warranties to Excite@Home, and will agree to irrevocably vote all shares of
Kendara capital stock owned by such Kendara Founder in favor of the Merger and

Letter").

     D.   Immediately prior to the Effective Time (as defined in Section 1.8) of
the Merger, all shares of Kendara Preferred Stock (as defined in Section 1.15)
outstanding as of immediately prior to the Effective Time will convert into
shares of Kendara Common Stock (as defined in Section 1.11) at the then
applicable conversion ratio defined in the Certificate of Incorporation of
Kendara, as amended to date.

     E.   Upon the Effective Time of the Merger, and subject to the terms and
conditions hereof, (i) the shares of capital stock of Kendara that are
outstanding immediately prior to the effectiveness of the Merger will be
converted into shares of the Series A Common Stock of Excite@Home, Series B Non-
Voting Convertible Preferred Stock of Excite@Home and Series C Non-Voting
Convertible Preferred Stock of Excite@Home, (ii) options, warrants and other
rights to purchase Kendara capital stock that are outstanding immediately prior

                            Plan of Reorganization

     2.1   Conversion of Shares.
           --------------------

        2.1.1  Conversion of Sub Stock.  At the Effective Time, each share of
               -----------------------
Sub common stock that is issued and outstanding immediately prior to the
Effective Time will continue after the Effective Time to be an identical
outstanding share of the Surviving Corporation (as defined below).

       2.1.2   Conversion of Kendara Common Stock.  Subject to the terms and
               ----------------------------------
conditions of this Agreement, at the Effective Time, each share of Kendara
Common Stock held by a Kendara Stockholder that is issued and outstanding
immediately prior to the Effective Time will, by virtue of the Merger and
without the need for any further action on the part of the holder thereof
(except as expressly provided herein), be converted into and represent the right
to receive the number of shares of Excite@Home Common Stock that is equal to the
Common Stock Conversion Number; provided, however, that (i) ten percent of the
shares of Kendara Common Stock held by the Kendara Stockholders (other than the
Kendara Founders) will be converted into and represent the right to receive, in
proportion to each such stockholder's interest, the number of shares of
Excite@Home Series B Preferred Stock that is equal to the product obtained by
multiplying (a) each share included in such ten percent of Kendara Common Stock
by (b) the quotient obtained by dividing the Common Stock Conversion Number by
1,000; (ii) twenty percent of Kendara Common Stock (other than Unvested Kendara
Shares, as defined in Section 2.1.5) held by the Kendara Founders will be
converted into and represent the right to receive, in proportion to each such
founder's interest, the number of shares of Excite@Home Series B Preferred Stock
that is equal to the product obtained by multiplying (a) each share included in
such twenty percent of Kendara Common Stock by (b) the quotient obtained by
dividing the Common Stock Conversion Number by 1,000, and (iii) each Unvested
Kendara Share held by a Kendara Founder will be converted into and represent the
right to receive the number of Excite@Home Series C Preferred Stock that is
equal to the quotient obtained by dividing the Common Stock Conversion Number by
1,000. The preceding provisions of this Section 2.1.2 are subject to the
provisions of Section 2.1.3 (regarding rights of holders of Dissenting Shares),
Section 2.1.4 (regarding the elimination of fractional shares of Excite@Home
Common Stock) and Section 2.5 (regarding the withholding of Escrow Shares).

       2.1.3   Dissenting Shares.  Holders of shares of Kendara Common Stock who
               -----------------
have complied with all requirements for perfecting stockholders' rights of
appraisal, as set forth in Section 262 of Delaware Law, shall be entitled to
their rights under the Delaware Law with respect to such shares ("Dissenting
Shares").

       2.1.4   Fractional Shares.  No fractional shares of Excite@Home Common
               -----------------
Stock will be issued in connection with the Merger. In lieu thereof, each holder
of Kendara Common Stock who would otherwise be entitled to receive a fraction of
a share of Excite@Home Common Stock pursuant to Section 2.1.2, computed after
aggregating all shares of Excite@Home

                                      -5-
<PAGE>

Common Stock to be received by such holder pursuant to Section 2.1.2, will
instead receive from Excite@Home, upon surrender of such holder's Kendara
Certificates pursuant to Article 7 hereof, an amount of cash (rounded to the
nearest cent) equal to the product obtained by multiplying (a) the Excite@Home
Average Price Per Share by (b) the fraction of a share of Excite@Home Common
Stock that such holder would otherwise have been entitled to receive.
Excite@Home Preferred Stock will be issued in fractional shares to the extent
conversion of Kendara Common Stock into Excite@Home Preferred Stock pursuant to
Section 2.1.2 results in the need to issue fractional shares of Excite@Home
Preferred Stock.

       2.1.5   Continuation of Vesting and Repurchase Rights.  If any shares of
               ---------------------------------------------
Kendara Common Stock (other than shares of Kendara Common Stock held by the
individuals listed on Schedule 2.1.5 ("Advisor Unvested Kendara Shares"))
outstanding immediately prior to the Effective Time are at the Effective Time
unvested or are subject to a repurchase option (other than a right of first
refusal) or any other condition providing that such shares may be forfeited to
Kendara upon any termination of the stockholder's employment, directorship or
other relationship with Kendara (and/or any affiliate of Kendara) under the
terms of any restricted stock purchase agreement, stock option agreement
(including any stock option agreement under the Kendara Plan (as defined below))
or other agreement with Kendara ("Unvested Kendara Shares"), then such
repurchase option or other condition shall be assigned to Excite@Home and the
shares of Excite@Home Common Stock or Excite@Home Series C Preferred Stock, as
the case may be, issued upon the conversion of such Unvested Kendara Shares in
the Merger will continue to be unvested and will continue to be subject to the
same repurchase options or conditions, as applicable, immediately following the
Effective Time as they were subject to immediately prior to the Effective Time;
and such repurchase options relating to Advisor Unvested Kendara Shares shall
not be assigned to Excite@Home and the shares of Excite@Home Common Stock or
Excite@Home Series C Preferred Stock, as the case may be, issued upon conversion
of such Advisor Unvested Kendara Shares will be vested but will not be subject
to any repurchase options or conditions, as applicable, immediately following
the Effective Time.   If shares of Kendara Common Stock held by a Kendara
Stockholder (other than a Kendara Founder) are Unvested Kendara Shares, ninety
percent of such Unvested Kendara Shares shall be converted into Excite@Home
Common Stock in accordance with Section 2.1.2 and the remaining ten percent
shall be converted into Excite@Home Series B Preferred Stock in accordance with
Section 2.1.2, which Excite@Home Series B Preferred Stock shall be Escrow Shares
(as defined in Section 2.5); so that as such Unvested Kendara Shares would have
vested if not converted, the Excite@Home Common Stock and the Excite@Home Series
B Preferred Stock will vest, provided that such Excite@Home Series B Preferred
Stock shall remain Escrow Shares.  The certificates representing such shares of
Excite@Home Common Stock and Excite@Home Preferred Stock shall accordingly be
marked with appropriate legends noting such repurchase options or other
conditions.  Kendara shall take all actions that may be necessary to ensure
that, from and after the Effective Time, Excite@Home is entitled to exercise any
such repurchase option or other right set forth in any such restricted stock
purchase agreement or other agreement (other than a right of first refusal).

<PAGE>

     2.2  Adjustments for Capital Changes.  Notwithstanding the provisions of
          -------------------------------
Section 2.1, if Excite@Home recapitalizes, either through a subdivision (or
stock split) of any of its outstanding shares of Excite@Home Common Stock into a
greater number of such shares, or a combination (or reverse stock split) of any
of its outstanding shares of Excite@Home Common Stock into a lesser number of
such shares, or reorganizes, reclassifies or otherwise changes its outstanding
shares of Excite@Home Common Stock into the same or a different number of shares
of other classes or series of Excite@Home stock (other than through a
subdivision or combination of shares provided for in the preceding clause), or
declares a dividend or other distribution on its outstanding shares payable in
shares of Excite@Home Common Stock, in shares or securities convertible into
shares of Excite@Home Common Stock and/or other Excite@Home equity securities
(each, a "Capital Change"), at any time after the Agreement Date and prior to
the Effective Time, then the Excite@Home Average Price Per Share and the Common
Stock Conversion Number will be proportionally and equitably adjusted.

     2.3  Kendara Options.  At the Effective Time, all outstanding options
          ---------------
(collectively, "Kendara Options") to purchase Kendara Common Stock, including
all Kendara Options granted under Kendara's 1999 Stock Plan (the "Kendara Plan")
and the Permitted Non-Dilutive Options, will be assumed by Excite@Home and
Kendara's repurchase right with respect to any unvested shares of Kendara Common
Stock acquired upon the exercise of Kendara Options shall be assigned to
Excite@Home.  Each Kendara Option so assumed by Excite@Home shall be entitled,
in accordance with the terms of such option, to purchase after the Effective
Time that number of shares of Excite@Home Common Stock, determined by
multiplying (a) the number of shares of Kendara Common Stock subject to such
Kendara Option at the Effective Time by (b) the Common Stock Conversion Number,
and the exercise price per share for each such assumed Option will equal the
exercise price of the Kendara Option immediately prior to the Effective Time
divided by the Common Stock Conversion Number.  If the foregoing calculation
results in an assumed option being exercisable for a fraction of a share, then
the number of shares of Excite@Home Common Stock subject to such option will be
rounded down to the nearest whole number and the exercise price of such option
will be rounded up to the nearest cent.  The term, exercisability, vesting
schedule, status as an "incentive stock option" under Section 422A of the Code,
if applicable, and all other terms of the Kendara Options will otherwise be
unchanged.  Continuous employment with Kendara will be credited to an optionee
for purposes of determining the number of shares that are vested after the
Effective Time.  Excite@Home will cause the Excite@Home Common Stock issued upon
exercise of the assumed Kendara Options to be registered on Form S-8 of the
Securities and Exchange Commission ("SEC") as soon as is practicable after the
Effective Time (but no later than fifteen whole business days after the
Effective Time), and will exercise reasonable commercial efforts to maintain the
effectiveness of such registration statement for so long as such assumed Kendara
Options remain outstanding and will reserve a sufficient number of shares of
Excite@Home Common Stock for issuance upon exercise thereof.  Excite@Home will
administer the Kendara Plan assumed pursuant to this Section 2.3 in a manner
that complies with Rule 16b-3 promulgated by the SEC under the Securities
Exchange Act of 1934, as amended ("Exchange Act").

     2.4  Kendara Warrants.  At the Effective Time, all then outstanding
          ----------------
warrants, exchangeable or convertible securities or rights to purchase or
otherwise acquire, that are

                                      -7-
<PAGE>

exercisable or convertible, ultimately or potentially, into any Kendara Common
Stock (each, a "Kendara Warrant") shall by virtue of the Merger, and without any
further action on the part of any holder thereof, be assumed by Excite@Home and
converted into a warrant or like security (each, a "Excite@Home Warrant") to
purchase that number of shares of Excite@Home Common Stock determined by
multiplying (a) the number of shares of Kendara Common Stock that are subject to
such Kendara Warrant immediately prior to the Effective Time by (b) the Common
Stock Conversion Number, at an exercise price per share of such Excite@Home
Common Stock equal to the exercise price per share of Kendara Common Stock that
was in effect for such Kendara Warrant immediately prior to the Effective Time
divided by the Common Stock Conversion Number. If the foregoing calculation
would result in an assumed Kendara Warrant being exercisable (a) for a fraction
of a share of Excite@Home Common Stock, then the number of shares of Excite@Home
Common Stock subject to such Excite@Home Warrant will be rounded down to the
nearest whole number of shares of Excite@Home Common Stock, or (b) for a
fraction of a cent, then the exercise price of such Kendara Warrant will be
rounded up to the nearest cent. The exercisability period and other terms and
conditions of the Kendara Warrants will remain unchanged.

     2.5  Escrow of Shares.  At the Effective Time, Excite@Home will withhold
          ----------------
from the shares of Excite@Home Common Stock, Excite@Home Series B Preferred
Stock and Excite@Home Series C Preferred Stock to be issued to Kendara
Stockholders in the Merger upon conversion of their Kendara Common Stock
pursuant to Section 2.1.2 above, all of the shares of Excite@Home Series B
Preferred Stock and the Escrow Excite@Home Series C Preferred Stock (as defined
below) issued to such Kendara Stockholders pursuant to Section 2.1.2 (such
withheld shares of Excite@Home Preferred Stock and any shares of Excite@Home
capital stock or other securities into which such shares of Excite@Home
Preferred Stock are converted or exchanged and any dividends or distributions
received in respect of such shares of Excite@Home Preferred Stock or other stock
or securities to which such shares of Excite@Home Preferred Stock are converted
or exchanged, being hereinafter referred to as the "Escrow Shares"), and will
hold the certificates representing such Escrow Shares as security for the
Kendara Stockholders' indemnification obligations for Damages (as defined in
Section 11.2) under Article 11 hereof.  The Escrow Shares will be represented by
a certificate or certificates issued in the names of each Kendara Stockholder in
proportion to each such stockholder's interest therein and will be held by
Excite@Home, subject to the terms and conditions of Article 11 hereof, until the
Release Date (as defined in Section 11.1 hereof).  "Escrow Excite@Home Series C
Preferred Stock" shall mean twenty percent of the Excite@Home Series C Preferred
Stock issued to Kendara Founders that vest or as to which Kendara's repurchase
option lapses on or prior to the first anniversary of the Effective Time
pursuant to the terms of an Amended Restricted Stock Purchase Agreement between
each Kendara Founder and Kendara in the form and substance attached hereto as
Exhibit F.

     3.5  No Conflict.  Neither the execution and delivery of this Agreement
          -----------
nor any of the Kendara Ancillary Agreements by Kendara, nor the consummation of

waiver or approval of any third party (including the consent of any party

breach or violation of any such agreement following the Merger), other than the
approval of this Agreement and the Merger by Kendara Stockholders under Delaware

following the Effective Time, any Kendara Material Agreement will continue to be

     3.13  Intellectual Property.
           ---------------------

     3.13.1  Kendara owns, or has the valid right or license to use, possess,
sell, license, copy, distribute, market, advertise and/or dispose of all
Intellectual Property (as defined below) to the extent necessary or required for
the conduct of the Kendara Business (as defined below) (such Intellectual
Property being hereinafter collectively referred to as the "Kendara IP Rights"),
and such rights to use, possess, sell, license, copy, distribute, market,
advertise and/or dispose of are sufficient for such conduct of such business. As
used herein, the term "Kendara Business" means the business of Kendara as
presently conducted, presently proposed to be conducted, and as previously
proposed to be conducted (but only with respect to the relevance engine and
display technology, commonly referred to as the Kendara Assistant, for
previously proposed to be conducted business). As used herein, the term
"Intellectual Property" means, collectively, all worldwide industrial and
intellectual property rights, including, without limitation, patents, patent
applications, patent rights, trademarks, trademark registrations and
applications therefor, trade dress rights, trade names, service marks, service
mark registrations and applications therefor, Internet domain names, Internet
and World Wide Web URLs or addresses, copyrights, copyright registrations and
applications therefor, mask work rights, mask work registrations and
applications therefor, franchises, licenses, inventions, trade secrets, know-
how, customer lists, supplier lists, proprietary processes and formulae,
software source code and object code, algorithms, net lists, architectures,
structures, screen displays, photographs, images, layouts, inventions,
development tools, designs, blueprints, specifications, technical drawings (or
similar information in electronic format) and all documentation and media
constituting, describing or relating to the foregoing, including, without
limitation, manuals, programmers' notes, memoranda and records. As used in this
Section 13, "Kendara-Owned IP Rights" means Kendara IP Rights which are owned or
exclusively licensed to Kendara; and "Kendara-Licensed IP Rights" means Kendara
IP Rights which are not Kendara-Owned IP Rights. By way of clarification, if a
vendor grants certain license rights to Kendara, only the license rights granted

                                      -21-
<PAGE>

by the vendor to Kendara is included under the term Kendara-Licensed IP Rights
and Kendara IP Rights.

     3.13.2  Neither the execution, delivery and performance of this Agreement,
the Certificate of Merger, or the consummation of the Merger and the other
transactions contemplated by this Agreement and/or by Kendara Ancillary
Agreements will, in accordance with their terms: (a) constitute a material
breach of or default under any instrument, contract, license or other agreement
governing any Kendara IP Right to which Kendara is a party (collectively, the
"Kendara IP Rights Agreements"); (b) cause the forfeiture or termination of, or
give rise to a right of forfeiture or termination of, any Kendara IP Right; or
(c) materially impair the right of Kendara or the Surviving Corporation to use,
possess, sell or license any Kendara IP Right or portion thereof. There are no
royalties, honoraria, fees or other payments payable by Kendara to any third
person (other than salaries payable to employees and independent contractors not
contingent on or related to use of their work product) as a result of the
ownership, use, possession, license-in, sale, marketing, advertising or
disposition of any Kendara IP Rights by Kendara to the extent necessary for the
conduct of the Kendara Business and none will become payable as a result of the
consummation of the transactions contemplated by this Agreement, in and of
themselves, except for per copy license fees of less than $500 for software
generally commercially available to the public.

     3.13.3  Neither the manufacture, marketing, license, sale, furnishing
or intended use of any product or service currently licensed, utilized, sold,
provided or furnished by Kendara or currently under development by Kendara
violates any license or agreement between Kendara and any third party or
infringes or misappropriates any Intellectual Property Right of any other party;
and there is no pending or threatened, claim or litigation contesting the
validity, ownership or right of Kendara to exercise any Kendara IP Right nor, to
the best knowledge of Kendara, is there any legitimate basis for any such claim,
nor has Kendara received any notice asserting that any Kendara IP Right or the
proposed use, sale, license or disposition thereof conflicts or will conflict
with the rights of any other party, nor, to the best knowledge of Kendara, is
there any legitimate basis for any such assertion.

     3.13.4  No current or former employee, consultant or independent contractor
of Kendara: (a) is in material violation of any term or covenant of any
employment contract, patent disclosure agreement, invention assignment
agreement, non-disclosure agreement, noncompetition agreement or any other
contract or agreement with any other party by virtue of such employee's,
consultant's, or independent contractor's being employed by, or performing
services for, Kendara or using trade secrets or proprietary information of
others without permission that would be likely to have a Material Adverse Effect
on Kendara; or (b) has developed any technology, software or other
copyrightable, patentable, or otherwise proprietary work for Kendara that is
subject to any agreement under which such employee, consultant or independent
contractor has assigned or otherwise granted to any third party any rights
(including without limitation Intellectual Property) in or to such technology,
software or other copyrightable, patentable or otherwise proprietary work. The
employment of any employee of Kendara or the use by Kendara of the services of
any consultant or independent contractor does not subject Kendara to any
liability to any third party for improperly soliciting such employee or

                                      -22-
<PAGE>

consultant, or independent contractor to work for Kendara, whether such
liability is based on contractual or other legal obligations to such third
party.

     3.13.5  Kendara has taken reasonably necessary and appropriate steps to
protect, preserve and maintain the secrecy and confidentiality of the Kendara IP
Rights (in the case of Kendara-Licensed IP Rights, to the extent required by
such third parties) and to preserve and maintain all Kendara's interests and
proprietary rights in Kendara IP Rights. All officers, employees and consultants
of Kendara having access to proprietary information of Kendara, its customers or
business partners and inventions owned by Kendara, have executed and delivered
to Kendara an agreement regarding the protection of such proprietary information
and the assignment of Kendara's inventions to Kendara (in the case of
proprietary information of Kendara's customer and business partners, to the
extent required by such customers and business partners); and copies of all such
agreements have been delivered to Excite@Home's counsel. Kendara has secured
valid written assignments from all of Kendara's consultants, contractors and
employees who were involved in, or who contributed to, the creation or
development of any Kendara-Owned IP Rights, of the rights to such contributions
that may be owned by such persons or that Kendara does not already own by
operation of law. No current or former employee, officer, director, consultant
or independent contractor of Kendara has any right, license, claim or interest
whatsoever in or with respect to any Kendara IP Rights.

     3.13.6  Item 3.13.6 to the Kendara Disclosure Letter contains a true and
             -----------
complete list of (i) all worldwide registrations made by or on behalf of Kendara
of any patents, copyrights, mask works, trademarks, service marks, Internet
domain names or Internet or World Wide Web URLs or addresses with any
governmental or quasi-governmental authority; and (ii) all applications,
registrations, filings and other formal written governmental actions made or
taken pursuant to federal, state and foreign laws by Kendara to secure, perfect
or protect its interest in Kendara IP Rights, including, without limitation, all
patent applications, copyright applications, and applications for registration
of trademarks and service marks. All registered patents, trademarks, service
marks, Internet domain names, Internet or World Wide Web URLs or addresses, and
copyrights held by Kendara are valid, enforceable and subsisting.

     3.13.7  Kendara owns all right, title and interest in and to all
Kendara-Owned IP Rights free and clear of all security interests, liens,
pledges, mortgages, assignments, claims, licenses, restrictions and encumbrances
(other than licenses and rights listed in Item 3.13.8). Kendara's right, license
and interest in and to all Kendara-Licensed IP Rights are free and clear of all
security interests, liens, pledges, mortgages, assignments, claims, licenses,
and encumbrances (other than licenses and rights listed in Item 3.13.8).

     3.13.8  Item 3.13.8 to the Kendara Disclosure Letter contains a true and
             -----------
complete list of (i) all licenses, sublicenses and other agreements as to which

use any Kendara IP Rights, and (ii) all licenses, sublicenses and other
agreements as to which Kendara is a party and pursuant to which Kendara is
authorized to use any third party patents, trademarks, Internet domain names,
Internet or World Wide Web URLs or addresses, or copyrights, including but not
limited to software.

     3.13.9   Neither Kendara nor any other party acting on behalf, has
disclosed or delivered to any party, or permitted the disclosure or delivery to
any escrow agent or other party, of any Kendara Source Code (as defined below).
No event has occurred, and no circumstance or condition exists, that (with or
without notice or lapse of time) will, or would reasonably be expected to,
result in the disclosure or delivery by Kendara or any other party acting on
Kendara's behalf to any party of any Kendara Source Code (as defined below).
Item 3.13.9 of the Kendara Disclosure Letter identifies each contract, agreement
-----------
and instrument (whether written or oral) pursuant to which Kendara has
deposited, or is or may be required to deposit, with an escrowholder or any
other party, any Kendara Source Code and further describes whether the execution
of this Agreement or the consummation of the Merger or any of the other
transactions contemplated by this Agreement, in and of itself, would reasonably
be expected to result in the release from escrow of any Kendara Source Code. As
used in this Section 3.13.9, "Kendara Source Code" means, collectively, any
software source code, or any material portion or aspect of the software source
code, or any material proprietary information or algorithm contained in or
relating to any software source code, of any Kendara-Owned IP Rights or any
other product marketed or currently proposed to be marketed by Kendara.

          3.13.10  There is no unauthorized use, disclosure, infringement or
misappropriation of any Kendara IP Rights by any third party, including any
employee or former employee of Kendara.  Kendara has not agreed to indemnify any
person for any infringement of any Intellectual Property of any third party by
any product or service that has been sold, licensed to third parties, leased to
third parties, supplied, marketed, distributed, or provided by Kendara.

     3.13.11  To Kendara's knowledge, all software developed by Kendara and
licensed by Kendara to customers and all other products manufactured, sold,
licensed, leased or delivered by Kendara to customers and all services provided
by Kendara to customers on or prior to the Closing Date conform in all material
respects (to the extent required in contracts with such customers) to applicable
contractual commitments, express and implied warranties, product specifications
and product documentation and to any representations provided to customers and
Kendara has no material liability (and, to Kendara's knowledge, there is no
legitimate basis for any present or future action, suit, proceeding, hearing,
investigation, charge, complaint, claim or demand against Kendara giving rise to
any material liability relating to the foregoing contracts that could have a
Material Adverse Effect on Kendara) for replacement or repair thereof or other
damages in connection therewith in excess of any reserves therefor reflected on
the Balance Sheet.

     3.13.12  All of the software, hardware or other technology developed,
owned, licensed and/or marketed or distributed by Kendara to the extent
necessary for the conduct of the Kendara Business are Year 2000 Compliant. "Year
2000 Compliant" means, to the extent related to date-related errors, as applied
to software, hardware or other technology, that: (i) such software, hardware or
other technology will operate and correctly store, represent and process
(including sort) all dates (including single and multi-century formulas and leap
year calculations), such that date-related errors will not occur when the date
being used is in the Year 2000, or in a year preceding or following the Year
2000; (ii) such software, hardware or other technology has been written and
tested to support numeric and date transitions from the twentieth century to the

                                      -24-
<PAGE>

twenty-first century, and back (including without limitation all calculations,
aging, reporting, printing, displays, reversals, disaster and vital records
recoveries) without date-related error, corruption or impact to current and/or
future operations; and (iii) such software, hardware or other technology will
function without error or interruption related to any date information,
specifically including errors or interruptions from functions which may involve
date information from more than one century.   Notwithstanding anything to the
contrary, the foregoing applies only if such software, hardware or other
technology receive properly formatted data.

     No government funding; facilities of a university, college, other
educational institution or research center; or funding from third parties (other
than funds received in consideration for capital stock of Kendara) was used in
the development of the computer software programs or applications owned by the
Company.  No current or former employee, consultant or independent contractor of
Kendara, who was involved in, or who contributed to, the creation or development
of any Kendara IP Rights, has performed services for the government, university,
college, or other educational institution or research center during a period of
time during which such employee, consultant or independent contractor was also
performing services for Kendara.

at all times made all disclosures to users or customers required by Applicable
Law and none of such disclosures made or contained in any such materials have

Kendara.

     3.14.3  Kendara holds all material permits, licenses and approvals from,
and has made all material filings with, government (and quasi-governmental)
agencies and authorities, that are necessary for Kendara to conduct its present

all such Governmental Permits are in full force and effect. Kendara has not
received any notice or other communication from any Governmental Authority
regarding (a) any actual or possible violation of law or any Governmental Permit
or any failure to comply with any term or requirement of any Governmental

of Excite@Home Common Stock and Excite@Home Preferred Stock into which such
shares of Kendara Common Stock will have been converted pursuant to Section
2.1.2, subject to the provisions of Section 2.1.4 (regarding the elimination of

("Dissenting Shares") shall not be converted into a right to receive Excite@Home
Common Stock or Excite@Home Preferred Stock, but shall be converted into the
right to receive such consideration as may be determined to be due with respect
to such Dissenting Shares pursuant to the DGCL. Kendara shall give Excite@Home
prompt notice (and in no event more than two business days) of any demand
received by Kendara for appraisal of Kendara Common Stock, and Excite@Home shall
have the right to control all negotiations and proceedings with respect to such
demand. Kendara agrees that, except with the prior written consent of
Excite@Home, it will not voluntarily make any payment with respect to, or settle
or offer to settle, any such demand for appraisal. In the event that any Kendara
Stockholder fails to make an effective demand for payment or otherwise loses his
status as a holder of Dissenting Shares (a "Dissenting Stockholder"),
Excite@Home shall, as of the later of the Effective Time of the Merger or ten
business days from the occurrence of such event, issue and deliver, upon
surrender by such Dissenting Stockholder of its Kendara Certificate or
Certificates, the shares of Excite@Home Common Stock and Excite@Home Preferred
Stock and any cash payment in lieu of fractional shares, in each case without
interest thereon, to which such Dissenting Shareholder would have been entitled
to under Section 2.1.2 of this Agreement (less the number of shares of
Excite@Home Common Stock and Excite@Home Preferred Stock to be held in escrow
with respect to such stockholder pursuant to Section 2.5).

<PAGE>

          (b)  Each Kendara Stockholder severally (and not jointly) indemnifies
and holds harmless Excite@Home Indemnified Persons from and against all Damages
incurred or suffered by any such persons or arising from, by reason of or in
connection with (i) any misrepresentation or breach of or default in connection
with any of the representations, warranties, covenants or agreements given or
made by such Kendara Stockholder in the Investment Representation Letter
executed by such Kendara Stockholder pursuant to this Agreement, (ii) the
failure of any Kendara Stockholder to have full right, capacity and authority to

     11.3  Limitation.
           ----------

          (a)  Cap On Indemnity Obligation.  Except with respect to claims for
               ---------------------------
indemnification for Founder Special Damages, Non-Founder Special Damages and
Stockholder Damages, the Escrow Shares shall constitute the sole and exclusive
remedy of Excite@Home and the Surviving Corporation with respect to Damages. In
seeking indemnification for Damages under Section 11.2, the Excite@Home
Indemnified Persons shall first exercise their remedies with respect to the
Escrow Shares and any other assets deposited in escrow pursuant to the terms of
Section 2.5 and Article 11 hereof (including any shares of Excite@Home capital
stock or other securities into which Excite@Home Preferred Stock is converted or
exchanged or which is received in respect of such shares of Excite@Home
Preferred Stock or other capital stock and securities), and then, solely with
respect to Founder Special Damages, Non-Founder Special Damages and Stockholder
Damages, may seek recovery of such Damages against any other assets of the
Kendara Stockholder or the Kendara Founders (as the case may be). The value of
each share of Excite@Home Preferred Stock shall, for such purposes of satisfying
claims for Damages, be deemed to equal 1,000 times the Excite@Home Average Price
Per Share, regardless of its actual fair market value as of the time that a
claim for indemnification

                                      -52-
<PAGE>

may be made against such share. Each Kendara Stockholder agrees that claims for
indemnification against such person under this Article 11 may be satisfied by
the forfeiture of such person's shares of Excite@Home Preferred Stock (including
fractions of a share thereof) as provided for in this Article 11 and that no
Excite@Home Indemnified Person shall have any obligation to exercise its
remedies against any other assets of such Kendara Stockholder prior to
exercising them against such shares of Excite@Home Preferred Stock. In the event
of a Capital Change after the Effective Time, the Excite@Home Average Price Per
Share will, for purposes of this Section 11.3, be proportionally and equitably
adjusted. Notwithstanding the foregoing, in no event shall any claim for Founder
Special Damages, Non-Founder Special Damages and Stockholder Damages against any
Kendara Stockholder exceed the value of the Excite@Home securities received by
such Kendara Stockholder in the Merger.

          (b)  Basket.  The indemnification provided for in Section 11.2(a)
               ------
shall not apply unless and until the aggregate Damages for which one or more
Excite@Home Indemnified Persons seeks or has sought indemnification hereunder
exceeds a cumulative aggregate of $100,000 (the "Basket"), in which event
Kendara Stockholders shall, subject to the other limitations herein, be liable
to indemnify the Excite@Home Indemnified Persons for all Damages; provided,
however, that the Basket and the foregoing provisions of this sentence shall not
apply to any indemnification claim for fraudulent conduct or fraudulent
misrepresentation on the part of Kendara or a Kendara Stockholder.

     11.4 Appointment of Representative.  By voting in favor of the Merger,
          -----------------------------
each of the Kendara Stockholders approves the designation of and designates
Timothy M. Haley as the Representative of the Kendara Stockholders and as the
attorney-in-fact and agent for and on behalf of each Kendara Stockholder with
respect to claims for indemnification under Article 11 and the taking by the
Representative of any and all actions and the making of any decisions required
or permitted to be taken by the Representative under this Agreement, including,
without limitation, the exercise of the power to:  (a) authorize the release or
delivery to Excite@Home of shares of Excite@Home Preferred Stock and any other
assets deposited in escrow pursuant to the terms of Section 2.5 and Article 11
hereof (including any shares of Excite@Home capital stock or other securities
into which Excite@Home Preferred Stock is converted or exchanged or which is
received in respect of such shares of Excite@Home Preferred Stock or other
capital stock and securities) in satisfaction of indemnity claims by Excite@Home
or any other Excite@Home Indemnified Person (as defined herein) pursuant to
Article 11; (b) agree to, negotiate, enter into settlements and compromises of,
demand arbitration of, and comply with orders of courts and awards of
arbitrators with respect to, such claims; (c) arbitrate, resolve, settle or
compromise any claim for indemnity made pursuant to Article 11; and (d) take all
actions necessary in the judgment of the Representative for the accomplishment
of the foregoing.  The Representative will have authority and power to act on
behalf of each Kendara Stockholder with respect to the disposition, settlement
or other handling of all claims under Article 11 hereof and all rights or
obligations arising under Article 11.  The Kendara Stockholders will be bound by
all actions taken and documents executed by the Representative in connection
with Article 11, and Excite@Home will be entitled to rely on any action or
decision of the Representative.  In performing the functions specified in this
Agreement, the Representative will not be liable to any Kendara Stockholder in
the absence of gross negligence or willful misconduct on the part of the

                                      -53-
<PAGE>

Representative.  The Kendara Stockholders shall severally indemnify the
Representative and hold him harmless against any loss, liability or expense
incurred without gross negligence or willful misconduct on the part of the
Representative and arising out of or in connection with the acceptance or
administration of his duties hereunder.  Any out-of-pocket costs and expenses
reasonably incurred by the Representative in connection with actions taken by
the Representative pursuant to the terms of Article 11 (including without
limitation the hiring of legal counsel and the incurring of legal fees and
costs) will be paid by the Kendara Stockholders to the Representative pro rata
in proportion to their respective percentage equity interests as reflected in
Schedule 3.4.1(a) to this Agreement, which Kendara Stockholders shall be
entitled to reimbursement by  Excite@Home if Excite@Home is determined to be a
Non-Prevailing Party pursuant to Section 11.8(c)(i) below.

     11.5  Notice of Claim. As used herein, the term "Claim" means a claim for
           ---------------
indemnification of Excite@Home or any other Excite@Home Indemnified Person for
Damages under Article 11.  Excite@Home (and only Excite@Home) may give notice of
a Claim under this Agreement whether for its own Damages or for Damages incurred
by any other Excite@Home Indemnified Person, and Excite@Home will give written
notice of a Claim executed by an officer of Excite@Home (a "Notice of Claim") to
the Representative promptly after Excite@Home becomes aware of the existence of
any potential claim by an Excite@Home Indemnified Person for indemnity from the
Kendara Stockholders or a Kendara Stockholder under Article 11, but in any event
before the Release Date arising from or relating to:

           (a)  (i) any inaccuracy, misrepresentation, breach of, or default in,
any of the representations, warranties or covenants given or made by Kendara in
this Agreement or in the Kendara Disclosure Letter or in any certificate
delivered by Kendara or an officer of Kendara pursuant hereto, (ii) the
incurring of any Excess Transaction Expenses, or (iii) any Stockholder Damages;
or

           (b)  the assertion, whether orally or in writing, against Excite@Home
or against any other Excite@Home Indemnified Person of a claim, demand, suit,
action, arbitration, investigation, inquiry or proceeding brought by a third
party against such Indemnified Person that is based upon, or includes assertions
that would, if true, constitute (in each such case, a "Third-Party Claim"): (i)
any inaccuracy, misrepresentation, breach of, or default in, any of the
representations, warranties or covenants given or made by Kendara in this
Agreement or in the Kendara Disclosure Letter or in any certificate delivered by
or on behalf of Kendara or an officer of Kendara pursuant hereto (if such
inaccuracy, misrepresentation, breach or default existed at the Closing Date),
(ii) any Excess Transaction Expenses, or (iii) any Stockholder Damages.

     Until the Release Date, no delay on the part of Excite@Home in giving the
Representative a Notice of Claim will relieve the Representative or any Kendara
Stockholder from any of its obligations under Article 11 unless (and then only
to the extent) that the Representative or the Kendara Stockholders are
materially prejudiced thereby.

     11.6 Defense of Third-Party Claims.
          -----------------------------

          (a)  Excite@Home shall defend any Third-Party Claim, and the costs and
expenses incurred by Excite@Home in connection with such defense (including but
not limited to reasonable attorneys' fees, other professionals' and experts'
fees and court or arbitration costs) shall be included in the Damages for which
Excite@Home may seek indemnity pursuant to a Claim made by any Excite@Home
Indemnified Person hereunder.

          (b)  The Representative shall have the right to receive copies of all
pleadings, notices and communications with respect to the Third-Party Claim to
the extent that receipt of such documents by the Representative does not affect
any privilege relating to the Excite@Home Indemnified Person, and may
participate in settlement negotiations with respect to the Third-Party Claim. No
Excite@Home Indemnified Person shall enter into any settlement of a Third-Party
Claim without the prior written consent of the Representative (which consent
shall not be unreasonably withheld), provided, that if the Representative shall
have consented in writing to any such settlement, then the Representative shall
have no power or authority to object to any Claim by any Excite@Home Indemnified
Person for indemnity under Section 11.2 hereof for the amount of such
settlement; and the Kendara Stockholders will remain responsible to indemnify
the Excite@Home Indemnified Persons for all Damages they may incur arising out
of, resulting from or caused by the Third-Party Claim to the fullest extent
provided in Article 11 hereof.

     11.7 Contents of Notice of Claim.  Each Notice of Claim by Excite@Home
          ---------------------------
given pursuant to Section 11.5 will contain the following information:

          (a) that Excite@Home has incurred, paid or properly accrued (in
accordance with GAAP) or, in good faith, believes it will have to incur, pay or
accrue (in accordance with GAAP), Damages in an aggregate stated amount arising
from such Claim (which amount may be the amount of damages claimed by a third
party in an action brought against any Excite@Home Indemnified Person based on
alleged facts, which if true, would give rise to liability for Damages to such
Excite@Home Indemnified Person under Article 11); and

          (b) a brief description, in reasonable detail (to the extent
reasonably available to Excite@Home), of the facts, circumstances or events
giving rise to the alleged Damages based on Excite@Home's good faith belief
thereof, including, without limitation, the identity and address of any third-
party claimant (to the extent reasonably available to Excite@Home) and copies of
any formal demand or complaint, the amount of Damages, the date each such item
was incurred, paid or properly accrued, or the basis for such anticipated
liability, and the specific nature of the breach to which such item is related.

     11.8 Resolution of Notice of Claim.  Any Notice of Claim received by the
          -----------------------------
Representative pursuant to Section 11.5 and Section 11.7 above will be resolved
as follows:

          (a)  Uncontested Claims. In the event that, within forty-five calendar
               ------------------
days after a Notice of Claim is received by the Representative pursuant to
Section 11.5 and Section 11.7, the Representative does not contest such Notice
of Claim in writing to Excite@Home as provided in Section 11.8(b) (an
"Uncontested Claim"), the Representative will be conclusively

                                      -55-
<PAGE>

deemed to have consented, on behalf of all Kendara Stockholders or a Kendara
Stockholder (in the case of a claim for Stockholder Damages), to the recovery by
the Excite@Home Indemnified Person of the full amount of Damages specified in
the Notice of Claim in accordance with this Article 11, including the forfeiture
of shares of Excite@Home Preferred Stock and any other assets deposited in
escrow pursuant to the terms of Section 2.5 and Article 11 hereof (including any
shares of Excite@Home capital stock or other securities into which Excite@Home
Preferred Stock is converted or exchanged or which is received in respect of
such shares of Excite@Home Preferred Stock or other capital stock and
securities), in accordance with Section 11.3(a) and, without further notice, to
have stipulated to the entry of a final judgment for damages against the Kendara
Stockholders or a Kendara Stockholder (in the case of a claim for Stockholder
Damages) for such amount in any court having jurisdiction over the matter where
venue is proper.

          (b)  Contested Claims. In the event that the Representative gives
               ----------------
Excite@Home written notice contesting all or any portion of a Notice of Claim (a
"Contested Claim") within the forty-five day period specified in Section
11.8(a), then: (i) such Contested Claim will be resolved by either (A) a written
settlement agreement executed by Excite@Home and the Representative or (B) in
the absence of such a written settlement agreement, by binding arbitration
between Excite@Home and the Representative in accordance with the terms and
provisions of Section 11.8(c).

          (c)  Arbitration of Contested Claims. Each of Excite@Home, Kendara and
               -------------------------------
the Kendara Stockholders agree that any Contested Claim will be submitted to
mandatory, final and binding arbitration before J.A.M.S./ENDISPUTE or its
successor ("J.A.M.S."), pursuant to the United States Arbitration Act, 9 U.S.C.,
Section 1 et seq. and that any such arbitration will be conducted in San Mateo
County, California. Either Excite@Home or the Representative may commence the
arbitration process called for by this Agreement by filing a written demand for
arbitration with J.A.M.S. and giving a copy of such demand to each of the other
parties to this Agreement. The arbitration will be conducted in accordance with
the provisions of J.A.M.S' Streamlined Arbitration Rules and Procedures in
effect at the time of filing of the demand for arbitration, subject to the
provisions of Section 11.8(c) of this Agreement. The parties will cooperate with
J.A.M.S. and with each other in promptly selecting an arbitrator from J.A.M.S.'
panel of neutrals, and in scheduling the arbitration proceedings in order to
fulfill the provisions, purposes and intent of this Agreement. The parties
covenant that they will participate in the arbitration in good faith, and that
they will share in its costs in accordance with subparagraph (i) below. The
provisions of this Section 11.8(c) may be enforced by any court of competent
jurisdiction, and the party seeking enforcement will be entitled to an award of
all costs, fees and expenses, including attorneys' fees, to be paid by the party
against whom enforcement is ordered. Subject to the provisions of subparagraph
(vii) below, judgment upon the award rendered by the arbitrator may be entered
in any court having competent jurisdiction.

                         (i)  Payment of Costs.  Excite@Home on the one hand,
                              ----------------
and Kendara Stockholders or a Kendara Stockholder (in the case of a claim for
Stockholder Damages) (through the Representative), on the other hand, will bear
the expense of deposits and advances required by the arbitrator in equal
proportions, but either party may advance such

                                      -56-
<PAGE>

amounts, subject to recovery as an addition or offset to any award. The
arbitrator shall determine the party who is the Prevailing Party and the party
who is the Non-Prevailing Party. The Non-Prevailing Party shall pay all
reasonable costs, fees and expenses related to the arbitration, including
reasonable fees and expenses of attorneys, accountants and other professionals
incurred by the prevailing party, the fees of each arbitrator and the
administrative fee of the arbitration proceedings. If such an award would result
in manifest injustice, however, the arbitrator may apportion such costs, fees
and expenses between the parties in such a manner as the arbitrator deems just
and equitable.

                         (ii)  Burden of Proof.  Except as may be otherwise
                               ---------------
expressly provided herein, for any Contested Claim submitted to arbitration, the
burden of proof will be as it would be if the claim were litigated in a judicial
proceeding governed by California law exclusively.

                         (iii) Award.  Upon the conclusion of any arbitration
                               -----
proceedings hereunder, the arbitrator will render findings of fact and
conclusions of law and a final written arbitration award setting forth the basis
and reasons for any decision reached (the "Final Award") and will deliver such
documents to the Representative and Excite@Home, together with a signed copy of
the Final Award. Subject to the provisions of subparagraph (vii) below, the
Final Award will constitute a conclusive determination of all issues in
question, binding upon the Kendara Stockholders or a Kendara Stockholder (in the
case of a claim for Stockholder Damages), the Representative and Excite@Home,
and will include an affirmative statement to such effect.

                         (iv)  Timing.  The Representative, Excite@Home and the
                               ------
arbitrator will conclude each arbitration pursuant to this Section 11.8 as
promptly as possible for the Contested Claim being arbitrated.

                         (v)   Terms of Arbitration. The arbitrator chosen in
                               --------------------
accordance with these provisions will not have the power to alter, amend or
otherwise affect the terms of these arbitration provisions or the provisions of
this Agreement.

                         (vi) Exclusive Remedy.  Following the Effective Time,
                              ----------------
except as specifically otherwise provided in this Agreement, arbitration
conducted in accordance with this Agreement will be the sole and exclusive
remedy of the parties for any Claim made pursuant to Article 11.

     11.9  Distribution Upon Termination of Escrow Period  Within ten business
           ----------------------------------------------
days following the Release Date, Excite@Home shall deliver to the Kendara
Stockholders all of the Escrow Shares in excess of any amount of Escrow Shares
necessary to satisfy any unsatisfied or disputed claims for Damages specified in
any Notice of Claim delivered to the Representative before the Release Date. As
soon as all such claims have been resolved, Excite@Home shall deliver to the
Kendara Stockholders all remaining Escrow Shares not required to satisfy such
claims.

     12.2 Form S-3 Shelf Registration.
          ---------------------------

          (a)  Filing and Registration Period. Subject to the terms and
               ------------------------------
conditions of this Agreement, as promptly as practicable following the Effective
Time of the Merger but no later than fifteen whole business days thereafter, and
consistent with the requirements of applicable law, Excite@Home shall prepare
and file with the SEC a registration statement on Form S-3 for an offering to be
made on a continuous basis pursuant to Rule 415 covering all of the then
outstanding Registrable Securities (the "Shelf Registration"). Excite@Home shall
use commercially reasonable efforts to have such Shelf Registration declared
effective as soon as practicable after its filing and to keep the Shelf
Registration continuously effective under the Securities Act for a continuous
period of time (such period of time being hereinafter called the "Registration
Period") commencing on the date the Shelf Registration is declared effective
under the Securities Act by the SEC (the "Date of Effectiveness") and ending on
the date that is the first anniversary of the Effective Time of the Merger.
Excite@Home shall have no duty or obligation to keep the Shelf Registration (or
any Subsequent Registration, as defined below) effective after the expiration of
the Registration Period. Excite@Home shall have no duty or obligation to keep
the Shelf Registration effective after the expiration of the Shelf Registration
Period.

          (b)  Subsequent Registration.  If the Shelf Registration is filed with
               -----------------------
the SEC and becomes effective under the Securities Act, and the Shelf
Registration or a Subsequent Registration (as defined below) thereafter ceases
to be effective for any reason at any time during the Registration Period, then
Excite@Home shall use all reasonable efforts to obtain the prompt withdrawal of
any order suspending the effectiveness thereof, and in any event shall, within
thirty days of such cessation of effectiveness, file an amendment to the Shelf
Registration seeking to obtain the withdrawal of the order suspending the
effectiveness thereof, or file an additional "shelf" registration statement
pursuant to Rule 415 covering all of the then outstanding Registrable Securities
(a "Subsequent Registration"). If a Subsequent Registration is filed,
Excite@Home shall use its best efforts to cause the Subsequent Registration to
be declared effective as soon as practicable after such filing and to keep such
registration statement continuously effective until the end of the Registration
Period.

               --------------------------
12.2(g), during the Registration Period Excite@Home shall supplement and amend
the Shelf Registration or Subsequent Registration, as applicable, if, as and
when required by the Securities Act, the rules and regulations promulgated
thereunder or the rules, regulations or instructions applicable to the
registration form used by Excite@Home for such Shelf Registration.

          (d)  Timing and Manner of Sales. Any sale of Registrable Securities
               --------------------------
pursuant to a Shelf Registration or a Subsequent Registration under this Section
12.2 may be made only during a "Permitted Window" (as defined in Section 12.2(g)
below). In addition, any sale of Registrable Securities pursuant to a Shelf
Registration or a Subsequent Registration under this Section 12.2 may only be
made in accordance with the method or methods of distribution of such
Registrable Securities that are described in the registration statement for the
Shelf Registration (or Subsequent Registration, as applicable) and permitted by
such form of registration statement,

                                      -59-
<PAGE>

which methods of distribution will be specified by the Holders in their Notice
of Resale (as defined below). Subject to any other agreements between the Holder
and Excite@Home or Surviving Corporation, notwithstanding the terms and
conditions of this Section 12, a Holder may also sell Registrable Securities in
a bona fide private offering if the selling Holder provides Excite@Home with a
written opinion of counsel, satisfactory to counsel to Excite@Home acting in a
reasonable manner, that such offer and sale is an exempt transaction under the
Securities Act and applicable state securities laws, complies with all
requirements for such exemptions and is not made with use of the prospectus for
the Shelf Registration (or Subsequent Registration, if applicable).

          (e)  No Underwritings.  No sale of Registrable Securities under any
               ----------------
Shelf Registration (or Subsequent Registration) effected pursuant to this
Section 12.2 may be effected pursuant to any underwritten offering without
Excite@Home's prior written consent, which may be withheld in its sole and
absolute discretion.

          (f)  Notice of Resale.  Before any Holder may make any sale, transfer
               ----------------
or other disposition of any Registrable Securities under the Shelf Registration
(or a Subsequent Registration) during the Registration Period, a Holder who own
at least five percent of the Registrable Securities then outstanding must first
give written notice to Excite@Home (a "Notice of Resale") of such Holder's
present intention to so sell, transfer or otherwise dispose of some or all of
such Holder's Registrable Securities, and the number of Registrable Securities
such Holder propose(s) to so sell, transfer or otherwise dispose of. In
addition, a Notice of Resale shall contain the information required to be
included therein under Section 12.2(g).

          (g)  Permitted Window; Sale Procedures.
               ---------------------------------

               (i)   A "Permitted Window" is a period of thirty consecutive
trading days commencing upon Excite@Home's written notification to the Kendara
Stockholders in response to a Notice of Resale that the prospectus contained in
the Form S-3 registration statement filed pursuant to Section 12.2 of this
Agreement is available to be used for resales of Registrable Securities pursuant
to the Shelf Registration (or a Subsequent Registration, as applicable).

               (ii)  Before a Holder can make a sale of any Registrable
Securities pursuant to the Shelf Registration (or a Subsequent Registration),
and in order to cause a Permitted Window to commence, such Holder must first
give Excite@Home a Notice of Resale indicating such Holder's intention to sell
Registrable Securities pursuant to the Shelf Registration (or Subsequent
Registration, as applicable) and such Holder's intended plan of distribution of
such Registrable Securities (which must conform to the plan of distribution
contained in the prospectus for the Shelf Registration (or Subsequent
Registration, as applicable)).

               (iii) Upon receipt of such Notice of Resale (unless a certificate
of Excite@Home is delivered as provided in Section 12.3(b) below), Excite@Home
will give written notice to all Holders as soon as practicable, but in no event
more than three business days after Excite@Home's receipt of such Notice of
Resale that either:  (A) the prospectus contained in the registration statement
for the Shelf Registration (or Subsequent Registration, if applicable)

                                      -60-
<PAGE>

is current (it being acknowledged that it may be necessary for Excite@Home to
supplement the prospectus or make an appropriate filing under the Exchange Act
so as to cause the prospectus to become current) and that (as applicable) the
Permitted Window will commence on the date of such notice by Excite@Home; or (B)
Excite@Home is required under the Securities Act and the regulations thereunder
to amend the registration statement for the Shelf Registration (or Subsequent
Registration, as applicable) in order to cause the prospectus to be current. In
the event that Excite@Home determines that an amendment to the registration
statement is necessary as provided above, it will use all commercially
reasonable efforts to file and cause such amendment to become effective as soon
as practicable; whereupon it will notify the Holders that the Permitted Window
will then commence.

                    (iv) Excite@Home shall not be obligated to keep the
registration statement for the Shelf Registration (or any Subsequent
Registration) current during any period other than a Permitted Window. The
Holders may elect to withdraw a request for registration pursuant to a Notice of
Resale; provided however, that if Excite@Home has commenced preparation of any
supplement or amendment to the registration statement or any part thereof in
response to such Notice of Resale prior to receiving written notice from the
Holders' of the withdrawal of their request for registration, then the Holders
who originally gave Excite@Home such Notice of Resale will promptly reimburse
Excite@Home for its actual costs and expenses incurred in preparing and/or
filing such supplement and/or amendment.

               (h)  Trading Window Compliance. The Holders acknowledge that the
                    -------------------------
Excite@Home Insider Trading Compliance Program and Insider Trading Policy, as
such may be amended from time to time, a current copy of which has been provided
to Kendara prior to the Closing (the "Excite@Home Trading Policy") requires that
those directors, officers and employees of Excite@Home and its subsidiaries and
those other persons whom Excite@Home determines to be "Access Personnel" or
otherwise subject to the "trading window" and pre-clearance requirements of the
Excite@Home Trading Policy (and members of their immediate families and
households) are permitted to effect trades in Excite@Home securities: (i) only
during those specified time periods ("trading windows") in which such persons
are permitted to make sales, purchases or other trades in Excite@Home's
securities under the "trading window" provisions of the Excite@Home Trading
Policy; and (ii) only after pre-clearance of such sales, purchases or other
trades with Excite@Home's Insider Trading Compliance Officer. If a Holder is or
becomes subject to the "trading window" and/or "pre-clearance" provisions of the
Excite@Home Trading Policy described above, then, notwithstanding anything
herein to the contrary, such Holder may sell, transfer and dispose of
Registrable Securities only during those trading windows during which such
Excite@Home Access Personnel are permitted to effect trades in Excite@Home stock
under the Excite@Home Trading Policy and only after pre-clearing such trades
with Excite@Home's Insider Trading Compliance Officer as provided in the
Excite@Home Trading Policy.

     12.3 Limitations.  Notwithstanding the provisions of Section 12.2 above,
          -----------
Excite@Home shall not be obligated to effect any registration, qualification or
compliance of Registrable Securities pursuant to Section 12.2 of this Agreement,
and the Holders shall not be

                                      -61-
<PAGE>

entitled to sell Registrable Securities pursuant to any registration statement
filed under Section 12.2 of this Agreement, as applicable:

          (a)  if Form S-3 is not then available for such offering by the
Holders;

          (b)  if Excite@Home shall furnish to the Holders (and all other
holders of Excite@Home's registrable securities) a certificate signed by an
officer of Excite@Home stating that, in the good faith judgment of such officer,
it would be detrimental to Excite@Home and its stockholders for such Permitted
Window to be in effect at such time, due, for example, to the existence of a
material development or potential material development involving Excite@Home
which Excite@Home would be obligated to disclose in the prospectus contained in
the Shelf Registration (or Subsequent Registration, as applicable), which
disclosure would, in the good faith judgment of such officer, be premature or
otherwise inadvisable at such time or would have a material adverse affect upon
Excite@Home and its stockholders, in which event Excite@Home will have the right
to defer a Permitted Window for a period of not more than forty days after
receipt of a Notice of Resale from the Holder or Holders pursuant to this
Section 12.3(b), provided that in the event that a Permitted Window is deferred
by Excite@Home pursuant to this Section 12.3(b) then Excite@Home shall extend
the Registration Period hereunder by the number of days that such Permitted
Window was so deferred;

          (c)  if Excite@Home is acquired and Excite@Home Common Stock ceases to
be publicly traded;

          (d)  in any particular jurisdiction in which Excite@Home would be
required to qualify to do business or to execute a general consent to service of
process in effecting such registration, qualification or compliance, unless
Excite@Home is already subject to service of process in such jurisdiction; or

          (e)  if the SEC refuses to declare such registration effective due to
the participation of any particular Holder in such registration (unless such
Holder withdraws all such Holder's Registrable Securities from such registration
statement); or if the manner in which any Registrable Securities are disposed of
pursuant to the Shelf Registration (or Subsequent Registration, as applicable)
is not included within the plan of distribution set forth in the prospectus for
the Shelf Registration (or Subsequent Registration, as applicable).

     12.4 Shares Otherwise Eligible for Resale.  Notwithstanding anything herein
          ------------------------------------
to the contrary, Excite@Home shall not be obligated to effect or continue to
keep effective any such registration, registration statement, qualification or
compliance with respect to the Registrable Securities held by any particular
Holder:

          (a)  if Excite@Home or its legal counsel shall have received a "no-
action" letter or similar written confirmation from the SEC that all the
Registrable Securities then held by such Holder may be resold by such Holder
within a three month period without registration under the Securities Act
pursuant to the provisions of Rule 144 promulgated under the Securities Act (or
successor provisions), or otherwise;

                                      -62-
<PAGE>

          (b)  if legal counsel to Excite@Home shall deliver a written opinion
to Excite@Home, its transfer agent and the Holders, in form and substance
reasonably acceptable to Excite@Home to the effect that all the Registrable
Securities then held by such Holder may be resold by such Holder within a three
month period without registration under the Securities Act pursuant to the
provisions of Rule 144 promulgated under the Securities Act, or otherwise; or

          (c)  after expiration or termination of the Registration Period.

     12.5 Expenses.  Excite@Home shall pay all expenses incurred in connection
          --------
with any registration effected by Excite@Home pursuant to this Agreement
(excluding brokers' discounts and commissions), including, without limitation,
all filing, registration and qualification, printers', legal (including, the
reasonable fees and expenses of one counsel for the Holders as a group) and
accounting fees.

     12.6 Obligations of Excite@Home.  Subject to Sections 12.2, 12.3 and 12.4
          --------------------------
above, when required to effect the registration of any Registrable Securities
under the terms of this Agreement, Excite@Home will, as expeditiously as
reasonably possible:

          (a)  furnish to the Holders such number of copies of the prospectus
for the Shelf Registration (or Subsequent Registration, as applicable),
including a preliminary prospectus (and amendments or supplements thereto), in
conformity with the requirements of the Securities Act, and such other documents
as they may reasonably request in order to facilitate the disposition of the
Registrable Securities owned by them;

          (b)  notify each Holder of Registrable Securities promptly and, if
requested by such Holder, confirm such notification in writing promptly (i) when
a registration statement has become effective and when any post-effective
amendments and supplements thereto become effective, (ii) of any request the SEC
or any state securities authority for post-effective amendments and supplements
to a registration statement has become effective, (iii) of the issuance by the
SEC or any state securities authority of any stop order suspending the
effectiveness of a registration statement or the initiation of any proceedings
for that purpose, (iv) of the receipt by Excite@Home of any notification with
respect to the suspension of the qualification of the Registrable Securities for
sale in any jurisdiction or the initiation or threatening of any proceeding for
such purpose, and (v) of any determination by Excite@Home that a post-effective
amendment to a registration statement would be appropriate;

          (c)  use all reasonable efforts to (i) register and qualify the
securities covered by such registration statement under such other securities or
blue sky laws of such jurisdictions in the United States as will be reasonably
requested by the Holders; provided that Excite@Home will not be required in
connection therewith or as a condition thereto to qualify to do business or to
file a general consent to service of process in any such state or jurisdiction
unless Excite@Home is already so qualified or subject to service of process,
respectively, in such jurisdiction; and (ii) cause such Registrable Securities
to be registered with or approved by such other governmental agencies or
authorities, including the National Association of Securities Dealers as may be
necessary by virtue of the business and operations of Excite@Home; provided that
Excite@Home will not be required to (A) qualify generally to do business in any
jurisdiction

                                      -63-
<PAGE>

where it would not otherwise be required to qualify but for this paragraph (c),
(B) subject itself to taxation in any jurisdiction, or (C) consent to general
service of process in any such jurisdiction except as may be required by the
Securities Act;

          (d)  promptly notify each Holder of Registrable Securities covered by
such registration statement, at any time during a Permitted Window when a
prospectus relating thereto is required to be delivered under the Securities
Act, of the happening of any event as a result of which the prospectus included
in such registration statement, as then in effect, includes an untrue statement
of a material fact or omits to state a material fact required to be stated
therein or necessary to make the statements therein not misleading in the light
of the circumstances then existing and, subject to the provisions of this
Agreement, at the request of any Holder, prepare and furnish to each Holder of
Registrable Securities then outstanding a reasonable number of copies of a
supplement to or an amendment of the prospectus as may be necessary to correct
the untrue statement or omission;

          (e)  make available for inspection by any Holder of Registrable
Securities and any attorney, accountant or other professional retained by any
such Holder (collectively, the "Inspectors"), all financial and other records,
pertinent corporate documents and properties of Excite@Home (collectively, the
"Records") as shall be reasonably necessary to enable them to exercise their due
diligence responsibility, and cause Excite@Home's officers, directors and
employees to supply all information reasonably requested by any Inspectors in
connection with such registration statement; provided, that prior to any such
disclosure, such Inspector executes a non-disclosure agreement in form and
substance acceptable to Excite@Home. Records which Excite@Home determines, in
good faith, to be confidential and which it notifies the Inspectors in writing
are confidential shall not be disclosed to the Inspectors unless (i) the
disclosure of such Records is necessary to avoid or correct a misstatement or
omission in such registration statement or (ii) the release of such Records is
ordered pursuant to a subpoena or other order from a court of competent
jurisdiction. Each Holder of Registrable Securities agrees that information
obtained by it as a result of such inspections shall be deemed confidential and
shall not be used by it as the basis for any market transactions in the
securities of Excite@Home or its affiliates or otherwise disclosed by it unless
and until such is made generally available to the public. Each Holder of such
Registrable Securities further agrees that it will, upon leaning that disclosure
of such Records is sought in a court of competent jurisdiction, give written
notice to Excite@Home and allow Excite@Home, at its expense, to undertake
appropriate action to prevent disclosure of the Records deemed confidential;

          (f)  use its commercially reasonable efforts to cause all such
Registrable Securities to be listed on the Nasdaq National Market and each
securities exchange on which similar securities issued by Excite@Home are then
listed; and

          (g)  upon the request of any Holder, promptly provide the name,
address and other contract information regarding Excite@Home's transfer agent
for the Registrable Securities and the CUSIP number for the Registrable
Securities.

                                      -64-

     12.7  Furnish Information.  It shall be a condition precedent to the
           -------------------
obligations of Excite@Home to take any action pursuant to this Article 12 that
the selling Holders will furnish to Excite@Home such information regarding
themselves, the Registrable Securities held by them, and the intended method of
disposition and plan of distribution of such Registrable Securities as shall be
required to timely effect the registration of their Registrable Securities.

     12.8  Delay of Registration.  No Holder will have any right to obtain or
           ---------------------
seek an injunction restraining or otherwise delaying any registration that is
the subject of this Agreement as the result of any controversy that might arise
with respect to the interpretation or implementation of this Agreement.

     12.9  Indemnification.
           ---------------

           (a)  By Excite@Home.  To the extent permitted by law, Excite@Home
                --------------
will indemnify, defend and hold harmless each Holder against any losses, claims,
damages, or liabilities (joint or several) to which such Holder may become
subject under the Securities Act, the Exchange Act or other U.S. federal or
state law, insofar as such losses, claims, damages, or liabilities (or actions
in respect thereof) arise out of or are based upon any of the following
statements, omissions or violations (collectively, a "Violation"):

                (i)  any untrue statement or alleged untrue statement of a
material fact contained in a registration statement filed by Excite@Home
pursuant to this Agreement pursuant to which Registrable Securities are sold,
including any preliminary prospectus or final prospectus contained therein or
any amendments or supplements thereto;

                (ii) the omission or alleged omission to state in such
registration statement, preliminary prospectus or final prospectus or any
amendments or supplements thereto, a material fact required to be stated
therein, or necessary to make the statements therein not misleading; or

               (iii) any violation or alleged violation by Excite@Home of the
Securities Act, the Exchange Act, any U.S. federal or state securities law or
any rule or regulation promulgated under the Securities Act, the Exchange Act or
any U.S. federal or state securities law in connection with the offering of
Registrable Securities covered by such registration statement;

provided however, that the indemnity agreement contained in this subsection
12.9(a) shall not apply to amounts paid in settlement of any such loss, claim,
damage, liability or action if such settlement is effected without the written
consent of Excite@Home (which consent shall not be unreasonably withheld), nor
shall Excite@Home be liable in any such case for any such loss, claim, damage,
liability or action to the extent that it arises out of or is based upon a
Violation which occurs in reliance upon and in conformity with written
information furnished expressly for use in connection with such registration by
such Holder.

          (b)  By Selling Holders.  To the extent permitted by law, (i) each
               ------------------
selling Holder will indemnify and hold harmless Excite@Home, each of its
directors, each of its officers

                                      -65-
<PAGE>

who have signed the registration statement, each Person, if any, who controls
Excite@Home within the meaning of the Securities Act, any underwriter and any
other Holder selling securities under such registration statement, against any
losses, claims, damages or liabilities (joint or several) to which Excite@Home
or any such director, officer, controlling person, underwriter or other such
Holder may become subject under the Securities, the Exchange Act or other
federal or state law, insofar as such losses, claims, damages or liabilities (or
actions in respect thereto) arise out of or are based upon any Violation, in
each case to the extent (and only to the extent) that such Violation occurs in
reliance upon and in conformity with written information furnished by such
Holder expressly for use in connection with such registration; (ii) and each
such Holder will indemnify and reimburse Excite@Home or any such director,
officer, controlling person, underwriter or other Holder for any reasonable
attorneys' fees and other expenses reasonably incurred by Excite@Home or any
such director, officer, controlling person, underwriter or other Holder in
connection with investigating or defending any such loss, claim, damage,
liability or action, as incurred. Each selling Holder's liability pursuant to
this Section 12.9(b) shall be limited to an amount equal to the net proceeds
received by such selling Holder pursuant to sales under the registration
statement.

          (c)  Notice.  Promptly after receipt by an indemnified party under
               ------
this Section 12.9 of notice of the commencement of any action (including any
governmental action) against such indemnified party, such indemnified party
will, if a claim for indemnification or contribution in respect thereof is to be
made against any indemnifying party under this Section 12.9, deliver to the
indemnifying party a written notice of the commencement thereof and, if the
indemnifying party is Excite@Home, Excite@Home shall have the right and
obligation to control the defense of such action, and if Excite@Home fails to
defend such action it shall indemnify and reimburse the selling Holders for any
reasonable attorneys' fees and other expenses reasonably incurred by them in
connection with investigating or defending such action; provided, however, that:
(i) Excite@Home shall also have the right, at its option, to assume and control
the defense of any action with respect to which Excite@Home or any person
entitled to be indemnified by the selling Holders under Section 12.9(b) is
entitled to indemnification from the selling Holders; (ii) the indemnified party
or parties shall have the right to participate at its own expense in the defense
of such action and (but only to the extent agreed in writing with Excite@Home
and any other indemnifying party similarly noticed) to assume the defense
thereof with counsel mutually satisfactory to the parties; and (iii) an
indemnified party shall have the right to retain its own counsel, with the fees
and expenses of such counsel to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to an actual or potential conflict
of interests between such indemnified party and any other party represented by
such counsel in such proceeding. The failure of an indemnified party to deliver
written notice to the indemnifying party within a reasonable time of the
commencement of any such action, if prejudicial to the ability of the
indemnifying party to defend such action, shall relieve such indemnifying party
of any liability to the indemnified party under this Section 12.9, but the
omission so to deliver written notice to the indemnifying party will not relieve
the indemnifying party of any liability that it may have to any indemnified
party otherwise than under this Section 12.9.

                                      -66-
<PAGE>

           (d)  Defect Eliminated in Final Prospectus. The foregoing indemnity
                -------------------------------------
agreements of Excite@Home and the Holders are subject to the condition that,
insofar as they relate to any Violation made in a preliminary prospectus but
eliminated or remedied in the amended or supplemented prospectus on file with
the SEC and effective at the time the sale of Registrable Securities under such
registration statement occurs (the "Amended Prospectus"), such indemnity
agreement shall not inure to the benefit of any person if a copy of the Amended
Prospectus was furnished to the indemnified party and was not furnished to the
person asserting the loss, liability, claim or damage in the action giving rise
to indemnity claims under this Section 12.9, at or prior to the time such action
is required by the Securities Act.

           (e)  Survival.  The obligations of Excite@Home and Holders under this
                --------
Section 12.9 shall survive the completion of any offering of Registrable
Securities in a registration statement pursuant to this Agreement, and
otherwise.

     12.10 Duration and Termination of Excite@Home's Obligations. Excite@Home
           -----------------------------------------------------
will have no obligations pursuant to Section 12.2 of this Agreement with respect
to any Notice of Resale or other request or requests for registration (or
inclusion in a registration) made by any Holder or to maintain or continue to
keep effective any registration or registration statement pursuant hereto: (a)
after the expiration or termination of the Registration Period; (b) with respect
to a particular Holder if, in the opinion of counsel to Excite@Home, all such
Registrable Securities proposed to be sold by such Holder may be sold in a three
(3) month period without registration under the Securities pursuant to Rule 144
promulgated under the Securities or otherwise; or (c) if all Registrable
Securities have been registered and sold pursuant to a registration effected
pursuant to this Agreement and/or have been transferred in transactions in which
registration rights hereunder have not been assigned in accordance with this
Agreement.

     12.11  Acknowledgment of Other Agreements. The Holders acknowledge that
            ----------------------------------
they have been informed by Excite@Home that other stockholders of Excite@Home
currently hold certain Form S-3 and other registration rights that may enable
such other stockholders to sell shares of Excite@Home during one or more
Permitted Windows or at other times (thus potentially adversely affecting the
receptivity of the market to the sale of the Registrable Securities pursuant to
a registration effected pursuant to this Agreement). The Holders further
acknowledge (a) that Excite@Home has agreed not to effect any public sale or
distribution of any of its equity securities or of any security convertible into
or exchangeable or exercisable for any equity security of Excite@Home during the
fourteen days prior to, and during the sixty day period beginning on, the
effective date of any "Demand Registration" (as such term is defined in that
certain Third Amended and Restated Registration Rights Agreement dated as of
April 11, 1997, among Excite@Home and certain holders of Excite@Home capital
stock and attached as Exhibit 4.01 to Excite@Home's Form S-1 filed with the SEC
on May 16, 1997, except as part of such registration, and (b) hereby agree not
to effect any public sale or distribution of any Excite@Home capital stock
during the periods described in clause (a) above, in each case including a sale
pursuant to Rule 144 promulgated under the Securities; provided, that as to each
Holder, Excite@Home shall extend the Registration Period for that number of days
which such Holder of Registrable Securities could have otherwise sold such
securities during a Permitted Window but for the foregoing agreement of the
Holders.

                                      -67-

     12.12  Assignment.  Notwithstanding anything herein to the contrary, the
            ----------
rights of a Holder under Article 12 may be assigned only with Excite@Home's
express prior written consent, which may be withheld in Excite@Home's sole
discretion; provided, however, that the rights of a Holder under Article 12 may
be assigned without Excite@Home's express prior written consent: (a) to a
Permitted Assignee (as defined below); or (b) (if applicable) by will or by the
laws of intestacy, descent or distribution, provided that the assignee first
agrees in writing to be bound by all the obligations of the Holders under this
Article 12. Any attempt to assign any rights of a Holder under Article 12
without Excite@Home's express prior written consent in a situation in which such
consent is required by this Section shall be null and void and without effect.
Subject to the foregoing restrictions, all rights, covenants and agreements in
Article 12 by or on behalf of the parties hereto will bind and inure to the
benefit of the respective permitted successors and assigns of the parties
hereto. Each of the following parties are "Permitted Assignees" for purposes of
this Section 12.12: (a) a trust whose beneficiaries consist solely of a Holder
and such Holder's immediate family; (b) the personal representative (such as an
executor of a Holder's will), custodian or conservator of a Holder, in the case
of the death, bankruptcy or adjudication of incompetency of that Holder; (c)
immediate family members of a Holder; (d) partners of a Holder that is a
partnership; or (e) members of a Holder that is a limited liability company.

                                  ARTICLE 13
                                 Miscellaneous

     13.1  Governing Law.  The internal laws of the State of California,
           -------------
irrespective of its choice of law principles, will govern the validity of this
Agreement, the construction of its terms, and the interpretation and enforcement
of the rights and duties of the parties hereto; provided, however, that issues
involving the consummation and effects of the Merger shall be governed by the
laws of the State of Delaware.

     13.2  Assignment; Binding Upon Successors and Assigns.  Except as set forth
           -----------------------------------------------
in Section 12.12, neither party hereto may assign any of its rights or
obligations hereunder without the prior written consent of the other party
hereto. This Agreement will be binding upon and inure to the benefit of the
parties hereto and their respective successors and permitted assigns. Any
assignment in violation of this provision shall be void.

     13.3  Severability.  If any provision of this Agreement, or the application
           ------------
thereof, will for any reason and to any extent be invalid or unenforceable, then
the remainder of this Agreement 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 the void or unenforceable provision.

     13.4  Counterparts.  This Agreement may be executed in any number of
           ------------
counterparts, each of which will be an original as regards any party whose
signature appears thereon and all of which together will constitute one and the
same instrument.  This Agreement will become

                                      -68-
<PAGE>

binding when one or more counterparts hereof, individually or taken together,
will bear the signatures of all parties reflected hereon as signatories.

     13.5  Other Remedies.  Except as otherwise provided herein, any and all
           --------------
remedies herein expressly conferred upon a party hereunder will be deemed
cumulative with and not exclusive of any other remedy conferred hereby or by law
on such party, and the exercise of any one remedy will not preclude the exercise
of any other. Excite@Home and Kendara agree that the indemnification and
arbitration provisions set forth in Article 11 shall be each such person's sole
and exclusive remedy with respect to any inaccuracy, misrepresentation, breach
of, or default in, any of the representations, warranties, covenants or
agreements of any such party in this Agreement, other than claims for Founder
Special Damages, Non-Founder Special Damages and Stockholder Damages; provided,
that the foregoing shall not limit the parties' respective rights to seek
specific performance or other injunctive relief. 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 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.

     13.6  Amendment and Waivers.  Any term or provision of this Agreement may
           ---------------------
be amended, and the observance of any term of this Agreement may be waived
(either generally or in a particular instance and either retroactively or
prospectively) only by a writing signed by the party to be bound thereby. The
waiver by a party of any breach hereof or default in the performance hereof will
not be deemed to constitute a waiver of any other default or any succeeding
breach or default. This Agreement may be amended by the parties hereto as
provided in this Section at any time before or after approval of this Agreement
by the Kendara Stockholders, but, after such approval, no amendment will be made
which by applicable law requires the further approval of the Kendara
Stockholders without obtaining such further approval. At any time prior to the
Effective Time, each of Kendara and Excite@Home, by action taken by its Board of
Directors, may, to the extent legally allowed, (i) extend the time for the
performance of any of the obligations or other acts of the other; (ii) waive any
inaccuracies in the representations and warranties made to it contained herein
or in any document delivered pursuant hereto; and (iii) waive compliance with
any of the agreements or conditions for its benefit contained herein. No such
waiver or extension will be effective unless signed in writing by the party
against whom such waiver or extension is asserted. The failure of any party to
enforce any of the provisions hereof will not be construed to be a waiver of the
right of such party thereafter to enforce such provisions.

     13.7  Expenses.  Each party will bear its respective legal, auditors',
           --------
investment bankers' and financial advisors' fees and other expenses incurred
with respect to this Agreement, the Merger and the transactions contemplated
hereby ("Transaction Expenses"), except that Kendara shall pay any Transaction
Expenses of the Kendara Stockholders.  Notwithstanding the foregoing, if the
Merger is successfully consummated, then any Transaction Expenses of Kendara not
paid on or prior to the Closing may be paid by Excite@Home and Excite@Home will
thereafter be entitled to indemnification from the Escrow Shares in accordance
with Section

                                      -69-
<PAGE>

11.2 for an amount equal to the amount of such Transaction Expenses (such
amount, "Excess Transaction Expenses"), and such indemnification shall not be
subject to the Basket.

     13.8  Attorneys' Fees.  Should suit be brought to enforce or interpret any
           ---------------
part of this Agreement, the prevailing party will be entitled to recover, as an
element of the costs of suit and not as damages, reasonable attorneys' fees to
be fixed by the court (including without limitation, costs, expenses and fees on
any appeal). The prevailing party will be entitled to recover its costs of suit,
regardless of whether such suit proceeds to final judgment.

     13.9  Notices.  All notices and other communications required or permitted
           -------
under this Agreement will be in writing and will be either hand delivered in
person, sent by facsimile, sent by certified or registered first class mail,
postage pre-paid, or sent by nationally recognized express courier service. Such
notices and other communications will be effective upon receipt if hand
delivered or sent by facsimile, five days after mailing if sent by mail, and one
day after dispatch if sent by express courier, to the following addresses, or
such other addresses as any party may notify the other parties in accordance
with this Section:

     13.10 Construction of Agreement.  This Agreement has been negotiated by the
           -------------------------
respective parties hereto and their attorneys and the language hereof will not
be construed for or against either party.  A reference to a Section or an
exhibit will mean a Section in, or exhibit to, this Agreement unless otherwise
explicitly set forth.  The titles and headings herein are for reference purposes
only and will not in any manner limit the construction of this Agreement which
will be considered as a whole.  Unless otherwise indicated, the words "include,"
"includes" and "including" when used herein shall be deemed in each case to be
followed by the words "without limitation."  Each reference herein to a law,
statute, regulation, document or agreement shall be deemed in each case to
include all amendments thereto.

     13.11 No Joint Venture.  Nothing contained in this Agreement will be deemed
           ----------------
or construed as creating a joint venture or partnership between any of the
parties hereto. No party is by virtue of this Agreement authorized as an agent,
employee or legal representative of any other party. No party will have the
power to control the activities and operations of any other and their status is,
and at all times will continue to be, that of independent contractors with
respect to each other. No party will have any power or authority to bind or
commit any other party. No party will hold itself out as having any authority or

     13.13  Third Party Beneficiary Rights.  No provisions of this Agreement are
            ------------------------------
intended, nor will be interpreted, to provide or create any third party
beneficiary rights or any other rights of any kind in any client, customer,
affiliate, stockholder, partner or any party hereto or any other person or
entity unless specifically provided otherwise herein and, except as so provided,
all provisions hereof will be personal solely between the parties to this
Agreement; except that the provisions of Article 12 are intended to create third
party beneficiary rights for the Kendara Stockholders.

     13.14  Public Announcement.  Upon execution of this Agreement, Excite@Home
            -------------------
and Kendara will issue a press release approved by both parties announcing the
Merger. Thereafter, Excite@Home may issue such press releases, and make such
other disclosures regarding the Merger, as it determines are required under
applicable securities laws or regulatory rules. Prior to the publication of such
initial and mutually agreed press release, neither party will make any public
announcement relating to this Agreement or the transactions contemplated hereby
(except as may be required by law) and Kendara will use its reasonable efforts
to prevent any trading in Excite@Home Common Stock by its officers, directors,
employees, stockholders and agents. Neither Excite@Home nor Kendara will make
any disclosures regarding this Agreement or the Merger that would jeopardize
Excite@Home's ability to timely and lawfully issue the shares of Excite@Home
Common Stock and Excite@Home Preferred Stock in the Merger pursuant to the
exemptions described in Section 2.7.

     13.15  Disclosure Letter.  The Kendara Disclosure Letter shall be arranged

in separate parts corresponding to the numbered and lettered sections contained
in Article 3, and the information disclosed in any numbered or lettered part

or warranty set forth in the corresponding numbered or lettered section in
Article 3, and shall not be deemed to relate to or to qualify any other
representation or warranty.

     13.16  Confidentiality.  Kendara and Excite@Home each confirm that they
            ---------------
have entered into the Confidentiality Agreement and that they are each bound by,
and will abide by, the provisions of such Confidentiality Agreement (except that
Excite@Home will cease to be bound by the Confidentiality Agreement after the
Merger becomes effective). If this Agreement is terminated, the Confidentiality
Agreement shall remain in full force and effect and all copies of documents
containing confidential information of a disclosing party will be returned by
the receiving party to the disclosing party or be destroyed, as provided in the
Confidentiality Agreement.

     13.17  Entire Agreement. This Agreement and the exhibits hereto constitute
            ----------------
the entire understanding and agreement of the parties hereto with respect to the
subject matter hereof and supersede all prior and contemporaneous agreements or
understandings, inducements or conditions, express or implied, written or oral,
between the parties with respect hereto other than the Confidentiality
Agreement. The express terms hereof control and supersede any course of
performance or usage of the trade inconsistent with any of the terms hereof.
