incorporation and the merger agreement and the merger and believes it is in the

                     QUESTIONS AND ANSWERS ABOUT THE MERGER

Q:  WHAT IS THE MERGER?

     A:  In the merger, iMALL will become a wholly-owned subsidiary of
         Excite@Home.

         Based on the capitalization of Excite@Home as of September 20, the
         former stockholders of iMALL will receive in the merger a number of
         shares of Excite@Home Series A common stock representing 2.4% of
         Excite@Home's outstanding common stock and 1.4% of the voting power of
         Excite@Home's outstanding common stock.

         For a more complete description of the merger, see the section entitled
         "The Merger" on page 29.

Q:  WHAT WILL iMALL STOCKHOLDERS RECEIVE IN THE MERGER?

     A:  iMALL stockholders will receive 0.46 (the "exchange ratio") of a share
         of Excite@Home Series A common stock for each share of iMALL common
         stock they own. iMALL stockholders will receive cash based on the
         market price of Excite@Home Series A common stock instead of any
         fractional share.

         For example, a holder of 100 shares of iMALL common stock will receive
         46 shares of Excite@Home Series A common stock.

         Holders of options or warrants to purchase shares of iMALL common stock
         will hold options or warrants, as appropriate, to purchase shares of
         Excite@Home Series A common stock after completion of the merger.

         The number of shares of Excite@Home Series A common stock to be issued
         for each share of iMALL common stock is fixed and will not be adjusted
         based upon changes in the value of these shares. As a result, the value
         of the shares iMALL stockholders will receive in the merger will not be
         known prior to the time of the merger and may go up or down as the
         market price of Excite@Home Series A common stock goes up or down.
         iMALL is not permitted to terminate its obligations to complete the
         merger or resolicit the vote of its stockholders based solely on
         changes in the market price of Excite@Home Series A common stock.

         Excite@Home's stock price is volatile. As an example, the following
         table sets forth, as of the end of the month for each of the last 12
         calendar months, the closing sale price per share of Excite@Home Series
         A common stock on the Nasdaq National Market. This table also reflects
         the value to be received in the merger for each share of iMALL common
         stock, calculated by multiplying the closing price per share of
         Excite@Home common stock by the exchange ratio.

Q:  DOES THE BOARD OF DIRECTORS OF iMALL RECOMMEND VOTING IN FAVOR OF THE MERGER
    AND THE AMENDMENT TO THE ARTICLES OF INCORPORATION?

     A:  Yes. After careful consideration, iMALL's board of directors
         unanimously recommends that its stockholders vote in favor of the
         merger agreement and the merger as well as the amendment to the
         articles of incorporation.

         For a more complete description of the recommendation of iMALL's board
         of directors, see the sections entitled "iMALL's reasons for the
         merger" on page 31, and "Recommendation of iMALL's board of directors"
         on page 33.

Q:  WHAT DO I NEED TO DO NOW?

     A:  You are urged to read this prospectus/proxy statement carefully,

     A:  You should indicate on your proxy card how you want to vote, and sign

         possible so that your shares will be represented at the special
         meeting. If you fail to return your proxy card or to vote in person at
         the special meeting, the effect will be a vote against the amendment to
         the articles of incorporation and against the merger agreement and the
         merger.

         For a more complete description of voting at the special meeting, see
         the section entitled "Voting of proxies" on page 27.

         written notice of revocation of your proxy or a later-dated, signed
         proxy card before the special meeting.

         For a more complete description of how to change your vote, see the
         section entitled "Revocation of proxies" on page 27.

Q:  IF MY SHARES ARE HELD IN "STREET NAME" BY MY BROKER, WILL MY BROKER VOTE MY
    SHARES FOR ME?

     A:  Your broker will vote your shares only if you provide instructions on
         how to vote by following the information provided to you by your
         broker.

Q:  SHOULD I SEND IN MY iMALL STOCK CERTIFICATES NOW?

     A:  No. After the merger is completed, you will receive written

         Excite@Home stock certificates.

Q:  WHEN DO YOU EXPECT THE MERGER TO BE COMPLETED?

         quarter of 1999.

Q:  WILL I RECOGNIZE A GAIN OR LOSS ON THE TRANSACTION?

     A:  Excite@Home and iMALL expect that if the merger is completed, you will
         not recognize gain or loss for United States federal income tax
         purposes, except that you will recognize gain or loss with respect to
         cash received instead of fractional shares. You are urged to consult
         your own tax advisor to determine your particular tax consequences.

including:

     - the merger agreement and the merger must be approved by iMALL
       stockholders;

       merger will qualify as a tax-free reorganization;

     - the shares of Excite@Home Series A common stock to be issued to iMALL
       stockholders in the merger must have been approved for listing on the
       Nasdaq National Market;

       must be true and correct;

     - the parties must have complied in all material respects with their
       respective agreements in the merger agreement;

condition relating to the agreements with First Data which may not be waived
without First Data's consent, iMALL will consider the facts and circumstances at
that time and make a determination as to whether a resolicitation of proxies
from stockholders is appropriate.

VOTES REQUIRED FOR APPROVAL (PAGES 26 TO 27)

     The holders of a majority of the outstanding shares of iMALL common stock
must approve the merger agreement and the merger. iMALL stockholders are

<PAGE>   14

TERMINATION OF THE MERGER AGREEMENT (PAGES 55 TO 56)

     The merger agreement may be terminated by the parties' mutual consent.

     In addition, subject to qualifications, the merger agreement may be
terminated by either of the parties under any of the following circumstances:

     - if the merger is not completed by March 1, 2000, so long as the
       terminating party did not prevent completion of the merger by breaching
       the merger agreement;

     - if a final governmental injunction or order prohibiting the merger is
       issued and is not appealable;

     - if the iMALL stockholders do not approve the merger agreement at the
       special meeting, however, iMALL may not terminate the agreement if the
       failure to obtain stockholder approval resulted from its breach of the
       merger agreement or the breach of any voting agreement; or

     - if the conditions to completion of the merger would not be satisfied (1)
       because of a breach of an agreement in the merger agreement by the other
       which causes the representations and warranties in the merger agreement
       to become untrue, or (2) because a representation or warranty of the
       other in the merger agreement becomes untrue.

     The merger agreement may be terminated by Excite@Home if any of the
following "triggering events" occurs:

     - iMALL's board fails to unanimously recommend that iMALL stockholders
       approve the merger agreement and the merger;

     - iMALL's board fails to reaffirm its unanimous recommendation of the
       merger upon the request of Excite@Home after a proposal for an
       extraordinary transaction involving iMALL such as a merger or sale of
       significant assets has been publicly announced;

     - iMALL's board approves or publicly recommends a proposal for an
       extraordinary transaction involving iMALL;

     - iMALL enters into a letter of intent or other similar document or
       agreement relating to an extraordinary transaction involving iMALL; or

     - any tender or exchange offer relating to securities of iMALL shall be
       commenced and iMALL shall not have recommended the rejection of that
       tender offer or exchange offer.

TERMINATION FEE (PAGES 56 TO 57)

     If the merger agreement is terminated by Excite@Home because of any of the
triggering events described immediately above, iMALL will be obligated to pay
Excite@Home a termination fee of $2.5 million. If within 15 months following the
termination, an extraordinary transaction, such as a merger or sale of
significant assets, occurs with respect to iMALL, or iMALL enters into an
agreement regarding an extraordinary transaction, iMALL will be obligated to pay
Excite@Home an additional $19.6 million.

     If the merger agreement is terminated because iMALL stockholders do not
approve the merger agreement and the merger, iMALL may be obligated to pay
Excite@Home a termination fee of $22.1 million. For iMALL to become obligated to
pay Excite@Home the $22.1 million termination fee, an extraordinary transaction
of the nature specified in the merger agreement involving iMALL and a party
other than Excite@Home must be publicly proposed before the termination of the
merger agreement and iMALL must enter into an agreement for or complete the
extraordinary transaction within 15 months after termination of the merger
agreement.

NO OTHER NEGOTIATIONS INVOLVING iMALL (PAGES 50 TO 51)

     Until the merger is completed or the merger agreement is terminated, iMALL
has agreed, with limited exceptions, not to directly or indirectly take any
action with respect to an Acquisition Proposal, as defined on page 51 of this
prospectus/proxy statement.

     After iMALL receives an Acquisition Proposal that iMALL's board reasonably
concludes may constitute a Superior Offer, as defined on page 51 of this
prospectus/proxy statement, subject to the conditions specified on pages 50 to
51, iMALL may furnish information or enter into discussions with the person or
group that submitted the Acquisition Proposal.

     iMALL has agreed to promptly inform Excite@Home as to any Acquisition
Proposal, request for nonpublic information or inquiry which iMALL believes
would lead to an Acquisition Proposal. iMALL has agreed to inform Excite@Home of
the status and details of any Acquisition Proposal.

THE VOTING AGREEMENTS (PAGE 58)

     Some iMALL stockholders have entered into voting agreements with
Excite@Home. The voting agreements require these iMALL stockholders to vote all
shares of iMALL common stock beneficially owned by them in favor of the approval
of the merger agreement and the merger and the amendment to the articles of
incorporation. Each of these stockholders, other than First Data, granted
Excite@Home an irrevocable proxy to vote their shares in favor of the amendment
to the articles of incorporation and the merger agreement and the merger.

     The stockholders who entered into the voting agreements collectively held
approximately 41.9% of the outstanding iMALL common stock as of the record date.

     The form of voting agreement is attached to this prospectus/proxy statement
as Annex B, and you are urged to read it in its entirety.

OPINION OF FINANCIAL ADVISOR (PAGES 33 TO 41)

     In deciding to approve the merger agreement and the merger, iMALL's board
considered, among various other factors described below in "iMALL's reasons for
the merger," an opinion from its financial advisor, BancBoston Robertson
Stephens, Inc. On July 11, 1999, BancBoston Robertson Stephens delivered to
iMALL's board its oral opinion, which it subsequently confirmed in writing,
that, as of that date, the exchange ratio in the merger was fair from a
financial point of view to iMALL's stockholders other than Excite@Home or any of
its affiliates.

     The full text of the written opinion of BancBoston Robertson Stephens which
sets forth the assumptions made, matters considered and limitations on the
review undertaken in connection with the opinion, is attached to this
prospectus/proxy statement as Annex C. You should read this opinion in its
entirety. The opinion of BancBoston Robertson Stephens does not constitute a
recommendation as to how any iMALL stockholder should vote with respect to the
merger.

ACCOUNTING TREATMENT OF THE MERGER (PAGE 45)

     Excite@Home intends to account for the merger as a "purchase" for financial
accounting purposes, under U. S. generally accepted accounting principles.

INTERESTS OF CERTAIN PERSONS IN THE MERGER (PAGE 41)

     In considering the recommendation of iMALL's board, you should be aware
that officers and directors of iMALL have interests in the merger that are
different from, or in addition to, those of stockholders generally. These
interests include:

     - some officers of iMALL will become employees of Excite@Home or the
       company resulting from the merger and will have employment agreements;

                                        7
<PAGE>   16

     - iMALL's directors and officers have customary rights to indemnification
       against liabilities;

     - First Data, which as of the record date owned 10.2% of the outstanding
       shares of iMALL common stock, entered into a marketing agreement, an
       amended marketing and development agreement, a capacity reservation
       agreement, and upon completion of the merger, will enter into a
       registration rights agreement with Excite@Home. In addition, if the
       merger is completed, Excite@Home will issue First Data a warrant to
       purchase 2,300,000 shares of its Series A common stock.

APPRAISAL RIGHTS (PAGE 28)

     Under Nevada law, holders of iMALL common stock are not entitled to
appraisal or dissenters' rights in the merger.

ANTITRUST APPROVAL REQUIRED TO COMPLETE THE MERGER (PAGE 45)

the required filings with the Department of Justice and the Federal Trade
Commission. However, the Department of Justice or the Federal Trade Commission,
or government, state or private person, may challenge the merger at any time
before or after its completion.

ABILITY TO SELL EXCITE@HOME STOCK (PAGE 45)

     All shares of Excite@Home Series A common stock received by iMALL
stockholders in connection with the merger will be freely transferable unless

  the printing of this prospectus/proxy statement....    $38.31      $16.81       $17.62
</TABLE>

     The iMALL equivalent price per share is equal to the closing price of a
share of Excite@Home Series A common stock on that date multiplied by 0.46, the
number of shares of Excite@Home Series A common stock to be issued in exchange
for each share of iMALL common stock.

     Excite@Home and iMALL have never paid cash dividends on their respective
shares of common stock. Under the merger agreement, iMALL has agreed not to pay
cash dividends pending the consummation of the merger, without written consent
of Excite@Home. If the merger is not completed, iMALL's board presently intends
that it would continue its policy of retaining any earnings to finance the
expansion of its business. The Excite@Home board presently intends to retain all
earnings for use in its business and has no present intention to pay cash
dividends before or after the merger.

         COMPARATIVE HISTORICAL AND UNAUDITED PRO FORMA PER SHARE DATA

     The following table sets forth (1) the pro forma historical net loss per
share (presented as if the merger between At Home Corporation and Excite, Inc.
had taken place at the beginning of each period presented) and the historical
book value per share data of Excite@Home as disclosed in Excite@Home's Form 10-Q
for the period ended June 30, 1999 and Form 8-K/A dated August 13, 1999
incorporated by reference in this prospectus/proxy statement; (2) historical net
loss per share and historical book value per share data of iMALL; (3) unaudited
pro forma condensed combined net loss per share and unaudited pro forma
condensed combined book value per share data of Excite@Home after giving effect
to the merger; and (4) unaudited equivalent pro forma condensed combined net
loss per share and unaudited equivalent pro forma condensed combined book value
per share data of iMALL based on the exchange ratio of 0.46 of a share of
Excite@Home's Series A common stock for each share of iMALL's common stock. See
"The Merger -- Structure of the merger and conversion of iMALL common stock" on
page 42.

     The information in the table should be read in conjunction with the pro
forma financial statements of Excite@Home and the financial statements of iMALL
and the related notes incorporated by reference in this prospectus/proxy
statement. The unaudited pro forma condensed combined financial information is
not necessarily indicative of the net loss per share or book value per share
that would have been achieved had the merger been consummated as of the
beginning of the periods presented and should not be construed as representative
of these amounts for any future dates or periods.

</TABLE>

- -------------------------

(1) Historical book value per share is computed by dividing pro forma
    stockholders' equity less goodwill and other intangible assets by the number
    of pro forma shares of common stock outstanding at the end of each period.
    Excite@Home's historical net loss per share, which did not include the
    results of operations of Excite, Inc. for periods prior to its merger into
    At Home Corporation in May 1999, was $(1.26) and $(0.89) for the year ended
    December 31, 1998 and for the six months ended June 30, 1999, respectively.

(2) Historical book value per share is computed by dividing stockholders' equity
    less goodwill and other intangible assets by the number of shares of common
    stock outstanding at the end of each period.

(3) The iMALL historical net loss per share data for the year ended December 31,
    1998 and the six months ended June 30, 1999 include a net (loss) and income
    per share for discontinued operations of ($0.26) and $0.01, respectively.

(4) The pro forma condensed combined book value per share is computed by
    dividing pro forma stockholders' equity less goodwill and other intangible
    assets, including the effect of pro forma adjustments for the merger, by the
    pro forma number of shares of Excite@Home Series A common stock which would
    have been outstanding had the merger been consummated as of June 30, 1999.

(5) The iMALL equivalent pro forma condensed combined per share amounts are
    calculated by multiplying the pro forma condensed combined book value per
    share amounts by the exchange ratio of 0.46 of a share of Excite@Home Series
    A common stock for each share of iMALL common stock.

                                  RISK FACTORS

     The merger involves a high degree of risk. Also, by voting in favor of the
merger agreement and the merger, iMALL stockholders will be choosing to invest
in Excite@Home Series A common stock. Any investment in Excite@Home Series A
common stock involves a high degree of risk. In addition to the other
information contained or incorporated by reference in this prospectus/proxy
statement, iMALL stockholders should carefully consider the following risk
factors in deciding whether to vote for the merger agreement and the merger.

RISKS RELATING TO THE PROPOSED MERGER

IMALL STOCKHOLDERS WILL RECEIVE A FIXED RATIO OF 0.46 OF A SHARE OF EXCITE@HOME
SERIES A COMMON STOCK PER IMALL SHARE EVEN IF THERE ARE CHANGES IN THE MARKET
VALUE OF IMALL COMMON STOCK OR EXCITE@HOME SERIES A COMMON STOCK BEFORE THE
COMPLETION OF THE MERGER

     There will be no adjustment to the exchange ratio if the market price of
either iMALL common stock or Excite@Home Series A common stock fluctuates. The
specific dollar value of Excite@Home Series A common stock that iMALL
stockholders will receive upon completion of the merger will depend on the
market price of Excite@Home Series A common stock at the time of the merger. The
share prices of both iMALL common stock and Excite@Home Series A common stock
are subject to price fluctuations in the market for publicly-traded equity
securities and have each experienced significant volatility. Excite@Home and
iMALL cannot predict the market prices for either iMALL common stock or
Excite@Home Series A common stock at any time before the completion of the
merger or the market price for Excite@Home Series A common stock after the
completion of the merger. EXCITE@HOME AND IMALL ENCOURAGE YOU TO OBTAIN CURRENT
MARKET QUOTATIONS FOR THE EXCITE@HOME SERIES A COMMON STOCK AND THE IMALL COMMON
STOCK.

EXCITE@HOME'S PRO FORMA ACCOUNTING FOR THE ACQUISITION MAY CHANGE

     Excite@Home has allocated the total estimated purchase price for the iMALL
acquisition on a preliminary basis to assets and liabilities based on
Excite@Home's best estimates of the fair value of these assets and liabilities,
with the excess costs over the net tangible assets acquired allocated to
goodwill and other intangible assets. This allocation is subject to change
pending a final analysis of the fair values of the assets acquired and
liabilities assumed. The impact of these changes could be material to
Excite@Home's future results of operations.

THERE ARE TECHNICAL, OPERATIONAL AND STRATEGIC CHALLENGES THAT MAY PREVENT
EXCITE@HOME FROM SUCCESSFULLY INTEGRATING IMALL WITH EXCITE@HOME

     The merger involves risks related to the integration and management of
acquired technology, operations and personnel. The integration of Excite@Home
and iMALL will be a complex process and may disrupt the combined company's
business if not completed in a timely and efficient manner. Following the
merger, Excite@Home must operate as a combined organization utilizing common
information and communication systems, operating procedures, financial controls
and human resources practices. Excite@Home may

                                       13
<PAGE>   22

encounter substantial difficulties, costs and delays involved in integrating
iMALL's operations, including:

     - potential incompatibility of business cultures;

     - perceived adverse changes in business focus;

     - potential conflicts in sponsor, advertising or content relationships; and

     - the loss of key employees and diversion of the attention of management
       from other ongoing business concerns.

THE MERGER COULD HARM KEY THIRD PARTY RELATIONSHIPS

     The present and potential relationships of iMALL with sponsors, customers,
advertisers and users may be harmed by the proposed merger. Uncertainties
regarding sponsorship, joint venture overlap and new service development
following the merger may cause these parties to delay decisions regarding these
relationships. Any changes in these relationships could harm the combined
company's business.

IMALL MAY LOSE CONTRACTUAL RIGHTS DUE TO THE MERGER

     iMALL has contracts with suppliers, customers and other business partners.
Some of these contracts require iMALL to obtain the consent, waiver or approval
of these other parties in connection with the proposed merger. If consent,
waiver or approval cannot be obtained, iMALL may lose the right to use
intellectual property or other rights that are necessary for operation of
iMALL's services. iMALL has agreed to attempt to secure the necessary consents,
waivers and approvals. However, iMALL may not be able to obtain all of the
necessary consents, waivers and approvals. Failure to do so could harm the
combined company's business.

OFFICERS AND DIRECTORS OF IMALL HAVE DIFFERENT INTERESTS FROM YOURS AS AN IMALL
STOCKHOLDER

     The directors and officers of iMALL have interests in the merger that are
different from, or are in addition to, those of stockholders generally. These
include:

     - some officers of iMALL will become employees of Excite@Home or the
       company resulting from the merger and will have employment agreements;

     - iMALL's directors and executive officers have customary rights to
       indemnification against liabilities; and

     - First Data entered into a marketing agreement, an amended marketing and
       development agreement, a capacity reservation agreement, and upon
       completion of the merger, will enter into a registration rights agreement
       with Excite@Home. In addition, if the merger is completed, Excite@Home
       will issue First Data a warrant to purchase 2,300,000 shares of its
       Series A common stock.

     As a result, officers and directors could be more likely to vote to approve
the merger agreement and the merger than if they did not hold these interests.

     For a more complete description of these interests see the section entitled
"The Merger -- Interests of certain persons in the merger" on page 41.

RISKS RELATED TO EXCITE@HOME'S BUSINESS

EXCITE@HOME HAS INCURRED AND EXPECTS TO INCUR SUBSTANTIAL LOSSES

     Excite@Home was incorporated in March 1995, commenced operations in August
1995, and has incurred net losses in each fiscal period since its inception. As
of June 30, 1999, Excite@Home had an accumulated deficit of $463.2 million. In
addition, Excite@Home currently intends to increase capital expenditures and
operating expenses in order to expand its network and to market and provide its
services to potential subscribers. As a result, Excite@Home expects to incur
additional net losses before cost and amortization of distribution agreements
and amortization of goodwill and other intangible assets for at least the next
quarter. As a result of the acquisition of Excite and the proposed acquisition
of iMALL, Excite@Home anticipates that it will incur substantial non-cash
charges relating to the amortization of goodwill and other intangible assets.

EXCITE@HOME'S BUSINESS IS UNPROVEN, AND IT MAY NOT ACHIEVE PROFITABILITY

     The profit potential of Excite@Home's business model is unproven. The
Excite@Home service was available only in portions of 89 geographic markets as
of June 30, 1999 and may not achieve broad consumer or commercial acceptance.
Although approximately 3,300 primarily small and medium-sized business
organizations have agreed to utilize @Work services as of June 30, 1999, the
@Work services may not achieve broad commercial acceptance and the current rate
of deployment for @Work services may not be sustained. Excite@Home has
difficulty predicting whether the pricing models for its Internet services will
prove to be viable, whether demand for Excite@Home's Internet services will
materialize at the prices its cable partners charge for the Excite@Home service
or the prices Excite@Home or its cable partners charge for Excite@Home's @Work
services, or whether current or future pricing levels will be sustainable. If
these pricing levels are not achieved or sustained or if Excite@Home's services
do not achieve or sustain broad market acceptance, Excite@Home's business,
operating results and financial condition will be significantly harmed.
Excite@Home may never achieve favorable operating results or profitability.

     Excite@Home's Media services rely substantially upon the sale of
advertising, ad serving and targeting marketing solutions on the Internet, which
is a developing market. Risks related to the Media services business include:

     - the inability to maintain and increase levels of traffic on Excite@Home's
       Internet portal services;

     - the failure of the market to adopt the Internet as an advertising and
       commercial medium;

     - reductions in market prices for Internet advertising as a result of
       competition or otherwise;

     - the inability to achieve higher cost per thousand impression rates for
       targeted advertising or to increase the percentage of advertising
       inventory sold;

     - the inability to meet minimum guaranteed impressions under sponsorship
       agreements;

     - the inability to develop or acquire content for the Media services;

                                       15
<PAGE>   24

     - the inability to generate commerce-related revenues;

     - the inability of the Media services to continue to generate increased
       revenues;

     - the failure to anticipate and adapt to a developing market; and

     - government regulation.

GROWTH OF THE EXCITE@HOME SERVICE MAY BE INHIBITED BY FACTORS BEYOND
EXCITE@HOME'S CONTROL

     As of June 30, 1999, Excite@Home had in excess of 620,000 cable modem
subscribers, including recently acquired Internet subscribers that are being
converted to the Excite@Home service. Excite@Home's ability to increase the
number of subscribers to the Excite@Home service to achieve its business plans
and generate future revenues will depend on many factors which are beyond its
control. For instance, some of Excite@Home's cable partners have not achieved
the subscriber levels that Excite@Home had originally anticipated. Other factors
include:

     - the rate at which Excite@Home's current and future cable partners upgrade
       their cable infrastructures for two-way data services;

     - Excite@Home's ability and the ability of its cable partners to coordinate
       timely and effective marketing campaigns with the availability of cable
       infrastructure upgrades;

     - the success of Excite@Home's cable partners in marketing and installing
       the @Home service in their local cable areas;

     - the prices that Excite@Home's cable partners set for the @Home service
       and for its installation;

     - the speed at which Excite@Home's cable partners can complete the
       installations required to initiate service for new subscribers;

     - the commercial availability of self-installable, two-way modems that
       comply with the recently adopted interface standards known as DOCSIS, and
       the success of Excite@Home's roll-out of these products with the @Home
       service;.

     - the quality of customer and technical support provided by Excite@Home and
       its cable partners; and

     - the quality of content on the @Home service.

EXCITE@HOME NEEDS TO ADD SUBSCRIBERS AT A RAPID RATE FOR ITS BUSINESS TO
SUCCEED, BUT EXCITE@HOME MAY NOT ACHIEVE ITS SUBSCRIBER GROWTH GOALS

     Excite@Home's actual revenues or the rate at which it will add new
subscribers may differ from its forecasts. Excite@Home may not be able to
increase its subscriber base enough to meet its internal forecasts or the
forecasts of industry analysts or to a level that meets the expectations of
investors. The rate at which subscribers have increased in the past does not
necessarily indicate the rate at which subscribers may be expected to grow in
the future. In particular, while Excite@Home had forecasted that the number of
its subscribers could grow to up to 1.1 million by December 31, 1999 from more
than 620,000

                                       16
<PAGE>   25

subscribers at June 30, 1999, Excite@Home may not achieve this level of
subscriber growth.

EXCITE@HOME'S SUBSCRIBER GROWTH DEPENDS ON THE ACTIONS OF ITS CABLE PARTNERS,
AND IS LIMITED BY PRICE AND INSTALLATION CONSTRAINTS

     Excite@Home believes subscriber growth has been constrained, and will
continue to be constrained, by the cost and time required to install the @Home
service for each residential consumer. In addition, Excite@Home's growth has
been constrained by the rate at which Excite@Home's cable partners have upgraded
their systems and most of Excite@Home's cable partners are not obligated to
upgrade their cable infrastructures or market the @Home service. Moreover, the
@Home service is currently priced at a premium to many other online services,
and large numbers of subscribers may not be willing to pay a premium for the
@Home service.

IF EXCITE@HOME CANNOT MAINTAIN THE SCALABILITY, SPEED AND SECURITY OF ITS
NETWORK, CUSTOMERS WILL NOT ACCEPT ITS SERVICES

     Due to the limited deployment of Excite@Home's services, the ability of its
network to connect and manage a substantial number of online subscribers at high
transmission speeds is unknown. Therefore, Excite@Home faces risks related to
its network's ability to be scaled up to its expected subscriber levels while
maintaining superior performance. Excite@Home's network may be unable to achieve
or maintain a high speed of data transmission, especially as its subscribers
increase. In recent periods, the performance of the Excite@Home network has
experienced some deterioration in some markets as a result of subscriber abuse
of the @Home service. While Excite@Home is seeking to eliminate this abuse by
enforcing our acceptable user policy and by limiting users' upstream bandwidth,
Excite@Home's failure to do so may result in slower network performance and
reduced customer demand for Excite@Home's services. In addition, while
Excite@Home has taken steps to prevent users from sharing files via the @Home
service and to protect against bulk unsolicited e-mail, public concerns about
security, privacy and reliability of the cable network, or actual problems with
the security, privacy or reliability of Excite@Home's network, may inhibit the
acceptance of Excite@Home's Internet services.

IF NEW TWO-WAY CABLE MODEMS ARE NOT DEPLOYED TIMELY AND SUCCESSFULLY,
EXCITE@HOME MAY NOT BE ABLE TO GROW ITS SUBSCRIBER BASE QUICKLY

     Each Excite@Home subscriber currently must obtain a cable modem from a
cable partner to access the @Home service. The North American cable industry has
recently adopted interface standards known as DOCSIS for hardware and software
to support the delivery of data services over the cable infrastructure utilizing
compatible cable modems. Some of Excite@Home's cable partners have chosen to
delay some deployments of the @Home service until the widespread commercial
availability of DOCSIS-compliant cable modems. Subscriber growth could be
constrained and Excite@Home's business could be significantly harmed if its
cable partners choose to slow the deployment of the @Home service further. If
Excite@Home's cable partners are not able to obtain a sufficient quantity of
DOCSIS-compliant modems, Excite@Home's growth will be limited.

                                       17
<PAGE>   26

EXCITE@HOME COULD LOSE SUBSCRIBERS, DISTRIBUTION RELATIONSHIPS AND REVENUES TO
ITS COMPETITORS

     The markets for consumer and business Internet services and online content
are extremely competitive, and Excite@Home expects that competition will
intensify in the future. Excite@Home's most direct competitors in these markets
include the following:

     - Providers of cable-based Internet services. Time Warner Inc. and Media
       One Group have deployed high-speed Internet access services over their
       local cable networks through their own cable-based Internet service, Road
       Runner. Excite@Home currently competes with Road Runner to establish
       distribution arrangements with cable system operators and Excite@Home may
       compete for subscribers in the future if and when Excite@Home's cable
       partners cease to be subject to their exclusivity obligations. In
       addition, Excite@Home competes with other providers of cable-based
       Internet services, such as ISP Channel, Inc. and High Speed Access
       Corporation.

     - Telecommunications providers. Excite@Home competes with national long-
       distance and local exchange carriers that offer high-speed, Internet
       access services such as asymmetric digital subscriber line. If the
       advanced services offered by these companies are deregulated, this would
       further enhance the ability of these companies to compete against
       Excite@Home's services;

     - Internet and online service providers. Excite@Home competes with Internet
       service providers that provide basic Internet access services and with
       online service providers such as America Online; and

     - Internet content aggregators. Excite@Home competes with content
       aggregators and Internet portals including America Online, Yahoo! Inc.
       and Lycos, Inc. that seek to capture audience flow by providing
       ease-of-use and offering content that appeals to a broad audience.

     Many of Excite@Home's competitors and potential competitors have
substantially greater financial, technical and marketing resources, larger
subscriber bases, longer operating histories, greater name recognition and more
established relationships with advertisers and content and application providers
than Excite@Home does. These competitors may be able to undertake more extensive
marketing campaigns, adopt more aggressive pricing policies and devote more
resources to developing Internet services or online content than Excite@Home.
Excite@Home may not be able to compete successfully against current or future
competitors, and competitive pressures could significantly harm Excite@Home's
subscriber base, Excite@Home's ability to renew and enter into new distribution
agreements and Excite@Home's revenues.

EXCITE@HOME'S DEPENDENCE ON ITS NETWORK EXPOSES IT TO A SIGNIFICANT RISK OF
SYSTEM FAILURE

     Excite@Home's operations are dependent upon its ability to support its
highly complex network infrastructure and avoid damage from fires, earthquakes,
floods, power losses, telecommunications failures and similar events. The
occurrence of a natural disaster or other unanticipated problem at Excite@Home's
network operations center or at a number of Excite@Home's regional data centers
could cause interruptions in Excite@Home's services. Additionally, failure of
Excite@Home's cable partners or companies from which Excite@Home obtains data
transport services to provide the data

                                       18
<PAGE>   27

communications capacity that Excite@Home requires, for example as a result of
natural disaster, or operational disruption, could cause interruptions in the
services Excite@Home provide. Any damage or failure that causes interruptions in
Excite@Home's operations could harm Excite@Home's business.

YEAR 2000 ISSUES COULD AFFECT THE PERFORMANCE OF EXCITE@HOME'S SYSTEMS

     If Excite@Home's internal and network information systems do not correctly
recognize and process date information beyond the year 1999, Excite@Home may not
be able to conduct operations. Excite@Home may also experience supplier-related
Year 2000 problems. To address these Year 2000 issues, Excite@Home has initiated
a comprehensive program to address Year 2000 readiness in Excite@Home's systems
and its customers' and suppliers' systems. Delays in the implementation of new
information systems or a failure to fully identify all Year 2000 dependencies in
Excite@Home's existing systems and in the systems of Excite@Home's suppliers
could harm Excite@Home's business. Therefore, Excite@Home is developing, but
does not yet have, contingency plans for continuing operations in the event
these problems arise.

EXCITE@HOME'S LIMITED EXPERIENCE WITH INTERNATIONAL EXPANSION MAY PREVENT IT
FROM GROWING ITS BUSINESS OUTSIDE THE UNITED STATES

     A key component of Excite@Home's strategy is expansion into international
markets. Excite@Home has limited experience in developing localized versions of
its products and services and in developing relationships with international
cable system operators. Excite@Home may not be successful in expanding its
product and service offerings into foreign markets. In addition to the
uncertainty regarding Excite@Home's ability to generate revenues from foreign
operations and expand Excite@Home's international presence, Excite@Home faces
specific risks related to providing Internet services in foreign jurisdictions,
including:

     - regulatory requirements, including the regulation of Internet access;

     - legal uncertainty regarding liability for information retrieved and
       replicated in foreign jurisdictions; and

     - potential inability to use European customer information due to new
       European governmental regulations.

EXCITE@HOME'S BUSINESS MAY BE IMPACTED BY CABLE UNBUNDLING PROPOSALS AND OTHER
GOVERNMENT REGULATION

     Currently, Excite@Home's services are not directly subject to regulations
of the Federal Communication Commission or any other federal, state or local
communications regulatory agency. However, changes in the regulatory environment
relating to the Internet, cable television or telecommunications markets which
could require regulatory compliance by Excite@Home or which could impact its
exclusivity arrangements, subscribers and revenues include:

     - Federal regulation. Regulatory changes that affect telecommunications
       costs, limit usage of subscriber-related information or increase
       competition from telecommunications companies could affect Excite@Home's
       pricing or ability to market its services successfully. For example,
       reregulation of cable television rates may affect

                                       19
<PAGE>   28

       the speed at which Excite@Home's cable partners upgrade their cable
       systems to carry Excite@Home's services;

     - Regulation by local franchise authorities. Many of Excite@Home's United
       States cable partners' local cable affiliates have elected to classify
       the provision of the @Home service as additional cable services under
       their local franchise agreements, and to pay franchise fees under those
       agreements. Local franchise authorities may attempt to subject cable
       systems to higher or different franchise fees, taxes or requirements in
       connection with their distribution of the @Home service. There are
       thousands of franchise authorities, and thus it would be difficult or
       impossible for Excite@Home or its cable partners to operate under a
       unified set of franchise requirements; and

     - The FCC or local agencies could require Excite@Home's cable partners to
       grant competitors access to their cable systems. America Online,
       MindSpring Enterprises, Inc., Consumers Union and other parties have
       requested Congress, the Federal Communications Commission and state and
       local authorities to require cable operators to provide Internet and
       online service providers with unbundled access to their cable systems. If
       Excite@Home or its cable partners are classified as common carriers, or
       if government authorities require third-party access to cable networks or
       unaffiliated Internet service providers, Excite@Home's competitors may be
       able to provide service over its cable partner systems. The rates that
       Excite@Home's cable partners charge for this third-party access, or for
       the @Home Services, could also be subject to rate regulation or tariffing
       requirements.

     - Local Governmental Proceedings. Portland and Multnomah County, Oregon and
       Broward County, Florida, have imposed third-party access requirements on
       AT&T and other cable companies operating in those communities. The
       imposition of these requirements has been challenged in Federal Courts.
       In June 1999, a U.S. District Court upheld the third-party access
       requirement imposed on AT&T by Portland and Multnomah County. This
       decision has been appealed to the U.S. Court of Appeals for the Ninth
       Circuit. Denver, Colorado, King County, Washington, San Francisco and Los
       Angeles, California have considered imposing similar requirements and
       other municipalities may consider imposing similar requirements in the
       future.

       EXCITE@HOME COULD FACE LIABILITY FOR DEFAMATORY OR INDECENT CONTENT

     Claims could be made against Internet and online service providers under
both United States and foreign law for defamation, negligence, copyright or
trademark infringement, or other theories based on the nature and content of the
materials disseminated through their networks. Several private lawsuits seeking
to impose this liability are currently pending against Internet and online
services providers. In addition, legislation has been proposed that imposes
liability for or prohibits the transmission over the Internet of indecent
content. The imposition upon Internet and online service providers of potential
liability for information carried on or disseminated through their systems could
require Excite@Home to implement measures to reduce its exposure to this
liability. This may require that Excite@Home expend substantial resources or
discontinue service or product offerings. The increased focus on liability
issues as a result of these lawsuits and legislative proposals could impact the
growth of Internet use. Furthermore, some foreign governments, such as Germany,
have enacted laws and regulations governing content distributed over the
Internet that are more strict than those currently in place in the United
States. One or more of these factors could significantly harm Excite@Home's
business.

                                       20
<PAGE>   29

RISKS RELATED TO EXCITE@HOME'S RELATIONSHIPS WITH ITS CABLE PARTNERS

     The success of Excite@Home's business depends on Excite@Home's
relationships with its cable partners, most of which have agreed to provide
Excite@Home's high-speed residential Internet access services on an exclusive
basis. In return, Excite@Home has agreed not to provide a variety of Internet
services in the areas covered by its cable partners. Excite@Home's agreements
with its cable partners are complex. Some of the risks associated with these
relationships are set forth below. For a summary of some of the key aspects of
these agreements, you should refer to Excite@Home's annual report on Form 10-K/A
for the year ended December 31, 1998.

EXCITE@HOME DEPENDS ON ITS CABLE PARTNERS TO UPGRADE TO THE TWO-WAY CABLE
INFRASTRUCTURE NECESSARY TO SUPPORT THE @HOME SERVICE; THE AVAILABILITY AND
TIMING OF THESE UPGRADES ARE UNCERTAIN

     Transmission of the @Home service and cable-based @Work services depends on
the availability of high-speed two-way hybrid fiber coaxial cable
infrastructure. However, only a portion of existing cable plant in the United
States and in some international markets has been upgraded to two-way hybrid
fiber coaxial cable, and even less is capable of high-speed two-way
transmission. As of June 30, 1999, approximately 29% of Excite@Home's North
American cable partners' cable infrastructure was capable of delivering the
@Home service. Excite@Home's cable partners have announced and begun to
implement major infrastructure investments in order to deploy two-way hybrid
fiber coaxial cable. However, these investments have placed a significant strain
on the financial, managerial, operating and other resources of Excite@Home's
cable partners, most of which are already highly leveraged. Therefore, these
infrastructure investments have been, and Excite@Home expects will continue to
be, subject to change, delay or cancellation. Although Excite@Home's commercial
success depends on the successful and timely completion of these infrastructure
upgrades, most of Excite@Home's cable partners are under no obligation to
upgrade systems or to introduce, market or promote Excite@Home's services. The
failure of Excite@Home's cable partners to complete these upgrades in a timely
and satisfactory manner, or at all, would prevent Excite@Home from delivering
high-performance Internet services and would significantly harm Excite@Home's
business.

EXCITE@HOME'S CABLE PARTNERS ARE NOT GENERALLY OBLIGATED TO CARRY EXCITE@HOME'S
SERVICES, AND THE EXCLUSIVITY OBLIGATIONS THAT PREVENT THEM FROM CARRYING
COMPETING SERVICES MAY BE TERMINATED

     Excite@Home's cable partners are subject to exclusivity obligations that
prohibit them from obtaining high-speed, greater than 128 kilobits per second,
residential consumer Internet services from any source other than Excite@Home.
However, most of Excite@Home's cable partners are under no affirmative
obligation to carry any of Excite@Home's services. Also, the exclusivity
obligations of Excite@Home's principal cable partners, TCI, Comcast Corporation,
Cox Communications, Inc. and Cablevision Systems Corp., expire on June 4, 2002,
and may be terminated sooner under some circumstances, including:

     - Excite@Home's principal cable partners may terminate all their
       exclusivity obligations upon a change in law that materially impairs some
       of their rights;

     - Comcast or Cox may terminate all exclusivity obligations of Excite@Home's
       principal cable partners at any time if there is a change of control of
       TCI that

                                       21
<PAGE>   30

results within 12 months in the incumbent TCI directors no longer constituting a
majority of TCI's board. AT&T, TCI, Comcast and Cox have agreed, however, that
AT&T's acquisition of TCI did not constitute a change of control under the terms
      of the original agreement;

     - Cox or Comcast may terminate the exclusivity provisions of Excite@Home's
       principal cable partners if AT&T and its affiliates did not meet
       specified subscriber penetration levels for the @Home service. On June 4,
       1999, Cox had this right, but Cox has agreed to waive it for 1999; and

     - Comcast may terminate its own exclusivity obligations after June 4, 1999
       if it allows Excite@Home to repurchase a portion of Comcast's equity
       interest in Excite@Home. Comcast has informed Excite@Home that it has
       entered into an agreement with Microsoft Corporation under which
       Microsoft can require Comcast to terminate its exclusivity obligations.

     In consideration for Cox's agreement to waive its right to terminate
exclusivity as of June 4, 1999, Excite@Home's board approved changes to
Excite@Home's corporate governance on April 16, 1999. Excite@Home's stockholders
approved these changes on May 28, 1999. These governance changes generally
require board action to be approved by a majority of Excite@Home's board,
including the board representatives of AT&T and either Cox or Comcast. In
addition, as further consideration for Cox's waiver, AT&T agreed to increase its
subscriber acquisition goals for the next twelve months above its current goal
for that period.

     If the exclusivity obligations of Excite@Home's cable partners are
terminated, this could significantly harm Excite@Home's business and cause an
immediate drop in Excite@Home's stock price.

EXCITE@HOME IS CONTROLLED BY TCI AND AT&T

     TCI controls approximately 57% of Excite@Home's voting power. AT&T owns TCI
and therefore controls Excite@Home. Currently, four of Excite@Home's eleven
directors are directors, officers or employees of TCI, AT&T or their affiliates.
TCI currently owns all 30,800,000 outstanding shares of Excite@Home's Series B
common stock, each of which carries ten votes per share. This Series B common
stock ownership gives TCI the right to elect five Series B directors, one of
which is designated by Comcast and one of which is designated by Cox. So long as
TCI owns at least 15,400,000 shares of Excite@Home's Series B common stock and
holds a majority of Excite@Home's voting power, Excite@Home's board may take
action only if approved by the board and by at least 75%, or four of the five,
of Excite@Home's Series B directors. As a result, corporate actions generally
require the approval of TCI's three Series B directors and one, or in some cases
both, of the directors designated by Comcast and Cox. Therefore, Comcast and
Cox, acting together, may veto any board action.

EXCITE@HOME DEPENDS ON TELEPORT COMMUNICATIONS GROUP FOR LOCAL
TELECOMMUNICATIONS SERVICES FOR THE @WORK SERVICES

     Excite@Home depends on Teleport Communications Group, which is owned by
AT&T, to provide local telecommunications services and co-location within TCG's
facilities on favorable economic terms. This relationship enables Excite@Home to
provide @Work services to an entire metropolitan area in which TCG has
facilities. If

                                       22
<PAGE>   31

Excite@Home were required to obtain comparable telecommunications services from
local exchange carriers, Excite@Home would effectively be limited to providing
@Work services to commercial customers within a ten-mile radius of one of
Excite@Home's points of presence. As a result, Excite@Home would be required to
build multiple points of presence to service an entire metropolitan area, which
would substantially increase Excite@Home's capital costs to enter new markets
and which could make market entry uneconomical. If Excite@Home were required to
pay standard local exchange carrier rates, the ongoing operating costs for @Work
services would be substantially higher. The loss of Excite@Home's strategic
relationship with TCG would significantly harm Excite@Home's ability to deploy
@Work services. In addition, TCG has acquired a provider of Internet-related
services to businesses and corporate customers and will compete directly with
the @Work Internet service. To the extent TCG acquires or enters into strategic
relationships with other Internet service providers, TCG may reduce its support
of the @Work services. Although there are alternative suppliers for TCG's
services, it could take a significant period of time for Excite@Home to
establish similar relationships, and equivalent terms might not be available.

EXCITE@HOME MAY FACE ADDITIONAL COMPETITION FROM AT&T

     AT&T operates businesses that could compete with Excite@Home's services,
notwithstanding any exclusivity obligations that may apply to it due to its
ownership of TCI. First, AT&T operates a consumer Internet service known as AT&T
WorldNet. Although AT&T WorldNet is currently a telephone dial-up service that
does not utilize broadband technologies, AT&T may be able to use non-cable-based
data transport mechanisms to offer high-speed residential Internet services that
compete with the @Home service. Second, AT&T owns TCG, which operates an
Internet service for business customers that competes with the @Work service.
The @Work business depends to a significant extent on Excite@Home's agreement
with TCG for local access telecommunications services. If TCG ceases to
cooperate with Excite@Home, the @Work business would be harmed. Because
Excite@Home's @Work business is not subject to the cable partners' exclusivity
obligations, AT&T or TCG are not limited in their ability to compete with the
@Work business. In addition, AT&T and Time Warner recently announced the
formation of a significant strategic relationship that will include a joint
venture to offer AT&T-branded cable telephony service to residential and small
business customers over Time Warner's existing cable television systems in 33
states. The relationship between AT&T and Time Warner could ultimately extend to
other broadband services, including cable Internet services, that compete with
the @Home service. AT&T may take actions that benefit TCG, WorldNet or other
services of AT&T or other parties to Excite@Home's detriment.

WARRANTS ISSUED TO EXCITE@HOME'S CABLE PARTNERS MAY RESULT IN ADDITIONAL
DILUTION TO EXCITE@HOME'S STOCKHOLDERS

     Excite@Home has entered into agreements with Cablevision, Rogers
Cablesystems Limited, Shaw Cablesystems Ltd. and other cable partners under
which Excite@Home issued warrants to purchase shares of Excite@Home Series A
common stock. Under these agreements, warrants to purchase 20,955,563 shares of
Excite@Home Series A common stock at an average price of $1.09 per share were
exercisable as of June 30, 1999. To the extent that Cablevision, Rogers, Shaw or
other cable partners become eligible to and exercise their warrants,
Excite@Home's stockholders would experience substantial dilution.

                                       23

Excite@Home also may issue additional stock, or warrants to purchase stock, at
prices less than fair market value in connection with efforts to expand
distribution of the @Home service.

RISKS ASSOCIATED WITH THE ACQUISITION OF EXCITE, INC. AND EXCITE'S BUSINESS BY
@HOME

EXCITE@HOME FACES SEVERAL TRANSITORY RISKS ASSOCIATED WITH THE ACQUISITION OF
EXCITE

     In May 1999, Excite, Inc. was acquired by At Home Corporation, which we
refer to as @Home for the period before the merger. This acquisition presents
the following risks:

     - Excite@Home may encounter substantial difficulties, costs and delays
       associated with integrating the operations of an acquired company. This
       process may disrupt Excite@Home's business if not completed in a timely
       and efficient manner;

     - The present and potential relationships of @Home and Excite with
       sponsors, content providers, advertisers, users and subscribers may be
       harmed by the merger of @Home and Excite; and

     - The merger of @Home and Excite may result in conflicts associated with
       exclusive rights that both @Home and Excite have granted to third parties
       with regard to content, relationships, sponsorships or other strategic
       relationships, and failure to resolve these conflicts could harm
       Excite@Home's business.

THE EXCITE SERVICE COULD LOSE USERS, ADVERTISERS AND REVENUES TO ITS COMPETITORS

     The Excite service competes with a number of companies both for users and
advertisers, and therefore for revenues. Excite@Home expects this competition
will intensify, particularly because there are few barriers to entry in this
market. Excite's competitors include:

     - Web portal companies such as Infoseek's Go Network, Lycos, Netscape's
       Netcenter and Yahoo!;

     - online service providers such as America Online and Microsoft's MSN
       service;

     - large media companies such as CBS, NBC, Time Warner and USA Networks,
       Inc., who have announced initiatives to develop Web services or partner
       with Web companies; and

     - providers of Web-based advertising solutions, including AdForce,
       advertising management software, including NetGravity, Inc., advertising
       supported content and traditional advertising media.

EXCITE@HOME DEPENDS ON SEVERAL THIRD PARTY RELATIONSHIPS FOR USERS, ADVERTISERS
AND REVENUES

     Excite@Home depends on a number of third party relationships to provide
users and content for its Excite services, including agreements for links to
Excite services to be placed on high-traffic Web sites and agreements for third
parties to provide content, games and e-mail for Excite Web sites. If these
relationships terminate and Excite@Home is not able to replace them, it could
lose users or advertisers, and this could harm the revenues of the Excite
business.

                                       24
<PAGE>   33

PRIVACY CONCERNS REGARDING THE USAGE OF DEMOGRAPHIC INFORMATION COULD PREVENT
EXCITE@HOME FROM BENEFITING FROM SELLING TARGETED ADVERTISING

     Due to privacy concerns regarding the usage of demographic information in
online advertising, some commentators and governmental bodies have suggested
limitations on technology that Excite@Home uses to deliver targeted advertising
and compile demographic information about users. Any reduction or limitation in
the use of this technology could result in lower advertising rates.

POTENTIAL LITIGATION WITH RESPECT TO INTELLECTUAL PROPERTY RIGHTS COULD HARM THE
EXCITE BUSINESS

     Many parties, including competitors of the Excite service, are actively
developing search, indexing and related Internet technologies. Some of these
parties have taken steps to protect these technologies, and Excite@Home believes
that others will follow. Therefore, Excite@Home believes that disputes regarding
the ownership of these technologies are likely to arise in the future.
Excite@Home may not be able to defend any litigation successfully. Even if
successful, defending litigation may be costly and may divert management
resources.

EXCITE@HOME'S BUSINESS DEPENDS ON THE CONTINUED GROWTH IN INTERNET USE GENERALLY
AND PORTAL WEB SITES IN PARTICULAR

     Excite@Home's business may be adversely affected if usage of the Internet
or other online services does not continue to grow. This growth could be
hindered by a number of factors including: the adequacy of the Internet's
infrastructure to meet increased usage demands; privacy and security concerns;
and availability of cost-effective services. Any of these issues could cause the
Internet's performance or level of usage to decline.

     The success of Excite@Home's Internet portals is also dependent on Internet
users continuing to use "portal" web sites for their information needs. If
Internet users begin to become less dependent on portal sites, but rather go
directly to particular web sites, Excite@Home's traffic levels could decrease,
which could make Excite@Home's web sites less attractive to advertisers.

                           THE IMALL SPECIAL MEETING

DATE, TIME AND PLACE

     The special meeting of iMALL stockholders will be held on October 27, 1999,
at 10:00 a.m. local time, at the Miramar Sheraton Hotel, 101 Wilshire Boulevard,
Santa Monica, California. This prospectus/proxy statement is being furnished in
connection with the solicitation by iMALL's board of proxies to be used at the
special meeting and at any and all adjournments and postponements of the special
meeting.

PURPOSE

     The purpose of the special meeting is to approve an amendment to the
articles of incorporation, as more fully described in this prospectus/proxy
statement, and to approve the merger agreement and the merger under which Shop
Nevada, a wholly-owned subsidiary of Excite@Home, would be merged with iMALL,
with iMALL continuing as the surviving corporation. iMALL stockholders may also
be asked to transact other business that may properly come before the special
meeting or any adjournment or postponement of the special meeting.

RECOMMENDATION OF IMALL'S BOARD OF DIRECTORS

     AFTER CAREFUL CONSIDERATION, IMALL'S BOARD HAS DETERMINED THE MERGER
AGREEMENT AND THE MERGER TO BE FAIR AND IN THE BEST INTERESTS OF THE IMALL
STOCKHOLDERS AND UNANIMOUSLY RECOMMENDS THAT IMALL STOCKHOLDERS VOTE "FOR"
APPROVAL OF THE AMENDMENT TO THE ARTICLES OF INCORPORATION, THE MERGER AGREEMENT
AND THE MERGER. THE UNANIMOUS RECOMMENDATION OF IMALL'S BOARD DID NOT INCLUDE
THE DIRECTOR DESIGNATED TO IMALL'S BOARD BY FIRST DATA, WHO APPROPRIATELY
ABSTAINED FROM VOTING ON THE AMENDMENT TO THE ARTICLES OF INCORPORATION, THE
MERGER AND THE MERGER AGREEMENT BECAUSE OF AN ACTUAL OR POTENTIAL CONFLICT OF
INTEREST.

RECORD DATE, OUTSTANDING SHARES AND VOTING RIGHTS

     iMALL's board has fixed September 20, 1999 as the record date for the
special meeting. Only holders of record of shares of iMALL common stock on the
record date are entitled to notice of and to vote at the special meeting. As of
the record date, there were 19,638,080 outstanding shares of iMALL common stock
held by approximately 676 holders of record. At the special meeting, each share
of iMALL common stock will be entitled to one vote. Accordingly, an aggregate of
19,638,080 votes may be cast at the special meeting by holders of iMALL common
stock.

VOTE REQUIRED; QUORUM

     The approval of the amendment to the articles of incorporation and the
approval of the merger agreement and the merger will require the affirmative
vote of the holders of a majority of the voting power of the shares of iMALL
common stock outstanding on the record date.

     The representation, in person or by properly executed proxy, of the holders
of a majority of the voting power of the shares of stock entitled to vote at the
special meeting is necessary to constitute a quorum at the special meeting.
Shares of iMALL common

                                       26
<PAGE>   35

stock represented in person or by proxy will be counted for the purposes of
determining whether a quorum is present at the special meeting. Shares that
abstain from voting on the proposals will be treated as shares that are present
and entitled to vote at the special meeting for purposes of determining whether
a quorum exists, but abstentions will have the same effect as votes against the
proposals. Broker non-votes will be treated as present and entitled to vote at
the special meeting for purposes of determining whether a quorum exists. Brokers
or nominees holding shares of record for customers will not be entitled to vote
on the proposals unless they receive voting instructions from their customers.
Accordingly, broker non-votes will not be voted in favor of the proposals
meaning that such shares will have the same effect as shares voted against
proposals.

     As of the record date, iMALL's directors and executive officers and their
affiliates beneficially owned approximately 20.9% of the votes represented by
the outstanding shares of iMALL common stock. Stockholders of iMALL who, as of
the record date, control 41.9% of the votes entitled to be cast at the special
meeting, have agreed to vote all of their shares in favor of the proposal to
approve the amendment to the articles of incorporation and the proposal to
approve the merger agreement and the merger at the special meeting under voting
agreements entered into with Excite@Home. See "Related Agreements -- Voting
agreements."

VOTING OF PROXIES

     All shares of iMALL common stock that are entitled to vote and are
represented at the special meeting by properly executed proxies received prior
to or at the special meeting, and not revoked, will be voted at such meeting in
accordance with the instructions indicated on such proxies. If no instructions
are indicated, those proxies will be voted against the proposals. iMALL's board
does not know of any matters other than those described in the notice of the
special meeting that are to come before such meeting. If any other matters are
properly presented at the special meeting for consideration, including, among
other things, consideration of a motion to adjourn or postpone such meeting to
another time and/or place for the purposes of soliciting additional proxies or
allowing additional time for the satisfaction of conditions to the merger, the
persons named in the enclosed form of proxy and acting under the proxy generally
will have discretion to vote on those matters in accordance with their best
judgment.

REVOCATION OF PROXIES

     Any proxy given pursuant to this solicitation may be revoked by the person
giving it at any time before it is voted. Proxies may be revoked by:

     - filing with the Secretary of iMALL, at or before the taking of the vote
       at the special meeting, a written notice of revocation bearing a later
       date than the proxy; or

     - duly executing a later-dated proxy relating to the same shares and
       delivering it to the Secretary of iMALL before the taking of the vote at
       the special meeting.

     Any written notice of revocation or subsequent proxy should be sent to
iMALL, Inc., 233 Wilshire Boulevard, Suite 820, Santa Monica, California 90401,
Attention: Secretary, or hand delivered to the Secretary of iMALL at or before
the taking of the vote at the special meeting. Stockholders that have instructed
a broker to vote their shares must follow

                                       27
<PAGE>   36

directions received from such broker in order to change their vote or to vote at
the special meeting.

SOLICITATION OF PROXIES; EXPENSES

     All expenses of iMALL's solicitation of proxies will be borne by iMALL. The
cost of preparing and mailing this prospectus/proxy statement to iMALL
stockholders, will be shared equally by iMALL and Excite@Home. In addition to
solicitation by use of the mails, proxies may be solicited from iMALL
stockholders by directors, officers and employees of iMALL in person or by
telephone, facsimile or other means of communication. Such directors, officers
and employees will not be additionally compensated, but may be reimbursed for
reasonable out-of-pocket expenses in connection with such solicitation. iMALL
has retained MacKenzie Partners, Inc., a proxy solicitation firm, for assistance
in connection with the solicitation of proxies for the iMALL special meeting at
an estimated cost of $3,500 plus expenses. Arrangements will also be made with
brokerage houses, custodians, nominees and fiduciaries for forwarding of proxy
solicitation materials to beneficial owners of shares held of record by such
brokerage houses, custodians, nominees and fiduciaries, and iMALL will reimburse
such brokerage houses, custodians, nominees and fiduciaries for their reasonable
expenses incurred in forwarding such materials.

APPRAISAL RIGHTS

     Under the Nevada Revised Statutes, the holders of iMALL common stock are
not entitled to any appraisal or dissenters' rights with respect to the merger
because shares of iMALL common stock are included in the National Market System
of the National Association of Securities Dealers, Inc.

BACKGROUND OF THE MERGER

     During the first quarter of 1999, Richard Rosenblatt, Chairman of the Board
and Chief Executive Officer of iMALL, together with other members of the senior
management of iMALL, conducted a strategic review of iMALL's plans to achieve
increased scale in its business. The review included scenarios in which iMALL
would pursue an independent growth strategy as well as options to pursue a
business combination and/or strategic partnership with a range of companies.

     During February, March and April of 1999, Mr. Rosenblatt and other iMALL
executives held numerous discussions and telephonic meetings with executives of
Excite@Home to discuss a possible commercial transaction between Excite@Home and
iMALL under which Excite@Home would resell iMALL's products and services on a
non-exclusive basis. These telephone calls led to additional telephonic
discussions in April 1999 in which Mr. Rosenblatt and Don Hutchison, Senior Vice
President and General Manager of the @Work division of Excite@Home, and other
executives of Excite@Home discussed the merits of a possible strategic business
combination of the companies.

     During an informational conference call with iMALL's board on April 6,
1999, Mr. Rosenblatt discussed with the board the trend toward consolidation in
the Internet industry and general market conditions, and reported to the board
on the relative benefits and detriments of the strategic alternatives that
senior management had been analyzing.

     On April 13, 1999, Mr. Rosenblatt, Anthony Mazzarella, the Executive Vice
President, Chief Financial Officer and Secretary of iMALL, and Joseph
Ruszkiewicz, the Executive Vice President and Chief Operating Officer of iMALL
met with Deana Bergquist, the @Work Product Line Manager and Eric Van
Miltenberg, the @Work Director of Business Development, in Santa Monica,
California to discuss strategic combination issues. Prior to the meeting,
Excite@Home and iMALL entered into a confidentiality agreement providing for the
exchange of confidential information.

     On April 14, 1999, iMALL's executives held an informational conference call
with iMALL's board to discuss the status of discussions with Excite@Home and
other pending business. Mr. Rosenblatt reported to the board his discussions
with representatives of Excite@Home.

     During April and May of 1999, Mr. Rosenblatt had numerous telephone
conversations with John Duncan, the Executive Vice President of Business
Development of First Data

                                       29
<PAGE>   38

and a director of iMALL, regarding the strategic benefits that could result from
a possible business combination of Excite@Home and iMALL, including the benefits
of promoting the iMALL and First Data joint e-commerce solution through the
Excite portal web site and the @Home and @Work services.

     From April 13 through May 25, 1999, Mr. Rosenblatt held several telephonic
meetings with Mr. Hutchison, Mr. Van Miltenberg and Ms. Bergquist concerning a
possible business combination of the two companies.

     On May 25, 1999, Mr. Rosenblatt and Ms. Bergquist met in the Palo Alto,
California area to continue discussing a possible strategic combination.
Discussions resumed between Mr. Rosenblatt, Ms. Bergquist and Mr. Van Miltenberg
during a conference call on June 4, 1999.

     iMALL entered into an engagement letter with BancBoston Robertson Stephens
on June 14, 1999 under which BancBoston Robertson Stephens agreed to act as
iMALL's exclusive financial advisor for a business combination. On June 23, 1999
representatives of Excite@Home, iMALL, BancBoston Robertson Stephens, First Data
and Morgan Stanley & Co. Incorporated, Excite@Home's financial advisor, met in
Redwood City, California to discuss a strategic combination of Excite@Home and
iMALL and a long-term marketing relationship with First Data.

     On June 25, 1999, iMALL's board held a special meeting, together with
senior management of iMALL and representatives of BancBoston Robertson Stephens,
to discuss the status of discussions with Excite@Home. Mr. Rosenblatt reported
to the board his discussions with representatives of Excite@Home. iMALL's board
discussed the merits of iMALL remaining independent versus pursuing a business
combination with another company. iMALL's board authorized the continuation of
discussions with Excite@Home.

     Representatives of Excite@Home, iMALL, First Data, Morgan Stanley and
BancBoston Robertson Stephens next met in Englewood, Colorado on June 30, 1999.
During this meeting, representatives of Excite@Home and First Data explored what
form the relationship between Excite@Home and First Data would take if
Excite@Home were to acquire iMALL.

     On July 6, 1999, iMALL's board held a special meeting, together with senior
management of iMALL, iMALL's outside legal advisors and BancBoston Robertson
Stephens, to discuss the status of discussions with Excite@Home. Mr. Rosenblatt
reported to the board regarding his discussions with representatives of
Excite@Home, and the board authorized the continuation of discussions with
Excite@Home. Also on July 6, 1999, iMALL's board authorized iMALL's execution of
a non-solicitation agreement with Excite@Home, to expire on July 12, 1999,
during which period iMALL would not be permitted to negotiate with, or provide
information to, any other party regarding a business combination transaction.
The non-solicitation agreement was entered into on July 7, 1999.

     On July 7, 1999, Excite@Home's outside legal counsel sent to iMALL's
outside legal counsel a draft merger agreement and ancillary agreements. From
July 7 through July 11, iMALL and its financial advisors conducted a due
diligence review of Excite@Home, and Excite@Home and its outside legal and
financial advisors conducted a due diligence review of iMALL.

     On July 10, 1999, for the purpose of ensuring that the prohibitions imposed
by Nevada's "Combinations with Interested Stockholders" statutes would not apply
to the

                                       30
<PAGE>   39

transactions with Excite@Home, iMALL's board authorized the officers and agents
of iMALL to continue to negotiate with Excite@Home with a view to reaching an
agreement relating to, and finalizing, a definitive merger agreement with
Excite@Home, and to enter into such agreement, subject to the approval and
adoption by the board of directors and stockholders of iMALL of the terms
thereof.

     From July 10 to July 12, 1999, iMALL, Excite@Home and their respective
outside legal and financial advisors negotiated the terms of the merger
agreement and other agreements relating to the merger. The principal issues
discussed during these negotiations were the exchange ratio, the termination
rights under the merger agreement, the conditions upon which any breakup fee
would be payable, the representations, warranties and covenants contained in the
merger agreement, and the effect of the merger on iMALL's existing warrants and
outstanding stock options. In addition, during this period, Excite@Home and
iMALL held a series of negotiations with First Data regarding amendments to the
First Data Marketing and Development Agreement and the First Data Investment
Agreement and the execution of a Marketing Agreement and a Capacity Reservation
Agreement to be entered into between First Data and Excite@Home. Also during
this period, Excite@Home and iMALL held discussions with certain iMALL
stockholders concerning the voting agreements, with certain holders of iMALL's
warrants concerning an amendment to such holders' warrants to be effective upon
the closing of the merger and with certain officers of iMALL regarding their
employment agreements.

     On July 11, 1999, iMALL's board held a special meeting at which iMALL's
outside legal counsel reviewed the principal terms of the merger agreement, the
voting agreements, the amendment to iMALL's articles of incorporation, the
amendment to some of iMALL's warrants and the amendments to iMALL's existing
agreements with First Data. Additionally, iMALL's outside legal counsel reviewed
the iMALL board's fiduciary duties in considering a strategic business
combination. BancBoston Robertson Stephens then made a presentation to the board
regarding the financial analyses it had performed in connection with its opinion
and stated orally that it was prepared to render, and subsequently did provide,
its written opinion as of July 11, 1999 that, as of that date, the exchange
ratio in the merger was fair from a financial point of view to iMALL's
stockholders other than Excite@Home or any of its affiliates. See the section
entitled "Opinion of iMALL's financial advisor" below. Following a discussion,
iMALL's board unanimously approved the final terms of the merger agreement, the
merger and related agreements and the amendment to the articles of incorporation
and determined to recommend to the stockholders of iMALL that the merger
agreement and the merger be approved.

     On the evening of July 12, 1999, the merger agreement, the voting
agreements, the amendment to some of iMALL's warrants, the employment agreements
and the agreements with First Data were finalized and executed. The terms of the
merger were announced in a joint press release that was issued before the
opening of the stock markets on July 13, 1999.

IMALL'S REASONS FOR THE MERGER

     iMALL's board has determined that the terms of the merger and the merger
agreement are fair to, and in the best interests of, iMALL and its stockholders.
Accordingly, iMALL's board has unanimously approved the amendment to the
articles of incorporation, the merger agreement and the merger and unanimously
recommends that

                                       31
<PAGE>   40

you vote for approval of the amendment to the articles of incorporation, the
merger agreement and the merger.

     In reaching its decision, iMALL's board identified several potential
benefits of the merger, including:

     - The exchange ratio in the merger represented a premium of approximately
       39% over the average closing price for iMALL common stock over the 30 day
       trading period ending on July 9, 1999, the last trading day prior to the
       iMALL board meeting;

     - iMALL's board assessed the benefits of being part of a combined company
       and the risks of continuing to be an independent company, in view of the
       increased consolidation and increased competitive trends in the
       electronic commerce industry. iMALL's board believed that the combined
       company might be able to realize synergies in its combined operations as
       well as be able to possibly leverage Excite@Home's existing cable
       partners. iMALL's board considered favorably that the former iMALL
       stockholders, as stockholders of Excite@Home, would share the benefits of
       these synergies;

     - iMALL's board reviewed the principal terms and conditions of the merger
       agreement, including the representations, warranties and covenants and
       the conditions to each party's obligation to complete the merger. iMALL's
       board considered favorably that the terms of the merger agreement are
       reasonable;

     - iMALL's board considered the potential benefits of the merger to iMALL's
       customers and employees and the interests of the community and of
       society;

     - iMALL's board considered favorably the opinion of BancBoston Robertson
       Stephens, dated July 11, 1999, including the related financial analyses,
       to the effect that, as of that date and based upon and subject to the
       factors and assumptions set forth in the opinion, the exchange ratio was
       fair from a financial point of view to the holders of iMALL common stock,
       other than Excite@Home or any of its affiliates;

     - iMALL's board considered the larger market capitalization of Excite@Home,
       and the higher corresponding trading liquidity for former iMALL
       shareholders. Based on the closing prices of Excite@Home common stock and
       iMALL common stock on July 9, 1999, the last trading day prior to the
       iMALL board meeting, Excite@Home had a market capitalization of $19.752
       billion, compared to iMALL's market capitalization of $358 million.
       Accordingly, by combining with Excite@Home, iMALL's stockholders will be
       afforded substantially increased trading liquidity for their investment;
       and

     - iMALL's board considered the ability of Excite@Home and iMALL to complete
       the merger, including their ability to obtain necessary regulatory
       approvals and their obligations to attempt to obtain those approvals and
       the likelihood that the merger would be completed.

     iMALL's board also considered a number of potentially negative factors in
its deliberations concerning the merger, including:

     - iMALL's board considered the risk that because the exchange ratio will
       not be adjusted for changes in the market price of either Excite@Home
       Series A common

                                       32
<PAGE>   41

       stock or iMALL common stock, the per share value of the consideration to
       be received by iMALL stockholders might be less than the price per share
       implied by the exchange ratio immediately prior to the announcement of
       the merger;

     - iMALL's board considered the risk that the synergies and benefits sought
       in the merger would not be fully achieved, which might have the effect of
       adversely affecting the market value of the Excite@Home common stock
       received in the merger;

     - iMALL's board considered the risk that the merger would not be completed.
       In evaluating this risk, iMALL's board considered the circumstances under
       which Excite@Home could terminate the merger agreement;

     - iMALL's board considered the interests of its officers and directors in
       the merger; and

     - iMALL's board considered the risk that the negative features of the
       termination fee may prevent others from proposing an alternative
       transaction that may be more advantageous to iMALL stockholders. In
       determining the fairness of the merger to the stockholders of iMALL,
       iMALL's board took into account the size of the termination fee in
       relation to the size of the transaction and the circumstances in which it
       would be paid.

     The foregoing discussions of the information and factors considered by
iMALL's board are not intended to be exhaustive but are believed to include all
material factors considered by iMALL's board.

RECOMMENDATION OF IMALL'S BOARD OF DIRECTORS

     AFTER CAREFUL CONSIDERATION, IMALL'S BOARD HAS DETERMINED THE MERGER
AGREEMENT AND THE MERGER TO BE FAIR TO AND IN THE BEST INTERESTS OF THE IMALL
STOCKHOLDERS AND UNANIMOUSLY RECOMMENDS THAT IMALL STOCKHOLDERS VOTE "FOR"
APPROVAL OF THE AMENDMENT TO THE ARTICLES OF INCORPORATION, THE MERGER AGREEMENT
AND THE MERGER. THE UNANIMOUS RECOMMENDATION OF IMALL'S BOARD DID NOT INCLUDE
THE DIRECTOR DESIGNATED TO IMALL'S BOARD BY FIRST DATA, WHO APPROPRIATELY
ABSTAINED FROM VOTING ON THE AMENDMENT TO THE ARTICLES OF INCORPORATION, THE
MERGER AND THE MERGER AGREEMENT BECAUSE OF AN ACTUAL OR POTENTIAL CONFLICT OF
INTEREST.

OPINION OF IMALL'S FINANCIAL ADVISOR

     Under an engagement letter dated June 14, 1999, and amended on June 18,
1999, iMALL engaged BancBoston Robertson Stephens to render an opinion as to the
fairness of the exchange ratio, from a financial point of view, to holders of
shares of iMALL common stock, other than Excite@Home or any of its affiliates.

     On July 11, 1999 at a meeting of iMALL's board held to evaluate the
proposed merger, BancBoston Robertson Stephens delivered to iMALL's board its
written opinion that, as of July 11, 1999 and based on the assumptions made, the
matters considered and the limitations on the review undertaken described in the
opinion, the exchange ratio was fair, from a financial point of view, to the
holders of shares of iMALL common stock, other than Excite@Home or any of its
affiliates. The exchange ratio was determined through negotiations between the
respective managements of iMALL and Excite@Home. Although BancBoston Robertson
Stephens did assist the management of iMALL in these

                                       33
<PAGE>   42

negotiations, it was not asked to, and did not, recommend to iMALL that any
specific exchange ratio constituted the appropriate exchange ratio for the
merger. BancBoston Robertson Stephens assisted iMALL's management in the
negotiations leading to an agreement on principal structural terms of the
merger.

     The full text of the BancBoston Robertson Stephens opinion, which sets
forth, among other things, assumptions made, matters considered and limitations
on the review undertaken, is attached as Annex C and is incorporated in this
prospectus/proxy statement by reference. iMALL urges its stockholders to read
the BancBoston Robertson Stephens opinion in its entirety. The BancBoston
Robertson Stephens opinion was prepared for the benefit and use of iMALL's board
in connection with its evaluation of the merger and does not constitute a
recommendation to stockholders of iMALL as to how they should vote, or take any
other action, with respect to the merger.

     The BancBoston Robertson Stephens opinion does not address:

     - the relative merits of the merger and the other business strategies that
       iMALL's board has considered or may be considering; or

     - the underlying business decision of iMALL's board to proceed with the
       merger.

     The summary of the BancBoston Robertson Stephens opinion set forth in this
prospectus/proxy statement is qualified in its entirety by reference to the full
text of the BancBoston Robertson Stephens opinion.

     In connection with the preparation of the BancBoston Robertson Stephens
opinion, BancBoston Robertson Stephens, among other things:

     - reviewed certain publicly available financial statements and other
       business and financial information of iMALL and Excite@Home,
       respectively;

     - reviewed certain internal financial statements and other financial and
       operating data concerning iMALL prepared by the management of iMALL;

     - reviewed certain financial forecasts and other forward looking financial
       information prepared by the management of iMALL;

     - reviewed with Excite@Home certain publicly available estimates of
       research analysts relating to Excite@Home;

     - held discussions with the respective managements of Excite@Home and iMALL
       concerning the businesses, past and current operations, financial
       condition and future prospects of both iMALL and Excite@Home,
       independently and combined, including discussions with the managements of
       iMALL and Excite@Home concerning cost savings and other synergies that
       are expected to result from the merger, as well as their views regarding
       the strategic rationale for the merger;

     - reviewed the financial terms and conditions set forth in the merger
       agreement and the agreements ancillary thereto;

     - reviewed the stock price and trading history of iMALL and Excite@Home;

     - compared the financial performance of iMALL and Excite@Home and the
       prices and trading activity of iMALL common stock and Excite@Home Series
       A

                                       34
<PAGE>   43

       common stock with that of certain other publicly traded companies it
       deemed comparable with iMALL and Excite@Home, respectively;

     - compared the financial terms of the merger with the financial terms, to
       the extent publicly available, of other transactions that it deemed
       relevant;

     - reviewed the pro forma impact of the merger on Excite@Home's cash
       earnings per share and revenue per share;

     - participated in discussions and negotiations among representatives of
       iMALL and Excite@Home and their financial and legal advisors; and

     - made such other studies and inquiries, and reviewed such other data, as
       it deemed relevant.

     In its review and analysis, and in arriving at its opinion, BancBoston
Robertson Stephens assumed and relied upon the accuracy and completeness of all
of the financial and other information provided to it (including information
furnished to it orally or otherwise discussed with it by the managements of
iMALL and Excite@Home) or publicly available and neither attempted to verify,
nor assumed responsibility for verifying, any of such information. BancBoston
Robertson Stephens relied upon the assurances of managements of iMALL and
Excite@Home that they were not aware of any facts that would make such
information inaccurate or misleading. Furthermore, BancBoston Robertson Stephens
did not obtain or make, or assume any responsibility for obtaining or making,
any independent evaluation or appraisal of the properties, assets or liabilities
(contingent or otherwise) of iMALL or Excite@Home, nor was BancBoston Robertson
Stephens furnished with any such evaluation or appraisal.

     With respect to the financial forecasts and projections (and the
assumptions and bases therefor) for each of iMALL and Excite@Home that
BancBoston Robertson Stephens reviewed, upon the advice of the managements of
iMALL and Excite@Home, BancBoston Robertson Stephens assumed that such forecasts
and projections:

     - had been reasonably prepared in good faith on the basis of reasonable
       assumptions;

     - reflected the best available estimates and judgments as to the future
       financial condition and performance of iMALL and Excite@Home,
       respectively; and

     - will be realized in the amounts and in the time periods estimated.

     In this regard, BancBoston Robertson Stephens noted that each of iMALL and
Excite@Home face exposure to the Year 2000 problem. BancBoston Robertson
Stephens did not undertake any independent analysis to evaluate the reliability
or accuracy of the assumptions made by the managements of iMALL and Excite@Home
with respect to the potential effect that the Year 2000 problem might have on
their respective forecasts.

     In addition, BancBoston Robertson Stephens assumed that:

     - the merger will be consummated upon the terms set forth in the merger
       agreement without material alteration thereof, including, among other
       things, that the merger will be accounted for as a "purchase method"
       business combination in accordance with generally accepted accounting
       principles;

     - the merger will be treated as a tax-free reorganization pursuant to the
       Internal Revenue Code of 1986, as amended;

                                       35
<PAGE>   44

     - the agreements with First Data described in the merger agreement will be
       executed and in full force and effect; and

     - the historical financial statements of each of iMALL and Excite@Home
       reviewed by it had been prepared and fairly presented in accordance with
       generally accepted accounting principles consistently applied.

     BancBoston Robertson Stephens relied as to all legal matters relevant to
rendering its opinion on the advice of counsel.

     Although developments following the date of the BancBoston Robertson
Stephens opinion may affect the opinion, BancBoston Robertson Stephens assumed
no obligation to update, revise or reaffirm its opinion. The BancBoston
Robertson Stephens opinion is necessarily based upon market, economic and other
conditions as in effect on, and information made available to BancBoston
Robertson Stephens as of, the date of the BancBoston Robertson Stephens opinion.
It should be understood that subsequent developments may affect the conclusion
expressed in the BancBoston Robertson Stephens opinion and that BancBoston
Robertson Stephens disclaims any undertaking or obligation to advise any person
of any change in any matter affecting the opinion which may come or be brought
to its attention after the date of the opinion. The BancBoston Robertson
Stephens opinion is limited to the fairness, from a financial point of view and
as of the date thereof, of the exchange ratio to holders of shares of iMALL
common stock, other than Excite@Home or any of its affiliates. BancBoston
Robertson Stephens does not express any opinion as to:

     - the value of any employee agreement or other arrangement entered into in
       connection with the merger;

     - any tax or other consequences that might result from the merger; or

     - what the value of Excite@Home common stock will be when issued to iMALL's
       stockholders pursuant to the merger or the price at which the shares of
       Excite@Home common stock that are issued pursuant to the merger may be
       traded in the future.

     The following is a summary of the material financial analyses performed by
BancBoston Robertson Stephens in connection with rendering the BancBoston
Robertson Stephens opinion. The summary of the financial analyses is not a
complete description of all of the analyses performed by BancBoston Robertson
Stephens. Certain of the information in this section is presented in a tabular
form. IN ORDER TO BETTER UNDERSTAND THE FINANCIAL ANALYSES PERFORMED BY
BANCBOSTON ROBERTSON STEPHENS, THESE TABLES MUST BE READ TOGETHER WITH THE TEXT
OF EACH SUMMARY. THE BANCBOSTON ROBERTSON STEPHENS OPINION IS BASED UPON THE
TOTALITY OF THE VARIOUS ANALYSES PERFORMED BY BANCBOSTON ROBERTSON STEPHENS AND
NO PARTICULAR PORTION OF THE ANALYSES HAS ANY MERIT STANDING ALONE. BancBoston
Robertson Stephens noted that based on the closing price of Excite@Home common
stock on July 9, 1999 of $53.81, the exchange ratio in the merger of 0.460x
implied an iMALL equity value of approximately $588 million and an iMALL equity
value per share of $24.75.

     PRECEDENT TRANSACTION ANALYSIS. Using publicly available information,
BancBoston Robertson Stephens analyzed the consideration offered, the premiums
paid and the implied transaction value multiples paid or proposed to be paid in
selected acquisition transactions in the Internet content and service industry,
including:

     - AboveNet Communications Inc./Metromedia Fiber Network, Inc. (June 24,
       1999)

     - TeleBank Financial Corporation/E*TRADE Group, Inc. (June 1, 1999)

     In analyzing these "precedent transactions", BancBoston Robertson Stephens
compared, among other things, the total consideration in such transactions as a
multiple of the next twelve months ("NTM") estimated revenues and estimated
fiscal year 2000 revenues. All multiples for the precedent transactions were
based on public information available at the time of the announcement. Based on
this information and other publicly available information, the following table
illustrates the implied iMALL equity valuations, iMALL equity valuations per
share and exchange ratios derived from applying a range of multiples that
BancBoston Robertson Stephens derived from the precedent transactions:

     BancBoston Robertson Stephens also considered the premiums paid in the
precedent transactions over the target's closing share price the day before the
transaction was announced, the target's closing share price one month prior to
the announcement, the average closing share price 10 days prior to the
announcement, the average closing share price 20 days prior to the announcement
and the average closing share price 30 days prior to the announcement. Based on

     No company, business or transaction compared in the comparable companies
analysis or precedent transaction analysis is identical to iMALL or Excite@Home.
Accordingly, an analysis of the results of the foregoing is not entirely
mathematical; rather it involves complex considerations and judgments concerning
differences in financial and operating characteristics and other factors that
could affect the acquisition, public trading and other values of the comparable
companies, precedent transactions or the business segment, company or
transactions to which they are being compared.

     PRO FORMA ANALYSIS. BancBoston Robertson Stephens analyzed certain pro
forma effects resulting from the merger, including, among other things, the
impact of the merger on the projected cash earnings per share and revenues per
share of the combined company for fiscal years 1999 and 2000. The following
table summarizes the results of such analysis:

<TABLE>
<S>                                                           <C>

The actual results achieved by the combined company may vary from projected
results and the variations may be material.

     OTHER FACTORS AND COMPARATIVE ANALYSES. In rendering its opinion,
BancBoston Robertson Stephens considered certain other factors and conducted
certain other comparative analyses, including, among other things a review of:

     - the history of trading prices and volume for iMALL common stock and
       Excite@Home common stock for the period from July 9, 1998 to July 9,
       1999; and

     - selected published analysts' reports on iMALL and Excite@Home, including
       analysts' estimates as to the earnings growth potential of iMALL and
       Excite@Home.

     While the foregoing summary describes certain analyses and factors that
BancBoston Robertson Stephens deemed material in its presentation to iMALL's
board, it is not a comprehensive description of all analyses and factors
considered by BancBoston Robertson Stephens. The preparation of a fairness
opinion is a complex process that involves various determinations as to the most
appropriate and relevant methods of financial analysis and the application of
these methods to the particular circumstances and, therefore, such an opinion is
not readily susceptible to summary description. BancBoston Robertson Stephens
believes that its analyses must be considered as a whole and that selecting
portions of its analyses and of the factors considered by it, without
considering all analyses and factors, would create an incomplete view of the
evaluation process underlying the BancBoston Robertson Stephens opinion. Several
analytical methodologies were employed and no one method of analysis should be
regarded as critical to the overall conclusion reached by BancBoston Robertson
Stephens. Each analytical technique has inherent strengths and weaknesses, and
the nature of the available information may further affect the value of
particular techniques. The conclusions reached by BancBoston Robertson Stephens
are based on all analyses and factors taken as a whole and also on application
of BancBoston Robertson Stephens' own experience and judgment. Such conclusions
may involve significant elements of subjective judgment and qualitative
analysis. BancBoston Robertson Stephens therefore gives no opinion as to the
value or merit standing alone of any one or more parts of the analysis it
performed. In performing its analyses, BancBoston Robertson Stephens considered
general economic, market and financial conditions and other matters, many of
which are beyond the control of iMALL and Excite@Home. The analyses performed by
BancBoston Robertson Stephens are not necessarily indicative of actual values or
future results, which may be significantly more or less favorable than those
suggested by such analyses. Accordingly, analyses relating to the value of a
business do not purport to be appraisals or to reflect the prices at which the
business actually may be purchased. Furthermore, no opinion is being expressed
as to the prices at which shares of iMALL common stock or Excite@Home common
stock may be traded at any future time.

     The engagement letter between BancBoston Robertson Stephens and iMALL
provides that, for its services, BancBoston Robertson Stephens is entitled to
receive a transaction fee equal to $1.0 million plus two percent (2%) of the
aggregate transaction value, if any, exceeding a purchase price of $20.00 per
share of iMALL common stock. iMALL has also agreed to reimburse BancBoston
Robertson Stephens for certain of its out-of-pocket expenses, including legal
fees, and to indemnify and hold harmless BancBoston Robertson Stephens and its
affiliates and any director, employee or agent of BancBoston Robertson Stephens
or any of its affiliates, or any person controlling BancBoston Robertson
Stephens or its affiliates for certain losses, claims, damages, expenses and
liabilities relating to or

                                       40
<PAGE>   49

arising out of services provided by BancBoston Robertson Stephens as financial
advisor to iMALL. The terms of the fee arrangement with BancBoston Robertson
Stephens, which iMALL and BancBoston Robertson Stephens believe are customary in
transactions of this nature, were negotiated at arm's length between iMALL and
BancBoston Robertson Stephens, and iMALL's board was aware of such fee
arrangements, including the fact that a significant portion of the fees payable
to BancBoston Robertson Stephens is contingent upon completion of the merger. In
the past, BancBoston Robertson Stephens has provided certain investment banking
services to iMALL for which it has been paid fees. In the ordinary course of its
business, BancBoston Robertson Stephens may trade in iMALL's securities and
Excite@Home's securities for its own account and the account of its customers
and, accordingly, may at any time hold a long or short position in iMALL's
securities or Excite@Home's securities.

     BancBoston Robertson Stephens was retained based on BancBoston Robertson
Stephens' experience as a financial advisor in connection with mergers and
acquisitions and in securities valuations generally, as well as BancBoston
Robertson Stephens' investment banking relationship and familiarity with iMALL.

     BancBoston Robertson Stephens is an internationally recognized investment
banking firm. As part of its investment banking business, BancBoston Robertson
Stephens is frequently engaged in the valuation of businesses and their
securities in connection with mergers and acquisitions, negotiated
underwritings, secondary distributions of securities, private placements and
other purposes.

INTERESTS OF CERTAIN PERSONS IN THE MERGER

     In considering the recommendations of iMALL's board, you should be aware of
the interests that directors and officers of iMALL have in the merger. These
interests are different from and in addition to your interests as stockholders.
These include:

     - Richard Rosenblatt, Joseph Ruszkiewicz, Anthony Mazzarella, Stephen
       Fulling, Daniel Odette and Phillip Windley have entered into employment
       agreements and will be employed by Excite@Home or the company resulting
       from the merger after completion of the merger.

     - First Data, which as of the record date owned 10.2% of the outstanding
       shares of iMALL common stock, entered into a marketing agreement, an
       amended marketing and development agreement and a capacity reservation
       agreement and, upon completion of the merger, will enter into a
       registration rights agreement with Excite@Home. In addition, if the
       merger is completed, Excite@Home will issue First Data a warrant to
       purchase 2,300,000 shares of its Series A common stock at an exercise
       price of $36.96 per share.

     - iMALL's directors and officers have customary rights to indemnification
       against liabilities.

     As a result, these directors and officers could be more likely to vote to
approve the merger agreement and the merger than if they did not hold these
interests.

COMPLETION AND EFFECTIVENESS OF THE MERGER

     The merger will be completed when all of the conditions to completion of
the merger are satisfied or waived, including the approval of the amendment to
the articles of

                                       41
<PAGE>   50

incorporation, the merger agreement and the merger by the stockholders of iMALL.
The merger will become effective upon the filing of articles of merger in the
office of the Secretary of State of the State of Nevada.

STRUCTURE OF THE MERGER AND CONVERSION OF IMALL COMMON STOCK

     Shop Nevada, a newly-formed and wholly-owned subsidiary of Excite@Home,
will be merged with iMALL. As a result of the merger, the separate corporate
existence of Shop Nevada will cease and iMALL will survive the merger as a
wholly-owned subsidiary of Excite@Home.

     Upon completion of the merger, each outstanding share of iMALL common stock
will be converted into the right to receive 0.46 of a share of Excite@Home
Series A common stock.

     No certificate or scrip representing fractional shares of Excite@Home
Series A common stock will be issued in connection with the merger. Instead,
iMALL's stockholders will receive cash, without interest, in lieu of any
fractional shares of Excite@Home Series A common stock.

EXCHANGE OF IMALL STOCK CERTIFICATES FOR EXCITE@HOME STOCK CERTIFICATES

     When the merger is completed, Excite@Home's exchange agent will mail to
iMALL stockholders a letter of transmittal and instructions for use in
surrendering iMALL stock certificates in exchange for Excite@Home stock
certificates. When you deliver your iMALL stock certificates to the exchange
agent along with an executed letter of transmittal and any other required
documents, your iMALL stock certificates will be canceled and you will receive
Excite@Home stock certificates representing the number of whole shares of
Excite@Home Series A common stock to which you are entitled under the merger
agreement. iMALL stockholders will receive payment in cash, without interest, in
lieu of any fractional shares of Excite@Home Series A common stock which would
have been otherwise issuable to iMALL stockholders in the merger.

YOU SHOULD NOT SUBMIT YOUR IMALL STOCK CERTIFICATES FOR EXCHANGE UNLESS AND
UNTIL YOU RECEIVE THE TRANSMITTAL INSTRUCTIONS AND A LETTER OF TRANSMITTAL FROM
THE EXCHANGE AGENT.

     iMALL stockholders are not entitled to receive any dividends or other
distributions on Excite@Home Series A common stock until the merger is completed
and they have surrendered their iMALL stock certificates in exchange for
Excite@Home stock certificates.

     Subject to the effect of applicable laws, promptly following surrender of
iMALL stock certificates and the issuance of the corresponding Excite@Home
certificates, iMALL stockholders will be paid the amount of dividends or other
distributions, without interest, with a record date after the completion of the
merger which were previously paid with respect to their whole shares of
Excite@Home Series A common stock. At the appropriate payment date, iMALL
stockholders will also receive the amount of dividends or other distributions,
without interest, with a record date after the completion of the merger and a
payment date after they exchange their iMALL stock certificates for Excite@Home
stock certificates.

                                       42
<PAGE>   51

     Excite@Home will only issue iMALL stockholders an Excite@Home stock
certificate or a check in lieu of a fractional share in a name in which the
surrendered iMALL stock certificate is registered. If you wish to have your
certificate issued in another name you must present the exchange agent with all
documents required to show and effect the unrecorded transfer of ownership and
show that you paid any applicable stock transfer taxes.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

     The following general discussion summarizes certain material United States
federal income tax consequences of the merger. This discussion is based on the
Internal Revenue Code, the related regulations promulgated, existing
administrative interpretations and court decisions, all of which are subject to
change, possibly with retroactive effect. This discussion assumes that iMALL
stockholders hold their shares of iMALL common stock as capital assets within
the meaning of section 1221 of the Internal Revenue Code. This discussion does
not address all aspects of United States federal income taxation that may be
important to you in light of your particular circumstances or if you are subject
to special rules. These special rules include rules relating to:

     - stockholders who are not citizens or residents of the United States;

     - financial institutions;

     - tax-exempt organizations;

     - insurance companies;

     - dealers in securities;

     - stockholders who acquired their shares of iMALL common stock through the
       exercise of options or similar derivative securities or otherwise as
       compensation; and

     - stockholders who hold their shares of iMALL common stock as part of a
       hedge, appreciated financial position, straddle or conversion
       transaction.

     In addition, the discussion below does not consider the effect of any
applicable state, local or foreign tax laws.

     Our obligations to complete the merger are conditioned on (1) the delivery
of an opinion to Excite@Home from Fenwick & West LLP and (2) the delivery of an
opinion to iMALL from Latham & Watkins, in each case regarding material United
States federal income tax consequences of the merger. Alternatively, this
condition will be satisfied upon (a) the delivery of such a tax opinion to
Excite@Home and iMALL from Latham & Watkins or (b) the delivery of such a tax
opinion to Excite@Home and iMALL from Fenwick & West LLP.

     Excite@Home and iMALL believe, based on the advice of their respective
counsel, that the merger will have the United States federal income tax
consequences discussed below. The opinions of counsel referred to above (1) will
assume the absence of changes in existing facts and (2) will rely on
assumptions, representations and covenants including those contained in
certificates executed by officers of Excite@Home, iMALL and others. The opinions
referred to above neither bind the Internal Revenue Service, or the IRS, nor
preclude the IRS from adopting a position contrary to that expressed in the
opinions, and no assurance can be given that contrary positions will not be
successfully asserted by the

                                       43
<PAGE>   52

IRS or adopted by a court if the issues are litigated. Neither of Excite@Home
and iMALL intends to obtain a ruling from the IRS with respect to the tax
consequences of the merger.

     EACH HOLDER OF IMALL COMMON STOCK IS URGED TO CONSULT HIS, HER OR ITS TAX
ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES TO HIM, HER OR IT OF THE
TRANSACTIONS DESCRIBED HEREIN, INCLUDING THE APPLICABILITY AND EFFECT OF ANY
STATE, LOCAL OR FOREIGN TAX LAWS, AND OF CHANGES IN APPLICABLE TAX LAWS.

     Tax consequences to iMALL and iMALL stockholders. The merger will
constitute a "reorganization" within the meaning of section 368(a) of the
Internal Revenue Code. Accordingly, subject to the limitations and
qualifications referred to herein, the following tax consequences will result:

     - No gain or loss will be recognized by iMALL solely as a result of the
       merger;

     - No gain or loss will be recognized by the holders of iMALL common stock
       upon the receipt of Excite@Home Series A common stock solely in exchange
       for the iMALL common stock in the merger, except to the extent of cash
       received in lieu of fractional shares;

     - Cash payments received by holders of iMALL common stock in lieu of a
       fractional share of Excite@Home Series A common stock will be treated as
       capital gain (or loss) measured by the difference between the cash
       payment received and the portion of the tax basis in the shares of iMALL
       common stock surrendered that is allocable to the fractional share. Such
       gain (or loss) will be long-term capital gain or loss if the fractional
       share of iMALL common stock is considered to have been held for more than
       one year at the effective time of the merger;

     - The aggregate tax basis of the Excite@Home Series A common stock received
       by iMALL stockholders in the merger, including any fractional share of
       Excite@Home Series A common stock not actually surrendered in exchange
       therefor, will be the same as the aggregate tax basis of the iMALL common
       stock surrendered in exchange therefor; and

     - The holding period of the Excite@Home Series A common stock received by
       each iMALL common stockholder in the merger will include the holding
       period of the iMALL common stock surrendered in exchange therefor.

     A successful IRS challenge to the "reorganization" status of the merger
would result in an iMALL stockholder recognizing gain or loss with respect to
each share of iMALL common stock surrendered in the merger equal to the
difference between the iMALL stockholder's basis in the share and the fair
market value, as of the effective time of the merger, of the Excite@Home Series
A common stock received in exchange therefor. In that event, an iMALL
stockholder's aggregate tax basis in the Excite@Home Series A common stock so
received would equal its fair market value as of the effective time of the
merger, and the iMALL stockholder's holding period for the Excite@Home Series A
common stock would begin the day after the merger.

     Tax Consequences to Excite@Home and Excite@Home's common stockholders. No
gain or loss will be recognized by Excite@Home solely as a result of the merger.
There will be no United States federal income tax consequences as a result of
the consummation of the merger to Excite@Home common stockholders.

ACCOUNTING TREATMENT OF THE MERGER

     Excite@Home intends to account for the merger as a purchase for financial
reporting and accounting purposes, under generally accepted accounting
principles. After completion of the merger, the results of operations of iMALL
will be included in the consolidated financial statements of Excite@Home. The
purchase price, i.e., the aggregate merger consideration, will be allocated
based on the fair values of the assets acquired and the liabilities assumed. Any
excess of cost over fair value of the net tangible assets of iMALL acquired will
be recorded as goodwill and other intangible assets and will be amortized by
charges to operations under generally accepted accounting principles. These
allocations will be made based upon valuations and other studies that have not
yet been finalized.

REGULATORY FILINGS AND APPROVALS REQUIRED TO COMPLETE THE MERGER

     The merger is subject to the requirements of the Hart-Scott-Rodino
Antitrust Improvements Act, which prohibits the completion of certain
transactions until required information and materials are furnished to the
Antitrust Division of the Department of Justice and the Federal Trade
Commission, and the applicable waiting period has expired or been terminated by
the Antitrust Division of the Department of Justice and the Federal Trade
Commission. On August 16, 1999, Excite@Home and iMALL filed the required
information and materials with the Department of Justice and the Federal Trade
Commission.

     The Antitrust Division of the Department of Justice or the Federal Trade
Commission may challenge the merger on antitrust grounds either before or after
expiration of the waiting period. Accordingly, at any time before or after the
completion of the merger, either the Antitrust Division of the Department of
Justice or the Federal Trade Commission could take action under the antitrust
laws. Additionally, at any time before or after the completion of the merger,
notwithstanding that the applicable waiting period may have expired or been
terminated, any state or other person could take action under the antitrust laws
to enjoin the merger. A challenge to the merger could be made and if a challenge
is made, there can be no guarantee that Excite@Home would prevail.

     Neither Excite@Home nor iMALL is aware of any other material governmental
or regulatory approval required for completion of the merger, other than the
effectiveness of the registration statement of which this prospectus/proxy
statement is a part, and compliance with applicable corporate law of Nevada.

RESTRICTIONS ON SALES OF SHARES BY AFFILIATES OF IMALL AND EXCITE@HOME

     The shares of Excite@Home Series A common stock to be issued in the merger
will be registered under the Securities Act. These shares will be freely
transferable under the Securities Act, except for shares of Excite@Home Series A
common stock issued to any person who is an affiliate of either Excite@Home or
iMALL. Persons who may be deemed to be affiliates include individuals or
entities that control, are controlled by, or are under common control of either
company and may include some of their officers and directors, as well as their
principal stockholders. Affiliates may not sell their shares of Excite@Home
Series A common stock acquired in the merger except under (1) an effective
registration statement under the Securities Act covering the resale of those
shares, (2) an exemption under paragraph (d) of Rule 145 under the Securities
Act or (3) any other applicable exemption under the Securities Act.

LISTING ON THE NASDAQ NATIONAL MARKET OF EXCITE@HOME COMMON STOCK TO BE ISSUED
IN THE MERGER

     It is a condition to the closing of the merger that the shares of
Excite@Home Series A common stock to be issued in the merger be approved for
listing on the Nasdaq National Market.

DELISTING AND DEREGISTRATION OF IMALL COMMON STOCK AFTER THE MERGER

     After completion of the merger, iMALL common stock will be delisted from
the Nasdaq National Market and will be deregistered under the Securities
Exchange Act.

OPERATIONS AFTER THE MERGER

     After completion of the merger, iMALL will continue its operations as a
wholly-owned subsidiary of Excite@Home. The stockholders of iMALL will become
stockholders of Excite@Home, and their rights as stockholders will be governed
by the Excite@Home amended and restated certificate of incorporation, the
Excite@Home bylaws and the laws of the State of Delaware. See "Comparison of
rights of holders of iMALL common stock and Excite@Home common stock" on page
68.

NO OTHER NEGOTIATIONS INVOLVING IMALL

     Until the merger is completed or the merger agreement is terminated, iMALL
has agreed that it will not:

     - solicit, initiate, encourage or induce any Acquisition Proposal (as
       defined below);

     - participate in any discussions regarding or furnish any person any
       nonpublic information with respect to any Acquisition Proposal or take
       any other action to facilitate any inquiries or the making of any
       proposal that constitutes or may reasonably be expected to lead to any
       Acquisition Proposal;

     - engage in discussions with any person with respect to any Acquisition
       Proposal;

     - approve, endorse or recommend any Acquisition Proposal; or

     - enter into any letter of intent or similar document or any contract,
       agreement or commitment relating to any Acquisition Transaction (as
       defined below).

     However, iMALL may furnish information or enter into discussions with any
person or group submitting an unsolicited, written, bona fide Acquisition
Proposal that iMALL's board reasonably concludes may constitute a Superior Offer
(as defined below) if:

     - neither iMALL nor any of its representatives have violated its
       non-solicitation obligations described above;

     - iMALL's board concludes, after consultation with outside legal counsel,
       that the action is required in order for it to comply with its fiduciary
       obligations to its stockholders under applicable law;

     - prior to furnishing nonpublic information to or entering into discussions
       with a person or group iMALL notifies Excite@Home of the identity of the
       person or group as well as the material terms of the Acquisition
       Proposal;

     - iMALL gives Excite@Home at least three business days advance notice of
       its intent to furnish nonpublic information or enter into discussions
       with the person or group;

     - the person or group enters into an agreement with iMALL requiring any

     - iMALL furnishes to Excite@Home any nonpublic information that it
       furnishes to the person or group to the extent it had not previously
       provided the information to Excite@Home.

     iMALL has agreed to promptly inform Excite@Home of any Acquisition Proposal
or any request for nonpublic information or inquiry which iMALL reasonably
believes could lead to an Acquisition Proposal,including the identity of the
person or group making the Acquisition Proposal, request or inquiry and the
material terms of the Acquisition Proposal, request or inquiry. iMALL has agreed
to keep Excite@Home informed of the status and details of any Acquisition
Proposal.

     An ACQUISITION PROPOSAL is any offer or proposal relating to any
Acquisition Transaction, other than an offer or proposal from Excite@Home.

     An ACQUISITION TRANSACTION is any transaction involving any of the
following:

     - any acquisition or purchase of more than a 5% interest in the total
       outstanding voting securities of iMALL or any of its subsidiaries;

     - any tender offer or exchange offer, that, if consummated, would result in
       any person or group beneficially owning 5% or more of the total
       outstanding voting securities of iMALL or any of its subsidiaries;

     - any merger, consolidation, business combination or similar transaction
       involving iMALL;

     - any sale, lease outside the ordinary course of business, acquisition or
       disposition of more than 5% of the assets of iMALL; or

     - any liquidation or dissolution of iMALL.

     A SUPERIOR OFFER is an unsolicited, bona fide written offer made by a third
party to consummate any of the following transactions: (1) a merger or
consolidation involving iMALL under which the stockholders of iMALL immediately
preceding the transaction hold less than 50% of the equity interest in the
surviving or resulting entity of the transaction or (2) the acquisition by any
person or group, including by way of a tender offer or an exchange offer or a
two step transaction involving a tender offer followed with reasonable
promptness by a cash-out merger involving iMALL, directly or indirectly, of
ownership of 100% of the then outstanding shares of capital stock of iMALL, on
terms that iMALL's board determines, in its reasonable judgment, after
consultation with its financial adviser, to be more favorable to iMALL
stockholders than the terms of the merger.

     However, an offer shall not be deemed to be a Superior Offer if any
financing required to consummate the transaction contemplated by the offer is
not committed and is not likely in the reasonable judgment of iMALL's board to
be obtained by the third party on a timely basis.

     iMALL's board may, without breaching the merger agreement, change its
recommendation regarding the merger if a Superior Offer is made and iMALL
complies with other conditions in the merger agreement.

TREATMENT OF IMALL STOCK OPTIONS AND WARRANTS

     Upon completion of the merger, each outstanding option or warrant to
purchase iMALL common stock will be converted, in accordance with its terms,
into an option or warrant, as the case may be, to purchase the number of shares
of Excite@Home Series A common stock equal to 0.46 times the number of shares of
iMALL common stock which could have been obtained before the merger upon the
exercise of each option or warrant, rounded down to the nearest whole share. The
exercise price for the shares of Excite@Home Series A common stock will be equal
to the exercise price per share of iMALL common stock subject to the option or
warrant before conversion divided by 0.46, rounded up to the nearest whole cent.
In addition, as described under "Related Agreements -- First Data Warrant" on
page 61, a warrant to purchase 2,300,000 shares of Excite@Home Series A common
stock will be issued to First Data and a warrant to purchase shares of iMALL
common stock held by First Data will be amended upon the completion of the
merger.

     The other terms of each option and the iMALL option plans referred to above
under which the options were issued will continue to apply in accordance with
their terms, including any vesting provisions.

     Excite@Home will file a registration statement on Form S-8 for the shares
of Excite@Home Series A common stock issuable upon exercise of options under the
iMALL stock option plans and will maintain the effectiveness of this
registration statement for as long as any of the options remain outstanding.

     Excite@Home will also file, at its expense, a registration statement on
Form S-3 for the shares of Excite@Home Series A common stock issuable upon
exercise of warrants held by First Data as well as other holders of warrants to
purchase iMALL common stock to be assumed in the merger and will maintain the
effectiveness of this registration statement for a period of one year from the
date of the merger.

IMALL'S EMPLOYEE BENEFIT PLANS

     Excite@Home and iMALL will work together to agree upon mutually acceptable
employee benefit and compensation arrangements so as to provide benefits to
iMALL employees who become Excite@Home employees generally equivalent in the
aggregate to those provided to similarly situated employees of Excite@Home.
iMALL will terminate its severance, separation, retention and salary
continuation plans, programs or arrangements prior to the completion of the
merger.

DIRECTOR AND OFFICER INDEMNIFICATION

     Excite@Home will enforce the indemnification agreements between iMALL and
its directors and officers and for six years after the merger will maintain
provisions on indemnification in the surviving corporation's articles and bylaws
at least as favorable to the officers and directors as those in effect on the
date of the merger agreement. For six years after the merger, Excite@Home will
maintain directors' and officers' liability insurance covering those individuals
covered by iMALL's policy on the date of the merger agreement.

       except that the right to terminate the merger agreement under this
       provision by iMALL is not available to iMALL where the failure to obtain
       stockholder approval was caused by (1) the action or failure to act by
       iMALL and the action or failure to act constitutes a breach of the merger

       agreement;

          or exchange offer is first commenced a statement disclosing that iMALL
          recommends rejection of the tender or exchange offer.

     - by iMALL, upon a breach of any representation, warranty, covenant or
       agreement on the part of Excite@Home in the merger agreement, or if any
       of Excite@Home's representations or warranties are or become untrue so
       that the corresponding condition to completion of the merger would not be

circumstances which cause iMALL to pay the $2.5 million termination fee and

                               RELATED AGREEMENTS

     This section of the prospectus/proxy statement describes agreements related
to the merger agreement. While Excite@Home and iMALL believe that these
descriptions cover the material terms of these agreements, these summaries may
not contain all of the information that is important to you.

VOTING AGREEMENTS

     Excite@Home required First Data, Mark Comer, Cramer Rosenthal McGlynn Inc.,
Cramer Rosenthal McGlynn LLC, Marshall Geller, Anthony Mazzarella, Craig
Pickering, Richard Rogel, Richard Rosenblatt and Phillip Windley to enter into
voting agreements. These voting agreements require these persons to vote all of
the shares of iMALL common stock beneficially owned by them in favor of the
merger agreement, the merger and the amendment to the articles of incorporation
and against any proposal in opposition to or competition with the merger. Each
of these stockholders other than First Data also granted Excite@Home an
irrevocable proxy to vote his shares of iMALL common stock at the special
meeting.

     As of the record date, the iMALL stockholders who entered into voting
agreements collectively beneficially owned 8,231,934 shares of iMALL common
stock which represented approximately 41.9% of the outstanding iMALL common
stock.

     Each iMALL stockholder who is a party to a voting agreement, other than the
Cramer Rosenthal McGlynn entities, agreed not to sell or transfer the iMALL
stock and options beneficially owned by that person until the termination of the
voting agreement. In addition, Richard Rosenblatt and Phillip Windley also
agreed not to transfer or pledge 50% of their shares for nine months after the
completion of the merger and Anthony Mazzarella agreed to the same restriction
for six months.

     The voting agreements subject to the additional six and nine month transfer
restriction will terminate when the transfer restriction ends. All other voting
agreements will terminate upon the earlier of the termination of the merger
agreement or the completion of the merger.

AGREEMENTS RELATING TO THE FIRST DATA RELATIONSHIP

iMALL Development and Marketing Agreements

     When the merger agreement was signed, iMALL and First Data signed the First
Amended and Restated Development and Marketing Agreement, which is referred to
as the First Agreement, and the Second Amended and Restated Development and
Marketing Agreement, which is referred to as the Second Agreement. The First
Agreement went into effect when it was signed and will continue for at least ten
years unless it is terminated or replaced by the Second Agreement.

                                       58
<PAGE>   67

     Under the First Agreement, iMALL granted to First Data and its affiliates
(1) a perpetual, exclusive license to use the "FDMS gateway" (as described in
the agreement), and (2) a non-exclusive license during the term of the agreement
to use iMALL's electronic commerce tools and to license and market those tools
to third parties. In addition, iMALL must:

     - operate the FDMS gateway;

     - perform certain development activities;

     - operate and host applicable iMALL Internet sites;

     - promote First Data and its affiliates as a preferred provider of their
       respective services, and subject to existing contractual commitments, as
       the exclusive provider of on-line Internet accessible applications for
       such services;

     - not promote, nor permit its affiliates to promote, the services of any
       third party constituting a merchant acquiring business;

     - provide advertising opportunities to First Data, including advertising
       space and links on iMALL's web sites and the opportunity to solicit
       iMALL's merchants;

     - grant First Data the exclusive right to develop, broker and process
       private label or co-branded site-related transaction cards and share
       equally in the revenues from the development and brokerage of such cards;

     - provide its services so that the technology used is considered leading
       technology relative to other shopping portals and Internet mall hosting
       providers; and

       agreement.

     Under the First Agreement, First Data will:

       efforts; and

     - allow iMALL to use the gateway for purposes of meeting its obligations
       set forth in the agreement and for such other purposes as the parties may
       agree.

     First Data will pay to iMALL (1) a monthly fee for each merchant that uses
iMALL's electronic commerce tools and the FDMS gateway, (2) a one time fee for
the development of each merchant site, and (3) a monthly hosting fee for
maintaining each merchant site. First Data and iMALL shall share certain
advertising revenues after threshold revenue amounts are met. First Data is
entitled to a preferred pricing relationship under the agreement.

     The Second Agreement will replace the First Agreement when the merger is
completed. It is similar to the First Agreement except that it takes into
account Excite@Home's ownership of iMALL. The Second Agreement permits the
rebranding of certain iMALL products for Excite@Home and provides for specified
joint advertising and promotional activities. The Second Agreement also:

     - specifies that First Data's exclusive rights relating to transaction

       to promote the successor to iMALL.com and the Excite Shopping Service.

Capacity Reservation Agreement

     Excite@Home also entered into a Capacity Reservation Agreement with First
Data. This agreement will go into effect when the merger is completed and
requires Excite@Home to reserve sufficient resources to build and host
e-commerce enabled web sites. In each of the first three months after the
merger, if Excite@Home reserves resources for 33,333 web sites, First Data must
pay Excite@Home $1 million per month. In each of the following six months, if
Excite@Home reserves resources for 25,000 web sites, First Data will pay
$750,000 per month. In each of the following three months, if Excite@Home
reserves resources for 16,667 web sites, First Data will pay $500,000 per month.
In each case, these dollar amounts will be reduced by amounts paid by First Data
to iMALL during the same periods.

warrant to purchase 2,300,000 shares of Series A common stock for $36.96 per
share. The warrant will be exercisable when issued and will expire on October
30, 2003. When the merger agreement was signed, iMALL and First Data entered
into an amendment to the Investment Agreement, dated as of October 30, 1998,
between iMALL and First Data. The amendment provides that as long as the merger
agreement is in effect, iMALL will not issue to First Data the warrant to
purchase 5,000,000 shares of iMALL common stock issuable under the Investment
Agreement.

Registration Rights Agreement

     When the merger is completed, Excite@Home will sign a registration rights
agreement with First Data. This agreement will require Excite@Home to use its
commercially reasonable efforts to have the Securities and Exchange Commission
declare effective a registration statement registering the shares issuable under
the First Data warrant. This agreement will also require Excite@Home to keep the
registration statement effective for one year after the completion of merger.

REDEMPTION OF IMALL "SERIES A" WARRANTS

     iMALL currently has outstanding a series of warrants to purchase shares of
iMALL common stock at an exercise price of $3.20 per common share. These "Series
A" warrants are redeemable by iMALL at a redemption price of $0.40 per warrant.
On August 18, 1999, iMALL sent to holders of these warrants a notice of
redemption, which will result in the redemption and termination of these
warrants 30 days following the date of such notice. As a result, it is expected
that most of these warrants will be exercised prior to their redemption.

AMENDMENT TO IMALL "SERIES B" WARRANTS

     iMALL currently has outstanding warrants to purchase shares of iMALL common
stock at an exercise price of $3.20 per common share. These "Series B" warrants
contained extensive antidilution protection and registration rights provisions
for the holders. On July 12, 1999, holders of a majority of these warrants
agreed to amend their warrants to remove all registration rights provisions and
all antidilution protections except in the case of a stock split or stock
dividend or similar event. In return, Excite@Home agreed to file a registration
statement within 30 days of the completion of the merger to register the
Excite@Home Series A common stock issuable upon exercise of the warrants. iMALL
is seeking to have the remaining holders amend their "Series B" warrants before
completion of the merger and, as a result, it is expected that all or nearly all
of the "Series B" warrants will be amended prior to the completion of the
merger.

     Excite@Home and iMALL believe that iMALL common stock presently trades on
the basis of the value of the Excite@Home Series A common stock expected to be
issued in exchange for the iMALL common stock in the merger, discounted
primarily for the uncertainties associated with the merger. Apart from the
publicly disclosed information concerning Excite@Home which is included and
incorporated by reference in this prospectus/proxy statement, Excite@Home cannot
state with certainty what factors account for changes in the market price of the
Excite@Home Series A common stock.

     iMALL stockholders are advised to obtain current market quotations for
Excite@Home Series A common stock and iMALL common stock. No assurance can be
given as to the market prices of Excite@Home Series A common stock or iMALL
common stock at any time before the completion of the merger or as to the market
price of Excite@Home Series A common stock at any time after the merger. Because
the exchange ratio is fixed, the exchange ratio will not be adjusted to
compensate iMALL stockholders for decreases in the market price of Excite@Home
Series A common stock which could occur before the merger is completed. In the
event the market price of Excite@Home Series A common stock decreases or
increases prior to the consummation of the merger, the value of the Excite@Home
Series A common stock to be received in the merger in exchange for iMALL common
stock would correspondingly decrease or increase.

                            EXCITE@HOME COMMON STOCK

     This section of the prospectus/proxy statement describes certain
differences between iMALL common stock and Excite@Home Series A common stock.
While Excite@Home believes that the description covers the material differences
between the two, this summary may not contain all of the information that is
important to you. You should carefully read this entire document and the other
documents Excite@Home and iMALL refer to, including the certificates or articles
of incorporation, as applicable, and bylaws of each company for a more complete
understanding of the differences between iMALL common stock and Excite@Home
Series A common stock. You may obtain the information incorporated by reference
into this prospectus/proxy statement without charge by following the
instructions in the section entitled "Where you can find more information" on
page 87.

     After the merger, the former stockholders of iMALL, a Nevada corporation,
will become stockholders of Excite@Home, a Delaware corporation. The rights of
Excite@Home stockholders are governed by its certificate of incorporation, its
bylaws and the Delaware General Corporation Law, or the DGCL. The rights of
iMALL's stockholders are currently governed by its articles of incorporation,
its bylaws and the Nevada Revised Statutes, or the NRS. Upon completion of the
merger, the rights of iMALL stockholders who become Excite@Home stockholders
will be governed by the certificate of incorporation and bylaws of Excite@Home
and the DGCL. The following paragraphs summarize differences between the rights
of Excite@Home stockholders and iMALL stockholders under the certificate or
articles of incorporation and bylaws of Excite@Home and iMALL, as applicable, as
well as differences between the DGCL and the NRS.

CLASSIFICATION OF COMMON STOCK

     The Excite@Home certificate of incorporation provides for three series of
common stock, the Series A common stock, the Series B common stock and the
Series K common stock.

     The common stock of iMALL is not divided into separate classes or series.

VOTING

     Holders of Excite@Home Series A common stock and Series K common stock have
the right to one vote for each share of Series A or Series K stock held, and
holders of Excite@Home Series B common stock have the right to 10 votes for each
share of Series B stock held, on all matters presented to the Excite@Home
stockholders.

     Each iMALL stockholder has the right to one vote for each share of common
stock held by the stockholder.

SPECIAL MEETING OF STOCKHOLDERS

     Under the DGCL, a special meeting of stockholders may be called by the
board of directors or by any other person authorized to do so in the certificate
of incorporation or the bylaws. The Excite@Home bylaws provide that special
meetings of the stockholders may be called by a majority of the members of the
board of directors or upon written

                                       68
<PAGE>   77

request of the holders of not less than 10% of the total voting power of the
outstanding capital stock of Excite@Home entitled to vote at the meeting.

     The NRS is silent as to who may call a special meeting of stockholders. The
iMALL bylaws provide that special meetings of the stockholders may be called by
the president or by the board of directors, and shall be called by the president
at the request of the holders of not less than one-fourth of all outstanding
votes of the corporation entitled to be cast on any issue at the meeting.

RECORD DATE FOR DETERMINING STOCKHOLDERS

     The Excite@Home bylaws provide that the board of directors may fix a record
date which:

     - in the case of determination of stockholders entitled to vote at any
       meeting of stockholders or adjournment of any meeting, shall not be more
       than 60 nor less than 10 days before the date of the meeting;

     - in the case of determination of stockholders entitled to express consent
       to corporate action in writing without a meeting, shall not be more than
       10 days from the date upon which the resolution fixing the record date is
       adopted by the board of directors; and

     - in the case of any other action, shall not be more than 60 days prior to
       the action.

     The NRS provides that the board of directors may prescribe a period not
exceeding 60 days or fix a record date which shall not be more than 60 or less
than 10 days prior to the date of any meeting of the stockholders, during which
period no transfer of stocks on the books of the corporation may be made as the
date as of which stockholders entitled to notice of and to vote at that meeting
must be determined.

     The Excite@Home bylaws provide that if the board of directors do not fix a
record date in the manner described above, then:

     - the record date for determining stockholders entitled to notice of or to
       vote at a meeting of stockholders shall be at the close of business on
       the day next preceding the day on which notice is given, or, if notice is
       waived, at the close of business on the day next preceding the day on
       which the meeting is held;

     - the record date for determining stockholders entitled to express consent
       to corporate action in writing and without a meeting, when no prior
       action by the board of directors is necessary, shall be the day on which
       the first written consent is made; and

     - the record date for determining stockholders for any other purpose shall
       be at the close of business on the same day on which the board of
       directors adopts the related resolution.

     The NRS provides that if the board of directors does not fix a record date
in the manner described above, then the record date for determining stockholders
entitled to notice of and to vote at a meeting of stockholders shall be at the
close of business on the day before the day on which notice is given to the
stockholders.

<PAGE>   78

ELECTION OF DIRECTORS

     The Excite@Home certificate of incorporation provides that:

     (1) so long as there are at least 10,000,000 shares of Series B common
         stock outstanding, the holders of Series B common stock, voting
         separately as a single series, shall be entitled to elect five
         directors to the board of directors; and

     (2) in the event that holders of Series B common stock are entitled to
         elect any directors, then so long as there are any shares of Series A
         common stock outstanding, the holders of Series A common stock, voting
         separately as a single series, shall be entitled to elect two directors
         to the board of directors. The directors elected by the holders of
         Series A common stock must not be (1) an officer, other than a Vice
         Chairman, of, or employed by, Excite@Home or its subsidiaries or (2) an
         affiliate or associate of Cox Enterprises, Inc., Comcast Corporation or
         TCI Internet Holdings, or any of their affiliates, other than
         Excite@Home and its subsidiaries. If the total number of directors
         constituting the board of directors exceeds the number of directors
         that the Series A common stock and Series B common stock are entitled
         to elect, then any additional directors shall be elected by the holders
         of all series of common stock, and any preferred stock entitled to
         vote, voting together as a single class.

     The holders of iMALL common stock elect all members of iMALL's board of
directors; there is no series vote.

NUMBER OF DIRECTORS

     Both the DGCL and the NRS provide that the board of directors must consist
of at least 1 director, with the corporation having the option of specifying a
fixed or a variable number of directors within a fixed range. The Excite@Home
certificate of incorporation provides that the board of directors shall consist
of not fewer than three and not more than seventeen directors, with the exact
number to be specified by the board of directors. The total number of directors
may not be less than (1) the total number of directors that the holders of
Series A and Series B common stock are entitled to elect and (2) any directors
that the holders of any series of preferred stock, voting as a separate series
and not with the common stock, are entitled to elect.

     The iMALL bylaws provide that the board of directors shall consist of
between one and ten directors; provided, however, that if iMALL has less than
seven stockholders entitled to vote for the election of directors, the board of
directors may consist of a number of individuals equal to or greater than the
number of those stockholders. The bylaws further provide that until First Data
no longer has the right to designate members of iMALL's board of directors under
the terms of the Stockholders Agreement among iMALL, First Data and certain
stockholders of iMALL, the total number of authorized directors will not be less
than seven nor more than ten. The number of directors within these limits will
be determined by the board of directors without the participation of the
directors appointed to the board by First Data. However, the board of directors
may not authorize or approve any recommendation to the stockholders to change
the number of directors constituting the entire board without the approval of a
majority of the FDMS Committee, which is comprised exclusively of each of the
directors appointed by First Data.

                                       70
<PAGE>   79

REMOVAL OF DIRECTORS

     The DGCL provides that for corporations such as Excite@Home which neither
have cumulative voting nor a classified board of directors, any director or the
entire board may be removed, with or without cause, by the holders of a majority
of the shares then entitled to vote at an election of directors. The Excite@Home
certificate of incorporation, however, provides that any director elected by the
holders of Series A common stock or Series B common stock may be removed from
office without cause solely by the vote of the holders of a majority of the
outstanding shares of the applicable series of common stock that elected the
director.

     The NRS provides that any director or one or more of the incumbent
directors may be removed from office by the vote of stockholders representing
not less than two-thirds of the voting power of the issued and outstanding stock
entitled to vote. The iMALL bylaws further provide that the stockholders may
remove one or more directors, with or without cause, at a meeting called for
that purpose if notice has been given that a purpose of the meeting is the
removal of the director(s). If the director is elected by a voting group of
stockholders, only the stockholders of that voting group may participate in the
vote to remove the director(s). Furthermore, the board of directors may not call
a special meeting to vote on the removal of a director appointed by First Data
unless the board of directors has first determined, by the affirmative vote of
at least a majority of the members of the entire board of directors and with the
concurrence of the FDMS Committee that there exists cause to remove the First
Data director from the board.

BOARD OF DIRECTORS VACANCIES

     Under the DGCL, vacancies and newly created directorships may be filled by
a majority of the directors then in office, even though less than a quorum,
unless (1) otherwise provided in the certificate of incorporation or bylaws of
the corporation or (2) the certificate of incorporation directs that a
particular class is to elect the director, in which case any other directors
elected by the class, or a sole remaining director, may fill the vacancy. The
Excite@Home certificate of incorporation further that any vacancy in the office
of a director elected by the holders of Series A common stock or Series B common
stock common stock shall be filled by the vote of the holders of a majority of
the shares of the applicable series of common stock that originally elected the
director; provided, however, that if there is a vacancy in the office of one of
the two directors elected by the holders of Series A common stock, the remaining
director elected by the holders of Series A common stock shall have the power to
fill the vacancy.

     The NRS provides that all vacancies, including those caused by an increase
in the number of directors, may be filled by a majority of the remaining
directors, though less than a quorum, unless it is otherwise provided in the
articles of incorporation. The iMALL bylaws further provide that vacancies on
the board of directors may be filled by the stockholders. During any time that
the stockholders fail or are unable to fill a vacancy, then and until the
stockholders act, the board of directors may fill the vacancy. In the event of
any vacancy in a directorship originally appointed by First Data, the FDMS
Committee shall have the exclusive authority to fill that vacancy.

SPECIAL MEETINGS OF THE BOARD OF DIRECTORS

     The Excite@Home bylaws provide that the chairman of the board or a majority
of the members of the board of Excite@Home may call a special meeting of the
board of

                                       71
<PAGE>   80

directors. The bylaws require that written notice of the time and place of the
meeting be given at least ten days before the meeting if the notice is mailed,
or at least three days before the meeting if notice is given by facsimile,
telegram, cable or personal service, unless the notice requirement is waived in
writing by each member of the board of directors. Any and all business may be
transacted at a special meeting of the board of directors without specification
of the business in the notice. However, notice of a special meeting to discuss
(1) certain actions requiring a supermajority or unanimous vote of the directors
elected by the holders of the Series B common stock or (2) transactions between
Excite@Home and any holder of more than 5% of the voting power of Excite@Home,
or any affiliate of the 5% holder, shall include a reasonably detailed
description of the matter(s).

     The iMALL bylaws provide that the president or any director may call a
special meeting of the board of directors.

BOARD ACTION -- GENERALLY

     The Excite@Home certificate of incorporation provides that except for
certain actions involving related parties or actions that have supermajority or
unanimous voting requirements, as explained below, board action requires the
vote of (1) a majority of the directors present at a meeting at which a quorum
is present or a written consent to the action executed by all members of the
board of directors and (2) so long as TCI beneficially owns at least 15,400,000
shares of Series B common stock and securities representing a majority of the
voting power of Excite@Home, 75% of the directors elected by the holders of
Series B common stock (66 2/3% if there are only three Series B directors and
100% if there are only two).

     The NRS provides that the act of directors holding a majority of the voting
power of the directors, present at a meeting at which a quorum is present, is
the act of the board of directors. Any action required or permitted to be taken
at a meeting of the board of directors may be taken without a meeting if, before
or after the action, a written consent to that action is signed by all the
members of the board.

BOARD ACTION -- TRANSACTIONS WITH RELATED PARTIES

     The Excite@Home certificate of incorporation provides that, with respect to
certain transactions between Excite@Home and any holder of more than 5% of the
voting power of Excite@Home, or any affiliate of the 5% holder, board approval
requires the vote of each of the following:

     - a majority of the directors present at a meeting at which a quorum is
       present or a written consent to the action executed by all members of the
       board of directors; and

     - so long as the holders of Series B common stock are entitled to elect at
       least one Series B director, the vote of either:

       - 75% of the total number of number of directors who were elected by the
         holders of Series B common stock, regardless of whether the directors
         are disinterested in the transaction, and a majority of all directors
         elected by the holders of the Series B common stock who are
         disinterested in the transaction unless the transaction is of a type
         that requires a supermajority or unanimous vote of the Series B
         directors; or

                                       72
<PAGE>   81

       - all of the directors who were elected by the holders of Series B common
         stock, regardless of whether the directors are disinterested in the
         transaction.

     The iMALL articles of incorporation and bylaws do not contain any similar
provisions regarding transactions with related parties.

BOARD ACTION -- SUPERMAJORITY REQUIREMENT

     So long as the holders of Series B common stock are entitled to elect at
least one Series B director, the vote or written consent of a supermajority of
75%, rounded up to the nearest whole number of directors of the total number of
the directors elected by the holders of Series B common stock, voting separately
from the other directors of Excite@Home, are required to approve certain
actions, including the following:

     - mergers of Excite@Home or a controlled affiliate of Excite@Home;

     - acquisitions of stock or assets for a price in excess of 20% of the fair
       market value of Excite@Home's assets;

     - dispositions of Excite@Home's assets having an aggregate value in excess
       of 50% of the fair market value of Excite@Home's assets;

     - acquisitions of stock or assets in exchange for more than 16 2/3% of
       Excite@Home's capital stock;

     - the approval or removal of the Chief Executive Officer of Excite@Home;

     - the voluntary dissolution or liquidation of Excite@Home or the initiation
       of voluntary bankruptcy proceedings;

     - certain amendments to the bylaws or certificate of incorporation of
       Excite@Home;

     - the creation of classes of stock of Excite@Home entitled to special
       voting rights;

     - an increase in the shares of Series A common stock issued or reserved for
       issuance to management in excess of a specified amount; and

     - the declaration or payment of certain dividends or distributions to
       controlled affiliates of Excite@Home.

     If the action requiring supermajority approval is a transaction with a
related party, the transaction must be approved by either 75%, rounded up to the
nearest whole number of directors, of the Series B directors who are
disinterested in the transaction, or a majority of the entire board of directors
and all Series B directors regardless of whether they are disinterested
directors.

     The iMALL articles of incorporation and bylaws do not contain any similar
provisions regarding transactions requiring the approval of a supermajority of
the board of directors.

                                       73
<PAGE>   82

BOARD ACTION -- UNANIMITY REQUIREMENT

     The vote or written consent of 100% of the total number of Excite@Home
directors elected by the holders of Series B common stock, regardless of whether
the directors are disinterested directors, voting separately from the other
directors of Excite@Home are required to approve certain actions, including the
following:

     - any amendments to the Excite@Home certificate of incorporation regarding
       the items which require supermajority or unanimous approval;

     - any increase in the number of directors to be elected by the holders of
       Series B common stock common stock;

     - any modification of the rights of the holders of Series B common stock or
       Series K common stock to designate and elect directors; and

     - the appointment of any directors to the .Com committee, whose function is
       explained in the following subheading.

     The iMALL articles of incorporation and bylaws do not contain any similar
provisions regarding transactions requiring the approval of the entire board of
directors.

ACTION BY COMMITTEES

     Both the Excite@Home bylaws and the iMALL bylaws authorize their respective
board of directors to establish committees by resolution setting forth the
powers and duties of these committees. The DGCL and NRS both state that these
committees have and may exercise the power of the board of directors in the
management of the business and affairs of the corporation. The DGCL states,
however, that no committee may (1) approve, adopt or recommend to the
stockholders any action or matter that is expressly required by the DGCL to be
submitted to the stockholders for approval or (2) adopt, amend or repeal any
bylaw of the corporation. The iMALL bylaws provide that, in addition to the two
items prohibited by the DGCL, committees may not:

     - authorize distributions;

     - fill vacancies on the board of directors or on any committee;

     - amend the articles of incorporation;

     - approve a plan of merger not requiring stockholder approval;

     - authorize or approve reacquisition of shares, except according to a
       formula or method prescribed by the board; or

     - authorize or approve the issuance or sale of shares or determine the
       designation and relative rights, preferences and limitations of a class
       or series of shares, unless the board has authorized the committee to do
       so within certain prescribed limits.

     The Excite@Home certificate of incorporation establishes a special
committee: the .Com committee. The .Com committee has the power to approve the
execution, delivery and performance of certain agreements between Excite@Home
and third parties which provide or promote content for Excite@Home's network
where these third parties are holders of more than 5% of the voting power of
Excite@Home, or are an affiliate of a 5%

                                       74
<PAGE>   83

or greater stockholder. Except by vote of a majority of the board of directors,
including all of the Series B directors, the board of directors may not:

     - rescind or modify any action or determination made by the .Com committee

     - remove any member of the .Com committee;

     - amend any provisions of Excite@Home's bylaws or certificate of
       incorporation regarding the .Com committee; or

     - dissolve or terminate the .Com committee.

     Any action taken by the .Com committee must be approved by either a
majority of the members of the committee or a written consent to the action
executed by all members of the committee.

     In the case of action by any committee of the Excite@Home board of
directors other than the .Com committee, the approval of that action must be by
both of the following:

     - either a majority of the members of the committee present at a meeting at
       which a quorum is present or a written consent to that action executed by
       all members of the committee; and

     - so long as the holders of Series B common stock are entitled to elect at
       least one director and TCI Internet Holdings, Inc. holds at least
       15,400,000 shares of Series B common stock and securities representing a
       majority of the outstanding voting power of Excite@Home, 75% of the total
       number of directors elected by the holders of Series B common stock.

     The iMALL bylaws currently provide for two special committees, the FDMS
Committee and the Company Committee. The FDMS Committee is comprised exclusively
of each of the directors that are appointed to iMALL's board of directors by
FDMS. The Company Committee is comprised of directors named by a majority vote
of the board of directors, excluding the FDMS appointed directors and any other
members of the board of directors who are affiliates of FDMS. Prior to each
meeting of the stockholders at which directors are to be elected, the FDMS
Committee and the Company Committee each designate persons as nominees for
election as directors to iMALL's board.

APPROVAL OF THIRD-PARTY CONTENT TRANSACTIONS

     The Excite@Home certificate of incorporation provides that with respect to
the execution, delivery and performance of certain agreements between
Excite@Home and third parties which provide or promote content for Excite@Home's
network, these agreements may be approved by Excite@Home by any one of the
following methods:

     - approval by the authorized officers of Excite@Home, without the approval
       of the board of directors, if the agreements contain Excite@Home's
       standard terms and conditions for agreements of that type;

     - approval of a majority of the .Com committee; or

     - approval of a majority of the board of directors, including all directors
       elected by the holders of Series B common stock.

                                       75
<PAGE>   84

     The iMALL articles of incorporation and bylaws do not contain a similar
provision regarding the approval of specific agreements.

PREFERRED STOCK

     The Excite@Home certificate of incorporation authorizes the board of
directors to issue up to 9,650,000 shares of preferred stock in one or more
series and to fix the designations, preferences, powers and rights of the shares
to be included in each series. The iMALL articles of incorporation authorizes
the board of directors to issue up to 10,000,000 shares of preferred stock in
one or more series and to fix the designations, preferences, powers and rights
of the shares to be included in each series.

     The Excite@Home certificate of incorporation provides that, except to the
extent otherwise provided in the resolution(s) providing for the issuance of any
series of preferred stock, the holders of shares of the series shall have no
voting rights except as provided by the DGCL. Further, unless otherwise
expressly provided in the certificate of designations for a series of preferred
stock, no consent or vote of the holders of shares of preferred stock shall be
required to amend the Excite@Home certificate of incorporation to increase or
decrease the number of authorized shares of preferred stock or any series of
preferred stock.

CONVERSION RIGHTS

     The Excite@Home certificate of incorporation provides that each share of
Series B common stock and Series K common stock is convertible, at the option of
the holder, into one share of Series A common stock. Shares of Series A common
stock are not convertible into shares of Series B or Series K common stock.

     The iMALL articles of incorporation and bylaws do not contain a comparable
provision regarding conversion rights.

SHARE DIVIDENDS

     The Excite@Home certificate of incorporation provides that if a
distribution in the form of securities of Excite@Home is paid to the holders of
Series A common stock, Series B common stock or Series K common stock, the
distribution must be made only by one of the following methods:

     - Excite@Home may distribute shares of Series A common stock to holders of
       Series A common stock, Series B common stock and Series K common stock on
       an equal per share basis;

     - Excite@Home may distribute shares of Series A common stock to holders of
       Series A common stock, shares of Series B common stock to holders of
       Series B common stock and shares of Series K common stock to holders of
       Series K common stock, with these distributions to be made on an equal
       per share basis; and

     - Excite@Home may distribute any other class or series of securities of
       Excite@Home, on an equal per share basis. to holders of Series A common
       stock, Series B common stock and Series K common stock, with certain
       restrictions.

     The iMALL articles of incorporation and bylaws do not contain a comparable
provision regarding share dividends.

                                       76
<PAGE>   85

INDEMNIFICATION

     The Excite@Home certificate of incorporation provides that its directors
and officers shall be indemnified to the fullest extent authorized by Delaware
law against all expenses, liabilities and losses reasonably incurred by that
person in connection with any action, proceeding or suit brought against that
person by reason of the fact that he or she is or was a director or officer of
Excite@Home or is or was serving at the request of Excite@Home as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or similar entity.

     The iMALL articles of incorporation and bylaws provide that its directors
and officers shall be indemnified to the fullest extent authorized by Nevada law
against all expenses, liability and losses reasonably incurred by that person in
connection with any threatened, pending or completed action or suit, including
the amount of judgments, amounts paid in compromise settlements and amounts paid
for services of counsel and other related expenses, by reason of the fact that
he or she was a director or officer of iMALL or is or was serving at the request
of iMALL as a director, officer, employee, agent, partner or fiduciary of, or in
any other capacity for, another corporation, partnership, joint venture, trust
or similar entity.

     Neither Excite@Home nor iMALL is permitted to indemnify its officers or
directors if the expenses, liability and losses incurred are the result of the
individual's negligence or misconduct; the person must have acted in good faith
and in a manner the person believed to be not opposed to the best interest of
the corporation. The iMALL bylaws further provide that iMALL may, by action of
its board of directors, indemnify employees and other persons to the same extent
as directors and officers.

     Both the DGCL and NRS provide that a corporation shall indemnify the
expenses incurred by any director, officer, employee or agent that has been
successful on the merits or otherwise in defense of any action, suit or
proceeding. The DGCL and NRS further provide that indemnification may be made by
a corporation upon a determination that indemnification of a former or present
director, officer, employee or agent is proper because that person acted in good
faith and in a manner the person believed to be in or not opposed to the best
interest of the corporation. Under the DCGL, this determination must be made by
(1) a majority vote of disinterested directors, even if less than a quorum, (2)
a committee of disinterested directors designated by a majority vote of the
disinterested directors, even if less than a quorum, (3) independent legal
counsel in a legal opinion if there are no disinterested directors or (4) the
stockholders. Under the NRS, this determination must be made by (1) the
stockholders, (2) the board of directors by a majority vote of a quorum
consisting of directors who were not parties to the action, suit or proceeding,
(3) by independent legal counsel in a written opinion of a majority vote if a
quorum consisting of directors who were not parties to the action, suit or
proceeding so orders or (4) by independent legal counsel in a written opinion if
a quorum consisting of directors who were not parties to the action, suit or
proceeding cannot be obtained.

LIMITATION ON LIABILITY

     The DGCL permits corporations to adopt a provision in their certificate of
incorporation eliminating the liability of a director to the corporation or its
stockholders for monetary damages for breach of the director's fiduciary duty of
care. With certain exceptions, the NRS permits corporations to adopt similar
provisions in their articles of incorporation eliminating the liability of a
director to the corporation or its stockholders for

                                       77
<PAGE>   86

monetary damages for breach of the director's fiduciary duty. The Excite@Home
certificate of incorporation provides that, to the fullest extent permitted by
Delaware law, a director of Excite@Home shall not be liable to Excite@Home or
any of its stockholders for monetary damages for breach of fiduciary duty as a
director.

     The iMALL articles of incorporation contain a similar provision limiting
the prospective liability of directors.

DIVIDENDS/DISTRIBUTIONS

     Subject to any restrictions contained in a corporation's certificate of
incorporation, the DGCL generally provides that a corporation may declare and
pay dividends out of surplus, defined as net assets minus stated capital, or,
when no surplus exists, out of net profits for the fiscal year in which the
dividend is declared or for the preceding fiscal year. Dividends may not be paid
out of net profits if the capital of the corporation is less than the amount of
capital represented by the issued and outstanding stock of all classes having a
preference upon the distribution of assets. The Excite@Home certificate of
incorporation contains no restrictions on the declaration or payment of
dividends. The Excite@Home certificate of incorporation provides that whenever a
dividend is paid to the holders of one series of common stock, the other series
of common stock are to receive a dividend per share equal to the dividend per
share paid to the first series of common stock.

     The NRS provides that no distribution to stockholders may be made if the
corporation would not be able to pay its debts as they become due in the usual
course of business or the corporation's total assets would be less than the sum
of its total liabilities plus the amount that would be needed, if the
corporation were to be dissolved at the time of distribution, to satisfy the
preferential rights upon dissolution of stockholders whose preferential rights
are superior to those receiving the distribution. A distribution to stockholders
under the NRS may be in the form of a declaration or payment of a dividend, a
purchase, redemption or other acquisition of shares, a distribution of
indebtedness or otherwise. The NRS provides that in declaring and paying
distributions, a director is fully protected in relying in good faith upon the
books of account of the corporation or statements prepared by any of its
officials as to the value and amount of the assets, liabilities or net profits
of the corporation, or any other facts pertinent to the existence and amount of
money from which distributions may properly be declared.

     Neither the iMALL articles of incorporation nor its bylaws contain any
provisions with regard to distributions.

LIQUIDATION

     Under the DGCL, a dissolution must be consented to in writing by
stockholders holding 100% of the total voting power or the dissolution must be
initiated by the board of directors and approved by the holders of a majority of
the outstanding voting shares of the corporation. Under the NRS, unless
otherwise provided in the corporation's articles of incorporation, stockholders
holding a majority of the total voting power may authorize a corporation's
dissolution.

     The Excite@Home certificate of incorporation provides that in the event of
a liquidation, dissolution or winding up of Excite@Home, whether voluntary or
involuntary, after payment of any amounts owed to creditors subject to
preferences of any outstanding preferred stock, and any preferential amounts, if
any, owed to any series of preferred stock,

                                       78
<PAGE>   87

the holders of Series A common stock, Series B common stock and Series K common
stock and the holders of any class or series of preferred stock then outstanding
shall share equally, on a share for share basis on an as converted to common
stock basis, in the assets of Excite@Home remaining for distribution to its
stockholders.

     In the event of a liquidation, dissolution or winding up of iMALL, after
payment of or adequately provide for any amounts owed to creditors, the
remaining assets of iMALL will be divided equally, on a share for share basis,
to the holders of the common stock of iMALL.

AMENDMENT OF CERTIFICATE OR ARTICLES OF INCORPORATION

     Under both the DGCL and the NRS, unless the certificate or articles of
incorporation or bylaws provide otherwise, amendments of the certificate or
articles of incorporation generally require the approval of the holders of a
majority of the outstanding shares entitled to vote. The DGCL provides that if
any amendment would increase or decrease the number of authorized shares of any
class or series or the par value of such shares or would adversely affect the
shares of such class or series, a majority of the outstanding shares of that
class or series would have to approve the amendment. The NRS provides that if
any proposed amendment, including a proposed increase or decrease in the number
of authorized shares, would alter or change any preference or any relative or
other right given to any class or series of outstanding shares, then a majority
of the outstanding shares of the affected class or series would have to approve
the amendment.

AMENDMENT OF BYLAWS

     The DGCL provides that the stockholders entitled to vote shall have the
power to adopt, amend or repeal the bylaws of a corporation. The Excite@Home
bylaws provide that the board of directors or stockholders holding not less than
66 2/3% of the total voting power of the then outstanding capital stock of
Excite@Home entitled to vote thereon may adopt, amend or repeal the bylaws.

     The iMALL articles of incorporation provides that the board of directors
has the power to make and alter, or amend the bylaws. The iMALL bylaws provide
that the board of directors may amend or repeal the bylaws at any time unless
(1) the articles of incorporation or the NRS reserve the power exclusively to
the stockholders in whole or part, (2) the stockholders in approving, amending
or repealing a particular bylaw provide expressly that the board of directors
may not amend or repeal that bylaw or (3) the bylaw either establishes, amends
or deletes a greater stockholder quorum or voting requirements. An amendment
which changes the voting or quorum requirement for the board must meet the same
quorum requirement and be adopted by the same vote and voting groups required to
take action under the quorum voting requirement then in effect or proposed to be
adopted, whichever is greater.

STOCKHOLDER VOTING WITH RESPECT TO MERGERS

     Both the NRS and the DGCL generally require that a majority of the
stockholders of the merging corporations approve statutory mergers. The DGCL
does not require a stockholder vote of the surviving corporation in a merger,
unless the corporation provides otherwise in its certificate of incorporation,
if:

     - the merger agreement does not amend the existing certificate of
       incorporation;

     - each share of the corporation outstanding before the merger is an
       identical outstanding or treasury share of the surviving corporation
       after the merger; and

     - the number of shares to be issued by the surviving corporation in the
       merger does not exceed 20% of the shares of the corporation outstanding
       immediately prior to the merger.

     The NRS provides that the vote of the stockholders of a surviving
corporation on a plan of merger is not required if:

     - the articles of incorporation of the surviving corporation will not
       differ from the articles before the merger;

     - each stockholder of the surviving corporation whose shares were
       outstanding immediately before the effective date of the merger will hold
       the same number of shares, with identical designations, preferences,
       limitations and relative rights immediately after the merger;

     - the number of voting shares outstanding immediately after the merger,
       plus the number of voting shares issued as a result of the merger, either
       by the conversion of securities issued as a result of the merger or then
       exercise of rights and warrants issued as a result of the merger, will
       not exceed by more than 20% the total number of voting shares of the
       surviving corporation outstanding immediately prior to the merger; and

     - the number of participating shares outstanding immediately after the
       merger, plus the number of participating shares issuable as a result of
       the merger, either by the conversion of securities issued as a result of
       the merger or the exercise of rights and warrants issued as a result of
       the merger, will not exceed by more than 20% the total number of
       participating shares outstanding immediately prior to the merger.

     The DGCL generally does not require class voting, except in certain
transactions involving an amendment to the certificate of incorporation which
adversely affects a specific class of shares. The NRS provides that separate
voting by class is required (1) on a plan of merger if the plan contains a
provision that, if contained in the proposed amendment to the articles of
incorporation, would entitle particular stockholders to vote as a class on the
proposed amendment or (2) on a plan of exchange by each class or series of
shares included in the exchange, with each class or series constituting a
separate voting class.

APPRAISAL AND DISSENTERS' RIGHTS

     Under both the NRS and the DGCL, a stockholder of a corporation
participating in certain major corporate transactions may, under varying
circumstances, be entitled to appraisal or dissenters' rights under which such
stockholder may receive cash in the

                                       80
<PAGE>   89

amount of the fair market value of his or her shares in lieu of the
consideration he or she would otherwise receive in the transaction.

     Under the DGCL, appraisal rights are not available

     - with respect to the sale, lease or exchange of all or substantially all
       of the assets of a corporation;

     - with respect to a merger or consolidation by a corporation the shares of
       which are either listed on a national securities exchange or are held of
       record by more than 2,000 holders if the stockholders receive only shares
       of the surviving corporation or shares of any other corporation which are
       either listed on a national securities exchange or held of record by more
       than 2,000 holders, plus cash in lieu of fractional shares; or

     - to stockholders of a corporation surviving a merger if no vote of the
       stockholders of the surviving corporation is required to approve the
       merger.

     The NRS provides that dissenters' rights are not available with respect to
a merger or exchange by a corporation the shares of which are listed on a
national securities exchange, included in the national market system by the
National Association of Securities Dealers, Inc. or held of record by more than
2,000 holders unless the articles of incorporation of the corporation issuing
the shares provides otherwise or the holders of the class or series are required
under the plan of merger or exchange or to accept for the shares anything other
than cash or owner's interests of the surviving entity or any other entity which
was either listed on a national securities exchange, included in the national
market system by the National Association of Securities Dealers or held of
record by more than 2,000 holders.

STOCKHOLDER APPROVAL OF CERTAIN BUSINESS COMBINATIONS

     Sections 78.411 to 78.444 of the NRS prohibit a Nevada corporation from
engaging in certain "combinations" with an "interested stockholders." With
certain exceptions, an interested stockholder is a person or group who or which
owns 10% or more of the corporation's outstanding voting stock, including any
rights to acquire stock under an option, warrant, agreement, arrangement or
understanding, or upon the exercise of conversion or exchange rights, and stock
with respect to which the person has voting rights only, or is an affiliate or
associate of the corporation and was the owner of 10% or more of the
corporation's voting stock at any time within the previous three years. For
purposes of Sections 78.411 to 78.444, the term "combination" is defined broadly
to include:

     - mergers or consolidations with the interested stockholder or any other
       corporation which is, or after the merger or consolidation would be, an
       affiliate or associate of the interested stockholder;

     - sales or other dispositions to the interested stockholder, or any
       affiliate or associate of the interested stockholder, of assets of the
       corporation or a subsidiary equal to (i) 5% or more of the aggregate
       market value of the corporation's consolidated assets or its outstanding
       stock or (2) 10% or more of the corporation's consolidated earning power
       or net income;

     - the issuance or transfer by the corporation or a subsidiary of stock of
       the corporation or the subsidiary having an aggregate market value equal
       to 5% or more of the aggregate outstanding stock of the corporation to
       the interested stockholder,

                                       81
<PAGE>   90

       except for the exercise of warrants or rights to purchase shares offered,
       or a dividend or distribution paid or made, pro rata to all stockholders
       of the corporation;

     - the adoption of any plan of proposal for the liquidation or dissolution
       of the corporation proposed by, or under agreement with, the interested
       stockholder or any affiliate or associate of the interested stockholder;

     - a reclassification, recapitalization, merger, consolidation or other
       similar transaction, whether or not with, proposed by or under agreement
       with the interested stockholder, which has the effect of increasing the
       proportionate share of the outstanding shares of any class or series of
       the corporation's outstanding stock owned by the interested stockholder
       or any affiliate or associate of the interested stockholder, except for
       immaterial changes because of adjustments of fractional shares; or

     - receipt by the interested stockholder, except proportionately as a
       stockholder, directly or indirectly, of any loans, advances, guarantees,
       pledges or other financial benefits provided by or through the
       corporation or a subsidiary.

     Sections 78.411 to 78.444 prohibit combinations with an interested
stockholder for three years from the date of the interested stockholder's
acquisition of the shares of the corporation unless prior to the date on which
the person becomes an interested stockholder, the board of directors approves
the combination or the transaction which resulted in the person becoming an
interested stockholder.

     Furthermore, sections 78.411 to 78.444 prohibit combinations with an
interested stockholder after the expiration of the three-year moratorium unless:

     - the holders of stock representing a majority of the outstanding voting
       power of the corporation not beneficially owned by the interested
       stockholder proposing the combination, or any affiliate or associate of
       the interested stockholder, approves the combination at a meeting called
       for that purpose no earlier than three years after the interested
       stockholder's date of acquiring the shares; or

      - the aggregate amount of cash and the market value, as of the date of the
        consummation of the combination, of the consideration other than cash to
        be received per share by all of the holders of common stock not
        beneficially owned by the interested stockholder is at least equal to
        the higher of (A) the highest price per share paid by the interested
        stockholder, at a time when he was the beneficial owner of 5% or more of
        the outstanding voting stock of the corporation, for any common shares
        of the same class or series acquired by him within three years
        immediately before the date of the announcement with respect to the
        combination or within three years immediately before the transaction in
        which he became an interested stockholder, whichever is higher, plus
        compounded interest or (B) the market value per share of common stock on
        the date of the announcement with respect to the combination or the
        interested stockholder's date of acquiring shares, whichever is higher,
        plus interest; and

      - the aggregate amount of cash and the market value, as of the date of the
        consummation of the combination, of the consideration other than cash to
        be received per share by all of the holders of shares other than common
        stock not beneficially owned by the interested stockholder is at least
        equal to the higher of (A) the highest price per share paid by the
        interested stockholder, at a time when he was the beneficial owner of 5%
        or more of the outstanding voting stock of the corporation, for any
        common shares of the same class or series acquired by

                                       82
<PAGE>   91

        him within three years immediately before the date of the announcement
        with respect to the combination or within three years immediately before
        the transaction in which he became an interested stockholder, whichever
        is higher, plus compounded interest, (B) the highest preferential amount
        per share to which the holders of shares of the class or series of
        shares are entitled in the event of any voluntary liquidation,
        dissolution or winding up of the corporation, plus the aggregate amount
        of any dividends declared or due to which the holders are entitled
        before payment on another class or series of shares or (C) the market
        value per share of the class or series of stock on the date of the
        announcement with respect to the combination or the interested
        stockholder's date of acquiring shares, whichever is higher, plus
        interest.

     Although Nevada corporations may elect to opt out of sections 78.411 to
78.444 of the NRS by amending their articles of incorporation, such amendment
would not be effective until 18 months after the stockholder vote approving it.
As a result, iMALL did not so elect and therefore is subject to these
provisions.

     Sections 78.378 through 78.3793 of the NRS further regulate tender offers
and business combinations involving Nevada corporations by providing that any
acquisition by a person, either directly or indirectly, of ownership of, or the
power to direct the voting of 20% or more of the outstanding voting securities
("Control Shares") of a corporation is an "Acquisition of a Controlling
Interest." Before the Control Shares may be voted, such an acquisition must be
approved by the holders of a majority of the voting power of the corporation,
excluding those shares as to which any interested stockholder exercises voting
rights, or, if the acquisition will result in any change of a preference or any
relative or other right given to any class or series of outstanding shares, then
it must be approved by the holders of a majority of each class or series
affected, excluding those shares as to which any interested stockholder
exercises voting rights. A special meeting of stockholders must be held by the
corporation to approve an Acquisition of a Controlling Interest within 50 days
after a request for such meeting is submitted by the person seeking to acquire
control. If the Control Shares are accorded full voting rights and the acquiring
person has acquired Control Shares with a majority or more of the voting power
of the corporation, all stockholders who have not voted in favor of granting
full voting rights to the Control Shares have dissenters' rights. The NRS
further provides that a corporation may opt out of the Acquisition of a
Controlling Interest protections by expressly specifying in its articles of
incorporation or bylaws that these provisions do not apply (which provision must
be in effect on the tenth day following the acquisition). iMALL has amended its
bylaws to provide that the foregoing protections do not apply to it.

     Section 203 of the DGCL prohibits a Delaware corporation from engaging in a
"business combination" with an "interested stockholder" for three years
following the date that the person becomes an interested stockholder. With
certain exceptions, an interested stockholder is a person or group who or which
owns 15% or more of the corporation's outstanding voting stock, including any
rights to acquire stock under an option, warrant, agreement, arrangement or
understanding, or upon the exercise of conversion or exchange rights, and stock
with respect to which the person has voting rights only, or is an affiliate or
associate of the corporation and was the owner of 15% or more of the
corporation's voting stock at any time within the previous three years. For
purposes of Section 203, the term "business combination" is defined broadly to
include:

     - mergers with or caused by the interested stockholder;

     - sales or other dispositions to the interested stockholder, except
       proportionately with the corporation's other stockholders, of assets of
       the corporation or a subsidiary

                                       83
<PAGE>   92

       equal to 10% or more of the aggregate market value of the corporation's
       consolidated assets or its outstanding stock;

     - the issuance or transfer by the corporation or a subsidiary of stock of
       the corporation or the subsidiary to the interested stockholder, except
       for transfers in a conversion or exchange or a pro rata distribution or
       certain other transactions, none of which increase the interested
       stockholder's proportionate ownership of any class or series of the
       corporation's or the subsidiary's stock; or

     - receipt by the interested stockholder, except proportionately as a
       stockholder, directly or indirectly, of any loans, advances, guarantees,
       pledges or other financial benefits provided by or through the
       corporation or a subsidiary.

     The three-year moratorium imposed on business combinations by Section 203
does not apply if:

     - prior to the date on which the person becomes an interested stockholder
       the board of directors approves either the business combination or the
       transaction which resulted in the person becoming an interested
       stockholder;

     - the interested stockholder owns 85% of the corporation's voting stock
       upon consummation of the transaction which made him an interested
       stockholder, excluding from the 85% calculation shares owned by directors
       who are also officers of the target corporation and shares held by
       employee stock plans which do not permit employees to decide
       confidentially whether to accept a tender or exchange offer; or

     - on or after the date the person becomes an interested stockholder, the
       board approves the business combination and it is also approved at a
       stockholder meeting by 66 2/3% of the voting stock not owned by the
       interested stockholder.

     Section 203 only applies to Delaware corporations which have a class of
voting stock that is listed on a national securities exchange are quoted on an
interdealer quotation system such as The Nasdaq National Market or are held of
record by more than 2,000 stockholders. A Delaware corporation may elect not to
be governed by Section 203 by a provision in its original certificate of
incorporation or an amendment to the certificate or to the bylaws, which
amendment must be approved by majority stockholder vote and may not be further
amended by the board of directors. Excite@Home has elected not to be governed by
Section 203, and these provisions do not apply to it. However, Excite@Home could
choose to amend its certificate of incorporation in the future and elect to be
governed by Section 203.

INSPECTION OF STOCKHOLDERS' LIST

     The DGCL allows any stockholder to inspect the stockholders' list for a
purpose reasonably related to that person's interest as a stockholder, upon
written demand under oath stating the purpose of the request. The NRS allows any
person who has been a stockholder for at least six months or who holds an
aggregate of 5% or more of the corporation's shares to inspect the stockholders'
list. Both the Excite@Home certificate of incorporation and the iMALL bylaws
allow any stockholder to inspect the stockholder list at least 10 days prior to
annual meeting of stockholders.

                  ADDITIONAL MATTER BEING SUBMITTED TO A VOTE
                             OF IMALL STOCKHOLDERS

THE PROPOSAL TO AMEND IMALL'S ARTICLES OF INCORPORATION

     Section C of Article VI of iMALL's articles of incorporation presently
requires approval by the stockholders of iMALL entitled to exercise two-thirds
of the voting power of the corporation for the sale, conveyance, transfer,
exchange or other disposition of all or substantially all of the property of
iMALL. Although the language in this section of the articles of incorporation
does not specifically include a merger, and Nevada law clearly distinguishes
between a merger and the sale, lease or exchange of assets and property as well
as the stockholder vote needed to approve each type of transaction, if the
merger were determined to fall within the meaning of this section, a vote of
two-thirds of the stockholders would be necessary to approve the merger
agreement (rather than the majority vote generally required by Nevada law).

     To eliminate any doubt as to the applicability of this voting requirement
to the approval of the merger agreement and the merger, on July 11, 1999, the
iMALL board unanimously approved and resolved to recommend to the stockholders
of iMALL for approval an amendment to the articles of incorporation deleting
this provision in its entirety from the articles of incorporation. If such an
amendment is approved by the stockholders, pursuant to the applicable Nevada
statute, iMALL may thereafter sell, lease, or exchange all or substantially all
of its property and assets, including its good will and its corporate
franchises, when and as authorized by the affirmative vote of the stockholders
of iMALL entitled to exercise at least a majority of the voting power of the
corporation. The full text of the proposed amendment to the articles of
incorporation is attached as Annex D to this prospectus/proxy statement.

     The affirmative vote of a majority of the voting power of the shares of
iMALL common stock issued and outstanding on the record date will be required to
approve the amendment to the articles of incorporation.

     IMALL'S BOARD UNANIMOUSLY RECOMMENDS A VOTE "FOR" APPROVAL OF THE AMENDMENT
TO THE ARTICLES OF INCORPORATION. THE UNANIMOUS RECOMMENDATION OF IMALL'S BOARD
DID NOT INCLUDE THE DIRECTOR DESIGNATED TO IMALL'S BOARD BY FIRST DATA, WHO
APPROPRIATELY ABSTAINED FROM VOTING ON THE AMENDMENT TO THE AMENDMENT OF THE
ARTICLES OF INCORPORATION BECAUSE OF AN ACTUAL OR POTENTIAL CONFLICT OF
INTEREST.

                             STOCKHOLDER PROPOSALS

     Under Rule 14a-8 of the Exchange Act, iMALL stockholders may present proper
proposals for inclusion in iMALL's proxy statement and for consideration at the
next annual meeting of its stockholders by submitting such proposals to iMALL in
a timely manner. In the event that the merger has not been completed prior to
the annual meeting, in order to be so included for the 1999 annual meeting,
stockholder proposals must have been received by iMALL no later than August 18,
1999, and must have otherwise complied with the requirements of Rule 14a-8. In
addition, if iMALL has not received notice on or before November 1, 1999 of any
matter a stockholder intends to propose for a vote at the 1999 annual meeting
then a proxy solicited by iMALL's board may be voted on such matter in the
discretion of the proxy holders, without discussion of the matter in the proxy
statement soliciting such proxy and without such matter appearing as a separate
matter on the proxy card.

Corporation shall be the officers of Merger Sub immediately prior to the
Effective Time, until their respective successors are duly appointed.

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

           (a) Conversion of Company Common Stock. Each share of common stock,
par value $0.008 per share, of Company ("COMPANY COMMON STOCK") issued and
outstanding immediately prior to the Effective Time, other than any shares of
Company Common Stock to be canceled pursuant to Section 1.6(b), will be canceled
and extinguished and automatically converted (subject to Sections 1.6(d) and
(e)) into the right to receive 0.46 (the "EXCHANGE RATIO") of a share of Series
A Common Stock, par value $0.01 per share, of Parent ("PARENT COMMON STOCK"). As
of the Effective Time, all such shares of Company Common Stock shall no longer
be outstanding and shall automatically be canceled and retired and shall cease
to exist, and each holder of a certificate representing any such shares of
Company Common Stock shall cease to have any rights with respect thereto, except
the right to receive upon the surrender of such certificates, certificates
representing the shares of Parent Common Stock, and cash in lieu of fractional
shares of Parent Common Stock to the extent provided in Section 1.7(e).

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

           (c) Capital Stock of Merger Sub. Each share of common stock, no par
value, of Merger Sub issued and outstanding immediately prior to the Effective
Time shall be converted into one validly issued, fully paid and nonassessable
share of common stock, no par value, of the Surviving Corporation. Each
certificate evidencing ownership of shares of the common stock of Merger Sub
shall evidence ownership of such shares of capital stock of the Surviving
Corporation.

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

           (e) Fractional Shares. No fraction of a share of Parent Common Stock
will be issued by virtue of the Merger, but in lieu thereof each holder of
shares of Company Common Stock who would otherwise be entitled to a fraction of
a share of Parent Common Stock (after aggregating all fractional shares of
Parent Common Stock that otherwise would be received by such holder) shall
receive from Parent an amount of cash (rounded to the nearest whole cent) equal
to the product of (i) such fraction, multiplied by (ii) the average closing sale
price of one share of Parent Common Stock for the ten most recent days that
Parent Common Stock has traded ending with and including the trading day
immediately prior to the Effective Time, as reported on the Nasdaq Stock Market.

           (f) Stock Options; Warrants. At the Effective Time, all options to
purchase Company Common Stock then outstanding under the Company's 1997 Stock

                                       A-3
<PAGE>   105

assumed by Parent in accordance with Section 5.8 of this Agreement. At the
Effective Time, all Company Warrants (as defined in Section 2.2) then
outstanding shall be assumed by Parent in accordance with Section 5.8 of this
Agreement.

     1.7   Surrender of Certificates.

           (a) Exchange Agent. Parent shall select a bank or trust company
acceptable to Company to act as the exchange agent (the "EXCHANGE AGENT") in the
Merger.

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

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

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

                                       A-4
<PAGE>   106

other distributions with a record date after the Effective Time payable with
respect to such whole shares of Parent Common Stock.

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

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

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

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

     1.10   Restricted Stock. If any shares of the Company Common Stock that are
outstanding immediately prior to the Effective Time are unvested or are subject
to a repurchase option, risk of forfeiture or other condition providing that
such shares ("COMPANY RESTRICTED STOCK") may be forfeited or repurchased by the
Company upon any termination of the stockholders' employment, directorship or
other relationship with the Company (and/or any affiliate of the Company) under
the terms of any restricted stock purchase agreement or other agreement with the
Company that does not by its terms provide that such repurchase option, risk of
forfeiture or other condition lapses upon consummation of the Merger, then the
shares of Parent Common Stock issued upon the conversion of such shares of
Company Common Stock in the Merger will continue to be unvested and subject to
the same

                                       A-5
<PAGE>   107

repurchase options, risks of forfeiture or other conditions following the
Effective Time, and the certificates representing such shares of Parent Stock
may accordingly be marked with appropriate legends noting such repurchase
options, risks of forfeiture or other conditions. The Company shall take all
actions that may be necessary to ensure that, from and after the Effective Time,
Parent is entitled to exercise any such repurchase option or other right set
forth in any such restricted stock purchase agreement or other agreement. A
listing of the holders of Company Restricted Stock, together with the number of
shares of Company Restricted Stock held by each, is set forth on Part 1.10 of
the Company Letter.

     1.11    Tax and Accounting Consequences.

           (a) It is intended by the parties hereto that the Merger shall
constitute a reorganization within the meaning of Section 368(a) of the Code.

           (b) It is intended by the parties hereto that the Merger shall
qualify for accounting treatment as a purchase.

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

5.2 and the filing of the Articles of Merger pursuant to Nevada Law.
Notwithstanding Company's agreement in Section 5.16 to seek the approval of

Company in accordance with its terms, except as enforceability may be limited by
bankruptcy and other similar laws affecting the rights of creditors generally
and general principles of equity. The execution and delivery of this Agreement
by Company does not, and the performance of this Agreement by Company will not,
(i) conflict with or violate the Articles of Incorporation or Bylaws of Company
or the equivalent organizational documents of any of its subsidiaries, (ii)
subject to obtaining the approval of this Agreement and the Merger by Company's
stockholders as contemplated by Section 5.2 and compliance with the requirements

subsidiaries or by which Company or any of its subsidiaries or any of their
respective properties is bound or affected, or (iii) result in any material
breach of or constitute a material default (or an event that with notice or
lapse of time or both would become a material default) under, or impair
Company's rights or alter the rights or obligations of any third party under, or
give to others any rights of termination, amendment, acceleration or
cancellation of, or result in the creation of a material Encumbrance on any of
the material properties or assets of Company or any of its subsidiaries pursuant
to, any note, bond, mortgage, indenture, contract, agreement, lease, license,
permit, franchise, concession, or other instrument or obligation to which
Company or any of its subsidiaries is a party or by which Company or any of its
subsidiaries or its or any of their respective assets are bound or affected.
Part 2.4 of the Company Letter list all consents, waivers and approvals under
any of Company's or any of its subsidiaries' agreements, contracts, licenses or
leases required to be obtained in connection with the consummation of the
transactions contemplated hereby, which, if individually or in

                                       A-9
<PAGE>   111

the aggregate not obtained, would result in a material loss of benefits to
Company or any of its subsidiaries, Parent or the Surviving Corporation.

           (b) No consent, approval, order or authorization of, or registration,
declaration or filing with any court, administrative agency or commission or
other governmental authority or instrumentality, foreign or domestic

declarations and filings as may be required under applicable federal, foreign
and state securities (or related) laws and the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended (the "HSR ACT"), and the securities or
antitrust laws of any foreign country, and (iv) such other consents,
authorizations, filings, approvals and registrations which if not obtained or
made would not be material to the Company or Parent or have a material adverse
effect on the ability of the parties hereto to consummate the Merger.

     2.5    SEC Filings; Company Financial Statements.

           (a) Except as disclosed in Part 2.5(a) of the Company Letter, Company

light of the circumstances under which they were made, not misleading, except to
the extent corrected prior to the date of this Agreement by a subsequently filed

10-Q, 8-K or any successor form under the Exchange Act) and (iii) fairly
presented in all material respects the consolidated financial position of
Company and its subsidiaries as at the respective dates thereof and the

subsidiaries, before any court, governmental department, commission, agency,
instrumentality or authority, or any arbitrator that seeks to restrain or enjoin
the consummation of the transactions contemplated by this Agreement or which
could reasonably be expected, either singularly or in the aggregate with all
such claims, actions or proceedings, to be material to Company or, following the
Merger, to the Surviving Corporation, or have a material adverse effect on the
ability of the parties hereto to consummate the Merger. Except as disclosed in

expected to, cause or provide a bona fide basis for a director or executive

is threatened or reasonably anticipated, and in the event of such Government
Audit, to the knowledge of the Company no basis exists for a finding of
noncompliance with any material provision of any government contract or a refund
of any amounts paid or owed by any Governmental Entity pursuant to such

           (b) No consent, approval, order or authorization of, or registration,

laws of any foreign country, and (iv) such other consents, authorizations,
filings, approvals and registrations which if not obtained or made would not be

of the parties hereto to consummate the Merger.

     3.4    SEC Filings; Parent Financial Statements.

           (a) Parent has filed all forms, reports and documents required to be
filed by Parent with the SEC since January 1, 1997, and has made available to
Company such forms, reports and documents in the form filed with the SEC. All
such required forms, reports and documents (including those that Parent may file
subsequent to the date hereof) are referred to herein as the "PARENT SEC
REPORTS." As of their respective dates, the Parent SEC Reports (i) were prepared
in accordance with the requirements of the Securities Act or the Exchange Act,
as the case may be, and the rules and regulations of the SEC thereunder
applicable to such Parent SEC Reports, and (ii) did not at the time they were
filed (or if amended or superseded by a filing prior to the date of this
Agreement, then on the date of such filing) contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading, except to the extent
corrected prior to the date of this Agreement by a subsequently filed Parent SEC
Report. All documents required to be filed as exhibits to the Parent SEC Reports
have been so filed. None of Parent's subsidiaries is required to file any forms,
reports or other documents with the SEC.

           (b) Each of the consolidated financial statements (including, in each
case, any related notes thereto) contained in the Parent SEC Reports (the
"PARENT FINANCIALS"), including any Parent SEC Reports filed after the date
hereof until the Closing, (i) complied as to form in all material respects with
the published rules and regulations of the SEC with respect thereto, (ii) was
prepared in accordance with GAAP applied on a consistent basis throughout the
periods involved (except as may be indicated in the notes thereto or, in the
case of unaudited interim financial statements, as may be permitted by the SEC
on Form 1O-Q, 8-K or any successor form under the Exchange Act) and (iii) fairly
presented in all material respects the consolidated financial position of Parent
and its subsidiaries as at the respective dates thereof and the consolidated
results of Parent's operations and cash flows for the periods indicated, except
that the unaudited interim financial statements may not contain footnotes and
were or are subject to normal and recurring year-end adjustments. The audited
balance sheet of Parent contained in Parent SEC Reports as of December 31, 1998
is hereinafter referred to as the "PARENT BALANCE SHEET." Except as disclosed in
the Parent Financials, since the date of the Parent Balance Sheet neither Parent
nor any of its subsidiaries has any liabilities required under GAAP to be set
forth on a balance sheet (absolute, accrued, contingent or otherwise) which are,
individually or in the aggregate, material to the business, results of
operations or financial condition of Parent and its subsidiaries taken as a
whole, except for liabilities incurred since the date of the Parent Balance
Sheet in the ordinary course of business consistent with past practices and
liabilities incurred in connection with this Agreement.

           (c) Parent has heretofore furnished to Company a complete and correct
copy of any amendments or modifications, which have not yet been filed with the
SEC but which are required to be filed, to agreements, documents or other
instruments which previously had been filed by Parent with the SEC pursuant to
the Securities Act or the Exchange Act.

     3.5    Absence of Changes. Since the date of the Parent Balance Sheet there
has not been: (i) any Material Adverse Effect with respect to Parent, (ii) any
declaration, setting

                                      A-28

aside or payment of any dividend on, or other distribution (whether in cash,
stock or property) in respect of, any of Parent's or any of its subsidiaries'
capital stock, or any purchase, redemption or other acquisition by Parent of any
of Parent's capital stock or any other securities of Parent or its subsidiaries
or any options, warrants, calls or rights to acquire any such shares or other
securities except for repurchases from employees following their termination
pursuant to the terms of their pre-existing stock option or purchase agreements,
(iii) other than a two-for-one stock split of Parent's common stock on June 16,
1999, any split, combination or reclassification of any of Parent's or any of
its subsidiaries' capital stock, (iv) any material change by Parent in its
accounting methods, principles or practices, except as required by concurrent
changes in GAAP, or (v) any material revaluation by Parent of any of its assets,
including, without limitation, writing off notes or accounts receivable other
than in the ordinary course of business.

     3.6    Litigation. There are no claims, suits, actions or proceedings
pending or, to the knowledge of Parent, threatened against, relating to or
affecting Parent or any of its subsidiaries, before any court, governmental
department, commission, agency, instrumentality or authority, or any arbitrator
that seeks to restrain or enjoin the consummation of the transactions
contemplated by this Agreement or which could reasonably be expected, either
singularly or in the aggregate with all such claims, actions or proceedings, to
be material to Parent or have a material adverse effect on the ability of the
parties hereto to consummate the Merger.

     3.7    Disclosure. None of the information supplied by Parent for inclusion
in the Registration Statement will, at the time the Registration Statement is
filed with the SEC and at the time it becomes effective under the Securities Act
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they are made, not
misleading, except that no representation or warranty is made by Parent with
respect to statements made or incorporated by reference therein about Company
supplied by Company for inclusion or incorporation by reference in the
Registration Statement. None of the information supplied by Parent for inclusion
in the Proxy Statement/Prospectus will, at the time the Proxy
Statement/Prospectus is mailed to Company's stockholders, at the time of the
Company Stockholders' Meeting or as of the Effective Time, contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the circumstances under which they are made, not misleading, or omit to state
any material fact necessary to correct any statement in any earlier
communication with respect to the solicitation of proxies for the Company
Stockholders' Meeting which has become misleading, except that no representation
or warranty is made by Parent with respect to statements made or incorporated by
reference therein about Company supplied by Company for inclusion or
incorporation by reference in the Proxy Statement/Prospectus. The Registration
Statement will comply as to form in all material respects with the provisions of
the Securities Act and the rules and regulations thereunder.

     3.8    Board Approval. The Board of Directors of Parent has approved this
Agreement, the Company Voting Agreements, the Merger and the other transactions
contemplated by this Agreement.

Merger and the transactions contemplated by this Agreement (the "OTHER
FILINGS"). Company and Parent each shall promptly supply the other with any
information which may be required in order to effectuate any filings pursuant to
this Section 5.1. Each of Company and Parent will notify the other promptly upon
the receipt of any comments from the SEC or its staff or any other government

<PAGE>   134

for filing with the SEC or other regulatory authorities under this Section 5.1
to comply in all material respects with all applicable requirements of law and
the rules and regulations promulgated thereunder. Whenever any event occurs
which is required to be set forth in an amendment or supplement to the
Prospectus/Proxy Statement, the Registration Statement or any Antitrust Filing

Stock or imposing or seeking to impose any limitation on the ability of Parent
or any of its subsidiaries or affiliates to conduct their business or own such
assets or to acquire, hold or exercise full rights of ownership of the shares of
Company Common Stock.

     5.2   Meeting of Company Stockholders.

           (a) Company will take all action necessary in accordance with the
Nevada Law and its Articles of Incorporation and Bylaws to call, notice, convene
and hold the Company Stockholders' Meeting to be held as promptly as
practicable, and in any event (to the extent permissible under applicable law)
within 45 days after the declaration of effectiveness of the Registration
Statement, for the purpose of voting upon approval of this Agreement, the Merger
and the Articles Amendment. Subject to Section 5.2(c), Company will solicit from
its stockholders proxies in favor of the approval of this Agreement, the Merger
and the Articles Amendment, and will use its commercially reasonable efforts to
take all other action necessary or advisable to secure the vote or consent of
its stockholders required by the rules of Nasdaq or Nevada Law to obtain such
approvals. Notwithstanding anything to the contrary contained in this Agreement,
Company may adjourn or postpone the Company Stockholders' Meeting to the extent
necessary to ensure that any necessary supplement or amendment to the
Prospectus/Proxy Statement is provided to Company's stockholders in advance of a
vote on this Agreement, the Merger and the Articles Amendment or, if as of the
time for which Company Stockholders' Meeting is originally scheduled (as set
forth in the Prospectus/Proxy Statement) there are insufficient shares of
Company Common Stock represented (either in person or by proxy) to constitute a
quorum necessary to conduct the business of the Company's Stockholders' Meeting.
Company shall ensure that the Company Stockholders' Meeting is called, noticed,
convened, held and conducted prior to and separate from any meeting of Company's
stockholders at which any Acquisition Proposal or Acquisition Transaction is
considered or voted upon. Company will use its commercially reasonable efforts
to ensure that all proxies solicited by Company in connection with the Company
Stockholders' Meeting are solicited in compliance with the Nevada Law, its
Articles of Incorporation and Bylaws, the rules of Nasdaq and all other
applicable legal requirements. Company's obligation to call, give notice of,
convene, hold and conduct the Company Stockholders' Meeting in accordance with
this Section 5.2(a) shall not be limited to or otherwise affected by the
commencement, disclosure, announcement or submission to Company of any
Acquisition Proposal (as defined in Section 5.4) (including a Superior Offer (as
defined in Section 5.2(c)), or by any withdrawal, amendment or modification of
the recommendation of the Board of Directors of Company to Company's
stockholders to approve this Agreement and the Merger.

                                      A-33
<PAGE>   135

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

           (c) Nothing in this Agreement shall prevent the Board of Directors of
Company from withholding, withdrawing, amending or modifying its unanimous
recommendation in favor of the Merger if (i) a Superior Offer is made to the
Company and is not withdrawn, (ii) Company shall have provided written notice to
Parent (a "NOTICE OF SUPERIOR OFFER") advising Parent that Company has received
a Superior Offer, specifying all of the material terms and conditions of such
Superior Offer and identifying the person or entity making such Superior Offer,
(iii) Parent shall not have, within five business days of Parent's receipt of
the Notice of Superior Offer, made an offer that the Company Board by a majority
vote determines in its good faith judgment (after consultation with its
financial adviser) to be at least as favorable to the Company's stockholders as
such Superior Offer (it being agreed that the Board of Directors of Company
shall convene a meeting to consider any such offer by Parent promptly following
the receipt thereof), (iv) the Board of Directors of Company concludes in good
faith, after consultation with its outside counsel, that, in light of such
Superior Offer, the withholding, withdrawal, amendment or modification of such
recommendation is required in order for the Board of Directors of Company to
comply with its fiduciary obligations to the Company's stockholders under
applicable law and (v) the Company shall not have violated any of the
restrictions set forth in Section 5.4 or this Section 5.2. The Company shall
provide Parent with at least three business days prior notice (or such lesser
prior notice as provided to the members of the Company's Board of Directors but
in no event less than twenty-four hours) of any meeting of the Company's Board
of Directors at which the Company's Board of Directors is reasonably expected to
consider any Acquisition Proposal (as defined in Section 5.4) to determine
whether such Acquisition Proposal is a Superior Offer. Subject to applicable
laws, nothing contained in this Section 5.2 shall limit the Company's obligation
to hold and convene the Company Stockholders' Meeting (regardless of whether the
unanimous recommendation of the Board of Directors of the Company shall have
been withdrawn, amended or modified). For purposes of this Agreement "SUPERIOR
OFFER" shall mean an unsolicited, bona fide written offer made by a third party
to consummate any of the following transactions: (i) a merger or consolidation
involving Company pursuant to which the stockholders of Company immediately
preceding such transaction hold less than 50% of the equity interest in the
surviving or resulting entity of such transaction or (ii) the acquisition by any
person or group (including by way of a tender offer or an exchange offer or

                                      A-34
<PAGE>   136

a two step transaction involving a tender offer followed with reasonable
promptness by a cash-out merger involving Company), directly or indirectly, of
ownership of 100% of the then outstanding shares of capital stock of Company, on
terms that the Board of Directors of Company determines, in its reasonable
judgment (after consultation with its financial adviser) to be more favorable to
Company's stockholders than the terms of the Merger; provided, however, that any
such offer shall not be deemed to be a "Superior Offer" if any financing
required to consummate the transaction contemplated by such offer is not
committed and is not likely in the reasonable judgment of the Board of Directors
of Company to be obtained by such third party on a timely basis.

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

     5.3   Confidentiality; Access to Information.

           (a) The parties acknowledge that Company and Parent have previously
executed a Confidentiality Agreement (as defined in the Company Letter), which
Confidentiality Agreement will continue in full force and effect in accordance
with its terms.

           (b) Access to Information. Company will afford Parent and its
accountants, counsel and other representatives reasonable access during normal
business hours to the properties, books, records and personnel of Company during
the period prior to the Effective Time to obtain all information concerning the
business, including the status of product development efforts, properties,
results of operations and personnel of Company, as Parent may reasonably
request. No information or knowledge obtained by Parent in any investigation
pursuant to this Section 5.3 will affect or be deemed to modify any
representation or warranty contained herein or the conditions to the obligations
of the parties to consummate the Merger.

     5.4   No Solicitation.

           (a) From and after the date of this Agreement until the Effective
Time or termination of this Agreement pursuant to Article VII, Company and its
subsidiaries will not, nor will they authorize or permit any of their respective
officers, directors, affiliates or employees or any investment banker, attorney
or other advisor or representative retained by any of them to, directly or
indirectly: (i) solicit, initiate, encourage or induce the making, submission or
announcement of any Acquisition Proposal (as hereinafter defined); (ii)
participate in any discussions or negotiations regarding, or furnish to any
person any non-public information with respect to, or take any other action to
facilitate any inquiries or the making of any proposal that constitutes or may
reasonably be expected to lead to, any Acquisition Proposal; (iii) engage in
discussions with any person with respect to any Acquisition Proposal, except as
to the existence of these provisions; (iv) except as permitted by Section
5.2(c), approve, endorse or recommend any Acquisition Proposal; or (v) enter
into any letter of intent or similar document or any contract, agreement,
agreement in principle or commitment contemplating or otherwise relating to any
Acquisition Transaction; provided, however, that prior to the approval of this
Agreement and the Merger at the Company Stockholders' Meeting, this Section
5.4(a) shall not prohibit Company from furnishing nonpublic information
regarding Company and its subsidiaries to, or entering into discussions with,
any person or group who has submitted (and not withdrawn) to Company an
unsolicited, written, bona fide Acquisition Proposal that the Board of Directors
of Company reasonably concludes (after consultation with its financial adviser)
may constitute a Superior Offer if (1) neither Company nor any representative of
Company or its subsidiaries shall have

                                      A-35

violated any of the restrictions set forth in this Section 5.4, (2) the Board of
Directors of Company concludes in good faith, after consultation with its
outside legal counsel, that such action is required in order for the Board of
Directors of Company to comply with its fiduciary obligations to Company's
stockholders under applicable law, (3) prior to furnishing any such nonpublic
information to, or entering into any such discussions with, such person or
group, Company gives Parent written notice of the identity of such person or
group and all of the material terms and conditions of such Acquisition Proposal
and of Company's intention to furnish nonpublic information to, or enter into
discussions with, such person or group, and Company receives from such person or
group an executed confidentiality agreement containing terms at least as
restrictive with regard to Company's confidential information as the
Confidentiality Agreement, (4) Company gives Parent at least three business days
advance notice of its intent to furnish such nonpublic information or enter into
such discussions, and (5) contemporaneously with furnishing any such nonpublic
information to such person or group, Company furnishes such nonpublic

previously furnished by the Company to Parent). Company and its subsidiaries
will immediately cease any and all existing activities, discussions or
negotiations with any parties conducted heretofore with respect to any
Acquisition Proposal. Without limiting the foregoing, it is understood that any
violation of the restrictions set forth in the preceding two sentences by any
officer, director or employee of Company or any of its subsidiaries or any
investment banker, attorney or other advisor or representative of Company or any
of its subsidiaries shall be deemed to be a breach of this Section 5.4 by
Company.

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

           (b) In addition to the obligations of Company set forth in paragraph
(a) of this Section 5.4, Company as promptly as practicable shall advise Parent
orally and in writing of any request for non-public information or any other
inquiry which Company reasonably believes could lead to an Acquisition Proposal
or of any Acquisition Proposal, the material terms and conditions of such
request, inquiry or Acquisition Proposal, and the identity of the person or
group making any such request, inquiry or Acquisition Proposal. Company will
keep Parent informed as promptly as practicable in all material respects of the
status and details (including material amendments or proposed amendments) of any
such request, inquiry or Acquisition Proposal.

     5.5     Public Disclosure. Parent and Company will consult with each other,
and to the extent practicable, agree, before issuing any press release or
otherwise making any public

statement with respect to the Merger, this Agreement or an Acquisition Proposal
and will not issue any such press release or make any such public statement
prior to such consultation, except as may be required by law or any listing
agreement with a national securities exchange or Nasdaq. The parties have agreed
to the text of the joint press release announcing the signing of this Agreement.

     5.6     Reasonable Efforts; Notification.

           (a) Upon the terms and subject to the conditions set forth in this
Agreement, each of the parties agrees to use all reasonable efforts to take, or
cause to be taken, all actions, and to do, or cause to be done, and to assist
and cooperate with the other parties in doing, all things necessary, proper or
advisable to consummate and make effective in an expeditious manner, the Merger
and the other transactions contemplated by this Agreement, including using
reasonable efforts to accomplish the following: (i) the taking of all reasonable
acts necessary to cause the conditions precedent set forth in Article VI to be
satisfied, (ii) the obtaining of all necessary actions or nonactions, waivers,
consents, approvals, orders and authorizations from Governmental Entities and
the making of all necessary registrations, declarations and filings (including
registrations, declarations and filings with Governmental Entities, if any) and
the taking of all reasonable steps as may be necessary to avoid any suit, claim,
action, investigation or proceeding by any Governmental Entity, (iii) the
obtaining of all necessary consents, approvals or waivers from third parties,
(iv) the defending of any suits, claims, actions, investigations or proceedings,
whether judicial or administrative, challenging this Agreement or the
consummation of the transactions contemplated hereby, including seeking to have
any stay or temporary restraining order entered by any court or other
Governmental Entity vacated or reversed and (v) the execution or delivery of any
additional instruments necessary to consummate the transactions contemplated by,
and to fully carry out the purposes of, this Agreement. Notwithstanding anything
in this Agreement to the contrary, neither Parent nor any of its affiliates
shall be under any obligation to make proposals, execute or carry out agreements
or submit to orders providing for the sale or other disposition or holding
separate (through the establishment of a trust or otherwise) of any assets or
categories of assets of Parent, any of its affiliates or Company or the holding
separate of the shares of Company Common Stock or imposing or seeking to impose
any limitation on the ability of Parent or any of its subsidiaries or affiliates
to conduct their business or own such assets or to acquire, hold or exercise
full rights of ownership of the shares of Company Common Stock.

           (b) Each of Company and Parent will give prompt notice to the other
of (i) any notice or other communication from any person alleging that the
consent of such person is or may be required in connection with the Merger, (ii)
any notice or other communication from any Governmental Entity in connection
with the Merger, (iii) any litigation relating to, involving or otherwise
affecting Company, Parent or their respective subsidiaries that relates to the
consummation of the Merger. Company shall give prompt notice to Parent of any
representation or warranty made by it contained in this Agreement becoming
untrue or inaccurate, or any failure of Company to comply with or satisfy in any
material respect any covenant, condition or agreement to be complied with or
satisfied by it under this Agreement, in each case, such that the conditions set
forth in Section 6.3 would not be satisfied, provided, however, that no such
notification shall affect the representations, warranties, covenants or
agreements of the parties or the conditions to the obligations of the parties
under this Agreement. Parent shall give prompt notice to Company of any
representation or warranty made by it or Merger Sub contained in this Agreement
becoming untrue or inaccurate, or any failure of Parent or Merger Sub to comply
with or satisfy in any material respect any

                                      A-37
<PAGE>   139

covenant, condition or agreement to be complied with or satisfied by it under
this Agreement, in each case, such that the conditions set forth in Section 6.2
would not be satisfied, provided, however, that no such notification shall
affect the representations, warranties, covenants or agreements of the parties
or the conditions to the obligations of the parties under this Agreement.

     5.7    Third Party Consents. As soon as practicable following the date
hereof, Parent and Company will each use its commercially reasonable efforts to
obtain any consents, waivers and approvals under any of its or its subsidiaries'
respective agreements, contracts, licenses or leases required to be obtained in
connection with the consummation of the transactions contemplated hereby.

     5.8    Stock Options.

           (a) At the Effective Time, each outstanding Company Option, whether
or not then exercisable, will be assumed by Parent. Each Company Option so
assumed by Parent under this Agreement will continue to have, and be subject to,
the same terms and conditions set forth in the applicable Company Stock Option
Plan immediately prior to the Effective Time (including any repurchase rights or
vesting provisions), except that (i) each Company Stock Option will be
exercisable (or will become exercisable in accordance with its terms) for that
number of whole shares of Parent Common Stock equal to the product of the number
of shares of Company Common Stock that were issuable upon exercise of such
Company Option immediately prior to the Effective Time multiplied by the
Exchange Ratio, rounded down to the nearest whole number of shares of Parent
Common Stock and (ii) the per share exercise price for the shares of Parent
Common Stock issuable upon exercise of such assumed Company Stock Option will be
equal to the quotient determined by dividing the exercise price per share of
Company Common Stock at which such Company Option was exercisable immediately
prior to the Effective Time by the Exchange Ratio, rounded up to the nearest
whole cent. Continuous employment with Company or its subsidiaries shall be
credited to the optionee for purposes of determining the vesting of all assumed
Company Options after the Effective Time.

           (b) It is intended that Company Options assumed by Parent shall
qualify following the Effective Time as incentive stock options as defined in
Section 422 of the Code to the extent such Company Options qualified as
incentive stock options immediately prior to the Effective Time and the
provisions of this Section 5.8 shall be applied consistent with such intent.

           (c) At the Effective Time, each Company Warrant, whether or not then
exercisable, will be assumed by Parent. Each Company Warrant so assumed by
Parent under this Agreement will continue to have, and be subject to, the same
terms and conditions set forth in the applicable Company Warrant immediately
prior to the Effective Time (including any vesting provisions), except that (i)
each Company Warrant will be exercisable (or will become exercisable in
accordance with its terms) for that number of whole shares of Parent Common
Stock equal to the product of the number of shares of Company Common Stock that
were issuable upon exercise of such Company Warrant immediately prior to the
Effective Time multiplied by the Exchange Ratio, rounded down to the nearest
whole number of shares of Parent Common Stock and (ii) the per share exercise
price for the shares of Parent Common Stock issuable upon exercise of such
assumed Company Warrant will be equal to the quotient determined by dividing the
exercise price per share of Company Common Stock at which such Company Warrant
was exercisable immediately prior to the Effective Time by the Exchange Ratio,
rounded up to the nearest whole cent.

<PAGE>   140

     5.9    Registrations. Parent agrees to file a registration statement on
Form S-8 for the shares of Parent Common Stock issuable with respect to assumed
Company Options as soon as is reasonably practicable after the Effective Time
and shall maintain the effectiveness of such registration statement thereafter
for so long as any of such options or other rights remain outstanding. Parent
agrees to file at its expense a registration statement on Form S-3 for the
shares of Parent Common Stock issuable with respect to Company Warrants assumed
by Parent hereunder as soon as is reasonably practicable after the Effective
Time and shall maintain the effectiveness of such registration statement
thereafter for a period ending on the one year anniversary of the Effective
Time. The registration rights granted hereunder shall be subject to customary
blackout periods imposed by Parent in its discretion.

     5.10    Indemnification. From and after the Effective Time, Parent will
cause the Surviving Corporation to fulfill and honor in all respects the
obligations of Company pursuant to any indemnification agreements between
Company and its directors and officers as of the Effective Time (the
"INDEMNIFIED PARTIES") and any indemnification provisions under Company's
Articles of Incorporation or Bylaws as in effect on the date hereof. The
Articles of Incorporation and Bylaws of the Surviving Corporation will contain
provisions with respect to exculpation and indemnification that are
substantially as favorable to the Indemnified Parties as those contained in the
Articles of Incorporation and Bylaws of Company as in effect on the date hereof,
which provisions will not be amended, repealed or otherwise modified for a
period of six years from the Effective Time in any manner that would adversely
affect the rights thereunder of individuals who, immediately prior to the
Effective Time, were directors, officers, employees or agents of Company, unless
such modification is required by law. This Section 5.10 shall survive the
consummation of the Merger, is intended to benefit Company, the Surviving
Corporation and each Indemnified Party, shall be binding on all successors and
assigns of the Surviving Corporation and Parent, and shall be enforceable by the
Indemnified Parties. For a period of six years after the Effective Time, Parent
will cause the Surviving Corporation to use its commercially reasonable efforts
to maintain in effect, if available, directors' and officers' liability
insurance covering those persons who are currently covered by the Company's
directors' and officers' liability insurance policy on terms comparable to those
applicable to the current directors and officers of Company; provided, however,
that in no event will Parent or Surviving Corporation be required to expend in
excess of 150% of the annual premium currently paid by Company for such
coverage, and if the annual premium for such coverage exceeds 150% of such
existing annual premium, Parent or Surviving Corporation shall maintain
insurance policies which provide the maximum coverage available at an annual
premium equal to 150% of such amount.

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

     5.12    Affiliates; Restrictive Legend. Not less than five business days
prior to the Closing, Company will deliver to Parent a complete list of those
persons who may be deemed to be, in Company's reasonable judgment, affiliates of
Company within the meaning of Rule 145 promulgated under the Securities Act.
Parent will give stop transfer instructions to its transfer agent with respect
to any Parent Common Stock received pursuant to the Merger by any stockholder of
the Company who may reasonably be deemed to be an affiliate of

                                      A-39
<PAGE>   141

Company and there will be placed on the certificates representing such Parent
Common Stock, or any substitutions therefor, a legend stating in substance:

     THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A TRANSACTION TO
     WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF 1933, AS AMENDED,
     APPLIES AND MAY ONLY BE TRANSFERRED IN CONFORMITY WITH RULE 145(d) UNDER
     SUCH ACT.

     5.13    Letter of Company's Accountants. Company shall use all reasonable
efforts to cause to be delivered to Parent a letter of Arthur Andersen LLP,
dated no more than two business days before the date on which the Registration
Statement becomes effective (and reasonably satisfactory in form and substance
to Parent), that is customary in scope and substance for letters delivered by
independent public accountants in connection with registration statements
similar to the Registration Statement.

     5.14    Takeover Statutes. If any "control share acquisition", "fair
price", "moratorium" or other similar anti-takeover statute or regulation is or
may become applicable to the Merger or the other transactions contemplated by
this Agreement, each of Parent and Company and their respective Boards of
Directors shall grant such approvals and take such lawful actions as are
necessary to ensure that such transactions may be consummated as promptly as
practicable on the terms contemplated by this Agreement and otherwise act to
eliminate or minimize the effects of such statute and any regulations
promulgated thereunder on such transactions.

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

     5.16   Amendment of Company's Articles. Company agrees that at the Company
Stockholders' Meeting, in addition to seeking the approval of this Agreement and
the Merger by Company's stockholders, Company shall also seek the approval of
Company's stockholders, by the vote required under applicable law, of an
amendment of Company's Articles of Incorporation to delete in its entirety
Article VI.C. thereof (such amendment, the "ARTICLES AMENDMENT").

     5.17   Parent Warrant. At the Effective Time, Parent shall issue to First
Data a warrant in substantially the form attached hereto as Exhibit A (the
"PARENT WARRANT"). At the time of issuance, the Parent Warrant shall entitle the
holder thereof to purchase 2,300,000 shares of Parent Common Stock at an
exercise price of $36.9565 per share; provided, however, that if the Parent
Warrant had been issued on the date hereof with such terms and prior to the time
at which it is actually issued pursuant to this Section 5.17, the number of
shares of Parent Common Stock covered by the Parent Warrant, the exercise price
per share or the type of securities deliverable upon exercise of the Parent
Warrant would have been adjusted or changed pursuant to the terms of the Parent
Warrant, the Parent Warrant shall be issued with such adjustments or changes.
First Data is an intended third party beneficiary of this Section 5.17.

prohibiting Parent's ownership or operation of, or compelling Parent to dispose
of or hold separate, all or a material portion of the business or assets of

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

those representations and warranties which address matters only as of a
particular date (which representations shall have been true and correct (subject

(b), 2.3, 2.18, 2.20 and 2.21 (which representations shall be true and correct
at the applicable times in all material respects) and (B) for those
representations and warranties which address matters only as of a particular
date (which representations shall have been true and correct (subject to the
qualifications set forth in the preceding clause (A)) as of such particular

condition shall be deemed to be satisfied with respect to the agreements and
covenants required by this Agreement to be performed or complied with by Company
set forth in Sections 5.1, 5.3, 5.5, 5.6, 5.7, 5.12, 5.13, 5.15 if such

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

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

           (b) by either Company or Parent if the Merger shall not have been
consummated by March 1, 2000 for any reason; provided, however, that the right
to terminate this Agreement under this Section 7.1(b) shall not be available to
any party whose action or failure to act has been a principal cause of or
resulted in the failure of the Merger to occur on or before such date and such
action or failure to act constitutes a breach of this Agreement;

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

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

                                      A-43
<PAGE>   145

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

           (f) by Company, upon a breach of any representation, warranty,
covenant or agreement on the part of Parent set forth in this Agreement, or if
any representation or warranty of Parent shall have become untrue, in either
case such that the conditions set forth in Section 6.2(a) or Section 6.2(b)
would not be satisfied as of the time of such breach or as of the time such
representation or warranty shall have become untrue, provided that if such
inaccuracy in Parent's representations and warranties or breach by Parent is
curable by Parent through the exercise of its commercially reasonable efforts,
then Company may not terminate this Agreement under this Section 7.1(f) for 30
days after delivery of written notice from Company to Parent of such breach,
provided Parent continues to exercise commercially reasonable efforts to cure
such breach (it being understood that Company may not terminate this Agreement
pursuant to this paragraph (f) if such breach by Parent is cured during such
30-day period, or if Company shall have materially breached this Agreement); or

           (g) by Parent, upon a breach of any representation, warranty,
covenant or agreement on the part of Company set forth in this Agreement, or if
any representation or warranty of Company shall have become untrue, in either
case such that the conditions set forth in Section 6.3(a) or Section 6.3(b)
would not be satisfied as of the time of such breach or as of the time such
representation or warranty shall have become untrue, provided that if such
inaccuracy in Company's representations and warranties or breach by Company is
curable by Company through the exercise of its commercially reasonable efforts,
then Parent may not terminate this Agreement under this Section 7.1(g) for 30
days after delivery of written notice from Parent to Company of such breach,
provided Company continues to exercise commercially reasonable efforts to cure
such breach (it being understood that Parent may not terminate this Agreement
pursuant to this paragraph (g) if such breach by Company is cured during such

           (a) General. Except as set forth in this Section 7.3, all fees and

immediately available funds. In the event that (i) this Agreement is terminated
by Parent or Company, as applicable, pursuant to Section 7.1(d), (ii) following

contemplated by this Agreement, and that, without these agreements, Parent would
not enter into this Agreement; accordingly, if Company fails to pay in a timely
manner the amounts due pursuant to this Section 7.3(b),

judgment against Company for the amounts set forth in this Section 7.3(b),
Company shall pay to Parent its reasonable costs and expenses (including
reasonable attorneys' fees and expenses) in connection with such suit, together
with interest on the amounts set forth in this Section 7.3(b) at the prime rate

such extension or waiver shall be valid only if set forth in an instrument in
writing signed on behalf of such party. Delay in exercising any right under this
Agreement shall not constitute a waiver of such right.

enforceable provision that will achieve, to the extent possible, the economic,
business and other purposes of such void or unenforceable provision.

     8.7    Other Remedies; Specific Performance. Except as otherwise provided

pursuant to Section 3 below, at every meeting of the stockholders of Company

Incorporation regarding a supermajority vote requirement in certain dispositions
of assets of the Company and (iii) against approval of (a) any proposal made in
opposition to or in competition with consummation of the Merger, (b) any merger,
consolidation, sale of assets, reorganization or recapitalization with any party
other than Parent or its affiliates or (c) any liquidation or winding up of
Company.

     1.3   Irrevocable Proxy. Concurrently with the execution of this Agreement,
Stockholder agrees to deliver to Parent a proxy in the form attached hereto as

Stockholder to carry out the terms of this Agreement; and (ii) has the legal
capacity or full corporate power and authority to make, enter into and carry out
the terms of this Agreement.

     3.     Termination. This Agreement shall terminate and shall have no
further force or effect as of the first to occur of (i) such date and time as
the Merger shall become effective in accordance with the terms and provisions of
the Merger Agreement, or (ii) such date and time as the Merger Agreement shall
have been terminated pursuant to Article VII thereof.

     4.     Miscellaneous.

     4.1   Severability. If any term, provision, covenant or restriction of this

     4.2   Binding Effect and Assignment. This Agreement and all of the
provisions hereof shall be binding upon and inure to the benefit of the parties
hereto and their respective successors and permitted assigns, but, except as
otherwise specifically provided herein, neither this Agreement nor any of the

     4.4   Specific Performance; Injunctive Relief. The parties hereto
acknowledge that Parent will be irreparably harmed and that there will be no
adequate remedy at law for a violation of any of the covenants or agreements of
Stockholder set forth herein. Therefore, it is agreed that, in addition to any
other remedies that may be available to Parent upon any such violation, Parent
shall have the right to enforce such covenants and agreements by specific

                                 July 11, 1999

Board of Directors
iMALL, Inc.
233 Wilshire Boulevard
Santa Monica, CA 90401

Members of the Board:

     We understand that iMALL, Inc. (the "Company"), At Home Corporation
("Acquiror"), and Shop Nevada, Inc. (a wholly owned subsidiary of Acquiror,
"Merger Sub") are proposing to enter into the Agreement and Plan of Merger dated
as of July 12, 1999 among Acquiror, Merger Sub and the Company (the
"Agreement"), which will provide, among other things, for the merger (the
"Merger") of Merger Sub with and into the Company. Upon consummation of the
Merger, the Company will become a wholly owned subsidiary of Acquiror. Under the
terms set forth in the Agreement, at the effective time of the Merger, the
outstanding shares of common stock of the Company, par value $0.008 per share
("Company Common Stock"), other than certain shares to be cancelled pursuant to
the Agreement, will be converted into the right to receive 0.4600 (the "Exchange
Ratio") shares of the Series A common stock of Acquiror, par value $0.01 per
share ("Acquiror Common Stock"). The terms and conditions of the Merger are set
out more fully in the Agreement.

     You have asked whether, in our opinion, the Exchange Ratio is fair from a
financial point of view and as of the date hereof to the "Holders of Company
Common Stock." The "Holders of Company Common Stock" shall be defined as all
holders of Company Common Stock other than Acquiror, Merger Sub or any
affiliates of Acquiror or Merger Sub.

     For purposes of this opinion we have, among other things:

     (i)   reviewed certain publicly available financial statements and other
           business and financial information of the Company and Acquiror,
           respectively;

     (ii)  reviewed certain internal financial statements and other financial
           and operating data concerning the Company prepared by the management
           of the Company;

     (iii)  reviewed certain financial forecasts and other forward looking
            financial information prepared by the management of the Company. In
            addition, we reviewed with Acquiror certain publicly available
            estimates of research analysts relating to Acquiror;

     (iv)  held discussions with the respective managements of the Company and
           Acquiror concerning the businesses, past and current operations,
           financial condition and future prospects of both the Company and
           Acquiror, independently and combined, including discussions with the
           managements of the Company and Acquiror concerning cost savings and
           other synergies that are expected to result from the Merger, as well
           as their views regarding the strategic rationale for the Merger;

     (v)   reviewed the financial terms and conditions set forth in the
           Agreement and the agreements ancillary thereto;

                                       C-1
<PAGE>   158

     (vi)  reviewed the stock price and trading history of the Company and
           Acquiror;

     (vii)  compared the financial performance of the Company and Acquiror and
            the prices and trading activity of Company Common Stock and Acquiror
            Common Stock with that of certain other publicly traded companies we
            deemed comparable with the Company and Acquiror, respectively;

     (viii) compared the financial terms of the Merger with the financial terms,
            to the extent publicly available, of other transactions that we
            deemed relevant;

     (ix)  reviewed the pro forma impact of the Merger on Acquiror's cash
           earnings per share and revenue per share;

     (x)   participated in discussions and negotiations among representatives of
           the Company and Acquiror and their financial and legal advisors; and

     (xi)  made such other studies and inquiries, and reviewed such other data,
           as we deemed relevant.

     In our review and analysis, and in arriving at our opinion, we have assumed
and relied upon the accuracy and completeness of all of the financial and other
information provided to us (including information furnished to us orally or
otherwise discussed with us by managements of the Company and Acquiror) or
publicly available and have neither attempted to verify, nor assumed
responsibility for verifying, any of such information. We have relied upon the
assurances of managements of the Company and Acquiror that they are not aware of
any facts that would make such information inaccurate or misleading.
Furthermore, we did not obtain or make, or assume any responsibility for
obtaining or making, any independent evaluation or appraisal of the properties,
assets or liabilities (contingent or otherwise) of the Company or Acquiror, nor
were we furnished with any such evaluation or appraisal. With respect to the
financial forecasts and projections (and the assumptions and bases therefor) for
each of the Company and Acquiror that we have reviewed, upon the advice of the
managements of the Company and Acquiror, we have assumed that such forecasts and
projections have been reasonably prepared in good faith on the basis of
reasonable assumptions and reflect the best currently available estimates and
judgments as to the future financial condition and performance of the Company
and Acquiror, respectively, and we have further assumed that such projections
and forecasts will be realized in the amounts and in the time periods currently
estimated. In this regard, we note that each of the Company and Acquiror face
exposure to the Year 2000 problem. We have not undertaken any independent
analysis to evaluate the reliability or accuracy of the assumptions made by the
managements of the Company and Acquiror with respect to the potential effect
that the Year 2000 problem might have on their respective forecasts. We have
assumed that the Merger will be consummated upon the terms set forth in the
Agreement without material alteration thereof, including, among other things,
that the Merger will be accounted for as "purchase method" business combination
in accordance with U.S. generally accepted accounting principles ("GAAP"), that
the Merger will be treated as tax-free reorganization pursuant to the Internal
Revenue Code of 1986, as amended and that the First Data Corporation agreement
described in the Agreement will be executed and in full force and effect. In
addition, we have assumed that the historical financial statements of each of
the Company and Acquiror reviewed by us have been prepared and fairly presented
in accordance with U.S. GAAP consistently applied. We have relied as to all
legal matters relevant to rendering our opinion on the advice of counsel.

     This opinion is necessarily based upon market, economic and other
conditions as in effect on, and information made available to us as of, the date
hereof. It should be understood that

                                       C-2
<PAGE>   159

subsequent developments may affect the conclusion expressed in this opinion and
that we disclaim any undertaking or obligation to advise any person of any
change in any matter affecting this opinion which may come or be brought to our
attention after the date of this opinion. Our opinion is limited to the
fairness, from a financial point of view and as to the date hereof, to the
Holders of Company Common Stock of the Exchange Ratio. We do not express any
opinion as to (i) the value of any employee agreement or other arrangement
entered into in connection with the Merger, (ii) any tax or other consequences
that might result from the Merger or (iii) what the value of Acquiror Common
Stock will be when issued to the Company's stockholders pursuant to the Merger
or the price at which the shares of Acquiror Common Stock that are issued
pursuant to the Merger may be traded in the future. Our opinion does not address
the relative merits of the Merger and the other business strategies that the
Company's Board of Directors has considered or may be considering, nor does it
address the decision of the Company's Board of Directors to proceed with the
Merger.

     In connection with the preparation of our opinion, we were not authorized
to solicit, and did not solicit, third-parties regarding alternatives to the
Merger.

     We are acting as financial advisor to the Company in connection with the
Merger and will receive a fee upon the consummation of the Merger. In addition,
the Company has agreed to indemnify us for certain liabilities that may arise
out of the rendering of this opinion. In the past, we have provided certain
investment banking services to the Company. In the ordinary course of business,
we may trade in the Company's securities and Acquiror's securities for our own
account and the account of our customers and, accordingly, may at any time hold
a long or short position in the Company's securities or Acquiror's securities.

     Our opinion expressed herein is provided for the information of the Board
of Directors of the Company in connection with its evaluation of the Merger. Our
opinion is not intended to be and does not constitute a recommendation to any
stockholder of the Company as to how such stockholder should vote, or take any
other action, with respect to the Merger. This opinion may not be summarized,
described or referred to or furnished to any party except with our express prior
written consent.

     Based upon and subject to the foregoing considerations, it is our opinion
that as of the date hereof, the Exchange Ratio is fair to the Holders of Company
Common Stock from a financial point of view.

                                              Very truly yours,

ITEM 20. INDEMNIFICATION OF OFFICERS AND DIRECTORS

     As permitted by the Delaware General Corporation Law, the Registrant's
Certificate of Incorporation includes a provision that eliminates the personal
liability of its directors to the Registrant or its stockholders for monetary
damages for breach of fiduciary duty as a director, except for liability:

     - for any breach of the director's duty of loyalty to the corporation or
       its stockholders;

     - for acts or omissions not in good faith or that involve intentional
       misconduct or a knowing violation of law;

     - under Section 174 of the Delaware General Corporation Law; or

     - for any transaction from which the director derived an improper personal
       benefit.

     As permitted by Section 145 of the Delaware General Corporation Law, the
Registrant's Certificate of Incorporation further provides:

     - for mandatory indemnification, to the fullest extent permitted by
       applicable law, for any person who is or was a director or officer, or is
       or was serving at the request of the Registrant as a director, officer,
       employee or agent of another corporation or of a partnership, joint
       venture, trust, enterprise or nonprofit entity, including service with
       respect to employee benefit plans, against all liability and loss
       suffered and expenses (including attorneys' fees) reasonably incurred by
       such person;

     - that the Registrant's obligation to indemnify any person who was or is
       serving at the Registrant's request as a director, officer, employee or
       agent of another corporation, partnership, joint venture, trust,
       enterprise or nonprofit entity must be reduced by any amount such person
       may collect as indemnification from such other corporation, partnership,
       joint venture, trust, enterprise or nonprofit entity;

     - that the Registrant must advance to all indemnified parties the expenses
       (including attorney's fees) incurred in defending any proceeding provided
       that indemnified parties (if they are directors or officers) must provide
       the Registrant an undertaking to repay such advances if indemnification
       is determined to be unavailable;

     - that the rights conferred in the Certificate of Incorporation are not
       exclusive; and

     - that the Registrant may not retroactively amend the Certification of
       Incorporation provisions relating to indemnity.

     The indemnification provision in the Registrant's Certificate of
Incorporation and the Indemnification Agreements entered into between the
Registrant and each of its directors and executive officers may be sufficiently
broad to permit indemnification of the Registrant's directors and officers for
liabilities arising under the Securities Act.

     The Registrant has also obtained directors' and officers' liability
insurance.

ITEM 22. UNDERTAKINGS

     The undersigned registrant hereby undertakes:

          (a) That, for purposes of determining any liability under the
     Securities Act of 1933, each filing of the registrant's annual report
     pursuant to section 13(a) or section 15(d) of the Securities Exchange Act
     of 1934 (and, where applicable, each filing of an employee benefit plan's
     annual report pursuant to section 15(d) of the Securities Exchange Act of
     1934) that is incorporated by reference in the registration statement shall
     be deemed to be a new registration statement relating to the securities
     offered therein, and the offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.

          (b) That prior to any public reoffering of the securities registered
     hereunder through use of a prospectus which is a part of this registration
     statement, by any person or party who is deemed to be an underwriter within
     the meaning of Rule 145(c), the registrant undertakes that such reoffering
     prospectus will contain the information called for by the applicable
     registration form with respect to reofferings by persons who may be deemed
     underwriters, in addition to the information called for by the other Items
     of the applicable form.

          (c) That every prospectus (i) that is filed pursuant to paragraph (b)
     immediately preceding, or (ii) that purports to meet the requirements of
     section 10(a)(3) of the Act and is used in connection with an offering of
     securities subject to Rule 415, will be filed as a part of an amendment to
     the registration statement and will not be used until such amendment is
     effective, and that, for purposes of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.

                                      II-3
<PAGE>   165

          (d) To respond to requests for information that is incorporated by
     reference into the prospectus pursuant to Items 4, 10(b), 11, or 13 of this
     Form, within one business day of receipt of such request, and to send the
     incorporated documents by first class mail or other equally prompt means.
     This includes information contained in documents filed subsequent to the
     effective date of the registration statement through the date of responding
     to the request.

          (e) To supply by means of a post-effective amendment all information
     concerning a transaction, and the company being acquired involved therein,
     that was not the subject of and included in the registration statement when
     it became effective.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

Gentlemen/Ladies:

     At your request, we have examined the Registration Statement on Form S-4
(the "REGISTRATION STATEMENT") to be filed by you with the Securities and
Exchange Commission (the "COMMISSION") on or about September 22, 1999 in
connection with the registration under the Securities Act of 1933, as amended,
of an aggregate of 10,021,614 shares of your Series A Common Stock (the
"STOCK").

     In rendering this opinion, we have examined the following:

     (1)  your registration statement on Form 8-A filed with the Commission on
          June 13, 1997 (File No. 000-22697), together with the order of
          effectiveness issued by the Commission therefor on July 11, 1997;

     (2)  your Annual Report on Form 10-K for the year ended December 31, 1998,
          as amended;

     (3)  your Quarterly Report on Form 10-Q for the quarters ended March 31 and
          June 30, 1999;

     (4)  your Current Reports on Form 8-K filed with the Commission on January
          14, 1999, January 21, 1999, February 19, 1999, April 8, 1999 and June
          14, 1999, and your amended Current Report on Form 8-K filed with the
          Commission on February 19, 1999;

     (5)  the Registration Statement, together with the exhibits filed as a part
          thereof;

     (6)  the prospectus prepared in connection with the Registration Statement
          (the "PROSPECTUS");

     (7)  the Nasdaq National Market Notification Form for Listing of Additional
          Shares prepared in connection with the conversion of the Debentures;

     (8)  your Fifth Amended and Restated Certificate of Incorporation filed
          with the Delaware Secretary of State on May 28, 1999 and your Second
          Amended and

<PAGE>   2

September 22, 1999
Page 2


          Restated Bylaws, each of which are listed as exhibits to the
          Registration Statement;

      (9) the minutes of meetings and actions by written consent of the
          stockholders and Board of Directors that are contained in your minute
          books that are in our possession;

     (10) summary reports from you confirming the number of shares of your
          capital stock outstanding as of September 2 , 1999 and the number of
          options, warrants and any other rights to acquire shares of your
          capital stock outstanding as of September 2 , 1999; and

     (11) a Management Certificate addressed to us and dated of even date
          herewith executed by you containing certain factual and other
          representations.

     By telephone call to the offices of the Commission, we have confirmed the
continued effectiveness of your registration under the Securities Exchange Act
of 1934, as amended (the "EXCHANGE ACT"), and the timely filing by you of all
reports required to be filed by you pursuant to Rules 13, 14 and 15 promulgated
under the Exchange Act.

     In our examination of documents for purposes of this opinion, we have
assumed, and express no opinion as to, the genuineness of all signatures on
original documents, the authenticity and completeness of all documents submitted
to us as originals, the conformity to originals and completeness of all
documents submitted to us as copies, the legal capacity of all natural persons
executing the same, the lack of any undisclosed termination, modification,
waiver or amendment to any document reviewed by us and the due authorization,
execution and delivery of all documents where due authorization, execution and
delivery are prerequisites to the effectiveness thereof.

     As to matters of fact relevant to this opinion, we have relied solely upon
our examination of the documents referred to above and have assumed the current
accuracy and completeness of the information obtained from public officials and
records referred to above. We have made no independent investigation or other
attempt to verify the accuracy of any of such information or to determine the
existence or non-existence of any other factual matters; however, we are not
aware of any facts that would cause us to believe that the opinion expressed
herein is not accurate.

     We are admitted to practice law in the State of California, and we express
no opinion herein with respect to the application or effect of the laws of any
jurisdiction other than the existing laws of the United States of America and
the State of California and (without reference to case law or secondary sources)
the existing Delaware General Corporation Law.

     In connection with our opinion expressed below, we have assumed that, at or
prior to the time of the delivery of any shares of Stock, the Registration
Statement will have been declared effective under the Securities Act of 1933, as
amended, that the registration will apply to such

<PAGE>   3

September 22, 1999
Page 3


shares of Stock and will not have been modified or rescinded and that there will
not have occurred any change in law affecting the validity or enforceability of
such shares of Stock.

     Based upon the foregoing, it is our opinion that up to 10,021,614 shares of
Stock to be issued and sold by you, when issued and sold in accordance in the
manner referred to in the Prospectus and the Registration Statement, will be
validly issued, fully paid and nonassessable.

     We consent to the use of this opinion as an exhibit to the Registration
Statement and further consent to all references to us, if any, in the
Registration Statement, the Prospectus constituting a part thereof and any
amendments thereto.

     This opinion speaks only as of its date and we assume no obligation to
update this opinion should circumstances change after the date hereof. This
opinion is intended solely for the your use as an exhibit to the Registration
Statement for the purpose of the above sale of the Stock and is not to be relied
upon for any other purpose.

                                        Very truly yours,

                                        FENWICK & WEST LLP

                Re:     EXHIBIT TAX OPINION RENDERED IN CONNECTION WITH THE
                        FILING OF AN S-4 REGISTRATION STATEMENT PERTAINING TO
                        THE MERGER TRANSACTION BETWEEN AND AMONG @HOME
                        CORPORATION INC., SHOP NEVADA, INC. AND iMALL, INC.

Ladies and Gentlemen:

        We have been requested to render this opinion concerning certain matters
of U.S. federal income tax law in connection with the proposed merger (the
"MERGER") involving iMALL, Inc., a corporation organized and existing under the
laws of the State of Nevada ("TARGET") and Shop Nevada, Inc., a corporation
organized and existing under the laws of State of Nevada ("MERGER SUB"), which
is a wholly owned first tier subsidiary of @Home Corporation., a corporation
organized and existing under the laws of the State of Delaware ("PARENT"). The
Merger is further described in and is in accordance with the Securities and
Exchange Commission Form S-4 Registration Statement to be filed on or soon after
September 24, 1999, and related Exhibits thereto, (the "S-4 REGISTRATION
STATEMENT"). Our opinion has been requested solely in connection with the filing
of the S-4 Registration Statement with the Securities and Exchange Commission
with respect to the Merger and cannot be use or relied upon by any person or
entity for any other purpose.

        The Merger is structured as a statutory merger of Merger Sub with and
into the Target, with Target surviving the merger and becoming a wholly-owned
subsidiary of Parent, all pursuant to the applicable corporate laws of the State
of Nevada, the State of Delaware, and in accordance with the Agreement and Plan
of Reorganization by and among Merger Sub, Parent, and Target, dated as of July
12, 1999, and exhibits thereto (collectively, the "MERGER AGREEMENT"). Except as
otherwise indicated, capitalized terms used herein have the meanings set forth
in the Merger Agreement. All section references, unless otherwise indicated, are
to the Internal Revenue Code of 1986, as amended (the "CODE").

with the Merger. As such, and for the purpose of rendering this opinion, we have
examined and are relying upon (without any independent investigation or review
thereof) the truth and accuracy, at all relevant times, of the statements,
covenants, representations and warranties contained in the following documents
(including all schedules and exhibits thereto), among others:

        1.      The Merger Agreement;

        2.      A Tax Matters Certificate of Parent and Merger Sub dated
September 22, 1999, signed by an authorized officer of each of Parent and Merger
Sub and delivered to us from Parent and Merger Sub, and incorporated herein in
its entirety by reference, attached hereto as Exhibit A;

        3.      A Tax Matters Certificate of Target dated September 22, 1999,
signed by an authorized officer of Target and delivered to us from Target, and
incorporated herein in its entirety by reference, attached hereto as Exhibit B;
and

        4.      Such other instruments and documents related to the formation,
organization and operation of Merger Sub, Parent, or Target or the consummation
of the Merger and other transactions contemplated thereby as we have deemed
necessary or appropriate.

        In connection with rendering this opinion, we have assumed or obtained
representations and are relying thereon (without any independent investigation
or review thereof) that:

        a.      Original documents (including signatures thereto) are authentic,
documents submitted to us as copies conform to the original documents, and that
all such documents have been (or will be by the Effective Time of the Merger)
duly executed and delivered where due execution and delivery are prerequisites
to the effectiveness thereof;

        Any representation or statement made "to the best of knowledge" or
otherwise similarly qualified is correct without such qualification, and all
statements and representations, whether or not qualified, are true and will
remain true through the Effective Date, and thereafter where relevant;

        All statements, descriptions and representations contained in any of the
documents referred to herein or otherwise made to us are true and correct in all
material respects and no actions have been (or will be) taken which are
inconsistent with such representations;

        b.      All covenants contained in the Merger Agreement (including
exhibits thereto) are performed without waiver or breach of any material
provision thereof;

        The Merger will be consummated pursuant to the Merger Agreement and will
be effective under the laws of the States of Nevada and Delaware;

        No Merger Sub stockholder has guaranteed or will guarantee any Merger
Sub

indebtedness outstanding during the period immediately prior to the Merger,
and at all relevant times prior to and including the Effective Date, (i) no
outstanding indebtedness of Parent, Merger Sub, or Target has represented or
will represent equity for tax purposes; (ii) no outstanding equity of Parent,
Merger Sub or Target has represented or will represent indebtedness for tax
purposes; (iii) no outstanding security, instrument, agreement or arrangement
that provides for, contains, or represents either a right to acquire Merger Sub
capital stock (or to share in the appreciation thereof) constitutes or will
constitute "stock" for purposes of Section 368(c) of the Code;

        Target and Merger Sub will report the Merger on their respective U.S.
federal income tax returns in a manner consistent with the opinion set forth
below and will comply with all reporting obligations set forth in the Code and
the Treasury Regulations promulgated thereunder.

        In addition to the above, our opinion is conditioned on the delivery of
an opinion of counsel to Target from Latham & Watkins rendered in connection
with the filing of the S-4 Registration Statement and that such opinion will not
have been withdrawn prior to the Effective Date.

        Based on the foregoing documents, materials, assumptions and
information, and subject to the qualifications and assumptions set forth herein,
we are of the opinion that, if the Merger is consummated in accordance with the
provisions of the Merger Agreement (and without any waiver, breach or amendment
of any of the provisions thereof), the Merger will be a "reorganization" for
U.S. federal income tax purposes within the meaning of Section 368(a) of the
Code and Parent, Merger Sub and Target each will be a "party to the
reorganization" within the meaning of Section 368(b) of the Code.

        Our opinions set forth above are based on the existing provisions of the
Code, Treasury Regulations (including Temporary Treasury Regulations)
promulgated under the Code, published Revenue Rulings, Revenue Procedures and
other announcements of the Internal Revenue Service (the "SERVICE") and existing
court decisions, any of which could be changed at any time. Any such changes
might be retroactive with respect to transactions entered into prior to the date
of such changes and could significantly modify the opinions set forth above.
Nevertheless, we undertake no responsibility to advise you of any subsequent
developments in the application, operation or interpretation of the U.S. federal
income tax laws.

        Our opinion concerning certain of the U.S. federal income tax
consequences of the Merger are limited to the specific U.S. federal income tax
consequences presented above. No opinion is expressed as to any transaction
other than the Merger, including any transaction undertaken in connection with
the Merger. In addition, this opinion does not address any estate, gift, state,
local or foreign tax consequences that may result from the Merger. In
particular, we express no opinion regarding: (i) the amount, existence, or
availability after the Merger, of any of the U.S. federal income tax attributes
of Merger Sub, Parent, or Target; (ii) any transaction in which Merger Sub
Common Stock is acquired or Parent Common Stock is disposed other than pursuant
to the Merger; (iii) the potential application of the "disqualifying
disposition" rules of Section 421 of the Code to dispositions of Merger Sub
Common Stock; (iv) the effects of the Merger and

Parent's assumption of outstanding options to acquire Merger Sub stock on the
holders of such options under any Merger Sub employee stock option or stock
purchase plan, respectively; (v) the effects of the Merger on any Merger Sub
stock acquired by the holder subject to the provision of Section 83(a) of the
Code; (vi) the effects of the Merger on any payment which is or may be subject
to the provisions of Section 280G of the Code; (vii) the application of the
collapsible corporation provisions of Section 341 of the Code to Merger Sub,
Parent, or Target as a result of the Merger; (viii) the application of the
alternative minimum tax provisions contained in the Code; and (ix) any special
tax consequences applicable to insurance companies, securities dealers,
financial institutions, tax-exempt organizations or foreign persons.

        No ruling has been or will be requested from the Service concerning the
U.S. federal income tax consequences of the Merger. In reviewing this opinion,
you should be aware that the opinion set forth above represents our conclusions
regarding the application of existing U.S. federal income tax law to the instant
transaction. If the facts vary from those relied upon (including if any
representations, covenant, warranty or assumption upon which we have relied is
inaccurate, incomplete, breached or ineffective), our opinions contained herein
could be inapplicable. You should be aware that an opinion of counsel represents
only counsel's best legal judgment, and has no binding effect or official status
of any kind, and that no assurance can be given that contrary positions may not
be taken by the Service or that a court considering the issues would not hold
otherwise.

        This opinion is being delivered solely for the purpose of being included
as an exhibit to the S-4 Registration Statement; it may not be used or relied
upon or utilized for any other purpose (including, without limitation,
satisfying any conditions in the Merger Agreement) or by any other person or
entity, and may not be made available to any other person or entity, without our
prior written consent. We do, however, consent to the use of this opinion as an
exhibit to the S-4 Registration Statement and to the use of our name in the S-4
Registration Statement wherever it appears.

        RE:     @HOME CORPORATION TAX REPRESENTATIONS IN CONNECTION WITH THE
                AGREEMENT AND PLAN OF MERGER MADE AND ENTERED INTO AS OF JULY
                12, 1999 AMONG AT HOME CORPORATION, SHOP NEVADA, INC., AND
                iMALL, INC.

Ladies and Gentlemen:

                This certificate is delivered to you in connection with your
rendering of an opinion regarding certain United States federal income tax
consequences of the merger of Shop Nevada, Inc., a Nevada corporation ("Merger
Sub") and wholly owned subsidiary of @Home Corporation, a Delaware corporation
("Parent"), with and into iMALL, Inc., a Nevada corporation (the "Company"),
pursuant to the Agreement and Plan of Merger (the "Merger Agreement") made and
entered into as of July 12, 1999 among Parent, Merger Sub, and the Company, and
for purposes of the opinions so to be delivered by you. Capitalized terms not
defined herein shall have the meanings specified in the Merger Agreement.

                A.      Statements and Representations. The undersigned hereby
certifies and represents on behalf of Parent and Merger Sub and as to Parent and
Merger Sub, after due inquiry and investigation, that the following statements
and representations are true, correct and complete in all respects at the date
hereof and through the Effective Time, and thereafter where relevant.

                1.      The Merger will be consummated in accordance with the
Merger Agreement.

                2.      Neither Parent nor Merger Sub (nor any other subsidiary
of Parent) has acquired or, except as a result of the Merger, will acquire, or
has owned in the past five years, any shares of stock of the Company or other
securities, warrants or instruments giving the holder


<PAGE>   6
Latham & Watkins
Fenwick & West, LLP

Page 2


thereof the right to acquire Company stock or other securities issued by the
Company.

                3.      The fair market value of the Parent Common Stock and
other consideration received by each Company stockholder will be approximately
equal to the fair market value of the Company stock surrendered in the exchange.
In connection with the Merger, no Company stockholders will receive in exchange
for Company stock, directly or indirectly, any consideration from Parent other
than Parent Common Stock and cash in lieu of a fractional share thereof.

                4.      Immediately after the Effective Time, the Company will
hold at least 90 percent of the fair market value of its net assets and at least
70 percent of the fair market value of its gross assets and at least 90 percent
of the fair market value of Merger Sub's net assets and at least 70 percent of
the fair market value of Merger Sub's gross assets held immediately prior to the
Effective Time. For purposes of this representation, amounts paid by the Company
or Merger Sub to dissenters, amounts paid by the Company or Merger Sub to
Company stockholders who receive cash or other property, amounts used by the
Company or Merger Sub to pay Merger expenses, and all redemptions and
distributions (except for regular, normal dividends) made by the Company, and
Merger Sub assets disposed of by Merger Sub prior to the Merger and in
contemplation thereof (including without limitation any asset disposed of by
Merger Sub, other than in the ordinary course of business, during the period
ending on the Effective Time and beginning with the commencement of negotiations
(whether formal or informal) between the Company and Parent regarding the
Merger), will be included as assets of the Company or Merger Sub, respectively,
immediately prior to the Effective Time.

                5.      Except with respect to open-market purchases of Parent
stock pursuant to a general stock repurchase program of Parent that has not been
created or modified in connection with the Merger, neither Parent, nor any
person related to Parent within the meaning of Treasury Regulation sections
1.368-1(e)(3), (e)(4) and (e)(5), has acquired any shares of Company stock in
contemplation of the Merger, or otherwise as part of a plan of which the Merger
is a part, and neither Parent nor any such related person has any plan or
intention to purchase, redeem, or otherwise reacquire any of the Parent stock
issued pursuant to the Merger Agreement following the Merger.

                6.      Prior to the Merger, Parent will be in control of Merger
Sub within the meaning of section 368(c) of the Internal Revenue Code of 1986,
as amended (the "Code").

                7.      Except for transfers described in section 368(a)(2)(C)
of the Code or Treasury Regulation section 1.368-2(k)(2), if any, Parent has no
plan or intention to cause the Company, after the Effective Time, to issue
additional shares of stock that would result in Parent losing control of the
Company within the meaning of section 368(c) of the Code.

                8.      Parent has no plan or intention to (i) liquidate the
Company; (ii) to merge the Company with or into another corporation; (iii) to
sell or otherwise dispose of the stock of the Company except for transfers
described in section 368(a)(2)(C) of the Code or Treasury Regulation section
1.368-2(k); or (iv) to cause the Company to sell or otherwise dispose of any of


<PAGE>   7

Fenwick & West, LLP

Page 3


its assets or any of the assets acquired from Merger Sub, except for
dispositions made in the ordinary course of business or transfers of assets to a
corporation controlled by the Company.

                9.      Merger Sub is a corporation newly formed for the purpose
of participating in the Merger and at no time prior to the Effective Time has it
conducted any business activities or had significant assets.

                10.     Merger Sub will have no liabilities assumed by the
Company, and will not transfer to the Company any assets subject to liabilities,
in the Merger.

                11.     No liabilities of the Company or the Company
stockholders will be assumed by Parent in the Merger.

                12.     Following the Merger, Parent will cause the Company to
continue its "historic business" or use a "significant portion" of its "historic
business" assets in a business, as such terms are described in Treasury
Regulation section 1.368-1(d).

                13.     Except as provided in Section 7.3(a) of the Merger
Agreement, Parent, Merger Sub, the Company, and the stockholders of the Company
will pay their respective expenses, if any, incurred in connection with the
Merger. Any expenses of the Company paid by Parent are expenses described in
Rev. Rul. 73-54, 1973-1 C.B. 187.

                14.     There is no intercorporate indebtedness existing between
Parent and the Company or between Merger Sub and the Company that was issued,
acquired, or will be settled at a discount.

                15.     In the Merger, shares of Company stock representing
control of the Company, as defined in section 368(c) of the Code, will be
exchanged solely for "voting stock" (within the meaning of sections 368(a)(1)(C)
and (2)(E) of the Code) of Parent. For purposes of this representation, shares
of Company stock exchanged for cash or other property originating with Parent or
any person related to Parent within the meaning of Treasury Regulation sections
1.368-1(e)(3), (e)(4) and (e)(5) will be treated as outstanding Company stock at
the Effective Time.

                16.     Cash payments to be made to stockholders of the Company
in lieu of fractional shares of Parent stock that would otherwise be issued to
such stockholders in the Merger will be made for the purpose of saving Parent
the expense and inconvenience of issuing and transferring fractional shares of
Parent stock, and do not represent separately bargained for consideration. The
total cash consideration that will be paid in the Merger to stockholders of the
Company in lieu of fractional shares of Parent stock will not exceed one percent
of the total consideration that will be issued in the Merger to stockholders of
the Company in exchange for their shares of Company stock. The fractional share
interest of each stockholder of the Company will be aggregated, and no
stockholder of the Company will receive cash in lieu of fractional shares in an
amount equal to or greater than the value of one full share of Parent Common
Stock.

                17.     Neither Parent nor Merger Sub are investment companies,
as defined in sections 368(a)(2)(F)(iii) and (iv) of the Code.

                18.     None of the compensation to be received by any
shareholder-employees of the Company and designated as compensation will be
separate consideration for, or allocable to, any of their Company stock. None of
the Parent stock to be received by any shareholder-employees of the Company
pursuant to the Merger will be separate consideration for, or allocable to, any
employment agreement. The compensation to be paid to any shareholder-employees
of the Company will be for services actually rendered and will be commensurate
with amounts paid to third parties bargaining at arm's-length for similar
services.

                19.     The terms of the Merger Agreement and all other
agreements entered into in connection therewith are the product of arm's-length
negotiations.

                20.     The Merger is being undertaken for purposes of enhancing
the business of Parent and for other good and valid business purposes of Parent.

                21.     Company stock will be surrendered in the Merger for
Parent Common Stock (and cash in lieu of fractional shares) pursuant to the
exchange ratio set forth in the Merger Agreement, which was the product of an
arm's-length agreement between Parent and the Company as to the relative fair
market values of the Merger Consideration and the Company Common Stock.

                22.     Neither Parent nor Merger Sub will take any position on
any federal, state or local income or franchise tax return, or take any other
tax reporting position that is inconsistent with the treatment of the Merger as
a reorganization within the meaning of section 368(a) of the Code, unless
otherwise required by a "determination" (as defined in section 1313(a)(1) of the
Code) or by applicable state or local tax law (and then only to the extent
required by such applicable state or local tax law).

                23.     Parent and Merger Sub each hereby undertakes to inform
each of you and the Company immediately should any of the foregoing statements
or representations become untrue, incorrect or incomplete in any respect at or
prior to the Effective Time.

                24.     The undersigned is authorized to make all of the
representations set forth herein.

                B.      Reliance by You in Rendering the Opinion. The
undersigned recognizes and agrees that (i) your respective tax opinions will be
based on, among other things, the representations set forth herein and on the
statements contained in the Merger Agreement and documents related thereto, and
(ii) your respective tax opinions will be subject to certain limitations and

for purposes of the opinions so to be delivered by you. Capitalized terms not

least 70 percent of the fair market value of its gross assets and at least 90

Merger), will be included as assets of the Company or Merger Sub, respectively,
immediately prior to the Effective Time.

                3.      The Company has no plan or intention to issue additional
shares of its stock that would result in Parent losing control of the Company
within the meaning of section 368(c) of the Internal Revenue Code of 1986, as

                4.      No liabilities of the Company will be assumed by Parent
in the Merger.

                5.      Following the Merger, the Company will continue its
"historic business" or use a "significant portion" of its "historic business"
assets in a business, as such terms are described in Treasury Regulation section
1.368-1(d).

                6.      Except as otherwise specifically set forth in the Merger
Agreement, each of the Company and the Company stockholders has paid and will
pay only their respective expenses, if any, incurred in connection with the
Merger, and the Company has not agreed to assume, nor will it directly or
indirectly assume, any expense or other liability, whether fixed or contingent,
of any Company stockholders.

                7.      There is no intercorporate indebtedness existing between
Parent and the Company or between Merger Sub and the Company that was issued,

exchanged solely for voting stock of Parent, and Parent will be in control (as
defined in section 368(c) of the Code) of the Company immediately after the
Effective Time. For purposes of this representation, shares of Company stock
exchanged for cash or other property originating with Parent or any person
related to Parent within the meaning of Treasury Regulation sections

                9.      Neither the Company nor any person related to the
Company within the meaning of Treasury Regulation sections 1.368-1(e)(3),
(e)(4), and (e)(5) has purchased, redeemed or otherwise acquired, or made any

in contemplation of the Merger, or otherwise as part of a plan of which the
Merger is a part.

                10.     At the Effective Time, the Company will not have
outstanding any warrants, options, convertible securities, or any other type of
right pursuant to which any person could acquire stock in the Company that, if
exercised or converted, would affect Parent's acquisition or retention of
control of the Company, as defined in section 368(c) of the Code.

                11.     The Company is not an investment company, as defined in
sections 368(a)(2)(F)(iii) and (iv) of the Code.

                12.     At the Effective Time, the fair market value of the
assets of the Company will exceed the sum of its liabilities, plus, without
duplication, the amount of liabilities, if any, to which the assets are subject.

                13.     None of the compensation received by any
shareholder-employees of the Company and designated as compensation will be
separate consideration for, or allocable to, any of their Company stock. None of
the Parent stock received by any shareholder-employees of the Company in the
Merger will be separate consideration for, or allocable to, any employment
agreement. The compensation paid to any shareholder-employees of the Company
will be for services actually rendered and will be commensurate with amounts
paid to third parties bargaining at arm's-length for similar services.

                14.     The Company is not under the jurisdiction of a court in
a Title 11 or similar case within the meaning of section 368(a)(3)(A) of the
Code.

                15.     Company stock will be surrendered in the Merger for
Parent Common Stock and cash in lieu of fractional shares pursuant to the
exchange ratio set forth in the Merger Agreement, which was the product of an
arm's-length agreement between Parent and the Company as to the relative fair
market values of the Merger Consideration and the Company stock.

                16.     The Company will not take any position on any federal,
state or local income or franchise tax return, or take any other tax reporting
position that is inconsistent with the treatment of the Merger as a
reorganization within the meaning of section 368(a) of the Code, unless
otherwise required by a "determination" (as defined in section 1313(a)(1) of the
Code) or by applicable state or local tax law (and then only to the extent
required by such applicable state or local tax law).

                17.     The terms of the Merger Agreement and all other
agreements entered into in connection therewith are the product of arm's-length
negotiations.

                18.     The Company hereby undertakes to inform each of you and
Parent immediately should any of the foregoing statements or representations
become untrue, incorrect or incomplete in any respect at or prior to the
Effective Time.

     Re:  AGREEMENT AND PLAN OF MERGER DATED AS OF JULY 12, 1999 AMONG
          AT HOME CORPORATION, SHOP NEVADA, INC. AND IMALL, INC.

Ladies and Gentlemen:

     We have acted as counsel to iMALL, Inc., a Nevada corporation (the
"Company"), in connection with the proposed merger of Shop Nevada, Inc., a
Nevada corporation ("Merger Sub") and wholly-owned subsidiary of At Home
Corporation ("Parent"), with and into the Company (such transaction, the
"Merger") pursuant to an Agreement and Plan of Merger dated as of July 12, 1999
(the "Merger Agreement") among Parent, Merger Sub and the Company. Capitalized
terms not defined herein have the meanings specified in the Merger Agreement.
This opinion is being delivered in connection with the filing of the
registration statement on Form S-4 relating to the proposed Merger pursuant to
the Merger Agreement (the "Registration Statement") filed with the Securities
and Exchange Commission ("SEC") on September 28, 1999 to which this opinion
appears as an exhibit.

     In acting as counsel to the Company in connection with the Merger, we have
participated in the preparation of the Merger Agreement and the preparation and
filing of the Registration Statement with the SEC.

     You have requested that we render the opinion set forth below. In rendering
our opinion, we have examined and, with your consent, are relying upon (without
any independent investigation or review thereof) the truth and accuracy, at all
relevant times, of the statements, covenants, representations and warranties
contained in (i) the Merger Agreement (including any Exhibits, Annexes and
Schedules thereto), (ii) the Registration Statement (including the
Prospectus/Proxy Statement filed as part thereof), (iii) the representations
made to us by Parent and Merger Sub, and the Company in their respective letters
provided to us and to Fenwick & West, counsel to Parent, each dated the date
hereof (the "Representation Letters"), and (iv) such other documents and
corporate records as we have deemed necessary or appropriate for purposes of our
opinion.

     In addition, we have assumed, with your consent, that:

     1.   Original documents (including signatures) are authentic, documents
          submitted to us as copies conform to the original documents, and there
          has been

          (or will be by the Effective Time of the Merger) due execution and
          delivery of all documents where due execution and delivery are
          prerequisites to effectiveness thereof;

          2.   The Merger will be consummated in the manner contemplated by, and
               in accordance with the provisions of, the Merger Agreement, and
               will be effective under the laws of the State of Nevada;

          3.   All statements, descriptions and representations contained in any
               of the documents referred to herein or otherwise made to us are
               true, complete and correct, and no actions have been taken or
               will be taken which are inconsistent with such statements,
               descriptions or representations or which make any such
               statements, descriptions or representations untrue, incomplete or
               incorrect at the Effective Time;

          4.   Any statements made in any of the documents referred to herein
               "to the knowledge of" or similarly qualified are true, complete
               and correct and will continue to be true, complete and correct at
               all times up to and including the Effective Time, in each case
               without such qualification; and

          5.   The parties have complied with and, if applicable, will continue
               to comply with, the covenants contained in the Merger Agreement.

     Based upon the foregoing, and subject to the qualifications and limitations
stated herein, we are of the opinion that the Merger will constitute a
reorganization under section 368(a) of the Internal Revenue Code of 1986, as
amended (the "Code").

     In addition to the matters set forth above, this opinion is subject to the
exceptions, limitations and qualifications set forth below.

          1.   This opinion represents our best judgment regarding the
               application of United States federal income tax laws arising
               under the Code, existing judicial decisions, administrative
               regulations and published rulings and procedures. Our opinion is
               not binding upon the Internal Revenue Service or the courts, and
               there is no assurance that the Internal Revenue Service will not
               assert a contrary position. Furthermore, no assurance can be
               given that future legislative, judicial or administrative
               changes, on either a prospective or retroactive basis, would not
               adversely affect the accuracy of the conclusions stated herein.
               Nevertheless, we undertake no responsibility to advise you of any
               new developments in the application or interpretation of the
               United States federal income tax laws.

          2.   No opinion is expressed as to any transaction other than the
               Merger as described in the Merger Agreement or to any transaction
               whatsoever, including the Merger, if all the transactions
               described in the Merger Agreement are not consummated in
               accordance with the terms of the Merger Agreement and without
               waiver or breach of any provisions thereof or if all of the
               representations, warranties, statements and assumptions upon
               which we have relied are not true and accurate at all relevant
               times. In the event that any one of the statements,
               representations, warranties or assumptions upon which we have
               relied to issue this opinion is incorrect, our opinion might be
               adversely affected and may not be relied upon.

     This opinion is rendered to you in connection with the filing of the
Registration Statement with the SEC and is not to be used, circulated, quoted or
otherwise referred to or relied upon for any other purpose without our express
written permission. In addition, this opinion may not be relied upon by or
furnished to any other person, firm, corporation or entity without our prior
written consent. We consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to our firm name therein under the
caption "The Merger -Material United States federal income tax consequences of
the Merger." In giving this consent, we do not admit that we are within the
category of persons whose consent is required under Section 7 of the Securities
Act of 1933, as amended, or the rules or regulations of the SEC promulgated
thereunder.

                                Very truly yours,
