be adjusted appropriately, and proper provision shall be made in the
agreements governing such transaction so that Parent shall receive, upon
exercise of the Option, the number and class of shares or other securities or
property that Parent would have received in respect of the Company Shares if the
Option had been exercised immediately prior to such event or the record date
therefor, as applicable.

                  (b) Prior to such time as the Option is terminated, and at any
time after the Option is exercised (in whole or in part, if at all), the Company
shall not amend (nor permit the amendment of) its Rights Agreement nor adopt
(nor permit the adoption of) a new stockholders rights plan that contains
provisions for the distribution or exercise of rights thereunder as a result of
Parent or any affiliate or transferee being the beneficial owner of shares of
the Company by virtue of the Option being exercisable or having been exercised
(or as a result of beneficially owning shares issuable in respect of any Option
Shares).

         8.       RESTRICTIVE LEGENDS

         Each certificate representing Option Shares issued to Parent hereunder
shall include a legend in substantially the following form:

         THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
         UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY BE REOFFERED OR
         SOLD ONLY IF SO REGISTERED OR IF AN EXEMPTION FROM SUCH REGISTRATION IS
         AVAILABLE. SUCH SECURITIES ARE ALSO SUBJECT TO ADDITIONAL RESTRICTIONS
         ON TRANSFER AS SET FORTH IN THE STOCK OPTION AGREEMENT DATED


<PAGE>   9

         AS OF JANUARY 19, 1999, A COPY OF WHICH MAY BE OBTAINED FROM THE
         ISSUER.

         9.       LISTING AND HSR FILING

         The Company, upon the request of Parent, shall promptly file an
application to list the Company Shares to be acquired upon exercise of the
Option for quotation on the Nasdaq National Market and shall use its reasonable
efforts to obtain approval of such listing as soon as practicable. Promptly
after the date hereof, each of the parties hereto shall promptly file with the
Federal Trade Commission and the Antitrust Division of the United States
Department of Justice all required premerger notification and report forms and
other documents and exhibits required to be filed under the HSR Act to permit
the acquisition of the Company Shares subject to the Option at the earliest
possible date.

         10.      BINDING EFFECT

         This Agreement shall be binding upon and inure to the benefit of the
parties hereto and their respective successors and permitted assigns. Nothing
contained in this Agreement, express or implied, is intended to confer upon any
person other than the parties hereto and their respective successors and
permitted assigns any rights or remedies of any nature whatsoever by reason of
this Agreement. Certificates representing shares sold in a registered public
offering pursuant to Section 6 shall not be required to bear the legend set
forth in Section 8.

         11.      SPECIFIC PERFORMANCE

         The parties recognize and agree that if for any reason any of the
provisions of this Agreement are not performed in accordance with their specific
terms or are otherwise breached, immediate and irreparable harm or injury would
be caused for which money damages would not be an adequate remedy. Accordingly,
each party agrees that in addition to other remedies the other party shall be
entitled to an injunction restraining any violation or threatened violation of
the provisions of this Agreement. In the event that any action shall be brought
in equity to enforce the provisions of the Agreement, neither party will allege,
and each party hereby waives the defense, that there is an adequate remedy at
law.

         12.      ENTIRE AGREEMENT

         This Agreement and the Merger Agreement (including the appendices and
exhibits thereto) constitute the entire agreement between the parties with
respect to the subject matter hereof and supersede all other prior agreements
and understandings, both written and oral, between the parties with respect to
the subject matter hereof.

         13.      FURTHER ASSURANCES


<PAGE>   10

         Each party will execute and deliver all such further documents and
instruments and take all such further action as may be necessary in order to
consummate the transactions contemplated hereby.

         14.      VALIDITY

         The invalidity or unenforceability of any provision of this Agreement
shall not affect the validity or enforceability of the other provisions of this
Agreement, which shall remain in full force and effect. In the event any
Governmental Entity of competent jurisdiction holds any provision of this
Agreement to be null, void or unenforceable, the parties hereto shall negotiate
in good faith and shall execute and deliver an amendment to this Agreement in
order, as nearly as possible, to effectuate, to the extent permitted by law, the
intent of the parties hereto with respect to such provision.

@Home Network and Excite to Merge

"Excite @Home" Defines Media Network of the Next Century

Combination Will Accelerate and Lower Cost of Broadband Adoption

NEW YORK, NY, January 19, 1999 -- @Home Network and Excite, Inc. today announced
that the companies have signed a definitive merger agreement for an all-stock
transaction valued at approximately $6.7 billion at the time of the
announcement. The combined organizations aim to accelerate broadband deployment
and adoption by combining @Home's broadband technology platform, robust Internet
backbone, and cable distribution agreements representing nearly 60 million homes
worldwide, with Excite's award-winning Web portal and extensive narrowband
reach. Excite and @Home will deliver to consumers the most personalized, open
Internet services at any speed, any time, and on any device they choose.

@Home Network remains committed to full and open access to the entire Web. All
Excite and @Home offerings are built on a commitment to personalized media
services and open access to all the information, community and entertainment of
the Web. Every "Excite @Home" user's rich, personalized experience will include
simple "point and click" access to any and all content and services on the Web.

Under the agreement, @Home Network will issue 1.041902 shares of At Home
Corporation Series A common stock for each share of Excite, Inc. stock. The
purchase transaction, which is expected to close in approximately three months,
has been approved by both companies' Boards of Directors and is subject to
approval by @Home and Excite's stockholders. The acquisition also is subject to
certain customary conditions, including obtaining necessary regulatory
approvals. The agreement also provides @Home Network an option to acquire a
19.9% interest in Excite which becomes exercisable under certain customary
circumstances. With almost no duplication of function, the resulting company
expects to add significantly to its employee base to exploit new opportunities.
At closing, George Bell, CEO of Excite, Inc., will continue in that role as
Excite becomes a subsidiary of @Home, reporting to Tom Jermoluk, chairman and
CEO of @Home Network. In addition, Bell will join the @Home Network Board of
Directors.

A New Communications Company The success and popularity of Web portals
underscores the value of Internet content, communication and community. However,
the biggest barrier to mainstream consumer adoption of the Internet has been the
lack of speed and "always-on" capability. The companies aim to accelerate
broadband adoption by exposing the millions of Excite narrowband users to the
benefits of a media experience enhanced by the broadband platform.

"We are merging with Excite not only for what they have achieved, but what we
become together - the new media network for the 21st century," said Tom
Jermoluk, Chairman and CEO, @Home Network. "The ubiquitous reach of dial-up
access combined with the fast expanding footprint of broadband gives consumers
the ability to seamlessly migrate between services at different speeds and
devices with a consistent interface. Excite and @Home will give consumers access
to the information they want, when they want it, whether they are using a PC,
TV, or any other communications device."

"This merger brings together the leading broadband technology company with a
leader in Internet personalization and media," said George Bell, CEO of Excite,
Inc. "In addition, this combination brings to advertisers the most powerful
interactive marketing solutions available - the ability to target, measure, and
report their advertising in a single, unified venue across narrowband,
broadband, and ultimately all devices."

All Band, All Device, All the Time Through the Excite portal, Excite and @Home
will deliver a consistent personalized interface across narrowband and broadband
services and ultimately multiple display devices. The new company will give
consumers choice over how they access information over various communications
devices such as a pager, PC, or TV, and how they organize and personalize
content. With Excite and @Home, consumers can submit their personal information
and preferences only once and they'll be able reap the benefits of personalized
services across multiple devices and platforms anytime and anywhere.

"On its own and when integrated with the broad range of AT&T communications
services, the @Home and Excite combination will provide the consumer with a
compelling interactive experience full of additional choice and opportunities,"
said C. Michael Armstrong, chairman and CEO of AT&T, which will become a major
stockholder of @Home Network following AT&T's pending acquisition of
Tele-Communications, Inc. (TCI). "This marks a new era of open choice and
capability for consumers. You can count on AT&T WorldNet service, which already
has a business relationship with Excite, to champion this new, 'allband' portal,
while combining it with AT&T's IP and traditional communications services."

Advertising Across All Platforms Through Excite's MatchLogic division, Excite
and @Home will, for the first time, offer advertisers a unified way to target,
measure, and report advertising on all devices on which the Excite and @Home
combination is offered. The new company will combine MatchLogic's unique
marketing skills with the rich media technologies of @Home's recently acquired
Enliven Business Unit (formerly Narrative Communications).

With MatchLogic's direct marketing strengths, Excite and @Home plan to build one
of the largest predictive consumer databases, combining Excite's 20 million
registered users with @Home's service footprint of nearly 60 million homes
worldwide. MatchLogic will continue to build this database and offer its unique
one-to-one marketing services to advertisers on narrowband, broadband and
multiple devices.

risks and uncertainties, including and without limitation: risks related to the
consummation of the merger of @Home and Excite; risks involved in assimilating
Excite; risks involved in retaining and motivating key Excite personnel, who are

negative cash flow and increased operating expenses arising out of, among other
items, the proposed Excite merger; risks inherent in Excite's business; risks
related to the achievement of new revenue to @Home from the Excite operations,
including the extremely limited operating history of Excite on which to base any

advertising customers of the merger; and Excite continuing to serve its existing
